This article introduces problematics of work load and stress. As they have become parts of the work-life balance, they equally affect the quality of life and the wellbeing of a person. Stress load is being induced by both adverse work conditions and work environment which the employee is not able to manage for a longer period of time despite his increased efforts.

Opis:

Post-traumatic stress disorder (PTSD) is observed as a group of post-traumatic mental and physical clinical symptoms. It affects soldiers returning from missions as well as victims of different types of disasters. The combat stress symptoms are follow-up of a triggering factor. The reaction of the limbic system associated with the emotional state circulation in the Papez area, causing the variety of vegetative effects, especially circulatory, plays a significant role. Consequences of the combat stress apply to mental and emotional changes, a dynamic stereotype and have indirect effects within individual’s family life and his/her immediate surroundings. Providing people suffering from combat stress syndromes with psychological and psychiatric care is crucial.

RESEARCH OBJECTIVE: The article addresses important and current issues regarding stress at work of contemporary managers and the implications of stress, including for family life. The purpose of the article is to indicate the causes and effects of managers’ professional stress. THE RESEARCH PROBLEM AND METHODS: The research problem is an attempt to answer the question – how stress affects managers in professional and private life? Based on the literature of the subject and in relation to the results of selected surveys, the authors prove that professional stress in the case of managers adversely affects not only the professional environment in which the manager works, but also has a bearing on the family’s functioning.THE PROCESS OF ARGUMENTATION: Professional stress is an increasingly common phenomenon in modern organizations. In the case of managers, it is usually the result of their weakened resilience in overcoming and solving the difficulties, long-term fatigue and emotional strains they experience at work. RESEARCH RESULTS: Stress affects the entire manager’s surroundings negatively. At work, it is increased absenteeism, more mistakes made, emotional arousal or loss of self-confidence. In family life, this is excessive nervousness, physical and mental tension that acts destructively on family members, lack of interest in the affairs of loved ones and aggression.CONCLUSIONS, INNOVATIONS, AND RECOMMENDATIONS: Employers and personnel departments in order to level the level and effects of stress should initiate research aimed at identifying the causes of manager’s stress. Training in stress management and undertaking activities that reduce the stressfulness of the work environment, such as changing the scope of tasks, goals or responsibilities, are important.

W pracy przedstawiono zależność współczynnika intensywności naprężeń w ostrym wierzchołku otworu w kształcie rombu od kąta wierzchołkowego. Rozważono dwa przypadki obciążenia - jedno- i dwukierunkowe rozciąganie płaszczyzny. Wykorzystując metodę osobliwych równań całkowych otrzymano rozwiązanie dla rozciąganej płaszczyzny sprężystej osłabionej rombowym otworem o wierzchołkach zaokrąglonych łukiem o małym promieniu krzywizny. Przejście graniczne w rozwiązaniu numerycznym umożliwiło uzyskanie wartości współczynników intensywności naprężeń w odpowiednich ostrych narożach dla dowolnych kątów rozwarcia wierzchołka otworu.
The unified approach to solve problems of stress concentration around sharp and rounded diamond shaped hole in elastic plane based on singular integral equation method was proposed. At first, the problem was solved for an elastic domain with diamond hole with rounded vertex of large curvature. The method based on passage to the limit (when curvature radius tends to zero), was used to obtain stress intensity factor at the vertex of sharp diamond hole in a plane under tension. The numerical results of stress intensity factors for a diamond hole of arbitrary vertex angle were discussed.

This paper contains an analysis of the determinants of predispositions of individuals to cope with stress in adulthood, very likely shaped in childhood. The theoretical part defines stress and ways to cope with it and describes the conclusions reached to date of studies on attachment styles determinants to cope with stress. Presents the results of the author’s own research showing the preferences of choosing different strategies to cope with stress depending on an attachment style shaped in childhood. The research conducted in 2013 and 2014 was participated by 180 women and 180 men aged 20-40 (M = 28.99, SD = 4.23), living in the Zachodniopomorskie and Lubuskie Voivodeships in Poland. Participants filled in questionnaires defining their ways of coping with stress and their attachment style. The research results obtained show that the respondents who the most frequently manifest active coping with stress and seeking support in difficult situations come from families that built in their child a secure attachment style. Helplessness and avoidant behaviours are more often evinced in stressful situations by the respondents brought up in families who built an anxiety-ambivalent and an avoidance attachment style.

Opis:

The profession of a kindergarten teacher is particularly stressful due to the complex tasks within the didactic, educational and caring functions. To recognise the problem of stress of this professional group, the research was done to answer the following questions: What is the level of stress of teachers depending on the seniority of teaching and what factors are the cause of stress. The research using the diagnostic survey method covered 440 respondents with different seniority. Studies have shown that 35% of teachers experience above-average stress levels. The amount of stress is individually diversified, and the way it is experienced depends on many factors that are perceived as particularly burdensome and difficult to overcome. They are connected with time pressure, physical nuisance, a feeling of insufficiency of prizes, fulfilling didactic and educational functions. Teachers are stressed by the large amount of work outside the hours spent with children, by underestimating the profession, lack of time to support the development of children requiring special care and compensating for their shortages as well as staying in constant noise.
Zawód nauczyciela przedszkola ze względu na wykonywanie złożonych zadań w obrębie funkcji dydaktycznej, wychowawczej i opiekuńczej, należy do szczególnie stresogennych. Aby poznać problematykę stresu tej grupy zawodowej, podjęto badania mające na celu udzielenie odpowiedzi na pytania: Jaki jest poziom stresu nauczycieli w zależności od stażu pracy pedagogicznej oraz jakie czynniki są przyczyną stresu. Badaniami z wykorzystaniem metody sondażu diagnostycznego objęto 440 respondentek o różnym stażu pracy zawodowej. Badania wykazały, że ponadprzeciętnego poziomu stresu doświadcza 35% nauczycielek. Wielkość stresu jest indywidualnie zróżnicowana, a sposób jego przeżywania uzależniony jest od wielu czynników, które są postrzegane jako szczególnie obciążające i trudne do przezwyciężenia. Mają one związek m.in. z presją czasu, uciążliwościami fizycznymi, poczuciem niedostatku nagród, pełnieniem funkcji dydaktyczne i wychowawczej. Nauczycieli stresuje duży nakład pracy poza godzinami spędzonymi z dziećmi, niedocenianie zawodu, brak czasu na wspomaganie rozwoju dzieci wymagających szczególnej troski i wyrównywanie ich niedoborów, przebywanie w ustawicznym hałasie.

Opis:

Every day, contemporary youngsters face limitations and exploit the possibilities offered by the global reality. The conditions which characterise the beginning of the 21st  century are vastly different from the times in which their parents and grandparents grew up. It would be futile to look for any kind of order in the world today, be it political, moral or economic one. The young, who experience temporariness and constant change, have to develop their own measures of coping with post-modern challenges. The principal issue presented in this paper is the occurrence of information and relational stress. The fast pace of local migration, the overload of information, the weakening of social bonds and the relationships lasting “here and now” are the shameful markers of the lifestyle of young people. These are also constitutive traits which distinguish contemporary teenagers from their predecessors. In the subsequent section, the author considers excessive consumption as a modern form of cult. Finally, attention is drawn to the incoherent and continually evolving identity of individuals, who seek to determine their place within the contemporary social structures.

The aim of the present paper is to discuss the problem of Russian word stress evolution within verb forms, which has been observed for the last twenty five years. There are certain groups of verbs, in which the word stress changes its place and this process can be caused by different tendencies (intralinguistic and extralinguistic). The stress variants can be observed in the monosyllabic verbs such as дать, пить, the short forms of participles or in the past tense forms. To show the changes in accentuation, the author of the article compares two orthoepic dictionaries, published at the end of the 20th century and at the beginning of the 21st century.

The paper deals with stress management in the caring professions, in which employees encounter different types of clients and are often confronted with unexpected, tense, and demanding moments that can momentarily shift the employees from their balance. It is necessary for every individual who works in the caring profession to be able to manage their emotions and difficult stressful situations. They should roughly know how they react in stressful situations, what helps them cope with them and how to quickly get into mental well-being and balance.

Stress is apply to everyone, independently on age, so important is recognition main stressors and ways of copy with stress, especially on young people, and that was the purpose of questionnaire research during music festivals. Method: Author’s questionnaire. We researched 1131 visitors music festivals: Festival name R.Riedla bad Przystanek Woodstock. 45% of them were women and 55% men; medium age +/ – 20 years. Results: Researched people declared their level of stress on 3-4 points in 6-points scale. 2/3 of them claimed that surroundings is a couse of stress. 2/3 young people said that their knowledge about stress is not enough, and only 2% of them use specialized help. In difficult life situations, if they want to cut down their level of stress, they the most often use alcohol. Conclusion: Knowledge about stress is not enough. Women and men have different ways of copy with stress. The most often young people exert passive methods of liquidate everyday difficulties.

Opis:

This contribution deals with secondary stress in Modern Standard German (MSG) and its relevance in affixation using the verbal prefix ver-. While the pattern ver+ stressed syllable or ver+ schwa is allowed, ver+ unstressed syllable is avoided in contemporary German (see also Kaltenbacher 1999). Diachronical data reveals that in earlier stages this prosodic restriction was not as strong as in MSG. The consistency with which verbs with the pattern ver+ unstressed syllable are discarded in MSG (confirmed by look-ups in corpora and dictionaries) is a strong argument for the hypothesis that the relinquishment is due to a form of blocking related to the stress properties of the direct base: The affix ver- needs a direct base with some initial prominence, that is with primary or secondary stress. The only (apparent) exception to this stress condition is a base containing a schwa syllable which seems to be “invisible” for the stress-seeking prefix. Verbal derivation with the prefix ver-demonstrates that the stress properties of the base have to be taken into account also with regard to secondary stress. The data provided in this paper can count as further evidence for the existence and relevance of secondary stress in Modern Standard German and its interaction with morphology

Opis:

The deformation of a part occurring in the process of grinding directly influences its exploitation and quality parameters. The instability of shape and size, which occurs due to an imbalance of residual stress, can be the one of the major causes of deformation of a part. The decrease in stress slows down the deformation process. Considering the regularities of heat source intensity dependence on the grinding modes, it can be asserted that with increasing grinding depth and grinding wheel hardness, the value increases and it decreases with a growth in a speed of the part and the use of cooling. The higher the heat removal is and the better lubricant properties of the liquid are, the more significant the decrease in is. Changing these values allows regulation of the residual stresses. As a result of the research on determination of deformations, it is recommended to reduce thermal deformations by considering the geometric size of a plate to be machined, linear expansion coefficient of plate material and an allowance for nonflatness from thermal deformations. The value of nonflatness from thermal deformations is directly proportional to linear expansion coefficient of plate material and its square overall dimensions.

dealing with stress

Opis:

The appearance of a child with a disability is always a source of tremendous stress in the family. This problem is particularly evident in the case of an autistic child because of its unpredictable and untypical development. Every person during their life develops certain mechanisms to deal with difficult situations. According to Lazarus and Folkman (1987), dealing with stress mainly relies on specific intellectual activities and appropriate actions to control the requirements assessed by the person as burdensome or beyond his/her current possibilities. There are many ways of dealing with stress. The most common strategies include those focused on solving the problem (SSZ), emotional overreaction (SSE) and avoidance of stress (SSU) by engaging in substitute activities (ACZ) or seeking social interaction (CSA). It is assumed that an effective way to deal with stress consists in relating the needs and capabilities of an individual. The aim of this article was to investigate the ways of dealing with stress among 130 parents of autistic children.

Opis:

Molecular oxygen (O2), constituting the basis of life on Earth, is classified as a substance with oxidizing properties. Reacting with organic compounds, it leads to their oxidation and at the same time participates in reduction processes. In aerobic organisms, over 90% of oxygen undergoes a total four-electron reduction to produce water molecules (O2 + 4 H+ + 4e- → 2 H2O). The remaining 10% of oxygen, however, is not fully reduced, which results in the production of molecules referred to as reactive oxygen species (ROS). In high concentrations ROS can interact with cellular components (DNA, proteins and lipids), leading to the oxidation of these macromolecules. The resulting oxidation products interfere with the proper functioning of the body by influencing gene expression, intercellular signaling and apoptosis. These changes have been observed in numerous pathological conditions, such as neurodegenerative, cardiovascular, metabolic, autoimmune diseases, and cancer. However, in the context of evolution, living organisms developed specialized repair mechanisms to prevent cellular accumulation of the products of DNA, protein and lipid oxidation, including enzymatic mechanisms (e.g. nucleases, proteases, phospholipases) or removal of damaged DNA, proteins and lipids by apoptosis or autophagy. This article briefly discusses the mechanisms of oxidative modification of cell components and the main repair systems responsible for the removal of lesions in cells by oxidative damage.

Opis:

Hydrogen sulfide (H2S) is an important signaling molecule involved in several stress-resistance processes in plants, such as drought and heavy metal stresses. However, little is known about the roles of H2S in responses to chilling stress. In this paper, we demonstrated that chilling stress enhance the H2S levels, the H2S synthetase (L-/D-cysteine desulfhydrase, L/DCD) activities, and the expression of L/DCD gene in Vitis vinifera L. ‘F-242’. Furthermore, the seedlings were treated with sodium hydrosulfide (NaHS, a H2S donor) and hypotaurine (HT, a H2S scavenger) at 4°C to examine the effects of exogenous H2S on grape. The results revealed that the high activity of superoxide dismutase and enhanced expression of VvICE1 and VvCBF3 genes, but low level of superoxide anion radical, malondialdehyde content and cell membrane permeability were detected after addition of NaHS. In contrast, HT treatment displayed contrary effect under the chilling temperature. Taken together, these data suggested that H2S might be directly involved in the cold signal transduction pathway of grape.

Opis:

Salt stress is a major abiotic stress that limits agricultural productivity in many regions of the world. To understand the molecular basis of the salt stress response, two wheat (Triticum durum Desf.) cultivars, Karim and Azizi, which are of agronomic significance in Tunisia, were grown under non-saline and saline conditions (100 mM). Leaves and roots of control and salt-stressed plants were harvested after 11 days of salt treatment. Karim cultivar may behave as a typical Na+ include, which compartmentalizes Na+ within the leaf cell vacuoles where it could be used as an osmoticum to lower the osmotic potential necessary for the maintenance of the plant hydric status. While, accumulation of K+ was greater in Karim cultivar compared to Azizi, in both organs, presenting an important manifestation of salinity tolerance. Significant changes in metabolism of antioxidative system were observed, with an increase in protein tyrosine nitration, which indicates that salinity stress induces a nitro-oxidative stress.

Little is known as to what extent the pandemic lockdown has changed the perceived level of stress and stress-coping strategies. In response to this gap we present the results of quantitative and qualitative studies on stress levels and coping with stress conducted among Polish adults during the COVID-19 lockdown. The first study indicates that the lockdown has changed stress appraisal moderately, and it has also affected stress-coping strategies in various areas. The second study reveals miscellaneous reasons for stress appraisal (health, economic, political, social, freedom restriction, and religious). Participants perceived pandemic and lockdown as a moderate stressor, more as a challenge than a threat. Moreover the avoidant style recognized as the most adaptive reaction on stress in our study, confirms that people have a natural ability to adapt to unpredictable and unexpected situations like COVID-19 lockdown.

Opis:

Plants exposed to osmotic stress exhibit changes in their physiology and metabolism. In general, osmotic stress reduces water availability and causes nutritional imbalance in plants. In the present study, we compared the response of cucumber (Cucumis sativus L. var. Władko F-1) to ionic (100 mmol•dm-3 NaCl) and osmotic stress (10% PEG 6000). Both stress factors reduced significantly fresh and dry weight of 7-day-old cucumber seedlings. Under PEG treatment reduction of cucumber dry mass was lesser than in fresh mass, whereas under salt stress decrease in dry weight of cucumber shoots was more pronounced than in fresh mass. Salt stress caused severe decrease in nitrate concentration and activity of nitrate reductase (NR). In cotyledons nitrate content declined to 17% of the control and similar reduction in NR activity was observed. In the roots, observed changes were not so drastic but there was also strong interaction between reduction in nitrate content and NR activity. Under 10% PEG both nitrate concentration and NR activity in cucumber roots were significantly higher in comparison to control plants. In cotyledons NR activity was significantly lower than in control plants, while decrease in nitrate content was not statistically significant. Phosphate concentration did not change significantly in cucumber cotyledons but increased in roots treated both NaCl (32% increase) and PEG (53% increase). Similar tendencies were observed in acid phosphatase activity. Obtained results indicated that osmotic and salt stresses evoke differential responses, particularly in growth reduction and nitrogen metabolism in cucumber seedlings.

Opis:

With the developing of science and technology the use of gears has become more common in all the upcoming industries. Accessory units used in aircraft provide the power for hydraulic, pneumatic and electrical systems in addition to providing various pumps and control systems for efficient engine operation. The design of an effective and reliable gearing system is governed, amongst other factors, by its ability to withstand high root bending stress (RBS) and surface contact stress(SCS). A number of authors have utilized thefmite element method to predict RBS and SCS in gears. This paper presents the utilization of a three-dimensional (3D), finite element method (FEM) to conduct RBS and SCS calculations of a pair ofspur gears. Firstly a pair of parallel spur gears without errors and tooth modifications is defined in a CAD system. Then, MES analysis is conducted. Using FEM to calculate the RBS the load is applied as a force to the tip of the gear, it is modeled as a linear force uniformly distributed along the face width and perpendicular to the tooth surface. The SCS is considered as nonlinear contact analysis, where the contact of the pair of gears is assumed on teeth flanks. The tooth RBS and SCS of the same pair of gears are calculated and presented. Gears with wrought alloy steel are considered. The results are compared with the ISO standards, Levis formula and Hertz equation. The analysis was made for applied moment equal: 600[Nm], 1200[Nm] and 1600[Nm]. It was found that the calculated results are comparable. Finally, an example of calculating a pair of spur gears is given in the paper.

This paper presents the results of a rheological test of a commercial magnetorheological (MR) fluid (MRF-132DG). The research includes the problem of measuring and interpreting limit stresses under conditions close to the magnetic saturation of the fluid. Four different limit stresses were determined, two related to the yield point and two related to the flow point. Methods for determining limit stresses, especially due to excitation conditions, were also analysed. The aim of this study is to determine the effect of selected parameters on the values of limit stresses of the selected MR fluid. An additional objective is to highlight the problems of defining and interpreting individual limit stresses in MR fluids, particularly in the context of selecting the values of these stresses for the purpose of modeling systems with MR fluids.

Opis:

Artykuł poświęcony jest tematyce stresu zawodowego, dotyczącego zawodów o charakterze edukacyjnym i wychowawczym. Napięcie wzbudzają między innymi przekonania społeczne o uprzywilejowanej pozycji zawodowej dydaktyków, konieczność realizacji licznych, często sprzecznych czy nierealistycznych oczekiwań oraz postawy prezentowane przez uczniów, rodziców czy przełożonych. Problematyczne okazuje się także utrzymanie równowagi pomiędzy życiem osobistym a zawodowym oraz uciążliwości wynikające z warunków fizycznych. W świetle obecnej wiedzy na temat możliwości radzenia sobie ze stresem wyróżnić możemy określone środki zaradcze, których wdrożenie może przynieść poprawę funkcjonowania i dobrostanu nauczycieli. Kwestia ta jawi się jako istotna zwłaszcza w świetle wiedzy o wpływie konsekwencji napięcia nie tylko na osobę nauczyciela, ale także odbiorcy jego działań – ucznia.
The article is devoted to the issue of occupational stress, regarding educational professions. The tension is caused, among others, by social beliefs related to the privileged professional position of educators, the necessity to implement numerous, often contradictory or unrealistic expectations, as well as the attitudes presented by students, parents or superiors. What is more, maintaining balance between personal and professional life and the inconveniences resulting from physical conditions also turns out to be problematic. In the light of current knowledge on the possibilities of coping with stress, we can specify certain counter-measures, the implementation of which can bring improvement in terms of teachers’ functioning and well-being. This issue is important especially in the light of knowledge about the impact of the tension consequences not only on the teacher but also on the recipient of their actions – the student.

Opis:

The tested material consisted of grapevine Vitis californica stratified seeds germinated under optimum conditions (+25°C in water), under osmotic stress (-0.2 MPa in PEG solution) and submitted to recovery after stress (+25°C in water). The germinating seeds were determined to contain tannins, catechins and the following phenolic acids: gallic, caffeic, p-coumaric and ferulic. The acids occurred in free, ester- and glycoside-bound forms. The dominant form of phenolic acids was the ester-bound fraction. Gallic acid was the most abundant phenolic acid in germinating seeds, while ferulic acid appeared in the smallest amounts. Our analysis of tannins demonstrated that osmotic stress depressed their concentration. Presence of catechin group compounds such as catechin and epicatechin was also determined. In each sample epicatechin was dominant. The total concentration of catechin increased under stress conditions and declined during post-stress recovery. Catechins are a constituent of tannins and their increase under osmotic stress is most probably caused by the breakdown of some tannins in seeds germinating under stress conditions. Samples submitted to osmotic stress were also found to contain less of total phenolic compounds, whereas in samples which underwent post-stress recovery the total level of phenolic compounds increased. Compared to extracts from seeds germinating under optimum conditions, osmotic stress depressed the capacity of extract to scavenge DPPH● (2,2-diphenyl-1-picrylhydrazyl) and ABTS●+ – 2,2-Azino-bis (3-etylbenzothiazoline-6- -sulfonic acid) free radicals, but the antioxidant activity rose in seeds submitted to recovery after stress. Positive correlation was therefore demonstrated between the total content of phenolic acids in germinating grapevine seeds and the reducing power of extracts obtained from these seeds and their free radical scavenging activity. The results suggest that osmotic stress inhibits the activity of antioxidizing enzymes in germinating grapevine seeds. Thus, the antioxidative defence system is largely blocked under osmotic stress. It seems that a very high oxidoreductive potential in grapevine tissues prior to occurrence of osmotic stress is essential for maintaining proper homeostasis of oxidation and reduction reactions.

Opis:

When talking about burnout syndrome, it is important to highlight the fact that burnout syndrome is the result of long-term chronic stress. In this context, it is important to define stress as a phenomenon that inherently belongs to the life of living beings and therefore of man. This process can be understood as a process that is still developing (Kebza, Šolcová, 1998). Canadian physiologist Hans Selye defined stress as a condition manifested in the form of a specific syndrome, which represents the sum of all non-specific changes induced within a given biological system (Selye, 1996). Košč (2003) defined stress as a non-specific response to any demand that is placed on it. It may also be understood as a general adaptation syndrome a phylogenetic development developed by the response of higher organisms to a life-saving, promising preparation for an attack or escape. fight or flight. The stress itself can not be avoided, because this effort would be stressful by itself. If we look at the issue from a physical point of view, the very concept of stress means the pressure that acts on the body and causes its distortion. From a psychological point of view, it means a certain amount of effort, that is, the demands placed on the individual’s physical and mental energy. Goldstein (1993) states that stress can also be seen as a threat and disruption of the body’s homeostasis. W.B.Cannon (1915) defined the alarm theory of emotions as the response of the organism to stress by adrenergic activation with metabolic consequences for energy to fight or flight (Kryl, 2004). In terms of stress alone, it is important to define terms such as stressors and salutaries. All negative living factors leading to stress itself are called stressors. They can be divided into: • external stressors (noise, sensory deprivation, hazard); • Barriers that hinder satisfying primary needs (food, sleep and rest) • Performance-related burdens (timing, extreme demands, or monotonous work) • social stressors (interpersonal and social problems), • Conflicts (Křivohlavý, 2003). In this context, the stressor can also be an activity related to a certain risk, sense of responsibility and competition as well as situations related to the examination, bankruptcy and conflicting situations. Physical or natural factors can be accidents, cold, noise, heat, time-consuming activity, risk-related activity, expectation of threat, inadequate qualification due to tasks, cognitive, emotional or social deprivation, hostility to the social environment, lack of privacy, or too many interactions (Verešová, 2007).

Soldiers preparing for missions abroad should cover both training for specific tasks and mental preparation for dealing with the stress overload. This article includes the overview of various stressful situations, which in different ways and with different strength may affect soldiers’ mental condition. Starting with everyday stressful situations, through stress which is triggered by the information about going on military mission abroad until combat stress, stress-related critical incidents and even stress connected with a return to their mother country and readaptation to family and professional roles. This overview presents how different reactions to stressful factors and situations grow and provides some information on how to minimise the consequences of experienced stress. It may serve as a basis for psychological training programs for soldiers going on missions abroad and for their families.

Opis:

This paper deals with the behavior of a crack in the residual stress field induced by the butt weld in a wide plate. It is known that the distribution form of residual stress has similarities regardless of the welding process, although the size and the magnitude of the residual stress depend largely on the welding process. Stress intensity factor and stress redistribution induced by the crack extension were calculated for a crack with arbitrary length and location. The stress redistributions caused by crack extension obtained by the present analysis showed good agreement with the experimental data. Fatigue crack propagation behavior in the residual stress field reported by Glinka was also examined from ΔK point of view. The effect of residual stress on the fatigue crack propagation rate is considered to be the effect of varying mean stress. It was shown that fatigue crack propagation rate is estimated by the following equation with reasonable accuracy.
da/dn=CΔF^α(1+ σ₀/Δσ F_res)
In the above equation, material constants C and α of Paris’s law are experimentally obtained by using specimens without the weld joint.

Wyniki badania wskazują, że studiująca młodzież prawidłowo rozumie pojęcie stresu dziecięcego, a także trafnie wymienia charakterystyczne reakcje stresowe w eksplorowanych obszarach. Z uwagi na specyfikę kierunku oraz przyszłej profesji badanych jest to niezwykle ważne. Rzetelna wiedza w tym zakresie stanowi cenny zasób wpisujący się w kompetencje zawodowe umożliwiające szybkie i responsywne reagowanie na potrzeby podopiecznego doświadczającego dystresu zazwyczaj prowadzącego do patologicznych następstw.
Contemporary conditions and realities make children encounter stressful situations in their daily lives, stemming from the increasing pace of life, an overload of tasks, rising expectations from their immediate surroundings, and various educational environments. The aim of this article is to present, based on the literature on the subject, a scientific explanation of the concept of stress and its typical symptoms in the light of expert research. Additionally, the paper presents the results of an original study conducted among 103 pedagogy students. The study aimed to understand how respondents perceive the concept of childhood stress and to identify their knowledge of the physiological, cognitive, emotional, and behavioural symptoms of stress experienced by children in the modern world. The study results indicate that the studying youth correctly understands the concept of childhood stress and accurately identifies characteristic stress reactions in the explored areas. Due to the specificity of the field of study and the future profession of the respondents, this is extremely important. Reliable knowledge in this area is a valuable resource that is part of professional competencies, enabling quick and responsive response to the needs of wards experiencing distress, usually leading to pathological consequences.

Opis:

W pracy przedstawiono rozwiązanie zagadnienia rozciąganej płaszczyzny osłabionej otworem o ksztacie owalnym z wierzchołkami o dowolnej krzywiźnie. Wykorzystano metodę jednolitego podejścia do rozwiązywania zagadnień koncentracji naprężeń wokół karbów ostrych i zaokrąglonych. Dla parametrów, charakteryzujących geometrię otworu, zmieniających się w bardzo szerokim zakresie obliczono współczynniki koncentracji naprężeń w wierzchołku owalu. Wykorzystując zależność wiążące współczynniki koncentracji naprężeń ze współczynnikami intensywności naprężeń, wyznaczono wartości współczynnikow intensywności dla odpowiedniego otworu o wierzchołkach ostrych. Przeprowadzając porównanie wyników obliczeń ze znanym rozwiązaniem analitycznym dla otworu soczewkowego, wykazano nie tylko dużą precyzję zastosowanej metody lecz również jej uniwersalność i efektywność. Otrzymane rezultaty posłużyły do skonstruowania przydatnych w praktyce inżynierskiej wzorów aproksymacyjnych służących do oszacowania wartości współczynnikow intensywności naprężeń w wierzchołku soczewki oraz koncentracji naprężeń w wierzchołku otworu owalnego.
In the paper the application of the unified approach method to solve problems of stress concentration around sharp and rounded oval hole in elastic plane was presented. The stress field distribution was obtained for various vertex angles and curvature radii using singular integral equation method. The method based on passage to the limit (when curvature radius tends to zero), was used to obtain stress intensity factor at the vertex of sharp lens hole in a plane under tension. Accuracy of the new method was analyzed by comparing numerical results of stress intensity factors to well known analytical solution. The approximation formulas for estimation of stress intensity and concentration factors were presented.

Artykuł poświęcony jest problematyce stresu szkolnego. W pierwszej części tekstu omówiono zagadnienia teoretyczne: najczęstsze sposoby definiowania i rozumienia stresu, jego przyczyny i skutki. Następnie scharakteryzowano stres szkolny, wskazując jego objawy, główne źródła i konsekwencje nadmiernego napięcia przeżywanego przez uczniów w szkole. Przedstawiono także założenia badań empirycznych, zrealizowanych metodą sondażu diagnostycznego w grupie 440 uczniów w wieku 12–14 lat, których celem było poznanie opinii uczniów na temat wybranych aspektów stresu szkolnego. W artykule zreferowano wyniki badań dotyczących problemu obecności i natężenia stresu szkolnego w codziennym doświadczeniu dzieci i młodzieży. Uzyskane dane wskazują, że badani przeżywają stres szkolny o różnej częstotliwości i poziomie natężenia. Najwięcej jest uczniów z przeciętnym i niskim poziomem stresu (ok. 40% dla każdego z tych poziomów), poziom wysoki dotyczy blisko 20% respondentów. Zarejestrowano wzrost odsetka uczniów z wysokim poziomem stresu w gimnazjach w porównaniu do szkół podstawowych, zauważono też, że nadmierne napięcie częściej dotyczy dziewcząt, które odczuwają stres bardziej intensywnie. Przedstawiono również deklarowane przez uczniów symptomy stresu w obszarach: fizjologicznym, emocjonalnym, poznawczym i behawioralnym. Na podstawie analizy uzyskanego materiału empirycznego podjęto próbę ich interpretacji i sformułowano wnioski praktyczne.
The article concerns the problem of school stress. In the first part, theoretical issues are discussed: the most common definitions and understanding of stress, its causes, and effects. School stress is then characterized: its symptoms and main sources are presented as well as the consequences of excessive strain felt by students at school. The assumptions of empirical research on school stress as viewed by students are also presented. The research was conducted through a diagnostic survey on a group of 440 students aged 12–14. The article presents the results of the research on the problem of stress and its intensity in students’ daily school life. The data obtained in the research shows that the students experienced stress with different frequency and intensity. Most of the students experienced average and low levels of stress (ca 40% for each level), and 20% of the students were under high levels of stress. An increased number of highly stressed students was observed in middle schools compared to primary schools. Also, it was noticed that more girls than boys suffered from intense tension. Symptoms of stress – physiological, emotional, empirical, and behavioral ones - declared by the students are also presented. Interpretation and conclusions are made based on the analysis of the empirical material.

Parental Stress Scale

Opis:

The article describes the procedure of adaptation and psychometric parameters of the Polish version of the Parental Stress Scale (PSS). The PSS sees parenting as a source of both strength and stress. Therefore, assessing parenting experiences with the PSS enables one to measure both the level of parenting stress and parental satisfaction. The PSS has been shown to be reliable and moderately correlated with standardized measures in expected directions, suggesting its validity (Berry & Jones, 1995). In this research, we investigated parenting stress in a non-clinical, population-based sample of parents and examined the psychometric properties of the Polish version of the PSS. We analysed reliability, as well as factorial and convergent validity. Two online studies were conducted. In Study 1, parents (126 mothers and 124 fathers) were sent a survey link and requested to fill in the PSS, the Perceived Stress Scale, the Parenting Stress Index, the SF-36v2 Health Survey, and the Family Resilience Assessment Scale. Study 2 was conducted to check the PSS structure once again and assess its reliability. Parents (111 mothers and 41 fathers) filled out the Polish 16-item version of the PSS (PSS-PL). The PSS-PL demonstrated adequate convergent validity with expected correlations with parenting stress, perceived stress, quality of life, and family resilience. Our results suggest that the PSS-PL is a reliable and valid measurement tool to evaluate the level of parental stress in Polish parents. Implications of the findings and study limitations are discussed.

The concept of gender role stress is based on the assumption that some women and men might have problems adapting to the feminine and masculine gender roles imposed on them by society. 1515 people took part in the study to verify feminine and masculine gender role stress models in the Polish population. The studies show that the five-factor feminine and masculine stress models are justified. Men display higher stress connected with 'physical inadequacy' than women, whereas women score higher on other subscales associated with feminine and masculine gender role stress. Gender role stress is more connected with femininity. Personality correlates of gender role stress were sought.

Opis:

Background: Stress is an inseparable attribute of sports activities. The answer to the question of how to effectively cope with stress in a competition is one of the most important challenges of sports psychology. The aim of this research is to analyze the stress-management strategies used by football players. Methods: Participants in the study were 32 students of physical education specializing in football and 39 students of management, aged between 19 and 27 years (M = 21.41, SD = 1.76), including 24 women (34% of all respondents). Coping strategies were assessed through application of the multi-dimensional COPE inventory. Results: In comparison with the sample of management students, the group of footballers use the strategy of positive reinterpretation and growth significantly more often, and less frequently use alcohol or other psychoactive substances in a stressful situation. Women use the strategy of seeking emotional support significantly more often than men, while significantly less often using psychoactive substances and humor. Conclusion: This research revealed that trainers and sport psychologists should take into account gender differences and the specificity of the sports discipline of the athletes when working on selection of the best strategies for coping with stress during competitions.

Opis:

The aim of the paper is the assessment of the efficiency of anti-oxidative system in spinach plants growing in the substratum polluted with zinc. The assessment was conducted on the basis of changes of reduced glutathione (GSH) form concentration in the plant aboveground organs. Spinach plants, ‘Matador’ c.v., were cultivated in soils contaminated with zinc in two pot experiments conducted in 2010 and 2011. The experimental substratum was light, slightly soil with granulometric composition of sandy silt loam. Zinc in the acetate form, was supplied to the soil in four doses corresponded to this metal critical concentrations in soil with 0, I, II and III degrees of pollution with this element according to IUNG classification. Simultaneously, the control with natural Zn content in soil was maintained. Zn concentrations in spinach ranged from 412.8 to 1722 mg kg-1 d.m. and increased with growing degree of substratum pollution with this element. Over the course of the vegetation period the content of Zn in plants was generally greater. GSH content in spinach grown in both years of experiments fluctuated from 31.70 to 238 μg g-1 f.m. The biggest content of this compound in spinach was stated in the initial phase of plants growth. The plants tolerated only the first two Zn doses supplied to the substratum. Spinach growing in the objects where zinc additions to the soil equalled II and III degree of substratum pollution died shortly after germination. The plants from these objects in the initial growth phase contained significantly less GSH than spinach from the objects with two first degrees (0 and I) of substratum pollution with zinc or from the control. The content of reduced glutathione form in spinach is a good biomarker of oxidative stress caused by zinc presence in plants. Synthesis of a bigger amount of GSH conditions spinach plant resistance to over the norm zinc content in soil. The efficiency of antioxidative system in spinach is bigger in the initial phase of this plant growth.

Methyl jasmonate (MJ) is a widely occurring molecule. Since it is synthesized constitutively, its presence is substantial to plant normal growth and development. Moreover, its elevated concentration detected under abiotic and biotic stress conditions seems to be crucial to plant in reacting to adverse events and its ability to survive. Because of the sophisticated biochemical machinery inside the plant body, MJ, among other molecules, helps the plant to adopt to the surrounding environmental changes and is involved in its defense system.

W pracy przedstawiono jednolite podejście do rozwiązywalna zagadnień koncentracji naprężeń wokół karbów ostrych i zaokrąglonych. Wykorzystując metodę osobliwych równań całkowych otrzymano rozwiązanie dla rozciąganej półpłaszczyzny sprężystej zawierającej karb o wierzchołku kołowym o małym promieniu krzywizny. Przejście graniczne w rozwiązaniu numerycznym umożliwiło obliczenie współczynników intensywności naprężeń w wierzchołkach karbów ostrych o dowolnym kącie rozwarcia. Przedstawiono wzory aproksymacyjne do szacowania wartości współczynników koncentracji naprężeń w funkcji promienia krzywizny w wierzchołku karbu.
The unified approach to solve problems of stress concentration around sharp and rounded V-shaped notches m an elastic half-plane based on singular integral equation method was proposed. At first, die problem was solved for an elastic domain with V-shaped notch with rounded vertex of small radius of curvature. Then the passage to the limit, when curvature radius tends to zero, was used to obtain stress intensity factor at the vertex of sharp V-notch. The numerical results of stress intensify factors and stress concentration factors for the edge V-shaped notch in a half-plane were discussed.

Opis:

Extensive literature indicates that the effect of strengthening materials is related to their structural construction. The structure of the metallic material exhibits the greatest strengthening effect when there is a very limited movement of dislocations and their movement is completely blocked due to numerous obstacles [1, 3, 6-9, 12, 15, 16]. In this paper strain, rate and temperature dependences of yield strength of metallic materials are presented. The effect of temperature and strain rate on the value mechanical threshold stress is determined. In addition, the effect of temperature on the Kirchhoff modulus and Burgers vector is determined. The interaction of dislocations with grain boundaries causes additional stress – athermal stress causing the strengthening of the structure. The term “athermal” implies that thermal activation is unable to assist the dislocation past these obstacles. The strengthening of metallic materials is related to the dimensions of the grains, which influence the athermic stress. The calculations of mechanical threshold stress and other parameters of the structure of the material allow for easier understanding of the strengthening of the material loaded with temperature and strain rate. The largest strengthening occurs in pure metals and their alloys in the case of the total blocking of dislocation motion. This process takes place when the temperature is 0 K or at very high strain rates. The metal demonstrates the greatest effort, which is called mechanical threshold stress (MTS) [5].

An equivalent stress with periodic (in the mean-square sense) components is defined by means of the equivalence conditions based on the average strain distortion energy. Also, is formulated the fatigue "safe-life" design criterion which covers the condiŹtions of both static strength and fatigue safety and includes yield strengths and fatigue limits which : have simple physical interpretation, can be determined by uniaxial tests, are directly related to the applied loads, and can reflect material anisotropy.

Background. Tobacco use is the foremost preventable cause of death and disease in the world today and work strain might be related with nicotine dependence by its provoking effect. Objective. To assess the association between occupational stress and nicotine dependence. Material and methods. A cross sectional survey was conducted among 200 subjects visiting a satellite dental clinic of Swami Devi Dyal Hospital and Dental College, Barwala, Panchkula, India. Nicotine dependence was measured using the Fagerstrom Test for Nicotine Dependence (FTND). The extent of the stress factors experienced at work was assessed using the Effort-Reward Imbalance scale (ERI). Chi-square test and multiple logistic regression analysis were employed for statistical analysis. Confidence level and level of significance were set at 95% and 5% respectively. Results. The results of bivariate analysis revealed association of occupational stress with age, marital status, educational status, level of nicotine dependence, frequency of cigarette smoking and religious attendance. However, multivariate analysis elicited the significant association of occupational stress with only two variables, level of nicotine dependence and frequency of smoking. Conclusion. Occupational stress was found to be associated with nicotine dependence in the present study implying a need of other tranquil measures to be incorporated for the relief of work related stress.

Opis:

Wheat and maize are the main staple food crops that contribute to human food security. Their growth, however, is reduced under stresses such as salinity. The plant microbiome is associated with each plant tissue and develops a holobiont in association with the plant. Plants actively manage the configuration of their related bacterial population and its function. These microorganisms provide a broad range of benefits and advantages to the plants. The present study aimed to examine the growth improvement of wheat var. HD 2687 and maize var. PSCL-4642 under salinity at the seedling stage following inoculation of salt-tolerant plant growth-promoting rhizobacteria (PGPR) BoGl120 purified from Bougainvillea glabra. The seed germination potential with/without bacterial inoculation was examined at 50, 100, 150, and 200 mM NaCl concentrations for both crops. Compared to controls, at 50 mM NaCl concentration, the BoGl120 isolate provided the maximum radicle length in maize (32 mm) and in wheat (24.8 mm). At 100 mM NaCl concentration, however, the radicle length of wheat and maize seedlings was decreased. Inoculation of plants with the BoGl120 isolate enhanced the plumule length of seedlings at different NaCl concentrations as compared to controls. In comparison with controls, BoGl120 improved the plumule length of wheat to 32.6, 14.0, and 8 mm at 50, 100, and 150 mM NaCl concentrations, respectively. The results of the present study support the concept that PGPRs could help to increase the tolerance against saline stress in wheat and maize at the seedling stage.

Opis:

This article deals with the problem of professional burnout among correctional facilities workers (such as pedagogues, teachers, psychologists and prison officers) as being particularly vulnerable to this phenomenon. In this paper professional burnout has been dealt with twofold, i.e. as a result of dispositional as well as situational evaluation of stress. In the former case, professional burnout is connected with the way an individual functions in his/her working environment with various strategies of dealing with occupational stress. Individual features and characteristic ways of coping with stress at work have been taken into consideration. It has been found that both personal predispositions and individual approach to the assigned tasks are important predicates of burnout. Following on from this, a set of potential features that prison officers should be characterised by has been described. In the context of situational infl uence on stress, the description of a workplace plays a crucial role as it is an institution, which, very peculiar in its character, may bring about stressful situations that, in turn, may lead to burnout, no matter what individual strategies of overcoming difficult situations have been applied. The article describes situations that might infl uence the cognitive evaluation of an individual as stressful situations, it also presents features that can possibly lower the stress and those are controllability and predictability of the incident. Finally, it has been emphasised how important it is to prevent the workers particularly vulnerable to burnout from such situations as early as possible. It might be helpful to be familiar with the potential stress factors at work and to be equipped with professional diagnostic tools which will distinguish the features and the personality types exceptionally susceptible to burnout, remembering at the same time that burnout is a special phenomenon that should not be mistaken with experiencing stress at work, fatigue, alienation or depression.

Opis:

Residual stress has a great influence on the mechanical behaviour of arterial wall. Numerous research groups used the Uniform Stress Hypothesis to allow the inclusion of the effects of residual stress when computing stress distributions in the arterial wall. Nevertheless, the available methods used for this purpose are very expensive, due to their iterative nature. In this paper we present a new method for including the effects of residual stress on the computed stress distribution in the arterial wall. Methods: The new method using the Uniform Stress Hypothesis enables computing the effect of residual stress by averaging stresses across the thickness of the arterial wall. Results: Being a post-processing method for the computed stress distributions, the proposed method is computationally inexpensive and, thus, better suited for clinical applications than the previously used ones. Conclusions: The resulting stress distributions and values obtained using the proposed method based on the Uniform Stress Hypothesis are very close to the ones returned by an existing iterative method.

High pressure apparatus is widely used in industries, the design of them depends on stress distributions in their walls. Most of high pressure apparatuses are made in form of cylinders. To raise load-bearing capacity and extend operation life for high pressure apparatus, the autofrettage technology is often used. To design autofrettaged high pressure apparatus, it is necessary to study characteristics of stresses in the wall of thick-wall cylinders, including residual stresses and total stresses, etc. In this study, through investigating the characteristics of stresses of cylinders subjected to internal pressure according to the maximum distortion strain energy theory, a set of simplified equations for residual stresses and total stresses are obtained, the safe and optimum load-bearing conditions for autofrettaged cylinders are found out, which are the basis for design of autofrettaged high pressure apparatus.

Opis:

The paper presents a study on the effect of soil matric suction on the variation of leaf chlorophyll index and nitrogen concentration of canola. Results showed that chlorophyll index increases exponentially with soil matric suction, especially at the late season of canola growing time. At moderate matric suction (200 and 300 kPa soil suction heads), chlorophyll index remains nearly constant, but in drier soil (matric suction >300 kPa),chlorophyll index increases gradually with time. Despite the va-riation of the total leaf nitrogen with the soil matric suction, it is similar to the variation of the chlorophyll index, but the results showed that the chlorophyll index – nitrogen concentration curve has a de-marcated bi-modal shape. We suggest that 2.7% of nitrogen and 69.8 of the chlorophyll index value represent the upper limit of the chlorophyll meter reliability for estimation of canola nitrogen under a wide range of soil moisture levels. These results confirm that the chlorophyll meter can be used as an effective tool for rapid and non-destructive estimation of the relative chlorophyll and nitrogen content in canola leaves at a wide range of soil moisture content, except for nearly wilting coefficient or extremely high drought stress.

This paper describes the study of ventilated car disc brakes stress-strain conditions and friction under the pressure using the ANSYS environment. Such influencing factors are taken into account in the course of research as angular speed value, the pressure of the pads on the disk, the nature of the load application, convection, thermal expansion, etc. Computer modelling of the stress field and the transient thermal field in the area of contact between the pads and the disk is provided by the method of sequential thermostructural communication of the intermediate states of the brake model directly in the ANSYS Coupled Field Transient environment. Besides, the ANSYS calculations were also performed based on the primitive assembly model of two steel blocks (the discrepancy was less than 3%) to determine the identity of the theoretical knowledge about the heating of bodies as a result of the work to overcome frictional forces. Finally, a high level of calculation results convergence by analytical formulas and computer modelling was established. Since this approach justified itself, its principles were taken as a basis in the calculations of ventilated disc brakes of cars, which significantly facilitates their application, knowing the area of the active part of the disc (the rest of the boundary conditions are typical and correspond to the normal operating modes of the vehicle).

Opis:

Coiled compression springs are widely used in suspension systems of vehicles, light weight trailers, trains etc and their task is to minimize dynamic loading effect to vehicles body or frame in different road condition over many years. In these systems, springs are exposed to large number of cycles of loading and determination of their durability and reliability quantities is important. Consequently, to increase the reliability of these systems, a more accurate determination of the values of the endurance limits of springs is necessary. Usually, in many strength problems, the major components of stress are static, with less accurately alternating stresses superposed. Most failures of springs are originated with stress of alternating type. The solution of problem is accomplished due to acting shear and axial stresses in plane of cross-section of spring wire. By existing theory, when springs are loaded by non-steady loading, then to consider of unlimited number of combinations of amplitude and mean stresses, the line of failure of the material must be used. Since experimental data for the line of failure of material are usually not at hand, it is customary to make a conservative approximation, that it is a straight line. However, use this straight line may give considerable mistakes on determination of the limit range stresses. To avoid fore aft mentioned mistakes, the method of approximation of the failure curve line by the line with the properly chosen parameters for the coiled compression and tension springs is proposed in this paper. Theory to use proper parameters in approximation of failure curve and calculation example with results is given as well.

Opis:

All soldiers taking part in military actions abroad are exposed to a number of negative consequences connected with experiencing combat stress. Surviving the war and returning home where the family awaits is a great success. Unfortunately, the sad truth is that soldiers who continuously dealt with death and damage, after coming back home cannot find themselves in a different reality. The consequences of participating in a mission will be present in many areas of life. Functioning of the soldiers who participated in the mission in chronic stress causes a number of unavoidable negative consequences. All the accommodative processes can be examined both from a biological and social point of view. What is more, their schematic course can be described on a timeline. The most important is a quick diagnosis and the implementation of an adequate medical treatment. Social support is also invaluable. Otherwise, chronic stress may contribute to many diseases. The aim of the article is to analyze consequences of chronic stress-related functioning of soldiers participating in missions.
Wszyscy żołnierze biorący udział w działaniach wojennych poza granicami kraju narażeni są na szereg negatywnych konsekwencji związanych z doznawaniem stresu bojowego. Ogromnym sukcesem jest przetrwanie wojny i powrót do kraju, gdzie czeka rodzina. Niestety smutną prawdą jest, że żołnierze, którzy nieustannie obcowali ze śmiercią i zniszczeniem po powrocie do domu nie potrafią odnaleźć się w odmiennej codzienności. Problemowe stają się nawet podstawowe obowiązki codziennego życia. Konsekwencje uczestnictwa w misji zaznaczać się będą na wielu płaszczyznach życia. Funkcjonowanie żołnierzy uczestników misji w chronicznym stresie powoduje szereg nieuniknionych, zazwyczaj negatywnych konsekwencji. Wszelkie procesy przystosowawcze do stresu rozpatrywać można zarówno z psychologicznego, biologicznego, jak i społecznego punktu widzenia. Co więcej ich szablonowy przebieg można opisać w czasie. Ważnym elementem jest przede wszystkim szybka diagnoza i zastosowanie odpowiedniego leczenia. Nieocenione okazać się może również wsparcie społeczne. W przeciwnym razie chroniczny stres przyczynić się może do powstania wielu chorób. Celem artykułu jest analiza funkcjonowania w chronicznym stresie żołnierzy wyjeżdzających na misje.

Alcohol addiction is a negative social phenomenon, which causes damage to companies and individuals, is the cause of problems in marriage and threatening the healthy development of children and youth. Recovering alcoholic-woman a child psychologically unsuitable, unwanted social model provides the role of women, mothers and wives. In another work of the author, we have confirmed that alcohol may be the cause as well as the consequences of alcoholism. We also found a positive change in the personality of the abstinent survey alkoholic woman and their spiritual emotion, resocializáciou and faith in God have managed to succeed over their alcoholism. We want to point out the importance of the spiritual component, which has been acquired and developed over the years, often until after the entry into force of the negative experiences of women dependent on alcohol.

Objectives: This study was conducted to examine the psychometric properties of the French versions of the Perceived Stress Scale (PSS) and to compare the appropriateness of the three versions of this scale (14 items, 10 items, or 4 items) in a sample of workers. Materials and Methods: Five hundred and one workers were randomly selected in several occupational health care centers of the North of France during 2010. Participants completed a questionnaire including demographic variables and the PSS. The psychometric properties of this scale were analyzed: internal consistency, factorial structure, and discriminative sensibility. Results: For the PSS-14 and PSS-10, the Exploratory Factor Analysis (EFA) provided a two-factor structure, corresponding to the positively and negatively worded items. Those two factors were significantly correlated (r = 0.43 and 0.50, respectively). For the PSS-4, the EFA yielded a one-factor structure. The reliability was high for all three versions of the PSS (Cronbach’s α values ranged from 0.73 to 0.84). The results concerning the effects of age, gender, marital, parental and occupational statuses showed that the 10-item version had the best discriminative sensibility. Conclusions: The findings confirmed satisfactory psychometric properties of all the three French versions of the PSS. We recommend the use of the PSS-10 in research settings because of its good psychometric properties.

Opis:

The objective of the present article is to determine the negative changes that stress experienced by soldiers of participants in international missions may trigger in their functioning. It is assumed that these changes can be so extensive and intense that they will be able to limit the ability of soldiers to take action. Therefore, their participation in the international mission may be limited. This objective can be achieved by using methods of analysis and criticism of subject literature, as well as by induction and deduction. In the result of the carried analysis the author comes to the conclusion that stress can negatively affect the physical and psychological functioning of soldiers participating in international missions. Mission stressors can occur on the physical, cognitive, emotional, social and spiritual levels. They can trigger negative changes that are noticeable in the behaviour of soldiers. Furthermore they can also be so extensive that they can affect their ability to take combat action. The quoted research results are significant, as the description of how exactly the stress-induced negative changes in a single soldier can affect not only the safety of that individual, but also others, and thus the success of the entire mission.

Opis:

This study devised a pronunciation computer program to examine whether mobile-assisted language learning (MALL) could facilitate college students’ acquisition of English phonemes and word stress. Thirty-eight participants enrolled in the remedial English class offered at the language center of a national technological university in central Taiwan. Before the class, they were asked to read a word list. In the following six weeks, they were taught to distinguish and articulate English phonemes and to predict word stress locations using the designed computer program. They were also instructed to review the learning materials using the smart-phone version of the devised program. After the teaching session, each participant was asked again to read the same word list and fill out an assessment questionnaire. The sound analyses show that their readings of English minimal pairs and word stress placement were more accurate than their performances before the instruction. Their responses to the questionnaire indicate that both the given instruction and the designed computer program were satisfactory. In the open-ended questions, some of them said that they have built up a better understanding of phonemes and word stress, and that they would try to predict polysyllabic word stress when reading English articles. The present findings can be further applied to research on MALL-based English pronunciation acquisition.

Stress is one of the single most significant factor for many physical and psychological dilemma. Long-term exposure to stress or chronic stress can lead to serious physical and psychological problems such as headaches, fatigue, depression, anxiety, stomachache, heart problems, chest pain, asthma, hypertension, liver dysfunction, diabetes, arthritis, suppressed immune system , skin conditions, irregular ministerial cycle, infertility, accelerated aging process,and premature death. As under perennial and /or continual stress condition the body releases excessive cortisol hormone that results in aforementioned issues. Physical activity may beneficial for mental and physical body system. Under intense or endurance exercise however increase total cortisol released levels far above the moderate training modalities which can be a destructive factor for people under extreme negative stress and can make worse stress health risk conditions.Thus, caution is need to be considered for people with negative stress.Nonetheless, according to the American physical activity guideline 10 minutes moderate aerobic exercise such as walking in division of 2×10 min or 3×10 min per day that can be performed throughout the week, seems to be helpful alternative for all adult in part people with psychological negative stress.

We used the Questionnaire on Resources and Stress (QRS, designed by J. Holroyd) to assess the parental stress among families of developmentally delayed children or children with intellectual disabilities. The results of the study indicate that, comparing to mothers of children with Down syndrome and mothers of children developing well, mothers of autistic children are the ones who experience the highest level of parental stress. Potential sources of coping strategies among mothers of children that suffer from autism are associated with relatively low stress levels as a result of disharmony within the family, personal issues, the child’s health situation and financial problems.

The paper presents mathematic-statistic methods defining the influence of stress on ceramic elements’ durability of hip and knee joints endoprostheses. The tests were conducted with Finite Elements Method in the ADINA System. The obtained results state the influence of load on the values of durability and stress, that get formed in ceramic parts of joints, and help to detect and solve technical problems and thus, counteract the subsequent effects resulting from premature wear of endoprosthesis elements. The paper emphasizes necessity of discovering new materials, that will be bio-compliant and wear resistant. Although ceramic materials like Al2O3, ZrO2, are brittle and less resistant to load than metallic implants, their improving mechanical parameters (excellent tribological properties), make them becoming new standard in biomaterials for clinical use. That opens new possibilities especially for hip or knee joints alloplasty.

Analytic solutions are to indicate and define the areas where damages or premature wear of cooperating elements may occur. Analytical-experimental research states complete and thorough analysis. Accurate technical simulation of the joints of the human motor system, is difficult to conduct due to high level of complexity of human bio-bearings. All attempts to simulate the work of human joints, lead only to an approximate reflection of real human joint motion. To properly face the above problems, along with numerical analysis, there have been conducted empirical tests on the simulator of knee joint endoprosthesis.

Opis:

The study presents results of research on family adaptation pattern in situation of unemployment distress. Theoretical basis is McMaster Model of Family Functioning, modified by P. Steinhauer. The method was Family Questionaire, by M. Cierpka (Cierpka, Erevert, 1994) based on Family Assessment Measure III, by P. Steinhauer et al. (1984). Subjects was unemployed men (23) and women (22) and their families. The results suggest serious disfunctions in every family system dimensions, except affective involvement. The threat of crisis is deeper in families of unemployed men, whose self-assessment as family member is strongly connected with disfunction of whole family system.

Opis:

Background. Medical workers, especially nurses, are susceptible to numerous stressful situations, due to the great demands which are a result of the specifics of working with an ill person. The aim of the study was to identify stress factors in nursing work, without taking into account the place of employment (i.e., wards). Material and methods. The study group was made up of a sample of 102 nurses, 15 male and 87 female. The diagnostic poll method and the interview technique were used, and a designed questionnaire was used as the research tool. During statistical analysis, a non-parametric χ2 test was used (p<0.05). Additionally, the strength of the examined relationships was determined (rp). Results. Work was the main source of stress (44.1%) for the participants. Of the nurses, 39.2% often felt stressed at work, whereas emotional tension was present in 25.5% of the participants constantly. Nearly half felt burdened by everyday tasks at work, while talking about the problem (55.9%) and physical activity (37.3%), including walks (19.6%), were the most frequently used forms of fighting stress. Significant relationships were found between the level of stress and the marital status and place of residence of the participants. Conclusions. Some nurses assessed the stress that accompanied them at work as being high and over half of them felt it was an average level of stress. Stress was the most often mentioned detriment-to-health factor in the opinions of the participants.

Opis:

To study coal permeability evolution under the influence of mining actions, we conducted a sensitivity index test on permeability to determine the influence of axial and confining stresses on coal permeability. Loading and unloading tests were performed afterward, and the differences between loading and unloading paths in terms of strain and permeability were studied. A permeability evolution model was built in consideration of absorption swelling and effective stress during modeling. An effective stress calculation model was also built using axial and confining stresses. The calculation results of the two models were compared with experimental data. Results showed that permeability were more sensitive to confining stress than axial stress, and effective stress placed a large weight on confining stress. Large axial and radial deformations at peak strength were observed during unloading. In the unloading phase, the permeability of coal began to increase, and the increment was enhanced by large initial axial stress when confining stress was loaded. permeability sensitivity to axial and confining stresses were used to explain these permeability changes. The calculation results of the models fitted the experimental data well. Therefore, the proposed models can be used to calculate effective stress on the basis of axial and confining stresses and describe permeability change in coal under the influence of mining actions.

Biofertilizers are the special formulation of specific beneficial microorganisms that promote the growth of plant crops by converting the unavailable form of nutrients into available form. Here, the effect of heavy metal stress on antioxidant enzymes were studied in Clitoria ternatea L. leaves. Clitoria ternatea L. plant was grown for 30 days and the heavy metal mercuric chloride was sprayed after 10 days from the date of planting. Effect of mercuric chloride was observed in treated plants. The selected plant Clitoria ternatea L. was grown under mercuric chloride treatment in a specified concentration 1 μg/10 ml. The control plant maintained without the treatment of mercuric chloride. Antioxidant effect of mercuric chloride was measured under controlled and treated conditions. The selected plant Clitoria ternatea L. was grown under mercuric chloride in treatment. Further it increases H2O2 content and the antioxidant enzyme activities such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) were observed in mercuric chloride treated plants when compared with control. Here mercuric chloride was accumulated more in matured leaves. The results are discussed with the literature.

Analizowano jak warunki obciążenia powierzchni gleby, tj. siła, nacisk jednostkowy i współczynnik koncentracji naprężeń wpływają na zasięg w glebie izobar naprężeń dopuszczalnych 30 i 50 kPa. Określono zasięg izobar jak i powierzchnię objętą tymi izobarami. Stwierdzono, że wraz z wzrostem nacisków powierzchniowych przy stałej sile zasięg izobar w głąb wzrastał, lecz ich szerokość malała. Występowało także przesuwanie się w dół punktu największej szerokości izobary.
It was analysed how the conditions of soil surface load i.e. force, unit pressure and stress concentration coefficient, influence the range of the isobars of admissible stress of 30 and 50 kPa. The range of stress as well as the area of soil affected by these stresses was determined. It was found that the isobars penetrated deeper into soil but their width was getting smaller along with growing surface unit pressure at constant force. The point of the greatest width of the isobar shifted down.

Opis:

In this review we summarize stress factors that affect the lactic acid bacteria (LAB) and cause different molecular stress responses. LAB belong to a group of bacteria that is very widespread in food and beverages. They are present, and desired, in fermented products like yogurts, cheese, vegetables, meat or wine. In most of them, LAB are providing positive sensory and nutritive features. However, as harmless and desired microbes in one product, LAB can cause spoilage and a bad taste of others, especially in juices and beverages. LAB are resistant to many stress factors which allows them to survive in harsh environments. The most common stress factors they have to deal with are: heat, cold, acidity, NaCl and high hydrostatic pressure (HHP). Their ability to survive depends on their skills to cope with stress factors. Under stress conditions, LAB activate mechanisms that allow them to adjust to the new conditions, which can influence their viability and technological properties. This ability to adapt to different stress conditions may come from the cross-protection systems they have, as resistance to one factor may help them to deal with the other stress effectors. LAB are highly valuable for the food industry and that is why it is important to understand their stress response mechanisms.

Opis:

Jedną z najpoważniejszych chorób psychicznych jest schizofrenia, na którą choruje 1% populacji. Choroba powoduje znaczące utrudnienie osiągnięcia niezależności w życiu dorosłym. Jej przyczyny nie są w pełni znane. Celem artykułu jest przybliżenie roli stresu w wystąpieniu choroby w oparciu o model teoretyczny podatność - stres. Badania potwierdzają istotną rolę neurobiologicznych procesów psychopatologicznych sprzyjających psychozie. Obniżony poziom kompetencji radzenia sobie ze stresem jest konsekwencją neurobiologicznych i psychologicznych nieprawidłowości powstałych na długo przed pierwszym epizodem psychotycznym. Rozwój metod radzenia sobie ze stresem może istotnie przyczynić się do poprawy funkcjonowania społecznego, zmniejszenia częstości zaostrzeń w przebiegu choroby, opóźnienia jej wystąpienia, a nawet zmniejszenia ryzyka zachorowania.
Schizophrenia is one of the most severe mental disorders, which affects 1% of the population. A large group of patients have difficulties in achieving financial independence and start a family because of burdenning course of the illness. The etiopathogenesis of schizophrenia is not fully discovered. The aim of this article is to present the role of stress in the onset of schizophrenia based on vulnerability-stress models. Many researches confirm neurobiological and psychological factors in psychopathological processes leading to psychotic symptoms. The decreased level of coping skills is a consequence of neurobiological and psychological abnormalities developed long before the first episode of psychosis. The development of stress management skills can significantly improve social functioning, reduce exacerbations in the course of illness, delay the onset, and even reduce its risk.

Opis:

Dla wielu ludzi praca zawodowa jest źródłem silnych emocji. Złość, gniew, lęk, strach lub silne zdenerwowanie dezorganizują postrzeganie i zakłócają myślenie oraz wykonywanie czynności. Pośrednio wpływają na popełnianie wielu różnych błędów, w tym także wypadkowych. Dlatego też ważnym elementem jest rozpoznawanie i eliminowanie w zakładach pracy przyczyn stresu zawodowego oraz uodparnianie ludzi na działanie stresu. W artykule przedstawiono problematykę związaną ze stresem zawodowym wśród pracowników kopalń węgla kamiennego. Omówiono ogólne pojęcie stresu oraz stresu zawodowego, jak również stresorów, czyli bodźców, które wywołują reakcję organizmu. Przedstawiono skutki zdrowotne związane ze stresem zawodowym oraz wpływ stresu na funkcjonowanie przedsiębiorstwa. W artykule przedstawiono propozycję badań ankietowych odnośnie stresu zawodowego wśród pracowników górnictwa. Zawarta w nim ankieta złożona jest z trzech części ujmujących następujące obszary problemowe: właściwości fizyczne środowiska pracy, czynniki społeczne środowiska pracy oraz czynniki stresogenne powodowane złą organizacją pracy. Ankieta ma formę otwartą i jest anonimowa. Respondenci mogą udzielać jednej lub kilku odpowiedzi spośród podanych, bądź mogą sami wyrazić własną opinię. Badania obejmą reprezentatywną, losowo wybraną grupę ludzi zatrudnionych na stanowiskach dołowych i przeprowadzane będą na okresowych szkoleniach bhp. Dodatkowo w badaniach uwzględnione będą informacje o wieku, stażu pracy (w tym, w samym górnictwie) oraz wykształceniu zawodowym pracowników. Badania ankietowe odnośnie stresu zawodowego umożliwią podjęcie właściwych działań profilaktycznych w celu zidentyfikowania i wyeliminowania występujących w zakładzie górniczym stresorów zawodowych. Pozwolą dostrzec, iż stres jest problemem dotyczącym zarówno poszczególnych pracowników jak i całego zakładu pracy. Pomogą pracodawcy w projektowaniu odpowiednich warunków pracy o ograniczonym potencjale wywoływania stresu oraz dadzą możliwość wyposażenia pracowników w wiedzę i umiejętności do radzenia sobie za stresem.
For many people, professional work is a source of strong emotions. Anger, wrath, anxiety, fear or nervousness strong perception disorganize and disrupt thinking and execution activities. Indirectly affect the perpetration of a variety of errors, including the accident. Therefore, an important element is the identification and elimination in the workplace causes of occupational stress and immunization of humans under stress. The article presents the problems associated with occupational stress among employees of coal mines. Describes the general concept of stress and occupational stress, as well as stressors or stimuli that trigger the body's response. Presents the health effects associated with occupational stress and the effect of stress on the functioning of the company. The article presents a proposal for the survey regarding the occupational stress among employees of mining. Included in the survey it consists of three parts endearing following problem areas: physical environment, social factors working environment and stress factors caused by poor work organization. The survey takes the form of an open and anonymous. Respondents may provide one or more of the answers given, or they can express their opinion. Research will include a representative, randomly selected group of people employed in positions of underground and will be carried out on a periodic safety training. In addition, studies will be included information on age, length of service (including in the mining industry) and education unions. Surveys regarding occupational stress make it possible to take appropriate preventive measures in order to identify and eliminate occurring in the mining industry job stressors. Will see that stress is a problem for both individual employees and the entire company. Employers will help in the design of appropriate working conditions with limited potential to cause stress and give possibility to equip employees with the knowledge and skills to handle the stress.
