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 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. At the same time, the value of nonflatness is inversely proportional to the plate thickness.

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:
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.

Every individual who works in caring professions must demonstrate a high level of personal resilien- ce, bravery, mental and physical endurance, and the ability to cope with work stress continuously and effectively. 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.

Purpose: Stress is inseparable part of life. It is an occurrence which influes on individual life, both on health and family and social aspects. 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:
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.

Opis:
Article examines the occurrence of professional stress among academic teachers (postgraduate students), doctors and policemen particularly exposed to intensive in uence of stressful impulses for social character of the functions they perform. Basing on the literature of object, author enriches the analysis with his own ndings. In rst instance he de nes the notion of stressors and then he tries to nd and make them up in the form of specific threats, adequate for each of the above mentioned professional groups. His analysis is extended by the aspect of professional transformations taking into consideration their social-cultural conditions. Thanks to it the author shows the existence of relationship not only between the age of respondents and susceptibility on stress but he underlines as well how important place in human’s needs hierarchy takes the professional job. Frustration, fear, tension and anxiety destructively in uence the psychical form of an individual e ecting in negative consequence de ned by the hereby article as a professional burnout.

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.

Opis:
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.
