Opis:
Visualization models have accompanied the designing of buildings and structures since ancient times. Their purpose has been to give the investor an idea of what a building and different solutions applied in it would look like. To this end, models of different materials were built. But as technology progresses, it became possible to create new visualization tools and methods. Initially, drawing boards were replaced by computer programs referred to as computer-aided design (CAD), which supported the design process. They facilitated the creation of sets of lines and simple planes. With time, the designers increasingly felt the need to shape not just rectilinear but also curvilinear objects by means of computers. This is when parametrization came in handy. Parameters constitute a set of variables which can be shaped while keeping the interdependencies between them. Parametric modelling gave rise to the building information modelling (BIM). Now, a virtual model can not only be shaped in a digital environment but also enriched with different information. This way it not only has a geometry but also a structure. It was also assigned other data allowing identification of the material or technology used to erect a building or a structure. Parametrized elements of a building provide information about their number, purchase cost or physical properties. Parameters allow making quick and seamless corrections. Thanks to the application of advanced technologies, designers from different areas can keep track of these changes. Following accepting them, one can easily generate a complete set of technical documents and use them in a digital or paper format at a construction site. Parametrization makes it possible to erect buildings and structures that would have been impossible to design in the past. Today, every designer either already uses parametric modelling or will start using it sooner or later.

Opis:
A number of studies indicate that proper education for sustainable development both in formal and informal sphere has been neglected and the implementation of the sustainable development principles is definitely insufficient and ineffective. The presence of the sustainable development contents in the education system results mainly from the interdisciplinary training pathway „Environmental education” realised in recent years. It is focused mainly on the environment and nature issues while the social and economic issues are poorly addressed if at all. A realistic implementation the sustainable development principles into practice can take place only through intensive training and information efforts in the sector of formal and informal education. The effectiveness of these efforts will be high on condition that they are subject to careful planning at each stage of their realisation.

It is expected that during 1980 – 2020 the population of older people worldwide will increase by 240%. The objective of the study was to review strategies undertaken in various countries in association with the ageing of society. This analysis may be used for the selection of actions, which are necessary for the construction and performance of social and health policy in Poland. A method of choice was an analysis of academic literature. The WHO specified health promotion as the most important goal of the policy for seniors. Individual countries adopt many varied strategies of action. In Poland, the introduction of nursing insurance and development of geriatric medicine are primarily proposed. In Japan, the emphasis is placed on enabling the elderly the longest occupational activity possible, and the development of primary health care. For the Swedish, the priority is guaranteed support for family caregivers, while in the United States - an increase in the accessibility of environmental care. There are many strategies developed on an international forum whose purpose is to provide care for the growing number of seniors. The strategies adopted by individual countries are much varied. The basic postulates are a development of geriatric medicine and integration of the systems of health services and social security. The literature lacks reports on the effectiveness of the implemented strategies.

Opis:
Introduction and objective. The biochemical and anthropometric consequences of metabolic disorders exert an enormous effect on the functioning of people worldwide. The aim of this study is to assess relationships between biochemical and anthropometric parameters associated with metabolic syndrome, and the presence of the PPAR-γ rs1801282, the FTO rs9939609, and the MC4R rs17782313 polymorphisms in women aged 45–60. Materials and method. The study included 425 women, aged 45–59 years, from the general population of the West Pomeranian Province in north-west Poland. The research procedure involved a structured interview, anthropometric and blood pressure measurements, biochemical analysis of serum, and genetic analysis. Results. The carriers of the A/A genotype of the FTO polymorphism had higher LDL levels than their counterparts with the T/T genotype (p=0.01). The carriers of the T/T genotype of the MC4R polymorphism had lower non-HDL levels than those with the C/C and C/T genotypes (p=0.019). Weight was related to the C/C and the C/G + G/G genotypes of the PPAR-γ gene polymorphism (p=0.046). The model of inheritance for the MC4R polymorphism had a significant effect on TG (p=0.039) and non-HDL (p=0.05) levels. Conclusions. The genotypes analyzed in the study had only a slight direct effect on the biochemical and anthropometric abnormalities typical of metabolic disorders. Nonetheless, the risk alleles (A allele of the FTO rs9939609 and the C allele of the MC4R rs17782313) were found to be related to lipid metabolism disorders in 45–60-year-old women.

Introduction: Proximal femoral fractures are the major cause of hospitalization due to an injury among advanced age patients. Purpose: To analyse causes of femoral neck fractures. Materials and methods: The research material included medical documentation of 203 patients with femoral neck fractures. A research method employed in this study was an analysis of the documentation. A statistical analysis was performed using the chi-square test for independence. Results: The majority of women and men sustained an injury at home or on the way (62.5% and 46.2% respectively). Patients who had an injury at work were largely men. Most injuries were related to a disease. It has been observed that women considerably more often than men mentioned slipping as the cause of an injury (21.3% and 6.9% respectively). Men, on the other hand, more often than women incurred injuries as a result of falls (19.4% and 9. 5% respectively). The structure of an injury was similar irrespective of whether patients were diagnosed as having such diseases as diabetes, cataract and osteoporosis or not. Conclusions: There is a relationship between gender and the circumstances of an injury. Women more often sustain an injury at home, and men – at work. The circumstances and causes of injuries are not significantly related to diseases such as diabetes, cataract and osteoporosis.

Opis:
Changing market preferences regarding expectations in terms of the functionality, properties, and appearance of a finished product place excessive demands on manufacturers. The 6xxx-series alloys are the most commonly used in extrusion, and they have broad applications (e.g., the construction, electronics, automotive, and shipbuilding industries). The development of deformation technology at the design stage reaps unquestionable benefits when planning the production process. Under real conditions, the extrusion of hollow profiles requires the use of pocket dies, whose proper design is a complex process. This paper presents the results of preliminary numerical investigations of the extrusion process of structural panels from the 6005A aluminum alloy intended for the construction of transport car bodies. The influence of selected parameters of the extrusion process on the temperature distribution was analyzed in the material. The calculations were made using FEM for a three-dimensional deformation state, taking into account the thermal phenomena occurring during the applied deformation scheme in the extrusion process carried out in a flat die.
Zmieniające się preferencje rynku dotyczące oczekiwań w zakresie funkcjonalności, własności i wyglądu wyrobu gotowego stawiają przed wytwórcami wysokie wymagania. Stopy serii 6xxx należą do grupy stopów aluminium zawierających magnez i krzem. Mają bardzo szerokie zastosowanie w budownictwie, elektronice oraz przemyśle: samochodowym górniczym, chemicznym, spożywczym i stoczniowym. Opracowanie technologii odkształcania na etapie projektowania daje niekwestionowane korzyści podczas planowania procesu produkcyjnego. Proces wyciskania profili wymaga w rzeczywistych warunkach zastosowania matryc komorowych, których właściwe zaprojektowanie jest procesem złożonym. Zastosowanie nowoczesnych narzędzi informatycznych pozwala na wieloaspektową analizę zmian zachodzących podczas procesu wytwarzania wyrobu gotowego. W artykule przedstawiono wyniki wstępnych badań numerycznych procesu wyciskania współbieżnego paneli konstrukcyjnych z wybranego stopu aluminium serii 6xxx, które mogą znaleźć zastosowanie jako elementy konstrukcyjne nadwozi samochodów transportowych. Analizowano wpływ wybranych parametrów procesu wyciskania na rozkład temperatury w odkształcanym wyrobie. Obliczenia wykonano przy użyciu MES dla trójwymiarowego stanu odkształcenia, uwzględniając zjawiska termiczne występujące podczas zastosowanego schematu odkształcenia w procesie wyciskania prowadzonym w matrycy płaskiej.

Introduction. To-date, the influence of heavy metals such as Pb or Cd on mental functioning, and especially on the occurrence of depressive and anxiety-related disorders, has not been well understood. Objectives. 1) Assessment of Pb and Cd levels in whole blood of postmenopausal women. 2) Assessment of the severity of anxiety and depressive symptoms depending on Pb and Cd levels in whole blood of postmenopausal women. Materials and method. The survey-based study involved 198 healthy postmenopausal women from West Pomeranian province in Poland. It was performed using the Primary Care Evaluation of Mental Disorders (PRIME-MD), Beck’s Depression Inventory (BDI), and the State-Trait Anxiety Inventory (STAI). The second part of the study was based on biochemical analysis of the levels of heavy metals (Pb, Cd). Results. The mean level of Pb was 19.85 ± 8.99 μg/l and Cd 0.87±0.98 μg/l; these levels were within normal ranges. Analysis of the mean levels of Pb and Cd in whole blood of postmenopausal women in relation to the severity of depressive symptoms did not reveal statistically significant differences. Correlation analysis demonstrated a statistically significant (p<0.05) negative correlation (-0.22) between the level of Pb and the severity of anxiety as a state. Correlations between the levels of Pb and Cd and the severity of anxiety as a trait were not statistically significant. Conclusions. The mean Pb and Cd levels in whole blood of healthy postmenopausal women did not exceed acceptable limits. The study did not confirm a relationship between the levels of selected heavy metals and the severity of anxiety and depressive symptoms in healthy women. However, there was a relationship between the level of Pb and the severity of anxiety as a state.

Opis:
Health behaviours are actions taken by a person in the field of health. Risky behaviours are those that pose a threat to health. Bioelements are essential for the proper functioning of every organism. Their trace amounts are necessary for life and health. The aim of this study was to determine the relationship between health behaviours and the levels of bioelements in the blood serum of secondary school students. This survey-based study was carried out on a sample of 376 secondary school students aged 13-16 years. It was performed using the HBSC questionnaire (Health Behaviour In School-aged Children: A WHO Collaborative Cross-national Study). Next, cubital vein blood was collected for laboratory tests, and the levels of bioelements (Mg, Ca, Cu, Fe, Zn) in blood serum were determined. The analysis of the research material did not demonstrate substantial differences in the mean serum levels of Ca, Mg, Zn, Cu, Fe between smokers and non-smokers, alcohol consumers and non-consumers, drug users and non-users. There were no statistically significant correlations between the levels of bioelements and the frequency of drinking beer and vodka (p>0.05). A statistically significant correlation was observed between Cu levels and drinking wine (p≤0.05). Subjects showing aggressive behaviours (getting into scuffles) had lower Mg and Zn levels than other secondary school students. There were weak but statistically significant correlations between Cu levels and the frequency of wine consumption, and between serum Zn levels and smoking marijuana among the subjects.

The aim of this paper was to test currently available on the market products for sealing anodic oxide coatings as well as to test the use of other alternative substances improving the sealing process. The ability to seal in 10 different solutions and the quality of the seal has been tested. The influence of the applied preparations on corrosion resistance and resistance to strongly alkaline environment was also investigated. Based on the results obtained, satisfactory results were archived for the sample sealed in a IMN-OML (Institute of Non-Ferrous Metals in Gliwice, Light Metals Division) solution sealant and in solution of nickel acetate in a medium-temperature process. Sealing by means of nickel acetate solutions is economically justified, and its use allows the process temperature to be lowered. When it comes to resistance to alkalis, samples sealed in IMN-OML sealant are the best. Commercial solutions have also achieved positive results in all tests.

Introduction and objective: The developing brain of a child is extremely prone to damage resulting from exposure to harmful environmental factors, e.g. heavy metals. Intoxication of children’s organisms with lead and cadmium affects their intellectual development. Even a relatively small amount of this metal in children’s blood can lead to developmental dysfunctions. The aim of this study was to analyse the correlation between blood lead and cadmium levels in children with behaviour disorders and their functioning in the home. Material and methods: This survey-based study was conducted among 78 families with children diagnosed as having behaviour disorders. It was performed using the ADHD-Rating Scale-IV. To determine lead and cadmium levels the laboratory procedure was based on Stoppler and Brandt’s method. Results: The mean blood lead level was 19.71 μg/l and the mean blood cadmium level was 0.215μg/l. Higher blood lead levels in children correlates positively with incidences of hyperactive and impulsive behaviour in the home, as assessed by parents (p=0.048). Statistically significant effects of cadmium on children’s behaviour were not noticed. Conclusions: The effect of lead on the developing organism of a child has such behavioural consequences as attention disorders, hyperactivity and impulsive behaviour which, in turn, may interfere with children’s functioning in the home. A negative effect of cadmium on the functioning of children with behaviour disorders in the home was not proved.

Introduction and objective: The level of trace elements is extremely important for the maintenance of normal functioning of the human body. The risk of disturbance of their balance increases especially dynamically during the period of menopause. The objective of the study was the effect of MHT on the levels of bioelements (Mg and Zn) in blood plasma, and toxic metals (Pb and Cd) in the whole blood in postmenopausal women. Materials and methods: The study covered 323 women at postmenopausal age from the population of the West Pomeranian Region, in whom the levels of Mg, Zn, Pb and Cd were determined. The women were divided into two groups: study and control. The study group were 152 women who used menopausal hormone therapy (MHT). The control group were 171 women who did not use MHT, and had had their final menstrual period at least one year prior to inclusion in the study. The mean age of the women examined was 56±5. Results: Significantly higher levels of the bioelements Mg, Zn were observed in women who used MHT, compared to the control group (p<0.05). The concentration of Pb in whole blood was significantly lower in the study than the control group: 16.09±7.33 μg/l and 20.18±9.01 μg/l, respectively. An elevated level of Cd in whole blood was found in both groups of women: 0.9±1.03 μg/l and 0.8±1.1 μg/l, respectively. It was noted that women who used MHT more frequently declared the presence of climacteric symptoms (p<0.05). Conclusions: 1) Higher levels of Mg and Zn were found in blood plasma of women who used MHT. 2) The mean concentration of Cd in the blood of women in both groups was similar. 3) In women who use MHT the level of Pb in whole blood was lower, compared to the rest of the women.
