Résumé :

Darbe siekta nustatyti, ar psichologinis-socialinis stresas siejasi su gyvenimo stiliaus ypatumais: priklausomybes sukeliančių medžiagų (alkoholio, tabako, narkotikų) vartojimo kiekiu bei polinkiu tai keisti; su mityba ir fiziniu aktyvumu bei noru keisti gyvenimo stiliaus ypatumus sveikatingumo linkme.Tyrimas atliktas naudojantis sveikatos apklausos anketa. Tyrimo rezultatai pateikiami naudojantis 18-22 metų amžiaus tirtų vaikinų 616 anketų.Nustatyta, kad: 1. Jaunuoliai, kuriems būdingas aukštas psichologinio-socialinio streso lygis, vartoja daugiau priklausomybę sukeliančių medžiagų (tabako, alkoholio, narkotikų), nei tie jaunuoliai, kuriems būdingas žemas psichologinio-socialinio streso lygis. 2. Aukšto psichologinio-socialinio streso lygio jaunuoliai labiau linkę nekeisti priklausomybę sukeliančių medžiagų vartojimo nei žemo psichologinio-socialinio streso lygio jaunuoliai. 3. Aukštas psichologinis-socialinis stresas yra susijęs su nesveikesniu gyvenimo stiliumi (mažesniu fiziniu aktyvumu, didesniu druskos vartojimu). THE LINK BETWEEN PSYCHOLOGICAL-SOCIAL STRESS AND LIFE STYLE Ieva Šidlauskaitė SummaryThe purposes of this work was to state the connection between psychological-social stress (PS stress) and life style's features, such as: nicotine use; alcohol use; drugs use; nutrition and physical activity. To state the connection between psychological-social stress level and quantity of nicotine, alcohol, drugs use; tendency to change habits in the direction of healthier life style. Research has been carried according to health questionnaire (translated by A. Gostautas, 2000). For data analysis we used results from common research with 616 youngsters (form 18 till 22 years).Conclusions are following:• Youngsters with higher PS stress level use more cigarettes, alcohol and drugs comparing with youngsters with lover PS stress level.• Youngsters with higher PS stress level are liable not to change using of nicotine, alcohol and drugs, comparing with youngsters with lover PS stress level.• Higher PS stress level is related with unhealthier life style.

Résumé :

Currently, the International Health Organizations consider stress a morbidity and should be treated as a public health issue, even more so as a result of the health pandemic experienced. The university student was no stranger to this, suffering the so-called academic stress due to both academic and social factors. To determine the level of this, the SISCO university stress inventory was used, whose purpose was to identify attributes of stress that usually follow undergraduate and graduate students in the course of their university education. It consists of 30 items divided into three dimensions: stressful situations, symptoms (physical, psychological and behavioral reactions) and coping strategies. The results indicated that this inventory has good internal consistency in the total scale and in its dimensions. In terms of validity, the AFE and AFC proved that there are three factors considered in the theoretical model: symptoms, stressors and coping strategies, and the confirmatory analysis indicates an adequate fit for the academic stress model.

Résumé :

Purpose: This article seeks to establish whether there is a relationship between the amount of sleep managers have per night and their behaviour when in stressful situations, with particular reference to their choice of coping strategy. Design/methodology/approach: In order to establish the relationship between managers’ sleep duration and their preferred styles of coping with stress, two specific research tools were employed: a Polish adaptation of the Coping Inventory for Stressful Situations (CISS) and the author’s own questionnaire assessing respondents’ daily hours of sleep. Findings: The research showed that as a variable, sleep deficit is not sufficient to explain the behaviour of managers in situations of emotional stress. However, when treated as an independent variable, sleep duration can be used to identify certain interesting behavioural aspects of managers in their professional environment. Research limitations/implications: It is advisable to extend the research to include a larger research group and to distinguish other variables specific to the functioning of people in managerial positions. Practical implications: The lack of any correlation between the extent of sleep deprivation and behaviours aimed at reducing stress may indicate that these behaviours stem more from specific individual factors (e.g. gender or age) and environmental conditions rather than sleep duration. Identifying these conditions and understanding how they can be modified may help to shape the well-being of managers and their employees. Social implications: If organisations factored sleep duration into their work/health equation, this would help direct their efforts towards ensuring the well-being of their managers, which would lead to increased efficiency and performance. Originality/value: Sleep duration does not appear to be a variable that sufficiently explains the coping strategies employed by managers, as these are more influenced by age and gender, for example. The research showed that the group of managers analysed here did not meet the recommended standards of eight hours sleep a day, with sleep duration being heavily dependent on the respondents’ age.

Résumé :

The main question of this paper is the stress-strain state prediction of the vertical shaft’s combined lining located at the interface of two layers of dolomite and salt. The study predicts geomechanical processes at the contact of the dolomite layer and the salt layer in the vicinity of the vertical shaft’s expanded section, taking into account the operating life of a vertical shaft is equal to 50 years. The results combined lining’s stress-strain state, represented as a four – layer medium, where the external layer is concrete, and the three inner layers are used to account for the heterogeneity of cast-iron tubing and are compared with the results received when taking into account the pipe structure. The solution of the problem was carried out in a three-dimensional statement. The calculation of the tubing lining, considering its actual geometry, will increase the accuracy of the forecast of the stress state of the lining, which in turn will favourably affect the justification of its parameters.

Résumé :

Cortisol, which is produced in the adrenal glands, is an endogenous glucocorticoid hormone that delivers its hormonal message to cells by acting on glucocorticoid receptors. It is one of the main stress hormones responsible for stress responses in animals and humans, and its overproduction is characteristic of certain diseases. While acute stress disorder can be evaluated by means of measuring the cortisol concentration in blood and urine, chronic stress disorder can be detected by monitoring the cortisol concentration in fur or hair. Hair collection is simple, inexpensive and non-invasive, and can be performed easily and rapidly; thus, it appears to be a suitable method for determining the level of stress in dogs from shelters, abused dogs or dogs involved in different types of animal interactions. Since it is a relatively new method, monitoring cortisol in hair or fur requires further research in order to definitively prove its efficacy, and possibly to determine reference range values for different breeds of dogs.

Résumé :

This paper analyzes the effect of workplace stress on employee productivity in the service industry with reference to bankers. The study was carried out to identify the job stress of Nigerian bankers as it will be of interest to the management to evaluate their staff performance. The study used survey design with a sample size of 400 working staff from select banks in Benin City, Edo State; this was premised on the purposive sampling method. The study adopts primary data with the aid of questionnaire, which was administered to respondents to collect data. The data collected were analyzed using regression analysis. The result from the regression analysis indicated that employee workload, role ambiguity, and role conflict were statistically significant with a value of P &gt; 0.05. The value of the Adjusted R2 of 64% reveals that the variability observed in the target variable is explained by the regression model. The study made recommendations that will enhance employee productivity in the banking industry in Nigeria.

Résumé :

An association between yield components and their direct and indirect influence on the grain yield of wheat were investigated. 24 breeding lines were tested in a randomized complete block experiment design with three replications. According to the results the phenotypic correlation among the traits and their path coefficient were estimated. Positive significant correlation coefficients were obtained for association between survival rate treatment I (0.35*) and III (0.34*), leaf venation (0.51*), stomatal frequency (0.39*), osmotic pressure (0.30*), flag leaf area (0.85*), number of tillers per plant (0.70*) with grain yield per plant at both phenotypic and genotypic levels. A negatively significant correlation between hygrophilic colloids (–0.15*) and epidermal cell size (–0.22*) with grain yield per plant was obtained at phenotypic and genotypic levels. Path coefficients were also computed to estimate the contribution of character to the yield. Path coefficient analysis revealed that flag leaf area (1.34), root/shoot ratio (0.51) and survival rate II (0.56) had the highest positive direct effects on grain yield, while hygrophilic colloids (–0.24) and osmotic pressure (–0.07) had a negative direct effect on grain yield. The results thus obtained suggested that flag leaf area is an important component of yield and hence needs a special attention in selection strategies.

Résumé :

Improvement in leaf hydraulics is directly related to the improvement of plant tolerance to drought stress. Therefore, a field and pot experiment was carried out to determine the type of genetic variability and selection of parental types on the basis of combining ability for leaf hydraulics. Genotypes showed similar performance in both experiments; higher values were shown by drought tolerant genotypes in all traits except for osmotic potential, which drought tolerant genotypes maintained lower. Osmotic adjustment in pot experiment showed the highest magnitude of additive type of genetic variability. Female showed a higher and significant contribution of general combining ability effects as compared to male; it suggests that within genotypes female rather than male mostly contribute for additive genes. AMES-10103 showed the highest general combining ability effects for traits such as turgor pressure and osmotic adjustment.

Résumé :

Joints are among the most widespread geologic structures as they are found in most each exposure of rock. They differ greatly in appearance, dimensions, and arrangement, besides they occur in quite different tectonic environments. This study is important because joints provide evidence on what kind of stress produced them (history of deformation) and also because they change the characteristics of the rocks in which they occur. The Measured data of joints from the studied area which are located in the high folded zone – Northeast of Iraq, were classified according to their relationship with the tectonic axes by projecting them stereographically using Schmidt net in GEOrient ver.9.5.0 software. The joint systems revealed the orientation of the major stress field that caused the area deformation. Two dominant joint systems were found in most stations of the studied area, which are hko>a (first place) and hko>b (second place). The main stress field direction from the joint’s classification is North East – South West which coincides with the opening of the red sea and the collision between Arabian and Iranian tectonic plates. The North West direction (which comes in the second place) it might be due to the rotational movement (counterclockwise) of the Arabian plate in addition to the effect of local stress in the area.
