Objectives The paper analyses the impact of socio-demographic characteristics of the employees in conditions of uncertainty in the organizations. Material and Methods The study was conducted on a sample of 210 employees using the Mental Health Inventory – 38 (MHI-38), Satisfaction with life scale (SWLS), and the Center for Epidemiological Studies – Depression (CES-D). Results The results showed that female respondents had significantly higher scores on ANX (t = 2,278, p < 0.05), while male employees had higher scores on life satisfaction (t = 2.103, p < 0.05). Older employees have a higher tendency for loss of emotional-behavioral control (F = 4.427, p < 0.05). Respondents who have satisfying living standards have also higher scores on SWLS (t = 2.257, p < 0.05). Respondents who have dissatisfying living standard have higher scores on generally positive affect (t = 3.152, p < 0.01), life satisfaction (t = 3.571, p < 0.01), psychological distress (t = 2.929, p < 0.01) and loss of emotional- behavioral control (t = 2.361, p < 0.05). Employees with different levels of educational background have similar tendencies in life satisfaction, mental health, and depressive symptoms (p > 0.05). Conclusions The study showed that the specific socio-demographic profile of the employees is related to higher levels of mental health issues. Specifically, the mental health of female and older employees have been especially affected and disturbed by uncertain conditions. The results can be potentially used both in the terms of designing activities that support the mental health of the population, as well as in relation to the mental health of employees.

Opis:
In this paper, the product of three random variables (RVs) will be considered. Distribution of the product of independent random variables is very important in many applied problems, including wireless relay telecommunication systems. A few of such products of three random variables are observed in this work: the level crossing rate (LCR) of the product of a Nakagami-m random variable, a Rician random variable and a Rayleigh random variable, and of the products of two Rician RVs and one Nakagami-m RV is calculated in closed forms and presented graphically. The LCR formula may be later used for derivation of average fade duration (AFD) of a wireless relay communication radio system with three sections, working in the multipath fading channel. The impact of fading parameters and multipath fading power on the LCR is analyzed based on the graphs presented.

ABSTRACT Introduction. Considering that small number of drugs are completely safe for use during pregnancy, right choice and adequate risk assessment is extremely important. Objective. The aim of this study was to analyze factors associated with estimate of high teratogenic risk (as judged by clinical pharmacologist) in pregnant females who were prescribed anti-infective drugs or mild analgesics. Methods. A cross-sectional study included 284 pregnant women who came for an advice about teratogenic risk to clinical pharmacologist in Clinical Centre Kragujevac, Serbia during the period from 1997 to 2012. All of included pregnant women were prescribed mild analgesics and/or anti-infective drugs during the first 3 months of pregnancy. The data were collected from patient files and by phone interviews. Results. Clinical pharmacologists estimated the risk of teratogenicity as “high” in pregnant females who were using tetracyclines or propionic acid derivatives. Disorders of development reported by mothers during phone interviews were associated with cephalosporin use during first 3 months of pregnancy, while miscarriages or abortions happened more often in women who used a tetracycline. Conclusions. Estimate of risk from congenital anomalies after use of drugs during pregnancy, which make clinical pharmacologists as part of their routine healthcare services, depends on amount of published data about previous experiences with specific drugs during the first 3 months of pregnancy. Key Words: pregnancy; drugs; risk of teratogenicity; risk estimate

Opis:
There is growing interest in the activity of sulfur-containing compounds on redox balance in physiological and pathological conditions, considering that some of these compounds have not only antioxidative but also pro-oxidative activities. Aim of this study was to assess possible differences in the effects of various sulfur-containing compounds on redox balance of cardiovascular system in its physiological state and in the early onset of hyperhomocysteinemia. This experimental study divided Wistar albino rats into two groups: saline-treated (control) and DL-homocysteine-treated (experimental group). Rats from experimental group were subjected to subchronic subcutaneous administration of DL-homocysteine at dose of 0.45 μmol/g body weight twice a day for 2 weeks. At the end of this period, rats were sacrificed, and blood samples were collected to be analysed for homocysteine concentration and systemic oxidative stress. Isolated rat hearts were excised and attached to the Langendorff apparatus. To assess the effects of acute administration of L-methionine, L-cysteine, N-acetylcysteine, and sodium hydrogen sulfide, the hearts were perfused individually with each of the mentioned substances at same single dose of 0.5 mmol/l for 5 min. In collected samples of coronary venous effluent oxidative stress biomarkers were determined using spectrophotometry. Total homocysteine level was significantly higher in the experimental group than in the control group, and the effects of applied sulfur-containing compounds were significantly different in experimental and control groups. DL-homocysteine induced considerable changes in functioning of cardiovascular system even before an increase in plasma homocysteine values, and action of sulfur-containing compounds varied depending on the presence of homocysteine.
