Technological factors and processes contributing to the scintillation mechanism have been considered in quaternary garnet ceramics doped with Ce(Gd,Lu)3Al2Ga3O12. The super-stoichiometric additive of gadolinium in the material composition or its co-doping with a low concentration of Mg were found to be effective tools to suppress phosphorescence in the quaternary garnet, confirming that it is not an intrinsic property of the material. The Monte-Carlo simulation of electronic excitation transfer demonstrates that the hopping migration along the gadolinium sublattice plays an essential role in forming the scintillation kinetic parameters. Breaking the integrity of the gadolinium sublattice by substitution with heavier lutetium ions increases the role of self-trapped states in the excitation of Ce3+ ions, which ensures both an increase in the fraction of short ~20 ns and very long ~600 ns components in the scintillation kinetics.

Summary:In modern social and economic conditions the condition of genesial health (further -GH) the female population remains to one of the most acute medico-social problems, being a national security prominent aspect. Research objective: scienti ically to justify a complex of the preventive actions referred on optimization of medico sanitary maintenance of women working on chemical synthesis. Materials and methods: work is based on the systemic approach to a studied problem. Following methods are applied: sanitary-and-hygienic and sanitary-statistical. Effect of factors of industrial medium were evaluated on value of hygienic parameters in premises of shops of Open Society «Grodno Nitrogen» in a place of work of the patients, received at realization of gauging at the next certi ication of jobs for working conditions. For an estimation of condition GH of working women of chemical synthesis results of periodic medical examination and a condition of a case rate with time disablement (further -TD) during 2008-2012 are studied. At studying of a condition of genesial health of women working on Open Society «Grodno Nitrogen» it is established, that their professional work in the conditions of effect of harmful production factors of the chemical, physical and psycho physiological nature is accompanied by its aggravation that is shown by growth of a gynecologic and extra genital case rate, and also an obstetric pathology including with temporary disablement. For prophylaxis of disturbances GH of the yielded contingent of working women introduction of a complex of sanitary-and-hygienic, socially-hygienic, treatment-prophylactic actions is necessary.

Introduction. Currently, the work of managers is characterized by a number of factors having an unfavorable impact on human health. Stress as the main risk factor related to the professional activity is considered to be the major cause of possible poor health among the managers. Depression may result from a stress overload of managers. Aim. The authors wanted to determine the vulnerability to depression related to professional stress among healthcare managers and to assess gender and managerial work experience-specific differences. Materials and methods. A total of 235 healthcare managers working in the Republic of Belarus with various length of managerial work experience (women n=142, men n=93; mean age 45.7±1.21 years) underwent a psychological testing aimed at determining their vulnerability to depression. The results of the study were analyzed using the STATISTICA 7.0 software. Results. The vulnerability to depression in men differed from that in women (p=0.002). The predisposition to depression had significant differences between the groups with various experience of managerial work (p=0.03). The vulnerability to depression among healthcare managers increased with the length of managerial work. The highest level of vulnerability to depression was in healthcare managers with >20 years of experience (p=0.02) both in men (p=0.003) and in women (p=0.04). Conclusion. Thus, acquiring professional competences as a factor contributing to stress resistance, skills of coping with stress and alleviating its impact on the health status is very important through the whole professional activity. Healthcare managers with the length of work experience of 1-5 years are especially in need of the appropriate knowledge and skills.
