[Occupational hearing loss--problem of health and safety].

On the basis of the literature review the critical analysis of the recommendations (the letter of Ministry of Health of Russia from 6/11/2012 N 14-1/10/2-3508) on occupation noise-induced hearing loss (HL) assessment is presented. Need of more strict criteria of HL assessment for workers, than for the general population according to ICF (WHO, 2001), in order to avoid growth of accidents and injury rate is proved. The illegitimacy of a deduction of statistical presbiacusia values from individual audiograms as human rights violation is stressed. Some terminological defects are noted. It is necessary to cancel recommendations and to develop the sanitary norms or state standard with the program of hearing conservation at work.

[Information as physical factor: problems of measurement, hygienic assessment and IT-automation].

The increasing flow of information, speeding up the progress of society, can impact the health that puts the task of its hygienic reglamentation. The physical aspects of information, parameters and units of quantities, aspects of measurement and evaluation with account of information quantity and quality as well as criteria of its permissible and optimal levels are considered. The results of measurements of quantity of text information produced per year on computer in 17 occupations of 10 economic sectors are presented. The principle of IT-automation of operator's work and of dynamic monitoring is proposed. On the basis of research performed the glossary of terms and guide on the problem with computer support are elaborated for the accumulation of experience and clarification of prospects.

[Information hygiene and regulation of information for vulnerable groups of the population].

Development of information society engenders the problem of hygienic regulation of information load for the population, first of all for vulnerable groups. There are presented international and Russian normative legal documents and experience in this area, there are described the negative effects of information (such as stress, depression, suicidal ideations). There are considered social-psychological characteristics of vulnerable groups that requires their best protection from loads of information, doing harm, particularly in terms of reproductive health, family relationships, children, etc. There was noted the desirability of improvement of sanitary, legislation on the regulation of the information load on the population, especially in vulnerable groups, in terms of optimization of parameters of the signal-carriers on volume, brightness and the adequacy of the volume and content of information in radio and television broadcasting, in an urban environment and at the plant to preserve the health and well-being of the population.

[Effects of information media on population health]. / Vliianie informatsionnoi sredy na zdorov'e naseleniia.

Analysis of sociohygienic statistical values brought the author to a conclusion that deterioration of health of the Russian population and increased mortality, particularly from causes associated with information, is directly (increased morbidity and disability caused by mental disorders) and indirectly (cardiovascular diseases) determined by unfavorable information media of Russia, and deterioration of population health in general is indicative of negative effects of information on population health in Russia.

[Characteristics of the development of emotional stress in persons with different levels of physical fitness]. / Osobennosti razvitiia émotsiona'lnogo stressa u lits s razlich- nymi urovniami fizicheskoi podgotovlennosti.

Emotional stress is one of the most important problems. Until now scientists can't determine a norm of physical state which is characteristic of human stress resistance in the extreme conditions. The study is designed to analyze the dependence of stress resistance in young males on their physical fitness. Physical capacity for work has been established in young males aged 17-24 by means of PWC170 test. Modelling of the novelty with an element of personal risk has been carried out for the complex study of emotional stress. During the first appearance of those under experiment on the beam placed at the height of 10 m, the changes occurring in their omega-potential, vegetative indices according to heart rhythm and arterial pressure were investigated. Predominance of parasympathetic regulation and higher values of omega-potential in persons with general physical capacity for work of 18 kg.m/min.kg and higher were set forth. They could indicate their higher stress resistance and psychic capacity for work.
