[Hygienic ranking of basic professions in metallurgical industry according to labor conditions and state of health].

In order to establish priorities in health-improving programs the researchers analyzed the hygienic situation at Novolipetsk metallurgical complex and ranked its technological divisions according to labor conditions of 73 basic professions and state of health of the workers engaged to agglomeration works (AW), chemical-recovery works (CRW), plate rolling (PR) and the workers of a blast-furnace shop (BFS) and an oxygen-converter shop (OCS-I and OSC-II).

[Hygienic problems of population health maintenance under the extremal conditions of North].

A range of multi-sided studies, carried out in various regions of Far North (Jamalo-Nenets autonomous region, Komi republic, Sakha republic (Yakutia)) have established the leading hygienic risk factors of population health deterioration, including those characteristic of small nationalities of North. The consideration of the obtained data, including regional alimentary status peculiarities, the condition of metabolic processes and antioxidant balance of the organism, allowed establishment of effective approaches to the maintenance of notherners' health. These approaches are based upon the optimization of nutrition as an element of population health control under extremal conditions.

[Impact of the climate of the Extreme North and education conditions on young school children].

The scientifically grounded sound regimen is required for schoolchildren, younger ones in particular, who most experience unfavourable environmental factors. Particular emphasis should be laid on the regulation of educational burden at primary school since the irrational distribution of classes leads to the development of fatigue mainly in young schoolchildren and hence to lower working capacities and poor comprehensibility. The investigations have supported the earlier data that the children show the strained body's functional status which is deteriorated by the influence of educational burden.
