[The current problems of electromagnetic safety in computer classes]. / Aktual'nye problemy élektromagnitnoi bezopasnosti v komp'iuternykh klassakh.

He paper presents the data on the present-day situation in the computer classes in general educational schools to show electromagnetic safety. It shows that most of 37 classes do not satisfy the requirement of electromagnetic safety and proposes modes of elimination of this danger.

[Topical problems of hygienic certification of computers]. / Aktual'nye problemy gigienicheskoi sertifikatsii komp'iuterov.

The paper provides evidence that while making a hygienic certification of computers it is necessary to rely not only on their physical and technical data, but on the characteristics obtained by defining the integral physiological parameters of the quality of displayed information perception. According the state standards CaH [symbol: see text] 2.2.2.54-96, their hygienic certification requires differential assessment of computers with the age-specific features of users (pre-school and young school children, middle- and old-aged schoolchildren, adults). It is proposed that CaH [symbol: see text] 2.2.2.54-96 should be supplemented by a regulation on choice of special working places with appropriate protective devices for the children of a risk group.

[Hygienic problems in the use of computers by school children with refractive disorders]. / Gigienicheskie voprosy ispol'zovaniia kompiuterov shkol'nikami s narusheniiami refraktsii.

The influence of 0.5-hour computer loading on accommodation, critical frequency of a flicker, vision capacity for work, the function of the central nervous system was studied. Significant functional changes were revealed in schoolchildren with myopia. Protective screens were found to improve their functional indices. Therefore, children with myopia should be identified as a risk group to regulate their work regimen.

[The individual measuring of the health-promoting impact of the sauna on preschoolers]. / Individual'noe dozirovanie ozdorovitel'nogo deistviia sauny na doshkol'nikov.

The paper deals with the role of individual grading of heat loading when preschool children take a sauna. The adaptative reserves of the child's body were determined by thermal imaging just during exposure in the thermal chamber. The time course of the maximum skin temperature, which was determined by a thermal imaging computer, was used as an informative indicator. The degree of adaptative reserve exhaustion was calculated by approaching to the extreme (maximum) temperature, by the degree reduction in the efficiency of heat emission through diaphoresis and by the rate of maximum skin temperature changes. There were great differences in the adaptative reserves during thermal procedures in children of the same age. The ways of reliable instrumental management were found by grading thermal procedures.
