[Hygienic principles of the optimal arrangement of working place for students during the training in computer use].

Experimental studies aimed at hygienic substantiation of requirements for optimal organization of a workplace for schoolchildren using computers have been carried out. Hygienic requirements for basic parameters and design of a desk and a chair intended for those working with computers are presented. Practical recommendations on the equipment of computer rooms in secondary schools are given.

[Hygienic electrooculographic evaluation of working conditions of school children using a computer].

The technique for the electrooculographic analysis of the visual system of schoolchildren working with computers is described. The strain of the oculomotor system and fatigue manifestation have been detected in children under unfavourable environmental conditions. It is recommended to use the derived indicators of evaluating electrooculograms when hygienically assessing the working conditions of schoolchildren using computers.

[Hygienic evaluation of artificial lighting in the classroom for studying information science and computer technics in secondary schools].

Body functioning state of schoolchildren was investigated under different lighting conditions of the computer keyboard and video display terminals (VDT). The findings of lighting engineering and physiologic studies showed that optimal conditions for the children working on computers should be ensured by two interdependent indicators, i. e., the level of lighting at the workplace and on VDT. The most favourable indicators of children's visual functions were established at the level of lighting of 400 lx at the workplace and 100 lx on VDT under general luminescent lighting.

[New technological means in medical diagnosis].

Diagnostic methods using a Pulsar radar measuring computer unit have been developed. The methods are based on the contactless recording of respiratory parameters and pulse and they evaluate human body's functions in real time from the measurements of the duration of cardiac rhythms and calculate the differential function of their distribution and the spectrum of a cardiac rhythmogram.

[Relationship between indicators of equilibrium function and spatial-form perception in children with posture disorders].

The balance function and spatial-figurative thinking (SFT) of children aged 7 to 9 with and without disturbances of bearing were studied. A negative correlation was revealed between balance function and SFT in children with disordered bearing. The results of this study should be taken into account when carrying out hygienic measures for the prevention of bearing disorders in children.

[Characteristics of equilibrium function in preschool children with bearing disorders].

The fluctuations of gravity centre projection of a child's body were studied by computer stabilograph. Investigations showed that children with bearing disorders have lower indices of static and dynamic components of balance function. This results should be taken into account when carrying out hygienic measures aimed at prevention of bearing disturbances in children.

[Hygienic rationale for the allowable weight load of a daily training complex for schoolchildren].

Computed posturography (stabilography) was used to examine the locomotor function of 165 children from 1-11 forms under the influence of different real and model loads. Analysis of age-specific changes in their upright stability (by the data on the lateral velocity of the body's oscillations) yielded allowable load weights of a daily complete set for schoolchildren.
