[Occupational assessment of computer placement in school areas].

The study included measurements of electromagnetic radiation emitted by MACINTOSH PC placed in public schools, functional state examination of schoolchildren sitting in rows in front of PCs. Electromagnetic radiation emitted by PCs appeared to harm higher nervous activity of the schoolchildren. With consideration of the studies conducted the recommendation is not to set workplaces in rows.

[A hygienic assessment of the work of students on Macintosh computers].

Various kinds of works of 6-11th-form schoolchildren on Macintosh computers were physiologically and hygienically assessed at the lesson of information science and computer engineering (ISCE), as well as typing. The fatigue of a visual analyzer was due to the time of looking through the data available on the display; the adverse changes of the higher nervous activity depends on the complexity of educational materials and the intensity of work on a computer. Three-hour studies in ISCE should be excluded from the time able of lessons as they do not meet hygienic requirements.

[Hygienic bases of the work schedule of 10th grade students at the time of industrial practice using personal computers].

Psychophysiologic studies covered 10th grade pupils with normal and short sight, who worked at IBM PS/2(VGA) during summer. If compared to normal-sighted ones, the shortsighted pupils demonstrated drastic functional changes. The studies set optimal duration of work at the PS-2 hours or no more than 3 hours with obligatory prophylaxis.

[Hygienic evaluation of the work of technical school students on the video display terminals].

Psychologic and hygienic examination of students working on display calculating complexes (DCC) DCC-2 and DCC-3 during the extra study time revealed the features of their functional status caused by the DCC design and work schedule. Positive role of eye exercises during the work was stressed. 6-hours duration of students' work was considered as unfavourable.
