[Creating optimal hygienic conditions for students' activities]

Optimization of the preparation of school-children for the working activity may be presented as a model consisting of 4 blocks. Socially significant functions are system-forming factors of this model, i.e. the functions of an organism with which successful implementation of the major types of activities is associated. System approach to the management of schoolchildren's activities based on the dynamic control of socially significant functions and on selective influence on external and internal factors with the help of prophylactic and corrective activities make it possible to maintain its hygienic optimization.
