[Hygienic evaluation of the capacity of preschool institutions in relation to planning and equipment of group facilities].

The area of the group premises in child preschool centers (50 m2) with the existing number of children in a group (25) does not provide hygienic conditions for the organization of regime requirements. Physiological studies of the functional status of children, ergonomic calculations and pedagogical observations made it possible to recommend that the number of preschool groups should be decreased down to 20 children.
