[The effect of circadian rhythms on the body functional status and the work capacity in operators]

Lately more and more attention is given to the indices of efficiency and safety of operators' activities because of their special complexity and mistake value. Operators' work is connected with intensive processing of encoded information and is accompanied with development of significant fatigue, stereotype cyclic alternation, changes in work and rest regimen--with necessity of working at night. Effect of circadian biorhythms considerably influences on characteristics of operators' activities. The existing organizational approach considers the operator only as being present or absent at working place. The fact that operator can be present but his working capacity is not sufficient is taken into account not enough and that's why requires consideration of operators' work and elaboration of organizational measures.
