[Physiological and psychophysiological indices dynamics in operators with three-shift working day in different working conditions].

It was shown that intense operator work in pulp and paper industry (bleachers and chlorinators) with changes in shift time (day, evening, night) causes fatigue. The fatigue in operators was indicated by increasing number of errors in sensomotor coordination test and coordination index, and among chlorinators it was accompanied by deterioration of state of health. Manifestations of 24 hours' rhythm of physiological functions were detected by changes in body temperature (among bleachers), heart rate, blood pressure and sensomotor coordination indices (all operators).

[Functional state during working shift in workers exposed to occupational hazards in cellulose production].

The authors demonstrated role of chemical factor determining workers' psychophysiologic state at work, defined influence of work conditions jeopardy degree on body functions before and during the working shift in contemporary cellulose production.
