A transformation in modern production and an increase in workload
requires an improvement in the occupational psychophysiological selection, the search
for new approaches for its implementation, and the creation of special ways for the
evaluation of the psychophysiological state of workers. The aim of this investigation is
to develop an approach for the quantitative evaluation of the efficient reduction in risk
in worker’s occupational activity, and the probability of health and safety depletion
during the entire life period of work.
Materials and Methods:
The investigation is
based on the data of 110 psychophysiological indicators, received from a survey that
encompassed the workers of operative service in electric power engineering industry of
Ukraine. The data was examined using statistical tools, factor analysis, and multivariate
regression models.
Results:
The developed technique made it possible to determine the
statistical significance and to estimate the impact of the important phychophysiological
factors on the level of success in the occupational activity of workers under dangerous
circumstances. The model includes the variable that describes the age of the worker and
provides analysis for 4 categories of ages.
Conclusion:
The important factors that
influence the risk of reduction in occupational efficiency of the workers are variability,
the total error, and the number of positive values according to the pendulum methodolo-
gy; the average reaction time according to the square-circle technique; variability
according to the square technique; and adaptability and time of the task performance
according to the adaptability methodology. The workers belonging to the same age
group do not significantly change the risk of depletion in their occupational efficiency
