The influence of production factors on working capacity and adaptation to working conditions

Abstract

The purpose of the study is to assess and predict the adaptation of workers of coke-chemical production to working conditions. An assessment is presented to the influence of harmful production factors on the body of workers of coke-chemical production in the process of adaptation to working conditions. The level of influence on the body of harmful production factors was estimated with using a method of multidimensional mathematical analysis of experimental data - solid correlation analysis. For this, intrasystem and intersystem links of physiological systems (PhS) were determined. With using the method of mathematical analysis, the diagnosis was carried out and the evaluation criteria were specified making possible to evaluate and predict the current state of health and level of efficiency of physiological systems. Quantitative criteria are specified for identifying the groups of "risk" and disability depending on the share of participation in professional and production activities, age and experience. Analysis of the systemic interaction of the PhS showed the predominance of intrasystem links over intersystems. The factor disperse analysis showed that the PhS stress indicators reflecting the condition of the body's functions were worsened with an increase in not only age, but also professional experience. Indicators of the age - length of service categories of the surveyed workers completely repeat a set of compensatory connections formed in the studied age groups, which made it possible to assume the existence of a single regulatory mechanism that ensures the sustainable functioning of the body as a biological system. It is shown that the low level and premature performance decrement, the exhaustion of functional reserves of the body's adaptation to the effects of a complex of harmful factors of the production environment significantly reduce occupational fitness of workers in the system "Man - labor factors - health". Keywords: working conditions, adaptation, factor analysis, diagnosis, intersystem and intrasystems links.
