State of the problem. The success, reliability and safety of work in operator’s and "extremal" professions depend on forming and maintaining the system of professionally important qualities (PIQ). It does not exist as the finished product, but is formed in the course of the acquirement of professional knowledge, skills and abilities. Modern psychograms often simply include certain categories of PIQ, psychological and physiological elements (their equivalents), specific for certain activities, whereas it is necessary to study in detail the structure of PIQ for forecasting the development, performance, management and improving the reliability of operators. Purpose: to define the structure of PIQ complexes for representatives of different occupational groups at AES, in order to raise the quality of their occupational psycho-physiological selection and corresponding maintenance of the mentioned categories in the process of their work activity.
Materials and methods. 278 workers of Zaporozhskaya atomic electrical station (AES) have been examined. The complex examination was made, using equipment “Mortrest”. The technology for psycho-physiological examination (PHE), developed in Ukrainian Institute of Transport Medicine, covers tests on studying higher psychic and mental functions. The factorial analysis of factor rotation by “varymax” method was used, presenting statistical analysis PASW Statistics 18.0, as a mathematical instrument.
Results and discussion. According to the results of professiographic analysis there have been distinguished 3 groups of AES workers: drivers, technical personnel and operators of energetic systems. The structural models have bee developed using factorial analysis. The relationship of main blocks of psychophysiological reaction, applicable to occupational activity, has been considered. The common peculiarities have been defined, characterizing the higher nervous activity in general as well as particular features in each group. Conclusions: The structure of PIQ factors was defined for drivers, technicians and operators of nuclear power plant. It reflects peculiarities of their occupational activity, indicating the nature of intra-relationships and their specific value. The hypothesis on the dynamic adjustment of the combination of psychophysiological properties of operators, providing for their occupational activity in changes of work-related problems, is presented. The results can be used for improving the methodological base and criteria for operators’ psychological examination in various branches of industry, transport and power engineering.
