Relevance. Problems of injuries and dynamics of working capacity in the production are important characteristics in the analysis of work efficiency, as their assessment allows to identify the advantages and disadvantages of work organization and to identify ways to improve them. However, the existing theoretical concepts do not adequately reflect the real working conditions and work tasks of modern types and forms of work. Further research and expansion of existing concepts are required to incorporate the present findings into the practice of improving the work organization and occupational safety.

Objective. The research aim of the discussed stage was to identify key factors among working conditions and work tasks affecting occupational safety of plant employees.

Methods. The design of the study included two directions – 1) analysis of occupational injuries/errors as integral indicators of occupational safety, and 2) comparison of data gathered from previously performed legal audit of working conditions with data of real-time observations of work process. In total, 209 incidents were analyzed on the sample of 2 professional groups of employees - operators of stamping lines and drivers of forklifts.

Results.

1. The maximum frequency of injury incidents in both group happens in the period between 3d and 4th working hours in all three shifts.

2. The maximum frequency of both injury and errors surprisingly takes place during the first shift (6:00 a.m. - 14:30 p.m.): the ratio of % injuries (from the total) during the first shift to second to third is 56%:22%:3% for operators, 50%:33%:6% for drivers.

3. The key specificity of the operators’ work activity was allocated: they are constantly carrying out tactile quality control on a production line. This work task is not regarded in normative documents and in normative assessment, but is the key psychological factor of work intensity for this professional group.

Conclusion. The specificity of work tasks and conditions at modern production includes implicit factors that are not fully reflected in the regulative documents, and which require theoretical and methodological understanding by work psychology and ergonomics.

Relevance. Scientific and scientific-organizational activity of a world-famous psychologist A.N. Leontiev is a constant interest of specialists in the field of humanistics, methodologists and historians of psychology. In connection with the 115th anniversary of this outstanding scientist, it seems relevant to remind readers of the poorly studied aspects of his life creation.

Objective. Description of contribution А.N. Leontiev in the development of engineering-psychological, ergonomic and reflexive-acmeological problems in the 1950-1970's.

Methods. Science-research analysis (from the positions of reflexive psychology and personology), and methodological analysis.

Results. The author analyzes such aspects of the scientific heritage of A.N. Leontiev, as his fundamental research of productive thinking and scientific creativity, as well as applied developments in the field of engineering psychology and ergonomics. The fundamental contribution of the scientist to modern human studies and to the institutional construction of psychological science is shown. 

Conclusions. Scientific creativity of A.N. Leontiev in the field of psychology is interdisciplinary in nature, because it synthesizes the methodological orientations of modern humanities - natural science, technology cybernetic, social and humanitarian. The crown of the enormous scientific and organizational activity of A.N. Leontiev became a large-scale institutionalization of Russian psychology, which demanded from him not less vision and intuition, intelligence and will, diplomacy and energy than his outstanding creative activity in the field of philosophy, psychology, ergonomics and pedagogy.

The Author discusses the subject, main problems, the social status of psychology of labour, engineering psychology and ergonomics, a parity of these directions of the Russian science in the second half of the ХХ—the beginning of the XXIst century.
