Ergonomic and Human Factor. Impact of Ergonomic Risks on Employee Health and Preventive Measures.

Scientific research is related to the study of physical and mental load of workers in various sectors of the economy. Great importance in research activities is devoted to the human factor in today's changing work environment. Quantitative and qualitative methods are used in research. Objective research methods include the study of muscle fatigue, changes in heart rate, evaluation of applied force, changes in respiratory function during work, etc. Research is also focused on the evaluation of psychosocial risks for employees.
