Forecast of Professional Success of Employee under Stress Factor: A New Approach

A new personalized approach is proposed to predict the professional suitability of railway transport workers under the influence of stressful factors, based on the study of the effect of salivary fluid of subjects before and after a work shift on the intensity of the glow of the bioenzyme reaction of luminous bacteria: NADH:FMN-oxidoreductase+luciferase. The integral method, which signals the magnitude of the stress effect, is based on changes in saliva components such as lactate, ions and cations, as well as nitrate and sulfate chlorides under the influence of stress. This made it possible to identify, using the example of Russian Railways dispatchers, a risk group and a group of stress-resistant workers, which is important to reduce accidents at Russian Railways. The conditions that reduce the stressful workload necessary for the development of effective measures for the prevention of stressful situations and the preservation of workers’ ability to work have been identified.
