The Adverse Environmental Impact Factors Analysis on Fly-In-Fly-Out Personnel at Industrial Enterprises

The Functional States of the Participants of a Marine Arctic Expedition with Different Levels of Vitamin D in Blood

(1) Background: The vitamin D level in blood is one of the markers of the functional reserves of the human body and can contribute to more successful adaptation in the Arctic. (2) Methods: The study involved 38 participants in the project "Arctic Floating University-2021". The determination of vitamin D content was carried out at the beginning of the expedition. A dynamic study was carried out for 20 days in the morning and in the evening. The functional state parameters of the participants were assessed using psychophysiological and questionnaire methods. Statistical methods: Mann-Whitney U-test and correlation analysis. (3) Results: It was found that at the beginning of the expedition, the functional state of participants with more severe vitamin D deficiency is characterized by a shorter average duration of RR intervals (p = 0.050) and reduced SDNN values (p = 0.015). The higher the content of vitamin D, the greater increase in speed (r = 0.510), the higher the increase in projective performance (r = 0.485), and the smaller the increase in projective stress (r = -0.334). Significant relationships between the subjective characteristics of functional states and the vitamin D of participants have not been established. (4) Conclusion: With an increase in the severity of vitamin D deficiency in the blood, the adaptive capabilities of participants decrease during an expedition to the Arctic.

Influence of psychosocial factors at work on the non-departmental security officers of the National Guard of the Russian Federation

   An analysis of modern research has shown insufficient study of the labor factors that influence the development of various functional states of non-departmental security officers which allow to develop the recommendations to improve their psychological safety.   The aim of the study. To identify and to describe psychosocial factors at work in relation to the general functional state of the body, stress and performance of non-departmental security officers.   Methods. We used the General Nordic Questionnaire for Psychological and Social Factors at Work (QPSNordic), psychophysiological testing using “Psychophysiologist” device, M. Lüscher color preference test, multivariate statistical methods. The study involved 74 non-departmental security officers of the Arkhangelsk region.   Results. The general functional state of the body, stress and performance, measured by objective and projective methods, are differentially interconnected with psychosocial factors at work. The general functional state of the body is related with the personal attitude to the work performed; stress and performance – with factors of social support, organizational culture and work requirements. The general functional state of non-departmental security officers is favorably influenced by such factors as understanding the goals of the work performed and the expected results, satisfaction with the quality of work and labor safety. Insufficient ability to maintain good relations with the team unfavorably influences the general functional state of the officers. The factors of work intensity include one-type tasks, tight schedule, increased alertness during work and greater precision in movements. Risk factors are associated with strict working hours and insufficient attention of the manage-ment to the opinion and interests of subordinates. At the same time, the environmental resource is the possibility of realizing professional motives and demonstrating mastery in work, as well as a favorable organizational culture.
