Introduction. Digital technologies are actively used in the work of specialists of medical centers of various profiles, which causes the impact on employees of a number of professional factors that determine the characteristics of their work. The aim of the study is to evaluate the influence of professional factors on the functional state of the employees' body and the glutathione system as an objective indicator of stress based on the analysis of the subjective perception of the medical center employees of the specifics of working with personal computers and psychophysiological testing. Materials and methods. The study involved 109 specialists of medical centers (25 ophthalmologists, 31 representatives of the secondary medical staff - nurses and paramedics, 53 office employees). The anonymous survey concerned the assessment of working conditions and their impact on the functional state of the body of the respondents. Performance and stress tolerance indicators were evaluated using three standard questionnaires. The study of 66 subjects' levels of glutathione in the blood: total, reduced, oxidized and the ratio of reduced and oxidized - was used to analyze the relationship of the neuro-emotional nature of labor with the reaction of oxidative stress. Statistical processing of the obtained data was carried out using traditional methods of variation statistics and calculating the value of the odds ratio (OR) with a 95% confidence interval (CI). Results. The survey revealed a significant proportion of people in all groups of respondents who constantly use computer technology in their work. Describing the quality of the processed information, doctors more than representatives of other groups note its complexity, importance, negative emotional color, a high degree of responsibility and tension. Doctors more often than average medical staff and office workers associate the manifestation of fatigue with an uncomfortable state of the visual organ, nervous system, and musculoskeletal system. The subjects showed reduced performance and stress tolerance with the most pronounced negative trends in the group of doctors. Changes in the glutathione system were detected, indicating the presence of oxidative stress in 40% of ophthalmologists and office workers, and in half of nurses. Conclusions. The work of specialists of medical centers of various profiles in accordance with their assessment is characterized by high nervous and emotional stress, due to the need to process a significant amount of complex and important professionally significant information. Subjectively noted by respondents the influence of working conditions on the functional state of the body is confirmed by indicators of the glutathione system, which can be used as indicators of nervous and emotional stress.

The article gives the results of the research on the influence of a developed complex liposomal preparation on the dynamics of morphological and biochemical indicators of the blood of rats subjected to modeled oxidative stress caused by intermuscular injection of 50% carbon tetrachloride at a dose of 0.25 ml per 100 g of body mass. We found that in conditions of intoxication by carbon tetrachloride, the physiological level of hematological indicators of the researched animals’ body was disrupted. This is indicated by the reduction in the amount of erythrocytes, hemoglobin content, concentration of hemoglobin per erythrocyte, increase in the amount of leucocytes, mass of hemoglobin per erythrocyte and increase of colour indicator. Also, we detected suppression of protein synthesis function of the liver. The levels of total protein and albumin fraction were below the normal physiological level. High indicators were observed in the levels of creatinine, urea and total bilirubin. In order to normalize the functional state of the liver under oxidative stress it is reasonable to use a liposomal preparation which contains butafosfan, interferon, thistle and vitamins. In order to normalize morphological and biochemical indicators of the blood of rats subject to intoxication of carbon tetrachloride it is reasonable to use a liposomal preparation that contains butafosfan, selenium, thistle, methionine and vitamins. Using the liposomal preparation Butaselmevit for rats under oxidative stress the morphological and biochemical indicators in the blood normalized. On the 14th day the indictors of the number of erythrocytes, the hemoglobin content, the white blood cell count and red blood indexes compared to control came within the physiological indicators, indicating a recovery of hematopoietic function of the bone marrow and normalized indicators of the functional state of the liver.

The paper focuses on results of substantiating and selecting informative physiological criteria that can be used for assessing and controlling functional state and working conditions category taking into account physical and nervous-emotional loads borne by CNC- machinery operators. Basing on complex physiological and ergonomic studies and retrospective data analysis, we showed that workers from various occupational groups who dealt with physical labor had to face certain strain over a working shift. Such strains, given long-term working experience, could result in neuromuscular system overstrain and occupational diseases occurrence. We substantiated and developed informative physiological criteria that allowed assessing and controlling functional state and working capacity as well as working conditions category taking into account occupational activities. The present research involved using a set of occupational studies, physiological and ergonomic procedures as well as clinical and statistic ones for examining peculiarities related to functional state of workers’ bodies under exposure to occupational factors taking into account specific working tasks and loads. It allowed us to substantiate labor intensity assessment. Our research results revealed that there was a strong correlation between hand muscles endurance to static exertion (decrease in % by the end of a work shift) and working conditions category given local and overall muscular loads borne by workers. This criterion is recommended for control over functional state and working capacity taking into account occupational peculiarities and gender-related differences. It is necessary to accumulate scientific data for confirming a similar correlation between overall physical working capacity (OPWC) and working conditions category. Results obtained via physiological research were used for developing prevention activities for workers.

Abstract. Introduction. The relevance of the research topic is due to the need to develop and scientifically substantiate physiological criteria for assessing working conditions in difficult cases according to indicators of the functional state of the body (in accordance with the section "General hygienic assessment of working conditions" of Guideline R 2.2.2006-05). The aim of the work is to determine changes in the functional state of the body in workers of mental, visual-intense, physical activity on the basis of complex physiological and hygienic studies to substantiate quantitative physiological criteria for different classes of labor intensity. Materials and methods. Complex industrial physiological and hygienic studies included an assessment of the degree of labor intensity with the analysis of retrospective data, physiological studies of the central nervous system, visual analyzer, neuromuscular apparatus, cardiovascular system of mental workers (52 groups), visually stressful (32), physical labor ( 71 professional group). Statistical processing of the obtained data was carried out using the statistical software Statistika 10, Microsoft Excel 2010. Research results. It is shown that the depth and time of the onset of physiological changes depend on the degree of labor intensity, which makes it possible to calculate the percentage of decrease in functions, taking into account the intensity class of the labor process. The list of physiological criteria for confirming the class of working conditions is determined by the characteristics of labor activity, with mental work these are indicators of concentration of attention and the volume of working memory, with visually intense labor, the critical frequency of fusion of light flashes, with physical labor, muscle endurance and heart rate. Conclusions. Quantitative physiological criteria have been established for various types of labor activity, which provide a valid evidence-based assessment of the class of working conditions according to the characteristics of the intensity of the labor process and control of the levels of the functional state.

Operator Functional State

To improve the safety and the performance of operators involved in risky and demanding missions (like drone operators), human-machine cooperation should be dynamically adapted, in terms of dialogue or function allocation. To support this reconfigurable cooperation, a crucial point is to assess online the operator’s ability to keep performing the mission. The article explores the concept of Operator Functional State (OFS), then it proposes to operationalize this concept (combining context and physiological indicators) on the specific activity of drone swarm monitoring, carried out by 22 participants on simulator SUSIE. With the aid of supervised learning methods (Support Vector Machine, k-Nearest Neighbors, and Random Forest), physiological and contextual are classified into three classes, corresponding to different levels of OFS. This classification would help for adapting the countermeasures to the situation faced by operators.
