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.

Introduction. The profession of “machine operator in metalworking”, one of the most common professions in various industries, characterized by a large volume of abrasive operations, accompanied by dust formation, which creates a potential for the occurrence of diseases of the visual organ.The aim of the study is to provide a hygienic assessment of working conditions and occupational risk of visual organ pathology in metalworking machine operators.Materials and methods. Observation groups — machine operators for metalworking of two training groups (experience up to 5 years, experience of 6–20 years). Two comparison groups (administrative and technical personnel of the enterprise) are formed according to the same age-experience principle.Results. The working conditions of machine operators were classified as class 3.2. taking into account the severity and intensity of the work process and the noise level (80 dBA) in the workplace. Nitrogen oxide, carbon monoxide, and manganese were registered in the air of the working area in concentrations below the permissible concentration (PC), and the aerosol dihydroxide was registered above the PC in 25.8% of cases. In the main working groups, diseases of the anterior segment of the eye were more often registered, among which dry eye syndrome (DYS) prevailed (94.1%), chronic blepharoconjunctivitis (79.9%), persistent corneal opacification (21.7%). There was an increase in the prevalence of detected diseases with an increase in work experience (p≤0.05). In machine operators, the frequency of inhibition of lacrimal formation and decreased stability of the tear film was recorded significantly more often, with increasing work experience, the degree of violation of lacrimal formation and stability of the tear film increased. The chances of detecting pathology of the anterior segment of the eye in machine operators are 5.9 and 3.5 times higher than in the comparison group. There are different forces of connection, increasing with the increase of work experience in the profession, between the working conditions of machine operators and the occurrence of SHG (relatively strong), with chronic blepharoconjunctivitis and persistent corneal opacity (medium strength), which suggests the professional conditionality of this pathology.Conclusions. The results obtained suggest that the pathology of the anterior segment of the eye is professionally conditioned in metalworking machine operators and necessitate the introduction of preventive measures aimed at protecting the visual organ.

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.

Introduction.Methanol and its derivatives occupy one of the leading places among the main organic synthesis intermediates in terms of their importance and scale of production. According to experts, by 2027 the global demand for methanol can reach 135 million tons, the annual growth will be about 5.5%. However, there is little information regarding the assessment of working conditions and occupational risks for workers in modern methanol production and its derivatives.The aim of the studyis hygienic assessment of working conditions and the formation of health risks in workers of modern production of methanol and methylamines.Materials and methods.The assessment of the main adverse factors of production is given. When studying the state of health, objective indicators (the results of an in-depth medical examination) and subjective (the results of a quantitative assessment of the risks of the main pathological syndromes associated with health) are considered.Results.According to long-term observations, the concentration of harmful substances in the air of the working area, indicators of labor severity, parameters of physical factors met hygienic requirements, with the exception of industrial noise exceeding the maximum permissible level, as well as labor intensity of 1 degree. The General assessment of working conditions corresponds to the category of harmful 2 degrees (3.2). According to the results of the medical examination and quantitative assessment of the risks of health disorders in workers, the most significant were functional disorders and diseases of the circulatory system. The levels of somatic pathology on the part of the main body systems were significantly higher in apparatchiks compared to the engineering and technical personnel (ETP).Conclusions:In the production of methyl alcohol and methylamines, the main hygienic importance is the impact on workers of the complex of harmful substances of 1-IV hazard classes in low concentrations, increased levels of industrial noise, labor intensity of 1 degree. According to the subjective assessment of health and medical examination, the greatest prevalence of health risks in workers was observed from the circulatory system, and the levels of the revealed somatic pathology were statistically significantly higher in apparatchiks compared with the ETP.

This article analyses to what extent the social and solidarity economy (SSE), the aim of which is to prioritize people’s needs and well-being, can offer young people education-to-work transitions conditions and opportunities which are different from those in the conventional economy. The very nature of SSE means that it is especially suitable for challenging gender inequality and proves to be exceptionally useful for testing feminist economics. Against a backdrop of economic crisis, SSE has shown greater resilience when compared to other sectors, although it is still not widespread. To examine how SSE can improve young women’s experiences and labour trajectories, this article analyses working conditions, job satisfaction and gender roles in school-to-work transitions of young women in SSE in Catalonia. Results show that the collective and value-driven nature of SSE entails a specific awareness and commitment that empower young women’s transitions experiences and expectations.

Resumen: El presente artículo tiene como objetivo analizar los yacimientos de inserción profesional y las condiciones laborales de las tituladas y los titulados en Ciencias de la Actividad Física y el Deporte (CAFyD) a través de un estudio comparativo entre sexos. Para ello, en el año 2013, se administró un cuestionario a un total de 1.000 personas egresadas en CAFyD por las universidades catalanes. Los resultados indican que no existe una discriminación directa en las condiciones de trabajo, para un mismo cargo mujeres y hombres presentan condiciones similares. En cambio, sí que se ha detectado una discriminación indirecta fruto de la carga social y cultural que afecta a las preferencias de las mujeres a la hora de escoger un determinado yacimiento de inserción.Abstract: This paper aims to analyse the sources of employment for university graduates in Physical Activity and Sport Science through a gender-based comparative study. With this objective, in 2013, a questionnaire was administered to total of 1,000 university graduates in Physical Activity and Sport Science from Catalan universities. The results indicate that there is no direct discrimination in working conditions, for a same position women and men share similar conditions. However, an indirect discrimination has been detected as a result of the social and cultural burden that affects the preferences of women when accessing and choosing a particular insertion field.
