Thermal conditions in petroleum tanks are important for maintaining optimal sanitary and hygienic standards, which contribute to increasing the working capacity of people. Therefore, the set problems are of great importance for research. The main goal of the work is to study the influence of environmental technologies on the economic component. To achieve this goal, the authors substantiated design solutions for the use of refrigeration equipment to improve and normalize thermal conditions in drilling galleries in the extraction of oil by underground. It is established that the main increase in air temperature is observed in the drilling gallery and on the outgoing air jet in the slope. According to the results of thermal surveys, it is determined that the cooling demand of the drilling gallery, provided that the air temperature at the end of the slope does not exceed 35.0°C, is about 1000 kW. It is established that the use of environmental technologies contributes to the improvement of working conditions. And also has a high level of profitability and payback.

Modern high-tech industry intensifies the production load on operators. The problem of maintaining a high level of working capacity and error-free work is growing. Earlier studies revealed that the work of operators in hermetically sealed rooms is characterized by the following: monotony, hypokinesia, lack of psychological and industrial contacts, static muscle tension, as well as a lot of frequently repeated small movements caused by the fact that the technical system is controlled indirectly — through the remote control. The operator is affected by the factors of a closed production environment (microclimate) and the labor process (work and rest mode, long working shifts), which together form a general status called fatigue. The main factor that causes fatigue is the integral extensive intensity of the activity. The dynamics of physiological processes characterizing fatigue and the possibility of erroneous actions were evaluated. It is established that low-intensity factors, which form the working conditions of operators of high-tech industrial complexes, provoke persistent fatigue, a decrease in the functional reserves of the body, the development and aggravation of professionally caused diseases. The degree of fatigue was assessed by the indicators of the latent time of sensorimotor reactions, the stability of attention and the error of actions. The obtained data confirm the need in developing effective ways and means of maintaining working capacity. In particular, the regulated breaks and pauses filled with the specially developed schemes of isometric exercises, should be introduced (according to a special schedule) into the work and rest mode with a 12-hour schedule. The study substantiates the need for further making recommendations on the development of preventive measures to optimize the working conditions of the operators in high-tech industries.

Introduction. A healthy lifestyle is one of the most eff ective methods of preserving health and preventing non-infectious diseases. The mechanisms and factors that infl uence the formation of motivation for health and a healthy lifestyle in employees engaged in harmful working conditions have not been suffi ciently studied. The study of these mechanisms will allow us to more eff ectively shape health-saving behavior.The aim of the study is to study negative aff ectivity, social suppression and anxiety in the formation of motivation to maintain health and a healthy lifestyle in coal industry workers.Materials and methods. A survey was conducted of 75 employees of mines and sections in the South of Kuzbass with an established diagnosis of occupational diseases, as well as 54 people who do not work in harmful working conditions (engineering and technical workers). Surveys were conducted using the method “Index of motivation to health and a healthy lifestyle”, the presence of personality type D was conducted using the DS14 questionnaire, the level of personal and situational anxiety was assessed using the Spielberger — Hanin questionnaire.Results. Th e level of motivation for health and a healthy lifestyle among patients with occupational diseases is signifi cantly lower than the level of motivation for the health of engineering and technical workers. Th e infl uence of negative reaction and social suppression on the level of motivation for health and a healthy lifestyle was not found. Th e level of situational anxiety also has no eff ect on health motivation. A higher level of personal anxiety among people with a high level of motivation for a healthy lifestyle was determined.Conclusions. Personal anxiety aff ects the level of motivation for health and a healthy lifestyle in people with occupational diseases.

The aim of the study was to assess the professional risk of developing diseases in workers of the railway car repair enterprise. The Voronezh Car Repair Plant, a branch of Vagonremmash Joint-Stock Company, was chosen as the object of study. Methods: «The methodology for calculating individual occupational risk depending on the working conditions and the health status of the employee», developed by the Klin Institute for Protection and Working Conditions in conjunction with the Research Institute of Occupational Medicine (2013), the main professions; cohort study with the calculation of the relative risk of morbidity with temporary disability, the odds ratio, the etiological share of factors in the formation of morbidity (group size: 250 people, experimental group — workers of the main specialties, 95 people — comparison group). Results. According to the research results, the priority factors of occupational health risk include: chemical, noise, heating microclimate, low light level. For certain professions, the share of the contribution of priority factors to the risk profile (PV) reaches 40 %. The indicator of individual occupational risk is 0.12 to 0.26 units. The high level of professional risk (0.22 ÷ 0.26) is characterized by the working conditions of the mechanics for the repair of rolling stock, machine tools (woodworking), casters (metal), thermists, plastic casters. In professional groups with medium and high risk, the indicator of the relative risk of morbidity with temporary disability is higher than 1 (RR = 1.75 and 1.39, respectively), and the etiological share of production factors in the formation of diseases is from 27.95 (subgroup with secondary professional risk) up to 42.88 % (a subgroup with high professional risk), which indicates the professional condition of the disease. Discussion. In general, our data are consistent with the results of similar studies conducted earlier at the car building and car repair enterprises. In order to ensure hygienically safe working conditions and preserve the health of workers, it is necessary to reduce the level of exposure to production factors, including through the introduction of modern equipment and improvement of technological processes.

Modern buildings with new heating, ventilation and air conditioning (HVAC) systems offer possibility to fit parameters of the indoor environment to the occupants’ requirements. The present paper describes the results of measurements performed in an office room in the first Polish passive commercial office building during four months of normal operation. They were used to calculate parameters describing thermal comfort: vertical air temperature profile, floor surface temperature, predicted mean vote (PMV) and predicted percent of dissatisfied (PPD). Obtained results confirmed good thermal conditions in the analysed room. The average temperature of the floor’s surface varied from 20.6 °C to 26.2 °C. The average vertical air temperature, calculated for working days, was from 22.5 °C to 23.1 °C. The temperature difference between the floor and 5 cm below the ceiling was from −0.9 °C to 6.3 °C. The PMV index varied from 0.52 to 1.50 indicating ‘slightly warm’ sensation, in spite of ‘neutral’ reported by employees. Also measured cooling and heating energy consumption was presented. The performed measurements confirmed the ability of thermally activated building system (TABS) to keep good thermal conditions.

The features of the thermal regime of the surface air layer in the Debed river basin are considered. A statistical analysis of the average annual and average seasonal values of air temperature from 1964 to 2018 was carried out, two periods were identified, their time course was shown. The analysis was carried out using data from six meteorological stations representing the lowland, mountain and high-mountain climatic zones of the Debed river basin. A correlation was obtained between the absolute altitude and the monthly average values of air temperature for January and July, which can be used to assess the thermal conditions of unexplored or poorly studied territories and for cartography. The time course of average values of air temperatures for the seasonal period has been studied. Analysis of trend lines of temporal changes in air temperatures shows that in all situations on the territory of the basin as a whole, there is a tendency of temperature growth. Moreover, with a range of interannual fluctuations, a break in the course of temperatures in the early to mid 1990 is clearly visible, after which their significant increase began. It turned out that a significant increase in seasonal temperatures is observed especially over the period 1993-2018, which means that the annual warming after the mid 1990 occurred primarily due to summer and spring seasons. The regular dynamics indicates that in the studied area in terms of temperatures, a tendency of softening winters, a decrease in the water content of rivers, aridization of the climate. The results obtained can be used to assess the regularities of the spatial-temporal distribution of the temperature of the study area, to clarify the thermal balance, for the rational use of heat resources, as well as in the development of strategic programs for longterm analysis.

Topography and canopy play a decisive role on air temperature (T) conditions in forested areas. Air temperature is a crucial factor in decision making process for the development of these areas. To our knowledge, there is no information regarding the effect of topography along with canopy cover (Pc) on thermal conditions of a vulnerable mountainous forested region of Greece, Mount (Mt) Aenos in the island of Cephalonia, Ionian Islands, Greece. Therefore, the purpose of our work is the investigation of the aforementioned parameters, especially the effect of altitude (alt) and Pc on T of Mt Aenos. Mean values for maximum air temperature (Tx) and Pc were estimated for twelve sites at various alts in Mt Aenos during the period May-October of three consecutive years (2011-2013). The analysis of the results showed that Tx was related to alt and Pc. Altitude has a greater effect on T in relation to Pc. When examining same or similar alts, an increase of Pc up to 51% resulted in a significant decrease of Tx (p<0.05) up to 3.6 °C. Our findings could be taken into account in planning the construction of hiking trails for recreational activities in Mt Aenos, and, in general, in mountainous forest areas of special importance.

In the years 2004-2006 in Kraków, phenological observations of climbing roses were conducted in order to determine the length and dates of their flowering period. The diameters of their flowers were also compared. Eight flowering repeating cultivars were selected for the experiment: 'Climbing Souvenir de la Malmaison', 'Dortmund', 'Golden Showers', 'Goldstern', 'New Dawn', 'Parade', 'Sympathie' and 'White New Dawn'. During the studies, the shrub roses were not artificially watered in order to create conditions similar to those prevailing in public green areas. It was observed that irrespective of the air temperature pattern in a given year, the studied cultivars did not bloom before 15 June. In 2006 high temperatures (above 20<sup>o</sup>C), which continued throughout the whole flowering period, caused its shortening, and the interval between the first and the next flowering in the season lasted longer than in the previous years. In the years 2004-2006, the cultivar 'New Dawn' bloomed the longest. In 2005 the studied cultivars produced larger flowers than the next year. The cultivars 'Dortmund' and 'White New Dawn' were characterised by the smallest diameter of flowers, whereas 'Climbing Souvenir de la Malmaison', 'Golden Showers' and 'Parade' were marked by the largest diameter.

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.

It is impossible to ensure sustainable business development without solving the maintenance of labor resources issues that are included in the manufacturing process, as well as involving new employees to increase labor potential. The company can effectively confront the new challenges by attracting highly qualified employees for whom a high level of safety is important. Therefore, an important direction of sustainable business development is to increase the level of safety and create a comfortable working environment and optimize working processes to increase the efficiency of production activities, as well as prepare for the challenges that may arise in the process of company development. The article analyzes the statistics and structure of the socio-economic damage to business due to unsatisfactory working conditions and a high level of injuries on the example of the machine-building sector, and also considers aspects of maintenance of labor resources and ways to involve additional labor resources to ensure sustainable manufacturing development. Based on conducted analysis, an algorithm of implementation of managerial decisions was developed, aimed at ensuring the safety of personnel who carry out the work activities at the workplace, taking into account the modern concept of the “green workplace”. Involvement in the working process of additional labor reserves is carried out by creating favorable working conditions, assessing the special needs and level of ability of workers for optimization of working processes and increasing their efficiency.

In England, teacher shortages have worsened in recent years and one contributor is the declining rates of retention among newly qualified teachers (NQTs). We employ a method developed in the health-statistics literature to identify schools that both recruit an unusually high level of NQTs and lose an unusually high level of NQTs from the profession. We show that this small group of schools, which are likely characterised by poor working conditions, are responsible for a disproportionately large amount of attrition from the teaching profession. This has a material effect on overall teacher shortages and comes at a high cost to taxpayers. Policy solutions, including improving the flow of information to NQTs to help them avoid such schools, are discussed
