Среда обитания судового экипажа определяет его работоспособность и оказывает влияние на эффективность принимаемых решений в нормальных и аварийных ситуациях. Рассмотрены основные факторы, формирующие среду обитания: состав воздуха служебных помещений, освещенность и светоцветовое оформление, шум, вибрация, производственные излучения и электромагнитные поля. Проанализированы возможности адаптации организма к специфическим условиям среды обитания. Приведён перечень необходимого оборудования, которое используется для защиты персонала, в том числе стационарные газоанализаторы, обеспечивающие замеры низких концентраций токсичных газов и концентраций кислорода, а также выполняющие периодический контроль состава воздуха в служебных помещениях. Показано влияние условий труда на заболеваемость. Предложена методика экспертной оценки условий труда и обитания экипажа, учитывающая влияние комплекса факторов, совокупность которых может существенно меняться не только в зависимости от назначения и типа судна, но и вследствие особенностей плавания. Анализ природных и производственно-бытовых факторов, влияющих на заболеваемость членов экипажа различных профессиональных групп, позволил выявить частоту возникновения болезней и их продолжительность. Установлено, что чаще болеют представители операторских профессий (штурманы и механики), что объясняется условиями и характером их труда. Заболеваемость имеет выраженную профессиональную обусловленность (уровни воздействия) и стажевую детерминацию (длительность воздействия). The habitat of the ship's crew determines its performance and influences the effectiveness of decisions made in normal and emergency situations. The main factors that form the living environment are considered: the composition of the air of office premises, illumination and light-color design, noise, vibration, industrial radiation and electromagnetic fields. The possibilities of adaptation of the organism to specific environmental conditions are analyzed. The list of necessary equipment that is used to protect personnel is given, including stationary gas analyzers that provide measurements of low concentrations of toxic gases and oxygen concentrations, as well as perform periodic monitoring of the air composition in office premises. The influence of working conditions on morbidity is shown. A method of expert assessment of the working conditions and living conditions of the crew is proposed, taking into account the influence of a complex of factors, the totality of which can significantly change not only depending on the purpose and type of vessel, but also due to the dynamically changing features of navigation. The analysis of natural and industrial and household factors affecting the morbidity of crew members of various professional groups allowed us to identify the frequency of diseases and their duration. It is established that representatives of operator professions (navigators and mechanics) are more often ill, which is explained by the conditions and nature of their work. The incidence has a pronounced occupational conditionality (exposure levels) and an occupational determination (duration of exposure).

The article is devoted to the role and contribution of major repairs of tenement buildings for sustaining a comfortable human living environment, which is directly linked to a region’s living standards. The author identifies the constituents of a living environment and the factors influencing its maintenance in the framework of normative regulation. Major repairs include the maintenance of the performance properties — eliminating the physical deterioration and obsolescence of a tenement building, as well as ensuring the tenants’ and other persons’ safety (in terms of a wide variety of microclimate-creating factors like the quality of breathing air, lighting, noise, vibration, etc.) during and after the repair works. However, it does not target the principal technical and economic characteristics. In compliance with legal and normative regulations, major repairs programs target parts of hard assets and public premises of a tenement building. The author proposes a methodological approach to the assessment of the factors affecting the quality of life during and after the major repairs. The approach is based on the well-known method of socio-economic research involving a systemic analysis, which incorporates the multitude of interdependent and interrelated living-environment-forming factors.

Introduction. Appropriate decision-making is essential in emergency situations; however, little information is available on how emergency decision-makers decide on the emergency status of the patients shifted to the emergency department of the hospital. This study aimed at explaining the factors that influence the emergency specialists’ decision-making in case of emergency conditions in patients. Methods. This study was carried out with a qualitative content analysis approach. The participants were selected based on purposive sampling by the emergency specialists. The data were collected through semistructured interviews and were analyzed using the method proposed by Graneheim and Lundman. Results. The core theme of the study was “efforts to perceive the acute health threats of the patient.” This theme was derived from the main classes, including “the identification of the acute threats based on the patient’s condition” and “the identification of the acute threats based on peripheral conditions.” Conclusions. The conditions governing the decision-making process about patients in the emergency department differ from the conditions in other health-care departments at hospitals. Emergency specialists may have several approaches to decide about the patients’ emergency conditions. Therefore, notably, the emergency specialists’ working conditions and the others’ expectations from these specialists should be considered.

The research on factors that affect employee motivation at Bentre Import Export Joint- stock Corporation (Betrimex) has special significance in motivating employees, attracting and retaining talent, thereby helping the Corporation improve work performance. During the research, 300 employees working at Betrimex were surveyed and 250 employees with valid answer sheets were selected, survey data was processed with the SPSS software and the research model through scale reliability analysis, exploratory data analysis, correlation analysis and multiple regression analysis was tested. The research results have shown 07 factors affecting employee motivation at Betrimex, measured through 37 observed variables and including the pay, bonuses, benefits, allowances, working conditions, relationships with colleagues and relationships with superiors. Where the pay (b = 0.403) is the factor that has the most powerful influence on employee motivation and working conditions (b = 0.171) have the least influence on employee motivation. The results of multiple regression analysis have also showed that the adjusted R2 is 0.732. Thus, 07 independent variables can explain 73.2% of the variations of the dependent variables. Also, the research results have tremendous implications for developing strategies and plans for human resources development of Betrimex in the future.

Introduction. The analysis of working conditions of pilots of civil aviation aircraft has been carried out according to the data of sanitary and hygienic characteristics (SHC). The non-compliances with hygiene standards for several factors have been established at the same time in all SHC. Materials and methods. The 220 SHC of pilots, who had been examined in the clinic of FSBSI RIOH due to suspicion of occupation disease from 2015 to 2019, conducting flights by plane (49%) and helicopter (51%) were analyzed. The methods of account of acoustic load, hygiene assessment and classification of working conditions, peer review methods, and statistical treatment methods have been used. Results. The working conditions, according to the criteria of the Guide R 2.2.2006-05, are assigned to the following classes: 3.2 - in 26%; 3.3 - in 41%; 3.4 - in 33%. Exceeding the permissible equivalent noise levels was recorded at 92% of workplaces. According to SHC, the exceedances were from 1.2 dB to 34.5 dB (class 3.1-3.4). In assessing the work intensity in 83% of cases from 5 to 11 indicators of class 3.2 were recorded. It has determined class 3.3 of work intensity. The levels of general vibration exceeded hygiene standards in 48% of cases (class 3.1- 3.2), local vibration - in 8% (class 3.1-3.2), microclimate parameters - in 67% (class 3.1-3.2), labour severity - in 22% (class 3.1-3.3), less often there were discrepancies in light (6%) and chemical factor (2%). Conclusion. According to a combination of factors, the overall assessment of working conditions of the pilots of civil aviation aircraft in 74% of cases is assigned to classes 3.3-3.4. However, the disadvantages and errors in filling out the SHC can underestimate the degree of harmfulness of the work. To improve the procedure of establishing the connection between the disease, and the profession it is necessary to amend the legislative framework to obtain objective information about the levels of factors affecting pilots, develop a separate form of SHC of working conditions of pilots, detailed instructions about the rules of filling out SHC.

Introduction. Working conditions, clinical and laboratory status of 236 workers of a chromium mine were investigated. Materials and methods. The observation group included 162 underground employees working in conditions of the combined impact of negative occupational factors (dust, noise, vibration, tension and severity there, cooling microclimate) - class 3.3-3.4. The comparison group included 74 mine employees working in acceptable working conditions - class 2. Results. In the observation group, the pathology of the cardiovascular and endocrine system (ICD-10: I00-I99, E00-E07) was detected 2.8-3.3 times more often (p = 0.001-0.02), the relative risk of disease formation was 2.7-3.2 times higher than in the comparison group (RR = 2.7-3.2; DI = 1.44-9.2; p = 0.001-0.02). Under the conditions of the combined effect of negative production factors, as features of metabolic disorders, it was noted that the most unfavourable - abdominal form of obesity was diagnosed 1.4 times more often (42.0%, p = 0.013), the atherogenic index was 1.2 times higher, and the level HDL is 1.2 times lower than in the comparison group (p = 0.017-0.047); “Metabolic indices” - lipid accumulation coefficient (LAP) and visceral obesity index (VAI) were 1.2-1.4 times higher than the values in the comparison group (p = 0.001-0.048). Conclusions. To implement a complex of medical and preventive measures aimed at increasing life expectancy and working longevity, early prevention of CVD, including among those working in the extraction of chrome ore, it is advisable to consider the introduction of the calculation of early markers of metabolic disorders - VAI and LAP indices in the medical examination programs.

This study analyzed a group of 20 patients undergoing duckbill vocal restoration at Ohio State University to determine if certain variables could predict success. Of the 20 patients, 19 developed successful speech. The 10 variables studied were age, alcohol use, living environment, stoma size, hearing acuity, educational level, work status, eye-hand coordination, concomitant medical problems, and current mode of communication. A multiple correlation analysis of this data was undertaken and alcohol abuse and stoma size were found to have the highest correlation with developing successful duckbill speech. A formula based on these two variables has been derived that will predict the patient's success. It is the conclusion of this study that since patients are not uniformly successful in developing duckbill speech such a formula is of value in predicting success and should help the clinician identify patients who may have difficulties.

The densities and heat capacities per unit volume of aqueous solutions of propionamide, methylacetate, ethylacetate, methylethylketone and diethylketone, and bis(2-ethoxyethyl)ether were measured over the whole solubility range with a flow densimeter and a flow microcalorimeter. Most systems were studied at 10, 25, and 40 °C. Properties of the pure liquids were also measured whenever possible. The derived apparent molal volumes [Formula: see text] all decrease with concentration in the water-rich region, except with ethyl acetate which increases at high temperature. In general the more hydrophobic the solute the more negative the initial slope. All apparent molal heat capacities [Formula: see text] decrease as a function of concentration and the decrease is more important for more hydrophobic solutes. The apparent molal expansibilities [Formula: see text] are obtained from [Formula: see text]. They are positive for all solutes but, at low concentrations, they are smaller than the corresponding molar value of the pure liquid. Various factors affecting hydrophobic interactions are examined.

Interactions between normal, protease-sensitive prion protein (PrP-sen or PrPc) and its protease-resistant isoform (PrP-res or PrPsc) are critical in transmissible spongiform encephalopathy (TSE) diseases. To investigate the propagation of PrP-res between cells we tested whether PrP-res in scrapie brain microsomes can induce the conversion of PrP-sen to PrP-res if the PrP-sen is bound to uninfected raft membranes. Surprisingly, no conversion was observed unless the microsomal and raft membranes were fused or PrP-sen was released from raft membranes. These results suggest that the propagation of infection between cells requires transfer of PrP-res into the membranes of the recipient cell. To assess potential cofactors in PrP conversion, we used cell-free PrP conversion assays to show that heparan sulphate can stimulate PrP-res formation, supporting the idea that endogenous sulphated glycosaminoglycans can act as important cofactors or modulators of PrP-res formation in vivo. In an effort to develop therapeutics, the antimalarial drug quinacrine was identified as an inhibitor of PrP-res formation in scrapie-infected cell cultures. Confirmation of the latter result by others has led to the initiation of human clinical trials as a treatment for Creutzfeldt-Jakob disease. PrP-res formation can also be inhibited using a variety of other types of small molecule, specific synthetic PrP peptides, and an antiserum directed at the C-terminus of PrP-sen. The latter results help to localize the sites of interaction between PrP-sen and PrP-res. Disruption of those interactions with antibodies or peptidomimetic drugs may be an attractive therapeutic strategy. The likelihood that PrP-res inhibitors can rid TSE-infected tissues of PrP-res would presumably be enhanced if PrP-res formation were reversible. However, our attempts to measure dissociation of PrP-sen from PrP-res have failed under non-denaturing conditions. Finally, we have attempted to induce the spontaneous conversion of PrP-sen into PrP-res using low concentrations of detergents. A conformational conversion from α-helical monomers into high-β-sheet aggregates and fibrils was induced by low concentrations of the detergent sarkosyl; however, the aggregates had neither infectivity nor the characteristic protease-resistance of PrP-res.
