Railway transport is a huge energetic system, the functioning of which is determined by the coordinated work of thousands of employees of various specialties, including dispatchers and locomotive drivers. In the "man-technical system-production environment" system, a person is the "weakest link", determining the reliability and safety of the system's functioning as a whole. Studies show that the driver's work in conditions of high-speed traffic involves a high level of stress on the nervous analyzers, as well as the functions of memory and attention, which leads to their rapid fatigue. The level of fatigue obtained as a result of the work shift is unacceptable for most workers, monitoring the level of functional reliability of the worker can be an effective means of combating accumulated fatigue. The problems of ensuring the normal life of workers in dangerous professions in modern social and industrial conditions are caused primarily by the intense influence of negative social, professional and other factors that cause the development of adverse mental states and overstrain of psychophysiological functions. All this creates stressful situations, both in society in general and for every person. Of course, in addition to the above-mentioned stresses, an important place in the activity of a human operator is occupied by professional stress, which is constantly present. The systemic impact of stress has both an immediate and remote nature. Experimental studies have established that it reduces the level of functional reliability of the "human operator". Such states include, first of all, fatigue, stress and borderline states (between health and illness). Such indicators can be an indicator of high danger of such a relevant phenomenon for the transport industry as sudden ischemic death. A distinction is made between the slow and operational components of performance, while the slow (trend) does not change for a long time (month, years), and the operational (functional state) changes in the form of "peaks", "declines" or a relatively flat "plateau" during hours. It follows from this that in order to maintain the appropriate level of safety of the transport process, it is necessary to implement control of the level of efficiency of railway operators, including its trending part, taking into account the presence of constant stresses today. It is necessary to conduct monitoring as a prediction of early diagnosis of changes in the functional state of operators, and therefore the state of professional reliability. Keywords: safety, ergonomics, diagnostics, professional reliability, level of functional reliability, trend component.

This paper reports a study the into processes of plasma-electrolyte formation of heterooxidic coatings on titanium alloys for the photocatalytic destruction of natural and man-made toxicants. The synthesis of coatings was carried out from aqueous solutions of diphosphates under a galvanostatic mode. For a quantitative description of photocatalytic reactions, the constants of the reaction rate kf from the linearized dependences ln(Ct/C0), where Ct is the current, C0 is the initial concentration of the reagent, were calculated. The morphology of the coating surface was investigated by atomic force microscopy, and the results were visualized by reconstruction of the relief in the form of 2D and 3D topographic maps. Morphological features of coatings made of titanium oxide (IV) and heterooxidic composites containing oxides of transition metals were analyzed. It is shown that the specific surface area remains an effective factor in regulating the photocatalytic activity of coatings. The establishment of the morphology of heterooxidic composites, as well as methods for controlling this parameter of the target product, is a constant component of the systematic study of such materials in determining their functional properties. It has been established that compared to oxide-titanium coatings whose surface layers are characterized by a toroidal mesostructure, heterooxidic compositions have a more developed surface, which has a positive effect on their functional properties. Subsequent heat treatment similarly affects the properties of the coating. The speed constants of the photocatalytic decomposition of the methyl yellow-hot azo dye were used to rank coatings of different composition according to their functional properties. Coatings from TiO2·ZnO showed the highest catalytic activity among the materials studied – kf is 5.26 10-3 min-1, which is several times higher than the corresponding value for TiO2

The article deals with the problem of the labour protection state in railway transport. The transport sector, in particular the railway, is one of the main country's activity spheres, which significantly affects the level of its social and economic development. The analysis of statistical data shows that the transport industry is one of the leaders in the most trauma-hazardous human activity spheres. Thus, the analysis of injury rates and factors determining the professional reliability of locomotive crews, and the scientific substantiation of measures set aimed at preserving the health of railway transport workers and ensuring the safety of railway transport, are urgent and essential tasks. The article's purpose is a comprehensive analysis of the injury's actual state in railway transport. In the work, it is established that during the performance of their duties, railway transport employees are affected by physical, chemical and biological harmful production factors. The work is carried out under the influence of psychophysiological factors caused by the severity and intensity of the labour process in conditions of hydrodynamic and fixed working posture. It was determined that the influence of adverse factors complex leads to disruption of the cardiovascular, central nervous and endocrine systems activity. The authors assessed the actual state of industrial and non-industrial injuries in railway transport. It has been established that the number of industrial accident victims has been gradually increasing in recent years. This indicates the need to develop and implement in practice a set of measures to improve the working conditions of mainline locomotive crews. It is noted that the key areas of measures to preserve the health and professional capacity of railway transport workers are the improvement of regulatory and legal support, socio-economic motivation of workers, and organizational-technological and sanitary-medical measures. Keywords: injury, accident, railway transport, labour protection.

У даній статті досліджено причини виникнення Європейської політики сусідства. Охарактеризовано причини поширення Європейської політики сусідства на Україну. Визначено основні напрямки співпраці України з Європейським Союзом в рамках даної політики, також які зміни відбулися у різних сферах розвитку нашої держави внаслідок дії Європейської політики сусідства. Зроблено висновок про те, що ЄПС мала ряд недоліків, не влаштовувала ряд країн ЄС, зокрема Польщу, та не відкривала для України тих можливостей яких потребувала наша держава.
