Introduction. The increase in tension and complexity of the naval personnel work is naturally accompanied by an increase in the risk of formation of unacceptable functional states and a critical decrease in professional reliability. Timely detection and prevention of such states is impossible without the implementation of dynamic monitoring of naval personnel working capacity in the process of professional activity. Purpose of research — substantiation of complex technology of functional state and working capacity control of naval personnel. Materials and methods. During performance of work 215 ship experts of various profile of activity were examined. The studies were carried out using an automated functional state screening control system designed on a modular basis and implemented on a number of Navy orders. The results of research. The systems of dynamic control available at the Navy are an effective tool for early detection of borderline functional States of seafarers; determination of the working capacity stage in which the specialist is currently located; development of recommendations for the implementation of corrective measures. However, in real life, these systems are practically not used, there are no guiding documents regulating their application. Implementation of such automated systems on other ship projects requires adaptation and improvement of such systems. In addition, the Navy has no technical means to monitor the functional status of personnel directly during the performance of particularly complex tasks, the struggle for survivability and other extreme situations. Conclusion. The basic concept of screening control and monitoring of the naval personnel functional state in the process of professional activity is proposed.

Purpose. Assessment of functional state of circulatory system in seafarers at different stages independent cruise.Materials and methods. Retrospective analysis of the results of the study of three groups of 180 seafarers on the third, fifth and sixth months of cruise was conducted. The obtained results were subjected to statistical processing according to the rules of variation statistics.Results and its discussion. Functional state of circulatory system in seafarers depends on the kind of military professional activity. Thus, among the staff officers, the number of prehypertensive states is increasing, and for the personnel of surface ships a slightly greater physical working capacity is noted in comparison with divers. At the same time, an increase in the temperature of the skin of the lower extremities was typical for divers, that is definitely important for the control and early prevention of overheating. At the same time, the most noticeable decrease in working capacity is observed in the command staff, while the indicator was quantitatively correlated with the results of daily monitoring of blood pressure and ECG. In addition, it was revealed that the process of adaptation of the body’s regulatory systems reaches its maximum by the end of the third month of cruise and is determined by an increase in endurance and a decrease in morbidity among seafarers.

Self Knowledge

The quality of a teacher's professional activity is closely tied to personal growth. Personal growth, however, is influenced by self-knowledge (K. G. Jung 1994, 2001; Wilber 2010, 2013; Plotkin, 2020; Dispenza, 2015, 2016). Nowadays, there is a shift in the approaches of upbringing and educational work – from a child-focused approach to a child-centered one (OECD, 2019). Therefore, one of the currently relevant skills is getting to know oneself in order to cooperate more successfully with others and be able to accept real-life situations. The results obtained confirm that through the self-knowledge process, teachers get to experience their own personality growth. Categories such as empathy, attitude, and daringness are identified in personal growth.The research shows that by experiencing the procedural activities of self-knowledge with the help of “Get to know yourself!” method and methodological tool developed by the author, teachers improve their emotional responsiveness.The results of the study show that through the experiences gained in the self-knowledge process, teachers learn to integrate new models of action into their pedagogical activities. The aim of the study was to show the importance of self-knowledge in improving teachers' emotional responsiveness in lifelong education, by using the method "Get to know yourself!" developed by the author of the study.The objectives of the study were literature examination and evaluation and work with the target audience by using the author's method and methodological tool "Get to know yourself!".Methods: Literature studies, survey, observation.

Adolescence is a sensitive period of an individual’s way of life projection through an ability of awareness its individuality and self-reflection, self-determination in social, personal, professional and other aspects of life, designing life plans and desire of conscious future’s planning. The purpose of the research is to determine psychological peculiarities of an ability to make a life choice in measuring the self-determination of the students. The self-determination of an individual is determination of the personal orientation vectors in different modes of life activity that is based on a life-sense search. The emergence of life plans in adolescence determines set for professional self-determination of youth that is involved in social production and labor activity that provides the process of “Me” ideas specification in a profession, career and professional plans. The study has been conducted at the National University of Ostroh Academy during 2019-2020. The sample was consisted of 50 respondents aged 20-25 at their 3rd-4th years of studying at different depatments and specialties. It has been diagnosed that the general level of modern youth’s ability to make own life choice is at a low level. During making important decisions, students have shown low ability to manifest independence in the process of self-determination, to resist the influence of others on this process. Due to the weakness of established life-based values, adolescents find it difficult to figure out optimal ways of their capabilities’ realization. Young people have demonstrated sufficient ability to analyze properly all aspects of the situation during making life decisions. Students have an inability of overcoming difficulties and obstacles in life, what prevent making balanced life decisions and the implementation of self-determination at the stage of choosing a profession and mastering professional activity. The inability of overcoming difficulties and obstacles fully prevents from own potential’s realization and taking opportunities, as well as making life balanced decisions, choices and perform self-determination of adolescents in general.

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.

The authors prove the relevance of the study of the effectiveness of professional activities of employees in relation to personal characteristics and functional states in extreme conditions, especially in conditions of the shift work in the Far North. The purpose of the study was to analyze the interrelationship between the efficiency of professional activities of shift workers in a mining and processing factory with their social and psychological qualities and functional states during the shift-work period. Study group: 41 shift workers of the mining and processing factory of one of the diamondiferous deposits of the Arkhangelsk region. Methods of research included the psychological testing, set of psychophysiological techniques. The research show the social-psychological characteristics of the personality such as an evaluation of others as an etalon of oneself, moderate severity of altruistic type of attitude towards people, desire to achieve results in their activities at an average level, ability to control one’s feelings and emotions to be important for the effectiveness of the professional activity of shift specialists. The states of high effective workers are estimated at the level of the norm according to the indices of well-being and mood, the activity is estimated below the norm. The states of high-performance workers are also characterized by heteronomy and a strong degree of predominance of the right hemisphere. Average effective workers have a setting for the result at a level above the average, developed the ability to control one’s feelings, responsibility towards people. The states arising in the course of the labor activity, average-effective workers are estimated to be on average higher than the group of highly efficient workers. They are more autonomous and have a small degree of predominance of the right hemisphere. Employees, judged by experts as average-effective, resort to the use of the adaptation strategy for the emergency job, highly effective workers use economical strategy.

Abstract Discharge of oily wastewater imparts serious threat to the environment because of high level concentration of COD, BOD as well as oil and grease and it is difficult to treat such wastewater due to its inherent toxic and inhibitory property. A treatability study of oily wastewater (carrying petroleum) has been performed in the present work using a batch suspended growth reactor. The experiment was conducted using acclimatized suspended biomass in laboratory environment and the kinetic coefficients were determined which are immensely important for design of such reactor. The oil removal efficiency was observed to be in the range of 62.84–85.45% corresponding to average MLSS concentration range of 1,797–3,668 mg/L. Haldane kinetic model was found to be the best fitted for the biodegradation of oily wastewater with acclimatised microorganisms in the present investigation. The kinetic co-efficients including Ks, Y, kd, k and ki were calculated from the experimental data and the values were compared with published results cited by various scientists. The derived kinetic coefficients values are to be useful for understanding the dynamics of substrate utilisation with production of biomass and efficient design of biological systems and also for pilot plant investigation with real life wastewater of similar nature.
