About career orientation of modern students: foreign and domestic approaches

The article considers the problem of career and career orientation of modern students in domestic and foreign scientific psychological and pedagogical literature. It is emphasized that the concepts of “career” and “competition” are etymologically related concepts. It is noted that a successful career involves a competitive personality. Three integral characteristics of a competitive personality are characterized: orientation, competence, flexibility. It is noted that the mental development of a cultured person occurs through the appropriation of social consciousness – social ideas, knowledge, language, ideals, norms, traditions, assessments, which are stored in the culture of the people and which in the transition to the internal plan form the psyche of a particular person. It is proved that in senior courses a professional identity is formed and the final decision is made whether to connect one's future destiny with the chosen profession or not. Based on the results of the theoretical analysis of career understanding issues, foreign and domestic researchers have identified the main approaches to career understanding: semantic, role, value, procedural, status, personal-professional, biographical, acmeological. It is emphasized that the process of formation of professionalism throughout the life of students is self-realization and the formation of its subjectivity. It is noted that the most popular foreign theory of professional development was the model of D. Super

Features of transition modes of friction surfaces with partially regular microrelief

Textured surfaces with partially regular micro relief (PRMR) are reported to be an effective means to control lublication. It was found they are good wear debris trap and suppliers of lubricant directly to the actual friction area. Their tribological properties depend on the clearance between mating surfaces, relative slip speed, direction of motion. These parameters change the lubrication regime, and vice versa changing geometry of PRMR it is possible to predict and control lubrication regime for given conditions. Application of micro textured surface is prospective for high precision sliding units – valve slides of oil and hydraulic systems, faces of gear pump gears, ring-to-cylinder interface of aircraft reciprocating engines etc. providing high service life. On other side, changing texture parameters it is possible to stop the leakage of fluid through the gap, what may be efficiently utilized in aircraft non-contacting mechanical (hydrodynamic and hydrostatic) seals of gas compressors and gear mechanisms. This paper discloses some peculiarities of transition lubrication regimes for textured surfaces in lubricated contact

The friction mechanism between surfaces with regular micro grooves under boundary lubrication

The results of research related to the influence of partially regular microrelief parameters on the adhesion component of the friction factor under boundary lubrication are presented. It has been shown that micro grooves are effective under boundary friction on precision surfaces with low roughness when lack of film and probability of seizure appear. The deformation component of the friction force of surfaces with micro grooves has been studied. The time of micro running-in was the key factor while assessing the dependence of the deformation component on friction when taking into account the depth of micro grooves and their relative area. The research was conducted using a tribometer according to the friction model entitled “shaft & flexible steel tape”. First published online: 02 Jul 201

Wpływ sportu na kontrolę emocjonalną u kadetów Gwardii Narodowej Ukrainy na początku wojny

The ability to adequately respond to various emotional situations is vital for law enforcement officers to work effectively in peacetime. In times of war, the importance of emotional control increases. Material and methods. A survey (in Google forms) of cadets of the Kyiv Institute of the National Guard of Ukraine (n=282) was conducted. Depending on whether they played sports, the respondents were divided into 2 groups (n=171 and n=111, respectively). Spielberger’s method was advocated. And the Courtlaud Emotional Control Scale. Results. The anxiety levels of athlete cadets and those who had stopped regular training did not differ. An average level of emotional control was recorded. The anxiety control score was close to low. Significant differences were found in the anxiety and depression control scores of cadets who regularly performed physical exercise and those who did not participate in sports. Conclusions. At the beginning of the war, the level of anxiety among cadets was high. Among cadets who play sports, there was no high level of anxiety control, aggression, or depression, as expected from athletes. This can be explained by the different intensity of emotions and their control, as well as the insufficient duration of sports training among cadets.Zdolność do adekwatnego reagowania w różnych emocjonalnych sytuacjach jest niezbędna funkcjonariuszom organów ścigania do skutecznej pracy w czasie pokoju. W czasie wojny znaczenie kontroli emocjonalnej staje się jeszcze większe. Materiał i metody. Przeprowadzono ankietę (na formularzach Google) wśród kadetów Instytutu Gwardii Narodowej Ukrainy w Kijowie (n=282). Respondentów podzielono na 2 grupy w zależności od tego, czy uprawiają sport (odpowiednio n=171 i n=111). Zastosowano metodę Spielbergera, jak również Skalę Kontroli Emocji (Courtlaud Emotional Control Scale). Wyniki. Nie było różnicy w poziomie lęku u kadetów uprawiających sport i u tych, którzy zaprzestali regularnego treningu. Odnotowano średni poziom kontroli emocjonalnej. Wynik w zakresie kontroli nad lękiem był bliski niskiemu. Znaczące różnice stwierdzono w wynikach kontroli lęku i depresji wśród kadetów uprawiających regularne ćwiczenia fizyczne i u tych, którzy nie uprawiali sportu. Wnioski. Na początku wojny poziom lęku wśród kadetów był wysoki. U kadetów uprawiających sport nie wystąpił wysoki poziom kontroli lęku, agresji lub depresji, czego można się spodziewać po sportowcach. Można to wyjaśnić inną intensywnością emocji i ich kontrolą, jak również niewystarczającym czasem trwania treningu sportowego u kadetów
