Документ The dependency of an individual's and state well-being on higher education quality: analysis of Ukrainian students' and employers' opinion(ТОВ "Фінтехальянс", 2022) Moroz, Svitlana; Moroz, Volodymyr; Kalagin, Yurii; Grygoryeva, Svitlana; Sutula, Oksana; Kozlova, Olena; Moroz, OleksandrStatistical information attests to the fact that the share of the Ukrainian population with higher education is one of the largest in the world and comprises more than 82%, which considerably surmounts corresponding indicators for countries with a high level of social and market institutes’ development. A large share of persons with higher education in Ukraine and a comparatively low dynamics of its socio-economic development rise a question of the relevance of the human capital theory for those countries that are currently at the stage of the so-called permanent social and economic transformation. The socio-economic results of such countries’ development suggest certain limitations of the human capital theory, namely those of its postulates whose contents imply the existence of a directly proportional dependency of an individual’s well-being at the level and quality of their education. The controversy between the theory and practices of investment in higher education, especially in the context of comparing an expected and the actual social and economic effect, has determined the need to clarify the opinion of represent-atives of the present-day society concerning the existence of cause-and-effect connections between quality of higher education and well-being. As an instrument for collecting information on the issue of dependency of an individual’s well-being and that of the state on the quality of higher education, the method of polling was selected and applied in the form of a questionnaire. Representatives of student youth and employers from the eastern oblasts (areas) of Ukraine acted as respondents. On the results of the comparative analysis of 747 respondents’ answers, the authors of this article formulate generalizations and conclusions concerning the object of scientific interest. There is sub stantiated the expediency of introducing to the scientific circulation and further use of indicators of social and economic devaluation of higher education in practical activities for estimating state policy’s efficiency in the sphere of higher education.Документ Causec of different waves of machined surfaces after up and down end-milling(Національний технічний університет "Харківський політехнічний інститут", 2022) Dyadya, S.; Kozlova, Olena; Karamushka, D.; Kushnir, E.In modern industry, among the methods of surface treatment is widely used end-milling. Under certain conditions of its use there are self-oscillations, which significantly affect the quality of the treated surface. Various techniques are used to study this influence, in particular, the comparison of the basic fragments of the oscillogram obtained by cutting with the treated surface. It is established that it is formed by the first and last wave of self-oscillations during up and down milling, respectively. But depending on the direction of feed step and the height of the waviness on it have different meanings. Therefore, it is important to determine the reasons that lead to this result. This paper considers the features of each direction of supply that affect the formation of the treated surface. When superimposing fragments of the oscillogram obtained by up milling, it is seen that the deviation of the first wave of self-oscillations from the position of elastic equilibrium starts from the point of incision of the cutter in the part. Therefore, the pitch of the wave on the treated surface depends on the feed and the number of cuts required to cut the first protrusion on the cutting surface. The paper presents a formula for determining the length of the base of this speech. When using it, the discrepancy between the calculated wave step on the treated surface and the measured one does not exceed 4%. In the case of down milling, the last section with waviness on the cutting surface, which is cut and affects the shape of the treated surface, has a shorter base length than the opposite. This is the first reason why the pitch of the wave in the down milling is smaller than in the up. Also at formation of wave on the processed surface at down milling the feature in the form of shift on a phase of waves of self oscillations on each following cut is observed. This increases the cutting time and the length of the cutting surface. Each subsequent forming depression is shifted towards the treated surface with a decrease in its deviation from the position of elastic equilibrium. However, the phase shift direction is opposite to the feed direction. This is the second reason why the pitch of the wave on the machined surface after the down milling is less than after the up. The calculation of the step of the wave of the treated surface after the down milling according to the results of the study of fragments of oscillograms shows that the error does not exceed 12% compared to the measured one.Документ The Internet As an Educational and Communicative Environment for Student Youth(Akademické sdružení MAGNANIMITAS, Czech Republic, 2022) Agalarova, Karina; Sorokina, Hanna; Uhrimova, Iryna; Kozlova, Olena; Sutula, Oksana; Turuta, OlenaIn modern society today, there is the process of general informatization, which is due to the action of certain “information trends”. The leading place in this process is occupied by the emergence and functioning of the global Internet. The rapid development of the global computer network Internet affects various areas of human life and activity. The Internet attracts the active research interest of humanities scientists: sociologists, psychologists, political scientists, economists, lawyers, philosophers. One should note a fairly wide range of humanitarian and scientific problems in the study of the Internet. The relevance of the chosen topic is associated with the rapid development of the Internet and its introduction into various spheres of human life, primarily as a means of mass communication, used, in particular, in the educational and communicative environment. The purpose of the study is to determine the features of the use of Internet channels for the formation and development of educational and communicative environment of student youth.
