The purpose of the article is to develop and to implement the method in the educational process of the pedagogical university. It would promote the formation of health-saving competence of students. 202 students of H. S. Skovoroda Kharkiv National Pedagogical University (EG n =152) and Berdyansk State Pedagogical University (CG n=54) participated into the pedagogical experiment. It was developed the criteria (motivational, cognitive-activity, informationalcommunication, reflective-productive) and their levels (high, average, low) for estimation the formation level of certain components of health-saving competence. The motivational criterion was evaluated applying Pashnev methodology, cognitive-active method, Phillips test, information and communication Shmishek test, reflexive-productive method. The experimental implementation of the developed method indicates positive results of the formation of health-saving competence of pedagogical universities' students. The developed method promote the correction of somatic health violations applying a complex of health and medical activities without interruption from the educational process; rationing of the workload and prevention of students fatigue; permanent medical-psychological and pedagogical monitoring of the health condition, physical and mental development of students; to develop and implement educational programs for students to develop healthy lifestyle habits and prevent harmful habits; the effective operation of the psychological assistance service to teachers and students in overcoming stress, anxiety; the formation of a friendly relationship among teachers' staff, etc.
The evolution of a positively charged metallic macroparticle placed into the low-temperature plasma is considered. The influence of the value of the initial macroparticle charge on the dynamics of the electrical potential and temperature of the macroparticle, as well as the possibility of evaporation of a macroparticle due to its interaction with plasma particles are studied. The system of equations of the energy balance and the current balance based on the OML theory, that takes into account the changing of macroparticle potential and its temperature over the time is solved numerically. The solution of the system of equations shows the evolution of the macroparticle potential and temperature within the time interval from the moment when the macroparticle is placed in the plasma until the moment the macroparticle has charged to the floating potential. The positive charge of the macroparticle excludes the thermionic emission and secondary electron emission from the macroparticle surface, as well as the mechanisms of cooling of the macroparticle associated with these emission processes. Analytical expressions that determine the macroparticle potential, the electron current on the macroparticle, as well as the power transferred by plasma electrons in the case when the energy of attraction of electrons to the macroparticle strongly exceeds the energy of thermionic electrons, the energy of secondary electrons and the energy of plasma ions are obtained. A simplified system of equations of the energy balance and the current balance for a positively charged macroparticle is solved; the solution of the simplified equations matches with the solution of the general equations in the region of positive values of the macroparticle potential. Calculations show that during the charging of the macroparticle, its temperature increases up to the boiling point of the macroparticle substance. An equation that determines the conditions under which evaporation of macroparticles is possible has been obtained and solved numerically. The possibility of evaporation of macroparticles of a given size (critical value of the radius) due to initial charging to high positive values of potential is shown. The dependencies of the critical value of the radius on the initial value of the potential for tungsten and copper macroparticles that can be evaporated in a low-temperature plasma are obtained. These solutions bound the region of the parameters where evaporation of a macroparticle is possible and where it is not. The critical values of the potential for copper and tungsten particles with sizes of 0.1 and 1 μm are calculated. The dependence of the radius of a macroparticle on time during the process of vaporization is obtained.
The purpose of the study is to compare at the physiological and functional levels, the effectiveness of speech and music perception among musicians and non-musicians. The study was conducted in 2018 in Ningbo University in Zhejiang Province (China) on 235 students aged 20-21. The results showed that in the experimental group, when perceiving music, symmetrical hemisphere interaction parameters dominate (p ≤ 0.05), in both groups, right-hand parameters dominate in speech perception. The third group showed a difference in the depth of decrease in the amplitude of the alpha rhythm with respect to the resting state (p ≤ 0.03) in the low-frequency range when listening to a fragment of Slavic folklore. The interaction of the cerebral hemispheres determines a high result in the processing of music. The latter manifested itself when listening to Slavic music: the width of the alpha-1 range is wider when listening in comparison with the state of rest.
The paper deals with the theoretical consideration of surface plasmon-polaritons in the graphene monolayer, embedded into dielectric with spatially separated gain and losses. It is demonstrated, that presence of gain and losses in the system leads to the formation of additional mode of graphene surface plasmon-polaritons, which does not have its counterpart in the conservative system. When the gain and losses are mutually balanced, the position of exceptional point-transition point between unbroken and broken PT-symmetrycan be effectively tuned by graphene's doping. In the case of unbalanced gain and losses the spectrum of surface plasmon-polaritons contains spectral singularity, whose frequency is also adjustable through the electrostatic gating of graphene.
The article examines and analyzes the acquisition of digital competence by students studying in medical education institutions in Poland. In order to fulfill the set goal, the analysis and synthesis of search results in information and reference systems was carried out in order to determine the concepts of research, methods of expert evaluation, testing, questionnaires, observation, modeling, forecasting. The process of implementing information processes in the field of health care in Poland is considered against the background of the use of digital technologies in the countries of the European Union in order to ensure the quality of education and accelerate progress towards the Sustainable Development Goals, which were presented by the United Nations and aimed at achieving a digital future for all. In cooperation with the European Commission in promoting digitalization in education, the Polish government is focused on promoting the development of a highly effective digital education ecosystem and improving digital skills and opportunities for digital transformation to ensure bridging the digital divide in education and strengthening competences. A noticeable change in the development of digital competences of students of medical education institutions in Poland is a greater emphasis on the practical use of both these competences and resources available on the Internet. The development of recommendations of Polish institutions of medical education, specifying the various branches of digital health, terminology, learning objectives, optimal approach to training, duration, evaluation method and structure, was considered. The COVID-19 pandemic has increased the importance of digital health in society. Doctors must be properly prepared to work in a new environment, where a greater share of medical care is provided by digital methods, which involves the use of digital technologies, and determines the priority need for future medical workers to acquire the relevant competencies necessary to work with remote consultation models, eHealth systems, processing of medical data.
