The subject of the research is the problem of monitoring and troubleshooting in distributed high-load systems. The most common mistakes in design and development, methods of their forecasting and solutions are described. In this article, the author describes the most popular tools that are currently used in the development of high-load systems and the main mistakes when working with them from a developer's point of view.This article describes a set of tools, the implementation of which can significantly reduce the time spent searching for vulnerabilities, describes the difficulties in choosing a set of metrics technologies - ELK / EFK, describes their advantages and disadvantages. The analogs of the tools used are analyzed in detail. The main conclusions in the work are:- the need to develop the infrastructure for monitoring the system from the beginning of the project development, due to which it is possible to correct the high complexity of the project at the stage of its development.- it is necessary to use the most popular tools for which there is a large amount of information in open sources, for example, on the Internet. This approach will reduce the time spent on fixing errors that can be caused by a specific set of tools.- the company needs not to save on highly qualified personnel, which in the future will save a lot of time on fixing problems, reduce the time for developing new functionality and allow spending a minimum of time to support and test the already developed functionality.- when analyzing problems, it is worth paying attention to public resources in which other companies, most likely, have already solved similar problems. For example, the Facebook company has been dealing with the monitoring problem for a long time and has developed a large number of tools to solve this problem. They also collect a large number of system records for analyzing the behavior of the system under any circumstances.

In the modern world, against the background of the flourishing of scientific and technological progress, more and more industries appear in which traditional and specific work is no longer performed by people, but by robots. Automated mechanisms turned out to be able to replace the functions of loaders, vehicle drivers, and assemblers on the conveyor. For a long time medicine remained an exclusively "live" industry, in which the presence and participation of competent and highly qualified personnel was necessary. However, in the last century already, mankind had the opportunity to learn about the da Vinci robotic system, capable of performing the most complex and high-precision operations, and recently, specialists from Hong Kong have developed a robot nurse Grace, designed to perform the functions of paramedical personnel. The impetus for the creation of a robot nurse was the coronavirus pandemic, in which medical workers took the whole blow, and, unfortunately, proved to be very vulnerable to infection. Against the background of the colossal rate of infection of the medical staff, very often medical workers became victims of this dangerous disease; there was simply no one to look after the patients, and the remaining staff was unable to cope with the enormous workload. Therefore, Hong Kong scientists came up with the idea of giving a "medical orientation" to the previously developed humanoid robot Sophia, dressing it in a medical uniform and equipping it with the necessary skills.

Aim. A theoretical review of the opportunities and functions of the application enabling the creation of internet surveys. Assessment of their use in accordance with own opinion and the analysis of the literature on the subject.Methods. Analysis of the literature on the subject and a summary of the description of the survey conducted on the basis of a questionnaire examining the interesting phenomenon of e-methodology and an opinion on distance learning. The authors analysed the advantages and disadvantages of the tools used in online research. The aforementioned experiences of the researchers refer to the experience gained during research on e-methodology.Results and conclusion. The interest in this medium as a tool for social and psychological research has been growing rapidly in the last ten years. The very rapid development of technology that has taken place during the COVID-19 pandemic allowed us to easilyconduct a research survey using the network, which can easily replace any labour-intensive data collection through inquiry. In addition, many different tools and techniques have been created that use the so-called “Global spider web” in conducting my own research. Theresearcher abandons direct contact with the respondent and devotes himself to the analysis of the phenomenon that interests him by analysing the given Internet environment, social groups that express themselves on a given topic or share their work on specifi c problems. However, the global network is not only a chance for good, innovative approach to research, but also threats and related difficulties. One of the most important weaknesses of the network is the fact that we can never be sure who is on the other end of the computer.Cognitive value. Presentation of new ways of conducting scientific research via the network, presenting my own analysis of the advantages and disadvantages of the e-methodology phenomenon. Analysing the phenomenon of internet methodology, welearn that the tendency to participate in internet research is increasing. However, motivation to participate in internet research is not always sufficient, as mentioned by many researchers. There are many ways to infl uence the attractiveness of the research and the motivation to participate in the research. Thanks to this article, we also learn that it is still necessary to conduct further methodological research on increasing the effectiveness of Internet research and minimising errors associated with it. The issues presented in this article reflect the current methodological knowledge. We can predict that as the Internet grows and new technical opportunities emerge - such as video-enabled applications, among others - new methodological issues will arise that may be of interest to researchers.

The article is devoted to the topical issues of performance evaluation and management of university research groups for its sustainable development. Scientific groups are one of the effective levers for increasing and activation of research activities in the university, as they cover all areas of its activities: performance of research and development work, building a portfolio of orders, preparation of applications for intellectual property objects, preparation of articles and reports, training of highly qualified personnel and implementation of expert activities. To develop a methodology for assessing the effectiveness of research teams, the existing methods for analyzing the management of research activities of universities in Russian and world practice were considered, where their advantages and disadvantages were identified. The university’s organizational and economic mechanism of research activities management was developed based on the above and the principles of sustainable development of higher education institutions.

Статья посвящена актуальной для теоретической и практической психологии проблеме проявления волевых свойств спортсменов, во многом определяющих возможность реализации ими своего потенциала. Кратко обоснована важность изучения волевой саморегуляции спортсменов, осуществляемой с помощью волевых свойств личности, среди которых особое значение имеет настойчивость, определяющая способность человека мобилизовать свои силы ради длительной борьбы с трудностями, в том числе в спортивной деятельности. Подчеркнуто, что развитие у спортсменов такого волевого качества, как настойчивость, несомненно, будет способствовать достижению ими высоких спортивных результатов и совершенствованию личности в целом. Обозначен методологический аппарат проведенного авторами эмпирического исследования: объект, в качестве которого выступала волевая сфера личности спортсменов; предмет — особенности настойчивости спортсменов-единоборцев высокой квалификации; задачи, среди которых прежде всего было выявление особенностей проявления и психологической структуры настойчивости спортсменов, а также гипотеза о том, что настойчивость данной группы спортсменов является системным свойством личности, структурная организация которого определяется функциональным единством содержательно-смысловых и инструментально-стилевых составляющих, обеспечивающих их готовность к реализации настойчивых действий. Раскрыта суть системно-функционального подхода к анализу свойств личности, в соответствии с которым настойчивость спортсменов рассматривалась как система содержательно-смысловых (целевых, мотивационных, когнитивных, продуктивных) и инструментально-стилевых (динамических, эмоциональных, регулятивных, рефлексивно-оценочных) составляющих. Представлены результаты эмпирического исследования вышеназванного свойства личности, позволяющие оценить его сильные и слабые стороны и наметить действенные пути развития и гармонизации в целях повышения результативности спортивной деятельности. The article treats a relevant issue of theoretical and applied psychology, namely the issue of combatants’ persistence as a character trait which enables sportsmen to fully realize their potential. The article substantiates the significance of investigating the nature of sportsmen’s volition and self-regulation. It maintains that persistence is a character trait which enables a person to mobilize their potential in order to meet challenges including challenges in their sporting career. The article underlines that the development of persistence in sportsmen will undoubtedly contribute to their sporting achievements and personal evolution. The article describes the methods of empirical research, the subject of the study (persistence in sportsmen), the object of the research (peculiarities of highly-qualified combatants’ persistence), the objectives of the research (the psychological structure of persistence in sportsmen) and the hypothesis that persistence in combatants is their inherent character trait which can be defined as a unity of various meaningful and instrumental components, which is responsible for sportsmen’s insistence and resilience. The article focuses on the essence of the systemic-functional approach to the analysis of personality traits, according to which persistence in sportsmen is viewed as a system of meaningful (volitional, motivational, cognitive, productive) and instrumental (dynamic, emotional, regulatory, evaluative) components. The article presents the results of an empirical study of persistence, which enables the authors to assess both advantages and disadvantages of this character trait and to assess its potential improvement and harmonization as a means to improve sporting achievements.

At the present stage of the development of society, significant educational changes are taking place – the general education school is being reformed, which ensures the transition of Ukrainian education to a new European level. It is clear that this is due to the objective requirements of the time, because modern children live in an information-dynamic environment that requires flexible and quick adaptation to its constant changes, which means that modern educational institutions should be ready to teach the so-called Internet generations. The first step in the reform of education in Ukraine at this stage was the "New Ukrainian School" - this is a platform for reforming secondary education, which originates from elementary school. It provides that students learn through practical action, not theory, and develop skills. A significant factor in the successful implementation of the tasks of the New Ukrainian School is the involvement of younger students in research activities, because its introduction into the learning process stimulates the child's self-development mechanisms and turns learning into self-learning. It is clear that now the leading in educational institutions are teaching methods and techniques, which are based on a research approach, because in the developments of many outstanding teachers and psychologists it is indicated that the originality and criticality of thinking, the ability to interact, as well as the creative skills of young children are more fully defined and successfully develop in practice, especially on one that includes a research orientation. The article analyzes the concepts of "Internet service", "Information and communication technologies", the concept of the formation of research behavior of students in the lessons "I explore the world" by means of the Internet service Icograms 3D Map Designer in primary school, its advantages and disadvantages over other forms of methodological work. Characteristics of the possibilities of using the Icograms 3D Map Designer service in the subject "I explore the world" in primary school and methodological recommendations for organizing work using the Icograms 3D Map Designer service in the subject "I explore the world" in grade 2. A criterion has been developed and the level of preparation of a teacher for the use of the Internet service Icograms 3D Map Designer in the subject "I explore the world" is described. The use of the Internet service Icograms 3D Map Designer on the subject "I explore the world" allows the independent and collective creation of models, makes it possible to better understand the basic properties of objects, phenomena, processes, their studied components, the relationship between them. Their study forms students 'skills in analysis, synthesis, assessment, critical thinking, research skills, spatial thinking and imagination skills, and also provides feedback between participants in the educational process, increases the level of students' interest in the submitted educational material, provides an individual approach to each student. contributes to the high-quality organization of frontal, collective and group work, the implementation of constant monitoring and assessment of students' achievements.

The shape, latency and amplitude of changes in electrical brain activity related to a stimulus (Evoked Potential) depend both on the stimulus parameters and on the background EEG at the time of stimulation. An adaptive, learnable stimulation system is introduced, whereby the subject is stimulated (e.g. with light), whenever the EEG power is subthreshold and minimal. Additionally, the system is conceived in such a way that a certain number of stimuli could be given within a particular time interval. Related to this time criterion, the threshold specific for each subject is calculated at the beginning of the experiment (preprocessing) and adapted to the EEG power during the processing mode because of long-time fluctuations and trends in the EEG. The process of adaptation is directed by a table which contains the necessary correction numbers for the threshold. Experiences of the stimulation system are reflected in an automatic correction of this table. Because the corrected and improved table is stored after each experiment and is used as the starting table for the next experiment, the system >learns<. The system introduced here can be used both for evoked response studies and for alpha-feedback experiments.
