Financial component of the hydrogen economy development strategy of Ukraine

The relevance of the study is determined by the need to detail the financial justification of the development of the hydrogen economy in Ukraine, taking into account the need to ensure energy independence and diversification of energy resources. With a sufficient number of publications on the innovativeness of hydrogen technologies, global trends in their use and the importance of decarbonization of public production, the issue of financial support for the development of the hydrogen economy remains insufficiently covered. The purpose of the article is to highlight and characterize the financial component of the strategy for building the hydrogen economy of Ukraine. To achieve the goal, general and special methods of scientific research were used: abstraction, decomposition, comparison, analysis, extrapolation. According to the results of the study, a derived relationship between the number of scientific studies on the development of hydrogen technologies and the state of the energy market was revealed, which made it possible to put forward a hypothesis about the intensity of research on the prospects for the development of the hydrogen economy in the context of the adequacy of its financing. The existing hydrogen technologies can be applied only in connection with the development of renewable energy, they require increased innovations in production, infrastructure, and consumption of hydrogen, therefore, they require increased financing. The financial component of the Hydrogen Strategy of Ukraine (until 2050), developed by the Ministry of Energy, is highlighted at each stage of its implementation. The foreign experience of strategies for the development of the hydrogen economy is presented and the insufficiency of financial resources to ensure the achievement of the target indicators of the Ukrainian strategy, especially in the conditions of war, is stated. The relationship between the Hydrogen Strategy of Ukraine and the Recovery Plan of Ukraine until 2032 is characterized. The general need for financing the development of the hydrogen economy at the second stage of the implementation of the Hydrogen Strategy was determined in connection with the content of the pilot projects. Accordingly, there is a need to detail the focus and sources of funding for the hydrogen economy development strategy in Ukraine, potential sources of cash receipts, changes in institutional and regulatory support for the hydrogen strategy.

Модель змагальної діяльності зв’язуючого гравця високої кваліфікації у волейболі

Increasing the competitive performance of Ukrainian volleyball players requires scientific support of the educational and training process and the use of modern methods of scientific research, one of which is modeling. Indicators of technical and tactical actions obtained by analyzing official competitions are the basis for creating models of competitive activity. The aim of the study is to develop a model of a high-skill link player on the basis of statistical data from the games of the Ukrainian Volleyball Championship among men's teams of the Super League. Material and Methods. The data of 18 qualified volleyball players who perform the function of a linking player in their teams were used for the study. We analyzed statistical data of link players of 8 teams participating in the Ukrainian Super League championship of the season 2023-24. To create a model of a linking player of Ukrainian Super League teams, 10 athletes were selected from the total sample, the main criterion was quantitative indicators of participation in the championship games (at least 80% of official matches). Research methods: analysis of literary sources and data in the Internet, pedagogical testing, analysis and generalization of statistical data of competitive activity, methods of mathematical statistics. Results. The analysis of game technical and tactical indicators of qualified volleyball players allows to understand more clearly the peculiarities of competitive activity of players of different roles. In accordance with the purpose of the study we analyzed the game activity indicators of linking players (number of matches and sets, total number of assists, effective assists, satisfactory assists, number of errors). It should be noted that all game indicators indicated the heterogeneity of the group of highly skilled binders, which is explained by different experience, players' participation in matches, and the variety of tactical actions of the teams. Conclusions. The developed model of competitive activity of highly skilled liaisons contains general data (height, age), indicators of physical abilities (height of block and attack), technical and tactical indicators (execution of passes, number of errors). In addition to the average data, the model presents a variation series from the lowest to the highest results.

Political PR in International Digital Communications: The Experience of the Eurasian Media Space

Digital media has become an integral part of the political life of citizens, as an increasing number of people around the world use digital media technologies for communication. Digital media contribute to the formation of socio-political factors that raise concerns about the spread of disinformation, information disagreements and political polarization.Aim. To analyze the tools, problems and opportunities of political PR in the context of digitalization of the media space in foreign countries and the EAEU countries.Tasks. To give significant ideas about the concepts of “political public relations” and “political communication”; to identify factors influencing political communication processes; to present international experience in the application of political PR in the context of digitalization of media; to formulate the possibilities for the development of Eurasian integration in the context of digitalization of the media space.Methods. The methodological basis of the scientific research was such modern general scientific research methods as: comparative analysis, statistical and structural-logical methods, content analysis of open sources of information.Results. The paper defines the role and importance of digital media in political PR activities, identifies traditional and modern factors of influence on political activity, as well as problems in the new digital reality. To build political communications with the audience, its impact and increase engagement, political organizations use new media technologies using multimodality. In practice, the digital inequality of the world population deprives a number of people of digital communication, and as a result, the necessary conditions for participation in the political and economic life of the country. The digital divide of the EAEU countries reduces the political communicative impact on citizens’ beliefs in the need to strengthen integration processes. It seems appropriate to introduce consistency in the formation of the Eurasian integration agenda and a single digital information field to increase the political culture of civic engagement in all EAEU member states.Conclusions. With the help of variation of resources, the necessary content is formed to create the necessary audience effect. Indeed, digital media has a number of advantages that have been proven in practice, however, political PR is influenced by the negative side of the development of digital communications — the spread of fake news, most of which cannot be traced to the source. Therefore, the transformation of digital opportunities, the distribution of political resources, the dissemination of political discourse and the structure of political opportunities in the digital age is the most relevant in the modern world. Using the example of the EAEU countries, it is proved that digitalization in the international media space causes the involvement of citizens of different countries in integration, generalization and formation of public support for the state.

A Portfolio Management Method for Process Mining-Enabled Business Process Improvement Projects

AbstractProcess mining has received tremendous attention from research and industry, establishing itself as a highly sought-after technology. Despite the technological maturity of process mining solutions, which has been achieved through extensive investments in research and development, organizations still face the challenge of elusive value when systematically adopting process mining. The authors attribute this dilemma to a lack of support for scaling and managing process mining project portfolios. To address this practical need and research gap, the authors propose a method for managing portfolios of so-called process mining value cases, which are defined as process mining-enabled business process improvement projects, towards an evolutionary roadmap (mapper). The method is designed to support organizations identify portfolios of process mining projects that generate value by improving business processes. The method was developed through a combination of design science research and situational method engineering and comprises five activities that each outline techniques, roles, and tools: strategize, identify, select, implement, and monitor. The method has been instantiated as a software prototype and iteratively evaluated for applicability and real-world fidelity by involving an expert panel of academics and practitioners. The usefulness of the artifact was substantiated through a real-world case study in a naturalistic setting.

A methodology to assess indicators of technological development of the industry: The electronics industry case

The focus is on development and testing of a methodology for evaluating indicators of technological development of the industry. Methods. The study rests on general scientific principles and research methods, like abstraction, generalization of approaches to industry’s technological development assessment, analysis, synthesis, systematization, and generalization of obtained results. Results. The developed methodology includes five stages: (1) assessment of preconditions for technological level change; (2) analysis of intensity of modernization; (3) analysis of staff development, growth of labor productivity and remuneration level; (4) assessment of innovation activity; (5) analysis of consequences of changes in the technological level as an increase in value added, return on capital, and sustainable growth. Conclusions. I tested the methodology on data from a sample of electronic industry enterprises (OKVED 26 Manufacture of Computer, Electronic and Optical Products). Calculations show that there are evolutionary, but not large–scale changes. However, there are no signs of noticeable innovative development. At the same time, there are significant changes in individual companies, like PAO Element, controlled by State Corporation Rostec Group. The analysis of the company's consolidated financial statements showed a significant inflow of resources, an increase in investment and innovation activity, staff development, an increase in value added, return on capital, and accelerated growth.

REFLECTION IN THE STRUCTURE OF INNOVATIVE COMPETENCE OF TEACHERS IN GENERAL SECONDARY EDUCATION INSTITUTIONS

The issue of the article concerns the topical issue of innovative competence and its components. The author aimed to characterize one of the components of this education, which refers to the ability to analyze the effectiveness and efficiency of pedagogical activity, as well as to adjust it as necessary. It is about the skill of reflection as one of the leading features of a teacher with highly developed innovative competence, since the creation and implementation of innovations requires regular analysis not only of the process of implementing something new in the educational process but also of observing and evaluating the personality of the teacher as a specialist who carries out innovative activities. Thanks to the use of such methods of scientific research as system-structural and system-functional analysis, generalization and systematization of theoretical aspects of the topic, observation, and study of the products of pedagogical activity, the author conducted a review of scientific literature regarding the essence of innovative competence of a teacher of a general secondary education institution, its structure and key characteristics, in particular, reflection skills. In addition, the publication provides information on reflective competence, which, on the same level as innovative competence, occupies a prominent place in the system of professional characteristics of a teacher regulated by normative documents. The unifying feature for both is the skill of reflection, therefore the article also presents the views of domestic scientists on the essence of this phenomenon and methods of its development and improvement. In addition, practical tools (reflective questionnaires, tables; reflective essays; pedagogical portfolios, etc.) are characterized, which contribute to the formation and improvement of the ability to reflect on one's pedagogical activity, in particular innovative ones. The publication analyzes fragments of reflective essays from teachers of general secondary education institutions who took the experimental course "Innovative aspects of the teacher's activity". This made it possible to conclude the reflexive competence of teachers, the development of reflection skills, as well as to substantiate reflection as a component of innovative competence.

Motion Recognition Based on Deep Learning Algorithm

Advanced scientific and technological measurement methods are the basis of sports research and the progress of sports research methods. It promotes the continuous improvement of sports technology to meet athletes’ pursuit of excellent sports achievements. Therefore, the method of sports scientific research must be changed from the traditional empirical training mode to the programmed training method, from the qualitative analysis of the training effect to the nuanced analysis of the training process. Based on this, this paper uses in-depth learning to study sports motion capture. First, two-dimensional human joints are extracted based on Mask R-CNN. Then, the 3D human motion skeleton is constructed by using the binocular vision system, and the Mask R-CNN human pose estimation algorithm is optimized. On this basis, a sports motion capture system is designed, and the system’s accuracy is verified. The error of the depth information obtained by the sports capture system constructed in this paper is less than 3% in the experiment of about 2[Formula: see text]m. It has strong practicability.

9.Q. Round table: Strengthening public health law for public health professionals

Abstract Law is a tool that public health experts can use to improve population health. Generally, law offers a range of opportunities: it can encourage healthy and safe behaviours; it can change and shape the physical and social environments; influence the social determinants of health, as well as structure the public health system. Law can also compel or restrict, and legal systems can provide accountability and oversight. ‘Public health law’ stands at the intersection of public health and law, and offers a range of powerful tools for improving health (Burris et al, 2018). While public health law is an important field for public health professionals, there is a lack of knowledge about this field, and a lack of interaction between public health professionals and law professionals. There is also a need to understand the ways law might challenge public health goals. For example, law can be used to promote goals which do not improve public health, or public health concerns can be sidelined, and law can be a tool for challenging specific public health interventions. The focus of this roundtable will be on identifying and building necessary capacities for using law by public health professionals. End-goal is to identify new initiatives to consolidate and to strengthen public health law as an important field for public health professionals. To achieve these aims, we have set three practical steps for the roundtable to embark on: 1) strengthening collaboration; 2) identifying knowledge gaps and opportunities; and 3) starting new initiatives: 1) Strengthening the collaboration and building new partnerships: we bring together experts from law and public health to identify the gaps and opportunities when it comes to implementing law by public health professionals. The roundtable will foster new collaborations and partnerships between law and public health professionals. 2) Identifying gaps and opportunities: there is a need to identify deficiencies in health policy research and how to use scientific legal research methods to overcome these problems. Relatedly, to share experiences and best practices when it comes to teaching public health law. Opportunities include the transdisciplinary model and legal epidemiology; a focus on the commercial determinants; and applying a human rights lens. Panelists - in an interaction with the audience - will identify key opportunities and discuss ways to implement them. 3) Starting new initiatives: panelists will be asked to concretize existing initiatives and discuss with the audience how they can be integrated in the field, based on our new partnerships. New collaborations will be identified. This may vary from building a new network, applying for a joint research grant or for strengthening or complementing existing teaching modules. Altogether, this roundtable aims to strengthen our understanding of existing efforts and of the various ways in which public health expertise can be integrated in better law making. Key messages • Drafting of sound laws that improve health is a joint practice of various professionals, including legal and public health professionals. • We need to strengthen existing capacities and build new ones for using law by public health professionals.

Co-developing frameworks towards environmentally directed pharmaceutical prescribing in Scotland – A mixed methods study

The presence of human pharmaceuticals in the aquatic environment is recognised internationally as an important public health and environmental issue. In Scotland, healthcare sustainability targets call for improvements to medicine prescribing and use to reduce healthcare's impact on the environment. This proof-of-concept study aimed to develop a framework on the environmental impact of pharmaceuticals to use as a knowledge support tool for healthcare professionals, focussing on pharmaceutical pollution. Nominal Group Technique was applied to achieve consensus on pharmaceuticals and modelling factors for the framework, working with a panel of cross-sector stakeholders. Bayesian Belief Network modelling was applied to predict the environmental impact (calculated from hazard and exposure factors) of selected pharmaceuticals, with Scotland-wide mapping for visualisation in freshwater catchments. The model calculated the pollution risk score of the individual pharmaceuticals, using the ratio of prescribed mass vs. mass that would not exceed the predicted no-effect concentration in the freshwater environment. The pharmaceuticals exhibited different risk patterns, and spatial variation of risk was evident (generally related to population density), with the most catchments predicted to exceed the pollution risk score for clarithromycin (probability >80 % in 35 of 40 modelled catchments). Simulated risk scores were compared against observed risk calculated as the ratio of measured environmental concentrations from national regulatory and research monitoring and predicted no-effect concentrations. The model generally overpredicted risk, likely due to missing factors (e.g. solid-phase sorption, temporal variation), low spatial resolution, and low temporal resolution of the monitoring data. This work demonstrates a novel, trans-disciplinary approach to develop tools aiding collation and integration of environmental information into healthcare decision-making, through application of public health, environmental science, and health services research methods. Future work will refine the framework with additional clinical and environmental factors to improve model performance, and develop electronic interfaces to communicate environmental information to healthcare professionals.

Identifying Tools and Techniques for Picking out Cultural Bottlenecks: Another Crucial Component of the Symbiotic Approach to Socio-Cultural Change

This paper is built upon our earlier papers on the symbiotic approach to sociocultural change, and extends them meaningfully in new directions. This is done by proposing different types of tools and techniques that can be used in identifying cultural bottlenecks, and can therefore be used to usher in, or bring about a faster pace of sociocultural change. We therefore, aptly and appropriately begin this paper by carrying out a brief overview of our earlier papers on sociocultural change, and by briefly laying down their various concepts and postulates. Subsequently, and resultantly, various tools and techniques for identifying and overcoming cultural bottlenecks are also proposed. These include an alignment with a cultural taxonomy, a comparative method to compare cultures, a high low analysis of values, a root cause analysis of cultural performance, analysis of cultural orientations, an evaluation of cultural performance by laying down metric and measurements and analyzing the pace of sociocultural change, etc. We also briefly discuss ethnographic techniques that can be used to evaluate cultures, including long-term ethnography and the ethnography of enculturation. Likewise, social science research methods, and components of research design are reviewed, besides some other approaches to identifying and analyzing cultural bottlenecks. We hope and anticipate that this paper will become a useful cog in the machine to bring about faster sociocultural change, and will become an intrinsic part of our globalization of science movement as well.

Impact of International Law Fragmentation on the Development of Integration Processes

This article analyzes the relationship between the phenomenon of fragmentation of international law and integration processes aimed the modern global transformations. Various approaches to understanding the fragmentation of international law are considered, including its causes, forms, and consequences. The article examines how fragmentation impacts the functioning of international integration entities, the development of interstate relations, and the effectiveness of international legal regulation. Particular emphasis is placed on the role of fragmentation as a conducive factor for the advancement of international integration and the establishment of specialized legal regimes within integration associations. Consequently, the degree of fragmentation in international law within established regions correlates with the level and depth of integration. In the current context, the fragmentation serves as a favorable element for participating states in fostering their integration interactions. In addition, international law functions as a crucial instrument for regulating these integration processes. The methodological foundation of this article comprises well-established general and specific methods of scientific research. The article’s purpose and objectives are to investigate the degree of influence and the nature of the interaction between the fragmentation of international law and modern international integration processes.

Глобальні виклики для систем соціальної підтримки: сутність, компонентні ознаки та особливості

The article is devoted to issues of global challenges for social support systems. The relevance of the study is determined by the growing role of global challenges in the socio-economic life of states. The purpose of the article is to analyze the specifics of global challenges characterizing modern social support systems, including the social support system of Ukraine. The scientific novelty of the article lies in the identification of global challenges for social support systems. The basic methods of scientific research used in the article are analysis and synthesis (to identify the specifics of global challenges for social support systems), graphic method (to demonstrate the connection between the global basis of the emergence of global challenges and challenges for the social support system). It has been established that the main global challenges for social support systems are the following: the functional failure of the social support system; growing needs of recipients of social services, benefits, and payments; the transformation of a socially oriented state; the reduction in abilities of states to maintain social support systems. The functional failure of the social support system means its state in which the formal presence of agencies and institutions designed to guarantee the provision of social services, benefits and payments to the population is not accompanied by their effective work, that is, the system of social support does not solve the current social problems of society and becomes a burden for state budget. The most acute challenge for the social support system for Ukraine under war conditions is the growth in the needs of recipients of social services, benefits, and payments, which can occur in two ways: 1) an increase in the needs of existing recipients of social benefits, services, and payments on account of changes in the socio-economic, political, ecological, security situation in the region or objective physiological changes in certain groups of recipients (aging, deterioration of well-being); 2) an increase in the number (or share) of people applying for social support due to changes in the socio-economic, political, environmental, security situation in the region or subjective life circumstances. Closely related to this challenge is another challenge, namely the reduction in states’ ability to maintain social support systems. Particular attention is paid to the causes and potential consequences of the transformation of the concept of a socially oriented state. In addition, the author researched the global basis of challenges for social support systems, which combines the key factors of their occurrence.

Income level as a differentiating factor in assessing the impact of migration on economic growth

Aim. To study the nature of the impact of migration on economic growth depending on the level of gross domestic product (GDP) per capita and the direction of migration flows.Objectives. Study of theoretical approaches to the research of the impact of labor migration on economic growth; analysis of factors that differentiate the assessment of the impact of migration flows on economic growth indicators; collection and analysis of statistical information for the development of econometric models for assessing the impact of migration on economic growth.Methods. The authors used general scientific methods of research, such as deduction, analysis, synthesis. Statistical methods of data analysis were applied, linear regression models were built.Results. The research shows that the impact of migration on economic growth in countries with different levels of GDP per capita is due to different factors. For developed economies, the positive factors of the impact of immigration on economic growth are replenishment of scarce labor resources; improvement of labor force quality due to structural changes caused by the transition of the permanent working-age population to new professional fields. For countries with a low level of GDP per capita we can identify a number of positive factors of the impact of emigration (with a negative balance of migration growth) on economic growth. In particular, the outflow of excess labor force creates conditions for reducing unemployment; remittances of migrants support effective demand in the consumer market, contribute to the development of the banking system and investment in the country of origin; the expansion of social ties leads to the development of human capital, increasing the potential for innovation.Conclusions. The value of correlation coefficients in the constructed regression models indicates that there is a weak correlation between the variable characterizing the volume and nature of migration in the country (the ratio of migration balance to population) and the variable characterizing economic growth (GDP per capita at purchasing power parity) only for the group of high-income countries. There is little statistical dependence of these variables for other groups of countries. With regard to econometric modeling of the impact of migration on economic growth, this means that it is necessary to develop separate models for each group of countries depending on the level of GDP per capita and the direction of migration flows.
