Multilayer event‐based distributed control system for DC microgrids with non‐uniform delays and directional communication

The secondary control layer of microgrids is often modelled as a multi-agent distributed system, coordinated based on consensus protocols. Convergence time of consensus algorithm significantly affects transient stability of microgrids, due to changes in communication topology, switching of distributed generations (DGs), and uncertainty of intermittent energy sources. To minimise convergence time in consensus protocol, this work proposes a multilayer event-based consensus control framework, which is resilient to communication delays and supports plug-and-play (P&P) addition or removal of DGs in DC microgrids of cellular energy systems. A novel bi-layer optimisation algorithm minimises convergence time by selecting an optimal communication topology graph and then adjusts controllers' parameters. Average consensus is achieved among distributed controllers using an event-based consensus protocol, considering non-uniform delays between agents. A realisation method has also been introduced using the directional beamforming technique for topology assignment algorithm based on modern telecommunication technologies. Provided feasibility case study has been implemented on a real-time hardware-in-the-loop (HIL) experimental testbed, to validate the performance of the proposed framework for key purposes of voltage stabilisation and balanced power-sharing in DC microgrids.

The nexus between urbanization and rural development in China: Evidence from panel data analysis

AbstractAs rural decline sweeps the world and draws public attention, it becomes necessary to consider the relationship between urbanization and rural development. The paper investigates this topic in China for the period 1989–2018. The research results find positive contribution of urbanization to rural economy in the research period but with a decreasing tendency. Compared to less developed areas, rural economy of developed regions has become less dependent on cities and can flourish in a larger context with the support of modern transportation and telecommunication technologies. However, those peripheral rural areas tend to face continuous and large‐scale rural–urban migration which has aggravated rural decline. Rural economic growth helps to decrease rural outmigration and people will stay in their hometown with available job opportunities to raise their families and maintain livelihood. The paper proposes balance‐friendly urbanization structure and diversified rural economy to improve rural resilience to meet the challenge of rural decline.

INTRODUCTION OF INTERNET TECHNOLOGIES IN THE EDUCATIONAL PROCESS OF HIGHER EDUCATION INSTITUTIONS

The article considers the ways of introduction of Internet technologies in the educational process of higher education institution. The principles of building computer training centers based on network technologies are highlighted: versatility, accessibility, use of standard network solutions and building a system based on a universal integrated database that allows you to easily and virtually unlimitedly build, transfer and scale it. Based on these principles, you can build a prototype of the Internet distance learning system, which allows you to create courses in technical, humanities and other disciplines. The technology of distance learning is described, which provides the educational process based on the use of modern information and telecommunication technologies. The conditions of efficiency and quality of teaching of students by means of distance learning are determined: favorable conditions for growth of activity of students by selection of means of training taking into account specificity of their individual cognitive properties are created; effective means of support of individual and group forms of training are used; the experimental-research basis of the educational process is expanding; the gap between the existing content of education and the achieved level of development of modern science is reduced. Peculiarities and advantages of using distance learning of students in comparison with traditional forms (full-time and part-time) are highlighted. It was found that the tutorial is one of the main components of the educational process in distance learning, which uses a set of methods and approaches to learning focused on the needs of students. The article states that one of the distance learning systems is the Moodle system, which is designed to organize online learning in a networked environment using Internet technologies.Keywords: Internet technologies, distance learning, Case technology, TV technology, Network technology, tutorial, higher education institutions, Moodle distance learning system.

Problems of digital transformation of film distribution

The article provides a brief overview of the emergence of the legal market of online cinemas in Russia. The paper reveals that the Governments of many countries have a national policy that is aimed at maintaining internal programming on traditional video platforms. Such policies range from licensing, which requires serving the “public interest” and defines rules for the distribution of certain types of content produced domestically, to requiring content distributors to contribute to the financing of the production of domestic content. The authors investigate that during the implementation of these rules, the Russian government decided on the allocation of limited resources. There was also regulation on whether platforms can solely decide what content to offer their users, or whether viewers should also participate directly. The study concludes that the transition from traditional platforms to online distribution can reduce the effectiveness of existing regulatory regimes and deprive traditional platforms of audience and revenue.The world and Russian experiences of using the Internet prove that today modern information and telecommunications technologies can contain real threats to the violation of fundamental rights and freedoms of citizens, as well as to question the security of society and the state. The only exceptions are progressive or innovative areas related to the provision of new services and the expansion of opportunities for socio-economic development.As a result of the study, the paper identified four problems of Russian film distribution on digital platforms. The authors chose piracy as the first problem of online cinemas. Pirate sites not only illegally copy content from online movie theaters, but they also create copies of their own services to transfer their servers to another platform in case of blocking. The second problem was highlighted by the requirement for foreign owners. The third problem was highlighted by the high cost of online movie theater subscriptions. The authors consider the fourth problem the lack of financial support from the state.

ОСОБЛИВОСТІ ДИСТАНЦІЙНОГО НАВЧАННЯ У ВИЩІЙ ОСВІТІ В УМОВАХ ПАНДЕМІЇ COVID-19

Today, the system of higher education around the world continues to take measures to effectively organize educational activities in the context of the COVID-19 pandemic. All METHODS OF TEACHING AT HIGHER EDUCATIONAL ESTABLISHMENTS Issue I (81), 2021 131 countries of the world had to face unexpected difficulties in connection with the introduction of self-isolation. The higher education system was "on the front lines" with a large number of people. The closure of higher education institutions and the emergency transition to distance learning have led to obvious problems, mainly due to insufficient technical equipment, lack or poor preparation of both teachers and students to work in the new environment. These and other problems pose another challenge to the higher education system in a critical situation. At the same time, along with the obvious challenges and problems, the new format of distance learning provides a wide range of opportunities and prospects for change and improvement of educational systems, for which the critical situation creates forced conditions. The article substantiates the importance of effective distance learning in higher education in the context of the COVID-19 pandemic and outlines the main problems of the individual in the relationship "teacher-student" in quarantine. The current stage of informatization of society cannot be imagined without the introduction of information and communication technologies in all parts of the education system, educational institutions and government. These technologies are especially relevant in quarantine, as they allow you to implement distance learning. It is also important that distance education expands and renews the role of the teacher, makes him a mentor-consultant who should coordinate the cognitive process, constantly improve the courses he teaches, and increase creativity and skills in accordance with innovations and innovations. During distance education, there is also a positive impact on higher education: increasing their creative and intellectual potential through self-organization, the desire for knowledge, the use of modern information and telecommunications technologies, the ability to make responsible decisions. The analysis of the research devoted to distance educational process, has allowed to reveal its other basic features, in particular: orientation on independent cognitive activity; significant potential opportunities for distance learning to intensify educational and cognitive activities; the possibility of organizing open learning, expanding the audience of consumers of educational services; integration of world educational services; reduction, under certain conditions, of material costs for the organization and implementation of the learning process.

Інформаційна етика як необхідний елемент регуляції сучасного інформаційного суспільства

The article is devoted to the analysis of the importance of information ethics in the active development of information and communication technologies. Active research on the issues of cyberspace has been conducted since the second half of the ХХth century. These studies are becoming more intensive every year. Many scientists are interested in analysis of these issues because communication plays the fundamental role in our dynamic modern world. Modern telecommunication technologies and, first of all, the global Internet, are one of the most important factors in the development of the world community, which has a decisive influence on the social, political, economic and socio-cultural spheres. And the global pandemic Covid-19 since 2020 has brought these issues to the forefront of socio-humanitarian research. The information space of the Internet, which has already become the main infrastructure of social communication at the local and global levels, is a relatively new cultural phenomenon. It is obvious that a clear and effective system of moral regulation in this area has not yet developed. This space provides a person with unprecedented opportunities in terms of personal freedom, challenging traditional moral attitudes. Of course, this raises many ethical issues, both general and applied, related to the spread of coercive and aggressive Internet advertising, pornography, violence, intrusion, privacy, and many other aspects. Computer technologies are not neutral. They are filled with human, cultural and social values. These values can be predicted and taken into account, they can appear and evolve after many trials and errors. In our multicultural world conflicting value system can often arise. Future research needs to do as much as possible to create a broader and more promising concept of what it means to be human in the stream of transformations that exist today. The solution of certain problems in information ethics is different depending on who solves these problems. All dilemmas and problems within the framework of the considered direction of applied ethics are open, and no one can give an exact answer to the questions yet. Thus, since in the modern information society there is a direct relationship between the intensity of technological development and the growth of crises in the field of moral values and spiritual culture, information ethics already makes a serious claim to the moral regulation of human behaviour.

THE PECULIARITIES OF EDUCATIONAL COMMUNICATION UNDER THE DISTANCE LEARNING MODE

The article analyzes the features of educational communication in higher education institutions in the context of distance learning. It has been noted that the ultimate goal of educational communication is both the transfer of information and the formation of a certain system of students’ knowledge, skills and competencies . The objective of the article is to analyze the features of the model of educational communication as a classic element of the information and pedagogical environment in terms of distance learning on the basis of pedagogical constructivism, presented in modern domestic and foreign studies. It has been analyzed the concept of distance learning as a purposeful interactive process of higher education, based on scientific sources and the use of modern information and telecommunications technologies. The advantages of distance learning are emphasized, in particular extraterritoriality, synchronous and asynchronous modes of interaction of participants of educational process. Under the distance learning mode there is a practical mastering of information tools and communication technologies. It has been emphasized that distance learning provides access to various educational resources, gives an opportunity to receive education in a convenient, adequate and appropriate form for the student, helps to develop student abilities, provides data exchange, communicative activities based on professional and educational interests, training, retraining or change professional activity. The educational environment as a combination of offline and online structures in monocultural and multicultural space is studied. It is emphasized that with the development of information technologies the students’ communicative efficiency of increases, access to international resources is simplified. The change of the model of educational communication is substantiated, as a result of which there is an attraction of more sources of information and communication channels in the space of information flows. It has been made the conclusions about the change of information transfer technology in a modern higher education institution. The communication capabilities of the educational process in terms of distance learning depend on the means of transmitting information that meet the goals and objectives of learning. Changes in the regulation of educational communication, the modality of the learning process is to assess the information educational flow by the subject of learning in solving personal educational problems.

Methodological Considerations for Amish-Focused Opinion Research: Lessons from a Study of Beliefs and Practices about Agriculture and the Environment

Certain aspects of Amish agriculture have been studied extensively but much is still unknown about Amish environmental attitudes and beliefs. This is due, in part, to the difficulty of directly soliciting responses from adherents. This article—part of a larger study of the Kishacoquillas Valley Amish settlement in Mifflin County, Pennsylvania—reflects on methodological challenges that arose during a study on Amish environmental attitudes and behaviors. Farmers from two Amish groups, as well as two non-Amish groups used for comparison, were interviewed about their environmental attitudes. Recruiting Amish participants for interviews was difficult due to the limited use of modern telecommunications technology, what can be perceived as a general suspicion of non-members, and concerns about possible publicity. Further, the use of standard academic research method protocols and survey instruments proved challenging with the Amish. Administering an academic-level survey to the Amish, a group whose formal schooling generally ends at eighth grade and whose first language is Pennsylvania Dutch, posed challenges for the interviewees’ understanding of certain technical terms and for the interviewer’s interpretation of responses. As the study unfolded, methodological flexibility was necessary to adapt the research to the people. Namely, open-ended questions were added to the formal survey in order to learn more about Amish attitudes about stewardship. These study reflections suggest that researchers should take time to learn about the local context and culture and be flexible in selecting and adapting methodological instruments.

Information fatigue syndrome as a consequence of global transformation processes

The development of new forms of cooperation between the state and citizens within the framework of the general digitalization of public administration, due to the radical restructuring of state-public interaction, taking into account compliance with the realities and new challenges that arise on the way of introducing modern information and telecommunication technologies in all spheres of public life, is characterized by several positive shifts in this area. In particular, the activities of public administration and local self-government bodies are becoming more open, transparent, as understandable as possible, and close to the usual everyday needs of individuals. However, these processes do not always allow achieving the desired effect, because they can be accompanied by a lack of constructive dialogue between the subjects and objects of management, rejection of the new realities of functioning and resistance to social changes, some negative manifestations caused by the latest social reality. At the same time, we would like to note that without exception, all stages of the historical development of mankind at the stage of their transition from one to another brought with them significant qualitative and quantitative changes in all spheres of social life, including social, every day, political, cultural and spiritual and the like, characterized by both positive shifts and negative phenomena.

Electronic court proceedings are now becoming a prerequisite for the effective functioning of the entire judicial system. The introduction of digital technologies in the judicial process is one of the tasks of reform, and its speed, cost-effectiveness and accessibility depend on it. The research purpose of this article is to identify common positive and negative features of the process of integrating modern technologies into civil proceedings in Indonesia, Thailand, and Malaysia. It is proved that: 1) Legal regulation of application of technical means in civil proceedings are not often in line with modern realities; 2) It is necessary to create conditions to secure judicial form of protection of rights and lawful interests by means of digital technologies; 3) The judicial form of protection of rights online is a guarantee of its implementation; 4) Implementation of procedural actions with the help of digital technical means needs simplification; 5) The general trend in reforming the civil process is wider application of artificial intelligence technologies. Comparative legal analysis of foreign legislation and literature demonstrates different levels of e-justice achievement in the countries under study, among which Malaysia is a leader in integrating modern information and telecommunications technology in civil proceedings; 6) The level of implementation of the digital agenda varies depending on the type of legal proceedings.

Дистанційна форма навчання студентів-медиків як виклик сьогодення

A year has passed since humanity first encountered a previously unknown disease — COVID-19, which changed and made adjustments to the established mechanisms of human life. These changes also apply to the field of education, including medical education. Due to the quarantine imposed in Ukraine to prevent the spread of COVID-19, educational institutions were closed and students were transferred to distance learning. Organize quality online learning in a short period of time, charge motivation to learn and be prepared for technological problems — this is not a complete list of problems faced by teachers. However, the present can be called the era of computer science, telecommunications and global digitalization. The rapid rise of the integration of information and communication technologies, online tools in society in recent decades has become a preparation for solving problems and problems. Distance learning has advantages and disadvantages. In addition, there are several organizational and methodological and organizational and technical models of distance learning. Practical classes on pediatric therapeutic dentistry are held in the format of an online conference in the Microsoft Teams program (Pre-created Classes for each subgroup and events in the program — in the calendar according to the schedule, students are invited). Microsoft Teams is a teamroom for Office 365, which is a simplified version of learning management systems, but allows the learning team to communicate and share files. The program is convenient because it combines everything in a common work environment, which includes chat for discussion, file sharing and corporate programs. Students take each test topic in the system according to the calendar-thematic plan, get the result, which the teacher converts into points, according to the evaluation criteria. During the online lesson, the teacher interviews the topic, corrects the answer, explains the points that were unclear, using pre-loaded materials — presentations, videos, photos, radiographs and orthopantomograms, which helps to master the material. For future dentists, practical training, work with real patients, practice of manual and communication skills are extremely important, so during the remote teaching of pediatric therapeutic dentistry, situational problems are solved and algorithms of practical skills are analyzed in order to bring students closer to practice. Distance learning is a purposeful process of interaction between teacher and student, based on the use of modern information and telecommunications technologies that allow distance learning, which is relevant in a pandemic COVID-19. No conflict of interest was declared by the author. Key words: distance learning, medical education, teacher, student, COVID-19 pandemic.

Telematics – electronic data interchange / EDI / in port transport logistics

ABSTRACT The logistics and distribution function of ports includes various services, mainly circulation and optimisation, leading to minimising logistics costs and rationalising the distribution of goods during their flow from sender to recipient. The implementation of this function in many ports has become an opportunity for their activation and development, in recent years the demand for distribution services has clearly increased, seaports as part of transport chains are the most favourable place to locate such services. The functioning of these centres is now ensured by modern information and telecommunications technologies, whose combined application to move people and loads in geographical space has created a new field of science and practice, generally known as transport telematics. Previous scientific, implementation and experience research in the introduction and application of telematics technologies, i.e. the joint application of information and telecommunications technologies, has enabled the construction of numerous telematics systems, including in transport. It can therefore be concluded that telematics systems are technology innovations, and their functioning is ensured by the electronic exchange of EDI data, whose place and role in transport is indicated by the content of this article.

Social networks as a basis for interaction between authorities and non-profit organizations established on the basis of nationality in public communications space

The article is devoted to the discussion of the influence of modern information and telecommunication technologies on the process of building bilateral communication of state and municipal administration bodies with non-profit organizations created on the basis of national origin from the point of view of the management of public values and the stakeholder approach. The purpose of this article is to analyse the possibilities of organizing social and network interaction between the authorities and representatives of non-profit organizations as an institutionalized form of existence of national communities and faiths (on the example of social and network space of public communications of the Central Federal District). In the course of the study it was found that in the sphere of interethnic and interethnic relations the most relevant is the formation of a specialized single social and network resource in the information and communication space of the region. The preferred format of using such a resource, according to experts, should be related to the questions of obtaining information on decisions made by the authority and their subsequent discussion. At the same time, experts underestimate the possibilities of organizing dialogue and partnership on the basis of social media. At the same time, an analysis of existing social media practices has shown 1) a small proportion of accounts of state structures, which are responsible for interaction with representatives of national associations and diasporas; 2) the mismatch distribution in the social and network space of public communications pages of the authorities of the subject of the Russian Federation, carrying out in their activities interaction with national NGOs, accounts of non-profit organizations themselves, created on the basis of national origin, as well as representatives of national communities and diasporas. These circumstances allowed the authors to make a conclusion that it is necessary to establish in social networks systematic work of the authorities of the constituent entities of the Russian Federation with non-profit organizations, which represent national diasporas and communities on the territory of the regions of the Central Federal District.

City railways – who are their passengers?
