    The topic of the development of social economics in various countries of the world is becoming increasingly popular in modern scientific research due to both the novelty of the subject and its practical significance, especially in the context of modern challenges and threats. Studying the experience of functioning of social economy organizations in various countries of the world, it was concluded that the theoretical understanding and applied capabilities of this phenomenon (social economy) depend on its economic, institutional, cultural environment, and therefore the experience of developed countries is of interest. and developing. This article contains some results of the analysis of the potential of social economy for local development in the context of African countries, with the main theoretical hypotheses verified, and the conclusions demonstrated on the existing practices of social economy in the Federal Democratic Republic of Ethiopia, the culture and history of which is significantly different from other African countries. The work is structured in such a way that, firstly, some theoretical aspects of the social economy are clarified, secondly, the features of the social economy of Africa are described, thirdly, the forms of its existence are specified (organizational forms of social economy enterprises), their potential for the development of rural areas and communities in Ethiopia. In conclusion, a number of generalizations are presented for discussion by the scientific community regarding promising trajectories for the development of the social economy in Ethiopia (and in African countries in general), taking into account biological, climatic, and geopolitical limitations. The study was carried out using various review-theoretical and analytical research methods, including component, structural, comparative, as well as on the basis of institutional methodology tools popular in economic science.Тематика развития социальной экономики в различных странах мира становится всё более популярной в современных научных исследованиях в силу как новизны предмета, так и его практической значимости, особенно в условиях современных вызовов и угроз. Изучая опыт функционирования организаций социальной экономики в различных странах мира, был сделан вывод о том, что теоретическое понимание и прикладные возможности данного феномена (социальная экономика) зависят от его экономического, институционального, культурного окружения, в связи с чем интерес представляет опыт и развитых стран, и развивающихся. В данной статье содержатся некоторые результаты анализа потенциала социальной экономики для местного развития в контексте стран Африки, причём основные теоретические гипотезы верифицированы, а выводы продемонстрированы на имеющихся практиках социальной экономики в Федеративной Демократической Республике Эфиопия, культура и история которой существенно отличается от других африканских стран. Работа структурирована таким образом, что, во-первых, уточнены некоторые теоретические аспекты социальной экономики, во-вторых, описаны особенности социальной экономики Африки, в-третьих, специфицированы формы её существования (организационные формы предприятий социальной экономики), их потенциал для развития сельских территорий и сообществ в Эфиопии. В заключении для обсуждения научным сообществом представлен ряд обобщений, касающихся перспективных траекторий развития социальной экономики в Эфиопии (и в африканских странах в целом) с учётом ограничений биологического, климатического, геополитического характера. Исследование выполнено с применением различных обзорно-теоретических и аналитических методов, включая компонентный, структурный, компаративный, а также на базе популярных в экономической науке инструментов институциональной методологии

    Elastic resource management is anticipated to be prevalent in the forthcoming 6G, or 2030, networks. This approach entails not only adaptive allocation of resources but also the consideration of evolving service requirements, user behavior, and the dynamic state of the radio channel. One of the methods for distributing resources among network slices may not be equitable in terms of the required data transfer rates but aims for fairness concerning the data transmission delays. The paper formalizes the issue of resource allocation based on data transmission latency as a queuing system with a discriminatory processor-sharing discipline for classes of elastic traffic. The authors propose determining the discipline parameters - the weights for each class - according to the residual data transmission time. The fairness of resource allocation is evaluated using the Jain’s fairness index which is based on average transmission times.Ожидается, что в будущих сетях шестого поколения (6G), или сетях-2030, получит распространение эластичное управление ресурсами. Оно подразумевает не только адаптивное занятие ресурса, но и учет в настройке меняющихся потребностей в услугах и поведения пользователей и непрерывно изменяемого состояния канала связи. Один из вариантов разделения ресурса между сегментами сети - справедливое не относительно требуемой скорости передачи данных, а относительно задержки передачи данных. В статье формализована задача разделения ресурса по задержке передачи данных в виде системы массового обслуживания с дисциплиной дискриминаторного разделения процессора между классами эластичного трафика. Параметры дисциплины - веса каждого класса - предлагается выбирать, ориентируясь на остаточное время передачи данных, а справедливость разделения ресурса оценивать по индексу Джейна по среднему времени передачи

    L-asparaginase, which hydrolyzes asparagine and, to a lesser extent, glutamine, initially used to treat acute lymphoblastic leukemia and other hematological malignancies, may soon become a therapeutic agent for the treatment of a wide group of oncological diseases, as more and more evidence is accumulating that not only leukemia cells and lymphomas but also various solid tumors are sensitive to the action of this enzyme. However, like any other drug, L-asparaginase is not always effective; moreover, its use often leads to unwanted side reactions. Taking this into account, for the successful use of asparaginase, it is advisable to study and introduce into clinical practice prognostic markers that make it possible to predict in advance its effectiveness in the treatment of a particular patient. This review highlights various biochemical factors that influence the sensitivity of tumor cells to L-asparaginase. The asparagine synthetase and glutamine synthetase genes are examined in detail; the influence of their expression levels on the sensitivity of tumors to asparaginase has been studied in numerous experiments. In addition, “nonclassical” factors are considered, such as the expression of glutamine transporter genes, opioid receptors, methylation of the asparagine synthetase gene promoter, the activity of some signaling pathways, and the activity of the PTEN protein. The presented data can contribute to the creation of a more holistic and accurate system of markers that can be used to predict the sensitivity of tumor cells, including solid ones, to L-asparaginase

    Based on the experiments conducted by the authors, a concrete strength criteria has been developed, which allows us to take into account biaxial and triaxial states of stress in strength calculations of massive concrete and reinforced concrete structures. The developed strength criteria is adapted to a spatial eight-node finite element (solid type) and implemented in the PrinCe programme. In order to conduct the developed criteria operational check, both experimental data and calculation results of other widely used strength criteria for concrete were compared. Thus, to verify the proposed criteria under triaxial compression, the calculation results were compared with experimental data as well as with the Willam-Warnke criterion and the modified Drucker-Prager criterion. The comparison shows that in the low hydrostatic stresses mode results of the above criteria converge both with each other and with the experimental data. In the medium hydrostatic stress mode , the criteria proposed by the authors and the Willam-Warnke criterion show close results, while the modified Drucker-Prager criterion, on the contrary, gives 20 % overestimation of concrete strength. Comparison of the results of concrete biaxial tests shows good agreement with the criteria developed by the authors. Thus, for heavy coarse concrete the differences in strength values were not more than 3,5 %, for heavy fineconcrete and expanded clay concrete - not more than 4 %.На основании проведенных авторами экспериментов разработан критерий прочности бетона, позволяющий учитывать двух- и трехосное напряженное состояние при прочностных расчетах массивных бетонных и железобетонных конструкций. Разработанный критерий прочности адаптирован к пространственному восьмиузловому конечному элементу (сплошного типа) и реализован в программе ПРИНС. Для проверки разработанного критерия в работе проведено сравнение как с экспериментальными данными, так и с результатами расчетов по другим широко применяемым для бетонов критериям прочности. Таким образом, для проверки предлагаемого критерия в условиях трехосного сжатия результаты расчетов сравнивались с экспериментальными данными, а также с критерием Виллама-Варнке и модифицированным критерием Друкера-Прагера. Сравнение показывает, что в режиме низких гидростатических напряжений результаты по указанным критериям сходятся как между собой, так и с опытными данными. В режиме средних гидростатических напряжений предложенный авторами критерий и критерий Виллама-Варнке показывают близкие результаты, тогда как модифицированный критерий Друкера-Прагера, напротив, дает на 20 % завышенное значение прочности бетона. Сравнение результатов двухосных испытаний бетонов показывает хорошую согласованность с разработанным авторами критерием. Так, для тяжелых крупнозернистых бетонов расхождения в значениях прочности составили не более 3,5 %, для тяжелого мелкозернистого бетона и керамзитобетона - не более 4 %

    No full text
    Background. Blockchain technology is a decentralized, distributed ledger that is used to record transactions across a network of computers. The most common consensus mechanism used in blockchain networks is the Proof of Work (PoW) algorithm, which is used by networks such as Bitcoin and Ethereum. However, PoW is energy-intensive and can lead to centralization, which has led to the development of alternative consensus mechanisms such as Proof of Stake (PoS). Purpose. The objective of this study is to investigate the practical role of transitioning from the PoW algorithm to PoS in blockchain networks. This includes evaluating the benefits and drawbacks of PoS, assessing the costs associated with transitioning to PoS, and identifying any challenges or risks that may be encountered during the transition. Materials and Methods. This scoping review was conducted in accordance with the PRISMA-ScR recommendations for the search and selection of studies. The search was conducted on the popular scientific databases ResearchGate and IEEEXplore. The researchers found 237 articles on related topics and selected 42 of them. Studies published in English from January 1, 2014, ending to January 13, 2023, were viewed. Results. The results of this study indicate that transitioning from PoW to PoS can lead to significant energy savings and improved network performance. However, the transition also comes with certain challenges and risks, such as the need for significant upgrades to existing infrastructure and the potential for centralization. The survey results show that experts believe that PoS is a more sustainable and efficient consensus mechanism, but that more research is needed to fully understand its potential implications. Conclusion. The transition from PoW to PoS is a complex process that requires careful planning and execution. The results of this study suggest that PoS has the potential to offer significant benefits, but that there are also risks and challenges associated with the transition. Further research is needed to fully understand the implications of transitioning to PoS and to identify strategies for addressing the challenges and risks involved

    Knowledge of a foreign language cannot in itself guarantee the ability to communicate with clients in the hotel and tourism business independent from knowledge of intercultural differences. The figure of the teacher (preferably multilingual) comes to the fore. Despite the fact that teaching is moving to the student-centered learning, in terms of training specialists for the tourism industry, teacher-centered education remains no less important. As before, the intercultural competence of teachers and future specialists in the field of hospitality and tourism is extremely important.Знание иностранного языка не может само по себе гарантировать умение общаться с клиентами в сфере гостиничного и туристического бизнеса в отрыве от знаний межкультурных различий. Фигура преподавателя (предпочтительно, многоязычного) выходит на первый план. Несмотря на то, что преподавание переходит в плоскость student-centered, в плане подготовки специалистов для турбизнеса teacher-centered образование остается не менее важным. Как и прежде, крайне важна межкультурная компетенция педагога и будущих специалистов в области гостеприимства и туризма

    In today's world context, the existence and development of the policy communication system is identified as an important means in the entire policy cycle. Because it not only ensures that people are fully and accurately informed about what happened, but also supports social monitoring efforts on the policy implementation of public authorities. Based on an overview of some basic theoretical contents of policy communication, the article presents the role of policy communication in equality policy among ethnic groups in Vietnam and proposes some solutions to Improve the effectiveness of policy communication.В контексте современного мира существование и развитие системы политических коммуникаций считается важным инструментом всего политического цикла, включая политику равенства между этническими группами. Это не только гарантирует, что люди будут полностью и точно проинформированы о том, что произошло, что происходит и что произойдет, но также поддерживает усилия социального надзора по реализации государственной политики. Основываясь на обзоре некоторых основных теорий об политической коммуникации, в статье представлена роль политической коммуникации в политике межэтнического равенства между во Вьетнаме и предлагаются различные решения по повышению эффективности политической коммуникации
