ВОРОГИ, СУСІДИ, СОРАТНИКИ: «ЄВРЕЙСЬКА ТЕМА» В УКРАЇНСЬКІЙ ЛІТЕРАТУРІ МЕЖІ XIX–XX СТОЛІТЬ
Authors: Назаренко Михайло
Published: April 2023

Проблеми українсько-єврейських культурних стосунків наприкінці старого віку та єврейська тема- тика в українській літературі неодноразово обговорювалися (наприклад, у працях Джорджа Ґрабовича, Мирослава Шкандрія, Йоханана Петровського-Штерна). Пропонована стаття має на меті дослідження того, як на межі ХІХ–ХХ століть в українській літературі змінювався образ єврея / євреїв / єврейської спільноти, переважно на матеріалі текстів, написаних на підросійській Україні, що їх не розглядали наші попередники. Окрему увагу присвячено поглядам Лесі Українки, оскільки в тодішній культурно-суспільній ситуації вона значною мірою була винятком.

Вже в часи романтизму в поезії Тараса Шевченка та Миколи Костомарова виникають паралелі між старозаповіт- ними євреями та українцями як жертвами імперій, проте в літературі середини XIX століття, яка зображувала сучас- ність, домінував романтичний антисемітизм, спертий на фольклорні стереотипи. Він перейшов і в літературу реалізму, й лише в 1880–90-ті роки уявлення про євреїв як народ, в принципі ворожий українцям, поступилося місцем новим, більш об’єктивним моделям. Стосунки двох народів вже розглядалися не в фольклорно-етнографічній, а в соціокуль- турній площині. Показово, що ці зміни почалися після погромів 1880-х років, але не набули помітного характеру аж до революції 1905 року.

Ідея українсько-єврейської антиімперської співпраці була сформульована не пізніше 1890-х років (Іван Нечуй- Левицький) і пропагувалася такими різними діячами, як Володимир (Зеєв) Жаботинський і Марко Кропивницький. Популярний образ єврейки-вихрестки на початку XX століття позбувся безумовно позитивного ореолу: йшлося вже не про навернення до «нашої» громади, а про зречення «своєї», відмову від власної національності. Збереження євреями національної ідентичності потрактовувалося як приклад і для українців. Колишні конфлікти вже не мали ставати на заваді новому взаєморозумінню.

Леся Українка була серед небагатьох письменників, які принципово не зверталися до цієї проблематики, опе- руючи лише традиційними біблійними паралелями. Тим не менш, і вона у протистоянні культурній гегемонії Росії виявилася ситуативною союзницею Жаботинського.
МІФОЛОГІЧНІ ОБРАЗИ ТА МОТИВИ БАЛАДИ ПЕТРА СКУНЦЯ «ТРЕПАТА» Й ПОЕМИ ВОЛОДИМИРА САМІЙЛЕНКА «СПРИТНИЙ ЧЕНЧИК»
Authors: Тиховська Оксана
Published: April 2023

Мета статті – проаналізувати міфологічні образи та мотиви балади П. Скунця «Трепета» та поеми В. Самійленка «Спритний ченчик», з’ясувати специфіку переосмислення апокрифічних легенд, образів-символів та теми кохання у цих творах. У баладі П. Скунця «Трепета» (1978) і в поемі В. Самійленка «Спритний ченчик» (1924) ми бачимо різну художню інтерпретацію фольклорних мотивів. П. Скунць вибудовує історію кохання свого ліричного героя у філософському аспекті, лише частково апелюючи до народних легенд про осику (трепету). Поет відмежовуєть- ся від негативного ракурсу зображення цього дерева й наділяє його новими характеристиками: трепета стає символом трепетного кохання, на неї також проєктуються риси культурного героя у змодельованій поетом вставній оповіді про порятунок світу від хаосу, холоду і зла. Ліричний герой балади переживає своєрідний катарсис, згадуючи про давнє кохання, усвідомлюючи безповоротність втрати – неможливість повернення до минулого щастя. Дерево трепета асо- ціюється з тремтінням душі від любові в глобальному значенні цього слова: любові до світу, природи, рідного народу, коханої дівчини. Петро Скунць моделює власний авторський міф, оригінальність його сюжету не викликає сумнівів, і це зумовлює високу художню цінність твору. Поет лише частково дотримується жанрово-стильових особливостей, притаманних фольклорній баладі. Балада «Трепета» є майстерним плетивом потоку свідомості ліричного героя (авто- ра) з міфом про Золоту добу, її занепад і відродження людства завдяки силі любові дивовижного дерева трепети.

Натомість герой поеми В. Самійленка «Спритний ченчик» Дон Хуан не здатен кохати, його почуття мають лише інстинктивний вияв, він не переймається спасінням власної душі, метою його життя є задоволення різних тілесних по- треб. В. Самійленко у гумористичному ракурсі переосмислив тему кохання, народні вірування українців про подорож душі у світ мертвих, зустріч зі святим Петром, а також легенди та бувальщини про відьом. Черницю у ролі безхвостої кобили можна інтерпретувати як гумористично завуальований образ відьми. Сюжет поеми «Спритний ченчик» мо- делює альтернативну модель реальності, котра ґрунтується на маскараді та буфонаді. Виокремлення та аналіз міфо- логічного підґрунтя балади «Трепета» та поеми «Спритний ченчик», їх типологічне зіставлення дає змогу виявити специфіку використання письменниками фольклорних джерел й моделювання ними міфологічних образів.

This study implemented a school-based intervention aimed at improving coping flexibility, and to determine the intervention effects on coping and anxiety in children during the COVID-19 pandemic. A total of 692 first and second year of junior high school students (347 boys, 320 girls, and 25 neither) participated. Of the 19 classes first and second year of junior high school, 10 participated in the intervention in July 2021 and nine participated in January 2022. The results showed that the intervention program effectively reduced students’ anxiety. With regard to coping, there was no change in “seeking support,” a decrease in “problem avoidance,” and an increase in “positive interpretation and recreation.” The current intervention, which aimed at improving coping flexibility, was effective in reducing anxiety and promoting coping among junior high school students during the COVID-19 pandemic. In future it may be necessary discussed to reduce the burden on schools to accept outside experts by using information-technology equipment and other means to conduct the intervention remotely.

Published: April 2023

Decentralization and regional autonomy (DRA) policies have been implemented in Indonesia for 25 years. However, regional independence is still very low in 33 regions/cities in North Sumatra (North Sumatra) because the local revenue (PAD) is much smaller than the regional income and expenditure budget (APBD). The aim of this study is to analyze this phenomenon and find a conceptual framework for reformulating DRA policies. The research method uses mixed methods. The results of the analysis show that 88.49% of the regions are still dependent on transfer funds from the central government, so the nature of autonomy, namely the independence of autonomous regions, is still far from expectations. In the long run, it is important to reformulate policies through the Policy Reformulation Action-Cycle Framework (PRACYF). Theoretically, PRACYF has conceptual implications for the development of public policy and DRA, while in practice it can have implications for increasing the independence of autonomous regions and the welfare of the people in the regions.

Published: April 2023

This review examines how physical activity can modulate the gut microbiota, taking into account the training intensity used, the value of the load and the age group studied. The aim of the study is to show the significant interaction between exercise and its effects on the gut microbiota. Many of the studies we analysed showed an interesting correlation between the physical activity undertaken and the change in biodiversity and taxon representation, so we concluded that exercise can significantly modulate the composition of the gut microbiome. This also works the other way around, as doing too much intense and taxing exercise can lead to so-called intestinal dysbiosis, which promotes inflammatory reactions and other unfavourable metabolic consequences. Therefore, in this review, we have analysed the latest and most interesting body of literature oscillating around the complex relationship between the movement undertaken and its impact on the microbiome.
Research on SOC estimation of residual power of lithium-ion batteries for electric vehicles based on extended Kalman filtering algorithm
Authors: Jiang Haifeng
Published: April 2023

As the energy carrier of electric vehicles, how to accurately estimate the remaining power (SOC) of the battery is one of the key technologies in the field of electric vehicle design. Effective estimation of SOC can bring accurate continuous mileage information to the driver, theoretically avoid overcharging and discharging the battery, and also protect the driver's driving safety. In the research of SOC estimation method, constructing a suitable battery model is an important means to improve SOC estimation and to improve the prediction accuracy. In order to obtain a higher response accuracy of the model, this paper proposes an electric vehicle SOC model based on the extended Kalman filter algorithm. Based on the actual data of lithium-ion power battery, SOC estimation research is carried out. The research shows that: when the internal temperature of the battery is the same as the ambient temperature, and both are 25 °C, the model is accurate, the terminal voltage difference is small, and the average voltage difference is 9mV respectively; at room temperature, the extended Kalman filter algorithm has a significant effect on the recovery percentage of SOC voltage. The average is over 73%, and the accuracy is high. The extended Kalman algorithm in this paper we use to estimate the SOC current waveform. The simulation results show that the SOC discharge current is 4A, which has high estimation accuracy and strong applicability.

Linear programming is a widely applicable mathematical operation method. In this paper, two solutions of linear programming and state parameter extraction can be used to simplify the inequality group and transfer the high-dimensional state utility function in football. This can speed up the generation of joint strategies for football teams in the game. This paper uses the free-kick technical football cooperation as an example to conduct an empirical study on the linear programming method of state parameters. In this paper, combined with the traditional motion information modeling method, a free ball path planning based on the linear programming gradient method is established. At the same time, this paper adopts an asymptotic method based on linear programming to solve the trajectory of any football. Finally, an experimental study on the linear programming gradient method for state feature vectorization is carried out. Experiments verify the effectiveness of this method. The mathematical model accurately predicts the linear programming of football training.

A New Multistage Clustering Algorithm for Optimal VAr Planning For Dynamic Voltage Stability Analysis
Authors: V Bharathi , Atla Chandrasekhar Reddy , Shivakumar M. R.
Published: April 2023

Power systems need reactive power support to withstand voltage instability issues. The Volt Ampere reactive (VAr) resources are to be optimally determined for location and size. Generally, candidate locations are determined based on the ranking of buses according to sensitivity indices, and the Trajectory Sensitivity Index (TSI) is the most widely used sensitivity index. However, the locations identified by ranking the buses at the system level using the TSI method do not guarantee an optimal VAr solution. The recent methods based on dividing the power system into zones address the issue of optimality. The prevailing zoning methods are based on the computation of the electrical distance between buses and do not address the zoning scenario where the electrical distance between the buses is indeterminable. This paper introduces a new multistage algorithm for grouping the buses into zones even when the electrical distance is indeterminable. The new proposed strategy encompasses applying proposed analytical and parametric techniques after the standard clustering steps. A new index, namely the Bilateral Sensitivity Index (BSI), is introduced to quantify the proximity of buses. The TSI-based zonal level ranking of buses is introduced. The proposed strategy demonstrates that when TSI is employed to rank the buses at the zonal level rather than at the system level, it helps towards an optimal VAr solution. The new multistage clustering strategy is integrated into the generalized Dynamic Voltage Stability Analysis (DVSA) framework for optimal VAr determination and applied to study the voltage collapse phenomenon on a practical 24-bus system in the southern part of India. The results demonstrate the proposed approach’s efficacy in mitigating voltage instability issues through optimal VAr support.
Recycling Potential of Onyx Composite for Additive Manufacturing
Authors: Mergulhão Marina , Magalhães Sofia , Costa José M.
Published: April 2023

The evaluation of product cycles has allowed companies to transition from linear to circular production and reuse collected material. However, recycling is only sometimes straightforward and involves the material history of thermal cycles, the recycled content, and other characteristics. Therefore, recycling processes’ adversities and products need to be studied. Thus, this study aims to obtain a recycled Onyx filament, a micro carbon fiber-filled nylon, and evaluate its recycling potential to produce 3D printed samples. Tensile tests, optical microscopy, and evaluation of the quality of 3D printed samples and filaments were conducted. Under the studied conditions, the recycled Onyx filament did not present a satisfactory performance for 3D Printing, leading to nozzle clogs and precluding the 3D printed samples from being completed. These problems have been related to previous work. Therefore, it is necessary to investigate Onyx recycling under other conditions, such as recycling conditions or adding virgin material during recycling.
A systematic review of Intelligent Fault-Tolerant Protection Scheme for Multi-terminal HVDC Grids
Authors: Rodino Analcísio António , Araújo Rui Esteves
Published: April 2023

Due to the advancement of power electronics devices and control techniques, the modular multilevel converter (MMC) has become the most attractive converter for multiterminal direct current (MTDC) grids thanks to its most relevant features, such as modularity and scalability. Despite their advantages, conventional MMCs face a major challenge with: i) fault-tolerant operation strategy; i) energy losses in conversion; iii) lack of DC fault handling capability. This paper provides a systematic review to identify the gaps in the literature about Intelligent Fault-Tolerant Protection Schemes for multi-terminal HVDC grids. Through the bibliometric analysis, it was possible to identify topics still to be developed within the four main clusters (Offshore wind farms, Wind turbines, Voltage Source Converters, and Wind power). The research topic opens three research paths: the first is the analysis of failures in HVDC (High Voltage Direct Current) grid equipment by the FDD (Fault Detection and Diagnosis) method; the second is failure analysis by the IFDD (Inverse Fault Detection and Diagnosis) method and the third is the possibility of interconnecting the different energy generation zones with different frequencies.

Research subject. Garnets from silicate-carbonate formations and their halos with skarn mineral associations, developedin the historical mines and pits of the Southern Urals: Zelentsovskaya, Nikolaje-Maximilianovskaya, Akhmatovskaya,Perovskitovaya, Gubensky massif, Praskovie-Evgenyevskaya and Shishimskaya.

   Aim. To study the nature of silicate-carbonate formations of debatable origin.

   Materials and methods. The composition of garnets distributed both in silicate-carbonate formations and in rocks with skarn mineral associations was analyzed using SEM-EDS (IPGG RAS) and SIMS (Yaroslavl branch of IPT RAS).

   Results. The garnets from silicate-carbonate rocks show predominantly a dark to black color, a combination of simple rhombododecahedron and tetragontrioctahedron shapes. In terms of composition, these materials correspond to andradite – Ti-andradite, with the share of shorlmite and morimotoite end-members reaching 30 %. The garnets from calcareous skarns are reddish in color and have a rhombododecahedric habitus. In terms of composition, these garnets correspond to an andradite-grossular isomorphic series, with the share of shorlomite and morimotite end-members not exceeding 3 %. For these garnets, the content of trace and rare-earth elements was determined for the first time, and a posi tive correlation of Ti with U, Y, Zr, Hf and Nb was established. Figurative points on binary diagrams (in coordinate axes of rare-earth content) are plotted as a trend of garnet composition in the grossular–andradite–Ti-andradite series. Garnets from silicate-carbonate rocks, unlike those from skarn mineral associations, are characterized by an increased rare-earth elements content. The main feature of the rare-earth elements distribution spectra in garnets is a positive Eu-anomaly, which is observed in all studied garnets.

   Conclusion. The data obtained allowed the authors to assume that garnets from silicate-carbonate formations and their halos were formed as a result of a single geological process, essentially close to skarn formation. The results of the petrographic-mineralogical and geochemical studies assume that the “carbonatite” nature of the silicate-carbo nate rocks of the Southern Urals is unlikely.
Aesthetic Dividuations in a Globalized Art World
Authors: Ott Michaela
Published: April 2023

As a professor of philosophy in the art academy of Hamburg, I deal with contemporary art practices; as a theorist of aesthetics I try to determine what kind of aesthetic and artistic developments seem to be significant for our times, and which kind of philosophical theories I can offer in order to better conceptualize and understand the given art productions. At the same time, I attempt to transcend contemporary tendencies and concepts and to foster students’ art practices in a way that makes them meaningful for the future.
This lecture seeks to provide a possible interpretation of actual art practices in a globalized world, reflecting also on big art exhibitions such as Documenta 14 and on African films. It sketches a specific aesthetic program called Afropolitanism as an understanding which could be conceived of as paradigmatic for our globalized times. Afropolitanism is a term coined by the South African theorist Achille Mbembe in one of his 2010 book Sortir de la grande nuit. Essai sur l’Afrique décolonisé. Starting from there I want to offer a philosophical concept that goes far beyond the European context and hopes to provide a possible conceptual frame for a more complex understanding of the culturally and artistically entangled and hybridized expressions of our days, including those of human subjectivation. I call this concept dividuation as I have explained further in my book Dividuations: Theories of Participation, which was published in English in 2018.

Mário Pedrosa’s Turn Point: From the Good Neighbour Policy in the United States to the Brazilian Modern Project (1938–1951)
Authors: Mari Marcelo
Published: April 2023

Mário Pedrosa contributed in a decisive way to the formation and development of Brazilian politics and art in the 20th century. Pedrosa traveled to the United States and started to live in New York at the end of 1938. In the field of the arts, he took a position on the debate between Independent Revolutionary Art and Instrumentalized Art. In the essay “Portinari – from Brodósqui to the murals in Washington” (1942), Pedrosa overcomes the defense of art as a revolutionary weapon, which was his position at the conference on the German artist Käthe Kollwitz, presented at the Club of Modern Artists, in Brazil in 1933. From 1942, he approached the position of independence of art, in relation to the government's instrumentation policies.

Cinema, Architecture and Conditions of Artistic Experience in Big Cities
Authors: Campaner Miguel Ferrari Sônia
Published: April 2023

In the first part of the paper, we take Walter Benjamin’s essay on cinema as a reference when thinking about his prognostic values. We are interested in these prognoses that affirm the transformation of art and its function, and which call our attention to the loss of transcendence and the decline of the aura of the work of art. At the same time, they show possibilities that affirm the continuity of art with a different role. The form of art that is suitable for this reflection is the cinema, and the parallel drawn by the philosopher between cinema and architecture. Our intention is to reflect on this parallel and the urban interventions as artistic forms of aesthetic modernity. Then I propose the discussion of the notion of art out of axis. The axis, we think of something that organizes and defines. The proposal to think about art in Latin America is made thinking about the center-periphery axis. However, we can still consider another starting point, thus changing direction, a change that is not only geographic but of what will be the reference to think of art, taking into account the artistic production submitted to the market and the stock exchange. Nowadays, we seek to account for the phenomenon of urbanistic growth, and we remain perplexed by the force that assumed financial capitalism, which, now, not only transforms everything into the value of exchange but has also resulted in the loss of any meaningful reference to the original value.

Contemporary Aesthetics of the Akurino: A Religion or a Cultural Movement?
Authors: Muthuma Gitau
Published: April 2023

This paper examines the aesthetics of the worship rituals, music, artifacts and the oral tradition of the Holy Ghost Church of East Africa, or Akurino religious sect, which is a unique blend of Christian religious practices and traditional African worship systems. The main question here is whether the Akurino are a Christian religious sect or a cultural movement? The Akurino are significantly interesting due to the fact that they claim to be an indigenous African Christian religion, among many such others. But the fact that they are mostly found in Central Kenya and the Rift Valley regions, and are confined among the Gikuyu people only and have not attracted adherents from other segments of society, raises the question as to whether they may not also be a cult or a cultural movement. The Akurino started appearing in the middle of the 1920s. They grew strictly out of indigenous leadership. Their first generation membership came out of various missions as well as the unchurched population that followed Gikuyu traditional religion. The group was in its infancy and was functioning in various parts of Gikuyu country, but had little influence with the general population, its appeal being to such individuals as had been pronounced 'sinners' by missionaries, and to others who had been cured of diseases.

Neuroarthistory: Several Notes on Historical Sources
Authors: Milosavljević Angelina
Published: April 2023

In his proposal for a new methodological approach to the history of art, neuroarthistory, art historian John Onians based his argument in philosophy and art theory ranging from Aristotle to Leonardo, and from Reynolds to Zeki, and neuroaesthetics. However, he omitted from his overview the late Renaissance and Baroque traditions in which one can easily find writings on human cognitive ability (on intellect, senses, and imagination) and its bearings on art. In this preliminary note, we point to several 16th-century humanists, such as Gianfrancesco Pico della Mirandola, Baldassare Castiglione, Benedetto Varchi, and artist and theorist Federico Zuccari, in whose treatments of human cognitive ability we find the application of Aristotelian tradition. Their writings further illuminate the rich and exciting insights into the nature, workings, and results of human cognition.

Terapia cognitivo-comportamental adaptada à religiosidade do paciente: um guia prático para o espiritismo
Authors: Costa Marianna de Abreu , Moreira-Almeida Alexander
Published: April 2023

Sabe-se que a religiosidade e a espiritualidade (R/E) impactam a saúde física e mental e há um crescente reconhecimento por entidades clínicas e científicas da necessidade de se abordar R/E na prática, em especial no contexto psicoterápico. Revisões sistemáticas mostraram a eficácia da terapia cognitivo-comportamental (TCC) adaptada à diversas religiões. No entanto, não há diretrizes que abordem o espiritismo, terceira maior religião do Brasil e que tem uma influência sobre a sociedade brasileira já que suas crenças e práticas são frequentemente adotadas por pessoas de outras filiações religiosas. Dessa forma, o presente estudo pretende cobrir duas importantes lacunas na literatura: a dissociação que existe entre o corpo de evidências e a prática clínica e a falta de estudos que abordem o espiritismo. Dessa forma, descrições práticas das técnicas de TCC adaptadas ao contexto espírita são apresentadas, ressaltando-se a necessidade da intervenção ética e centrada no paciente.
Efecto de las atmósferas modificadas activas con gases no convencionales sobre la inhibición de E. coli inoculados en hojas de rúcula (Eruca vesicaria)

Evalúa el efecto de gases no convencionales como el argón (Ar), helio (He), óxido nitroso (N 2 O), altas concentraciones de O 2 y aire, sobre el crecimiento microbiológico en hojas de rúcula (Eruca vesicaria) MPF -1 inoculadas con Escherichia coli. Después de desinfectar con hipoclorito de sodio (95 mg·L , pH 6,5) y enjuagar con agua estéril, las hojas se inocularon con E. coli (6,5 log UFC·g -1 ) y se envasaron en diferentes ambientes enriquecidos con Ar (53% Ar + 41% O 2 + 6% N 2 ); He (53% He + 42% O 2 + 5% N 2 ); N 2 O (53% N 2 O + 42% O 2 + 5% N 2 ), O 2 (80% O 2 + 20% N 2 ) más un testigo envasado en aire (21% O 2 + 80% N 2 ), y se almacenaron a 5 °C durante 10 días. Las concentraciones de gases al interior de las bolsas, E. coli y enterobacterias se determinaron periódicamente. La composición del gas al interior de las bolsas cambió durante el almacenamiento debido principalmente a la respiración de las hojas de rúcula. La concentración de O 2 disminuyó desde 40% a 20-26% en las atmósferas enriquecidas con Ar, He y N 2 O, y de 80 a 58% en el tratamiento con O 2 . Las concentraciones de CO 2 aumentaron en todas las bolsas aproximadamente a 20-23%, salvo en He que alcanzó el 10%. Las -1 atmósferas con Ar y He fueron las más efectivas para disminuir el recuento de E. coli (<5,0 log UFC·g ) y -1 enterobacterias (<7,0 log UFC·g ) después de 10 días. Los gases no convencionales Ar y He redujeron el crecimiento microbiano en hojas de rúcula.
