Introduction. Puumala virus (family Hantaviridae, genus Orthohantavirus) is distributed in most regions of the European part of Russia. However, information about its genetic variants circulating on the territory of the Central Federal District is extremely scarce.
Materials and methods. Rodents tissue samples were tested after reverse transcription by PCR for the presence of hantaviral RNA. The amplified fragments of the L segment were sequenced by the Sanger method. For two samples, sequences of all three segments were obtained using the NGS method. Phylogenetic trees were built in the MEGA-X software.
Results. Puumala virus was found in six samples. Based on the phylogenetic analysis of sequences of three segments, the obtained genetic variants belong to the sublineage previously designated as W-RUS.
Conclusion. A genetic variant of the Puumala virus, belonging to the subline W-RUS, circulates on the territory of the Volokolamsk district of Moscow region.

Introdução: A pandemia causada pela disseminação do vírus SARS-CoV-2 trouxe demandas até então nunca previstas para os sistemas de saúde e a sociedade. Dentre os maiores desafios, salienta-se a importância da manutenção do tratamento de doenças potencialmente letais que seguiram em paralelo à epidemia mundial que se instalou. O tratamento do câncer de mama, uma doença tempo dependente, também foi comprometido, pois havia a necessidade da priorização de recursos financeiros, insumos, medicamentos, e especialmente, leitos hospitalares para assistência aos infectados pelo coronavírus. Cirurgias foram suspensas e centros cirúrgicos desativados. Objetivos: Comparar o número de procedimentos cirúrgicos mamários entre os períodos pré e durante a pandemia; identificar o impacto sobre o quantitativo proporcional de cirurgias realizadas. Métodos: Trata-se de um estudo de coorte retrospectivo com a revisão dos procedimentos realizados de janeiro de 2015 a junho de 2021. Resultados: Foram incluídos 899 pacientes, a maioria do sexo feminino, sendo 58,5% casos oncológicos. O procedimento cirúrgico mais realizado, tanto no período pré-pandemia como pandêmico, foi a cirurgia oncológica conservadora (setorectomia ou quadrantectomia). Houve diferença significativa entre o número de procedimentos realizados antes e durante a pandemia, com uma queda de 43% no número de cirurigas realizadas durante a pandemia. Não houve diferença significativa no padrão de cirurgias realizadas no período. Conclusão: A pandemia provocou importante redução na realização de cirurgias eletivas no período analisado, gerando atrasos nas intervenções, o que a literatura aponta como risco potencial para progressão da doença e elevação das taxas de óbitos
Climate Change and Transatlantic Slavery
Authors: Niles Keron
Published: September 2023

The article examines the causes and effects of climate change and juxtaposes these with the transatlantic slave trade to glean what lessons, if any, can be learnt. It further explores any systemic linkages between transatlantic slavery and climate change, and proffers sustainable recommendations for mitigating the current dilemmas associated with slavery and climate change. To this end, this study finds that the effects of transatlantic slavery and climate change reveal multi-generational impacts related to a lack of representation, the disproportionate distribution of benefits and costs, cultural losses, and a lack of frameworks to facilitate compensation to those adversely affected. The article concludes by underscoring useful measures that can be adopted to combat the proliferation of similar problems in the future.

Context-based teaching experiences of chemistry teachers: Expectations, gains and applicability conditions
Authors: Mustafaoğlu Fatma Merve , Yücel Ayşe Seda
Published: September 2023

This research aimed to investigate the expectations and gains of teachers who designed and used context-based teaching materials in their classes and to reveal their views on the applicability of this teaching approach. The methodology of this research was the case study. The research was carried out with two chemistry teachers who participated in the In-Service Training Course on Context-Based Chemistry Teaching performed by the researcher. Data collection tools used in the research were semi-structured interviews, field notes and evaluation reports. As a result, it was concluded that teachers believed that context-based instruction increased students' motivation, achievement and participation in the lesson. Also, both teachers stated that their competencies in contextbased teaching had improved after practising it. However, it was revealed that teachers thought that in order to use context-based teaching, learning environments should be arranged in accordance with the approach and universities and Turkish Ministry of National Education should work in cooperation.
Polimorfismos g-2548a en el gen de leptina y q223r en el gen del receptor de leptina: una revisión de su relación con el sobrepeso y la obesidad
Authors: Calderon Vega Edna Ruth , Melgar Sergio , Parra Rojas Isela
Published: September 2023

La obesidad es una enfermedad compleja y multifactorial resultante de efectos combinados entre genes, ambiente y estilo de vida que influyen en la respuesta individual a la dieta y la actividad física, generando aumento de la adiposidad y por lo tanto del índice de masa corporal (IMC). Se considera una pandemia por encontrarse diseminada a nivel mundial, con aumento constante de su prevalencia y de complicaciones metabólicas asociadas a enfermedades crónicas no transmisibles (ECNT). La leptina (LEP) y el receptor de leptina (LEPR) son genes que han sido evaluados en la búsqueda de variantes que podrían estar relacionadas con la obesidad y sus complicaciones cardiometabólicas. La presente es una descripción narrativa de literatura cuyo objetivo es revisar el conocimiento actual sobre la relación de los polimorfismos de un solo nucleótido (SNPs) LEP G2548A (rs7799039) y LEPR Q223R (rs1137101) con la obesidad y el sobrepeso, según elIMC. Se realizaron búsquedas en las bases de datos de publicaciones desde el2015 a la fecha, en español e inglés, en NCBI PubMed, Google Scholar y SCOPUS. Se revisaron 90 artículos, de las cuales se eligieron las publicaciones para la presente revisión. Se encontraron revisiones de suma importancia donde se reporta la asociación de los polimorfismos de LEP y LEPR con la presencia de sobrepeso y obesidad. Sin embargo, no se cuenta con este tipo de información en población guatemalteca, lo que pone en perspectiva su relevancia para su investigación.

In the article, the authors discussed the course in the subject of heritage protection, including the conservation of historic buildings and placing new objects within historically formed development, at the Faculty of Architecture of the Poznan University of Technology. The authors emphasise the importance of analysing the composition of historical buildings' elevations existing in the vicinity of the designed object. Capturing the main compositional structures and guidelines of the facades of historical objects is difficult, and hence the authors show different ways to achieve this, emphasising different ways of observing the object and graphically recording the layout of the composition and later using these effects in the design stage. The aim is to acquire and improve the ability to fit the designed object into its historic context.

The paper summarises conservation research carried out on abandoned wooden Ukrainian Greek-Catholic churches from south-eastern Poland. As an example, two architectural objects remaining in complete ruin are discussed: the church in Babice and the church in Miękisz Stary. Both of them were erected in log construction and have rich interior polychrome. Conservation methodology was discussed, which must combine often contradictory challenges and aspects: both the need to stabilise the architectural body (which requires the replacement of a significant amount of historical substance) and the intention to preserve as much as possible the remains of the interior painting decoration (in the majority, polychrome was made directly on structural elements). The method of polychrome transfer was therefore discussed, which guarantees the preservation of the authentic character of the temples as well as their aesthetic and historical value. In addition, a detailed study of the remains of the iconostases of both temples (icons are currently stored in museum warehouses) and the issue of the possible restitution of the iconostases, along with a discussion of the necessary technical solutions for this procedure, are presented.

Materials belonging to the polychromy and gilding of the sculpture ‘Our Lady of Sorrows, which belongs to the collection of a church in Garopaba, Santa Catarina, southern Brazil, were analyzed by multiple techniques. The analysis by μ-Raman and FTIR indicated the use of the ultramarine blue pigment, confirmed by EDS, with calcium carbonate observed in the base of preparation. The results show the use of gold leaf based on a gold and silver alloy, and the use of Armenian bole with clay and traces of manganese, as the base for fixing the gold leaf was characterized. GC-MS analysis suggested the use of plant oil in the painting process. Finally, the EPR analysis showed the presence of Fe3+, Mn2+ and organic radicals from the degradation of the binder, suggesting the formation of complexes with the degradation products, this being one of the first reports in this type of painting.
Un medio, el cuerpo. Un miedo, el cuerpo
Authors: Awad Carolina Muñoz
Published: September 2023

I needed to feel held. Physically, by the inanimate, during a pandemic that was transmitted by touch. Doing nothing, while performing, became the subject of my studies. How do I perform with a body that does not know how it uses space, how much it measures, and how much it feels? Counting, keeping scores, and pushing to the limit of uncomfortability, became my way of establishing the timelines. Seventeen lemons, my own body weight, and 42 cm, are some of the objective parameters I found while enacting absurdity, improvisation, and movement through my human body. The resourcing of the works is part of the pieces themselves, leaving a trace of actions involved, blurring the boundary between daily life and the art I was creating. Yvonne Rainer, Herman Hertzberger, Gilles Deleuze, Rosalind Krauss, and Ernesto Pujol, among others, enter the conversation within my experimentations, as critical references, and guiding thoughts for the questions I have. The performative actions I produced are part of an embodied investigation that, through myself, encounters displacement, estrangement, irreversible loss, and grief, within a 2-year time frame.
Refugees and refugee applicants’ voices in Brazilian cities
Authors: de Oliveira Laís Gonzales
Published: September 2023

This paper provides an analysis of the struggles faced by refugees and refugee applicants as they seek recognition and the effectiveness of their rights within Brazilian cities, particularly focusing on full political participation at the municipal level. Employing juridical-sociological research methods, including theoretical bibliographical research and critical analysis, it is concluded that the formal recognition of the right to the city holds significant relevance, serving both as a catalyst for the concrete realization of these rights and as a means to affirm the identity of individuals involved. Although the law may result in the maintenance of injustices, the institutionalized means of participation should not be abandoned but reconstructed.
Wisdom capacities in people with and without chronic mental health problems: A representative survey on a general German adult population
Authors: Muschalla Beate
Published: September 2023

Wisdom capacities are important for coping with difficult and ambiguous life situations. People with chronic mental health problems often have problems in coping with life problems. Until now, there are no comparative and representative data on the distribution of wisdom capacities people with and without chronic mental health problems. Identifying strengths and limitations in wisdom capacities in both groups will give a basis for specific focus in wisdom training in clinical settings and public health. This cross-sectional observation study examined a German population with a representative sample of 2505 persons aged 16 – 95 years in 2019. Sociodemographic data as well as chronic mental illnesses data were collected, and wisdom capacities were assessed by the 12-WD Wisdom Scale. The surveys were carried out using interviews and self-report questionnaires at the respondents’ homes by an experienced social research company. The wisdom capacities value and problem relativization, as well as emotion acceptance were scored the highest by people with and without chronic mental health problems. Uncertainty tolerance, sustainability and perspective change received the lowest scores. People with chronic mental health problems had slightly lower overall wisdom affinity (M = 7.00, SD = 1.41 on a scale of 0 – 10) as compared to mentally healthy people (M = 7.7, SD = 1.38). Specifically, persons with chronic mental health problems reported the lowest ratings on wisdom capacities requiring active cognitive reflections (sustainability, perspective change, and uncertainty tolerance). In conclusion, since there are rather small quantitative differences between persons with and without chronic mental health problems, the wisdom concept seems appropriate to be applied to all individuals, regardless of the severity and nature of mental health problems. Wisdom enhancement, for instance, by means of wisdom training, may be focused on wisdom capacities which were rated comparably low, including perspective change, uncertainty tolerance and sustainability.

Published: September 2023

Abnormalities in thyroid function may induce affective, anxious, psychotic, and cognitive disorders and are a potential marker for assessing suicidal risk in patients suffering from psychiatric disorders. This retrospective, cross-sectional, electronic, and data-based study, comprising 118 adult psychiatric patients, aimed to establish differences in the concentrations of total T3, T4, and thyroid-stimulating hormone among patients diagnosed with common psychiatric disorders. The analysis encompassed the levels of these hormones in patients who had attempted suicide and those who had not. Lower values of total T3 were observed in patients with depressive disorder compared to patients with psychotic and bipolar disorder, as well as the control group. Furthermore, lower total T3 values were observed in patients who had reported a suicide attempt in their lives compared to participants who had not attempted suicide. These findings suggest a potential link between thyroid hormones and the regulation of central serotonin activity. The study underscores the importance of routinely assessing thyroid function in clinical practice to facilitate early detection of suicidality and the prevention of suicide.

Rice – wheat cropping system is backbone of agriculture and responsible for achieving food security in the country. However, because of threat to sustainability of this system there is urgent need of crop diversification. A field experiment to diversify the rice – wheat system in wet zone of Himachal Pradesh was carried out during the year 2017-18 at Bhadiarkhar research farm, Department of Agronomy, CSK HPKV, Palampur to evaluate productivity, profitability and energy pattern of eight different rice-based cropping systems. Results revealed that rice – palak – cucumber system resulted in significantly higher rice grain equivalent yield (16477 kg/ha), profitability (₹ 848.76/ha/day), productivity (63.62 kg/ha/day), net returns (₹ 219828/ha) and benefit cost ratio than other crop sequences whereas lowest rice grain equivalent yield (6259 kg/ha) and productivity (21.44 kg/ha/day) was recorded from traditional rice – wheat system. However, land utilization ratio and duration were found to be maximum from turmeric – pea – summer squash system (86.85) followed by rice – wheat. Energy utilization was noticed highest from rice – lettuce – potato + coriander system followed by turmeric – pea – summer squash. Maximum energy output (280.42×103MJ/ha) and energy efficiency (10.58) were observed in rice – palak – cucumber system.

Conventional farming always modifying by good innovation in agriculture,  while the holistic idea of organic farming checks the use of synthetic inputs where in opposite side, the concept of natural farming allowing farming with few traditional and locally available inputs. The all three farming concepts are fundamentally different, to check it on real field, a experiment was conducted on medium black calcareous clayey soil at Junagadh (Gujarat) during rabi 2019-20 to kharif 2020 in order to evaluate low cost natural farming, organic farming and conventional farming in major six crops of Gujarat. The experimental results revealed that conventional farming module significantly increased yields of crops as compared to organic farming and low cost natural farming. Significantly higher available nitrogen, phosphorous and potassium after harvest was found under conventional farming, while organic farming module registered significantly higher organic carbon, heat soluble S; DTPA-extractable Fe, Zn, Cu and Mn after harvest, which was found at par with conventional farming. Economic analysis showed that maximum net returns gross returns, and B:C ratio were observed under conventional farming module.

A study was carried out for three years (2019, 2020 & 2021) in the experimental field at ICAR Research Complex for NEH Region, Mizoram Centre, Kolasib, Mizoram to check the performances of seven ginger genotypes viz., Gurubathani, Bold Nadia, Bhaise, John's ginger, PGS 121, PGS 95 and PGS 102 against Local ginger cv Thingria and their economic feasibility for commercialization in Mizoram, India. Out of seven genotypes when compared with Local ginger cv Thingria, five genotypes have out yielded Local cultivar in the range of 21.25 to 45.45% with Bhaise having 45.45% higher rhizome yield than Local ginger. On the other hand, Bold Nadia possesses a combination of good quality traits. The highest B:C ratio was obtained in Bhaise (2.08) followed by PGS 102 (1.99), Gorubathani (1.95) and Bold Nadia (1.87). The highest cost of cultivation was contributed by labour cost which was 53.40% of total cost of cultivation. The four genotypes viz., Bold Nadia, Bhaise, PGS 102 and Gorubathani can be selected as potential genotypes possessing optimum combination of all traits. Based on economic analysis, these genotypes can be considered for commercial purposes under Mizoram condition. Different production systems such as intercropping, pro-tray technology, and bulb extraction method may increase the overall income of farmers. Farmers need to venture the possibilities of value addition in ginger on commercial basis. Government intervention is required for creating marketing infrastructures, initiating youth-centered schemes, occasional skill training and developing farmer-friendly policies to protect them from market risks and exploitation. Ginger has been an important horticultural crop and widely marketed spice crop of Mizoram, a potential enterprise contributing to state economy

Published: September 2023

Kerala State is highly vulnerable to natural disasters, mainly soil erosion due to changing climatic dynamics in the steep slope. In 2018 and 2019 flood, some districts in Kerala State were affected by significant floods due to extreme and prolonged rainfall, leads to large and small landslides. Malappuram is one of the districts that got affected in 2018 and 2019 flood. Disaster risks are augmented by a critical factor that has been silently rising in the State now, which is change in the land use pattern and practices. Hence, the Land Use and Land Cover Dynamics study was conducted in the selected watersheds (Kakkarathode – Pulikkal and Palathingal) of Malappuram district, and spotted major landslides in the area. The LULC dynamics were carried out in the different time periods like 2013, 2018 and 2020. LISS IV (5.8 m resolution) satellite images were used for the analysis and field visit, to identify the related changes. Accuracy of the classification was evaluated using error matrices and kappa statistics. The overall accuracies for 2013, 2018 and 2020 were 84.93%, 86.21% and 87.5% respectively and the corresponding Kappa values were 0.82, 0.84 and 0.85 which indicates the high accuracy of the classification. The flood has mainly affected Plantation, Paddy and Mixed Plantation which had been decreased during 2018-20 and has resulted in the emergence of more Barren land and Waste Land. LULC helps in identifying the changes in the erosion prone areas. Moreover, erosion hazardous area and its prioritization in applying the soil management and conservation practices can be effectively done using LULC change assessment. Nature based solutions such as planting trees and grasses (like shrubs, vetiver grass etc.), construction of ponds, creation of green walls and assemblage of vegetations can be adopted in the region of high-risk hazardous area depending on the categorized zone.
Combining predictive distributions of electricity prices. Does minimizing the CRPS lead to optimal decisions in day-ahead bidding?
Authors: Nitka Weronika , Weron Rafał
Published: September 2023

Probabilistic price forecasting has recently gained attention in power trading because decisions based on such predictions can yield significantly higher profits than those made with point forecasts alone. At the same time, methods are being developed to combine predictive distributions, since no model is perfect and averaging generally improves forecasting performance. In this article, we address the question of whether using CRPS learning, a novel weighting technique minimizing the continuous ranked probability score (CRPS), leads to optimal decisions in day-ahead bidding. To this end, we conduct an empirical study using hourly day-ahead electricity prices from the German EPEX market. We find that increasing the diversity of an ensemble can have a positive impact on accuracy. At the same time, the higher computational cost of using CRPS learning compared to an equal-weighted aggregation of distributions is not offset by higher profits, despite significantly more accurate predictions.
Quantum Continuants, Quantum Rotundus and Triangulations of Annuli
Authors: Leclere Ludivine , Morier-Genoud Sophie
Published: September 2023

We give enumerative interpretations of the polynomials arising as numerators and denominators of the $q$-deformed rational numbers introduced by Morier-Genoud and Ovsienko. The considered polynomials are quantum analogues of the classical continuants and of their cyclically invariant versions called rotundi. The combinatorial models involve triangulations of polygons and annuli. We prove that the quantum continuants are the coarea-generating functions of paths in a triangulated polygon and that the quantum rotundi are the (co)area-generating functions of closed loops on a triangulated annulus.
Malignant tumors of the external auditory canal: diagnosis, treatment, genetic landscape, biomarkers, and clinical outcome
Authors: Athanasopoulos Michael , Goulioumis Anastasios , Athanasopoulos Ioannis
Published: September 2023

Malignant tumors of the external auditory canal (EAC) are rare neoplasms that appear in the head and neck area. A common feature of these malignancies is their rarity, as well as their delayed diagnosis due to the appearance of non-specific symptoms that mimic various benign otologic conditions. The reported histological types of cancer of the external ear are: squamous cell carcinoma, basal cell carcinoma, malignant melanoma, Merkel cell carcinoma, angiosarcoma, adnexal carcinoma (including ceruminous adenocarcinoma and adenoid cystic carcinoma), and lymphoma (Lancet Oncol. 2005;6:411–20. doi: 10.1016/S1470-2045(05)70208-4). Several therapeutic interventions have been proposed, primarily orientated towards the cure of the patient, placing the surgical excision of the lesions at the tip of the spear. Subsequently and depending on the clinical stage and the pathological characteristics of the tumor, radiation, chemotherapy, a combination thereof, or some form of palliative treatment for particularly advanced cases, may be recommended. The aim of all the above-mentioned approaches is the complete resection of the mass with negative surgical margins along with lymph node dissection, the elimination of any residual disease or metastasis, and the improvement of survival. The anatomical complexity of the region will always remain a demanding challenge. Nevertheless, advances in the fields of ear microsurgery, imaging, radiation, molecular biology, and genomics have led to remarkable outcomes compared to the past, with a view to the patient’s quality of life. Large, well-organized, and prospective studies with the participation of multiple centers in contrast to existing retrospective studies with a limited number of patients will help to establish universally accepted guidelines. The exploration of the molecular and genetic background of these cancers in conjunction with the search for new biomarkers and target molecules seems promising for providing upgraded and more personalized treatment modalities for the future.

Authors:   Korean Association for Literacy, Kim Inok
Published: September 2023

This study aims to consider the cultural meaning in modern digital society reflected in webtoons through the negotiation and interrelationship between diverse cultural contents centering on the characteristics of webtoon. The understanding of their cultural contents reveals their sociocultural effects through communication by being mediated in their contemporary social context. Thus, the exploration of cultural negotiation and interrelationship in webtoons, which attracts attention in the Korean content market, contributes to subjective cultural literacy.
Webtoon services via the web and platforms have caused webtoons to be recognized as cultural content with the cross-genre openness and high expansibility in a digital environment. In the contextual aspect, the story-type webtoon, which actively borrows daily contents representing the contemporary Korean public, has contributed to securing a fixed fandom. Contrariwise, on the technical side, the introduction of new technology optimized for the expanded mobile environment spurred a media-based change dubbed multi-platform storytelling, thereby facilitating the evolution of webtoons into important IP(intellectual property).
Webtoons’ multi-connectivity and problem-based storytelling, which induce aggressive intervention and participation in its fans, are significant in affording opportunities for the effective application of the convergence-based and creative thinking, which enhances cultural literacy with respect to openness and expansibility in cultural contents.

Published: September 2023

This study addresses the issue of creating persuasive individuals who possess critical thinking skills, analytical reasoning, and effective communication abilities.
The focus is on cultivating talents with the ability to communicate persuasively through the development of an educational model for university writing. In order to achieve this, an examination of the general trends and changes in writing education courses at domestic universities over the past 20 years since the 2000s was conducted. By comparing these findings with the writing education curriculum at S University, the unique characteristics of S University’s writing education were explored.
The writing education at S University has evolved into an educational model that effectively involves learners’ voluntary participation in class and maximizes their writing experiences. To verify this, the study proposed an educational module with a three-step structure, consisting of “Foundations of Writing - Process of Writing - Types of Writing.” It analyzed how S University’s writing education model positively reflects enhancement of learners’ motivation and efficacy in writing classes. Detailed lecture topics, learning contents, related learning activities, and assignments for each module are presented as examples. Additionally, to provide a detailed description of how the classes are conducted, the study examined evaluation cases utilizing achievement-based assessment criteria, presented the outcomes of a writing competition as a learning activity, and explored the effectiveness of the classes through self-efficacy diagnosis of writing skills. This study reaffirms the necessity of university writing education for cultivating communication skills and fostering creative reasoning in the foundational liberal arts curriculum of universities. Furthermore, it is expected to have significance as it proposes an educational module suitable for freshmen-level writing education.

Published: September 2023

This study examined learners’ satisfaction and expectations of a writing course, titled “Basic Writing,” at D University, using a questionnaire survey administered to 126 students taking this course. The findings revealed a high level of student satisfaction with the class. Additionally, the overall class evaluation by students, the extent of assistance provided to improve students’ thinking ability and expression skills, and the need for writing classes were all positively perceived. Students felt that the professor’s expertise contributed to their positive perceptions and satisfaction levels. Students who had somewhat adapted to online classes due to the coronavirus disease preferred it to the current face-to-face mode, which the university has reverted to after the pandemic. Their expectations regarding the class timings and study mode are more related to operational rather than educational aspect. While the results of this study cannot be generalized due to the relatively small sample size, they still provide valuable insights into students’ satisfaction levels and their needs regarding writing classes.

Published: September 2023

This study lays the groundwork for designing digital literacy classes for university students in South Korea by reviewing theoretical discussions and previous classroom practices. Based on an analysis of previous research and related materials, the study examines the syllabi of introductory courses at 10 institutions to explore their digital literacy curricula, determine the contents and values taught at each institution, and the intersection of these curricula with previous theoretical discussions on digital literacy. Evidently, there are inherent limitations due to the size of the dataset. However, it is possible to assess the approach of each institution regarding digital literacy education and explore the current status of education. The results are significant because the study identifies commonalities and differences among them. Moreover, the results can serve as a basis for designing digital literacy classes that fit the Korean context and provide directions for future research to identify other notable aspects.

Published: September 2023

This study uses text mining to analyze the lexical corpus found in the introductory phrase of South Korean “Sebasi Talk” speeches, categorizing the speeches into different topics. Sebasi Talk speeches can be classed into three themes with the following implications. First, through the theme “Family and Social Connections,” Korean learners can develop an understanding of the importance of family, social relationships, and the pursuit of happiness as the theme conveys the significance of the family as a social unit in Korean culture. Second, the theme of “Personality and Happiness of Success,” enables learners to understand the social perspective of being recognized for their values and pursuing success and happiness simultaneously, as the theme indicates that personality growth, goal achievement, and self-awareness are related to pursuing happiness. Third, through the theme “Social Change and Technological Innovation,” learners can examine the perception of social relationships and understand the importance of technological progress and knowledge, considering that keywords such as world, future, and society appear frequently in this theme. Consequently, this study can help learners improve their language skills by expanding their vocabulary range through the various topics of Sebasi Talks.
Раціональна факторизація гамільтонових потоків на спряженому просторі до алгебри Лі дробових інтегро-диференціальних операторів та інтегровні гідродинамічні системи типу Бенні
Authors: Гентош Оксана , Прикарпатський Анатолій
Published: September 2023

Для гамільтонових потоків типу Лакса на спряженому просторі до алгебри Лі дробових інтегро-диференціальних операторів розвинено метод раціональної факторизації, який дозволяє отримувати нові інтегровні ієрархії нелінійних дробово-диференціальних динамічних систем на алгебрі Лі звичайних інтегро-диференціальних операторів і нескінченні послідовності їхніх законів збереження. За допомогою перетворення Беклунда показано, що система двох таких потоків для пари дробових інтегро-диференціальних операторів, пов’язаних перетворенням подібності, еквівалентна системі двох еволюційних рівнянь для дробових диференціальних операторів, що задають відповідну раціональну факторизацію, знайдено гамільтонове зображення для цієї системи еволюційних рівнянь. Встановлено, що її квазікласичним наближенням є система двох еволюційних рівнянь для дробових символів у вигляді поліномів за дробовим степенем деякого комплексного параметра. Метод використано для побудови нової інтегровної ієрархії нелінійних дробово-диференціальних систем на алгебрі Лі звичайних інтегро-диференціальних операторів та нескінченної послідовності її законів збереження, а також нової інтегровної ієрархії гідродинамічних систем типу Бенні як її квазікласичного наближення.
