ВНЕЭСТЕТИЧЕСКАЯ ЖАНРОВАЯ ФУНКЦИЯ БЫЛИНЫ КАК ОСНОВАНИЕ ДЛЯ МОДЕЛИРОВАНИЯ ИНВАРИАНТА ЭПИЧЕСКОГО СЮЖЕТА
Authors: Миронов Арсений Станиславович
Published: August 2023

Аннотация. В статье аргументируется, что сводный текст того или иного былинного сюжета может быть составлен на основе его аксиологического анализа. Вопреки распространенному представлению (В. Я. Пропп, Б. Н. Путилов), вариативность русских эпических песен носит ограниченный характер, что определяет их ценностно-семантическую цельность, внутреннюю связность, имеющую, по мнению автора статьи, внеэстетическую функцию: былины были призваны укрепить – или, напротив, девальвировать – определенные ценностные категории в сознании слушателей. Сказанное позволяет вывести аксиологическую формулу для того или иного былинного сюжета и, как следствие, выделить его структурно значимые эпизоды из различных записей (включая записи поздние и фрагментированные), а также составить на основе подобных эпизодов результирующий сводный текст. В качестве примера такого текста приводится сделанная автором статьи реконструкция былинного сюжета «Василий Буслаев и новгородцы».
Abstract. The article states that a consolidated text of a certain bylina plot could be compiled through this plot's axiological analysis. Contrary to the widespread idea (originated from the works of V. Ya. Propp and B. N. Putilov), the variability of Russian epic songs is rather limited, which determines the latter's value-semantic integrity and inner coherence, presupposing, according to the author of the article, an extra-aesthetic function: bylinas were intended to strengthen – or vice versa to devalue – certain axiological categories in the listeners' consciousness. This allows one to derive a formula for a certain bylina plot, to choose this plot's structurally significant episodes from different bylina records (including the ones of late and fragmented nature), and then to compile a resulting compendium on their basis. By way of illustration, the author of the article suggests his reconstruction of the plot «Vasily Buslaev and the Novgorodians».

Published: August 2023

Background: The severe coronavirus disease 2019 (COVID-19) induces widespread inflammatory responses that are attempted to be managed by the administration of anti-inflammatory drugs, along with antiviral drugs and respiratory support. This clinical trial study investigated the effect of short-term and low-dose methylprednisolone on the clinical outcome and radiological improvement of admitted patients with severe COVID-19. Methods: In this randomized clinical trial, two strains of patients with severe pneumonia of COVID-19 were evaluated before and after the use of corticosteroids. Inclusion criteria were age over 18 years, definitive case of COVID-19 based on positive reverse transcription polymerase chain reaction (RT-PCR) for severe acute respiratory syndrome coronavirus 2 (SARS-COV-2), and arterial oxygen saturation (SaO2 )<93%; furthermore, at least 7 days and 5 days should be passed since the onset of symptoms and antiviral treatment, respectively. Exclusion criteria were similar to contraindications to the administration of methylprednisolone for short-term injections and pregnancy. Patients received intravenous methylprednisolone succinate (1-1.75 mg/kg/day) for 5 days in addition to treatment based on the World Health Organization (WHO) approved protocol for COVID-19. Finally, demographic characteristics, dyspnea, peripheral oxygen saturation (SpO2), number of lymphocytes, and computed tomography (CT) scan of the patient’s chest before and after taking corticosteroids were evaluated. Results: The average oxygen saturation of patients increased significantly after taking methylprednisolone succinate (P<0.001). Moreover, dyspnea and pulmonary insufficiency in CT scans improved significantly (P<0.001), and among hematological parameters, only lymphocytes increased significantly (P=0.01). Furthermore, methylprednisolone succinate use had no effect on mortality and length of hospitalization. Conclusion: Methylprednisolone succinate use during the treatment period of COVID-19 improves clinical conditions, CT scan findings, and hematological parameters affected by inflammation, but it does not affect the mortality and length of hospitalization of patients.

Published: August 2023

Introduction: Temporomandibular disorders (TMDs) are the most prevalent non-dental origin orofacial pain conditions affecting the temporomandibular joints (TMJs) and/or orofacial muscles. Photobiomodulation therapy (PBMT) is a conservative way to improve function and reduce symptoms in TMD patients. This systematic review was conducted to update evidence about the effects of PBMT on pain intensity, TMJ movements, electromyography (EMG) activity, pressure pain threshold (PPT), and TMJ sound in patients with TMDs. Methods: A systematic literature search was conducted in Web of Science, PubMed/Medline, and Scopus databases using appropriate keywords and specific strategies from January 2000 to September 2022. Data extraction was done based on the inclusion/exclusion criteria. Results: A total of 40 studies were included. All included studies except one provided information on pain intensity; 27 studies showed a reduction in pain intensity in PBMT groups compared to control groups. Seven out of 15 studies, which reported maximum mouth opening (MMO), showed a greater MMO in PBMT groups than in placebo groups. In addition, the figures for passive maximum mouth opening (PMMO) and active maximum mouth opening (AMMO) in all the studies reporting PMMO and AMMO were higher in PBMT groups. In eight out of ten studies, lateral movement (LM) was greater in PBMT groups. Moreover, in three studies out of four, protrusive movement (PM) was reported to be greater in the PBMT group. Four out of nine studies showed a greater PPT in the PBMT group. Reduced TMJ sounds in the PBMT group were reported in two out of five studies. In addition, in most studies, no difference in EMG activity was detected between the two groups. Conclusion: This updated systematic review showed the promising effects of PBMT on the alleviation of pain and improvement in MMO. Using the infrared diode laser with a wavelength ranging between 780-980 nm, an energy density of<100 J/ cm2 , and an output power of≤500 mW for at least six sessions of treatment seems to be a promising option for treating mentioned TMDs signs and symptoms based on the previously reported findings.

Introduction: Photodynamic therapy (PDT) is applied as an efficient method for preventing the progress of cancers. Light and a photosensitive compound which is known as photosensitizer (PS) are the main parts of PDT. In the present study, molecular events after using PDT in the presence of a super lethal dose of a PS were assessed via protein-protein interaction (PPI) analysis. Methods: Data were extracted from Gene Expression Omnibus (GEO). The gene expression profiles of the treated human Sk-Cha1 cells via PDT were compared with the control cells. Expressed change analysis and PPI network analysis were administrated via Cytoscape software v 3.7.2 to find the critical differentially expressed genes (DEGs). Regulatory relationships between the central DEGs were evaluated and the highlighted genes were identified. Results: The significant amounts of gene expression values were grouped and a few DEGs characterized by tremendously expressed values were identified. EGFR, CANX, HSPA5, MYC, JUN, ITGB1, APP, and CDH1 were highlighted as hub-bottleneck DEGs. EGFR, CDH1, and JUN appeared as a set of SEGs, which play a crucial role in response to PDT in the treated Sk-Cha1 cells. Conclusion: In conclusion, regulatory relationships between EGFR, CDH1, and JUN, which have an effect on the regulation of cellular survival, differentiation, and proliferation, were highlighted in the present investigation.
Interactions of vitamin D with parathyroid glands; an updated mini-review
Authors: Hemmati Hamid Reza
Published: August 2023

Vitamin D is essential for regulating calcium and phosphate metabolism, and its deficiency or excess can significantly affect parathyroid function. The deficiency or insufficiency of vitamin D can lead to increased parathyroid hormone (PTH) production, resulting in secondary hyperparathyroidism. Conversely, adequate vitamin D levels suppress PTH synthesis and maintain normal calcium levels. Dysregulation of this delicate balance can contribute to various disorders such as osteoporosis, renal stones, and skeletal abnormalities. Hence, understanding the complex interactions between vitamin D and the parathyroid glands is important for diagnosing and managing disorders such as primary and secondary hyperparathyroidism.

Published: August 2023

Portuguese SMEs are ‘catching-up’ to the European Commission’s goal of 20% for SME participation in H2020, representing16,7% of allocated funds.. Previous R&D experience, and especially R&D cooperation, have been identified as key determinants of participation in Framework Programmes, such as H2020. Thus, it is important to know SMEs that engage in these experiences and the drivers that lead them to it. This paper seeks to identify why and how SMEs gain collaborative experience with HEIs; what are the organizational characteristics that foster collaboration; the types  of experiences in which SMEs are engaged with HEIs; the obstacles they face when applying for FP funding, and how these can be overcome. Lastly, we aim to draw lessons that foster SMEs’ participation in Framework Programmes. To achieve these goals, we conducted a survey with SMEs that collaborate with HEIs (N = 26), including SMEs that participated in H2020 and SMEs that didn’t. We then complemented the survey with six in-depth qualitative interviews with both FP participants and non-participants.

Authors: Rodriguez Dr. Manuel
Published: August 2023

During the past three years, mathematics educators have had to adjust to the onlineeducationsystemanddevelopnewapproaches,strategies,andpracticestokeepstudents engaged and motivated. Student engagement and motivation have been established in existing research as vital aspects of education. To promote engagement and motivation during the pandemic, mathematics educators have focused on positive working relationships with students, highlighting values such as care and empathy. Mathematics educators have also adopted various technological tools to enhance student engagement and motivation. As institutions have begun to reintroduce face-to-face classes in the post-pandemic era, there is a need to re-examine these approaches, and how they may be sustained or improved. A significant gap that has remained unexplored in the literature is how mathematics educators maintain or enhance student engagement and motivation upon transitioning to face-to-face or hybrid classes in the post- pandemic era. This concept paper is centered on this research gap, with recommendations for theory and practice based on current knowledge regarding higher education students’ motivation and engagement in mathematics.

The State of Philippine-Iran Bilateral Relations, Maximizing Values, Human Potentials and Shared History
Authors: SEVILLA jr Henelito A.
Published: August 2023

The Philippines and Iran are two important players in the geopolitical transition of Asian and the Pacific region. The geopolitical values that these two countries held over many decades exposes them to rivalries and competition among regional and international powers. In some part of history, they became a closed ally to the United States, while regime change in Iran in the late 1970s had created some sort of difficulty for both countries to improve bilateral relations amidst normalization. This paper therefore seeks to investigate existing domestic and external factors that can help explain the underdeveloped state of their bilateral relations. In doing so, the paper advances the idea that although the Philippines and Iran are sovereign and independent countries, the course and direction of their relation since the post-1979 event was heavily affected by the US policy vis-à-vis the Philippines and Iran.

Authors: Alves Hugo de Almeida
Published: August 2023

O presente artigo, tem por objetivo a apreensão das determinações e influências que os diferentes contextos geográficos exercem no processo de construção das “referências” e da identidade juvenil otaku. A cultura otaku nasce no Japão pós II Guerra Mundial. Apesar do intenso processo de imigração japonesa para o Brasil, ocorrido no século XX, é por conta da globalização e do desenvolvimento das Tecnologias de Informação e Comunicação que, no final de 1980 e início de 1990, dado universo cultural encontra a base material ideal para se estabelecer enquanto uma possibilidade de experienciar a juventude entre os brasileiros. Deste modo, participantes de uma “cultura híbrida”, por situarem suas referências globais, a cena otaku se produz e reproduz via espaços concretos (online) e virtuais (offline), uma vez que, o ciberespaço, nada mais é do que uma extensão do próprio Espaço, que funda espacialidades e territorialidades, permitindo a apreensão dos processos constitutivos das Culturas e dos Espaços contemporâneos.

Desde o início da colonização as bacias hidrográficas da cidade do Rio de Janeiro vêm incorporando dinâmicas de transformações antrópicas oriundas do processo de urbanização, com intervenções mais intensas no século XX, tendo efeitos em seus canais fluviais. O presente trabalho visa avaliar os tipos de uso e ocupação do solo que são predominantes nas margens do rio Comprido e sua respectiva relação com a sua drenagem. Os dados utilizados foram adquiridos através do Instituto Pereira Passos que, em ambiente SIG, foram manipulados, gerando o perfil longitudinal do rio Comprido e a cena ambiental de 2018 das suas margens. Posteriormente, os dados foram quantificados e os valores organizados em uma tabela para fins comparativos. Como resultado foi observado que o predomínio da ocupação pelas Áreas residenciais nos locais de menor altitude, e da Cobertura arbórea e arbustiva nas áreas de maior altitude, que se encontram ameaçadas pelas expansões das favelas em direção ao Parque Nacional da Tijuca. Assim, este trabalho pode fornecer subsídio ao poder público no planejamento desta área ambientalmente suscetível.
Os retrocessos no combate à fome e insegurança alimentar na América Latina
Authors: Corado Érica Beatriz Guedes
Published: August 2023

Em 2020, a FAO, disponibilizou dados preocupantes sobre a situação da fome no mundo. De acordo com a organização, mais de 60 milhões de pessoas foram afetadas pela fome desde 2014, de modo que o número de pessoas subnutridas pode ultrapassar 840 milhões até 2030. A situação no subcontinente Latino-americano não apresenta uma tendência contrária à observada em escala global. A FAO estima que, até 2030, cerca de 67 milhões de pessoas na América Latina devem enfrentar a insegurança alimentar, ou seja, 9,5% de sua população, o que representa um grave quadro. A partir disso, o objetivo deste trabalho é compreender quais são os fenômenos sociais, políticos e econômicos que viabilizaram o atual cenário de Insegurança Alimentar na América Latina, tendo em vista que a alimentação é um Direito Humano. Para alcançar os objetivos aqui apresentados, optou-se por adotar uma metodologia qualitativa. No que diz respeitos aos processos metodológicos, a ferramenta escolhida para este estudo foi a pesquisa bibliográfica, além de uma pesquisa documental. Entende-se que, para que haja a garantia da Segurança Alimentar na América Latina, é preciso haver um rompimento com o sistema capitalista que gera a pobreza e assegura o benefício de poucos. Deste modo, a guerra contra a miséria e a fome latino-americanas torna-se, fundamentalmente, a guerra contra o sistema capitalista destrutivo, assim como ao neoimperialismo no Sul Global.

Sebuah desain motor DC magnet permanen NdFeB persegipanjang telah dibuat dan diuji secara ekperimental. Penggunaan gigi rotor magnet permanen persegi panjang dibuat secara berlapis bertujuan untuk meningkatkan torsi motor DC. Pengukuran dan pengujian gaya dan torsi motor DC menggunakan sebuah neraca pegas. Selain itu, pengaturan jarak celah udara dan penambahan lapisan magnet dilakukan untuk mengetahui kinerja motor DC magnet permanen dengan putaran yang bervariasi. Desain motor DC magnet permanen ini memiliki 8 kutub dengan 150 lilitan per kumparan dan susunan 1 - 4 lapisan magnet permanen dengan jarak celah udara dari 1 - 4 mm. Hasil penelitian menunjukkan bahwa semakin banyak susunan lapisan magnet permanen dengan jarak celah udara magnet rotor dan stator yang semakin kecil akan menghasilkan torsi yang semakin besar. Pada pengukuran torsi motor dengan 4 lapisan magnet permanen untuk jarak celah udara 1 mm dengan tegangan medan 50 Volt diperoleh torsi elektris 0,6910 N-m, torsi mekanis 0,027 N-m dengan kecapatan putaran 780 Rpm. Kemudian pada tegangan 60 Volt dengan jarak celah udara 1 mm diperoleh torsi elektris 0,0853 N-m dan torsi mekanis 0,02925 dengan kecepatan putaran 860 rpm.

Penelitian ini bertujuan untuk mengkaji dampak penyambungan PLTS Oelpuah berkapasitas 5 MWP ke SUTM 20 kV, ditinjau dari aliran daya dan besar perubahan tegangan, komposisi pembangkitan, serta faktor daya listrik, ketika PLTS bekerja dalam kondisi cuaca cerah, berawan, dan hujan, dan bagaimana kondisi sistem dengan dan tanpa beroperasinya PLTD LMVPP. Dari hasil analisis diperoleh, profil tegangan pada titik interkoneksi PLTS Oelpuah ke penyulang Oesao dan Gardu Hubung Undana berubah-ubah tergantung kondisi cuaca. Saat cuaca cerah kondisi tegangan pada gardu hubung Undana dan penyulang Oesao stabil namun saat kondisi cuaca berawan dan hujan tegangan distribusi pada penyulang Oesao dan Gardu Hubung Undana mengalami penurunan. Komposisi suplai daya listrik pembangkit juga mengalami perubahan diakibatkan kondisi cuaca. Saat cerah PLTS menyuplai 3,2 MW, PLTD LMVPP menyuplai 12,6 MW, saat berawan PLTS menyuplai 915 kW, PLTD LMVPP menyuplai 15 MW dan saat cuaca hujan PLTS tidak dapat menyuplai daya ke sistem, dan PLTD LMVPP harus menambahh suplai daya listriknya menjadi 16 MW. Saat PLTD LMVPP lepas dari sistem, maka setiap pengurangan komposisi daya pada PLTS akibat cuaca yang berubah tersebut dialihkan ke PLTU IPP. Faktor daya listrik pada titik penyambungan PLTS  yakni di penyulang Oesao, juga dipengaruhi dengan kondisi cuaca yang berubah.

This article presents the design of an innovative photovoltaic solar regulator equipped with a neural MPPT (Maximum Power Point Tracking) control and an advanced battery charge and discharge management algorithm. The main objective of this research is to significantly improve the efficiency of solar energy conversion into electrical energy by optimizing the maximum power point and effectively regulating battery charging and discharging. The neural MPPT control represents a major advancement in the field of solar energy. Unlike conventional algorithms, this approach enables the regulator to adapt to environmental variations, such as fluctuations in sunlight. As a result, the regulator can constantly adjust the maximum power point, ensuring a high efficiency of the solar system. The battery charge and discharge management algorithm is a crucial element in the regulator's design. Effective battery management is essential to maintain a balance between solar energy supply and electrical equipment consumption. Through this algorithm, the battery is kept within optimal charge ranges, thereby avoiding overcharging or excessive discharging, which contributes to prolonging its lifespan. To evaluate the performance of the proposed photovoltaic solar regulator, detailed simulations were conducted using the Matlab/Simulink software. The obtained results confirmed a significant improvement in solar energy conversion efficiency. The combination of the neural MPPT control and the battery management algorithm allows the system to operate optimally, even under changing environmental conditions. The practical applications of this research are diverse. This enhanced solar regulator could be deployed in remote regions without access to the traditional power grid. It also provides an effective solution for rural or isolated areas where solar energy can be a viable energy source, but intelligent management is required to ensure stable electrical supply. In conclusion, this study presents a significant advancement in the field of photovoltaic solar energy, combining a novel neural MPPT control with an advanced battery management algorithm.

The concern generated by the high rate of unemployment among graduates of tertiary institutions has reached a grievous level. This is borne out of the societal disdain for technical education programmes aimed at boosting the competency level of its recipients in both teaching, handling of tools and machines for gainful employment. Considering the dismal level of response to technical education programmes, this study assesses some factors related to enrolment in technical education programmes of Colleges of Education in southwestern Nigeria. Two research questions were drawn to guide the study. A total of 402 academic staff and students were used for the study. The students were randomly selected. A structured questionnaire was used for the data collection with a reliability coefficient of 0.97 using correlational analysis. Findings revealed that poor awareness, incentives, and inadequate facilities discourage and prevent people from enrolling in technical education. Thus, the place of both print and electronic media was stressed in sensitizing the general public about the importance of Technical Education in solving the problems confronting the Nigerian public.

The most successful manufacturers have strategically linked their internal processes to external suppliers and customers in unique supply chains. Manufacturers now recognize the potential of supply chain integration to improve their performance but the lack of deep understanding of supply chain integration to achieve strategic importance is a major challenge to supply chain managers making it hard to be implemented with most confusing supply chain integration with partnerships and collaborations of business partners. Studies on integrated supply chain and its impact on an organization’s overall performance are still unsettled and the area has not been extensively examined. To bridge this research gap, this study examined the effect of integrated supply chain practices on the performance of Fast-Moving Consumer Goods firms in Kenya. The study was guided by the following objectives: to establish the effect of customer integration on the performance of fast-moving consumer goods firms in Kenya, to determine the effect of internal integration on the performance of fast-moving consumer goods firms in Kenya and to examine the effect of supplier integration on the performance of fast-moving consumer goods firms in Kenya. The study was anchored on the following theories: transaction cost economies theory, contingency theory, and the resource-based view theory. The study adopted a descriptive research design, and the target population was 261 employees from 8 departments. The sample size was 158 respondents who were selected through stratified and simple random sampling technique. The study used questionnaires to collect primary data. Data analysis was done using the SPSS   software v.25. A multivariate regression model was used to determine the relative importance of each variable of the study and correlation analysis was carried out to find the relationships between the variables under the study. The study concluded that integrated supply chain practices had a positive and significant effect on the performance of fast-moving consumer goods firms in Kenya at Unga limited. The study recommended that FMCG firms enhance the utilization of supplier integration practices to improve organizational performance. Further, the study recommends that internal integration and customer integration be strategically used as policy tools for coordination, production planning and scheduling, customer order management, and demand planning as this will enhance the overall organizational performance.
