Diseño estático y sísmico de túneles superficiales en suelos blandos
Authors:   ,   Universidad del Desarrollo, Medina Molina Luis Felipe
Published: April 2024

En la práctica de la ingeniería aún existe un nivel de incertidumbre en el diseño sísmico de túneles debido a la falta de regulaciones y normativas específicas para cada ambiente sísmico. La motivación de esta investigación es la evidencia en las ultima décadas de daños a causa de terremotos en este tipo de estructuras (p.ej. Dowding & Rozan, 1978; Owen & Scholl 1981; Power et al., 1998; Wang et al., 2001; Yashiro & Kojima 2007). Si bien los daños ocurridos han sido menores a los causados en estructura superficiales, estos no dejan de ser significativos y riesgosos debido principalmente a la importancia que estas estructuras subterráneas tienen en el transporte de personas. El objetivo de esta investigación es responder a la pregunta: ¿Un túnel poco profundo correctamente diseñado para resistir cargas estáticas puede soportar sismos severos sin daños significativos?, lo cual permite probar un diseño estático bajo condiciones de cargas dinámicas asociadas a movimientos sísmicos. Para llevar a cabo el objetivo de esta investigación primeramente se realiza una revisión bibliográfica de los métodos constructivos de túneles y de cálculo para el diseño estático del revestimiento de túneles en suelos. Además, en este estudio se construyó un modelo de elementos finitos 2D con un túnel circular de 6m de diámetro enterrado a 12m de profundidad en un depósito de arena media densa sin presencia de nivel freático, apoyado sobre un semi-espacio elástico. El modelo se resuelve por medio de la herramienta de elementos finitos OpenSees y considera la secuencia constructiva del túnel, una ley constitutiva no lineales para el arena, y seguido de un análisis dinámico para simular los efectos de un sismo severo (e.g., periodo de retorno de 500 años) y un sismo excepcionalmente severo (e.g., periodo de retorno de 2500 años). Finalmente, a través del análisis de resultados y una propuesta de diseño estático se valida la pregunta de investigación para un túnel sometido a sismos de gran intensidad

Meta Heuristic Algorithm Based Novel Dstatcom Architecture for Power Quality Improvement
Authors: Kumar N. V. Vinay , Manohar Tenepalli Gowri
Published: April 2024

Electric utility systems are increasingly favoured as local energy systems due to their ability to integrate renewable energy, improve energy efficiency, and enhance the resilience of the power grid. However, while these benefits are significant, they also present certain complexities related to control and power quality (PQ). PQ is crucial within utility systems to ensure the proper functioning of connected devices and the overall health of the system. Therefore, both voltage quality and current quality are of utmost importance. Control strategies combined with advanced power electronics devices (PED) provide a robust framework to address PQ challenges. This paper introduces a novel approach for constructing a distributed Static Synchronous Compensator (DSTATCOM) utilizing innovative 125-level asymmetric multilevel DC link inverters to enable multilevel operation. A modified 125-level multilevel inverter aimed at enhancing power quality is proposed herein. By employing a minimal number of components, this inverter can generate 125-level voltages per phase, serving as a DSTATCOM to address power quality issues such as sag, swell, and harmonics. Bidirectional DC-DC converters are employed for purposes other than just providing power to the inverter's DC connections replacing DC sources. Additionally, the Coati Optimization Algorithm (COA), a newly introduced metaheuristic approach inspired by observed behavioural patterns in coatis in their natural habitat, is presented. COA is designed to emulate two primary behaviours of coatis: (i) their hunting strategy when pursuing iguanas and (ii) their evasion tactics when confronted by predators. To validate the effectiveness of the Coati Optimization algorithm, simulation is carried out with Matlab Simulink, and the outcomes of the simulation for the proposed scheme are provided in this paper. The efficacy of Solar-PV integrated 125-level asymmetric multilevel DC link inverter in enhancing power quality by adhering to the IEEE-519 Standards is demonstrated.

Теоретико-методологические аспекты изучения социальных детерминант конфликтов в переходном обществе
Authors: Тао Цзыюань , Милецкий В.П.
Published: April 2024

Статья посвящена анализу роли диалектико-материалистической методологии в изучении и выявлении социальных источников, объективных причин и факторов, детерминирующих социально-экономические, политические, межнациональные и другие конфликты в странах, входивших до начала 90-х гг. XX в. в мировую систему социализма. Освещен объясняющий потенциал диалектико-материалистической методологии в раскрытии социальных детерминант (источников, причин и факторов), обусловливающих возникновение многочисленных социальных конфликтов в этих странах. Специальным предметом анализа являются социальные детерминанты современных конфликтов в китайском обществе, частично вызванные маоистскими реформами в КНР, а также объективно обусловленные модернизацией всего китайского общества, которую инициировал и возглавил в конце 70-х гг. XX в. выдающийся реформатор Дэн Сяопин после кончины Великого кормчего Мао Дзэдуна. В результате модернизации в Китае построен рыночный социализм с китайской спецификой, в условиях которого сохраняются объективные причины и другие социальные детерминанты, обусловливающие разнообразные социально-экономические, политические, межнациональные и другие конфликты, которые достаточно решительно и планомерно старается разрешать нынешнее руководство КНР. Проведенное исследование позволило установить, что возникновение конфликтов на пространстве бывшей мировой системы социализма тесно связано с переломными историческими событиями, которые и выступают социальными детерминантами международных конфликтов. В большей мере конфликты в современном китайском обществе обусловливаются неоднозначными маоистскими инициативами («Большой скачок», культурная революция и др.), а также сложностью процессов модернизации постмаоистского Китая под руководством Дэн Сяопина в конце ХХ в. и других лидеров КНР в начале ХХI в.
Семиотическая модель слова Туора (якут.) = Крест
Authors: Попова Г.С.
Published: April 2024

В наступивший век информационной культуры наряду с передовыми коммуникативными технологиями стало необходимо обращение к истокам слова как знака и символа культуры, дающим современному человеку ключи к их скрытым смыслам. Происходит актуализация слов из арсенала религиозной культуры, что подвигло нас обратиться к семиотике слова Крест, вошедшего в семиосферу языка саха и вытеснившего практически равнозначное с ним слово Туора. В условиях существующего двоеверия (сохранения языческого мировоззрения и принятия православного христианства) в современном якутском социуме наблюдается возрастающий интерес к смыслам и ценностям региональной культуры, в основном состоящей из элементов этнических культур коренных народов и укоренившегося русского населения. Целью исследования является составление семиотической модели слова Туора = Крест, способной раскрыть перед современными пользователями различного рода обереги, содержащие знак равного креста, их истинный смысл. Рассмотрены синтактика, семантика, сигматика и прагматика слова Туора = Крест. Методология и методы исследования включают в себя семиотический подход и методику составления семиотической модели слова, методы теоретического анализа научной литературы, логического анализа, методы работы со словарным материалом, сравнение, сопоставление и обобщение. Перспективы исследования предполагаются в дальнейших разработках ­подобного направления в традиционном контенте семиосферы и в популяризации семиотических знаний и навыков анализа среди населения в условиях естественного семиозиса и тем самым повышения культуры речи и мышления современной этнической языковой личности.

Authors: Молчанова Л.А.
Published: April 2024

В основу работы положено учение К.Г. Юнга о коллективном бессознательном как фундаменте человеческой психики. Анализ теории социогенеза Ю.И. Семенова помог наполнить реальными фактами утверждение К.Г. Юнга об архетипах как концентрации ­доисторического опыта человечества, а воршудный комплекс удмуртов, сохранивший черты ­глубокой архаики, подтвердил доисторические корни и социальную семантику костюмных узоров. В результате исследования удалось понять и объяснить многие явления, идеи, образы, мифологические сюжеты и символы, ставшие универсальными. Эта фундаментальная общечеловеческая символика проявляется у каждого народа по-­своему. В работе выделены основные сюжетные композиции и геометрические элементы, ­составляющие орнамент удмуртской одежды и на примере удмуртских костюмных узоров предпринята попытка осмыслить и понять в чем уникальность орнаментики каждого ­этноса и то, как сочетание универсальных символов, складываясь в орнамент, становится одним из главных этнических маркеров.

Published: April 2024

PURPOSE. To study the influence of the illuminance level of test objects on the resolution of the visual analyzer in patients with primary open-angle glaucoma (POAG) and age-related macular degeneration (AMD), and assess the possibility of using the obtained results for early diagnosis of these eye diseases.

METHODS. Visual acuity (VA) under controlled illumination conditions (from 50 to 400 lx) of test objects was assessed using the developed device in three groups: in 50 healthy subjects aged 37.08±10.19 years without ophthalmic pathology (group A), in 50 patients with early (Ia and IIa) stages of POAG aged 47.16±8.28 years (group B) and 50 patients aged 46.08±4.56 years (group C) with dry form of AMD (initial stage).

RESULTS. With an increase in the illumination of test objects (IT) from 50 to 400 lx, the VA of healthy individuals significantly increases on average by δ=0.32 (from 1.0±0.22 to 1.32±0.24, p<0.01), while in POAG the increase in VA with an increase in IT is much less pronounced, averaging δ=0.12 (from 0.9±0.20 to 1.02±0.26, p<0.05). At the same time, starting from IT 150 lx and above, the differences between the values of VA in the control group and in the group of patients with POAG of the initial stages become significant (p<0.05). VA of patients with AMD with increasing IT practically does not change, remaining at a stable level: δ=0.04 (from 0.76±0.20 to 0.80±0.26, t=0.66, p>0.5). At the same time, the VA values in this group of patients for each illumination level are significantly lower (p<0.05) than the corresponding VA values in the control group (group A).

CONCLUSION. The revealed regularities can be used for early diagnosis of the pathological process: an increase in VA at the maximum level of IT relative to the initial value by less than δ≤0.2 indicates pathology of the optic nerve (POAG), and the absence of significant changes in VA with an increase in IT (minimum values of δ) is characteristic of the pathological process in the macula (AMD).

Sustainable composites based on polypropylene and clay
Authors: Pereira Patricia , Libano Elaine , Azevedo Hannah Maria , Faria Albertran
Published: April 2024

The production and consumption of plastic materials have been increasingly studied, since the excessive use of its raw material, oil, and its incorrect final destination can cause serious damage to the environment. For this reason, plastic recycling has been frequently used due to its economic, social and ecological viability. Due to reprocessing, plastics lose properties with each recycling cycle. To optimize the properties of plastics, which are often recycled, natural fibers are mixed with these materials, forming composites. Polymeric composites are increasingly used in a wide range of applications due to their excellent physical-mechanical properties. Recycled HDPE composites were obtained in a twin-screw extruder, with three different fibers in the presence and absence of compatibilizer. Overall, the presence of the fiber promoted a reduction in impact resistance and thermal deflection temperature. On the other hand, it provided an increase in the softening temperature of the composites. Considering the results obtained, the PEZMA composite resulted in a material with greater impact resistance and a higher softening temperature.

Published: April 2024

Introduction: Advances in medicine have provided the possibility of organs and tissues transplantation for therapeutic purposes. Transplant patients, in addition to immunosuppressive therapy, mostly undergo treatment for other comorbidities, and this polypharmacy makes the role of the pharmacist extremely important to ensure patient safety and adherence. Through pharmaceutical recommendations, the professional can reduce morbidity and mortality and thus reduce healthcare costs. Methods: This is an observational, retrospective descriptive study, carried out from January 2021 to December 2022, aiming to analyze the economic impact of pharmaceutical recommendations made in a liver transplant unit of an university hospital. Data collection took place from May to August 2023 through the institution’s clinical pharmacy database. The economic impact was classified as effectiveness increased (EI), cost reduction (RC), and avoided risk (AR) calculated through a methodology developed and adapted to the study’s reality. Medication acquisition costs were verified through the hospital’s own system, and the values were adjusted according to inflation in June 2023. Results: A total of363 pharmaceutical recommendations (PR) were conducted, of which the EI represented 64% (n = 231), followed by RC (20%, n = 72) and risk avoided (16%, n = 60). The total resulting value corrected by the Índice Nacional de Preços ao Consumidor Amplo (IPCA) was R$ 179,223.31, with the AE at R$ 140,414.04 and the RC at R$ 38,809.27. Conclusion: The importance of the clinical pharmacist in the multidisciplinary team is evident through the improvement of patient monitoring and health condition management. Through this study, we can perceive that the PR presented had a considerable financial impact, and, through the optimization of pharmacotherapy for transplant patients, an increase in therapeutic EI was obtained. The importance of developing further studies showing the impact of the quality of care provided by the pharmacy’s performance is clear, to further highlight the importance of this field for healthcare assistance.

Introdução: O transplante renal . a terapia padr.o ouro para doença renal crônica (DRC) em estágio final. Entretanto, aspectos relacionados às características do doador e do receptor, à técnica cirúrgica, ao protocolo de imunossupressão e comorbidade podem impactar a sobrevida do enxerto. Objetivos: Avaliar os fatores associados à sobrevida do enxerto em pacientes pediátricos submetidos ao transplante renal. Métodos: Estudo descritivo do tipo coorte retrospectivo que incluiu todos os pacientes de 1 a 18 anos submetidos ao transplante renal na Unidade Renal Pedi.trica do Instituto de Medicina Integral Prof. Fernando Figueira (IMIP), Recife, Brasil, de janeiro de 2017 a dezembro de 2021, com tempo m.nimo de seguimento de 10 meses, totalizando 51 pacientes. O estudo foi aprovado pelo Comitê de Ética e Pesquisa do IMIP sob o CAAE: 52023921.1.0000.5201. Resultados: A mediana de idade dos pacientes ao transplante renal foi de 12 anos (9-13), sendo 27 (52,9%) do sexo masculino e oito (15,6%) com menos de 5 anos. As principais etiologias da DRC foram as anomalias congênitas do rim e do trato urinário (n = 25; 49%). Quanto ao transplante renal, 49 (96,1%) foram de doador falecido e a mediana do tempo de seguimento foi de 32 (14-42) meses. Após o transplante, 58% da população eram hipertensos, enquanto 80,4% apresentavam dislipidemia. As taxas de sobrevida do enxerto e do paciente em 5 anos, avaliadas pela curva de Kaplan Meier, foram, respectivamente, 86,3 e 90,2%. Sete pacientes (n = 5) perderam o enxerto, sendo a causa mais frequente a trombose de veia renal. As causas não glomerulares de DRC mostraram menor sobrevida do enxerto quando comparadas .s causas glomerulares (log rank p = 0,010). Conclusão: As taxas de sobrevida do enxerto e dos pacientes em nossa casuística assemelham-se aos dados nacionais e mundiais. As causas mais frequentes de perda do enxerto foram os eventos tromboembólicos. Além disso, observamos elevada prevalência de hipertensão e dislipidemia. Esses resultados nos direcionam para estabelecer estratégias para melhorar a sobrevida nos transplantes renais pediátricos.

The purpose of this study was to count the number of human immunodeficiency virus (HIV) patients receiving antiretroviral therapy (ART) who were also infected with tuberculosis (TB) and to evaluate the patients’ changes in certain biochemical parameters at the Federal Medical Centre in Owerri, Imo State. For this study, 350 HIV-positive patients between the ages of 20 and 79 years old who gave their consent were enrolled. National serial algorithms (Determine, Unigold, and StatPak) were utilized for HIV testing, whereas the GeneXpert machine was used for TB testing. While 4 ml of blood was collected in simple vials and the serum used for biochemical analysis, the biochemical analyses were performed using autoanalyzers. The risk of having both TB and HIV was highest in people aged 70 to 79 (31.11%) and lowest in people aged 50 to 59 (10.0%). According to sex, ladies (15.7%) had a greater prevalence of co-infection than males (14.3%). Between ART and non-ART individuals in this study, the results of the biochemical examinations showed that the ART group’s (test subjects’) kidney indicators, urea, and creatinine, as well as their liver enzymes (AST, ALT, and ALP), were statistically higher (P < 0.05) than those of non-ART patients (control group). TB co-infection is more likely to affect elderly HIV-positive individuals due to their weakened immune systems by nature. Additionally, people with HIV who are not on ART run the risk of developing opportunistic infections as well as anemia. In addition to the administration of highly active antiretroviral therapy (HAART), they should be managed with additional caution. Antiretroviral medications have the potential to negatively impact vital organs like the kidneys and liver, necessitating therapeutic drug monitoring. To ensure patient compliance, more measures need to be taken by those in charge of managing these patients.

This paper introduces a new statistical distribution called the Neutrosophic Extended Rayleigh Distribution (NERD), which is specifically developed to handle uncertainty commonly found in industrial applications. We conduct a comprehensive examination of the statistical characteristics of NERD, including important measures such as the quantile function, moments, moment generating function, mean deviation, skewness, kurtosis, reliability measures, uncertainty measures, distributions of order statistics, and L-moments. Parameter estimation is conducted by maximum-likelihood estimation within a neutrosophic framework, guaranteeing resilient inference in practical situations. Through the application of NERD to actual industrial datasets, we evaluate its adaptability and efficiency in simulating industrial processes. A real case study of Al-Kharj region demonstrates the higher performance of NERD. This research highlights the capacity of NERD to greatly improve productivity and efficiency in several industrial sectors.

An element X in a ring R is called idempotent if it equals its square. In this paper, we study the idempotent elements in the 3-cyclic refined neutrosophic ring of integers and 4-cyclic refined neutrosophic ring of integers, where we compute all idempotents in those two rings by solving many different linear Diophantine systems which are generated directly from their the algebraic structure. On the other hand, we use the same Diophantine systems to compute all 2-potent 3-cyclic, and 4-cyclic refined neutrosophic integer elements.

Published: April 2024

This paper provides an in-depth analysis of the dilemmas and paths currently faced by rural revitalization under the digital governance framework, using Xi'an, China, as an example. Rural revitalization is an important agenda in many developing countries, where integrating digital technologies into the governance process presents opportunities and challenges, focusing on how to use digitalization, a key component of modern governance, to promote socio-economic development in rural areas. This paper aims to reveal the complexities involved through analysis. The study is based on a mixed-methods approach, incorporating qualitative data from unstructured interviews with residents, as well as quantitative data from surveys and regional economic reports. It includes technology gaps, infrastructure constraints, digital literacy of the rural population, and how governance policies are adapted to local needs that affect the implementation and effectiveness of digital governance in rural revitalization. The study also explores the relationship between digital governance and rural revitalization, the relevance of digital governance ruralization, an analysis of rural digital governance, and rural digital governance practices. Ultimately, the thesis suggests potential ways to solve these dilemmas. And, it emphasizes the necessity that digital talent cultivation should be increased, new types of infrastructures should be improved, a rural governance system should be constructed, and policy frameworks for narrowing the urban-rural digital divide should be developed. This study contributes to the understanding of rural revitalization in the era of digital governance and provides insights into sustainable rural development and digital transformation. At the same time, the study results in the Xi'an region case may provide experience in solving similar situations globally.

Nowadays, the employment situation is grim, and the postponement and reemployment of college students have become the mainstream employment solutions. School-enterprise cooperation and university business incubation are particularly important at this juncture. From the perspective of organizational sociology, it is a win-win way for enterprises to place talent training before universities. In this process, there will be institutional construction born from the perspective of new institutionalism, emphasizing three institutional elements: regulatory, normative and cultural cognitive [1]. There are both restrictions and constraints on talents within the framework, as well as rewards based on prospects and future. In the existing research in China, many scholars focus on the dilemma, relatively critical and examine it; but there is a lack of dismantling and research on extremely excellent cases. Therefore, the author conducts research through the new institutionalism perspective of organizational sociology, giving full play to its interdisciplinary (including sociology, economics, psychology, etc.) many roles, so that organizational sociology, a knowledge so rich and connotative, can complete a complete analysis and study through composite materials, and provide some insignificant reference experience and significance for the field.

Maymun çiçeği, ağırlıklı olarak Orta ve Batı Afrika'da bulunan ve maymun çiçeği virüsü enfeksiyonundan kaynaklanan viral bir hastalıktır. Bulaşma, enfeksiyon kapmış kişilerle yakın temas yoluyla meydana gelmektedir. Grip benzeri semptomlar ve deri döküntüleri şeklinde kendini göstermektedir. Çoğunlukla su çiçeği veya kızamığa benzer ve dolayısıyla yanlış teşhis riskini arttırmaktadır. Etkili tıbbi müdahale için zamanında ve kesin tanı çok önemlidir. Son zamanlarda, derin öğrenmeye dayalı transfer öğrenme yöntemleri, maymun çiçeğini benzer hastalıklardan doğru bir şekilde ayırt etmek için umut verici bir araç olarak ortaya çıkmıştır. Bu çalışma, tıbbi görüntülerden ilgili özellikleri çıkararak sağlam teşhis modelleri oluşturmak için VGG16, ResNet modelleri, Xception, Inception modelleri, DenseNet121 ve DenseNet201 dahil olmak üzere önceden eğitilmiş evrişimsel sinir ağlarından yararlanmaktadır. Bu modelleri değerlendirmek için Kaggle'daki iki sınıftan (MaymunÇiçeği ve diğerleri) oluşan "Maymun Çiçeği Cilt Lezyonu Veri Seti" kullanılmıştır. Deneysel bulgular, DenseNet201 modelinin %95.56'ya ulaşarak en yüksek sınıflandırma doğruluğuna ulaştığını ve mevcut literatürle karşılaştırıldığında etkinliğini öne çıkardığını ortaya koymaktadır.

College students are among the most strongly affected by COVID-19 because of uncertainty regarding academic stress, future careers, and social life during college. This study used a descriptive correlational design to examine the influence of hope as a moderator on the relationship between academic stress and coping mechanisms among college students during the COVID-19 pandemic. There were three hundred five (305) college student participants that were selected who are currently enrolled from a Higher Education Institution in Region III, with the age range of eighteen (18) to twenty-two (22). Using moderated regression analysis, results showed that there is a significant influence of hope as a moderator on the relationship between academic stress and coping mechanisms among college students in the time of the COVID-19 pandemic. Of the four dimensions, none of significantly influenced the relationship between academic stress and coping mechanisms among college students during COVID-19 pandemic. In accordance with this, the researchers suggest expanding the study’s scope beyond educational settings. Although the researchers did not include in the objectives to look for the agency and pathways, it is recommended to conduct further study to explore these aspects.
Orientation and application of gamification as teaching learning method by medical physiologists in India

Published: April 2024

Background: Gamification, the integration of game elements into non-gaming contexts, has gained significant attention in education, including medical education. Researches revealed that gamification elements such as points, badges, levels, and feedback are commonly used in higher education. Gamification is seen as a tool that can help millennial and Gen Z students, who prefer social learning ecosystems, in competency development and contextual learning. A review of gamification-based learning tools in both preclinical and clinical settings highlighted heightened student engagement and superior educational outcomes, but competitive gamification yielded unexpected results, with students spending limited time and resisting competitiveness.

Aims and Objectives: This paper presents a cross-sectional study conducted in India to assess the orientation and application of gamification among faculty members of Medical Physiology. The study aimed to identify the advantages, challenges, and potential of gamification in enhancing the quality of medical education in India.

Materials and Methods: The authors addressed the deficiency in the orientation and application of gamification tools in medical education by conducting a questionnaire-based cross-sectional study among medical physiologists in various Indian institutions and colleges.

Results: Results showed that approximately 25% of the faculty members surveyed in India were oriented toward gamification, with slightly more orientation among junior faculties and those from northern India. There were regional variations in the use of specific gamification elements, such as points and badges, letterboards, and storyline elements.

Conclusion: The study highlighted a promising trend of gamification adoption among medical physiologists, while also noting that a significant portion of faculty members remained unoriented and had yet to explore the benefits of gamification in medical education. The paper emphasized the need for proactive promotion and application of gamification tools to enhance teaching and learning methods in medical education.
