Leadership ethics are a fundamental component in creating harmony and organizational success. The Hindu perspective through the concepts of Tri Hita Karana (THK) and Hastabrata provides a unique view in forming an ideal leader. THK focuses on harmony between humans and God (Parahyangan), fellow humans (Pawongan), and the environment (Palemahan), while Hastabrata offers eight leadership characteristics inspired by natural elements. This article discusses the relevance of these two concepts in modern leadership, using a descriptive-qualitative approach based on literature studies. The results of the study indicate that the application of THK and Hastabrata values ​​is not only relevant in the context of local culture but also provides ethical insight for global leaders. With good integration, these two concepts are able to create leaders who are not only ethical but also visionary and innovative, relevant to the needs of today’s organizations.
Desafiando as sombras a morfogênese de duas favelas em Belo Horizonte, 1967-1982
Authors: Barcellos de Souza Gisela , Gimmler Netto Maria Manoela , Cordeiro Gabriel , Rodrigues Sampaio Andrade Letícia
Published: January 2025

O presente artigo utiliza-se da leitura da morfogênese de duas grandes favelas de Belo Horizonte que surgiram entre 1967 e 1979 para desvelar indícios que possam permitir a compreensão das formas de organização constituídas para a concretização de novas ocupações durante o período da Ditadura Militar (1964-1985). Analisam-se dois casos distintos: a Vila Cemig, cuja ocupação inicial dá-se no final da década de 1960, em gleba de 18 hectares que pertencia à Fundação Tiradentes (Polícia Militar), e a Vila Cafezal, que surge após 1972 em terreno de 17 hectares remanescente da antiga Colônia Agrícola Bias Fortes. A abordagem do artigo considera a morfogênese tanto no concernente à constituição do tecido urbano – rotas matrizes, planejadas e de conexão – quanto no que se refere à sua relação com a estrutura fundiária e a estrutura urbana de modo geral. Conclui-se que ambas revelam indícios de diferentes formas de associativismo e de organizações populares que conseguiram transcender a repressão militar e as políticas de desfavelamento.

Published: January 2025

Background. The public response to the coronavirus pandemic, including their uptake of protective measures, was critical for containing the virus, and this required effective interventions, policy decisions, and public communication that took into account the perspectives of the population. The main goal of the study was to explore public perceptions, behaviors, and well-being of the population of Moscow, Russian Federation, to inform the pandemic response.

Methods. A survey tool originally developed by the WHO Regional Office for Europe with support from the University of Erfurt, Germany, was adapted to the Moscow (Russian Federation) context. Computer-assisted telephone interviews (CATI) were conducted using a stratified, two-core sample of landline and mobile phones. Three waves of data collection took place from mid-May 2020 to mid-June 2020: 1) May 13–18, 2020, n = 1019 people; 2) May 26, 2020 – June 1, n = 1000 people; 3) June 16–24, 2020, n = 993 people.

Findings. The study identified the awareness of Moscow residents about the coronavirus, their perceptions, understanding of the pandemic situation and behavioral responses to measures taken by the authorities to reduce the spread of COVID-19.

Interpretation. Monitoring of public perceptions, behaviors, and well-being allowed a people-centered approach, which took into account population perspectives alongside epidemiological data and economic, cultural, ethical, and structural-political considerations, to become the basis for an effective coronavirus response.

Authors: Savina A. A. , Feyginova S. I. , Zemlyanova E. V.
Published: January 2025

Background. Obesity and associated diseases could substantially affect life expectancy by increasing the risks of premature mortality.

Objective. To evaluate the changes in the age and sex distribution of adult mortality from obesity-associated causes in Moscow from 2011 to 2020 in comparison to the average national indicators.

Materials and methods. The analysis focused on standardized death rates among the adult population, categorized by sex and age groups (aged 20–54, aged 55–59, aged 60 and older).

Results. In Moscow, mortality from atherosclerotic cardiovascular disease significantly reduced, especially in persons aged 20–54. The reduction in mortality rate from cerebral infarction was higher in Moscow, especially in individuals aged 55 and older, across both sexes. Conversely, the incidence of ischemic heart disease mortality in Moscow has risen. The study showed an increase in mortality from endocrine diseases, including type 2 diabetes, which may be partly explained by the revised guidelines for coding primary causes of death. In addition, the dynamic in Moscow was more favorable. The mortality rates from malignant neoplasms in Moscow were 8% lower than in Russia, and mortality trends were rather favorable, both in Moscow and Russia. However, mortality rates and trends vary significantly depending on the type of malignancy.

Conclusions. A favorable trend was observed in mortality from obesity-associated diseases, such as acute cerebrovascular accident (cerebral infarction) and some malignant neoplasms (colorectal cancer and breast cancer in women). The negative trends in mortality from such chronic diseases as ischemic heart disease and type 2 diabetes were observed. Men aged 55–59 have been identified as a risk group for these negative trends. Therefore, it is necessary to expand the preventive measures targeting these at-risk groups.

Diabetes mellitus is a metabolic disorder characterized by an increase in blood sugar due to decreased insulin secretion by pancreatic beta cells or impaired insulin function (insulin resistance) that can lead to microvascular and macrovascular complications. The results of previous studies state that plasma levels of VEGF and IGF-1 are associated with the incidence of diabetic retinopathy and diabetic nephropathy. The examinations carried out include HbA1C using the HPLC method, measurement of VEGF and IGF-1 levels using Bioassay Technology Laboratory ELISA Human IGF-1 and VEGF. Of the 52 patients examined, it was found that 10 type 2 DM were controlled and 42 type 2 DM were uncontrolled. Uncontrolled type 2 DM had a higher VEGF level of 409 (ng/ml) than controlled 391.8 (ng/ml). IGF-1 levels of uncontrolled type 2 DM were higher at 8.8 (ng/ml) than controlled 6.6 (ng/ml). The conclusion obtained from this study is that there is no significant difference in VEGF and IGF-1 levels in controlled and uncontrolled type 2 DM. Controlled type 2 DM VEGF levels are lower than uncontrolled, while controlled IGF-1 levels are lower than uncontrolled. There was no significant difference in IGF- 1 levels with obese and non-obese patients based on Body Mass Index (BMI). IGF-1 levels of obese type 2 DM are lower than those who are not obese.

Authors: Baldonado Jonna F. , C. Espiritu Ma. Nissa
Published: January 2025

Breaking into the male-dominated maritime industry is difficult for female seafarers. This study explored how the potentials of female seafarers can be maximized in the maritime industry.  Having a mixed method research design, the quantitative part employed survey of female seafarers and interview of representatives from different sectors of the maritime industry where these females are employed.   Findings indicate majority of female seafarers experienced resistance from sea-based employment on the belief that seafaring is ascribed for men only. Most respondents aspired to settle in land-based employment. On the other hand, land-based sectors of the maritime industry are accepting female seafarers. Interviewees confirmed available positions which suitably fit the qualifications of female graduates. To fully maximize their potentials and prepare them for land-based positions, interventions such as taking additional trainings and seminars and pursuing higher studies were suggested.

Published: January 2025

Enhancing the chances of survival for cancer patients requires early brain tumour identification. This study suggests a federated learning-based method to deal with classification problems caused by overfitting. With the use of the BRATS 2019 and 2020 datasets, the method successfully divides and categorises brain tumours. Data preprocessing involves min-max normalization, followed by CNN segmentation from MRI images. Extracted features undergo shape, texture, and Resnet-50-based feature extraction. These features are then inputted into an LSTM classifier, utilizing Federated Learning for improved classification. Findings indicate that the suggested FL utilizing the CNN-LSTM model outperforms other techniques like U-net and ensemble models, achieving high accuracy: 99.59% on BRATS 2019 and 99.61% on BRATS 2020 datasets.

PROBLEMS OF ENVIRONMENTAL SECURITY AND WATER SUPPLY NEEDS IN THE CENTRAL ASIAN REGION
Authors: Mihranyan A. A.
Published: January 2025

he last decade in the Central Asian region has been characterized by a steady trend of increasing fresh water needs due to the expansion of agricultural activities and the growth of population consumption. At the same time, the growth of consumption is ensured exclusively by increasing the anthropogenic load on available water resources, which causes a multiple increase in the risks of environmental disasters and problems with water supply and ensuring water security of the countries of the region. The article uses the method of complex assessment (balance method) of assessing the level of water resources availability in the context of countries, content analysis of regulation of water use of transboundary rivers, factor analysis of the growth of regulation of water flows of the main rivers (Amu Darya and Syr Darya basins, hereinafter abbreviated as BAM) and project analysis of the growth of anthropogenic pressure on the resource base of the region. The study notes that the uncoordinated use of water resources for national development and projects to overcome the environmental problems of shallowing of the Aral Sea only lead to an aggravation of the situation. The conclusions are based on the assessment of projects and strategies for overcoming the environmental catastrophe of the Aral Sea and the construction of new artificial water drainage infrastructure in the countries of the lower reaches of transboundary rivers.

Published: January 2025

When tracing the epistemological but also thematic development of metaphor studies in Egyptology, what can be seen is a change from a typological perspective, which sought to categorize both motifs and metaphor types, to a more cognitive perspective, which was more interested in the processes behind the linguistic phenomena. In the last few years there has also been increased interest in the development of metaphors in pan-textual as well as multimodal perspective and in the usage and extent of metaphors in all range of phenomena, such as textual, graphemic, and even pictorial media.

Sugarcane bagasse, a by-product of sugar production, emerges as a promising source of cellulose, offering avenues for value addition and waste reduction within these industries. Three extraction methods were evaluated: soxhlet extraction using ethanol, kraft pulping with NaOH/Na2S, and iCEL machine producing cellulose, extractive, and lignin. Quantitative analysis reveals that soxhlet extraction yields the highest purity of cellulose (75.86±1.54%), followed by the iCEL machine (50.20 ± 12.49%), while kraft pulping shows comparatively lower purity (48.42±3.95%) due to incomplete delignification. Morphological examination indicates that soxhlet extraction preserves cellulose’s native properties, including its white colour and fibrous morphology akin to raw cotton.

In contrast, kraft pulping induces degradation, leading to yellowing and lignification of the cellulose. Fourier transform infrared spectroscopy confirms the presence of characteristic cellulose peaks in all samples, with additional peaks indicating residual non-cellulosic components, especially in kraft cellulose. Soxhlet extraction is optimal due to its simplicity, higher purity, and non-destructive nature. Despite its industrial prevalence, kraft pulping exhibits lower efficiency in cellulose extraction. While the iCEL method shows promise, further optimization is needed to enhance consistency. Future research directions may include adapting soxhlet parameters for nanocellulose production and characterizing material properties for diverse applications. Economic feasibility and environmental impact assessments are crucial for the commercialization of lab protocols, thereby supporting sustainable cellulose production from abundant agricultural residues like sugarcane bagasse. In conclusion, this study underscores the importance of exploring efficient and sustainable methods for cellulose extraction from sugarcane bagasse, with implications for promoting circular economy principles and fostering sustainable development across agricultural, forestry, and plantation sectors.

Authors: Marotse Violet
Published: January 2025

The purpose of this study is to examine the effectiveness of communication strategies adopted by the interpreters of sermons in the Pentecostal churches in Vihiga County. The analysis of the effectiveness of the communication strategies was anchored on Nida’s translation theory, which underscores the significance of the interpretation setting, purpose of discourse and words' capacity to assume different meanings in different contexts, which compel interpreters to thoroughly review the translated work in order to produce effective interpretation. Descriptive research design was employed, and preachers, interpreters, and congregants from Pentecostal churches in Vihiga County constituted target population. Audio-video recording, interview guide and structured observation guide were employed in data collection, while thematic content analysis was employed in data analysis. The results showed that the interpreters of the sermons in the Pentecostal churches commonly employed lexical addition, repetition, rewording, shift of footing, stage movement, restatement, use of pause, intonation, pitch, pace and emphasis to maintain the preaching rhythm and mimicry as the communication strategies. The study concludes that the communication strategies were effective in enhancing the transmission of the message during sermon delivery. As a result, the study recommended that the interpreters should be adequately trained in sermon interpretation to enhance their ability to deal with the dynamics of interpretation in the Pentecostal churches. This study is significant to the entire Pentecostal church community, as well as preachers, interpreters, researchers, and scholars who are concerned about the effectiveness of communication strategies adopted to enhance the transmission of the message during sermon delivery.

Abstract: According to F. Furtado and A. Singh (2021), movie recommendation systems aim to assist viewers by suggesting movies to watch, thereby avoiding the time-consuming and complex process of selecting from a vast library of movies, which can number in the thousands or even millions. This article seeks to reduce human effort by recommending movies based on user interests. To address these challenges, we propose a technique that combines content-based and collaborative approaches. This method produces more precise results than systems that rely solely on content-based methods. Content-based recommendation systems are limited to individual preferences and do not recommend items outside the user’s immediate interests, restricting exploration. To overcome these limitations, we developed a system that addresses these concerns. The proposed movie recommendation system uses Cosine Similarity to suggest movies like the one chosen by the user. While existing algorithms generate recommendations, they often fail to answer the critical question, “Is this a film worth watching?” To enhance the overall experience, our system incorporates sentiment analysis of selected movie reviews using machine learning techniques. This study employs two supervised learning approaches, Naïve Bayes (NB) and Support Vector Machine (SVM), to improve accuracy and efficacy. A comparison of the two methods reveals that SVM achieved an accuracy score of 98.63%, while NB scored 97.33%, as reported by N. Pavitha et al. (2022). The project integrates a sentiment analysis module into the movie management system to enhance decision-making and user experience. The Naïve Bayes approach is used to classify and evaluate user reviews and feedback into positive, negative, and neutral categories. This analysis provides insights into audience preferences, overall satisfaction, and movie reception. The system utilizes this information to refine movie recommendations, analyze trends, and enhance content selection, all of which contribute to a more personalized user experience. The system is evaluated using the ISO 25010 framework, focusing on functionality, reliability, usability, effectiveness, and robustness. Findings show that respondents actively participated in the review process across multiple domains. Key results indicate high satisfaction levels in terms of ease of use, interface design, and system performance. Feedback also highlighted areas for improvement, such as optimizing loading times and enhancing specific features for a smoother user experience. Overall, the findings reflect positive engagement with the system, demonstrating its effectiveness in meeting user needs while identifying opportunities for future enhancements.

The purpose of this study is to analyze the satisfaction of general high school students with subject selection according to the high school credit system. For the efficient operation of the system ahead of the full implementation of the high school credit system in 2025, it is necessary to analyze the satisfaction of students who are actually experiencing it. Accordingly, a survey was conducted on 761 second-year students of G city's general high school, who are subject to the high school credit system, asking about the degree of satisfaction with the autonomy, purpose, and diversity of subject selection according to individual differences by gender, selection series, and academic achievement. In the average score of the selection criteria scale factor, the recommendation of others was the lowest and career development was the highest, and the degree of autonomy of choice was analyzed as an important variable affecting subject selection criteria and satisfaction. There were significant differences in satisfaction according to individual differences by gender and academic achievement. Unlike the subject selection criteria in gender, a significant difference in satisfaction can confirm the necessity of enhancing customized subject selection satisfaction in consideration of various individual differences. In terms of the purpose of subject selection, autonomy and diversity of choice can be a way to guide and improve satisfaction in subject selection in consideration of individual differences among students. By analyzing the autonomy of intrinsic motivation, purpose, and diversity for subject selection, measures and implications for enhancing subject selection satisfaction were discussed.
Conceptual Validation Analysis of Ellis ' s Irrational Beliefs and Exploration of an Alternative Measurement Tool Framework

Published: January 2025

This study aimed to conduct a conceptual validation of Ellis's irrational beliefs, analyze the limitations of existing measurement tools, and propose a framework for a new measurement tool. First, an examination of the irrationality of 11 Ellis' irrational beliefs revealed that each belief violates "logical validity" by accepting propositions that cannot stand alone, "empirical verification" in that many incompatible facts actually occur, "flexibility" by keeping unidirectionality and rigidity, "practicality" by producing negative outcomes and "adaptive emotion" by triggering maladaptive emotions and behaviors. Additionally, a content analysis of three domestic irrational beliefs scales revealed several limitations: They fail to differentiate extreme responses for each item, do not conceptually focus on the relevant factor, reflect beliefs related to personal traits and situations rather than general objects, measure emotional and behavioral states instead of thoughts, and exhibit conceptual expressional overlapping. Finally, a framework for a new measurement tool was proposed to address these issues. This tool presents third-person scenarios including the core content of each Ellis's irrational belief and asks respondents to rate the similarity between their and the protagonist's thoughts. This self-reflective measurement framework is expected to reduce defensive responses commonly associated with self-report scales of irrational beliefs.

Authors: Perea Murillo Mirla , Mosquera Pino Jovanny
Published: January 2025

El artículo que se presenta a continuación nos lleva a explorar relaciones y vivencias a partir del conocimiento ancestral comunitario que se asocian con la mística en condiciones de producción, supervivencia y autoabastecimiento de los pueblos afro e indígenas asentados en territorios étnicos que desde épocas inmemoriales basan sus saberes en la exploración de la oferta natural y cultural, que se asocia a su vez con la cosmogonía. De esta manera, hablar de mística y lo desconocido asociado con los sistemas productivos y las dinámicas hombre-fauna-flora, despertará en el lector una visión e intuición de lo que pasa a su alrededor que no se explica, pero que sucede y es real porque se evidencia a través del comportamiento del ser humano, las plantas y los animales como las abejas nativas sin aguijón, seres vivos que representan la vida en todas sus expresiones, desde su estructura interna por su sociabilidad y cooperación, como también por las funciones que cumplen externamente a nivel ecosistémico y productivo.
