Fast algorithms for edge coloring in clustered hypergraphs: A study of computational efficiency
Authors: Jawad Wasan Mustafa
Published: January 2025

The generalization of edge coloring in hypergraphs, especially clustered ones, remains an open problem due to the intricate structure and organization of hyper-edges grouped in clusters. This study addresses the computational challenges associated with edge coloring in clustered hypergraphs by introducing a novel suite of fast algorithms specifically designed to achieve improved accuracy and computation time. The algorithms utilize structural properties such as hypergraph Laplacian spectral features and submodular optimization to enhance efficiency. Experimental results demonstrate a 10-15% improvement in clustering accuracy and a 20% reduction in computational time compared to baseline methods, validating the approach for both synthetic and real-world datasets. These findings contribute to hypergraph theory and propose a practical solution for applications in network layout, parallel computing frameworks, and data organization. Future work could further optimize these algorithms for large-scale real-time applications.

Published: January 2025

Good sleep quality in congestive heart failure (CHF) patients helps repair heart muscle cells. Sleep hygiene is one of the non-pharmacological interventions to overcome sleep disorders. This study aims to determine the effectiveness of sleep hygiene on sleep quality in CHF patients. A Randomized Controlled Trial (RCT) with two groups was taken using probability sampling with block random sampling method. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) and sleep habits using the Sleep Hygiene Index (SHI). Outputs were measured based on the change in the mean between the measurement time using the paired t-test and the difference in the mean between groups using the independent t-test.  A total of 30 respondents were involved in this study. The intervention group showed a significant improvement in sleep quality after sleep hygiene therapy with a mean difference (MD) of 4.20 (SE=0.70; p-value=<0.01). Sleep quality between the two groups showed a significantly greater difference in the intervention group than in the control group (MD=-2.13, SE=1.00, p-value=0.04, effect size (Cohens'd)=-0.77). Sleep hygiene is a non-pharmacological intervention that effectively improves sleep quality in patients with CHF.

Authors: Kumar Jitender , Kumar Kem Anil
Published: January 2025

Background: Acute myocardial infarction (AMI) is a leading cause of morbidity and mortality worldwide, often complicated by congestive heart failure (CHF). This study aims to explore the hospital outcomes of patients with AMI complicated by CHF, focusing on demographic factors, comorbidities, and treatment strategies.
Method: Conducted over one year at the Saraswathi Institute of Medical Sciences, this study enrolled 157 patients diagnosed with AMI and CHF. Data collection included clinical assessments and laboratory investigations, with primary outcomes measuring hospital length of stay, in-hospital mortality, and readmission rates. Statistical analyses were performed to identify significant associations.
Result: The average length of hospital stay was 10.5 ± 3.2 days, with an in-hospital mortality rate of 12.1%. Hypertension was significantly associated with mortality (p = 0.020), while the odds ratios indicated that patients with diabetes and chronic kidney disease had increased mortality risks. Notably, longer hospital stays correlated with in-hospital mortality and readmissions (p < 0.001).
Conclusion: CHF significantly impacts hospital outcomes in AMI patients, with hypertension as a key factor for increased mortality. Targeted interventions for at-risk populations may improve patient care and outcomes.
»V imenu narodov Jugoslavije!« Procesi pred vojaškimi sodišči poleti 1945
Authors: Čoh Kladnik Mateja
Published: January 2025

In the aftermath of the Second World War, in May 1945, the first court-martial proceedings started in Slovenia; the convicted were mostly civilians, with very few military personnel among them. The courts were organized, heard cases, and imposed sentences based on the Court-Martial Regulation of May 1944. Proceedings were swift and brief. Most of those convicted in courts-martial were civilians accused of having collaborated with the occupying forces and having acted against the Partisan movement during the war, (supposedly) having been members of the occupying forces’ political organizations and military formations; proceedings due to membership in the Kulturbund were particularly numerous. There were also judicial proceedings against German and Slovenian entrepreneurs, owners of financial institutions,and military personnel – members of the Slovenian Home Guard, who were tried in the camps of Šentvid and Teharje.

Teaching approach to free-form surfaces and milling tool paths aimed at demonstrating CAD/CAM integration based on open-source software
Authors: Halla II Ricardo , Fernandes Fernando Henrique , Silva Lenine Marques de Castro , Andrade Igor Lopes de , Oliveira Adilson José de
Published: January 2025

The widely used approach to teaching computer-aided design (CAD) and manufacturing (CAM) integration in undergraduate courses, based mainly on the offer of didactic-textual materials and classroom activities, has not been well received by engineering students. The main reasons are that the method is dependent on specific resources in the software, which promotes highly time‐consuming operations, and the algorithms and operations that run in background are invisible to the students. The objective of this study was to use open-source software to demonstrate how the CAD/CAM software programs are integrated, based on parametric curves and surfaces, linear transformations, offset surfaces and transparent algorithms. To achieve this goal, a free-form surface was created and strategies to generate milling tool paths were investigated, to help undergraduate engineering students understand how the proprietary solution works inside commercial software programs. Real-time visual results were obtained with GeoGebra® and the students were encouraged to apply knowledge from previous basic engineering courses, which allows an intuitive insight. This increases interest in the engineering fields and enhances the development of the student’s professional skills. A proposed approach is the combination of theoretical and practical issues, allowing distance learning and the use of technology-based tools in classroom teaching.

Os fenômenos cardioembólicos em idosos com aterosclerose representam um desafio crescente, considerando a alta prevalência de comorbidades e o impacto significativo na qualidade de vida. Este estudo tem como objetivo revisar sistematicamente a literatura, analisando os principais fatores de risco, mecanismos fisiopatológicos, abordagens diagnósticas e terapêuticas, além das complicações associadas. A aterosclerose é destacada como a base fisiopatológica que predispõe à formação de êmbolos, potencializando eventos graves, como o acidente vascular cerebral isquêmico. A coexistência de fibrilação atrial, comumente encontrada em idosos, agrava o risco de embolização e exige manejo terapêutico cuidadoso, incluindo anticoagulação e controle de comorbidades. Métodos diagnósticos avançados, como biomarcadores inflamatórios e técnicas de imagem, têm ampliado a precisão na identificação de pacientes em risco. O tratamento inclui intervenções farmacológicas, como estatinas e anticoagulantes, e estratégias não farmacológicas, como reabilitação cardiovascular. Apesar dos avanços, barreiras socioeconômicas e lacunas no conhecimento ainda limitam o manejo ideal dessa condição. Conclui-se que abordagens multidisciplinares e personalizadas são essenciais para reduzir a morbimortalidade e promover o envelhecimento saudável. Este trabalho ressalta a importância de políticas públicas que ampliem o acesso aos cuidados e investimentos em pesquisas futuras.
O CASO AMERICANAS: A RESPONSABILIDADE CIVIL NA RECUPERAÇÃO JUDICIAL DE SOCIEDADES ANÔNIMAS
Authors: Araújo João de Deus Lopes Oliveira de , Santos Vivian de Albuquerque Ramos , Fernandes Heliane Sousa
Published: January 2025

No segundo semestre de 2022, repercutiu nas mídias o escândalo de uma das maiores redes varejistas do Brasil, as Lojas Americanas. Nesse sentido, esta pesquisa objetiva demonstrar como os culpados pela atual crise da sociedade anônima (S/A) serão civilmente responsabilizados pelos prejuízos e danos. Assim, destaca-se que este estudo possui caráter explicativo, informativo e bibliográfico, pois analisa e expõe o escândalo financeiro da Americana à luz da Lei das Sociedades Anônimas (LSA), Lei de Recuperação Judicial e Falências (LRF), livros e artigos científicos. Ademais, conforme o Código Civil de 2002 (CC), ressalta-se que o desfecho mais coerente é a responsabilização da empresa pelas obrigações contraídas por administradores e conselheiros no exercício regular dos poderes representativos, salvo se violados lei ou estatuto social, hipótese do art. 158, II, da LSA. Ainda, a sociedade responderia pelos atos ilícitos praticados por auxiliares no exercício de suas funções, reservado, porém, o direito regressivo da empresa contra o preposto. De resto, responderá solidariamente o acionista controlador que ultrapassar os limites do seu poder de controle. Nesse viés, mostra-se pertinente para o empresariado e o sistema econômico-financeiro brasileiro o estudo sobre o caso, em vista do pedido de recuperação de grandes sociedades. Portanto, busca-se elucidar a responsabilidade civil em S/A’s e o processo de recuperação judicial da Americanas com foco na LSA e na LRF.

Consumer Education and Loyalty: Concepts, Approaches and Correlations
Authors: Remesovschi Natalia
Published: January 2025

In an era of change, consumer loyalty is essential for the success and sustainability of companies, and the challenge in these conditions lies in increasing or regaining customer trust. Consumers have access to a multitude of options and are increasingly demanding, making loyalty no longer a simple process. Thus, the effectiveness of relationship marketing campaigns largely depends on customers’ motivation to actively engage in their relationship with the company, being the result of a well-managed process of communication and creation of a valuable experience for consumers. An essential aspect of this process is consumer education. By educating consumers, companies can create a deeper connection with their customers, providing relevant, accessible, and personalized information. This approach contributes to the development of trust, a determining factor for loyalty. In the long run, fostering loyalty through education brings mutual benefits. Customers who feel informed and supported are more likely to remain loyal to a brand and recommend its products, contributing to the company’s long-term success. Thus, building a consumer education process becomes a strategic investment for any company looking to expand its base of loyal customers in a competitive environment.

Antimicrobial resistance (ABr) is a significant global health concern, exacerbated by the inappropriate use of antibiotics. This study aimed to assess the knowledge, attitudes, and practices (KAP) regarding antibiotic use and ABr among the population in the central and the western region of Saudi Arabia.A cross-sectional study was conducted using both face to face interview and an online questionnaire distributed via social media platforms. The questionnaire consisted of four sections: the first gathered sociodemographic characteristics of the participants; the second assessed knowledge of antibiotic use and ABr, while the third and fourth evaluated attitudes and practices related to antibiotics and ABr.Out of 486 participants, 333 (68.5%) were female, and 324 (66.7%) held a college degree. Overall, 186 (38.3%) of respondents demonstrated poor knowledge of antibiotics and ABr. Additionally, 256 (52.7%) reported inadequate attitudes towards antibiotic use. Furthermore, 275 (56.6%) exhibited poor practices concerning antibiotic usage. Factors influencing knowledge levels included gender, age, educational attainment, and occupational status, with those with bachelor’s degree showing greater knowledge of antibiotics and ABr compared to individuals in other occupations.Our study identified a concerning suboptimal level of knowledge, unfavorable attitudes, and inadequate practices regarding antibiotics and ABr among participants. To address this issue, educational health campaigns aimed at raising public awareness and promoting responsible practices are essential. Emphasizing the role of healthcare providers in education and enforcing stringent regulations on the non-prescription dispensing of antibiotics will also be crucial. Future research in this area is recommended to further explore these issues.
Understanding multidrug resistance in Staphylococcus aureus: The role of efflux pumps and key protein structures
Authors: Abuzar Mohammad , Fakki Foorkan
Published: January 2025

A rising health concern is the occurrence of illnesses brought on by multidrug-resistant bacteria in healthcare facilities or in public spaces. The growth of microbial biofilms and efflux pumps are the main causes of S. aureus'santibiotic resistance. Multidrug EPs cells utilizing proteins to detoxify from toxic substances, appear to be essential in the development of this drug-resistant bacteria. Through the extrusion of numerous unrelated chemicals, experimental data have demonstrated their role in reduced antibacterial resistance in bacteria as well as the possible significance in the emergence of resistant phenotypes. Efflux systems plays an important role in MDR resistance in addition to helping to transport molecules that are important for cell signaling, and because they are common, there is a real danger that we could soon return to a time before antibiotics. According to recent research, cells may use the efflux systems as the initial step of defence to prevent drugs from reaching deadly concentrations while waiting for a stable, more effective modification to occur. The primary facilitator superfamily-belonging S. aureusefflux pump NorAimparts resistance to various substrates. Even though many EPI i.e inhibitors of the efflux pump have been found, from them, no one has received clinical approval because of unfavourabletoxicity. In this review article,we will discuss the current understanding of the MDR efflux pump and its clinical importance, concentrating on current discoveries on the efflux system of S. aureus, and the regulation of efflux pump based on protein/gene expression, and emphasize significant genes and proteins along with their PDB IDs.

Authors:   Le Quy Don Technical University, Nguyen Manh Thuong
Published: January 2025

In some emergency traffic situations such as rescue, natural disasters... it is necessary to build a temporary bridge to cross the river. Using a quick-assembled floating bridge made of plastic buoys is the appropriate solution. This article presents the study of calculating the draft of continuous floating bridge assembled from plastic buoys. The author calculates the draft by two different methods, which are theoretical calculation and finite element modeling using SAP2000 software, to verify the discrepancy of the results of these two methods. The results obtained show that the discrepancy between these two methods is insignificant, and continuous floating bridge assembled with a layer of plastic buoys can withstand a small truck load of up to 12.3 tons.
AN APPROACH TO DETERMINE AND PREDICT THE MEAN PARTICLE SIZE OF A MUCK PILE AFTER BLASTING ACCORDING TO SWEBREC PARTICLE SIZE DISTRIBUTION LAW BASED ON THE FORM OF SINGLE SPHERICAL CHARGE IN LABORATORY SCALE
Authors:   Le Quy Don Technical University, Vu Tung Lam
Published: January 2025

In the manufacturing procedure at open-pit mines, tunnel construction or channel excavation activities, crushing rocks to a suitable grain size is one of the first technological steps, directly affecting the efficiency of the following steps in the overall process of drilling - blasting - loading - transporting. Currently, drilling-blasting is still an effective method in this field. However, controlling the blasting parameters to obtain a suitable mean particle size is still difficult for mining engineers and scientists. Hence, on a laboratory scale, this research carries out 6 blasting experiments based on the form of single spherical charge with a variety of powder factors but the same specimen condition, equations determining directly the Swebrec particle size distributions (PSDs) law are then established with the input data taken from sieve analysis, as a basis for establishing relationships among each pair of parameters such as the exponential coefficient of Swebrec PSD function b, the mean particle size Dtb, and the powder factor q. The results show that the obtained PSDs almost completely fit experiment data, coefficients of determination R2 for the entire data set are greater than 0.99. Each pair of relationships among b, Dtb, and q have R2 values greater than 0.98 with the addition of predictive significance. The calculations are modularized in Python programming language for use as a package. Compared to other existing methods, the final results can help quickly evaluate the quality of an explosion, appropriately calibrating explosion parameters to obtain the desired rock fragmentation without requiring knowledge of machine learning and statistics.

Authors:   Le Quy Don Technical University, Nguyen Thanh Sang
Published: January 2025

Construction projects on geological grounds, particularly coral reefs, hold significant importance for national security, defense, and marine economic development. However, the application of new technologies and enhanced pile foundation structures in these projects has been limited. This study focuses on researching and evaluating the correlation between the load capacity of traditional steel pipe piles, which are supplemented with two helical plates, and the variations in the distance of these helical plates along the depth of the pile in coral gravelly-sand using Mohr-Coulomb model by finite element method. The results of this study conclude that the load-bearing capacity of piles with two helical plates is 2.1 to 3.3 times higher than that of traditional plain round piles. In addition, a calculation function for the load-bearing capacity of the improved steel single-pipe pile in relation to the appropriate distance for the helical plates is proposed. This function is essential for projects built under the geological conditions of coral and the typical hydrological properties found in the offshore seas and islands of Vietnam.

Published: January 2025

The dynamic response of a concrete pavement system with load transfer dowels under the effects of moving loads is a topic of interest to many scholars. However, to fully understand the nature of the stress-strain state of the concrete slab, load transfer dowels, and the subgrade in the pavement structure, further research is needed. Using numerical methods with the commercial software ABAQUS 2020, this paper thoroughly investigates the dynamic behavior of rigid pavement structures under moving loads at a constant speed. The research results will provide road and airport engineers with valuable insights into the actual working conditions of rigid pavement structures.

Published: January 2025

This study focuses on determining bathymetric changes around offshore islands of Vietnam using remote sensing data available on the Google Earth Engine (GEE) cloud platform. Sentinel-2 multispectral satellite imagery was collected over three time periods, January 14, 2020, June 5, 2020 and June 15, 2021, coinciding with the wind season to analyze and calculate bathymetric changes. The results of the bathymetry compared to the field measurement points have coefficients of determination (R2) ranging from 0.83 to 0.94. The RMSE (Relative Mean Square Error) results obtained were 0.066 m, 0.048 m and 0.079 m, initially providing a map of seasonal bathymetry changes consistent with reality. This method demonstrates the efficiency and automation potential for tracking depth changes in the Vietnamese coastal region, especially around offshore islands. Moreover, it highlights the importance of continuous monitoring for environmental protection, navigation, and resource management.

El objetivo de la investigación es proponer una metodología para evaluar la eficiencia en la Gestión del Talento Humano (GTH) a través de la identificación de competencias laborales (ICC) en una empresa importadora. Aborda un enfoque teórico cuantitativo y metodológicamente a través de un instrumento validado por expertos que correlacionan la GTH como variable dependiente y la ICC como variable independiente. La originalidad radica en el desarrollo de un instrumento adaptable para evaluar estas variables. Los resultados muestran que el departamento al que pertenece un empleado tiene un impacto significativo en su desempeño, adicionalmente que algunas dimensiones de las variables predictoras tienen un impacto inverso, como lo es las competencias distintivas, que tienden a reducir los resultados en las estrategias y acciones para la GTH y la promoción de una interacción efectiva en los RRHH, mientras que las competencias funcionales las incrementa. Así mismo el nivel de responsabilidad muestra relación inversa con las competencias genéricas. El modelo muestra un ajuste adecuado, aunque hay margen para la inclusión de otras variables que puedan mejorar la capacidad predictiva y explicativa. El análisis estadístico sugiere que la estructura departamental y las competencias funcionales son determinantes en el rendimiento empresarial, mientras que las competencias distintivas y la responsabilidad juegan un rol, pero de manera inversa en algunos casos. En conclusión, la metodología propuesta se muestra prometedora al amparo de la aportación de conocimiento basado en análisis métrico, proporcionando una base sólida para futuras investigaciones en el ámbito académico y posibles intervenciones para el sector empresarial.

El presente estudio tuvo como objetivo principal, determinar la relación entre la violencia sufrida por la pareja y la motivación para seguir estudios superiores en estudiantes de una Universidad Pública de Yurimaguas – Perú. Se tuvo en cuenta como población a 1200 estudiantes universitarios de ambos sexos y de todas las carreras, los cuales fueron seleccionados mediante muestreo aleatorio simple concretando al final 291 participantes. La metodología empleada fue de tipo básica, con diseño no experimental, de corte transversal y nivel descriptivo correlacional. Se encontró que existe relación significativa negativa y moderada entre las variables de estudio (r=-0.462; sig>0.05), de igual forma con las dimensiones de la violencia de pareja (menos económica) con la motivación para seguir estudios superiores, además prevalece a nivel muy alto la violencia de pareja y bajo la motivación para seguir estudios superiores, por tanto, cuanto mayor sea el grado de violencia de pareja percibido, menor será el grado de motivación para seguir estudios superiores. Este hallazgo favorece a reconocer un problema que puede presentarse en los estudiantes universitarios y que las entidades pueden abordar en beneficio de estos.

Authors: Bruce Carlos V.
Published: January 2025

Se examina la dependencia de las Tecnologías de Información (TI) y cómo ha impulsado la necesidad de realizar auditorías de sistemas de información, que es un mecanismo para evaluar y garantizar la seguridad, eficiencia y el cumplimiento normativo. El estudio se centra en responder a la pregunta de investigación: ¿cómo contribuye la auditoría de sistemas de información al fortalecimiento de la gobernanza de la información y mitigación de riesgos en las organizaciones? Con este fin, el objetivo se centró en revisar los procesos de la auditoría en la mejora de los controles internos, la protección de los activos digitales y la generación de valor estratégico para las organizaciones. La metodología se basó en un estudio no experimental, descriptivo, documental y transversal, con un enfoque inductivo. Se analizaron 24 fuentes académicas y profesionales entre 2000 y 2024, centrándose en las áreas de auditoría de sistemas, ciberseguridad y gobernanza corporativa, presentando la información mediante tablas y figuras para facilitar la interpretación de los resultados. Se estableció que la auditoría de sistemas fortalece los controles internos al identificar vulnerabilidades y promover medidas correctivas, y que la protección de activos digitales se logra mediante estrategias como la segmentación de redes, los sistemas de detección de intrusos y la autenticación multifactor. Se destaca en las conclusiones que la incorporación de tecnologías avanzadas y la capacitación continua de los auditores son necesarias para aumentar su efectividad, así como mejorar la transparencia, la rendición de cuentas y la gestión de riesgos.

This study explored the strategies employed by School Governing Bodies (SGBs) to enhance the quality of education in three selected secondary schools in the Eastern Cape Province, South Africa. Despite some improvement in Grade 12 results within the province, a downward trend was observed until 2016, raising concerns given that SGBs are legally mandated to improve educational quality. This qualitative research employed semi-structured interviews to gather data from twenty-two participants, including eighteen SGB members, two school principals, and two Education Development Officers (EDOs). The study applied Governance Theory as a framework to investigate the strategies used by SGBs to promote educational quality in their schools. The findings revealed that while SGB members were often inadequately trained for their governance roles, some employed strategies such as goal-sharing, fostering a common purpose, and engaging the community to improve education. However, the study also highlighted divergent views, with some participants questioning whether SGBs had any concrete strategies to enhance educational quality. Based on these findings, the study recommends the development of clear guidelines to assist SGBs in formulating effective strategies to improve the quality of education in schools. This paper will contribute to the body of existing knowledge, practice, and policy development to enhance the performance of the SGB to enhance the quality of education in South Africa.

Background: In Bangladesh, the percentage of children found moderately and severely underweight were respectively 16.4% and 3.6% all over the country in 2018. This study aimed to determine the prevalence of and factors affecting childhood underweight<5 years old and identify socioeconomic inequalities contributing to childhood underweight in Bangladesh. Methods: Bangladesh Demographic Health Survey Data (2007, 2011, 2014 & 2017-2018) of 30,940 pairs were used for analysis. Chi-square tests were used to estimate the relationship between the independent variables chosen and underweight, binary logistic regression analysis was used to investigate potential risk factors, and decomposition analysis was conducted to assess inequality. Results: Binary logistic regression demonstrated that the children’s age, mother’s BMI, mother’s education level, father’s educational status, child delivery procedure, birth order of the child, recent diarrhea affectedness before the survey, sanitation, and wealth index were discovered to be essential variables affecting childhood underweight of children under 5 years old in Bangladesh.  Conclusion: The associated factors with underweight in this study should be considered when designing policies and programs, making it more effective to eradicate the underweight problem among children in Bangladesh.
