Authors: Simbolon Frida Grace Greetje , Putu Prima Wulandari  
Published: October 2024

This study aims to examine the effect of managerial ownership, institutional ownership, and diversification on firm value—in which managerial ownership is represented by the number of shares owned by the manager divided by the total outstanding shares; institutional ownership is represented by the number of shares owned by the institution divided by the total outstanding shares; diversification is represented by Herfindahl Index; and firm value is represented by Price to Book Value. This study employs a quantitative approach and involves secondary data. The population includes all healthcare and technology companies listed on the Indonesia Stock Exchange between 2019 and 2022, from which the samples of 36 companies are selected through a purposive sampling method and analyzed by panel data regression utilizing Econometric Views (Eviews) 12 software. The results of the Chow and Hausman test indicate that the Fixed Effect Model (FEM) is the best regression model for this study, exhibiting that managerial ownership has a positive effect on firm value, and institutional ownership and diversification have no effect on firm value.

Bloque de baja conductividad térmica a partir de un concreto geopolimérico híbrido basado en cenizas volantes y otros residuos industriales
Authors: Martínez-Gutiérrez Fabio , Valencia-Saavedra William Gustavo , Mejía-de-Gutiérrez Ruby 
Published: October 2024

La utilización de cementantes alternativos y el aprovechamiento de residuos industriales, como materiales suplementarios o agregados en la producción de concretos y elementos estructurales que garanticen buenas prestaciones mecánicas, disminución de la carga muerta y un elevado confort térmico, están en concordancia con los principios de economía circular en el sector de la construcción. Por ello, el objetivo de esta investigación fue desarrollar un cemento híbrido basado en la activación alcalina con sulfato de sodio (NS) de una mezcla de ceniza volante (CV), humo de sílice (HS) y cemento portland de uso general (OPC, por sus siglas en inglés), en proporciones (CV+HS)/OPC del 70/30 %. La metodología empleada consistió en desarrollar el cementante hibrido, el cual fue clasificado como de moderado calor de hidratación (tipo MCH), y posteriormente utilizarlo, en proporciones de 500 kg/m3 y 600 kg/m3 para producir concretos estructurales incorporando en la mezcla agregados reciclados gruesos (AGR) y finos (AFR), obtenidos a partir de residuos de construcción y demolición (RCD). La mezcla 600 R a 28 días de curado alcanzó un valor de 18,9 MPa, y reporto un módulo de elasticidad de 27 GPa. Este concreto se validó en la producción de bloques perforados estructurales y, con el fin de mejorar el confort térmico de los concretos, se realizó sustitución del 10 % y 20 % en volumen de agregado fino reciclado por corcho reciclado. La introducción de corcho en la mezcla, aunque redujo la resistencia a compresión del bloque en un 29 %, permitió disminuir la conductividad térmica en un 32 %. Basado en los resultados obtenidos, se concluye que el uso de un 10 % en volumen de corcho como reemplazo del agregado fino en la mezcla de concreto híbrido permite obtener un bloque estructural con características de confort térmico. Las proporciones de la mezcla considerada óptima fueron de 52,5 CV+17,5 HS+30 OPC, 4 % NS, 70 % AGR, 20 % AFR, y 10 % corcho.
The Role of Artificial Intelligence in Higher Education
Authors: O Donnell Frances , Porter Mark , Fitzgerald Dr Stephen 
Published: October 2024

The integration of Artificial Intelligence (AI) in higher education has sparked a transformative shift in pedagogical methodologies, student engagement, and academic integrity across the UK and Ireland (Dogru, et.al, 2023). This qualitative study delves into the multifaceted implications of utilising AI in academic assignments from the perspective of higher education students, drawing on semi-structured interviews carried out with higher education students. The findings reveal a variety of perceived benefits, including enhanced study efficiency, personalised learning support (Hanaba et al., 2020; Yang, 2021), and the potential of AI to level the academic playing field for students with diverse needs. However, these advantages are in contrast with students’ perceptions of a wide range of significant concerns and challenges, notably the ethical dilemmas surrounding academic honesty, the potential for student dependency on AI leading to diminished knowledge and skill development, as well as the issue of equity in relation to students’ access to AI resources. Moreover, the study stresses a critical gap in institutional guidance regarding AI use, with students voicing a need for clear, consistent guidance from universities. This paper highlights the complex landscape of AI in academia, advocating for a balanced approach that harnesses AI's potential while addressing ethical, educational, and equity challenges. The study emphasises a need for immediate and more in-depth research into the use of AI in higher education from the perspective of both students and university staff in Ireland/UK.

Published: October 2024

Abstract

OBJECTIVE
Determine the prevalence, types, and geographical distribution of oral tumors in dogs in Switzerland to provide insights into demographics, tumor characteristics, and trends.

METHODS
The medical and pathology records of dogs diagnosed with oral tumors from 2012 to 2022 were sourced from diagnostic laboratories in Switzerland. The focus was on histopathologically confirmed oral neoplasms. Inflammatory, viral, and cystic lesions were excluded. Geographic trends were analyzed by use of postal addresses, revealing local distributions.

RESULTS
Of the 948 reports, 773 cases fulfilled the study’s criteria. Benign tumors constituted 63% (487 of 773), with peripheral odontogenic fibroma being the most common (77.8% [379 of 487]). Among the malignant tumors, malignant melanoma was the most frequent (38.1% [109 of 286]), followed by squamous cell carcinoma (21% [60 of 286]) and fibrosarcoma (8% [23 of 286]). The locations of tumors varied, with a higher prevalence of malignant melanoma on the lips. Histopathologic findings indicated ulceration and necrosis were more common in malignant tumors. Significant differences were noted in the mitotic index between benign and malignant groups. No tumor predisposition was noted for any breed. Oral tumors were prevalent in older dogs (median age, 9.4 years).

CONCLUSIONS
The findings highlighted the predominance of benign tumors in dogs in Switzerland, with specific histopathologic features distinguishing benign from malignant cases.

CLINICAL RELEVANCE
Understanding the prevalence, types, and geographic distribution of oral tumors based on the representation in dogs in Switzerland may aid in early detection, appropriate diagnostic workup, and informed treatment planning for oral tumors in dogs.

Published: October 2024

Abstract
Screening tests are now readily accessible, quick and highly sensitive. Diagnostics of HIV infections involves serological testing followed by confirmation tests by molecular biology methods (NAAT). Fast, accurate, anonymous and free HIV testing has been provided by Voluntary Counselling and Testing Points (VCTs) for over 20 years to any adult in Poland, regardless of nationality. Additionally, the educational activities are conducted aimed at informing people from various social backgrounds about HIV prevention and diagnostic possibilities, as well as other sexually transmitted infections (STIs). The aim of the article was to present the procedures for the operation of VCTs in Poland, their location, testing scheme and a summary of the activities that promote such points in the medical community. Between 2019 and 2023, 157,833 people registered for HIV testing in VCTs in Poland, of which 10,177 (6.45%) were foreigners. In the analyzed period, the number of tests among foreigners visiting VCTs in Poland almost doubled, from 1,552 in 2019 to 2,827 in 2023. In addition, a higher percentage of positive results was recorded among foreigners – 5.08% compared to Poles – 1.24%. The frequency analysis of positive results detection reported in VCTs vs. National Institute of Public Health NIH – National Research Institute showed that, on average 26% (2,342/8,891) of positive results in Poland from 2019–2023 were detected in the framework of tests carried out in VCTs. The operation of VCT points in Poland enables the reaching of a larger group of people, especially key adult populations. It is a valuable complement to routine diagnostics outside the health care system.
Zoonotic Diseases in Northen Cyprus: Current and Future Threats
Authors: Güvenir Meryem , Arikan Ayşe 
Published: October 2024

Abstract
Diseases transmitted naturally between animals and humans are referred to as zoonoses. Zoonotic diseases are responsible for many pathogenic infections in humans, especially in endemic regions. In recent years, emerging and re-emerging zoonotic infections have become widespread and pose a threat worldwide. Transmitted such bacterial, viral and parasitic infections have been detected in Northen Cyprus over the years. Climate change and human migration are increasing essentially, making such infections potentially more dangerous. To quickly detect these pathogens and limit their spread, it is crucial for the island to control their animal reservoirs. In addition, continued and expanded research is essential for global surveillance.
This review aimed to provide an overview of the etiology of the most recorded zoonotic diseases in Northen Cyprus, their impact on human health, and measures to control their spread better.
Klebsiella Pneumoniae – Taxonomy, Occurrence, Identification, Virulence Factors and Pathogenicity
Authors: Ochońska Dorota , Brzychczy-Włoch Monika 
Published: October 2024

Abstract
Gram-negative bacilli Klebsiella pneumoniae are among the most important pathogens responsible for healthcare-associated infections (HAIs). These bacteria often have high pathogenic and epidemic potential, contributing to infection outbreaks worldwide. K. pneumoniae is part of the natural microbiota of humans. At the same time, as an opportunistic microorganism, when the host organism is weakened, it can cause serious infections such as pneumonia, urinary tract infections, septic infections and intra-organ abscesses. Widespread distribution in nature and exceptional adaptability provide K. pneumoniae with the opportunity to master new niches in the hospital environment, which poses a threat to hospitalized patients. Also, the bacteria are increasingly causing life-threatening infections in the non-hospital environment. The pathogenicity of K. pneumoniae is determined by the presence of many virulence factors such as capsular polysaccharide (CPS, K antigen), lipopolysaccharid (LPS, O antigen), fimbrial and non-fimbrial adhesins, siderophores (aero-bactin, enterobactin, salmochelin and yersiniabactin), heat-stabile and heat-labile enterotoxins, cytotoxins and biofilm-forming ability. Currently, hypervirulent strains of K. pneumoniae (hvKp) equipped with new virulence traits constitute a significant danger. The paper presents these bacteria concerning the global threat arising from the dynamic spread of hvKp strains in hospitals in Poland and worldwide.
APPLICATION OF PROBLEM-BASED LEARNING MODEL (PBL) IN PJOK LESSONS TO IMPROVE CRITICAL THINKING SKILLS IN THE ERA OF DIGITALIZATION
Authors: Is Zulheri , Subhananto Aprian , SAIFI Syahrianur 
Published: October 2024

The low critical thinking of students while learning can be seen from several aspects such as the inability of students to identify a problem properly, so that the solution in learning is not resolved properly. The purpose of this study is to see the improvement of critical thinking skills through a problem-based learning model in Physical Education, Sports and Health (PJOK) learning. The research design used in this study is Quasi Experimental Design, which is a development of True Experimental Design. This research was carried out at MTsN Model Banda Aceh with the research subjects of Class VIII-1 students totaling 32 students with purposive sampling sample collection techniques. The instrument used in terms of seeing students' critical thinking skills uses a written test with true-false question types. The results of this study show that the problem base learning model is able to improve students' critical thinking skills well in physical education learning. It can be seen in the descriptive statistics of the average value of the problem base learning model of 0.91, while in conventional learning of 0.86, it means that the problem base learning model is better than conventional learning in terms of improving students' critical thinking skills in physical education. Keywords: Problem Base Learning, Critical Thinking, PJOK lessons
Burden of hepatitis B in asymptomatic blood donor population of India: A systematic review & meta-analysis
Authors: Shrivastava Manisha , Agrawal Amit , Das Saikat , Mishra Shweta 
Published: October 2024

Background & objectives
India has been classified as an intermediate Hepatitis B Virus (HBV) endemic country, and the transmission is believed to mostly occur horizontally. However, community-based data on HBV prevalence among blood donors in India are limited. The burden of Hepatitis B Virus (HBV) is unknown in the asymptomatic blood donor population. We therefore conducted a meta-analysis to assess the prevalence of the HBV among the blood donor population in India.

Methods
We searched different databases for research articles on the prevalence of HBV in the blood donor population from India. Following the PRISMA guidelines, forty articles published between January 2013 and October 20, 2023, were selected for meta-analysis after removing duplicates and conducting a two-level screening process. Review Manager Version 5.3 (Rev Man 5.4) was used for statistical meta-analysis. The study has been registered with PROSPERO (number CRD42023487616).

Results
Forty articles were selected out of the 527 published manuscripts for meta-analysis, and a total of 22,22,736 blood donations were studied. Of these, 24,151 individuals (1.11%) were identified either as chronically infected with HBV or living with HBV infection. A pooled prevalence of approximately 1.11 per cent with a 95% confidence interval (CI) of (0.011; 0.0112) (common effect model) or 95% CI of (0.0079; 0.0116) (random effects model) was estimated. The included studies exhibited a high level of heterogeneity, probably due to different diagnostic approaches followed in different studies.

Interpretation & conclusions
The burden of hepatitis is profound, impacting public health, economies, and societies in India. The outcome of this study would help address such a burden and develop comprehensive strategies focused on prevention, early diagnosis, treatment, and necessary collaboration to achieve significant reductions in hepatitis-related morbidity and mortality.
