On relations between topological and algebraic structures of quasigroups
Authors: Ludkovsky S.V.
Published: December 2024

In this paper we study specific features of the relations between topological and algebraic structures of quasigroups and loops. We study the measurability of subsets of topological quasigroups and loops with respect to invariant measures. We study the family of non-measurable subsets in locally compact non-discrete loops. We find out the existence of locally $\mu$-zero subsets that are not $\mu$-zero in a locally compact left quasigroup that is not $\sigma$-compact. We study quotient spaces of measurable spaces on quasigroups. Moreover, we study homogeneous spaces of quasigroups and countable separability of subsets in them.

THE APPLICATION OF AFFECTIVE TAXONOMY IN CHARACTER DEVELOPMENT OF STUDENTS
Authors: Khumaimah Rina Rinatul
Published: December 2024

Affective taxonomy discusses the mastery of children's affective domains, which can be observed through moral aspects demonstrated by their feelings, values, motivation, and attitudes. The affective domain is crucial because it directly impacts the character formation and acculturation of children's behavior. The author explores this topic starting from practical aspects in education, particularly emphasizing the urgency of fostering politeness and respect in daily life. A child whose affective domain has been well-developed in both the family environment and school settings, particularly through effective teaching and learning processes, will exhibit positive attitudes in both academic activities and daily interactions outside of school. Consequently, students with a strong mastery of the affective domain will develop good social lives, admirable character, and the ability to handle critical situations wisely. This study is a literature review, primarily investigating the application of Bloom’s affective taxonomy in shaping students’ character. The data collection process involves a literature study method consisting of several stages: data collection, critique, interpretation, and writing. This research is expected to serve as a reference for shaping children’s character not only in school environments but also within families, using the stages outlined in the affective taxonomy.
THE ROLE OF ISLAMIC EDUCATION TEACHERS IN DEVELOPING STUDENTS' CREATIVITY AND INNOVATION IN LEARNING
Authors: Samsudin Samsudin
Published: December 2024

This study discusses the role of Islamic Education (PAI) teachers in developing students' creativity and innovation in learning. The current issue in education is the lack of encouragement from teachers to motivate students to innovate in the teaching and learning process, as well as the limited exploration and development of student creativity. This situation affects the quality of learning in schools, particularly in religious education, which should inspire students to think critically and creatively. This research uses a qualitative method with a descriptive approach. Data were collected through in-depth interviews with PAI teachers, classroom observations, and learning documentation. The focus of this research is to understand how PAI teachers can play a role in encouraging students to be more creative and innovative in their learning processes, as well as the strategies teachers implement to support the development of this potential. The findings indicate that PAI teachers play a significant role in fostering students' creativity and innovation. Teachers who utilize interactive teaching methods, such as group discussions, collaborative projects, and the use of technology, are more effective in stimulating students' interest in learning. Furthermore, PAI teachers who allow freedom of expression and encourage students to try new things in religious education can create a more dynamic and enjoyable learning environment. Thus, PAI teachers hold a key role in developing students who not only understand religious content but also apply it innovatively and creatively in their daily lives.

Authors: Adiasany Lawrenda , Chipunza Crispen , Dzansi Lineo , Adewumi Samson
Published: December 2024

Employee engagement has become a prominent topic in workplace discourse, particularly within academia, yet the academic literature on this subject remains relatively limited, especially in the context of Ghana. This paper seeks to address this gap by examining the factors contributing to employee engagement among academics and exploring their interrelationships for enhanced engagement of faculty. This was done through a comprehensive literature review, drawing on peer-reviewed journal articles, working papers, textbooks, and other relevant published sources, as well as online databases, including EBSCO Business Source Premier, Emerald Full Text, Google Scholar, Sci-Space, Science Direct, Sci-Hub, and Scopus. This study identifies key factors influencing employee engagement in higher education institutions as co-worker relationships, effective supervision, confidence in management, meaningful work roles, perceived organisational politics, organisational resources, effective leadership, and compensation and monetary benefits. The findings reveal a concerning trend of a higher number of disengaged or unengaged employees compared to those who are actively engaged. Furthermore, the consequences of employee engagement identified in the literature include job satisfaction, employee retention, and organisational citizenship behaviours, while challenges and barriers to engagement include poor management-union relationships, poor work environments, poor management practices, and inadequate communication. This paper contributes to the understanding of employee engagement in academia and provides insights for improving engagement levels in higher education institutions in Ghana.

Authors: Shandu Ruth Bhekekile , Nzimakwe Thokozani Ian , Utete Reward
Published: December 2024

Currently, South African government departments is inundated with common dire predicaments prominently manifested in the form of lack of punctuality, frequent leave requests, lack of engagement and poor management of employee wellbeing, resulting in high absenteeism rates. Flexible working schedules ameliorate the level of contentment and performance, which has been discovered to benefit both the employer and employee. There are limited previous studies done in the South African Public Sector on the subject of adopting flexibility conditions in the workplace. The empirical evidence on the subject is still sparse for the transitional economy like South Africa. Hence, this study sought to investigate the flexible work arrangements in the public organisation. The study adopted an exploratory design and a qualitative approach. A qualitative research approach was chosen for the study because it provided an opportunity to explore the research objectives in greater detail. The sample size and strategy used comprised organising focus group interviews as well as individual interviews, using a sample of 10 participants from different levels of the organisation. The findings of the study revealed that offering flexibility could help and support the emotional health of the employees. The study also found that a call for a flexible work strategy is of interest to most employees as it provides work-life balance. The organisation should consider implementing and making provision for flexible working arrangements which in turn improve job fulfilment, increase work and life, motivate employees, reduce absenteeism and increasing the quality of service delivery at all organisational levels.

Published: December 2024

This study was conducted to examine the effect of 3D printing cost, 3D printing technology adoption and regulatory compliance on environmental sustainability among 3D printing firms in South Africa. The study also investigated the mediating effect of regulatory compliance on the relationships between 3D printing cost and 3D printing technology adoption on environmental sustainability. The study adopted a deductive research approach, quantitative research method and an explanatory correlational research design. Simple random sampling technique was used to select a total of 152 employees of 3D printing firms in South Africa. Questionnaires served as the data collection instruments, and online data gathering was done using Google Forms. The Statistical Package for Social Sciences (SPSS) version 26 software was used for data coding, data entry, and descriptive statistics. Smart PLS 4 was used to conduct partial Least Squares (PLS) Structural Equation Modelling. Results of the study indicate that a significant negative relationship exists between 3D printing cost and environmental sustainability while a significant positive relationship was found to exist between 3D printing technology adoption and environmental sustainability among 3D printing firms in South Africa. A significant positive relationship also exists between 3D printing regulatory compliance and environmental sustainability. For mediation effects, it was found that 3D printing regulatory compliance negatively mediates the relationship between cost and environmental sustainability. The results also indicated that regulatory compliance does not mediate the relationship between 3D printing technology and environmental sustainability. The study concludes that, in as much as 3D printing costs and technology adoption are essential, regulatory compliance has significant role to play in ensuring the maximization of environmental sustainability in South Africa’s 3D printing industry.

Published: December 2024

Bullying is the aggression, violence, and threats that are targeted at the victims who are perceived to be weak. Learners living with disabilities are not immune to the phenomenon of bullying. Due to their vulnerability, they are targeted by bullies within the learning environment. Learners living with disabilities are targeted physically, emotionally, and through the use of technology. Learners fear reporting incidents of bullying because of the lack of action and consequences for the perpetrators of bullying. There is a huge increase in bullying incidents at schools against learners living with disabilities because of the inability to report the violence and harassment caused by the perpetrators to the victims of bullying. The learners living with disabilities are being taken advantage of by the perpetrators because of the fear of reporting violent behaviour to the teachers at school. The study applied the qualitative research method to explain the fears and inability to report bullying incidents by learners living with disabilities. Snowball sampling was used to select the study population within different schools, with a sample of about 11 learners considered. An exploratory research design was adopted in this study to explore the challenges experienced by the victims of bullying with regard to the fears of reporting bullying incidents. The study has adopted the interview as an instrument for collecting data. Thematic analysis was used to analyze the information collected from the learners living with disabilities. The study has observed the ethical considerations to ensure respect for the rights of the participants and universal observations for studies that involve human beings.

Authors: Vezi Phumelela Talent , Rajlal Ashnee , Chitamba Anos , Muchowe Regis
Published: December 2024

Globally, staff development is essential for enhancing employee performance and promoting organizational success (Akdere & Egan, 2020). In the context of local municipalities in KwaZulu-Natal (KZN), the absence of effective staff development has been recognized as a significant factor contributing to inadequate service delivery (Thusi & Selepe, 2023). Although the importance of staff development is acknowledged, municipalities face challenges in determining the effectiveness of these initiatives (Zulu, Yalezo & Mutambara, 2022). The COVID-19 pandemic has further intensified these issues, resulting in organizational changes, such as the shift to remote work, which have affected employee performance (Rogerson & Rogerson, 2020). This study investigates the influence of staff development programs on employee performance, with a focus on the Msunduzi Municipality. A literature review identified notable challenges, including insufficient engagement, inadequate compensation, and a lack of consultation during the development of performance management systems (Khunoethe, 2021; Govender & Bussin, 2020). The study is grounded in Human Capital Theory, which suggests that investing in employee skills leads to enhanced performance and improved service delivery (Mphahlele & Zandamela, 2021). The methodology involved purposive sampling and in-depth interviews with staff at the Msunduzi Municipality to gain insights into their perceptions of staff development programs. The findings indicated that while training programs were appreciated, they often lacked alignment with broader organizational goals. Personal Development Plans (PDPs) were identified as vital for synchronizing individual growth with municipal objectives; however, challenges related to performance management persisted, reflecting a compliance-driven culture. The study advocates for the implementation of a more integrated staff development framework that focuses on goal-oriented, needs-based training aligned with organizational objectives. Additionally, continuous monitoring and mentorship programs are recommended to ensure ongoing improvements in service delivery and employee performance. Addressing economic constraints through strategic resource allocation will be crucial in overcoming these challenges.

Authors: Gongbing Sun , Yuping Yuan
Published: December 2024

The distribution of soil nutrients in cultivated land was clarified and the soil fertility was systematically evaluated and analyzed. First, five important indicators that have a greater impact on soil comprehensive fertility were selected, and the index data were standardized. According to the different impacts of each indicator on soil fertility, the average value of partial correlation coefficient between each indicator and other indicators was calculated, and a certain weight was given to each indicator. The inverse absolute value method was used to construct a fuzzy similarity matrix, and the fuzzy similarity matrix was transformed into a fuzzy equivalent matrix to obtain dynamic clustering results. Finally, statistics were used to determine the optimal threshold value as 0.993 and the relative optimal soil classification number as 7 categories. The experimental results are in agreement with the actual situation, which proves the effectiveness of the fuzzy dynamic clustering algorithm.

Published: December 2024

Oral floor defects pose a significant challenge in reconstruction. The primary goal of reconstruction is to preserve tongue mobility, which allows for restoration of chewing, swallowing, and phonation. Current literature suggests that a nasolabial flap is a reliable treatment option for the reconstruction of this type of defect, with a low complication rate and excellent functional and aesthetic results. We present a patient who underwent resection of a gingivomandibular tumor. Due to his age, and the size of the defect, reconstruction was performed with a nasolabial flap. There were no postoperative complications. The purpose of this presentation is to demonstrate the use of the nasolabial flap for reconstruction of the floor of the mouth and to determine its advantages, disadvantages and interest compared to other surgical and microsurgical techniques.

A well-known problem in achieving an environmental effect from the use of natural gas is the loss of gas fuel during valve overlap, as well as during incomplete combustion at low consumption of the mixture when supplied to the intake manifold. An important condition affecting the amount of lost fuel is the method of supplying the gas-air mixture. It makes sense to imagine a description of a jet of gas fuel in an air flow in the geometry of the intake pipeline, as in the shape of the passage of the axis of the jet in the drifting flow. Knowing the depth of penetration into flow structures and its geometry makes it possible to position the jet in such a way as to avoid the accumulation of gas fuel in the intake manifold of a car engine. When describing the shapes of jet orientation, the empirical coefficient of penetration resistance is of great importance. An attempt was made to find a pattern of changes in the coefficient depending on the initial angle of fuel supply in the smaller direction of the jet advance.

Resumo Fundamento: A diabesidade é uma condição caracterizada pela coexistência de diabetes tipo 02 e obesidade. As causas são multifatoriais, resultantes de uma complexa interação de fatores genéticos e comportamentais. Entre os fatores comportamentais, destacam-se a inatividade física, os hábitos alimentares inadequados e o consumo excessivo de álcool e tabaco. Objetivo: Investigar o agrupamento (clustering) da inatividade física e outros fatores de risco e a associação entre as combinações de fatores de risco e a presença de diabesidade em adultos quilombolas. Métodos: Trata-se de estudo transversal com amostra composta por 332 adultos de meia idade e idosos (idade ≥ 50 anos), selecionados entre os participantes do estudo "Perfil epidemiológico dos quilombolas baianos". Os dados foram obtidos por meio de entrevistas e avaliação antropométrica. Para a análise dos dados, foram utilizadas estatísticas descritivas, análise de cluster e procedimentos de regressão logística multinominal. Resultado: A maior prevalência de agrupamento foi identificada para as combinações de consumo regular de álcool sem a presença dos demais fatores (O/E=14,2; IC95%= 0,87-1,15), seguido de consumo regular de álcool e tabaco (O/E=10,3; IC95%= 0,64-0,95) e consumo regular de álcool, tabaco e alimentos ricos em açúcar e gorduras (O/E=6,8; IC95%= 1,31-1,75). Na análise bruta, foram observadas associações entre inatividade física sem a presença dos demais fatores (OR= 0,82 IC95%= 0,78-0,86) e diabesidade. Conclusão: O consumo de álcool foi o fator mais prevalente nas maiores combinações avaliadas. Além disso, inatividade física, sem os outros comportamentos analisados, e a ausência de todos os comportamentos associaram-se à diabesidade apenas na análise bruta.

RESUMO Fundamento: Há carência de informações nacionais em relação a terapias utilizadas e evolução nos pacientes com síndrome coronária aguda com elevação de ST (SCACEST). Objetivos: Avaliar as terapias baseadas em evidência, a ocorrência de desfechos, uso de reperfusão e preditores para não receber reperfusão nos pacientes com SCACEST em um registro nacional multicêntrico. Métodos: Pacientes com SCACEST do Registro ACCEPT com até 12 horas de sintomas foram seguidos por 1 ano para ocorrência de eventos cardiovasculares maiores. Um p < 0,05 foi aplicado para todas análises. Resultados: Na análise de 1.553 pacientes, a taxa de reperfusão foi de 76,8%, variando de 47,5% na região Norte a até 80,5% na região Sudeste. A taxa de eventos cardiovasculares maiores foi de 12,5% em 1 ano. A prescrição de terapias baseadas em evidência na admissão hospitalar foi de 65,6%. A presença de hipertensão (odds ratio [OR] 1,47; intervalo de confiança [IC] 95% 1,11 a 1,96; p < 0,01), infarto agudo do miocárdio prévio (OR 1,81; IC 95% 1,32 a 2,48; p < 0,001) e as regiões Norte (OR 4,65; IC 95% 2,87 a 7,52; p < 0,001), Centro-Oeste (OR 4,02 IC 95% 1,26 a 12,7; p < 0,05) e Nordeste (OR 1,70; IC 95% 1,17 a 2,46; p < 0,01) foram preditores independentes de não utilização de terapia de reperfusão. Conclusões: No seguimento de 1 ano do Registro ACCEPT podemos verificar uma ampla variação dentre as regiões no que tange a aderência às melhores práticas de cuidado. Ser atendido nas regiões Norte, Centro-Oeste ou Nordeste, ter hipertensão arterial sistêmica ou infarto prévio foram preditores independentes de não utilização de terapia de reperfusão.
