The study explored effective management strategies for improving early childhood education in Nigeria. Two research questions were raised in the study. The descriptive survey design was used. The study population was made up of 1,350 public Nursery School heads and 5,000 teachers in Delta State. A total number of 274 respondents consisting of 27school heads and 247 teachers were selected from 27 Nursery schools attached to public Primary Schools in Delta State. In selecting Public Nursery schools, proportional stratified sampling technique was used. 27 schools were selected from 9 Local Government Areas across the 3 Senatorial Districts in Delta State. Three Local Government Areas (LGAs) were randomly selected from each senatorial district given a total of Nine LGAs across the state. A self – designed questionniare titled “Management Strategies for Improving Early Childhood EducationQuestionnaire (MSFIECEQ)”, was validated and its reliability was equally determined through a pilot study using test re-test reliability technique with a coefficient index of 0.83. Each item was anchored on a Likert four rating scale of: Strongly Agree (SA), Agreed (A), Disagree (D) and Strongly Disagree (SD). The research questions raised were answered using simple percentage, mean score and standard deviation .From the findings, it was concluded that management strategies for improving early childhood education in Nigeria requires a multifaceted approach. The Nigerian government, private sector and international organizations must collaborate to address funding challenges, improve resources utilization and ensure equitable access. Based on the conclusion, it was therefore recommended that government and policy-makers should increase government allocation for early childhood education, encourage private sector investment through tax incentives and corporate social responsibility, encourage inspection and supervision of early childhood education centers, review the curriculum, foster community engagement and parental involvement.

Disease perception, treatment-seeking behaviour and psychosocial impact of acne vulgaris among university students – A cross-sectional study
Authors: Tan Yi Jun , Jamil Adawiyah , Preamala Gunabalasingam
Published: February 2025

Introduction: Acne is a common chronic inflammatory disease. Misconceptions hinder effective management. This study aimed to explore disease perception, treatment-seeking behaviour and the psychosocial impact of acne.
Methods: A cross-sectional study was conducted in four universities. A self-administered questionnaire was developed and validated. During clinical examination, acne severity was determined using the Comprehensive Acne Severity Scale (CASS) and psychosocial impact using the Cardiff Acne Disability Index (CADI).
Results: Four hundred students with acne aged 20±1.62 years participated, among whom 62.5% were women. The self-perceived acne severity matched the CASS score in 54.4% of the participants but was worse in 37.5%. Approximately 80.5% correctly recognised acne as a disease, while beliefs about its chronicity varied. The aggravating factors were food (92.8%), genetic predisposition (92.8%), stress (91.3%), hygiene (86.3%) and menstruation (84.8%). The information sources were families (79.7%), online social media platforms (60.2%) and friends (58.5%). Doctor consultation was significantly associated with correct disease perception, severe disease and higher psychosocial impact. Cost was the commonest deterrent for seeking (63.8%) and discontinuing treatment (43.2%). The psychosocial impact was predominantly mild (71%). The CADI domains mostly
affected were feelings and psychological state. The clinical (odd ratio [OR]=2.29, 95% confidence interval [CI]=1.45, 3.61) and self-perceived acne severity (OR=4.83, 95% CI=2.79, 8.35) predicted a higher psychosocial impact.
Conclusion: Misconceptions about acne as a disease were not prevalent, and aggravating factors other than food were correctly identified. Common information sources may further perpetuate misconceptions. Financial treatment barriers should be addressed especially in patients with severe acne and psychosocial impacts.

Published: February 2025

Introduction: About one-third of Malaysian adolescents engage in sexual activities before the age of 14 years, putting them at risk for unplanned pregnancies and sexually transmitted diseases. However, implementing sex education in Malaysia remains controversial and challenging. Therefore, this study aimed to develop and validate a newly gamified sexual and reproductive health (SRH) education module (ReReki) tailored for Malaysian adolescent boys.
Methods: The ReReki module was developed using the analysis, design, development, implementation and evaluation model, based on the theory of planned behaviour. Content validation involved six adolescent health experts, using Russell’s model validity approach and a content validity questionnaire. Games were then designed to complement the Sexual and Reproductive Health (SRH) materials. The gamified ReReki module was pre-tested with 20 adolescent boys from a selected school, and the language was refined by a linguistic expert.
Results: The module included five main topics, 29 subtopics and six games. The overall content validity score based on the survey method was 81.8%, while that based on Russell’s model was 79.3%, indicating a high level of validity for the ReReki module. One new topic and two subtopics were added, while two subtopics scoring below 70% were flagged for further review. The adolescent boys expressed their acceptance of the gamified SRH content.
Conclusion: All five main topics, along with the 29 subtopics in the ReReki module, are suitable and ready for use by adolescent boys in the Malaysian context.

Authors: Kyomo Robert Wilfred , Buhimila Juma
Published: February 2025

This case study examines the challenges faced by the Tanzania Revenue Authority (TRA) in its efforts to modernize tax administration and increase revenue collection. It focuses on the recent events including the nationwide traders' strike in June 2024, which exposed deep-seated issues within Tanzania's tax system. The study explores the complex interplay between the TRA's mandate to increase revenue and the business community's concerns about oppressive and unclear tax practices. Through an analysis of documentary evidence and stakeholder interviews, the case identifies key issues including tax evasion, complexity in tax laws, resistance to technological innovations like Electronic Fiscal Devices (EFD), and the informal sector's integration into the formal tax system. The study draws on theoretical frameworks such as the Gordon-Li Model, Lindahl's Model to contextualize these challenges. The study employed the case study research design and the sample size of 5 respondents who were purposely selected. This Case Study found that the TaxTech Ecosystem Initiative is a revolutionary approach to tax administration that leverages blockchain technology, artificial intelligence, and community engagement. This initiative aims to create a more transparent, efficient, and equitable tax system. The study concludes with recommendations for successful implementation, emphasizing the importance of stakeholder engagement, technological investment, phased implementation, inter-agency collaboration, data security, and continuous monitoring and evaluation. It suggests that if successfully implemented, this initiative could not only transform Tanzania's fiscal landscape but also serve as a model for other developing nations facing similar challenges in tax administration. This case study contributes to the broader discourse on tax administration in developing countries and provides insights into innovative approaches to addressing longstanding challenges in revenue collection and fiscal policy implementation.

Published: February 2025

Human waste management has been and continues to be a major global challenge facing urban growth. Even though sanitation is a human right, managing sanitation level is still a challenge. Most public toilets are in a mess and unhygienic forcing governments in different countries to incorporate private organizations into provision, management and maintenance. The main objective of this study was to determine availability of commercialized toilets in Kakamega town.  The research was carried out utilizing the Contract Theory. The study adopted descriptive research design carried out in Kakamega Town. The target population comprised residents of Kakamega town and those on daily transit thus 63,426 residents in addition to those in transit. Purposive sampling was done for Kakamega County town and key informants, while Simple random sampling was done for town residents and business people. Systematic sampling was conducted on individuals using public toilets. A sample size of 384 participants was used and data was collected using observation, interviews, questionnaires and document review. Data analysis utilized Statistical Package for Social Sciences (SPSS) version 28. Quantitative data was analyzed using descriptive and inferential statistics and qualitative data thematically. Majority of the respondents, 207 (58.97%) were of age bracket 21-30 years and males, 254 (72.36%). A total of 14 public toilets were located within the vicinity of Kakamega Town with 57.14% being commercialized and were not adequate. The rest were free to use public toilets.  265 (75.5%) of respondents knew of public toilets and their location with only 25.9% of females being very often users. Majority of respondents 256 (72.9%) chose public toilets because of their cleanliness and appearance. In conclusion, commercializing public toilets provided revenue and improved hygienic as well as aesthetic value of the town.  The study recommends the town to increase the number of commercialized toilet facilities within Kakamega Town. Since establishment of new counties in Kenya, such a study is yet to be done in Kakamega County and, therefore, would provide necessary baseline information to the county for policy implementation.

Published: February 2025

The Internet has become a vast repository of information, often filled with distractions that can hinder the user experience. News content, for example, is usually interspersed with advertisements that interrupt the flow of reading. In addition, the fast pace of news publication is also a challenge, with potentially more than 50 new articles appearing in 20 minutes. This high-speed data flow is valuable for various applications, including Social Media Analytics Services. In this context, the speed and efficiency of data acquisition (crawling) and processing (scraping) are critical. These processes must be optimized to ensure comprehensive data collection without gaps, focusing on the latest information. To meet this need, we propose developing an application capable of capturing news data in its entirety, minimizing the risk of missing important information. At the core of this solution is a web crawler- a sophisticated program designed to automatically browse the hyperlink structure of the web, systematically downloading linked pages to local storage. This crawling methodology is often the basis for web mining initiatives and search engine development. Since web information is distributed across billions of pages hosted on millions of servers worldwide, our application utilizes the PHP programming language to capture and process this data effectively. The main goal is to present pure news content to users without any irrelevant elements. We use a Data Flow Diagram (DFD) to model the system architecture and data flow. This approach provides a clear visualization of how web users can navigate through hyperlinks to efficiently access the desired news information. By implementing this system, we aim to improve the user experience of consuming news content, facilitate more effective data analysis, and contribute to the broader web information search and processing field.
Ülkemizde Eğitim Yönetimi Disiplininin Tarihsel Süreç İçerisindeki Gelişiminin İncelenmesi
Authors: Kıcır İsmail
Published: February 2025

The aim of this study is to examine the development of the discipline of educational management in our country within the historical process. One of the elements that can contribute to the scientific development process of disciplines is their interaction with other disciplines. According to the working principles, the relations of disciplines with other disciplines are sometimes divided, sometimes united, sometimes intersected. Thus, the boundaries of disciplines sometimes intersect or separate. Such interactions of disciplines have brought with them different conceptualizations. Some of these conceptualizations have been classified as interdisciplinary (interdisciplinary), multidisciplinary (multidisciplinary), transdisciplinary (transdisciplinary). Dec. In a multidisciplinary approach, disciplines maintain their own boundaries. In this regard, there is little interaction between the disciplines in terms of topics and cooperation.Dec. In this approach, the focus is on the result and efforts are combined as a result of each discipline working separately. In this regard, a multidisciplinary approach is characterized as additive. It is important for an activity or application field to gain an institutional structure in the transformation into a science field. From this point of view, scientificization and institutionalization, especially educational management and educational science, are seen as an ontological issue. It is expected that a field will have a number of developments in order to transform from an application field to a scientific field. This situation is especially important in the field of educational management and educational science. According to the Gulbenkian Commission, the elements that stand out in the scientificization and institutionalization of a discipline are the presence of the relevant discipline in universities (chair), scientific journals, scientific activities, cooperation of academics involved in the discipline and publications belonging to the discipline. In this context, it is possible to consider education management in Turkey as a discipline. In the studies, reviews and researches conducted on the subject in our country, the scientification and institutionalization of the field of education management in general has been examined through the prohibitive and supportive elements.

The title of this current study is Social Rejection and Inequitable Rights of Intersex Individuals: A Qualitative Study. The aim of the study is to understand the life led by intersex and highlight the problems faced by them to move towards for the better and equitability of the community in society. Intersex Justice Project (2020) reported that intersex activism and advocacy efforts aim to promote awareness, acceptance, and inclusivity. The research by Kamazima et al. (2023) study aims to examine the role of political elite in recognizing, respecting, protecting, and affirming the human and citizenship rights of intersex individuals in Tanzania. Saima et al. (2024) research stated that social rejection is a significant predictor of psychological distress. Qualitative data are the conceptual data and non-numerical data that are gathered by the observation and literature review of the book. We used this approach of qualitative study. In this current study, relational content analysis was used. It is a type of analysis that shows the relationship between the variables and theme. The outcomes of the study showed that society discriminates and stigmatizes, which leads to inequitable rights and social rejection. The experiences faced by the intersex cause inadequate mental well-being, which leads to bad physical health. Even the intersex community does not get the basic need treatment equally in hospitals, educational institutes, and legal departments on the basis of misconceptions about intersex and transgender people. The rejection of society enhanced the bad mental health of the intersex community. The current study is very effective for the betterment of intersex careers in the private and public sectors of the country. This study evaluated advocacy narratives representing how popular movements affect public views and fuel the need for fair rights for the intersex community. Collaboration with political and religious leaders should be carried out to ensure the removal of superstitious thoughts about intersex individuals.

Authors: Bogdan Itu Rãzvan , Soica Alexandra
Published: February 2025

Power grids have been the mainstay of power systems for more than a century, supporting economic activity by bringing power to homes, industry and services. As the transition to green energy advances, the role of electricity will become more important, making power grids even more special to society and economies. The energy sector is going through essential changes such as decarbonization, digitalization, climate change etc. and as a solution, governments, industries and other stakeholders will need to establish new policies, regulations and updated market models for a new system in the future. Therefore, our purpose was to develop a system that can track the sun from sunrise to sunset, which can be placed in a specific location to record and store data about the maximum potential sun that can be produced. The solar tracker is guided by two step-by-step motors, creating horizontal and vertical movement so that the rising sun will fall perpendicular to the solar panel. The two motors are controlled with the mobile phone which stores data about the amount of energy that is produced. A prototype was made using parts from reused materials such as bicycle wheel, concrete mixer crown, computer elements, parts for chairs, etc. The system is independent of electricity, so it can be placed anywhere without being connected to an outlet. The motors and the data controller are powered by the energy produced by the solar panel in the form of a closed circuit.

Photocatalysis has emerged as a sustainable and efficient approach for the treatment of industrial wastewater, offering the potential to degrade persistent organic pollutants under light irradiation. This study explores the enhanced photocatalytic degradation of textile wastewater using a TiO2-based nanocomposite photocatalyst. The composite was synthesized by modifying rutile TiO2, derived from natural rutile ore, with multi-walled carbon nanotubes (MWCNTs) through a hydrothermal process. The microstructure, morphology, chemical composition, surface area, and phase structure of rutile-TiO2, MWCNTs, and the TiO2/MWCNTs nanocomposite were characterized using different characterization techniques including high-resolution transmission electron microscopy (HRTEM), high-resolution scanning electron microscopy (HRSEM), UV-Vis spectroscopy, Brunauer-Emmett-Teller (BET) surface area analysis, and X-ray diffraction (XRD). Photocatalytic activity was evaluated by measuring the degradation of organic pollutants, with chemical oxygen demand (COD) and phenol concentration as indicators, under both artificial and natural sunlight irradiations. The results revealed that the incorporation of MWCNTs significantly enhanced the photocatalytic performance of rutile TiO2. Under visible light, phenol removal efficiencies were 59% and 42% for the TiO2/MWCNTs nanocomposite and rutile-TiO2, respectively, while under sunlight, the removal rates increased to 73% and 56%. Similarly, COD reduction was 55% for TiO2/MWCNTs compared to 35% for rutile-TiO2 under visible light, and 73% versus 56% under sunlight. These findings demonstrate that MWCNT modification improves the photoactivity of rutile-TiO2, offering a cost-effective and sustainable approach to wastewater treatment using photocatalysts derived from natural ore.

Os óleos essenciais são compostos voláteis extraídos de diversas partes das plantas e desempenham um papel importante na medicina tradicional e na indústria, especialmente na Amazônia. No Brasil, a exploração desses óleos é historicamente significativa, destacando-se a produção de óleos de andiroba, breu-branco, buriti e copaíba. Esses óleos possuem uma ampla gama de propriedades terapêuticas, como ação anti-inflamatória, antimicrobiana, antioxidante e cicatrizante, além de aplicações em cosméticos e na indústria farmacêutica. A exploração desses recursos naturais, no entanto, enfrenta desafios relacionados à sustentabilidade. A extração predatória de algumas espécies, como o pau-rosa e a andiroba, pode levar à degradação ambiental e ao risco de extinção de plantas nativas. Além disso, pesquisas recentes apontam novos usos dos óleos essenciais, como a redução da carga viral de doenças como a COVID-19, controle de doenças em vegetais e no tratamento de animais. Com o crescente interesse por produtos naturais e sustentáveis, os óleos essenciais da Amazônia têm o potencial de se tornar uma fonte importante de desenvolvimento econômico e conservação ambiental, destacando a importância de um equilíbrio entre exploração e preservação.

Introdução: A diversidade cultural refere-se a diferentes costumes de uma população. No ambiente escolar, ela instiga o respeito ao próximo e catalisa mudanças sociais positivas. Assim, os acadêmicos de medicina abordaram com os infantes o tema Copa do Mundo, visando a promoção da sociabilidade para apresentar o conhecimento da diversidade cultural das nações e o respeito ao diferente.  Objetivo: Relatar a experiência de uma ação educativa desenvolvida com foco na promoção da diversidade sociocultural na temática da Copa Mundial. Metodologia: O projeto extensionista ocorreu no segundo semestre de 2022 em uma escola municipal local, apresentando para 120 crianças a diversidade cultural relacionada à Copa do Mundo. Primeiro, os graduandos levaram globos de isopor que simbolizavam a Terra e bandeiras para colarem com as crianças, induzindo uma noção geográfica. Depois, selecionaram três países para elucidar sua cultura: Japão, apresentando a importância do origami; Moçambique, destacando seus costumes e brincadeiras típicas; e Brasil, revelando sua diversidade, comidas locais, fauna e flora. Resultados e discussões: A dinâmica teve boa adesão pelos infantes e demonstrou-se eficiente, sendo as crianças beneficiadas na edificação do saber geográfico, cultural, social, psicossocial e ético; e, os graduandos, em uma experiência trabalhada na dialogicidade e na humanização da formação individual e profissional, integrando-os com a comunidade. Conclusão: A prática viabilizou que as crianças construíssem, por meio de um aprendizado lúdico com o uso da Copa do Mundo, conhecimentos relacionados à diversidade dos países e o respeito às diferentes culturas, configurando uma prática de ensino alternativa efetiva pré-escolar.

A intensificação do uso das Tecnologias Digitais da Informação e Comunicação (TDIC) durante a pandemia transformou as relações laborais na sociedade contemporânea. Nesse contexto, a incorporação dessas tecnologias no trabalho e nas escolas tornou-se imprescindível, apesar dos problemas psicossociais que podem surgir. Nesse cenário, o objetivo foi identificar as produções acadêmicas que abordam a temática das representações sociais acerca do tecnoestresse docente. A metodologia utilizada foi de natureza qualitativa, com o intuito de mapear o estado do conhecimento sobre esse objeto de estudo. A revisão foi realizada nos periódicos da CAPES, no período de 2009 a 2024. As escolhas basearam-se na leitura dos títulos e resumos, seguidas pela aplicação de critérios de inclusão e exclusão. Os resultados apontaram uma escassez de pesquisas acadêmicas no Brasil que investiguem as representações e o tecnoestresse docente. Observou-se que o uso excessivo das TDIC traz efeitos negativos, manifestadas em dimensões como sobrecarga, conflitos entre trabalho e família, exaustão, ansiedade e fadiga. Conclui-se que, embora os resultados tenham fornecido insights valiosos, pesquisas futuras são essenciais para aprofundar a compreensão dessa relação, no que diz respeito ao impacto das tecnologias na saúde mental e no desempenho dos docentes.
Produção de sentidos da capulana em dois romances de Paulina Chiziane

Essa discussão segue o pressuposto metodológico da Análise do Discurso para descrever e analisar fragmentos das obras literárias Balada de Amor ao Vento e Niketche: Uma história de poligamia, da autora moçambicana, Paulina Chiziane. Considera os sujeitos que falam e as situações em que produzem o dizer, e propõe uma compreensão de como o objeto simbólico do texto - capulana, produz sentidos, ou gestos de sentido que o analista deve ser capaz de compreender. As narrativas mostram o entrecruzamento de muitas matrizes culturais e apresentam a capulana a partir da acomodação do tecido, nos dizeres de duas personagens femininas, Rami e Sarnau, e dialoga as subjetividades discursivas femininas. Na relação do implícito com os explícitos, o conhecimento atribuído por um locutor ou para um interlocutor acontece nesse movimento do explicito com o implícito. O processo discursivo se constitui como resultado de uma situação discursiva, de enunciados realizados – efeito de sentido; os sujeitos estão na ordem com a qual se comunicam. O análise foi realizada a partir de seleção de sequencias discursivas e a produção de efeitos de sentido no texto literário.

A transcrição de manuscritos históricos continua a ser uma tarefa desafiadora, especialmente para documentos em português, devido a diversos fatores que afetam a precisão das tecnologias de Reconhecimento Óptico de Caracteres (OCR). Entre os desafios, destacam-se a qualidade dos documentos, que muitas vezes apresentam degradação, artefatos, caligrafia complexa e variações linguísticas ao longo do tempo. Esses fatores dificultam a extração automática de textos precisos a partir de manuscritos antigos. Este estudo avaliou o desempenho de três ferramentas disponíveis de OCR: Google Vision, Docsumo e Transkribus. Cada uma dessas tecnologias tem abordagens para reconhecimento de texto, utilizando técnicas de inteligência artificial e aprendizado de máquina. O estudo de caso tem como objetivo não apenas testar as ferramentas disponíveis, mas também destacar os desafios encontrados na obtenção de transcrições confiáveis e precisas de manuscritos históricos em língua portuguesa. Os resultados mostram que, embora as ferramentas apresentem bons desempenhos em textos impressos ou modernos, a transcrição de manuscritos históricos ainda exige melhorias significativas. Assim, torna-se fundamental o desenvolvimento contínuo da tecnologia de OCR com auxílio da inteligência artificial para lidar com particularidades da escrita manual, promovendo maior acessibilidade e preservação da documentação histórica.
Research on the Inheritance and Dissemination of Intangible Cultural Heritage of Ethnic Minorities from the Perspective of Cultural Ecology
Authors: Chi Daoyuan
Published: February 2025

Intangible cultural legacy is a crucial part of ethnic cultural variety and social memory. Globalization and modernity are posing significant threats to ethnic minority' intangible cultural heritage. Cultural ecology gives a macro view on the evolution, adaptation, and survival of cultural legacy in specific contexts. The purpose of this research is to investigate how to successfully maintain and inherit ethnic minorities' intangible cultural assets from a cultural ecology viewpoint, as well as the dissemination methods that will assure their long-term growth. Cultural ecology views the inheritance of intangible cultural legacy as requiring a healthy ecological context. This covers not just environmental conservation, but also socioeconomic circumstances, education, policy support, technical advancement, and national self-identity. According to research, it is critical to build a multi-level inheritance system involving government, community, schools, and media through multi-party collaboration. In terms of communication, current media technologies such as the Internet, social platforms, and multimedia devices offer new and expanded opportunities for the promotion of intangible cultural assets.
