Authors: Nascimento Mário do Amaral , Oriol Ettore de Carvalho
Published: December 2024

Learning Analytics (LA) is a field that uses statistical analysis of educational data to improve learning processes' effectiveness, efficiency, and satisfaction. With the improvement of technologies and the increase in distance learning courses, Learning Analytics has grown considerably. This article discusses successful applications in public administration. It had to reorganize itself to continue serving its employees based on a financial need to reduce the number of licenses contracted for an e-learning platform for technological courses. Based on a statistical survey, various problems were identified, such as idleness, excessive workload, courses that needed to be more suited to the position of the job, and the distance between the manager and the needs. With the use of LA, it was possible to plan, distribute, and control the use of contracted rotating licenses more efficiently based on various actions that changed the culture, rules, and way of using them implemented in the company, resulting in more efficient use, improving all the indicators, even with the reduction in licenses.

Introduction: Alzheimer's disease is a degenerative and progressive disease that acts on the central nervous system. It affects about 10% of people over 60 years of age and 40% of people over 80 years of age and its complications can lead to death. When causing moderate to severe cognitive decline, hospitalization of the patient may be necessary. Objective: To analyze the profile of hospitalizations for Alzheimer's disease in Brazil from January 2003 to December 2022. Methodology: This is an ecological, retrospective and quantitative study. Sociodemographic data (gender, color or race, and age group) and clinical data (number of hospitalizations, average length of stay, total value of hospitalizations, deaths, and mortality rate) were analyzed. Results: A total of 19716 hospitalizations were observed in Brazil, most of whom were female (64%), over 80 years of age (56%) and white. The Southeast had the highest average length of stay (121.6 days); the total number of deaths during the analyzed period was 3831, with the Northeast having the highest mortality rate (26.2%). The total expenses were R$ 38596519.60. Conclusion: There is evidence of a progressive increase in hospitalizations for Alzheimer's disease in recent decades, which also impacts the increase in expenses. Elderly people over 80 years old were the most hospitalized, as well as women and white people. In the Southeast region, most deaths from Alzheimer's disease occurred. Strategies based on awareness of the disease are necessary to confront it.

Published: December 2024

Dental health is fundamental for overall well-being, affecting individuals' functional capacity, self-esteem, and quality of life from childhood. Caries, an infectious and chronic disease, are prevalent across all ages and especially common among children. This research at the “Hispano América” educational unit in Ambato aims to evaluate the determinants of cariogenic risk in school-aged children using fuzzy cognitive maps. The study, with a cross-sectional observational and descriptive design, employs a caries assessment tool questionnaire to identify cariogenic risk factors, such as dietary habits and oral hygiene practices. A stratified random sample of children was conducted, and interviews with parents and caregivers were carried out. The obtained data were analyzed using statistical techniques, which helped model the interactions between risk factors. The results indicate that limited access to dental services and high sugar consumption are the main determinants of cariogenic risk. Additionally, deficiencies in dental hygiene practices and oral health education were identified. Comprehensive strategies are proposed, including improving access to dental services, promoting oral hygiene habits, and ongoing oral health education both at home and in school. The study highlights the importance of addressing cariogenic risks in a personalized manner and emphasizes that effective interventions significantly improve dental health and quality of life for children

Published: December 2024

The struggle of the Indramayu people against Japan occurred in the context of the social, economic and political oppression experienced under Japanese rule. Japanese policies such as forced labor, economic exploitation, and political and cultural control sparked popular anger and resistance. The resistance of the Indramayu people to Japanese rule was a reflection of the strong national spirit in achieving Indonesian independence. This research uses a qualitative approach with a focus on literature study analysis. Through literature studies, research reveals how Japanese policies during their occupation of Indonesia, including economic exploitation, political and cultural control, and military cruelty, caused extraordinary suffering for the Indonesian people. The forced rice handover policy was the main trigger for the resistance of the Indramayu people. In this period, people were required to hand over very high quotas of rice, which caused a heavy economic and social burden for them. The resistance of the people of Indramayu, especially in Cidempet Village, is clear evidence of the people's courage and unity in facing oppression. Despite facing great risks, including repressive measures from the Japanese government, the people of Indramayu remain steadfast in fighting for their rights. This resistance not only had a local impact, but also gave impetus to the independence movement throughout Indonesia. The impact of the resistance of the Indramayu people on the Indonesian independence movement was very significant. Apart from increasing national awareness and strengthening local power, this resistance also encouraged the expansion of the independence movement to other regions and inspired a spirit of struggle throughout Indonesia. The resistance of the people of Indramayu shows the important role of regions in the independence movement, and emphasizes that the spirit of unity, courage and sacrifice is a strong foundation in achieving independence.

Authors: Carpio-Bernido M. Victoria , Bernido Christopher
Published: December 2024

The current situation of Philippine education presents problems and challenges of staggering proportions. With old paradigms deemed insufficient, we present investigations of new structures that could boost the effectiveness of the Philippine educational system. These apply the key observation that, Money is not the problem. Culture is the problem. In particular, we address the questions: What programs can foster the highest levels of learning, creativity, and productivity while overcoming severe constraints of poverty, low standards of living, substandard learning conditions, and formidable cultural barriers? What programs can generate higher levels of human development for a country by cultivating a healthy, cultured, and socially responsible citizenship?
We present an innovative, differentiated, and target-oriented program for high-impact multidisciplinary learning in High School. Essential features include (1) Parallel Learning Groups (Modified Jigsaw Strategy), (2) Activity-based Multi-domain Learning, (3) In-school Comprehensive Student Portfolio, and (4) Strategic Study and Rest Periods. The program, implemented since school year 2002-2003 in a rural private high school in Bohol, proves to be a robust and workable scheme even in its initial stages. It is student-teacher-administrator friendly and can easily be modified and adapted to different levels of affluence (or poverty) in public and private high schools. Although implemented with the 2002 Basic Education Curriculum (BEC), the program is compatible with other curricula. The program has resulted in the progressive enhancement of cognitive and affective learning of students, with each year’s graduates, on average, exceeding the performance levels of the previous year. This is shown by external checks of performance such as the number of students who pass the University of the Philippines College Admission Test (UPCAT).

Os temas que envolvem saúde e ambiente ganharam nas últimas décadas crescente importância em razão de crises ecológicas de larga escala. No estado de São Paulo, as duas primeiras décadas deste século envolveram um conjunto de demandas sanitárias associadas às questões ambientais que impõem novas estratégias de vigilância para proteção da saúde da população. Nesse período, questões como a das áreas contaminadas e de outros fatores de risco à saúde relacionados às substâncias químicas, a da poluição doar, a da potabilidade da água e das suas conexões com a degradação dos mananciais, a das mudanças climáticas e da escassez hídrica, a dos desastres naturais e tecnológicos, a dos eventos de massa, entre outras, adquiriram maior amplitude, mobilizaram a opinião pública e requerem cada vez mais estruturas e políticas públicas condizentes com os desafios que se avolumam. Em São Paulo, a vigilância de fatores ambientais de risco à saúde tem como referência histórica o Centro de Vigilância Sanitária (CVS), órgão vinculado à Coordenadoria de Controle de Doenças (CCD) da Secretaria de Estado da Saúde (SES), que, nestas duas últimas décadas, tem procurado aliar os clássicos padrões de atuação consolidados na legislação sanitária paulista com os novos modelos que vêm sendo estruturados no plano nacional sob a denominação de Vigilância em Saúde Ambiental (VSA). O artigo descreve e analisa os assuntos mais emblemáticos que, no período, se impuseram na sociedade paulista como demanda para VSA, procurando demonstrar que periódicos de caráter técnico‑científico, como o Boletim Epidemiológico Paulista (BEPA), são relevantes para a produção e a divulgação do conhecimento nessa área de saúde pública.

Published: December 2024

A área da Educação Matemática Inclusiva vem ampliando suas pesquisas, numa perspectiva de atender a todos, respeitando suas diferenças. Nesse cenário, o presente artigo está contextualizado a partir de uma investigação realizada em uma escola especial de surdos, tendo como sujeito uma aluna com surdocegueira congênita. O objetivo aqui é descrever e analisar cinco atividades desenvolvidas com a aluna, referentes a um dos processos mentais vinculados à construção do conceito de número, a saber, o processo de inclusão. O artigo apresenta uma contextualização da pesquisa e uma síntese sobre a surdocegueira, tendo a pesquisa desenvolvida numa perspectiva qualitativa, desenvolvida como um estudo de caso e analisada a partir da análise de vídeos. Como resultado destaca-se que a aluna realizou algumas atividades com facilidade, como colocar os objetos em seu respectivo cenário. Algumas atividades foram realizadas após tentativa e erro, como a inclusão dos cubos, porém sem considerar as informações dos números contidos nos objetos. Por fim, em duas atividades a aluna não conseguiu identificar o grupo que era definido pelas imagens, como os super-heróis, e não conseguiu compreender o grupo das tampinhas e os seus subgrupos. Nessas atividades, percebeu-se a dificuldade da aluna de pensar no grupo maior em relação aos grupos menores, processo importante do desenvolvimento, que envolve a classificação operatória a partir de inclusões hierárquicas. Conclui-se que mais pesquisas sobre a surdocegueira na perspectiva da Educação Matemática Inclusiva devem ser realizadas, ampliando a discussão sobre a temática.

Published: December 2024

O mapeamento de uso e cobertura da terra é um fator importante na análise geoespacial na gestão de bacias hidrográficas. A integração de imagens de sensoriamento remoto e técnicas de classificação por Aprendizagem de Maquinas viabilizam a identificação e monitoramento ambiental dos elementos da paisagem. Neste estudo, foram desenvolvidos nove modelos de dados para a classificação do uso e cobertura da terra por Random Forest em uma sub-bacia hidrográfica do Rio Terra Nova no estado de Pernambuco, usando uma cena do sensor de imageamento orbital AVNIR-2 (Advanced Visible and Near-Infrared Radiometer-2) do satélite ALOS-2. Esses modelos foram criados com base nas bandas AVNIR-2 e quatro índices de vegetação e no ranking de importância de variáveis através do índice de Gini. A avaliação dos resultados foi feita por meio da quantificação espacial e análise de acurácia. No geral, as variabilidades de recursos espectrais não foram capazes de impulsionar mudanças bruscas na qualidade da classificação. As classes de Vegetação apresentaram acurácia do produtor acima 85% para todos os modelos, enquanto as classes de Área Não Vegetada e Água mostraram um declínio nos valores de acurácia do produtor e usuário correspondente a diminuição de recursos espectrais. Este estudo é o primeiro a usar adaptações de dados espectrais do AVNIR-2 e métodos de aprendizado computacional para demonstrar a aplicação de mapeamento de cobertura do solo de alto desempenho, além de contribuir para o monitoramento da superfície do solo em bacias hidrográficas que necessitam de informações espaciais precisas sobre o estado conversação ambiental.

Published: December 2024

Indonesia is a tropical region experiencing rapid industrial growth. Gresik City is located in East Java Province, Indonesia, and is recognized as an industrial area with major activities including nickel and steel smelting, electronics, petrochemicals, and energy production. Sukorejo and Gulomantung villages in Gresik City are coastal areas with residential conditions surrounded by industries. Industrial and residential activities in Sukorejo and Gulomantung villages emit CO2 emissions, which can enhance the greenhouse effect. One of the initial steps in controlling greenhouse gases is through the assessment of aboveground biomass and the calculation of carbon stocks. This study estimates carbon stocks from vegetation in Sukorejo and Gulomantung villages to absorb CO2 emissions from industrial and residential activities in June to August 2023. Calculation of CO2 emissions uses data on energy consumption and electricity usage from industrial and residential sources. CO2 emissions are estimated absorbed by vegetation using allometric carbon calculation equations. Calculation of carbon stocks is based on aboveground biomass (AGB) of vegetation. The estimation of AGB is conducted using allometric equations based on wood density and diameter at breast height (DBH). The research findings indicate that the total CO2 emissions from industrial and residential sources in the villages of Sukorejo and Gulomantung amount to 165 196.14 tons/year. The carbon stock in Sukorejo and Gulomantung total 2871.74 tons/ha with a CO2 absorption capacity of 22 403.68 tons/year, resulting in 142 792.46 tons/year of unabsorbed CO2. Increasing the planting of large shade trees in Gulomantung is necessary due to the availability of extensive vacant land. This study concludes with two optimal scenarios: scenario 1 involves adding one tree species, while scenario 2 consists of a combination of six large shade tree species.

The evolution of air quality in the city was examined over the period from 2000 to 2011. During this period, a number of heavy industries in the city were closed down. Consequently, an investigation was conducted to ascertain the impact of the gradual closure of industrial units in the city on the evolution of air quality. The analysis of the evolution of daily and monthly average concentrations of PM10 and SO2 in the city over the years, from January 2000 to December 2011, indicates a general improvement in air quality levels throughout this period. The results demonstrate that following the closure of certain industrial facilities, the mean concentrations of PM10 exhibited a decline of 33.30% and 26.50%, respectively, at the Escavadeira and Lavradio air quality (AQ) stations within the city. Similarly, the mean concentration of SO₂ decreased by 64.70% and 84.60%, respectively, in the same AQ stations. With regard to the maximum values (peaks) of PM10 concentrations, a decrease of 40.90% and 26.50% was observed in the analysed AQ stations, while SO2 maximum concentrations (peaks) decreased by 61.30% and 89.60% in the same AQ stations. This evaluation revealed a significant enhancement in air quality following the closure of numerous industrial facilities.

Microclimates are important for understanding the impact of urban areas on the environment. Although often overlooked, educational campuses cover large metropolitan areas that contribute to environmental harm in cities. This research focuses on studying the microclimate characteristics of Nawroz University’s campus in Duhok City, Iraq. The study uses ENVI-met software to assess current conditions and a proposed Green-Belt (GB) scenario. The analysis focuses on mean radiant temperature (MRT) and air temperature at four specific times (4 a.m., 8 a.m., 2 p.m., and 10 p.m.). A comparison is made between a Baseline scenario and a Green-Belt scenario. The Baseline scenario shows high temperatures on sun-exposed surfaces. The Green-Belt scenario demonstrates temperature reductions at 2 p.m. up to 8°C, highlighting the importance of vegetation in mitigating heat. Temperature reductions of 3°C to 5°C were also observed at 8 a.m., underscoring the cooling benefits of the proposed vegetation. The results from the Baseline scenario indicate that surfaces exposed to the sun with low albedo have higher temperatures. Vegetation in urban planning improves campus thermal comfort, reducing urban heat island effects. The study highlighted green infrastructure potential in creating sustainable urban environments, notably in regions transitioning to sheltered areas adjacent to trees.
Multi Objective Optimisation of Metal Die Support Incremental Sheet Forming of SS 316L Sheets using Taguchi Grey Relational Analysis
Authors: ARJUNAN Visagan , PASUPATHY Ganesh
Published: December 2024

The Metal Die Support Incremental Sheet Forming (MDS-ISF) enhances the dimensional accuracy of produced items in many industrial applications. However, the procedure limits metal sheet formability due to the strain between the tool and mandrel. As a result, selecting the best MDS-ISF technique to improve formability is a critical problem in the manufacture of complicated components. This study aims at optimising the forming parameters of MDS-ISF by forming single-walled cones of fixed wall angle and forming height by using Taguchi Grey Relational Analysis. The forming parameters selected for experimentation are step depth, spindle speed, and feed rate at three different levels. The responses, such as average surface roughness and average thickness, were selected for multi-objective optimisation and ANOVA was also conducted to study the influence of each forming parameter on the output responses. Additionally, the wall angle, and thickness of the components were also measured. From ANOVA, step depth had the uppermost influence on the surface finish and thickness trailed by feed rate and spindle speed.
Reimagining Time and Narrative: Indigenous Temporalities and Social Critique in Rebecca Roanhorse’s Trail of Lightning
Authors: Wieczorek Paula
Published: December 2024

This paper explores how Rebecca Roanhorse’s Trail of Lightning reimagines time from an Indigenous perspective, offering a counter-narrative to the linear, clock-driven concept of time prevalent in Western thought. Through a close analysis of the novel mentioned above, the study examines Roanhorse’s integration of cyclical time, mainly through narrative techniques like flashbacks, oral storytelling, and depictions of deep time. These elements disrupt conventional linear storytelling and emphasise the interconnectedness of time, history, and the environment as seen from an Indigenous worldview.Moreover, the paper discusses how these Indigenous temporalities intersect with crucial themes in the novel, such as colonialism and environmental degradation. This intersection provides a nuanced perspective on the dystopian realities Roanhorse portrays, encouraging readers to question and rethink the dominant temporal frameworks that often contribute to environmental and social crises. By challenging these frameworks, Trail of Lightning invites us to consider a more holistic and sustainable approach to time—one that acknowledges the continuous flow of stories and events that shape our past, present, and future. In terms of methodology, the paper draws on insights from Indigenous studies scholars, including Kyle Whyte, and research from the environmental humanities to frame its analysis.
»Du stellst meine Füße auf weiten Raum«
Authors: Link Hans-Georg
Published: December 2024

The ecumenical theologian of Cologne Hans-Georg Link describes in his new book the broad area of the last 50 years from 1974, in which he gathered abundantly his ecumenical encounters and experiences. He summarizes them under five aspects: biographical approximations, visits to six continents, experiences with other churches, local ecumenism, and perspectives for the 21st century. Link puts a special accent on the project of the Commission on Faith and Order dealing with Apostolic Faith Today, which he was responsible for at the World Council of Churches (WCC) in Geneva. He spreads a wide sweep from the 1st Council with its ecumenical Creed of Nicaea – Constantinople 325/381 at that time to its 1700th anniversary in the next year 2025 with proposals for interpretation and formation today. This interesting book begins with a meditation on Pentecost according to Acts 2: »The Spirit helps us in our Weakness«, to make sure that the ecumenical ideas and proposals are well understood.
An Updated Review of Optimal Threonine Requirements in Broiler and Indigenous Slow-Growing Chickens
Authors: Manyelo Grace , Wilfred Ng’ambi Jones
Published: December 2024

Broiler chickens are nutritionally, economically, and culturally very important. Thus, broiler chickens are continuously and efficiently being bred to grow fast. This means that diets, also, must be continuously formulated to meet the nutrient requirements of the genetically improved chickens. Thus, diets with nutrient levels for optimal chicken performance are required. Chickens on diets with low threonine levels have poor growth performance. Studies for dietary threonine requirement levels for optimal performance of slow-growing indigenous chickens are limited and contradictory. This chapter reviews studies on threonine levels for optimal performance of broiler and slow-growing indigenous chickens. Dietary threonine requirements levels for optimal performance of broiler and slow-growing chickens depend on the particular variable in question. Dietary threonine requirements for optimal performance decrease as chickens grow older because older chickens have lower threonine requirements for growth. Dietary threonine requirement levels for optimal performance of broiler chickens are higher than those for slow-growing chickens, possibly indicating threonine requirement level differences for genotype and growth level. It is suggested that there is a need to continuously conduct studies aimed at determining threonine levels for optimal performance of broiler and slow-growing indigenous chickens as threonine requirement levels change due to genetic improvements of the chickens.
Co-Production of Hydrogen and Methane by Anaerobic Digestion
Authors: Yin Fang , Ji Junlin , Zhang Wudi
Published: December 2024

According to the analysis of material metabolic pathway, mutual symbiotic flora, and energy cooperative sharing, the paper proposed that the ideal anaerobic digestion metabolism process of hydrogen production followed by methane production coincided with the mutual symbiotic and synergistic mechanism. (1) Hydrogen, carbon dioxide, and acetate acid are the important intermediates in the process of anaerobic digestion for co-production of methane and hydrogen. (2) Hydrogen-producing acetogenic, bacteria and hydrogen-consuming methanogenic bacteria undergo mutual coupling to become the anaerobic symbiotic compact, sharing organic material degradation and contributing chemical energy (15 kJ/mol). (3) From the point of view of adenosine triphosphate (ATP) energetics, we explain the phenomenon of low energy dissipations of anaerobic digestion, which is about 20 kJ/mol of energy requirements for symbiotic community survival. The viewpoint of mutual symbiosis was supported by the typical case of mutual symbiotic community in the 1960s and H2 hypothesis in the 1970s’ which also verified the optimal energy conversion efficiency of co-production of hydrogen and methane.

Probiotics are microorganisms used in the food and pharmaceutical industries to improve the nutritional quality of foods, preserve them, produce antibiotics and fight against certain pathogenic strains. Probiotics are also microorganisms with beneficial effects. The most commonly used are lactic acid bacteria (LAB). These have been the subjects of numerous studies in food and medicine. Recently, the advent of new technologies has enabled the selection, development, and demonstration of the probiotic aptitude of other microorganisms such as viruses (phagebiotics) and molds. The probiotic ability of the latter has been demonstrated by in-vitro and in-vivo tests. Phagebiotics are used for their functional properties, especially against multi-resistant bacteria, for the reduction of Clostridium difficile spores and Pseudomonas aeruginosa. Thus, certain molds, which are used as probiotics, are capable of reducing cholesterol. This chapter shows the possibility of using probiotic microorganisms as an alternative to antibiotics for the treatment of certain human and animal pathologies or the detoxification of foods contaminated by mycotoxins.
