A ditadura militar no Brasil e a censura a obras de autoria de artistas mulheres engajadas
Authors: Da Silva Lopes Almerinda , Ribeiro Roney Jesus
Published: November 2024

O artigo reflete acerca do engajamento político de artistas mulheres na ditadura militar e o empenho do poder público para censurar e reprimir suas ações sociais. Trata-se de um texto, que se embasa em uma pesquisa teórico-metodologicamente qualitativa, que se respalda na revisão de aportes bibliográficos sobre a Ditadura Militar, sobre engajamento feminino ou feminista, no levantamento, observação e análise de obras produzidas por artistas mulheres, que sofreram algum tipo de interferência da censura, no período de 1967 a 1975, período esse marcado pelo enrijecimento da repressão, da perseguição e da violência policial e prisão de intelectuais, estudantes, jornalistas, sindicalistas e artistas. Se logo após o golpe militar, algumas artistas engajadas acreditaram que por recorrerem a novas gramáticas visuais, linguagens, suportes e a materiais, que eram, então, pouco familiares aos agentes dos órgãos de repressão, o que as isentaria da ação da censura, a incompatibilidade entre arte e poder político logo se tornaria explícita. Embora o foco da abordagem se concentre nas artes visuais, faz-se também alguma incursão pela produção literária e musical, cujas autoras mulheres tiveram, igualmente, obras censuradas pelo regime.

Published: November 2024

A rápida urbanização, associada às emergências climáticas, é um desafio para o planejamento, a gestão urbana, o monitoramento e a fiscalização de ocupações inadequadas, especialmente em áreas de inundações. Objetivou-se investigar a dinâmica temporoespacial de uso e ocupação da terra em áreas críticas de perigo de inundação em Guarapuava (PR), de abril a novembro de 2023. Os procedimentos metodológicos incluíram a interpretação visual de imagens do Google Earth e ortomosaicos obtidos com um veículo aéreo não tripulado, referentes às áreas que necessitam de atenção pública. Os resultados demonstram aumento na impermeabilização do solo e no número de residências em áreas de perigo de inundação. Concluiu-se que a dinâmica de ocupação das áreas de perigo de inundação por edificações é rápida, excedendo muitas vezes a capacidade de monitoramento e fiscalização dos órgãos competentes. Portanto, além de um disciplinamento do uso e da ocupação do solo em áreas de perigo de inundação, faz-se necessária uma fiscalização eficiente, uma vez que uma maior exposição ao perigo aumenta o risco de desastres.
The Development of Science in Islam and Its Impact on Islamic Education
Authors: Yuniendel Ratna Kasni , Azhari Devi Syukri
Published: November 2024

Islam has a long history in developing science that began in the 7th century. This development was triggered by the teachings of the Qur'an and Hadith that encouraged the Muslims to demand knowledge and understand the universe. In the golden age of Islam (eighth to fourteenth centuries), centers of science such as Baghdad, Cordoba, and Cairo were the birthplace of many great scientists such as Al-Khwarizmi, Ibn Sina, and Al-Razi. They made significant contributions to a wide range of sciences including mathematics, medicine, astronomy, and philosophy. The influence of the development of science in Islam on Islamic education is enormous. First, education in Islam emphasizes the importance of a balance between religious science and general science. Second, many Islamic educational institutions, such as madrasas and universities, are established to facilitate the teaching of science in a comprehensive manner. Third, the curriculum of Islamic education often includes the study of science and technology, in addition to religious studies, to produce broad-knowing and critical-minded individuals. However, the development of science in Islam also faces challenges, especially in the modern era. These challenges include efforts to maintain the relevance of the Islamic educational curriculum to the development of contemporary science as well as the integration of technology into the learning process. Therefore, Islamic education needs to continue to adapt and innovate in order to remain able to make meaningful contributions to the world of science and remain relevant in the midst of changing times.

Published: November 2024

The transformation of education in Indonesia has become a central issue that continues to be discussed in the realm of national education. The government is trying to present a curriculum that is adaptive and relevant to the needs of the times, one of which is by creating the Merdeka Curriculum. Although the Merdeka Curriculum gives teachers greater authority, there is a lack of comprehensive research on how the conversion from CP to ATP impacts the concept of Merdeka Mengajar. This study aims to analyze the process of formulating CP to ATP with the aim of exploring the meaning of "Merdeka Mengajar" in more depth. Using content analysis, this study examines the Merdeka Curriculum documents, especially the process of converting CP to (ATP) in a case study. The Merdeka Curriculum provides space for educators to be creative in learning, but there needs to be a better mechanism to ensure alignment in achieving learning objectives. The flexibility of the Merdeka Curriculum has the potential to increase the relevance of learning, but also poses challenges in maintaining the quality and uniformity of student learning outcomes. The Merdeka Mengajar concept carried by the Merdeka Curriculum is to provide greater autonomy to teachers to plan and implement learning according to the conditions of students in achieving the CP of the curriculum.

This study used qualitative descriptive methods and surveys in five locations, with nutmeg nurseries as subjects. Data were collected through observation, interviews, and documentation, then analyzed by tabulation. Based on the study, the most nutmeg varieties in the nursery locations were Ternate 1, found in five locations: Maliaro, Tobololo, Sulamadaha, Loto, and Togafo. Ternate 1 nutmeg is superior because its seeds and maces are of high quality, with characteristics of regular branching, oval leaves, and round fruit. In addition, Makian Lokal and Tobelo 1 varieties are also present, although limited. Pala Gaji, which is only found in Tobololo, has white mace, different from other varieties which are red when ripe. The Ternate 1 variety is the most dominant because many of its parent trees are spread across Ternate. In five sub-districts in Ternate City, there are four nutmeg varieties: Ternate 1, Tobelo 1, Makian Lokal, and Pala Gaji. The Ternate 1 variety is the most dominant. Of the 24 nursery farmers, their income can increase two-fold or more depending on the number of seedlings produced.

Authors: Nasichah Muwafaqotun , Hasyim Ahmad Fuad , Sari Dakusta Puspita
Published: November 2024

The high unemployment rate of Vocational High School (SMK) graduates in Indonesia, reaching 22% of the total national unemployment, indicates a mismatch between graduate competencies and the needs of the business world and industry (DUDI). To overcome this problem, the Field Work Practice Program (PKL) is designed to strengthen the relationship between education and industry. This study evaluates the implementation of PKL on the Fashion Design Expertise competency of SMK Syubbanul Wathon Tegalrejo, a vocational school based on an Islamic boarding school that implements PKL based on Teaching Factory, using a descriptive qualitative evaluation method with the CIPP (Context, Input, Process, Product) approach. Data were collected through observation and interviews. The evaluation results show that in terms of Context Evaluation, SMK Syubbanul Wathon has adequate facilities and teaching staff to support the implementation of PKL. Input Evaluation shows that PKL planning and preparation are carried out well and in a structured manner, although there are limitations in human resources in the field of Fashion Design. In the Process Evaluation, the implementation of PKL went according to plan, but direct interaction between students and mentors from DUDI was still limited and mostly done online. Product evaluation revealed that some students successfully completed the project on time and showed increased competence, but others were still unable to complete the project on time. In addition, students gained new knowledge about the fashion industry and were satisfied with the internship experience, although improvements were needed in instilling a work culture. Overall, the implementation of the Teaching Factory-based internship with external mentors is still relevant and useful. Recommendations for further research include the development of more effective mentoring methods and continuous assessment of industry needs.

Published: November 2024

The low learning outcomes at SMA Negeri I Fatuleu are attributed to several factors that hinder learning development. Observations and interviews with Economics teachers revealed that many students still exhibit habits such as lack of attention, difficulty concentrating, frequent daydreaming, and failing to complete assigned homework. Additionally, some students consistently submit assignments late or fail to submit them altogether. This study examines the influence of family environment and peers on learning achievement, with 12 statements for family and 13 for peers, all valid and reliable. A prerequisite analysis was conducted and deemed feasible. Using random sampling, 50 respondents were selected. The study also applies Multiple Regression Analysis and supports various hypothesis tests. The regression analysis shows that the family environment and peers have a positive and significant effect on learning achievement, as indicated by the equation Y = 4.729 + 0.638x1 + 0.427x2. The constant value of 4.729 means that if both variables are zero, Y is 4.729. The family environment's coefficient of 0.638 signifies a significant influence with a Sig. value of 0.008 (<0.05). The study concludes that both family environment and peers positively and significantly influence learning achievement, with family providing motivation and peers offering support and collaboration.

Authors: Dourado Jovana , Tavares Neto Junior Ademar
Published: November 2024

Este artigo visa expor uma Sequência Didática, composta por quatro aulas de Língua Inglesa, elaborada no contexto do curso de Pós-Graduação em Ensino de Línguas do IFSP – Capivari, cuja temática permeia os patrimônios culturais e suas intrínsecas correlações com a valorização do plurilinguismo, de forma intercultural. O objetivo da Sequência Didática é propor um estudo analítico, com vias multissemióticas, das heranças culturais contextualizadas por diferentes povos, colaborando para uma reflexão crítica e respeitosa dos sotaques, para contrastá-los com a modalidade falada do inglês de prestígio. A proposta baseia-se no reconhecimento da diversidade linguística como direito a partir do status do inglês como língua franca presente na BNCC (BRASIL, 2018). Parte das abordagens de ensino comunicativa, segundo Schneider (2010), e intercultural segundo Candau (2008) e Maher (2007), reconhecendo, conforme Silva e Martins (2022), que as variedades oriundas da cultura dominante podem servir como instrumento de controle cultural e reprodução de preconceitos. Na primeira aula, o tema ‘patrimônio cultural’ é introduzido através da leitura de definições desse conceito, além de trabalhar com textos multimodais como placas turísticas e mapas mentais. Um vídeo da UNESCO sobre heranças culturais de diversos países e atividades de pré-escuta, escuta e pós-escuta são os recursos principais da segunda aula. Na terceira, propõem-se exercícios que abordam aspectos semânticos, morfossintáticos e traços prosódicos presentes no vídeo, abordando a língua de forma contextualizada. Por fim, os alunos são convidados a produzir um vídeo curto sobre um patrimônio local que pode ser utilizado como instrumento avaliativo. Com essa Sequência Didática, espera-se propiciar aos discentes compreensão e reflexão sobre a importância da herança cultural e a sensibilização para a valorização da heterogeneidade linguística do inglês falado, tendo em vista a diversidade e os hibridismos linguístico-culturais tão marcantes na sociedade contemporânea.
Metodologia e ruptura
Authors: Do Prado Flores Miguel Augusto , Ianuskiewtz Andréia Dias
Published: November 2024

Muitas vezes, verifica-se um quadro de desinteresse dos aprendizes pelas aulas de Língua Inglesa (LI) que pode ser ocasionado, dentre outros fatores, por procedimentos rotineiros adotados por professores que reproduzem atividades apresentadas em livros didáticos direcionados à aprendizagem do idioma, sem considerarem a possibilidade de serem atores no processo, nem tão pouco a autoria e singularidade dos alunos. A observação desse quadro despertou-nos interesse em pensarmos em metodologias de ensino de LI que possam provocar rupturas das práticas homogeneizantes (Bohn, 2013) geralmente utilizadas.

Published: November 2024

The objective of this study is to examine the relationship between tax knowledge, perception of tax fairness, and perception of trust on tax compliance behavior among public sector teachers in Malaysia. Understanding the factors that influence tax compliance is crucial for developing strategies to enhance voluntary compliance and improve tax revenue collection. Data was collected through online surveys distributed to 500 public sector teachers across Malaysia, with 216 valid responses obtained. The collected data was analyzed using SPSS, and Pearson Correlation was employed to assess the relationships between the variables. The findings reveal significant positive relationships between all three independent variables—tax knowledge, perception of tax fairness, and perception of trust—and tax compliance behavior. These results suggest that improving tax education, ensuring a fair tax system, and building trust in tax authorities can effectively encourage voluntary tax compliance. The insights gained from this study can inform policymakers on strategies to improve compliance rates and optimize tax revenue collection.

Authors: Al Khatib Inas , Ahmed Norhan , Ndyiaye Malick
Published: November 2024

While the UAE is making strides in healthcare digitalization and adopting global best practices, the absence of a unified data protection framework equivalent to the GDPR poses significant challenges for hospital management systems (HMS) in the region. This gap creates uncertainties in compliance, especially regarding cross-border data transfers, third-party vendor management, and the protection of patients' privacy rights. The lack of clear regulations tailored to the UAE’s unique healthcare landscape hinders the implementation of robust data protection measures, raising concerns about potential data breaches, legal liabilities, and the overall trustworthiness of healthcare institutions. Addressing these challenges is crucial for aligning the UAE’s healthcare sector with international standards while ensuring the security and privacy of patient data in a rapidly evolving digital environment. The General Data Protection Regulation (GDPR) has significantly impacted hospital management systems (HMS) by setting strict data protection requirements. This study provides a systematic literature review of GDPR compliance in HMS, focusing on key challenges such as regulatory complexity, permission management, data subject rights, data breaches, third-party vendor management, and cross-border data transfers. Suggested mitigation measures include privacy by design, data protection impact assessments, improved consent management, robust breach detection, and efficient vendor management. Legislative reforms are needed to clarify GDPR's application to healthcare. The study also highlights increased investments in privacy technologies, improved patient trust, and the demand for advanced solutions. Future research should explore the effectiveness of these mitigations, GDPR's impact on patient satisfaction, ethical data processing, and standardized data protection frameworks in healthcare. Achieving GDPR compliance is crucial for protecting patient data, building trust, and ensuring secure and ethical use of healthcare information. This study aims to guide healthcare organizations, particularly hospitals, along with regulators and researchers, in navigating these challenges and implementing effective solutions.

Optimization of Acetylcholinesterase and Sucrose Concentration using Response Surface Methodology (RSM) Approach in the Development of Paper-Based Biosensor for Pesticides Detection
Authors: Wijayanti Sudarma Dita , Novitasari Erlienda , Kusnadi Joni
Published: November 2024

Excessive use of pesticides, particularly organophosphate pesticides (OPs), to increase agricultural productivity may give a risk to consumers if consumed as these pesticides are neurotoxic substances. To increase agricultural productivity, fruits and vegetables are frequently treated with excessive pesticides, particularly organophosphate pesticides (OPs). Several methods have been studied and developed to identify pesticide residue in crops, however the standard laboratory procedures for OPs analysis involves the use of HPLC or GC-MS. These methods are complex in sample preparation and require expert labor to operate. Paper-based biosensors are low-cost platforms for fast detection in the field, offering an easy and reusable option. In this study, a colorimetric paper-based biosensor based on immobilizing acetylcholinesterase (AChE) using sol-gel silica matrices and indoxyl acetate is developed. The Response Surface Methodological (RSM) approach was used to optimize AChE concentration and sucrose as a stabilizer, allowing simultaneous optimization of multiple variables using smaller-size datasets. This study used the central composite design (CCD) fractional factorial design using Design Expert 7.0 software. A quadratic model was selected to represent both immobilization yield and relative AChE activity responses. The model was evaluated using ANOVA values and Lack of Fit test which confirmed that the quadratic models for both responses are suitable for experimental data. Validation of the model demonstrates that the predictive model accurately represents of the validation research. The Limit of Detection (LoD) of the biosensor for pure profenofos pesticide after a 20-minute incubation time is 1 ppm, as indicated by a 32.55 % decrease in color intensity. After a week of storage at 4 °C, the biosensor showed a loss of 5.92 % on immobilization yield and 2.55 % on relative activity indicating a good storage stability. The mean value of lettuce samples was 200.60 ± 1.2 a.u, with pesticide concentration of 2.57 ± 1.2 ppm (n=3).
HIGHLIGHTS

Incorporating AChE into the sol gel matrices is a great way to enhance the stability of the enzymatic colorimetric pesticide detection.
Response Surface Methodology (RSM) is considered as useful for optimizing response level of AChE and sucrose.
Combination of optimum AChE and sucrose concentration show beneficial effect on the stability of the biosensor.

Hydrogen Sulfide Concentration Influence Toward Uniform and Localized Corrosion Rate of API 5L X65 Steel at Elevated Temperature
Authors: Azhar Liyana Yasmin , Jarni Husna Hayati , Alauddin Sakinah Mohd , Othman Norinsan Kamil , Yaakob Najmiddin
Published: November 2024

Trace amounts of hydrogen sulfide (H2S) in a carbon dioxide (CO2) dominant environment reduce general corrosion rates by forming thin iron sulfide layers but increase localized corrosion. This study investigates how varying H2S concentrations affect the corrosion rates of API 5L X65 steel at 70°C. Using a 2 L glass cell setup, steel coupons were immersed in a solution containing 1,000 ppm NaCl and 500 ppm HAc for 7 d. Corrosion rates were determined through weight loss measurements, and surface morphology was analyzed using scanning electron microscopy and energy dispersive x-ray analysis. H2S concentrations of 0 ppm, 30 ppm, 60 ppm, and 100 ppm were tested. At 0 ppm H2S, the uniform corrosion rate was 2.53 mm/y. The addition of 30 ppm H2S reduced the rate to 1.00 mm/y, showing a 60% inhibition efficiency. However, the highest pitting corrosion rate of 6.30 mm/y occurred at 30 ppm H2S, with a maximum pit depth of 123 μm. The results suggest that lower H2S concentrations lead to localized corrosion, while higher concentrations form a protective film, reducing corrosion rates.

Este artículo sistematiza el proceso de investigación y de abordaje didáctico del proyecto museográfico "Infancia/Dictadura: Testigos y actores (1973-1990)" montado en su novena versión en 2023 en Santiago de Chile. Dicho proyecto representa la síntesis de una investigación académica que aborda la microhistoria de la niñez durante el periodo de la dictadura militar en Chile (1973-1990) a través de las producciones/objetos creados por niñas y niños durante la época y las formas de elaboración que los y las visitantes (niños, niñas, jóvenes y adultos/as) realizan de tales objetos. Se analiza el estatuto de los objetos producidos en la niñez como cultura material y su valor para la elaboración memorial de las nuevas generaciones a través del dominio estético. Los resultados de la experiencia indican que la experiencia museográfica contribuyó a actualizar la memoria colectiva sobre la dictadura en la articulación del pasado, el presente y el futuro en torno a la vulneración de derechos humanos, al reconocimiento de la complejidad de las construcciones memoriales diversas y resignificación en el presente, a la promoción del diálogo entre generaciones y a la expresión de emociones colectivas en el marco del cincuentenario del golpe de Estado.

En 2018 se sancionó en Uruguay la Ley No. 19,641 sobre creación y declaración de Sitios de Memoria Histórica del Pasado Reciente, promovida por el trabajo político de la sociedad civil organizada (colectivos de víctimas, familiares, activistas de la memoria y los derechos humanos, y sindicatos). El objetivo de este trabajo fue conocer y caracterizar la implementación de dicha normativa. Para esto, se analizaron cuantitativa y cualitativamente las características de los 44 lugares señalizados (homenaje o espacio represivo) y declarados como sitio de memoria (SM) entre 2018 y 2022. Los resultados muestran que la mayoría de estos constituyen marcas descentralizadas y que una mínima proporción de ellos se encuentra abierta al público. A su vez, los lugares donde se cometieron delitos de lesa humanidad son diferenciados en la práctica, no por su naturaleza, sino por su tipo de resolución (declaración de SM o señalización). Esto ha permitido concluir, que la implementación de la ley no ha mostrado -salvo en escasas excepciones-, la recuperación y refuncionalización en SM de los lugares auténticos.

En el contexto de la conmemoración de los 50 años del golpe de Estado en Chile, las preguntas sobre qué, cómo y desde dónde transmitir las memorias del pasado son acuciantes. En el campo de los estudios de memoria, las investigaciones sobre transmisión generacional se han situado en escenarios de postconflictos, focalizándose principalmente en los emprendedores de memoria, en lo que es transmitido, y en sus destinatarios. Considerando la complejidad político-social que la sociedad chilena enfrenta con el aumento de la polarización política y al hecho que desde las Ciencias Sociales se trabaja con "conceptos sensibles", en este artículo se problematiza el concepto de transmisión generacional a partir de dos investigaciones situadas en contextos donde el conflicto sigue presente, como es el caso de un barrio "emblemático" que devino en "crítico" y el de las movilizaciones que disputan el género. El análisis de datos producidos a través de observaciones participantes y entrevistas permite reconfigurar la noción de transmisión por la de conexión generacional, donde se requiere considerar las acciones conjuntas, las materialidades y la dialogía intergeneracional para su abordaje.

La conmemoración de los 50 años del golpe de Estado de 1973 en Chile estuvo marcada por el impacto de las violaciones a los derechos humanos perpetradas durante la revuelta social iniciada el 18 de octubre de 2019. Esto ha llevado a considerar como un fracaso el compromiso con el "nunca más" y las garantías de no repetición. En este trabajo se analiza las memorias del pasado reciente y las relaciones establecidas entre la violencia política memorias dictadura y la violencia política del presente. Específicamente, memorias de personas que fueron estudiantes secundarios durante la revuelta y participaron activamente en ella, considerando que ellos han sido protagonistas relevantes de la historia reciente. Se realizaron tres entrevistas cualitativas que posteriormente fueron analizadas desde la perspectiva del análisis crítico del discurso. Los principales resultados fueron organizados en función de las conexiones de la violencia estatal hacia la revuelta con el pasado y con las continuidades y especificidades de la violencia política. Esto permite concluir que en las memorias de estas personas se ha instalado una continuidad de la violencia política de Estado, aunque resignificada desde sus propias experiencias activistas.

The transition to renewable energy systems is critical for addressing global energy security, reducing greenhouse gas emissions, and mitigating climate change. However, the integration of renewable energy sources such as wind, solar, and hydropower into traditional power grids presents a range of technical, operational, and policy challenges. This review explores innovative systems and technologies developed to support the large-scale integration of renewable energy, focusing on smart grids, energy storage solutions, demand-side management, and decentralized energy systems. Additionally, several successful case studies from countries like Denmark, Germany, and Australia are analyzed to highlight best practices and lessons learned in renewable energy integration. Emerging trends such as digitalization, the electrification of transportation, and vehicle-to-grid technology are discussed, alongside the crucial role of government policies and international cooperation in overcoming regulatory barriers and market constraints. The review concludes by outlining future research directions aimed at advancing energy storage, grid modernization, and ensuring a just transition to a low-carbon economy. By leveraging innovative technologies and supportive policies, the integration of renewable energy into global power systems can be accelerated, paving the way for a sustainable and resilient energy future.
