Authors: Saputra Hery , Maulina Suci , Mirunnisa Mirunnisa , Razi Zulfa
Published: June 2023

Mathematics becomes more meaningful when it is relevant to real life and students are more engaged in mathematics learning when it relates to them. Contextual teaching and learning (CTL) is a teaching concept that connects knowledge to real-world situations. The present study aims to investigate the effect of CTL on students’ conceptual understanding of geometry. This experimental study employed a pre-test-post-test control group design. The samples are all eighth-grade students in Junior High School 4, Sakti Pidie, A census sampling technique was used in this study since all members of the population served as samples. The experimental class and the control class were randomly selected from the two available classes. The experimental class was taught geometry using CTL while the control class was taught conventionally. Data were collected from pre-test and post-test that were declared valid. Data analysis was performed using the Kolmogorov-Smirnov test for normality test, the Levene test for homogeneity test, and t-test for the hypothesis testing. The results revealed that students taught using CTL have better conceptual understanding of geometry compared to those who were taught conventionally. It implies that the implementation of contextual teaching and learning (CTL) on geometry learning is effective to promote students’ learning.Keywords: Contextual teaching and learning, conceptual understanding, geometry learning.

EFFICIENCY OF THE SUPERMARKET SECTOR IN THE STATE OF RIO DE JANEIRO BETWEEN 2013 AND 2022
Authors: Nogueira Marcus Vinicius Barcelos
Published: June 2023

The retail sector in Brazil has been making great strides in recent decades, going from revenue of R$224.3 billion to R$611.2 billion in 2021, a result that reflects 7.03% of the Brazilian World Domestic Product (GDP), being one of the most important sectors of the country's economy (ABRAS, 2022). Intense competition has been causing changes in the service offered by the sector, redefining traditional activities in order to attach characteristics of other formats or directing its activities to a more specific niche. This study aims to carry out a historical analysis of efficiency, from 2013 to 2022, of the retail chains listed in the 2022 ABRAS Ranking in the state of Rio de Janeiro, using the DEA (Data Envelopment Analysis) calculation. Through the analysis, it was observed that establishing a single criterion of organizational and operational performance based only on revenue results does not reflect the relative efficiency of each retailer. The results showed that of the 21 retailers presented in the ranking, only eight showed maximum efficiency in the year 2022. Three of these were positioned after the tenth place in the ABRAS 2022 ranking.

Idiosyncratic Deals and Psychological Resilience as Predictors of Employee Engagement among Medical Consultants in Hospitals in Imo State
Authors: Njoku Ethelbert C , Ohazurike Eudora U.
Published: June 2023

Medical consultants play significant role in the lives of people. It is unfortunate that in these roles they play for the health and survival of the citizens, they are not usually appreciated and supported by the various governments. Idiosyncratic deals as negotiated by these consultants in most instances become the real way out of the bad situations and circumstances they find themselves. These consultants and their ability to negotiate work agreements become a veritable means of sustaining the work interest and passion. In this circumstance, employee engagement becomes the anchor that defines the level of commitment and interest in the workplace. Psychological resilience is also another important variable that helps in the realization of this assignment as any organization that does not have the requisite psychological capital may not achieve much. Thus, proper idiosyncratic deal is very important in ensuring that the health of the people are safe guarded and the necessary manpower is retained and not deterred by the insincerity and ineptitude of the government . One hundred and ten people participated in the research and they were drawn from hospitals in Imo state. The research adopted cross sectional survey design. Regression analysis was used in analyzing the data. Of note, the results indicate that the variables predicted employee engagement. The implication confirms the relevance of idiosyncratic deals in sustaining the hospitals in Imo State especially in view of the continued lack of medical infrastructure. Psychological resilience programs should be encouraged and intensified so that the wide knowledge and expertise of medical consultants will not be lost in view of the prevailing poor conditions of work of the medical consultants. Efforts should be made by stakeholders and actors in the health sectors in ensuring maximum attention to issues concerning the manpower management, resources and sustenance.

Published: June 2023

Introdução: A epilepsia é uma desordem neurológica desencadeada pela hiperexcitação, causando crises convulsivas, podendo ter fatores genéticos conhecidos ou desconhecidos. Dentre as formas de epilepsias reflexas temos a mioclônica juvenil, a qual atinge a população jovem com crises mioclônicas e tônico-clônica, sendo geradas pela fotossensibilidade desses pacientes. Objetivo:  estabelecer a relação entre a fotossensibilidade como fator causador da epilepsia mioclônica juvenil, sob a justificativa que essa patologia afeta de forma marcante a vida dos portadores dessa síndrome. Metodologia: Trata-se de uma revisão bibliográfica sistemática, de caráter descritivo e abordagem quantitativa. Resultados: a partir da aplicação da metodologia, foram encontradas17 produções científicas, das quais foram lidas na íntegra e elaborada uma tabela. Discussão: A fotossensibilidade tem íntima relação com o desenvolvimento da epilepsia mioclonica juvenil, devido às respostas fotoparoxísticas, se portar como um fator desencadeante, além da íntima relação da Epilepsia Mioclônica Juvenil (EMJ) com o ciclo sono vigília, despertar e diversos genes que contribuem para seu surgimento e consequentemente redução na qualidade de vida dos portadores.Considerações finais: É notório que para o surgimento da  EMJ, a conectividade funcional alterada das redes de excitação pode contribuir para a compreensão da mioclonia após o despertar, enquanto o aumento da conectividade do tálamo posterior pode explicar a fotossensibilidade.

Transmisión generacional de la empresa familiar
Authors:   , Vidán Peña Luis Javier
Published: June 2023

La sucesión de la empresa familiar es un proceso complejo que integra elementos procedentes de diversas disciplinas jurídicas. Si bien el estudio profundiza en las cuestiones que afectan al derecho civil, tanto al derecho de los contratos como al de familia y sucesorio, es necesario complementar este enfoque jurídico privado con aportaciones procedentes del derecho mercantil, tributario y laboral. Está constatado en la práctica que la opción consistente en la transmisión por partes iguales de la propiedad de la empresa a los descendientes, si bien a priori pudiera parecer la más equitativa, no resulta ser la más adecuada para mantener la armonía familiar y favorecer la conservación de la empresa, pues no permite evaluar y tener en cuenta las capacidades, posibilidades, intereses y necesidades singulares de los posibles sucesores. La decisión idónea es la que responde en cada caso a las singulares circunstancias y coyuntura de cada subsistema empresarial y familiar, y a ella se llega a través de un doble proceso: por un lado, la realización de un análisis riguroso y pormenorizado del marco regulatorio aplicable al proceso de transmisión y sucesión empresarial que permita conocer los instrumentos que favorecen la conservación y transmisión generacional indivisa de la empresa optimizando la satisfacción de todas las demandas implicadas. Y, por otro, la negociación del protocolo familiar, como negocio jurídico contractual que se adapta de forma flexible y singularizada a cada empresa y familia, proceso asistido en su caso por un mediador empresarial en el marco de la regulación estatal y autonómica de este medio autocompositivo y preventivo de conflictos. A tal fin se aborda el estudio del concepto y naturaleza, contenido y eficacia del protocolo familiar como contrato marco cuyo clausulado articula jurídicamente la planificación de los aspectos relativos a la transmisión y conservación de la compañía. A partir de ahí, se profundiza en los instrumentos que ofrece el ordenamiento jurídico para ejecutar y dotar de eficacia jurídica a los consensos recogidos en el protocolo familiar, analizando los aspectos que se deben tener en cuenta desde los ámbitos civil, fiscal y de la seguridad social. Se pretende de este modo elaborar una propuesta transversal, interdisciplinar y práctica que dé respuesta a los interrogantes y dificultades que encuentra la empresa familiar para trascender generacionalmente.

Authors: Archanjo Rocha Martins Islane , Douglas de Paula Costa Maycon
Published: June 2023

A Lei dos crimes hediondos passou por mudanças recentemente. Notando-se que as retificações acontecem esporadicamente, as alterações inseridas no rol da hediondez têm como objetivo combater a criminalidade e, de forma diferenciada, ressocializar o infrator. Com base nessa premissa, foi-se necessário desenvolver um estudo que demonstrasse os reflexos do instituto Direito Penal do inimigo, o qual consagra o tratamento diferenciado àquele que descumpre o contrato social. O objetivo geral é verificar os reflexos do Direito Penal do inimigo na Lei dos crimes hediondos para, assim, desenvolver o estudar os institutos e verificar se há (in)compatibilidade no ordenamento jurídico. Em relação à metodologia empregada, utilizou-se de pesquisa bibliográfica com a finalidade de proporcionar melhores informações sobre o tema. O trabalho conclui-se demonstrando que o Direito Penal do inimigo possui reflexos na Lei dos crimes hediondos, onde há desproporcionalidade das penas, o endurecimento da execução penal e a restrição das garantias penais e processuais.
Efetivação dos direitos das vítimas criminais pelo controle de convencionalidade
Authors: Dos Santos Vedoatto Karina Ribeiro , Flores Andrea , Do Amaral Rabelo Luciana
Published: June 2023

O artigo, por meio do método indutivo e de pesquisas bibliográficas e documentais, busca identificar os direitos fundamentais das vítimas, examinar o fenômeno da vitimização e analisar o controle de convencionalidade como um meio para efetivar tais direitos, a partir da análise das normativas existentes e dos erros e omissões do Brasil, expressamente reconhecidos nas condenações da Corte IDH. As pesquisas apontaram que com as atrocidades da 2ª Guerra Mundial iniciou-se a busca pelo reconhecimento dos direitos das vítimas, com a criação de normas internacionais descrevendo-lhes diversos direitos. Contudo, mesmo tendo previsão normativa, na prática, estes direitos não são efetivados pelo Estado Brasileiro e encontra-se muito aquém do desejável pelo Sistema Americano de proteção dos direitos humanos. Assim, as pesquisas apontam o exercício do controle de convencionalidade, pelas autoridades e órgãos competentes, como um caminho rápido e eficaz para a efetivação dos direitos fundamentais das vítimas no ordenamento jurídico brasileiro.

Published: June 2023

O trabalho possui como objetivo geral a análise da responsabilidade dos indivíduos acerca do uso dos direitos da personalidade. Trabalha-se com a hipótese de colisão entre direitos da personalidade, de modo a indicar como exemplo a oposição entre liberdade de expressão e honra. O texto aborda a evolução histórica dos direitos fundamentais e os novos direitos, necessários para a efetividade da dignidade da pessoa humana. Reflete-se sobre a colisão dos direitos, tendo como forma de solução deste conflito a utilização do postulado da proporcionalidade. Para tanto, a pesquisa se vale do método hipotético-dedutivo, tendo a pesquisa bibliográfica como procedimento metodológico. Neste contexto, identifica-se a ausência de solução específica, devendo ser observado as particularidades de cada caso, sopesando as características para a preservação de ambos os direitos. Ao final, destaca-se que a pessoa é responsável pela maneira como faz uso de seus direitos e que responderá pelas extrapolações que cometer.

"With regards to storing thermal energy, latent heat storage are the matter of growing attention over the past years due to their straightforward design, affordable production and maintenance costs, as well as universal applicability. The phase-change materials (PCM) are well-known for their widespread use in aforementioned systems primarily because of their high thermal storage density. Many studies concerning analysing and optimising the design of latent heat storage systems (LHHS) have been carried out in the last years. In relatively recent researches, different research teams have investigated different types of LHHS, using mathematical models of different levels of complexity. The wide variety of different approaches to the mathematical modeling (including different methods, algorithms and applications from different field of pure and applied research) sometimes make it challenging to choose and implement a proper system of equations and criteria without excessive complicacies. This very paper describes and elaborates on the system of equations that can and will be applied to the mathematical modeling of charging/recharging process in PCM-based LHHS for commercial vehicles. After a brief review of previous models, author presents the model and asses its accuracy and possibilities for further development and exploration. "

"Проектирование защиты от шума транспорта автомобильных дорог заключается в разработке шумозащитных мероприятий с учетом параметров дорожного движения, технических параметров дорог, природных условий местности, а также реального акустического загрязнения и характеристик жилой застройки. На стадии проекта закладываются основы защиты от шума на двадцатилетнюю перспективу, поэтому решение вопросов, связанных с обеспечением норм акустической безопасности является важным. В работе рассматривается одна из проблем практики проектирования участка реконструируемой автомобильной дороги с развязкой в двух уровнях. Взят конкретный пример выполнения технического задания на проектирование защиты от шума участка реконструируемой автомобильной дороги непрерывного движения с транспортной развязкой в двух уровнях Проведены акустические расчеты, в которых источниками шума являются элементы автомобильной дороги с разной интенсивностью движения автотранспорта. Определены расчетные точки в жилой застройке, рассчитано требуемое снижение эквивалентных уровней звука для достижения акустических нормативов. На основе этих расчетов спроектированы защитные сооружения – акустические экраны, которые являются проектным решением. Аналогично сделаны дополнительные акустические расчеты, в которых источниками шума являются элементы улично-дорожной сети, расположенные на территории проектируемого земельного участка, но не входящие в техническое задание на проектирование – съезды с реконструируемой автомобильной дороги и магистральная улица регулируемого движения, проходящая под развязкой. Установлено, что для соблюдения акустических нормативов в зоне жилой застройки необходимо рассчитывать акустическое воздействие всех элементов улично-дорожной сети проектируемого участка территории, а не только элементов реконструируемого объекта, чем обычно ограничивается техническое задание на проектирование.

"ПОЛУЧЕНИЕ ОЛОВА ИЗ РАСТВОРОВ В ДИСПЕРСНОЙ ФОРМЕ "

"Цементационное извлечение металлов из растворов широко применяется в гидрометаллургии. Известно, что на процесс цементации значительное влияние оказывает кристаллизующийся на поверхности металла – цементатора слой (осадок) цементируемого металла. Компактный слой изолирует поверхность металла – цементатора от раствора, и реакция цементации сильно замедляется или вовсе прекращается. Напротив, порошкообразный (дисперсный) осадок не только не замедляет цементацию, но в ряде случаев даже увеличивает скорость процесса, чему способствует развитая поверхность катодных участков, на которых восстанавливаются ионы цементируемого металла. Поскольку алюминий менее дорогостоящий металл, чем цинк, а сернокислое олово является побочным продуктом электролитического рафинирования некоторых металлов, представляет практический интерес более подробно исследовать процесс цементационного восстановления олова из раствора SnSO4. В данной работе экспериментально установлено, что для реализации процесса цементационного извлечения олова в дисперсной форме из растворов SnSO4 цементирующий металл алюминий необходимо активировать ионами хлора. Результаты поляризационных измерений электродных процессов контактной гальванопары Al-Sn согласуются с результатами планированных опытов по получению оловянного порошка цементации олова алюминием из растворов SnSO4 с учетом влияния конкурирующего процесса выделения водорода."

"В данной статье представлена возможность замены природного сырья композиционным вяжущим веществом в качестве наполнителя при производстве строительных материалов, для снижения себестоимости строительных материалов и конструкций. Добыча минерального сырья занимает в экономике любой страны огромную часть, при переработке его в конечный продукт используются лишь небольшое количество. Основная часть его переходит в отходы, что загрязняет окружающую среду. Проблема использование отходов является самой насущной на данный момент времени, которая требует дополнительных капиталовложений для создания дополнительного звена в технологическом процессе для переработки отходов в конечный продукт конкурентоспособный на рынке. Производство новых строительных материалов постоянно идет вперед заменяя природный материал на искусственный, современное материаловедение является областью для изучения многих ученых мира. В процессе измельчения гипса и шлака происходит повышение активности вещества вследствие чего усиливается протекание гидротационных процессов, образуя гидроалюминат и гидросиликаты кальция. При этом происходит двухконтурная грануляция гипса, которая увеличивается при соединении гидросиликата. Повышение количества полуводного гипса до 20 % и давления прессования до 50 МПа способствует повышению прочности изделий из сульфогипса до 7–9 МПа. Также добавка глениума несколько снижает прочность, но способствует повышению водостойкости материала. "
Los contratos hidrosociales en el acceso al agua en barrios populares: Articulaciones entre actores barriales y el gobierno local del Partido de General Pueyrredón.

Published: June 2023

La meta de lograr el 100% de cobertura de agua gestionada de manera segura para el año 2030, establecida por la agenda de Desarrollo Sostenible, presenta desafíos significativos para la Argentina, donde los barrios populares representan casi el 65% de las áreas urbanas no servidas. Esto lleva a que la provisión de servicios dependa principalmente de los esfuerzos y estrategias de la población, que construye infraestructura por fuera de los mecanismos formales (y mercantiles). En este trabajo se analizan las estrategias de acceso al agua en los barrios populares, a partir de considerarlas como "contratos hidrosociales", destacando el rol que el conflicto, la tensión y las alianzas entre los grupos sociales, las autoridades locales y los actores de la sociedad civil tienen. Los resultados buscan caracterizar “cómo” se construyen y funcionan estas redes de infraestructura en y señalar algunas particularidades de la participación de los gobiernos locales en esta articulación.
