Analysis of PAPR reduction of optical-OTFS for 256-QAM using companding and clipping–filtering algorithms
Authors: Kumar Arun , Chakravarty Sumit , Nanthaamornphong Aziz
Published: January 2024

The article presents an investigation into Peak-to-Average Power Ratio (PAPR) reduction techniques in Optical Orthogonal Time Frequency Space (O-OTFS) modulation. Focusing on clipping and filtering as well as companding methods, the study explores their efficacy in mitigating PAPR challenges inherent in O-OTFS waveforms. The research evaluates the impact of these techniques on signal quality, particularly in the context of a Rician channel. Clipping and filtering (C&F) are examined for their ability to control amplitude peaks, while companding is analyzed for its role in optimizing dynamic range. The study conducts a comprehensive analysis of Bit Error Rate (BER) and power spectrum density (PSD) under varying conditions, shedding light on how these methods influence the reliability and robustness of OTFS communication. The investigation considers the interplay of these PAPR reduction methods with the unique characteristics of the Rician and Rayleigh channel, which includes a dominant line-of-sight component. The findings contribute valuable insights into designing efficient OTFS modulation systems for real-world scenarios. Ultimately, this research aims to provide a deeper understanding of PAPR reduction strategies in OTFS, offering guidance for optimizing signal processing techniques in communication systems where mitigating PAPR is crucial for achieving high performance and reliable data transmission. It is noted that the proposed C&F and companding algorithms outperform the conventional methods and achieved a PAPR gain of 1–3 dB and BER gain of 10.6–2 dB.

Manipulating the spontaneous emission rate of fluorophores is vital in creating bright incoherent illumination for optical sensing and imaging, as well as fast single-photon sources for quantum technology applications. This can be done via increasing the Purcell effect by using non-monolithic optical nanocavities; however, achieving the desired performance is challenging due to difficulties in fabrication, precise positioning, and frequency tuning of cavity-emitter coupling. Here, we demonstrate a simple approach to achieve a wavelength-dependent photoluminescence (PL) lifetime modification using monolithic organic molecular aggregates films. These single monolithic organic films are designed to have a Lorentzian dispersion, including epsilon-near-zero (ENZ) and epsilon-near-pole (ENP) spectral regions with increased and decreased photonic density of states, respectively. This dispersion leads to enhanced and depressed PL decay rates at different wavelengths. Both time-resolved photoluminescence (TRPL) and fluorescence lifetime imaging microscopy (FLIM) measurements are implemented to verify the validity of this approach. This approach offers a promising way to design dual-functional optical sources for a variety of applications, including bioimaging, sensing, data communications, and quantum photonics applications.

Published: January 2024

The impact of noise can arise from the operation of a mineral ore processing plant in the mining industry, such as PT Freeport Indonesia. The use of advanced technology in modern industry, like SAG#3, has increased production productivity but can also lead to noise emission issues that may endanger workers’ health. This research aims to project the impact of noise in the workplace at a new mineral ore processing plant using dynamic system analysis. Noise sampling was conducted using a sound level meter instrument following SNI 7231:2009. After data collection, dynamic system analysis was performed using Vensim Pro software, involving steps such as causal loop design, stock flow diagram formation, and model verification testing. The analysis results indicate that the noise level exceeds the permissible exposure limit, measuring at 85 dBA. Therefore, the implementation of a Hearing Conservation Program (HCP), personal protective equipment (PPE) policies, and periodic noise control policy evaluation are crucial steps in reducing the impact of noise on employees. This study highlights the need for concrete actions by the company, such as improving the effectiveness of the HCP, enforcing stricter PPE policies, and conducting regular evaluations. Consequently, the company can create a safer work environment and reduce the health risks associated with noise exposure in the workplace.

Published: January 2024

A era da Indústria 4.0 é marcada por automação avançada, análise de dados em larga escala (Big Data) e Internet das Coisas, com uma redução significativa da intervenção humana nos processos de manufatura. Essa transformação impacta diretamente na área de planejamento de projetos, exigindo adaptações e atualizações para lidar com as mais recentes tecnologias e sistemas interconectados. Embora a literatura internacional forneça uma base sólida sobre a Indústria 4.0, a aplicação prática e as particularidades desse movimento em empresas brasileiras ainda carecem de uma análise detalhada. Este estudo visa preencher essa lacuna ao investigar como uma empresa local se adapta às demandas e desafios da Indústria 4.0. Este estudo tem como principal objetivo analisar o sistema de planejamento de projetos e o gerenciamento de riscos tecnológicos, com o intuito de oferecer maior clareza para empresas que buscam implementar a Indústria 4.0. Especificamente, buscamos identificar as práticas, desafios e benefícios da virtualização de dados, bem como a capacidade de decisão autônoma do software de planejamento e o papel fundamental do software MRP (Planejamento de recursos para Fabricação) na consulta de dados. Utilizamos uma abordagem que combina revisão da literatura internacional com um estudo de caso de uma multinacional brasileira. Realizamos entrevistas com profissionais da empresa para obter informações valiosas sobre suas práticas e desafios relacionados ao planejamento de projetos e ao gerenciamento de riscos tecnológicos. Nossas descobertas revelam que a empresa estudada possui uma sólida compreensão das práticas necessárias para a virtualização de dados, que é essencial na Indústria 4.0. Além disso, o software de planejamento permite a tomada de decisões autônomas, otimizando a eficiência e a confiabilidade dos relatórios. O software MRP desempenha um papel crítico na consulta de dados e na capacidade de negociação. Este estudo destaca a importância da adaptação das empresas aos desafios da Indústria 4.0 e a capacidade de gerenciar com eficácia o planejamento de projetos e os riscos tecnológicos. A hierarquia na limitação de acesso ao sistema demonstra ser um fator crucial na segurança de informações, particularmente no que diz respeito à proteção do patrimônio intelectual. A Indústria 4.0 traz novos desafios e oportunidades, e as empresas que buscam aderir a esse movimento devem estar preparadas para enfrentá-los.

Authors: Ribeiro Martins Wellington
Published: January 2024

O biofertilizante é uma alternativa para o destino da grande produção de esterco proveniente das atividades pecuárias no Brasil, evitando que ele se torne uma fonte de poluição para o meio ambiente e uma alternativa de fertilizante de baixo custo para produtores em áreas com solos de baixa fertilidade. O objetivo deste estudo foi avaliar a aplicação de doses de biofertilizante produzido a partir de esterco bovino preparado com e sem agitação, sobre a produção e composição nutricional de Urochloa brizantha cv. Marandu. O experimento foi conduzido na Casa de Vegetação, localizada no campus II da Universidade do Oeste Paulista, município de Presidente Prudente/SP. Foi instalado um delineamento inteiramente casualizado, com quatro doses de biofertilizante (0, 50, 100 e 150 m³/ha) em sete repetições. As seguintes avaliações foram realizadas: altura da planta, massa aérea, matéria seca, matéria mineral, proteína bruta, nutrientes totais digestíveis e fibra em detergente neutro e ácido. Os resultados obtidos indicaram uma resposta linear crescente para todas as variáveis avaliadas no experimento. A massa seca da parte aérea com a aplicação de 150 m³ mostrou um crescimento duas vezes maior quando comparada à dose 0. As variáveis bromatológicas foram influenciadas pela adição do biofertilizante, permitindo aumentos da ordem de 15% nos teores de proteína bruta e matéria mineral. Assim, o biofertilizante preparado sem agitação pode proporcionar uma melhor redução de custos pela facilidade de preparação e aplicação para o pequeno produtor.
A Study on Failure Rate, Reliability, and Collection Efficiency Trend of Bag Filters in a Cement Plant
Authors: Jena Madhab C. , Mishra Sarat K. , Moharana Himanshu S.
Published: January 2024

This thesis presents a comprehensive study on the failure rate, reliability, and collection efficiency trends of bag filters in a cement plant over 15 years. Bag filters are vital pollution control equipment used in various industries, including cement plants, to maintain environmental compliance. Understanding their performance and failure patterns is crucial to ensure efficient and reliable operation while adhering to stringent pollution control standards. The research findings reveal that the failure rate trend of bag filters closely follows the bathtub curve, with an initial high failure rate, a period of lower failures, and a subsequent increase in failures as the equipment nears the end of its life cycle. Reliability trends align with Madhab's Hat curve, exhibiting higher reliability during the first 10 to 12 years of operation, followed by a decline in reliability. The collection efficiency of bag filters declines as the equipment ages, with the efficiency decreasing from 99.998% in the early years to 95.05% in the 15th year. This emphasizes the importance of maintenance and retrofitting for older dust collection equipment to maintain high collection efficiency. The study concludes that the typical life span of bag filters ranges from 10 to 15 years, after which major maintenance interventions are necessary to minimize failure rates. The research provides valuable insights for maintenance engineers, design engineers, and reliability engineers, enabling them to improve the performance of pollution control equipment, such as bag filters, reverse air bag houses (RABH), and electrostatic precipitators (ESP), to meet the pollution control standards set by regulatory authorities.

Authors: Kurnia Chyntia Putriasni , Wasilah Fajar , Lismayanti Leni
Published: January 2024

Mild, moderate, severe, and critical COVID-19 are associated with hyperinflammation. The CRP and ferritin are acute phase proteins that marks incidence of inflammation and used as the paramaters of hyperinflammation. This study aimed to determine the validity of CRP and ferritin level examination in moderate and severe COVID-19 since the time of admission. This was a cross-sectional analytical retrospective study with on moderate and severe COVID-19 patients admitted to Dr. Hasan Sadikin General Hospital Bandung, Indonesia, during the period of March 2020 to December 2020. The CRP and ferritin levels were obtained since the beginning of admission to the fourth day since admission on patients without any history of anemia. Subjects in this study were divided into moderate and severe COVID-19 groups based on the 3rd edition of COVID-19 Prevention and Control Guideline issued by the Ministry of Health Republic of Indonesia. Each group consisted of 30 subjects. The cut-off value was 7.65 mg/dL (AUC 0.698) for CRP and 963.1 mcg/L (AUC 0.938) for ferritin. The validity of ferritin vs CRP were reflected respectively as follows:  93.3% vs 76.7% sensitivity; 80.0% vs 63.3% specificity; 82.4% vs 67.6% PPV; and 92.3% vs 73.1% NPV. The validity of ferritin was proven to be superior as it  significantly increases since day one, persisted longer and reaches its peak on  the16th day. Meanwhile, CRP increases within 6-8 hours and reaches its peak within 48 hours after inflammation, then declines soon afterwards.

Published: January 2024

Infant birth weight is an important indicator of survival, growth potential, and developmental capacity. Maternal health plays an important role in determining the well-being of newborns. A complicated pregnancy, inclusive of conditions such as preeclampsia, elevates the risk of giving birth to a low birth weight (LBW) baby. This study aimed to compare the impact of severe preeclampsia on the incidence of LBW babies in Dr. Dradjat Prawiranegara General Hospital Serang, Indonesia. This case-control analysis included 148 parturients recruited randomly from June to October 2022. Logistic regression was used as the analytical tool, with P=0.000 considered as demonstrating a significant association. The incidence rates of LBW and severe preeclampsia in 2018 were 19.84% and 14.15%, respectively. The case group recorded LBW within the weight range of 1,000-2,450 g, with 38% of them were Small for Gestation Age (SGA), while 50% and 12% were Appropriate for Gestational Age (AGA), and Large for Gestational Age (LGA), respectively. In contrast, the control group, with birth weights ranging from 2,600-4,500 g, 13.50% were SGA, while 77% and 9.50% were AGA and LGA, respectively. Parity was a confounding factor influencing the incidence of LBW, while maternal age did not present a significant correlation. Pregnancies with severe preeclampsia were found to have a 29-fold increased likelihood of delivering LBW babies compared to the control group when controlling for parity (P=0.000, CI 95%). Hence, women with severe preeclampsia pregnancies have a higher risk for delivering LBW babies of 29 times higher than the control.
Pin-less moisture meter comparison to pin-type moisture meters in gypsum board and the effect of backing materials on pin-less readings
Authors: Wilkie Alexander D , Venz Lauren , Letters Sarah , Tersakian Anayis
Published: January 2024

Moisture meters are invaluable tools used in the building inspection industry. Little comparative data is available for pin-type (resistance) verse pin-less (capacitance) moisture meters. There is also a lack of data for pin-less moisture meters in regard to the effect of backing materials on the readings obtained. We present data comparing four common moisture meters used in building inspections and investigate the effect of backing materials on readings in gypsum board. Moisture readings taken by the Trotec and CEM meters correlated well with moisture readings taken with resistance measurements and comparison to gravimetric moisture content. The moisture meters varied in their responses to backing materials with the Trotec showing the smallest effects and the CEM showing the largest. Different moisture meters may be useful in different applications, and inspectors must carefully consider results from pin-less readings to obtain relevant data of moisture investigations.
A comparative analysis of hungarian and american medical liability: examining medical malpractice in justice
Authors: Petra Shakibapoor Amanda
Published: January 2024

In recent years, medical liability and medical malpractice lawsuits have gained particular importance in the field of law. They have a great influence on trust in medicine and the entire health care system, so their knowledge and understanding are indispensable. The purpose of my essay is to present and compare the Hungarian and American medical liability systems with a particular focus on medical malpractice and its impact on the pursuit of justice. I will light out that the Hungarian and the American legal frameworks concerning medical liability differ in several aspects, including the burden of proof, statutes of limitations, damage caps, and compensation mechanisms. By comparing and contrasting these two distinct contexts, i would like to show the strengths and weaknesses of each system and identify potential areas for improvement. Potential improvements may include clearer guidelines for determining medical malpractice, establishing specialist medical malpractice courts, incentivizing early settlement, and evaluating the need for limitation on damages. In conclusion, this essay presents an analysis of the medical liability systems in Hungary and the United States, focusing on medical malpractice. Through a comparative examination I would like to point out the need for reform to ensure justice for patients while protecting the healthcare profession. By learning from one another, both countries have the potential to enhance their respective medical liability systems and provide better avenues for resolving medical malpractice claims.

Background. Glioblastoma (GBM) is the most frequent primary malignant CNS tumor. Deficient mismatch repair (dMMR) is associated with better prognosis and is a biomarker for immunotherapy. Evaluation of MMR by immunohistochemistry (IHC) is accessible, cost effective, sensitive, and specific. Aim. Our objective was to investigate MMR proteins in adult GBM patients. Materials and Methods. We retrospectively analyzed 68 GBM samples to evaluate the proficiency of MMR genes expression assessed by IHC. Clinicopathologic and molecular features were compared in proficient (pMMR) or dMMR. Results. 10 (14.7%) samples showed dMMR, and the most frequent was MSH6 (100%) followed by MSH2, PMS2, and MLH1. We observed heterogeneous expression of dMMR in 5 GBMs. The median overall survival did not differ between pMMR (19.8 months; 0.2—30) and dMMR (16.9 months; 6.4—27.5) (p = 0.31). We observed a significantly higher overall survival associated with gross total resection compared to subtotal resection or biopsy (30.7 vs. 13.6 months, p = 0.02) and MGMT methylated status (29.6 vs. 19.8 months, p = 0.049). At the analysis time, 10 patients were still alive, all in the pMMR group. Conclusions. Our data demonstrated dMMR phenotype assessed by IHC in an expressive portion of GBM patients, however without significant impact on overall survival.

Background. In the last decades, the incidence of breast cancer (BCa) in young women has been increasing steadily. The quantitative indicators of expression of collagen, which play important role in stromal microenvironment, and their association with the age and survival rates of BCa patients have not been yet definitively clarified. Aim. To investigate the relationship between the COL1A1 gene expression at the mRNA and protein levels in BCa tissue and the clinicopatological features and survival rates of BCa patients of different age groups. Materials and Methods. The study was conducted on the clinical material of 50 patients with stage I—III BCa. COL1A1 gene expression at the mRNA and protein levels in BCa tissue were studied using the real-time PCR and immunohistochemical methods, as well as the bioinformatic analysis (UALCAN and Kaplan — Meier Plotter databases). Results. The bioinformatic analysis showed that BCa tissue is characterized by 6.0 times (p < 0.05) higher level of COL1A1 mRNA compared to normal breast tissue. The correlation of COL1A1 expression at the mRNA and protein levels with the molecular subtype of neoplasms was demonstrated. According to Kaplan — Meier Plotter database, a low level of expression of COL1A1 protein level in BCa tissue is associated with lower rates of relapse-free survival of patients. The ex vivo study of the clinical material revealed a decrease in COL1A1 protein expression in tumor tissue of young patients with BCa of T3 category (p < 0.0374), low differentiation grade (p < 0.0163) and basal molecular subtype (p < 0.0001). A correlation between the expression of COL1A1 at the mRNA and protein levels and the expression status of estrogen receptors (p < 0.0001) and progesterone receptors (p < 0.0040) was established. The relapse-free 3-year survival rate of young BCa patients is significantly lower in the presence of a low COL1A1 optical density index in the tumor tissue. Conclusions. The identified relationship between COL1A1 expression and such indicators of BCa malignancy as tumor size, differentiation grade, molecular subtype, receptor status, and the recurrencefree survival of patients indicates the prospects of its use to predict the aggressiveness of the BCa course in young patients.
Morfología urbana, actores y elementos arquitectónicos del programa de construcción Gran Misión Vivienda Venezuela
Authors: WILSON Yaneira
Published: January 2024

Desde Hugo Chávez, en 1999, hasta Nicolás Maduro, Venezuela ha estado inmersa en una serie de reformas conocidas como la Revolución Bolivariana. En 2023, el Gobierno mantiene un discurso performativo que dicta la finalización de los 5 millones de viviendas que deben construirse para 2025 y propone mostrar esta hazaña como el legado que el “Comandante Eterno”, Hugo Chávez Frías, deja al pueblo venezolano. En 2003, las antiguas políticas públicas del país fueron desmanteladas en favor de nuevos planes, que recibieron el nombre de misiones, en las que se desarrollan programas de lucha contra la pobreza, en temas de agricultura, vivienda, educación y salud, con el fin de responder a las emergencias sociales fuera del marco institucional y suplir la lentitud administrativa y la falta de capacidad de respuesta de los gobiernos anteriores. La hipótesis de este artículo es que el actual paisaje urbano de la Gran Misión Vivienda Venezuela (GMVV) se ha convertido en un reflejo de la crisis política, social y económica que atraviesa el país. Por lo tanto, se plantean las siguientes preguntas ¿Cómo se inserta esta política habitacional en el territorio nacional? ¿Cómo viven y perciben los habitantes estos nuevos edificios y espacios construidos en el marco de la GMVV? ¿Cómo describen y se apropian los habitantes de estos espacios? Para dar una respuesta, se trabajó con información obtenida durante visitas de campo entre 2015 y 2020, a través de observación participativa, análisis y extractos de entrevistas, además de referencias científicas que complementan el análisis.
Parque urbano Tlapacoyan: un espacio invisible en la zona sur de la ciudad de Puebla
Authors: Vega Ramírez Apud Eric , Nava Ramírez Rosario
Published: January 2024

De tener una adecuada planificación, las colonias populares y medias como La Luna, La Concepción, Buenos Aires, etc., ubicadas en la zona sur de la ciudad de Puebla contarían con vías de comunicación accesibles y espacios públicos de alta calidad. Sin embargo, en la actualidad, estas áreas forman una zona marginada y están experimentando un proceso de degradación ambiental debido a la apropiación irregular del territorio. Este proceso amenaza la posibilidad de que el sector sur de la ciudad cuente con una extensión significativa de áreas verdes, que bridarían múltiples beneficios ambientales y sociales a la población adyacente, e incluso a nivel metropolitano.
La falta de acciones por parte del gobierno para imponer orden y hacer cumplir los instrumentos de planeación y legislación ha traído consigo la deformación del espacio público. La expansión de la ciudad se ha dejado en manos del sector inmobiliario y de los ejidatarios que buscan obtener ganancias a través de la venta de las tierras que el propio Estado les otorgó. Esas tierras ahora forman parte de un mercado que no busca un entorno ambiental saludable, bienestar social, calidad de los espacios públicos ni la habitabilidad, sino que se centra en el aspecto económico del desarrollo.

Road infrastructure has caused severe impacts on the environment and wildlife. Understanding and mitigating these effects are essential conservation measures.   This study aimed to evaluate wildlife mortality due to animal-vehicle collisions along an 80-km stretch of the Tapir Rocha Highway (RS–040). The field inventory was carried out between August 2015 and March 2019. Once a week, two observers drove along the highway at an average speed of 40 km/h and all the vertebrate roadkill spotted from the car were assessed to record the species, carcass condition, and the roadkill locations along the road. In total, 2,371 dead animals were recorded and categorized into 137 species. The most affected classes were mammals (n = 1,223), and birds (n = 704). The most affected wild species were white-eared opossums (Didelphis albiventris, n = 559), black-and-white tegus (Salvator merianae, n = 129), and coypus (Myocastor coypus, n = 102). Carcass exposure assessments indicated that many (n = 637) of the animal deaths occurred the night before our arrival, which may suggest that nocturnal species were among the most vulnerable to mortality. Roadkill sighting peaked in the spring (34%) and summer (25%), probably due to reproductive activity and juvenile dispersal. Evident seasonal variations included a 50% reduction in reptile roadkill rates in autumn-winter compared to spring-summer, and a 20-percentage-point increase in the number of mammal road deaths in the winter. The reduced activity that reptiles display at low temperatures, and seasonal changes in carnivore food habits may explain these respective findings. While most of the animal victims of roadkill were common and widely distributed species with abundant populations, decreasing abundance of these species is a growing conservation concern.
Towards Institutionalised TVET Research in Costa Rica–Empirical Analysis on Status, Needs, and Challenges
Authors: Rommel Irina , Angles Enrique , Frommberger Dietmar
Published: January 2024

Technical Vocational Education and Training (TVET) in Costa Rica is considered as an important alternative for the insertion of the young population into the labor market. However, despite the increasing importance of TVET there is a lack of institutionalized research activities, so that research efforts on TVET mainly remain in the background. The aim of this paper is to present and examine the level of institutionalization of TVET research in Costa Rica and the associated needs, challenges, and demands. Therefore, qualitative research, with an exploratory scope, was conducted between December 2022 and June 2023, for which a literature review on TVET research and semi-structured interviews with sixteen experts were carried out. The results revealed, that from 2020 to date, there has been an increase in the number of research activities in TVET and in the number of publications in Costa Rican journals. Nevertheless, TVET institutions in Costa Rica show low capacities in terms of personnel and financial resources to conduct TVET research. The main conclusion is that the level of institutionalization of TVET Research in Costa Rica is in its infancy, but has potential for growth, for which it is necessary to establish public TVET policies that include TVET research.
Prejuicio en la campaña antimodernista del periódico A Gazeta de São Paulo (1921-1922)
Authors: Ortiz Vergara Jorge Israel
Published: January 2024

El objetivo del presente artículo es la verificación de la existencia y el análisis del prejuicio en la campaña del periódico A Gazeta de São Paulo contra el movimiento modernista entre 1921 y 1922. Los textos fueron encontrados gracias a una investigación con palabras clave en la Hemeroteca Digital de la Biblioteca Nacional de Brasil. Peyorativamente, se determinó que A Gazeta produjo distintos tipos de textos periodísticos y divulgó contenido capacitista, homofóbico, misógino y racista. Además, los términos musicales se relacionaron despectivamente con la cultura negra, indígena y popular. Durante la campaña, varios artistas fueron mencionados, incluyendo el modernista Mário de Andrade, quien fue ampliamente criticado y perjuriado. Por lo tanto, se concluyó que el autor de este informe realizó análisis de textos con prejuicio explícito y registró consideraciones sobre el carácter y algunos efectos del prejuicio. El análisis de la “reacción antifuturista” revela la temprana recepción de Andrade y del movimiento modernista, el uso del prejuicio en el debate artístico y la construcción social del prejuicio.
Somalilandia: fraternidad en clave de mujer. Resistencia rimada por la paz (1991-1996)
Authors: Mata Carnevali María Gabriela
Published: January 2024

En la vena pluralista postmoderna, que abre paso a nuevas formas de leer los textos y la historia, el bicentenario de la Revolución Francesa (1789) despertó un renovado interés por su triada principista en general, pero sobre todo por la fraternidad en tanto categoría política. Desde los primeros estudios llevados adelante en Europa y América Latina, quedó clara su importancia para la construcción de la paz y la evolución de las democracias. En este artículo, se aborda la fraternidad en el marco de la conformación y consolidación de Somalilandia como un estado independiente (1991-1996), destacando su relevancia para el debate sobre resistencia civil y las formas de lucha no violenta. Debido al indiscutido protagonismo de las mujeres, sobre todo las poetas, es posible subrayar la importancia y particularidades de la participación femenina en los movimientos de resistencia y la relevancia de las artes como medio de lucha.
La actividad coral amateur: beneficios para la salud y el bienestar en personas adultas. Una revisión crítica del estado del arte
Authors: Lorenzo de Reizábal Margarita
Published: January 2024

Existe un corpus de investigación, aún incipiente pero prometedor, en el ámbito de las actividades grupales vocales, y su impacto en la salud y el bienestar de las personas, que se sintetiza en este trabajo. En este, se aportan las evidencias más relevantes y ponen el foco en los coros amateurs de personas adultas. Se hace especial énfasis en los mecanismos generativos que relacionan el canto coral con la salud y el bienestar en las personas adultas desde cuatro perspectivas: emocional, mental, social y fisiológica. Se argumenta que un grupo coral funciona como un equipo, que existen diferencias entre hombres y mujeres en las respuestas emocionales a las actividades corales, y se aborda el canto coral amateur como una actividad de ocio formativo para la que se precisa aplicar estrategias didácticas adecuadas a un colectivo de adultos desde un enfoque andragógico. Finalmente, se presenta una reflexión crítica sobre las fortalezas y debilidades de las investigaciones realizadas hasta el momento, como la falta de sinergias entre los estudios realizados, cierto sesgo positivista que elude visualizar y analizar también los contras de la práctica coral, y la falta de indicadores musicales, de liderazgo y relacionales que podrían explicar parte de los resultados obtenidos e, incluso, limitarlos.

El trabajo utiliza métodos de investigación cualitativa de análisis de contenido y descriptivo para analizar las notas periodísticas obtenidas de las fuentes primarias, las cuales fueron las ediciones publicadas que se encuentran en el Sistema Nacional de Bibliotecas de Costa Rica. Los resultados muestran que la mayoría de las notas de prensa son de contenido comercial, pero también una parte importante de contenido histórico. En menos cantidad, se encuentran las de contenido educativo, deportivo, social, comunitario y literario. Se concluye del análisis que, de acuerdo con la revista, la comunidad china en Costa Rica ha contribuido con el desarrollo de las comunidades en donde se establecen.
El territorio posmoderno: un acercamiento normativo a los procesos de producción, organización y orientación del espacio
Authors: Puentes Sánchez Juan Camilo
Published: January 2024

La posmodernidad no se circunscribe únicamente a las profundas transformaciones de las estructuras sociales o culturales originadas en el último siglo, sino también a las de ciertas estructuras políticas tradicionales como el Estado y sus elementos constitutivos. A través de un enfoque normativo, el presente ensayo analiza los cambios del territorio ocasionados por la hegemonía de las fuerzas posmodernas representadas en el capitalismo posindustrializado, la globalización, y la revolución informática y comunicativa. Los resultados preliminares explican dichas dinámicas transformativas a partir de tres procesos interrelacionados: la producción, la organización y la orientación del espacio. En cada uno de esos niveles, el territorio deja de ser un objeto político por naturaleza, capaz de cumplir sus funciones congregacionales en torno a un ideal político comunitario para convertirse, en cambio, en una unidad política que privilegia otro tipo de intereses, ante todo, de índole económica.

O compliance na educação profissional e tecnológica: uma análise sobre a importância da aplicação na educação profissional e tecnológica
Authors: Dias de Azevedo Sérgio , Lima Sanches Keila
Published: January 2024

Os Institutos Federais de Educação Ciência e Tecnologia possuem projetos pedagógicos organizados visando a educação além do espaço formal, proporcionando experiências que exerçam uma função educadora na construção de uma sociedade solidária entre indivíduos, povos e nações. Por isso, é de grande importância que seus funcionários estejam atentos aos princípios éticos, já que uma instituição de ensino também tem o dever de servir como exemplo e local de reflexão para a construção de valores pautados em princípios éticos dentro e fora da instituição O compliance sustenta todos os esforços envidados pela instituição para o estrito cumprimento das exigências legais e, logo, reduz os riscos de possíveis desvios de conduta. Busca a preservação da imagem institucional e contribui para a produção de novos conhecimentos. A presente pesquisa tem como objetivo realizar uma revisão bibliográfica sobre o compliance nos Institutos Federais, com um olhar sobre sua implementação no Instituto Federal de Brasília, passando pela importância dos IF na formação cidadã.
Tendências atuais sobre o Ensino de Física Moderna: uma revisão de literatura
Authors: Januário Maria Derlandia de Araújo , Hoernig André Felipe , Massoni Neusa Teresinha
Published: January 2024

Este artigo é uma revisão de literatura que explora tópicos de Física Moderna (FM) no contexto do Ensino de Física, como parte de um estudo de doutoramento que tem como objetivo introduzir FM no Ensino Médio (EM) com uma visão histórica e epistemológica da Ciência, fazendo uso da argumentação científica. Dessa forma, este artigo buscou responder: Com base na literatura da área, quais são as principais temáticas da FM trabalhadas, com um olhar histórico e epistemológico? Que conceitos, estratégias e tendências aponta a literatura para serem explorados na Educação Básica? A análise qualitativa revelou que os artigos tratam de várias temáticas de FM, com uma linguagem robusta ao EM. A Teoria da Relatividade se destaca na pesquisa, embora não haja uma indicação conclusiva sobre qual aspecto da teoria deve ser abordado. Mas, por meio da análise de conteúdo foi possível identificar quatro categorias de como os conceitos da teoria são discutidos na área. Ainda que não se tenha chegado a uma estratégia definitiva para o ensino em sala de aula, a revisão fornece base e fundamentação para entendermos que trabalhar Relatividade no EM é uma via útil para propor uma abordagem interdisciplinar e histórica, e construir nos alunos habilidades e pensamento crítico, como também permite compreender algumas tecnologias presentes na contemporaneidade.
Hasfalat infiltráló coecum tumor eltávolítása komplett mesocolicus excisióval, hasfali resectióval és musculus tensor fasciae latae musculocutan lebenyes rekonstrukcióval

A korai és lokálisan előrehaladott colontumorok esetében a megfelelő onkológiai minőségű sebészi resectio a kezelés központi eleme. Jobb oldali vastagbél tumorok sebészi ellátásában – a kedvezőbb hosszú távú onkológiai eredmények elérése céljából – egyre szélesebb körben elfogadott a Hohenberger által 2009-ben elsőként publikált „complett mesocolicus-excisio” (CME) és centrális érlekötés (CVL).

Esetünkben egy 78 éves nőbeteg jobb alhasi faeculens váladékozása miatt indult kivizsgálása során a hasfalat szélesen infiltráló coecum tumor igazolódott. Az Onkoterápiás Bizottság – tekintettel az egyértelmű távoli áttét hiányára, a beteg jó általános állapotára, a fennálló colo-cutan sipolyra és egyértelmű irresecabilitási jelek hiányára – műtétet javasolt. A kuratív intenció és kellő radikalitás érdekében, komplett mesocolicus excisio és kiterjesztett hasfali resectio mellett döntöttünk. A műtét során a kialakult hasfali defektus rekonstrukciójához a jobb comb lateralis felszínéről tensor fasciae lateae musculocutan (TFL) lebenyt preparáltunk. A hasfali defektust, mind a fascia, mind a subcutis-cutis rétegében helyreállítottuk, a donor területet primeren zártuk. A posztoperatívumban a lebeny distalis végén vénás pangás jelei majd felületes necrosis mutatkozott. Sorozatos necrectomia és negatívnyomás-terápia (NPWT) mellett a hasfal végig intakt maradt és per secundam gyógyult.

Megfelelő betegszelekció esetén, centrumokban elvégezve – onkosebész és helyreállító plasztikai sebész szoros együttműködésével – a radikális műtét kiterjesztett hasfali resectiót igénylő jobb colonfél tumoroknál is biztonsággal elvégezhető.
Integrity of Quranic Legislations
Authors: Salem Ahmed Ali
Published: January 2024

Abrogation is claimed to be required to resolve alleged contradictions between legislations in the Qu'ran, the Prophet’s Sunna, or both. The opponents of abrogation find the alleged contradictions imaginary because the Qu'ran is coherent and the legislative Sunna is its perfect implementation that God endorsed. Accordingly, the Quranic legislations are fully consistent if their different conditions and ultimate goals are considered. Different legislative verses were revealed in different circumstances to be applicable later in similar circumstances. Applying the Quranic legislations and the Prophet’s Sunna carefully in appropriate contexts can prove the integrity, consistency, universality, and eternity of the Quranic legislations. This article critically reviews the debate on the abrogation claim in Arabic literature, both classical and modern—debate that has important theological, legal and practical implications.
The influence of emotional intelligence awareness on the teaching experiences of university teacher trainees: a quantitative and qualitative analysis
Authors: Dick-Bursztyn Marta
Published: January 2024

Educating prospective teachers is a complex and interdisciplinary effort, encompassing educational policies, core subject knowledge, and honing essential skills, attitudes, and behaviours necessary for effective classroom teaching. This study focuses on the initial stage of teacher development, exploring how pre-service university students perceive and understand emotional intelligence (EI) and its components, especially as they embark on internships in primary and secondary schools. The emotional dynamics in English language teaching classrooms, involving various emotions among students, teachers, parents, and colleagues are examined. The study underscores the importance of emotional expertise for both students and teachers in facilitating a productive teaching and learning process. A review of relevant literature reveals that while there is extensive research on emotions in teacher training, the emphasis has been primarily on general education, with limited focus on second-language teacher education. EI is seen as a critical factor in teachers' classroom management, pedagogical skills, and overall success within the profession. Additionally, studies on EI within English as a foreign language (EFL) teacher education are relatively scarce but indicate a significant impact on teaching outcomes. This research employs a mixed-methods approach to investigate pre-service teachers' perceptions of EI. Quantitative data was collected through a survey questionnaire measuring participants' agreement with statements related to EI. Qualitative data was obtained through in-depth interviews with selected pre-service teachers. The study involved 32 pre-service university students enrolled in English language teacher education programs about to begin internships at primary and secondary schools in Poland.
Exploring the relationship between willingness to communicate and cultural capital in a language learning context - a qualitative investigation
Authors: Trinder Magdalena
Published: January 2024

The qualitative study is intended to determine if there is a potential relationship between willingness to communicate and cultural capital in young learners of English and whether it may be possible to assess levels of cultural capital and cultural participation in a quantitative fashion, which would then open the way for a broader range of studies that would allow for regressive analysis of the relationship between cultural capital and a broad range of individual differences to determine the extent to which this may be a key factor in language acquisition and learning. The qualitative investigation was conducted on five participants who were willing to give interviews during a language camp in the UK in the summer of 2022. All five of the participants scored highly on a WTC assessment scale and also showed confidence in communicating in a non-classroom environment. The tentative findings of the study would appear to indicate that there is a firm basis for further research on a quantitative scale in order to validate the basic hypothesis.
