Indicadores como ferramenta para análise e avaliação de Educação Ambiental: Estudo de Caso no Colégio Militar de Curitiba
Full text linkThis study investigated Environmental Education (EE) practices at the Military School of Curitiba (CMC) . The methodology, with a participatory approach, used document analysis and the application of the Indicator Matrix (Vieira, 2021), grounded in the Theory of Policy Enactment by Ball, Maguire, and Braun (2021). The analysis of the Management dimension revealed that, despite the hierarchical and militarized structure, the institution has implemented democratic management mechanisms. The assessment of the Physical Space dimension showed that, while the school infrastructure is excellent, green spaces are underutilized, highlighting a need for increased awareness regarding sustainability within the school grounds. In the Curriculum dimension analysis, although the CMC has highly qualified staff, there is limited representation of teachers specialized in EE. Lastly, as for the Community dimension, participants reported significant engagement in internal academic projects and activities, yet the involvement of EE initiatives with the external community remains limited.Este estudio investigó las prácticas de Educación Ambiental (EA) en el Colegio Militar de Curitiba (CMC) a través de un estudio de caso con diecinueve participantes. La metodología empleó el análisis documental y la aplicación de la Matriz de Indicadores (Vieira, 2021), basada en la Teoría de Actuación Política de Ball, Maguire y Braun (2021). El análisis del indicador Gestión indicó que, a pesar de la estructura jerárquica y militarizada, la institución ha implementado mecanismos de gestión democrática. La evaluación del indicador Espacio físico reveló que, aunque la infraestructura escolar es excelente, el uso de los espacios verdes está subestimado, señalando la necesidad de una mayor concienciación sobre sostenibilidad en las instalaciones del colegio. En el análisis de Currículo, aunque el CMC cuenta con profesionales altamente cualificados, la presencia de docentes especializados en EA es limitada. Finalmente, en la dimensión Comunidad, los participantes de la investigación informaron interacciones significativas en proyectos y actividades académicas internas, pero el involucramiento en acciones de EA con la comunidad externa sigue siendo limitado.Este artigo teve como objetivo investigar as práticas de Educação Ambiental (EA) no Colégio Militar de Curitiba (CMC).

Caracterización estructural de la Cuenca del Catatumbo (Colombia): una revisión a partir del análisis microtectónico de núcleos de pozos: Caracterização estrutural da Bacia de Catatumbo (Colômbia): uma revisão baseada na análise microtectônica de testemunhos de poços
No full textFrom the microtectonic analysis of drill cores from oil fields in the Catatumbo Basin, complemented with well image data and regional interpretations, two major tectosedimentary episodes are recognized that influence the definition of its petroleum system: a) an early extensional one where the sequences exhibit progressive evidence of compaction by burial associated with Mesozoic and Paleogene sedimentation that generates subvertical fractures with carbonate fillings originating from the dissolution of stylolitic surfaces by overloading of the overlying sequences and b) another late Cenozoic episode associated with the consequences of the ENE-WSW Andean convergence that provides a submeridian transpressive context that reactivates the venulations as more fragile mechanical discontinuities in senestral transpression. The evolutionary history of deformation expressed by microtectonic core data provides information on the chronology of the petroleum system, whose first stage of compaction is associated with the maturation and expulsion of fluids and the second stage with the generation of fracturing that increases the secondary porosity and permeability of the fields. In the case of reinterventions and development of unconventional hydrocarbons, wells should be directed in the WSW-ENE direction and subhorizontally of the minimum principal stress (s3) to traverse the greatest number of potentially open subvertical fractures per linear meter.A partir del análisis microtectónico de núcleos de perforación de pozos de campos petroleros de la Cuenca Catatumbo, complementada con datos de imágenes de pozos e interpretaciones regionales, se reconocen dos grandes episodios tectosedimentarios que influyen sobre la definición de su sistema petrolero: a) uno temprano extensional donde las secuencias exhiben evidencias progresivas de compactación por enterramiento asociado a la sedimentación mesozoica y paleógena que genera fracturas subverticales con rellenos carbonáticos provenientes de la disolución de las superficies estilolíticas por sobrecarga de las secuencias suprayacentes y b) otro tardío cenozoico asociado a las consecuencias de la convergencia Andina ENE-OSO que proporciona un contexto transpresivo submerianal que reactiva las venulaciones como discontinuidades mecánicas más frágiles en transpresión senestral. La historia evolutiva de la deformación expresada por los datos microtectónicos de los núcleos aporta información sobre la cronología del sistema petrolero cuyo primer estadio de compactación se asocia con la maduración y expulsión de fluidos y, el segundo, con la generación de la fracturación que incrementa la porosidad y permeabilidad secundaria de los campos. En el caso de realizarse reintervenciones y desarrollo de hidrocarburos no convencionales, los pozos deberán ser dirigidos en la dirección OSO-ENE y subhorizontalmente del esfuerzo principal mínimo (s3) para atravesar la mayor cantidad de fracturas subverticales potencialmente abiertas por metro lineal.Resumen.

Influências antropogênicas nas taxas de denudação química e física na bacia do Rio das Araras, Araras (SP): Anthropogenic influences on chemical and physical denudation rates in the Rio das Araras basin, Araras (SP)
Full text linkRESUMO - Avaliações das taxas de denudação química e física associadas ao intemperismo químico e remoção de solos, respectivamente, vêm sendo realizadas em bacias hidrográficas por todo o mundo. Contudo, poucos trabalhos abordam os impactos das atividades humanas na evolução de relevo. O presente trabalho estimou as taxas de denudação química e física, a partir dos fluxos de sólidos totais dissolvidos (STD) e em sólidos totais em suspensão (STS), em cinco pontos de amostragem ao longo da bacia do Rio das Araras, interior do estado de São Paulo. Os valores de pH foram próximos à neutralidade, com as menores temperaturas das águas fluviais caracterizadas nos meses de inverno. Os valores de condutividade elétrica foram influenciados devido ao lançamento de efluentes urbanos da cidade diretamente no Rio das Araras. As [STS] foram inversamente aos obtidos para [STD], representando os processos de diluição das águas fluviais e remoção de solos pela erosão hídrica no período chuvoso. Houve claramente influência antrópica nas taxas de denudação química e física na bacia do Rio das Araras, especialmente ao lançamento de efluentes urbanos no Rio das Araras e remoção de solos nas áreas de plantações de cana-de-açúcar, respectivamente, indicando que os sistemas de paisagem humana estão afetando os processos naturais de denudação.

ABSTRACT - Assessments of chemical and physical denudation rates associated with chemical weathering and soil removal. However, few studies address the impacts by human activities on the landscape evolution. The present study estimated the chemical and physical denudation rates, based on fluxes of total dissolved solids (TDS) and total suspended solids (TSS), at five sampling points along the Araras River basin, interior of the state of São Paulo. The pH values were close to neutrality, with the lowest fluvial water temperatures characterized in the winter months. The EC values were influenced by the discharge of urban effluents released directly into Araras River. The [STS] were inversely related to those obtained for [STD], representing the processes of dilution of fluvial waters and soil removal by water erosion during the rainy season. There was clearly anthropogenic influence on the chemical and physical denudation rates in the Araras River basin, especially due to release of urban effluents into Araras River and soil removal in the sugarcane crops, respectively, indicating that human-landscape systems are affecting the natural denudation processes.

Dinâmica da Cobertura e Uso da Terra no Vale do Arinos, Mato Grosso, 1990 a 2020
Full text linkGeotechnologies are an important instrument for monitoring human actions and thus, this article aimed to identify changes in Land Use and Coverage in the Arinos Valley region, Mato Grosso. To analyze the changes, images from the years 1990, 2000, 2010 and 2020 from the annual mapping of Land Use and Cover of the MapBiomas Project were used, with the generation of satellite image maps from the LANDSAT 7 collections. It was carried out multivariate statistical analysis, Pearson\u27s correlation network analysis and canonical variable analysis were performed, identifying the factors that suffered the most correlations with use and occupation. The results indicated that significant changes occurred, in which the growth of urban infrastructure and agricultural activity resulted in the reduction of native forests, with an increase in anthropic formations. These changes, driven by factors such as global demand for commodities and policies to encourage production, generated the expansion of agricultural areas, through soybean cultivation, a threat to the remaining forest areas.Las geotecnologías son un instrumento importante para el seguimiento de las acciones humanas y, por lo tanto, este artículo tuvo como objetivo identificar cambios en el Uso y Cobertura del Suelo en la región de Vale do Arinos, Mato Grosso. Para analizar los cambios se utilizaron imágenes de los años 1990, 2000, 2010 y 2020 provenientes del mapeo anual de Uso y Cobertura del Suelo del Proyecto MapBiomas, con la generación de mapas de imágenes satelitales de la colección LANDSAT 7. Se realizaron análisis estadísticos multivariados, análisis de Redes de Correlación de Pearson y análisis de variables canónicas, identificando los factores que más sufrieron correlaciones en Uso y Ocupación. Los resultados indicaron que ocurrieron cambios significativos, en los que el crecimiento de la infraestructura urbana y la actividad agrícola resultaron en una disminución de los bosques nativos, con un aumento de las formaciones antropogénicas. Estos cambios, impulsados por factores como la demanda de commodities y las políticas de incentivo a la producción, generaron el avance de las áreas agrícolas, debido principalmente al cultivo de soja, una amenaza para las áreas forestales restantes.As geotecnologias são um importante instrumento para monitoramento das ações antrópicas e suas intervenções no ambiente. Diante disso, o presente artigo objetivou identificar as alterações no Uso e Cobertura da Terra na região do Vale do Arinos, Mato Grosso. Para a análise das mudanças foram utilizadas imagens dos anos 1990, 2000, 2010 e 2020 do mapeamento anual de Uso e Cobertura da Terra do Projeto MapBiomas, com a geração de mapas de imagens de satélite da coleção LANDSAT 7. Foi realizada a análise estatística multivariada, análise de Rede de Correlações de Pearson e análise de variáveis canônicas, identificando os fatores que mais sofreram correlações do uso e ocupação. Os resultados indicaram que ocorreram mudanças expressivas, no qual o crescimento da infraestrutura urbana e atividade agropecuária resultaram na diminuição das florestas nativas, com aumento das atividades antrópicas. Essas mudanças, impulsionadas por fatores como a demanda por commodities e políticas de incentivo à produção, geraram avanço das áreas de agropecuária, sobretudo pelo cultivo da soja, uma ameaça às áreas florestais remanescentes

Impact of the COVID-19 pandemic on the scientific production of a graduate program in Movement Sciences
Full text linkAbstract - Aim To investigate the impact of the COVID-19 pandemic on the scientific production of the graduate program in Movement Sciences of the Federal University of Mato Grosso do Sul. Methods: The scientific production of the program was assessed in terms of quantity (number of studies) and quality (Qualis/CAPES rank score and Web of Science® Journal Citation Reports). Chi-squared crosstab tests were used to compare the data according to year of publication of the studies, sex of the researchers, Qualis/CAPES rank score, and Journal Citation Reports. Significance was set at 5%. Results: The number of studies decreased by 30.2% during the COVID-19 pandemic (P = 0.011). Publications were similar according to researchers\u27 sex (P = 0.666). The Qualis/CAPES rank score of the studies was not affected by the COVID-19 pandemic (P = 0.227). Differently, the impact factor was affected (P = 0.039). The median Journal Citation Report of the scientific production of the researchers decreases from 4.091 in 2020 to 3.346 in 2022. Conclusion: The COVID-19 pandemic affected the number of studies published by researcher of the graduate program in Movement Sciences of the Federal University of Mato Grosso do Sul. While the Qualis/CAPES rank score of the studies remained unchanged, the median Journal Citation Reports declined. Although this study highlighted the reality of a specific program in Movement Sciences, the findings may be similar across other programs. This should alert funding agencies to the impact of the COVID-19 pandemic on scientific production within Movement Sciences programsAbstract - Aim To investigate the impact of the COVID-19 pandemic on the scientific production of the graduate program in Movement Sciences of the Federal University of Mato Grosso do Sul.

A situação dos Espaços Urbanos em Moçambique: de 1980 a 2017
Full text linkMozambican urban spaces are a product of the colonial period. After National Independence, several initiatives were taken by the FRELIMO Government with the aim of changing the urban duality, strongly marked by racial discrimination, however, without the expected outcome. Urban spaces were reclassified, with rural areas incorporated into urban space. It is likely that the implementation of this measure has changed the contents of urbanity, defined by Araújo. Almost 50 years after independence, it is urgent to analyze the current stage of urbanization, based on the analysis of the contents of urbanity, namely: (i) building materials; (ii) water access; (iii) access environmental sanitation; and (iv) access to electricity. The study analyzes the evolution of these indicators based on data from the 1980, 1997 and 2017 census. Based on the data from 1980 census we adjusted the indicators so that the contents of the indicators are comparable. The data analysis shows two main changes: The northern region that includes Zambezia province has collected less compared to the other regions of the country and in contracts, and, apart from Inhambane, the Southern region recorded more changes/gains.Los espacios urbanos de Mozambique son producto del período colonial. Después de la Independencia Nacional, varias iniciativas fueron desbaratadas por el Gobierno del FRELIMO con el objetivo de cambiar la dualidad urbana, fuertemente marcada por la discriminación racial, pero sin el éxito esperado. Se reclasificaron los espacios urbanos, incorporándose las zonas rurales. Es probable que la implementación de esta medida haya cambiado los contenidos de la urbanidad, definida por Araújo. Casi pasados 50 años de la independencia, urge analizar la etapa actual de la urbanización, a partir del análisis de los contenidos de la urbanidad, a saber: (i) materiales de construcción; (ii) acceso al agua; (iii) acceso al saneamiento ambiental; y (iv) acceso a la electricidad. El estudio analiza la evolución de estos indicadores con base en datos de los censos de 1980, 1997 y 2017. Para permitir que los contenidos de los indicadores sean comparables, se decidió ajustarlos con base en la información del censo de 1980. Los datos muestran importantes avances en tres regiones del país. Sin embargo, la región Norte, incluyendo la provincia de Zambezia, es la que ha obtenido menores avances y la región Sur, excluida la provincia de Inhambane, es la que ha registrado mayores beneficios.Os espaços urbanos moçambicanos são um produto do período colonial.

Learning outcomes vis-à-vis nutritional status, physical activity, and cognitive function: a cross-sectional study
Full text linkAim: This cross-sectional study aims to determine the relationship of nutritional status, physical activity, and cognitive function to the learning outcomes of junior high school students in the country. Methods: This study employed a correlational approach in order to determine the relationship among the variables. Due to time constraints, data from 1870 students were used to draw conclusions using Simple Random sampling technique. The Physical Activity Questionnaire for Older Children (PAQ-C) was utilized in the study. Additionally, concerning food intake, is determined by Body Mass Index (BMI). Moreover, the academic performance was measured by depending on the grades or numerical representations, using the Concentration Grid Test to measure cognitive function (CGT). Results: It was observed that there is a positive and significant relationship between nutritional status (X1) [r(1868) = .870, p = .001], physical activity (X2) [r(1868) = .748, p = .013], and cognitive function (X3) [r(1868) = .895, p < .05] (X3) with learning outcomes. Furthermore, a significant relationship was also observed between nutritional status (X1) and physical activity (X2) [r(1868) = .742, p = .014], and nutritional status (X1) and cognitive function (X3) [r(1868) = .857, p = .002]. Based on the multiple regression results, dietary intake (X1), physical activity (X2), cognitive function (X3), and learning outcomes (Y) have a 0.725 association. Nutritional status (X1), physical activity (X2), and cognitive function (X3) account for 52.5% of learning outcomes (Y), whereas other variables account for 47.5%. Sig. F change 0.006 (p < 0.05) shows a simultaneous and substantial association between nutritional status (X1), physical activity (X2), and cognitive performance (X3) among junior high school students Conclusion: Nutritional status, physical activity, cognitive function, and learning outcomes are strongly linkedAim: In this regard, this cross-sectional study aims to determine the relationship of nutritional status, physical activity, and cognitive function to the learning outcomes of junior high school students in the country.

Ecopontos: normas e o caso de Sertãozinho-SP
Full text linkThis study aimed to analyse the ecopontos (ecological waste drop-off points) in the municipality of Sertãozinho-SP, drawing on the relevant legal frameworks and the Municipal Plan for Integrated Solid Waste Management (PMGIRS) of Sertãozinho-SP. The research employed an exploratory method, using documentary analysis of laws, plans, and technical regulations that establish and govern the creation and management of ecopontos. The analysis highlights the absence of national legislation specifically addressing ecopontos; the development of the ecoponto infrastructure in Sertãozinho; and the enactment of a municipal law on the subject. It also underscores the lack of detailed provisions concerning the structure and management of ecopontos, as well as the absence of clear targets within the PMGIRS, both of which may hinder future initiatives and monitoring by residents.Este estudio tiene como objetivo analizar los ecopuntos en el municipio de Sertãozinho, São Paulo, con base en las normas legales y el plan municipal de gestión integrada de residuos sólidos. Para ello, se empleó un método de investigación exploratoria, que incluyó el análisis documental de leyes, planes y reglamentos técnicos que establecen y regulan la creación y gestión de ecopuntos. Con base en esto, se identificaron los siguientes hallazgos: la falta de legislación nacional sobre ecopuntos; la evolución de la estructura de ecopuntos en el municipio de Sertãozinho; y la promulgación de una ley municipal sobre el tema. Cabe destacar la falta de mayor detalle sobre la estructura y la gestión de los ecopuntos, así como de objetivos detallados sobre el tema en el PMGIRS, lo que podría dificultar futuras acciones y el seguimiento por parte de los residentes.O trabalho objetiva analisar os ecopontos do município de Sertãozinho-SP, a partir das normas jurídicas e do plano municipal de gestão integrada de resíduos sólidos de Sertãozinho-SP. Para tal, utilizou-se como método de pesquisa a técnica exploratória por análise documental de leis, planos e normativas técnicas que instituem e regulamentam a criação e gerenciamento de ecopontos. A partir disso, identificam-se: falta de legislação nacional tratando sobre ecopontos; evolução da estrutura de ecopontos no município de Sertãozinho; e instituição de lei municipal sobre o tema. Ressalta-se falta de maior detalhamento da estrutura e gestão dos ecopontos, bem como de metas detalhadas sobre o tema no PMGIRS, o que pode dificultar ações futuras e o acompanhamento pelos munícipes
Síndrome de burnout em profissionais que atuaram na linha de frente nas unidades de terapia intensiva no combate a Covid-19: DOI: 10.5281/zenodo.18062181
No full textA Síndrome de Burnout (SB) em profissionais de saúde pode ser causada por exposição contínua a fatores estressores no ambiente de trabalho. Este estudo identificou profissionais de UTIs do agreste e sertão de Pernambuco em risco potencial para desenvolver SB durante a atuação na linha de frente contra a COVID-19. Utilizando o Burnout Assessment Tool (BAT), observou-se um elevado número de profissionais com risco muito alto (percentil > 75%). Mulheres apresentaram maiores níveis de exaustão, queixas psicológicas e psicossomáticas, enquanto a idade esteve associada a declínio cognitivo (p < 0.05). Profissionais com atividades de lazer ou que praticavam exercícios físicos apresentaram menores níveis de Burnout (p < 0.05). Entre os fatores pessoais determinantes destacaram-se sexo e idade, enquanto entre os ocupacionais sobressaíram carga horária, número de vínculos, horas extras, prática de atividade física e lazer
