Erosão na prainha da vila de Encantadas na Ilha do Mel, litoral do Paraná, Brasil
No full texthttps://doi.org/10.53766/RGV/2024.65.1.11The village de Encantadas (VEIM) has been suffering from a situation of beach erosion. The problem is a result of the confluence of physical and anthropic phenomena; it is a present condition inherited from the increase in the incidence and intensity of physical and human variables in recent periods. Cumulatively, the sedimentary stock deficit has resulted in soil loss towards the interior of the village, causing damage such as the loss of circulation, mobility, and transit space, as well as the deterioration of residential and, mainly, commercial buildings. The impacts suffered have mobilized organized social groups from the local community, and based on their request, a technical visit was carried out followed by conversations and guidance. A report of this experience is presented, aiming to subsidize further technical referrals regarding the identified problems.https://doi.org/10.53766/RGV/2024.65.1.11La villa de Encantadas en la Ilha do Mel (VEIM) presenta una situación de erosión de la playa.

Get PDFAnálisis espaciotemporal de la deforestación en el campus mutile (2005-2023) usando Google Earth Engine Spatio-temporal analysis of deforestation on the mutile campus (2005-2023) using Google Earth Engine
Get PDFThis study analyzes deforestation in the Mutile campus of the Universidad Técnica Luis Vargas Torres between 2005 and 2023, using satellite images processed with Google Earth Engine (GEE). The main objective is to quantify the total deforested area, identify the years with the greatest loss of forest cover, and analyze the trend of deforestation over time. By analyzing images from Landsat 5, 7 and 8 satellites, a total loss of 51.82 ha was estimated, with significant peaks in the years 2017 and 2012, where 18.9 ha and 11.97 ha of deforestation were recorded, respectively. Statistical analysis revealed an annual mean deforestation of 5.03 ha, with a standard deviation of 6.86 ha, indicating high variability in the data. In addition, the linear regression showed a slope of 0.11 ha/year, suggesting a moderately increasing trend of deforestation over the period studied. Visualization using a boxplot highlighted the presence of outliers, reflecting sporadic events of high intensity illegal logging. Recommendations include the establishment of a continuous monitoring system with ESG, the strengthening of surveillance, and the implementation of conservation policies in critical areas of the campus. This study highlights the importance of remote sensing for sustainable management of forest resources in vulnerable areas.Este estudio analiza la deforestación en el campus Mutile de la Universidad Técnica Luis Vargas Torres entre 2005 y 2023, utilizando imágenes satelitales procesadas con Google Earth Engine (GEE). El objetivo principal es cuantificar el área total deforestada, identificar los años con mayor pérdida de cobertura forestal y analizar la tendencia de la deforestación a lo largo del tiempo. Mediante el análisis de imágenes de los satélites Landsat 5, 7 y 8, se estimó una pérdida total de 51.82 hectáreas, con picos significativos en los años 2017 y 2012, donde se registraron 18.9 ha y 11.97 ha de deforestación, respectivamente. El análisis estadístico reveló una media anual de deforestación de 5.03 ha, con una desviación estándar de 6.86 ha, lo que indica una alta variabilidad en los datos. Además, la regresión lineal mostró una pendiente de 0.11 ha/año, sugiriendo una tendencia moderadamente creciente de deforestación en el periodo estudiado.

Efecto de la dieta cetogénica en la prevención del desarrollo de diabetes mellitus tipo 2. Revisión narrativa Effect of the ketogenic diet on the prevention of the development of type 2 diabetes mellitus. Narrative review
Get PDFThe benefits of diet and exercise have also been studied alongside other toxic habits, such as smoking and alcohol. The result has been quite beneficial, making it clear that those people who lead a healthier lifestyle, not only limited to diet and exercise, have a lower risk of up to 75% of developing diabetes. Despite the existence of different diet modalities, those based on carbohydrate restriction, especially the ketogenic diet, are the ones that have aroused the most interest in recent years, as they promise multiple benefits in metabolic risk factors. The objective of this bibliographic review was to offer updated biomedical information regarding the effect of the ketogenic diet in the prevention of type 2 diabetes mellitus. The search was carried out in three biomedical databases, such as PubMed, VHL and SCOPUS, in which a total of 533 articles were obtained, and of which 12 were included. The ketogenic diet was considered the only intervention, likewise, diets that included a carbohydrate intake of less than 50 g were considered ketogenic. /day. As main results, a significant improvement in metabolic parameters and body composition was obtained in participants with a diagnosis of overweight/obesity/prediabetes/metabolic syndrome and without type 2 diabetes, in whom a significant reduction in body weight, abdominal circumference was achieved, BMI (body mass index), fasting glycemia and IR-HOMA (HOMA index).DOI: https://doi.org/10.53766/GICOS/2024.01.09.04RESUMENLos beneficios de la dieta y el ejercicio también se han estudiado junto con otros hábitos tóxicos, como el tabaquismo y el alcohol. El resultado ha sido bastante beneficioso, dejando en claro que, aquellas personas que llevan un estilo de vida más saludable, no solamente limitado a dieta y ejercicio presentan un riesgo menor, de hasta el 75% de desarrollar diabetes. A pesar de existir diferentes modalidades de dieta, las que se basan en la restricción de carbohidratos, en especial la dieta cetogénica, son las que más han despertado el interés en los últimos años, pues prometen múltiples beneficios en los factores de riesgo metabólicos. El objetivo de esta revisión bibliográfica fue ofrecer información biomédica actualizada referente al efecto de la dieta cetogénica en la prevención de la diabetes mellitus tipo 2. Se llevó a cabo la búsqueda en tres bases de datos biomédicas, como son, PubMed, BVS y SCOPUS, en las que se obtuvo un total de 533 artículos, y de los cuales se incluyeron 12. Se consideró a la dieta cetogénica como única intervención, así mismo, se contempló como cetogénica a las dietas que incluían un aporte de carbohidratos menor a 50 g/día. Como principales resultados, se obtuvo una mejora importante de los parámetros metabólicos y en la composición corporal en participantes con diagnóstico de sobrepeso/obesidad/prediabetes/síndrome metabólico y sin diabetes tipo 2, en quienes se logró una reducción significativa en el peso corporal, circunferencia abdominal, IMC (índice de masa corporal), glucemia en ayunas e IR-HOMA (índice de HOMA).ABSTRACT The benefits of diet and exercise have also been studied alongside other toxic habits, such as smoking and alcohol.

Get PDFThe article addresses the importance of training future teachers in professional ethics for inclusive education, with special emphasis on respect for the LGBTIQ+ community. The objective is to analyze the perceptions of the students of the Pedagogy of Experimental Sciences of Chemistry and Biology of the Technical University “Luis Vargas Torres” about the educational inclusion of the LGBTIQ+ community, identifying social and cultural barriers that perpetuate discrimination. The methodology employed was a mixed approach, using surveys and semi-structured interviews. Quantitative data were collected through surveys of 60 students and interviews were conducted with teachers to obtain qualitative information. In addition, key documents related to educational inclusion were reviewed. The results show that, although progress has been made in inclusive policies, there are still cultural and social barriers that hinder their implementation. Fourteen percent of respondents considered homosexuality to be an illness, reflecting the need for more education on sexual diversity. The conclusions highlight the urgency of reforming teacher training to include content on sexual diversity and human rights, in order to combat discriminatory attitudes that persist in the educational environment. It is essential to promote a profound cultural change that dismantles prejudices and fosters an inclusive and respectful environment in educational institutions.El artículo aborda la importancia de la formación de futuros docentes en la ética profesional para una educación inclusiva, con especial énfasis en el respeto a la comunidad LGBTIQ+.

La práctica escolar cotidiana como objeto de la innovación pedagógica
Get PDFThe presentation explains the pedagogical orientation of daily school practice as an object of formative innovation. It is assumed that improving the formative quality of education requires a critical and constructive analysis of the events that characterize the classroom reality. The impediment to change lies in the pedagogical permanence of the transmission of knowledge as an obstacle to interpreting the complex reality of the contemporary world. In this regard, it is proposed to practice the fundamentals of qualitative research as a basis for transforming the work of the classroom. Methodologically, a bibliographic review was carried out to structure an explanation about the generation of knowledge from qualitative research. It is concluded that in the globalized scenario, the educational training of citizens requires the use of investigative processes that promote analytical, reflective and critical educational training, to motivate the pedagogical quality of the educational act.La ponencia explica la práctica escolar cotidiana como objeto de la innovación pedagogica. Se asume que mejorar la calidad formativa de la educación, requiere el análisis crítico y constructivo de los sucesos que caracterizan la realidad áulica. El impedimento del cambio radica en la permanencia pedagógica de la transmisión de conocimientos como obstáculo para interpretar la compleja realidad del mundo contemporáneo. Al respecto, se propone practicar los fundamentos de la investigación cualitativa como base de la transformación de la labor del aula de clase. Metodológicamente, se realizó una revisión bibliográfica para estructurar una explicación sobre la generación del conocimiento desde la investigación cualitativa. Se concluye que en el escenario globalizado, la formación educativa de los ciudadanos exige la utilización de los procesos investigativos que promuevan la formación educativa analítica, reflexiva y crítica, para motivar la calidad pedagógica del acto educante.Recibido: 05/10/2021 Aceptado: 27/11/202
