Uno de los pilares en los que se sostiene la reforma curricular en nuestro país viene a ser la supervisión educativa, proceso sistemático que debe procurar desarrollar las capacidades y competencias de los profesores de aula con la finalidad de mejorar el desempeño docente y de esta manera asegurar el logro de aprendizajes de los estudiantes. El objetivo principal del estudio desarrollado ha sido determinar la relación entre la supervisión educativa y el logro de aprendizaje de los estudiantes del nivel secundario de las instituciones educativas ubicadas en el distrito Jesús Nazareno del departamento de Ayacucho. El enfoque de investigación utilizado ha sido el cuantitativo y el diseño empleado en el proceso de la investigación fue el descriptivo correlacional. La muestra de estudio estuvo conformada por 60 docentes y la técnica y el instrumento utilizado para el registro de datos fue la encuesta y el cuestionario. Los resultados obtenidos registran que el 51,7% (31) de docentes opinan que la supervisión educativa es buena y el 60,0% (36) de docentes opinan que los logros de aprendizaje alcanzado por los estudiantes se ubican en la valoración logro previsto, evidenciándose la efectividad de esta estrategia metodológica. Las conclusiones afirman que, existe relación directa y significativa entre la supervisión educativa y los logros de aprendizaje, en razón de que el valor de rho = 0,613, lo que significa que el seguimiento, acompañamiento y monitoreo en aula al profesor, favorece los procesos didácticos y asegura el logro de aprendizaje de los estudiantes.","PeriodicalId":21546,"journal":{"name":"Revista ECIPeru","volume":"101 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85237346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

En el presente trabajo de investigación tiene como objetivo determinar la influencia del agua termal sobre las propiedades físicas del concreto, buscando reemplazar el agua potable de la mezcla de concreto con el agua termal de la piscina San Cristóbal en la ciudad de Huancavelica. Se realiza estudios físicos y químicos al agua para ser usada en la elaboración de concreto. El diseño de mezcla para resistencias de: f’c = 210 kg/cm2, según el método ACI 211; para ello utilizamos agregado grueso de cantera Ocopa (Lircay), fino de cantera Orcotuna (Huancayo), cemento Andino Extraforte, agua termal con diferentes concentraciones de 25%,50%,75%,100% y agua potable como control positivo, se elaboró 60 probetas de concreto de 6 por 12 pulgadas. Se estudia el comportamiento del concreto en estado fresco y endurecido a edades de 7, 14 y 28 días, respecto al primero se determinó el asentamiento, peso unitario y al estado endurecido la resistencia a compresión, peso unitario. La presencia de agua termal en el concreto fresco en porcentajes de 25%,50%,75%, 100% aumenta la consistencia de la mezcla (asentamiento) en 3.3 pulg, 3.4 pulg, 3.6 pulg, 3.7 pulg respectivamente ; en estado endurecido, la resistencia a compresión a 28 días al aumentar porcentajes de 25%,50%,75%, 100% de agua termales es de 217 kg/cm2, 212.53 kg/cm2, 208 kg/cm2 y 203 kg/cm2 respectivamente y los pesos unitarios permanecen sin cambios significativos. Se concluye que es factible el uso del agua termal en la preparación del concreto puesto que cumple con los requisitos mínimos que señala la Norma Técnica Peruana, especialmente el 25% de agua termal a 14 días incrementa la resistencia en más de 10% de resistencia esperada; siendo en todos los casos aptos para su utilización según la norma, lo que produciría un impacto positivo, reduciendo el uso de agua potable y llegar a ser empleada en contexto local Huancavelicano.","PeriodicalId":21546,"journal":{"name":"Revista ECIPeru","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73923967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research approach is quantitative and the research design is non-experimental of a cross- sectional type. The data of this study arise from a non-probabilistic sample\u0000made up of 342 students from the Universidad Privada del Norte from Lima, Peru who belong to the professional careers of Nutrition and Dietetics (n = 90), Nursing (n = 85), Obstetrics (n = 85) and Physical Therapy and Rehabilitation (n = 82) The unit of analysis was made up of students who took the subject of Introduction to Nutrition in the academic year 2019-II. It is observed that of the total, 47% of Health Sciences students have a moderate level of nutritional education, followed by 35% of students with a low level and 18% has a high level of nutritional education. Regarding eating habits, 39% of all students have a moderate level, followed by 32% who has a low level and 29% has a high level. It is evidenced that the representative students of the population have an adequate education regarding the importance of water consumption and verification of the expiration date of packaged products. In addition, they have adequate habits regarding the consumption of the first meal of the day and fruit. Likewise, it is concluded that the nutritional education received so far and their eating habits\u0000are mostly acceptable, but not outstanding. This implies that their knowledge of nutrition does not necessarily have a decisive influence on their eating practices. No great difference was found between the aforementioned careers regarding nutritional education received and eating habits.","PeriodicalId":21546,"journal":{"name":"Revista ECIPeru","volume":"161 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77499544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cachectic syndrome is characterized by progressive loss of body weight, anorexia, asthenia, immunosuppression and metabolism of carbohydrates, lipids and proteins, with loss of muscle and adipose tissue. It used dry cauliflower inflorescence extract (ESC) and male mice 35-45 g with induced cancer, divided into groups: G1 untreated control, G2 and G3 treated with ESC, doses 10 and 20mg/kg/bw/vo and G4 treated with quercitin, dose 7.14mg/Kg/bw/vo for 90 days. Some manifestations of cachectic syndrome were determined. It was observed that G1 had thinning and progressive increase in alopecia, asthenia and conjunctival xerosis due to energy and metabolic imbalance compared to G2, G3 and G4 that had higher body weight and fewer cachectic manifestations, being significant by time and treatment group (P<0.01). It has been reported that cauliflower contains flavonoids quercitin and kaemferol, with anti-inflammatory properties for its action on cyclooxygenase, lipooxygenase, interleukins and chemosins, with antioxidant properties on intracellular glutathione, in redox reactions and favoring the expression of caspases in cell apoptosis. Therefore, it is concluded that cauliflower prevents body weight loss and decreases cachectic syndrome because it contains kaempferol and quercitin that act synergistically with anti-inflammatory, antioxidant and anticancer properties.","PeriodicalId":21546,"journal":{"name":"Revista ECIPeru","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89193270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Para este propósito, tuvimos que determinar el área dedicada al cultivo de la caña de azúcar, la cantidad de caña de azúcar producida por cada área cultivada, la cantidad de bagazo obtenida de la caña de azúcar y la proporción de humedad y residuos secos, utilizando datos estadísticos peruanos. El modelo matemático de Prokash Roy se consideró modificando las constantes del equilibrio químico y las tasas de reacciones químicas que se controlan cinéticamente a velocidad finita, porque en realidad el sistema se comporta como un cuasi equilibrio. Para este modelo modificado, la humedad del bagazo debe ser inferior al 20% pero no debe estar completamente seca. Los resultados fueron validados con los datos experimentales de Jayah. Además, se utilizó una nueva codificación en el lenguaje de programación Python versión 3.x, utilizando una plataforma interactiva llamada Jupyter Notebook, que también hace posible predecir la composición, el máximo valor calorífico inferior del gas pobre y la temperatura de la zona pirooxidación. La estimación del potencial energético del gas pobre a partir de la gasificación del bagazo de la caña de azúcar fue de 19396.6 TJ por año como valor máximo y 16843.7 TJ por año como valor mínimo.\u0000\u0000Descriptores: Gasificación, potencial energético, gasificador de tiro descendente, residuos agrícolas.\u0000\u0000Abstract\u0000\u0000The purpose of this work is to estimate the energy potential of poor gas obtained from sugarcane bagasse gasification using downward-flow gasifiers in Peru through a new mathematical model that considers the size of biomass fragments. For this purpose, we had to determine the area dedicated to the cultivation of sugarcane, the amount of sugarcane produced by each cultivated area, the amount of bagasse obtained from sugarcane and the proportion of moisture and dry residue, using Peruvian statistical data. The mathematical model of Prokash Roy was considered by modifying the constants of chemical equilibrium and the rates of chemical reactions that are kinetically controlled at finite speed, because actually the system is behaving as a quasi-equilibrium. For this modified model, the humidity of the bagasse should be less than 20% but should not be completely dry.
