Authors: Arufe Giráldez Víctor , Pena García Alba , Navarro Patón Rubén
Published: September 2021

Los beneficios de la Educación Física en la niñez y adolescencia han sido abordados por múltiples investigadores. Sin embargo, en la infancia, etapa de 0 a 6 años, existen pocos trabajos que abordasen el estudio de los efectos producidos por programas de Educación Física estructurados. Este trabajo tiene como principal objetivo realizar una revisión sistemática sobre los principales trabajos de investigación que abordaron los efectos de programas de Educación Física en el desarrollo motor, cognitivo, social, afectivo-emocional y salud de niños de 0 a 6 años. Se ha seguido el protocolo PRISMA utilizándose un total de 5 bases de datos internacionales y nacionales (Web of Science, Scopus, Sport Discus, Psycinfo y Dialnet). Se obtuvieron un total de 1370 artículos potenciales, de los cuales 30 cumplieron los criterios de inclusión y exclusión. Todos ellos son estudios empíricos realizados en diferentes países. Los resultados confirman un mayor número de evidencias científicas centradas en el área del desarrollo cognitivo, seguida de la esfera motriz. Se han encontrado también diversos estudios que abordan mejoras en la salud de los niños, la esfera social, afectiva y emocional. Se concluye la necesidad de implementar más programas de Educación Física estructurados en la etapa de 0 a 6 años, a fin de favorecer el desarrollo de diferentes áreas de los niños y mejorar su salud. En ningún estudio se encontraron efectos negativos para su desarrollo. Por ello, se invita a las administraciones educativas a incorporar un mayor número de horas de Educación Física en la Educación Infantil.

Authors: De La Hoz Jhonathan
Published: September 2021

La eficiencia energética es una práctica que está enfocada a reducir el consumo energético mediante el uso racionalizado y óptimo de la energía eléctrica, su importancia en la actualidad se debe a que ha surgido como una respuesta a las problemáticas ambientales ocasionadas principalmente por la quema de combustibles fósiles utilizados para la producción de energía. Basándonos en este principio, se ha desarrollado un sistema de supervisión para ahorrar energía mediante la gestión energética, realizando control de las cargas mediante una red de sensores y estimación del posible consumo energético mediante la raspberry pi que actúa como consola central integrando los subsistemas (la plataforma virtual, la red de sensores y la conexión a internet). Los resultados que se han obtenido de la previa investigación y aplicando el método experimental son el desarrollo de un sistema capaz de evaluar la orden del usuario, en donde este expresa un aproximado del valor en pesos de su factura y dicho programa devuelve las horas destinadas para cada electrodoméstico; para esto, internamente, el sistema consulta la forma de cobro del gasto energético para calcular cuánto se debe consumir con el fin de llegar al monto deseado, teniendo en cuenta la jerarquización de algunos dispositivos por ser frecuentemente más utilizados, así como la sujeción de dispositivos de baja potencia y el uso de una tabla de consumo fijo en el que se ingresan los electrodomésticos que son de uso continuo. Finalmente, cabe resaltar que el éxito del sistema está vinculado con una firme cultura de ahorro y una red de cableado en óptimo estado.

Published: September 2021

This study uses a machine learning technique, a boosted tree model, to relate the student cognitive achievement in the 2018 data from the Programme of International Student Assessment (PISA) to other features related to the student learning process, capturing the complex and nonlinear relationships in the data. The SHapley Additive exPlanations (SHAP) approach is subsequently used to explain the complexity of the model. It reveals the relative importance of each of the features in predicting cognitive achievement. We find that instruction time comes out as an important predictor, but with a nonlinear relationship between its value and the contribution to the prediction. We find that a large weekly learning time of more than 35 hours is associated with less positive or even negative effect on the predicted outcome. We discuss how this method can possibly be used to signal problems in the student population related to learning time or other features.

There are many artifacts from various civilizations in our country, reaching day by day. Historical masonry structures are also among the structures that are considered cultural heritage. For this reason, detailed examination of these historical masonry structures, testing of the samples of this structure and documentation of this information obtained from these tests is a very important issue in terms of ensuring that these structures can be transmitted to future generations in a robust manner.
In this article, it is planned to examine the stones used in masonry structures with computerized vision technology. For this reason, stones with different qualities to be taken from quarries will be taken images primarily through a camera. Later on, the image of each sample will be transferred to the computer environment and the features belonging to these samples will be removed through image processing. Later on, these samples will be tested in the laboratory and their strengths will be measured. Consequently, the data attained from the laboratory environment and the results attained by image processing will be compared and the calibration of this proposed image processing based analysis method will be done. As a result of these studies, it will be possible to carry out experimental applications in the laboratory environment in computer environment. Again due to these studies very complex and lengthy studies can be significantly shortened; some characteristics of samples taken with a simple camera can be measured very quickly in a computer setting.

Published: September 2021

The aim of this research is to carry out the heat transfer analysis of PVT hybrid active solar still (HASS) at different water depth to obtain maximum output. Experimentation is performed for validation of thermal modeling with and without flowing water, having water depth of 0.15m in the solar still basin. During experimentation, water flows above the glass cover. Theoretically calculated values of basin water, basin liner, glass temperature and yield obtained using thermal modeling are very near to the experimental values having correlation coefficients 0.988, 0.981, 0.999 and 0.985 respectively. It is also found that thermal efficiency and daily exergy output increases by 4% and 8.2% respectively for this hybrid system whose glass cover is getting cooled by water flowing over it. Theoretical calculation for distillate output of the system was also calculated out for various climatic conditions of India using developed thermal modeling and it is found that proposed system gives higher annual yield of 2756.67 kg/m2 for the climate of Mumbai. The experimental uncertainty of the HASS is obtained as 14.82%.

Authors: Biradar Sneha , Teli Balakrishna , N. Prashanth V.
Published: September 2021

Background: Chronic obstructive pulmonary disease (COPD), the fourth leading cause of death in the world.Acute exacerbation of COPD has 10% mortality rate at admission and 1/3rd die within a year of hospitalization. Eosinopenia typically accompanies the response to acute inflammation or infection. The objective of this study was to know whether eosinopenia is an economical marker in predicting the outcome in patients hospitalized due to acute exacerbation of COPD.Methods: This is a prospective study conducted on 121 patients presenting with AECOPD satisfying inclusion and exclusion criteria admitted in hospitals attached to Bangalore Medical College and Research Institute. All necessary investigations were done. Patients with AECOPD were divided in two groups: One with eosinopenia and other without eosinopenia. Duration of hospitalization, need for mechanical ventilation and in-hospital mortality was assessed in both the groups.  Results: Among 121 patients with AECOPD, 56 were eosinopenic and 65 patients were non-eosinopenic. Majority of patients belonged to age group of 51-60 years with mean age was 62.06±10.783 years. Duration of hospitalization of patients with eosinopenia was 9.04±5.18 days and that of patients without eosinopenia was 6.15±2.89 (p value<0.001). Among them, 41 (73.2%) patients with eosinopenia and 21 (32.3%) patients without eosinopenia needed mechanical ventilation (p≤0.001). In-hospital mortality rates among eosinopenic and non-eosinopenic patients were 53.6% and 15.4% respectively.  Conclusions: There is a significant relationship between eosinopenia and outcomes of patients with AECOPD. Thus, eosinopenia is a useful, easy-to-measure, inexpensive biomarker for predicting the prognosis and outcome in patients with AECOPD.

O movimento nacionalista industrializante no Brasil (1830 – 1930): uma análise a partir dos estudos de Nícia Vilela Luz
Authors: Izepão Rosalina Lima , Giorno Débora
Published: September 2021

Quando se trata da indústria brasileira, são inúmeros os estudos publicados no país. A industrialização nacional ocorreu num processo lento e gradual, fruto de muitas disputas e acordos entre os vários grupos de interesses agrários e industriais desde a fase colonial, passando pela imperial até o final da primeira fase republicana, em 1930, quando este setor econômico começou, efetivamente, desabrochar. Considerando-se o exposto, no presente artigo tem-se como objetivo analisar o movimento nacionalista industrialista que se desenvolveu no Brasil, no período de 1830 a 1930, apresentado nos estudos de Nícia Vilela Luz. Metodologicamente, tratou-se de uma pesquisa que pode ser caracterizada, por seus objetivos, como bibliográfico-descritiva. Apesar de o Brasil ter sido uma economia agrário-exportadora até 1930, os resultados deste estudo mostraram que sempre existiram no país, mesmo na sua fase colonial-mercantil, pessoas e grupos defensores da execução de políticas governamentais direcionadas ao desenvolvimento industrial. O fortalecimento deste movimento se deu a partir de 1875, em razão da crise agrária e suas consequências. Ao longo deste período se destacaram, nesta luta, pessoas como: Joaquim José Rodrigues, Antônio Felício dos Santos, Aristides de Queiroz, Serzedelo Correa, Amaro Cavalcanti e Roberto Simonsen. As políticas e ações desenvolvidas, para o protecionismo industrial, mais utilizadas na época foram tarifas alfandegárias, subsídios a determinados setores, além do uso do capital estrangeiro.

O objetivo deste artigo é identificar o nível de sustentabilidade do município de Passo Fundo/RS, em relação aos demais municípios do Corede Produção. Trata-se de uma pesquisa aplicada, baseada na utilização do Índice de Desenvolvimento Sustentável para Municípios (IDSM), metodologia proposta por Martins e Cândido (2008) para mensurar o nível de sustentabilidade adaptada para os municípios. Os dados dos indicadores referentes aos municípios foram obtidos nas principais bases de dados e portais institucionais – IBGE, Ministério da Educação, Atlas do Desenvolvimento Humano, Portal da Transparência, FEE, DATASUS, TRE, TCE, SNIS e IPEADATA, pesquisados no ano de 2017. Os resultados obtidos apontam que o município de Passo Fundo apresenta nível aceitável de sustentabilidade, conforme os parâmetros utilizados no método. Este índice é obtido, sobretudo, pelo desempenho ideal/aceitável das dimensões cultural e político-institucional, no entanto, alguns indicadores apresentaram índice crítico como uso da terra, ou em alerta, os indicadores de dinâmica populacional e emprego e renda, que são fundamentais para o desenvolvimento sustentável. Para estudos futuros sugere-se aplicar o Índice de Desenvolvimento Local Sustentável, que incorpora a participação de atores sociais na priorização de questões do desenvolvimento local. Ainda, a pesquisa gerou um banco de dados que proporciona identificar o IDSM para todos os municípios do Corede Produção, assim como o estudo do nível de sustentabilidade para a Região da Produção.Palavras-chave: desenvolvimento local, idsm, indicadores, sustentabilidade.
Gênero, Insituições e economia: uma visão feminista no mercado de trabalho
Authors: Mota Emily Santos , Da Silva Igor Castellano
Published: September 2021

Perante à discussão sobre gênero no mercado de trabalho, os anos de 1970 foi um marco para o movimento feminista e para o processo de reestruturação produtiva. Após o período industrial, os questionamentos sobre as formas de se analisar os processos econômicos e até mesmo a própria economia passaram a ser questionados. Diante desses questionamentos e dúvidas surge a economia feminista, criticando o mainstream econômico por analisar os processos sem considerar os fatores históricos, psicológicos, experiências vividas, e hábitos construídos socialmente que determinam os processos decisórios individuais. As Instituições, dentro da sua pluralidade de definições, podem surgir tanto como organizações governamentais possivelmente atuantes de maneira formal por meio de normas e regulamentos de atividades, como também informalmente através de arranjos moldadores de comportamentos, pensamentos, cultura, hábitos e tabus em contextos coletivos e individuais. O artigo será dividido, além dessa introdução, Instituições e economia, a discussão do gênero como uma Instituição social, gênero e patriarcado, a discussão da economia do trabalho do ponto de vista feminista (abordando o ponto de vista institucional).

In the areas of electronic identification and electronic trust services, the Regulation No. 910/2014 of the European Parliament and of the Council on electronic identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC (eIDAS) creates uniform regulations for electronic signatures, seals, time stamps, registered mail and website certificates in the European single market. All developments that affect the security of signature procedures have an impact. In this study, we consider the candidates for quantum computer-resistant asymmetric cryptographic (PQC) methods currently under investigation in international research and standardization and evaluate their suitability for PKI systems with a focus on long-term preservation of evidential value, as is the case in particular with eIDAS-compliant signature solutions. Based on an evaluation system proposed by us - an adaptation of the system from [2] - we compare the application requirements with the properties of the candidates and recommend suitable methods.

Published: September 2021

The performance of a solar energy-assisted seed storage room was evaluated through an ordinary 22-m3 room that was retrofitted with a solar collector, inlets and chimney. The structure was made of a solar collector to heat the ambient air before entering the chimney. The chimney circulated the air inside the structure and inlets. To compare the performance of the modified storage room, a room with a similar capacity and without the retrofitted components (control storage room) was used. Twelve 8 kg bags of maize were stored in each storage room for a period of three months. Samples were taken every two weeks to determine germination rate, moisture content and seed vigour. The temperature and relative humidity (RH) was measured during storage. The RH in the control storage was significantly higher (P≤0.05) (60.6 ± 5.87%) than in the modified storage (40.1 ± 3.21%) during the day. However, at night, the RH in the control storage room was significantly lower (P≤0.05) (58.5 ± 7.32%) than in the modified storage (63.7 ± 6.28%). The RH in the modified storage room increased from 40.1% during the day to 63.7% at night. The RH in the control storage room decreased slightly from 60.6% to 58.5% during the day and night. The seed moisture content in the modified storage facility was significantly lower (P≤0.05) (12.6 ± 0.21%) than in the control storage room (13.3 ± 0.52%). The moisture content in the modified storage room decreased from 12.6% to 12.4%, whereas in the control room, moisture content increased from 12.6% to 13.8% in three months. The seed germination rate obtained after three months of storage in the modified storage room was significantly higher (P≤0.05) (98.5 ± 0.85%) than in the control storage room (96.8 ± 1.49%).The seed vigour obtained in the modified storage room was significantly higher (93.6 ± 0.35%) than in the control room (91.7 ± 2.08%) (P≤0.05). Seed stored in the control storage lost vigour at a faster rate, compared to the seeds stored in the modified storage room. Therefore, the modified naturally-ventilated seed storage room maintained seed quality better than the control storage room.

This study aimed at determining the nutritional status of under-five children or pupils in Benue State. The objective of the study was to assess the prevalence of stunting, wasting and BMI for age of under-five children or pupils in Benue State. The participants for this study were three hundred and forty (340) under-five children or pupils who were sampled from the Early Childcare Centres (ECCs) across the primary schools in selected Local Government Areas of Benue State using multistage sampling technique consisting of three rural local government areas and three urban local government areas. Participants’ stature and body mass were measured in accordance with the protocol of the International Society for the Advancement of Kinanthropometry. The body Mass Index (BMI) of the participants was derived as a ratio of weight (in kilograms) to height (in meters) squared (kg/m2) and was expressed in standard deviation unit. The frequency and percentages were adopted in analyzing the prevalence of stunting, wasting and BMI. The WHO Anthroplus Software (version 3.2.2) was used to compute the under-five nutritional status which was categorized based on WHO recommendations. The results of the study indicated that, the overall prevalence of stunting and wasting were 44% and 7.6% respectively. The overall prevalence of underweight, overweight and obesity were 6.5%, 12.1% and 25.9%, respectively. The prevalence of stunted under-five children or children was more among rural children (49.5%) than their urban counterparts (38.2%). The prevalence of wasting among urban children (7.9%) was slightly higher than their rural counterparts (7.4%), though not significant. The prevalence of each of underweight, overweight and obesity was higher among urban children 7.9%, 13.8% and 27.1% than their rural counterparts which have the corresponding values of 5.3%, 10.6% and 24.3%, respectively. It was therefore recommended that health personnel especially in Benue State should create awareness through seminars and workshops in schools, health facilities and the media on the need to provide whole meals to children and discourage the consumption of snacks or processed foods by not making it part of the children’s lunch pack.

ТЕПЛООБМЕН ПРИ ФИЛЬТРАЦИИ ЖИДКОСТИ В КОЛЬЦЕВОМ КАНАЛЕ, ЗАПОЛНЕННОМ ПОРИСТОЙ СРЕДОЙ
Authors: Дехтярь Руслан Анатольевич
Published: September 2021

Актуальность работы обусловлена широким использованием пористых сред как при проектировании и оптимизации компактных теплообменников, так и в инженерных расчётах характеристик тепломассообмена в каналах с зернистой средой и при обтекании тел, погруженных в пористую среду. Цель: экспериментальное исследование процесса переноса тепла от стенки кольцевого канала к фильтрующейся через пористую вставку жидкости при различных режимах течения; получение полуэмпирических корреляций для теплообмена в инерционном режиме фильтрации жидкости в кольцевом канале. Объект: кольцевой канал с пористой вставкой, состоящей из стеклянных шариков одного диаметра с разными типами как регулярных, так и хаотических упаковок. Методы: экспериментальные методы поиска закономерностей процессов теплообмена. В опытах с помощью термопар измерялась температура обогреваемой внешней стенки кольцевого канала в четырех сечениях и температура нагревателя в двух разных точках. Также измерялись температуры на входе в рабочий участок и на выходе из него. Одновременно с тепловыми исследованиями измерялся расход жидкости при фильтрации через пористую вставку. Пористость определялась обычным весовым способом. В специальных тарировочных опытах отдельно определялись тепловые потери рабочего участка. Расчет коэффициента теплоотдачи проводился по подводимому потоку тепла к наружной стенке кольцевого канала с учетом тепловых потерь и по разности измеряемой температуры стенки и среднемассовой температуры жидкости в данном сечении. Результаты. Представлены результаты экспериментального исследования теплообмена фильтрационного потока жидкости со стенками кольцевого канала, заполненного пористой средой, при постоянном тепловом потоке на внешней стенке. Исследование проводилось на кольцевых каналах с различной шириной. По ширине канала укладывался или один слой шаров одного диаметра с двумя типами упаковок: кубической и ромбоэдрической, или несколько слоев шаров, но уже с произвольной упаковкой (от 3 до 10 шаров по ширине канала). При обработке экспериментальных данных в качестве определяющего геометрического параметра выбран гидравлический диаметр зерна. Показано, что в зависимости от режима фильтрации через пористую вставку существуют различные законы теплообмена. Так, для турбулентного режима фильтрации полученные данные для теплообмена хорошо обобщаются универсальным «законом двух третей». Приведено сравнение с данными других авторов для теплообмена в кольцевом канале и в круглой трубе. Показано, что в инерционном режиме фильтрации теплообмен соответствует закономерности Nu~Re1/2.

Background: Foxtail millet is one of the nutri-cereal foods for the people of semi arid regions. Proper nutrient management and source-sink alteration are major keys for achieving higher productivity in millets. However, potassium is not recommended to foxtail millet and the potential yield is not exploited. And also the study of source-sink alteration in foxtail millet by using plant growth regulators is meager. Methods: An experiment was conducted to study the impact of plant growth retardants viz., chlormequat chloride (CCC) and mepiquat chloride (MC) with the nutrient potassium (K2SO4 - 1%) on growth, gas exchange parameters and grain yield of foxtail millet under rainfed condition. Plant growth retardants with potassium consortium were used as foliar spray at flower initiation stage under field condition. Standard methods were used to measure the plant height, root length, number of leaves, LAD, CGR and grain yield. The photosynthetic rate, transpiration rate and leaf temperature were measured by using the instrument PPS. Result: Foliar spray of CCC (250 ppm) with 1% K2SO4 showed supremacy to enhance crop growth rate, leaf area duration, photosynthetic rate, transpiration rate and grain yield compared to other treatments. However, lowest plant height (100.7 cm) and number of leaves were observed by CCC (250 ppm) alone. Highest photosynthetic rate (26.84) and transpiration rate (17.94) were registered by CCC + K2SO4. Lowest leaf temperature of 34.1ºC was registered by 1% K2SO4 compared to control (35.6°C). CCC with K2SO4 recorded highest LAD value of 46.1 which is on par with K2SO4 alone (45.9). CCC with K2SO4 registered highest grain yield of 2.13 t ha-1 with increased yield of 18.3% over control. However, highest benefit cost ratio of ratio of 2.75 was recorded by 1% K2SO4 alone.

A construção de práticas educacionais inclusivas se configura como um dos principais desafios inerentes ao cenário educacional brasileiro, pois, pressupõe o desenvolvimento de práticas de ensino e aprendizagem para todos, a partir do respeito às especificidades e as diferenças de cada estudante. Assim, o paradigma educacional brasileiro tem passado por importantes reconfigurações, uma vez que a sociedade contemporânea tenta direcionar suas ações ao ideal de superação de desigualdades e desenvolvimento pleno do ser humano em todas as suas dimensões. Diante disso, a inclusão escolar se configura como um direito de todos os estudantes, em todos os níveis e modalidade de ensino, inclusive na Educação a Distância (EaD). Nessa perspectiva, é muito importante que os profissionais que desempenham o papel de mediadores pedagógicos, estejam atentos à importância em desenvolverem por meio de suas práticas, um trabalho que atenda às especificidades de todos os estudantes, acrescido a uma diversidade de recursos e condições que possibilitem, de fato, que todos possam aprender e participar equanimemente e com qualidade do processo educativo. Posto isto, com base na abordagem metodológica qualitativa, realizada por meio de uma pesquisa bibliográfica, o presente trabalho teve por objetivo refletir e analisar o papel do tutor no contexto da educação a distância, frente aos princípios de uma educação inclusiva.Palavras-chave: Inclusão. Mediação Pedagógica. Acessibilidade. Educação a Distância. Ambientes Virtuais de Aprendizagem.
THE CLASS OBSERVERS AND THEIR SUBJECT POSITION (S) IN THE ELT FIELD
Authors: Martínez Luengas Miguel
Published: September 2021

Las observaciones de clase son prácticas constantes llevadas a cabo en el campo del ELT (Enseñanza del idioma inglés). Cuando una persona comienza a estudiar para ser profesor de inglés, esta persona observa los contextos escolares, observa los profesores en los colegios / universidades y también esa persona es observada por el profesor y / o coordinadores. De la misma manera, la observación se utiliza para evaluar los procesos pedagógicos / académicos, se utiliza para retroalimentar, para recoger información en procesos de investigación, entre otros. Sin embargo, hay algunas preguntas relevantes sobre este tema, por ejemplo, ¿quién está observando las clases? ¿para qué se observa? ¿Existen diferentes posiciones del observador?

Este artículo pretende indagar sobre los aspectos desconocidos detrás de las observaciones de clases de inglés y principalmente, explorar las posiciones de los observadores (sujetos que circulan en esta práctica). Estas posiciones están en constante movimiento y poseen voces, emociones, luchas, deseos y más características dentro de los observadores de la clase en el campo del ELT. El propósito de este texto tiene que ver con la aparición de las diversas posiciones del sujeto observador en el campo del ELT.

Published: September 2021

Este artículo tiene por objeto definir una didáctica de la escritura creativa basada en la conceptualización epistémica de la didáctica general y la delimitación de su objeto de estudio. Entendiendo, que enseñar escritura creativa exige al docente convertirse en un agente de contagio, conocer la literatura, los procesos de producción escrita y las reglas formales de la lengua. Además, como proceso creativo, permite el desarrollo del pensamiento del estudiante, sujeto activo y autónomo que construye y aporta a su aprendizaje, uno que trascienda las fórmulas de producción, incentivando el desarrollo de una voz propia y representando el territorio.
CONECTORES Y ANÁLISIS INFERENCIAL EN BÁSICA PRIMARIA
Authors: Pestana Velandia Lisbeth Nataly , Martínez Ferro Hernán
Published: September 2021

La inferencia es un proceso lógico-cognitivo que permite llegar a una proposición teniendo en cuenta como base inicial, otras proposiciones dadas. Por tanto, permite crear relaciones o conexiones entre los significados en un conjunto de proposiciones. La lectura inferencial es un momento imprescindible del proceso que conduce a la lectura crítica, al punto que se puede afirmar que sin lectura inferencial no se puede hacer lectura crítica. Teniendo en cuenta el anterior postulado, esta investigación se centró en fortalecer el análisis inferencial, a partir del uso de conectores discursivos en textos argumentativos, con niños de grado tercero. Para ello se escogieron tres conectores del discurso: “porque”, “sin embargo” y “además”. Con ellos se pretendió que el estudiante se familiarizara y entendiera el sentido de cada uno, y al usarlos adecuadamente, les permitiera entender la estructura de un argumento y fácilmente identificar las funciones que cumplen las premisas y las conclusiones dentro del mismo. Se implementó una propuesta bajo el paradigma interpretativo con un enfoque mixto de investigación, a través de la aplicación de unidades didácticas. Los resultados evidenciaron un mayor empleo de los conectores como guía para realizar inferencias, así mismo facilitaron la identificación de premisas y conclusiones, llevando a la creación de argumentos propios con relación lógica.

La presente investigación, desarrollará la interacción dinámica suelo estructura IDSE con y sin amortiguamiento aplicado a 3 modelos denominados modelo A, modelo B y modelo C con 4, 8 y 12 pisos respectivamente. Estos modelos serán evaluados en tres tipos de perfiles de suelo S1, S2 y S3 con características (peso específico, coeficiente de poisson y carga admisible) obtenidas de los libros del Sr. Braja M. Das y Willian Rodriguez Serquen. La evaluación de la IDSE se realizará mediante las ecuaciones simplificadas propuestas por la Norma Americana (EEUU) NIST GCR 12-917-21 Soil-Structure Interaction for Building Structures donde se desarrolla la interacción inercial que se hace referencia a los desplazamientos y rotaciones en la base de la estructura (fundación) debido a la respuesta de la estructura cuando da lugar un sismo. Asimismo, la flexibilidad de la fundación y suelo son representados mediante 6 rigideces (3 de traslacionales y 3 de rotación) con y sin amortiguamiento. Para cada modelo se realizará una comparación de cortante basal, momento, desplazamientos, derivas, periodos, frecuencias, modos de vibración, fuerzas internas máximas, y fuerzas internas en un pórtico con la finalidad de observar el comportamiento de las estructuras en los distintos tipos de suelo y tamaños de las modelos propuestas.

Authors:   , Scerpella Crespo Jimena
Published: September 2021

La presente investigación tuvo como objetivo analizar la relación entre la calidad de las relaciones con pares y la insatisfacción con la imagen corporal en una muestra de adolescentes mujeres de una institución educativa privada de Lima Metropolitana. Las participantes fueron 191 adolescentes mujeres entre 13 y 17 años (M = 14.95, DE = 1.16). Se utilizó el Quality of Relationships Inventory (QRI) para medir la calidad de las relaciones entre pares y dos instrumentos para medir la insatisfacción con la imagen corporal: el Contour Drawing Rating Scale (CDRS) y una medida de ítem único de imagen corporal. El análisis de los resultados determinó que existe correlación negativa y de magnitud baja entre la dimensión de soporte y la insatisfacción con la imagen corporal (r = -.16, p < .05). Asimismo, se halló una correlación positiva, significativa y de magnitud moderada entre la insatisfacción con la imagen corporal y el índice de masa corporal (IMC) de las participantes (r = .36, p < .01).
