Hábitos alimenticios para mejorar su calidad de vida

This research is oriented to determine the influence level that food habits have on the children quality life at fifth and sixth years of Basic General Education at Victoria Vásconez Cuvi Elementary School. The nutrition and eating habits advantages and disadvantages. It has been shown that there is a greater lack of knowledge about eating habits in students, which leads to a lack of motivation when performing school tasks, insufficient academic performance, poor behavior, and inadequate nutrition that children receive in their daily lives. To know more about this problem a theoretical and technical support was used together with a by bibliographic sources review as well as the survey application to teachers and students who provided valuable and useful information for the educational institution, teachers and students benefit, in the same way when tabulating the data was observed that students do not know about nutrition are aware and must feed themselves to be healthy….El proyecto está orientado a determinar el grado de influencia que tiene los hábitos alimenticios en la calidad de vida de los niños y niñas de los quintos y sextos años de Educación General Básica de la Unidad Educativa Victoria Vásconez Cuvi, además se hizo un análisis exhaustivo sobre las ventajas y las desventajas de nutrición y hábitos de alimentación. Se ha demostrado que existe desconocimiento mayor en los estudiantes sobre los hábitos alimenticios lo cual ocasiona una desmotivación al realizar sus tareas escolares, insuficiente rendimiento académico, mal comportamiento, por la inadecuada alimentación que los niños y niñas reciben el su diario vivir. Para conocer más a fondo esta problemática se recurrió a un sustento teórico técnico, conjuntamente a una revisión profunda y minuciosa de fuentes bibliográficas así como también a la aplicación de una encuesta a docentes y estudiantes los mismos que arrojaron información valiosa y de utilidad para el beneficio de la institución educativa, docentes y estudiantes…

A 1.2 V Low-Noise-Amplifier with Double Feedback for High Gain and Low Noise Figure

Part 19: Electronics: AmplifiersInternational audienceIn this paper we present a balun low noise amplifier (LNA) in which the gain is boosted using a double feedback structure. The circuit is based in a conventional Balun LNA with noise and distortion cancellation. The LNA is based in two basic stages: common-gate (CG) and common-source (CS). We propose to replace the resistors by active loads, which have two inputs that will be used to provide the feedback (in the CG and CS stages). This proposed methodology will boost the gain and reduce the NF. Simulation results, with a 130 nm CMOS technology, show that the gain is 23.8 dB and the NF is less than 1.8 dB. The total power dissipation is only 5.3(since no extra blocks are required), leading to an FOM of 5.7 mW− 1 from a nominal 1.2 supply

Cuentos de nunca acabar. Aproximaciones desde la interculturalidad

Cuentos de nunca acabar. Aproximaciones desde la interculturalidad, surge después de la pandemia y su imposibilidad de socializar “en persona” con los compañeros de eventuales encuentros, porque la Comprensión Lectora tenía que reinventarse para su nueva reflexión cognitiva, adaptación contextual y reconstrucción del conocimiento. Este renovado enfoque de la realidad postpandemia, concebido en el marco de la educación intercultural comunitaria, busca potencializar los entornos naturales, sociales y culturales como recursos de aprendizaje multidisciplinario a través del lenguaje animado de los cuentos. En este marco, había que dinamizar la asignatura de Comunicación Oral y Escrita, que se dicta en los Primeros Niveles de los Centros de Apoyo de Otavalo, Cayambe, Latacunga y Riobamba, mediante un eje transversal donde los estudiantes escriban fundamentados en valores de la cosmovisión andina, considerando que provienen de varios lugares de la sierra y amazonía ecuatoriana. Todo surgió del encuentro presencial de un sábado cualquiera donde los estudiantes realizaban ejercicios narrativos, logrando una apreciable respuesta de imaginación, más emotiva que la clásica tarea de las Unidades, tanto así que, pasados unos días, seguían llegando sus escritos a mi correo. Entonces nos pusimos manos a la obra, cada estudiante tendría dos opciones como Actividad Integradora, la primera consistía en escribir un cuento de su propia inspiración, y la segunda analizar un clásico para comentar sus valores y antivalores. La mayor parte de estudiantes decidió escribir su propio cuento, de donde se escogieron algunas participaciones que podrían considerarse originales, para una edición que, respetando la transcripción de la tradición oral que prima en los sectores comunitarios, nos concretamos en revisar la puntuación y ortografía para publicarlos. Con esto buscamos innovar la Actividad Integradora, por algo más práctico y operativo para configurar los Objetos de Aprendizaje que buscamos. Así nació, en medio del camino, este libro de Cuentos de nunca acabar. Aproximaciones desde la interculturalidad, que ponemos en sus manos. Hernán Hermosa Mantilla Quito, junio de 202

Flexible Collective Housing: A housing alternative to mitigate volcanic risks in Los Chillos Valley.

planos, ilustraciones.El proyecto de Vivienda Colectiva propone una alternativa habitacional diseñada para optimizar el uso del espacio y fomentar la convivencia comunitaria en el Valle de Los Chillos, una zona parcialmente expuesta a riesgos volcánicos debido a su proximidad al Volcán Cotopaxi. Se busca implantar el proyecto en un entorno de bajo riesgo “el lugar”, para minimizar la vulnerabilidad a las consecuencias de posibles lahares o evento natural relacionado, promoviendo la preparación y posible autonomía de recursos en caso de emergencias, se crean espacios flexibles y adaptativos que respondan a las necesidades cambiantes de los residentes. Desde una perspectiva arquitectónica, se integran estrategias específicas, comenzando con el análisis para la selección de un lote en un área de bajo riesgo, priorizando su orientación y los frentes hacia dos calles públicas, para maximizar la integración urbana. Se proyectan espacios comunales que sirven como zonas de interacción social y sirven como lugares seguros durante situaciones de emergencia, utilizando materiales resistentes a fenómenos naturales como sismos y ceniza volcánica. La flexibilidad espacial se logra a través de una retícula de habitaciones modulares, basada en el modelo de MAIO Studio, que permite la reconfiguración según las necesidades de los habitantes, promoviendo la eficiencia del espacio. El proyecto se compone de dos bloques simétricos longitudinalmente, integrados por una secuencia espacial en planta baja que incluye espacios verdes, huertos y áreas de recreación. Esta propuesta busca representar una alternativa de vivienda que promueva el bienestar y la seguridad de los habitantes. Concluyendo que, la evaluación del riesgo, en lugar de centrarse solo en desastres pasados, se enfoca en prevenir y mitigar impactos negativos, por lo cual, derivan los objetivos de este proyecto, asegurando que la mitigación implica estrategias preventivas antes, durante y después de un evento natural o catastrófico.The Collective Housing project proposes a housing alternative designed to optimize the use of space and promote community coexistence in Los Chillos Valley, an area partially exposed to volcanic risks due to its proximity to the Cotopaxi Volcano. The project seeks to implement the project in a low-risk environment "the place", to minimize vulnerability to the consequences of possible lahars or related natural events, promoting preparedness and possible autonomy of resources in case of emergencies, creating flexible and adaptive spaces that respond to the changing needs of residents. From an architectural perspective, specific strategies are integrated, starting with the analysis for the selection of a lot in a low-risk area, prioritizing its orientation and fronts towards two public streets, to maximize urban integration. Communal spaces are planned to serve as social interaction zones and serve as safe places during emergency situations, using materials resistant to natural phenomena such as earthquakes and volcanic ash. Spatial flexibility is achieved through a grid of modular rooms, based on the MAIO Studio model, which allows for reconfiguration according to the needs of the inhabitants, promoting space efficiency. The project consists of two longitudinally symmetrical blocks, integrated by a spatial sequence on the ground floor that includes green spaces, gardens and recreational areas. This proposal seeks to represent a housing alternative that promotes the well-being and safety of the inhabitants. Concluding that risk assessment, instead of focusing only on past disasters, focuses on preventing and mitigating negative impacts, thus deriving the objectives of this project, ensuring that mitigation involves preventive strategies before, during and after a natural or catastrophic event.PregradoArquitect

Quantifying and mapping soil organic carbon in Mali, West Africa using spatiotemporal methods

Thesis (Ph.D.)--University of Hawaii at Manoa, 2008.The Kyoto protocol recognized the importance of the terrestrial sink of carbon and proposed schemes that allow countries to treat sequestered carbon as a commodity that can be traded for global environmental benefit. Carbon sequestration can be a win-win scenario because it also introduces a set of new benefits into dryland farming communities particularly in Sub-Saharan Africa. The possibility, however, for agricultural producers to participate in the emerging market for tradable carbon-credits requires a reliable verification mechanism. Soil carbon inventories of many developing nations rely on a broad scale assessment. These approaches do not account for the spatial and temporal variability of soil carbon nor do they provide a measure of uncertainty associated with these assessments. This study proposed the use of Bayesian Maximum Entropy (BME) to quantify and map soil organic carbon at field scale in four agroecological zones of Mali, Sub-Saharan Africa. The prediction model comparisons using the mean error (ME) indicated that BME performed better than did the kriging methods (0.033, 0.41, respectively). BME prediction also provided a lower MSE representing a 25% reduction compared with Kriging, and 10% compared with cokriging. This study also demonstrated potential use of space---time covariances as tools to improve our understanding of spatial and temporal variability of soil organic carbon. Based on the temporal and spatial models maps were generated to predict mean trends. The estimation of tree biomass in Sub-Saharan Africa is important for an accurate assessment of the potential of these systems to capture and store carbon. The results show that tree carbon represented as much as 34% of the amount of organic carbon stored in soil surface (0-20 cm). Data from 2000 to 2006 indicated a net increase of soil organic carbon, which varied between 2.6 to 13.9 Mg ha-1. Despite the complexities that characterize the spatial and temporal distribution of most environmental processes, BME provides a framework to analyze both space and time components.Includes bibliographical references (leaves 187-208).Also available by subscription via World Wide Web208 leaves, bound 29 c

Lexical restructuring in the absence of literacy.

Vocabulary growth was suggested to prompt the implementation of increasingly finer-grained lexical representations of spoken words in children (e.g. [Metsala, J. L. & Walley, A. C. (1998). Spoken vocabulary growth and the segmental restructuring of lexical representations: precursors to phonemic awareness and early reading ability. In J. L. Metsala & L. C. Ehri (Eds.), Word recognition in beginning literacy (pp. 89-120). Hillsdale, NJ: Erlbaum.]). Although literacy was not explicitly mentioned in this lexical restructuring hypothesis, the process of learning to read and spell might also have a significant impact on the specification of lexical representations (e.g. [Carroll, J. M. & Snowling, M. J. (2001). The effects of global similarity between stimuli on children's judgments of rime and alliteration. Applied Psycholinguistics, 22, 327-342.]; [Goswami, U. (2000). Phonological representations, reading development and dyslexia: Towards a cross-linguistic theoretical framework. Dyslexia, 6, 133-151.]). This is what we checked in the present study. We manipulated word frequency and neighborhood density in a gating task (Experiment 1) and a word-identification-in-noise task (Experiment 2) presented to Portuguese literate and illiterate adults. Ex-illiterates were also tested in Experiment 2 in order to disentangle the effects of vocabulary size and literacy. There was an interaction between word frequency and neighborhood density, which was similar in the three groups. These did not differ even for the words that are supposed to undergo lexical restructuring the latest (low frequency words from sparse neighborhoods). Thus, segmental lexical representations seem to develop independently of literacy. While segmental restructuring is not affected by literacy, it constrains the development of phoneme awareness as shown by the fact that, in Experiment 3, neighborhood density modulated the phoneme deletion performance of both illiterates and ex-illiterates.Journal ArticleResearch Support, Non-U.S. Gov'tSCOPUS: ar.jinfo:eu-repo/semantics/publishe

Does math education modify the approximate number system? A comparison of schooled and unschooled adults

Does math education contribute to refine the phylogenetically inherited capacity to approximately process large numbers? The question was examined in Western adults with different levels of math education. Unschooled adults who never received math education were compared to unschooled-instructed adults who did not attend regular school but received math education in adulthood, and to schooled adults who attended regular school in childhood. In the number-comparison task (Exp. 1), the unschooled group was slower and made more errors than the other groups both when numerical symbols and nonsymbolic dot collections were presented. In the forced-choice mapping task (Exp. 2), the unschooled group experienced more difficulty than the others in linking large nonsymbolic and symbolic quantities, as well as in matching purely nonsymbolic quantities. These results suggest that Western adults who did not receive math education have less precise approximate number skills than adults who acquired exact number competences through math education.info:eu-repo/semantics/publishe
