El Derecho a la Consulta y al Consentimiento Previo, Libre e Informado
Authors: Zamora-Vázquez Ana Fabiola , Ormaza-Ávila Diego Adrián
Published: September 2019

Este trabajo de investigación tiene como objetivo exponer los aspectos fundamentales del derecho a la consulta previa de los pueblos indígenas, desde diversas perspectivas dentro del Ecuador y del derecho internacional, estudiar cómo se ha reconocido este derecho y como incluye a los pueblos indígenas y tribales en la toma de decisiones por parte del Estado. Cualquier situación en la actualidad que se encuentre relacionada con los derechos de los pueblos indígenas en América de manera necesaria pasa por el sistema interamericano de derechos humanos, debido a las transgresiones de derechos individuales que han sufrido y que hoy las consagran en las Constituciones de cada país como en Convención Americana, que debe encargarse con absoluta responsabilidad de la protección de los derechos de los pueblos indígenas. Uno de los deberes primordiales que tiene cada Estado es de proteger y garantizar el ejercicio efectivo de los derechos fundamentales, por ende, está institución se encuentra enmarcada dentro de la propuesta de estado constitucional de derechos y justicia, que trata de forma o como eje transversal los derechos de la naturaleza, el medio ambiente, la participación social que tiene un gran interés en lo que respecta al análisis sobre uno de los mecanismos de participación de mayor relevancia, como lo es la consulta previa. Los países deben ser respetuosos de la diversidad, la consulta previa debe ser aplicada antes de realizar actividades que puedan afectar sus intereses y derechos colectivos, ya que los pueblos indígenas deben sentir su identificación como descendientes históricos que mantienen sus costumbres y tradiciones. La consulta previa se realiza a toda la comunidad, la misma que debe ser realizada por el estado, cuando algunas de sus medidas puedan afectar los derechos de las comunidades campesinas.

Authors: De-Agostini-Solines Giancarlo Giorgio , Viteri Frank , Yamba-Yugsi Marco
Published: September 2019

A lo largo del presente trabajo, se hace un análisis de los procesos educativos a distancia desde la contextualización de dichos procesos, con el fin de atender a las necesidades de las personas beneficiarias, pero también analizar las categorías de calidad, justicia social y pertinencia en el sistema de educación a distancia, lo cual va a evitar la homogeneización la educación a distancia, ya que de hacerlo, no podrá atender a todos los grupos vulnerables y excluidos.
El llamado es repensar estos procesos educativos, no como una extensión del sistema formal - presencial, sino como una modalidad independiente que responde a las necesidades contextualizadas.  Y que aunque se haga uso de categorías de la educación presencial, estas deben ser adecuadas a las particularidades de la población a la que se dirige, caso contrario, se constituiría en un margen de la educación presencial.

Published: September 2019

En la parroquia de Cangahua, existe un turismo incipiente. Los factores incidentes en este problema son el desconocimiento del potencial turístico del territorio, los productos y servicios deficientes, la concentración de actividades económicas en agricultura y ganadería, y la poca gestión de instituciones públicas inherentes al territorio. Esta situación tiene como efectos la escasa diversificación de alternativas productivas y económicas, la subutilización de recursos, el poco aprovechamiento de los atractivos naturales y culturales, así como el escaso posicionamiento de los emprendimientos turísticos, hoteleros y gastronómicos. Como una alternativa de solución a este problema, la Universidad (``"UTE'') presentó el proyecto de vinculación con la sociedad ``Propuesta de desarrollo turístico sostenible en la parroquia de Cangahua'', en el que la Dirección de Vinculación con la Sociedad y las Facultades de Hospitalidad y Servicios, Comunicación, Artes y Humanidades, y Arquitectura y Urbanismo se encuentran trabajando con miras al desarrollo local. En tal sentido, la presente investigación, hace referencia a aspectos del proyecto que tienen que ver con el desarrollo integral de la comunidad, el mejoramiento de la calidad de vida y la participación comunitaria e institucional dentro del desarrollo de capacidades locales.
An Investigation of Local Site Effects Using Linear and Nonlinear analysis and Comparison Between Them
Authors: Komak Panah Ali , Nouri Aylin
Published: September 2019

Recent code provisions for building and other structures (1994 and 1997 NEHRP provisions, 1997 UBC) have adopted new site classification. The new site classification system is based on average shear wave velocity to a depth of 30 m. when the shear wave velocity is not available; other soil properties such as undrained shear strength can be used. The study of propagation damages in various earthquakes illustrates the importance of the site effect on the ground seismic characteristics. From the point of the earthquake engineering view, the most important characteristics of the strong ground motion are amplitude, frequency content and duration. All of these properties have a significant effect on earthquake damage. The behavior of soils under cyclic loading is basically nonlinear and hysteretic. Ground response analysis is used to predict the movements of the ground and develop a design response spectrum in order to determine the dynamic stresses and strains and earthquake forces. The profile was studied by using various methods of soil response analysis and finally, the results were examined. In this paper, soil responses were examined by NERA, EERA software and the results compared with each other. Eventually, we concluded that the values obtained from the EERA are more than the value obtained from the NEERA software.

Published: September 2019

Human beings always live in embedded place called home where is one of the main places influence them. Since home has mental relationship with family, its architecture is severely important and undeniable. It is established that training occur in every periods of life and childhood has the most significant role comparable to other periods. On the other hand, the concept of home is widely used in child welfare policies and practises, we do, however, recognize that children’s social relations and belonging to the place called ’home’ are fluid, contextual and mobile. Moreover, the quality of growing place of children is the basic for maturity and training, so the role of architecture becomes more worthy. In the current work with focus on the role of home architecture on the children’s training, different parameters were studied. In addition, the role of architecture in some characters of children such as creativity, mobility, identity and etc is the important effect of this art on the children’s training which attracted little attention since now. This study, using descriptive and analytical methods, enumerates some of the needs of the child, The capacities of architecture in the direction of training, in the other word, the role and effect of architecture of living place on parenting and the formation of their personalities and finally by providing appropriate solutions architecture, such as educational workshop spaces, spaces with high security, both physically and mentally and to improve parenting are discussed.

Authors: DU YILENG , ZUO HONGJUAN
Published: September 2019

It has been a long time since humans started using waste materials in engineering applications. This approach not only reduces the yield of waste, while minimizing the costs of disposal but also limit the cost of new materials. In the field of construction, the reuse of waste concretes has been a strong research in recent years. However the processing of the wastes normally involves complicated processing and lab equipment. In this report we crush and dehydrate waste concretes with normal lab facilities and re-make the cement composites. The waste concretes were crushed and dehydrated at two temperatures, 1280 and 1400 ˚C. To balance the concentration of silica and lime, extra lime at 28.5 % and 16 % were added to the waste concretes. The resultant materials were evaluated with respect to the chemical composition, mechanical properties, and microstructures. It is concluded that the material dehydrated at 1400 ˚C and containing 28.5 % lime presents the best mechanical performance. This report presents a simple and inexpensive method to reuse the waste concretes in applications such as pavements.

Published: September 2019

The paper aims to determine acetic and propanoic acid concentrations in some selected samples of kerosene used in Nigeria. The Armfield Liquid-Liquid Extraction Unit was employed to carry out the study. Distilled water and kerosene samples from five different sources were used for the investigation. The parameters taken into consideration during the course of the experiments were time, thermal conductivity, temperature, flow rates and concentration of the acid. It was deduced from the research that the temperature and the conductivity decreased with significant decrease in concentration of the acid and vice versa. The results gotten from the extraction of the kerosene samples also showed that sample A, sample D, and sample E did not contain acetic acid while sample B and sample C had traces of acetic acid, with sample C having traces of propanoic acid. After comparing the values with the standard classification of acetic acid, it was discovered that the concentration of both acetic and propanoic acid in the samples were not significantly sufficient to harm human beings.
EFECTO DE LA CONCENTRACION DE QUITOSANO EN LA DISMINUCION DE LOS SOLIDOS SUSPENDIDOS EN EL AGUA DE INGRESO A LA PLANTA DE TRATAMIENTO DE BELLAVISTA.
Authors: Rosero José Augusto , Suárez Heredia Martha Azucena
Published: September 2019

Una de las primeras etapas en la potabilización del agua superficial es la coagulación- floculación de sólidos suspendidos. La presencia de sólidos altera las propiedades físico-químicas del agua, pudiendo afectar su color y sabor, generando en algunos casos contaminación microbiológica. El coagulante-floculante más utilizado es el sulfato de aluminio, sin embargo, la presencia de alumio residual en el agua, se ha asociado con trastornos en la salud de los consumidores, ya que el aluminio como sal soluble llega a ser biodisponible en el metabolismo humano. Por tanto, se plantea la posibilidad de reemplazar el sulfato de aluminio con biopolímeros no tóxicos como el quitosano. Así, se analizó, mediante pruebas de jarras, el agua que llega de diferentes vertientes a los tanques de almacenamiento de la planta de tratamiento de Bellavista en la ciudad de Quito. Se encontró que el quitosano en concentraciones de 8 ppm ocasiona un 19,7% de disminución en la turbidez del agua cruda; a esta misma concentración el sulfato de aluminio genera el efecto contrario, produce un incremento de turbidez del 19,3%. Debido a este comportamiento, el quitosano puede convertirse en una alternativa viable para clarificar agua para consumo humano, además de su cualidad como polímero natural.

Los tratamientos fueron cuatro dosis de Mg (25, 50,100, 200 mg l-1 ) y dos dosis de Al (0 y 25 mg.l-1) a tres diferentes valores de pH de manera que la combinación de dosis de Mg-Al y pH produjo los siguientes tratamientos 1) 25-0 pH 4; 2) 25-25 pH 3; 3) 50-25 pH 3; 4) 100-25 pH 3; 5) 200-25 pH 3; 6) 25-25 pH 5. Se utilizaron plantas provenientes de cultivo de tejidos del clon “Gran Naine” que se pusieron a crecer por 63 días en solución nutritiva en potes de 20 l de capacidad. Las variables evaluadas fueron: altura de planta, circunferencia de pseudo tallo, producción de biomasa, ritmo de emisión foliar, área foliar y absorción de nutrimentos. El Al redujo el valor de todas las variables de crecimiento con excepción del ritmo de emisión foliar. La dosis de 50 mg l-1 de Mg disminuyó parcialmente el efecto de la toxicidad del Al en la altura de planta y circunferencia de pseudo tallo. Dosis más altas de Mg presentaron resultados similares a 25 mg l-1. El Al afectó la biomasa total, principalmente la de las raíces de primer orden, pero al subir el Mg disminuyó parcialmente este efecto. El Al disminuyó la absorción de agua, pero la dosis de 50 mg l-1 de Mg disminuyó levemente el efecto del Al en esta variable. La toxicidad de Al se redujo al aumentar el pH de 3 a 5. El Al redujo la producción de biomasa en 65%, mientras la absorción total de nutrimentos disminuyó entre 56 y 89%. El orden de reducción del contenido de los macronutrimentos en los tejidos fue Mg≥Ca>S>N≥K>P y el de los micronutrimentos fue Fe>Mn>Zn>Cu=B.
