Introduction: Rehabilitation nursing care has its practice outlined in the international scenario, constituting an evidence-based care that aims to add quality of life and, for that, it is necessary that nursing theories scientifically support the practice performed. It is known that many health and nursing theories make up the practical scope of assistance in this specialty, however it is time to reflect theoretically what we can do differently. Objectives: To build a theoretical model about rehabilitation nursing as an emancipatory process, as well as to internally validate the content and apply it as a theory in the reality of rehabilitation. Method: Methodological study of theory construction in nursing. Results: It is expected to build a Rehabilitation Nursing Theory in the light of Axel Honneth's Theory of Recognition, through an orthodontic methodological flow and literary foundation and practical experience. Conclusion: Further studies are needed to deepen rehabilitation nursing care as a science. That said, the present study proposes the construction of a Rehabilitation Nursing Theory.

Background: Postural education is essential to promote proper body posture and prevent the adoption of incorrect postures, which can result in pain and musculoskeletal damage (1, 2, 3, 4, 5). The implementation of school-level programs has a strong influence on children's health and quality of life (6, 7). Objective: To analyze the existing evidence concerning postural education programs implemented at school level. Methodology: Through an integrative literature review, the PEO methodology (participants, exposure and results) was used. The data collection was conducted in April 2020 in the CINAHL and PubMed databases. Results: The analysis of the articles included allowed us to identify that postural education programs have benefits in terms of knowledge, static and dynamic postural parameters, backpack weight reduction, musculoskeletal pain level and shoulder misalignment. Conclusion: The evidence shows that the implementation of postural education programs, at school level, has positive results in promoting children's health.

The advance of the earth observation satellites has been very useful for carrying out several important studies related to areas that relate global change, as they provide cartographic information of the planet and real-time data that helps visualization and monitoring of natural disasters. The Emergency Management Service (EMS) of the Copernicus Satellite is a clear example of Earth Observation Satellites offering timely and accurate geospatial services and information derived from the detection of satellite disasters and completed by available data sources, a clear example This is the Copernicus Sentinel-2 mission, which comprises of two polar orbit satellites placed in the sun's orbit with a 180 ° phase between them, this project aims to maintain a constant monitoring of surface changes Earth, as well as approaches such as emergency management, security and climate change. With the objective of knowing its operation, a simulation of an observation satellite was designed to provide coverage to Latin American countries trying to get closer to reality in case some kind of these satellites are implemented in a specific place in the southern zone of the American continent.

An analysis of the electromagnetic fields measured on the campus of the Escuela Superior Politécnica de Chimborazo (ESPOCH) is presented, ESPOCH has a considerable population transit with about 14,000 students, administrative staff, and teachers who remain exposed daily, during their working hours, to non-ionizing radiation generated by a base station installed by a mobile phone service operator. It leads a question, whether the health of those exposed to these radiations could be compromised due to this. The present research study shows the measurements in the 1900MHz GSM band for seven days at fixed location:  370m away from the antenna. The main objective is determining if the radiation levels are within established limits by the regulatory entity. Or identify if there is a risk for the university community for the increasing number of antennas for the mobile telephony and mobile broadband service. In the discussion we show that electromagnetic fields are within limits established by the World Health Organization.

The study of the proportion has been relevant in the design from the Greek period to the Renaissance. There are countless treaties that address the issue but not explicitly. From the absence of a specific theoretical body of the proportion in the periods of study, it is established as objective to determine the constituent elements of the proportion from the historical-critical analysis, through the analysis of the definitions from the Greek period to the Renaissance, the design procedure and the determination or not of the components of a proportional system. Methodologically, the historical-critical methods were used to unravel the elements that characterize the proportions or systems, the proportional analog method to establish the common elements in the definitions that emerge during the study periods, the systemic-structural method for determining the application guidelines and the components of a proportional system. The critical historical analysis of the proportion from the Greek period to the Renaissance allowed us to establish the constituent elements of the proportion that, due to its complexity, transcends the level of compositional category and becomes a proportional system, as well as demonstrating the relevance of the management of the proportion in the design and its link with thought and aesthetic considerations.

In the present work, the delay suffered by the GPS signal during the transmission through the propagation channel is analyzed, which is affected by factors, characteristics and conditions of the atmospheric layers. The troposphere due to the wet and dry components produces the hydrostatic delay which represents approximately 90% of the total delay of the signal that depends directly on the atmospheric pressure and the tropospheric delay which is influenced by the water vapor and the temperature. To estimate the delay, we chose the sample of the data of the days with the highest and lowest humidity and accumulated precipitation based on the Saastamoinen model, comparing the results with the analyzed data extracted from the EREC station of the GNSS Continuous Monitoring Network. Ecuador (REGME) through the processing of data with the RTKlib tool to assess the impact on the accuracy of the final solution in the positioning of the receiver.

Currently, field effect transistors made of silicon carbon are an emerging technology that is entering the market for power devices, due to the higher benefits of this family of semiconductors in relation to silicon. Due to its wide bandgap, presents several peculiarities of defectiveness within its structure that directly affects the electrical characteristics of the devices, the objective of this article is to determine the level of defectiveness inside the MOS structure, using the hysteresis characterization technique In order to achieve this objective, two families of MOSFET devices manufactured  in silicon carbide of different electrical characteristics were evaluated experimentally, the evaluated devices belong the same manufacturer. The level of defectiveness showed by each tested device, marks a trend according to their capability of electrical characteristics and family.

The problem of study English as a foreign language or bilingual education has been handled in a superficial way.  The experience gained during the teaching time has shown that the public schools´ students have low oral production and deficient pronunciation; meaning this that the correct development of this language is not achieved, in despite of the great help that ICT offers. The foregoing has led to conclude that the importance of the didactic factors in the phonetic elements of the oral expression is the general objective of this research. The methodological design research was conducted under the scientific investigation line, through the critical-social research, having as methodology type the descriptive-exploratory one, with the survey and direct observation as research techniques, considering as instruments, the questionnaire and the interview, based on closed questions investigated on the field; under a quantitative approach. According to the need, the scope is of qualitative type, because studies specific groups, converting it in a case of study. The proposal of this research is focuses on a Didactic Guide design with phonetic introductory methodology supported on the ICT, which improves the pronunciation, increases the students’ vocabulary and as a default will develop the oral expression.  The implementation of this proposal will identify the quality didactic factors that influence the teaching-learning process.  As a result, the right articulation of this research will develop in great benefit, achieving the academic excellence, based on standards and in line with the current globalized world, which means the mastering of the English language.

La represa de San Vicente, está situada en la cuenca alta del río Javita al noroeste de la Provincia de Santa Elena. Es una represa de tierras de 25 m de altura que embalsa unos 40 Hm3que se distribuirá a través de canales para conducir el líquido vital por gravedad,  favoreciendo a las comunidades ubicadas en varios sectores como: Colonche, San Marcos, Bellavista, Manantial de Guangala, Manantial de Colonche, Jambelí, Palmar, Bambil Desecho, Rio Seco, Aguadita y Cerezal, se establece que serían 26.000 las hectáreas que se beneficiarían en la provincia de Santa Elena (CEDEGÉ, 1984). La Subsecretaría de Acuacultura, junto a los  representantes del Ministerio del Litoral,  Ambiente y los habitantes de las diferentes comunas de la Provincia de Santa Elena, presenciaron la siembra de  120.000 de los 500.000 alevines de tilapia donados por la compañía MODERCORP que fueron sembrados en la represa de San Vicente de Colonche. (SA, 2008). Las tilapias desde que fueron sembradas crecieron y se reproducen sin control alguno, generando una densidad poblacional alta, reduciendo el espacio de traslado de estos organismos en el cuerpo de agua.Como consecuencia de aquello las tallas han disminuido, afectando  la disponibilidad del recurso en tallas mayores que satisfagan a los consumidores locales. Las pocas oportunidades de trabajo en las comunidades rurales,  hace que se dediquen a otras actividades que la zona les brinda, teniendo como un complemento en el sustento diario la pesca en la Represa sin predecir o prevenir los riesgos que estos representan, es así que desde las primeras capturas de tilapias no han cesado ni han planificado su sustentabilidad.

Las formas de coordinar las actividades de administración durante el último año, los reglamentos y normas han permitido que se genere cambios dentro de las instituciones de educación superior, es así como tienen origen las unidades de titulación en las diversas universidades del país, las mismas que para gestión y seguimiento de los trabajos de titulación de los estudiantes, se ha visto limitados en lo que respecta a recursos tecnológicos, aplicando simplemente procesadores de texto u hojas de cálculo, como apoyo en el desarrollo de las actividades de control, siendo así necesario involucrar activamente a las TIC, como medio de innovación en este tipo de procesos de aprendizaje. La presente investigación pretende socializar plataformas colaborativas propias de la Web 2.0, mediante un análisis comparativo, alineado a los conceptos de buenas prácticas en la gestión de proyectos y normativas de calidad para obtener los resultados propositivos en el desarrollo de los trabajos de investigación de los estudiantes. Se da a conocer, herramientas tanto propietarias como de código libre, con acceso en la nube, o con la posibilidad de ser alojadas y administradas dentro del parque tecnológico de la institución.
