Children with intellectual disabilities (ID) can develop new skills and acquire more knowledge, but they need tools that allow them to do it at their own pace, which is often not the same as that of many children of similar ages. Game-based learning is a useful way to contribute to this learning. Although there are many games for computers and mobiles, they are not necessarily appropriate in the case of DI. Therefore, this article presents JIT, a web application developed trying to help people with ID in learning basic topics (such as colors, geometric shapes, numbers, spatiality, etc.). The application was designed and evaluated with the collaboration of teachers and technicians dedicated to working with people with ID, aiming for users to feel motivated to learn, and to be able to practice and remember the studied topics in a playful way. Thus, JIT can be used by special education and related teachers as an educational tool, also having the possibility of adding more topics and customizing the different activities available.

Virtual reality in the educational environment, due to its great potential, is capable of immersing students in immersive and multisensory environments through surround sounds and images that captivate their attention. The present research is carried out based on its objective, which is to describe the benefits generated by the application of virtual reality in the teaching of reading and writing in students of General Basic Education. A documentary research with a qualitative approach and deductive method was developed. With respect to the results achieved, a significant level of ignorance and application of technological tools by the teacher was patented, so it is notorious the setback in the teaching of this, since, according to data thrown by the INEVAL from 2012 to 2019 were 12% and 18.10%, so that the use of such technological tool was taken into consideration for the consolidation of significant learning and thus reduce the poverty gap of the educational field currently, to which a large part of students agree with the use of is. Finally, virtual reality creates learning environments that generate relevant experiences, favoring reading and writing.

The organizations' information hosted in databases is a very important asset and must be protected from cyber-attacks. In the investigation, threats than endanger the SQL Server 2016 Standard database engine were identified, and how it could exploit the present vulnerabilities. It is proposed to conduct a study of a Security Information and Event Manager (SIEM) to identify if it is a valid tool to reduce the attacks that critical data may suffer. Also, it was analyzed how a SIEM would contribute to comply with the controls of the Information Security Government Scheme version 2.0 (EGSI v2.0). It was demonstrated that a SIEM detected security incidents in the database in a timely manner such as: SQL injection attacks, force attacks, among others. It was also verified that it helps to comply with those EGSI V2.0 controls related to access control, operations security, and security incident management.

At present there are many forms and methods of software development, which can meet the needs for which they were created or will be created, leaving aside fundamental and fundamental situations to always take into account, such as security processes and information auditing. Now, when there are public and/or private companies, dedicated to develop software in a collaborative way, quality must always be taken into account, measured by efficiency and efficacy, both in the software product and in its construction process. This scientific paper aims to generate an approach to improve software quality through the implementation of continuous integration and delivery practices. The benefits of integration and continuous delivery in the software development process are described, and recommendations are provided on how to implement these practices effectively. In turn, several case studies are presented that illustrate how continuous integration and continuous delivery have improved software quality in different development contexts. As a final part, it is concluded that these are essential practices to improve software quality, reduce development costs and increase customer satisfaction. It is recommended that organizations adopt these practices and integrate them into their software development process.

El presente estudio consistió en la determinación del volumen de explotación en el embalse LaEsperanza mediante el método batimétrico de posicionamiento 3D, utilizando ecosonda GarminechoMAP™ en conjunto con la aplicación de sistemas de información geográfica (SIG). Se acopló unmodelo digital de elevación “DEM” de resolución 12,5 m x 12,5 m, descargado del satélite ALOSPALSAR para obtener el área y relieve topográfico digital de la cuenca. Además, se estimaron dosecuaciones polinómicas en función del nivel, volumen y área del embalse, mediante un análisisde regresión por el que se obtuvo un volumen máximo de explotación de 428,64 Hm3 (cota 66m.s.n.m.), con una extensión del espejo de agua de 2.348,55 ha. En conclusión, la determinacióndel volumen con dispositivos tecnológicos y software de construcción cartográfica es una parteclave del diagnóstico en la gestión del agua e imprescindible en el análisis para la correcta gestióndel volumen embalsado en la represa La Esperanza.

El objetivo de esta investigación fue determinar la característica superficial actual que hainfluido mayormente en el azolvamiento del embalse La Esperanza, en la provincia de Manabí,costa de Ecuador. Para lo cual se delimitó y caracterizó fisiográficamente la cuenca en estudio,mediante la utilización de los Sistemas de Información Geográfica (SIG), a través de un modelode elevación digital (DEM) descargado del satélite ALOS PALSAR (https://www.asf.alaska.edu/),complementándola con el Sistema Nacional de Información (www.sni.gob.ec). Se determinóuna mayor geomorfología de vertientes regulares (32,13%) y mesas muy disectadas (32,42%) conuna geología de tipo sedimentaria entre areniscas tobáceas, lutitas y limolitas propensas a laerosión hídrica. En conclusión, las microcuencas de Membrillo y Bejuco en su parte alta presentangargantas de valles encañonados con pendientes que alcanzan los 30 grados, que unida a laprecipitación se convierte en la principal característica superficial que actualmente ha influidocon mayor azolvamiento en dos de los ramales del embalse.

La finalidad de esta investigación fue estimar la huella de carbono generada por la producciónde huevos en la granja avícola Velasco, en la provincia de Manabí, costa de Ecuador. Mediantela aplicación del método cuantitativo no experimental se realizó un diagnóstico de la granjabajo estudio, posteriormente se cuantificaron las emisiones de gases de efecto invernadero quese generan a partir de las actividades productivas desarrolladas en la Granja Avícola Velasco,multiplicando el consumo de cada actividad por su factor de emisión. Se obtuvo que en la granjase emiten 110.91 ton de CO2e al año, siendo la etapa de postura la de mayor porcentaje (74,57%),mientras que la producción de alimento fue la categoría de mayor aporte con un 84.50%.

Este estudio tiene como objeto proporcionar una actualización del conocimiento de poliquetosbentónicos registrados en Ecuador Continental. Se realizó una revisión de la información disponiblesobre especies registradas desde 1865 hasta el 2020, de lo cual, se obtuvo el número de génerosy especies por familias proporcionando un listado de poliquetos bentónicos para el país. Se hanreportado 143 especies en total, en donde, 20 han sido registradas anteriormente con su sinonimia.Existe un importante aumento en la biodiversidad de poliquetos para el país y su taxonomía hatenido muchas controversias, lo que se ve reflejado en ciertas familias. Se menciona que, El Golfode Guayaquil es el área donde se ha encontrado un mayor número de registros de poliquetos.Con las nuevas tecnologías y disponibilidad de información, se podría incrementar este dato; esnecesario considerar la distribución biogeográfica de las especies para una mejor identificación,además de, con ayuda de análisis de ADN y la opinión de especialistas, esto permitiría realizar unaactualización viable sobre el conocimiento taxonómico de las especies de poliquetos para Ecuador

This article provides a documentary review of educational systems, based on their structure, organization, regulations, characteristics and problems; in addition to establishing the different training levels in which they are articulated, in accordance with the International Standard Classification of Education (ISCED). Special emphasis is made in the educational systems of countries such as: Spain, Argentina. Bolivia, Colombia and Venezuela, establishing comparisons between them; which allow us to identify common aspects and establish the differences between their models, given the multiple factors that affect the educational path of each country. In the same way, an informative tour is carried out on the trends of the educational systems and the analysis of ten scientific articles that address the topic, which allow us to better understand their peculiarities, determining that there is currently a great variety of trends in educational systems that seek to achieve successful models to improve educational quality and economic development in their contexts. Finally, the challenges of educational systems are addressed, the trace indicates that they are diverse, but they have common challenges associated with the fourth revolution, in context with education 4.0 and Steam; which in turn are consistent with sustainable development, within the framework of the digital transformation that affects all fields of society. The educational systems try to respond to the challenges that the current and future situation demands, preparing students in additional abilities and skills to those traditionally received, so that they adapt to change, with talent and competencies relevant to the new scenario.

The development of computational thinking is one of the challenges of the current educational system, since in the knowledge society in which we find ourselves, the ability to solve and decompose problems, pattern recognition, abstraction and algorithmic thinking are factors that facilitate the development of skills and  skills required by the citizens of the future in the digital age we are facing. Taking into account the above, the purpose of this article is to carry out a documentary review on the state of the art of teaching computational thinking in preschool and primary school, therefore, it is presented as a theoretical review, where the method is used. corresponding to a descriptive and interpretive study through a hermeneutic documentary analysis of the consulted literature. To achieve the purpose, initially the concept of "computational thinking" is approached, linked to other concepts such as 21st century literacy, preschool and primary education, educational trends and teacher training. Subsequently, a database generated from the review of the publications of the last five years in academic search engines that emerged from the empirical research is analyzed. Finally, a discussion is made about the results found and the research needs in this regard. One of the greatest conclusions that can be given is the marked tendency to associate the development of computational thinking with programming and technologies such as educational software, video games and robots. Efforts to develop "unplugged" or "unplugged" strategies for areas other than mathematics and technology are still in their infancy.
