Digital territories focus on community transformation through sustainable development, saving resources in local governments, bridging the digital gap, and using technology to build smart infrastructure. This article presents the design and implementation of a smart system, called the Waste Treatment System (WTS), for controlling parameters of waste decomposition in the trash bins installed in Riobamba city (Ecuador). The prototype allows monitoring in real time both the amount of waste and the level of rottenness of garbage by means of the measurement of different parameters that indicate the characteristics of the leachates generated inside. The motivation of this work was to yield an efficient solution to urban waste treatment that optimizes resources in the collection process by providing real-time information to improve collection frequency vehicles and also reduce emissions by the decomposition of organic waste. The tests allowed assessing technical aspects such as the maximum coverage of wireless communication, the transmission channel capacity for each prototype, the data-processing requirements, and other more particular parameters such as the production of leachates due to the frequency of collection and the environmental conditions, which will be useful in future work on environmental impact.

The way in which the human being learns certain complex contents has always been a focus of interest and a challenge for researchers. Given the fact that children's cognitive abilities do not fully develop until a certain age, this topic is particularly important in the young children's learning scope as they do not correctly and easily learn some content of abstract nature, such as contents in math class. This work presents the results of the use of an application called "Mathematics Learning System with Augmented Reality based on Kinect" (SAM-RAK by its acronym in Spanish), which was designed to cover basic topics of mathematics in the Basic General Education level (EGB by its acronym in Span-ish) in Ecuador. The research was carried out under an experimental quantitative approach with 30 children (18 girls and 12 boys), who study in third grade of EGB level, from 2 different educational in-stitutions in Riobamba city. In order to obtain the results that evaluate the developed application, a pre-test and a post-test were applied, which were contrasted with the student’s t-test for paired samples. The statistical evidence suggests that the proposed computer system had a positive effect on children's performance, when it was used as a support tool in the classroom. The system was more effective in low performance children compared to those of high performance. It was also proved that children were motivated and showed positive attitudes when using the proposed System.

Este trabajo detalla el uso eficiente y reutilización de recursos de infraestructura a través de la migración de una red de acceso convencional a una nueva red que implemente tecnología VDSL/FTTX para mejorar los servicios de telecomunicaciones en la ciudad Guano por intermedio de CNT EP. Se realizó un análisis comprensivo del estado actual de redes FTTX que utilizan tecnología VDSL para establecer el aporte en la mejora de servicios en redes implementadas. Por otro lado, se realizaron mediciones de los principales parámetros eléctricos (resistencia de bucle, atenuación y señal ruido) en 427 redes telefónicas en diferentes sectores del cantón Guano para conocer sus estados actuales y determinar los sectores con mayor deficiencia de servicio y que por ende no cumplían con los valores mínimos admitidos en la normativa de CNT EP. La implementación se realizó en el sector El Cisne conforme a la Normativa de diseño de Planta Externa con Plataformas de Acceso Exterior de CNT EP. Los resultados de la implementación permitieron tener un 91.27% de nivel de aceptación de la red con respecto a la resistencia de bucle, un 91.03% de aceptación con respecto a la atenuación y 95.29% respecto a al SNR, conforme a los establecido en la normativa vigente. Por lo tanto, la red de acceso implementada permite brindar QoS en el servicio de voz y datos para garantizar una reducción de gastos operativos, aumentar la competitividad, prestación de servicio eficiente a los clientes y cumplimiento de requisitos de la normativa de CNT EP. This paper details the efficient use and reuse of infrastructure through the migration from a traditional access network to a new network that implements VDSL / FTTX technology in order to improve telecommunications services in Guano city through CNT EP. The current state of FTTX networks that use VDSL technology was analyzed in order to establish the contribution for improving services in networks already implemented. On the other hand, measurements of electrical parameters (loop resistance, attenuation and signal noise) were carried out on 427 telephone networks in different sectors of Guano city to know their current states and decide the sectors with the greatest service deficiency and did not meet the minimum values allowed in the CNT EP regulations. The implementation was carried out in El Cisne sector in accordance with the External Plant Design Regulations with External Access Platforms for Network Deployment with VTL / FTTC Technology, by CNT EP. The results of the implementation showed 91.27% acceptance level of the loop resistance in the network, a 91.03% acceptance level of the attenuation and a 95.29% with respect to the signal noise, in accordance with the parameters established in the regulations. In conclusion, the access network with VDSL / FTTC technology implemented allows to provide QoS in the voice and data service in order to guarantee an efficient service to the clients and fulfilling all the requirements requested by the CNT EP.
