In this study, it was found that the participating students preferred to use their smartphones before any other electronic device to have carried out the chosen activities. This information showed that immediate access to schoolwork anytime anywhere has been essential for the modern student. The accessibility seen in smartphones has been a key factor influencing students' willingness to complete their studies. This information has been able to help teachers understand the potential of using smartphones as a useful tool in learning, rather than simply having a distraction or entertainment. Thus, with adequate supervision, guidance and structuring of the activities carried out by the student, Smartphones are no longer the enemies of anxiety, and have been able to become an ally in learning, whether in multimedia applications or developed for this purpose. This made it easier for the teacher to stop being the provider, coordinator and supervisor of the classroom and pass that responsibility on to the students, allowing them to use their own devices. Instead of trying to prevent students from using smartphones, it was better to be aware of this by adopting activities such as information search, collaboration with teachers and peers, practical activities used in this study, and formative assessment. In addition, an approach using software could be observed in each department of student life, whether initial, intermediate or higher level, with educational environments using middleware adaptable to each subject.

This article presents a methodology based on the agile XP process for the development of robot-oriented software in educational platforms using the ROS middleware. The final result was a set of evidences such as user stories, UML-based diagrams and lines of code in the Python language that demonstrate good code quality practices in software development with the use of the object-oriented paradigm. A modified agile methodology is obtained with an evolutionary and incremental design but with a rigorous documentation useful for educational and research projects. [ABSTRACT FROM AUTHOR]

The services and systems are in the midst of a major transformation. Users are becoming more diverse in their needs and requirements, resulting in an increased demand for sophisticated, individualized communications services that improve their experience. In this context, information management is an important aspect, so charging information is a key element when we want to provide services in a converged environment. Currently, charging data are distributed between different network elements involved in service provisioning. Therefore, it is a challenge to implement a mechanism to keep data consistency that allows for a real services convergence. This article proposes a mechanism to ensure data synchronization and consistency in IMS environments. To achieve this goal, we adopted databases synchronization techniques already tested in the information technology field. [ABSTRACT FROM AUTHOR]

Ecuador, as some Latin American countries, implements the system ISDB-T for Digital Terrestrial Television (DTT) that enables the issuance of interactivity through the Ginga middleware. The DTT can involve a change in the quality of the content, but above all an opportunity to access to the knowledge society. This research describes a dynamic workplace, the integration of multidisciplinary teams in the production of two sports programs "Aventura-T"; employing qualitative methodology, the instruments used are observation, semi-structured interviews and focus groups. It is concluded that the applications in Ginga NCL generated comply with quality standards for emissions of DTT. [ABSTRACT FROM AUTHOR]

In order to achieve significant progress in computer science, new and powerful solutions in the field of information technology are required; some of the current processes would not be possible without access to powerful computing resources. This investigation focused on treating a system for harnessing these resources in a distributed environment called a grid. The grid is based on the sharing of distributed computing resources for multiple purposes in a computational process. Currently, researchers are required to understand some advanced concepts in order to incorporate all the advantages of grid architecture. The idea throughout this project was to create a portal oriented to researchers who wish to execute tasks using distributed resources, without their having to delve into the technical details of grid technologies. The first part of this article describes the basics for grid portals and the proposed model; the article subsequently emphasizes the components of the prototype including all relevant elements for modeling the portal, such as middleware, frameworks, web server, and portlets. Following is a brief description of the results achieved throughout the project, including the satisfactory performance of the portal, with the conclusion that the execution of tasks using distributed resources through the portal takes considerably less time than with other methods, in addition to being more user-friendly. Finally some significant recommendations for future work are identified. [ABSTRACT FROM AUTHOR]
