In recent years, it has been shown that emotions influence what we learn and retain, and second-language learning is no exception to this phenomenon. Currently, a variety of mobile learning applications offer content for language learners, and a wide range of languages are presented. The analysis of emotional data in learning environments has been...

Internet of Things (IoT) technologies allow building a digital representation of people, objects, or physical phenomena to be available on the Internet. Thus, stakeholders can access this information from remote places or computational systems could analyze this data to find patterns, make decisions, or execute actions. For instance, a doctor could...
This article describes a proposal about a trust system for e-commerce platform based on semantic web technologies and trust dimensions rules. We try to expose a system that allow to manage communication processes between e-commerce platforms and users in a trustworthy manner. It allows the data flows and transactions gain more trust across the enti...
This article suggests the implementation of Learning Analytics model using an immersive scenario that seeks the user's attention with gamification elements to support the practice of English language in Latin American countries, finding fuzzy logic as a solution in the analysis and evaluation part in the model.KeywordsLearning analyticsFuzzy logicE...
This article introduces an immersive scenario based on gamification, seeking to contribute to the preservation of cultural heritage in Colombia by displaying different places, contexts, and their corresponding description; it also allows participants to strengthen a second language mastery through the reading and listening practice. Finally, the po...
Nowadays, information and communication technologies (ICTs) and virtual training have increased the use of educational resources. This growth use has highlighted educational resource reuse and availability problems. Resource descriptions adapted to particular needs and the lack of metadata enrichment taking advantage of the benefits provided by the...
This article shows the application and design of a hybrid algorithm capable of classifying people into risk groups using data such as prehensile strength, body mass index and percentage of fat. The implementation was done on Python and proposes a tool to help make medical decisions regarding the cardiovascular health of patients. The data were take...

... An additional key challenge is a well-known reluctance of most authors of resources to even provide metadata at all. Several studies have suggested metadata sets that describe OER more systematically and, thus, enrich and facilitate the metadata report to improve OER availability and OER description (Herrera-Cubides et al., 2022). ...

... This table shows the research interest in obtaining an appropriate image examination system to detect the retinal disease with a FRI/OCT database. In the literature, several recent approaches confirm the need of feature-assisted automated diagnosis systems to reduce the detection complexity [27][28][29][30][31]. ...

... The car's clockwise turn might easily result in additional collisions [27,43]. It has been observed that more than 75% of compact vehicles experience lateral spins after collision with steel guardrails [1]. When the angular acceleration reaches a specific threshold [39], the vehicle turns rapidly [14], potentially dispersing the drivers and passengers [9,44]. ...
