Non-alcoholic fatty liver disease affects approximately thirty percent of the global population, yet public awareness remains dangerously low among young adults facing occupational risk factors. This study introduces the Fatty Liver Awareness Game (FLAG), an educational serious game designed to improve liver health literacy among software engineering students at the University of Guayaquil. While evaluated with this specific sample, FLAG is intended for the broader target population of young adults in developing nations who face occupational sedentary risk and limited access to preventive health education. Through a controlled experiment with fifty participants randomly assigned to game-based or traditional lecture instruction, the game demonstrated superior effectiveness, with a twenty-percentage-point advantage in post-test scores and a seventy-two percent reduction in incorrect responses compared to fifty percent in the lecture group. The large effect size (Cohen’s d = 1.43) and reduced performance variability among game participants indicate that interactive, feedback-rich learning environments can outperform passive instruction for this population and content domain. While the present design does not isolate the contribution of individual game elements—such as narrative framing, explanatory feedback, or mini-game interleaving—the results establish FLAG as a replicable model for digital health interventions targeting underserved populations at critical developmental junctures. Future component analyses are needed to determine which specific design features drive the observed advantages. © 2026 by the authors.

Nowadays, there is a rapid technological progress around the world that has enabled realities long ago unimaginable. We live in a technological era that represents new possibilities and challenges for society, and for the educational models in each country [1]. Research on smart education, which has forced the educational community to rethink on new ways of learning and teaching has been developed globally. Due to the advent of artificial intelligence (AI), the educational model for both, teachers and students will change. Nevertheless, to transform educational systems, it is necessary to update and train students, educators, and administrators effectively [2]. This research aims to describe the possible applications of AI in education from: 1) the automation of administrative tasks; 2) collection and analysis of information [3] to create smart content; 3) the implementation of virtual assistants in the teaching-learning process; 4) the potential delivery of lectures by humanoid robots with AI. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Web accessibility is increasingly recognized as a key factor in assessing higher education institutions’ quality, inclusion, and social responsibility. This topic is particularly relevant in Latin America, where significant disparities in digital equity and access to resources persist. This study analyzes the web accessibility of the top 20 Latin American universities based on their rankings in QS World University Rankings, Webometrics, SCImago Institutions Rankings, and Times Higher Education (THE). Using automated and manual assessment tools, including WAVE, PageSpeed Insights, and expert assessments, the study identifies 434 contrast errors, 210 missing text alternatives, and 262 navigation issues on university websites. The results show that universities such as USP, UNAM, and Unicamp rank high in international rankings but have critical accessibility deficiencies, highlighting the gap between digital visibility and inclusion. By aligning with WCAG 2.2 and the Sustainable Development Goals (SDGs), in particular SDG 4 (Quality Education), SDG 9 (Industry and Innovation), and SDG 10 (Reduced Inequalities), universities can improve global competitiveness while fostering digital inclusion. This research proposes a structured framework to promote accessibility through a seven-phase methodology, addressing barriers, implementing improvements, and validating effectiveness. The findings provide a systematic approach for universities to optimize accessibility, improve user experience, and strengthen their international positioning

Health information on the Web can make patients better informed about a disease, which according to several studies leads to better treatment results. However, the health information found on the Web is not accessible because it presents barriers that prevent people from easily accessing it because it does not comply with the standards of the Web Content Accessibility Guidelines (WCAG) 2.1. Therefore, in this study, we present an analysis of the accessibility of the seven most visited health websites in the world. To analyze the accessibility of medical websites, we apply an automatic review method. The results show that health websites have frequent problems related to the lack of alternative text, empty links, and contrast errors. This research can contribute to future work related to accessibility in health and medical sites. Finally, we suggest designing a combined method to review each website’s accessibility barriers to complement the automatic review. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Technology has the potential to redefine museums, opening the opportunity of new ways to connect with visitors. In the pandemic, museums had to close their doors and in-person visits were canceled. In reaction to this reality, many museums rushed to generate digital tours of their works and collections. The creation and development of these visits were born from the need to continue with virtual visits to continue to bring the knowledge that these institutions house closer. Today a possible approach is to create hybrid experiences that utilize digital technology capable of enriching a physical visit to museums. In this context, this paper addresses three experiences developed in Ecuador: (1) The Spiral of Memory proposal developed at the National Museum of Ecuador (MUNA), (2) The Animals of Yesterday and Today proposal developed at the Smithsonian Virtual Museum and (3) Interactive Museums as Pedagogical Mediators, digital educational resources in virtual learning environments. The conclusion of these experiences led to the conclusion that museums are spaces of interaction that contain an infinity of resources that allow children to create their own stories and compositions from the observation of real facts and situations, presented through the creation of physical or virtual experiences in these cultural spaces. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This study addresses the optimization of quality management in health insurance to achieve sustainable cost reduction while maintaining service standards. Utilizing a mixed-methods approach, the research combines literature review and survey data to analyze user perceptions of service quality and the role of digital technologies. The survey included a diverse sample of health insurance users, capturing insights on satisfaction, technological tools, and quality management processes. Key findings reveal that user satisfaction is significantly influenced by transparency, accessibility, and the integration of digital tools such as mobile apps, web portals, CRM systems, and telemedicine. Correlation analyses showed a moderate positive relationship between the frequency of technology usage and perceived effectiveness, satisfaction, and future impact expectations. Despite moderate satisfaction levels with current technologies, participants emphasized the need for advanced tools to enhance efficiency and user experience. Demographic analysis indicated that educational level positively correlated with satisfaction, highlighting the importance of user training for technology adoption. Additionally, older users reported lower satisfaction, signaling the need for more inclusive and user-friendly systems. Gender differences in satisfaction and the positive association between customer loyalty and perceived service quality further underscore the importance of personalized strategies. The study concludes that digital transformation in health insurance can sustainably reduce costs while meeting user expectations. Key recommendations include increasing user education, investing in advanced technologies, and tailoring solutions to diverse demographic needs. These findings provide actionable insights for insurance companies aiming to improve operational efficiency and enhance service quality sustainably.

This article reports a study in which three experimental tasks (SIMON, Go / No-Go and Stroop Victoria) were adapted and validated to evaluate the inhibitory control and interference control in a sample of Ecuadorian students. The sample consisted of 100 students between 6 and 15 years old (M = 10.13 years, SD = 2.48) belonging to the public education system of Ecuador. The process followed in the adaptation and validation was through the linguistic translation of the experiments, followed by an expert judgment and a pilot study. In the results it was found that there are no statistically significant differences in the measures that assess the inhibitory control and the interference considering the sociodemographic variables of the participants as comparison factors. In the correlation analysis we found a statistically significant association between the measurements of the experiments. We conclude by analyzing the associations found and underlining the need to continue providing evidence in the research line of adaptation and validation of test for using in neuropsychological evaluation.

Comprehensive Plan for the Induction of Environmental Awareness Based on Household Waste
(2026)
Jadán Guerrero, Janio
This article presents the results of an investigation applied to 30 residents of a neighborhood in the municipality of Piedecuesta, Santander. The purpose of this research is to develop a comprehensive plan to promote environmental awareness based on household waste (DR), through the application of a survey that allows to know the previous knowledge of the community about the environmental management generated daily in their homes. The strategy employed focuses on environmental education talks, interactive presentations and the delivery of a brochure that comprehensively addresses environmental awareness in relation to household waste. A mixed methodology was used in the research, through the following phases: exploration, planning, observation and reflection. Finally, the following findings were obtained: it is observed that the community lacks information on the separation of DR: organic, recyclable and non-recyclable. In conclusion, the lack of environmental education in the municipality has resulted in a large amount of household waste that is neither separated nor properly used, which generates several negative consequences such as: environmental pollution, greater accumulation in landfills, greenhouse gases (GHG), among others. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026.
