Background: Thailand is rapidly transitioning into an aging society, creating an intergenerational caregiving gap that strains existing support systems. Objective: This study evaluated the effectiveness of “Young Care,” a community-based intervention designed to enhance youth knowledge, attitudes, and caregiving practices (KAP) toward older adults. Methods: A two-day structured training was conducted in Maha Sarakham Province in 2023 using a pre-post mixed-methods design. Middle and high school students participated in lectures, multimedia sessions, and experiential learning activities related to caregiving. Quantitative data were collected using validated KAP questionnaires, while qualitative insights were obtained from focus group discussions involving students, older persons, caregivers, and local leaders. Results: Post-intervention analysis revealed significant improvements in knowledge and attitudes (p < 0.001), accompanied by increased empathy, caregiving initiative, and a sense of moral responsibility among participants. Conclusions: The initiative fostered formal partnerships among schools, local governments, healthcare providers, and universities through memoranda of understanding. These collaborations enabled budgetary support and outreach to out-of-school youth, positioning “Young Care” as a scalable, youth-centered strategy to address Thailand’s long-term care challenges.

The integration of artificial intelligence (AI) into education requires frameworks that are not only technically robust but also ethically and pedagogically grounded. This paper proposes the Generalist Education Artificial Intelligence (GEAI) framework—a conceptual blueprint designed to enable privacy-preserving, personalized, and multimodal AI-supported learning in educational contexts. GEAI features a Trusted Domain architecture that supports secure, voluntary multimodal data collection via multimedia registration devices (MM Devices), edge-based AI inference, and institutional data sovereignty. Drawing on principles from constructivist pedagogy and regulatory standards such as GDPR and FERPA, GEAI supports adaptive feedback, engagement monitoring, and learner-centered interaction while addressing key challenges in ethical data governance, transparency, and accountability. To bridge theory and application, we outline a staged validation roadmap informed by technical feasibility assessments and stakeholder input. This roadmap lays the foundation for future prototyping and responsible deployment in real-world educational settings, positioning GEAI as a forward-looking contribution to both AI system design and education policy alignment.

This study aims to photograph, design, and digitally document the surviving residential buildings on the island of Halki (Heybeliada), within the Princes’ Islands. This documentation focuses on the architectural, urban, and historical aspects of Halki, highlighting the significant material evidence of the Greek social and economic presence. It also examines the urban cultural heritage as depicted in Turkish literature of that period to understand how Turkish writers perceived and presented Halki, referencing the Princes’ Islands only for background context. The methodology includes the collection of material from residents through bibliographic and field research conducted on Halki. Based on these findings, a mobile augmented reality (AR) application was developed using the TaleBlazer platform, designed specifically for use on Halki. The application provides a virtual tour with multimedia-supported thematic layers of architectural and historical information. Its usability and learnability were evaluated using a questionnaire completed by students. The results showed high usability, user satisfaction, and perceived value of learning, with the majority of results close to a median score of 4 out of 5. The students identified the occurrence of immersive experience, ease of use, and the emotional stimulation created by the integration of spatial storytelling and multimedia. This paper also shows how the convergence of cultural content (history, architecture, and literature) can enhance interpretations and experiences with mobile AR technologies. Full article

The most popular and/or state-of-the-art image and LiDAR data correction techniques are characterized. To develop good practice in shallow water mapping, the authors present examples of data acquired by all the mentioned technologies with selected correction methods. Full article

The present study explores the affordances of virtual reality (VR) technologies to enhance digital and media literacy skills within an interdisciplinary and inclusive K-12 English as a Foreign Language (EFL) learning context. Addressing gaps in research on the design and impact of VR experiences in secondary education, the study investigates VR affordances not only as a learning tool, but also as a medium for knowledge co-creation through learning by doing, with students acting as the agents within digital social contexts. The study was conducted for two years, with 59 participants aged 13–14 years old, following a structured five-phase intervention model with the intent to comply with DigComp 2.2 guidelines for digital citizenship and the Universal Design for Learning (UDL) for inclusive educational practices. The phases involved (a) training on the technological level to leverage digital tools; (b) media and information literacy (MIL) instruction in VR; (c) collaborative VR artifact creation; (d) peer evaluation; and (e) dissemination with peers from other sociocultural contexts for an iterative process of continuous content improvement and social discourse. Mixed methods data collection included pre/post-course surveys, pre/post-tests, observation journals, and student-generated VR artifact evaluations. The findings indicate consistent learning gains across both years, with an average pre–post gain of 18 points (Cohen’s d = −2.25; t = −17.3, p < 0.001). The VR-supported intervention fostered complex skillset building within a VR-supported dynamic learning environment that caters to diverse needs. Students’ reflections informed a framework for designing inclusive media literacy in VR, structured around three main pillars: Narrative Structure, Strategic Design, and Representation Awareness. These themes encapsulate the practical, cognitive, and ethical dimensions of VR design. Sub-themes with examples contribute to understanding the key design elements of VR in promoting participatory engagement, digital and media literacy, critical discourse, and inclusive education. The sub-themes per pillar are signaling and multisensory cues, storyline, and artful thinking; schema formation, multimedia encoding, and optimal cognitive load; and bias-free, respect for emotional impact, and language and symbols. Complementary quantitative findings confirmed the themes of the proposed framework, revealing a positive correlation between the perceived ease of use (PEoU) with digital skills development and a negative correlation between perceived usefulness (PU) and cognitive load. The study concludes with recommendations for pedagogy, curriculum design, and future research to empower learners in shaping sustainable digital futures. Full article

Symmetries and symmetry-breaking play significant roles in data security. Digital watermarking is widely employed in information security fields such as copyright protection and traceability. With the continuous advancement of technology, the research into and application of digital watermarking face numerous challenges. To gain a comprehensive understanding of the current research status and trends in the development of digital watermarking, this paper conducts a bibliometric analysis using the CiteSpace software, focusing on 8621 publications related to digital watermarking (watermark/watermarking) from the Web of Science (WOS) Core Collection database, spanning from 2004 to 2024. This study explores the research landscape and future trends in digital watermarking from various perspectives, including annual publication volume, keyword co-occurrence and burst detection, leading authors, research institutions, and publishing countries or regions. The results reveal a regional concentration of research efforts, with early research being primarily dominated by the United States, Taiwan, and South Korea, while recent years have seen a rapid rise in research from China and India. However, global academic collaboration remains relatively fragmented and lacks a well-integrated international research network. Keyword analysis indicates that research hotspots have expanded from traditional copyright protection to data integrity verification, multimedia watermarking, and the incorporation of intelligent technologies. Notably, the introduction of deep learning has propelled watermarking algorithms toward greater sophistication and intelligence. Using CiteSpace, this study is the first to systematically illustrate the dynamic evolution of digital watermarking research over the past 20 years, focusing on thematic trends and regional distributions. Unlike previous reviews that rely mainly on qualitative analyses, this study offers a quantitative and visualized perspective. These findings provide concrete references for the future development of more targeted research efforts. Full article

This study explored the integration of technology into teaching practices by examining how faculty members at a newly established university in Saudi Arabia utilized the Blackboard learning system. Specifically, it investigated the use of multimedia e-learning tools by male and female faculty members during regular teaching periods following the COVID-19 pandemic. A survey questionnaire was developed using a 5-point Likert scale. The instrument covered demographic information, content creation, assessment methods, utility tools, and factors influencing Blackboard usage. Upon receiving approval, the survey was distributed via email to all faculty members across nine colleges. A total of 198 responses were collected and analyzed using both descriptive and inferential statistical methods. The findings indicated that gender had little to no statistically significant impact on the use of key Blackboard tools—such as content creation features (e.g., files, folders, items), assessment tools (e.g., tests, assignments), and utilities (e.g., virtual classes, email)—at the college level. However, when analyzed at the university level, some tools’ usage showed statistically significant gender differences at the α = 0.05 level. Furthermore, both male and female faculty members cited convenience, flexibility in uploading materials, access to virtual classes, and remote assessment of students as primary factors influencing their e-learning preferences.

While speakers of German have adopted many loanwords from other languages throughout history, recent diversification of language use in Germany is mainly driven by the global mobility of English. Previous research has therefore focused on various domains in which English linguistic resources are used, particularly in traditional media and social media communication. Furthermore, many studies on social media communication have also examined English language internet memes more broadly. Despite this plethora of research, little attention has been paid to how English is used in internet memes and reels produced by professional journalists in Germany. Playing a significant role in communication amongst young people, internet memes and reels are used by many German youth media organisations. In particular for youth radio stations in Germany, which have become multimedia outlets, online communication via Instagram is vital for their audience interaction. This paper examines the use of English linguistic resources in a professionally produced Instagram corpus of internet meme and reel captions produced by journalists working for one of the largest youth radio stations in Germany. Data for the analysis of Instagram content were collected as part of the larger ethnographic research project CIDoRA (funded by the European Union). For this project, a mixed methods approach was applied. Methods of data collection and analysis include linguistic ethnography both at the youth radio station and on the station’s Instagram profile page, informal interviews and 20 semi-structured interviews with journalists, and a quantitative and qualitative analysis of 980 meme and reel captions produced for the station’s Instagram profile. Since the youth radio station’s Instagram profile functions as a means of the station’s online self-advertisement, the analysis of this article also draws on a previous study by the researcher. This study analysed possible facilitating factors for the use of catachrestic and non-catachrestic anglicisms in radio station imaging (radio self-advertisement) of six German adult contemporary radio stations. The article therefore includes an analysis of the possible facilitating factors lexical field, brevity of expression, diachronic development of the pragmatic value of lexical items and semantic reasons for the use of English in Instagram content. It thereby explores the differences in anglicism use between these two media formats (radio broadcasting and social media communication) and whether possible facilitating factors for the use of English in adult contemporary radio station imaging are also facilitating factors for the use of English in meme and reel captions produced by the youth radio station.

The objective of this study is to verify the usability of gesture interactions such as tilting or shaking, rather than conventional touch gestures, on mobile devices. To this end, a prototype was developed that manipulates the text size in a mobile text messaging application through tilt gestures. In the text input interface, three types of tilt gesture interaction methods (‘Shaking’, ‘Leaning’, and ‘Acceleration’) were implemented to select the text size level among five levels (extra-small, small, normal, large, and extra-large). Along with the gesture-based interaction methods, the conventional button method was also evaluated. A total of 24 participants were asked to prepare text messages of specified font sizes using randomly assigned interaction methods to select the font size. Task completion time, accuracy (setting errors and input errors), workload, and subjective preferences were collected and analyzed. As a result, the ‘Shaking’ method was generally similar to the conventional button method and superior to the other two ‘Leaning’ and ‘Acceleration’ methods. This may be because ‘Leaning’ and ‘Acceleration’ are continuous operations, while ‘Shaking’ is an individual operation for each menu (font size level). According to subjective comments, tilting gestures on mobile devices can not only be useful if users take the time to learn them, but also provide ways to convey intentions with simple text. Although tilting gestures were not found to significantly improve text editing performance compared to conventional screen touch methods, the use of motion gestures beyond touch on mobile devices can be considered for interface manipulations such as app navigation, gaming, or multimedia controls across diverse applications.

The use of mobile phones in teaching processes, in the context of technological convergence, involves considering educational intention, pedagogical tactics, and the capacity of digital media for learning. The utilization of mobile phones in the classroom gives the students instant access to a wide range of educational resources, including educational applications, specialized websites, and multimedia material. Learning to use mobile devices responsibly and productively is essential in today’s digital age, as it prepares them for future technological interactions. The present study examines the intermediary function of a mobile education application, conceived under the problem-based learning approach, in the field of mathematics. This research was carried out with a descriptive approach. A pretest, a post-test, and a survey were created and administered for the collection of numerical data, along with an observation grid for qualitative information. The results highlight the contribution of mobile devices and problem-based learning in the development of skills for collaborative work, decision-making, and problem-solving through systems of linear equations using four techniques. The conclusions highlight the potential of mobile devices in the educational field since they are a resource that provides access to information without time or location limitations. However, it is necessary to focus on the design of pedagogical strategies to carry out a pedagogical and planned use of this resource. Full article

In recent years, the increase in energy demand has been an incentive to search for new ways to generate energy. An alternative is producing this energy from daily human activities. To do this, piezoelectric devices have been used in different human activities to collect energy. Some of these potential activities are transportation, biomedicine, and electronic devices. Harvesting energy from the mechanical force applied by a pianist during their performance is one of these activities that can be used. The implementation of piezoelectric devices under the keys of an electric organ was carried out. A theoretical model was developed to estimate the amount of energy we could recover. The system was characterized by controlled forces. The volume generated by the forces was measured via a Musical Instrument Digital Interface (MIDI) using the open-source music production software “LMMS (Linux MultiMedia Studio) 1.2.2 version”. The electric potential difference was measured as a function of the volume generated by the pianist. The voltages generated for different frequencies of the pianist’s rhythm were studied. The efficiency calculated in the mathematical model agreed with that obtained in the implemented system. The study results indicate that the batteries were recharged, which resulted in 53 s of organ operation. Full article

It is important to work on educating children’s emotional intelligence, namely the re-awareness and control of emotions, both their own and those around them so that they feel empathy for others, establish and maintain positive relationships and make conscious decisions. This document describes a proposal for a gamified solution, based on the development of a multimedia product, which aims to help children, parents and teachers in the education of emotional intelligence in children. The solution makes it possible to present everyday scenarios to children, allowing adults to find out how they feel and, based on this information, to work on feelings and social behaviour. The solution was based on research into studies available in scientific databases on children’s emotional intelligence, as well as research into exercises that can help work on this same issue. Once implemented, the solution was tested with children from a primary school, where it was possible to collect feedback from them and their teachers and make improvements. This study presents the design, development and evaluation of a gamified application for children focused on emotional intelligence. The methodology used is based on a systematic literature review following the PRISMA protocol and the development of an iterative multimedia product. The study sample included around 200 elementary school children, where it was possible to collect qualitative feedback to evaluate the effectiveness of the application. The results obtained made it possible to make improvements to the design of the application and to obtain feedback from the teachers, which was very positive, but transmitted by direct interview.

The recording of metaverse experiences supports various use cases in collaboration, VR training, and more. Such Metaverse Recordings can be created as multimedia and time series data during the 3D rendering process of the audio–video stream for the user. To search in a collection of recordings, Multimedia Information Retrieval methods can be used. Also, querying and accessing Metaverse Recordings based on the recorded time series data is possible. The presentation of human-perceivable results of time-series-based Metaverse Recordings is a challenge. This paper demonstrates an approach to generating human-perceivable media from time-series-based Metaverse Recordings with the help of generative artificial intelligence. Our findings show the general feasibility of the approach and outline the current limitations and remaining challenges. Full article

Background: Social media platforms increasingly influence dietary behaviours, with cooking videos emerging as a key tool for promoting healthy eating. However, limited research has examined how such digital content affects adults in established adulthood. Objective: This study investigates the relationships among cooking behaviour, engagement with healthy cooking videos on Instagram, and healthy eating behaviours among Taiwanese adults aged 30 to 45. Methods: A cross-sectional online survey collected valid responses from 488 participants (effective response rate = 81.3%) who regularly cook and engage with food-related content on Instagram. Structural equation modelling (SEM) was used to test hypothesised relationships. Results: Cooking behaviour was positively associated with engagement in healthy cooking multimedia (β = 0.262, p < 0.01). Engagement significantly predicted healthy eating behaviours (β = 0.399, p < 0.001) and mediated the effect of cooking behaviour on dietary outcomes (indirect effect = 0.105, 95% CI [0.044, 0.204]). Cooking behaviour alone was not directly associated with healthy eating behaviours (β = 0.009, n.s.). Conclusions: Engagement with healthy cooking videos enhances healthy eating practices among adults in established adulthood. These findings highlight Instagram’s potential as a digital health promotion tool and support the integration of culinary media into public nutrition strategies. Full article

Cultural heritage significantly influences the transmission of history from the past to the present and future. The core of protecting cultural heritage is inheritance, making sure the heritages can be sustainable forever. Various ICT methods facilitate the dissemination and preservation of cultural heritage information. However, traditional ICT platforms often focus on official authority perspectives, neglecting users’ preferences for retrieving cultural heritage information. To address this, a hypothetical media platform was developed to collect people’s preferences for cultural heritage content and media types through a questionnaire, leading to the creation of a new multi-media platform. For demonstration purposes, Strijp-S, an industrial cultural heritage site in Eindhoven, the Netherlands, was used as a case study. A questionnaire was administered to test the prototype’s effectiveness and compare it with a comprehensive search engine like Google. Independent and paired-samples t-tests were conducted to analyze the results, demonstrating that the dedicated multi-media platform prototype was more effective than Google in raising awareness of Strijp-S. These findings indicate that a platform designed based on users’ preferences can enhance public awareness of cultural heritage. This approach can assist policymakers in developing platforms to promote local cultural heritage effectively. Full article
