Studying for self-development is a lifelong necessity, regardless of age, for students, office workers, and individuals in all walks of life. Recently, trends such as measuring personal study time with a stopwatch and sharing it on social media, or participating in live “Study With Me” sessions on YouTube, have gained popularity. These practices help reduce the sense of isolation in solo studying and foster motivation through shared experiences and a sense of community. In this paper, we developed a web-based platform that allows users to track their study time in real time and visualize the data through various statistics. This system helps individuals manage their study schedules more efficiently and encourages better time management. In addition, users can simulate the experience of studying with others through group study features, which adds a sense of companionship during study sessions. A daily ranking system based on total study time adds a competitive element that may motivate users to study longer and more consistently. Furthermore, the platform includes a bulletin board where users can exchange study tips, share useful resources, and discuss certification-related information. This creates an active community and enhances the overall learning experience through peer interaction. Future enhancements may include a mobile application and personalized feedback features tailored to specific study areas, aiming to meet a wider range of user needs and preferences.

This qualitative case study analyzes the practices and factors that influence the transparency of the management of the Sidodadi Village Fund. Data was collected through semi-structured interviews, observations, and analysis of budget documents (APBDes, RKPDes, LPJDes, LRA). The results show that transparency is implemented through formal mechanisms such as village meetings and bulletin boards, as well as informal channels such as social gatherings of village officials and communication at the sub-district level to reach hamlets. The findings identify factors that hinder effectiveness, namely regulatory restrictions on cost details, limitations in technology and human resources of the village apparatus, and variations in the information literacy of the community. This study concludes that although an information disclosure framework exists, residents’ substantive understanding of budget allocation remains limited. The empirical contribution of this research is the mapping of the role of informal channels in supporting transparency when digital means are not yet optimal, as well as the identification of regulatory restrictions that limit the depth of budget information disclosed. Furthermore, this study describes the interaction between formal procedures and social communication networks that shape access to information in rural environments. These findings form the basis for the development of adaptive and inclusive transparency strategies for rural contexts with varying levels of technological capacity and public literacy.

Introduction:Given the important role of motor imagery (MI) in rehabilitation, this study aimed to compare MI abilities in individuals with spastic diplegic cerebral palsy (SDCP) and typically-developing (TD), and to determine the factors associated with MI ability in SDCP.Patients and Methods:This study was planned as a cross-sectional, case-control study. SDCP (n = 26) and TD (n = 26) individuals participated in the study. SDCP individuals were selected from Special Education and Rehabilitation Centers, while TD participants were recruited from relatives of patients receiving therapy at these centers and from volunteers responding to bulletin board announcements. All assessments were performed before or after the weekly physiotherapy sessions, to avoid interfering with routine physiotherapy and rehabilitation sessions. Visual and kinesthetic imagery abilities were assessed using the Movement imagery questionnaire for children (MIQ-C), Implicit MI capacity laterality task, and Explicit MI capacity mental chronometry.Results:The SDCP group had a mean age of 11.69 (3.78) years, consisting of 12 females and 14 males; 10 participants were classified as Gross Motor Function Classification System (GMFCS) Level I and 16 as Level II. The TD group had a mean age of 11.50 (2.30) years, including 16 females and 10 males. A significant difference was found between the groups in MIQ-C and mental chronometry performance (p < 0.05). While there was a significant difference in reaction time according to dominance in SDCP (p = 0.038), there was no difference in accuracy rate (p = 0.699). Reaction time and accuracy rate were significantly different between groups according to dominance (p < 0.05). There was no correlation between MIQ-C total score, dominant reaction time and accuracy rate and age, Body Mass Index (BMI), and GMFCS (p > 0.05). While age and BMI were not related to mental chronometry; GMFCS was found to have a significant positive effect on mental chronometry (p = 0.000).Conclusions:In children with SDCP MI ability differs from that of typically developing peers, being weaker across all assessed subparameters. Moreover, MI ability showed a moderate association with the GMFCS level.

In a bustling college campus environment, the loss and misplacement of personal belongings is a frequent and often frustrating experience for students, faculty, and staff. Items such as mobile phones, ID cards, books, and accessories are commonly left behind in classrooms, libraries, cafeterias, and hostels. Traditional lost-and-found systems, typically reliant on manual logs or bulletin boards, are inefficient and lack real-time communication, making the recovery process slow and unreliable. To address this issue, we propose a mobile application specifically designed to streamline the management of lost and found items within a college campus. This application provides a centralized digital platform where users can report lost items by submitting detailed descriptions, images, and the location where the item was last seen. Likewise, individuals who find items can upload relevant information to help identify and return them to their rightful owners. The app utilizes location-based services to match lost and found reports within specific campus zones, increasing the likelihood of successful recovery. Key features include secure messaging, user verification, item categorization, and real-time notifications. Integration with campus security and administrative offices allows for digital tracking of items turned in at official locations, enhancing coordination and accessibility. By leveraging mobile technology and fostering collaboration within the campus community, this application offers a modern, efficient, and secure solution to the problem of lost and found items. It promotes responsible behavior, reduces recovery time, and strengthens community engagement, making it a valuable tool for everyday campus life.

The Wali Nagari Office of Simalidu continues to face challenges in disseminating information due to the lack of an official digital platform. Information is currently delivered manually via bulletin boards, limiting public access and reducing efficiency. This study aims to design and develop a website-based information system for the Wali Nagari Office of Simalidu to improve communication effectiveness between the local government and the community. The research applies the Waterfall method, starting from requirements analysis, system design, implementation, and system testing. The system was developed using the PHP programming language and MySQL database. The main features include a homepage, a village profile, news/information, activities, employee data, a message page, and a contact page. System testing was conducted using the Blackbox Testing method to ensure that all functions operate as expected. The results show that the website-based information system enables village officials to deliver information quickly, accurately, and effectively to the public. It also allows the community to easily access up-to-date information regarding activities, profiles, and services at the Wali Nagari Office of Simalidu. Thus, this system improves transparency, accountability, and the quality of public services.

BackgroundOlder people are particularly vulnerable to loneliness and social isolation due to common age-related changes. The ability to maintain social relationships is considered important for health and well-being and is an essential aspect of healthy aging. The use of information and communication technology has been shown to promote social connectedness and social support among older people; however, many existing solutions require already established contacts and are not developed based on expressed needs among older people experiencing loneliness or social isolation.ObjectiveThe overarching aim of this study was to develop a prototype of a health and welfare technology intervention for decreasing loneliness and social isolation among older people.MethodsThis study describes an iterative participatory design process conducted in 3 phases to create a prototype of a digital intervention for decreasing loneliness and social isolation in older people through participatory design procedures with several key stakeholders. Phase I explored social service staff’s perceptions of how social isolation and experiences of loneliness among older people can be reduced by health and welfare technology. Data were collected by conducting 2 workshops (WSs) with social service staff. Phase II explored needs related to loneliness and social isolation perceived by older people and how these needs may be targeted by using health and welfare technology. Data were collected through 2 semistructured interviews and 2 WSs. In phase III, 3 co-design WSs brought together older people with experience of loneliness or social isolation, social service staff, and IT experts to collaboratively generate and refine design ideas.ResultsThe main result of the study was the development of a paper prototype of the Fik@ room, which is a digital solution supporting social interaction among older people experiencing loneliness or social isolation. Key needs identified include the desire for low-threshold opportunities to connect, flexible modes of communication, and a safe and welcoming environment. These needs directly informed the final design. The main feature of the prototype is to facilitate social interaction in a digital break room with coffee tables where users can interact via video, audio, or chat. Other features are a bulletin board for announcements about interactions inside or outside of the Fik@ room, as well as a profile page.ConclusionsThe iterative co-design process ensured that the solution was grounded in user needs, which may have contributed to the usability and acceptability of the Fik@ room and potentially effective in reducing loneliness and social isolation among older people. Future research should focus on evaluating effects in a real-world setting.

The 21st century has seen unprecedented advances in disruptive educational technologies. However, many tertiary institutions in Nigeria still rely on traditional paper-based methods for communicating vital information to students. This practice, which includes printing results on bulletin boards or sharing them on social media, often violates data privacy and protection laws. Furthermore, students can suffer psychological distress from bullying and are frequently misinformed due to the spread of disinformation. To address these critical issues, an Android mobile application called GuideMe was developed. The development followed the Staircase model lifecycle, which included needs assessment, app design, development, usability testing, evaluation, and deployment. The usability tests and evaluation confirmed the success of the GuideMe application, as evidenced by high task completion rates and favorable System Usability Scale (SUS) scores for its key functionalities.

This study designs a web-based church announcement board system using the Waterfall method to improve communication effectiveness compared to physical bulletin boards. The system was developed using PHP, MySQL, HTML, CSS, and JavaScript through stages of requirement analysis, design, implementation, and black box testing. It introduces features for uploading weekly bulletins and dynamic announcement management, accessible directly by church members via a browser. The implementation results show a reduction in announcement publishing time from 2 hours to 4 minutes and a 75% decrease in administrative workload. Black box testing on 7 scenarios confirmed that all core features, such as login, announcement management, and bulletin uploads, functioned as expected. The page load time averaged 1.2 seconds, with responsive performance on mobile devices and a p95 response time of 480 ms for 100 concurrent users. This study contributes to the digitalization of church information, providing a more efficient, interactive, and real-time system, thereby enhancing information accessibility for the congregation.

The development of digital technology presents opportunities to improve public services at the village level. Hamparan Perak Village faces challenges in delivering information, which still relies on bulletin boards, long wait times at the village office for mail administration and limited communication channels for residents to submit reports or complaints. To address these challenges, the multiplatform Smartdesa application was developed with a crowdsourcing reporting feature. Residents can submit reports and vote on other reports to prioritize their handling. The application was built using React Native for Android and Next.js for the web admin system, with Express.js as the backend, MySQL as the database, and JavaScript as the programming language. Testing results show that the application accelerates report processing and encourages active community participation in digital village management. Several obstacles were also identified, such as limited digital literacy among some users and sometimes unstable internet connections. Nevertheless, the Smartdesa application shows great potential for implementation in other villages as part of e-Government or smart village initiatives.

This study analyzes the use of digital technologies in a project aimed at strengthening local capacities in native language research in the department of Vaupés, Colombia. Using an interdisciplinary approach, we developed several digital resources, including a digital research repository, a bulletin board, a web page, and multimedia content in the native language and Spanish. Inspired by the concept of technological practice, we argue that technology can enhance native language safeguarding processes if it is viewed as a system involving technical, organizational, and cultural aspects. Related concepts such as social appropriation of knowledge and scientific communication were implemented to work on organizational and cultural aspects, through transmedia content, and address communication needs in a multilingual and culturally diverse territory. This work contributes to showing how technologies as a practice can provide technically robust, culturally appropriate, and sustainable solutions.

The literacy movement in Indonesia is currently being intensively promoted to increase students' interest in reading and writing within the school environment. Literacy habits, such as enjoying reading and writing, can improve the quality of life and elevate a person’s status. This research aimed to explain students’ perceptions or responses related to the implementation of the reading and writing literacy movement, which has been integrated into schools through various activities such as Friday Literacy Activities, the Readathon, Reading Corners Establishment, Collaborative Writing, and School Bulletin Boards and Wall Magazines. A qualitative case study design was adopted, with data obtained from questionnaire scores. The subjects comprised 247 students from two senior high schools in Surakarta that actively implemented literacy movement programs. The data collection process involved questionnaires and in-depth interviews, while data were analyzed using an interactive analysis model to ensure thematic depth and contextual accuracy. The findings indicate that students showed greater enthusiasm toward reading-related activities compared to those involving writing tasks, which were often perceived as more demanding. Nevertheless, the overall student response to the literacy programs was positive, particularly when schools provided adequate facilities and recognition for active participation. The results suggest that literacy programs should be implemented in a more sustainable and diversified manner to increase student motivation and engagement. Furthermore, institutional support through infrastructure, rewards, and collaborative initiatives with external stakeholders can significantly contribute to fostering a strong literacy culture. These findings underscore the importance of designing literacy programs that are not only curriculum-integrated but also responsive to students’ interests and needs, ultimately supporting their academic and personal development.

Bullying is one of the serious problems that occur in the school environment and can have a negative impact on the social and emotional development of students. This study aims to analyze the effectiveness of mading as an educational medium in efforts to prevent bullying in SD Muhammadiyah IV Pekanbaru. The method used is qualitative descriptive with a participatory approach, where KKN-DIK students not only observe the phenomenon of bullying, but also participate in prevention activities through making mading. The data used in this study consisted of primary data and secondary data. The data collection technique in this study was carried out by observation to see student interactions before and after the presence of mading, interviews with students and teachers to evaluate the understanding and effectiveness of mading, as well as documentation in the form of photos and videos as evidence of program implementation. The research findings show that bulletin boards are effective in increasing students' awareness about bullying, helping them better understand its forms, impacts, and ways to prevent it.

ObjectiveLife-space mobility reflects daily and social movement, crucial for active aging and independence in older adults. Good mobility is associated with greater vitality and the ability to live independently. This study examines the relationship between hearing loss and life-space mobility using pure tone average (PTA) hearing levels.MethodsThis cross-sectional study recruited participants aged 50–79 from January 2023 to May 2024 through community in southern Taiwan. Participants were recruited via electronic bulletin boards and word-of-mouth. Hearing was assessed using pure tone audiometry, and data on socioeconomic status, life-space mobility, cognition, depression, social frailty, and health status were collected via questionnaires. Logistic regression was used to identify predictors of life-space mobility.ResultsNinety participants (mean age 64.21 years) with good cognition completed the study. Pure tone audiometry showed 60% had bilateral hearing loss (better ear hearing level >20 dB), and 15.6% had bilateral hearing disability (bilateral hearing level >50 dB). Low life-space mobility was observed in 5.6%, and social frailty in 13.3%. Bilateral hearing disabilities predicted low life-space mobility (OR = 48.34, CI = 2.06–1136.35). Each decibel increase in worse ear hearing level increased the likelihood of low life-space mobility by 6% (OR = 1.06, CI = 1.0–1.1).ConclusionHearing loss is an independent predictor of life-space mobility. Increased worse ear hearing levels are associated with reduced life-space. Routine hearing assessment may support timely identification and intervention to preserve mobility in aging populations.
