INTRODUCTION: Nowadays, lung cancer is known as one of the serious threats to human health and life globally. To deal with lung cancer, a problem is to accurately segment tumors from CT scans to help doctors in assessment and treatment planning. OBJECTIVES: This study proposes a method for segmenting lung tumors from CT scan data based on exploiting spatial information between slices to feed into the deep learning model and applying 3D volumetric post-processing. In addition, we also provide visualization of 3D tumor reconstruction data. METHODS: We incorporate spatially continuous data into the 2.5D input. In addition, we use a hybrid TransUNet deep learning model, and finally post-process 3D volumes. Our method allows the deep learning model to take advantage of spatial context information along the slices. TransUNet takes advantage of both CNN and Transformer. The 3D volume post-processing technique refines the results, removing discrete noisy blocks. This results in increased continuity and more accurate reconstruction in three-dimensional space. RESULTS: The segmentation results were satisfactory. In case of 2.5D of 3 slices, results on NSCLC-Radiomics reached the Dice over slices of 0.891 ± 0.277, the Dice over 3D volumes of 0.641 ± 0.235, the IoU over slices of 0.875 ± 0.291, the IoU over 3D volumes of 0.508 ± 0.228, False Positives of 94, and False Negatives of 224. In case of 2.5D of 5 slices, results on NSCLC-Radiogenomics reached the Dice over slices of 0.951 ± 0.186, the Dice over 3D volumes of 0.671 ± 0.231, the IoU over slices of 0.941 ± 0.200, the IoU over 3D volumes of 0.539 ± 0.223, False Positives of 8, and False Negatives of 67.. In addition, the 3D tumor visualization showed good visualization capabilities. CONCLUSION: The proposed method has proven to be effective in lung tumor segmentation. In this study, the elements of the proposed method have been analyzed comprehensively and comparatively. In the future, we expect to continue to conduct in-depth research and expand the experiment on patient data in Vietnam.
INTRODUCTION: Meaningful engagement in clinical interventions or technology-mediated activities can support the psychosocial well-being of persons living with dementia. However, meaningfulness is often assumed rather than explicitly conceptualized in both academic context and in care practice.OBJECTIVES: This review aims to examine how interventions and activity provision can support psychosocial well-being and how meaningful engagement is shaped by the conditions surrounding their provision, with particular attention to people with moderate and advanced dementia in long-term care facilities. METHODS: An integrative review was conducted through article searching in databases including PubMed, Scopus, and the ACM Digital Library dated from 2014 through 2025. In this review, 60 publications were synthesized for answering proposed objectives and questions.RESULTS: We identified six activity forms and five recurring mechanisms through which activities acquire psychosocial value and are considered meaningful. The central finding is that meaningfulness is not an inherent property of an intervention or technology-mediated activity. It was shaped by the changing relationship between the person, activity, other stakeholders, and care environment. Activities are more likely to become meaningful when they connect with the person’s identity and retained abilities, permit supported forms of agency, are facilitated within responsive relationships and workable care routines.CONCLUSION: This review advances a person-centered design agenda that shifts attention from isolated interventions toward activity-care ecosystems. It extends previous intervention- and technology-centered reviews by explaining how meaningful engagement can be co-produced, evaluated, and sustained in everyday dementia care.
INTRODUCTION: Against the background that urban sports facilities for older adults are mostly planned as isolated construction projects, with access, operation‑maintenance and digital inclusion handled as fragmented separate tasks, this paper constructs a lightweight digital optimization framework connecting multiple functional links for age‑friendly sports facilities. OBJECTIVES: To develop a lightweight digital optimization framework that links needs assessment, asset information, condition monitoring, service scheduling, and inclusive user feedback for urban sports facilities for older adults. METHODS: Comparative analysis of age‑friendly initiatives in Beijing and Singapore, six‑week pilot site experiment, counterbalanced‑order within‑subject test were adopted. The technical tools included tablet dashboard, QR‑free large‑button interface, infrared entry counter and weekly maintenance log, without cloud model training or specialized medical sensing equipment. RESULTS: A lightweight digital optimization framework covering needs assessment, asset information, condition monitoring, service scheduling and inclusive user feedback was formed, which provides explicit data fields, operating thresholds, and human fallback procedures for age‑friendly facility planning and utilization. The pilot test with 36 participants aged 60‑79 showed that, compared with routine service, the digital‑support condition yielded higher site‑use rate (63.5% vs 41.0%), longer observed activity sessions (32.8 min vs 24.6 min), higher task‑completion scores (79.4 vs 62.8), higher facility usability index (78.2 vs 61.3), and the mean maintenance response time decreased from 3.6 days to 1.9 days. CONCLUSION: The proposed lightweight digital framework can effectively improve site utilization, user task‑completion performance, facility usability and maintenance efficiency of urban sports facilities for older adults, offering operable reference for age‑friendly facility planning and daily operation.
INTRODUCTION: Persuasive technology offers a technological approach to promote physical activity. OBJECTIVES: This study aims to design and evaluate user perceptions of various persuasive strategies in a wearable system. METHODS: Six persuasive strategies were implemented in a wearable system comprising a sensing strap, an Android application, and a data server. A pilot user study assessed perceived persuasive efficacy via post-study questionnaires and diaries. RESULTS: The findings indicated that social influence, goal setting, and reinforcement significantly correlated with persuasive efficacy; personal awareness, enjoyment interaction, and suggestion and reminders did not. All six strategies significantly increased sustained usage intention. CONCLUSION: A multi-strategy persuasive wearable system can enhance sustained usage intention and exercise motivation, with complementary roles of different strategies, demonstrating its potential for health behavior interventions.
Rural primary schools in mountainous areas often lack safe, versatile, and maintainable sports equipment because commercial systems are expensive to transport and install. This paper develops a low-cost corrugated paper-bamboo facility system in which corrugated board is used for replaceable, non-primary load panels and locally available bamboo forms the reusable frame. The design method combines a 95-response user survey, a constraint-based product specification, module-level prototype screening, and a four-week feasibility crossover with 24 pupils. Five modules were prototyped for throwing, target practice, coordination, and group games. For the most critical balance-rail assembly, the nominal design load was 1.20 kN, the measured maximum service load was 1.84 kN, and the failure load was 4.07 kN, giving a calculated ratio of 2.21; the values refer to different load definitions and are reported separately. The selected reference purchase price for a five-function commercial package was 5,470 RMB; the prototype material cost was 1,186 RMB and the full delivered prototype estimate was 1,744 RMB. During the pilot, the kit condition was associated with higher observed active-play time (27.9 versus 18.6 min per lesson) and task completion (81.6% versus 62.4%). Internal screening was designed with reference to selected criteria in ISO 8124-1 and EN 1176-1; it was not third-party certification. Use is limited to supervised, protected, low-load activities with daily inspection and replacement rules.
