Through an extensive analysis of various datasets and machine learning models, including Support Vector Regression (SVR), Gradient Boosting Decision Tree (GBDT), Linear Regression (LR), Random Forest (RF), Stacking, and XGBoost, the research evaluated predictive capabilities and explanatory power across different scenarios. Findings revealed the importance of socioeconomic and environmental factors such as household income, air pollution levels, education-related variables, household expenses, and healthcare in predicting NCD occurrence or progression. While SVR occasionally exhibited lower Mean Absolute Error (MAE), it struggled with poor explanatory power, as evidenced by negative or low R-squared and Adjusted R-squared values. Other models, particularly GBDT, RF, and XGBoost, consistently demonstrated superior predictive accuracy and moderate to better explanatory capabilities across various scenarios. The study highlighted challenges including dataset discrepancies, lack of data granularity, and the need for more detailed features, urging future research to address these limitations. Further exploration of additional SDH, incorporation of advanced machine learning techniques, longitudinal studies, and expansion of datasets to include larger and more diverse populations were suggested for improving predictive models' accuracy and explanatory power. These insights offered valuable guidance for healthcare practitioners and policymakers in devising evidence-based strategies to mitigate NCD's impact on public health.

This research aims to develop a User Experience (UX) design framework for Virtual Reality (VR) systems that facilitate movement stimulation in older adults while considering their physical, psychological, and technological accessibility limitations. The study investigates key factors influencing VR usability among elderly users and develops a prototype VR game incorporating the proposed UX design framework. The prototype is then tested with a sample group of older adults, followed by an evaluation of their user experience and satisfaction levels. The findings indicate that Accessibility, Clear Guidance, Cognitive Load Reduction, and an Engaging Environment are essential design principles that significantly enhance the usability of VR systems for the elderly. By integrating these elements, VR can effectively stimulate physical movement while ensuring ease of use. The developed UX design framework serves as a guideline for VR developers to create more inclusive and effective systems for older adults in the future.

It was found to be mainly confirmed by cohesion, reputation, and timeliness of the information. The tools used in this study were quantitative questionnaires and qualitative interviews. 275 members of the association listened to questionnaires and answered online questionnaires. In addition, the sample size of interviews for this study is 6 members from TYCC for 10 years and 4 marketing managers from Woei Hao Company. The percentage and descriptive statistics of the questionnaires were analyzed by SPSS, and multiple linear regression analysis was adopted. The results show the main factors affecting Woei Hao. This study can guide the development of member enterprises of the Chamber of Commerce and also form a more tacit relationship between enterprises and chambers of commerce.

The three independent variables investigated are leadership styles—specifically democratic (participative), authoritative, and transactional leadership; organizational learning—encompassing training and development programs, knowledge sharing and collaboration, and continuous improvement and learning culture; and organizational communication—focused on communication channel, communication quality, and employee feedback mechanisms. The study aims to understand how these factors contribute to enhancing employee engagement within organizations. Primary data were collected from 310 respondents in Thailand using a convenient sampling method. Participants completed online questionnaires consisting of demographic questions and items rated on a five-point Likert scale, addressing aspects related to the independent and dependent variables. Data analysis employed descriptive statistics and multiple linear regression techniques to assess the relationships between the independent variables and employee organizational engagement. The findings reveal significant positive impacts of all three independent variables—leadership styles, organizational learning initiatives, and organizational communication practices—on employee organizational engagement. Specifically, democratic leadership fosters participatory decision-making and inclusivity, authoritative leadership provides clear direction and alignment, and transactional leadership establishes structured performance expectations. Training and development programs enhance employee skills and adaptability, knowledge sharing and collaboration promote innovation and teamwork, and continuous improvement initiatives foster a culture of learning and adaptation. Effective communication channels, high-quality communication practices, and robust employee feedback mechanisms enhance transparency, trust, and responsiveness within organizations. This study recommends that organizations prioritize leadership development across diverse styles, invest in comprehensive learning initiatives, and strengthen communication strategies to boost employee engagement effectively. Such strategic enhancements can significantly contribute to organizational success and sustainability by aligning employee efforts with organizational goals and fostering a positive work environment conducive to growth and innovation.
