Mobile TV refers to the service that provides live broadcasting and video-on-demand content through a mobile device. In addition to the advertisement as the early-stage revenue model, the paid subscription model has emerged as a more sustainable revenue source for mobile TV services. In this study, with the surveys of 450 free mobile TV users, we examine the motivational factors influencing their intention to adopt a paid subscription model. Results show that three extrinsic motivations, price fairness, subjective norm, and mobile TV utilization, are positively associated with free users' paid subscription intention. In contrast, intrinsic motivations, such as hedonic need, spatiotemporal convenience, and self-efficacy, have no significant influence on the intention. We also found that the expected value is positively associated with attitude toward mobile TV service, also positively influencing the paid subscription intention.

The primary aim of this study was to examine how various factors influence university students' intention to use ChatGPT for educational purposes and to analyze the structural relationships between these factors. Specifically, the study investigated Social Mood and Self-Efficacy as exogenous variables, while considering Confirmation, Task Technology Fit, and Satisfaction as mediating variables, and Intention to Use as the dependent variable. Data were collected from 261 students at two universities in the Seoul metropolitan area of South Korea, and structural equation modeling was employed to analyze the impact of each variable on the Intention to Use and the interrelationships among the variables. The study found that ChatGPT partially meets the educational expectations of Korean university students. It was observed that Confirmation, which is influenced by Social Mood and Self-Efficacy, significantly affects the intention to use ChatGPT. Additionally, Satisfaction has a direct and significant influence on students' intention to use ChatGPT, indicating that the level of satisfaction with ChatGPT plays a crucial role in their continued usage. Moreover, Social Mood and Self-Efficacy were found to indirectly influence the intention to use ChatGPT through mediators such as Confirmation, Task Technology Fit, and Satisfaction. These findings highlight the complex interplay between these variables and their impact on students' usage of ChatGPT, providing valuable insights into the factors that drive its educational use.

Introduction : This review aims to introduce an intention-to-treat analysis(ITT) method and demonstrate the importance of rigorous utilization of this method to researchers in Korea. Discussion : ITT analysis includes all data as results in randomized control trials (RCT). Thereby the result of RCT is high validated to adapt in the real-world so that the result should be expected at clinical practice. Therefore, many RCT quality assessment tools include the question of the utilization of ITT analysis in individual trials. However, many researchers omit to report ITT, not utilize ITT or use ITT incorrectly. Conclusion : Through this review, more Korean researchers may understand and utilize ITT which is expected to enhance the quality of RCT papers.

Background: Although a direct association has been established between oral health management and maintaining military combat readiness and fulfilling defense duties, unmet dental-care needs have been consistently reported, and there has been little research on the role of mobile healthcare services in addressing this issue. This study explored the association between unmet dental-care needs and the intention to use mobile healthcare services among military personnel. Methods: This study was conducted on military personnel who visited a military hospital in Gyeonggi-do, Korea, from August 19 to August 31, 2024. A total of 150 self-administered questionnaires were distributed and 135 valid responses were analyzed. The analysis included general characteristics, dental care utilization, and intention to use mobile healthcare services. Statistical analyses, such as t-tests, ANOVA, and multiple regression, were employed to determine the factors influencing the intention to use mobile healthcare services. Results: This study found that military personnel with unmet dental-care needs had significantly higher intentions to use mobile healthcare services than those without such needs. The analysis revealed that the key factors influencing this intention were perceived health status and previous dental-care utilization. Specifically, participants who rated their overall health as better and those who had used dental care services in the past year showed a greater tendency to express interest in mobile healthcare services than those who did not. Furthermore, unmet dental-care needs were more prevalent among soldiers who reported limited access to dental facilities owing to time constraints or a lack of prioritization of oral health, which increased their inclination toward utilizing mobile healthcare solutions as an alternative. Conclusion: Mobile healthcare solutions can offer personalized and timely care as viable alternatives for improving oral health management in the military. Moreover, integrating mobile healthcare services into military health systems could significantly reduce unmet dental-care needs and enhance overall combat readiness by promoting better health outcomes.

We question whether Korean IT managers consider real options to reduce risks of cloud service implementation. This work investigates the impact of technology risk, relationship risk, economy risk, security risk upon the intention of IT managers to utilize abandon & expansion options. We also analyze moderation effect of centralization level of decision making between these risks and the utilization of real options. Using the survey questionnaire, we empirically find that technology risk, relationship risk and security risk have significant effect upon abandon option and technology risk, relationship risk, and economy upon expansion option. We also find the evidence that centralization level moderates some risks and the direction of moderation effect is to offset the effect of risks on intention to utilize real options.
