Mobile's health care and diagnostic capabilities are accepted as the most innovative sectors, and the combination with wearable device is being predicted as the future's most promising industries. However, the level of consumer acceptance and utilization is still insufficient compared to the development of technology. This study explores the use intention of wearable device based on previous studies about health apps. In particular, health-related use efficacy of the app, app use intention and app satisfaction are analyzed through a structural equation model. The use of health-related apps revealed that there is a statistically significant relationship with the use of the wearable device. The results suggest that the importance of app use efficacy, satisfaction, apps use should be considered for the successful diffusion of wearable health devices.

Entering aging society and increasing individual's interests on wellbeing lead to increasing demands of healthcare service and various healthcare related applications are providedon app market or Internet. These healthcare services could enhance user's health status if the users continuously use the service. In order to enhance effectiveness of a healthcare service, the service user should comply with recommendations or directions are provided by the service. However, previous studies of healthcare service are not considered effects of compliance intention on continuous usage. Hence, we tested how user's compliance intention effect on continuous usage intention of healthcare service based on theories of information system and medical information. Moreover, we found that compliance intention of users for healthcare service is an important factor on sustainability of healthcare service. Additionally, we investigated what factors are related with user's compliance intention.

This study examined how the quality of TikTok service affects user satisfaction and continuance intention. This study classified the quality of Tiktok service as service quality, information quality, and system quality, and examined the effect of each dimension on user satisfaction and continuous intention. In addition, the role of perceived commercial viability was also examined. In this study, we conduced an online survey on 237 Chinese TikTok users and analyzed the data with the SEM and a moderated regression analysis. Results are as follows. First, information quality and system quality are positively associated with user satisfaction. Second, information quality is positively associated with continuance intention. Third, user satisfaction fully mediates system quality and continuance intention, and it partially mediates information quality and continuance intention. Fourth, although user satisfaction is positively associated with continuance intention, commercial viability does not function as a moderating variable.

In addition, this study was to grasp the relationship between use motivation and sustained use intention as a mediating effect of use satisfaction. The survey was conducted online and offline, 315 adolescents were selected for analysis. For the data, factor analysis, multiple regression analysis, and effect analysis of parameters were conducted using the SPSS 25 program. As a result of the study, information/entertainment pursuit, communication, and self-expression were derived as motivation for use. Among these motivations, information/enterprise pursuit and communication were found to have a significant effect on use satisfaction and continued use intention.

With a recent rise of various chatbot services, this study attempts to explore the role of chatbot users'' psychological characteristics by applying the self-determination theory. In particular,this study investigates (a) the relationship between chatbot users' psychological needs(perceived autonomy, perceived competence, perceived relatedness) and user satisfaction, continuous intention to use, and (b) the moderating effect of chatbot type and user motivations. Based upon a survey, the results revealed that perceived autonomy, competence, and relatedness had significant positive effects on user satisfaction and continuous intention to use. The results also confirmed that the user satisfaction had a significant positive effect on the continuous intention to use. The moderating effect of social and relational motivation was found between perceived autonomy, competence, relatedness and user satisfaction. The implications are discussed for furthering the development of chatbot services.

The study has been derived through the empirical analysis so as to find the Continuous Usage of Electronic Official Document 24 System. Total of 236 questionnaires were analysis to users who used or experienced the Electronic Official Document 24 System. As a result of the analysis First Accuracy, Convenience, and Security have a positive(+) effect on Ease of Use. However, Compatibility and Innovation were not effect on Ease of Use Second, Accuracy, Convenience, Security, and Innovation have a positive(+) effect on Perceived Usefulness. However, Compatibility was not effect on Perceived Usefulness. Third, Behavioral Costs have a positive(+) effect Continuous Intention and perceived ease of use positively affects perceived usefulness and Continuous Intention. Finally, perceived usefulness also has a positive effect on the Continuous Intention.

챗봇이란 인공지능 기반으로 인간과 대화하는 로봇을 일컬으며, 요청과 응답구조로 운영되는 인공지능 프로그램을 말한다. 챗봇은 사용자와 상호작용하기 위해 대화형 인터페이스를 사용하는 소프트웨어로 기존 사용자의 언어를 이해하고 학습하여 인간이 대화하듯이 대화를 하도록 설계되어있다. 챗봇을 사용하는 회사는 인건비를 줄이고 빅데이터를 기반으로 전문적이고 정확한 답변을 제공할 수 있어 활용 효율성이 높은 편이다. 그러나 회사가 챗봇을 적극적으로 도입하고 사용자에게 긍정적인 영향을 줄 것이라는 기대와 달리 사용자는 챗봇을 계속 사용하지 않고있다. 따라서 본 논문은 챗봇 서비스의 지속사용의도에 영향을 미치는 요인들을 파악하고자 한다. 특히 인공지능 특성이 챗봇 서비스 지속적 사용의도에 미치는 영향을 연구한다.

This study examined the concept and usage moderated mediating model in structural equation modeling. The theoretical model and hypothesis were developed based on the Location-Based application's Expectancy disconfirmation, Location-Based application's satisfaction, Location-Based application's continuous usage intention, service trust. The statistical results of the two model were compared: one was free model(positive/negative) and the other was the Moderated Mediating Model(positive/negative). A structure equation model analysis was carried out to test the research model. Further studies are necessary to Ssupport the research hypotheses.
