Users of Smartphone in Korea are using the majority of the economically active population over 99% and experts have seen that they have reached saturation after the initial formation stages. The purpose of this study is to investigate the influencing factors of dominant design attributes on the intention of continuous use of Smartphone users. Predictor factors were selected perceived usefulness and perceived ease of use suggested on extended the technology acceptance model. The concept model was completed by selecting the dominant design attribute as a mediator. Participants of this study were 150 Smartphone users in Busan Gyeongnam and Iksan Jeonbuk province in accordance with convenience sampling. IBM SPSS Statistics 19 were employed for descriptive statistics, Smart PLS (partial least squares) was employed for confirmatory factor analysis and path analysis of casual relationship among variables and effect. Analytical results show that all paths of continue usage intention are significant. This study suggests practical and theoretical implications based on the results.

This study tried to investigate the effect of the service quality attributes of the curation on the satisfaction, trust, and intention to continuous use of consumers in that curation services are derived in various forms and being greatly activated, there are not many academic discussions centered on them. Besides, differences between curation services by each service provider were also verified in this study. Data collection was conducted for one month in August 2019, with 373 men and women in their 20s. The results of the study are as follows. First, according to the result of investigating the variables that make effect on user satisfaction of curation service, it was identified that satisfaction has increased when figures of fulfillment, responsiveness, personalization, design, ease of use, and safety were higher. Second, among the variables that influence the reliability of the curation service, trust increases when user satisfaction, design, ease of use, and safety are higher. Third, satisfaction has a positive effect on trust, and both satisfaction and reliability affect the intention to continue use. Fourth, as a result of examining the difference in quality between the curation services divided by Curating subject, it was found that satisfaction, ubiquitous connectivity, and responsive quality were measured higher in the business operator service than in the user curation service.

This study approaches the subject of satisfaction and persistent use intention based on presence based on virtual reality (VR). VR presence, user characteristic, and VR sickness, content satisfaction and system satisfaction, and continued use intention through this of 569 men and women commissioned by the survey agency were investigated. In the content of the study, the constituent factors of VR presence, an independent variable, were set as realism, immersion, and interaction. The user characteristics were set as the individual 's propensity to innovate, the degree of immersion, and the experience of using VR. VR Presence, User Characteristics, VR Sickness of Intention of Continuous Usage were set as research problems and models. Eight hypotheses were adopted in the analysis of the research problem applying the structural equation modeling (SEM) model. In conclusion, this study suggests that content satisfaction, which has the greatest influence on VR content satisfaction and persistent intention, is suggested.

This study empirically analyzed the effects of immersion and self-efficacy on the intention to continuously use realistic media. To this end, we used an extended technology acceptance model that includes not only the perceived ease of use and usefulness, but also the perceived joy as important factors. We collected data from 595 participants through an online questionnaire survey and tested the research model using a covariance-based SEM. As a result, we found that a user's immersion significantly increased perceived usefulness, ease of use, and joy of realistic media; and self-efficacy increased perceived usefulness and ease of use. Although the effect of perceived usefulness was relatively stronger than that of perceived joy, we found that the effect of perceived joy on the intention to use was also quite large. The effect of perceived ease of use on intention to use was found to be completely mediated by perceived usefulness and joy. In addition, the differences according to the types of media were tested by comparing two groups: augmented reality and virtual reality. The effects of perceived ease, usefulness, and joy on the intention to use were very similar regardless of the type of immersive media. However, it was found that self-efficacy increases usefulness only in augmented reality. Based on our findings, we have discussed the implications of our study, as well as the scope for future research.

The purpose of this study is to analyze the relationship between tourist 's intention to use smartphone and the preceding factors through the questionnaire. For achieving this research purpose, this study surveyed the tourists who use smartphone to investigate the influence of interactivity such as two-way communication and synchronicity as hypotheses on the influence of flow, and the effect of attitude factors on continuous intention to use was analyzed by research model. In this study, a partial least squares based structural equation (PLS-SEM) method was applied to verify the hypothesis of the proposed research model. Finally, the validity of the proposed research model was confirmed through confirmatory factor analysis and hypothesis testing. Therefore, the results of this study show that interactivity and flow are influential for the reuse of users in utilizing information by using smartphone, and it affects the attitude of users in developing smart tourism system in the future. The results of this study can be utilized as basic data related to the acquisition of information by smartphone of tourists in the future development of smart tourism system.

Continuous use of SNS with having SNS fatigue influences users mentally as well as physically. Although it is reported that they eventually leave SNS due to experience of fatigue, the determinants of SNS fatigue have not been discovered yet. Thus this study aims to find the psychological factors causing SNS fatigue. This study (1) found out the factors causing SNS fatigue, and (2) explored the relationships between the factors and intentions to discontinue/continue to use SNS. Findings of the study suggested that there are seven types of determinants: Sense of relative deprivation, Relationship concern, Management burden, Information overload, Privacy concern, Reputation concern(after posting), Reputation concern(before posting). It is also found that sense of relative deprivation negatively predicted the intention to keep using SNS while management burden, reputation concern(before posting) predicted positively. Furthermore, the sense of relative deprivation and information overload positively predicted the intention to discontinue using SNS while reputation concern(before posting) predicted negatively. This research examined how the determinants of SNS fatigue affect the intentions to keep/stop using SNS from the two different points of view. The determinants of SNS fatigue experienced by SNS viewers influenced them to have intentions to stop using it, whereas those felt by SNS writers affected them to keep using it.

Purpose: The application of IoT is finding continuous acceptance in our daily lives, particularly, smart speakers are making life easier and convenient for consumers. This research aims to develop and test an integrated model of factors influencing consumer's adoption of voice-enabled IoT devices. Design/methodology/approach: Based on the VAM, an integrated voice-enabled IoT device adoption model is proposed. Gender differences on five constructs relating with perceived value (perceived usefulness, perceived enjoyment, perceived security risk, perceived technicality and perceived cost) was also examined through PLS-MGA technique. The usage experience of consumers was also controlled in the integrated VAM. Findings: Result shows that Perceived-Usefulness, Perceived-Enjoyment and Perceived-Cost have a strong effect on Perceived-Value. However, Perceived-Technicality and Perceived-Security-Risk are non-influential and have no significant effect on PV. Additionally, Perceived-Value and Social-Influence plays a significant role in predicting adoption intention. Gender differences also exist in consumers perception of usefulness, enjoyment and cost. In comparison to the basic value-based adoption model, the integrated model provides more insight on consumers adoption of voice-enabled IoT devices. Originality/value: Using an integrated model, this study is one of the first scholarly attempt at modelling the influential factors for adopting smart speakers i.e., voice-enabled IoT devices, with implications for improved adoption.

Social scientists have studied interaction between human beings, while computer scientists have expanded the research domain from human-human to human-machine, human-agent, or machine-machine. The reason why an adoption of Smart Work is failed is an anxiety about ICT usage which middle managers have. It is important to explore the concept both to reduce an anxiety on an application and to increase continuance to use it. Therefore this study takes "empathy" as a key factor to play a leading role both to relieve the anxiety about the application and to improve the intention to use it. The data is gathered from a survey of undergraduate who have experience to use MS-Access. The findings show that application empathy decrease the application anxiety, but the empathy increase the continuance mediated by cognitive and affective attitude.

With the growth of the Korean Wave and the importance of the fandom economy, it is necessary to consider the competitiveness of the Korean Wave with its fandom viewpoint. Particularly, the fandom phenomenon shows the characteristics of identifying the favorite star and actively acquiring and sharing related information in the fan community. Therefore, in this study, we examined the influence of Korean national image on consumers' intention to use Korean contents, and examined the mediating effects of fandom identification among Chinese, Japanese and Vietnamese consumers. As a result of the empirical analysis, cultural image, corporate image, and product image were found to have statistically significant influence on the intention to use Korean Wave contents. In addition, star identification and pan community identification showed partial mediation in the effect of cultural images on the intention to use Korean contents. The results of this study suggest that the Korean Wave is a leading factor for the continuous development of Korean Wave, not the halo effect point for improving the national image, and the mediating effect of the fandom phenomenon is tested empirically.
