This research is a study on smart homes products, which interest and research are being conducted, because of the recent development of the Internet of Things. Consumer's Purchase intention was set as a dependent variable, and technological trust was used as a mediating variable. We used Technology Acceptance Model as background theory. Perceived ease of use, Perceived usefulness, Security, and Brand were set as independent variables. The results of this study are as follows. First, it was found that perceived ease of use, perceived usefulness, and security significantly affected technological trust that consumers feel. Second, technological trust also had a significant effect on purchase intention, and it was found that perceived ease of use, perceived usefulness, and product security, excluding brands, had an indirect mediating effect on consumers' purchase intention through technological trust. This study is meaningful in that by conducting user-centered research, and results that are partially contrasted with existing studies are derived from increasing the interest of factors we used.

Technology acceptance model(TAM) has been widely used to predict the end-user's acceptance of a new IT/IS. We used TAM as a theoretical foundation to explain user's intention to use an Internet shopping mall. The theoretical model is tested with the questionnaires from 308 users of an Internet shopping mall. Results show that several individual characteristics such as Internet skills and self-efficacy have a significant impact on user's perception of usefulness and ease of use. Results also show that both perceived enjoyment and perceived usefulness of Internet shopping mall strongly predict intention to use the Internet shopping mall. However, perceived ease of use has no direct influence on intention to use the Internet shopping mall. Personal innovativeness and Internet skills also have a positive effect on perceived enjoyment. Therefore, Internet shopping mall managers have to consider intrinsic motivational factor(enjoyment) as well as extrinsic motivational factor(usefulness). In addition, individual characteristics should be emphasized to form the positive beliefs about using the Internet shopping mall.

With the increased importance of groupware in organizations, groupware acceptance is regarded as an important outcome in the efforts of firms to leverage the potential of this information technology in their business activities and strategies. Despite significant investments in groupware, considerable diversity exists in how well firms have been able to implement groupware and leverage the business value of groupware. This study identifies important factors influencing user acceptance of groupware by extending TAM(Technology Acceptance Model) which includes perceived control, intrinsic motivation, and concentration as well as perceived ease of use and perceived usefulness from original TAM. The proposed model is tested in an organization among 104 employees using previous research measurements. According to the findings from the study, the usage intention of groupware can be explained by intrinsic motivation, perceived control, perceived ease of use, and Perceived usefulness. However, it fails to explain the effect of concentration on the intention.

As the smart phone devices gain popularity, companies no longer consider mobile application marketing as an auxiliary marketing tactic. The branded mobile application (branded app) becomes an important part of marketing strategies. This study is an attempt to investigate antecedents of the use intention of the branded app from the perspective of TAM (Technology Acceptance Model). This study takes a macro perspective in explaining the adoption process by incorporating a set of new, yet promising additional variables into the TAM model such as flow experience, benefits, innovation inclination, and customization features. Data were collected by using a survey research. A total of 270 responses were collected. Questionnaires from 25 individuals were removed from the data set due to the insincere responses, leaving the final sample size of 245. Findings support all but one hypotheses of the study. Both perceived utilitarian benefits and customization features of the branded app were found to have positive influences on the perceived usefulness of the branded app. Also, the innovation inclination and perceived entertainment of branded app users showed positive influences on the perceived ease of use of branded app. In addition, it was shown that the perceived usefulness about the use of the branded app influenced positively the flow experience and the users' attitudes toward branded app. Also, the ease of use perceived by branded app users had positive influences on the perceived usefulness and the user's attitude toward branded app. However, the ease of use of branded app did not have a significant influence on the flow experience among users. Moreover, the flow experience from the use of branded app users influenced positively the user's attitude toward branded app. Finally, the users' attitudes toward branded app had positive influences on their intention to use the branded app. Implications for practitioners and academicians are provided.

본 연구는 지상파 UHD 방송에 대한 인지된 유용성과 용이성이 시청태도 및 의향에 얼마나 영향을 미치는 지 알아보기 위해 외생변인으로 혁신성, 상대적 이점, 몰입도, 접근성 및 친화성을 사용하였으며, 이를 위해 191명을 대상으로 설문조사를 실시하였다. 연구결과 인지된 유용성에 영향을 미치는 외생변인은 '친화성' '상대적 이점' '혁신성' 및 '몰입도' 이었으며, '접근성'은 유의미한 영향을 주지 못하는 요인으로 확인되었다. 또한 외생변인 중에서 '혁신성'이 UHD 방송에 대한 인지된 유용성에 가장 영향력이 있는 요인이었고, '상대적 이점', '몰입도' '친화성' 순으로 인지된 유용성에 영향을 주는 것으로 확인되었다. 특히, UHD 방송에 대한 인지된 용이성이 인지된 유용성에 영향을 미치는 중요한 요인이며, UHD 방송 시청태도와 시청의향에 영향을 미치는 것은 '인지된 유용성'이었고, '인지된 용이성'은 시청태도에 "시청태도"는 시청의향에 유의미한 영향을 주지 못하는 요인으로 확인되었다. 이러한 결과로 볼 때, UHD 방송에 대한 '인지된 유용성'은 UHD 방송 '시청태도'와 '시청의향'에 큰 영향을 주고 있음을 알 수 있다.

This study was conducted to examine the effects of interactivity, entertainment and ease of use, which are positive characteristics of SNS, on SNS using satisfaction and using reluctant intention and the roles of perceived values and trust among users in the relationships among these variables, in order to find a clue to contribution to positive use and development of SNS. For this study, a survey was performed targeting normal people in Seoul and the metropolitan area and a total of 224 effective questionnaires were acquired. Then frequency analysis, descriptive statistic analysis, correlation analysis and structural equation path analysis were carried out. As a result of analysis, interactivity and ease of use increased SNS using satisfaction and decreased using reluctant intention via trust and users' perceived values respectively. The result of analyzing the modification model showed that interactivity and entertainment directly increased SNS using satisfaction. These findings imply that SNS providers fully need to reflect the needs of consumers for interactivity, entertainment and ease of use for improving consumers' perceived values and trust. It is also concluded that consumers can enjoy positive SNS activities by increasing trust with SNS users through a positive understanding of interactivity and participation.
