최근 스마트폰과 스마트패드 등 다양한 스마트기기가 보급됨에 따라 경제, 사회 등 각 분야에서 '스마트 혁명'이라는 혁신적인 변화가 발생하고 있다. 이러한 변화는 TV 분야에서도 일어나고 있는데 최근 출시되고 있는 스마트TV는 인터넷 접속, 애플리케이션 실행 등을 지원함으로써 이전의 TV와 차별화된 서비스를 제공하고 있다. 본 연구에서는 스마트TV의 수용에 영향을 주는 요인을 도출하고 그 요인들 간의 구조적인 관계를 밝히고자 한다. 새로운 기술이 추가된 스마트TV의 경우 기술수용모형을 확장하여 사회적 영향 같은 외부적인 환경의 요인과 혁신성과 같은 사용자의 특성을 반영한 모형을 수립하고 이들 간의 관계를 구조방정식 모형으로 분석하였다. 분석결과 개인의 혁신성과 사회적인 영향은 지각된 특성에 영향을 주어 스마트TV를 수용하는데 영향을 미치고 있는 것을 알 수 있었다. 또한 수립된 모형이 성별이나 스마트기기 경험 정도에 따라 차이를 보이는지 살펴보기 위해 조절효과를 추가로 분석하였다. 성별에 따른 차이는 없었으며 스마트기기 노출정도가 높은 집단은 혁신성이 지각된 유용성과 수용에 영향을 주는 반면 노출정도가 낮은 집단은 혁신성이 지각된 용이성과 유희성에 영향을 주어 최종적으로 스마트TV 수용에 영향을 주는 것을 알 수 있었다.

Technology Acceptance Model (TAM) considers perceived ease of use and perceived usefulness as the important determinants of user behavior regarding information technology. As an extension of TAM, this research examines perceived security as an additional determining variable to explain an individual's acceptance and use of mobile banking as well as internet banking. The results show that perceived ease of use does not affect the individual's attitude toward the use of mobile or internet banking, while perceived usefulness does. Furthermore, perceived security affects perceived usefulness in mobile banking, but not in internet banking. In addition, in mobile banking, perceived security is positively related to perceived usefulness, though perceived security is negatively related to attitude. Finally, the average scores of surveyed data for Internet banking are higher and significantly different than those for mobile banking.

Understanding user acceptance of the Internet, especially the intentions to use Internet commerce and mobile commerce, is important in explaining the fact that these commerce have been growing at an exponential rate in recent years. This paper studies factors of new technology to better understand and manage the electronic commerce activities. The theoretical model proposed in this paper is intended to clarify the factors as they are related to the Technology Acceptance Model. More specifically, the relationship among trust and other factors are hypothesized. Using the Technology Acceptance Model, this research reveals the importance of the hedonic factor. The result of this research implies that the ways of stimulating and facilitating customers' participation in mobile commerce should be differentiated from those in Internet commerce.

This study proposed an expanded technology acceptance model (TAM) incorporating perceived fee (PFE) and perceived enjoyment into the original TAM We examined that the extended TAM provides supplementary information about behavior intentions (BI) toward mobile data services (MDS). This study also investigated some significant differences in the relative influence of the determinants of BI toward MDS depending on experience. The extended TAM was empirically evaluated by using survey data collected from 149 inexperienced users and 393 experienced users. The findings indicated that PFE is the strongest determinant of BI toward MDS, and the antecedents leading to users' BI vary over time. The results may provide further insights into MDS practitioners and marketing managers.

Recently, with the proliferation of smart phones and mobile devices and the increase in the speed of mobile Internet, IT services are increasingly used in smart phones and mobile devices in a different way from the past. That is, a cloud service that downloads and uses data stored in the server in real time is expanding, and as a result, the security due to the continuous Internet connection of the user becomes a problem. In this study, we analyzed the relationship between factors affecting the continuous use of personal cloud service by using technology acceptance model. In addition to the technology acceptance model, confidentiality, privacy, accessibility, innovation, and self-efficacy were extracted from the existing research with emphasis on the characteristics of the cloud service and security factors. Moreover, the difference of intention to use among genders was verified through structural equation modeling with survey data from 262 personal cloud service users.

The primary objective of this paper is to examine of post acceptance behavior model in VCC services. Based on the relevant literature reviews, this study posits six characteristics, that is, expectation confirmation, perceived usefulness, perceived enjoyment, satisfaction, and continuance intention as key variables to describe the post acceptance behavior model in VCC services. And then we constructed a research model and hypotheses about relationship between these variables. A total 286 usable survey responses of CCC service users have been employed in the analysis. The empirical results of this study are summarized as follows. Firstly, expectation confirmation has a positive effect on the perceived usefulness, perceived enjoyment, and satisfaction. Secondly. perceived enjoyment has a positive effect on the satisfaction. Lastly, perceived usefulness, perceived enjoyment, and satisfaction have a positive effect on the continuance intention. These results will be helpful for the UCC services sector to further develop a service delivery strategies for strengthening the ongoing relationship with customers. Finally, some possible limits of the present research and future directions for such research were discussed.

Despite their potential value, the mobile Internet services in the domestic market have not been widely accepted as industry experts have expected. To understand why, this study uses the TAM, Technology Acceptance Model, and explores the factors affecting the usage behavior of the end-users. Based on statistical analysis of survey data, we show that social influence and perceived ease of use affect perceived usefulness, and that self-efficacy and focus significantly influence perceived ease of use. Furthermore, perceived usefulness is shown to play a significant role in explaining actual usage of the mobile Internet services. However, contrary to the hypothesized relationships, service quality, focus, and innovativeness of users turn out to have little impact on the traditional endogenous TAM variables such as perceived usefulness, perceived ease of use, and actual usage behavior. Based on these results, we attempt to provide managerial implications for the domestic mobile Internet service providers and to suggest future research directions in this domain of research.

The purpose of this study is to investigate as individuals how and why to accept web storage service. Using the Technology Adoption Model2 (TAM2) as methodological framework, this research tries to experiment an empirical background on the acceptance of behavioral changes of an individual sa to information technological advances. The findings of this study are different from TAM2 in terms of job relevance and output quality. However, according to other elements of TAM2 such as result demonstrability, subjective norm, image, this srudy also confirms positive relationships toward technological acceptance. Especially, subjective norms shows the strongest influential factors when adopting technological changes.

Internet has begun various transformation and innovation in terms of society, culture and industry. Today, Social Network Service(SNS) is an exceedingly popular and useful tool for making human relationships. Previous studies related to SNS, which based on Technology Acceptance Model(TAM), were focused on user acceptance of new technology. However, they had the limitations to focus on technology acceptance, without the consideration of the cognitive factors in using SNS. This study examined how the main factors of intention to use of SNS continuously affect perceived usefulness and ease of use through familiarity, self-expression, hedonic shopping value, utilitarian shopping value and personal relationship. The results of hypothesis testing showed that familiarity, self-expression, hedonic shopping value and personal relationship have some positive impacts on the perceived usefulness and ease of use. The practical contribution of this study is to suggest useful decision alternatives concerned to marketing strategies for acquiring and retaining long-term customers related to SNS business.

기술발전에 따른 혁신제품 및 서비스에 대한 연구는 유용성과 편의성을 중심으로 그 수용 및 저항을 서로 다른 관점에서 보아왔다. 그러나 소비자 혹은 사용자들이 느끼는 혁신제품 및 서비스에 대한 태도와 평가는 수용하려는 측면과 저항하려는 측면이 동시에 작용하며 그 결과로서 사용의도 혹은 구매의도가 결정된다고 볼 수 있다. 이에 본 연구는 혁신제품 혹은 서비스가 갖는 다양한 속성을 기술수용모형(TAM: Technology Acceptance Model) 에서의 지각된 유용성(Perceived Usefulness) 과 지각된 편의성 (Perceived Ease of Use) 개념을 사용자 지각에 기초하여 상대적 이점, 유용성, 편의성, 기술혁신성, 사용법의 변화 인식, 위험지각 등으로 구체화하고 각각의 개념이 수용적 태도와 저항에 미치는 영향을 분석하였다. 아울러 수용적 태도와 저항이 사용의도에 미치는 영향력을 동시에 분석 및 비교하였다. 연구에서 얻어진 결과를 중심으로 혁신제품에 대한 소비자 중심의 관리적 시사점도 제시하였다.
