As smart devices have proliferated and network speed and accessibility of mobile have accelerated, mobile cloud services that can do the same tasks by various devices are promoted. This paper explores the analysis of use intention of mobile cloud services and influencing factors. We develop and apply a convergence technology acceptance model which combines TAM, VAM and UTAUT. The proposed model verifies some hypotheses to aware the significant factors of use intention of mobile cloud services with TAM, VAM and UTAUT including additional mobile cloud service characteristics such as mobility, high availability, easy accessibility and scalability. Eventually, this research can not only help users gain insights into mobile cloud service use intention, but also help mobile cloud service providers to develop more effective mobile cloud service and their business strategy in the future.

As systematic information protection and management is recognized as an organization's core value, organizations are pursuing a shift from an individual-centered information management method to an organization-oriented information management method. The Enterprise content management system(ECMS) is a solution that supports document security and information sharing by insiders and is being introduced by many organizations due to recent technological developments. The purpose of this study is to present a method of improving performance through continuous use of the ECMS from the user's point of view and also suggest a method to improve the intention of continuous use through the expansion of the technology acceptance model. This study surveyed the employees of organizations that adopted the ECMS and verified the research hypothesis derived from previous studies through structural equation modeling. As a result of the analysis, usefulness, and ease of use affected on the intention of continuous use of the ECMS, and the knowledge sharing culture and the ECMS quality factors affected the technology acceptance model factors. The results of this study have academic and practical significance in terms of suggesting a plan to increase the usability of the ECMS from the user's point of view.

By conceptualizing UCC users' active behavior, this study newly presents two key concepts, 'self-expression' and 'artistic activity' of UCC users. Then, this study suggests a research framework to analyze text, image, and video UCC adoption processes by integrating those concepts with already-built UCC research tradition. Using the framework, we found that individuals who has a hard time expressing themselves in reality are likely to have a favorable attitude toward UCC, and the stronger the faith about the justice of self-expression and its freedom, the more the favorable attitude toward UCC. Furthermore, we confirmed that individuals who are very interested in artistic activity, and individuals who has high self-efficacy to their artistic talent are likely to participates more in UCC production. The role of other factors such as perceived enjoyment, the perception of critical mass of UCC adoption, and subjective norm also were discussed with limitations of this study.

This paper aims to explore the question of whether the environment in Korea where credit card use is prevalent affects the intention to accept Fintech-based mobile payment. The institution that encourages the credit card use such as credit card receipt obligation may lead to the lock-in and build infrastructures to influence the acceptance of new payment acceptance. This paper investigates how the perceived of use, usefulness, accessibility and stability affect the intention to use mobile payment based on the Technology Acceptance Model(TAM) model with the mediator of lock-in and moderator of credit card receipt obligation. In the results, we found that the perceived usefulness, perceived ease of use and accessibility positively impact on the intention of mobile payment usages. It is also observed that the usefulness and accessibility of credit cards positively mediate to the intention of mobile payment use.

IPTV has been drawing attention as a representative convergence media. The analysis of the convergence media, as like IPTV, requires an investigation into the use perception and multidimensional factors. So this research examines the IPTV usage, based on the Technology Acceptance Model. The analysis was made with the 500 users, based on the online survey. The first results is concerned with the user characteristics. A positive influential relationship between the user characteristics and use perception was confirmed, along with the individual attribute and environmental influence. The second, 'perceived ease of use' was found to positively influence 'perceived usefulness' and 'perceived playfulness'. This finding suggests that it is an important diffusion strategy to enhance the ease of use of IPTV. The third is the emphasis of playfulness of IPTV. Since IPTV is multimedia, playfulness played a significant role in diffusing IPTV. The application of the TAM to the media analysis of IPTV, which reflects the environments of the convergence media and use perception, was successful in drawing a significant outcome.

Despite recent changes in life style, the content called bookstore has steadily stood by our side, changing its shape. In this environment, This manuscript is a quantitatively empirical study that individual innovation affects a combined bookstore's service design factors and the user's intention to word of mouth. Researchers believed that individual innovation would affect a combined bookstore's service design factors. It was also assumed that there would be considerable causality between the combined bookstore's service design factors deduced through prior study. Furthermore, the assumption that these parameters would affect internal variables, perceived ease of use, perceived usefulness and satisfaction, word of mouth intentions was presented, and verified using An Integrated Model of Extended Technology Acceptance Model and Post Acceptance Model. Researchers expect that this research will contribute significantly in that it is a developer's approach to the combined bookstore that are seen as major tenants in large retail facilities.

지리정보 분야에서 다양한 지리정보를 공유 및 교환, 전송하기 위해서는 데이터 스트리밍 관점에서의 일관성과 무결성을 유지 할 수 있는 지리정보 모델이 필요하다. OpenGIS Consortium, Inc.(OGC)에서 제안한 국내외 지리정보 엔코딩 표준 방식인 Geography Markup Language(GML)은 상호운영을 전제로 이러한 목적에 부합되는 모델이다. 본 연구에서는 한국정보통신기술협회(TTA)에서 공표한 우리나라 표준 교통데이터 모델인 TTA 교통모델을 기반으로 하여 이 데이터 모델을 수용하는 GML 응용 시스템을 설계 및 구현하였다. 또한 OGC 그리드 커버리지의 관점에서 영상 정보의 활용이 증가함에 따라 영상 정보의 엔코딩 과정을 부가하여 시스템의 확장 가능성을 검토하고자 하였다.

본 연구는 승객이 국내 공항에서 셀프 체크인 kiosk를 사용하려는 행동 의도에 관해, 개인적 특성과 상황적 변수의 조절효과를 실증 분석하는 데 목적을 두고 있다. 공항 Kiosk를 사용함으로써 승객과 항공사, 공항은 비용 절감의 이점을 누릴 수 있다. 그에 따라 항공사와 공항 측에서는 이러한 경제적 효용을 보다 많은 사람들이 누릴 수 있도록 하기 위해 kiosk의 보급을 늘이고자 하는 입장이다. 그럼에도 불구하고 공항kiosk의 사용률은 아직까지 낮은 수준에 그치고 있으며 그에 관한 연구도 활발히 이루어지지 않고 있다. 이에 본 연구에서는 확장된 기술수용모델을 기반으로 하여 개인적 특성과 상황적 변수가 승객의 kiosk 사용의도에 미치는 차별적 영향에 관해 분석하고자 한다.

This paper proposes perceived ease of use and perceived usefulness mediate this relationship. The results can be summarized as follows. First, the greater the property management system's information quality, the greater the perceived ease of use. Second, the greater the perceived ease of use, tile greater the perceived usefulness. Third, the greater the perceived ease of use, the greater the using intention of system. Forth, the greater the perceived usefulness, the greater the using intention of system. Finally, the greater the using intention of system, the greater the usage of system.

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.
