This study analyzed the diffusion process of digital convergence products focused on camera phon to compare the traditional adoption-diffusion model with use-diffusion model proposed by Shih and Venkatesh(2004). The results suggested that observability, perceived usefulness, innovativeness, relative advantage have effects on the intention of repurchase in the adoption-diffusion model. On the other hand, the intention of repurchase has been affected by technological sophistication, satisfaction, innovativeness, relative advantage in the use-diffusion model. These results imply that the traditional adoption-diffusion model could be applied to the cases of the digital convergence products. In addition, the results also show that the use-diffusion model is superior to the traditional model in analyzing the diffusion of digital convergence products.

The purpose of this study is to identify what elements of VR games satisfy and continuous usage for the sustainable development of VR games. Specifically, an extended acceptance model was proposed with the addition of perceived costs, presences, satisfied variables to predict the acceptance and the intention of continued use of VR games. As a result, in general, it was found that the extended technology acceptance model with three external factors is more advantageous to explain the characteristics of VR game and its effect on users than the existing model. This study is suggested an integrated research model that considers the core characteristics of VR games and observe which factors lead to the persistent intention to contribute to the study about the VR game.

최근, 맞춤의료서비스, 헬스와 웰빙의 복합서비스, RFID 기반의 공급망 관리 서비스와 같이 정보기술(IT), 바이오기술(BT), 나노기술(NT) 등이 융합된 혁신적인 서비스들이 출현하고 있다. 그러나 기존의 전통적인 접근방법으로는 새로이 출현하는 다양한 서비스에 대한 체계적인 접근이 불가능하다. 따라서 분석의 단위를 조직이나 정보 시스템 수준에서 서비스 수준으로 하향하는 것과 요소기술이 서비스로 변환되어 소비자에게 수용되는 전체과정을 동태적, 공학적으로 설계하는 접근이 절실히 요구된다. 본 연구의 목적은 신 기술의 출현, 성숙, 시장으로의 유입과 소비자에 수용되는 서비스 생명주기 전 과정을 통태적 관점에서 분석하는 틀을 제시하고 의료서비스에 특화 하여 서비스 공학적 관점에서 IT, BT, NT가 융합된 서비스를 설계하는 모델을 제시하는 것이다. 이를 위해 우선 서비스의 특성과 서비스 시스템 설계의 목표를 제시하고 동태적 혁신이론에 기반하여 서비스의 탄생부터 시장에서의 수용에 이르는 생명주기를 표현할 수 있는 모델을 개발한다. 이 모델의 시간 축을 분기하여 단계(Stage)들을 도출하고 각 단계에서 수행해야 할 활동들을 설계한다. 아울러 모델의 실제적 유용성을 입증하기 위하여 의료분야의 관련사례를 제시하고 조직의 서비스전략과 다변화 전략을 수립하기 위한 논리도 제시하였다. 본 연구의 동태적 공학모델은 IT 생태계 (IT Ecosystem) 하에서 조직 및 IT 요소들이 다양한 환경에서 어떻게 안정적이고 효율적인 메커니즘을 형성하고 진화해야 하는지를 잘 보여주고 있다.

The purpose of this study is to empirically analyze the moderating effect of psychological empowerment on the relationship between technostress, the technology acceptance model, and the continuance intention of use. The results of the analyses are as follows: First, IT corporation workers' technostress had a negative effect on perceived ease of use and perceived usefulness. Second, psychological empowerment was found to regulate the relationship between technostress and the technology acceptance model. Third, the perceived ease of use of IT corporation workers had a significant positive effect on the continuance intention of use, and the perceived usefulness had a positive effect on the continuance intention of use. These findings imply that training and education should be continuously conducted to improve psychological empowerment as well as manage technostress.

Augmented reality (AR) or virtual reality is suitable to apply the contents of a textbook so as to be directly observable by learners. This study aimed to examine the applicability and technology acceptance of anatomy learning using AR in nursing students. This study was conducted in May 2019 with 17 nursing students who studied an anatomy textbook using AR and answered a questionnaire about technology acceptance and the usability of AR in combination with the anatomy textbook. Perceived usefulness was identified as an influencing factor on technology acceptance with 51.2% acceptance rate and thus should be taken into consideration in the development of learning strategies using new technological learning methods.

In this study, the Technology Acceptance Model (TAM) was applied to explore the process of using card news. Card news users are found to be active in searching and selecting appropriate news for themselves, information seeking style and news literacy were established as antecedent variables that can influence card news usage. A survey of 400 university students with experience of using card news was conducted. For statistical analysis, SEM was conducted. The analysis showed that information seeking style significantly affects perceived ease of use (PEU) and that news literacy influences neither PEU nor PU. PEU was found to have a significant effect on PU, and both PEU and PU had a significant effect on recommendation intention.

유비쿼터스 환경 하에서 새로운 첨단 핵심기술 및 서비스가 하나의 제품 안에 집중되어가는 시대적 요구가 대두되고 있다. 이에 부응하여 탄생한 컨버전스 제품인 텔레매틱스의 전망 역시 두드러지고 있다. 본 연구는 Davis[14]가 제안한 기술수용모델(Technology Acceptance Model:TAM)을 통하여 텔레매틱스 사용의도에 관한 수용모형을 제시하였다. 기술수용모델의 내부 요인인 사용의도, 인지된 유용성과 인지된 이용용이성 외에도 업체 신뢰도, 정황 인식성, 자기 효능감의 외부 요인으로 확장하여 요인 간의 구조적 관계를 위한 모형을 개발하였다. 실증분석을 한 결과 정황 인식성, 자기 효능감이 각각 인지된 유용성과 이용용이성에 영향을 미치는 것으로 나타났다. 이러한 결과를 토대로 텔레매틱스의 이용자에게 중요시 되는 특성에 대해 논의하였다.

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.

This study analyzed the factors that influence the domestic SMEs that have introduced smart factories on their intention to accept at a higher level for qualitative advancement. 375 copies collected through an online survey were analyzed using SPSS and AMOS with UTAUT and the extended two-stage information system continuous model. Performance expectancy, effort expectancy, social influence, and facilitating conditions have a statistically significant effect on user satisfaction and user satisfaction and CEO's will have an effect on the intention to accept the advancement. However, the suppliers' technology didn't have a direct effect on the advancement acceptance intention and user satisfaction has a mediating effect between performance expectancy, effort expectancy, social influence, facilitating conditions and the advancement acceptance intention. SME's advancement for smart factory, it is important to improve the satisfaction level and the CEO's will to become smart.
