Given the increasing of adoption of use of Mobile Wireless Technology(MWT), this study aims at investigating the key influencing determinants of individuals' MWT adoption and use. Based on the Technology Acceptance Model(TAM), the research model proposed new constructs and casual relations, Perceived Safety(PS), Perceived Costs(PC), Company's Willingness to Fund(CWF), and Experience(E) as a moderator. The model was tested using Structural Equation Modeling(SEM) using AMOS 5.0 analysis on the sample collected from 387 MBA and Executive MBA students of several domestic and foreign universities. The results show that not only the variables, except Perceived Usefulness, in the original TAM model, but also new variables in the research model had a significant influence on other variables. The implications of the findings suggest a new theoretical framework for future IS/IT research and offers suggestions that the developers of MWT should consider regarding the technology

본 연구는 Virtual Space의 수용에 어떻게 영향을 미치는지를 파악하고자 하는 연구이다. 이 연구는 정보기술수용 모형의 확장모형인 TAM2(Venkatesh & Davis, 2000)를 적용하여 연구하였으며, 실제 Virtual Space를 사용한 경험이 있는 사용자를 대상으로 설문하여 SPSS와 AMOS를 이용하여 TAM2 모형을 검증하고자 하였다. 연구결과 정보기술 수용에 대한 대상이 조직 내부의 이용자로 연구했던 TAM2와 다르게 외부변수 중 직무관련성과 결과 품질에 대한 변수가 유의하지 않은 것으로 나타났다. 하지만 주관적 규범, 이미지, 결과 논증가능성 등은 유용성에 정의 영향을 주었으며, 특히 외부 변수 중 주관적 규범은 매우 큰 영향을 주고 있는 것으로 나타나 새로운 정보기술의 수용에 있어 중요한 요인으로 분석되었다. 본 연구 결과의 시사점과 한계점 및 향후 연구방향을 결론에서 제시하였다.

New technology had been introduced continually and in many cases, we approached technology persepectives when the new technology were introduced. It was very important that researching users acceptance of the new technology in the areas of marketing and strategy. Regarding to user accepatance of new technology, many research models had been exited. This study compared with 2 models which were proposed by Venkatesh et al. named UTAUT1, UTAUT2 based on the criteria which composed of application context, variables of model, the impacts of variables. The dominant matric which was applied in all functions and industries was not exited. For the purpose of improving predictability, single or compound matrics were useful according to industries and usage

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.

This study is focused on analyzing the difference by demographical characteristics of users on acceptance behavior of tourism omnichannel based upon Unified Theory of Acceptance and Use of Technology. Through field survey with 392 respondents, the results are as follows. Partially differences on acceptance behavior are found according to gender, age, education and job as demographic characteristics of tourism omnichannel. And the difference by demographic characteristics on acceptance behavior about preferring tourism information is not significant. However performance expectancy and effort expectancy as factors of UTAUT are significantly positive in thirties group of tourism omnichannel users.

This study was conducted to identify factors that influenced teachers' adoption of digital textbooks and causal relationships among the factors identified. Chasm theory was used in developing strategies for adoption of digital textbooks that consider teachers' innovativeness. This study also employed the information technology adoption model of Davis (1989) that illustrates decision making processes for the adoption of instructional media such as digital textbooks. Based on these two theories, a measurement instrument measuring teachers' innovativeness, perceived usefulness, perceived ease of use, and intention of use was developed and validated through a series of reliability and validity tests. Causal relationships among the factors were examined using structural equation modeling. The result indicated that: a) perceived ease of use had a directional effect on perceived usefulness and an indirect effect on intention of use; and b) perceived usefulness had a direct effect on intention of use. Implications of this finding are discussed especially for the efforts in developing strategies for teachers' adoption of digital textbook. For example, when digital textbooks are introduced into public schools, teachers' perception of the usefulness of digital textbooks, beyond just ease of use, should be considered.

This study aims at providing the basis for improving the applicability of ERP system in those companies which plan to introduce it or those which already introduced, but were not able to achieve the intended effect. To this end, this study focused on the empirical study to find innovation acceptance factors effecting innovation diffusion of ERP system intensively and to search the best path of innovation diffusion. Thus, it was known that innovation characteristics factors, percieved ease of use, perceived usefulnessand implementation of ERP system affected innovation diffusion directly or indirectly and there was a significant path helping companies introduce information system successfully.

The aim of this study was to search for the effects of health self-efficacy and technology self-efficacy on user's behavioural intention by the extended TAM focused on smartphone base ubiquitous health system. In this research, in view of small sample size, PLS - SEM methodology was applied to this study in order to the proposed research model. As a result of analysis, the statistical fitness of proposed research model was confirmed through GoF value and the path coefficient was calculated for the hypotheses test. Finally, the implications of analysis result showed that when the use of smartphone device could be easily accessed in the side of technology self-efficacy, the possibility of user's behavioural intention also might be higher.

This study explored an appropriate research model that could explain and predict the spread of fintech, a new financial services in Korea. We reviewed two theoretical frameworks, theory of planned behavior(TPB) and technology acceptance model(TAM), which are frequently cited to explain human behavior and new technology adoption, respectively. Then, we proposed a decomposed theory of planned behavior(DTPB) as a research model and examined the model through PLS path modeling. As a result, every path except PEOU-ATT path in TAM is significant, and the explanatory power toward behavioral intention(R2=0.573) is also significantly greater in the proposed model. Accordingly, the proposed DTPB is appropriate to explain the spread of fintech in Korea. Finally, suggestions for the following studies are discussed.
