This study proposed a research model that can explain the usage intentions of users and non-users by considering the performance aspects of personal mobility and external environmental factors based on the SOR (Stimulus-Organism-Response) model, A survey was conducted targeting domestic users and non-users, and research models and hypotheses were verified through Partial Least Square (PLS) and Artificial Neural Network (ANN). As a result of the analysis, it was confirmed that the users' perceived satisfaction and perceived trust had a positive effect on their intention to use, and that perceived risk and environmental value had a significant relationship with perceived satisfaction and perceived trust. For non-users, it was found that there was a positive correlation between perceived satisfaction and intention to use, and it was verified that perceived risk and environmental value, like users, were significant antecedents of perceived satisfaction and perceived trust. Among the remaining variables, the perceived mobility of users and the perceived ease of use of non-users were respectively presented as important influencing factors on perceived satisfaction.

This study intended to examine how customers of self-service technology of airlines perceive and adopt the technology, and how such perceptions affect their willingness to use it. The findings of analysis are as follows. First of all, self-efficacy, a personal characteristics variable, has significant effects on both perceived usefulness and ease of use (H1). Second, though personal innovation which accepts new information technology more positively and challenge to use it before others has significant effect on perceived usefulness (H 2-1), it does not have significant effect on ease of use (H 2-2). Third, perceived ease of use has effect on perceived usefulness. Forth, both perceived usefulness and ease of use have positive effects on willingness to use.

The wearables market has fast grown, demanding a more consumer-centric academic attention. The current research explores the moderations of consumer individual characteristics (i.e., age, need for cognition, involvement) in the dynamics of perceived psychological benefits of wearables adoption (i.e., perceived usefulness, perceived ease of use) towards perceived product quality. the results indicate a strong positive influence of both the perceived usefulness and ease of use on perceived quality. however, the predicted moderations of age, need for congitiion, and involvement were partially supported.

In this paper we investigate the factors influencing the purchase intention of Smart-Phone which was introduced recently. Smart-Phone is a new information technology that converges PDA into a mobile phone. It has a various functions such as phone, information processing, Internet search etc. New information technology like Smart-Phone gives us a very important and interesting research issue, which is to find and prove the factors influencing the purchase intention. We try to find and prove the factors influencing the purchase intention of Smart-Phone by expanding Technology Acceptance Model. We include the perceived playfulness to the research model in order to analyze the factors. This empirical paper proves that the perceived usefulness, the perceived ease-of-use, and the perceived playfulness give positive effects to the purchase intention. In addition, this paper indicates some managerial implications that various and useful applications and the easy user interface can help to increase the degree of user acceptance.

This study investigates the causal relationships among the factors influencing behavioral intention related to beef traceability and TAM to make diet safer. To do this, this study conducted a survey targeting the customers who use the department stores, specialty shops and large supermarkets in Seoul. The result is as follows. First, the higher the information quality in beef traceability(t=3.872) and social impact (t=1.938) were, the higher the usability became significantly. Second, as the social impact of food traceability(t=2.014), information accessibility(t=2.016), perceived risk(t=1.910) became higher, the perceived usefulness was shown significantly higher. Third, as the usability(t=5.826) was perceived higher, the perceived usefulness became higher. Fourth, the higher the perceived usefulness(t=4.264), the higher the behavioral intention among the customers. Also, the lower the usability(t=-0.682), the lower the behavioral intention.

본 연구는 정보기술의 사용(Usage)과 수용(Adoption)을 예상하는 목적보다는 웹 기반 협동합습 시스템사용 의도와 사용행위에 영향을 미치는 변수들을 폭 넓게 이해하고, 실질적으로 활용 할 수 있는 변수를 찾는데 목적이 있기 때문에 분해된 계획 행동 이론(Decomposed TPB)을 기반 하였고, 분해된 변수들 중 일부분(지각된 유용성, 지각된 용이성, 명시적 영향, 암시적 영향)과 웹 환경의 중요 요소인 '흥미성' 을 포함하여 사용의도(Use Intention)에 영향을 미치는 변수들을 2개 대학의 대학생 256명을 대상으로 자료를 수집하여 실증 분석하였다. 연구결과 다차원으로 분해된 일부 변수들 중 태도적 믿음 변수인 '지각된 용이성'을 제외하고 분해된 모든 변수가 사용의도에 긍정적 강한 영향을 미치고 있음을 알 수 있었고, 특히 주관적 규범(명시적 영향, 암시적 영향)변수는 준거집단을 통해서 웹기반 협동학습 시스템에 대한 행동의도나 인지에 영향을 줄 수 있는 중요 변수로 나타났다. 이러한 결과는 준거인이 되는 팀장은 팀원 및 학습자들과의 상호작용(협동학습을 통한 화상토론, 게시판정활동, 오프라인 정기 모임, 동영상 동시 시청)과 팀원 관리 및 운영하는 역할이기 때문에 새로운 정보 기술 및 시스템 사용 권유를 하거나, 직접 기술사용을 하는 주변 분위기는 협동합습에 참여한 학습자들에게 조금이나마 영향을 줄 수 있음을 추측 해 볼 수 있고 영향력 있는 중요변수임을 제시하였다.

The purpose of this study is to investigate the factors that affect the perceived awareness and the intention of continuous use by FinTech users and system characteristics. Data collection was carried out by targeting and surveying 600 people living in Gwangju, and office workers using smartphones. As a result, first, self-efficacy, innovation, and fitness for Fin-Tech services were found to influence the degree of perceptual awareness and intent to use of Fin-tech service users. Second, the system characteristics have a positive effect on perceived awareness and intention of using FinTech service. Third, the hypothesis about the dangers in the user attributes and system properties were dismissed. It seems that the priority concern was regarding the leakage of personal information and security as privacy and the increasing damage cases of financial fraud by electronic financial transactions spill. Therefore, in order to spread FinTech services, it would be effective if a Fin-Tech service strategy could eliminate inconveniences such as the risk of hindering convenience and intention to use by the marketing strategy established by the company.

The present study sought to shed light on specific designs and strategies by investigating the impact that team project-based learning approach using Naver Band had on learning outcomes specifically, on satisfaction and achievement. Variables of perceived usefulness and perceived ease of use were chosen as critical predictors of the learning outcomes. 70 undergraduate students were divided into 18 groups and instructed to work on a team project using Naver Band for 6 weeks. Data analysis was completed using descriptive statistic analysis, correlation analysis, hierarchical regression analysis. Also, descriptions of Band from team reflection journal were analyzed. The major results of the study are as follows: first, perceived usefulness was the significant predictor of satisfaction and achievement. Second, 5 functions were revealed as strengths about Band.

The purpose of this study is to investigate the predictability of variables among technology easy to use, perceived usefulness, and technostress that had impacts on kindergarten preservice teachers' technology intention to use. For this study, the survey data collected by 64 students who were enrolled in the kindergarten preservice teacher education were analysed by using multiple regression analysis. The results of this study showed as follows. First, technology easy to use significantly affected perceived usefulness. Second, technology easy to use negatively affected technostress. Third, perceived usefulness significantly affected technology intention to use while technostress negatively affected it. From this results, it is revealed that various technology training opportunities would be provided for improving preservice teachers' technology intention to use and lessing preservice teachers' technostress. Furthermore, effective teaching-learning strategies for utilizing technology as an educational media should be developed in the early childhood educational environment.

웹이 대중화 되면서 웹 사이트 개발의 초점이 개발자가 아닌 이를 사용하고 평가하게 될 사용자에게 맞춰지게 되고, 그에 따라 사용자가 쉽게 배우고 빨리 인식 할 수 있도록 개발하는 유저빌리티의 원리가 웹의 사용성을 향상시키는 데 있어서 중요한 역할을 하게 되었다. 본 연구는 웹 유저빌리티 요인인 컨텐츠, 디자인, 네비게이션, 상호작용성이 TAM의 지각된 유용성과 지각된 이용용이성을 매개로 고객 재방문 의도에 미치는 영향력을 검증함으로써 TAM을 확장하였다. 이 모형은 인터넷 서점을 방문한 경험이 있는 180명의 설문으로 LISREL분석이 사용되었다. 결과는 디자인을 제외한 컨텐츠, 네비게이션, 상호작용은 웹유저빌리티의 중요한 변수로써 지각된 이용용이성과 기각된 유용성을 매개로 재방문 의도에 영향을 맞는 것으로 밝혀졌다.
