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.

This study is to investigate into the factors that influence the use of a military logistics information system in Korean army. We developed the research model based on DTPB (Decomposed Theory of Planned Behavior) because the DTBP is an appropriate model in a mandatary using environment through the study of previous technology-acceptance models. A questionnaire survey was conducted with Korean army solders and civilian components who use the army logistics information system and 266 valid questionnaires are recovered. The collected data were analyzed by SPSS and AMOS. The results show that perceived usefulness and ease of use did not affect the attitude of the use intention. The influence of colleagues and upper class officers was all satisfactory and computer self-efficiency affected perceived control of behavior. The results of this study will contribute to the further use of the military logistics information system and future development strategy.

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 understand students' use intentions of Web Based Collaborative Learning (WBCL) system. To meet this purpose, we developed a research model based on the Decomposed TPB. This model contains 5 influencing factors: Explicit social influence(EXSI) and Implicit social influence(IMSI), Perceived Usefulness (PU), Perceived easy of use(PEOU), Perceived Playfulness(PP). Data was collected 254 university students from two different institutions. Also, the analysis is conducted to do the hypothesis testing by using PLS 3.0. The result shows that influence factors except PEOU have a important and significant impact on user Behavior Intention(BI). Using WBCL system and learning tool, team leader(that is referent) and members can be a good interaction. For these same reasons, We found that especialy Explicit social influence(EXSI) and Implicit social influence(IMSI) are special influence factors in reference group.
