  • The purpose of the research is to identify antecedents of mobile wallet continuance intention in Vietnam. A self-administered questionnaire was distributed to collect data from a total of 276 respondents. Partial least squares structural equation modeling was employed for analyzing the data. Five mobile wallet features - mobile application quality, mobile wallet familiarity, situational normality, payment security, and feedback mechanism - are introduced as fundamental elements, which influence customer' continuance intention to use mobile wallet in Vietnam. The results indicate that mobile quality application and familiarity can significantly influence perceived ease-of-use (PEOU) and perceived usefulness (PU), but situational normality has an impact only on PEOU. PEOU and PU are positively related to satisfaction. On the other hand, payment security and feedback mechanism affect positively customer' trust. As a result, the positive effects that satisfaction and trust have on electronic wallet continuance intention are confirmed. The findings can be used to advise mobile wallet providers to improve their platform design and services to retain users. As a theoretical contribution, this study combines the Technology Acceptance Model, Unified Theory of Acceptance and Use of Technology to investigate the key determinants on continuance intention in the context of electronic wallet in Vietnam.

  • Social Network Service (SNS) with emergence of Web 2.0 have been developed rapidly. Unlike other games, social network game is based on the relationship with smart devices and studied for user-centered behavior as a potential factor derived from the Technical Acceptance Model (TAM). This research is conducted for finding out influencing factors on continuous intention for smart device users. Therefore, the independent variables consist of subjective norm, mobility, playfulness, self-efficacy, and ease of use. The intermediate variables also compose of flow, and user satisfaction and the dependent variables as continuous intention.

  • 오늘날 비즈니스의 가장 중요한 요소 중의 하나는 타이밍이며, 이의 예측 정확성이나 대응력에 따라 비즈니스의 성패 정도가 달라질 수 있다. 이러한 의사결정력을 강화하기 위해서 많은 기업에서는 글로벌 선도시장의 흐름이나 선진기업의 성공전략에 대한 벤치마킹을 수행한다. 모바일 산업에 관한 한 한국은 글로벌 선도시장으로, 한국의 휴대폰 시장 변천을 분석하고 구매요인 및 요인간 관계를 규명하여 지표화할 수 있으면 여타 국가에서 시장주도 전략에 중요한 역할을 수행할 수 있을 것으로 예상된다. 따라서 테크놀로지 수용에 대한 기존 문헌연구를 바탕으로 끊임없이 변화하는 정보기술 제품이나 서비스의 수용 여부 및 시장 성장 예측에 대한 프레임워크를 개발 제시하는 것이 본 연구의 기본 목적이다. 개인차원의 기술 수용 모형인 Technology Acceptance Model(TAM) 및 여러 수정모형에서 규명된 다양한 변수들은 실증적인 연구의 결과로서 중요성은 갖으나, 여전히 연구 및 실무 관점에서는 특정 상황에 대한 통계 분석 결과의 제시라는 점에서 한계를 갖는다. 비교 대상국으로 선택한 중국은 그 국토만큼, 인구만큼, 문화만큼 다양하고 복합적인 시장이며, 동시에 누구나 공감하는 거대한 잠재시장이므로, 한국시장의 분석을 바탕으로 중국시장에 대한 향후 성장을 지표로 예측할 수 있다면 국내 기술 및 상품 수출의 기회를 보다 더 수익성있게 포착할 수 있을 것이라고 판단했기 때문이다. 그러나 여기서는 연구의 의의, 대표적인 일부 변수의 평가와 연구방법에 대한 제안에 국한하여 설명한다.

  • Global interests in RFID are increased and Korean government and companies make an active effort to propagate and spread RFID. Due to the overwhelming advantages of RFID system in comparison with existing bar code system, ripple effects on logistics sector among the utilizing fields of RFID technology are expected to be great, but application of RFID system is lowly progressed unlike the expectation of several experts. Therefore, this research extracts precedent studies on theoretical background, applying fields, promotion condition and domestic/foreign parts of RFID system, factors for operating domestic RFID system and effects and considers the effects of RFID's external variables on easiness and effectiveness of TAM. It confirms the relations of RFID applying effects for companies applying and utilizing RFID and verifies the relations among the effects for application of RFID system, accepting intention of RFID system and applying effects. Based on the results of analysis, it should play a role of good guide for all of companies and institution who will introduce RFID system to all of Korean logistics fields, make policies and systems which promote RFID acceptance nationally and socially and play a role of guide making confident climate for RFID technolog
