Lack of trust is major reason for many company to take a cautions stance towards business-to-business electronic commerce. Especially innovative business models such as online business-to-business marketplaces face the lack of not only having to give their members and partners faith own capabilities and reliability, but also to ensure that the respective parties interacting through them have trust in each other. This paper is empirical study on the trust factors affecting the repurchase intentions in a B2B e-Marketplace by survey instrument based on Likert-style 5 point measurement scale. The objective of this paper is evaluation of relationship between repurchase intentions and trust. The focus of this paper is the antecedents and consequences of buyer trust in a B2B e-Marketplace, not trust intermediaries or in third parties that might mediate between the buyer and e-Marketplace. The findings of this study are expected to increase the awareness of B2B e-Commerce adopter and implementers about the importance of trust in e-commerce participation.

System usage, the utilization of information technology(IT) by individuals, groups or organizations, is a core variable in IS research. Indeed, there is widespread agreement among researchers that system usage is the primary variable through which IT affects white collar performance because it is a requisite, albeit insufficient, for deriving the benefits of IT. Furthermore, system usage has a notable practical value for managers interested in evaluating the impact of IT. Despite the number of studies of targeted at explaining system usage, there are more areas which required for the verification of system usage. The purpose of this paper is to address, using the Technological Acceptance Model (TAM), the usage pattern of AHP toward the various task in group decision (GD). The result showed that, for the all of the task types, perceived usage (PU) has more effect than perceived ease-of-use(PEU) on the AHP usage. However, more researches are required to generalize the result of this study.

Purpose - This study aims to provide a brief understanding of usability and its extended models with TAM as well as identifying additional determinants that had been suggested in previous studies on mobile services. Research design, data, and methodology - Empirical data were collected by conducting a field survey of potential mobile application service users. The call for participation was also made in mobile related application issues, which were widely discussed. Result - The ease of use and usefulness had a significantly positive influence on attitude and intention. It also was revealed that added value services can offer practical value to customers. Thus, positive attitudes toward the adoption of services by customers are present when they perceive higher usefulness and ease of use of mobile application services. Conclusion - It was indicated that customers who are more inclined to try new products or who have a higher demand for new things tend to think about those functionalities and added value mobile application services from the perspective of usefulness and ease of use and operation.

This study is intended to identify the factors affecting the successful information warehouse (IW) implementation through the technology acceptance model. As the IW has played an important role with the organizations, it has become a strategic management tool. However, because the building of an IWS requires a great amound of financing and a multi-period, managers should consider identifying the variables as a predictor of IWS success. The related research areas, such as TAM , TRA, and innovation diffusion theory, and previous research associated with the EWS success factors are reviewed in this paper. Based on the hypotheses presented , the study will empirically test the relationships between six external variable-user involvement, computer self-efficacy, OLAP characteristics, problem difficulty , user training and top management support-and system utilization via user's perceptions of ease of use, unusefulness. This study semmes to be a first attempt in this research area, and its results will provide general guidclines for IWS project managers to enhancement the like hood of system succes.

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.

After the launch of smart phones, various miniaturized smart devices such as wearable and IOT devices have deeply embedded in human life, and have created a technology-oriented society. In this technology-oriented society, technology development itself is important, however it seems more important to utilize existing technology appropriately and deliver effectively to human life. As the computer became personalized after the appearance of PC, human-centered computing such as HCI and UCD had begun to appear. However, most of the researches focused on technology that made human being convenient to interact with computer such as computer systems design and UX development. In the technology-oriented society, it seems more urgent to apply existing technology to human life. In this paper, we propose a methodology, 'Digital Leveraging' which guides how to effectively apply technology to human life. Digital Leveraging is the way of convergence between technology and humanities.

This study investigates the perception and adoption of ChatGPT (a large language model (LLM)-based chatbot created by OpenAI) among Korean users and assesses its potential as the next disruptive innovation. Drawing on previous literature, the study proposes perceived intelligence and perceived anthropomorphism as key differentiating factors of ChatGPT from earlier AI-based chatbots. Four individual motives (i.e., perceived usefulness, ease of use, enjoyment, and trust) and two societal motives (social influence and AI anxiety) were identified as antecedents of ChatGPT acceptance. A survey was conducted within two Korean online communities related to artificial intelligence, the findings of which confirm that ChatGPT is being used for both utilitarian and hedonic purposes, and that perceived usefulness and enjoyment positively impact the behavioral intention to adopt the chatbot. However, unlike prior expectations, perceived ease-of-use was not shown to exert significant influence on behavioral intention. Moreover, trust was not found to be a significant influencer to behavioral intention, and while social influence played a substantial role in adoption intention and perceived usefulness, AI anxiety did not show a significant effect. The study confirmed that perceived intelligence and perceived anthropomorphism are constructs that influence the individual factors that influence behavioral intention to adopt and highlights the need for future research to deconstruct and explore the factors that make ChatGPT "enjoyable" and "easy to use" and to better understand its potential as a disruptive technology. Service developers and LLM providers are advised to design user-centric applications, focus on user-friendliness, acknowledge that building trust takes time, and recognize the role of social influence in adoption.

본 연구는 의료기관에 블록체인 시스템을 도입하기 위하여 기술수용모델을 사용하였다. 그리고 외부변수는 선행연구를 통해 5가지(보안성, 가용성, 신뢰성, 다양성, 경제성)를 도출하였다. 그리고 지각된 용이성, 지각된 유용성이 정보신뢰를 통해 수용의도에 가는 경로로 연구모형을 설정하였다. 분석결과 H1의 경우 H1-1(보안성 →지각된 용이성)은 기각되었다. 그리고 이를 제외한 H1-2(가용성 →지각된 용이성), H1-3(신뢰성→지각된 용이성), H1-4(다양성 →지각된 용이성), H1-5(경제성 →지각된 용이성)는 채택되었다. H2는 블록체인 특성 5가지와 지각된 유용성과의 관계 가설로써 모두 채택되었다. H3과 H4를 살펴보면 H3-1인 지각된 용이성이 유용성으로 가는 경로가 유효하지 않았으나 H3-2(지각된 용의성 → 정보신뢰)와 H3-3(유용성 → 정보신뢰), 그리고 H4(정보신뢰→수용의도)는 모두 채택되었다. 본 연구에서는 의료기관에서 블록체인 기술이 도입되기 위해서는 안성을 강화시키는 것도 중요하지만 사용자측면에서 용이성을 높일 수 있는 설계가 필요하다는 것을 확인할 수 있었다.
