The business in the Ubiquitous era has to be developed by combing a traditional marketing concept with a new concept system on Chip. The objective of this paper is researching on the attention or interest, understanding, positive effects, etc., for Ubiquitous Computing to realize u-Korea and u-Business. The paper result which is the stepwise developing scheme of u-Business could be useful in the policy, publicity and education, strategic implementation of the Ubiquitous Computing. And the proposed new services for u-Commerce can be applied to new business model of future IT industry. Actually, the awareness and understanding about Ubiquitous are low, But, We can't overemphasize the value of Ubiquitous. First of all, The publicity and education about It's may have to be emphasized.

유비쿼터스 어플리케이션에서 컨텍스트 기반 정보 서비스의 필요성이 증가하고 있다. 이러한 어플리케이션 중 최근 활발히 논의되고 있는 유비쿼터스 커머스에서는 소비자의 다양한 컨텍스트에 따라 구매에 도움이 될 상품을 제공하는 정보 서비스가 필요하다. 이를 위해 본 논문에서는 유비쿼터스 커머스를 위한 다중 컨텍스트 기반 정보 서비스 기법을 제안한다. 제안한 기법에서는 동시에 발생하는 다중 컨텍스트에 대한 소비자의 관심 정도에 따라 컨텍스트별 정보를 효율적으로 서비스한다. 이를 위해 제안된 기법을 설명하고 유비쿼터스 커머스 어플리케이션 프로토타입에 적용한다. 또한, 시뮬레이션을 통해 본 논문에서 제안하는 기법이 기존 기법보다 우수함을 평가한다.

유비쿼터스 전자거래를 통하여 사용자는 언제 어디서나 네트워크에 접근하여 편리한 정보를 개인과 그룹, 그룹과 그룹 사이에서 교환할 수 있다. 사용자가 이러한 유비쿼터스 전자거래를 안전하게 사용하기 위해서는, 전자 정보의 무결성과 인증의 특성을 가지는 디지털 서명이 필수 조건이다. 유비쿼터스 네트워크에서의 디지털 서명은 언제 어디서나 필요에 따라 그룹을 만들기도 하고 해체하기도 하므로, 유비쿼터스 전자거래는 신뢰된 그룹 관리자와 셋업 프로시져 철회 프로시져 등이 필요 없는 디지털 서명이 요구된다. 따라서 본 논문에서는 안전한 유비쿼터스 전자거래를 위한 디지털 서명으로서 쓰레시홀드 링 서명을 제안한다. 제안된 디지털 서명은 위조의 위험이 없는(무결성) 링 서명과 메시지가 다른 서명자에 의해 서명되는 것을 증명할 수 없는 문제를 해결하는(인증) (n,t)링 서명을 사용한다. 그러므로 제안된 쓰레시홀드 링 서명은 무결성과 인증을 만족하는 차세대 유비쿼터스 그룹 서명이다.

Purpose In 2016, the market size of mobile(m-) shopping goes beyeond more than half of a total of online shopping. People use smartphones as the main device for m-commerce. Under the circmustances, this study attempts to address why people prefer to use smartphone-based m-commerce. In other words, it is necessary to understand the main value that smartphone-based m-commerce creates. Drawing on the studies of consumption value, this study focuses on utilitarian value in predicting customers' continuance intention in the context of smartphone-based m-commerce, recognizing that utilitarian value is a key extrinsic motivation in the goal-oriented, performance-oriented shopping contexts. Furthermore, this study identifies factors affecting customers' utilitarian value from the perspective of benefits and costs, following the notion that it represents the result of evaluating a trade-off of benefits and costs caused by smartphone-based m commerce. More specifically, in this study, ubiquitous service, location-based service (LBS), transaction speed, and price utility belong to the benefit dimension, whereas technology anxiety and cognitive effort belong to the cost dimension. Design/methodology/approach To test the proposed hypotheses, the study conducted partial least squares (PLS) analysis with a total of 294 data collected on users with experience in smartphone-based m-commerce. Findings The results show that first, utilitarian value is increased by the benefits, such as ubiquitous service, transaction speed, and price utility. However, LBS has no direct effect on utilitarian value. Second, the noteworthy finding is that ubiquitous service and LBS greatly increase transaction speed. Third, technology anxiety and cognitive effort considered as the cost dimension are negatively associated with utilitarian value but their impacts on it are non-significant. Finally, the results support the argument that utilitarian value is a determinant of continuance intention. Overall, the findings imply that utilitarian value greatly depends on the peception on benefits rather than the aspect of cost in smartphone-based m-commerce. Overall, the findings offer new insight into the studies of m-commerce by considering and verifying the impacts of its benefits and costs simultaneously.

The purpose of this paper is to review the major issues of between electronic trade and Ubiquitous computing. The rapidly developed environment by ubiquitous computing make the paradigm form e-trade to u-trade. This Article suggests an a-trade performance framework based on both field and literatures surveys. We propose some research subjects as well as practical implications for improving the performance of global c-trade under ubiquitous.

The internet and wireless communication technologies are creating ubiquitous environments in which various services are expected anytime and anywhere. Many hardware facilities have been developed and system structures are suggested for mobile services to realize a ubiquitous computing environment with appropriate quality. But these applications are not designed in the consideration of the general capabilities to perform user's wireless and mobile communication/transaction. Consequently, different needs from users are not sufficiently satisfied yet. In this study, we suggest structure of the emerging network system for mobile commerce that provides users with seamless and ubiquitous environments using location information which exploit context-aware technology.

According to the empirical study, the research model has been verified about the introduction of new ubiquitous technology into the Customs Information System. The research model is meaningful in deducing policy for accepting the new ubiquitous technology into the Customs Information System. The organization style is not yet positively accomplished, because of insufficient recognition about the new ubiquitous instrument. The other side the individual style, environmental style and working characteristics are contribute to accept the new ubiquitous environment, because of sufficient of education, usage and recognizing the usefulness of the portal information. It is established the Customs Information System with new ubiquitous technology such as RFID, DM, UCR etc.. for the usefulness and convenience.

With the advent of Ubiquitous era, Korean government understood its strategic importance and formulated 'IT839 Strategies' with various action plans not to miss the great opportunities which it may allow and eventually to realize u-Korea. As a result, m-Commerce is actualized and new types of Ubiquitous services such as digital multimedia broadcasting(DMB) and wireless broadband Internet(WiBro) are now on their commercial stages. Digital contents are the key success factors of these new services. Digital contents industry is regarded as next generation of growth engine in the digital economy, because it is knowledge-based and high value-added global industry affecting positively on the whole private and public sectors. This paper reviewed the characteristics, business models, technical and market trend of digital contents to be compatible with Ubiquitous environment. Also, it reviewed the development strategies of DMB and WiBro services, which are newly introduced and commercialized in Korea to make it as world leader in these fields. It may be concluded that Korea should make more efforts to development market-oriented digital contents for Ubiquitous era and to realize the sustained economic growth.
