In this paper, m(mobile)-commerce system based on LBS is implemented. WIPI(Wireless Internet Platform for Interoperability) that supports COD as a mobile VM(Virtual Machine) is used. These experimental results show that the system we proposed could be very efficient for CRM(Customer Relationship Management) and target management. And also, server load and connection time is improved by this system. From now on mobile commerce system based on LBS can be usable at various areas in ubiquitous environment.

An electronic commerce model is proposed which distributes digital content in mobile environment. This model resolves the problems caused by various digital content and complex distribution structure. The online distribution systems under the wireless environment include many different factors from the conventional offline and wired networks. Furthermore, the multimedia content may be propagated more easily and illegally. The scheme to protect the rights and profits of people related to the copyrights of digital content is needed. In this paper a framework for electronic commerce of content distribution under the wireless environment based on MPEG-21 is proposed. This model can be applied to the digital rights management system and utilized to protect the rights of trading entities in online distribution of electronic commerce.

This paper propose not only MDIT(Mobile Digital Investment Trust) agent design for Trust Investment under Mobile E-commerce environment, but also the symmetric key algorithm 3BC(Bit, Byte and Block Cypher) and the public encryption algorithm F2mECC for solving the problems of memory capacity, CPU processing time, and security that mobile environment has. In Particular, the MDIT Security Agent is the banking security project that introduces the concept of investment trust in mobile e-commerce, This mobile security protocol creates a shared secrete key using F2mECC and then it's value is used for 3BC that is block encryption technique. The security and the processing speed of MDIT agent are enhanced using 3BC and F2mECC.

Since component-based development technologies support reusability and enhance productivity of application development, they are adopted for rapid and efficient software development, and among them, EJB component is a Jana-based software development technology widely used in industry. In this paper, we designed and implemented bulletin board and shopping mall which are major constituents of mobile e-commerce system using EJB components, and suggest construction guideline supporting reusability and interoperability.

최근의 전자상거래는 유선인터넷 환경의 e-커머스와 모바일 커머스를 새로운 차원으로 확장한 u-커머스(ubiquitous)시대로 발전하고 있다. 따라서 온라인과 오프라인 매장의 상거래 데이터 연동과 유선과 무선인터넷 환경의 채널을 통합함으로써, 언제 어디서든지 고객의 모든 데이터를 수집하고 다양한 매체를 통해 고객관리를 할 수 있는 전자상거래 솔루션이 요구되어진다. 본 연구는 온 ${\cdot}$ 오프라인 매장에서 수집된 각종 데이터를 바탕으로 데이터마이닝을 통한 고객의 성향을 분석하여 고객의 요구사항을 미리 파악하고, 이를 마케팅에 적용하여 고객의 유지율을 상승시키고 해당 회사에 대한 충성심을 유도하여 이익을 증대 시킬 수 있는 시스템을 연구하였다.

Along with the advent of ubiquitous computing environment, it is becoming a part of our common life style that the demands for enjoying the wireless internet using intelligent portable device such as smart phone and iPad, are increasing anytime or anyplace without any restriction of time and place. The recommending service becomes a very important technology which can find exact information to present users, then is easy for customers to reduce their searching effort to find out the items with high purchasability in e-commerce. Traditional mining association rule ignores the difference among the transactions. In order to do that, it is considered the importance of type of merchandise or service and then, we suggest a new recommending service using mining sequential pattern based on weight to reflect frequently changing trends of purchase pattern as time goes by and as often as customers need different merchandises on e-commerce being extremely diverse. To verify improved better performance of proposing system than the previous systems, we carry out the experiments in the same dataset collected in a cosmetic internet shopping mall.

인터넷의 보급이 급속히 확대됨과 동시에 전자상거래가 급속도로 증가하고 있다. 지금까지는 컴퓨터를 통한 전자상거래가 대부분을 차지하였으나 무선이동 통신의 보급이 급속도로 빨라지면서 무선통신을 통한 전자상거래인 m-Commerce가 부각되어지고 있다. m-Commerce를 원활히 하기 위해서는 필요한 대역폭과 단말기의 프로세싱 파워와 자원이 확보되어야 한다. 그러나 무선이동 통신에서는 일반 유선 통신과는 다르게 많은 제한 사항들이 있다. 이동 통신에서 가장 크게 고려해야 할 사항들은 핸드오프와 무선이동 단말기의 부족한 자원을 들 수 있다. 005를 지원하기 위한 기존의 대역폭 예약 시스템에서 여러 가지 인자를 사용하였으나 본 논문에서는 셀 간 체류하는 시간인자와 가장 최근의 사용자 패턴인자를 적용하여 더욱더 좋은 005를 지원하여 대역폭을 낭비하지 않고 최대한 활용하는 시스템들 설계하고 구현하고자 한다.

빠른 환경변화와 더불어 다양한 인터넷 사업 모델이 계속 새로 등장하고 있으며, 시장의 성숙에 따라 일부 사업 모델은 수명을 다하고 새로운 모델에 의해 대체되거나, 조금씩 변형된 형태로 발전하거나 여러 유령의 모델이 합해져 다양한 새로운 모텔로 다시 태어나고 있다. 그 중 전자상거래는 더 이상 새로운 기술이 아닌 우리 환경의 필수적인 요소로 자리잡고 있으며 국내에서도 전자상거래 시장이 기존의 오프라인의 상점을 온라인 상으로 이동시키려는 움직임이 활발한 상태이다. 이러한 요구에 부응하기 위하여 본 논문에서는 전자상거래를 위한 시스템을 UML (Unified Modeling Language)로 설계하여 시스템의 특성에 맞게 사용자가 시스템을 사용할 수 있도록 한다.

O2O(Online-to-offline) service is the new commerce system form that mixed information search and payment of products and services from online and receipt of goods from offline. O2O commerce combine advantage of existing electronic commerce and redeem the critical point of each commerce circulation method, but earnings model is still lacking compared to development speed of O2O technology. Therefore this study drew common factor applied to O2O service to search success factor of O2O commerce on the point of view as a customer Centered by existing B2C electronic commerce, Mobile commerce, and service quality model of offline commerce included O2O commerce method. Further we suggest O2O success factor model combined new O2O success factor additionally reflecting qualitative research result based on drew O2O success service Quality factor.
