Many companies have integrated their internal processes with the aid of information technology. Now the focus is on interconnecting trading partners. Collaborative commerce (also known as c-Commerce) has a key role. It is not just about making it easier for business to communicate. It is about by breaking down barriers along the entire length of the supply chain. Some c-Commerce links are permanent, others get established when and where they are needed. c-Commerce is helping business in electronic supply chains to improve product delivery while cutting costs, to strengthen relationships and to reduce lead time. In this paper, we propose the concept of collaborative commerce, and design and implement Collaborative Commerce Portal (CCP) system of small and medium enterprise for marketing support. The technical definition of CCP is set of all technical elements can do collaborative commerce between small and medium enterprises with Internet or Internet. The target information of CCP includes usual and unusual information and all other information of companies used as process events. Through this, it enhances efficiency of business processes, core information sharing and marketing activation.

The purpose of this study is to identify the critical factors for the successful implementation of e-business in the public sector. The paper reports on a case study of the 'Onbid' asset-management system developed by the Korean Asset Management Corporation (KAMCO). 'Onbid' system is an e-marketplace for trading in public assets, including the disposition by public sale of real estate. Through this case study, the paper: (i) explores the changes in organizational culture that are required for successful e-transformation in organizations of public sectors; and (ii) identifies the critical success factors for the implementation of e-business in the public sector.

In an electricity market, the spot market is normally integrated with a forward or future market. The advantage of the forward market is to allow the market participants to deal in a part or the whole trading portfolio at a fix price in advance and to avoid risk associated to the uncertain price of the spot market. Japan has introduced a continuous auction base forward market from April 2005. This paper analyzes the Japanese forward market rules and operations, and introduces a new algorithm that may improve the efficiency of the market itself. The proposed algorithm enables us to give consideration to the specific characteristics of the power system and to integrate them in the auction mechanism. The benefits of the proposed algorithm are verified on an electronic simulation platform and the results described in this paper.

So far. the common elasticity data of textile fabrics has not been present because the method depends on the knowledge of measurement operators. In this paper, the new measurement equipment using road cel1 is presented to measure the coefficient of textile fabrics in real time. The measurement method is based on the volta among textile fabrics. The textiles with strong elasticity are high voltage produced from others are low. The presented method can be applied to visualize the textile, sew the cloth, control textile fabrics. Also. these measurement datum are used to B2B electronic trading system.

본 논문은 B2B(Business To Business)전자상거래상의 거래기업에 대한 신뢰도 및 경제동향에 따른 거래기업의 변동율을 예측 분석하는 모형을 제시한다. 거래기업의 자금흐름은 거래기업의 은행으로부터 움직이게 되고, 따라서 거래하고자 하는 신뢰도는 그 거래대상 기업의 성장성이나 자금흐름 등과 같은 기본적인 재무비율 보다는, 거래기업은행에서 바라 보는 거래기업의 신뢰성이라는 측면에 비중이 더 실린다. 본 논문에서는 이러한 모형에 대한 알고리즘 설계 및 인터페이스 관한 설계를 하고, UML(Unified Modeling Language)을 이용하여 Component 로 구현을 한다.

In this article we examine a unique data set of intraday fair disclosure(FD) releases to shed light on market efficiency within the trading day. Specifically, this paper analyze the response of stock prices on fair disclosure disseminated in real-time through KIND(Korea Investor's Network for Disclosure) on Korea stock exchange during the period from January 2003 to September 2004. We find that the prices of stock experiences a statistically and economically significant increase beginning seconds after the fair disclosure is initially announced and lasting approximately two minutes. The stock price responds more strongly to fair disclosure on smaller firm but the response to fair disclosure on the largest firm stock is more gradual, lasting five minutes. We also examine the profitability of a short-term trading strategy based on dissemination of fair disclosure. After controlling for trading costs we find that trader who execute a trade following initial disclosure generate negative profits, but trader buying stock before initial disclosure realize statistically significant positive profit after two minute of disclosure. Summarizing overall results, our evidence supports that security prices on Korea stock exchange reflects all available information within two minutes and the Korea stock market is semi-strongly efficient enough that a trader cannot generate profits based on widely disseminated news unless he acts almost immediately.

In terms of B2B, business partners require works that define their ability to operate business collaboration. The document outlining collaboration is the basis of improving the system of business partner and its interoperability. In addition, the definition of business interaction that is bastd on the documents demonstrating inter-cooperation of business companies is needed to function interoperability properly, and business trading is performed depending on the documents that define reciprocal action of collaboration. In ebXML, CPP(Collaboration-Protocol Profile) defines one business parter's technical capabilities to engage in electronic business collaborations with other partners by exchanging electronic messages. A CPA(Collaboration-Protocol Agreement) documents the technical agreement between two partners to engage in electronic business collaboration. In this paper, 1 draw up a plan for a system that deals with business collaboration document to ameliorate the interoperability of B2B companies.
