현재 많은 기업들은 인터넷을 기반으로 Intranet, Extranet등을 구축하며 기업간 전자 상거래에 활발한 움직임이 있다. Extranet은 WWW으로 대표되는 인터넷 기술을 사용한 기업간 정보 시스템이라 할 수 있고, 종래의 기업간 정보시스템 보다 훨씬 구축하기 쉽기 때문에 Extranet의 수요는 점점더 확산되고 있는 추세이다. 즉 Intranet에서 Extranet으로 기업의 정보 시스템이 확대되기 시작했다. 그러나 Extranet은 Intranet과는 달리 영업데이타가 공용 통신 회선을 타고 전송된다든지 다른 회사의 사용자가 사내 서버에 액세스해 들어오기 때문에 반드시 고려돼야 할 과제가 보안(Security) 문제이다. 즉 어떤 거래에 대한 데이터의 전달과정에서의 변조 및 누락이 없었는지 거래자가 거래사실을 부인하지 못하게 하는 조치, 혹은 제3자가 거래내용을 도청하지 못하게 하는 조치와 내부에 보관된 정보를 허가받지 않은 사용자가 알지 못하게 한다든지 하는 조치가 반드시 필요하다. 따라서 본 연구에서는 Web기반 CALS시스템 구현에 있어 보안성을 확보하기 위하여 내부 정보보호를 위한 미들웨어 구현, 인증 및 접근제어를 위한 Proxy구현 기술, 인증 및 데이터 보호를 위한 암호화 기술등을 확보하여 이에 대한 시제품의 개발과 구현에 관해 알아보고자 한다.

This study investigates the effects of M&A experience of Chinese firms and characteristics of deal partners in cross border M&A deal failures. 1,610 firms that participated in 1,558 cross border M&As from 2000 to November 2015 are used as samples. The dependent variable is the M&A transaction failures, which were cases of deal pending or withdrawal of Chinese firms. Major independent variables are the nationality diversity of transaction partner firm, the partner firm belonging to a developed country, domestic M&A experience of the Chinese firms, M&A experience in a particular target country, etc. After conducting a probit model analysis, we find that deal partner firm's nationality diversity increases the failure rate of M&A. While prior domestic M&A experience in China has no influence on deal failure, prior M&A experience of Chinese and focal firms in a particular country have a negative effect on the probability of deal failure. This study has academic implication on figuring out why firms are likely to fail in the process of strategic activities based on the inter-organizational learning through partnerships perspective.

The industrial community in a metropolis has played an essential role to keep business in a large city. This paper aims to analyze the realities of trade network among enterprises at Buksungro Tools Commercial Cooperative in Daegu. The urban style industrial community is found at Buksungro in Daegu. There are more than one hundred small-sized enterprises. Major trades among enterprises are occurred within and/or by the area. The long-term trade networks within the Buksungro Tools Commercial Cooperative have played the key role to maintain the industrial community. The trade relationship has depended on business networks based on social capital rather than commercial mechanism. The trade networks have been established through credit transactions as well as handling troublesome orders. The trade networks help to transfer technology and to learn the tacit knowledge among firms. The long-term trade networks are more influenced by the social accessibility than spatial accessibility.

Currently, many enterprises are trying to allocate the investment costs and risks through collaboration, and strengthen their competitiveness by sharing their resources and gains. Intercorporate sharing economy, a type of intercorporate collaboration, refers to the economic activity to share the idle resources of enterprises and enhance their efficiency. For a successful intercorporate economy with the participation of various stakeholders, there is a need to establish the clear allocation method of gains. Accordingly, this study suggested three methods-the MST method that can apply transaction cost incurred when forming a coalition for sharing economy; the average of transaction cost incurred by each participant, and the Shapley Value application method for the transaction cost incurred between the participants. In addition, this study also suggested gain allocation methods such as the "Equal distribution of gain" method, a gain allocation method based on the Cooperative Game Theory, the the "Proportional distribution of gain" method, and the Shapley Value method that takes in consideration the transaction costs.

The growth of electronic commerce make business to business electronic commerce market grow dramatically due to dramatic decrease of transaction cost and increase of productivity. It also influences the way of building transaction relationship between buyers and suppliers. This study tends to prove electronic market theory for Internet based 13213 commerce. We observe and analyze the implementation and usage patterns of procurement system of I company. The result shows that even through Internet enable many buyers and suppliers to participate and transact each other, the transaction pattern is different according to asset specificity and uncertainty as follows. First, with adoption of internet, the product with the higher asset specificity rather than lower asset specificity can be easily purchased. Second, Internet doesn't make any significant influence on the transaction of the product with higher uncertainty. But, organization's pre-audit process can indirectly influence on the decrease of the transaction uncertainty.

E-business automates overall activities in a company and allows distributed systems to communicate their information. The automation and information sharing improves its productivity and responsiveness. B2B workflow systems progress their business processes electronically and help the companies to monitor their execution and administrate the processes. This research analyzes the technologies and standards for B2B workflow integration, and proposes three approaches to implement effectively workflow integration. We analyze several existing workflow standards and business process definition languages, and compare their structures and features. And we examine the messaging technologies and architectures to implement business integration. Finally we extract a reference model for B2B workflow integration, and propose three types of workflow integration and implementation designs. This research helps companies to understand the workflow standards and the messaging technologies for B2B workflow integration, and to implement workflow integration systems that are suitable for their e-business environments.

In terms of B2B, business partners require works that define 1h13ir 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 based 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 partner'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, I draw up a plan for a composer system that deals with business collaboration document to ameliorate the interoperability of B2B companies.

최근 기업간 거래는 인터넷을 기반으로 하는 기업간 전자상거래(B2B: business to business electronic commerce)로 시간과 공간을 초월하여 이루어지고 있다. 따라서 국내·외 많은 기업들은 인터넷 기반의 비즈니스와 정보교환으로 업무 효율화 및 기업 경쟁력 강화에 중점을 두고 있다. 최근 온라인 환경의 인터넷 EDI 방식에 많은 기업들이 관심을 가지고 있으며, 전통적 EDI방식의 문제 해결방안으로 웹 문서를 많이 활용하고 있다. 또한, 현재까지 웹 문서는 HTML을 사용하여 정의되고 있는데, 이러한 HTML은 간편한 사용과 높은 이식성을 가진다. 그러나 기업간 발생하는 다양한 문서양식을 표현하기 힘들며, 기업간 서로 상이한 정보시스템에서 발생되는 거래 데이터 등의 통합이 불가능하다 그래서 최근 HTML의 한계를 극복할 수 있는 새로운 언어로 XML이 등장하여 인터넷 기반의 B2B에서 기업간 정보 교환에 적용되어 질 수 있다. 따라서 본 연구에서는 기존 웹 기반의 기업간 수주처리시스템에 XML 언어를 사용한 기업간 데이터 통합 방안을 제시한다. 또한 이를 ‘H’기업에 적용하여 프로토타입 시스템을 구현하고, 그 기대효과를 제시한다.
