This paper is a study on the model that measures economic values for the non-market properties of Electronic Commerce(EC). For development of this model, first of all, we reviewed the properties of EC service, and looked around the relation between customer satisfaction and/or payment value and EC properties. In addition, we checked the method to measure economic values of these properties. This measurement method is the contingent valuation method which is a method of measuring the value of the environmental product. We modified it to adapt to the EC. Finally, in this paper, we proposed an economic value model which measures the value of willingness to pay(WTP) to our objectives. However, there could be some restrictions at the time when surveying empirically. Therefore, the succeeding study should be done in order to improve these restrictions some day.

최근 전세계적으로 전자상거래(electronic commerce, EC)가 초미의 관심사가 되고 있다. EC는 크게 기업과 기업간(business-to-business, B2B)거래, 기업과 소비자간(business-to-consumer, B2C)거래, 정부와 기업간(government-to-business, G2B)거래, 그리고 소비자와 소비자간(consumer-to-consumer. C2C)거래로 구분할 수 있다. 그 중 B2C의 대표적 형태인 인터넷 쇼핑의 확산은 시간, 거리, 장소의 제약을 초월하여 상품정보, 대금지불, 배송까지 일괄처리하기 때문에 소비자에게는 편리함, 경제성 및 쇼핑의 즐거움을 제공하고 기업에게는 시장범위 확대, 거래비용 감소 등의 효과를 가져온다. (중략)

Recently, many companies and consumers are using Internet to sell and buy goods and manage their businesses. And for most companies, they have Electronic Commerce system and Enterprise Resource Planning (ERP) system. But the two systems manage separately and the data are not integrative. So it is hard to mangement the system alike and the costs may be higher than the system which has intergrated information. ebXML-based Electronic Catalog (e-Catalog) can provide intergrated information. In this paper, we took a manufacturing industry company for example. We planned to construct the e-Catalog System, analyze the products of the company as well as design e-Catalog system using ebXML to connect EC with ERPs.

The acceptance of enterprise resource planning (ERP) system in the industries is essential to enhance the enterprise-wide productivity and global competitiveness. In this study, we first describe the needs for the ERP system and the structural backgrounds of the system. Then we suggest our strategies for the implementation of the standard ERP system under the small and medium enterprises (SMEs).

21세기 고도 정보화사회를 맞이하여 기업의 경영활동은 컴퓨터 네트워크 환경에 의존할 수밖에 없는 환경에 이르렀으며 인터넷을 이용한 비즈니스 전략이 경영전략의 새로운 핵심으로 부상하고 있다. 인터넷의 빠른 확산은 기업의 전통적인 거래환경에 급격한 변화를 야기시키며 가상공간에서 상품과 서비스를 사고 팔기 위한 전자상거래(Electronic Commerce: EC)시장이 급속히 형성되고 있다. (중략)

EC(Electronic Commerce) which is cone the virtual space through Internet, has the advantage of time and space. On the contrary, it also has weak point like security probelm because anybody can easily access to the system due to open network attribute of Internet. Theretore, we need the solutions that protect the EC security problem for safe and useful EC activity. One of these solution is the implemonlation of a strong cipher algorithm. YK2(YoungKu Kang) cipher algorithm proposed in this paper is advantage for the EC security and it overcomes the limit of the current 6/1 bits block cipher algorithm using 128 bits key length for input, output, encryption key and 32 rounds. Moreover, it is degigned for the increase of time complexity and probability calculation by adapting more complex design for key scheduling regarded as one of the important element effected to enciyption.

With the proliferation of EC, many customers have been participating into online auction or group-buying market over searching internet shopping-malls to purchase goods. To support the customer's convenient transaction, lots of agent systems are developed to facilitate the customer's product brokering, merchant brokering, and negotiation of transaction. However, many of these systems have focused upon supporting transaction at only one type of marketplace. Since these marketplaces have different transaction settlement mechanism, it is necessary to develop the system that utilizes the customer's transaction including the selection of the type of marketplace to buy. Then we classify the kinds of B2C electronic marketplace according to the protocol by which the market operated. The structure of negotiation message is developed using XML schema and RDFS under the characteristics and message example of each marketplace in this research.
