In recent years, electronic commerce (EC) business has shown a tremendous growth, which put additional cognitive and time-consuming loads on the human users. Intelligent software agents are one key technology to support users doing real EC-business.We propose an Agent-based Business-to-Business(B2B) Marketplace on Internet, where constituent members cooperate or compete in order to get the best possible deals, with the aim of reducing user loads.In case of B2B deals, the good itself shows a complicated behaviour, e.g.price discounts depending o the lot, discounts for cross-buying and so on. It is impractical to concentrate all the knowledge about the goods and the trading strategies at the buyer/seller side. Instead, we include such information in the good itself, which allow us to model the goods as being agents.

Even though B2B EC is becoming popular, there have been not so much studies about performance evaluation methodology for B2B systems. In this paper, after analyzing buyer-carts systematically focusing on the buyer's interactional efforts on the typical buying processes of each buyer-cart, we propose a quantitative performance evaluation model. For this, we categorize buyer-carts in B2B EC as s-cart, i-cart, and b-cart depending upon its residing sites: seller, intermediary, and buyer sites. And after proposing the desired features of buyer-carts in B2B EC as identification, collection, trashing, ordering, payment, tracking, recording, purchasing decision support, and transmission of records to e-procurement systems, we derive a performance evaluation model by calculating detail sub-processes from the desired features' viewpoints. By setting variables from a survey on the actual condition of using buyer-carts in companies in Korea, we try to evaluate the performance of buyer-carts in B2B EC. In this paper, we suggest a new methodology of performance evaluation for B2B systems, and show that the b-cart platform is more efficient than other buyer-carts especially in B2B EC.

Nowadays, the explosive evolvement of Internet. which is referred to as EC, has been prevailing. That has given the chance all of the world consumers to contact all of the world companies to enter into business relationship. But, electronic commerce laws have been established per conventional jurisdiction. some legal issues take place in the field of cross-border electronic commerce, including the governing law and competent courts. In this situations, it is gradually and widely required to lay down the internationally harmonized electronic commerce legal framework. Now, there are a lot of legal issues assumed in EC, in this study, we studied three precedence problems concerning B2C: Consumer Protection Law regarding B2C, Personal Information Protection Law in Private Sector regarding B2C, Web Site Trust Mark System.

Electronic catalog is a kind of electronic document to exchange product and service data for B2B or B2C EC(electronic commerce). Up to date a lot of selution/service providers which develop EC systems such as shopping malls, have constructed electronic catalogs. However, they use different contents, formats, and exchange methods without a standardized concept and consistent definition of components. This causes problems that time and cost to develop catalogs are duplicated and data exchange across e-marketplaces is difficult. In order to resolve these problems, standardization works for electronic catalog are carried out inside and outside the country. In this paper, we introduce types of standards concerned with electronic catalog, trends of standardization activities, and domestic standardization activities by industry such as electronics, automobile, shipbuilding, heavy industry, steel, electricity, construction, distribution, biomedical, and textile.

Product catalog information is the most important factor to make customers purchase the product for various B2B or B2C businesses provided on the Internet. As catalog information differs from company by company, it cannot provide common criteria standard to customers to make decisions. Therefore, it is necessary to develop a platform independent system, which integrates incompatible data from each company' catalogs and manages its database. This paper describes the integrated E-catalog system made up DB module, catalog management module, and interface module. This system allows customers to view standardized product catalog information from different companies with real -time updates, and also provides extensibility, flexibility, and interoperability for the effective E-Business management.

Electronic Commerce (EC) has been at the center of discussion as a symbol of the integration of unprecedentedly developed Information and Communication Technologies (ICTs) and traditional commerce. In spite of much attention to EC, the research from a spatial perspective has not proliferated yet. EC was regarded to have aspatial characteristics based on the expectation for a global expansion of business activities in a digital economy. This paper attempts to figure out the spatial characteristics of public Business-to-Business electronic marketplaces (public B2B e-MPs), as one of the most evolving forms of B2B EC, regardless of the low proportion in B2B EC at present. Many of the firms operating public B2B e-MPs in Korea were located in Seoul, especially in Gangnam-gu. The analysis of three spatial indices showed their extreme spatial concentration. The analysis on the location factors of Public B2B e-MP firms in Korea demonstrated that location factors of public B2B e-MP firms were differentiated by regional groups: Gangnam-gu, Seoul except Gangnam-gu, and the provinces. It was againt an initial extreme expectation that the firms relevant to B2B EC will not care about physical locations because they mainly do businesses in electronic space. The differences between those in Gangnam-gu and in the provinces were strikingly prominent. Such differentiated location factors by region were closely related to the different attributes of the public B2B e-MPs by region. In conclusion, public B2B e-MPs are not irrelevant to physical space and physical proximity, at least at a current stage. Customized spatial strategies are required for successful online businesses.

Emergent requests or urgent information among enterprises require their intimate collaboration in B2B EC (electronic commerce). This paper analyzes the needs of intimate cooperation of distributed EC systems in terms of business contracts and presents an active rule-based methodology of close cooperation among EC systems and an active rule component to support it. Since the rule component provides high level rule patterns and event-based immediate processing, system administrators and programmers can easily program and maintain intimate cooperation of distributed EC systems independently to the application logic. The proposed active rule component facilitates HTTP protocol. Its prototype is implemented in B2B EC environment and evaluated using basic trigger facility of a commercial DBMS.

This study is focused that the electronic commerce(EC) on the purchasing section may improve the efficiency and transparency of the hospitals management. After reviewing the purchasing activity of hospitals, I study the introduction, expected effects, and problems of EC. So, I am going to provide basic information for activating EC. The samples are managers of 170 hospitals, which are located on Seoul. As a result of collection this survey, I analyze 79 hospitals. For data analysis, I use $X^2$-test and ANOVA for purchasing management and the relevance of EC according to the level of care. The results of this study are 1. The problems on the management of purchasing section are: firstly, they don't have sufficient time to study market. Secondly, it is difficult to find competitive suppliers. And, lastly, they cannot gather a lot of information about the price of products. 2. There are many answers of the needs on the introduction of B2B. However, some hospitals think they don't need it. But, the most answers are that the EC will be settled within 4 years. So, we can realize that these hospitals are getting interested on the EC. On the other hand, I find that they prefer outside EC companies for the introduction of EC. 3. On the expected effects on EC, first is the effectiveness of the market survey. The next is to collect information of adequate price of products owing to clear transaction, find easier new suppliers and gather useful data. 4. On the external problems of the introduction of EC, there is low credibility related to the security and the weakness of suppliers' information system. Especially, on the Real Transaction Price Payment system, the bigger bed size, the higher understanding on these problems. On the internal problems of the introduction of EC, first is the burden of the introduction of EC and operating cost. Especially, on the burden of the disclosure of revenue source, the smaller bed size, the higher understanding on this problem So, this is a point which deserves my attention statistically. However, this shows relatively little understanding about incomplete the standard of product category and the weak information system of hospital. Through this study, I am going to suggest 3 points for the activation of the introduction of EC on hospitals. 1. The reform of the Real Transaction Price Payment System on medical supplies and materials for medical treatment 2. The establishment of the standard of product category 3. The promotion of information system based on network.
