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.

The office management service platform configured with office's sensor devices, G/DSCL(Gateway/Device Service Capability Layer), NSCL(Network Service Capability Layer), and NA(Network Application). In this paper, we designed gateway resource tree and service scenario to fit the office management service and demonstrated appropriate operation of the office management service through intelligent functional modeling.

이질적 분산 환경에서 전자 상거래는 신임장을 기반으로 상거래 참여자들에 대한 인증 서비스가 제공되어야 한다. 본 연구에서는 CORBA 보안 명세 1 를 기반으로 전자 상거래 참여자들에 대한 객체 단위 인증 및 권한 부여 기법을 제공하는 상호 인증 서비스 구조를 제안한다. 이 구조는 Kerberos 2 의 인증 기법 및 인증 키 교환 기법으로 전자 상거래 참여자간에 상대 주체의 신원 확인 뿐 아니라 거래 진행 중 취득한 정보의 근원을 파악할 수 있도록 하였다. 또한 Kerberos 기법을 CORBA 플랫폼 기반의 상호 인증 구조로서 분산 환경에 대해 확장하였으므로 키 관리 등 보안 정보 관리에 있어 효율적이다.Abstract Electronic commerce shall provide its subjects with a credential-based authentication service in the heterogeneous distributed computing environment. In this paper, based on CORBA security service specification 1 which OMG defined, we propose the mutual authentication service for subjects of electronic commerce, providing the authentication of object level and the authenticated key exchange. This proposed structure, by Kerberos 2 for the authentication and the authenticated key exchange, assures not only the identification of a partner but also the confidence of origin of business item for negotiations between subjects of electronic commerce. Since our deployed Kerberos is extended to the mutual authentication service based on CORBA platform, it is efficient for security administration to manage the information such as a key management in the heterogeneous distributed computing environment.

This paper proposes a bridge model for data exchange and service invocation between OPRoS and ROS platforms, shows the validity of the proposed model via applications, and compares the proposed model with the OPRoS platform and the ROS platform using performance measures such as data exchange time and service response time. The proposed model operates independently of OPRoS and ROS Platforms using its configuration file with mapping information among the OPRoS data/service port and the ROS topic/service. The configuration file makes easy connections between OPRoS data/service and ROS topic/service without changing the source code of the platform and components.

This paper focused on empirically testing the ESM(Electronic-Store Success Model). The model was developed by basing upon the ‘Updated D&M(DeLone and McLean) IS Success Model(2003)’ and reflecting the characteristics of marketing and e-business, and composed of the six dimensions including system quality, information quality, service quality, trust, customer loyalty and financial performance. The research model consisting of five dimensions, excluding financial performance, was proposed and empirically verified by structural equation model with respect to data from 224 customers on 69 Electronic-Stores. The results show that system quality and information quality significantly influence service quality, and that service quality also significantly influence trust and customer loyalty, and that trust has significant influence on customer loyalty.

Recently, as information and communication technology is swiftly developed, consumers feel more convenient in making use of as well as access to the banking service. This change must affect consumer's benefit, however, there are rare previous studies and methods for measuring it. Thus, we utilize hedonic price technique to estimate consumer's benefit of electronic banking information. The results indicate that the price elasticity of consumer's communication service expenditure regarding the use of electronic banking information is about 0.057%. That is, users have willingness to pay 57 Won more than current communication fee for acquiring the additional electronic banking information.

Product-service system (PSS) is a system of products and service, supporting networks and infrastructure that is designed to be competitive. PSSs satisfy customers' needs more effectively and have a lower environmental impact than traditional business models. Therefore, many companies and governmental institutes are eager to implement the PSSs as a new business model. In this paper, we focus on industrial practices as new business models for the company. PSS, especially, is popular in electronic industry, so one can often observe such examples as iPod, iPhone, e-Book and etc in the field. We first thoroughly investigate the current practices of PSS in Korean electronic industry. The examples are surveyed and projected directions are given. Then, non-electronic PSSs are surveyed. Especially mechanical PSSs are intensively discussed. Based on the survey results, we propose several major development strategies of Sustainable PSS (SPSS). SPSS will bring a competitive edge for company as realization of sustainable development of PSS considering economy, society, and environment.

The purpose of this study is to investigate the difference of performance between banks with electronic-based banking service and banks without electronic-based banking service in Korea. The performance indicators we use are DEA efficiency and profitability such as NI, ROA and ROE. The findings are that the performance of bank with electronic banking service are significantly different from that of bank without electronic banking service in DEA efficiency, financial efficiency(cost and revenue) and profitability. But there are some differences among the type of electronic-based service channel that banks provide. The banking channels comprise two major groups: the traditional channels and e-channels. E-channels provide cost-saving for banks and their clients. Among them, only card-related ATM significantly affects the profitability of banks in the positive direction, and technical efficiency also affects the bank's profitability. But the others do not affect.

This study analyzed the user behaviors of the electronic journal users and the influences of service quality of electronic journals on the customer satisfactions, customer loyalty, and frequency of visit to the library building. Approximately 60 percent of users prefer e-journal to printed formats. Service quality of electronic journal was measured by four dimensions: reliability of service, convenience of service, public relations, and user instructions.100 faculty members and 267 graduate school students were surveyed using questionnaires. It was concluded that each dimensions of service quality positively influenced on the customer satisfactions, and customer satisfaction positively influenced on loyalty, and negatively on frequency of visit to the library building.
