As the electronic market grows, the vendors establish internet shopping mall with a plenty of electronic catalogs and prepare to respond rapid electronic market growth. Consequently, building attractable electronic catalogs is very important to give a customer satisfaction. Based on prior researches, this study suggest a research model to understand the factors of electronic catalogs and their impact on the customer's relationship quality. As a result, this study confirmed that accuracy, timeless, interaction, presentation, and information structure of electronic catalog were important factors. And their impact on the customer satisfaction and trust were proved to be substantial. These results will contribute to provide implicit guidelines to the developers of internet shopping malls.

The aim of this paper is to identify the barriers to the B2B e-commerce development in China's pharmaceutical industry and to devise an effective strategy for its future development. Built on a detailed investigation of the market structure and recent development of electronic commerce in China's pharmaceutical industry, this paper proposes that the key issue in the development of effective B2B e-commerce business models is the successful transformation of the inter- organizational information systems into electronic marketplaces. In order to ensure the success of such electronic marketplaces, a government driven approach will be needed. In the process, designing an incentive compatible mechanism of coordinating the interest of all the market players will be the prerequisite.

This study aims to analyze users' assessment of electronic libraries in the mobile app market and promote service improvement based on this. To this end, the basic background and purpose of the research, research method, and research scope were first set, and the relevant literature and empirical prior studies were analyzed. Next, users' evaluations of electronic libraries were collected and analyzed from Google Play Store. Based on the results analyzed, measures to improve the quality of electronic libraries were discussed. Based on the results of the study, the following improvement measures are proposed. Need for systemic improvement and stabilization. Provision of applications suitable for multi-device environments. Resumption of services after systematic inspection after updating. Simplification of sign up, log in, and authentication procedures. User support through real-time chat. Introduction of a detailed assessment of reviews. Provision of guidance and user manual for electronic libraries. Improvements to expand user convenience, and Securing differentiation from other similar services.

The present paper presents a genetic algorithm (GA) to maximize social welfare and perform congestion management by optimally placing and sizing one Thyristor-Controlled Series Capacitor (TCSC) device in a double-sided auction market. Simulation results, with line flow constraints before and after the compensation, are compared through the Sequential Quadratic Programming SQP method, and are used to analyze the effect of TCSC on the congestion levels of modified IEEE 14-bus and 30-bus test systems. Quadratic, smooth and nonsmooth (with sine components due to valve point loading effect) generator cost curves, and quadratic smooth consumer benefit functions are considered. The main aims of the present study are the inclusion of customer benefit in the social welfare maximization and congestion management objective function, the consideration of nonsmooth generator characteristics, and the optimal locating and sizing of the TCSC using real code-based GA to guarantee fast convergence to the best solution.

전자금융에서 공인인증서 사용을 의무화한 정책에 대해 논란이 계속되고 있다. 이 논란의 근간은 다양한 사용자 인증기술 중 정부가 특정 기술에 기반한 공인인증서만을 표준으로 강제할 필요가 있는가에 대한 것이다. 본 논문에서는 전자금융에서 특정 기술에 기반한 공인인증서 사용을 의무화한 '공인인증서 의무화정책'의 도입과 폐지 효과에 대해 살펴봄으로써 정부의 기술표준화 개입의 효과를 분석하기로 한다. 본 연구의 주요 질문은, 첫째 정부의 개입 없이도 시장에서 단일 기술로 표준화가 형성될 조건은 무엇인가, 그리고 둘째, 시장에서 표준으로 결정된 기술이 사회후생을 극대화할 조건은 무엇인가이다. 본 논문은 이 질문에 대한 답을 통해 '공인인증서 의무화정책'의 도입과 폐지 효과를 살펴보았다. 본 연구에서는 시장참여자의 각 기술에 대한 선호도 유형과 차이가 '공인인증서 의무화정책'의 도입과 폐지로 인한 시장균형과 사회후생 수준을 결정한다는 것을 보였다.

This paper is aim to test how market orientation is related to the investment decision making. After controlling for firm-specific factors, this study finds a significantly positive relationship between market orientation and R&D expenditures, especially firms with high ratio of intangible assets and low ratio of abnormal inventory assets. Under conditions of low quality of earnings, the negative relation between market orientation and R&D expenditures is enhanced in electronic related industries. This indicates that the relation between market orientation and R&D expenditures may exhibit more reasonable patterns for investment decision of firms in technology driven business environment.

Like other communication networks, the Internet is establishing and reinforcing connections between market participants. By adapting to these networks, market participants are able to obtain the power of network to create new benefits in on-line markets. In this paper, we develop three stage non-cooperative game models to analyze the community related business market in electronic commerce where network externalities are present. It is found that, regardless of its market share, individual firm in a market tends to favor a community network. The analysis also shows there exist some possibilities that these community networks can trap the market in an inferior state when better alternatives are available to yield greater social welfare.

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.

The e-commerce market has been more diversified via B2B or P2P, and the size of this market has gradually been expanded as well. A noteworthy phenomenon is the P2P market, which has shown a rapid, approximately 200-fold or more increase in size since 2005. Specifically, the online secondhand-goods market that makes transaction easier and more convenient has attained a fast growth as well, but either sellers or buyers of secondhand goods are properly protected due to a lack of legal regulations on secondhand-goods transaction. The purpose of this study was to examine problems with online secondhand-goods transaction and to suggest some reform measures. There is something wrong with the legal status of brokers for secondhand-goods sales. According to the current law, individual brokers are neither mail-order sellers nor mail-order brokers. So they don't have lots of liabilities, and it means that the burden of risk is all imposed on buyers. Therefore it's suggested that individual brokers should be defined as 'involved operator of electronic commerce' so that proper liability might be imposed on them.
