In this paper an attempt is made to understand contribution factors in the field of electronic commerce(EC). To do that, we adopt and modify an existing commerce model. The following two major conclusions are drawn from our simulation. Most of all, the diminution of information delay introduce monotonous growth rather than fluctuation of EC market. The stable increase of revenue or market scale makes us decide the employment or capacity scale quickly. Second, for favorable and continuous evolution of EC, utilization system of electronic money should be established steadily. The following findings strongly support our claim: We found full oscillation of EC market when electronic money system didn't established well. On the contrary, if electronic money system could provide fast cash flow and fully trustful function, decisions of company or consumer would be executed promptly.

As a way to allocate lots of orders to many participants for vehicle allocation problem, this study has used an agent negotiation based reverse auction model. This agent negotiation provides coordination functions allowing all participants to make a profit, and accomplishing Pareto optimum solution from the viewpoint of a whole trucking cargo transportation network. In order to build a strategic cooperation relationship based on information sharing, this agent negotiation provides a coordination mechanism in which all the participants including consignors, brokerage firms, and car owners are able to attain their own profits, and also that ensure a competitive market. This study has tried to prove that the result of an agent-based negotiation is the Pareto optimal solution under the present market environment. We established a mathematical formulation for a comparison with the Integer Programming model, and analysing e-Marketplace, structure of shipping expenses and brokerage system in the trucking cargo transportation industry.

This study shed light on the status of Korean Kimchi industry in overseas markets and presented methods for promoting Kimchi industry of Gwangju Jeonnam metropolitan city and stimulating the export of Kimchi produced in Gwangju Jeonnam, a city that has come to the fore as the center of Kimchi industry, which aimed to explore the ways of ratcheting up competitiveness of Kimchi industry in the global market as Kimchi has become more likely to be globalized amid the recent "Korea Trend" boom and the growing consumption of fermented food. Therefore, methods for promoting Kimchi industry and stimulating the export of Kimchi should be explored to ensure the promotion of Kimchi industry and the stimulation of the export of Kimchi, ultimately restoring the status of Korea as the home of Kimchi, in consideration of the great spillover effect on the regional economy, through a series of measures such as the clusterization of Kimchi industry, expansion of cultural experience projects related to Kimchi for the globalization and the increased consumption of Kimchi, government support to increase Kimchi companies in size and achieve the modernization of Kimchi companies, introduction of Kimchi KS audit system and quality certification system, development of new product targeting global market and making Kimchi a high-end product, expansion of export, support of export market diversification, assurance of safety and price competitiveness of Kimchi, differentiated production and marketing strategy by means of technological research, and others.

최근 섬유 및 의류산업의 시장변화가 공급자 중심에서 소비자 중심으로 빠르게 진행되고 있다. 이러한 경향은 소비자의 다양한 요구와 패턴의 다양성을 반영시켜서 시장의 변화에 빠르고 유연하게 대처할 수 있는 물류 공급망 관리 (Supply Chain Management, SCM) 시스템의 필요성을 크게 부각시킨다. 그러나 전통적인 SCM에서는 바코드를 기반으로 생산에서 유통까지 공급망 관리가 이루어지고 있기 때문에 실시간으로 정보를 공유하고 시장의 환경변화와 소비자의 요구에 신속하게 대응하는데 한계가 있다. 이 논문은 새로운 섬유 및 의류산업에 최적화된 RFID 기반의 u-SCM 시스템을 제시한다. 제안 시스템의 특징으로는 RFID 에 기반함으로써 SCM의 생산 및 유통 정보를 실시간으로 수집하고 효과적으로 활용할 수 있다는 것과, 웹 서비스 모듈을 이용하여 레거시 시스템과 유기적으로 연계시킬 수 있어 시장 및 고객요구의 변화에 빠르고 유연하게 대응할 수 있도록 하는 것이다 제안한 시스템의 특정을 구현을 통하여 확인하였다.

사이버 주식거래가 증가함에 따라 홈트레이딩 시스템을 이용한 주식거래가 활발해지고 있다. 홈트레이딩 시스템은 개인투자자 대다수가 이용하는 방법으로 코스닥에서는 75%도 가장 큰 비중을 차지하고 있으며, 코스피에서도 40%의 점유율을 기록하고 있다. 하지만 홈트레이딩 시스템은 사용자의 속도와 사용자 편의성에 초점을 맞추고 있어 보안기능이 다소 미흡함을 발견하였다. 본 논문에서는 홈트레이딩 시스템 사용시 메모리에 인증정보가 평문으로 남는 취약점을 기반으로 메모리 덤프 툴을 이용하여 주식부정거래 가능성을 분석하고 휴대전화 SMS를 이용한 투채널 인증으로 주식부정거래에 대응할 수 있는 인증기법을 제시한다.

Recently in Korea, YouTube stock channels increased rapidly due to the high social interest in the stock market during the COVID-19 period. Accordingly, the role of new media channels such as YouTube is attracting attention in the process of generating and disseminating market information. Nevertheless, prior studies on the market forecasting power of YouTube stock channels remain insignificant. In this study, the market forecasting power of the information from the YouTube stock channel was examined and compared with traditional news media. To measure information from each YouTube stock channel and news media, positive and negative opinions were extracted. As a result of the analysis, opinion in channels operated by media outlets were found to be leading indicators of KOSPI market returns among YouTube stock channels. The prediction accuracy by using logistic regression model show 74%. On the other hand, Sampro TV, a popular YouTube stock channel, and the traditional news media simply reported the market situation of the day or instead showed a tendency to lag behind the market. This study is differentiated from previous studies in that it verified the market predictive power of the information provided by the YouTube stock channel, which has recently shown a growing trend in Korea. In the future, the results of advanced analysis can be confirmed by expanding the research results for individual stocks.

Despite extensive researches and pre-market clinical trials, only limited information on the adverse drug reactions (ADRs) of a drug can be collected at the time of market approval from regulatory agency. ADRs constitute a major public health problem. Post-marketing surveillance of drugs is important to detect signals for ADR. In Korea, one of the main methods for monitoring the safety of marketed drugs is spontaneous reporting system of suspected ADRs. Re-examination and re-evaluation system are in force for monitoring safety of new market approval drugs and currently under marketing drugs, respectively. Recently, regional pharmacovigilance centers were designated from Korean Food and Drug Administration for facilitating ADR surveillance. Over recent years, with the development of information technology, there has been an increased interest in establishing data mining system for detecting signals from Health Insurance Review Agency database. The purpose of this paper is to review the current status of Korean ADR surveillance system and suggest the possible solutions for developing active pharmacovigilance system in Korea.

Services could move over the world where they want to go. Especially, travel services shared 29.4 percent of total world exports, 625 billion dollars in 2004 (WTO, 2005). Tourism is a very important sector in service trade in the world. Of developing countries, Korea has been experiencing remarkable development in female outbound travel market since the complete liberalization on overseas travels in 1989, with about 3.85 million travelers in 2005, 2,000 percent growth rate over 1988. It means woman's social status has been increasing in Korea. Especially, in the study young housekeepers, solely office ladies, and college students were described as very important market segments in Korean woman outbound travel market. They were not only major decision makers, but also executors because of both enough economic power and social status improvement on small sized family. This study indicated that woman outbound travel market gets larger because their buying power and status are going to go improved in Korean social system. It is recommended that marketers be worth watching Korean woman travellers as a major target market through continuos observation and analysis.
