EC(Electronic Commerce) which is done on the virtual space through Internet has strong point like independence from time and space. On the contrary, it also has weak point like security problem because anybody can access easily to the system due to open network attribute of Internet, Therefore, we need the solutions that protect the EC security problem for safe and useful EC activity. One of these solutions is the implementation of strong cipher system. YK2(Young Ku King) cipher system proposed in this paper is good solution for the EC security and it overcome the limit of current block cipher system using 128 bits key length for input, output, encryption key and 32 rounds. Moreover, it is designed for the increase of time complexity by adapting more complex design for key scheduling algorithm regarded as one of important element effected to encryption.

물류의 흐름을 배제한 CALS/EC는 있을 수 없다. CALS/EC에서도 거래의 최종단계는 고객이 요구하는 상품 또는 서비스를 전달하는 것이기 때문이다. CALS/EC를 이용한 물류정보화가 물류 문제 해결에 도움을 줄 수 있고, 전자상거래의 활성화를 가로막는 물류 문제를 분석하기 위해 새로운 환경에서의 물류 요구의 변화를 분석하였다. 전자상거래와 물류정보화 활성화와 관련하여, 전자상거래 등 산업활동의 정보화 추이를 고려한 물류체계의 고도화, 산업전반의 물류정보화 촉진을 위한 법 제도의 개선, 물류산업전반의 경쟁력 제고를 위한 규제개혁 추진, 전자상거래 활성화률 위한 통관체제의 개선 등이 필요하다.

The Internet is one of the most noticeable things in the information wave, which is spreading in the whole society. At first, the Internet was mainly used to exchange the information between organizations like universities, institutions and companies, but recently it is widely used as the method for the commerce. Therefore the Internet is recognized as a new strategic tool for the business and electronic commerce(EC) supported by the Internet has become a new type of business in the cyber space. This study is to know the current situation of EC by investigating the effect of the Internet compared with the cost. For this purpose we surveyed 162 Korean companies and analyzed the questionaries collected from them. As a result of the analysis it is shown that the Internet is useful for improving the efficiency of business and advertising the company.

This study investigates the differences in critical dimensions which impact on operations and strategy in Internet EC of service related intangible product. For this purpose, services are newly classified by two selected dimensions such as 1)the proportion of substitute by on-line, and 2)the needs of interaction and customization. Secondly, on the classification of services, the differences of 1) customer needs of geographical accessibility, 2) needs of cooperation with off-line functions, and 3) customer purchase intention in Internet EC are tested among classified groups. Finally, implementations on operations and strategy in Internet EC are suggested, based on the results of analysis. Data are collected by the survey on the customer groups, and analyzed by statistical method, such as mean score plot, cluster analysis, and analysis of variance.

Commerce activities which are free form space and time constraint using a communication network are called Electronic Commerce(EC). Because of sending a commercial information using open network such as Internet in EC, they need the security of commerce information (payment information and purchase information), checking the integrity of transferring data and certifying all parts participated in commerce for a secure commerce. Recently Visa and MasterCard Co. released the Secure Electronic Transaction (SET) Protocol for secure payment card transaction on Internet. This paper proposes a Secure Electronic Commerce Transaction Model(SECTM) using SET in order to support the secure commerce on Internet. The proposed transaction model prevents merchant from abusing the cardholder's payment information (credit-card number etc.) and enables cardholder to shop securely in Electronic Shopping Mall.

Inspired by the growth of the Internet, electronic commerce(EC) has grown rapidly over the last few years and has become a major Internet application domain. EC encompasses various profit-oriented activities such as purchase of goods and services over the network, banking, and business-to-business trade. The purpose of this research is to develop an electronic commerce merchant server for the small and medium size business. The proposed solution is designed to meet a cheap, simple, extensible, and interoperable requirement. Also, our solution supports one-to-one marketing concept by using matching technology. We expect that our solution makes the small and medium size EC market more easily.

This study firstly aims to review the discussions among major nations and international organizations on removal of tariff wall in EC. Secondly, it is analyzed how the trend of tariff reduction of removal will affect an individual economy in a partial balance analysis model on an assumed small-size economy. In closing, political implication for removal of tariffs in EC will be presented. The study concluded that tariff removal on Internet EC has both positive and negative effects on the importing economy. It can improve the efficiency in utilization of economic resources by the importing economy in the long term while cut the financial revenue and aggravate the trade balance of importing country. It is inferred from such a conclusion that tariff removal can lead to trade imbalance between the Information haves and the have-nots.

The tremendous growth of the Internet, particularly World Wide Web, has resulted in significant changes in commerce environments. Internet has brought significant changes in the economics of marketing channels and has led to a redefinition of industry value chain. Electronic Commerce(EC) has become so important that countries and firms unprepared for this new trend would lose competitive advantages in the coming century of Digital Economy. Despite its importance, current EC markets in Korea are immature and there still exist several barriers to EC development thus excluding business to consumer EC markets. As interest in quality management and its effect on competitive performance has grown, there has been a corresponding proliferation of research. However, the majority of the research on quality management has not evolved in a comprehensive and rigorous fashion, particularly with regard to reliability and validity issues. The purpose of this paper investigates on Vitalization of the Activities of on-line shopping mall under of TQM system in Korea. That would make it possible to remove elements of insecurity and doubt currently felt by many users of on-line shopping mall(internet detail or cyber mall) business. In addition, we tried to find out what factors discourage consumers from using electronic purchasing methods, as well as how perceived quality factors and customer satisfaction when consumers are exposed to the purchase process on the on-line shopping mall business.
