This study discusses some theoretical implications for efficient utilization of the global E-commerce in a world of uncertainty by beginning with measures of risk and return for the global E-commerce, and by moving to risk and return for a efficient transaction portfolio of many risky methods of transaction. Decision rules are developed to show how individuals choose optimal transaction portfolios that maximize their expected utility of wealth. First, the individuals will generally want to allocate positive amount to the global E-commerce, which requires that the expected marginal utility of wealth equals zero. Secondly, the optimal transaction portfolio will be determined by finding the point of tangency between the efficient trading line and the hightest indifference curve in the mean-variance plane. Thirdly, if the global E-commerce is positively correlated with wealth, it must have an expected return that is higher than the risk-free transaction methods in order to compensate for its risk. Fourthly, on the other hand, if the global E-commerce is negatively correlated with wealth, it will have an expected return that is less than the risk-free transaction methods. Finally, the valuation of global E-commerce depends on the degree of individual's risk aversion and the covariance between the expected return of total wealth and the return of global E-commerce.

Previous e-financial anomalies analysis and detection technology collects large amounts of electronic financial transaction logs generated from electronic financial business systems into big-data-based storage space. And it detects abnormal transactions in real time using detection rules that analyze transaction pattern profiling of existing customers and various accident transactions. However, deep analysis such as attempts to access e-finance by insiders of financial institutions with large scale of damages and social ripple effects and stealing important information from e-financial users through bypass of internal control environments is not conducted. This paper analyzes the management status of e-financial security programs of financial companies and draws the possibility that they are allies in security control of insiders who exploit vulnerability in management. In order to efficiently respond to this problem, it will present a comprehensive e-financial security management environment linked to insider threat monitoring as well as the existing e-financial transaction detection system.

This paper focused on exploratory testing the organizational management area by examining conceptualized relationships between e-commerce usage type and organizational structure. The research model consists of three e-commerce usage type such as buy-side, internal, sell-side activities and four organizational structure dimensions like decentralization, specialization, formalization, and administration intensity. An interview and an e-mail survey of managers were used to obtain information on the variables relevant to e-commerce activities and organizational structure. The data resulted in response from 58 companies. Major findings of this research are summarized as follows: buyer related e-commerce activities is positively relate to the administrative intensity and the specialization, internal process is positively relate to the formalization, while customer related e-commerce is directly relate to the decentralization and the specialization in terms of organizational management.

정보통신 기술의 발전에 따라 전자 거래를 위한 다양한 기술들이 개발되어 왔다. 그러나 전자 거래에서 사용되는 국제 표준 문서, 국내 표준 문서, 지침서 등과 같은 정보를 체계적으로 관리 및 제공할 수 있는 표준화 된 방법이 개발되어 있지 않다. 따라서 이 논문에서는 전자 거래 관련 정보의 효과적인 관리 및 서비스를 위한 레지스트리 모델을 제안한다. 이를 위하여 관리 모델의 가장 기본적인 정보모델인 ISO/IEC 11179 메타데이터 레지스트리를 참조하여 전자 거래 분야의 표준 참조 시스템 관리 레지스트리 정보 모델을 정의한다. 제안모델은 체계적인 표준 관리 및 상호 연계를 통하여 거래 기업이나 개발 업체에서 전자 거래 시스템 도입 및 구축 시 참조할 종합적인 표준정보 제공을 가능하게 한다.

It is settled in the economic arena that electronic commerce which used the Internet is new recently by explosive increase of the rapid development and Internet use of the information and communication technology. The problem that is legitimate at a point called the business of the form that the electronic transactions to set together if I drift are new of the times is the situation caused a lot. However, the use custom of construction and electronic transactions of the maintenance that is the legislation thief who can do rules of electronic transactions is the fact that it was not able to be still established It may not be just applied to the Internet electronic transactions that an exchange promise between our characters does against unspecified number of the general public person in the property even if I say that the conclusion of the purchase agreement is concluded in Internet electronic transactions by EDI method. That can have the approval of contract in the main legal problem of such an Internet electronic transactions contract. We civil law sorts it by a contract between the talks characters and a contract between the remote area people and all the adopted children are equal and must decide the formation of contract time in a principle of Empfangstheorie because it may be said that the rule of the civil law that it be heated and decides to be able to be available is irrational.

본 연구에서는 전자상거래에서 소비자 구매행위에 영향을 미치는 요인이 무엇인지에 대하여분석을 하였다. 전자상거래는 거래활동의 주체에 따라 기업내 거래, 기업간거래, 기업과 소비자간거래 등으로 분류할 수 있는데, 기업과 소비자간의 전자상거래가 활성화되기 위해서는 먼저 전자상거래에서 소비자의 구매행위에 미치는 영향요인에 관한 분석이 이루어져야 한다. 따라서 본 연구에서는 기업과 소비자간의 전자상거래 관점에서 소비자들이 전자상거래에서 제품이나 서비스 구매시 영향을 미치는 요인들이 무엇인지 설문조사를 통해 얻어진 자료를 토대로 실증분석을 하여 관련성을 검증하였다

This study can be solved a means of authentication of electronic financial transactions. We suggest that smart devices can be useful to authenticate in electronic financial transactions regardless of time and place. Our new authentication method named Lock-Unlock authentication method with smart devices. This method will be expected to reduce many kind of accidents (theft, phishing, hacking, certificates and simple certified OTP, ATM withdrawals, ARS, etc.) by account locking in electronic financial transactions. And helpful to users can effectively protect electronic financial transactions and minimize the accident during get a electronic trading.

In the mold parts industry, customers typically place orders for order-made parts with some changes to the design specifications of ready-made parts within the extent of the manufacturing capability of the supplier. Being customized for ready-made parts, existing e-Catalog systems cannot support the above trade pattern. To solve this problem, an ETO (engineering-to-order) method is proposed here, enabling the trade of order-made parts in an e-Catalog system by utilizing the design and manufacturing knowledge of the part suppliers. After addressing technological challenges and solutions, we briefly describe application of the ETO method to two types of mold parts - ejector pins and mold bases.
