Fraud in e-commerce transaction increased in the last decade especially with the increasing number of online stores and the lockdown that forced more people to pay for services and groceries online using their credit card. Several machine learning methods were proposed to detect fraudulent transaction. Neural networks showed promising results, but it has some few drawbacks that can be overcome using optimization methods. There are two categories of learning optimization methods, first-order methods which utilizes gradient information to construct the next training iteration whereas, and second-order methods which derivatives use Hessian to calculate the iteration based on the optimization trajectory. There also some training refinements procedures that aims to potentially enhance the original accuracy while possibly reduce the model size. This paper investigate the performance of several NN models in detecting fraud in e-commerce transaction. The backpropagation model which is classified as first learning algorithm achieved the best accuracy 96% among all the models.

E-business including e-commerce boosts the competitiveness of corporations remarkably through the creation of new value added, positioning itself as the key to national competitive edge. Thus, advanced nations and international organizations such as WTO and OECD are structuring a positive support system for e-transformation. Korea also has been pushing for activating e-business at the government level since 2000. ECRC(Electronic Commerce Resource Centers) project is an efficient government initiative and inter-agency coordination in implementing e-Business policy for industry. This project has been sponsored by the MOCIE and operated through prime contracts with KIEC. ECRCs provide such services as educational training, technology transfer, consulting and information service related to e-Business for industry. They had given the digital opportunity demanded by industry from 1997 but in these days there are many other new e-business activating projects in Korea. This paper sought to study a strategic reform plan of ECRC.

As growing the electronic commerce there are significant changes in the products/services catalog into the on-line environment. Advertent of e-catalog business opportunity for their own product/services enlarges the market volume and there are diverse methods for the presentation of its product/services. A method for the presentation of product/services features one uses identification and classification system. This study constructs a classification system and database layout for the product/services classification system as a part of e-catalog system. We consider the specific method for the GDAS-based dataset and UNSPSC classification system in the distribution industry.

Thanks to the growth of information technology (IT), e-commerce transactions are rapidly developing. Consumers searched and purchased for products and services through e-commerce transactions and felt excitement and satisfaction through shopping behaviors in online shopping malls. The enlargement of company's marketing efforts and consumer tastes of the uncontrolled consumption for goods and services increased the impulsive purchase in online shopping malls. In diffusing consumers' e-impulse buying, consumers increased in expenditures according to unnecessary purchasing behavior in online shopping malls. However, enterprises increased sales and benefits due to consumers' impulse buying in online shopping malls. Accordingly, in research areas of enterprises and consumers levels, the studies of e-impulse buying will provide significant values for marketers of companies. In this study, we analyzed the relationships among intention to use, trust, and value in online shopping malls. And we also analyzed the moderating effect of e-impulse buying with utilitarian and hedonic value to establish trust in online shopping malls. The result of this study showed that hedonic and utilitarian value should have a positive impact trust and trust should have a positive impact intention to use in the online shopping malls. The e-impulsive buying showed a moderating effect on the relationship between hedonic value and trust in online shopping malls. The e-impulsive buying didn't show, however, a moderating effect on the between utilitarian value and trust in online shopping malls. The results of this study will provide valuable implications for implementing e-commerce strategies.

근래에 전자상거래 규모가 매년 증가함에 따라 전자상거래 과정에서 발생하고 있는 피해 역시 빠르게 증가하고 있으며 피해에 대한 구제도 충분히 이루어지지 못하고 있다. 이터넷 에스크로 서비스는 저자상거래의 안전성을 보장하기 위한 유망한 결제 메커니즘 가운데 하나이다. 특히, RFID 기반의 유통/물류 분야에 있어서 인터넷 에스크로 서비스가 상품인도 정보와 실시간으로 연계될 경우, 그 안정성과 효율성은 크게 향상될 수 있다. 본 연구에서는 RFID 기반 유통/물류 환경 하에서 안전한 전자상거래를 보장하기 위해 EPCglobal 네트워크를 이용한 인터넷 에스크로 서비스 연계 방안을 제시하였다. 제안된 서비스 모델은 구매자와 판매자의 계약 체결과 에스크로 서비스 연계를 위한 금융플랫폼의 형태로 구현되었으며, 금융플랫폼은 EPCglobal 네트워크 및 은행 시스템과 완벽하게 연계되도록 구현되었다. 개발된 EPCglobal 네트워크 기반 에스크로 서비스 시스템은 EPCglobal 네트워크의 실시간 상품정보를 이용함으로써 자금순환기간 단축 및 여신상품 개발을 가능하게 하였으며, 기존 에스크로 서비스의 상품정보부족, 구매결정지연 등의 단점을 극복할 수 있었다.

Globalization of the industry induces the internationalization of any given manufacturing company's supply chain. Development of e-Commerce and Information Technology (IT) changes the logistics structure, making logistics information systems essential. Web-based connectivity and supply chains based on new technologies are becoming essential in the logistics industry. Customers are driving the implementation of systems to ensure timely, thorough, and accurate information, often with immediate access; in response, the Internet has propagated tracking and tracing systems. Value-added services are the key to successful intermediary activities. The nationwide Integrated Logistics Information System (ILIS) aimed to utilize existing and future information infrastructure and knowledge bases to build an integrated logistics information network that would provide comprehensive logistics information services for shippers and carriers in order to improve the efficiency of both inventory and information flows in their supply chains. The ILIS, as one of the seven national information networks, has provided various services, particularly services related to import/export and clearance. Though a survey concerning logistics information services shows rather positive results, shippers and carriers still require better services and reductions in EDI prices. Therefore, the role of the ILIS needs to be re-defined. Short-term plans for the ILIS contain ICD services and XML/EDI services, which are described in detail.
