Firms can create additional customer values by changing the visibility characteristic of business transactions. Both visible and invisible transactions can provide distinctive values to the customers. Visible transactions are those that are open to the customer: the customer can see the detailed logic of the transaction and may manipulate specific variables to control the transaction process. Invisible transactions mean that customers have little ability to control the transaction flow and may even be insulated from seeing the transaction. These invisible transactions will be taken care of only by suppliers, and be regarded as a process performed by suppliers. This paper pursues finding out the contingencies of successful transaction visibility change by answering to the following question; "when does increasing(or decreasing) transaction visibility make sense to customers?" This archival case study finds out that transaction visibility change should fit to the need and capabilities of customers. Increasing transaction visibility makes sense when customers need a certain supplier's performance and have a confidence in the capabilities of executing the performance. By the same token, decreasing transaction visibility makes sense when customers have substantial troubles in conducting their current transaction actions or when customers don't feel it necessary to conduct them separately because they can be derived from other action.

To accommodate the rapid growth of e-commerce transactions, non-face-to-face transactions, businesses use a wide variety of payment methods. However, many of these payment mediums are not secure as shown by increases in fraudulent transactions. In this paper, we analyze a particular e-commerce transaction medium, the Safety Transaction Service (STS). This system protects consumers through a wide variety of safeguards: safety settlement systems (escrow), consumer damage compensation insurance, payment guarantee, and secure bank settlement. In contrast to the safeguards, we identify the limitations and concerns with the STS and potential legal and political improvements. The plethora of payment methods limits the consumers ability to distinguish between the secured and unsecured transaction services. Regulation and consumer based verification of transaction services are essential to root out dangerously fraudulent systems. We propose the development of specific standards to these systems, in particular the need for consumer confirmation and clear settlement documentation. Only through the active promotion of scrutiny and improvement to STS will consumers be protected in e-commerce.

A comprehensive electronic trade portal such as the electronic bills of lading, e-negotiations and so on, is developed by the Korea Ministry of Knowledge Economy and International Trade Association and serviced by KTNET. The portal, so called u-TradeHub, formally started to provide its services on 22nd May, 2009. If the shipper issues electronic bills of lading, the negotiating bank examines it through the established e-Nego system. However, the issuing bank overseas cannot examine the electronic bills of lading, because any interactive system does not exist. So, after the e-Nego, the electronic bills of lading gets automatically transformed into the paper-type electronic bills of lading and issuing bank examine paper B/L. In process of examining documents, the beneficiary using electronic means in letter of credit transactions may face some risks such as the corruption to the electronic bill of lading after its issuance by the carrier, the corruption after e-Nego and the corruption after the presentation to the issuing bank. In this paper, we studied the problems on corruptions to occur in the middle of the examination process of the electronic bills of lading and suggestions how to solve them are discussed.

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.

The main theme of this research is a case of e-Business implementation in part manufacturing industry, especially in a PCB manufacturing company. The characteristics of part manufacturing industry are as follows. First, an ERP system runs as a legacy system that is ready to be combined with e-Business system. Secondly, the number of customers is very small. The customers are not many individuals but only a few big electronic enterprises that are strategically affiliated with the part manufacturing company. This means that the e-Business of the part manufacturing industry needs to focus on sharing pertinent information throughout the transactions with the customers, not on data-warehousing or data-mining customers' potential needs or requests. In this paper, we extracted e-Business opportunity domains from a PCB manufacturing company, a typical part manufacturing industry. We are intended to enhance information sharing between customers and the company, and provide functions of transactions necessary in the whole value chain from order to shipment. Implementing the e-Business system on the Web can increase the visibility of customers, and further, the company can be transformed into an extended enterprise where the relationship with the customers becomes very close and interleaved. Also, the Cyber Office functionality of the e-Business system can support the salespersons effectively, so that they can spend more time on customer satisfaction. Such efforts, in the future, can be a basis for active adaptation to the industry transformations such as forming e-community and participating in the marketplace.

It is estimated that electronic commerce facilitates international trade and lower transaction cost and help firms make the best of the opportunities of market access. The comprehensive programs had been implemented to provide better electronic commerce environments by international organizations such as OECD, UNCITRAL, APEC, ICC and etc. Especially, WTO plays the most important role to implement efficient forms and rules on electronic commerce after Doha Ministerial Conference. Member countries recognize the need to conduct the electronic commerce in compliance with the principles and rules of WTO. However, there are many issues to be solved such as the clarifications of concepts and definitions, the possibility of adaptation of technological neutrality in GATS, the imposition of taxation in electronic commerce transactions and the methods of protecting copying as well as trademark. The Implementation of concrete forms and rules of electronic commerce in the WTO will be influential to international trade as the member countries have to adapt them in their transactions. Considering that further discussion will be continued in GATS, we need to analyze the problems and strategies for electronic commerce. As there are not concrete international laws for e-commerce, the existing laws must be revised and changed and each country need to present the enactment direction of e-commerce law to streamline e-commerce and to prevent trading partners from conflicting due to legal problems.

B2B transaction was expected to dominate in the global market and thus many e-marketplaces have been built since 1999 in Korea. However, only a few e-marketplaces are thriving and the future of B2B e-marketplaces except MRO area seem to be uncertain. This paper explores why B2B transactions only in MRO area are rapidly increasing and examines the competing structure and business models of MRO e-marketplace. Business models of MRO e-marketplaces are various among different countries. However, they can be classified as three business models:information portal model, purchasing agent model, open market model. It is not easy to answer which business model is most competitive because each models have their own advantages and functions. Information portal model can be easily applied for the e-marketplace which operates off-line enterprises. Purchasing agent model is favorable to the e-marketplaces which has already obtained buyers and sellers. Open market model is desirable to the e-marketplace which has excess to global market.

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.
