  • Recently, the number of Internet shopping malls increases dramatically Internet shopping malls offer direct sales by electronic catalogs. As compared with to physical stores and paper catalogs, electronic catalogs differ in terms of the varieties and types of products offered, promotional efforts, service, interface, ordering and delivering, and so on. This paper analysed the features of electronic catalogs for fisheries by 45 variables. By descriptive statistics of electronic catalogs for fisheries, most electron)c catalogs had sufficient product related information. But promotion and transaction security related features were scarce. And some development technologies of electronic catalogs for fisheries were obsolete. By factor analysis, there were 9 factors of electronic catalogs for fisheries, that was, design of product pages, transaction information, playfulness, convenience of product selection, interface design, design of homepages, product information, learning capability, other electronic catalog related factor. Thus in standardizing electronic catalog for fisheries products, the above 9 factors should be reflected significantly.

  • In 3 electrode reflective displays using a plastic substrate, unstable packaging induces particle clumping and optical degradation due to external air inflow and electronic ink evaporation. In this work, we fabricate 3 electrode electronic paper using glass wafer, ITO/plastic film, and ITO/glass/gas barrier film as an upper substrate after injecting electronic ink onto the lower substrate. Then, we studied its properties. After operating under stress conditions for 336 hours at $85^{\circ}C$ and 75% humidity, the reflectivity of driven e-paper panels with white color was 25.5% for the panels using glass wafer, 22.5% for plastic film including a gas barrier layer, and 16% for plastic film only. From these optical properties, we conclude that gas barrier film improves upper film isolation as a desirable packaging method.

  • 전통적인 종이 문서 서류의 관리를 위한 노력과 비용은 지속적으로 증가하고 있으며 이러한 종이 문서들은 보관이 용이하지 않으며 기본적으로 보안에 취약한 약점을 가진다. 따라서 최근에는 종이 문서들을 전자화하여 전자 문서 보관소에 보관하고자하는 연구가 많이 진행되고 있다. 또한 전자 문서 보관소의 경우 최근에는 공인된 기관에서 공인된 제 3자에 의하여 보관되고 제공되는 방법도 제시되고 있다. 전자 문서 보관소의 경우 문서를 전자화하여 보관, 관리하게 되므로 종이 문서를 관리하는 것보다 비용이 적게 소요되는 장점을 가진다. 그러나 이들 전자화된 문서의 보관, 관리를 위한 체계적인 보안 방법이 제시되지 않고 전자 문서 보관소를 소유, 운영하는 기관의 필요에 의하여 보안방법이 제시되고 있어 이들 문서에 대한 체계적인 보안 관리 기법이 필요하다. 본 논문에서는 전자 문서 보관소의 문서 정보 보안을 위한 기본적인 방법들을 연구, 제시하며 이를 통하여 보다 저렴하고 안전한 전자 문서 보안 방법과 보안에 보다 효율적인 전자 문서 보관소의 관리 기법을 제시한다.

  • This paper shows the architecture of IPS(Intermarket Payment System), an implementation of the electronic payment function for internet-shopping merchant system. Because the original purpose of commerce transaction is the exchange of money for goods or services, it is very important to prepare an exchangeable economic value or method. The electronic payment system is the hardware or software or both to process an electronic payment transaction. It has two type, the broker type and the electronic value type. The broker type means an intermediator between real bank network and internet commerce transaction. The electronic value type means a substitute for money in the real world. This paper shows the architecture and the function to implement the broker type electronic payment system. The system has two parts. One is the mediator part to support multiple payment systems and to offer common access methods for merchant system database. The other is the executor part to implement the payment protocol and to process payment transaction.

  • Thesedays more collaboration is required of scholars than before, because some complex problems are beyond the individuals' research capability. Traditional print-based journal systems have been playing a role of supporting scientific collaboration, in that they provide the state-of-the-art knowledge. Those journal systems, however, are known to have some problems. To cope with some of those problems of the print-based journal systems, electronic journal systems have been suggested and implemented. Investigation shows us that electronic journal systems still have some problems. This paper proposes a new form of electronic journal system, structured electronic journal system, which is believed to better support the scientific collaboration. It is designed so that it is easier to figure out the synopsis of an article and so that authors and referees of a submitted paper can participate in the discussion for verifying the significance of the paper. Object-oriented design of a structured electronic journal system which is to be built on top of a object-oriented database system is explained with example structures.

  • In this paper, I examined the trends of standardization and electronization of trade documents and SWIFT network. Also, I reviewed on emerging electronic documentary credit for electronic payment and electronic presentation of documents. New international trade customs and practices are being established and changed as a result of the growth of the Internet and other on-line networks. At the same time there is increasing pressure to move from existing paper-based documentary credit to electronic documentary credit. Several projects devoted to development of an electronic letter of credit infrastructure have recently been proposed such as Bolero, SWIFTNet, UNeDocs and eUCP, etc. Yet, little can be done until the presentation process is electrified between traders and banks. Also, interbank communication of letters of credit has long been electronic, mainly through the SWIFT. However, it is not functioned between applicant and beneficiary, although the solution of SWIFTNet has recently been developed. The Banking Commission of International Chamber of Commerce established a working group consisting of experts in the related fields to prepare the appropriate rules as a Supplement to UCP 500 for Electronic Presentation: eUCP. The eUCP will provide the necessary rules for the presentation of the electronic equivalents of paper documents under letters of credit. Some problems of electronic presentation under the eUCP, exist such as format, presentation of electronic records and the way of beneficiary's notice for completeness under the Article e5 if more than one record is to be presented electronically by third parties. Therefore, it is encouraged to provide more detailed guide for eUCP Article e5.

  • China draws lots of attention from many multinational corporations all over the world as one of the biggest market in the world. Due to the huge territory and explosive population, it is considered that China has endless potentiality. Moreover, since China joined the WTO, China opens its market, developing the policies for opening of its market. Based on the enormous purchasing power, China gets another attention in industry of electronic commerce. With the development and expansion of information technologies, China's electronic commerce has rapidly developed. Since the market of electronic commerce in China is in the developing stage, there is still a big market for electronic commerce and also Chinese government has made much effort in order to develop the industry of electronic commerce. However, in spite of these circumstances, the Chinese electronic commerce industry is far behind the developed countries. There could be many reasons for slow development in industry of electronic commerce and the main purpose of this paper is to discuss these reasons. First of all, the current status of electronic commerce industry in China will be analysed, and then, main problems of electronic commerce industry will be discussed in order to find out the reasons why the industry of electronic commerce cannot develop as much as it is anticipated. It is expected that this paper can contribute to understanding electronic commerce industry in China, and it will be helpful for companies which have a plan to extend their businesses in China.

  • An investigation was conducted to determine whether the ratio of the fluid to the charged particles affects the panel reflexibility rate and the drifting current flowing in the panel, in electrophoretic-based electronic paper. In this regard, three panels were produced in this study with the ratio of the charged particles to the fluid set as 1:5, 1:1, and 5:1. Each sample was driven using an identical input pulse, for which the current flowing in the panel and the output voltage of the photodiode were measured for the panel reflexibility rate. Consequently, the drifting current initially exhibited a peak value and a saturated value at a later point. This value was proportional to the ratio of the charged particles, and it was similar to this ratio when it is higher than 1:1. The output voltage of the photodiode due to the panel reflexibility rate was proportional to the ratio of the charged particles. However, the response speed decreased if the ratio was higher than 1:1. It is expected that the results of this study will contribute to the analysis of the charging of charged particles in electrophoretic-based electronic paper, and the selection of an appropriate concentration.
