The purpose of this study is to prove asymmetric Consumer Information on Electronic Commerce. For this purpose, 93 internet shopping-malls was analyzed into three contents of consumer information. Major findings are as follows : First, the overall level of consumer information contents through purchase process was very low. The reason is that most electronic consumers were dissatisfied with consumer information provided by internet shoppingmall. Second, consumer information of purchase-stage was insufficient for electronic consumer. Especially most shoppingmalls did not provide Use-information and comparing information. This implies electronic consumer can't meet their consumer information needs, so they cannot make rational decision. Third, consumers were faced with asymmetric Consumer Information problem on electronic commerce. So consumer education for electronic commerce is needed.

As the electronic market grows, the vendors establish internet shopping mall with a plenty of electronic catalogs and prepare to respond rapid electronic market growth. Consequently, building attractable electronic catalogs is very important to give a customer satisfaction. Based on prior researches, this study suggest a research model to understand the factors of electronic catalogs and their impact on the customer's relationship quality. As a result, this study confirmed that accuracy, timeliness, interaction, presentation, and information structure of electronic catalog were important factors. Presentation is the most important factors of electronic catalog. Information structure and accuracy also heavily impact on user satisfaction. And their impact on the customer satisfaction and trust were proved to be substantial. These results will contribute to provide implicit guidelines to the developers of internet shopping malls.

This study suggests that the model of electronic document delivery service be carried out by academic libraries step by step, based on the analysis of the domestic and foreign status. The model consists of the user's request step, electronic document building step, electronic document transferring step. Academic libraries should perform the electronic document delivery service step by step that satisfies user's information need.

The purpose of this paper is to determine success factors important to electronic payment system and also to review its environments in order to present development direction of electronic commerce in Korea. A field survey including interviews and questionnaire surveys is made in 12 experts who were identified as having research experiences and/or development experiences of electronic payment systems, 35 merchants who are doing business over the Internet, and 96 netizens who were identified as a consumer group. In this study, we reviewed four dimensions affecting the acceptance of electronic payment systems such as safety, security, convenience, and efficiency. Finally, we suggested a total of 32 factors important to electronic payment systems and classified all factors into four dimensions.

Appropriate strategies are needed to ensure long-term preservation of various types of electronic records. For proper preservation of electronic records, it is necessary of decision-making processes for risk assessment, notification and implementation of conservation measures. To do this, the task of assessing various risk factors that impede the long-term preservation and utilization of electronic records should be done first. In this study, since electronic records are mostly stored in file form, risk assessment for electronic records of file type is performed. The risk factors required for the risk assessment of the file format are derived, and the algorithms are developed to devise a calculation method of the weighting factor and the risk factor index for evaluating the risk based on the proposed risk factors. In addition, the proposed methods are applied to the file formats used in Korea and risk assessment is performed and the results are analyzed.

High-power devices, such as LEDs and radars, inevitably generate a large amount of heat, which is the main cause of shortening lifespan, deterioration in performance, and failure of electronic devices. The embedded IC process can be a solution; however, when applied to large-area substrates (larger than 8 in), there is a limit owing to the difficulty in the process after wafer thinning. In this study, an 8-in wafer-level high-power electronic package based on the embedded IC process was implemented with temporary bonding and debonding technology using double-sided thermal release tape. Good heat-dissipation characteristics were demonstrated both theoretically and experimentally. These findings will advance the commercialization of high-power electronic packaging.

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.

In this paper, we investigated the device performance on fluorine implantation, hot carrier reliability and RTS (random telegraph signal) noise characteristics of NMOSFETs. The capacitance of the fluorine implanted NMOSFET decreased due to the increase of the gate oxide thickness. RTS noise characteristics of the fluorine implated NMOSFET was improved approximately by 46% due to the decrease of trap density at Si/$SiO_2$ interface. The improved gate oxide quality also results in the longer hot carrier life time.

This paper is to analyzes the recent discussions in the WTO and to draw some basic policy implications for Korea concerning electronic commerce. To foster electronic transactions. the WTO agreement should establish a basic legal framework for international transactions to guarantee a stable and predictable environment. The member countries in the WTO, however, have not formed a consensus on the definition, classification, technological neutrality, and domestic regulations dealing with electronic commerce. Digital transfer and classifications of electronic transfer are the most difficult problems to be solved. The discussions on electronic commerce which had been on hold after the Seattle Ministerial is due to begin in a special working group of specialists. Electronic transactions in Korea have been increased rapidly and the implementation of concrete forms and rules of electronic commerce in the WTO will be influential to international trade as we to adopt them in the transactions. Therefore, we have to open our eyes to the trends of international discussions on this matter and to make our rules and laws of electronic commerce to the international levels.

As information technology has developed, the function of a library has been expanding gradually. The traditional library has changed into the electronic library so that users can directly access the library from remote sites and get electronic information without visiting the library. The purpose of this study is to build a model on the basis of the elements that are identified from the existing electronic libraries, and then to survey the current state of electronization in Korean university libraries. The electronic library model consists of four elements : OPAC, commercial online databases, CD-ROM databases, electronic books and journals, access to OPACs of other libraries, and access to other information resources through Internet.
