Like traditional commerce, disputes are bound to arise in the course of conducting an e-commerce transaction. At present of June 30, 2001, 259 cases of dispute on e-commerce have been applied for the mediation of Electronic Transaction Dispute Mediation Committee, types of them are 170 cases of delayed delivery of commodity, 21 cases of contract cancellation and refund, 16 cases of personal information protection, 16 cases of false and exaggerated advertisement, 14 cases of commodity defect. The settlement systems of e-commerce dispute are litigation and Alternative Dispute Resolution(ADR). ADR encompasses mediation, arbitration, and similar private tools for resolving disputes. ADR offers many perceived advantages. Speed of resolution and low cost are often cited as the primary benefits. Therfore e-commerce disputes may be settled more effectively by litigation. The settlement systems of e-commerce dispute by ADR are the mediation of Electronic Transaction Dispute Mediation Committee, the mediation of Consumer Dispute Mediation Commercial Arbitration Board, and the arbitration of Korean Commerical Arbitration Board. E-commerce sets up the probability that its merchants and customers will not exist in the same legal jurisdictions. The confusing application of laws and wide geographical dispersion of these parties will necessitate a faster and cheaper dispute resolution methodology. Therefore, online ADR may be effective for e-commerce dispute resolution. The examples of online ADR opetation are the cyber mediation of Electronic Transaction Dispute Resolution Committee, the cyber mediation of Korean Commercial Arbitration Board, the cyber mediation of Click N Settle, the online ADR of BBB online, and the cyber arbitration of virtual Magistrate.

Fiber mats were made at various density levels, using fibers from papermill sludge, ricestraw and various mixtures of the two. The paper mill sludges were collected from Moorim Papermill Co, and Jeonjoo Papermill Co. They were soaked in the liquid sulfur compounds, sulfur-tall oil and sulfurpolyester compounds, and made into fiber-reinforced, sulfur-based composition board. Under optimum conditions of fiber mat preparation and saturation with molten sulfur and modified sulfur, the Young's moduls of the manufactured tiber-reinforced composition board are superior to those of conventional wood-based composition boards. For example, the moduli of elasticity of the composition board made from papermill sludge, with a density of 0.40gm/$cm^3$, were greater than 1,400,000psi as compared 800,000psi for high density hardboard(1.28gm/$cm^3$). The modulus of rupture of the best reinforced composition board manufactured was over 9000psi, comparable to 6000psi of high density hardboard. The proposed Bryant and Lee's theory, "Modified Rule of Mixtures" can be applicable to the nonoriented and short fibrous composition board, when it was modified from "Rule of Mixtures" established by Paul an Jones, and supplemented by Smith and Cox's theory, In the Bryant and Lee's theory of $E_c=\frac{1}{3}aE_fV_f+bE_mV_m$, the constants "a" and "b" for the composition boards made from papermill sludge and the mixtures of ricestraw and the sludge were identified to be in the ranges of 3.29~3.54 and -2.47~-2.80 respectively.

In the past, we implemented a web-based smart education platform, but this is not efficient in a smart or mobile education environment. Therefore, in this paper, we propose an Android-based e-board smart platform for a smart or mobile education system. Here, we use Anoto digital pen- and dot pattern-based technologies. This Android-based smart education platform is efficient for a smart education environment. Further, we implement the hardware and software parts of the technologies, an Anoto-based trajectory recognition algorithm, and a probabilistic neural network for handwritten digit and hand gesture recognition.

This paper proposes e-Learning environments far digital circuit experiment. The e-Learning environments are implemented as a WBT system that includes the circuits monitoring system and the students management system. In the WBT client-server system, the instructor represents the server and students represent clients. The client computers are equipped with a digital circuit training board and connected to the server on the World Wide Web. The training board consists of a Programmable Logic Device (PLD) and measuring instruments. The instructor can reconfigure the PLD with various circuit designs from the server so that students can investigate signals from the training board. The instructor can monitor the progress of the students using Joint Test Action Grouo(JTAG) technology. We implement the WBT system and a courseware fo digital circuits and evaluation the environments.

To improve the efficiency and safety of railway systems, the train control system has been considerably evolved from the ground-equipment-based control system (e.g. track circuit, interlocking system, etc.) into the on-board-equipment-based control system. In addition, this train control system enables the rolling stock to intelligently control the trackside facilities by introducing the information and communication technologies (ICT). Accordingly, since the ICT-based train control system makes the railway system be simplified (i.e. the heavy ground-equipment can be removed), the efficient and cost-effective railway system can be realized. In this paper, we perform the feasibility test of the ICT-based train control system via a simulation. To this end, we have developed the prototypes of the on-board controller and wayside object control units which control the point and crossing gate and performed the integrated operation simulation in a testbed. In this paper, before the field test of the on-board-controller-based train control system, we perform the Consecutive operation test for prototypes of the on-board controller, wayside object control units and local control computer.

The portion of the recycled paper and paper board packaging material has been the highest in recycled municipal solid waste since 1960 but still the portion of the discarded paper and paper board packaging material is the highest (32.3%) in whole discarded municipal solid waste in USA. In order to reduce more the discarded paper and paper board, the common municipal solid waste treatments were compared and recycling treatment was still recommended for the the discarded paper and paper board rather than of the waste treatments, landfill, incineration, and source reduction. In this paper, the obstacled of recycling treatment of the paper and paper board in municipal solid waste and new application of recycled paper and paper board packaging material are discussed.

The main purpose of this study is to statistically analyze the difference between Korea and Japan's consumer attitudes towards e-commerce through the use of auction websites. Here are the results. First, there was a significant difference between the Korean user's attitude and the Japanese user's attitude towards Internet usage; especially, the Japanese user's attitude towards convenience showed a much higher degree than that of the Korean user. Second, Korean users preferred brand image to price, while Japanese users preferred price to brand image. Third, both the Korean users and the Japanese showed a positive relationship between Internet usage and the use of e-commerce. In contrast to the Korean user's frequent use of the bulletin board, Japanese users tended to use the bulletin board less frequently.
