In this study, an electronic parts assembly training system using Leap Motion was developed in consideration of the processes actually operated in the assembly process of electronic products. Based on Leap Motion and Oculus VR equipment, the system was developed to transfer user's hand movement data in real time and convert it into hand movement in virtual space so that electronic parts assembly simulation can be performed step by step. Through this, it was confirmed that the user can obtain an experience similar to the actual electronic parts assembly work, prevent errors that may occur during the assembly process, and improve proficiency. It is expected that this thesis will provide directions for the quality improvement and development of various education and training programs for virtual reality-based manufacturing processes.

The purpose of this study is to identify the impact of IT group efficacy of small business using B2B e-commerce on organizational performance. First, we conceptualized IT group efficacy, based on theories in regard to group efficacy, absorptive capacity, and electronic information sharing. And then we examine that IT group efficacy of small business setting up IS and performing B2B e-commerce increases absorptive capacity and electronic information sharing, and ultimately improves organizational performance. The result is that IT group efficacy has a significant positive effect on absorptive capacity, but doesn't have a significant positive effect on electronic information sharing. Also absorptive capacity has a significant positive effect on electronic information sharing and organizational performance, and electronic information sharing has a significant positive effect on organizational performance. Finally, we discuss about the limits and directions as well as the results and implications of this study.

The electronic wedge brake is one of the brake-by-wire systems with a self-energizing effect. The electronic wedge brake has faster response than the conventional hydraulic brake and requires only about one-tenth the power to operate. However, the electronic wedge brake cannot be implemented unless the self-energizing effect is reliably controlled. The self-energizing mechanisms may result in unintentional lock up and are very sensitive to environment and parametric variations of the friction coefficient. In this study, the electronic wedge brake is modeled into dynamic equations, and a sliding mode controller is designed based on the model. The performance of the proposed controller is verified in simulations.

In this paper, we investigated the island density-dependent stress distribution of indium-tin-oxide (ITO) film on polycarbonate substrate by external bending force. We used e-beam and RF­sputter for SiON, ITO sputtering. It was found that there are influence of island density on the substrate and decreasing crack density as goes to the minimum density. From the result that crack density was increasing at maximum island density, it is evident that more stress is imposed on same island position as island density.

The purpose of this study analyzes laying stress on Japan example that background of electronic issue of international meritime insurance policy is what, and is marched in some degree present. and this study presented what hereafter subject of electronic insurance plice is. The this paper is to study the current situations of trade financial EDI in Japan and problems in application of marine insurance contracts. The subject of electronic marine policy issue is as following in trade financing EDI. (1) application of electronic document in claim demand. (2) standardization of various documents and insurance plice data. (3) insurance compensation document that become Jeonjahwa in insurance accident settlement. (4) maritime Insurance policy agreement's establishment. (5) when is monopolized to third party, realization of electronic maritime insurance policy offer.

The GUIDEC I was published in November 1997 by the International Chamber of Commerce (ICC) and then the GUIDEC was published in October 2000 in the name of GUIDEC II. The GUIDEC II is the next version of GUIDEC I. This paper examines the electronic authentication and certification practices under GUIDEC II in detail. Therefore, this paper can help parties concerned to understand electronic authentication and certification practices of electronic commerce. GUIDEC II maintains the content of GUIDEC I, but GUIDEC II adds some new definitions such as authenticating a message and explains the rights and responsibility of subscribers, certifiers, and relying parties in detail. The aim of the GUIDEC II is to enhance the ability of international business community to execute trustworthy digital transactions utilizing legal principles that promote reliable digital authentication and certification practice.

Metal halide lamps have been made suitable for use in outdoor illumination systems over many years. They are also widely used in application and commercial lighting due to their attracting properties such as good quality color, rendering and high efficiency. Over the past few years, a considerable number of studies have been conducted on the electronic ballast with hot restarting and resonance phenomenon. However, very few attempts have been made at the adaptive ignition method according to lamp state. This paper proposes an electronic ballast for metal halide lamps with an igniter for adaptive ignition. The proposed electronic ballast can generate different ignition voltages according to the arc tube state. The experimental results showed that the proposed ballast circuit using adaptive igniter is suitable for 70W HQI lamps.

The purpose of this paper is to analysis the legal aspects of e-commerce, particularly those relate to electronic contract, in China On 23 November 2005, the United Nations General Assembly adopted a Convention on the Use of Electronic Communications in International Contracts, known popularly as the Electronic Communications Convention. China signed it but the convention is not binding yet as it still requires the ratification by three states. On the other hand, China adopted a new act legalizing the electronic signature in 2004. This new act provides electronic signatures with the same legal status as handwritten signatures. But the efficiencies that business hopes to achieve through electronic commerce are not completely reflected in the legal processes necessary to support those hopes.

This article discusses the critical issues on obligations and responsibilities in electronic funds transfer(EFT) between Article 4A of the UCC and the Model Law on International Credit Transfers of UNCITRAL. The electronic fund transfers begin with the issue of the payment order by the originator to the receiving bank for the beneficiary. All obligations and responsibilities of parties concerned occur when the receiving bank accept the originator's payment order to executes. So far, some the most compelling studies have focused on the legal obligations and responsibilities of electronic fund transfer in Korea. Therefore, In this paper, we would like to examine some problems of obligations and responsibilities in electronic fund transfer from Article 4A of UCC and the Model Law on International Credit Transfers of UNCITRAL. And also we present some Implications to reform EFT Law for the efficient application.

The goal of this study was to examine differences between traditional and electronic commerce in criteria of the amount of consumer information and the level of consumer satisfaction. In addition this study examined factors influencing the amounts of information search of consumers and the level of consumer satisfaction between traditional and electronic commerce. The results of this study are as follows. First, consumers gathered more information about stores and price in electronic commerce, but more information about quality and after service in traditional commerce. Second, overall, rational consumers, and consumers buying electronic goods collected more information. Third, consumers were more satisfied with shopping in electronic commerce than in traditional commerce except for the satisfaction from price. However, comsumers' satisfaction was not differed what kind of goods consumers buy. Fourth, if consumers gathered lots of information, they tend to be more satisfied than otherwise. In addition, there were positive relationship between consumer’lower age, rational purchase behavior, and positive thinking of the electronic commerce.
