This paper proposes the design and implementation of a system to provide a web-based ubiquitous 3D virtual reality education environment for secondary students to help experiment freely with safety by computer simulation in physics education. To realize this system, ThreeJS, one of the famous 3D graphics libraries based on javascript, has been used to support WebGL(Web Graphic Library). Hence the system became browser independent to give flexibility for most users. It is designed to make the mouse control change the position of the camera of the 3D graphics, so that the user can observe the virtual motion in various viewpoints. In contrast to the other local PC based education systems, this web-based system is much easier for distribution and management.

정보기술의 발전과 인터넷의 발전으로 E-러닝 시스템은 누군가의 도움 없이 혼자 공부하는 법을 가르친다. 사람들은 자신이 가지 고 있는 능력을 향상시키기 위하여 원하는 교육을 E-러닝 시스템을 통 하여 어디에서나 교육을 받을 수 있다. 교육을 받는 사람들은 능력이 증대되며, 자신감은 기업을 더욱 효율적으로 변하게 한다. 본 논문에서 는 E-러닝 시스템을 모듈별 설계원칙을 제시하고 구현 하였다. 많은 사람들이 E-러닝 시스템을 이용할시 시스템의 안정성과 프로그 램의 보안성이 중요시 된다. 따라서 클러스터링에 의한 교육의 안정적 운영을 제시하였다. 또한 EJB3.0을 이용하여 보안성을 강화 시켰다. 모바일 프로그램의 개발 방법인 앱웹 방식과 비즈니스 로직 부분을 EJB3.0을 활용하여 클러스터링 환경 구축으로 모바일 시스템 서비스의 안정성과 보안성을 강화 하였다. 따라서 E-러닝 시스템의 설계방법과 구현은 타 시스템의 설계에 참고 자료로 활용될 수 있다.

The international and domestic revenue keep growing constantly, and nowadays the international casino game industry is getting upgraded utilizing IT technology. In contrast, due to many constraints and limitations, Korean IT society has not paid attention to the casino IT area. Slot machine is one of popular gaming systems in the casino. In this paper, we present our design and implementation of protocol analysis system for SAS 6.0 protocol. Slot machine accounting system (SAS) is an international standards protocol and provides auditing, management, and additional service for slot machines. Our protocol analysis system design experience provide in-depth understanding on slot machine and its accounting requirement than a simple conceptual introduction of protocol. Also, the key difficulties of SAS protocol implementation and performance requirement is examined. Our system successfully works in small portable embedded system and showed its benefits, showing benefits for debugging and reverse-engineer a real work problem with commercial system. The engine of the analysis software will be the base of real SMIB (slot machine interface board) system for commercial use.

This paper aims to design and realize movie reservation system based EJB 3.1 with Enterprise of Standardization. This architecture, such as the EJB, but not heavy, to provide all of the architecture is possible. The lightweight container architecture is most often used in business EJB 3.1 is well-known architecture. Therefore, this research has the N-tier enterprise architecture to solve the advantages and disadvantages developed to support the latest EJB 3.1 architecture based on the design and implementation of a movie reservation system.

The implementation system of the recommendations and rulings of the Dispute Settlement Body is an important component of the WTO dispute settlement procedure. Where there is any disagreement between disputing parties as to the existence or consistency with a covered agreement of measures taken to comply with the recommendations and rulings, a winning party may refer the matter to a compliance panel and the Appellate Body. If a losing party is found to have failed to comply with the recommendations and rulings, DSB may authorize the winning party to retaliate. This article analyzes the implementation system of the WTO dispute settlement procedure in comparison with other systems of ‘second-order’ compliance in international law. Also, attention will be directed to the relationship between the WTO retaliation and countermeasures in general international law. Countermeasures under the Agreement on Subsidies and Countervailing Measures, in particular, have a legal nature akin to that of countermeasures under the law of State responsibility.

In the current Internet environment, a lot of multimedia information is used; such as text, sound, image, and video. Among those information video is the most valuable and meaningful data. Therefore, the key frames of a video are very important role to recognize the whole sequence contents. In this paper, we propose a new key frame extraction scheme using chi-square and color histogram. The proposed key frame extraction scheme showed the better results compared to the previous studies. The proposed scheme results will be applied to the many computer game programs for the fast scene detection and the recognition of the game contents.

The objective of this research is to analyze the effect of quality management system constructed by ISO 9001 certificates through BSC perspectives. Evaluation of quality management system based on BSC framework can consider short-term financial performance as well as nonfinancial performance characteristics, which will derive future financial results. This results show that QMS has an indirect effect on business performance through quality performance and customer satisfaction, which are internal business process and customer perspective, rather than has a direct effect on financial performance. Finally we suggest implications of this study and future research direction.

일반적으로 물리 교육에서 실험 활동을 통해 학습자들은 일상생활 중 경험과 밀접하게 연관된 힘과 운동 분야의 개념을 보다 확실하게 이해할 수 있다. 하지만 현재의 교육 실정에서는 실험 수행시간 부족 등의 열악한 환경으로 충분한 실험 활동을 하지 못하고 있다. 이를 보충하기 위해 정지성 등[1]은 모션센서 컨트롤러를 이용한 3D 물리교육 시뮬레이션 시스템을 개발하였다. 본 논문에서는 이 시스템에 학습자가 실험의 몰입도를 높이기 위해 3D 가상 실험 공간을 양안식 입체로 가시화하는 색상 방식의 양안식 3D 동역학 교육용 시스템을 제시한다. 학습자들은 제안한 색상 방식의 양안식 3D 입체 영상을 통해 보다 현실감 있는 동역학 시뮬레이션을 수행할 수 있었다.

A system has been developed to reduce fluctuation of the indoor temperature in a radiant floor heating system. The system we developed and implemented is called BoilerMan. With the BoilerMan system the hot water circulation pump is controlled by computer software which implements a unique strategy. To minimize the system development time a user-friendly development environment was used. This development environment was useful in the implementation and testing of the efficiency of our strategy. The environment also serves as an easy means for system maintenance. The BoilerMan went through a few test runs against a real apartment house and the result showed significant reductions in the initial temperature overshoots against the target values. It also reduced the operatingtime of the hot water circulation pump. Such positive results were possible due to our unique strategy that exploits heating efficiency information collected from the past run of the very same system. Since the strategy was implemented with embedded software, it makes the BoilerMan flexible, too.

Therefore, it would be the one system between complicated systems through application integration, it would be also make shop floors visualized. This research would help users and service suppliers getting more advantages of e-Business system.

In this paper, the uAPSS(u-APartment Service System) that is based on location-aware technology is designed and implemented for a luxury apartment. On the real luxury apartment the developed system has been employed and tested to provide convenient and secure living for residents. It provides services such as emergency call, intelligent elevator operation, and hands-free door access based on the location of the residents with personal device as called smart tag. It can also be applied to other service areas such as the location-aware u-Service for hospitals, high-rising complex buildings, silver towns, etc.

일반적으로 물리 교육에서 실험 활동을 통해 학습자들은 일상생활 중 경험과 밀접하게 연관된 힘과 운동 분야의 개념을 보다 확실하게 이해할 수 있다. 하지만 현재의 교육 실정에서는 실험 수행시간 부족 등의 열악한 환경으로 충 분한 실험 활동을 하지 못하고 있다. 본 논문에서는 3D 가상공간에서 모션센서 컨트롤러를 이용하여 실제와 같은 물 체의 움직임을 통해 속도, 힘의 크기, 방향등의 물리 교육에서의 기초 동역학 개념을 보다 쉽게 이해할 수 있는 교육 용 게임 시스템을 제안한다. 제안된 시스템은 학습자에게 그들 스스로 다양한 학습 활동을 시뮬레이션할 수 있는 기 능을 제공한다.

본 논문에서는 질의어를 이용하여 온라인 인터넷상의 게임 보안 시스템과 연동되는 질의어를 암호화할 수 있는 모델을 설계하고 구현하였다. 인터넷과 게임 인증 보안의 연동을 통해 기존의 클라이언트/서버 컴퓨팅 보안 환경을 개선하려 하고 있으며 내부 서버와 연동되는 인터넷게임의 보안이 중요한 문제점으로 떠오르고 있다. 이에 인터넷 게임에 접속할 때 일반적으로 사용되는 인증수단을 개선하여 인증보안이 강화된 ID와 패스워드를 통하여 암호화할 수 있는 암호화 질의어를 생성하고 그 알고리즘을 통하여 데이터베이스 테이블의 정보를 암호화하는 모델을 본 논문에서 제시하고 유지,보수 관리 방안도 함께 고찰한다.
