This paper represent a method of constructing the improved virtual reality systems. The proposed method be able to decrease the difference between reality and virtual reality. For the future, the proposed improved virtual reality systems are applied to advanced education, for example U-Learning is mixed with virtual reality based on Ubiquitous computing that is important highly information technology(IT) at $21^{th}$ knowledge based on informational society. Also, we respect to The Control system which is embedded in mixed reality.

The experimental side of earth science contains a lot of variables that cannot be controlled in the classroom or in the laboratory. Therefore, as one method to overcome these difficulties, a learning program using 3D Virtual Reality technique has been developed. The program was used with 701 middle school students. The result showed that the program had a very positive effect on inducing interest and motivation through a sense of immersion, and it also showed to be a big help in the improvement of space perception ability.

In the paper, we develop the ‘Navigation Mechanism’ that can present the 3D space and trace the location in the user's viewpoint. Especially, using this mechanism, VRML tools are used to develop the virtual reality space in the internet. These mechanism can effectively represent the 3D virtual reality space and apply the many 3D related parts like architefure, education, entertainment and so on.

In this study, we evaluated the virtual reality model for dental implant surgery and discussed about the method to make the surgical environment for virtual reality with practical patient data. The anatomical model for patient face was fabricated by facial and oral scan data based on CT data. The simulation scenario was composed step by step fashion with Unity3D. From incision and sinus bone graft procedure which is needed to this patient model to implant installation and bone graft was included in this scenario. We used the HMD and leap motion for immersiveness and feeling of real operation. Twenty training doctor was attended this simulation study, and surveyed their satisfactory results by questionnaire. Implant surgery education program was showed the possibilities of educational tool for dental students and training doctors. Virtual reality for surgical education with HMD and leap motion had advantages, in terms of cheap prcie, easy access.

Safety education for crew members is an essential education because it is directly related to life. When ship emergency response training is provided as a hands-on training rather than a sit-down training, the satisfaction of trainees and the educational effect are higher. However, for ship emergency response training to be conducted through practical training, educational conditions such as time and place are insufficient in reality. In recent years, the use of VR technology in education has been in the spotlight. Practicing through virtual reality is an educational method that other educational institutions are also aiming for because it can increase the educational effect regardless of time and place. On the other hand, in order to provide VR-based education, it is essential to develop related technologies and develop contents. In this study, VR-based content development was performed. The development scenario is about navigation and accident response plan, and it was developed for navigation in narrow waterways and limited visibility.

2003년 미국 IT기업인 린덴랩에서 개발한 3D 가상현실 사이트인 세컨드라이프가 최근 인터넷 서비스 시장에서 큰 주목을 받고 있다. 그 까닭으로는 세컨드라이프가 3D 기반 인터넷 기술과 사용자의 서비스 경향을 충실히 담고 있다는 점과 현실과 밀접히 연결되는 부분을 많이 가지고 있어 현실 세계에 미치는 영향력이 점점 증가세에 있다는 것을 들 수 있다. 최근의 우리나라 교육 현장에서는 다양한 ICT활용 교육을 통하여 학교에서 이루어지는 교과 지도와 생활 지도를 온라인으로 확장하고 있으며, 또한 기술의 발달에 힘입어 모바일 교육과 U-Learning과 같은 새로운 교육 방법과 함께 온라인에서 주목받는 우수한 소프트웨어를 학교현장에 도입하려는 노력을 시도하고 있다. 본 연구에서는 Second Life가 머지않아 교실수업과 인터넷수업을 잇는 매개체로 사용될 것이라 보고 세컨드라이프의 국내외 적용사례를 살펴보고 초등교육에서 활용하기 다양한 방안을 제시하고 장단점을 분석한다.

This paper describes the development of an effective celestial learning system using virtual reality technology. Our system support a deep immersion and comfortable navigation by using HMD(Head Mounted Display) and 3 dimensional mouse. We make three dimensional celestial image dynamically with OpenGL and display the rendered image to HMD. Students can feel that they are on the space ship and navigate through the celestial body. During the navigation, students can get the information of each planet and solve given problems. Our system shows that virtual reality can be used as an effective tool for training and education.

최근 가상현실(Virtual Reality)기술이 급격히 발전하고 있다. VR기술의 가장 큰 특징은 몰입감 증대를 통해 가상현실에서 시각적 정보를 구현한다는 것이다. 현재 군사 교육 엔터테인먼트 의료 등 매우 다양한 분야에서 콘텐츠의 개발이 활발하게 이루어지고 있다. 그 중 게임 산업에서 주로 활용도를 높이는 것을 배경으로 하여, 본 논문에서는 VR기술의 발전사로부터 VR구현 장비인 HMD의 기술적 발전방향 연구를 통해서 미래형 HMD디자인의 방향을 고찰하고자 한다. 탐구 이를 기반으로 향호 게임마니아의 니즈에 부합한 HMD 디자인을 제시하고자 한다.

Learning system on virtual environment gives the immersive feeling that lacks in existing E-Learning system, excites user's interest, and offers dangerous and expensive education contents. In this paper, we classified the learning categories into four classes: realtime lecture, anytime study, practice education, and the activity of study group. We built the on-line lecture system using Second Life that supports 3D virtual world and mixed reality. We provided virtual learning environment as running developed virtual world on-line lecture system.

In this study, the effect of VR exposure programs integrated with web-based cognitive restructuring education on reducing social anxiety was confirmed. The experimental group (n=12) received a 10~15 minute session of web-based cognitive intervention and a 20-minute session of virtual reality exposure therapy. The comparison group (n=15) received a 10~15 minute session of web-based speech education and a 20-minute session of virtual reality exposure therapy. After 4 weeks, the experimental group had an increase in positive interpretation bias, a decrease in negative interpretation bias, and a decreased level of social anxiety. These results suggest that the combination of self-help form of web-based cognitive intervention in the treatment of social anxiety disorder can improve the therapeutic effect of VRET.
