There are multiple reasons that caused the present serious status of network security, including Internet itself having a weak basis. However security is usually discarded when it contends with performance. As the world becomes more tightly interconnected, security technology continues to mature, organizations are feeling a greater need to rediscover network security. Network security technology generally concentrates on protection of the network infrastructure and, by implication, the protection of the user. This is a paper, describe current problems of network security and propose solutions.

In this study, the factors affecting reality aspect of virtual reality system were identified through Quality Function Deployment. The influence of some selected factors was evaluated in simulated performance test. It was shown that the factor of whether user can break through the objects in virtual space is the most sensitive to performance, followed by the factors of rotation angle and movement step. Also, the results implied that as more referents were provided to user, feeling of reality was enhanced.

An Parallax-Barrier type autostereoscopic display system is implemented to overcome the handicap of current glass-typed stereo imaging system which gives operators unnatural feeling and reluctance. This system is composed of image mixing part of two input images, A/D transformation part, scan conversion part to eliminate the rainbow interference phenomenon, and pin-hole type barrier lens. For the fine display the accurate slit width of barrier is calculated in consideration of retina size, and the samsung 10.4" TFT-LCO was used as flat display monitor.itor.

Artificial muscle actuators are used in various fields. Especially, they are applied to the power assist circuit to make use of their characteristics. The purpose of this paper is to and analyze the power assist circuit using an artificial muscle actuator. As a result, it is found that the operating feeling of the power assist circuit depends mainly on the flow gain of the pneumatic servo valve. The required flow gain is calculated from the proposed model, and the experimental results agreed with the calculated results.

The purpose of this study is to understand spatial composition techniques and character on the tendency of Deconstructivisim in interior design. Interior space is basically surrounded by architectural surface and influenced by architectural shape. Therefore, the main point of this study is based on the inter relationship of interior design and the trend of contemporary architectural design. This viewpoint is to comment upon current events in Korean situation some degree, but allow the new feeling to interior design and can be enlarge the concepts of spatial composition.

기존 증강현실과 같은 합성 추적기법에서, 시점을 확장시켜 깊이감을 얻을 수 있는 다시점 영상기술을 적용하였을 경우 특징추출 및 대응의 연산량은 급격히 증가하며, 넓어진 FOV(field-of-view)는 대응을 어렵게 하여 특징의 흔들림을 초래하고 광원과 가려진 영역의 영향을 증대시켜 시점간의 추적을 어렵게 한다. 이에 본 논문은 등극선 기하조건을 고려한 다시점 실감 영상 합성 추적 기법을 제안한다.

The certification of software products can provide a greater level of acceptance and feeling of security to customers of these products. This paper presents a certification method for the quality of package software. First of all, the evaluation criteria are derived from ISO/1EC 9126 and 12119 standards, and then the evaluation module are designed considering the measurement scale type. The results can be applied to construct the certification scheme of software product quality for the commercial purpose.

Recently computer graphic technology has achieved remarkable development. Applications of this technology to various fields are expected. In this study, one application of computer graphics to the medical field is shown. We developed a rehabilitation system of hand manipulation using virtual reality aiming to offer enjoyable rehabilitation training to physically handicapped people with upper limb disabilities. This rehabilitation system generates training environments for upper limbs, such as moving balls in virtual space of computer. And by using data glove as a sophisticated input device, a user can manipulate objects in virtual space by his hand. By using this rehabilitation system, a user can have rehabilitation training under various conditions without feeling tedious.
