Today's Virtual Reality(VR) technology has become considerably more affordable and sophisticated with rapidly advancing computer technology. Photo-realistic visual representations along with real-time interactivity are now achievable without special programing knowledge and expensive equipment. The purpose of this paper is to establish how simple, credible user testing methods based on VR simulations can be utilized to improve design decision making towards more sensible design solutions for end-users. Results of a case study demonstrate the value of potential user-testing feedback in a simulated 3D virtual service space, i.e., restaurant interior. User feedback from the VR simulation includes preferences in table location, privacy, and values of seating preferred tables. A new design framework incorporating an empirical testing method for service spaces is presented. The overall design process, the development of the VE, and the user testing method and findings are discussed. This study provides useful guidances for future efforts in the areas where such technology may benefit to understand end-user feedbacks in design process.

효과적인 백신 프로그램을 디자인하기 위해서는 질병과 면역에 대한 기본적인 이해가 필수적이다. 면역에 대해서 이해하기 위해서는 크게 체액성 면역과 세포성 면역으로 구분하여 이해하는 것이 유용할 수 있으며, 또한 이 두 가지 기전은 서로 상호협동적으로 작용한다는 사실을 이해하여야 한다. 숙주동물(닭)이 병원체이든 백신이든 일단 항원에 한 번 노출이 되면 이를 기억하는 기억 세포를 생성하여 두 번째 노출되었을 때 폭발적인 면역반응이 일어나도록 한다. 순환항체가 형성이 되면, 이 항체는 난황을 통하여 후대 병아리에게 전달될 수 있다. 면역의 형성은 백신이 가진 항원의 특성과 백신의 타입(생독, 사독)에 따라 다른 방식으로 나타난다. 면역에 대한 기본적인 개념을 충분히 숙지하고 다음의 사항을 고려하면 효과적인 백신 프로그램을 선택하기가 용이하다. (1) 전례 : 어떤 프로그램이 효과적이었는가? (2) 질병 : 어떤 질병이 문제가 되고 있는가? (3) 균주 : 균주의 차이는 중요한가? (4) 관리 : 백신의 사용을 불필요하게 할 효과적인 사양관리가 이루어질 수 있는가? (5) 모체이행항체 : 모체이행항체가 적절한 방어력을 가질 수 있을까? (6) 면역증강효과 : 그 중요성과 접종시기가 숙지되어 있는가? (7) 접종기술 : 접종기술에 문제가 있는데 프로그램이 제대로 효과를 발휘할 수 있을까?

Fast long-distance network 에서 기존 TCP 의 혼잡 제어 (congestion control) 알고리즘은 대역폭을 효과적 사용하지 못하는 문제점을 가지고 있다. 대역폭을 효과적으로 사용하기 위해서 TCP 혼잡 제어를 수정한 다양한 프로토콜들이 제안되었다. 이러한 프로토콜들은 디자인 시 주로 bandwidth scalability, TCP friendliness, 그리고 RTT fairness 와 같은 세 가지의 특성을 고려하고 있다. 하지만 제안된 프로토콜들은 어떤 것도 trade-off 관계로 있는 이 세 가지 특성을 동시에 만족시키지 못한다. 본 논문에서는 혼잡 제어 알고리즘의 증가 규칙 (increase rule)에 RTT 를 직접 반영함으로써 위 세가지 요구사항을 동시에 만족시키는 EIMD (Exponential Increase/ Multiplicative Decrease)라고 하는 새로운 TCP 혼잡 제어 알고리즘을 제안한다. EIMD 는 패킷 손실이 없는 한, 지수적으로 윈도우를 증가시켜 효과적으로 대역폭을 사용하면서도, 패킷손실 직전의 윈도우 크기, $W_{max}$ 에 반비례하게 윈도우를 증가시킴으로써 fair share 에 빠르게 수렴할 수 있다는 특성을 갖는다. 모의실험을 통해 제안된 프로토콜이 fast long-distance network 에서 위 4 가지 특성들을 모두 만족하는지 검증한다

Wireless Body Area Networks (WBAN) have been made possible by the emergence of small and lightweight wireless systems such as Bluetooth, enabled devices and PDAs. Antennas are an essential part of any WBAN system and due to various technical requirements and physical constraints, careful consideration of their design and deployment is needed. This paper is proposing on the design of wearable antenna as parts of clothing to serve communications functions, such as tracking and navigation in health care applications. The substrates of the wearable antennas will be made from textile materials and since it is wearable, it should have a small size, be light weight, low maintenance, and unobtrusive. This proposed paper will also investigate the influence of different parameters for wearable antenna including types of textile/substrate to ensure that the antenna design satisfies WBAN requirements. The characteristics and behavior of the antenna need to adhere to specifications set by wireless standards and system technology requirements. This means that the transmitting and receiving frequency bands of the various units need to be chosen accordingly. Since there are restrictions on the level of power to which the human body can be exposed to, the antenna as well as other RF system components must be designed to meet these restrictions. Antenna gain, which directly affects power transmitted, is a critical parameter in ensuring power levels fall within the safety guidelines and so will be of primary importance in the design. The electromagnetic interaction between WBAN antennas and devices and the human body will also be explored.

As life gets richer along with social development, the interest in composure of life and in quality of life gets higher. According to this, a concept on bathroom, which had been simply physiological sanitary space before, is being gradually changed, thereby being reborn as space of charging vitality of life and of realizing own desire. As these consumers' new desire is emerged, it is being highlighted the behavior of being made in space now called 'bathroom', the requirements for this space, and the interest in what aims to be pursued. However, current Korean people have different bathroom behavior such as using outside bathtub or filling a washbasin with water unlike the center on stand-up shower in the West, thereby having inconvenience. Accordingly, when bathroom is designed that reflects Korean people's bathroom behavior, the satisfaction with using bathroom will be able to be enhanced. This study aims to increase the use satisfaction with bathroom space, to survey Korean people's situations of using bathroom, the inconvenience in using, and the general emotion, and to elicit requirements for bathroom users and basic design guidelines available for reflecting the health in planning bathroom space, the space of solving sanitary problem, and the modern people's physical features and lifestyle.

As our country holds 2002 Korea-Japan FIFA World Cup, more foreigners are visiting Korea, making the tourist industry more profitable. Under these circumstances, we should pay attention to the restroom as a public facility, and inspire the awareness in the Korean people to improve the public restrooms. However, according to KNTO(Korea National Tourist Organization), it has turned out that foreign tourists are still dissatisfied with dirty restrooms and poor signposting when they visit Korea, Though the number of restrooms has been increased, they are not properly managed being a public nuisance due to negligence of administration and straggling facilities. To make it worse, poor design of restrooms and insufficient consideration of handicapped person bring disgrace on Koreas tourist administration. While studies on restrooms began from the 1980s, it has placed too much emphasis on the space arrangement and facility plan, so we need to pay attention to the traditional design and environment aspect of restrooms. This study is 1 haute looked into the problems and actual conditions of restrooms, and based on these data, applied Korean Buddhist architecture style to restrooms to create a comfortable circumstance in restrooms.
