We live now in information society. High-tech communication technique of information came up to our daily life thoroughly. Then, what will happen to change the field of architecture in information society\ulcorner This study realized architecture in virtual reality by choosing technique in virtual reality that was able to alternate architecture in reality. The result of this study: 1. We promoted some shopping malls by making use of 'an active world' that is one of the virtual reality programs. As a result, we could know that we were able to find out goods faster than reality economically and purchase them in virtual reality. 2. There are many fields that we can adapt the architecture in virtual reality beside the shopping malls. For example, they can be a museum, an art gallery, and educational facility, a movie theater, a government and public office, and a recreation facility. 3. The architecture in virtual reality will cause to change our lifestyles and environments and to coexist architecture in reality.

The Fourth Industrial Revolution, centered on intelligence and information, began to take hold in 2016. This study uses virtual reality technology, which is the most popular technology of the Fourth Industrial Revolution. The purpose of this study is to explore a Virtual Walk-through method, which can be easily applied to landscape architecture. At present, virtual reality technology is widely used in the fields of games, emergency training, and architectural design. However, in the field of landscape architecture, it is still in the development stage. In addition, most of the traditional ways to display virtual reality use 2D images, but such methods have some limitations. Therefore, this research addresses the three stages of "design-exhibition-experience" and puts forward a new simple method called 'Virtual Walk-through' that breaks from traditional landscape design exhibitions. The results show that compared with traditional methods, virtual reality has many advantages, such as the freedom of experience, a diversity of viewing angles, information supply, interaction, etc. It can show high quality images and effects, which are suitable for landscape design. It provides an evaluation method for garden design that can be utilized in the future. It is simple and has value as it can reflect the method and the expected effects. Virtual reality technology can bring an infinite number of prospects to the development of landscape architecture.

최근에는 고성능 네트웍으로 구성된 클러스터 상에서 사용자 수준 통신을 사용하는 소프트웨어 분산 공유메모리 시스템의 연구가 활발히 진행되고 있다. 본 논문에서는 사용자수준 프로토콜의 표준인 Virtual Interface Architecture(VIA)를 사용하고 확장성 있는 Home-based Lazy release Consistency(HLRC) 모델을 기반으로 하는 소프트웨어 분산공유메모리 시스템을 구현한다. 본 시스템은 VIA의 원격 메모리 쓰기 기능을 최대한 활용하며, 통신 과정에서 통신 버퍼와 사용자 메모리 사이의 복사가 일어나지 않도록 설계되어 높은 성능을 보인다.

클러스터 컴퓨팅에서 성능 개선의 한계점으로 인식되는 것은 클러스터 내의 통신 서브시스템(communication subsystem)이다. 이러한 한계점을 해결하기 위해서 사용자 수준 통신프로토콜이 제안되었고 Microsoft, Compaq, Intel 3사에 의해서 표준화되었다. 본 논문에서는 사용자 수준 통신의 산업계 표준으로 선정된 Virtual Interface Architecture(VIA)[1]의 개요에 대해서 알아보고, VIA를 효과적으로 구현한 KVIA(Kaist-VIA)에 대해 기술한다.

Many of hotel customers obtain information from hotel websites to find the best alternative. One of the crucial information for the choice is spatial/visual information of hotel rooms. However, hotel website provides photographs only showing representative room features that may not be sufficient to give a full understanding of hotel room to customers. HMD-based 3D virtual environments (HVE) created by 3D camera could improve customers' experiences of hotel rooms by providing full virtual tours of hotel rooms. However, to the best of our knowledge, whether HVE can adequately provide similar customers' perception on spatial/visual information remains unproven as physical hotel rooms. The present study thus aims to verify how similar and reliable information on physical hotel room HVE provides to hotel customers in comparison with hotel website with 2D photograph and display-based 3D virtual environment. For this purpose, this study conducted a comparative experiment to investigate perception of three environments. As a result, the study found that HVE is more effective to provide spatial/visual information as similar as an actual hotel room. In addition, HVE increases customers' perceptions towards the reliability of information, the quality of hotel room and intention to book.

The LVC(Live, Virtual, Constructive) system of CTC(Combat Training Center) is at the very cutting edge of modeling and simulation technology, which has become widely accepted an enabler for a new military training transformation. In this paper, the architecture of LVC system is proposed for the Korean brigade-level CTC, and high level operational architecture, system architecture, and technical standard architecture are suggested.

A VPN is a private network that uses a public network to connect remote sites or users together. As its popularity grows, companies, organization and even the government turned to it as a means of extending their own networks. To setup a Virtual Private a proper IP VPN Architecture must first be selected. In this paper, the types of IP Virtual Private Network Architecture like the MPLS-Based, IPSec-Based and the SSL/TLS-Based are discussed and compared. The comparison may serve as a guide for selecting the proper IP Virtual Private Network Architecture that is suitable for the company's needs.

The purpose of this study was to investigate how student felt the strengths and shortness of presentation methods for formation of interior spaces. For this study, the process of the interior architecture design class was divided into three stages: the programming. the design development, and the design completion. In the design development stage, students used presentation methods: hand sketch, scale model, computer modeling, and virtual realty. The strengths of hand sketch was that quick expression. Models provided three-dimensional feelings. Computer modelling provide realistic color and texture. Virtual reality provided three-dimensional immersion and real scale. It is effective that students collect brain storm images using quick hand sketch in the beginning of design development stage. After that, they compose interior spaces in study models with small scale. Watching the models, they design details of spaces by using hand sketch and computer modelling. Using virtual reality, they can check the scale and circulation. Finally, they complete computer modelling by texture mapping and check the final design in virtual reality.
