A research to evaluate efficiency of design optimization was performed for aerodynamic design optimization problem in distributed computing environment. The aerodynamic analyses which take most of computational work during design optimization were divided into several jobs and allocated to associated PC clients through network. This is not a parallel process based on domain decomposition rather than a simultaneous distributed-analyses process using network-distributed computers. GBOM(gradient-based optimization method), SAO(Sequential Approximate Optimization) and RSM(Response Surface Method) were implemented to perform design optimization of transonic airfoil and to evaluate their efficiencies. One dimensional minimization followed by direction search involved in the GBOM was found an obstacle against improving efficiency of the design process in distributed computing environment. The SAO was found quite suitable for the distributed computing environment even it has a handicap of local search. The RSM is apparently the fittest for distributed computing environment, but additional trial and error works needed to enhance the reliability of the approximation model are annoying and time-consuming so that they often impair the automatic capability of design optimization and also deteriorate efficiency from the practical point of view.

Despite a lot of efforts, school violence is getting severe nowadays and especially it seems remarkably occurring among middle school students. Many studies show that most school violence occur in classrooms where the students spend most of their time in studying and socializing for their everyday life. The purpose of this study is to identify design elements of middle school classroom and to suggest some design plans for preventing school violence, in the point of view of CPTED. For this objective, six middle schools were selected from Gangseo-gu, Seoul, and the questionnaire and survey were conducted to identify the status of school violence and the physical classroom environment in each schools. An analysis was carried using SPSS to identify the correlation between the school violence and the physical environmental design elements. The results are as follows : although each selected school shows different status of school violence and the physical environment in classrooms, commonly the occurrence and the fear of violence are related to the classroom environment. Therefore, In order to plan classroom for preventing school violence, 'the proper size of classroom avoiding overcrowd', 'elevation design for the sense of belonging and territoriality', 'improvement of deteriorated environment' should be considered for reduce the causes of violence. And 'maximization of natural surveillance from hallway', 'accessibility of teacher' should be considered for rapid management of violence.

The growth in human has a close relationship with circumstances and there are two different types of form as a method. One of them Is a great influence of which the environment has a certain effect to human and that is called environmental effect. The other one Is a great reaction of human against the environment which is environmental experience. Human's being loved nature and conservation of nature as a living condition have already processed out for a long time. However, in these days, it is different that a special emphasis on the conservation of nature is being destroyed and it Is perceived the principal of the destruction is human itself. The Museum of Natural Environment has no doubt in a relation with conservation of nature. The main subject of this thesis Is to restore the disappearing beauty in natural environment, an importance of resources in general needs and a change in futuristic perceptions against preservation of the species. Therefore, to produce a complexity in a combination with education and entertainment to a water resource as a main theme is now relieved from its original deteriorated public information center with its simpleness. It Is purposed to secure a cultural space for a community activity and regional peculiarities, dams and lakes, localities of rivers as a main theme to specify their details, to maximize its educational space furtherance with a value as a tourist resource in particular.

It is important that ubiquitous technology changes paradigm of thought, not simple definition in the 21st digital era. Characteristics of ubiquitous computing are pervasive, disappearing, invisible, calm through environment. As IT Technology develops, designers, computer scientists, chemists, performance artists cooperate in order to find out the best way to make desirable digital clothing in the future, with the merit of each part. Digital clothing defines clothes of new generation equipped computer, digital installations. Digital clothing design demands intercept of electromagnetic waves, light-weight and esthetic appearance, for it is attached high-technology equipment near body. The purpose of this study is to analyze design features of digital clothing according to ubiquitous characteristics. The methods of this study are documentary research of previous study and case study. In the theoretical study, ubiquitous characteristics are function-intensive by convergence, interactivity, embedded mobility and human & emotion-oriented attributes. Based on ubiquitous characteristics, digital clothing design classified function-intensive design by convergence, design for Interactivity and multi-sensible & emotion-oriented design, because embedded mobility is a basic element of ubiquitous environment. The early days digital clothing design is function-intensive design, and have esthetic appearances and design for interactivity increasingly. Recently digital clothing design is expressed multi-sensible and emotion-oriented design.

Purpose: As the energy consumed by buildings increases, there is a growing need for studies and technology development to address this issue. One of the solutions to excessive energy use by buildings is the light-shelf, which is a natural lighting system enabling efficient reduction in light energy, and research in this area has been intensive. However, most of the studies about the light-shelf are limited to the light environment, and thus the application of their findings to an actual environment in the form of a design may be problematic. Therefore, the purpose of the present study is to provide fundamental data for light-shelf design by carrying out a light-shelf performance evaluation on the basis of the light environment and the heating and cooling environment. Method: In the present study, a testbed was established to conduct a light-shelf performance evaluation by measuring the electric power consumption of lighting and heating and cooling devices depending on the existence of a light-shelf and its angle. Result: The findings of the present study are as follows: 1) With respect to the uniformity of the indoor light environment amenity, the optimum angle of a light-shelf was found to be $30^{\circ}$ for the summer solstice and the winter solstice. 2) With respect to the reduction of electric power consumption by indoor lighting devices, the optimum light-shelf angle at the summer solstice is $30^{\circ}$, at which time electric power consumption may be reduced by 10.2% in comparison with when no light-shelf is applied. However, at the winter solstice, a light-shelf may increase the energy consumption for lighting in comparison with when no light-shelf is applied, and this should be taken into account in the design of a light-shelf. 3) In terms of reducing the electric power consumption of heating and cooling devices, the optimum angle of a light-shelf was found to be $30^{\circ}$ for the summer solstice, while a light-shelf is inappropriate for the winter solstice since a light-shelf creates shade and thus increases the heating energy consumption. 4) To summarize the findings above, the optimum angle of a light-shelf is $30^{\circ}$ for the summer solstice, but the installation of a light-shelf may in some circumstances increase the energy consumed by lighting devices as well as by heating and cooling devices. Therefore, more studies and technology development may need to be performed to solve the problem of increased energy consumption at the winter solstice.

디지털 환경의 전자 상거래는 종래의 물리적 환경(현실환경)에서의 상거래와는 마케팅, 유통구조 둥 여러 측면에서 차이를 나타내고 있으나 특히 소비자의 상품 구매형태에 큰 차이가 있다. 기존의 구매패턴은 제품을 보고 만지고 시험하면서 체험적으로 느껴, 제품의 가치를 판단하여 구매하였는데 이에 반해 디지털 환경하의 전자상거래는 컴퓨터 모니터화면에서 얻은 정보에 의해 제품의 가치를 판단하게 되어 구매 판단의사를 결정하게 된다. 현재 출시되고 있는 제품의 대다수는 상거래 공간이 디지털 환경이 아닌 현실환경으로 설정하여 일련의 디자인 프로세스에 따라 소비자에게 어필할 수 있게끔 디자인하였다. 그러나 하루가 다르게 디지털 환경인 사이버공간에서 전자 상거래가 이루어지는 이 현실을 감안하여 본다면 디지털 환경에 적극적으로 어필할 수 있는 디자인물을 내놓아야 할 것이다. 서로 다른 두 환경에서 또 같은 제품디자인의 이미지를 피험자들은 어떻게 인식하고 있는지를 파악하기 위하여 요인분석을 실시하였다. 그 결과 제1요인에서 서로 상이한 이미지를 가지고 있음을 알 수 있었다. 상이한 이미지를 가지고 있는 배경에는 각각의 환경에 따를 이미지에 영향을 미치는 조형적 요소의 전달이 상이하기 때문인 것을 알았다.

Nowadays major shipbuilding companies are trying to expand their business not only to shipbuilding but to offshore projects as well. DSME is one of them. DSME is trying to set up a flexible design and construction environment for shipbuilding and offshore construction in a single shipyard. The shipbuilding and offshore projects, however, have their unique technology but they need to be designed and constructed in one site. To support this new requirement, DSME has developed an integrated CAD system for ship and offshore projects. In this integrated design environment, the designers can design commercial ships and offshore projects in a flexible manner. Concurrent design is very important for ship and offshore design. As compared to the complexity of the product, the design period is quite short. In effect, the design system for the ship and offshore project has to support concurrent design. One essential point of concurrent design environment is a product model based design system. DSME has developed and implemented the 3D product model concurrent design environment based on Tribon M3. Tribon is a widely used CAD system in shipbuilding area that is developed by Tribon Solutions. DSME has both customized the Tribon system and developed in-house application systems to support its own design and production procedures. All the design objects are modeled in one common database to support concurrent design and accurate production. The major in-house development focused on the modeling automation and automatic drawing generation. During the drawing generation process many of the additional production information are also extracted from the 3D product model. In addition, several applications and functionalities have been developed to apply the shipbuilding based Tribon M3 system to offshore projects. The development of shape nesting, tubular connection, isometric drawing, grating nesting systems are the typical.
