Hanok is a cultural heritage containing our ancestor's life style intact and breathing alive with us until now. As Hanok has been concerned as a echo-friendly architecture, a new methodology for efficient construction without damaging the traditional construction process comes into request. The goal of this research is development of a architectural design tool based on the BIM(Building Information Modeling) for satisfying these demands. It will be usable to support whole process of the traditional building from digital design to production and construction. Firstly, we take a consideration of the traditional architecture reflecting the spirit of the age and suggest efficient design method for architectural components. Each components is pre-fabricated as a template representing similar components. All pre-fabricated components are designed by object-oriented concepts so, many variations for a component can be derived from the pre-fabricated component. Our method is helpful for reducing design errors because that it considers combining rule between connecting components in the template design. Moreover it is plugged in the commercial architectural CAD, so it can supports digital design not only traditional architecture but also fusion style mixed with modern architecture.

The number of architects who adopt BIM(Building Information Modeling) as the design method are gradually increasing because of its productivity and efficiency. Climate Change and Global Warming lead to legislation of new energy regulations and strengthen existing ones. The current architectural design methods (2D CAD) take a lot of time and effort to verify energy codes and are hard to adjust according to the design changes. The purpose of this study is to show the effectiveness of the BIM in building envelop energy modeling of the housing project. In the process of design method change, We could contribute to increasing productivity and efficiency in building energy verification through BIM because the updated value could be calculated simultaneously without information omission or recalculation process. The procedure for the study is as follows. Using BIM of the Goldin at Essex Crosing Housing Project by Revit 2011 as a case model, this study analyze the criteria for energy plan to conform to the energy code in NYC. The result value from the setting of the Revit model is compared with the reference value required by the NYC Energy Code. Finally, the data from BIM are entered into COMckeck, the energy verification program provided by U.S. Department of Energy, to check whether the building envelope energy performance conforms to NYC Energy Code.

Recently, the interests in the 3D image, generated from the range data and CAD, have exceedingly increased, accordingly a various 3D image database is being constructed. The efficient and fast scheme to access the desired image data is the important issue in the application area of the Internet and digital library. However, it is difficult to manage the 3D image database because of its huge size. Therefore, a proper descriptor is necessary to manage the data efficiently, including the content-based search. In this paper, the proposed shape descriptor is based on the voxelization of the 3D image. The medial axis transform, stemming from the mathematical morphology, is performed on the voxelized 3D image and the graph, which is composed of node and edge, is generated from skeletons. The generated graph is adequate to the novel shape descriptor due to no loss of geometric information and the similarity of the insight of the human. Therefore the proposed shape descriptor would be useful for the recognition of 3D object, compression, and content-based search.

In spite of intense advances in the economy and technological progress which include massive and high-rise developments, landscape resources have either been destroyed or left to deteriorate. In recent years, efforts towards landscape management have emerged in the form of legislation and policies. However, relevant computer tools have unfortunately been insufficient in the field of landscape management. In addition, although there has been much research conducted for urban landscape management, pertinent information has not been recorded or managed efficiently. Therefore, this study developed a Landscape Information System for the purpose of managing urban landscape infOlmation and analyzing visual impacts in relation to urban development projects. Main functions of the Landscape Information System consist of the following: inputting and managing the attribute data as well as graphic data, querying attributes of urban landscape, and analyzing landscape impacts of developments. A case study was conducted for downtown Seoul. Using the system, a series of visual impact analyses were implemented at major viewpoints in the area. The results have shown that valuable landscape resources could be damaged by proposed development projects. Thus, the Landscape Information System developed in this study can be used as a major tool to manage urban landscape information efficiently and as the basis for decision-making regarding landscape simulation and visual impact analysis.

As the shipbuilding and offshore plant industries grow larger and more complex, their maintenance and inspection systems become more important. Recently, maintenance and inspection systems based on augmented reality have been attracting much attention for improving worker's understanding of work and efficiency, but it is often difficult to work with because accurate matching between the augmented model and reality information is not. To solve this problem, marker based AR technology is used to attach a specific image to the model. However, the markers get damaged due to the characteristic of the shipbuilding and offshore plant industry, and the camera needs to be able to detect the entire marker clearly, and thus requires sufficient space to exist between the operator. In order to overcome the limitations of the existing AR system, in this study, a markerless AR was adopted to accurately recognize the actual model of the pipe system that occupies the most processes in the shipbuilding and offshore plant industries. The matching methodology. Through this system, it is expected that the twist phenomenon of the augmented model according to the attitude of the real worker and the limited environment can be improved.

The purpose of this study is to analyze the symbolism of traditional Korean patterns which reflect an emotional cultural background of Korean people, to apply modernized and developed patterns to Textile Design for fashion cultural products, and to explore productive direction of developing designs of fashion cultural products. The process of developing Textile Design of fashion cultural products which applied symbolism of traditional Korean patterns was conducted as follows. Firstly, based on '05 S/S-'07 S/S fashion trends, a design concept wat decided(man-urban ethnic style, woman-romantic ethnic style). Secondly, motive was abstracted from selected traditional patterns to develop into modem patterns. Thirdly, items were selected according to symbolic meaning of traditional Korean patterns. Man's items included shirts, necktie, and handkerchief which were highly preferred by Korean and foreign visitors. Finally, developed textile designs were diagrammed by item using textile CAD and an illustrator 10 and presented as images. The following results were obtained. First, textile designs for fashion cultural products, in which apply traditional patterns may reflect the understanding of traditional aesthetic beauty and philosophical approach by applying symbolic significance inherent in patterns as well as the aesthetics of the patterns. Second, traditional patterns have been recognized as old fashioned to consumers because they have been often used for traditional handicrafts or folk products. If their unique shapes are changed or simplified, emphasizing images, and trend styles and colors are used, they will be recreated as a modem design. Third, textile designs using traditional patterns may provide various images and visual effects according to techniques and production methods. Then, the method will be applied to many items. Finally, since traditional patterns in fashion cultural products can be used as our unique design elements, they can be utilized as the source of design inspiration for the development of value-added products.
