This paper suggests a comprehensive method to describe architectural components for supporting Korean Traditional Building design with only small components set in CAD system. Korean traditional buildings can be classified variously based on the their size, usage and structure type(whether ornament part, namely Gongpo, is in there or not). Moreover components can be varied according to the combining rule between them. If all of these components are presented, these tremendous components rather prevent the efficient design of traditional buildings. In order to solve this problem we present object-oriented approach to describe versatile components as one template if they are same in functional aspects. From the template, many similar instances can be derived according to the attribute value. The templates are designed in order to reflect the coupling scheme between components in the relative parameters of the templates. It leads effects of minimizing error which can be occurred frequently in the process of traditional building design.

본 논문은 한옥에 대해 건축정보모델링 기반의 설계를 지원하기 위한 부재 생성방식을 제안한다. 한옥 건축 산업화를 위한 노력은 관련 법령 개정에서부터 시공에 이루기까지 전반적으로 확대되어 시행되고 있다. 이에 따라 디지털 설계방식에서도 근본적인 한옥건축 목구조 방식에 적합한 설계방식이 지원될 필요성이 있다. 이러한 시장의 변화와 요구분석을 기반으로 건축정보모델링에 적합한 한옥부재를 개발한다. 이를 위해 한옥건축물의 구성요소를 체계적으로 파악하고 건축정보모델링 기반 설계방식을 고려한 한옥 부재의 새로운 설계 방식을 제안한다. 최종적으로 구현한 부재를 활용하여 한옥을 설계함으로써 활용도와 실효성을 검증한다.

Nowadays the widely used media in architecture include visualizations, animations and three-dimensional models. 3D digital methods using active CAM(Computer Aided Manufacturing) and CNC(Computerized Numerical Control) imaging have been developed for accurate shape and 3D measurements in freeform buildings. In contrast to a conventional building using auto CAD system and others, the proposed digital optimization method is based on a combination of 3D numerical data and parametric 3D model for design and construction. The objective of this paper is therefore to present digital optimization process for constructability of freeform building. The method can be useful in the effective implementation of an error-proofing process of freeform building during design and construction phase. 3D digital coordinate data can be used effectively to identify correct size of structural and finish members and installation location of each members in construction field. In addition, architects, engineers and contractors can evaluate design, materials, constructability and identify error-proofing opportunities. Other project participants can also include representatives from all levels of management, departments as well as workers and key subcontractors' personnel, if necessary. The 3D digital optimization process is therefore appropriate to serious variations in freeform shape. For future study, the developed digital optimization method is necessary to be carried out to verify the robustness and accuracy for constructability in construction field.

As increasing interests for cultural content, 3D restoration about the valuable traditional architectures is in progress, nowadays. Digital restoration is generally performed with using new IT technology and equipments such as 3D scanner. From the view points of making better use of the 3D data, the methodology for 3D restoration leaves much room for improvement. When using 3D scanner, it is possible to get precise 3D data for exterior of the building but huge data size and insufficient information for the wooden intra structure might be obstacles for using them as a source of various digital contents. In traditional wooden structure, the binding rules for corresponding architectural components are important factor for realizing the architectural culture at that times. In this paper, we develop a design tool and architectural components reflecting the wooden intra structure. Moreover, we propose a new 3D restoration method from the design tool, which is good for making contents offering useful information for processes of construction and binding rule in a real time just at a glance.

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.

최근에 전통건축에 대한 우리의 관심이 높아지면서 한옥마을 조성 등으로 인한 관련 산업의 수요가 활성화 되고 있으며 이에 따라 전문가 육성에 대한 요구가 증가하고 있는 추세이다. 그러나 설계전문가라 하더라도 전통건축을 처음 접하는 경우에는 부재간의 연결 관계를 명확하게 인지하는데 많은 어려움을 겪게 된다. 본 연구는 이러한 어려움을 해소하기 위한 방안으로 현재의 발달된 인터넷 환경과 급속히 확산되고 있는 모바일 단말기의 장점을 충분히 활용할 수 있는 교육용 콘텐츠 개발에 관한 것이다. 부재의 결합규칙을 분석하고 이를 토대로 전통건축의 목구조 방식을 이해할 수 있는 교육용 콘텐츠를 개발한다. 디지털화된 전통건축 정보를 활용하여 부재간의 연결과 이음방식을 점진적으로 이해할 수 있도록 단계별 인터페이스를 제공하며 플랫폼에 자유로운 교육용 콘텐츠를 제작한다.

The most critical issue in free-form buildings is how to construct the free-formed exterior facade panels. Their geometric complexity delivers many cons and problems in fabricating and constructing their shapes. To construct a free-form building, first of all, its skin has to be chopped into small pieces, which is called panelization. After panelization, the panels go through an optimization process to construct them economically. The panel's geometries are modified or regenerated through this optimization process. In this study, the panel optimization process of free-form buildings are performed through a case study. The panel shapes of the case study are modeled with Digital Project. To test the constructability of the various panels, 8 mock-up panels are made and laser scanning technology is applied to measure the preciseness of the panels manufactured in comparison with their original design.

MPEG-4 디지털 콘텐츠는 통신, 컴퓨터, 방송, 모바일 등의 다양한 분야에서 멀티이디어 데이터를 처리하기 위한 표준으로 자리 잡고 있다. 하지만 저작권 보호 및 관리 시스템의 부재로 기업간 저작권 시스템의 문제와 관심이 대두되어 ISO/IEC의 산하기관인 MPEG에서는 MPEG-4 시스템 표준에 부합되는 IPMP(Intellectual Property Management and Protection) 시스템 인터페이스를 표준으로 제정하여 저작권을 보호하고 관리하는 공동 방법을 제공하였다. 이에 본 논문에서는 기존 MPEG-4 저작도구에 기반하여 MPEG-4 IPMP 시스템을 플러그인처럼 추가할 수 있는 확장 시스템 구현을 목적으로 두고 있다. 설계 부분은 IPMP 정보 저장부, IPMP 정보 변환부, 멀티미디어 처리부, XMT-A to MP4 컨버터, IPMP 정보 처리부로 구성하였고. 저작자가 IPMP 정보를 효율적으로 입력, 수정하고 시스템에서 처리되도록 구현하여 표준에 따라 보호 및 관리 신호를 갖는 MPEG-4 디지털 콘텐츠를 저작하였다.
