The domestic wooden cultural properties applied to the sprinkler extinguishing system was confirmed extinguishing performance through fire experiments. Consists of wooden cultural properties of a fire, a flammable material is vulnerable in terms of. The scale of fire will occur to vary appearance of the initial fire in case of arson. Sprinkler nozzles of the characteristics, the discharging pressure is 1 bar and the flow rate is 80 lpm, applied in this experiment. Fire performance experiments were tested in two separated in each of the scale of the fire and cultural properties. Fire extinguishing performance test results was low in high ceilings and two or more units of the fire scale. Fire growth environment of the actual wooden cultural properties to experimental models when you consider that it is more vulnerable, sprinkler extinguishing system is required sufficient verification in order to apply fire protection of the wooden cultural properties.

Wooden houses are classified into Traditional, Modern, Platform, Timber framing types. The most popular type is Platform framing which is come from foreign culture. The foreign and Korean tree structure tend to be incompatible with Korean culture and don't fit well with modern lifestyle. In this study, it will analyze the design characteristics of the traditional and modern wooden house to solve these problems. The design characteristics will be contributed to the development of wooden architecture which is suitable for Korean architectural style and lifestyle The research consists of space analysis, plane analysis, structural system analysis, roof type analysis, and aesthetic analysis. From the analytical results the design characteristics of traditional Hanok and modern wood structure, we propose the modular elements and the inner and outer shapes of the Korean - style wooden house.

This study is based on a scientific analysis of the production method of the wooden seated Bodhisattva statue from Gwaneumsa Temple in Wando, which is currently housed at Chonnam National University Museum. The purpose was to investigate the characteristics of the statue's production through an X-ray inspection of the wooden timbers that make up its base material, a composition analysis of the surface layers, and microscopic observation. The votive prayers found together with the statue allowed the precise dating of the artifact to the sixteenth century, during the Joseon Dynasty. The X-ray transmission identified the statue as being made using the "ilmokjo"(一木造) technique, which means that the entirety of the statue excluding the right hand was produced using a single block of wood. The specimen analysis of the naturally exfoliated surface layer revealed that the current surface was coated with brass to restore the original gilt layer. These research findings added an interesting case to the existing related research and reaffirmed the academic value of this statue.

This study covers securing legal systems and institutions regarding the standards for installing fire prevention facilities to prevent fire on wooden architectural heritage. Conflicts among relevant laws were revealed and problems related to fire prevention performance, technical standards, responsibilities, etc. in the process of establishing legal fire prevention equipment and the equipment for self-extinguishing were identified through pondering over current legal systems of fire prevention facilities. To resolve the problems, at least the principle to preserve original shapes of wooden architectural heritage should be secured even though fire prevention facilities are installed and the installation process should be regulated by laws considering features of fire on wooden architectural heritage so that fire prevention performance can be guaranteed. The directions to improve installing system through legalization of design, construction, and audit review institutions and legalization of the technical standards for fire prevention facilities were suggested to guarantee performance when establishing fire prevention facilities for wooden architectural heritage.

The combustion characteristics of roof 'Jucsim' structure was analysed using real scale fire test on wooden structure heritage building. the fire test model was made to consider roof timberling internal structure for a Sunglemun. Structure of test body layed lime, soil, 'Jucsin' and ceiling board excepting roof tile to find heat propagation process by setting thermocouples. The first test to find fire growth and heat propagation process in the part of ceiling. The second test organized to find the efficiency of fire proof paint between ceiling board and inside of Jucsim structure. The third test try to get the performance level of fire proof fabric with the same manner. The result showed from the test proof the heavy smoke exposure with limited effect of fire proof paint however, reliable fire resistance effect showed in case of fire proof fabric.

This study is researched about the field trip of temples and the data for fire extinguishment manual of fire stations: it is done from June 2008 to December 2008 the 80 main temple wooden cultural properties among the 124 main wooden cultural properties appointed by the Cultural Heritage Administration. Cultural properties appointment classification, location classification, temple area, building area in a temple, building area of appointment cultural properties, a fire engine drive direction for fire suppression in a fire, distance from a fire station, and present condition of a fire administrator are researched. The cultural properties possess characteristic is in 2 cases: the whole things in a temple are appointed as cultural properties and only the wooden building is. The cultural properties are classified: the transport is possible or not. The special quality of cultural properties are classified for early correspondence and cultural properties transport in a fire and the basic data are arranged for damage limitation.

This paper proposes an efficient implementation way of traditional wooden building using Parametric modeling method which uses the relations of numerical value ratio between building materials. Building structures and order of construction for Geunjungjeon of Kyuungbok Palace is digitally implemented proving the efficiency of the suggested proposal. Although the existing digital modeling methods for traditional wooden building emphasize the exterior modeling of the building, our modeling method constructed numerous wooden materials and arranged those pieces orderly so that people can see the interior structures of the building which usually is beyond one's vision. The suggested Parametric modeling method, Multi-Object Texture Mapping, Physical Camera Restoration, and GI Renderer for implementing Geunjungjeon of Kyuungbok Palace can be practically used for digital implementation for other traditional wooden buildings.

2008년 숭례문 화재 이후 국가지정 중요목조문화재에 소화전, 방수총, 감지기, CCTV, 자동화 재탐지설비 등 수많은 방재시설이 설치되었다. 그러나 설치 및 관리에 대한 기준이 없어 안전관리에 많은 문제점이 나타나고 있다. 또한 문화재의 특수성을 고려한 별도의 법률이 아닌 소방시설설치 및 유지관리에 관한 법률에서 특정소방대상물로 분류되어 소방법의 적용을 받고 있는 현실이다. 따라서 본 연구에서는 전국에 위치한 159개 국가지정 중요목조문화재 현장조사를 통하여 방재시설 실태를 알아보고 소방시설 설치 및 관리기준 마련의 필요성을 알아보고자 한다.

본 연구는 숭례문의 진동측정을 통한 고유진동수와 감쇠, 진동모드 등의 파악을 목적으로 한다. 목조 건축물의 진동측정방법은 건축물에 손상을 주지 않으며 공학적인 데이터의 획득으로 숭례문의 시간, 환경에 따른 구조특성의 변화를 수치적으로 파악할 수 있게 해준다. 숭례문에 대하여 상시미동측정과 인력가진측정을 실시하였다. 그 결과, 숭례문의 진동특성은 장변방향으로 2.12Hz, 단변방향으로 1.56Hz로 비슷한 규모와 형식이라고 할 수 있는 흥인지문, 수원 팔달문보다 높은 고유진동수값을 얻었고 감쇠값은 장변방향으로 1.7%, 단변방향으로 1.8%의 값을 가진다. 2008년 화재로 전소된 숭례문의 진동특성이지만 앞으로 비슷한 구조 건축물에 대한 측정 데이터의 축적을 통하여 목조 건축물의 진동특성에 대한 주기식 및 성능파악에 대한 기준 및 평가자료의 근거로 쓸 수가 있다.

본 논문에서는 노후화된 목조·석조 건축물의 균열을 탐지하는 기법을 소개한다. 본 기법의 목적은 석조·목조 문화재의 시간의 흐름에 따른 관리 소홀, 균열(벌레, 날씨, 기온 등), 배부름 현상에 의한 문화재의 손상을 사전에 방지하기 위함이다. 기존에 존재하는 목조·석조 건축물의 균열, 노후, 배부름 등 다양한 결함과 변형의 탐지 방법은 접촉식 센서를 이용하여 탐지를 해왔지만, 문화재 자체의 미관을 해칠 뿐 아니라 문화재를 추가로 훼손할 가능성이 있다는 문제점이 제시되었다. 이 문제를 해결하기 위해 문화재 비 접촉형 탐지 기법을 사용한다. CCTV 및 DSLR과 같은 관측장비로 촬영한 영상정보를 기반으로 문화재의 결함과 변형을 AI 영상분석 기반 방법으로 판단하는 문제를 제안한다.
