Termites are a group of social insects that are one of the primary causes of damage to wooden architectural heritage. Since termite damage impairs the authenticity and structural stability of cultural heritage, it is imperative to prevent it. This study examines the extent of termite damage to wooden architectural heritage as part of efforts to prevent termite damage to nationally designated wooden architectural heritage sites across the country. The extent of termite damage to each cultural heritage was assessed qualitatively and quantitatively and comparatively analyzed by region using the results of the "Investigation on Biological Damage to Wooden Architectural Heritages" conducted by the National Research Institute of Cultural Heritage from 2016 to 2019. It involved 362 nationally designated wooden architectural heritages(25 national treasures, 157 treasures, 180 national folklore cultural heritages) and 1,104 buildings. The results were as follows: termite detection dogs reacted at 317(87.6%) of the 362 wooden heritages, with visible termite damage observed in 185 cases(51.1%). Furthermore, termite damage was confirmed using one of two methods(detection dogs or visual inspection) in 324 cases(89.5%). Of the 1,104 buildings, termite detection dogs reacted at 668(60.5%), while 339(30.7%) showed visible termite damage. Employing one of the two methods, damage was confirmed in 702 buildings(63.6%). The country was categorized into nine regions(Seoul Metropolitan Area, Gangwon, Chungbuk, Chungnam, Jeonbuk, Jeonnam, Gyeongbuk, Gyeongnam, and Jeju) to examine the termite damage rate and the degree of damage to each cultural heritage according to location. Termite detection dogs reacted to more than 70% of the cultural heritage in all regions. Visible damage was minimal in the Seoul metropolitan area(32.1%) and Gangwon(21.4%) but severe in Chungnam(65.6%), Jeonnam(67.3%), and Gyeongnam(68.2%). By quantifying the degree of termite damage of each cultural heritage as a ratio of the absence of termite damage among the total absence, the average termite damage of the cultural heritage across the country was 9.2%. Regional variance analysis showed that the cultural heritage in Jeonbuk and Jeonnam showed a statistically significantly higher degree of termite damage than the cultural heritage in the Seoul metropolitan area, Chungbuk, and Gyeongbuk. This paper comprehensively analyzed termite damage to nationally designated wooden architectural heritage. The findings are expected to be valuable in establishing policies for the preservation and management of cultural heritage sites in the future.

The purpose of this study is to improve the repair and reinforcement of cultural construction assets made of wood and develop seismic countermeasures. The existing regulations for the earthquake proofing of cultural assets are termed 'Regulations concerning earthquake disasters affecting cultural assets' of the cultural heritage administration, which only specifies the reporting of damage to cultural assets after the occurrence of an earthquake. Since 2013, Korea has been studying the introduction of a seismic evaluation system consisting of experts by referring to the 'Guideline for the diagnosis and reinforcement of important cultural properties in Japan. The earthquake proofing of wooden cultural assets in Japan is assessed by experts using a scoring system similar to the one in Korea, but the system in Japan is managed in three steps, viz. before, during and after the occurrence of the earthquake. In order to extend the existing management system by focusing on the repair of the damage after the occurrence of an earthquake, it is necessary for Korea to cultivate experts for the regular management of cultural assets, establish seismic criteria for them, and introduce a regular management system through a civil organization related to construction. By examining the current status of wooden cultural assets, it is necessary to develop various seismic diagnosis techniques and produce guidelines for the repair and reinforcement of individual wooden cultural construction assets following their identification.

In this study, the status of damage by subterranean termites and their management according to the region and type of domestic wooden cultural properties were identified. This was based on the survey reports of agencies conducting regular nationwide and regional monitoring of subterranean termites. In addition, using geographical information system (GIS) based on the survey contents, a map was constructed of termite infestation and its progress on 2,805 wooden cultural properties that were surveyed nationwide. Based on the map produced, a total of 486 cases of termite infestation were confirmed in wooden cultural properties during 2018-2019, of which 143 cases (approximately 29.4%) were confirmed to be owing to the invasion of termites in the ground and infestation of wood materials. A web platform and an application using a mapping application program interface were created to increase accessibility to the investigated damage status data. The methods employed by each institution for investigating and monitoring the invasion of termites in the ground included the use of detection dogs, visual observation, installation of wood specimens made of pine, and microwave equipment. However, it was confirmed that monitoring and survey methods were not applied to determine the territorial range of the subterranean termite colonies. Accordingly, the use of dyeing and mark-release-recapture methods were deemed necessary to understand the current status, such as calculating the scope of the target wooden cultural property, when monitoring subterranean termite colonies.

새로운 목재사용 전통목조건축 재현 연구-우리나라에서 건축 부자재로 사용되는 목재는 거의 수입에 의존하고 있으며 시멘트 등을 재료로 한 건축이 늘면서 전통적인 우리의 건축양식이 사라져 버렸다. 이런 상황에서 서울대 임산공학과 이전제교수(47세)는 우리의 전통목조건축을 새로운 목질재료를 사용하여 재현할 수 있는 연구를 하고 있다. 서울대 미식축구부 지도교수 겸 감독을 맡고 있는 이교수의 학문세계를 조명해본다,

최근 친환경 자재를 사용한 건축물이 증가하면서 전통 가옥 뿐만 아니라 다양한 형태의 목조 건축물들이 많이 지어지고 있다. 목재는 건축자재로서 우수한 장점이 많은 반면 화재에 취약한 치명적인 단점을 갖고 있다. 본 연구는 목재건축물의 화재특성을 분석하기 위하여 목재건축물의 화재해석 모델링을 구성하고 수치해석하였으며, 화재시 화염전파의 패턴을 분석하였다. 발화는 내부발화와 외부 화염전이로 구분하였으며 내부발화는 다시 건물 중앙 발화와 벽면발화로 구분하여 수치해석을 수행하였다.
