The purpose of this study was to search the architectural forms including the residence plan and wooden structure and the measuring unit in building sites named Bang in Gyeong_Ju, the capiatal of Silla dynasty. It includes the following three historic sites: JaMaeJung-ji, the east district of HwangLyong-sa (S1E1) and InWang-dong historic site. Especially, the data from excavating and studying the east district of HwangLyong-sa were very precious and meaningful. The results were as follows: 1) There are individual characteristics at the sites of JaMaeJung-ji, the east district of HwangLyong-sa and InWang-dong. 2) It is assumed that the builldings of the east district of HwangLyong-sa had most various types of plan and various types of wooden structures. 3) There were various types of wooden structures like as symmetrical or asymmetrical style, regular columnar or irregular columnar style and a third purlin location or a forth purlin location. 4) This study also showed there's a high probability that buildings at Bang sites had been built by the Tang dynaty scale. In Silla dynasty, there was similar tendency to BackJe Dynasty in the way that measuring unit changed according to the times.

The Yoon Jeung residence is a well-known and prototypical aristocratic house example showing typical and interesting characteristics of the traditional houses in the middle region of Korea. When it comes to understanding the architectonic characteristics of a Korean traditional house, it was not easy to actually capture the compositional and/or constructional knowledge of the building even though it is a wooden building with many wooden members showing their compositional relations. Now with the help of the BIM tool, the Building Information Modeling tool, we could actually be able to compare and analyze each member and their compositional relations. In this paper we examine the unique traditional composition method used in extending the building's structural sections utilizing the bended-joint characteristics of traditional buildings with exemplar case of the Yoon Jeung residence. Thereby we examine those relationships among three major compositional parts namely the plan based spatial compositions, the upper wooden compositions and the roof forms so as to specify the building's typical characteristics with reasonably acceptable causes. The inner and outer block of the residence are handled with their bended-joints with more detailed knowledge of categorization by way of joint relationships among members.

Airtightness of buildings is one of critical aspects of its energy performance. To build up references of airtightness of wooden houses built in Korea, blower door tests have been carried out in 42 houses since 2006. Causes of air leakage were investigated recently. The average value of air change rate was $3.7h^{-1}$ for light frame house and $5.5h^{-1}$ for post-beam construction at ACH50 (air change per hour at 50 Pa air pressure difference). Foam type insulation was more advantageous in ensuring building airtightness than glass fiber batt. Airtightness of wooden houses which were constructed after 2010 was improved to have less than $1.5h^{-1}$ of ACH50, threshold for application of artificial air change. The average air change rate of CLT (cross laminated timber) houses showed the lowest value, $1.1h^{-1}$, among the tested structures.

There are several methods of pest control for the prevention of wooden cultural properties from damages caused by insects, especially termites. Those are as follows; physical control, chemical control, biological control, and integrated pest management. In Korea, we primarily use mvestigation of monitoring, fumigation, treatment of insecticidal and antiseptic chemicals, soil termiticide treatment, and termite colony elimination system. As damages by termites were detected at Eunghyanggak and Saundang of Haeinsa temple in June, 1998, we carried out monitoring with wooden device, in order to investigate damages of wooden building by termite and paths of termite invasion. According to the result of investigation of monitoring from1999 to 2002, we found that termites were inhabiting continually at forests around Haeinsa and that wooden buildings such as Saundang, Cheonghwadang were damaged by termites. So we thought that control methods such as soil termiticide treatment and termite colony elimination system would be effective. Especially, to investigate efficacy of termite colony elimination system, we carried out efficacy test of termite colony elimination system in Jongmyo during 17 months(2000.7.~2001.11.). The result of efficacy test showed that termite colony elimination system eliminated termite colonies gradually(over 12 months from installation of colony elimination system to elimination of termite colony).

San-ja is one of the main members consisting of the roof of traditional wooden buildings in Korea. In this study, the regional characteristics of the materials used in San-ja and changes of the materials over time were examined. To this end, 123 documents on the repair of wooden architectural heritage recorded since the 1950s were reviewed. It was found that there was a difference in the San-ja material by region because of the diversity in the conditions of material supply. For instance, bamboo was the most frequently used material in Jeollanam-do province because it was readily available. However, with the development of transportation and vehicle, the regional characteristics have disappeared. As a result, the material has been unified with bamboo now. This is because bamboo is specified as a representative material in the specification or the convenience of construction is prioritized. In addition, the social and economic conditions at the time of repair had an influence on the selection of the San-ja materials.

It was believed that Jeongnimsa temple was built after the capital was moved from Gongju to Buyeo. It was confirmed that it was built A.D. $625{\pm}20$ by conducting a paleomagnetic analysis on the fireplace, which was recently found at the bottom of Jungmunji(middle gate). Consequently, it is assumed that the temple was built in the early 7th century unlike the previous point of view. Therefore, this study evaluated if the fireplace at the bottom of Jungmunji was found at the geological stratum representing the Jeongnimsa temple. Moreover, the study examined when the fireplace at the bottom of Jungmunji was constructed on the soil stratum. It is possible that the fireplace was built in the early 7th century as shown in the paleomagnetic analysis. However, when we compared the soil strata of the Jungmunji and the existing five-story stone pagoda, it showed that the ground was prepared differently and they were built over a fairly long period of time. Furthermore, I discovered that there was a wooden pagoda under the five-story stone pagoda by examining the soil strata map. Therefore, previous studies evaluated the arrangement of auxiliary buildings of Jeongnimsa temple and concluded that it was built in the early 7th century. It is hard to determine when the temple was built based on the arrangement of auxiliary buildings, because it takes a long time to build a temple and auxiliary buildings can be relocated during this long construction period. Rather, we have to admit that there are various arrangement patterns through minor changes in buildings from the one pagoda and one main building(Geumdang) arrangement.

Title of management of cultural asset architectures made of wood managed by nation or local government is separated and there is a high concern about the disappearance of many national cultural asset architectures by fire. This study investigated the effectiveness of major installed appliances in terms of disaster prevention, and problems by early suppression in the event of fire and by mobilization of fire engines in depth. Also, this study derived problems by conducting an in-depth individual interview on interested parties for installation of fire extinguishing system by related law and to improve system to make realistic maintenance. As a result, it was identified that they have reached the positive aspects of protecting cultural asset architectures from disaster as fire by maintaining and managing facilities by establishing proper disaster prevention measures because they are surrounded by mountain or buildings are contiguous. Wooden cultural asset architectures are often excluded from regulation for installation of fire-fighting facilities under the Fire Services Act because most of wooden cultural assets are detached buildings, occupy small area, and are one-storied architecture. The best method is having extinguishing ability themselves according to the manual by making fire manual as management policy before the outbreak of fire. This study intends to suggest a follow-up study for practical considerations to establish or designate a professional management agency for them to protect important national cultural heritage buildings at the state level before they are destroyed by fire.

This research was performed to supplement the previous research about the driving rain index (DRI) for Korea determined by using daily weather data for 30 years. The average annual driving rain index (AADRI) was calculated from the hourly weather data, and the magnitude of DRI was investigated according to wind directions. The hourly climate data were obtained from the Korea Meteorological Administration (KMA) for the period 2009 to 2017. Of 82 locations investigated, seven were classified into regions where the level of exposure of walls to rain was high. The result showed quite a difference from the previous results, in which no high exposure regions were observed. Since the hourly-based and the daily-based annual driving rain index (ADRI) values showed only a slight difference, the result may be explained by the length of the periods used in both studies. The change of DRI according to wind directions showed that there was a certain range of wind directions in which driving rain easily approached building walls. It suggests that the consideration of wind directions with high DRI would be useful to develop a good design of wooden buildings from the point of wood preservation and maintenance.

This study examines on the structural Methods between purlin and beam at Wooden Architecture in Joseon Dynasty($1372{\sim}1910$). Through the investigation, it is verified that the structural methods between purlin and beam is the technique utilizing tenon joint(통장부맞춤), Sungeoteok joint(숭어턱맞춤), dovetailed tenon joint(주먹장맞춤). And the methods of tenon joint is followed by the Sungeoteok joint, which is used in the buildings after middle Joseon dynasty. The method of tenon joint(통장부맞춤) is to connect the beam with the purlin by carving out the head of the beam as '一' shape. And the structural methods between Janghyeo(장혀, timber under purlin) and beam is halved joint(반턱맞춤) and tenon joint (통장부맞춤). The buildings in late Goryeo Dynasty and Joseon Dynasty adopted the method of tenon joint between purlin and beam. The method of Sungeoteok joint is to connect the beam with the purlins by carving out the head of the beams '凸' shape. And the structural methods between Janghyeo and beams is halved joint(반턱맞춤) and tenon joint(통장부맞춤), the method of tenon and step joint(통장부턱맞춤), dovetailed joint between beam and Janghyeo to increase the security of shear force.

Gachiljang(假漆匠), along with Jinchiljang(眞漆匠), is an important craftsman who cannot be left out during the finishing process of wooden furniture and wooden buildings during the Joseon Dynasty. The current definition of Gachiljang does not properly explain the nature and role of Gachiljang. In many related terminology dictionaries, Gachiljang is defined as "artisan who dose the base paintwork of Dancheong." But an analysis of the Joseon Dynasty's Uigwe(儀軌) shows that Gachiljang appears frequently in works that are not related to Dancheong at all. Therefore the current definition seems to be inaccurate and need to be revised. Gachiljang is a name that contrasts with Jinchiljang, and he makes and paints Myongyu(明油). Just as Jinchiljang uses not only lacquer but also various pigments to paint colorful lacquer, Gachiljang also uses various pigments to decorate buildings or furniture in a fancy way and then finishs with a transparent paint. Even in the Dancheong(丹靑) work of the building, all the base painting and finish coating work will be in charge of Gachiljang, except for the paintings performed by the Whawon(畫員) or the Whasa(畫師).
