This study used a building model made up of cement, brick, and wood to measure temperature and relative humidity for 3 days in a closed environment with a diameter of 900 mm, and performed a comparative analysis of the effect of types of building materials on the indoor temperature environment and heat transfer characteristics. The water installed inside the building model represented the person in the room and was used to assess how the environment effects the person. Wooden building model showed the lowest heat loss due to the higher thermal insulation properties than cement and brick buildings. The thermal comfort of each building model was calculated using temperature and relative humidity, and the wooden building model created a more pleasant environment than the cement and brick building models.

Sound absorption coefficients of oak (Quercus mongolica) wood and oak mushroom bed log were measured by the two microphone transfer function method and anatomical features of oak mushroom bed log examined by stereo scope and SEM observations. The sound absorption coefficients of oak mushroom bed log seemed to be higher than those of normal oak wood specimen over all estimated frequency range. Especially, in the frequency range of 2 to 6 kHz, they were about 2~3 times higher than those of normal wood specimen. Due to fungi degradation, the specific gravity of oak mushroom bed log decreased about 70% than that of normal wood. For oak mushroom bed log, abundant pores occurred on the radial, tangential and cross sectional surface and it was considered that the pores behaved as a sound absorbing pore.

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.

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).

The purpose of this study was to estimate the resistance capacity of a traditional wooden house with shear walls made of wood panel. In order to achieve the purpose of the study, the load - displacement test was carried out and the resistance moment values of the shear walls were proposed. The shear walls were made by placing studs with a nominal dimension of $38mm{\times}89mm$ at intervals of 600 mm, and attaching 12 mm thick plywood with 8-d size pegs at intervals of 150 mm. The type of traditional building wall was classified and showed the moment resistance ability of each wall type. This value is expressed as a proportional value divided by the moment resisting capacity of the standard size shear walls not divided into the divided small frames. Although some frames have proportional values larger than 1.0 even though they have openings, most of them show values smaller than 1.0. Also, even without the openings, it showed a smaller value than 1, such as 0.84 and 0.67.

The purpose of this study is to identify ways of remodeling from the traditional hanok to the modern local governmental facility in 1910s. Analysing architectural drawings in the National Archives of Korea, 58 hanok remodeling cases of 52 facilities were verified like the provincial office, county office, county court from 1907 to 1910s. Using hanok as the local governmental building, exterior walls were all changed to the scaled-wooden wall like one of western-wooden building in 1910s and the western-style entrance was set. Change of the plan caused by remodeling interior walls had an intention of the centralized closed plan. Remodeled semi-outer corridor using the space of the eave became changed to the inner corridor with expansion of space. Expansion of hanok for spatial demand was in three ways. First was the expansion towards the eave space, second was direct extension from hanok, and last was the use of external corridor to the new building. Using the eave space was simple but had limitation of space, it was planed with other expansion ways. The way of direct extension was usually used than the one with the corridor, because it was more economical way.

In the 7th century, Sachunwang-sa temple had two extra building-sites behind the Main hall. These two building-sites were found to be in peculiar form different from any another existing stone bases. The stone bases of northern put of these building-sites were decorated to molding as the protruding comers of eaves, which was pierced into a circular hole, and was carved into a form of Gomeck-ii(the stone bases lot supporting the wall). The northern building of sachunwang-sa temple was found to be used as the altar following munduru(文豆婁) method, through the observations of the archives of Samkukyusa(三國遺事) and the Abhiseka stura(skt. 灌頂經). The molding as the protruding cornets of eaves of stone bases was shaped as the roof of a building and the carving of Gomeck-ii gives a proof of the existence of the wall between columns in the altar. The hole of the stone bases protected the wooden cylinder of munduru from the exterior world. The author concludes, through this research, that the altar of Schunwang-sa temple was used lot the religious service during the war for worthship and protecting from the enemies. Also he concludes that these buildings must have been in wooden pagodas constructed upon a square plan, that is with both front and side width equal, haying a quite small scaled and low floored building with its first floor closed on all sides, being different item the usual form.
