The purpose of this study was to investigate actual condition of the modern adaptation of interior elements (wall floor ceiling door & window) in traditional house. The examined objects were 316 pictures of residential interior spaces from the 5 different monthly magazines between Jan. 1993 to Dec. 1997 The results of this study were as follows; 1. Mostly they were either parital adaptation from the original or partially transformed adaptation rather than entire adaptation of the original 2. Of the traditional interior elements adapted in residential space only specific elements were being adapted. For example. partial adaptation from the original were oiled paper flooring(Jangpan) rice papered wall (Hanji) a ceiling finish that left the rafters and beams exposed (Yondunt-chonjang) and window or door frame which is vertical lattices accented with horizontal lattices grouped into three sections(Ttisal-mun)And partially transformed adaptation were wood flooring(Chang-maru) rice apered wall(Hanji) Yondung-chonjang wind or door frame of Wan character(Wanja-mum) 3. In regard to space the mostly adapted spaces were bedrooms rather than living or dining rooms.

It is increasing the interest on the comfortable dwelling environment and the efforts to solve the problem of the floor impact noise in apartment houses have been realized, as a result numerous products have been made. The purpose of this study is to investigate the sound insulation performances according to foaming rate of floor impact noise insulators and flooring coverings in Mock-up Test Room. The test results of impact insulation performance for each floor impact noise insulators is that double structure of insulator is excel than one in low-middle frequency band and as foaming rate go up, the sound insulation performance is improved.

In order to realize high strength and light weight for various industrial facilities and structural materials, various new materials are applied to product design. Among them, CFRP has excellent specific strength and non-rigidity, and the scope of use is expanding throughout the industry, such as mobility products and building materials. GFRP is cheaper than CFRP, and has excellent specific strength and non-rigidity, and has excellent heat resistance and sound insulation, so it has been adopted as a core material for flooring and interior flooring. CFRP of twill weave structure has better resistance to deformation of fiber than plain weave structure, so the outermost layer is applied as twill weave structure in product design. After fabrication with DCB specimens, Mode I fracture toughness was evaluated according to the crack length. As the crack length increases, the energy release rate and stress intensity factor values tended to decrease overall.

This paper studied the Pingzuo(平坐) platform structure of the two story building covered with one roof during the early period of Tang dynasty, based on wall paintings, stone pagodas, brick buildings and wooden buildings might be influenced by the Tang style. Instead of Chazhuzao(叉柱造), the typical column linkage in the Song, Liao and Jin buildings, it put the boundary column just behind the wall of a bracket set. Otherwise, the column root might be seen from outside, because its bracket set was still using Touxinzao(偸心造) which did not have a lateral arm on it. And its flooring structure was also different from the Song style, it used cantilever beams instead of lateral beams supported by bracket sets.

The higher the addition rate, the less difference in kneading was found. This is because most of the cases are mixed with vinyl gloves by hand when immediately mixed in the field, so there is no problem of mixing dough according to the amount of addition. The mean increase temperature for 20 minutes was 31.6℃ for Plain, 38.1℃ for Al, 33.7℃ for Cu, and 5~7℃ for Al 20% added sample, 38.1℃ for Al 20% added sample, but 36.6℃ for Al 5% added sample. This suggests that it is possible to improve its own heat transferability by adding metal powder to epoxy adhesives.

A comparative analysis of wear resistance and shock resistance tests shows that wear resistance is up to 6 times and at least 2 times higher wear resistance than current products, even considering the limited number of turns due to too much rotation. In the case of shock resistance, there was no problem except 7.5T, but this is only a result of KS test method, so it is deemed that additional fall impact tests by various objects in daily life are needed for practical comparison.

Comparing the absorption volume of test pieces immersed over time in room temperature moisture with weight, WF absorbed about 40% more than PLAIN, and PLAIN stopped absorbing after 10 minutes, but WF continued to absorb. It is thought that the woven fabric layer of the core material continued to absorb moisture. In the heat transfer test, the test piece to which only WF was applied had a temperature difference of about 2℃ compared to PLAIN, and when the insulating liquid was sprayed, there was a difference in heat transfer properties of up to 5℃. This is judged to have low heat transfer properties of the basic woven fabric, but the heat insulating liquid also further reduces heat transfer properties.

고경도, 고광택, 고내마모성 및 고내산성 등의 물성이 요구되는 마루바닥재의 상도용 도료로는 물성이 우수하면서도 환경친화적인 자외선경화형 도료가 많이 사용되고 있다. 그 중에서도 특히 에폭시 아크릴레이트계의 올리고머는 높은 열안정성과 속경화 특성으로 인하여 목재내장재의 도료로써 많이 사용되고 있다. 본 연구에서는 아크릴레이트 관능기 수가 자외선 경화형 에폭시 아크릴레이트 도료의 열안정성 및 표면경도에 미치는 영향을 분석하고자 하였다. 조성분을 이루는 모노머, 올리고머, 광개시제 각각의 열분해 거동 및 아크릴레이트 관능기수가 달리 배합된 에폭시 아크릴레이트 도료의 열안정성을 열중량분석기(TGA)를 사용하여 평가하였으며, 열안정성과 물리적 물성과의 관계를 확인하기 위하여 진자경도계를 이용하여 표면경도를 측정하였다. 경화 전 후의 열분해 거동 및 표면경도를 비교한 결과, 자외선 경화 중에 발생하는 가교에 의해 도막의 열안정성이 부여되며, 관능기의 수가 많아짐에 따라 열안정성뿐만 아니라 표면경도도 향상됨을 확인하였다.

In this study, for using effectively domestic (temperate) small and medium diameter logs as a wooden floorboard, cross-laminated wood panels were manufactured using domestic larch and tulip woods as a base material for teak and merbau wood flooring, and static bending strength performances were measured to investigate the applicability as the base materials of wooden flooring in place of plywood. Static bending MOE was much influenced by the strength performances of the top layer lamina than that of the laminae for base materials. Bending MOR showed the higher values in tulip wood that was hardwoods than in larch wood that was softwoods regardless of the strength performances of the top layer laminae, and it was found that the values were much influenced by the strength performances of the base materials used in the core and bottom layers. However these values were 1.4-2.5 times higher values than the bending strength of the wooden floorboards specified in KS, it was found that it can be sufficiently applied to the base materials of wooden floorboards in place of plywood.
