The objectives of this study is to analyze the characteristics of Chinese traditionality expression at restaurants in Beijing area. 12 restaurants were selected and visited for the investigation research. The results were as follows. First, traditional reproduction was found mainly manifested through the reproduction of traditional ornaments, in particular, the facade and interior element ornaments. Second, Traditional transformation was mainly manifested in replacement material while changing the shape slightly, or to stretch or shorten prototype shape and other negative deformation methods which did not largely out of the scope of traditional reproduction. Third, Traditional reinterpretation was expressed by abstract, symbol or metaphor on designs, usually people can not directly recognize the traditional archetype. When compare with traditional reproduction or traditional transformation, traditional reinterpretation was relatively fewer, however, in this study the traditional reinterpretation and traditional transformation have same numerical result. Reinterpretation as a positive performance method of traditional modernized, it was encouraging the phenomenon, especially in the ceiling design. Chinese traditional cloud patterns have been three-dimensional and diversification of use. And in the wall design, traditional elements have been extremely simplistic or adopted a wide variety of traditional elements, it may be preferred in diversity. In addition, furniture was tinge traditional elements in modern form, lighting was added symbolize color or picture on the traditional lighting which shape was simplified to emphasize space's traditional. But the facade, sign board, floor, and window element seems the range of variation was not wild, promote more use the positive traditional reinterpretation method.

The objectives of this study are to obtain the basic knowledge of anatomical characteristics and wood properties of thinning trees of young teak (Tectona grandis L.F.) for fulfill the timber demand in Indonesia. Nine thinning trees of 5-year-old teak clone trees were used for analyzing the cell morphology and air-dry density. Vessel diameters in pore and outer pore zones were 165 and $90{\mu}m$, respectively. Mean value of fiber diameter, cell wall thickness, and fiber length in outer pore zone were $14.6{\mu}m$, $2.07{\mu}m$, and 1.04 mm, respectively. In addition, mean value of air-dry density was $0.55g/cm^3$. The measurement and values of vessel diameter, fiber diameter, cell wall thickness, fiber length and air-dry density in the experimental had lower than those in the older teak. Therefore, it could be suggested that the wood from thinning young teaks was not appropriate as construction material, but it could be used for furniture which do not need high of strength properties. Furthermore, since the measurements values of anatomical characteristics were still increasing from pith to bark, it could be suggested that 5-year-old teak clones are still in a juvenile phase. Positively significant correlations were found between air-dry density and cell wall thickness, indicating that cell wall thickness is strongly correlated with wood density of teak.

The Annals of the Joseon Dynasty is one of the World Heritage which should be conserved well. However, some of wax treated volume of the Annals of the Joseon Dynasty have damaged seriously. Currently a variety of efforts to conserve and restore the injured volumes are continued and many studies about the aging mechanism of the wax treated volume have being progressed. The analysis of VOCs (Volatile Organic Compounds) emitted from paper cultural heritage is one of the methods to understand the degradation pathway of paper cultural heritage. The analysis of VOCs emitted from paper cultural heritage has been mainly conducted by SPME (Solid Phase Microextraction) method. SPME is potable and simple method but it is difficult to collect all VOCs emitted from a book such as the Annals of Joseon Dynasty. The dynamic chamber system has generally used to do analysis of VOCs emitted from the building materials, furniture and electric appliances. The chamber system is possible to do quantitative and qualitative analysis by a continuous $N_2$ gas flow and the proper chamber which is able to gather all VOCs emitted from the Annals of the Joseon Dynasty. In this study, the most material among detected VOCs was Naphthalene. Naphthalene has used to prevent organic cultural heritage from being damaged by various microbes for a long time. Apart from Naphthalene, main VOCs were Acetic acid, 2-Chloroethanol, 2-Bromoethanol, Furfural, 1-Methylnaphthalene, Azulene, and 2,4-Dioctylphenol. Of these VOCs, Furfural especially was known for a marker which represents a different emission rate according to the aging level.

Radon radiation exposures in home have been posed as a potential cancer hazard. This research aims to present the basic data of the indoor radon concentration level by examining the radon exhalation rates of wood species. Radon exhalation rates from five commonly used wood species in Korean wood building construction were measured with Continuous Radon Monitor (CRM), Model 1028 (Sun Nuclear Co., USA) using the Closed Chamber Method (CCM). The mass exhalation rate was observed to vary from $0.00089Bq{\cdot}kg^{-1}{\cdot}h^{-1}$ to $0.00181Bq{\cdot}kg^{-1}{\cdot}h^{-1}$, whereas the surface exhalation rate was observed to be $0.00677-0.01517Bq{\cdot}m^{-2}{\cdot}h^{-1}$. The radon exhalation rate of Quercus accutissima Carruth (white oak) which has the highest density showed the highest figure among the five wood species, on the other hand, the rest of four species showed similar results which were similar to the radon exhalation rates of wood in the U.S.A. and Canada. The average of the concentration measured by the CCM represented well up to the second half-life period (7.7 days). Because result of these small quantities seems to indicate that radon exhalation from the tested wood species has almost negligible impact, the main culprit of the high indoor radon concentration is clearly derived from the background of surrounding wood house. Therefore, as a safety precaution, infrastructures made of wood materials should be designed with the consideration of influx of radon and built accordingly. Furthermore, it is highly desirable that wood will be needed to use for furniture and interior finishing material in indoor environment.

Due to the development of technology, the modern people became to require not only more convenient life but also more comfortable and emotional environment, and individually suitable living environment is applied to residents in a residential space. Recently, while the LED lighting was variously attempted in every sector in society, it is needed to express differentiated lighting according to the resident's individual lifestyle in a residential space. In this paper, we analyze the role of LED lighting suitable for the digitalized lifestyle of the modern people through the relevant literature survey and case studies. The following results are obtained in summary of the rapidly changed recent trends of LED lighting. First, LED light replace existing light sources due to the advanced new technology in LED industry, and take the spotlight as a new lighting solution with the development of variable color LED bulb and the control technology by the wired and wireless communications. Second, LED lighting can be structurally applicable to every lighting device because of its compact and lightweight units, can produce abundant light environment by expression of variable colors and moods with the easy coloring and dimming control, can be reborn as emotional lighting design. Third, as recently practices are constantly appeared that integrate LED lights in the interior elements, such as object and furniture, and combine advanced LED lighting technology to new materials, the portion of illumination on the indoor environment is further increased after integrating the LED lighting and interior elements make boundaries of lighting and product architecture become blurred. LED lighting is confirmed that is being changed from the external functionality including material, shape, color, and etc. into the contextual emotion design including the lights expression, variable color, brightness control, making image, and etc. as the light source in current smart lighting era.

The purpose of this study was to find out the physical change of the farm house and its anbang(the main room : master bed room), to identify the behavioral changes : activity and awareness of anbang, and to clarify the relationship between the physical changes of the farm house, and the behavioral changes of housing life-style in the anbang space. Bibliographical studies, cultural approaches and field survey method with questionnaire were used to collect data from 55 residents of Anwhari and Yangkyori in Pyong Teck Koon. Tables and drawings were made to analyze the data. The major findings were 1) the heating system of the ondol anbang. The most popular type is the double heating system(new pipes added to the traditional ondol). This combination ondol system brought some conviniences to the farmers. This change in structure of the ondol were of four types : Complete change in style, enlarged-completely changed style, partially changed style, enlarged-partially changed style. 2) from 1960 through 1970 lighting of the anbang changed room oil lamp to electricity. 3) the finishing material of the anbang floor changed from traditional oil paper and straw mats to vinyl flooring. 4) Traditional furniture and small decor items are gradually disappearing and are being replaced by modern items. 5) The awareness and actual use of the ondol anbang has not much changed from the multi-functional and sacred space of daily living : which are the characteristics of Korean traditional ondol anbang. The biggest consistency in the ondol anbang is the heating system of the floor, which is the characteristic of ondol culture in Korea. This system will continue regardless of time and place in Korea.
