This study serves as basic research for the development of a new wood-based building finishing material that improved the weakness of inorganic materials such as gypsum board and magnesium board widely used as interior finishing materials and brought out the strength of the wood. The results of evaluating the physical and mechanical properties and the environmental effect related to hazardous substance discharge having manufactured a wood-magnesium laminated composite are as follows. The thermal conductivity and thermal resistance of WML board was improved by about 28~109 percent over magnesium board due to the low thermal conductivity of wood. The adhesive strength of WML board showed a similar result to that of plywood as it exceeds 0.7N/㎟, the adhesive standard of wood veneer which is presented by KS F 3101. Bending strength and screw holding strength were more improved by manufacturing WML board than magnesium board. The WML board manufactured in this study satisfied the criteria for emissions of hazardous substances prescribed in the Indoor Air Quality Control Act, and confirmed the possibility of development as a new wood-based composite material that can replace existing inorganic materials.

The modern unique woodworking furniture has been made in earnest from 50 years ago. Some oil from nut such as soybean, walnut and perilla, which is usually used in our common life, has been used as finishing material for the unique woodworking furniture. Recently, woodworking studio business among the whole furniture industry has grown gradually and many woodworkers uses various kinds of imported wood finishing oil. Many woodworkers use the imported finishing oil in the old ways instead of understanding the characters of the various kind of oil and It causes some serious problems in furniture finishing process. Therefore, this study aims at taking theoretical approach in wood finishing oil and presenting correct usage in understanding the types and characters of oil. Resultingly the new method of oil finishing for wood is suggested and this suggestion is to guide woodworkers into the right usage of wood finishing oil.

The use of environmentally friendly finishing materials allows us to create a space where we can feel nature and to have stability and peace in the city center. In this paper, we examined the sensitivity of people to the three café spaces where wooden finishing materials are used in the space elements that change according to people's demands for environmentally friendly space due to pollution of living environment. First, we examined the wood and finishing materials and emotional vocabulary through literature review and previous research. Second, the values of L ^*, a ^*, b^* and sR, sG and sB values were extracted by using a line spectrophotometer (Ci6X). Third, we conducted a 7 - point scale questionnaire based on the extracted 13 pairs of emotional vocabulary. Using SPSS 21, frequency analysis by descriptive statistics, crossover analysis by visiting purpose and intention, and emotional lexical factor analysis were performed. Through the study, the following points were found. First, CB (The Coffee Bean), SB (Starbucks) and HS (Hollys Coffee) showed differences in CB (65%), SB (40%) and HS (37%) in the spatial analysis. Second, CB gave color similar to the color of wall and furniture wood, but HS changed the color or brightness of wood finishing color of furniture. HS or SB showed favorable use of wood color scheme. Third, SB (26.3%) and HS (19.7%) were selected by taste. Fourth, there were differences in the items of CB, 'local-exotic' and SB 'dark-bright' in the factor value. The use of wood finishing materials differed in the atmosphere evaluation depending on the spatial factors and the color of the furniture. However, in this study, there are many factors that are insufficient in the accuracy of the ratio of the applied wood finishing material to the space element and the amount of the survey. If we further study the evaluation of emotional image according to the ratio of wood finishing materials, we think that it is necessary to study now that interest in environmentally friendly is increasing.

In order to prevent decay, distortion, bending, twist on wood products such as wooden furnitures, variety of coating materials were developed and used so far. The coating materials for wood finishing can be synthesized by natural resource or petroleum. However, these coating materials can cause contamination of indoor air quality due to emission of volatile organic compounds (VOCs). In this study, commercialized coating materials for wood finishing such as varnish, coat, and stain were evaluated on emission characteristics of VOCs. Among the varnish, eco-friendly products had about 15~46% lower TVOC emission ($1,042{\mu}g/m^2h{\sim}3,257{\mu}g/m^2h$, respectively, than typical product ($7,100{\mu}g/m^2h$). Natural resource based coating material showed lowest TVOC emission level. However, one of natural resource based waterborne stain showed higher TVOC emission level because waterborne stain already contained higher amount of natural VOC. Oil-based stain might not be suitable for indoor use on interior wall and furniture due to exceed amount of TVOC. Based on results, natural resource based coat or waterborne stain are recommenced to use on wood products.

As Korea has undergone rapid modernization, urbanization and industrialization, women's social participation has increased. Accordingly, child care facilities have shown continuous growth in numbers. However, according to research, child care facilities in Korea lag behind those in other nations in terms of quality. Given that, it seem urgent to enhance the quality of child care facilities and improve their indoor environment. Above all, overall atmosphere, colors and finishing materials are connected directly with educational effects as well as feelings and health of facility users. This study assesses the current state of child care facilities and preferences by focusing primarily on interior atmosphere, materials and colors. For This Study, 7 facilities were surveyed, and 46 subjects were participated for this study. The findings suggest that "pretty" style is preferred to "natural" style. As regards flooring material, wood floor is preferred. It is recommended to lay pastel colored carpet or PVC flooring material to the wood floor. As for wall, it is desirable to divide the wall spaces by adding wood and painting to simple wallpapers. In case of the ceiling noise absorptive material is recommended to use instead of wallpapers. For the doors, it is desirable to use contrasting materials and colors given accessibility for children. In the meantime, rather than strong primary colors, soft color or pastel colors are desirable for furniture. This study has limitations because of insufficiency of case study samples. However, it is significant in that the study results may be used as primary source of information to improve the environment of child care facilities.
