This study was carried out to investigate the reasonable condition for better dimensional stability in woods by polyethylene glycol(PEG) treatment. Eight species grown in Kangwon-do were used for this study. Three species of softwoods(Pinus densiflora, Pinus koraiensis, Larix kaempferi) and two species of hardwoods(Prunus sargentii, Populus tomentiglandulosa) treated with 30% aqueous solution of PEG 1000 showed good dimensional stability under the treatment for 1 day. The dimensional stability of Betula davurica, Quercus mongolica and Quercus variabilis woods increased with increasing treatment time. From the above results, it was concluded that PEG penetration and dimensional stability were affected by characteristics of wood species such as density and structure.

Laminated lumber is an engineered wood products using stress rated, seasoned and selected lumber. Each piece of lumber is graded, and then end jointed to produce the required length. This study was carried out to investigate the possibility of wooden artifacts with laminated lumber. It is expected through this research that wooden artifacts, which have originality and local character, can be developed by making design of wooden artifacts through the use of plentiful resources around the local area. A development of new design products, an improvement of distributive structure and the achievement of international competitiveness will contribute to develop the industrial artifacts art in Korea. And, it is necessary to develop a corporation system between industrial craft companies and universities.

Modern furniture is mostly made of panel products such as a glue-up panel, a particle board and a medium density fiberboard(MDF). Warping is a major defect of these panel products resulting in degrading final products. In this study the factors related to the warping of a glue-up panel and MDF were investigated by comparing the physical properties of warped specimens with those of the unwarped. The differences between the moisture contents measured on the both surfaces of specimens were found to mainly influence the warping of glue-up panel specimens whether conditioned or not. The average oven-dry density of warped glue-up panel specimens was definitely higher than that of the unwarped at l% significance level. For MDF the influencing factor on warping has not been revealed yet, however it was found that the conditioning reduced the number of warped specimens.

This study was investigated with the surface properties such as physical and accelerated tests of wood-based floorings. In physical test, hardness and abrasion resistance values of laminate floorings were higher than those of others. The center line average surface roughness($R_a$) of imported laminate flooring was highest value($1.34{\mu}m$) and that of imported solid wood flooring was lowest value($0.62{\mu}m$). In cold resistance and moist heat resistance, no defects were found on the surface of all flooring (crack, blistering, peeling, and gloss loss etc.) after testing. Wet-cold-dry cycle test showed that plywood flooring appeared some cracks. In accelerated weathering test, color difference increased with increasing Xenon arc light irradiation

The folding chairs are one of the most necessary furniture for satisfying the moderns' wants which is utilized for limited space rationally. These folding chairs are variously used in interior spaces such as offices, dining areas, and resting areas. They are very easy to move around, so that quiet useful in out door areas, too. Moreover, they play an important role in public spaces as supplementary furniture. The folding chairs have one or several axes, and they are classified according to type of axes like below. 1. Method of divide seating board into 2 and fold, 2. Method of folds seating board and lay on bottom of backboard, 3. Method of fold back board and lay on top of seating board, 4. Method of fold into contact with left and right, 5. Method of gathering legs into one and fold. The folding chairs have to be easy to operate, firm and safe, light for moving around easily, designed for able to change units whenever they have damaged. Change of residential spaces according to the trend towards the nuclear family maximized necessity of limited spaces' use. Therefore, this study provides insights for development of new methods' of folding chairs.

The studio furniture movement that expanded in the United States after the Second World War was truly American creation representing highly sophisticated individualism versus industrial anonymity. The studio furniture movement can be traced back to the 1930s in terms of its influences and emergences. Based on the ideals of Arts and Crafts movements from the earlier decades, studio furniture movement emerged in the 1950s in reaction to Bauhaus inspired industrially produced furniture. Studio furniture has represented an alternative for people who wanted individual objects in their homes rather than industrially produced products. Opposed to plastics and industrial materials, artists in studio furniture mainly focused on one natural material, emphasizing its singular beauty. There were significant roles and influences of craft education along with Scandinavian influences in terms of spreading out the movement. A historical examination of furniture from the 1930s until the 1960s illustrates how this significant movement began in the mid-century.

Compared to the fields of Interior Design and Architecture, there have been very few research studies peformed to analyze the history of furniture design in Korea. If our Country wishes to become a participant in the world of global furniture design, it will be necessary to perform more offensive research in both the design of furniture, as well as a complete documentation of our Country's history of furniture design. This study aims to detail the method of chair design by analyzing two examples of chair design. The study, once complete, will be a reference for furniture designers as a practical method, and will become basic material for ongoing studies of the Programming for chair design.

This study was carried out to develop colored-wood furniture using veneer, small-round log and fiberboard to protect forest resources through the study of minimalism. which advocates the environmental issue inherent to contemporary furniture in the postmodern era. Based on the historical and theoretical context of minimalism closely related to the environmental protection, this study suggested the technical way how to produce the environment-friendly furniture with the least use of valuable and natural log. Finally, the color-wooden furniture was developed based on the asceticism, simplification, and repetition of the minimalism in a trend of contemporary furniture design. By soaking a veneer, Psuedotsuga menziesii and small-round log, Pinus densiflora into a very-diluted organic dye, the environment-friendly and colored-wood furniture could be created in harmony with contemporary interior space, which has showed various colors such as yellow, blue, red, and green with a pastel tone. The spring wood of the colored softwood was deeply stained, while the summer wood was lightly done. By utilizing such valueless used woods which have been little in furniture production, it was possible to decrease the consumption of precious raw log such as zelkova, ebony, rose, maple, cherry, mahogany and so on. Thus, it became obvious to be able for contemporary furniture designers to produce beautiful furniture with dyed fiberboard and small-round logs pregnant with minimalism.

Environmental furniture comprises an independent design branch as distinguished from he design of street furniture. Environmental furniture helps people enjoy outdoor relaxation and cultural activities by creating convenient facilities and plays a part as the medium connecting environment and living. As a tool effecting all outdoor living conditions including home and public environment, it helps people lead a convenient and safe outdoor life. It is an important element that contributes to the image of outdoor scenery. Therefore, the design of environmental furniture should : 1)consider environment including 3R(Recycle, Reuse and Reduce) which makes harmony with nature without destroying it. 2)seek qualitative improvement by using environmental friendly materials and continuously developing new materials. 3)be assisted by the administrative support from the government to make the environmental furniture design an integral part of the city plan. The quality of a city environment will be greatly improved when people's interest in and their changed view towards environmental furniture is effected.
