The purpose of this study was to evaluate the relationships between the mixing ratio and water vapor sorption property of charcoal-based loess composites for furniture & building materials with environmental friendly. Charcoal-based loess composite can be easily made by blending method with water. But the composites had much brittle fracture pattern with the increase of charcoal content. That is due to the lack of loess that takes linkage role of composites. In water vapor sorption properties, adsorption ability of charcoal was about six times higher than that of loess. Therefore, vapor sorption ability was maximum at the mixture ratio of charcoal 80% and loess 20%. It is considered that wood charcoal based inorganic composite materials can be used for various purposes as a building interior & exterior and furniture members.

A model to classify domestic hardwood species for furniture applications was developed by using discriminant analysis. The results indicated that among those 36 domestic hardwoods, which have the desired properties for use in furniture parts, 15 species would possibly substitute for temperate hardwoods imported from North America and 21 species for tropical hardwoods imported from southeast Asia and western Africa.

Handling the manufacured goods is the most cost-consuming task in material handling system in wooden furniture industries. Fully automated warehouse for cartoned goods of a furniture manufacturing company was analized to provide plant engineers and managers with some important informations on the utility and profitability of the automated storage and retrieval system(AS/RS). Process-oriented simulation modeling tech-niques were used to describe the system and to propose some alternatives to promote the efficiency of AS/RS. Simulation report could be inter-preted as follows: 1. Warehouse for the furniture goods must be designed in accordance with reliable material handling program and constructed with suitable equipments depending on the specification of packed products. 2. An excess of palletized products induced the indigestion and the inefficiency of AS/RS of the furniture industry and put this high-costly system into the shade. 3. Overcrowded AS/RS of the furniture factories could regain its material handling function by cutting down the deposit of products into the automated warehouse. For this purpose, reducing the regular output and direct delivering the outside products to the destination should be considered as the definite counterplan. And additional operation of conventional handy warehouse was also expected to improve the efficiency of main AS/RS.

Most of all furniture had been produced from wood, because it is easy to obtain from our surroundings. As time goes by people want to decorate their house with new material furniture. Because it is outcome from development of material technology & industrialization. Furniture design trends of twenty century are not only the fruits of great talented furniture artists but also high-tech material engineers. In this study, I deal with a tubular steel, as an one of the most important material of furniture, and also tubular steel furniture manufactured by a cantilever method. This study researches what are special features of it, how can designers utilize it to furniture and how do they conquest defects of the material such as a sensation of coldness, hardness and so on. In this context, It is possible that create not only new shape of furniture but also new style of space through new technology innovation.

Bauhaus, founded in Weimar, Germany in 1919, represented Modernism which is proven in the field of art as well as architecture. Furthermore, in design field, Bauhaus is the essential historical event whose influence continues in contemporary design. Bauhaus furniture is simple and austere and has linear shapes which are suitable for mass production. Bauhaus developed functional furniture design such as knock-down and pre-fabricated furniture. In terms of finishes, Bauhaus furniture epitomizes the influence of De Stijl which used either achromatic colors and three primary colors or natural finishes of wood. Bauhaus contributed to furniture design field as below. 1. Success in mass-produced furniture through standardization and pre-fabrication 2. Pioneered on industrialization through collaboration between academia and industry 3. played essential role developing modem furniture by using not only metal but also such diverse materials as plywood, glass, and leather

Since Cubists represented a way of expressing image moving away from traditional illusion effect, new realities represented by collage and assemblage. Furthermore, Marcel Duchamp, a French Dadaist, suggested the concept of ready-made that everyday objects exhibited in an odd way in a gallery. These early fine art cases highly influenced to furniture design in the second half of the twentieth century. The use of objects in contemporary furniture is closely related to the emergence of Pop Art in the late 1950s and that of Postmodernism. After the 1970s the use of found objects were frequently utilized in furniture design of all over the countries. As an ecological issue became a new consideration to furniture designers, found objects also gave a chance to use recycled materials. Even in studio furniture area which is considered wood as a major material at the early stage, many studio furniture designers began to adapt found objects in their designs as a new source of Inspiration after the 1970s. This study explored various examples of found objects in furniture design and examined the meaning of the use in different designers and regions.

Wood-plastic composites (WPCs) composed of mainly wood flour and thermoplastics have attracted considerable attentions due to advantages of cost effectiveness, high durability, and microbial resistance. However, relatively poor fire resistance of WPCs from low thermal stability of wood and plastics prevents further uses. This study investigated the effect of expandable graphite (EG) and aluminium hydroxide (AH)/magnesium hydroxide (MH) on the properties of WPCs. The combined incorporation of both EG and metal hydroxide (i.e., AH or MH) into formulations leads to higher flexural modulus of filled composites compared to neat PP and WPC. In thermal properties, EG played an important role in improving thermal stability of filled composites by suppressing thermal decompositions of wood and PP. Moreover, EG showed better water absorption features. From this research, it can be said that EG and metal hydroxides have potentials as effective reinforcement, flame retardant, and moisture barrier.

Wood-inorganic material composite (WIC) was prepared by impregnating wood with copper sulfate ($CuSO_4\;5H_2O$) solution and by immersed wood in sodium carbonate($Na_2CO_3$) solution in order to introduce insoluble copper compounds {copper carbonate hydroxide, $CuCO_3\;Cu(OH)_2$} into the wood to give fungicidal effects in treated-wood. The weight percent gains (WPGs) of treated wood reached maximum value by impregnation of 20% copper sulfate solution and immersion in about 15% sodium carbonate solution for 24 hrs. Inorganic substances were present mainly in the lumina and cross-field pitting of tracheides. These substances were proved to be the insoluble copper carbonate hydroxide against water by the energy dispersive X-ray analyzer in conjunction with a scanning electron microscope (SEM-EDXA). The treated specimens showed high preservative effectiveness because the weight losses were hardly occurred by the fungi degradation test.

In this study, the coating properties and surface performance of exotic cherry wood (Prunus serotina) were estimated, reviewing color difference, hardness and abrasion resistibility in order to evaluate probability as construction interior members such as wall and floor. The reduction effect of color difference was represented in the order of water soluble color stain, water soluble transparent stain, and non-coated lumber. However, the tendency of distinct difference according to wood grain pattern was not found. The wavy grain lumber showed better properties in hardness and resistance to abrasion than quarter grain. In conclusion, it was supposed that the application of wavy grain lumber in wall and floor as interior materials would be acceptable in practicality.

Environmentally-friendly polymer composite films were manufactured from cellulose acetate (CA) and polyethylene (PE). To investigate the optimum manufacturing conditions for the composite, various tests such as thermal analysis, surface observation, IR spectra analysis, and elongation ratio of polymer composite films were carried out. The mixing ratio of each element and manufacture condition was found to be very important for the best goods.
