Crafts is like aliving organism that growing up continuously with human history. Craft is a beautiful instrument made by human hand, a creative art and a cultural inheritance of mankind. Craft is an aesthetic of life that is permissed on ‘use’, it’s practice, and a mirror reflecting the epoch as well. It also is cosilience of science, art and life, and a fruit of communication. Woodcraft activities have an inseparable relationship with our life, and it is a field that needs to be continued because of the value of education for the growing students. The interest in woodworking from childhood to old age is rapidly expanding nowadays, therefore this study has been done to provide images to those who are engaged in woodcraft business and also those who are interested in this field. If we look at the use of wood in our daily life, We can classify it into Architecture, Civil engineering, Furniture, Musical Instrument, Packaging, Recreational instrument, Exercise instrument, Stationery, Daily commodity, and Industrial use. Early golf clubs were almost certainly made entirely of wood with the clubhead and shaft being made of different types, glued together and bound in twine. Ash (Fraxinus spp.) and hazel (Corylus avellana) were used for the shaft, while beech (Fagus spp.), blackthorn (Prunus spinosa), pear (Pyrus communis), and apple (Malus Pumila) were popular for the head. In another sports item, the most frequently used species are hardwoods such as ebony (Diospyros ebenum), hicory (Carya spp.), box wood (Buxus sempervirens), beech (Fagus spp.), myall wood (Acacia pendula), mulga (Acacia aneura), cinamon wood (Cinnamomum camphora Sieb.), coach wood (Ceratopetalum apelatum), hinoki (Chamaecyparis obtusa), silver magnolia (Machilus thunbergii), hacverry (Celtis spp.), rose wood (Dalbergia nigra), ebony (Diospyros ebenum), oak (Quercus spp.), cherry (Prunus spp.), beech (Fagus spp.), bamboo (Phyllostachys bambusoides Siebold & Zucc.), walnut (Juglans regia), maple (Acer palmatum Thunb), bubinga (Guibourtia spp.), birch (Betula) and laminated wood.

Aggravation of natural environment, improvements in income, internet diffusion, spread of five-day work a week, and population aging seem very different from each other. However they boil down to consumption. These culture patterns are changing into environment-friendly and productive housing culture. In other words, people might tend to have frequent contacts with not only environment-friendly housing in bustling cities but also woods that is environment friendly materials in their leisure time. In the period of people young and old alike are in favor of woodcrafts, this study was conducted for giving information to who speicalized in woodcrafts. Furthermore, the study shows that other countries also added grain and figure to woodcrafts for visually appealing.

Unutilized wood refer to fuel that have undergone certification procedures using the products specified in Article 2 of the Regulation on Use and Promotion of Forest Biomass Energy Sources. Unutilized wood are by-products other than logs derived from harvesting, species production and deforestation for the purpose of mountain development, and harvesting products from forests. Since these Unutilized wood are pure wood, there is no concern about environmental pollution. According to the Korea Forest Service, the raw materials neglected in the mountains are accumulating 4 million tons annually. These raw materials are not collected properly and are neglected, which become a cause of forest fires and pests. Energy conversion of these abandoned raw materials will not only create new value as renewable energy, but it will also help preserve the environment. This study was made to investigate and report the foreign examples of recycling not used and small diameter log of Ginko biloba L., Zelkova serrata Makino, Castana crenata S. et Z, Cedrela sinensis A. Juss, Tilia amurensis Rupr. which are excellent wooden materials left to be discarded after making traditional furniture.

Wood carving has been extremely widely practiced, but survives much less well than the other main materials, being vulnerable to decay, insect damage, and fire. It therefore forms an important hidden element in the art history of many cultures. Even though wood is less durable than either steel or stone, it has been used for a long time due to its usefulness. Wood has a lot of benefits. So people have used wood for materials in houses, trains, cars, bridges, and simple utilities in their ways according to their own religions, climates, and environment they are living in. Nowadays, there are wood products that are made up for its weaknesses and this has made wood be used in variety fields. Moreover, wood has been widely selected materials for sculptures, interior, and also for architecture thanks to its colors and textures. Wood has helped our life more abundant and beautiful.

This paper describes the relationship between the bending strength properties of sloped fingerjointed woods and the acoustic emissions (AEs) generated during the test. Rhus vernieilIua pieces were cut in sloped-finger types and glued with three kinds of adhesives (polyvinyl acetate, polyvinylacetate and oille urethane resin). The slope ratios of finger joints were 0, 1.0, 1.5, and 2.0. The AE cumulativeevent count and cumulative count were measured during the bending test.<br/> The results were as follows:<br/> The lower the bending strength(load) was, the earlier the generation time of AE event count got and the higher the increasing rate of AE event count became in the sloped finger-jointed specimens bonded with polyvinyl acetate, polyvinyl-acryl acetate and oillc urethane resin adhesives. Therefore, the slope from load-AE cumulative event count curve was very steep.<br/> The patterns of AE event count and count were very similar.<br/> The relationship between the MOR and the AE parameter from load and AE cumulative event count in the early stage of the sloped finger-jointed specimens bonded with polyvinyl acetate, polyvinyl-aeryl and oillc urethane resin adhesives was much greater than that betWeen the MOE and the MOR. Therefore, the AE signals obtained during bending test are useful for estimating the strength of sloped finger-jointed Rhus verniciflua specimens.<br/> Keywords: AE event count, AE count, bending strength properties, sloped finger-joint, kind of adhesive, Rhus verniciflua.<br/>

Nowadays, kitchen are not for the housewives who were independent themselves in the past but for the functional spaces. Kitchen spaces are not only the main function in the residence but also changing spaces which provide the mutual understanding communication between the family members. Although the primary function of the kitchen is food preparation, it is commonly a gathering spot for family and friends, especially if it includes an informal eating area. With so much time spent in the kitchen, and can easily become tired do the decorating scheme. But, for fear of high remodeling costs, it is often unchanged for many years. Surprisingly, there are many changes that can de made to the decorating scheme of a kitchen without either the expense or the inconvenience of remodeling. Between materials on the market, materials for kitchen interior were chosen for this study. Folllowing results came from the materials after combustion. Among boards, MDF showed the highest score in these four categories; residual inflame time, residual glow time, carbonization length, carbonization area. Also, among finishing materials (interior materials), MDF + Poly Coating showed the highest score in those categories. Therefore, it seemed that interior materials need flame retardancy.
