This analytical study was carried out to make quality and productivity up in designing the frame-type furniture with semi-rigid joint by understanding the mechanical and structural behavior of the joint and by evaluating the validity of application of the time-saving Finite Element Method to its structural analysis. Slope deflection equation for rigid joint was modified to describe the moment-rotation behavior of semi-rigid joint and the joint stiffness factor(Z) could be calculated to lessen the experimental expense. It was proved that Finite Element Analysis with imaginary elements having equivalent MOE to the semi-rigid joint could be the alternative method for the structural analysis of the frame-type furniture, comparing the internal rotation of the 2-dimensional beam-to-column model with two-pin(wooden dowel) from the finite element method with other available theoretical and experimental rotation value.

A joint brand of furniture companies named Gaboro has been officially launched in the form of a juridical foundation. It was invested by Seoul City and the union members for regenerating the furniture companies in Seoul on August 1, 2003. However, Gaboro still has a few problems to overcome for successful business from joint marketing. Firstly, Gaboro must create a R&D post in order to lead the member companies through consistent production of furniture in addition to engraving its brand. Secondly, the head office of Gaboro must be authorized to prevent each union member from manufacturing the furniture products not well suited to the fresh brand. In addition, the member companies justly need to regulate the product items, and simultaneously to accept the new image concepts. Lastly, Gaboro needs to launch unique items to discriminate its design from other competitive companies.

Under the paradigm of 'Eco', the core of sustainability management, this study aims to establish both domestic and international markets and secure competitiveness in the global markets through the development of children's furniture composed of recycled and unharmful materials. Currently, in Europe and in the Western regions, the concepts of 'eco-friendly', 'children', and 'DIY' are well-placed in the daily lives of the people. On the other hand, compared to the domestic demand for eco-friendly children's furniture, the essential approach and the qualitative improvements about the subject are being slowly progressed. Particularly, the process of applying eco-friendly materials and finishing materials to the children's furnitures are mostly in a non-existent state. Thus, in this study, simple application of basic eco-friendly materials such as natural woods or imitation of overseas furniture designs were avoided to create transformable eco-friendly one-touch DIY children's furniture for children's growth and development through the application of eco-friendly processes of technology, design, and other stages of the development process. In other words, under the big category of eco-friendly children's furniture, the furniture was developed through an environmentally-friendly process of universal design that is suitable for children of all ages, and thus, ultimately maximizing the economical effective value and reducing consumption of resources and environmental pollutions.

This study explored the development of wood furniture made of aged Castanea crenata Sieb. et Zucc, which has been largely planted in the southern area since 1960s and has hardly been used as furniture materials. First, the physical properties of the chestnut wood including specific gravity, stiffness, and shrinkage were compared with Zelkova serrata, Acer palmatum Thunb., Fagus crenata var. multinevis, Quercus, Tagayasan, Prunus serrulata var. spontanea, Juglans sinenis, Pteronrpus santalinus, Diospyros ebenum, and Fraxinus rhynchophylla, which have largely been used in manufacturing furniture. The chestnut wood had appropliate physical properties for wood furniture like other furniture woods. A piece of small table 50 cm in width, 50 cm in length and 60 cm in height by the chestnut tree was created for a current interior space. Since the diameter of the chestnut tree planted since 1960s is below around 30 cm, the top plate of the table had to be put together by an end-joint technique using a small strip. Finally, it is expected that this study will create a greate motivation for furniture designers, furniture studios and furniture companies in Korea to use the woods from the aged chestnut tree in developing furniture in the future.

Recently, interest in wooden construction have been growing by increasing needs and demands for eco-friendly and traditional wooden building(Hanok). Especially, Hanok has the technical development in manufacturing the mortise-tenon joint without fasteners(precut), so it could be called to modernization, industrialization and popularization. But the structural design and analysis of the structure were not regulated and had the difficulty to consider the variation of wooden member and to conduct the difficulty in the structural analysis and the design of the joint. In this study, the stiffness ratio of wooden mortise and tenon joint was evaluated according to the vertical loading, lintel and loading speed. The joint was distinguished in semi-rigid joint regardless of their factors. The stiffness ratio was 0.40 in vertical loading, 0.50 without vertical loading and 0.44 in horizontal loading with high speed. This study would be utilized to the structural analysis and design with structural analysis and design program.

The joinery technique, as one of manufacturing techniques for the wooden furniture, influences the production process, the economic efficiency, and the diversification of design. Especially, the usage of machine tools can determine how much the students can enhance their design expression capabilities during the practice class in furniture design courses of domestic universities, in accordance with whether to utilize the machine tools or not, and how much and frequent to use the machine tools. The study proved that the joinery techniques, based on the high-tech machine, has more efficiencies in the various aspects, including the easiness to manufacture the products, and the diversity of design than the joinery technique, based on the handcraft-only. As the ground of this, this study estimated the time to produce the wooden furniture by machine tools and by handcraft-only, each. Also, this study show the comparison of the features of three different joinery techniques. On the basis of this comparison, this study made the conclusion that the machine-based joinery technique, which is used in the practice class, is the best method to bring the best results in manufacturing the wooden furniture.

Modified poplar has emerged as a potential raw material for furniture production. Lack of specific modified poplar strength information; however, restricts applications in the furniture industry especially as related to strength in corner-joints. Optimization of strength in L-shaped corner dowel modified poplar joints under compression loads utilizing finite element analysis (FEA) by Taguchi method with the focus of this study. Four experiment factors (i.e., Structure Style, Tenon Length, Tenon Diameter, and Tenon Gap), each at three levels, were conducted by adopting a $L_9-3^4$ Taguchi orthodoxy array (OA) to determine the optimal combination of factors and levels for the von Mises stress utilizing ANSYS software. Results of Signal-to-Noise ratio (S/N) analysis and the analysis of variance (ANOVA) revealed the optimal L-shaped corner dowel joint in modified poplar is $45^{\circ}$ Bevel Butt in structure style, 24 mm in tenon length, 6 mm in tenon diameter, and 20 mm in tenon gap. Tenon length and tenon gap are determined to be significant design factors for affecting von Mises Stress. Confirmation tests with optimal levels and experimental test indicated the predicted optimal condition is comparable to the actual experimental optimal condition.
