As a detailed process for the development of new wooden furniture design that is to be used in elderly group homes, this study measured and analyzed physical and visual durability of joint techniques, one of the essential manufacturing techniques. By selecting a total of 4 joint techniques, an experiment to measure a compressive strength was conducted and targeting a group of 50 elderly people, a survey on visual durability and preference of visual aesthetics was carried on. As a result of closely analyzing the experiment of measuring compressive strength and the preference survey, 'mitre joint technique' was found to be the most suitable in manufacturing wooden furniture and through follow-up studies, the result of this study will be applied in the development of wooden furniture design for elderly group homes.

This study mainly inquired characteristics and changes of 'Chang-aelgool' through 38 cases(with 161 Ssang-chang) of annex and pavillion buildings in Yeong-nam region which are built during the Chosun dynasty. The method of inquiry included actual survey of windows along with bibliographical research, and the results are as below. First, through the discovery of the term 'Chang-aelgool' as an indication of the window-forming frame in 'YeongGeonUiGwe'(1680 A.D), it is apparent that the term 'Chang-aelgool' was widely used in Korea from the late 17th century. Second, the 'Chang-aelgool' of study objects are classified into 4 categories. Type I and II are comprised of mitre-joints which cover the 4 corners of 'Chang-aelgool' and mainly used in building annex and pavillion buildings during the early period of the Chosun dynasty. Type III was widely used during the early and middle period of the Chosun dynasty and drastically dropped in number during the late period of the dynasty. Type IV is comprised of mitre-joint of the upper-half, tenon-jointing of the lower-half and widely used in annex and pavillion building during the late period of the Chosun dynasty. Third, the form of 'Chang-aelgool' has changed from rectangular form with longer width during the early period of Chosun dynasty to square form during the middle period and eventually ended up as a rectangular form with longer height during the late period of the dynasty. Fourth, it is considered that while mullion which is located in the center of 'Chang-aelgool' was mainly used around the main floored room during the early period of the Chosun dynasty, became commonly used in main floored room and 'ondol' rooms during the middle period and drastically dropped in number from then and ended up being not in use after the mid 18th century.
