Abstract
Reflecting the idea of benevolent royal government of King Jeongjo(鼎俎), the Buyongji(芙蓉池) and Juhamru(宙合樓) of Changdeokgung(昌德宮) are the traditional Korean architecture to represent the Joseon(朝鮮) period. The purposes of this study were to investigate how the Likiron(理氣論), one of the foremost theories of Joseon Confucianism, was applied to the principle of space composition by analyzing Buyongji and Juhamru with Jung's analytical psychology and to provide basic data to utilize the results in modem space planning. The research findings indicate that Buyongji is the space of Ki(氣) to reflect the reality, corresponds to conscious, and represents the Joseon land and people including Chiljeong(七情) And Juhamru is the space of Li(理) with the ideal of benevolent royal government inherited in it and represents unconscious. It also has each building placed which contained the nature of Sadan(四端) along with Gyujanggak and Jewolgwangpunggwak(齊月光風觀) to represent "Self Archetype" that's the core of human mind. Each representing Ki and Li, Buyongji and Juhamru must have worked as a major composition principle of Likilwonronjeokilwonron(理氣二元論的一元論) that could simultaneously satisfy the practice philosophy of reality and ideal among Likiron.
