Abstract
This paper inquires into the changing process of the type of nosing-ornamental termination of projecting members of bracketing like A and B in Fig. 4 in the Tap'o style in Korea. The type of nosing (Figs. 1,2,3) is adopted to the old buildings in the Tap'o style before the middle of the 15th century. From the latter half of the 15 th century to Im-Jin War (1592-98), this type of nosing changes into the new one (Figs. 4, 7, 9, 11). And this type of nosing after Im-Jin War is successively applied to the end of the Yi-Dynasty.
