T’ien-t’ai Thinker in Gae-Seong[開城] of Koryo Period: Uichon(義天) and his disciples

In this paper I would study Uichon(義天)’ thought and his disciples as T’ien-t’ai thinker in Gae-seong of Koryo period. To study this subject, I say that Gae-seong of Koryo period is the center of buddhist culture in first chapter. And I say the development of Koryo period’ T’ien-t’ai thought in second chapter. In three chapter I say the change of Uichon(義天)’ thought and the activity of his disciples. Uichon(義天)’ thought is divided into the first term and the latter term. In the first term he depends on Ch’eng-kuan(澄觀)’ thought, and in the latter term he follows Tsung-mi(宗密) and Wonhyo(元曉)’ thought. And the first term of thought is succeeded to T’ien-t’ai tsung(天台宗) and Hua-yen tsung(華嚴宗). The latter term of thought is succecded to Gyeung(戒膺), but the influence of Gyeung(戒膺) is slight.
