The modern time of Korea has the character which is a modern time of disruption. And Sinsi which appears in the time is the form or genre which shows the character of like this Our modern time very well. Therefore the fact that interpret like this Sinsi in form of `transition period` is cuts Sinsi with the eye of tradition and the eye of the Other(West Europe). And this brings about the result which does to make the actual features and meaning of Sinsi lose simultaneously. And Like this attitude is to make Sinsi with the `ghost` who exist only within the history of literary and to exist only short period. Therefore history of literary of meaning of Sinsi must seek from disruptiveness oneself of our modern time which the Sinsi shows. A external qualities of Sinsi are Crisis of poetry and song, A mixed style of writing Korean with Chinese characters and Agreement of number of sound of correspondence line of each stanza. And It shows a disruptiveness or mixture of tradition and modern time. First, Sinsi leads and the character as modern poetry a duplicity simultaneously the discontinuation which with the tradition which is Crisis of poetry and song is basic distinguishes with tradition of Korean poetry is immanent keeps. And destruction of tradition and succession as duplicity of Sinsi which is a does there to make be could be given role of the bridge meaning which is an existence which does from within the history of literary. To Sinsi with disruptive aspect of our modern time and being new, the will toward is being put in. And the problems of `nations`, `educations`, `enlightenments` two that are being put in the inside moving. Like this aspect from Sinsi inside appears concretely with two kind. It is to a external form and is a duplicity and the internal form and specially disruptiveness of poetic subject. The duplicity of external form disruptive aspect of our modern time, the namely model with becoming enemy, only will be able to emphasize the nation and a tradition reflects a point. And the disruptiveness of internal form is to our modern time and reflects the disruptiveness of modern subject. When trying to synthesize like this points, a meaning of history of literary which Sinsi shows finally does not make be only a possibility of seeking from this duplicity or disruptiveness inside. And we will lead and this there makes be a possibility which we will seek the quality and meaning of Sinsi as of `Korean modern poetry`. Succession and destruction of the tradition which the namely Sinsi shows, disruptiveness oneself which the poetic subject of the new at the time of shows Sinsi `Korean modern poetry` makes be a possibility of seeing in the genre(species) which is unique is from within our history of literary and makes do as a favor is a thing.
