We live in the age of machine civilization and information with computer and inform media. Therefore, we should admit Western postmodernism in our literature. Though it was occured in Western Europe, we can`t deny this trend of thought with only the closing and sentimental response. Though the phenomena of our social development are different from Western Europe`s in the age, in the course of industrialization and urbanization, these phenomena are streaming in the likely toward like Western Europe`s. In this point of view, this paper tried to compared Western postmodernism with our postmodernism and analyzed them with actual works, showed phases which postmodernism have been accepted in our society and some characteristics whichit have been appeared in accepted course of it, with the theory of method. The phases and characteristics are the followings : The first, used the parady for the imitating and satirizing the established traditional style with the basing the established works of traditional style, society and world. The second, realised the restoration of humanity against the alienation of human, anti-elitism, subjective creativility and the re -establishment of new style in art. The third, imagined the external appearance and organized the internal appearance with the material for the usual life in the dubious, partial society. The fourth, removed the difference between high-literature and low literature, presenting the uncertain partial reality with the fiction and imagination of the description method in novel, The fifth, expanded the meaning of language not in the method of metaphor but in the method of metonymy, and, in the same time, described with a rhetorical device, Through these various methods, post modernism in Korea have re-organized fittingly Western postmodernism in Korean society. However, in the accepted course of postmodernism, we could have discovered some problems in Korean modern poetry, The established traditional style and the deconstruction of tradition in Korean society have streamed in the way of the extreme experiment in Korean modern poetry, Western postmodernism have destroyed traditions language in Korean society grammar-structure in the part of syntax, therefore, have defamed the value of languageart. On the other hand, the sounds which writers have criticized their society and accused the problem of their society, could have produced another ideology. In fact, the accepted course of Western postmodernism have implied some nagative phases, but the acceptance of Western postmodernism in the part of Korean modern poetry must have been an active method we have exploited and created our actuality in. The characteristics of postmodernism which korean modern poetry have implied, appear in the toward of deconstruction of spirit popularity and commerciality of literature, the phenomenon of iconoclasm in the part of art in the traditional, institutional territory. Finally, in the international exchanging, in the end of the 20 th century, postmodernism which have been flowed into our society. Though it is the foreign trend of thought, it have been recontroled and accepted fittingly in our society, for a society has a consciousness which the society tries to recontrol the trend of thought with, when the trend of thought is flowed into a society. Accordingly, I think we must develop Western postmodernism as Korean postmodernism fitting in Korean society with the subjective point of view.
