Media for literature works during Pre-and-Post Korean War were being changed with discontinuance of existing media and birth of new media. In this time, dominant ideology was affected in the field of literature and new discourse, its reproduction, begun to spread. `Si-mun hwak(詩文學)` and `Munyea(文藝)` were published just before the Korean War, and after the Korean war, two media are similar in that they accepted the nationalism ideology throughout the planning of media that is called `War Publications`. Both of them tried to express pure literature works than political works. However, because of the Korean War, they couldn`t but revise the basic strategy of media. They basically edited media with nationalism ideology that is based on anti-communism in order to keep the field of pure literature. Anti-communism was the major discourse of the time of the Korean War and just after the Korean War, and after 1950s, it was continuously reproduced as the major discourse of the circle of literature. In the crisis of nation, `pure` literature based on ideological basis of the right writers broadened the field of its existence throughout the publication of various war-media, its edition and planning. The big historical change, the Korean War, affected on the existing literature media, and consequently it affected on its composing discourse. Various literature media called by nationalism ideology during the Koran War added more strong identified ideology to literature media. The viewpoint of the nationalism based on anti-communism was reflected on composition and planning of literature media in this time. Media editors and writers in this time raised this ideology as sublime ideology throughout the symbol like `star`, `flower`, and `flag`.
