They appear connected with peculiarity of ages. To summarize changes of themes by periods is like this ; First in 1930 s, the time of loss of state power, the main themes are directly related to confirmation of the national spirit. Though the works reveal lyricism indicatively, they represent baffle ment and response to the age, figure a sound historical sense of fighting against reality under the Japanese suppression through the national poetic form. Second in 1950 s∼1960 s, the time of confusion and convulsion, the works show concentratively the recognition about overcoming national division. They accept positively the spirit of the age and social phenomena, describe circumstantial perception and realistic self, change and receive the original traditional spirit of sijosi seeking after features anew, Third in 1970 s, the time of growth and discords, the various subject awareness is emerged. Main currents are by order human understanding and the spirit of investigation, retrospection and natural lyricism, which construct multistory world of poetic sentiment. Poetry sublimes several subjects of poetic creation, which shows that the domain of poetry has set in the horizontal extension and the vertical intension. Lastly in 1980 s, the time of frustration and conquest, human understanding and the spirit of investigation are main streams, which have philosophical inclination internalized poetic awareness. In addition poets have so mature senses that they deposit the lyric ultimate on human understabding and its shaping, portray the superior poetic world that approaches a vivid living dimension, After 1980 s, then, the poetic eagerness of sijosi would be concentrated on the spirit of investigation for humane life formed harmoniously individual life with general life upon dissolution of both nation`s historical understanding and contradictory structure of reality. Thereupon, it is evident that sijosi as the national literature will make good position by revealing the vivid tone impressively.
