Dongshi (東詩) is called Gwacheshi (科体詩), Haengshi (行詩), Gongryeongshi (功令詩), or Donginshi (東人詩). It is the unique poem style that was originally created as an answer for the National Test [Gwageo] but soon used as a concept encompassing Gwachesh (科體詩). This dissertation aims to examine Muninpyeyuga (門人廢蓼莪), a Dongshi by Gosan Yun Seondo (1587-1671), a representative writer of Shijo Shiga Dongshi literature in the first half of the 17th century.
To this end, the researcher divided works that accepted ｢Yuga｣in『Shigyeong (The Book of Odes, 詩經)』 published in the literature anthologies according to the times they were written such as the first half and the second half of Joseon Dynasty. And then the acceptance pattern of that period was reviewed. Next, it was reviewed how 'Yuga' in "Shigyeong" was implemented in Hanshi by Yun Seondo through the expression technique of 『Sikyung』realized in his work and the antithesis technique of Hanshi. In particular, it was analyzed how the old story of "Pyeyuga' of Wangbu reflected in his Dongshi was shaped as a poem in his Dongshi and confimred the degree with the content analysis. Through this, the internal and external characteristics of the work were synthesized and summarized, and the significance of Yun Seon-do's works in the history of filial piety literature was demonstrated.
