This study is meaningful because it accessed Baekseok`s children`s literature based on the information about him which had not been discussed in existing studies on his children`s literature. First, the study examined the time when Baekseok became involved in children`s literature. It found he had been involved in children`s literature by translating foreign literature even before he published reviews or his creative works of children`s literature. That is, he first became involved in children`s literature by publishing his translation of Gorky`s "The Theory of Children`s Literature-Beginning" in the literary magazine, Joseon Munhak in March 1954. The reason Baekseok, as a professor in the department of foreign literature, translated children`s literature is supposedly attributed to the demand initiated in North Korean literary circles in 1953 that writers outside of the department of children`s literature be involved in children`s literature. Next, the study looked into newly discovered fairy-tale poems. The examination of North Korea`s information on Baekseok confirmed that he had already published two fairy-tale poems, "Magpie and Azure-winged Magpie" and "Four Jige Crab Brothers" in January 1956 before the publication of "Four Hermit Crab Brothers." "Four Hermit Crab Brothers" which is the title poem of a collection of fairy-tale poems and "Four Jige Crab Brothers", the original work of "Four Hermit Crab Brothers", are starkly different in terms of title, development and the use of poetic words. Along with this, the study also examined another work "Magpie and Azure-winged Magpie." Then, it confirmed that the characteristics of "Four Hermit Crab Brothers" also appeared in his previous work "Magpie and Azure-winged Magpie." Lastly, the study found that Baekseok published four children`s verses right before he stopped writing creatively. These works are different from his previous works in that they openly admire the communist system.
