When Myeonam(면암) Choi Ik-hyeon(최익현) died in Tsushima in November 1906, Ugo Lee Tae-ro began to collect materials related to Myeonam. The materials were compiled in two works 『Myeonam-seonsaeng-munjip-cho(면암선생문집초)』·『Myeonamjip-cho-bujegaseo(면암집초부제가서)』, which are released along with this study. The former work consists of Myeonam's writings that are already available to the public. The latter, however, includes hitherto unknown poetry and other materials that are related to Myeonam. In particular, the latter includes five pieces of gasa (narrative poem) that were written by a number of people after Myeonam's death in Tsushima. The poems were written in Gaehwa-gasa(개화가사) style in which 4.4 meter is the basic form and two phase form one stanza. The poems praise Myeonam's loyalty and mourn over his death. The collection also includes a handwritten version of 〈Maegukgyeongchukga(매국경축가)〉. The version is different from the one published in the newspaper as it was revised by Ugo or some other person. The version published in the newspaper was composed of five stanza whereas the Ugo version has one more stanza at the end of the poem. There is no change in overall meaning of the poem. However, the new stanza changes the tone of the work and strengthens its meaning.
