The expected effects of this study are as follows. First of all, this study is characterized by a work that encompasses pre-modern and modern times. In particular, the end of the 19th century, which shifted from pre-modern to modern times, is a transitional period in which modern languages were formed from the perspective of Korean and Japanese research. This study is expected to greatly contribute to the activation of research related to the formation of Korean or Tokyo languages during the age of enlightenment, which has been at the blind spot of the study so far. Secondly, as a detail of the study, the literatures in which Korean is written in Kana can be used for phonological research such as the process of change in Korean pronunciation as 'foreign language transcription data' and is considered to provide a strong basis for estimating the inflow process of Japanese Kanji during the age of enlightenment. Thirdly, the production of these textbooks is closely related to the history of Korea-Japan relationships after modern times. In particular, the existence of multilingual textbooks such as Korean- Chinese-Japanese or Korean-Chinese-Japanese-Russian before and after the Sino-Japanese War and the Russian-Japanese War, and Korean language textbooks published by officials of the Seoul-Busan Railway, can be expected a new form of interdisciplinary research to combine the study of language and modern history. Finally, the textbooks surveyed contain a wealth of Korean short poems, proverbs, and folk words that were popular at the time, so they are expected to be used for research related to various fields of humanities such as Korean literature, folklore, and history of Korean education.
