Written in the Heian period, Shinsenjikyo was the first radical categorized ancient dictionary in Japan to overhaul the radicals of Han characters. Domestic scholars got new progress in various aspects of its research. However, they have neglected the radical research of Shinsenjikyo, and there was a lack of discussion on the source of its new radicals and the basis for transforming them. First, this article attempts to discuss the radical reform method of the book. Shinsenjikyo has made various transformations and adjustments to radicals, including changing the arrangement of radicals, adding new radicals, reducing the number of radicals, and readjusting the returned characters. Next, this article discusses the strengths and weaknesses of the Shinsenjikyo in the treatment of radicals. Through these discussions, we can see the differences between Chinese and Japanese ancient dictionaries and it will also help us have a clearer understanding of their relationships and characteristics.

본 논문은 『玄應音義』를 중심으로 『新撰字鏡』의 문헌 인용 양상을 고찰하였다. 『字鏡』의 『玄應音義』 인용 양상을 보면, 표제자의 선정, 표제자 표음, 자의 및 예증, 이체자 정보 등 내용 구성면에서 폭넓게 『玄應音義』를 활용하고 있는데, 때로는 『玄 應音義』만으로, 때로는 『玉篇』이나 『切韻』 등 다른 문헌의 정보를 활용해 『玄應音義』의 부족한 점을 보충하여 사서로서의 가치와 효용성을 높였다. 그러나 인용 출처를 밝히지 않아 문헌 인용 관계가 명확하지 않은 점이나, 체제가 엄정하지 못하고 오류가 많다는 것은 이 책이 가진 한계이다. 따라서 광범위하고 정확한 문헌 인용 관계 연구와 석문의 교감을 통해 이 책이 가진 한자학·문헌학 가치를 재조명해야 할 필요 가 있다.

In the abstract, I concretelyexamined a book called 'shinsenjikyo' that introduces various ways to account for 'gujinzi'. Furthermore, from a viewpoint of graphology, I investigated if the explanations in the annotation of the book are about 'gujinzi' that obviously showthe relation of succession in the course of creating a character, atitle letter for searchingthe dictionary of Chinese characters, Chinese characters that arecurrently being widely used, or variants of Chinese characters. Consequently, it was difficult to find 'gujinzi' that obviously showthe relation of succession in the course of forming a character. However, as for Chinese characters that are currentlywidely used, commentaries on 'gujinzi' are quite correct. There are several approachesin identifying the gujinzi relation in characters.To account for the title character, he uses the 'guzi' of the title character or the 'jinzi' of the title character or the 'guzi' and 'jinzi' of the title character. All the three ways shows that the title character and the suggested 'guzi' or 'jinzi' have the same meaning or are substituted or divided characters or are 'gujnzi' that apparently show the relation of succession in the course of forming a character. Accordingly, all the characters are correlatedand were actively used in the past. In conclusion, because the words of 'gu' and 'jin' are used, there was confusion between 'gujinzi' that account for 'guzi' with characters being used currently and widely and 'guzinzi' that means the succession relation in the course of forming a character. However, 'Shochu' seems to be successful in conveying to readers a broad meaning of 'gujinzi' relation that exists in certain Chinese characters.
