This DB contains systematic information about Yu Kil-chun's production, collection, and Yu Kil-chun related materials. Yu Kil - chun 's related data are 127 records in The Works of Yu Kil-chun published in 1971 and 2,000 records of Yu Kil - chun' s newly discovered materials. The types of data were classified into three categories: manuscripts, letters, and collection books. The manuscripts refers to the manuscripts written by Yu Kil-chun, mainly the reform-oriented manuscripts, a history of the deceased, poetry, essays, drafts of applications and petitions, and official documents. The letters mean letters, invitations, and invitations received and sent by Yu Kil - chun. The book is a collection of books, magazines, etc. owned by Yu Kil-chun. The manuscripts and letters consist of a single table because of the similarity of the information fields, and the collection books are composed of separate tables because they provide bibliographic and cover image information simply. The table containing the manuscripts and letter information was called 'Yu Kil-chun's Document' and the table containing the information about the collection book was called 'Yu Kil-chun Collection Book'. The information of each table was written in Korean. However, in the case that the meaning does not pass through the Korean language, the Korean word is pronounced in the index word instead of the original text as it is. 'Yu Kil-chun Document' table search can search the entire information through the full search. The detailed search is designed to be searchable by limiting the categories to document group (manuscript, letter), classification (field classification), and headingword 1 (field sub-data group). Classification according to the contents of the document can be confirmed through classification, headword 1, and headword 2. Classification is the area where Yu Kil-chun was active and classified as agricultural, commerce, mining, etc. Heading 1 is a sequencing of data groups based on subjects belonging to sub-areas rather than categories. Heading 1 explained the relation of data belonging to heading 1 in conjunction with releasing series. Heading 2 is intended to categorize things that are difficult to put together as a single topic because many of the related stories come together in the nature of personal documents. Therefore, there is often no information in heading 2. Information on each item includes basic bibliographies, information on the sent and received, the language, the date, and the status of the data. The date was limited to cases explicitly stated in the data, and the timing when it was written was unclear but only in the "Estimated timing" field for the estimable data. The affiliated description created in conjunction with heading 1 collects documents of the same subject and integrates them. Therefore, if the headword 1 covers three or more identical data groups, affiliated description was made. However, in case there is no contents to explain, affiliated description was not made. The 'Yu Kil-chun Collection Book' table contains bibliographic information about the collection books. The title and table of contents of the collection book can be confirmed by opening the file by clicking the file name. 'Yu Kil-chun Document' is not easy to distinguish through classification and headwords because the format of data is very diverse and its content is broad in the fields of economy, education, politics, and society. Therefore, in order to improve the accuracy of retrieval, it is necessary to use the headword 1 as a reference and to combine searching of the contents of individual description.
1. Provision of basic data to expand the horizon of 'Korean Modernity' research The electronic textualization of Yu Kil - chun 's data has a very important meaning in activating the research on the linguistic expression style from the viewpoint of 'the way in which the modern recreates and re - arranges the tradition'.

Increase the objectivity of text interpretation by explanation data and affiliated description The DB construction of historical data has greatly expanded the study of the general humanities as well as the history by providing basic information of text interpretation to the general public. In the process, however, there are cases in which the objectivity and scientific character of text interpretation are shaken as a result of not providing systematically data for 'distance' and 'appropriation' of text. Therefore, this study intends to contribute to improve the objectivity and scientific characters of text interpretation by providing the affiliated description as well as the description of the individual data to the public. In addition, it can be applied to various education for interpretation of modern text by presenting a new data model of description data and affiliated description.
