Objectives : While the original version of 『Eoyakwonbang』 does not exist, its contents have been introduced in several studies. The existing editions are the Joseon versions 『SinganHyeminEoyakwonbang』(Eulhaeja edition) and 『GyesaSinganHyeminEoyakwonbang』(Gapjinja edition), and a Japanese version, 『GyesaSinganHyeminEoyakwonbang』(Gwanjeong edition). In a recent research, it has been discovered that there is a fourth edition of the book, 『SinganHyeminEoyakwonbang』(Jeonggadang edition), in the Japanese Parliament Library collection. Methods : Contents of the chapter on pediatric diseases were compared among the four editions to clarify their relation with each other. Results : Based on the organization of the chapter, formula names in the list and body, explanatory methods of the formulas, application, formula construction and methods of application, we found that there were great similarities between Eulhaeja edition and Jeonggadang edition, and between Gapjinja edition and Gwanjeong edition. Conclusions : 1. Jeonggadang edition is similar to Eulhaeja edition in contents and form. 2. Although the exact publication date of Jeonggadang edition is unknown, based on the fact that it was mostly circulated in the Qing period, it can be assumed to have been published after the Eulhaeja edition which was published in the 15th century. 3. Gapjinja edition was published in the 16th century and shares little similarity in form, organization and contents with Eulhaeja edition, indicating that a different version was used as the original script. 4. Gwanjeong edition was published in the 18th century, and is very similar in form, organization and contents with Gapjinja edition, repeating the same errors made in the Gapjinja edition. This indicate that Gapjinja edition was the mother script of Gwanjeong edition.

Among about 500,000 characters in metal types in National Museum of Korea, this study conducts a statistical analysis of 62 metal types from the early Joseon Dynasty, including 33 gabinja (甲寅字) types and 29 eulhaeja (乙亥字) Hangeul types by examining the shape, measuring the specific gravity, and identifying the components based on previously-studied Joseon metal types. Among them, 33 gabinja types and 24 eulhaeja types were made of two-component bronze (copper and tin) (Group A), and four eulhaeja types were produced with three-component bronze (copper, tin and lead). (Group B), and one eulhaeja type was created with two-component bronze (copper and tin) with a high tin content (Group C). By comparing with imjinja (壬辰字) types of the late Joseon Dynasty based on multiple statistical analyses of type components, this study confirms that late-Joseon types have low copper content and high zinc and lead content, and therefore it may be possible to distinguish between the types of early and late Joseon Dynasty.

This study examined the characteristics of Buddhist books printed using metal type during the Joseon Dynasty period from a bibliographical perspective. It was found that there are 36 kinds of Buddhist books published using metal type during the Joseon Dynasty period that currently exist. In terms of the types used for publication, there were 9 kinds of printed editions by Gapinja, 13 kinds of printed editions by Eulhaeja, 2 kinds of printed editions by Jeongchukja, 3 kinds of printed editions by Eulyuja and 9 kinds of printed editions by Jeonsaja. Among them, The Buddhist books printed using Eulhaeja were 36 % of total with the highest quantity of 13 kinds. In terms of periods of publication, it was found that 27 kinds and 9 kinds of Buddhists books were published respectively in the first and latter parts of Joseon Dynasty periods. Among them, there were 19 kinds of metal type book editions published during the King Sejo period that occupied 70% of total. It appears that such phenomenon was a result of King Sejo's abnormal enthronement and Buddhism-friendly tendency.

After replicating 10 bronze types such as Gyemija, Gyeongjaja, Eulhaeja, etc. before the Imjin war, we studied the change of microstructure from each casting process, method, and alloy ratio by Gyechukja replicated from "Donggukyeojiseungnam". We selected the average of compositions of Eulhaeja in the National Museum of Korea as the standard(Cu 86.7%, Sn: 9.7%, Pb: 2.3%) of bronze types, so we decided on the alloy's composition of Cu 87%, Sn 15%, Pb 8% added to 5% Sn and Pb contents because of evaporating the Sn and the Pb. Before replicating major metal types, we made master-alloy first, melting it again, and then replicated metal types. The composition of the 1'st replicated Gyechukja showed the range of Cu 85.81~87.63%, Sn 9.27~10.51%, Pb 3.05~3.19%. The 2'nd replicated Gyechukja made using the branch metal left after casting the 1st replica. The 2nd replicated Gyechukja showed the composition range of Cu 87.21~88.09%, Sn 9.06~9.36%, Pb 2.80~3.05%. This result decreases a little contents of Sn and Pb as compared with metal types of the 1st replica. However, it's almost the same as the Eulhaeja's average composition ratio in the National Museum of Korea. As a result of observing the microstructure of restored Gyechukja, it showed the dendrite structure of the typical casting structure and the segregation of Pb. There is no big difference of microstructure between the 1st and the 2nd restored metal types, even though the 2nd restored types partially decreases the eutectoid region in comparison with the 1st types. The systematic and scientific restoration experiment of metal types using Joseon period will be showed the casting method and alloy ratio, and this will be of great help to the study of restoration metal types in the future.

In this article the purpose of the study on Eulhae metal type(乙亥字) "Huangjenaegyeongsomun(黃帝內經素問)" is to ascertain the era of that publication according to recent investigation and find the properties of that book through comparision with other "Huangjenaegyeongsomun(黃帝內經素問)" published in ancient Korea, Choseon Dynasty. Because we are not yet secure more various Eulhae metal type(乙亥字) books and collaterally printed books, and there would be more unknown Eulhae metal type(乙亥字) "Huangjenaegyeongsomun(黃帝內經素問)" in Korea or abroad, so this study focuses on investigation of publish are only based on the record in that book, and comparision with the context of other Korea-published "Huangjenaegyeongsomun(黃帝內經素問)". As a result Eulhae metal type(乙亥字) "Huangjenaegyeongsomun(黃帝內經素問)" was published in Myeongjong era about 1554-1557, was the very original book of exiting Naeeuwon(內醫院) type "Huangjenaegyeongsomun(黃帝內經素問)". This Publication of this book published with Eulhae metal type(乙亥字) "Huangjenaegyeongyeongchu(黃帝內經靈樞)" at the same period explains that at that time Choseon Dynasty lay emphasis on promoting Medicine and teach "Huangjenaegyeong(黃帝內經)".

This article investigate the xylographica of Myopopyunhwakyung printed by movable type in the Chosun Dynasty in three aspects. It analyze： i ) the spread to the East Asia of Myopopyunhwakyung and its distribution； ii ) the distribution of Myopopyunhwakyung printed by movable type in the Chosun Dynasty； iii) the bibliographical characteristic of each edition. There are many editions of Myopopyunhwakyung, it is important to divide its circle of editions and to suggest the value, Myopopyunhwakyung was printed and distributed by movable type of Chojukapinja and Eulhaeja style in the Sejong and Sejo reign. Its reprinted edition was distributed from the Sungjong reign to the Youngjo reign. the bibliographic characteristic of each edition of Myopopyunhwakyung is various and peculia in the temple calligraphic style, an illustration of Buddha preaching, and the list of participants and donors.
