The National Museum of Korea's 'Shinchungmyeong Jochong' is the sole firearm in the country bearing inscriptions written in ink('辛丑改備江華庫藏'). Thanks to this written record, it is possible to determine where this firearm was stored and to make an estimate of the time when it was stored. Additionally, it is a valuable artifact that has been exceptionally well preserved and has an artistic design. However, research into the operational period, form, and structural characteristics of this firearm has been limited to date. This study aimed to shed light on the operational period, form, and structural features of the 'Shinchukmyeong Jochong.' To achieve this, the specifications and structural characteristics of the firearm were examined, and comparisons were made with 17 other extant firearms and their attributes. The results confirmed that the 'Shinchungmyeong Jochong' is a representative example of the typical firearms of the Joseon Dynasty. Next, the timing, background, and production subject of the Ganghwado containment of the Jochong were tracked based on letters found with the Jochong. The investigation revealed an entry in the 'Records of King Jeongjo'(『正祖實錄』) indicating that a significant amount of military supplies, including firearms, were stored on Ganghwado in December of the 5th year of Shinchung(1781). The decision to store these materials in Ganghwado Island may have been due to the perception of the Joseon decision-makers, who strategically valued Ganghwado Island, and the relocation of 'Tongaoyeong'(統禦營) and the integration with 'Jinmuyeong'(鎭撫營). After acquisition, it is presumed that the firearm was operated at locations like 'Jinmuyeong'(鎭撫營). The firearm's production is presumed to have been associated associated with institutions such as 'Gungisi'(軍器寺). In conclusion, the 'Shinchungmyeong Jochong' exemplifies a typical firearm of the Joseon Dynasty, and it is likely that it was stored on Ganghwado in December of 1781. Its production is believed to have been related to institutions such as 'Gungisi'. Following its acquisition, it is presumed that the firearm was operated at locations including 'Jinmuyeong'.

When investigating old, printed documents, determining whether a work is printed on a woodblock or using a movable metal type is crucial. It is because the history of printing in Korea and across the world relies on determining the relevant printing invention used and the time of use of the movable metal type. Deciphering details from woodblock and metal prints requires various kinds of information regarding the imprint and the work's printing background, such as information on the characters in the printed document, the outline of the pages, the type of ink used, the production period of the ink, and the production period of the Korean paper. Analyzing such information can generally reveal the production period and the methods used on the old document. However, as such information is not documented systematically, relying on the researcher's judgment based on their experience and perception becomes inevitable. This study conducted an experimental investigation of the printing characteristics of woodblock prints using a replicated woodblock of the Wanpanbon edition of the Shimcheongjeon. Subsequently, the various phenomena and characteristics appearing on the woodblock prints were documented for future reference to determine the printing method of old documents. Finally, woodblock novels without an imprint may be used as a reference to estimate the printing dates by determining the degree of wear on the woodblock.

This study was conducted to examine the chronology of Taesil Seokham(Taesil Stone Boxes) stored in Taesil of the Joseon Palace and classify the styles to discuss how these boxes have developed. By doing so, this study defined the archaeological styles of taesil seokhams in the chronological order. Although taesil seokhams are placed when taesil are first created, they do not have any texts engraved on them and it is difficult to gain information only from examining taesil seokham. However, Taejiseok(memorial stones buried in Taesil) and Agibi(gravestones buried in Taesil) were created along with taesil. These resources were examined and compared with literature records to find when each taesil seokhams was created. The critical elements to consider for the chronological arrangement were both the cover and container of the boxes and the transition of their style could be classified into four major stages. In detail, the Joseon Dynasty's taesil seokhams initially inherited the style of the Goryeo Dynasty to be formed into rectangular boxes. Through the transition of the mid and late 15th Century, the semi-circular cover with cylindrical container became the popular style in the late 15th Century. In the late 16th Century, the style of the previous period was further developed to add some decorative elements, such as projecting ornaments, but the ornaments were added for functional purposes rather than artistic purposes. However, the style went back to the semi-circular cover with cylindrical container in the early 17th Century. From the mid 17th Century, various styles appeared with ornaments only on the cover, cone-shaped cover with no ornament, or mortar-like container. However, a new style of cone-shaped cover with ornament emerged between the early and mid 18th Century and continued to stay until the mid 18th Century. In the mid 18th Century, the cover remained unchanged, but the container became a keyhole-shaped space with one side forming a "ㄷ" shape. However, in the late 18th Century, the most typical style of the semi-circular cover with cylindrical container reappeared to show that this is the most universal style. Last, in the mid 19th Century, the cover changed from semi-circular to rectangular with flat top. After this, the taesil seokhams began to disappear. In terms of style, it can be classified into four stages. In the early Joseon Dynasty, the taesil seokhams were underdeveloped and inherited the style of the Goryeo Dynasty (Stage I; 1401~mid-15C), but Joseon's unique style began to develop from the late 15th Century (Stage II; 1477~1641). After that, partial ornaments were added for adornment (Stage III; 1660~1754), but the typical style reappeared in the late 18th Century to finally degrade in the late Joseon Dynasty of the mid 19th Century (Stage IV; 1790~1874). This arrangement of style and chronology would greatly help archaeologists anticipate the time and owner of taesil seokhams even if only taesil seokhams are discovered without any records. * Tae(胎) : Placenta and umbilical cord * Taesil(胎室) : A facility(chamber) of burying Tae(胎) in rite when royal descendants are born.
