This study aims to develop a restoration model of an armillary sphere of Tongcheon-ui (Pan-celestial Armillary Sphere) by referring to the records of Damheonseo (Hong Dae-Yong Anthology) and the artifact of an armillary sphere in the Korean Christian Museum of Soongsil University. Between 1760 and 1762, Hong, Dae-Yong (1731-1783) built Tongcheon-ui, with Na, Kyung-Jeok (1690-1762) designing the basic structure and Ann, Cheo-In (1710-1787) completing the assembly. The model in this study is a spherical body with a diameter of 510 mm. Tongcheon-ui operates the armillary sphere by transmitting the rotational power from the lantern clock. The armillary sphere is constructed in the fashion of a two-layer sphere: the outer one is Yukhab-ui that is fixed; and the inner one, Samsin-ui, is rotated around the polar axis. In the equatorial ring possessed by Samsin-ui, an ecliptic ring and a lunar-path ring are successively fixed and are tilted by 23.5° and 28.5° over the equatorial ring, respectively. A solar miniature attached to a 365-toothed inner gear on the ecliptic ring reproduces the annual motion of the Sun. A lunar miniature installed on a 114-toothed inner gear of the lunar-path ring can also replay the moon's orbital motion and phase change. By the set of 'a ratchet gear, a shaft and a spur gear' installed in the solstice-colure double-ring, the inner gears in the ecliptic ring and lunar-path ring can be rotated in the opposite direction to the rotation of Samsin-ui and then the solar and lunar miniatures can simulate their revolution over the period of a year and a month, respectively. In order to indicate the change of the moon phases, 27 pins were arranged in a uniform circle around the lunar-path ring, and the 29-toothed wheel is fixed under the solar miniature. At the center of the armillary sphere, an earth plate representing a world map is fixed horizontally. Tongcheon-ui is the armillary sphere clock developed by Confucian scholars in the late Joseon Dynasty, and the technical level at which astronomical clocks could be produced at the time is of a high standard.

Lacquer is one of the most widely used natural resin in East Asia since Neolithic Age. As a major ingredient of lacquerware, lacquer is waterproof, insect-proof and rot-proof to be durable and anti-abrasion, generally utilized for mainly painting purpose. According to lacquerware excavated from several sites of Japan and China, lacquerware seems to appear in Neolithic Age. On the other hand in case of excavation research in Korea, lacquerwares are found after the Bronze Age. The initial purpose of lacquer is estimated to be adhesive, regarding the literatures mentioning bitumen(Yeoksceong ), animal glue(Kyeo) and egg alumen(Nanbaek). Especially piece of jar coffin unearthed in Pyeongtaek Daechu-ri site had trace of restoration by lacquer and hemp as an evidence of lacquer for adhesion in Pre-Three Kingdoms period. Since then a trend to restore the broken ceramics with lacquer and decorate with golden foil lasted especially in Joseon Dynasty. In the field of gold plated lacquer method, mother-of-pearl inlaying technique for lacquerware and restoration of buildings, lacquer is still used as adhesive. Due to matter of reversibility lacquer is being avoided for conservation and restoration of cultural heritage. Lacquer as a traditional material for adhesive since ancient times, however, has advantage in adhesion strength and durability. Because synthetic resin adhesive has problem of emission of volatile organic compounds and aging over time, lacquer receives attention recently. On the contrary, by combination adhesive from mixing lacquer and animal glue, already proved the possibility of applicability and chemical modification. A research to utilize lacquer as modern paint or functional material is also conducted continuously also in China and Japan. To put traditional material into practical use and modernize, chemical research from the molecular level of the lacquer is necessary in the near future.

For the preservation and efficient content sharing of 5 volumes (2,866 pages) of Yu Kil-Chun's book published in 1971, which provides an important collection of data for the study of modern Korean history during the late 19th century (enlightenment period of Joseon dynasty). The books were purchased and its preservation status investigated and documented electronically by scanning for permanent preservation of content and to determine the condition of preservation at the time of documentation. The degree of deterioration and damage, such as discoloration, hardening, breakage, and damage in these 50 years old modern printed books was quantified through image analysis and made attempts to visualize the damaged areas. It was observed that the degree of deterioration and damage depended on the material and the surface condition of the paper used, the degree of exposure to light, and the storage environment. The comparison of the preservation status at the time of the photographing (or scanning) and judgment as to whether or not the image under investigation was artificially modified was accomplished by comparing the electronically documented images of Seoyugyeonmun (西遊見聞) in Volume 1 of Yu Kil-Chun's works with images provided on other websites. Practical problems encountered while considering the effective preservation of electronically documented data and publicly sharing it, in the course of this study, with other academic researchers around the world were also summarized.

This paper is to clarify the literary value of sino-korean poems interposed in Changseongamuirok. As the author of Changseongamuirok is thought to be a person with considerable knowledge of sino-korean literature, the sino-korean poems interposed in Changseongamuirok can be the clue to examine his literary ability. Furthermore, evaluation on the sino-korean poems interposed in Changseongamuirok can have the verification of Changseongamuirok's literary value and of the author's ability to create novels and to compose literary pieces be possible, and is thought to help determining who wrote Changseongamuirok. The sino-korean poems interposed in Changseongamuirok is not necessary parts for composition or development of the entire piece but additional parts for explaining and verifying characters and situations. Functions and roles of the interposed sino-korean poems are indeed very limited, but it is thought that the reason the author interposed such sino-korean poems into the piece is that those poems perform functions more than superficial limited ones. When the composition of Changseongamuirok and the literary achievement of its interposed sino-korean poems are examined, it can be thought that the author of Changseongamuirok achieved the level of professional novel writer. From the point of view, it can be said that Changseongamuirok was written in the time closer to the $19^{th}$ century than to the $17^{th}$ century and that the author also had literary and narrative creativity with considerable sino-korean literary ability. Such an author adopted sino-korean poems since he thought those interposed sino-korean poems took important roles for strengthening novelistic value and literary excitement. Further and deeper interests in and researches on sino-korean poems interposed into novels of Joseon dynasty period are expected.

Park Se-dang who has the pen name of Seogye is a man in the 17th century. Then, Joseon Dynasty is try to restore the state which became impoverished by two wars. When Sung Confucianism of Chu-tz was dogmatized, Seogye analyzed independently the scriptures and was regarded as a traitor against Sung Confucianism. Therefore, this paper discussed the understanding of Seogye's works and its social reflection through the research data about Seogye. Although Seogye has blue blood in his veins, he belonged to a non-mainstream group in the faction of Seo-in and had a liberal inclination. That he has shuned in the school of Sung Confucianism owed to Sabyeunrok of his work, and its main reason is his criticism against Song Si-yeul. He argued the two principles different from Chu-tz's three principles. Also, he not accepted the Chu-tz's theory and was similar to the Wang Yangming school in the issue of gaining knowledge by the study of things Now to conclude, Seogye outstretched the liberal inclination in Sung Confucianism apart from the interpretation of scriptures. He was not indulged in Sung Confucianism of Chu-tz that was gradually ossifying at that time and took his own line. And he devoted himself to the study of practical learning and the education for younger scholars, and had acted as mediator between the Sung Confucianism of Chu-tz and the Practical Science that was in full bloom in the period of King Young-jo and King Jeong-jo.

This thesis is about Chungyongkugyongyonui(中庸九經衍義) by HoiJae Lee Eon Jeok (1491~1553). As many know, he was one of the philosophers representing the 16th century who played a great role in making the Zhūzǐ's Neo-Confucianism settle down in Joseon society through the dispute on TaeGeuk (太極) against Cho Han Bo (?~?). He was also the scholar who firmly established the theoretical system of the Idea for Proper Governance (至治主義). The Supplementary Explanation to the Chapters and Phrases of the Great Studies (大學章句補遺) and the Transcript of Nine Annotations on the Middle Way (中庸九經衍義) were written to argue his thoughts of the Idea for Proper Governance shown in the Great Studies (大學) and the Middle Way (中庸). He said that the Great Studies was more specific in the clauses for the justice of training oneself while the Middle Way more detail in the clauses for the justice of governor. That is, he thought that those books were in the relation of the in-and-outside, so that he argued that kings should take both justices of such for governance. Especially the Transcript of Nine Annotations on the Middle Way was written by following the way of the Annotation Transcript of the Great Studies (大學衍義) by Jin Deok Su (眞德秀), a scholar of Song Dynasty and the Supplementary Explanation to the Annotation Transcript of the Great Studies (大學衍義補) in order to make the King MyeongJong of that period realize the Proper Governance of the Two Great Emperors and Three Great Kings of Ancient China, which greatly influenced the Ten Figures of the Studies for the Great Man (聖學十圖) by ToiGye Lee Hwang and the Abstract of the Studies for the Great Man (聖學輯要) by YulGok Lee Yi.

The history of modern libraries in Korea is less than 150 years. Nevertheless, there are various issues about when the word library appeared, how it was transformed, and the name and overall appearance of the library opened by the Busanpo branch of the Nihon Kodo-kai during the enlightenment period. Therefore, this study analyzed and argued many issues. As a result, it was found that the word library appeared in poetry collections, tombstones, and diaries from the early Joseon dynasty. Although it was widely held that the library was first introduced by Yu Gil-jun's 「Seoyugyeonmun, 1895」, it appeared in Lee Hun-young's 「Iisajipryak」 and was also introduced in 「Hanseongsunbo, 1884」. And the first name given to the facility was Kodo library, which was opened by the Busanpo branch on October 10, 1901. Book club, reading club (library), Busan(Busan district) library, Kodo bookstore, Kodo-kai library, etc. which are described in many documents are all errors. The location of the library was a temporary house on a leased site in Seosanhajeong of Yongdusan mountain. And it is presumed that it has secured about one room and 1,000 Japanese and Western books, and provided fee-based services to Japanese residents. Although the Kodo library is not the first public library established by a Korean, it is undeniable that it was the first public library to exist in Korea. Therefore, when defining the character of the Kodo library, it is necessary to have a coolness and discernment beyond national emotions, historical conflicts, and ideological frames.

The Tomb of Jang Mui was discovered and investigated during the Japanese colonial era. It has provided key archaeological material for identifying the Daebang Commandery mentioned in historical records as Sariwon in Hwanghae-do Province when some bricks used in the construction of the tomb were found to be stamped with the official title "Prefect of Daebang Commandery." The discovery of the Tomb of Jang Mui served to confirm that the brick chamber tombs found along the Daedonggang River in 1909 were related to the Nangnang Commandery. It can be viewed as a major archaeological breakthrough that settled a debate over the locations of the Daesu River and Daebang Commandery that had been ongoing since the early Joseon Dynasty. Despite its significance for archeology and ancient Korean history, the circumstances of the discovery and investigations of the Tomb of Jang Mui have not been thoroughly examined. Inscribed bricks and roof tiles unearthed during the excavation conducted by Sekino Tadashi in 1912 are currently housed at The University Museum of The University of Tokyo. A number of other bricks excavated from the Tomb of Jang Mui are in the collection of the National Museum of Korea. Main agents of the investigations into these materials have not all been identified. Only some records on the materials collected during the investigations by Nomori Gen and others specify the main investigators. Inscribed bricks from other related tombs are also found in the Tokyo National Museum and at several universities in Japan. It is hoped that a comprehensive report incorporating all these materials can be written. Based on a reinterpretation of its structure conducted by Jung In-seung in 2010, the Tomb of Jang Mui has been dated to 348. This means it was not built during the Daebang Commandery period. The most compelling archaeological evidence regarding the location of the Daebang Commandery and its local capital has been undermined. It is hoped that active discussions will be held on the issue of the Daebang Commandery and its local capital.

Bi-Seok is a treasure trove of funeral rites and an important cultural asset that can shed light on the historical and social history of calligraphy, but research of the topic is still insignificant. In particular, research on the production method of Bi-Seok remains an unproven field. The production of Bi-Seok can be roughly divided into ma-jeong (refining stone), sculpture, and the Buk-chil (process of engraving letters) process. This article reveals some facts: First, performing ma-jeong to the Sang-Seok, Honyu-Seok, Bi-seok, which are known to be God's things. This process is needed because of the change in the perception of the Honyu-Seok due to the settlement and propagation of Confucian ceremonial rituals in the times of hardship in 1592 and 1636. As the crafting process of ma-jeong did not remain concrete, it was only possible to examine the manufacturing process of Bi-Seok through its materials and tools. Second, the rapid proliferation of Oh-Seok and Sa-jeo-chwi-yong (purchase of things made by private citizens) in the Yeongjo era has great importance in social and cultural history. When the Gang-Hwa-Seok of the commodity were exhausted, the Oh-Seok that was used by Sadebu (upper civil class) were used in the tomb of Jangneung, which made Oh-Seok popular among people. In particular, the use of Oh-Seok and the Ma-Jeong process could minimize chemical and physical damage. Third, the writing method of the Bi-seok is Buk-chil. After Buk-Chil of Song Si-Yeol was used on King Hyojong's tomb, the Buk-Chil process ( printing the letters on the back of the stone and rubbing them to make letters) became the most popular method in Korea and among other East Asian countries, and the fact that it was institutionalized to this scale was quite impressive. Buk-Chil became more sophisticated by using red ink rather than black ink due to the black color that results from Oh-Seok. Fourth, the writing method changes in the late Joseon Dynasty. Until the time of Yeongjo's regime, when inscribing, the depth of the angle was based on the thickness of the stroke, thus representing the shade. This technique, of course, did not occur at every Pyo-Seok or Shindobi, but was maintained by outstanding artisans belonging to government agencies. Therefore, in order to manufacture Bi-Seok, Suk-seok, YeonJeong, Ma-jeong, Jeong-Gan, ChodoSeoIp, Jung-Cho, Ip-gak, Gyo-Jeong, and Jang-Hwang, a process was needed to make one final product. Although all of these methods serve the same purpose of paying respects and propagandizing the great work of deceased persons, through this analysis, it was possible to see the whole process of Pyo-Seok based upon the division of techniques and the collaboration of the craftsmen.

This study aims to find out the characteristics of the vegetation landscape characteristics and system which led the formation of the urban image in Jeonju in the late Joseon period connected with urban spatial structure, using designated as treasure No. 1586 which was made in the middle of 18C. The vegetation landscape characteristics of Jeonju in the late Joseon Dynasty derived from the analysis of are summarized as follows. Firstly, the vegetation landscape system in Jeonju is composed of the natural vegetation around mountain area of Jeonju-Buseong, the independent vegetation or cluster planting forests linked with the main facilities, the Bibo-Forests connected with topographical characteristics of Jeonju, and the vegetation combined with a private garden. Secondly, planting landscape was specialized using flag species and local species. Thirdly, the garden-type plantation centered on the back yard or front of main facilities, with the background of natural vegetation landscape combined with the mountain area and the vegetation combined with a private garden, dominates vegetation landscape of Jeonju Buseong as objects. Fourthly, in order to overcome the defects of topographical characteristics, the Bibo-Forests were emphasized as an important planting landscape element in addition to the vegetation landscape elements connected with main facilities. Fifth, ecological vegetation landscape technique was taken considering the topographical characteristics. The characteristics of vegetation landscape of Jeonju Buseong, which is derived from , have an important meaning to restore and reproduce Jeonju's historical features. Especially, the vegetation communities of the non-booming concept combined with the geographical features, the ecological landscape harmonizing with the topography, the round house type landscape mixed with the private house, and the specialization of vegetation landscape using local species are important factors in securing the city image based on the historical characteristics and creating a city brand that utilizes vegetation landscape.
