In Korean historical documents, there are a great number of the records for various astronomical events. In particular, historical documents of the Joseon dynasty also have the records containing observational data by an astronomical instrument. However, a quantitative analysis for the accuracy of observational values have never been studied, although there are some studies on the truth of the records themselves. Hence, we investigated observation errors during the period of the Joseon dynasty from the records of Joseon-Wang-Jo-Sil-Lok (the Annals of the Joseon Dynasty) and Seung-Jeong-Won-Il-Gi (Daily Records of the Royal Secretariat). We used the records of the Mars, supernova 1604, and Halley's Comet, and found that observational values before the Hideyoshi invasions in 1592 are relatively more accurate than those after then. However, because the number of cases used in this study is small, we think that more studies are needed to confirm our results. Nonetheless, we reckon our work will be of service to understand astronomical records of the Joseon dynasty.

Studies were conducted on manufacturing techniques by applying microscopy and conservation treatments on the annals of Joseon dynasty storage box at the National Museum of Korea. The results revealed that lime tree wood(Tilla spp.) was used to make the annals of Joseon dynasty storage box. Lacquering techniques were used to coat the box with a layer of lacquer and bone ash and then cover it with traditional Korean paper. After being covered with traditional Korean paper, more layers were applied in the following sequence: mud ashes, black lacquer, pure lacquer, and black lacquer. Before conservation treatments, some components and lacquer layers were missing in addition wood joint were loose. Therefore, conservation and restoration should be conducted based on the identified wood and by observing the shape of the remaining components.

We tried to establish the history of outbreaks and control methods of 'hwangchung' in Joseon Dynasty, uncovering the biological reality of the 'hwangchung' (called hwang or bihwang) analyzed through the Database program on 'the Annals of the Joseon Dynasty' and 'the Emollment of Haegoeje', two of the finest examples of classical historical records. The total number of articles on the outbreak of the hwangchung is 261 in the Annals of the Joseon Dynasty and 65 in the Emollment of Haegoeje. There were four peaks by hwangchung throughout the Joseon Era. Among them, the periods of King Taejo to King Sejong had the highest incidence. By comparing the number of records of the hwangchung from the Annals of the Joseon Dynasty with that in the Emollment of Haegoeje during the same period, results show the former was less than the latter, 35 vs 65. However, both records were relatively inconsistent with each other. Insect pests in forests as well as in agriculture were included in the biological identities of the hwangchung in the Joseon Dynasty periods, which is in accordance with those of Saigo's. The taxonomic identity could be confirmed in only 25 cases (9.5%) among the articles on hwangchung. It largely coincided with Paik's opinion: II in armyworm, nine in moth larva, one in rice stem borer, two in migratory locust, one in planthopper and one in rice-plant weevil. Therefore, it is not reasonable to regard hwangchung as a migratory locust or grasshopper only. The number of reports on the occurrence of hwangchung in the Annals of the Joseon Dynasty was 173 (66% of the total) and 47% of them were just simple reports, which means the report itself on the appearance of hwangchung was very significant. The reports on controlling insect pests were of low frequency, in 20% (34 cases) of the total reports, capturing insect pests or holding traditional ceremony called 'Poje'. Among them, only one case related to the treatment of seeds to prevent the damage by hwangchung was published in the King Sejong period. There were 37 discussions about changes and management of government policies due to disasters by hwangchung. They were mostly about relief or tax cut to the people who suffered damage and about cancellation of recruiting people to military training, constructing castles, and so on. It seems that not only the people but also the king was influenced by the hwangchung. In the case of King Seongjong, he referred to the stress of the prevention measure of locusts in 10 articles. The damage also had an effect on abdication in the reign of King Jeongjong.

The purpose of this research was to identify causes of damage of wax-treated volume of "The Annals of the Joseon Dynasty". As one of the efficient restoration methods, analyses of damaged state of reproduced wax-treated paper through tests of degradation of wax-treated paper under an artificial setting were performed, and in particular, differences between lightness and acidity were observed. On the whole, it was confirmed that yellow wax-treated papers were more stable than white wax-treated papers against artificial aging treatment, which is thought to be because the white wax-treated paper was more affected by a variety of substances interacting with paper than yellow wax-treated paper under artificially aged conditions, which were added in the course of refinement and processing operation such as decolorization and deodorization.

Until now, the studies researching the Taoism theories of Joseon Dynasty have mainly dealt around the latter half of Joseon Dynasty. The reason for that was because the 5 cribs of a book Lao Tzu and the 2 crib of a book Changzi were produced after the Imjin-Year Korean-Japanese War(壬辰倭亂,Imjin Waeran). Therefore this thesis extracted the mentions about Taoism from about 200-year history records from Jeong Do-Jeon's Theory, which was the theoretical foundation for early days of Joseon's foundation and the history book King Taejong's Annals(太宗實錄) contained in The Annals of Joseon Dynasty(朝鮮王朝實 錄) and analyzed the extracted historic data as the first work contemplating how the Taoism theories were developed during the first half of Joseon Dynasty. From the analysis, this study drew out the findings as follows. Jeong Do-Jeon and Gwon Geun sharply criticized the Taoism for that it pursued for the techniques of longevity for oneself without moral. They tried to establish the identity of neo-Confucianism on the foundation criticizing the Taoism and the Buddhism. Since then, the Taoism was transformed through the 3 stages in The Annals of Joseon Dynasty. The first stage was the stage transformed 'Lao Tzu' as the witchcraft master of long-live, the technique of the taoist hermit and the super god in Taoism, and regarded the Taoism as heresy and excluded the Taoism. Second stage was the stage trying to see the book Lao Tzu as the core of Taoism theory separately from the 'Hermit Witchcraft' and the 'Taoist gods' the target of fortune-pursue religion beyond from the primary discussion of exclusion. Third stage was revealed as the respects on the art of politics and the art of living described in the book Lao Tzu. That is, the Taoism theories in the first half of Joseon Dynasty was developed with various spectrums from the early days of Joseon's foundation to 15~16 centuries beyond Joseon's strong suppression against the Taoism and the Buddhism in early days. That is the point that the Taoism in the first half of Joseon Dynasty can't be simply interpreted in the neo-Confucianism. During the firs half of Joseon Dynasty, the warm attitude toward the Taoism was created differently from the attitude against suppressing it as a cult, which had been created in the early days of Josen's foundation, and there appeared the changes accepting the art of living and the art of politics theoretically integrating with the Confucianism theories. That is, the book 'Lao Tus' became accepted as the Confucian country's arts of living and politics from a cult book pursuing for immoral log and immortal life. Such acception is revealed as the appearance actively interpreting the books about Laoism in the latter half o Joseon Dynasty.

Tiny leaf fragments were found in the Annals of the Joseon Dynasty, which were compiled about 500 years ago. The records describing the detailed process of compiling the Annals indicate that silk bags packed with the powders of 'Cheongung' and 'Changpo', which have been used as traditional herbal medicines in the northeast Asian countries such as China and Japan as well as Korea, were put in the wooden storage boxes together with the volumes of the Annals. However, there is no record that parts of plants were used in the process of compiling the Annals. The botanical origin of leaf fragments was identified as Ligusticum sinense 'Chuanxiong' by the analysis of trnK of chloroplast DNA as well as the examination of leaf surface with SEM. The comparative analysis of trnK sequences showed that the chloroplast DNA haplotype of 'Tocheongung', a triploid species cultivated in Korea, was identical with Cnidium officinale, but different from L. sinense 'Chuanxiong'. The molecular results provide a new suggestion on the botanical origin of crude drugs used as 'Cheongung', which has been disputed in Korea.

To explore the paper materials for restoration of the Annals of the Joseon Dyansty, durability of the three type of the traditional Korean Papers were estimated in this study, through moist heat artificial aging test. Three types(D, F, and G) which showed the best preservation performance in dry heat and UV treatment in the previous study were selected and artificial accelerated aging treatment with moist-heat process was conducted; the viscosity change rate was D>G>F; folding endurance G>D>F; $L^*$ value F>D>G; $a^*$ and $b^*$ change rate D>G>F; brightness decrease rate D>G>F, suggesting paper F showed the least change rate in physical/optical properties. Also the CLSM image observation showed fair coherence among fibers and confirmed paper mulberry. And in FDI extraction from each sample, paper F showed the highest value. Overall, paper F (traditional glossy paper) showed the highest stability against thermal treatment. It confirms that paper F is suitable as restoration paper for tributary remains including the annals of the Joseon Dynasty for its steady strength/viscosity decrease rate and color change rate.

Uigwe is official reports of the Joseon dynasty. They published from early Joseon but remain from 17C. We can search many hidden informations in them. Ga-Jungjagak (temporary T-shaped house) is one of them. It is unique architecture of the Joseon dynasty but it doesn't exist now at all. We can see many drawings describing Ga-Jungjagak (temporary T-shaped house) located next to Jungjagak in Uigwe. Jungjagak (T-shaped house) was built in royal tombs for sacrifice. Ga-Jungjagak was built in royal tombs for sacrifice as Jungjagak but existed temporarily. In this study, I want to find the process of norms Ga-Jungjagak in old records, official reports and annals of the Joseon Dynasty. Results are as follows: Ga-Jungjagak is the sacrifice space for queens in royal tombs. It is need to avoid sacrifice of delight and sorrow at the same time. They sacrifice to represent sorrow after the death of kings and queens for three years. After three year, they sacrifice to represent delight for kings and queens became ancestral gods. Ga-Jungjagak was destroyed three years later to combined sacrifices. The shape of Ga-Jungjagak is similar to Jungjagak in the same tomb. But dimensions of Ga-Jungjagak are equal or smaller than Jungjagak and decorations are abstemious.

Astronomical data making such as forming a calendar, period of day, determining the time of rising/setting of the sun and the onset of twilight are essential in our daily lives. Knowing the calendar day of the past is particularly crucial for studying the history of a clan or a nation. To verify previous studies in the calendar day of the Joseon dynasty (1392 - 1910), we investigate the sexagenary cycle of the new moon day (i.e., the first day in a lunar month) by using sources such as results of the calculations using the Datong calendar (a Chinese Calendar of the Ming Dynasty) and the data of Baekjungryeok (a Perpetual Calendar; literally, a one hundred-year almanac). Compared with the study of Ahn et al., we find that as many as 17 sexagenary cycles show discrepancies. In the cases of nine discrepancies, we find that the sexagenary cycles of this study are identical to those of the almanacs at that time. In addition, we study five sexagenary cycles by using the historical accounts of Joseon Wangjo Sillok (Annals of the Joseon Dynasty), Seungjeongwon Ilgi (Daily Reports of Royal Secretariat), Chungung Ilgi (Logs of Crown Prince), and so forth. For the remaining discrepancies, we present historical literature supporting the results of this study. This study will greatly contribute to the identification of the lunisolar calendar days during the Joseon dynasty as the dates of the modern (i.e., Gregorian) calendar.

There are records and claims that tung oil was applied to Korean traditional buildings and furniture as finishing paint. Records of the use of tung oil(桐油) exist in the Annals of the Joseon Dynasty(朝鮮王朝實錄) and The Royal Protocols of the Joseon Dynasty(朝鮮王朝儀軌). However, there is also a claim that tung oil was not produced in Korea on its own, and that tung oil was not applied to important buildings such as palaces. Silhak scholar(實學者) Seo Yu-gu says that in Korea, people do not know how to grow tung trees, and boiled perilla oil is called tung oil. If tung oil was used in the Joseon Dynasty, it would be necessary to use tung oil for waterproof coating to preserve current architectural heritage, otherwise, tung oil coating would not be desirable. Analyzing the Yeonggeon Uigwe(營建儀軌) among the Joseon Dynasty's Uigwes shows that tung oil is neither mentioned nor used. In addition, as a result of analyzing the Uigwes mentioned in tung oil, it was found that perilla oil or Myeongyu(明油), not tung oil, was recorded in the actual material used. Therefore, the records of the use of tung oil during the Joseon Dynasty can be seen as records using Myeongyu(明油) or Beopryeon perilla oil(法煉荏油).
