In this paper, we study the structure of the Daegyupyo (大圭表, Large Gnomon) of the early Joseon dynasty. A Gyupyo (圭表, Gnomon that is Guibiao as pronounced in Chinese) is composed of a Pyo (表, Biao as pronounced in Chinese) making a shadow and a Gyu (圭, Gui as pronounced in Chinese) measuring its length. It is known that the Daegyupyo with the 40-feet height was constructed between the sixteenth to seventeenth year of the King Sejong reign (1444 - 1445) on the basis of the record of Yuanshi (元史, the History of the Yuan Dynasty). By analyzing historical documents such as Joseonwangjosillok (朝鮮王朝實錄, the Annals of the Joseon Dynasty), Yuanshi, and Jegaryeoksangjip (諸家曆象集, a work written by Sunji Lee), we found a possibility that the Ji (池, a pond) on the Gyu was located in the north side of the Pyo. This structure is different from that in previous studies, but is in a good agreement with that of the 40-feet Guibiao remaining in Dengfeng (登封) of China. Regarding to the Hoengyang (橫梁, cross-bar), we suggest that it was set up by double 5-feet supporting arms apart from the north tip of the Pyo in the radial direction. The 3:4:5 ratio in a rectangular triangle was used to place the Heongyang on the top of the Pyo at a distance of 4-feet (3-feet) in the vertical (horizontal) direction. We also discuss the structural problem when the Hoengyang is positioned apart from the top of the Pyo by supporting arms. In conclusion, we think that this study should be useful in restoring the Daegyupyo of the Joseon dynasty.

한국의 전통 천문학은 과거 중국의 영향을 받아 여러 면에서 중국과 비슷하지만 별자리 모양이나 별이름 등에서 중국과 구별되는 특징을 가지고 있다. 이 연구에서는 규장각에 보관중인 조선 초기의 보천가와 중국 수대(隋代, $581{\sim}618$) 왕희명(王希明)이 저술한 보친가를 비교하여 분석하였다. 두 보천가에 그려진 천문도 별자리 모양과 연결선 그리고 본문 설명에 대하여 각각 비교하였다. 두 책을 비교 분석한 결과 별자리 설명의 여러 부분에서 전반적인 차이가 있음을 확인하였다. 첫째 두 서적의 구성에서 서문과 삼원 별자리, 은하수 설명은 확연한 차이를 보여 준다. 둘째, 보천가에 그려진 전반적 별자리 그림은 비슷하지만 별자리의 연결선과 별의 개수가 여러 곳에서 다르게 그려져 있다. 셋째, 조선의 보천가는 중국 왕희명 보천가와 달리 별자리 설명에서 별의 색깔을 표현하고 있다. 이러한 두 나라 보천가의 차이점과 조선 보친가의 고유한 특징을 찾아 논문에 정리하였다. 조선 보천가와 중국 보천가의 여러 차이점은 우리 고유의 천문지식과 체계가 고려시대 이전부터 꾸준히 전해져 왔음을 짐작케 한다.

Cultural heritages represent the histories and intellectual level of a country. The Annals of Joseon Dynasty are regarded as the most valuable resources containing the record of Korean history. In some periods, wax-treated paper was used as the material of the Annals of Joseon Dynasty. Many previous studies have focused on the development of paper used as the material of the Annals of Joseon Dynasty, but the manufacture method of wax-treated volumes and the degradation mechanism of wax have been not fully understood yet. The purposes of the present study are to produce various kinds of wax-treated paper using by different coating methods and to analyse the morphological properties of wax-treated paper. The analysis of SEM demonstrates that beeswax treated paper made by brushing method produces flatter surface and more excellent penetration. Wax layer is produced on the cross section of beeswax treated paper as the increase of coating amount.

Today We have three full series of the annals of Joseon Dynasty. Taebaeksan volume which is one of them shows comparatively good maintenance but Taebaeksan volume also decomposed in patches. The size of cover and inner paper were increased in late Joseon Dynasty, but the weight, thickness and basis weight bears no relation to each other. The oxidation index of paper in annals of pre-periods of King Sunjo shows very high value. After the annals of King Sunjo, the oxidation index of paper is very similar to today's Hanji. L.a.b values of inner paper in the Taebaeksan volume are similar generally. The average length of fiber using image analysis soft ware is 8.08~9.92 mm, that like immediate value of measurement. The air fraction of fiber's range is 1.20~2.12%. It lower than today's Hanji. After considering the factors of the length of fiber, air fraction and FE-SEM, we reached that no difference between raw material of inner paper in the Taebaeksan volume.

The annals of Joseon Dynasty has been known as one of the UNESCO's Memory of the World Heritage. The annals of Joseon Dynasty composed with two kind of books, wax coated book and non coated book. Especially the waxed book have been severely damaged by various reason. For the safety preservation of the annals of Joseon Dynasty waxed book, the thermal ageing mechanism of beeswax coated Hanji paper has been evaluated. The weight loss of waxed Hanji were rapidly increased until 30 days in three temperatures(105, 120 & $150^{\circ}C$) and stabilized after 30 days. The acid value and relative intensity of carbonyl groups in beeswax were increased with strong conditions. This means that the deterioration of beeswax should be progressed with oxidizing reaction. The physical strength and the crystallinity of dewaxed Hanji were decreased with ageing time.

Objective: To understand the domestication and spread of horses in history, genetic information is essential. However, mitogenetic traits of ancient or medieval horses have yet to be comprehensively revealed, especially for East Asia. This study thus set out to reveal the maternal lineage of skeletal horse remains retrieved from a 15th century archaeological site (Gongpyeongdong) at Old Seoul City in South Korea. Methods: We extracted DNA from the femur of Equus caballus (SNU-A001) from Joseon period Gongpyeongdong site. Mitochondrial (mt) DNA (HRS 15128-16116) of E. caballus was amplified by polymerase chain reaction. Cloning and sequencing were conducted for the mtDNA amplicons. The sequencing results were analyzed by NCBI/BLAST and phylogenetic tool of MEGA7 software. Results: By means of mtDNA cytochrome b and D-loop analysis, we found that the 15th century Korean horse belonged to haplogroup Q representing those horses that have historically been raised widely in East Asia. Conclusion: The horse is unique among domesticated animals for the remarkable impact it has on human civilization in terms of transportation and trade. Utilizing the Joseon-period horse remains, we can obtain clues to reveal the genetic traits of Korean horse that existed before the introduction of Western horses.

There are three kinds of books written by different authors in different regions in the 19th century. These books include "BonChoYuHam (本草類函)" (1833), "BonChoBuBangPyeonRam (本草附方便覽)" (1855) and "BonChoBang (本草方)" (1860?). However, these books are very similar in terms of content and format. They were written in the format of large medical books and they contained prescriptions made up with 1-2 kinds of herbals depending on diseases. These three books which could not affect each other appear to have these commons. The reason is that these books were newly edited based on Bubang (附方) in "BenChaoGangMu" depending on diseases and "BenChaoWanFangZhenXien" (1712) written by Cai, lie Xian (蔡烈先) was used as the reference. Woodblock printed book of "BenChaoGangMu" viewed by medical practitioners in Joseon Dynasty in the 19th century mostly had "BonChoManBangChimSun" which could be called '"BenChaoGangMu" Bubang index' as the appendix. All authors of three books tried to make 'reorganization of "BenChaoGangMu"' by using "BonChoManBangChimSun" as the important reference. Work of 'reorganization of "BenChaoGangMu"' focusing on symptoms being made in the 19th century was made a few times in the 20th century. "YangMuSinPyeon" and "SuSeBiGyeol" published in 1928 were outcomes of these works in the 20th century. 'Reorganization of "BenChaoGangMu"' being made in 19th-20th centuries showed great interest for "BenChaoGangMu" in the medical community in the late Joseon Dynasty. In addition, the practical scholarship of Joseon Dynasty gave "BenChaoGangMu" the value as the collection of prescriptions rather than the concept of book for herbal medicine. Prescriptions of reorganized "BenChaoGangMu" have been spread out to many books in the late Joseon Dynasty. Thus, the impact of "BenChaoGangMu" on society in the late Joseon Dynasty seems to be much larger than what has been known so far.

The purpose of this study is to classify and recreate the grooming styles of facial hair sported by noblemen during the Joseon Dynasty. Using existent portraits painted during this period as corroborative materials, this study has identified the traditional grooming styles of facial hair sought by noblemen in this age. This study has utilized 30 facial hair styles found in the portraits of noblemen inherited from the Joseon Dynasty, which take up the majority of the portraits currently remaining in Korea. To recreate grooming styles of facial hair, this study has divided facial hair into three types according to its location: beards, moustaches and whiskers. Based on the analysis of these divided grooming styles, this study has recreated grooming styles of facial hair by using artificial modelling heads, artificial hair, artificial glue, scissors, and a comb. The grooming styles of facial hair recreated by this study are closest to those that noblemen sought and did wear during the Joseon Dynasty. The results of this study are as follows. First, they groomed their moustaches in the 八 shape. Next, they wore their beards in the shape of an inverted triangle. Finally, they also grew and groomed whiskers. Though there are individual differences in the location, length, and volume of facial hair, noblemen in the Joseon Dynasty generally sought to wear their facial hair neat and long. Little research has been done to recreate and present noblemen's grooming styles of facial hair focusing on portraits. Thus, the findings of this study are expected to be utilized as basic materials for the education and research of grooming styles of facial hair according to ages. They can also be used as basic materials for recreating facial hair in historical dramas.
