We have performed analyses using ancient DNA extracted from 25 excavated human bones, estimating around the 1st century B.C. Ancient human bones were obtained from Nukdo Island, which is located off of the Korean peninsula of East Asia. We made concerted efforts to extract ancient DNA of high quality and to obtain reproducible PCR products, as this was a primary consideration for this extensive kind of undertaking. We performed PCR amplifications for several regions of the mitochondrial DNA, and could determine mitochondrial haplogroups for 21 ancient DNA samples. Genetic information from mitochondrial DNA belonged to super-haplogroup M, haplogroup D or its sub-haplogroups (D4 or D4b), which are distinctively found in East Asians, including Koreans or Japanese. The dendrogram and principal component analysis based on haplogroup frequencies revealed that the Nukdo population was close to those of the East Asians and clearly distinguished from populations shown in the other regions. Considering that Nukdo is geologically isolated in the southern part of the Korean peninsula and is a site of commercial importance with neighboring countries, these results may reflect genetic continuity for the habitation and migration of ethnic groups who had lived in a particular area in the past. Therefore, we suggest that phylogenetic analyses of ancient DNA have significant advantages for clarifying the origins and migrations of ethnic groups, or human races.

Woman in Choson era had various kind of accdssories like rings, ear ring, ornamentak hairpins and so on. Among them their favorite was the Norigae, the pendent trinket. With the embroidered ornament at its center, beads and knots were attached to the upper and lower part, and it was hung with a tassel. It was carried on the string of the Chogori. norigae oreginated in waist string of Three Countries era(Sills, Paekje and Koguryo) ; had been changed with the development of fashion, embroidery and the influence of Buddhistic culture. The differences between Embroidered Norigae and Norigae are following. If the ornament at its center is made of such jewels as gold, silver, jade and the like, it is called Norigae. But if the ornament at its center is made of the embroidered Norigae. Such a Embroidered Norigae in which perfume was contained, was as a perfume box or a perfume bag and was carried on the strings of Chogori by Danjak(single work). The Differences between ancient Embroidered Norigae of late Choson era and modern Embroidered Norigae are Following; 1) The type of main body-the embroidered ornament at its center was mainly embroidered with the shape of animals in both of ancient Embroidered Norigae was usually formes like a bat and that of modern Embroidered Norigae like butterfly. 2) plants were adapted as the main design of ancient Embroidered Norigae, but plants and animals as that of modern Embroidered Norigae. 3) The colors of the background and the design are usually red in both ancient and modern Embroidered norigae. 4) The tassels of ancient Embroidered Norigae were mode in the shape of srick and a strawberry. but the tassels of modern Embroidered Norigae were mainly made in the shape of a stick. 5) Nowadays the beauty of external form is considered more important while the symbol of main body was considered more important in Choson era. 6) The role of Thidon in the composition of Embroidered Norigae is declined and a lot of main bodies are used in modern Embroidered Norigae. 7) Modern Korean people are apt to choose Embroidered Norigae depending upon the design of main body and the traditional Korean beauty. 8) Modern people who desire to get new thing, try to make the design of main body various. As their cognition of Korean tradition is of the increase, the restoration of ancient Embroidered Norigae to its original form has been accom

This study is about the costume relics that were excavated from M10 of the 6th site, M13 and M14 of the 8th site among all the Runghai(龍海) ancient tomb sites that were known as the royal family's tombs of Balhae, which were built from the late 8th century to the early 9th century. These costume relics were also introduced in the academic journal of Chinese archaeology(考古) 6 in 2009. The summary of the results that focused on finding features of the costume relics and its meaning were as follows: 1. Male and female statues, both of which were excavated from the Runghai ancient tomb sites, had the shape and composition of the government official's costumes such as the Danryeong(團領), Bokdu, and Gwadae. The female's hairstyle and accessories were quite similar to other costume relics of Balhae. In particular, the male statues wearing the Danryeong and Bokdu were considered as the normal figures of government officials of Balhaeafter the mid 8th century. 2. The female statue wearing the male attire is considered as a maid, and we can confirm that women dressing up like a man was a popular trend in Tang(唐), and this trend was introduced to Balhae. 3. The back flap(垂脚) of Bokdu that the male statue is wearing in M10 of the 6th site, has a shape that has not been found in the ancient relics of both Balhae and Tang. Therefore, it is considered as a unique shape of Bokdu of Balhae. However, it needs to be observed more and discussed in the future. 4. In regards to the Gwadae, the outside of the Gwadae is decorated with jade and has an embossed carving that is gold inside. The Gwadae of the Runghaisites has a unique design and it is distinguished from other ancient relics. 5. The gold trefoil crown and the leather conical hat that were found in M14 of the 8th site can be seen as the basic composition of official's hats in ancient Korea. Also, the motif of the gold trefoil is closely related to Anthemion that is often seen in the relics of the Three Kingdom period. Thus, we can assume according to this important finding that the style of ancient Korea official's hats came from either the king or a royal family of Balhae after the mid 8th century.

본고는 원말명초(元末明初) 문학의 전개과정을 검토하면서 명대(明代) 초기 관각문학의 기틀을 다졌던 송렴(宋濂) 문학의 위치를 점검해 보았다. 그는 명대 문학사에서 도학자적 문학관을 견지했던 것으로 단순 요약되고 있지만, 그 과정은 그리 간단하지 않다. 본고는 문학론과 관련된 송렴의 글을 연대기적으로 분석함을 통해 그가 청 장년기까지도 진한고문(秦漢古文) 등의 고문사(古文辭)에 빠져 오랫동안 헤어 나오지 못했음을 밝힐 수 있었다. 송렴은 삼십 세에 스승 황진(黃?)과의 만남을 계기로 육경에 침잠하며 도학적 문예관을 가지게 되었지만 고문사의 유혹을 완전히 떨쳐버리지는 못했다. 오십 이후 주원장(朱元璋)을 도와 명 건국의 주역으로 참여하게 되면서 비로소 자신의 경세적 문학관을 실천적으로 확립하였고, 이후 자신의 도학적-경세적 문학관을 이론적으로 정립할 수 있었다. 그리고 이 과정은 또한 청 장년기 그 자신의 문학 수련의 주요한 대상이자 명초의 가장 중요한 문학적 전범이기도 하였던, "사기" 등의 진한고문을 부정하는 과정이기도 하였다. 요약하면, 원말명초의 격동의 시기에 송렴은 개인적, 시대적으로 문학관의 변화를 겪으며, 그 생애 말년에 육경 및 송대의 도학자와 한유(韓愈) 구양수(歐陽脩) 등의 당송고문을 성인(聖人)의 문(文)으로 통하는 치세의 문학으로 재정립함으로써 명대 문학의 이념적 좌표와 새로운 문학적 전범을 제시하고 있었던 것이다.

It has been considered that 'exhausted eclipses' (日食旣) were total eclipses. However, modern precise calculations show that a significant fraction of such records are not realized to be total. Thus we doubt that the two concepts are equivalent. Here we investigate the meaning of 'exhausted eclipses' in the east-Asian history. We first find that eclipses of magnitude greater than 0.8 were regarded as 'exhausted eclipses' by a Korean astronomer of the 18th-century Choson dynasty. His notion was based upon the definition of 'exhausted eclipses' in the ephemerides of pre-modern Chinese dynasties. According to those ephemerides, the 'exhausted eclipses', whose magnitude is greater than 0.8, have the first contact at the western part of the solar disk and the fourth contact at the eastern part of the solar disk. A simple geometrical calculation shows that such cases really occur when the magnitude of eclipse is greater than 0.7. We pointed out that such an ancient definition might not be impractical for ancient astronomers, because the uncertainty of eclipse magnitude estimated by ancient Chinese ephemerides was 10% and the human sight has a spatial resolution of 1.2 arcmin, which is approximately one twentieth of the Sun's angular diameter.

Seonya theory(宣夜說) was one of the most important metagalaxy model in the ancient times. Unlike the other important metagalaxy model, it had the concept that the sky is not in the solid state but is just the infinite space which is full of gi(氣). But Seonya theory, though it had partially the superb academic thought, it had gradually become the forgotten thing among scholars in the ancient times. Since then, once forgotten Seonya theory was reconstructed again in Song(宋) dynasty, and Jangjae(張載) did the main role at that time. In the historical sequence like this, we need to take notice of one thing that "Hwangjenaegyeong(黃帝內經)" had worked on Jangjae as the origin of his sunya theory. So we also need to take notice of one thing that "Hwangjenaegyeong" is just a rare document that comprises the academic thought of Seonya theory which had once been forgotten in ancient times. Based on the historical situation like this, this study is focused on the idea that the discuss on the Jangjae's Seonya theory would be a good way to think of the cosmic theory of "Hwangjenaegyeong" and the theoretical thought derived from them. So this study will first look into the academic characteristics of Seonya theory of ancient times and of "Hwangjenaegyeong" and through the study on the academic characteristics of Jangjae(張載)'s Seonya theory, will also think of the significance of the thought of Jangjae's Seonya theory that would be some help to the research on "Hwangjenaegyeong".
