Hull forms of ancient ships in Korea and China have been changed according to their voyages and routes. Therefore it is necessary for shipbuilding engineers to reestablish the ancient shipbuilding history, and to presume, restore and revive the lost cultural inheritances. We, however, do not have many historical documents or credible materials that can our ancestors' great shipbuilding techniques : at the same time we do not have paid much attention to the research on such documents and materials. This paper aims not only to study and compare shifting process of ancient ship's hull forms in Korea and China by making use of verifiable materials obtained in the process of excavating and restoring Shinan ancient ship. The results of comparing structural characteristics and hull forms of ancient ships in Korea and China and as follwing : (1) Korean ancient ships have transverse beam instead of frame . Judged from the bottomform, Korean ancient ships are grooved clinker type ships of flat bottom type, in which bottom planking is fixed by wooden bar. (2) Chinese ancient ships have transverse bulkhead structure instead of frame, Judged from the bottom form , Chinese ancient ships are rabetted clinker type ships of V-bottom type with a bar keel. The form , the position, and the size of a sail are closely related with the wind force. It is not only quite difficult to presume forms and sizes of ancient ships' sails precisely, but also impossible to come to an accurate conclusion wihtout much experience. Current 10-year-statistics of the wind force are used to obtain presumed routes of ancient ships in Korea and China. Conclusions obtained from the hull form , sail form and size , and mast height of Shinan ancient ship will provide credible data for sea trade routes and transformation capability, and wil be used for effective materials on the study of the shifting process of ancient ships in Korea and China.

Regarding the ancient Sino-Kroea sea communication as the main theme, the propagation of the China-culture in Koran Peninsula and he influence of Chinese ancient shipbuilding technique for Korea are described in the paper. Frequent sea trade resulted in the flourishing of Chinese and Korean harbours on both side of Yellow Sea. Sino-Koran sea communication is of long-standing. Korean Peninsula (KP) is just as the large arm extended to the great sea from the North-east China. It is the Chinese mainland plate-lump's extended part in the Yellow Sea. In the ancient time, the land communication between China and Korea was often not unimpeded, the contact between China and KP, such as the South-Korea, depended on the sea communication mainly, Although the friendly relationship between China and Korea rose one after another in the various historical period, but considering from the great background of people's historical development, just as the modern people benefited fro the Europe-American culture, the people of ancient time also benefited from the China-culture. All China, KP and Japan obtained the development by propagating the ancient China-culture. The seagoing ships which carried out the Sino-Korea sea communication and trade, as the friendly envoys, finished the mission linked u and developed the Sino-Korea culture contact.

Ancient Korean and China litteratures show us that it has been long since people from humbler classes to king most commonly used bast fabrics as materials of their cloth. According to the record of these ancient litteratures, highly developed fine bast fabrics and those woven in figures were used as tribute between ancient Korea and China. In this study we will make a brief research of the history of bast fabric culture from ancient times to the Korea Dynasty in which the bast fabric culture flourished and reached the summit of prosperity. After having compared the bast fabric culture of ancient Korea with that of ancient China in which the bast fabric culture developed very much and bast fabrics were used more commonly as materials of cloth than any other fabrics, we could come to conclusions as follows. 1. Names were given to bast fabrics according to the kinds of bast fibers, the degree of fineness and the containing of figures: Ma-po, Jeo, Jeo-po, Bag-jeo-po, Moon-jeo-po, Po and Se-po. The number of 'Seung' which indicated the degree of fineness was attached to the top of each name to show how fine they are. 2. While the bast fabric of 30 Seung is known to be the most fine one of the ancient China, in ancient Korea fine bast fabric of higher than 30 Seung was woven. This fact proves that the technique of weaving bast fabrics of the ancient Korea was more highly developed than that of ancient China. 3. In ancient China the highest Seung number of the ordinary clothes which were put on after putting off livery of grief was regulated to be 15. But in ancient Korea, Sil-la, it was regulated to be 28. Judging from this fact, we may say that the consumption level of the ancient Korean people in cloth was higher than that of the ancient China people. 4. The reason why in ancient Korea the technique of weaving bast fabrics was so highly developed is suppoed to be that the ancient Korean people preferred elegant, refine and simple taste in cloth. 5. The excellent bast fabric culture of the ancient Korea flowed into ancient Japan. It proves that Korea played an important part in the history of textile development of the world.

The rising of east-north economic bloc is notable in world economy due to the rapidly growth of china economy. The China's economic standing is gradually higher and higher because the joining of the WTO at 2001, development of the exterior open-door policy and the expansion of the trade between chain and several nations. Since Korea and China normalized diplomatic ties in 1992, the two have made remarkable progress in bilateral relations in the fields of economy and diplomacy in particular. The amount of Korea's trade with China has increased by over 20% a year on the average because of the development of the economic cooperation of Korea and China. That is to say, China was sixth trade partner by the end of 1993, based on the amount of trade. But China became third partner at 1993, second partner at 2003 and first partner at the first half of 2004, based on the amount of trade. Korea can not trade with China from the Korea's port opening period to Cold War period after second world war. But historically, the two countries have shared a active and long history of trade relations from the ancient times up to now. This is because two countries get near geographically and two countries have a implication of history and culture. Not only had Korea trade with China at prehistoric age, but also at BC 7. We knew that Korea had traded with China very actively at ancient times through the Paekje(Korea's ancient country) people's village at Santung province and Changbogo's trade works. Korea-china trade relation has played an important role for the development of world economy. Therefor, based on reviewing the korea-china trade, I study the historical meaning of the trade at the region of east-north asia.

This study investigates the crystallinity distribution of ancient silk. Owing to the inherent multi-hierarchical structure of silk protein and the complicated structural changes that occur due to various burial environments, it is challenging but worthwhile to study ancient silk ageing behavior, which is based on the fact that ageing begins with a single fiber and then spreads to a whole fabric. Crystallinity was one of the most effective indicators found to reveal the ageing status of silk. Therefore, a synchrotron radiation-based X-ray diffraction(SR-XRD) method was employed to study the crystallinity distribution of single fibers of ancient silk unearthed from seven archaeological sites in China from historical periods including the warring states, Han dynasty, Song dynasty, and Ming dynasty. In comparison, the conventional X-ray diffraction method, which uses large amounts of samples, was also performed to determine the integral crystallinity of ancient silk. Thermal stability experiments by thermogravimetry(TG) as well as morphology observations by scanning electron microscopy(SEM) and optical microscopy(OM) all confirmed the deterioration of ancient silk. Moreover, the ageing mechanism of ancient silk was proposed with the assistance of an artificial ageing study. The results confirmed the effectiveness of SR-XRD as an ageing indicator, revealing the crystallinity distribution. This research could provide motivation to determine the deterioration status of ancient silk, and would also aid in explaining the fragility of ancient silk due to ageing.

Whilst archaeological evidence for many aspects of life in ancient China is well studied, there has been much less interest in ancient infectious diseases, such as intestinal parasites in past Chinese populations. Here, we bring together evidence from mummies, ancient latrines, and pelvic soil from burials, dating from the Neolithic Period to the Qing Dynasty, in order to better understand the health of the past inhabitants of China and the diseases endemic in the region. Seven species of intestinal parasite have been identified, namely roundworm, whipworm, Chinese liver fluke, oriental schistosome, pinworm, Taenia sp. tapeworm, and the intestinal fluke Fasciolopsis buski. It was found that in the past, roundworm, whipworm, and Chinese liver fluke appear to have been much more common than the other species. While roundworm and whipworm remained common into the late 20th century, Chinese liver fluke seems to have undergone a marked decline in its prevalence over time. The iconic transport route known as the Silk Road has been shown to have acted as a vector for the transmission of ancient diseases, highlighted by the discovery of Chinese liver fluke in a 2,000 year-old relay station in northwest China, 1,500 km outside its endemic range.

Yifangleiju is a collection of medical books that consists of 266 volumes. It is a very important set of data in studying ancient Asian medicine because it systematically organized the many medicine-related data of Eastern Asia. But it was never published again after its 30th volume was published in 1477, and only a single copy remains in Japan today. Because this book is valuable it has been republished in China based on the copy in Japan. This study is a study of the many problems that occurred in the process of republishing Yifangleiju in China.

China has countless ancient books that contain thousand years of continuously recorded history across every generation. It is essential to organize the ancient cultural literature in order to better communicate. The study of ancient Chinese literature recently has become a subject of priority. Shi-Ji, one of the representative documents, is used for record keeping because of its experience with ancient Chinese historic materials and artifacts. This draft of Shi-ji is based on ancient Chinese research methods with the purpose to explore the character, phonology, syntax, exegesis and collation of historical value.
