In this study, geomorphological and geological research has been carried out to estimate the possibility of ancient port location near Hwaseong Dangseong. Geomorphological characteristics around Eunsupo were analyzed through comparison of past and present topographic maps and field survey. Grain size, age dating, and geochemical analysis on surface sediments and borehole sediments were performed. Through the geomorphological characteristics analysis, it was interpreted that Eunsupo area was submerged in seawater especially at high tide in the past, and that ships could approach to the inside of the area through the tidal channel which were developed in the area. It is also assumed that ships were anchored at a low elevation point in the area. The paleo-environmental change in the area was analyzed based on the classification of sedimentary environment using grain size distribution of surface and borehole sediments and geochemical analysis. It was confirmed that the geomorphological interpretation for the possibility of ancient port location coincided well with the paleo-environmental change interpreted through sediment analysis. This study is a basic study for estimating ancient port location, and it is expected that more accurate paleo-environmental changes will be restored through detailed geomorphological survey and additional borehole analysis in the future research.

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 We, however, do not have many historical documents or credible materials that can our ancestors' great shipbuilding techniques : at the same time we do not have paid much attention to the research on such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.

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.

Xu-Jing(徐競) an official of the Song(宋), a medieval Kingdom of China, wrote a book titled $\ll$Koryo Tu Jing(高麗圖經)$\gg$ which explains his travel to the Koryo as a member of diplomatic mission in 1123. $\ll$Koryo Tu Jing$\gg$ is the record of his personal experience in Koryo with many explanatory illustrations and especially contains 5 months' voyage record of his diplomatic fleet. His fleet set sail at a port located in the Ding Hai Xian(定海縣), Ming Zhou(明州) via a few islands of Koryo [Hyup Kye San(俠界山) , the Kun San Do(群山島) , the Ja Yon Do(紫燕島) , the Keup Su Mun(急水門) in Kang Hwa Gun(江華郡) and the Hap Gul(蛤窟) ] and finally arrived the Port Ye Song Hang(禮成港) . According to the Xu-Jing's record his fleet sailed the sea with the help of the favorable seaward winds and tides as the usual way of ancient sailing. The Xu- Jing's Fleet sailed the sea between the Mei Cen(梅岑), Ming Zhou(明州) of China and the Hyup Kye San(俠界山) of Koryo from about 5:00 a.m., May 24th(of the lunar calendar) to about 5:00 p.m., June 2nd. At this section, the average speed of the seaward winds was 19.45km/h and the average speed of the fleet which sailed only by the power of the winds was 6.29km/h. This means that 32.3% of the favorable seaward winds' speed was equal to the speed of the ancient fleet which sailed only by the power of the favorable seaward winds. The fleet sailed the sea between the Ja Yon Do(紫燕島) and the Keup Su Mun(急水門) from about 9:00 a.m., June 10th to about 1:00 p.m., the same day. At this section the fleet sailed by the power of tides in addition to the favorable seaward winds without oaring. The average speed of the winds was not different from that of former section and the average speed of the tides was 1.937km/h. And at this section the average speed of the fleet increased by 0.41km/h than that of the former section. This means that 21.1% of the speed of the tides was equal to the increased speed of the ancient fleet by virtue of the tides. The fleet sailed the sea between Keup Su Mun(急水門) and the Hap Gul(蛤窟) from about 1:00 p.m., June 10th to about 3:00 p.m., the same day. At this section, there were no seaward winds and the fleet sailed only by the powers of tides and oaring. And at this section, the tide increased the average speed of the fleet by 0.3114km/h and the fleet could sail at the speed of 4.3km/h. So we can conclude that the average speed of ancient fleet without any influences of the seaward winds and tides was 3.98 km/h. We can make use of the various sailing speeds of ancient fleets when judging their maritime activities. If we make use of the various sailing speeds of the ancient fleets as calculated in this article, we will be able to get various important informations about the certain ancient fleet's maritime maneuver. For example, we can infer the sailing routs of a certain fleet and the time when the fleet passed a certain spot by making use of the various sailing speeds of the ancient fleet. In this article I did not take account of the shapes of ships that consist of the ancient fleets and the sizes of the various ships and fleets. It was because that such factors would not change the foresaid conclusions seriously.

India has occupied the most important position of sea trade in the entire South Asian region since the beginning of maritime trade. The extensive maritime trade network between the Harappan and Mesopotamian civilizations as early as the $3^{rd}$ millennium BCE is testimony to the long maritime trade history of India. The Harappans constructed many seaports including the first high-tide dockyard in the world for berthing and servicing ships at the port town of Lothal, Gujarat. From the dawn of the historical epoch, the maritime trade network of India expanded extensively. The long 5422.6 kms coastline of the Indian mainland (excluding the coastlines of the Andaman and Nicobar islands and the Lakshwadweep Islands) is well known for its several seaports manly located at river mouths or outlets to the sea. The main objective of this paper is to discuss in detail all the major ancient seaports on the eastern coast of India and their maritime trade activities. The narrative of these ports is based on archaeological explorations and excavations, foreigners' accounts, Indian literary sources, inscriptions, archival materials, and the field study and personal observation of the author.
