This study is on the formation and the development process of urban space by referring to the literature in Yeosu where is the important location in logistics & transportation and maritime since the Japanese colonial period. There are many factors and results of the development process in Yeosu by the opening port, railroads, loads and industries. The purpose of this study is to understand the characteristics of the formation process of urban space and the characteristics of physical space in Yeosu. The results are as follow; The urban formation and development process in Yeosu where was a small fishing village in the 1910s is largely divided into four processes. Formation: the population increased due to constructions such as of a railroad, a port, and roads and there were many reclamations around the center of the old city center in the Japanese colonial period. Stagnation: There was no urban development due to stagnation, war, and the Yeo-sun Incident. Expand: the industrialization of the Yeocheon Industrial Complex and Gwangyang Steel and other areas around Yeosu led to a surge in Yeosu's population. To cope with this, the city was expanded through three land readjustment projects and the development of large-scale residential complexes. Decline and Remodeling: Yeosu's urban space declined due to the decline of fisheries and the decrease in marine and railway logistics. And the expansion and improvement of the transportation network for hosting the Yeosu World Expo increased the accessibility of the old city center, transforming it into a tourist city using cultural heritage and nature.

Multi-port HDPE and Paraffin firing tests are conducted for hybrid gas generator application of a ducted rocket in the low oxidizer mass flux range. A fuel rich gas of O/F ratio from 0.3 to 0.8, a typical O/F operating range of a ducted rocket gas generator, have been achieved with paraffin fuel implying that the hybrid system can be a potential candidate. It was also found that an almost constant O/F ratio regime exists under $35kg/m^2s$ of the oxidizer mass flux, opening a possibility for the paraffin fuel toward the VFDR gas generator application.

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.

Bareboat Charter Register or Dual Registration under a Demise Charter scheme, does not in fact sanc-tion the alternative use of flags of different states, but rather it authorises the use of the flag of the coun-try where the ship is temporarily flagged only. Bareboat Charter Register is not intended to miselead third party states or persons dealing with the ship in respect of its nationality. Bareboat Charter Register gives a shipwner a more flexible and attractive package, for example mortga-ging facilities might be more attractive in one state because of its stronger laws relating to recovery of liens, whereas the manning requirements might be attractive in another state. By using Bareboat Charter Register, a shipwner/manager can avail himself of both advantage instead of settling for a compro-mise. Ships on a Bareboat charter Register would be subject to the safety, manning and anti-pollution require-ments of the second flag state and would carry that state's right to fly a flag of the original state be withd-rawn and the effect is to suspend the registration during the period of demise charter except in so far as relates to Title transactions.

This study analyzed the fabrics of Chima, Jeogori of the 20th century. It was based on Kyungwoon Museum relics, newspaper articles and photographs. This research focused on the transition process that has been organized into three stages. The first stage is from the opening of a port to the colonial period in Korea. By this time, the casual wear Hanbok was made with the traditional cotton and woolen textiles in addition to quite a lot of upscale clothing textiles. Stage two is from 1970s to the period after the liberation and Western Costumes represent the time of when the suit was mixed. At the time of the war, due to social and economic difficulties, convenience and practicality were emphasized rather than focusing on aesthetic characteristics. Third period is from the 1980s to the 1990s when the Hanbok was no longer considered a casual wear. Instead, its high quality and elegance redefined it to be a formal wear.

The Sijeon (Licensed Markets) legally permitted by the government along the Jongno and the Namdaemunro Avenues played a central commercial role in Hanyang. However, after the opening of the port in the late Joseon era, the Licensed Markets suffered a blow and declined due to the introduction of a new product of civilization and the appearance of foreign merchants. Although the Licensed Markets, which have been maintained without major changes for a long time, have played a major role in the urban spatial structure, the exact location has not been still determined, and researches until now has remained limited for such that. In this study, based on the 1912 land survey records, the location of the Licensed Markets pre-and post- 1910 is identified, and the spatial change of the dismantling process is investigated.

For the purpose of development of high performance gasoline engine, the design technique of the 5-valve(3 intake valves) combustion chamber for a subcompact vehicle has been studied. 3 intake valves cylinder heads were designed by using a 3-dimension CAD program, and steady state flow experiments have been performed with these model. The 5-valve engines, which have larger valve opening areas, have larger intake flow rates and higher flow coefficient than the 4-valve engines. The effects of intake port design parameters of a 5-valve engine on the intake flow rate and bore size were studied, and the design guidelines for the 5-valve engine were established.

In the meantime Korean Insurance Industry has been developed a steady growth under government's political protection. But insurance market seems to be opened unavoidably owing to the liberalization of international trade by the Agreements of UR and the bloc of economy by EC Integration and the Organization of NAFTA. By the above reason, especially, in case of hull insurance, the rate of hull insurance is being instituted as a problem. Accordingly the recognition for the problem like this, in thsi study, explained the major objectives of rate making and described the basic rate making methods that are used in property and liability insurance, and searched the rate making schemes of hull insurance rate of the major nations by comparing method. And as a conclusion, the writer presented several schemes including new rate making scheme of hull insurance rate and the security of statistical data about loss ratio, and the establishment of Korean Hull Insurance Association.

Ami-dong Crematorium in Busan was established as one of the public facilities in 1929(the period of Japanese Occupation). It is the originator of Busan Yeongnak-Park(永樂公園), the funeral facilities of Busan municipality. The crematorium of Busan region was accepted at an earlier stage inside Japanese Concession in accordance with the opening a port. As Ami-dong Crematorium was constructed as a public facilities, the precedent has been maintained so far, providing a background equipped with the leading public corporation facilities in Busan area. This study was based on the expansion construction document founded by National Archives in Korea. Above all things, this research revealed the establishment and change of Busan Ami-dong Crematorium as the historical point for the formation process of recent public funeral facilities.

The purpose of this paper is to implement a guidance system for an object on the road. A watch camera equipped on the auto door recognizes the direction for the destination of an object, after that it determines whether opening or closing the door, and then the door is opened automatically, based on the decision. The motion of the moving object is approximated by using the technique of the image processing of tracking images and the affine model. The direction of the moving object is predicted from image information obtained by applying linear Kalman filter to the motion estimation in order to reduce the search region, the moving position, and the direction of the center of the object. Along with the guidance function, the system has the announcing function to the object. The experimental results confirm the veridity and applicability of the proposed system.
