This paper is aimed that preparing to make good plan for great city ports, like Gwangyang port which is growing rapidly in Asia as a hub port. But I am worrying about the capacity of Gwangyang bay area to serve very great mission for the future, continuously. I hope that we are able to make good circumstances for our great ports. In this Gwangyang bay, we can realize that we may have some solutions for the traffic jam, because of the finite bay area. So I analyzed the rate of traffic jam that was derived from so many great ships to come and use the Gwangyang bay area. As a result, in recent year, 2005, 2006, ratio was growing rapidly, so we need so we need good works for this region.

Marine traffic safety of the Vung Tau Waterway, from port limit to Ganh Rai Gulf, plays a crucial role in the economic development of the important triangular economic zone in the south of Vietnam: Ho Chi Minh City, Dong Nai Province, Ba Ria-Vung Tau Province. This paper uses the IWRAP Mk2 program to assess marine traffic safety and shows that in the area there are three parts of fairway have highest risk of collision (from buoys No. 8-9 to buoys No. 1-2 of the Song Dinh fairway; from buoy No. 0 to buoys No. 8-9 and from buoys No. 6-9 to buoys No. 8-9A of the Sai Gon-Vung Tau fairway) and the two areas have highest risk of grounding (the Vung Tau coastline from Ganh Hao to Sao Mai and an area in the Ganh Rai Gulf). In addition, the result of a questionnaire survey on a group of Pilots shows that wind, current and rain/fog have considerable negative effect to ship handling of large vessels in this area. This paper's results will be used in the further research to discover solutions for improving marine traffic safety in the Vung Tau Waterway.

Recently it was known that the problems of nearshore processes and damage of berth and counter facilities frequently had appeared at the small fishery port, such as Daebang near Samcheonpo city, Korea. Here we try to analyze the impact of the rearrangement of counter facilities and berth layout adopted for tranquility of its inner harbor. Because this harbor is being connected to Daebang channel, the rearrangement of the structures might affect to the current speed and direction and wave height, so do to the sea bottom undulation. Therefore, we made model test for the several layouts of the berth and breakwater in this area. Numerical model result shows that the bottom was eroded by 1m by tidal currents and the speed of flow did not shrink, even after the construction work was completed. The direction of the sand movement was downdrift. Although the model study gave reasonable description of beach processes and approach channel sedimentation mechanism, it is necessary to compare with the field history, including the records of waves, tides and bottom materials, etc. for better prediction.

Because of the heat island phenomenon and sea wind, there can be thermal conditions' differences around buildings at downtown and coastal area respectively in coastal city, like Busan, Incheon, Mokpo. For the final purpose of the buildings' energy saving design and operation considering of above mentioned environments differences, energy consumption including heating and cooling loads, electric loads are necessary to be accumulated and analyzed in as the database. As a part of this concept, this study aims to survey and analyze each loads of 22 apartments which has at least 100 households respectively and is located at Yeongdo island, Busan, Korea It is cleared that despite the residents living in this district can use sea wind as a natural ventilation and/or cooling methods, they mainly depends on the electric-driven air-conditioners for cooling with window-closed because of anti-salt problems of the sea wind. This leads the maximum power consumption of the surveyed-22-apartments to be appeared in August like that of inland buildings.

The geological survey of the Mokdo island is for the fist time conduted in Korea history. The island had erupted before $70{\sim}80$ million years as a strato-volcano. The original volcano had been dissected for long periods up to the skeletal stage through the planeze stage. If the island area is surveyed afterwrds in detail, the position of crater is available to be found, either. The coastal terrace is found at 50m level in Mokdo island which is correlated to its fourth plane. The microgeomorphological features as coastal terrace, cliff, sea cave, wave-cut bench, sea stacks, notch, and tafoni, etc. were described. The Mogdo island is located off Molundae at the extension of Nagdong Jeongmaeg(낙동정맥 洛東正脈) showing a "floating turtle". The name of Mogdo island is needed to change to the "Yoo-goo-do" which means the swimming turtle. The Mokdo island is as suitable tourist attraction for if has enough touism sesouccesein sea. The deuelopsment of coartal sightseeing anound lighthoure and uninhabited islands will hare an impontant effect upon construction of the oceanic capitol city of Busan Haabor. The master plan built up an arboretum on the island, a coastal oceanarium, a seaweeds garden under sea coast, and other oceanic culture-spaces is completed in the study.

Purpose: The purpose of this study is to propose a direction planning integrated waterfront cultural city in terms of urban economic revitalization through regeneration of former industrial harborfront and the creation of cultural living spaces based on regional history in order to pursue urban activities. Method: Analyzing planning waterfront and historical cultural space based on MM21's development policy and strategy under the growth process and development of Yokohama. Results: MM21 is the core public project out of the six major projects promoted by Yokohama, which is on the brink of satellite cities for the expansion of Tokyo with a goal of qualitative transformation of former harbor. It is planned to be developed as a creative cultural waterfront city for an integrated urban development. Conclusion: Planning waterfront cultural city, which takes advantage of the former harbor city derived through MM21 analysis, provides the cityscape towards the sea and the port via the viewing point and opens the waterfront open to the port and the sea Space and Esplanade landscape development, preservation of historic buildings and cultural assets, recycling as cultural art space, waterfront space planning that cooperates with public culture art and pedestrian network.

How does the youth feel the sea affairs\ulcorner Concerning this question, this paper aims to measure the images of the youth toward the sea affairs - the sea, the ship and the seafarer and to examined the above subject. As sample 3, 250 students of middle and high school were selected by considering geographical environment. The data obtained using Semantic Differential Method were analyzed by principal component analysis, and the obtained factor scores were examined the significance of difference between sex, age and geographical environment. By introducing the principal component analysis, the authors extracted from each of the images, that is, factors of dynamics and affection to the image on these a and the former the factors and pleasure on the ship, and also the former two factors and factor of professional evaluation on the seafarer, The following results are obtained. 1) In the image of the sea, dynamic image of the student in high school were higher than the of the student in middle school in spite of geographic environment and affective image were opposite. 2) In the images of the ship, affective image of the student in middle school and high school in inland were high than the of the male and female student in near the sea. And also, male female students in middle school and male student s in high school of inland showed the highest score to the pleasure image. 3) In the image of the seafare, professional evaluation of the female student in middle school were higher than the others, but the students in high school showed the highest score to dynamic image. Especially, in the case of the majority of students in high school living in the city or town near the, their images of the seafarer were not so good in spite of their explorative experiences about the sea affairs.

In this paper, based on evidence of coastal sediment, we show that erosion and sedimentation environments are very sensitive to sea level changes during the Medieval Warm Period (MWP) and the Little Ice Age (LIA). We identified four sedimentary units(4.57-3.07m), which formed in the Dark Age Cool Period (DACP), MWP and LIA were classified based on the lithostratigraphy, grain size distribution, magnetic susceptibility and geochemistry of a drilling core taken from the west coast of Hwaseong City. The unconformity surfaces as boundaries of the units were also identified by the lithostratigraphy shown on the drilling core. We propoese that sedimentation was dominant in the area during the periods of sea level rise, whereas erosion prevailed during the periods of sea level fall. Particularly, extreme events, such as floods and typhoons are believed to have accelerated these processes, and we found the associated evidence in sediments of two units. This study provides an example of estimating the relative sea level variation using coastal sediments and may be useful for studying past sea level changes around the Korean Peninsula.

This study will define the features of the viewpoint that best enables the view of Busan Port from Young-Do. Special focus will be on spatial distribution, the type Busan Port sights that can be experienced from Young-Do, the compositional characteristic of a port landscape and visual characteristic. The results are based on 27 selected viewpoints and are as follows. Firstly, the patterns of the spatial distribution of viewpoints are classified as park, public facility and wayside types. It was found that most viewpoints are located along a wayside. Secondly, the types of Busan Port sights that can be experienced from Young-Do are divided into three kinds: surrounding stand-line type, facing the port and the type of penetrating city. The major type was of penetrating city among the three patterns. The reason for this is that the point of view for Busan Port was changed into a prospect over the sea since city and road sections have been expanding due to the urbanization of Young-Do. Thirdly, the compositional characteristics of the port landscape are divided into three styles: panoramic, corridor, and rooftop. The most frequent type is the rooftop style among the three characteristics. This fact indicates that the picture of Busan Port seen from Young-Do loses continuity of view and that housetops inhibit the sense of distance. Lastly, the visual characteristics of the viewpoint were analyzed. The angles of the declination of the viewpoints are concentrated on the horizontally closed parts. Thirteen points lie between $-3^{\circ}$ and $-1^{\circ}$, and twelve points between $-6^{\circ}$ and $-4^{\circ}$. The visual axes of the depression are two points because sight is interrupted by buildings which are built when the city expands. Two viewpoints for experiencing the optimum landscape of depression should be prepared to ensure continuous preservation of the viewpoints. The sight creates a wide prospect, reaching from 0.2km to 6.4km. It is expected that the results of this study can be used for the landscape plans of port cities including the management and preservation of viewpoints.

In recent years, the rate of mean sea level rise is increasing rapidly from the phenomena of global warming, together with the increasing trend of the storm scale. The issue of sea level rise is multifaceted and produces a range of environmental problems. Especially, high tides and the tidal currents become higher, and wave base increases, so the energy received at the coastal boundary may increase. This brings that many coastal environments go into disequilibrium, such as damages to the structures, erosion, and deposition Similarly it was known that the problems of nearshore processes and damage of berth and counter facilities during storm period had appeared at the small fishery port. Here we try to analyze the impact of the rearrangement of counter facilities and berth layout adopted for tranquility of its'inner harbor. Because this harbor is being connected to channel and open sea, the rearrangement of the structures might affect to the current speed and direction and wave height, so do to the sea bottom undulation. Therefore, we made model test for the several layouts of the berth and breakwater in this area.
