In according to the rapid economic growth and strengthening of economic cooperation of Asian-Pacific countries, Pusan is capable of developing to the international trade center of Pan-Pacific Area. Therefore a lot of functional preparations are required for the international trade center. First the expansion and functional specialization of harbor which is a gateway of international physical distribution is required. Second, raising physical distribution inducement effect through establishment of free trade zone and producing financial and information service accompanied with trade activity through establishment of international financial center and teleport are necessary. And the research complex of high technology (sciencepark) which utilizes the industrial base of Pusan area is necessary for the development of Pusan toward the international trade city. And the establishment of marine sightseeing complex in Pusan utilizing the ocean natural resource is helpful for the growth of Pusan to the international trade center.

It is very important to quantitatively assess the movement of sea water and pollutant dispersion before or after constructing shore structures such as breakwater considering marine environment and long-term utilization of those structures. This assesment is possible through the use of simulation models designed to predict water movement and pollutant dispersion in a certain area. In this study the numerical computations were carried out to predict the sea water quality in the Ilgwang Harbor located at the east coast of Pusan. The flow patters were investigated before and after the development of Ilgwang Harbor. The computational models adopting ADI Method (Alternating Direction Implicit Method) were used here and were already verified from the previous studies. As a results of this study the tidal exchange in Ilgwang Harbor after development proved to be worse due to the increased semi-enclosed at the harbor limit. In order to improve the water quality of this area after development a new method was proposed to improve water quality in the semi-enclosed bay by creation and control of tidal residual currents. For this purpose the unsymmetric structures so called bottom roughness were introduced in this study. The simulation was carried out on the basis of the study by Komatsu et. al. and Gug and we made a conclusion that it is possible to generate a new tidal residual current and to increase the tidal exchange by application of bottom roughness arrangement.

This study is about gaining orientation through anchorage act of a group of ferryman. In addition, a point acquisition and character of landmark that is closely realated to a point acquisition would be clarified by studying the form of configuration of the earth and object which is used landmark for anchorage. There are 13 anchorage points in the north part of Pusan harbor. 12 anchorage points are used to anchor. A ferryman let a ship which is temporarily anchoring move safely and speedily at the anchorage point. At that time, he uses landmarks by a technique of Overlay View. Between landmarks and viewer would be formed exquisite location combination. A mountain peak, a peak of island, nature configuration of land such as intermitent rock and location, size and form of buildings or structures of a city were variously appeared as landscape elements which were used landmarks. Looking at conditions to be easily captured as a target object, 1. A particular point of a mountain ridge line which was not shield by buildings. 2. In case objects have similar form, the building which was located in the front or the highest. 3. In case of a singular object, whatever there is physical elements, that would be a target object. Through this study a configuration of the ground such as a mountain peak which is become the background of harbor landscape is very important element to find anchorage point in configuration of the ground and object. So, the continuous preservation of the contour line of mountain is needed to do safe and effective anchorage act.

Coastlines are protected by breakwater structures against the erosion of sand or other materials along beaches due to wave action. This research examined the use of physical modeling to determine the effects of the tetrapod size and vertical walls of a rubble mound on the volume of wave overtopping under irregular wave conditions in coastal areas in Busan Yacht Harbor. In this analysis model, the structures were studied using irregular waves and the JONSWAP wave energy spectrum. To understand the effects of the tetrapod size and heights of the vertical wall, the study considered vertical walls of 0, 1.78, 6.83, and 9.33 cm with armor double layered material tetrapods of 8, 12, 16, and 20 tons. An extensive number of experiments covering a relatively large range of variables enabled a comprehensive discussion. First, in the presence of a short vertical wall, the water level played a key role in the overtopping discharge. In such circumstances, the values of the wave overtopping discharge decreased with increasing freeboard size. In the presence of a tall freeboard and middle, the value of the wave overtopping discharge was equally influenced by the vertical wall factor. Moreover, the tetrapod size decreased by an increase in the vertical wall factor, and relationship between them resulted in a short wall height. From an engineering point of view, considering a small water level may allow the choice of a shorter vertical wall, which would ultimately provide a more economical design.

This study is change of the street space of the port city of Yokohama and the transformation process of the canal. modern port city Yokohama is a region that was responsible for the development of East-West maritime transport routes in Japan in the 17th century and the inland transportation through fishing villages and ports. it has also grown rapidly as a regional port and new port. In particular, through the revitalization of trade between foreign settlements and Japanese residents in the port area, the existing fishing area became a modern port city space. Yokohama went through the following process and grew into a modern port city. The construction of the port harbor and the maintenance of existing logistics functions, the formation of the central horizontal axis through maintenance of the fishing village, the construction of the logistics movement route to the inland area through the construction of the canal, the expansion of the horizon for fire prevention and fire restoration, The formation of a new settlement space according to the movement, the transformation of the existing religious axis by the combination of the elaboration and the introduction of modern transportation, and the spatial connection between the inland cities.

This paper introduces a method that can derive information about the movement of a spreader and skew in order to drive ALS(Automatic Landing System) in the crane used at a harbor. Some methods that use LDL Corner detectors a kind of 2D Laser scanner sensor or Laser distance measuring units to obtain the information in ALS are used presently. But these have some defects in economic efficiency and performance. Therefore, to correct these defects, we propose a method to acquire the information for the movement of a spreader, skew and sway angle using CCD camera image data and Laser distance measuring unit data.

The harbor back area is not a planned space, but rather a space created by harbor space development. For this reason, the residential environment in the area behind the port has been very poor from the past to the present. Recently, the redevelopment has been increasing in accordance with the function of the port space. However, the development of the domestic port space is limited to the port space, and there is still little preparation for improvement of the residential environment in the port area. In this study, the degree of decline of the port area was diagnosed and analyzed for the purpose of deriving urban regeneration scenarios to improve the residential environment of port - backed areas. The urban regeneration factor to improve the livability of the port - backed area, which has been declining since then, was derived, and the scenarios in which each factor was applied were constructed.

It has been said from previous studies that the preconsolidation pressure (p$\sub$c/)of Nangton Rive. deposit is considerably less than the in situ effective burden pressure (p'$\sub$$\upsilon$ο/). Question has risen whether this small pc vale is due to under consolidation or unsuitable laboratory test including low small quality. As a cooperative research program between PHRI (Port and Harbor Research Institute) and Pusan National University, an extensive soil investigation was carried out at a site of Yangsan, Pusan, using the Japanese sampler. It Is found that although p$\sub$c/ value at the site is slightly greater than p'$\sub$$\upsilon$ο/, its over consolidation ratio (OCR) is quite small compared with aged normally consolidated clay in Japan.
