The commerce and industry of Busan was developed because of good geographical conditions with harbor. After passing its settling-down and diffusing time, Busan has grown in the trade city. Busan has lost the competitive power of the port city since 2000, because of the weakness of its economic power which is caused by the secession of manufacturing industry and the decrease of resident population and foreign tourist. In order to overcome these weaknesses, it is necessary for Busan to take the innovative strategy for the activation of marine tourism. This goal can be achieved by the strong quality of the port city, the coastal terrain, the traditional industry and the international traffic. The aim of this paper is to explore the Innovative Strategy for the activation of marine tourism in Busan and to suggest the following proposal. First, the government must decide the base of marine tourism under the geography viewpoint of the coast and sea, and develope tourism resources after analyzing the identity of marine tourism base. Second, the core part along the selected bases of marine tourism must be constructed the tourism terminal as the landmark of Busan in order to concentrate foreign tourist. Third, after each base of marine tourism must become the resort for tourists, they are able to experience the activity of marine tourism in this resort. Therefore, each base must be specialized. Fourth, each base must be connected with the route of marine tourism Fifth, in order to overcome the off-season of marine tourism, winter tourism goods such as skates, skis, artificial sea-bathing pool, artificial swimming beach, artificial sled, artificial rock wall of coast, hot spring resort of salt water are required to be developed in the center of marine tourism base.

Recently dredged material generation has a tendency to increase since harbor construction are under progress. In this study, an experiment had been carried out which replacement of dredged material of Busan and Ulsan port as concrete mixing material. For this experiment, physical and chemical test of dredged material was carried out, and compressive strength test of mortal specimen with dredged material in scale, as aggregate replacement, was carried out. Compressive strength of Busan and Ulsan was both increased when the ratio of mixing materials was 10%. Compressive strength of Dredged material from Busan with about 70% of mineral silt showed increse when the ratio of aggregate replacement in 30%. In addition, in the result of the ICP test, both dredged materials satisfied the waste's marine discharge treatment and soil contamination concern and measures criterion on that using dredged material as a concrete material can influence on application of concrete positively.

We studied the characteristics of marine casualties within the area under control of Korea National Maritime Police and leeway of drifting vessel. According to 5 years＇(1995~1999) data of casualties, it was found that the occurrence of casualties by fishing boats ranked the highest and a considerable numbers of casualties took place more than 20 miles off the shore. From a result of field experiment of G/T 50 tons vessel off Busan harbor on Apr. 26~28, 2000, we computed that the linear equation of leeway speed(cm/s) was 1.01$\times$U(U : wind speed in m/s)+11.36 with correlation coefficient between wind speed and leeway speed being 0.252 and we found leeway angle range from $+87^{\circ}$(right) to $-78^{\circ}$(left ) of the downwind direction.

The purpose of this research is to develop the method for the beneficial use of dredged material. In this research, authors investigate the material properties of dredged material contained with dredge material of various contents. The compressive strength of cement mortar with 10% dredged material from the Busan harbor is slightly higher than it of conventional mortar, but, it is to need to further research for developing the application technique on the dredged material as the substitutional material of a sand.

As the quantity of transported goods increases, there is a lot of mechanical trouble with loading facilities. So it tremendously produces not only economic loss but also time loss. To reduce the loss from the trouble of leading facilities, it is necessary to analyse the distribution of the problem's occurrence and use the analyzed data to minimize the outbreak of trouble. So the data can be usefully used when designing or manufacturing and it also can be utilized for proper maintenance of operating equipment, frequency of inspection and repair, know-how of checking on equipment and purchasing of spare parts. And it is possible to minimize the loss if the propel maintenance is adapted

In the past, the predictions of beach processes and harbor sedimentation were mainly relied on the hydraulic model tests and empirical methods. In recent years, however, as computers have come into wide use, more accurate models have gradually been developed and thus replaced those conventional methods. For prediction of topographical change near the coastal area.

Recently, a perforated caisson breakwater with turning wave blocks was developed to improve the water affinity and public safety of a rubble mound armored by TTP. In this study, hydraulic model tests were performed to examine the hydraulic performance of a non-porous caisson and new caisson breakwater with perforated blocks for attacking waves in a small fishery harbor near Busan. The model test results showed that the new caisson was more effective in dissipating the wave energy under normal wave conditions and in reducing the wave overtopping rates under design wave conditions than the non-porous caisson. It was found that the horizontal wave forces acting on the perforated caisson were slightly larger than those on the non-porous caisson because of the impulsive forces on the caisson with the turning wave blocks.

In approaching sea area of Busan harbour, there are many traffic vessels and external forces such as strong seasonal wind and lateral flow are existed. Since the area caused the risk of navigation and ship operators feel hard to enter/depart on Busan port, we carried our the evaluation of traffic risk and propriety at Busan no.1 fairway. In order to assess the safety in the fairway, we analyzed ship's traffic stream based on the marine traffic survey and evaluated the traffic safety of present Traffic Separation Schemes(TSS) and suggest TSS in the research using full mission ship-handling simulators. As a result, the suggested TSS has an effect on improving the traffic safety. In addition, this paper was to suggest the dredging area of depth of water, the passage of towing vessels and control of warships for preventing of maritime accidents in the Busan no.1 fairway.

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.
