Although there are a lot of primary factors to be able to make characters and identities in Pusan South Harbor, Badly Planned development prevented enhancing the sense of place in urban waterfront. The point in the waterfront development is how to secure amenities based on indentity and orientation; node, landmark, edge, path, district. This study aims at developing waterfront area of Pusan South Harbor and attempting to establish an identity through studying characteristics of ‘places’ in Pusan South Harbor. The place consists of two elements; orientation and identity, which can be explained the environmental totality, ‘character’ and ‘space’ respectively. The urban waterfront has strong characteristics which consists of land area, water area, and transit zone combining two areas. The place of Pusan South Harbor is analysed those four elements. We proposed objectives and criteria which can be used in enhancing the sense of this place.

A new concept sea-floating port called mobile harbor has been introduced, in order to resolve the limitation of current above-ground port facilities against the continuous growth of worldwide marine transportation. One of important subjects in the design of a mobile harbor is to secure the dynamic stability against wave-induced excitation, because a relatively large-scale heavy crane system installed at the top of mobile harbor should load/unload containers at sea under the sea state up to level 3. In this context, this paper addresses a two-step sequential analytical-numerical method for analyzing the structural dynamic response of the mobile harbor crane system to the wave-induced rolling excitation. The rigid ship motion of mobile harbor by wave is analytically solved, and the flexible dynamic response of the crane system by the rigid ship motion is analyzed by the finite element method. The hydrodynamic effect between sea water and mobile harbor is reflected by means of the added moment of inertia.

An accurate estimation of water level variation when thewaves propagate to the coastal regionis very important for the port and harbor development plan. This study describes the application of a hybrid element model to harbor oscillation problem due to the construction of shore structure and implementation of shore boundary. The site selected is Pusan Harbor area with the third development and the Artificial Island plan. The observed water level changes at the site are compared with the result of the numerical experiment. The model gives a very important prediction of water level changes for navigation and harbor design.

부산항 해역의 지표성 요각류의 분포 및 11∼22개의 분류군에 속하는 동물플랑크 톤 군집을 다양도 및 집괴분석으로 분석하였으며 이들 생물학적 결과를 수온, 염분, COD, TIN의 분포와 연관시켜 부산항 해역의 해양환경을 고찰하였다. 네 무리의 요각류 들이 출현하였으며, 이들은 난류성 외양종무리인 Acrocalanus gacilis, Euchaeta plana, pareuchaeta russell and Pleuromamma gracilis 연안성 저온종인 Centropages abdominalis, 한류성 종인 Metridia lucens, 오염지표종인 Acartia omorii였다. 부산 항 외항의 경우, 10월에는 난류 외양성 종들이, 1월과 4월에는 연안 저온성종들이 우 세하였다. 내항으로 접근할수록 오염지표종인 Acartia omorii의 분포가 우세하였으며 COD 및 TIN의 분포 또한, 외항에서 내항으로 가면서 높아지는 경향을 나타내었다. 반 면에 다양도는 외항에서 내항으로 가면서 낮아지는 경향을 나타내었다. 집괴분석에서 10월과 7월에는 3개의 해역으로 그리고 1월과 4월에는 2개의 해역으로 나뉘어졌다. 해 역 I로 대벌되어진 부산 외항 해역은 외양수의 영향을 받는 해역으로 다양도가 높으 며, A. omorii의 밀도가 낮고 요각류의 조성률이 높게 나타났다. 외항에서 내항으로 가면서 대별되어 진 해역 II와 III은 해역 II에서 III으로 가면서 점차적으로 다양도 가 낮아지며, A. omorii의 밀도는 높아지는 특성을 나타내었다. 또한, 요각류의 조성 률이 낮아지며, 4월에는 해역 II에서 원생동물인 Noctiluca scintillans가 최우점군이 였다. 그리고 7월에 해역 III에서는 지각류가 취우점군이였다. 지표성 종들의 분포와 집괴분석에서 나뉘어진 해역은 해양 환경과 밀접한 관계를 나타내었다.

This study aims at advancing waterfront planning and development of North Harbor of Pusan and attempting to establish an identity through the analysis and case studies of waterfront development of foreign countries. This study is based on Pusan urban harbor plan and the case study which was investigated the relational port with an urban area to find a model of development method and procedure of urban waterfront renewal, The approach of this study is to classify diversified cases and to suggest elements after reviewing successful cases. The point in the waterfront development plan of North Harbor of Pusan is how to secure an amenity on the edge and provides a comprehensive theoretical base such as skyline, coastline, green area, accessibility, scenery, landmark, open space, and so on. The result of this study is useful for the planner to develop more and systematic approaches which could utilize waterfront. Waterfront development will be a new chance of urban development for Pusan.

This paper reports the results obtained for there flection and transmission coefficients on rubble mound breakwaters in Busan Yacht Harbor. A2D physical model test was conducted in the wave flume at the Coastal Engineering Research Laboratory at Pusan National University, Busan, South Korea. In this study, physical model tests were completed to further our understanding of the hydrodynamic processes that surround a rubble mound structure subjected to irregular waves. In particular, the reflection and transmission coefficients, as well as the spectrum transformation, were analyzed. This analysis suggests that with an increase in wave height around a rubble mound, the reflection coefficient drastically increases at each water level (HHW or MSL or LLW). Moreover, when the water level changes from HHW to LLW, the reflection coefficient is suddenly reduced. A further result of the analysis is that the transmission coefficient strongly drops away from the rear of the structure. Finally, in regard to the rubble mound breakwater in Busan Yacht Harbor, a consideration of the reflection and transmission coefficients plays an important role in the design.

To prevent increasing instances of heat-related illnesses due to heat waves generated by climate change, a customized thermal environment index should be developed for outdoor workers. In this study, we conducted sensitivity analysis of the Masan harbor during a heat wave period (August 9th to 15th, 2013) using the MENEX model with metabolic rate and clothing-insulation data, in order to obtain realistic information about the thermal environment. This study shows that accurate input data are essential to gather information for thermophysiological indices (PST, DhR, and OhR). PST is sensitive to clothing insulation as a function of clothing. OhR is more sensitive to clothing insulation during the day and to the metabolic rate at night. From these results, it appears that when exposed to high-temperature thermal environments in summer, wearing highly insulated clothing and getting enough rest (to lower the metabolic rate) can aid in preventing heat-related illnesses. Moreover, in the case of high-intensity harbor work, quantification of allowed working time (OhR) during heat waves is significant for human health sciences.

The purpose of this study is to develop a stacking guidance system (SGS) of containers in the mobile harbor (MH). A mobile harbor is a floating structure especially designed for loading and unloading containers from and to a large container ship. A novel stacking guidance system was proposed for unloading the container in an effective way against possible vibrations of the floating body. The guidance system works as an aid for loading containers with a wider opening for easier stacking of a container into a moving storage cell due to waves. In order to determine the most effective inclination angle of the cell-guide, this study performed the dynamic analysis of the SGS equipped in the MH subject to fluctuations of the sea. The motions of the guidance system and a container loaded were calculated using ADAMS. The simulation results of the contact force between the two rigid bodies showed that a desirable angle of the cell-guide should be around 20 degrees from the vertical. This proposed SGS can considerably reduce the loading and unloading time, and will enhance the performance of the MH.
