1990년대 이후 세계경제흐름의 한 가지 특징으로 개방화 및 지역경제통합의 확대를 꼽을 수 있다. 이로 인해 세계경제권은 유럽연합(EU)을 중심으로 하는 유럽경제권, 미국을 중심으로 하는 아메리카 경제권, 그리고 최근에 급부상하고 있는 중국을 중심으로한 동북아 경제권이라는 삼극체제로 재편되고 있다. 이러한 세계경제의 조류와 동북아의 현실 그리고 사상 최대의 항만개발 프로젝트를 수행하고 있는 중국과 자국항만의 경쟁력 회복을 위해 획기적인 항만정책을 도입하고 있는 일본의 움직임 상황을 감안할 때 우리나라도 이에 대한 선도적, 능동적 대책마련이 절실하고 시급한 과제라고 사료된다. 본 연구는 문헌연구의 방법을 통해서 먼저 Hub-Port의 개념과 조건을 제시하고, 동북아 경쟁국의 Hub-Port 발전전략을 논술하며, 이를 위해서 부산항과 일본의 혼슈(시모노세키항)와 규수(키타규수항) 사이에 위치하는 한 일해협경제권의 발전 잠재력과 전략적 협력을 통한 한 일 공동 발전을 모색하는 것이 본고의 목적이다.

In Korea, the System of search and rescue in water have came into force on the basis of the Korea Life Saving and Rescue Act. 1961. But It's a premodern administration law which is not fit for an international system of the search and rescue and become disconnected with reality in Korea. Recently the marine casualties occur frequently in Korea coastal area, therefore, we need to amend the 1961 Act. The amendment which is carried out by the Korea Maritime Police Agency is a provision to receive International convention(SAR, 1979). The amendment of this Act will give a epoch-making change to Korean policy of the life-saving and rescue, security to marine safety and contribution to National positon on system of "Search and Rescue". In this thesis, I propose a development scheme to be conductive to original task on "Search and Rescue" of International Convention in Korea Life Saving and Rescue Act(Amendment, 1994).t(Amendment, 1994).

Incheon Bridge, 18.4 km long sea-crossing bridge, will be opened to the traffic in October 2009 and this will be the new landmark of the gearing up north-east Asia as well as the largest & longest bridge of Korea. Incheon Bridge is the integrated set of several special featured bridges including a magnificent cable-stayed girder bridge which has a main span of 800 m width to cross the navigation channel in and out of the Port of Incheon. Incheon Bridge is making an epoch of long-span bridge designs thanks to the fully application of the AASHTO LRFD (load & resistance factor design) to both the superstructures and the substructures. A state-of-the-art of the geotechnologies which were applied to the Incheon Bridge construction project is introduced. The most Large-diameter drilled shafts were penetrated into the bedrock to support the colossal superstructures. The bearing capacity and deformational characteristics of the foundations were verified through the world's largest static pile load test. 8 full-scale pilot piles were tested in both offshore site and onshore area prior to the commencement of constructions. Compressible load beyond 30,000 tonf pressed a single 3 m diameter foundation pile by means of bi-directional loading method including the Osterberg cell techniques. Detailed site investigation to characterize the subsurface properties had been carried out. Geotextile tubes, tied sheet pile walls, and trestles were utilized to overcome the very large tidal difference between ebb and flow at the foreshore site. 44 circular-cell type dolphins surround the piers near the navigation channel to protect the bridge against the collision with aberrant vessels. Each dolphin structure consists of the flat sheet piled wall and infilled aggregates to absorb the collision impact. Geo-centrifugal tests were performed to evaluate the behavior of the dolphin in the seabed and to verify the numerical model for the design. Rip-rap embankments on the seabed are expected to prevent the scouring of the foundation. Prefabricated vertical drains, sand compaction piles, deep cement mixings, horizontal natural-fiber drains, and other subsidiary methods were used to improve the soft ground for the site of abutments, toll plazas, and access roads. Light-weight backfill using EPS blocks helps to reduce the earth pressure behind the abutment on the soft ground. Some kinds of reinforced earth like as MSE using geosynthetics were utilized for the ring wall of the abutment. Soil steel bridges made of corrugated steel plates and engineered backfills were constructed for the open-cut tunnel and the culvert. Diverse experiences of advanced designs and constructions from the Incheon Bridge project have been propagated by relevant engineers and it is strongly expected that significant achievements in geotechnical engineering through this project will contribute to the national development of the longspan bridge technologies remarkably.
