Recently, Green Port project to develop an environment-friendly port is active to lead by Port of LA, Port of LB in the USA and Port of Rotterdam. While, Port of Singapore, Shanghai Port and Dubai Port are trying to be a complex Port to function as a true portal not only for freight, but also for people and information. Ports, in this era, doesn't just play a simple transportational role for passengers and freight. Ports in this 21st century, play a role as a center where passengers, freight, information and money gather and a place where freight is created from nearby supporting area. Therefore, this study intends to draw action plans for Port of Busan to grow as Complex Port in the 21st century by AHP analysis and evaluate the action plans of each field by quantitative factors (business portion in the area/specialty/synergy effect with other industry) and qualitative factors (potential for future growth/competitiveness/ capability for innovation). The evaluation result can be used as basic information to decide business priority.

This study aims at improving Korea's competitiveness in port logistics through marketing strategy with integrating the conceptual approach into the empirical one and combining both the oldest military treatise and the newest evaluating model in social science that was applied by the HFP(hierarchical fuzzy process) model enhanced by the KJ method. The empirical results of this study show Busan in the middle among subject ports. At present, Korea plays a reciprocal role in the port market in East Asia, but in the medium- and long-term, Korea's ports will vie together with most major ports in the East Asian region. A descriptive investigation shows that Korea's developing tasks in port logistics must be considered in the context of the direction for developing port policies, the necessity of expanding port facilities in the capital region, securing the sufficient traffic volume through the establishment of the hinterland linking system and its positive utilization, and reforming the direction for developing the global logistics through increased port competitiveness. In the short- and medium-term, Korea must use the opportunity factor of 'Growth and open door policy of China' as a geoeconomic advantage and to utilize Korea's ports as a gate to Chinese foreign trade. With the rise of China's economy, China also plays a significant role in both port and airport markets. Hence, the linking system between the two must be established to meet the expanding traffic volume, especially in the capital area. Moreover, it is necessary for Korea to secure port logistics through the establishment of the hinterland linking system and its positive utilization. The great accomplishment of this paper is to present strategies to increase Korea's port competitiveness in the rapidly changing environments of world logistics with the focus on both the oldest military strategic treatise and the newest empirical method in social science. In order to reinforce this study, it needs further compensative research because the evaluation structure could be subdivided with more extensive and precise criteria.

Recently, Free Trade Area generally moves toward a complex and total zone carrying out the logistics and production function simultaneously. Nevertheless, Free Trade Area of Gwangyang Bay Area performs a traditional logistics function only without a introduction of production function. Therefore, the purpose of this research is to suggest alternatives for strengthening the function of Free Trade Area of Gwangynag port. The main findings of this research is summarized as followings. First, a complex and total Free Trade Area through enhancing a production function is to be established. Second, for an efficient management & operation of Free Trade Area, a cooperative system establishment between Free Trade Areas and a single operation system is necessary.

This paper analyses the industrial structure and economic effects of wide-regional zones port logistic industry. The analysis on regional economic impacts is conducted in two ways, among which one is the analysis on the effects of final demand of the industry on regional economy and the other is the analysis on the effects of the industry's production activity with using input-output analysis. Main results of this study are as follows: first, wide-regional zones port logistic industry has lower value-added rate relative to other industries. Busan-Ulsan regional zone has relatively higher value-added rate than other regional zones. Second, the economic effects of final demand and production activity of the industry are found to be the largest in Jeolla regional zone and the lowest in Sudo regional zone.

This study focuses on analyzing the economic effects and probes the necessity of establishing a customs free zone at the Port of Busan. It first considers the economic effects of establishing a customs free zone at the Port of Busan, then suggests policy prescriptions for introducing and operating the free zone system and improving the logistics functions of the Port. The timeline of this study is focused on 2007, when all of Busan Port will operate as a customs free zone and the first stage of the New Busan Port and distribution parks will be built and opened for operation. The regression analysis, which was conducted using the inter-industry relations table(input-output table data), provided a quantitative prediction on the effects of making Busan Port into a customs free zone. Regarding the impact of a free zone system on the domestic and regional economy, this research found that the impact of a customs free zone on domestic industries and the regional economy once the customs free zone is established throughout all of Busan Port would be highly positive. The positive economic effects on the domestic and Busan regional economy might be further strengthened if the value-added logistics function of Busan Port could be supplemented by effective linking to the hinterlands.

As competition in domestic and overseas ports intensify, new and small domestic ports are realizing certain limitations to independently secure competitiveness. This study collected data over 60 months with five modifications for container and general cargo volume around Gyeongin Port. Short-period (12 months) cargo volume was forecasted, which revealed the need for a middle-to-long-term development plan. First, the hinterland logistics complex of Gyeongin Port is expected to contribute to the coastal maritime facility through the quasi-public system for fishery product transportation and passenger services. It proposes to achieve this by opening channels to and from China for precision machinery, home network systems, LEDs, and machine industry items. second, specializing the ultra-light cargo transport route, and connecting the coastal island areas of the 5 West Sea Islands to Ara Waterway (Integrated Fishery Product Center of the 5 West Sea Islands). Third, on the basis of organic cooperation of government? local government ? port, the incentive and pre-circular support system would be required, and lastly, it shall carry out the adjustment of functions in nearby ports and specialization strategy simultaneously through the integrated operation of the ports in the capital areas.

항만구조물의 방파제 또는 방파호안의 마루높이는 배후지역의 활용도에 따라 내습파의 월파로 인한 전달파 또는 월파량에 의해 결정되기 때문에 월파량산정은 항만구조물을 설계함에 있어서 주요한 설계인자이다. 그동안 국내에서는 항만구조물 설계시 주로 외국의 기준이나 기법을 활용하고 있는 실정이다. 국내 항만설계기준에서는 Goda도표를 이용하여 직립제 및 방파호안에 대한 월파량 산정방법을 제시하고 있으나, 도표축이 log로 되어 있어 내삽 또는 외삽시 사용자에 따라 월파량 차이가 발생할 수 있다. 국내의 해역특성 및 최근 설계동향을 반영한 월파량 산정식의 개발이 필요하고, 동일조건에 대한 동일한 월파량 산정결과가 도출될 수 있어야 한다. 최근의 대표 연구성과인 EurOtop(2007)과 같이 지수함수의 형태로 월파량 산정식을 제시하고자 한다. 경사식구조물의 평균월파량 산정식 도출을 위해 적용한 구조물 위치에서의 수심(d_t)은 0.40m, 0.55m, 0.70m 이다. 적용수심을 서로 다르게 한 것은 기존의 대부분의 연구에서 적용하지 않았던 구조물 위치에서의 쇄파조건을 고려하기 위한 것이다. 실험파는 Bretschneider-Mitsuyasu 주파수 스펙트럼을 사용한 불규칙파를 적용하였다. 본 연구에서는 주 피복재로 TTP를 대상으로 하였고, 주기 및 파고를 다양한 조건에서 수리실험을 수행하였다. 본 연구의 실험결과는 월파량 계측을 통해 분석된 평균 월파량을 적절한 산정식으로 나타내기 위해 EurOtop(2007)의 기존 월파량 산정식 형태에 대입하여 비교하여 분석하였다. 따라서, 본 논문은 월파량 산정식 제시를 통해 보다 합리적인 항만구조물의 마루높이 산정이 가능하게 하고, 또한 월파량 산정과 관련된 실험자료 구축을 통해 신뢰성해석 자료 및 수치모형의 검증 자료로 활용될 수 있을 것으로 판단된다.

The waterfront has distinct climate characteristics different from urban or inland area. These may create not only the rise of energy and maintenance costs for facilities located at waterfront areas, but also the negative effects on the climate of the nearby inland area, unless these are treated with particular care. For the present study, the climate characteristics of waterfront were examined with climate data of 10 observation points carefully selected in Busan area. Each weather observation point was classified into either waterfront area of inland area, based on the distance from the coastal line. Special considerations were given to the climate data gathered at the Dae-Yeon weather station because it shows the climate characteristics similar to those of inland area, although it is located very near the waterfront area. Results indicates that this peculiar climate condition attributes, at least in part, to the reclamation of frontal coastal area.
