This study estimates the port waiting cost of international trade ports in Korea by an opportunity cost approach. In the next step, we present a method to assess the levels of port services by the average waiting cost of ships derived from the results of the first step. Because the port waiting cost reflects the social cost, it is difficult to use as a service indicator even though it is the decision support information for a particular port facility expansion. The percentages of waiting ships and time also are insufficient indicators to reflect only the quantitative aspects by the time. However, the average waiting cost of ships in this study can be utilized as a service indicator to reflect waiting time and the loss of economic value simultaneously. It is also very useful information for a shipper and a carrier to select a port. Based on the average waiting cost of ships in 2007, it is analyzed in order of lowest service ports sequentially such as Pyeongtaek-Dangjin, Pohang, Donghae, and Samcheonpo. It is different from the sequential order of ports by the port waiting cost such as Pohang, Incheon, Gwangyang, Pyeongtak-Dangjin, and Ulsan. The port waiting cost is to a port authority as a key indicator what the average waiting cost of ships is to a port user as a useful indicator to evaluate the levels of port services.

In order to study geology and sediment characteristics in Danghang Bay area, surface geological survey, SBP (sub-bottom profiler) survey, and sediment analysis were conducted. Danghang Bay area has a closing coast surrounded by land, and surface layer are covered by mud and sandy mud. Sedimentary facies of the surface layer consists of Mm and Mms facies. A SBP seismic survey shows that gas bearing sediments might be spread throughout the sediment layers, so that it seems to be hard to find acoustic basement and gas seeps are easily found throughout the survey lines. The gas trapped in the sediments may be related to the high organic contents of the sediment, and the thick mud layer may restrain the gas from releasing.

The effect of estuarine dams on fish assembladge in Danghang Bay of Goseong, Korea was determined using monthly samples collected by a beam trawl and a cast net at the natural estuaries and damed estuary from September 2011 to August 2012. In the natural estuaries without dam, salinity was relatively high showing a large diurnal change. Estuarine fishes such as striped sandgoby, Acentrogobius pflaumii and yellowfin goby, Acanthogobius flavimanus, were dominantly caught in the sea side water. In the dammed estuary, freshwater species such as pale chub, Zacco platypus and triden goby, Tridentiger brevispinis were dominanlty caught. The dam in the Danghang estuary have significant effects on the fish assemblage through aquatic environmental change such as salinity.

당해 항만의 장기개발방향을 제시하는 항만종합개발계획(Port Master Planning; PMP)은 향후 해당 항만의 확충 정비 개발을 위한 기본계획이나, 계획의 실행단계에서 많은 한계에 봉착하게 된다. 이 연구에서는 전통적인 PMP의 한계점을 분석한 후, 미래의 불확실성에 대응하기 위한 적응계획(adaptive planning) 방법론을 검토하고, 로테르담항만의 적응계획법 적용 사례 소개 및 시사점을 도출하여, 우리나라 항만개발계획의 견실성과 적응성을 제고할 수 있는 방안을 제시하였다.

The increase in the number of ships entering and leaving the port and the creation of various cargo volumes can promote local economy and lead to regional development, attracting businesses, and influx of local residents. The port area of Dangjin consists of the limited cargo and most private docks, making it increasingly weak in meeting the local economic development and the expectations of local residents. Therefore, in order to promote regional development and revitalize the local economy, and to reduce the sense of alienation of local residents, it is necessary to make it easier to access and water to ports through the development of all areas of Eumseompo-gu, and to make active changes in the marine and port logistics environment. As seen through various cases of port development at home and abroad and the redevelopment of the ports at Gohyeon Port in Geoje, Dangjin Port should be able to quickly demonstrate the development of the Dangjin Port area and improve the quality of life for the residents of the metropolitan area. This is the time when the government's drive is highly requested.

As an exploratory research to understand the nature of relationships between harbors and their neighboring communities, this study analyzes how harbors influence their residents' quality of life(QOL). The QOL was measured by 18 indicators reconstructed by reviewing relevant literatures. As a result, both Busan and Incheon were found to have statistically significant influence on many of QOL indicators including general expenditure per capita, number of manufacturing factories per capita, rate of housing supply, number of financial agencies per capita, number of cultural assets per capita, number of schools per capita, number of sick-beds per capita, and the size of welfare expenditure per capita.

중국과 한반도와의 해상교통은 기나긴 역사의 물줄기의 흘러온다. 일찍이 서기 8-9세기 당과 신라간에 있었던 우호적인 린방항해는 역사상 전성기를 이루었다 이글은 중국 한반도와 일본의 상관 고대문헌을 고찰한 기초상에서 청해진(오늘의 한국완도) 장보고(Znang Bao-gao) 대사를 대표로한 신라인들이 당나라에 대한 항해활동 및 그활동이 남겨둔 역사의 자적을 연구함으로서 당시 당과 신라간의 주요한 해상교통선을 논증하였다 본 연구는 아래와 같이 지적하고 있다 1. 장보고는 서기 8-9세기 신라 항해역사상 아주 큰 영향력을 가진 대표인물로서 그는 이시기 동북아시아 항해활동에 역사적 공헌하였다 그가 오늘날 한국완도 및 중국 산동반도 등의 지역에 남긴 유적 들은 중국과 한국 및 전체 한반도 교통연구에 고귀한 문화재로 중시받을 가치를 지닌다. 2. 서기 8-9세기 신라와 당간 해상교통 노선을 쌍방 항해사들이 장기간의 왕래와 합작의 산물이며 이는 구체적으로 북항로 중항로와 남항로등 세갈래 중요 항로로 나누어진다 그가운데: --- 중국 요령 연해로부터 신라에 도달하는 북항로는 역사가 영구한 전통성 항로인데 항해가 안전하지만 항로가 비교적 길다 --- 중국 산동반도로부터 신라에 이르는 중하로는 당시 쌍방 해상 왕래에 매우 중요한 항로로써 장보고 등 신라 항해사들이 중국과 왕래하던 주요항로이다 ---중국 강소와 절강 연해로부터 신라에 이르는 남항로는 기본적으로 중항로가 남쪽으로서의 영신혹은 추동된 것으로서 그 왕래하던 시기는 당나라 이후 중국 송나라 시기인데 서기 10세기 이후이다.

This paper aims to identify the problems of incentives and find a solution to them by empirically analyzing the port incentives and the development of cargo volume. The current method of paying performance incentives and cargo-increase incentives makes it is possible for shipping companies to get the maximum incentives just by regulating cargo volumes without increasing them. Since the processing volume of transshipment cargo of the Busan port is over the volume eligible for the maximum incentive determined by the tie-up of shipping companies, the transshipment cargo can decrease. The incentive of the Busan port based on the cargo record and increase does not affect the increase of transshipment cargo, only to suffer a loss, and thus a new incentive system is needed that does not allow shipping companies to regulate cargo volumes. Based on the result of this study, We have to apply the even-handed incentive rule which pays the incentive for the cargo volume of the pertinent year with the unit price per 1 TEU to avoid the chicken game among the ports.
