  • This study is tried to determine the probability rainfall-depth of Seoul, Daegu and Mokpo easily by using a regression line. The correlation between the probability rainfalldepth of each duration from 10-minute to 120-minute and return period is derived so as to become the linear least squares curve fit, and the analytical method that the probability rainfall-depth about the given duration is able to be gotten directory on it is studied. In this research, fair correlation among them is shown, and when the variables are transformed suitably, the application of this method to other points besides three cities are considered to be possible.

  • 항만에는 다양한 조직이 물류 기능을 수행하기 위해 화물관련 데이터베이스를 독 자적으로 보유·운영하고 있다. 선사는 화물선적예약 및 선적 데이터, 컨테이너터미널은 컨 테이너 반 출입 및 q관 데이터, 관세청의 통관시스템(CAMIS)은 통관 및 적하 목록 데이터, 해앙 수산청의 항만운영정보시스템(POST-MIS)은 선박 및 입출항 데이터 등을 가지고 있 다. 이들 데이터는 개별 조직 내에 각 조직의 활동을 원활하게 수행할 수 있도록 구조화 및 코드화 되어 있지만 조직간 연계가 되어 있지 않아 여러 가지 문제점을 야기하고 있다. 따 라서 본 연구에서는 컨테이너 화물을 중심으로 한 항만 물류 유관 조직들이 보유하고 있는 시스템의 문제점을 조명하고 나아가 항만 물류 통합 데이터베이스의 구조 및 역할을 정의하 였으며 새로운 항만물류시스템과 통합데이터베이스 구축을 위한 전략을 제시하였다.

  • '체선'은 입항한 선박이 하역하지 못하고 대기하는 상황을 나타내는 말이며 이는 항만의 비효율성을 초래하고 금전적인 손실을 가져다준다. 따라서 본 논문에서는 기존 관제정보 API를 활용하여 체선율 분석 및 예측 시스템을 제안하고자 한다. 이를 통해 항만 시설 관리자에게는 투자방향성을 제공하고, 선박과 화주에게는 물류효율성을 제공해 줄 것으로 기대된다.

  • Korea and China have maintained sea routes between two nations through the shipping conference which was established in May 1993. Due to this effort, the market of Korea-China car ferry on Yellow sea makes growth year by year. The car ferry business has shown fierce competition because it has huge impacts on regional and national level economy. In this respect, the aim of this research is to analyze the structural analysis for ports of Korea-China car ferry using Shift Effect(SE) method. As a results, passengers and cargo volumes of Incheon port continuously transfer to Pyeontaek and Gunsan port. Moreover, absolute growth rate of Incheon port do not reach the potential growth rate. The competitiveness power of Incheon port has lower position compared to Pyeontaek and Gunsan port. The cargo volumes of ports located on western coast of Korea have increased recently, however, passengers and cargo volumes of Incheon port have shown lower increasing rate compared to average of Korean western coast ports. For Incheon port, high value added cargoes which give large profit on port side, have to be attracted. Moreover, Incheon port has to become a specialized port.

  • The purpose of this paper is to analyze the relationship between the budget allocation of Busan-Gwangyang port and political variables such as general election, presidential election, local election and political regimes. To do this, this study did correlation analyses using budget data of all ports in Korea, Busan, and Gwangyang during 1985-2007. The main results of the correlation analyses are as follow: First, there was a positive correlation between budget of Busan and local election. Also, there was a positive correlation between budget of Gwangyang and presidential election. This results suggest that public choice model and political business cycle model seem to apply to the port development policy. Second, there was no correlation between the regionalism of the political regime and budget of Busan-Gwangyang ports. Third, it can be inferred that the national agenda of the hub strategy can be positively related to the implementation of port development budget. Further studies are needed to analyse the relationship between the political variables and establishment of port plan, decision making about port development and ground-breaking of port construction.

  • Competitiveness of container ports has been traditionally evaluated by capability of individual ports to provide services to customers or their service quality. However, since container ports are connected by container shipping networks to varying degrees, the status of the ports in liner shipping service networks also determines competitiveness of the ports. Sometimes same ports may play different roles in different forms of shipping networks. Shipping network connections that formulate in container ports therefore have more significant impact on their performance than service capabilities they have. This study aims to explore how the shipping and port network has been structured and changed in the past and to examine the network characteristics of ports using Social Network Analysis(SNA). In this SNA study, nodes in the network are the ports-of-call of the liner shipping services and links in the network are connections realized by vessel movements, such that the liner shipping networks determine the port networks. This study, therefore, investigates the liner shipping networks and through its results demonstrates the network characteristics of the ports that are represented by the four centrality indices. This provides port authorities and terminal operating companies with managerial implications to enhance competitiveness from customers' perspectives.

  • As the scope of supply chains expands globally, unpredictable risks continue to arise. The occurrence of these supply chain risks affects port cargo throughput and hinders port operation. In order to examine the impact of global supply chain risks on port container throughput, this study conducted an empirical analysis on the impact of variables such as the Global Supply Chain Pressure Index (GSCPI), Shanghai Container Freight Index (SCFI), Industrial Production Index, and Retail Sales Index on port traffic using the vector autoregressive(VAR) model. As a result of the analysis, the rise in GSCPI causes a short-term decrease in the throughput of Busan Port, but after a certain point, it acts as a factor increasing the throughput and affects it in the form of a wave. In addition, the industrial production index and the retail sales index were found to have no statistically significant effect on the throughput of Busan Port. In the case of SCFI, the effect was almost similar to that of GSCPI. The results of this study reveal how risks affect port cargo throughput in a situation where supply chain risks are gradually increasing, providing many implications for establishing port operation policies for future supply chain risks.
