겨울철에 동아시아는 시베리아 대륙으로부터 부는 북서계절풍의 영향을 크게 받는다. 지속성이 강한 계절풍은 선박의 안전운항과 기상재해에 큰 영향을 미친다. 이 연구에서는 30년간(1992-2021년)의 장기간의 데이터를 이용하여 동아시아에 위치해 있는 우리나라와 일본에서의 겨울철 계절풍의 변화를 분석하였다. 분석한 결과는 다음과 같다. 우리나라 서해안에 위치한 군산에서의 풍속은 시간의 흐름과 함께 약해지는 경향을 보이나, 인천에서는 큰 변화가 보이지 않는다. 우리나라 제주도에 위치한 고산은 다른 두 지역보다 월등히 강한 풍속을 보이나, 이 지역 또한 시간의 흐름과 함께 풍속이 약해지고 있음을 확인하였다. 인천, 군산 및 고산 중에서 풍속이 가장 강한 곳은 고산이고, 그 다음은 인천, 군산의 순이다. 일본의 아키타, 와지마, 하마다의 겨울철 풍속은 세 지역 모두 점진적으로 약해지고 있으나, 2000년에 세 곳 모두 풍속이 급격히 강해진 특징을 보였으며 2005-2007년에는 풍속이 다시 약해졌다. 풍속이 가장 강한 곳은 아키타이며, 그 다음으로는 하마다, 와지마 순이다. 우리나라와 일본을 비교하였을 때, 고산을 제외하고는 일본이 우리나라보다 평균적으로 풍속이 더 강한 양상을 띠고 있어, 서해보다 동해에서 계절풍이 더 강하게 불고 있음을 확인하였다.

When comparing the port management type between the both countries, there are some differences at some aspects. And also Korea is to move forward a hub port and logistics center in Northeast Asia while Japan is to pursue providing the port logistics service necessary for the Japanese economy. Major findings and implications are as follows. First, Port authority system should be extended to Gwangyang and Pyeongtaek port step by step. Second, any port which did not introducing a port authority system should enhance cooperating with its own local administration. Third, a port marketing strategy must be established and implemented by a port authority.

The purpose of this paper is to show the empirical measurement way for predicting the seaport efficiency by using SBM with Wilcoxson signed-rank test under CRS(constant returns to scale) condition for 20 Korean ports during 1994-2003 for 2 inputs(birthing capacity, cargo handling capacity) and 3 outputs(Export and Import Quantity, Number of Ship Calls, Port Revenue). The main empirical results of this paper are as follows. First, forecasting data have well reflected the real data according to the Wilcoxon signed rank test, because p values have exceeded the 0.05 significance level. Second, SBM has shown the effectiveness for predicting the ports efficiency even though the predicting powers are different according to the levels of p values. The policy implication to the Korean seaports and planner is that Korean seaports should introduce the new methods like SBM method with Wilcoxon signed rank test for predicting the port performance and enhancing the efficiency.

Today, because the international community recognized happing of environmental crisis on the world the international environmental agreements and advanced country's environmental regulations are very tight. Especially, port cities are posed strong threats to the environment due to receiving high pollution from ships and cargo vehicle emissions. So many advanced country (ex. United States, Japan, EU) implement Natural-friendly Port Policy and Program. Environmental-Regulations become more stringent in the future, management of low carbon dioxide emissions brings the competitiveness.(중략)

This study mainly investigates the port SOC's impact on trade volume. In order to investigate the relationships between port SOC and trade volume, we did the empirical analysis using panel data regression and fixed effects model. The total period of 97 years and 1,082 ports' information were applied to panel data and regression model. According to the results, the coefficients of development of container berth, development of bulk berth, maintenance of port, the jetty facilities like breakwater have positive(+) impact on the dependent variable, the trade volume. Especially, the jetty facilities show a strongly positive impact on trade volume. On the other hand, the development of new port and navigation facilities like lighthouse have a negative(-) impact. In examining Hausman test and LR test, the fixed effect model is statistically more appropriate than the random effect model for this study.

With the change of global production network, the establishment of new strategy in gwangyang port is required. Especially, the trade pattern has been concentrated to Northeast Asia region according to economic growth of the Asia including China, Japan, and Korea. Hence, Gwangyang port that have price and service competition have to meet of the need of Northeast port alliance and to compete against other countries in variable trade environment. Therefore, the objective of this study is to propose the port alliance strategy in order to promote the growth of Gwangyang port. For the purpose of the Logistics business model in Gwangyang port, we provided the direction of the Northeast port alliance and candidate ports in China and Japan.

Opening and regional economic integration are characteristic of global economic trends that have been made since the 1990s. Accordingly, all economic blocs of the world are largely reorganized into three poles, European Economic Bloc, American Economic Bloc and Northeast Asian Economic Block which are respectively led by EU, the United States and the rapidly emerging economic power, China. Considering this direction of global economy, the current status of Northeast Asia, China's unprecedentedly enormous port development project and Japan's introduction of an epoch-making port policy towards the restoration of its port competitiveness, Korea is urgently need to take its own initiatives and positive actions that can cope with the above situations. The purpose of this study is to propose ways of strategic cooperation for Korea-Japan joint development. For the purpose, this researcher provides the concept and preconditions of hub-port, investigates hub-port development strategies of rival companies in Northeast Asia and discusses the potential of the development of the Korea-Japan Strait Economic Zone which is located between Busan port and Japan's Honshu(Simonoseki port) and Kyushu(Kitakyushu port).

The pilotage tariff system in port operations has received little attention in the academic literature. While studies addressing legal issues-such those concerning liability, marine accidents, and compensation for accidents-and institutional aspects have been prevalent, scant research has been conducted in the form of comparative analysis of pilotage tariff systems and current levels of pilotage charges in major ports. The purpose of this research is to investigate the rate structure of pilotage tariffs of major ports. Specifically, this study explores the current level of pilotage price and regulations by comparing the pilotage systems of six major hub ports in the world: Busan, Kobe, Hong Kong, Los Angeles, Singapore and Rotterdam. Results show that Busan Port's pilotage tariff system ranks low (5th) among these six ports. Another finding is that the simplification of Korea's pilotage tariff system will yield productivity and efficiency improvements in this area.

우리나라에서는 1995년 5월 서해권 DGPS 보정정보 전송 서비스를 시작으로 NDGPS 기준국망 구축을 완료하고, 선박의 안전한 항행을 위해 실시간 DGPS 보정정보를 국내 연안과 도서지역에 송신하고 있다. 본 논문에서는 NDGPS와 유사한 보정정보 서비스로서 우리나라에서도 수신이 가능한 일본의 위성기반 보정위성항법체계인 MSAS와 현재 우리나라에서 VHF 대역으로 서비스하고 있는 NDGPS 의 성능을 항해장비 이용 관점에서 비교분석한다. 이를 위해 본 논문은 NDGPS 기준국과 이용자 사이의 기저거리를 기준으로 보정정보 도달시간과 수평측위 정확도를 측정한다. 그리고, NDGPS 와 MSAS 간의 성능차이와 항해장비용 보정시스템으로서 MSAS 적용 가능성에 대한 분석결과를 보인다.
