최근 들어, 현대사회는 예측이 불가능한 다양한 위험성들이 존재하여 글로벌 의존도가 높은 항만물류산업의 위험부담이 증가하고 있다. 이에 본 연구에서는 항만산업의 안전성에 영향을 미치는 요인을 알아보기 위해 과거부터 현재까지 국내 항만 안전성에 영향을 미친 이슈들을 시계열적으로 살펴보고자 하였다. 이를 위하여 국내를 대표하는 부산항의 항만 안전성과 관련된 뉴스 기사 텍스트 데이터를 활용하여 LDA 토픽모델링 분석을 진행하여 부산항 항만안전 주요 이슈들의 동향을 살펴보고자 하였다.

This study analyzes the operating conditions of domestic marinas in response to changes in marine leisure trends and demand for recreational boats, and suggests ways to improve services according to the types and functions of marinas. In order to popularize marine leisure and to foster coastal and marine tourism industry, the 'Act on the Development, Management, etc. of Marinas' was enacted in 2010 and 'The 1st Marina Basic Plan' was established, and more than 34 marinas are operated nationwide. In order for domestic marinas to be used as an infrastructure for marine leisure activities, measures for enhancing service functions should be prepared in accordance with the size and characteristics of marinas. It is also necessary to improve facilities for marine leisure management and tourist convenience.

기후변화협약에 대비하고 녹색성장 재원을 마련하기 위해 탄소세 도입이 적극 검토되고 있다. 여러 선진국에서는 탄소세가 도입이 되고 있으며, 일본은 2011년도 2013년도에 탄소세 도입 및 실시가 예정되어있다. 이에 선진국들의 탄소세 도입 및 도입예정 사례를 분석하고, 우리나라의 에너지세제의 현황을 검토하여 탄소세 도입 형태 및 적정 수준에 대하여 검토하여 국내에 탄소세가 도입되었을 때 항만에 미칠 수 있는 영향을 예측하고, 탄소세 도입에 따른 국내 항만경쟁력 강화 방안에 대하여 알아본다.

소극적이었던 환경에 대한 관심이 1992년 리오데 자네이로에서 개최된 유엔환경개발회의 (UNCED)에서 유엔기후변화협약(UNFCCC)으로 채택되고, 이후 1997년 교토의정서에 의해 선진국들은 의무적으로 자국의 온실가스를 감소해 오고 있다. 교토의정서 채택 당시 우리나라는 개도국으로 분류되어 온실가스 감축의무를 면제받았으나 OECD회원국이면서 대량 배출하는 우리나라는 교토의정서 1차 이행기간 (2008~2012)이 끝나는 포스트 교토의정서부터는 감축의무가 부과될 가능성이 높다. 이에 본 논문에서는 포스트 교토의정서에 따라 항만분야에서 야기 될 수 있는 온실가스 배출 구조를 항만하역 활동에 따라 살펴보고 외국 선진 항만의 사례를 통해 국내 항만이 친환경 녹색 항만으로 거듭 날 수 있는 방안을 제시하고자 한다.

Busan port, which had ranked at 3rd busiest port following Singapore and Hong Kong in 2002, has been nudged out of 5th place. Growth of China ports threatens Korea ports to be a hub port in Far East Asia. Therefore, Korea ports are needed to establish competitive strategies to overcome a crisis of local ports. In this paper, the question, 'Who is my competitor?' is examined There is a different aspect between this work and many studies that has been done before, because the fore studies focused on the competitive factors or port efficiencies. Above all, the meaning of competition among ports has been summarized through existing literatures. Next. the competition structure among ports is researched, based 0/1 import-export traffic of five local ports including Busan.

There has been abundant empirical research undertaken on the technical efficiency of Korean ports. Most studies have focused on the use of parametric and non-parametric techniques to analyse overall technical efficiency. This paper utilizes data for the period 2000-07 to offer a heterogeneous perspective on the overall efficiency of Korean ports. The framework assumes that ports use one input to produce one output; the output and input include port export(import) and regional export(import). This paper also employs panel analysis and heteroscedastic Tobit model to show the effect of the explanatory variables on the port efficiencies. The panel analysis shows that the regional export/total export has negative effect on the export efficiency while the regional import/total import has not any relations with the import efficiency. The heteroskedastic Tobit model shows that both regional export ratio and regional import ratio have negative effects on the efficiency while the gross regional domestic product has not any significant relations with the import efficiency.

The purpose of this paper is to show the empirical measurement way for predicting the seaport efficiency by using Super SBM(Slack-based Measure) with Wilcoxson signed-rank test under CRS(constant returns to scale) condition for 20 Korean ports during 11 years(1997-2007) for 3 inputs(port investment amount, birthing capacity, and cargo handling capacity) and 5 outputs(Export and Import Quantity, Number of Ship Calls, Port Revenue, Customer Satisfaction Point for Port Service and Container Cargo Throughput). The main empirical results of this paper are as follows. First, Super SBM model has well reflected the real data according to the Wilcoxon signed rank test, because p values have exceeded the significance level. Second,Super-SBM has shown about 87% of predicting ratio for the ports efficiency and the optimal size of investment in domestic seaport. The policy implication to the Korean seaports and planner is that Korean seaports should introduce the new methods like Super-SBM method with Wilcoxon signed rank test for predicting the efficiency of port performance and the optimal size of investment as indicated by Panayides et al.(2009, pp.203-204).

This study predicted Port trade volume by considering Korea's export to China and import Com China separately using ARIMA model (Multiplicative Seasonal ARIMA Model). We predicted monthly Port trade volumes for 27 months from October 2008 to December 2010 using monthly data from September 2008 to January 2001 using monthly data. As a result of prediction, we found that the export volume decreased in January, February, August and September while the import volume decreased in February, March, August and September. As the decrease period was clearly differentiated, it was possible to predict export and import volumes. Therefore, it is believed that the results of this study will generate useful basic data for policy makers or those working for export and import enterprises when they set up policies and management plans. And to improve competitive power of Port trade, this study suggests privatization of Port, improvement of information capability, improvement of competitive power of Port management companies, support for Port distribution companies, plans for active encouragement of transshipment, and management of added value creation policy.

The purpose of this paper is to show the clustering trend and the comparison of empirical results and is to choose the clustering ports for 3 Korean ports(Busan, Incheon and Gwangyang Ports) by using the bootstrapped DEA(Data Envelopment Analysis) and game Cross-efficiency models for 38 Asian ports during the period 2003-2013 with 4 input variables(birth length, depth, total area, and number of cranes) and 1 output variable(container TEU). The main empirical results of this paper are as follows. First, bootstrapped DEA efficiency of SW and LT is 0.7660, 0.7341 respectively. Clustering results of the bootstrapped DEA analysis show that 3 Korean ports [ Busan (6.46%), Incheon (3.92%), and Gwangyang (2.78%)] can increase the efficiency in the SW model, but the LT model shows clustering values of -1.86%, -0.124%, and 2.11% for Busan, Gwangyang, and Incheon respectively. Second, the game cross-efficiency model suggests that Korean ports should be clustered with Hong Kong, Shanghi, Guangzhou, Ningbo, Port Klang, Singapore, Kaosiung, Keelong, and Bangkok ports. This clustering enhances the efficiency of Gwangyang by 0.131%, and decreases that of Busan by-1.08%, and that of Incheon by -0.009%. Third, the efficiency ranking comparison between the two models using the Wilcoxon Signed-rank Test was matched with the average level of SW (72.83 %) and LT (68.91%). The policy implication of this paper is that Korean port policy planners should introduce the bootstrapped DEA, and game cross-efficiency models when clustering is needed among Asian ports for enhancing the efficiency of inputs and outputs. Also, the results of SWOT(Strength, Weakness, Opportunity, and Threat) analysis among the clustering ports should be considered.
