Since ports play a role of gateway to the sea and hinterlands, it is essential to analyse the networks of shipping and inland when evaluating the function and development of a port. The container port of Gwangyang, starting to operate its facilities in 1998, has developed itself as a hub port. Using the data of shipping schedules of Korean ports and the measurement of centrality in sociology, this study analyses the process of world-wide shipping network expansion in Gwangyang and concludes some implications including earlier development of shipping networks due to incentives to shipping companies. Although Gwangyang port also has been expanding its inland network through developing trucking, railway transport, and coastal shipping, it has weakness in inland network as in the cases of interruption in 2004, resumption in 2009 and re-interruption in 2012 at coastal shipping. In 2000s the expansion of shipping and inland networks at the newly built container ports such as Pyungtaek, Ulsan, and Gunsan has enticed the competition among Korean ports at each hinterland. Nevertheless, the operation of Gwangyang container port is considered to affect indirectly the relocation of some manufacturers including Samsung Electronics. Studies on interrelation between development of container port and geographical demography of manufacturers are needed to assess the effects of container port on regional economy.

우리나라는 수출입화물의 99% 이상이 항만을 통해 해외로 운송되고 있는 관계로 해상화물 운송이 국가적으로 매우 중요한 역할을 수행하고 있다. 해상화물은 크게 일반화물(벌크화물)과 컨테이너화물로 구분되는데 컨테이너화물은 갈수록 그 비중이 증가하고 있어 국내 물류망 개선뿐만 아니라 물류비 인하와 관련해 매우 중요한 부분을 차지하고 있다. 따라서 컨테이너화물의 운송에 대한 기초 연구들은 사회경제적으로 매우 중요한 역할을 담당하고 있다. 본 연구에서는 2011년 기준 우리나라 컨테이너화물의 내륙기종점(O/D)에 관한 연구 분석결과를 중심으로 국내 수출입컨테이너의 주요 항만별, 수입 수출별, 내륙시도별 분포 현황을 살펴 본 후 그 시사점을 도출하고자 한다.

몽골은 중국과 러시아에 의해 바다를 접할 수 없는 내륙국가로서, 지정학적의 한계를 가지고 있어 해운산업의 역할이 매우 약한 나라이다. 하지만 해상운송의 중요성과 내륙 복합운송의 증대로 인하여 몽골에서도 해운의 중요성이 부각되고 있다. 이러한 상황에 중요한 것이 해운 인적 자원 양성이라고 판단된다.

우리나라의 '국토 종합 물류 네트워크' 구축에 기존의 항만, 도로, 철도 중심의 물류 체계에, 국토의 삼면이 바다로 둘러싸여 있으므로 주요 항만과 연계하는 국토 내륙은 물류 수송체계와 주요 강(江)이 수로(水路)유역의 광역권 및 주요 도시가 연결되어 있기 때문에 수로를 이용한 물류수송체계와 통합한 종합적인 국토 물류 수송체계에 대한 연구가 필요하다. 이 연구에서는 파워심시뮬레이션 기법을 이용하여 우리나라의 수로운송을 통한 국토종합물류체계망 구성방향을 도출하였다.

This study examined economic ripple effect of marine transport and port industry using Input-Output Tables. The results of the study are summarized as follows: first, in 2005 production inducement coefficients of harbour facilities was the highest(1.958), followed by coast and inland water transportation(1.857), load and unload(1.842), other transportation services(1.768), storage and warehouse(1.676), water transportation assistant services(1.422), and outport transportation (1.283). Second, value added inducement coefficient of water transportation assistant services was the highest(0.924), followed by load and unload, storage and warehouse(0.902), other transportation services(0.885), harbor facilities(0.832), coast and inland water transportation (0.752), and outport transportation(0.258). Third, import inducement coefficient of outport transportation was the highest(0.742), followed by coast and inland water transportation, harbor facilities, other transportation services, load and unload, storage and warehouse, and water transportation assistance services. Fourth, indexes of the sensitivity of dispersion of other transportation services and load and unload were 1.125 and 0.882 respectively while those of harbor facilities and outport transportation were 0.514. Indexes of power of dispersion of harbor facilities, coast and inland water transportation, load and unload, and other transportation services were the highest, respectively 1.006, 0.954, 0.946, and 0.908 while that of outport transportation was low, 0.659.

Inland transport becomes more and more important in connecting ports with inland. Therefore, studying on cargo flow from ports to regions has been active in progress by many researchers. However current statistical data of freight flow from origin locations to destination locations does not reflect the exact characteristics of freight flow. Also, they also do not reflect the characteristics of multimodal transport system in which cargos go through intermediate locations such as logistics center or inland container depot. In growing up the emergent need of rebuilding statistical data for freight flow from origin locations to destination locations, this paper will propose a freight flow model with logistics center and it will be verified by genetic algorithm through the simulation scenarios.

몽골 매우 풍부한 지하자원을 가지고 있지만 물류 및 운송시설 미비로 인하여 발전하는데 한계가 존재한다. 물류 개선을 통한 경제발전을 위해서는 해운의 역할이 필요하다. 내륙국가로써 해상운송을 추진하기 위해서 무엇보다 몽골 정부의 강력한 의지가 중요할 것이다. 현제 몽골은 광산 분야가 국가경제의 원동력이므로 이를 잘 활용하여 경제성장을 이끌어 내야 할 의무가 있다. 본 연구에서는몽골 물류 발전을 위해서 해상운송의 현황, 문제점, 방향 분석을 하였다.

동절기 혹한으로 인해 내륙 수로가 결빙될 경우 수로 운항이 상당 기간 불가능해짐에 따라 경제적 손실이 발생하게 된다. 연안 해운이 주로 발달한 우리나라의 경우 동절기 결빙에 따른 선박 운항 장애에 관한 사례가 많지 않지만, 내륙 수로 운항의 비중이 높고 혹한기가 긴 북유럽과 미국 북부지역에서는 수로 결빙의 메카니즘 및 대처 방안에 대한 연구가 많이 이루어져 왔다. 본 논문에서는 지금까지 밝혀진 주요한 수로 결빙 메카니즘 및 해결 방안에 대하여 소개하였다.

Many countries are developing transportation technologies aimed at reducing environmental pollution and the environmental burden. For example, environmentally friendly transportation routes and methods are being used to improve inland waterways in Europe. Against this backdrop, a case study was conducted on special cargo (weight cargo, earth and sand, etc.) on Korea's Gyeong-In Ara Waterway, an inland waterway connecting the Han River and the West Sea, serving a distribution function. The results of the analysis showed that coastal shipping could be promoted using the waterway, including a positive synergy among environmental, economic, and social aspects. That is, by shifting from overland transportation to marine transportation, it is possible to reduce environmental pollution, ease traffic congestion, decrease traffic accidents, and shorten the licensing period for the weight cargo demand of the northern area of the Han River. In this respect, the Gyeong-in Ara Waterway could become an environmentally friendly transportation route, promoting coastal shipping in Korea. However, for this to occur, support systems such as subsidies for marine transportation and using the inland waterway are required, as happens in the EU. Furthermore, existing policies to promote coastal shipping should be improved and applied more broadly.

This study assesses the appropriate amounts and applicable ranges of travel time values for freight transport modes in Korea. The findings suggest that it is possible to determine appropriate sizes and applicable ranges of travel time values of goods set for road transport mode (i.e. truck), whereas those for railway, inland waterway, marine, and air transport modes are not as easily estimated. The adequate travel time value for trucks is 20,000won/vehicle hour, and the application range of travel time value of trucks is 17,000~23,000won/vehicle hour considering other variables. The most adequate estimation method of determining the travel time value for road transport is the wage rate method, whereas the marginal rate of substitution method is more rational for railway, inland waterway, marine, and air transport modes considering the application purpose and characteristics of the goods transported.
