This study investigates the initiatives of Gangwon sea routes based on precedent studies on the North Pole route to suggest a multi-modal buildup of transport logistics network of Gangwon harbors for the strengthening of logistics efficiency in the Korean Peninsula. The findings were: First, the government should expand railway infrastructure in Gangwon. Second, harbors in Gangwon should each have one speciality to strengthen connection with other harbors by using railway oriented background transportation network. Third, the government should develop industries of EFEZ(East coast Free Economic Zone) in the East Sea Coast in Gangwon to connect resources from the North Pole Sea. Fourth, the government should invite the base of Araon Ho's polar research vessel to play the role of the North Pole Sea route in the near future. Fifth, the government should strengthen the role of the Samcheock LNG base under construction. SIxth, environment-friendly transportation technology should be introduced to reduce carbon emission as much as possible. Lastly, an optimum North Pole logistics route should be developed to connect the Metropolitan area(Metropolitan Economic Zone), Gangwon roads and railway, Gangwon habor, Trans-Siberian Railway and thw North Pole route, and Europe, to strengthen national foreign trade power in the near future.

Interests in clean fuels have been soaring because of environmental problems such as air pollution and global warming. Unlike fossil fuels, hydrogen obtains public attention as a eco-friendly energy source because it releases only water when burned. Various policy efforts have been made to establish a hydrogen based transportation network. The station that supplies hydrogen to hydrogen-powered trucks is essential for building the hydrogen based logistics system. Thus, determining the optimal location of refueling stations is an important topic in the network. Although previous studies have mostly applied optimization based methodologies, this paper adopts machine learning to review spatial attributes of candidate locations in selecting the optimal position of the refueling stations. Machine learning shows outstanding performance in various fields. However, it has not yet applied to an optimal location selection problem of hydrogen refueling stations. Therefore, several machine learning models are applied and compared in performance by setting variables relevant to the location of highway rest areas and random points on a highway. The results show that Random Forest model is superior in terms of F1-score. We believe that this work can be a starting point to utilize machine learning based methods as the preliminary review for the optimal sites of the stations before the optimization applies.

In this study, SNA analysis was conducted to examine changes in passenger movements in domestic coastal shipping. The validity of derivation of centrality rankings was enhanced by using the connection centrality that reflected weights, which had not been applied in previous research. The results of the connection centrality analysis indicated that the network composition ratio of the South Sea region was high, and the results of analysis of betweenness centrality indicated that ports belonging to the South Sea region recorded high ranks. Jeju Island, which acts as a gateway to the West Sea and the South Sea, Mokpo, which acts as a gateway between the land and islands, those ports that are geographically close to the land, and those ports that are smoothly connected to small ports, were shown to have betweenness centrality. Meanwhile, in the results of analysis of eigenvector centrality, not only ports in the South Sea region but also many ports in the West Sea region were included in the high ranked ones. Using these results, the port authority can identify major ports in domestic coastal shipping, determine the priorities support, identify the current situation of the port connection relations, and establish strategies for management of key development areas. As future studies, studies in the aspect of economy that separate general passengers and island passengers and utilize data such as fares, distances, and time are necessary.
