해저터널은 태풍, 폭우 등과 같은 악천후에도 안정적으로 자국내 도서지역 및 인접국가간 교통 및 물류수송체계 운용을 가능하게 하는 주요 사회기반시설로서 활용되어왔다. 이러한 해저터널 프로젝트를 안전하고 경제적으로 수행하기 위해서는 해저터널의 공학적 특성을 정확하게 이해하는 것이 매우 중요하다. 이에 해저터널의 지반조사를 중심으로 전반적으로 언급하였다. 해저터널은 육상터널과는 달리 조사, 설계 및 시공단계에 있어 많은 불확실성과 위험성을 가지고 있으므로, 프로젝트의 특성에 맞는 정밀하고 정확한 조사는 해저터널의 성공여부를 좌우할 수 있다. 따라서 계획단계에서 철저한 문헌조사 연구 및 해저지형, 지질구조 등에 대한 이해를 기반으로 해저지반 조사계획을 수립 및 수행하여야 한다. 또한 해저터널의 특성상 완벽한 지반조사는 불가능하므로 광범위한 조사에도 불구하고 사전에 예상치 못한 불량한 지반조건을 마주칠 가능성이 크므로, 불확실성과 위험성을 염두에 두고 설계 및 시공에 임하여야 한다.

The land transport industry is more important than the air transport or shipping industry. Land transport has the largest number of business and employees, and the fourth industrial revolution technology has recently infiltrated the most rapidly. In this paper, we examine the status, future prospects, and implications of the land transport industry in Korea for the past 7 years based on the statistical database and related literature. We survey the scope and characteristics of the freight truck or rail transport industry, government policies, and recent logistics industry trends. From the results of these current and forecast statistical surveys, we propose a way forward for the domestic transport business.

Fierce competition to attract the increasing container cargoes of north China in competitive ports has make port marketing to be desperate necessity. In this situation, port marketing of Incheon container ports is requisite conditions to leap one step. Therefore, this study aims to propose core factors for marketing strategy by the feasible marketing analysis. The major shows as follows. Incheon is required to adjust port tariff and handling cost by incentive policy, enhance service coming alongside the berth, increase efficiency of port handling service and inland transportation system.

Road transportation accounts for the largest share of cargo transport in Korea. Inland transportation is not only the beginning and completion point of container transportation, but it is also very complex and has many workers. The main job of container drivers, who play a key role in inland logistics, is to transport containers from ports and terminals to destinations. However, in addition to the main role, various container management obligations, such as cleaning containers and managing damaged containers during the transportation process, are implicitly transferred to container drivers. However, little research has been conducted on this issue. This study identified the working environment of container drivers and empirically analyzed the current status of container management responsibilities by drivers. Furthermore, it analyzed whether there was a difference in the degree of container management requirements by shipping company, terminal, and shipper. Differences in requirements for region(Busan, Kwangyang, Pohang) were analyzed, and improvement measures for the problem of transferring container management were also presented.

Recently, with the development of digital technology, new research cases which applied new technology were increased. Also, the related equipment and services are being developed in the industry. Before new equipment is developed and released, it must go through a verification process. In the maritime industry, equipment is verified through simulation tests or environmental tests on land. However, if only the test on land is conducted, verification data in the actual operating environment might be insufficient. In this paper, considerations are described in the development of an onboard demonstration scenario for verification in the operating environment.

This paper is for the hull form development of high-speed passenger ship in the Yellow Sea. To carry out hull form development in Yellow Sea, a catamaran which is designed for high-speed as well as comfortable passenger vessel up to now is selected and investigated. For this, environments of the Yellow Sea such as tide, water depth and so on are considered as important factor. The economical efficiency of the designed ship is considered too. In order to estimate the resistance characteristics of the designed hull form, numerical simulations and model test are performed.

In case of EU and USA, a short sea shipping and coastal shipping which are safer and environmentally better than road transportation are used widely. But a share of freight transport by a coastal transportation is extremely poor in South Korea. In this paper, we propose a Mokpo-Jeju intermodal transportation based on logistics analysis results. Firstly, we investigate a freight and passenger of a Mokpo-Jeju shipping route. And secondly, the intermodal transportations such as sea-train, sea-road, RORO ship system are investigated. Finally, we propose a coastal transportation system utilizing RORO ship system for Mokpo-Jeju shipping route and identify a technical feasibility of a coastal transportation system.

Recently, a logistics between south and north Korea is rising rapidly by increasing of economical exchange between two Korea and growth of Gaeseoung Industrial Complex. Considering this trend of economic cooperation between two Korea, in addition to a land transportation route it is necessary to secure various logistics and transportation route. A barge transport system which has merits such as a little initial investment and convenience of harbor loading/unloading has been also used to transport freight widely in the EU and USA. In this paper, firstly, a social and economical feasibility study is performed about a shipping route which is using barge transportation system between Incheon and Gaesung. And also we propose several candidate shipping route and investigate a technical feasibility on a realistic possibility of shipping service by some investigation activities. Finally, the optimized shipping route and barge transportation system are proposed in this paper.
