차량화물은 국내 품목별 수출물량의 2위를 차지하는 수출화물로(현재 2007년 상반기), 한미 FTA 이후 수출물량이 점차 더 증가할 것으로 예상되어 그 중요성이 높아지고 있다. 이러한 수출 차량화물을 해상운송하는 Car Carrier업체(차량화물 운송전문 업체)의 효율적인 수출업무 처리를 위해, 실시간으로 변하는 정보를 효과적으로 표현 및 변경이 가능하고, 운송계획에 필요한 관련 정보를 제공받을 수 있는 시스템이 필요하다. 그러나 현재 대부분의 Car Carrier업체는 작업자의 경험에 의존한 수작업으로 운송계획을 수립하는 문제점이 있다. 본 연구에서는 Car Carrier업체의 해상운송계획 수립 시 의사결정을 효율적으로 지원할 수 있도록 사용자 인터페이스를 강화한 RIA(Rich Internet Application)기반의 자동차 해상운송계획시스템을 설계 및 개발하고자 한다.

To design ship channel is one of important factors for planning and developing a port. Bends in channel should be avoided if possible, but the channel should be widened, if channel bend is unavoided, to account widened path of a ship in bend for the safe passage of a ship. In this study, Variable Bumper Area(VBA) model is applied to determine ship channel width in bend and channel-bend geometry. The result of this study shows that the width of a channel in bend may be designed as wide as the width in straight lane provided the angle of deflection is less than 30 degree, should be widened for 60degree deflection based on the length of the largest ship using the channel and the angle of deflection.

To design ship channels is one of important factors for planning and developing a port. Bends in channels should be avoided if possible, but the channel should be widened, if channel bend is unavoidable, considering the swept path of a ship for safe passage. In this study, Variable Bumper Area(VBA) model is applied to determine the channel widths in bends. The result of this study shows that the width of the bend may be designed as nearly same size of that in straight channel in case that the angle of deflection is less than 30 degrees, and that of the bend with 60 degrees deflection should be widened based on the length of the largest ship using the channel and the angle of deflection.

The Korea Maritime Safety Tribunal is an institution that investigates marine accidents in accordance with the maritime safety adjudication procedure when marine accidents occur. It requires its investigators to be capable in specializing in marine accidents, including possessing the following: a level 2 or higher maritime license, experience on boarding, and specialized knowledge on ships. It also requires separate training for technical competency related to maritime accident investigations. However, the current education for marine accident investigators mainly consists of administrative tasks, which is not suitable to improving the investigator's technological competency, making its development urgent. This study aims to design training contents for marine accident investigators to strengthen their technical competence. To this end, we analyzed the contents of current investigator training, and reviewed the relevant laws and regulations, and training contents of investigators in advanced maritime countries and similar transportation institutions in Korea. According to the results, the training contents were designed to focus on strengthening technical competency, and proposed as a five-day course for basic and professional training. Based on the designed training contents, if in-depth research is conducted by sufficiently reflecting the working conditions of marine accident investigators in Korea, it will greatly help in improving the investigators' skills.

The main purpose of this study is to provide an objective evaluation standard for the assessment of marine spatial characteristics via Ulsan floating offshore wind power project using HEA.. Various levels of damage occur in the waters (5,017.6) near the floating offshore wind power terminals in Ulsan, including commercial damage, ecological destruction and reduction in quality of life due to seascape damage. Alternative restoration projects for calculating the economic value of damage were selected including artificial reef projects and estimates based on HEA. For basic households with a 4.5% social discount rate and a 100% maturity index over four years, the damage was approximately 457 hundred million won. The HEA in this study resolves the possible irrationality in the evaluation of marine spatial characteristics, since the value is calculated based on objective and clear DATA. Therefore, the study results are intended to facilitate conflict resolution between stakeholders in the future during the implementation of the marine spatial plan.

Historically, humans settled in waterside areas that provided abundant resources and water resources. Afterwards, as industrialization progressed, the city's waterfront contributed to the development of the city through water resources, transportation, and maritime trade. In response to changes in industrial structure, over the past few decades, the city's waterfront has transitioned from an industrial and port-oriented function to a public space function. And from the perspective of urban regeneration, research and design on sustainable waterfront space development are being promoted around the world. However, areas near waterfronts are geographically vulnerable to the direct impact of natural disasters caused by climate change, such as sea levelrise and floods. Therefore, it is essential to establish a systematic management plan to ensure the safety of citizens and publicness. Since the 1990s, New York City in the United States has been establishing a city-level waterfront space management plan to ensure the public nature, safety, and equity of waterfront spaces. On the other hand, in South Korea, there is a lack of research on city-level waterfront management plans. Accordingly, this study sought to find implications and policy improvement measures for domestic waterfront space planning by examining the development process and major policies of New York City's waterfront comprehensive plan.

The shuttle that currently connects Busan New Port to the logistics companies in the Hinterland has the following companies: first, resources are consumed redundantly as each logistics company has independent transport vehicles. Second, the companies are not taking advantage of geographical merits of clustered complexes because different vehicles are used each time due to irregular schedules. In this respect, this study had the following purposes to realize these solutions: first, heuristic approach was made for operation scheduling and real-time operating rules to configure the best possible dynamic plan. Second, the reduction of consumption of resources with the shuttle and the efficiency were examined through a simulation of pooling and dual cycling applied to logistics companies' shipping plans.
