In this paper, we tackled the marine leisure business of the archipelago at the southwest sea area which has the natural advantage for marine leisure. We also discuss how to adapt the yacht business on the above area. At first, we will introduce the predominant case on the marine leisure business of the overseas. Next we will analyze the current situation of the domestic marine leisure and draw up a plan to solve its problem. Finally we apply an environment friendly marina establishment to the archipelago at the southwest sea area and evaluate its validity.

In this study, the index for operation evaluation index for safety management system that can be facilitated as the assessment tool for system operation monitoring and operation outcome and the safety management system of shipping companies has been developed. By using this index, this study may provide the instruction or consultation for frequent facilitation by comprehensively recording the required knowledge for each operation stage for the companies that prepares the introduction of the safety management system and companies that already introduced the system to maintain and develop the system. In addition, when working on internal audit and assessing the system operation outcome, it may be facilitated as the assessment tool to contribute in continuous improvement and development. This index is consisted of 11 large categories, 35 items of medium categories and 447 small categories.

The furrow calculation and traffic measurement of sailing ship using computer vision are useful methods to prevent maritime accident by predicting the possibility of an accident occurrence in advance. In this paper, sailing ships are recognized using image erosion, differential operator and minimax value, which can be verified directly because the calculated coordinates are displayed on electronic navigation chart. The developed algorithm based on area information of this paper has the advantage which is compared to the conventional radar system focused on point information.

In this paper, we study the fishery detection system for protection of an aquamlture farm. The FDS(fishery detection system) will be recognize a robbing vessel with real time and variance the position of aquaculture farm. We try to develop the F-AIS(Fishery Automatic Identification System) which am be detect approaching object to aquaculture farm and distinguish our fishing boot from thief vessel. The F-AIS with low price and wideband responsibility am be adopt to the FDS, i. e. the identification for a small-sized fishing boots.

This paper presented a robust ship scheduling model using the quadratic programming problem. Given a set of available carriers under control and a set of cargoes to be transported from origin to destination, a robust ship scheduling that can minimize the mean-variance objective function with the required level of profit can be modeled. Computational experiments concerning relevant maritime transportation problems are performed on randomly generated configurations of tanker scheduling in bulk trade. In the first stage, the optimal transportation problem to achieve maximum revenue is solved through the traditional set-packing model that includes all feasible schedules for each carrier. In the second stage, the robust ship scheduling problem is formulated as mentioned in the quadratic programming. Single index model is used to efficiently calculate the variance-covariance matrix of objective function. Significant results are reported to validate that the proposed model can be utilized in the decision problem of ship scheduling after considering robustness and the required level of profit.

Recently, many ships such as fishing boats, cargo ships, high speed ferry boats are visiting Mokpo harbor. In particular, many marine accidents have been occurred at this area due to the narrow channel, a thick fog, the existing of the shallow waters etc. However there is no suitable ships' routeing system which takes account of today's traffic situations in this area. This study aims at the settling of hazardous factors to mitigate the danger to vessels in Mokpo harbor and to secure the safety of maritime environment.

Maritime terrorism at sea is the form of violent interference with shipping. Its global reach and negative impact on sea transportation, safety of navigation and marine environment, as well as the threat it poses to human lives and property, call for effective countermeasures at the international and national level at the same time. First, this paper gives a factual assessment of the phenomenon of maritime terrorism as well as a legal analysis of the international provisions to suppress such forms of violence at sea which is different from piracy. And also this paper attempts to address and identify issues relevant to the existing international regulations such as SUA Convention as the main source of international regulations applicable to acts of terrorism at sea, ISPS Code, PSI, etc. Finally this paper suggests the national countermeasures against maritime terrorism in light of above mentioned the definition, causes, types of maritime terrorism and concerning international regulations.

To improve maritime security and enhance international shipping commerce within US ports in addition to ISPS (International Ship and Port Facility Security Code), the TWIC (Transportation Worker Identification Credential) program is working on the maritime field from the October 15, 2008 in the United States. In this paper, the program is reviewed and investigated in terms of goal, benefit, solution, and related legislation so forth In addition, other maritime security programs including MMD (Merchant Mariner Document), FAST (Free and Secure Trade), SIDA (Security Identification Display Areas). and Air Cargo security program was analyzed and compared in order to obtain relationship and difference with the program in terms of enrollment frequency, list and method of security check, and profile of each program As a result of this paper, the program is mostly to improve maritime security, protect individual privacy, and enhance commerce rather than other programs.

This report represents analysis of the maritime casualty in terms of Bridge Resource Management. We evaluate the attitudes and knowledge of bridge officer regarding human factors issues that have been identified as causal to mishaps in high-risk situations. So to reduce human errors our goal is to establish effective officer resource management (ORM) program which is based on all subjects for cadets in IMO model course. In harmonization with STCW(The International Convention on Standards of training, Certification and Watch-keeping for Seafarers), as the result, the curriculumss in the maritime education institutions is surveyed to improve our education system and then reduce the human errors by mariners at sea.

Interest about Modal Shift is not being decreased, and it is drawing limelight as green logistics which meets low carbon green growth of National development vision. As an effect of Modal Shift, not only reduction in CO2 emission but also reduction in social cost, logistics cost etc. are being discussed. However, until now research about its practical transformation effect has been scanty. In this study, the actual expenses via CO2 emission, social cost, and logistics cost etc. by road transportation and rail transportation of container cargo with Origin/Destination between Busan-Kyeonggi Area were calculated and we propose beneficial effects when transportation mode is transformed from road to rail with Scenario Planning.
