In the last 5 years, a total of 567 accidents of operating vessels occurred under the influence of alcohol at sea, most of which occurred in fishing boats. Accidents caused by operating vessels under the influence of alcohol at sea are causing human and physical damages. There were 69 accidents caused by operating vessels under the influence of alcohol, leading to five deaths and one missing. The social damage due to operating vessels under the influence of alcohol is also increasing. Under the current law, punishment is given lightly compared to the seriousness of violation. In order to prevent the recurrence of accidents caused by operating vessels under the influence of alcohol, cases in Korea need to be analyzed. Regulations on the crackdown in foreign countries were compared to those in Korea and reviewed. In addition, risks of operating vessels under the influence of alcohol should be provided to ship workers while improving related laws and systems. In addition, efforts should be made to reduce the number of accidents due to operating vessels under the influence of alcohol by strengthening crackdowns on ships at sea so that accidents caused by operating vessels under the influence of alcohol could be prevented in advance in the future.

Collision accidents happen frequently. The majority of ships involved in collisions in the coastal areas of Korea are middle and small size ships. The proportion of collision accidents is only 9% of all types of marine accidents; however, the number of casualties resulting from collisions is 34.4% of all human life damages. Generally, as reported by the people involved in these collisions, the navigation lights of the opponent ships were poor and invisible when the accident happened even though the weather and visibility were good. Furthermore, there are many insistences for poor navigation light conditions of the opponent ship in the bay or harbor. Therefore, it is necessary to analyze the present conditions and safety of navigation lights. Therefore, in this study, we examined the rules and books of navigation lights and compared it to that of other transportation systems, such as aircraft, trains, and road vehicles. Furthermore, we analyzed the current marine traf ic circumstances and ship collision accidents that happened in the past 5 years. Additionally, a questionnaire was prepared to gather the opinion of ship experts and secure the objectivity for improvement methods of navigation lights. Finally, methods to improve the navigation lights on ships were devised.

The purpose of this study was to extract the evaluation factors and assess the relative importance between the factors. For this purpose, the evaluation factors were extracted through literature review and the process of brainstorming with experts, who are related to port security. The evaluation factors were then classified into four higher factors and twelve sub- factors through the use of the AHP method. A survey on the classified factors was conducted by experts composed of public officials, port authority employees and education institutions officials. We also carried out statistical tests to determine the perception gap of weights between the groups. As a result of a relative importance analysis of strength, the security operating system factor was highest, followed by improvement of hardware facilities and increase of security personnel. There was a difference in perception among the groups in policy support, facility support and personnel resources budget support. The results of the analysis show that the strength operating system through the establishment of an integrated monitoring system is a priority. It is necessary to understand the difference of perception between groups and build a systematic cooperation system. The evaluation factors extracted from this study can be used for the measurement of port security efficiency in further work.

해양환경에 관한 정보는 효율적인 연안 해역 관리를 위해 필수적이며, 해양환경요소에 대한 분석을 위해 현장 실측자료뿐 아니라 과거자료, 현재자료, 예측자료 등이 요구된다. 또한 연안환경 관리자뿐 아니라 해상관련 종사자, 어민 등이 해양환경 정보에 빠르게 쉽게 접근할 있는 기반이 마련되어야 한다. 최근에는 물에 관련된 정보를 효율적으로 관리하고 제공해야 하는 필요성이 증가함에 따라 물정보학(Hydroinformatics)이 크게 관심을 받고 있으며, 학술지 발간 및 학술회의 개최 등을 통해 이에 관한 연구가 활발히 진행되고 있으나 연안환경에 대한 연구는 미흡한 실정이다. 체계적인 연안환경 분석을 위해서는 방대한 시공간 자료가 필요할 것으로 예상되며, 지속적인 모니터링을 위한 통합시스템이 요구되므로 다양한 관측방법 적용될 필요가 있다. 본 연구에서는 인공위성을 활용하여 연안환경 변화를 모니터링 할 수 있는 방안을 제안하기 위해 국외의 연구사례들을 분석하고, 우리나라 연안환경에 적합한 위성을 조사함으로써 연안환경 분석과 관련하여 관측 가능한 인자들을 파악하고자 한다. 이를 통해 연안환경 모니터링을 보다 체계적으로 수행하기 위한 인공위성 기법의 특징들을 이해하는 것이 본 연구의 목적이다. 향후 서해안지역의 연안 환경 변화 탐지를 위한 알고리즘을 구축하여 한반도 연안환경분석을 위한 인공위성의 유용성을 검증할 계획이다.

This study aims to propose safety culture design to ease to find out and control behavior characteristics of Korean seafarers. By empirical research of 377 Korean seafarers, the result revealed that significant characteristic of Korean seafarers was "affection to others" and custom of Confucianism affected Korean maritime society prevalently. But there were no significant differences between groups, such as rank, age, gender and sailing route with vessel type except educational background. Furthermore, this study concluded that positive reinforcement was more useful than negative reinforcement to promote safety operation of vessels. Regarding the vessel's safety management, the fact that means for vessel's safety management are linked only to the levels of educational background suggests that the efficiency of vessel's safety operation would be achieved by introducing suitable safety management system depending on the level of educational background.

The port is a space where maritime transport and land transport intersect and is an essential industrial infrastructure for international trade. Therefore, it has a very important function in the national economy. Although the space and the physical facilities of a port are important, it is also very important to efficiently manage and operate these port infrastructures. The government introduced the Port Authority System to strengthen the efficiency and professionalism of port management operations. Since the port authority systemis based on port autonomy, the independence and autonomy of the port authority are very important in port management and operation. Nevertheless, the Port Authority is not functioning properly because the government interferes excessively with the operations of the Port Authority. Therefore, it is suggested that the legal system should be improved to strengthen the autonomy of the Port Authority (PA). This study examines the perception of the legal system that needs to be improved to strengthen the autonomy of the Port Authority, and suggests policy measures for Port Authority workers, civil servants, port companies, and civic groups.

The administrative ship, Chuja-ho, is the only mode of transportation between manned islands in the Chuja-do, Jeju. Chuja-ho is a 25-year-old age, which is identified to pass the persisting period (25 years) for public ships, and there is an urgent need for a replacement. The residents of the island are also requesting that the new administrative ship be outfitted with medical functions because there is no sea transportation system for medical emergencies in Chuja-do. The purpose of this study is to examine the required functions of a new administrative ship outfitted with medical functions and to suggest a conceptual design. In order to review the necessity of an emergency patient transport system, user requirements were surveyed and analyzed, and the ship's condition assessed by ship experts who carried out an on-site survey and analysis of ship survey data. Thereafter, a conceptual design for a new administrative ship with medical functions was presented. The results of this study can be used during a review of a new budget plan and for basic ship designs during the replacement project by the local government. It is also expected to improve the safety and medical environment of Chuja-do residents.

This paper is aims to build the advancement structural model of GICOMS through identification of required system and improvement for implementation of e-Navigation. We derived nine improvement subject for model of advanced GICOMS through the analysis of problems for GICOMS and brainstorming with expert in the maritime safety. And we analyzed the structure of nine improvement subject using by FSM(Fuzzy Structural Modeling) method, and proposed a structural model that to grasp the correlation between elements. As a result, we found out that "advancement of GICOMS" is the final goal, and "improvement a system of information production", "improvement a scheme of information providing", "linkage between GICOMS and VTS" and "building global networks for safety cooperation" are located lowest level. Especially, "advancement of GICOMS" is influenced by "advancement function of VMS" and "Activation of usage" on middle level. We suggested that utilizing state-of-the-art IT facilities, equipment and expertise to improve and enhance the user-centered transition such as maritime workers for advancement of GICOMS based on proposed structure model.
