본 논문에서는 AIS의 표준 메시지 포맷과 사양을 확장하여 선박의 항해안전을 향상시키고 AIS시스템의 활용을 극대화할 수 있는 AIS 데이타 응용 포맷과 사양을 개발하여 제안하였다. 그리고 국내에서 적극적으로 활용되기 위해서 필요한 6비트 체계를 사용하는 AIS통신에서의 한글메시지의 구현방안을 제시하여 메시지의 한글화 및 단말기의 한글화 방안도 마련하였다. 테스트 결과 개발된 포맷들은 여객선의 운항관리나 교통방송, 어선의 입출항 및 어획량 보고, NAVTEX정보, 구난정보, 기상정보등을 전송할 수 있게 되어 그 활용범위는 광범위하고 특히 GPS플로터나 ECDIS같은 전자해도 기반의 항해시스템과 연동되면 선박의 해양사고 발생을 미연에 방지함은 물론 해상교통안전 향상 및 사고취약선박에 대한 안전향상에 큰 도움이 될 것으로 기대된다.

풍랑특보는 우리나라 부근을 항행하는 선박 및 해상 업무 종사자에게 큰 영향을 미친다. 이 연구에서는 최근 11년(2010-2020년) 동안 기상청에서 발표한 서해·남해·동해의 앞바다 및 먼바다, 제주도 앞바다의 풍랑특보와 주요 해양기상부이의 관측자료를 비교·분석하여 풍랑특보의 적절성을 평가하였다. 각 해역에 대한 풍랑특보와 해양기상부이 관측자료를 일별, 월별, 연별로 통계를 내어 연평균, 월평균, 계절별로 비교한 결과, 풍랑특보의 적중률이 전 해역에 걸쳐 매우 낮은 것으로 분석되었다. 해상에서의 풍랑특보가 어선의 어업활동, 여객선 운항 및 관광, 해상 레저활동 등에 미치는 영향을 고려할 때 해양기상 예·특보의 정확성을 개선할 필요가 있음을 확인하였다.

The purpose of this study is to activate Korea's coastal passenger shipping by improvement of the deterrent factors on the basis of field data collected in order to help stimulate it and enhance its competitiveness. As the representative model of this study, the "P" car-ferry liner was chosen, whereby various deterrent factors were observed in the course of the SWOT analysis and through the questionnaires. The major deterrent factors in summary were inflexible government regulations for additional ship operation, disadvantages of taxes policy, port facility shortages, non-allowing of ship's night operation, complicated and inflexible ship's operation controls by the concerned authorities, unreasonable divisions of steaming areas, and existences of obstacles on the ship's running routes, etc. which considered all are important to activate the liners.

With the increasing needs on various leisure activities, the users of passenger ships and cruisers have been increased year by year. Although over 15 accidents per year betide on domestic passenger ships for last decade, the researches on the safety of crews and guests on boards are difficult to find. This study performed the comparative analysis by experiments on the evacuation characteristics between experience levels on board a training ship. The followings are the results. From the seniors' experiments, it is found that more various evacuation scenarios have to develope and drill as a part of education contents. And from the freshmen's trials, the importances of the evacuation education and the roles of existing crews on evacuation guides are pointed out as to increase the safety of new crews and/or guests who are not accustomed to onboard a ship. On the other, it is explained that the communications between evacuees are worthy and useful, and also save more evacuation times. And on the viewpoint of evacuation methodology, it is clear that captain and evacuation-related crews have to control all the evacuation passages and evacuees of each passages to save more lives.

The International Maritime Organization (IMO) adopted the International Convention on the Control of Ships' Air Pollutants and Discharge as it became interested in environmental issues such as global warming and air pollution. In addition, a special bill on the improvement of air quality, including in port areas, has recently been enacted in Korea to reduce the amount of fine dust generated. As part of such fine dust reduction measures, feasibility studies have been underway on converting diesel engines into battery electric propulsion systems that do not cause fine dust and emissions. Since the battery electric propulsion system can easily utilize renewable energy sources, and does not generate exhaust gas due to combustion of fuel, small coastal ferries with battery electric propulsion systems that use renewable energy have been operating in Europe and the U.S. for several years. However, they have not been introduced in Korea. Therefore, in this study, we selected small coastal ferries in Korea as target ferries, and performed simulations to study the applicability of electric propulsion with batteries linked to solar power systems. Based on the results, we want to confirm the applicability of battery electric propulsion.

In this paper the benefit was forecasted for traffic safety facilities to be constructed along the inland waterway between Phnom Penh and Chong Kneas(Siem Reap) port in Cambodia. First of all, the number of cruise ships passengers and cargo volumes were predicted. Second, the traffic volume of the cruise ships and cargo ships were calculated according to the prediction. Last, the safety benefit of traffic safety facilities was forecasted with the traffic after surveying the waterway accidents. The other benefit was also presented by converting the effect of relieving the emotional burden of navigators into currency value. Accordingly the entire benefit was estimated to be $14,990, $20,950 and $28,540 for pessimistic, moderate and optimistic prospects, in 2011. And then the entire benefits are calculated as $28,320, $63,060 and $95,230 for each prospect in the final estimation year 2020.

I have been analyzed the marine accidents during 10years(1992~2001) based on the maritime inquire court decision, the results were as follows: 1. The rate of accident occuring were showed fishing boat(69.9%), freighter(12.3%), tanker(4.3%), tug boat(3.8%), passenger boat(2.1%) by the usage. 2. The marine accident had been showed operational fault(67.3%), mishandling of engine equipment(21.7%), meteorological condition, etc(11%) by the reason, most accidents had been occured by the operator fault and rack of experience. 3. The marine accidents had been showed damage of hull and engine(27.5%), collision(24%), foundering(11.3%), fire(3.9%), agrounding(10%), by the kind of accidents. 4. The accidents had been occured (74.6%) at the coastal sea, harbour and (25.4%) at the open sea by the sectors. The accidents of the vessel less than 500ton were much increased (54.3%) also, The accidents were much occured at the time between 0400~0800 hours by the time.

In this paper, 2513 marine casualties occurred in Korean waters, during 1989-1993, were analysed by the Multivariate Data Analysis Method. The main results obtained were as follows : 1. Moat of marine casualties resulted from the human factors such as careless operation and insufficient engine maintenance. Engine trouble accounted for main patten of accidents and great number of accidents occurred in fishing vessels. 2. From the point of view of the damage of human life and properties, accidents took place in cargo ships, passenger ships and tankers were serious, but in fishing vessels, those were not so serious. 3. Grounding, collision mainly resulted from careless operation, however flooding and capsizing were much affected by bad weather and material defect.

In the midst of continuing international recession, the rate of maritime traffic and marine leisure markets are consistently growing. The Republic of Korea controls the marine traffic volume through vessel traffic centers and various other management facilities. Nevertheless, the continuous growth and complexity of marine traffic is resulting in repeated occurrences of marine accidents. Recovery is very difficult in cases of human injuries or deaths caused by marine accidents due to its nature, and the scale of marine accidents is also becoming greater with advanced ship building technologies. Passenger ships, oil tankers, and other such vessels used for specific purposes requires a more detailed navigational status surveillance and analysis, and numerous research has been conducted with an objective for monitoring such special purpose vessels. However, the data elements transmitted from the ocean to the shore station are limited to AIS and ARPA. We are implementing IoT ship sensor collection and a syncing system capable of transmitting various ship sensing data to the shore station, and also proposing a Safe Navigation Status Analysis System utilizing the collected data.

This study is a study to secure accessibility in isolated, neglected and underdeveloped island areas. Theoretically explored ways to utilize UAM(Urban Air Mobility), which has recently attracted attention. This is a study for the important accessibility that is connected to the basic life of island residents. In particular, sufficient preparation time is needed, such as the selection of topics necessary for the change of the transportation service system for access to the island area, the public debate process, and the trial service period. Therefore, the secondary purpose of this study is to provide relevant basic data.
