Due to implementation of legislations for translation poor such as handicapped people, elderlies, children most public buildings are now integrating barrier free design methods. However, barrier free design is still considered as constraints of physical elements that only serve to meet functional aspects for minors and conflict with designs of the space. The authors believe that it is time that barrier free design is considered not as constraints but opportunities that both meet functional and aesthetical needs serving the growing population of transportation poor and others as well. This paper has looked into characteristics of transportation poor and barrier free design elements of passenger terminals and developed 4 categories of design methods. applied by using human sense, form, furniture, and architectural elements. Then the authors analyzed Gunsan International and coastal passenger terminal existing conditions which is considered to be designed to meet barrier free guidelines and legislations through the developed design categories and elements. The result turned out that the subject in regard of barrier free designs for transportation poor lack various applications such as forms that can be used as symbolic and directional elements that assists as wayfinding cues. Also, flexible and multi functional approaches in furniture arrangements, structural approaches are needed.

Recently, it becomes to be very important to reduce the cabin noise of passenger ship, according to the trend of speedy and luxury ship. The noise reduction and control techniques should be considered as important factors from the viewpoint of the sound problem of cabin. Therefore, ship designer has to improve the sound quality as well as to redece the sound pressure level in cabins. In this paper, for the new approach of these problems, we tried to find the trends of noise and sound quality of high-speed coastal passenger ships. Loudness, roughness, fluctuation strength, and sharpness are selected as the parameters for the evaluation of sound quality. The parameters are calculated by using the sound measured in cabin while the ship is running. Furthermore we tried to find the trend of each parameter in cabins and compare with that of sound pressure level. As results, we find that the loudness is linearly proportional to sound pressure level. But, the other parameters show different trends which may be caused by ship motion on the wave and fluctuation of propelling power.

본 논문에서는 사회네트워크 분석 기법을 이용하여 2005년부터 2013년까지 운용되었던 국내 연안여객선의 항로를 분석하였다. 분석결과 연도별로 중심이 되는 항구가 변화되는 것을 확인할 수 있었다. 목포는 지속적으로 가장 높은 연결 중심성을 보였으며, 여수는 최근 그 중심성이 높아지는 것을 확인하였다. 또한 물동량과 이용량 등 전통적인 방법을 통하여 분석한 결과와 사회 네트워크 방법으로 분석한 결과 값을 비교하였는데 이 두 값이 매우 강한 상관관계를 보였다. 이를 통해 전통적인 방법을 사용하지 않더라도 네트워크 분석을 통해 해당 항구의 중심성을 알 수 있음을 확인하였다.

This study proposes a cost-effective method to monitor coastal environments using e-Navigation-implemented domestic and international ferries, and to analyze big data of records such as wind, temperature, salinity, waves, and currents that are gathered through e-Navigation system. First, we present the concept and architecture of e-Navigation operation system based on the General Information Center on Maritime Safety and Security. Then, the marine observation system that can be applied to ferries operating in our nation's territory is discussed. Analytical methods, such as spatio-temporal mixed effects model, ensemble method, and meshfree method, in handling real-time big data obtained by the e-Navigation observing system are then explained in detail. This study will support the implementation of the Korean e-Navigation project that focuses on the safety of small vessels such as coasters and fishing vessels.

To prevent the Sewol incident again, by which the victims are 294 dead and still 10 missing, this study analyzed the change of safety consciousness of passengers onboard ship comparatively before and after the Sewol incident. The survey had performed 2 times at Jeju coastal cruise terminal at February 2014 and May 2014, and effective respondents were 394 and 401, respectively. After the Sewol incidents, the answers' ratio that they would follow the routes that the crews show and they would follow the crews' evacuation guides are decreased 24.5% and 18.5%, respectively. This means that the reliability on the crew members were decreased. Although 77.6% passengers responded that they felt nervousness onboard ship, 60% did not take safety lesson(s) and 45% did not know how to wear a life jacket. And also over 50% did not check the evacuation route map and the location of lifeboat, respectively. Meanwhile, 86.9% respondents answered the system of safey lesson should be changed, which has normally done by TV set.

2020년 AIS 자료와 해양용도구역 정보를 종합해 월별/해역별 주요 선박 통항로를 분석하고 우리나라 연안의 주요 선박 통항로 영역을 유효·비유효 구역으로 구분하여 향후 빅데이터 기반의 통합 항로 예측에 적용하는데 활용하고자 한다. 이 결과를 선박 해양사고정보, 해양에너지, 수산 등의 해양공간계획(MSP) 정보를 추가·분석할 예정이다. 나아가 국가어항을 중심으로 항만별 분석, 화물선·여객선·어선 중심의 선종별 분석 정보로 확대하여 빅데이터 기반의 항로 예측 기술의 입력자료로 활용할 예정이다.

선박이 운항중 타선과의 충돌상황을 효과적으로 신속하게 파악하는 데 도움을 줌으로써 선박 충돌사고를 방지하기 위한 선박충돌위험도 식별시스템을 개발하였다. 지난 연구에서는, 고안된 시스템의 성능을 검증하기 위해 부산항에서 일어난 제품운반선과 화물선간의 충돌사고의 실제 AIS 데이터를 이용한 재생시뮬레이션을 수행한 바 있다. 본 논문에서는 선박충돌위험도 식별 시스템의 테스트베드를 구축하였고, 실제 해상에서 AIS 신호를 이용하여 성능을 검증해 보고자 하였다. 이를 위해, 군산항과 인천항의 연안여객선에 테스트베드를 장착하고, 실제 운항중 AIS 정보를 이용하여, 실시간으로 선박충돌위험도 식별시스템의 온보드 시험을 수행하였다. 본 논문에서는 선박충돌위험도 식별 시스템의 테스트베드의 특징과, 실제 해상에서 수행된 온보드 시험 결과에 대해 소개하였다.

This paper aims, first to analyse the profitability of coastal passenger ships deployed on both subsidized and non-subsidized routes, ie competitive routes, in Korea, second to evaluate them by route, by ship type, and by ship size, and finally to identify whether the ships deployed on subsidized routes are justifiable to receive subsidy from the government. They are followed by the analyses on the profitability of all ships on the coastal routes and their dependence rate of subsidy. The research covers the period of 1995-1997. The research results say that 35% of the total subsidized routes has more than 90% of subsidy dependence rate and that some monopolized routes among subsidized ones with moderate rate of profitability need to be crossed out from the list of subsidy beneficiary. In addition, some ships deployed are not appropriate type in terms of characteristics of route and traffic. One of implications drawn from this study is that the government has to set up a watchdog to monitor subsidized routes, which enables to make them competitive and save the budget.

The Purpose of this study is to improve the deterrent factors in Korea's coastal passenger shipping 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.
