Traffic routes typically have heavy traffic. Especially, the entrance of the route has a high risk of accidents occurring because of ships entering and exiting the port. However, almost of studies have focused on the distribution of traffic on the route. Thus, studies on the distribution between ships for passing through the route are insufficient. The purpose of this study was to analysis the traffic in the Busan north port No.1 route for one week. Based on present traffic conditions, one gate line was settled on the route with an analysis of traffic conditions. Based on the analysis data, each optimal time probability distribution between ships was divided into inbound/outbound and traffic volume. An analysis of the optimal probability distribution, was applied to 31 probability distributions divided into bounded, unbounded, non-negative, and advanced probability distribution. The KS test was applied for identifying three major optimal time probability distributions. According to the KS test results, the Wakeby distribution is the best optimal time probability distribution on the designated route. Although the optimal time probability distribution for other transportation studies such as on vehicles on highways is a non-negative probability distribution, this distribution is an advanced probability distribution. Thus, the application of major probability distribution for using other transportation studies is not applicable to this study Additionally, the distance between ships in actual traffic surveys and the distance estimated by the optimal probability distribution were compared. As a result of the comparison, those distances were fairly similar. However, this study was conducted in only one major port. Thus, it is necessary to investigate the time between ships and calculate a traffic volume on varying routes in future studies.

중대한 해양사고를 예방하고 잠재적인 해양사고의 원인을 제거하기 위하여 해상교통안전진단 제도가 "해상교통안전법" 개정('09. 5. 27)을 통해 정식 제도화되었다. 법 시행 이후 수행된 연구 중 하나인 '해상안전진단제도의 기술기준 및 고도화 연구'에서는 관련 평가 중 하나인 해상 교통혼잡도 평가에 사용되는 환산교통량 및 표준선이 현재 선박의 대형화 및 고속화 추세를 반영하고 있지 못함을 제시, 개선의 필요성을 말하였다. 이에 먼저 관련한 일본의 이론과 국내 진단대행업자의 평가 이론 현황을 파악 분석한 바, 이론 및 진단대행업자 별로 분석요소들을 다르게 사용하고 있어 표준화의 필요성을 발견하였고 또한 2010년 선박 입출항 통계를 이용한 선박현황을 분석한바 이론에서 사용하는 표준선과는 상당이 차이가 있음이 나타났다. 이후 관련 개선을 위한 기술기준(안)을 제안하여 전문가들의 의견 수렴과 이를 분석한 결과, 비록 소수의 상반된 의견이 있었지만, 표준선 변경에 따른 환산교통량 변화가 해상교통혼잡도에 미치는 영향은 그리 크지 않음을 알 수 있었다. 마지막으로 평가관련 개선을 위한 최종 기술기준(안) 및 앞으로 발전방향을 제시하여 해상교통 혼잡도 평가 발전을 위한 연구기반을 마련하고자 하였다.

항만물류산업은 서비스가 무형적이며 생산과 동시에 판매되어 소비되는 즉시성 및 비저장적인 특성으로 인해 정보의 이용, 관리 및 흐름이 중요하다. 최근의 정보통신기술의 발전은 정보의 이용 및 흐름을 위해 여러 가지 기술들을 등장시키고 있으나, 항만물류산업은 공공성이 강하여 여러가지 제약이 따르는 제약성, 해상운송선박의 불규칙한 입출항 패턴과 관련한 불규칙성, 노동집약적인 특성으로 인해 적극적으로 도입이 되지 못하고 있는 실정이다. 따라서, 디지털 경제의 확산에 따라 변화하는 환경에 적극적으로 적응, 대처하기 위해 항만물류산업의 정보화 및 e-비즈니스 도입을 가속화하며, 최근 B2B 전자상거래 프레임워크로 전세계적인 표준으로 자리잡고 있는 ebXML을 항만물류산업에 적용하여 항만물류산업에서 e-비즈니스를 원활히 수행하기 위한 기술적, 관리적, 제도적 전략 계획이 수립되어 할 것이다. 본 연구는 우리나라 국가표준으로 채택된 ebXML을 항만물류산업에 선도적으로 도입하기 위한 연구로서 항만물류산업의 환경 및 현황을 분석하고 ebXML을 항만물류산업에 효과적으로 적용하기 위한 목표모델을 설계하며, 아울러 실행전략을 수립하였다.

Buoys are a necessary component for the safety of vessel traffic. However, if the buoy becomes inoperable from damage and loss, it can have significant impact on vessel traffic safety as well as unexpected budget spending. The purpose of this study was to evaluate the risk of accidental contact by applying the marine traffic assessment index that can reflect the traffic flow in the sea area. First, Busan Port No. 5 fairway, with a high number of buoys and many contact accidents, was set as the sea area for assessment. to investigate the status of accidental contact and evaluate risk of contact accidents based on the IALA Waterway Risk Assessment Programme (IWRAP MkII) and Potential Assessment of Risk Model (PARK Model). As a result, buoys are near the P recautionary Area wherein the traffic flow was complicated by the Masan port vessel and Busan new port vessel, and buoys are near the entrance of the Gadeok waterway, wherein vessels show a pattern of navigation across the fairway and buoys are near the breakwater in the inner fairway were considered as high risk for contact accidents. This study can be used as basic data for establishing an integrated model to evaluate the risk of buoy contact accidents.

The approaching waters of Po-hang port will be increased the traffic volume and passage of larger vessel according to the opening of Young-il new port in 2006. But the adjacent area of Po-hang port still exist the danger elements of safe navigation, the disordered navigation and traffic congestion. Therefore the safety of traffic must be improved in Po-hang vicinity area. This paper describes the status of marine traffic flow and navigational characteristics based on the marine traffic survey using the exclusive software, and the results of marine traffic survey classify into the ship's types and tonnage and track history of passing ships through the statistical method. Finally the examinations of main traffic route, traffic flow and navigational characteristics are discussed, and these results can be utilized the best design of ship's routing at the Po-hang approaching water.

The purpose of this study is to propose the effective method to improve the competitive power in the Busan container terminal. To achieve this, we analyzed the present of the shift pattern in the container terminal, and identified the problems in the pattern. This study shows the issues of shift pattern for field employee in Busan container terminal and also improvement plan to solve them. We suggested two approaches as an effective approach; the flexible use of employees through overtime, use of workers pool among terminals, and outsourcing; the promotion of welfare by leisure, fitness, and community service.

Since July 2006, marine traffic safety management system have been enforced to support the vessels transiting across the coastal area and the vessels coming in and out of ports in southwestern coastal area where heavy traffic density and marine casualties occurred frequently. The marine traffic volume for the marine traffic environmental assessment was measured by the information from RADAR and AIS system in the area. The distributions of marine casualties were analyzed in the main routes and traffic separation schemes during the last five years and the navigational dangerous elements were investigated with the influence of natural environment, the distribution of fisheries and survey questionnaire. Marine accidents of merchant ships have a tendency to decrease gradually but in case of fishing boats, the rate of marine accidents have a contrary results in this area during the last five years. The dangerous elements on navigation appeared to be the dense force from June to August, fisheries activities and the vessels which not follow the compulsory watch on VHF-band radio communication equipments.
