  • 기존의 VTS 시뮬레이터에서 사용되는 시나리오 작성은 선박의 웨이포인트를 기반으로 하여 작성자의 수작업에 의해서 비효율적으로 이루어졌다. 하지만 본 연구에서는 항만별로 수집된 실제선박의 운항정보를 이용하여 자동으로 시나리오를 생성하고, 목적에 맞게 수정, 편집하여 사용할 수 있는 시나리오 생성 기술을 적용한 모듈과 이를 바탕으로 하는 VTS 시뮬레이터 개발을 위한 방법에 대해 논하고자 한다. 항만별 맞춤 시나리오는 항만의 특성이 반영된 실제선박의 AIS기록과 입출항정보(Port-MIS 연계 정보)를 활용하여 VTS 시뮬레이터 시나리오 형식으로 변환되고, 교육자가 이를 가시적으로 확인할 수 있도록 전자해도 기반의 교육자 운영장치에 표시되며, 효율적으로 편집, 저장하고 호출할 수 있도록 생성된다. VTS 시뮬레이터는 이 형식의 시나리오를 바탕으로 언제든지 호출, 시작, 일시중지, 재시작, 정지 동작이 가능하며, 시나리오 내용 변경은 즉각적으로 반영될 수 있으며, 새로운 시나리오로 저장될 수 있어 목적에 맞게 활용된다.

  • In order to effectively relieve the traffic pressure of the city, ensure the smooth flow of freight and promote the development of the logistics industry, the selection of appropriate port logistics location is the basis of giving full play to the port logistics function. In order to better realize the selection of port logistics, this paper adopts the entropy weight method to set up a multi-dimensional evaluation index, and constructs the evaluation model of port logistics location. Then through the actual case, from the environmental dimension and economic competition dimension to make choices and analysis. The results show that port d has the largest logistics competitiveness and the highest relative proximity among the three indicators of hinterland city economic activity, hinterland economic structure, and port operation capacity of different port logistics locations, which has absolute advantages. It is hoped that the research results can provide a reference for the multi-dimensional selection of port logistics site selections.

  • Lockheed Martin has integrated and installed numerous AIS systems around the world as part of several VTS installation contracts and technology demonstrations for customers. Each of these systems incorporates specific customer requirements addressing differing objectives. This paper describes the capabilities and features of Lockheed Martin's current implementation of the Universal AIS system, and the experiences Lockheed Martin has had with earlier AIS and ADS (automated dependent surveillance) system installations. Specific examples are provided for an amphibious landing exercise with the US Army; installations at a Middle-East Oil port; technology demonstrations in New York Harbor, USA; river systems in New Orleans, Louisiana, USA; and coastal applications in the Gulf of Suez. The paper closes a brief overview of the most recent activity, the Turkish Straits VTMIS project that requires Universal AIS installations. The evolution of the technology and lessons learned will be discussed in the context of these examples. The perspective will be on Lockheed Martin's experience working with different customers to integrate AIS technology into a larger VTS or Port Information System. It will also discuss, from the practical side, how AIS information is used by a variety of maritime organizations with differing needs and information objectives.

  • The productivity of port labor in Pusan port is very low and the ratio of port accident is high in comparision with other advanced foreign ports. The aim of this paper is to find why the productivity in Pusan port is much lower than that of other countries in terms of port labor education systems. To obtain the objective of this study, the writers used 163 questionnaire for port labor in BCTOC, PECT and UTC for the survey of training method of cargo equipment handling. The result of this study shows as follows; (1) From the fact that ratio of labor who were trained by KPTI was 2.5%, we could say the public training system of port labor is not operated properly (2) As most of laborers are trained by the experienced associate, they do not recognize how the level of cargo handling equipment is set to increase the productivity. (3) In order that the port public training system plays a good role in port industry, a new license system should be introduced and an expert education system should be developed.

  • 동북아시아 경제의 급성장으로 인한 지역 물동량 및 해운시장 환경 변화에 따라서 부산항과 상해항은 동북아 물류 중심 허브가 되기 위하여 항만개발 및 항만 경쟁력을 강화해 왔으며, 최근에는 환적 컨테이너 화물 유치경쟁이 더욱 심화되고 있다. 따라서 본 연구에서는 동북아 주요 컨테이너 항만중 경쟁관계에 있는 부산항과 상해항을 대상으로 이 두 항만이 피더항의 환적화물을 유치하기 위한 경쟁의 게임모형을 수립하여 경쟁상황을 분석하였다.

  • 최근 컨테이너 선박은 조선 기술의 발달과 세계 경제교역 규모의 급속한 증가에 따라 대형화, 고속화가 빠르게 진행되고 있다. 이에 머지않아 15,000TEU급 컨테이너 선박의 등장이 예상되고 있다. 동북아시아에서는 경제의 글로벌화에 따른 급격한 물류환경 변화에 대응하여 물류 주도권 확보를 위한 물류거점화 경쟁이 치열하게 전개되고 있다. 이에 따라 주요항만에서는 대형 선사를 유치하기 위한 치열한 경쟁을 하고 있다. 이를 위해 본선작업을 신속하고 정확하게 처리하기 위한 노력이 절실히 필요하며 지금까지의 본선계획 시스템은 획기적으로 개선되어야 할 것이다. 그리하여 본 논문에서는 이러한 기존 본선작업의 개선을 위하여 다수의 플래너를 이용한 양?적하 작업계획을 수행하여 보다 신속하고 정확하게 하며, 플래너(Planner)간의 정보공유로 작업계획의 품질을 보다 향상시킬 수 있는 다중분산 본선작업 계획 시스템을 제안한다. 그리고 이의 효율성을 검증하기 위해 아레나(ARENA)를 통한 시뮬레이션을 수행하고자 한다.

  • Recently, BIM has been extended to infrastructures such as roads and bridges, and the demand for BIM standard development for ports is increasing internationally. Due to the low level of utilization of classification system and drawing standards compared to other infrastructures, and the closed nature of national security facilities, ports have insufficient level of connection and sharing environment among external systems or users. In addition, since the standardization of data for port facilities is not made, it is still necessary to establish an independent DB for each system and to ensure interoperability of data between these systems since it does not have a shared environment among similar data. Therefore, the purpose of this study is to develop and verify IFC, the international standard for BIM, in order to cope with the BIM environment and to be commonly used in the design, construction, and maintenance of port facilities. To this end, we build a standard schema with port-specific Express Notation according to buildingSMART International's standard development methodology. First, domestic and international reference model standards were analyzed to derive components such as space and facilities of port facilities. Based on this, the components of the port facility were derived through the codification, categorization, and normalization process developed by the research team. This was extended based on the port BIM object classification system developed by the research team. Normalization results were verified by designers and associations. Then, IFC schema construction was based on Express-G data modeling based on IFC 4 * 2 Candidate, which is a bridge candidate standard based on IFC4 (ISO16739), and IFC 4 * 3 Draft, which is developed by buildingSMART International. The final schema was validated using the commercialized validation tool. In addition, in order to verify the structural verification of the port IFC schema, the transformation process was verified by converting the caisson model into a Part21 file. In the future, this result will not only be used as a delivery standard for port BIM products, but will also be applied as a linkage standard between systems and a common data format for port BIM platforms when BIM is used in the maintenance phase. In particular, it is expected to be used as a core standard for data exchange in the port maintenance stage.

  • Single-port video-assisted thoracic surgery (VATS) has slowly established itself as an alternate surgical approach for the treatment of an increasingly wide range of thoracic conditions. The potential benefits of fewer surgical incisions, better cosmesis, and less postoperative pain and paraesthesia have led to the technique's popularity worldwide. The limited single small incision through which the surgeon has to operate poses challenges that are slowly being addressed by improvements in instrument design. Of note, instruments and video-camera systems that are narrower and angulated have made single-port VATS major lung resection easier to perform and learn. In the future, we may see the development of subcostal or embryonic natural orifice translumenal endoscopic surgery access, evolution in anaesthesia strategies, and cross-discipline imaging-assisted lesion localization for single-port VATS procedures.

  • In these days, there are a lot of studies in the port automation, for example, unmanned container trasporter, unmanned gantry crain, and automatic terminal operation systems and so on. In terms of loading and unloading equipments. we can consider container transporter. This paper describes the automatic control for the UCT(unmanned container transporter), especially steering control systems. UCT is now operated on ECT port in Netherland and tested on PSA ports in Singapore. So we present a design on the controller using neural network PID(NNPID) controller to control the steering system and we use the neural network self-tuner to tune the PID parameters. The computer simulations show that our proposed controller has better performances than those of the other.
