Amid of the logistics hub center competition is going to intensifying between the world major port, it is essential to pre-occupied the base in the logistics hub world take advantage of advanced technology of logistics equipment than other ports. In existing container terminal, when container moves the terminal use the omnidirectional and directional antenna in order to exchange data information on the basis of 802.11 wireless network system. Case of loading height of exceeding, the blind sport will occur and a limited frequency channel can't help using in the area. A limited frequency channel usage and nested areas happen to use the closed terminal, it has a great influence to operate the terminal working. In this paper, LTE network is configured provided by the specified company ('L' Corp,.Ltd) and terminal data extracted through LBO (Local Breakout) in the cell site which is configured directly with container terminal operation server. Using this method, container terminal yard equipment operate without overlapping arises with uninterrupted data presented for ways to efficiently. I would suggest both the existing wireless AP LAN configuration of container terminal and new LTE system and applied to the real yard operating devices situations. Through these methods presented comparative the existing network traffic with new constructed LTE configuration. I admired to suggest that wireless network LTE introduction is fundamental factors to get rid of the blind spot, the problem of limited frequency channel and overlapping arises. These essential points can be a continual improving terminal services and more efficient terminal operational management.

The Moving Search Radar System (MSRS) monitors sea areas by moving along the coast. Since the radar is initially aligned to the front of the vehicle, it is important to know the changes in the heading azimuth of the vehicle to quickly acquire the target azimuth from the radar after the MSRS has moved. The heading azimuth can be obtained using the gyro compass, the GPS compass or the electronic compass. The electronic compass is suitable for MSRS requiring fast maneuverability due to its small volume, short stabilization time and low price. However, using a geomagnetic sensor may result in an error due to the surrounding magnetic field. Errors can make early automatic tracking of the satellites difficult and can reduce the radar detection accuracy. Therefore, this paper proposes a method to automatically compensate for the error reflecting the correction value on the radar obtained by comparing the reference azimuth calculated by solving the geodesic inverse problem using two coordinates between the radar and the geostationary satellite with the actually-directed azimuth angle of the satellite antenna. The feasibility and convenience of the proposed method were verified by applying it to the MSRS in the field.

Equipments that can transmit maritime distress signals in accordance to Global Maritime Distress Safety System are the followings: A1 water(Very High Frequency, SART), A2 water(MF/HF Radio Equipment), A3 water(INMARSAT), A4 water(Emergency Position Indicating Radio Beacon). Institutions with the capacity to receive distress signals are Korea Coast Guard affiliated radio stations, patrol ships, Rescue Coordination centers, Vessel Traffic centers, Complex problems regarding repetitive distress alarms, inaccurate statistics, multiple control towers are existent. Consequently, effective measurement to resolve dispersed operating maritime distress signal system are in time of need. Moreover, current KCG Headquarter is considering to integrate five distress radio stations dispersed across nation into a single international safety communication center. The integration of radio stations are efficient in terms of information coordination between nations, however, it cannot support efficient response to real-time maritime incident. Therefore, in this study, a new system that can rapidly response to real-time maritime incident will be proposed.

COSPAS-SARSAT 시스템은 위성체와 지상 설비를 이용하여 항공기 또는 선박 등이 조난 시에 탐색구조(SAR: Search and Rescue) 활동을 도울 수 있도록 조난경보와 위치정보를 제공하는 시스템이다. COSPAS-SARSAT 서비스의 경우, 조난신호 접수에서 조난위치확정까지 평균 1시간 이상이 소요되고, 위치정확도가 수 Km 정도로 범위가 넓은 편이다. 이러한 문제점을 개선하기 위해서 중궤도 위성을 이용한 차세대 탐색구조 시스템 개발이 추진 중에 있으며 EU에서 2011년 FOC(Full Operation Capability)를 목표로 개발중인 갈릴레오 항법위성 프로젝트의 경우 SAR 중계기를 탑재하여 탐색구조 서비스를 제공할 계획에 있다. 갈릴레오 탐색구조(SAR/Galileo) 서비스는 수 m급의 위치정확도, 10분 이내의 조난신호 접수에서 구조까지 소요시간, 및 조난자에게 회신링크 서비스 제공 등 보다 향상된 탐색구조 성능을 제공하기 위해 개발 중에 있으므로, 갈릴레오 위성 서비스가 시작되면 탐색구조시스템 체계에 보다 신속하고 정확한 구조가 가능할 것으로 예상된다. 우리나라에서는 COSPAS-SARSAT 회원국으로 가입하여 현재 송도 해양경찰청 내에 LEOLUT와 MCC가 설치되어 운용되고 있다. 날로 더해가는 다양한 재난에 대한 인명구조를 신속하고 효과적으로 대처하기 위해 차세대 갈릴레오 탐색구조 지상국 도입이 절실하다고 할 수 있다. 따라서, 탐색구조 단말기를 포함한 지상국 인프라의 구축 등 갈릴레오 탐색구조 지상시스템 개발의 참여 방안에 관한 연구는 매우 시기적절하고 중요한 연구이다. 본 논문은 갈릴레오 사업에 참여하여 SAR/Galileo 개발을 주관하고 있는 중국의 사례를 분석함으로 우리나라가 차세대 갈릴레오 탐색구조 지상시스템 개발에 참여하기 위해서 필요한 참여방법 및 절차 등을 도출하고, 참여 가능한 개발범위, 참여전략 및 추진체계에 대해서 제안한다.법의 성능을 평가를 위하여 원본 여권에서 얼굴 부분을 위조한 여권과 기울어진 여권 영상을 대상으로 실험한 결과, 제안된 방법이 여권의 코드 인식 및 얼굴 인증에 있어서 우수한 성능이 있음을 확인하였다.진행하고 있다.태도와 유아의 창의성간에는 상관이 없는 것으로 나타났고, 일반 유아의 아버지 양육태도와 유아의 창의성간의 상관에서는 아버지 양육태도의 성취-비성취 요인에서와 창의성제목의 추상성요인에서 상관이 있는 것으로 나타났다. 따라서 창의성이 높은 아동의 아버지의 양육태도는 일반 유아의 아버지와 보다 더 애정적이며 자율성이 높지만 창의성이 높은 아동의 집단내에서 창의성에 특별한 영향을 더 미치는 아버지의 양육방식은 발견되지 않았다. 반면 일반 유아의 경우 아버지의 성취지향성이 낮을 때 자녀의 창의성을 향상시킬 수 있는 것으로 나타났다. 이상에서 자녀의 창의성을 향상시키는 중요한 양육차원은 애정성이나 비성취지향성으로 나타나고 있어 정서적인 측면의 지원인 것으로 밝혀졌다.징에서 나타나는 AD-SR맥락의 반성적 탐구가 자주 나타났다. 반성적 탐구 척도 두 그룹을 비교 했을 때 CON 상호작용의 특징이 낮게 나타나는 N그룹이 양적으로 그리고 내용적으로 더 의미 있는 반성적 탐구를 했다용을 지원하는 홈페이지를 만들어 자료 제공 사이트에 대한 메타 자료를 데이터베이스화했으며 이를 통해 학생들이 원하는 실시간 자료를 검색하여 찾을 수 있고 홈페이지를 방분했을 때 이해하기 어려운 그래프나 각 홈페이지가 제공하는 자료들에 대한 처리 방법을 도움말로 제공받을 수 있게 했다. 실시간 자료들을 이용한 학습은 학생들의 학습 의욕과 탐구 능력을 향상시켰으며 컴퓨터 활용 능력과 외국어 자료 활용 능력을 향상 시키는데도 도움을 주었다.지역산업 발전을 위한 기술역량이 강화될 것이다.정 ${\rightarrow}$ 분배 ${\rightarrow}$ 최대다수의 최대행복이다.는 역할을 한다. 따라

"Sale and purchase brokers" are independent contractors who act as agents for principals intending to seller or buy ships in English Maritime Law. The essential feature is that legal position of shipbroker is largely one of agency. They can be obtained by a study of the Lloyd's Register or the equivalent registers of other Classification Societies, the American Bureau of Shipping and Korean Registers. Such a broker is of valuable assistance to the prospective seller or purchaser. And the broker's liability normally arises in the context of a contract. But, expressed in general terms, those contractual obligations are, in absence of contrary agreement, to act with reasonable care and skilled to obtain the cover requested by his client not to guarantee that such will be concluded and to ensure that the scope of the policy, its essential terms and relevant exclusions are made known to the insured. Acting in this professional capacity, the broker's liability are such that the facts upon which an action for breach of contract may be based may also found an action for the trot of negligence provided that there is shown to be the necessary 'assumption of responsibility' by the broker conveyed directly or indirectly to the insured. This thesis deals with liability of S&P Brokers, the legal problems of ship broking, commission, conflicts of interest and secret commissions in English Maritime Law and the Cases.

With the removal of underwater obstacles in the Busan New Port, the water depth of the pier has been secured up to 17m, and the port authority is constantly responding to the trend of container vessels becoming larger. Also, in 2020, 24,000TEU class container ships are entering to the port, and it is planned to secure the depth in the port to 23 m later in line with this trend. Mega container ships must check in advance the factors to be considered depending on the situation at the time, and for this, it is judged that information sharing among stakeholders is necessary. In this paper, to understand the effect of the corresponding route because of the mega container ships, a transit safety evaluation was conducted based on statistical data on ship entry and departure and maneuver characteristics of corresponding ships. The result showed that the transit of the mega container ships has increased up to 8.4% comparing to the risk of 4,000TEU class container ships. Additionally, safety measures such as minimum safety depth and tug operation plans were presented by gathering opinions on operational characteristics from the perspective of pilotage for safe transit in the Busan New Port area. Through this, it is considered that it will be possible to contribute to the prevention of accidents when entering and leaving the Busan New Port.

According to globalization of world economy by extension of production, sales and distribution all around the world and international transportation system changed into a transport system that puts great importance on speediness and value-added services, international transport system is changing into a Multimodal Transport Routing centered system that systematically connects marine, air and rail transports. Due to such changes production, sales and distribution must be provided in time and Multimodal Transport Routing, which can provide multi-dimensional logistics services to customers of global network, is needed but information connection for international transport and connection system between transport modes are insufficient and can not be activated. Especially in Korea, selection standard of 3rd party logistics companies and transport companies is presented, but logistics exclusive companies, which plan and execute the transportation, can't present a systematic evaluation standard for international Multimodal Transport Routing, selection. Thus, this research surveys important previous studies about Multimodal Transport Routing, selection, derives an evaluation standard for Multimodal Transport Routing, selection through interview with company officials, and presents a theoretical basis for Multimodal Transport Routing, selection through systematic analysis of Multimodal Transport Routing, selection using Analytical Hierarchy Process (AHP).
