부산항만은 관리하는 범위가 넓고(용호만-부산신항) 노후화 시설이 다수 차지하여 인력만으로 관리하기에 한계가 있다. 이러한 한계를 극복하기 위해서는 새로운 방법이나 기술도입이 필요하다고 판단된다. 따라서 본 연구에서는 부산항만시설 중 인력운영의 사각지대를 대상으로 IoT 기술을 통한 모니터링 시스템 구축을 통하여 보다 넓은 영역의 시설물을 효율적으로 관리할 수 있는 방안을 ${\cdot}{\cdot}$ (중략) ${\cdot}{\cdot}$.

Keep pace with economic development, the quality of transportation means such as railway, road, harbors has changed and those changes have affected to economic activities. It means that economic development and the changes of transportation quality have an inter-systemic relationship. So to speak, transportation means are major factor of national economic activities to implement economic and consumption activities by promoting supply of goods through the network between regions and industries. Currently, it is needed to connect railway and road between South and North Korea due to the economic cooperation of two sides and meeting of separated families based on the peacemaking mood. Moreover, to connect to T.C.R. and T.S.R. route will contribute to save time and cost of transporting freight to Europe comparing with shipping when South-North railway is connected. The possibility and method of connecting railway between South and North Korea will be introduced in this paper.

Delaying and objection for the construction of storage spent-fuel disposal has prompted to consider expanding on-site storage of spent reactor fuel since it can eliminate the need for costly and difficult shipping and control of the spent fuel completely under the direction of the owner-utility. The dry storage unit developed in Canada can accommodate Korea heavy water reactor fuel elements and become a candidate for the Korean market. In this paper, finite element analyses were carried out in order to investigate the structural behavior of the nuclear spent fuel dry storage system, which is subjected to impact loads such as collision of a truck load and dropping of flask under the irregular operation.

퍼지 ART 알고리즘에서 경계 변수는 패턴들을 클러스터링하는데 있어서 반지름 값이 되며 임의의 패턴과 저장된 패턴과의 불일치(mismatch) 허용도를 결정한다. 이 경계 변수가 크면 입력 벡터와 기대 벡터 사이에 약간의 차이가 있어도 새로운 카테고리(category)로 분류하게 핀다. 반대로 경계 변수가 작으면 입력 벡터와 기대 벡터 사이에 많은 차이가 있더라도 유사성이 인정되어 입력 벡터들을 대략적으로 분류한다. 따라서 영상 인식에 적용하기 위해서는 경험적으로 경계 변수를 설정해야 단점이 있다. 그리고 연결 가중치를 조정하는 과정에서 저장된 패턴들의 정보들이 손실되는 경우가 발생하여 인식율을 저하시킨다. 된 논문에서는 퍼지 ART 알고리즘의 문제점을 개선하기 위하여 퍼지 논리 접속 연산자를 이용하여 경계 변수를 동적으로 조정하고 저장 패턴들과 학습 패턴간의 실제적인 왜곡 정도를 충분히 고려하여 승자 노드로 선택된 빈도수를 가중치 조정에 적용한 개선된 퍼지 ART 알고리즘을 제안하였다. 제안된 방법의 성능을 확인하기 위해서 실제 운송 컨테이너 영상들을 대상으로 실험한 결과, 기존의 ART2 알고리즘이나 퍼지 ART 알고리즘보다 클러스터의 수가 적게 생성되었고 인식 성능도 기존의 방법들보다 우수한 성능이 있음을 확인하였다.

Ship Pilotage is one of the most important parts in the construction and development of Shanghai International Shipping Center as it has the fundamental function for the promotion and speed-up of the ship navigation and cargo operation. Recently, Shanghai Maritime University and Shanghai Harbour Pilotage Administration Station had carried out a research project of 'Study on Ship Safety Pilotage in the Shanghai Harbour by Way of FSA (Formal Safety Assessment)'. The aim of this project is to put out some proposes of the decision-making for the improvement of the safety pilotage in Shanghai habour through the way of the FSA. Now these proposes of the decision-making have been adopted and conducted in practice and satisfactory results have been achieved. In the paper, some detailed information, methods and ideas about this research project have been introduced and explained for improving the safety pilotage in Shanghai Harbour.

This paper is a study of the relationships between trade and transshipment in Korea. Through the analysis of the data collected, a comprehensive model has been developed to analyze and predict relationships between trade and transshipment. By using analyses of port and trade evolution in Asia, the model identifies some important results. An application of the model to forecast developments in selected regions in China is also included in this paper. The paper provides a basis for shipping companies to decide on appropriate transshipment port strategies, and provides important theoretical references for Korean ports' development Supported by Shanghai leading Academic Discipline Project, project Number: T0602.

In order to take TC forecasts from different observatories into consideration, and make quantitative assessment and analysis for avoiding TC routes from the view of safety and cost, a new safe-economic decision making method of TC avoidance routing on ocean was put forward. This model is based on combining forecast of TC trace based on neural networks, technical method to determine the future TC wind and wave fields, technical method of fuzzy information optimization, risk analysis theory, and meteorological-economic decision making theory. It has applied to the simulation of MV Tianlihai's shipping on ocean. The result shows that the model can select the optimum plan from 7 plans, the selected plan is in accordance with the one selected by experienced captains.

해운 항만의 환경이 2000년대 들어서 10,000teu급의 대형 컨테이너선박이 집중 투입되면서 선박의 대형화와 고속화가 가속되고 있다. 이에 따라 전세계 해운시장의 업계들은 살아남기 위한 방안으로 M&A와 Alliance들을 선택하였다. 각각의 선사들은 주력하고 있는 항로들이 다르며 그에 따라 전략적인 제휴관계를 맺고 있다. 본 연구에서는 전 세계 해운 선사들의 Alliance 관계를 파악하고 그들의 사회연결망기법중의 하나인 Net-miner4를 활용하여 네트워크 구조에 대해서 깊이 있게 살펴보았다.

The main function of most ship management companies in Korea has been crew manning for foreign shipowners i.e. limited management whereas those in Norway. U, K Hong Kong Singapore and etc. have been largely involved in full management which includes ship operation maintenance and repairs chartering financial administration accounting insurance etc not to mention crew manning The shortage of supply of seamen caused by deindustrialisation and increasing GNP tends to deteriorate the profitability of ship management companies in Korea. In these circumstances they may have to expand their present business to full management in order to continue to be going concerns, This paper evaluates the roles and performances of ship management companies in Korean shipping sector during the last three decades and suggests some ideas in order to develop them identifying major barriers against their development and analysing business activities of ship management companies in advanced maritime countries.

It is important to predict price of agricultural products accurately to government, local government, bodies in charge of agriculture. Production and shipping of agricultural products are affected by weather condition significantly. In this research, prediction model of a Chinese cabbage which is highly sensitive to weather condition is proposed using deep learning technique. After performance of proposed model and a model of previous research is compared, superiority of proposed model is proved.
