본 연구는 국내 액체화물량이 가장 많은 울산항에서 발생한 해양사고 통계자료를 토대로 해양사고 위험도와 취약성을 분석했다. 울산항에서 발생된 해양사고 발생 위험성, 환경피해도, 환경오염사고 취약성에서 상당히 취약한 것으로 드러났으며 분석결과를 바탕으로 향후 울산항에서 발생할 가능성이 높은 해상사고 시나리오와 사고대응전략을 마련하였다. 또한 울산항에서 발생한 대형 해양오염 사고에 대비하기 위한 대응전략으로서 제어장비와 기반인프라를 구축하고 제어센터를 설립하여 해양사고안전 기능을 통합하는 것이 필요하다고 판단된다. 특히, 울산항과 같이 액체화물특화 항만의 경우 물동량의 규모나 해양오염사고의 빈도를 볼 때, 안전관리 상설기관의 유치가 절실하며 안전항만을 구축하는데 필수적으로 고려해야 할 것으로 사료된다.

Today, about 99% of total import and export cargo in Korea is being transported through the port. The general trends of cargo handling show increases in capacity and speed, In order to cope with these trends, it is not only required to raise the efficiencies of port operation and function but also necessary to decide the optimal amount of the skilled labor force for cargo handling in the port. Cargo handling in the port is basically relied on the cargo handling facilities. Therefore, it is very important to reserve the amount of labor force for cargo handling system has been developed up to a certain level but the personnel management system which is the superior structure has not been followed well. In this study, therefore, we show a method to determine the required amount of labor force for cargo handling considering the amount of cargo and type of cargo handling work per each cargo, and the optimal amount labor force in cope with the fluctuation of the basic cargo handling labor force with respect to the time of in and out cargo flow in the viewpoint of minimizing the expences due to reservation of extra labor force than needed and firing employment of labor force using the Dynamic Programming. The derived algorithm is introduced into the computer simulation for Pusan port with the analyzed real data such as amount of cargo handling in the port with respect to working hour, cargo capacity, working step, the ratio of cargo handling facility and actual number of workers and we estimated the required labor force. As a result of analysis the labor force of Pusan port showed the over-employment such as maximum 21.4%, minimum 8.2% when we assumed that the averages of actual working hours and days were 8 hours in a day and 20 day in a month.

최근 갈등의 관리가 주요한 과제로 떠오르고 있다. 그 중 공공정책의 추진에 따라 발생하는 공공갈등은 사회적으로 부정적 효과를 가져올 수 있기 때문에 갈등을 효과적으로 잘 관리하는 것은 매우 중요하다. 이에 본 연구는 항만 관련 공공갈등의 특성을 면밀히 살펴봄으로써 항만과 관계된 공공정책의 원활한 추진을 위한 기반을 마련하고자 하였다. 본 연구는 항만 분야에서 발생한 갈등사례를 다양한 채널을 통해 수집하고 유형화를 실시하여 항만 관련 갈등의 특성을 보다 면밀히 살펴보고자 하였다는 점에서 의의를 지닌다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 본 연구는 주체별, 생애주기별, 쟁점별 특성을 고려하여 항만 관련 공공갈등을 유형화하였으며, 이를 통해 항만을 둘러싼 갈등은 다양한 쟁점을 지니고 있음을 확인하였다. 둘째, 지금까지 발생한 항만 관련 공공갈등은 강제력이 높은 방식으로 종결된 사례가 많다. 다만, 갈등 유형에 따라 합의로 종결되는 사례가 많은 경우도 있으므로 갈등발생시 조속한 종결유도를 위한 판단이 필요하다. 셋째, 항만 관련 공공갈등의 관리를 위해 사전예방, 사후대응의 이원적 체계를 마련할 필요가 있다.

Study of the background and state of Osaka's waterfront space development and analysis of the functions of 22 chosen major facilities of development project reveals the following four types: amenity-oriented development, large-scale synthesis type development, renewal compound area type development, exchange communication promotion type development. Osaka bay area has served primely as the base of harbors, industry and energy, while analysis of the ongoing project has found that the city has been making a functional transition to a type of development to live up to the needs of the times, suggesting that is wise that Korea's future direction of waterfront development be oriented toward environmental-friendly development by taking advantage of low-density area's natural resources. Given the plurality and complexity of the law of coastal zone, what is needed is a legal maintenance for coastal zone's clear-cut coordinating function and for environmental-friendly development with the limitations of seaside and coastal functions in mind.

Logistics in a supply chain network has become an important operational strategy in a competitive market. A number of internal and external risks involved in the logistics operations in a company tend to create problems in fulfilling customer orders. This research presents how ERM (enterprise risk management) can be used to identify, assess, and control logistics risks. An electronic company's logistics activities were used as an industry case to demonstrate a way to identify and assess risks surrounding global logistics function. This paper has further presented action plans to mitigate the impact of the risks that occur.

글로벌화가 진행됨에 따라 물류서비스에 대한 기대수준이 높아지면서 물류센터의 효율화를 도모하는 물류장비의 도입이 물류센터의 경쟁력을 좌우하는 핵심요인으로 부각되고 있는 상황이다. 물류센터에 도입이 필요한 대부분의 물류장비 고가의 수입제품에 의존하고 있어 국내 물류기업으로서 활용이 어려워 국내 독자기술의 개발이 요구되고 있다. 본 연구진은${\cdots}$(중략)${\cdots}$.

In a network router, packet loss may occur when it overflows due to sudden burst traffic. This paper studies how much large buffers are required to eliminate the packet losses. There are buffers on which packet arrive and one output port to which a packet is transmitted at a time. The buffer management algorithm should determine one of the buffers whose packet is transmitted to the output port at each time. The front packet belonging to the buffer determined by the algorithm is transmitted. The goal is to minimize the sum of the lengths of buffers to transmit all the packets. We provide an optimal off-line algorithm and also we show the lower bounds of on-line algorithms. The on-line algorithm has no prior information of the packets having arrived in the future. Its performance is compared to that of the optimal off-line algorithm.

Buildings nowadays are increasingly expected to need higher and more economic performance requirements. Energy consumption in buildings accounts for over 30% of total energy use. The Building Energy Management System (BEMS) and renewable energy (RE) technologies are considered as a potential measure to improve energy efficiency and reduce use of grid-power. It is, however, a challenge to utilise the intermittent energy supply of RE in building energy systems. This paper presents an experimental study on a RE-embedded BEMS. A control algorithm for the RE-embedded BEMS was designed to maximise the utilisation of RE and eventually to reduce electrical utility bill. The proposed system is tested at a laboratorial chamber with an air conditioner, fan and heater. The contribution of RE in building energy system is discussed to this end.

Recently IMO and IALA have developed the strategy of e-Navigation and the concepts of VTM to enhance the safety, efficiency and security of vessel traffic and protection of the marine environment. And current technical and functional trends require vessel traffic management systems to be improved so as to control vessel traffic not only in waters of harbour area, but also within EEZ waters. Under the consideration of these circumstances, a three-layered vessel traffic management system was proposed in this paper. The proposed system consists of three sub-systems, called Local VTS, Regional VTS and National VTS, and those sub-systems are designed respectively to be suitable for managing vessel traffic within their own jurisdiction waters.
