본 연구에서는 국내 해운회사의 안전관리를 위한 여러 가지 투입요소와 산출요소들에 대한 자료를 설문조사하고, 각 해운회사간의 안전관리체제 이행에 따른 효율성을 DEA 분석법을 사용하여 분석하였다. 1998년~2004년까지 각 해운회사의 안전관리체체의 운영효율성을 DEA 모형으로 분석한 결과, 효율성 평균지수가 매년 감소하는 추세를 나타내었다. 효율성 평균지수가 매년 낮아지는 경향을 보이는 이유는 해양사고 건수, PSC지적 건수, 선박보험료, P&I 보험료는 매 년 감소하는 것에 비해 선박수리비, 선용품비와 선박 불가동일수는 매년 감소하지 않고 오히려 증가하는 경향을 보이고 있는 것이 주요한 원인으로 분석되었다.

본 연구에서는 해운기업의 안전관리체제 운영 지원과 시스템 운영 모니터링 및 운영성과 평가도구로 활용할 수 있는 안전관리체제 운영평가 지표를 개발하였다. 이 지표를 이용하여 안전관리체제 도입을 준비하고 있는 기업이나, 기도입하여 유지 발전시키고자 하는 기업에게 운영 단계별 필요한 지식을 알기 쉽게 종합 수록하여 상시 활용할 수 있는 지침서 내지 컨설턴트 역할을 할 수 있을 것이다. 또한 자체 내부심사 시 및 시스템 운영성과 평가 시 평가도구로 활용하여 시스템의 지속적인 개선 및 발전에 기여할 수 있을 것으로 보인다. 이 지표는 크게 대 기준 11개 항목, 중 기준 33개 항목, 소 기준 447개 항목으로 구성되어 있다.

As the basic study about improvement of yellow croaker drift gill net fishing implement and development of the fishing system, this study drew problem after synthetically analyzing hauling system of yellow croaker drift gill net used in the coast of Chuja Island and tested several characters and analyzed in hauling process with 5 step net hauler model for improving the problem. The analysis results are as follows. When the angle between axises of drum centers was small, it showed the tendency that hauling time was fast. Hauling time was faster when drum was 5 step rather than 3 step. When drum was 5 step, slippery phenomenon was small and hauling was stable. Tension was larger when drum was 5 step rather than 3 step. When drum was 5 step, the range of change of the maximum and minimum value was small and hauling was stable. When drum was 3 step, there was following formula between hauling time (Ht3) and angle between axises of drum centers (Ag) Ht3 : (7.15Hs-0.81) Ag-0.81, when drum was 5 step there was following formula.Ht5 : (6.45Hs-0.75) Ag0.10, here, Hs is hauling speed. When drum was 3 step and hauling speed was 28cm/sec, tension was T=0.08A83-1.60Ag3-0.49Ag+369.56(r=0.99), when drum was 5 step, tension was, T=-0.01Ag3+1.96Ag2-34.05Ag+414.58 (r-0.99), here, T was tension(g).

ISO 9000 quality standards families were established in 1987 and have been started to implement Korean industry since early 1990s. ISO 9000 standards families of 1987 were revised in 1994 and 2000, respectively, by request of world wide certification bodi

This study was conducted in order to improve the automatic fishing operation system for anchovy boat seine by comparison with the fishing gear geometry and efficiency using the labor saving nets and the combined type net with midwater trawl. Field experiments were carried out to observe the geometry of nets and improve the fishing operation system by catcher boats. The vertical net opening of fore wing net, square, fore bag net and after bag net of the combined type net were varied in the range of 9.9~12.9. 16.2~28.2, 6.8~12.1 and 9.5~15.2m respectively, when the towing speed was 1.0m/sec and the distance between boats were 100m, 200m, 300m. The vertical net opening of the combined type nets was gradually decreased as function of with increasing the distance between catcher boats. Labor saving net which was maintained the net opening and towing depth stable was more suitable for the automatic hauling operation system by improvement of bag net rather than the combined type nets which was impossible in swallow depth and near to anchovy school. 3 boats hauling operation system of the labor saving net was carried out by crane with power block in 2 catcher boats for improvement of hauling operation and pushing equipment of anchovy cooking system in the processing boat for maintain more anchovy in dry frame. From the results of field experiments, 3 boats hauling operation system with power block and improved cooking system was very 3 boats hauling operation system with power block and improved cooking system was very useful and more practical as hauling time 20~35min and No. of fishermen 12~13 in comparison with the traditional system such as hauling time 30~50 min and No. of fishmen 28~38.

In order to enhance the quality of the glass bottle and to preserve the contents long, corrosion of the bottle surface is often required. The corrosion operation consists of dangerous and harmful tasks using strong acid such as HF. Thus, the corrosion operation should be automatized to improve the worker's safety. The first step of the automation is to develop the bottle gripping system that automatically grips and fixes the bottle during corrosion operations. The gripping system consists of holders, holder plates, air cylinders, and bottle aligning system. This paper shows the gripping system development procedure.

This study develops a improved gate assignment algorithm and decision support system using its algorithm to extract a assignment result minimizing a walking distance of passengers in airport and maximizing the utilization rate of avaliable gates in domestic airports. By operation support system, it may contribute greatly in efficient enlargement of airport operation and increase the airport reliability through quickly coping with takeoff and landing delay of flight due to weather change, preservation and repair of gate, etc. Also, passengers who use airport terminal can minimize time and walking distance for departure, arrival, and transit, and it may greatly reduce the additional operation cost for common gates through maximizing the utilization rate for exclusive usage gates for airplanes which use gates.

An operational strategy for inventory control on finished goods in the distribution system has been given attention to many enterprises and many studies regarding this field have been done and is also on-going currently. Many of these studies represented a large scale distribution network with a unified formulation by using defined symbols. These methods have provided the systematic approach of the distribution network but they are impossible to applying the reality system due to not considering the service rate of demand and treating the shortage of inventory. In order to overcome these unrealistic problems, the novel safety stock policy of responding to customers' inventory distribution network is suggested. this paper explores the transportation between Central Distribution Center(CDC) and Regional Distribution Center(RDC). Especially, the relation of transportation cost between CDC and RDC and cost of inventory control according to safety inventory with service level are emphasized. We could obtain the good results of this study by determining the optimal safety stock considering the various variables and constraints.
