A self-regulatory community fisheries management program in Korea is designed to enhance fisheries resources, to protect fishing grounds of self-regulatory communities, and to manage their fisheries resources by their own regulations and knowledge. This study explored an applicable ecosystem-based management plan based on the scientific investigation and analysis. This study suggested objectives, indicators and reference points of the ecosystem-based resource management system which are applicable to selfregulatory community fisheries. The objectives of the management system are to maintain sustainable fisheries production, to maintain optimum fishing intensity, to reduce by-catch, to conserve spawning ground and habitat, to maintain optimum habitat environment, to increase/maintain abundance of prey species, to increase/maintain stock biomass, and to conduct stock enhancement on the basis of scientific assessment. The improved methods for the assessment and management are introduced by demonstrating a self-regulatory fishery which targets on hen clam in Dong-li fishing village in Busan.

Yongsan river 4th agricultural comprehensive development project is being developed in order to strengthen the competitiveness in the southwest sea-side district, to construct the area for the special product and so on. Different from other development project, this project is to use water from its watershed by means of using regulating reservoirs, small reservoirs and farm ponds. but the number or regulating reservoirs, small reservoirs and farm ponds involved in this project are 7, 147 and 13 respectively. So it is necessary to develope the irrigation water management system for the purpose of efficient water use in Yougsan river fourth district. In this study, the irrigation water management system was developed and by using this system. efficient water using plans could be established.

The purpose of this study was to test system model for family resources management developed by Deacon and Firebaugh. The data were collected by means of a questionnaire destributed to a stratified sample of 600 housewives living in Seoul. The questionnaires specially developed by the researchers contained of 118 items. the coefficient alpha reliability estimate for this instrument was conducted using Cronbach' procedures. The data were analyzed using frequency, percentile, mean, step wise multiple regression and path analysis. The results of path analysis showed that the level of the elements of satisfaction with the management was correlated with demands(the household size, the age of the last child, employment status of respondents), resources(marital satisfaction, health of respondents), and throughput(standard setting, reality in planning, the existence of facilitating conditions). A system model for family resource management received considerabel empirical support. This presumed that the components of demands lead to the lower satisfaction with management. The throughput components were also important in explaining satisfaction with management some of research and methodology issues for the advanced study were suggested.

In 1987, The Brundtland Report defined a sustainable development as the development that meets the needs of the present without compromising the ability of future generations to meet their own needs. This is the concept that we should cling to, to preserve natural resources of the present for the future generation. With this concept in mind, this paper criticized that the current waste management policy has been neglecting resource preservation aspect of waste management policy while giving too much emphasis on reducing waste generation. Thus, the purpose of this paper is to analyze how waste management policy can affect preservation of natural resources, and to investigate policy alternatives that can reduce both the volume of waste generated and the amount of natural resources that need to be consumed in the production process. The study was conducted based on the literature survey and system dynamics simulation. Borrowing Randers and Meadows's solid waste model with some modification of parameter and variables, this paper simulate several policy alternatives to figure out the most effective waste management policy set that can meet the need of the present without compromising the ability of the future generation to meet their own needs. Main concern was how to link waste management policy with resource management policy that can lead to minimization of waste generation and resource consumption.

이동통신과 인터넷 기술의 결합으로 탄생한 무선 인터넷은 휴대의 편리성을 제공하고 있으나 모바일 환경의 제약사항 때문에 대중적인 인터넷 서비스로는 발전하지 못하고 있다. 무선 환경의 제한 요소 중 협소한 메모리 공간으로 모바일 디바이스에서는 효율적인 자원 관리를 수행하지 못하는 단점을 가지고 있다 휴대성이 고려되어야 하는 하드웨어 특성상 충분한 메모리 용량을 확보하는 데에는 한계가 있으므로 향후에는 디바이스 내부의 저장 장치에서 외부의 영역까지 메모리 공간을 확장하여 데이터 처리가 수행될 수 있는 플랫폼 구조로 발전되어야 할 것이다. 본 논문에서는 모바일 디바이스의 내부에서 외부의 서버까지 메모리 공간을 런타임 액세스(Run-time Access)에 의해서 확장하여 데이터 활용을 가능하게 하고 디바이스 내부의 파일을 효율적으로 관리할 수 있는 모바일 에이전트를 제안하며 이를 실현하기 위한 자원 관리시스템(RMS: Resources Management System)을 설계하고 구현하였다. 제안된 RMS를 적용한 디바이스는 '모바일 공간확장'으로 확대된 프로세스 적용이 가능하며 내부 파일을 효과적으로 관리하여 최적의 메모리 공간을 유지하는 효과가 있다.

Up-to-date manufacturing companies have faced a market-driven environment of pull production order. There should be a difference in operating manufacturing resources according to the type, quantity, and delivery time of manufactured products, because the process situation in pull production is changed by customer orders. And it should be taken into account from the stage of preparing for production such as process design and the placement and utilization of manufacturing resources. However, the feasibility of production plans is limited because most of small manufacturing businesses make production/supply plan of the parts and products assuming that equipment abilities in scheduling is sufficient without managing process standard information systemically. In this study, a discrete event simulation system based on BOM (bill of material), that is F-OPIS (online productivity innovation system), is introduced and a case study on application of the system leading to improving productivities is presented. F-OPIS deals with a decision-problem on production management and it is specialized for small-and- medium sized manufacturing companies. The target company of this case study is a typical small-and-medium sized manufacturing company in Korea, that produces various machined parts. The target company adopts make-to-stock production management to prevent tardy delivery because of fluctuations in demand. Therefore, it is required to apply an efficient inventory control solution for improving productivities. In this paper, based on the constraints of working capacity of manufacturing resources, the bottleneck process is analyzed as production conditions are changed. Consequently, an improvement plan is proposed, that eventually enhances overall utilization rates of resources in the bottleneck process and reduces overall production lead-time and inventory level.

오늘날 데이타방송은 멀티미디어로 구성된 다양한 콘텐츠를 사용자들에게 제공한다. 본 본문은 이러한 멀티미디어 교통정보를 데이타방송으로 제공할 때 실시간서비스의 제약요소 가운데 하나인 콘텐츠의 수신시간을 줄이기 위하여 콘텐츠를 구성하는 멀티미디어 자원을 제어하는 하나의 자원관리시스템(Resource Management System)을 제안한다. 우리는 제안된 자원관리시스템의 효율성을 검증하기 위하여 먼저 지상파 DMB(T-DMB : Terrestrial Digital Multimedia Broadcasting)에서 멀티미디어 데이타를 전송하는 MOT(Multimedia Object Transfer)프로토콜 기반의 BWS(Broadcast Web Site)데이타방송으로 교통정보를 실시간 제공하는 교통정보의 통합시스템과 저작시스템을 소개하고, 이 시스템들과 연동하여 멀티미디어 자원생성을 관리하는 자원관리시스뎀을 구현하였다. 실험을 통하여 구현된 자원관리시스템의 자원을 이용하여 저작된 콘텐츠는 수신시간이 이전보다 약 1/13 줄어들었기 때문에 실시간 데이타방송에 적합하다.
