Small hydropower is one of the many types of new and renewable energy, which is planning to develop, as the country is abundant in endowed resources. In order to fully utilize small hydropower resources, there is a need for greater precision in quantifying small hydropower resources and establish an environment in which energy sources can be discovered using the small hydropower resource management system. This study has given greater precision to calculate annual electricity generation and capacity of small hydropower plants of Nakdong river system by inquiring into average annual rainfall, basin area and runoff coefficient, which is anticipated to promote small hydropower resources utilization. Small hydropower resource management system was also established by additionally providing base information on quantified small hydropower resources and analysis function and small hydropower generator status, rivers, basin, rainfall gauging station, water level gauging station etc.. Small hydropower resource management system can be used gather basic information for positive applications of small hydropower energy nationwide.

Recently, many companies knock themselves out to reduce logistics costs. However, they have reached the limit on cost reducing by improving the manufacturing process. In addition, Customers are growing more and more particular about the quality. Also the firms, which provide foods & beverages manufacturer with vacant receptacles and bottles, make zealous efforts to save costs. They have tried to seek for the resolution by own investment and improving system, but they haven't found certainly substitutions. In this study, we analyze problems of the vacant receptacles manufacturers and present introduction of pool system by standardization of Packing Resource. This PPS(Packing resource Pool System) will enable to reduce logistics cost that is challenge for the receptacles & bottles manufacturers, be helpful reducing environmental disruption which are the pollution of alien substances, wasted paper sheets because the system cleans retrieved Packing resources and reuses them.

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 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 wast geverated 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.

최근의 프로그램들은 그림 파일이나 오디오와 같은 대용량의 자원을 사용하는 경향이 있다. 이와 같은 대용량 자원을 사용하는 경우 그 자원의 크기가 클수록 자동 관리 시의 효율성이 더 많이 저하되며, 자원의 수가 많을수록 관리의 어려움이 증가된다. 이에 본 논문은 파일시스템의 트리 구조의 인터페이스를 자원관리 시스템에 적용하여 편의성과 효율성을 도모한 자원관리시스템을 제안한다. 이 시스템은 문자열경로 기반의 접근방식을 채택하여 높은 호환성을 가지고 있으며, 트리 구조 지원으로 높은 구조성을 도모하고, 가상 노드의 지원으로 높은 효율성을 보인다. 본 시스템은 프로세스 안에서의 자원 관리를 위해 설계되었으나, 프로세스 외부로부터의 자원제어도 지원한다.

The architecture of the CDMA mobile system (CMS) is developed based on three function groups - service resource, service control, and service management groups. In this paper, the CMS architecture is discussed from the point of view of implementing these functions. The variable length packets are used for transmission. The synchronization clock signals are derived form the GPS receiver. The open loop and closed loop techniques are used for the power control. The internationally accepted signaling and network protocols are employed. The call control for the primary services in designed to provide efficient mobile telecommunication services. The softer handoff is implemented in one card. The mobile assisted handoff and the network assisted handoff are employed in the soft and hard handoffs. The authentication is based on the secret data which includes random numbers. The management functions, which include the location management, resource management, cell boundary management and OAM management, are implemented to warrant the system efficiency, maximum capacity and high reliability. The architecture ensures that the CMS is flexible and expandable to provide subscribers with economic and efficient system configuration. The dynamic power control, adaptive channel allocation. and dynamic cell boundary management are recommended for future work.

Cloud computing integrates computing resources such as servers, storage, and networks with virtualization technology to provide suitable services according to user needs. Due to the structural characteristics of sharing physical resources based on virtualization technology, threats to availability can occur, so it is essential to respond to availability threats in cloud computing. Existing over-provisioning method is not suitable because it can generate idle resources and cause under-provisioning to degrade or disconnect service. System resources must be allocated in real-time according to the system load to guarantee the cloud system's availability. Through appropriate management measures, it is necessary to reduce the system load and increase the performance of the system. This paper analyzes the work response time according to the allocation or migration of virtual machines and discusses an efficient resource management method considering the system load.

방재자원은 재난 발생시 투입하는 인력, 물자, 장비, 시설 자원을 의미한다. 물자, 장비 자원은 평상시 내부적으로 관리되는 자원으로 신속하고, 적합한 자원을 투입하여 재난을 최소화하여야 한다. 그렇지만 현재 방재자원 관리는 시군구의 재난관리시스템과 중앙의 재난관리시스템으로 이원화되어 있으며, 정보의 갱신이 실시간으로 되어있지 않아서 적시에 적합한 자원을 투입하기에 어려운 상태이다. 본 연구에서는 시군구에 분산된 방재차원에 대한 효과적인 관리를 통하여 가시성을 확보함으로써 적시에 적합한 자원을 투입할 수 있는 모델을 제시하고 있다. 특히 적합한 자원을 신속하게 파악할 수 있게 방재자원을 분류하고, RFID 표준에 기반한 방재자원의 ID와 메타데이터 정보를 제시하고, 이를 기반으로 실시간으로 방재 차원을 관리할 수 있는 모텔을 제시하였다.

The cloud computing is technology which gives flexible and solid infrastructure to IT environment. With this technology multiple computing environment can be consolidated in to a single server so that maximize system resource utilization. Better processing power can be achieved with less system resource. IT manager can cope with increasing unnecessary cost for additional server and management cost as well. This means a enterprise is able to provide services with better quality and create new services with surplus resource. The time required for recovery from system failure will be reduced from days to minutes. Enhanced availability and continuity of enterprise business minimize the codt and the risk produced by service discontinuity. In this paper, we propose framework architecture that is strong against denial-of-service attack.

In the era of the 4th industrial revolution, the aviation industry is also growing remarkably with the development of artificial intelligence and networks, so it is necessary to study a new concept of crew resource management (CRM), which is required in the process of operating state-of-the-art equipment. The automation system, which has been treated only as a tool, is changing its role as a decision-making agent with the development of artificial intelligence, and it is necessary to set clear standards for the role and responsibility in the safety-critical field. We present a new perspective on the automation system in the CRM program through the understanding of the autonomous system. In the future, autonomous system will develop as an agent for human pilots to cooperate, and accordingly, changes in role division and reorganization of regulations are required.
