Lately, most of the libraries subscribe electronic resources such as e-journals, under the license contracts for the access and use of these electronic resources. It was found that the management of licensed electronic resources in the library has become one of the major problems due to the lack of proper metadata elements in the existing management system of electronic resources. The purpose of the study is to establish metadata for licensed electronic resources.

Increasing the value of data, paradigm shifts in research methods, and specific manifestations of open science indicate that research is no longer text-centric, but data-driven. In this study, we analyzed the services for DCC, ICPSR, ANDS and DataONE to derive key elements and functional requirements for research data management and services that are still insufficient in domestic research. Key factors derived include DMP writing support, data description, data storage, data sharing and access, data citations, and data management training. In addition, by presenting functional requirements to the derived key elements, this study can be applied to construct and operate RDM service in the future.

최근 농림부에서는 축산물 위생 및 안전성을 확보하기 위하여 도축장, 우유 ${\cdot}$ 육가공장, 배합사료공장에 이어 사육단계에서도 HACCP(위해요소중점관리제도)도입을 단계적으로 추진하겠다고 발표한 바 있다. 특히 사육농장에서 안전한 축산물을 생산하는데 해로운 영향을 미칠 수 있는 각종 위해요소를 파악, 이를 사전에 차단하거나 중점 관리하는 사육단계의 HACCP를 2006년 돼지농장을 시작으로 2007년 젖소, 2008년 한육우, 2009년 산란계, 2010년 육계공장까지 단계적으로 확대 도입할 계획이다. 따라서 본 고에서는 최근 일본에서 제정한 가축의 생산단계인 농장에서의 위생관리지침서의 주요 내용을 소개하고자 한다

최근 웹서비스의 사용은 응용 칸 통신과 상호운용성의 필요가 증가됨에 따라 빠르게 확장되고 있다. 웹 서비스는 SOA의 참조아키텍처로서 필요한 복잡한 연산 수행 컴포넌트를 표준인터페이스를 사용하여 결합하도록 한다. 그러나 웹서비스에 대한 분산 기업응용에 적용이 요구되고 있으며 이를 위해 위험요소분석, 대응정책 및 해결책에 대한 방안이 부재한 상태이다. 본 논문에서는 다양한 웹서비스의 품질관리를 위한 지능형 웹 서비스 품질 관리 아키텍처를 설계하고 웹서비스의 관리를 위해 온톨로지를 적용하여 운영할 수 있는 아키텍처를 제안한다.

본 논문에서는 현재 표준화 진행중인 디지털 저작권 관리 시스템의 다양한 기술들을 살펴본다. 저작권 관리 시스템을 구성하는 요소로 암호화, 접속 제한, 복사 제어, 신원 확인 등이 있으며 이러한 요소를 이루는 기술로 최근 워터마크의 연구가 활발히 진행중이다. 워터마크 기술은 응용 범위가 넓고 잠재적 개발 가능성이 크지만 아직까지 분명한 한계가 있으며, 강인성과 품질 사이에 요구사항이 서로 트레이드오프 상태에 있는 단점이 있다. 따라서 저작권 관리 시스템의 구현을 위해서는 먼저 시스템의 요구사항을 분명히 규정하고, 그것에 적합한 기술을 최적화하는 것이 필요하다.

현대 도서관은 전자자원(electronic resource)의 양적인 급증으로 인하여, 전통적인 수서정책이나 관리시스템만으로 효과적인 관리가 점차 어려워지고 있다. 이러한 문제를 해결하기 위해 도서관들은 전자자원 관리에 대한 시스템적인 이론과 알고리즘을 개발하고 있다. 이 점에 착안하여 이 연구에서는 급증하고 있는 전자자원의 효율적 관리와 활용을 위한 필수 전자자원 관리용 메타데이터의 제안과 이를 이용한 효율적 관리방안을 제안하였다. 이 연구의 결과로 도출된 전자자원 관리용 메타데이터의 요소들은 향후 전자자원 관리시스템 개발에 있어서 기초자료로 활용될 것이다.

In a heterogeneous wireless environment, a variety of Radio Access Technologies (RATs) coexist. Since the number of RATs is anticipated to increase in the near future, it is desirable to have radio and network resources managed in a cooperative manner using the Common Radio Resource Management (CRRM) strategy. In order to make RAT-specific radio resources manageable in CRRM, this paper proposes the Analytical Network Process (ANP) based resource management scheme that efficiently allocates resources among heterogeneous wireless networks. The proposed ANP-based method is flexible enough to be used in any network environment and can consider a multitude of decision factors. In addition, the proposed scheme uses a radio bandwidth model, which properly reflects transmission rates under given channel conditions, as the actual radio resources to be allocated. The model considers the AMC (Adaptive Modulation and Coding) scheme that is widely used in current broadband wireless access technologies, and thus, packet service characteristics, such as response time, can be analyzed. The effectiveness and flexibility of the proposed method are demonstrated by implementing a number of existing factors on heterogeneous networks environment.

This study is aimed to develop standard metadata model and develop elements and present the importance of oral history archives that contrast with literature history. The study analyzed standard metadata description elements that can express contents and forms of oral history archives as information. Furthermore, it designed Project, Management, Record, and metadata modeling as a Related record domain for the sake of building digital oral archives. Finally, the study gave shape to real oral history archives based on basic elements, details, and design principles of division elements.

The safety of industrial valves, which are the core parts of plant facilities, are managed by manpower and there are difficulties because of side area for inspection and limited accessibility due to the nature of facilities. The industrial valves used in plant facilities cause problems such as interrupted production; a loss of life due to leak or explosion of poisonous material and flammable gases, and difficulty in locating accident positions in the event of leakage or failure. Therefore, safety management and control systems based on IoT technology are needed. This study is about the development of risk factor prediction technique among the safety management of industrial valves through IoT- based wireless communication and the development of actuator control system. We have developed IoT-based industrial valve safety management techniques to prevent accidents caused by main risk factors by conducting an analysis of the structural characteristics of valves and an analysis of the causes of main risk factors through review of failure data and literature and an analysis of accident scenarios.

Among the various factors influencing construction productivity, weather conditions or elements become very important factors in planning and executing construction project. It is especially true in Korea where the weather changes dramatically through few seasons. In this study, relationship between construction productivity of the reinforced concrete structure we for the high-rise apartment buildings and 5 weather elements including temperature, humidity, day time, rainfall, and wind velocity have been analyzed The results trough regression analysis showed that weather elements explain $58.8\%$ of productivity in total and temperature and day time were more important factors among them.
