An Integrated Data Environment (IDE) is the end state of the CALS vision. It refers to an environment where all the data generated from the entire lifecycle activities of a product can be shared by anyone that participates in the management. engineering, manufacturing, or support of the product, although the data are geographically distributed and are maintained in heterogeneous platforms. The primary purpose of this paper is to introduce the fundamental concept, architecture, and core implementation technology of an IDE. The secondary purpose is to suggest some strategic directions to the planning staffs in both government and industry. and to suggest some research issues to the researchers in academia. The reference architecture of an IDE being developed by the US DoD and that of NIIIP (National Industrial Information Infrastructure Protocol) being developed by a consortium are discussed. Two principal issues of implementing an integrated database, i.e., distributed object computing including CORBA and multi-database system (MDBS) are reviewed. As a conclusion. the author suggests that daring investment in prototyping an IDE by a nationwide consortium is essential to keep up with the advanced countries in CALS implementation.

A bacterial consortium capable of utilizing a variety of polycyclic aromatic hydrocarbons has been isolated from a former manufactured gas plant site. The consortium consisted of four members including Arthrobacter sp., Burkholderia sp., Ochrobacterium sp., and Alcaligenes sp., which were identified and characterized by the patterns of fatty acid methyl esters (FAME analysis) and carbon source utilization (BIOLOG system). With the individual members, the biodegradation characteristics of aromatic hydrocarbons depending on different growth substrates were determined. FAME analyses demonstrated that microbial fatty acid profiles changed to significant extents in response to different carbon sources, and hence, such shift profiles may be informative to characterize the biodegradation potential of a bacterium or microbial community.

As the International Human Epigenome Consortium (IHEC) launched officially at the 2010 Washington meeting, a giant step toward the conquest of unexplored regions of the human genome has begun. IHEC aims at the production of 1,000 reference epigenomes to the international scientific community for next 7-10 years. Seven member institutions, including South Korea, Korea National Institute of Health (KNIH), will produce 25-200 reference epigenomes individually, and the produced data will be publically available by using a data center. Epigenome data will cover from whole genome bisulfite sequencing, histone modification, and chromatin access information to miRNA-seq. The final goal of IHEC is the production of reference maps of human epigenomes for key cellular status relevant to health and disease.

This study examined the capacity of immobilized bacteria to degrade petroleum hydrocarbons. A mixture of hydrocarbon-degrading bacterial strains was immobilized in alginate and incubated in crude oil-contaminated artificial seawater (ASW). Analysis of hydrocarbon residues following a 30-day incubation period demonstrated that the biodegradation capacity of the microorganisms was not compromised by the immobilization. Removal of n-alkanes was similar in immobilized cells and control cells. To test reusability, the immobilized bacteria were incubated for sequential increments of 30 days. No decline in biodegradation capacity of the immobilized consortium of bacterial cells was noted over its repeated use. We conclude that immobilized hydrocarbon-degrading bacteria represent a promising application in the bioremediation of hydrocarbon-contaminated areas.

One of the problems associated with the current system of land development projects implemented by the public sector in Korea is that various service facilities are not ready in time for the occupation of residential dwelling. A major cause of the problem is the lack of financial arrangements which would smooth the cash-flow of the suppliers of the facilities during the project period. In this paper we present two schemes which will contribute to the optimal provision of service facilities by easing the financial constraint facing the land developers and suppliers of the facilities. The first scheme involves channeling a fraction of profits from a land development project and of the proceeds of mandatory sales of Type II National Housing Bonds as a loan to the suppliers of the service facilities. The second scheme considers the participation of the private sector in the project as a member of a consortium comprising the Korea Land development Corporation, the National Housing Fund, and private developers. It is proved that each scheme is superior to the current system. as well as entailing a very small cost.

In this study, the treatment ability of the wastewater containing perchlorate by non-salt tolerant perchlorate reducing bacterial consortium (N-PRBC) was evaluated in a continuous stirred tank bioreactor (CSTR). To obtain the optimal operating condition the bioreactor was operated with the different wastewater empty bed retention time (EBRT). The treatment performance in the bioreactor could be maintained at 100 $mg-ClO_4{^-}L^{-1}$ up to a EBRT of 3 h, and the removal capacity in the CSTR was about 3.3 times higher than that in a batch operation. With a decrease from 9 h to 2 h in a EBRT, the volumetric perchlorate reduction rate was increased from 11.1 $mg-ClO_4{^-}L^{-1}h^{-1}$ to 50.0 $mg-ClO_4{^-}L^{-1}h^{-1}$, and the specific perchlorate reduction rates were increased from 3.01 $mg-ClO_4{^-}g-DCW^{-1}h^{-1}$. In conclusion, the treatment capacities in a CSTR were much better than those obtained in a batch operation.

GML(Geography Markup Language)은 XML(extensible Markup Language)의 장점을 이용하여 지리 데이터의 저장과 전송을 위해 OGC(Open GIS Consortium)에서 제안되었다 이러한 GML은 웹 환경의 발전에 따라 지리 정보 통합을 위해 널리 이용되고 있으나. GML 문서에 대한 지리 데이터 검색 기술은 미흡하다. 최근 W3C(World Wide Web Consortium)에서는 XML 문서로부터 데이터를 추출하기 위한 표준 질의어로 XQuery를 추천하기 위한 작업 초안(working draft) 상태에 있다. 그러나 이러한 XML 질의어는 지리 정보의 추출에 대한 고려는 하고 있지 않다. 따라서 본 논문에서는 지리 정보를 포함하고 있는 GML 문서를 기반으로 지리 정보를 검색. 추출할 수 있는 GML Query language인 GQuery를 제안하고자 한다. 본 논문의 GQuery는 서로 이질적인 공간 데이터베이스의 데이터를 통할하여. 통합된 문서내의 지리정보를 추출하기 위한 사용자 인터페이스로 이용할 수 있다.

단행본, 소설, 잡지, 만화 등 다양한 형태의 전자출판물에 공통적으로 적용 가능한 표현 기술과 콘텐츠 유통을 위한 패키징 기술로 구성된 표준인EPUB3가 국제표준기구인 ISO/IEC에서 국제표준으로 채택됨에 따라 시장 표준이 공적 표준으로 통합되는 현상이 전자출판 분야에서도 뚜렷이 나타나고 있다. 본고에서는 전자출판 표준인 EPUB3을 교과서 등 교육용 교재, 참고서, 학습서 등 교육 분야에 확대 적용하기 위하여 온라인 평가 서비스, 학습용 소프트웨어 연계, 교육용 메타데이터 활용 등 이질적인 기술 들 간의 융합이 어떻게 이루어져야 하는지에 대한 방향을 제시한다. 이러한 노력은 지난 2013년부터 국제 표준화 단체인 IDPF(International Digital Publishing Forum), IMS Global Learning Consortium, World Wide Web Consortium이 구성한 EDUPUB Alliance를 통해 구체화되고 있다. 따라서 향후 어떠한 구체적인 주제의 논의가 국내에서도 필요한지 알아본다. 또한 디지털 교과서와 학습 교재는 모바일 및 온라인 학습환경에서 다양하게 활용될 수 있으며, 학습자가 생성하는 학습 데이터를 체계적으로 수집하고 분석한다면 학습결과를 향상시키는데 큰 기여를 할 수 있을 것으로 기대한다.

Recently, loosely-coupled systems are widely used for distributed computing environment. We develop a web GIS server who conforms to the international standards developed by the Open GIS Consortium (OGC), such as web feature service (WFS) implementation specification, Geography Markup Language (GML) implementation specification, and the simple features specification for OLE/COM. The web GIS server provides interoperable access of spatial data among data formats in the distributed environment.

Forest fire monitoring prototype system was developed by National Development Agency of Japan (NASDA) and the Ministry of Agriculture, Forestry and Fisheries of Japan (MAFF) to verify the usefulness of interoperabile system to study new services of Earth observation satellite data distribution for a practical application. In this system, a standard interface of Web based GIS technology, OpenGIS Consortium (OGC) technology, was adopted. This system is also expected to encourage data sharing activities in Digital Asia Network (DAN) as a demonstration system.
