최근 W3C에서 개발하고 있는 차세대 웹 문서인 XML을 이용한 웹 구축이 진행중이다. 많은 문서들이 XML문서형식으로 작성이 되는데 이렇게 대량으로 생산되는 문서들을 적절히 저장하고 다시 사용자의 질의에 맞게 재가공 되어서 제공할 수 있는 저장 시스템이 필요한데, 본 논문에서는 XML문서들의 DTD에 독립적인 데이터베이스를 구축하여 XML문서의 엘리먼트 트리상에서의 항해와 구조적 질의를 수행하기 위한 데이터베이스 구축 방법과, XML XPointer를 이용한 하이퍼링킹을 수행 하기 위한 저장 프로시듀어를 제시한다.

이기종 시스템들 간의 멀티미디어 문서 교환을 목적으로 제정된 국제 표준어 SGML(Standard Generalized Markup Language)이다[1]. 이 SGML문서로 구축된 각종 파일이나 데이터베이스들은 온라인에 의한 정보검색에 한정되어 있다. 현재 많이 활용하는 웹(WWW)에서는 이들을 XML 문서로 변환되어야 Internet상에서 이용할 수 있다. XML(eXtensible Markup Language)은 이기종 시스템들간의 문서를 교환하고 이를 웹을 통하여 보여줄 수 있다[2]. 따라서, 본 연구에서는 SGML문서를 이용하여 SML문서 형태로 변환하는 방안을 제시하고, 이를 구현하는데 목적이 있다.

This study is a efficient management techniques of road by facility database. The purpose of road ledger investigate the property of road facility, the present condition of the location, the quality of the material of the ground and underground facility. Also, this is used to make plan for construction, and investment program of the road. To build road database, photogrammetry, ground control surveying and aerial photogrammetry must be performed. After the research of the road facility, a underground facility map and the road drawings are to be made. In this study, model area is the KUMJUNG-KU in Pusan where an industrial road is located on. There are about 7,000 signal lampes and traffic safety boards. It is possible to manage scientifical and efficient road ledger though statistical handling using facility database. In this paper, authors found the database of road facility through basic circumstances in the use of SML of ARC/INFO.

Bioremediation efforts often rely on the application of surfactants to enhance hydrocarbon bioavailability. However, synthetic surfactants can sometimes be toxic to degrading microorganisms, thus reducing the clearance rate of the pollutant. Therefore, surfactant-resistant bacteria can be an important tool for bioremediation efforts of hydrophobic pollutants, circumventing the toxicity of synthetic surfactants that often delay microbial bioremediation of these contaminants. In this study, we screened a natural surfactant-rich compartment, the estuarine surface microlayer (SML), for cultivable surfactant-resistant bacteria using selective cultures of sodium dodecyl sulfate (SDS) and cetyl trimethylammonium bromide (CTAB). Resistance to surfactants was evaluated by colony counts in solid media amended with critical micelle concentrations (CMC) of either surfactants, in comparison with non-amended controls. Selective cultures for surfactant-resistant bacteria were prepared in mineral medium also containing CMC concentrations of either CTAB or SDS. The surfactantresistant isolates obtained were tested by PCR for the Pseudomonas genus marker gacA gene and for the naphthalene-dioxygenase-encoding gene ndo. Isolates were also screened for biosurfactant production by the atomized oil assay. A high proportion of culturable bacterioneuston was tolerant to CMC concentrations of SDS or CTAB. The gacA-targeted PCR revealed that 64% of the isolates were Pseudomonads. Biosurfactant production in solid medium was detected in 9.4% of tested isolates, all affiliated with genus Pseudomonas. This study shows that the SML is a potential source of surfactant-resistant and biosurfactant-producing bacteria in which Pseudomonads emerge as a relevant group.

This paper presents a SFF(shape from focus) algorithm using a new focus measure based on higher order statistics for the exact depth estimation. Since conventional SFF-based 3D depth reconstruction algorithms used SML(sum of modified Laplacian) as the focus measure, their performance is strongly depended on the image characteristics. These are efficient only for the rich texture and well focused images. Therefore, this paper adopts a new focus measure using HOS(higher order statistics), in order to extract the focus value for relatively poor texture and focused images. The initial best focus area map is generated by the measure. Thereafter, the area refinement, thinning, and corner detection methods are successively applied for the extraction of the locally best focus points. Finally, a 3D model from the carefully selected points is reconstructed by Delaunay triangulation.

Melt textured YBCO superconductors were fabricated by the top seeding method using Sml.8($Sm_{1.8}$ $Ba_{2.4}$ $Cu_{3.4}$$O_{7-Y}$) seed. We investigated the twin structures using the optical microscope, SEM and TEM. The twin structures formed during the tetragonal to orthorhombic transition which occurred at $450^{\circ}C$ in sample oxygen annealing. The twin structures were clearly observed by SEM due to the chemical etching effects. The lengths of twin structures were increased as the oxygenation heat treatment time increased from 1hr to 10hr. We investigated twin structure by TEM. The twin spaces were considered to be related to the oxygen contents. The results suggested an oxygen diffusion model for the formation of the twin lengths.

A new model management framework is proposed to accommodate wide-spreading algebraic modeling languages (AMLs), and to facilitate a full range of model manipulation functions. To incorporate different modeling conventions of the leading AMLs (AMPL, GAMS, and SML) homogeneously, generic model concepts are introduced as a conceptual basis and are embodied by the structural and operational constructs of an Object-Oriented Database Management System(ODBMS), enabling the framework to consolidate components of DSSs(database, modelbase, and associated solvers) in a single formalism effectively. Empowered by a database query language, the new model management framework can provide uniform model management commands to models represented in different AMLs, and effectively facilitate integration of the DSS components. A prototype system of the framework has been developed on a commercial ODBMS, ObjectStore, and a C++ programming language.

최근 인터넷과 무선통신기술의 융합으로 인한 Mobile 서비스의 급격한 발전으로 인해 무선 인터넷 시장이 도입 및 성장단계에 이르렀다. 그러나 현재 무선 인터넷 환경은 음성 서비스 위주의 개인사용자 시장이 한계에 도달하면서 이동통신의 무선단말기를 통해 다양한 비즈니스를 벌일 수 있는 기업용 모바일 솔루션 시장이 크게 확대되고 있고 모바일데이터서비스 시장의 비중이 크게 늘어가고 있다. 이러한 데이터서비스 교환에 XML문서를 사용한다면 데이터의 상호 처리 능력을 향상시키고 데이터의 공용성과 프로그램의 유연성을 향상시키는데 필요한 비용과 노력을 훨씬 절감할 수 있다. 본 논문에서 제안된 시스템 설계를 통해 XML 문서를 데이터 교환에 사용하여 무선 장치의 CPU, 메모리, 네트워크 대역폭의 부하를 줄임으로써 무선 인터넷에서 보다 빠르고 효율적으로 문서를 주고받을 수 있도록 구현하였다.
