현재 차세대 인터넷 웹 표준으로 자리잡은 XML(eXtensible Markup Language)을 근간으로 하는 ebXML(electronic business XML)은 국가내 전자상거래의 거래뿐만 아니라 국가와 국가간의 거래에도 적용될 수 있는 표준으로 확정되어 주목받고 있다. 이에 본 논문에서는 ebXML Solution 개발시 핵심부분이 될 Registry와 Repository 에 관한 일반적인 프레임워크 설계안을 제시하고자 한다.

B2B 물류솔루션이 표준에 기반하지 않은 독자적인 방식으로 개발되었을 때 기업간 협업 및 상호운용성에 많은 어려움이 존재하게 된다. 이 경우 XML 기반의 국제 표준 프레임워크인 ebXML을 적용하여 기업간 협업 문제를 해결할 수 있다. 본 연구에서는 ebXML 기반의 물류 협업 서비스 구축기반을 제공하기 위해 필요한 물류협업정보 등록저장소를 정의하고, 시스템을 설계 및 구현하였다. 또한 물류라는 특정 산업분야에 적용하면서 발생하는 분류(Classification) 문제와 XML문서 상의 URI 타입 속성이 등록저장소에 엔트리를 가리킬 때의 질의문제를 해결하였다.

B2B registries are information systems to registrate B2B related business information such as companies' profiles, business documents, business processes, services and to provide query facilities to find information about potential business partners. In this study, we focus on the design of the repository for B2B business processes. In this paper, a metadata ontology is designed to registrate B2B business processes. In practice, there are several competitive business process definition languages such as ebXML BPSS (Business Process Specification Schema), WSBPEL (Web Service Business Process Execution Language), BPMN (Business Process Modeling Notation), and so on. In order to registrate business processes based on different representation frameworks, the proposed metadata ontology consist of three layers, common metadata, language-specific metadata, and interrelationship metadata. To implement the proposed metadata ontology using ebXML registry, metadata mapping scheme to ebRIM (ebXML Registry Information Model) are also suggested.

XML을 이용하여 인터넷 기반의 B2B e-business가 가능하도록 하는 전자상거래 국제 표준안인 ebXML이 국제 기구인 UN/CEFACT와 OASIS가 공동 추진하여 지난 5월 표준으로 제정되었다. ebXML의 핵심은 등록기/저장소이며 등록기/저장소에서 지원하는 등록기 서비스에는 객체 관리 서비스와 객체 질의 관리 서비스가 존재한다. 본 논문에서는 현재 제안된 표준 vl.0을 기준으로 등록기에 저장된 메타데이타를 검색할 수 있는 서비스 인터페이스를 정의하고, 이를 위한 질의를 제공하는 객체 질의 관리 시스템을 설계 및 구현하였다. 또한 Browse & Drilldown Query, Filter Query와 같은 ad-hoc 질의 서비스를 제안하였다.

In this study, effect of EB-PVD coated Si/HA film thickness on surface characteristics of Ti-35Nb-10Zr alloy was investigated. The Ti-35Nb-10Zr alloy was fabricated by arc melting method. The Si/HA layers were coated with 0.8 wt.% of Si in pure HA by EB-PVD method. The coating thickness was consisted with 100 - 300 nm for each group, the surface characteristics was analyzed by FE-SEM, EDS, XRD, XRF and corrosion test. The Si/HA coating layer was well deposited on the alloy surface by EB-PVD, the thickness was correlative factor with HA peaks and corrosion resistance value.

기업간 전자상거래를 위한 국제표준인 ebXML 은 ebBPSS(ebXML Business Process Specification Schema)와 CPA(Collaboration Protocol Profile)에 기반하여 거래 당사자들이 협업 형태의 업무 처리 절차에 따라 문서 및 데이터를 주고 받을 수 있도록 해 준다. 거래 당사자들의 내부 업무처리 시스템에 연동되어 B2B 업무를 처리할 수 있도록 해주는 시스템을 BSI(Business Service Interface)라 하며, 이는 트랜잭션 관리, 업무 프로세스의 코레오그래피(Choreography), 문서 관리, 보안 관리 등 협업과 관련된 대부분의 역할을 수행하게 된다. 기업간 협업에 있어 가장 중요한 사항 중 하나는 어떤 상황에서도 양쪽의 협업상태 정보는 일관성을 유지해야 한다는 것이다. 이는 거래의 신뢰도를 확보하기 위한 필수사항이라 할 수 있다. 본 논문에서는 ebXML 프로토콜에 따라 거래행위시 협업상태 정보가 양측 거래파트너에서 각기 다르게 나타날 수 있는 상황을 살펴 보고 이에 따른 BSI 시스템의 대처방안에 대해 살펴보고자 한다.

In order to develop a new microbial fungicide for the control of vegetable diseases using endophytic bacteria, a total of 260 bacterial strains were isolated from fresh tissues of 5 plant species. After they were cultured in broth media, their antifungal activities were screened by in vivo bioassays against Botrytis cinerea(tomato gray mold), Pythium ultimum(cucumber damping-off), Phytopkhora infestans(tomato late blight), Colletotrichum orbiculare(cucumber anthracnose), and Blumeria graminis f. sp. hordei(barley powdery mildew). As the results of screening, 38 bacterial strains showed potent antifungal activities against at least one of 5 plant pathogens. A bacterial strain EB072 displayed potent disease control activities against 3 plant diseases. Among the bacterial strains with a potent antifungal activity against cucunlber anthracnose, three bacterial strains, EB054, EB151 and EB215, also displayed a potent in vitro antifungal activity against C. acutatum, a fungal agent causing pepper anthracnose. A bacterial strain EB215 obtained from roots of cucumber was identified as Burkholderia cepacia based on its physiological and biochemical characteristics and 165 rRNA gene sequence. An antifungal substance was isolated from the liquid cultures of B. cepacia EB215 strain by ethyl acetate partitioning, repeated silica gel column chromatography, and invitro bioassay, Its structural determination is in progress by various instrumental analyses.

Direct communication between neighboring cells through connexin (Cx)-based gap junction is a crucial biological manner to regulate functions of a tissue consisting of multi-cell types. The present research evaluated expressional changes of Cx isoforms in the caput epididymis of adult rat exposed to estradiol benzoate (EB) or flutamide (Flu) at the early postnatal age. A single subcutaneous administration of EB at a low-dose [$0.015{\mu}g/kg$ body weight (BW)] or a high-dose ($1.5{\mu}g/kg\;BW$) or Flu at a low-dose ($500{\mu}g/kg\;BW$) or a high-dose (5 mg/kg BW) was performed to an animal at 1 week of age. Quantitative real-time PCR analysis was employed to determine expressional changes of Cx isoforms. The transcript levels of Cxs30.3 and 37 were decreased by a low-dose EB treatment, while decreases of Cxs31, 31.1, 32, 40, and 45 transcript levels were observed with a low-dose EB treatment. The treatment of a high-dose EB resulted in expressional reduction of Cxs30.3, 31, 31.1, 37, 40, 43, and 45. The Flu treatment at a low dose caused increases of Cxs26, 37, and 40 transcript levels but decreases of Cxs31.1, 43, and 45 transcript levels. Increases of Cxs30.3, 31, 37, and 40 mRNA amounts were induced by a high-dose Flu treatment. However, exposure to a high-dose Flu produced expressional decreases of Cxs31.1, 32, and 43 in the adult caput epididymis. These observations suggest that exposure to EB or Flu at the neonatal period could lead to aberrant expression of Cx isoforms in the adult caput epididymis.
