  • The purpose of this paper is to design Conformance Test Suite for BSP(Biometric Service Provider) based on BioAPI(Biometric Application Programming Interface) v2.0. The proposed BioAPI Conformance Test Suite enables users to test BSP with framework independently. A test scheduling tool has been embodied to use Test Assertion in the form of XML. In order to demonstrate the performance of the Conformance Test Suite, the experiment was performed by using both verification and identification BSPs. As the results of this experiment, we were able to determinate whether BSPs based on BioAPI v2.0 satisfied standard requirements or not.

  • 분산 환경에서 신분 확인을 위한 생체인증기기가 이용되는 경우 그 기기가 생체인증 표준인 BioAPI를 준용하여 제대로 구현된 것인가에 대한 적합성 시험이 필요하게 된다. 이러한 적합성 시험은 분산 환경의 사용자 및 서비스 제공자에게 표준 규격을 준용한 제품이라는 신뢰성을 주게 된다. 기존에 제공되는 있는 BioAPI(Biometric Application Programming Interface) v2.0 기반의 BSP(Biometric Service Provider)는 오프라인 상에서 BioAPI기반의 제품의 준용 여부만을 평가하기 때문에 분산 환경에서 여러 사람이 동시에 준용 여부를 평가 받기 힘들며 이에 따른 동시 서비스 제공도 불가능하다. 본 논문에서는 BioAPI v2.0 기반의 제품들이 분산 환경에서 제공되는 9개 모델의 표준화된 환경으로 구분하고, 원활한 적합성 시험을 위하여 XML기반의 Test Assertion을 설계하여 생체인증 API 표준 적합성을 시험하였다. XML Test Assertion을 이용한 생체인증 적합성 시험을 위한 메시지 플로우를 밝혀 그 타당성을 입증하였다.

  • Powdery mildew is one of the most devastating diseases in cucurbits. Crop yield can decline as the disease severity increases. In this study, we evaluated the effect of silver nanoparticles against powdery mildew under different cultivation conditions in vitro and in vivo. Silver nanoparticles (WA-CV-WA13B) at various concentrations were applied before and after disease outbreak in plants to determine antifungal activities. In the field tests, the application of 100 ppm silver nanoparticles showed the highest inhibition rate for both before and after the outbreak of disease on cucumbers and pumpkins. Also, the application of 100 ppm silver nanoparticles showed maximum inhibition for the growth of fungal hyphae and conidial germination in in vivo tests. Scanning electron microscope results indicated that the silver nanoparticles caused detrimental effects on both mycelial growth and conidial germination.

  • A very rapid and efficient separation technique for cellular rhizobial cyclosophoraoses was developed based on fractional precipitation and partition chromatography. Cyclosophoraoses are known to function in the osmotic regulation and root nodule formation of legumes during the nitrogen fixation process. Cyclosophoraoses are produced as unbranched cyclic (1longrightarrow12)-${\beta}$-D-glucans in Agrobacterium or Rhizobium species. Recent research has shown that cyclosophoraoses can form inclusion complexation with various unstable or insoluble guest chemicals, thereby implying great potential for industrial application. Typical separation of pure cellular cyclosophoraoses has been so far carried out by several time-consuming steps, including size exclusion, anion exchange, and desalting liquid chromatographies, with a relatively poor recovery. However, the proposed method demonstrated that the successive application of fractional ethanol precipitation and one step of silica gel-based flash column chromatography was enough to simultaneously purify neutral or anionic forms of cyclosophoraoses. This novel technique is very rapid and provides a high recovery.
