Effective management of unique animal genetic resources, such as local breeds, is one of the most important concerns in modern breeding. In the present study, 30 microsatellite loci were analyzed to evaluate the genetic diversity, population structure, and relationships among Jeju native and exotic pig breeds. In total, 200 animals from four pig breeds (Jeju native, Landrace, Yorkshire and Berkshire) were analyzed, 50 individuals per breed. Overall, 265 alleles were observed. The mean expected and observed heterozygosity (HExp and HObs) and polymorphism information content (PIC) of Jeju native pig were calculated at 0.550, 0.565, and 0.485, respectively. However, exotic breeds were higher level of these diversity parameters than those of Jeju native pig. Phylogenetic analysis, factorial component analysis (FCA), and genetic clustering results showed a clear distinction among the four groups representing the breeds, supporting the genetic uniqueness of the Jeju native breed in comparison with Western commercial breeds. These results were scientific evidence that Jeju native pig represent a unique and valuable animal genetic resource.
블루 안료 15 : 6이라 불리는 e결정상의 동프탈로시아닌(e-CuPc)는 LCD 패널에서 청색화소를 제공하는 중요한 소재로써, 본 연구에서는 e-CuPc 시료를 e-CuPc 나노 입자를 seed로 이용하는 방법으로 여러 조건에서 합성하여 적합한 용매 및 온도조건 등을 규명하였고, 이를 미리 합성한 α 및 β 결정상의 CuPc 시료들과 비교함으로써 e-CuPc 시료의 결정상, 결정 순도, 합성 수율 및 미세구조를 상호 비교·분석하였다. 시료들의 화학 구조 및 결정 구조는 푸레어 변환적외선(FT-IR) 분광기 및 X선 회절 분석기(XRD)를 이용하여 각각 비교 분석하였다. 또한, 입자의 형상 및 크기는 주사 전자현미경(FE-SEM)으로 비교 분석하였고, 열적 특성은 열중량분석기(TGA)를 이용하여 비교 분석하였다.
