산지경관파편화 모니터링을 위한 기초

이 연구는 산지를 이용한 산지경관 파편화 모니터링을 제안하고 실효성을 검토하여 다음의 결과를 도출하였다. 첫째, 산지경관이 최근 9년간 빠르게 파편화되고 있어서 국가적 모니터링과 관리가 시급하다. 둘째, 산지경관(GIS) 기반의 평면적 파편화 조사만으로는 중요한 생태적 변화를 확인할 수 없으므로 다양한 조사체계와의 연계가 필요하다. 셋째, 산지경관 파편화 모니터링을 환경영향평가·재해영향평가 등과 연계하여 사전예방원칙을 제도화해야 한다. This study proposed a forest landscape (patch) fragmentation monitoring framework using a cadastral forest land dataset and validated the feasibili

Evaluation of leaf rust resistance and characteristics of Korean wheats

Leaf rust is the most widespread and destructive fungal disease, and outbreaks have always caused considerable losses in wheat yields. Thus, worldwide increases in wheat production depend on the development of leaf rust-resistant wheat varieties. In this study, we evaluated the resistance of forty Korean wheat cultivars to leaf rust at the seedling stage. Only two Korean wheats, Ol and Jono

A mixture of blackberry leafand fruit extracts decreases fat deposition in HepG2 cells

More effective treatments are needed for non-alcoholic fatty liver disease (NAFLD). We hypothesized that water extracts of blackberry fruits (BF) and leaves (BL) and their combinations (BFL) reduce fat deposition in HepG2 cells and modulate shortchain fatty acids (SCFA) and fecal bacteria in vitro. HepG2 cells were treated with BF, BL, BFL1:2, and BFL1:3 for 1 h, and 0.5 mM palmitate was ad
