대한수의학회 Journal of Veterinary Science 2017, 제 18권 제 2호 11 209-216 (8 pages)
The efficacies of six commercial disinfectants were evaluated by using Salmonella enterica serovar Typhimurium under simulated natural conditions such as sub-zero temperature, short disinfecting time, and surface type (uneven or smooth). We used a suspensionmodel test to determine the disinfecting efficacy under varying contact times (1, 5, 10, and 30 min) and temperatures (25°C, 4°C, 0°C, and -10°C). The bactericidal effect according to surface structure was measured by using a carriermodel... -

The aim of this study was to demonstrate and assess C-reactive protein (CRP) changes in dogs with induced bacterial cystitis with or without antibiotics. We also evaluated availability of CRP levels to serve as an indicator for monitoring or diagnosing bacterial cystitis. Serial CRP concentrations in dogs with induced bacterial cystitis were higher than those of controls (p ＜ 0.001). CRP concentrations peaked on day 7 and gradually decreased thereafter. In the treatment group, CRP... -

The short-term effects of low-level contamination by heavy metals (As, Cd, Cu, and Pb) on the soil health were examined by analyzing soil nematode community in soils planted with tomatoes. For this, the soils were irrigated with five metal concentrations ([1, 1/4, 1/4, 1/4, and 0] × maximum concentrations [MC] detected in irrigation waters near abandoned mine sites) for 18 weeks. Heavy metal concentrations were significantly increased in soils irrigated with MC of heavy metals, among... -
Genetic Variability and Geographical Distribution of Mycotoxigenic Fusarium verticillioides Strains Isolated from Maize Fields in Texas
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2015, 31권 3호 1 203-211 (9 pages)
Maize is the dominant cereal crop produced in the US. One of the main fungal pathogens of maize is Fusarium verticillioides, the causative agent of ear and stalk rots. Significantly, the fungus produces a group of mycotoxins - fumonisins - on infested kernels, which have been linked to various illnesses in humans and animals. Nonetheless, durable resistance against F. verticillioides in maize is not currently available. In Texas, over 2.1 million acres of maize are vulnerable to fumonisin... -

배출량이 급격히 증가하였고, 질적으로 다양화 되고 있다. 국내 폐기물 처 리정책의 주요내용은 자원을 효율적으로 이용 함으로써 자연으로부터의 자원채취를 최소화 함과 동시에 자연으로 되돌려지는 폐기물을 최소화함으로써 자연환경을 보호하고 사람의 건강을 보존하는 것이다. 선·후진국을 막론 하고 폐기물관리정책의 변화과정은 비슷하다. 초기에는 단순히 “폐기물”을 처리하는 “청 소(Cleaning)개념”에서 시작하여 “재활용 (Recycle)" 문제로 정책중심이 이동하였으며, 최근에는 “폐기물 최소화(Waste Minimization) 및... -
