BGRcast: A Disease Forecast Model to Support Decision-making for Chemical Sprays to Control Bacterial Grain Rot of Rice
한국식물병리학회 The Plant Pathology Journal 13 Pages
한국식물병리학회 The Plant Pathology Journal 2015, 31권 4호 4 350-362 (13 pages)
A disease forecast model for bacterial grain rot (BGR) of rice, which is caused by Burkholderia glumae, was developed in this study. The model, which was named ‘BGRcast’, determined daily conduciveness of weather conditions to epidemic development of BGR and forecasted risk of BGR development. All data that were used to develop and validate the BGRcast model were collected from field observations on disease incidence at Naju, Korea during 1998?2004 and 2010. In this study, we have proposed the... -
Comparative Analysis of Defense Responses in Chocolate Spot-Resistant and -Susceptible Faba Bean (Vicia faba) Cultivars Following Infection by the Necrotrophic Fungus Botrytis fabae
한국식물병리학회 The Plant Pathology Journal 12 Pages
한국식물병리학회 The Plant Pathology Journal 2014, 30권 4호 3 355-366 (12 pages)
In this study, resistance responses were investigated during the interaction of Botrytis fabae with two faba bean cultivars expressing different levels of resistance against this pathogen, Nubaria (resistant) and Giza 40 (susceptible). Disease severity was assessed on leaves using a rating scale from 1 to 9. Accumulation levels of reactive oxygen species (ROS), lipid peroxidation and antioxidant enzymes (superoxide dismutase, catalase and ascorbate peroxidase) were measured in leaf tissues at... -

by a chitin-baiting method. This strain was identified as Burkholderia cepacia complex (Bcc) and belonging to genomovar IX (Burkholderia pyrrocinia) by colony morphology, biochemical traits and molecular method like 16S rRNA and recA gene analysis. This strain was used to develop a bio-fungicide for the control of tomato leaf mold caused by Fulvia fulva. Various formulations of B. pyrrocinia CH-67 were prepared using fermentation cultures of the bacterium in rice oil medium. The result of pot... -
Role of Gap Junctions in the Endothelium-Dependent Hyperpolarization of Vascular Smooth Muscle Cells

in both endothelial and smooth muscle cells using the double patch clamp method demonstrates that these two cell types are indeed electrically coupled, indicating that they behave as a functional syncytium. The EDHF-induced hyperpolarization is produced by an activation of Ca2-sensitive K-channels that are inhibited by charybdotoxin and apamin. Agonists that release EDHF increase [Ca2]i in endothelial cells but not in smooth muscle cells. Inhibition of gap junctions with... -
Field Sanitation and Foliar Application of Streptomyces padanus PMS-702 for the Control of Rice Sheath Blight
Chia-Jung Yang, Tzu-Pi Huang, Jenn-Wen Huang 한국식물병리학회 The Plant Pathology Journal 15 Pages

Rice sheath blight (ShB), caused by Rhizoctonia solani Kühn AG1-IA, is one of the destructive rice diseases worldwide. The aims of this study were to develop bio- control strategies focusing on field sanitation and foliar application with a biocontrol agent for ShB manage- ment. Streptomyces padanus PMS-702 showed a great antagonistic activity against R. solani. Fungichromin produced by S. padanus PMS-702, at 3.07 mg/l inhib- ited 50% mycelial growth, caused leakage of cytoplasm, and... -
Lysimachia foenum-graecum Herba Extract, a Novel Biopesticide, Inhibits ABC Transporter Genes and Mycelial Growth of Magnaporthe oryzae
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 1호 2 8-15 (8 pages)
To identify a novel biopesticide controlling rice blast disease caused by Magnaporthe oryzae, 700 plant extracts were evaluated for their inhibitory effects on mycelial growth of M. oryzae. The L. foenum-graecum Herba extract showed the lowest inhibition concentration (IC50) of 39.28 μg/ml, which is lower than the IC50 of blasticidin S (63.06 μg/ml), a conventional fungicide for rice blast disease. When treatments were combined, the IC50 of blasticidin S was dramatically reduced... -

과거 자동차는 성능위주로 개발되어 왔으며 지속적으로 증가하고 있으나 자동차에서 배출되는 배출가스는 총체적으로 환경오염에 미치는 영향이 매우 크다. 그러나 탄화수소 연료를 탈피하지 않고는 배출가스 저감을 이루기에는 어렵다. EURO-VI 규제는 질소산화물 저감을 위한 규제로 저감하기 위해서 다양한 기술이 개발되고 있다. 대표되는 기술이 LNT와 SCR이 있는데 SCR 경우는 환원제로 요소수를 분사시키는데 화학반응 과정에서 반응하지 못한 요소수는 대기로 노출되어 미세먼지 (PM)을 악화시킬 수 있다. 따라서 요소수의... -

Superhydrophobic carbon-based materials: a review of synthesis, structure, and applications
Long-Yue Meng, Soo-Jin Park 한국탄소학회 Carbon Letters 16 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.2 5 89-104 (16 pages)
Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as... -

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...
