$K_2O{cdot}CaO{cdot}P_2O_5$를 기본조성으로 하여 용융법에 의해 유리 형성범위를 정의하고자 하였다. TG-DTA와 DSC를 이용하여 열적 특성을 관찰하고자 하였으며, FT-IR과 Raman Spectroscopy를 이용하여 구조를 분석하였다. $K_2O{cdot}CaO{cdot}P_2O_5$의 함량이 증가함에 따라 유리전이온도 및 연화온도는 감소하였다. $K_2O{cdot}CaO{cdot}P_2O_5$ 유리의 기본 구조는 이웃한 구조와 상호 결합을 위한 $PO_2$와 $PO_4^{3-}$ 구조와 유리의 골격구조를 이루는 P-O-P 결합이며, CaO의 함량이 증가함에 따라, 유리내의 P-O-P의... -
Control Efficacy of Bacillus velezensis AFB2-2 against Potato Late Blight Caused by Phytophthora infestans in Organic Potato Cultivation
Min Jeong Kim, Chang Ki Shim, Jong-Ho Park 한국식물병리학회 The Plant Pathology Journal 16 Pages
한국식물병리학회 The Plant Pathology Journal 2021, 37권 6호 8 580-595 (16 pages)
Although late blight is an important disease in eco- friendly potato cultivation in Korea, it is highly depen- dent on the use of eco-friendly agricultural materials and the development of biological control technology is low. It is a necessary to develop an effective biocontrol agent to inactivate late blight in the field. AFB2-2 strain is a gram-positive with peritrichous flagella. It can uti- lize 20 types of carbon sources, like L-arabinose, and D- trehalose at 35°C. The optimal growth... -
Menadione Sodium Bisulfite-Protected Tomato Leaves against Grey Mould via Antifungal Activity and Enhanced Plant Immunity

Tomato grey mould has been one of the destructive fungal diseases during tomato production. Ten mM of menadione sodium bisulfite (MSB) was applied to tomato plants for eco-friendly control of the grey mould. MSB-reduced tomato grey mould in the 3rd true leaves was prolonged at least 7 days prior to the fungal inoculation of two inoculum densities (2 × 104 and 2 × 105 co- nidia/ml) of Botrytis cinerea. Protection efficacy was significantly higher in the leaves inoculated with the lower disease... -
Short-Term Effects of Low-Level Heavy Metal Contamination on Soil Health Analyzed by Nematode Community Structure
한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 4호 6 329-339 (11 pages)
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... -
Evaluation of the Biocontrol Potential of Some Medicinal Plant Materials Alone and in Combination with Trichoderma harzianum Against Rhizoctonia solani AG 2-1
한국식물병리학회 The Plant Pathology Journal 10 Pages
한국식물병리학회 The Plant Pathology Journal 2011, 27권 1호 11 68-77 (10 pages)
Fifty five species of medicinal plant materials were tested for their antifungal activity in vitro against Rhizoctonia solani AG 2-1 and Trichoderma harzianum to select plant species that can be used to improve the biocontrol efficacy of T. harzianum. Six species were effective against R. solani AG 2-1 but were also antagonistic to T. harzianum, except for Cinnamomum loureirii stem bark (CSB). CSB inhibited mycelial growth of R. solani AG 2-1 by 73.7% but showed an inhibitory effect on mycelial... -

폐FRP 선박을 재활용하는 기술은 많은 발전을 이루어 왔으며 최근에는 가장 재활용도가 적은 부분인 유리섬유의 고부가치화 재활용이 특히 주목받고 있다. 폐FRP 선박의 재처리 과정에서 추출된 유리섬유는 피막된 수지 성분의 내화학성으로 인하여 섬유보강재로서 사용 가능하다는 것이 보고되었다. 그러나 섬유보강재(laminated glass fiber reinforced material)를 추출하는 공정의 효율성과 경제성의 재고는 개선되어여할 과제이다. 본 연구는 다층구조인 FRP로부터 면포층(roving cloth layer)을 보다 효과적으로 박리할 수 있는... -

Electrical energy can be converted into heat energy through ohmic joule heating. Metallic materials are typically used in electrical heating elements because of their great electrical conductivity. However, metallic materials have several weaknesses, such as corrosion susceptibility, heavy weight, high manufacturing costs, and electromagnetic wave emissions [1,2]. To resolve these problems, carbon materials with good electrical conductivity, such as carbon fibers, graphite fibers, carbon...
