고추씨 기름의 저장 및 가열에 따른 이화학적 변화에 관한 연구
최영진,고영수 한국조리과학회 1990 한국식품조리과학회지 Vol.6 No.2
To observe the propability as the frying oil and oxidative stability of red pepper seed oil, some physico-chemical tests of the oil were examined during 21 days storage period at 5℃, 15℃ and 30℃, and AOM value determined and after heating the oil at 180±5℃ for 40 hours with or without antioxidants. The analysis storage stability of red pepper seed oil showed that the quality of storage group at 5℃ was almost as good as fresh oil, and the storage group at 30℃ showed certain degree of rancidity. Change of physico-chemical characteristic during storage were so small so that storage stability of red pepper seed oil was found to be good. AOM stability of red pepper seed oil was 7 hours which is lower than other vegetable oil, but the degree of stability grew greatly after adding phenolic antioxidants, such on TBHQ or PG. As for the chemical change after heating continuously for 40 hours, acid value, peroxide value and refractive index increased, but iodine value decreased as the heating processed. The fatty acid composition also showed the remarkable reduction of linoleic acid. The addition of antioxidants resulted in the delay of oxidation, the degree of which was greater in TBHQ than in PG.
In silico target identification of biologically active compounds using an inverse docking simulation
최영진 셀메드 세포교정의약학회 2013 셀메드 (CellMed) Vol.3 No.2
Identification of target protein is an important procedure in the course of drug discovery. Because of complexity, action mechanisms of herbal medicine are rather obscure, unlike small-molecular drugs. Inverse docking simulation is a reverse use of molecular docking involving multiple target searches for known chemical structure. This methodology can be applied in the field of target fishing and toxicity prediction for herbal compounds as well as known drug molecules. The aim of this review is to introduce a series of in silico works for predicting potential drug targets and side-effects based on inverse docking simulations.
The PL Characteristics of ZnO Thin Film on Flexible Polymer by Pulse Laser Deposition
최영진,이천 한국전기전자재료학회 2012 Transactions on Electrical and Electronic Material Vol.13 No.5
In this study, ZnO films have been grown on PES (polyethersulfone) of flexible polymer substrate by PLD (pulsed laser deposition) and characterized for crystalline and optical properties. Growing conditions were changed with substrate temperatures ranging from 50 to 200℃ and laser power density ranging from 0.2 to 0.4 J/cm2. When ZnO thin films are deposited at low temperature with a small laser power density, the (002) peaks of XRD to signify the crystal quality of ZnO thin films appear to be very weak and the (101) peaks to signify the chemical composition of oxygen and zinc are strong. The (002) peaks increase with the substrate temperature and laser power density because the energy needed for the supply of the combination regarding zinc and oxygen has increased. In this study, the best condition for growing ZnO thin film on PES is at a substrate temperature of 200℃ and with a laser density of 0.3 J/cm2. The characteristics of PL were measured by UV and green luminescence.
