Comparative Molecular Field Analysis(CoMFA) of Antitumor Benzo[c] phenanthridine Derivatives
Cho, Won Jea,Yoo, Su Jeong,Park, Myun Ji 전남대학교 약품개발연구소 1996 약품개발연구지 Vol.5 No.1
Comparative molecular field analysis (CoMFA) was applied to a set of antitumor benzo[c]phenanthridines as well as 3-arylisoquinolin-1(2H)-ores. The results indicate a strong correlation between the cytotoxic activity of these compounds against human colon tumor cell (HCT 15) and the electrostatic, steric, and cLogP factors, among which the contribution of electrostatic factor was the test important. CoMFA quantitative structure-activity relationship models exhibited considerable predictive ability.
Effects of HACCP System Implementation on Medicine Use and Productivity of Swine Farms in Korea

This study was conducted to examine the effect of HACCP implementation on the cost of medicine use, antibiotic utilization, and productivity of swine in Korea. Data were collected from forty-five swine farms before and after implementation of a HACCP system. The cost of medicine used, the number of different antibiotics used and the number of feeds containing antibiotic supplements added at the feed company tended to be lower (p>0.05) after HACCP implementation. Additionally, the number of feeds containing antibiotics supplemented at the farm was significantly lower after HACCP implementation (p

Considering the environmental concerns, limitation of natural resources and power demand pressure, there is a great need to involve the distributed energy resource (DER) which can be operated as interconnected or as stand-alone mode from the main power grid. This paper proposes an application of Matlab/Stateflow-based MAS for energy management and control in a hybrid energy system including diesel generation system. An overall power management strategy is designed for the proposed system to manage power flows among different energy sources and the storage unit in the system. A simulation model for the hybrid energy system was developed using Matlab/Simulink and SimPowerSystems. The system performance under the different scenarios was verified by carrying out simulation studies using practical load demand profile and real weather data.

Synthetic Approaches to Natural Antioxidant Benzastatin E, F and G Analogues
Won-Jea Cho,Thanh Nguyen Le,양수희,Daulat Bikram Khadka,Suk Hee Cho,Chao Zhao 대한화학회 2011 Bulletin of the Korean Chemical Society Vol.32 No.12
For synthesis of benzastatin E, F and G analogues, the indole-2-carbaldehydes with or without substituents at C-5 position were prepared as key intermediates. Several synthetic attempts to achieve benzastatin E-G analogues were suggested using the indole-2-carbaldehyde intermediates.
