본 연구는 lysimeter에서 돈분액비, 톱밥발효 돈분 및 화학비료를 각각 100, 200, 400kg/ha 수준으로 시용하였을 때 옥수수의 생산성, 질소의 이용효율 및 N 와 P 용탈에 의한 환경 오염에 미치는 영향을 정확히 규명, 가축분뇨의 자원화는 물론 가축분뇨에 의한 환경오염 방지대책 수립을 위한 기초자료를 제공하고자 수행되었으며 그 연구결과는 다음과 같다. 1. 옥수수의 건물수량은 돈분액비, 톱밥발효 돈분 및 화학비료 모두 시용수준과 비례하여

We carried out this experiment to observe electrochemical properties for LB films of phospholipid(Dilauroyl-L-α-Phosphayidylcholine) and 4-octyl-4'-(5-carboxypentamethylene-oxy)azobenzene mixture by the cyclic voltammetry. LB films of 8A5H and 8A5H-DLPC(1:1, 2:1) were deposited by using the Langmuir-Blodgett method on the ITO glass. We determined electrochemical measurement by using cyclic voltammetry with a three-electrode system, An Ag/AgCl reference elect rode, a platinum wire counter electrode and LB film-coated ITO working electrode measured in 0.1, 0.5, and 1.0 mol/L NaClO4 solution. A measuring range was reduced from initial potential to -1350 mV, continuously oxidized to 1650 mV and measured to the initial point. The scan rate were 50, 100, 150 and 200 mV/s. As a result, LB films of 8A5H 8A5H-DLPC appeared irreversible process caused by only the oxidation current from the cyclic voltammogram.
