2009년도부터 우리나라에서 주목을 받기 시작한 스마트그리드(Smart Grid)는 녹색성장을 이끌 주역으로 평가되어 왔고, 2010년도에는 제주 스마트그리드 실증단지에서 본격적인 사업을 추진하고 있다. 기존의 전력망은 발전, 송변전, 배전 그리고 소비로 이어지는 구성으로 되어 있으나 최근 유가 상승과 지구온난화가 이슈로 부각되면서 신재생에너지원과 전기자동차 등 새로운 발전원과 수요원이 등장하였다. 이에 따라 다양하게 변화하는 도시환경 속에서 전력을 안정적으로 공급하고 계통을 효율적으로 운용할 수 있는 방법과 예측이 필요하게 되었다. 따라서 본 연구에서는 미니어처 기법을 이용하여 도시기반시설에 공급하는 전력계통에 정보 · 통신기술을 접목된 스마트그리드의 기술구현 모델을 정립하고자 한다.

This study was undertaken to investigate effects of isometric and isotonic exercise on the plasma levels of creatine phosphokinase (CPK), total cholestrol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), glucose, and cortisol and heart rate (HR) in twenty healthy adults. Prior to the exercise the baseline level was taken from blood sampling after resting for thirty minutes. The subjects were divided Into two groups by ten ; one for isometric, the other for isotonic exercise. Physical exercise was performed by twenty minutes a day for 5 days. As compared with the baseline level, the plasma cortisol level increased significantly after isometric exercise and the plasma CPK level increased significantly after isotonic exercise (p<0.05). There is no significant change in the levels of plasma TC, TG, HDL, LDL, and glucose after exorcise in both groups. Heart rate increased more rapidly in isometric exercise than in isotonic exercise (p<0.05). Key words : isometric exercise, isotonic exercise

To investigate the influences of underground water on normal adults, serial measurements of blood pressure(BP), pulse rate(PR), electrocardiogram(EKG), transcranial doppler sonography(TCD), quantitative electroencephalogram(QEEG), visual evoked potential(VEP), and cognitive evoked potential by auditory stimulation(P3O0) were performed on thirty one normal healthy adults before and after exposure for one hour to the zone of harmful radiation in underground water. The results were as follows ; 1) There were no significant differences in BP, PR, results of EKG, and QEEG in comparison of before and after exposure to the zone of harmful radiation in underground water. 2) There were no significant differences in mean blood flow velocity, resistance index, and pulsatility index by TCD in comparison of before and after exposure to the zone of harmful radiation in underground water. 3) The VEP study revealed no significant change in P1OO latency(p>O.05) but there was significant decrease in amplitude in comparison of before and after exposure to the zone of harmful radiation in underground water. 4) The P300 study revealed no significant change in P300 latency(P>O.05) but there was significant decrease in amplitude in comparison of before and after exposure to the zone of harmful radiation in underground water. In conclusion, despite its unidentified underlying mechanism, radiation in underground water may influence inhibitory effects of perception by the brain and the heurophysiological pathway of vision.
