  • 본 조사지역은 조수보호지역으로 대부분 지정되어 있어 동식물에 대하여 유의해야 한다. 따라서 현 서식환경을 대폭 변화시키는 대규모 개발을 억제하고 대형 콘크리트 구조물 등으로 인하여 서식지역과 개체군 분단에 주의해야할 것이다. 도로개축에 있어서는 특이 사항이 발견되지 않았으나 무까천에 공사 중에 토사유입을 주의하고 땅밀림 지역과 하안 침식지역의 정밀조사가 요구되었다.

  • We have developed the testing software for KEPCO operators to maintain the small-scale distribution automation system effectively. The testing software is used to monitor the present status, to measure the analog value(voltage, amperage) and to control the switch and FRTU(Feeder Remote Terminal Unit) in order to find out a disabled part of the system. And at the stage of inspection of the switch and FRTU, it can screen the inferior one.

  • New materials are being considered for insulator of railroad vehicles. Because people want more environmental material than glass fiber, there are certain needs of finding safe and economical insulating material. We checked the flammability of some kinds insulators such as PE foam, neoprene rubber foam. melamine foam and glass fiber. You could find out the characteristics such as oxygen index. optical smoke density, toxicity index of that insulators.
