Synthetic potassium channel openers (KCOs) are agents capable of opening K-channels in excitable cells. These agents are known to have their maximal potency in the smooth muscle tissue, especially in the vascular smooth muscle. Much attention has been focused on the type of K-channel that is responsible for mediating the effects of KCOs. As the KCO-induced changes are antagonized by glibenclamide, an KATP (ATP-sensitive K-channel) blocker in the pancreatic β-cell, KATP was suggested to be the... -

이 연구의 목적은 자기결정성이론을 바탕으로 중학생이 인식하는 학교풍토, 자아탄력성의 궤적, 자기주도학습의 관계를 살펴보고자 한 것이다. 자기결정성 이론 중 기본심리욕구 이론에 기반을 둘 때, 학교풍토는 개인의 심리적 성장을 가능하게 하는 하나의 맥락으로 볼 수 있다. 그리고 학교풍토를 통해 자아탄력성과 같은 심리적 성장이 가능할 때 학습현장에서 청소년의 자기주도학습 수준이 향상될 수 있다. 이 연구는 이러한 이론적 가정을 실증적으로 검증하는 것을 목적으로 하였다. 이를위해 서울교육종단연구(SELS 2010)의... -

As a part of the electromagnetic spectrum, microwaves heat materials fast and efficiently via direct energy transfer, while conventional heating methods rely on conduction and convection. To date, the use of microwave heating in the research of carbon-based materials has been mainly limited to liquid solutions. However, more rapid and efficient heating is possible in electron-rich solid materials, because the target materials absorb the energy of microwaves effectively and exclusively.... -
