황문규 ( Moon Qu Whang ) 전북대학교 과학교육연구소 2013 과학과 과학교육 논문지 Vol.38 No.2
작용과 반작용의 법칙으로 불리는 뉴턴의 제 3법칙을 응용하여 과학완구를 제작하는 과정과 학생활동에 적용하는 절차를 소개한다. This paper introduce how to make the rotary strow toy that explained by Newton’s 3rd law. While this work, students can apply this law to their work and they will get the correct concept by themselves.

The definition of vacuum is one of the fundamental assumptions to describe field theoretical configurations of matter and energy. The trivial definition of vacuum as the state of nothing turns out to be inconsistent since the ground states of quantum mechanical systems are known to be in the states with nonzero energies. The resolutions of these inconsistencies are very important in QCD and recent researches on these problems resulted in the suggestion of paradigm shift of QCD vacuum. We review the problems concerned about the QCD vacuum and give new perspectives which are related to hadronic and nuclear structures in coordinate space and to multi-jet phenomena in momentum space.
