CMM을 이용한 Airfoil의 Edge부위 측정오차 최소화를 위한 Fitting방법
강진우,변재현 한국경영과학회 2000 한국경영과학회 학술대회논문집 Vol.- No.1
본 연구는 turbine compressor airfoil의 측정 및 검사 업무에서 edge(leading edge/trailing edge) 부위에서 자주 발생하는 프로브 slip현상으로 인한 측정 오차를 최소화하기 위하여 터빈 압축기의 airfoil 형상 규격에 대하여 살펴보고, 균일 샘플링방법을 이용하여 최소제곱법으로 보상하여 최적의 형상을 구하는 방법을 제시하고자 한다. 국내 기업에서는 airfoil형상의 edge부위들 검사할 때 leading edge부위의 타원 형상과 trailing edge부위의 원 형상을 AutoCAD상에서 임의로 그려서 규격을 검사하고 있다. 따라서 본 연구에서는 edge부위에서 발생하는 측정오차를 최소화하기 위하여 보다 정확하고 체계적인 fitting 방법을 도입함으로써, airfoil의 형상치수에 관한 규격검사 업무의 신뢰성과 효율을 향상 시키고자 한다.
전통연극의 창조적 계승 : <물도리동>, <원귀마당쇠>의 신명을 중심으로

Sinmyung is obtained when the people think with their identity recognized. When the people participate in Mask dance, their characters try to overcome suppression they have in minds. Through this experience they learn and develop the skills needed to deal with real-life hardships. Because of such experience in playing, they are able to gain confidence and a sense of security, which foster a more optimistic outlook of the world. <Hahwoe mask dance>was origin traditional drama and <Muldoridong> is recent accession drama. The only way to get Sinmyung in the play is to incorporate people’s desires to the story. For The play <Muldoridong>, the story combined a national formality with tragic elements that were narrowed down from these desires. <Wonguimadangsoe> did not have the complete form of madang drama. The critical consciousness and dramatic techniques, which were converted from traditional mask-dance, are consistent with the contemporary meaning of the play. This method seems to have contributed to the improved formation of the current madang drama. However, the dramatic techniques in mask dance, pansori, gut must be inherited by the people in order for improvement; it is irrational to claim that they must be kept as is. It is important to combine a traditional spirit with dramatic methods in order for the techniques to have its meaning. <Muldoridong> excluded the problems of the world that are essential to traditional disregarded communication with the audience. As a result of overcoming these obstacles, the new <Wonguimadangsoe> was formed and became the exemplar creation of the commoner’s play these days.

Experimentally, the aligned direction of AFLCs in electro-optic cells having both the substrates rubbed along the same direction is skewed by a few degrees from the rebbing direction. To explain why, we proposed "Torsional Rigid Body Model" and interpreted their skewing angle as the action of short pitch with the large shear stress. That is, the azimuthal an anchoring strength (about 35 dyn/cm) in the cell is much larger than the maximum shear stress (about 10$^{-6}$ dyn/cm) for the original pitch and so forbids the optic axis to skew. On the side hand, the strength is smaller than the maximum shear stress (about 42 dyn/cm) for short pitch and then allows the optic axis to skew.
