3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.

Prebronchodilator FEV1= 2.98 L
(predicted is 4.02 L)
Postbronchodilator FEV1 = 2.75 L
FVC= 4.5 L
1) FEV1/FVC ratio
FEV1/FVC=2.98/4.5=~0.66 로 약 66%
>> 이 값이 75%이하이므로 Obstruction
2) FEV1%
(post-bronchodilator FEV1기준)
FEV1 %계산시 2.75/4.02=0.
Ⅰ. 서론
대우자동차는 폴란드의 자동차회사 FSO를 인수하여 『대우자동차 폴란드공장』을 세웠다. 인수한 공장이 제대로 모습을 갖추고 의사소통이 되지 않는 현지인들을 고용하는 등의 많은 어려움들을 대대적인 경영혁신을 통해 극복했고, 이제는 폴란드 자동차업계에서 확실한 자리를 굳히기 위
