개인용 컴퓨터 (personal computer) ¹)²)를 사용하여 중등학교 수학 물리 생물등 과학과목과 대학교 외에 일반적으로 널리 이용되는 통계 패키지 프로그램 (package progaam)을 개발하였다. 이 패키지는 한글모듈과 프린트 명령이 있기 때문에 어떤 PC한 세트만 있으면 쉽게 통계값을 구할 수 있다. 또한 KOREA, PASS, EDU-W 프로그램을 첨부하면 영어로 사용할 수 있게 됨이 確實視된다. Statistic Package Program used widespreadly, using personal Computer, is developed for the general purposes involving science subjects such as mathema-tics, physics and biology etc in middle-high schools and universities. Because there are Korean language module and printing instruction in this package, we can get statistic value easily with a PC set. Also, if we add KOREA, PASS, EDU-W Program, it will be certain that we can easily use into Korean any soft-ware written in English.

Large cities in Korea devoted themselves in many respects to the elevation of the production efficiency and the development of medium and small size cities thanks to agglomeration economies. The concentration of the population in large cities, however, resulted in an excessive inter-regional imblance, conjestion, and environmental contamination. We are almost incapable of figuring out an optimal size of cities, but we must try to measure it econometrically. There seems to be a lot of courterplans againt the concentration of population in the capital district but is only one precedent condition-local self government. Inquiring into the trend of urbanization in Korea from 1960 until 1980, the order of the size of large cities has not changed greatly and the growth of the coastal industrial cities such as Ulsan, Masan and Pohang is remarkably perceibable. The growth rate of Seoul stands on the second position and this brings us to awareness of the danger of the concentration of population. The numerical value of statistics made by an institute was not equal to that drawn up by another. Data must be deliberately collected and arranged.
정상교합자의 치축경사도에 관한 45。측모두부방사선 계측학적 연구
김경호,박영철 대한치과교정학회 1988 대한치과교정학회지 Vol.18 No.1
The development of good arch form, the orientation of the dentition with relation to the craniofacial skeleton and the establishment of correct relationship of axial inclination of upper and lower teeth are required in normal occlusion, but different teeth present different degrees of axial inclination. The purpose of this study was to investigate the axial inclination of upper and lower teeth by analyzing 45。 oblique and 90。 cephalometric roentgenograms of 35 Korean males and 34 females with normal occlusion. The obtained results were as follows: 1. Mean and standard deviation of mesiodistal axial inclination of upper and lower teeth related to palatal plane and occlusal plane were obtained. 2. Mesiodistal axial inclination of upper first premolar was nearly perpendicular to palatal plane, and the axis of lower first premolar was nearly perpendicular to occlusal plane. 3. There was no difference in the mesiodistal axial inclination of anteriorly positioned teeth between the three groups: third molar eruption into good alignment (Group 1), third molar impaction or partial eruption (Group 2), third molar agenesis(Group 3). 4. There were low correlationships only between the axial inclination of central incisor and the mesiodistal axial inclination of canine and first premolar, but no correlationships between central incisor and posterior teeth behind first premolar.
