This experiment was carried out to increase productivity of low productive fields (now producing less than 180kg per 10a ) at the Eumseong Tobacco Experiment Station in 1976- 1977. We could produce 220kg or more of yields (Hicks ) per 10a by increasing plant density to 2778 plants/10a and applying 20% more fertilizer than the recommended amount.

에어 베어링은 높은 강성과 낮은 마찰력과 같은 장점들로 인하여 높은 정밀도를 요구하는 반도체나 디스플레이 장비의 선형 스테이지에 주로 사용 되어지고 있다. 하지만 현재까지 높은 정밀도를 요구하는 회전형 스테이지에는 아직까지 크로스 롤러링을 이용하여 가이드를 하고 있다. 본 논문에서는 높은 정밀도를 갖는 회전 스테이지의 설계를 위하여 구동 성능과 오차요소에 대한 성능에 대해 설계 목표를 제시 하였고 이러한 스테이지를 구현하기 위해 에어베어링을 적용한 회전형 스테이지를 설계하였다.

This study was conducted to investigate the effects of time management behavioral therapy program on self-esteem, stress coping of school maladjusted adolescents. Experiment was conducted with 8 school maladjusted adolescents who were helped in living facilities. Time management behavioral therapy was applied to adolescents 16 weeks. To achieve the purpose of this study, self-esteem scale and stress coping scale were analyzed and compared before and after intervention. The results of this study were as follows: School maladjusted adolescents showed the significant increase in self-esteem. and School maladjusted adolescents showed the significant increase in active and passive coping of stress by intervention. It was proven to have positive effects on stress coping by intervention in a short time. Through the results of this study, time management behavioral therapy program was proven to have positive effects on self-esteem, stress coping of school maladjusted adolescents.
