The expression of the nuclear protooncogenes have been associated with the cell proliferation and differentiation into changes in nuclear function. To evaluate the possibility that the nuclear protooncogenes play roles testosterone-dependent gene regulation, the effects of testosterone on the expression of the nuclear protooncogenes have been investigated in primary Sertoli cell cultures. c-Myc, c-jun and c-fos were expressed in steady state of primary Sertoli cells but c-myb was not detected. Testosterone increased c-myc and c-jun mRNA with maximal stimulation reached in 16 h. The induction of c-myc was dependent on the concentrations of testosterone. The testsoterone induced c-myc mRNA level was also increased in the cells treated with cycloheximide, but reduced by actinomycin D pretreatment. Even in the absence of testosterone, c-myc mRNA was clearly detectable in Sertoli cells from 8-days-old rats, but hardly detectable in cells from 14 and 28 days of age. Testosterone stimulated c-myc expression in the Sertoli cells from 8 and 14-days-old rats. These results suggest that transient expression of c-myc may play some roles to an intermediate step required for testosterone-dependent regulation of other genes expression of Sertoli cells.

With the establishment of a large bookstore in Seoul in the late 1980s, and in the late 1990s, online bookstores appeared rapidly growing due to low prices and delivery surpassing offline bookstores. However, local bookstores are important places that serve as community spaces that share culture. But That disappear steadily. So this study sought through domestic and foreign case studies to solve the problem. The results of the study are as follows. The characteristic of the domestic bookstore case in terms of space two or more floors, space separation is certain for each floor, and the height of the bookshelf is lowered at eye level. And there is a space where you can read books wherever you can reach. The characteristic of overseas cases is that it induces free movement of space visitors, and the reading space are separated. The two cases are easy to communicate and experience directly. If the book community space that promotes the revitalization of our neighborhood acts and various cultural contents in the region and It becomes cultural space in the area, not only local residents but also those who want to feel the nostalgia of paper books will visit to gradually restore the community.

본 논문에서는 약간의 가정하에 리모트 제어용 모형 헬리콥터의 동역학방정식을 유도하였으며, 이를 토대로하여 헬리콥터의 자세안정을 위한 제어 알고리듬을 제안하였다. 제어이론으로서는 파라메타의 변화및 외란에 강인한 가변구조 제어이론을 활용하였다. 본 제어 알고리듬에서는 헬리콥터의 위치이동 제어에 대하여서는 다루지를 못하였으며, 단지 헬리콥터의 hovering 상태에서의 자세 안정화에만 촛점을 두어 제어 알고리듬을 제안하였다. 컴퓨터 모사를 통하여, 제안된 제어 제어 알고리듬의 타당성을 보였으며, 약 2-3초의 시간이 경과된 이후 자세가 안정화 됨을 볼 수 있었다.
