오늘의 우리 경제는 부도 직전에 IMF로부터의 긴급지원으로 가까스로 위기를 면하게 된듯하다. 그러나, 그 대가로서 감수해야 할 고통이 예상되는 것도 주지의 사실이다. 그 중에서도, 외국인의 국내기업에 대한 주식투자 한도가 무제한으로 됨에 따라, 국내 기업은 외국인 투자가들의 사냥감이 되게 되었고, 만일 외국인에 의한 인수 ( 합병을 저지하고자 한다면 국내 투자가들에 의한 인수 ( 합병이 있어야 하는 등, 소위 기업의 인수 ( 합병(M&A)이 예상되고 있다. 이러한 시점에서 본 논문은, 기업의 인수 ( 합병의 개념을 파악하고, 이러한 경우에 있어서의 독점규제 및 공정거래에 관한 법률의 규제 대상(일정한 거래분야에 있어서 경쟁을 실질적으로 제한하는 기업결합)이 되는 기업의 인수 ( 합병은 어떠한 것이며, 또한 이러한 것을 가려내는 방법 즉 판단기준은 무엇인가에 관하여, 우리 나라 공정거래위원회 및 일본의 공정거래위원회의 구체적인 심결례를 통하여 서술한다. 그러나, 현행 독점규제 및 공정거래에 관한 법률에 의할 경우에는 그 판단이 곤란한 점이 많기 때문에, 이를 보완하기 위한 법적 조치가 필요함을 지적한다.

김영환,홍원선,송재관,강윤구,이진오,강태웅,김건열,한용철 대한내과학회 1990 대한내과학회지 Vol.38 No.3

Cyclosporin A and verapamil were tested using MTT assay to evalute the modification effect on the resistance to adriamycin in a human lung cancer cell line(PC-14) and its resistant subline(PC-14/A). PC-14/A was derived by the continuous exposure of PC-14 to incremental concentrations of adriamycin. PC-14/A was 2.5 times more resistant to adriamycin in terms of ICso than PC-14. Cyclosporin A alone, at a concentration of 2.5㎍/㎖, inhibited the growth of PC-14 to 68.3%. 2.5㎍/ ㎖ and 5.0㎍/㎖ of cyclosporin A showed an increase in the cytotoxicity of adriamycin (p<0.01) with 5.0㎍/㎖ being greater than 2.5㎍/㎖(p<0.01). Excluding the direct cytotoxic effect, however, cyclosporin A did not increase in the sensitivity of PC-14 to adriamycin but only showed an additional cytotoxic effect with adriamycin. Verapamil (up to 6.0㎍/㎖) did not inhibit the growth of PC-14. 3.0㎍/㎖ of verapamil did not increase the cytotoxic effect of adriamycin. The combination of cyclosporin A and verapamil with adriamycin enhanced the cytotoxicity of adriamycin, but the result was similar to that of cyclosporin A with adriamycin. 5.0㎍/㎖ of cyclosporin A modified the adriamycin resistance of PC-14/A(SR, 3.2). However, 3.0㎍/㎖ of verapamil did not significantly reverse the adriamycin resistance of PC-14/A. The modified effect of the combination of 5.0㎍/㎖ of cyclosporin A and 3.0㎍/㎖ of verapamil was similar to that of 5.0㎍/㎖ of cyclosporin A alone in PC-14/A. These results demonstrate that cyclosporin A has an additional cytotoxic effect with adriamycin in PC-14 and PC-14/A and has overcome the acquired resistance to adriamycin in PC-14/A. They also suggest that cyclospoin A may have the therapeutic potential in the treatment of human lung cancer.

Moire topography method isa well-known non-contacting 3-D measurement method as a fast non-contact test for three-dimension shape measuring method. Recently, it's important to study the automatic three-dimension measurement by moire topography because it is frequently applied to the reverse engineering , the medical, the entertainment fields. Three-dimension measurement using projection of moire topography is very attractive because of its high measuring speed and high sensitivity. In this paper, the classical moire method is computerized-so called digital moire. when a virtual grating pattern is projected on a surface, the captured image by the CCD camera has three-dimension information of the objects. The moire image can be obtained through a simple image processing and a reference grating pattern. and it provides similar results without physical grating pattern. digital projection moire topography turns out to be very effective for the three-dimension measurement of objects. Using different N-bucket algorithm method of digital projection moire topography is tested to measuring object with the 2-ambiguity problem. Experimental results prove that the proposed scheme is capable of finding measurement errors that decreased more by using the four-three step algorithm method instead of the same step in the phase shifting of different pitch.

To identify the rice varieties adaptable for upland cultivation, a series of experiments was carried out at the field(Chonnam series) of the Muan. Cheonnam province during 1999 - 2001. Four varieties, Jinbuchalbyeo(early-maturing variety), Sinseonchalbyeo (medium-maturing variety), Dongjinchalbyeo(medium-late maturing variety), and Sangnambatbyeo as a standard variety for upland were used in this experiment. Seedling establishment of the varieties was the highest in Sangnambatbyeo and followed by Dongjinchalbyeo under upland condition. Heading date in general delayed ranges from 9 to 12 days, while early-maturing variety, Jinbuchalbyeo was faster for 3 days compared with Sangnambatbyeo. Number of panicle per square meter was similar in both lowland and upland rice but percentage of ripened grain was high in lowland rice. Milled rice yield was high as of 12% in Sinseonchalbyeo compared with Sangnambatbyeo. Head rice ratio showed also the highest in Sinseonchalbyeo. The results indicate that Sinseonchalbyeo as glutinous rice variety could adapt well in this upland condition, and have good milling recovery as head rice as well as yield advantage.
