We have evaluated the effects of experimental factors on transmitted electron beam intensities for quantitative analysis in electron tomography. For the correct application of Beer's law in electron tomography, the transmitted beam intensity should reflect the net effect of mass properties on beam path. So, the any other effects of the objective aperture and the specimen holder on beam path should be removed. The cut-off effects of objective aperture were examined using Quanti-foil holey carbon film and a transmission electron microscope operated at 120 kV. The transmitted beam intensities with $30{\mu}m$ objective aperture dropped about 16.7% compared to electron beam intensities without the objective aperture. Also, the additional losses of about 14.2% at high tilt angles were occurred by cut-off effects of the objective apertures. For the precise quantitative analysis in electron tomography, the effect of the objective aperture on transmitted electron beam intensities should be considered. It is desirable that 2-D tilt series images are obtained without the objective aperture for correct application of Bee's law.

The purpose of this study was to examine the use of different sorts of Korean traditional liquor among male and female adults in Seoul and Gyeonggi province, their awareness of them and their preference in an effort to discuss what problems Korean traditional liquors were faced with and how they could gain popularity among people in general. First, It is investigated of drinking frequency by gender, 51.3 percent of the male adults drunk once or twice a week, and 33.2 percent of the female adults drunk once or twice a month. Thus, the men drunk more often than the women. By age, the adults who were in their 20s and 30s were far different from those who were in their 50s above in drinking frequency. Second, regarding what kind of liquor they enjoyed, the men enjoyed Soju the most, followed by beer and traditional liquors. The women enjoyed beer the most, followed by Soju and wine. The favorite liquor of the men was Soju, followed by beer and traditional liquor, and the women most liked for beer, followed by wine and Soju. The female adults preferred low-proof liquor more than the male adults. Third, concerning their awareness of traditional liquor, Andong-soju was most widely viewed as traditional liquor, which were followed by Munbaeju, Gyeongju-gyodongbeopju, Gyeongju-beopju, Gukhwaju, Ssal- makgeolri, and Geumsan-insamju. Overall, they were rarely aware what traditional liquor was. Fourth, as to purchase experience, the men and the older people had more experience to buy traditional drinks than the women and the younger ones. Fifth, as for anju (dishes for traditional drinks), they believed that panfried food and Kimchi should be served with coarse liquor. Panfried and streamed dishes were considered to be good complements to Takju (rice wine) and Cheongju (clear strained rice wine), and pot stew and soup were looked upon as good complements to distilled liquor. The above-mentioned findings illustrated that in order to step up the development of the traditional liquor industry, perpetual research efforts should be put into adding new tastes to unique traditional liquor drinks. And it's required to commercialize those drinks, and multiple P.R. and marketing strategies should be prepared to promote their sales.

맥주의 한sod 혼탁방지용으로 널리 사용되고 있는 papain을 미생물 효소로써 대치할 목적으로 토양에서 분리한 148주의 균주가운데서 Bacillus 속이라고 추정되는 한 균주를 선택하여 효소를 생산하였다. 이 효소는 제탁 능력에 있어서 시판의 protesal에 비등하며 저장시에는 pH7-8, 온도 $35^{\circ}C$ 이하에서 안정성이 확인되어 충분히 실용가치가 있는 것으로 본다.

Cancer has been important cause of human mortality. It was known that about one third of all deaths from cancer may be ascribed to diet habits. To identify food and drinks which could protect against cancer is important. Antimutagenicity and anticarcinogenicity of dietary components are being studied extensively.(omitted)
