This study was carried out to develope an alcoholic drink by fermentation of onion extract using Saccharomyces cerevisiae. The optimal conditions for ethanol production were obtained by standing culture at $25^{\circ}C$ for 5 days with 5% inoculum volume. At the results by flask culture, the growth curve of used S. cerevisiae reached to the stantionary phase at 48 hr and the death phase at 90 hr, whereas ethanol production reached maximum at 114 hr. Under the above conditions, a large scale production was carried out. A standing culture in 5 l fermenter showed the similar results to its flask culture, but progressed 24 hr rapidly more than that of the flask culture. A fed-batch culture was performed by addition of the onionic medium supplemented with 10% (v/v) sucrose after 72 hr from the fermenting start. The fed-batch culture could prevent S. cerevisiae from entering into the death phase and maintain constant level of alcohol production. A continuous culture was able to carry out by adding per every 24 hr the onionic medium supplemented with 10% (v/v) sucrose after 72 hr from the fermenting start. Although S. cerevisiae used showed a little decreased growth, alcohol production maintained roughly the constant level at the maximum yield. To enhance the quality of this alcoholic drink, $2-O-{\alpha}-D-glucopyranosyl$ L-ascorbic acid (AA-2G) was supplemented into the onion extract of the substrate for fermentation. As resulted at this study, this alcoholic drink containing AA-2G should be used as a functional fermented alcohol drink strengthened with vitamin C.

The susceptibilities of 45 clinical isolates of bacteroides frogilis to cefaclor, ciproflxacin and imipenem were determined by new method, E-test (AB Bidisk, Solna, Sweden) and were compared with those from conventional agar dilution method by using brain heart infusion, Mueller-Hinton and Wilkins Chalgren agar plates. And the susceptibility of 60 clinical isolates of Bacteroides fragilis group (B. fragilis 45 strains, B. distasonis 6 strains, B. ovatus 5 strains, B. thetaiotaomicron 4 strains) to 5 quinolones (ciprofloxacin, enoxacin, norfloxacin, ofloxacin, pefloxacin) were determined by in vitro agar dilution method. Compared with agar dilution MICs for B. fragilis 45 strains, 90.3% of E-test MICs were within ${\pm}$1 dilution of the agar dilutions, and 98.4% were within 2 dilutions. And there were little effect of different medium bases to determine MICs except Mueller-Hinton agar. On Mueller-Hinton agar, B. fragilis showed have or no growth activity. In vitro susceptibility of B. fragjlis group to quinolones, most of the test strains showed resistant patterns to quinolones except ofloxacin and there was little difference of susceptibility patterns between species of B. fragilis group.

Respiratory viruses were isolated from patients with acute respiratory infections in Busan during 2000-2001 and characterized for their antigenic properties. In 2000, 39 out of 43 isolated viruses were identified as influenza viruses and the others were adenoviruses. Among the isolated influenza viruses,23 were type A influenza viruses and 16 were type B influenza viruses. As a result of antigenic characterization, the influenza viruses were determined to A/Sydney/05/97(H3N2)-like, A/Beijing/262/95(H1N1)-like, and B/Harbin07/94-like viruses and serotypes of the isolated adenoviruses were type 1, 2, and 5. In 2001, 56 viruses were isolated and all of the viruses were identified as influenza viruses. They were A/panama/253/99(H3N2)-like and A/Newcaledonia/2007/99(H1Nl)-like viruses when determined by their antigenic properties. The sex distribution of the patients is as follows, 14 males (32.56%),23 females (67.44％) in 2000, and 23 males (41.07%), 33 females (58.93%) in 2001. Occurrence rate was found to be higher in female patients in both years. Age distribution of patients, in 2000, 48.84％ of infection occurred in 0 to 1 year old while in 2002, 33.93% occurred among 11-20 year olds. In 2000, occurrence rate was found to be high in January and again in April and various types of viruses were isolated. These results may be useful for vaccine development and establishment of reliable epidemic data.

The main purpose of Iowa Chautauqua Program(ICP) and Iowa-Scope, Sequence. and Coordination (Iowa-SS&C) was to educate K-12 science teachers so that they could teach science in a human context using the constructivist strategies. The major task for the participating teachers to perform was to develop modules with the emphasis on STS and constructivist approach. which were supposed to be taught in the respective classrooms. Teachers worked together for two weeks for the development of modules during the summer, and attempted the modules with their students. The participating teachers met regularly during the autumn semester to share and reflect their experiences and obtain additional information on science education reform and its implications. During the winter break. the teachers improved and extended the STS modules. The Iowa Chautauqua Program and Iowa-SS&C had two important implications for Korean science education. First, they made the most of the resources they had in order to provide the practicing teachers with recent research findings on the nature of science. science learning and teaching, that is. the constructivist approach. Second, they emphasized both cooperation of teachers and long-term training to realize the reform in school science education.

This experiment was conducted to find out the effects of mushroom cultivation on ozone susceptibility. The mushroom media in cultivation became softening well without bad Knell when it was soaked for 120 hours. The mushroom media softening on cultivating of oyster mushroom was good and fast when the concentration of gas condition ozone is high. The concentration of gas condition ozone must control at less than 0.02 ppm at the innoculation room, 0.03 ppm at the incubating room, must not use at the sprouting mom, less than 0.02 ppm at the growing room respectively. Also at the growing room, it removes the smell of mushroom, so has a protective effects of coming into mushroom fees and disease. When the concentration of 0.02 ppm liquid condition ozone was sprinkled, it was very useful in disease protection If it was input, the storage period of mushroom fruiting body was prolonged.

This study aimed to analyze the relative influence of related variables on the university students' civic consciousness. The study sorted out the data for 1,200 university students from a larger data set collected by Son et al.(2009), and analyzed the data by a hierarchical regression analysis method. The study showed the major results in four aspects. First, personal characteristics and home environment variables had mostly no influence on the students' civic consciousness. Second, on the sub categories of the students' civic consciousness, almost no influence was found in case of the home environment variables on democratic constitution and participation-practice, and in case of the school environment variables on value and attitude. Third, among the home and school variables, parents' attitude(${\beta}$=.228) and professors(${\beta}$=.162) had positive influences on the students' civic consciousness. The results suggest that parents and professors should be the two principal axises in the cultivating process of the students' civic consciousness. Third, on the democratic participation and practice no positive influences were found in any of the social environment variables. Among the social environment variables, politicians(${\beta}$=-.238) and corporations(${\beta}$=-.097) had rather negative influences on the democratic participation and practice. These results raised the question on how school education and social political systems are operated in the democratic manners. Fourth, the study recommends that local government would establish the civic education centers, develop various civic education programs, and provide each school with the programs. The study also recommends that each university would democratize in all the school affairs, and actively implement the civic education for university students as a specialized project.

In a broad range of socio-economic and political systems, we could be able to say that the common and highest goal of all nations is the well-being of the people. From this point of view, it can be seen that two significant historic developments were achieved in the 20th century. One was the maximization of productivity through the socially efficient distribution of resources and the other was the concept of national welfare, which assumes social responsibility for the basic livelihood of human beings. In this point, it is need not only to strengthen economic wealth, but also to redistribute resources equitably. Efficiency and equity, economic and growth, and national welfare emphasize the above-mentioned principle, but they are deeply interdependent in that the well-being of the people cannot be guaranteed in the presence of only one of those. This study aims to find out the equilibrium point those problems in the productive welfare policy in Korea. Finally, it is necessary to develop productive welfare systems in order to solve the issues well.

The geology of Hidalgo state in Mexico is formed by a Precambrian metamorphic rock base which discordantly supports a strong Paleozoic sedimentary rock sequence. Triassic-Jurassic and Cretaceous sedimentary rocks overlie the above-mentioned rocks at a discordant angle. These Mesozoic rocks are in turn covered by a Cenozoic structure which is marine at its base. At the top, the structure changes to andesitic and basaltic composition volcanic rocks. And, a great variety of mineral deposits, both metallic and nonmetallic, is present in Hidalgo state. The host rocks of these deposits are also very varied in age from Mesozoic to Tertiary. Mineralization age corresponds to Tertiary in 90% of the area. Hidalgo state occupies as an important place in national silver and manganese production. Main mineral deposits correspond to argentiferous veins hosted in sedimentary rocks. Following in order of importance are lead and zinc, as well as some small iron deposits. There is evidence of tin and molybdenum mineralization, but these deposits have not been exploited because of their low grade and volume. And, Hidalgo state has different types of nonmetallic mineral deposits such as sedimentary, hydrothermal, metamorphic and volcanic origins.

중의학은 서양의 의료 다원주의의 한 부분이 되었다. 특히 침과 같이 서양의 개념과는 분명히 다른 의료 기법에 있어서는 두드러진다. 그밖에 뜸, 안마, 기공, 중약 및 복합 처방들도 있다. 서양에서 전문직업인화는 보건의료 관련분야에서 중심적인 인력양성 방법이 되었다. 이는 대학이 기반을 다진 중세까지 거슬러 올라가는데, 19세기에는 법인들이 전문직업인 모임으로 바뀌어 가면서 개인적 환경을 변화시키고 직업의 체계를 개발하였다. 변호사, 교사, 사제, 의사가 그 예이다. 의료에 있어서 학교교육을 통해 수련된 의사들이 조산사나 안마사들을 지배하게 되었는데 이런 경향은 1950-60년대에 극에 달한다. 그러다가 이들의 지배는 대중매체, 환자, 다른 주변 의료 보조인력들에 의해 도전을 받는다. 이와 비슷한 양상을 이단적인 의료에서도 관찰할 수 있다. 전문직업인의 우세와 시점이 비슷한 생물의학의 우월적 지배는 많은 다양한 의료에 의해 도전을 받는다. 그러나 생물의학의 우월함의 약세가 시술자들의 전문직업인화 까지를 포함하지는 않았다. 실제로 침술과 같은 치료술들을 전문직업인인 의사나 의사가 아닌 시술자들이 함께 쓰고 있기 때문이다. 이는 직능간의 분쟁을 야기할 가능성이 높다. 이단적 개념을 기존 의료계로 통합하는 것이 전문직업인들인 의사들의 노력으로 이해되었다. 이 견해는 두 가지 문제를 내포하고 있는데, 첫째 의사들을 단일한 속성으로 보고 있다는 것인데, 실제로 현대의학을 배우고 가르치는 나라들 사이에도 매우 다양한 차이가 있음을 간과하고 있다. 둘째로 의료인이 아닌 시술자들도 다양한 분야로 통합되었는데, 통합은 어쩌면 하급의 전문인들의 노력의 결과로 설명되어야 하는 것이 더 알맞을 수 있다. 그러나 이들도 전문직업인의 조직구조를 가져야 만 하고, 그렇지 않으면 파편으로 남을 것이다. 전문직업인주의는 언제나 과학과 연계하고 있는데, 독일 정부와 직업인 조직은 의료과학 집단에게 이단적 시술들의 임상효과를 검증하게 하였다. 이것은 이단 의료계에 우호적인 단체나 적대적인 단체 모두에게 적용되었다. 매우 강한 힘을 가진 냉소적인 조직 가운데 하나는 National Committee of SHI-Physicians and Sickness Funds(Bundesausschuss der Arzte und Krankenkassen).2 인데, 2001년에, 이 단체에서 출판한 자료에는 침의 효용성은 침을 시술하는 사람에 달린 것 일뿐 시술자의 수련이나 침 시술의 배경 개념에 달려있는 것이 아니다. 그러므로 침은 무작위 표본추출 대조군 실험을 통해 효과를 검증받지 못한 다른 치료법들의 범주에 머물러 있다.(cf. Bundesausschuss 2001: 8). 1990년대, 무작위 표본추출 대조군 실험은 생물의학이 아닌 의료의 효과를 검증하는데 알맞지 않고 비윤리적이라고 강한 비판을 받았다. 한편 1995년에 WHO는 침의 유효성 평가를 위해 이 실험기법을 추천하며, 이어 2001년에, the International Council of Medical Acupuncture and Related Techniques(ICMART)는 침연구와 시술을 위한 헌장(Acupuncture Charter Berlin an Evidence Based Medicine (EBM)3 for acupuncture)을 채택 공표한다. 독일 보험 회사들도 침의 효과와 효율성을 검증하기 위해 대규모 실험을 시작했다. 100,000 명이 넘는 환자들이 무작위 표본추출 대조군 실험을 통해 평가되고 있는데 이 실험은 병원이나 일차의료기관의 외래에서 진행되고 있다. 영국에서는 이 분야의 유력한 Edzard Ernst가 위의 개념과 비슷한 구도를 설정 공표하는데 보완의학 분야의 많은 다른 전문가들의 견해를 무릎 쓰고, 그는 증거기반 의학에 대한 그의 신념을 표방한다. "무작위 표본추출 대조군 실험이 보환의학 분야의 시술을 검증하기 위한 알맞은 방법이 아니라고 끝없이 주장하지만 우리는 거의 모든 치료법을 포괄하는 분야에 이들 실험을 발견하였으니, 이는 보완의학도 엄정한 방법으로 검증할 수 있다는 것을 보여준다고 할 수 있다."(Ernst et al. 2001: xiii). 적어도 독일에서 진행중인 효과 검증 연구가 향후 아시아 의학의 기반 마련에 중요한 역할을 하게 될 것이다. 영국에서는 이에 대한 정치적 수렴이 전문 직업인화에 달려 있을 것이다. 여기에서 나는 아시아에서 유래한 의료의 서양에서 어떻게 사회학적 관찰의 대상으로 분류되고 정의되는지 소개하고자 한다.
