양영선,최정임 한국교육정보미디어학회 2003 교육정보미디어연구 Vol.9 No.4

본 연구의 목적은 대학에서 가상교육을 운영하기 위하여 교수와 학생들을 대상으로 가상강좌의 활용 실태와 문제점, 요구사항을 파악하기 위한 것으로, 설문 조사를 통하여 가상강좌의 운영과 수강 경험에 따른 가상강좌의 형태와 수업 방법 및 제시 자료, 가상강좌 경험에 대한 만족도를 조사하고, 가상강좌를 보다 효과적으로 운영하기 위한 조건들과 가상교육을 활성화하기 위한 의견에 대하여 조사하였다. 조사 대상은 지방의 K 대학의 교수와 학생들이었으며, 전체 교수와 학생들을 대상으로 무작위로 설문지를 배포한 결과 교수 109명과 학생 540명이 참여하였다. 요구분석 결과, 교수와 학생 모두 가상강좌의 편리성과 필요성에 대해서는 동의하였지만 가상강좌의 효과에 대해서는 회의적인 성향이 나타났다. 가상강좌가 효과적이지 못하다는 이유로는 가상강좌가 그 특성을 살린 적절한 방법으로 운영되지 못하여 상호작용과 의사소통에 많은 어려움이 있으며, 다양한 교수방법이나 교수자료가 활용되지 못하고 획일화된 강의 위주 방법이 사용되는 경향 때문인 것으로 조사되었다. 또한 대학에서 가상강좌의 활성화 필요성에 대해서는 대부분 인정을 하지만, 많은 교수들은 가상강좌 운영의 필요성에 부정적인 시각을 보였으며, 전체적으로 온라인 위주의 강의보다는 온라인과 오프라인 수업이 병행되는 형태를 선호하는 것을 발견했다. 가상강좌가 대학에서 제대로 정착하기 위해서는 무엇보다 강좌개발과 운영을 위한 인적자원의 지원, 가상강좌의 역할과 기능, 활용 방법에 대한 교수 연수가 우선되어야 함이 시사되었다. Cyber education differs from traditional education in many ways of teaching and learning, and the perception of users varies depending on the their experiences on modes and materials employed in the cyber education. In order to implement cyber education more effectively and efficiently at its beginning stage in university level, this study analyzed the degree of perception and satisfaction on cyber education as well as the problems and issues of cyber education based upon a survey. A needs analysis was conducted with two sets of questionnaires to one hundred nine professors and five hundred forty students of K university. The questionnaires consist of the types and methods of cyber lectures, the degree of satisfaction based upon their teaching and learning experiences through cyber education. It includes surveys on the professors' and students' opinions of the conditions required for implementing the successful operation of cyber lectures. The results of the study showed that although both professors and students agreed with the efficiency and needs of cyber education, they were reluctant to accept its effectiveness. The main reasons of the reluctancy appeared that cyber lecture was difficult to implement due to the lack of interactions and communication. However, it was also found that the cyber lectures applied by the professors were limited to mainly instructor-led lectures without using the mechanism and interaction of cyber education appropriately or using unique and various instructional methods and teaching materials properly. In the mode of cyber education, it was found that both the professors and students in overall preferred the blended type of cyber lectures to cyber lectures only. The professors especially suggested the necessity of the supports and training programs for implementing cyber education in their lectures.

Soybean is a crop of importance economically and nutritionally in many parts of the world. Thanks to many new genes brought from genomic research, It is possible to introduce various candidate genes through genetic transformation to see the performance of the genes in field. In our lab, soybean transformations have been tried for last 10 years to probe the possibility of traits improvement by transformation of new gene into soybean. For this purpose, three different genes were transformed into Korean soybean variety, Kwangan. First, the gene that controls early flowering of plant was transformed into Kwangan. Second, a candidate gene for soybean mosaic virus (SMV) resistance was transformed to produce transgenic plants. Third, another candidate gene for drought tolerance was transformed. All the transgenic plants from three genes transformation were produced for their gene insertion and their expression using PCR, qRT-PCR. Further analysis including harvesting seeds is currently undertaken.

국내 유통 중인 우육 및 돈육을 대상으로 S. aureus의 오염실태와 검출된 S. aureus 대한 항생제 감수성조사 및 내성 plasmid 전달빈도를 조사하였다. 총 421개 축산물 시료의 20.2%에서 S. aureus가 검출되었으며, 품목별로는 돈육 13.9%, 우육 33.8%의 검출률을 보였다. 가공 전 원료육이 포장육에 비해 S. aureus의 검출률이 높았는데, 돈육에서는 원료육 23.3%, 포장육 7.1%였고, 우육에서는 각각 48.6% 및 28.1%였다. 항생제 감수성 시험결과 ampicillin(76.5%), penicllin(75.3%), tertracycline(27.1%) 및 erythromycin(21.1%) 순으로 높은 내성률을 보였다. 특히 우육에서는 penicillin의 내성이 55.6%인 반면 돈육에서는 97.5%로 돈육에서 1.6배 이상의 높은 내성률을 보였고, tetracycline의 경우 우육에서 13.3%의 내성을 보인 반면, 돈육에서는 42.5%로 3배 이상의 내성률을 보였다. 8가지 항생제에 내성을 보이는 다제내성균도 검출되었으며, 약제내성과 관련된 Rplasmid의 특성시험에서 혼합배양에서는 내성이 전달되지 않았고, filter mating법에서 tetracycline내성 plasmid가 1.1×10<SUP>-5</SUP>~1.9×10<SUP>-9</SUP>의 빈도로, erythromycin 내성 plasmid가 1.2×10<SUP>-5</SUP>~4.0×10<SUP>-8</SUP> 빈도로 내성이 전달되었다. 따라서 국내에서는 항생제투입의 정량적인 규제나 법적인 제도장치의 마련이 시급하다고 생각되며 앞으로 항생제 사용규제 및 대책마련에 대한 추가적인 연구가 절실하다고 생각되었다. Staphylococcus aureus is a pathogene of major concern in livestock products. This study was conducted to test imported and domestic meat sold by retail stores for the presence S. aureus. In addition, the antibiotic susceptibility of any S. aureus found was also evaluated. The overall isolation rate of S. aureus was 20.2% (13.9% in pork and 33.8% in beef) in retail meats. The percentage of imported meats found to contain S. aureus (33.3% in pork and 40.4% in beef) was higher than that of domestic meat (13.0% in pork and 14.7% in beef). In addition, the detection rate of S. aureus was higher in raw material meat than in ready to cook packaged meat. When the antibiotic susceptibility of S. aureus isolated from the meat products was evaluated, ampicillin was found to be the highest (76.5%), followed by penicillin (75.3%), tetracycline (27.1%) and erythromycin (21.2%). Penicillin and tetracycline resistant were detected in 55.6% and 13.3% of the beef isolates, respectively, and 97.5% and 42.5% of the pork isolates, respectively. The tetracycline and erythromycin resistant plasmids of the isolated strain were transferred into S. aureus DPRMM2429 by the filter mating method and the frequencies of transfer was found to be 1.1×10<SUP>-5</SUP>~1.9×10<SUP>-9</SUP> and 1.2×10<SUP>-5</SUP>~4.0×10<SUP>-8</SUP> respectively.

식물은 건조 등의 스트레스 하에 놓여 있고, 수분을 효율적으로 이용하는 내건성 식물의 선발은 biomass 생산과 종보존을 위해 매우 중요하다. 본 연구는 식물의 내건성 생리적지표를 이용하여 내건성 식물을 선발하였다. 자생식물 110종 중 발아율이 높은 수종인 26종을 공시수종으로 선발했다. 내건성을 조사하기 위해 균일한 식물체에 무관수 처리하여 고사 소요일을 조사하였다. 식물의 수분스트레스에 비례하여 증가하는 프롤린 함량을 분석하여 내건성 평가지표로 활용하였다. 수분결핍에 따른 고사소요일을 조사한 결과, 2일째부터 고사하기 시작하여 10일 이후에도 생존하였다. 그 결과 새, 도깨비가지, 긴담배풀, 매듭풀, 비수리, 참느릅나무는 내건성 수종으로 입증되었다. Proline 분석 결과, proline 함량은 선발된 내건성 식물은 건조조건 부여 전과 내건성 민감성 수종보다 높았다. 본 연구는 내건성 식물종의 육종에 크게 기여할 것으로 판단된다. Many plants are stressed by prolonged periods of dry weather. Selecting trees that use water efficiently must be important in a future plant biomass and conservation. This study was selected of drought tolerance plant by using physiological indicators for drought tolerance. 110 plants germinated and highly germinating 26 species were selected. Four weeks old plants were stopped to irrigation to find out withering day by moisture deficiency. The proline content of the water stressed leaf tissues was analyzed and withering day according to moisture deficiency was examined. When stopped to irrigation, whithering day of plant species was variable from 2 to 10 days. Drought resistance plant confirmed 6 species as Ulmus parvifolia, Lespedeza cuneata, Kummerowia striata, Carpesium divaricatum, Solanum carolinense, and Arundinella hirta Proline content in selected drought tolerance plant was significantly increased than before stopped irrigation and drought susceptible plants. These results can be served breeding of drought tolerance plant from Korean native plants.
