이 연구는 초·중고 학생들의 과학 정의적 특성을 비교 분석하여 과학 정의적 영역에 대한 학생들의 특성을 알아보고, 더 나아가 초·중·고 학생들에게 바람직한 과학적 인식, 흥미, 태도를 함양하여 앞으로의 과학 교육의 내용과 방향을 제시하고자 하는데 목적이 있다. 이를 위해 2011년 2월에 초중고 학생 595을 대상으로 과학의 정의적 특성을 조사하였다. 본 연구의 결과는 과학 정의적 특성의 평균 점수가 초등학교 5학년에서 중학교2학년으로 올라가면서 통계적으로 유의하게(p<.05) 하락한 후 고등학교 1학년에서 상승하는 것으로 나타났다. 또한 남학생이 여학생보다 통계적으로 유의하게(p<.05) 높은 점수가 나타났다. 초등학교 5학년과 고등학교 1학년은 과학적 태도에서 유의미한 차이가 나타나지 않았으며, 중학교 2학년에서는 과학에 대한 인식에서 유의미한 차이가 나타나지 않고 있다. 본 연구 결과에 의하면 초등학교에서 중·고등학교로 진학하면서 과학에 대한 정의적 특성 성취 점수가 낮아지는 것을 보면 학생들에게 과학 수업에 대한 흥미와 태도를 높일 수 있도록 과학교육과정에서 내용과 방향에 대한 개선을 모색해야 할 필요가 있다. 또한 여학생의 과학에 대한 인식, 흥미, 태도를 향상 시킬 수 있는 교수-학습 과정을 모색하며 과학의 성취 수준에 대한 계속적인 분석을 통해 과학 교육의 질적 향상을 해야 한다고 생각한다. The purpose of this study was to investigate students` achievement of science affective domain. Achievement of science-related affective domain of elementary, middle, and high school students according to grades and gender was analyzed. The number of students who responded the questionnaire of science-related affective domain was 595, consisted of 172 elementary school students, 193 middle school students and 230 high school students in the same city. The students answered were 302 boys and 293 girls. The questionnaire of science-related affective domain developed by Hyo-Nam Kim and her colleagues was used. The questionnaire consisted of cognition of science, interest toward science, and scientific attitude. The reliability of the instrument was .86. The result of this study are as follows: First, the fifth graders showed the highest achievement of science-related affective domain, and the tenth graders were followed. The middle school students showed the lowest achievement of science-related affective doaim. Second, the boys showed higher achievement of science-related affective domain than girls. To maintain interest toward science and scientific attitude of students science curriculum improvement is necessary. Especially to increase girl`s and middle schoolers` achievement of science-related affective domain science teaching should consider affective domain of science education.

Most of conventional ultrasonic probes are constructed to generate either longitudinal or shear waves, but not combination of both waves. The ultrasonic probe that generates both of the longitudinal and shear waves simultaneously with a single PZT element was investigated. We studied the performance of a PZT element as a function of its rotation angle so that its efficiency is optimized to excite the two waves equally strongly. The results are verified by checking the impedance variation of the element with Finite Element Methods, and checking the wave form by Pulse-Echo test simulation. The validity of the theoretical calculation is verified through experiments.

The purpose of this study was to investigate the effects of Hangamdan(抗癌丹). The clinical study was carried out 320 cases of patients with cancer treated by Hangamdan(抗癌丹) from May 1st 1998 to September 1st 1999. The results were summarized as follows; 1. The effects of improvement in the symptoms with traditional oriental cancer therapy(47.6%) were higher than combined treatment of western and oriental therapy(37.4%). 2. In the analysis of hematology, maintenance and increasing of WBC(86.2%), Hgb(87.2%), Platelet(97.6%) RBC(81.1%) were Observed. In the analyses of tumor marker, maintenance and decreasing of CEA(76%), CA19-9(88.8%), AFP(69.2%) were observed. 3. In the analysis of safety, maintenance and decreasing of AST(93.1%), AL.T(95%), BUN(92.2%), Creatinine(93.6%) were observed. 4. In the analysis of QOL attached by cancer, combined treatment of western and oriental therapy(maintenance and improvement; 91.8%) was higher than traditional oriental cancer therapy(maintenance and improvement; 79.3%) 5. In the analysis of survival in patients with terminal cancer, above 6 months(46.3%), 12 months( 19.2%). 6. In the analysis of antitumor effects, combined treatment of western and oriental therapy(maintenance 71.6% improvement 12.8%) was higher than traditional oriental therapy (maintenance 66.7% improvement 9.5%). 7. In the analysis of curative evaluation, combined treatment of western and oriental therapy(maintenance 40.4% improvement 41.8%) was higher than traditional oriental therapy (maintenance 23.8% improvement 46.1%). 8. In the analysis of IL-12 and IFN-γ attached by cancer, increasing of IL-12(32.3%), IFN-γ(41.5%) were observed. From the above results, it is suggested that Hangamdan has significant effects of antitumor and immune activity, also could be usefully applied for cancer patients by combination with western therapy or alone.

Many changing mankind's thought and recognition have affected our history, it is same that dance has become a new concept-dance art under the concept that experiment of a new formality and change are creation. Dancer's feeling is exposed through dance is a phenomenon of carrier which independently embodies self. Dance is a harmony between time and space and a harmony made by rhythmic movement and dance composition. Dance is an art expressing feeling and some situations intentionally dr not by moving its body. The way of communication has been changed since the introduction of the New Dance. In traditional dance, there was no sharply defined boundary to divide spectators and performers, that is, the object and the subject of communication. With the New Dance, there established modern theatres, which separated performers from spectators. With the New Dance, the dance itself became interpretive activity. The New Dance remodelled the traditional dance and introduced some element of ethnic dance from other countries. For example, the costume became so diversified in the New Dance that the range of expression also became expanded greatly.

토양 시료로부터 선별과정을 거쳐 생전분을 분해시킬 수 있는 amylase를 생산하는 균주를 분리 하였고, 이 균주(K-1)에 대한 행태적·생리적 성질과 클로닝 가능성 그리고 생전분 가수분해 효소제의 특성을 측정한 결과 분리균주(K-1)는 Bacillus brevis K-1으로 동정되었다. 배양일수에 따른 균의 효소 생산을 측정하였을 때 2∼3일간의 배양에서 최대의 효소활성을 나타내었고 조효소의 최적온도는 35℃, 최적 pH 7.0∼7.5, 온도 안정성은 35℃이하 그리고 pH 안정성은 pH 7.5 이상임을 알 수 있었다. 한편, 효소액의 반응산물에 대한 paper chromatography는 glucose와 maltose가 주 반응 산물인 것으로 보아 본 효소는 당화형 amylase계의 효소임을 알 수 있었다. 그리고 균주의 생육조건은 pH 7.0이고 온도는 35℃로 나타났으며 탄소원에 대한 효소생산은 호화전분 또는 glucose나 maltose를 기질로 하였을 때보다 생전분(CLP)을 기질로 하였을 때 효소 생산력이 2∼5배 이상 높았다. 생전분 가수분해 효소 gene의 HindⅢ 단편과 EcoRV 단편은 pHY300 PLK에 클로닝되었 고 E. coli와 B. subtilis(amy-)에서 발현됨을 알 수 있었다. A bacterium which can utilize raw starch as a sole carbon source was isolated and identified as Bacillus brevis K-1 from its physiological, morphological and cultural properties. Optimal conditions to produce raw starch digesting enzyme were 2∼3 days at pH 7.0 and at 35℃. The crude enzyme had an optimum pH of 7.0∼7.5 and an optimum temperature of 35℃. The enzyme was stable at pH range between 7.0 and 12.0 and at temperature below 40℃. The paper chromatography showed that the crude enzyme was saccharifying amylase. HindⅢ and EcoRV fragments of raw starch digesting amylase gene were cloned in the plasmid pHY300PLK which are E. coli-B. subtilis shuttle vector using E. coli and B. subtilis as a host.

AML is the most common type of leukemia in adults. AML(acute myeloid leukaemia) is characterised by a rapid accumulation of abnormal white blood cells in the blood and bone marrow, resulting in severe anemia, and possibly infection, and hemorrhage during the course of the disease. In general the prognosis of patient with relapsed AML is poor. At this time, however, the only potentially curative therapy for relapsed patients is allogeneic BMT(bone marrow transplantation). This clinical study were carried out 1 case of female patient aged 44 with relapsed AML treated by herb medicine. At the time of admission, she complained of mild fever, nausea, vomitting, abdominal pain, anorexia and no sign of bleeding. For the 10 days of admission, she was treated with Oriental-Western medicine and all the symptoms were disappeared. After that, the syptoms were aggravated because of secondary infection. Anyway, above result showed the possibility of Oriental therapy as Supportive Care in AML.
