인권식,최창진,김봉원,손무정,김인탁 圓光大學校 基礎自然科學硏究所 1987 基礎科學硏究誌 Vol.6 No.2

Proteus vulgaris 를 ammonia와 carbon dioxide gas-sensor에 고정시켜 감응도와 재현성이 우수한 요소에 대한 박테리아 전극을 직접 제조하여 pH, 온도, 완충용액, 박테리아의 양, 여러 가지 아미노산 및 무기염류에 대한 영향과 전극의 수명 등에 관하여 조사하였다. 먼저 ammonia-박테리아 전극은 25℃에서 pH 7.4인 0.05M phosphate 완충용액을 사용하였을 때가 최적이었으며, 7.0 ×10 exp (-4) -3.0 ×10 exp (-2)M 내에서 직선을 나타내었고, 이때 감응도는 116.7mV/decade였다. 한편, carbon dioxide-박테리아 전극은 30℃, pH7.0, 0.1M phosphate 완충용액에서 가장 우수한 감응을 보였다. 이 경우는 7.0 ×10 exp (-4) - 5.0 ×10 exp (-2)M 내에서 45.4 - 45.7mV/decade를 나타내었다. 이들 두 전극중에서 carbon deoxide-박테리아 전극을 이용하여 요소를 정량한다면 방해물질들의 방해가 최소화되었다. 실제 임상적 응용에서 분광 광도법과 비교한 결과 실험과정이 간단하고 편리하여 신속하게 많은 양의 시료분석이 가능하다. Bio-electrodes for urea have been constructed by immobilizing the Proteus vulgaris on ammonia and carbon dioxide gas-sensors. The bacteria containing urease convert each molecule of urea into two molecules of ammonia and one molecule of carbon dioxide gas. Ammonia-bacterial electrode based on ammonia gas-sensor has linearity in the range of 7.0 ×10 exp (-4) - 3.0 ×10 exp (-2)M urea in pH 7.4, 0.05M phosphate buffer solution at 25℃. While carbon dioxide-bacterial electrode based on carbon dioxide gas-sensor has linearity in the range of 7.0 ×10 exp (-4) - 5,0 ×10 exp (-2)M urea in pH 7.0, 0.1M phosphate buffer solution at 30℃. These electrodes were investigated for the effects of pH, temperature, buffer solutions, bacterial amounts and interferences, and life time. As the clinical applications, urea in urine was determined by these devices and was compared with spectrophotometric method. As the results, those methods were by far more simple and rapid than these method.

이창수,여상인 仁川敎育大學校 科學敎育硏究所 2004 과학교육논총 Vol.16 No.-

본 연구에서는 초등학교 4학년 과학의 '지층을 찾아서'와 '화석을 찾아서' 단원을 대상으로 놀이를 통한 교수·학습 자료를 개발하고, 실제 수업에 적용하였을 때, 아동들의 과학에 대한 태도와 학업 성취도에 미치는 영향을 조사하고자 한다. 이러한 연구 목적을 위하여 사전 학업성취도 검사를 통해 학업성취수준이 비슷한 인천시에 소재하는 초등학교 4학년 6개 학급을 표집하여 실험집단과 통제 집단으로 무선 배치하였다. 과학에 대한 태도의 변화를 살펴본 결과, 과학 수업에 대한 즐거움, 과학에 대한 취미적 관심에서 유의미한 향상(p<.05)을 나타내었으나, 과학 탐구에 대한 태도, 과학에 대한 태도의 수용에서는 의미 있는 변화를 보이지 않았다. 실험집 단과 비교집단의 과학 학업성취도의 차이를 분석해본 결과, 두 집단이 통계적으로 유의미한 차이(p<.이)가 있는 것으로 나타났다. 따라서 놀이를 통한 '지층과 화석단원 지도가 아동들의 과학성취도에 긍정적인 영향을 준 것으로 볼 수 있다. 연구 결과를 토대로 초등학교 중학년 이상을 대상으로 놀이 형태의 과학 수업에 대한 시사점을 제안하였다. In this paper, the development of teaching and learning materials through plays with regard to 'Searching for Geological Strata' and 'Searching for Fossils' was pursued. Also, the effects upon children's attitudes towards science and learning achievements were studied, when the above-mentioned plays were applied to actual classes. To this purpose, 6 classes of grade four pupils at an elementary school located in Incheon, whose learning achievement levels were similar, identified via a pre-learning achievements test, were sampled. As a result of examining the attitudes towards science, a significant improvement (p<.05) was indicated in the enjoyment of science lessons and leisure interests in science. However, a significant change was not shown in the attitudes towards on science inquiry and the adoption of scientific attitude. As a result of the analysis of difference in science learning achievements in the experiment group and comparison group, there existed a significant difference (p<.01) in a statistical sense. Therefore, teaching of the Chapters of geological strata and fossils through plays gave positive effects upon the scientific achievements of children. Based on these research results, implications on science lesson through plays targeting upper elementary student were suggested.

Blast furnace, by-product of iron industry has widely used as reclamation materials for pavement or harbour construction. The studies which make blast furnace slag use as aggregates for concrete have being actived owing to natural aggregates insufficiency. In order to use air cooled blast furnace slag as a coarse aggregate for concrete which was fixed to 440kg, 400kg, 360kg, 320kg, 280kg, 240kg of cement content were performed. This study is aimed to ascertain the feasibility of utilizing the concreate with crushed slag aggregates and to find specific properties such as slump air content, compresive strength, tensile strength, bending strength. The results of this study are summarised as follows; 1. On the base of 320kg of unit cement weight the strength according to each dry day are similar in the condition of 45% of w/c whereas in the condition of 50% of w/c the strength of 7-days are similar, but the strength of 28-days are different. 2. In the relation of δ25 - c/w, the strength of slag concrete is greater than that of crushed storn concrete in condition of epual c/w except 400kg/㎥. 3. Slag of concrete as aggregate is destoryed with mortar. 4. The relation of δ28 and tensile strength is very good(γ = 0.8), the equation of regression analysis is δt= 0.63+0.00598 × 28. 5. The reation of bend strength and w/c is liner(γ = 0.72) the equation of regression analysis is δb=80-0.69w/c. 6. It must be care to abtain equal workability to natual aggregate concrete because the change of water absorption is greate. The water content of slag concrete is more than that of crushed storn concrete to obtain the same workability. It must be careful to use blast furnace slag as a coarse aggregate for concrete. And after investgating the quality of demended concrete carefully, real mixing work must be done.

천경아,조인호,원규장,이경희,이형우,현명수,이재태,이규보 영남대학교 의과대학 2002 Yeungnam University Journal of Medicine Vol.19 No.2

Purpose; Ga-67 scintigraphy has been used for the evaluation of tumors, especially lymphoma. Recently, Tl-201 and Tc-99m MIBI were also used to tumor imaging. Tl-201 and Tc-99m MIBI had better physiologic characteristics than Ga-67, so we studied 32 biopsy proven lymphoma patients (male 24, female 8, mean age 46 years) with Ga-67, Tl-201 or Tc-99m MIBI and compared the scan findings. Materials and Methods: Twenty-three of 32 patients were injected 74-111 MBq (2-3 mCi) of Tl-201, before chemotherapy and imaged with dual-headed SPECT (Prism 2000, Picker, USA) at 30 minutes after injection. Delayed images were obtained after 3 hr in 8 patients. Twenty seven of 32 patients were injected 740 MBq (20 mCi) of Tc-99m MIBI and imaged at 30 minutes after injection. 111-185 MBq (3-5 mCi) of Ga-67 was injected in 12 patients and imaged at 48 and 72 hours after injection. Twenty eight patients were diagnosed as non-Hodgkin's lymphoma and others were Hodgkin's lymphoma. Results: Twenty patients were positive on Tl-201 scan and 3 patients showed negative findings. One of these 3 patients, Tc-99m MIBI and Ga-67 scan were positive. Twenty two patients were positive on Tc-99m MIBI scan and 5 patients showed negative findings. One of these 5 patients, Tl-201 was positive and 2 were positive on Ga-67 scan. Ten of 12 patients showed positive findings on Ga-67 scan. The sensitivity of these agents were 83.3%, 87.0% and 81.5% for Ga-67, Tl-201 and Tc-99m MIBI, respectively. The sensitivity was highest in Tl-201 scan, but there were no significant differences among three tests. In this study, there was no significant difference of uptake ratios between early and delayed images of Tl-201. Conclusion: Scintigraphy with Tl-201 and Tc-99m MIBI in lymphoma patients have similar sensitivity with Ga-67.
