과학적 소양을 갖춘 시민 양성이 오늘날 과학교육의 중요한 목적 중의 하나임은 주지의 사실이다. 이를 위한 교육방법의 하나인 STS 교육은 우리나라에서도 그 중요성이 크게 인정되고 있는 형편이다. STS 교육을 활성화하기 위해서는 실제로 우리 나라의 교육 환경 하에서 활용할 수 있는 STS 프로그램, 진행을 위한 안내서 및 기본 자료의 개발이 필요하다. 본 연구에서는 이러한 점들을 고려하여, 학습자들이 교수-학습 활동의 중심이 되며 교사는 조력자로서의 역할을 하는 STS 수업의 실제 상황을 예시하고, 이 과정에서 적용한 교수-학습 방법과 활용한 자료들을 바탕으로 고등학교 지구과학의 지진 분야 학습을 위한 STS 프로그램을 개발하여 제시하여 지구과학 수업에서 STS 교육이 가능하도록 하는데 도움이 되고자 한다. It is a well known fact that it is a one of important objects of science education today to bring up citizens with scientific attainments. As a way to achieve the above object, STS's importance is being highly emphasized. To activate STS education, it is needed to develop STS programs, guide books and fundamental materials. Considering these sectors, this study shall present actual situations of STS education in which students are at the center of teaching and learning process and teachers are assistants. Based on teaching learning methods and material applied in the above process, this study shall help to enable STS in earth science by developing and presenting STS program for earthquake portion in high school earth science.

The dynamic mechanical properties of thermotropic liquid crystalline polyester (LCP) blends with polystyrene (PS) and Li sulfonated polystyrene (PSSLi) were investigated. It was found that PS forms an immiscible blend with LCP. However, above the matrix T_(g) of the PS, the addition of the LCP increases the modulus of the blend significantly because the LCP acts as filler below its T_(g). In PSSLi/LCP blend system, it was also found that, in the temperature range between two T_(g)s of the ionomer, the LCP acts as filler and thus increases the modulus of the blend. However, the filler effect of the LCP on the modulus decreases rapidly with increasing temperature and disappears above the T_(g) of the LCP. Finally, it was suggested that the PSSLi may be partially miscible with the LCP via ion-dipole interactions between a Li^(+) cation of the PSSLi and a carbonyl group of the LCP.

중등학교의 지구과학과 열린 수업을 위한 달과 행성의 위상 변화 프로그램 개발을 주제로 본 연구에서는 철저한 학습 과제 분석을 통하여 개념 위계도를 작성하였으며, 이를 바탕으로 교수-학습의 순서와 방향을 모색하였다. 학습자의 자기 주도적 학습을 통하여 달의 위상 변화를 파악할 수 있도록 하는 ‘달 관측 안내서’를 제작하였다. 또한 달과 행성의 위상이 변하는 원리를 이해하게 하는 실험을 개발하여 제시함으로서 학습자들이 농구공 스케치라는 친숙한 실험 활동을 통하여 빛의 원리와 위상 변화를 관련지어 이해하도록 하였다. 실험의 전개에서 조별 토의 등 협동 학습을 통하여 학습자의 인성 및 사회성을 함양하는데도 관심을 기울였고, 학습자의 수준별 학습을 강조하는 의미에서 학습 주제를 다루는 관련 인터넷 사이트를 소개해 줌으로써 보다 상위 단계로의 학습을 권장하고 학습자의 호기심을 충족시킬 수 있도록 하였다. 또한 수업시간에 사용할 수 있는 프리젠테이션 자료를 개발함으로써 학습자의 학습 활동 및 교사 활동이 보조를 맞추어 진행될 수 있도록 전체 프로그램을 설계하고 개발하였다. With the subject of development of program for teaching-learning of the phases change of the moon and the planets for open education of earth science in secondary school, we searched for the order and direction of teaching-learning based on the concept map that were drawn through learning task analysis. We made "A Guide for Moon Observation" by which learners can understand the phases change of the moon through self-leading learning. By developing and presenting the experiment that explain the principal of the phases change of the moon and the planets, we promoted learners understand the phases change related to the principal of light through drawing basketball. We paid attention to raising personality and sociality of learners through cooperative learning in the process of experiment. And we encouraged higher level learning and let the learners' curiosity satisfied by offering subject-related internet sites. We designed and developed whole program to balance learning and teaching activities by developing presentation materials that can be used in classes.

Antibacterial and Antifungal Activities of a Naphthoquinone Derivative Isolated from the Fruits of Catalpa ovata G. Don

KUK, JU-HEE,MA, SEUNG-JIN,MOON, JAE-HAK,KIM, KIL-YONG,CHOI, SANG-HO,PARK, KEUN-HYUNG 한국미생물 · 생명공학회 2002 Journal of microbiology and biotechnology Vol.12 No.5

An antimicrobial compound was isolated from the MeOH extract of Catalpa ovata G. D_ON fruits, and its structure was identified as 4, 9-dihydroxy-2, 2-dimethyl-3, 4-dihydronaphtho[2, 3-b]pyran-5, 10-dione (HMNP). The antimicrobial activity of the HMNP was determined by measuring the dose-response inhibition of microbial growth in liquid cultures and then compared with that of lapachol, a well known antimicrobial 1, 4-naphthoquinone. The antimicrobial activity of the HMNP was more effective than that of lapachol over a wide range of test organisms. Gram-positive bacteria, yeast, and fungi (IC_50 20-75㎛) were found to be more sensitive to the HMNP than Gram-negative bacteria (IC_50>100㎛). The HMNP also inhibited germination of spores of many fungi. The morphological deformation of the fungal spores was induced by the treatment of HMNP, as illustrated by Scanning Electron Microscopy (SEM).

The aim of the present study was to evaluate the central antinociceptive effects of eugenol after intraperitoneal administration. Experiments were carried out using male Sprague-Dawley rats. Subcutaneous injection of 5% formalin-induced nociceptive behavioral responses was used as the pain model. Subcutaneous injection of 5% formalin significantly produced nociceptive responses by increasing the licking time during nociceptive behavior. Subsequent intraperitoneal injection of 100 mg/kg of eugenol led to a significant decrease in the licking time. However, low dose of eugenol (50 mg/kg) did not affect the nociceptive behavioral responses produced by subcutaneous injection of formalin. Intrathecal injection of 30 μg of naloxone, an opioid receptor antagonist, significantly blocked antinociceptive effects produced by intraperitoneal injection of eugenol. Neither intrathecal injection of methysergide (30 μg), a serotonin receptor antagonist nor phentolamine (30 μg), an α-adrenergic receptor antagonist influenced antinociceptive effects of eugenol, as compared to the vehicle treatment. These results suggest that central opioid pathway participates in mediating the antinociceptive effects of eugenol.

플루메퀸의 분석은 시료를 ethyl acetate로 추출 농축한 후 이 농축액에 acetonitrile과 n-hexane을 가하여 분리하고, 분리된 acetonitrile층을 농축하였다. 이를 이동상에 녹여 여과한 후 C₁? 컬럼을 이용한 HPLC-FLD로 분석하였다. 분석법은 표준물질 0.1-1.0㎎/㎏의 농도범위에서 직선성(r²= 0.9979)을 나타냈으며, 검출한계는 0.005 ㎎/㎏, 정량한계는 0.017 ㎎/㎏이었다. 또한 회수율은 쇠고기에서 90.8-96.7%, 돼지고기에서 96.4-96.6%, 닭고기에서 94.0-101.1%이었으며, 상대표준편차(RSD)는 쇠고기, 돼지고기, 닭고기에서 각각 5.3-8.6%, 3.0-6.8%, 3.1-4.1%이었다. 확립된 분석방법으로 유통 중인 식육(쇠고기, 돼지고기, 닭고기) 150건을 전국지역(서울, 부산, 대구, 대전, 광주)별로 수거하여 플루메퀸의 잔류 실태를 조사한 결과, 쇠고기 1건(0.080 ㎎/㎏), 돼지고기 1건(0.048 ㎎/㎏)에서 검출되었으며, 조사한 식육 150건의 플루메퀸 잔류량은 모두 잔류허용기준 이하의 수준이었다. An analytical method for the determination of flumequine in meats was developed and validated using high-performance liquid chromatography with fluorescence detection. The samples were mixed with sodium sulfate and extracted with ethyl acetate. After clean-up, the residues were dissolved in mobile phase. The calibration curves showed high linearity (r²= 0.9979) within the concentration range of 0.1-1.0 ㎎/㎏. The limit of detection and limit of quantification were validated at 0.005 and 0.017 ㎎/㎏, respectively. The recoveries in fortified meats ranged from 90.8 to 101.1%. The method was then validated in correspondence with the CODEX guidelines for flumequine residue in meats. Herein we monitored 150 samples of meats that were purchased in Korea (Seoul, Busan, Daegu, Daejeon, and Gwangju). Among the tested samples, flumequine was detected in 1 of beef and 1 of pork at levels in the range of 0.048-0.080 ㎎/㎏. Overall, the flumequine residues in the tested samples were within the Maximun residue limit.
