마늘이 白鼠의 水銀中毒에 미치는 影響에 關한 硏究

朴在純,車喆煥 고려대학교 의과대학 1984 고려대 의대 잡지 Vol.21 No.3

The garlic which is consumed as a daily spice in Korea contains abundant amounts of thiol compounds such as SH and S-S radicals. These compounds have been though to be involved in the detoxification mechanism of heavy metal poison by the formation of thiochelate compounds when reacting with heavy metals in living body. As part of an examination of this hypothesis, the effect of garlic on the detoxification mechanism of alkyl mercury poisoning in rats was studied. The experimental rats were fed 6ppm of phenyl mercury in potable water in addition to 3 different concentrations of garlic in pellets (1.70%, 3.35%, and 6.70%) which was compared with the control(no mercury and garlic) and the "garlic only" fed group (no mercury). After rearing for 12 weeks with the above prescription, alkaline phosphatase activities in the blood and the accumulation of total mercury in the tissues of target of the brain, liver and kidney were measured. To derive objective clues, additionally, histopathological changes in the tissues of the above organs were observed histologically. As the result, it was found that components of garlic have some roles in detoxificating phenyl mercury poisoning such as decreasing alkaline phosphatase activity, increasing concentration of mercury in target organs, and inducing pathological damages to the organs.

사과를 加害하는 응애類 個體群 動態에 關한 硏究

玄在善,李順遠 서울大學校 農科大學 1985 서울대농학연구지 Vol.10 No.1

1982∼1984年 걸쳐 殺蟲劑와 殺비劑의 處理 및 地面雜草 管理를 달리 하면서, 食植性 응애類의 發生 및 密度變動과 이들의 主要天敵인 捕食性 응애類의 種類 및 活動狀況을 調査하여 다음과 같이 結果를 얻었다. 1. 사과응애는 5月부터 出現하여 7∼8月에 最高 密度에 達하고 以後 10月까지도 發生하였으나, 殺비劑撒布下에서는 대체로 年中 密度가 낮게 維推되었다. 2. 점박이응에는 前年度 越冬密度가 높을 경우에는 5月부터 樹上에 出現하고, 越冬密度가 거의 없을 경우에는 7月 以後에 近接한 棲息處에서 分散·移動하였고, 7∼8月에 급격히 密度가 增加되며, 9∼10月에도 繼續높은 密度를 維持하였다. 또한 殺비劑 處理後 密度回復이 일어나서 處理前보다 휠씬 높은 密度로 增加하는 傾向이 있었다. 3. 殺비劑를 地面撒布하거나 淸耕栽培를 하는 것이 本 試驗區 狀況下에서는 점박이응애의 樹上密度 抑制에 큰 影響을 주지 못하였으며, 捕食性 응애類에 대해서는 오히려 減少시키는 影響이 있었다. 4. 捕食性 응애로 Amblyseius longispinosus(Evans)와 Agistemus terminalis(Quayle) 두種이 發見되었으며 前者는 韓國에서 새로이 發見되었으며, A. longispinosus는 점박이응애에 좀더 效果的인 捕食응애였으나 環境條作에 따라 發生量에 큰 差異가 있었고, A. terminalis는 捕食效果는 낮은 반면에 比較的 安定된 發生相을 나타내어 今後 이들에 대한 評價가 要求된다. The purpose of this study was to examine the seasonal population dynamics of the two phytophagous mites ; two-spotted spider mite. Tetranychus urticae Koch, and European red mite, Panonychus ulmi (Koch), and to evaluate their predaceous mites in the apple orchard. The European red mite seemed to be minor pest, and it seemed to be effectively controlled by the acaricide application. But, the two-spotted spider mite seemed to be the most serious pest. Its density became high enough to require some control measures by middle or late July. There seemed to be common phenomenon of resurgence to the acaricide application in this mite, therefore its density gets the position of economic injury level in short time after treatment. The two-spotted spider mite also feeds on various broad leaf weeds growing under the apple tree in the spring, and later moves to apple tree when the nutritional conditions of the host and other cultural environments become unfavorable. Therefore, the population dynamics not only in the tree but also on the ground cover were important for effective control of the two-spotted spider mites. Two predaceous mites were found ; Amblyseius longispinosus (Evans), and Agistemus terminalis(Quayle). A. longispinosus was effective biological control agent to the two-spotted spider mite, but its density was highly variable with the management system from one plot to another, and from year to year. The density of A. terminalis was considerably high except on the pesticides treated plots, and seemed to be effective predator for the phytophagous mites after August.

環境條件이 다른 두 湖水에 있어서 植物成 Plankton 群集의 特性에 關한 硏究 : II. 植物性 Plankton 群集의 種構性 變動 Ⅱ. Seasonal changes in phytoplankton

黃淳珍,玄在善 서울大學校 農科大學 1986 서울대농학연구지 Vol.11 No.1

A study was made to examine some of the community characteristics of phytoplankton in two reservoirs, having different environmental conditions, on the outskirts of Suwon city, Kyonggi province. Monthly samples were taken from September, 1984, to August 1985, using Kemmlerer, except December, 1984. Total identified species of phytoplankton were 142 in 66 genera, and the numbers of species were 96 in 52 genera for Ilweol reservoir, and 117 species in 60 genera for Ucheon reservoir. The average densities of the phytoplankton were much greater in Ilweol reservoir than in Ucheon reservoir, and the differences were greater at the time of blooms. The blooms of phytoplankton were in May, July and September for Ilweol reservoir while they were in April, July and September for Ucheon reservoir. The dominant taxonomic groups were Oscillatoria, Anabaena, Microcystis, Merismopedia, Scenedesmus. Micractinium, Ankistrodesmus, Golenkinia and Cyclotela for Ilweol Reservoir. While they were Synedra, Fragilaria, Tabellaria, Staurastrum Characium, Pleurotaenium, Asterococcus, Chlorella, and Oscillatoria for Ucheon reservoir, depending on the Seasons. The dominance indices of phytoplankton were greater throughout the year at Ilweol reservoir, while species diversity components, Shanno-Weaver, evenness, and variety indices, were greater in Ucheon reservoir. From the results of the biological indicators in the phytoplankton species, Ilweol reservoir seemed to be already eutrophicated and Ucheon reservoir seemed to be on the way to the mesotrophic state.

임재항,강순민,공영태,최병순,남정희 한국과학교육학회 2004 한국과학교육학회지 Vol.24 No.6

이 연구의 목적은 STS에 대해서 우리 나라 고등학생들이 가지는 견해를 알아보기 위한 평가도구인 HS-VOSTS(Korean students' views on STS)를 개발하는 것이다. HS-VOSIS문항을 개발하기 위해서 다음과 같은 연구과 정을 수행하였다. 우선, 문헌과 선행 연구 고찰을 통해 4가지 범주의 10가지 하위 범주와 관련하여 23개의 논제를 포함하는 STS 범주 체계를 설정하였다. STS 범주 체계는 정의ㆍ과학의 외적 사회학ㆍ과학의 내적 사회학ㆍ인식론의 네 가지의 커다란 범주로 구성되어 있다. 다음은 91f 범주 체계를 기초로 4단계에 걸쳐 문항을 개발하였다. 1단계에서는 각 논제에 대한 짝진술문을 기초로 학생진술 문항지를 작성하여 772명의 고등학생들(16.3세)에게 투입하였다. 2단계에서는 짝진술문 중 하나를 제거하여 문항의 진술문으로 하고, 분류된 공통견해를 답지로 하여 1차 다지선다형 문항지를 구성하였다 3단계에서는 고등학생 28명(16.5세)을 대상으로 반구조화 면담을 실시하여 그 결과 분석을 통해 2차 다지선다형 문항지를 구성하였다. 4단계에서는 2차 다지선다형 문항지를 고등학생 306명에게 적용하여 낮은 반응비율을 보인 답지들을 제거하여 최종 검사도구를 완성하였다. HS-VOSTS는 학생들의 STS에 대한 신념 및 견해를 알아볼 수 있는 유용한 도구로서, 그 결과는 교사뿐만 아니라 교육과정 개발자, 교과서 저자, 교육정책 입안자들에게 많은 시사점을 줄 수 있을 것이라 생각한다. The purpose of this study was to develop HS-VOSTS(High School Students' Views On Science-Technology-Society), which is an instrument that monitors high school students' views on STS. For this study, 23 multiple-choice items were developed on four categories. First, a categorial scheme was constructed. The categorial scheme was based on many instruments that evaluate students' understanding on STS, literature review, and STS learning goal that many researchers had asserted. Second, the multiple-choice items were developed. The development of the items was carried out through four steps. In the first step, some pairs of statement on each subordinate category were formed. Next, the student statement questionaries which were based on the pairs of statement were responded by 772 students. In the second step, the response written by the students were analyzed to common viewpoints and the first multiple-choice items were constructed. In the third step, the semistructured interview with 28 high school students was implemented and the second multiple-choice items were constructed. In the fourth step, the final version of the instrument was developed through the analysis of the students' response on the second multiple-choice items. HS-VOSTS is an useful instrument for monitoring students' beliefs and viewpoints on STS topics. The results of the students' responses to HS-VOSTS items reflect the students' own thoughts directly. These results will give some implications for the curriculum developers, the authors of text books and the educational policy makers as well as the teachers.

鄭瑢載,姜順子,金甲英 이화여자대학교 생명과학연구소 1990 생명과학연구논문집 Vol.1 No.-

한국인 집단의 태반조직과 혈액 내에서의 Malate dehydrogenase(MDH), Lactate dehydrogenase(LDH) alc Glucose phosphate isomerase(GPI)에 대한 다형현상을 알아 보고자 horizontal starchgel 전기영동법을 이용하여 조사한 결과는 다음과 같다. 1. MDH 동위 효소는 혈액에서는 , 한가지 표현형, HDHs1이 나타났으며, 태반에서는 SolubleMDH와 Mitochondial-MDH의 두 form이 모두 나타나는데 태반조직의 MDHs locus에서는 MDHs1 유형만이 나타났고 MDHs locus에서도 보편적 유형인MDHm1 표현형이 나타났다. 2. LDH 동위 효소는 표현형이 혈액에서 normal LDH isozyme인 LDH1, LDH2, LDH3, isozyme이 나타났고, 태반에서는 LDH1(LDHB4) isozyme 한가지 유형만 나타났다. 3. GPI 동위 효소는 혈액과 태반에서 표현형이 모두 같은 형인 GPI1으로 나타났으며 변이형은 한국인 집단에서 발견되지 않았다. 4. 따라서 한국인 집단의 혈액과 태반에서 MDH, LDH, GPI 효소는 모두 monomorphic한 것으로 나타났으나 LDH의 경우만은 혈액과 태반에서 검출된 isozyme의 종류가 상이하였다. Genetic polymorphisms of three placental and blood cell enzymes malate dehydrogenase(MDH),lactate dehydrogenase(LDH) and glucose phosphate isomerase(GPI) in Korean population was studied by starch gel electrophoresis. The results obtained were as follows: 1. MDH phenotype was found to be only MDHs 1 in blood cells. Both of MDHs and MDHm were found in the placental. Only MDHs 1 was found at the MDHs I locus. 2. LDH phenotype was found to be the normal LDH isozyme-LDH1, LDH2 and LDH3 isozyme in blood cells. And DH1(LDHB4) isozyme was found only in the placental extracts. 3. GPI phenotype was found to be only GPI 1 in blood cells and the placental extracts, and no variant type was ound in Korean population. 4. Based on the above results, MDH, LDH and GPI isozymes are monomorphic in blood cells and placental extracts of Korean population.
