A comparative study on the oxidation-reduction and acid-base reaction in thirteen high school chemistry textbook was done. Bronsted-Lowrey conception and Lewis conception in acid-base, and electronic and oxidation number conception in oxidation-reduction are more important, so that the autor would like to emphasize that they should be treated in focus. Laboratory experiments are short in general except CHEM study.

A Comparative study on the electronic configuration and the fundamental concetipons of atomes, and the methods of isolation, involved in twelve current chemistry textbook in high schools were done. Almost all textbooks except CHEM Study did not deal with the orbital conceptions, and the priciples and experiments of isolation were not parareled in general. Relatively simple and new methods of isolation, paper partition chromatography and thin layer chromatography, were in short or nothing at all in advance.
TLC 검출의 適用硏究 : 環境科學 敎材硏究 A Teaching Material of Environmental Science
尹世重 공주대학교 사범대학 과학교육연구소 1977 과학교육연구 Vol.9 No.1
微量成分을 分離하고 確認하는데 여러가지 方法이 있지만, 그 중에서도 學生實驗敎材로 적합한 것으로는 chromatography를 들 수 있다. 특히 paper partition chromatography와 thin layer chromatography(TLC)는 실험이 간편하고 活用범위가 넓고, 많은 학생들에게 일일히 실험 시킬 수 있고, 時間을 유효하게 활용할 수 있고, 또 費用이 많이 들지 않기 때문에 널리 활용될 수 있는 方法이다. TLC는 paper partition chromatography와 거이 같은 내용의 조작을 하면서도, 전展開시간이 짧고 分離가 선명하게 잘 된다는 利點이 있다. 짧은 시간에 많은 학생이 하는 實驗敎材로 아주 훌륭하다. 이 實驗은 TLC를 활용하여, 微量으로도 生理的으로 活性인 alkaloid, caffeine에 대하여 여러가지 溶媒에 따라 Rf값을 측정하여 용매와 試料사이의 상관관계를 알아보고, 각종醫藥品과 市販되는 飮料水에서 caffeine 성분을 檢出해 내는데 適用시켜 보았다. 이를 통하여 TLC 적용의 技術뿐만 아니라, 溶媒의 極性에 따르는 시료의 分配原理를 익힐 수 있도록 시도해 보았다. Thin Layer Chromatography(TLC) is an excellent method for detection and separation of trace amounts of component. Because of shorter running time, clear detection, versatile application, and inexpensiveness, it can be available for non-major students experiment in college and for major students as well. In this experiments, the Rf values were measured when run with various solvents and observed the relationship on the partition of samples against solvents. Caffeine was detected from several drugs and commercial of samples against solvents. Caffeine was detected from several drugs and commercial soft drinks. This would be a base for detection of other biological active pollutants as well as an alkaloid. The Rf value of caffeine was largest in solvent which has a intermediary polarity such as chloroform, and was smallest in solvent which has either larger polarity or nothing such as ethanol or cyclohexane. The best solvent for detection of caffeine from samples was a mixed solvent, chloroform-ethylacetate 1:1 by volume.
Phage Ghost로 破裂시킨 E. coli 에서 Glucose-6-phosphate Dehydrogenase의 活性度 測定
윤세중,Yun, Se-Joong 대한화학회 1968 대한화학회지 Vol.12 No.4
The relative activity of glucose-6-phosphate dehydrogenase in E. coli was measured at 340 $m\mu$ with a spectrophotometer. The synchronized E. coli cells in exponential phase were treated with Phage($T_2$) ghost, and used as a enzyme solution directly. This assay method supposed to be useful for the continuous determination of enzyme activity in E. coli.
美國大學에서의 環境科學(環境硏究) 敎育의 現況分析과 適用
尹世重 공주대학교 사범대학 과학교육연구소 1982 과학교육연구 Vol.14 No.1
Contemporary education of environmtal study in the university of the United StStates was survayed. More than half of the sample universities have established the major or minor system on it. The author suggests that appropriate courses on environmental study should be provided at universities and be elected the course more than eighteen credits by students who are interested to be an environmental specialist.
종합병원 간호사의 직무만족이 감정노동과 환자 및 내원객 응대수준에 미치는 영향
윤세중 중앙대학교 의과대학 간호학과 간호과학연구소 2011 중앙간호논문집 Vol.15 No.-
Purpose: This study was conducted to examine the relations among job satisfaction, emotional labor, and response level of patients of general hospital nurses and to investigate the affecting factors on their job satisfaction. Method: This study was surveyed with structured questionnaires for 450 nurses working at three general hospitals in Seoul from June 12 to 23, 2011. Total 338 questionnaires were used for analysis excluding 12 questionnaires, which showed insincere responses. Data were analyzed using the SPSS 14.0 statistics package with frequency analysis, reliability analysis, t-test, ANOVA, and regression analysis. Results: In ths study, emotional labor and response level of patient among nurses working at general hospitals had a significant influence on their job satisfaction. Job satisfaction was positively correlated with response to patient. There was a significant negative correlation between job satisfaction and emotional labor, and also between response level of patient and emotional labor. Therefore, the systemic management of job satisfaciton and emotional labor have to be developed to encourage higher job satisfaction, and considered difference according to nurses' age and career experiences.
