The authors has made an investigation on the water pollution of Kum River in chungnam province area from January to December 1981 and discusses the results of the water quality for the water samples were taken from 5 stations along the Kum River basin that is, Caechung dam (Ⅰ), Meapo(Ⅱ), Yeungi(Ⅲ), Gongju(ⅳ) Bueyeu(ⅴ). It is confirmed, by the analysis of B.O.D., C.O.D., S.S. and coliform that the Kum rever water was relatively less polluted than the other. Therefore it may be suitable still as source of water system. The relationships between pollutants in the Kum River Basin are as follow; B.O.D.(㎎/ℓ)=1.30C.O.D.-0.05(㎎/ℓ)

백승화,이수민,오인교 圓光大學校 1981 論文集 Vol.15 No.1
The adsorption of metal ions by chelating agent-loaded resins was studied in aqueous media. The resins were prepared by loading the conventional cation exchange resin, coated glass powder by pohsphonyl atactic polypropylene resin(200 to 250 mesh) with chelating agents containing hydroxyl groups. The composition of synthetic resins was analyzed by infrared absorption spectroscopy and also discussed. The optimum conditions for the adsorption of metal ions were determined with respect to the shaking time, the effect of cation concentration and the effect of adsorption of capacities on the industrial waste water in the medium.

Analysis of substance on the Ethrel(2-chloroethylphosphonic acid) sparyed tomatoes and natural growing tomatoes has been inverstigated. The measured results from this study were as followings; 1. Tomatoes are in buffer state of several organic acid. 2. At green state acidity and reducing sugar contents are increased gradually. 3. At after taken, the reducing sugar is increased rapidly. 4. The contents of vitamin C, glucose, protein in Ethrel sprayed tomatoes are not increased.

An investigation of the water quality for the streams of Daejon area in Chung-nam province, korea, was conducted from January to December 1981. By this analysis of water quality for the streams of Daejon area, annual mean values of BOD: 49.3㎎/l, COD: 33.4㎎/l, DO: 7.5㎎/l, SS: 39.1㎎/l were determined respectively and those values of parameters were comparatively high. The increasing order of the water pollution for the streams of Daejon area was as follows; confluence place Daewha-Dang (D)> Yudeung Stream (B)> Daejon Stream (A)> Gab Stream (C). Therefore, it suggest that the water pollution of the streams of Daejon area have greatly influenced upon the water quality of Kum River in Chungnam and Jon-buk province.
EBT로 처리된 음이온 교환수지에 의한 Fe(Ⅲ), Ca(Ⅱ), Mg(Ⅱ) 및 Ni(Ⅱ)이온의 흡착에 관한 연구
정창웅,오인교,양희태 순천향대학교 1982 논문집 Vol.5 No.4
The adsorption of Fe(Ⅲ), Ca(Ⅱ), Mg(Ⅱ) and Ni(Ⅱ) ions by chelating agent-treated resin was studied in aqueous media. The resin was prepared by the treated conventional anion exchange resin, Dowex l-X8 (50 to 100 mesh) with chelating agent containing sulfonic groups such as Eriochrome Black T(EBT). The stability of the resin was markedly influenced by the pH of the media. The optimum conditions for the adsorption of metal ions were determined in respect to the pH, shaking time and mixture solution of metal ions. Separations of Fe(Ⅲ) and Ca(Ⅱ) from multicomponent solutions of Fe(Ⅲ), Ca (Ⅱ) Mg(Ⅱ) and Ni(Ⅱ) are possible by adjusting the pH of these solutions. The total caoacities of the resins in Fe (Ⅲ) were found 3.99㎛ol/gr in the condition of pH 3.0 and in Ca 3.79㎛ol/gr in the condition of pH. 8.8.

In the present study, we have evaluated cytotoxic effects of Taraxaci herba extract on human skin melanoma cells. The light microscopic study showed morphological changes of the treated cells. Disruptions in cell organelles were determined by calorimetric methods: MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazoliumbromide), NR (Neutral red) and SRB (Sulforhodamine B protein) assay. These results suggest that Taraxaci herba retains a potential antitumor activity.

Compounds 1 - 12 were tested for their growth inhibitory effects against tumor cell lines using two different 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) and sulforhodamine B protein (SRB) assays and antimicrobial activity. The cytotoxic activity of methyl-4[{(2E)-3,7-dimethyl-2,6-octadienyl}oxy]-3-methoxy benzoate (1) exhibit more active than that of 5-fluorouracil (11) on human oral epithelioid carcinoma (KB, ATCC No. OCL 17) cell lines. But this compound (1) on human skin melanoma (SK-MEL-3, HBT 69) cell lines shows less active than that of adriamycin (12). However, compound 9 showed the antimicrobial activity against S. epidermidis (MIC, 15.625 ㎍/㎖), S. aureus, C. albicans (MIC, 31.25 ㎍/㎖), S. mutans, S. typhimurium, P. putida (MIC, 125 ㎍/㎖) and P. aeruginosa (MIC, 500 ㎍/㎖)

o-Chlorobenzylidenemalononitrile(CS), chloroacetophenone 및 bromophenylacetonitrile의 이성질체와 같은 최루 자극성 물질들의 가수분해, 산화, 환원, 열분해 및 대사에 의한 화합물의 분석은 법과학적 측면에서 주요한 의미가 있다. 본 실험에서는 10% MeOH-$H_2O$ 및 10% dioxane-$H_2O$ 용액에서 pH 1.0~11.0과 온도 변화에 따른 CS의 가수분해 조건을 검토하고 가수분해 생성물이 o-chlorobenzaldehyde와 malononitrile임을 분광학적 방법 및 전기화학적 방법에 의해 확인하였다. The analysis, hydrolysis mechanism, oxidation, reduction, thermal decomposition and metabolism of irritant materials such as chloroacetophenone isomers, bromophenylacetonitrile isomers, o-chlorobenzylidenemalononitrile(CS), and ethylisothiocyanate, etc. are interested in forensic science. We had studied hydrolysis of CS in 10% MeOH-$H_2O$ and 10% dioxane-$H_2O$ at pH 1.0~11.0 and various temperatures. As a result, we identified o-chlorobenzaldehyde and malononitrile that were formed by hydrolysis of CS by using gas chromatography/mass spectrometry, UV/Vis spectrometry, and polarographic method.
