피페리딘 디티오카바메이트의 구리(II)의 착물합성과 분석적 응용
김찬우,김창수,Kim, Chan-Woo,Kim, Chang-Su 한국분석과학회 1999 분석과학 Vol.12 No.1
구리(II)이온과 피페리딘 디티오카바메이트(Pipdtc)의 반응에서[$Cu(Pipdtc)_2$]를 합성하였다. 이 착물은 디메틸포름아미드, 디메틸술폭시드의 극성 유기용매에 잘 녹는다. 원소분석, 몰전도도, 적외선 흡수스펙트럼, 전자흡수스펙트럼 및 핵자기공명스펙트럼에서 부터 평면 사각형의 구조를 가짐을 알 수 있었다. 수용액에서 부터 사염화탄소에 의한 Cu(II)-Pipdtc착물의 추출은 pH가 6.0~10범위에서 이루어졌다. 구리(II)의 피페리딘 디티오카바메이트 용액은 pH 9.0에서 ${\sim}8.0{\times}10^{-5}M$까지 Beer의 법칙에 따랐다. Copper(II) complex of piperidine dithiocarbamate (Pipdtc) was synthesized from the reaction of Cu(II) and piperidine dithiocarbamate. The possible structure of the complex was proposed on the basis of elemental analysis, molar conductivity, infrared spectroscopy, electronic absorption spectroscopy, and $^{13}C-NMR$ studies. The extraction of copper(II)-Pipdtc complex by carbon tetrachloride can be achieved in the pH range of 6.0~10. The solution of copper(II) with piperidine dithiocarbamate was bey Beer's law in the concentration up to ${\sim}8.0{\times}10^{-5}M$ at pH 9.0.

Ethionine 및 Methionine 投與가 急性鐵中毒에 미치는 影響에 關한 硏究
金燦于 慶北大學校 醫科大學 1968 慶北醫大誌 Vol.9 No.2
Author studied histopathological changes in various organs of rabbits induced acute iron intoxication with 0.8gm per ㎏ orally and the effects of pretreatment with ethionine and/or methionine on the above changes. The ethionine (200 ㎎/㎏) and methionine (1 gm/㎏) were devided into four doses and given intraperitoneally every the other day prior to the iron administration. The results were as follows: 1) The most characteristic histopathologic lesions in the liver were zonal necrosis, fatty change and parenchymal hemorrhage. These lesions were most severe in ethionine pretreated group, and the severity was lessened in ethionine and methionine pretreated group, control group and methionine pretreated group in order. The necrotic changes, in ethionine, and ethionine and methionine pretreated groups, were prominent both in central and peripheral portion of lobules, whereas in control group the changes were marked in peripheral zone. Such retrograde changes, in ethionine, and ethionine and methionine pretreated groups, were prominent both in central and peripheral portion of lobules, whereas in control group the changes were marked in peripheral zone. Such retrograde changes of the liver were most severe in the animals of 6 to 24 hours after iron intoxication, but the changes were lessened in the animals of 2 days after intoxication, and quite minimal after a week. The iron reaction of the liver tissues was mildly positive in animals of 6 to 24 hours of all experimental groups, but the reaction was not observed later on. 2) Major histopathologic lesions in the spleen were congestion and fibrosis. The congestion was tended to be marked in early experimental period while the fibrosis was in later period. And the iron reaction was moderately positive in early experimental period, but the degree of positivity was declined with time. 3) Histopathologic lesions in the gastro-intestinal tract were congestion, edema and hemorrhagic necrosis of the gastric mucosa. Such findings were most severe in the animals of 6 to 24 hours after iron intoxication, but the changes were lessened in the animals of 2 days after intoxication and not noted after a week. The iron reaction in the mucosal surface also showed strong positive in the animals of 6 to 24 hours after iron intoxication but negative in the animals after a week. 4) The testis showed mild atrophic changes in a few cases of control and ethionine pretreated groups. 5) The other organs such as lungs, pancreas, kidneys, salivery glands and adrenals showed acute congestion only in cases of 6 to 24 hours after intoxication, and no other particular changes were noted.

Plasma Enhanced CVD 법으로 증착한 BON박막과 Si-DLC 박막의 산화
김찬우,홍리석,이동복 한국표면공학회 2007 한국표면공학회 학술발표회 초록집 Vol.2007 No.-
Amorphous BON and Si-DLC thin films were synthesized by the RF plasma enhanced CVD method, and their oxidation behavior was studied up to 500°C in air. The oxidation of both films was accompanied by evaporation of volatile species. The oxidation of BON film was preceded by nitrogen escape from the film, and oxygen penetration into the film. The oxidation of Si-DLC film was preceded by carbon escape probably as CO or CO₂from the film, and oxygen penetration into the film. The inwardly transported oxygen simply stayed in the oxidized BON and Si-DLC thin films.

金讚宇,金昌洙 대구대학교 기초과학연구소 1997 基礎科學硏究 Vol.14 No.1
[Hg(A)₂](A=diethanolaminedithiocarbamate), [Hg₂(B)(ClO₄)₂](B=bis(2-hydroxyethyl) ethylenediaminebis(dithiocarbamate), and [Hg(C)ClO₄]₂(C=N,N'-dimethylethylenediamine야-kthiocarbamate) have been prepared. [Hg(B)(ClO₄)₂] and [Hg(C)ClO₄]₂ are dissolved in water but [Hg(A)₂ not in water. The new mercury(II) complexes have been characterized by conductivity measurements and infrared and UV-visible spectrum studies. The possible structure of the mercury(II) complexes were proposed on the basis of spectroscopic results.

金燦友,崔祐榮 明知大學校 産業技術硏究所 2003 産業技術硏究所論文集 Vol.22 No.-
Abstract - In this paper, an algorithm is perposed a method of display that OpenGL using script. Script is a basic rule easy to analysis and conclusion about command which is able to use. also, it is processed analysis of command and preprocessing for convert OpenGL function by analysis of using script. At first, a step of preprocessing got rid of character without necessity to analysis, and a step of command has made it possible for value of argument with necessity after analysis that OpenGL function is in existence. OpenGL idea of using script which is suggested this paper is expected to give many assistance by using OpenGL user without knowledge about programing.
