The substitution products of thioglycolic acid to the derivatives of 1-chloro-1-phenyl-2-carboethoxy-e-cyano ethene synthesized 1-Chloro-1-phenyl-2-carboethoxy-2-cyanoethene [Ⅴ], 1-chloro-10(4-chlorophenyl)-2-carboethoxy-2-cyanoethene[Ⅳ] and 1-chloro-1-(4-methoxyphenyl)-2-carboethoxy-2-cyanoethene[Ⅶ] undergo substitution reactions with thioglycolic acid to form s-[(1-phenyl-2-carboethoxy-2-cyano) ethenyl]-thioglycolic acid s-[(1-(4-chlorophenyl)-2-carboethoxy-e-cyano] ethenyl]-thioglycolic acid and s-[1-(4-methoxyphenyl)-2-carboethoxy-2-cyano] ethenyl]-thioglycolic acid, respectively. The structure of products were identified by elemental analysis, potentiometric titration, infrared and nmr spectra.

Purpose: The purpose of this study was to analyze students' expectance demand towards high school physical education teaching. Methords : 392 participants randomly selected from one girls' middle school and one girl's high school in each of five tracts and then selected two classes from each of the schools. They were asked to respond to a simple Questionnaire about their views on the present physical education teaching. Results : Results showed that about one third of the participants would not choose physical education if the program were offered as an optional subject. Both male and female students ranked psychomotor domain as the top priority among the various learning objectives. Male students favored soccer and basketball while their counterparts liked badminton and volleyball. Over three-fourths of the participants suggested that students' opinions should be considered when teachers plan their program. Conclusion : The results of this study recommended that physical education teaching should be designed with considerations for professional values, societal changes as well as students' expectance on the design of physical education.
Riboflavin Tetrabutyrate의 합성에 관한 연구
李英行,李鍾律,李寀浩 圓光大學校 基礎自然科學硏究所 1983 基礎科學硏究誌 Vol.2 No.1
Riboflavin(Vitamin B_2) is a component of two closely related coenzymes, flavin mononucleotide(FMN) and flavin adenine dinucleotide(FAD). Riboflavin tetrabutyrate is more fat-soluble than riboflavin, which is highly absorbed in vivo. and hydrolysed to give riboflavin. Riboflavin tetrabutyrate has always been synthesized by general method of ester. But the use of DMAP was found be very effective for esterification of riboflavin with butyric acid.
새로운 의약품의 합성에 관한 연구 : 6-Thiocyanopenicillanic Acid 유도체의 합성
李英行,李寀浩,崔元植 원광대학교기초자연과학연구소 1992 基礎科學硏究誌 Vol.11 No.3
6-Aminopenicillanic acid의 diazo화 반응과 sodium thiocyanate와 반응으로 새로운 β-lactam 화합물인 6-thiocyanopenicillanic acid(1a)를 합성하고 p-nitrobenzyl bromide, chloromelthylpivalate 및 1-chlorodiethylcarbonate들과의 반응에 의해 각각에 해당하는 ester(1b~d)를 합성하였다. A new β-lactam compound, 6-thiocyanopenicillanic acid(1a) was prepared by the reaction of diawnium salt of 6-aminopenicillanic acid with sodium thiocyanate. Reaction of 6-thiocyanopenicillanic acid(la) with p-nitrobenzyl bromide, chloromethylpivalate and l-chlorodiethylcarbonate, respectively, afforded the corresponding esters(1b~d).

Background : Electrolyzed acid water (EAW) is a new liquid chemical germicide containing a mixture of oxidizing species and prepared by mixing a small amount of salt with tap water in an electrolyzer. We attempted an in-use evaluation of the high-level disinfection capability of Cleantop WM-1□, a new endoscope reprocessing system using EAW. Methods : Forty-seven flexible endoscopes were randomly collected just after upper endoscopic examinations and were disinfected using Cleantop WM-1□. Parts of the endoscopes without contact to EAW were disinfected with 75% ethyl alcohol. Immediately after the disinfection procedure, samples were taken from the biopsy channel (S-1), tip of the insertion tube (S-2), the umbilical cord (S-3), and the angulation knob (S-4). Results : In EAW-disinfected parts of the endoscopes, the culture-positive rates were 4.3% (2/47) in S-1 samples and 12.8% (6/47) in S-2 samples. In ethyl alcohol-disinfected area, the culture-positive rates were 2.1% (1/47) in S-3 samples and 25.5% (12/47) in S-4 samples. The colony counts of culture-positive samples ranged from 1 to 144. Pseudomonas aerugi-nasa was recovered from the angulation knob of an endoscope, but other contaminating organisms were mostly : normal flora or opportunistic pathogens. Conclusion : Although part of the endoscopes disinfected with 75% ethyl alcohol were contaminated with more organisms than EAW-disinfected areas, Cleantop WM-1□ showed a relatively good disinfection efficacy in reprocessing patient-used endoscopes.

Eighteen patients took Moclobemide for 6 weeks, who had been diagnosed as major depression based on DSM-Ⅲ-R and had had more than 16 points on the Hamilton Depression Rating Scale. After medication of Moclobemide, they were evaluated by the Hamilton Depression Rating Scale and in terms of sleep, vigilance, performance, social interactions and drive. The results were as follows ; 1. The average dosage of Moclobemide was 400±89 ㎎. 2. Antidepressant effect were checked on the all items of the Hamilton Depression Rating Scale and prominent on the items of work and activities, insomnia, suicide, somatic symptoms. 3 There were obvious changes of the antidepressive effect by the evaluation of the doctors and patients at 4 weeks after the medication of Moclobemide. 4. In the patients, 61% had positive effects on the sleep. 94% no negative effects on the vigilance. Nobody has negative effects on the social interactions and drive. 5. Side effects or physical disturbances induced by Moclobemide were not found. According to these results, it seemed that Moclobemide had clear antidepressant effects, few negative effects on the life of day time, positive effects on the sleep and somatic symptoms.
N-Isoprophyliminotriphenylphosphorane과 Benzaldehyde 유도체와 반응
李英行,李晩求,金基炫 圓光大學校 基礎自然科學硏究所 1986 基礎科學硏究誌 Vol.5 No.2
The reactions of N- sopropyliminotriphenylphosphorane with benzaldehyde derivatives were investigated by GC. The reaction were completed within 8hours at an approximate reaction condition. The reactivity of benzaldehyde was in order, Ar=p-NO_2>p-Cl>p-Br>H>p-CH_3>p-CH_3O> and Ar=p-C_2H_5O, consistant with the Wittig mechanism. The reactivity of iminophosphorane increased with the change of reaction solvent from benzene to ethanol.
인슐린의존형 당뇨병환자에서 임신중 병발한 당뇨병성 케톤산증 1예

저자등은 인슐린의존형 당뇨병환자에서 임신중에 병발한 당뇨병성 케톤산증을 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. IDDM is an autoimmune disease resulted from beta cell destruction and insulin deficiency, and developed mostly in children and puberty. Ketoaddosis remains one of the most senous complications that can occur in the pregnant diabetic. A 26-year-old woman, gravida 1, para 0, was admitted at 32 weeks gestation because of fever lasted for 6 days. She had been treated with insulin pump during the pregnancy. Blood sugar was well controlled before admission, and the etiology of her ketoacidosis was urinary tract infection and no insulin-intake. DKA was treated with fluids and intravenous insulin. Urinary tract infection was treated with antibiotics, based on culture test. Healthy newbom was later delivered by cesarean section due to fetal distress. We experienced a case of DKA in pregnant woman and report it with a review on literature.
