In order to screen the new β-lactam antibiotics for clinical use. we were compared MIC values of various β-lactam antibiotics. We also tested the influence of pH, inoculum size, stability of antibiotics in medium and some kinds of media on MIC value. As a result, cefotaxime, cefoperazone, piperacillin, cefamandole, cephaloridine, cephapirin, cefazolin, cephalothin, cephaioylycn were scored in antimicrobial activity of MIC data.

홍원표,양현수,장자순,김철규 忠南大學校 産業技術硏究所 1988 산업기술연구논문집 Vol.3 No.2

Terminally functionalized molecules are essential building block for the formation of polymers by polycondensation reactions. It is the major goal of this research to establish new routes for the preparation of such molecules by selective oxidation reaction of cyclohexene, using ozone as an oxydizing agent. To this purpose, it has been explored, whether the usual course of the ozonolysis of olefins can be modified with the help of specific catalyst in order to introduce the desired functional groups. In particular, the ozonolysis of cyclohexene in hydrocarbon solvents and in the presence of pyridine has been tested with the goal of preparing molecules containing one aldehyde and one carboxylic acid group. Ozonolysis of cyclohexene in hydrocarbon solvents such as methylene chloride and pentane can be guided by catalysis with pyridine, such that the reactions afford desired molecules. In this manner, pyridine catalized ozone oxidation converted cyclohexene into the corresponding 6-oxohexanoic acid(45.87%), adipaldehyde(14.68%), and polymeric ozonide(39.45%), via the ω-formyl carbonyl oxides in CH₂Cl₂at 0℃.

Endometriosis is the abnormal growth of endometrial tissue outside the uterine cavity. Endometriosis in the abdominal scar following cesarean section is very rare condition among the extrapelvic endometriosis. The frequency of abdominal wall endometriosis secondary to cesarean section is from 0.03% to 0.8% in some reports. It is difficult to diagnosed in spite of the typical symptoms. The typical symptom is aching swelling in the area of the surgical scar, which is influenced by the phases of menstruation. The definitive diagnosis is established by pathologic analysis. Surgical excision remains the treatment of choice. The majority of patients presented from 1 to 2 years after the precipitating operation. We experienced an unusual case of abdominal wall endometriosis presented over 10 years after cesarean section, who was admitted to our hospital complaining of recurrent left lower abdominal pain. So, we report this case with a brief review of the concerned literatures.

초음파 공명 분광법(RUS)을 이용한 SiC 입자강화 Al 기지복합재료의 탄성계수 해석

홍순형,주영상,정용무,정현규 韓國非破壞檢査學會 1999 한국비파괴검사학회지 Vol.19 No.3

SiC 입자강화 2124Al 금속복합재료의 강화재 부피분율에 따른 탄성 stiffness를 초음파 공명 스펙트로스코피(resonant ultrasound spectroscopy: RUS) 방법을 이용하여 측정하였다. RUS 방법은 한 개의 소형 시편으로 9개의 독립변수를 가진 사방정계(orthorhombic) 탄성계수를 간단한 실험으로 측정가능함을 보여주었다. SiC 강화재 부피분율 변화에 따른 탄성계수를 측정하였는데 이 경우 초기 추정 탄성계수를 구하기 위해서 부피분율에 따른 미세조직 사진으로부터 강화재의 형상(aspect ratio)과 방향을 고려한 유효 aspect ratio 개념을 도입하였고, Mori-Tanaka 이론식에 의한 계산결과를 이용하였다. 이로부터 계산된 공진주파수와 RUS의 측정 공진주파수 사이를 최소화함으로 정확한 탄성계수를 측정하였다. 측정된 stiffnesses로부터 공학적 탄성계수인 Young's modulus를 계산하였으며, 계산된 Young's modulus와 압출방향으로 인장시험한 Young's modulus를 비교분석하였다. SiC 입자의 부피분율이 증가함에 따라 탄성계수가 증가함을 나타내었고, 탄성 stiffness의 거동은 강화재가 많이 첨가될수록 횡등방성(transversely isotropic) 이 강하게 나타났으며 이것은 압출공정에 의해 강화재 입자의 방향성 재배열에 기인한다. 한편 일정크기 시편에 있어서 기본 공진주파수가 강화재 부피분율에 따라 고주파수 영역으로 이동하는 현상이 관찰되었으며, 이로 부터 비파괴적으로 강화재 부피분율을 예측할 수 있는 가능성을 제시하였다. The dynamic elastic properties of metal matrix composites were investigated by resonant ultrasound spectroscopy(RUS). The composites used in this study consisted of 2124 aluminum alloy reinforced with different concentrations of SiC particles. RUS can determine the nine independent elastic stiffness(C )for the orthorhombic symmetry on a small specimen simultaneously. The elastic constants were determined as a function of the volume fraction. A concept of effective aspect ratio, which combine the aspect ratio and the orientation of reinforcement, was used to calculate the initial moduli from Mori-Tanaka theory for the input of RUS minimization code. Young's moduli can be obtained from the measured stiffnesses. The results show that the elastic stiffness increases with increment of the particle content. The behavior of elastic stiffness indicates that the particle redistribution induced by the extrusion process enlarges the transversely isotropic symmetry as the fraction of reinforced particles increase. This relationship could be used for determination of the volume fractions of reinforcement as a potential tool of nondestructive material characterization.

This study conducted a survey of the improvement and popularization for Korea Rice Cakes, a Korean traditional food, on two hundred women students in five colleges in Seoul, Korea. It was investigated to get the information of the recognition, preference, and consumption patterns for the succession and improvement of Korean Rice Cakes. The results are as follows: 1. A portion of 41.5% among responders knows from three to six kinds of Korean Rice Cakes, and of 28% can make at least one among the kinds of Korean Rice Cakes. 2. A portion of 91% recognizes that Korean Rice Cakes are one of well-nourished food, but of 42% answers that Korean Rice Cakes cannot be replaced with the principle food. Also, there are no significant differences in the recognition of Korean Rice Cakes as the kinds of religions. 3. The frequency of purchase is about one or twice in a month (35.5%). Consumers (36.5%) intend to purchase Korean Rice Cakes for the commemoration of national holidays or anniversaries. 4. The reasons for the preference of other foods more than Korean Rice Cakes are the easiness of purchase (36.0%), the deliciousness (21.5%), the diverse kindness (17.5%), and the proper package (9.5%). It is important that constant and particular school / home education is need to improve and success Korean Rice Cakes.
