A new spectropotometric determination of citric acid was examined using carbonyldiimidazole (CDI) which has been used in petide synthesis. CDI was reacted with citric acid to form yellow acyl-imidazole derivative (λ??443nm) in dichloroethane. This colored reaction was so characteristic with tricarboxylic acid that can be used selective determination of citric acid in common carboxylic acid. As increasing the reaction temperature, the acyl compound was decomposed to produce the substance of which physical property was similar to the hydrolized compound. Citric acied was calibrated in the range of 1-6μg/ml and the extinction coefficient of the acyl-imidazole compound was 28000 in this condition.

Object : This study was conducted as part of the national project to standardize stroke diagnosis in Korean medicine. In this study, we aimed to evaluate the characteristics of acute stroke between heat pattern group and cold pattern group. Methods : We recruited stroke patients from 5 universities(Kyung-Hee University oriental medical center, Kyung-Hee University East-West Neo medical center, Kyungwon university lncheon oriental medical center, Kyungwon university Songpa oriental medical center and DongGuk university llsan oriental medical center) from April, 2007 until February, 2010. We diagnosed them and selected 463 heat pattern patients and 182 cold pattern patients. Results : We find that the risk factor of smoking, alcohol, diet(prefer to meat) are more associated with the heat pattern group. On the other hand, inflammation history in recent 3 months and diet(prefer to sea food) are more associated with the cold pattern group. RBC, Hg, Hct, TG, CK and Cl are more related to the heat pattern group. CPT, total cholesterol and HDL are more related to the cold pattern group. Tae-eum type takes high distribution of the heat pattern group, and So-eum type takes high distribution of the cold pattern group. Conclusions : This study provides evidence that the heat pattern group have more risk factor than the cold pattern group.

조경언,이현수,윤경하 순천향대학교 기초과학연구소 2004 순천향자연과학연구 논문집 Vol.10 No.2

This study was performed to examine the effect of inducer on laccase production of Pycnoporus cinnabarinus SCH-3 isolated from Korea. The different inducers including 2,5-xylidine were added in the culture of Pycnoporus cinnabarinus SCH-r respectively. 2,5xylidine was predominant of the inducers tested in laccase production. Addition of 2,5-xylidine enhanced 12-fold laccase production, While nothing of inducers produced isoenzyme of laccase, as determined by non-denaturing polyacrylamide gel electrophoresis.

유압 윈치 CLD시스템의 제어

조중선,정경욱 國立 昌原大學校 産業技術硏究所 1995 産技硏論文集 Vol.9 No.-

Control of an electro-hydraulic servo-controlled winch system which has no distinct performance specifications is investigated in this paper. Because of the lack of the performance specification, the research is focused to finding effective parameters which give clear physical meanings for the behavior of the system. Two new parameters named "settling rotation angle" and "settling safety ratio" are proposed for the control of general winch system. The physical meanings of the two parameters are explained precisely. Performance specifications for the target winch system are derived by using the proposed two parameters and a controller is designed to meet the performance specifications. Simulation results show that the designed controller gives responses which can be accepted for the target winch system. The concepts of the new design parameters proposed in this paper can be applied to any kind of servo-controlled winch systems.

헬륨 마이크로파 플라즈마 토치의 개발과 특성에 관한 연구

曺競鉉,朴勇男 한국교원대학교 환경과학연구소 2002 환경연구논문집 Vol.- No.7

MPT는 최근에 개발된 마이크로파 플라즈마로서 수용매에 강하다. 여러 가지의 변형된 형태의 MPT를 개발하여 구조에 따른 플라즈마의 방전되는 형태를 조사한 결과 이중관 토치는 플라즈마 기체를 적게 소모하며 쉽게 플라즈마가 형성되었으나 토치의 끝이 높은 온도에 견디지 못하고 쉽게 상했다. ICP토치와 같은 형태의 삼중관 토치에 석영관을 중심관으로 사용할 때 가장 안정되고 대칭적인 플라즈마를 형성할 수 있었다. 바탕선을 조사해 본 결과 He MPT는 대기 중으로 돌출되어 대기와 많이 혼합되고 질소에 의해 quenching되는 것으로 보여진다. Membrane desolvator를 탈용매화 장치로 사용하여 헬륨 MPT의 감도를 조사해 본 결과 아르곤 MPT와 비교할 때 대부분의 원소에 대해 검출한계가 10배 이상 높았다. 그러나 여기 에너지가 높은 원소는 비교적 효율적으로 검출할 수 있었다. 헬륨 마이크로파 플라즈마는 적은 양의 플라즈마 기체만 필요하여(약 1.6L/min)경제적이며 매우 안정된 형태를 보여주었다. 플라즈마의 분광특성을 조사한 결과 들뜸온도 4950K, 전자밀도 3.28×10^14㎝^-3로 측정되었다. MPT, which has been developed recently, is very tolerant to aqueous samples. Several types of MPT have been investigated and is found that the double concentric tube could sustain a stable plasma at a low plasma gas flow rate. However, the tip of torch is easily ruined. Triple concentric torch has shown the best stability and the plasma shape, much like that of ICP, especially when the central channel is quartz. The plasma is exposed and mixed with air is suggested from the background spectrum, which leads to quenching of He MPT. Sensitivity of helium MPT equipped with a membrane desolvator has shown 10 times lower than that of Argon MPT for most of elements except for the ones with relatively high excitation energy. He MPT requires small plasma flow rate(about 1.6L/min), stable and simple to use. Excitational temperature and electron number density measured are 4950 K and 3.28×10^14㎝^-3, respectively.

The following results were obtained from the experiment to determine the effect of solvent to indicator sensitivity. (1) Non-water-soluble sample does not apply to the Kolthoff theory. (2) Methanol can not be used as solvent in neutralization titration with phenolphthalein indicator. (3) Te reduce error to the maximum degree, ethanol should be used as solvent at the minimum amount. (4) Alcohol interferes with the dissociation of phenolphthatein. (5) For the detemination of Aspirin, it is advised that alcohol should not be used as solvent.

The research aims at how a group art therapy, which integrates motivation intensified counseling theory influences vocational rehabilitation. The object of study is academic background, gender and age-considered random sample of twenty people with mental disability who are getting society adaptation training in a halfway house. In order to minimize entropy and selecting variables K-WAIS, an intelligence test and a simple psychognosis as an examination of symptom were performed, and then through T-test, twenty people are divided into an experiment group and a comparison group. This research was proceeded from January 2 to February 27, 2008, twice a week, There were fifteen sessions, and each session consists of forty minutes of art activity and twenty minutes of feedback. This study follows the theory process of motivation intensified counseling, and refers to motivation of change analysis and effect of motivation improvement program, however the researcher reorganized media and activities according to programs for the purpose of study. In conclusion, the motivation intensified art therapy targeting persons with mental disability improves their job search efficacy, self-efficacy, and job preparation function, and has a positive effect on their vocational rehabilitation.
