The aim of this study was to investigate the posttraumatic stress symptoms of violent crime and predictors to the symptoms. For this, we analyzed data of 473 victims registered to the integrated supporting center for violent crime victims who agreed to participate in the study. The results showed that more than 90% of victims experience significant PTSD symptoms, 30% of them were in extreme mental confusion that required medication or hospitalization. There was a significant difference in the severity of sequela according to gender, time since visiting to the center, pre-event adaptation level, and event type. Although the victim experienced more avoidance and hypervigilance symptoms than the family, the psychological distress experienced by the family was not less than that of the victim. Psychological sequela of the events were found to be more severe with more experiences of childhood trauma, lack of ego resilience, low level of perceived social support, strong dissociation tendency, and avoiding coping styles. A result of the stepwise regression analysis, avoidant coping style explained 10.6% of the total variance. Limitations and implications of this study were discussed.

金京禮,金正漢,李華雨,李尙駿 성균관대학교 약학연구소 1990 成均藥硏論文集 Vol.2 No.1

Abstracts-The cells of Candida tropicalis KCCM 32008 were irradiated by UV lamp for 1 hour. After treatment with UV, mutants were isolated. In order to identify dicaboxylic acids produced in the culture medium of isolated mutants, acids were isolated from other organic compounds by solid-phase extraction method. This method made it possible to process many samples from small amounts of culture media with rapidity. Isolated acids were converted to tert. -butyldimethylsilyl derivatives, followed by gas chromatographic analysis. Dicarboxylic acids produced by Candida tropicalis were identified rapidly by computer searching of the retention index library of organic acids. Three mutants, which produce sebacic acid of high purity, were selected among eleven mutants.

We propose the recognition method of hand written numerical formula using the feature distance and the directionality. The proposed method uses the real time concept that is characteristic of on-line hand written character recognition. First, it receives the pixel coordinates of a numerical formula from a tablet. Secondly, it achieves the separation process on the inputed formula. Thirdly, it supplies sequentially one completed mathematical formula unconcerned with notes order. Finally, using the pattern conformity of feature distance and directionality, we recognize a completed mathematical formula. In the experiment using 100 mathematical formulas, the proposed method showed the recognition rate of about 98%

Method: This study ws performed in the 266 male gout outpatients of the CAU medical center, who had serum lipid level test from Apr. 1996 to Aug. 2000. Serum uric acid, total cholesterol, triglyceride, HDL -cholesterol, and LDL-cholesterol level were measured after 12 hours of fasting. The patients with high lipid level were further evaluated into each type of the hyperlipidemia through electrophoresis study, and the test results were compared with that of the non-gout male adults(40∼60yr), and the statistical significance was examined. Results : The gout patients showed high levels of total cholesterol, triglyceride, and LDL-cholesterol. Especially they showed high level of triglyceride and LDL-cholesterol which suggested as the risk factors of atherosclerosis and coronary heart disease, but shoewed low level of HDL -cholesterol. But there were no definite relations between lipid level and other factors auch as age of patient, initial uric acid ;eve; and duration od gout. Conclusion: To evaluate the risk factors of atherosclerotic change of cadriac vascular system in gout patient, screening tests of serum lipid level of the patient seem mandatory.
