This bench-scale research investigated the aeration cycle(on/off) as the controlling factors for nitrogen and phosphorus removal in a 2-stage. intermittent aeration process. At this experiment, the aeration cycle time(air-on/air-off) was 30min/30min. 60min/60min, 90min/90min. Organic matter removal was obserred more than 90% regardless of the aeration cycle and phosphorus removal was relatively high when the aeration cycle time was 60min/60min On the other hand. For all of the aeration cycle, TN removal was appeared less than 53% This result was probably due to the limitation of the external substrate for heterotrophic nitrification and aerobic denitrification

강영수,김동인,이선미,김 임,김태형,은헌정 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.4

연구 목적 : 임상가를 위한 외상후스트레스장애 척도를 이용하여 교통 사고 후 신체 손상 환자의 외상후스트레스장애의 발병률을 알아보고, 사회인구학적 변인들, 손상 심각도, 불안, 우울과 외상후스트레스장애와의 상호관련성을 고찰하고자 하였다. 방 법 : 104명의 교통사고 환자들을 대상으로 , 자기 보고형인 사고 후 정신 건강에 관한 설문지와 외상후스트레스장애를 진단하기 위해서 임상가를 위한 외상후스트레스장애 척도를 이용하여 면담을 실시하였으며, 손상 심각도 척도를 이용하여 신체 손상의 정도를 측정하였다. 결 과 : 외상후스트레스장애의 발병률은 61.5%이었으며, 사회인구학적 변인들과 손상 심각도 점수에서는 외상후스트레스장애군과 비 외상후스트레스장애군이 유의한 차이를 나타내지 않았다. 그러나 외상후스트레스장애 군에 속한 사람들이 사고 당시에 사망자나 부상자를 목격한 경우가 의미있게 많았고(χ²=8.48, p<0.05). Beck의 우울점수가 외상후스트레스장애군에서 유의한 증가를 보였다.(t=5.03, p<0.05). 결 론 : 교통사고 후 외상후스트레스장애의 발병률은 매우 높았고, 두 집단 모두가 정상인 보다 훨씬 더 높은 불안과 우울을 보고하고 있다. 이와 함께 연구 결과는 상황에서 사망자와 부상자의 목격시 외상후스트레스장애로 발병하게 하는 위험 요인 중 하나 일 수 있다. Objectives : the authors attempted to estimate the incidence of posttraumatic stress disorder (PTSD) and the differences of sociodemographical feature, injury severity, depression and anxiety between PTSD and non-PTSD groups after motor vehicle accident. Methods : The subjects were 104 patients who had undergone motor vehicle accidents, and been hospitalized to orthopedic surgery hospitals. We administered them clinician-administered PTSD scale(CAPS) for diagnosing PTSD, injury severity scale(ISS) for identifying their physical injury, self-reported questionnaire made to identify socioepidemographic data, Beck Depression Inventory(BDI) for measuring depression, and State Trait Anxiety Inventory Ⅰ,Ⅱ(STAI-Ⅰ,Ⅱ) for measuring anxiety. Results : The incidence of PTSD in subjects was 61.5%. Most of sociodemographic factors were not different between PTSD and non-PTSD groups. Only there were significant differences between PTSD group and non-PTSD group on the cases that observed the dead or the wounded at the scene of motor vehicle accident(χ²=8.478, p<0.05) and BDI(t=5.03, p<0.05). Conclusion : These results indicate that prevalence of PTSD is higher after motor vehicle accident and both of the two groups report much higher depression and anxiety than normal population. In addition, the results of this study show that the observation of dead or wounded at accident situation can be one of risk factors to precipitate PTSD.

In order to investigate the preventive effects of Houttuyniae Herba experimental studies were performed in rats fed 1%-cholesterol + Houttuyniae Herba Ex.. The results were summarized as that : Houttuyniae Herba showed significant inhibition on increase of serum total cholesterol, triglyceride and phospholipid contents as well as remarkable inhibition on decrease of HDL-cholesterol contents in hyperlipidemia-induced rats fed 1%-cholesterol + Houttuyniae Herba Ex. Judging from above results, it is proved that Houttuyniae Herba is applicable to hyper-lipidemia such as hyper-cholesterolemia, hyper-triglyceridemia and so on, causing ischemic heart diease, hypertension, artero-sclerosis and cerebro-vascular accidents.

This research aims to attract patients of AMA(Against Medical Advice). The patients are neglected because they are a few, but the patients are very important for hospital income. So, this study analysis patients of AMA. The analysis items are 1) a course of hospital, 2) health delivery system, 3) whether or not consultant, operation and transfer, 4) principle diagnosis, 5) specialty fields, 6) length of stay, so on. The results show that AMA of male, old, and emergency case is high. In principle diagnosis, AMA of cerebral infaction and fracture and liver disease is high. Therefore it's meaningful research for hospital management.

이차 전기영동을 이용한 프로테오믹 접근을 통한 정맥 압박이 혈장 프로테옴에 미치는 영향

The human proteomics-based approaches, which examine the expressed proteins of a tissue or cell type, are increasingly being used. Venous occlusion is commonly employed for stimulating tissue-plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-l) release from venous endothelial cells, and this has been regarded as a parameter of the individual fibrinolytic capacity of plasma. The present work involved a detailed investigation of the plasma proteome and fibrinolytic activity in normal subjects, with the aim of determining whether correlations exist between various parameters of the fibhnolytic system before and after venous occlusion. We analyzed fibhnolytic parameters and plasma proteome before and after 15-min periods of venous occlusion in the forearm in 10 healthy 3rd-decade volunteers. Proteome analysis was performed using two-dimensional gels. The tryptic digests of some proteins were confirmed by MALDI-TOF and the MS-Fit algorithm. The fibrinolytic response as measured by the absolute amount of t-PA after venous occlusion was increased by venous occlusion (5.5 vs 9.6 ng/㎗, p<0.05), as was PAI-l (46.8 vs 56.1 ng/㎗, p<0.05). However, two-dimensional electrophoresis finding was virtually nonspecific and inconsistent after venous occlusion in healthy male subjects. Venous occlusion does not influence plasma proteome in healthy males. Although the fibhnolytic response to venous occlusion is attributed to an increase in free tUPA antigen, this change is not correlated with plasma proteome.

Thirty children with fracture of shaft of the femur were encountered into retrospective analysis to compare the results between conventional (traction with 90-90 followed by hip spica cast) and operative methods (Ender nail intramedullary nailing and external fixation) especially pointing to residual deformity, shortening, hospitalization and sets of radiographs. Our conclusion for this study is that the most femoral shaft fractures in children over 7 years of age can be treated by closed I-M nailing or external fixator with results that are not better than with conventional method in addition to less shortening, deformity, hospitalization and sets of radiographs taking. Other factors such as comminution, site of fracture, head injury, multiple injury in addition to age of child should be considered to select the method of treatment in femoral shaft fracture in children.

은헌정,이선미,장광철 大韓神經精神醫學會 1994 신경정신의학 Vol.33 No.2

본 연구는 외상후 스트레스 장애와 정상인을 의미있게 구별하여 주는 다면적 인성검사 반응 특성을 확인하고, 외상후 스트레스 장애군 내의 다면적 인성검사 프로화일 특성을 분류하고자 시도하였다. 연수 대상은 1991년 1월부터 1993년 3월까지 전주 예수병원에 입원 또는 외래로 내원한 외상후 스트레서 장애 환자 45명과 정상인 55명을 대상으로 하였다. 결과는 다음과 같다: 1) 외상후 스트레스 장애군이 L척도를 제외한 모든 척도에서 정상집단보다 의미있게 더 높은 점수를 보였다. 2) 판별 분석에서 두 집단을 잘 판별해주는 척도는 D, Mf, Pt,Si척도이고, 이 척도들은 외상후 스트레스 장애군을 88.9% 정확헤게 판별해 주었으며, 정상 대조군은 94.5% 정확하게 판별해주었다. 3) 외상후 스트레스 장애군의 다면적 인성검사 반응을 군집 분석한 결과 3개의 하위 집단이 추출되었다. a. 첫번째 집단은(54.3%) L, F, K척도의 프로화일이 역전된 'V' 형태이고 Hs, D, Hy, Pd , Pt, Sc척도의 점수가 60년에서 71점 사이의 점수를 보이고 있다. b. 두번째 집단은(36%) L, F, K척도의 점수가 47점에서 56점 사이의 범위를 보이고 있고, 모든 임상 척도가 42점에서 59점 사이의 점수를 보이고 있는 정상 프로화일이었다. c. 세번째 집단은 (11.1%) L, F, K척도가 56점에서 70점의 점수에 속하고, Mf척도를 제외한 모든 임상척도들이 60점에서 80점의 점수를 보이고 있다. 이러한 결과들은 다면적 인성검사가 외상후 스트레스 장애군을 구별하는데 신뢰할만한 판별력을 가진다는 것을 시사해 준다. This study was attempted to identify MMPI responses which significantly discriminate between the PTSD and the normal on the basis of MMPI scores. And it was designed to classify the types of MMPI profiles in the PTSD. Subjects were 55 healthy control and 45 PTSD who were inpatient or outpatient in Presbyterian Medical Center from January, 1991 to March, 1993. The results were as follows : 1) In MMPI subscales, except L scale, PTSD had significantly higher score than the normal group. 2) In discriminant analysis, it was D, Mf, Pt, ans Si that discriminate these two groups. Also, it classified 88.9% of PTSD group and 94.5% of normal group correctly. 3) Three subgroups were extracted from the PTSD by cluster analysis of MMPI. a. The first subgroups(54.3%) showed a profile which T score of L, F scale configured a reverted "V" pattern, and T scores of Hs, D, Hy, Pd, Pt, and Sc scale belonged to the range of 60 to 71 point. b. The second subgroup(36%) showed a normal profile which had L, F, and K scale with normal range of 47 to 56 T score and all clinical scales with 42 to 59 T score. c. The third subgroup(11.1%) showed a profile which had L, F, and K scale belonged to the range of 56 to 70 T score and all clinical scales belonged to the range of 60 to 80 T score except Mf scale. These findings suggest MMPI has a remarkable discriminant power in PTSD group.
