Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

연구목적 : 외환위기 이후에 급증한 노숙자 문제는 경제적인 상황의 호전에도 불구하고 만성화하는 경향을 보이고 있다. 쉼터의 노숙자를 대상으로 정신질환의 유병율과 삶의 질에 대한 조사를 시행하였다. 방 법 : 2000년 3월에 서울의 대표적인 쉼터에 거주하는 노숙자220명을 대상으로 인구학적 자료에 대한 설문조사를 한 뒤 Structured Clinical for DSM-Ⅳ(SCID-I)을 이용하여 AxisⅠ의 주요 정신질환을 진단하였다. 또 SmithKline Beecham Quality of Life Scale(SBQOL)를 사용하여 삶의 질정도를 평가하였다. 결 과 : DSM-Ⅳ AxisⅠ의 정신질환 중 기분장애, 정신병적 장애, 물질 사용 장애에 대한 진단 평가 결과 상기정신질환의 전체 평생 유병율은 73.6%, 현재 유병율은 59.1%이었다. 알코올 의존과 남용의 평생 유병율은 59.5%로 가장 높았고, 기분장애와 장애가 각각 39.5%, 3.6%이었다. 삶의 질은 노숙의 기간이나 실직 기간과 유의한 관계가 없었고, 자신이 지각한 건강상태, 자살과거력, 우울장애 유무와 통계적으로 유의하게 상관관계가 있었다(p<0.01). 결 론 : 노숙자에서 정신질환 중 알코올 장애의 유병율이 가장 높았으며, 우울장애가 있는 경우에 삶의 질이 저하되는 것으로 나타났다. Objectives : Homeless people surged after financial crisis tend to be chronic despite late economic recovery. So we tried to estimate prevalence of mental illness and quality of life of the homeless population living in shelter. Method : The study subjects were 220 homeless peoples who stayed at a shelter in Seoul around March 2000. Questionnaires on sociodemographic data were administered to the subjects, and then diagnoses of major DSM-Ⅳ Axis I mental disorders were made using Structured Clinical Interview for DSM-Ⅳ Axis I Disorders(SCID). And quality of life(QOL) was evaluated by SmithKline Beecham Quality of Life(SBQOL). Results : The lifetime prevalence of major DSM-Ⅳ mental disorders(mood disorders, psychotic disorder, and substance use disorder) of 220 homeless people was 73.6%, and current prevalence was 59.1%. The lifetime prevalence of alcohol dependence and abuse was highest, 59.5% and those of mood disorder and psychotic disorder were 39.5%, 3.6% respectively. Quality of life was not significantly correlated with duration of homelessness and unemploy-ment but marital status, self perceive health status, suicidal attempt history were significant factors. The quality of life in the people with mood disorders were estimated to be lower than those with any other diseases(p<0.01). Conclusion : Alcoholism was the most prevalent mental disorder in homeless people and mood disorder was negatively related to the quality of life scale.

While the enhanced biological phosphorus removal(EBPR), in anaerobic/aerobic condition, was known to remove phosphorus by means of metabolism of poly-Pmicroorganisms, the phosphorus removed could be released in the form of ortho-P in the aerobic fixed biofilm reactor. This study was initiated to investigate the cause of ortho-P release in the aerobi c fixed biofilm reactor. The resutls indicated that the phosporus release was caused by autooxidation. The synthesis and release of phosphrous were related to the ORP and the boundary value for the phase change was about 170mV. In the synthesis phase, the phosphorus removal rate per COD removed was 0.023mgP?/mgCOD?. The phosprous contents of the microorganism were 4.3~6.0% on a dry weight basis.

Eutrophication derived from the excess inflow of organics and nutrients into discharge basins results in the mass production of algae, causing other secondary water pollution. Also, toxic alg-ae have been associated with eutrophication in coastal regions and have been implicated in the occrrernce of "red tide" which may lead to paralytic shellfish poisoning. But existing methods that are weak in the performance of from 10 to 20 percent N, P removals have not coped with the water pollution owing to eutrophication. In this study, to researchtreatment characteristics of media in conventional activated sludge system, existng Conventional Activated Sludge system and Media-introduced Activated Sludge system are made a comparative study using a pilot plant in the field. In the performance of Organic matter removal, Media-introduced methid is better than non Medial method, improving BOD average removal 5%, COD 18%, respectively and in nutrients T-N 27% and T-P 12.3%, average. Experiments have it that Media-including methods with shorten HRTs(5 hours) is more satisfactory than Conventional Activated Sludge system with 7 hours.

우지수,한동철 순천향의학연구소 2004 Journal of Soonchunhyang Medical Science Vol.10 No.1

Background : Actin disassembly is one of the main pathogenic phenomena in diabetic nephropathy. Small GTPases, related with actin cytoskeleton, may have a pathogenic role in high glucose (HG) induced renal injury. Methods : HG-stimulated gene profiling in cultured human glomerular endothelial cells (GEC) was examined by using oligonucleotide microarray technique. Human GEC were isolated from normal part of nephrectomy specimen and cultured under normal glucose (5.6 mM) or HG (30 mM) for 24 h, 48 h and 72 h. Total RNA was purified from the cell and then applied on 10 K-DNA chip (Macrogen) after amplified with T7 RNA polymerase. Results : About 2,400 genes showed 2-fold difference by HG. Approximately, 300 out of 2,400 genes were down-regulated and about 460 genes were up-regulated continuously by HG. Rho GTPase-related molecules and actin cytoskeleton regulatory gene expressions were highly regulated. Rho7, Rho guanine nucleotide exchange factor 1 and 3, and Rho GDP dissociation inhibitor were significantly up-regulated by HG without alteration of Rho GTPase activation protein 5, suggesting increased activity of Rho GTPase. In addition, myosin light chain 2 and 3, and p21-activated kinase, possibly related with actin-myosin interaction, were also significantly up-regulated by HG. Western blot revealed HG induced increase of CDC42 protein expression, not RhoA and Rac1 in total cell lysates of GEC. Conclusion : Enhanced gene profile encoding Rho GTPase and actin cytoskeleton is one of prominent components of the GEC transcriptomic response under HG.
