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.

광산에서 배출되는 광재폐기물은 산과 계곡에 투기 또는 매립되어 강우등에 의하여 주변 소하천을 오염시키고 있다. 따라서 본 연구는 광재의 물리적특성과 이화학적 특성을 조사하고 회분식과 칼럼식실험을 수행하여 오염물질의 침출특성을 고찰하고자 하였다. 실험결과, 다음과 같은 결론을 얻을 수 있었다. 1) 광재는 점토질 및 실트질의 크기를 지니고 있으나 점착력과 소성적 성질이 없는 사질토의 특성을 지니고 있다. 2) 광재의 투수계수는 대부분 10(???)³-10(???)cm/sec의 범위이며, 일반 사질토의 투수계수보다 낮음을 알 수 있었다. 3) 회분식과 칼럼식 용출시험의 결과, 대상 광산의 광재폐기물 일부에서 기준치 이상의 중금속농도가 침출되었으며, 이에대한 방지대책의 심각성을 알 수 있었다. 4) 광재 폐기물의 칼럼식 용출시험 결과 kg폐기물 당 인공강우 투여량 비가 증가할수록 침출수의 중금속 및 유해물질 농도는 크게 감소되어 어느정도 진행된 이후부터는 대부분 일정한 농도가 유지되나, 산성강우시 침출정도 및 침출시간은 지속되는 것을 알 수 있었다. 5) 광재는 많은 중금속과 유해물질을 함유하고 있으나 양적인면에서 자원화의 가치가 높을 것으로 판단된다. 따라서 광재내의 자원회수, 건설 재료등의 재활용및 자원화 연구가 필요하다. Tailing wastes producedat metal mines have been disposed of by dumping or landfiling in depression. Mine drainage developed at pile of the tailing wastes has high concentrations of various kinds of heavy metals and harzardous materials, and these contaminants are leached out from the tailing wastes by water infiltration or when they collapse. In this study, both batch test and column test were performed in order to investigate the physical and leaching characteristics of tailing wastes. The batch test results were compared with those by EPT and DLT, and column test was carried out at acidic and neutral pH ranges. The results showed that high concentrations of heavy metals and sulfate were contained in the leachate of the some tailing wastes. In column test, levels of heavy metals in the leachate produced during the initial rainfall period were found higher.

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.

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.

한일우,곽동일 啓明大學校 醫科大學 1997 계명의대학술지 Vol.16 No.3

AD는 노년기의 대표적인 퇴행성 중추신경계 질환으로서 다양한 인지기능 장애, 정신적 증상, 그리고 기능 장애를 초래하는 만성적 질병이다. 인지기능 장애로서는 기억 장애, 실어증, 실인증, 실행증, 시공간 구성 능력의 장애 등이 있다. 기분 장애, 망상, 환각, 수면 장애, 공격적 행동 등은 정신 증상에 속한다. 아직까지 원인적 치료는 불가능하므로 사망에 이르기까지 계속 진행한다. 임상증상이 발현한 이후의 평균 수명은 7-10년으로, 대부분은 폐렴으로 사망한다. AD is one of the most prevalent degenerative CNS diseases among the elderly. It is characterized by the insidious onset and relentless gradual progression of symptoms and is manifested with a variety of impairments in neurocognitive functions, mental symptoms and functions. There is no causative treatment for the condition. Average survival is estimated 7 to 10 years, ranging from 2 to 25 years, from the onset of clinical symptoms. Pneumonia is the most frequent cause of death in the late stage.

한운우,박동학 大田大學校 環境問題硏究所 1997 환경문제연구소 논문집 Vol.2 No.-

대전광역시에서 음용수로 이용되는 지하수(생수)에 대한 시민들의 인식도를 파악하기 위하여 1996년 4월 무작위로 200명에 대해 현장에서 설문지조사를 실시하였다. 조사결과 수도물은 나쁘며(37%) 수돗물에 비해 생수가 수질이 좋다는 생갹(42%)이 생수를 찾는 주된 이유이며 생수에 대한 신뢰도는 높은(91.1%) 반면 수질검사결과에 대한 인지도는 아주 낮아 무의식적으로 생수를 신뢰하는 것으로 나타났다. 약수터나 공동우물을 이용하는 빈도는 대부분 일주일에 한 번 이상(89%)이며 음용시에는 대부분 끓이지 않은채 그냥 마시는 것(88%)으로 조사되었고 날이 갈수록 생수의 수요가 늘고 있는 것으로 나타났다. The purpose of this study was to investigate the citizen's cognition degree for the ground water(or natural water) in Taejon. This survey was carried out through questionaries in April, 1996. The subjects were 200 citizens sampled at random in the well. The results were as follow. The dominant reasons why they drinked natural water were that tap water was not good(37%) and mineral water was generally good(42%). The reliance on the natural water was very high(91.1%) but cognition degree for water quality was very low. It was found that people unconsciously have reliance on natural water. It was investigated that people took the natural water more than once per a week(89%) and drinked it not boiled (88%). And the use of ground water gradually increased.

The purpose of this study was to investigate the characteristics of ground water (natural water) quality in East Taejon. This study was carried out by experiment on the well of the easterm area of Taejon and the observed groundwater quality data. I was found that F, Mn, Zn, COD, NO3-N, ordorness, turbidity, hardness, bacteria and E-coli exceeded the water standard. In general, the southern area of Dong-Gu and the northern area of Taeduk-Gu relatively had a good groundwater quality and the pollutant concentration in the area densely populated was higher than the other areas. Bacteria and E-coli were detected mainly at the well of low depth is summer, which will have to be examined preponderantly. It was found that the pollutant concentration of ground water increased every year. Therefore, there will be necessity for the management of groundwater quality pollution in future.
