CD44 is the major human cell surface receptor for hyaluronate and mediate cellmatrix and cell-cell interactions involved in the mechanisms of tumor invasion and metastasis. Typical acquired melanocytic nevi appear to follow a life cycle characterized by active growth, maturation, and progressive involution, In contrast, congenital melanocytic nevi have a different course and prognosis with potential for development of melanoma, and metastatic spread is very common in malignant melanoma. We investigated the expression of CD44 in acquired and congenital melanocytic nevi, and malignant melanoma by immunohistochemical technique. Formalin-fixed and paraffin-embeded tissue from 5 compound nevi, 6 intradermal nevi, 5 congenital melanocytic nevi, and 5 malignant melanoma were immunolabeled with monoclonal antibodies directed against CD44. All acquired melanocytic nevi showed negative or weak staining for CD44. However, all congenital melanocytic nevi exhibited positive staining for CD44 with minimal irregularities according to location. In malignant melanoma, there was variable intensity of staining for CD44 in different areas of the tumor. These findings suggest that the different expression of CD44 in melanocytic nevi may contribute to different biological behavior between acquired and congenital meanocytic nevi. and CD44 seems to be related to metastasis and tumorigenesis of the malignant melanoma.

The largest Water-Treatment Plant in Daegu draws its raw water from the nackdong River which is increasingly polluted by the growth of urban population and industries around the Daegu City. In conventional water treatment process, the efficiency of the production of treated water is affected by algae concentration in the raw water, especiaally in April, May and September in the dry season. A pilot plant study on the efficiency of the removal of the suspended solids by dissolved air flotation was conducted and the results are summarized as follows : 1. It was confirmed that the production of treated water by the conventional water treatment process decreased especially in dry months when the efficiency of algal removal is low and frequency of back washing is higher than normal. 2. Influent suspended solids and influent turbidity of the raw water of the Nackdong River are related in the formula : Si = 1.6 Ti. From this equation, we derived A/S = (R/A) 1.2 Sa (f.p-1) / 1.6 Ti as control function of dissolved air flotation, we also determinded optimum dosage of alum for optimum conditions of coagulation at the various turbidities of raw water. 3. Polyelectrolyte added increased the effect of flotation in the coagulation process with stabilzation for floc. Treatment effect is also decrased with partial drops of floated particles when sludge of flotation tank is not removdd for a long time. 4. The efficiency of the suspended solids removal in the raw water appears to be fast similar between the air flotation process and the drinking water in the case of the air flotation process. because the detention time needed only 20 minute.

연구목적 : 본 연구의 목적은 광주광역시의 도시 및 농촌 지역에 거주하는 노인에서 치매의 유병률과 위험인자를 조사하고자 하였다. 부가적으로 이 두 지역간에 치매의 유병률과 위험인자를 비교하고자 하였다. 방 법 : 광주광역시의 전형적인 도시와 농촌지역의 65세 이상의 노인(N=1,598)을 대상으로, 2단계의 역학연구를 수행하였다. 1차 선별 단계에서는 38명의 훈련된 연구보조원이 대상노인을 면담하여, 사회인구학적 특징을 조사하고 한국판 간이정신상태검사(Korean version of Mini-Mental State Examination ; MMSE-K)로 평가하였다. 2차 임상 진단 단계에서는 1차 단계에서 MMSE-K 점수가 24점 이하인 노인(N=431)을 대상으로, 전문연구팀의 임상적 평가를 통해 치매를 진단하고 원인질환별로 알쯔하이머병(Alzheimer's disease ; AD), 혈관성 치매(vascular dementia ; VaD) 및 기타 치매로 분류하였다. 대상노인에서 치매의 유병률을 측정한 후, 광주광역시 전체 노인의 연령보정 유병률을 산출하였다. 전체 대상에서 AD의 위험인자를 조사한 후, 도시와 농촌군으로 나누어 분석을 다시 시행하였다. 결 과 : 1차 및 2차 단계의 참가율은 각각 71.0%(N=1,134) 및 83.2%(N=410) 였다. 연구 참여 노인(N=1,134)에서 전체 치매, AD 및 VaD의 유병률은 최소 각각 9.7%, 5.2%, 1.8%였다. 광주광역시 전체 노인의 연령 보정 유병률은 각각 10.7%, 5.7%, 1.9%인 것으로 산출되었다. AD의 독립 위험인자는 고령, 여성, 무학이었다. 도시와 농촌에 따른 유병률의 차이는 파악되지 않았다. 그러나 AD의 위험인자는 지역에 따라 차이가 있었다. 도시 노인에게는 무학만이, 농촌 노인에게는 고령과 여성인 경우가 독립 위험인자였다. 결 론 : 광주광역시 노인에서 치매의 유병률은 높았고, 이는 국내 다른 지역에서 수행된 선행연구 결과와 유사하였다. 알쯔하이머형 치매의 위험인자는 도시와 농촌에 따라 다른 결과를 보였다. 본 연구 결과는 한국에서의 치매의 실태를 반영하며, 치매의 적절한 관리와 예방을 위해서는 지역성 특성이 고려되어야 함을 시사한다. Objectives : The purpose of this study was to investigate the prevalence rate and risk factors of dementia in an urban and a rural sample of older persons in the metropolitan Kwangju area, Republic of Korea. In addition, the prevalence rate and risk factors of dementia between the two samples were compared. Methods : A two-phase epidemiological study of residents aged 65 or over(N=1,598) was conducted in a highly developed, urban and a non-contiguous, poorly developed, rural area of metropolitan Kwangju. In the first(screening) phase, 38 trained research assistants collectively peformed in-home interviews for all participants. Detailed sociodemographic characteristics were gathered and the Korean version of Mini-Mental State Examination (MMSE-K) was administered. In the second (diagnosing) phase, diagnosis of dementia was established for those scoring 24 or less on the MMSE-K in the screening phase(N=431), and etiological types of dementia were classified to Alzheimer's disease(AD), vascular dementia(VaD) or miscellanous type by two teams of experts. Prevalence rate of dementia was determined in the participants, and age-standardized prevalence rate adjusted by age distribution in metropolitan Kwangju was estimated. For AD, the risk factors were investigated in all participants, and analyses were repeated for the urban and rural samples separately. Results : The participating rates in the first and second phases were 71.0%(N=1,134) and 83.2%(N=410), respectively. In the participants, the prevalence rates of dementia(all types), AD and VaD were 9.7%, 5.2% and 1.8%, respectively. The age-standardized prevalence rates were 10.7%, 5.7% and 1.9%, respectively. Aging, female gender and no education(complete lack of formal education) were identified as independent risk factors for AD. No difference between the urban and rural samples was observed in the prevalence rates of dementia(all types), AD and YaD. However, risk factors for AD differed between these areas. In the urban sample, no education was the only significant factor ; whereas, aging and female gender were identified as risk factors in the rural sample. Conclusion : A high prevalence rate of dementia was observed among old persons in metropolitan Kwangju, consistent with previous studies conducted in other Korean areas. The risk factor profi1es for AD differed between urban and rural settings. The results of this study reflect the current status of dementia in Korea and suggests that appropriate management and prevention strategies for dementia should be tailored toward the geographic settings.

Objectives : This study aimed to develop the Korean version of World Health Organization Disability Assessment Schedule II (WHODAS II-K) with community dwelling elderly population. Methods : The WHODAS II-K was administered to 1204 community residents aged 65 or over in two areas of Kwangju, South Korea, in 2001. For assessing 'health condition', data on physical illness, depression (Korean version of Geriatric Mental State Schedule B3), and cognitive dysfunction (Korean version of Mini-Mental State Examination) were collected. For evaluating 'contextual factors', informations on demographic charactehstics (age, gender, living area, marital state, and religiou), socio-economic status (education, type of accommodation, number of room, previous occupation, and current employment), and social network were obtained. Results : WHODAS II-K showed high levels of internal consistency, split-half reliability, and inter-rater and test-retest reliabilities. In the correlation analyses, scores on the WHODAS II-K were significantly correlated with the unfavorable conditions in the all variables on health condition and contextual factors. Partial correlations of scores on the WHODAS II-K with health condition were significant even after controlling for contextual factors. Conclusion : The WHODAS II-K is a reliable and valid instrument for assessing disability in elderly population since it reflects physical illness, depression, and cognitive impairment, which are common in elderly.
