To find out the state of illness, patterns of medical care utilization, and factors which determine medical care utilization for aged we surveyed 679 rural old persons who live in the Chungnam province from Jan. 10 1991 to Jan. 19. The major findings of this study were as follows : 1. The morbidity rate of chronic illness during last 3 months was 56.4% for all surveyed old persons ; 58.7% for female and 52.8% for male. 2. As expected, 80 years old or above group showed the highest morbidity rate, 60.2% and the 65-69 years age group was the lowest, 50.5%. 3. Old persons who are householder, whose family income is less than 290,000 won per month, and who receive benifits from the public medical assistance program had relative higher morbidity rate than other groups and the difference was statistically significant (p<0.05). 4. The most frequent chronic illness was musculoskeletal disease, 49.6% ; the disease from which the aged had suffered for the longest period was gastrointestinal, 11.6yrs : the cerebrovascular was the disease which inflicts the lowest level of physical ability. 5. 67.1% of 383 persons who were suffering from chronic illness were in need of medical care but unmet ; among the remaining 32.9% who utilized medical care, 19.2% utilized it in local clinics or hospital OPD and 15% in th health centers or subcenters. 6. Old person who are married, whose sons are householder and whose family income is 500,000 won or above per month showed relative higher utilization rate than other groups and the difference was statistically significant (p<0.05). 7. The most common reason why the aged did not utilize, in spite of, need medical care was economic problem, 35.4%. For the aged whose family income per month is 500,000 won or above, however the most common reason was tolerable symptom, 46.9% while persons who answered economic problem were 6.1% of them, the lowest frequency.

오한진(Oh Han Jin),최희정(Choi Hee Jung),오장균(Oh Jang Kyun) 대한임상노인의학회 2001 대한임상노인의학회지 Vol.2 No.2

Background : Osteoporosis, the most common metabolic bone disease, is defined by low bone density and because risk of fragility fracture is strongly related to bone density. Bone loss after menopause accelerated at early stage of menopause, and then decreased. So, we evaluated associations of the general characteristics and lumbar BMD of aged postmenopaisaJ Korean women, and determine the markers of bone turnover simultaneously. Subjects and Methods : 308 postmenopausal Korean women aged over 60 years were evaluated who visited Samsung Cheil hospital & Women's health care center located in Seoul from Jan 2000 to July 2001, with respect to markers of bone turnover and BMD at lumbar spine. We compared changes of markers and changes of BMD of the subjects who stratified 4 groups according to age. We also measured obstetrical history and physical, anthropometric data including body fat. To compare the differences of BMD and markers of bone turnover according to age group, oneway ANOVA test were made. And to determine the contributable factors for lumbar BMD, multiple regression analysis were also made. Results : 1) BMD decreased continuously with age. 2) But, no significant changes of markers of bone turnover among 4 age groups. 3) There were no significant differences in physical anthropometric data among 4 age groups. 4) in Pearson's correlation test, YSM were noted significant correlation coefficients with lumbar BMD. 5) Years since menopause, weight were revealed as important factors that predicting spinal BMD by multiple stepwise regression analysis. Conclusion : We concluded that the bone metabolism was increased and also according to the increased bone turnover, BMD was decreased simultaneously with age in Korean postmenopausal women aged over 60 years. 연구배경 : 골다공증은 고령의 연령층에서 골절과 연관된 많은 합병증 및 병발증을 유발하여 사회적으로 경제적인 부담을 초래하는 것은 물론이고 개인에게는 삶의 질을 감소시킴으로 심각한 문제를 일으키는 질병이다. 고령에서 나타나는 골소실은 폐경 초기와는 다른 것으로 칼슘대사의 이상에서 오는 부갑상선 호르몬의 증가와 연관이 있다고 알려져 있으나 아직 한국인 고령 여성의 골밀도 변화와 골대사 지표의 변화에 대한 연구 결과가 미미하다. 연구방법 : 2000년 1월부터 2001년 8월까지 성균관대학교 의과대학 삼성제일병원 갱년기 클리닉에 내원한 60세 이상 여성 중, 동일한 골밀도 측정기로 골밀도를 측정한 여성을 대상으로 하였다. 대상자들의 설문을 통해 산과력을 확인하였으며, 체격과 지질대사 및 골대사 및 골밀도를 측정하였다. 또한 TSH, FSH 및 estradiol을 측정하였으며, 연령에 따라 4군으로 구분하여 차이를 비교하였다. 연구결과 : 60세 이상의 여성에서 연령의 증가에 따라 골밀도는 지속적으로 감소한 것으로 나타났다. 또한 골대사 지표인 total alkaline phosphatase, osteocalcin과 deoxypyridinoline을 측정하여 비교한 결과 각 연령 군에 따른 유의한 차이를 확인할 수 없었다. TSH, FSH 및 estradiol의 측정치도 각 군에 따른 유의한 차이는 없었다. 요추 골밀도를 예측할 수 있는 인자에는 폐경 기간, 체중, 및 출산횟수 및 유산횟수가 포함되었다. 결론 : 60세 이상의 여성에서 골대사는 지속적으로 증가되어 있는 것으로 생각되며, 또한 이에 따라 골밀도의 감소도 지속적으로 나타나는 것으로 생각된다. 그러나 대상자의 수를 늘리고 또한 음주와 흡연 및 운동 등의 요소에 대한 종합적이며 대한 전향적인 연구가 필요할 것으로 생각된다.

본 연구에서는 철근콘크리트 기둥의 심부구속 철근 이외에 추가적인 외측 횡 보강재료를 보강한 실험체에 대해 반복주기 가력 실험을 수행하였다. 이 목적을 위해 스테인레스 강과 GFRP를 사용하여 외측 횡보강재료를 제작하였고, 실험의 주요 변수로 외측 횡보강재의 종류, 두께 및 보강간격을 선택하였다. 실험결과, 외측 횡보강된 실험체는 무보강 실험체에 비해 연성능력 및 에너지 소산능력의 향상을 확인하였고, 본 연구를 통하여 제안된 외측 횡보강재를 사용한 횡구속 방법은 철근콘크리트 기둥부재의 내진보강에 유용하게 사용할 수 있을 것으로 판단된다. In this paper, reinforced concrete columns test has been conducted under repeated lateral load reversals. The test columns have been reinforced with outside lateral confinement members in addition to transverse reinforcements. For this purpose, a strainless steel and a GFRP have been employed for the lateral confinement members. Primary parameters are types, thickness and spacing of the lateral confinement members. Experimental results reveal that columns reinforced with lateral confinement members exhibit improved ductility and energy dissipation capacity in comparison with those unreinforced. It is thus concluded that the present approach can be of a useful scheme for the seismic retrofitting of reinforced concrete columns.

Objectives: The prevalence of metabolic syndrome has recently increased, Payments from the Korea Labor Welfare Corporation for compensation for mortality in workers caused by cardiovascular and cerebrovascular diseases have also increased in Korea in recent years. The association of metabolic syndrome and cardiocerebrovascular disease has been investigated by several researchers in recent studies, This study was conducted in an attempt to characterize the relationship between metabolic syndrome and Korean cardiocerebrovascular disease risk assessment, and to provide basic data to group health practices for the prevention of cardiocerebrovascular disease. Methods: Health examinations were previously conducted for 1526 male researchers at a private laboratory. The prevalence by age and the odds ratio of metabolic syndrome scores into the "cardiocerebrovascular risk group" (sum of low, intermediate, and high risk groups) of the Korean cardiocerebrovascular disease risk assessment were assessed, in an effort to elucidate the associations between metabolic syndrome and cardiocere brovascular disease risk assessment. Results: The prevalence of metabolic syndrome and inclusion in the cardiocerebrovascular risk group was 11,7% and 22.1% respectively. The severity of metabolic syndrome and cardiocerebrovascular risk assessment showed that individuals in their 40's and 50's were at higher risk than those in their 30's (p<0,001). The age-adjusted odds ratio of metabolic syndrome to cardiocere brovascular risk group inclusion was 5.6. Conclusions: An active prevention program for cardiocerebrovascular disease needs to begin in the 40's, as the prevalence of metabolic syndrome and the risk group of cardiocerebrovascular risk assessment peak in the 40's age group. The odds ratio between metabolic syndrome and the cardiocerebrovascular risk group was high, which indicates that metabolic syndrome scores should be utilized as guidelines during the consultation and behavioral modification program for the workplace prevention of cardiocerebrovascular diseases in group health practices.

N/A Background : There were many strategies to treat postmenopausal women with osteoporosis. Because of bone mass measurement confirms the existence of osteoporosis and also predicts the risk of fracture, the effectiveness of the treatment should be measured by the amount of increased bone mass. Methods : 311 postmenopausal Korean women were evaluated who visited one of university hospital located in Seoul from Aug. 1997 to July 2000, with respect to markers of bone turnover and BMD at lumbar spine. Subjects were classified into 3 groups, peri-menopause, early-menopause, and late-menopause by menopausal states. To evaluate the cost-effectiveness of treatment, we compared changes of BMD after 1-year of treatment and total drug costs for 1-year among 3 groups. And also to evaluated the cost-effectiveness between groups classified by WHO criteria, we also compared changes of BMD and total drug costs after 1-year. Results : Our results showed those findings: 1. The const-effectiveness was similar among 3 groups classified by the menopausal state. 2. Among three groups classified by bone density, osteopenia group showed significantly favorable cost-effectiveness score than normal or osteoporotic group.

Objectives:Alcohol dependence is known to be a disease affecting family function thereby influencing children. This study was designed to evaluate the influence of parents’ drinking and family function on their children’s psychosocial symptoms. Methods:The subjects were consisted of 187 Korean children. Effects of parents’ drinking problems on children were evaluated by the CAST-K (The Korean Version of the Children of Alcoholics Screening Test) questionnaire, family functions by Family APGAR (adaptability, partnership, growth, affection and resolve) and children’s psychosocial symptoms by PSC (Pediatric Symptomatic Checklist)-17. Results:There was a sig-nificant (p<0.01) positive correlation (r=0.374) between CAST score and PSC-17, and a significant (p<0.01) negative correlation (r=-0.302) between Family APGAR score and PSC-17. CAST-K and Family APGAR score had 21.8% explanatory power for children’s psychosocial symptoms by stepwise multiple regression analysis (p=0.000). Conclusion:The above results suggest that the drinking of parents and family dysfunction can produce child-ren’s psychosocial symptoms. When clinicians face children with psychosocial symptoms, they should evaluate the parent’s drink-ing problems and the family function. Also treating a patient with drinking problems, clinicians should evaluate whether their child-ren have psychosocial symptoms or not.
