Objectives : This study was conducted to evaluate the prevalence rate of osteoporosis according to age and the effect of physical characteristics and obstetrical history on bone mineral density in pre- and postmenopausal women in Korea. Methods : The subjects were 961 premenopausal and 1.167 postmenopausal women who had been examined in health promotion center of Yeungnam University Hospital in Daegu city from January, 1999 to January, 2001. The test for bone mineral density, and body composition were conducted. Results : The results of this study were as follows; 1. The prevalence rates of reduced bone mineral density and osteoporosis in premenopausal women were 23.8% and 1.6%, respectively. However, these values were increased to 46.1% and 28.1% in postmenopausal women. 2. The age was most important predictive factor for bone mineral density in pre- and postmenopausal women. The bone mineral density was peaked at the thirties and declined sharply around fifty years old and declined slightly after the seventies, which revealed a typical cubic equation. The loss of bone mineral density was started at forty years old. 3. The body weight and height were important predictive factors for bone mineral density. The effects of age, body weight, and height on bone mineral density were 39%. The body weight was correlated statistically significantly with bone mineral density in pre- and postmenopausal women. The higher body mass index (BMI), the greater value of bone mineral density was revealed in pre- and postmenopausal women. 4. In multiple regression analysis, age, body weight, height showed statistically significant inverse correlation with bone mineral density. Conclusions : These results suggested that to prevent osteoporosis, the systemized program including physical condition for promoting anti-osteoporotic factor have to be developed and apply from the thirties whom have maximal bone mineral density.

The study was designed to gain necessary basic data in order to grasp the health knowledge, attitude, and practice level of students and teachers of elementary, middle and high schools. This study was conducted through interviews of 3,400 students and 1,022 teachers attending 14 different schools large, middle and small cities and rural towns during a period of nine months (from Oct. 2 1995 to Jun. 30 1996). By the results of this study, the recommendations can be summarized as follows: 1. A school health development committee should be established of 10 members: school health related teachers (physical trainers, nurses, and teachers in charge of health, parents, persons related to health administration, local medical doctors, and student reprensentatives in order to support and immplement school health development plans. 2. Like advanced countries, a health class of 2∼4 hours should beplaced in middle and high schools. A nurse majoring in health from a university should be the teacher. 3. A curriculum of health should contain the following; education on health, sex alcohol, tabacco, the misuse of the drugs, the structure and function of human body, the growth of the body, mental health safety and emergency care, the prevention of disease, proper eating habits and nutrition, daily health life, family health education, society health, community health, environmental pollution and individual respnsibility.4. Create a school health promotion center, with a nurse's office, and a sports center which has health machines (bars, aerobics, training, twist machine, belt massage, running machine, bench press, chest waist back hip extension machine) as well as a physical strength measuring machine (muscular strength, alertness, flexibility, endurance, long functions and so on), so that the teaching staff and students can use them and train their bodies. 5. Through a refresher education program, urge teachers to understand school health promotion services. 6. Regulate a standard and establish a system of monitoring the physical enviroment of the school (the height of desks and chairs, illumination facilities, ventilation facilities safe drinking water).7. Create a check list of health to evaluate improvement.

남철현,Nam, Chul-Hyun 대한예방의학회 1992 예방의학회지 Vol.25 No.2

신체나 정신적으로 건강한 남자 대학생 15명을 대상으로 시판 소주(25%)를 식사 후 $3{\sim}4$시간 지나서 체중 kg당 ethyl alcohol 1ml(60kg 체중의 경우 소주 4잔, (240ml 또는 맥주 $2\frac{1}{5}$병 정도)되도록 마시게 한 후 시간별(5, 30, 60, 90분)로 Alcohol Sensor 100을 사용하여 호기로 혈중알를농도를 측정하고 선택반응시간검사(교통 신호등 반응시간검사), 눈과 손의 협동능력기능검사 및 연속가산에 의한 계산능력기능검사를 술을 마신 후 시간별로(5, 30, 60, 90분) 실시하여 다음과 같은 결과를 얻었다. 1. 술을 마셨을 때의 호기로 측정한 혈중알콜농도는 술(소주)을 마신 후 5, 30, 60, 90분에 중량백분율로서 각각 0.16%($160{\pm}57mg/100ml$), 0.10%($100{\pm}42mg/100m1$), 0.08%($80{\pm}36mg/100m1$), 0.03%($30{\pm}24mg/100m1$)로서 음주직후인 5분후에 0.16%로서 가장 높은 농도를 보였고 그 후는 점차 떨어져 30분, 60분에는 0.10%와 0.08%로 나타났다. 그리고 술을 마신 직후 호기로 혈중알콜농도를 측정할 경우 실제 혈중알콜농도보다 높게 나타날 가능성이 있다. 2. 선택반응시간검사(교통신호반응시간 검사 : 즉 빨간 정지신호를 보고 브레이크를 밟는 시간)에서는 혈액중 알콜농도가 증가함에 따라 반응시간이 길어졌으며, 술을 마신후 혈중농도가 0.16%, 0.10%, 0.08%를 보인 5분, 30분, 60분에서는 음주전보다 유의하게 늦어졌으며, p<0.01, 음주후 5분과 30분 후에는 0.46초 및 0.44초로서 음주전의 0.40초보다 0.06초와 0.04초 늦어졌다. 3. 눈과 눈의 협동능력검사에서는 혈중알콜농도가 높아감에 따라 작업수행의 정확도가 떨어졌는데 혈중농도가 0.08% 이상을 보인 음주후 5분과 30분, 60분후(p<0.05)에는 유의하게 협동능력이 떨어졌다. 4. 연속가산검사에서는 계산능력이 혈중농도가 0.08% 이상에서 계산의 정확성과 속도가 유의하게 떨어졌다. This study was carried out not only to determine blood alcohol levels by time but also to examine the changes of working ability and reaction speed after ingestion of alcohol. Fifteen healthy students aged from 21 to 27 volunteered as subjects for this study, Liguor (Sojoo) in concentration of 25% ethyl alcohol was administrated with the amount of 1ml of ethyl alcohol per kg of body weight to the subjects. The concentration of alcohol in the blood were determined by the 'Alcohol Sensor 100' at 5, 30, 60 and 90 minutes after the administration of alcohol. Also, the choice reactiontest, the eye-hand coordination test and kraepelin test were examined at the same time after checking of alcohol concentration in the blood. The results of this study can be summarized as follows. 1. Mean blood alcohol level changes resulting from administration of 1ml of ethyl alcohol per kg of body weight were $0.16%(160{\pm}57mg/100ml,\;0.10%(100{\pm}42mg/100ml),\;0.08%(80{\pm}36mg/100ml)\;and\;0.03%(30{\pm}24mg/100ml)$ at the 3, 30, 60 and 90 minutes after the administration respectively The peak in the concentration of blood alcohol was 5 miniutes after the ingestion according to alcohol examination by the respiration. 2. As for choice reaction test, reaction times became prolonged as blood alcohol levels increased. The reaction time showed a significant changes when the blood alcohol concentration reached 0.08% or more after alcohol ingestion. 3. In eye and hand coordination test, the accuracy of the performance became decreased as blood alcohol levels increased. The difference of accuracy of the test was significantly shown when alcohol levels in the blood reached 0.08% or more after alcohol intake. 4. As for kraepelin test, the abilities of calculation also became lowered as blood alcohol levels increased. The abilities of calculation differed signigicantly from control group when alchool levels of 0.08% and more.
