To evaluate the degree of bone mineral density according to physical activity, lifestyle in pre- and postmenopausal women. The subjects were 951 premenopausal and 1,167 postmenopausal women who have examined in health promotion center of Yeungnam University Hospital in Daegu city from January, 1999 to Januaty, 2001. The test for bone mineral density. The physical activity and life style were evaluated by questionaire through interview. The results were summarized as follow. 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 regular exercise was revealed to have preventive effect for osteoporosis in pre- and postmenopausal women. Among the types of exercise, the most effective exercise was bowling and moderately effective exercise was swimming on prevention of osteoporosis, however, bare hand physical exercise was not significant effect on bone mineral density. 3) The risk for reducing bone mineral density was decreased in women who have higher educational background and income in pre- and postmenopausal. The bone mineral density was highest in white color worker and lowest in blue color worker. 4) The premenopausal women who favor meat were revealed higher bone mineral density than the women who favor vegetable. The women who have drunk none or small amount of alcohol were revealed increased bone mineral density and smoking was a risk factor for osteoporosis. These results suggested that to prevent osteoporosis, the systemized program for promoting anti-osteoporotic factor have to be developed and apply from the thirties whom have maximal bone mineral density.

A multi-functional indoor smog chamber was designed and evaluated lo investigate photochenical or water vapor reaction mechanisms of air pollutants. Various smog chamber experiments could be conducted using ambient air or purified air in this smog chamber. The smog chamber consisted of a housing, a Teflon bag, blacklights, injection ports, sampling ports, and utility facilities. The characteristics of light source, the wall losses of air pollutants, and the quality of purified air were experimentally investigated. The maximum NO₂ photolysis rate was 1.10min^(-1). In a 2.5-m³ Teflon bag, the wall losses of ambient O₃, NO, and NO₂were 1.2~2.4×10^(-3)min^(-1), 0.7~2.0×10^(-3)min^(-1), and 0.4-2.0×10^(-3)min^(-1), respectively. The wall loss of ambient particles ranging 0.05 to 0.2㎛ was 1.8~5.4×10^(-3)min^(-1), which was slightly higher than those of ambient gaseous species. The purified air supply system provided high quality of air with NO₂, < 1 ppb, and total hydrocarbons <5 ppb.

There are some evidences that oxidative stresses have some roles in initiation and progression of the diabetic complications. Superoxide dismutase (SOD) is an essential enzyme for the dismutation of superoxide(:O2^-) radicals, and the activity is changed in some pathologic conditions such as diabetes. The aim of this study was to evaluate the association of Mn-SOD activity and severity of diabetic retinopathy and to compare between before and aftertreatment with vitamin E. The Mn-SOD activities were measured in 75 patients with NIDDM(41 noretinopathy, 21 nonproliferative retinopathy, 13 proliferative retinopathy) by spectrophotometry. The Mn-SOD activity(U/mg protein) was significantly elevated in diabetes after vitamin E treatment. The severity of diabetic retinopathy appeared not be statistically significant. In diabetic patients, there were no correlation between the Mn/SOD activity and the various clinical and biochemical parameters.

This study was conducted to examine aspects of skin care of male students at colleges and universities of male students at colleges and universities and its related factors in order to provide informations on skin care for men. The subjects of this study was 600 men who were students at colleges and universities in Daegu City and Kyungbuk Province. Data were collected from May 1, 2002 to June 30, 2002. The results of this study can be summarized as follows. 1. According to the respondents' socio-demographic characteristics, 55.9% of them was 20 to 24 years old and 29.6% was more than 25 years old. 84.9% of them was university students, while 15.1% was college students. 25.3% belonged to the lower class, while 22.4% belonged to the upper class. 52.7% did not have a girl friend, while 47.3% has a girl friend. 41.8% lived in big cities and 48.1% lived in small and medium cities. 2. 63.0% of the respondents replied that they were in good health, while 8.8% of them were in bad health. 41.9% of them was concerned about face and body skin care, while 14.1% was not concerned about it. Among most serious skin problems, the proportion of acne was highest (44.5%). 3. Among the persons who advised the respondents when they selected cosmetics, the proportion of selecting cosmetics as their own will was highest (44.7%). 25.3% of them selected it by recommendation of female family members and 18.3% selected it by recommendation of the girl friend. In the case of selecting it as their own will, the older they were, the higher the proportion was. In the case of having the girl friend, the proportion of selecting cosmetics by recommendation of the girl friend was higher than that of selecting it by recommendation of female family members. 4. 90.4% of the respondents replied that they never visited skin care rooms, while only 9.6% of them replied that they ever visited them. In the case of visiting skin care rooms, the proportion of the upper class was higher than that of the lower class. 5. According to the frequency of visiting skin care rooms, the proportion of once a week was highest (51.0%). 29.4% of them visited them once per 6 months and 19.6% visited them once a month. 6. In the case of the reasons they did not visit the skin care rooms, the proportion of 'no interest' was highest (36.6%). 23.2% did not visit them because they thought the fee for skin care was expensive and 19.5% did not visit them because they thought the skin care room were only for women. 7. In the variables of giving advice concerning skin care, the proportion of 'their own' was highest (29.8%). The proportion of female family members was 28.2% and the proportion of the girl friend was 27.7%. In the case of the age related to having the girl friend's advice, the proportion of 'over 25 years old' was 31.9% and the proportion of '20 years old to 24 years old' was 26.4%. The proportion of 'less than 19 years old' was 23.5%. The older they were, the more they had the girl friend's advice. 8. According to the sources of getting information on skin care, the proportion of mass media (TV, Radio etc.) was highest (36.7%). 26.0% of them obtained them through the girl friend and 13.9% obtained them through female family members. Only 8.4% got them through magazines. 9. The factors influencing the experience of visiting skin care rooms were experience of side effect of foundation cosmetics, concern about skin care, expiration date of cosmetics or checking of directions of using cosmetics, donsideration of skin character when using soap, and regular exercise for health. From above results, it can be concluded that skin care and beauty specialists working in beauty academies or the department of cosmotology at colleges or universities must make efforts to change the negative recognition of male skin care through deep and comprehensive research. It is also necessary to develop systematic education course and institutionalize the qualification management system.

Objectives : To evaluate the degree of bone mineral density and prevalence rate of osteoporosis according to age and to search the preventive strategy for osteoporosis, the factors that affect on bone density were studied in Physical Characteristics of pre- and postmenopausal women in korea. Methods : The subjects were 961 premenopausal and 1,167 postmenopausal women who have examined in health promotion center of Yeungnam University Hospital in Daegu city from January, 1999 to January, 2001. The test for bone mineral density, biochemical factors, and body composition were done. Results : 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 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. 3) The correlation between body composition adjusted for body weight and bone mineral density revealed similar pattern between pre- and postmenopausal women. The height, lean body mass, muscle mass, mineral content, and mineral fraction were positively correlated with bone mineral density, however, body fat mass, percent body fat, waist/hip ratio, and BMI were correlated negatively with bone mineral density. 4) There was no direct correlation between cardiovascular risk factor and bone mineral density in this study, however, further study is needed because cardiovascular disease and osteoporosis have common risk factor and the prevention of osteoporosis can help to prevent cardiovascular disease. 5) In multiple regression analysis among bone mineral density as a dependent variable and independent variables (age, body weight, height, Ca/creatinine ratio, and alkaline phosphatase (ALP)), ALP revealed 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.

내경동맥의 후하방동맥류 수술시 Ring Clip의 이용 : Report of Five Cases

배시현,김철진,이정청 대한신경외과학회 1993 Journal of Korean neurosurgical society Vol.22 No.12

The development of more appropriate shapes of aneurysm clips will hopefully enable excellent clipping of most types of difficult aneurysms. The clipping of internal carotid artery(ICA) aneurysms protruding inferiorly is relatively difficult and has the high risk of premature rupture during operation using conventional clips. We report five cases of ICA aneurysms protruding inferiorly in the operative field. All aneurysms were successfully clipped with ring clips without difficulty. Our results suggest that the ring clips rather than conventional clips were appropriate in the ICA aneurysm protruding inferiorly in the operative field.
