Objective : There is accumulating data that cardiovascular diseases, including hypertension, cerebro-vascular accident, coronary heart disease, relate to atherosclerotic changes. Increased serum levels of lipids could play a role in these circumstances. the SDPTG(the second derivative of photoplethysmogram waveform) is noninvasive methods for evaluating the pulse wave and is correlated with age and other risk factors for atherosclerosis. Methods : To study the effects of serum lipid levels on the SDPTG in the middle-age adults, data on serum lipid levels and the SDPTG were collected in 80 healthy middle age with varying serum lipid concentrations. Biological vascular age was assessed using the SDPTG. the SDPTG consists of an a, b, c, and d wave in systole and an e wave in diastole; an SDPTG aging index(Al) was calculated as (b-c-d-e)/a. Results : Serum triglyceride, total cholesterol, total lipid, phospholipid, HDL cholesterol levels were respectively and significantly correlated with SDPTG Al. Serum lipid levels and blood pressure are age-dependent and the SDPTG is blood pressure-dependent. Restricting analysis to age and blood pressure yield strong positive correlations between serum triglyceride, total lipid levels and SDPTG Al, but no correlations between serum total cholesterol, phospholipid levels and SDPTG Al. Conclusion : The results of this study suggest that preventive acupuncture programs or herbal medications for reducing serum lipid, especially triglyceride, levels in middle-age should include a evaluation of biological vascular aging with the second derivative of photoplethysmogram waveform.

그 동안 많은 연구자들은 콘크리트의 응력-변형률 관계의 비선형 거동을 적절한 수식으로 나타내기 위해 많은 노력을 해 왔다. 그러나 이 응력-변형률 관계에 대한 대부분의 경험식은 경화된 콘크리트에 촛점을 맞추어 왔으며, 초기재령에서의 콘크리트의 거동을 잘 나타내지 못하였다. 여기서 초기재령에서 경화시까지 걸친 전 콘크리트의 재령에 대한 폭 넓은 이해는 콘크리트구조물의 내구성과 잔존수명을 평가하는데 있어서 매우 중요하다. 본 논문에서는 5가지의 강도수준과 12시간에서 28일까지의 재령에 대하여 응력-변형률 관계를 검토하였으며, 20$\pm$3$^{\circ}C$ 에서 수중양생된 ø100$\times$200mm의 원주공시체에 대하여 1축압축강도실험을 수행했다. 실험결과에 대한 회귀분석을 수행하여 강도와 재령에 따른 응력-변형률 관계의 모델식을 제시하였으며, 제시된 모델식의 검증을 위하여 실험결과와 기존의 실험결과와 모델식에 대한 해석적 검토도 수행하였다. 해석결과, 제시된 모델식이 실험결과와 잘 맞으며 응력-변형률 관계에 강도와 재령이 미치는 영향을 잘 나타내고 있음을 알 수 있었다.

Objectives: The purpose of this study was to examine the effect of women's late age of marriage on the interval between marriage and their first birth Methods: Data from Year 2000 Korea National Fertility Survey was collected through direct interview questionings, and the data was analyzed based on randomly selected sampling. In particular, the married women (N=5,648) were analyzed for the factors that determined the first-birth interval by performing Cox's proportional hazard model survival analysis. Results: Unlike previous findings, the woman whose age of marriage was 30 or more was more likely to delay the birth of her first baby than were the other women who married earlier. Further, a woman's age at marriage, a woman's residence before marriage, her husband's religion, her husband's level of education and the difference in age between the woman and her husband significantly influenced the first-birth interval. In contrast, for a married woman, her age, level of education, current residence and religion were not significant predictors of her first birth interval. Conclusions: Our study showed that women who married at the age of 30 years or more tend to postpone their first birth in Korea. When facing the increasing number of women who marry at a late age, the Korean government should implement population and social policies to encourage married women have their first child as early as possible.

The purpose of this study was to identify the eating habits and attitudes by socioeconomic factors(sex, age, educational level and annual family income) of adults in rural areas. The survey was administered by the nationwide 580 adult persons in rural in February 2001. The survey was conducted by a questionnaire that was composed of 20 items of likert-type scale. These data were analyzed by using SPSS(version 10.0) PC package and were expressed by mean and frequency. The results are following : 1) The degree of efforts to eating safe and fresh food were significantly different according to age(p<0.05), educational level(p<0.001) and annual family income(p<0.001). 2) The degree of efforts to nutritional balanced diet were significantly different by age(p<0.05) and annual family income(p<0.00l). 3) The concern about overeating of energyㆍsaltㆍfat were increased as the educational level goes up(p<0.001). 4) Meal regularity was more regular as age goes up(p<0.05). 5) Regarding for eating a variety of food were differed significantly by age(p<0.05) and educational level(p<0.01). 6) There are significantly different in duration of meal time of the subjects by sex(p<0.001), age(p<0.05) and educational level(p<0.0l). 7) Preference for snacks was significantly different by age (p<0.05) and educational level(p<0.0l). 8) There were significant differences in preference for processed foods(p<0.001) and frequency of using a chemical seasoning in cooking(p<0.05) of the subjects by educational level. 9) As the age(p<0.001) goes up and the educational level(p<0.001) and annual family income(p<0.001) goes down, they did not recognize the necessity for improving eating habits. According to these results, there were differences in eating habits between socioeconomic characteristics group in rural area. Therefore, this study can be used as basic data for specific nutritional intervention program in rural areas.

Background: In postmenopausal women, there is rapid bone loss due to estrogen depletion. In women, reproductive factors such as age at menarche, breastfeeding, and parity are considered risk factors of osteoporosis. Many reports suggest that obesity is associated with a reduced risk of osteoporosis. This nationwide, population-based study aims to identify the association between maternal age and osteoporosis risk in postmenopausal women of different obesity classifications. Methods: We assessed data from the Korean National Health and Nutrition Examination Survey 2010-2012. The study included 1,328 postmenopausal women, after excluding women with missing data for reproductive history among 4,546 postmenopausal women in the survey. Multivariate regression was used to identify the association between childbirth age and postmenopausal bone mineral density after adjustments for confounding factors. Results: The prevalence of postmenopausal osteoporosis was 35.24% (n = 468). After dividing the subjects into obese and non-obese groups based on body mass index (BMI) and waist circumference, there were significant differences between non-osteoporosis and osteoporosis groups with regard to age at first childbirth, age at last childbirth, and parity in the BMI-based general obesity group. The prevalence of osteoporosis was highest in women older than 35 years old at last childbirth. The prevalence of osteoporosis was also greater in women with parity ${\geq}4$ compared to those with lower parity levels. Conclusion: Postmenopausal women of older age at last childbirth and higher parity were at increased risk of osteoporosis in the BMI-based non-general obesity group.

Middle age for women is one of the most important stages of the whole normal life span and has unique problems concerning the psychological and physical health, specifically degenerative musculoskeletal diseases. Therefore middle age women should prepare in order to lead a healthy and fruitful life as they enter/begin old age. As the population of middle age women increase, the demands of nurses who care for this age group also continue to glow. Nurses must be interested in this middle age group of women in Korea. This study was designed to identify the extent of family support and self-esteem of the middle age women with degenerative musculoskeletal diseases and the relationship between them and nurse's contribution to middle age women's health promotion that maintain and promote qualify of her life. The population of this study was 112 women aged 40-60, attending the out patient clinic one University Hospital and one Hospital, in Pusan. The data was collected from 1st August to the 30th of September, 1998 by using 36 items questionnaire. The instrument used for measuring family support was of Chai's(1983) FSS which was modified by Kang's(1984) Family Support Scale. And that for self-esteem was Rosenberg's(1965) Self-esteem Scale. The reliability of Chai's FSS and Rosenberg's instruments were tested by Cronbach's alpha and showed that they were 0.93 and 0.89 each respectively. Data was analyzed by descriptive statistics, t-test, ANOVA, and Pearson's Correlation Coefficient using the SPSS computer program. The results of the study were summarized as follows : 1. The mean score of the perceived family support was $39.31{\pm}9.42$. 2. The mean score of the perceived self-esteem was $33.16{\pm}6.75$. 3. Statistically significant factors influencing the family support among sociodemographic variables was satisfaction of marriage(F=-3.069, p<0.003). 4. Statistically significant factors influencing the self-esteem among sociodemographic variables were age(F=3.992, p=0.000), education(F=2.260, P=0.026), housing (F=-1.987, P=0.049) and satisfaction of marriage(F=-2.305, P=0.023). 5. There was a significant correlation between family support and self-esteem (r=.621, p<.000). In conclusion, perceived the family support was important for middle age women to increase their self-esteem. Nurses should be aware of the necessity of family support in the supportive nursing of middle age women and should be able to make a plan to educate the family about supporting the wife/mother. The continuing study of the health promotion of middle age women to find out variables influencing middle age women' health must continue.
