This study was conducted to compare the validity of obese index among body mass index(BMI), waist to hip ratio(WHR), and waist circumference(WC) and to determine which is the best in relation to cardiovascular risk factors of middle aged Korean(40-64yr).Data from the 1998 Korean Health and Nutrition Survey were used(N=3380). Anthropometric indices and cardiovascular risk factors were measured. Chi-square test, analysis of variance following duncan's multiple range test, partial correlation analysis, and Receiver Operator characteristic(ROC) curves were used in the analysis. There was a significant increasing trend in WHR, systolic blood pressure(SBP), high density lipoprotein cholesterol(HDL), and fasting blood sugar(FBS) with age categories of male and in BMI, WC, WHR, diastolic blood pressure(DBP), SBP, total cholesterol(TC), low density lipoprotein cholesterol(LDL), triglycerol(TG), and FBS with those of female. Specially female had the characteristics of upper body fat and systolic blood pressure risk(p<0.05). Proportions of subjects with lifestyle factors related to cardiovascular risk in overweight or upper body fat group were higher than that of normal group. Higher proportions of subjects were practiced exercise in upper body fat group of male than in other groups. Among 7 cardiovascular risk factors in partial correlation analysis, BMI had the highest correlation coefficient in 6 risk factors in male, whereas WC in 4 risk factors in female. Mean of each obese index according to cardiovascular risk groups except smoker was higher than that of normal(p<0.05). These trends were shown in upper body fat group and female. In ROC analysis of 12 risk factors and health conditions, the largest area under curve among obese indices for risk factors were BMI in male and WHR in female. The optimal cutoff values of each index(BMI: WHR: WC) for one or more cardiovascular risk factors were 23.13: 0.89: 85.35 in male and 23.57: 0.84: 78.35 in female. The results showed that cardiovascular risk factors were prevalent in middle aged Koreans within normal limits of obese indices like another Asians. For the identification of cardiovascular risk factors of middle aged Koreans, BMI for men and WHR for women are appropriate indices. But it is recommended that BMI, WHR, and WC, all three indices should be considered, when using these indices.

Powder, or a concentrate, of maesil (Prunus mume) were used in the making of kochujang, and were added to kochujang at 0.5 or 1.0% (w/w). Kochujang fermented with maesil powder lower moisture content than did samples fermented with maesil concentrate. Moisture content slowly increased during fermentation, and was $3{\sim}4%$ higher than the initial value after 8 weeks of fermentation. Kochujang fermented with maesil powder or maesil concentrate showed lower pH values and higher total acidities than did the control. The total microbial count was $3.6{\times}10^7\;5.4{\times}10^7\;cfu/g$, and yeast and mold levels were $2.0{\times}10^7{\sim}3.6{\times}10^7\;cfu/g$, as kochujang fermentation commenced. Microbial load reached a maximum by 4 weeks of fermentation, and decreased thereafter. L (lightness), a (redness) and b (yellowness) values of kochujang gradually decreased during fermentation. Compared to methanol extracts of kochujang, water extracts and ethanol extracts showed higher free radical scavenging abilities at the initial stage of fermentation. Control, and samples with 0.5% (w/w) maesil powder or maesil concentrate, attained higher scores in sensory evaluation tests than did samples with higher maesil levels, and were not significantly different at P>0.05 as determined by Duncan's multiple range test.

This study aimed to present cosmetic countermeasures for preventing fast aging process in the middle age and accepting healthy aging both physically and mentally by investigating the perception of aging according to the health condition, lifestyle and psychological condition targeting mid-aged women in 40s to 50s residing in Seoul and Gyeonggi-do Province. The data collection period was from July 25 to Sept 1, 2015. The data was analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. It was shown that as the age was higher, the menopause ratio was higher, drinking, exercise volume and hours of sleep were reduced and the stress and psychological pressure were higher. According to the menopausal status, the status of facial aging showed a significant difference (${\chi}^2=39.692^{***}$, p<.001), and it also showed a difference according to the status of leisure (hobby) activity (${\chi}^2=22.470^{***}$, p<.01). Also, as higher the age and closer to the menopause in items including the progress of aging, anxiety about aging and improvement efforts, more negative perception was shown, indicating that it is necessary to prepare cosmetic countermeasures for mid-aged women in like a second puberty 40s to 50s although aging and menopause around 50s are very natural. If a beauty alternative is provided, it will help them to have a successful retirement.

This study has been done for the purpose of investigating the degrees of death orientation and terminal care performance. The factors related to these two variables, and the relationship between death orientation and terminal care performance. The subjects of study were 128 nurses who implemented nursing care for terminally ill patients at C University Hospital in Kwang Ju city. The data were collected from March 13 to 19, 1996, by means of Death Orientation by Thorson Powell(1988) and Terminal Care Performance Scale by researcher. The data were analysed by t-test, ANOVA, Duncan test and Pearson's correlation coefficient. The Results of this study were summarized as follows : 1. The mean score of death orientation was 61.4. The degree of death orientation showed no significant difference depending on the general characteristics of nurses. 2. The mean score of terminal care performance was 45.5. In comparison of the degree of terminal care performance among three domains, the mean score of each item tended to show higher degrees in order of 'Psychological domain(2.4)', 'Physical domain(2.2)', 'Spiritual domain(1.9)'. 3. The degree of terminal care performance showed significant differences in age(F=11.48 p=.0001), marital status(t=10.49 p=.0015), religion(t=5.01 p=.0270), period of clinical experience(F=10.30 p=.0001) and ward unit(F=3.73 p=.0036). The degree of terminal care performance in physical domain showed significant differences in age(F=7.26 p=.0010), marital status(t=9.72 p=.0023), period of clinical experience(F=7.03 p=.0013), ward unit(F=6.23 p=.0001). The degree of terminal care performance in psychological domain showed significant differences in age(F=8.73 p=.0003), marital status(t=4.22 p=.0419), religion(t=5.59 p=.0196), period of clinical experience(F=6.36 p=.0023), ward unit(F=3.33 p=.0075). The degree of terminal care performance in spiritual domain showed significant differences in age(F=8.30 p=.0004), marital status(t=10.45 p=.0016), religion(F=5.41 p=.0216), period of clinical experience(F=8.80 p=.0003). 4.

Cytotoxic substances in dental calculus and root cementum of periodontally diseased teeth inhibit new attachment and regeneration. The purpose of scaling and root planing is to remove pathologic structures harboring these cytotoxic substances in order to create a biologically acceptable root surface. However, these procedures inevitably leave a non-biocompatible smear layer. Conventionally, the smear layer has been removed with low pH etching agents such as citric acid, phosphoric acid and tetracycline hydrochloride(TC). Lately, a supersaturated neutral pH etching solution of ethylene diamine tetraacetic acid(EDTA) has been found to be as effective as low pH etchants with respect to smear removal and to be superior in exposing root surfaceassociated collagen. The aim of the present study was to determine the effect of root surface treatment using EDTA on the initial attachment of human gingival fibroblasts. 27 human teeth, extracted due to severe periodontitis, were cut into dentin slices after root planing. The specimens were divided into TC group(treated with $50㎎/m{\ell}$ tetracycline-HCl, pH 1.52), EDTA group(treated with 17% EDTA, pH 7.4), and non-treated control group. After sterilization, 5th subcultured human gingival fibroblasts were seeded in each culture well containing a prepared root slice and incubated for 15 min., 60 min., and 4 hours in 5% $CO_2$ incubator at $37^{\circ}C$. At each incubation time, the number of attached fibroblasts were counted on the microphotographs taken at a magnification of x100. The difference of the number of attached cells between groups was statistically analyzed by the ANOVA followed by Duncan test in SPSS/PC＋programs. The results were as follows : 1. After incubation for 15 min, the attached cells were significantly more in EDTA group and TC group than non-treated control group(p<0.05), but there was no significance in the difference between EDTA group and TC group(p>0.1). 2. After incubation for 60 min and 4 hours, there was no significant difference in the number of attached cells between all groups(p>0.1). 3. In both EDTA group and TC group, there was no significant difference in the number of attached cells between different incubation(p>0.1). But in control group, the number of attached cells was significantly increased after incubation for 60 min, compared with incubation for 15 min(p<0.05). The above results suggest that root surface treatment using EDTA could enhance the initial attachment of gingival fibroblasts to root surface as effective as tetracycline-HCl.

This study is designed to support the development and the teaching of revised curriculum of 2007 "Technology & Home Economics" by investigating the actual condition and the necessity of education for elderly housing education. Questionnaire survey was conducted with 488 high school students in Gyeongnam in 2008. The data analyzed by descriptive statistics, t-test, One-way ANOVA, Duncan's multiple range test by using SPSS 14 program. The results showed that most of the students were dissatisfied with their middle school education of elderly housing due to the lack of interesting and practical contents. Thus, various teaching-learning methods where student can experience and experiment is needed. Also, the students demanded more of factors of elderly housing, spacing plan, elderly welfare service and less of three-generation housing and senior housing in their elderly housing education. The needs of education contents differed among students depending on variables such as sex, graduated middle school, household income, dwelling space and length of residential years. Therefore, revised 2007 curriculum of "Technology & Home Economics" should include required contents in related chapters. Because there are significant differences among textbooks about elderly housing, further attention needs to be paid to the new textbooks in order to include education contents evenly. At the same time, teachers should organize their teaching contents considering the divergence of variables. The effect of elderly housing education will be maximized if the revised curriculum consists of more experimental activities such as elderly simulation in the local community.

Objectives: The purpose of this study was to assess input for health promoting schools (HPS), and to evaluate HPS based on WHO's guidelines through school characteristics, and to identify the schools' need among six areas of HPS. Methods: A stratified and random cluster sampling design was used to obtain a cross-sectional sample. A total of 59 elementary, middle and high schools in Seoul and Gyeonggi areas were included, and 333 teachers (males 40.6%, females 59.4%) participated in this survey. A self-reported questionnaire consisted of ten items for input for HPS, 50 items for the evaluation of HPS and three items for the schools' needs among six areas of HPS. Data was analyzed through a t-test, ANOVA, and a Duncan test. Results: The mean score of input for HPS was 48.5 ($\pm$15.3). Elementary schools had higher mean scores of input than middle schools. The mean score of schools with a management committee was higher than those schools without it. The schools which had meetings on health issues had higher mean scores. The mean score for HPS was 76.8 ($\pm$9.4): the area of "School Physical Environment" had the highest score (80.0$\pm$10.9), and the area of "Community Relationships" had the lowest score (67.1$\pm$13.9). Elementary schools had higher mean scores of HPS than middle and high schools. The schools which had less than nine classes and more than 31 classes had higher mean scores. The mean scores of schools with less than 340 students and more than 1201 students had higher. The schools which had meetings on health issues had higher mean scores. The same results were found on six areas of HPS. The teachers responded that the areas of "School Health Policy", "The School Physical Environment", and "Health Service" should be supported among the six areas of HPS. Conclusion: Based on these results, more concerns and support for school health are necessary. Middle schools should give more regard on the development of HPS. For comprehensive school health promotion, all six areas of HPS should be equally supported.

Purpose: The purpose of this study was to examine the relationship of the general characteristics of health-related majors to their life expectancy scale, depression scale, health perception scale, subjective wellbeing scale, somatic symptom scale and college life stress scale. And it's also meant to analyze influential factors for their stress about college life. Methods: The subjects in this study were the students who were in the department of dental laboratory technology and the department of dental hygiene at a college located in the region of Iksan, North Jeolla Province. Data were gathered in November and December, 2012. The life expectancy scale, depression scale, health perception scale, subjective wellbeing scale, physical symptom scale, somatic symptom scale and college life stress scale of the general characteristics were analyzed by t-test and one way analyses of variance (ANOVA) and the Duncan's multiple range test at the 95% confidence level to assess the statistical significance. And stepwise multiple regression analysis was conducted to determine what factors would affect the stress of the students about college life. The data were analyzed with the windows ver. 12.0(SPSS GmbH, Germany) statistical software program. Results: Among the general characteristics, there were significant differences according to gender and age in all the variables that were life expectancy scale, depression scale, health perception scale, subjective wellbeing scale, physical symptom scale and college life stress scale. 61.3% of the students responded they slept for six hours or less, and the respondents who slept for six hours or less scored significantly statistically lower in health perception scale, subjective wellbeing scale and physical symptom scale. As for college life stress, the respondents who got depressed more often, whose subjective peace or happiness was lower, whose life expectancy was lower, who had worse physical symptoms, whose living standard was lower and whose academic year was lower were under heavier stress about their college lives. Conclusion: As the worse physical health and worse mental health(life expectancy, depression, health perception, subjective wellbeing and physical symptoms, etc.) of the college students led to heavier stress about college life, how to promote their physical health and mental health should discreetly be considered, and every necessary measure should be taken to improve their physical and mental health.
