The purpose of this paper it to investigate the differences in prevalence of obesity and body fat distribution on the variances of age. Height, weight, skinfold thickness and girth circumference on about 422 women residing in Cheju, Korea were surveyed. The results of analysis of the survey are as follows : 1) All the antropometric measurements except height were shown to increase with age. Weight is at its highest level between the age of 50-59. The measurement of skinfold thickness and girth circumference between the ages of 20-39 of the female subjects are significantly higher than the above 40's. However, there is no significant difference among the middle aged women. 2) Physical indices tend to increase according to age. Both BMI and RBW of women in their 50's are at their highest values, however, the index values of the women in their 60's decreased slightly (p<0.05). On the contrary, there is no significant difference in the percentage of body fat and total body fat content among the middle aged women surveyed. 3) According to this survey, 15.6% of the 422 subjects are assessed as being obese ; more specifically 4.4% of women in their 20's, 12.6% in 30's, 25.6% in 40's, 22.5% in 50's and 17.3% in 60's. 4) 39.4% among obese women proved to be upper body type women. Because the frequency of upper body type women became higher as the obese women aged, there is possibility that the pattern of fat distribution can change. 5) Weight is the most highly correlated with BMI(r=0.91), whereas weight as correlated with RBW, percentage of BF and WHR are 0.8, 0.66 and 0.44 respectfully. The conclusion of this survey is that it is better to estimate the value of total body fat and percentage of body fat than the value of BMI in the analysis of prevalence of obesity and its related factors of middle aged women.

Background : Most previous studies regarding the role of GSTMl and GSTT1 on lung cancer risk have been focused mainly on male smokers. However, epidemiological characteristics, histologic types and risk factors are different in female and male lung cancers, we investigated the association between these genotypes and lung cancer risk in males and females separately. Materials and Methods : The study population consisted of 253 lung cancer (153 males and 100 females) and 243 controls (140 males and 103 females). GSTM1 and GSTT1 genotypes were determined by a multiplex PCR. Results : In the male population, neither GSTM1 nor GSTT1 null genotype showed significant difference between cases and controls. In the female population, the frequencies of GSTM1 null genotype showed no significant difference between cases and controls. However, the frequencies of GSTT1 null genotype was significantly higher in cases (70.3%) than controls (55.3%, odds ratio (OR)=2.18; 95% confidence interval (CI=l.21-3.93). When the female population was stratified by age and smoking status, the ORs for GSTT1 null genotype were significantly higher in subgroups of ${\leq}60$ years (OR=4.82; 95% CI=l.61-14.4) and never-smokers (OR=4.29; 95% CI=1.94-9.48) but not in subgroups of >60 years or smokers. When stratifying the female never-smokers by age, the ORs for GSTT1 null genotype were significantly higher in both age groups of ${\leq}60$ years (OR=7.64; 95% CI=2.00-29.2) and >60 years (OR=2.89; 95% CI=1.05-7.94). Conclusion : We found that GSTT1 null genotype was associated with an increased risk of lung cancer in Korean female never-smokers. This result suggests that GSTT1 null genotype could be used as a biomarker for genetic susceptibility to lung cancer in Korean female never-smokers.

The purpose of this study is to empirically analyse determinants of elders' life satisfaction by gender and discuss policy implications for the findings. Data was obtained from the Social Statistics Survey conducted by the Korea National Statistical Office in 2013. From this dataset, 9,456 elders aged 60 and above (4,113 male, 5,343 female) were selected for this study. Results of ordered logit analysis found differences for determinants of elders' life satisfaction by gender. Results of this study can be summarized as follows: First, age has a significant positive effect on only male elders' life satisfaction. Second, education level has a significant positive effect on both male and female elders' life satisfaction. Third, having a spouse has a significant positive effect on only male elders' life satisfaction. Fourth, household income has a significant positive effect on both male and female elders' life satisfaction. Fifth, consumption life satisfaction has a significant positive effect on both male and female elders' life satisfaction. Sixth, house ownership has a significant positive effect on both male and female elders' life satisfaction. Seventh, preparation for aging has a significant positive effect on both male and female elders' life satisfaction. Eighth, each of three types of social support has a significant positive effect on both male and female elders' life satisfaction. Ninth, cohabitation with children has a significant negative effect on both male and female elders' life satisfaction. Tenth, volunteerism has a significant positive effect on only male elders' life satisfaction. Eleventh, social group participation has a significant positive effect on both male and female elders' life satisfaction.

The purpose of this study was to examine differences between 20s and 60s in blood oxygen saturation due to 93% oxygen administration of the three levels(1L/min, 3L/min, 5L/min). Ten 20s male($25.0{\pm}1.8$ years), ten 20s female($23.7{\pm}1.9$ years), ten 60s male($68.0{\pm}2.6$ years), and ten 60s female($65.5{\pm}3.1$ years) were selected as the subjects for this study. The oxygen supply equipment(OXUS Co.) provided oxygen by supply rate(i.e., 1L/min, 3L/min, and 5L/min) at a constant rate of 93% oxygen. The experiment consisted of three phases, i.e., Prehyperoxia(5min), Hyperoxia(10min), and Post-hyperoxia(5min). Blood oxygen saturation were measured throughoutthe three phases. By increasing the amount of highly concentrated oxygen administration, blood oxygen saturation was increased. Blood oxygen saturation of 20s was higher than 60s. Blood oxygen saturation was greater during Hyperoxia than during Pre- and Post-hyperoxia. However, rising rate of blood oxygen saturation of 60s by oxygen administration was higher than 20s.

Background: Anatomic changes in the acromion have been considered a main cause of shoulder impingement syndrome (SIS). To evaluate the relationship between SIS and the acromion process, we devised a new morphological parameter called the acromion process cross-sectional area (APA). We hypothesized that the APA could be an important morphologic diagnostic parameter in SIS. Methods: We collected APA data from 95 patients with SIS and 126 control subjects who underwent shoulder magnetic resonance imaging (MRI). Then we measured the maximal cross-sectional area of the bone margin of the acromion process on MRI scans. Results: The mean of APAs were 136.50 ± 21.75 ㎟ in the male control group and 202.91 ± 31.78 ㎟ in the male SIS group; SIS patients had significantly greater APAs (P < 0.001). The average of APAs were 105.38 ± 19.07 ㎟ in the female control group and 147.62 ± 22.90 ㎟ in the female SIS group, and the SIS patients had significantly greater APAs (P < 0.001). The optimal APA cut-off in the male group was 165.14 ㎟ with 90.2% sensitivity, 91.4% specificity, and an area under the curve (AUC) of 0.968. In the female group, the optimal cut-off was 122.50 ㎟ with 85.2% sensitivity, 84.9% specificity, and an AUC of 0.928. Conclusions: The newly devised APA is a sensitive parameter for assessing SIS; greater APA is associated with a higher possibility of SIS. We think that this result will be helpful for the diagnosis of SIS.

Purpose: The purpose of this study was to investigate the health promotion behavior according to body mass index (BMI) and self-perception of obesity in female nursing students. Methods: The subjects of this study were 143 female nursing students. The data were collected using a questionnaire about health, life style and general characteristics. BMI, waist and hip circumference, flexibility, and gripping force were measured. Data were analyzed with SPSS/WIN 20.0 program. Results: Subjects were divided into three groups including true overweight (16.1%), false overweight (29.2%), and true normal weight group (43.5%) based on their BMI and self-perception about obesity. There were significant differences among the three groups in alcohol consumption, self-confidence on the accomplishment of desired weight in a year, gap between actual and desired weight, waist circumference, waist-hip ratio, and interpersonal relationship. The true normal weight group shows significantly higher interpersonal relationships than the true overweight group. Conclusion: It was determined that special strategies for increasing appropriate self-perception about obesity and health behaviors for female nursing students should be developed.

This study aimed to measure and evaluate the intakes of four antioxidant trace elements, namely, Zn, Cu, Mn, and Se in 19-29y-old female university students in Korea. Diet data were collected by 3-day dietary records in 644 subjects. The mean age, height, weight and body mass index of the subjects were 20.08 years, 161.77 cm, 54.26 kg and $20.82kg/m^2$, respectively. The mean, median and 25th-75th percentile intakes of Zn, Cu, Mn, and Se in the subjects were 12.83 mg (12.40 mg, 9.59 to 15.34), 1.30 mg (1.27 mg, 1.00 to 1.57), 3.19 mg (3.12 mg, 2.45 to 3.86), and $50.90{\mu}g$ ($50.17{\mu}g$, 37.59 to 64.35), respectively. The proportion of subjects whose Mn intake was adequate or less was 62.89%, and the proportions of subjects whose Zn, Cu and Se intakes were at the estimated average requirements or less were 10.09, 4.97, and 39.60%, respectively. The major food group for dietary intakes of Zn, Cu, Mn, and Se was cereal, providing 8.55 mg (66.60%), 0.78 mg (59.93%), 2.09 mg (65.50%), and $16.83{\mu}g$ (32.43%), respectively. Many female university students were deficient in Mn and Se compared with the dietary reference intakes. Therefore, except for cereal, it is required to consume a diet consisted of various food sources for increasing the intakes of antioxidant trace minerals, especially animal food groups.
