This study investigated antioxidative and hypoglycemic activities of Omija for evaluation of usefulness as a functional food resource. Omija water extracts were extracted with water for 24 hr, 6 hr and 3 hr at room temperature, 60$^{\circ}C$ and 100$^{\circ}C$, respectively. Omija ethanol extracts were extracted with 60% ethanol for 24 hr and 3 hr at room temp temperature and 60$^{\circ}C$, respectively. The antioxidant properties of Omija(Schizandra chinensis Baillon) extracts prepared under different extraction conditions were evaluated by a variety of radical scavenging assays including DPPH, $ABTS^{{cdot}+}$, and nitrite and reducing power. Hypoglycemic activity was examined for $\alpha$-glucosidase inhibition using an in vitro model. The total phenolic content was also determined. Antioxidant activities of Omija were the highest in the group extracted with 60% ethanol for 3 hr. The ethanol extracts showed higher activity than water extracts. An extraction temperature was the highest in 60$^{\circ}C$. The total phenolic content extracted with 60% ethanol for 3 hr at 60$^{\circ}C$ was 530 mg GAE/100 g. The water extract extracted with water for 24 hr at room temperature showed the lowest antioxidant activity and phenolic content. $\alpha$-glucosidase inhibitory activity was the highest in the group extracted with 60% ethanol for 3 hr at 60$^{\circ}C$, followed by the group extracted with 60% ethanol for 24 hr. The results suggest that extraction of Omija by 60% ethanol for 3 hr at 60$^{\circ}C$ will be useful as a functional food resource with natural antioxidants and hypoglycemic activities.

The purposes of this study were to examine the relationships between women's social status, social participation, freedom, and clothing, and the manner in which women's clothing affected women's freedom and social participation through the centuries. The stimuli for the study were six images that were used to ask about women's perception of clothing and their social participation. The analysis of the study was used to provide descriptive statistics, frequencies, and Independent sample t-test. The study participants were 268 female college students from a central university in Korea. The participants' ages ranged from 18 to 33 years, with a mean age of 20.93. Ninety-seven percent of the participants said they usually or always were influenced emotionally, psychologically and in terms of external factors by what they wear. Approximately 60% of the women answered that women were limited to social participation by what they wear. These study results indicated that clothing for women did not just function to cover the body, but was also used as a tool to restrict women's behavior, social role, gender discrimination, and social participation.

This study examined user needs for compression pant development for women with pes planus in their 50s and 60s. A total of 355 women aged 50 to 69 participated in the survey and interview. Questions were asked if they had pes planus, the using condition of foot orthotic, inconveniences during gait, and wearing condition of compression pants. The results showed that 42 (11.8%) women had pes planus. Orthotic insole and arch support were used most frequently. The most uncomfortable aspect of foot orthotic (n=146) was that it was difficult to use unless they were going outside. Participants with pes planus responded that they felt discomfort on the inner area of propodium, metatarsus, ankle, and knee during gait. The purchase and wearing rate of compression pants were not high; however, compression pants were purchased with specific needs and purposes. Respondents mainly wore the compression pants for sports activities. M size was the most frequently worn size. They preferred high waist type leggings and there was a need to increase the compression strength of the waist, thigh, knee and ankle. Additionally, the ease of donning and doffing were discussed.

PURPOSE: The purpose of this study was to investigate the effects of the 8.5seconds cut-off of the 8-foot up-and-go test as a predictor of falling and a good discriminator of fallers and non-fallers in women in their 60s to 80s. METHODS: The final subjects of this study were 98 elderly women from six senior centers of B metropolitan city. The 8-foot up-and-go test evaluated agility and dynamic balance. The chair-stand test measured the muscle strength for of the lower body. Ankle dorsiflexion and plantar flexion were measured to assess the ankle mobility of the subjects in this study. RESULTS: The below 8.5seconds group showed significantly low values in age and high values in chair-stand (times/30 s), plantar flexion ($^{\circ}$), and K-MMSE (score) compared to the over 8.5seconds group. This group was significantly faster compared to the over 8.5seconds group. In the below 8.5seconds group, only plantar flexion ($^{\circ}$) of all the items showed significantly higher values among those in their 60s compared to those in their 70s and 80s. CONCLUSION: The 8.5seconds cut-off on the 8-foot up-and-go test as a good discriminator and predictor of falling showed differences among fall risk factors (age, lower extremity strength, cognition, and ankle mobility) in women in their 60s to 80s without having regular exercise and a fall experience over the past ones year.

This study analyzed clothing pressure, blood flow, and subjective sensations among women in their 50s and 60s while wearing commercially available yoga bra tops (YBTs). These findings could then serve as basic data for designing YBT for women in this age range. Clothing pressure and blood flow reactions were measured in seven participants wearing four commercially available YBTs. Subjective sensations of pressure and comfort were also evaluated. The calculated data were analyzed using the SPSS 24.0 statistical program. The results suggested that YBT4 exerted the lowest clothing pressure, while YBT2 and YBT3 exerted relatively higher clothing pressures. Participants' blood flow decreased while wearing YBTs compared to the control garment. The decrease of 47.3% when the participants wore YBT2 was especially significant. The results confirmed that the blood velocity rate was physiologically lower while wearing all four YBTs than when wearing the control garment. Results for subjective pressure and overall comfort confirmed that YBT2 and YBT3 exerted relatively high pressure, while YBT4 did not exert pressure.

The purpose of this study was to research on breast shape and size to suggest a brassiere sizing chart for elderly women. For this purpose 90 elderly women aged between 55 and 69 were sampled at random to review their breast types by age group, and thereby, suggest the basic measurements and production ratio of each brassiere size in reference to KS K 0070: 1999. The collected measurement data were processed statistically using the SPSS PC/WIN program for technical statistical analysis. The results of this study can be summarized as follows; 1. Analysis of Breast Measurements To find out difference among age groups, the 90 subjects were grouped into three(Group 1 ; aged 55 to 59, Group 2 ; aged 60 to 64, Group 3 ; aged 65 to 69). The results of the comparative analysis of anthropometric data from three groups show that getting older;- Various length measurements related to the drooping degree of breast were increased. It was found that the older group in their 65-69's had more drooping breasts than their 55-59's or 60-64's counterparts. Such findings suggests that older women's drooping can be corrected by a brassiere which serves to support the breasts. 2. Suggestions on a Brassiere Sizing For the basic measurements of brassiere parts for the elderly women, the correlation between underchest circumferences and cup sizes were analyzed. 3% or higher occurrences among the whole sample elderly women were included in the brassiere sizes. thus, the under-chest measurements were set at four intervals from 75 to 95, while the cup measurements were determined also at four intervals from "AAA" to "B" sizes. The resultant 6 sizes excluding the least frequent occurrences covered 73.2% of the sample elderly women actual breast sizes. As a consequence of reviewing the production ratio of each brassiere size for the women, it was found that the brassiere size of highest production ratio was "85A" (17.4%), followed by 80A (14.5%), 85AA 90A (10.1%) and 75A (8.7%) in their order.

Reducing women's bone mineral density (BMD) has close relationship to risk in osteoporosis. This study was carried out to identify bone density risk factors affecting women's BMD, and to analyze the relationship of age, between BMD and menopause, BMI, blood pressure lifestyle and dietary habits for bone health by physical measurement and questionnaires. The study subjects, 128 women living in Seoul, were divided into 4 age group; 30~39 years (17), 40~49 years (54) and 50~59 years (36) and 60~69 years (21). There were significant differences in mean height, BMI, systolic blood pressure, menache and menopause age and menopause ratio and BMD T-score among the 4 age groups. BHD was significantly decreased according to increasing age and BMI and menopause. The rate of BMD risk subjects was significantly different increasing with age and BMI. The rate of risk group were 0%, 13%, 22.2% and 71.4%, by age groups and 0%, 16.2%, 33.3% and 52.9% by BMI respectively. BMD of menopause groups was significantly decreased from 1.23 (40 years) to 1.34 (60 years). p < 0.001. Also systolic blood pressure were significantly increased from 116.5 mmHg (30 years) to 130.81 mmHg (60 years). The T-score of normal group also decreased significantly from 1.27 to 0.13 (60years) with age. There were significant negative correlation between BMD and age (r = -0.409) menopause (r = -0.346), BMI (r = -0.218) systolic blood pressure (r = -0.193), salty taste eating out (r = -0.185) (p < 0.05). There were significant positive correlation between BMD and meat fish and walking time. In conclusion, bone density decreased with age. Most of the 50 years' subjects were in risk group. BMI, menopause, systolic blood pressure, frequency alcohol consuming. To prevent osteoporosis, over 40 years needed to be educated to maintain normal weight and the improvement of eating and living habits.

The purposes of this study were to investigate actual use, design preference, and purchasing behaviors of bedding among married women in their 30s to 60s, and to determine the differences by age groups on these variables. The subjects were 623 married women and the research method was survey. The data were analyzed by descriptive statistics, cross tab analysis, multiple response analysis, ANOVA, and Duncan's multiple range test, using SPSS program. The results were as follows. First, on the actual use of bedding, the possession quantity of the bed cover and mattress was 2~4 while bedclothes and pillow was 7~8. The period of use of bedding was about 2~4 years and the frequency of washing was about 2~3 times a month. Second, married women generally preferred white and pastel tones, floral patterns, cotton fabrics, and a clean and comfortable image on bedding designs. Third, on the purchasing behaviors of bedding, married women considered functional damage and health & sanitary aspects as important purchase purposes. The most important selection criterion was fabric. Price, tactility, functionality, and manageability were also important criteria. Married women generally used the internet and store displays as important information sources, and considered bedding specialty stores as important purchase places. They generally spent about 200,000~300,000 won a year to purchase bedding. Fourth, the actual use, design preference, and purchasing behaviors of bedding showed many differences by age group. Therefore, it is needed to establish product development and marketing strategy of bedding, considering customers'age variable.

Purpose: To identify factors influencing women's intention to take hormone replacement therapy(HRT). Method: A cross-sectional survey design was utilized. A total of 116 married women aged 40 to 60 were recruited from women's groups in communities. They completed a structured questionnaire containing demographic characteristics, Orientation to Life Questionnaire, Menopausal Symptom Checklist, Health Belief of Korean Adult, Sexrole Idea of Kim, Dong-il, chronic illnesses, and a single item measuring marital satisfaction. Result: Thirteen percents of the women were currently taking HRT and 28.4% had intention to take HRT. Education, sense of coherence, and sex role attitude were related to women's susceptibility to menopause. Hysterectomy status and the level of sense of coherence explained women's perception of seriousness regarding menopause. In addition, chronic health conditions accounted for the variances of benefits and barriers to HRT. Factors influencing women's intention to take HRT were education, menopausal symptoms, and perceived benefits of HRT. Conclusion: Women's chronic health conditions, psychosocial characteristics as well as menopausal discomforts were associated with women's choice regarding HRT. Other factors related to decision making process of women's health seeking behaviors need to be explored.
