The present study was conducted to find out whether there are some differences in plasma carnitine levels among young-, middle-, and old-aged normal Korean women. Daily food intake, body fat content, plasma lipids and carnitine levels were measured in 153 samples from 44 young (20-24 years old), 49 middle-aged (30-49 years old), and 63 old (65-85 years old) normal volunteers. The differences in concentrations of nonesterified acylcarnitine and acid-soluble acylcarnitine were not statistically significant among them. However, acid insoluble acylcarnitine (AIAC) level in plasma decreased with age. Moreover, total carnitine (TCNE) level in the young group was significantally higher than in old and middle-aged groups. Body fat content in the young group was significantly lower than in old and middle-aged groups. Plasma total cholesterol increased with age and triglycerides in the old group were significantly higher than in young and middle-aged groups. These results suggest that the higher levels of AIAC and TCNE in the young group may be a reflection of their lipid metabolic state, which is different from middle-aged and old groups.

Age-dependent changes in body fat can often be observed in normal population. A series of indirect body fat estimates, such as hydrodensitometry, Bioelectrical Impedance Analysis(BIA), and anthropometry equation for body fat, have been developed. The BIA made it possible to analyze body fat mass more related to hydrodensitometry than anthropometry. This study is to compare the body composition analysis between bioelectrical impedance analysis(BIA) and anthropometric measurements of women. The subjects were a group of Daejeon residents including 32 young-aged women($21.50{\pm}1.44$), 30 middle-aged women($50.33{\pm}5.27$), and 40 old-aged women($69.22{\pm}5.74$). We used BIA(inbody 3.0, Biospace Korea) to determine body fat and other body composition. We also measured weight, height, circumference for 12 parts, and skinfold thickness for 9 parts of all subjects' body. The results are as follows: The subjects' height by the age group were $161.74{\pm}0.94cm$ in the young-aged women, $154.16{\pm}1.09cm$ in the middle-aged, and $148.60{\pm}0.78cm$ in the old-aged respectively. BMI were, in order, $21.68{\pm}0.49,\;22.87{\pm}0.89,\;and\;23.85{\pm}0.55$. Relative body fat determined by BIA was, also in order, $29.06{\pm}0.92%,\;26.35{\pm}1.02%,and\;29.35{\pm}1.07%$. Circumference and skinfold that showed the highest correlation with body fat by BIA was waist in the young-aged(r=0.738) and bast in the middle- and old-aged(r=0.844, r=0.804), and triceps in the young-and old-aged(r=0.538, r=0.798), and subcostal in the middle-aged(r=0.872). Body fat Estimations by BIA were the highest correlation with Caucasian women's equation(r=0.588) in young-aged women, Siri's equation with Durnin & Womesley's body density measurement(r=0.875) in middle aged women and Caucasian women' equation(r=0.872) in old aged women. We need to develop specific anthropometric equations based on sex and age to determine body fat.

The purpose of this study was to analyze the factors influencing life satisfaction in widowhood among older females. Using the sixth Korean Retirement and Income Study (KReIS) supplementary survey data, a total sample of 1,471 women aged 65 or older whose spouse had died were selected, divided into 508 young-old (65-74), 745 middle-old (75-84), and 218 oldest-old (85+). Then, factors influencing the life satisfaction of these three groups were analyzed, based on a combination of perceived health and interpersonal satisfaction levels. It was found that among the young-old group, a higher level of subjective health perception indicated by monthly income and material support and interpersonal satisfaction linked to more frequent participation in community gathering combined for an overall higher level of life satisfaction. For the middle-old group, higher life satisfaction was provided by monthly income, informational support, and material support for subjective health perception and no diseases for interpersonal satisfaction. The oldest-old group with higher life satisfaction referred to monthly income for subjective health perception and no experience in donation activities for interpersonal satisfaction. Based on these findings, this study provides implications for policy and practice to improve the life satisfaction of elderly women who have experienced their spouse's death.

The main objective of this study was to investigate the patterns of glucosinolates (3-butenyl isothiocyanate, total glucosinolates) in different parts of young seedling and seeds on Korean Chinese cabbages 55 days and Winter pride cultivars. For determination of glucosinolates, two cultivars of Chinese cabbages seeds and different parts of 1-day-old, 3-day-old, 5-day-old, and 7-day-old seedlings were used for analytical sample preparation provided with an anion exchanges column, and measured by GC and UV-Visible Spectrophotometer. 3-Butenyl ITC concentration was the highest in the cotyledon and the hypocotyl parts of 55 days cultivar seedling. In the cotyledon part of Winter pride cultivar seedling, 3-butenyl ITC amount was increase to 3-day-old seedling and then reduced. The cotyledon of 55 days cultivar contained the highest concentration of total glucosinolates while those were increased in the hypocotyl and decreased by degrees in the root. Total glucosinolates amounts were increased to 5-day-old seedling and then decreased in the cotyledon and the hypocotyl parts of seedling on Winter pride cultivar. There was no significant difference in the root part. In the seeds, both of 3-butenyl ITC and total glucosinolates, 55 days cultivar concentration was higher than Winter pride cultivar. The study has shown the variability in 3-butenyl ITC and total glucosinolates concentrations among cultivars, growth stages, and parts.

The purpose of this study was to design functional clothing based on the physical characteristics of old women. The subjects of this experiment were 5 healthy old women and 5 college women. While the subjects were exposed to the circumstances of $28{\pm}0.5^{\circ}C$ and local heating at 7 areas (chest, abdomen, back, loin, hand, thigh and instep), their skin temperature, physiological reaction and psychological reaction were determined. The conclusions about the effects of local heating are as follows : 1. Skin temperature before heating was in the order of head-neck> trunk> upper limbs> lower limbs (Group A: old subjects) and head-neck> trunk> lower limbs> upper limbs (Group B: young subjects). 2. The heating pad was attached and detached for 30 minutes each. The sharpest rise and fall were recorded at 5 minutes with the pad on and off. Both groups had great changes in the body parts near trunk. 3. With the pad on and off, both groups showed no change in body temperature, blood pressure, and pulse rate. 4. Concerning the pervasive effects of local heating on whole body skin temperature, loin heating greatly increased other body parts in Group A. In Group B, the effects were large in heating chest, abdomen, back, loin, and thigh. 5. The loin part of old women has the greatest pervasive effect of local body heating.

This study is to help produce highly comfortable and wearable and footwear based on the establishment of basic data for manufacturing elderly footwear patterns and products. For this, a survey of 207 women in their 20s and 60-70s was conducted to identify the wearing of shoes, inconvenience areas, purchase practices and footwear preferences by age group. The results are as follows. First, the average age of the young female group was 22.5 years old, the elderly female group was 68.8 years old, and the average shoe size was 236.3 mm for the young female group and 238.3 mm for the elderly female group. Second, young women wore shoes for a longer time than elderly women, resulting in swollen and numb legs, hardened soles, uncomfortable toes and sore heels. However, elderly women felt more uncomfortable wearing footwear than young women. They suffered pain in the joint area, heal and toe areas as well as had more toe deformations due to aging. Third, all age groups preferred athletic shoes and loafers as well as purchases from footwear brand stores and department stores. The elderly spent more money on shoes, longer time to buy and valued the feeling of wearing, whereas the young considered design first. Fourth, both age groups prefer low-heels and natural leather, the young preferred to wear various types of shoes; however, the elderly are found to desire shoes that are comfortable and stable in both form and wearing.

The purpose of this study is to analyze the middle-aged British women's apparel purchase behavior. The results of this study can be used to present the tendency of Korean middle-aged women's apparel purchase behavior when they become the old-aged by comparing and analyzing the British women's purchase behavior. We found that they prefer to choose and purchase their clothes by their own decision-making and search for actively the new brands for old age. Strong willingness was showed that their level of consumption amounts for clothing would be the same level between middle-aged and old-aged. It was also presented that they like to see a old-aged fashion model for fashion advertisement rather than a younger one and prefer to use the expression of 'mature' rather than a stereotypical expression such as a silver, gray and gold. The segmentation of fashion market by age can not be simply standardized. We expect that the propensity for clothing purchase behavior pattern of middle-aged women will not be changed and keep the same tendency by the time of their old-aged. We expect that this research results can be used as a basic material for another study and setting up the product developments and marketing strategies.

The present study was performed to investigate the effect of aging on muscular activity of older subjects under the condition of fixed load muscle contraction. SEMG signals were recorded from old (46 women) and young (45 women) groups performing sustained isometric elbow flexion contraction with a fixed load during 30 seconds. Linear regression and mean square error (MSE) analysis with four characteristic variables (ARV, RMS, MDF, MNF) were used to compare the age-related difference (of local muscle fatigue and fluctuation of the amplitude and frequency) in the SEMG signal. The main results can be summarized as follows: During sustained muscle contraction with a fixed load: i) the MSE values of amplitude (ARV, RMS) and frequency (MDF, MNF) variables were more than 30% higher for the young than for the old adults; ii) the measures of local muscle fatigue (slope of the MDF and MNF) indicated greater fatigue in the old; and iii) the rate of increase of the SEMG amplitude was higher for the young than the old.

Purposes : As the population of old people has increased by the improvement of medical techniques, the concern on degenerative diseases has increased gradually. Especially the researches of osteoporosis have been carried out in view of prevention and treatment. But there wasn't any research related with Sasang Constitution. So we investigated the relation between Sasang Constitution and BMD(bone mineral density). Methods : Authors measured BMD and BMI(body mass index) of healthy women. We devided our subjects into Young age group and Old age group, and analyzed the data of Sasang Constitution subgroup. Results : 1. BMD of Taeumin was higher than those of Soyangin and Soeumin in Lumbar spine and Femoral neck in both Young and Old age group. In Old age group, there were significant differences in Taeumin vs Soeumin, and Soyangin vs Soeumin in BMD of Lumbar spine 2. BMI of Taeumin was higher than those of Soyangin and Soeumin in both Young and Old age group. In Young age group, there were significant differences in Taeumin vs Soyangin and Taeumin vs Soeumin. In Old age group, there were significant differences in Taeumin vs Soyangin, Taeumin vs Soeumin and Soyangin vs Soeumin. Conclusion : BMD and BMI of Taeumin was higher than those of Soyangin and Soeumin.

Purpose: This study aimed to compare self-care behaviors and depressive symptoms between the young old (65-74 yr) and the old-old (75-84 yr) in low-income women with hypertension. Methods: This study used a descriptive research design. The subjects of this study were 136 elderly women over 65 yr living in D city. Data was collected from September to December 2007 through personal interviews using a questionnaire. The collected data was analyzed using the SPSS WIN 12.0 Program. Results: Self-care behaviors, functional status, and number of medications showed a significant difference between young elderly and middle elderly. There was a negative correlation between self-care behaviors and depressive symptoms. 52.2% of variance in self-care behaviors of young elderly and 76.8% of variance in self-care behaviors of middle elderly were explained by depressive symptoms, number of medications, and functional status. Conclusion: It is necessary to manage depressive symptoms to improve the self-care behaviors of low-income elderly with hypertension. Depressive symptoms need to be considered in planning hypertension programs for low-income elderly women.
