The silver generation have clothing style of optimal daily life comparing than young generation because they do not participate a specific sport event but daily- life exercise. As the human body ages, the figure of the silver generation shows different body shape because upper body changes to curved figure including the belly and waist part. Therefore, clothing characteristics for the silver generation should be considered with proper function, design and textiles to optimize body movement. This study investigated various exercise types according to motion analysis of the silver generation in order to develop the design of the active T-shirts reflecting the structural properties and providing the optimum exercise circumstance. The results to consider design needs are as followed; As the T-shirts design for the flexible exercise which required frequent movement of upper body such as bending and waist twisting during body stretching, a stretch fabric applied to the waist part considering T-shirts allowance and length to make extreme elongation and support for well-fitting appearance of the T-shirts. As the T-shirts design for the instantaneous reactionary exercise, high elastic four-way stretch fabric is applied to the part of arm hole to optimize skeletal and muscle movement for entire body and arm work. As the T-shirts design for the endurance exercise such as climbing, cycling, and walking, the shoulder line of the back part has cutting line allowance to make optimum movement of the upper body but no change of the waist part.

Osteoarthritis(OA) is a widespread, slowly developing disease with a high prevalence rate increasing with age. The most common big joints involved in OA is the knee, where the disease particulary strikes, causing difficulties in rising from a chair. climbing stairs, kneeling. standing, and walking. The primary complaints of these patients include pain, stiffness. instability, and loss of function. The purpose of this study was to assess the impact of self-reported symptoms and limited flexion, and limited extension on functional impairment in patients with knee osteoarthritis. In the data collection, a total of 206 who had visited the physiotherapy unit at six different departments of orthopedics were interviewed in K City from June to September, 2000. The results of the study summarized are as fellows: 1. There was a significant difference among different degree group of limited flexion(p<0.05). A group difference was demonstrated between <5 ${\sim}$ 15 and 16 > (F=16.21, p<0.05). In the relationship between the degree of limited flexion and the level of functional impairment, the h igher the range of limited flexion, the lower the level of functional impairment. 2. In the relationship between the degree of limited extension and the level of functional impairment, a group difference was revealed between the non-limitation group and the <10 and 11 < However, no significant difference was noted between 11 ${\sim}$ 20 and 21 >(F= 13.37, p<0.05). In conclusion, finding above suggest that functional impairment is closely correlated with limited tlexion and extenion

The purpose of this study was to determine the effect of physical activity on bone mineral density(BMD), and osteoporosis risk factors in Korean women. A convenience sample of 115 women completed the survey questionnaire which included the items of physical activity, osteoporosis risk facors, and demographic background. Distal radial BMD was evaluated using DTX-200. The data were analyzed using frequency, percentage, t-test, Pearson Correlation Coefficient, logistic regression, ANOVA, stepwise multiple regression by SPSS WIN. The sample ranged in age from 31 to 78 years(mean=47.67 old). 91.8% were married, 72.2% were housewives, and mean monthly income was 1,094,900won. Mean explain of the women was 1.21MET, and 50.4% of the women were in the physically inactive group. Brisk walking and mountain climbing were frequently cited activities. 1.8% of the subjects smoked, and 27.5% used alcohol. Average daily intake of milk was 1.17 cups and that of caffeine, 1.13 cups. Age, body weight, monthly income, BMI, education level, duration after menopause, menstration status and caffeine. intake were correlated with BMD. In the relationship between the physical activity and BMD, the physically active group showed a higher level of BMD than the physically inactive group. Significant MET decreased was noted with an age increase. In the stepwise multiple regression analysis, body weight, duration after menopause, and the number of children were identified as the most important risk factors. Conclusively, physical activity could be a beneficial effect in the reduction of osteoporosis in Korean women, considering a positive relationship between physical activity and radial BMD.

The purpose of this study was to investigate the life style, self-efficacy, and Bone Marrow Density (BMD) in osteoporosis female patients. The subjects were recruited at the four Osteoporosis Clinics. A convenience sample of 190 women completed a survey instrument which included the Osteoporosis Self-Efficacy Questionnaire, Life Style Questionnaire and demographic items. BMD of L$_4$ was measured by Dual Photon Absor photiometry. The sample ranged in age from 40 to 82 years (Mean＝60.28). Eighty-one percent were married and 14.9% were widowed. Forty-four percent lived with their spouse and children. Excercise, diet, medication, alcohol consumption, and smoking were measured to investigate the life style. Fifty-seven percent of the subjects exercised regularly. Mountain climbing, brisk walking, and free gymnastics were frequently cited excercises by the subjects in this study. Sixty percent drank one cup of milk and 34.7% had 1.13 cups of coffee in a day. Thirty-nine percent used calcium supplements, 9.5% drank alcohol, and 3.2% smoked cigarettes. Economic status and education level were related to self-efficacy. Age, economic status, and education level were related to BMD. As a life style, exercise, diet(milk, ice cream, and coffee), and medication(calcium) were associated with self-efficacy. The subjects who exercised regularly and took calcium supplements for a longer time had a higher level of self-efficacy than those who did not. Smoking and alcohol consumption had no relationship with self-efficacy. Excercise, medication(calcium), and alcohol consumption were related to BMD. The subjects who took calcium supplements for a longer time had a higher level of BMD. Alcohol consumption was not related to self-efficacy but related to BMD. The subject who drank alcohol had a higher level of BMD than those who did not drink. The amount of alcohol consumption was positively related to BMD.

Old age is often compared as climbing mountains which requires walking out of breath, yet with wider vision. And it is also likened to the estuary where the river flows slowly and broadly into the open sea. Socially, old age has been regarded as a symbol of wisdom and reflection, and elderly people often take the role of sage who leads the community. On the other hand, the dementia, gray hair and wrinkles of old age were sometimes perceived as the decline of intellect and vitality. Especially, in the digital age in which technology makes people more sensitive to physical artificiality, the evaluation of the old age becomes more complex and obscure. In other words, some elderly people can not escape from Confucious convention of the elders first, which causes the denouncement by younger generations. On the other hand, some elderly people are becoming more adaptable to the trend of young people, emerging as the new elderly people. The anti-aging movement, early adaptation of IT, bioengineering regimen also strong for the advanced age. However, as the new elderly people are active in many fields of society, they also face intergenerational conflicts in some areas where remains the overlap between young people and them due to the limited openings in economy and culture. This study is a transdisciplinary research which can be called old age humanities. First of all, this paper looks at the aspects of lifestyles and intergeneration conflicts in old age in four Korean and Western literary works about the old people, and also searches how to improve the quality of the later life of old people, Overall, this paper aims to explore the way the old people can achieve the full life with the help of intergenerational dependency through building aging humanities and new communities for old people.
