South Korea, a rapidly ageing country, faces increasing dementia rate as the incidence of dementia increases with ageing. Service design is an effective method to develop dementia service by visualizing and specifying intangible forms of service. The Design Council in the U.K. carried out dementia solution projects such as 'living with dementia' in 2011 and 'transform aging' in 2016, introducing successful services and innovative products. Seeking useful implications, this paper explores the concept and method of service design focusing on the U.K. cases. To suggest solutions on dementia, effective strategies should be set up on the basis of service design, which embodies various stake holders' cooperation and partnership.

This study is a qualitative analysis that conducted a focus group interview to analyze the experiences of daily life of the elderly living alone and their chronic diseases management, and to explore the meaning, nature, and difficulties associated with. The subjects of this study were elder who lives alone without cognitive impairment and over 65-year-old. There were total 31 people and divided into 5 groups and they had 60 minutes interview. By this study, there were four themes of 'difficulties of daily life', 'suffering from chronic diseases', 'fear of the future', 'acceptance of life'. In conclusion, the elderly living alone felt difficulty in daily life due to physical aging and chronic illnesses, and they felt that they were accepting life at the same time while feeling the fear of the future situation. Therefore, in order to improve the life satisfaction and life quality of elderly people living alone, it is necessary to provide institutional devices that enable daily life such as meals and laundry to be maintained and to develop of an intervention program in order to maintain physical health. In addition, an intervention program should be developed to reduce the fear of future uncertainty and positively accommodate the life.

Both cardiovascular diseases caused by decreased body composition and arterial compliance and falling induced by loss of muscle mass are frequent occurrences in the elderly. Therefore, elderly people are advised to perform elastic band resistance exercises to improve their body composition and arterial compliance. Thus, the purpose of this study was to examine the effects of 12 weeks of elastic band resistance training on the body composition, arterial compliance and falling index in elderly females (> 65 years). The elastic band resistance exercise program was administered 3 times per week for 60 minutes each time for 12 weeks. In addition, the exercise intensity was set to 11-14 on the Borg scale (6-20). Before and after the training period, the body composition (body weight (BW), muscle mass, % body fat, body mass index (BMI)), arterial compliance (ankle brachial index (ABI) and pulse wave velocity (PWV)) and risk of falling index were determined. (After the program?), the BW (p=.003), BMI (p=.002), PWV (p=.017) and risk of falling (p=.037) in the exercise group were significantly reduced, whereas the BW (p=.009) and BMI (p=.009) in the control group were significantly increased. In conclusion, the body weight, BMI and arterial compliance of elderly females were positively changed by the elastic band resistance training. Thus, the elastic band resistance exercise may be useful for elderly people to prevent metabolic syndrome and cardiovascular diseases and to reduce their risk of falling.

Patients with disabilities from various reasons such as disasters, injuries or chronic illness or elderly with limited body motion range due to aging are recommended to participate in rehabilitation programs at hospitals. But typically, it's not as simple for them to commute without help as they have limited access outside of the home. Also, regarding the perspectives of hospitals, having to maintain the workforce and have them take care of the rehabilitation sessions leads them to more expenses in cost aspects. For those reasons, in this paper, a home-based remote rehabilitation system using motion recognition is developed without needing help from others. This system can be executed by a personal computer and a stereo camera at home, the real-time user motion status is monitored using motion recognition feature. The system tracks the joint range of motion(Joint ROM) of particular body parts of users to check the body function improvement. For demonstration, total of 4 subjects with various ages and health conditions participated in this project. Their motion data were collected during all 3 exercise sessions, and each session was repeated 9 times per person and was compared in the results.

Purpose: This study examined the association between the serum 25-hydroxyvitamin D concentration and the cognitive functions in Korean elderly. Methods: The subjects were 393 adults aged 60 years or older who participated in the Yangpyeong cohort between July 2009 and August 2010. The subjects were classified into deficiency, insufficiency, or adequacy groups according to the serum 25-hydroxyvitamin D concentration diagnostic criteria suggested by the US Institute of Medicine (IOM). The cognitive function was assessed based on the Korean version of the Mini-Mental State Examination (MMSE-KC). The dietary intake was assessed using the quantitative food frequency questionnaire with 106 food items. Results: The proportions of deficiency, insufficiency, or adequacy in serum 25-hydroxyvitamin D were 6.6%, 44.5%, and 48.9%, respectively. The serum 25-hydroxyvitamin D concentration was significantly higher in men than in women and in outdoor workers than in other occupations. The adequacy group had higher MMSE-KC scores than the other two groups, but not to a significant degree. The proportion of cognitive impairment tended to decrease with increasing serum vitamin D concentration to deficiency, insufficiency, and adequacy (p for trend = 0.029). The deficiency group had a 2.28 times higher risk of cognitive impairment than the adequacy group, but the difference was not statistically significant (OR, 2.28; 95% CI, 0.18 ~ 1.07, p for trend = 0.119). Conclusion: The serum vitamin D concentration tended to be associated with the cognitive function in elderly Koreans living in rural areas. To confirm the associations, further longitudinal studies with large samples were required.

The life expectancy of people has been steadily extended due to the improvement of living standards and the development of medical technology. Besides, the low birth rate and long life expectancy decrease the youth population while the elderly population is steadily increasing. Many elderly people have enough time and financial allowance, and the interest in health care is increased all over society. There are also increasing numbers of elderly people who exercise lightly in the playgrounds and parks such as running and walking. Outdoor fitness equipment that can be easily seen in neighbourhood parks, public spaces, etc. can be good health promotion tools that can be easily accessed in the daily life of the elderly. Outdoor fitness equipment Description Signs require a design that takes into account the declining vision of older users. Proper design is also important for the prevention of safety accidents in use. The purpose of this study is to find out the perception of the elderly about outdoor fitness exercise equipment sign system and to find the problem of recognition. To do this, we conduct user observation and interview surveys for the elderly. As a result, the emphasis of the caveat or problems with the size of the writing were pointed out, and it was necessary to explain the picture rather than the text. Also, there was a high demand for refraining from using foreign words, using universal words and including motor effects in signs. Based on the results of the user observation and interviews, we propose guidelines for the use of outdoor exercise equipment.

As people age and their physical functions are declined, they stay longer in the home, thus being more affected by the home environment. Many studies have shown the association between the home environment and health. However, little is known about the effect of the home environment on disability and depression of older people with functional limitation. This study, therefore, aimed to examine the moderating effect of the home environment on the pathway between walking limitation and instrumental activity of daily living(IADL) disability, and the relationship between IADL disability and depression. We performed logistic regression and multiple linear regression analyses with data on 3,027 participants from the 2018 Seoul Aging Survey. As results, first, older people who lived home with poor conditions showed a higher risk of walking limitation(OR=1.487, 95% CI: 1.250 - 1.770), IADL disability(OR=1.594, 95% CI: 1.303 - 1.949), and depression(OR=1.943, 95% CI: 1.553 - 2.430). Second, the home environment moderated the relationship between walking limitation and IADL disability. Older people with walking limitation who lived in poor housing condition experienced more IADL disability than others. Third, after controlling for walking limitation, the home environment had significant moderating effect on the relationship between IADL disability and depression. Elderly with IADL disability living in poor home experienced higher risk of depression. Based on these results, the study suggests the necessity of home modification intervention targeting functional limitation of older adults as strategy for preventing disability and depression, and enabling aging in place.

This study is attempt to submit a basic material to help the efficient nursing management which supports and to understand the alienation which they percieve social-psychologically and physical aging bringing about the phf·sical powerlessness, to understand the old people in hospitals and in community and should build up their health. The data collection of the study which has been done on Sept. 7 to Sept. 20, 1986 is objected to 300 people of 65 years old of age or more of male and female who are staying at home. Analysis of the Data was done by use of percentage, t-test, ANOVA and Pearson Correlation Coefficients. The results of study are summerized as follows: 1. According to each age group of old people(p= .0008), family living together concreteness (p=.0000), the level of education (p=.0020), how much they are participating in leisure activity (p=.0001), whether they have mate or not (p=.0000), whether they have religion or not (p=.0000), the level of alienation showed difference statistically. Also, according to sex (p=.4315), whether they have income or not (p=.1197), the level of alienation did not show any difference statistically. 2. According to each age group of old people (p=.0000), family living together concreteness (p=.0060), the level of education (p=.0000), sex (p=.0000), whether they have mate or not (p=.0000), whether they have religion or not (p=.0067), whether they have income or not (p=.0000), the level of physical aging showed difference statistically. Also, according to how much they are participating in leisure activity, the level of physical aging did not show any difference statistically (p=4879). 3. The level of alienation and physical aging in old people had positive correlation (r=.5436, p<.001). From the above result, the level of social, psychological alienation and physical aging showed high for the old who had no mate, no religion, low in their educational level, living separately' with the family and for those who do not participate much in the leisure activities, The old people who feel the social, psychological alienation can expedite the physical aging and physical aging can be result from social psychological loneliness and alienation. Therefore, for the successful aging of the old people in the community with these weak points, we should provide them with physical and emotional, psycho-logical support and care in the basis of understanding in socialization process and the character of the physical functional change.

Driving behaviors are reported to be vulnerable to safe driving in unexpected situations or driving in the city due to deterioration of physical and cognitive functions in elderly drivers. The purpose of this study was to investigate the difference in driving behaviors according to age of self-drivers and to identify changes in physical function related to driving caused by normal aging. The subjects of the study included 75 healthy adults (21 persons aged 20-39 years, 40 persons 40-64 years, 14 persons 65 years old) who were self-driving and possessed a driver's license. Data included sex, dominant hand, medication, exercise, age, and driving time obtained by a self-reported questionnaire. In addition, this study measured steering, acceleration and braking using a Driver Test Station. Results of the study showed there was no significant difference in power test according to age group, but the total time of the timer test and the emergency brake test significantly differed according to age. The timer test and emergency brake test were completed fastest in young adults between 20 and 39 years old and completed slowest in elderly people 65 years old or over. Based on our study results, it is suggested that normal aging affects the perceptual-cognitive processes associated with driving behaviors.
