Purpose: The purpose of this study was to identify the mediating effect of depression in the relationship between muscle strength of extremities and falls among community-dwelling elderly. Methods: Two hundred forty-seven participants were recruited from a public health center, a hall for the aged and a school for the aged in B city. Face-to-face interviews were conducted using questionnaires from May to September of 2007. Data was analyzed with descriptive statistics, Pearson correlation, and multiple regression using the SPSS WIN 14.0 program. Results: There was a significantly negative relationship between muscle strength of lower extremities and falls, muscle strength of left upper extremity and falls, and muscle strength of right upper extremity and falls. Depression positively correlated with falls. Depression showed mediating effects between muscle strength of extremities and falls. Weakness of muscle strength of extremities increased depression and the increased depression increased the frequencies of falls. Conclusion: For the effective management and prevention of community-dwelling older adults' falls, exercise programs including depression-decreasing strategies should be established. These exercise programs can decrease depression which is the mediator role between the degrees of muscle strength of extremities and falls.

In Korea, as the aging phenomenon accelerates, the problem of traffic accidents related to the elderly is continuously emerging. Efforts to improve this are being implemented, but unfortunately the results of these effects are not clear. Therefore, in this study, the effect of traffic characteristics and incentive policies on the return of driver's licenses of elderly drivers was reviewed. As a result of the analysis, it was confirmed that the intention to return the driver's license was low in the case of men, older people, those with low dependence on public transportation, those who undertook long driving hours, and those who took frequent trips. On the other hand, financial incentives were found to play a positive role with regard to the intention to return the driver's license. However, the effect is expected to be insignificant for those with a low intention to return the driver's license. As a result, under the current policy, it is predicted that there is a limit to improving the social problems caused by elderly drivers, meaning that it is necessary to review approaches that induce the return of their driver's licenses.

Purpose: This study was conducted to investigate the effects of a cognitive behavior program on cognition, depression, and activities of daily living in elderly with Cognitive Impairment. Method: The research design was a nonequivalent control group pretest-posttest design. There were 21 subjects in the experimental group and 19 in the control group among 40 senior residents in a Hall for the elderly in the city of S. The subjects scores ranged from 15 to 23 on the MMSE-K(Korean Version of Mini-Mental State Examination) over age 65. The length of time for data collection and intervention was from Jun 26 to September 1, 2006. The cognitive behavior program consisted of 'Facing problem behavior', 'Searching for a coping skill', and 'Training in the coping skill'. It was applied to the experimental group twice a week, fifty minutes per session for six weeks. Result: Cognition(t=-4.232, p< .001) and IADL(t=-2.939, p< .01) in the experimental group were significantly higher than those of the control group. Depression in the experimental group was significantly less than the control group(t=3.870, p< .01). However, ADL in the experimental group was not significantly higher than the control group. Conclusion: These findings confirmed that a cognitive behavior program contributed to improving cognition and IADL, and to reducing depression in the elderly with Cognitive Impairment.

The purpose of this study is to search how to promote health and improve nutrition and health care of the elderly people in rural area. Behaviors for health promotion and habits against health risk were surveyed. Dietary management was analyzed for surveyed nutrient intake by 24 hr -recall method. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire for health behavior and dietary management was carried out by trained interviewers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Characteristics of the elderly people were 61-74 year-olds (68.2%), elementary school educated (78.4%), with spouse (51.7%), monthly living cost of 500-1,000 thousand won(43.4%), and monthly pocket money of 50-100 or 100-200 thousand won(33.5%, 26.5%). 41.4% of the subjects checked up medical examination regularly. The alcohol drinking status was significantly different according to gender: high no-drink rate of female (52.5%) and low no-drink rate of male (25.6%). Kinds of disease were different according to gender: higher proportion of cardiovascular disease(46.3%) and diabetes mellitus(8.1 %) in male and joint lumbago neuralgia(44.4%) and osteoporosis(8.6%) in female. Gastrointestinal complaints were nausea (69.0%) and chronic indigestion (17.8%). Constipation (12.0%) and vomiting (4.3%) were more frequent in female. Dietary management was good (3 meals per day: 93.4%., dining with family: 72.4%, regular mealtime: 72.4%, and 3-4 times of snacks per week: 44.9%) except side dish taking of 3-4 kinds only. However, almost one-third of the female elderly ate alone (30.6%) which was well compared with one-fifth of the male (19.7%). And food and nutrients intake were not significantly different according to gender except that male elderly's intake of energy and protein was lower than that of female's. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some female elderly had some difficulties with Instrumental Activities of Daily Living (IADL) like working at home, using transport, and going shopping. These results suggest that low quality of life linked with low economic status of the rural elderly and that congregate meal at village hall would be required for the female elderly eating alone. For the undernourished male elderly, it would be needed to provide snacks and to establish nutrition and health surveillance system.

The purpose of this study was to study the performance of volunteer work for the elderly from the perspective of self-efficacy and self-extension of the elderly, not from successful aging or productive aging. Through this, the research aims to confirm the expansion of internal growth and self-sufficiency that can occur in old age, and to provide an opportunity to re-examine one's life in old age. In order to verify the purpose of this research, questionnaires were distributed to 300 senior citizens who participated in volunteer activities at the City Hall and the District Office of Busan Metropolitan City over a period of three months from September to November 2018 and used the data from 266 questionnaires for the study, excluding the 34questionnaire answered unfaithfully. The results of the study are as follows. First, the motivation for volunteering activities (value function, social function, understanding function) of the elderly has a positive effect on self-efficacy. Second, the motivation for volunteering activities (value functions, social functions, understanding functions) have a positive effect on self-extension. Third, it has been shown that the elderly's sense of self-efficacy (self-regulation efficacy, confidence) has a positive effect on their self-extension. Fourth, it was found that self-efficacy has a mediated effect on the motivation of the elderly to participate in volunteer activities and the relationship of self-extension. This study identified the relevance of the motivation for volunteering activities of the elderly to influence their effectiveness and self-extension. In particular, the research suggests practical and policy measures for the revitalization of volunteer activities of the elderly by providing a new perspective on the welfare of the elderly by utilizing parameters of self-efficacy, a psychological and social concept for the elderly.

The purpose of this study was to evaluate the effects of bridging stabilization exercise on balance ability and gait performance in elderly women. The subjects of this study were thirty-one elderly women over 65 years old in HongSung-Gun Senior Citizen Welfare Hall. The subjects were randomly assigned into one of three groups (trunk stabilization exercise on the mat, whole body vibration, and Swiss ball) and participated in each exercise program three times a week for 4 weeks. Each exercise began in the bridging position. The dynamic balance and gait were measured by limit of stability area using force plate, Berg Balance Scale (BBS), and Timed Up and Go Test (TUG). The results were as follows: 1) The limit of stability in three groups increased significantly in anterior-posterior and medial-lateral lean after 4-weeks intervention (p<.05). 2) There were no significant differences in the limit of stability among three groups after 4-weeks intervention (p>.05). 3) The BBS and TUG in three groups increased significantly after 4-weeks intervention (p<.05). 4) There were significant differences among three groups in BBS. Post-hoc test showed that Swiss ball exercise group was significantly higher than the mat and whole body vibration groups. 5) There were no significant differences TUG among three groups after 4-weeks intervention (p>.05). In conclusion, this study suggested that 4 weeks of the bridging stabilization exercises were effective on balance and gait in all three groups. Particularly Swiss ball exercise group showed higher improvement than two other exercise groups (mat, whole body vibration group).

The purpose of this study is to provide information searching for health promotion, nutrition improvement, and health care of the impaired elderly by ADL(Activity of Daily Living) and IADL(Instrumental Activity of Daily Living). The subjects were divided into the Assistant Needed Group and No Assistant Needed Group for living in line with the responses of ADL(10 items like dressing, washing, move etc.) and IADL(10 items like housekeeping, using transportation, shopping, Phone call etc.). Survey was made for health behavior, health risk habit, dietary management status and diet intake by 24 hr-recall and questionnaire method. 242 subjects were collected in 12 cities or Gun districts in Gyeonggi Province, S. Korea. Survey was carried out by regional home extension workers using interview method. Statistical analyses were made using SAS (Version 8.1). Chi-Square Tests and General Linear Models. The subjects of impaired ADL elderly was 26.5% and it composed 30% of the total male and 22.2% of the total female. The demographic status of the impaired ADL elderly showed no difference from that of the normal elders, elementary school educated (73.4%), with spouse (43.8%) or with adult children(37.5%), using monthly living cost of 500-1,000 thousand won(35.9%). Mean age was 74.05 years compared to 72.25 years of normal elders. However, there was no significant difference from the normal and impaired ADL group, regular exercise(60.0%), with walking (90.0%), no-smoke(54.7%) and no-drink(48.4%). Kind of disease was not different from the one in impaired and normal group, with cardiovascular disease(32.3%), with diabetes mellitus(8.1%), joint lumbago neuralgia(32.3%) and osteoporosis(9.7%). Gastrointestinal complaints of the impaired ADL group were nausea(57.8%), chronic indigestion (23.4%), constipation (14,0%) and vomiting(3.7%). Sleeping time required for the impaired was longer than that for the normal group by 10hours(4.7%) or 8-10hours(20.3%), which consisted 1.7% and 16.6% respectively. Nutrient intake of the impaired ADL group was low compared to normal range elders: Energy(1260kca1), Protein(52.75g). There was gender difference in nutrient intake; the male impaired group showed no significant difference from the normal group but it was significantly lower in female impaired group. These results suggest that low quality of life and low economic status of the impaired ADL elderly require congregate meal in village hall to cover the lack of side dishe variety. And nutrition education program including community assistance would be required for the impaired ADL elderly together with the sufficient food and exercise practice. By operating nutrition education program, the impaired ADL elderly would maintain more enhanced quality of life and ameliorate the ADL capability.

In considering the issue of safely during emergency building evacuations, it is important to be able to make accurate predictions about evacuation conditions and to be able to assess safety levels. Simulation techniques are often used to make predictions regarding evacuation conditions. The two main types of prediction models are crowd flow models and discrete models. We have developed an evacuation simulation system based on the discrete model which attempts to address the implementation problems of existing evacuation models. Our model incorporates characteristics such as evacuee profiles and spatial considerations, and is capable of dynamically predicting the behavior of individual evacuees. The simulation system is primarily designed for buildings in which many people are incapacitated and require helpers in order to evacuate, such as hospitals and facilities fur the elderly. We show the results that the evacuation simulation system was used to perform two trial simulations.
