The aim of the present study was to investigate age-related differences in stepping behavior in response to sensory perturbations of postural balance. The participants for this study were 2 healthy elderly adults (mean age=76.0) and 2 younger adults (mean age=25.5). Subjects were asked to step over a 10 cm high obstacle at self-paced speed with the right limb to land on the primary target (normal step length) that is 10 cm in diameter. However, if, during movement, the light was illuminated, then the subject had to step on the secondary target (long step length). It was planned that the onset of the light would be prior to peak Fx of swing limb, between swing peak Fx and swing toe-off, and after swing toe-off. In the younger adults these secondary visual cues were provided at mean times of 240 ms (standard deviation (SD)=11), 402 ms (SD=13), and 476 ms (SD=88) following the movement onset. Corresponding mean times for the healthy elderly were 150 ms (SD=67), 352 ms (SD=39), and 562 ms (SD=115). Results showed great changes in both group and visual cue condition in Fx ground reaction forces and temporal events following the swing toe-off. Swing limb acceleration force (Fx) and stance peak Fx1 was much greater in the young adults compared to the older adults. Both young and older adults increased stance peak Fx2 in the visual cue condition compared to normal stepping. There was no difference in stance peak Fx2 between the visual cue conditions in both groups. Similarly, the time to stance peak Fx2 was much longer for the visual cue condition than for the normal stepping. It was not different between the visual cue conditions in the young adults, but in the elderly mid and late cue was much greater than early cue. In addition, time to stance peak Fx2 and swing and stance time were much longer in the older adults compared to the young adults for the visual cue conditions. These results suggest that unlike young adults, elderly adults did not flexibly modify their responses to unexpected changes in step length while stepping over obstacles.

Purpose: The purpose of this study was to investigate the level of life satisfaction and the significant factors which impact on life satisfaction of young-old (60-69 yr), old (70-79 yr), and oldest-old (80 yr or above) women. Methods: The participants for this study were 289 elderly Korean women living in the city of Daegu and Kyongpook province. The data were collected using structured questionnaires. ANOVA, Chi-square, and multiple regression with the SPSS program were used to analyze the data. Results: There were statistically significant differences among young-old, old, and oldest-old women regarding the existence of spouse, income, educational status, and religions. The model including variables related to physical, psychological, financial, and social aspects of life, explained variance of life satisfaction of elderly women differently, such as 55% of young-old, 37% of old, and 66% of oldest-old. Finally, self-esteem was the only predictor in explaining the level of life satisfaction among old women regardless age. Conclusion: Based on the findings of the study, implications for practical services for elderly women and recommendations of further study are provided. Nursing interventions should be developed to improve life satisfaction of elderly women according to age differences.

This study deals with the relation between traffic accident and urban decline. The purpose of this study is to develop the regional accident models of elderly drivers. In order to develop the count data models, 2009-2015 traffic accident data from TAAS(traffic accident analysis system) and urban decline data from urban regeneration information system are collected. The main results are as follows. First, the null hypothesis that there is no difference in the accident number between elderly and non-elderly drivers is rejected. Second, 8 accident models which are all statistically significant have been developed. Finally, common variables between elderly and non-elderly are ratio of elderly people, elderly person living alone/1,000 persons and wholesale/retail employments/1,000 persons. This study could be expected to give many implications to making regional accident reduction policy.

To find out why elderly drivers have more frequent traffic accidents on intersection than any other one, this study was conducted to examine the characteristics of elderly drivers' driving behavior on intersection using a multifaceted driving behavior indicator. To do that, the driving behavior of both young adult drivers and elderly drivers were compared and analyzed, using a graphic driving simulator. As a result, compared with young adult drivers, elderly drivers showed a poor driving performance, and a high ratio of visual scanning time on the specific direction regardless of driving situation. Also, compared with young adult drivers, elderly drivers had a high overall level of arousal, and the phasic arousal activity on the specific stimulus was low. These results imply that through the intervention which induces the change in multifaceted indicators mentioned earlier, they could be helped to drive more safely on intersection.

Objectives: This study analyzes whether the leisure activities satisfaction of elderly and older elderly patients differs with population sociology characteristics for the leisure activities services provided by geriatric hospitals, and to provide basic information to make reasonable decisions. Methods: Difference Analysis of the difference (T-test, ANOVA) in leisure activities satisfaction was conducted for the elderly and older elderly patients hospitalized in nine hospitals. Results: First, In the planning stage of leisure activity program, it is necessary to consider the tendency of men and women to prefer gender-based leisure activity service. Second, It was found that old elderly patients were more in number than elderly patients. Third, managers of geriatric hospitals in Busan and Kyungnam area should consider the needs of the patients in the planning and implementation of leisure activities and improve their leisure activity programs or develop more programs for better customer satisfaction.

The purpose of this study was to investigate the changes in walking pattern of the elderly during inclined walkway with uneven surfaces and level walking. 10 young($26.3{\pm}1.3$ years, $174.3{\pm}5.3\;cm$, $69.5{\pm}9.5\;kg$) and 13 elderly($72.4{\pm}5.2$ years, $164.5{\pm}5.4\;cm$, $66.1{\pm}9.6\;kg$) male subjects were participated in the experiment. Experiment consisted of 2 walking conditions: horizontal and inclined walkway with uneven surfaces. 3D motion capturing system were used to acquire and analyze walking motion data with sampling frequency of 120 Hz. To compare differences between conditions, kinematic variables(walking speed, stance-swing ratio, hip joint angle, knee joint angle, ankle joint angle, pelvic rotation angle) were used. Results showed that there were some changes of elderly walking pattern in inclined walkway with uneven surfaces: hip joint(adduction and rotation) and pelvic movement pattern. These changes by inclination and surface may affect gait pattern of young subjects as well as elderly subjects. However, in case of elderly it revealed more unstable gait than the young. Further study is necessary to clarify changes in walking pattern for elderly by considering various gait variables including head movement and various walkway conditions.

To examine the cognitive function of elderly, the study examined the performance of Korean normal elderly population whose age over 65 using neuropsychological instruments. It was predicted that the performance of the Korean population would be different from the U, S. mainly due to their difference in language, culture, and education. Korean elderly people from the Chungchung and Daejeon Metropolitan city(n=97) participated. Two age scores were developed: below 74 years and over 75 years. The effect of age, gender and education was examined, which yield significant age, gender and education effect. The score of DSF, DSB, TMTA, and TMTB are expected to be utilized for research purposes, such as basic, clinical, epidemiological studies, as well as practice purposes such as diagnosis and assessment of the progression of cognitive decline and dementia with MMSE-K.

This research was conducted to provide basic data for the formulation of marketing strategies suitable to the increasingly globalizing clothing market for the elderly in the fashion industry, by comparing the clothing behavior and preferences of elderly women aged over 70 years in Korea with those of women in the U.S. The 106 questionnaire responses that were collected in the U.S. and the 235 responses that were collected in Korea were used for the analysis, The major objectives of this study were as follow; 1. It was found that the elderly women of Korea utilize mostly human information as information source when purchasing clothing, whereas women of U.S. utilize mostly media information. Comfort was found to be most important factor both countries, but the Korean women considered the aesthetic aspect of clothing more important than did American women. 2. The clothing preference of Korean elderly women aged over 70 years was concentrated in young and feminine images regardless of items, so it could be seen that they had strong desire for looking young. But American elderly women showed different preference depending on items, so it could be seen that they pursue diverse images depending on clothing items and personality without concentrating in one image. The comparison of the preference style by item of elderly women over 70 years of age between Korea and the U,S. showed significant difference. Accordingly, the designs of the clothes of the Korean and American women should be differentiated and developed according to the clothes item and country.

Korea is becoming an aged society as well developed country. Accident rates of elderly workers are increased. When elderly workers injured, elderly workers are more likely to die as a result, and they take longer to recover than young workers. Thus the cost to industry per individual accident gets higher for elderly workers. If information on the occupational accidents of elderly workers could be collected and analyzed for the purpose of preventing occupational accidents, we would be able to get rid of accidents of elderly workers. The accidents of elderly workers in small manufacturing factories were considered in this study. 97 accidents, which occurred in 1995-1998, were investigated. These accidents were analyzed in terms of sex, work period, cause of accident and form of accident. The accidents of elderly workers in small manufacturing factories are numerous and are often serious and worthy of greater attention than they have received. Successful strategies for accident prevention depend on effective analysis.
