The purpose of this study was to determine the effects of line dance programme on the balance ability during walking to reveal the exercise intervention for fall prevention. A 12-week line dance programme was applied to 18 elderly females who aged more than 65 years in the community. Balance ability during walking was evaluated by the range of center of pressure(cop), the velocity of cop, and free torque that calculated on the basis of ground reaction force data. The range and velocity of cop in the anterio-posterior were significantly reduced after performing(p<.01, p<.05, respectively), but change in those of cop in the medio-lateral and free torque were not found. It was demonstrates that 12-week line dance programme allows more effective in anterio-posterior stability of walking. It was suggested that the effect of fall prevention exercise should be studied more associate with fall frequency as future study.

This study examined the effects of robot-assisted therapy on the motor and functional recovery of the lower limbs in 53 subacute stroke patients. Robot-assisted therapy was performed using Lokomat? (Hocoma AG, Zurich, Switzerland) for thirty minutes per day, five times a week for four weeks. The outcome measures used were the Fugl-Meyer assessment, Motricity index(MI), Functional ambulation category(FAC), Berg balance scale(BBS) for gait function and balance ability, 10m walking test, K-Modified Barthel Index(K-MBI) for the activities of daily living and Mini mental state examination (MMSE), and Beck's depression inventory(BDI) for depression. All patients recruited underwent these evaluations before and after the four week robot-assisted therapy. For the evaluation, the somatosensory evoked potentials were used to assess the functional recovery. Robot-assisted therapy on the lower limb after subacute stroke showed improvement in motor strength, gait function, and the activities of daily living. All changes in terms of MI, FAC, BBS, and K-MBI exhibited a statistically significant difference after the four weeks robot-assisted therapy. The somatosensory evoked potential result showed a correlation with the MI and K-MBI. Robot-assisted therapy is believed to facilitate the motor and functional recovery of the lower limb in subacute stroke patients.

This study compared the utility of walking aids, and activities of daily life depending on the ability of people with mobility disabilities to use walking aids. Data were extracted from the Korea Welfare Panel Study in 2014. Data of 435,947 individuals were analyzed using chi-square and t-tests. The findings from this study showed that disabled persons who cannot use walking aids independently were more likely to have a severe disability level and a lower level of daily activities than the independent group. The level of social participation and leisure activities were also significantly lower in the dependent than the independent group. Therefore, walking aids should be tailored for individuals depending on their level of independence for using walking aids.

The pedestrian traffic flow has more complicated microscopic features than vehicular traffic flow. Without any designated lanes or any guidance, pedestrians naturally move and change their routes in two dimensional domain with ease. Thus the assessment of pedestrian comfort level should be considering the microscopic features of pedestrian flow. This study is aimed at developing pedestrian comfort criteria based upon pedestrian flow simulation model. This study suggests three criteria to determine pedestrian comfort level; the deviation of route, the acceleration of walk, and the number of collision. Each criterion, which can address the unique walking patterns of pedestrian flow, is represented as each different function with respect to traffic flow rate. The criteria can be the additional indicators to determine the level of service of pedestrian flow together with traffic flow rate and walking speed.

The purpose of this study was to examine the effects of treadmill exercise on the aerobic function of dance majors in their 20s. The subjects consisted of 10 female Korean dance majors in their 20s as an experimental group and 10 normal female college students as a control group, and both groups conducted treadmill gait training. Their heart rate recovery (HRR), maximal oxygen uptake (MOU), maximal voluntary ventilation (MVV), and lactate recovery rate (LRR) were measured before and after the experiment. The comparison of changes in the subjects' aerobic function before and after the experiment showed that the experimental group gained more significant effects on HRR and LRR than the control group. Therefore, treadmill gait training may help Korean dance majors to improve their basic physical strength by enhancing their aerobic function, and the findings of this study are likely to provide basic data to support scientific exercise prescriptions.
