This study was conducted to investigate the mediating effects of walking days on body mass index (BMI) according to the public transportation satisfaction of middle aged Koreans aged 40-59 in Korea using the 2015 community health survey data. The purpose of this study was to provide basic data for provision of the neighborhood environment and support programs for the walking activity and promotion of daily walking activities among middle aged people. Among 228,558 individuals, 85,344 middle aged people aged 40-59 years were selected as final subjects for analysis. The data were analyzed with the open source statistics program R 3.4.1 to determine whether the number of walking days had a mediating effect on body mass index (BMI) as an independent variable. The Sobel test revealed that the number of walking days increased by B=0.010(p=.010), and that when the satisfaction with public transportation increased, B=-0.052 (p=.021), the number of walking days decreased by B=-0.038 (p=.001). To increase the number of walking days and decrease the body mass index by increasing public transportation satisfaction by increasing the use of public transportation, public transportation fare adequacy and access convenience among the public transportation satisfaction mentioned above should be improved more than the current level. It is not easy for individuals that live in small cities to reach their destination by public transportation after leaving the metropolitan area; therefore, improvement of public transportation systems is necessary to improve health.

In 2026, in ten years from now, Korea is expected to enter into a super aged society. By facing this social phenomenon, analyzing the elderlies and preparing measures are needed among society. In the transportation field, the traffic accidents which are related to the elderly pedestrians have drastically increased so that R&D projects and policy supplementations are introduced. However very few base studies on which focused on the behavior, capability, impact factors analysis of for elderly pedestrians are conducted. To determine the walking capability, this study divided the walking capability into 3 three categories - general, health and exercise. It carries out the comprehensive survey targeting 52 elderlies with the average age of 72.6 years and this survey is made up of total 12 factors in the 3 three categories. This survey also is conducted with various measuring devices and methods such as interview, National Fitness Award, SPBB, Cybex and the like for. From the 12 detailed factors, the general factors such as age, physical shape and so forth have little impact on the walking speed. However the factors that have the greatest impact on the walking speed are extensor muscle on lower limbs in the health factors and balance, coordination, and SPPB in the exercise factors. With these results, this study develops the independent walking model which can measure the walking capability of the elderly people. The developed model is expected to be utilized as the base study for elderly's walking patterns in the transportation field by examining the walking capability of the older people.

Background: The purpose of this study was to investigate the change of lower limb muscle activation according to the use of arm sling in normal subjects. Design: Cross-sectional Study Methods: Seven healthy subjects (6 males and 1 female, 25.42 years, 173.57 cm, 71.71 kg) were recruited on a voluntary basis. To measure the lower limb muscle activation during walking with and without arm sling, we used a wireless surface electromyography (sEMG) (FreeEMG1000, BTS Bioengineering, Milano, Italy). Six wireless sEMG electrodes were attached to the following three major muscle groups of the both side lower limb: rectus femoris, biceps femoris, medial gastrocnemius. All subjects wore arm sling on their right side during measurement. Results: In the stance phase, there was a significant increase in right side rectus femoris muscle activation in walking without arm sling compared to the walking with arm sling (p<.05). Additionally, In the stance phase, there was a significant increase in left side tibialis anterior muscle activation in walking without arm sling compared to the walking with arm sling (p<.05). Conclusion: The results of this study suggest that there is a significant association between the arm swing restriction and lower limb muscle activation. Therefore, it seems that it can be applied as basic data for gait training with an arm slings.

Korea is expected to enter 'Super Aged Society' in 2026. However, as walking is the very basic human right of mobility, securing safe and convenient moving of elderly people comprising the majority of transportation vulnerable is thought to be the most basic welfare, which can be easily neglected. From this perspectives, this study provides the walking characteristics of elderly people to be used in design of pedestrian facilities. The analysis of the measurements using Motion Analysis Systems shows that all walking factors of elderly people is 75% level of the younger group. Elderly group shows slower movement, reduced shoulder movement and increased ankle movement compared to the others. Also, foots are risen less and ground repulsive force is increased. Cluster analysis shows that the group of the elderly shows high variability inside the group, and 2 or 3 clusters can be formed with factors of Walking, Balance and Muscles. These walking characteristics can be used in designing pedestrian road, slope and step height of roadway facilities.
