Background: The method of measuring the walking function of patients with chronic stroke differs depending on patients walking capability and environmental conditions. Objects: This study aimed to demonstrate the influences of walking capacity and environmental conditions on the results of short- and long-distance walk tests in patients with chronic stroke. Methods: Forty patients with chronic stroke volunteered for this study, and allocated to group-1 (<.4㎧, household walking, n1=13), group-2 (.4∼.8㎧, limited community ambulation, n2=16), and group-3 (>.8㎧, community ambulation, n3=11) according to their walking capacity. The 10-meter walk test (10MWT) and 6-min walk tests, (6MWT) were used to compare the short- and long-distance walk tests results, which were randomly performed under indoor and outdoor environmental conditions. Results: The comparison of the results obtained under the indoor and outdoor conditions revealed statistically significant differences between the groups in the 6MWT and 10MWT (p<.05). Post-hoc tests’ results showed significant differences between groups-1 and -2 and between groups-1 and -3 in the 10MWT, and between group-1 and -3 in the 6MWT. Furthermore, in group-2 the 10MWT and 6MWT results significantly differed between the indoor and outdoor conditions, and the values measured under the indoor and outdoor conditions significantly differed between 10MWT and 6MWT (p<.05). Group-3 showed a significant difference in 10MWT results between the indoor and outdoor conditions (p<.05). Conclusion: These findings suggest that the results of the short- and long-distance walk tests may differ depending on the walking capacity of patients with chronic stroke and the environmental condition under which the measurement is made, and these effects were greatest for the patients with the limited community ambulation capacity.
해사안전분야 국제협력사업을 성공적으로 추진하는 데 필요한 요소들을 제시하고 인도네시아 선박안전관리체계에 대한 취약성을 분석하였다. 현재까지 인도네시아 선박안전 및 해양환경보호 역량강화에 관한 국제협력사업의 추진현황을 소개하고 현지 여건을 고려하여 국제협력사업을 성공적으로 추진하기 위한 방안을 모색하였다.
This study focuses on presenting a resistance capacity model of bridge which considers the surrounding environment. This model provides the timely decreasing characteristics of resistance capacity during the service life of bridge. The presented model is developed by using the statistical data announced to the public and the reliable research reports. The developed model is applied to evaluate the lifetime safety/reliability of a bridge. Based on the result of this evaluation, this study aims to accumulate the basic data of bridge maintenance works.
