In this paper, we propose a methodology for classfying types of lower limb disability and their mechanical structure, based on extensive survey of previous developments. We also propose a task-oriented design with human-friendly and energy-efficient assistive system. The result can be used for optimal design of wearable walking-assistive robot donsidering the type of disability and the content of task.

Wished to measure and analyzes blood pressure change of that walk forest walking path to woman among slight illness hypertensive who move into silver town and when walked asphalt walking path so that this study searches positive effect about that it so that may recognize widely positive side through that walk for blood pressure coercion of hypertensives exercise do and walks in forest exercise and clear benefit of forest walking path. Through this study, proved study finding is as following. 1) Exercise to walk estimates distance more than minimum 1200m that can see positive effect though do exercise. 2) According to result that blood pressure change of asphalt walking path and forest walking path does comparative analysis, significance probability was recognized at systolic blood pressure, and change of blood pressure was recognized significance probability at systolic blood pressure after exercise on the forest walking path. 3) Result that woman old man and slight illness high blood pressure old man woman blood pressure does comparative analysis, forest walking path after exercise in contraction period, relaxation period blood pressure significance probability recognize. These result estimates by thing which it can maximize effect of exercise that walk on the forest walking path that do exercise. 4)Appeared by thing which synonymy is between sequence, two circles that emotion state on forest walking path and asphalt walking path does comparative analysis, and change of emotion state was recognized significance probability in the most articles after forest walking path exercise. This can judge kinetic effect that keep emotion state that can maximize in case of do exercise on the forest walking path. This studies are giving effect that walk exercise is positive in old man woman's body, but examines closely that the floor was displaying effect that was surrounded by the tree than hard asphalt walking path and walks on forest walking path of soft earth road exercise is positive in body and confirmed necessity of forest walking path.

Today the pedestrian-related problems a key subject requiring the attention of the traffic engineers for improving the transportation system. Particularly in urban and CBD locations, the pedestrian presents an element of sharp conflict with vehicular traffic. Therefore pedestrian movements must be studied for the purpose of providing guideline for the design and operation of walking transportation systems. This paper is to address the characteristics of walking transportation in a big city. Especially the focuses are emphasized on the ratio occupied by pedestrian traffic among the whole unlinked trips in a city and walking time. The data for analysis are collected in Seoul metropolitan city through sampling 1,006 citizens. Compared with other similar research works this paper utilized diversified tools to acquire more useful results. Finally, policy directions for pedestrian environment improvement were suggested.
