Until now, the location and the size of gate are designed by only experience and intuitive use judgement. However there are no studies that investigated how many people will be using each subway gate depending on the location of gates. Therefore, the purpose of this study is to develop a gate choice model of subway station. The most critical element of a gate choice in subway station is the location of pedestrian's destinations. In this study, the development of the regression model is constructed from data of land use characteristic of station vicinity and the number of bus route and the space structure of station vicinity(Depth concept by Space Syntax analysis and total road length of station vicinity) by using the real data of 30 subway station in Seoul. This study found that subway pedestrian flow are mainly determined by three factors; the total floor space of commercial buildings, Total Depth(space structure index of station vicinity), and the number of bus route. The verification of a proposed model is done by using the real gate pedestrian data of two subway station in Seoul; Gang-nam and Yang-jae. The additional study of how to define the gate impact area is analysed. Therefore, this study will provide the theoretical bases in decision of gate location and size when a new subway station is opened in future.

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.

젖소를 사육하는 농가에서 가장 쉽게 발견되는 발굽관련 질병은 양축가에게 직접적인 경제적 손실을 야기함에도 불구하고 관심부족과 정기적인 발굽삭제 미실시 그리고 처치비용에 대한 부담 등으로 치료에 주저하는 경우가 많다. 발굽질병을 치료하지 않고 방치할 경우 단기적으로는 부자유스러운 걸음걸이와 보행시 느끼는 통증 때문에 이동거리를 제한하여 사료섭취량의 감소를 야기해 유생산량의 저하를 불러일으키고 치료시 비용에 대한 부담감을 갖게 하지만 장기적으로는 수태율 감

The purpose of this study was to evaluate the effects of proprioceptive exercise on walking velocity, activities of daily living(ADL) and depression in elderly women. This study was nonequivalent control group pre-post test design. Subjects were divided into two group(exercise group=17, control group=15). Experimental group conducted proprioceptive exercise program for eight-week. Walking velocity was assessed by 10m-walk test and depression and ADL were assessed by questionnaire. The collected data analyzed by Wilcoxon singed rank test and Mann-Whitney U test. The exercise group significantly improved walking velocity. But control group changes were negligible. The program was effective on walking in elderly women.

This work proposes a new method to generate velocity profile of a traction motor equipped in a rehabilitation system for knee joint patients through humanoid robot simulation. To this end, a three-dimensional full-body humanoid robot model is newly constructed, and natural human gait is simulated by applying to it reference joint angle trajectories already published. Linear velocity is derived from distance data calculated between the positions of a thigh band and its traction motor at every sampling instance, which is a novel idea of this paper. The projection rule is employed to kinematically describe the humanoid robot because of its high efficiency and accuracy, and measured joint trajectories are used in simulating human natural gait referring to Winter's book. The attained motor velocity profile for a certain position in human body will be applied to our walking-assistance system which is implemented with a treadmill system.

Nowadays, the number of people who do not move actively or are treated for rehabilitation is increasing because of the disorder or the paralysis of their own lower body by the industrial disaster. In this study, the walker for the people whose bodies are not convenient or the old is investigated. The walkers due to the height of walker are designed and the structural simulation analysis is carried out. The study models of walker are modelled with CATIA program and analyzed with ANSYS program. As the analysis result, the models of 1, 2 and 3 have the maximum stresses extremely below the yield stress of this model and the elastic deformations at these models occurs. Among these models, As the maximum deformation of model 3 has the least value among these models, models 3 is thought to have the best durability. The safety of walker model can be estimated by the basis of the result of this study. The damage can be prevented and the durability is examined by applying this result into the design of walker. And it is possible to be grafted onto the convergence technique at design and show the esthetic sense.

The pattern of traffic streams in residential streets is different from the ordinary roads separated by pedestrian and car lanes. Such fact makes it difficult to evaluate the new counter-measures with existing indices and methods. In this study, a unified, consistent new method is introduced as Time-Space Occupancy (TSO) concept. An application of TSO concept will suggest a TSO exposure volume index which can show the decree of danger in residential streets where vehicles, pedestrian and other traffic streams are interacted. The validity of TSO exposure volume index will be verified through the survey conducted in Seoul and the subjects will be the residents who live at various kinds of residential streets.

In this paper, we introduce a unit root test via discrete cosine transform in the AR(1) process. We first investigate the statistical properties of DCT coefficients under the stationary AR(1) process and the random walk process in order to verify the validity of the proposed method. A bootstrapping approach is proposed to induce the distribution of the test statistic under the unit root. We performed simulation studies for comparing the powers of the Dickey-Fuller test and the proposed test.

보행자 탐지를 위해 많은 알고리즘들이 제안되었고 그 중 HOG 알고리즘은 가장 좋은 성능을 보이는 알고리즘으로 알려져 있다. 하지만 HOG(Histogram of Oriented Gradients) 알고리즘은 연산량이 많아 계산 속도가 느려 실시간 시스템에 적용하기는 힘들다. 본 논문은 HOG 알고리즘으로 얻어진 특징 벡터를 이용해 보행자를 인식하는 방법의 속도 개선에 대하여 연구하였다. 기존 HOG 알고리즘에서 계산량이 많은 곳이 어느 부분인지 분석하고, 그 중 기울기와 방향을 계산하는 부분의 근사화를 통해 계산 속도를 높이는 방법을 제안한다.

It has reported that a median bus-stop island on an exclusive median bus lane (EMBL) has shortened a crossing distance unit, encouraged a pedestrian's illegal crossing, and increased the number of accidents in the area. This study presents (1) the analysis of inappropriate pedestrian crossing patterns collected on exclusive median bus corridors and (2) the estimated performance of safety barriers restraining the occurrence of those. Total 19,649 pedestrian crossing data collected at the 'Sookmyung-university' median bus-stop, and the inappropriate pedestrian crossing patterns among those were grouped in terms of time and space violations. Physical safety barriers restraining illegal pedestrian crossings were considered as an alternative, and its performance in safety was quantified through microscopic simulation with conflict analyses by using surrogate safety assessment model. The findings suggest the number of conflicts reduced be 24.9 percentages compared to the one of the present condition when the physical safety barriers are placed at each of the eight ends of the EMBL pedestrian crossing.
