  • The purpose of this study was to investigate gait factor and muscle activity depending on hiking poles-using. Eight healthy men volunteered for this experiment. Each of them performed down-hill walking with hiking poles-using and without poles at speed of 3.5km/h for 45 minutes on a treadmill. The treadmill was set 25% down-hill inclination. Kinematic data collected in 60Hz were recorded and analyzed by using 2D motion capture system to measure step time and step length so on. And the lower extremity muscle activities were simultaneously recorded in 1500Hz and assessed by using EMG. The statistical analysis was the paired t-test with repeated measures to compare between hiking poles-using and without poles. The level of statistical significance for all tests was .05. The results of this study were following : Step time was showed statistically different according to pole conditions. That is, the case of poles-using was longer than without poles in step time. Also, step length was showed statistically different between two conditions. Step length about trials with poles was longer than trials without poles. In the muscle activity, the case of all muscles was not showed statistical significance about pole conditions. However, in most muscles IEMG, there were some decreasing-trend relatively when hiking polesusing.

  • The purpose of the present study was to investigate the effects of familiar exercise and novel exercise on motor function after intracerebral hemorrhage (ICH) in rats. The rats were subjected to a unilateral striatal ICH via collagenase infusion. The rats were randomly divided into the following three groups: the CON (control group; rested one week post-ICH), the FE (familiar exercise group; familiar exercise was performed two weeks after one-week post-ICH period), and NE (novel exercise group; novel exercise was performed two weeks after one-week post-ICH period). We measured neurological behavior using a ladder rung walking test and a beam walking test; we measured the level of nerve growth factor (NGF) using immunohistochemistry and western blot analysis. We performed a one-way ANOVA test to analyze the scores obtained from the neurological behavior tests and the differences of NGF protein levels among the three groups. In the present study, the FE group and the NE group showed significant improvement during the neurological behavior tests and in their expression of NGF protein level, as compared to the CON group. Especially, NE group more increase than FE group in neurological behavior tests, the expression of NGF on motor cortex. In conclusion, these results suggest that, after ICH, familiar exercise and novel exercise enhance motor function and, novel exercise is more effective than familiar exercise.

  • The purpose of this study is to provide a practical guide for the actual conditions and the preference of student housing in a regional university. The data are collected through questionnaire surveys from the students of a regional university. 265 samples are collected, and are analyzed by using SPSS-PC. The results are as follows: 1) The actual conditions of student housing Most residents of student housing(76.3%) come from the Capital region. Most of student housing are located at 30 minute distance from the school. Most of house style are Offistel as one room style. Most of housing size are within 10 minute distance from the school. Most of house style are Offistel as one room style. Most of housing size are within 10py, and two people reside in one unit. The average hours of staying at the student housing are over 10 hours. The most inconvenient factor is the lack of soundproofing in the current student housing. 2) The preference of student housing The most preferred location is in the walking distance from the school, and the apartment is the most preferred housing style. The most preferred installation of inside is internet connection. When choosing student housing, students prefer the distance from the school as the most important factor. Most female students reside with a roommate within 10 py of housing size, cook for themselves, and consider rent and maintenance fee as the decision factors in choosing housing. The most preferred style of house is apartment, and they prefer to install basic furniture and kitchen system inside of housing. As students go up to higher grade, they prefer the apartment, and prefer to cook for themselves. More fresh men reside with a roommate compared to other grades. They prefer Offistel with meals service at a walking distance from the school.

  • 도시생활의 거점이며, 생활의 활력과 다양성을 제공하는 도시의 상업가로의 생동감은 도시 전체의 활기 및 지역 경제 활성화에 큰 영향을 미친다. 상업가로가 활성화 되었다는 것은 보행 활성화와 관계가 있는데, 보행이라는 것은 단순한 이동 행위를 넘어 주변 환경과 폭넓은 상호작용을 하기에 생활의 질과 밀접한 관계가 있다. 이 생활의 질은 '리버빌리티(살기 좋음)'로 이어진다. 상업가로의 보행활성화를 위하여 리버빌리티 요소를 도출하고 상업가로 활성화에 있어 가장 중요하고 효과적인 것이 무엇일지 우선순위를 분석하였다. 그 결과 장소성의 세부 지표인 그 자체의 분위기, 목적성을 나타내는 항목이 우선순위가 높게 나왔고, 접근성에 속한 세부 지표가 후순위로 나옴을 알 수 있었다. 상업가로의 리버빌리티를 높이기 위해서는 그 공간의 장소성을 높이는 것을 우선으로 하고, 이로 인해 방문객의 방문 횟수와 머무르는 시간 등이 늘어남에 따라 보행이 활성화 된다면 지역 전체의 활력으로까지 확장될 수 있다.

  • For the requirement of accurate tracking control and the safety of physical human-robot interaction, torque control is basically desirable for humanoid robots. Because of the complexity of humanoid robot dynamics, the TDC (time-delay control) is practical because it does not require a dynamic model. However, there occurs a considerable error due to discontinuous non-linearities. To solve this problem, the TDC-FLC (fuzzy logic compensator) is applied to humanoid robots. The applied controller contains three factors: a TDE (time-delay estimation) factor, a desired error dynamic factor, and FLC to suppress the TDE error. The TDC-FLC is easy to execute because it does not require complicated humanoid dynamic calculations and the heuristic fuzzy control rules are intuitive. TDC-FLC is implemented on the whole body of a humanoid, not on biped legs even though it is performed by a virtual humanoid robot. The simulation results show the validity of the TDC-FLC for humanoid robots.

  • 말초신경은 외상이나 질병 등 여러 가지 원인으로 손상되기 쉬우며, 손상의 정도가 심하거나 치료가 지연되는 경우에는 심각한 기능 소실을 초래할 수 있다. 본 연구에서는 수영이 말초신경손상후 운동기능의 회복과 뇌유인성 신경영양인자 (brain-derived neurotrophic factor, BDNF) mRNA의 발현에 미치는 효과를 알아보기 위하여, 흰쥐 좌골신경에 압박 손상을 가하고 수영을 적용한 후 보행궤적분석 (walking track analysis)과 역전사연쇄반응 (reverse transcription-polymerase chain reaction, RT-PCR)을 실시하였다. 그 결과, 좌골신경 압박손상된 쥐는 특징적인 보행패턴을 나타내어 좌골신경기능지수 (sciatic function index, SFI)가 현저히 낮아졌으며, BDNF mRNA의 발현이 증가하였다. 좌골신경 압박 손상후 수영을 한 쥐에서는 SFI가 현저히 향상되었으며, BDNF mRNA의 발현은 억제되었다. 이러한 결과는 말초신경손상후 수영이 BDNF mRNA의 발현을 조절함으로써 기능 회복을 촉진시키는 효과적인 치료방법이 될 수 있음을 제안하고 있다.

  • Smoke is one of the most critical factor when escaping from the fire since it reduces visibility and interrupts finding emergency exit lights. Therefore, it is recommended that an evacuation simulation program should incorporate the smoke factor. In addition, it is suggested that the program should include not only the unilateral damage by the smoke but also the detour evacuation by risk communication. In this study, MAS (Multi Agent System)-based simulation program which incorporates the reduced walking speed by smoke and adopts the dispersion evacuation logic during escaping from the fire. To make comparison, a commercial evacuation program, Pathfinder was used. It was found that the simulation results of MAS (Multi Agent System)-based program is better than Pathfinder in terms of safe evacuation. It means that evacuation simulation need a additional evaluation categories that include not only quick evacuation time but also safe evacuee number.
