리듬청각자극을 이용한 후방 보행 훈련이 뇌졸중 환자의 보행과 균형에 미치는 영향
현동수(Hyun, Dong-Su),최종덕(Choi, Jong-Duk) 한국산학기술학회 2013 한국산학기술학회논문지 Vol.14 No.12
본 연구는 리듬청각자극을 이용한 후방 보행 훈련이 뇌졸중 환자의 보행과 균형에 미치는 영향을 알아보기 위한 것으로 21명의 뇌졸중 환자를 무작위로 세 집단으로 나누었고, 실험군Ⅰ은 전방 보행 훈련 군, 실험군Ⅱ은 후방 보행 훈련군, 실험군Ⅲ은 리듬청각자극을 이용한 후방 보행 훈련 군으로 집단마다 7명씩 실험하였다. 실험은 3주간 주 5회 30분씩 실시하였으며 실험 전과 3주간의 실험 후에 각 실험군의 10m 보행 검사, 일어나 걸어가기 검사, 기능 적 팔 뻗기 검사를 하였고, biodex gait trainer 2를 사용하여 활보장과 보장비대칭 비를 측정하였다. 연구의 결과 각 군내의 실험 전?후 비교에서 보행속도, 보행대칭성, 균형에 유의한 차이를 보였고(p<.05), 변화량을 비교했을 때 모두 유의한 차이를 보였으며,(p<.05), 보행속도, 보행대칭성과 균형에서는 실험군Ⅲ, 실험군Ⅱ, 실험군Ⅰ 순으로 효과적이였 고, 활보장에서는 실험군Ⅱ와 실험군Ⅲ이 실험군Ⅰ보다 효과적이였다. 이 결과를 통하여 뇌졸중 환자를 대상으로 보 행 운동을 실시할 때 리듬청각자극을 이용한 후방 보행 훈련이 보행속도, 보행대칭성과 균형의 향상에 있어서 효과적 인 방법임을 알 수 있다. This study examined the effects of backward walking with rhythmic auditory stimulation on the gait and balance of stroke patients. Twenty-one people were divided randomly into three groups; group Ⅰ(n=7, forward walking), group Ⅱ(n=7, backward walking), group Ⅲ(n=7, backward walking by rhythmic auditory stimulation). Each group was trained for 30 minutes 5 times per week for 3 weeks, and was evaluated using a 10m walking test, time up and go test, functional reach test, stride length and step length asymmetry ratio. As a result, the pre- to post-test measures revealed a significant effect in each group on the gait speed, gait symmetry and balance(p<.05). The walking speed, gait symmetry and balance were higher in group Ⅱ (p<.05) than in groupⅠ and it was the highest in group Ⅲ(p<.05). The stride length was higher in group Ⅱ and group Ⅲ(p<.05) than in group Ⅰ. In conclusion, for stroke patients, backward walking training with rhythmic auditory stimulation is effective on the gait speed, gait symmetry and balance.

In the event of fire in a compartment the available safe egress time for occupants to evacuate the compartment depends on the time of fire detection and on the time of onset of hazardous conditions. To know fire frowth and smoke transport for compartmented structure, actual fire tests of trasfcan, carpet, mattress and wardrobe were performed. The results are that the most hazardous gas is carbon monoxide(CO), carbon dioxide(CO_2), oxygen depletion hot temperature, etc, that the hot smoke temperature is almost same from 150cm to 290cm elevation off floor in the comportment, that the flashover was occurred in mattress and wardrobe fire.

Purpose : The purpose of this study was to find effects of early oral water intake on thirsty feeling, nausea, and vomiting after ambulatory surgery. Method : Sixty patients who received PET(Pressure Equalizing Tube) insertion surgery under general anesthesia were conveniently sampled and divided into two groups. Experimental group was instructed to drink water after two hours and control group was directed to intake water after three hours postoperatively. Data were collected from May 1, 2002 to August 31, 2002 at ambulatory surgery center of Asan Medical Center. The thirsty feeling, nausea and vomiting score between experimental and control group were compared at the time of recovery, recovering consciousness, 2hr, 3hr, right before discharge and/or 24hr(telephone interview) postoperatively. The collected data were analyzed by SPSS 8.0 statistic program. Result : Result of this study are as follows. 1) There was a statistically significant difference(t=-10.31, p=0.00) in the occurrence of thirsty feeling at the 3hr postoperatively between experimental and control groups. 2) There was a statistically significant difference(χ²=6.66, p=0.02) in the incidence of nausea during the 2hr postoperatively between experimental and control groups. 3) There was no difference(χ²=0.35, p=0.55) between groups in vomiting scores. Conclusion : It was generally known that the delay of oral water intake decreases post operative complications. But, this study shows that early oral water intake decreases discomfort of thirsty and there was no adverse effects on the occurence of postopeative nausea and vomiting.

The major difference between multi heat pumps and conventional heat pumps is the number of indoor units. For multi heat pumps, it is essential to have precise control of cooling capacity distribution to each indoor unit having different cooling load. Through the experiments with various test conditions, it was found that an indoor unit affected another by refrigerant mass flow rates, evaporating pressures and cooling capacities when temperature differences of inlet air between two indoor units were exist.
