  • 병원이나 검사실 등에 널리 이용되는 평형 기능 검사법은 고감도 압력센서를 이용한 균형감각조절임상검사(CTSIB, clinical test of sensory integration on balance)이다. 바로 선 자세에서 발바닥의 압력중심(center of pressure)의 변화를 관찰함으로써 흉부 흔들림을 객관적으로 측정한다. 본 논문에서는 가정에서도 손쉽게 흉부의 흔들림을 측정할 수 있는 방법을 제안하고자 한다. 위 밸런스보드(Wii balance board, WBB)는 게임기임에도 불구하고 흉부 흔들림과 상관관계가 높은 압력중심을 측정할 수 있기 때문에 기존의 임상용 제품과 유사한 결과를 보인다. 하지만 위 리모트 컨트롤러(Wii remote controller, WRC)는 WBB보다 저렴하고 손쉽게 구할 수 있음에도 불구하고 흉부 흔들림 분석에서는 압력 측정 방식이 아니기 때문에 기대만큼 활용되지 못하고 있다. 본 연구에서는 정상인 10명(남자:5명, 여자:5명)을 대상으로 WRC의 가속도 정보로부터 convex hull 혹은 ellipse area 분석법을 이용하여 WBB와 유사한 결과를 보였다.

  • What is attempted here is to find out an optimum method for the design of physical environments that could save human energy expenditures and safely perform household duties. There are, if any, very little amount of research done in this area. This is particulary so when the work relates to the designing of household storage facilities in the light of the energy metabolism of human body. The first step to this study, therefore, is to find out the ways by which we can determine the energy metabolism of human body accurately. To measure the volume and the concentration of human respiration continuously and automatically, a new apparatus is selected here. This includes the recording system with the Wright Respirometer and the Expired Gas Analyzer as well as the computer system to multiply volume by concentration of human respiration and to integrate them for a given time. Then, the author experimented on the reliability of this apparatus and came to the conclusion that this apparatus satisfied our need to research the energy metabolism of human body. Next, the general plan and procedures to experiment with this apparatus have been determined as follows: 1) subjects are three young and sound females. Their physical characteristics are shown in Table 1 and most approximates the standard characteristics of Japanese females, 2) height of open shelves is selected in such away as to correspond to the respective height of each subject(see Table 2), 3) utensils to be stored are box shaped object, which weight is 0.5kg, 1.0kg, 2.0kg or 3.0kg, 4) working motions are given while one or two hands as to place utensil on each shelf from the standard working board, 85 cm in height and then to place back it on the board from the shelf and repeated in constant velocity as 10 times per a minute, 5) each posture of motion is chosen by each subject in free, 6) procedures of measurement of human energy metabolism ard shown at(6), 1, Section 3 as specific methods for using this apparatus. Findings of this study are as follows: 1. Human energy expenditures for storing utensils on shelves by each subject are shown in quantity more accurately than in any other studies, under varying conditions about height of shelves, load of utensils and working motion with one hand and two hands (see Fig. 8~13 and Table 3). 2. Experimental formulae of human energy expenditure for that work are shown as formula (8), (9) and (10), to generalize results of 1. and to apply those for working motion under given conditions. 3. As results of analysis on gained data, we are able to show the standard model of human energy expenditures for storing untensils on shelves by the standard Japanese female (see Table 7 and Fig. 14).

  • 본 연구에서는 무구속, 무자각, 무침습적인 패치형 심장활동 모니터링 시스템(HAMS)을 개발하였다. 이 심전도 모듈은 무선 통신을 사용하여 신호를 컴퓨터로 전송 받아 실시간으로 피검자의 심장 활동 상태를 언제 어디서나 장시간 동안 손쉽게 모니터링 측정할 수 있는 이동성을 갖추고 있다. 가슴에 부착이 가능한 패치 타입의 소형 전극을 자체 제작하였고, 측정된 심전도 신호에 대한 신뢰성 검증이 이루어졌다. HRV에 대한 스트레스의 영향을 평가하기 위하여 HAMS을 이용하여 동일한 피험자를 대상으로 HRV 파라미터와 불안, 스트레스 항목에 대한 설문지 평가, 스트레스 호르몬(코티졸)양을 측정하였다. 일상 상태와 스트레스 상황에서의 값들을 비교한 결과, 많은 파라미터에서 유의미한 차이가 나타났다. 또한 피어슨 상관계수로부터 스트레스와 상관성이 높은 파라미터를 검토하였다. 이는 HAMS를 이용하여 자율신경계 기능 평가가 충분히 가능하다는 것을 보여주는 것이다. 이러한 결과로부터 HAMS를 통하여 일상생활에서 심장 이상을 예측할 수 있으며, 건강 모니터링 시스템으로 활용도가 높을 것으로 기대된다.

  • 재해로 인한 부상 및 만성 질환 등의 다양한 요인으로 신체적 장애를 가진 환자, 혹은 신체의 노화로 인하여 몸의 움직임의 범위가 제한된 노인과 같은 경우, 치료의 일종으로 병원에서의 재활 프로그램의 참여를 권장 받는 경우가 있다. 그러나 이들은 신체의 거동이 불편하므로 보호자의 동행 없이 재활 프로그램의 참여를 위한 이동이 쉽지 않다. 또한, 병원에서는 각각의 환자 및 노인들에게 재활 운동을 지도해주어야 하는 불편함이 존재한다. 이러한 이유로, 이 논문에서는 모션 인식을 통하여 집에서도 타인의 도움 없이 재활 운동이 가능한 원격 재활 프로그램을 개발하였다. 해당 시스템은 사용자 집의 스테레오 카메라와 컴퓨터를 이용하여 구동할 수 있으며, 모션 인식 기능을 통하여 사용자의 실시간 운동 상태 확인이 가능하다. 사용자가 재활 운동에 참여하는 동안, 시스템은 사용자의 특정 부위의 관절가동범위(Joint ROM; Joint Range of Motion)를 저장하여 신체 기능의 향상도를 확인한다. 이 논문에서는 시스템의 검증을 위하여 총 4명의 실험군이 참여하였으며, 총 3종류의 운동을 각 9회씩 반복한 데이터를 이용하여 각 실험군의 시작 및 마지막 운동의 관절가동범위의 차이를 비교하였다.

  • Korea has been recently reducing the quality of life as well as rising medical cost because of the increase of chronic diseases. But we can prevent those chronic diseases through the improvement of environment or life style. We evaluated the educational effectiveness of chronic diseases(hypertention, diabetes, cancer, stroke and other chronic diseases) designed to increase the knowledge, attitude and practice of chronic diseases among university students. Between August 1994 and November 1994, we implemented chronic diseases prevention instruction in intervention students; unmatched control students were selected in same university. We conducted pre- and post-intervention surveys both intervention and control students with self-reported questionnaires(50 items). We assigned score(0-4 points) to items and conducted a analysis of covariance(ANCOVA) with sex, grade and economic status as the covariate, using the SAS PC computer statistical package. And we culculated odds ratio with safety scores between intervention and control students. The results of this study were followed. 1. In demographic characteristics of subjects both pre- and post intervention, we found no significant differences in intervention and control students at religion, father's education, mother's education, mother's occupation and type of residence(p>0.05), but we found significant differences at sex(p<0.001), grade(p<0.001) and economic status(p<0.05). 2. The sex, grade and economic status-adjusted mean prevention knowledge scores for diabetes and stroke increased from the pre- to post-survey in the intervention students(p<0.001), but control students did not increased(p>0.05). As odds ratios in knowledge were below 1, the knowledge of intervention students were higher than control students. 3. The attitudes for general adult health increased from the pre- to post-survey in the intervention students(p<0.05), but control students did not increased(p>0.05). As odds ratios in attitudes were approximately 1, we can not say effectiveness in intervention students 4. The pratices for cancer and stroke increased from the pre- to post-survey in both the intervention and control students(p<0.001). Also odds ratio of hypertention was 0.91, and that of stroke was 1.14. 5. Health related behaviors did not increased from the pre- to post- survey in both the intervention and control students(p>0.05). But odds ratio of drinking was 0.76 and that of body weight was 1.21. 6. Health status did not increased from the pre- to post- survey in both the intervention and control students(p>0.05). As odds ratio of health status was 1.09, prevention education was not effect in intervention students We would like to recommend as follows; 1. University students must learn about prevention of chronic diseases. Because the knowledge of invetervention students was higher than that of control students. 2. The prevention education of chronic diseases should be taught from primary school. 3. Adult health education for university students must be practiced continuously. Education period(l5 weeks) in this study was not complete. 4. The evaluation of chronic diseases was conducted real measurement(such as BP check) as well as self reported-survey. 5. Educational materials(video tape, pamphlet) related the prevention of chronic diseases should be developed at national level. And we must easely use those materials. 6. The prevention education of chronic diseases should be made through mass media as well as school education.
