척추재활운동을 위한 디지털 압력바이오피드백 장치의 사용성 평가
김태호(T. H. Kim),오도봉(D. B. Oh),김다연(D. Y. Kim) 한국재활복지공학회 2017 재활복지공학회논문지 Vol.11 No.3
임상현장에서 압력 바이오피드백 장치는 요통 환자들의 척추재활운동에 사용되고 있으나, 여러 가지 단점을 갖고 있다. 본 연구는 사용자에게 신체의 움직임과 균형을 센싱하고 모니터링하여 사용자에게 바이오피드백을 제공함으로써 척추재활운동시 실시간으로 정확한 운동방법과 자세를 제공하는 디지털화된 압력 바이오피드백 장치를 개발하고자 하였다. 그 후 사용성 평가를 진행하여 안전성, 수행성, 조작성, 만족성 등의 문제점을 파악하고 개선방향을 제시하고자 한다. 본 연구에 참여한 대상자는 총 33명으로 전문가 평가 집단 11명, 사용자 평가 집단 22명으로 실제 개발된 장비를 사용 후 5점 척도로 평가하였다. 사용자 집단에서는 안전성 3.59점, 조작성 4.38점, 만족성 4.49점으로 나타났으며, 전문가 집단에서는 안전성 2.86점, 조작성 3.91점, 수행성 4.28점으로 나타났다. 본 사용성 평가를 바탕으로 태블릿PC 거치대의 안정성 문제, 공기주입, 화면 표시 등의 문제점을 개선한다면 척추안정화 운동을 하면서 실시간 자신의 운동상태를 확인하여 정확한 운동과 기능 평가가 가능한 운동장치가 될 것이다. In the clinical setting, the pressure bio-feedback device is used for the spinal rehabilitation of patients with back pain, but it has several disadvantages. The purpose of this study was to develop a digitalized pressure biofeedback system that provides precise exercise method and posture in real time during the spinal rehabilitation exercise by sensing and monitoring body movements and balance of users and providing biofeedback to users. After that, the usability testing for a digitalized pressure biofeedback system will be conducted to identify problems such as safety, performance, operability, and satisfaction, and suggest improvement directions. A total of 33 subjects were participated in the usability testing. The experts group and the users group evaluated the developed digitalized pressure biofeedback system on a scale of 5 points after using the equipment. In the user group, safety was 3.59, operability was 4.38, satisfaction was 4.49. In the expert group, safety was 2.86, operability was 3.91, and performance was 4.28. Based on the usability evaluation, if the problems of stability of the cradle for tablet PC, air injection, screen display, etc. are solved, it becomes a exercise device capable of accurately exercising and evaluating the function of the spine by checking its own motion state while the spinal stabilization exercise.

Purpose: The purpose of this study was to determine the sexual knowledge, and sex education perception and current status of the parents of preschoolers. The objective was to analyze the relationship between sexual knowledge and sex education demands of parents. Method: The method used in this study was a descriptive correlationstudy. The subjects were 278 parents of 3-to-6 year old children in 5 kindergartens located in Seoul. Data were analyzed using frequency, percentage, average, standard deviation, t-test, ANOVA, Scheffe test, and correlation using the SPSS 20.0 program. Result: The results of this study were the following: 1.There was no significantdifference in the sexual knowledge between the father and mother of preschoolers (Father 20.76, Mother 20.73). According to the findings, sexual knowledge was higher when both father and mother were older (P=.005). Similarly, when the economic level of the father and mother was high, sexual knowledge was also high (P=.030). 2.Concerning sexual education perception, it was found out that both father and mother thought that sex education was necessary. 3.In terms of sex education, a significant difference was noted. Mothers conducted sex education more often than fathers (Fathers, 46.7% Mother, 60.3%). Both the father and mother thought that providing sex education would be best in Grades 1-2, especially for ages 6-7. 4.When asked about the demands for sex education in terms of the physical, social, and living aspects, living aspect was the highest demand. It was revealed that both fathers and mothers were aware of the need for sex education, and when parents hadmore sexual knowledge, they would demand more sex education. Accordingly, there was a correlation between parent’s sexual knowledge and demand for sex education (r=.202, p=.001). Conclusion: Since the age,knowledge, education and economic levels of parents were different, it was necessary to develop sexeducation programs in accordance with their levels. In this way, preschooler parents would be able to teach sex education appropriate to their children’s level.
