Purpose: The aim of this study is to examine the effectiveness of an computer-tailored intervention program to promote breast-feeding. Method: A quasi-experimental design was used assigning forty pregnant women to the experimental group (computer-tailored intervention condition) and the control group (no-intervention control condition). Thirty-three participants completed pretest and posttest questionnaires and 19 participants assigned to intervention condition received personal feedback tailored by computer program. Result: Participants in the experimental group showed higher mean score of 'perception of the importance of breast-feeding'. Significant differences in internal health locus of control was found between the participants in the experimental group and the control group. Participants in the experimental group exceeded controls on intention of breast-feeding. Participants in the control group more often felt that the length of program contents they received was somehow longer. Conclusions: The use of a computer-tailored intervention improved the perception of the importance of breast-feeding and the internal health locus of control. The intention of breast-feeding was increased through the personal feedback tailored by computer even though participants felt that the length of program contents of tailored feedback was not longer.

Purpose: This study was conducted to assess the effects of robot-assisted gait training with visual feedback on gait, balance, and balance confidence in patients with chronic stroke. Methods: Thirty subjects with chronic stroke were randomly assigned to two groups: the experimental group (n=15) and the control group (n=15). The experimental group performed robot-assisted gait training for 30 minutes and the control group performed gait training with assisted devices training for 30 minutes after both groups performed conventional physical therapy for 30 minutes. Both groups performed the therapeutic interventions for 5 days per week, for a period of 4 weeks. For assessment of the 10 m walking test (10 MWT), Figure of 8 on the walk test (F8WT), Timed-Up and Go test (TUG), and Berg Balance Scale (BBS) were used to test the gait and balance, and the Korean version of the Activities-specific Balance Confidence Scale was used to test the balance confidence. Results: The experimental group showed significant improvement in the 10 MWT and the K-ABC (p<0.05), and the control group showed significant improvement in the BBS and the TUG (p<0.05). In four measurements, there were significant differences between the two groups (p<0.05), and the control group showed significant improvement in the F8WT at pre and post intervention (p<0.05). Conclusion: This study demonstrated that Robot-assisted gait training with visual feedback is an effective intervention for improving straight gait abilities and balance confidence, while the control group showed some improvement in curve gait and balance. Thus, we suggest both Robot-assisted gait training with visual feedback and gait training with assisted devices training exercise as a therapeutic intervention in chronic stroke rehabilitation.

교실수업에서는 지속적인 면대면 피드백을 통해 학습동기를 부여하고 학습 성취 욕구를 충족시켜주어 몰입학습을 유도 할 수 있으나 이러닝에서는 교실수업에 준하는 상호작용수준에 미치지 못하고 있어 많은 학습자들이 중도탈락이나 포기를 하고 있는 실정이다. 이러한 이러닝 환경에서의 문제점을 개선하고자 본 연구에서는 교실수업에서 사용하는 대화 피드백을 시스템에서 제공해 주어 학습자의 몰입학습을 증진시키는 대화 기반 피드백 시스템을 개발하였다. 개발된 시스템을 학교 현장에 적용해 보았으며, 그 결과 실험집단이 통제집단에 비해 학습자 개인에게 명확한 학습 목표의식과 도전감, 구체적인 피드백이 이루어져 몰입학습을 증진시킨 것으로 나타났다. 이는 본 시스템에서 제공해 주는 대화 기반 피드백이 학습자에게 적극적인 학습참여 자세를 배양하였고 학습의 흥미와 관심을 유지시켜 몰입학습을 유도하였음을 시사하고 있다. 끝으로 본 연구가 가지는 의의로 이러닝 환경에서 새로운 학습 시스템의 개발 방향을 제시하였다고 결론지을 수 있다.

Purpose : The purpose of this study was to compare the effects of performing feedback vs repeative tasks on lower extremity motor function and falls efficacy in chronic hemiplegic patients. Methods : 40 hemiplegic patients took part in this study. The average age of the feedback-task group was 68.45 years and 68.20 in the repeative-task group. All subjects participated in the study for 8 weeks, doing exercises 3 per day per week. All participants were assessed by using the Berg balance scale (BBS), the lower-extremity subscale of the Fugel-Meyer assessment of sensorimotor impairment (FMLE), and the falls efficacy scale (FES). The data were analyzed using a paired t-test. Results : After 8 weeks of exercise training, the results of this study were: the BBS and FMLE of hemiplegic patients showed a feedback-task and repeative-task groups (p<0.05). The FES of hemiplegic patients also showed a significant difference between the quantitative-task and qualitative-task groups (p<0.05). Conclusion : We present findings suggesting that chronic hemiplegic patients could improve their standing balance ability better through a feedback-task exercise program, as opposed to a repeative-task exercise program.

The authors investigated the effect of feedback and remediation after formative assessment (FRFA) by comparing the FRFA score and that of summative assessment (SA) in a course on clinical skills. In March 2015, 33 subjects underwent evaluation of their ability to perform a complex clinical skill using a real-time ready-made mobile assessment form tool, and through e-mail they were supplied with their feedback and final score (the pass group earned 2 points; the intermediate group earned 1 point; the nonpass group earned 0 points) followed by their self-reflection. The nonpass group underwent a re-test and e-mail feedback again until they passed the test, given the ease of performance. In December 2015, the 33 subjects took a 10-item SA, and one of the 10 items addressed a similar clinical skill. The difference between the first score on the FRFA and the score on the SA was evaluated statistically (p=0.05) through data analysis, variance distribution, correlation analysis, and linear regression analysis using SPSS software ver. 16. The increase from the score on the SA to that on the FRFA was statistically significant ($4.5{\pm}9.29$) in the pass group and the intermediate group, and was $29.7{\pm}11.49$ in the nonpass group of the formative evaluation (p<0.001). Using an FRFA could decrease the range in the standard deviation of the score and increase the minimum score among the subjects.

This study compared the effects of praise and punishment for improving safety behaviors. Participants were 30 volunteer undergraduate students and they were randomly assigned to one of two experimental conditions: (1) praise under which positive feedback was delivered for safe behaviors, (2) punishment under which negative feedback was delivered for unsafe behaviors. A simulated computerized work task was developed specifically for this study. Participants had to work on the work task and follow seven safety rules while working. When they follow all the seven safety rules, their behaviors were considered safe. If they did not follow any one of the rules, their behaviors were considered unsafe. Results showed that the percentage of safe behavior under group of praise feedback was significantly higher than under group of punish feedback.

Purpose: The purpose of this study was to investigate the effects of a visual feedbackbased balance training, using force platform biofeedback, on the postural balance of elderly faller. Methods: Fifty one community-dwelling older adults (aged 66-88 years) with a recent history of fall participated in the study. Participants were randomized to an experimental group (EG, n=25) and to a control group (CG, n=26). The EG participated in training sessions three times/week for 6 weeks. Visual feedbackbased balance training with the a computerized force platform with visual feedback screen was used in the experimental group. Static balance (center of gravity) and dynamic balance (Functional reach test, Timed "Up & Go" test, Berg balance scale) were assessed before and after end of training. Results: A significant improvement in static balance and dynamic balance were demonstrated within the EG (p<.05), but not in the CG. Conclusion: Visual feedback-based balance training may be an effective intervention to improve postural balance of elderly fallers.
