The purpose of this study was to investigate the effect of cooperative skill training on elementary school students' science achievement and self-esteem. Three different groups were used in this study. For the two treatment groups, cooperative loaming strategies were used and the one control group, traditional instruction was used. One of the treatment group was trained cooperative skills before the instruction. A total of 120 children sampled from 5th graders of a elementary school. All groups were taught about the change of the weather and structure of the plants. After the instruction a researcher made science achievement test and questionnaire of self-esteem were administered. The data analysis consisted of a 3(instructional strategies)×3(learning ability level) ANCOVA on the score of the achievement and self-esteem. The ANCOVA results revealed that there were significant main effect in the scores of achievement and also significant interaction effect between the instructional strategies and learning ability. The performance of high-level students in two treatment groups was higher than that of students in the control group, but the performance of high-level students with cooperative skill training was not higher than that of students without cooperative skill training. However, the performance of medium and low-level students with cooperative skill training was higher than that of students without cooperative skill training. The significant main effect was also found in the self-esteem but there were no significant interactions between the instructional strategies and learning ability. The academic self and social self of students with cooperative skill training was higher than that of students without cooperative skill training.

Purpose: This study aimed to investigate the effect of progressive speed increase during underwater gait training on stroke patients' balance, gait, and endurance, as well as to compare the effects of underwater gait training and land gait training. Methods: Subjects were randomly allocated into three groups. Underwater gait training group (n=10), land gait training group (n=9) and control group (n=9). The groups performed their respective programs as well as conventional physical therapy 3 times/week for 8 weeks. The patients were assessed before and after the experiment in terms of the Berg balance scale, characteristics of gait, and 6-minute walking test. Results: The beneficial effect perceived in the speed increase underwater gait training (UGT) group was significantly greater than in the groups who were trained with speed increase land gait training (LGT) group, and the control group regarding the following aspects: the Berg balance scale, the affected step length, the affected stride length, and the 6-minute walking test (p<0.05). The LGT group showed a more significant effect on the Berg balance scale, the affected step length, the affected stride length, and the 6-minute walking test (p<0.05), compared to the control group. Furthermore, the UGT group showed a significantly greater effect on the gait speed when compared to the control groupb (p<0.05). Conclusion: This study shows that progressive UGT is effective in improving balance, gait, and endurance in stroke patients. Therefore, we believe that progressive UGT may be used as a method for general physical therapy in patients with stroke.

Objective: Stroke patients need the training to adjust their posture and maintain balance is necessary to restore movement function, and unstable support training is one of the appropriate training. In this study, a systematic review and meta-analysis were conducted to find out the effects of unstable surface training on balance and gait in stroke patients. Design: Systematic review and meta-analysis Methods: After creating a search expression referring to MeSH and EMTREE, the literature from 1976 to February 2022 was searched in the databases of PubMed, EMBASE, and Cochrane Library CENTRAL. A total of 331 studies were searched from three databases, and 11 studies were finally selected according to the inclusion criteria. Unstable surface training included studies using balance trainer, Whole-body vibration, and sand surfaces. Results: The results were found to be d=2.28 (p=0.02) and the effect size was 0.36 (95% CI: 0.05, 0.67) on the Berg Balance Scale. In the Kinesthetic Ability Trainer static balance, d=2.59 (p=0.01) and the effect size was 1.01 (95% CI: 0.24, 1.78). Timed Up and Go test showed that d=2.18 (p=0.03) and the effect size was 0.38 (95% CI: 0.04, 0.72). At the gait speed, d=0.99 (p=0.32) and the effect size was 0.15 (95% CI: -0.15, 0.45). In the 6-minute walk test, d=0.14 (p=0.89) and the effect size was 0.04 (95% CI: -0.47, 0.55). Conclusions: In this study was found that training was effective in balance if it became unstable in standing posture. Therefore, unstable surface training can be used to improve the balance of stroke patients in clinical practice.

In this study, adaptation of two-way shape memory effect of SMA wire to the actuator is examined. Therefore the SMA characteristics which are training, material properties, response time at different thermal cycling rates are tested. During training, permanent deformation is accumulated till a certain number of cycle and then saturated. The amount of two-way strain is unchangeable over all cycle and the slope of strain(or stress)-temperature curve is slower as the increase of applied stress. The rate effect is observed resulted from the thermal distribution which heating profile differs from cooling as thermal cycling time. Using the estimated SMA properties, an experimental test for the simple smart wing is performed.

Purpose : This study was performed to examine the effect of stimulation task-oriented training on the balance ability of the hemiplegic patients caused by stroke. Methods : We made a random sampling of 25 hemiplegic patients caused by stroke. 10 patients(experimental group)were treated by simulation Task-oriented training and Conventional training used by balance pad. The other 10 patients(control group) were only treated by Conventional training used by balance pad. During the training, 3 patients from the experimental group and 2 patients from the control group were excluded by private affairs. The control group has done Conventional training 6 times a week for 6 weeks. And experimental group has done Simulation task-oriented training two times, conventional training four times a week for 6 weeks. Balance ability was assessed by Fuctional Reaching Test (FRT) : unilateral and bilateral reaching. Results : In comparison of FRT before and after training, two groups all was significantly improved(p<.05). But bilateral reaching variation was significantly improved in experimental group. Conclusion : we can use simulation Task-oriented training valuably to increase balance ability of hemiplegic patients.

Objective: The aim of this study was to examine the effect of strength training targeting medial quadriceps/hamstrings and non-targeting strength training on dynamic balance. Method: A total of 51 healthy subjects were randomly assigned to control, targeting strength training, or non-targeting training groups. To measure the dynamic balance, the star excursion balance test (SEBT) was performed before and after training. The SEBT parameters were compared using repeated measures ANOVA, and post-hoc paired t test at a significance level of 0.05. Results: Greater anterior (p= .011), anteromedial (p= .001), medial (p< .001), lateral (p< .001), and anterolateral (p= .001) reach distances were found between pre- and post-training in the strength training targeting medial thigh muscles group. Only greater lateral reach distance was found after non-targeting strength training (p= .029). In addition, no differences were found for any SEBT scores in the control group. Conclusion: Strength training targeting medial quadriceps and hamstrings can improve the dynamic balance, thereby it positively affected in lower extremity injury risk, whereas non-targeting strength training rarely changes the dynamic balance.
