Background: Stroke patients have leg muscle weakness and impaired balance resulting in compensatory changes. To restore balance in these patients, functional training using postural strategy is needed. Objective: To examine the effects of ankle and hip strategy training on the center of pressure (COP) movement and limits of stability (LOS) in standing posture in stroke patients. Design: The study was an assessor-blinded and randomized-controlled clinical trial. Methods: Thirty patients were randomly assigned to an ankle strategy training group and a ankle/ hip strategy training group. Patients in the ankle strategy training group underwent ankle strategy exercise for 30 min, and those in the ankle/ hip strategy training group underwent 15 min of ankle strategy exercise and 15 min of hip strategy exercise. Both groups underwent training thrice a week for four weeks. Forward, backward, paretic side, and non-paretic side COP movements and LOS were measured using BioRescue. Results: After the intervention, except for the backward area in the ankle strategy training group, the COP movement area and the LOS were significantly improved in both the groups. In addition, these improvements were significantly higher in ankle/ hip strategy training group than that in the ankle strategy training group. Conclusions: Ankle strategy training in addition to hip strategy training improves COP movement (forward-backward, paretic side area, and non-paretic side area) and LOS in stroke patients.

The present research studied the effectiveness of specific strategy training in memory awareness on children's memory performance. The subjects were 60 children, 30 six-year-olds and 30 eight-year-olds. Free recall scores and use of a rehearsal strategy (exposure durations) based on Belmont & Butterfield (1971) were used to measure children's performance in three memory tasks. All subjects were randomly assigned to one of three experimental groups: the control group with no training, the chunking and rehearsal strategy training group, and the chunking and rehearsal strategy training combined with memory awareness strategy. The data were analyzed with two-way ANOVA, three-way ANOVA with repeated measures, and Student-Newman-Keuls post hoc test. There were significant differences among the three groups both in the free recall score and in the use of the rehearsal strategy. The mnemonic strategic training with memory awareness strategy was the most effective on both free recall and use of rehearsal strategy. The effects of the mnemonic strategy training with memory awareness strategy were more effective for the 8-year-olds than the 6-year-olds.

This paper proposes training algorithms of neuro-fuzzy systems. First, we introduce a structure training algorithm, which produces the necessary number of hidden nodes from training data. From this algorithm, initial fuzzy rules are also obtained. Second, the parameter training algorithm using evolution strategy is introduced. In order to show their usefulness, we apply our neuro-fuzzy system to a nonlinear system identification problem. It was found from experiments that proposed training algorithms works well.

This research defined professionality of science teacher from the perspective of PCK. An teaching strategy in the in-service teacher training for the gifted education was proposed based on the definition and implemented at an in-service teacher training program for the gifted education in order to explore about the teaching strategy and suggest practical implications that could improve the program. The in-service teacher training teaching strategy proposed in this research consists of three components: 'crafting activity materials', 'conducting inquiry-based experiment', 'developing rubric for identification of giftedness'. The survey carried out for the participants of the teacher training program showed that teachers perceived the importance of the need for the rubric for gifted identification, developing activity materials for the gifted education in science, and developing the rubric of gifted identification as properties for in-service teacher training programs fur the gifted education. However, the insufficiency of time and opportunities for being fully engaged in such a program made teachers feel lack of self-confidence in developing activity materials for the gifted education in science and rubric for gifted identification. Therefore, teacher training programs reflecting real features of the gifted education should be constantly developed and provided to enhance the effectiveness of in-service teacher training programs.

Purpose: The purpose of this study was to investigate the effect of balance using ankle strategy during adjusted balance training and muscle training in normal young female adults. Methods: There were eighteen participants. All subjects were randomly assigned to three groups, the control group (n=6), the adjusted balance training group (n=6) and the muscle training group (n=6). Subjects were assessed for each subject by a pretest and a posttest at 1 week, 2 weeks, and 3 weeks, measuring the anterior-posterior limit of stability, trace length and EMG data for the tibialis anterior and lateral gastrocnemius. Results: The anterior-posterior limit of stability significantly increased in the training group (p<0.05). The trace length significantly decreased in the training group (p<0.05). The muscle activity of the tibialis anterior and lateral gastrocnemius also significantly decreased in the training group (p<0.05). Conclusion: We confirmed that both the balance training group and the muscle training group significantly increased the anterior-posterior limit of stability and decreased trace length and muscle activity. Further studies are needed to analyze the long-term effects on subjects resulting from these changes.

본 연구는 노인여성들을 대상으로 발목관절 전략 집중 훈련이 근력과 균형능력에 어떠한 영향을 미치는지를 알아보고자 하였다. 연구대상자는 65-80세 사이의 여성노인 30명으로 선정하였다. 대조군(n=10)은 아무런 처치를 하지 않았고, 실험군 I(n=10)은 일반적 하지의 운동만 실시하였다. 실험군 II(n=10)는 세라밴드를 이용한 근력운동과 air cushion, unstable board을 이용한 평형운동을 포함한 발목관절 전략 집중 훈련을 실시하였다. 두 실험군은 6주간 주 3회 1시간 훈련을 실시하였다. 6주간 일반적 하지 운동과 발목관절 전략 집중 훈련을 각각 실시한 후 dynamometer, FRT, SEBT를 측정한 결과 대조군과 실험군 I의 변화는 통계학적으로 유의하지 않았지만, 실험군 II의 변화는 유의하게 증가하였다(p<.05). 더불어 노인 낙상 예방 및 치료적 접근에 있어서 발목관절 전략 집중 훈련을 통한 다양한 변인의 추가적인 연구가 필요하다고 생각된다.

Generally, the training set of maximum $m{\times}L(m+f)$ patterns in the pattern recognition method is required for the real-time bus reconfiguration strategy when a main transformer fault occurs in the distribution substation. Accordingly, to make the application of pattern recognition method possible, the size of the training set must be reduced as efficient level. This Paper proposes a methodology which obtains the minimized training set by applying the pattern clustering method to load patterns of the main transformers and feeders during selected period and to obtain bus reconfiguration strategy based on it. The MaxMin distance clustering algorithm is adopted as the pattern clustering method. The proposed method reduces greatly the number of load patterns to be trained and obtain the satisfactory pattern matching success rate because that it generates the typical pattern clusters by appling the pattern clustering method to load patterns of the main transformers and feeders during selected period. The proposed strategy is designed and implemented in Visual C++ MFC. Finally, availability and accuracy of the proposed methodology and the design is verified from diversity simulation reviews for typical distribution substation.
