  • PURPOSE: The purpose of this study was to investigate effect of self-controlled feedback on proprioception in elbow flexion. METHODS: Thirty young adult volunteered to participate and were randomly assigned to one of three groups (self-controlled, yoked, control). Power and velocity in elbow flexion was measured by PRIMUS RS (BTE Tech., Hanover, U.S.A). Statistical analysis was used multivariate ANOVA to know effect of self-controlled feedback on proprioception in elbow flexion. Post hoc was used Scheffe. RESULTS: In acquisition phase to practice effect, variable errors in self-controlled group was significantly low scored more than yoked and control group. In retention phase to learning effect, variable errors in self-controlled group was significantly low scored more than yoked and control group. CONCLUSION: Self-controlled feedback was more effective on movement control when the learner could make a decision about receiving feedback after the trial. This seems to support the view that self-controlled feedback benefits learning, because learners can make a decision about feedback based on their performance on a given trial.

  • The purpose of this study was to examine the effects of self-controlled learning using the (KR) feedback schedule versus the yoked KR on the acquisition and retention of balance training for individuals with hemiplegics. Sixteen hemiplegics were randomly assigned to either a self-controlled or yoked KR group. All subjects were ambulatory with or without an assistive device. The self-controlled group was provided with feedback whenever they requested it, whereas the yoked group had no influence on the feedback schedule. All subjects performed 10 acquisition trials and 10 retention trials the day after acquisition. The data were analyzed using an independent t-test and a Mann-Whitney U test. Participants in the self-controlled group achieved significantly more effective learning than the yoked group during the acquisition and retention test except anterior/posterior (AP) body sway. These results suggest that a feedback schedule which is controlled by the individuals with hemiplegics may be more effective in balancing training than a yoked KR which is not controlled by the subject.

  • Purpose:The purpose of this study was to examine the effects of self-controlled knowledge of result (KR) versus the yoked KR on learning of knee joint proprioception. Methods:Forty volunteer subjects (20 men and 20 women) were randomly assigned to each four groups: 1) self-controlled KR in open kinematic chain, 2) yoked KR in open kinematic chain, 3) self controlled KR in close kinematic chain, and 4) yoked KR in close kinematic chain. The difference between the angle of position and reproduction angle was determined as a proprioception error and measured using an angle reproduction test. The subjects in self-controlled groups were provided with feedback whenever they requested it, whereas the subjects in yoked groups were not provided with feedback. The data were analyzed using a one-way ANOVA. Results:The proprioception errors in close kinematic chain groups decreased significantly compared with those in close kinematic chain groups(p<.05). The proprioception errors in the self-controlled group decreased significantly compared with those in yoked groups during acquisition and retention test(p<.05). Conclusion:Self-controlled knowledge of result during open kinematic chain movement is considered to be a good method on motor learning.

  • Purpose: This study was conducted to compare health-related characteristics and self-care behavior between a controlled group and a non-controlled group of hypertension patients in a customized home visiting health service. Methods: This study was conducted as cross-sectional research. The subjects were 1,317 hypertension-controlled patients and 555 non-controlled ones. Data were collected using a structured questionnaire and analyzed by descriptive statistics, $x^2$-test, and t-test using the SPSS WIN 15.0 program. Results: Sociodemographic characteristics and self-care behavior were not significantly correlated between the groups. According to health-related characteristics, the health status was significantly higher in the hypertensioncontrolled group than in the non-controlled group. The cholesterol level was significantly lower in the hypertension-controlled group than in the non-controlled group. Conclusion: Attention should be paid to patients who are not in good health status in order to control their hypertension. Also, it is necessary to educate the patients in order for them to manage their hypertension and cholesterol.

  • This study examined links between parental monitoring of child's daily activities, 3 sources of parents' knowledge, and children's deviant behaviors and self-esteem. Participants were 276 tenth grade boys. Children completed questionnaires about parental monitoring and their own internal adjustments and deviant behaviors. High parental control was linked to less deviant behavior in children regardless of children's feelings of being controlled. The association between parental control and children's feelings of being controlled was moderated by children's depression. Parental control was not related to children's depression and self-esteem, and further, children's feelings of being controlled were not related to self-esteem after controlling for depression. The findings suggest that parental control efforts are an effective way to prevent children's deviant behaviors.

  • The purpose of this research is to examine the empirical effect of participating motives for lifelong education on the releasing of controlled inferiority, the gratification of retained desire, and voluntary resocialization. The motives for lifelong education were divided into an external viewpoint focusing on consumers' behaviors and an internal viewpoint based on activity of the ego. External motives were divided into pragmatic, entertaining, and relational motives, while internal motives were divided into self-realization, self-existence, and self-participation motives. The results show that the pragmatic motive and the self-realization motive, the entertaining motive and the self-existence motive, and the relational motive and the self-participation motive are highly related to each other. It was found that the pragmatic motive and the self-realization motive affected the lifelong education participants' release of controlled inferiority relatively stronger, the entertaining motive and the self-existence motive affected participants' gratification of retained desire relatively stronger, the relational motive and the self-participation motive affected participants' voluntary resocialization relatively stronger.

  • The present work proposes a self-controlled multi-stage optimization method for damage identification of structures utilizing standard particle swarm optimization (PSO) algorithm. Damage identification problem is formulated as an inverse optimization problem where damage severity in each element of the structure is considered as optimization variables. An efficient objective function is formed using the first few frequencies and mode shapes of the structure. This objective function is minimized by a self-controlled multi-stage strategy to identify and quantify the damage extent of the structural members. In the first stage, standard PSO is utilized to get an initial solution to the problem. Subsequently, the algorithm identifies the most damage-prone elements of the structure using an adaptable threshold value of damage severity. These identified elements are included in the search space of the standard PSO at the next stage. Thus, the algorithm reduces the dimension of the search space and subsequently increases the accuracy of damage prediction with a considerable reduction in computational cost. The efficiency of the proposed method is investigated and compared with available results through three numerical examples considering both with and without noise. The obtained results demonstrate the accuracy of the present method can accurately estimate the location and severity of multi-damage cases in the structural systems with less computational cost.

  • This paper presents the self-commissioning for surface-mounted permanent magnet synchronous motor. The proposed strategy executes three tests with a vector controlled inverter drive system. To do this, synchronous d-q axes currents are appropriately controlled for each test. From the three tests, armature resistance, armature inductance, equivalent iron loss resistance, and emf coefficient are identified automatically. The validity of the proposed strategy is confirmed by experimental results.
