Purpose: The purpose of this study was to examine the effects of resistant gait training with proprioceptive neuromuscular facilitation (PNF) on the walking and balancing abilities of chronic stroke patients. Methods: Twelve chronic stroke patients were randomly assigned to either a control group (n = 6) that underwent treadmill gait training or an experimental group (n = 6) that underwent resistant gait training using PNF. The interventions were performed five times per week for four weeks. Gait variables were measured using a GAITRite system (CIR System Inc, Clifton, NJ, USA) to examine changes in walking ability; the Berg balance scale (BBS) was used to measure changes in balance; and the activity-specific balance confidence scale (ABC) was measured to examine changes in confidence about balance. A Wilcoxon signed-rank test was used to examine intragroup differences before and after the interventions, and a Mann-Whitney U-test was used for intergroup comparisons of the effects of the interventions. All statistical significance levels were set to ${\alpha}=0.05$. Results: Both the experimental group and the control group showed significant intragroup improvement in walking speed, the number of steps per minute, stride length, double support time, balance, and confidence about balance after the interventions (p < 0.05). In intergroup comparisons after the interventions, the experimental group showed significant improvements over the control group in walking speed, the number of steps per minute, stride length, balance, and confidence about balance (p < 0.05). No significant difference in double support time was seen in the intergroup comparison after training (p > 0.05). Conclusion: This study applied resistant gait training using PNF to chronic stroke patients, and the results showed significant improvements in the patients' walking and balancing abilities. Therefore, resistant gait training using PNF is thought to be applicable as an intervention method for chronic stroke patients.

Top Managers are apt to do the decision making on the base of cost-benefit analysis. Therefore the return on quality is indispensable to get the commitment of the top managers on the quality programs. The monetary or tangible effects of the most improvement activities through the suggestion systems and the quality circle activities are computed and reported. In most cases the reported gains are much bigger than the input invested. In spite of the reported high return many top managers are doubtful about the truth of reports because the gains are not translated into the profit on the income statement. This paper discusses about the mechanism of individual improvement activities and analyze the system effect which sum the individual effect and the realization effect on the income statement during that period. This will help the top managers to commit on the quality programs with high confidence.

Conventional post-processing as like confidence measure (CM) proposed by Rahim calculates phones' CM using the likelihood between phoneme model and anti-model, and then word's CM is obtained by averaging phone-level CMs[1]. In conventional method, CMs of some specific keywords are tory low and they are usually rejected. The reason is that statistics of phone-level CMs are not consistent. In other words, phone-level CMs have different probability density functions (pdf) for each phone, especially sri-phone. To overcome this problem, in this paper, we propose normalized confidence measure. Our approach is to transform CM pdf of each tri-phone to the same pdf under the assumption that CM pdfs are Gaussian. For evaluating our method we use common keyword spotting system. In that system context-dependent HMM models are used for modeling keyword utterance and contort-independent HMM models are applied to non-keyword utterance. The experiment results show that the proposed NCM reduced FAR (false alarm rate) from 0.44 to 0.33 FA/KW/HR (false alarm/keyword/hour) when MDR is about 8%. It achieves 25% improvement of FAR.

The purpose of this research is to study the influence over confidence and Word-Of-Mouth (WOM) effect in the acceptance process of WOM by information characteristics(consensus, vividness, and message neutrality) of individual cosmetic blog, reflecting that it is widely spreading over the public. Online survey for the consumers using such blogs was performed to collect data(N=200), and credibility analysis through Cronbach-${\alpha}$ and Structural Equation Model(SEM) analysis using AMOS 18.0 were performed. The analysis results are as follows; First, vivid information and neutral message increase WOM effect through the improvement of consumers' credibility whereas information consensus doesn't positively influence over credibility. Second, the examination of a moderating effect by type of cosmetics demonstrated that the consumers of basic cosmetics have most confidence in vivid information, and those of color cosmetics do more confidence in neutral message. Therefore, there is a difference in the credibility factor of online WOM depending on the type of cosmetics consumption so that differentiated information provision strategies for cosmetics groups should be established based on it.

Accident dangerousness of domestic hydro power generators which are operated in Korea is on the increase because of use at the long term. On this, the Off-line diagnosis techniques developed to the On-line by continued domestic technical development since 2000. Especially, On-line insulation diagnosis of domestic hydro power generator is possible by localization of partial electric discharge sensor and On-line insulation diagnosis system. This paper shows the diagnosis result that is applied localized Ceramic Coupler and PDMS-HG(Partial Discharge Monitoring System for Hydro Generator) at four Chung-ju hydro Generator used for 25 years. Particularly, the confidence of insulation diagnosis is improved by using high frequency filter and sampling the partial discharge signals which occur in site. For reviewing the confidence of On-Line insulation diagnosis system, we measured the outside noises and partial discharge signals during practical operation by using the partial discharge diagnosis system of the Full A/D process. And we reviewed the confidence of the On-Line insulation diagnosis system by comparing and analyzing these data.

This study was undertaken to investigate dietary status, food habits, and nutritional knowledge of university students majoring in judo (n=239) and to evaluate the effect of dietary behavior on their athletic activities. Mean daily dietary intakes (3,854.0 kcal) were similar to mean daily energy consumptions (3,975.5 kcal). Average daily intakes of most vitamins and minerals were higher than Korean Recommended Dietary Allowances except for the intake of vitamin A. Self-confidence on judo affected dietary behavior of the subjects: Subjects who had more self-confidence on judo showed more interest in good nutrition and concerned more about foods which could promote their athletic activities. Many side effects were manifested after sudden weight control for judo competition during school days. Therefore, it is suggested that good education on nutrition is necessary not only for athletic students, but also for coaches and trainers of the students. Ten weeks of education on nutrition significantly improved both food habits and nutritional knowledge of the subjects. Food habits were positively correlated with self-confidence on judo. Therefore, it is suggested that improvement of food habits through good education on nutrition would be helpful to improve athletic activities of the students.

This paper presents a comparative study on the effectiveness of teaching an engineering course using English with Specific Purpose(ESP). A study was performed using student groups; one class using ESP, and one class conducted in English with an English text. The course conducted using ESP showed the greatest improvement in English writing and conversation, and the students reported a greatly increased confidence in their ability to function professionally using English. A self-assessment of each student was conducted before and after the courses. Prior to the course less than 10% in each group felt that they are able to: a) understand a textbook, b) write an email, c) generate a project report, or d) follow a lecture given in English. The survey at the end of the course showed that the ESP teaching style resulted in significant improvements in students ability and confidence with writing and speaking in English, whereas reading skills were similar for both groups. This is due to the ESP method, in which students are required to give presentations and keep journals in English. After a brief review of the ESP principles and a discussion of how they were implemented, the background data of the participants(students) are described. Finally, the end-of-semester survey highlights the efficacy of the ESP approach.

A convolution neural networks (CNNs) has demonstrated outstanding performance compared to other algorithms in the field of face recognition. Regarding the over-fitting problem of CNN, researchers have proposed a residual network to ease the training for recognition accuracy improvement. In this study, a novel face recognition model based on game theory for call-over in the classroom was proposed. In the proposed scheme, an image with multiple faces was used as input, and the residual network identified each face with a confidence score to form a list of student identities. Face tracking of the same identity or low confidence were determined to be the optimisation objective, with the game participants set formed from the student identity list. Game theory optimises the authentication strategy according to the confidence value and identity set to improve recognition accuracy. We observed that there exists an optimal mapping relation between face and identity to avoid multiple faces associated with one identity in the proposed scheme and that the proposed game-based scheme can reduce the error rate, as compared to the existing schemes with deeper neural network.
