  • Gender prediction accuracy increases as convolutional neural network (CNN) architecture evolves. This paper compares voting and ensemble schemes to utilize the already trained five CNN models to further improve gender prediction accuracy. The majority voting usually requires odd-numbered models while the proposed softmax-based voting can utilize any number of models to improve accuracy. The ensemble of CNN models combined with one more fully-connected layer requires further tuning or training of the models combined. With experiments, it is observed that the voting or ensemble of CNN models leads to further improvement of gender prediction accuracy and that especially softmax-based voters always show better gender prediction accuracy than majority voters. Also, compared with softmax-based voters, ensemble models show a slightly better or similar accuracy with added training of the combined CNN models. Softmax-based voting can be a fast and efficient way to get better accuracy without further training since the selection of the top accuracy models among available CNN pre-trained models usually leads to similar accuracy to that of the corresponding ensemble models.

  • The service industry needs face-to-face customer service, which suggests the need for education training for workers. In other words, it is meaningful to look at whether education training for workers has a positive impact on the organization's performance. The success through education training will be due to the combined role of various factors. In this regard, the study focuses on how the attitude of workers in education training can play a role rather than just verifying the effectiveness of education training alone. As a result of the study, it was found that an employee's attitude toward education training, which was considered necessary to produce more effective results, was a regulator to further improve the educational satisfaction of training. After all, the more positive workers are about education training, the better workers' job performance can be. Therefore, promoting employee's education attitude before education training needs to be a priority, and further studies may call for more in-depth examination of the role of education training attitude.

  • This paper proposes an efficient method for improving the training performance of the neural network by using a hybrid of a stochastic approximation and a backpropagation algorithm. The proposed method improves the performance of the training by appliying a global optimization method which is a hybrid of a stochastic approximation and a backpropagation algorithm. The approximate initial point for a stochastic approximation and a backpropagation algorihtm. The approximate initial point for fast global optimization is estimated first by applying the stochastic approximation, and then the backpropagation algorithm, which is the fast gradient descent method, is applied for a high speed global optimization. And further speed-up of training is made possible by adjusting the training parameters of each of the output and the hidden layer adaptively to the standard deviation of the neuron output of each layer. The proposed method has been applied to the parity checking and the pattern classification, and the simulation results show that the performance of the proposed method is superior to that of the backpropagation, the Baba's MROM, and the Sun's method with randomized initial point settings. The results of adaptive adjusting of the training parameters show that the proposed method further improves the convergence speed about 20% in training.

  • The study examines the influence of individual characteristics, training content, and manager support on the effectiveness of on-the-job (OJT) training in the banking and finance industry. A simple random sampling technique was used to select the samples. Questionnaires were distributed to respondents in order to obtain the data. Using cross-sectional data obtained from 396 respondents in Bank A in Malaysia, the multiple regression results show that self-efficacy, motivation to learn, training content, and manager support have positive influence on OJT training effectiveness. Among all these factors, manager support is very highly correlated with OJT training effectiveness. The findings have given fruitful insight of the crucial roles of OJT training in the respective bank, particularly to bring forward the roles of systematic design and implementation of OJT training. This study is not only expanding knowledge in OJT and training, but offers managers practical insights in developing good OJT training program by considering employees need, capabilities, skills and job requirement. Furthermore, this study also provides a valuable framework in identifying the effectiveness of OJT training program for certain jobs. Further discussion of the research findings and its implications to theoretical knowledge of training and managers are promised at the end of the article.

  • The purpose of this study was to determine the effects of weight shift training with joint mobilization on the ankle joint passive range of motion (PROM), balance capacity and gait velocity in hemiplegic patients. Fourteen subjects were randomly assigned to either the experimental group (EG) or the control group (CG), with seven subjects in each group. The EG received weight shift training with joint mobilization in the paretic leg's subtalar joint in order to increase ankle dorsiflexion. The CG received general physical therapy training. Both groups received training five times a week over a period of two consecutive weeks. The figures for PROM of ankle dorsiflexion on the paretic leg, the functional reach test (FRT), the timed up and go (TUG) test, and gait velocity were recorded both before and after the training sessions for both groups. The EG's results in gait velocity, the FRT and the TUG test improved after training (p<.05). The PROM of ankle dorsiflexion improved both in the EG and the CG (p<.05), the EG demonstrated a significantly higher increase (p<.05) than that of the CG. The results of this study suggest that increased joint mobilization positively affects balance and gait velocity of hemiplegic patients. Further studies with a greater sample size are necessary in order further prove the accuracy of the results of this study.

  • Over the past decade, driven by advances in educational theory and pressures for efficiency in the clinical environment, there has been a shift in surgical education and training towards enhanced simulation training. Microsurgery is a technical skill with a steep competency learning curve on which the clinical outcome greatly depends. This paper investigates the evidence for educational and training interventions of traditional microsurgical skills courses in order to establish the best evidence practice in education and training and curriculum design. A systematic review of MEDLINE, EMBASE, and PubMed databases was performed to identify randomized control trials looking at educational and training interventions that objectively improved microsurgical skill acquisition, and these were critically appraised using the BestBETs group methodology. The databases search yielded 1,148, 1,460, and 2,277 citations respectively. These were then further limited to randomized controlled trials from which abstract reviews reduced the number to 5 relevant randomised controlled clinical trials. The best evidence supported a laboratory based low fidelity model microsurgical skills curriculum. There was strong evidence that technical skills acquired on low fidelity models transfers to improved performance on higher fidelity human cadaver models and that self directed practice leads to improved technical performance. Although there is significant paucity in the literature to support current microsurgical education and training practices, simulated training on low fidelity models in microsurgery is an effective intervention that leads to acquisition of transferable skills and improved technical performance. Further research to identify educational interventions associated with accelerated skill acquisition is required.
