  • In pedestrian detection applications, one of the most popular frameworks that has received extensive attention in recent years is widely known as a 'Hough forest' (HF). To improve the accuracy of detection, this paper proposes a novel split function to exploit the statistical information of the training set stored in each node during the construction of the forest. The proposed split function makes the trees in the forest more robust to noise and illumination changes. Moreover, the errors of each stage in the training forest are minimized using a global loss function to support trees to track harder training samples. After having the forest trained, the standard HF detector follows up to search for and localize instances in the image. Experimental results showed that the detection performance of the proposed framework was improved significantly with respect to the standard HF and alternating decision forest (ADF) in some public datasets.

  • This study reviewed elementary school teachers' opinions on the integrated curriculum in terms of the 2007 curriculum draft revision, as well as surveying their requests in regards to the 2009 curriculum draft revision. This study was conducted by means of questionnaires with 183 elementary school teachers. Most agreed that a theme-based-integrated curriculum was better than studying separate subjects, but most also argued that it takes considerable time reorganize and implement the integrated curriculum. Successful implementation also requires further teachers' training and their cooperation. The theme-based texts have already been in use from 2009 for first and second grades. Teachers prefer training courses which focus on the integration of the subjects, understanding the nature of each subject and sharing ideas and tips. Such training can assist in identifying the gaps between the curriculum plans and real classroom applications. Furthermore it can present clear guidelines to help ensure that the curriculum is organized effectively and well managed. Networks of specialized personnel or programs were also found to be very good resources both in and out of school.

  • An 'associative cube', a class of auto-associative memories, is revisited here, in which training data and hidden orthogonal basis functions such as wavelet packets or Fourier kernels, are combined in the weight cube. This weight cube has hidden units in its depth, represented by a three dimensional cubic structure. We develop an unsupervised incremental learning mechanism based upon the adaptive least squares method. Training data are mapped into orthogonal basis vectors in a least-squares sense by updating the weights which minimize an energy function. Therefore, a prescribed orthogonal kernel is incrementally assigned to an incoming data. Next, we show how a decoding procedure finds the closest one with a competitive network in the hidden layer. As noisy test data are applied to an associative cube, the nearest one among the original training data are restored in an optimal sense. The simulation results confirm robustness of associative cubes even if test data are heavily distorted by various types of noise.

  • Recent evidence indicates that the ephrin receptors and ephrin ligands (Eph/ephrin) expression modulate axonal reorganization and synaptic plasticity in stroke recovery. To investigate the effect of task-specific training (TST) on Eph/ephrin expression in the corticospinal tract (CST) after stroke, we compared Eph/ephrin expression in the peri-infarct cortex, pyramid, and spinal cord of a photothrombotic stroke model of rat brains treated with or without TST. The TST treatment showed significantly better recovery in the behavioral tests compared with no treatment. The significant upregulation of ephrin-A1 and ephrin-A5 observed in activated astrocytes of the CST at 2 weeks' post-stroke was decreased by TST. At 5 weeks, post-stroke, the elevated ephrin-A5 levels were decreased in the ipsilateral pyramid and spinal cord by TST. Glial fibrillary acidic protein was upregulated concomitantly with the altered ephrin expression after stroke, and the expression of these proteins was attenuated by TST. These data suggest that TST alters the expression of ephrin ligands in the CST after stroke.

  • After 1990, Food service industry is growing up so fast and asking a lot of employee to be able to work this one. Our society will continue the growth of quantity and quality of food service industry with closing to the developed country and increasing the national income and leisure time. But our present culinary education system cannot gain the efficient of professional training to adopt food service industry without re-education and training. So, in our culinary education we have to be introduced new education system which is used effectively as a professional culinary education system in C.I.A. This system has merit to be able to teach step by step from basic to advanced course. Also Most of school system(management purchasing, human research, school life, etc.) is focused for culinary education. But, although this system has a lot of merits, it is too early toy us to adopt in our culinary education system. Because our education system has too much limited educational administrations of government and school for introducing new education system. The present educational situation is not enough to have facilities and financial support Finally, our culinary educational system have to change to right direction to improve in culinary education. Block system is one of the well-prepared system. But we need to administrational support of government and school to be able to adopted to our culinary educational system.

  • In order to provide a safe free-weight-training environment to people without workout trainers, we suggest a smart bench press machine with an automatic weight control system sensitive to user tiredness. Physical weight plates on the machine are replaced with a hydraulic cylinder as a press load and the cylinder knob is coupled with a step motor to change its tensile force automatically in-between lifting exercises. Three subjects participated to verify the usability of the smart bench press machine. They were asked to lift a 6-RM press load 10 times with 3 different lifting conditions: 1) no assistance, 2) a human assistance, and 3) the automatic weight control. All subjects were not able to complete the 10 sets without assistance due to tiredness, but they finished the full sets under the two assistive conditions. Average lifting speeds under the automatic weight control condition showed the most consistent level. Normalized quasi-tension data based on surface electromyogram signals of both Pectoralis Majors revealed that the subjects maintained the target muscle activation level above 50% but not more than 80% throughout the 10 sets. Therefore, the smart bench press machine is expected to both keep pace with the lifting exercise and reduce risk of injuries due to excessive muscle tensions.

  • Purpose : This study aimed to identify whether resistance exercise using elastic bands for six weeks can improve muscle strength, muscle tone, balance, and gait in patients with stroke. Methods : In total, 35 patients with stroke were randomly divided into three groups: resistance exercise using elastic band training combined with less affected side training group, more affected side training group, and both sides training group. Muscle strength, muscle tone, balance, and gait were assessed using a hand-held dynamometer, the modified Ashworth scale, the Berg Balance scale (BBS), and wireless 3-axis accelerometer, before and after training. Results : All three groups showed a significant increase in muscle strength of the lower extremity after training, and there was a significant difference among the groups. There was no change in muscle tone in all three groups. BBS scores increased significantly in all three groups after training, but these scores were not significantly different. The gait speed increased significantly in all three groups after the training, but the difference was not significant. The cadence increased significantly in Group 2 after training; however, there was no significant difference between Groups 1 and 3. There were no significant differences between the groups before and after the training. Step length increased significantly in Groups 2 and 3 after the training, but it was not significantly different in Group 1. After training, Groups 2 and 3 were significantly greater than Group 1 in the change in step length. Conclusion : The results show that resistance exercise using elastic bands can improve strength, balance, and gait in patients with chronic stroke. Especially, more affected side training was more effective in improving muscle strength than less affected side training. More affected side and both sides training are thought to be more effective than less affected side training to improve step length.

  • Global economic recession, global market reduction, and the deteriorating economic recession are forcing the industry to reconsider the business plan and strategy related to supply chain regardless of the size of the companies. During the economic recession caused by financial anxiety, development of international collaborative producer is the key theme for a manufacturing industry to get over the situation. Especially, development of high-skilled people who are capable of handling global manufacturing management is the key factor in China which shifted from a world factory to a world market. In this background, we started the international project of global manufacturing education and training for Chinese company managers from 2009. In this paper, based on the research conducted by the universities and companies in China, a design of global manufacturing education and training is proposed. This presented design is based on the theory of Japanese production strategy and investigation of actual conditions for Chinese companies and the research methodology of business management practice with efficiency and productive for international level management organization. The effectiveness of the education design is evaluated by applying the international education and training project of Aoyama Gakuin Human Innovation Consulting Inc. and Vigor Management Technology Association.

  • This case study aims to investigate how a primary English teacher's professional development was pursued through novice teacher mentoring after the six-month intensive in-service teacher training program(IIETTP). The teacher was involved in mentoring two novice teachers working at the same school. They observed each other's classes and exchanged their views on the classes, focusing on areas to be improved. The observation was done within a framework that consisted of pre-, during- and post-observation sessions. Data was gathered through retrospective entries kept after the post-observation meetings. The entries were categorized according to their saliency, frequency and recurring patterns identified. The findings reveal that learning from the training course could be applied professionally and could serve to bridge the gap between training and teaching. It is also shown that the mentee teachers' professional development was enhanced and the mentor teacher herself benefited from the collaborative learning process involved with working with the novice teachers. Some suggestions are made for the effective implementation of school-based teacher development programs after the IIETTP.
