  • Image training is a very important yet difficult state for automated visual inspection using computers. Because the size of parts for the recently produced PCB (Printed Circuit Board) becomes smaller and circuit patterns gradually become more complex, a difficult and complex training process is becoming a big problem within an industry where development cycle for new products is short and various products must be inspected. This research produced a reference image by using CAD (Gerber) file which becomes a standard for PCB automatic visual inspection. Reference image from a Gerber file guarantees PCB patterns with no defects. Through system implementation and experimentation, Gerber file is used in order to propose a plan which allows an easy training process for PCB automatic visual inspection system.

  • The cooling stage greatly affects the product quality in the injection molding process. The cooling system that minimizes temperature variance in the product surface will improve the quality and the productivity of products. The cooling circuit optimization problem that was once solved by a response surface method with 4 design variables. It took too much time for the optimization as an industrial design tool. It is desirable to reduce the optimization time. Therefore, we tried the back-propagation algorithm of artificial neural network(BPN) to find an optimum solution in the cooling circuit design in this research. We tried various ways to select training points for the BPN. The same optimum solution was obtained by applying the BPN with reduced number of training points by the fractional factorial design.

  • Purpose : The purpose of present study was to determine effects of a task-oriented circuit training(TOCT) for lower limb on walking ability after stroke. Methods : Twenty one chronic stroke patients participated. Participants were randomly divided into either TOCT group or control group(11 experimental, 10 control). All of participants were in-patients at local rehabilitation centre and had been receiving a traditional rehabilitation program, five days a week. TOCT group have additionally undergone for four weeks, three days a week, the TOCT program but control group was not received any additional program except the traditional rehabilitation program. The 10 m walking test (10MWT), the 2 min walking test (2MWT), the step test (ST) and the figure-8 walking test (F8WT) to measure a walking ability were carried out twice before and after training. Results : After participation in the program, subjects of TOCT demonstrated a significant improvement in the scores of the 10MWT, 2MWT, the ST, the F8WT. The control group had no change on the any tests. After the training, the results to improve significantly in TOCT group compared to post-test of control group were the time of 10MWT and the time and the step of curved walking of F8WT. Conclusion : The present study suggests that the TOCT program may become a useful strategy for enhancing walking ability in the rehabilitation of stroke patients.

  • Walt Disney Feature Animation released high quality films such as 'Frozen', 'Big Hero 6', 'Wreck-it Ralph', 'Zootopia', 'Moana', 'Frozen 2' and not only got high score in box office but showed great CG and visuals. However, making feature animation requires a lot of time, money, and efforts so it is very important to support studios' artists to finish each show within limited budget and time. This paper shows artists' training program such as 'Short Circuit' and 'Bootcamp' that walt disney feature animation provides their artists to improve their creativity and do their jobs artistically and efficiently. Disney's training program not only provides artists various training classes but gives them chances to work on short animation which enhances artistic skills and enable them to work in different departments and experience different tasks. This paper also explains some training cases of CG studios in South Korea and Disney Animations' in-house tools.

  • We have developed Logic Design Training Kit for studying, actual training, designing of FPGA(Xillinx) or CPLD(ALTERA CPLD), the Digital Logic Device. This training kit has 12 matrix keys, RS232 port for serial communication and uses LED array. six FND(Dynamic), LCD as display part. That is standard specification for digital logic training kit. Special point of this kit is that we make two logic device trainig kit. This two logic device kit have more smaller and simple architecture because only uses one chip. That chip already includes a lot of functions that need for training kit, such as : complex logic circuit needed the two kind of logic devices, 16 way of system clock deviding function, serial communication interrupt....etc. We called that one chip is Center Bridge Chipset ; Xillinx FPGA Spartan2. User can select between using one device of FPGA or CPLD, or uses both them. Because of, Center Bridge Chipset has profitable architecture. it can work as Logic Device's networking with Master-Slave connection When using both logic devices.

  • PURPOSE: The purpose of this study was to investigate whether a circuit aerobic exercise program positively affects pulmonary function and gait endurance in chronic stroke patients. METHODS: Twenty-four chronic stroke patients were allocated equally and randomly to an experimental group (n=12) or a control group (n=12). All participants received 60 minutes of comprehensive rehabilitation treatment, the experimental group additionally performed a circuit aerobic exercise for 30 minutes, while the control group additionally performed a general aerobic exercise, i.e., gait training on the treadmill for 30 minutes. These 30-minute exercise sessions were held three times per week for six weeks. Pulmonary function was assessed using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV), and gait endurance was assessed using the 6-minute walk test (6MWT). RESULTS: In the both groups, FVC, FEV1, MVV, and 6MWT were significantly increased after training. Members of the experimental group showed significant improvements in FVC, FEV1, and MVV, and significantly greater improvements than controls (p<.05). However, 6MWT improvements were not significantly different in the two groups (p>.05). CONCLUSION: The devised circuit aerobic exercise program offers an effective rehabilitation aerobic exercise for improving pulmonary function and gait endurance in patients after chronic stroke.

  • The purpose of this study was to examine the effects of group task-oriented circuit training (TOCT) based on motor learning applied in conjunction with physical and occupational therapy on functional activity, activities of daily living (ADLs), and quality of life in individuals with chronic stroke. Six chronic stroke patients participated for a duration of 31 weeks. Treatment outcomes were assessed via Chedoke-McMaster Stroke Assessment, the Berg Balance Scale, the Assessment of Motor and Process Skill (AMPS), and the Stroke Impact Scale pre- and post-intervention. The participants exhibited significant improvements in impairment, static and dynamic balance, and mood and emotion after group TOCT. The results of AMPS indicated an improvement in the motor area in 3 of the subjects. In the process area, 4 of the subjects exhibited improvement. The results of this study suggest that TOCT is beneficial to physical functions for chronic hemiparetic stroke patients in community-dwelling.
