Purpose: This study aimed to assess the effectiveness of gait training with the use of an electromechanical gait trainer with functional electrical stimulation (FES) for patients that had undergone subacute stroke. Methods: The study subjects included nine subacute stroke patients of the Korea National Rehabilitation Center in Seoul, Korea. Outcome was measured using the timed Up and Go test, Fugl-Meyer-L/E assesment, with determination of the comfortable maximal gait speed, composite spasticity score, functional ambulatory category and Berg balance scale. All measured scores were recorded before, during, and after rehabilitation and at an eight-week follow-up. Results: Patients who received electromechanical-assisted gait training in combination with FES after subacute stroke were more likely to achieve independent walking, functional activities, balance and gait speed. Conclusion: The outcome of our gait-training program demonstrates that it may be practical to integrate FES into electromechanical gait training without any adverse effects. However, further randomized controlled studies are needed to evaluate if patient outcome after combined training is superior to outcome after the use of electromechanical gait trainer treatment alone or conventional gait training alone.

Purpose : This study aims to investigate the rating of perceived exertion (RPE) and muscle activity of the inspiratory primary and accessory muscle during breathing exercise with different air hole diameters of the inspiratory muscle trainer (IMT). Methods : The Borg's scale and surface electromyography (EMG) was used to collect data of the RPE and muscle activity of the inspiratory primary the external intercostal (EI) and diaphragm (DIA) and accessory muscles anterior scalene (AS), sternocleidomastoid (SCM), pectoralis major (PM), and upper trapezius (UT) muscles during breathing exercise with different air hole diameters (6 mm, 4 mm, and 2 mm) of the IMT in healthy young male subjects. Results : The RPE and muscle activities of the AS, SCM, and UT are increased significantly in accordance to the decreasing diameter of air hole of air tip in IMT. However, there are no differences in the muscle activities of the PM, EI, and DIA based on differences of diameters of air hole of air tip in IMT. Conclusion : The smaller the diametr of IMT air-hole, RPE and muscle activities of AS, SCM and UT were increased. Therefore, further study would be necessary to investigate the proper intensity and relaxation posture for the exercise protocol to strengthen the inspiratory primary muscles.

Currently, there are two types of trainer in Korea : basic and advanced. Both models have been in operation for more than 10 years, and compared to the early stage of operation, reliability has gradually improved and failure rates have also entered a trend of stabilization. Therefore, it is necessary to extend the maintenance period considering economic feasibility. This study investigates the three maintenance period calculation methods: NAVAIR 00-25-403 [17], DOD, U.S. [4], CERL and US Army [3], with intention to extend the maintenance period of the trainer from current 200 hours to 400 hours. In addition, the maintenance period was calculated by the three methods with actual operational data. Common standards and procedures were established to apply operational data to the existing maintenance period calculation methods, the required reliability indicators were derived, and the maintenance periods was calculated based on the results, additionally, a review on the field applicability of the three maintenance cycles was conducted. An on-site interviews were conducted with the calculation results, and 11 out of the 15 items were expected to be extended by 400 hours. It was suggested that the remaining 4 items could be extended to 400 hours by supplementing the inspection method through additional analysis such as functional analysis, inspection content verification, and site connection.

In this research, we study on to find the inter-relation among education service quality and customer satisfaction and re-use focusing on E life-long education center. Education service quality consists of four factors such as training center's facility, trainer, employee's service and operating service. As like the results of this research, we found that three factors of education service quality such as facility, trainer and operating service give a positive effect to customer satisfaction and also we found that customer satisfaction gives a positive effect to re-use.

The purpose of this study was to investigate early childhood teachers' self-image by metaphoric pictures of occupation. The sample consisted of 311 early childhood teachers in kindergarten or day-care center. Teachers were asked them to match their image of themselves as early childhood teachers with metaphoric pictures of occupation. The major results were as follows. First, kindergarten teachers chose conductor, entertainer, nurse, sculptor, shopkeeper, animal trainer, judge by turns and day-care center teachers chose nurse, sculptor, conductor, entertainer, shopkeeper, judge, animal trainer by turns. Second, the reason for selecting the metaphoric pictures of occupation as their self-image was analyzed into 16 categories.

FAA AC120-40B Level D flight dynamics model for T-50 Full Mission Trainer was successfully developed. Since AC120-40B Level D requires the quantitative validation tests for simulation model compared with flight test data, T-50 flight test data for each validation test item was gathered, and also automatic test environments which include AFT (Automatic Fidelity Tester) and STA (Simulation Test Analyzer) were developed. The final test results after the iterative test-tuning processes were all within the tolerances specified in AC120-40B Level D. Qualification Test Guide, QTG contains the detail test processes and results.

Icing cloud generation system was developed to perform the in-flight icing simulation test for T-50 Supersonic Jet Trainer on the ground. The developed system successfully generated the almost natural icing cloud in the super-cooled state (liquid state) below freezing point and with the required LWC (Liquid Water Content). For full-scale aircraft icing test, an icing scaling method was adopted due to the limitation of wind generation speed with open-circuit type blower and its applicability was experimentally verified. Under the required in-flight icing condition based on the icing scaling method, T-50 aircraft subsystems were successfully operated and functionally checked.

The environmental tests are one of the key branches of the reliability tests. The purpose of the high/low environmental test of KT-1 Export Version Trainer is not only based on meeting the compliance of the reliability, customer satisfaction, but also for the expansion of its export. Amongst many existing environmental tests, the high and low temperature tests are considered as the two most important tests. The tests are considered and tailored to the high and low temperature methods of MIL-STD-810H. This paper proposes the tailoring processes and the results of High/Low temperature conditions, test procedures, and test profiles for the aircraft. Additionally, this paper is described by considering the view of MIL-STD-810H.
