The purpose of the study is to show the need for the development of standard materials which can be used for flight training and pilot practical tests in the future. In this paper the flight training and evaluation references of flight training institutes certified by the Ministry of Construction and Transportation(MOCT) are compared with references of the international organization such as ICAO and FAA. As a result it is found that the flight schools certified by the MOCT have used different references for flight training and evaluation. Therefore, this study suggests creation and operation of an expert advisory group to develop new standards for flight training and evaluation, so called " Flight Training Manual", in Korea.

Objectives: Korean Medicine Doctors (KMDs) have treated patients with obesity using a holistic approach with a multicomponent approach on counseling. However, there is currently no data regarding KMDs' counseling practices for weight loss. We conducted a retrospective chart review to better understand the Korean medicine counseling practice for weight loss. Methods: Twenty-one KMDs were involved in this project as practitioners. The contents of counseling were categorized based on patterns according to the counseling manual for the standardized management of obesity in Korean Medicine. Results: The counseling was conducted based on the theory of Korean medicine and the contents of counseling were different from patterns. However, the quality of the counseling were different from each KMD, and the counseling were focused on evaluating patient conditions and not on providing specific recommendations for lifestyle changes. Conclusions: Therefore, specific guidance of counseling for healthier lifestyle and dietary habits, and the training of the standardized manual training are needed.

As the workers are getting old, they need to be expert in their fields. Expertise is an invaluable means of shipbuilding industries because of the technological advancements. Therefore, the workers have to attend training seminars and upgrade their technical knowledge. In shipbuilding industries, most workers operate transporters based on experience not on learning from specialization in the shipyard. It is needed for the workers of transporters to be educated technical manual and system. Thus, this research shows that educational system which is interactive and very effective with Augmented Reality(AR) for the non-specialist workers. The educational interactive system based on AR is very supportive and worth for the workers. This study considers the system which makes the workers reduce malfunction of the products and mistakes.

Purpose: This study attempts to understand the effect of stabilization exercise of biofeedback scapular on muscle activity and functional evaluation of the upper extremity in stroke patients. Methods: Patients were divided into two groups; a biofeedback scapular stabilization exercise group comprised of 8 patients and a task-oriented training group including another 8 patients, and 30-minute exercise was performed 5 times a week for 8 weeks. Electromyogram was used to measure muscular activity of lower trapezius, deltoid middle, and serratus anterior. Fugl-Meyer Assessment and Manual Function Test were used to evaluate functions of the muscles mentioned. Results: Significant difference was observed in the comparison group before and after exercise in muscular activity of lower trapezius, deltoid middle, and serratus anterior, Fugl-Meyer Assessment, and Manual Function Test. Conclusion: Therefore, we could see that biofeedback scapular stabilization exercise is more effective than task-oriented training in facilitating muscle activation and functional capacity of upper limb.

Purpose : The purpose of the present study is to examine the effects of VR training with FES on improving the muscle strength, AROM, and function of the upper limb joints in patients with chronic stroke. Methods : The present study makes use of a pre-post control group design. Thirty patients with chronic stroke were randomly assigned to two groups according to treatment method - the VRFES group and the control group. The VRFES group received 15 minutes of VR training and 15 minutes of FES treatment. The control group received 15 minutes of conservative physical therapy and 15 minutes of VR training. All subjects received 30 minutes of treatment, three times a week, for eight weeks, which amounted to 24 sessions of training. The muscle strength, AROM, and function of the upper extremities were measured before the training and eight weeks after. Upper limb muscle strength was tested using the Digital Manual Muscle Tester while AROM was measured using the Digital Dual Inclinometer. The clinical assessment tools for upper extremity function included the use of the Manual Function Test and the Jebsen-Taylor Hand Function Test. Results : Both groups exhibited great improvements in muscle strength and upper extremity function during the intervention period. The VRFES group exhibited a significant difference in muscle strength, AROM, and function of the upper extremities in comparison with the control group(p<.05). Our results reveal that VRFES is more effective for the muscle strength, AROM, and function of the upper extremities in patients with chronic stroke. Conclusion : VRFES treatment will be used as an important intervention for improving the muscle strength, AROM, and function of the upper extremities in patients with chronic stroke and achieving the functional recovery of the upper extremities.

Background: This study aimed to determine the effects of training on breathing re-education on pain and dysfunction levels, posture, quality of life (QoL), and pulmonary function in patients. Methods: This study included 34 patients with chronic neck pain and upper thoracic breathing pattern were included. The participants were assigned to either the routine physical therapy program (RPTP) (CG; n=17) or RPTP and breathing pattern re-education training (EG; n=17). The CG and EG groups performed RPTP for 40 minutes, and only the EG groups performed breathing re-education training for 10 minutes. Exercises were performed thrice weekly for both groups. Level of pain and dysfunction, posture, QoL and pulmonary function status were assessed before and after the intervention. Results: After four weeks of intervention, numeric pain rating scale (NPRS), Korean version of neck disability index, cranio-vertebral angle, cranial rotation angle, and 12-item short form health survey-physical and mental component summaries had significant differences before and after intervention in both groups (p<.01). However, only NPRS, forced vital capacity, forced expiratory volume in 1s, and maximum voluntary ventilation showed significant interactions between the two groups and measurement time (p<.01). Conclusion: Breathing re-education training and RPTP may be optimal for patients with chronic neck pain and may be more effective in improving neck pain and pulmonary function.

It is difficult to obtain a swinging-up control sequence of a one-link pendulum analytically or numerically. In this paper, we obtain a proper control sequence through manual control experiments. However, no proper control sequence will be obtained if the rotational velocity of the pendulum is fast for the human operator. To overcome such a disadvantage, we propose a method for training the operator by using a pendulum simulator.
