육군의 화력장비 정비교육 중 특기병 교육은 실습용 장비가 부족하고 많은 교육생으로 실습기회가 적고 정비실습 시 안전사고 발생위험이 높아 실질적인 실습이 제한적이고 반복 실습이 어렵기 때문에 교육적 효과가 미비한 게 현실이다. 따라서 실제와 같은 체험훈련으로 교육성과를 높이는 훈련시스템이 필요하다. 본 연구에서는 시공간을 초월하여 훈련비용을 낮추고 실제와 같은 체험훈련을 할 수 있으며, 표준 정비매뉴얼이 반영되고 팀워크를 이루어 훈련할 수 있는 가상훈련시스템을 제안한다. 가상훈련시스템은 시공간을 초월하여 비용을 낮추고 실제와 같은 훈련이 가능한 시스템으로 본 연구에서 제안한 3차원 디스플레이 시스템인 HMD를 이용한 1인칭 시점의 가상훈련시스템은 육군 화력장비 정비교육에 적합한 시스템이며 확장성이 좋기 때문에 다른 장비와 타군의 정비교육에도 활용되어 군의 정비능력 향상에 크게 도움이 될 것으로 기대한다.

Background: The purpose of this study was to investigate the effects of Progressive muscle relaxation training on pain, Korean version of Oswestry disability index (ODI) and psychological level in chronic low back pain patients with somatization. Methods: A total of 30 subjects were treated with the experimental group (n=15) and conservative physical therapy (n=15). The experimental group was trained with progressive muscle relaxation (PMR), and the control group was treated with conservative physical therapy. Physical factor treatment was applied for 60 minutes by hot pack, electrotherapy and ultrasound. Both groups performed three times a week for six weeks. VAS, ODI, psychological level measurements were taken before and after intervention. Results: There was a significant difference in VAS (p<.05) and ODI (p<.01) between experimental and control group. At the psychological level, there were significant differences in somatization (p<0.01) and depression scales (p<.01), but not in anxiety. Conclusion: As a result of this study, the degree of pain was decreased, the level of back pain dysfunction was improved, and the somatization scale and depression scale were decreased by gradual muscle relaxation therapy.

Purpose : The purpose of this study was to compare the effectiveness of both neuromuscular electrical stimulation(NMES) and isometrical exercise(IE) to strengthen the quadriceps femoris muscle. The relationships between the strength changes and the relative force and duration of training contractions were also studied. Methods : The subjects were divided into three group. The control group(n=6) received no exercise and/or stimulation. The isometric exercise (IE) group(n=6) performed maximum isometric contractions, and the neuromuscular electrical stimulation(NMES)(n=6) engaged electrically stimulated isometric contractions, three days a week for four weeks. Results : Results showed that both IE group and NMES group were found to have an increase in strength significantly greater(p<0.05) than the control group at 4 week. But between IE group and NMES group were not found to have an difference in strength significantly. Conclusion : The relative increase in isometric strength, using IE and NMES, may be determined by the ability of the subjects to tolerate longer and more forceful contractions. Suggestions for further research and implications for the clinical of IE and NMES for strength-training are discussed.

Background: Approximately 30% of people suffer from chronic neck and shoulder pain. Chronic neck and shoulder pain arise due to the exposure to continuous low loading and monotonous work. This is a common musculoskeletal disorder in a society. As physical therapists, we should give appropriate treatment to these people. Methods: A total of 26 patients with chronic neck and shoulder myalgia were randomly allocated into two experimental groups. First, 13 patients received shoulder strength training, while the other 13 patients received cervical mobilization. Outcome measures included bilateral pressure pain threshold by using an algometer at upper trapezius, visual analogue scale (VAS) to express their pain scale, and muscle tension by using myoton pro device pre-intervention and after the final treatment. Results: The VAS and muscle tension in upper trapezius significantly decreased (p<.05) in both groups; however, no differences between two groups were observed (p>.05). The pressure pain threshold in upper trapezius significantly increased (p<.05) in both groups; yet, again, the differences between the groups did not reach statistical significance (p>.05). Conclusion: As methods of treatment, shoulder-specific strength training and cervical mobilization can be appropriate approaches to the treatment of neck and shoulder musculoskeletal disorder.

Purpose: This study aimed to examine the effects of mirror-neuron-system-based action observation physical training on improvements in upper extremity functions and daily living activities in chronic stroke patients. Methods: Ten chronic stroke patients were randomly selected. As a therapeutic intervention, along with conventional occupational therapy, the patients engaged in action observation physical training through repeated imitation practices after they viewed a video. The therapeutic intervention was implemented for 20 minutes, three times each week for eight weeks. A Manual Function Test (MFT) was conducted to compare upper extremity functions before and after the therapeutic intervention, and the Modified Barthel Index (MBI) was used to compare the ability to perform daily living activities. Results: Significant improvements in upper extremity motor functions and the ability to perform daily living activities were shown after the intervention. The subjects' left upper extremity motor functions and ability to perform daily living activities showed significant improvement after the intervention. Conclusion: The study's results indicate that action observation physical training based on the mirror neuron system improves chronic stroke patients' upper extremity motor functions and their ability to perform daily living activities. Therefore, action observation training has positive effects on the functional recovery of chronic stroke patients.
