Purpose: This study was done to examine physical, psycho-social, and individual factors influencing musculoskeletal symptoms among Korean military trainees. Methods: Using a correlation study design, military trainees who had completed almost of all the basic combat training (BCT) days were recruited from two military training units selected by convenience sampling. Data from 415 participants were analyzed. Results: Prevalence of musculoskeletal symptoms was 29.6% defined as a participant having pain or discomfort in one or more body parts during training hours for more than seven consecutive days. Back/pelvic (10.8%), knees (10.1%), shoulders (7.7%), feet/toes (5.6%), ankles (4.8%) were prone to musculoskeletal symptoms. Musculoskeletal symptoms appeared to be related to physical exertion during BCT, stress during BCT, social support from fellow trainees, or previous musculoskeletal injuries. In the logistic regression model, physical exertion during BCT (OR=2.27, 95% CI: 1.42~3.65), stress during BCT (OR=1.79, 95% CI: 1.15~2.78), and previous musculoskeletal injuries (OR=1.58, 95% CI: 1.01~2.47) were the significant factors affecting prevalence of musculoskeletal symptoms. Conclusion: Findings indicate that physical exertion and psycho-social stress should be managed to prevent musculoskeletal symptoms in military trainees with more attention being given to trainees having a history of musculoskeletal injuries.

Objective: Training-related injuries and attrition put an additional burden on police and military institutions. Preventing and minimizing musculoskeletal injuries is the primary concern of the Abu Dhabi Police. Therefore, this study aimed to evaluate the correlation between functional movement screen, lower-limb strength, Y-balance test, grip strength and vertical jump and the incidence of musculoskeletal injuries among Abu Dhabi police recruits. Design: Observational analytical study. Methods: An observational study was conducted on 400 male police recruits of Abu Dhabi Police Academy. Physical performance was assessed before the 16-weeks basic police training. Spearman's correlation evaluated the correlation between the performance parameters and the outcome measures and logistic regression predicted the risk factors associated with musculoskeletal injuries. Results: 149 (34.4%) participants reported at least one injury during the basic police training. Comparison between injured and non-injured participants showed significant difference in mean right Y-balance, back-leg-chest dynamometer, and vertical jump (p=0.02, p=0.02, and p=0.04, respectively). Spearman's correlation showed a significant negative correlation between risk of injury and back-leg-chest dynamometer and right Y balance (ρ= -0.11, p=0.03). Logistic regression showed that back-leg-chest dynamometer and right Y balance were significant predictors of injury (p =.036 and p=0.037; Odds ratio=0.96; 95% CI (0.92, 0.99) and Odds ratio=0.99; 95% CI (0.98,0.99). Conclusions: Our findings suggest functional movement screen and grip strength may not independently predict injury rates, balance and lower-limb strength needs to be considered in injury prevention strategies to reduce musculoskeletal injuries.

Objective : This study examined changes in the depression, anxiety, and suicidal ideation among Air Force conscripts during their Basic Military Training. Methods : Study participants were 500 Air Force conscripts. The study reviewed participants' self-reports on depression, symptoms of anxiety, and suicidal ideation at weeks 2, 4, and 6 of their training. Results : At weeks 2 and 4 of training, participants' mean BDI, BAI, and SCL-90-R depression and anxiety subscale scores were within the mild ranges. However, at week 6, those mean scores were in the normal ranges. The mean scores for the BDI, the BAI, and the depression and anxiety subscales of the SCL-90-R at weeks 2 and 4 were significantly elevated over the corresponding scores for week 6 (each F=8.78, df=2, p<0.01 ; F=22.16, df=2, p<0.01 ; F=11.08, df=2, p<0.01 ; F=3.42, df=2, p<0.05). Suicidal ideation, revealed by the mean BSIS score, fell within the normal range (F=9.94, df=2, p<0.01) throughout the study period. Conclusions : These results suggest that conscripts' initial levels of psychological distress in the form of depression and anxiety are slightly elevated, but most adapt to this distress during basic training. Therefore, more attention must be paid to the early stages of conscripts' basic training in order to address these concerns.

Every year, about 250,000 new recruits enter the military under the R.O.K military draft system. When the fresh soldier groups arrived at the Recruit Training Center, their supplies are distributed before they get basic military training. The supplies are divided by season, summer and winter. There are 14 class of summer items and 20 class of winter items, and the each class has about a few kinds of items. Totally, there are the hundreds kinds of supplies and the supplies distribution system is manually operated. However, in the current system, many problems such as spending a lot of time, manpower and high change rate due to the inaccurate distribution have been raised. This paper suggests the automated supplies distribution system to solve the above problems. We choose the appropriate facilities in the system by using the AHP(Analytic Hierarchy Process) and analyse the operating efficiency of the new system by simulation. The new suggested system shows about $39.25\%$ improvement in throughput and 3.75 times reduction of manpower compared to the current system.

The purpose of this study is to develop a method of applying AR(Augmented Reality)/VR(Virtual Reality) to educational and training systems from a comprehensive perspective, rather than applying AR/VR technology to specific education and training systems. We suggested whether to apply AR or VR technology to education and training system, the level of application of technology when constructing using AR/VR technology, and the criteria of priority among many education and training systems. To do this, we presented the framework of application of AR/VR technology, the evaluation criteria for selecting priority of education and training system applying AR/VR, and the systematic procedure for utilization of developed method. This study is significant in that it has developed a method to determine the direction of systematic AR/VR technology application for all education and training systems operated by the military or organization. This is expected to contribute to the overall efficiency of the organization in terms of economical utilization of the limited budget as well as the various benefits of utilizing basic AR/VR technology.

본 연구는 육군 교육훈련 효과를 향상시키기 위해 실장비, 가상현실, 동영상을 이용한 교육효과를 비교하여 어떤 방식의 교육이 우수한지를 검증하는데 있다. 육군은 실전적 훈련환경을 구현하기 위해 많은 노력을 기울였지만 1) 도시화에 따른 훈련장 부지확보의 제한, 2) 민원제기에 따른 대민갈등 심화, 3) 국방예산 확보에 어려움으로 인해 실전적 훈련환경을 제공하는 것은 점차 어려워지고 있다. 가상현실을 활용하면 실제 전장을 간접적으로 체험하고 비용을 절감할 수 있는 장점이 있다. 특히, 위험하거나 고가의 무기체계의 경우에는 가상현실을 적용한 훈련이 더욱 요구된다. 본 논문은 가상현실이 실제 무기체계에 비해 얼마나 효과적인지 연구한다. 연구결과, 가상현실 교육은 실장비 교육보다 효과가 다소 낮지만 동영상 교육보다는 효과가 높았다. 앞으로 이번 연구결과를 바탕으로 가상현실 기반의 교육효과 분석을 위한 기초자료로 활용이 가능할 것이다.

G-induced Loss of Consciousness(G-LOC) can be predicted by measuring Electromyogram(EMG) signals. Existing studies have mainly focused on specific body parts and lacked of consideration with quantitative EMG indices. The purpose of this study is to analyze the indices of EMG signals by human body parts for monitoring G-LOC condition. The data of seven EMG features such as Root Mean Square(RMS), Integrated Absolute Value(IAV), and Mean Absolute Value(MAV) for reflecting muscle contraction and Slope Sign Changes(SSC), Waveform Length (WL), Zero Crossing(ZC), and Median Frequency(MF) for representing muscle contraction and fatigue was retrieved from high G-training on a human centrifuge simulator. A total of 19 trainees out of 47 trainees of the Korean Air Force fell into G-LOC condition during the training in attaching EMG sensor to three body parts(neck, abdomen, calf). IAV, MAV, WL, and ZC under condition after G-LOC were decreased by 17 %, 17 %, 18 %, and 4 % comparing to those under condition before G-LOC respectively. Also, RMS, IAV, MAV, and WL in neck part under condition after G-LOC were higher than those under condition before G-LOC; while, those in abdomen and calf part lower. This study suggest that measurement of IAV and WL by attaching EMG sensor to calf part may be optimal for predicting G-LOC.
