Deep learning models require high computing power due to a substantial amount of computation. It is difficult to use them in devices with limited computing environments, such as coastal surveillance equipments. In this study, a lightweight model is constructed by analyzing the weight changes of the convolutional layers during the training process based on MobileNet and then pruning the layers that affects the model less. The performance comparison results show that the lightweight model maintains performance while reducing computational load, parameters, model size, and data processing speed. As a result of this study, an effective pruning method for constructing lightweight deep learning models and the possibility of using equipment resources efficiently through lightweight models in limited computing environments such as coastal surveillance equipments are presented.

War field differs from conventional military education and training environments. Warfighter may confront frequently unexpected physical and psychological stimulation. Cumulative psychological stress and physical fatigue can be causes of mood distortion, declined alertness, and decreased combat capability in warfighters. Countermeasures of combat stress and fatigue is very important for keeping combat capability and saving of life. Here in, the countermeasures of combat stress and fatigue have reviewed, and limitation and the direction of research and development of countermeasures of combat stress and fatigue are proposed.

Objectives: Weight control practices are common in combat sport athletes. This study was performed to examine nutrient intakes of male college combat sport athletes (taekwondo, boxing, judo) by weight control (WC) status. Methods: Subjects were male combat sport athletes (n=90) from colleges in Gyeonggi Province. Survey was conducted during 2016. Questionnaire included general characteristics, weight control, and dietary intakes during the period of training, weight control, weigh-in ~ before competition and between competitions. Subjects were grouped into high- and normal WC groups. T-test, ${\chi}^2-test$, Fisher's exact test and ANCOVA were used to analyze the data. Results: During training, energy intake was 75.4% of EER and C:P:F ratio was 57.5:13.9:28.7. Iron and zinc intakes were different by WC groups (p<0.05). During weight control, energy intake was 44.7% of EER in normal WC and 30.5% in high WC group (p<0.05). C:P:F ratio was 69:11.1:19.5, and ratio from protein and fat was lower in the high WC group (p<0.05). Most nutrient intakes during weight control were less than 50% of 2015 KDRIs (RNI or AI), and intakes including thiamin (p<0.01), vitamin A, riboflavin, niacin, folate, calcium, potassium and zinc (p<0.05) were significantly lower in the high WC. Energy intake after weighing before the competition was 1,315 kcal, and energy (kcal/kg BW, p<0.05) and carbohydrate intakes (g/kg BW, p<0.01) were significantly higher in the high WC group. Energy intake between competitions was 691.1 kcal, with no difference by the WC group. Conclusions: Nutrients intakes of combat sport athletes were inadequate. Dietary intakes during weight control were much below than the KDRIs, especially in the high WC group. It is needed to develop nutrition education programs for combat sport athletes to avoid severe energy restrictions and to apply specific dietary guides to each period of training and weight control.

We examine interoperability for integrated training simulation of a mechanized infantry battalion that uses a war game model of Korean army, Combat 21, and virtual simulators of K1 tanks. We discuss issues and problems for integrated simulation of the virtual and constructive models, including differences between the model scopes, model resolutions, engagement algorithms, and data consistency and training audiences of the war game model and virtual simulators. From these, we identify interoperability requirements. We propose ways of resolving the problems using a model converter.

This study focuses on the operating requirements of multi-resolution modeling(MRM) in training war-game model and proposes solutions for major issues of multi-resolution interoperation between Combat21 model and tank multi-purpose simulator(TMPS). We study the operating requirements of MRM through interviews with defense M&S experts and literature surveys and report the various issues that could occur with low-resolution model Combat21 and high-resolution model TMPS linked, for example, when to switch objects, what information to exchange, what format to switch to, and how to match data resolutions. This study also addresses the purpose and concept of training using multi-resolution interoperation, role of each model included in multi-resolution interoperation, and issue of matching damage assessments when interoperated between models with different resolutions. This study will provide the common goals and directions of MRM research to MRM researchers, defense modeling & simulation organizations and practitioners.

The army is carrying out a project of a scientific training system which enables company level mutual training in infantry division to enhance battle command capability and combat skill. In this paper, we tried to prove the necessities of a scientific training system based on previously conducted training results. We drew comparison among proposed alternatives. To obtain the results we used hierarchical analysis methodology And cost and training effectiveness analysis were conducted.

본 연구는 과학과 전투훈련 자료를 분석하여 작전 및 군사훈련 방법을 향상하고 필요한 군사교리를 검증하기 위한 것이다. 우리는 과학화 전투훈련 중 대대급 공격작전에 대해 개별 전투원이 공격작전간 개인 화기를 이용하여 적을 중상 이상의 전투불능 상태로 만든 인원수를 반응변수로 둔다. 본 연구의 반응변수는 영이 지나치게 많이 관측되어 전통적인 일반화 선형모형에서 분석이 제한된다. 우리는 과대산포 및 영이 과도하게 관측된 점을 고려하여 영과잉 회귀모형과 허들 회귀모형을 자료에 적합하여 분석한다. 우리의 분석 결과는 대한민국 육군의 보병대대와 같은 소부대의 다양한 작전 및 전술적 요인에 대한 분석과 전술제대의 군사교리 검증함에 있어 적절한 참고자료로 활용될 수 있다.

Reserved force's training(RFT) is undoubtedly the critical component to increase the national capability in case of emergency. It is because RFT plays an important role in maintaining the peace for the Korean peninsula as the key deterrence force power for more than 40 years. Considering the reserved force reform linked with the goal and the plan of Korean Defense Reform 2020', we can expect the utility of the reserved force as the potential combat power to make national defense resources more efficient and useful. In that sense, this study suggests some solutions to promote the reserved force's competency to demonstrate the ROK Armed Force's combat power as the equivalent partner with the active force as well as the future deterrence power. This study also analyzes the present training system including law and regulation, identifies some implications through the literature review, and designs the future ROK reserved force's training system by extracting new variables forecasting the future environment for national defense. In addition, this study includes its concerned systems generally without limiting the scope into the reserved force. Therefore we try to seek to prepare for mobilization readiness and to promote regional hometown defense capability in order to cope with the enemy's threat in case of emergency.
