Objective : The purpose of this study was to investigate prevalence of psychiatric symptoms and determine predictors of emotional distress of military hospital surgical patients. Methods : This study examined 104 orthopedic patients admitted to the Armed Forces Military Hospital September-November 2018. For the study, every subject completed self-assessment inventories regarding depressive and anxiety symptoms (Hospital Anxiety and Depression Scale), sleep problems (Pittsburgh Sleep Quality Index), problematic alcohol and tobacco use (Cut off, Annoyed, Guilty, Eye-opener screening), and psychiatric history. We performed the Student's t-test and the chi-square test for the collected data to investigate the prevalence of psychiatric symptoms, including emotional distress. Logistic regression analysis was used to examine the risk factors related to emotional distress of hospitalized military personnel. Results : There were no significant differences in socio-demographic and psychiatric symptoms between soldiers and officers. The prevalence of depressive and/or anxiety symptoms (emotional distress) was 21.2% (n=21). In the logistic regression analysis, psychiatric history [Adjusted Odds Ratio (AOR)=18.99 ; 95% Confidence Interval (CI)=1.42-253.57 ; p=0.026] and low military life satisfaction (AOR=15.67; 95% CI=1.46-168.11 ; p=0.023) correlated with emotional distress. Conclusion : Soldiers admitted to the military hospital showed similar prevalence of emotional distress as those at general hospitals. Considering military circumstances, it is necessary to detect and intervene regarding soldiers with a psychiatric history and low military life satisfaction to promote mental health at military hospitals.

The key lessons of the very complex modern war can be dangerously misleading to the outsiders. The efforts trying to draw lessons learned from the Iraq War (OIF : Operation Iraqi Freedom) may be biased by the view of point by Americans, because most of war episodes have been come from the Western media coverage. More serious bias can be committed thanks to the differences of warfighting doctrines and military technology between US forces and ROK forces. However, OIF-fought allied commanders and outside military experts said this campaign exemplified 21st-century warfare: swift, agile and decisive, employing overpowering technology to bring relentless violence to bear in many places at once. Even though the campaign evolved differently than anticipated, allied forces regrouped and regained the initiative remarkably quickly, thanks in large part to a new command flexibility, tied to new technology that made possible the more rapid sharing of data. These factors permitted "new air-land dynamic". The things that compel that are good sensors networked with good intelligence disseminated through a robust networking system, which then yields speed. Speed turns out to be a very important factor for conducting "Rapid Decisive Operations" relied on joint "Mass of Effects". ROK forces facing the heaviest ground threat in the world may learn more from Cold War era-typed US Army 3rd Infantry Division (3ID), which operating considerably beyond existing doctrine. 3ID flew its personnel into Kuwait to meet up with equipment already located in the region as pre-positioned stock. During OIF, the division conducted continuous offensive operations over 230km deep battlespace for 21 days. The lessons learned for ROK army to prepare tomorrow's war may be found from 3ID in its training, command and control, task organization, firepower and battlespace management, and logistics.

Purpose: The purpose of this study was to evaluate a cognitive behavioral anger management intervention in order to increase self-consciousness and decrease anger among Korean military men, Methods: A quasi-experimental design was used for this study. Ninety two soldiers were screened for unhealthy anger expression using a questionnaire. Among them, 26 soldiers who showed unhealthy anger expression were selected for this study. They were matched by rank and assigned to either a treatment or control group. The treatment group received the intervention three consecutive times, once a week and for 120 minutes per session. Participants were assessed before and after the intervention for anger (the State-Trait Anger Scale) and self-consciousness (Self-consciousness Scale). Data was analyzed using descriptive statistics, $x^2-test$, Mann-Whitney test, and Wilcox on signed rank test. Results: There was no statistically significant decrease in anger or increase in self-consciousness between the two groups following treatment. However, there was a significant increase in private self-consciousness in the treatment group after the intervention(p=.006). Conclusion: The cognitive behavioral anger management program improves private self-consciousness in soldiers. However, Additional research is needed to explore whether long-term intervention is more effective for anger control in the military setting. The findings from this study suggest that more attention should be given to mental health care for Korean soldiers.

Objectives: The purpose of this study was to establish a relationship among oral health perception, practicality, and the health-promoting lifestyle profile (HPLP) of soldiers, to finalize the oral health education content to be offered to military personnel under military service and explore remedial measures. Methods: The subjects included military soldiers older than 19 years of age in the Chungnam province. The study instrument was a structured questionnaire evaluating the general characteristics, HPLP, oral health perception, and oral health practice. Data were analyzed using one way analysis of variance (ANOVA), Kruskal-Wallis ANOVA, Pearson correlation, and multiple regression analysis. Results: The HPLP evaluation of the soldiers was 3.39, and the group with the higher HPLP level showed better oral health recognition and oral health practice, with a statistically significant difference. There were differences in oral health perception, tooth brushing practice, and oral health education interest depending on the level of education and stratum of the soldier. The higher the soldier's HPLP, the higher were the oral health perception and oral health practice. The factors affecting the HPLP were oral health perception, tooth brushing practice, and interest in oral health education. Conclusions: After the military discharge, it is necessary to devise ways that will enhance oral health perception and practices that promote good oral health and lifestyle.

In this paper, we propose a novel behavioral model that explains the use of the military battlefield management system more effectively in the non-voluntary use environment. This study intends to suggest a model based on the Unified Theory of Acceptance and Use of Technology(UTAUT), an extended TAM. Also, it introduces the concept of 'Conative IS use' as a dependent variable that can explain user's behavior more effectively in non-voluntary technology acceptance environment. In addition, we propose the major factors affecting the UTAUT components from the TOE(Technology-Organization-Environment) perspectives, and analyze their effects. In order to validate the proposed model, this study applies PLS(Partial Least Squares) to the survey collected from military personnel. The findings of our study may shed a light on improving the effectiveness of battlefield management information system.

The Army, Navy, and Air Force are currently making various efforts to apply defense IoT technology by reflecting the characteristics of each military. However, there are concerns that comprehensive collection, management, and analysis may be limited because each military has no overlapping system or guaranteed interoperability of data, and there are inefficient aspects in terms of using and investing a limited defense budget. In this study, evaluation items and priorities for pilot projects were selected by applying Delphi technique and AHP method to determine which projects are preferentially effective when commonly applied in terms of Army, Navy, and Air force. As a result of the analysis, the project basis and driving force, project feasibility, performance and ripple effect, redundancy and connection were identified in the order of IoT-based small detachment units and unmanned base construction, intelligent smart unit, smart ground ammunition depot, and smart training management system. According to the comprehensive results reflecting the weights of each evaluation item, the fact that small detachment units and unmanned base construction project are recognized as the first project to be applied to the Army, Navy, and Air Force is a valid approach to be effective while each military is burdened with personnel management because of the reduction of manpower. Through the research results, it is expected that the direction of application to the policy of the defense IoT project can be confirmed in terms of efficient use of limited budgets.

This paper reviewed the awareness of the military personnel as to job training executed in the Korean army and to figure out how this job training affects the military morale and organizational performance. For this study, 220 volunteers were surveyed and analyzed using the SPSS statistical package program. As a result of the analysis, the following conclusion could be drawn. First, in the result of analysis on the status of-the-job education, the educational time marked 49.5% for 2-4 hours, the education of job capability development marked 77.7% for the content of education, and the charged instructor of job training marked 56.8% for the education department. Second, in the result of an analysis of job training on military morale, the recognition level of behavioral dimension increased with increasing participants' independence, and the satisfaction with the cognitive dimension increased with increasing participants' independence, continuous learning culture, and educational level. Moreover, the emotional score increased with increasing learning culture and educational level. Third, an analysis of the influences of job training on the organizational performance showed thatthe degree of job satisfaction increased with increasing learning motive and learning culture, and the organizational commitment increased with increasing instructor's quality. Fourth, regarding the influences of military morale upon the organizational performance, the higher job satisfaction and organizational commitment increased with increasing behavioral, cognitive, and emotional dimension. Therefore, military morale improves organizational performance and is an important factor in inducing individual development.

Early generations of products had little to no inherent capability to test themselves. The technologies involved often required only visual inspection and limited probing to troubleshoot the system once it was turned over to maintenance personnel. However, as the complexity of military and commercial systems grew, symptoms of failure became less noticeable to the operator. Therefore, the procedure to access, inspect, repair and replace a component became complicated, the requirements for personnel skill and testing equipment increased. and it took too long of a time to maintain a system. Meanwhile, the need for availability became more mission-critical and maintenance become very expensive. The obvious solution was to design in-system circuits or devices to self-test the primary system, the Built-In-Test(BIT) was born. This approach has continued right on up through present systems and is an integral part of systems now being designed. The object of this paper is to present a state-of-the-art research for filtering out the BIT diagnosis mistakes using Bayesian analysis and develop the algorithm for Redundant systems with BIT to improve BIT diagnosis.

Wargame is a simulated military operation with certain rules, specifications, and procedures, in which soldiers can virtually and indirectly experience the war. The ROK Navy operates the Cheonghae model, a training wargame model for helping commanders and staff master the procedures for conducting the war. It is important for commanders, staff and analysts to know whether a warship can perform its missions and how long it can last during a war. In existing model, the Cheonghae, the probability of kill of a warship is calculated simply considering the number of tonnage without any stochastic elements, and the warship's mission availability is also determined based on predetermined values. With this model, it is difficult to get a value of the probability of kill that makes sense. In this dissertation, the author has developed a probabilistic model in which the warship vulnerability data of ROK-JMEM can be used. A conceptual model and methodology that can evaluate the mission performance of personnel, equipment, and supplies has been proposed. This can be expanded to a comprehensive assessment of wartime warship loss rates by integrating damage rates for personnel, equipment, and supplies in wartime.
