Problem Based Learning(PBL) is one of effective teaching-learning strategy for enhancing military students' motivation, comparing with the other study method. After monitoring military student classes, we conclude that PBL can enhance the effectiveness of learning in War history case study education and finds merits; PBL assists students to play a more active role in the class, induces students to solve problems independently, and makes the learning military situation real case study. The case study is common in social sciences and life sciences. Case studies may be descriptive or explanatory. It is good for War history education. The demerit of PBL is a costly method as students should spend more time and institutions should provide more manpower and materials. This study suggests that more empirical researches on alternative teaching methods, including PBL, to a lecture in War history education.

Objective : Previous studies reported a correlation between the low serum cholesterol level and impulsive behaviors. In this study, we investigate an association between the serum lipid levels and psychological parameters in maladaptive soldiers in the Korean Army. Methods : A total of ninety-six maladaptive subjects and thirty-six normal controls in the Korean army were evaluated with the Korean version of Barratt Impulsiveness Scale (K-BIS), Korean version of Beck Suicidal Ideation Scale (K- BSIS), Korean version of Beck Depression Inventory (K-BDI) and Korean version of Beck Anxiety Inventory (K-BAI). Serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL) level were measured by overnight fasting blood sampling. Results : There were no significant differences between the groups in demographic characteristics. Serum total cholesterol levels (t=-2.209, p=0.032), triglyceride levels (t=-4.593, p<0.001), and LDL levels (t=-3.753, p=0.001) of maladaptive subjects were significantly lower than those of normal controls, and maladaptive subjects had higher K-BIS scores than normal controls (t=7.542, p<0.001). Negative correlation was found between LDL levels and non-planning impulsiveness in the maladaptive subjects (r=-0.253, p=0.013). LDL levels (${\beta}=-0.258$, p=0.008) and K-BDI scores (${\beta}=0.266$, p=0.043) emerged as significant predictors for non-planning impulsiveness. Conclusion : These results suggested that LDL level was associated with non-planning impulsiveness. These findings suggested that serum cholesterol levels might be available as a biological marker of impulsiveness. However, more large samples, longitudinal biological study and psychiatric evaluations should be needed to develop a preventive intervention for maladaptive male conscripts in the Korean army.

This article aimed at change patterns of representations of male character and cinematic space in 2000s korean division films. The concept of division film is the unique particularity film in the narrative and representation about Korean division. The Gancheop is the special character of korean films and have been reproduced in a variety of ways. In the past, Korean films have been dealt with Korean Civil War and 'special nature' of inter-korean ties. But in the 2000s, the representation of Gancheop in films has begun to change and filmed in a variety of genres such like comedy, thriller, romance and so on. , , are consistent with close relationship of male characters. The relationship is represented as friend, brother, partner. The meaning of these changes symbolizes our concept of national unification.

The purpose of this study was to investigate the perception of Air Force human resources (Civilian defense manpower, Officer, Noncommissioned officer, Solder) for the radiation perception. The subjects were 259 men and women who visited at the Aerospace Medical Center. As for the method, a survey study was conducted using a questionnaire with a total of 14 questions about radiation perception (risk, benefit, management). For statistical analysis, an independent sample T-test and one-way analysis of variance (ANOVA) were used to compare the average of confirm a significant difference among groups. The correlations between variables were tested with Pearson and Spearman correlation coefficients. As a result, in the air force human resources, perception of radiation risk of females had a significantly higher awareness than male. Radiation benefits had a significantly higher awareness among married people, military officers, officers, and non-commissioned officers. Radiation control was significantly higher in men, married men, and those with more than 16 years of military experience.

The purpose of this study is to investigate the effects of closed-type SNS use (i.e., Naver Band) on the perception and behavior of the Korean Army soldiers. In contrast to open-type SNS (e.g., Facebook or Twitter), Naver Band is an online communication service system mostly based on confined offline social network. Therefore, it increases communication between acquaintances who have previously formed relationships. Although the Korean Army recently began to use Naver Band as a method of communication between soldiers, their parents/acquaintance, and Army commanders (or leaders), little research has been done about how this use directly affects army soldiers. Hence, applying the motivation opportunity ability theory of behavior, this study examines how enjoyment (Motivational factor), social ties (Opportunity factor), and social intelligence (Ability factor) affect soldiers' belongingness to their organization and organizational citizenship behavior (OCB). We also hypothesize that army soldiers' belongingness and OCB may enhance their individual performance. Survey results show that enjoyment, social ties, and social intelligence increase army soldiers' belongingness, which leads to OCB. Also, enhanced OCB increases individual performance. However, the effect of enjoyment and social ties on soldiers' OCB is non-significant and soldiers' belongingness does not have influence on individual performance. Theoretical and practical implications are presented.

Objectives The aim of this study was to find out the psychological changes associated with internet addiction between before and after the military drill among the young male army recruits. Methods All 1091 participants were army recruits aged from 19 to 22 years who participated in the 5-week military drill. They were assessed with some self-reported questionnaires [Sociodemographic questionnaires, Young's Internet Addiction Scale (IAS), the State-Trait Anxiety Inventory (STAI), the Beck Depression Inventory (BDI), the Barratt Impulsiveness Scale (BIS), the Attention-Deficit/Hyperactivity Disorder Self-Rated Scale (ASRS)]. They were divided into two groups, One is the internet addiction tendency group and the other is non-addiction group according to the IAS score. And the severity of the internet addiction tendency, depression, anxiety and impulsiveness were evaluated by the IAS, the STAI, the BDI, the BIS, the ASRS before and after military drill. Results The result of the paired t-test shows that the IAS, the STAI, the BDI, the BIS, the ASRS scores decreased after military drill in both non-addiction group and internet addiction tendency group. The result of the repeated measures ANOVA shows that there is an interaction effect between the changes of ASRS-hyperactivity (F = 23.437, p < 0.001), ASRS-impulsiveness (F = 4.896, p = 0.027), BIS-total (F = 4.057, p = 0.044), BIS-motor impulsiveness (F = 13.609, p < 0.001) scores and groups. The result of the generalized estimating equation shows that internet addiction tendency is associated with ASRS-inattention (${\beta}=0.075$, p < 0.001), ASRS-hyperactivity (${\beta}=0.092$, p = 0.002), STAI-trait anxiety (${\beta}=0.046$, p < 0.001), BIS-motor impulsiveness (${\beta}=0.119$, p = 0.028). Conclusions The results show that psychopathologies such as internet addiction tendency, depression, anxiety, impulsiveness may improve after military drill regardless of the groups. Internet addiction tendency may be related to the ASRS-inattention, ASRS-hyperactivity, STAI-trait anxiety, motor-impulsiveness. So these findings may be considered in the treatment of internet addiction in terms of the impulsiveness control.

In the early days of the Goryeo Dynasty, the royal guard was comprised of the central regular army in the 2-gun-6-wi system, and Nasungeomgun was in charge of the security inside the palace. However, the military system became disorganized during the period of military rule and the royal guard had to rely on military subjects. The military officials suppressed the civil ministers centering on Jungbang, the guarding organization close to the King to incapacitate the royal authority and control the state affairs. When the rule of the three leaders of the military rule became short-lived and Dae-seung Gyeong is raised to the ruler, he organized a do-or-die squad comprised of a hundred and more people for his personal safety, and this became the first dobang. Dobang was disassembled after Dae-seung Gyeong died of disease, but under the rule of Chung-heon Choe, Dae-seung Gyeong's dobang was revived and reinforced into 'Yukbeon Dobang' to provide the ruler with personal protection and intensify the ruling system, and it was quite a large organization with more refined system. Yukbeon Dobang was expanded and reinforced into Naeoedobang under the rule of Woo Choe, the son of Chung-heon Choe, and it was enhanced even more into Dobang Samsipyukbeon System under the rule of the grandson, Hang Choe. Dobang can be considered as the guard organization in modern sense, and it collected information and surveyed the area where guarding is required and house troops that belonged to Naedobang eliminated the risks that may follow afterwards to make assurance doubly sure for guarding. The Choe's regime established Mabyeolcho as a private guard organization in addition to dobang, and this formed the cavalry and infantry units with dobang. Yabyeolcho organized by Woo Choe in the reign of King Gojong was divided into Joabyeolcho and Ubyeolcho, and later Sineuigun was integrated with them to form Sambyeolcho. Originally, Yabyeolcho was established under the rule of Woo Choe to prevent crime in the evening, but after Sineuigun was organized with the ones who were captured by Mongolian army but escaped, in other words when Sambyeolcho was organized, the organization displayed much broader influence by covering military and police affairs as well as punishment and imprisonment. The guarding organization during the Period of Military Rule in the Goryeo Dynasty did not have strict distinction between official guard and personal guard. The private guard in modern days which is the equivalent of personal guard is characterized by its commerciality, however, house troops and the members of dobang did not seem to pursued profit. The guard organization during the period of military rule started from dobang which was organized for personal safety but gradually developed publicness through the participation of civil ministers and expansion, and later it played the pivotal role for social security serving official purpose up to the level where the distinction between official and private activities was blurred during the period of Sambyeolcho.

Objectives : The purpose of this study was to examine cognitive and psychological characteristics of patients who visited psychiatric outpatient clinic with military service suitability issues. Methods : Since January, 2017 to September, 2018, patients were recruited from the department of psychiatry of university hospital. Participants were diagnosed using DSM-5 criteria by board certified psychiatrists. And each of participants tested with K-WAIS-IV, K-SCL-95 by clinical psychologist. The data were analyzed using SPSS 18.0. Results : The results indicated 24.6% of the patients have significantly low level of intellectual functioning. and 10.8% of the patients have borderline level of intellectual functioning, and 26.3% of them were below average. The results of psychological characteristics showed patients have cautious and potentially dangerous level of depression, anxiety, agoraphobia, and suicidal idea. And PTSD subscale's mean score was above problematic level. Next, we divided patients into two groups based on question of whether the patient is eligible to serve in the military service or not arises from recruitment process or army training center. But two group didn't differ significantly. And for further analyses, we also divided patients into two groups based on if they got single psychiatric diagnosis or more than one psychiatric diagnosis. Conclusions : The results indicated that group which has coexisting psychiatric disorders were more depressed, had higher level of anger and aggression, and had more serious levels of suicidal ideas than single psychiatric diagnosis group. The implications and limitations were discussed along with some suggestions for the future studies.

Since a soldier manages a hand-held landmine detector by hands, it is necessary to develop a system that can detect the target quickly and accurately. However, the hand-held landmine detector used in Korea has a problem that it can only detect the metal mines. Therefore, it is important to solve the problem and to develop a hand-held landmine detection system suitable for the Korean environment. In this paper, we propose a hand-held landmine detection system suitable for the Korean environment using ground penetrating radar. The proposed system uses depth compensation, matched filtering, and frequency shifting filtering for preprocessing. Then, in the detection step, the system detects the target using the edge ratio. In order to evaluate the proposed system, we buried landmines in sandy loam which is most of the soil in Korea and obtained a set of ground penetrating radar data by using a hand-held landmine detector. By using the obtained data, we carried out some experiments on the size and position of the patch and the shifting frequency to find the optimal parameter values and measured the detection performance using the optimized values. Experimental results show that the proposed preprocessing algorithms are suitable for detecting all landmines at low false alarm rate and the performance of the proposed system is superior to that of previous works.

This study was conducted to develop a group counseling program to solve the problem of maladjustment of military personnel and to verify the effectiveness of the program. The 12 session CBT and ACT program for military soldiers experiencing emotional and behavioral problems was developed and the effectiveness was verified by conducting a program once a week for soldiers in the army units based in South Chungcheong Province. Adult Self Report scale(ASR) was implemented for pre-post test and analysis, and descriptive statistical analysis, cross-analysis, paired sample t-test, and independent sample t-test were performed to analyze the results. The results indicated are as follows: First, the preliminary homogeneity test between groups showed that the two groups had homogeneous demographic characteristics and the characteristics of the variables. Second, as a result of the pre-post test verification, both CBT and ACT groups showed significant changes in problem behavior totals, internalizations, and externalizations. Third, there was no difference between the pre-post-examination of the CBT group and the ACT group. This study is meaningful in that it was involved in the maladjustment problem within the military unit, and compared the effectiveness between the two theories, and proposed the study of control groups and further studies on more diverse and diverse subjects that were not implemented under the circumstances of the unit.
