Dr. George Schimert, born in 1918 in Switzerland, received his medical degrees from universities in Hungary and in Germany. After immigration to the United States, he continued medical training at several hospitals. In 1956, for pursuit of cardiac surgery, he had joined the group headed by Dr. Walt Lillehei at the University of Minnesota. During this period, in 1958, he joined Seoul National University Hospital as a overall medical adviser and adviser in surgery for 15 months in partnership with the University of Minnesota Medical School. During his stay in Korea, in addition to the works in the medical administration and education, he contributed to the early establishment of thoracic surgery program. In August 6, 1959, he performed open heart surgery using cardiopulmonary bypass for an ASD patient at Seoul National University Hospital. However, the patient died 6 hours after the operation. In 1960, after returning to the United States, he began his career at Buffalo General Hospital as the first director of its cardiac surgery program. In 1985, the Dr. George Schimert Lectureship and Medical Conference was established to honor his contributions and achievements. He died December 7, 2002.

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.

In this paper, we propose unmanned vehicle based tracking network (UVTN) architecture and algorithms which employ multiple autonomous unmanned ground vehicles (AUGV) to efficiently follow targets in a group. The goal of UVTN is to maximize the service coverage while tracking target nodes for monitoring or providing the network access. In order to achieve this goal, UVTN performs periodic expansion and contraction which results in optimized redistribution of AUGV's in the network. Also, enhanced algorithms such as fast contraction and longest first are also discussed to improve the performance of UVTN in terms of the average coverage ratio and traveled distance. Simulation results show that the proposed UVTN and enhanced algorithms can effectively track the moving target and provide the consistent coverage.

There has been skeptical aspects for the robot to be effective in combat fields even though consensus of operational needs and some technological advancements. One of fundamental problems is difficulties in the autonomous technology applicable. This technology is not sufficient to be applied for heavy combat operation, therefore, developer first make open architecture, then, application is implemented on the condition that new functions or technologies will be developed later. It is also required to partition all the functions with common segments which are general to all platforms in order to operate together in the fields and to reduce the load of development to each platform respectively. In addition, common middleware based on the reference architecture is also developed to accommodate new technology evolution. This paper introduces the architecture and middleware applied in XAV(eXperimental Autonomous Vehicle) developed in ADD. In addition, the performance of autonomous navigation and system design characteristics are introduced briefly.

The purpose of this study is to examine the satisfaction level for military food services as well as to find out influential factors which affect satisfaction. The questionnaire survey was conducted by 111 soldiers. In the satisfaction analysis for military food services, 69.3% of soldiers presented positive response. There are, however, some differences in satisfaction between corporal and private groups as well as corporal and sergeant groups. Overall, the corporal group shows low satisfaction for military food services. To identify influential factors for satisfaction of military food services, we considered various factors: tasty, nutrition, quantity, hygienic conditions, environment, ambient factors, waiting time, presence of desert, menu, and kindness of a cook. Satisfaction analysis shows that main significant factors are tasty and quantity of the food. Thus, tasty and quantity of the food are need to be consistently monitored and improved to increase the satisfaction of military food services.

Rearing of Spodoptera litura fed on arfificial diet basically formulated with kindby bean powder was much promisible for production of S. litura nuclear polyhedrosis virus(SINPV) than that on kidney bean leaves. The $LC_{50}$ of SINPV against 3rd and 5th instar were $4.48{\times}10^{3}$ PIB/ml and $4.52{\times}10^{4}$ PIB/ml, respectively. The $LC_{50}${/TEX} of SINPV varied from 5.8 days to 7.7 days at higher inocula in the testes. The larval growth of 1st and 3rd instar larvae fed on virus were much delayed and the larval were killed within 4th instar in the former and within 5th instar in latter. S. litura larvae were very susceptible to multinucleocapsid nuclear polyhedsosis virus (MNPV) of Autographa californica, S. littoralis and Trichoplusia ni.

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.

The purpose of this paper is to develop curriculum for the Department of Computer Application Based Army Contracts. Because the Army contract department is a retraining undergraduate degree program targeting noncommissioned officers in service, its curriculum has no choice but to differ from those of other departments. The curriculum of the Department of Computer Application focuses on the reeducation of noncommissioned officers in service and consumers of education. In addition to the subjects related to the scientific and informational movement of the military, the subjects needed to qualify for the second-degree military counsellor certificate are reflected in the curriculum, which is a first for regular universities. The appropriate curriculum of the Department of Computer Application will be proposed including subjects for noncommissioned officers to cultivate leadership skills for managing subordinates and various subjects road map of department specializations will be also developed.

In network-centric warfare, the communication network has played a significant role in defeating an enemy. Especially, the urgent and important data should be preferentially delivered in time. Thus, we proposed a priority MAC protocol based on CSMA/CA with Binary Exponential Back-off for tactical wireless networks. This MAC protocol suggested a PCW(Prioritized Contention Window) with differentiated back-off time by priority and a RBR(Repetitive Back-off Reset) to reset the remaining back-off time. The results showed that this proposed MAC has higher performance than those of DCF(Distributed Coordination Function) in the transmission success rate and the number of control packet transmission by reducing the packet collision. Thus, it produced more effective power consumption. In comparison with DCF, this proposed protocol is more suitable in high-traffic network.
