It has been almost 10 years since the department of military studies was opened at the civilian universities. One of the important elements for the success of these new departments would be the curriculum. This paper tries to give an realistic answer to the question of curriculum. The factors influencing the design of curriculum of military studies are analyzed, such as the curricular of the military institutes that confer the B.S. in military studies, the domain of military studies and research areas, documentation classification of military studies and military engineering, scientific knowledge versus vocational capabilities in university education, relations between the B.S. courses and the master or doctorate courses, requirements asked by the Army, and moral education needed for the military officers. As a result of the analysis, the mandatory core courses should be total of 19, including 5 general courses and 14 major courses.

Supply units in each command are multi-tiered and each supply unit keeps a supply level independently, which can cause excess stock, leading false reports to the Logistics Command and increasing difficulties in managing user needs. This causes excess assets and the excess then causes deformation in demand. therefore, the supply support systems of our armed forces have become high-cost/low-efficiency and are insufficient to meet the needs of users in combat units. Civilian corporations and the US Department of Defense are downsizing the aforementioned multi-tiered supply systems thus revolutionizing efficient and effective logistics by adopting Supply Chain Management(SCM), and Prime Vendor policies. Prime Vendor policy is a logistics support method that allows users to directly request and receive supply items from suppliers, based on supply contracts between suppliers and central maintenance organizations like KDA. In other words, it is a system that allows for users to make orders to suppliers directly and suppliers to deliver goods to the users directly, cutting out the middle stage, thus allowing an efficient supply. This is a way forward in finance that cuts costs in net supplies and allows an efficient utilization of civilian assets. which is also known to fasten the speed of logistical support and stripping down the logistical structure. therefore, this report will explore Prime Vendor policies adopted in certain number of units for medical supplies that were taken in consideration of improvements in stock management in civilian organizations and the US Army, and aims to apply such policies for repair parts.

In this study, a flat-type photocatalytic reactor is applied under solar irradiation for simultaneous treatment of target pollutants: reduction of Cr(VI) to Cr(III) and oxidation of EDCs (BPA, EE2, E2). An immobilized type of photocatalyst was fabricated to have self-grown nanotubes on its surface in order to overcome limitations of powdery photocatalyst. Moreover, Ti mesh form was chosen as substrate and modified to have both larger surface area and photocatalyst content. Ti mesh was anodized at 50V and $25^{\circ}C$ for 30min in the mixed electrolytes ($NH_4F-H_2O-C_2H_6O_2$) and annealed at $450^{\circ}C$ for 2 hours in ambient oxygen to have anatase structure. Surface characterization was done with SEM and XRD methodologies. Fabricated NTT was applied to water treatment, and coexisting Cr(VI) and organics (EDCs) enhanced each other's reactions by scavenging holes and electrons and thus impeding recombination. Also, several experiments were conducted outdoor under direct sunlight and it was observed that both solar-tracking and applying modified photocatalyst were proven to enhance reaction efficiency.

As a ritual of modern people is getting higher, the safety assessment of the structure related to people has become the most important part in the process of the design. Especially, in the case of a ship, as regulations about the safety of passengers and the pollution in the ocean are strictly reinforcing, the safety assessment has become the most important part in the process of the design. However, because the established safety assessment is mostly depend on the experienced theory, it is so difficult to assess the safety considering a lot of situations such as various ocean environments, the mistake of sailors and emergency situations. As the way to solve this problem, lately the study of the simulation using a computer has been processed. In this paper, we suggested network-based simulation system framework using HLA (High Level Architecture) among many kind of simulations to assess the safety of the ship. Because HLA has already become a standard of the future simulation system in the U.S. DoD(Department of Defense) and Korea army, we expect to raise the possibility in the future. In addition, because HLA makes a standard of documents and a reused component(Federate) of simulation(Federation) by OMT(Object Model Template) and RTI(Runtime Infrastructure), we expect that this study will be developing the safety assessment of ship as well as operation in warship and cooperation with another applications.

The distribution of boundary markers, set up during the Yimjin(1712) Boundary Making and Demarcation(YBMD), has less been addressed so far, although it is key material evidence on which we can reconstruct the whole processes of YBMD, together with the correction of widespread myths around YBMD. This paper aims to clarify the questions on the distribution of boundary markers associated with YBMD, built during August 1712 to September 1713, by reinterpreting the key documents of Actual Survey on them: Huh Ryang and Park Dosang(1913), Kim Woosik(1883), Lee Joongha(1885), Wu Luzhen(1907), Osone Seiji(1907), and Liu Jianfeng(1908), together with topographic maps by Japanese Imperial Army(1933), the report of expedition to Mt. Baekdu by Chungjin Teachers' College(1948), and the report of field survey by Jilin province's expedition(1957). As a result, the distribution of boundary markers built in 1712~1713 is successfully reconstructed, and summarized in the format of table and maps.

This paper researched the operation methods of software video teleconferencing on the tactical communication networks under 1Mbps. The tactical communication networks have limited bandwidths, frequent data losses and transmission delays due to the unstable networks. In addition, the bandwidth for video teleconferencing has to be much smaller since the Army Tactical Command Information System(ATCIS) has priority of using the bandwidth. This paper analyzed such restrictions of tactical communication networks, presented some methods to improve the quality of the software video teleconferencing on the tactical communication networks and their actual experiments as well. It is applied in the first place to re-transmit the lost packets and to reduce the image size for the data traffic. Nothing is better for the video teleconferencing than to provide the bandwidth enough for every user. However, on the tactical communication networks with the limited bandwidth, video teleconferencing can be improved by optimizing the compression rate of image data, the number of image frames, the audio codec and the usage of audio compensation data.

This study conducted research over status of employment and living by collecting questions & answers from retired soldiers after service in ROK Army more than 5 years in last 5 years. As the methodology of this research, the status of employment has been provided from the Citizen Insurance Public Corporation, and conducted interviews for all individuals in addition to the receiving of questions & answers. Also, the statistic data prepared and submitted for Congressional Audit & Inspection from MND was also utilized for the purpose of research. In conclusion, the situation faced with retired soldiers after their retirement is showing the future of reflection of oneself to the personnel in active service who must do their best only for their duty to keep national security. If those personnel in active service are worrying about their future returning to civilian society after retirement, it will not only become an impediment to perform their duty but also bring invisible weakening of military power to defend our nation in result. This is the rationale for the necessity of providing support for social adaptation, reemployment and inauguration of retired soldiers.

The main theme of this study is about North Korea's contemporary military strategy which remained a blind spot in the 21st century. Indeed, Pyongyang's contemporary military strategy is evolved from the logic of War. On the basis of this logic, this study examined North Korea's contemporary military strategy with three analytical frameworks. The first is the discovery of Clausewitz's dictums and application of the Trinitarian analysis on the Korean cases. During the course of applying Clausewitzian main dictum--War as continuation of politics, the methodological analysis on war played a important role generalizing the pattern and matrix of North Korea's strategic thinking and military strategy. In particular, Clausewitz's Trinitarian framework on war -Government (reason), Army (chance), People (passion)- was a universal framework to scrutinize the North Korean missile and nuclear strategy. The second is about the matrix of North Korea's military strategy, The study suggested the genealogical feature of Pyongyang's military strategy. In principle, the dictum of 'Military-First Politics' 1S the combination of the political philosophy, Chuch'e (self-reliance) of Kim Il Sung and Kin Jong Il reflected in the military readiness. As a result this analysis was able to equate Clausewitz's dictums to explain Pyongyang's idea of the nature of war in that North Korea's military strategy is the central instrument of delivery to achieve political objectives. The third is about the theoretical encounter of 'Clausewitz's Wonderful Trinity' and 'Remarkable Trinity on North Korea's contemporary strategy'. On the basis, three elements are connected to one of three groups in society; the people, the military, and the government. In order to apply the Clausewitz's Trinitarian analysis into Kim Jong Il's 'Military-First' strategy, two case studies (Missile and Nuclear strategy) were examined. The finding of this study is that Clausewitzian dictum in the 19th century is still valid in the 21st century as it provided plausible theoretical framework to explain the North Korean contemporary military strategy with a reminder that the nature and logic of war are fixed in the socially constructed state.

Conservation of the natural environiment In chosun-Dynasty, Korea, is analysed on the basis of the of official records of the king's offices(Chosun-wangjo-sillok). In the popular ideologies of the dynasty, Seongleehak(philosophy of humanity arid natural laws) and Pungsu (geomancy) , the naturnal enviroment is defined as an entity con-sisting of Cheon (heaven) , San(mnountains) , Su (water), Geumsu (animals)and Chomok (plants) .the notion of Tacksi-Tackmul(being careful to take natural resources at the right time) was one of the Cheonmyung (eavenly decrees) . It was believed that violation of this principle resulted in natural disasters. Sasan(four mountains surrounding Hansungbu-, the capital city, now Seoul) , were strictly preserved according to geomancy practices. In areas other than the capital city, Sanlimcheontack (mountains, forests, rivers and ponds) were con-served for sustained production of building materials especially pinetrees for ship building, foods, firewoods, horses, and orter useful natural resources. Various conservation policy insturuments were adopted. Prunning trees was permitted only in October. Capturing fishes was allowed only after the spawning period. Protection areas were designated in Sasan, Seongjoesiplee (surroundings of the capital city) , Geumsan(protected mountains), Kangmujang(hunting and army training grounds), Sijang(firewood areas), Mokmajang(horse ranches) and Neungyuk(royal tombs) . Activities prohibited for conservation purposes included cutting timbers, burning, building houses or tombs, dumping wastes, farming and breaking up fresh land, grazing, hunting and trespassing. Positive actions for conservation were rituals to Heaven ennoblement of natural elements such as mountians or rivers, planting trees, Boto (supplementing soil on low ridges) , Josan (mounding) and making ponds. Boto, Josan and making ponds were to make ideal terrains for geomancy. Many government bodies and civil servants were engaged in the conservation activities. For example, Sanjik(forest keeper) was a special position with responsibility for forest management.

Several numerical models for predicting beach profile changes have been developed by many researchers. Many of the earlier models are known to simulate the erosional profiles with the formation of offshore bar. However, most of the models don't have proper mechanism to incorporate the recovery process of the eroded profiles after a storm and can not simulate the beach accretion with acceptable accuracy. In order to overcome these shortcomings, we propose a new numerical model which has new features to simulate the accretional phase of beach recovery process after storm including such as redistribution of suspended sand particles near the breaking point. The simulation results of the proposed model were compared with LWT (Large Wave Tank) experiments performed at CRIEPI (Central Research Institute of Electric Power Industry in Japan) and CE (the Us Army Corps of Engineers) and it was shown to have performed better compared to SBEACH (Storm-induced BEAch CHange).
