NCW which is shaping favorable conditions with obtaining initiative through superiority in C2 and information sharing is critical to the result of the war in a modern warfare. An important requirement to attain superiority through an effective networking in a war-environment is to apply QoS to ensure priority in supporting critical mission and services. In order to obtain an effective NCOE through JCS-led QoS support, standard doucments have been reviewed and analyzed to understand the current level of technology and development. In addition, QoS-related policy documents which is currently being applied by the ROK armed forces have been analyzed to substantiated the JCS-led QoS model and propose the directions of development and enhancement required in the realm of technology, policy and system.

This paper proposes a real-time 3D visualization system for situational awareness of Air force operations. This 3D system of situational awareness supports a high-level commander of Air force during the war game operations. These situation aware supporting data such as the aircraft track data of radar, aircraft schedule database, map and satellite image data are integrated into one structured data and those are visualized as 3D structure. By using an Out-of-Core method, we can visualize a 3D huge data in real-time in mobile notebook environment. The experiment shows several examples of 3D visualization supporting situation awareness for Air force operation.

An unmanned ground vehicle(UGV) today plays a significant role in both civilian and military areas. Predominantly these systems are used to replace humans in hazardous situations. To take unmanned ground vehicles systems to the next level and increase their capabilities and the range of missions they are able to perform in the combat field, new technologies are needed in the area of command and control. For this reason, we present war field simulator based on information fusion technology to efficiently control UGV. In this paper, we present the war field simulator which is made of critical components, that is, simulation controller, virtual image viewer, and remote control device to efficiently control UGV in the future combat fields. In our information fusion technology, improved methods of target detection, recognition, and location are proposed. In addition, time reduction method of target detection is also proposed. In the consequence of the operation test, we expect that our war field simulator based on information fusion technology plays an important role in the future military operation significantly.

Becoming independent in 1956, Sudan has since experienced a number of coups $d^{\prime}{\acute{e}}tat$, religious conflicts between the Islamic north and the Christian south, conflicts between the north-south population composition and races, two civil wars for nearly 40 years due to a clash of interests over resources and others, and the Darfur crisis in which hundreds of thousands died. In 1983, as the Sudanese government forced Islamic laws on the southern region where many Christians lived, the civil war resumed and suffered heavy casualties. Although a brief period of tranquility is maintained at the present moment as South Sudan seceded, military conflicts continue to arise. The objective of this research is to understand the North-South Sudan conflict by examining its history and course. For this purpose, chapter 2 will make a theoretical and reality approach for conflict items and solutions. Chapter 3 will discuss the historical background and reasons for the Sudanese conflict by considering Sudan before 19th century, the Egyptian conquest of Sudan and the diverging North and South, Sudanese independence and other divisions yet again, and finally the North-South conflicts over religion and resources. In Chapter 4, there will be an analysis of the course of the Sudan Civil War by separating it into the First and Second Civil War. In Chapter 5, the consequences and future prospect will be presented in lieu of the conclusion.

In modern war, Intercept Performance of SAM(Surface to Air Missile) is gaining importance as range and precision of Missile and Guided Weapon on information warfare have been improved. An aerial defence system using Surface-to-air Radar and Guided Missile is needed to be built for prediction and defense from threatening aerial attack. When developing SAM, M&S is used to free from a time limit and a space restriction. M&S is widely applied to education, training, and design of newest Weapon System. This study was conducted to develop simulator for evaluation of Intercept Performance of SAM. In this study, architecture of Intercept Performance of SAM analysis simulator for estimation of Intercept Performance of various SAM was suggested and developed. The developed Intercept Performance of SAM analysis simulator was developed by C++ and Direct3D, and through 3D visualization using the Direct3D, it shows procedures of the simulation on a user animation window. Information about design and operation of Fighting model is entered through input window of the simulator, and simulation engine consisted of Object Manager, Operation Manager, and Integrated Manager conducts modeling and simulation automatically using the information, so the simulator gives user feedback in a short time.

This is a study on the dualism of gender through the costume in the Middle Age. Jeanne d'Arc was an existential person in the Hundred Year's war(1338-1453). She persisted in retaining male attire and armour at her own request. One of the points for which she had been condemned was the wearing of male apparel. It was judged as an evil spirit and rendered Jeanne a witch and a heretic therefore she was burned to death in the market place at Rouen, on the 30th May, 1431. It is one of the evidence which represent dualism of gender through the costume.

Railway in Japan has been changed every apr. 20 years as follows, since the war ended in 1945. Shinkansen which was the first high speed train in the world began to revenue service in 1964, and a national railway authority was privatized segmentally in 1987, and after 20 years later from then, the ticketing service using IC card was accomplished. In this research, we review these changes in Japan in the administrative aspects on railway technology, and R & D aspects of the Railway Technical Research Institute, JR East and JR West which are railway corporations. Also we introduce the present status and future of railway technologies in Japan which railway experts diagnosed. In the twenty-first century, the needs of the times for railway have been enormously changed due to a low birth-rate, an aging society, environmental pollution and energy problems and etc. Because we have very similar problems to them like Japan, we could get lessons from Japanese cases in setting the direction for the development of railway technologies.

Drago $Gali{\acute{c}}$ (1907-1992) has been acknowledged as one of most important modern Croatia architects of the 20th century and noted for his controversial apartment buildings at 35-35a and 43-43a blocks on Vukovar Street in Zagreb, Croatia. Although the two housings were highly regarded as the best examples of the post-war housing design in Croatia, a plagiarism controversy arose due to its similar exterior looks to Le Corbusier's $Unit{\acute{e}}$ d'Habitation in Marseille in 1952. This research intends to comparatively analyze architectural features implemented on the works of apartment of Drago $Gali{\acute{c}}$ and Le Corbusier's $Unit{\acute{e}}$ d'Habitation. The analysis focuses on architectural characteristics categorized in three parts: unit plan, community space, and unit combinations. The site survey was carried out to yield more useful information for the analysis. During this process, written and photographic documentations are collected for the further interpretation. In addition, scale drawings are reconstructed for the in-depth analysis of the project.
