  • 본 논문은 사이버 작전 상황을 직관적으로 이해하기 위한 사이버 군대부호를 제안한다. 현재 사용하고 있는 군대부호들은 사이버 작전을 고려하지 않고 물리적 작전만을 고려하여 표준화되었다. 미군의 합동군대부호 표준인 MIL-STD-25 25D에서는 일부 사이버 작전을 위한 부호들이 포함되어 있으나 영문자 3자로 구성된 아이콘만이 표준화되어 있다. 따라서 사이버 작전을 효과적으로 표현하는데 한계가 있다. 이러한 이유로 본 논문은 현존하는 군대부호 생성 규칙에 부합하는 사이버 작전을 위한 군대 부호를 제안한다. 단지 군대부호만을 제시하는 것에 그치지 않고 제안하는 부호의 효용성을 증명하기 위해 제안하는 부호를 사용하여 다양한 사이버 상황을 표현한 예제도 함께 제시한다. 본 논문에서 제안한 부호들이 모든 사이버 상활을 표현할 수는 없으나, 제안한 부호들을 기반으로 더 많은 부호들이 향후 표준화될 수 있을 것으로 기대한다.

  • In this paper, we propose a channel allocation algorithm of MSAP(Mobile Subscriber Access Point) and data delivery scheme exploiting the symbol level network coding. The network is comprised of TS(Tactical Switch) as a backbone node, MSAPs, and TMFTs(Tactical Multi-Function Terminal). The TS performs the channel allocation considering the communication range overlapping between the neighboring MSAPs and applies the symbol level network coding, if necessary, depending on the position of the TMFTs. Assuming the number of available antennas of TMFT and MSAP will be extended to two from one, we propose two schemes: single mode and dual mode. Through the simulation, we show that the proposed delivery scheme provides higher delivery ratio and lower delivery delay compared with the legacy store-and-forward scheme.

  • This paper is about the implementation of the OFDM-based border guard/reconnaissance communication terminal systems. We have implemented Real-time Dynamic DL/UL symbol rate control function using the DL-MAP message, and proposed error detection method caused by malfunctioning and timing optimization method. The proposed scheme detects the variable rate symbol decoding timing without increasing additional physical layer logic, and also provides a wide variety of DL/UL data transfer rate. Furthermore, the proposed scheme applies to the current border guard/reconnaissance equipment and confirms a operation performance through field tests and demonstration at home and abroad.

  • The object of this research is to inform readers of the chronikal change of Military Uniform in wars how the features and colors of uniforms have been changed along with the innovations of firearms. Military uniforms can be put into two differ-ent categories which are 'Battle wear' and 'Rank wear' A battle wear features of protec-tion and user fiendliness, These features of a battle wear can possibly minimize injuries and help increase the level of battling perform-ance. On the other hand a rank wear help dis-tinguish soldiers from their ranks and posi-tions. A rank wear symbolizs the pride that soldiers take n their unit and by wearing a rank wear soldiers feel more attached to their collegues and unit. Concrete process of military uniforms is as follows. 1. As firearms were innovated corres-pondant innovation of military uniforms were also needed this innovation were in the formstructure design color etc. 2. In the beginning features of military uniforms changed toward protection and then after social status of solders rised features changed forward show-off Finally as firearms became more fortal camouflage became the most significant feature of the military uniforms. 3. During war colors of military uniforms tended to be a means of show -off and camou- flage and while not in war they functioned as symbol which represent froops and the unit is tradition. 4. Other accessaries support the perforance and the symbolical function of uniforms.

  • In this paper, we analyze the performance of Follower Noise Jamming(FNJ) considering three practical tracking parameters such as tracking bandwidth, tracking time and tracking success probability. The performance of FNJ is compared with that of Partial-Band Noise Jamming(PBNJ) in terms of Symbol Error Rate(SER) at the communication receiver under the assumed typical operation model. It is observed that the performance of FNJ is non-linearly dependent on the tracking bandwidth, the tracking time and the tracking success probability. As we can easily expect, it is also observed that the performance of FNJ is better than that of the PBNJ. Finally, it is shown that, for a fixed tracking bandwidth, the combinations of the required tracking time and the tracking success probability which satisfy a certain required SER.

  • The costume originated from the idea that it could protect human beings from ferocious beasts. The military costume was from protection against an enemy equipped with weapons. Furthermore, the makers of the costume were afraid of supernatural powers and it made them devise an armour and decorate it by the concept of superstition for the purpose of overcoming it. The function of military uniform was important for increasing the protection against any enemies while they join in battle. However in harmonious time, it represented artwork of peace, dignity, and order. Since the uniform was a king of symbol to show their position, and their role. They could feel proud as a member of a military group they belong to and they gain honor, courage, patriotic sentiment through their military costume. The purpose of this study was to investigate the originality the military costume as it changed and developed continuously from ancient Egypt, Greece and Rome to modern times. This study was performed to show the comparison and characteristic marks of the past, and the influence of them on the modern military uniform. The method used in this study was using past manuscripts of the early times, information attained from domestic and foreign military documents and previously written reports. As a result, the military costume was one of many means of expression of their natural and social environment. It can be said that the most epoche-marking and powerful changes to the social environment are revolution or war. War absolutely has influenced on the changes of the changes of costume and the military armour according to the type of war and the development of weapons. Especially using the amour, the main purpose that of protecting the body has changed into distinguishing our forces from the enemy and instilling fear into enemy, Furthermore, the class who has the power has used it in order to express their power and dignity. Therefore, armour had required two rules to not only protect the body but also discriminating between classes.

  • The purpose of this study is to identify the characteristics of monuments in the Seoul Foreigners′ cemetery at Yanghwajin, a place where many prominent Christian missionaries and other Christians have been buried near Choltusan. In considering the characteristics of gravestone details, the researcher has divided the details into 4 analysis categories: forms, symbols, epitaphs, and materials. For this research, 281 monuments were selected including 68 of missionaries, 26 of U. S. Army Soldiers, and 13 of teachers. The analysis revealed that there were 26 types of monuments. This includes simple and standardized types like the tablet, headstone, marker, and monolith. These were used more often than other shaped types such as the Cross, obelisk, sculpture, etc. Standardized types made in Korea have been preferred after the 1950s even though the beauty of the gravestones has been degraded. Symbolical decorations related to religious, social, professional or military emblems were also introduced to strengthen their symbolical objectives. Among them, fie Cross was the most predominant Christian symbol and emblem. The families wanted to inscribe epitaphs, the greater part of which originated from the Bible, poems, idioms related to tribute, rest, supplications to deity, love, achievement, to express human sentiment and religious faith. When using materials for making monuments, monument makers have mostly used stone because of its durability. Until the 1950s, various stones had been used to make monuments, for most marble and granite were brought from foreign countries. These were very different from the Korean white marble stone used for many monuments. After the 1950s, the source of stone has been limited to Korean stone, for Korean could make stone monuments that foreigners were agreeable. Especially, a black marble stone called "O-Suk" which means black stone, has been used as a main material. The study identified the following characteristics of monument details in the Seoul foreigners′ cemetery at Yanghwajin. First, Christianity has been applied as the main concept, while symbolizing the homogeneity of religious, family, social, professional or military groups by having the symbolic form, symbol, and epitaph in common. Second, monuments made after the 1950s have been standardized into unattractive and monotonous forms by the limited materials, and so the beauty of the monuments has been degraded.

  • This study, on the military fashion which has been inspired by the men's military uniform, is composed of an examination of the following; the aspect on the women's hi-fashion and the street fashion and the analysis of it's intention. On hi-fashion, from the 1960s to the early half of the 1970s, by the influence of the minimalism, maintained it's couture style, which is the formal image as well as moderating the line and simplifying the details, From the latter part of the 1970s to the 1980s, mannish image was sensed greatly by the wide shoulders with pads and large silhouette. The 1990's theme was the retro. Many different expression techniques appeared, but the trend was the retro. However, on the streets, young generation and hippies wore unisex army mode because of the influence of anti-war movement. Also, Hell's Angels, punks used black leather jacket with Nazi symbol, badge and eyelet expressed to show their aggressiveness as an avantgarde fashion. The intentions of military fashion can be analyzed as women's amazon need, the feeling of movement, and the spirit of rebellion.
