Unmanned aerial vehicles(UAVs) operating in the military for various purposes are designed to transmit information collected according to the purpose to GCS(Ground Control System), and to transmit/receive the vehicle's operational control and status information using wireless communication(or datalink). Currently, the military UAV systems in operation in Korea use unique communication methods, protocols, and message structures for each system. In this paper, we analyze the TM/TC data protocol of two types of military UAV systems currently under development and propose a more efficient TM/TC message design scheme in wireless communication(or datalink) environment. And we will discuss issues to be considered for standardization of technology for ensuring interoperability with many UAVs or newly introduced UAV systems.

Development of high technology especially in telecommunication and precise weapon systems will impact the future battle field environment. So it is not difficult to anticipate the environment of military command and control system will be changed rapidly. Considering these future battle field environment, military needs automated C4I (Command, Control, Communication, Computer and Intelligence) system, namely real time decision support system which is combined high technologies. Most of advanced countries have been studied and developed these kinds of systems and already applied these systems in real military operations. In order to take a military initiative in Korea peninsula it is essential to catch up with this trend and procure C4I system. The purpose of this research is to present the method and the direction of optimal C4I system development model. First we survey the related theory about C4I systems. Second we present the conceptual framework for C4I system concept development. Third we model the system using Timed Petri-Net and perform simulation. Finally we analyze the through-put time and suggest alternatives. If we model using the real organization structure, operational tasks and various situations then optimal C4I system would be developed.

This study aimed to clarify relationships between the westernization of military uniform systems and changes in the textile import industry during the Eulmi reforms of clothing regulation. For the goal, the study investigated the content and features of that had been enacted under the Eulmi reforms. It also examined the status of the textile import industry at the time, especially in relation to outer garments such as jackets or Eui, trousers or Go, and overcoats. Moreover, this study inspected how the above westernization changed the textile import industry. More specifically, the research analyzed the content of based on articles from the then state newsletter or 『Gwanbo』, and the then cabinet meeting or Euijeongbu's proceedings or 『Euiju』. Concerning the textile import industry, this study looked into relevant descriptions and trade statistics from 『KOPEИ(Hankukji)』, and analyzed changes in that industry in connection with the introduction of Western military uniform systems. As a result, this study found that increased imports of cotton fabrics during the Eulmi reforms of clothing regulation was correlated with surging demand for shirt or lining materials and increase in the use of Myeonyung following military uniform westernization. Similarly, an increase in silk fabric imports was an outcome of increased demand for lining materials. Also, the import growth of woolen fabrics was seemingly attributed to the use of Heuknasa and Heukyung as basic materials of military uniforms. Thus, military uniforms began to be made of fabrics, which hadn't been used before in the wake of westernization. This development brought changes in the textile import industry, which is supported by textile import statistics of the time. In conclusion, the westernization of military uniform systems under the Eulmi reforms of clothing regulation was a significant factor that changed the industry.

It is essential for the combined military weapon system to be equipped with interoperability for the efficient combat operation in the modern warfare environment. Since most of modern military systems utilize the electromagnetic wave for the radio communication in the network-centric warfare system, they can be vulnerable to the mutual interference among the adjacent combined military systems. In this paper, the typical radio communication systems are modeled with the modulation types of both spread and non-spread spectrum system. The various interference signals were generated for the simulation of the mutual interference influence from the adjacent radar and communication systems. The simulation results show that the detection performance of the victim communication receiver is seriously affected by the various interferences such as the types of modulation and the ratio of the overlapping bandwidth of the adjacent interferers. This result will be useful for defining the criteria of the interference protection in the combined military system for the interoperability in the future.

Recently, management based on statistical data has become a big issue and the importance of the statistics has been emphasized for the management innovation in the defense area. However, the Military Management based on the statistics is hard to expect because of the shortage of the statistics in the military. There are many military information systems having great many data created in real time. Since the infrastructure for gathering data form the many systems and making statistics by using gathered data is not equipped, the usage of the statistics is poor in the military. The Analytical Defense Statistics System is designed to improve effectively the defense management in this study. The new system having the sub-systems of Data Management, Analysis and Service can gather the operational data from interlocked other Defense Operational Systems and produce Defense Statistics by using the gathered data beside providing statistics services. Additionally, the special function for the user oriented statistics production is added to make new statistics by handling many statistics and data. The Data Warehouse is considered to manage the data and Online Analytical Processing tool is used to enhance the efficiency of the data handling. The main functions of the R, which is a well-known analysis program, are considered for the statistical analysis. The Quality Management Technique is applied to find the fault from the data of the regular and irregular type. The new Statistics System will be the essence of the new technology like as Data Warehouse, Business Intelligence, Data Standardization and Statistics Analysis and will be helpful to improve the efficiency of the Military Management.

This study simulated the effect of the quantity flexibility contract(QFC) on the Korean military inventory system. The results shows that the QFC make the inventory system more efficient. For validity of this study, we assume the basic four demand patterns (increase, decrease, high variation and long seasonality) which are the exogenous variables of these simulation systems. We measured the difference of the traditional military inventory system's and new QFC system's performances. Under the all demand patterns, QFC models have little inventory than the traditional systems. We suggest, therefore, the military change the supply contract into QFC for decrease inventory and expect the results of this study applied to the company level.
