Traditionally, a design has been applied on a various defense area for the improvement of the mobility, reducing the radar detection area and other reasons. In case of Korean Wheeled Armored Vehicle(WAV), a design has been also applied for retaining the agility and threatening feature in the battlefield. However some figures has been changed because of constraints such as assembling and manufacturing in the development stage. Today, the government has planned to develop the Wheeled Armored Command Post Vehicle(CPV), a variant of WAV, and it is necessary to apply the latest design trend, which is suitable for the concept of the CPV, on it.

C4ISR 체계는 군사작전 지휘통제를 위한 중요 수단이다. 그러므로, 지휘통제체계의 마비를 위한 각종 변형된 사이버테러 시도에 노출되기 쉽다. 일반적인 정보체계는 IDS와 방화벽을 주요 정보보호 수단으로 활용하고 있으며, C4ISR 체계 역시 IDS와 방화벽을 주요 정보보호 수단으로 활용하고 있다. 그러나, IDS의 예상외의 행위패턴에 대한 잦은 오탐지와 변형된 공격패턴에 대한 미탐지로 인해 C4ISR 체계에서의 IDS의 활용이 제한되고 있다. 이번 연구에서는 IDS 탐색과정에서 변형 공격패턴이나 예상 외의 패턴을 자동 생성하는 IDS 구조를 제안한다. 제안하는 IDS 구조는 패턴의 생성과 검증을 통해 오탐지 또는 미탐지를 감소시킴으로써, C4ISR 체계에서의 정보보호를 향상시킬 것을 기대한다.

The virtual target signal generator was developed to verify the shipborne tracking radar performance. It was used to DRFM(Digital RF Memory) method to generate the virtual moving targets. The target signal includes Doppler shift and RCS according to the target motion. And the signal generator can make jamming signal and clutter to test shipborne radar performance at real environmental condition. This paper described the functional diagram and the hardware configuration items to meet the test requirements for the tracking radar. And it showed the critical design points for the sub-systems. The signal generator which was developed in this paper shared the operational information of the radar with the radar command and control part. To test the frequency agility of the radar, it had the local oscillator which could do high speed frequency switching according to radar information. By communicating between the signal generator and the radar command and control part, the local oscillator of signal generator could be controlled every pulse. It reduced the instantaneous bandwidth of signal generator and minimized the spurious. So it lowered the probability of generating wrong targets.

MicroRNAs (miRNAs) play roles in the clinic, both as diagnostic and therapeutic tools. The identification of relevant microRNAs is critically required for ovarian cancer because of the prevalence of late diagnosis and poor treatment options currently. To identify miRNAs involved in the development or progression of ovarian cancer, we analyzed gene expression profiles downloaded from Gene Expression Omnibus. Comparison of expression patterns between carcinomas and the corresponding normal ovarian tissues enabled us to identify 508 genes that were commonly up-regulated and 1331 genes that were down-regulated in the cancer specimens. Function annotation of these genes showed that most of the up-regulated genes were related to cell cycling, and most of the down-regulated genes were associated with the immune response. When these differentially expressed genes were mapped to MiRTarBase, we obtained a total of 18 key miRNAs which may play important regulatory roles in ovarian cancer. Investigation of these genes and microRNAs should help to disclose the molecular mechanisms of ovarian carcinogenesis and facilitate development of new approaches to therapeutic intervention.

Image blurring in airborne camera can be prevented through timely actuation of LOS(Line of Sight) into the opposite direction to the aircraft advancement, i.e. FMC(Forward motion compensation). Performance verification of FMC requires installation of camera to the aircraft. However, in many ways the verification process has little choice but to be implemented in the laboratory. In this paper verification method of FMC performance in the laboratory is introduced. With collimator target installed in the known reference position image obtained by actual mission plan naturally displays image blurring as well as LOS displacement by FMC effect. Through comparison of the amount of those image blurring and LOS displacement to the equivalent image distortion expected by the application of the FMC reference command can the performance be verified. In this paper we propose a new verification method of FMC performance in laboratory along with generalized solution of FMC reference command, and assess the validity of our proposition.

It is well known that nitroglycerin(NG) may evaporate and migrate from the triple base propellant grains in storage. This physical process makes it double base environment to the CCC(combustible cartridge case) which is based on nitrocellulose(NC) without NG. Meanwhile, it is not appropriate to use diphenylamine(DPA) as a stabilizer for CCC in this double base environment because of incompatibility between DPA and NG. So we estimated the shelf life to study the effect of NG migration from propellant to CCC by following the procedures in the STANAG 4257. And we found out that CCC with ethylcentralite(ECL) has 7.5 years longer shelf life than with DPA, when NG migrates to CCC from triple base propellant grains.

Low Frequency Active Sonobuoy(hereinafter referred to as LFAS) are being developed in Korea in consideration of compatibility with existing overseas sonobuoys, and a communication device for acoustic signals receiving and operating control of LFAS has been developed. The communication device needs to verify compatibility with the existing Sonobuoy, and for this purpose, the standardized Sonobuoy communication protocol was applied. The communication device is designed/manufactured to transmit the acoustic signal received in real time from the Sonobuoy through VHF band RF communication to the data processing device, and transmit CFS/CSG commands for operation control to the Sonobuoy through UHF band RF communication. In order to verify the manufactured communication device, the communication status and performance were verified by interlocking test through Ultra Electronics' PASS-II equipment and domestically developed electronic device of Sonobuoy. In addition, operability was verified through environmental tests, water tanks, and marine operations. In the future, the communication device of sonobuoy can be used for verification of the Sonobuoy developed in Korea.

This research seeks to examine the relationship between multicultural education experiences and the multicultural acceptability of military officers. The sample included 552 Republic of Korea Army officers and non-commissioned officers(NCOs) who were located in Gangwon-Do and Gyeonggi-Do. For the statistical analysis, SPSS 18.0 was used to perform descriptive statistical analysis, frequency analysis, differential verification, and multiple regression analysis. The major analysis results are as follows: First, The multicultural acceptability of the military officers and NCOs, including sub-factors, was above the mean level; in terms of the ranking per sub-factor, the scores were in the order of diversity, relationship, and universality. The experience frequency of the targets and the evaluation was lowest in the educational experience within the military, and the evaluations were in the order of public media, school, and military. Second, The differential verification, depending on the characteristics of the sociology of the population and the existence of the multicultural educational experience, showed that the duration of education(personal factor), marital status(family factor), existence of a foreign relative(family factor), and existence of experience of managing multicultural personnel as soldiers under command(military-related factor) showed a significant difference in multicultural acceptability. Additionally, the existence of multicultural education through schools and public media lead to a significant difference in multicultural acceptability, but the existence of education within the military did not lead to a significant difference. Third, The analysis of the influencing relationship through multiple regression analysis showed that the higher the evaluation of multicultural education through the military, school, and public media, the higher the multicultural acceptability.Therefore, this research proposes multicultural educational plans that may improve the multicultural acceptability of military officers and NCOs as a way to establish a multicultural composition in the army.
