Recently, the level of science and technology in our country has reached the level of the advanced countries. However, the level of standards/specifications was insufficient for support. In this study, after a review of the international atmosphere on defense specifications/standards and an investigation of the domestic present situation, three different perspectives of improvement scheme for the defense specifications/standard system are presented. First, in the defense standard classification system perspective, specifications, standards and handbook were defined based on their characteristic and properties. Second, in the perspective concerning the establishment procedure of defense standards/specifications, the bottom-up approach was suggested. Finally, in the perspective of the 'defense standards/specifications instructions', a reinforced drawing number system and other factors to overcome the current limitations are provided.

This study examined the trend of standards established in the United States and to find points that can be applied to Korean defense standards. The titles of various United States defense standard documents registered on the web were selected for this research. The wordcloud was created after analyzing the frequency of words appearing in the title using text mining. The trend of words appearing in MIL-STD by era was obtained. This study identified words that appear often due to the format of the document itself, words that appear regularly throughout the era, words that are used frequently in the past but are not used much in the present, and words that did not receive attention in the past but appeared recurrently in the present. In addition, the characteristics of each document were derived through the wordcloud produced for various defense documents. In conclusion, Korean defense standards also require a consideration of safe and efficient management, transport, and load design of hazardous materials. Furthermore, the quality of defense standards can be expected to improve if the defense standard document system can be established, focusing on efficient management.

AI is accepted not only in the private sector but also in the defense sector as a cutting-edge technology that must be introduced for the development of national defense. In particular, artificial intelligence has been selected as a key task in defense science and technology innovation, and the importance of data is increasing. As the national defense department shifts from a closed data policy to data sharing and activation, efforts are being made to secure high-quality data necessary for the development of national defense. In particular, we are promoting a review of the business budget system to secure data so that related procedures can be improved to reflect the unique characteristics of AI and big data, and research and development can begin with sufficient large quantities and high-quality data. However, there is a need to establish standardization and quality standards for structured data and unstructured data at the national defense level, but the defense department is still proposing standardization and quality standards for structured data, so this needs to be supplemented. In this paper, we propose an unstructured data set standard format for defense unstructured data sets, which are most needed in defense artificial intelligence, and based on this, we propose a standardization method for defense unstructured data sets.

This paper presents hardware implementations of the two representative cryptographic algorithms, Advanced Encryption Standard (Rijndael), and the present American federal standard (Triple DES) using a PCI- based FPGA board named "EBSW-1" This board bases on a FPGA chip (Xilinx Virtex300 XCV300PQ240-4). The implementation results of these two algorithms were tested successfully. AES circuit could proceed an encryption as well as a decryption two times faster than the Triple-DES circuit, while the former circuit used higher rates of CLBs. Besides, if these architectures use pipeline-registers, the processing speed will be increased about 1.5 times than the presented circuits.

A high Reynolds number transonic wind tunnel has been built in 2018 at Agency for Defense Development(ADD). The tunnel has a closed circuit with a 1.5m×1.5m test section and is injection driven from a 140bar air supply system. The Mach number range is 0.3-1.2 with a conventional contracting nozzle and 1.4 with a convergent-divergent contraction. The stagnation pressure range is 100-550kPa at the lowest Mach number. An AGARD-B standard model is tested in the transonic wind tunnel to obtain 6-DOF aerodynamic coefficients. The results are compared with those obtained from ADD trisonic wind tunnel and others. We verify that the transonic wind tunnel become available to develop an aircraft from the testing results.
