본 연구에서는 여대생들의 군에 대한 태도가 학군장교 지원의향에 영향을 미치는가를 규명하고자 한다. 이와 동시에 여대생의 학군장교 지원의향에 영향을 미치는 여군에 대한 이미지의 매개효과를 분석하고자 한다. 특히 군에 전문지식의 활용, 양성평등 의식, 군 가산점 제도 등의 군에 대한 태도와 군에 대한 다차원적인 이미지가 학군사관의 지원의향에 어떤 영향을 미치는가의 규명은 향후 여성병력 자원의 안정적인 수급과 사회체계와 연계한 정책입안에도 의미 있는 연구가 될 것이다.

In this paper, watermark embedding technique was proposed to securely conceal the watermark in color cover image by applying the spatial encryption technique. The embedded watermak can be extracted from stego-image without loss. The quality of the stego-image is very good. So it is not possible to visually distinguish the difference between the original cover image and the stego-image. The validity of the proposed technique was verified by mathematical analysis. The proposed watermark embedding technique can be used for intellectual property protection, military, and medical applications that require high security.

Target Detection in synthetic aperture radar(SAR) image is critical for military and national defense. In this paper, we propose YOLOv4-Attention architecture which adds attention modules to YOLOv4 backbone architecture to complement the feature extraction ability for SAR target detection with high accuracy. For training and testing our framework, we present new SAR embedding datasets based on MSTAR SAR public datasets which are about poor environments for target detection such as various clutter, crowded objects, various object size, close to buildings, and weakness of signal-to-clutter ratio. Experiments show that our Attention YOLOv4 architecture outperforms original YOLOv4 architecture in SAR image target detection tasks in poor environments for target detection.

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.

EOIS(electro-optical imaging system) is the main target of the laser weapon. Specially, the image sensor will be vulnerable because EOIS focuses the incident laser beam onto the image sensor. Accordingly, the laser-induced damage of the image sensor needs to be identified for the counter-measure against the laser attack. In this study, the laser-induced damage of the CCD image sensor irradiated by the CW(continuous wave) NIR(near infrared) laser was experimentally investigated and mechanisms of those damage occurrences were analyzed. In the experiment, the near infrared CW fiber laser was used as a laser source. As the fluence, which is the product of the irradiance and the irradiation time, increased, the permanent damages such as discoloration and breakdown appeared sequentially. The discoloration occurred when the color filter was damaged and then the breakdown occurred when the photodiode and substrate were damaged. From the experimental results, LIDTs(laser-induced damage thresholds) of damages were roughly determined.

Neo-Confucianism was the dominant ideology of the Joseon Dynasty Korea. Male and female costumes reflected a clear distinction in male and female sex roles. This study analyzes cross-dressing in sword dance performances. The research method examines relics, paintings, pictures, and documents relevant to sword dance costumes as well as for the military. The results are: First, the composition of sword dance costume was jeogori (upper garment), skirt, and shoes with military costume of jeollip (hat), jeonbok (long vest), and jeondae (belt). Second, the sword dance costume and military costume are very similar except for the basic inner wear, shoes, some details and methods of wearing. Third, the sword dance costume gradually adopted military items and features. The sword dance costume was basically female, with overall additions of a male costume, to express an androgynous image; however, the cross-dressing phenomena in the sword dance were not intended for the pursuit of sexual pleasure.

There are many kinds of military images used in naval combat system because various sensors are operated. The military images are displayed, analysed and stored with analysed informations according to the tactical purpose on combat system. These images are used to target detection, analysis and classification. Thus the analysed information and images must be secured, the information hiding methods are the most eligible solutions to get secured informations and images. In this paper, the hybrid information hiding method based on the characteristics of the military images is proposed and the effectiveness is shown by experiments.

The previous steganographic methods by using the interpolation were difficult to estimate the distortion because the size of cover image is extended by interpolation algorithms. In this paper, to solve the problems of previous methods proposed the improved steganographic method based on the pixel replacement algorithms. In our method, we cannot extend a cover image, but also can estimate exactly the distortion of the stego-images. In the experimental results, the estimated distortion and embedding capacity of stego-image are shown on three pixel replacement methods.

This paper presents the development of the automatic safety inspection technique for the ammunition fuzes using radiography images. The technique inspects 49-ammunition fuze by detecting the X-ray or neutron radiographic images to check whether the fuze is unintendedly armed or/and some major assembled parts are at right place. To execute the program, we loads the image(s) for under test. After reading images, the program conducts a series of pre-image processing, and then starts inspecting input images by using the detection algorithms which are designed distinctively for each fuze. After completing the detection process, the program displays the final result of the fuze status: "safety or danger." Through this program, we can cut off the fuzes which have any doubt about safety, and can only provide absolutely safe fuzes, compared with the current naked eye inspection method.
