This research established that the two characteristics of Femail Gugguek were explored on the character as genre and the nationalism discourse. This research also included how to encounter the characteristic of Female Gugguek as a popular entertainment with the social context at the time and how to re-produce the social ideology. The 'historical nationalism narrative' piercing Female Gugguek had the close relation with the nation/state discourse of the time. The history reproduced by Female Gugguek was not real. It was the imagined past, the history as image. The Female Gugguek was a genre which typically showed how to intermediate fantasy, ideology and narrative. The happy-endings with the victory of male hero, the narrative pattern on overcoming national crisis, the narrative emphasizing the glorious past and the unification of nation, all these were projected the discourse on nationalistic ideology and nation/state-making in 1950's. The Utopian desire of Female Guggeuk imagining the glorious past and strong nation was the fantasy which concealed the contradiction in real life and the national identity damaged by colonial experience, division of territory, governance by U.S. Military Government and the Korean War. The Female Guggeuk was doing well, because it had amusement. Futhermore, imagination of glorious past and strong state/nation of Female Guggeuk satisfied the public's desire of escapism and wish to establish their position and identity in the rapid social-economic changes. However, Female Guggeuk repeatedly produced the never-changing characters, narrative pattern and conservative world-view. Thus, it became regarded as immature and obsolete thing in late 1950's. Female Guggeuk, which kept re-producing the retrogressive image of the past without modern viewpoint and interpretation, was not sensitive about change of time and trend of the people. Consequently, it was pushed out of people's major interest.

In the 1960s, both South and North Korea needed to stabilize their regimes, and propaganda films were at the core of establishing this purpose. South Korea claimed legitimacy of a military government and called for service to fulfill the government's mission of the era, while North Korea emphasized the impeccability of their leader and the superiority of their socialist system. This study investigates image reproduction strategies used in South and North Korean propaganda films at the time under the context of domestic and foreign environments in the 1960s. First, South and North Korea portrayed their rulers as a strong leader and friendly leader, respectively, to establish legitimacy. Second, South and North Korea tried to image the same incident from different views in order to instill the spirit of age defined from their own perspectives. Third, propaganda films at the time portrayed desirable images of citizens (people) and visualized a flawless government. Authoritarian governments in South and North Korea in the 1960s facilitated the establishment of the so-called official society through propaganda films.

Currently, the demand for underwater or underwater photography is growing very fast. Its coverage of underwater shooting for broadcasting, leisure and sports, and military and operational use is also growing rapidly. Among them, we specifically select the best camera to be used in underwater drones to photograph and inspect marine life attached to the ship's hull. To compare three cameras performance, they are compared and evaluated using objective and subjective criteria in special circumstances such as underwater shooting. This study checks whether performance criteria, such as resolution of a camera, meet objective and subjective standards in the unusual situation of underwater shooting. And it shows that in addition to the filter that calibrates the image, proper camera selection is important for providing good picture quality. Even after this study, research using more diverse cameras could provide an appropriate standard for comparison of underwater camera quality.

High-quality images have a lot of information, so sensitive data is stored by encryption for private company, military etc. Encrypted images can only be decrypted with a secret key, but the original data cannot be retained when attacked by the Shear attack and Noise pollution attack techniques that overwrite some pixel data with arbitrary values. Important data is the more necessary a countermeasure for the recovery method against attack. In this paper, we propose a random number generator PingPong256 and a shuffling method that rearranges pixels to resist Shear attack and Noise pollution attack techniques so that image and video encryption can be performed more quickly. Next, the proposed PingPong256 was examined with SP800-22, tested for immunity to various noises, and verified whether the image to which the shuffling method was applied satisfies the Anti-shear attack and the Anti-noise pollution attack.

Rider jackets were once reserved for military uniforms but have become an important styling item in recent fashion trends. The design characteristics of the rider jacket are rooted in symbolism, and the image associated with a rider jacket is in line with the challenging of authority and being a member of the rebellious youth subculture. Usually, young people with anti-social tendencies wore jackets, and some styles were used as a medium to express their emotional homogeneity, and they received favorable responses as the items represented them. The design characteristics of a rider jacket can be largely divided into resistance against the older generation, violence, challenging cultural norms, sexuality, and resistance, as well as embodying violent characteristics, including strength, courage. and male chauvinism. The reason for the development of these challenging characteristics are disparagement and anger of the lower class, who were excluded from mainstream society. Rider jackets can be viewed negatively due to the kind of message it is conveying against mainstream society. Among the sexual features were leather pants, short-length leather rider jackets, glossy metal accessories, and belt buckles, which also highlighted gay and decadent images that came to be associated with the jackets. The drapery created various kinds of wrinkles according to the way of dressing, and it had beautiful expressiveness while serving to express the body more beautifully. Drapery can be classified according to the aesthetic characteristics or expression techniques, and if the type of drapery is classified according to the morphological characteristics, it can be classified into variable and fixed structures, depending on whether the part to which the drapery is applied is fluid or not. In other words, it depends on the dressing method or the intention, and if the drapery technique is directly applied to the garment or is attached to the form. This fashion design proposal may have the greatest significance in that it sought to propose a new style incorporating a drapery technique with a strong feminine image to a rider jacket, which traditionally was associated with a masculine image.

In this paper, an effective feature which is capable of classifying targets among the detections obtained from 2D range-bearing maps generated in active sonar environments is proposed. Most conventional approaches for target classification with the 2D maps have considered magnitude of peak and statistical features of the area surrounding the peak. To improve the classification performance, HOG(Histogram of Gradient) feature, which is popular for their robustness in the image textures analysis is applied. In order to classify the target signal, SVM(Support Vector Machine) method with reduced HOG feature by the PCA(Principal Component Analysis) algorithm is incorporated. The various simulations are conducted with the real clutter signal data and the synthesized target signal data. According to the simulated results, the proposed method considering HOG feature is claimed to be effective when classifying the active sonar target compared to the conventional methods.

LiDAR(Light Detection and Ranging) technology provides realistic 3-dimension image information, and it has been widely utilized in various fields. However, the utilization of this technology in the military domain requires prompt responses to dynamically changing tactical environment and is therefore limited since LiDAR technology requires complex processing in order for extensive amounts of LiDAR data to be utilized. In this paper, we introduce an Unmanned Aircraft Platform Based Real-time LiDAR Data Processing Architecture that can provide real-time detection information by parallel processing and off-loading between the UAV processing and high-performance data processing areas. We also conducted experiments to verify the feasibility of our proposed architecture. Processing with ARM cluster similar to the UAV platform processing area results in similar or better performance when compared to the current method. We determined that our proposed architecture can be utilized in the military domain for tactical and combat purposes such as unmanned monitoring system.

Synthetic aperture radar(SAR) has been widely used for reconnaissance. It provides high-resolution, day-and-night and weather-independent images for a multitude of applications. Because SAR coherently combines many viewing angles to effectively create a large aperture(narrow beam) radar, the test-bed should be capable of moving straightly SAR sensor for the integration angle to meet resolution. This paper describes the test-bed developed to test and evaluate the SAR performance. It forms high-quality images in real time and saves the raw data for the purpose of post processing on the ground.

In this paper, we present a method for estimating of position and velocity of a moving target by using the range and the bearing measurements from multiple sensors of aiming unit. In many cases, conventional low cost gyro sensor and a portable laser range finder(LRF) degrade the accuracy of estimation. To enhance these problems, we propose two methods. The first is background image tracking and the other is principal component analysis (PCA). The background tracking is used to assist the low cost gyro censor. And the PCA is used to cope with the problems of a portable LRF. In this paper, we prove that our method is robust with respect to low-frequency, biased and noisy inputs. We also present a comparison between our method and the extended Kalman filter(EKF).
