With advancements in satellite technology, interest in target detection and identification is increasing quantitatively and qualitatively. Synthetic Aperture Radar(SAR) images, which can be acquired regardless of weather conditions, have been applied to various areas combined with machine learning based detection algorithms. However, conventional studies primarily focused on the detection of stationary targets. In this study, we proposed a method to identify moving targets using an algorithm that integrates sub-aperture SAR images and cosine similarity calculations. Utilizing a transformer-based deep learning target detection model, we extracted the bounding box of each target, designated the area as a region of interest (ROI), estimated the similarity between sub-aperture SAR images, and determined movement based on a predefined similarity threshold. Through the proposed algorithm, the quantitative evaluation of target identification capability enhanced its accuracy compared to when training with the targets with two different classes. It signified the effectiveness of our approach in maintaining accuracy while reliably discerning whether a target is in motion.

The purpose of this study is to analyze the symbolic meaning of the Tiger in Korean Folk Paintings, Minhwa, (hereafter, Minhwa) connected to its social contexts in Joseon period. Thinking of the Tiger Minhwa as a 'visual language' and regard the Tiger as a 'visual signifier' as well as the united-signifiers such as a Korean magpie, pine tree and so on in Minhwa. This research is to analyze these signifieds, 'Signified', what we say in this paper, have composed its symbolic meaning related to the social 'ideological complexes' and collective consciousness during Joseon period. In a word, the characteristic of the Tiger signifier has changed and spread out from the ideal trend to a worldly one. Since the late Joseon period, the change of the social contexts was, because of the civil classes who recognized the limitation of the Sung Confucianism(the doctrines of $Chi-Tz\={u}$), the predominated ideology of that time. To get rid of their uneasiness, they brought the Shamanism, Taoism and Buddhism at the front which were usually the lower class ideology or belief and tried to construct the collective consciousness and safety of their real lives. Therefore, the trend of this 'common conceptualization' show us the positiveness and flexibility to the Tiger signifier through the variation, appropriation and producing signifier. Moreover, even to the same Tiger, there were various meanings and most of them were concentrated in the meanings as follows ; Beoksa(in Korean term is to drive away evil spirits) and Gilsang, which is the good omen of a luck. All these were based on the value of 'this world'. In conclusion, through this research, the concept of the Tiger as a apotheosis has lowered its statutes and being secularized.

Mammals act as an important role in maintaining ecosystem, but direct observation is very difficult. Nevertheless, in order to understand the impact of various changes about a sudden environment, long-term monitoring through direct investigation is essential. This study investigated home range analysis using GPS tracking device and behavioral ecology of Korean waterdeer (Hydropotes inermis), indigenous and native species in Korea. Studies on ecological characteristics and home range of Korean waterdeer are insufficient. Therefore, we studied home range using the GPS technique for critical point of existing research. Data showed the active movement in daytime ($44.1km^2$) than night ($30.0km^2$) and large area of activity in winter ($3.7km^2$) and spring ($44.1km^2$) than summer($0.04km^2$) and autumn ($0.01km^2$). The most used area of Korean waterdeer was forested area and wetland, agricultural area, waters in order of frequency based on the land coverage map. Our research represents overall characteristics of Korean water deer due to measurement of area of activity. However, this research signified behavioral ecology for Korean waterdeer, and further investigation in necessary.

As an art group, De Stijl (1917-1931) led a total art movement encompassing painting, sculpture, design, and architecture. Among these, architecture, as a model of the total art pursued by the group, was encapsulated by the term 'plastic architecture.' The term reflects architecture's shared features with plastic art, especially its pictorial characteristics. Firstly, De Stijl architecture shares geometric form with painting. Assembled in simple, clear and rational structures, the geometric forms signified universal forms, and extended the pictorial experimentation that Mondrian exercised through Neo-Plasticism to architecture. Constructed with colour fields made of concrete wall, De Stijl architecture is geometric abstract painting embodied in space. Together with such pictorial characteristics, large plate glass windows, narrow window frames, and cantilever structure minimize the building's visual weight. De Stijl architecture, which appears suspended in the air, is an architectural version of the abstract paintings of the era that revealed unknown spaces beyond perspective. De Stijl architecture is also an 'open' architecture, where the units placed as if radiating from the center form relations with each other flexibly and organically. The observer in such a space is encouraged to experience space within time, as his/her physical and visual mobility and extension are maximized. De Stijl architecture is an example of how the time-space continuum, represented within picture frame through Cubism, Futurism, and abstract art, can be realized in space. By transforming the ideal space of painting into real space in this way, 'plastic architecture' turned out to be an architectural manifestation of the utopianism of the era, aimed at building a society in 'perfect harmony.' However, such rationalism and universalism are not free from the violence of totalization that deletes various differences. This is evident in the history that followed as the geometric form of architecture and urban planning proliferated across the globe, engulfing the diverse natural landscapes and local cultures.

In this paper, I am going to analyze a commercial film narrative focused on a temporal order through the theory of narrative discourse by Gerard Genette. Advertisements has a special quality or feature to be convertible into mythological hyper reality to advertise an product effectively. In this process, narrative in a commercial film has visual variations using a temporal order to show an glamorously advertisements in television. The reason that narrative in a commercial film is subject to variation with a temporal order, duration, frequency is to get some aesthetic effect for making sure people see them. Under the influence of postmodernism, image making like a pop-art became the first consideration in a commercial film with the consequence that representation as a signifier came to be more important than object as a signified. As a commercial film have more sensational image as a result of visual variation, images in a commercial film became vague so that it does not explain or express an advertising concept dearly. However, those aspects have assets that it gives the TV audience a room for interpretation in advertisements by themselves.

The purpose of this study is to examine the romantic costume style which has become a big trend before and after the 21th century. For this purpose, I examined the development plans and characteristics of women's costume in France in the Romantic period from the 1820s to the 1850s and analyzed the aesthetic characteristics of romantic costume style The aesthetic characteristics of romantic style in the 19th century were defined by the feminine and elegant beauty, exoticism, and sensuality. Since the 1990s, the characteristics are classified into Feminine & Elegant Style, Ethnic & Fusion Style, and Sensual Style. Feminine & Elegant Style is characterized by delicate, splendid lace and frill decorations that have become more ornamental and technical since the 1990s. They create greater romance and express gentler and more elegant femininity away from the artificial silhouette. Ethnic & Fusion Style use more diverse ethnic patterns, colors, accessories, and details since the 1990s and shows more varieties and creativity in convergence with modern fashion. Sensual Style exposes the physical curve of female body. In the 19th century, cuffs and collars were exaggerated and shoulders were exposed for sensuality. After the 1990s, however, see-through materials have been used to show the beauty of natural physical curves or corsets have been worn as the outerwear. Studying romantic costume style, which arose as a concept of postmodernism, the cultural ideology that exists as a breakthrough of our time, is signified by the understanding of the latest cultural phenomenon and fashion trends.

Currently, there is a gradual increase in double-income households in our country, and one-child families gradually become the norm as well due to a decrease in the birth rate. The purpose of this study was to examine the characteristics of spatial use and furniture arrangements in the residential spaces of one-child double-income households in an effort to be of use for spatial planning suitable for their living. 30 cases of double-income households whose children's ages ranged from infancy to secondary school years were visited to have in-depth interviews and make on-site inspections. The findings of the study were as follows: First, the most common spatial use pattern for three bedrooms was using one for the parents, another for their child and the third for personal computers and clothing storage. It signified that the parents and their child used one room respectively, and that there were personal computers and clothing in the third room. Second, as for the pattern of using the rooms according to furniture arrangements, there were great disparities in that regard according to child age. It implies that there were differences in their living and needs for furniture arrangements according to their children's growth. The findings of the study made it possible to determine the state of living in the double-income households in detail, and suggest that differentiated house planning is required depending on children's age groups.
