  • Frequency-space domain full-wave tomography is a promising technique for delineating detailed subsurface structure with high resolution. However, this method requires criteria for the selection of a set of optimal temporal frequency components, to achieve stability in the sequence of inversion processes together with computational efficiency. We propose a method of selecting optimal temporal frequencies, based on wavenumber continuity. The proposed method is tested numerically and is shown to be able to select an optimal set of frequency components that are sufficient to image the anomalies.

  • This paper considers fuzzifying topologies, a special case of I-fuzzy topologies (bifuzzy topologies) introduced by Ying [16, (I)]. It investigates topological notions defined by means of regular open sets when these are planted into the frame-work of Ying's fuzzifying topological spaces (in ${\L}$ukasiewwicz fuzzy logic). The concept of fuzzifying nearly compact spaces is introduced and some of its properties are obtained. We use the finite intersection property to give a characterization of fuzzifying nearly compact spaces. Furthermore, we study the image of fuzzifying nearly compact spaces under fuzzifying completely continuous functions, fuzzifying almost continuity and fuzzifying R-map.

  • Along with the spotlight of storytelling, storydoing has attracted public's attention as it has been utilized in various different areas. There are valued message by producer and story to back it up in the storydoing. Recipient will acknowledge the affordance encouraged by producer and confirm the message by practicing it. Finally producer will evaluate the practice process. Therefore, storydoing promotes the product of company, strengthens the brand image and delivers message and value through a previously mentioned cycle. Ultimately, storydoing is operated based on user's experience. In this study, based on the experience theory of John Dewey, in order to discover how the interactivity and continuity operate story doing, we conducted a study on the concept of storydoing, the national and international story doing status, the difference between storytelling and storydoing, the elements of story doing, the relationship with user experience, and the principle of operating story doing. As a result, we learned that story doing had the five elements of message, story, characters, action, and confirmation, and operated by the interaction and continuity between the producer and receptor. Thus, through this research to understand the nature of storydoing, we have identified new trends of the cultural industries and discovered the possibilities to expand the application scope of storydoing, which was currently applied by companies to promote their brand images, onto contents field. More importantly, the proposal of theoretical differences between storytelling and storydoing makes this report meaningful in terms of sociocultural, industrial and academic aspect.

  • Haizi, who ended his life with suicide on the railroad at the age of 25, is a poet who implemented his unique poetic world alone without belonging to any of the existing Chinese poetry schools in the 1980s. The process that Haizi reveals self-inside through a poetic work is rather to hide self-inside paradoxically, too. Accordingly, even a work of figuring out the real intention, which is hidden in poetic dictions that he selected, will be meaningful. In this sense, this study tried to inquire into the poetic imagination and self-image that were revealed in poetry focusing on "Spring, Haizi of 10 People", which is a work of having his name as topic, with having been written at the time of suicide, among Haizi's many poetic works. In addition, it figured out Haizi's private conscious world through analyzing the poem titled "Facing the sea with spring blossoms", which was created ahead of death same as "Spring, Haizi of 10 People". Thus, the aim was to look back on significance of his death and to broaden the width of understanding about Haizi's poetry. As for Haizi, the death can be regarded as the completion of 'performance,' which is a kind of Haizi's own final art form. Hence, Haizi's suicide needs to be seen from the perspective dubbed the continuity of creation through this performance, not the discontinuance of creation caused by 'intended death' that the poet himself selected. In the wake of pursuing the poetic world of a gifted poet Haizi, who died early, that this study examined, there will be any poet of Korea who is recalled naturally. One poet will be first recalled Yi Sang, who is a poet and a novelist of having been broadly known. Another poet is overlapped Gi Hyeong-do, who had been active as a poet and a journalist of having been dead after living in the similar period to Haizi. A comparative analysis among works by these Korean and Chinese poets has similarity beyond the temporal space. A research on this is thought to have value of being considered a little more deeply and generally hereafter. Still, this study mentioned only possibility of a comparative research on this.

  • This study was conducted on characters who play the main character of the spin-off work based on the image in the original. Through the analysis of the original and spin-off works, the role type and characteristics according to the characters' roles were analyzed. It was analyzed that Rex, Bo Peep, and Forky, the main characters of the Toy Story spin-off works, had characteristics described in the original, which were not the main characters, and changed when they appeared in the spin-off works. First, it shows a tendency to add a new personality to play the role of the main character who solves problems and leads the story development while maintaining the existing personality characteristics in the original. Second, in order to play the main character in the spin-off work, these main characters are strongly revealed in the characteristics of the faithful type 6, and the achiever type 3, respectively. The reason why the characters' personality in the existing original have continuity is that if the personality of the existing characters change rapidly, they may contradict the audience's existing perception, preventing them from being immersed in the spin-off protagonist itself and the story development. However, the main characteristics of personality type 6 and personality type 3 are described only by considering the character's role as a helper to solve the problem and the characters' characteristics, but in order to solve the problem in spin-off, the animation producers are determined to achieve the goal. An understanding of this result will greatly help animation producers plan the character in consideration.

  • In this paper, in order to compose the visual perception cognitive function training content that can be linked with the IPUZZLE image block, an interactive content device that utilizes photos and videos of smartphones. Four areas of visual memory, visual continuity, spatial relationship, and visual discrimination were derived and the content operation, application method, and scenario were written. It was intended to continuously give and induce children's desire to participate in training by designing the content image and developing the existing learning terrain visual and perceptual cognitive function training materials in the form of mobile mini-games. Experiential activities were conducted for general children and their guardians using the developed contents, and the results were found to be significant in terms of concentration, effect, and effect compared to basic puzzle toys. It is expected that this thesis will be a meaningful data for the study of cognitive function improvement activities based on digital toys and contents.

  • Artificially or naturally contained texts in the natural images have significant and detailed information about the scenes. If we develop a method that can extract and recognize those texts in real-time, the method can be applied to many important applications. In this paper, we suggest a new method that extracts the text areas in the natural images using the low-level image features of color continuity. gray-level variation and color valiance and that verifies the extracted candidate regions by using the high-level text feature such as stroke. And the two level features are combined hierarchically. The color continuity is used since most of the characters in the same text lesion have the same color, and the gray-level variation is used since the text strokes are distinctive in their gray-values to the background. Also, the color variance is used since the text strokes are distinctive in their gray-values to the background, and this value is more sensitive than the gray-level variations. The text level stroke features are extracted using a multi-resolution wavelet transforms on the local image areas and the feature vectors are input to a SVM(Support Vector Machine) classifier for the verification. We have tested the proposed method using various kinds of the natural images and have confirmed that the extraction rates are very high even in complex background images.

  • The purpose of this study is to analyze the transition of glamour style expressed in modern fashion throughout the history. The glamour style in modern fashion was categorized into five periods which are Hollywood glamour(H), Feminine glamour(F), Rich glamour(R), Decadent glamour(D), and Trash glamour(T). These categories were analyzed and compared in the viewpoint of aesthetic values deduced on the previous study. As a method of analysis, literature study and case study through the publications in aesthetics, history and preceding theses were used. The results of analysis are: Ostentatious luxury was suggested by extravagance of the movie star in H, the splendid American lifestyle in F, conspicuous consumption in R, fin de siecle bad taste in D and self-assured exposure in T. Mysterious idolatry was studied as exaggerated goddesshood of the movie star in H. It was expanded to celebrities including fashion models, television actresses, pop singers and young couture designers in the other periods. Artificial sensuality was originated from the femme fatale image of the courtesan as well as the traditional femininity of Victorian era in H. It was developed through exaggerated hourglass silhouette of the wife dressing in F. But an aggressiveness in R, a hyper-sexual femme fatale in D, an independent and defiant image of the showgirl in T were observed. Playful queerness stood out clearly by the fin de siecle phenomena. Though it was embodied in sexual perversive subculture, it emerged as hi fashion by young designers in the late R and became a crucial aesthetic value throughout D and T. It is more connected with the origins of glamour which arouses sexual ambiguity, crudity, aggressiveness and death. The continuity and discontinuity of the glamour style based on the theory of 'linked solution' were also analyzed.

  • Crowded scenes analysis is a challenging topic in computer vision field. How to detect diverse motion patterns in crowded scenarios from videos is the critical yet hard part of this problem. In this paper, we propose a novel approach to mining motion patterns by utilizing motion information during both long-term period and short interval simultaneously. To capture long-term motions effectively, we introduce Motion History Image (MHI) representation to access to the global perspective about the crowd motion. The combination of MHI and optical flow, which is used to get instant motion information, gives rise to discriminative spatial-temporal motion features. Benefitting from the robustness and efficiency of the novel motion representation, the following motion pattern mining is implemented in a completely unsupervised way. The motion vectors are clustered hierarchically through automatic hierarchical clustering algorithm building on the basis of graphic model. This method overcomes the instability of optical flow in dealing with time continuity in crowded scenes. The results of clustering reveal the situations of motion pattern distribution in current crowded videos. To validate the performance of the proposed approach, we conduct experimental evaluations on some challenging videos including vehicles and pedestrians. The reliable detection results demonstrate the effectiveness of our approach.
