본 논문에서는 ART(Adaptive Resonance Theory) 신경회로망을 이용하여 한글 모음을 인식하고, 그 유형을 분류하는 방법을 제안하였다. 기존의 연구들은 단순히 문자의 선분, 획 등의 정합만을 이용하여 한글의 자소 분류에 중점을 두었다. 그러나 인식 대상 운자의 특성이 각각 다르므로 효율적인 인식을 위해서는 먼저 포괄적인 특정적 유형 분류가 필요하다. 제안된 한글 유형 분류 시스템에서는 먼저 ART 신경회로망의 문제점인 증가분류 알고리즘의 단점을 최소화할 수 있도록 비교층에 최초 활성화패턴의 크기를 기억하는 메모리를 두고 각 층간 하향틀 변화를 경계인수 값을 "1" 이내로 제한하여 이미 입력된 패턴을 다시 입력할 때, 새로운 노드의 활성화를 방지하여 비교적 입력순서에 둔감한 분류가 가능하였다. 실험 결과 제안된 시스템에서는 한글의 6형식 중 1, 3, 4, 5형식 분류는 평균 97.3% 의 분류율을 보였으나, 나머지 2, 6형식 분류는 다소 떨어지는 평균 94.9% 분류율를 보였다.

In this research, we study the problem of font image skeletonization using an end-to-end deep adversarial network, in contrast with the state-of-the-art methods that use mathematical algorithms. Several studies have been concerned with skeletonization, but a few have utilized deep learning. Further, no study has considered generative models based on deep neural networks for font character skeletonization, which are more delicate than natural objects. In this work, we take a step closer to producing realistic synthesized skeletons of font characters. We consider using an end-to-end deep adversarial network, SkelGAN, for font-image skeletonization, in contrast with the state-of-the-art methods that use mathematical algorithms. The proposed skeleton generator is proved superior to all well-known mathematical skeletonization methods in terms of character structure, including delicate strokes, serifs, and even special styles. Experimental results also demonstrate the dominance of our method against the state-of-the-art supervised image-to-image translation method in font character skeletonization task.

Contemporary Chinese "micro-perspective" painting is an artistic phenomenon that we cannot ignore. It is the young artists who focus on themselves and their communities, record their stories and emotions in their life fragments into the coming history, and diary paintings as "micro-perspective" paintings allow "marginal people" to find their place. Based on the analysis of the aesthetic form and aesthetic characteristics of Chinese contemporary art, this paper explores the three aesthetic dimensions and their inherent aesthetic value, and explains its significance from the perspective of "micro-view" aesthetics. In the contemporary context, "micro-perspective" painting has become a unique cultural phenomenon, a consciousness situation. However, this phenomenon has a very unique artistic value and cultural value for the youth art group and even the formation of aesthetic culture and zeitgeist in China's current society.

Prior art search is a core process of technology management performed by inventors and applicants, patent examiners, and employees in the patent industry. As a result of insufficient academic research on a systematic prior art search methodology, the process has been often carried out depending on the subjective judgment of researchers. Previous studies on exploring prior arts based on semantics have also have the risk of underestimating the similarity of major prior arts due to the nature of patent documents where the same technical ideas are expressed in various terms. In this study, we propose an effective prior art search methodology based on hierarchical citation analysis, which provides a clear criterion for selecting core prior arts by calculating weights according to the relative importance of the collected patents. In order to verify the feasibility of the proposed methodology, a case study was conducted to explore the core prior art of one patent in the display field. As a result, 10 core prior art candidates were selected out of the 206 precedent patents.

The purpose of this study is to evaluate efficacy and feasibility of adaptive radiotherapy according to tumor volume change (TVC) in early stage non-small cell lung cancer (NSCLC) using stereotactic body radiotherapy (SBRT). Twenty-two lesions previously treated with SBRT were selected. SBRT was usually performed with a total dose of 48 Gy or 60 Gy in four fractions with an interval of three to four days between treatments. For evaluation of TVC, gross tumor volume (GTV) was contoured on each cone-beam computed tomography (CBCT) image used for image guidance. Intensity modulated radiotherapy (IMRT) planning was performed in the first CBCT (CBCT1) using a baseline plan. For ART planning (ART), re-optimization was performed at $2^{nd}$, $3^{rd}$, and $4^{th}$ CBCTs (CBCT2, CBCT3, and CBCT4) using the same angle and constraint used for the baseline plan. The ART plan was compared with the non-ART plan, which generated copying of the baseline plan to other CBCTs. Average GTV volume was 10.7 cc. Average TVC was -1.5%, 7.3%, and -25.1% in CBCT2, CBCT3, and CBCT4 and the TVC after CBCT3 was significant (p<0.05). However, the nine lesions were increased GTV in CBCT2. In the ART plan, $V_{20\;Gy}$, $D_{1500\;cc}$, and $D_{1000\;cc}$ of lung were significantly decreased (p<0.05), and $V_{30\;Gy}$ and $V_{32\;Gy}$ of the chest wall were also decreased (p<0.05). While D min of planning target volume (PTV) decreased by 8.3% in the non-ART plan of CBCT2 compared with the baseline plan in lesions with increased tumor size (p=0.021), PTV coverage was not compromised in the ART plan. Based on this result, use of the ART plan may improve target coverage and OAR saving. Thus ART using CBCT should be considered in early stage NSCLC with SBRT.

This paper proposes an efficient recognition method of car license plate from the car images by using both the dynamical thresholding and the neural network with enhanced learning algorithm. The car license plate is extracted by the dynamical thresholding based on the structural features and the density rates. Each characters and numbers from the p]ate is also extracted by the contour tracking algorithm. The enhanced neural network is proposed for recognizing them, which has the algorithm of combining the modified ART1 and the supervised learning method. The proposed method has applied to the real-world car images. The simulation results show that the proposed method has better the extraction rates than the methods with information of the gray brightness and the RGB, respectively. And the proposed method has better recognition performance than the conventional backpropagation neural network.

The purpose of this study is to pursue the way of human body expression for prospecting of future fashion illustration through research of the methods and meaning expressed in the works of 30 years by Antonio Lopez. The research was conducted by looking into the perception of the body between 1960s and 1980s, when Lopez worked actively, on the basis of the discourse, art and fashion for the femininity and studying the representation method and meaning of the body in his works. Lopez suggested an index of the ideal beauty of the times through the representation of the immature body like a child in the 60s, the glamorous body in the 70s and the exaggerated muscular body in the 80s by predicting the changes of the perception of femininity and ideal beauty. As the result of this research, it is found that Lopez employed the art form for the representation of the body in his works and presented the polysemous implications of the art form in the context of the body expression. In addition, he redefined sexuality by focusing on the code that confronted the conventional women's morals by changing the representation method of the women's pose, and depicted the other's image such as the colored races, departing from the ideal human body based on the white women. Lastly, he deconstructed the human body in various ways, thereby enlarging the concept of the human body in the existing fashion illustration.

This study aims to analyze typographic expressions used in recent fashion trends from the perspective of conceptual art and thus identify a variety of meanings. Towards this end, theoretical considerations were made vis-à-vis the main concepts of research, such as typography and conceptual art, and the ready-made, documentation, intervention and language, which are the expressive features of conceptual art, were applied to fashion typography as analytical frameworks. The results are as follows. The ready-made appears in a way that borrows or transforms the visual identity of other brands, and documentation is utilized in a way that lays tautological or contradictory texts together. Intervention arises, while leading to more complex layers of meaning when borrowing the visual identity of the brand, which is conceptually irrelevant. The language is expressed as statements about contemporary social issues, such as environmental protection, ethical consumption and gender problems. Based on the findings of this study, it can be confirmed that in fashion design, typography serves as an effective marketing tool and a medium of social statements. Moreover, it can expand into the possibility of generating new meanings as a novel way of visual expression.
