People are exposed to various media. After the Digital Revolution, quantitative expansion of the media is at a rapid pace. Because of the expansion of the media, advertising needs efforts that induce the audiences' reaction. Rhetorical devices are used as the efforts. This study noted the visual paradox of rhetorical devices because it is an effective representation device that induced audiences' reaction by deliberate contradiction and ambiguity. This study has defined the visual paradox based on define and classification of paradox in logic. This study also tried to reveal the relationship between images and text for signification by metalanguage because it is important to the visual paradox in advertising. And analyzed cases of Volkswagen ads to prove the research process. Finally identified that images and text interact to create a new meaning.

Network attack analysis and visualization methods using network traffic session data detect network anomalies by visualizing the sender's and receiver's IP addresses and the relationship between them. The traffic flow is a critical feature in detecting anomalies, but simply visualizing the source and destination IP addresses symmetrically from up-down or left-right would become a problematic factor for the analysis. Also, there is a risk of losing timely security situation when designing a visualization interface without considering the temporal characteristics of time-series traffic sessions. In this paper, we propose a visualization interface and analysis method that visualizes time-series traffic data by using the radial axis, divide IP addresses into network and host portions which then projects on the cylindrical coordinate system that could effectively monitor network attacks. The proposed method has the advantage of intuitively recognizing network attacks and identifying attack activity over time.

One of the reasons behind the surfacing of such issues is because the record does not exist and even if the records remained, it is because they are not being properly managed. In Korea, National institutions in the field of visual arts, currently there are no archives that manage only the records for the visual arts as an independent institution, and the reality is that the National Museum of Archives is still in the beginning stage as well. This study has conducted a research on the records collection strategy and the management of the record information of an author who is the creator of the visual arts as a starting point of the visual arts. For this purpose, the definition of visual arts and the concept of an author covered in this study will be examined and the types of documentary that may occur in the field of visual arts were analyzed. In addition, the history of an author is its personal record thus a personal history and private archive have been examined. Based on this background, the cases on the personal record and the management of the record information of domestic and foreign authors were analyzed and the implications were derived.

Music Braille is essential and academic materials for the blind to learn and enjoy music. In Korea, National Library for the Disabled is the public institution for the manufacture digital music braille by the request and the center of music rehabilitation the disabled also make the digital music braille on a welfare level. However, most of braille libraries in Korea do have little music braille compared to other braille books. This paper reports the current situations how braille libraries including National library for the Disabled contain braille books, music brailles and digital music brailles to find out that the blinds can be provided exact informations about music brailles and digital music brailles so they can learn music with the right materials such as music brailles. In conclusion, the construction of Database for the digital music brailles is required and necessary for the blind to have better activities of music from the welfare and artistic point of view.

서로 다른 공간해상도와 분광해상도를 가진 영상들을 이용하여 영상지도를 제작할 때 공간해상도를 향상시킬 수 있는 영상융합기법에 대해 연구하였다. 사용된 영상은 IKONOS panchromatic 영상과 multispectral 위성영상, KOMPSAT-1호 위성영상과 SPOT XS 위성영상에 대해 Brovey, IHS, PCA, HPF, CN, MWD 융합기법을 적용하여 시각적 분석, 공간정보의 분포특성, 통계적 특성을 기준으로 분석하였으며, 시각적 분석에서는 IHS, PCA 융합기법이, 통계적 분석에서는 HPF, MWD 융합기법이 좋은 결과를 보여주었으며, 종합적인 결과분석을 고려할 때 MWD 융합기법이 원 영상의 분광정보를 가장 작게 왜곡시킴을 알 수 있었다.

내용기반 이미지 검색을 하기 위해서는 이미지에 대한 내용정보가 필요하며, 이러한 내용정보간에는 상호 연관성이 존재한다. XML(eXtensible Markup Language)은 내용정보간의 상호연관성을 표현하기에 적절하므로 본 논문에서는 이미지 내용정보를 구조화하기 위한 방법으로 XML을 사용하였다. 또한 이미지는 눈에 보이는 객체의 시각적인 특징과 이미지 전테가 내포하는 시술적인 의미도 가지므로, 이러한 이미지의 특성에 따라 내용정보의 구조도 객체의 시각적 특징 중심의 모델링과 의미 중심의 모델링으로 구분하여 XML 문서 구조를 모델링 하였다. 구조화된 모델들 간의 객체지향 특성을 이용하여 XML 데이터 서버인 eXcelon에 통합하고, 이를 XQL(XML Query Language)에 의하여 질의해 냄으로써 검색 구간에 제약을 가하고 이를 통하여 더욱 효과적인 검색을 지원하도록 한다. 검색되어진 XML 문서 구조는 XSL(extensible StyleSheets Language)의 적용을 통하여 쉬운 형태로 웹 브라우저 상에 출력하도록 한다. 마지막으로 본 논문에서 제안한 모댈링의 효율성을 검증하기 위하여, 웹 상에서 이미지 내용정보의 상호 연관성에 기반 하여 원하는 이미지를 검색할 수 있는 시스템을 구현하였다.

본 논문은 그레이 스케일 인쇄 영상의 저작권을 보호할 수 있는 워터마킹 기법에 관한 연구이다. 기존의 인쇄영상 워터마크 기법 연구는 디더링을 이용하는 까닭에 인쇄 영상의 화질 감소가 발생한다. 본 연구에서는 HVS(human visual system)의 특성을 이용하여 시각적으로 감지할 수 없는 워터마크를 영상 내에 삽입한다. 제안된 알고리즘은 메쉬 블록을 사용하여 그레이 스케일 영상에 워터마크를 삽입하므로 영상의 시각적인 화질 감소가 없을 뿐만 아니라, 프린터와 스캐너에 의한 영상의 기하학적 변형에도 워터마크의 삽입과 추출이 가능하다. 제안된 알고리즘으로 워터마킹하는 경우, 잘라내기(cropping), 회전(rotation), 그리고 스캐너와 프린터의 기기적인 특성에도 강한 워터마크를 삽입하고 추출할 수 있다. 제안된 알고리즘으로 인쇄 영상에 워터마크를 삽입하고 추출하는 실험 결과들은 인쇄 원영상의 화질을 손상하지 않고 기하학적 변형에도 강한 워터마크의 삽입과 추출이 가능함을 보여준다.

CIELAB coordinate is represented by one lightness component and two chromaticity components and similar to human visual system. Visual devices such as computer monitor display images using RGB coordinate. We propose a technique for inserting the watermark of visually recognizable mark into the middle frequency domain of image. RGB coordinate image is transformed into CIELAB coordinate, which include the characteristics of Human vision and then a* component is transformed into DFT(Discrete Fourier transform) transform.

The object of this research is to understand the domain-universality and domain-specificity of scientific domain and visual art domain from case studies on individuals who had made creative accomplishments in the domain of science and visual art. For case studies, 10 people who made creative accomplishments in the science and technology domain and 9 people who made creative accomplishments in the visual art domain were selected as the research participants. The conclusions for the case studies were made on the data obtained from interviewing the research participants using KES as an analytical frame. The findings of this study support as follows. Creativity on scientific domain and visual art domain is both the domain-universality and domain-Specificity. The domain-universality Of scientific domain and visual art domain is related to the nature of human beings, originality in creativity, and the natural selection. On the other hand, The domain-specificity of scientific domain and visual art domain is related to the type of knowledge and the context of applying the knowledge, will, thinking skill, direction, and social components.
