This study provides a framework for understanding the effects of brand image(symbolic and functional) on emotional commitment and behavioral commitment. First, the causal relationships between brand image, emotional commitment and behavioral commitment were examined. Second, the mediating effects of brand trust were also examined. Undergraduate students(N=217) were participated in the survey and the structural equation modeling was utilized for data analysis. The results of this study reveal that both of symbolic and functional brand image are positively related to brand trust. Brand trust also have positive effects on emotional commitment and behavioral commitment. Based on the results, some recommendations for company are discussed and future research directions are outlined.

Today, AI image creation technology is being expanded and utilized across industries. Accordingly, various AI image creation programs optimized for the fashion industry are being developed and commercialized. In this study, we compared and analyzed the visual characteristics of fashion images created by AI image creation programs such as Playground, Midjourney, and The New Black to identify the characteristics of each program and point out areas where each program can be used and problems. The results are as follows: First, while Playground and Midjourney intuitively applied the contents of the command to create images that were different from actual fashion trends, Dannew Black created images that were relatively similar to fashion trends. Second, while Playground separates or combines images corresponding to the command content, Midjourny tends to create new images by adding and fusing various details. Third, in Playground, colors not included in the command appear randomly, and in The New Black, colors not included in the command appear coordinated, and Midjourney generates the color specified in the command relatively accurately. In conclusion, Midjourney can be used when seeking inspiration for developing unique and creative fashion designs, and The New Black can be helpful in referencing fashion trends or fashion styling. On the other hand, playgrounds can be somewhat confusing when it comes to color creation, so this is something to be careful about. It is expected that AI image creation tools can be used more efficiently in fashion design development.

In the study of Art History and Archaeology, the paintings, sculptures, relief, and applied arts provide a vivid description of religious and historical events and everyday life. Through these descriptions it is possible to gain a greater understanding of things such as the customs, culture, and architectural styles of that period. However, if Art History and Archaeological images are very old, distorted or underexposed, it is difficult to analyze them. Using Levels and Curves is one way to tonally correct professional photographs. It is an effective method for tonal correction because of the exact numeric values which are calculated and displayed as the image is adjusted. In this paper, the usefulness of this method for correcting a distorted archaeological image was examined.

As the modern techniques have improved, people intend to store and manage the information on the web. Especially, it is the image data that is given a great deal of weight of the information because of the development of the scan and popularization of the digital camera and the cell-phone's camera. However, most image retrieval systems are still based on the text annotations while many images are creating everyday on the web. In this paper, we suggest the new approach for the semantic image retrieval using the RDF metadata based on the representation of the spatial relationships. For the semantic image retrieval, firstly we define the new vocabularies to represent the spatial relationships between the objects in the image. Secondly, we write the metadata about the image using RDF and new vocabularies. Finally. we could expect more correct result in our image retrieval system.

This paper proposes 'postfilimc metamorphosis' and 'reanimation' as two concepts that aim at giving account to the aesthtetic tendencies and genealogies of what Suzanne Buchan calls 'pervasive animation', a category that refers to the unprecedented expansion of animation's formal, technological and experiential boundaries. Buchan's term calls for an interdisciplinary approach to animation by highlighting a range of phenomena that signal the growing embracement of the images and media that transcend the traditional definition of animation, including the lens-based live-action image as the longstanding counterpart of the animation image, and the increasing uses of computer-generated imagery, and the ubiquity of various animated images dispersed across other media and platforms outside the movie theatre. While Buchan's view suggests the impacts of digital technology as a determining factor for opening this interdisciplinary, hybrid fields of 'pervasive animation', I elaborate upon the two concepts in order to argue that the various forms of metamorphorsis and motion found in these fields have their historical roots. That is, 'postfilmic metamorphosis' means that the transformative image in postfimic media such as video and the computer differs from that in traditional celluloid-based animation materially and technically, which demands a refashioned investigation into the history of the 'image-processing' video art which was categorized as experimental animation but largely marginalized. Likewise, 'reanimation' cne be defined as animating the still images (the photographic and the painterly images) or suspending the originally inscribed movement in the moving image and endowing it with a neewly created movement, and both technical procedues, developed in experimental filmmaking and now enabled by a variety of moving image installations in contemporary art, aim at reconsidering the borders between stillness and movement, and between film and photography. By discussing a group of contemporary moving image artworks (including those by Takeshi Murata, David Claerbout, and Ken Jacobs) that present the aesthetic features of 'postfilmic metamorphosis' and 'reanimation' in relation to their precursors, this paper argues that the aesthetic implications of the works that pertain to 'pervasive animation' lie in their challenging the tradition dichotomies of the graphic/the live-action images and stillness/movement. The two concepts, then, respond to a revisionist approach to reconfigure the history and ontology of other media images outside the traditional boundaries of animation as a way of offering a refasioned understanding of 'pervasive animation'.

우리는 본 논문에서 디지털 영상에 대하여 Hash함수를 이용한 내용기반의 안전한 워터마킹 인증기술을 제시하려고 한다. 허가되지 않는 이미지의 내용변경을 막기 위해 안전한 워터마킹 시스템을 개발하기 위하여 비밀키를 가지고 있는 Hash 함수가 사용되었고, 각 블록의 워터마크신호는 Hash함수의 출력결과를 Seed로 사용하여 의사난수를 발생시킨 값에 따라 생성되어진다. 이미지 기술벡터들은 블록기반 에지 이미지로부터 측정되는데 이 값들은 해롭지 않는 조작 등에 대해서는 쉽게 변화하지 않지만 고의적인 내용변경 등의 조작에 대해서는 이들 값들이 바꾸어지는 성질을 갖고 있다. 워터마크신호의 삽입은 블록기반 스펙트럼 방법에 기초를 두고 있으며 워터마크신호의 크기는 인지성과 강인성이 조화를 이루도록 AC 부 밴드의 지그재그 스캔라인의 DCT 계수들의 지역적인 통계량에 따라 조정되어진다. 또한 저작권인증의 확인을 위한 경계 값의 선택은 통계학적으로 분석되어진다. 수치적인 실험의 결과는 제안된 기술이 강력한 저작권인증의 수행을 위해서 매우 효율적인 것을 보여주고 있다.

가상머신을 사용자에게 좀 더 빨리 서비스하기 위해서 서비스 제공자들은 여유 가상머신이나 여유 이미지를 두는 방식을 취해왔으나 이는 근본적인 해결책이 되지는 못했다. 본 논문에서는 가상머신 이미지를 복사하는 시간을 LVM을 이용하여 최소화함으로써 가상머신이 필요한 순간에 필요한 이미지를 이용하여 실시간으로 생성될 수 있도록 설계하였다. 특히 가상머신 이미지의 크기에 무관한 시간이 소요되며 다수의 이미지를 동시에 생성할 시에도 좋은 성능을 보였다.

The purpose of this study is to analyze traditional stereo images (stereopsis), and study electronic methods to create stereo images using computer graphics technology on visualization of computer. Computer system can process image data and show results on its display. In the early days of computer era, most scientific research data was printed on paper as a procession of digits. These days, the visualization of computer graphics has a precise and realistic quality in its imaging technology. Some technological advances have been developed to not only display 2-dimensional geometry but also 3-dimensional stereo images to simulate virtual reality. In this study, [ have discussed the history of stereopsis, principles of stereo images and technological developments. Also I analyzed the components of stereo images, optical and electronic methods and visual systems which are used in computer graphics technology. I developed my own theories on possibilities for new methods of 3-dimensional stereo images.

The purpose of the study was to describe male nursing image and to identify factors influencing the image. We performed an integrative review for a total of 12 studies published between 2009 and 2019. We derived four themes of male nurses' self-image: 1) just a nurse, 2) job opportunity, 3) identity ambiguity, and 4) role limitation. The factors influencing male nurses' self-image were derived from three themes, specifically 1) nursing competency, 2) social gender stereotypes, and 3) absence of male nurse role models. We suggested the need to develop various strategies to enhance male nurses' self-image. Further studies should investigate the public image of male nurses to improve their social role and the perception of them.
