본 논문에서는 시간의 축에 따라 점진적으로 확산되는 정보 네트워크를 효과적으로 표현할 수 있는 시각화 도구를 소개하고자 한다. 이것은 기존의 정적인 데이터에 대한 정적인 시각화 결과물을 제시하는 시각화 도구들과는 달리, 시간의 축에 따라 동적으로 성장하는 데이터를 효과적으로 표현할 수 있다는데 그 차이가 있다. 이를 위해 그래프 기반의 정보 확산 네트워크 모델을 정의 하고, 이 그래프에 시간의 축에 따른 데이터의 성장을 반영하여, 정보 확산 과정을 시각화 할 수 있는 도구를 제작하였다. 결론적으로, 본 논문에서 제시하는 도구는 시간의 축에 따라 점진적으로 성장하는 정보 네트워크의 성장 과정을 시각화함으로 해서, 복잡하게 엉켜 있는 정보들이 어떻게 확산되며, 어떤 모양으로 생겼는지, 또 어떻게 진화하는가에 대한 시각적 재현을 통해 정보 확산 네트워크의 속성을 이해하는데 도움을 줄 수 있는 새로운 시각화 도구를 제시했다는데 그 의미가 있다.

시트콤 동염상은 고정된 배경을 갖는 중 아웃에 연이어 오는 줌 인으로 구성되어 있고, 또한 활영되는 배경의 수는 한정되어 있는 특성이 때문에, 이러한 배경의 시각적 특성을 사용하여 배경들을 학습시키고 자동으로 분리시킬 수 있다. 본 논문에서는 신경망의 일종인 LVQ[1]를 사용하여 이러한 증류의 비디오 동영상에 대한 자동 배경 분류 방법을 제안한다. 우선, MPEG-7 시각 기술자를 이용하여 신(scene) 배경의 시각적인 특성을 추출하고 이러한 시각적 특성을 미리 제작자에 의해서 주어진 배경 점보로서 LVQ를 학습시킨다. 학습이 진행되면서 특정 배경의 시각적 특성은 LVQ의 가중치로서 표현되며, 다른 배경을 자동으로 분류하는데 사용된다 제안된 LVQ기반의 분류 방법을 사용한 두 종류의 시트콤 동영상에 대한 실험 결과는 분류에 대한 어떠한 하드코딩 없이 80-90%의 정확도로 시트콤 동영상의 배경을 자동으로 분류한다.

As software industry progresses, the necessity of visual information have increased more than text-oriented information. So, automatic tools are required to satisfy a user's desire for visual design representation of various source information in the real-world. In this paper, we discuss the methodology and tools for parsing abstract information through semantic analysis and extracting visual information through visual mapping. Namely, as to abstract informations are represented as relational structure and then mapped into visual structure using regular rule, user can obtain visual information. We suggest VOLS(Visual Object Layout System) to transform a abstract information to visual information. It can improve user understandability and assist a maintenance for existing source code.

The purpose of this study was to clarify the effects of constituent characteristics and the mechanical properties by KES-FB system on the visual texture images and preference of men's suit fabrics. Twenty different kinds of black fabrics, which were used mainly for the spring and summer men's suits, were selected and the subjective evaluation of the visual texture images was tested. Sixty experts in department of clothing and apparel industries participated in the subjective evaluation. Factor analysis showed visual texture images were classified into 4 categories : 'bulkiness', $'extensibility{\cdot}rapability'$, 'flexibility' and 'smoothness'. All of relationships were established between the mechanical properties and the visual texture images except the relation between 'flexibility' and bending properties. The significant factors affecting preference were 'smoothness', compression energy(WC), fabric count and 'flexibility', As the fabrics had higher value for 'smoothness' and 'flexibility' , and lower ones for compression energy and fabric count, they tended to be more preferred.

This study was conducted to analyze the Korean inclination to visual equivocality. Similar studies conducted by several psychologists were reviewed in order to determine whether we can put equal value on the visual equivocality which is often shown in natural appearance. This Korean inclination was also investigated with the help of a public survey. The following conclusions were derived from the study. - In reality, there is no visual equivocality for Koreans except in some specific cases. - It is true that, on a screen, a diagonal line from the lower right to the upper left produces a stronger feeling of upward tendency than one from the lower left to the upper right. - The idea that the right side of a screen looks heavier than the left one was not supported and should be rejected for Koreans. - It was discovered that the user interface is working when a person is describing a natural appearance or looking at a description. This fact is generally accepted for Koreans, the majority of whom are right-handed. - Until now, the idea of a Korean superiority toward the left side in visual expression has been found in our culture. In short, it was uncovered that Korean people generally do not have visual equivocality but, instead, have an inclination to left side rather than the right from various aspects.

This study is to exhibit the iconographic narrative and visual culture of ancient Chinese art. The focus of the study is the composite integration of literature and graphic forms, in particular the heterochronous expression of different scenarios of scenes occurring in different time periods in pictures of ancient art. The unity of their origins with picture narration and comic art creation is the fusion of our modern times. The ancient Chinese understanding of visual art includes the traditional style of images and their symbolic meanings. Among artistic narrative expression, imagery contemplation and visual presentation have significance. Artistic thinking is inseparable from visual articulation. It is a rational thought process through creative language interpretation in visual media of imagery narratives. The characteristics of ancient imagery thinking and the way of presenting sequential incidents in the form pictures is a creative space of time. This is the spatial thinking of modern comic art, which is demonstrated through acceptance in artistic styles. Image narration needs new forms and media styles, including integrating with cultural values as aesthetic communication is necessary.

The English Landscape garden and picturesque aesthetics, which was in fashion during the 18th to early 19th century in England, has been accused of making people see the actual garden in terms of a static landscape painting without a synesthetic engagement in nature. As new optic devices such as diorama, panorama, photography, and cinematography were invented, ways of seeing nature transitioned from a perspective vision to a panoramic, that is, modern one. This study intends to uncover signs of this kind of modern vision in the picturesque aesthetics and visual representation of landscape gardener Humphry Repton. German garden theorist Christian Cay Lorenz Hirschfeld contended that the English landscape garden was a new style of designing landscape that followed the principle of the serpentine line, which produced movement in sightlines; thus, he considered garden art as a superior art form among all other genres. The signs of visual motion appear in Repton's sketches of "Red Books". Firstly, he designed systemic routes in his clients' properties by considering different types of movements between walks and drives. Secondly, he often used the visual effects of panoramic views for his sketches in order to allow his clients to experience the human visual field. Lastly, he constructed sequences of sketches in order to provide his clients with an illusion of movement; in other words, Repton's sketches functioned as potential visual media to produce the duration of time in a visual experience. Thus, the garden aesthetics of the time reflected the contemporary visual culture, that is to say, a panoramic vision pertaining to visual motion.

This paper proposes a novel bit allocation algorithm for H.264 scalable extension(SE) based on a human visual system (HVS) to improve the coding efficiency. The proposed algorithm is consist of two stages: visual weighting model and visual weighting-based bit allocation algorithm. In the first stage, the visual weighting for each macroblock (MB) is analyzed according to the region of interests. Then the adaptation of the visual weighting into the bit allocation routine for each quality layer is performed for improving the visual quality. In the simulation results, it is observed that the proposed scheme can improve the subjective and objective video quality in the same bit rate, compared to the previous scalable video coding in H.264.

In this paper, we suggest a visual language supporting collaboration with functional attributes. The visual language is a set of visual sentences that consist of object icons and operators. The object icon is a user who participates in collaboration. And, the operator means interactive relations between users according to a point of collaborative time. The functional attributes that support various computing orders provide flexibility of interactive relations on collaboration. Also, using representation both synchronous and asynchronous relations in collaboration, the visual language supports efficiently collaboration than conventional visual languages. And, functional attributes of visual sentences are analyzed using $\lambda$ expressions.
