직물의 외관 품위는 직물의 촉각뿐만 아니라 시각적인 자극에 의해서 크게 결정된다. 견직물이나 양모직물의 광택 등 자연스러운 광학적 특성은 특히 구성 섬유의 특성이나 구성사의 구조, 직물 조직 등과 밀접한 관계가 있는데 그 중 섬유단면형태가 가장 중요한 인자라고 할 수 있다. 따라서 단면형상에 따른 직물의 외관 감성 특히 시각특성에 미치는 영향을 알아보기 위하여 직물의 광택도를 측정하였다. 그 결과 섬유 단면의 요철이 많으면 광택도가 감소하면 섬유단면이 매끈한 부분이 많은 섬유는 광택도가 증가하였다. 그러나 이섬도 혼섬단면사로 구성된 직물은 광택이 우수하면서 은은함을 부여해주었다.

The purpose of this study is to propose the direction for identification of artistically gifted children by considering the methods of it as a part of the basic study for artistically gifted children education. The result of study on the identification of artistically gifted children in literature, the identification methods are classified into the formal standardized art test, the informal test, and non-test measure. And they are considered and discussed laying importance on their characteristics and problems.

본 논문에서는 인간시각시스템(HVS)과 블록 DCT를 이용한 효과적인 워터마킹 방법을 제안한다. 워터마크는 시각적으로 인식 가능한 패턴과 비밀키에 의해 생성되고, 인간시각특성에 따라 영상의 중간 주파수 대역을 선택적으로 변조함으로서 삽입된다. 워터마크의 추출에는 원 영상이 필요하며, 추출된 워터마크와 원래의 워터마크와의 상관관계를 통하여 유사성을 판별한다. 제안한 방법의 실험결과, 영상에 삽입된 워터마크는 노이즈, 필터링, JPEG 손실압축등에 강인함을 보여준다.

The purpose of this study is to investigate characteristics of hydromorpological structures that affect landscape preference and visual characteristics on the sections of the designated streams where have dynamic ecological characteristics. We evaluated the ecological status of the streams utilizing LAWA to assess hydromorpological structures of streams. We also investigated preference and visual characteristics of stream landscapes through Semantic Differential Scale(SD scale). The differences of visual images according to the characteristics of hydromorpological structures in the sites were analyzed by descriptive statistics, One-way ANOVA, and t-test. As a result, this study showed that sections represented as "good" ecological status are shown to be harmonious, beautiful, natural, and clean comparing to sections represented as "poor" ecological status. The hydromorpological structures that have significant impacts on the visual characteristics are considered as riparian vegetation, cross-sectional shape, and the artificial structures. Results of this study can help guide the stream restoration of the damaged stream to improving ecological function and positive landscape.

Visual tactility implies feelings of touch through sight. To be exact, the eyes are doing the touch rather than the body and the subject concerned will experience the sensation of touch by looking at an object similar to that of physical touch. This is quasi tactility to put it simply and it can be defined as to touch with the eyes. This can not only provide opportunities to experience something close to reality but also another completely different form of modern experience. Experiencing visual tactility through the use of the web permits lavish communication between the user and the designer. This paper has reorganize the concept of visual tactility, characteristic and way to use in digital contents. Visual tactility stimulates the users' emotion as such. If it was to be utilized to develop edutainment contents or web sites will foster children's capability to develope problem solving skills and raise efficiency in creative learning, and prolong the period of concentration in order to encourage revisits to the place and extend the time of stay.

A scientific and systematic approach for digitally representing colours is essential for improving image quality. Therefore, there is a need for objectively analysing such approaches. Studies regarding display systems, which can reflect human visual characteristics in the digital media environment, and associated international standards at the forefront, have already caused significant impact. Colour is one of the most important factors employed for evaluating the overall image quality of displays. The proposed study focusses on colour properties which are based on the characteristics of the human peripheral vision area, with the primary objective of reproducing digital colours which can simulate human visual characteristics in the digital media environment. The proposed study aims at identifying digital colour characteristics which can vary according to the level of background lightness and the size of colour stimuli. Based on the evaluation results obtained through psychophysical experiments, a method has been proposed for determining peripheral vision characteristics which vary according to the increasing size of a colour stimulus, thereby digitally reproducing them on displays.

In this study, we contemplated types, essence, characteristics of text data which is material for visual expression of text visualization part of data visualization research and also analysed the multidirectional means of expressive approach for it. Studies of text visualization are spread dramastically under the influence of computer development, open data, wide use of visualization tools, etc. For these reasons, text visualization works have been creating as art works or output of research through various inter-discipline convergent research with engineering, art, humanities, sociology, etc. Nevertheless the theoretical studies on text data itself and its visualization, and also systematic analysis of its approach are rarely made. Data is target of understanding and interpretation, and it has infinite information and possibility with process and approach for it. Considering the attainable status of data in future human society, text visualization which is convergent academic field of study starting with understanding and interpretation of data needs further methodological research and theoretical accumulate.

Designer creates new design alternatives using acquisition of visual information in design process. Which is more effectiveness to acquire in directive visual information or in-directive visual information\ulcorner In this research we would like to find out that the relation of character in visual information and design alternatives. So to A subjects, we give them to see directive visual information to make visual mental imagery, to B subjects, we give them to see in-directive visual information to make it. In this experiment they must crate telephone design. C subjects must evaluate this design alternatives by questions composing scale in distinction and elegant. After a experimentation, It is true that we make hypothesis that distinct two subjects in distinction and elegant. Though elegant is opposite with hypothesis. So to make elegant design. it is import to concentrate cognitive ability. Accordingly it proves that in-directive visual information is effective for new type design stage in design process and directive visual information is effective for new style design stage in design process.

People are surrounded with numerous sounds. The sound is generated from nature and people. For example, the sound enables people or animal responsive to instinctive action. Music or fine arts are presented differently by its distinctive medium. On the other hand, those art forms are similar in a way that people uses right side of brain and intuitions for creative effects. Conjunctions between sounds and visual arts have been progressed to data. From art forms in subjective views to art forms using high technology such as the computer, experiments for sounds visualization are practiced constantly. For that reason, intrinsic attributes of sounds in design area and distinctive qualities are discussed in this study. With respect to existing category of studies and consideration of the tendency in recent researches, the object is to propose direction for the study in regards to methodology of design, which is reconstructing visualized expression.

애니메이션의 사전제작과정에서 캐릭터의 보다 효율적 제작, 분석, 평가을 위해 시각적 모델화및 데이터 베이스 구축이 필요했다. 캐릭터의 체격과 기질 관계를 조명하기 위해 W. 셀던의 체격기질유형 이론으로부터 정형화된 분석 틀을 구축하여 개념을 시각화하고 유형분석 모델을 만들었으며, 또한 케이스 스터디를 위해 세 애니메이션에 나타난 캐릭터의 유형들을 분석함으로써 모델의 적용 가능성과 나아가 애니메이션의 캐릭터에서 표현된 외적 형상과 내적 기질의 상관성을 추론하여 실제 적용이 가능한 기초적 데이터가 되도록 하였다.
