Recently, rapidly increa~ing internet Websites are providing us with the new kinds of multimedia infonnations without borders acting as the center for exchanging informations. Such new media infonnations through the internet passes infonnations via light on the monitor and provides the various infonnations, with the differentiation from the traditional printing media, it can be searched with electronic commands in limited space. In the process of adapting the new technologies, new media has successfully responded to the fast change and the development of its needs by experiencing the trials and errors, steadily establishing the stable position with its new infonnation transferring and exchanging methods. The representative hompage of websites of information lransfonnations means the first page containing no lower directories and consist of titles, icons, symbols and addresses and can design them in consideration of graphical process, planning, contents and others. Such hompages are very important since the graphical images shows its visual expressions deciding the total meanings of the hompages. In this research, we have analyzed the relationships between its overall colors and text colors from randomly picked hompages of websites in the internets of various areas. Generally, the homepages are designed with graphical expressions in personal way and the feedbacks and responses of such may differs, but this can be used as reference materials for the analysis of new media in objective way. Also, it can be used as the base informations for arrangement and planning of designs with the characteristics of graphics and Graphical User Intertilces in the backhlfound which are implemented over internet.

The purpose of this study was to examine music-color association response(MCAR) of people with visual impairment through music-emotion scale and music-color scale. The study was conducted on 60 participants(30 congenital/ 30 adventitious) who are using services of two welfare centers at S and B cities. For this, four basic emotions (happiness, sadness, anger, and fear) mediated by music were selected, and MCAR to emotion-inducing music were analyzed through self-report method. As a result, first, there were found contrasts in MCAR between happiness and sadness according to type of emotion, however, similar in anger and fear. Second, in MCAR among three variables of the music-emotion scale(valence, arousal and intensity), valence was congruent with MCAR according to type of emotion, arousal marked high scores in negative emotions, and scores of intensity in happiness and sadness were higher than those in anger and fear. Third, there were no significant differences between two groups of people with congenital and adventitious visual impairments. It is meaningful that this study showed the MCAR can be mediated by music through investigating those of people with visual impairment.

The purpose of this study was to investigate the changes in properties of silk fabrics dyed with safflower red and yellow colorants under Ultraviolet(UV)-light. Silk fabrics dyed with safflower red and yellow colorants were compared with each other after uv-light exposure in terms of K/S value, color changes(${\Delta}E$), morphology, and strength retention. The K/S value rapidly decreased with increasing exposure time for samples of both colorants, but the extent of decrease was less for the samples dyed with safflower yellow colorant, than that of the samples dyed with safflower red colorant. Regarding the color changes with increasing exposure time, $L^*$ and $b^*$ increased, $a^*$ decreased, and thereby ${\Delta}E$ increased in the red-dyed samples, whereas $L^*$ increased, $a^*$ and $b^*$ decreased, and so ${\Delta}E$ increased in the yellow-dyed samples, indicating that the UV-light induced fading and changes of hue, value and chroma value. However, the color change of the yellow-dyed samples was less than that of the red-dyed samples. SEM images showed a severe degradation by UV-exposure for both colorant samples. Tensile strength slowly decreased until 14 days, but rapidly decreased thereafter. Strength retention of the yellow-dyed samples was higher than that of red-dyed samples.

The purpose of this study is to build user's psychological response process model on design evaluation. Users firstly evaluate design factors such as form, structure, texture and colors which are basic elements of product design. These factors, however are affected by product's situational factors, user's individual factors and environmental factors. That is, even same design can be evaluated differently by users according to product's situational factors such as price level, brand prestige level and marketing programs, and user's individual factors such as tastes, involvement level, personality, lifestyles and demographics, and environmental factors such as culture, sub-culture, social class, reference group and family and so on. Understanding how users evaluate product design is necessary to increase the possibility to create user-preferring design and also is the starting point of user-based design and design marketing. In the future researches, it is necessary to examine more factors which are not included in the study and to find out the relationship between factors affecting user's evaluation on design and user's psychological response.

특정 대상 또는 외부 자극에 대해 반사적이고 직관적으로 발생하는 느낌으로 정의되는 감성은 자신의 경험을 바탕으로 개개인이 서로 다른 반응을 보이는 특징을 가진다. 이러한 감성은 맞춤형, 적응형 및 개인화된 서비스를 요구하는 현대사회에서 반드시 필요하고 연구되어야 하는 대상이다. 하지만, 감성은 외부 자극에 따라 빠르게 변하고 객관성을 유지하기 어려울 뿐 아니라 복합적으로 나타나기 때문에 측정하거나 표현하기가 매우 어렵다. 시각정보는 감성을 이해하고 전달하는 데 큰 비중을 차지하며, 대상에 대한 종합적인 정보를 전달하여 빠르게 인지하고 이해하는데 많은 도움을 준다. 그 중 색채정보는 대상의 객관적인 특정, 심리적 속성 및 사회적 배경을 반영할 수 있어 복합적인 감성을 효과적으로 표현하고 전달한다. 많은 연구를 통해 감성과 색채정보 간의 관계를 생성하고 정의하였지만, 단일 시각정보로 감성을 표현하는 것은 한계가 있다. 본 논문에서는 종합적인 시각정보를 고려한 감성연구를 제안하기 위해 대용량의 감성어휘와 이미지를 수집하였다. 감성어휘는 The Center for the Study of Emotion and Attention(CSEA)에서 생성한 균형 감성어휘 중 273개를 사용하였고 감성이미지는 객관성과 공통성을 유지하기 위해 사용자의 참여가 활발하고 이미지에 부착된 태그가 비교적 정확한 Flickr를 사용하여 수집하였다. 감성어휘 당 약 500개의 이미지를 수집하고자 시도하였고, 총 130,944개의 감성이미지 후보를 수집하였다. 한 번 수집된 이미지는 중복을 피하였고, JPEG형식으로 저장되어 있다. 또한, 각 이미지에는 사용자 태그가 평균적으로 약 25개가 포함되어 있고, 총 2,l47,645개의 태그를 수집하였다.

Companies and brands that practice sustainability pay attention to New Media due to its ability to build a sustainable relationship between companies and consumers. The need for research on specific roles, characteristics, and social media effects on eco-friendly advertising has had rapid growth in marketing programs for sustainable activities especially shown through social media. Information about sustainable fashion has spread to consumers through social media, and multifarious efforts have been made to attract the attention of youth. Despite the dramatic increase in eco-friendly marketing through social media as a part of sustainability, there is a lack of research on the major influences of emotional factors such as ad color and expression in social media. In this context, it is meaningful to identify relationships between emotional responses, advertising value and consumer behavior of sustainable fashion brands in Instagram and implement a suitable advertising type (color vs expression) for consumers. We used 366 responses for the final analysis. Data were analyzed by factor analysis, structural equation modeling using SPSS 18.0 and AMOS 18.0. The results of this study suggest that emotional responses, advertising value have a significant effect on the flow. This study expands on a previously limited research field by verifying consumer responses to image advertising on Instagram, rather than general sustainable fashion marketing. The study results also provide meaningful implications for a relation formation between customers and fashion brands vis-${\grave{a}}$-vis sustainable social media marketing.

Increasing the needs for eco-friendly natural materials, much attention on natural dyes has been attracted. Curcumin, one of abundant natural dyes available in nature, is an eco-friendly molecule found in turmeric. In this study, the colorimetric sensing behavior characteristics of ammonia and hydrogen chloride gases was analyzed using curcumin ink-printed paper and cotton fabric by inkjet printing method. The fabricated paper and fabric were utilized as a colorimetric sensor that can track food spoilage. The color changes of the samples printed on the paper and cotton upon exposure to the toxic gases, the reversibility of the color changes, and the water resistance were investigated. Both samples showed reversible reactions with NH3 and HCl, and small amount of ammonia produced by food spoilage was successfully sensed with naked eyes, confirming its capability to warn food spoilage in our daily life.
