  • Mobile display panel is small so that users are often difficult to perceive images clearly. About image we perceive much through colors and therefore we propose color fitting approach for clear perception even on the small and low quality LCD panels. Various color modifications have been studied and used in commercial software packages. For mobile usage, our approach instantly enhances color images by modifying colors in a way to contrast differences of them. The method includes tone enhancements (which contrast dark and bright sides) and color enhancements (which reduce saturation for pure colorants). Based on color theory, our method also modifies color values towards specified complementary and preference colors. We term this color fitting. This approach enables displaying photos, multimedia messages, videos and digital media broadcasting (DMB) for better perception in real-time on mobile devices. Index Terms.) color fitting, visualization on small display, mobile graphics, visual perception.

  • Colour properties can be classified based on hue, brightness, and saturation, and the characteristics of colour perception vary by colour property. In terms of colour perception, surrounding colours are viewed together rather than independently, and the characteristics of the original colour perception may vary depending on the colour characteristics of the surrounding. Thus far, research on colour perception and sensibility has focused on a monotonic environment, which is different from colour perception in real life. As such, a fundamental study on colour perception considering surrounding colours must be conducted. In this study, a psychophysical experiment was conducted, and the results were analysed to study the colour perception characteristics by edge brightness, Edge brightness was set as a variable based on the visual traits that are most sensitive to brightness, and the experiment was conducted using the Munsell colour system to specify the stimulus colour. Based on the analysis of the experimental outcomes, this study reveals the significance of fundamental research data on the visual and perceptual characteristics of colour perception with regard to edge brightness and provides directions for future research.

  • COVID-19 is significantly changing consumers' demand and habits. In order to understand consumer characteristics and find effective advertising directions in the post-COVID-19 era, this study set young consumers who are more sensitive to market changes and technological transformation from a subjective perspective of advertising audiences. Through the Q methodology, the advertising development model in the post-COVID-19 era was derived exploratively by examining their cognitive status of advertisements in the post-COVID-19 era. The model consists of three types of advertisements: "demand mining online ads" that value consumer demand and adapt to online shopping paths, "added value creation experiential ads" that value derived value and consumer experiences, and "practical and sentimental value creative ads" based on pragmatism and emotional values. In addition, this study also suggested for the sustainable practice of advertising in the post-COVID-19 era in various aspects, such as "seeking multidimensional values," "expanding consumer experience," and "mining and leading demand.

  • Hanger cables in suspension bridges are constrained by the horizontal clamp. So, the accuracy of estimated tension of hange cable using existing methods based on the simple mathematical model of singel cable decreases as the length of cable decreases because of the flexural rigidity. Therefore, back analysis and system identification techniques based on the finite element model are proposed recently. In this paper, the applicability of the back analysis and system identification techniques are compared using the hanger cable of Gang-An Bridge. The experimental results show that the back analysis and system identification techniques are more reliable than the existing string theory and linear regression method in the view point of the error of natural frequencies. However, the estimation error of tension can be varied according to the accuracy of finite element model in the model based methods. Especially, the boundary condition is more affective when the length of cable is short, so it is important to identify the boundary condition through experiment if it is possible. The tension estimation method using system identification technique is more attractive because it can easily consider the boundary condition and it is not sensitive to the number of input measured natural frequencies.

  • The present study argues that film director Lee Ae-rim animation works depict the world of the grotesque and not only are important sociocultural phenomena but also hold the significance of humor and subversion. The grotesque exhibits the intriguing characteristics of expressing a perspective critical of the existing society through the sensibilities of minorities and is used broadly as a term not only in the aesthetic sense but also designating sociocultural phenomena. Although discussed separately in terms of Mikhail Bakhtin's carnival grotesque and Mary Russo's uncanny grotesque, the grotesque fundamentally rejects existing order and conventions and is externalized through unique expressions, thus opening up a rich possibility for rejection, humor, satire, transformation, and deconstruction of and regarding the authority of the mainstream. Although they constitute a fictional medium, animation films are social products as well so that they are affected by society, culture, and history and stand as important texts that must be interpreted in terms of the relationships between humans' instinctive desires and society and between the overall culture and artistic media. However, the rarity of grotesque portrayals in South Korean animation films also proves that it is a society where even problems that are in themselves sensitive must be manifested ingeniously on a conventional level. South Korean society has a unique history of colonialism and national division and is simultaneously in the unique situation of a society that has undergone growth at a nearly unprecedented rate. Consequently, the society exhibits closed yet dynamic particularity where everyday tension and rigidity, wariness of others and extreme competition are intertwined in a complex manner. Intensively analyzed in the present discussions, director Lee's animation films and are characterized mainly by grotesque images, nonlinear narratives, and vivid depictions. In such a context, these works not only are artistic products of South Korean society but also rejections of a rigid society and share the significance of the aesthetics of the carnival grotesque, which consists of subversive expressions directed at a new world.

The Effect of Curiosity and Need for Uniqueness on Emotional Responses to Art Collaborated Products including Moderating Effect of Gender (독특성 추구성향과 호기심이 아트 콜라보레이션 제품에 대한 소비자의 감정에 미치는 영향: 성별에 따른 조절효과)

  • Companies recently introduce art collaborated products incorporating culture into a product. Art collaborated products include incorporating famous movies and/or design of an artist into a newly launched product. The introduction of art collaborated products are gradually increasing. However, research for this trend is relatively scarce. Although research concerning design has discussed a number of different factors as playing a role in influencing responses to design including culture, fashion, innate preferences, etc.), only limited attention has been paid to the processes by which consumers generate responses to product designs. People with different characteristics may respond differently. When people encounter these art products, they may become curious, may think that these products are unique, novel and innovative. People tend to show different levels of curiosity when they encounter new and novel objects, which they have rarely seen or experienced. Curiosity is defined as a desire for acquiring new knowledge and new sensory experience. Previous studies demonstrated that curiosity motivates individuals to engage in exploratory behaviors. People also show different levels of need for uniqueness, which is defined as being different from others or becoming distinctive among a larger group. Individual's need for uniqueness results from signals conveyed by the material objects that individuals choose to display. Recently, researcher have developed the need for uniqueness with three distinct constructs. These three concepts include creative choice, unpopular choice, and avoidance of similarity. Creative choice is a trait tendency of an individual by expressing or differentiating himself from others through consumptions of unique products. Unpopular choice is related to an individual's tendency to consume products, which deviates from group norms. Avoidance of similarity is linked to the avoidance of consumption behavior of products that are not famous. Past research implies that people with different levels of need for uniqueness show different motivational processes. Previous research also demonstrates that different customer emotions may be derived when consumers are exposed to these art collaborated products. Research tradition has been investigated three different emotional responses such as pleasure, arousal, and dominance. Pleasure is defined as the degree to which a person feels good, joyful, happy, or satisfied in a situation. Arousal is defined as the extent to which a person feels stimulated, active, or excited. Dominance is defined as the extent that a person feels powerful vis-a-vis the environment that surrounds him/her. Previous research show that complex, speedy, and surprising stimuli may excite consumers and thus make them more pleased and engaged in their approach behavior. However, the current study identified these emotional responses as positive emotion, negative emotion, and arousal. These derived emotions may lead consumers to approach and/or avoidance behaviors. In addition, males and females tend to respond differently when they are exposed to art collaboration products. Building on this research tradition, the current study aims to investigate the inter-relationships between individual traits such as curiosity and need for uniqueness and individual's emotional responses including positive and negative emotion and arousal when people encounter various art collaborated products. Emotional responses are proposed to influence purchase intention. Additionally, previous studies show that male and females respond differently to similar stimuli. Accordingly, gender difference are proposed to moderate the links between individual traits and emotional responses. These research aims of the current study may contribute to extending our knowledge in terms of (1) which individual characteristics are related to different emotions, and (2) how these different emotional responses inter-connected to future purchase intention of arts collaborated products. In addition, (3) the different responses to these arts collaborated products by males and females will guide managers how to concoct different strategies to these segments. The questionnaire for the present study was adopted from the previous literature and validated with a pilot test. The survey was conducted in Daegu, a third largest city in South Korea, for three weeks during June and July 2011. Most respondents were in their twenties and thirties. 350 questionnaires were distributed and among them 300 were proved to be valid (valid response rate of 85.7%). Survey questionnaires from valid 300 respondents are used to test hypotheses proposed. The structural equation model (SEM) was used to validate the research model. The measurement and structural model was tested using LISREL 8.7. The measurement model test demonstrated that consistency, convergent validity, and discriminat validity of the measurement items were acceptable. The results from the structural model demonstrate that curiosity has a positive impact on positive emotion, but not on negative emotion and arousal. Need for uniqueness has three different sub-concepts such as creative choice, unpopular choice, and avoidance of similarity. The results show that creative choice has a positive effect on arousal and positive emotion, but has a negative impact on negative emotion. Unpopular choice has a positive effect on arousal, but on neither positive nor negative emotions. Avoidance of similarity has no impact on neither emotions nor arousal. The results also demonstrated that gender has a moderating influence. Males show more negative emotion to creative and unpopular choices. Implications and future research directions are discussed in conclusion.
