In this study, the Model of Emotion Evaluation, an emotional analysis actively applied in environmental assessment, was divided into two parts, the abbreviated model and the inferential model, through pilot study and experiment. In addition, an analysis was conducted through the experiment on the attributes of the evaluation vocabularies of two additional types of representative models, the EPA Model and PAD Model, and the results show a huge difference in the development approach and lexical constitution of the two models. It was also identified through factor analysis that the vocabularies were abbreviated according to the respective models. Similarity relationships were analyzed using multidimensional scaling and the results show that mutual relationship was established to some degree. Based on this, we can conclude that, rather than a biased use of the Model of Emotion Evaluation in emotion evaluation, a more objective image analysis is possible by analyzing the characteristics of the model before applying it. In this study, the evaluation target was confined only to the environmental assessment of streetscape and continuous research on the Model of Emotion Evaluation that allows for the comparison of evaluation models in various areas is needed.

There are few that evaluate tactile emotion as it pertains to car interior parts, while studies on visual evaluations of car interiors as well as usability tests in a visual sense are numerous. The purpose of this study is to determine typical in-vehicle tactile emotions so that they can be used to evaluate tactile impressions of car interior parts. 52 words related to tactile impressions of car interiors were gathered from a survey in conjunction with an in-vehicle test, interviews with the car salespersons, and an analysis of car reviews. After a factor analysis with 52 words, 10 categories of major tactile emotions were clustered. These were roughness, toughness, friction, comfortability, stiffness, softness, temperature, sleekness, familiarity, and flexibility. These representative tactile emotions regarding a car interior can be used to evaluate tactile impressions of surfaces such as leather, plastic, metal and wood when used as parts in car interiors.

User-created text data are increasing rapidly caused by development of social media. In opinion mining, User`s opinions are extracted by analyzing user`s text. A primary goal of sentiment analysis as a branch of opinion mining is to extract user`s opinions from a text that is required to build a list of emotion terms. In this paper, we built a list of emotion terms to analyse a sentiment of social media using Facebook as a representative social media. We collected data from Facebook and selected a emotion terms, and measured the dimensions of valence and activation through a survey. As a result, we built a list of 267 emotion terms including the dimension of valence and activation.

This study aimed to investigate the differential effects of self-relevance on framing effects. For this purpose, the participants were allocated into two frame type conditions(positive vs. negative), and asked to respond on six decision-making scenarios manipulated by self-relevance levels(low vs. high). The results can be summarized as followings. First, although self-relevance level made no significant difference in framing effects, the positive frame condition tended to induce larger framing effects than the negative frame condition. Second, no significant interaction effect between frame type and self-relevance level condition was found in the positive condition, whereas high self-relevance level condition induced smaller framing effects than law self-relevance level condition in the negative frame condition. These results indicated that although self-relevance tended to reduce framing effects, this effect can be differed in frame types.

The final aim of the present study is to build a system of converting a color image into musical elements based on a synesthetic perception, emulating human synesthetic skills, which make it possible to associate a color image with a specific sound. This can be done on the basis of the similarities between physical frequency information of both light and sound. As a first step, an input true color image is converted into hue, saturation, and intensity domains based on a color model conversion theory. In the next step, musical elements including note, octave, loudness, and duration are extracted from each domain of the HSI color model. A fundamental frequency (F0) is then extracted from both hue and intensity histograms. The loudness and duration are extracted from both intensity and saturation histograms, respectively. In experiments, the proposed system on the conversion of a color image into musical elements was implemented using standard C and Microsoft Visual C++(ver. 6.0). Through the proposed system, the extracted musical elements were synthesized to finally generate a sound source in a WAV file format. The simulation results revealed that the musical elements, which were extracted from an input RGB color image, reflected in its output sound signals.

The main causes of traffic accidents while driving a car is of the driver`s visual distraction. In this study, the color sensitivity of the information projected on the windshield were evaluated for HUD (Head Up Display) system which helps the driver`s eyes on the road while driving. The driving Information were projected 9˚ downward from front sight 0˚ under lab`s fluorescent lights, LED floorlights and the TV had having 25 [lux] illumination when driving at night environment and 100,000 [lux] of daylight environment. Munsell color hue of the basic five colors (R, Y, G, B, P) and the color of traffic lights YR, W were the color of the seven characters, each character were outlined by White, Gray except for W. Total of 19 experimental stimuli was shown in the environment of day and night driving for asking visibility information of color, fatigue, preferences, and evaluate the degree of interference. The results came out that the bright Y and G color is visibility significantly for daylight. Second, with the outline of the text, the color of the outline works as a background for luminance contrast effects and affects visibility. Third, without the outline, the glass in front of the vehicle acts as the background and the luminance contrast of characters achieve greater brightness and visibility. The luminance contrast between the stimuli and background should be considered for increasing color visibility for driving information which is an important factor for HUD commercialization.

For video reality improvement, there has been much advancement in the methods of providing visual, auditory, and tactile information. On the other hand, there is little research on olfaction for video reality because it is difficult to define and knotty to manipulate. As a first step for video reality improvement using olfactory information, this research investigated users` acceptability of smell when they watch videos of various kinds and then classified the video clips based on their acceptability of different criteria. To do so, we first selected three questions of whether the scene in the video appears to have an odor (odor presence), whether a matching odor is likely to improve a sense of reality (effect on sense of reality), and whether s/he would like a matching odor to be present (preference for the matching odor). Then after collecting 51 video clips of various genres that would receive either high or low ratings for the questions above, we had participants to watch the videos and rate them for the above three questions on 7-point scale. For video classification, we paired each two questions to construct 2D space to draw scatterplot of video clips where the scales of the two questions represent X or Y axis. Clusters of video clips that locate at different quadrants of the 2D space would provide important insights in providing olfactory information for video reality improvement.

Positive affect has beneficial consequences in various life domains including social relational aspect. This study proposes that ``joy``, a highly arousing positive social emotion, promotes emotionally supportive reactions during a social interaction. In Study 1, after controlling for confounding personality characteristics (e.g., extraversion, agreeableness, adult attachment) and cognitive variables (e.g., empathy, self-esteem), positive affect predicted the amount of emotional support and enthusiasm one showed to a person who was describing a positive experience. The arousal dimension of positive emotion appeared to be the key in creating this outcome. Study 2 found that people were most likely to react in supportive ways (e.g., more laughing, emotion sharing, and active-constructive responses) to other`s conversation after viewing a joy-inducing (rather than pride, awe, calm) film clip. These results partly explain why happy people are socially popular and suggest that one of the central functions of “joy” is to promote social bonding with others.

In this study, the effects of driver`s neuroticism on situation awareness(SA), eye movement(EM), and driving performance were examined. In Experiment 1, in which static driving scenes were presented, it was found that the drivers of higher neuroticism showed shorter percentage of dwell time and less percentage of fixation counts for the peripheral area than those of lower neuroticism, although SA scores yielded no difference between the two neuroticism groups. In Experiment 2, differences in the drivers` driving performances as well as SA and EM as a function of neuroticism were compared using driving simulation. The results of Experiment 2 showed the followings. First, contrasting to Experiment 1, the high neuroticism group showed lower SA score than low neuroticism group. Second, the pattern of EM was similar to those of Experiment 1. Third, high neuroticism group deviated more from center of road, and drove slower than low neuroticism group.

Using social network analysis, this study examined cognitive representations of ideal public figures as well as politicians and entertainers who are often regarded as public figures in Korea. Participants expected ideal public figures to possess only positive characteristics, such as high morality, integrity, competence. However, their assessment of politicians and entertainers reflected in their cognitive representations turned out to be fairly different from the image of ideal public figures. Personality traits and behavioral characteristics featured in cognitive representations of politicians were dominantly negative. Cognitive representations of entertainers incorporated both positive and negative characteristics highly interconnected to each other. This study also explored how people respond affectively toward ideal public figures, politicians and entertainers. Participants showed only positive feelings toward ideal public figures. However, their` affective responses toward politicians were entirely negative and toward entertainers, both positive and negative affects were shown. We discussed the disjunction between the representations of politicians and entertainers and of ideal public figures and suggested directions of future research.
