In the process of product design, shaping is the process of making a substantive existence, and ultimately it generates the outcome. The process of shaping is generally led by designer's initiative work, and in this process, various formative elements are used to generate the outcome. In this research, the basic purposes are to figure out the differences of elements which generated by the differences of consumer's and designer's view in the process of shaping of the product, and the characteristics of the affective responses caused by those differences. Also, it will examine how the consumers can directly participate in the process of the shaping of the consumer-participated product, and the feasible guidelines of design in which consumers' needs can be reflected more efficiently to the process of shaping. As a result, consumers and designers have certain degree of difference of view-point about the formative element of the shape. The difference was due to subjective common ideas of design in case of designers, and in case of consumers, it was due to their immature visual understanding. There is another experiment of affective response about the shape of the product. First, I established the sensible image vocabulary based on the shape of the product. And based on the vocabulary, I carried out the same experiments to the consumers and designers.

A comfort evaluation of car seat clothing has been proposed for high comforts interior seat clothing. Car seat covers have received wide spread attention due to their man-machine interface working. And then, it will be necessary for measurements on delicate basic mechanical-properties, which closely relate with human touch feeling of its materials. In this research, we have utilized $KES-FB^{(R)}$(Kawabata Evaluation System) series, $^ST300{(R)}$ analogue softness tester and friction tester for measurement a physical properties. In order to consider both kansei and physical properties on interior seat covers, we firstly have established subjective words of judgement for the seat covers. Secondly, related them to the objective measurement of physical properties. Each kansei-language has clearly defined as 'Softness', 'Elasticity', 'Volume' and 'Stickiness' for the adjectives of leather car seat covers. These technical terms have correlated to physical properties in other words, h (mm), bending moment ($gf^*$cm/cm), To-Tm (mm) and ${\mu}$. At this time, fuzzy logic has utilized to predict the value of kansei language through physical values. On the basis of this result, finally it is possible to predict quality index of car seat covers using neural networks technique. In short, we develop a quality evaluation system of car seat clothing combining four physical quantities with kansei engineering.

Recent development of 3D technologies made it possible that observers perceive 3D depth from two dimensional images. Despite this kind of technological development, when observers watch 3D display they experience 3D visual fatigue that they do not usually experience in real life. It is critical to measure visual fatigue in order to overcome the problem of 3D visual fatigue. The purpose of the present study was to develop a protocol to measure 3D visual fatigue based on an EEG signal and to examine its validity. The first experiment explored the possible ERP components that reflected visual fatigue in 2D and 3D conditions. The second experiment examined whether the feature of the component found in the first experiment was affected by the amount of binocular disparity. Both in Cz and Pz channels, the peak amplitude of P3 component was much lower in 3D rather than in 2D conditions, and it decreased as the amount of binocular disparity increased. The subjective 3D visual fatigue also increased with the amount of binocular disparity. These results imply that the peak amplitude of P3 component at Cz and Pz channels can be used as an index of 3D visual fatigue.

The purpose of this study is to test the effect of pedagogical agent realism and expertise on persona effect. There were two perspectives of the pedagogical agents' social interaction. Self-identification hypothesis argues that complexity of agent image is better to increase social interaction. Subjective identification insists that simplified image is more helpful to facilitate social interaction. However, from the cognitive load theory perspective, learners' expertise can be a major factor to determine persona effect. Sixty-eight college students (male=19 and female=49) participated. The independent variables were the degree of realism of pedagogical agent (detailed vs. simplified image) and the expertise (high prior knowledge group vs. low prior knowledge group). The dependant variables were comprehension test and the agent persona instrument (API). There was no significant difference in comprehension test score; however, there were significant interaction effect on the most constructs of API: 1) facilitating of learning, 2) credible, and 3) human-like. The follow-up analysis of simple main effect revealed that high expertise group showed significantly higher perception of the three construct with high realism of pedagogical agent. The results of study show that learners' expertise plays a key role of perception of persona effect.

The present study have investigated the effect of the characteristics of stereoscopic images and viewing environment on visual fatigue. We manipulated the speed of stereo images with motion-in-depth and viewing distance, which were used as representative variables of the characteristics of stereo image and viewing environment, respectively. Visual fatigue was evaluated with use of a subjective questionnaire which is consisting of 5 different and independent factors: "Eye pain", "Visual stress," "Nauseousness", "Body stiffness", and "Blurriness". In general, when viewing time increased from 10 minutes to 20 and 40 minutes, observers felt severe visual fatigue. Among other factors, only the factor score of "Nauseousness" was significantly increased as the speed of object moving in depth became faster. When viewing distance was increased, the score of "Blurriness" was decreased. These results suggest that different kind of the visual fatigue might be induced depending on characteristics of the stereo images and viewing environment.

Because the educational significance of reading activities for growing children is so great, the importance of reading cannot be overemphasized. While the reading volume of elementary school students in Korea is very high, as they go up to middle school, the reading volume falls rapidly. This study examined a more effective way to resolve this middle school reduction in reading volume. Middle school freshmen were surveyed on their reading habits and preferences in the sixth grade of elementary school, after which the groups were divided into two groups based on their averages; groups with high/low reading habits and groups with high/low reading preferences). Participants also wrote reading reports for six weeks, kept a record of the days of the week they read for more than 20 minutes, and noted down the time they read in minutes. It was found that 75% of participants did not read one book a week when in the sixth grade of elementary school and it was confirmed that reading many books and liking to read were elements that had different dimensions. For example, about 35% of the participants said they liked books but rarely read them. It was also confirmed that the reading habits formed in elementary school were a strong variable that affected the number of days that and the reading time of middle school students rather than the reading preferences formed in elementary school. This study concluded that a subjective attitude toward reading and actually reading were completely different problems, which suggested that 'habits' could have a greater influence than 'preferences' when performing tasks to achieve goals.

Previous studies using facial expressions have revealed valence and arousal as two core dimensions of affective space. However, it remains unknown if the two dimensional structure is consistent across ages. This study investigated affective dimensions using six facial expressions (angry, disgusted, fearful, happy, neutral, and sad) at three ages (young, middle-aged, and old). Several studies previously required participants to directly rate subjective similarity between facial expression pairs. In this study, we collected indirect measures by asking participants to decide if a pair of two stimuli conveyed the same emotions. Multidimensional scaling showed that "angry-disgusted" and "sad-disgusted" pairs are similar at all three ages. In addition, "angry-sad," "angry-neutral," "neutral-sad," and "disgusted-fearful" pairs were similar at old age. When two faces in a pair reflect the same emotion, "sad" was the most inaccurate in old age, suggesting that the ability to recognize "sad" decreases with old age. This study suggested that the general two-core dimension structure is robust across all age groups with the exception of specific emotions.

This study evaluated the effects of latex mattresses on sleep quality and comfort. The participants were 11 healthy adults (five males, six females, mean age 37.7 years, mean height 167.8 cm, and mean weight 67.0 kg) without severe insomnia or other disease that could affect sleep, examined by a clinician. In their personal living space, participants slept on a spring mattress for 7 days, with their sleep registered using a wearable device (Fitbit), a sleep log, the Pittsburgh Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), and a satisfaction survey. The mattresses were then replaced with latex mattresses, which were used for 14 days. As a result, sleep time increased by 62.9 min on weekdays and 53.2 min on weekends after using the latex mattress, and a significant decrease, of 3.8, as seen on the ISI. As measured by the PSQI, the poor sleepers decreased from 10 to 7, but this was not statistically significant, and in the satisfaction survey, the comfort of the low back, neck, and shoulders was significantly increased. This suggests that changes to latex mattresses may positively affect objective and subjective sleep quality.

This study determines whether the perception of the frequency of experiencing positive, negative, and surprise emotions changes according to the level of cognitive well-being. Furthermore, we determined practical means to analyze which emotions can be managed in daily life as an effective means of improving overall life satisfaction by identifying representative specific emotions that strongly predict the level of cognitive well-being. To this end, the between-subjects factorial design is adopted to measure the frequency of emotional experiences according to the level of cognitive well-being in 438 university undergraduate students. For cognitive well-being, the life satisfaction scale (SWLS) was used, and the PANAS-X scale was used to measure emotional frequency. As a result, first, the group with high cognitive well-being displays a higher frequency of positive and surprise emotional experiences and a lower frequency of negative emotional experiences than the group with low cognitive well-being. Second, the results confirm that representative emotions affecting cognitive well-being included 8 positive emotions, 7 negative emotions, and 1 surprise emotion. Among them, positive emotions include "happy" and "confident," negative emotions include "dissatisfied with self" and "disgusted with self," and surprise emotions include words such as "amazed." Therefore, we can conclude that the representative emotions are those with the greatest influence on cognitive well-being. Therefore, increasing the frequency of specific emotions (e.g., happy, confident, and surprise) and decreasing the frequency of others (e.g., dissatisfied with self and disgusted with self) could be effective in improving cognitive well-being than unconditionally examining emotions experienced in daily life.
