The photomontage of lotus seedpods on human skin has been called “Hasu-colla” in Japan, and this can elicit strong aversion in viewers. Previous studies have reported that lotus seedpods evoke core disgust, and that Hasu-colla relates to animal reminder disgust. However, the relationship between unpleasantness evoked by lotus seedpods and that by Hasu-colla has not been demonstrated. The present study investigated whether Hasu-colla evokes stronger disgust than lotus seedpods presented alone as well as differences between background objects (from animal to stone) in evoking aversion. Hasu-colla induced stronger unpleasantness than did lotus seedpods and background objects presented alone (Exp. 1 and 2). The amplification of unpleasantness was weakest in stones and strongest in dogs among animals (Exp. 2). Lotus seedpods, which are related to disgust for clusters, evoke strong feelings of contamination, supporting the possibility that such clusters are associated with scars and sores.

Outerwear colors of H&M, ZARA, and UNIQLO were objectively investigated through their official online stores for a whole year, to clarify the common and particular features in colors among fast fashion brands. This study has focused on hue distribution, annual change, the basic and accent colors. Color feature of male and female outerwear in three brands are summarized respectively, and results demonstrate that colors of male and female outerwear in each brand are mainly low-chroma and achromatic colors, meanwhile colors with high-chroma are concentrated in the area between red and yellow direction; outerwear colors of fast fashion brands are affected by seasons, generally colors seem vivid and bright in spring-summer season, dull and dark in autumn-winter season; basic colors "white, black, navy blue, brown, gray" used in traditional apparel industry are utilized in fast fashion brands as well.

Unintended accelerations (UA) occur in vehicles unexpectedly and uncontrollably. Every year, numerous critical injury and death cases related to UA occur. Recently, researches related to the development of automated driving systems are attracting a lot of attention among researchers and vehicle manufacturers. Additionally, silent vehicles such as electric power and hybrid vehicle are increasing. However, there are negative effects on driver safety. Recognition time (RT) and recognition velocity (RV) are some of the important factors lead to avoiding crashes. Early detections give the drivers more time in decision-making toward the UA hazards. In this study, RT and RV toward UAs under various environments were analysed. The findings highlighted that RTs toward UAs were longer in no engine sound environment. Drivers were unable to respond to UA earlier in silent vehicles compared to conventional vehicles. The findings provide insights that can be useful in developing automation vehicle and silent vehicle.

This paper describes an electroencephalogram (EEG) response while imaging music with and without listening to it. It is reported that, by performing actions (such as singing, imaging, etc.) in synchronization with music, we can feel more pleasant than when not performing these actions. We think that emotions (such as pleasantness, sadness, etc.) may be different between imaging music with and without listening to it. Taking these issues into consideration, we investigate activated parts of the brain while listening or not listening to known and unknown music to explore the source of emotions evoked by past experiences. As a result, the visual cortex is activated while listening to known music, but it is not activated while listening to unknown music. In conclusion, we know that the subjects tend to perceive known music more visually when imaging music with listening than when doing without listening to it. This may suggest that the activation of visual cortex is related to the emotions evoked by past experiences.

In this paper, first, analyses of local community mascot characters are carried out to obtain knowledge to be the popular ones. Next a mascot characters automatic creation system is proposed using these findings. As for the analyses, we used 200 mascot characters. Many interesting findings could be obtained such that dark-round eyes tend to contribute to be popular as a mascot character. The proposed system utilizing these findings can create a mascot character reflecting a user's image inputted by affective words. Many parts having degrees of affective images are prepared in the proposed system and are combined to form a character using Rough Sets Theory and an Interactive Genetic Algorithm framework. We performed evaluation experiments. Many mascot characters satisfying user's image were created and remarkable results were obtained through subjective evaluations. For example, by using the extracted rules from the analyses and Interactive Genetic Algorithm, the proposed system can create much favorable mascot characters. Moreover, we found some interesting tendencies of the color used to paint characters. One of them is that gentle characters are often painted in colors with low saturation.

We investigated the memory task performance and the central nervous activity after smelling two kinds of pan-fired Japanese green tea to examine their physical and psychological effects. Twenty eight subjects participated in this study. We used Koushun and Kouju for test samples, which were made by different manufacturing processes. After smelling each odor sample, a memory task and an arithmetic task were used to test mental stress. Electroencephalogram (EEG) was recorded before and after smelling the test samples, and EEG activity was estimated for 4 frequency bands (alpha 1, alpha 2, beta 1 and beta 2). The profiles of mood states (POMS) and the visual analog scale (VAS) after mental stress task were completed for subjective assessments. The results showed that the odor of Kouju may induce a positive emotion. It may also affect the EEG band power of beta 1 at right frontal region and improve memory task performance.

This study aims to suggest improvements in the functionality and comfort of hygiene masks. Our preliminary study surveyed users' actual experiences of wearing masks from individual sensory, cognitive, and holistic perspectives. We surveyed 1519 Japanese university students, obtaining information on whether they wore masks, the purpose of the mask, and if there were any problems with wearing masks. We studied reported problems versus intended use by calculating the co-occurrence relationship. The aggregated results showed that women wore masks more frequently than men, and the most common reasons for wearing them were to guard against influenza and the common cold. Reported problems, such as discomfort due to “Humidity”, were cited by both men and women. Using a text mining approach, we identified that this awareness of problems brought on a “feeling of distraction”. Our findings will aid in the design and development of less unpleasant and more practical masks.
