While there are reports on the reliability of the universal goniometer (UG) and smartphone application goniometer (SG), there have been no reports on user impressions when using these devices. In this study, impressions of users of UG and SG that are used in clinical practice were clarified and reliability was compared. Questionnaires on user impressions were administered to 13 staff members who work in the clinical field. Measurements in the hip and knee joints of seven participants were taken by three testers, and intraclass correlation coefficients (ICC) were obtained to assess reliability. Results showed that SG was superior in terms of appearance, weight, texture, portability, usability, versatility and readout. SG was inferior in terms of setting up measurement axes. However, SG demonstrated high reliability even when compared to UG. The intra-and inter-rater ICC were 0.51 to 0.89 and 0.65 to 0.75, respectively.

We aimed to reveal typical-color effects to visual search for pictogram. We assumed that the typical colors shorten the response time of the visual search compared to the non-typical colors in the high color-associativity pictograms. In order to verify this hypothesis, we investigated typical colors and color- associativity of each pictogram in the first experiment and measured the response time of the visual search tasks. We analyzed the data through the color- associativity and the complexity of components perspective. As a result, we obtained the two conclusions as follow; 1) typical colors do not always affect response times, 2) response time is shortened in the typical colors pictograms that have the high color-associativity and consist of only one component. These results contribute to proposing the color design which permits efficiency in searching for pictograms in the facilities.

The purpose of this paper is to consider the Kansei (sensibility) of the architect Le Corbusier (1887-1965), concerning the process of change of the architectural concept on ‘Window’ from the viewpoint of Kansei-philosophy. Through the analysis of the architectural works, the author pointed out to Le Corbusier's 9 types of windows, ‘fenêtre en longueur (strip window)’, ‘pan de verre (glass wall)’, ‘pan de verre irrégulière (irregular glass wall)’, ‘pan de verre ondulatoire (wave glass wall)’, ‘aérateur (ventilator)’, ‘fenêtre (conventional window)’, ‘briques de verre (glass block)’, ‘claustras’ and ‘canon (gun)’. Through the analysis of the design process, the author concluded that Le Corbusier purified the physiological and multiple functions of the window by adapting each type of window.

“Resolution” in music theory means the chord progression by the transition from dissonance to consonance for providing more profound satisfaction to listeners than consonant chord only. The authors have investigated similar effects in temporal color transitions as an analogy of musical perception’s effect. In Part (1), the authors used various display patterns of three-colors combinations, measured the score of the color consonance with a sensory test, and revealed conditions where the “resolution” effect is enhanced. In Part (2), the authors focus on the conditions of gaze control. The fixation point appears as a small white dot on the black screen, and the observers are advised to fix their gaze onto the point. The white dot continues to appear while the observers watch the color arrangements and the transition. The experimental results suggest that the “resolution” effect appears more clearly when the color arrangements are captured in peripheral visual fields.

Our goal is to promote brain health through “bSports” (brain-Sports), a form of social sport competition using brain-machine interfaces. As the core technology, we have been developing an electroencephalography-based cognitive training system, “Neurotrainer,” using event-related potential as a virtual “mind switch” to control games. Here, we aimed to assess the performance of the Neurotrainer under competitive conditions between players. Fifteen pairs of healthy adults, including older people with tendency of degrading motor functions, were involved in a one-hour session of 4 games. Each player activated the mind switch to select one of eight pictograms to control his/her robot avatar for its desired action. All players regardless of age performed well at the level of about 85% success rate and reported that they had fun with our body-free technologies. These results suggest that bSports is an effective cognitive training and social activity that can be appreciated by people across all generations.

In this paper, the classification model of subjective affective value, its measurement, and the quantitative-analysis method were proposed first. Next, based on the proposal method, the value measurement experiment including the intuitive and unconscious decision-making phenomenon of the real world was conducted, and also separation and extraction of the affective value, and presumption of the value structure which became a decision-making standard by the analysis and evaluation of the degree of incidence especially were tried. As mentioned above, the validity of the proposal method was examined. As a result, it came to prove the validity of the proposal method.

Nagoya Cochin is one of Japan’s famous chicken breeds and was also the first domestic commercial chicken. The eggshell is a pink cherry-blossom color, with white speckles on its surface. The purpose of this study is to develop an eggshell color index for quality control to improve the commercial value. This study consists of two experiments. In the first experiment, the eggshell color of sixty eggs was measured by a colorimeter TC-8600A, and a visual evaluation using photo images of each egg was conducted by fourteen visual inspection experts. They scored on a Likert scale of five steps on four criteria: attractiveness of color, attractiveness of white speckles distribution, overall attractiveness, and preference. The relationship between the eggshell color and the visual impression was analyzed on a Hunter Lab color space. In the second experiment, a range of color variations of eggshells were generated on a screen using Adobe Photoshop, and a visual evaluation of three hundred and fifteen egg images was conducted by seven experts. It is hoped the results from both experiments will be useful for agricultural producers to develop more attractive products and increase the commercial value of Nagoya Cochin chickens.

The idea of ecosystem services has been highlighted in order to identify a variety of benefits that human beings obtain from other life forms and to raise people's interest in conserving biodiversity. This idea helps us recognize the connection between our lives and environments and more actively participate in ecological activities. While this sort of instrumental approach to the conservation of biodiversity is particularly important for the growth of public participation, it also limits our understanding of its purposes. This paper, on the basis of field research conducted in Sado, Niigata, illustrates complex value issues involved in conserving biodiversity and discusses the importance of our kansei to uncover various values of the surroundings. As an approach for enhancing such kansei, the authors argue that multi-generational dialogue contributes to sharing different views of the participants and thereby cultivating a comprehensive perspective in environmental decision-processes.

This paper discusses the changes of magazines which women read according to the age using figures of the network, which we got from the answers to questionnaire of women's junior college students. The link of the network expresses frequent combinations of magazines read in the same period or frequent changes of magazines which women read. This paper covers fashion magazines, comic magazines and animation magazines. At first, it is found that the combination of magazines with a similar property are read in the same period. Next, changes of magazines which women read is clarified. 51.22%, 28.66%, and 19.51% of the college students read “Chao,” “Ribon,” and “Nakayoshi” in their childhood, respectively. Readers of “Chao” and those of “Ribbon” come to read fashion magazines or boys' comics for teenagers, and then street fashion or girly fashion magazines. “Nakayoshi” readers, however, tend to continue reading comic magazines sequentially.

We investigated the RGB and XYZ components of the natural colors (two cherry blossoms, i.e., Someiyoshino and Youkou, and the emission of Heike-firefly), and the physiological effects on Japanese and foreign people were compared. The natural colors were digitally measured as RGB colors, and then they were used as color stimuli. The psychological effects were investigated by administering a questionnaire, which was based on the Semantic differential (SD) method. From the results of the questionnaire, the degrees of expression for the natural colors were quite different between Japanese and foreigners. The kansei on the natural colors between Japanese and foreigners were also different in terms of psychophysical quantity and physical cognition. The results of factor analysis showed that the color of Youkou gave pleasantness to Japanese people, whereas the colors of Someiyoshino and firefly gave pleasantness to foreign people.

This study is designed to obtain primary knowledge relevant to impressions on figures, and clarify the effects of color, shape, and location on the impressions on figures by psychology experimentation. A measurement is conducted using the combinations of 3 types of shape, 4 types of color, and 5 types of location. The experimental results show that the most dominant factor that affects the visual impression is the location of a figure, and suggest that the central location is considered well-balanced and favorable. Then, the color is the second most influential factor in the visual impression, and “yellow” yields impressions of gaiety and cuteness, however, “blue” to the contrary yields impressions of gloom and no cuteness. Additionally, the results suggest that the shape is the least influential factor in the visual impression and almost neither types of shape used in this experiment are nice-looking nor cute and have any specific features.

The present paper proposes a real-time rendering method based on object surface properties and multi-spectral reflection model. An RGB image is device-dependent and valid for only the fixed conditions of illumination and viewing. On the other hand, spectral reflectance information of an object surface is more useful than RGB information because we can create realistic images of the object under arbitrary illumination and viewing conditions. Firstly, we develop a 3D reflection model based on Nayer model, Torrance-Sparrow model, Fresnel model and multi-spectral information for precise description of object surface reflectance. Secondly, we develop a rendering algorithm of the object under ambient light source distribution. And also, we implement the reflection model to Graphics Processing Unit(GPU) for improving rendering performance. Finally, we render some objects by using multi-spectral reflection model. The overall feasibility of our method is confirmed based on computer graphics images created by using the estimated parameters.

This study verified how timing of sound effects affects the user's operation performance with interactive content, such as computer games. We conducted an experiment to test the hypotheses that (1) operation performance is slightly degraded if the sound effects lag behind the visual beat with “good” timing and (2) operation performance is substantially degraded if the sound effects lag behind the visual beat with “bad” timing, where the “visual beat” in interactive content is the repetition of periodic visual accents in visual images. Our findings indicate that a delayed timing of sound effects degrades the operation performance, but the degradation depends not only on the degree of delay of the sound effects, but also on how in tune the sound effects are with the visual beat.

In this paper, we carried out a subjective evaluation on the perceptual difference in female speech to show the gender difference in its likability and analyzed a relationship between the acoustic features and subjective scores. This subjective evaluation used female speech uttered by 21 speakers as the stimuli, and 127 subjects (47 males and 80 females) attended it. The results suggested that there was the speech preferred without the gender difference and preferred by one gender. We then analyzed the correlation between subjective scores and five acoustic features: fundamental frequency, formant frequency, amplitude difference, spectral centroid and spectral tilt. In female subjects, statistically significant correlations were observed in all features. In male subjects, significant correlation was observed only in spectral tilt. In particular, correlation in spectral tilt showed the inverse trend between male and female subjects. These results suggest that the spectral tilt is effective in the gender difference.

Healing music and Musicotherapy attract attentions recently. They are beginning to be used in the medical treatment. On the other hand there are little practical utilization to relax with video images compared with music. Visual information is said to occupy about the whole of 80% humans receive from five senses. Therefore it has some potential that visual information affects human's mental and physical state as well as aural information does. This paper attempts to investigate the relation between characteristics of video images and mental relaxation. The one of characteristics we focus is motion speed of video images. It is considered that it might correspond to tempo of music. This paper investigates the relaxation effect by using the index calculated by heart rate variability analysis. The experimental results and analysis confirmed that viewing video images might have higher effect of reducing stress than eyes closed state and the relaxation effect might depend on motion speed.

Color has long been considered important by both the manufacturing industry and academia because it affects people’s perceptions, emotions, and behaviors. However, the evaluation of purchasing behavior until now has mainly been only in an experimental environment, and there have been concerns that differed from the actual consumer behavior. Therefore, the causal effect of the strong impression of a manufacturer’s brand color on the purchase behavior in the Japanese automobile industry was verified. Covariate was homogenized by propensity score matching based on the online survey, and the causal effect on purchase intention was extracted. As a result, the impression of the brand color had a positive effect on the purchase intention. This effect was estimated to be 5.739 in odds ratio. Commercial brands, logos, emblems, car body colors, dealers, showrooms, and even professional baseball teams were found to be factors that foster brand color.

The purpose of this study is to examine tightening pressure of the supporter and effect of the elastic property on muscle fatigue through electromyogram measurement. Wearing a magic tape style taping supporter, several healthy students carried out the flexion experiment of the elbow. At this time, the electromyogram of biceps brachii was measured, and MFCV(Muscle Fiber Conduction Velocity) by which, the muscle fatigue index was calculated. As a result, it became clear that the tightening pressure of the supporter which relieves fatigue was 21-28gf/cm2. The elastic property of the supporter which relieved muscle fatigue was almost 0.8kgf/cm as a tension stretch. Local clothes pressure seems to affect that the supporter with the moderate elastic property is fixed in the appropriate tightening pressure in muscle contraction and muscle blood flow. This was assumed to be the reason why muscle fatigue is reduced.

When infants are in their crawling stage, both mothers and infants experience difficulties while changing diapers. We evaluated the effects of pull-up type diaper on physical and psychological burden in comparison to the nappy-type diaper. Twenty-four mother-infant dyads participated in this study. According to the behavioral observation analysis, negative behaviors of mothers and infants while changing pull-up type diapers were significantly lesser than while changing the nappy-type. Pull-up type diapers took mothers 30% lesser time to change, while allowing infants more physical movements than the nappy-type. A spectral analysis of infants' heart rate variability showed that low-high frequency ratio and the change in normalized unit percentage (Nu%) were significantly lower when pull-up type diapers were changed. Negative emotion-related behaviors of both mothers and infants significantly correlated with change in Nu% of infants. Lower physical and psychological burden while changing diapers was associated with pull-up type diapers.

In fashion Business, turnover of stores is decided by the product appeals of fashion apparels and selling capacity of the fashion apparel store. In order to increase the turnover, the selection of apparel goods which are preferred by consumers of the shop is most important. Next, the selling capacity is important. In previous papers, we discussed about the relation between apparel goods and consumers. Fashion apparel is thought to be a carrier of the information which is proposed by the fashion designer. On this account, we assumed the purchase and sale of fashion apparels are the diffusion phenomena of the information in the behavioral space. From the point of view, we propose a mathematical model describing the purchase and sale of the fashion apparels.

In this study, we investigated the relation between autism spectrum tendencies of normal observers and evaluation of facial emotional expressions, used for “Ban Dainagon Emaki”. Recognition of facial expressions was verified by Scheffé’s (Nakaya) paired comparison method using the evaluation attributes of the four emotions (fear, anger, sadness, and happiness) in conjunction with investigation of the Autism-Spectrum Quotient (AQ). Different cognitive patterns especially extracted from communication ability, were confirmed, comparing facial expression recognition tendencies for the two groups, higher levels of autistic - like traits and lower levels of autistic - like traits. Between the two groups, the high levels on the AQ were difficult to recognize the fear of negative emotions, but regarding the happiness of positive emotion, similar tendency was demonstrated. These results are consistent with the findings obtained from previous studies on the tendency of facial expression recognition between healthy individuals and those with traits of ASD.
