    Through this research, I intend to show how improving the fit of a mask can benefit sufferers of hay fever. Currently available masks absorbed a large amount of pollen during experiments. However, the effects of wearing these masks are unclear. Therefore, I am interested in the fit of masks on faces. For quantitatively evaluating the fit ability of a mask on a face, I developed a device that measures the strain behavior of sheets and faces at the time of wearing a mask. To investigate the fit ability, angle change and position change at the time of vowel pronunciation were measured using the developed device comprising two shape sensors and a digital video camera. There were five measurement points on both the mask and face: two points ‘nc’ and ‘ns’ on the nose, one point ‘cc’ on the cheek and two points ‘jc’ and ‘js’ on the jaw. The first letters ‘n’, ‘c’ and ‘j’ denote the nose, cheek and jaw, respectively. The second letters ‘c’ and ‘s’ denote the centre and side, respectively. Four types of masks made of different materials and of different shapes were adopted as experiment samples: a 2D gauze mask, 3D gauze mask, pleated non-woven mask and molded non-woven mask. The subjects were seven young women. The fit ability of a mask was studied from the viewpoints of angular differences and correlation coefficients between a mask and a face, and the distance between the mask and face was measured. Analysis of angle changes showed that at point ns, the gauze masks assumed a convex shape against the face. The correspondence between results obtained for the gauze masks was lower at points ns, jc and js, whereas that for the non-woven masks was higher at points nc and cc. Moreover, analysis of the position changes revealed that the maximum vertical distances of the gauze masks were larger at points jc and js. These results proved that different materials and shapes of a mask yield different fit abilities.

    We have found that the sense of brilliant observed from an image is deteriorated by a digital processing of granular noise reduction. By seven grade subjective assessment tests about “sense of brilliant” removing and adding isolated impulsive dots, “sense of brilliant” was deteriorated “-2”(reduction) and improved “+1”(addition). We have found the more than 5.4% isolated impulsive dots of total pixel greatly generated “sense of brilliant”.

    Impression made by the color of cellular phones was investigated. We presented pictures of an identical cellular phone with 16 different body colors to 194 observers and asked them to evaluate the appearance of the pictures by using the Semantic Differential (SD) method. The results of factor analysis indicated that there were three factors of impressions: masculine-feminine, gorgeous-staid, and evaluation. A subsequent confirmatory factor analysis supported the factorial validity of the proposed three-factor model. It also revealed that there were significant gender differences in certain factor scores and intrafactor correlations. We applied the “positioning analysis” method (Toyoda, 2001) for the SD data, and mapped the loading values for SD scales and colors on a 2 dimensional plane. Implications regarding the underlying structure of impression and its relationship with the body color of cellular phone are discussed.

    This paper aims to propose a procedure to decide a color of a bridge, in the view of aesthetics with considering the color harmony of the bridge and its surroundings. Generally, bridge aesthetics is considerably influenced by color selection of the bridge. Therefore, in deciding a color of a bridge, relations or harmony of colors of the bridge and its surroundings should be considered. However, as far as authors know, the procedure to decide the bridge color is not established yet. With this background, this paper proposes a procedure to select color of bridge with considering the color harmony to the bridge surroundings, here the procedure is proposed with modifying the Design Plan for Three-Color Harmony by Naya, et al. The proposed procedure is applied to some bridges, and effectiveness is confirmed.

    A questionnaire survey is made on impression of landscape scenes including a bridge. 7 photographs which include bridges are used for the survey. In addition, to secure the accuracy of the survey, 8 dummy photos with no bridges are also examined together with the photos of bridges. In the survey, first, overall impressiveness of each scene is examined, then up to three impressive objects in each photo are enumerated. The survey is made for 96 testees, and the impressiveness is evaluated into 4 grade of “very good”, “good”, “poor” and “very poor”. The results of the survey indicate that the almost testees mention the bridge as impressive objects in all photos, even if the bridge occupies very small area in the photo. When a bridge has the null background, the testees notice the dimension of the bridge rather than its color, although the shape or color is noticed with the complicated background. The results also indicate that the almost testees evaluate the bridge as “very good” or “good” impression, even if the overall impression of the photo is “poor”.

    Tactile impression of 20 types of cushions filled with beads was estimated by the sensory evaluation of SD scale. Factor analysis and quantification theory I among multiple classification analysis were applied to the results of the sensory evaluation. Three main factors were obtained and we named them the sense of security, the fit feeling, and simplicity. The sensory evaluation results for each sensory word were explained by the score of the item/category (type of covers and beads). The relationship between the sensory evaluation results and mechanical properties of expanded plastics beads were also examined. Smaller expanded bead was related to goodness of touch feelings.

    This paper is aimed at evaluating the effect of prolonged mental stress on human physiological state. The human secretory immune and endocrine substances were introduced as “biomarkers” of such a prolonged stress. This relatively new field of study investigating the relationship and/or interaction between human mental and somatic states has been developed according to the development of the molecular analysis techniques, such as Enzyme-linked immunosorbent assay (ELISA), and showed that the several secretory hormones and immune substances could possibly be useful stress markers. However, what types of stressors and its duration could be evaluated by such biomarkers is not well understood. In this article, the effect of prolonged mental stress during long-term graduation examination of undergraduate students was investigated comparing with the effect of short-term mental stress by simple arithmetic task. As a result, one immune substance within saliva, immunoglobulin A, was showed as a possible stress marker for both long- and short-term stressors.

    In this paper, we propose a font automatic generation system based on collaborative filtering. The proposed system consists of Kansei converter and user interface. Kansei converter receives Kansei words and outputs parameters. In the font generation system, the parameters express the shape of the font. We propose weighted GRNN for the Kansei converter. Weighted GRNN is a new technique that takes in the principle of the collaborative filtering. The system weights a neuron by similarity between users. Kansei converter adds a random number last and outputs multiple candidates. The candidate of multiple fonts is learned in what is chosen by the user. The user interface is interactive. That means that the usage phase and the learning phase are unified. The system can learn the sensitivity of a user with a little burden by this interface. In addition, data gathering is easy for the provider of the system. The following properties about the proposed method are obtained from the experiments. (1) A user can easily make the font that is reflected the sensitivity of the user individual. (2) Data gathering for the system is easy because of the unified user interface. The user evaluation of the proposed system is better than the conventional system.

    Today, the opportunity to appreciate visual contents on the device of various sizes, such as a large theater, a cellular phone, etc. has increased, and techniques in consideration of environment and KANSEI are required. In order to perform KANSEI evaluation of visual contents, one of typical methods is Semantic Differential Method. However, KANSEI evaluations between bipolar and unipolar method may differ. In this paper, we investigate KANSEI evaluation of 5 types visual contents by changing the reproduction color, camera work and display size. In addition, we investigate bipolarities of stimulus words and effectiveness of unipolar method.

    A lot of enterprises are requesting the production system for which it appeals to the sensibility now. Therefore, all people's eyes are focused on the key word of “Customer Experience”. However, the experience model is not enough in the point of practical application. A concrete explanation of the idea how the enterprise should create customer experience value is insufficient. In this study, we thought “Customer Experience” to be “Entertainment value”. And, the Johnny's theatrical agency that was the enterprise of excellent was taken up as an object of study. We consider the creation of “Entertainment value” by using the case with kansei value that the TV performer of Johnny's creates.

    When touching an object, the forefinger pad is deformed based on the hardness of the object, and we consider that slight deformation influences hardness sensation. To clarify the influence of deformation of forefinger pad on hardness sensation, we compared hardness sensation in two conditions with different deformation of the forefinger pad by the method of successive categories. Fourteen elastic test pieces with different hardness were evaluated by eleven subjects based on seven stages of hardness sensations (extremely soft, fairly soft, slightly soft, neither, slightly hard, fairly hard, extremely hard) for the conditions of direct touching of test pieces or touching using an acrylic plate. This results indicated that subjects were capable of perceiving slight differences in hardness within three categories (fairly soft, slightly soft, and fairly hard) for direct rather than indirect touch. Deformation of the forefinger pad based on the hardness of an object may thus influence hardness sensation when the hardness of an elastic object is classified into these three categories.

    This paper describes effect for human feelings by using a swing chair synchronized with moving pictures. The relations between human KANSEI and swing angles, pitching and rolling, were examined by using the swing chair and the moving pictures. The 12 KANSEI factors were measured under the conditions of various swing parameters: swing frequency, swing angle of swing chair, and swing angle of screen image. Feelings of powerful and interest were increased as the swing angle and the swing frequency of the swing chair become higher. Furthermore, by adding smaller swing angle of the swing chair, the powerful and the interest feelings were increased.

    This paper focuses on the cultural background between Vietnam and Japan in technology transfers and international academic/industrial partnerships, especially collaboration among universities and companies in Vietnam and Japan, possibility of conflict of interest occurring, and mutual understanding between Vietnam and Japan. As a result, we conclude that it is possible that collaboration among universities in Vietnam and Japan and Vietnamese companies works effectively. With regards to conflict of interest, Vietnamese are more critical to conflict of interest than Japanese, and rules must be established. It is important for Japanese to learn the conversation and to respect the feelings of Vietnamese. Concerning the types of support, educational program for intellectual property and introduction of hardware are requested.

    We investigated the acoustical characteristic of the sounds of crickets and its physiological and psychological effect on Japanese people. The sounds of crickets belonging to Family Grylloidae were grouped into 3 clusters by using the acoustical characteristics of the sounds. For this study, 3 Grylloidae species and 2 Tettigoniidae species were selected, and the sounds were recorded in a dark room. The psychological effect, i.e., pleasantness, was investigated by administering a questionnaire, which was based on the Semantic differential (SD) method. The comfort provided by the sounds was estimated on the basis of the findings on electroencephalograms in terms of an increase in the alpha wave. From the results of the questionnaire, people preferred the sound of crickets belonging to Family Grylloidae, rather than to those of crickets belonging to Family Tettigoniidae. It seemed that there was a deep relationship between the generation of alpha wave and the duration of the silent time within the sequential sounds. On the other hand, the rate of alpha wave increase in each species was not in good agreement with the results of the questionnaire, suggesting that further study is requires to understand the relationships between psychological and physiological effect on the human's Kansei. Finally, we proposed the effective presentation of the pleasant cricket sounds.

    More and more video users now enjoy the sense of a “special seat” given by modern video devices thanks to the development of broadcast technology and digital technology. There are also increasing opportunities for users to view video presentations in the work environment. When different types of video equipment are used, however, their technical characteristics affect how the content is displayed; it is not uncommon for viewers of the presentations under different media to be left with differing impressions. This research is intended to point out directions for development of systems which will provide viewers with the same sensory impressions of any given video production, regardless of the mode of viewing. The present report focuses on 2 projectors of differing types. The projectors were adjusted to minimize differences in color reproduction; the investigation examined sensory assessments of the perceived differences between the display modalities.

    Image retrieval systems are widespread in areas such as online shopping, etc. Usually images are retrieved according to the annotated texts. This text image retrieval needs a lot of load of time and effort to annotate the images. As an effective retrieval system, Kansei image retrieval system is proposed. By Kansei retrieval system we can retrieve images based only on adjective but not on noun. This fact leads limited use of Kansei retrieval systems in online shopping area. One of our main aims of this paper is to propose a noun and adjective based image retrieval system. In order to propose noun based image retrieval method, we apply MTS method, since MTS method is a useful pattern information processing method by the use of Mahalanobis distance. We construct image retrieval system for apparel products, and investigate accuracy of noun retrieval and fitness of noun and adjective based retrieved image.

    Recently, there are several kinds of values with the diversification of individuality in market. Some of the values supported by few people, which is called “minority group”, at present have possibility to grow to majority groups in future with the change of historical background or people's sensitivity. It is effective and important for the market analysis to find out these minority groups at early stage. Companies often carry out questionnaires to develop marketing strategy or design new products, which is a chance to find them. In conventional methods, respondents of a questionnaire are classified based on the attributes such as gender, age and so on, and then the classified groups are analyzed or compared one another. Though the conventional analysis is effective to grasp the overall tendency of the evaluation data, it is difficult to find out minority groups because of the diversity of individuality. On the other hand, the authors have proposed the clustering methods based on the tendency of the answer of the questionnaire. This paper proposes a new method to visualize the evaluated data based on both the evaluation value and the correlation of them and to cluster respondents interactively on the visible space. This paper applies the proposed method to a web questionnaire data and shows that this method effectively supports to find out minority groups with the analysis for them.
