In our entertainment VR application, the user can move freely through a virtual city by using a web like SpidermanTM. In this application, the user wears a web shooter, which is a device to shoot webs, and takes aim at a target building. Then, when the user swings his/her arm ahead, a web is launched and it sticks to the target building on the screen. After the web sticks to the building, the user's arm is pulled in the direction of the target building by a pulling force feedback system, which gives the feeling of pulling to the user directly and smoothly, as if he/she were attached to an elastic string. Finally, the user moves to the target building. In three exhibitions, we surveyed the effectiveness of the application by questionnaire. We were able to confirm that a lot of users had enjoyed and were satisfied with our VR application.

This paper presents a simple font search method using an interactive genetic algorithm and similarity search. We see various types of fonts are used in many graphic designs. Various choices are available when selecting suitable fonts for presentation slides or website designs. However, the existing methods used for selecting fonts become tedious as the number of fonts increases. Our method provides an effective font search process based on visual similarity. In two experiments, we affirm that our method is effective in searching for a desired font, helping users to obtain a font suitable for an alphabetic (or non-alphabetic) character. In particular, our method allows users to search a font suitable for some words in less than half or one-third time that the user selects a font from a font list.

Yamaga Soko criticizes the lack of practicality of Neo-Confucianism and is known as a thinker who emphasizes“ daily use ”. However, if you think in detail, there is still a lot of doubt about the position of “daily use” in the philosophy of conduct. Of particular importance is the relationship between “daily use” and “the saint’s way”. To date, no studies have clarified this relationship. Looking at his understanding of the conduct of both, there is a contradiction between “the saint’s way”, which has transcendence that transcends the era, and “daily use” that has individuality depending on the era. As a clue to resolving this contradiction, this paper focused on the discussion about “Taikyoku”. In this context, Soko has criticized Zhou’s interpretation of the time of “Taikyoku”, and has developed the “Taikyoku” theory that all coexist simultaneously. The act says that “Tenchi” is also “Taikyoku”, and “Tenchi” is regarded as non-temporal. And since the saints are based on their “Tenchi”, “the saint’s way” has timeless transcendence. However, ordinary people cannot recognize “Tenchi” as a non-temporal thing, but have to recognize things in the eyes in order. As a result, the idea of time occurs in human recognition. “daily use“ is a phase in the idea of this time. Being committed to such “daily use” means that we believe we have to live in human perception, which is different from the original way of “Tenchi”. We can make such a claim because we believe that individuality and the whole are united. The “Taikyku” theory of the conduct is that all the people exist at the same time, and individual and transcendence exist at the same time as one. Therefore, living the perception of people who are only individual leads to the whole. That is why “saint ’s way” and “daily use”, which have contradictory personalities, are compatible with each other. Background of such thought is criticism of the idea that individuality and transcendence are separated temporally and individuality is only provisional. This is because such a way of thinking ignores the existence of diverse people.

Mizuhiki is a decorative Japanese cord and used for gift-money envelopes. This study shows our investigation results regarding impressions given by Mizuhiki. The advantages are the clarification for impression structure, the use of an analysis method focusing on two factors, and the development of an interactive visualization tool. First, we got five factors from factor analysis. The factors are gorgeousness, grace, favorability, novelty, and loveliness. We analyzed the relationships between two factors using a robust PCA, thereby we could know some effect factors for increasing or decreasing the impressions belonging to two factors. In addition, we developed a new visualization tool for impressions of Mizuhiki and confirmed the effectiveness via users’ experiments.

<p>運動介入が脳機能の保持・改善に重要な役割をもつことが疫学および臨床研究により提唱されてきた.運動が脳機能に及ぼす影響と関連する生理学的背景を探索する目的で,PETを活用して有酸素運動による局所脳血流量(regional cerebral blood flow: rCBF)と脳μ-オピオイド受容体系の変化を検討した.oxygen-15-labeled water(¹⁵O-H₂O)を用いたPET研究では有酸素運動中に一次運動感覚野,小脳,島皮質などで広範な脳領域でrCBFが増加することが示され,このような変化は局所の神経活動の亢進や周辺の神経受容体への影響を介して運動による神経可塑性の発現のメカニズムに関与することが推測される.¹¹C-Carfentanil を用いたPET研究では有酸素運動後に生じるポジティブな気分変化や激しい運動に伴う疲労の発現に辺縁系や下垂体に分布するμ-オピオイド受容体系が関与し,その変化には運動強度の違いや気分変化の個人間差が影響することが提示された.PETを活用した神経画像研究は,運動に伴う脳機能変化のメカニズムに関与する要因であるrCBFおよび神経受容体系の変化を検証するために有用な手法である.</p>

Recently, sizzle words have been utilized for various product packages. These words have effective communicative performance to convey deliciousness of food. In particular, onomatopoeias are used for many product packages because they can convey the texture of food sensuously. When using sizzle words, producers may consider consumers' impressions. This study aims to investigate the relations between consumers' impressions and sizzle words through an experiment. The experimental targets were four rice crackers of different hardness because their textures were directly related to consumers' impressions and some packages of rice crackers used a few sizzle words for advertising. The results of this experiment indicated five tendencies: (1) the sizzle words regarding satisfaction, tradition, and typicality, and the onomatopoeias including "<i>zaku</i>" are appropriate for an extremely hard rice cracker; (2) the sizzle words regarding lightness and comfort, and the onomatopoeias including "<i>saku</i>" are appropriate for a non-hard rice cracker; (3) the sizzle words regarding aridity, fineness, and unforgettable taste are appropriate for a slightly hard rice cracker; (4) the onomatopoeias expressing crunchy texture are appropriate for a quite hard rice cracker; (5) rough texture of food brings a sense of satiety. In addition, we performed a factor analysis using the results with 14 onomatopoeias in the experiment. The analysis results showed three factors: brittleness, irritation, and lightness. In future, we expect that these results can be utilized for guiding a choice of an appropriate sizzle word.

A fabrication method of a painless transdermal micro needle array is proposed to realize its inexpensive and mass production. In order to avoid a risk by breakage of the needle when the needle is penetrated into the epidermis, the array is made with biodegradable polymer, for example, PLA. The proposed method has the following processes, (1) a mold dies having many micro through-holes is heated over the melting point of PLA, (2) the heated mold comes into contact with surface of the PLA plate, (3) the melted PLA is poured into the through-holes, and (4) the formed PLA plate is cooled to less than the melting point and removed from the dies. It is difficult to fabricate the array device because of the ratio of needle height to the diameter is large. So, heating temperature, time of heating the plate, moving stroke of dies and demolding temperature were examined and then fabrication of high precision circular cylindrical shaped needle array became possible.

A new fabrication method of a painless micro needle array for high reliable vaccine delivery system through a epidermis is proposed. This method has been developed to realize the inexpensive and mass production of the needle array. For safety against the break of the needle, the needle is made with biogradable polymer (PLA). The proposed method has the following processes, (1) Si tool in a shape of micro needle array is heated, (2) tops of the needles over the Si tool are touched onto the surface of the polymer plate to melt the contacting areas, and (3) the Si tool is detached from the plate to form the needles by elongating the melted polymer. In order to make the uniform needles over the plate, temperature, touching time, and withdrawing speed of the Si tool and tolerance of the polymer plate are examined. By the optimized working conditions, keen corn-type needles having the height of about 500μm can be formed enable to penetrate into the epidermis.
