Recently, wireless charging via magnetic resonance coupling has gained attention because it has the potential of efficient midrange wireless charging. Here, functions such as sensing at the transmitter and wireless communication from the target are the essential elements to realize a standard wireless charging system. Currently, the sensing and communication protocol of the hardware (i.e., the high-frequency power source and antenna configuration) compatible with wireless charging is gaining attention in terms of its cost and space reduction due to the use of common components for multiple functions. However, this protocol has the problem of narrow effective areas due to the fact that the sensing range depends on the fixed Q factor of the antenna. To overcome this problem, the concept of wide-area sensing based on a Q controllable antenna is proposed, and the effectiveness is verified through a theoretical analysis and an experiment. As a result, it is clarified that the effective area can be expanded up to a ratio of the distance g between the transmitting and receiving antennas to the inner diameter d of the antenna g/d =5.0.

現在,スマートフォンは世界中で多くの人々に利用されている.携帯電話の様々な機能が日々発展している中,音量設定に関しては依然として物理ボタンで手動設定が行われている.利用者は毎日通勤前にマナーモードを設定し,帰宅後は元に戻すなどの設定を行う必要があるため,それが手間で,常にマナーモードに設定している利用者も少なくないだろう.それでも,必要な連絡をとり逃してしまうことや,音楽が聞きたいときにはわざわざ音量を設定する必要があるなどの不便は残る.我々はこれらの課題を解決するためにインテリジェントな音量変更手法を開発している.その実現に向け,本稿では多数の被験者による実際の操作ログを収集する実験を行った.本稿では,利用者属性や音量変更を行うタイミングなどに関する考察を行った結果を報告する.Nowadays, many people use a smartphone in the world. Although many functions are improved step by step, users still manually adjust the suitable volume with hard buttons. Users set their smartphone to vibrate mode before commuting and ring mode after getting their home every day. Therefore, quite a few people always set their smartphone to vibrate mode. However, inconvenience still remains, such as to miss a necessary phone call, or to raise sound volume when the user would like to listen to music. We develop an intelligent volume adjustment method to improve such inconvenience. Towards implementation of this method, we gathered operation log of actual use by many participants. In this paper, we described the results of considerations such as considering user attributes and the right time to change sound volume.

The Lipps XY figure (Figure 2) was decomposed six line elements. Thirty two Lipps variation figures (Figure 3) contained the principal line x in the refracting line X were constructed. The apparent directions of x in these figures were estimated with parallel matching method by ten university students. The assimilation illusory effects of the accessory lines attached to x were found. These results were discussed in relation to the Metzger's theory, the apparent direction of the principal lines in the refracting lines are assimilated by the direction of the accessory lines attached to the principal lines.

During 5 years from 1959 to 1963, many reciprocal pollinations between diploid and autotetraploid rice plants using Japanese and foreign varieties were artificially carried on by hot water emasculation method, and results were as follows (Tables 2 and 3). From these crossings, besides plumply, well developed seeds, many shriveled and ill-developed seeds which contained no endosperm and were very light, 1/10~1/20 of normal seed in weight, were obtained. For convenience' sake, they were called perfect and imperfect seeds respectively. The perfect seeds set in very low percentage, that is about 1%, but they germinated well and grew to maturity. From the cytological observations, it was found that almost all of them were selfed seeds of female plants. As to the imperfect seeds, seed setting ratio was comparatively high, but they germinated in low percentage and if germinated they could not grow to seedlings. For the question whether these imperfect seeds were true hybrid seeds or parthenocarpically developed ones, some knowledges were already given in the first report. When diploid and tetraploid plants were castrated by hot water emasculation method and not pollinated afterwards, imperfect seeds did not set on diploid plants, and on tetraploid plants only 1.1% were set. This ratio was very low compared with the crossed results as shown in Tab. 2 and 3, so that the greater part of imperfect seeds in crossed case were seemed to be true hybrid seeds. Degree of seed set was typically different between reciprocal crossings, and some differences were also found between varieties. In Japanese varieties, when diploid was used as female parent imperfect seeds were less easily obtained, but in reversed crossings they were more easily obtained and more heavy in weight and germinable. On the other hand, in foreign varieties imperfect seeds were more easily obtained in the crossing 2X×4X than in reversed crossings. This tendency was very striking in the varieties O. sativa f. spontanea and Ba Thut Nuho T. T. B., but in the crosses with O. sativa f. spontanea germination was better than that in 4X×2X cross as in Japanese varieties. In foreign varieties, Ba Thut Nuho T. T. B. and Songa T. T. B. belong to the so-called Indica type, and O. sativa f. spontanea belongs to wild species. So that they were genetically different from Japanese varieties. From above facts, it was considered that the tendency of seed setting was not constant within varieties, and that this phenomenon was affected by genetic differences.1) イネの3倍体を作出することを目的として,日本稲および外国稲を用い,2倍体および同質4倍体間に相反交配を行ない,交配種子の着生について観察した. 2) 交配の結果,良く充実した完全種子は低率で約1%しか着生しなかつたが,発達が劣る不完全種子は多量に着生した. 3) 完全種子は大部分が母本の自殖種子であり,不完全種子が真正の雑種種子と考えられたので,不完全種子により相反交配および品種間の交雑成功度を検討した. 4) 交配種子の着生率は相反交配により異なり,日本稲では4x×2xが逆交配より高く,また種子重,発芽率とも大であつたが,外国稲では2x×4xの方が多く着生し,種子重には差が見られなかつた.しかし発芽率は4x×2xの方が良いようであつた.

<p>Impulsivity has been linked to traffic safety problems in many prior studies. However, it is not clear whether impulsivity, defined by the rate of discounting delayed monetary rewards, relates to drivers' problematic behavior. We investigated the relationship between the discounting of hypothetical monetary outcomes and near accident (i.e. hiyari-hatto) experiences during driving among occupational drivers. A total of 189 occupational drivers (160 men) completed the delay discounting questionnaire and hiyari-hatto experiences scale. In completing the delay discounting questionnaire, participants were asked to perform the two delay-discounting tasks, in which they chose between ¥100,000 or ¥5,000 available after some delay (from 1 month to 5 years) or a lesser amount of money available immediately. Subjective equivalence points were obtained from participants' choices on delay discounting questionnaires, from which the areas under the curve (AUC; Myerson et al., 2001) were calculated. The results indicated that the rate of discounting (AUC) was negatively correlated to near accident experiences. We discuss the need for future research on impulsivity, delay discounting, and traffic safety.</p>

1型糖尿病に対する膵島移植が国内で始まったものの,依然として大きな問題はドナー不足である.その解決手段のひとつとして,心停止下ドナーのような,条件の悪いいわゆるマージナルドナーより採取された膵臓の有効な利用である.LifePort^TM(LP)はOrgan Recovery Systems社により開発された臓器搬送用の持続冷却灌流装置であり,現在欧米において障害を伴った腎臓の搬送に臨床応用され,その有効性が確認されている.本装置はマージナルドナーから採取された臓器移植,特に虚血再潅流障害を受けやすい膵臓の保存に有用で,膵島移植の安全性や成績の向上に有効であると考えられる.本研究では,ビーグル犬を使用し,障害膵モデルより膵臓を摘出し,LPにより持続冷却灌流保存することにより,膵臓の障害が最小限に抑えられ,従来法であるUW液や2層法による浸漬保存に比べて分離膵島の収量や機能が改善でき,臨床膵島移植に応用し,成績向上に寄与することを目的とした.[方法]ビーグル犬から30分の温阻血時間をおいて全膵を摘出し,LPにて24時間持続冷却灌流保存(LP群),UW液にて24時間冷却浸漬保存(UW群),2層法にて24時間冷却浸漬保存(2層法群)し,膵島分離を行い,その形態・機能を比較検討した.[結果]形態的には,LP群でより大きく,形の良い膵島が分離できた.また,膵島収量については,純化前後でLP群においてUW群や2層法群に比べて良好であった.また,分離膵島のインスリン分泌能を評価するStatic Incubationの結果でも,LP群でUW群や2層法群に比べて良好な結果であった.[結論]心停止下ドナーよりの膵島移植を想定したモデルにおいて,LPによる障害膵の持続冷却灌流保存は,UW液や2層法による冷却浸漬保存に比べて,分離膵島の収量や機能保持に優れていることが示唆された.しかし,臨床応用のためには,さらなる保存条件や膵島分離法の改善が必要であると考えられた.

<p>Facial expressions play an important role in communication as much as words. In facial expression recognition by human, it is difficult to uniquely judge, because facial expression has the sway of recognition by individual difference and subjective recognition. Therefore, it is difficult to evaluate the reliability of the result from recognition accuracy alone, and the analysis for explaining the result and feature learned by Convolutional Neural Networks (CNN) will be considered important. In this study, we carried out the facial expression recognition from facial expression images using CNN. In addition, we analysed CNN for understanding learned features and prediction results. Emotions we focused on are "happiness", "sadness", "surprise", "anger", "disgust", "fear" and "neutral". As a result, using 32286 facial expression images, have obtained an emotion recognition score of about 57%; for two emotions (Happiness, Surprise) the recognition score exceeded 70%, but Anger and Fear was less than 50%. In the analysis of CNN, we focused on the learning process, input and intermediate layer. Analysis of the learning progress confirmed that increased data can be recognised in the following order "happiness", "surprise", "neutral", "anger", "disgust", "sadness" and "fear". From the analysis result of the input and intermediate layer, we confirmed that the feature of the eyes and mouth strongly influence the facial expression recognition, and intermediate layer neurons had active patterns corresponding to facial expressions, and also these activate patterns do not respond to partial features of facial expressions. From these results, we concluded that CNN has learned the partial features of eyes and mouth from input, and recognise the facial expression using hidden layer units having the area corresponding to each facial expression.</p>

<p>Despite the fact that induced discovery is considered to be an essential element of cognitive behavioral therapy, fundamental study of it is still uncommon. Through an empirical examination of this point, the paper notes how some previous studies have incorporated the perspective of "Total conviction" which is a core element of induced discovery. However, the factors promoting "Total conviction" are yet to be examined. Therefore, in this study, in order to model and investigate the hypothesis that an "impasse" in everyday problem-solving situations can serve to promote "Total conviction" toward problem-solving strategies, as well as inspire a sense of willingness toward a problem, we conducted a questionnaire survey of 368 university students. This resulted in a model showing a series of associations whereby the mediation of "Total conviction" by the intensity of an "impasse" exerted a positive effect on willingness to engage with a problem. This study suggests the possibility that an everyday "impasse" may be a driving factor in bringing about problem-solving behavior.</p>
