The purpose of this study was to grasp the actuality of undergraduates question behaviors in classes, and to examine factors affecting them. In study 1, observation of undergraduates' question behaviors was conducted. As a result, the question behaviors were classified into four styles: 1.voluntary style, 2.not-voluntary style, 3.after-class style, 4.no-question. In study 2, the questionnaire about the usual question behavior, the reason why they don't ask voluntary in classes, and factors that seemed to affect question behaviors was conducted. Subjects were 292 undergraduates. Results were as follows: (a) the tendency that students didn't ask question voluntary in classes, but ask question actively after classes was founded, (b) not only the individual characteristics, but also the class situation affected the undergraduates' question behaviors. Result of this study suggested that the undergraduates' question behaviors were affected by the existence of other students and the mood of class strongly. so that students didn't ask questions voluntary in classes.

Background:The prognostic impact of atrial fibrillation (AF) among patients at high risk for heart failure (HF) remains unclear. In addition, there is no risk estimation model for AF development in these patients.Methods and Results:The present study included 5,382 consecutive patients at high risk of HF enrolled in the CHART-2 Study (n=10,219). At enrollment, 1,217 (22.6%) had AF, and were characterized, as compared with non-AF patients, by higher age, lower estimated glomerular filtration rate, higher B-type natriuretic peptide (BNP) level and lower left ventricular ejection fraction. A total of 116 non-AF patients (2.8%) newly developed AF (new AF) during the median 3.1-year follow-up. AF at enrollment was associated with worse prognosis for both all-cause death and HF hospitalization (adjusted hazard ratio (aHR) 1.31, P=0.027 and aHR 1.74, P=0.001, for all-cause death and HF hospitalization, respectively) and new AF was associated with HF hospitalization (aHR 4.54, P<0.001). We developed a risk score with higher age, smoking, pulse pressure, lower eGFR, higher BNP, aortic valvular regurgitation, LV hypertrophy, and left atrial and ventricular dilatation on echocardiography, which effectively stratified the risk of AF development with excellent accuracy (AUC 0.76).Conclusions:These results indicated that AF is associated with worse prognosis in patients at high risk of HF, and our new risk score may be useful to identify patients at high risk for AF onset.

This study investigated the long-term transition of community conflict caused by cat breeding, especially the case of `community cats' activity in Isogo, Yokohama-city. In this practice, residents treated `cat problem' as `residents-relation problem' thoroughly to manage community conflict, and established "guideline" including two divided claims (like/dislike cats). To examine the features of the long-term practice, content analysis on volunteers' annual reports from 2001 to 2011 was performed. The results suggested that volunteers faced many difficulties during the `community cats' activity and that appropriate communication in a community is vital in conducting the `community cats' activity.

This study presents a new method for designing self-deploying origami using the geometrically misaligned creases. In this method, some facets are replaced by “holes” such that the systems become a 1-DOF mechanism. These perforated origami models can be folded and unfolded similar to rigidfoldable(without misalignment) models because of their DOF despite the existence of the misalignment. Focusing on the removed facets, the holes will deform according to the motion of the frame of the remaining parts. In the proposed method, these holes are filled with elastic parts and store elastic energy for self-deployment. First, a new extended rigid-folding simulation technique is proposed to estimate the deformation of the holes. Next by using the above technique, the proposed method is applied on arbitrary-size quadrilateral mesh origami. Finally, by using the finite-element method, the authors conduct numerical simulations and confirm the deployment capabilities of the models.

The distribution of latrines of the raccoon dog, Nyctereutes procyonoides, was examined from July 2006 to December 2007 in the Imperial Palace grounds, Tokyo, Japan. The raccoon dog is accustomed to defecate at fixed locations, forming holding latrines; thus the distribution of latrines is a good indicator of their abundance. The results suggest that the latrines are widely scattered in the study site, but are more dense in the Fukiage area, where an old-growth broad-leaved forest is established. The latrine sites are used more frequently from September to December, as the number of fresh feces increased in the autumnal season. To examine the seasonal food changes of the raccoon dogs, 10 pieces of feces from some latrines were collected every month and analyzed the indigestible contents in the sampled feces. The food items identified consisted of animal, plant and man-made materials, suggesting that the raccoon dogs were highly omnivorous. The animal materials found from the feces included mammals (4% of total feces), birds (37%), reptiles (2%), amphibians (3%), insects (95%), chilopods (56%), isopods (2%) and gastropods (12%). Invertebrates were the most abundand food item throughout the year. Three coleopteran families, the Carabidae, Staphylinidae and Scarabaeidae, accounted for a large proportion of the insects and they showed seasonal fluctuations. These suggest that the raccoon dogs fed on them as major animal food resources in the study site, and perhaps the seasonality is related to the temporal changes of availability of the insects. The majority of plant materials found in the feces was a variety of seeds, suggesting that the raccoon dogs fed on berries and fleshy fruits throughout the year. The occurrence of seeds decreased from March to April, which coincided with a low availability of fruits. The seeds found in feces were categorized into three types : (1) the short-term berry type including Prunus (Cerasus) spp., Moms spp., Rubus hirsutus and Machilus thunbergii, which occurred only a short term after their fruiting periods ; (2) the long-term berry type, including Celtis sinensis, Aphananthe aspera and Swida controversa, which occurred continuously for three or more months after the fruiting periods ; (3) the acorn type, including Castanopsis spp., Quercus spp. and Ginkgo biloba, which occurred in early spring (January to April) when the other fruits are scarce. The seasonal change of the three fruit types implies that the raccoon dogs consume the available fruits in relation to the successive fruiting periods. The proportion of artificial materials found in the feces was considerably lower than in previous studies carried out in the suburbs of Tokyo, suggesting that the raccoon dogs in the study site strongly depend on natural foods. Most of the natural food items were native to Japan since the past Edo period. Thus we conclude that the preservation of biodiversity in the Imperial Palace grounds was essential for the re-colonization by the raccoon dogs of the Tokyo metropolitan area after the 1970s.

トイレの便器にセンサを組み込むことで,ユーザの生体情報を日常的に取得し,健康管理などに応用できるようになった.トイレは多くの場合,複数人が共用するため採取した生体情報をユーザごとに分類する必要があるが,カメラや音声,体重計による個人識別はプライバシの観点から適切ではない.タッチパネルなどの機器を設置して操作することでの個人識別も可能であるが,本来不要な操作であるため操作を忘れることもある.そこで本論文では,トイレで自然に行われる動作であるトイレットペーパの巻き取りの個人差に着目し,芯に角速度センサを設置したトイレットペーパの回転特性から個人を識別する手法を提案する.評価実験により提案システムの有効性を確認したところ,識別精度は実験室環境において5人から1人を識別する場合に83.9%,実環境において5人から1人を識別する場合に69.2%となった.さらに,提案手法を用いて,体調管理を推進するライフログアプリケーションと,トイレットペーパの使いすぎを抑止するアプリケーションを実装した.

It is proposed that near-vision acuity tests be conducted in kindergartens and nurseries throughout the country and that infant medical checkups should also be carried out. This will allow early detection of and timely treatment for children with amblyopia. The younger the age at which these tests are carried out, the more effective they will be. If amblyopia is detected and treated by the age of 3, most children will be able to complete their treatment before reaching school age. This will enable them to begin their school life without being burdened by poor eyesight, and contribute to a society in which all children have equal access to compulsory education. To bring about that end, the introduction of "reliable" visual acuity tests over a short time is necessary. I considered the best form of visual acuity test from the standpoint of both the infant to be tested and that of the teacher carrying out the test. In order to ensure "reliability", it is necessary to use the Landolt Ring eye-mark, which meets definitions of eyesight. In addition, a picture-based eye-mark is recommended, as it is more likely to gain the understanding of the infant being tested. Avisual acuity test will be more effective if infants have already grown accustomed to the Landolt Ring during play. This picture book was devised with that aim in mind.

疑似乱数生成の研究は古くからあり,偏りのなさや周期の長さ,生成速度などの改良が進められてきた.メルセンヌツイスタなど最近の手法は数学的な意味で真の乱数に十分近いと言え,確率的最適化やモンテカルロ法などさまざまに応用されている.テレビゲームでも疑似乱数が必要になることは多く,例えばすごろくではサイコロの目をコンピュータが決めなければならない.このとき,出た目およびその系列によっては,プレイヤはそのサイコロの目が自分に都合の悪いようにコンピュータに操作されていると感じる.本稿では,数学的な意味で良い乱数と,標準的なゲームプレイヤにとっての自然な乱数は異なるという仮定をおき,どのような特徴を持たせれば自然に“見える”乱数が作れるのかを考察,実装する.被験者実験の結果,標準的な乱数よりも自然に見え,またすごろくで使ったときの不満が小さい乱数列を生成できていることを確認した.

着心地の良いブラジャーの設計や新しい設計システムを構築するためには,複雑に動く乳房の運動機構やブラジャー着用に伴う乳房振動特性の変化を明らかにしておくことが重要である.そこで,本研究では半透明なブラジャーを用いて,運動画像解析システムにより,ブラジャー着用時と非着用時の走行中と歩行中の乳房の動きを計測した.乳房の動きから体幹部の動きを分離し,乳房独自の振動データを抽出した後,離散フーリエ変換によって分析した.その結果,乳房の振動は歩行周期の影響を直接に受け,走行中が歩行中より,垂直方向が水平方向より大きくなった.ブラジャー非着用時の垂直方向の振幅は歩行周波数で最大となり,体幹部の運動の影響を強く受けることが分かった.非着用時の乳房振動は乳房の硬さ指標と相関が高く,柔らかい乳房が硬い乳房より振幅が大となった.ブラジャーの着用によって,乳房の振幅スペクトルに高い周波数成分が生じるようになり,測定点間の相関も低くなった.またブラジャー着用時の乳房が硬い乳房に近くなり,両者の特性が似たものとして表れた.以上のように乳房振動を分析し,その特性をとらえることができた.乳房の振動特性は,ブラジャーの着くずれや着心地に関係する問題を含み,設計に欠かすことのできない要因である.ブラジャーの設計支援システムの中で,乳房の振動特性をどのように制御するかが重要な課題である.今後は胸部の3次元形状データのモデルを利用して,運動機能性のよいブラジャー設計の技術開発につなげたいと考えている.

マイクロブログから特定の話題に対するユーザの反応を取得する技術が研究されている.マイクロブログをソーシャルセンサとして有効活用するには,ユーザごとの特性を知る必要がある.しかし,マイクロブログでは,ユーザが属性を公開していない場合が多々あるため,ユーザごとの特性を把握できない.このことから,マイクロブログのユーザ属性を推定する研究が注目されている.しかし,既存手法では,主にマイクロブログの投稿内容にのみ着目しており,リアルタイムに発信されるマイクロブログの特性を属性推定に活かせていない.そこで,本研究では,各単位時間の投稿数に基づきユーザをクラスタリングし,投稿内容,生活習慣と投稿時間帯から職業属性を推定する手法を提案する.実証実験では,投稿内容のみを使用して推定する既存手法と,時間的特徴をも考慮する本手法について比較実験を行い,本提案手法の有用性を確認した.Research is being conducted on technology to get users' reactions to specific topics in microblogs. It is necessary to know the users' characteristics in order to effectively utilize microblogs as social sensors. However, it cannot understand the users' characteristics, because user attributes are not often to the public in microblogs. For this reason, research on estimating user attributes in microblogs has been drawing attention. However, existing methods, which merely focus on the description contents in microblogs, do not take advantage of the characteristics in microblogs that transmit in real time to estimate users' attributes. This research proposes a method for classifying the users according to number of posts per unit time and estimating the occupation attributes by description contents, lifestyle and time zone of posts. Our demonstration experiments verify usability of the proposed method by comparing the existing methods of estimating merely using description contents with the proposed method of estimating using description contents and temporal characteristics.
