Development of a High Definition Haptic Rendering for Stability and Fidelity

In this study, we developed and evaluated a 10kHz high definition haptic rendering system which could display at real-time video-rate (60Hz) for general VR applications. Our proposal required both fidelity and stability in a multi-rate system, with a frequency ratio of approximately 160 times. To satisfy these two criteria, there were some problems to be resolved. To achieve only stability, we could use a virtual coupling method to link a haptic display and a virtual object. However, due to its low coupling impedance, this method is not good for realization of fidelity and quality of manipulation. Therefore, we developed a multi-rate system with two level up-samplings for both fidelity and stability of haptic sensation. The first level up-sampling achieved stability by the virtual coupling, and the second level achieved fidelity by 10kHz haptic rendering to compensate for the haptic quality lost from the coupling process. We confirmed that, with our proposed system, we could achieve both stability and fidelity of haptic rendering through a computer simulation and a 6DOF haptic interface (SPIDAR-G) with a rigid object simulation engine

New Matsushiro underground cosmic ray station (220 M.W.E. in depth)

A new underground cosmic ray station has been opened at Matsushiro, Japan, and a multidirectional (17 directional channels) muon telescope has been installed at an effective vertical depth of 220 m.w.e. The counting rates are; 8.7 x 10,000/hr for the wide vertical component and 2.0 x 10,000/hr for the vertical component. Continuous observation has been performed since March 22,1984. Some details of the telescope and preliminary analyzed results of the data are presented

Report of IRPA task group on the impact of the eye lens dose limits

In 2012 IRPA established a task group (TG) to identify key issues in the implementation of the revised eye lens dose limit. The TG reported its conclusions in 2013. In January 2015, IRPA asked the TG to review progress with the implementation of the recommendations from the early report and to collate current practitioner experience. This report presents the results of a survey on the view of the IRPA professionals on the new limit to the lens of the eye and on the wider issue of tissue reactions. Recommendations derived from the survey are presented. This report was approved by IRPA Executive Council on 31 January 2017

A case of wound dual infection with Pasteurella dagmatis and Pasteurella Canis resulting from a dog bite - limitations of Vitek-2 system in exact identification of Pasteurella species

<p>Abstract</p> <p>Background</p> <p><it>Pasteurella </it>species, widely known as indigenous orgganisms in the oral and gastrointestinal floras of many wild and domestic animals, are important pathogens in both animals and humans. Human infections due to <it>Pasteurella </it>species are in most cases associated with infected injuries following animal bites. We encountered a rare case of dual infections caused by different two <it>Pasteurella </it>species occurred in a previously healthy 25-year-old female sustaining injury by a dog-bite.</p> <p>Methodology</p> <p>Exudates from the open wound of her dog-bite site, together with the saliva of the dog were submitted for bacteriological examination. Predominantly appearing grayish-white smooth colonies with almost the same colonial properties but slightly different glistening grown on chocolate and sheep blood agar plates were characterized morphologically by Gram's stain, biochemically by automated instrument using Vitek 2 system using GN cards together with commercially available kit system, ID-Test HN-20 rapid panels, and genetically by sequencing the 16S rRNA genes of the organism using a Taq DyeDeoxy Terminator Cycle Sequencing and a model 3100 DNA sequencer instrument.</p> <p>Results</p> <p>The causative isolates from the dog-bite site were finally identified as <it>P</it>. <it>canis </it>and <it>P</it>. <it>dagmatis </it>from the findings of the morphological, cultural, and biochemical properties together with the comparative sequences of the 16S rRNA genes. Both the isolates were highly susceptible to many antibiotics and the patient was successfully treated with the administration of so-called the first generation cephalosporin, cefazolin followed by so-called the third generation cephalosporin, cefcapene pivoxil. The isolate from the dog was subsequently identified as <it>P</it>. <it>canis</it>, the same species as the isolate from the patient.</p> <p>Conclusions</p> <p>To the best of our knowledge, this was the second report of a dual infection with <it>Pasteurella </it>species consisting of <it>P</it>. <it>dagmatis </it>and <it>P. canis </it>resulting from a dog-bite, followed by the first report of dual infections due to <it>P</it>. <it>dagmatis </it>and <it>P. multocida </it>in 1988. Our isolate finally identified as <it>P</it>. <it>dagmatis </it>was misidentified as <it>P</it>. <it>pneumotripica by </it>means of the Vitek 2 system. The species name "<it>P</it>. <it>dagmatis" </it>was not included in the database of the system. It is also important for routine clinical microbiology laboratories to know the limitation of the automated Vitek 2 system for the accurate identification of <it>Pasteurella </it>species especially <it>P</it>. <it>dagmatis</it>. It should be emphasized that there still exists much room for improvement in Vitek 2 system. Significant improvement of Vitek 2 system especially in the identification of <it>Pasteurella </it>species is urgently desired.</p

携帯端末を使用した演奏映像提出の現状と今後の課題

2011年度の児童学科「児童音楽Ⅰ」の授業において, 非対面指導の一環として約100名の履修者が各自の携帯端末を使って自身のピアノ演奏を録画し, インターネット上の指定サイトにアップロード提出する試みを実施した。この実践中に生じた幾つかの問題は受信側 (指導者, サーバ管理者) と送信側 (履修者) 双方に起因するが, 受信側が解決すべき点は, アップロードサイトが扱う文字コードを変更すること, アップロード中の表示をよりわかりやすくすること, 履修者の使用メディア, データ容量やアップロードの方法に標準的なガイドラインを示すことなどであった。また, 履修者も, 携帯端末とパーソナルコンピュータ (以下, PC) 間のデータ転送の方法を習得し, マルチメディアを取り扱うことへの"抵抗感"を取り払う努力をすべきである

ピアノ弾き歌い実技指導における練習映像提出併用の効果

2006・2007年の2ヵ年にわたって,対面式授業(レッスン)の時間数の不足を補うため,100名余の学生に自身のピアノ弾き歌い演奏の練習成果を録画・提出させた。その結果,演奏映像を提出するという行為は,ピアノ実技能力の向上に一定の効果があり,自己研鐙へのモチベーションを持たせることにも有効であるという結論に達した。This paper reports on the teaching of piano playing and singing, conducted over two years (FY2006 to FY2007). In order to compensate for the shortage in time available for face-to-face tuition, the Department of Pedology, Faculty of Human Development and Education, Kyoto Women's University, required one hundred or so students to practice piano playing / singing, to record the performance they had achieved through practice, and to submit the recorded video. After reviewing the trial conducted in FY2006, we changed the method of evaluating the recorded videos in the following two ways for FY2007: (1) Submission of the video no longer adds to the student's grade points, a change intended to signal that the submission is only a part of voluntary training. (2) Students were given opportunities to watch a model performance. As a result of (1), FY2007 saw a clearer correlation between the number of video submissions and the scores of performance tests than FY2006. Namely, the results suggest that a greater number of submissions by each student tended to lead to an increase in the average score in the end-of-term performance tests. This indicates that the submission of videos recording students' accomplishment motivates students to practice hard to improve their skill in performing, and effectively compensates for a shortage in the conventional face-to-face training of piano playing / singing. The opportunities mentioned in point (2) resulted in a favorable change in student's performance, particularly in playing those pieces that demand a rich expression of emotion. We find it possible to postulate that watching a model performance enables students to understand the required manner of playing on their own without being given explicit teaching. However, this hypothesis will require further analysis and verification
