定常実験における超広帯域実時間データ収集

The ultra-wideband real-time data acquisition (DAQ) system has started its operation at LHD steady-state experiments since 2004. It uses CompactPCI standard digitizers whose acquisition performance is continuously above 80 MB/s for each frontend, and is also capable of grabbing picture frames from high-resolution cameras. Near the end of the 8th LHD experimental period, it achieved a new world record of 84 GB/shot acquired data during about 4,000 s long-pulse discharge (#56068). Numbers of real-time and batch DAQ were 15 and 30, respectively. To realize 80 MB/s streaming from the digitizer frontend to data storage and network clients, the acquired data are once buffered on the shared memory to be read by network streaming and data saving tasks independently. The former sends 1/ thinned stream by using a set of TCP and UDP sessions for every monitoring clients, and the latter saves raw data into a series of 10 s chunk files. Afterward, the subdivided segmental compression library“titz" is applied in migrating them to the mass storage for enabling users to retrieve a smaller chunk of huge data. Different compression algorithms, zlib and JPEG-LS, are automatically applied for waveform picture and data, respectively. Newly made utilities and many improvements, such as acquisition status monitor, real-time waveform monitor, and 64 bit counting in digital timing system, have put the ultra-wideband acquisition system fit for practical use by entire stuff. Demonstrated technologies here could be applied for the next generation fusion experiment like ITER

授業評価と保育所保育実習との関係についての予備的研究 : 授業「乳児保育II」の改善のために(創刊二十五周年記念号)

本研究では、演習「乳児保育II」の授業評価と乳児保育実習との関係を検討した。授業評価として、授業担当者は複数の評価方法で学生アウトカム評価を行い、学生は授業評価を行った。乳児保育実習をした学生の88%がこの授業に満足しており、「A」評価を受ける学生が乳児保育実習をしなかった学生より多かった。実習体験が授業で学んだ知識・理解と技能・実践力をより深めることが示された。In this study, we examined the relationships between the course evaluations in a seminar "Care for Infants and Toddlers II" and the practice of caring for them in Day Care Centers. For the course evaluations, the teachers evaluated the students\u27 outcomes with plural assessment methods and the students evaluated this course. Eighty-eight percent of the students who experienced the practice of caring for infants and toddlers were satisfied with this course, and more students got the Evaluation "A" than those who didn\u27t. It was shown that the practice of caring enhanced the knowledge/understanding and skills/performances of students in this seminar
