Abstract

The demand for higher frame rates and resolutions on display panels remains strong as the gaming market has expanded in recent years. To make new use of these display panels, we have developed a privacy display in combination with active retarder. We made a prototype using high frame rate scanning backlight system and achieved the 4% level for the crosstalk ratio. [ABSTRACT FROM AUTHOR]

Abstract

We have developed a one-dimensional simulation code for laser shock processing with an atomic model code, an equation of state code, and a laser ablation peening code, in order to calculate laser-plume interactions during laser shock processing. We calculated the temporal changes of some energy ratios [e.g., the ratio (α′) of the thermal energy of a plume to an incident laser energy] and physical quantities, such as electron temperature, ion temperature, absorbed laser power density, and plume pressure under various laser parameters at the laser wavelengths of 355, 532, and 1064 nm. In the case of shorter pulse durations less than 10 ns, a peak plume pressure can be predicted by using α′ of ∼0.25 for 1064 nm and ∼0.40 for 355 and 532 nm below the power density threshold, at which plume pressures start to saturate. These values of α′ were consistent with those obtained in the previous experiments. In the case of longer pulse durations more than 10 ns, α′ for 1064 nm increased up to ∼0.45 at 15 GW/cm2 and an enhanced plume pressure would generate due to plasma absorption via inverse bremsstrahlung absorption in the partially ionized region far from the initial surface of the metal and due to heat conduction of the thermal energy of the plume near the initial surface of the metal. Thus, we showed the validity of our one-dimensional simulation code for laser shock processing and will investigate laser-plume interactions using double pulses during laser shock processing in the future.

Abstract

Although microbial contamination of ice machines has been reported, no previous study has addressed microbial contamination of ice produced by machines equipped with activated charcoal (AC) filters in hospitals. The aim of this study was to provide clinical data for evaluating AC filters to prevent microbial contamination of ice. We compared microbial contamination in ice samples produced by machines with (n = 20) and without an AC filter (n = 40) in Shunan City Shinnanyo Municipal Hospital. All samples from the ice machine equipped with an AC filter contained 10-116 CFUs/g of glucose nonfermenting gram-negative bacteria such as Pseudomonas aeruginosa and Chryseobacterium meningosepticum. No microorganisms were detected in samples from ice machines without AC filters. After the AC filter was removed from the ice machine that tested positive for Gram-negative bacteria, the ice was resampled (n = 20). Analysis found no contaminants. Ice machines equipped with AC filters pose a serious risk factor for ice contamination. New filter-use guidelines and regulations on bacterial detection limits to prevent contamination of ice in healthcare facilities are necessary., Introduction Virtually all hospitals are equipped with machines to provide ice for beverages and for use in ice packs. Microbial contamination of ice machines poses severe health risks to patients [...]

Abstract

本論文ではまず京都大学の学生相談機関であるカウンセリングルーム(学生懇話室・カウンセリングセンター時代を含む)におけるグループ活動の変遷について確認を行った結果, グループ活動の目的や形式が変化していたことが確認された。次に, 他大学の学生相談機関で実施しているグループ活動についてホームページでの確認を行い, 184の学生相談機関の約3 分の1 の大学で実施していることが分かった。これらを踏まえ, 2019年度からカウンセリングルームで開始したグループプログラム「くすくす」について, 実施に至る背景や実際の活動状況について報告した。今後の課題として, 本グループプログラムの効果をどのように検証し, また部局等に発信し, 連携していくかなどを論じた。
