Cesium lead iodide （CsPbIa）, in its black perovskite phase, has a suitable bandgap and high quantum efficiency for photovoltaic applications. However, CsPbI3 tends to crystalize into a yellow non-perovskite phase, which has poor optoelectronic properties, at room temperature. Therefore, controlling the phase transition in CsPbI3 is critical for practical application of this material. Here we report a systematic study of the phase transition of one-dimensional CsPbI3 nanowires and their corresponding structural, optical, and electrical properties. We show the formation of perovskite black phase CsPbIa nanowires from the non-perovskite yellow phase through rapid thermal quenching. Post-transformed black phase CsPbI3 nanowires exhibit increased photoluminescence emission intensity with a shrinking of the bandgap from 2.78 to 1.76 eV. The perovskite nanowires were photoconductive and showed a fast photoresponse and excellent stability at room temperature. These promising optical and electrical properties make the perovskite CsPbI3 nanowires attractive for a variety of nanoscale optoelectronic devices.

AIM：To compare the surgical outcomes of trabeculectomy with ex-PReSS implant and Ahmed glaucoma valve（AGV） implantation. MeTHODS： Patients who underwent trabeculectomy with ex-PReSS implants or AGV implantation separately were included in this retrospective chart *** outcome measures were surgical failure and *** was defined as intraocular pressure（IOP）〉21 mm Hg or 〈5 mm Hg on two consecutive visits after 3mo,reoperation for glaucoma,or loss of light *** that had not failed were considered as complete success if they did not required supplemental medical ***： A total of 64 eyes from 57 patients were included： 31 eyes in the ex-PReSS group and 33 eyes in the AGV *** mean follow-up time was 2.6 ±1.1y and 3.3±1.6y,*** in the AGV group had significantly higher baseline mean IOP（P =0.005）,lower baseline mean visual acuity（VA）（P =0.02）,and higher proportion of patients with history of previous trabeculectomy（P 〈0.0001）.Crude failure rates were 16.1%,n =5/31 in the ex-PReSS group and 24.2%,n =8/33 in the AGV *** cumulative proportion of failure was similar between the groups,P =*** proportion of eyes that experienced postoperative complications was32.3% in the ex-PReSS group and 60.1% in the AGV group（P =0.0229）.CONCLUSION： Trabeculectomy with ex-PReSS implant and AGV implantation had comparable failure *** AGV group had more post-operative complications,but also included more complex cases with higher baselinemean IOP,worse baseline mean VA,and more previous glaucoma ***,the results are limited to the cohort included in this study.

The present study aimed to clarify the current status and awareness of psychological preparation for children undergoing medical procedures in pediatric nursing in Japan as compared with that in Germany. An original questionnaire about the current status and awareness of psychological preparation for children in hospitals was distributed by mail to nurses’ working on Japanese pediatric wards in 2010. The same questionnaire, translated into German, was distributed to nurses working on German pediatric wards via the internet in 2010. A large majority of respondents strongly agreed that children have a right to informed consent. German nurses expressed a longer-term viewpoint on the effects of preparation than Japanese nurses. Japanese nurses recognized a greater need for improvement in their duties than German nurses. The results suggest that we should consider our own country’s nursing practices and need for improvement, but also learn from studies of other countries to address each culture and medical situation appropriately.

This paper reports on an ethnographic inquiry into the linguistic and sociocultural affordances available to english and Japanese foreign language learners through their engagement in a social learning space at a Japanese university. By social learning space we refer to a facility in which students come together in order to learn with and from each other in a non- formal setting. To explore the social learning dynamic in this environment, we carried out a longitudinal ethnographic inquiry. Data came primarily from interviews with learners and administrators, supported by participant-observations. A thematic analysis of the data, informed by ecological and community of practice perspectives, pointed to the emergence of a community of learners and revealed how closely the affordances were connected with the emergent community. In this paper we report on the findings related to the affordances which gave rise to language learning opportunities, the relationship of these affordances to the conditions which supported the development of a community of learners, and the role of learner autonomy in regard to these two interrelated phenomena.
