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.展开更多

In this study, to understand the current practice and application of psychological preparation, using “explaining medical information to a child” as an indicator of respect for children’s rights, we investigated the effect of psychological preparation since 2002. The present study aimed to clarify the current status and awareness of psychological preparation for children undergoing medical procedures in pediatric nursing in Japan. An original questionnaire regarding psychological preparation for children in hospitals was sent by mail to nurses who were working in Japanese pediatric wards in 2010. Based on results from a previous study, nurses’ awareness of psychological preparation for children undergoing medical procedures seems to have improved. However, it was evident that nursing staff working in mixed wards require more specialized knowledge regarding child care, especially in terms of preparation. Furthermore, Japanese nurses recognized a need for improvement concerning their duties. It was also clear that the meaning of preparation remains ambiguous for many nurses. These results suggest that preparation has both psychological and ethical meanings.展开更多
The thiono-thiolo allylic rearrangement of O-allyl-O-aryl-O-ethyl thionophosphates(1a-j) adsorbed on SiO2 afforded the corresponding O-aryl-O-ethyl-S-allyl thiolophosphates (2a-j) in good yields.

All these catalysts have been investigated by reaction tests and some physico-chemical characterizations such as BET, H2 chemisorption, catalytic grain crushing strength, NHa-TPD and TPO analyses. Test results showed that the addition of alumina binder could enhance the mechanical strength of catalyst evidently. Moreover, the different preparation procedures not only modified the characteristics of both acid and metal functions but also affected the coke deposition on the catalysts. Among these catalysts studied, the catalyst prepared by impregnation followed by the agglomeration of alumi- na binder had exhibited the highest catalytic activity and stability compared with other catalyst samples undergoing different preparation procedures. The possible reason may be attributed to the highest metallic dispersion and the strong interactions among Pt, Sn and the support.展开更多
