While the number of patients suffering from acute and chronic renal failure has been steadily increasing every year, the mortality rate is not improving. For the purpose of improvement on the quality of life and mortality of renal disease patients, we employ the hemofiltration principle to treat the end-stage renal disease patients. Hemofiltration equipment can be installed without additional plumbing and electrical power construction;operated only with several pre-packaged fluid bags without a huge water treatment facility. This paper describes the development of portable renal treatment equipment based on hemofiltration treatment, Carry-on Pulse Artificial Kidney (C-PAK), and reports the results of animal test using the equipment. The web-based remote monitor/control system for C-PAK is introduced also. We expect that our portable hemofiltration device for chronic renal failure patient would be an alternative for conventional hemodialysis machine and a solution to home renal treatment.

In this work, the photoluminescence（PL） of NaScP2O7：Eu^2＋ and NaScP2O7：Eu^2＋,Mn^2＋ was investigated. Phase purity was checked using X-ray powder diffractometry（XRD）. PL excitation and emission spectra were recorded to elucidate the PL properties of NaScP2O7：Eu^2＋ and NaScP2O7：Eu^2＋,Mn^2＋. Furthermore, fluorescence lifetime measurements were performed. PL and lifetime measurements were carried out from 10 to 525 K. Moreover, the Eu^2＋ site occupation was discussed. It turned out that the incorporated Eu^2＋ ions substituted for Na＋ site and occupied two different sites. Temperature dependent PL measurements indicated the emission intensity decreased with increasing temperature due to temperature quenching in NaScP2O7：Eu^2＋. Fluorescence lifetimes of Eu^2＋ in NaScP2O7：Eu^2＋ almost did not change with a decay constant τ=~0.53 μs in the temperature range of 10–280 K, and then shortened due to temperature quenching. The luminescent lifetime reached ~0.05 μs at T=525 K. Finally, it was found that energy transfer occurred from Eu^2＋ to Mn^2＋ in co-doped NaScP2O7：Eu^2＋,Mn^2＋.
A short ***-style design thinking project was offered to first-year engineering students as an option in an introduction to engineering course. Using the Stanford *** bootcamp bootleg as the guideline, students went t...
