Crystal structure, electrical properties, and mechanical response of (100)-/(001)-oriented epitaxial Pb(Mg1/3Nb2/3)O 3-PbTiO3 films grown on (100)cSrRuO 3∥(100)SrTiO3 substrates by metal-organic chemical vapor deposition

Relaxor-type ferroelectric (1-x)Pb(Mg1/3Nb2/3)O 3-xPbTiO3 (PMN-PT) films, 2-3 μm in thickness, with a PbTiO3 content (x) ranging from 0 to 1 were grown on (100) cSrRuO3∥(100)SrTiO3 substrates at 650°C by metal-organic chemical vapor deposition. The effects the x value had on the crystal structure, dielectric and ferroelectric properties, and mechanical response of these films were systematically investigated. Epitaxial growth having (100)/(001) orientation irrespective of x and the constituent phase change with x were ascertained from both x-ray diffraction reciprocal space mapping analysis and Raman spectroscopy. The constituent phase changed from a rhombohedral (pseudocubic) single phase, a mixture phase of rhombohedral (pseudocubic) and tetragonal phases, and a tetragonal single phase, with increasing x. The mixed phase region was found to exist at x=0.40-0.55, which was different from that reported for single crystals (x=0.31-0.35). The dependencies of relative dielectric constant and remanent polarization on x showed a similar trend in the case of a PMN-PT sintered body; however, the magnitudes of these values were relatively low. The effective longitudinal piezoelectric coefficient (d33,f) and the transverse coefficient (e31,f) of 100-120 pm/V and ∼-11.0 C/m2 were, respectively, calculated for a film with x=0.39, which corresponds to a larger x edge for the rhombohedral (pseudocubic) region following the engineered domain concept proposed for PMN-PT single crystals

Subaru Imaging of Asymmetric Features in a Transitional Disk in Upper Scorpius

We report high-resolution (0.07 arcsec) near-infrared polarized intensity images of the circumstellar disk around the star 2MASS J16042165-2130284 obtained with HiCIAO mounted on the Subaru 8.2 m telescope. We present our $H$-band data, which clearly exhibits a resolved, face-on disk with a large inner hole for the first time at infrared wavelengths. We detect the centrosymmetric polarization pattern in the circumstellar material as has been observed in other disks. Elliptical fitting gives the semimajor axis, semiminor axis, and position angle (P.A.) of the disk as 63 AU, 62 AU, and -14 $^{\circ}$, respectively. The disk is asymmetric, with one dip located at P.A.s of $\sim85^{\circ}$. Our observed disk size agrees well with a previous study of dust and CO emission at submillimeter wavelength with Submillimeter Array. Hence, the near-infrared light is interpreted as scattered light reflected from the inner edge of the disk. Our observations also detect an elongated arc (50 AU) extending over the disk inner hole. It emanates at the inner edge of the western side of the disk, extending inward first, then curving to the northeast. We discuss the possibility that the inner hole, the dip, and the arc that we have observed may be related to the existence of unseen bodies within the disk.Comment: 21 pages, 3 figures, published 2012 November 7 by ApJL, typo correcte

The influence of workplace environment on care managers' job stress

application/pdf本研究では介護支援専門員の職業性ストレスおよびバーンアウト，離職意図における職場環境の影響を検討した。327人の介護支援専門員が，(1)仕事のストレス判定図，(2)日本語版バーンアウト尺度，(3)職業性ストレス尺度，について回答した。調査の結果から，以下のことが明らかになった。 (1)介護支援専門員の業務の量的負担が他の職種にくらべ相対的に大きかった。(2)男女共に職場の上司・同僚の支援が健康リスクを減じて他の職種の平均以下の水準に低下させていた。(3)男女共に上司の支援が介護支援専門員の離職意図を減じていた。(4)女性介護支援専門員の職業性ストレスやバーンアウトの緩和に上司の支援が有効であった。これらの結果から，介護支援専門員のバーンアウトの予防には，仕事の量的負担の軽減と上司の支援が重要であることが示唆された。This study was to investigate the effect of workplace environment on care managers’ job stress, burnout, and turnoverintention. 327 care managers were investigated by means of self rating stress surveys and a burnout inventory. From these results, the following was found. (1) Job demands of care managers were relatively high in comparison with the other types of job. (2) Support from superiors and colleagues reduced the health risk to the level of lower than average of the other types. (3) Support of superiors reduced the intention of turnover of them. (4) Mitigation of job stress and burnout of female care managers was elicited by the support of superiors. It was suggested that the reduction of the job demands and the support of superiors were important for the prevention of burnout of care managers.原著|Original Articlesdepartmental bulletin pape
