The issue of care workers working for elder persons is becoming increasing important. Since their working conditions and environments have been uncomfortable and sometimes poor, many soon quit, ...leading to a shortage of care workers. The purpose of this article is to examine the causal process of turnover intention, focusing on factors leading to care worker burnout, and thereby to suggest remedial policies. We issue a challenge to build a new analytical model to investigate care worker intentions and behavior. In this study we conduct research covering 203 care workers in Fukuoka Prefecture and analyze the structure of burnout and the background of turnover behavior by personal credo/value, characters (Big Five), organizational commitment, the gap between expectations and reality, and role conflict with superiors, clients, and coworkers.
Japanese fauna of the intertidal rove beetle of tribe Liparocephalini Fenyes, 1918 is reviewed and six genera and 26 species are recognized. A new genus, Rotundicephala Tasaku, Ono & Maruyama, gen. ...n., is described to include R. pacifica (Sawada, 1971) comb. n. (type species; transferred from Diaulota), R. koreana (Yoo & Ahn, 2021), comb. n. (transferred from Diaulota) and R. koheii Tasaku, Ono & Maruyama, sp. n. Four new species are described: Diaulota decipiens Tasaku, Ono & Maruyama, sp. n., which has been confused with D. aokii, D. orientalis Tasaku, Ono & Maruyama, sp. n., R. koheii Tasaku, Ono & Maruyama, sp. n., and Paramblopusa sumikawai Tasaku, Ono & Maruyama, sp. n. Three species, Amblopusa brevipes Casey, 1893, D. submarina Ahn, 2023 and R. koreana, are reported from Japan for the first time. We provide keys to genera and species, illustrations of mouth parts and diagnostic characteristics of each genus, and diagnostic characteristics and illustrations of the genitalia of almost all species. Biogeographical patterns of Diaulota and Rotundicephala gen. n., and the tribal range and monophyly of Liparocephalini are discussed. Three genus-group: the Liparocephalus genus-group, the Amblopusa genus-group, and the Paramblopusa genus-group are recognized in the tribe, but Baeostethus Broun, 1909 known from New Zealand is regarded as incertae sedis. The genera Ashella Klimaszewski, 2020 and Ianmoorea Ahn, 2006 are excluded from Liparocephalini.
A new species of the intertidal rove beetle genus Bryothinusa, B. japonica sp. nov. is described, and B. koreana Ahn Jeon, 2004 is recorded from Japan for the first time. These species are ...illustrated and compared with similar species. A key to the Japanese Bryothinusa species and a checklist of the known Bryothinusa species are provided.
The density of singlet delta oxygen O2(a1Δg) produced under low-pressure mercury lamp irradiation in an oxygen–nitrogen mixture is measured by infrared optical emission spectroscopy and compared with ...the results of simulations. A 30-cm-long lamp, whose radiation power is 1.9W for 185nm light and 12.2W for 254nm light, is irradiated in a cylindrical reactor of 8cm inner diameter with an O2(1–20%)/N2 flow of 3.75–10L/min. The measurement shows that the O2(a1Δg) density at the reactor outlet is approximately 1–2ppm under all experimental conditions, regardless of the O2 concentration and the flow rate. The simulation reproduces the measurement results well and within an error of 50%. On the basis of the simulation model, the O2(a1Δg) density can be simply expressed as O2(a1Δg)=2.7×10−3I/(1+4.2×10−4O2/O3), where I is the illuminance at 254nm. When O3/O2≫4.2×10−4, O2(a1Δg) can be approximated as 2.7×10−3I, which is independent of parameters other than I, as shown by the measurement. The O2(a1Δg) densities calculated using these simple expressions agree with the measured O2(a1Δg) densities within an error of 80%.
Severe oral mucositis caused by chemo- and radio-therapy is a common adverse event in patients with cancer. In this study, we investigated the development of an indomethacin mouth wash(IM-MW)as a ...novel approach to treat pain due to oral mucositis.
We examined the appropriate preparation methods for IM-MW with suitable stability. IM- MW was made from bulk IM, controlled release IM capsules, and IM capsules. Dissolution in water was tested at water temperatures of 70℃, 90℃, and 98℃(n=3), and with a shaking time of 30 or 60s(n=3). We determined the IM concentration in IM-MW by HPLC-UV analysis(n=5)at time points between just after preparation and day 7, to estimate the shelf- life at 4℃ and 25℃.
At 70℃, bulk IM did not dissolve, but at 90℃ and 98℃, bulk IM, controlled release IM capsules, and IM capsules all dissolved effectively. Shaking times of 30 and 60s were sufficient to dissolve bulk IM, controlled release IM capsules, and IM capsules. The stability of IM in IM-MW was 98.6±2.8%(bulk), 99.2±6.0%(controlled release capsule), and 98.5±6.0%(capsule)over 7 days at 4℃. However, at 25℃, IM stability in IM-MW decreased to 95.3±1.8% (bulk), 86.1±4.8%(controlled release capsule), and 83.6±1.6%(capsule).
In this study, we identified the most suitable method for the preparation of IM-MW(90℃, shaking time of over 30s). IM-MW was stable when stored at 4℃ for at least 7 days after preparation.
Epitaxial thin films of TmFeCuO sub(4) with a two-dimensional triangular lattice structure were successfully grown on yttria-stabilized-zirconia substrates by pulsed laser deposition and ex situ ...annealing in air. The films as-deposited below 500 degree C showed no TmFeCuO sub(4) phase and the subsequent annealing resulted in the decomposition of film components. On the other hand, as-grown films deposited at 800 degree C showed an amorphous nature. Thermal annealing converted the amorphous films into highly (0 0 1)-oriented epitaxial films. The results of scanning electron microscopic analysis suggest that the crystal growth process during thermal annealing is dominated by the regrowth of non-uniformly shaped islands to the distinct uniform islands of hexagonal base.
