The ever-changing social implications of the COVID-19 pandemic have resulted in an urgent need to understand working environments and health status workers. We conducted a nationwide Internet-based survey Japanese workers December 2020, midst country's "third wave" infection. Of 33,087 surveys collected, 6,051 were determined invalid responses. 27,036 included study balanced terms geographical area, sex participants, type work, according sampling plan.

Abstract The X-ray binary system Cygnus X-3 (4U 2030+40, V1521 Cyg) is luminous but enigmatic owing to the high intervening absorption. High-resolution spectroscopy uniquely probes dynamics of photoionized gas in system. In this Letter, we report on an observation Cyg with XRISM/Resolve spectrometer, which provides unprecedented spectral resolution and sensitivity 2–10 keV band. We detect multiple kinematic ionization components absorption emission whose superposition leads complex line...

Training systems for occupational physicians (OPs) have existed since the Industrial Safety and Health Act was enacted in 1972. However, it is necessary to enhance them because of changes business environment Japanese corporations working patterns brought about new needs health (OH) activities. In this paper, OPs were classified into three categories; doctors who spend a part time on OH activities, i.e. "non-specialist OPs", engage activities full-time, "specialists manage corporate-wide...
