Toward the harmonization of work with treatment and prevention for patients with chronic respiratory failure.
Authors: Wada H, Fukumoto S, Tamamura K, Muto G, Ueki J, Tanigawa T Abstract Home oxygen therapy (HOT), also known as long-term oxygen therapy, is prescribed to patients with chronic respiratory failure (CRF) due to advanced respiratory diseases, as it has been shown to improve the prognosis of patients with chronic obstructive pulmonary disease (COPD). However, the therapeutic impact of HOT does not fully reflect the "socialization" of patients, which is one of the final goals of "comprehensive pulmonary rehabilitation", proposed by the Japanese Respiratory Society. Since working is one form of...

Evaluation of a proposed chair with an arm support for wiring terminal blocks on a vertical plane.
Authors: Chen HC, Liu YP, Hong WH, Lin YC, Yu CY Abstract To reduce the muscular exertion of an operator wiring terminal blocks on a vertical plane, a chair with a unique back that can be used as a back support or arm support is proposed in this study. A digital version of the chair was first developed based on anthropometric data and tested with a digital anthropometric subject using the Jack software before the physical chair was developed. To evaluate the effects of the physical chair, an experiment of wiring terminal blocks was conducted with 12 subjects to test whether the use of the arm support can reduce mus...

Work-to-family conflict rather than family-to-work conflict is more strongly associated with sleep disorders in Upper Egypt.
Authors: Eshak ES Abstract An important factor for which work and family compete is time. Due to lack of evidence, I investigated the associations between work-family conflict (assessed by the National Study of Midlife Development in the US) and sleep disorders (assessed by the Jenkins Sleep Questionnaire) in a cross-sectional study included 1,021 Egyptians aged 18-59 years. Both work-to-family (WFC) and family-to-work (FWC) were associated with reduced sleep quantity. Moreover, high WFC was associated with sleep disorders; the multivariable ORs (95% CIs) were 2.32 (1.63-3.30) in high versus low WFC, 1.09 (0.79-1.4...

Identifying shift worker chronotype: implications for health.
Authors: Hittle BM, Gillespie GL Abstract Shift workers are at risk for developing serious health issues due to short sleep. One cause of short sleep is circadian misalignment: sleep time is not synchronized with the body's natural circadian rhythms. Although circadian rhythms are strongly driven by the light/dark cycle, humans have individualized sleep time preferences (chronotypes) based on genetics, development, and external influences. Evening chronotype individuals fall asleep later than average and have a higher risk for developing various noncommunicable diseases. What is unclear is the association between c...

Unstable behavior of segmental ring under various pressures and its discrete element simulation.
Authors: Kikkawa N, Hiraoka N, Itoh K, Orense RP Abstract In February 2012, a serious accident which resulted in five fatalities happened during a TBM-tunnel construction under the seabed in Japan. The cause of the accident appeared to be due to the Key-segment slipping out of the segment ring by the thrusting tailskin (wire brushes) of the TBM into the segment ring. This resulted in the collapse of the rings, causing the seabed ground and seawater to flow into the tunnel. We investigated how thin and thick segments without any circumferential joints behave under isotropic and anisotropic pressures using small-scal...
