Sense of coherence on the relationship between COVID-19-related stress and sleep quality among nurses.

Aim: We aimed to examine the mediating effects of the Sense of Coherence (SOC) on the relationship between stress and sleep in nurses during the coronavirus disease 2019 (COVID-19) pandemic.

Methods: A cross-sectional survey targeting nurses in Chiba and Tokyo during the summer of 2021 was conducted using Google Forms. Responses were obtained using the Pittsburgh Sleep Quality Index (PSQI), the 13-item version of the SOC scale (SOC-13), and questions regarding COVID-19-related stress.

Designing a test battery for workers' well-being: the first wave of the Tsukuba Salutogenic Occupational Cohort Study.

Background: In recent years, there has been a diversification of working styles. The concept of workers' well-being is no longer limited to material wealth, such as how satisfied they are with their wages. Psychological enrichment, encompassing factors like motivation and interpersonal relationships, is also important.

Strength Assessment of Water-Glass Sand Mixtures.

For years, the chemical injection process has aided construction works by increasing the strength and water-sealing efficiency of sandy soil. Despite its growing popularity in projects, such as seismic strengthening and liquefaction mitigation, a unified understanding of how chemically treated soil develops its strength, especially under static conditions, remains elusive. Some studies have proposed that strength is derived from the tensile effects of dilatancy, where shearing of the sandy soil causes expansion, creating tension in the interstitial hydrogel and resulting in negative pressure that consolidates the soil particles.

Factors Associated With Work Engagement of Nurses During the Fifth Wave of the COVID-19 Pandemic in Japan: Web-Based Cross-Sectional Study.

Background: The COVID-19 pandemic has brought to light the prevalence of mental health issues among nurses. Work engagement (WE) is a concept that describes work-related positive psychological states and is of importance within mental health measures. There is, however, a lack of research on factors associated with the WE of nurses during the COVID-19 pandemic.
