For a narrow-brand seismograph with a flat response range limited, it cannot precisely record the signal of a ground motion and output the records with the low-frequency components cut down. A transfer function is usually used to spread the spectrum of the narrow-brand seismic records. However, the accuracy of the commonly used transfer function is not high.

To address the problem of large deformations in weak surrounding rock tunnels under high ground stress, which cause damage to initial support structures, this study proposes a novel type of circumferential pressure-relief joint based on the concept of relieving deformation pressure of the surrounding rock. Key parameters of the pressure-relief joint, such as initial bearing capacity peak, constant bearing capacity, and allowable pressure-relief displacement, were obtained through numerical simulations and laboratory experiments. A comparison was made between the mechanical characteristics of rigid joints and the new type of pressure-relief joint.

In solving the whole process of interaction between soft rock and yielding support in high-stress environments in tunnels using mechanical analysis methods, it is challenging to simultaneously satisfy both displacement coordination and static equilibrium at the contact surface between the rock and the support structure. This paper, based on the mechanical analysis of rock and rigid support, considers the impact of the circumferential installation of yielding elements on radial displacement, and proposes displacement approximation and support force approximation methods using displacement coordination and static equilibrium as approximation conditions. The study fits curves of numerical simulation results and laboratory test results of yielding elements, and attempts to directly use the laboratory test data set of yielding elements as computational data.

This study aimed to examine the association between occupational burnout and psychological symptoms among Chinese medical staff, assuming social support to play a moderating role in the aforementioned relationship. The survey was conducted online from May 1 to June 28, 2022, and the questionnaires were distributed and retrieved through a web-based platform. The final sample was comprised of 1461 Chinese medical staff in this cross-sectional study.

Background: The first aim of this study is to test the effectiveness of school-based psychosocial interventions for improving mental health in rural Chinese children with traumatic experiences. The second aim is to examine which individual, family and school related factors could explain the effectiveness of school-based psychosocial interventions. Third, we will investigate whether individual, family, and school related conditions play a moderator role on the effectiveness of school-based psychosocial interventions.

Objective: To date, few studies have examined the relationship among mental health symptom severity, colleagueship, and perceived stigma, especially in Chinese firefighters. This study aims to investigate the association between posttraumatic stress symptoms (PTSS), depressive symptoms, and perceived stigma, taking colleagueship as a moderator.

Method: This cross-sectional study included a total of 1,328 Chinese firefighters.

This study explored pandemic-related social support profiles and investigated their relationships with depressive symptoms among Chinese parents during the COVID-19 pandemic. The hypotheses were evaluated in an online cross-sectional survey of 1286 parents. Latent profile analysis identified two profiles of received social support (isolated and integrated support).

Children are more likely to experience maltreatment and parental conflict in a pandemic context, which can exacerbate their vulnerability to psychological disorders. The purpose of the present study was to examine mental health symptoms in children aged 0 to 10 years and consider related factors from the perspectives of maltreatment and parental conflict during the COVID-19 lockdown. Participants were 1286 parents aged 18 years and over with children aged 0 to 10 years were included.

Background: The COVID-19 pandemic has brought significant changes in society and family life, which could be particularly difficult for parents. The present study examines the relationship between youth mental health and parental psychological distress after the first peak of the COVID-19 Outbreak in China. The parent-child and marital relationships were examined as moderators of the above relationship.

The quality of life (QoL) might have been decreased owing to social disruptions in daily life and basic functioning after the coronavirus disease (COVID-19) pandemic. This work aims to examine the relationship between job changes, family conflicts, and QoL among parents during COVID-19 in China. We recruited 1,209 adults through an online cross-sectional survey in China during the COVID-19 lockdown from April 21 to April 28, 2020.
