This may induce chronic increases in blood pressure. The purpose of this study was to determine the presence of hypertension in people working in occupations generally accepted as high stress in comparison to those working in an environment where less of these obvious high stressors were present. Methods: Resting blood pressure was measured by TrUBP in 1067 on-duty first responders (fire, paramedic, and police), and in participants generally associated with a lower-stress work environment (transit workers, city and bank employees, factory workers and legislature employees). Results: The average age, systolic and diastolic blood pressures were significantly lower in those employees working in a high-stress environment than those in a low-stress job. This difference was observed in both male and female sexes. Conclusions: Our data do not support an association of high resting blood pressure values in those employed in activities typically associated with a high-stress urban working environment.展开更多

The disease was first discovered in December 2019 in Wuhan City, Hubei Province, China. A few months later, the disease spread all over the world and became an epidemic. The infection for most people is mild to moderate but in Vulnerable groups, if they have the infections, they might experience severe COVID-19. Saudi Arabia initiated its response plan early, and all sectors and agencies worked in an integrated way to combat the disease. It has maintained proper communication during the pandemic and ensured community involvement, epidemiologic surveillance, and activation of rapid response teams. The COVID-19 pandemic significantly affected daily lives. Schools and daycares were closed, education was online, traveling stopped, work was suspended, gathering in social activities and practicing religious rituals, like praying or doing Umrah or Hajj, were banded. Changing lifestyles as a response to COVID-19 impacted whole communities with different categories of children, parents, and families. Women usually take the majority of daily responsibilities. The sudden change in lifestyle during COVID-19 put pressure on mothers, especially those who are working to balance work and family obligations. This study aims to identify the impact of Coronavirus disease 2019 on working mothers in Saudi Arabia. Method: Data of the study was collected through survey posted on social media and analyzed through Excel. It focuses on five aspects: health, lifestyle, social relations, work production and financial status. Our target population was working mothers in Saudi Arabia aged at least 25 years. Results: In this study, all factors affected working mothers categorized under two groups: Social Economic Status and Work suspension. For Social Economic Status factors, we find five factors which are monthly income, main breadwinner, number of children at school age, type of housing, and type of work. Almost all mothers include spiritual activities to their routine to cope with stress during this period. About half of our sample have negative impact on their mental health because they are the main breadwinner, and mothers with a smaller number of children at school age have more challenges to cope up. We found that mothers who own a house or work at governmental sector have better outcome of health. After analyzing data related to Work suspension, we found that mothers who have work support have better management for life circumstances, however their health outcomes were negatively affected. In addition, mothers working at education sector have the highest positive impact among other sectors. Our data shows that working mothers’ abilities to follow up with their children decreased. This study recommends that there is need to invest more in working mothers’ research and supportive programs and ensure collaboration globally to address working mothers’ needs and share experiences.展开更多

By leveraging the power of MIP solvers, we aimed to minimize the overall digitization time while considering various constraints and process dependencies. The book digitization process involves three key steps: cutting, scanning, and binding. Each step has specific requirements and limitations such as the number of pages that can be processed simultaneously and potential bottlenecks. To address these complexities, we formulate the problem as a one-machine job shop scheduling problem with additional constraints to capture the unique characteristics of book digitization. We conducted a series of experiments to evaluate the performance of our proposed approach. By comparing the optimized schedules with the baseline approach, we demonstrated significant reductions in the overall processing time. In addition, we analyzed the impact of different weighting schemes on the optimization results, highlighting the importance of identifying and prioritizing critical processes. Our findings suggest that MIP-based optimization can be a valuable tool for improving the efficiency of individual work schedules, even in seemingly simple tasks, such as book digitization. By carefully considering specific constraints and objectives, we can save time and leverage resources by carefully considering specific constraints and objectives.展开更多

文摘BACKGROUND Return to work(RTW)and resumption of driving(ROD)are critical factors that influence postoperative quality of life in patients undergoing total hip arthroplasty(THA).However,few studies have focused on the minimally invasive(MIS)approach and its effect on these outcomes.AIM To investigate RTW and ROD's timelines and influencing factors following anterior MIS-THA.METHODS A retrospective analysis was conducted on 124 patients who underwent anterior MIS-THA.Data on the demographics,occupational physical demands,and RTW/ROD timelines were also collected.Clinical outcomes were measured using standardised scoring systems.Statistical analyses were performed to evaluate the differences between the groups based on employment status and physical workload.RESULTS Among employed patients,the RTW rate was 94.7%,with an average return time of five weeks.The average ROD time was 3.5 weeks across all patients.Despite similar postoperative clinical scores,RTW time was significantly influenced by occupations'physical workload,with heavier physical demands associated with delayed RTW.CONCLUSION Anterior MIS-THA facilitates early RTW and ROD,particularly in occupations with lower physical demands.These findings highlight the importance of considering occupational and physical workload in postoperative care planning to optimize recovery outcomes.
文摘Dear Editor,I am writing in response to the article“Assessment of nurses’workplace silence behavior motives:A cross-sectional study”by Alhojairi et al.published in the September 2024 issue of the International Journal of Nursing Sciences[1].This is a letter written by a nurse with 10 years of clinical work experience and a personal interest in team dynamics.I appreciate the authors'recommendations on mitigating workplace silence among nurses to enhance clinical work development,and I believe their proposals could be expanded further.

文摘This paper explored how the work hardening process enhances the yield strength(YS)of magnesium alloy and established a novel quantitative relationship between microstructure and YS.The YS of an extruded Mg–Nd–Zn–Zr alloy was nearly tripled by rotary swaging at 200℃,attributing to dislocation accumulation,grain fragmentation,and basal texture formation.A modified Hall–Petch relationship(GM–HP)was established by introducing the equivalent orientation factor and dislocation density to accurately quantify the YS and the contribution of each strengthening mechanism.The contributions of dislocation hardening and grain boundary strengthening were multiplied by the strong basal texture.This paper offered valuable insights and guidance for designing and optimizing high-strength wrought magnesium alloys and their plastic processing methods.
文摘This paper defines and explores the concept of social reproduction work,highlighting its significance and the fact that women are its primary contributors.It identifies key social issues faced by social reproduction workers,including marginalization,neglect,and unequal access to resources.Additionally,the study examines the primary challenges encountered by these workers:the lack of direct economic benefits,difficulty in balancing work and family responsibilities,and the significant physical and mental strain associated with unpaid labor.Using the theoretical framework of the capitalist economic system,the paper delves into the root causes of the caregiving crisis.Furthermore,it critiques the applicability of reproduction work theories in explaining unpaid care work in the Global South.Three key limitations are outlined:the neglect of informal economic systems in the Global South,persistent gender inequality,and the dynamic nature of global economic migration.

文摘Working memory is a core cognitive function that supports goal-directed behavior and complex thought.We developed a spatial working memory and attention test on paired symbols(SWAPS)which has been proved to be a useful and valid tool for spatial working memory and attention studies in the fields of cognitive psychology,education,and psychiatry.The repeated administration of working memory capacity tests is common in clinical and research settings.Studies suggest that repeated cognitive tests may improve the performance scores also known as retest effects.The systematic investigation of retest effects in SWAPS is critical for interpreting scientific results,but it is still not fully developed.To address this,we recruited 77 college students aged 18–21 years and used SWAPS comprising 72 trials with different memory loads,learning time,and delay span.We repeated the test once a week for five weeks to investigate the retest effects of SWAPS.There were significant retest effects in the first two tests:the accuracy of the SWAPS tests significantly increased,and then stabilized.These findings provide useful information for researchers to appropriately use or interpret the repeated working memory tests.Further experiments are still needed to clarify the factors that mediate the retest effects,and find out the cognitive mechanism that influences the retest effects.
文摘This study focuses on the relationship between job stress and intention to leave among obstetric(OB)nurses in the context of China's birth policy adjustment,and provides a scientific basis for policymakers and healthcare administrators.This study used a non-experimental descriptive correlation design with a purposive sampling of 230 OB nurses from three tertiary hospitals in Jinan,Shandong Province.Participants were surveyed using three questionnaires and descriptive analysis;ANOVA and correlation analyses were used to analyze the relationship between participants'stressor levels and turnover intention.Pearson's correlation coefficient analysis showed that there was a positive correlation between nurses‘work stressors and turnover intention,with a correlation coefficient of r=0.53,a moderate positive correlation(P<0.001).Based on the survey data from three tertiary hospitals in Shandong Province,the obstetric nurses group has a medium level of work stressors,but a high turnover intention,highlighting the professional identity crisis.
文摘quality is a means for auditors to detect material errors when presenting financial reports.In the public sector,audit quality can be seen from the quality of the information contained in information reports published by the government to the public.Examinations carried out by internal inspectorate auditors include reviewing accounting,finance,operations,and others to protect against misstatements which could affect the quality of information displayed by the government through financial reports,performance,and compliance with laws and regulations to the public as transparency efforts to the public.This research aims to empirically test and analyze the influence of auditors’work experience and professionalism on audit quality partially and simultaneously at the Bandung Regency Regional Inspectorate.The population in this study were all auditors who worked at the Bandung Regency Regional Inspectorate with a sample of 35 auditors.The sampling technique used in this research was purposive sampling.A questionnaire was used for the data.This research uses multiple regression analysis,where the results of this research show that partially and simultaneously the variables of work experience and auditor professionalism have a positive and significant effect on audit quality.The implications of the results of this research state that work experience and professionalism are needed to improve audit quality because the results of this research show that work experience and auditor professionalism have a positive and significant effect on audit quality.
