The bars were carefully extracted from the beams and tested in order to evaluate residual tensile properties. The results show that the tensile strength decreased significantly in the highly aggressive conditions but not in the natural conditions. The effect of GFRP bars casting in concrete beams demonstrated approximately 2.5% decrease of tensile strength caused by pore water environment in concrete beams on basis of those of the original bars. The effect of sustained loading plus work cracks demonstrated about 10.5% tensile strength decrease on basis of those of the bars only casted in concrete beams. The effect of environments under sustained loading plus work cracks demonstrated about 17% tensile strength decrease caused by a saturated solution of Ca(OH)2 and 60-2 ℃ tap water (pH=12-13) and about 8% tensile strength decrease caused by freezing and thawing cycle (F/T), both on basis of those of the bars of the indoor beams only under sustained loading plus work cracks. The results demonstrate the effects of the tensile strengths under different environmental conditions of GFRP bars in concrete beams with work cracks subjected to sustained loads.展开更多

Aim: The purpose of this pilot study was to explore how consultant doctors (CDs) experience their competence as utilized in practice and what impact this has on their perceived psychosocial work environment. Methods: The findings are based on 11 interviews with CDs working on consultancy assignments in Norway. The CDs were all specialists in fields such as general practice, psychiatry, anesthesia, gynecology, orthopedics, and otolaryngology. Results: The competence that the CDs contributed to their hosting work organization was interpreted differently based on whether the consultant played an active role in the psychosocial work environment and also depended on the doctor’s specialty. Not being integrated into the hosting work organization enhanced the feeling of exclusion and the idea that little or no room was available to contribute one’s competence. Most of the CDs experienced their competence as being utilized to a certain extent, which strengthened their work satisfaction and feeling of playing an active role in the psychosocial work environment.展开更多

Nurses are expected to deliver humane, empathetic, culturally-sensitive and proficient care in working environments with limited resources and increasing responsibilities. Such imbalance between providing high quality care with limited resources leads to physical and mental stress. This stressful nature of nursing can ultimately lead to job dissatisfaction and burnout which among health care providers are important issues since they affect turnover rates, staff retention and ultimately the quality of patient care. A thoroughly validated self developed questionnaire with a reliability coefficient of 0.78 was used to explore the effect of work environment on the level of work stress and burnout among nurses. A purposive sampling technique was utilized to select 100 participants from the medical unit of the hospital. Three hypotheses were tested at a significant level of 0.05. Data were analyzed using ANOVA and Pearson’s Correlation. The study revealed that level of stress was higher among the staff nurses who had worked for only between 0 and 3 years, with mean stress score 46.0000. Findings further revealed that as the cadre rose, the nurses assumed that managerial roles were accountable for increased subordinates and oversee health related and administrative responsibilities and they experienced more stress. Also there is a significant relationship among work environment, stress and burnout among the nurses in the selected unit. In conclusion, though work conditions and environment are not favourable, there are job security and good interpersonal relationship among the nurses which cushion the stressful situations. It is therefore recommended that the management of the hospitals should provide a conducive work environment, providing necessary resources and adequate break periods to ensure staff welfare.展开更多

Is it an indicator of the workplace satisfaction level, according to the perception of Hitachi Chemical employees in Montemorelos, Nuevo León, México? This study's design is both explanatory and cross-sectional. The sample size was composed of 143 Hitachi Chemical employees of Montemorelos, Nuevo León, México. For the data collection, two instruments were used: the first instrument was used to measure the quality of organizational climate and the second was focused on measuring the workplace satisfaction level. As a result, the level of organizational climate quality is in fact a predictor of workplace satisfaction of Hitachi Chemical employees. After the regression analysis, it was found that the variable, level of organizational climate, explained a 71.4% variance in the dependent variable, work satisfaction. It was determined that organizational climate is a strong predictor of work satisfaction perceived by employees of Hitachi Chemicals, Montemorelos, Nuevo León, México. It can be established that the greater the levels of organizational climate experienced by the employees, the greater the level of work satisfaction will be.展开更多

However, members of these teams often work in stressful and unhealthy environments, which can undermine their productivity and well-being. The humanization of the culture of technology teams is an approach that aims to create healthier and more productive work environments for team members, promoting balance between personal and professional life. Despite the importance of a healthy and productive work environment, many companies do not invest in strategies to humanize the culture of their technology teams. This can lead to high levels of stress, staff turnover and low productivity. The objective of this project is to identify effective strategies to humanize the culture of technology teams and create healthier and more productive work environments in digital companies. For this, factors such as management styles, psychological safety, human-centered development, individual beliefs and time and energy management will be analyzed. The project’s methodology will include a literature review on the subject and qualitative data analysis will be performed using a content analysis approach. This project will contribute to the advancement of knowledge about the humanization of the culture of technology teams in digital companies. The results can be applied to companies that want to create healthier and more productive work environments for their team members.展开更多

Although the earliest studies on stress were mostly physiological, psychological models of stress have been developed and established a link between stressors and illness in his model of general adaptation syndrome.<strong> Objective:</strong> To investigate prevalence and factors associated with occupational stress among nurses working Asser region Hospital. The study included nurses at different age groups working at different departments with assessment of any sources of stress. <strong>Methodology: </strong>A descriptive cross-sectional study was conducted targeting nurses in the main hospitals in the Asser region, Southern Saudi Arabia. A total of the study samples of 217 nurses were required to estimate the expected average stress rate among nurses. A self-administered pre-structured questionnaire used for data collection. <strong>Results: </strong>Nurses’ ages ranged 21 to 55 years old with mean age of 30.9 ± 11.7 years old. Majority of the nurses were females 175 (80.6%). The highest mean score (more stress) was reported by nurses in relation to the following stress factors;working very hard (4.3 ± 0.9), followed by being under pressure to work long hours (4.2 ± 0.9), the opportunity given to do something is not real and enough (4.2 ± 1.0). The findings showed a significant relationship between nurses’ stress level, their personal and work-related characteristics (P = 0.001). <strong>Recommendations:</strong> Interventional programs to detect and alleviate sources and effects of occupational stress should be developed including more training regarding coping strategies, nurses’ support, and better work condition.展开更多

Externalizing disorders of childhood including Attention Deficit Hyperactivity Disorder, Conduct and Oppositional Disorders are a prominent feature of those with a positive family history. The caudate nuclei have been implicated in both the salience of rewards and in the pathophysiology of alcohol dependence and these often antecedent childhood disorders. Methods: Adolescent/young adult high and low-risk for AD offspring (N = 130) were studied using magnetic resonance imaging. Volumes of the caudate nucleus were obtained using manual tracing with BRAINS2 software and neuropsychological functioning determined. Childhood disorders were assessed as part of a long-term longitudinal follow-up that includes young adult assessment. Dopaminergic variation was assessed using genotypic variation in the catechol-O-methyltransferase (COMT) and DRD2 genes. Results: High-risk subjects showed poorer Working Memory functioning. Caudate volume did not differ between high and low-risk subjects, but those with externalizing disorders of childhood showed reduced caudate volume. Variation in COMT and DRD2 genes was associated with Working Memory performance and caudate volume. Conclusions: Caudate volume is reduced in association with externalizing disorders of childhood/adolescence. Working Memory deficits appear in familial high-risk offspring and those with externalizing disorders of childhood. The dopaminergic system appears to be involved in both working memory performance and externalizing disorders of childhood.展开更多

文摘Nurses’ roles expose them to a lot of stress based upon the physical labour, exposure to human suffering, lengthy work hours, poor staffing, and interpersonal relationships that are central to the work they do. Nurses are expected to deliver humane, empathetic, culturally-sensitive and proficient care in working environments with limited resources and increasing responsibilities. Such imbalance between providing high quality care with limited resources leads to physical and mental stress. This stressful nature of nursing can ultimately lead to job dissatisfaction and burnout which among health care providers are important issues since they affect turnover rates, staff retention and ultimately the quality of patient care. A thoroughly validated self developed questionnaire with a reliability coefficient of 0.78 was used to explore the effect of work environment on the level of work stress and burnout among nurses. A purposive sampling technique was utilized to select 100 participants from the medical unit of the hospital. Three hypotheses were tested at a significant level of 0.05. Data were analyzed using ANOVA and Pearson’s Correlation. The study revealed that level of stress was higher among the staff nurses who had worked for only between 0 and 3 years, with mean stress score 46.0000. Findings further revealed that as the cadre rose, the nurses assumed that managerial roles were accountable for increased subordinates and oversee health related and administrative responsibilities and they experienced more stress. Also there is a significant relationship among work environment, stress and burnout among the nurses in the selected unit. In conclusion, though work conditions and environment are not favourable, there are job security and good interpersonal relationship among the nurses which cushion the stressful situations. It is therefore recommended that the management of the hospitals should provide a conducive work environment, providing necessary resources and adequate break periods to ensure staff welfare.

文摘Objective:The objective is to assess the direct and indirect effects of nurses’organizational commitment(OC)on their work environment perceptions(WEP)and the role of the psychological contr act(PC).Methods:A cross‑sectional quantitative study of 3047 registered nurses in four Chinese hospitals was conducted.The Essentials of Magnetism II(Chinese version),OC,and PC scales were used in the study,and the structural equation modeling was used to assess the connections among variables.Results:The results showed that OC was positively correlated with WEP(r=0.561,P<0.001),and PC was negatively correlated with the WEP(r=−0.717,P<0.001),and OC(r=−0.739,P<0.001).Nurses’PC played a strong mediating role between OC and WEP,accounting for 87.64%of the total effect.Besides,PC played an important role in creating a healthy work environment.Conclusions:The exploration of the relationships among WEP,PC,and OC provides new insights for hospital managers to build a better work environment for nurses,which is conducive to maintaining a stable nurse team and providing high‑quality nursing services for patients.
文摘Mathematical model is developed for prediction of physiological changes in man during work in hot environment taking into consideration intensity of work, clothing and environment. To evaluate human functional state the heat stress index was calculated. Modeling researches made the conclusion that the main risk factor during work in hot environment is water losses that happens through thermoregulatory sweat evaporation. Modeling showed that in humid environment man wearing protective clothing has short time to work as water losses became more than 2% of human weight that means body dehydration. Preliminary model prediction can be used as preventive method to avoid hazard of human health.

It was determined that organizational climate is a strong predictor of work satisfaction perceived by employees of Hitachi Chemicals, Montemorelos, Nuevo León, México. It can be established that the greater the levels of organizational climate experienced by the employees, the greater the level of work satisfaction will be.
文摘With the advancement of technology, companies are increasingly dependent on technology teams to stay competitive. However, members of these teams often work in stressful and unhealthy environments, which can undermine their productivity and well-being. The humanization of the culture of technology teams is an approach that aims to create healthier and more productive work environments for team members, promoting balance between personal and professional life. Despite the importance of a healthy and productive work environment, many companies do not invest in strategies to humanize the culture of their technology teams. This can lead to high levels of stress, staff turnover and low productivity. The objective of this project is to identify effective strategies to humanize the culture of technology teams and create healthier and more productive work environments in digital companies. For this, factors such as management styles, psychological safety, human-centered development, individual beliefs and time and energy management will be analyzed. The project’s methodology will include a literature review on the subject and qualitative data analysis will be performed using a content analysis approach. This project will contribute to the advancement of knowledge about the humanization of the culture of technology teams in digital companies. The results can be applied to companies that want to create healthier and more productive work environments for their team members.

文摘<strong>Background:</strong> Over the last century, stress as an interdisciplinary concept has become an area of great interest and has been researched extensively. Although the earliest studies on stress were mostly physiological, psychological models of stress have been developed and established a link between stressors and illness in his model of general adaptation syndrome.<strong> Objective:</strong> To investigate prevalence and factors associated with occupational stress among nurses working Asser region Hospital. The study included nurses at different age groups working at different departments with assessment of any sources of stress. <strong>Methodology: </strong>A descriptive cross-sectional study was conducted targeting nurses in the main hospitals in the Asser region, Southern Saudi Arabia. A total of the study samples of 217 nurses were required to estimate the expected average stress rate among nurses. A self-administered pre-structured questionnaire used for data collection. <strong>Results: </strong>Nurses’ ages ranged 21 to 55 years old with mean age of 30.9 ± 11.7 years old. Majority of the nurses were females 175 (80.6%). The highest mean score (more stress) was reported by nurses in relation to the following stress factors;working very hard (4.3 ± 0.9), followed by being under pressure to work long hours (4.2 ± 0.9), the opportunity given to do something is not real and enough (4.2 ± 1.0). The findings showed a significant relationship between nurses’ stress level, their personal and work-related characteristics (P = 0.001). <strong>Recommendations:</strong> Interventional programs to detect and alleviate sources and effects of occupational stress should be developed including more training regarding coping strategies, nurses’ support, and better work condition.
文摘Objective:To examine the effects of various hazardous factors in working environments on burnout in a cohort of clinical nurses in Macao.Methods:A cross-sectional survey was used to examine specific workplace hazards for burnout in qualified nurses(n=424)in Macao.Structural equation modeling(SEM)was used to analyze relationships between specific hazards and manifestations of burnout.Results:In the final model,workplace hazards accounted for 73%of the variance of burnout with a standardized regression weight of 0.85.The measures of the model fit were acceptable.Bodily hazards,threats of violence,and physical environmental hazards were found to significantly contribute to two major determinants of burnout,emotional exhaustion and depersonalization.Conclusions:Workplace environmental hazards increased the risk of burnout amongst clinical nurses in Macao.Better management of these factors may help to protect nursing staff and reduce the risk of burnout and attrition from the nursing profession.
文摘Background: There is emerging evidence that the increased susceptibility to developing alcohol and substance use dis- orders in those with a family history of Alcohol Dependence (AD) may be related to structural differences in brain circuits that influence the salience of rewards or modify the efficiency of information processing. Externalizing disorders of childhood including Attention Deficit Hyperactivity Disorder, Conduct and Oppositional Disorders are a prominent feature of those with a positive family history. The caudate nuclei have been implicated in both the salience of rewards and in the pathophysiology of alcohol dependence and these often antecedent childhood disorders. Methods: Adolescent/young adult high and low-risk for AD offspring (N = 130) were studied using magnetic resonance imaging. Volumes of the caudate nucleus were obtained using manual tracing with BRAINS2 software and neuropsychological functioning determined. Childhood disorders were assessed as part of a long-term longitudinal follow-up that includes young adult assessment. Dopaminergic variation was assessed using genotypic variation in the catechol-O-methyltransferase (COMT) and DRD2 genes. Results: High-risk subjects showed poorer Working Memory functioning. Caudate volume did not differ between high and low-risk subjects, but those with externalizing disorders of childhood showed reduced caudate volume. Variation in COMT and DRD2 genes was associated with Working Memory performance and caudate volume. Conclusions: Caudate volume is reduced in association with externalizing disorders of childhood/adolescence. Working Memory deficits appear in familial high-risk offspring and those with externalizing disorders of childhood. The dopaminergic system appears to be involved in both working memory performance and externalizing disorders of childhood.
