Background: Mental workload (MW) and occupational fatigue (OF) are among the harmful factors in the working environment of the emergency nursing profession, which can be related to the quality of care provided and job stress (JS) in emergency nurses. Accordingly, this study investigates the relationship between MW, MF and JS in emergency nurses in 2023 in Ardabil, Iran. Materials and Methods: This cross-sectional study was conducted by measuring OF, JS and MW of emergency nurses in hospitals of Ardabil Province, Iran. Information was collected through a checklist that recorded the demographic information in addition to the NASA task load index, JS by Orly and Giordano and the Swedish OF inventory questionnaires. The statistical analysis was conducted by the SPSS software, version 22. Results: The mean mental state of the participants was 16.7±3.6. Meanwhile, 40% of nurses had a high mental load. The mean condition of the OF was high (49.02±4.2; 23.2%). Regarding JS, 45.5%, 25.9% and 28.6% were the high, medium, and low levels, respectively. A direct and significant relationship was detected between MW, JS and OF (P<0.05). Conclusion: The mean MW, JS and OF among emergency nurses were high. Almost half and about a quarter of the emergency nurses are under JS and OF, respectively. Therefore, to improve emergency nurses' health conations, and productivity, and create safe conditions in emergencies, the control and management of this harmful occupational factor should be under continuous monitoring.

Background: Driver drowsiness is a significant factor contributing to road accidents and the overall increase in road mortality rates. This study investigates the relationship between number of lane crossing (LC), the amount of lateral position deviations and driver drowsiness. The proposed method, due to precision and convenience, has great potential for developing driver-assistant systems. Materials and Methods: In this experimental research, 34 sub-urban bus drivers participated in a 2-h driving session in a simulator designed based on visual reality. Sensors attached to the steering recorded right and left deviations and relevant information was matched with the receded videos and the amount of the standard deviation of lane position (SDLP). The number of LC was determined with the designed indicator on the road software. Then, the association between SDLP and the number of LC was compared with the results of the Karolinska sleepiness scale (KSS) and observer rating of drowsiness (ORD), which determined the level of drowsiness, by facial features. Results: The results of multivariate analysis of variance indicated that the time variable has a significant effect on both ORD and SDLP (P<0.05). These two variables provided over 99% of the variance. The same results were obtained for KSS and SDLP (P<0.05). Meanwhile, the linear combination of these two dependent variables over 12 periods of the research has significant variations. In addition, the results show the progression of KSS and ORD (P<0.05) and an increase in SDLP and LC (P<0.05). In the same manner, LC has a tight association with the level of drowsiness and other factors (P<0.05). Conclusion: Drowsiness increases the variation in line tracking. However, it is not an appropriate signal for drowsiness detection. The SDLP and the number of line crossings is an. [ABSTRACT FROM AUTHOR]

Background: Road accidents are regarded as one of the most critical global health issues. In Iran, road accidents are the second cause of death, followed by cardiovascular diseases. The present study was conducted with the aim of the epidemiological evaluation of deaths caused by road accidents in Torbat Heydariyeh City, Iran, between 2013 and 2017. Materials and Methods: This is a cross-sectional study in which information on fatal road accidents recorded in the Forensic Medicine Organization of Torbat Heydariyeh City was collected from 2013 to 2017. Excel software was used to analyze the data. A total of 311 fatal accidents have been reported in Torbat Heydariyeh from 2013 to 2017. Results: The Mean±SD age of the deceased was 39.55±22.71. Men accounted for 69% of deaths. Most road accidents occurred in 2016 with a percentage of 24%, most of which happened in the sixth month with a percentage of 13%. Head injury in road accidents was reported as the main cause of death (48%). 130 of the dead were passengers (42%). The type of vehicle used by victims of road accidents was motorcycles (25%), and pedestrians (18%). Conclusion: Since fatal road accidents impose direct and indirect costs on society, intervention measures, such as repairing the roads on accident-prone roads, installing warning signs, defined fines, etc., should be taken to improve public health and prevent the increasing trend of accidents in Iran.

Background: Due to the importance of industrial accidents in workplaces, the current study aimed at epidemiologically investigating occupational accidents in some industrial sites in Semnan, Iran. Materials and Methods: The current descriptive-analytical study was conducted on all accidents taking place from 2014 to 2016 in some industrial sites in Semnan. The data were extracted from the Department of Labor and Social Affairs of Semnan. SPSS software version 21 was employed to analyze data using Chi-square and logistic regression tests. Results: The mean and standard deviation of workers age in non-fatal and fatal accidents were 30.28±13 and 32±11.21 years, respectively. There was no significant difference in variables such as gender, workers experience, marital status, type of industry (construction, mining, rubber, and agriculture), and educational level between fatal and non-fatal accidents (P>0.05). A significant relationship was observed between insurance coverage status and fatal accidents (P=0.002). The rate of fatal accidents was 8.4 times more in 2015 than 2014 (P=0.006; odds ratio=4.8). Conclusion: The rate of accidents in industrial sites can be significantly reduced by taking advantage of accident prevention programs and training courses. Occupational safety and health program can promote the performance of workers. In this regard, the development and conduction of industrial emergency plans can reduce fatal accident rates.

Background: Quality of work life depends on a combination of variables in the work environment that has an important impact on organizational commitment, work participation, and job performance. Therefore, measuring two variables of quality of work life and organizational commitment is important for all employees of organizations, including emergency nurses, who are important members of the health service community. This study aimed to determine the relationship between quality of work life and organizational commitment among Iranian emergency nurses. Materials and Methods: A descriptive and correlational study was conducted in 2016. The study population included all emergency nurses working in one of the hospitals of Kerman Province, Iran. The data collection tool was the personal and occupational questionnaire, Walton quality of work life questionnaire, and Allen and Meier organizational commitment questionnaire. Data analysis was performed by using descriptive tests, the Pearson correlation and ANOVA statistics tests in SPSS V. 23. Results: The results showed that the quality of work life has a positive and significant relationship (r=0.49, P=0.017) with organizational commitment. More specifically, quality of work life is related to emotional commitment (r=0.44, P=0.001), normative commitment (r=0.40, P=0.003) and continuous commitment (r=0.33, P=0.015). Conclusion: Since the higher quality of work life brings more commitment for employees, managers can improve the essential components of working life quality of nurses by adopting appropriate solutions, and providing the necessary conditions for improving the quality of service provision and productivity.

Background: Children's inability to protect themselves, shows the importance of crisis management in preschool period. Preschool administrators can help them with the risk prevention during crisis. We aimed to investigate the professional competencies of preschool administrators based on crisis management approach. Materials and Methods: The study participants included 387 preschool administrators in Tehran, Iran, selected by multi-stage cluster sampling method. The surveying tool was a questionnaire designed based on the Child Care Director Self-Assessment instrument (North Carolina Institute, 2015), which has 76 items covering 11 different competency areas. The obtained data were analyzed in SPSS (Version 21) by performing descriptive tests and inferential statistics like the Kruskal-Wallis test and the stepwise linear regression method. Results: The results showed a significant difference between professional competency of preschool administrators in terms of age, management experience and educational level (P<0.001). Also, regression results revealed that management experience and educational level can predict professional competency for crisis management, but age could not predict the variation in professional competency (P>0.05). Conclusion: Administrators who are more professionally competent in terms of technical, human, and perceptual skills are more qualified for the preschool management, but age variables can not predict eligibility.
