Abstract
BACKGROUND: Job-related psychosocial factors have a substantial effect on the occurrence of adverse events among healthcare professionals. OBJECTIVE: An analytical and descriptive survey was conducted to evaluate the relationship between the occurrence of patient safety incidents and psychological factors. METHODS: The study sample consisted of 177 nurses who were asked about patient safety events over six months. Repetitive Patient safety incidents were selected by examining medical records and interviewing specialists. Also, psychological factors were assessed using job content questionnaire (JCQ). RESULTS: Repetitive patient safety incidents were involved medication administration error, pressure ulcer and skin-muscular injuries, patient falls, inability to CPR patients, blood transfusion reactions, and death due to human error. The findings showed that 92 participants (52%) had at least one case of patient safety incident. Among patient safety incidents, medication administration error and death due to human error had the highest and lowest repletion, respectively. Nurses training, job insecurity and peer support were significant predictors of different aspects of patient safety (p < 0.05). CONCLUSION: Proper collaboration between new and experienced nurses can have a significant impact to reduce patient safety incidents. In addition, nursing training can be a good way to understand risk points in medical errors.

Abstract
PURPOSE The use of green and eco-natural fibers due to availability, biodegradability, reasonable cost, and non-toxic effects are known as potential acoustic materials in research. Nevertheless, in this area, the use of chemical treatment in natural fibers as an effective strategy to improve the overall properties and acoustic performance is faced with limitations. So that the current paper aims to investigate the effect of alkali treatment on the mechanical and acoustical properties of jute fibers and evaluation of its applicability in noise pollution control. METHODS To determine the effect of alkali treatment on the sound absorption behavior of jute fibers, a sufficient amount of both types of fibers (raw and treated) were used to the fabrication of acoustic samples with thicknesses of 30, 40 and 50 mm at a density of 200 kg/m3. The acoustic evaluation was measured by the Impedance tube system according to transfer function method using by the standard ISO 10534-2. The morphological and tensile properties of fibers were evaluated by the Scanning Electron Microscopy (SEM) and tensile test (ASTM C1557-14 standard). Moreover, Infrared Spectroscopy (FTIR) and X-ray diffraction (XRD) were used to study and compare the chemical properties of raw and treated fibers. RESULTS The result showed that the mean tensile strength and crystallinity index (CI) of treated fibers comparing with raw fibers increased by 61.66% and 3.26% respectively. The use of Alkali treatment helped to improve sound absorption performance of jute fibers with different thicknesses. Furthermore, noise reduction rate (NRC) in treated acoustic samples compared to untreated with a thickness of 50 mm increased from 0.66 to 0.69. CONCLUSION Finally, the alkali treatment has enhanced the properties of jute fibers and confirmed the applicability of these fibers in acoustic absorption.

Abstract
BACKGROUND: Exposure to traffic noise could play an important part in inducing psychological disorders which in turn can affect individuals’ cognitive and mental performance. OBJECTIVE: The aim of this study was to determine the effect of traffic noise exposure on the cognitive performance with regard to subjects’ personality traits. METHODS: Sixty students with normal hearing and vision took part in this experimental study. In order to simulate the traffic noise condition of Tehran, the noise from several busy streets was first carefully recorded. Later on, the subjects were exposed to this recorded noise in an anechoic chamber. Also, the NEO-five factor inventory questionnaire and the continuous performance test were used to assess personality traits and cognitive performance of participants respectively. RESULTS: The results showed that the cognitive features of the study, such as reaction time and the number of commission/omission errors in continuous performance testing increased significantly after exposure to the traffic noise (p < 0.05), and among the personality traits, only the neuroticism has a significant correlation with response time in the continuous performance tests (p < 0.05). CONCLUSIONS: Apart from the effect of traffic noise on cognitive function, the findings of this study confirmed that Neuroticism (one of the personality traits) also significantly affect the cognitive performance of individuals when they are exposed to traffic noise in laboratory conditions.

Abstract
BACKGROUND The objective of this study was to evaluate the acoustical, morphological, mechanical and thermal properties of fibers extracted from the leaves of Yucca (Y. gloriosa) shrub. METHODS Several tests were performed on either untreated or alkali-treated (5% NaOH) fibers. The chemical analysis of the fibers was performed to determine their lignin, cellulose, hemicellulose, wax and moisture content. Fourier transform infrared (FTIR) and thermogravimetric analysis were respectively employed to chemically and thermally analyze the fibers. The microscopic examination was also carried out using scanning electron microscope (SEM). INSTRON universal testing machine and an impedance tube system were employed for measuring the tensile properties of the fibers and the sound absorption coefficient values of the samples fabricated from the same fibers, respectively. RESULTS The results from the experiments revealed that the fibers have low density (1.32 g/cm3) and higher cellulose content (66.36 wt.%,). The mechanical characterization of these fibers also confirmed they are similar to the other lignocellulose fibers used for the reinforcement of polymer matrix composites. The tensile strength test conducted on Yucca fibres showed that mechanical properties of alkali treated fibers are superior to the untreated fibers. The thermal analysis also demonstrated that the alkali treated fibres can thermally withstand temperatures of up to 364 °C which confirms the fact that the thermal stability of fibers was improved by alkali treatment. CONCLUSION Fibers extracted from the leaves of Yucca demonstrated fair amounts of mechanical and thermal resistance and strength. The samples fabricated from Yucca fibers demonstrated fair levels of sound absorption coefficients particularly at higher frequency ranges which are typical to the other natural fibers. The possible use of Yucca fibers as either a reinforcing agent for composites or a sound absorbing medium is highly promising.

Abstract
Background: This study is focused safety and physical health on posture analysis of tools RULA, REBA and QEC were used a cable manufacturing company workers. Methods: The study was conducted on 40 workers engaged in different process of manufacturing. The different activities of the workers were recorded by video and still photography, and these images were used for analysis. Posture analysis tools RULA, REBA and QEC were used. Results: The results of RULA showed that about 30% of the workers were under high risk level and needed a necessary action immediately. About 37.5% of the workers were under medium risk levels and about 25% of the workers were at lower risk levels. The results of REBA have shown that about 27.5% of the workers were under very high risk levels and required immediate change. About 35% of the workers were at high risk levels and a change is necessary soon, and 32.5% of the workers were at medium risk levels. According to the QEC method of assessment, it was found that 7.5 of the workers needed no corrective measures. About 35% of the workers needed additional examination and 32.5% of the workers were at high risk and required immediate change. It can be concluded that there are ergonomic deficiencies in the planning and work approaches. A significant proportion of the workers are working in high risk postures. Therefore, the workers are under moderate to high risk of WMSDs. Conclusions: The current study suggested a suitable implementation of ergonomics interventions program with awareness and training among workers to reduce the risks of WMSD.

Abstract
The present study examines the acoustic behavior sample composites made of date palm natural fibers and polyvinyl alcohol. It also provides the comparison between the sound absorption coefficients obtained from the experimental tests and the ones predicted by the mathematical models. An impedance tube system was used to measure the normal sound absorption coefficient of the samples. Using the differential equation algorithm, the predicted sound absorption coefficient for the Johnson-Champoux-Allard model was also calculated. The sound absorption properties of samples increased significantly by increasing the frequency, and increasing the thickness of materials with constant density. Comparison of the data from the experimental tests and mathematical model showed that increasing the thickness of samples will make the predicted and tested values of acoustic absorption coefficient significantly comparable. Date palm fibers have a good potential for dissipating the energy of sound waves particularly when an air gap is introduced behind the sample and can be used as a new source for the fabrication of natural fiber reinforced composites.

Abstract
There is limited information on the specific psychosocial risks at work that can impact sexual function. The general aim of this study was to investigate the effects of multiple dimensions of psychosocial work stressors on the male sexual function. This was a cross-sectional study conducted among 153 male nurses working in two hospitals in Iran. Sexual function and psychosocial job stressors were measured using the Persian version of the International Index of Erectile Function (P-IIEF) and the Persian version of the Health and Safety Executive (P-HSE) Management Standards Indicator Tool. The Persian version of the Work Ability Index (P-WAI) was used to assess the mediating effect of work ability on the relationship between overall stress and subscales of sexual function. The data were analyzed using Pearson product–moment correlation, one-way analysis of variance (ANOVA), and multiple linear regressions. The subscales of psychosocial job stressors, especially the subscale of role, had a significant correlation with several domains of sexual function. The regression modeling indicated that the subscales of role and job demands were significant predictors of various domains of sexual function. The effect of overall stress on intercourse satisfaction was fully mediated by WAI. In the other indicators of sexual function, overall stress score had only a significant direct effect, not mediated by WAI. Intervention programs to improve sexual function should focus on increasing nurses’ involvement in making decisions related to jobs and on using ergonomic principles related to balancing job demands and the level of nurses’ capabilities.

Abstract
The aim of this study was to measure BTEX (benzene, toluene, ethylbenzene, and xylenes) concentrations in the ambient air of Tehran, the capital of Iran, and investigate their seasonal variations, probable sources, spatial mapping, and risk assessment. The concentrations of BTEX were measured using a continuous monitoring device installed in seven stations around the city. Spatial mapping procedure was conducted using the inverse distance weighting (IDW) method. Monte Carlo simulation was used to assess the carcinogenic and noncarcinogenic risks imposed by BTEX. The highest and lowest annual mean concentrations of toluene and ethylbenzene were recorded as 16.25 and 3.63 μg m(-3), respectively. The maximum (6.434) and minimum (3.209) toluene/benzene (T/B) ratio was observed in summer and winter, respectively. The spatial distribution of BTEX pollution indicated that the highest concentrations were found along the major roads because of heavy traffic. Spearman's rank correlation coefficients and concentration ratios showed that BTEX were produced by the multiemission sources. The mean of inhalation lifetime cancer risk (LTCR) for benzene was 3.93 × 10(-7), which is lower than the limits recommended by the United States Environmental Protection Agency (US EPA) and the World Health Organization (WHO). The hazard quotient (HQ), noncarcinogenic risk index, for all BTEX compounds was <1. The obtained results showed no threat of BTEX concentrations to human health. However, as the concentrations of BTEX will increase due to the rapid growth of vehicles and industrial activities, much effort is required to control and manage the levels of these compounds in the future.
