Abstract
Introduction: A large part of the compensation payments is allocated to the musculoskeletal disorders of the injured employees. The economic losses imposed by these disorders affect not only the individuals, but also the organizations and communities. The aim of this study was to investigate the effect of educational intervention on improving the working conditions of the computer-using employees working in Yazd University of Medical Sciences. Method: This semi-experimental study was conducted among the employees of Yazd University of Medical Sciences. In this regard, 100 computer users were randomly selected and the study was conducted in three stages of investigating the current situation, implementing the educational intervention, and re-investigating the situation. We collected the information one month before and one month after the educational course. For this purpose, we used the Occupational Safety and Health Administration (OSHA) checklist 1910/0900 (31 questions).We analyzed the data using SPSS version 19 and run Chi-square and descriptive statistics to determine the frequency. The significance level was also considered at 0.05. Results: We found that the postures of the participants were unfavorable before the intervention and they were unconscious about it. However, after the intervention, we observed a significant change in their postures (P <0.05). Moreover, we investigated the effect of intervention on desk and workstation medical condition and found no significant difference between the results before and after the intervention (P> 0.05). In other words, we cannot change the inappropriately designed desk or workstation by the training intervention. Conclusion: Interventions based on the ergonomic training had a positive effect on the improvement of participants' posture at work. This improvement one month after the intervention can confirm the sustainable effectiveness of such programs. In addition, educational intervention did not have any effect on the workstations; the training program could not change the workstations that were undesirable in terms of ergonomics.

Abstract
Background: Low-frequency noise as a detrimental occupational and environmental factor which can cause noise annoyance. In addition to noise, factors such as sensitivity and awareness of adverse health effects of noise seem to play an important role in causing annoyance. Therefore, this study aimed to investigate the association of noise annoyance and loudness perception caused by exposure to low-frequency noise with noise sensitivity. Methods: To achieve this goal, 80 students were exposed to low-frequency noise exposure at 65 dBA in an acoustic room. After one hour of exposure, the subjects completed the Weinstein's Noise Sensitivity Scale, Loudness Perception Scale, and Noise Annoyance Scale. Data were analyzed using Mann-Whitney, Kruskal-Wallis test and the Multivariate Analysis of variance (MANOVA). Results: The results showed that the mean score of noise annoyance and loudness perception was significantly higher in the group with high noise sensitivity. Also, increasing the awareness of the harmful effects of noise significantly increased the level of annoyance and loudness perception of individuals. The results of MANOVA showed that noise sensitivity has a significant effect on both the response variables. Also, awareness of the harmful effects of noise only affects loudness perception. The interaction effect of two independent variables was not significant on any of the response variables .Conclusion: In general, it can be concluded that noise sensitivity and awareness of the harmful effects of noise are two important factors that exacerbate the annoyance caused by exposure to low-frequency noise.

Abstract
Background: Noise pollution is considered as a major threat to human society that may affect life quality, efficiency, physical and mental health. Therefore, the present study was aimed to investigate the effects of noise exposure and noise sensitivity on psychological distress in an automobile parts manufacturer's employees. Methods: In this descriptive-analytical study, 325 employees of an automobile parts manufacturer who were exposed to different noise levels in seven groups were investigated. Daily personal noise exposure for each group was measured using calibrated sound level meter (SVANTEK-971) based on ISO-9612 standards. Then employees' mental disorder and noise sensitivity were determined using Kessler Psychological Distress Scale and Weinstein's Noise Sensitivity Scale (WNSS), respectively, and data was analyzed using SPSS v. 23. Results: Mean psychological distress was significantly different between noise sensitivity and noise exposure groups (P-value <0.05). Based on the results of multiple regression analysis among four variables including age, work experience, noise exposure and noise sensitivity, noise exposure and noise sensitivity had significant effect on psychological distress and could explain 0.36 and 0.25 of variance of response variable, respectively. Age and work experience at the level of 5% error had no significant effect on psychological distress status. Conclusion: It can be argued that the worsening of psychological distress in these employees is often due to noise exposure and noise sensitivity. As an individual variable, noise exposure has the greatest effect on increase of psychological distress compared to noise sensitivity level and demographic characteristics studied.

Abstract
Background: Analysis of accident data based on social and economic factors can be useful in determining injury patterns and establishing operational policies to improve safety and health. The purpose of this study is to investigate the effect of socio-economic factors in accidents. Methods: This descriptive-analytical study was conducted based on information obtained from the Labor Inspection Office of Qom Province in 2017. In this study, the required information was extracted from recorded accident forms of 1048 accident cases occurred among victims who were over 18 years old. In this study, the dependent variables include the outcome of accidents divided into two groups of accidents leading to death and injury. Data were analyzed using Stata Software version 23 (Stat Crop. USA). Results: Based on the results, the presence of a safety officer in the industry reduced the risk of accidents leading to injury (AOR = 0.87, 95% CI: 0.72-0.91, P<0.05), people who had received safety training were 0.0009 times less likely to experience accidents leading to injury compared to the other group (AOR = 0.009, 95% CI: 0.0-0.16. P<0.05), and people with undergraduate education were 1.98 times more likely to experience accidents leading to injury (AOR = 0.009, 95% CI: 1.25-2.2. P<0.05). It was further found that people who have experienced the accident beforehand are less likely to have accidents leading to injury than the other group (AOR = 0.05, 95% CI: 0.005-0.72. P<0.05).Conclusions: Therefore, as indicated, many factors have domino effects on different social damages and problems. Accordingly, to lower accidents and modify workforce culture, multi-faceted strategies should be applied properly.

Abstract
Background: One of the major topics related to the very long tunnels is dark hole effect. This is a common phenomenon caused by the sunlight reflected from the surroundings of the tunnel to the eyes of drivers and the lack of sufficient light at the tunnels' entrance, which decreases the contrast of barriers inside the tunnel and also makes it difficult to see potential obstacles at the entrance. The result is an increased risk of traffic accidents in these tunnels. Therefore, the aim of this research is to subjectively assessment the safe rate of lighting in one of the very long tunnels located in the province of Ilam.
Methods: To subject evaluation the safe rate of lighting at the tunnel entrances, two parameters of the average luminance of tunnel entrance and equivalent luminance are required. In this study, Luminancemeter device model S3 was used to measure the average luminance of tunnel entrance. Then, to calculate the equivalent luminance, a YASHICA108 camera with a 35 mm lens was photographed at a distance between the tunnel entrance and a safe stopping point, and then the Holliday polar diagram was used to calculate equivalent luminance (accordance with the standard CIE88-2004).
Results: In this study, the average luminance at tunnel's entrance was equal to 17
, the luminance was equal to 127.5
Using the ADRENAL equation, the quality of lightening at the tunnel entrance was less than 1.
Conclusion: Comparison of the results obtained from the healthy and safety rate of lighting levels at the tunnel's entrance with the De Boer mental scale indicated that a dark hole effect occurs at the entrance of the tunnel under investigation and the light sources installed at the entrance of this tunnel did not have the sufficient ability to inhibit the dark hole effect.
