Abstract
Introduction: Musculoskeletal disorders are one of the most common causes of occupational injuries and disability in industrialized and developing countries. The purpose of this study was to investigate the prevalence rate of musculoskeletal disorders (MSDs) and to conduct posture assessment among workers of Yazd Electrode Company.
Methods:This cross-sectional study was conducted among 59 production line workers of Yazd Electrode Company in 2014. The prevalence rate of MSDs was assessed by Nordic musculoskeletal questionnaire (NMQ). The workers' posture status was also assessed through quick exposure check (QEC). Data were then analyzed by SPSS 22.
Results:According to NMQ results, 86.4 % of participants experienced MSDs at least in one of their nine body regions during the last year. The highest prevalence rates of MSDs were observed in lower back (74.6%), neck (71.2%), and shoulder (59.3%), respectively. The results of body posture assessment through QEC method also indicated that in 59.3% of cases, the risk level of disorders is very high.
Conclusion:The results of this study showed that the prevalence rate of MSDs among workers was high. The main ergonomic problems included having awkward posture, lifting and manual handling of loads, as well as bending and twisting of lower back. Moreover, the findings further indicated that the QEC method can provide reliable results to determine the risk of musculoskeletal disorders.

Abstract
Introduction: One of the worrying and increasing environmental problems is urban and industrial waste water pollution, such as chromium (Cr). Given the destructive effects of Cr and non-degradability, its removal is of great importance. Adsorption method by low-cost biosorbents has been a successful method in during the last decade. This study aims to examine the effect of usual and acid-modified fig leaves powder as a biosorbent for removing of Cr (VI) from a synthetic aqueous solution.
Methods: Laboratory tests were designed and implemented, including solution making of Cr (VI) and then in order to study the effect of different parameters, including solution pH, contact time, solution concentration, and adsorbent dosage, the secondary amount of chromium concentration was measured and compared by atomic absorption spectrometer.
Results: The results showed that for usual adsorbent, optimum parameters included pH 2, 200mg/l initial concentration, 40g adsorbent concentration, and 120min equilibrium time while for the modified adsorbent, optimum parameters were pH 3, 300mg/l initial concentration, 40g adsorbent concentration, and 120min equilibrium time. The maximum adsorption percentage of Cr (VI) in the first case was 54.33% and in the second case was 91.50%. In addition, by examining adsorption isotherms and kinetic models, it was found that Cr adsorption in both cases follows Langmuir isotherm (R2=0.942 for usual and R2=0.975 for modified adsorbent) and pseudo-second order kinetic model (R2=0.976 for usual and R2=0.982 for modified adsorbent).
Conclusion: More efficient removal of Cr using a modified adsorbent compared to usual adsorbent and previous studies indicates the suitability of modified fig leaves powder as an adsorbent of Cr (VI).

Abstract
Introduction:Patient safety is a fundamental principle in healthcare. Patient's safety-friendly standards are a set of requirements which are critical to the implementation of a hospital-wide patient safety program. This study aims to investigate patient's safety in Ahvaz Abuzar Hospital based on patient's safety-friendly standards.
Method: This was a cross-sectional descriptive study conducted in 1401 on 30 employees related to patient safety through a non-random and purposive sampling method. The required data were collected by the first two axes of the World Health Organization's patient safety-friendly standards checklist, including governance and leadership - participation and interaction with patient and society, and using observation, interview and hospital documentation techniques. Data were analyzed using statistical tests (mean and standard deviation) of SPSS26 software and scored on a three-point Likert scale.
Results: The level of the hospital's compliance with the first two axes of patient's safety-friendly standards (64 standards in total) was considered good with an average of 80/4%. Mandatory and basic standards were at a good level and advanced standards were at an average level. The group of attracting participation and interacting with the patient and society with an average of 82/7% showed more compliance than the governance and leadership group with an average of 78/09%.
Conclusion: The condition of Abuzar Hospital was considered to be at a good level in terms of compliance with patient's safety-friendly standards. It is better to focus on the level of compliance with basic and advanced standards in future studies.
