There are several methods to evaluate risk factors causing work-related musculoskeletal disorders. this study perform on bakers population of four different types of bakeries(Tafton davar,Tafton sonnati,sangak and baget) and we evaluated WMSDs causal risk factors by OCRA Index technique. Methods: In this research four data gathering methods including observational ,interview ,questioner and check list were utilized. Totally 423 samples by proportional cluster sampling method collected and we used spss15 soft ware for statistical analysis. Results: The results of this investigation demonstrated that maximum mean value of OCRA index in left and right hands were related to shatery task in sangak bakery (OCRA index=14.99).finally,56.5,67.4,77.3 and 75 percent of all tasks at Tafton davar,Tafton sonnati, sangak and baget bakeries respectively were in the red area also our results showed that only ,left and right hands OCRA index means of nandari , forushandegi and nandara/forushandegi tasks were equivalent. Conclusion: with regarding to this point that major of tasks in the bakery job locate in the red zone therefore attention to this problem is necessary and use of ergonomics controls to eliminate or reduce exposure of workers to the ergonomics stressors associated with the development of WMSDs is recommended.

Hookah use has been shown to be associated with various human health problems such as cardiovascular disease, respiratory disease, and cancer. The aim of this review study was to investigate the pollutants in the indoor air of waterpipe cafes. An automated literature search was conducted to identify any relevant studies published up to February 2022. For this search, international digital databases (PubMed, ScienceDirect, and Scopus) were chosen. Multiple keywords were used in the systematic literature review, including "hookah" OR "waterpipe" OR "hubble-bubble" OR "narghile" OR "shisha" AND "café" AND "indoor air." After removing duplicate papers and analyzing titles, abstracts, and full texts, 25 studies remained for analysis and interpretation. Particulate matter, polycyclic aromatic hydrocarbons (PAH), BTEX compounds, carbon monoxide (CO), nicotine, aldehy...

The objectives of the present study was to investigate the effects of safety training on the modification of unsafe behaviors and the role of time on the staff’s behavioral change process in relation to personal protective equipment usage. Method: At the first stage of applying safety behavior sampling techniques, unsafe behavior was evaluated, then a comprehensive safety training course was held according to the desired behavior and sampling process was repeated in three consecutive months. The results were analyzed with repeated measures test and paired t test. Results: Before the training session, 78.29 % of behaviors were unsafe and after the 1st, 2nd and 3rd months of the intervention, unsafe behavior rates reduced to 26.5%, 39.12 % and 67.96%, respectively. The safety training course had significant impact on reducing unsafe behaviors in workers; however its effectiveness is reduced ove...

Therefore, the lack of proper implementation of hygienic protocols in theses environments might increase the risk of getting infected with the COVID-19 among the employees, following the increase of the COVID-19 in the family and community levels. This qualitative study was aimed to explain the challenges of coping with coronavirus crisis in the workplaces.Methods: The present qualitative study was conducted with a conventional content analysis approach. We used the purposeful sampling with maximum diversity in terms of working processes. Data were collected through semi-structured interviews. Interviews were performed to the point of information saturation. MAXQDA software version 10 was used for data management.Results: Through the content analysis of the interviews with the participants, we identified 2 main classes and 9 sub-classes.

Nonetheless, there are some ambiguities regarding various aspects of the mask which are still important to be addressed, including the type of the mask to be used, the situation in which the mask should be used, the correct way to use the mask, and the effectiveness of the mask in preventing the disease. Accordingly, addressing these ambiguities could change policy trends and public beliefs about the use of mask and help control the disease. To this end, this study discusses the role of the mask in preventing and controlling the COVID-19 pandemic.

The knowledge, attitudes, and practice of drivers towards traffic regulations are key factors in decreasing traffic injuries and deaths. The objectives of this research were to study the knowledge, attitudes, and practice of taxi drivers towards traffic regulations in Bandar-Abbas, Iran, and to determine the relationships between demographic features and knowledge, attitudes, and practice of taxi drivers towards traffic regulations. Methods: This cross-sectional study was done in 2014 in Bandar-Abbas, Iran (Hormozgan Province). To study the knowledge, attitudes, and practice of 241 intra-city taxi drivers towards traffic regulations, researchers developed questionnaires and a checklist. The chi-squared test was performed to determine the relationships between knowledge, attitude, and practice of drivers towards traffic regulations and demographic features. Results: Among the 241 drivers, 50 of them (20.7%) thought that the seat belt could cause discomfort while driving, and 107 (44.4%) did not wear a seat belt while driving. The study determined that there was a significant difference between the knowledge and work experience of the drivers (p = 0.014). The 94 drivers (43.5%) in the 31-40 year age group had positive attitudes towards traffic regulations (among 216 drivers expressed positive attitudes) and 92 (44.4%) of the drivers in this age group had safe practices towards traffic regulations (among 207 drivers with safe practice). Conclusion: Many of the taxi drivers in Bandar-Abbas had inadequate knowledge, less positive attitudes, and risky practices towards traffic regulations. Implementation of effective intervention programs may increase the taxi drivers' knowledge, attitudes, and practices towards traffic regulations.

More importantly, asymptomatic carriers could infect healthy people through sneezing, coughing, and talking. Therefore, mask usage is required to prevent and control COVID-19. Objectives: This study was aimed at examining the knowledge, attitude, and performance levels (KAP) of the Iranian population regarding mask usage to prevent and control the COVID-19 outbreak during a one-month period from early April to early May 2020. Methods: A researcher-made, validated, and reliable questionnaire consisting of 30 questions on knowledge, attitude, and performance regarding mask usage was utilized. Data collection was performed through the online method. To do so, the online questionnaire link was provided for the participants via social networks. The correct and wrong answers were scored 1 and 0 points, respectively. The final score of each dimension was calculated and classified as 0 ...

The use of radiation in hospitals and medical centers for diagnostic, therapeutic, and research tasks is inevitable and is developing. So, it is essential to measure, evaluate, and control the amount of dose received by radiologists. Methods:In the first phase of this study, using the checklist to study the results of badge film and how to use individual protective equipment in hospitals surveyed in this investigation and in the second phase, using the Radiometer (05-MKS) TERRA model of the x-ray in different departments of the study hospitals was measured. Results: The maximum dose measured in different departments of hospitals studied by 19 micro Sievert/hour was reported, and in none of the hospitals, the dose has been exceeded. Also, after reviewing the reports of the badge film, it was found that there were no suspicious cases that indicate an excessive receiving dose. The u...
