Résumé
Background and aim: Due to the high production rate and the manual nature of the manufacturing of Arc opal dishes the probability of the musculoskeletal disorder onset is high. The aim of present study was to detect and assess the risk of musculoskeletal disorders and its relation to the work pace among the staffs in one of the dishes manufacturing companies.
Materials and Methods: This cross-sectional descriptive-analytical study was carried out on the 100 staffs employed on the decoration section of the company that had job experience equal to one year. They was selected randomly. . To detect the disorders in different parts of the body and to assess the risk of MSDs were used Nordic questionnaireand QEC method respectively. Using SPSS15 software, we analyzed data that used one way ANOVA and Independent Sample t- test.
Results: The results from Nordic questionnaire revealed that the most prevalent disorders in past year related to back [93%], neck[89%], and shoulder[82%] regions respectively. The QEC showed that level of worker exposure with risk factors in back[53%], shoulder[58%], Wrist Hand[71%] and neck[58%] regions is high. Also 71 percent of worker employees have inappropriate posture during work. A significant relation was found between the MSDs and the work pace.
Conclusion: Considering the high prevalence of MSD and analyzing the related risk factors which signifying the risky condition of work environment, it proposed to apply the ergonomic intervention for reduction of work pace.
Résumé
Introduction and Aims: in today's world hazard and related risks are vary and most severity of them are so high that it is practically impossible to compensate for the resulting consequences. Risk assessment is a logical method to evaluate the hazards that discus to detect hazards and their potential impact on people, materials, equipment and the environment. The aim of this study was to identify hazards and assess the risks of different units of the Jahantormoz Company using the Frank - Morgan method
Methods: this Descriptive study was conducted at 12 unit of Jahantormoz manufacture in 2013. In this study, hazards and exist controls was identified by using hazard detection and control checklist then final comparison was conducted by calculating the total investment at risk and the overall risk
Results: according to surveys conducted the highest and lowest hazard scores respectively were obtained from mix [215] and Central warehouse [87] units and highest and lowest control scores respectively were obtained from Perform [234] and Central warehouse [164] units. Also, highest and lowest Risk index respectively were obtained from Cutting unit [88] and central warehouse [-10] units. Finally, Packaging was dedicated highest overall risk index
Conclusion: considering that the packaging unit has the highest overall risk index, this unit has priority in control and required controlling measures should be performed
Résumé
Recent studies in animal models indicate that recombinant human erythropoietin [rhEPO] is very effective in enhancing neurological recovery after spinal cord injury [SCI]. We aimed to evaluate the effect of rhEPO plus methylprednisolone sodium succinate [MPSS] compared to MPSS alone to improve neurological function of patients after SCI in a randomized clinical trial. During a 15-month period 30 patients presenting to emergency departments of two university affiliated hospitals within less than 6 hours after acute SCI were randomized to two groups. Both groups received MPSS 30 mg/kg initially and 5.4 mg/kg every hour till 23 hours if admitted within 3 hours and till 47 hours if recruited within 3-6 hours after injury. Group EPO also received 500unit/kg rhEPO on admission and another 500 unit/kg 24 hours later instead of placebo in group MPSS. Neurologic evaluation was performed on admission, 24, 48, 72 hours and one and 6 months later. Range of patients' age was 18-65 years. There was no significant difference between patients receiving two types of treatment in neurological exam on admission [P=0.125], 24 hours after admission [P=0.108] and 48 hours after admission [P=0.085]. However, one week [P=0.046], one month [P=0.021] and six months [P=0.018] after admission these differences were significant. MPSS plus rhEPO started within 6 hours after acute spinal injury may be more effective than MPSS plus placebo in improvement of neurologic dysfunction. More studies with larger sample sizes are warranted
