The Occupational burnout is considered as one of the most important problems that have numerous adverse effects on nurse's job. Various personal, psychological and social factors are effective in occupational burnout. Therefore, the goal of this study was to find out the relationship between emotional intelligence and job stress with occupational burnout of nurses working in public hospitals of Kerman. This descriptive-analytical and cross-sectional study, was conducted on 300 nurses working in Kerman hospitals who selected randomly by stratified method. Organizational and demographic questionnaire and occupational burnout, emotional intelligence and job stress questionnaires have used. Structural and confirmatory factor analysis models were used to measure the model of the study. Emotional intelligence and job stress affect occupational burnout. In addition, there were meaningful and negative relationships between emotional intelligence and job stress (P

Noise-induced hearing loss is considered as one of the most common occupational problems. Audiometric pattern of NIHL is different in various workplaces.
This study was designed to find the prevalence and pattern of hearing loss in tile and ceramic industry.
This was a cross-sectional study on 853 tile and ceramic workers in Yazd. Plants were selected by simple random sampling from all tile and ceramic plants in Yazd. Hearing thresholds were recorded at 500, 1000, 2000, 3000, 4000, 6000, and 8000Hz. Hearing loss at each frequency was defined as hearing threshold higher than15 dB-HL. Data were analyzed by SPSS (ver. 20) using Student’s

Being threatened by various facilities in a city, modern urban environments have become extremely vulnerable and fragile. Hospitals are among potentially high-risk facilities. Environmental awareness is relatively lacking in the health sector with few organizations measuring their performance. Therefore, the issue is exceedingly important. This paper aims to identify and prioritize factors that influence environmental performance in hospitals. To identifying factors that influence environmental performance in hospitals, a comprehensive review of literature was performed to compile a list of criteria, sub-criteria, and indicators of environmental performance in healthcare centers. The list was then adjusted by experts in the field using the fuzzy Delphi method and the factor were prioritized using fuzzy analytical hierarchy process. In order to verify the results, fuzzy technique for order of preference by similarity to ideal solution was also applied. Therefore to verify the weights and priorities assigned to the factors influencing environmental performance, the factors were once again rated by experts based on the criteria of specificity, measurability, availability, being realistic, and time-related. According to obtained results, 6 criteria, 22 sub-criteria, and 48 indicators were identified and prioritized. Furthermore, Fuzzy AHP and Fuzzy TOPSIS resulted in the same prioritization of the factors. Therefore, the results obtained from Fuzzy AHP are acceptable. Using appropriate indicators together with appropriate techniques can serve to improve environmental performance in health care centers and the obtained results showed that the FAHP method can be used for prioritizing environmental performance factors in hospitals successfully.

It is well established that unstable footwear with a rounded sole design have the potential to alter lower limb muscle activity during standing and walking activities. Thus, the main objective of this study was to compare lower leg muscles fatigue rates between stable and also unstable footwear during prolonged standing. Ten young healthy man were participated in this study. During 2 h of continuous standing with two footwear conditions (stable and unstable shoes), surface electromyography (EMG) data of bilateral tibialis anterior (TA) and medial gastrocnemius (MG) muscles were continuously collected. The probability of muscle fatigue was identified through recording simultaneous increase in the EMG amplitude and shift in the EMG frequency spectrum towards lower frequencies. Analysis of EMG recordings revealed that standing with stable shoe significantly yielded higher rates of muscle fatigue for bilateral MG muscles. Furthermore, no significant differences were observed for the fatigue rates of TA muscles between two footwear conditions. However, none of monitored muscles were indicated fatigue during standing with unstable shoe. The results suggested that unstable footwear, compared to stable one, more efficient to prevent the occurrence of muscle fatigue which seemed to be advantageous for the musculoskeletal system. Therefore, unstable footwear can be recruited as ergonomic intervention for individuals whose stand for prolonged periods.

The aim of this study was to compare the effect of change phase paraffin cooling vest and Iranian Spadana gel ice cooling vest on the perceptual strain score index (PeSI) and physiological strain score index (PSI). This study investigated the effect of the vests on the wearers’ ability to work in hot and humid working conditions of Assaluyeh in Iran. The importance of preventing heat stress and maintaining individuals’ performances in hot workplaces provided the impetus for this study.
This cross-sectional interventional study was conducted in 2016 on 90 individuals (30 individuals with Iranian cooling vests containing Spadana cooling gel ice packs, 30 individuals with change phase paraffin cooling vests, and 30 individuals without vests). All 90 were workers with an identical level of physical activity and uniforms in Assaluyeh , which has an average temperature of with 47°C and 95% relative humidity in the summer. The heart rate (HR) and oral temperature (OT) were measured in order to assess the (PSI), and the questionnaires of PeSI and heat strain score index (HSSI) were also administered to assess the PeSI and the sweating while wearing the vests and in the control group, The WBGT index was measured for 120 minutes as well, and the checklist of individual strength (CIS) and the comfort assessment questionnaire were filled by the workers too. The repeated measures Test and the statistical analysis software SPSS 21 were used to analyse and compare the data.
The WBGT mean index was 37.65°C for all the three groups, the average heart rate in the group with the Iranian cooling vests was 91.76, in the group with the paraffin cooling vests was 89.53, and in the control group was 97.07 beats per minute. The mean oral temperature in the group with the Iranian cooling vests was 36.7°C, in the group with the paraffin cooling vests was 36.78°C, and in the control group was 36.63°C. The mean of PSI value was 3.18 in the group with the Iranian cooling vests, 2.29 in the group with the paraffin cooling vests, and 6.12 in the control group. The mean PeSI value in the group with Iranian cooling vests containing Spadana cooling gel ice packs was 7.39, while HSSI value was 6.33. For the group with paraffin change phase vests, the mean PeSI value was 6.36, while the HSSi value was 5.92. For the control group, the PeSI value was 9.95 and the HSSI was 13.28. The mean scores of PeSI, HSSI, PSI, and CIS in the groups with paraffin change phase cooling vests and Iranian cooling vests containing Spadana cooling gel ice packs had a statistically significant difference compared to the control group (P0/05).
The findings suggest that wearing the paraffin cooling vests and the Iranian cooling vests with Spadana gel ice for 90 minutes can acceptably and appropriately reduce the heat stress level of the users by decreasing the oral temperature, the heart rate, and the PeSI value, while increasing the CIS score.

vibration can disrupt comfort, decrease effective labor and adversely affect peoples’ health and safety. This study aimed to evaluate vibration and its relationship with lower-back pain in drivers of heavy vehicles in the mines of Sirjan Gol-e-Gohar Complex.
this cross-sectional study was conducted on drivers of heavy vehicles in mines of Sirjan Gol-e-Gohar Complex in 2013. The statistical population consisted of 432 (216 cases and 216 controls) people. Data was collected using Nordic questionnaire. Data was analyzed using SPSS20 software and statistical tests including T-test, ANOVA, chi-square and logistic regression test. Moreover, P The prevalence of musculoskeletal disorders was significantly different in all three study aspects: in the past 12 months, in the past 12 months which resulted in limited activities and in the past 7 days in waist and back of drivers and non-drivers (P vibration is a major factor causing musculoskeletal disorders in the back. Therefore, some suitable preventive measures must be taken to reduce exposure to vibration and to control it.
