Experimental and Numerical Study of Topographic Site Effect on a Hill Near Tehran
This paper compares the experimental study of seismic response of a hill site near Tehran and numerical modeling of the test site using a hybrid finite-boundary element code named HYBRID. Both longitudinal and transversal profiles of the hill have been instrumented using Guralp CMG-6TD seismological stations and some hours of ambient noise were recorded. The H/V ratios for each station were calculated and the amplification patterns and corresponding frequencies of each station have been extracted. Then the two profiles has been modeled numerically and excited by vertically incident SV ricker waves with different fundamental frequencies. The medium is assumed to have a linear elastic constitutive behavior. All calculations are executed in time-domain using direct boundary element method. The amplification patterns, both in time domain and frequency domain, have been determined. The similarities and discrepancies between the experimental and numerical methods have been discussed. It was shown that using microtremor would not be an efficient way for estimating the topographic site effect and may not be applied for microzonation studies of the elevated areas
The relationship between emotional intelligence with general health and safety behavior among workers of a manufacturing industry in 2014-15
Background & Objectives: One of the most important applications of psychological research is problem solving in the safety challenges field. Based on the role of emotional intelligence (EI) in mental health and prevention of unsafe behaviors, and to promote workforce's health, this study aimed to survey relationship between emotional intelligence with general health and safety behavior (BS) in an industry, in 2014. Materials & Methods:In a descriptive-analytical and cross-sectional study, all operational employees working at a publication industry were included. Demographics, Goldberg general health-28, and Bradberry-Greaves questionnaires and a safety behavior checklist were tools to gather data. Statistical analysis of Pearson correlation was used to data evaluation by SPSS V22. Results: Mean EI test score was calculated which was equal to 122.2±15.7. Also, total score of staffs' general health was reported as 50.4±10.4. 646 out 800 of behaviors that were assessed in present study were safe (80.8). There was a significant relationship between EI (self-management component) and general health with correlation coefficient equal to -0.3. Also, depression with correlation coefficient equal to -0.334 was related to EI significantly (P<0.05). Further data revealed that there was significant and severe (0.8) relationship between EI (Social awareness component) with safe behaviors. Also, EI was not in significant relation with safety behavior (P<0.05). Conclusion:The findings of this study collectively indicated that subjects had not an acceptable situation for mental factors such as depression. However the results confirmed an essential role of EI in perceiving general health and preventing employees of negative behaviors. Based on this fact that education can improve EI, design an integrated package for EI development of employees was recommended strongly

Chemical Risk Perception and Safety Behaviors as Key Factors toward Safer Chemical Industries - A Case Study in Iran
Organization and employees’ attitudes towards chemical risks are an important contributing factor for safe and unsafe behaviors. These risks should be controlled to as low as reasonably practicable (ALARP) level. The objective of this study was to assess chemicals risk perception, safety knowledge, attitude and their relationships with safe behavior among chemical workers in Iran. The study was a descriptive-analytical and cross-sectional study. 209 workers from five chemical companies were selected in random and stratified sampling. Vinodkumar questionnaire as a demographic questionnaire and Smith-Jackson questionnaire as a safety behaviour questionnaire was utilized to assess safety knowledge, attitude, and chemicals risk perception. Collected data were analyzed utilizing T, ANOVA, and multiple-linear regression by SPSS V20. Males were in the majority (83.1%). Mean and standard deviation (SD) of age and work experience were 31.75±6.86 and 6.00±5.24 years, respectively. Also, mean and SD of risk perception, safe behavior, knowledge and attitude were 22.33±4.29, 22.12±2.88, 24.79±4.79 and 19.18±3.08, respectively. Gender and education were the most important demographic criteria in the case of difference in four variables. Also, correlation between safety behavior with risk perception and safety attitude was significant (
Studying Psychological and Organizational Factors’ Roles on Occupational Accidents among Nurses and Nursing Aids in Qom, Iran
It is clear that safety in healthcare centres in both fields of staffs and patients is under influence of various factors and needs considering organizational and psychological variables. This study aimed to find the effects of organizational citizenship behaviour (OCB), patient safety climate (PSC) and fatalism on occupational accidents among nurses and nursing aids in one of the non-governmental hospitals in Qom, 2017.
Two hundred people from the study population were selected by simple random sampling method and entered the study. A researcher-made demographics questionnaire, Williamson et al. questionnaire for fatalism and valid questionnaires for PSC and OCB were tools to gather data. The relationship between the variables was analyzed using ANOVA and T-test through SPSS V20 and structural equation was done by AMOS V8.8.
One hundred and seventy-seven questionnaires out of 200 ones were entered into the analysis phase. Women with 104 (58.8%) were the most frequent and 71.8% of participants were married. Participants had an average age of 34.2(±9.37) years. Reliability of the questionnaires was acceptable. Analysis depicted effects of fatalism on occupational accidents (β=0.15), the patient safety climate on OCB (β=0.13), and OCB on occupational accidents (β=-0.13) (
Can Emotional Intelligence be Used as a Tool to Control Occupational Accidents?Case Study in an Iranian Industry
Nowadays, in order to attain safety at workplaces, we must consider two factors: ethical adolescence and emotional intelligence. Emotional intelligence helps people to learn about regulations, experiences and revelation of emotions. This study aimed to survey the relationship between emotional intelligence (EI) with occupational accident in a publication industry, in 2014. In a cross-sectional study, all operational employees (n=98) working at a publication industry were included. Demographics, Bradberry-Greaves questionnaires were tools for gathering data. Occupational accidents were self-reported and then checked against documents in the organization. Statistical analysis such as T-test, ANOVA and Pearson correlation was used for data evaluation by SPSS V20. All workers were men and range of age was reported to be 24-61 with Mean 122.13±15.68. Also, 21.2% of personnel have experienced occupational accidents (0-5 cases). Also, Mean EI test score was calculated to be 122.13±15.68. There was no significant relationship between emotional intelligence scores among workers with and without accidents (p>0.05).Conditions in the view of emotional intelligence were suitable, but continuous improvement for total consideration and circumstances would be vital. Training program preparation free from workers of different educational levels is recommended. The company must provide a program that can afford workers the opportunity to review errors and gain cognitive systems in order to work with the improved conditions
Mental Health Status and its Relationship with Accident and Unsafe Behavior in a Printing and Press Industry, 2014
Physical and psychological health of workers is critical factors in the performance of their works. Also, the number of fatal occupational accidents is high in our country. Based on these facts assessment and control of accidental determinants as well as their relationship with behavior and mental health of workers is vital. This study aimed to survey the relationship between general health, occupational accident, behavioral safety and demographic variables in a printing and publication industry located at a central province of Iran in 2014. In this cross-sectional study, all operational employees (98 persons) were included. Demographic questionnaires, Goldberg general health-28, safety behavior checklist and self-reported accidents were tools used to gather data. Statistical analysis such as independent T-test, ANOVA and Pearson correlation were used and evaluation of data was done using SPSS V20. All workers were men of mean age 41.79±6.77. Studied personnel who had experienced occupational accidents were in the case range of 0-5. Furthermore, 80.75% of the total observed behaviors (800) were safe. Mean score of GHQ test was equal to 50.38±10.39 which was over 23 as the cut-off point. There was no significant relationship between mental health with safe behaviors (p>0.05). In summary workers’ mental health status was unacceptable. Although, conditions of work which was based on the occupational accident and safety behavior have not shown any situation of caution, using ABC model (Activators-Behaviors-Consequences) can help promote personnel behaviors and anticipate accident control
