    The main objective of this study was to develop a fuzzy–based framework for the prioritization of health, safety and environment related risks posed against employees, working conditions, and process equipment in large gas refineries. The First Refinery at Pars Special Economic Energy Zone in South of Iran was taken as a case study. For this purpose, health, safety and environment related risks were determined based on the three criteria of impact severity, occurrence probability, and detect-ability using a questionnaire of 33 identified failures. The values obtained were processed by a so-called ‘contribution coefficient’. The results were then subjected to fuzzification and fuzzy rules were defined to calculate the risk level indices as the model outputs, which was then employed to facilitate the management decision-making process by prioritizing the management options. The prioritization values were then classified in six categories in the order of risk severity. Results revealed that failure in a combustion furnace had the highest rank while failure in the slug catcher ranked the lowest among the risk sources. It was also found that about 0.4% of the identified risks prioritized as “intolerable”, 79% as “major”, 20% as “tolerable”, and 0.7% as “minor”. Thus, most of the risks (more than 79%) associated with the refinery has the potential of significant risks. The results indicated that the risk of the pollutant emissions from the combustion furnaces is the highest. Exposures to harmful physical, chemical, psychological, and ergonomic substances are the other risks, respectively.

    Fire is a physical and social phenomenon that affects both individuals and the environment. Fire risk assessment is a critical part of a fire prevention program. In this process, the fire risk associated with the possibility of occurrence and severity of damage resulting from the fire is estimated and calculated. In this paper, a classification scheme and a systematic literature review are presented in order to classify and interpret the current researches on fire risk assessment methodologies and applications. Based on the scheme, 93 scholarly papers from 13 journals are categorized into application areas and other categories. The application areas include the papers on the topics of environmental impact, production and industry, transportation, buildings, power industry, oil and gas industry, urban fires and other topics. Scholarly papers are also classified by (1) year of publication, (2) journal of publication, (3) year of publication and application areas and (4) authors’ nationality. The survey results show that the largest number of papers was published during the period 2010-2012 with 31 (33.33%), the most of the studies have been carried out on environmental impact (47.31%), the journal of Forest Ecology and Management had the highest percentage of articles with 26.88%. It is hoped that the paper can meet the needs of researchers for easy references of fire risk assessment methodologies and applications. Therefore, this work would be able to provide useful insights into the anatomy of the fire-risk assessment methods, and suggest academic researchers and experts a framework for future attempts and researches.

    Physicochemical quality of water from the acceptability point of view is essential for consumers; protecting the health of consumers and maintenance of water supply systems. The aim of this study is to determine temporal and spatial variations of Calcium and Magnesium in Ilam drinking water sources using the GIS system.
    This cross-sectional study was conducted on 20 drinking water sources in Ilam city and the 5 years results by water and wastewater company archive GIS software version 3.9 were analyzed via SPSS version 16 as well as one-way variance analysis. Water and wastewater sampling and measurement were conducted in order to verify the data by researchers according to standard methods.
    Based on interpolation map, the maximum calcium and magnesium contents are related to western and central regions. ANOVA test showed that there no a significant difference between the mean calcium variable verification test in summer during 2009-2013 and at 95% level. (P=0.760>0.05). The one-way analysis of variance showed that there is a significant difference between the average magnesium variable in summer during 2013-2009 years and the verification test at 95% level. (P=0.019

    In day-to-day life concrete become a compulsory material in the construction field as to make it a real concern among researchers for producing concrete with improved properties. Biological method is one of the new methods to improve concrete properties. Although, much research about biological concrete has been carried out, but till now nobody has not studied for the psychological effects of using a house or offices made up of biological concrete. The aim of this study is to investigate and find out the person's opinion about staying in a house or offices made up of biological concrete. In this study, a questionnaire containing eight questions was prepared and distributed among 21 persons in Malaysia University of Technology including students, academic and non-academic staffs among which few of them was an expert in the field of biological concrete and others did not have any knowledge about the bioconcrete. Finally, the results obtained from the questionnaires were analyzed. The results showed that 81% of participants in this study would like to stay in a house or office made up of biological concrete. However, 38% of participants believe that staying in a house or office made of biological concrete can cause health related problems. The current research paper can be considered significant for architects and civil engineers to have the insight to look into the psychological aspects of using biological concrete for various applications in the field of construction.

    Healthcare wastes are a major challenge in public health and comprise all types of wastes generated by healthcare centers, research facilities, and laboratories. The aim of this study was surveying the knowledge and practice of nursing staff about sharp waste management in selected military (Tehran) and non- military (Qom) hospitals in 2012. This was a descriptive-analytical study on 143 nursing stuff in Military and Non-Military hospitals. Data was collected using a self-report questionnaire. Statistical tests such as the student t-test, one-way analysis of variance and Pearson correlation were used to data analysis. The mean age of participants was 32(±6.3) and the majority were female. The mean score of knowledge was 54.7(±14.4) and their knowledge classified on a moderate level. Also, the mean score of practice was 65.44(±11.6) and was classified on a moderate level. The means of these variables were higher among personnel of Military than Non-Military. There were positive correlations between knowledge, practice and age variables (P

    The use of cosmetics is very common among women in Iran. Given the importance of the use of mass media and the impact on the consumption of cosmetics, this study attempted to consider the influence of mass media on the use of cosmetics among women in Kashan. Using a standard designed questionnaire, the data were obtained from 800 women. Multi-stage cluster sampling was randomly carried out. The data were analyzed using SPSS statistical software. The findings showed that 59.9% of the participants believed that satellite programs have the greatest impact on the use of cosmetics. 33% of the participants who believed that mass media had significant influence in this regard; they had a constant tendency to use cosmetics. Mass media advertisements encourage women to consume cosmetics; therefore, introducing the real and appropriate cultural models via advertisements on mass media may have positive impacts on women to consume cosmetics properly.

    Nowadays, the change and dynamism of organizations are the basic principles; therefore, managers should modify the goals, plans and work procedures so that they can be compatible with the environment condition. The management of HSE is not excepted from this principle. The aim of this study was to evaluate the processes affecting HSE.
    This study was a cross-sectional and applied study using the review of relevant documentation, interviews and brainstorming with experts, and the reviews of Best Practice to identify the HSE's processes.
    After checking the HSE activities, the 5 processes of HSE training, managing the risks, events, emergencies and contractors and any changes in the other processes of the organization were also suggested.
    The results showed that a process approaching the form of an intervention programed can be provided in order to have a better interaction between the HSE activities and organizations processes and workplace health promotion for the HSE activities.
