    Aims: During the past decade, the application of engineering and managerial techniques for designing a variety of qualitative and quantitative risk assessment methods and modeling the consequences of accidents have had a great contribution to the promotion of safety in the industrial systems. The present study was conducted to identify and prioritize safety risks in one of the automotive industries. Risk management of the operation of transferring waste thinner from the paint shop represents a critical issue owing to special safety.
    Materials And Methods
    One of the most important theories for the modeling of events is the bowtie analyzing method. Bowtie is a qualitative analyzing method which incorporates managerial system techniques and provides a highly accurate analysis in the form of fault and event trees. In the present study, the process of risk identification and management was carried out using the Bowtie analyzing method and the obtained results were applied to the structure of a bowtie graph and the consequence was modeled using ALOHA software.
    Results
    In the study, the operation of transferring waste thinner from the paint shop of an automotive industry was examined. Possible safety risks that may happen during the loading and unloading operations of the waste thinners were detected using bowtie analyzing method and the modeling of fire at chemical tanker carrying thinner and also the modeling of BLEVE phenomenon was conducted. The results represent that the area, in which employees are stationed is at very high risk that in the event of a possible fire, the personnel will be quickly caught in fireballs caused by the burning of thinner.
    Conclusion
    According to the results, it was found that one of the administrative units is positioned inappropriately and incorrectly in the vicinity of thinner loading station that in the case of nondisplacement of the mentioned unit and the incident of fire or explosion in the place of loading and unloading of thinner, undoubtedly there would be fire at the mentioned administrative uni

    Aims: The trend of withdrawal from groundwater resources in Kashan plain has been increased during the recent 40 years. For example, the number of deep wells has been increased from 67 in 1965 to 927 in 2003. As a result, the well discharges and water quality have been diminishing. Hence, this research was aimed to study the salinity variation modeling in Kashan plain groundwater resource.
    Materials And Methods
    This descriptive research was done based on recorded data for some wells in Kashan plain. First, the data from 112 wells were considered then, 16 wells with more complete data were selected for analysis. Total dissolved solids (TDSs) were considered as the salinity index.
    Results
    The results showed that, in Kashan plain, the mean of salinity has been increased from 1190 mg/L to more than 1400 mg/L during 7 years. Although the salinity has been somewhat less after each annual precipitation, the trend is upward. Minimum and maximum of TDS were identified taken samples from wells number 27 and 47, respectively. Maximum rate of salinity was found in wells number 53 and 55, while the minimum was related to well number 54.
    Conclusions
    The groundwater salinity in Kashan plain has an upward trend. The groundwater salinity can be related to some major factors such as distance from Salt Lake, less annual precipitation, and more withdrawal from the aquifer in the recent decades. Since the later can be managed withdrawal, especially for agricultural activities have to be minimized as the most effective way for prevention of the groundwater quality degradation

    Aims: The present study was conducted to identify and prioritize Health, Safety, and Environment (HSE) risk in Loghman hospital. Risk
    management of hospitals represents a critical issue owing to special safety, health, biological and infection risks, and hospital wastes.
    Materials And Methods
    This study is, in terms of the purpose, an applied research. Statistical population includes 68 managers and experts
    of risk management in Loghman hospital of Iran. A targeted sampling method was used for sampling. Five points were selected to identify and
    evaluate the risks at which field visits were made and the checklists were completed. The identified risks were extracted from the checklists and
    worksheets for identification and evaluation of the risks were completed based on failure mode and effect analysis (FMEA) method. Priority of
    risks obtained by analytical hierarchy process technique was quiet close to that achieved by FMEA approach.
    Results
    Occurrence probability,
    severity, and detectability of HSE risks were identified using FMEA technique. According to the results, lack of emergency exit with normal
    weight of 0.143 has the highest priority, followed by lack of building strength (normal weight of 0.114), electricity (0.113), and biological
    contamination (0.107). Inconsistency rate was estimated close to zero (
    Conclusion
    Accordingto the results, Loghman hospital lacks emergency exit due to old nature of the building which causes a serious threat for both hospital and
    people. An emergency exit gate can be constructed for each floor that can be used in emergency events and hence, minimize the estimatedrisk. Considering low strength of the building due to its old nature, the hospital can be reconstructed through a sophisticated engineering plan.At first, this proposal may not be suitable owing to high cost; however, much higher cost will be imposed if a disaster occurs

    Background And Aim
    Renal transplantation is one of the main treatments of chronic renal disease that creates a more optimal condition and
    reduces the risk of fatality. The most common reason behind the functional problems of transplanted kidney in its initial postoperation phase
    is acute renal transplant rejection, the timely diagnosis of which would help the doctors, begin the required treatments immediately to maintain
    renal functionality, and prevent further irrecoverable damages. Therefore, identifying the variables which are accurate and reliable predictors of
    renal transplant rejection can be hugely beneficial.
    Materials And Methods
    In this historical cohort study, 87 nondiabetic patients with renal
    failure who had received treatments at Kidney Transplantation Department of Imam Reza and Ghaem Hospitals of Mashhad, Iran, were selected
    and their demographic and clinical characteristics were collected. Among these data, creatinine, fasting blood sugar (FBS) and serum insulin,
    thyroid‑stimulating hormone (TSH), and T3 and T4 hormones were measured four times after the transplant operation. Data were analyzed
    using SAS 9.3 and MedCalc 13 software. First, the missing data were imputed with appropriate imputation methods, and then using logistic
    regression and area under receiver operating characteristic (ROC) curve, the most important detectors of acute renal transplant rejection were
    determined. Significance level (α) was set at 0.01.
    Results
    Using logistic regression analysis and drawing ROC curves for average value of
    four measurements, the effect of serum creatinine and T4 hormone was found statistically significant (P
    Conclusion
    Results showedthat among six variables that were studied (creatinine, FBS, insulin, TSH, T3, and T4), serum creatinine and T4 hormone were statisticallysignificant and also were the most important of acute renal transplant rejection.

    Aims: Nursing and midwifery students experience multiple stressors in the clinical setting that can affect their proper functioning. Therefore,
    the objective of this research was the effective stressors in clinical education among nursing and midwifery students of Islamic Azad University,
    Mahabad in 2016.
    Materials And Methods
    This study was a cross‑sectional study of applied type. The statistical population was nursing and midwifery students of the Azad University of Mahabad in 2016. The sample size was selected in clinical setting to be 300 person. The data gathering tool was a esearcher‑made questionnaire consisting of two sections of demographic information and a section of the stressful factors of clinical education in eight domains and 106 items. The validity of this questionnaire was determined by content validity. Hence, thereliability of this tool was confirmed by a test–retest method with a correlation of 0.89. The partial least square (PLS) method, independentt‑test, and Friedman test were used for data analysis.
    Results
    The results showed that there is a positive and significant relationship betweenthe interpersonal communication, environmental factors, educational planning, personal–social factors, university education factors, unpleasant experiences, and clinical experiences with stress (P = 0.000). However, there was not a statistically significant relationship between the humiliating experiences and the feeling of tension in students (P ≤ 0.218). Furthermore, Friedman test showed that the most important stressoron students’ perception of their stress in the clinical environment is environmental factors. C
    onclusion: The results of stressful factors in clinicaleducation indicated lack of significance in all areas except for humiliating experiences area. Therefore, the authorities should take necessary steps to control and manage stress in students and increase the quality of education by holding workshops and the formation of the committeeor the community to examine these factors, given all the stressful areas in the clinical education setting, especially environmental factors
