Introduction: Nowadays ionizing radiation has a considerable contribution in medical diagnostic and treatment. Using ionizing radiation is increasing rapidly, so biological effects of ionizing radiation should be considered more. X-rays in the range of diagnostic radiology have hazardous effects and risks that are defined as random effects. These effects obey the LNT hypothesis that occur at lo...

The present study aimed to determine the effect of risk management on supply chain management(case study: Saipa Company). This study was applied in terms of purpose and descriptive-correlational in terms of data collection method. The tools used in this study include the 29-item questionnaire. The statistical population of this study included 110 managers of Saipa Company in Tehran. In this stu...

the present paper aimed at studying the current models of credit portfolio management. there are currently three types of models which consider the risk of credit portfolio: the structural models (moody's kmv model, and credit- metrics model), the intensity models (the actuarial models) and the econometric models (the macro-factors model). the development of these three types of models is based...

conclusions the prevalence of msds among the nurses was high, and the occurrence of such disorders was found to be related to the scores of mapo and ptai indices. based on the results, these two indices can be used as appropriate tools to assess the risk of msds in patient handling by nursing staff. the risk of developing msds can be lowered through interventional programs, such as providing an...

The growing importance of enterprise risk management and the resulting integration efforts put the need for separate IT risk management frameworks in question. In this research we analyse common and distinct elements of the COSO enterprise risk management and ISACA Risk IT frameworks. The analysis affirms the hypothesis that separate IT risk management frameworks are redundant.

Tail risk refers to the risk associated with extreme values and is often affected by extremal dependence among multivariate extremes. Multivariate tail risk, as measured by a coherent risk measure of tail conditional expectation, is analyzed for multivariate regularly varying distributions. Asymptotic expressions for tail risk are established in terms of the intensity measure that characterizes...

background: the area of contaminated lands exposed to the health risk of environmental pollutants is a matter of argument. in this study, a new method was developed to estimate the amount of area that is exposed to higher than normal levels of cr, mn, and v. methods: overall, 170 soil samples were collected from the upper 10 cm of soil in an arid area in central part of iran in semnan province....

Cyber risks are an important point on the business agenda in every company, but they are difficult to assess due to the absence of reliable data and profound analyses. To improve this situation, we identify cyber losses from an operational risk database and analyze these with methods from the field of actuarial science. Specifically, we apply operational risk models in order to yield consistent...

high blood pressure control (hbpc) is a common goal of who and the world hypertension league (whl). the two important strategies in hbpc are identifying cardiovascular (cvd) risk factors and planning to modify controllable factors. this study was accomplished to determine the cvd risk factors in high blood pressure (hbp) patients of the rural population, residing in the babol region, north of i...
