This paper aims to study an enterprise resource planning (ERP) software selection problem. The primary goal of this paper is to propose a two‐phase procedure to select an ERP vendor and a suitable ERP software.

In the first phase of the proposed method the preliminary actions – such as constructing a project team, collecting all possible information about ERP vendors and systems, and identifying the ERP system characteristics – are established. In the second phase, the authors present a modular approach to ERP vendor and software selection and propose a 0‐1 programming model to minimize total costs associated with procurement and integration expenditures.

The proposed approach and the model are considered to be more useful for small manufacturing enterprises (SMEs).

In using the model for analyzing the data about a real case study that is a commercial SME and based on obtained results, some parameter values of the model for all SMEs are suggested.

Hepatitis C is one of the major health issues in both developed and developing countries. Hepatitis C virus (HCV) infection is more common in prisoners than in the general population. The purpose of this study was to determine the prevalence of HCV and its associated risk factors in Iranian male prisoners in Tehran.

In this cross-sectional study, the authors investigated the frequency and risk factors of hepatitis C infection among male prisoners in the Great Tehran Prison. Information on risk factors including the length of imprisonment, previous history of imprisonment, history of drug injection, history of tattooing, history of piercing, history of high-risk sex and family history of hepatitis C were extracted from patients’ records. To evaluate HCV status, blood samples were collected and tested.

In this study, 179 participants were included. Nine participants (5.0%, 95% CI, 2.3-9.3) were positive for hepatitis C. HCV infection was not significantly associated with age, marital status, education, previous history of imprisonment, length of imprisonment, piercing and high-risk sex; however, there was a significant association between a history of tattooing and a history of injecting drug use and Hepatitis C.

The prevalence of hepatitis C among male prisoners in Great Tehran Prison was 5% in this study, similar to recent studies on prisoners in Tehran. A history of drug injections as well as tattooing were the most important risk factors for hepatitis C in male prisoners.
