background: the purpose of this work is to discover and analyze errors and incidents in some radiotherapy centers, and to introduce methods that could reduce their occurrences, especially those which had happened due to the use of improper and inadequate equipment. this work is a first step toward clarifying the role of education in a risk-conscious culture, and changing the attitude of radioth...

introduction: health care organizations, especially hospitals, must focus on patient safety as their main strategy. cultural change is the most important challenge that they are faced with in creating a safe system. the present article aims to improve the patient safety culture with an assessment of the safety in fatemeh zahra hospital, najafabad, iran. methods: this descriptive and cross-secti...

patients and methods a questionnaire was developed by a departmental checklist focus group, which aimed to identify the perception of health care checklists in general as well as specific checklists for routine and crisis situations in anesthesia. furthermore participants were asked regarding their perception of performing routine anesthesia and managing crisis situations without any cognitive ...

In this short communication, we describe the shortcomings and pitfalls of a commonly used method to detect ground materials that relies on setting thresholds for normalized difference indices. We analyze critically present some experimental results USGS ECOSTRESS spectral libraries real Sentinel-2 Landsat-8 images. demonstrate risk commission errors provide suggestions reduce it.

conclusion the use of ahp method can be promising for fostering the evaluation method and subsequently promotion of the efficiency and effectiveness of the radiology departments. the present model can fill in the gap in the accreditation system of the country’s hospitals in respect with ranking and comparing them considering the significance and value of each individual criteria and standard. a...

introduction: during radiotherapy, high accuracy in the dose delivery is required because there is a strong  relationship between the absorbed dose, local tumor control and particularly the normal tissue damage. in  many institutions, in vivo dosimetry using diodes is performed to check the actual dose delivered. in general,  the uncertainty in the dose delivered should fall within  ± 5% of the...

The magnitude of posterior medial frontal cortex (pMFC) activity during commission of an error has been shown to relate to adaptive posterror changes in response behavior on the trial immediately following. In the present article, we examined neural activity during and after error commission to identify its relationship to sustained posterror behavior changes that led to performance improvement...

We examine the impact of outside purchase contracts on firm risk and firm capital structure. We find that firms with more outside purchase contracts have less risky cash flows. Despite these less risky cash flows, firms with these contracts also have less financial leverage especially when they operate in high value-added industries. Examining firm financing decisions, we document that firms wi...
