Estimating the costs of software development is one of the most important activities in software project management. Inaccuracies in such estimates may cause irreparable loss. A low estimate of the cost of projects will result in failure on delivery on time and indicates the inefficiency of the software development team. On the other hand, high estimates of resources and costs for a project wil...

Model integration is one of the most important and widely researched areas in the model management of Decision Support Systems (DSS). In current disaster management applications, independent DSS models handle specific decision-making needs but there are many advantages in combining these models. Therefore, there is a need for the selection and integration of such models. Previously, we presente...

Social psychology research on teams has shown that team performance improves when team members have a so-called shared mental model (SMM). We observe that a decision support system (DSS) and its user can be viewed as a team whose task is to make a (good) decision. Therefore we argue that it is important for good user-DSS team performance that they have a SMM. In this paper we make precise what ...

background: the present study assesses independent predictors of clinically important traumatic brain injury (citbi) in order to design a prognostic rule for identification of high risk children with mild head injury. materials and methods: in a retrospective cross-sectional study, 3,199 children with mild traumatic brain injury (tbi) brought to emergency ward of three hospitals in tehran, iran...

introduction: diagnostic values reported for ultrasonographic screening of acute appendicitis vary widely and are dependent on the operator’s skill, patient’s gender, weight, etc. the present study aimed to evaluate the effect of operator skill on the diagnostic accuracy of ultrasonography in detection of appendicitis by comparing the results of ultrasonography done by radiologists and emergenc...

introduction: doing chest x ray (cxr) for all trauma patients is not efficient and cost effective due to its low diagnostic value. the present study was designed aiming to evaluate the diagnostic accuracy of thoracic injury rule out criteria (tirc) in prediction of traumatic intra-thoracic injuries and need for cxr.  method: the present study is a prospective cross-sectional study that has been...

prediction of the outcome and severity of acute upper gastrointestinal bleeding (ugib) has significant importance in patient care, disposition, and determining the need for emergent endoscopy. recent international recommendations endorse using scoring systems for management of non-variceal ugib patients. to date, different scoring systems have been developed for predicting the risk of 30-day mo...

Effectiveness of Decision Support Systems (DSS’s) is enhanced through dynamic adaptation of support to the needs of the decision maker, to the problem, and to the decision context. We define this enhanced DSS’s as Adaptive Decision Support Systems (ADSS’s) and propose its architecture. In an ADSS, the decision maker controls the decision process. However, the system monitors the process to matc...
