Background: One way to reduce medical errors associated with physician orders is computerized physician order entry (CPOE) software. This study was conducted to compare prescription orders between 2 groups before and after CPOE implementation in a hospital. Methods: We conducted a before-after prospective study in 2 intensive care unit (ICU) wards (as intervention and control wards) in the larg...

We survey principles of model checking techniques for the automatic analysis of reactive systems. The use of model checking is exemplified by an analysis of the Needham-Schroeder public key protocol. We then formally define transition systems, temporal logic, ω-automata, and their relationship. Basic model checking algorithms for linearand branching-time temporal logics are defined, followed by...

A key problem in mobile and ubiquitous computing is that of setting up an association between a pair of devices so that they may communicate securely over a wireless network. It is particularly important to be able to solve this problem for spontaneous associations, which must not depend on preexisting security values such as certificates, and when the only means of identifying the target devic...

baladieh as a new administration, has started its operation from the constitutional era, and in reza shah's reign continued its undertakings more seriously in the field of urban planning, cleaning, and supply needs of the citizens. part of the baladieh actions was in the field of public health. documents clearly indicate the baladieh's attempt to reorganize community's health sta...

the main purpose of this article is to draw the map of the discipline of public administration. due to the heuristic nature of the research and also regarding the fact that the investigation is a uni-variable study, the research does not require any hypothesis. the main question of the present research is: ‘based on the scientific articles of “isi” covering the years 2000 to 2010, how feasible ...

Estimates of the costs and consequences of many types of public policy proposals play an important role in the development and adoption of particular policy programs. Estimates of the same, or similar, policies that employ different modeling approaches can yield widely divergent results. Such divergence often undermines effective policy-making. These problems are particularly prominent for heal...

Context and aim: The Danish hospital sector is facing a significant rebuilding programme, driven by a political desire to concentrate activity in fewer and larger hospitals. Our aim is to analyse whether the current configuration of Danish hospitals is subject to scale economies that may justify such plans and to estimate an optimal hospital size. Methods: We estimate cost functions using panel...

We exhibit a hash-based storage auditing scheme which is provably secure in the random-oracle model (ROM), but easily broken when one instead uses typical indifferentiable hash constructions. This contradicts the widely accepted belief that the indifferentiability composition theorem from [27] applies to any cryptosystem. We characterize the uncovered limitations of indifferentiability by showi...
