objective: to evaluate the current scientific evidence for the applicability, safety and effectiveness of pathways of enhanced recovery after emergency surgery (eras). methods: we undertook a search using pubmed and cochrane databases for eras protocols in emergency cases. the search generated 65 titles; after eliminating the papers not meeting search criteria, we selected 4 cohort studies and ...
background: diabetes has become a daunting health and medical challenge as well as a hefty economic burden for societies over the past decades. this study was designed to shed light on the overall trend of research across iran regarding mental health status of diabetic patients. method: search process of the present study is part of search strategy of iran diabetes research roadmap (idrr) study...
Optimization method for e-learning document search with keywords which are derived from the keywords and descriptions in the meta-tag of web search results together with thesaurus engine is proposed. 15 to 20% of improvement on hit rate of search performance is confirmed with the proposed search engine. KeywordsSearch engine; e-learning content; thesaurus engine.
Current rate selection algorithms are dominated by probebased approaches that search for the best transmission rate using trial-and-error. When operating over a dynamic channel, probe-based techniques can perform poorly since they inefficiently search for the moving target presented by the constantly changing channel. We have developed a channelaware rate adaptation algorithm CHARM that respond...
today, with rapid growth of the world wide web and creation of internet sites and online text resources, text summarization issue is highly attended by various researchers. extractive-based text summarization is an important summarization method which is included of selecting the top representative sentences from the input document. when, we are facing into large data volume documents, the extr...
introduction: users’ performance and their interaction with information retrieval systems can be observed in development of their mental models. users, especially users of health, use mental models to facilitate their interactions with these systems and incomplete or incorrect models can cause problems for them . the aim of this study was the adjustment and development of health user’s mental m...
this paper presents a strategy for using harmony search algorithm in facility layout optimization problems. in this paper an adapted harmony search algorithm is developed for solving facility layout optimization problems. this method finds an optimal facility arrangement in an existing layout. two real-world case studies are employed to demonstrate the efficiency of this model. a comparison is ...
Abstract Background: Hospitals are the most important health organization and consume major part of health system`s budgets. Downsizing is one of the strategies used for providing suitable services in hospitals. This study was conducted to do a systematic search for hospital downsizing methods and theirs consequences in order to choose suitable method for Iran. Materials & Methods: Related ...
Background & Objectives: This investigation was prompted by the growing importance of nested case-control studies and the increasing frequency with which they are done in epidemiologic research. After a brief explanation of nested case-control studies, we evaluate the trends in research methodology over the last decade, especially with regard to cohort, case-control, and nested case-control des...
Practical design of tall frame-tube and diagrids are formulated as two discrete optimization problems searching for minimal weight undercodified constraints under gravitational and wind loading due to Iranian codes of practice for steel structures (Part 6 & Part 10). Particular encoding of design vector is proposed to efficiently handle both problems leading to minimal search space. Two types o...
