    Now a days due to duplicate documents in the World Wide Web while crawling, indexing and relevancy. Search engine gives huge number of redundancy data. Because of that, storing data is waste of rankings quality, resources, which is not convenient for users. To optimized this limitation a normalization rules is use to transform all duplicate URLs into the same canonical form and further optimized the result using Jaccard similarity function which optimized the similar text present in the content of the URL’s these function define some threshold value to reduce the duplication

    Packrat parsing is a type of recursive decent parsing with guaranteed liner time parsing. For this,memoization technique is implemented in which all parsing results are memorized to avoid repetitive scanningof inputs in case of backtracking. The issue with this technique is large heap consumption for memoization whichout weigh the benefits. In many situations the developers need to make a tough decision of not implementingpackrat parsing despite the possibility of exponential time parsing. In this paper we present our developedtechnique to avoid such a tough choice. The heap consumption is upper bounded since memorized results arestored in buffer, capacity of which is decided at runtime depending on memory available in the machine. Thisdynamic buffer allocation is implemented by us in Mouse parser. This implementation achieves stableperformance against a variety of inputs with backtracking activities while utilizing appropriate size of memoryfor heap

    : Social networks have turned into a piece of the human life beginning from shearing information like texts, photos, messages; many have begun share most recent news. Young people will unreservedly surrender individual information to join social networks on the internet. The networking website offer the clear route for individuals to have a straightforward social nearness through web. They give the virtual condition to individuals to share every single movement, their advantage, and their hover of associate with their family, companions, or even the obscure with the so much sharing, programmer hackers and hoodlums have discovered simple approaches to take individual information through these networking sites. This call for progress in security reason to protect again hackers which frame the premise of this exploration in this paper we will talk about a portion of the security and security concerns, attacks and an engineering for secure demand trade of information between client . This design enhances the customization of profile. Our examination recommends that exclusive a legitimate information of the hacking methodologies will enhance the best guard in the war against the cyber attacks

    The promise of competency-based education in the health professions for improving global health

    Abstract Competency-based education (CBE) provides a useful alternative to time-based models for preparing health professionals and constructing educational programs. We describe the concept of ‘competence’ and ‘competencies’ as well as the critical curricular implications that derive from a focus on ‘competence’ rather than ‘time’. These implications include: defining educational outcomes, developing individualized learning pathways, setting standards, and the centrality of valid assessment so as to reflect stakeholder priorities. We also highlight four challenges to implementing CBE: identifying the health needs of the community, defining competencies, developing self-regulated and flexible learning options, and assessing learners for competence. While CBE has been a prominent focus of educational reform in resource-rich countries, we believe it has even more potential to align educational programs with health system priorities in more resource-limited settings. Because CBE begins with a careful consideration of the competencies desired in the health professional workforce to address health care priorities, it provides a vehicle for integrating the health needs of the country with the values of the profession.http://deepblue.lib.umich.edu/bitstream/2027.42/112402/1/12960_2012_Article_314.pd

    Pharmacological assessments of polyphenolic extract of Cymbopogon citratus leaves in rodent model of parkinson’s disease

    Parkinson's disease (PD) is amongst the most common age-related neurodegenerative disorders. Natural compounds, especially the polyphenols have gained great interest as potential therapeutic agents in recent research. Thus, the present study was designed to evaluate the effect of polyphenolic extract of Cymbopogon citratus (C. Citratus) leaves in animal models of PD. In the given study PD was induced by administration of reserpine (5 mg/kg/day, i.p for 5 consecutive days), haloperidol (1 mg/kg, i.p.), in experimental animals. The symptoms of PD such as tremors, akinesia, rigidity and catalepsy were evaluated. Ethanolic extract of Cymbopogon citratus (CC) in doses of 100, 200 & 400mg/kg were administered per oral (PO). The L-dopa and carbidopa (30 mg/kg, PO) combination was used as a positive standard drug.  Behavioural studies such as locomotor activity were performed. In catalepsy model, there is significant reduction in catalepsy duration in CC (100, 200, 400mg/kg) treated group as compared to the haloperidol group. In reserpine model, there is significant decrease of muscular rigidity, tremors, and akinesia in groups treated with CC (100, 200, 400mg/kg) dose dependently. Thus, the present study suggests the beneficial role of C. citratus leaves polyphenolic extract in treatment of parkinsonian like symptoms.

    Targeting and structuring information resource use: A path toward informed clinical decisions

    Full text link
    A core skill for all physicians to master is that of information manager. Despite a rapidly expanding set of electronic and print-based information resorces, clinicians continue to answer their clinical queries predominantly through informal or formal consultation. Even as new tools are brought to market, the majority of them present information in a rigid fashion, presenting cumbersome user interfaces and inflexible data presentation. The need to rethink the structure of electronic information is paramount to improving the use of evidence at the bedside. As new tools are developed and educators teach clinians to use them, the context for use of information resources must be considered, with special attention to physician work flow, following the three paths outlined in this article. The process will be facilitated greatly by promoting evidence-based practice for the care of patients in the hospital and clinic setting.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/35026/1/1340240504_ftp.pd

    How do doctors use information in real-time? A qualitative study of internal medicine resident precepting

    Full text link
    Background  Despite the importance of evidence-based medicine in medical education, little observational research exists on how doctors-in-training seek and use evidence from information resources in ambulatory care. Objective  To describe information exchange behaviour by internal medicine residents and attendings in ambulatory resident clinic precepting rooms. Design  We observed resident behaviour and audiotaped resident–attending doctor interactions during precepting sessions. Participants  Participating residents included 70 of an eligible 89 residents and 28 of 34 eligible attendings from one large academic internal medicine residency programme in the Midwestern USA. Residents were observed during 95 separate precepting interactions at four ambulatory sites. Approach  Using a qualitative approach, we analysed transcripts and field notes of observed behaviours and interactions looking for themes of information exchange. Coders discussed themes which were refined using feedback from an interdisciplinary panel. Results  Four themes of information exchange behaviour emerged: (i) questioning behaviours that were used as part of the communication process in which the resident and attending doctor could reason together; (ii) searching behaviour of non-human knowledge sources occurred in a minority of precepting interations; (iii) unsolicited knowledge offering and (iv) answering behaviours were important means of exchanging information. Conclusions  Most clinic interactions between resident and attending doctors relied heavily on spoken deliberation without resorting to the scientific literature or other published information resources. These observations suggest a range of factors that may moderate information exchange behaviour in the precepting context including relationships, space and efficiency. Future research should aim to more readily adapt information resources to the relationships and practice context of precepting.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/72879/1/j.1365-2753.2006.00752.x.pd

    Do we practice what we preach? A qualitative assessment of resident–preceptor interactions for adherence to evidence‐based practice

    Full text link
    Background  Evidence‐based medicine (EBM) is important in training doctors for high‐quality care. Yet little is known about whether ambulatory precepting incorporates the concepts and principles of EBM. Methods  The authors observed and audiotaped 95 internal medicine residency precepting interactions and rated interactions using a qualitative analytic template consisting of three criteria: (1) presence of clinical questions; (2) presence of an evidence‐based process; and (3) resident ability to articulate a clinical question. Results  Sixty‐seven of 95 audio tapes (71%) were of acceptable quality to allow template analysis. Thirty (45%) contained explicit clinical questions; 11 (16%) included an evidence‐based process. Resident ability to articulate a clinical question when prompted was rated as at least ‘fair’ in 59 of 67 interactions (88%). Conclusions  EBM was not optimally implemented in these clinics. Future research could explore more systematically what factors facilitate or impair the use of EBM in the real‐time ambulatory training context.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/99027/1/j.1365-2753.2008.00966.x.pd
