常用医学搜索引擎简介   总被引:2,自引:0,他引:2  
搜索引擎(Search ing Engine)是检索Internet信息资源的一个重要的检索工具。搜索引擎网站的主要资源不是它的网页信息,而是它的索引数据库,其主要功能类似于传统图书馆的目录卡片,提供人们在Internet上查询并获取所需信息资源提供快速、便捷的检索途径。搜索引擎的原理[1],大致上有以下三个方面:从互联网上抓取网页→建立索引数据库→在索引数据中搜索排序。最后由页面生成系统将搜索结果的链接地址和页面内容摘要等组织起来返回给用户。医学搜索引擎其实也是一个医学专业网站,专门提供医学信息“检索”服务,它使用特有的程序把因特网上…  相似文献

The Internet stands at the forefront of telecommunications in medicine, including forensic medicine, since information technology (IT) has been able to revolutionize medical and scientific practices. Today, forensic physicians and professionals need to be familiar with the use of computers and the key applications of information technology: multimedia and the Internet. From the office, the forensic physician can communicate with other physicians by means of e-mail, take part in discussion groups, obtain information on meetings and get information from public libraries and various databases by means of file transfer protocol. The search among the huge amount of information is facilitated by the 'click and play' use of the Internet, by its increased ease and availability of access and by faster communications to an increasing number of accessible technical, scientific and biomedical resources. Therefore, it is useful to introduce some of the most frequent concepts encountered when exploring the Internet, to give simple references for any forensic physician exploring the Internet and to present typical Internet aspects by illustrations saved from worldwide websites and linked to the accompanying text. Some of the main forensic websites and basic Internet procedures are described, explaining how to search and exchange information in the domain of forensic medicine and sciences. Search engines and search procedures on the worldwide web are briefly explained. The aim of this paper is to give forensic physicians, scientists and law professionals some basic tools and references to access the vast possibilities of the Internet.  相似文献

BACKGROUND: Studies of the use of the World Wide Web to obtain medical knowledge have largely focused on patients. In particular, neither the international use of academic nephrology World Wide Web sites (websites) as primary information sources nor the use of search engines (and search strategies) to obtain medical information have been described. METHODS: Visits ("hits") to the Walter Reed Army Medical Center (WRAMC) Nephrology Service website from April 30, 2000, to March 14, 2001, were analyzed for the location of originating source using Webtrends, and search engines (Google, Lycos, etc.) were analyzed manually for search strategies used. RESULTS: From April 30, 2000 to March 14, 2001, the WRAMC Nephrology Service website received 1,007,103 hits and 12,175 visits. These visits were from 33 different countries, and the most frequent regions were Western Europe, Asia, Australia, the Middle East, Pacific Islands, and South America. The most frequent organization using the site was the military Internet system, followed by America Online and automated search programs of online search engines, most commonly Google. The online lecture series was the most frequently visited section of the website. Search strategies used in search engines were extremely technical. CONCLUSIONS: The use of "robots" by standard Internet search engines to locate websites, which may be blocked by mandatory registration, has allowed users worldwide to access the WRAMC Nephrology Service website to answer very technical questions. This suggests that it is being used as an alternative to other primary sources of medical information and that the use of mandatory registration may hinder users from finding valuable sites. With current Internet technology, even a single service can become a worldwide information resource without sacrificing its primary customers.  相似文献

Some consider the terms “forensic” and “legal” medicine to be synonymous but this is counter to the title of the Faculty of Forensic and Legal Medicine or the dual strands for progression to fellowship of the Australian College of Legal Medicine. The paper examines a very brief historical background to legal medicine and develops a definition of the strands thereof, namely legal and forensic medicine. It demonstrates that the two are different components of the application of medical knowledge upon the legal system. Legal medicine has greater relevance to civil and tort law, impacting upon patient care, whereas forensic medicine relates to criminal law and damage to, or by, patients.  相似文献

Teaching with computers   总被引:1,自引:0,他引:1  
Various methods of using computers in education have been presented. Although the interesting file, interactive video, and bibliographic searches stand on their own, a far better approach is to integrate them, so that the radiologist learning new techniques in interventional procedures, for instance, could search the current literature quickly and easily for new articles using the bibliographic search facility and could review interesting cases from the teaching file that pertained to the lesson at hand. One very important attempt to integrate some of these teaching functions in conjunction with other aspects of medical school administration and research has been the Integrated Academic Information Management Systems (IAIMS) Program of the National Library of Medicine. This program stems from a report created by the Association of American Medical Colleges (AAMC), which was funded originally by the National Library of Medicine. This program has funded several teaching institutions to first plan for an integrated approach to medical information (Fig. 7) and then implement prototype systems. As medical image management systems become available (see the article entitled "Digital Image Management: Networking, Display, and Archiving"), they will be a major component of these information networks and will be most important for teaching purposes. Integrating the teaching components described earlier with the medical image management system will be most important.  相似文献

Since the introduction of nuclear medicine in 1959, Korea accomplished a brilliant development in terms of both clinical practice and research activities, which was mainly due to the dedication of nuclear medicine specialists, consisting of physicians, technicians, and scientists, and strong support from the Korean Government. Now, Korea has 150 medical institutes, performing approximately 561,000 nuclear imaging procedures and 11.6 million in vitro studies in 2008, and ranked fourth in the number of presentations at the Annual Meeting of the Society of Nuclear Medicine (SNM) in 2008. The successful progress in this field has allowed Korea to focus on the international promotion of nuclear medicine, especially in the developing and underdeveloped countries. In consequence, the Asian Regional Cooperative Council for Nuclear Medicine (ARCCNM) was established in 2001, and Seoul hosted the 9th Congress of the World Federation of Nuclear Medicine and Biology (WFNMB) in 2006. In the future, Korea will strive to sustain its rate of advancement in the field and make every effort to share its progress and promote the exchange of scientific information at the international level.  相似文献

AURA is a free-text system designed to facilitate automatic documentation of radiological reports, with the goal of making the information in the reports accessible for case location, feedback, and statistical evaluation without changing the regular routine of the radiologist. A simple interactive search language makes retrieval easy. Search criteria can be formulated in medical terms and do not require programming ability.  相似文献

Evidence-based medicine originated at McMaster University, Hamilton, Ontario, Canada, where it was defined as "the integration of current best evidence with clinical expertise and patient values" by the Evidence-based Medicine Working Group led by Drs Gordon Guyatt and David Sackett. From this developed the McMaster University and National Health Service Centre for Evidence-Based Medicine, University of Oxford, paradigm of evidence-based practice, which consists of five steps that can be used by ordinary practitioners: formulate answerable questions with which to search for evidence, search the literature, appraise the retrieved evidence by using explicit methods, apply results to a patient or patient group, and evaluate one's evidence-based practice and clinical performance and practice. This communication is about the first two steps of this process. Step 1 provides a framework for more effective question formulation that improves subsequent literature searches. It works equally well for questions about diagnostic and interventional radiology. A clinical scenario for a diagnostic question is used to illustrate the formulation of an answerable question. This question is then used to illustrate step 2-how and where to search for evidence.  相似文献
