    Hunter, William John Forbes

    1998-12-01

    This thesis describes an action research investigation of improvements to instruction in General Chemistry at Purdue University. Specifically, the study was conducted to guide continuous reform of curriculum materials delivered via the World Wide Web by involving students, instructors, and curriculum designers. The theoretical framework for this study was based upon constructivist learning theory and knowledge claims were developed using an inductive analysis procedure. This results of this study are assertions made in three domains: learning chemistry content via the World Wide Web, learning about learning via the World Wide Web, and learning about participation in an action research project. In the chemistry content domain, students were able to learn chemical concepts that utilized 3-dimensional visualizations, but not textual and graphical information delivered via the Web. In the learning via the Web domain, the use of feedback, the placement of supplementary aids, navigation, and the perception of conceptual novelty were all important to students' use of the Web. In the participation in action research domain, students learned about the complexity of curriculum. development, and valued their empowerment as part of the process.

  2. World wide developments in shortwall and wide web mining techniques

    Energy Technology Data Exchange (ETDEWEB)

    Pollard, T

    1975-11-01

    The paper describes the progress to date with continuous pillar extraction, and how the typical longwall powered support has been modified to be both strong enough and stable enough to provide roof support for very wide webs. It also describes the operating systems which have been specially designed. The next stages of development are discussed, particularly the provision of continuous conveyor haulage in place of the present-day shuttle car. The author suggests that marrying American coal-getting technology and British roof support technology might increase productivity.

  3. Embedded Web Technology: Applying World Wide Web Standards to Embedded Systems

    2002-01-01

    Embedded Systems have traditionally been developed in a highly customized manner. The user interface hardware and software along with the interface to the embedded system are typically unique to the system for which they are built, resulting in extra cost to the system in terms of development time and maintenance effort. World Wide Web standards have been developed in the passed ten years with the goal of allowing servers and clients to intemperate seamlessly. The client and server systems can consist of differing hardware and software platforms but the World Wide Web standards allow them to interface without knowing about the details of system at the other end of the interface. Embedded Web Technology is the merging of Embedded Systems with the World Wide Web. Embedded Web Technology decreases the cost of developing and maintaining the user interface by allowing the user to interface to the embedded system through a web browser running on a standard personal computer. Embedded Web Technology can also be used to simplify an Embedded System's internal network.

    2007-01-01

    The results are in, and the winner is...the World Wide Web! An online survey conducted by the CNN news group ranks the World Wide Web-invented at CERN--as the most wonderful of the seven modern wonders of the world. (See Bulletin No. 49/2006.) There is currently no speculation about whether they would have had the same results had they distributed the survey by post. The World Wide Web won with a whopping 50 per cent of the votes (3,665 votes). The runner up was CERN again, with 16 per cent of voters (1130 votes) casting the ballot in favour of the CERN particle accelerator. Stepping into place behind CERN and CERN is 'None of the Above' with 8 per cent of the votes (611 votes), followed by the development of Dubai (7%), the bionic arm (7%), China's Three Gorges Damn (5%), The Channel Tunnel (4%), and France's Millau viaduct (3%).

  17. Collecting behavioural data using the world wide web: considerations for researchers.

    Science.gov (United States)

    Rhodes, S D; Bowie, D A; Hergenrather, K C

    2003-01-01

    To identify and describe advantages, challenges, and ethical considerations of web based behavioural data collection. This discussion is based on the authors' experiences in survey development and study design, respondent recruitment, and internet research, and on the experiences of others as found in the literature. The advantages of using the world wide web to collect behavioural data include rapid access to numerous potential respondents and previously hidden populations, respondent openness and full participation, opportunities for student research, and reduced research costs. Challenges identified include issues related to sampling and sample representativeness, competition for the attention of respondents, and potential limitations resulting from the much cited "digital divide", literacy, and disability. Ethical considerations include anonymity and privacy, providing and substantiating informed consent, and potential risks of malfeasance. Computer mediated communications, including electronic mail, the world wide web, and interactive programs will play an ever increasing part in the future of behavioural science research. Justifiable concerns regarding the use of the world wide web in research exist, but as access to, and use of, the internet becomes more widely and representatively distributed globally, the world wide web will become more applicable. In fact, the world wide web may be the only research tool able to reach some previously hidden population subgroups. Furthermore, many of the criticisms of online data collection are common to other survey research methodologies.

  4. Remote sensing education and Internet/World Wide Web technology

    Science.gov (United States)

    Griffith, J.A.; Egbert, S.L.

    2001-01-01

    Remote sensing education is increasingly in demand across academic and professional disciplines. Meanwhile, Internet technology and the World Wide Web (WWW) are being more frequently employed as teaching tools in remote sensing and other disciplines. The current wealth of information on the Internet and World Wide Web must be distilled, nonetheless, to be useful in remote sensing education. An extensive literature base is developing on the WWW as a tool in education and in teaching remote sensing. This literature reveals benefits and limitations of the WWW, and can guide its implementation. Among the most beneficial aspects of the Web are increased access to remote sensing expertise regardless of geographic location, increased access to current material, and access to extensive archives of satellite imagery and aerial photography. As with other teaching innovations, using the WWW/Internet may well mean more work, not less, for teachers, at least at the stage of early adoption. Also, information posted on Web sites is not always accurate. Development stages of this technology range from on-line posting of syllabi and lecture notes to on-line laboratory exercises and animated landscape flyovers and on-line image processing. The advantages of WWW/Internet technology may likely outweigh the costs of implementing it as a teaching tool.

    Geographical information system has come into the Web Service times now. In this paper, Web3D applications have been developed based on our developed Gridjet platform, which provides a more effective solution for massive 3D geo-dataset sharing in distributed environments. Web3D services enabling web users could access the services as 3D scenes, virtual geographical environment and so on. However, Web3D services should be shared by thousands of essential users that inherently distributed on different geography locations. Large 3D geo-datasets need to be transferred to distributed clients via conventional HTTP, NFS and FTP protocols, which often encounters long waits and frustration in distributed wide area network environments. GridJet was used as the underlying engine between the Web 3D application node and geo-data server that utilizes a wide range of technologies including the one of paralleling the remote file access, which is a WAN/Grid-optimized protocol and provides "local-like" accesses to remote 3D geo-datasets. No change in the way of using software is required since the multi-streamed GridJet protocol remains fully compatible with existing IP infrastructures. Our recent progress includes a real-world test that Web3D applications as Google Earth over the GridJet protocol beats those over the classic ones by a factor of 2-7 where the transfer distance is over 10,000 km.

    Sendall, D M

    1997-01-01

    The World-Wide Web was first developed as a tool for collaboration in the high energy physics community. From there it spread rapidly to other fields, and grew to its present impressive size. As an easy way to access information, it has been a great success, and a huge number of medical applications have taken advantage of it. But there is another side to the Web, its potential as a tool for collaboration between people. Medical examples include telemedicine and teaching. New technical developments offer still greater potential in medical and other fields. This paper gives some background to the early development of the World-Wide Web, a brief overview of its present state with some examples relevant to medicine, and a look at the future.

    The world-wide sensor web has become a very useful technique for monitoring the physical world at spatial and temporal scales that were previously impossible. Yet we believe that the full potential of sensor web has thus far not been revealed. In order to harvest the world-wide sensor web's full potential, a geospatial cyberinfrastructure is needed to store, process, and deliver large amount of sensor data collected worldwide. In this paper, we first define the issue of the sensor web long tail followed by our view of the world-wide sensor web architecture. Then, we introduce the Geospatial Cyberinfrastructure for Environmental Sensing (GeoCENS) architecture and explain each of its components. Finally, with demonstration of three real-world powered-by-GeoCENS sensor web applications, we believe that the GeoCENS architecture can successfully address the sensor web long tail issue and consequently realize the world-wide sensor web vision.

    2007-01-01

    To design and develop a World Wide Web-based education program that will allow trainees to interactively learn and improve the diagnostic capability of detecting pulmonary nodules on chest radiographs. Chest radiographs with known diagnosis were retrieved and selected from our institutional clinical archives. A database was constructed by sorting radiographs into three groups: normal, nodule, and false positive (i.e., nodule-like focal opacity). Each nodule was assigned with the degree of detectability: easy, intermediate, difficult, and likely missed. Nodules were characterized by their morphology (well-defined, ill-defined, irregular, faint) and by other associated pathologies or potentially obscuring structures. The Web site was organized into four sections: study, test, record and information. The Web site allowed a user interactively to undergo the training section appropriate to the user's diagnostic capability. The training was enhanced by means of clinical and other pertinent radiological findings included in the database. The outcome of the training was tested with clinical test radiographs that presented nodules or false positives with varying diagnostic difficulties. A World Wide Web-based education program is a promising technique that would allow trainees to interactively learn and improve the diagnostic capability of detecting and characterizing pulmonary nodules

    Full Text Available There is little published research on the role of consultants in technology adoption. Given the increasing popularity of the World Wide Web in commercial environments and the number of consultants now offering web development services, some analysis into the effects of their engagement would be of benefit. In an extension of an ongoing study, an existing sample of 113 World Wide Web adopters was used to examine the nature of World Wide Web site use with respect to consultant and Internet Service Provider (ISP engagement. Analysis was also conducted into the use of consultants and ISPs as developers and maintainers of these sites. This preliminary research finds a number of interesting outcomes. No significant relationship is found between consultant or ISP engagement and World Wide Web site use, regardless of whether the consultant was engaged as site developer or site maintainer. The study raises a number of additional findings that are of interest but are not directly related to this study. These findings merit further research.

The authors have developed demonstration software that illustrates several safeguards data systems using the resources of the Internet and Web to access and review data. This Web demo allows the user to directly observe sensor data, to analyze simulated safeguards data, and to view simulated on-line inventory data. Future activities include addressing the technical and security issues associated with using the Web to interface with existing and planned monitoring systems at nuclear facilities. Some of these issues are authentication, encryption, transmission of large quantities of data, and data compression

    Full Text Available Two methods were employed in this study of the use of the World Wide Web by business: first, a sample of 300 businesses with Web sites, across a wide range of industry types, was examined, by selecting (rather than sampling companies from the Yahoo! directory. The sites were investigated in relation to several areas - the purpose of the Web site, the use being made of electronic mail and the extent to which multi-media was being utilised. In addition, any other aspects of the site which were designed to make it more interesting to potential customers were also noted. Secondly, an electronic-mail questionnaire was sent to 222 of the 300 companies surveyed: that is, those that provided an e-mail address for contact. 14 were returned immediately due to unknown addresses or technical problems. Of the remaining 208, 102 replies were received, five of which were of no relevance, leaving 97 completed questionnaires to examine; a response rate of 47%, which is surprisingly good for a survey of this kind.

    Nelson, Michael L.; Bianco, David J.

    1995-01-01

    NASA Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming the first NASA installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a more concentrated focus on technology transfer to both aerospace and non-aerospace industry. Use of WWW and NCSA Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution and integration of many technology transfer and technology awareness applications. This paper describes several of these innovative applications, including the on-line presentation of the entire Technology OPportunities Showcase (TOPS), an industrial partnering showcase that exists on the Web long after the actual 3-day event ended. The NASA Technical Report Server (NTRS) provides uniform access to many logically similar, yet physically distributed NASA report servers. WWW is also the foundation of the Langley Software Server (LSS), an experimental software distribution system which will distribute LaRC-developed software. In addition to the more formal technology distribution projects, WWW has been successful in connecting people with technologies and people with other people.

    1997-05-01

    In this paper, we present the design architecture and the implementation status of WebPresent - a world wide web based tele-presentation tool. This tool allows a physician to use a conference server workstation and make a presentation of patient cases to a geographically distributed audience. The audience consists of other physicians collaborating on patients' health care management and physicians participating in continuing medical education. These physicians are at several locations with networks of different bandwidth and capabilities connecting them. Audiences also receive the patient case information on different computers ranging form high-end display workstations to laptops with low-resolution displays. WebPresent is a scalable networked multimedia tool which supports the presentation of hypertext, images, audio, video, and a white-board to remote physicians with hospital Intranet access. WebPresent allows the audience to receive customized information. The data received can differ in resolution and bandwidth, depending on the availability of resources such as display resolution and network bandwidth.

    Purpose - The World-Wide Web (W-3) initiative is a practical project designed to bring a global information universe into existence using available technology. This paper seeks to describe the aims, data model, and protocols needed to implement the "web" and to compare them with various contemporary systems. Design/methodology/approach - Since Vannevar Bush's article, men have dreamed of extending their intellect by making their collective knowledge available to each individual by using machines. Computers provide us two practical techniques for human-knowledge interface. One is hypertext, in which links between pieces of text (or other media) mimic human association of ideas. The other is text retrieval, which allows associations to be deduced from the content of text. The W-3 ideal world allows both operations and provides access from any browsing platform. Findings - Various server gateways to other information systems have been produced, and the total amount of information available on the web is...

    Orthotopic liver transplant (OLTx) has evolved to a successful surgical management for end-stage liver diseases. Awareness and information about OLTx is an important tool in assisting OLTx recipients and people supporting them, including non-transplant clinicians. The study aimed to investigate the nature and quality of liver transplant-related patient information on the World Wide Web. Four common search engines were used to explore the Internet by using the key words 'Liver transplant'. The URL (unique resource locator) of the top 50 returns was chosen as it was judged unlikely that the average user would search beyond the first 50 sites returned by a given search. Each Web site was assessed on the following categories: origin, language, accessibility and extent of the information. A weighted Information Score (IS) was created to assess the quality of clinical and educational value of each Web site and was scored independently by three transplant clinicians. The Internet search performed with the aid of the four search engines yielded a total of 2,255,244 Web sites. Of the 200 possible sites, only 58 Web sites were assessed because of repetition of the same Web sites and non-accessible links. The overall median weighted IS was 22 (IQR 1 - 42). Of the 58 Web sites analysed, 45 (77%) belonged to USA, six (10%) were European, and seven (12%) were from the rest of the world. The median weighted IS of publications originating from Europe and USA was 40 (IQR = 22 - 60) and 23 (IQR = 6 - 38), respectively. Although European Web sites produced a higher weighted IS [40 (IQR = 22 - 60)] as compared with the USA publications [23 (IQR = 6 - 38)], this was not statistically significant (p = 0.07). Web sites belonging to the academic institutions and the professional organizations scored significantly higher with a median weighted IS of 28 (IQR = 16 - 44) and 24(12 - 35), respectively, as compared with the commercial Web sites (median = 6 with IQR of 0 - 14, p = .001).

    CERN Multimedia

    2004-01-01

    At the end of the 1980s, the Internet was already a valuable tool to scientists, allowing them to exchange e-mails and to access powerful computers remotely. A more simple means of sharing information was needed, however, and CERN, with its long tradition of informatics and networking, was the ideal place to find it. Moreover, hundreds of scientists from all over the world were starting to work together on preparations for the experiments at the Large Electron-Positron (LEP) collider. In 1989, Tim Berners-Lee (see photo), a young scientist working at CERN, drafted a proposal for an information-management system combining the internet, personal computers and computer-aided document consultation, known as hypertext. In 1990 he was joined by Robert Cailliau and the weaving of the World Wide Web began in earnest, even though only two CERN computers were allocated to the task at the time. The Web subsequently underwent a steady expansion to include the world's main particle physics institutes. The Web was not the...

    2013-02-01

    The World Wide Web is increasingly becoming an important source of information for healthcare professionals. However, finding reliable information from unauthoritative Web sites to inform healthcare can pose a challenge to nurses. A study, using grounded theory, was undertaken in two phases to understand how qualified nurses judge the quality of Web nursing information. Data were collected using semistructured interviews and focus groups. An explanatory framework that emerged from the data showed that the judgment process involved the application of forms of knowing and modes of cognition to a range of evaluative tasks and depended on the nurses' critical skills, the time available, and the level of Web information cues. This article mainly focuses on the six evaluative tasks relating to assessing user-friendliness, outlook and authority of Web pages, and relationship to nursing practice; appraising the nature of evidence; and applying cross-checking strategies. The implications of these findings to nurse practitioners and publishers of nursing information are significant.

    Ashford, Miriam Thiel; Olander, Ellinor K; Ayers, Susan

    2016-06-01

    One relatively new and increasingly popular approach of increasing access to treatment is Web-based intervention programs. The advantage of Web-based approaches is the accessibility, affordability, and anonymity of potentially evidence-based treatment. Despite much research evidence on the effectiveness of Web-based interventions for anxiety found in the literature, little is known about what is publically available for potential consumers on the Web. Our aim was to explore what a consumer searching the Web for Web-based intervention options for anxiety-related issues might find. The objectives were to identify currently publically available Web-based intervention programs for anxiety and to synthesize and review these in terms of (1) website characteristics such as credibility and accessibility; (2) intervention program characteristics such as intervention focus, design, and presentation modes; (3) therapeutic elements employed; and (4) published evidence of efficacy. Web keyword searches were carried out on three major search engines (Google, Bing, and Yahoo-UK platforms). For each search, the first 25 hyperlinks were screened for eligible programs. Included were programs that were designed for anxiety symptoms, currently publically accessible on the Web, had an online component, a structured treatment plan, and were available in English. Data were extracted for website characteristics, program characteristics, therapeutic characteristics, as well as empirical evidence. Programs were also evaluated using a 16-point rating tool. The search resulted in 34 programs that were eligible for review. A wide variety of programs for anxiety, including specific anxiety disorders, and anxiety in combination with stress, depression, or anger were identified and based predominantly on cognitive behavioral therapy techniques. The majority of websites were rated as credible, secure, and free of advertisement. The majority required users to register and/or to pay a program access

  5. Infant Gastroesophageal Reflux Information on the World Wide Web.

    Balgowan, Regina; Greer, Leah C; D'Auria, Jennifer P

    2016-01-01

    The purpose of this study was to describe the type and quality of health information about infant gastroesophageal reflux (GER) that a parent may find on the World Wide Web. The data collection tool included evaluation of Web site quality and infant GER-specific content on the 30 sites that met the inclusion criteria. The most commonly found content categories in order of frequency were management strategies, when to call a primary care provider, definition, and clinical features. The most frequently mentioned strategies included feeding changes, infant positioning, and medications. Thirteen of the 30 Web sites included information on both GER and gastroesophageal reflux disease. Mention of the use of medication to lessen infant symptoms was found on 15 of the 30 sites. Only 10 of the 30 sites included information about parent support and coping strategies. Pediatric nurse practitioners (PNPs) should utilize well-child visits to address the normalcy of physiologic infant GER and clarify any misperceptions parents may have about diagnosis and the role of medication from information they may have found on the Internet. It is critical for PNPs to assist in the development of Web sites with accurate content, advise parents on how to identify safe and reliable information, and provide examples of high-quality Web sites about child health topics such as infant GER.

    We briefly describe a system for forms-based, work-flow management that helps members of a software development team overcome geographical barriers to collaboration. Our system, called the Web Integrated Software Environment (WISE), is implemented as a World-Wide-Web service that allows for management and measurement of software development projects based on dynamic analysis of change activity in the workflow. WISE tracks issues in a software development process, provides informal communication between the users with different roles, supports to-do lists, and helps in software process improvement. WISE minimizes the time devoted to metrics collection and analysis by providing implicit delivery of messages between users based on the content of project documents. The use of a database in WISE is hidden from the users who view WISE as maintaining a personal 'to-do list' of tasks related to the many projects on which they may play different roles.

    1999-01-01

    The World Wide Web currently boasts millions of users in the United States alone and is likely to continue to expand both as a marketplace and as an advertising environment. Three experiments explored advertising in the Web environment, in particular memory for ads as they appear in everyday use across the Web. Experiments 1 and 2 examined the effect of advertising repetition on the retention of familiar and less familiar brand names, respectively. Experiment 1 demonstrated that repetition of a banner ad within multiple web pages can improve recall of familiar brand names, and Experiment 2 demonstrated that repetition can improve recognition of less familiar brand names. Experiment 3 directly compared the retention of familiar and less familiar brand names that were promoted by static and dynamic ads and demonstrated that the use of dynamic advertising can increase brand name recall, though only for familiar brand names. This study also demonstrated that, in the Web environment, much as in other advertising environments, familiar brand names possess a mnemonic advantage not possessed by less familiar brand names. Finally, data regarding Web usage gathered from all experiments confirm reports that Web usage among males tends to exceed that among females.

    Bailey, Shana D; D'Auria, Jennifer P; Haushalter, Jamie P

    2013-01-01

    The purpose of this study was to explore and describe the type and quality of information on infantile colic that a parent might access on the World Wide Web. Two checklists were used to evaluate the quality indicators of 24 Web sites and the colic-specific content. Fifteen health information Web sites met more of the quality parameters than the nine commercial sites. Eight Web sites included information about colic and infant abuse, with six being health information sites. The colic-specific content on 24 Web sites reflected current issues and controversies; however, the completeness of the information in light of current evidence varied among the Web sites. Strategies to avoid complications of parental stress or infant abuse were not commonly found on the Web sites. Pediatric professionals must guide parents to reliable colic resources that also include emotional support and understanding of infant crying. A best evidence guideline for the United States would eliminate confusion and uncertainty about which colic therapies are safe and effective for parents and professionals.

    2013-01-01

    Mentoring, for physicians and surgeons in training, is advocated as an essential adjunct in work-based learning, providing support in career and non-career related issues. The World Wide Web (WWW) has evolved, as a technology, to become more interactive and person centric, tailoring itself to the individual needs of the user. This changing technology may open new avenues to foster mentoring in medicine. DESIGN, SYSTEMATIC REVIEW, MAIN OUTCOME MEASURES: A search of the MEDLINE database from 1950 to 2012 using the PubMed interface, combined with manual cross-referencing was performed using the following strategy: ("mentors"[MeSH Terms] OR "mentors"[All Fields] OR "mentor"[All Fields]) AND ("internet"[MeSH Terms] OR "internet"[All Fields]) AND ("medicine"[MeSH Terms] OR "medicine"[All Fields]) AND ("humans"[MeSH Terms] AND English[lang]). Abstracts were screened for relevance (UJ) to the topic; eligibility for inclusion was simply on screening for relevance to online mentoring and web-based technologies. Forty-five papers were found, of which 16 were relevant. All studies were observational in nature. To date, all medical mentoring applications utilizing the World Wide Web have enjoyed some success limited by Web 1.0 and 2.0 technologies. With the evolution of the WWW through 1.0, 2.0 and 3.0 generations, the potential for meaningful tele- and distance mentoring has greatly improved. Some engagement has been made with these technological advancements, however further work is required to fully realize the potential of these technologies.

    New web-based technologies provide an excellent opportunity for sharing and accessing information and using web as a platform for interaction and collaboration. Although several specialized tools are available for analyzing DNA sequence information, conventional web-based tools have not been utilized for bioinformatics applications. We have developed a novel algorithm and implemented it for searching species-specific genomic sequences, DNA barcodes, by using popular web-based methods such as Google. We developed an alignment independent character based algorithm based on dividing a sequence library (DNA barcodes) and query sequence to words. The actual search is conducted by conventional search tools such as freely available Google Desktop Search. We implemented our algorithm in two exemplar packages. We developed pre and post-processing software to provide customized input and output services, respectively. Our analysis of all publicly available DNA barcode sequences shows a high accuracy as well as rapid results. Our method makes use of conventional web-based technologies for specialized genetic data. It provides a robust and efficient solution for sequence search on the web. The integration of our search method for large-scale sequence libraries such as DNA barcodes provides an excellent web-based tool for accessing this information and linking it to other available categories of information on the web.

    The World Wide Web ("the Web") is a macrocosm of resources that can be overwhelming. Often the sheer volume of material available causes one to give up in despair before finding information of any use. The Web is such a popular resource that it cannot be ignored. Two of the biggest challenges to finding good information on the Web are knowing where to start and judging whether the information gathered is pertinent and credible. This article addresses these two challenges and introduces the reader to a variety of ophthalmology and vision science resources on the World Wide Web.

  5. Network dynamics: The World Wide Web

    Adamic, Lada Ariana

    Despite its rapidly growing and dynamic nature, the Web displays a number of strong regularities which can be understood by drawing on methods of statistical physics. This thesis finds power-law distributions in website sizes, traffic, and links, and more importantly, develops a stochastic theory which explains them. Power-law link distributions are shown to lead to network characteristics which are especially suitable for scalable localized search. It is also demonstrated that the Web is a "small world": to reach one site from any other takes an average of only 4 hops, while most related sites cluster together. Additional dynamical properties of the Web graph are extracted from diffusion processes.

    This study was designed to ascertain the quality of patient information available on the World Wide Web on the topic of knee arthroscopy. For the purpose of quality analysis, we used a pool of 232 search results obtained from 7 different search engines. We used a modified assessment questionnaire to assess the quality of these Web sites. This questionnaire was developed based on similar studies evaluating Web site quality and includes items on illustrations, accessibility, availability, accountability, and content of the Web site. We also compared results obtained with different search engines and tried to establish the best possible search strategy to attain the most relevant, authentic, and adequate information with minimum time consumption. For this purpose, we first compared 100 search results from the single most commonly used search engine (AltaVista) with the pooled sample containing 20 search results from each of the 7 different search engines. The search engines used were metasearch (Copernic and Mamma), general search (Google, AltaVista, and Yahoo), and health topic-related search engines (MedHunt and Healthfinder). The phrase "knee arthroscopy" was used as the search terminology. Excluding the repetitions, there were 117 Web sites available for quality analysis. These sites were analyzed for accessibility, relevance, authenticity, adequacy, and accountability by use of a specially designed questionnaire. Our analysis showed that most of the sites providing patient information on knee arthroscopy contained outdated information, were inadequate, and were not accountable. Only 16 sites were found to be providing reasonably good patient information and hence can be recommended to patients. Understandably, most of these sites were from nonprofit organizations and educational institutions. Furthermore, our study revealed that using multiple search engines increases patients' chances of obtaining more relevant information rather than using a single search

    The World Wide Web is increasingly important for medical education. Internet served pages may also be used on a local hard disk or CD-ROM without a network or server. This allows authors to reuse existing content and provide access to users without a network connection. CD-ROM offers several advantages over network delivery of Web pages for several applications. However, creating Web pages for CD-ROM requires careful planning. Issues include file names, relative links, directory names, default pages, server created content, image maps, other file types and embedded programming. With care, it is possible to create server based pages that can be copied directly to CD-ROM. In addition, Web pages on CD-ROM may reference Internet served pages to provide the best features of both methods.

  13. The World Wide Web and Technology Transfer at NASA Langley Research Center

    1994-01-01

    NASA Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming the first NASA installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a more concentrated focus on technology transfer to both aerospace and non-aerospace industry. Use of the WWW and NCSA Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution and integration of many technology transfer applications. This paper describes several of these innovative applications, including the on-line presentation of the entire Technology Opportunities Showcase (TOPS), an industrial partnering showcase that exists on the Web long after the actual 3-day event ended. During its first year on the Web, LaRC also developed several WWW-based information repositories. The Langley Technical Report Server (LTRS), a technical paper delivery system with integrated searching and retrieval, has proved to be quite popular. The NASA Technical Report Server (NTRS), an outgrowth of LTRS, provides uniform access to many logically similar, yet physically distributed NASA report servers. WWW is also the foundation of the Langley Software Server (LSS), an experimental software distribution system which will distribute LaRC-developed software with the possible phase-out of NASA's COSMIC program. In addition to the more formal technology distribution projects, WWW has been successful in connecting people with technologies and people with other people. With the completion of the LaRC reorganization, the Technology Applications Group, charged with interfacing with non-aerospace companies, opened for business with a popular home page.

    Full Text Available The transition of traditional library collections to digital or virtual collections presented the librarian with new opportunities. The Internet, Web en-vironment and associated sophisticated tools have given the librarian a new dynamic role to play and serve the new information based society in bet-ter ways than hitherto. Because of the powerful features of Web i.e. distributed, heterogeneous, collaborative, multimedia, multi-protocol, hyperme-dia-oriented architecture, World Wide Web has revolutionized the way people access information, and has opened up new possibilities in areas such as digital libraries, virtual libraries, scientific information retrieval and dissemination. Not only the world is becoming interconnected, but also the use of Internet and Web has changed the fundamental roles, paradigms, and organizational culture of libraries and librarians as well. The article describes the limitless scope of Internet and Web, the existence of the librarian in the changing environment, parallelism between information sci-ence and information technology, librarians and intelligent agents, working of intelligent agents, strengths, weaknesses, threats and opportunities in-volved in the relationship between librarians and the Web. The role of librarian in Internet and Web environment especially as intermediary, facilita-tor, end-user trainer, Web site builder, researcher, interface designer, knowledge manager and sifter of information resources is also described.

    Compact optical discs (CDs and the World Wide Web (the Web are two mechanisms that contemporary libraries extensively use for digitized information storage, dissemination, and retrieval. The Web features an unparalleled global accessibility free from many previously known temporal and spatial restrictions. Its real-time update capability is impossible for CDs. Web-based information delivery can reduce the cost in hardware and software ownership and management of a local library, and provide one-to-one zcustomization to better serve library's clients. The current limitations of the Web include inadequate speed in data transmission, particularly for multimedia applications, and its insufficient reliability, search capabilities, and security. In comparison, speed, quality, portability, and reliability are the current advantages of CDs over the Web. These features, together with the trend in the PC industry and market, suggest that CDs will exist and continue to develop. CD/Web hybrids can combine the best of both developing mechanisms and offer optimal results. Through a comparison of CDs and the Web, it is argued that the functionality and unique features of a technology determine its future.

  18. Efficacy of the World Wide Web in K-12 environmental education

    York, Kimberly Jane

    1998-11-01

    Despite support by teachers, students, and the American public in general, environmental education is not a priority in U.S. schools. Teachers face many barriers to integrating environmental education into K--12 curricula. The focus of this research is teachers' lack of access to environmental education resources. New educational reforms combined with emerging mass communication technologies such as the Internet and World Wide Web present new opportunities for the infusion of environmental content into the curriculum. New technologies can connect teachers and students to a wealth of resources previously unavailable to them. However, significant barriers to using technologies exist that must be overcome to make this promise a reality. Web-based environmental education is a new field and research is urgently needed. If teachers are to use the Web meaningfully in their classrooms, it is essential that their attitudes and perceptions about using this new technology be brought to light. Therefore, this exploratory research investigates teachers' attitudes toward using the Web to share environmental education resources. Both qualitative and quantitative methods were used to investigate this problem. Two surveys were conducted---self-administered mail survey and a Web-based online survey---to elicit teachers perceptions and comments about environmental education and the Web. Preliminary statistical procedures including frequencies, percentages and correlational measures were performed to interpret the data. In-depth interviews and participant-observation methods were used during an extended environmental education curriculum development project with two practicing teachers to gain insights into the process of creating curricula and placing it online. Findings from the both the mail survey and the Web-based survey suggest that teachers are interested in environmental education---97% of respondents for each survey agreed that environmental education should be taught in K

    Silicon dendritic web, ribbon form of silicon and capable of fabrication into solar cells with greater than 15% AMl conversion efficiency, was produced from the melt without die shaping. Improvements were made both in the width of the web ribbons grown and in the techniques to replenish the liquid silicon as it is transformed to web. Through means of improved thermal shielding stress was reduced sufficiently so that web crystals nearly 4.5 cm wide were grown. The development of two subsystems, a silicon feeder and a melt level sensor, necessary to achieve an operational melt replenishment system, is described. A gas flow management technique is discussed and a laser reflection method to sense and control the melt level as silicon is replenished is examined.

First, it should serve the immediate needs of the researchers in the field, namely, conferences, journals, news, funds, etc. This is currently available on the site, but can be extended and improved if needed. Second, the site will reflect the connection between Condensed matter physics and the technological breakthroughs that drive the economy. Third, the site will carry an educational mission helping educate the general public, and on the other hand, help young people to start their careers in the field. The content of the DCMP Web site is under active development. It depends upon wide involvement of DCMP members.

We show that the emergent double-hierarchical structure with distinct distributions of out- and in-links is comparable with the observed empirical data when the control parameter (average graph flexibility β) is kept in the range β=3-4. We then explore the Web graph by simulating (a) Web crawling to determine size and depth of connected components, and (b) a random walker that discovers the structure of connected subgraphs with dominant attractor and promoter nodes. A random walker that adapts its move strategy to mimic local node linking preferences is shown to have a short access time to "important" nodes on the Web graph.

    Full Text Available The trend towards mobile devices usage has made it possible for the Web to be conceived not only as an information space but also as a ubiquitous platform where users perform all kinds of tasks. In some cases, users access the Web with native mobile applications developed for well-known sites, such as, LinkedIn, Facebook, and Twitter. These native applications might offer further (e.g., location-based functionalities to their users in comparison with their corresponding Web sites because they were developed with mobile features in mind. However, many Web applications have no native counterpart and users access them using a mobile Web browser. Although the access to context information is not a complex issue nowadays, not all Web applications adapt themselves according to it or diversely improve the user experience by listening to a wide range of sensors. At some point, users might want to add mobile features to these Web sites, even if those features were not originally supported. In this paper, we present a novel approach to allow end users to augment their preferred Web sites with mobile features. We support our claims by presenting a framework for mobile Web augmentation, an authoring tool, and an evaluation with 21 end users.

    Various studies have been carried out since 2005 under the leadership of Ministry of Environment and Urbanism of Turkey, in order to observe the quality of air in Turkey, to develop new policies and to develop a sustainable air quality management strategy. For this reason, a national air quality monitoring network has been developed providing air quality indices. By this network, the quality of the air has been continuously monitored and an important information system has been constructed in order to take precautions for preventing a dangerous situation. The biggest handicap in the network is the data access problem for instant and time series data acquisition and processing because of its proprietary structure. Currently, there is no service offered by the current air quality monitoring system for exchanging information with third party applications. Within the context of this work, a web service has been developed to enable location based querying of the current/past air quality data in Turkey. This web service is equipped with up-todate and widely preferred technologies. In other words, an architecture is chosen in which applications can easily integrate. In the second phase of the study, a web-based application was developed to test the developed web service and this testing application can perform location based acquisition of air-quality data. This makes it possible to easily carry out operations such as screening and examination of the area in the given time-frame which cannot be done with the national monitoring network.

    In the past 20 years, society has witnessed the following landmark scientific advances: (i) the sequencing of the human genome, (ii) the distribution of software by the open source movement, and (iii) the invention of the World Wide Web. Together, these advances have provided a new impetus for clinical software development: developers now translate the products of human genomic research into clinical software tools; they use open-source programs to build them; and they use the Web to deliver them. Whilst this open-source component-based approach has undoubtedly made clinical software development easier, clinical software projects are still hampered by problems that traditionally accompany the software process. This study describes the development of the BOADICEA Web Application, a computer program used by clinical geneticists to assess risks to patients with a family history of breast and ovarian cancer. The key challenge of the BOADICEA Web Application project was to deliver a program that was safe, secure and easy for healthcare professionals to use. We focus on the software process, problems faced, and lessons learned. Our key objectives are: (i) to highlight key clinical software development issues; (ii) to demonstrate how software engineering tools and techniques can facilitate clinical software development for the benefit of individuals who lack software engineering expertise; and (iii) to provide a clinical software development case report that can be used as a basis for discussion at the start of future projects. We developed the BOADICEA Web Application using an evolutionary software process. Our approach to Web implementation was conservative and we used conventional software engineering tools and techniques. The principal software development activities were: requirements, design, implementation, testing, documentation and maintenance. The BOADICEA Web Application has now been widely adopted by clinical geneticists and researchers. BOADICEA Web

    Full Text Available Various studies have been carried out since 2005 under the leadership of Ministry of Environment and Urbanism of Turkey, in order to observe the quality of air in Turkey, to develop new policies and to develop a sustainable air quality management strategy. For this reason, a national air quality monitoring network has been developed providing air quality indices. By this network, the quality of the air has been continuously monitored and an important information system has been constructed in order to take precautions for preventing a dangerous situation. The biggest handicap in the network is the data access problem for instant and time series data acquisition and processing because of its proprietary structure. Currently, there is no service offered by the current air quality monitoring system for exchanging information with third party applications. Within the context of this work, a web service has been developed to enable location based querying of the current/past air quality data in Turkey. This web service is equipped with up-todate and widely preferred technologies. In other words, an architecture is chosen in which applications can easily integrate. In the second phase of the study, a web-based application was developed to test the developed web service and this testing application can perform location based acquisition of air-quality data. This makes it possible to easily carry out operations such as screening and examination of the area in the given time-frame which cannot be done with the national monitoring network.

    Transgenic crops among the most controversial "science and society" issues of recent years. Because of the complex techniques involved in creating these crops and the polarized debate over their risks and beliefs, a critical need has arisen for accessible and balanced information on this technology. World Wide Web sites offer several advantages for disseminating information on a fast-changing technical topic, including their global accessibility; and their ability to update information frequently, incorporate multimedia formats, and link to networks of other sites. An alliance between two complementary web sites at Colorado State University and the University of Nebraska-Lincoln takes advantage of the web environment to help fill the need for public information on crop genetic engineering. This article describes the objectives and features of each site. Viewership data and other feedback have shown these web sites to be effective means of reaching public audiences on a complex scientific topic.

    1998-01-01

    World Wide Web (W3) technologies such as the Hypertext Transfer Protocol (HTTP) and the Java object-oriented programming environment offer a powerful, yet relatively inexpensive, framework for distributed application software development. This paper describes the design of a real-time payload control and monitoring system that was developed with W3 technologies at NASA Ames Research Center. Based on Java Development Toolkit (JDK) 1.1, the system uses an event-driven "publish and subscribe" approach to inter-process communication and graphical user-interface construction. A C Language Integrated Production System (CLIPS) compatible inference engine provides the back-end intelligent data processing capability, while Oracle Relational Database Management System (RDBMS) provides the data management function. Preliminary evaluation shows acceptable performance for some classes of payloads, with Java's portability and multimedia support identified as the most significant benefit.

    2009-10-01

    Full Text Available Abstract Background A number of tools for the examination of linkage disequilibrium (LD patterns between nearby alleles exist, but none are available for quickly and easily investigating LD at longer ranges (>500 kb. We have developed a web-based query tool (GLIDERS: Genome-wide LInkage DisEquilibrium Repository and Search engine that enables the retrieval of pairwise associations with r2 ≥ 0.3 across the human genome for any SNP genotyped within HapMap phase 2 and 3, regardless of distance between the markers. Description GLIDERS is an easy to use web tool that only requires the user to enter rs numbers of SNPs they want to retrieve genome-wide LD for (both nearby and long-range. The intuitive web interface handles both manual entry of SNP IDs as well as allowing users to upload files of SNP IDs. The user can limit the resulting inter SNP associations with easy to use menu options. These include MAF limit (5-45%, distance limits between SNPs (minimum and maximum, r2 (0.3 to 1, HapMap population sample (CEU, YRI and JPT+CHB combined and HapMap build/release. All resulting genome-wide inter-SNP associations are displayed on a single output page, which has a link to a downloadable tab delimited text file. Conclusion GLIDERS is a quick and easy way to retrieve genome-wide inter-SNP associations and to explore LD patterns for any number of SNPs of interest. GLIDERS can be useful in identifying SNPs with long-range LD. This can highlight mis-mapping or other potential association signal localisation problems.

    Rains, Stephen A

    2014-01-01

    Uncertainty management theory was applied in the present study to offer one theoretical explanation for how individuals use the World Wide Web to acquire health information and to help better understand the implications of the Web for information seeking. The diversity of information sources available on the Web and potential to exert some control over the depth and breadth of one's information-acquisition effort is argued to facilitate uncertainty management. A total of 538 respondents completed a questionnaire about their uncertainty related to cancer prevention and information-seeking behavior. Consistent with study predictions, use of the Web for information seeking interacted with respondents' desired level of uncertainty to predict their actual level of uncertainty about cancer prevention. The results offer evidence that respondents who used the Web to search for cancer information were better able than were respondents who did not seek information to achieve a level of uncertainty commensurate with the level of uncertainty they desired.

    2002-01-01

    This study was undertaken to determine the quality of information on the Internet regarding laparoscopy. Four popular World Wide Web search engines were used with the key word "laparoscopy." Advertisements, patient- or physician-directed information, and controversial material were noted. A total of 14,030 Web pages were found, but only 104 were unique Web sites. The majority of the sites were duplicate pages, subpages within a main Web page, or dead links. Twenty-eight of the 104 pages had a medical product for sale, 26 were patient-directed, 23 were written by a physician or group of physicians, and six represented corporations. The remaining 21 were "miscellaneous." The 46 pages containing educational material were critically reviewed. At least one of the senior authors found that 32 of the pages contained controversial or misleading statements. All of the three senior authors (LKN, NAO, GAF) independently agreed that 17 of the 46 pages contained controversial information. The World Wide Web is not a reliable source for patient or physician information about laparoscopy. Authenticating medical information on the World Wide Web is a difficult task, and no government or surgical society has taken the lead in regulating what is presented as fact on the World Wide Web.

    Visualization tools for biological data are often limited in their ability to interactively integrate data at multiple scales. These computational tools are also typically limited by two-dimensional displays and programmatic implementations that require separate configurations for each of the user's computing devices and recompilation for functional expansion. Towards overcoming these limitations we have developed "ePlant" (http://bar.utoronto.ca/eplant) - a suite of open-source world wide web-based tools for the visualization of large-scale data sets from the model organism Arabidopsis thaliana. These tools display data spanning multiple biological scales on interactive three-dimensional models. Currently, ePlant consists of the following modules: a sequence conservation explorer that includes homology relationships and single nucleotide polymorphism data, a protein structure model explorer, a molecular interaction network explorer, a gene product subcellular localization explorer, and a gene expression pattern explorer. The ePlant's protein structure explorer module represents experimentally determined and theoretical structures covering >70% of the Arabidopsis proteome. The ePlant framework is accessed entirely through a web browser, and is therefore platform-independent. It can be applied to any model organism. To facilitate the development of three-dimensional displays of biological data on the world wide web we have established the "3D Data Display Initiative" (http://3ddi.org).

    Silicon dendritic web, a single crystal ribbon shaped during growth by crystallographic forces and surface tension (rather than dies), is a highly promising base material for efficient low cost solar cells. The form of the product smooth, flexible strips 100 to 200 microns thick, conserves expensive silicon and facilitates automation of crystal growth and the subsequent manufacturing of solar cells. These characteristics, coupled with the highest demonstrated ribbon solar cell efficiency-15.5%-make silicon web a leading candidate to achieve, or better, the 1986 Low Cost Solar Array (LSA) Project cost objective of 50 cents per peak watt of photovoltaic output power. The main objective of the Web Program, technology development to significantly increase web output rate, and to show the feasibility for simultaneous melt replenishment and growth, have largely been accomplished. Recently, web output rates of 23.6 sq cm/min, nearly three times the 8 sq cm/min maximum rate of a year ago, were achieved. Webs 4 cm wide or greater were grown on a number of occassions.

    2003-05-07

    WIRED (World-Wide Web Interactive Remote Event Display) is a framework, written in the Java{trademark} language, for building High Energy Physics event displays. An event display based on the WIRED framework enables users of a HEP collaboration to visualize and analyze events remotely using ordinary WWW browsers, on any type of machine. In addition, event displays using WIRED may provide the general public with access to the research of high energy physics. The recent introduction of the object-oriented Java{trademark} language enables the transfer of machine independent code across the Internet, to be safely executed by a Java enhanced WWW browser. We have employed this technology to create a remote event display in WWW. The combined Java-WWW technology hence assures a world wide availability of such an event display, an always up-to-date program and a platform independent implementation, which is easy to use and to install.

    In response to a 1995 NASA SPDS announcement of support for preservation and distribution of important data sets online, the Geophysical Institute, University of Alaska Fairbanks, Alaska, proposed to provide World Wide Web access to the Poker Flat Auroral All-sky Camera images in real time. The Poker auroral all-sky camera is located in the Davis Science Operation Center at Poker Flat Rocket Range about 30 miles north-east of Fairbanks, Alaska, and is connected, through a microwave link, with the Geophysical Institute where we maintain the data base linked to the Web. To protect the low light-level all-sky TV camera from damage due to excessive light, we only operate during the winter season when the moon is down. The camera and data acquisition is now fully computer controlled. Digital images are transmitted each minute to the Web linked data base where the data are available in a number of different presentations: (1) Individual JPEG compressed images (1 minute resolution); (2) Time lapse MPEG movie of the stored images; and (3) A meridional plot of the entire night activity.

    2015-08-01

    Remote operation and diagnostic systems for particle accelerators have been developed for beam operation and maintenance in various situations. Even though fully remote experiments are not necessary, the remote diagnosis and maintenance of the accelerator is required. Considering remote-operation operator interfaces (OPIs), the use of standard protocols such as the hypertext transfer protocol (HTTP) is advantageous, because system-dependent protocols are unnecessary between the remote client and the on-site server. Here, we have developed a client system based on WebSocket, which is a new protocol provided by the Internet Engineering Task Force for Web-based systems, as a next-generation Web-based OPI using the Experimental Physics and Industrial Control System Channel Access protocol. As a result of this implementation, WebSocket-based client systems have become available for remote operation. Also, as regards practical application, the remote operation of an accelerator via a wide area network (WAN) faces a number of challenges, e.g., the accelerator has both experimental device and radiation generator characteristics. Any error in remote control system operation could result in an immediate breakdown. Therefore, we propose the implementation of an operator intervention system for remote accelerator diagnostics and support that can obviate any differences between the local control room and remote locations. Here, remote-operation Web-based OPIs, which resolve security issues, are developed.

  8. Affordances of students' using the World Wide Web as a publishing medium in project-based learning environments

    Science.gov (United States)

    Bos, Nathan Daniel

    This dissertation investigates the emerging affordance of the World Wide Web as a place for high school students to become authors and publishers of information. Two empirical studies lay groundwork for student publishing by examining learning issues related to audience adaptation in writing, motivation and engagement with hypermedia, design, problem-solving, and critical evaluation. Two models of student publishing on the World Wide Web were investigated over the course of two 11spth grade project-based science curriculums. In the first curricular model, students worked in pairs to design informative hypermedia projects about infectious diseases that were published on the Web. Four case studies were written, drawing on both product- and process-related data sources. Four theoretically important findings are illustrated through these cases: (1) multimedia, especially graphics, seemed to catalyze some students' design processes by affecting the sequence of their design process and by providing a connection between the science content and their personal interest areas, (2) hypermedia design can demand high levels of analysis and synthesis of science content, (3) students can learn to think about science content representation through engagement with challenging design tasks, and (4) students' consideration of an outside audience can be facilitated by teacher-given design principles. The second Web-publishing model examines how students critically evaluate scientific resources on the Web, and how students can contribute to the Web's organization and usability by publishing critical reviews. Students critically evaluated Web resources using a four-part scheme: summarization of content, content, evaluation of credibility, evaluation of organizational structure, and evaluation of appearance. Content analyses comparing students' reviews and reviewed Web documents showed that students were proficient at summarizing content of Web documents, identifying their publishing

    1997-08-01

    The World Wide Web (WWW) is a burgeoning information resource that can be utilized for current awareness and assistance in manuscript preparation and submission. The ever changing and expanding nature of the WWW allows it to provide up to the minute information, but this inherent changeability often makes information access difficult. To assist nutrition scientists in locating useful information about nutritional science journals on the WWW, this article critically reviews and describes the WWW sites for seventeen highly ranked nutrition and dietetics journals. Included in each annotation are the site's title, web address or Universal Resource Locator (URL), journal ranking and site authorship. Also listed is whether or not the site makes available the guidelines for authors, tables of contents, abstracts, online ordering, as well as information about the editorial board. This critical survey illustrates that the information on the web, regardless of its authority, is not of equal quality.

    2012-01-01

    With the advent of the World Wide Web, historic images previously having limited distributions are now widely available. As tobacco use has evolved, so have images of nurses related to smoking. Using a systematic search, the purpose of this article is to describe types of images of nurses and smoking available on the World Wide Web. Approximately 10,000 images of nurses and smoking published over the past century were identified through search engines and digital archives. Seven major themes were identified: nurses smoking, cigarette advertisements, helping patients smoke, "naughty" nurse, teaching women to smoke, smoking in and outside of health care facilities, and antitobacco images. The use of nursing images to market cigarettes was known but the extent of the use of these images has not been reported previously. Digital archives can be used to explore the past, provide a perspective for understanding the present, and suggest directions for the future in confronting negative images of nursing.

    Full Text Available The rapid expansion occurring in World-Wide Web activity is beginning to make the concepts of ‘global hypermedia’ and ‘universal document readership’ realistic objectives of the new revolution in information technology. One consequence of this increase in usage is that educators and students are becoming more aware of the diversity of the knowledge base which can be accessed via the Internet. Although computerised databases and information services have long played a key role in bioinformatics these same resources can also be used to provide core materials for teaching and learning. The large datasets and arch ives th at have been compiled for biomedical research can be enhanced with the addition of a variety of multimedia elements (images. digital videos. animation etc.. The use of this digitally stored information in structured and self-directed learning environments is likely to increase as activity across World-Wide Web increases.

    This study aimed to assess the quality of information available on the World Wide Web for patients undergoing thyroidectomy. The first 50 web-links generated by internet searches using the five most popular search engines and the key word 'thyroidectomy' were evaluated using the Lida website validation instrument (assessing accessibility, usability and reliability) and the Flesch Reading Ease Score. We evaluated 103 of a possible 250 websites. Mean scores (ranges) were: Lida accessibility, 48/63 (27-59); Lida usability, 36/54 (21-50); Lida reliability, 21/51 (4-38); and Flesch Reading Ease, 43.9 (2.6-77.6). The quality of internet health information regarding thyroidectomy is variable. High ranking and popularity are not good indicators of website quality. Overall, none of the websites assessed achieved high Lida scores. In order to prevent the dissemination of inaccurate or commercially motivated information, we recommend independent labelling of medical information available on the World Wide Web.

  2. Web X-Ray: Developing and Adopting Web Best Practices in Enterprises

    2016-12-01

    Full Text Available The adoption of Semantic Web technologies constitutes a promising approach to data structuring and integration, both for public and private usage. While these technologies have been around for some time, their adoption is behind overall expectations, particularly in the case of Enterprises. Having that in mind, we developed a Semantic Web Implementation Model that measures and facilitates the implementation of the technology. The advantages of using the model proposed are two-fold: the model serves as a guide for driving the implementation of the Semantic Web as well as it helps to evaluate the impact of the introduction of the technology. The model was adopted by 19 enterprises in an Action Research intervention of one year with promising results: according to the model's scale, in average, all enterprises evolved from a 6% evaluation to 46% during that period. Furthermore, practical implementation recommendations, a typical consulting tool, were developed and adopted during the project by all enterprises, providing important guidelines for the identification of a development path that may be adopted on a larger scale. Meanwhile, the project also outlined that most enterprises were interested in an even broader scope of the Implementation Model and the ambition of a "All Web Technologies" approach arose. One model that could embrace the observable overlapping of different Web generations, namely the Web of Documents, the Social Web, the Web of Data and, ultimately, the Web of Context. One model that could combine the evaluation and guidance for all enterprises to follow. That's the goal of the undergoing "Project Web X-ray" that aims to involve 200 enterprises in the adoption of best practices that may lead to their business development based on Web technologies. This paper presents a case of how Action Research promoted the simultaneous advancement of academic research and enterprise development and introduces the framework and opportunities

    Bryson, E.

    Ever since my introduction to the World Wide Web (WWW), it's been love at first byte. Searching on the WWW is similar to being able to go to a public library and allow yourself to be transported to any other book or library around the world by looking at a reference or index and clicking your heels together like Dorothy did in "The Wizard of Oz", only the clicking is done with a computer mouse. During this presentation, we will explore the WWW protocols which allow clients and servers to communicate on the Internet. We will demonstrate the ease with which users can navigate the virtual tidal wave of information available with a mere click of a button. In addition, the workshop will discuss the revolutionary aspects of this network information system and how it's impacting our libraries as a primary mechanism for rapid dissemination of knowledge.

    Gavrin, Jonathan

    2009-01-01

    In my last Internet-related article, I speculated that social networking would be the coming wave in the effort to share knowledge among experts in various disciplines. At the time I did not know that a palliative care site on the World Wide Web (WWW), palliativedrugs.com, already provided the infrastructure for sharing expert knowledge in the field. The Web site is an excellent traditional formulary but it is primarily devoted to "unlicensed" ("off-label") use of medications in palliative care, something we in the specialty often do with little to support our interventions except shared knowledge and experience. There is nothing fancy about this Web site. In a good way, its format is a throwback to Web sites of the 1990s. In only the loosest sense can one describe it as "multimedia." Yet, it provides the perfect forum for expert knowledge and is a "must see" resource. Its existing content is voluminous and reliable, filtered and reviewed by renowned clinicians and educators in the field. Although its origin and structure were not specifically designed for social or professional networking, the Web site's format makes it a natural way for practitioners around the world to contribute to an ever-growing body of expertise in palliative care.

    1999-04-01

    Nowadays the World Wide Web (WWW) is an established service used by people all over the world. Most of them do not recognize the fact that they reveal plenty of information about themselves or their affiliation and computer equipment to the providers of web pages they connect to. As a result, a lot of services offer users to access web pages unrecognized or without risk of being backtracked, respectively. This kind of anonymity is called user or client anonymity. But on the other hand, an equivalent protection for content providers does not exist, although this feature is desirable for many situations in which the identity of a publisher or content provider shall be hidden. We call this property server anonymity. We will introduce the first system with the primary target to offer anonymity for providers of information in the WWW. Beside this property, it provides also client anonymity. Based on David Chaum's idea of mixes and in relation to the context of the WWW, we explain the term 'server anonymity' motivating the system JANUS which offers both client and server anonymity.

    Directory of Open Access Journals (Sweden)

    E. A. Panidi

    2014-01-01

    Full Text Available Due to continuous improvement and cheapening of remote sensing technologies the remote sensing methods being increasingly utilized to solve problems of research, monitoring and management of the territories, natural environment, transport and society. Remote sensing data are characterized by significant volumes in general, even compared with other types of spatial data. And improving of the technologies of remote sensing data production leads to more and more significant growth of these volumes. In this context the one of most important tasks of working with remote sensing data is the development of methods for automating of the data processing and analysis, as well as ways of data and processing results storing. The cloud computing technologies and Web solutions that base on such technologies and implement data access and working with the data in the Web, are used in recent years to solve both of the problems. One of such Web-based solutions are geoportals that aggregate access ways to distributed spatial data and processing tools. In current interpretation the geoportal, as a special case of Web-GIS, should not only provide users with spatial data and metadata access but also with the processing tools that allow to solve a wide range of tasks, from displaying to analysis. However, the technologies of spatial data processing and analysis tools are the least developed and standardized at this time. The only WPS (Web Processing Service international standard specifies how to create spatial data processing Web services. This paper deals with some issues of creating Web services for the spatial data processing (geoprocessing explored by the author and his colleagues.

    1998-01-01

    NASA's New Millenium Program (NMP) has identified a variety of revolutionary technologies that will support orders of magnitude improvements in the capabilities of spacecraft missions. This program's Autonomy team has focused on science and engineering automation technologies. In doing so, it has established a clear development roadmap specifying the experiments and demonstrations required to mature these technologies. The primary developmental thrusts of this roadmap are in the areas of remote agents, PI/operator interface, planning/scheduling fault management, and smart execution architectures. Phases 1 and 2 of the ASSET Project (previously known as the WebSat project) have focused on establishing World Wide Web-based commanding and telemetry services as an advanced means of interfacing a spacecraft system with the PI and operators. Current automated capabilities include Web-based command submission, limited contact scheduling, command list generation and transfer to the ground station, spacecraft support for demonstrations experiments, data transfer from the ground station back to the ASSET system, data archiving, and Web-based telemetry distribution. Phase 2 was finished in December 1996. During January-December 1997 work was commenced on Phase 3 of the ASSET Project. Phase 3 is the subject of this report. This phase permitted SSDL and its project partners to expand the ASSET system in a variety of ways. These added capabilities included the advancement of ground station capabilities, the adaptation of spacecraft on-board software, and the expansion of capabilities of the ASSET management algorithms. Specific goals of Phase 3 were: (1) Extend Web-based goal-level commanding for both the payload PI and the spacecraft engineer; (2) Support prioritized handling of multiple PIs as well as associated payload experimenters; (3) Expand the number and types of experiments supported by the ASSET system and its associated spacecraft; (4) Implement more advanced resource

    The Internet is a widely used information resource for patients with inflammatory bowel disease, but there is variation in the quality of Web sites that have patient information regarding Crohn's disease and ulcerative colitis. The purpose of the current study is to systematically evaluate the quality of these Web sites. The top 50 Web sites appearing in Google using the terms "Crohn's disease" or "ulcerative colitis" were included in the study. Web sites were evaluated using a (a) Quality Evaluation Instrument (QEI) that awarded Web sites points (0-107) for specific information on various aspects of inflammatory bowel disease, (b) a five-point Global Quality Score (GQS), (c) two reading grade level scores, and (d) a six-point integrity score. Thirty-four Web sites met the inclusion criteria, 16 Web sites were excluded because they were portals or non-IBD oriented. The median QEI score was 57 with five Web sites scoring higher than 75 points. The median Global Quality Score was 2.0 with five Web sites achieving scores of 4 or 5. The average reading grade level score was 11.2. The median integrity score was 3.0. There is marked variation in the quality of the Web sites containing information on Crohn's disease and ulcerative colitis. Many Web sites suffered from poor quality but there were five high-scoring Web sites.

    1999-03-01

    We present here the design key concepts of WEBSLIDE, a software project whose objective is to provide a simple, cheap and efficient solution for showing slides during lessons in computer labs. In fact, WEBSLIDE allows the video monitors of several client machines (the "STUDENTS") to be synchronously updated by the actions of a particular client machine, called the "INSTRUCTOR." The system is based on the World Wide Web and the software components of WEBSLIDE mainly consists in a WWW server, browsers and small Cgi-Bill scripts. What makes WEBSLIDE particularly appealing for small educational institutions is that WEBSLIDE is built with "off the shelf" products: it does not involve using a specifically designed program but any Netscape browser, one of the most popular browsers available on the market, is sufficient. Another possible use is to use our system to implement "guided automatic tours" through several pages or Intranets internal news bulletins: the company Web server can broadcast to all employees relevant information on their browser.

  17. Do We Need to Impose More Regulation Upon the World Wide Web? -A Metasystem Analysis

    Directory of Open Access Journals (Sweden)

    John P. van Gigch

    2000-01-01

    Full Text Available Every day a new problem attributable to the World Wide Web's lack of formal structure and/or organization is made public. What arguably could be represented as one of its main strengths is rapidly turning out to be one of its most flagrant weaknesses. The intent of this article is to show the need to establish a more formal organization than presently exists over the World Wide Web. (This article will use the terms the Internet and Cyberspace interchangeably. It is proposed that this formal organization take the form of a metacontrol system--to be explained-- and rely, at least in part, for this control to self-regulate. The so-called metasystem system would be responsible for preventing some of the unanticipated situations that take place in cyberspace and that, due to the web's lack of maturity, have not been encountered heretofore. Some activities, such as the denial-of-service (DoS attacks, may well be illicit. Others, like the question of establishing a world-wide democratic board to administer the Internet's address system, are so new that there are no technical, legal or political precedents to ensure its design will succeed. What is needed is a formal, over-arching control system, i.e. a "metasystem," to arbitrate over controversies, decide on the legality of new policies and, in general, act as a metalevel controller over the activities of the virtual community called Cyberspace. The World Wide Web Consortium has emerged as a possible candidate for this role.This paper uses control theory to define both the problem and the proposed solution. Cyberspace lacks a metacontroller that can be used to resolve the many problems that arise when a new organizational configuration, such as the Internet, is created and when questions surface about the extent to which new activities interfere with individual or corporate freedoms.

    2007-01-01

    The 2- to 6-page print journal article has been the standard for 200 years, yet this format severely limits the amount of detailed information that can be conveyed. The World Wide Web provides a low-cost option for posting extended text and supplementary information. It also can enhance the experience of journal editors, reviewers, readers, and authors through added functionality (eg, online submission and peer review, postpublication critique, and e-mail notification of table of contents.) Our aim was to characterize ways that journals were using the World Wide Web in 2005 and note changes since 2003. We analyzed the Web sites of 138 high-impact print journals in 3 ways. First, we compared the print and Web versions of March 2003 and 2005 issues of 28 journals (20 of which were randomly selected from the 138) to determine how often articles were published Web only and how often print articles were augmented by Web-only supplements. Second, we examined what functions were offered by each journal Web site. Third, for journals that offered Web pages for reader commentary about each article, we analyzed the number of comments and characterized these comments. Fifty-six articles (7%) in 5 journals were Web only. Thirteen of the 28 journals had no supplementary online content. By 2005, several journals were including Web-only supplements in >20% of their papers. Supplementary methods, tables, and figures predominated. The use of supplementary material increased by 5% from 2% to 7% in the 20-journal random sample from 2003 to 2005. Web sites had similar functionality with an emphasis on linking each article to related material and e-mailing readers about activity related to each article. There was little evidence of journals using the Web to provide readers an interactive experience with the data or with each other. Seventeen of the 138 journals offered rapid-response pages. Only 18% of eligible articles had any comments after 5 months. Journal Web sites offer similar

    2001-01-01

    This editorial provides a model of how quality initiatives concerned with health information on the World Wide Web may in the future interact with each other. This vision fits into the evolving "Semantic Web" architecture - ie, the prospective that the World Wide Web may evolve from a mess of unstructured, human-readable information sources into a global knowledge base with an additional layer providing richer and more meaningful relationships between resources. One first prerequisite for forming such a "Semantic Web" or "web of trust" among the players active in quality management of health information is that these initiatives make statements about themselves and about each other in a machine-processable language. I present a concrete model on how this collaboration could look, and provide some recommendations on what the role of the World Health Organization (WHO) and other policy makers in this framework could be.

    We model the commercial World Wide Web as a directed graph that emerges as the equilibrium of a game in which utility maximizing websites purchase (advertising) in-links from each other while also setting the price of these links. In equilibrium, higher content sites tend to purchase more advertising links (mirroring the Dorfman-Steiner rule) while selling less advertising links themselves. As such, there seems to be specialization across sites in revenue models: high content sites tend to ea...

    The World Wide Web (WWW) is continuing to grow exponentially both in terms of numbers of users and numbers of web pages. There is a trend toward the increasing use of the WWW for medical educational purposes, both among physicians and patients alike. The multimedia capabilities of this evolving medium are particularly relevant to visual medical specialties such as dermatology. The origins of information consumerism on the WWW are examined, and the public health issues surrounding dermatologic information and misinformation, and how consumers navigate through the WWW are reviewed. The economic realities of medical information as a "capital good," and the impact this has on dermatologic information sources on the WWW are also discussed.Finally, strategies for guiding consumers and ourselves toward credible medical information sources on the WWW are outlined.

  4. TMFoldWeb: a web server for predicting transmembrane protein fold class.

    Science.gov (United States)

    Kozma, Dániel; Tusnády, Gábor E

    2015-09-17

    Here we present TMFoldWeb, the web server implementation of TMFoldRec, a transmembrane protein fold recognition algorithm. TMFoldRec uses statistical potentials and utilizes topology filtering and a gapless threading algorithm. It ranks template structures and selects the most likely candidates and estimates the reliability of the obtained lowest energy model. The statistical potential was developed in a maximum likelihood framework on a representative set of the PDBTM database. According to the benchmark test the performance of TMFoldRec is about 77 % in correctly predicting fold class for a given transmembrane protein sequence. An intuitive web interface has been developed for the recently published TMFoldRec algorithm. The query sequence goes through a pipeline of topology prediction and a systematic sequence to structure alignment (threading). Resulting templates are ordered by energy and reliability values and are colored according to their significance level. Besides the graphical interface, a programmatic access is available as well, via a direct interface for developers or for submitting genome-wide data sets. The TMFoldWeb web server is unique and currently the only web server that is able to predict the fold class of transmembrane proteins while assigning reliability scores for the prediction. This method is prepared for genome-wide analysis with its easy-to-use interface, informative result page and programmatic access. Considering the info-communication evolution in the last few years, the developed web server, as well as the molecule viewer, is responsive and fully compatible with the prevalent tablets and mobile devices.

  5. Comparison of student outcomes and preferences in a traditional vs. World Wide Web-based baccalaureate nursing research course.

    Leasure, A R; Davis, L; Thievon, S L

    2000-04-01

    The purpose of this project was to compare student outcomes in an undergraduate research course taught using both World Wide Web-based distance learning technology and traditional pedagogy. Reasons given for enrolling in the traditional classroom section included the perception of increased opportunity for interaction, decreased opportunity to procrastinate, immediate feedback, and more meaningful learning activities. Reasons for selecting the Web group section included cost, convenience, and flexibility. Overall, there was no significant difference in examination scores between the two groups on the three multiple-choice examinations or for the course grades (t = -.96, P = .343). Students who reported that they were self-directed and had the ability to maintain their own pace and avoid procrastination were most suited to Web-based courses. The Web-based classes can help provide opportunities for methods of communication that are not traditionally nurtured in traditional classroom settings. Secondary benefits of the World Wide Web-based course were to increase student confidence with the computer, and introduce them to skills and opportunities they would not have had in the classroom. Additionally, over time and with practice, student's writing skills improved.

    Cerdeira, Hilda; Fonda, Carlo; Cottrell, R L A

    2003-01-01

    Enabling scientists from developing countries to bridge the gap between rich and poor depends on closing another gap - the "digital divide". Now the technology exists to monitor this divide, and it reveals some alarming results. Most developing countries experience great difficulties because of adverse economic conditions and political instability, which means they lag behind in scientific and technological development. With the advent of the World Wide Web and the rapid exchange of information via the Internet, one might naively have thought that much of the gap between developed and developing nations would disappear, even if problems still persisted for those areas of science that need expensive facilities. However, access to information, peer reviewed or not, depends on having the appropriate hardware, i.e. a computer, and Internet connectivity, and there is a serious problem with access to the Internet in developing countries. Gaining access to a computer is more of a question of economics, and one that ...

    Cambil-Martín, Jacobo; Flynn, Maria; Villaverde-Gutiérrez, Carmen

    2011-09-01

    This article presents a study that evaluated the physical accessibility, readability, and usability of Spanish nursing Web sites and discusses the quality assurance issues raised, which are relevant to the wider nursing community. The Internet is recognized as an important source of health information for both nurses and the general public. Although it makes health-related information universally available, the wide variation in the overall quality of health Web sites is problematic. This raises many questions for the nursing profession: about what constitutes a good-quality Web site, about the nature of the information that nurses are finding and using to support their professional education, research, and clinical practice, and about the impact that Internet information ultimately has on health interactions and nursing care. The process of completing this small study showed that it is possible to usefully assess dimensions of Web site quality and suggested that it may be feasible to develop tools to help nurses evaluate national and international nursing Web sites. More research is needed to understand how nurses use the Internet to support their everyday professional practices, but the development and application of international Web site quality assurance tools may be important for maintaining professional nursing standards in the Internet age.

    Lehmann, Eldon D; Dewolf, Dennis K; Novotny, Christopher A; Reed, Karen; Gotwals, Robert R

    2014-01-01

    Background. AIDA is a widely available downloadable educational simulator of glucose-insulin interaction in diabetes. Methods. A web-based version of AIDA was developed that utilises a server-based architecture with HTML FORM commands to submit numerical data from a web-browser client to a remote web server. AIDA online, located on a remote server, passes the received data through Perl scripts which interactively produce 24 hr insulin and glucose simulations. Results. AIDA online allows users to modify the insulin regimen and diet of 40 different prestored "virtual diabetic patients" on the internet or create new "patients" with user-generated regimens. Multiple simulations can be run, with graphical results viewed via a standard web-browser window. To date, over 637,500 diabetes simulations have been run at AIDA online, from all over the world. Conclusions. AIDA online's functionality is similar to the downloadable AIDA program, but the mode of implementation and usage is different. An advantage to utilising a server-based application is the flexibility that can be offered. New modules can be added quickly to the online simulator. This has facilitated the development of refinements to AIDA online, which have instantaneously become available around the world, with no further local downloads or installations being required.

    2014-10-01

    Despite a recent high funding priority on technological aspects of research and a high potential impact of Web-based interventions on health, few guidelines for the development of Web-based interventions are currently available. In this article, we propose practical guidelines for development of Web-based interventions based on an empirical study and an integrative literature review. The empirical study aimed at development of a Web-based physical activity promotion program that was specifically tailored to Korean American midlife women. The literature review included a total of 202 articles that were retrieved through multiple databases. On the basis of the findings of the study and the literature review, we propose directions for development of Web-based interventions in the following steps: (1) meaningfulness and effectiveness, (2) target population, (3) theoretical basis/program theory, (4) focus and objectives, (5) components, (6) technological aspects, and (7) logistics for users. The guidelines could help promote further development of Web-based interventions at this early stage of Web-based interventions in nursing.

  20. Digital libraries and World Wide Web sites and page persistence.

    Directory of Open Access Journals (Sweden)

    Wallace Koehler

    1999-01-01

    Full Text Available Web pages and Web sites, some argue, can either be collected as elements of digital or hybrid libraries, or, as others would have it, the WWW is itself a library. We begin with the assumption that Web pages and Web sites can be collected and categorized. The paper explores the proposition that the WWW constitutes a library. We conclude that the Web is not a digital library. However, its component parts can be aggregated and included as parts of digital library collections. These, in turn, can be incorporated into "hybrid libraries." These are libraries with both traditional and digital collections. Material on the Web can be organized and managed. Native documents can be collected in situ, disseminated, distributed, catalogueed, indexed, controlled, in traditional library fashion. The Web therefore is not a library, but material for library collections is selected from the Web. That said, the Web and its component parts are dynamic. Web documents undergo two kinds of change. The first type, the type addressed in this paper, is "persistence" or the existence or disappearance of Web pages and sites, or in a word the lifecycle of Web documents. "Intermittence" is a variant of persistence, and is defined as the disappearance but reappearance of Web documents. At any given time, about five percent of Web pages are intermittent, which is to say they are gone but will return. Over time a Web collection erodes. Based on a 120-week longitudinal study of a sample of Web documents, it appears that the half-life of a Web page is somewhat less than two years and the half-life of a Web site is somewhat more than two years. That is to say, an unweeded Web document collection created two years ago would contain the same number of URLs, but only half of those URLs point to content. The second type of change Web documents experience is change in Web page or Web site content. Again based on the Web document samples, very nearly all Web pages and sites undergo some

  3. Enhancement of shear strength and ductility for reinforced concrete wide beams due to web reinforcement

    Directory of Open Access Journals (Sweden)

    M. Said

    2013-12-01

    Full Text Available The shear behavior of reinforced concrete wide beams was investigated. The experimental program consisted of nine beams of 29 MPa concrete strength tested with a shear span-depth ratio equal to 3.0. One of the tested beams had no web reinforcement as a control specimen. The flexure mode of failure was secured for all of the specimens to allow for shear mode of failure. The key parameters covered in this investigation are the effect of the existence, spacing, amount and yield stress of the vertical stirrups on the shear capacity and ductility of the tested wide beams. The study shows that the contribution of web reinforcement to the shear capacity is significant and directly proportional to the amount and spacing of the shear reinforcement. The increase in the shear capacity ranged from 32% to 132% for the range of the tested beams compared with the control beam. High grade steel was more effective in the contribution of the shear strength of wide beams. Also, test results demonstrate that the shear reinforcement significantly enhances the ductility of the wide beams. In addition, shear resistances at failure recorded in this study are compared to the analytical strengths calculated according to the current Egyptian Code and the available international codes. The current study highlights the need to include the contribution of shear reinforcement in the Egyptian Code requirements for shear capacity of wide beams.

    1997-01-01

    Purpose/Objective: The Internet offers a novel venue for providing educational material to radiation oncologists. This exhibit demonstrates its utility for providing the complete content of two past ASTRO refresher courses. Materials and Methods: The audio recording, handout and slides from the 1995 ASTRO refresher course entitled 'Radiation Therapy for Pediatric Brain Tumors; Standards of Care, Current Clinical Trials and New Directions' and the 1996 ASTRO refresher course entitled 'Internet-based communications in Radiation Oncology' were digitized and placed on an Internet World-Wide-Web site. The Web address was posted on the refresher course handout and in the meeting book ('http://goldwein 1.xrt.upenn.edu/brain95.html' and 'http://goldwein 1.xrt.upenn.edu/astro96/'). The computer distributing this material is an Intel-based 486 DEC50 personal computer with a 50 Mhz processor running Windows NT 3.51 workstation. Software utilized to distribute the material is in the public domain and includes EWMAC's 'httpd', and Progressive Network's 'RealAudio Server' and 'Encoder'. The University's dedicated Internet connection is used to 'serve' this material. Results: The two approximately 100 minute lectures have been encoded into several 'RealAudio' files totaling 10 Megabytes in size. These files are accessible with moderate to excellent quality and speed utilizing as little as a 14.4k modem connection to the Internet. Use of 'streaming' technology provides a means for playing the audio files over the Internet after downloading only a small portion of the files. The time required to digitize the material has been approximately 40 hours, with most time related to digitizing slides from a Powerpoint presentation. Not all slides have been digitized as of this time. To date, approximately 400 accesses to this resource have been logged on the system. Seven electronic comment forms for the second course have all rated it as 'superior'. Pitfalls include the difficulty

    2001-05-07

    With the exponential growth of information on the World Wide Web there is great demand for developing efficient and effective methods for organizing and retrieving the information available. Document clustering plays an important role in information retrieval and taxonomy management for the World Wide Web and remains an interesting and challenging problem in the field of web computing. In this paper we consider document clustering methods exploring textual information hyperlink structure and co-citation relations. In particular we apply the normalized cut clustering method developed in computer vision to the task of hyperdocument clustering. We also explore some theoretical connections of the normalized-cut method to K-means method. We then experiment with normalized-cut method in the context of clustering query result sets for web search engines.

    The ability to remotely acquire information and even to control appliances/devices at fingertips over the Internet is becoming desirable to the general public as well as professionals. In this paper, a web-based remote electric load supervision and control (WBRELSAC) system with automatic meter reading and demand control via programmable logic controllers (PLCs) is presented. For both utilities and industrial/commercial customers, the electric load supervision and control (ELSAC) system is a critical function to their load management. However, most high voltage customers do not have enough capital to build a regular-scale supervisory control and data acquisition system as the one for utilities. Therefore, we adopt the industrial-widely-used PLCs in WBRELSAC. In order to make a non-web-based PLC become web-controllable, we develop a graphical-control interface and utilize Internet techniques to implement our system. Based on the performance test conducted under the Laboratory environment, the proposed WBRELSAC architecture is cost-effective and suitable for industrial applications. (author)

  13. Women, pharmacy and the World Wide Web: could they be the answer to the obesity epidemic?

    The objective of this article is to explore how giving women access to evidence-based information in weight management through pharmacies, and by utilising the World Wide Web, is a much needed step towards dealing with the obesity crisis. Women's needs should be considered when developing evidence-based information on weight. Excess weight places them at high risk of diabetes and cardiovascular disease, infertility and complications following pregnancy and giving birth. Women are also an important population group because they influence decision-making around meal choices for their families and are the biggest consumers of weight-loss products, many of which can be purchased in pharmacies. Pharmacies are readily accessible primary healthcare locations and given the pharmacist's expertise in being able to recognise underlying causes of obesity (e.g. medications, certain disease states), pharmacies are an ideal location to provide women with evidence-based information on all facets of weight management. Considering the exponential rise in the use of the World Wide Web, this information could be delivered as an online educational resource supported by other flexible formats. The time has come for the development of an online, evidence-based educational resource on weight management, which is combined with other flexible formats and targeted at women in general and according to different phases of their lives (pregnancy, post-partum, menopause). By empowering women with this knowledge it will allow them and their families to take better control of their health and wellbeing, and it may just be the much needed answer to complement already existing resources to help curb the obesity epidemic. © 2013 Royal Pharmaceutical Society.

  14. Obtaining Streamflow Statistics for Massachusetts Streams on the World Wide Web

    2000-01-01

    A World Wide Web application has been developed to make it easy to obtain streamflow statistics for user-selected locations on Massachusetts streams. The Web application, named STREAMSTATS (available at http://water.usgs.gov/osw/streamstats/massachusetts.html ), can provide peak-flow frequency, low-flow frequency, and flow-duration statistics for most streams in Massachusetts. These statistics describe the magnitude (how much), frequency (how often), and duration (how long) of flow in a stream. The U.S. Geological Survey (USGS) has published streamflow statistics, such as the 100-year peak flow, the 7-day, 10-year low flow, and flow-duration statistics, for its data-collection stations in numerous reports. Federal, State, and local agencies need these statistics to plan and manage use of water resources and to regulate activities in and around streams. Engineering and environmental consulting firms, utilities, industry, and others use the statistics to design and operate water-supply systems, hydropower facilities, industrial facilities, wastewater treatment facilities, and roads, bridges, and other structures. Until now, streamflow statistics for data-collection stations have often been difficult to obtain because they are scattered among many reports, some of which are not readily available to the public. In addition, streamflow statistics are often needed for locations where no data are available. STREAMSTATS helps solve these problems. STREAMSTATS was developed jointly by the USGS and MassGIS, the State Geographic Information Systems (GIS) agency, in cooperation with the Massachusetts Departments of Environmental Management and Environmental Protection. The application consists of three major components: (1) a user interface that displays maps and allows users to select stream locations for which they want streamflow statistics (fig. 1), (2) a data base of previously published streamflow statistics and descriptive information for 725 USGS data

  15. Educational Applications on the World Wide Web: An Example Using Amphion

    1998-01-01

    There is a great deal of excitement about using the internet and the World Wide Web in education. There are such exciting possibilities and there is a wealth and variety of material up on the web. There are however many problems, problems of access and resources, problems of quality -- for every excellent resource there are many poor ones, and there are insufficiently explored problems of teacher training and motivation. For example, Wiesenmayer and Meadows report on a study of 347 West Virginia science teachers. These teachers were enrolled in a week-long summer workshop to introduce them to the internet and its educational potential. The teachers were asked to review science sites as to overall quality and then about their usefulness in their own classrooms. The teachers were enthusiastic about the web, and gave two-thirds of the sites high ratings, and essentially all the rest average ratings. But alarmingly, over 80% of these sites were viewed as having no direct applicability in the teacher's own classroom. This summer I was assigned to work on the Amphion project in the Automated Software Engineering Group under the leadership of Michael Lowry. I wished to find educational applications of the Amphion system, which in its current implementation can be used to create fortran programs and animations using the SPICE libraries created by the NAIF group at JPL. I wished to find an application which provided real added educational value, which was in line with educational curriculum standards and which would serve a documented need of the educational community. The application selected was teaching about the causes of the seasons -- at the approximately the fourth, fifth, sixth grade level. This topic was chosen because it is in line with national curriculum standards. The fourth, fifth, sixth grade level was selected to coincide with the grade level served by the Ames Aerospace Encounter, which services 10,000 children a year on field trips. The hope is that

    2012-01-01

    Traditionally, surgical education has been confined to operating and lecture theaters. Access to the World Wide Web and services, such as YouTube and iTunes has expanded enormously. Each week throughout Ireland, nonconsultant hospital doctors work hard to create presentations for surgical teaching. Once presented, these valuable presentations are often never used again. We aimed to compile surgical presentations online and establish a new online surgical education tool. We also sought to measure the effect of this educational tool on surgical presentation quality. Surgical presentations from Cork University Hospital and Beaumont Hospital presented between January 2010 and April 2011 were uploaded to http://www.pilgrimshospital.com/presentations. A YouTube channel and iTunes application were created. Web site hits were monitored. Quality of presentations was assessed by 4 independent senior surgical judges using a validated PowerPoint assessment form. Judges were randomly given 6 presentations; 3 presentations were pre-web site setup and 3 were post-web site setup. Once uploading commenced, presenters were informed. A total of 89 presentations have been uploaded to date. This includes 55 cases, 17 journal club, and 17 short bullet presentations. This has been associated with 46,037 web site page views. Establishment of the web site was associated with a significant improvement in the quality of presentations. Mean scores for pre- and post-web site group were 6.2 vs 7.7 out of 9 respectively, p = 0.037. This novel educational tool provides a unique method to enable surgical education become more accessible to trainees, while also improving the overall quality of surgical teaching PowerPoint presentations.

    2008-12-15

    To determine the validity of the information on the World Wide Web concerning veterinary anesthesia in dogs and to determine the methods dog owners use to obtain that information. Web-based search and client survey. 73 Web sites and 92 clients. Web sites were scored on a 5-point scale for completeness and accuracy of information about veterinary anesthesia by 3 board-certified anesthesiologists. A search for anesthetic information regarding 49 specific breeds of dogs was also performed. A survey was distributed to the clients who visited the University of Georgia Veterinary Teaching Hospital during a 4-month period to solicit data about sources used by clients to obtain veterinary medical information and the manner in which information obtained from Web sites was used. The general search identified 73 Web sites that included information on veterinary anesthesia; these sites received a mean score of 3.4 for accuracy and 2.5 for completeness. Of 178 Web sites identified through the breed-specific search, 57 (32%) indicated that a particular breed was sensitive to anesthesia. Of 83 usable, completed surveys, 72 (87%) indicated the client used the Web for veterinary medical information. Fifteen clients (18%) indicated they believed their animal was sensitive to anesthesia because of its breed. Information available on the internet regarding anesthesia in dogs is generally not complete and may be misleading with respect to risks to specific breeds. Consequently, veterinarians should appropriately educate clients regarding anesthetic risk to their particular dog.

    Literacy is a national and international problem. Studies have shown the readability of adult and pediatric patient education materials to be too high for average adults. Materials should be written at the 8th-grade level or lower. To determine the general readability of pediatric patient education materials designed for adults on the World Wide Web (WWW). GeneralPediatrics.com (http://www.generalpediatrics.com) is a digital library serving the medical information needs of pediatric health care providers, patients, and families. Documents from 100 different authoritative Web sites designed for laypersons were evaluated using a built-in computer software readability formula (Flesch Reading Ease and Flesch-Kincaid reading levels) and hand calculation methods (Fry Formula and SMOG methods). Analysis of variance and paired t tests determined significance. Eighty-nine documents constituted the final sample; they covered a wide spectrum of pediatric topics. The overall Flesch Reading Ease score was 57.0. The overall mean Fry Formula was 12.0 (12th grade, 0 months of schooling) and SMOG was 12.2. The overall Flesch-Kincaid grade level was significantly lower (Peducation materials on the WWW are not written at an appropriate reading level for the average adult. We propose that a practical reading level and how it was determined be included on all patient education materials on the WWW for general guidance in material selection. We discuss suggestions for improved readability of patient education materials.

    Full Text Available Using the Research Development (R&D methodology, the study aimed to develop and validate WebQuests which can be used in literature subjects, particularly in the tertiary level to address the need of literature teachers for pedagogy in the teaching of epic s. The development of the Web Quests was anchored on the Theory of Constructivism. Two groups of experts validated the Web Quests – the literature experts and the ICT experts. The Content Validation Checklist, used by the literature experts, was utilized t o evaluate the content of the Web Quests. Meanwhile, the Rubric for Evaluating Web Quests, used by the ICT experts, was utilized to evaluate the design characteristics of the Web Quests. Computed weighted means using range interval of point scores were emp loyed to treat the data gathered from the evaluation conducted by both group of experts. The Web Quests developed contain five major parts which include: 1 introduction; 2 task; 3 process; 4 evaluation; and 5 conclusion. Based on the findings, the con tent of the Web Quests developed are valid in terms of objectives, activities and instructional characteristics. Likewise, the design characteristics of the Web Quests are excellent in terms of introductions, tasks, processes, resources, evaluations, concl usions and overall designs. Thus, the Web Quests developed are acceptable and can be utilized as instructional materials by literature teachers in the teaching of epics.

    On January 14, 1993, NASA Langley Research Center (LaRC) made approximately 130 formal, 'unclassified, unlimited' technical reports available via the anonymous FTP Langley Technical Report Server (LTRS). LaRC was the first organization to provide a significant number of aerospace technical reports for open electronic dissemination. LTRS has been successful in its first 18 months of operation, with over 11,000 reports distributed and has helped lay the foundation for electronic document distribution for NASA. The availability of World Wide Web (WWW) technology has revolutionized the Internet-based information community. This paper describes the transition of LTRS from a centralized FTP site to a distributed data model using the WWW, and suggests how the general model for LTRS can be applied to other similar systems.

    This study details my viewpoint on the experiences, lessons, and assessments of conducting a national study on care-seeking behavior for heart attack in the United States utilizing the World Wide Web. The Yale Heart Study (YHS) was funded by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH). Grounded on two prior studies, the YHS combined a Web-based interview survey instrument; ads placed on the Internet; flyers and posters in public libraries, senior centers, and rehabilitation centers; information on chat rooms; a viral marketing strategy; and print ads to attract potential participants to share their heart attack experiences. Along the way, the grant was transferred from Ohio State University (OSU) to Yale University, and significant administrative, information technology, and personnel challenges ensued that materially delayed the study's execution. Overall, the use of the Internet to collect data on care-seeking behavior is very time consuming and emergent. The cost of using the Web was approximately 31% less expensive than that of face-to-face interviews. However, the quality of the data may have suffered because of the absence of some data compared with interviewing participants. Yet the representativeness of the 1154 usable surveys appears good, with the exception of a dearth of African American participants. ©Angelo A Alonzo.

    Computerizing paper-based CPG and then executing them can provide evidence-informed decision support to physicians at the point of care. Semantic web technologies especially web ontology language (OWL) ontologies have been profusely used to represent computerized CPG. Using semantic web reasoning capabilities to execute OWL-based computerized CPG unties them from a specific custom-built CPG execution engine and increases their shareability as any OWL reasoner and triple store can be utilized for CPG execution. However, existing semantic web reasoning-based CPG execution engines suffer from lack of ability to execute CPG with high levels of expressivity, high cognitive load of computerization of paper-based CPG and updating their computerized versions. In order to address these limitations, we have developed three CPG execution engines based on OWL 1 DL, OWL 2 DL and OWL 2 DL + semantic web rule language (SWRL). OWL 1 DL serves as the base execution engine capable of executing a wide range of CPG constructs, however for executing highly complex CPG the OWL 2 DL and OWL 2 DL + SWRL offer additional executional capabilities. We evaluated the technical performance and medical correctness of our execution engines using a range of CPG. Technical evaluations show the efficiency of our CPG execution engines in terms of CPU time and validity of the generated recommendation in comparison to existing CPG execution engines. Medical evaluations by domain experts show the validity of the CPG-mediated therapy plans in terms of relevance, safety, and ordering for a wide range of patient scenarios.

    Full Text Available Some content in multimedia resources can depict or evoke certain emotions in users. The aim of Emotional Information Retrieval (EmIR and of our research is to identify knowledge about emotional-laden documents and to use these findings in a new kind of World Wide Web information service that allows users to search and browse by emotion. Our prototype, called Media EMOtion SEarch (MEMOSE, is largely based on the results of research regarding emotive music pieces, images and videos. In order to index both evoked and depicted emotions in these three media types and to make them searchable, we work with a controlled vocabulary, slide controls to adjust the emotions’ intensities, and broad folksonomies to identify and separate the correct resource-specific emotions. This separation of so-called power tags is based on a tag distribution which follows either an inverse power law (only one emotion was recognized or an inverse-logistical shape (two or three emotions were recognized. Both distributions are well known in information science. MEMOSE consists of a tool for tagging basic emotions with the help of slide controls, a processing device to separate power tags, a retrieval component consisting of a search interface (for any topic in combination with one or more emotions and a results screen. The latter shows two separately ranked lists of items for each media type (depicted and felt emotions, displaying thumbnails of resources, ranked by the mean values of intensity. In the evaluation of the MEMOSE prototype, study participants described our EmIR system as an enjoyable Web 2.0 service.

    Directory of Open Access Journals (Sweden)

    Stephen Corich

    Full Text Available This paper revisits the debate concerning which development environment should be used to teach server-side Web Application Development courses to undergraduate students. In 2002, following an industry-based survey of Web developers, a decision was made to adopt an open source platform consisting of PHP and MySQL rather than a Microsoft platform utilising Access and Active Server Pages. Since that date there have been a number of significant changes within the computing industry that suggest that perhaps it is appropriate to revisit the original decision. This paper investigates expert opinion by reviewing current literature regarding web development environments, it looks at the results of a survey of web development companies and it examines the current employment trends in the web development area. The paper concludes by examining the impact of making a decision to change the development environment used to teach Web Application Development to a third year computing degree class and describes the impact on course delivery that the change has brought about.

    2009-04-01

    Increasingly, the use of web database portfolio systems is noted in medical and health education, and for continuing professional development (CPD). However, the functions of existing systems are not always aligned with the corresponding pedagogy and hence reflection is often lost. This paper presents the development of a tailored web database portfolio system with Picture Archiving and Communication System (PACS) connectivity, which is based on the portfolio pedagogy. Following a pre-determined portfolio framework, a system model with the components of web, database and mail servers, server side scripts, and a Query/Retrieve (Q/R) broker for conversion between Hypertext Transfer Protocol (HTTP) requests and Q/R service class of Digital Imaging and Communication in Medicine (DICOM) standard, is proposed. The system was piloted with seventy-seven volunteers. A tailored web database portfolio system (http://radep.hti.polyu.edu.hk) was developed. Technological arrangements for reinforcing portfolio pedagogy include popup windows (reminders) with guidelines and probing questions of 'collect', 'select' and 'reflect' on evidence of development/experience, limitation in the number of files (evidence) to be uploaded, the 'Evidence Insertion' functionality to link the individual uploaded artifacts with reflective writing, capability to accommodate diversity of contents and convenient interfaces for reviewing portfolios and communication. Evidence to date suggests the system supports users to build their portfolios with sound hypertext reflection under a facilitator's guidance, and with reviewers to monitor students' progress providing feedback and comments online in a programme-wide situation.

    Koo, M M; Rohan, T E

    2000-11-01

    The recent availability of World Wide Web-based directories has opened up a new approach for tracing subjects in epidemiologic studies. The completeness of two World Wide Web-based directories (Canada411 and InfoSpace Canada) for subject tracing was evaluated by using a randomized crossover design for 346 adults randomly selected from respondents in an ongoing cohort study. About half (56.4%) of the subjects were successfully located by using either Canada411 or InfoSpace. Of the 43.6% of the subjects who could not be located using either directory, the majority (73.5%) were female. Overall, there was no clear advantage of one directory over the other. Although Canada411 could find significantly more subjects than InfoSpace, the number of potential matches returned by Canada411 was also higher, which meant that a longer list of potential matches had to be examined before a true match could be found. One strategy to minimize the number of potential matches per true match is to first search by InfoSpace with the last name and first name, then by Canada411 with the last name and first name, and finally by InfoSpace with the last name and first initial. Internet-based searches represent a potentially useful approach to tracing subjects in epidemiologic studies.

  1. Secure Web Developers Needed!

    CERN Multimedia

    2012-01-01

    You’re about to launch a new website? Cool!! With today’s web programming languages like PHP, Java, Python or Perl, complex websites can be created, easily fulfilling all your use cases. But hold on. Did you ever think about how easily this can be abused? Attackers today are already using automatic tools which can quickly and easily find and exploit vulnerable web applications.   Web applications often suffer from security vulnerabilities, i.e. design flaws or programming bugs that remained undetected during the whole software development cycle. In production these vulnerabilities become security holes, providing an opportunity for exploitation, and can pose immense security risks (and there is no reason to believe that CERN is immune to this). The costs associated with eliminating these bugs could be loosely described by the "1:10:100 rule", i.e. the relative costs for fixing are 1:10:100 for fixing them in the programming:testing:production phases. Thus, the...

  2. Enabling web users and developers to script accessibility with Accessmonkey.

    2009-07-01

    Efficient web access remains elusive for blind computer users. Previous efforts to improve web accessibility have focused on developer awareness, automated improvement, and legislation, but these approaches have left remaining concerns. First, while many tools can help produce accessible content, most are difficult to integrate into existing developer workflows and rarely offer specific suggestions that developers can implement. Second, tools that automatically improve web content for users generally solve specific problems and are difficult to combine and use on a diversity of existing assistive technology. Finally, although blind web users have proven adept at overcoming the shortcomings of the web and existing tools, they have been only marginally involved in improving the accessibility of their own web experience. In a step toward addressing these concerns, we have developed Accessmonkey, a common scripting framework that web users, web developers and web researchers can use to collaboratively improve accessibility. This framework advances the idea that Javascript and dynamic web content can be used to improve inaccessible content instead of being a cause of it. Using Accessmonkey, web users and developers on different platforms and with potentially different goals can collaboratively make the web more accessible. In this article, we first present the design of the Accessmonkey framework and offer several example scripts that demonstrate the utility of our approach. We conclude by discussing possible future extensions that will provide easy access to scripts as users browse the web and enable non-technical blind users to independently create and share improvements.

  3. Capataz: a framework for distributing algorithms via the World Wide Web

    2015-08-01

    Full Text Available In recent years, some scientists have embraced the distributed computing paradigm. As experiments and simulations demand ever more computing power, coordinating the efforts of many different processors is often the only reasonable resort. We developed an open-source distributed computing framework based on web technologies, and named it Capataz. Acting as an HTTP server, web browsers running on many different devices can connect to it to contribute in the execution of distributed algorithms written in Javascript. Capataz takes advantage of architectures with many cores using web workers. This paper presents an improvement in Capataz´ usability and why it was needed. In previous experiments the total time of distributed algorithms proved to be susceptible to changes in the execution time of the jobs. The system now adapts by bundling jobs together if they are too simple. The computational experiment to test the solution is a brute force estimation of pi. The benchmark results show that by bundling jobs, the overall perfomance is greatly increased.

    Web services are emerging as an interesting mechanism for a wide range of grid services, particularly those focused upon information services and control. When coupled with efficient data transfer services, they provide a powerful mechanism for building a flexible, open, extensible data grid for science applications. In this paper we present our prototype work on a Java Storage Resource Manager (JSRM) web service and a Java Reliable File Transfer (JRFT) web service. A java client (Grid File Manager) on top of JSRM and is developed to demonstrate the capabilities of these web services. The purpose of this work is to show the extent to which SOAP based web services are an appropriate direction for building a grid-wide data management system, and eventually grid-based portals

  5. Migrating the facility profile information management system into the world wide web

    Energy Technology Data Exchange (ETDEWEB)

    1994-09-01

    The Department of Energy - Office of Special Projects and Argonne National Laboratory (ANL), along with the Department of Energy - office of Scientific and Technical Information have previously designed and implemented the Environment, Safety and Health Facility Profile Information Management System (FPIMS) to facilitate greater efficiency in searching, analyzing and disseminating information found within environment, safety and health oversight documents. This information retrieval based system serves as a central repository for full-text electronic oversight documents, as well as a management planning and decision making tool that can assist in trend and root cause analyses. Continuous improvement of environment, safety and health programs are currently aided through this personal computer-based system by providing a means for the open communication of lessons learned across the department. Overall benefits have included reductions in costs and improvements in past information management capabilities. Access to the FPIMS has been possible historically through a headquarters-based local area network equipped with modems. Continued demand for greater accessibility of the system by remote DOE field offices and sites, in conjunction with the Secretary of Energy` s call for greater public accessibility to Department of Energy (DOE) information resources, has been the impetus to expand access through the use of Internet technologies. Therefore, the following paper will discuss reasons for migrating the FPIMS system into the World Wide Web (Web), various lessons learned from the FPIMS migration effort, as well as future plans for enhancing the Web-based FPIMS.

    2010-01-01

    A software program that searches and browses mission data emulates a Web browser, containing standard meta - phors for Web browsing. By taking advantage of back-end URLs, users may save and share search states. Also, since a Web interface is familiar to users, training time is reduced. Familiar back and forward buttons move through a local search history. A refresh/reload button regenerates a query, and loads in any new data. URLs can be constructed to save search results. Adding context to the current search is also handled through a familiar Web metaphor. The query is constructed by clicking on hyperlinks that represent new components to the search query. The selection of a link appears to the user as a page change; the choice of links changes to represent the updated search and the results are filtered by the new criteria. Selecting a navigation link changes the current query and also the URL that is associated with it. The back button can be used to return to the previous search state. This software is part of the MSLICE release, which was written in Java. It will run on any current Windows, Macintosh, or Linux system.

    Full Text Available In the previous report in this series, Web browser loading times were measured in 12 Asian countries, and were found to be up to four times slower than commonly prescribed as acceptable. Failure of webpages to load at all was frequent. The current follow-up study compares these loading times with the complexity of the Internet routes linking the Web users and the Web servers hosting them. The study was conducted in the same 12 Asian countries, with the assistance of members of the International Development Research Centre’s PANdora distance education research network. The data were generated by network members in Bhutan, Cambodia, India, Indonesia, Laos, Mongolia, the Philippines, Sri Lanka, Pakistan, Singapore, Thailand, and Vietnam. Additional data for the follow-up study were collected in China. Using a ‘traceroute’ routine, the study indicates that webpage loading time is linked to the complexity of the Internet routes between Web users and the host server. It is indicated that distance educators can apply such information in the design of improved online delivery and mirror sites, notably in areas of the developing world which currently lack an effective infrastructure for online education.

    Peltz, J E; Haskell, W L; Matheson, G O

    1999-12-01

    Mandatory preparticipation examinations (PPE) are labor intensive, offer little routine health maintenance and are poor predictors of future injury or illness. Our objective was to develop a new PPE for the Stanford University varsity athletes that improved both quality of primary and preventive care and physician time efficiency. This PPE is based on the annual submission, by each athlete, of a comprehensive medical history questionnaire that is then summarized in a two-page report for the examining physician. The questionnaire was developed through a search of MEDLINE from 1966 to 1997, review of PPE from 11 other institutions, and discussion with two experts from each of seven main content areas: medical and musculoskeletal history, eating, menstrual and sleep disorders, stress and health risk behaviors. Content validity was assessed by 10 sports medicine physicians and four epidemiologists. It was then programmed for the World Wide Web (http:// www.stanford.edu/dept/sportsmed/). The questionnaire demonstrated a 97 +/- 2% sensitivity in detecting positive responses requiring physician attention. Sixteen physicians administered the 1997/98 PPE; using the summary reports, 15 found improvement in their ability to provide overall medical care including health issues beyond clearance; 13 noted a decrease in time needed for each athlete exam. Over 90% of athletes who used the web site found it "easy" or "moderately easy" to access and complete. Initial assessment of this new PPE format shows good athlete compliance, improved exam efficiency and a strong increase in subjective physician satisfaction with the quality of screening and medical care provided. The data indicate a need for improvement of routine health maintenance in this population. The database offers opportunities to study trends, risk factors, and results of interventions.

    This article describes the process of establishing a Web site as part of a collaborative project using visual art to promote breast health education. The need for a more "user-friendly" comprehensive breast health Web site that is aesthetically rewarding was identified after an analysis of current Web sites available through the World Wide Web. Two predetermined sets of criteria, accountability and aesthetics, were used to analyze these sites and to generate ideas for creating a breast health education Web site using visual art. Results of the analyses conducted are included as well as the factors to consider for incorporating into a Web site. The process specified is thorough and can be applied to establish a Web site that is aesthetically rewarding and informative for a variety of educational purposes.

  12. Development of a laboratory niche Web site.

    Dimenstein, Izak B; Dimenstein, Simon I

    2013-10-01

    This technical note presents the development of a methodological laboratory niche Web site. The "Grossing Technology in Surgical Pathology" (www.grossing-technology.com) Web site is used as an example. Although common steps in creation of most Web sites are followed, there are particular requirements for structuring the template's menu on methodological laboratory Web sites. The "nested doll principle," in which one object is placed inside another, most adequately describes the methodological approach to laboratory Web site design. Fragmentation in presenting the Web site's material highlights the discrete parts of the laboratory procedure. An optimally minimal triad of components can be recommended for the creation of a laboratory niche Web site: a main set of media, a blog, and an ancillary component (host, contact, and links). The inclusion of a blog makes the Web site a dynamic forum for professional communication. By forming links and portals, cloud computing opens opportunities for connecting a niche Web site with other Web sites and professional organizations. As an additional source of information exchange, methodological laboratory niche Web sites are destined to parallel both traditional and new forms, such as books, journals, seminars, webinars, and internal educational materials.

    In order for humans and electronics to fully and safely operate in the space environment, codes like HZETRN (High Charge and Energy Transport) must be included in any designer's toolbox for design evaluation with respect to radiation damage. Currently, spacecraft designers do not have easy access to accurate radiation codes like HZETRN to evaluate their design for radiation effects on humans and electronics. Today, the World Wide Web is sophisticated enough to support the entire HZETRN code and all of the associated pre and post processing tools. This package is called SIREST (Space Ionizing Radiation Effects and Shielding Tools). There are many advantages to SIREST. The most important advantage is the instant update capability of the web. Another major advantage is the modularity that the web imposes on the code. Right now, the major disadvantage of SIREST will be its modularity inside the designer's system. This mostly comes from the fact that a consistent interface between the designer and the computer system to evaluate the design is incomplete. This, however, is to be solved in the Intelligent Synthesis Environment (ISE) program currently being funded by NASA.

    In siting a repository for high level radioactive wastes (HLW), it is essential for consensus building intelligibly and visually present why and how the area is selected as a suitable site. However 'information asymmetry' exists especially between society and an implementation body because various types of investigation, analysis and assessment are implemented in site characterization on the basis of a wide variety of advanced science and technology. Communication between experts (e.g. surveyors and modelers) is also important for efficient and reliable site investigation/ characterization. The Web-based Site Investigation Flow Diagram (SIFD) has been developed as a tool for information sharing among stake holders and society-jointed decision making. To test applicability of the SIFD, virtual site characterization ('dry run') is performed using the existing site investigation data. It is concluded that the web-based SIFD enhance traceability and transparency of the site investigation/ characterization, and therefore it would be a powerful communication tool among experts for efficient and reliable site investigation/characterization and among stake holders for consensus building

    2008-01-01

    Web 2.0 is a term used to describe recent developments on the World Wide Web. The term is often used to describe the increased use of the web for user-generated content, collaboration, and social networking. However, Web 2.0 is a weakly defined concept, and it is unclear exactly what kind...... of technologies it covers. The objective of the paper is to develop a typology that can be used to categorize Web 2.0 technologies. Further, the paper will discuss which of these technologies are unique to Web 2.0. Often, Web 2.0 is described by way of different kinds of software; for instance, blogs, wikis......, podcasts, RSS, and social networking sites. The problem with this type of description is that it fails to distinguish between different types or categories of technologies. As an alternative, the typology developed in the paper distinguishes between technologies on basis of, how - and in which contexts...

    2013-04-01

    Health care practitioners have increasingly used the Internet to obtain health and medication information. The vast number of Internet Web sites providing such information and concerns with their reliability makes it essential for users to carefully select and evaluate Web sites prior to use. To this end, this article reviews the general principles to consider in this process. Moreover, as cost may limit access to subscription-based health and medication information resources with established reputability, freely accessible online resources that may serve as an invaluable addition to one's reference collection are highlighted. These include government- and organization-sponsored resources (eg, US Food and Drug Administration Web site and the American Society of Health-System Pharmacists' Drug Shortage Resource Center Web site, respectively) as well as commercial Web sites (eg, Medscape, Google Scholar). Familiarity with such online resources can assist health care professionals in their ability to efficiently navigate the Web and may potentially expedite the information gathering and decision-making process, thereby improving patient care.

  4. Ten years for the public Web

    2003-01-01

    Ten years ago, CERN issued a statement declaring that a little known piece of software called the World Wide Web was in the public domain. Nowadays, the Web is an indispensable part of modern communications. The idea for the Web goes back to March 1989 when CERN Computer scientist Tim Berners-Lee wrote a proposal for a 'Distributed Information Management System' for the high-energy physics community. The Web was originaly conceived and developed to meet the demand for information sharing between scientists working all over the world. There were many obstacles in the 1980s to the effective exchange of information. There was, for example a great variety of computer and network systems, with hardly any common features. The main purpose of the web was to allow scientists to access information from any source in a consistent and simple way. By Christmas 1990, Berners-Lee's idea had become the World Wide Web, with its first server and browser running at CERN. Through 1991, the Web spread to other particle physics ...

    There are many analysis codes that analyze various aspects of plasma physics. However, most of them are FORTRAN programs that are written to be run in supercomputers. On the other hand, many scientists use GUI (graphical user interface)-based operating systems. For those who are not familiar with supercomputers, it is a difficult task to run analysis codes in supercomputers, and they often hesitate to use these programs to substantiate their ideas. Furthermore, these analysis codes are written for personal use, and the programmers do not expect these programs to be run by other users. In order to make these programs to be widely used by many users, the authors developed user-friendly interfaces using a Web interface. Since the Web browser is one of the most common applications, it is useful for both the users and developers. In order to realize interactive Web interface, AJAX technique is widely used, and the authors also adopted AJAX. To build such an AJAX based Web system, Ruby on Rails plays an important role in this system. Since this application framework, which is written in Ruby, abstracts the Web interfaces necessary to implement AJAX and database functions, it enables the programmers to efficiently develop the Web-based application. In this paper, the authors will introduce the system and demonstrate the usefulness of this approach.

    Eysenbach, Gunther; Powell, John; Kuss, Oliver; Sa, Eun-Ryoung

    The quality of consumer health information on the World Wide Web is an important issue for medicine, but to date no systematic and comprehensive synthesis of the methods and evidence has been performed. To establish a methodological framework on how quality on the Web is evaluated in practice, to determine the heterogeneity of the results and conclusions, and to compare the methodological rigor of these studies, to determine to what extent the conclusions depend on the methodology used, and to suggest future directions for research. We searched MEDLINE and PREMEDLINE (1966 through September 2001), Science Citation Index (1997 through September 2001), Social Sciences Citation Index (1997 through September 2001), Arts and Humanities Citation Index (1997 through September 2001), LISA (1969 through July 2001), CINAHL (1982 through July 2001), PsychINFO (1988 through September 2001), EMBASE (1988 through June 2001), and SIGLE (1980 through June 2001). We also conducted hand searches, general Internet searches, and a personal bibliographic database search. We included published and unpublished empirical studies in any language in which investigators searched the Web systematically for specific health information, evaluated the quality of Web sites or pages, and reported quantitative results. We screened 7830 citations and retrieved 170 potentially eligible full articles. A total of 79 distinct studies met the inclusion criteria, evaluating 5941 health Web sites and 1329 Web pages, and reporting 408 evaluation results for 86 different quality criteria. Two reviewers independently extracted study characteristics, medical domains, search strategies used, methods and criteria of quality assessment, results (percentage of sites or pages rated as inadequate pertaining to a quality criterion), and quality and rigor of study methods and reporting. Most frequently used quality criteria used include accuracy, completeness, readability, design, disclosures, and references provided

    Long, L. Rodney; Goh, Gin-Hua; Neve, Leif; Thoma, George R.

    1997-10-01

    Research engineers at the National Library of Medicine are building a prototype system for the delivery of multimedia biomedical information on the World Wide Web. This paper discuses the architecture and design considerations for the system, which will be used initially to make images and text from the third National Health and Nutrition Examination Survey (NHANES) publicly available. We categorized our analysis as follows: (1) fundamental software tools: we analyzed trade-offs among use of conventional HTML/CGI, X Window Broadway, and Java; (2) image delivery: we examined the use of unconventional TCP transmission methods; (3) database manager and database design: we discuss the capabilities and planned use of the Informix object-relational database manager and the planned schema for the HNANES database; (4) storage requirements for our Sun server; (5) user interface considerations; (6) the compatibility of the system with other standard research and analysis tools; (7) image display: we discuss considerations for consistent image display for end users. Finally, we discuss the scalability of the system in terms of incorporating larger or more databases of similar data, and the extendibility of the system for supporting content-based retrieval of biomedical images. The system prototype is called the Web-based Medical Information Retrieval System. An early version was built as a Java applet and tested on Unix, PC, and Macintosh platforms. This prototype used the MiniSQL database manager to do text queries on a small database of records of participants in the second NHANES survey. The full records and associated x-ray images were retrievable and displayable on a standard Web browser. A second version has now been built, also a Java applet, using the MySQL database manager.

    During my 2015 internship at Stennis Space Center (SSC) I supported the development of a web based tool to enable user interaction with a low-cost environmental monitoring buoy called the DRIFTER. DRIFTERs are designed by SSC's Applied Science and Technology Projects branch and are used to measure parameters such as water temperature and salinity. Data collected by the buoys help verify measurements by NASA satellites, which contributes to NASA's mission to advance understanding of the Earth by developing technologies to improve the quality of life on or home planet. My main objective during this internship was to support the development of the DRIFTER by writing web-based software that allows the public to view and access data collected by the buoys. In addition, this software would enable DRIFTER owners to configure and control the devices.

    The paper describes a methodology for designing a web site for human factor engineers that is applicable for designing a web site for a group of people. Many web pages on the World Wide Web are not organized in a format that allows a user to efficiently find information. Often the information and hypertext links on web pages are not organized into intuitive groups. Intuition implies that a person is able to use their knowledge of a paradigm to solve a problem. Intuitive groups are categories that allow web page users to find information by using their intuition or mental models of categories. In order to improve the human factors engineers efficiency for finding information on the World Wide Web, research was performed to develop a web site that serves as a tool for finding information effectively. The paper describes a methodology for designing a web site for a group of people who perform similar task in an organization.

  13. Using the World Wide Web to Connect Research and Professional Practice: Towards Evidence-Based Practice

    Directory of Open Access Journals (Sweden)

    Daniel L. Moody

    2003-01-01

    Full Text Available In most professional (applied disciplines, research findings take a long time to filter into practice, if they ever do at all. The result of this is under-utilisation of research results and sub-optimal practices. There are a number of reasons for the lack of knowledge transfer. On the "demand side", people working in professional practice have little time available to keep up with the latest research in their field. In addition, the volume of research published each year means that the average practitioner would not have time to read all the research articles in their area of interest even if they devoted all their time to it. From the "supply side", academic research is primarily focused on the production rather than distribution of knowledge. While they have highly developed mechanisms for transferring knowledge among themselves, there is little investment in the distribution of research results be-yond research communities. The World Wide Web provides a potential solution to this problem, as it provides a global information infrastructure for connecting those who produce knowledge (researchers and those who need to apply this knowledge (practitioners. This paper describes two projects which use the World Wide Web to make research results directly available to support decision making in the workplace. The first is a successful knowledge management project in a health department which provides medical staff with on-line access to the latest medical research at the point of care. The second is a project currently in progress to implement a similar system to support decision making in IS practice. Finally, we draw some general lessons about how to improve transfers of knowledge from research and practice, which could be applied in any discipline.

    Kain, Zeev N; Fortier, Michelle A; Chorney, Jill MacLaren; Mayes, Linda

    2015-04-01

    As a result of cost-containment efforts, preparation programs for outpatient surgery are currently not available to the majority of children and parents. The recent dramatic growth in the Internet presents a unique opportunity to transform how children and their parents are prepared for surgery. In this article, we describe the development of a Web-based Tailored Intervention for Preparation of parents and children undergoing Surgery (WebTIPS). A multidisciplinary taskforce agreed that a Web-based tailored intervention consisting of intake, matrix, and output modules was the preferred approach. Next, the content of the various intake variables, the matrix logic, and the output content was developed. The output product has a parent component and a child component and is described in http://surgerywebtips.com/about.php. The child component makes use of preparation strategies such as information provision, modeling, play, and coping skills training. The parent component of WebTIPS includes strategies such as information provision, coping skills training, and relaxation and distraction techniques. A reputable animation and Web design company developed a secured Web-based product based on the above description. In this article, we describe the development of a Web-based tailored preoperative preparation program that can be accessed by children and parents multiple times before and after surgery. A follow-up article in this issue of Anesthesia & Analgesia describes formative evaluation and preliminary efficacy testing of this Web-based tailored preoperative preparation program.

    Okamura, Kyoko; Bernstein, Judith; Fidler, Anne T

    2002-01-01

    The Internet has become a major source of health information for women, but information placed on the World Wide Web does not routinely undergo a peer review process before dissemination. In this study, we present an analysis of 197 infertility-related Web sites for quality and accountability, using JAMA's minimal core standards for responsible print. Only 2% of the web sites analyzed met all four recommended standards, and 50.8% failed to report any of the four. Commercial web sites were more likely to fail to meet minimum standards (71.2%) than those with educational (46.8%) or supportive (29.8%) elements. Web sites with educational and informational components were most common (70.6%), followed by commercial sites (52.8%) and sites that offered a forum for infertility support and activism (28.9%). Internet resources available to infertile patients are at best variable. The current state of infertility-related materials on the World Wide Web offers unprecedented opportunities to improve services to a growing number of e-health users. Because of variations in quality of site content, women's health clinicians must assume responsibility for a new role as information monitor. This study provides assessment tools clinicians can apply and share with clients.

    Effective communication with cancer patients and their families about their disease, treatment options, and possible outcomes may improve psychosocial outcomes. However, traditional approaches to providing information to patients, including verbal information and written booklets, have a number of shortcomings centered on their limited ability to meet patient preferences and literacy levels. New-generation Web-based technologies offer an innovative and pragmatic solution for overcoming these limitations by providing a platform for interactive information seeking, information sharing, and user-centered tailoring. The primary goal of this paper is to discuss the advantages of comprehensive and iterative Web-based technologies for health information provision and propose a four-phase framework for the development of Web-based information tools. The proposed framework draws on our experience of constructing a Web-based information tool for hematological cancer patients and their families. The framework is based on principles for the development and evaluation of complex interventions and draws on the Agile methodology of software programming that emphasizes collaboration and iteration throughout the development process. The DoTTI framework provides a model for a comprehensive and iterative approach to the development of Web-based informational tools for patients. The process involves 4 phases of development: (1) Design and development, (2) Testing early iterations, (3) Testing for effectiveness, and (4) Integration and implementation. At each step, stakeholders (including researchers, clinicians, consumers, and programmers) are engaged in consultations to review progress, provide feedback on versions of the Web-based tool, and based on feedback, determine the appropriate next steps in development. This 4-phase framework is evidence-informed and consumer-centered and could be applied widely to develop Web-based programs for a diverse range of diseases.

  1. Treatment of Wide-Neck Bifurcation Aneurysm Using "WEB Device Waffle Cone Technique".

    2018-05-01

    The endovascular treatment of wide-neck bifurcation aneurysms can be challenging and often requires the use of adjunctive techniques and devices. We report our first experience of using a waffle-cone technique adapted to the Woven Endoluminal Bridge (WEB) device in a large-neck basilar tip aneurysm, suitable in cases where the use of Y stenting or other techniques is limited due to anatomic restrictions. The procedure was complete, and angiographic occlusion of the aneurysm was achieved 24 hours post treatment, as confirmed by digital subtraction angiography. No complications occurred. The case reported here was not suitable for Y stenting or deployment of the WEB device alone, due to the small caliber of both posterior cerebral arteries and their origin at the neck level. The main advantage of this technique is that both devices have a controlled detachment system and are fully independent. To our knowledge, this technique has not been reported previously and this modality of treatment has never been described in the literature. Copyright © 2018 Elsevier Inc. All rights reserved.

    To establish a new visual educational system of virtual reality for clinical dentistry based on world wide web (WWW) webpage in order to provide more three-dimensional multimedia resources to dental students and an online three-dimensional consulting system for patients. Based on computer graphics and three-dimensional webpage technologies, the software of 3Dsmax and Webmax were adopted in the system development. In the Windows environment, the architecture of whole system was established step by step, including three-dimensional model construction, three-dimensional scene setup, transplanting three-dimensional scene into webpage, reediting the virtual scene, realization of interactions within the webpage, initial test, and necessary adjustment. Five cases of three-dimensional interactive webpage for clinical dentistry were completed. The three-dimensional interactive webpage could be accessible through web browser on personal computer, and users could interact with the webpage through rotating, panning and zooming the virtual scene. It is technically feasible to implement the visual educational system of virtual reality for clinical dentistry based on WWW webpage. Information related to clinical dentistry can be transmitted properly, visually and interactively through three-dimensional webpage.

    The most important event following the establishmenet of the Internet network was the Web introduced by Tim Berners-Lee. Websites give their owners features that allow sharing with which they can publish their content with users and visitors. In the last 5 years, we have seen some changes in the use of web. Users want to participate in content sharing and they like to interact with each other. This is known as Web 2.0. In the last year, Web 2.0 has reached maturity and now we need a smart web which will be accordingly be called Web 3.0. Web 3.0 is based on semantic web definition. Changing the way of using the web has had a clear impact on E-Tourism and its development and also on business models.

    Simple sequence repeats (SSRs) have become widely used as molecular markers in plant genetic studies due to their abundance, high allelic variation at each locus and simplicity to analyze using conventional PCR amplification. To study plants with unknown genome sequence, SSR markers from Expressed Sequence Tags (ESTs), which can be obtained from the plant mRNA (converted to cDNA), must be utilized. With the advent of high-throughput sequencing technology, huge EST sequence data have been generated and are now accessible from many public databases. However, SSR marker identification from a large in-house or public EST collection requires a computational pipeline that makes use of several standard bioinformatic tools to design high quality EST-SSR primers. Some of these computational tools are not users friendly and must be tightly integrated with reference genomic databases. A web-based bioinformatic pipeline, called EST Analysis Pipeline Plus (ESAP Plus), was constructed for assisting researchers to develop SSR markers from a large EST collection. ESAP Plus incorporates several bioinformatic scripts and some useful standard software tools necessary for the four main procedures of EST-SSR marker development, namely 1) pre-processing, 2) clustering and assembly, 3) SSR mining and 4) SSR primer design. The proposed pipeline also provides two alternative steps for reducing EST redundancy and identifying SSR loci. Using public sugarcane ESTs, ESAP Plus automatically executed the aforementioned computational pipeline via a simple web user interface, which was implemented using standard PHP, HTML, CSS and Java scripts. With ESAP Plus, users can upload raw EST data and choose various filtering options and parameters to analyze each of the four main procedures through this web interface. All input EST data and their predicted SSR results will be stored in the ESAP Plus MySQL database. Users will be notified via e-mail when the automatic process is completed and they can

    As the web has grown, so has the number of ways people use it. Today, it's not uncommon for Web users to shop, chat with friends or strangers; manage their bank accounts and exercise routines, share photos or videos and more. Online, Web forms bridge the gap between people, their information and a Web product or service. They can streamline sales or key customer actions; build communities or conversations and more. These crucial interactions not only keep businesses running, they also let people accomplish what they want. Every year, students in thousands queue up for collecting admission / application forms and then again for submitting the admission / application forms. This leads to problems in managing the applications, resulting in annoyed parents and students alike. In Chapter 1, discuss the existing admission system and some problems of current system. At KINPOE, it was needed to automate the admission process of PGTP and PDTP programs. So it was the good time to start at least with a prototype online web application for online admission system. Chapter 2 includes the process of online admission system. The online admission system is divided into four phases. Application form filling, automatic roll number allotment with fee slip generation, fee verification process and admit card printing. Chapter 3 consists of details about application development based on Advanced Development Strategy, with ASP.NET 4.0, C and database engine SQL Server 2008. Also online admission system is discussed with snapshots in this chapter. Chapter 4 includes the Deployment and testing of the Web Application. This Document is not for software developers, because it does not contain Requirement Specification and other Developers related document. This document is designed as to support Users and system administrator who will use and maintain the system. (author)

    2006-12-01

    The sensor web is a distributed, federated infrastructure much like its predecessors, the internet and the world wide web. It will be a federation of many sensor webs, large and small, under many distinct spans of control, that loosely cooperates and share information for many purposes. Realistically, it will grow piecemeal as distinct, individual systems are developed and deployed, some expressly built for a sensor web while many others were created for other purposes. Therefore, the architecture of the sensor web is of fundamental import and architectural strictures that inhibit innovation, experimentation, sharing or scaling may prove fatal. Drawing upon the architectural lessons of the world wide web, we offer a novel system architecture, the flow web, that elevates flows, sequences of messages over a domain of interest and constrained in both time and space, to a position of primacy as a dynamic, real-time, medium of information exchange for computational services. The flow web captures; in a single, uniform architectural style; the conflicting demands of the sensor web including dynamic adaptations to changing conditions, ease of experimentation, rapid recovery from the failures of sensors and models, automated command and control, incremental development and deployment, and integration at multiple levels—in many cases, at different times. Our conception of sensor webs—dynamic amalgamations of sensor webs each constructed within a flow web infrastructure—holds substantial promise for earth science missions in general, and of weather, air quality, and disaster management in particular. Flow webs, are by philosophy, design and implementation a dynamic infrastructure that permits massive adaptation in real-time. Flows may be attached to and detached from services at will, even while information is in transit through the flow. This concept, flow mobility, permits dynamic integration of earth science products and modeling resources in response to real

    International Nuclear Information System (INIS)

    Watanabe, Norio; Hirano, Masashi

    1999-01-01

    The International Nuclear Event Scale (INES) is a means designed for providing prompt, clear and consistent information related to nuclear events, that occurred at nuclear facilities, and facilitating communication between the nuclear community, the media and the public. The INES is jointly operated by the IAEA and the OECD-NEA. Nuclear events reported are rated by the Scale', a consistent safety significance indicator. The scale runs from level 0, for events with no safety significance, to level 7 for a major accident with widespread health and environmental effects. The Japan Atomic Energy Research Institute (JAERI) has been promptly translating the INES reports into Japanese and developing a world-wide-web database for the Japanese translation, aiming at more efficient utilization of the INES information inside Japan. The present paper briefly introduces the definitions of INES rating levels and the scope of the Scale, and describes the outlines of the database (the information stored in the database, its functions and how to use it). As well, technical use of the INES reports and the availability/ effectiveness of the database are discussed. (author)

    In the era where Internet technology has grown rapidly, information is now at your fingertips. Web site is considered as an important medium and widely used whether for the purposes of promoting products and services or as an effective way to disseminate general information about the organization, companies or individuals. Nowadays, a general term such as Web 2.0 is almost out of date and is now entering the era of the Real World Web. For government agencies for instance, official web site is an important and effective tool for dissemination and communication of information to the public. In the view of Web master for a government agency, a number of issues and challenges may arise. They might face the same issues and challenges but they way to handle them are differ from one agency to another, depending on the culture, special rules and regulations applied and shared values among the staff. This paper will discuss these issues and challenges as well as applicable solutions based on our experiences. (author)

  1. Glue ear: how good is the information on the World Wide Web?

    Science.gov (United States)

    Ritchie, L; Tornari, C; Patel, P M; Lakhani, R

    2016-02-01

    This paper objectively evaluates current information available to the general public related to glue ear on the World Wide Web. The term 'glue ear' was typed into the 3 most frequently used internet search engines - Google, Bing and Yahoo - and the first 20 links were analysed. The first 400 words of each page were used to calculate the Flesch-Kincaid readability score. Each website was subsequently graded using the Discern instrument, which gauges quality and content of literature. The websites Webmd.boots.com, Bupa.co.uk and Patient.co.uk received the highest overall scores. These reflected top scores in either readability or Discern instrument assessment, but not both. Readability and Discern scores increased with the presence of a marketing or advertising incentive. The Patient.co.uk website had the highest Discern score and third highest readability score. There is huge variation in the quality of information available to patients on the internet. Some websites may be accessible to a wide range of reading ages but have poor quality content, and vice versa. Clinicians should be aware of indicators of quality, and use validated instruments to assess and recommend literature.

    The accelerator control system for the JAERI ERL-FEL is a PC-based distributed control system. The accelerator status record is stored automatically through the control system to analyze the influence on the electron beam. In order to handle effectively a large number of stored data, it is necessary that the required data can be searched and visualized in easy operation. For this reason, a web database (DB) system which can search of the required data and display visually on a web browser was developed by using open source software. With introduction of this system, accelerator operators can monitor real-time information anytime, anywhere through a web browser. Development of the web DB system is described in this paper.

  5. Caught in the Web

    The World-Wide Web may have taken the Internet by storm, but many people would be surprised to learn that it owes its existence to CERN. Around half the world's particle physicists come to CERN for their experiments, and the Web is the result of their need to share information quickly and easily on a global scale. Six years after Tim Berners-Lee's inspired idea to marry hypertext to the Internet in 1989, CERN is handing over future Web development to the World-Wide Web Consortium, run by the French National Institute for Research in Computer Science and Control, INRIA, and the Laboratory for Computer Science of the Massachusetts Institute of Technology, MIT, leaving itself free to concentrate on physics. The Laboratory marked this transition with a conference designed to give a taste of what the Web can do, whilst firmly stamping it with the label ''Made in CERN''. Over 200 European journalists and educationalists came to CERN on 8 - 9 March for the World-Wide Web Days, resulting in wide media coverage. The conference was opened by UK Science Minister David Hunt who stressed the importance of fundamental research in generating new ideas. ''Who could have guessed 10 years ago'', he said, ''that particle physics research would lead to a communication system which would allow every school to have the biggest library in the world in a single computer?''. In his introduction, the Minister also pointed out that ''CERN and other basic research laboratories help to break new technological ground and sow the seeds of what will become mainstream manufacturing in the future.'' Learning the jargon is often the hardest part of coming to grips with any new invention, so CERN put it at the top of the agenda. Jacques Altaber, who helped introduce the Internet to CERN in the early 1980s, explained that without the Internet, the Web couldn't exist. The Internet began as a US Defense Department research project in the 1970s and has grown into a global network-ofnetworks linking some

    This pilot study tested the effects of an interactive nutrition education Web site on fruit, vegetable, and fat consumption in minority adolescents genetically at risk for Type 2 diabetes. A one-group nonexperimental pretest, posttest focus group design was used. Twenty-one sixth-grade to eighth-grade junior high adolescents who were minorities volunteered to participate. Participants received 5 hours of Web-based nutrition education over 3 weeks. A significant difference in fat consumption was supported from the computerized dietary assessment. No difference was found in fruit or vegetable consumption. Comparative data indicated a rise in body mass index (BMI) percentile from 88.03 (1999) to 88.40 (2002; boys) and 88.25 (1999) to 91.2 (2002; girls). Focus group responses supported the satisfaction of adolescents in the study with the use of the Web-based intervention for nutrition education. Healthy eating interventions using Web-based nutrition education should be further investigated with adolescents.

    Full Text Available The advent of the World Wide Web is arguably amongst the most important changes that have occurred since the 1990s in the business landscape. It has fueled the rise of new industries, supported the convergence and reshaping of existing ones and enabled the development of new business models. During this time the web has evolved tremendously from a relatively static pagedisplay tool to a massive network of user-generated content, collective intelligence, applications and hypermedia. As technical standards continue to evolve, business models catch-up to the new capabilities. New ways of creating value, distributing it and profiting from it emerge more rapidly than ever. In this paper we explore how the World Wide Web and business models evolve and we identify avenues for future research in light of the web‟s ever-evolving nature and its influence on business models.

    The rapid growth in popularity of web applications gives rise to a plethora of reusable graphical components, such as Google Chart Tools and JQuery Sparklines, implemented in JavaScript and run inside a web browser. In the paper we describe the tool that allows for seamless integration of web-based widgets into WinCC Open Architecture, the SCADA system used commonly at CERN to build complex Human-Machine Interfaces. Reuse of widely available widget libraries and pushing the development efforts to a higher abstraction layer based on a scripting language allow for significant reduction in maintenance of the code in multi-platform environments compared to those currently used in C++ visualization plugins. Adequately designed interfaces allow for rapid integration of new web widgets into WinCC OA. At the same time, the mechanisms familiar to HMI developers are preserved, making the use of new widgets n ative . Perspectives for further integration between the realms of WinCC OA and Web development are also discussed.

    2018-03-15

    Following the type II CRISPR-Cas9 system, type V CRISPR-Cpf1 endonucleases have been found to be applicable for genome editing in various organisms in vivo. However, there are as yet no web-based tools capable of optimally selecting guide RNAs (gRNAs) among all possible genome-wide target sites. Here, we present Cpf1-Database, a genome-wide gRNA library design tool for LbCpf1 and AsCpf1, which have DNA recognition sequences of 5'-TTTN-3' at the 5' ends of target sites. Cpf1-Database provides a sophisticated but simple way to design gRNAs for AsCpf1 nucleases on the genome scale. One can easily access the data using a straightforward web interface, and using the powerful collections feature one can easily design gRNAs for thousands of genes in short time.

  18. Efficient development of web applications for remote participation using Ruby on Rails

    Large-scale experiments such as ITER require international collaboration, and remote participation plays an important role in carrying out such experiments. Web-based applications are useful tools for scientists participating in experiments remotely using personal computers. Since the participants typically download web-based applications to their computer each time they access the web servers, they do not need to install extra software in order to use these applications. In addition, the application developers do not need to distribute the latest program files each time they are modified, thus reducing maintenance costs for remote participation systems. For these reasons, we have been developing web-based applications for the LHD experiments at NIFS. In a previous study, we showed the benefits of using Ruby on Rails (RoR) to develop web-based applications for analysis code. We thought this approach would also be useful for developing applications for remote participation. Therefore, we have developed several web-based applications using RoR for participating in the LHD experiments. These applications include a data viewer and a scheduler of experiments. The main reason to adopt RoR for this purpose is its efficiency for developing web-based applications. For example, to develop a data viewer, we used an existing program running on an X-Windows System. Using RoR, we could minimize the modifications of the existing programs to add web interfaces. In this paper, we will report a web-based application developed using RoR for the LHD experiment. We will also discuss the benefits of using RoR in developing remote participation tools.

    The Space Physics Data Facility (SPDF) Web services provides a distributed programming interface to a portion of the SPDF software. (A general description of Web services is available at http://www.w3.org/ and in many current software-engineering texts and articles focused on distributed programming.) The SPDF Web services distributed programming interface enables additional collaboration and integration of the SPDF software system with other software systems, in furtherance of the SPDF mission to lead collaborative efforts in the collection and utilization of space physics data and mathematical models. This programming interface conforms to all applicable Web services specifications of the World Wide Web Consortium. The interface is specified by a Web Services Description Language (WSDL) file. The SPDF Web services software consists of the following components: 1) A server program for implementation of the Web services; and 2) A software developer s kit that consists of a WSDL file, a less formal description of the interface, a Java class library (which further eases development of Java-based client software), and Java source code for an example client program that illustrates the use of the interface.

    Full Text Available Groundwater has received increasing attention as an important strategic water resource for adaptation to climate change. In this regard, the separation of baseflow from streamflow and the analysis of recession curves make a significant contribution to integrated river basin management. The United States Geological Survey (USGS RECESS model adopting the master-recession curve (MRC method can enhance the accuracy with which baseflow may be separated from streamflow, compared to other baseflow-separation schemes that are more limited in their ability to reflect various watershed/aquifer characteristics. The RECESS model has been widely used for the analysis of hydrographs, but the applications using RECESS were only available through Microsoft-Disk Operating System (MS-DOS. Thus, this study aims to develop a web-based RECESS model for easy separation of baseflow from streamflow, with easy applications for ungauged regions. RECESS on the web derived the alpha factor, which is a baseflow recession constant in the Soil Water Assessment Tool (SWAT, and this variable was provided to SWAT as the input. The results showed that the alpha factor estimated from the web-based RECESS model improved the predictions of streamflow and recession. Furthermore, these findings showed that the baseflow characteristics of the ungauged watersheds were influenced by the land use and slope angle of watersheds, as well as by precipitation and streamflow.

    The low-level consistency of the cytodiagnosis of uterine cervical atypical squamous epithelial cells of undetermined significance (ASC-US) employing the Bethesda System has been reported, suggesting the necessity of a wide survey. We presented cases judged as ASC-US on the Web and analyzed the voting results to investigate ASC-US cytologically. Cytology samples from 129 patients diagnosed with ASC-US were used. Images of several atypical cells observed in these cases were presented on the Web. The study, based on the voting results, was presented and opinions were exchanged at the meeting of the Japanese Society of Clinical Cytology. The final diagnosis of ASC-US was benign lesions in 76 cases and low- and high-grade squamous intraepithelial lesions in 44, but no definite diagnosis could be made for the remaining 9. The total number of votes was 17,884 with a 36.5% consistency of cases judged as ASC-US. Benign cases were divided into 6 categories. Four categories not corresponding to the features of koilocytosis and small abnormal keratinized cells were judged as negative for an intraepithelial lesion or malignancy at a high rate. A Web-based survey would be useful which could be viewed at any time and thereby facilitate the sharing of cases to increase consistency. Copyright © 2011 S. Karger AG, Basel.

    The transformative power of the Internet on all aspects of daily life, including health care, has been widely recognized both in the scientific literature and in public discourse. Viewed through the various lenses of diverse academic disciplines, these transformations reveal opportunities realized, the promise of future advances, and even potential problems created by the penetration of the World Wide Web for both individuals and for society at large. Discussions about the clinical and health research implications of the widespread adoption of information technologies, including the Internet, have been subsumed under the disciplinary label of Medicine 2.0. More recently, however, multi-disciplinary research has emerged that is focused on the achievement and promise of the Web itself, as it relates to healthcare issues. In this paper, we explore and interrogate the contributions of the burgeoning field of Web Science in relation to health maintenance, health care, and health policy. From this, we introduce Health Web Science as a subdiscipline of Web Science, distinct from but overlapping with Medicine 2.0. This paper builds on the presentations and subsequent interdisciplinary dialogue that developed among Web-oriented investigators present at the 2012 Medicine 2.0 Conference in Boston, Massachusetts.

    Full Text Available The World Wide Web influences education and our lives in many ways. Nowadays, Web-based homework has been becoming widespread practice in physics courses and some other courses as well. Although are some disputes whether this is an encouraging or risky development for student learning, there is limited research assessing the pedagogical effect of changing the medium from written, hand-graded homework to online oriented, computer-graded homework. In this study, web-oriented homework system is developed to assess students’ introductory physics course performance. Later on, these results are compared with paper-based (peer homework performance for mid enrollment physics courses. One of two identical sections of introductory physics course students received paper-based, hand graded group homework while the other received the individual web-based homework. Then two groups’ on conceptual and problem-solving performance measures are compared. No significant differences were found in students’ Force Concept Inventory (FCI test scores; however, average homework performance scores were significant that could be attributed to the homework method used in favor of paper-based peer homework group.

    Surveillance of health care-associated infections is an essential component of infection prevention programs, but conventional systems are labor intensive and performance dependent. To develop an automatic surveillance and classification system for health care-associated bloodstream infection (HABSI), and to evaluate its performance by comparing it with a conventional infection control personnel (ICP)-based surveillance system. We developed a Web-based system that was integrated into the medical information system of a 2200-bed teaching hospital in Taiwan. The system automatically detects and classifies HABSIs. In this study, the number of computer-detected HABSIs correlated closely with the number of HABSIs detected by ICP by department (n=20; r=.999 Psystem performed excellently with regard to sensitivity (98.16%), specificity (99.96%), positive predictive value (95.81%), and negative predictive value (99.98%). The system enabled decreasing the delay in confirmation of HABSI cases, on average, by 29 days. This system provides reliable and objective HABSI data for quality indicators, improving the delay caused by a conventional surveillance system.

  15. An Efficient Approach for Web Indexing of Big Data through Hyperlinks in Web Crawling

    2015-01-01

    Web Crawling has acquired tremendous significance in recent times and it is aptly associated with the substantial development of the World Wide Web. Web Search Engines face new challenges due to the availability of vast amounts of web documents, thus making the retrieved results less applicable to the analysers. However, recently, Web Crawling solely focuses on obtaining the links of the corresponding documents. Today, there exist various algorithms and software which are used to crawl links from the web which has to be further processed for future use, thereby increasing the overload of the analyser. This paper concentrates on crawling the links and retrieving all information associated with them to facilitate easy processing for other uses. In this paper, firstly the links are crawled from the specified uniform resource locator (URL) using a modified version of Depth First Search Algorithm which allows for complete hierarchical scanning of corresponding web links. The links are then accessed via the source code and its metadata such as title, keywords, and description are extracted. This content is very essential for any type of analyser work to be carried on the Big Data obtained as a result of Web Crawling. PMID:26137592

    The silicon web process takes advantage of natural crystallographic stabilizing forces to grow long, thin single crystal ribbons directly from liquid silicon. The ribbon, or web, is formed by the solidification of a liquid film supported by surface tension between two silicon filaments, called dendrites, which border the edges of the growing strip. The ribbon can be propagated indefinitely by replenishing the liquid silicon as it is transformed to crystal. The dendritic web process has several advantages for achieving low cost, high efficiency solar cells. These advantages are discussed.

  19. Caught in the Web

    International Nuclear Information System (INIS)

    1995-01-01

    The World-Wide Web may have taken the Internet by storm, but many people would be surprised to learn that it owes its existence to CERN. Around half the world's particle physicists come to CERN for their experiments, and the Web is the result of their need to share information quickly and easily on a global scale. Six years after Tim Berners-Lee's inspired idea to marry hypertext to the Internet in 1989, CERN is handing over future Web development to the World-Wide Web Consortium, run by the French National Institute for Research in Computer Science and Control, INRIA, and the Laboratory for Computer Science of the Massachusetts Institute of Technology, MIT, leaving itself free to concentrate on physics. The Laboratory marked this transition with a conference designed to give a taste of what the Web can do, whilst firmly stamping it with the label ''Made in CERN''. Over 200 European journalists and educationalists came to CERN on 8 - 9 March for the World-Wide Web Days, resulting in wide media coverage. The conference was opened by UK Science Minister David Hunt who stressed the importance of fundamental research in generating new ideas. ''Who could have guessed 10 years ago'', he said, ''that particle physics research would lead to a communication system which would allow every school to have the biggest library in the world in a single computer?''. In his introduction, the Minister also pointed out that ''CERN and other basic research laboratories help to break new technological ground and sow the seeds of what will become mainstream manufacturing in the future.'' Learning the jargon is often the hardest part of coming to grips with any new invention, so CERN put it at the top of the agenda. Jacques Altaber, who helped introduce the Internet to CERN in the early 1980s, explained that without the Internet, the Web couldn't exist. The Internet began as a US Defense

    Full Text Available In a world where the internet and its image are becoming more and more important, this study is about the importance of Investment and Financial Services Companies web sites. Market competition, creates the need of studies, focused on assessing and analyzing the websites of companies who are active in this sector. Our study wants to respond at several questions related to Romanian Investment and Financial Services Companies web sites through four dimensions: content, layout, handling and interactivity. Which web sites are best and from what point of view? Where should financial services companies direct their investments to differentiate themselves and their sites? In fact we want to rank the 58 Investment and Financial Services Companies web sites based on 127 criteria. There are numerous methods for evaluating web pages. The evaluation methods are similar from the structural point of view and the most popular are: Serqual, Sitequal, Webqual / Equal EtailQ, Ewam, e-Serqual, WebQEM (Badulescu, 2008:58. In the paper: "Assessment of Romanian Banks E-Image: A Marketing Perspective" (Catana, Catana and Constantinescu, 2006: 4 the authors point out that there are at least four complex variables: accessibility, functionality, performance and usability. Each of these can be decomposed into simple ones. We used the same method, and we examined from the utility point of view, 58 web sites of Investment and Financial Services Companies based on 127 criteria following a procedure developed by Institut fur ProfNet Internet Marketing, Munster (Germany. The data collection period was 1-30 September 2010. The results show that there are very large differences between corporate sites; their creators are concentrating on the information required by law and aesthetics, neglecting other aspects as communication and online service. In the future we want to extend this study at international level, by applying the same methods of research in 5 countries from

    2008-11-01

    Polymers are among the most important classes of materials but are only inadequately supported by modern informatics. The paper discusses the reasons why polymer informatics is considerably more challenging than small molecule informatics and develops a vision for the computer-aided design of polymers, based on modern semantic web technologies. The paper then discusses the development of Polymer Markup Language (PML). PML is an extensible language, designed to support the (structural) representation of polymers and polymer-related information. PML closely interoperates with Chemical Markup Language (CML) and overcomes a number of the previously identified challenges.

    The Semantic Web, which is intended to establish a machine-understandable Web, is currently changing from being an emerging trend to a technology used in complex real-world applications. A number of standards and techniques have been developed by the World Wide Web Consortium (W3C), e.g., the Resource Description Framework (RDF), which provides a general method for conceptual descriptions for Web resources, and SPARQL, an RDF querying language. Recent examples of large RDF data with billions of facts include the UniProt comprehensive catalog of protein sequence, function and annotation data, t

  12. Testing Quantum Models of Conjunction Fallacy on the World Wide Web

    The `conjunction fallacy' has been extensively debated by scholars in cognitive science and, in recent times, the discussion has been enriched by the proposal of modeling the fallacy using the quantum formalism. Two major quantum approaches have been put forward: the first assumes that respondents use a two-step sequential reasoning and that the fallacy results from the presence of `question order effects'; the second assumes that respondents evaluate the cognitive situation as a whole and that the fallacy results from the `emergence of new meanings', as an `effect of overextension' in the conceptual conjunction. Thus, the question arises as to determine whether and to what extent conjunction fallacies would result from `order effects' or, instead, from `emergence effects'. To help clarify this situation, we propose to use the World Wide Web as an `information space' that can be interrogated both in a sequential and non-sequential way, to test these two quantum approaches. We find that `emergence effects', and not `order effects', should be considered the main cognitive mechanism producing the observed conjunction fallacies.

    Antimicrobial stewardship programs aim to reduce inappropriate hospital antimicrobial use. At the Johns Hopkins Children's Medical and Surgical Center (Baltimore, MD), we implemented a World Wide Web-based antimicrobial restriction program to address problems with the existing restriction program. A user survey identified opportunities for improvement of an existing antimicrobial restriction program and resulted in subsequent design, implementation, and evaluation of a World Wide Web-based antimicrobial restriction program at a 175-bed, tertiary care pediatric teaching hospital. The program provided automated clinical decision support, facilitated approval, and enhanced real-time communication among prescribers, pharmacists, and pediatric infectious diseases fellows. Approval status, duration, and rationale; missing request notifications; and expiring approvals were stored in a database that is accessible via a secure Intranet site. Before and after implementation of the program, user satisfaction, reports of missed and/or delayed doses, antimicrobial dispensing times, and cost were evaluated. After implementation of the program, there was a $370,069 reduction in projected annual cost associated with restricted antimicrobial use and an 11.6% reduction in the number of dispensed doses. User satisfaction increased from 22% to 68% and from 13% to 69% among prescribers and pharmacists, respectively. There were 21% and 32% reductions in the number of prescriber reports of missed and delayed doses, respectively, and there was a 37% reduction in the number of pharmacist reports of delayed approvals; measured dispensing times were unchanged (P = .24). In addition, 40% fewer restricted antimicrobial-related phone calls were noted by the pharmacy. The World Wide Web-based antimicrobial approval program led to improved communication, more-efficient antimicrobial administration, increased user satisfaction, and significant cost savings.

    2012-01-01

    The WebSocket allows asynchronous full-duplex communication between a Web-based (i.e. Java Script-based) application and a Web-server. WebSocket started as a part of HTML5 standardization but has now been separated from HTML5 and has been developed independently. Using WebSocket, it becomes easy to develop platform independent presentation layer applications for accelerator and beamline control software. In addition, a Web browser is the only application program that needs to be installed on client computer. The WebSocket-based applications communicate with the WebSocket server using simple text-based messages, so WebSocket is applicable message-based control system like MADOCA, which was developed for the SPring-8 control system. A simple WebSocket server for the MADOCA control system and a simple motor control application were successfully made as a first trial of the WebSocket control application. Using Google-Chrome (version 13.0) on Debian/Linux and Windows 7, Opera (version 11.0) on Debian/Linux and Safari (version 5.0.3) on Mac OS X as clients, the motors can be controlled using a WebSocket-based Web-application. Diffractometer control application use in synchrotron radiation diffraction experiment was also developed. (author)

    2008-01-01

    Software-based medical knowledge packages (MKPs) are packages of highly structured medical knowledge that can be integrated into various health-care information systems or the World Wide Web. They have been established to provide different forms of clinical decision support such as textual interpretation of combinations of laboratory rest results, generating diagnostic hypotheses as well as confirmed and excluded diagnoses to support differential diagnosis in internal medicine, or for early identification and automatic monitoring of hospital-acquired infections. Technically, an MKP may consist of a number of inter-connected Arden Medical Logic Modules. Several MKPs have been integrated thus far into hospital, laboratory, and departmental information systems. This has resulted in useful and widely accepted software-based clinical decision support for the benefit of the patient, the physician, and the organization funding the health care system.

    Full Text Available The World Wide Web became one of the most valuable resources for information retrievals and knowledge discoveries due to the permanent increasing of the amount of data available online. Taking into consideration the web dimension, the users get easily lost in the web’s rich hyper structure. Application of data mining methods is the right solution for knowledge discovery on the Web. The knowledge extracted from the Web can be used to raise the performances for Web information retrievals, question answering and Web based data warehousing. In this paper, I provide an introduction of Web mining categories and I focus on one of these categories: the Web structure mining. Web structure mining, one of three categories of web mining for data, is a tool used to identify the relationship between Web pages linked by information or direct link connection. It offers information about how different pages are linked together to form this huge web. Web Structure Mining finds hidden basic structures and uses hyperlinks for more web applications such as web search.

    2012-11-01

    Mental health first aid guidelines provide the public with consensus-based information about how to assist someone who is developing a mental illness or experiencing a mental health crisis. The aim of the current study was to evaluate the usefulness and impact of the guidelines on web users who download them. Web users who downloaded the documents were invited to respond to an initial demographic questionnaire, then a follow up about how the documents had been used, their perceived usefulness, whether first-aid situations had been encountered and if these were influenced by the documents. Over 9.8 months, 706 web users responded to the initial questionnaire and 154 responded to the second. A majority reported downloading the document because their job involved contact with people with mental illness. Sixty-three web users reported providing first aid, 44 of whom reported that the person they were assisting had sought professional care as a result of their suggestion. Twenty-three web users reported seeking care themselves. A majority of those who provided first aid reported feeling that they had been successful in helping the person, that they had been able to assist in a way that was more knowledgeable, skilful and supportive, and that the guidelines had contributed to these outcomes. Information made freely available on the Internet, about how to provide mental health first aid to someone who is developing a mental health problem or experiencing a mental health crisis, is associated with more positive, empathic and successful helping behaviours. © 2012 Wiley Publishing Asia Pty Ltd.

    We describe a relatively new effort within CMS to converge on a set of web based tools, using state of the art industry techniques, to engage with the CMS offline computing system. CMS collaborators require tools to monitor various components of the computing system and interact with the system itself. The current state of the various CMS web tools is described along side current planned developments. The CMS collaboration comprises of nearly 3000 people from all over the world. As well as its collaborators, its computing resources are spread all over globe and are accessed via the LHC grid to run analysis, large scale production and data transfer tasks. Due to the distributed nature of collaborators effective provision of collaborative tools is essential to maximise physics exploitation of the CMS experiment, especially when the size of the CMS data set is considered. CMS has chosen to provide such tools over the world wide web as a top level service, enabling all members of the collaboration to interact with the various offline computing components. Traditionally web interfaces have been added in HEP experiments as an afterthought. In the CMS offline we have decided to put web interfaces, and the development of a common CMS web framework, on an equal footing with the rest of the offline development. Tools exist within CMS to transfer and catalogue data (PhEDEx and DBS/DLS), run Monte Carlo production (ProdAgent) and submit analysis (CRAB). Effective human interfaces to these systems are required for users with different agendas and practical knowledge of the systems to effectively use the CMS computing system.

    Thermally generated stresses in the growing web crystal were reduced. These stresses, which if too high cause the ribbon to degenerate, were reduced by a factor of three, resulting in the demonstrated growth of high-quality web crystals to widths of 5.4 cm. This progress was brought about chiefly by the application of thermal models to the development of low-stress growth configurations. A new temperature model was developed which can analyze the thermal effects of much more complex lid and top shield configurations than was possible with the old lumped shield model. Growth experiments which supplied input data such as actual shield temperature and melt levels were used to verify the modeling results. Desirable modifications in the melt level-sensing circuitry were made in the new experimental web growth furnace, and this furnace has been used to carry out growth experiments under steady-state conditions. New growth configurations were tested in long growth runs at Westinghouse AESD which produced wider, lower stress and higher quality web crystals than designs previously used.

    The growth of silicon dendritic web for photovoltaic applications was investigated. The application of a thermal model for calculating buckling stresses as a function of temperature profile in the web is discussed. Lid and shield concepts were evaluated to provide the data base for enhancing growth velocity. An experimental web growth machine which embodies in one unit the mechanical and electronic features developed in previous work was developed. In addition, evaluation of a melt level control system was begun, along with preliminary tests of an elongated crucible design. The economic analysis was also updated to incorporate some minor cost changes. The initial applications of the thermal model to a specific configuration gave results consistent with experimental observation in terms of the initiation of buckling vs. width for a given crystal thickness.

Rapid developments in IT & global competition calls for many changes in basic CAD/CAM/CAPP/CNC manufacturing chain of operations. ‘STEP-NC’ an enhancement to STEP for operating CNC machines, creating new opportunities for collaborative, concurrent, adaptive works across the manufacturing chain of operations. Schemas and data models defined by ISO14649 in liaison with ISO10303 standards made STEP-NC file rich with feature based, rather than mere point to point information of G/M Code format. But one needs to have a suitable information system to understand and modify these files. Various STEP-NC information systems are reviewed to understand the suitability of STEP-NC for web manufacturing. Present work also deals with the development of an adaptor which imports STEP-NC file, organizes its information, allowing modifications to entity values and finally generates a new STEP-NC file to export. The system is designed and developed to work on web to avail additional benefits through the web and also to be part of a proposed ‘Web based STEP-NC manufacturing platform’ which is under development and explained as future scope.

    2013-05-01

    This paper describes the development of a web-GIS solution in which urban residents, from Buzau City, could be involved in decision-support process of water companies, in order to reduce water losses, by collecting information directly from citizens. In recent years, reducing material and economic losses, recorded in the entire municipal networks management process has become the main focus of public companies in Romania. Due to problems complexity that arise in collecting information from citizens and issues identified in urban areas, more analyzes were required related to web-GIS solutions used in areas such as local government, public utilities, environmental protection or financial management. Another important problem is the poor infrastructure development of spatial databases founded in public companies, and connection to web platforms. Developing the entire communication process between residents and municipal companies has required the use of concept "citizen-sensor" in the entire reporting process. Reported problems are related to water distribution networks with the possibility of covering the entire public utilities infrastructure.

    We study numerically the spectrum and eigenstate properties of the Google matrix of various examples of directed networks such as vocabulary networks of dictionaries and university World Wide Web networks. The spectra have gapless structure in the vicinity of the maximal eigenvalue for Google damping parameter α equal to unity. The vocabulary networks have relatively homogeneous spectral density, while university networks have pronounced spectral structures which change from one university to another, reflecting specific properties of the networks. We also determine specific properties of eigenstates of the Google matrix, including the PageRank. The fidelity of the PageRank is proposed as a characterization of its stability.

    Full Text Available Information growth in the web medium has required the necessity of archiving these information to transmit them to future generations. Web archiving is a versatile application which covers technical, legal and organizational dimensions. Any stage within the life cycle of digital information is critically important for the information in web environment. All over the world, many countries have started web archiving efforts through the leadership of their national libraries and attempted to carry these initiatives on a legal bases. In the light of these developments, this paper examines the necessity and major techniques in web archiving and it also discuss national and international web archiving projects.

    2004-01-01

    Introducing clinical staff education, along with new policies and procedures, to over 50 different clinical sites can be a challenge. As any staff educator will confess, getting people to attend an educational inservice session can be difficult. Clinical staff request training, but no one has time to attend training sessions. Putting the training along with the policies and other information into "neat" concise packages via the computer and over the company's intranet was the way to go. However, how do you bring the clinics online when some of the clinical staff may still be reluctant to turn on their computers for anything other than to gather laboratory results? Developing an easy, fun, and accessible Web page was the answer. This article outlines the development of the first training Web page at the University of Wisconsin Medical Foundation, Madison, WI.

    Watson, Val; Chancellor, Marisa K. (Technical Monitor)

    1996-01-01

    Two new technologies, the FASTexpedition and Remote FAST, have been developed that provide remote, 3D (three dimensional), high resolution, dynamic, interactive viewing of scientific data. The FASTexpedition permits one to access scientific data from the World Wide Web, take guided expeditions through the data, and continue with self controlled expeditions through the data. Remote FAST permits collaborators at remote sites to simultaneously view an analysis of scientific data being controlled by one of the collaborators. Control can be transferred between sites. These technologies are now being used for remote collaboration in joint university, industry, and NASA projects. Also, NASA Ames Research Center has initiated a project to make scientific data and guided expeditions through the data available as FASTexpeditions on the World Wide Web for educational purposes. Previously, remote visualization of dynamic data was done using video format (transmitting pixel information) such as video conferencing or MPEG (Motion Picture Expert Group) movies on the Internet. The concept for this new technology is to send the raw data (e.g., grids, vectors, and scalars) along with viewing scripts over the Internet and have the pixels generated by a visualization tool running on the viewers local workstation. The visualization tool that is currently used is FAST (Flow Analysis Software Toolkit). The advantages of this new technology over using video format are: (1) The visual is much higher in resolution (1280x1024 pixels with 24 bits of color) than typical video format transmitted over the network. (2) The form of the visualization can be controlled interactively (because the viewer is interactively controlling the visualization tool running on his workstation). (3) A rich variety of guided expeditions through the data can be included easily. (4) A capability is provided for other sites to see a visual analysis of one site as the analysis is interactively performed. Control of

    A key question regarding the future of the semantic web is "how will we acquire structured information to populate the semantic web on a vast scale?" One approach is to enter this information manually. A second approach is to take advantage of pre-existing databases, and to develop common ontologies, publishing standards, and reward systems to make this data widely accessible. We consider here a third approach: developing software that automatically extracts structured information from unstructured text present on the web. We also describe preliminary results demonstrating that machine learning algorithms can learn to extract tens of thousands of facts to populate a diverse ontology, with imperfect but reasonably good accuracy.

    The development of Web-based interventions for substance abuse in Latin America is a new field of interest with great potential for expansion to other Spanish-speaking countries. This paper describes a project aimed to develop and evaluate the usability of the Web-based Help Program for Drug Abuse and Depression (Programa de Ayuda para Abuso de Drogas y Depresión, PAADD, in Spanish) and also to construct a systematic frame of reference for the development of future Web-based programs. The PAADD aims to reduce substance use and depressive symptoms with cognitive behavioral techniques translated into Web applications, aided by the participation of a counselor to provide support and guidance. This Web-based intervention includes 4 steps: (1) My Starting Point, (2) Where Do I Want to Be? (3) Strategies for Change, and (4) Maintaining Change. The development of the program was an interactive multistage process. The first stage defined the core structure and contents, which were validated in stage 2 by a group of 8 experts in addiction treatment. Programming of the applications took place in stage 3, taking into account 3 types of end users: administrators, counselors, and substance users. Stage 4 consisted of functionality testing. In stage 5, a total of 9 health professionals and 20 drug users currently in treatment voluntarily interacted with the program in a usability test, providing feedback about adjustments needed to improve users' experience. The main finding of stage 2 was the consensus of the health professionals about the cognitive behavioral strategies and techniques included in PAADD being appropriate for changing substance use behaviors. In stage 5, the health professionals found the functionalities easy to learn; their suggestions were related to the page layout, inclusion of confirmation messages at the end of activities, avoiding "read more" links, and providing feedback about every activity. On the other hand, the users said the information presented

    Full Text Available Abstract Technology advances as well as the emergence of large scale multimedia applications and the revolution of the World Wide Web has changed the world into a digital age. Anybody can use their mobile phone to take a photo at any time anywhere and upload that image to ever growing image databases. Development of effective techniques for visual and multimedia retrieval systems is one of the most challenging and important directions of the future research. This paper proposes an effective combined feature for web based image retrieval. Frequently used colour and texture features are explored in order to develop a combined feature for this purpose. Widely used three colour features Colour moments Colour coherence vector and Colour Correlogram and three texture features Grey Level Co-occurrence matrix Tamura features and Gabor filter were analyzed for their performance. Precision and Recall were used to evaluate the performance of each of these techniques. By comparing precision and recall values the methods that performed best were taken and combined to form a hybrid feature. The developed combined feature was evaluated by developing a web based CBIR system. A web crawler was used to first crawl through Web sites and images found in those sites are downloaded and the combined feature representation technique was used to extract image features. The test results indicated that this web system can be used to index web images with the combined feature representation schema and to find similar images. Random image retrievals using the web system shows that the combined feature can be used to retrieve images belonging to the general image domain. Accuracy of the retrieval can be noted high for natural images like outdoor scenes images of flowers etc. Also images which have a similar colour and texture distribution were retrieved as similar even though the images were belonging to deferent semantic categories. This can be ideal for an artist who wants

  11. Web accessibility standards and disability: developing critical perspectives on accessibility.

    Science.gov (United States)

    Lewthwaite, Sarah

    2014-01-01

    Currently, dominant web accessibility standards do not respect disability as a complex and culturally contingent interaction; recognizing that disability is a variable, contrary and political power relation, rather than a biological limit. Against this background there is clear scope to broaden the ways in which accessibility standards are understood, developed and applied. Commentary. The values that shape and are shaped by legislation promote universal, statistical and automated approaches to web accessibility. This results in web accessibility standards conveying powerful norms fixing the relationship between technology and disability, irrespective of geographical, social, technological or cultural diversity. Web accessibility standards are designed to enact universal principles; however, they express partial and biopolitical understandings of the relation between disability and technology. These values can be limiting, and potentially counter-productive, for example, for the majority of disabled people in the "Global South" where different contexts constitute different disabilities and different experiences of web access. To create more robust, accessible outcomes for disabled people, research and standards practice should diversify to embrace more interactional accounts of disability in different settings. Implications for Rehabilitation Creating accessible experiences is an essential aspect of rehabilitation. Web standards promote universal accessibility as a property of an online resource or service. This undervalues the importance of the user's intentions, expertize, their context, and the complex social and cultural nature of disability. Standardized, universal approaches to web accessibility may lead to counterproductive outcomes for disabled people whose impairments and circumstances do not meet Western disability and accessibility norms. Accessible experiences for rehabilitation can be enhanced through an additional focus on holistic approaches to

    Departing from the widespread use of the internet in modern society and the emerging use of web applications in healthcare this project captures persons' needs and expectations in order to develop highly usable web recourses. The purpose of this paper is to outline a multi-case research project focused on the development and evaluation of person-centred web-based support for people with long-term illness. To support the underlying idea to move beyond the illness, we approach the development of web support from the perspective of the emergent area of person-centred care. The project aims to contribute to the ongoing development of web-based supports in health care and to the emerging field of person-centred care. The research design uses a meta-analytical approach through its focus on synthesizing experiences from four Swedish regional and national cases of design and use of web-based support in long-term illness. The cases include children (bladder dysfunction and urogenital malformation), young adults (living close to persons with mental illness), and two different cases of adults (women with breast cancer and childbearing women with type 1 diabetes). All of the cases are ongoing, though in different stages of design, implementation, and analysis. This, we argue, will lead to a synthesis of results on a meta-level not yet described. To allow valid comparisons between the four cases we explore and problematize them in relation to four main aspects: 1) The use of people's experiences and needs; 2) The role of use of theories in the design of person-centred web-based supports; 3) The evaluation of the effects of health outcomes for the informants involved and 4) The development of a generic person-centred model for learning and social support for people with long-term illness and their significant others. Person-centred web-based support is a new area and few studies focus on how web-based interventions can contribute to the development of person-centred care. In

    2006-02-21

    The Web-based Simulation of Patients (Web-SP) project was initiated in order to facilitate the use of realistic and interactive virtual patients (VP) in medicine and healthcare education. Web-SP focuses on moving beyond the technology savvy teachers, when integrating simulation-based education into health sciences curricula, by making the creation and use of virtual patients easier. The project strives to provide a common generic platform for design/creation, management, evaluation and sharing of web-based virtual patients. The aim of this study was to evaluate if it was possible to develop a web-based virtual patient case simulation environment where the entire case authoring process might be handled by teachers and which would be flexible enough to be used in different healthcare disciplines. The Web-SP system was constructed to support easy authoring, management and presentation of virtual patient cases. The case authoring environment was found to facilitate for teachers to create full-fledged patient cases without the assistance of computer specialists. Web-SP was successfully implemented at several universities by taking into account key factors such as cost, access, security, scalability and flexibility. Pilot evaluations in medical, dentistry and pharmacy courses shows that students regarded Web-SP as easy to use, engaging and to be of educational value. Cases adapted for all three disciplines were judged to be of significant educational value by the course leaders. The Web-SP system seems to fulfil the aim of providing a common generic platform for creation, management and evaluation of web-based virtual patient cases. The responses regarding the authoring environment indicated that the system might be user-friendly enough to appeal to a majority of the academic staff. In terms of implementation strengths, Web-SP seems to fulfil most needs from course directors and teachers from various educational institutions and disciplines. The system is currently in

    Technologies that are set to increase the productivity of agricultural practices require more and more data. Nevertheless, farming data is also being increasingly cheap to collect and maintain. Bulk of data that are collected by the sensors and samples need to be analysed in an efficient and transparent manner. Web technologies have long being used to develop applications that can assist the farmers and managers. However until recently, analysing the data in an online environment has not been an easy task especially in the eyes of data analysts. This barrier is now overcome by the availability of new application programming interfaces that can provide real-time web based data analysis. In this paper developing a prototype web based application for data analysis using new facilities in R statistical package and its web development facility, Shiny is explored. The pros and cons of this type of data analysis environment for precision farming are enumerated and future directions in web application development for agricultural data are discussed.

    Full Text Available This research work presents a large-scale study of the problems in real-world web applications and widely-used mobile browsers. Through a large-scale experiment, we find inconsistencies in Secure Socket Layer (SSL warnings among popular mobile web browsers (over a billion users download. The majority of popular mobile browsers on the Google Play Store either provide incomplete information in SSL warnings shown to users or failed to provide SSL warnings in the presence of security certificate errors, thus making it a difficult task even for a security savvy user to make an informed decision. In addition, we find that 28% of websites are using mixed content. Mixed content means a secure website (https loads a sub resource using insecure HTTP protocol. The mixed content weakens the security of entire website and vulnerable to man-in-the-middle (MITM attacks. Furthermore, we inspected the default behavior of mobile web browsers and report that majority of mobile web browsers allow execution of mixed content in web applications, which implies billions of mobile browser users are vulnerable to eavesdropping and MITM attacks. Based on our findings, we make recommendations for website developers, users and browser vendors.

    2008-04-01

    Full Text Available With the vast development of various technologies, learning today is no longer confined to classrooms with lecture delivery as the only method of conveying knowledge, rather, an electronic means of learning has continued to evolve. Electronic learning (e-Learning, which facilitates education using communications networks, has made learning possible from anywhere at anytime using the Internet, wide area networks or local area networks. Notably, e-Learning applications which have now become central to the learning process may be developed using proprietary programming tools and the process of acquiring and using them to develop large software application is not only complex but require a huge sum of money. A viable alternative is to utilize the open source software platform that allows software engineers and institutions the right to reuse, study, distribute and localize to satisfy user’s requirements. This paper provides an overview of e-Learning and the open source domain as well as discusses how open source can be used to speedily realizes the development of an e-Learning application in a web environment using an adaptive process. Specifically, the authors described their preliminary experiment of implementing an open source e-Learning platform by adapting free PHP source code and MySQL database to suit an electronic class bulletin board.

    Scotch, Matthew; Yip, Kevin Y; Cheung, Kei-Hoi

    2008-01-01

    Development of public health informatics applications often requires the integration of multiple data sources. This process can be challenging due to issues such as different file formats, schemas, naming systems, and having to scrape the content of web pages. A potential solution to these system development challenges is the use of Web 2.0 technologies. In general, Web 2.0 technologies are new internet services that encourage and value information sharing and collaboration among individuals. In this case report, we describe the development and use of Web 2.0 technologies including Yahoo! Pipes within a public health application that integrates animal, human, and temperature data to assess the risk of West Nile Virus (WNV) outbreaks. The results of development and testing suggest that while Web 2.0 applications are reasonable environments for rapid prototyping, they are not mature enough for large-scale public health data applications. The application, in fact a "systems of systems," often failed due to varied timeouts for application response across web sites and services, internal caching errors, and software added to web sites by administrators to manage the load on their servers. In spite of these concerns, the results of this study demonstrate the potential value of grid computing and Web 2.0 approaches in public health informatics.

    The web can be regarded as an ecosystem of digital resources connected and shaped by collective successive behaviors of users. Knowing how people allocate limited attention on different resources is of great importance. To answer this, we embed the most popular Chinese web sites into a high dimensional Euclidean space based on the open flow network model of a large number of Chinese users' collective attention flows, which both considers the connection topology of hyperlinks between the sites and the collective behaviors of the users. With these tools, we rank the web sites and compare their centralities based on flow distances with other metrics. We also study the patterns of attention flow allocation, and find that a large number of web sites concentrate on the central area of the embedding space, and only a small fraction of web sites disperse in the periphery. The entire embedding space can be separated into 3 regions(core, interim, and periphery). The sites in the core (1%) occupy a majority of the attention flows (40%), and the sites (34%) in the interim attract 40%, whereas other sites (65%) only take 20% flows. What's more, we clustered the web sites into 4 groups according to their positions in the space, and found that similar web sites in contents and topics are grouped together. In short, by incorporating the open flow network model, we can clearly see how collective attention allocates and flows on different web sites, and how web sites connected each other.

    Dengue fever incidence and its geographical distribution are increasing throughout the world. Quality and timely information is essential for its prevention and control. A web based, geographically enabled, dengue integral surveillance system (Dengue-GIS) was developed for the nation-wide collection, integration, analysis and reporting of geo-referenced epidemiologic, entomologic, and control interventions data. Consensus in the design and practical operation of the system was a key factor for its acceptance. Working with information systems already implemented as a starting point facilitated its acceptance by officials and operative personnel. Dengue-GIS provides the geographical detail needed to plan, asses and evaluate the impact of control activities. The system is beginning to be adopted as a knowledge base by vector control programs. It is used to generate evidence on impact and cost-effectiveness of control activities, promoting the use of information for decision making at all levels of the vector control program. Dengue-GIS has also been used as a hypothesis generator for the academic community. This GIS-based model system for dengue surveillance and the experience gathered during its development and implementation could be useful in other dengue endemic countries and extended to other infectious or chronic diseases.

  4. Integrating video and animation with physics problem- solving exercises on the World Wide Web

    Science.gov (United States)

    Titus, Aaron Patrick

    1998-10-01

    Problem solving is of paramount importance in teaching and learning physics. An important step in solving a problem is visualization. To help students visualize a problem, we included video clips with homework questions delivered via the World Wide Web. Although including video with physics problems has a positive effect with some problems, we found that this may not be the best way to integrate multimedia with physics problems since improving visualization is probably not as helpful as changing students' approach. To challenge how students solve problems and to help them develop a more expert-like approach, we developed a type of physics exercise called a multimedia-focused problem where students take data from an animation in order to solve a problem. Because numbers suggestive of a solution are not given in the text of the question, students have to consider the problem conceptually before analyzing it mathematically. As a result, we found that students had difficulty solving such problems compared to traditional textbook-like problems. Students' survey responses showed that students indeed had difficulty determining what was needed to solve a problem when it was not explicitly given to them in the text of the question. Analyzing think-aloud interviews where students verbalized their thoughts while solving problems, we found that multimedia-focused problems indeed required solid conceptual understanding in order for them to be solved correctly. As a result, we believe that when integrated with instruction, multimedia-focused problems can be a valuable tool in helping students develop better conceptual understanding and more expert-like problem solving skills by challenging novice beliefs and problem solving approaches. Multimedia-focused problems may also be useful for diagnosing conceptual understanding and problem skills.

    Radionuclide sorption data is necessary for the safety assessment of radioactive waste disposal. However the accessibility to the nuclide sorption database is limited. The web-based sorption database (KAERI-SDB) was developed to provide sorption data in a convenient way. The development of the KAERI-SDB was achieved by improving the performance of pre-existing sorption DB programme (SDB-21C) and incorporating the user requirement. The KAERI-SDB was designed that users can access it by using a web browser. Main functions of the KAERI-SDB include (1) log-in/join, (2) search and store of sorption data and (3) scatter plot chart and index chart. It is expected that the KAERI-SDB is widely applied to the safety assessment of radioactive waste disposal by enhancing the accessibility to experts and practitioner related the nuclear industry and governmental administration. It is also expected that reliabilities for the radioactive waste disposal increased by opening the web-based sorption DB to public

    2013-01-01

    Background To reduce the large public health burden of the high prevalence of depression, preventive interventions targeted at people at risk are essential and can be cost-effective. Web-based interventions are able to provide this care, but there is no agreement on how to best develop these applications and often the technology is seen as a given. This seems to be one of the main reasons that web-based interventions do not reach their full potential. The current study describes the development of a web-based intervention for the indicated prevention of depression, employing the CeHRes (Center for eHealth Research and Disease Management) roadmap. The goals are to create a user-friendly application which fits the values of the stakeholders and to evaluate the process of development. Methods The employed methods are a literature scan and discussion in the contextual inquiry; interviews, rapid prototyping and a requirement session in the value specification stage; and user-based usability evaluation, expert-based usability inspection and a requirement session in the design stage. Results The contextual inquiry indicated that there is a need for easily accessible interventions for the indicated prevention of depression and web-based interventions are seen as potentially meeting this need. The value specification stage yielded expected needs of potential participants, comments on the usefulness of the proposed features and comments on two proposed designs of the web-based intervention. The design stage yielded valuable comments on the system, content and service of the web-based intervention. Conclusions Overall, we found that by developing the technology, we successfully (re)designed the system, content and service of the web-based intervention to match the values of stakeholders. This study has shown the importance of a structured development process of a web-based intervention for the indicated prevention of depression because: (1) it allows the development team to

    The thermal models used for analyzing dendritic web growth and calculating the thermal stress were reexamined to establish the validity limits imposed by the assumptions of the models. Also, the effects of thermal conduction through the gas phase were evaluated and found to be small. New growth designs, both static and dynamic, were generated using the modeling results. Residual stress effects in dendritic web were examined. In the laboratory, new techniques for the control of temperature distributions in three dimensions were developed. A new maximum undeformed web width of 5.8 cm was achieved. A 58% increase in growth velocity of 150 micrometers thickness was achieved with dynamic hardware. The area throughput goals for transient growth of 30 and 35 sq cm/min were exceeded.

  16. Overcoming Legal Limitations in Disseminating Slovene Web Corpora

    Directory of Open Access Journals (Sweden)

    Tomaž Erjavec

    2016-09-01

    Full Text Available Web texts are becoming increasingly relevant sources of information, with web corpora useful for corpus linguistic studies and development of language technologies. Even though web texts are directly accessable, which substantially simplifies the collection procedure compilation of web corpora is still complex, time consuming and expensive. It is crucial that similar endeavours are not repeated, which is why it is necessary to make the created corpora easily and widely accessible both to researchers and a wider audience. While this is logistically and technically a straightforward procedure, legal constraints, such as copyright, privacy and terms of use severely hinder the dissemination of web corpora. This paper discusses legal conditions and actual practice in this area, gives an overview of current practices and proposes a range of mitigation measures on the example of the Janes corpus of Slovene user-generated content in order to ensure free and open dissemination of Slovene web corpora.

  18. Using Web-Based Knowledge Extraction Techniques to Support Cultural Modeling

    Science.gov (United States)

    Smart, Paul R.; Sieck, Winston R.; Shadbolt, Nigel R.

    The World Wide Web is a potentially valuable source of information about the cognitive characteristics of cultural groups. However, attempts to use the Web in the context of cultural modeling activities are hampered by the large-scale nature of the Web and the current dominance of natural language formats. In this paper, we outline an approach to support the exploitation of the Web for cultural modeling activities. The approach begins with the development of qualitative cultural models (which describe the beliefs, concepts and values of cultural groups), and these models are subsequently used to develop an ontology-based information extraction capability. Our approach represents an attempt to combine conventional approaches to information extraction with epidemiological perspectives of culture and network-based approaches to cultural analysis. The approach can be used, we suggest, to support the development of models providing a better understanding of the cognitive characteristics of particular cultural groups.

    Full Text Available Abstract Background The Web-based Simulation of Patients (Web-SP project was initiated in order to facilitate the use of realistic and interactive virtual patients (VP in medicine and healthcare education. Web-SP focuses on moving beyond the technology savvy teachers, when integrating simulation-based education into health sciences curricula, by making the creation and use of virtual patients easier. The project strives to provide a common generic platform for design/creation, management, evaluation and sharing of web-based virtual patients. The aim of this study was to evaluate if it was possible to develop a web-based virtual patient case simulation environment where the entire case authoring process might be handled by teachers and which would be flexible enough to be used in different healthcare disciplines. Results The Web-SP system was constructed to support easy authoring, management and presentation of virtual patient cases. The case authoring environment was found to facilitate for teachers to create full-fledged patient cases without the assistance of computer specialists. Web-SP was successfully implemented at several universities by taking into account key factors such as cost, access, security, scalability and flexibility. Pilot evaluations in medical, dentistry and pharmacy courses shows that students regarded Web-SP as easy to use, engaging and to be of educational value. Cases adapted for all three disciplines were judged to be of significant educational value by the course leaders. Conclusion The Web-SP system seems to fulfil the aim of providing a common generic platform for creation, management and evaluation of web-based virtual patient cases. The responses regarding the authoring environment indicated that the system might be user-friendly enough to appeal to a majority of the academic staff. In terms of implementation strengths, Web-SP seems to fulfil most needs from course directors and teachers from various educational

    To develop a platform that uses structured reporting templates according to the IHE Management of Radiology Report Templates (MRRT) profile, and to implement this platform into clinical routine. The reporting platform uses standard web technologies (HTML / JavaScript and PHP / MySQL) only. Several freely available external libraries were used to simplify the programming. The platform runs on a standard web server, connects with the radiology information system (RIS) and PACS, and is easily accessible via a standard web browser. A prototype platform that allows structured reporting to be easily incorporated into the clinical routine was developed and successfully tested. To date, 797 reports were generated using IHE MRRT-compliant templates (many of them downloaded from the RSNA's radreport.org website). Reports are stored in a MySQL database and are easily accessible for further analyses. Development of an IHE MRRT-compliant platform for structured reporting is feasible using only standard web technologies.

    Full Text Available Stress placed on network infrastructure by the popularity of the World Wide Web may be partially relieved by keeping multiple copies of Web documents at geographically dispersed locations. In particular, use of proxy caches and replication provide a means of storing information 'nearer to end users'. This paper concentrates on the locational aspects of Web caching giving both an overview, from an operational research point of view, of existing research and putting forward avenues for possible further research. This area of research is in its infancy and the emphasis will be on themes and trends rather than on algorithm construction. Finally, Web caching problems are briefly related to referral systems more generally.

    The World Wide Web is an extremely powerful source of information, inspiration, ideas, and opportunities. As such, it has become an integral part of daily life for a great majority of people. Yet, for a significant number of others, the internet offers only limited value due to the existence of barriers which make accessing the Web difficult, if not impossible. This article illustrates some of the reasons that achieving equality of access to the online world of education is so critical, explores the current status of Web accessibility, discusses evaluative tools and methods that can help identify accessibility issues in educational websites, and provides practical recommendations and guidelines for resolving some of the obstacles that currently hinder the achievability of the goal of universal Web access.

    1974-01-01

    An advanced composite web concept was developed for potential application to the Space Shuttle Orbiter main engine thrust structure. The program consisted of design synthesis, analysis, detail design, element testing, and large scale component testing. A concept was sought that offered significant weight saving by the use of Boron/Epoxy (B/E) reinforced titanium plate structure. The desired concept was one that was practical and that utilized metal to efficiently improve structural reliability. The resulting development of a unique titanium-clad B/E shear web design concept is described. Three large scale components were fabricated and tested to demonstrate the performance of the concept: a titanium-clad plus or minus 45 deg B/E web laminate stiffened with vertical B/E reinforced aluminum stiffeners.

    Purpose The intrasaccular flow disruptor Woven EndoBridge (WEB) device is developed for the treatment of wide-necked aneurysms without supportive devices. We used the WEB as primary treatment for unruptured aneurysms suitable for the device, regardless of neck size. Methods Between February 2015 and June 2017, 59 aneurysms in 51 patients were selectively treated with the WEB. There were 15 men and 36 women with a mean age of 59 years. Mean aneurysm size was 7.0 mm (range 3-22 mm). Of 59 aneurysms, 45 (76%) had a wide neck defined as ≥4 mm or dome-neck ratio ≤1.5. No stents or supporting balloons were used. Results Initial WEB position was judged good in all 59 unruptured aneurysms. One patient with a basilar tip aneurysm had a late thrombotic posterior cerebral artery occlusion by protrusion of the WEB over the artery. There were no procedural ruptures. Overall complication rate was 2.0% (1 of 51, 95% CI 0.01-11.3%). Imaging follow-up was available in 55 of 59 aneurysms (93%). At 3 months, 41 of 57 aneurysms (72%) were completely occluded, 12 (21%) had a neck remnant and 4 (7%) were incompletely occluded. Conclusion WEB treatment is safe and effective in selected unruptured aneurysms suitable for the device, regardless of neck size or location. There was no need for supportive devices. Three-quarters of all unruptured small aneurysms could be treated with the WEB. In our opinion, the WEB is a valuable alternative to coils, especially in wide-necked aneurysms.

    Web Engineering is the application of systematic, disciplined and quantifiable approaches to development, operation, and maintenance of Web-based applications. It is both a pro-active approach and a growing collection of theoretical and empirical research in Web application development. This paper gives an overview of Web Engineering by addressing the questions: (a) why is it needed? (b) what is its domain of operation? (c) how does it help and what should it do to improve Web application development? and (d) how should it be incorporated in education and training? The paper discusses the significant differences that exist between Web applications and conventional software, the taxonomy of Web applications, the progress made so far and the research issues and experience of creating a specialization at the master's level. The paper reaches a conclusion that Web Engineering at this stage is a moving target since Web technologies are constantly evolving, making new types of applications possible, which in turn may require innovations in how they are built, deployed and maintained.

    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. 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. 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. 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.

    2004-03-01

    Full Text Available Abstract Background Very often genome-wide data analysis requires the interoperation of multiple databases and analytic tools. A large number of genome databases and bioinformatics applications are available through the web, but it is difficult to automate interoperation because: 1 the platforms on which the applications run are heterogeneous, 2 their web interface is not machine-friendly, 3 they use a non-standard format for data input and output, 4 they do not exploit standards to define application interface and message exchange, and 5 existing protocols for remote messaging are often not firewall-friendly. To overcome these issues, web services have emerged as a standard XML-based model for message exchange between heterogeneous applications. Web services engines have been developed to manage the configuration and execution of a web services workflow. Results To demonstrate the benefit of using web services over traditional web interfaces, we compare the two implementations of HAPI, a gene expression analysis utility developed by the University of California San Diego (UCSD that allows visual characterization of groups or clusters of genes based on the biomedical literature. This utility takes a set of microarray spot IDs as input and outputs a hierarchy of MeSH Keywords that correlates to the input and is grouped by Medical Subject Heading (MeSH category. While the HTML output is easy for humans to visualize, it is difficult for computer applications to interpret semantically. To facilitate the capability of machine processing, we have created a workflow of three web services that replicates the HAPI functionality. These web services use document-style messages, which means that messages are encoded in an XML-based format. We compared three approaches to the implementation of an XML-based workflow: a hard coded Java application, Collaxa BPEL Server and Taverna Workbench. The Java program functions as a web services engine and interoperates

    2016-06-01

    To objectively assess the quality of information available on the World Wide Web on cardiac resynchronization therapy (CRT). Patients frequently search the internet regarding their healthcare issues. It has been shown that patients seeking information can help or hinder their healthcare outcomes depending on the quality of information consulted. On the internet, this information can be produced and published by anyone, resulting in the risk of patients accessing inaccurate and misleading information. The search term "Cardiac Resynchronisation Therapy" was entered into the three most popular search engines and the first 50 pages on each were pooled and analyzed, after excluding websites inappropriate for objective review. The "LIDA" instrument (a validated tool for assessing quality of healthcare information websites) was to generate scores on Accessibility, Reliability, and Usability. Readability was assessed using the Flesch Reading Ease Score (FRES). Of the 150 web-links, 41 sites met the eligibility criteria. The sites were assessed using the LIDA instrument and the FRES. A mean total LIDA score for all the websites assessed was 123.5 of a possible 165 (74.8%). The average Accessibility of the sites assessed was 50.1 of 60 (84.3%), on Usability 41.4 of 54 (76.6%), on Reliability 31.5 of 51 (61.7%), and 41.8 on FRES. There was a significant variability among sites and interestingly, there was no correlation between the sites' search engine ranking and their scores. This study has illustrated the variable quality of online material on the topic of CRT. Furthermore, there was also no apparent correlation between highly ranked, popular websites and their quality. Healthcare professionals should be encouraged to guide their patients toward the online material that contains reliable information. © 2016 Wiley Periodicals, Inc.

    2008-01-01

    Despite being the sum of decentralized and uncoordinated efforts by heterogeneous groups and individuals, the World Wide Web exhibits a well-defined structure, characterized by several interesting properties. This structure was clearly revealed by Broder et al (2000 Graph structure in the web Comput. Netw. 33 309) who presented the evocative bow-tie picture of the Web. Although, the bow-tie structure is a relatively clear abstraction of the macroscopic picture of the Web, it is quite uninformative with respect to the finer details of the Web graph. In this paper, we mine the inner structure of the Web graph. We present a series of measurements on the Web, which offer a better understanding of the individual components of the bow-tie. In the process, we develop algorithmic techniques for performing these measurements. We discover that the scale-free properties permeate all the components of the bow-tie which exhibit the same macroscopic properties as the Web graph itself. However, close inspection reveals that their inner structure is quite distinct. We show that the Web graph does not exhibit self similarity within its components, and we propose a possible alternative picture for the Web graph, as it emerges from our experiments

    Easy to use, interactive, and platform-independent WWW-based tools are ideal for development of chemical applications. By using the newly emerging Web technologies such as Java applets and sophisticated scripting, it is possible to deliver powerful molecular processing capabilities directly to the desk of synthetic organic chemists. In Novartis Crop Protection in Basel, a Web-based molecular modelling system has been in use since 1995. In this article two new modules of this system are presented: a program for interactive calculation of important hydrophobic, electronic, and steric properties of organic substituents, and a module for substituent similarity searches enabling the identification of bioisosteric functional groups. Various possible applications of calculated substituent parameters are also discussed, including automatic design of molecules with the desired properties and creation of targeted virtual combinatorial libraries.

    Full Text Available Semantic Web approaches try to get the interoperability and communication among technologies and organizations. Nevertheless, sometimes it is forgotten that the Web must be useful for every user, consequently it is necessary to include tools and techniques doing Semantic Web be accessible. Accessibility and usability are two usually joined concepts widely used in web application development, however their meaning are different. Usability means the way to make easy the use but accessibility is referred to the access possibility. For the first one, there are many well proved approaches in real cases. However, accessibility field requires a deeper research that will make feasible the access to disable people and also the access to novel non-disable people due to the cost to automate and maintain accessible applications. In this paper, we propose one architecture to achieve the accessibility in web-environments dealing with the WAI accessibility standard and the Universal Design paradigm. This architecture tries to control the accessibility in web applications development life-cycle following a methodology starting from a semantic conceptual model and leans on description languages and controlled vocabularies.

    Implementation of learning on food analysis course in Program Study of Agro-industrial Technology Education faced problems. These problems include the availability of space and tools in the laboratory that is not comparable with the number of students also lack of interactive learning tools. On the other hand, the information technology literacy of students is quite high as well the internet network is quite easily accessible on campus. This is a challenge as well as opportunities in the development of learning media that can help optimize learning in the laboratory. This study aims to develop web-based virtual laboratory as one of the alternative learning media in food analysis course. This research is R & D (research and development) which refers to Borg & Gall model. The results showed that assessment’s expert of web-based virtual labs developed, in terms of software engineering aspects; visual communication; material relevance; usefulness and language used, is feasible as learning media. The results of the scaled test and wide-scale test show that students strongly agree with the development of web based virtual laboratory. The response of student to this virtual laboratory was positive. Suggestions from students provided further opportunities for improvement web based virtual laboratory and should be considered for further research.

    With the development of inexpensive, high-throughput sequencing technologies, it has become feasible to examine questions related to population genetics and molecular evolution of non-model species in their ecological contexts on a genome-wide scale. Here, we employed a newly developed suite of integrated, web-based programs to examine population dynamics and signatures of selection across the genome using several well-established tests, including F ST, pN/pS, and McDonald-Kreitman. We applied these techniques to study populations of honey bees (Apis mellifera) in East Africa. In Kenya, there are several described A. mellifera subspecies, which are thought to be localized to distinct ecological regions. We performed whole genome sequencing of 11 worker honey bees from apiaries distributed throughout Kenya and identified 3.6 million putative single-nucleotide polymorphisms. The dense coverage allowed us to apply several computational procedures to study population structure and the evolutionary relationships among the populations, and to detect signs of adaptive evolution across the genome. While there is considerable gene flow among the sampled populations, there are clear distinctions between populations from the northern desert region and those from the temperate, savannah region. We identified several genes showing population genetic patterns consistent with positive selection within African bee populations, and between these populations and European A. mellifera or Asian Apis florea. These results lay the groundwork for future studies of adaptive ecological evolution in honey bees, and demonstrate the use of new, freely available web-based tools and workflows ( http://usegalaxy.org/r/kenyanbee ) that can be applied to any model system with genomic information.

    Full Text Available Web-based learning (WBL has been widely implemented in various educational settings as a learning medium but there is a doubt about its superiority over text or lecture-based, teacher centered traditional education because of inconclusive findings in the related research. The purpose of this study was to examine the effects of WBL on the teacher candidates’ content acquisition in a pedagogical course and on their attitudes toward this we-based course. Post-test only experimental study was conducted in a vocational teacher education program in Turkey. In the experimental group, WBL was conducted for three weeks for three topics: cognitive, moral and personality development and in the control group, lecture-based traditional teaching methods were applied. An achievement test was administered to both groups at the end of the study. According to the results, the groups did not show difference. In addition, the results of the attitude scale revealed that the students in the experimental group, on the average, had positive perceptions toward the web environment, web-based course, course instructor, course assessment, and success in the course. This result pointed out that though the impact of WBL on the acquisition of course topics did not differ between the groups, its positive impact on the students’ impression about teaching-learning process of the course, instructor and course assessment should not be ignored. Within the scope of this study, the results implied that WBL in teacher education might be applied in order to provide better learning environment rather than better knowledge gain.

    Java is a programming language that runs on a "virtual machine" built into World Wide Web (WWW)-browsing programs on multiple hardware platforms. Web pages were developed with Java to enable Web-browsing programs to overlay transparent graphics and text on displayed images so that the user could control the display of labels and annotations on the images, a key feature not available with standard Web pages. This feature was extended to include the presentation of normal radiologic anatomy. Java programming was also used to make Web browsers compatible with the Digital Imaging and Communications in Medicine (DICOM) file format. By enhancing the functionality of Web pages, Java technology should provide greater incentive for using a Web-based approach in the development of radiology teaching material.

    Advertising on the World Wide Web is based around automatically matching web pages with appropriate advertisements, in the form of banner ads, interactive adverts, or text links. Traditionally this has been done by manual classification of pages, or more recently using information retrieval techniques to find the most important keywords from the page, and match these to keywords being used by adverts. In this paper, we propose a new model for online advertising, based around lightweight embedded semantics. This will improve the relevancy of adverts on the World Wide Web and help to kick-start the use of RDFa as a mechanism for adding lightweight semantic attributes to the Web. Furthermore, we propose a system architecture for the proposed new model, based on our scalable ontology reasoning infrastructure TrOWL.

    The creation and maintenance of radiology teaching materials is both laborious and very time-consuming, but at a teaching hospital is important. Through use of the technology offered by today's worldwide web, this problem can be efficiently solved, and on this basis, we devised a multimedia radiology self-learning course for abdominal ultrasound and CT. A combination of video and audio tapes has been used as teaching material; the authors digitized and converted these to Hypertext Mark-up Language (HTML) format. films were digitized with a digital camera and compressed to joint photographic expert group (JPEG) format, while audio tapes were digitized with a sound recorder and compressed to real audio format. Multimedia on the worldwide web will facilitate easy management and maintenance of a self-learning course. To make this more suitable for practical use, continual upgrading on the basis of experience is needed. (author). 3 refs., 4 figs

    The World Wide Web has changed the way people interact. It has also become an important equalizer of information access for many social sectors. However, for many people, including some sign language users, Web accessing can be difficult. For some, it not only presents another barrier to overcome but has left them without cultural equality.

    Open source intelligence (OSINT) and web reconnaissance are rich topics for infosec professionals looking for the best ways to sift through the abundance of information widely available online. In many cases, the first stage of any security assessment-that is, reconnaissance-is not given enough attention by security professionals, hackers, and penetration testers. Often, the information openly present is as critical as the confidential data. Hacking Web Intelligence shows you how to dig into the Web and uncover the information many don't even know exists. The book takes a holistic approach

    Self-management skills are essential for patients with diabetes mellitus to minimise the risks of complications from their condition. The aim of this research was to develop a web-based application for self-management of type 1 diabetes, suitable for use by patients, their carers and physicians. The study was comprised of two phases, the first being analysis of the kind of information and capabilities required by potential users of the system. Based on the results derived from the first phase of the study, the system prototype was designed and then evaluated using the 'think aloud' method and a standard questionnaire. The application was designed for use by patients, their carers and physicians. Patients could enter the level of blood glucose, insulin and activities on a daily basis, and physicians were able to supervise a patient's health status from a distance. Users were generally satisfied with the final version of the system. People with a wide range of literacy skills were able to use the system effectively. Patients or their carers could use the web-based application as a log book by entering the level of blood glucose and insulin doses on a regular basis, and as an educational resource to improve self-management skills. Physicians could use the system at any time convenient to them to support patients by giving medical advice. Further research is needed to report the effectiveness of the system in practice.

    Full Text Available Abstract In todays digital world reliance on the World Wide Web as a source of information is extensive. Users increasingly rely on web based search engines to provide accurate search results on a wide range of topics that interest them. The search engines in turn parse the vast repository of web pages searching for relevant information. However majority of web portals are designed using web templates which are designed to provide consistent look and feel to end users. The presence of these templates however can influence search results leading to inaccurate results being delivered to the users. Therefore to improve the accuracy and reliability of search results identification and removal of web templates from the actual content is essential. A wide range of approaches are commonly employed to achieve this and this paper focuses on the study of the various approaches of template detection and extraction that can be applied across homogenous as well as heterogeneous web pages.

  20. Nation-wide, web-based, geographic information system for the integrated surveillance and control of dengue fever in Mexico.

    Full Text Available Dengue fever incidence and its geographical distribution are increasing throughout the world. Quality and timely information is essential for its prevention and control. A web based, geographically enabled, dengue integral surveillance system (Dengue-GIS was developed for the nation-wide collection, integration, analysis and reporting of geo-referenced epidemiologic, entomologic, and control interventions data. Consensus in the design and practical operation of the system was a key factor for its acceptance. Working with information systems already implemented as a starting point facilitated its acceptance by officials and operative personnel. Dengue-GIS provides the geographical detail needed to plan, asses and evaluate the impact of control activities. The system is beginning to be adopted as a knowledge base by vector control programs. It is used to generate evidence on impact and cost-effectiveness of control activities, promoting the use of information for decision making at all levels of the vector control program. Dengue-GIS has also been used as a hypothesis generator for the academic community. This GIS-based model system for dengue surveillance and the experience gathered during its development and implementation could be useful in other dengue endemic countries and extended to other infectious or chronic diseases.
