Methods for the design and administration of web-based surveys.

This paper describes the design, development, and administration of a Web-based survey to determine the use of the Internet in clinical practice by 450 dental professionals. The survey blended principles of a controlled mail survey with data collection through a Web-based database application. The survey was implemented as a series of simple HTML pages and tested with a wide variety of operating environments. The response rate was 74.2 percent. Eighty-four percent of the participants completed the Web-based survey, and 16 percent used e-mail or fax. Problems identified during survey administration included incompatibilities/technical problems, usability problems, and a programming error. The cost of the Web-based survey was 38 percent less than that of an equivalent mail survey. A general formula for calculating breakeven points between electronic and hardcopy surveys is presented. Web-based surveys can significantly reduce turnaround time and cost compared with mail surveys and may enhance survey item completion rates.

Bringing chemical data onto the Semantic Web.

Present chemical data storage methodologies place many restrictions on the use of the stored data. The absence of sufficient high-quality metadata prevents intelligent computer access to the data without human intervention. This creates barriers to the automation of data mining in activities such as quantitative structure-activity relationship modelling. The application of Semantic Web technologies to chemical data is shown to reduce these limitations. The use of unique identifiers and relationships (represented as uniform resource identifiers, URIs, and resource description framework, RDF) held in a triplestore provides for greater detail and flexibility in the sharing and storage of molecular structures and properties.

Guidelines for designing a Web-delivered college health risk behavior survey: lessons learned from the University of Florida Health Behavior Survey.

Collecting health-risk behavior data from college students is a Web survey research application with extraordinary potential that has implications for individual schools and for the next National College Health Risk Behavior Survey. Recent evidence suggests that it is now feasible to collect health-risk behavior data from college students using the Web. This article describes the eight steps used in the 1999 University of Florida Health Behavior Survey that demonstrated the feasibility of the Web to collect health-risk behavior data from undergraduates. Practical issues researchers should consider when conducting Web-delivered survey research also are presented. Information in this article can be used by college and university health survey researchers and student health service administrators to plan and conduct their own health-risk behavior Web-delivered survey, and to develop an electronic college health-risk behavior surveillance system for their schools.

Teaching resources for dermatology on the WWW--quiz system and dynamic lecture scripts using a HTTP-database demon.

The World Wide Web (WWW) is becoming the major way of acquiring information in all scientific disciplines as well as in business. It is very well suitable for fast distribution and exchange of up to date teaching resources. However, to date most teaching applications on the Web do not use its full power by integrating interactive components. We have set up a computer based training (CBT) framework for Dermatology, which consists of dynamic lecture scripts, case reports, an atlas and a quiz system. All these components heavily rely on an underlying image database that permits the creation of dynamic documents. We used a demon process that keeps the database open and can be accessed using HTTP to achieve better performance and avoid the overhead involved by starting CGI-processes. The result of our evaluation was very encouraging.

Building an application framework for integrative genomics.

The accelerated pace of biological research and the current availability of whole-genome data sets provides significant new sources of functional insight. We designed an architecture and framework for software to query and explore such data in an orderly and iterative fashion. The architecture is intended to provide an extensible platform for developing web based bioinformatics applications and to offer a flexible and end-user-extensible software environment to explore and integrate disparate biological data sources. This will enable the user to explore existing relationships and discover new functional relationships among these data.

A multi-layered application for the gross description using Semantic Web technology.

OBJECTIVE: Development of a Semantic Web technology based system for the formalization of the gross description. METHOD: A system is developed using the Java-2 platform. It is based on a light-weight version of the Galen top level ontology. Web technologies like XML, SAX en DOM have been used. RESULT: Three system components have been developed to support the semantic, the object and the syntax layers of the PathOnt architecture. CONCLUSION: The PathOnt approach provides a tool for the communication among clinicians and technicians involved in pathology examinations. This tool also provides a foundation for linking the specimen-specific data with the controlled medical ontology so that the stored information can be used in different circumstances.

Developing Online Communities with LAMP (Linux, Apache, MySQL, PHP) - the IMIA OSNI and CHIRAD Experiences.

Many health informatics organisations do not seem to use, on a practical basis, for the benefit of their activities and interaction with their members, the very technologies that they often promote for use within healthcare environments. In particular, many organisations seem to be slow to take up the benefits of interactive web technologies. This paper presents an introduction to some of the many free/libre and open source (FLOSS) applications currently available and using the LAMP - Linux, Apache, MySQL, PHP architecture - as a way of cheaply deploying reliable, scalable, and secure web applications. The experience of moving to applications using LAMP architecture, in particular that of the Open Source Nursing Informatics (OSNI) Working Group of the Special Interest Group in Nursing Informatics of the International Medical Informatics Association (IMIA-NI), in using PostNuke, a FLOSS Content Management System (CMS) illustrates many of the benefits of such applications. The experiences of the authors in installing and maintaining a large number of websites using FLOSS CMS to develop dynamic, interactive websites that facilitate real engagement with the members of IMIA-NI OSNI, the IMIA Open Source Working Group, and the Centre for Health Informatics Research and Development (CHIRAD), as well as other organisations, is used as the basis for discussing the potential benefits that could be realised by others within the health informatics community.

Classification of the first web space free flap of the foot and its applications in reconstruction of the hand.

Owing to its unique anatomic arterial supply and dual nerve innervation, the first web space of the foot can be used to harvest various sizes and shapes of flaps, which the authors have classified into four types according to their usage in hand reconstruction. This in turn depends on the site, shape, and size of the soft-tissue defect in the hand. Web skin flaps (n = 8) were used in prevention of contracture in the first web space and for proximal finger reconstruction. Two-island skin flaps (n = 4) were used to resurface the pulp defect in two adjacent fingers. In severe adduction contracture of the first web space, fill-up web flaps (n = 10) were used to replace the volume defect after a release procedure in the hand. Adjuvant web flaps (n = 9) were used in wrap-around procedures, in dorsalis pedis flap transfer, and in vascularized joint transfer to supplement the main flaps and to restore sensation in the reconstructed area. In the past 10 years up to February of 1998, a total of 31 patients with soft-tissue defects in the hand and fingers were reconstructed using the web space free flap with flap survival rate of 100 percent. The mean static 2-point discrimination was 8.5 (7.2 to 10) mm, and the mean first web angle was 86 degrees. The advantage of the first web space flap from the foot is that it can easily be harvested to match various sizes and shapes of defects in the hand and fingers. In addition, because of the anatomic similarity in contour, thickness, texture, and nerve innervation with the hand, the sensory restoration is excellent with minimal morbidity at the donor site. By classifying the flaps into four types according to various sizes, shapes, and the site from which the flap are harvested, clinical usefulness in various types of hand and finger reconstruction was confirmed.

SynFlow: an interactive online genome structural variant viewer.

MOTIVATION: Structural variations (SVs), including inversions, translocations (TRAs), duplications, and large insertions or deletions, are key drivers of genome evolution and phenotypic diversity. With the increasing number of high-quality, chromosome-scale genome assemblies, the ability to detect and interpret SVs has become a crucial aspect of modern genomics. While SV detection has advanced, most visualization methods produce static plots that fall short when researchers, particularly in comparative genomics, need to interactively explore large datasets, zoom into specific genomic regions, or dynamically filter structural events in real time. RESULTS: To address this gap, we introduce SynFlow, a lightweight, web-based interactive application specifically designed for exploring and visualizing SVs identified by SyRI. We demonstrate that SynFlow can reproduce complex static synteny plots published in literature, but transforms them into dynamic, shareable visualizations that support real-time filtering, reordering, and deep exploration of specific SVs, including TRAs. SynFlow is available as a web server and offers multiple entry points: browsing precomputed datasets (e.g. banana and grapevine genomes), uploading user-provided SyRI outputs, or running an integrated workflow to produce and visualize SVs on the fly. AVAILABILITY AND IMPLEMENTATION: https://synflow.southgreen.fr; source code https://github.com/SouthGreenPlatform/synflow; preprocessing Snakemake workflow https://gitlab.cirad.fr/agap/cluster/snakemake/synflow.

Potential for meeting clinician information requirements in an intensive care unit (ICU) via the web.

OBJECTIVE: A web interface allows ICU-oriented information to be accessed from other patient care areas and clinical applications, optimizing information integration in the hospital. In preparation for installation of a web-enabled bedside patient charting application, we attempted to maximize the percentage of our ICU-information requirements that could be met via the web and designed a web interface for accessing this information. DESIGN: A comprehensive inventory of the information needs of our ICU was made by taking an inventory of existing paper and electronic documents, manuals, handouts, patient chart elements, and clinician communication about patients. We then designed a web site, created web-based prototype applications, and linked to hospital web applications. MEASUREMENTS: Before and after implementation of the web site, each category of requirements that were identified were marked as available, partially available, or unavailable via the web. RESULTS: After implementation of the ICU web site, 56.3% of identified information category requirements (+18.3%) were available via the web, 23.9% were partially available (+4.2%) and 19.8% were still unavailable (-22.5%). Implementation of the web-enabled bedside charting application would increase the percentage of information categories available via the web to 73.2% (+16.9%) and 18.3% of required information would be partially web-accessible. CONCLUSIONS: The majority of information required by clinicians in an ICU can be made accessible via the web if a systematic approach is taken to identify needs and to develop or link to applications and web pages to meet these needs.

Tsbrowse: an interactive browser for ancestral recombination graphs.

SUMMARY: Ancestral recombination graphs (ARGs) represent the interwoven paths of genetic ancestry of a set of recombining sequences. The ability to capture the evolutionary history of samples makes ARGs valuable in a wide range of applications in population and statistical genetics. ARG-based approaches are increasingly becoming a part of genetic data analysis pipelines due to breakthroughs enabling ARG inference at biobank-scale. However, there is a lack of visualization tools, which are crucial for validating inferences and generating hypotheses. We present tsbrowse, an open-source, web-based Python application for the interactive visualization of the fundamental building blocks of ARGs, i.e. nodes, edges and mutations. We demonstrate the application of tsbrowse to various data sources and scenarios, and highlight its key features of browsability along the genome, user interactivity, and scalability to very large sample sizes. AVAILABILITY AND IMPLEMENTATION: Tsbrowse is installed as a Python package from PyPI (https://pypi.org/project/tsbrowse/), while a development version is maintained at https://github.com/tskit-dev/tsbrowse. Documentation is available at https://tskit.dev/tsbrowse/docs/. Source code is archived on Zenodo with DOI, https://doi.org/10.5281/zenodo.15683039.

Further application of VM-plasty.

The use of VM-plasty in the repair of web contracture and its application for other regions are presented. We refined VM-plasty so that both ends remain in the "dog ear" form, eschewing the conventional excision and instead making flaps that are set in a zigzag shape. This procedure results in an increase in the effect of extension to the lateral direction, in addition to preventing recontracture. This method is used not only to repair finger web contracture but also for other contracted scars. No recontracture has been observed, and good results have been obtained.

The telematic network of referee hospital "V. Monaldi" in Naples: state of the art and perspectives.

The new advances in I.T. both in Hardware (wideband network) and in Software are rapidly changing the Health Information Systems scenario. In many hospitals of Campania Region this leads in many case to rebuild, starting from zero, both infrastructure and applications. Ericsson Enterprise has recently developed for the A.O. Monaldi and Integrated information System which consists of an advanced LAN (Local Area Network), a number of software infrastructures and some application systems as WEB site, Dicom PACS, E-mail server, Streaming Video from Operating Theatres, Internal TV Network. This integrated system represents the starting point for modern health information systems, which is compliant with new standards. The start-up of such systems represents always a problem for the organization and management point of view, therefore a number of problems concerning: training, education, security, privacy, operative procedures, co-ordination with existing applications, system management at the start-up and after. This paper deals with the technical aspects of this information system and discusses the problem met in introducing these IT products in a big and important hospital of Campania Region in Italy, in order to suggest a model, useful for other similar experiences.

Enhancing traditional, televised, and videotaped courses with Web-based technologies: a comparison of student satisfaction.

BACKGROUND: Varied distance learning strategies can be used to deliver nursing courses, including interactive television, videotape, and Web-based approaches. PURPOSES: (1) To assess student assess student satisfaction with a critical care elective course offered simultaneously via traditional and distance learning formats in which Web-based strategies were added, and (2) to compare satisfaction of students taking the traditional course versus those taking the class via distance technology. METHODS: Students (n = 113) who took the course during the spring 1998 and 1999 semesters completed a teacher-constructed evaluation at the end of the semester. FINDINGS: Mean ratings on the evaluation were positive. Ratings of interaction, communication with instructor, and facilitation of learning were higher from students who took the traditional course. CONCLUSIONS: The application of Web-based technologies may be one factor for the overall course satisfaction. However, it is important to continue to evaluate strategies that work best for students taking courses via distance technology.

Structural exon database, SEDB, mapping exon boundaries on multiple protein structures.

UNLABELLED: Comparative analysis of exon/intron organization of genes and their resulting protein structures is important for understanding evolutionary relationships between species, rules of protein organization and protein functionality. We present Structural Exon Database (SEDB), with a Web interface, an application that allows users to retrieve the exon/intron organization of genes and map the location of the exon boundaries and the intron phase onto a multiple structural alignment. SEDB is linked with Friend, an integrated analytical multiple sequence/structure viewer, which allows simultaneous visualization of exon boundaries on structure and sequence alignments. With SEDB researchers can study the correlations of gene structure with the properties of the encoded three-dimensional protein structures across eukaryotic organisms. AVAILABILITY: SEDB is publicly available at http://glinka.bio.neu.edu/SEDB/SEDB.html SUPPLEMENTARY INFORMATION: On the SEDB Web site.
