Analytical Result

The increased dependency on the World Wide Web by both laboratories and their customers has led LIMS developers to take advantage of thin-client web applications that provide both remote data entry and manipulation, along with remote reporting functionality. Use of an LIMS through a web browser allows a person to interact with a distant application, providing both remote administration and real-time analytical result delivery from virtually anywhere in the world. While there are many benefits of web-based LIMS applications, some concern must be given to these new methods of system architecture before justifying them as a suitable replacement for their traditional client-server systems. Developers and consumers alike must consider the security aspects of introducing a wide area network capable system into a production environment, as well as the concerns of data integrity and usability.

It is generally observed throughout the world that in the last two decades, while the average speed of computers has almost doubled in a span of around eighteen months, the average speed of the network has doubled merely in a span of just eight months! In order to improve the performance, more and more researchers are focusing their research in the field of computers and its related technologies. Internet is one such technology that plays a major role in simplifying the information sharing and retrieval. World Wide Web (WWW) is one such service provided by the Internet. It acts as a medium for sharing of information. As a result, millions of applications run on the Internet and cause increased network traffic and put a great demand on the available network infrastructure.

With the ubiquitous availability of browsers and internet access, the last few years have seen a tremendous growth in the number of applications being developed on the world wide web (WWW). Models for analyzing and designing these applications are only just beginning to emerge. In this work, we propose a 3-dimensional classification space for WWW applications, consisting of a degree of structure of pages dimension, a degree of support for interrelated events dimension and a location of processing dimension. Next, we propose usability design metrics for WWW applications along the structure of pages dimension. To measure these ,we propose CMU-WEB: a conceptual model that can be used to design WWW applications, such that its schemas provide values for the design metrics. This work represents the first effort, to the best of our knowledge, to provide a conceptual model that measures quantifiable metrics that can be used for the design of more usable web applications, and that can also be used to compare the usability of existing web applications, without empirical testing.

Uniform Solution

Accessing the Web from mobile devices is a popular practice. Trends show that the mobile space is becoming the method through which many consumers access content – both through native and web applications. These applications have expanded the browsing experience, but have also complicated the development process. A need exists for a simple, uniform solution which HTML5 is attempting to address. HTML is a mark-up language, now on its fifth edition, used for structuring and presenting content on the World Wide Web. Because of the large increase in users of mobile devices, internet access on these devices is widely used. The creation of web sites, web documents, and applications are done with HTML5, as it is compatible with both PC and mobile device browsers. However, with its lengthy development process, it is not yet apparent if HTML5 can incorporate the demands of developers in a changing environment. This paper provides an overview of the use of HTML5 in structuring and presenting content on the World Wide Web and compatibility issues on mobile browsers, key features, tool’s, and the advantages and disadvantages on the mobile web devices as well as the state of the mobile web.

Abstract Objective.—To implement an interactive program for teaching coagulation disorders on the World Wide Web. Design and Results.—The core materials in this program were derived from a personal computer software program previously designed by the authors. Three modules were developed in this program: (1) a coagulation profile to display typical results of coagulation screening tests for each disorder; (2) a differential diagnosis module to generate a list of diagnoses that fit the test results in a given case; and (3) a synopsis of coagulopathy and therapy to provide essential information on disorders and therapeutic options. A total of 41 coagulation disorders were included in the knowledge base. Conclusions.—Since the World Wide Web is increasingly more accessible to computer users, it has become an ideal medium for teaching purposes. Our experience with this program in teaching medical students and pathology residents at our institution has been very encouraging.

Conditional branching is used to direct respondents to skip inappropriate questions or to answer follow-up questions. When surveys are implemented on the World Wide Web, branching can be automated in different ways. Three implementations of conditional branching in Web-based surveys were compared: (a) a manual form which replicated the paper-and-pencil version in a scrollable window, (b) a semi-automatic form which also showed the whole survey but auto-scrolled to the next question, and (c) an automatic form that displayed only one item per screen and implemented all branching. The surveys used involved one, two, or three follow-up questions. The automatic item-by-item implementation proved significantly faster than either the manual or the auto-scrolling versions. Respondents found the auto-scrolling to be disorienting. These results suggest that automatic branching should be used but with graceful jumps that guide the respondents' focus of attention without loosing it.
