    Accessing Patient Records in Virtual Healthcare Organisations

    No full text
    The ARTEMIS project is developing a semantic web service based P2P interoperability infrastructure for healthcare information systems that will allow healthcare providers to securely share patient records within virtual healthcare organisations. Authorisation decisions to access patient records across organisation boundaries can be very dynamic and must occur within a strict legislative framework. In ARTEMIS we are developing a dynamic authorisation mechanism called PBAC that provides a means of contextual and process oriented access control to enforce healthcare business processes. PBAC demonstrates how healthcare providers can dynamically share patient records for care pathways across organisation boundaries

    Get PDF
    The complexity of music recommendation systems has increased rapidly in recent years, drawing upon different sources of information: content analysis, web-mining, social tagging, etc. Unfortunately, the tools to scientifically evaluate such integrated systems are not readily available; nor are the base algorithms available. This article describes Graph-RAT (Graph-based Relational Analysis Toolkit), an open source toolkit that provides a framework for developing and evaluating novel hybrid systems. While this toolkit is designed for music recommendation, it has applications outside its discipline as well. An experiment—indicative of the sort of procedure that can be configured using the toolkit—is provided to illustrate its usefulness

    Advances in network and imaging technology, coupled with the availability of 3-D datasets such as the Visible Human, provide a unique opportunity for developing information systems in anatomy that can deliver relevant knowledge directly to the clinician, researcher or educator. A software framework is described for developing such a system within a distributed architecture that includes spatial and symbolic anatomy information resources, Web and custom servers, and authoring and end-user client programs. The authoring tools have been used to create 3-D atlases of the brain, knee and thorax that are used both locally and throughout the world. For the one and a half year period from June 1995–January 1997, the on-line atlases were accessed by over 33,000 sites from 94 countries, with an average of over 4000 ‘‘hits’’ per day, and 25,000 hits per day during peak exam periods. The atlases have been linked to by over 500 sites, and have received at least six unsolicited awards by outside rating institutions. The flexibility of the software framework has allowed the information system to evolve with advances in technology and representation methods. Possible new features include knowledge-based image retrieval and tutoring, dynamic generation of 3-D scenes, and eventually, real-time virtual reality navigation through the body. Such features, when coupled with other on-line biomedical information resources, should lead to interesting new ways for managing and accessing structural information in medicine

    Get PDF
    The rapid growth of mobile technology has expedited ubiquitous information access via handheld devices. However, the fundamental natures of mobile information systems are different from those of desktop applications in terms of purpose of use, device features, communication networks, and working environments. This poses various challenges to mobile information systems on how to deliver and present multimedia content in an effective and adaptive manner. One of the major challenges is to deliver personalized information to the right person in a preferred format based on the changing environment. This paper proposes an innovative framework for developing mobile applications that deliver personalized, context-aware, and adaptive content to mobile users. The framework consists of four major components: information selection, content analysis, media transcoding, and customized presentation. It can be applied to a variety of mobile applications such as mobile web, news alert services, and mobile commerce

    Intrusion Detection System (IDS) is one of the security measures being used as an additional defence mechanism to prevent the security breaches on web. It has been well known methodology for detecting network-based attacks but still immature in the domain of securing web application. The objective of the paper is to thoroughly understand the design methodology of the detection system in respect to web applications. In this paper, we discuss several specific aspects of a web application in detail that makes challenging for a developer to build an efficient web IDS. The paper also provides a comprehensive overview of the existing detection systems exclusively designed to observe web traffic. Furthermore, we identify various dimensions for comparing the IDS from different perspectives based on their design and functionalities. We also provide a conceptual framework of an IDS with prevention mechanism to offer a systematic guidance for the implementation of the system specific to the web applications. We compare its features with five existing detection systems, namely AppSensor, PHPIDS, ModSecurity, Shadow Daemon and AQTRONIX WebKnight. The paper will highly facilitate the interest groups with the cutting edge information to understand the stronger and weaker sections of the web IDS and provide a firm foundation for developing an intelligent and efficient system

    Placing the Networks on the Web: Challenges and Opportunities for Managing in Developing Asia

    Get PDF
    Placing the networks on the Web poses a fundamental challenge, but also provides new opportunities for managing in Developing Asia. There is a huge efficiency gap between the region's manufacturing systems and the management of complementary, knowledge-intensive support services. The challenge is to reduce this gap as quickly as possible by embracing the Internet as a core business function, despite a weak base of accumulated knowledge of how to manage IT-based information systems. Asian companies, even the best, lag substantially behind their American and European counterparts. There is a potential vicious circle that needs to be broken: a belated transition to IT-based information systems has prevented the accumulation of knowledge, through trial-and-error, of how to design and implement an appropriate IT organization that reflects the peculiar strengths and weaknesses of diverse Asian management systems. Limited resources prevent any attempt to address these problems in a big leap forward. This implies that in-house efforts need to be supplemented with outsourcing of IT services. There is also a need for strategic partnering with major suppliers of Internet software and networking equipment. The opportunity is that the Internet provides almost unlimited opportunities for the outsourcing of mission-critical support services, such as ERP (enterprise resource planning), HRM (human resource management). Furthermore, fierce competition among major producers of Internet software and networking equipment has created a buyers' market - placing Asian firms in a reasonably strong bargaining position. These developments are generally not well covered by existing studies, which are primarily focused on developments in the U.S. and Europe. The paper tries to fill this gap, and explores how placing global production networks on the Web affects managing in Developing Asia. A conceptual framework is introduced in parts 1 to 3. That framework is then applied to one of the role models of managing in Asia, Taiwan's Acer Group. Part 1 introduces a taxonomy of expected benefits from Internet-enabled transformations of business organization. In part 2, we argue that the real issue is to analyze how the Internet reshapes the organization of global production networks. In part3, we access conflicting claims on how an increased use of the Internet to manage global production networks affects international knowledge diffusion. In part 4, the example of Taiwan's Acer Group is used to describe the challenge for Asian firms to embrace the Internet as a key management function. And in part 5, we ask what Acer's experience tells us about Developing Asia's opportunities.

    Developing Legacy System Migration Methods and Tools for Technology Transfer

    This paper presents the research results of an ongoing technology transfer project carried out in coopera- tion between the University of Salerno and a small software company. The project is aimed at developing and transferring migration technology to the industrial partner. The partner should be enabled to migrate monolithic multi-user COBOL legacy systems to a multi-tier Web-based architecture. The assessment of the legacy systems of the partner company revealed that these systems had a very low level of decompos- ability with spaghetti-like code and embedded control flow and database accesses within the user interface descriptions. For this reason, it was decided to adopt an incremental migration strategy based on the reengineering of the user interface using Web technology, on the transformation of interactive legacy programs into batch programs, and the wrapping of the legacy programs. A middleware framework links the new Web-based user interface with the Wrapped Legacy System. An Eclipse plug-in, named MELIS (migration environment for legacy information systems), was also developed to support the migration process. Both the migration strategy and the tool have been applied to two essential subsystems of the most business critical legacy system of the partner company

    Web assisted teaching: an undergraduate experience

    Get PDF
    The emergence of the Internet has created a number of claims as to the future of education and the possibility of dramatically changing the way in which education is delivered. Much of the attention has focussed on the adoption of teaching methods that are solely web-based. We set out to incorporate web-based teaching as support for more traditional teaching methods to improve the learning outcomes for students. This first step into web-based teaching was developed to harness the benefits of web-based teaching tools without supplanting traditional teaching methods. The aim of this paper is to report our experience with web-assisted teaching in two undergraduate courses, Accounting Information Systems and Management Accounting Services, during 2000. The paper evaluates the approach taken and proposes a tentative framework for developing future web-assisted teaching applications. We believe that web-assisted and web-based teaching are inevitable outcomes of the telecommunications and computer revolution and that academics cannot afford to become isolated from the on-line world. A considered approach is needed to ensure the integration of web-based features into the overall structure of a course. The components of the course material and the learning experiences students are exposed to need to be structured and delivered in a way that ensures they support student learning rather than replacing one form of learning with another. Therefore a careful consideration of the structure, content, level of detail and time of delivery needs to be integrated to create a course structure that provides a range of student learning experiences that are complimentary rather than competing. The feedback was positive from both extramural (distance) and internal students, demonstrating to us that web sites can be used as an effective teaching tool in support of more traditional teaching methods as well as a tool for distance education. The ability to harness the positives of the web in conjunction with more traditional teaching modes is one that should not be overlooked in the move to adopt web based instruction methods. Web-based teaching need not be seen as an all or nothing divide but can be used as a useful way of improving the range and type of learning experiences open to students. The Web challenges traditional methods and thinking but it also provides tools to develop innovative solutions to both distance and on campus learning. Further research is needed to determine how we can best meet the needs of our students while maintaining high quality learning outcomes

    Every aspect of management relies on information to succeed. According to Adekeye (1997) information has become a critical resource to the organizations and individuals and should be properly managed to ensure its cost effective use. Best (1988) stated that to improve the performance of the organization, information management must be economic, efficient and effective. Information systems and organization have been highly interconnected with each other. Adekeye (1997) and Rob and Corone (2000) stated that the development and used of information is generated, accessed and distributed. The Web can be considered to be a very large semi-structured database that holds vast amounts of useful information is generated, accessed and distributed. The Web can be considered to be a very large semi-structured database that holds vast amounts of usefull information. These days, good decision requires information that comes from a manageable data storage. The internet has transformed database management system and put them in move towards Web enabled database application. Many organizations are now taking full advantage of the web in becoming web centric organization. In fact, many database professionals believe that web database as a significant element in information system development. Hence, this study discusses the database system development and framework in developing a school information management system prototype, using Apache, MySQL and PHP. The system development was designed using the Database Development Life Cycle (DBLC) approach. The web based School Information Management System prototype can be used as a reference in the implementation of web- based management system for the schools
