Multi-agent transactions for Web-based design activities

Multi-agent transactions for Web-based design activities

引用

International Conference on Computer Supported Cooperative Work in Design

作者： M. Younas Kuo-Ming Chao R. Anane A. James Data and Knowledge Engineering Research Group (DKERG) School of Mathematical and Informaiion Sciences Coventry University UK

Web-based engineering design activities require fault tolerance and concurrent access to shared resources such as databases and Web servers. Such activities are generally dynamic, cooperative, long-lived, interactive, and non-prescriptive. We propose a new multi-agent transaction model, which is based on extended transactions and multi-agent technologies. The novelty of this model is that it automatically customises transactions to the requirements of the design activities. In addition, this model is believed to improve concurrency and fault tolerance, facilitate interaction and co-operation of participating systems involved in design activities.

In the last 10 years, the Information and Communication Technologies (ICTs) revolution has redefined the structure of the 21st century healthcare organization. It is clear that the 21st century healthcare organization will bring about new healthcare services and that traditional management and technological concepts would not be the appropriate conduit for disseminating these new healthcare services. The fundamental challenge faced by the 21st century clinical practitioner is to acquire proficiency in understanding and interpreting clinical information so as to attain knowledge and wisdom. An additional challenge that must be considered is that clinical practitioners make potentially life-saving decisions whilst attempting to deal with large amounts of clinical data. We focus on the emergence of telehealth as an alternative implementation for transfer of medical information using futuristic Information and Communication Technologies (ICT). We contend that current healthcare applications are being used in a static manner; futuristic applications will need to be dynamic in nature and would call for the transfer of context-based healthcare information. A knowledge Management (KM) solution would allow healthcare institutions to give clinical data context, so as to allow knowledge derivation for more effective clinical diagnosis. It would also provide a mechanism for effective transfer of the acquired knowledge in order to aid healthcare workers as and when required Using data inputs from our collaborating organization, Applied Network Solutions (ANS), we argue that healthcare institutions that integrate KM and ICT into their main organizational processes are more likely to survive and prosper. These organizations would have a profound understanding of how to use clinical information for creating value in tangible and intangible terms.

Advances in information and communication technologies (ICT), together with the search for effective and efficient ways to deliver healthcare, have resulted in the emergence of new heath delivery systems such as Community Health Information Networks (CHIN) and Telemedicine applications. The technical infrastructure for this is often dependent upon connecting different types of computer networks, each running on different types of technologies so as to present to the user the image of a single virtual electronic health highway. It is generally agreed that current software development technology cannot deliver this due to limitations of restricted scalability, fragmented management, and inflexibility in providing business support. One of the potential solutions may be the use of Object Oriented (OO) technology. This paper explores the feasibility of combining OO technologies with healthcare-based workflow management systems (WFMS). We introduce the concept of workflow technologies and discuss the main advantages and limitations of WFMS. We detail the circumstances in which the use of WFMS could be considered and the technological factors necessary for its successful implementation. We also present an Object Management Group (OMG) model analysing it in the context of the support offered for WFMS. The main advantages and disadvantages of the model are discussed. A workflow managerrient coalition (WFMC) model is then contrasted with the OMG management model in order to identify the architectural differences between them. We focus on the relationship between workflow concepts and the position of the two reference models (WFMC and OMG) and on the use of UML in the design of information systems. We conclude by summarizing our findings on the extent to which OO technology can be used to build collaborative applications in healthcare and medical information systems.

作者： A. Dwivedi R.K. Bali A.E. James R.N.G. Naguib D. Johnston Data and Knowledge Engineering Research Group (DKERG) Coventry University UK BIOCORE School of Mathematical and Information Sciences Coventry University UK Slough Applied Network Solutions Limited UK

In this paper we look at information technology (IT) trends in the healthcare sector. We analyse recent changes in IT implementations in the healthcare sector to identify critical factors and technologies that are likely to be an integral part of healthcare institutions (HIs) in the new millennium. We contend that the recent advances in Biomedical knowledge coupled with the Genetic engineering revolution are likely to bring about an increased understanding of known diseases and will lead to the identification of new risk factors. We then highlight the fact that, despite appreciating the importance of ensuring integration between different Healthcare Information Systems, HIs are not allocating sufficient funds for this. We highlight the case of US based HIs who face IT challenges in light of a marginal percentage decrease in financial resources for IT purposes. We identify the lack of an Integrated Healthcare Information System to be the most fundamental obstacle that is denying the productivity explosion needed in the healthcare sector. To provide a realistic solution, we look at some of the technologies that together could provide solutions. We use data from our collaborating organization to present a possible low cost IT solution.

Despite substantial investments in information technology (IT), organizations have not been able to exploit the advantages of the Information and Communication Technology (ICT) revolution to the desired extent. This is also true for the healthcare sector. Twenty first century healthcare practitioners face the challenge of transforming large amounts of data into information, which then has to be converted into contextual knowledge. This process of knowledge creation and conversion is further accentuated as transformation of information into knowledge calls for: (1) contextual recognition of Information and (2) a mechanism to support effective transfer of knowledge. Also reinforced is the recognition that it is essential to have a framework that supports the dissemination of the contextual knowledge acquired. We argue the knowledge Management (KM) paradigm is aptly suited for this purpose. However, the lack of an explicit and generic framework for adopting KM has hindered its rapid acceptance in the healthcare sector. Using data inputs from a collaborating organization, we then present the Organization Current knowledge Design (OCKD) model - a holistic and generic KM framework that could help healthcare organizations to navigate this difficult change process.

With rapid development of wireless communications as well as positioning technologies, the concept of moving objects has become more and more important, which are challenging the traditional database technologies. Since moving objects change their dynamic attributes continuously, it is impractical to issue explicit updates for every change. In this paper, we introduce an indexing structure based on quadtree, which can be applied to one-dimensional, two-dimensional, three-dimensional and any other multi-dimensional abstract data space. We also present the querying process based on the indexing structure.

In recent years, healthcare institutions have had problems accessing and maintaining the large amounts of data they deal with. This paper identifies current approaches and technologies which relate to patient administration systems. It argues that, in the near future, WWW-based multimedia patient administration systems would become the norm for healthcare institutions. The development and acceptance of web-based multimedia patient administration systems is likely to aggravate the problem of healthcare institutions being flooded with large amounts of clinical data. A large amount of clinical procedures relating to patient management are repetitive and Workflow Management Systems (WFMS) can automate these repeated activities. We believe that the introduction of WFMS would enable healthcare institutions to face this challenge of transforming large amounts of medical data into contextually relevant clinical information. The central contention of this paper is that there is a dynamic connection between healthcare, workflow and internet technologies, which is being ignored. This paper further establishes that it is possible to build a virtual electronic health record database based on the client server architecture using current internet and object-oriented (OO) technologies.

A mobile agent framework for telecardiology

A mobile agent framework for telecardiology

Annual International Conference of the IEEE engineering in Medicine and Biology Society (EMBC)

作者： K.-M. Chao R. Anane J. Plumley N. Godwin R.N.G. Naguib Data and Knowledge Engineering Research Group (DKERG) Coventry University UK BIOCORE Coventry University UK

It is generally recognised that telecommunications and the internet in particular are changing the way healthcare is delivered in cardiology. Current. implementations of telecardiology are often characterised by a centralised approach. Within this set-up a central system is connected to various remote sites. The central system has to keep track of the activities and of the state of these sites through constant communication with them. This scheme requires large volumes of data, particularly in the case of electrocardiograms (ECGs), to be generated in the remote sites and then to be transmitted to a central control system. This often leads to bottlenecks in communication that may adversely affect the quality of care. In this paper we propose a decentralised approach based on a combination of mobile agents (MA) and an Object Request Broker (ORB) mechanism. Its main aim is to support interoperability and to optimise the monitoring processes by reducing unnecessary communication. MAs possess a degree of autonomy that enables them to filter data on the remote site, and thus ease the load on the central monitoring system. they have the added advantage that they can be customised to meet individual needs. The ORB mechanism is incorporated in order to increase the reliability of MAs and to facilitate the integration of various ECG analysis software systems available on the market. It is expected that the proposed system will provide a framework for improved monitoring of patients and will lead therefore to better healthcare in cardiology.

International Conference on database Systems for Advanced Applications

ISBN: (纸本)0769509967

Replication is one of the key technologies in promoting the performance of mobile database systems. In this paper, a novel mobile database replication scheme, the transaction-level result-set propagation (TLRSP) model, is put forward. A conflict detection and resolution strategy based on TLRSP is discussed in detail and its implementation algorithm is proposed. In the TLRSP model, mobile users are allowed to access local replicas of the database and to submit local transactions when the system is disconnected. The locally committed transactions are sent to a fixed database server for conflict reconciliation and result-set incorporation when the system is reconnected. The TLRSP model uses the incremental refreshing method to synchronize database replicas and to maintain the consistency of the replicated mobile database system.
