In addition, this will minimize the mistakes in diagnosis and treatment processes. To this end, it is possible to use Clinical Decision Support Systems that implement the clinical guidelines. Clinical guidelines published by international associations are not suitable for developing countries such as Sri Lanka, due to the economic background, lack of resources, and unavailability of some laboratory tests. Hence, a set of clinical guidelines has been formulated based on the various published international professional organizations from a Sri Lankan context. Furthermore, these guidelines are usually presented in non-computer-interpretable narrative text or non-executable flow chart formats. In order to fill this gap, this research study finds a suitable approach to represent/organize the clinical guidelines in ...

Various strategies have been applied to improve adherence, however many of these strategies lack the interaction and personalisation-aspect which has been shown to be crucial to the patients. This paper discusses the importance of personalised interaction in improving patients' medication adherence, and the characteristics needed in an avatar to simulate such human-human interactions.

Contentbased indexing of multimedia has always been a challenging task. The enormity and diversity of the multimedia content on the World Wide Web (WWW) adds another dimension to this challenge. Today multimedia elements are increasingly being embedded in Web documents, and are being actively used to enhance the description of the document content. Since such documents over the WWW provide a rich source of information, the use of multimedia elements in Web documents has become very prevalent. In this paper, we first give a thorough review on the existing literature related to the traditional content-based image retrieval (CBIR) systems along with the methodology of relevance feedback. We then propose a unified approach for image indexing and retrieval for our Image Search retrieval system that performs relevance feedback on both the images' semantic contents represented by parts of the Web document as well as the low-level visual features. In addition, we will establish an approach with which semantic content and low-level features can be seamlessly integrated for the relevance feedbacks. More specifically, we will examine closely a number of ways that would combine visual and textual information for the content based indexing of multimedia on the Web. In particular, we will also propose and scrutinize different strategies of incorporating various mono media indexing approaches to create a multimedia indexing scheme for the purpose of image searches.

It has been reviewed internally and by external committees thrice in the last twelve years. These years have witnessed tremendous growth of the Web and Web-based applications. The tools and technologies supporting the Web and Web-applications have mushroomed and methodologies have been introduced in the Web Engineering area. Consequently, the concerns and issues that initially motivated the development of the Web Engineering curriculum have also evolved over time. This paper describes our experience of delivering Web Engineering curriculum, the problems encountered, the solutions to those problems and the lessons learnt.

Multimedia involves the use of multiple forms of communication media in an interactive and integrated manner. At present, textual data is the media commonly used to provide the interactivity (due to the ease with which discrete elements are identi ed). It is common practice to follow links from words or phrases within text to associated information elsewhere in the database. To achieve a similar degree of functionality with image data typically requires that each image be processed by hand, indicating the objects and locations within the image. This paper describes a simple object recognition system which allows the speci cation of 3-dimensional models which can then be used to recognise objects within any image, in an analogous fashion to words within text. This enables image data to be become a truly active media, within a multimedia database. It provides a signi cantly enhanced level of functionality with minimal additional e ort required during data entry. The basic algorithm is described and then an example application is outlined, along with feedback from users of the system.

The toolmakers agreed to eTransforming their individual businesses, and to collaborate with each other as a virtual organization. Results to date show progress in eTransforming their organizations and steady movement towards eCollaboration. It is suggested that trust is a crucial underlying aspect of successful collaboration, and as such needed to be addressed earlier in this project. The next step in this research will be to deploy the identified strategies and evaluate the outcomes. Future studies include the expansion of the framework and strategies to other Australian toolmakers.

As TCM practice differs significantly from western medicine both in diagnosis and treatment, using information systems created for western medicine is not suitable. There is a need for information systems developed specifically for TCM practitioners to manage patient consultation and treatments. Such system should be designed to facilitate safe and effective practice by providing decision support, utilising existing knowledge such as known herb-drug interactions to signal safety risks. Utilising current and developing standards and vocabularies such as those developed by the World Health Organisation (WHO) is important to facilitate interoperability with other systems. To facilitate continued growth in consumer demand, this type of system should be compatible with the needs of the individual electronic health records and other medical systems, and provide interfaces to external systems such as Medicare, pathology and radiology systems, and insurance systems. This paper presents the high level design of a patient consultation system for TCM practitioners that addresses the individual practitioner's needs for health records entry, storage, retrieval, display and support in managing health care delivery to patients and be part of Australia's emerging e-health system.

This approach extends Activity Based Costing (ABC) and Critical Path Method (CPM) principles for the purpose of capturing, measuring, modelling and reporting Greenhouse Gas (GHG) emissions. The Green ABM not only looks at GHG emissions but also considers cost and time as well. Thus, this provides a holistic picture of these inter-dependent dimensions to the organizational manager for decision making. Furthermore, this research shows that Green ABM can be used to minimise the costs associated with the timing of activities while keeping other business objectives in consideration.

When business processes are automated using Web-based workflow systems (WWS), process evolutions and changes need to be reflected in these implemented systems. Evolutions in business processes essentially mean altering process elements - actions, participants, object, and rules. In a process, elements are interlinked and woven together to achieve business objectives of an organization. Thus, a change in one element creates propagating impact on the other elements that are linked to it. Therefore, it is critical to understand constraints, associations and dependencies (CAD) among process elements for effective management of process evolution in WWS. Previous studies on CAD among process elements mostly focus on (at most) one or two process elements at a time. This paper brings together these isolated works into a single CAD model of process elements. Cohesive and complete nature of this model, lays the foundation to effective management of process evolution in WWS.

Often it is a process without a well-defined ending point. In order to allocate resources and develop a Web site, we need to divide the overall process into a set of sub processes that are well defined and have measurable outcomes. To identify the required sub processes first we need to understand the broader issues and specific requirements of the stakeholders. This is known as the context analysis. Next we can bring in technologies and develop an overall architecture or a product model to solve technology related issues. Once we have a product model we can identify sub processes required to implement this product model. Also we need to have a set of sub processes to address non technical issues identified during the context analysis phase. These sub processes can be converted into a project plan by allocating resources and putting a time schedule. Based on the project plan, development activities can take place and when completed it moves into a maintenance phase. This paper describes how we used this systematic approach to develop a large maintainable Web site.

The system makes extensive use of techniques of logic programming [1] to enable effective software change management, requirements traceability and continuous creation of templates for cross project use. A repository of such templates is essential to the attainment of level 5 in the CMM model . This is because with such a repository in place, a manager can switch a project from a waterfall process model to a prototyping model when there is such a need. Furthermore, these templates are useful towards procedure reuse in the sense that they can be interconnected and then instantiated to give rise to new and more complex process .
