In healthcare chain workflow management, urgent requests and critical messages in these systems (... more In healthcare chain workflow management, urgent requests and critical messages in these systems (referred to as alerts) have to be delivered and handled timely. Presently, most systems cannot address urgency and alerts are often handled in an ad-hoc manner. In this paper, we propose a sophisticated alert management system (AMS) for effective healthcare chain workflow management under urgent constraints. We develop a model for specifying alerts, in which alerts are associated with healthcare tasks and a set of parameters are captured for their routing and urgency requirements. Further, alerts also serve as a mechanism for both process and data integration. The AMS matches the specialties of healthcare personnel and functionalities of Web Services providers to receive an alert, based on the alert specification. We then propose a routing mechanism that is initiated when the alert message is not acknowledged or serviced within the deadline, so that the alert can be re-routed if necessary. Monitoring is especially essential to ensure timeliness and availability of services, otherwise suitable exceptions should be raised and handled. We outline our implementation framework with Web Services for communications among healthcare service providers and mobile devices for medical professionals. We demonstrate the applicability of our approach with a pilot prototype medical house-call system (MHCS) with evaluations of medical professionals.

Further with the invention of new interaction devices, the context in which the service is being used becomes an integral part of the activity carried out with the system. This demands a new paradigm for system requirements elicitation and design in order to make good use of such extended context information. Instead of redesigning or adapting existing e-government services in an ad-hoc manner, we introduce a methodology for the elicitation of contextaware adaptation requirements and the matching of context-awareness features to the target context by capability matching. For the implementation of these adaptations, we propose the use of three tiers of views: user interface views, data views, and process views. This approach centers on a novel notion of process views to ubiquitous government (u-government) service adaptation, where mobile users may execute a more concise version or modified procedures of the original process according to their context. The process view also serves as the key mechanism for integrating user interface views and data views. We demonstrate our methodology by extending an egovernment appointment service into a mobile one with context support.

Agents equipped with a set of rules instructed by humans, surf the web, discover other agents and/or humans, and take decisions forming agreements in an autonomous way. Despite recent legislations on electronic contracting, there are no legislations governing automatic agent transactions except one preliminary attempt in the USA. In this paper, we are looking into the new legal issues that arise due to intelligent agents in automatic contracting. There are few scattered opinions in the literature and are inadequate to address these issues. So, we present a legal framework to analyze these novel issues and show why even recent legislations cannot adequately address this problem. We identify many of these issues which are rooted at the authorization management in agent delegation. Therefore, we advocate solutions that consider both legal and technical aspects. Based on current legal and business practices, we develop a conceptual model for agent authorization. We propose the use of a Contract Agent Authorization Platform (CAAP) that also supports alerts and acknowledgments, and illustrate the platform with typical use cases. We attempt to investigate the ambiguities of the existing legal framework on contracting agents that emerged due to new technical developments in the field.

Urgent requests and critical messages in these systems (referred to as alerts) should be delivered and handled timely. In particular, humans are often involved in critical conditions. Presently, most E-service systems cannot address these requirements, and alerts are often handled in an ad-hoc manner. In this paper, we propose a sophisticated alert management system for effective e-service integration under urgent constraints. We develop a model for specifying alerts, in which alerts are associated with service requests and a set of parameters are captured for their routing. The alert monitor matches the service provider to receive an alert, based on the alert specification. We then propose a routing mechanism that is initiated when the alert message is not acknowledged or serviced within the deadline, so that the alert can be forwarded to other suitable services if necessary. Monitoring is especially essential to ensure timeliness and availability of services, otherwise suitable exceptions should be raised and handled. We outline our implementation framework of an Alert Management System (AMS) with includes Web Services for B2B interactions, together with multiple-platform support for human users. We demonstrate our approach with an example medical house-call AMS.

Workflow inter-operability is therefore an important issue for workflow enactment in such an environment. In this paper, we introduce a novel concept of workflow views as a fundamental support for E-service workflow inter-operability and for controlled visibility by external parties. Furthermore, we develop a contract model based on workflow views and demonstrate how management of contracts can be facilitated, with an Internet start-up E-service inter-organization workflow example.

At the same time, healthcare environments are by nature "mobile" where doctors and nurses do not have fixed workspaces. Irregular and exceptional events are generated in daily hospital routines, such as operations rescheduling, laboratory/examination results, and adverse drug events. These events may create requests that should be delivered to the appropriate person at the appropriate time. Those requests that are classified as urgent are referred to as alerts. Efficient routing and monitoring of alerts are keys to quality and cost-effective healthcare services. Presently, these are generally handled in an ad hoc manner. In this paper, we propose the use of a healthcare alert management system to handle these alert messages systematically. We develop a model for specifying alerts that are associated with medical tasks and a set of parameters for their routing. We design an alert monitor that matches medical staff and their mobile devices to receive alerts, based on the requirements of these alerts. We also propose a mechanism to handle and reroute, if necessary, an alert message when it has not been acknowledged within a specific deadline. . Her research interests focus on information systems for hospital applications and software systems for diagnostic methods on carotid atherosclerosis.

Therefore, workflow inter-operability in such an environment is an important issue for enacting workflows. In this article, we introduce our approach of using workflow views as a fundamental support for Eservice workflow inter-operability and for controlled visibility of (sub-)workflows by external parties. We discuss various aspects of a workflow view, and their semantics with example usage. Furthermore, we develop a contract model based on workflow views and demonstrate how management of e-contracts can be facilitated, with an Internet start-up E-service inter-organization workflow example.

Such e-services typically require collaborative enactment of workflows across multiple organizations. In this paper, we propose the use of workflow views as a fundamental support mechanism for the interoperability of multiple workflows across business organizations. We present a meta-model of workflow views and their semantics using a cross-organization workflow example based on a supply-chain e-service. We also formulate an interoperation model of workflow views and its consistency criteria. Finally, this paper presents an implementation of the model based on XML and contemporary Web services technologies, with adaptation to our E-ADOME workflow engine.
