i.e. the Mobile eHealth (MeH), developed in the context of the
 
IST PLASTIC project aimed at supporting self-adapting and
 
context-aware services. The goal of the case study is to show
 
how to model a service-based application and to demonstrate
 
that model-based solutions are suitable to generate Quality of
 
Service (QoS) models and adaptable code from service models.

=== Business Goals ===

The '''MeHQnmodel.jsimg''' is a queuing Network model that has been created using the Java Modeling Tool [http://jmt.sourceforge.net/]. The QN model has beed derived from the MeH UML Model following the PRIMAUML model-based performance methodology [http://dl.acm.org/citation.cfm?id=607042]. The '''MeHQnmodel.jsimg''' can be opened in JMT and it can be executed to derive the performance indeces of interest.

It's worth noting that the transformation from UML2JMT has not been implemented. However a similar UML2PMIF transformation has been implemented in MOSQUITO starting from PLASTIC UML Model (see [http://sealabtools.di.univaq.it/tools.php]).

It's worth noting that the case study proposes a possible implementation of the MeH MIDlets while a running example of the MeH System was implemented by Telefonica [http://www.ist-plastic.org/] and it is not available here. However an excerpt of the adaptable JAVA code for the MeH case study is shown in the paper published at PESOS 2012 [http://www.s-cube-network.eu/pesos-2012].

| By invoking the PDR service, the doctors retrieve mixed media information of their patients that combines text with or without different kinds of images referring to their personal data, their medical histories and patient-related diseases. The results can be displayed on the doctors’ handheld device. A more detailed description of this service is provided in [http://www.sti.uniurb.it/paco/Products/fase_2010b.pdf].

! Description
 
| The MeH system shall be a context-aware and adaptable service. Context is a set of heterogeneous information that can be sensed by and influence the system behavior. At design time, it results in artifacts (i.e., models) where structural and behavioral descriptions of the MeH System can be combined with a context model. At run time, it corresponds to the availability of an appropriate middleware that is capable to monitor the execution context and to adapt the system behavior accordingly.

=== Strategic Dependency Model and Context Diagram ===
 
 
 
The SDD figure illustrates the strategic dependency diagram of the case study. The diagram puts in evidence
 
the business goals shared among the related actors. For example, in the diagram we can note that the
 
Doctor makes a remote diagnosis for the Patient. He/She can also retrieve multimedia data (text and images) about the assisted patients by accessing databases from the MeH System.

The following figure illustrates the context diagram of the current case study. In the context diagram, all the actors that appear in the business goals and scenarios are agents.

=== Domain Model===
 
 
 
The figure below illustrates the domain model of the current case study. The model is represented using a UML notation. In particular the model shows the entities of the scenario, the actors and the relationship among them.

|- style="background:white; color:black"
 
! Detailed Operational Description
 
| During the medical examination, the doctor or other medical staff may need access to the patient’s previously recorded and now archived health data (that is, blood test results, X-ray images, etc.) which were either recorded in the same location or at a different place. For instance, this data might have been recorded at a different hospital (which possibly belongs to a different hospital chain).

! Problems and Challenges
 
| The problems and challenges related to this scenario are the following:
 
 
 
* Legal and technical issues with distributed and shared patient records
 
* Integration across domains
 
* Horizontal (enterprise information systems) and vertical integration (devices)
 
* Platform heterogeneity, interoperability
 
* HIPAA privacy and security compliance
 
* Patient chart autorization access and protection
 
* Procedure that maintain electronic protected health information to allow access only to those persons or programs that have been
 
granted access rights
 
* Emergency access procedure for obtaining necessary electronic protected health information during an emergency
 
* Dependability, performance, security, and trust

|- style="background:white; color:black"
 
! Detailed Operational Description
 
| The doctor also needs access to the data recorded online during the consultation by either the doctor himself or his assistants. He may, in addition, need data that was recorded shortly before the consultation, or that was collected in the hospital or at home during a long-term monitoring with a mobile diagnostic device like, for instance, an ambulatory blood pressure unit. It is even conceivable that the doctor would use diagnostic data received from nanobots (that is, agent-like devices of nanometre-size brought into a human body for diagnosis or even for therapy). In addition, whatever kind of data he is using, the doctor should be supported in his analysis by expert systems and databases.

! Detailed Operational Description
 
| To reach a diagnosis during a complex examination, the doctor may need to use several devices in several locations. The devices could be a general-purpose handheld computer or a specific integrated device for medical diagnostics, for instance, an X-ray device. They are often located in the same hospital, but also their usage in a different place, e.g. the patient’s home, is conceivable. For the execution of patient checks a doctor could exploit different devices. In this case, their status has to be properly aligned.

This page describes the artifacts of the Mobile eHealth case study.

Description

Process.png

Figure 1 shows the PLASTIC Development Process and the related artifacts.

The MeH UML Model has been created using the MagicDraw UML modeling tool that can be downloaded here [www.magicdraw.com/]. MagicDraw UML can be seamlessly integrated with the Eclipse Modeling Project [1]. For this reason, the MeH UML Model can be opened both in MagicDraw and in any Eclipse UML compliant plugin of the Eclipse platform.

The MeHQnmodel.jsimg is a queuing Network model that has been created using the Java Modeling Tool [2]. The QN model has beed derived from the MeH UML Model following the PRIMAUML model-based performance methodology [3]. The MeHQnmodel.jsimg can be opened in JMT and it can be executed to derive the performance indeces of interest. It's worth noting that the transformation from UML2JMT has not been implemented. However a similar UML2PMIF transformation has been implemented in MOSQUITO starting from PLASTIC UML Model (see [4]).

UML2wsdl_1.0.0. jar is an archive containing a model transformation from a PLASTIC Service UML Model to WSDL. It has been implemented in ATL. For additional information see the User Guide that can be downloaded from the Download Section.

The RD Adaptable Midlet is a code artifact that uses an extended Java grammar as proposed by the CHAMELEON Framework. It's worth noting that the case study proposes a possible implementation of the MeH MIDlets while a running example of the MeH System was implemented by Telefonica [5] and it is not available here. However an excerpt of the adaptable JAVA code for the MeH case study is shown in the paper published at PESOS 2012 [6].
