In software and systems engineering, the phrase use case is a polyseme with two senses: . A usage scenario for a piece of software; often used in the plural to suggest situations where a piece of software may be useful.
A use case diagram [1] is a graphical depiction of a user's possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well. The use cases are represented by either circles or ellipses. The actors are often shown as stick ...
Convenience: SPs are able to provide cases that are needed at the time they are needed. They are likely to be more reliable, and may tolerate more students than real patients. Standardization: The use of standardized clinical scenarios allows direct comparison of the students' clinical skills, locally as well as nationally and internationally.
Use case analysis is a technique used to identify the requirements of a system (normally associated with software/process design) and the information used to both define processes used and classes (which are a collection of actors and processes) which will be used both in the use case diagram and the overall use case in the development or redesign of a software system or program.
Sequence diagrams are sometimes called event diagrams or event scenarios. For a particular scenario of a use case, the diagrams show the events that external actors generate, their order, and possible inter-system events. [2] The diagram emphasizes events that cross the system boundary from actors to systems.
Case series have a descriptive study design; unlike studies that employ an analytic design (e.g. cohort studies, case-control studies or randomized controlled trials), case series do not, in themselves, involve hypothesis testing to look for evidence of cause and effect (though case-only analyses are sometimes performed in genetic epidemiology ...
In genetics, the index case is the case of the original patient (i.e. propositus or proband) that stimulates investigation of other members of the family to discover a possible genetic factor. [ 14 ] The term can also be used in non-medical fields to describe the first individual affected by something negative that since propagated to others ...
The American Board of Emergency Medicine employs the use of medical simulation technology in order to accurately judge students by using "patient scenarios" during oral board examinations. [2] However, these forms of simulation are a far cry from high-fidelity models that have surfaced since the 1990s. [7]
