Tool-Support – A Use Case Management Repository

Scenarios has become a popular technique for requirements elicitation and specification building. Since scenarios capture only partial descriptions of the system behavior, an approach for scenario composition and/or integration is needed to produce more complete specifications. The Unified Modeling Language (UML), which has become a standard notation for object-oriented modeling, provides a suitable framework for scenario acquisition using Use Case diagrams and Sequence or Collaboration diagrams. In this paper, we suggest an algorithmic and tool support for composing and integrating scenarios that are represented in form of sequence diagrams. We suggest four operators (;: sequential operator, ||: concurrent operator, ?: conditional operator andÂ * :iteration operator) to compose a set of scenarios that describe a use case of a given system. In this paper, we suggest also to apply the scenario approach to B2B systems (Business to Business). We propose to develop B2B systems as a three activities process deriving formal specifications and code skeletons from UML scenarios. Activities of this proposed process are generally automatic and are supported by a set of developed algorithms and tools.

Abuse Treatment

Case management has been used to link clients and the service system, but is loosely defined and poorly understood. The aims of this study were to describe the use and purposes of case management within substance abuse treatment programs, and also the structures and processes for providing case management services. A descriptive survey was done, with 50 program directors of 134 treatment programs (with 205 case managers), in Los Angeles County. Results showed that 80% of directors reported they use case management. Half of the programs use case management both before and after discharge, and 72% provide case management to all clients. Case managers’ most important roles are to develop treatment plans and prevent relapse during treatment, and 60% of directors indicate the case managers in their programs are also counselors. Case managers perform numerous roles of coordination and advocacy. Eighty percent of case managers follow the care of the client during treatment and 32% of directors reported a case load of 1-10, while 26% reported a case load of 11-20. The professional background of case managers varies from chemical dependence professional to social worker or nurse. Twenty percent of program directors plan to increase case management in the future.
