Background: Pulmonary nodular excavation should firstly evoke tuberculosis or necrosis broncho-pulmonary tumor, particularly: epidermoid carcinoma. The case discussed here illustrated these difficulties in patients with rheumatoid arthritis (RA). Case Presentation: A 63-year-old woman was presented with a-three-year history of RA and a recent discovery of an excavated pulmonary nodule. Initi...

We present a formal framework for the implementation of a concep tual data model in terms of an internal data model within a two level architecture taking into account schema consistency and instance com patibility Within that framework the consequences of schema changes are investigated leading to a homogeneous formalization of existing ap proaches to schema evolution On that basis we introduc...

In this study we present an approach to address the issues of synchronization, evolution control and version granularity in Software Configuration Management (SCM). Our approach is based on a unified model developed during software lifecycle. The unified model consists of a set of different kinds of model and the interlinks information between these models, such models includes Analysis and des...

Variability management in business processes domain is considered as a key of reuse. Research in this field focused mainly on variability modeling and resolution; neglecting the evolution aspect. The study of existing tools in this domain shows the lack of solutions integrating both the evolution management, and the change propagation with respect to the variability. The need for evolution emer...

In the present business atmosphere, an organization should be able to respond to environmental needs occasioned by rapid and dynamic evolution as quickly as possible. It is obvious that such ability is impossible without a proper strategic approach, strategic thinking, and a suitable management accounting system. This study attempts to investigate the relationships between strategy, management ...

There exists a current trend in database technology to make databases more extensible and exible, or even to generate databases for speci c customer needs. So far, schema management and especially schema evolution have been excluded from this trend. In this paper, we propose a new approach to schema management and topics centered around it, like schema consistency and schema evolution. This app...

EU-IST Integrated Project (IP) IST-2003-506826 SEKT Deliverable D3.1.1 (WP1.1) We present a survey of related work on ontology management and evolution. We then describe methods for evolution of OWL ontologies and their partial implementation in the prototypes dlpconvert and evOWLution. The appendix contains a detailed user guide for various tools of the KAON tool suite which forms a basic onto...
