It involves a great number of techniques to choose and there is no sufficient organized information to support the selection regarding the V&V technique to be used. This paper describes an ongoing research work concerned with the definition of an approach to plan verification and validation processes. Its objective is to define how V&V activities can be supported throughout software development processes accomplished by a Software Engineering Environment (SEE). Besides V&V knowledge integrated into the SEE, this approach will also organize some practical recommendations generated by experimental studies regarding V&V techniques to support their use.

This paper presents the concepts and architectural solutions for the eSEE infrastructure and the current state of this research work at COPPE/UFRJ.

However, ontology construction is not a simple task. Thus, it is necessary to provide tools that support ontology development. This paper discusses the use of ontologies to support domain-oriented software development in ODE, an Ontology-based software Development Environment, and presents ODEd, an ontology editor developed to satisfy the requirements for an ontology editor in a DOSEE. These requirements include the definition of concepts and relations using graphic representations, automatic generation of some classes of axioms, derivation of object frameworks from ontologies, and ontology instantiation and browsing.

To study in vitro the direct influence of alveolar type II cells on mechanical stretch. Methods A549 were treated with different doses of lipopolysaccharide (LPS), 0 ng/ml, 1 ng/ml, 10 ng/ml, 100 ng/ml, 1000 ng/ml, and then A549 were lengthened 5%, 15%, 30% using a FLEXCELL tension unit 4000, a vacuum-driven device that applies strain to cells, which were cultured in six-well plates coated with collagen-I, and 12 cycles/min for 4 hours. Apoptosis was measured using the flow cytometry method that measures annexin V and propidium iodide (PI) staining. The morphological changes of apoptotic cells were observed by transmission electron microscope. Results Apoptosis could be induced in alveolar type II cells (A549) by mechanical stretch. The percentage of annexin V + PI cells increased after being treated with cyclic stretch for 4 hours by 5%, 15%, 30% in all groups. The morphological features of apoptotic cells demonstrated by transmission electron microscope were as follows: shrinkage of the cell, chromatin condensation and aggregation under the nuclear membrane as a crescent or lump, membrane-encapsulated nuclear fragment or cell organ formed by invagination of the cell membrane, and apoptotic body formation followed by vacuolization. Conclusion Apoptosis induced by mechanical stretch and LPS is dose dependent. Mechanical stretch aggravates apoptosis especially in cells treated with LPS. Annexin V and PI double staining is a specific, sensitive, and quantitative method for analyzing apoptotic cells. It is also helpful to clarify the protective mechanism of low-volume ventilation in ARDS.

However it is hard to run such studies when they require models (simulation), produce large amount of information, and explore science in large scale. In this case, a computerized infrastructure is necessary and constitutes a complex system to be built. In this paper we discuss an experimentation environment that has being built to support large scale experimentation and scientific knowledge management in Software Engineering.

Mainly in Brazil, there is an urge to enhance software processes performance aiming to improve the quality of software products and to increase Brazilian organizations competitive advantages both in the national and international markets. This work describes an approach developed to establish the base for Brazilian organizations to improve software processes. The focus of this work is to increase the software development capability of small and medium size companies in a fast pace. The presented approach consists of the development of a Reference Model for software process improvement and an appraisal method for the Brazilian software industry. This model has been deployed in several Brazilian companies thorough the support of Software Development Environments. The pilot experience and empirical validation results of application of the presented approach are also described in this paper. panies in Brazil in 2003 with ISO 9000 certificate was 214, and the number of companies with SW-CMM (Capability Maturity Model for Software) official evaluations was 30 and none with CMMI (Capability Maturity Model Integration) official evaluation.
