1. USING RESEARCH METHODS IN HUMAN COMPUTER INTERACTION TO DESIGN TECHNOLOGY FOR RESILIENCE
ABSTRACT Research in human computer interaction (HCI) covers both technological and human behavioural concerns. As a consequence, the contributions made in HCI research tend to be aware to either engineering or the social sciences. In HCI the purpose of practical research contributions is to reveal unknown insights about human behaviour and its relationship

2. Fish passage system in an irrigation dam (Pilcomayo River basin ): when engineering designs do not match ecohydraulic criteria
The Route 28 Dam has the potential to block fish movements from La Estrella marsh to the Pilcomayo River. In addition, the many fish that concentrate immediately downstream of the dam may suffer high mortality when they are stranded during low water periods. The goals of this study are to determine if fish are able to pass the spillway and to assess if the d

8. Uma Proposta de MÃtricas para Avaliar Modelos i*
The Goal-Oriented Requirement Engineering has shown a promising way to describe software systems. It provides a natural mechanism to structure complex requirement documents through goals providing a mechanism to justify the existence of the requirements and facilitate the management of conflicting requirements. In this context, different approaches that use

10. Avaliação da aplicabilidade do Model Driven Architecture à manutenção de versões personalizadas de sistemas ERP / Assessment of the applicability of Model Driven Architeture to the maintenance of customizad versions of ERP systems
ERP systems (Enterprise Resource Planning) have been widely used by companies from many sectors. Although the ERPs are commercialized in the form of information systems ready to be used, companies using ERP have peculiarities that generally represent their competitive differential and they are not fully met by these systems. Changing these systems means incu
