Series Title : Advances in intelligent systems and computing, vol. 275, The technological evolution verified in recent years caused an increase in the number of therapeutic and diagnostic tests prescribed/performed that led to an exponential growth in the amount of data generated. In the particular case of endoscopy, the data resulting from the procedure is not stored, disallowing their use for future consultation or research purposes and thus forcing the repetition, sometimes unnecessary, of the exam. In order to overcome these issues, an archiving system was developed based on a NoSQL database. The proposed system is supported by a distributed architecture comprising different health care institutions and allows the archiving and replication of the produced examinations. Therefore, the system allows transparent and ubiquitous access to these exams that often correspond to large media files., This work is funded by ERDF - European Regional Development Fund through the COMPETE Programme (operational programme for competitiveness) and by Nation- al Funds through the FCT - Fundação para a Ciência e a Tecnologia (Portuguese Foundation for Science and Technology) within project FCOMP-01-0202-FEDER- 013853.

Global information management, to Hunter (U. of Lethbridge, Canada) and Tan (Auckland U. of Technology, New Zealand), "involves all aspects of the management of information systems in an international setting" and therefore has a diverse research agenda, as displayed in the contents of these 18 contributions examining information management in global and regional settings. Specific topics include retention of online customers; the relationship between culture, information technology, and empowerment; the cross-cultural impact of information system managers' performance, job satisfaction, and managerial value; and adoption of electronic data interchange in small- and medium-sized enterprises.
