INFORMATION SYSTEMS AND TECHNOLOGIES
Abstract
Although IT governance practices (like ITIL, which recommends on the use of Audit Trails (AT) for proper service level management) are being introduced in many Hospitals to cope with increasing levels of information quality and safety requirements, the standard maturity levels of hospital IT departments is still not enough to reach the level of frequent use of AT. This paper aims to address the issues related to the existence and quality of AT in Hospital Information Systems (HIS). A total of 5 hospitals participated in the study (4 CIO interviews and 7 AT from 4 hospitals). Very few AT are known to exist in these hospitals (about 1 per hospital in an estimate of 21 existing IS). The existing AT has poor quality (garbled, incomplete and misformatted information). CIOs should be much more concerned with the existence, quality and maintenance of AT. Recommendations include server clock synchronization, using advanced AT visualization tools, using also real-time auditing tools, and periodically audit the access to all data of a random patient.

Abstract
In this work we build the first BI-RADS parser for Portuguese free texts, modeled after existing approaches to extract BI-RADS features from English medical records. Our concept finder uses a semantic grammar based on the BI-RADS lexicon and on iterative transferred expert knowledge. We compare the performance of our algorithm to manual annotation by a specialist in mammography. Our results show that our parser's performance is comparable to the manual method. © 2012 IEEE.

Abstract
The lack of data in Portugal is a crucial problem for a full characterization and thus a full digital integration for people with disabilities. This is not only a problem of ethic dimension or equal opportunities but have also an economic dimension because excludes a consumer group with economical potential. Hence, this article focuses on the importance of the characterization of people with disabilities in a social, economic and digital perspective. It aims to emphasize their disabilities and ageing evolution, potential value in the digital business and design awareness for inclusion for improve the quality of life of people with disabilities.

Abstract
This paper describes a tool for checking secure information flow in Java Card applications. The tool performs a static analysis of Java Card CAP files and includes a CAP viewer. The analysis is based on the theory of abstract interpretation and on a multi-level security policy assignment. Actual values of variables are abstracted into security levels, and bytecode instructions are executed over an abstract domain. The tool can be used for discovering security issues due to explicit or implicit information flows and for checking security properties of Java Card applications downloaded from untrusted sources.
