Abstract
The activities and skills of the information systems manager evolved extraordinarily in the last half century, from the technician who managed an operational function with a limited importance to the organization, to the position chief information officer, now responsible for a department on which depends the overall success of the organization. This study provides some empirical insight on the chief information officer profession in Portugal. We conducted a survey directed to the chief information officers of Portuguese largest organizations to investigate how they spend their time and to evaluate which are the most important skills for the role they play on the organization. We also compare the results obtained with other studies to try to unveil which differences exist in the activities performed by Portuguese chief information officers and chief information officers from other countries. This study can also be viewed as a guideline for the development and training of existing chief information officers as well as for hiring new managers for this position with the right skills, to assure the right management of information systems.

Abstract
The purpose of the described system is to aid radiologists on their daily routine in the task of analyzing HRCT lung images and to contribute to a more accurate and fast diagnosis. We developed a framework - Study Lung Tool-with the objective of gather information from radiologists, in a systematic way. Using Study Lung Tool framework, the radiologist analyzes HRCT scans, outlines regions of typical pattern and characterizes the patterns. A database of typical patterns associated with common pulmonary diseases was created. The information gathered can be a valuable teaching tool to every one that intends to understand HRCT lung parenchyma. The proposed system discriminates between normal and abnormal patterns of lung parenchyma based on statistical texture analysis extracted from HRCT lung scans. An overall accuracy of 89,2%, a sensitivity of 92,7% and a specificity of 83,6% were achieved.

Abstract
Companies use multiple solutions of information technologies and information systems to support their activities. Among the systems adopted by companies we can find Enterprise Resource Planning systems, Customer Relationship Management systems, Business Intelligence systems and many others. Such systems assure a wide spectrum of activities, ranging from operational support to the strategic support of the company. With the purpose of identifying and characterizing which systems the large Portuguese companies have been implementing, in which systems they intend to invest in short-term and which is the current role of information technology in the organization, we developed a study with the participation of several chief information officers. The findings of this study reveal that in Portuguese large companies the adoption of Enterprise Resource Planning systems are consolidated, while the adoption of systems like Business Intelligence, Collaboration, Workflow and Groupware will increase in the near future.

Abstract
Promoting a healthy lifestyle, including the practice of sport activities, is a very topical subject. In this paper, we present a project related to a game that allows two or more players to take part in competitive running using a simulator consisting of physical equipment, a fixed bike, a controller and a supervisor program. The main goal is the promotion of sports through computer games. © 2011 AISTI.

Abstract
The complexity of Information Technology and Information Systems within organizations keeps growing rapidly. As a result, the work of the Chief Information Officer is becoming increasingly difficult, since he has to manage multiple technologies and perform several activities of different nature. In this position paper, we prove the development of a new tool for Chief Information Officers, which will systematize and aggregate the enterprise Information Systems Function information.

Abstract
In this paper is presented a project -CAD Lung System- whose objective is to help radiologists in their daily routine, in the HRCT images analysis of lung parenchyma. A database of abnormal lung patterns and their reliable classification is a determinant part of the system. We developed a framework -Study Lung Tool- with the objective of gather information from radiologist, in a systematic way. Using this framework, the radiologist analyses HRCT scans, outlines regions of typical pattern and characterizes the pattern. This framework can also be used as a learning tool through the observation of the HRCT scans previously characterized by experts.
