CASE STUDIES ON TRANSPORT POLICY

Abstract
In recent years we have witnessed an increase in the number of parents driving children to school in several developed countries, with increases of, for instance, 35% in the USA, 12% in the United Kingdom and 44% in Australia. These changes have been responsible for several negative impacts ranging from the general increase of Greenhouse Gas emissions and traffic congestion, to more individualized impacts on the health and safety of students. In this context, special attention has been given to introducing mobility management strategies for school trips aimed at creating healthier and more sustainable travel behaviours in students and their parents. Regardless of the vast research, the knowledge on the effects of mobility management measures is still limited, particularly for the soft measures aimed at voluntary travel behaviour change. This paper aims to assess the effects of soft mobility management measures in the travel patterns of pre-university students, namely, Carpooling, Park & Stride, School Route Map, Safe Parking Banners, and the Tree of Life Contest. The assessment of such effects is developed in a particular context, in which the school implementing the measures does not benefit from any institutional or financial support. The research followed the implementation phase during one semester using before and after surveys to assess effects on travel behaviour. This research displayed the difficulties of a school lacking funding and technical expertise in successfully implementing soft mobility measures when compared with other case-studies where government support was provided. Although a direct influence on the mobility patterns due to the implemented measures was not clear, the results suggest that they were able to create awareness and intentions of change, strengthening the role of such measures in increasing sustainable mobility within the student community.

Abstract
Smart device microphone spirometry, based on the audio recording of forced expiratory maneuver (FEM), can be a simple, ubiquitous and easy tool for patients to self-monitor their asthma. Automatic validity assessment is crucial to guarantee that the global effort of the FEM fulfil the admissible minimum or if the maneuver needs to be repeated. In this work an automatic method to classify the sounds from FEM with respect to global effort was developed and evaluated using data from 54 children (5-10 years). The method proposed was able to correctly classify the microphone spirometry with respect to admissible minimum of effort with an accuracy of 86% (specificity 87% and sensitivity 86%). This method can be used to provide immediate feedback of the correct execution of the maneuver, improving the clinical value and utility of this self-monitoring tool.

Abstract
Breast cancer is one of the most common malignanciesaffecting women worldwide. However, despite its incidence trends have increased, the mortality rate has significantly decreased. The primary concern in any cancer treatment is the oncological outcome but, in the case of breast cancer, the surgery aesthetic result has become an important quality indicator for breast cancer patients. In this sense, an adequate surgical planning and prediction tool would empower the patient regarding the treatment decision process, enabling a better communication between the surgeon and the patient and a better understanding of the impact of each surgical option. To develop such tool, it is necessary to create complete 3D model of the breast, integrating both inner and outer breast data. In this review, we thoroughly explore and review the major existing works that address, directly or not, the technical challenges involved in the development of a 3D software planning tool in the field of breast conserving surgery. © 2018 by Begell House, Inc.
