- Apical periodontitis and related risk factors: cross-sectional studyPublication . Correia-Sousa, Joana; Madureira, Ana Raquel; Carvalho, Manuel Fontes; Teles, Ana Moura; Pina-Vaz, IreneObjectives: The aim of this cross-sectional study was to investigate an association between the prevalence of root-filled teeth (RFT) or apical periodontitis (AP) and some systemic conditions or smoking habits in an adult Portuguese population. Methods: Medical histories, including age, gender, presence of cardiovascular disease (CVD), diabetes mellitus (DM), allergies, smoking status, and endodontic treatment data of 421 patients (10,540 teeth) were recorded. The prevalence of root filled teeth and the periapical status were assessed through panoramic radiographies. Periapical status was classified according to the Periapical index and AP was defined as PAI-score ≥3. Statistic analysis was performed with PASW Statistics 20.0 using qui-square tests, odds-ratio and confidence intervals (95%). Results: The overall prevalence of AP and RFT was 2.2% and 4.2%, respectively. RFT increased the possibility of having AP (p< 0.0001). Men's group showed a higher percentage of teeth with AP (p< 0.0001), less RFT (p = 0.05) and more residual roots (2.3%). Smoking increased the probability of having AP (p = 0.002) and RFT (p = 0.045). A positive correlation was observed between RFT and DM (p = 0.040). No statistically significant difference was found between AP and CVD, DM or allergies neither between RTF and CVD or allergies. Conclusions: The higher prevalence of AP and/or RFT in smoker subjects and in diabetic patients can suggest a relationship between oral and systemic health. More epidemiological studies are required before definitive conclusions can be made.

- Science4you, S.A. : from educational toys to software and hardware devicesPublication . Carreira, Pedro Manuel de Nóbrega Moita Coelho; Cardeal, NunoThe thesis that is hereby presented in the form of a case study aims to address the challenges faced by the Portuguese company Science4you, S.A., upon creating a new product line focusing technology products, particularly tablets and smartphones. The thesis is divided into three parts: case study, literature review and teaching notes which can be used as an educational tool in undergraduate or graduate programs. Formed in 2008, Science4you, S.A. is a company dedicated to the development, production and marketing of toys, as well as birthday parties, holiday camps, training courses and scientific animation. Despite not having carried out any market research in concrete, by the end of 2013, Science4you decided to develop a new line of technology products for children (tech4you). Such decision resulted from the company perception that the market lacked this kind of products, which target the needs of children and address parental concerns. The business strategy followed by Sience4you, and the analysis of the strategic option mentioned, constitute interesting topics for discussion which can be reviewed in a strategy course and supported by theoretical concepts proposed in the literature review. The proposed reflection focuses primarily on the analysis and evaluation of the business strategy, including the strategic option of developing a new line of technology products, thus providing recommendations for alternative strategic paths for the future.
