- Breast Skin Temperature Evaluation in Lactating and Non-lactating Women by Thermography: An Exploratory StudyPublication . Gouveia, Ana; Pires, Luís Carlos Carvalho; Garcia, Nuno; Barbosa, Ana; Jesus, Ana; Pombo, Nuno; Soares, Marta; Oliveira, J. Martinez deDuring pregnancy and lactation, woman breasts feel changes like blood flow increasement, associated with a higher breast temperature. We performed an exploratory study of the breast skin temperature of lactating and non-lactating women based on thermography, with a qualitative analysis of the temperature patterns and a quantitative evaluation of the differences. Frontal breast thermograms of four non-lactating young women and four women with well-established lactation were acquired and analyzed. Qualitative analysis of the images obtained show some evidence of the existence of a characteristic skin temperature pattern for lactating women. Quantitative differences between thermograms were also noticed, especially when considering dispersion metrics: lactating women present higher breast skin temperature gradients and amplitudes. Results obtained, especially based on central tendency metrics, should be interpreted with caution because some of the acquisition conditions for non-lactating women may lead to some bias on the results. Further investigation will be performed to quantify breast skin temperature gradient and be able to classify images based in the breast skin temperature pattern.
- Livestock real-time vital signs monitoring systemPublication . Reigones, Ana Rita Runa da Silva; Gaspar, Pedro Dinis; Garcia, NunoThe focus on the application of information and communication technologies and electronic (ICTE) in agriculture has proven to be very efficient and revolutionary. With the adoption of increasingly efficient and modern technologies, agriculture generally improves its competitiveness and production sustainability. The intensive use of ICTE in this sector aims to create integrated solutions that generate effective gains in productivity, sustainability and economic, social and environmental quality. In this paper is proposed an ICTE-based cattle or horse monitoring system, developed as a belt containing a microcontroller device used to assess the animal's heart rate and detect abnormal mobility. Correct assessment of these two parameters is very useful for detecting many of the pathologies and anomalies that constitute economic losses for producers. With precise monitoring, it is possible to minimize these events detrimental to animal production.
