Termografia, jako nieinwazyjna metoda pozwalająca szybko i skutecznie wykryć obszary o podwyższonej temperaturze powierzchni ciała, idealnie nadaje się do celów wspomagających diagnostykę schorzeń piersi. Celem przeprowadzonych badań było udoskonalenie procedur badawczych z wykorzystaniem termowizji poprzez zastosowanie wstępnego schłodzenia ciała ochotników. Pomiary wykonano w Laboratorium Medycyny Sportowej Instytutu Inżynierii Biomedycznej na Uniwersytecie Śląskim. Grupa badawcza składała się z 5 zdrowych, młodych osób. Ciało ochotników zostało schłodzone w komorze kriogenicznej CrioSpace firmy JBG2 przy pomocy powietrza o temperaturze 0°C. Na uzyskanych termogramach gruczołów piersiowych oznaczone zostały obszary pomiarowe według stosowanej w medycynie konwencji. Analizowane termogramy oraz parametry temperaturowe jednoznacznie wykazały zwiększenie zakresu obserwowanych różnic temperaturowych po schłodzeniu piersi. Kontrast temperaturowy obliczany na podstawie różnic średnich temperatur symetrycznych obszarów piersi wzrastał nawet kilkakrotnie. Prosty zabieg ochłodzenia badanego obszaru może zatem podnieść czułość i dokładność pomiarów termowizyjnych.

Thermography as a non-invasive method that allows to detect quickly and effectively areas with increased body surface temperature, is ideally suited for supporting the diagnosis of breast diseases. The aim of the research was to improve research procedures using thermovision by applying pre-cooling of the volunteers’ bodies. The measurements were made at the Sports Medicine Laboratory of the Institute of Biomedical Engineering at the University of Silesia. The research group consisted of 5 healthy young people. The body of the volunteers was cooled in the CryoSpace cryogenic chamber by JBG2, with the use of air at a temperature of 0℃. Measurement areas were marked on the obtained thermographs of the mammary glands according to the convention used in medicine. The analysed thermograms and temperature parameters clearly showed an increase in the range of observed temperature differences after breast cooling. The temperature contrast, calculated on the basis of differences in mean temperatures of symmetrical breast areas, increased even several times. A simple treatment of cooling the examined area can therefore increase the sensitivity and accuracy of thermal imaging measurements.

Purpose: The aim of the study was to diagnose attitudes and consumption behaviors among the young adults, regarding food consumption in Poland. Design/methodology/approach: 483 respondents took a part in the research. They were students of three Cracovian universities, representing all voivodships in Poland. The research instrument consisted of two types of questions: traditional closed survey questions and a series of projection questions, based on fictional characters, which the respondents had to assess and determine the degree of identification with the attitudes and behaviors described. Findings: The research revealed some akrasia. The relatively high level of awareness regarding the effects of unsustainable production and consumption of young adults did not translate into consumption behavior of a sustainable nature. The curiosity regarding origin of the product and its composition turned out to be low, as was the feeling of responsibility for their own decisions. There was a tendency to expect the transition of responsibility to food producers and the institutional environment. Young adults pay special attention to food prices and easy access to shopping. Local marketplaces are a niche shopping place. The majority of food is purchased in large-area stores, where consumers are not informed about the place of origin of food. The respondents group is characterized by high outside-diagonality, solutions forcing more sustainable behavior, for example, the payment for plastic bags, the need for recycling of waste meet with wide acceptance. Originality/value: The research revealed enforcing proecological behaviors by institutions seems to be a more effective than building consumer awareness.
