  In our research we studied the economic potential; curbing costs; and elements of these of two woody stemmed invasive species: black locust (Robinia pseudoacacia L.) and tree of heaven (Ailanthus altissima Mill.) in a period 5 years. Questionnaires were sent to the relevant state institutions (national park directorates and state forest companies), other publicly available background information was collected and telephone interviews were carried out to complete the data. During the evaluation of data we found that the costs of black locust reduction were so high in national park directorates that they could not be compensated by the revenue from the sale. However, in the case of state forest companies, incomes were several times higher than costs each year. The judgment of tree of heaven was negative in all areas, so it could not be sold.

  The megatrend of striving for healthy nutrition is a constant and indisputable reality. In our pilot research, we investigated an essential but often overlooked area of nutrition for consumers, focusing on the well-known players in the hydration field: soft drinks. Our study involved a group of 30 high school graduates aged 18-19, who represent a real purchasing power in the food market, and therefore the understanding of the mechanisms behind their purchasing decisions is a key issue. Our primary research was structured along two main pillars, the first was to understand the internal unconscious influences, which we investigated using a fixed eye camera. The second pillar consisted of a questionnaire survey, in which we asked participants about their background, their individual preferences and questions about what they saw during the eye-camera study. Monitoring gaze tracking enabled us to examine what participants were focusing on when they looked at the front or information side of a beverage package. Our research also included an eye-camera analysis of promotional posts on social media platforms. We compared the data collected using the eye camera with the subjective health awareness of the participants and created groups. For each group, aggregated heat maps were created, which provide a visual representation of the distribution of gaze in each image.
