This paper examines the operational consequences and energy demands associated with the growing cultural diversity of air travellers at airport security checkpoints. The analysis focuses on how an increasing proportion of passengers requiring enhanced security screening, due to cultural, religious, or linguistic factors, affects both system throughput and energy consumption. The methodology integrates synchronised measurement of passenger flow with real-time monitoring of electricity usage. Four operational scenarios, representing incremental shares (0–15%) of passengers subject to extended screening, were modelled. The findings indicate that a 15% increase in this passenger group leads to a statistically significant rise in average power consumption per device (3.5%), a total energy usage increase exceeding 4%, and an extension of average service time by 0.6%—the cumulative effect results in a substantial annual contribution to the airport’s carbon footprint. The results also reveal a higher frequency and intensity of power consumption peaks, emphasising the need for advanced infrastructure management. The study emphasises the significance of predictive analytics, dynamic resource allocation, and the implementation of energy-efficient technologies. Furthermore, systematic intercultural competency training is recommended for security staff. These insights provide a scientific basis for optimising airport security operations amid increasing passenger heterogeneity.

The young Polish anthropologist Stanisław Poniatowski undertook fieldwork in the Russian Far East in summer 1914. He collected almost five hundred various artifacts (objects, photographs, anthropometric measurement forms, etc.) and linguistic material from the local Nanai and Udege communities along the Amur River. The outbreak of World War I changed Poniatowski's plans and caused the separation (fragmentation) of his original collections, now housed at the Polish Ethnological Society in Wrocław, Poland and at the Smithsonian Institution in Washington, DC in the US. The article describes a new multistep effort to digitally “reunite” Poniatowski's collections and convert them into a cultural resource for researchers, museum specialists, and Indigenous communities for heritage and language preservation.
