The eye tracking technique is increasingly used in the context of examining the method of processing visual information from instruments and displays located in the cockpit of an airplane. An important aspect is monitoring the pilot's visual behavior in the most difficult phase of the flight, which is the landing of the plane. Six people participated in the research, divided into three groups according to their experience. The subjects performed three landing approaches in various weather conditions. During the study, the visual behavior of the participants was recorded using the Pupil Invisible eye tracker. Based on the analysis of heatmaps and areas of interest, differences in the distribution and number of fixations in the visual field between pilots with different aviation experience were shown.

Technika eye trackingu znajduje coraz szersze zastosowanie w kontekście badania sposobu przetwarzania informacji wizualnych z przyrządów i wyświetlaczy umieszczonych w kokpicie samolotu. Istotnym aspektem staje się monitorowanie zachowania wzrokowego pilota w najtrudniejszej fazie lotu, jaką jest lądowanie samolotu. W badaniach wzięło udział sześć osób, podzielonych względem doświadczenia na trzy grupy. Badani wykonywali trzy podejścia do lądowania w zróżnicowanych warunkach atmosferycznych. Podczas badania rejestrowano zachowanie wzrokowe uczestników przy wykorzystaniu eye trackera Pupil Invisible. Na podstawie analizy map cieplnych oraz obszarów zainteresowania wykazane zostały różnice w rozmieszczeniu oraz liczbie fiksacji w polu wizualnym pomiędzy pilotami o zróżnicowanym doświadczeniu lotniczym.

This article focuses on the human factor in UAV operations. In the manuscript, research on the psychophysical state of student-operators under the license of UAVO VLOS <4 kg. For the analysis of the psychophysical state, the pulse parameter was used, which is one of the values that describe the work of the cardiovascular system and is one for the objective methods of assessing the psychophysical state of a human being. The data collected were analyzed using the STATISTICA software. The article focuses on the above aspect and analyzes the psychophysical state of the student-operator during flight training. The obtained results were also related to research on similar topics in the chapter discussion section.

Artykuł koncentruje się na czynniku ludzkim w operacjach UAV. Przeprowadzono badania stanu psychofizycznego studentów-operatorów na licencji UAVO VLOS <4 kg. Do analizy stanu psychofizycznego wykorzystano parametr tętna, który jest jedną z obiektywnych metod oceny stanu psychofizycznego człowieka. Zebrane dane analizowano za pomocą oprogramowania STATISTICA. Skupiono się na pracy układu sercowo-naczyniowego i przeanalizowano stan psychofizyczny ucznia-operatora podczas szkolenia w locie. Uzyskane wyniki odniesiono również do badań o podobnej tematyce w rozdziale dyskusyjnym.

Drugs administered in chemotherapy influence the patient's hematopoietic system. The side effects of chemotherapy can force changes in both the dose of drugs and the schedule of their administration, which in turn may adversely affect the patient's health. During chemotherapy treatment, there is a necessity to continuously monitor basic blood parameters, including the number of neutrophils and blood platelets, responsible for the patient's immunity. The aim of this paper is to study the behavior of the hematopoietic system, during chemotherapy, by means of a modified mathematical model of neutrophil production. We conducted simulations for children from 1–15 years old, suffering from neuroblastoma, who are undergoing chemotherapy treatment with Topotecan (TPT). The proposed model provides an effective tool for signaling the moment when the number of mature neutrophils, circulating in the blood, drops below the critical level, that is, 500 cells/mL. Such a nadir persisting over time may result in severe neutropenia and consequently require a halt or change to the established treatment schedule. In addition, we analyzed the process of neutrophil production during chemotherapy, supported by the application of glycoprotein as a growth factor of stem cells.
