The object of research is the onboard subsystems of Unmanned Aerial Vehicles (UAVs). The research is aimed at analyzing UAVs, specifically the integration and enhancement of satellite-based positioning systems, including Global Navigation Satellite Systems (GNSS) and Inertial Navigation Systems (INS). The problem concerns traditional satellite-based positioning services, especially those relying solely on medium earth orbit (MEO) satellites, which are insufficient for specific requirements. The study aims to address the limitations of these systems on onboard subsystems of UAVs, especially in challenging environments laden with jammers and interference, and to provide a more accurate, robust, and continuous positioning solution. The research proposes a «multilayer system of systems» approach that integrates signals from various sources, including low Earth orbit (LEO) satellites, ground-based positioning, navigation, and timing (PNT) systems, and user-centric sensors. The combined approach, termed LeGNSS/INS, leverages the strengths of each component, providing redundancy and enhanced accuracy. The system's performance was evaluated using pseudo-real output data, demonstrating its ability to generate quasi-real dynamic trajectories for UAV flight. The error analysis showed that the proposed method consistently outperforms traditional GNSS systems, especially in challenging environments. The enhanced performance of the LeGNSS/INS system can be attributed to integrating multiple satellite systems with INS and applying optimal filtering techniques. The research also employed mathematical modeling to represent the dependencies and interactions when combining data from different sources, such as GPS, LEO, and INS. The Kalman filter is a mechanism to fuse data from multiple sources optimally. The insights from this study apply to various sectors, including aviation, maritime navigation, autonomous drones, and defense. The enhanced positioning accuracy can significantly improve safety, navigation precision, and operational efficiency. However, the study assumes idealized conditions for satellite signal reception, which might not always be accurate in real-world scenarios. Challenges, such as the martial law conditions in Ukraine affecting data collection and potential satellite signal restrictions, were also highlighted. Further research can delve into the impact of more complex environmental factors and the integration of additional satellite systems or sensors to enhance accuracy further.

The study constructs a composite indicator to rank macroeconomic performance of countries and a separate composite indicator to rank countries by inequality using the TOPSIS methodology of Multiple Criteria Decision-Making Analysis. The intuitive idea of TOPSIS is to formulate an ideal solution with respect to each individual policy variable; the relative rank of any country is then determined, using a suitable distance metric, such that the best performer simultaneously has the shortest distance from the ideal solution and the farthest distance from the non-ideal. It uses the composite indicator based rankings together with the KOF Globalization Index and sub-indices based rankings to examine the overall relationship between globalization and macroeconomic performance of countries and reduction in inequality; the impacts of trade and financial globalization for 1990–2018 across countries and groups of the globe. It shows that though highly correlated with growth, globalization may not necessarily lead to an improvement in overall macroeconomic performances of countries when one also takes into account unemployment and inflation. Economic globalization is seen here to mostly coincide with rise in income inequality. Observations also support the fact that countries, even if they are not highly integrated may reap sufficient benefits of globalization for macroeconomic performance and inequality diminution given supportive policies.

O câncer é uma patologia que pode interferir de forma significativa na vida do sujeito e de seu familiar/cuidador. Neste contexto, surge a Psico-oncologia, uma área de interface entre a Psicologia e a Oncologia. O presente estudo busca analisar o papel da Psico-oncologia na trajetória do doente e de sua família no processo de adoecimento do câncer. Para tanto, foi realizada uma pesquisa bibliográfica, através da busca ativa de informações em livros, revistas e artigos acadêmicos. A partir do levantamento da literatura revisada, destacamos que a atuação do psicólogo no cuidado oncológico se dá por meio do apoio psicossocial e psicoterapêutico através de grupos de apoios, acolhimento, assistência, escuta, entre outras práticas, visando propiciar um melhor enfrentamento da doença entre os envolvidos. De modo geral, pode-se inferir que a Psico-oncologia é uma ferramenta contemporânea e indispensável na promoção da qualidade de vida ao paciente com câncer, a sua família e à equipe que o acompanha.

Voici plus d'un demi-sicle naissait une des principales revues francophones de gographie, partir d'une base multirgionale et avec l'ambition, au-del de l'Ouest de la France, de s'intresser au domaine du Nord-Ouest europen, aux diffrents pays riverains des mers bordires de l'Atlantique Nord, l'espace ocanique, aux domaines arctiques. Paul Fnelon a relat comment fut choisi, en partie son initiative, le titre de Norois, en rfrence la fois au Norouet, le vent de nord-ouest des marins bretons et, par le prisme de Leconte de Lisle dans La mort de Sigur , aux Norrains, hardis monteurs de nefs qui dcouvrirent et parcoururent ce vaste domaine de l'Atlantique Nord (Fnelon, 1987, p. 13). Rappelons galement que le sous-titre retenu n'tait pas sans voquer les titres d'autres revues dites rgionales de gographie et que l'espace considr tait pour partie couvert par le trait de l'Alliance Atlantique.
