Hypoxia remains a flight-safety issue in terms of aviation medicine. Hypoxia-awareness training has been used to help aircrew members recognize personal hypoxia symptoms. There is still no study, as yet, to establish the association of within-subject data between inflight hypoxia events and the altitude chamber. The main purpose of our study was to use paired subjects’ data on inflight hypoxia symptoms compared with those experienced during training. A questionnaire was developed to obtain information on military aircrew members in 2018. Among 341 subjects, 46 (13.49%) suffered from inflight hypoxia. The majority of the subjects detected ongoing inflight hypoxia on the basis of their previous experience with personal hypoxia symptoms or sensations in previous chamber flights. Of the top five hypoxia symptoms, the data revealed that hot flashes, poor concentration, and impaired cognitive function appeared both during the inflight events and during the hypoxia-awareness training. The occurrence rate of hypoxia symptoms was found to not be significantly different between the in-flight events and the past chamber flights through an analysis of within-subject data. Because the individual memory had faded away over time, fresher hypoxia awareness training is still mandatory and valuable to recall personal hypoxia experience for military aircrew members.

O presente artigo se debruça sobre a obra da jornalista e escritora ucraniana/bielorrussa Svetlana Aleksiévitch, ganhadora do Nobel de Literatura de 2015. Composta por milhares de testemunhos traumáticos, a obra se propõe escrever a história do “pequeno homem soviético” de maneira sensível, dando à memória individual valor reconstitutivo da experiência passada, de modo ao componente “memória” ser associado à “verdade”. Assim, com um olhar literário, e não historiográfico, a autora opõe, política e existencialmente, a memória biográfica à “gloriosa história da Vitória soviética”. Assim, busca-se investigar metodologicamente os usos da memória enquanto fonte em sua narrativa e trazer, a partir de uma preocupação biográfica, corporal e sensível, problematizações linguísticas e epistemológicas para a escrita da história contemporânea.Palavras-chave: Svetlana Aleksiévitch; Memória soviética; Linguagem; Escrita da história.Abstract The present paper aims at reflecting about the work of the ucranian/bielorussian journalist and writer Svetlana Aleksiévitch, winner of the 2015 Nobel of Literature. Composed by thousands of traumatic testimonials, her book proposes to write the history of the “little Sovietic man” in a sensitive way, giving the individual memory a reconstitutable value over the past experiences, in a way that “memory” is associated to “truth”. Thus, not within an historiographical perspective, but rather through a literary one, the author opposes, politically and existentially, a biographical memory to the “glorious history of the Soviet victory”. On these grounds, this paper targets to investigate methodologically the uses of memory as a source in Aleksiévitch’s narrative, and also to bring, through a biographical, corporal and sensible preoccupation, linguistical and epistemological questionings to the process of contemporary historical writing.Keywords: Svetlana Aleksiévich; Soviet memory; Language; Writing of history.

30 years have passed since the events of 1989 that led to the collapse of communism in Central and Eastern Europe. In the paper the themes of social memory of political transformation in Poland in 1989 are discussed. The content of online statements collected from popular Polish news portals are analysed. When asking the question what events and experiences do Poles bring back when they think of 1989, I am interested in the relationship between the individual (biographical) memory and collective memory – the socially reconstructed knowledge of the past.

Tuvia Ruebner’s postcard poems undermine the stereotypical, commercial image that tourist postcards wish to create. The name of the poem and the structure hint at such postcards, but attempt to change their appearance, to broaden the limits of the present, and integrate the past into it. The poet offers a memento that combines presence and absence, what is visual and what is verbal, and an inner and an outer reality. The individual memory is thus woven into a collective memory. These poems offer a sober worldview where Europe turns out to be the source of pain and longing, alongside great joys and pleasures. Ruebner’s postcard poems subvert the normative boundaries and binary divisions, providing the reader with a deeper look at human nature, and at the workings of memory.

In the works of Ludwig Bauer, a significant place is given to the autobiographical memory of the past, strongly connected with the discourse of identity, lost childhood, collective amnesia; it is related to body memory, place memory, and in the characters’ biographies there is usually present (overt or covert) Plato’s eikon (seen as a trace imprinted on the psyche and the mind), whose finding and explaining stimulates the plot and the story. Community memory is stored (A. Assmann) in the individual memory of its members. The aim of the proposed topic is to explore — with the use of interdisciplinary, methodological achievements in the field of memory discourse — the hermeneut-ics of L. Bauer’s selected works. As a result, the disquisition provides an analysis of literature in the process of forming memory and identity in the area of the former Yugoslavia, as well as literature as a medium of memory and “distinctive symbol system” (B. Neumann) in the whole culture of memory.

The individual and collective discussions of the patient safety issue in the United States have mounted from a low roar to a deafening din in the past 10 years. In this chapter the authors (1) discuss the context of patient safety over the past decade and the federal response to the problem, (2) briefly present Reason’s theory of human error, which frames much of the safety research, and (3) provide a glossary of terms.

The aim of the article is to concretize the concept of political ideology in the aspect of its matrix structure and in the context of the cognitive-evolutionary approach. Based on Michael Frieden's morphological approach to the analysis of ideological consciousness, the concept of cognitive-ideological matrices is introduced, which allows us to describe the process of transition from proto-ideological to ideological concepts proper, especially at the level of individual consciousness. The identification of the ideological concept as the main “gene” of conceptual variability and inheritance made it possible to describe the main parameters of the evolution of political ideologies and associate it with changes taking place at the individual consciousness level. The described concept was tested in a series of sociological studies of youth consciousness conducted in 2015-2016 and 2018-2020. As a result of the study, it was possible to first identify the “zero level” of ideology, at which the minds of young respondents are potentially open to the influence of diverse and often mutually exclusive ideological orientations, and second, to pinpoint the changes that have occurred in the cognitive ideological matrices of Rostov-on-Don students over the past five years. This study was conducted by scientists from the southern Federal University.

Traditionally, natural medicines have been administered as plant extracts, which are composed of a mixture of molecules. The individual molecular species in this mixture may or may not contribute to the overall medicinal effects and some may even oppose the beneficial activity of others. To better control therapeutic effects, studies that characterized specific molecules and describe their individual activity that have been performed over the past decades. These studies appear to underline that natural products are particularly effective as antioxidants and anti-inflammatory agents. In this systematic review we aimed to identify potent anti-inflammatory natural products and relate their efficacy to their chemical structure and physicochemical properties. To identify these compounds, we performed a comprehensive literature search to find those studies, in which a dose-response description and a positive control reference compound was used to benchmark the observed activity. Of the analyzed papers, 7% of initially selected studies met these requirements and were subjected to further analysis. This analysis revealed that most selected natural products indeed appeared to possess anti-inflammatory activities, in particular anti-oxidative properties. In addition, 14% of the natural products outperformed the remaining natural products in all tested assays and are attractive candidates as new anti-inflammatory agents.

Temporal focus is the individual tendency to characteristically think more or less about the past, present, and future. Although originally rooted in early work from psychology, research on temporal focus has been steadily growing in a number of research areas, particularly since Zimbardo and Boyd’s (1999) influential article on the topic. This chapter will review temporal focus research from the past to the present, including how temporal focus has been conceptualized and measured, and which correlates and outcomes have been tested in terms of well-being and behavior. Based on this review, an agenda for research is created to direct temporal focus research in the future.

Abstract Background The larynx has multiple composite functions which include phonation, airway protection, and sensory control of respiration. Stenosis of the larynx and trachea were first recorded by O’Dwyer in 1885 and by Colles in 1886, respectively. Initially, the aetiology of laryngotracheal stenosis was predominantly infective. Currently, the leading cause is iatrogenic injury to the laryngotracheal complex secondary to prolonged ventilation in an intensive care unit. Main body Laryngotracheal stenosis is a complex and diverse disease. It poses a major challenge to the surgeon and can present as an airway emergency. Management typically demands the combined involvement of various disciplines including otorhinolaryngology, cardiothoracic surgery, anaesthesiology, interventional pulmonology, and radiology. Both the disease and its management can impact upon respiration, voice, and swallowing. The incidence of iatrogenic laryngotracheal stenosis has reflected the evolution of airway and intensive care whilst airway surgery has advanced concurrently over the past century. Correction of laryngotracheal stenosis requires expansion of the airway lumen; this is achieved by either endoscopic or open surgery. We review the relevant basic science, aetiopathogenesis, diagnosis, management, and treatment outcomes of LTS. Conclusion The choice of surgical procedure in the management of laryngotracheal stenosis is often dictated by the individual anatomy and function of the larynx and trachea, together with patient factors and available facilities. Regardless of how the surgeon chooses to approach these lesions, prevention of iatrogenic laryngotracheal damage remains of primary importance.
