Title: Liofilização de produtos aquáticos: tendências científicas, desafios atuais e influência da geometria de corte na qualidade de filés de tilápia-do-Nilo (Oreochromis niloticus) Autor: Souza, Pauliana Leão de Primeiro orientador: Signor, Altevir Abstract: In this review, we synthesize the literature on the freeze-drying of aquatic products to analyze the current state of research on this topic worldwide. In total, 345 publications met the inclusion criteria. It was observed that, from 1958 onwards, the volume of published studies grew considerably, distributed across 181 journals in the areas of Analytical Chemistry, Biochemistry, and Food Science and Engineering. The journals Food Chemistry (6.96%), International Journal of Biological Macromolecules (2.90%), Journal of Food Science (2.90%), and Journal of the Science of Food and Agriculture (2.90%) concentrated the largest number of publications. The study of freeze-drying in aquatic products has sparked the interest of researchers in 51 countries. However, scientific output has been concentrated in China (21.74%) and the United States (8.70%). In contrast, publications originating from Oceania, Africa, and Central America have remained scarce. Furthermore, although the research covered 12 different types of raw materials, fish (64.68%) was the main target of the investigations. Among the fish species, Nile tilapia (Oreochromis niloticus) was the one with the greatest interest for the application of the freeze-drying method (7.20%) in the studies. There was a predominance of studies involving muscle tissues and their derivatives (41.13%) and protein biomolecules (23.38%). The focus of most of the research was related to the areas of Food Engineering (48.93%) and Analytical Chemistry (17.91%). Predominance observed in most of the countries analyzed. However, although the scope of the studies has changed over the years, most publications have remained in already established areas. Furthermore, research is needed to reduce energy costs and improve equipment, aiming to expand access to freeze-drying in regions where its use is still limited. In addition, it is essential to delve deeper into underexplored fields such as Animal Health and Genetics, as well as investigations into the freeze-drying of aquatic by-products, with the goal of adding value and ensuring the sustainability of the process.

Title: Socioeconomia e qualidade de vida dos pescadores profissionais do entorno do Parque Nacional de Ilha Grande MS/PR, Brasil Autor: Yunes, Rosinara Virginia Ferreira Primeiro orientador: Kashiwaqui, Elaine Antoniassi Luiz Abstract: This research investigates the socioeconomic conditions and quality of life of professional fishers operating in the surroundings of Ilha Grande National Park, located in the Upper Paraná River Basin, a region marked by profound environmental transformations resulting from river damming and the establishment of protected areas. Developed in a multipaper format, the dissertation articulates two complementary empirical studies based on interviews with 59 professional fishers, combining descriptive analysis, content analysis, and multidimensional perceptual assessment. The first study characterizes the socioeconomic and productive profile of these fishers, highlighting the aging of the category, low educational attainment, economic dependence on fishing, declining income, and changes in fish composition associated with historical damming processes along the Paraná River. The second study deepens this analysis by evaluating fishers’ quality of life across economic, social, and environmental dimensions, comparing the fishers’ own perceptions with assessments of institutional governance. The findings reveal significant divergences between these rationalities, indicating that quality of life cannot be understood through isolated or exclusively institutional indicators, but rather as a multidimensional construct shaped by environmental, economic, and social factors, as well as by traditional fishing knowledge. By shedding light on tensions between environmental conservation, public policies, and traditional ways of life, this research contributes to the debate on professional fishing in protected areas and to the formulation of management strategies that are more responsive to the social realities of fishing communities.

Title: Sartre e o paradoxo da morte vivida Autor: Gonçalves, Thiago Sitoni Primeiro orientador: Silva, Claudinei Aparecido de Freitas da Abstract: This ongoing dissertation aims to sustain, within the scope of Sartrean philosophy, the paradox of lived death as a phenomenon that traverses human existence from the very announcement of my death. Our hypothesis consists in examining how we may describe this sui generis event. To that end, we outline our methodological approach in order to understand the itinerary of a prereflective consciousness that is, in Sartrean terms, always oriented by freedom-in-situation. Lived death corresponds to a limit. It is experienced by human reality in the face of itself and is mediated by alterity, which interrogates it through an unreflective conduct in the world, thereby collapsing its imaginary world. To substantiate this hypothesis, we situate the Sartrean dialogue with phenomenology and the prereflective cogito as its point of departure.In the first chapter, we aim to interrogate the phenomenon of death in relation to emotion and imagination, within the spectrum of a magical and embodied dimension of the consciousness–world bond. In a second moment, we examine human conduct through the guiding thread of freedom and, from there, tension intersubjectivity, bad faith, and anguish in Being and Nothingness in order to position the enigma of death within its ontological and ethical incursions. Since our methodological path involves a dual investigation between psychology and literature, we seek to clarify this relation of paradigms in the third chapter. There, we address the existentially grounded psychoanalytic approach and the notion of engaged literature as discussed in What Is Literature?. Across this dual trajectory of analysis concerning human reality, we begin from a “communicating neighborhood” between philosophy and literature and then transition toward psychology and literature, in order to focus on the psychophysical experience of Sartrean characters as a way of understanding the phenomenon of lived death. In the fourth chapter, we describe how the theme of death presents itself to the philosopher within the phenomenological tradition through his critical reading of the Heideggerian existential of being-toward-death. In this section of the dissertation, we mark Sartre’s distinctive stance through the notion of an absurd death—an idea that enables the thesis of the paradoxical existence of a lived death. The relevance of such a thesis lies in fulfilling Sartre’s project of bringing human reality to the forefront through its failure to be God and its impossibility of being a self-caused being. In the fifth and final chapter, we situate the motivation for our choice of The Wall and the notions of being-in-the-world-at-war and “passage” for understanding the characters. Our attention is directed specifically to the drama of Pablo Ibbieta, Tom Steinbock, and Juan Mirbal on the eve of their execution. Through the passage of literature to philosophy, the paradox of lived death emerges from the absurdity of waiting, in which the characters attempt to thematize their own end and find no support other than the radical and fragile contingency of freedom.

Title: A consciência como elemento fundamental da moralidade em Jean-Jacques Rousseau Autor: Santos, Whesley Fagliari dos Primeiro orientador: Antunes , Jadir Abstract: La corruption de l'homme au sein de la société est assurément l'un des grands problèmes que l'on retrouve dans l'œuvre du philosophe genevois Jean-Jacques Rousseau (1712-1778). Dès lors, la question qui guide cette étude est la suivante : est-il possible, selon la pensée de Rousseau, de surmonter les problèmes moraux afin de parvenir à une société dont la composition sociale ne se corrompt pas ? Oui, c'est possible. Par l'éducation. La conscience joue un rôle essentiel dans la structuration et le fondement de la morale. Rousseau illustre ce processus à travers le personnage d'Émile, présenté dans son ouvrage *Émile ou l'Éducation* (1762). Il est donc essentiel d'étudier la théorie de la conscience dans l'œuvre de Rousseau, car le problème que nous présentons dans cette thèse est le suivant : pour que le système éducatif qu'il propose soit viable, la conscience doit servir de base à une redéfinition de la morale et permettre d'éviter la corruption humaine au sein de l'État civil. À cette fin, il est nécessaire d'examiner la définition, l'importance et les implications de la perfectibilité et de la liberté naturelle dans la conception rousseauiste de l'homme dans son état originel et du citoyen dans l'État civil ; de comprendre ainsi comment la volonté particulière et l'amour-propre interagissent avec la volonté générale issue du contrat social ; d'explorer comment la conscience se rapporte à la raison et comment les deux sont liées au système éducatif rousseauiste – d'abord par la pédagogie négative, puis par l'examen de la pédagogie positive ; d'établir les conditions permettant à la conscience de constituer le fondement de la morale et des actions politiques.
