The existence is substantially coexistence. Sharing does not detract the loneliness of fall and destiny (guilt and consistence) from his existence these days, the regression into dust (end of experience) fights for human dignity in the Shared Phenomena of Old Age and Dying, which step out from their inconspicuousness and are mirror to the (un)hiddenness of possibilities of authenticity and the phenomenon of Dead in the background of Worry. Existencially-existencial connection of human existence expose that the appetence (the reality) of the First Man, based on the anxiety )possibility of Dead) of the historically last Man of the present, becomes a historical trace of authenticity in the sense of unique horizontal possibilities. Keywords: authenticity, Heidegger, Hogen, ontology, existence, death.

This diploma thesis focuses on validation of RP–HPLC method for determination of organic acids in fruit juices. The aim of this thesis was to determine suitability of the method for verification of the fruit juices authenticity based on analysis of organic acids. The theoretical part describes chemical composition of fruit and fruit juices and focuses on organic acids. It provides description of various methods of organic acids analysis with more detailed description of High Performance Liquid Chromatography and its validation. The experimental part focuses on optimalization and validation of the method. Samples of malic, citric, succinic and ascorbic acid were analysed. The optimalized method was validated and following performance parameters were determined: repeatability, linearity, limit of detection (LOD) limit of quantitation (LOQ). RP–HPLC method was applied to real samples of 100% fruit juices (apple, orange and grapefruit) and the authenticity parameters were verified.

The thesis deals with the issue of authentic or inauthentic work of art in the context of philosophy of authentic / inauthentic mode of existence (Dasein) as it was developed by Martin Heidegger in his Time and Being. The reason for addressing this issue is an effort to open the possibility of understanding authenticity or inauthenticity of individual Dasein in the manner which grasps it in the act of its performance, i.e. as a singular event. Thinking of authentic / inauthentic work of art demonstrates the limits of approach which understands authenticity only as certain originality or "selfness" which should belong to something authentic or inauthentic, almost like its accident. This thesis is therefore concerned with what is revealed if the concept of authenticity is transposed to a work of art. Since it is the subject who can make the act of performance of authenticity happen, the author and the recipient of the authentic / inauthentic work of art are problematized as well. When dealing with the work of art with respect to its temporality (historicality) or its being, the thesis also provides room for the issue of perception of the work of art. The resemblance of the author and the recipient is thus revealed and so is the necessity to learn to see not only artworks as such but to see them...

The work is focused on the evolution of Patočka's conception of movements of the human existence throughout his thoughts. My aim is to show sources of this conception, its explicite expressions and their structure and finally the meaning of this conception for the human life and its status in Patočka's whole-life philosophical project, all this by the analysis of three metodologically defined periods of Patočka's work. The inevitable past of this kind of rethinking of Patočka's conception is dealing with the question of succesion of his two great teachers, Edmund Husserl and Martin Heidegger,and showing, that his conception of movements of the human existence can't be explained simply from the polarity of uncritical bulilding on them, neither the complete refusing them. Also I would like to show the conceptional kinship with other thinkers of western philosophical tradition, whose selection is selective, but in my opinion meaningful. I also hope, that this rethinking of the conception of movements of the human existance will show the place, which belongs to Patočka's thougt in the western philosophical tradition and, first of all, it's meaning for human life. Key words Phenomenology, movement, existence, philosophy of history, authenticity

Prague as space, inside of which music of various genres is being created and performed, linked to different values, being created on foundations of distinct concepts and serving as a medium of various strategies, is characterized by fluid and difficult to grasp soundscape (Shellemay 2006). This environment allows the creation and negotiation of traditions (Glassie 1995), moving into different directions. One of them, which have a recursive character and serves its actors as the construction of meaning and carrying out sociocultural change for its actors, is connected with the concept of folklore. The presented fieldwork examines this part of contemporary Prague soundscape in the field, framed by one of the music and dance events. The regular event, named by the organizers "Folklorní mejdlo", defines itself as a connection of the world of modernity, which is currently offered in the metropolis, and the world of traditions, authenticity and folklore. The fieldwork aims its focus on the way the concepts of authenticity and legitimacy are negotiated, its assigning to individual actors and objects and generally how the actors of the event undertake the construction of folklore and how the final product looks like. This work, with its approach to music as a social act (Turino 2008) endorses the...

This thesis deals with six texts by two of the best-known contemporary American novelists, namely Paul Auster and Thomas Pynchon. The thesis analyzes three most recent novels by each writer: Invisible, Sunset Park and 4 3 2 1 by Paul Auster and Against the Day, Inherent Vice and Bleeding Edge by Thomas Pynchon. All six novels explore various modes of authenticity - a notion which in each author's work adopts specific mechanisms of establishing ways of existing within the world that are directed towards a critique of the forms of society that try to limit individuals, confine them to prescribed objective categories. Chapters I to IV establish one by one the primary approaches to understanding how authenticity works within individual novels. First two chapters explore Paul Auster's works, and emphasize their portrayal of change as an organizing leitmotif. Chapters III and IV deal with selected works by Thomas Pynchon and analyze their use of entropy and information overload within individual narratives. The final chapter then combines all these notions and provides a comparative analysis and a critical interpretation of all six works against a theoretical and critical framework. The thesis explores the differences between Auster's and Pynchon's approach to authenticity, notions of the subjective or the...

Our dissertation thesis Psychotherapy as education for authenticity - Life-world as a psychotherapeutic problem deals with ontological foundations of psychotherapy. We present the change of understanding of a man and the world from antiquity to now. Psychotherapy as a new discipline is based on subject - object understanding and tries to understand human being from this perspective which changes into internal conflict. We consider that psychotherapy and psychology aren't aware of their ontological foundations. The core of this work is based on principles of Husserl's phenomenology and Heidegger's fundamental ontology as conditions of natural psychotherapy. They both bring appropriate understanding of human being. Therefore we consider basic principles of natural psychotherapy. Keywords: Life - World, psychotherapy, authenticity, ontology, education, time

The thesis points to the negative phenomenon of Holocaust denial, objective viewpoint of testimony, authenticity of photograph and background of historical consciousness in the context of postmodern situation. If we wanted to use objective testimony of photograph as a valid argument against Holocaust denial, we would have to declare the authenticity of photograph is invalid. The options of its manipulation, both content and meaning, are examined through semiotics of Peirce, mainly through trichotomy icon, index and symbol. In today's pluralistic time, the historical consciousness is proposed as a possible starting point of examination of historical sources, including photograph. Key words Photograph, authenticity, manipulation, Peirce, historical consciousness, Holocaust.
