Bachelorarbeit aus dem Jahr 2021 im Fachbereich Medizin - Sonstiges, Note: 1,3, Fliedner Fachhochschule Düsseldorf, Veranstaltung: Pädagogik für den Rettungsdienst, Sprache: Deutsch, Abstract: Der Beruf der Notfallsanitäter_Innen ist ein Meilenstein auf dem Weg zu einer Professionalisierung des Rettungsdienstes, welcher gleichzeitig mit einem großen Kompetenz- und Verantwortungsgewinn verbunden ist. In diesem Rahmen sind die Notfallsanitäter_Innen verpflichtet, eigenverantwortlich invasive Maßnahmen durchzuführen, wodurch auch die Gefahr aufkommen kann, die Patientensicherheit mit den neuen Möglichkeiten zu gefährden.Durch diese Literaturarbeit möchte der Autor den Nutzen eines Critical Incident Reporting System identifizieren und eine Verbindung zur präklinischen Patientensicherheit bei der Behandlung durch Notfallsanitäter_Innen herstellen. Dabei steht der pädagogische Lernansatz mit einer offenen Fehlerkultur im Vordergrund.Bei dieser integrativen Literaturarbeit ist eine Recherche internationaler Literatur durchgeführt worden. Der Ausschluss von Studien wird mittels Prisma Flow Diagramm dargestellt. Mit Hilfe der qualitativen Inhaltsanalyse nach Elo und Kyngäs (2008) wurden die Studien offen kodiert, in Kategorien eingeteilt und induktiv abstrahiert. Abschließend wurde die Studienqualität anhand von Dixon-Woods (2006) auf ihre Güte hin beurteilt.Es konnten 15 Publikationen identifiziert werden. Hier stellten 12 einen direkten Bezug zur präklinischen Versorgung dar. Die Studien legen nahe, dass das Personal in knapp ⅔ aller Fälle für vermeidbare, fehlerhafte Handlungen verantwortlich ist. Ein anonymes Critical Incident Reporting System hilft Fehlermuster und -ursachen aufzudecken, sowie organisatorische Sicherheitsrisiken festzustellen. Der Autor regt an, dass eine offene Fehlerkultur eingeführt und gelebt werden müsste, um Lern- und Lösungsansätze zu suchen und das „Name-Blame-Shame-Paradigma“ zu beenden.Ein anonymes Fehlermeldesystem kann organisatorische Schwachstellen aufzeigen, woraus sich Chancen für ein bisher ungenutztes Verbesserungspotential ergeben. Kommunikation und Umgang mit Medikamenten sind Fehlerschwerpunkte, die sich mit Aus- und Fortbildung verhindern lassen. Ein offener Umgang mit Fehlern kann die Patientensicherheit steigern.

Studienarbeit aus dem Jahr 2023 im Fachbereich Gesundheit - Gesundheitswesen, Note: 1,3, Fliedner Fachhochschule Düsseldorf, Sprache: Deutsch, Abstract: Der § 2a NotSanG ist eine weitere wichtige Veränderung auf dem Weg zu einer Professionalisierung des Rettungsdienstes, welcher gleichzeitig mit einem großen Kompetenz- und Verantwortungsgewinn für die Notfallsanitäter_Innen verbunden ist. Diese Akademisierung im Rettungswesen scheint im Widerspruch mit dem vorherrschenden regionalen Fachkräftemangel zu stehen. Tatsächlich verdrängen akademische Führungskräfte im Rettungswesen nicht die Fachkräfte, sondern sie fördern deren Bestand und die Attraktivität der Berufe im Rettungswesen durch den teamorientierten Führungsstil der Servant Leadership, den vor allem die Generation Y und Z präferiert. Die Arbeit verwendet die Methode der Internetbasierten Literaturrecherche. Ergebnisse. Die neue altruistische Führungsweise durch akademisch ausgebildetes Fachpersonal verbessert die flächendeckende Versorgung der Bevölkerung, indem es durch teambildende und teambindende Maßnahmen bei gleichzeitig hoch qualifiziertem notfallmedizinischem Können und einem ehrenwerten Selbstverständnis von Verantwortung einen kontinuierlichen Fachpersonalbestand sicherstellt. Die Hinwendung an die Bindung der Mitarbeiter_Innen durch eine neue Generation akademisch gebildeter Führungskräfte ist das A und O der Attraktivität von Berufen im Gesundheitswesen, weshalb die Akademisierung des Gesundheitswesens ausdrücklich zu begrüßen ist.

Studienarbeit aus dem Jahr 2022 im Fachbereich Gesundheit - Gesundheitswesen, Note: 1,0, Fliedner Fachhochschule Düsseldorf, Sprache: Deutsch, Abstract: Durch diese Literaturarbeit in Form einer Hausarbeit möchte der Autor den neuen § 2a NotSanG anhand eines realistischen Sachverhaltes strafrechtlich analysieren. In dem Sachverhalt geht es um einen Traumapatienten, der nach Einwilligung von einem Notfallsanitäter das Betäubungsmittel Fentanyl zur Analgesie verabreicht bekommt.Der § 2a NotSanG ist eine weitere wichtige Veränderung auf dem Weg zu einer Professionalisierung des Rettungsdienstes, welcher gleichzeitig mit einem großen Kompetenz- und Verantwortungsgewinn für die Notfallsanitäter_Innen verbunden ist. In bis zu 54% aller Einsätze geben die Patienten_Innen Schmerzen als Symptom an. Eine Verringerung der Schmerzschwere um ≥ 2 NRS Punkten, oder eine Senkung <4 auf der NRS Skala kann als adäquate Analgesie definiert werden. Ein Großteil erhält keine ausreichende Analgesie.Die Literatur beschränkt sich aufgrund des Themas auf deutsche Quellen, Stellungnahmen vom Wissenschaftlichen Dienst und Berufsverbänden, sowie weiteren namhaften Experten. Besondere Berücksichtigung findet der Kommentar des StGB von Fischer. Die Fallanalyse erfolgt in Anlehnung an die juristische Gutachtenmethodik.

Masterarbeit aus dem Jahr 2024 im Fachbereich Gesundheit - Gesundheitswesen, Note: 1,3, Fliedner Fachhochschule Düsseldorf, Sprache: Deutsch, Abstract: Bundesweit steigen die Einsätze im öffentlichen Rettungsdienst an und der Fachkräftemangel nimmt gleichzeitig zu. Vielerorts können nicht mehr alle RTW besetzt werden. Die Hinweise mehren sich, dass die Versorgung großteils nicht bedarfsgerecht erfolgt. Beim Personal entstehen Unzufriedenheit und Frustration, sowie Burnout-Tendenzen lassen sich erkennen.Mit dieser Studie soll eine Definition für Bagatelleinsätze im Kontext des Rettungsdienstes einer Großstadt erstellt werden. Die analysierten Daten sollen die rettungsdienstliche Inanspruchnahme charakterisieren und den Bedarf für weitere Versorgungsstrukturen belegen.Hierzu wird eine Mixed-Methods-Studie im „exploratory sequential Design“ durchgeführt. Es wurden drei Fokusgruppeninterviews mit Leitstellendisponent:innen, Notfallsanitäter:innen und Rettungssanitäter:innen durchgeführt. Diese Daten wurden mittels MAXQDA transkri-biert, einer inhaltlich strukturierenden Inhaltsanalyse nach Kuckartz & Rädiker unterzogen, im Anschluss codiert und zwölf Aussagen abgeleitet worden. Diese wurden im Herbst 2023 in einer 7-wöchigen retroperspektivische Querschnittsstudie beurteilt und deskriptiv ausgewertet.In den Fokusgruppeninterviews konnte eine mangelnde Gesundheitskompetenz als gesellschaftliche Veränderung identifiziert werden. Als Kriterium eines Bagatelleinsatzes konnte eine fehlende Lebensgefahr bzw. nicht absehbare Folgeschäden, eine nicht erforderliche fachliche Einschätzung durch Notfallsanitäter:innen, nicht indizierte lebensrettende Maßnahmen und die nicht notwendige Technik eines RTW als Kriterien identifiziert werden. Die Bagatelleinsatzquote entspricht somit 36,4%. Der NACA Score I und II sind in 48,3 % der RTW Einsätze belegt. Zudem sind in 4,5 % invasive Maßnahmen notwendig und in 7,4 % ein Transport mit Sonder- und Wegerechten durchgeführt worden. Indes macht die Altersgruppe über 70 Jahre 40% aller Einsätze aus.Aus der rein nichtärztlichen Sichtweise wird der Zeitpunkt des Patientenkontaktes betrachtet. Es lässt sich die Frage aufwerfen, ob dieser Ansatz und die vier Kriterien differenziert genug sind. Dennoch sind diese Eigenschaften greifbar und lassen sich per Telefon abfragen bzw. einschätzen.Eine rettungsdienstliche Versorgung durch Notfallsanitäter:innen ist selten erforderlich. Es lässt sich dadurch schlussfolgern, dass es großteils zu einer Überversorgung kommt.

During Aussois 2001, Jack con?rmed: "'Eureka - you shrink!' is really true, except that instead of 'Eureka' it maybe was some less digni?ed word." Aussois 2001 was the ?fth in an annual series of workshops on combinatorial optimization that are alternately organized by Thomas Liebling, Denis Naddef, andLaurenceWolsey-theinitiatorsofthisseries-inevenyearsandtheeditors of this book in odd years (except 1997). We decided to dedicate Aussois 2001 to Jack Edmonds in appreciation of his groundbreaking work that laid the foundations of much of what combinatorial optimizers have done in the last 35 years. Luckily, Jack is a regular participant of the Aussois workshops and, as ever, he cares a lot for young combinatorial optimizers who traditionally play a major r ole in the Aussois series. Fig.1.Handout for the Aussois 2001 participants VI Preface Highlights of Aussois 2001 included a special session entitled "Eureka - you shrink!" in honor of Jack and a special lecture by Jack on "Submodular Fu- tions, Matroids, and Certain Polyhedra" that closed the workshop. In this book, we give an account of the "Eureka - you shrink!" session as well as reprints of three hardly accessible papers that Jack gave as a handout to the Aussois 2001 participants and that were originally published in theProceedings oftheCalgaryInternationalConferenceonCombinatorialStructuresandTheir Applications 1969, Gordon and Breach (1970) - newly typeset by the editors and reprinted by permission.

Automatic Graph Drawing is concerned with the layout of relational structures as they occur in Computer Science (Data Base Design, Data Mining, Web Mining), Bioinformatics (Metabolic Networks), Businessinformatics (Organization Diagrams, Event Driven Process Chains), or the Social Sciences (Social Networks).In mathematical terms, such relational structures are modeled as graphs or more general objects such as hypergraphs, clustered graphs, or compound graphs. A variety of layout algorithms that are based on graph theoretical foundations have been developed in the last two decades and implemented in software systems.After an introduction to the subject area and a concise treatment of the technical foundations for the subsequent chapters, this book features 14 chapters on state-of-the-art graph drawing software systems, ranging from general "tool boxes'' to customized software for various applications. These chapters are written by leading experts, they follow a uniform scheme and can be read independently from each other.

Martin Grötschel is one of the most influential mathematicians of our time. He has received numerous honors and holds a number of key positions in the international mathematical community. He celebrated his 65th birthday on September 10, 2013. Martin Grötschel’s doctoral descendant tree 1983–2012, i.e., the first 30 years, features 39 children, 74 grandchildren, 24 great-grandchildren and 2 great-great-grandchildren, a total of 139 doctoral descendants.This book starts with a personal tribute to Martin Grötschel by the editors (Part I), a contribution by his very special “predecessor” Manfred Padberg on “Facets and Rank of Integer Polyhedra” (Part II), and the doctoral descendant tree 1983–2012 (Part III). The core of this book (Part IV) contains 16 contributions, each of which is coauthored by at least one doctoral descendant.The sequence of the articles starts with contributions to the theory of mathematical optimization, including polyhedral combinatorics, extended formulations, mixed-integer convex optimization, super classes of perfect graphs, efficient algorithms for subtree-telecenters, junctions in acyclic graphs and preemptive restricted strip covering, as well as efficient approximation of non-preemptive restricted strip covering.Combinations of new theoretical insights with algorithms and experiments deal with network design problems, combinatorial optimization problems with submodular objective functions and more general mixed-integer nonlinear optimization problems. Applications include VLSI layout design, systems biology, wireless network design, mean-risk optimization and gas network optimization.Computational studies include a semidefinite branch and cut approach for the max k-cut problem, mixed-integer nonlinear optimal control, and mixed-integer linear optimization for scheduling and routing of fly-in safari planes.The two closing articles are devoted to computational advances in generalmixed integer linear optimization, the first by scientists working in industry, the second by scientists working in academia.These articles reflect the “scientific facets” of Martin Grötschel who has set standards in theory, computation and applications.

This proceedings volume contains extended abstracts of talks presented at the 18th Symposium on Operations Research held at the University of Cologne, September 1-3, 1993. The Symposia on Operations Research are the annual meetings of the Gesellschaft fiir Mathematik, Okonometrie und Operations Research (GMOOR), a scientific society providing a link between research and applications in the areas of applied mathematics, economics and operations research. The broad range of interests and scientific activities covered by GMOOR and its members was demonstrated by about 250 talks presented at the 18th Symposium. As in l''ecent years, emphasis was placed on optimization and stochastics, this year with a special focus on combinatorial optimization and discrete mathematics. We appreciate that with sections on parallel and distributed computing and on scientific computing also new fields could be integrated into the scope of the GMOOR. This book contains extended abstracts of most of the papers presented at the con ference. Long versions and full papers of the talks are expected to appear elsewhere in refereed periodicals. The contributions were divided into sixteen sections: (1) Theory of Optimization, (2) Computational Methods of Optimization, (3) Combinatorial Optimization and Dis crete Mathematics, (4) Scientific Computing, (5) Decision Theory, (6) Mathematical Economics and Game Theory, (7) Banking, Finance and Insurance, (8) Econometrics, (9) Macroeconomics and Economic Theory, (10) Stochastics, (11) Production and Lo gistics, (12) System and Control Theory, (13) Routing and Scheduling, (14) Knowledge Based Systems, (15) Information Systems and (16) Parallel and Distributed Compu ting.

The Symposia on Operations Research are the annual meetings of the Gesellschaft fiir Mathematik, Okonometrie und Operations Research (GMOOR), a scientific society providing a link between research and applications in the areas of applied mathematics, economics and operations research. The broad range of interests and scientific activities covered by GMOOR and its members was demonstrated by about 250 talks presented at the 18th Symposium. As in l'ecent years, emphasis was placed on optimization and stochastics, this year with a special focus on combinatorial optimization and discrete mathematics. We appreciate that with sections on parallel and distributed computing and on scientific computing also new fields could be integrated into the scope of the GMOOR. This book contains extended abstracts of most of the papers presented at the con ference. Long versions and full papers of the talks are expected to appear elsewhere in refereed periodicals. The contributions were divided into sixteen sections: (1) Theory of Optimization, (2) Computational Methods of Optimization, (3) Combinatorial Optimization and Dis crete Mathematics, (4) Scientific Computing, (5) Decision Theory, (6) Mathematical Economics and Game Theory, (7) Banking, Finance and Insurance, (8) Econometrics, (9) Macroeconomics and Economic Theory, (10) Stochastics, (11) Production and Lo gistics, (12) System and Control Theory, (13) Routing and Scheduling, (14) Knowledge Based Systems, (15) Information Systems and (16) Parallel and Distributed Compu ting.
