Neste artigo, pretende-se apontar para uma tensão dialética entre o racional e o irracional, entre o conceito e o não conceitual, atualizando o sentido do não idêntico. Essa atualização configura-se na necessidade de potencializar uma filosofia da educação crítico-formativa com base na perspectivada “expressividade estética”. A questão que se coloca é a seguinte: como podemos compreender o sentido do não idêntico, a partir das necessidades de uma educação crítico-formativa e das condições para efetivá-la no âmbito das reflexões filosófico-educacionais? Desse modo, faz-se uma breve incursão no que consiste o papel da dialética negativa do filósofo Theodor W. Adorno para se pensar o sentido da “razão” (ou das razões) na perspectiva do “não idêntico”. Partindo disso, busca--se apontar as possibilidades da crítica imanente adorniana, cujo escopo manifesta na dialética do sofrimento no âmbito do capitalismo. Por fim, pretende-se assinalar e discutir a potencialidade da “expressividade estética” do não idêntico, articulada com algumas possibilidades para a educação no contexto atual.
Congenitally blind individuals have been shown to activate the visual cortex during non-visual tasks. The neuronal mechanisms of such cross-modal activation are not fully understood. Here, we used an auditory working memory training paradigm in congenitally blind and in sighted adults. We hypothesized that the visual cortex gets integrated into auditory working memory networks, after these networks have been challenged by training. The spectral profile of functional networks was investigated which mediate cross-modal reorganization following visual deprivation. A training induced integration of visual cortex into task-related networks in congenitally blind individuals was expected to result in changes in long-range functional connectivity in the theta-, beta- and gamma band (imaginary coherency) between visual cortex and working memory networks. Magnetoencephalographic data were recorded in congenitally blind and sighted individuals during resting state as well as during a voice-based working memory task; the task was performed before and after working memory training with either auditory or tactile stimuli, or a control condition. Auditory working memory training strengthened theta-band (2.5-5 Hz) connectivity in the sighted and beta-band (17.5-22.5 Hz) connectivity in the blind. In sighted participants, theta-band connectivity increased between brain areas typically involved in auditory working memory (inferior frontal, superior temporal, insular cortex). In blind participants, beta-band networks largely emerged during the training, and connectivity increased between brain areas involved in auditory working memory and as predicted, the visual cortex. Our findings highlight long-range connectivity as a key mechanism of functional reorganization following congenital blindness, and provide new insights into the spectral characteristics of functional network connectivity.
Introduction: Microsurgery courses, taught external to surgical training programs, are essential for acquiring the high level of technical skill required for clinical proficiency.
Methods: The Frankfurt microsurgery course is a 5-day, intensive course that teaches arterial and venous anastomosis using end-to-end, end-to-side, one-way-up, continuous-suture, and vessel graft techniques. During the course, the instructor records the level of skill (in-course data) achieved by each trainee by assessing anastomosis completion and patency. Demographic information is also collected. Post-course trainees are invited to complete an online survey (post-course data) to get their opinions of the courses’ effectiveness.
Results: The in-course “skill achievement” and post-course “course effectiveness” data are presented below. In-course data: 94.8 and 59.9% of participants completed patent end-to-end arterial and venous anastomoses, respectively, while 85.4% performed a patent end-to-side anastomosis. 96.1 and 57.1% of participants who attempted arterial and venous anastomoses using the one-way-up technique were successful, as were 90.9% of those attempting continuous-suture technique. Patent venous grafts were performed by 54.7% of participants.
Post-course data: All respondents indicated significant improvement of their microsurgical skills after taking the course. 66.7% of respondents considered the full-time presence of the instructor to be the most valuable aspect of the course. All respondents would highly recommend the course to colleagues.
Conclusion: The microcourse significantly increased trainees’ clinical microsurgery skills, confidence, and the number of clinical cases they perform. Of all the anastomosis techniques taught, venous anastomosis and grafting were the most difficult to learn. The presence of a full-time experienced instructor was most important.
Aims: Understanding the orientation of fracture lines and mechanisms is the essential key to sufficient surgical therapy, but there is still a lack of visualization and teaching methods in traumatology and fracture theory. 3D-printed models offer easy approach to those fractures. This paper explains the use of the teaching possibility with 3-dimensional models of transitional fractures of the ankle.
Methods and results: For generating 3D printable models, already obtained CT data were used and segmented into its different tissues, especially parts concerning the fracture. After the segmentation process, the models were produced with FFF (fused filament fabrication) printing technology. The fracture models then were used for hands-on teaching courses in AO course (Arbeitsgemeinschaft für Osteosynthesefragen) of pediatric traumatology in 2020 in Frankfurt. In the course fracture anatomy with typical fracture lines, approaches, and screw placement could be shown, discussed and practiced.
Conclusion: The study shows the use of 3D-printed teaching models and helps to understand complicated fractures, in this case, transitional fractures of the ankle. The teaching method can be adapted to numerous other use cases.
Interest to become a data scientist or related professions in data science domain is rapidly growing. To meet such a demand, we propose a novel educational service that aims to provide tailored learning paths for data science. Our target user is one who aims to be an expert in data science. Our approach is to analyze the background of the practitioner and match the learning units. A critical feature is that we use gamification to reinforce the practitioner engagement. We believe that our work provides a practical guideline for those who want to learn data science.
Background/Objectives: Agility and cognitive abilities are typically assessed separately by different motor and cognitive tests. While many agility tests lack a reactive decision-making component, cognitive assessments are still mainly based on computer-based or paper-pencil tests with low ecological validity. This study is the first to validate the novel SKILLCOURT technology as an integrated assessment tool for agility and cognitive-motor performance.
Methods: Thirty-two healthy adults performed agility (Star Run), reactive agility (Random Star Run) and cognitive-motor (executive function test, 1-back decision making) performance assessments on the SKILLCOURT. Cognitive-motor tests included lower limb responses in a standing position to increase the ecological validity when compared to computer-based tests. Test results were compared to established motor and agility tests (countermovement jump, 10 m linear sprint, T-agility tests) as well as computer-based cognitive assessments (choice-reaction, Go-NoGo, task switching, memory span). Correlation and multiple regression analyses quantified the relation between SKILLCOURT performance and motor and cognitive outcomes.
Results: Star Run and Random Star Run tests were best predicted by linear sprint (r = 0.68, p < 0.001) and T-agility performance (r = 0.77, p < 0.001), respectively. The executive function test performance was well explained by computer-based assessments on choice reaction speed and cognitive flexibility (r = 0.64, p < 0.001). The 1-back test on the SKILLCOURT revealed moderate but significant correlations with the computer-based assessments (r = 0.47, p = 0.007).
Conclusion: The results support the validity of the SKILLCOURT technology for agility and cognitive assessments in more ecologically valid cognitive-motor tasks. This technology provides a promising alternative to existing performance assessment tools.
Ziel des Seminars war, sportmedizinische und präventivmedizinische Aspekte zu Fitness und Wellness zu präsentieren und hierbei insbesondere auf die historische Entwicklung der Sportmedizin einzugehen sowie Techniken und Wirkungen verschiedener Massageformen und ganzheitliche asiatische Gesundheitsansätze und Bewegungskünste zu erörtern.
Im ersten Teil der Publikation werden die Bedeutung von Bewegung und Prävention sowie präventionsbezogene Begriffe erläutert.
Im nächsten Abschnitt werden die Auswirkungen von Bewegungsmangel und von körperlicher Aktivität auf verschiedene Organsysteme dargelegt.
Es folgen die hieraus zu ziehenden Konsequenzen für ein präventiv nutzbares Training. Es werden dabei auch zur Motivierung Sporttreibender einsetzbare Faustregeln zur Leistungsfähigkeit und zur Trainierbarkeit (maximale Sauerstoffaufnahme, maximale ergometrische Leistungsfähigkeit und deren Veränderungen mit dem Alter und ihre Trainierbarkeit) erläutert.
Einleitung Welche Methoden der Leistungssteigerung gibt es eigentlich im Sport? Von körperlicher Aktivität und Training (mit einer Fülle positiver Wirkungen) über Ernährung und Nahrungsergänzungsmittel bis zu unerlaubten Mitteln. Welche Methoden wirken? Was ist sinnvoll? Was ist erlaubt? Was ist überflüssig? Wo kann der einzelne mit seinen eigenen Erwartungshaltungen dazu beitragen, zum Beispiel unrealistischen Leistungsdruck gegenüber Sporttreibenden und damit eine potentielle Dopingproblematik im Ursprung zu vermeiden? Diese Fragen wollte die Veranstaltung „Leistungssteigerung im Sport - Ursachen, Methoden, Bewertungen, Lösungen“ des Arbeitskreises Sportmedizin der Akademie für ärztliche Fortbildung und Weiterbildung der Landesärztekammer Hessen (Prof. Dr. med.
