In order to improve learning efficiency and memory retention in medical teaching, furthering active learning seems to be an effective alternative to classical teaching. One option to make active exploration of the subject matter possible is the use of virtual reality (VR) technology. The authors developed an immersive anatomy atlas which allows users to explore human anatomical structures interactively through virtual dissection. Thirty-two senior-class students from two German high schools with no prior formal medical training were separated into two groups and tasked with answering an anatomical questionnaire. One group used traditional anatomical textbooks and the other used the immersive virtual reality atlas. The time needed to answer the questions was measured. Several weeks later, the participants answered a similar questionnaire with different anatomical questions in order to test memory retention. The VR group took significantly less time to answer the questionnaire, and participants from the VR group had significantly better results over both tests. Based on the results of this study, VR learning seems to be more efficient and to have better long-term effects for the study of anatomy. The reason for that could lie in the VR environment's high immersion, and the possibility to freely and interactively explore a realistic representation of human anatomy. Immersive VR technology offers many possibilities for medical teaching and training, especially as a support for cadaver dissection courses. 相似文献

In the industrialized world the probability of people reaching higher ages has risen substantially over the past decade. Falling birth and mortality rates have led to changes in the population structure. In Germany, the population will be aging rapidly over the next (decades), with the new demographic situation necessitating adjustment and re-orientation on the individual and socio-political level. We argue that the adjustment strategies should focus on the promotion of education across all phases of life and population groups. This applies to the issue of health, for example, since future strains on the social welfare system and macroeconomic performance are affected, among other factors, by the state of health of the growing number of elderly people. Education boosts health-promoting behavior, thus increasing the chances of an individual enjoying a long, active life. Besides, educational training and professional development are gaining importance owing to demographic change as the changes in the population structure will require individuals to work longer over their working lives and lead to a more even distribution of gainful employment across the life course. Education is a worthwhile investment, in particular as the prospects for long life are rising and because it enables people to lead their lives as responsible agents, to take charge of their personal individual and professional development, and to assure their livelihood. 相似文献

The jump throw is one of the most applied techniques in handball. Therefore, analyzing its underlying performance factors is important since they may provide a basis to adjust training interventions. Currently, the coach decides what needs to be improved in order to enhance the overall performance of an athlete. The aim of this study is to break down the performance factors in jump throws and to assign athletes to subgroups. This classification should allow athletes to benefit from the resulting group-specific training contents and may support a coach in deciding about the next steps in his training program. A total of 113 male handball players (age 15 ± 0.38 years, height 184.07 ± 7.1?cm, weight 74.83 ± 9.31?kg) participated in this study. From each athlete the standing reach height (SRH), the jumping reach height achieved with a countermovement jump (JRH), the maximal ball height achieved with a handball-specific single-legged jump and straight arm (BHJ), and the ball release height achieved in a jump throw (BHT) were measured. Performance factors were derived as differences between these measurements (JRH ? SRH = UJA for unspecific jump ability, BHJ ? JRH = SJT for specific jump technique, BHT ? BHJ = STT for specific throwing technique). A hierarchical cluster analysis was used to find groups of athletes based on the derived and scaled difference measures (UJA, SJT, STT). The dendrogram shows a clear distinction of four groups of athletes. Average values within each cluster reveal (A) one group with high UJA values, (B) one with low UJA values, (C) one with high SJT but low STT, and (D) one with low SJT but high STT. These results may be interpreted with respect to consequences for training because group (B) seems to benefit most from a general strength training while the properties of group (A), (C), and (D) recommend a focus on technical aspects of performance. 相似文献

Für ein vollst?ndig computergestütztes Planungssystem zum Zwecke der kieferchirurgischen Operationsplanung ist die Bereitstellung von virtuellen Werkzeugen für den Chirurgen eine grundlegende Voraussetzung. Ausgehend von den Volumendaten mit Sch?del- und Kieferknochen des Patienten erm?glicht ein einfaches Interface unter Verwendung einer geeigneten Visualisierung und haptischer Eingabeger?te die interaktive Definition und Manipulation einzelner virtueller Knochensegmente. Wir haben moderne kraftrückgekoppelte Ger?te aus dem Niedrigpreisbereich eingebunden und auf ihre F?higkeit untersucht, das dreidimensionale Verst?ndnis im Planungsproze?durch Anlehnung an die Vorg?nge bei der chirurgischen Prozedur zu erh?hen. Durch diese Eingabeger?te ist es m?glich, die Knochensegmentierung für eine Osteotomie des Unterkiefers intuitiver und schneller durchzuführen. Die definierten Teilvolumina ergeben zusammen mit ihrer r?umlichen Neuanordnung auf Grundlage einer kephalometrischen Analyse einen Operationsplan. Nach erfolgter Planung werden die Planungsergebnisse in den Operationssaal übertragen. Die intraoperativen Techniken beinhalten die Visualisierung der Planungsergebnisse, die Steuerung der Anwendung über Sprache und die Bestimmung der Patientenposition mittels eines elektromagnetischen 3D-Trackingsystems. 相似文献

In this study, 123 children with a diagnosis of developmental dyslexia were assigned to different treatment groups, either variations of Bakker's intervention program based on the balance model or a control, a specific reading training group. Thorough cognitive and neuropsychological assessment allowed determination of the subtype of dyslexia according to the balance model and the neuropsychological profile with respect to reading and spelling abilities, verbal memory, and phonemic awareness. Characteristics of hemisphere-specific stimulation were systematically manipulated in an effort to shed light on the bases and mechanisms of reading improvement. It was shown that the effects of treatment vary according to type of dyslexia and that the different intervention programs have differential effects on reading-related neuropsychological functions. Since opposite effects can be produced by the same type of treatment in different dyslexia subtypes, the results of the study suggest that accurate classification of subtype on the base of reading and reading-related variables is advantageous for an optimal planning of the therapy. 相似文献

Die Entwicklung eingebetteter Software für Automobile ist inh?rent komplex und vereint verschiedene
Entwicklungsphasen, mehrere fachliche Disziplinen, sowie verschiedene Akteure in beteiligten Unternehmen.
Der AutoMoDe-Ansatz zur Entwicklung automotiver Software beschreibt Systeme auf verschiedenen Abstraktionsebenen
und definiert schrittweise überg?nge zwischen diesen Ebenen. Neben der Definition geeigneter
Ebenen werden zur Modellierung von Echtzeitsystemen ein einheitliches Berechnungsmodell sowie dom?nenspezifische
Beschreibungstechniken verwendet. Automatisierte Anbindungen für Analyse und Synthese komplexer Softwaresysteme
mit dem Ziel eines konsistenzbetonten Entwicklungsprozesses wurden realisiert. Die beschriebenen Techniken
wurden in den Werkzeugprototypen AutoFocus integriert und im Zusammenspiel
mit einer Werkzeugkette demonstriert. 相似文献

Our research aims to identify domain-specific similarities and differences of externalized cognitive structures. Cognitive structure, also known as knowledge structure or structural knowledge, is conceived as the manner in which an individual organizes the relationships of concepts in memory. By diagnosing these structures precisely, even partially, the educator comes closer to influencing them through instructional settings and materials. Our assessment and analysis of cognitive structures is realized within the HIMATT tool, which automatically generates four quantitative indicators for the structural entities of written text or causal maps. In our study, participants worked on the subject domains biology, history, and mathematics. Results clearly indicate different structural and semantic features across the three subject domains. Additionally, we found that written texts and causal maps seem to represent different structure and content across the three subject domains when compared to an expert??s representation. We conclude with a general discussion, instructional implications and suggestions for future research. 相似文献
