The utility of three-dimensional (3D) printed models for medical education in complex congenital heart disease (CHD) is sparse and limited. The purpose of this study was to evaluate the utility of 3D printed models for medical education in criss-cross hearts covering a wide range of participants with different levels of knowledge and experience, from medical students, clinical fellows up to senior medical personnel. Study participants were enrolled from four dedicated imaging workshops developed between 2016 and 2019. The study design was a non-randomized cross-over study to evaluate 127 participants' level of understanding of the criss-cross heart anatomy. This was evaluated using the scores obtained following teaching with conventional images (echocardiography and magnetic resonance imaging) versus a 3D printed model learning approach. A significant improvement in anatomical knowledge of criss-cross heart anatomy was observed when comparing conventional imaging test scores to 3D printed model tests [76.9% (61.5%–87.8%) vs. 84.6% (76.9%–96.2%), P < 0.001]. The increase in the questionnaire marks was statistically significant across all academic groups (consultants in pediatric cardiology, fellows in pediatric cardiology, and medical students). Ninety-four percent (120) and 95.2% (121) of the participants agreed or strongly agreed, respectively, that 3D models helped them to better understand the medical images. Participants scored their overall satisfaction with the 3D printed models as 9.1 out of 10 points. In complex CHD such as criss-cross hearts, 3D printed replicas improve the understanding of cardiovascular anatomy. They enhanced the teaching experience especially when approaching medical students.  相似文献

Supporting preschoolers’ cognitive development: Short- and mid-term effects of fluid reasoning,visuospatial, and motor training     

Valentina Gizzonio  Maria Chiara Bazzini  Cosima Marsella  Pamela Papangelo  Giacomo Rizzolatti  Maddalena Fabbri-Destro 《Child development》2022,93(1):134-149

Cognitive abilities are essential to children's overall growth; thus, the implementation of early and effective training interventions is a major challenge for developmental psychologists and teachers. This study explores whether an intervention simultaneously operating on fluid reasoning (FR), visuospatial, narrative, and motor abilities could boost these competencies in a group of Italian preschoolers (N = 108, 54 males 54 females, Age_mean = 4.04). FR and visuospatial abilities showed training-related increases at the end of the training and 1-year follow-up (moderate effect size). Interestingly, positive correlations with working memory and mathematical abilities were found. Beyond their scientific relevance, the short- and long-term effects provide fundamental indications for designing and implementing educational programs dedicated to preschoolers.  相似文献   

Autonomic modulation of heart rate in paraplegic wheelchair basketball players: Linear and nonlinear analysis     

Antonio Roberto Zamunér  Ester Silva  Rosana Macher Teodori  Aparecida Maria Catai  Marlene Aparecida Moreno 《Journal of sports sciences》2013,31(4):396-404

Abstract

This study aimed to evaluate the autonomic modulation of heart rate in sedentary paraplegics and paraplegic wheelchair basketball players with thoracic spinal cord injury below T6. Seven paraplegic wheelchair basketball players (active paraplegic group), five paraplegics who were not involved in regular exercise (sedentary paraplegic group) and 10 able-bodied participants (control group) took part in the study. The heart rate variability was evaluated by linear (low frequency and high frequency band in normalised units and low frequency/high frequency ratio) and nonlinear methods (Shannon entropy, corrected conditional entropy, and symbolic analysis).

The sedentary group presented significantly higher values for low frequency, low frequency/high frequency ratio and symbolic index with no significant variations (0V%), and also lower values for the high frequency and symbolic index with two significant unlike variation (2ULV%) compared to active paraplegic group. Shannon entropy and corrected conditional entropy analyses revealed significantly lower values in the sedentary group than in the control or active paraplegic groups. Paraplegic individuals who regularly undertake physical exercise have higher complexity of R-R interval time series, lower sympathetic modulation, and higher parasympathetic modulation than sedentary paraplegic participants.  相似文献   

Tannins characterization in historic leathers by complementary analytical techniques ATR-FTIR,UV-Vis and chemical tests     

Lina Falcão  Maria Eduarda M. Araújo 《Journal of Cultural Heritage》2013,14(6):499-508

This paper presents a complementary analytical approach to characterize vegetable tanning materials in historic leathers. It is described the application of two molecular spectroscopic techniques, ATR-FTIR and UV-Vis, and three specific chemical tests to analyse tannins present in leathers. Acid butanol, nitrous acid and rhodanine colorimetric tests, evaluated both visually and spectrophotometrically, were used to identify condensed tannins, ellagitannins and gallotannins, respectively. Ten samples of commercial, or laboratory prepared, vegetable tannins and seven new vegetable tanned leathers were also analysed and obtained results were used for comparison. The complete analytical procedure was performed, in a semi-micro-destructive scale, using fibres collected from leather. Analysis of ATR-FTIR and UV spectra of commercial and laboratory prepared vegetable tannins allowed the establishment of the characteristic bands of condensed and hydrolysable tannins and, more specifically, gallotannins. These data were used to confirm the type of vegetable tanning agents used in new leather extracts. The same approach was used in cultural heritage leathers, supported by the colorimetric tests, since protein degradation products were co-extracted in aged leathers and interfered in IR spectra.  相似文献   

Basic values predict doping likelihood     

Christopher Ring  Maria Kavussanu  Bahri Gürpınar 《Journal of sports sciences》2020,38(4):357-365

ABSTRACT

Basic values, defined as trans-situational goals that vary in importance and act as guiding principles in life, have been linked with unethical cognitions, emotions and actions. Their roles in doping, a form of cheating in sport, have yet to established. College athletes reported doping likelihood in hypothetical scenario-based situations and completed measures of basic values, moral disengagement, and anticipated guilt. Correlation analysis showed that doping likelihood was positively associated with self-enhancement values but negatively associated with self-transcendence values and conservation values. Moral disengagement correlated positively with self-enhancement values and negatively with self-transcendence values, whereas guilt correlated positively conservation values and negatively with self-enhancement values and openness to change values. Regression analyses showed that self-enhancement values positively predicted doping likelihood directly, self-transcendence values negatively predicted doping likelihood indirectly via moral disengagement and guilt, and conservation values negatively predicted doping likelihood indirectly via guilt. In line with theory and evidence concerning the relationship between basic value systems and moral thought and action, we found that the values of athletes are directly (self-enhancement) and indirectly (self-transcendence, conservation) linked with likely use of banned performance enhancing substances, an expression of cheating in sport.  相似文献   

The audiovisual action plan: a new audiovisual policy for Ireland     

Maria O’Brien 《Cultural Trends》2019,28(5):417-428

ABSTRACT

This article analyses the recent plan for the audiovisual industries introduced (after some delay) by the Irish Department of Culture, Heritage and the Gaeltacht. The Audiovisual Action Plan (“the Plan”) sets out the Department’s approach to the audiovisual industries and is, it is contended, evidence of a marketization of culture consistent with a creative industries perspective. The analysis of the Plan in a wider policy context identifies key issues shaping audiovisual production in Ireland. Using a thematic analysis approach from Braun and Clark (2005, 2019) a number of themes are developed from analysis of the relevant policy documents, broadly conceived around the increasing instrumentalism of culture. Taking a political economy perspective allows for development of themes around the commodification of the nation-state through the provision of policies that actively encourage a certain type of audiovisual production. Building on Mosco’s work on political economy (Mosco, 2009) the concept of spatialization from Lefebvre (Lefebvre, 1991) is used to interrogate the production of and commodification of space through Specifically, this article interrogates the policy norms underpinning the Audiovisual Action Plan introduced by the Department of Culture, Heritage and the Gaeltacht in Ireland in 2018 as part of Culture 2025, the national cultural policy framework. It identifies the key proposals which affect the audiovisual industries. It is concluded that the Plan (and other relevant policy documents) support a spatialized, commodified view of the audiovisual industries as primarily industrial in nature, paying scant attention to the consideration of such industries as cultural forces.  相似文献

A sport for all programme in school: girls’ experiences     

Peter Carlman  Maria Hjalmarsson 《Sport in Society》2019,22(3):416-431

This article examines a Swedish Sport for All Programme (SAP) in school. We use a case study to discuss girls’ debut in alternative sports programme organized in collaboration between school and the sports movement. The empirical data are derived from repeated focus group interviews with one group of seven 10-year-old girls participating in one SAP. The analyses focus on their subjective experiences and how broader gender structures influence these experiences. Drawing on the results of this study, we argue that certain sports can be interpreted as oppressive activities that produce asymmetric power relationships between different groups of children. Simultaneously, the girls see the idea of sports as joyful activities, without male abuse and oppression or hierarchical gender relationships. Based on the girls’ accounts, we claim that both the leaders and the children actively reproduce gender stereotypes in the SAP.  相似文献
