Despite the importance of body donation for medical education and the advancement of medical science, cadaveric donation remains suboptimal worldwide. The purpose of this study was to evaluate the willingness of body donation in Greece and determine the characteristics of donors. This cross‐sectional questionnaire survey was conducted from January to June 2011. A specially designed questionnaire was distributed to 1,700 individuals who were randomly selected from five major Greek cities. It was found that higher educational levels (P = 0.002), annual family income below 30,000 Euros (P = 0.001), guaranteed employment status (P = 0.02), and the presence of comorbid conditions (P = 0.004) seemed to affect potential donors' willingness for cadaveric donation. Those with strong religious beliefs were found to be unwilling to donate their bodies to medical science. Interestingly, the majority of participants who believed that hospitalized patients are deceived or are used for harmful experiments were willing to become whole body donors (P = 0.043). In Greece, the rate of body donation to medical science remains low, and most Greek citizens are not willing to become body donors. Efforts to encourage discussions about whole body donation should be implemented in order to improve current low levels of donation. Anat Sci Educ. © 2012 American Association of Anatomists.  相似文献

This study compared knee angle-specific neuromuscular adaptations after two low-volume isometric leg press complex training programmes performed at different muscle lengths. Fifteen young males were divided into two groups and trained three times per week for 6 weeks. One group (n?=?8) performed 5–7 sets of 3 s maximum isometric leg press exercise, with 4?min recovery, with knee angle at 85°?±?2° (longer muscle-tendon unit length; L-MTU). The other group (n?=?7) performed the same isometric training at a knee angle of 145°?±?2° (180°?=?full extension; shorter muscle-tendon unit length; S-MTU). During the recovery after each set of isometric exercise, participants performed two CMJ every minute, as a form of complex training. Maximum isometric force (MIF) and rate of force development (RFD) were measured over a wide range of knee angles. Countermovement jump (CMJ) performance and maximum half-squat strength (1RM) were also assessed. Training at S-MTU induced a large increase of MIF (22–58%, p?p?p?=?0.001). In contrast, training at L-MTU, resulted in a moderate and similar (≈12.3%, p?=?0.028) improvement of force at all knee angles. CMJ performance and 1RM were equally increased in both groups after training by 10.4%?±?8.3% and 7.8%?±?4.7% (p?相似文献

The study assessed cognitive and academic performance of children demonstrating teacher-rated ADHD-related symptoms (Inattention [IA] and/or Hyperactivity/Impulsivity [H/I]) in a representative sample of, largely untreated, Greek elementary school students (N?=?923). A battery of tests assessing short-term memory (STM), sustained attention, executive functions (EFs), reading and math skills were administered. Significant deficits in EFs and STM were restricted to the groups of students displaying inattention symptoms and were only marginally elevated among students showing hyperactivity/impulsivity symptoms alone, in comparison to their non-symptomatic peers. A similar pattern of group differences was observed on tests assessing word- and text-level reading skills. Impaired performance on sustained attention tasks was less evident. Among students who manifested inattention symptoms, those who also showed impaired reading skills presented more severe EFs deficits than typically achieving students. Results demonstrated a close link between EFs, other than inhibition and set-shifting, everyday symptoms of inattention, and achievement in math and word-level reading skills.  相似文献

The students of a Greek junior high school collaborated to prepare the teaching material of a theoretical Computer Science (CS) course and then shared their understanding with other students. This study investigates two alternative teaching methods (collaborative learning and peer tutoring) and compares the learning results to the traditional learning context. A test was used to measure all participating students’ learning results and a questionnaire was distributed to record participant student attitudes towards the alternative teaching conditions. The questionnaire was designed to evaluate each aspect in terms of perceived knowledge, experience, satisfaction, diversity, oddness and interest. The analysis explores potential differences of students’ learning results between alternative and traditional teaching and also differences in the two aspects in relation to students’ preferences. Results provide evidence that active-learning methods can promote positive attitudinal shifts and improve skills in creativity, teamwork, collaboration and communication. Students perceived higher levels of learning than with traditional teaching. Finally in terms of students’ preferences, the majority wanted to have more courses taught with active-learning methods.  相似文献

In this research we investigate whether the categorisation of physical quantities into intensive and extensive, according to scientific knowledge, is perceivable and understood by pupils aged 12–15 years. For this purpose we administered written questionnaires to 300 pupils, comprising four tasks for each intensive quantity: density and pressure. The tasks investigate whether pupils realise that intensive quantities do not depend on the amount of the system they refer to and the factors affecting pupils' reasoning and their consistency when studying phenomena involving fluids at rest or in transition. The analysis of responses led us to identify three models of consistent pupils' reasoning. It was also observed that a significant percentage of the pupils provide inconsistent answers, that is, they change their reasoning across tasks and use alternatives to scientific reasoning, influenced by phenomenological features of the tasks. According to our results we propose a number of recommendations, such as the introduction of intermediate teaching/learning steps to be followed as well as suitable experiments to be used towards the acquisition of the scientific model for density and pressure.  相似文献

This is a study of the structure of ‘The Blegdamsvej Faust’ and its relation to Goethe's classical play Faust. The ‘Blegdamsvej Faust’, a play written and performed by Bohr's students in 1932, is inspired by the very rapid development of Physics in those turbulent years. A struggle is made to promote the odd idea of a weightless particle. Moreover, this study lays emphasis on the fact that new ideas of Physical Sciences become more accessible, comprehensible and familiar through dramatization. For scenario-vehicles one may use as a basis plays from the classical repertoire or write something new. Several hints are given in this article.  相似文献

This paper describes a methodology for the development of a proactive balanced scorecard (PBSCM). The balanced scorecard is one of the most popular approaches developed in the field of performance measurement. However, in spite of its reputation, there are issues that require further research. The present research addresses the problems of the balanced scorecard by utilizing the soft computing characteristics of fuzzy cognitive maps (FCMs). By using FCMs, the proposed methodology generates a dynamic network of interconnected key performance indicators (KPIs), simulates each KPI with imprecise relationships and quantifies the impact of each KPI to other KPIs in order to adjust targets of performance.  相似文献

The year 1948, as a starting point both of this study and of the organised military sport for Greece, was particularly hectic, since the newly liberated country was embroiled in the Civil War while, simultaneously, it was trying to reconstitute itself. The next two decades were marked by the foundation and the activities of the Higher Coordinating Committee for Sport in the Armed Forces (Anotera Syntonistiki Epitropi Athlitismou Enoplon Dynameon – A.S.E.A.E.D.). This Committee organised and materialised the first steps of the newly established organised sports activities of the Hellenic Armed Forces and evolved as a result, into the Supreme Council for Sport in the Armed Forces (Anotato Symvoulio Athlitismou Enoplon Dynameon) in year 1968. Due to the lack of specific and thorough research on the topic during this era, the purpose of this study was to identify references and the original sources (archives both of the A.S.E.A.E.D. and of the Hellenic National Defense General Staff) and to highlight and reveal the activities of organised Greek military sport, in the organisational field, and the Hellenic Armed Forces' participation in international sports tournaments.  相似文献

The present study should be thought as a socioconstructivist teaching approach (a teaching model) for the concept of energy in primary education. It contains important and crucial aspects of the History and Philosophy of Natural Sciences, introduces the concept of energy using the macroscopic framework of thermodynamics, takes into consideration learners’ alternative ideas or frameworks relating to energy, takes advantage of the causal and the unifying characters of energy, which have been founded on the historiographical analysis of this concept, uses energy chains as visual representations for the deep understanding of it, uses visual grammar of Kress and van Leeuwen to design energy chains and introduces a teaching methodology for this concept.  相似文献
