Acetabular fractures are a real challenge for junior doctors as well as experienced orthopedic surgeons. Correct fracture classification is crucial for appreciating the fracture type, surgical planning, and predicting prognosis. Although three-dimensional (3D) tutorial is believed to improve the understanding of the complex anatomy structure, there have been few applications and randomized controlled trials to confirm it in orthopedics. This study aims to develop a 3D interactive software system for teaching acetabular fracture classification and evaluate its efficacy. Participants were randomly but evenly allocated into either the experimental group (who learned the acetabular fracture classification using a 3D software) or the control group (who used a traditional two-dimensional [2D] tutorial). Both groups were then tasked to classify 10 acetabular fractures and complete a five-point Likert scale on their satisfaction of each learning modality. To calculate significance (P < 0.05), independent t-test was used for normally distributed data whereas Mann-Whitney U test for non-normally distributed data. The experimental group significantly outperformed the control group (t (28) = 2.526, P = 0.017) with identifying correct acetabular fracture classification. Moreover, Likert scale score in the experimental group was also significantly higher than in the control group (Z = 2.477, P = 0.013). This 3D classification software has objectively and subjectively showed an advantage over the traditional 2D tutorial, resulting in an improved classification accuracy and higher Likert scale score. The 3D software has the potential to improve both clinical knowledge as well as identifying correct patient management in orthopedics. 相似文献

A rational approach for developing effective filaricides awaits greater knowledge on the biochemical pathways operating in filarial parasites. For example, metabolic pathways or key enzymes that are so pivotal to the parasite that their interruption or inhibition causes spontaneous death, could be exploited to develop effective chemotherapeutic agents. Similarly, developing a safe and nontoxic filaricidal will require precise understanding of whether or not the potential molecular target in the parasite is unique or at least different enough from the host system. Recently, we identified a novel transglutaminase enzyme (EC2.3.2.13; TGase) in filarial parasites that plays an important role during their normal growth and development. Based on these principles, TGase may serve as a new target for the development of effective chemotherapeutic agent and vaccine for controlling and preventing the infections caused by these parasites. 相似文献

ABSTRACT The idea of learning rooted in behavioural psychology has become dominant in the field of teaching and learning for several decades. Even though it has been widely used in formal education it is inadequate for informing lifelong learning policies and plans. In this paper, first I critique the psychological foundation of learning and in the second part, drawing on Habermasian conceptualisation of three structural components of the lifeworld (culture, society, and personality), I conceptualise the three components as the social foundations of learning: learning as cultural reproduction, learning as social integration and learning as socialisation. In the context of the UN’s declaration of ‘lifelong learning’ as one of the Sustainable Development Goals, this paper will be useful for developing policies to address challenges faced by individual countries at cultural, societal and individual levels. 相似文献

Anatomy has historically been a cornerstone in medical education regardless of nation or specialty. Until recently, dissection and didactic lectures were its sole pedagogy. Teaching methodology has been revolutionized with more reliance on models, imaging, simulation, and the Internet to further consolidate and enhance the learning experience. Moreover, modern medical curricula are giving less importance to anatomy education and to the acknowledged value of dissection. Universities have even abandoned dissection completely in favor of user‐friendly multimedia, alternative teaching approaches, and newly defined priorities in clinical practice. Anatomy curriculum is undergoing international reformation but the current framework lacks uniformity among institutions. Optimal learning content can be categorized into the following modalities: (1) dissection/prosection, (2) interactive multimedia, (3) procedural anatomy, (4) surface and clinical anatomy, and (5) imaging. The importance of multimodal teaching, with examples suggested in this article, has been widely recognized and assessed. Nevertheless, there are still ongoing limitations in anatomy teaching. Substantial problems consist of diminished allotted dissection time and the number of qualified anatomy instructors, which will eventually deteriorate the quality of education. Alternative resources and strategies are discussed in an attempt to tackle these genuine concerns. The challenges are to reinstate more effective teaching and learning tools while maintaining the beneficial values of orthodox dissection. The UK has a reputable medical education but its quality could be improved by observing international frameworks. The heavy penalty of not concentrating on sufficient anatomy education will inevitably lead to incompetent anatomists and healthcare professionals, leaving patients to face dire repercussions.

This study was conducted to find out the level of oxidative stress and effect of supplementation of vitamin C, D and Calcium
on levels of SOD, serum and urinary fluoride in children residing in endemic fluorosis area. For this the fluoride belt of
Jaipur district was selected. The parameters selected were Super oxide dismutase, serum fluoride and urinary fluoride. The
study was conducted on one hundred children, selected from four areas (25 from each area) consuming water containing 1.2,
2.4, 5.6 and 13.6 mg/l of fluoride. Drinking water fluoride, serum and urinary fluoride were measured by Ion selective electrode
method. Serum SOD by Xanthine oxidase method using kit of Ransod (kit cat. No. SD125). The post treatment values showed a
significant reduction in serum fluoride and SOD. Urinary fluoride levels increased significantly in post treatment stage.
The results revealed a normal SOD levels in all groups but an increasing trend was observed with increasing fluoride concentration.
Treatment with Calcium, Vitamin D and Vitamin C showed a significant reduction in serum fluoride and SOD and increase in urinary
fluoride. A high positive correlation between pretreatment and post treatment group was observed in serum fluoride, SOD and
urinary fluoride (P < 0.05). The study indicated an increasing oxidative stress in cases of fluorosis with increasing drinking
water fluoride concentration. Treatment with Calcium, Vitamin D and Vitamin C resulted a significant reduction in serum fluoride
and SOD and increase in urinary fluoride. 相似文献

Liquid filling in microfluidic channels is a complex process that depends on a variety of geometric, operating, and material parameters such as microchannel geometry, flow velocity∕pressure, liquid surface tension, and contact angle of channel surface. Accurate analysis of the filling process can provide key insights into the filling time, air bubble trapping, and dead zone formation, and help evaluate trade-offs among the various design parameters and lead to optimal chip design. However, efficient modeling of liquid filling in complex microfluidic networks continues to be a significant challenge. High-fidelity computational methods, such as the volume of fluid method, are prohibitively expensive from a computational standpoint. Analytical models, on the other hand, are primarily applicable to idealized geometries and, hence, are unable to accurately capture chip level behavior of complex microfluidic systems. This paper presents a parametrized dynamic model for the system-level analysis of liquid filling in three-dimensional (3D) microfluidic networks. In our approach, a complex microfluidic network is deconstructed into a set of commonly used components, such as reservoirs, microchannels, and junctions. The components are then assembled according to their spatial layout and operating rationale to achieve a rapid system-level model. A dynamic model based on the transient momentum equation is developed to track the liquid front in the microchannels. The principle of mass conservation at the junction is used to link the fluidic parameters in the microchannels emanating from the junction. Assembly of these component models yields a set of differential and algebraic equations, which upon integration provides temporal information of the liquid filling process, particularly liquid front propagation (i.e., the arrival time). The models are used to simulate the transient liquid filling process in a variety of microfluidic constructs and in a multiplexer, representing a complex microfluidic network. The accuracy (relative error less than 7%) and orders-of-magnitude speedup (30 000X–4 000 000X) of our system-level models are verified by comparison against 3D high-fidelity numerical studies. Our findings clearly establish the utility of our models and simulation methodology for fast, reliable analysis of liquid filling to guide the design optimization of complex microfluidic networks. 相似文献

In this article the author addresses the origins of trigonometry and the idea of limits. The concept of ‘limit’ is crucial in the development of integral calculus, the subject which deals with the measurements of lengths, areas and volumes of general figures. What emerges is that the roots of trigonometry and integral calculus are already implicit in the early geometrical studies. 相似文献

In the first three parts the author covered what can roughly be called ‘classical’ geometry. These are the aspects of geometry that all science and engineering graduates have at some time studied. Unfortunately the ‘modern’ material you will now encounter, which is a beautiful combination of ideas from algebra and analysis, has not entirely made it to the common curriculum. So arm yourselves with a paper and pencil0 and begin your excursion. 相似文献

A critical review of research to date suggests a need to explore the development of graduate student research capacity from the standpoint of graduate students. Six members of an interdisciplinary graduate student colloquium at the Centre for Youth and Society (Victoria, Canada) offer their perspective. Our research involved four phases, each illustrating the processes that refined our understanding of the components that contributed to the development of our graduate student research capacity. First, we engaged in several round-table discussions and created a conceptual map depicting components that were meaningful in developing our research capacity. Second, we examined previous work on graduate student research capacity development and compared this data to the conceptual map. Third, we conducted a thematic analysis of secondary data of graduated students with similar interdisciplinary training and involvement in the Centre. Finally, the data analysis was used to refine the conceptual map that may benefit educators and future graduate students. From the standpoint of students themselves, we discuss those components perceived as best contributing to the development of graduate student research capacity and highlight the importance of an interdisciplinary context and writing process. 相似文献
