Hands-on dissection-based learning of anatomy offers an unique and valued experience for medical students. Too often however, the inexperienced student's focus is to avoid damage to unfamiliar structures instead of understanding spatial relationships between structures. This results in unfortunate surrender of a critical learning experience. Additionally, approaches to dissection and anatomic exposure share little alignment to clinical approaches, making it less powerful in clinical applicability. The goal of this viewpoint commentary is based on the experience of the two authors and aims to demonstrate opportunity to introduce clinical approaches for dissection while incorporating relevant anatomical concepts in medical school curriculum that aligns with authentic healthcare practice. Using the dissections of the superficial face as a relevant and current topic of clinical interest, we point out that applying the currently performed dissection approach (medial-to-lateral) falls short of providing sufficient knowledge and understanding of the layered arrangement of facial structures. The lateral-to-medial approach, as performed in surgical face lifting procedures would offer a better understanding of the layers of the face and especially the superficial musculoaponeurotic system (SMAS) accounting for the difficulties of facial dissections on embalmed cadavers. This commentary could offer a potential change in paradigm for students and course facilitators for how to maximize the knowledge transfer during facial dissections. It potentially opens a door to rethink dissection-based learning of anatomy toward techniques and approaches that are aligned to surgical access pathways and thus considered more clinically relevant. 相似文献

Sample based 3D face reconstruction from a single frontal image by adaptive locally linear embedding 总被引：1，自引：0，他引：1

In this paper, we propose a highly automatic approach for 3D photorealistic face reconstruction from a single frontal image. The key point of our work is the implementation of adaptive manifold learning approach. Beforehand, an active appearance model (AAM) is trained for automatic feature extraction and adaptive locally linear embedding (ALLE) algorithm is utilized to reduce the dimensionality of the 3D database. Then, given an input frontal face image, the corresponding weights between 3D samples and the image are synthesized adaptively according to the AAM selected facial features. Finally, geometry reconstruction is achieved by linear weighted combination of adaptively selected samples. Radial basis function (RBF) is adopted to map facial texture from the frontal image to the reconstructed face geometry. The texture of invisible regions between the face and the ears is interpolated by sampling from the frontal image. This approach has several advantages: (1) Only a single frontal face image is needed for highly automatic face reconstruction; (2) Compared with former works, our reconstruction approach provides higher accuracy; (3) Constraint based RBF texture mapping provides natural appearance for reconstructed face. 相似文献

中国戏曲脸谱带有浓重的巫术色彩,随着戏曲政治化的发展,这种巫术色彩逐渐被专制主义者所利用,形成了脸谱艺术虚假性、仪式性、游戏性、神秘性的特征。脸谱艺术是戏曲政治化过程中政治化最明显、最深刻、最有影响的元素。这种影响不仅是物质上建立了一套以特定面貌表现特定人物性格品质的体系,而且在精神上将人的形象与真实的社会分离,成为主流意识形态的代名词,并随着戏曲的广泛流传对中国人的思想观念和价值取向产生了影响。 相似文献

Although recent studies have convincingly demonstrated that emotional expressions can be judged reliably from actor-posed facial displays, there exists little evidence that facial expressions in lifelike settings are similar to actor-posed displays, are reliable across situations designed to elicit the same emotion, or provide sufficient information to mediate consistent emotion judgments by raters. The present study therefore investigated these issues as they related to the emotions of happiness, surprise, and fear. 27 infants between 10 and 12 months of age (when emotion masking is not likely to confound results) were tested in 2 situations designed to elicit hapiness (peek-a-boo game and a collapsing toy), 2 to elicit surprise (a toy-switch and a vanishing-object task), and 2 to elicit fear (the visual cliff and the approach of a stranger. Dependent variables included changes in 28 facial response components taken from previous work using actor poses, as well as judgments of the presence of 6 discrete emotions. In addition, instrumental behaviors were used to verify with other than facial expression responses whether the predicted emotion was elicited. In contrast to previous conclusions on the subject, we found that judges were able to make all facial expression judgments reliably, even in the absence of contextual information. Support was also obtained for at least some degree of specificity of facial component response patterns, especially for happiness and surprise. Emotion judgments by raters were found to be a function of the presence of discrete facial components predicted to be linked to those emotions. Finally, almost all situations elicited blends, rather than discrete emotions. 相似文献

Summary It is impossible to use any single discipline technique without including aspects of other techniques. Tone of voice and facial expression impinge on what is said. To avoid communicating conflicting messages adults should strive for consistency. The environment, body language and verbal and social response should combine to communicate a similar message to the child.Perhaps another way to approach the interaction of all techniques is the eclectic approach. Overuse of a technique is not a problem with the eclectic approach. Through this approach one can adapt a variety of techniques into a system to fit the individual adult and the individual child.Ronald K. Mullis and Ann K.

Children's integration of facial and situational cues to emotion 总被引：1，自引：0，他引：1
Children at 4 age levels (3-5, 6-7, 8-9, and 10-12 years) were shown a series of pictures in which facial and situational cues were (a) congruent, (b) conflicting, or (c) presented alone. Children rated the type (happy or sad) and intensity of the emotion felt by each character. Developmental changes in the relative weights assigned to facial and situational cues were examined using Anderson's information integration approach. The results showed that children's reliance on situational cues increased with age, but their reliance on facial expression decreased with age. Analysis of individual children's ratings indicated a developmental increase in the tendency to integrate facial and situational cues. Children's ability to resolve the conflicting cues (through stories) also increased with age, but there were no age differences in the types of resolutions used. At all age levels, children were less likely to resolve pictures involving an inconsistent positive expression than pictures showing an inconsistent negative expression. 相似文献
