    胸部X射线(CXR)在临床实践中被广泛用于促进重症和急诊患者的诊断和治疗。基于后前(P-A)CXR图像的准确半隔膜检测对于危重和急诊患者的隔膜功能评估至关重要,从而为这些脆弱人群提供精确的医疗保健。
    因此,迫切需要一种有效且准确的P-ACXR图像半隔膜检测方法来评估这些脆弱人群的隔膜功能。
    基于上述内容,提出了一种有效的基于卷积神经网络(CNN)和图形的P-ACXR图像半膜片检测方法。首先,我们开发了一种健壮的标准的病理肺CNN模型,该模型由患有多种肺部疾病的正常和异常病例的人类P-ACXR图像训练,以从P-ACXR图像中提取肺野。第二,我们提出了一种基于左右两个肺的二维投影形态的心膈角的定位方法,用于通过图形检测半膈。
    从基于五种不同分割模型的静态P-ACXR图像中提取的肺野掩模图像中四个关键半膈点的平均误差分别为9.05、7.19、7.92、7.27和6.73像素,分别。此外,结果还表明,基于这些分割模型从动态P-ACXR图像中提取的肺野掩模图像中这四个关键半隔膜点的平均误差分别为5.50、7.07、4.43、4.74和6.24像素,分别。
    我们提出的半隔膜检测方法可以有效地进行半隔膜检测,并可能成为评估这些脆弱人群\'隔膜功能的有效工具,以进行精准医疗。
    UNASSIGNED: Chest X-rays (CXR) are widely used to facilitate the diagnosis and treatment of critically ill and emergency patients in clinical practice. Accurate hemi-diaphragm detection based on postero-anterior (P-A) CXR images is crucial for the diaphragm function assessment of critically ill and emergency patients to provide precision healthcare for these vulnerable populations.
    UNASSIGNED: Therefore, an effective and accurate hemi-diaphragm detection method for P-A CXR images is urgently developed to assess these vulnerable populations\' diaphragm function.
    UNASSIGNED: Based on the above, this paper proposes an effective hemi-diaphragm detection method for P-A CXR images based on the convolutional neural network (CNN) and graphics. First, we develop a robust and standard CNN model of pathological lungs trained by human P-A CXR images of normal and abnormal cases with multiple lung diseases to extract lung fields from P-A CXR images. Second, we propose a novel localization method of the cardiophrenic angle based on the two-dimensional projection morphology of the left and right lungs by graphics for detecting the hemi-diaphragm.
    UNASSIGNED: The mean errors of the four key hemi-diaphragm points in the lung field mask images abstracted from static P-A CXR images based on five different segmentation models are 9.05, 7.19, 7.92, 7.27, and 6.73 pixels, respectively. Besides, the results also show that the mean errors of these four key hemi-diaphragm points in the lung field mask images abstracted from dynamic P-A CXR images based on these segmentation models are 5.50, 7.07, 4.43, 4.74, and 6.24 pixels,respectively.
    UNASSIGNED: Our proposed hemi-diaphragm detection method can effectively perform hemi-diaphragm detection and may become an effective tool to assess these vulnerable populations\' diaphragm function for precision healthcare.

    目的:我们试图分析健康概率数据(如疾病或副作用的机会)的交互式可视化和动画,这些数据在静态图形或数字通信的头对头比较中进行了研究。
    方法:关于健康中的数字交流方法的大型系统综述的二次分析。
    结果:我们对研究进行了分组,以表明多种研究人员已经研究了4种类型的动画或交互式可视化:模拟概率事件的经验的;那些证明这些事件的随机性的;那些通过将注意力依次引导到不同的信息项来减少信息过载的;以及那些促进精细思维的。总的来说,这4种可视化并没有显示出提高理解力的有力证据,风险感知,或静态图形上的健康行为。
    结论:目前还没有强有力的证据表明,交互性或动画在传达健康概率方面比静态图形更有效。我们讨论了两种可能性:最有效的可视化尚未被研究,并且可视化效果无效。
    结论:未来的研究应严格比较参与者的表现与新颖的交互式或动画可视化与静态可视化的表现。这些证据将有助于确定健康传播者是否应该强调新颖的交互式可视化或依赖较旧的视觉交流形式,更广泛的受众可以接触到,包括那些有限的数字访问。
    OBJECTIVE: We sought to analyze interactive visualizations and animations of health probability data (such as chances of disease or side effects) that have been studied in head-to-head comparisons with either static graphics or numerical communications.
    METHODS: Secondary analysis of a large systematic review on ways to communicate numbers in health.
    RESULTS: We group the research to show that 4 types of animated or interactive visualizations have been studied by multiple researchers: those that simulate experience of probabilistic events; those that demonstrate the randomness of those events; those that reduce information overload by directing attention sequentially to different items of information; and those that promote elaborative thinking. Overall, these 4 types of visualizations do not show strong evidence of improving comprehension, risk perception, or health behaviors over static graphics.
    CONCLUSIONS: Evidence is not yet strong that interactivity or animation is more effective than static graphics for communicating probabilities in health. We discuss 2 possibilities: that the most effective visualizations haven\'t been studied, and that the visualizations aren\'t effective.
    CONCLUSIONS: Future studies should rigorously compare participant performance with novel interactive or animated visualizations against their performance with static visualizations. Such evidence would help determine whether health communicators should emphasize novel interactive visualizations or rely on older forms of visual communication, which may be accessible to broader audiences, including those with limited digital access.

    1960年代,通过使用计算机生成的随机点立体图,对立体深度感知的研究进行了转换。他们实现了Wheatstone希望在没有单目物体识别的情况下展示双目深度,从那时起,它们一直是研究立体视觉的主要刺激因素。替代载体图案的随机点,基于图形,照片,以及它们的组合,被呈现为原位和自由融合。这些替代方案可以揭示更广泛的隐藏模式,并将它们呈现为anaglyphs可以产生具有视觉吸引力的图案,而与它们隐藏的深度无关。
    Investigations of stereoscopic depth perception were transformed via the use of computer-generated random-dot stereograms in the 1960s. They realized Wheatstone\'s wish of demonstrating binocular depth without monocular object recognition, and they have been the dominant stimulus for studying stereopsis since then. Alternative carrier patterns to random dots, based on graphics, photographs, and their combinations, are presented as anaglyphs and for free fusion. A wider range of concealed patterns can be revealed with these alternatives, and presenting them as anaglyphs can yield patterns that have visual appeal independent of the depth they conceal.

    目的:本研究旨在分析和量化15种基础和临床护理教科书中深色肤色(DST)图像/图形的表示,以了解当前护理文本中描绘的多样性程度。
    背景:美国(美国)人口在种族和种族上变得越来越多样化。护理文献很少,研究,以及有关深色肤色(DST)患者常见皮肤评估的评估和早期识别的教育材料。在教学材料中使用DST图像的人的代表性不足表明,在教育资源中遗漏这些图像可能会在医疗保健提供者的教育和实践中引入偏见。
    方法:选择15本流行的基础和临床护理教材进行分析。这些教科书中的所有照片图像和绘制的图形都是根据菲茨帕特里克的皮肤照型(FSP)量表编码的,将肤色分类为(a)“轻”或Fitzpatrick量表I或II,(b)“中等”或Fitzpatrick量表III或IV,和(c)“黑暗”或Fitzpatrick刻度V或VI。在分析之前为数据收集者提供了培训,以确定良好的评分者间可靠性(对于浅肤色,科恩的kappa=0.960,Cohen\'skappa=0.899,适用于中等肤色,和Cohen\的kappa=0.913的深色肤色)。
    结果:在15个基础和临床护理教科书中完成了14,192张照片图像和描绘肤色的绘制图形的分析。12.3%的照片图像和2.4%的绘制图形描绘了深色肤色,相比之下,这些教科书中60.9%的照片图像和82.8%的绘制图形显示浅色肤色。
    结论:护理教科书夸大了浅肤色,而低估了深色肤色。虽然美国人口的大致种族分布是59.3%的非西班牙裔白人,13.6%黑人/非洲裔美国人,和26.6%的有色人种,肤色的图像和图形代表了68%的光,15%培养基,和9.4%的黑暗。
    结论:所有医疗保健提供者都被期望并要求为日益多样化的人群提供称职的临床护理。对于教学,DST的更多视觉表示和在黑暗中期望的比较图像,中等,浅肤色可以帮助改善知识不足和增加健康公平。
    OBJECTIVE: This study aimed to analyze and quantify the representation of dark skin tones (DST) images/graphics across fifteen foundational and clinical nursing textbooks to understand the degree of portrayed diversity in current nursing texts.
    BACKGROUND: The United States (U.S.) population is becoming more ethnically and racially diverse. There is a scarcity of nursing literature, studies, and educational materials on the assessment and early recognition of common skin assessment in patients with dark skin tones (DST). The underrepresentation of people with DST images in didactic material suggests that omissions of these images in educational resources may introduce bias in health care provider education and practice.
    METHODS: Fifteen popular foundational and clinical nursing textbooks were selected and analyzed. All the photo images and drawn graphics in these textbooks were coded according to Fitzpatrick\'s skin phototype (FSP) scale, which categorizes skin tone as (a) \"Light\" or Fitzpatrick scale I or II, (b) \"Medium\" or Fitzpatrick scale III or IV, and (c) \"Dark\" or Fitzpatrick scale V or VI. The training was provided for data collectors before analysis to ascertain good inter-rater reliability (Cohen\'s kappa = 0.960 for light skin tone, Cohen\'s kappa = 0.899 for medium skin tone, and Cohen\'s kappa = 0.913 for dark skin tone).
    RESULTS: Analysis of 14,192 photo images and drawn graphics depicting skin tone was completed across 15 foundational and clinical nursing textbooks. 12.3 % of photo images and 2.4 % of drawn graphics depicted dark skin tones, compared to 60.9 % of photo images and 82.8 % of drawn graphics that displayed light skin tones in these textbooks.
    CONCLUSIONS: Nursing textbooks overrepresent light skin tones and underrepresent dark skin tones. While the approximate racial distribution of the U.S. population is 59.3 % non-Hispanic-White, 13.6 % Black/African American, and 26.6 % Person of Color, the images and graphics of skin tones represented 68 % light, 15 % medium, and 9.4 % dark.
    CONCLUSIONS: All healthcare providers are expected and required to deliver competent clinical care to an increasingly diverse population. For teaching-learning, more visual representations of DST and comparative images between what to expect in dark, medium, and light skin tones can help improve knowledge deficits and increase health equity.

    本文提出了一种新颖的体系结构,该体系结构可从连续图像流的网格中生成世界模型,该图像流具有从机器人的自我视觉相机中提取的深度信息。我们提出了两种平面和非平面网格生成算法。提出了一种基于笛卡尔网格的网格拟合算法,用于平面物体的网格生成。对于非平面对象的网格生成,提出了一种基于自组织映射的算法。与最新技术(SOA)相比,所提出的算法更好地接近对象的边界和整体形状。在三个公共数据集上进行的大量实验表明,我们的方法在定性和定量上都超过了SOA。
    This paper presents a novel architecture to generate a world model in terms of mesh from a continuous image stream with depth information extracted from a robot\'s ego-vision camera. We propose two algorithms for planar and non-planar mesh generation. A Cartesian grid-based mesh fitting algorithm is proposed for mesh generation of planar objects. For mesh generation of non-planar objects, we propose a Self Organization Map based algorithm. The proposed algorithm better approaches the boundary and overall shape of the objects compared to State-Of-the-Art (SOA). Extensive experiments done on three public datasets show that our method surpasses SOA both qualitatively and quantitatively.

    Illustrated review articles, rooted in scientific rigor, are made up of \"capsules\" or panels of visuals that together provide an up-to-date overview of a topic. Illustrated reviews aim to provide a more accessible format than traditional written reviews to facilitate more effective knowledge translation and dissemination. However, the novelty of this format can dissuade prospective authors due to uncertainty and lack of comfort. To remedy this uncertainty, we have summarized the journey of developing an illustrated review, from identifying an appropriate topic to submitting the final manuscript for peer review. We highlight the importance of approaching an illustrated review from a storytelling perspective, and encouraging authors to keep their audience in mind when picking a theme or characters. We provide storyboard considerations and simplify graphic design principles to develop an outline and line draft for the illustrated review. We list programs available to authors to demystify creating attractive and engaging scientific visuals. Finally, we provide information on choosing colors or fonts and where to find copyright-free icons, graphics, illustrations, and pictures. This review provides prospective authors with the knowledge, tools, and resources to create an effective illustrated review article.

    尽管环境影响评估(EIA)一直是环境决策的重要工具,大多数EIA是作为文本和表格数据的混合发布的,公众不容易访问或理解。在本文中,我们提出了一个决策支持系统(DSS),支持EIA阶段的利益相关者的决策。该系统旨在通过提供关键环境要素的可视化来提高公众对建设项目前后利益相关者的理解。我们招募了107名参与者来测试系统的可用性,并检查了参与者之间的个体差异对他们对系统的看法的影响。包括他们的环境专业知识和计算机自我效能感。结果表明,该系统具有较高的可用性,特别是对于具有高计算效率和环境专业知识的用户。因此,该系统可以帮助在公开听证会期间改善公众与专家之间的沟通,并提高公众的环境素养。
    Even though environmental impact assessments (EIAs) have been an important tool for environmental decision-making, most EIAs are published as a mix of text and tabular data that is not easily accessible to or understandable for the public. In this paper, we present a decision support system (DSS) that supports the decision-making of stakeholders in the EIA stage. The system was designed to improve the public\'s understanding of stakeholders before and after a construction project by providing visualization of key environmental elements. We recruited 107 participants to test the usability of the system and examined the impacts of individual differences between the participants on their perceptions of the system, including their environmental expertise and computer self-efficacy. The results showed that the proposed system had high usability, especially for users with high computational efficacy and environment expertise. The system could thus help to improve the communication between the public and experts during public hearings and enhance the environmental literacy of the public.
