The way medical students learn anatomy is constantly evolving. Nowadays, technologies such as tablets support established learning methods like drawing. In this study, the effect of drawing on a tablet on medical students' anatomy learning was investigated compared to drawing or summarizing on paper. The quality of drawings or summaries was assessed as a measure of the quality of strategy implementation. Learning outcome was measured with an anatomy test, both immediately afterward and after 4-6 weeks to assess its sustainability. There were no significant group differences in learning outcome at both measurement points. For all groups, there was a significant medium strength correlation between the quality of the drawings or summaries and the learning outcome (p < 0.05). Further analysis revealed that the quality of strategy implementation moderated outcomes in the delayed test: When poorly implemented, drawing on a tablet (M = 48.81) was associated with lower learning outcome than drawing on paper (M = 58.95); The latter (M = 58.89) was related to higher learning outcome than writing summaries (M = 45.59). In case of high-quality strategy implementation, drawing on a tablet (M = 60.98) outperformed drawing on paper (M = 52.67), which in turn was outperformed by writing summaries (M = 62.62). To conclude, drawing on a tablet serves as a viable alternative to paper-based methods for learning anatomy if students can make adequate use of this strategy. Future research needs to identify how to support student drawing, for instance, by offering scaffolds with adaptive feedback to enhance learning.

Today, computer graphics and graphic image processing techniques have been widely used in daily life and industrial production. Due to the development of computers, computer graphics has brought more convenience to our daily life. In order to give full play to the value of computers, this paper takes the Hakka paper-cut art with local characteristics as the starting point, first of all its development history, artistic characteristics, compositional forms, expression techniques, cultural connotations, Hakka paper-cut patterns, and the symbolic meaning of folk customs, and then we design a visualization system for the paper-cut works of Gannan Hakka based on computer graphics. In addition, the system provides a solution for the integration of Gannan Hakka paper-cut art and Jiangxi native product packaging design and provides a reference for the theory and practice of modern native product packaging design., Competing Interests: The author declares that he has no conflicts of interest., (Copyright © 2022 Xingping Li.)

The purpose of this study is to investigate student designers' attitude and choices towards the use of computers and paper sketches when involved in a graphic design process. 65 computer graphic technology undergraduates participated in this research. A mixed method study with survey and in-depth interviews was applied to answer the research questions. This result shows that sketches and computers as design tools help students generate ideas in the early stage of design. Students' preferences to use sketches or computers differ, since each tool has its own advantages and disadvantages.

Personalised written action plans are increasingly regarded as an important component of chronic obstructive pulmonary disease (COPD) self-management support and yet they may not be understood by those with limited literacy skills. This study was designed to produce a comprehensible pictorial COPD action plan for use by patients and health care professionals. With advice from a group of doctors and nurses a 'standard' written COPD action plan was translated by a medical artist into a series of pictorial images. These were assessed using the techniques of guessability and translucency in 21 adults attending a COPD clinic in a London hospital. Guessability and translucency scores show that pictograms were reasonably well understood, with only 3 pictograms showing low score in both guessability and translucency questionnaires. These included images depicting increased sputum production, swollen ankles, and use of extra doses of reliever medication. However, after brief spoken reinforcement about self-management, most patients could use the pictorial plan to suggest appropriate self-management behaviour such as when to access medical care. We have developed a pictorial COPD action plan. Pictorial methods represent an effective method of reinforcing the spoken word for all ranges of literacy.

The purpose of this paper is to examine how infographics are used in the dynamics of designing or creating in the teaching and learning process. Utilising a bibliometric approach and content analysis, we examined a sample of 760 documents from the Web of Science and Scopus databases with no lower time limit until November 2023. The analyses aimed to identify trends, including main topics, authors, sources, most cited articles, institutional affiliations, and countries in the literature. This bibliometric approach allows for the observation of trends in the educational application of promoting visual literacy through students' design or creation of infographics in formal and informal learning settings. Initial publications emerged in 2007, gaining momentum from 2014 to the present. The most prolific fields were medical science, chemistry, and computer science. This investigation shows that educational institutions could employ infographics beyond present boundaries to prepare students--particularly Generation Alpha, digital natives--for a data-driven society. Institutions should expand their use of infographics to improve visual literacy and address the changing educational requirements of students in a dynamic learning environment. Overall, this paper provides insights into the readiness of educators and institutions to engage Generation Alpha, the digital natives, through visual literacy and infographics.

We propose an efficient method to model paper tearing in the context of interactive modeling. The method uses geometrical information to automatically detect potential starting points of tears. We further introduce a new hybrid geometrical and physical-based method to compute the trajectory of tears while procedurally synthesizing high resolution details of the tearing path using a texture based approach. The results obtained are compared with real paper and with previous studies on the expected geometric paths of paper that tears. [ABSTRACT FROM AUTHOR]

This paper proposes an image-based painterly rendering algorithm for automatically synthesizing an image with color ink diffusion. We suggest a mathematical model with a physical base to simulate the phenomenon of color colloidal ink diffusing into absorbent paper. Our algorithm contains three main parts: a feature extraction phase, a Kubelka-Munk (KM) color mixing phase, and a color ink diffusion synthesis phase. In the feature extraction phase, the information of the reference image is simplified by luminance division and color segmentation. In the color mixing phase, the KM theory is employed to approximate the result when one pigment is painted upon another pigment layer. Then, in the color ink diffusion synthesis phase, the physically-based model that we propose is employed to simulate the result of color ink diffusion in absorbent paper using a texture synthesis technique. Our image-based ink diffusing rendering (IBCIDR) algorithm eliminates the drawback of conventional Chinese ink simulations, which are limited to the black ink domain, and our approach demonstrates that, without using any strokes, a color image can be automatically converted to the diffused ink style with a visually pleasing appearance.

Paper pop-ups are interesting three-dimensional books that fascinate people of all ages. The design and construction of these pop-up books however are done manually and require a lot of time and effort. This has led to computer-assisted or automated tools for designing paper pop-ups. This paper proposes an approach for automatically converting a 3D model into a multi-style paper pop-up. Previous automated approaches have only focused on single-style pop-ups, where each is made of a single type of pop-up mechanisms. In our work, we combine multiple styles in a pop-up, which is more representative of actual artist's creations. Our method abstracts a 3D model using suitable primitive shapes that both facilitate the formation of the considered pop-up mechanisms and closely approximate the input model. Each shape is then abstracted using a set of 2D patches that combine to form a valid pop-up. We define geometric conditions that ensure the validity of the combined pop-up structures. In addition, our method also employs an image-based approach for producing the patches to preserve the textures, finer details and important contours of the input model. Finally, our system produces a printable design layout and decides an assembly order for the construction instructions. The feasibility of our results is verified by constructing the actual paper pop-ups from the designs generated by our system. [ABSTRACT FROM AUTHOR]

Ray tracing is a computer graphics technique used to produce realistic visuals by physically simulating the behavior of light. Although this technique can be described straightforwardly, fully comprehending it might be challenging. It is typically taught in the classroom using the 2-D formats, such as paper or a blackboard. We propose using immersive environments for incrementing the understanding of ray tracing. We focus on improving the knowledge of the technique in experienced users, particularly Master of Computer Science students minoring in a computer-graphics-related area. We argue that exploring the ray tracing process in an immersive visualization environment can further improve the understanding of ray tracing acquired using conventional means. With that objective, this study starts by presenting RayTracerVR, a virtual reality prototype tool for learning the mechanisms of ray tracing. This tool can be used to visually explore and interact with the different aspects of the technique. It allows users to observe the progression of the rays throughout the sequential stages of the ray tracing process and analyze its corresponding computer pseudocode. The study includes user evaluation where RayTracerVR is employed to assess improvements in ray tracing understanding. The prototype's usability is also assessed. The findings indicate that using the ray tracing immersive learning environment results in a supplemental increase in understanding in users who have previously learned ray tracing using conventional means.

This paper aims to analyse to what extent the engineering curricula contribute to the development of visual literacy among engineering students. Communicating and thinking visually is a basic skill for all engineers, being a fundamental part of their educational stage. For this purpose, Engineering Graphics subjects from 30 engineering schools from Spain have been selected to review their content. The sample consists of 80 subjects of Engineering Graphics, mechanical design and computer-aided design. The curricula were analyzed using a quantitative and qualitative method. A database has been developed where keywords that identify the objectives of the analysis have been tabulated. Learning technical visual language and visualization skills as a means of developing visual literacy in engineering has been taken as the basis of the analysis. The results show that the curricula of the subjects contemplate the development of graphic skills around communication and technical representation and, to a lesser extent, visualization. On the other hand, the teaching activities contemplated do not dive into the cognitive aspects of graphics. We can also observe the pre-eminence of computer graphics as the main basis for teaching activities and marginal use of freehand drawing, which is basic for the development of Visual Literacy.

Background: Computerized methods to analyze pain drawings (PDs) have been developed and may aid to measure the pain area more precisely. Objective: The aim of this study was to verify whether examiners can reproduce the patient's PDs with acceptable reliability. Methods: This was an intra‐rater and inter‐rater reliability study. The protocol consisted of 4 steps: (1) scanning of paper PDs; (2) sharing the digitalized PD images between examiners; (3) reproducing the PD images in the sketching application; and (4) calculating the pain area in pixels and percentages. We calculated intraclass correlation coefficients (ICCs; 2,1), the standard error of the measurement (SEM), and the smallest detectable difference (SDD). Results: Reliability was tested using 31 PDs from 17 patients in our database (11 female [64.7%], mean age: 53.23 ± 11.57 years). Intra‐rater reliability varied from ICC (2,1) = 0.991 (95% confidence interval [CI] = 0.982 to 0.996; SEM = 3,432.45; SDD = 162.39 pixels; P < 0.001) to ICC (2,1) = 0.992 (95% CI = 0.978 to 0.997; SEM = 3,412.96; SDD = 161.93 pixels; P < 0.001). Inter‐rater reliability for the measurement between all examiners was considered excellent (ICC [2,1] = 0.976; 95% CI = 0.956 to 0.987; SEM =8,580.75; SDD = 256.76 pixels; P < 0.001), being higher between Examiners A and C (ICC [2,1] = 0.970; 95% CI = 0.936 to 0.986; SEM = 6,453.34; SDD = 222.67 pixels; P < 0.001). Conclusion: Our results show that intra‐ and inter‐rater reliabilities were excellent when an examiner reproduced the paper PDs into digitalized PDs. This process gives clinicians and researchers the opportunity to analyze pain extent more precisely using a computerized method. [ABSTRACT FROM AUTHOR]

Analogical thinking is one of the thinking processes that is associated with creativity. This paper explores how it is experienced in Graphic Design elaborations using Computer Graphic Technology (CGT). Data are collected through concurrent and retrospective probing from three undergraduates and analysed through phenomenological reduction to identify the constituents and elements of the creative analogy's general psychological structure. The findings show that the general structure of the creative analogical experience is a relationship between three constituents namely: (1) the experience of recalling knowledge or information; (2) the use of knowledge for ideation; and (3) the use of knowledge to conclude ideas. The findings also show that the underlying elements of these constituents are conceptual (declarative) and technical (procedural) knowledge and its combinations that are consistent with the theories of analogical thinking. This article concludes with recommendations for future research and insights on its implementation in Design Education.

Application-oriented papers provide an important way to invigorate and cross-pollinate the visualization field, but the exact criteria for judging an application paper's merit remain an open question. This article builds on a panel at the 2016 IEEE Visualization Conference entitled "Application Papers: What Are They, and How Should They Be Evaluated?" that sought to gain a better understanding of prevalent views in the visualization community. This article surveys current trends that favor application papers, reviews the benefits and contributions of this paper type, and discusses their assessment in the review process. It concludes with recommendations to ensure that the visualization community is more inclusive to application papers. [ABSTRACT FROM PUBLISHER]

Hospital-acquired conditions such as catheter-associated urinary tract infection, stage 3 or 4 hospital-acquired pressure injury, and falls with injury are common, costly, and largely preventable. This study used participatory design methods to design and evaluate low-fidelity prototypes of clinical dashboards to inform high-fidelity prototype designs to visualize integrated risks based on patient profiles. Five low-fidelity prototypes were developed through literature review and by engaging nurses, nurse managers, and providers as participants (N = 23) from two hospitals in different healthcare systems using focus groups and interviews. Five themes were identified from participatory design sessions: Need for Integrated Hospital-Acquired Condition Risk Tool, Information Needs, Sources of Information, Trustworthiness of Information, and Performance Tracking Perspectives. Participants preferred visual displays that represented patient comparative risks for hospital-acquired conditions using the familiar design metaphor of a gauge and green, yellow, and red "traffic light" colors scheme. Findings from this study were used to design a high-fidelity prototype to be tested in the next phase of the project. Visual displays of hospital-acquired conditions that are familiar in display and simplify complex information such as the green, yellow, and red dashboard are needed to assist clinicians in fast-paced clinical environments and be designed to prevent alert fatigue.

Multimedia will have a profound effect on libraries during the next decade. This rapidly developing technology permits the user to combine digital still images, video, animation, graphics, and audio. It can be delivered in a variety of finished formats, including streaming video on the Web, video on DVD/VCD, embedded digital objects within a Web page or presentation software such as PowerPoint, utilized within graphic designs, or printed as hardcopy. This article examines the elements of multimedia creation, as well as requirements and recommendations for implementing a multimedia facility in the library. [ABSTRACT FROM AUTHOR]

We present a novel appearance model for paper. Based on our appearance measurements for matte and glossy paper, we find that paper exhibits a combination of subsurface scattering, specular reflection, retroreflection, and surface sheen. Classic microfacet and simple diffuse reflection models cannot simulate the double-sided appearance of a thin layer. Our novel BSDF model matches our measurements for paper and accounts for both reflection and transmission properties. At the core of the BSDF model is a method for converting a multi-layer subsurface scattering model (BSSRDF) into a BSDF, which allows us to retain physically-based absorption and scattering parameters obtained from the measurements. We also introduce a method for computing the amount of light available for subsurface scattering due to transmission through a rough dielectric surface. Our final model accounts for multiple scattering, single scattering, and surface reflection and is capable of rendering paper with varying levels of roughness and glossiness on both sides.

Digital heritage portal interfaces are generally similar to digital library and search engine interfaces in displaying search results as a list of brief metadata records. The knowledge organization and search result display of these systems are item-centric, with little support for identifying relationships between items. This paper proposes a knowledge graph system and visualization interface as a promising solution for digital heritage systems to support users in browsing related items, understanding the relationships between items, and synthesizing a narrative on an issue. The paper discusses design issues for the knowledge graph, graph database, and graph visualization, and offers recommendations based on the authors' experience in developing three knowledge graph systems for archive and digital humanities resources: the Zubir Said personal archive collection at the Nanyang Academy of Fine Arts, Singapore; Singapore Pioneers social network; and Polyglot Medicine knowledge graph of Asian traditional and herbal medicine. Lessons learned from a small user study are incorporated in the discussion. [ABSTRACT FROM AUTHOR]

The present situation in Nigeria involves students of fine arts, a practical-oriented subject, being exposed to poor methods of teaching with consequent poor performances. This study examined the extent to which the use of a computerised graphics package could make the classroom technology-oriented and affect the performance of learners. This is predicated on the theoretical frameworks of constructivism and Gagne's learning theory. The research design is the pretest-posttest control group design. The research instruments are the Graphic Design Achievement Test designed from the Revised Minnesota Paper Form Board Test and CorelDraw 10. They were administered to 60 junior secondary school students selected using stratified random sampling. The results show a significant difference in the performance of students exposed to the computerised graphics package as those exposed to the computerised graphics package performed significantly better in graphics than those exposed to the conventional teaching methods.

With restrictions on face-to-face clinical consultations within the COVID-19 pandemic and the challenges faced by healthcare systems in delivering patient care, alternative information technologies like telemedicine and smartphones play a crucial role. A wide variety of smartphone applications employs high-tech mathematical and programming approaches to enhance computer-assisted communication and learning processes' pedagogical efficiency. Accordingly, this study's main objective is to develop a model system that can function as smartphone computer graphics. This paper used the Technology Acceptance Model (TAM) as an m-learning model, and Bresenham's line algorithm is a calculation system implemented by applications. The study method applies technology to validate the accuracy of the contents' acceptance method of use. The results reveal significant positive effects of the proposed model on generating reasonable, fast, and accurate solutions for the presented problems and developing a more interactive platform of m-learning.

Keeping up with rapidly growing research fields, especially when there are multiple interdisciplinary sources, requires substantial effort for researchers, program managers, or venture capital investors. Current theories and tools are directed at finding a paper or website, not gaining an understanding of the key papers, authors, controversies, and hypotheses. This report presents an effort to integrate statistics, text analytics, and visualization in a multiple coordinated window environment that supports exploration. Our prototype system, Action Science Explorer ( ASE), provides an environment for demonstrating principles of coordination and conducting iterative usability tests of them with interested and knowledgeable users. We developed an understanding of the value of reference management, statistics, citation text extraction, natural language summarization for single and multiple documents, filters to interactively select key papers, and network visualization to see citation patterns and identify clusters. A three-phase usability study guided our revisions to ASE and led us to improve the testing methods. [ABSTRACT FROM AUTHOR]

Prototype work can support the creation of data visualizations throughout the research and development process through paper prototypes with sketching, designed prototypes with graphic design tools, and functional prototypes to explore how the implementation will work. One challenging aspect of data visualization work is coordinating the expertise of people from a variety of roles to produce data visualizations guided by an educational theory informed goal (ETIG) in order to better support research. When collaborating, concessions must be made: typically, everyone seeks to follow the best practices established within their own disciplines. This paper attempts to illustrate how to rethink this interdisciplinary approach to adhere more strictly to educational research goals and consider how we may need to, at times, break away from best practices with the intent to evaluate the novel decisions resulting from this approach. A case study of the creation of a self-reported emotional measure is used to illustrate this type of collaboration. By taking this approach, a clear departure from best practices occurs in the scale selection for the visualization in order to support the ETIG.

Young children's growing access to touchscreen technology represents one of many contextual factors that may influence development. The focus of the current study was the impact of traditional versus electronic drawing materials on the quality of children's drawings during the preschool years. Young children (2-5 years, N = 73) and a comparison group of adults (N = 24) copied shapes using three mediums: marker on paper, stylus on touchscreen tablet, finger on touchscreen tablet. Drawings were later deemed codable or uncodable (e.g., scribbles), and codable drawings were then scored for subjective quality on a 4-point scale. Girls and older children (vs. boys and younger children) produced more codable drawings; however, this gap closed when children drew with their finger on a tablet. Medium also affected the quality of adults' drawings, favoring marker on paper. Thus, drawing on a tablet helped younger children produce drawings but resulted in lower quality drawings among adults. These findings underscore the importance of considering environmental constraints on drawing production. Moreover, since clinical assessments often include measures of drawing quality, and sometimes use tablet computers for drawing, these findings have practical implications for education and clinical practice.

Reading scientific papers in portable document format (PDF)-columned formats on computer screens is sometimes daunting and unfriendly. This is mainly due to the fact that PDF-columned texts are often truncated from the top or the bottom of pages so that readers have to scroll up–down repeatedly in the same page to get the whole text read. To make the reading process as smooth as possible, PDF viewers should be designed as responsive tools with responsive layouts that should automatically adapt the amount of readable text to the sizes of the displaying monitors so that readers will not waste time in repetitive vertical and horizontal scrolling movements within the same page. Here, I discuss such a problem-solving proposal that could be implemented in PDF viewers to improve the readability of PDF-columned texts and to make the reading process as flexible and painless as possible.

This paper aims to study English jokes on Facebook. Since the current generation of our students is often described as Net Geners, learning the English language via jokes posted on social media can be one of the supportive ways for EFL learners to improve their L2 linguistic competence as well as L2 humor competence. The data, or jokes, in this study were collected from one of the most popular public pages, entitled "English is Fun". Seventy four jokes (out of 200 posts) from 1 to 16 April 2019 were collected and analyzed. The study result revealed that there were two major types of jokes: one was in a textual form while the other was a mixed-code message, or a combination of verbal and non-verbal elements. The latter was further classified into two subtypes: one had a verbal element as the primary factor to provoke humor while the other required interaction between the verbal element and nonverbal element. In addition, the findings showed that there were four types of logical mechanisms: pun, false analogy, faulty reasoning, and satire. As jokes can be a good source of teaching materials, three possible ways for using jokes in teaching the English language were suggested.

Reviewing literatures for a certain research field is always important for academics. One could use Google-like information seeking tools, but oftentimes he/she would end up obtaining too many possibly related papers, as well as the papers in the associated citation network. During such a process, a user may easily get lost after following a few links for searching or cross-referencing. It is also difficult for the user to identify relevant/important papers from the resulting huge collection of papers. Our work, called PaperVis, endeavors to provide a user-friendly interface to help users quickly grasp the intrinsic complex citation-reference structures among a specific group of papers. We modify the existing Radial Space Filling (RSF) and Bullseye View techniques to arrange involved papers as a node-link graph that better depicts the relationships among them while saving the screen space at the same time. PaperVis applies visual cues to present node attributes and their transitions among interactions, and it categorizes papers into semantically meaningful hierarchies to facilitate ensuing literature exploration. We conduct experiments on the InfoVis 2004 Contest Dataset to demonstrate the effectiveness of PaperVis. [ABSTRACT FROM AUTHOR]

Current desktop technology is largely mouse-driven, but many analysts predict that in less than five years we will have a professional workforce that have only experienced learning in a touchscreen environment. Midland Valley have developed a digital mapping tool for smartphones called FieldMove Clino, which has been downloaded more than 20 000 times over the past year. The free version offers an effective way of introducing students to digital field mapping. However, many geoscience departments and teachers of field mapping have yet to make the switch from traditional paper-based methods to digital technology. This article aims to answer some of the frequently asked questions about digital field mapping and outlines some of the advantages for improving field skills and geological thinking in students.

Game-Based Learning (GBL) is increasingly widespread as a learning technique in the engineering studies. However, this innovative methodology may be difficult to incorporate in some subjects due to their complex contents. This paper aims at combining traditional learning methodologies with game mechanics by using an ad-hoc gaming web environment and mobile devices to analyse the academic performance and motivation in engineering studies. A comparative study was carried out with 96 first-year engineering students. In this experience, the students were randomly divided into two groups: Control Group (CG) and Experimental Group (EG). The first group made use of the traditional learning methodology used, whilst the second group combined the traditional methodology with GBL and Information and Communication Technologies (ICT). The obtained results show that EG students significantly improve their academic performance and motivation, expressing a succinctly greater interest in the studied subject. Therefore, the integration of GBL in the teaching methodology could have a very positive impact as well as it could greatly ease the teaching-learning process in engineering studies.

New and rapidly‐evolving classes of display devices bridge the gap between us and the immersive experiences of the future. The most intimate of these displays are the Virtual‐ and Augmented‐Reality (VR and AR) ones, because they are capable of presenting synthetic environments that rival those in the real world. This ecosystem of personal and highly‐immersive displays offers new challenges for research in computer graphics, display technologies, and human visual perception. While the extensive advancements in the areas of display and computer graphics technologies traditionally end at the on‐screen "image," there are several untapped opportunities for advances that exploit the interplay between the display characteristics and how our visual system perceives them. In this article, we review recent progress in understanding and modeling the perception of immersive displays, as well as perceptually optimizing display technologies for immersive experiences. We present this review in the form of a taxonomy that maps the various properties of modern displays with the perceptual phenomenon that most closely interacts with them. From this taxonomy, we deduce several unsolved challenges in understanding human perception of displays, as well as perceptually‐optimal characteristics of future displays. [ABSTRACT FROM AUTHOR]

We present a novel and effective method for modeling a developable surface to simulate paper bending in interactive and animation applications. The method exploits the representation of a developable surface as the envelope of rectifying planes of a curve in 3D, which is therefore necessarily a geodesic on the surface. We manipulate the geodesic to provide intuitive shape control for modeling paper bending. Our method ensures a natural continuous isometric deformation from a piece of bent paper to its flat state without any stretching. Test examples show that the new scheme is fast, accurate, and easy to use, thus providing an effective approach to interactive paper bending. We also show how to handle non-convex piecewise smooth developable surfaces. [ABSTRACT FROM AUTHOR]

Contribution: Prior studies on tangible versus graphical user interfaces have reported controversial findings concerning children's preferences. This paper shows that their preference profiles in the domain of introductory programming are associated with gender and age for both interfaces. Background: The relevant literature mainly consists of empirical research into the possible advantages and weaknesses of tangible user interfaces versus graphical user interfaces in the domain of programming for children. Research designs have considered aspects of usability, attractiveness and users' collaboration. Existing findings are not clear. Methodological issues, e.g., limitations of simple statistics, may have limited the clarify and usefulness of findings to date. The present study explores children's preferences profiles. Research Questions: Two research questions were posited: the first focused on the latent profiles of children's preferences for the two programming interfaces (tangible or graphical), and the second focused on the association of these profiles with gender and age. Methodology: Children ( N=148 ) aged from six to 13 years old participated in this paper. Eight variables related to the attractiveness, collaboration, and usability factors for the tangible and graphical programming interfaces were measured and analyzed by Latent Class Analysis, a model-based clustering method that can reveal distinct preference-profiles and associate them with individual differences. Findings: The patterns of responses are consistent across items for both interfaces. The graphical programming interface strongly trisects children's preferences profiles; the three latent profiles encountered were associated with gender and age.

Paper architectures are 3D paper buildings created by folding and cutting. The creation process of paper architecture is often labor-intensive and highly skill-demanding, even with the aid of existing computer-aided design tools. We propose an automatic algorithm for generating paper architectures given a user-specified 3D model. The algorithm is grounded on geometric formulation of planar layout for paper architectures that can be popped-up in a rigid and stable manner, and sufficient conditions for a 3D surface to be popped-up from such a planar layout. Based on these conditions, our algorithm computes a class of paper architectures containing two sets of parallel patches that approximate the input geometry while guaranteed to be physically realizable. The method is demonstrated on a number of architectural examples, and physically engineered results are presented. [ABSTRACT FROM AUTHOR]

This will provide a robust foundation to gain valuable insights into articulating the nursing contribution in relation to the design of digital health and progress the nursing contribution to targeted data sources for the advancement of United Nations Sustainable Development Goal Three., (© 2021 Sigma Theta Tau International.)

Health promotional campaign as the practice of encouraging people to improve health has increased over the last decades in response to various health problems. This paper highlights strategies used by students to develop persuasive promotional campaign posters regarding the dengue health problem. Communication and media studies students were involved to show the combined results between the knowledge of health communication and the effective use of media in constructing an effective and persuasive health messages. A total of 56 students from two cohorts, i.e. twenty-five master's students and thirty-one undergraduates were selected. Kurt Lewin's model of action research was used to set the tasks: campaign objectives, information on dengue, themes/slogans to write the posters either by drawing or designing using a computer. The students were divided into groups where each group was monitored to record, check and evaluate their message writing performances. This study uses the Health Message Review Tool for data analysis which is grounded in the theories of Extended Parallel Process Model and Persuasion Hierarchy Effect. The findings revealed that the participants were able to construct, identify and evaluate major multi modal features in the dengue posters and persuasive elements which included: verbal texts, images, colours, graphic designs, metaphors, 1-sided and 2-sided message, firm conclusion and frames with more effective appeals. It was concluded that similar strategies may well be used in producing other campaign materials such as brochures, pamphlets, and billboards. The linguistic and pedagogic implications are also discussed at the end.
