The influence of adhesive creams on the period of adaptation to removable dentures

Adentia, whether partial or complete, is a common condition in the population, especially among older individuals. Although removable orthodontic devices are an effective solution for adentia, dentures can cause irritation in the oral cavity. The nature and duration of symptoms experienced by patients using dentures for the first time depend on various factors, such as the condition of their teeth and gums, jaw bone density, prosthesis design, psychological factors, and previous dental work. Studies have shown that special adhesive agents can improve the fit of removable dentures, leading to faster adaptation and better stability, even in challenging oral conditions. Using adhesives not only helps with new prostheses but also enhances comfort with existing ones, reduces movement while eating, and prevents food from getting trapped under the denture. This ultimately improves the patient's psychological well-being, reduces the foreign body sensation, and enhances quality of life. Proper maintenance and use of removable dentures can prevent jaw bone atrophy and degenerative changes in the oral tissues. Literature review revealed the numerous variables that impact the successful treatment of total or partial tooth loss in patients. The incorporation of bonding agents unquestionably enhances the adjustment process to removable orthodontic devices by enhancing stability, a critical factor in the early stages of prosthesis use. However, it is essential to consider other various factors that influence the complexity and duration of adaptation, such as the characteristics of the dental structure, oral mucosa condition, jaw bone atrophy level, prosthesis selection and design, patient's psychological state, presence of macroglossia, previous prosthetic work, or its absence.

AI assistance in enterprise UX design workflows: enhancing design brief creation for designers

The study explores the impact of AI tools on the daily tasks of designers in corporate environments, with a focus on the creation and evaluation processes of design briefs. Given ChatGPT’s advanced natural language processing capabilities and its potential to meet the complex communication and analysis needs of design work, this tool was selected to investigate its application in designers’ workflows. Through expert interviews, experimental testing, and third-party expert evaluations, we collected and analyzed data to understand the impact of AI on work processes. The findings indicate that AI tools significantly enhance both operational experience and subjective perceptions across most tasks. Additionally, the study provides a visual comparison of the testing process through a user experience map, highlighting AI’s positive influence on work efficiency, information retrieval, verification, analysis, communication, and decision-making. However, challenges remain in ensuring information authenticity, protecting content copyright, and maintaining professional identity. The primary objective is to gain a comprehensive understanding of the current state of AI application in business contexts and its impact on designers’ roles. By analyzing real-world feedback, the research aims to identify the strengths and weaknesses of AI solutions in enterprises and offer practical recommendations. The study underscores the importance of integrating AI thinking into workflows and adopting a human-centric approach for the future development of corporate work environments.

Learning designers

The contemporary post-digital university is ever more dependent on the expertise and labour of ‘third space’ professionals such as learning designers. Reporting on the initial findings of a recent survey, this paper presents a snapshot of the people who do the work of learning design, their perspectives on their work and their contributions to teaching and learning in higher education. Four defining characteristics emerged through thematic analysis of 90 survey responses: 1) learning designers come from varied academic and professional backgrounds; 2) our job functions, working conditions and organisational settings can vary significantly; 3) our work practices—and so the knowledge and skills required for the role—can be highly diverse; 4) despite the variety, a shared motivation and sense of purpose is shaping emergent professional identities. Adopting a socio-material lens, this paper presents a rich picture of an expanding profession, providing vital insights into the practices, identities, and impact of learning designers.

Considerations in Acquisition of 3D-Printed Art

ABSTRACT 3D printing (also known as Rapid Prototyping or Additive Manufacture) is increasingly common and technically sophisticated, and is utilized in art and design, industry, and consumer applications. Museums and collectors are now acquiring works made using this technology though their preservation needs are not fully understood. This article provides an overview of the technology and related terminology, review of related conservation literature, and introduction to current efforts for the care of these works. Discussion includes the formulation of collaborative working practices, documentation during acquisition, and consideration of periodic reprinting. Case studies include a pre-accession checklist developed at SFMOMA (San Francisco Museum of Modern Art) and the reprinting of select components from Altar/Engine (2015) by Tauba Auerbach at MoMA (Museum of Modern Art) in New York. Though 3D-printed works may be found in science, history, and other collections, this study will focus on works of contemporary art and design.

Harmonizing data across the accelerating colorectal cancer screening and follow-up through implementation science (ACCSIS) program to enhance data quality and promote data sharing

BackgroundThe purpose of the Accelerating Colorectal Cancer Screening and Follow-up through Implementation Science (ACCSIS) Program, a Cancer Moonshot℠ Initiative, is to support research to build the evidence base on multilevel interventions that increase rates of colorectal cancer screening, follow-up, and referral to care to address disparities in colorectal cancer screening. The National Cancer Institute funded eight Research Projects to implement multilevel interventions to improve colorectal cancer screening among communities who traditionally have been medically underserved. To analyze the impact of ACCSIS across Research Projects, the consortium developed a set of common data elements. The purpose of this paper is to describe the process of developing the common data elements to facilitate analysis of ACCSIS data as well as support and inform implementation science research studies.MethodsThe ACCSIS Data, Design, and Analysis Work Group was tasked with designing common data elements through a review of existing data collection instruments, examination of data elements proposed by the ACCSIS Research Projects, and deliberations on the data required to compare across the Research Projects. ACCSIS Consortium members drafted, revised, and finalized a common data elements document consisting of variables to collect and surveys to administer to evaluate ACCSIS implementation activities and outcomes in a standardized manner across the Research Projects.ResultsThe ACCSIS Consortium decided to collect the following categories of common data elements: characteristics across multiple levels of the multicomponent interventions, implementation climate, and determinants; interventions and strategies; implementation outcome constructs and definitions; colorectal cancer screening episodes (screening, diagnostic testing follow-up, cancer detection, and cancer treatment); and cost measures. To assess implementation climate, the consortium prioritized constructs from five domains of the Consolidated Framework for Implementation Research.ConclusionsThe ACCSIS common data elements offer a set of harmonization data for future implementation efforts. The consortium is conducting a systematic assessment using both quantitative and qualitative approaches to assess data quality and approaches to improve and sustain data collection. Lessons learned from these ongoing activities will offer additional insights to tailor the ACCSIS common data elements and support efforts to increase colorectal cancer screening for populations experiencing disparities.

Numerical analysis of fixed-end hollow rectangular beam under uniformly distributed load

The purpose of using opening in the reinforced concrete (RC) rectangular beam is the reduction of self-weight, cost, displacement, and strain. Therefore, this research performs linear elastic finite element analysis by using ETABS for fixed-ended RC hollow and solid rectangular beams under uniformly distributed loadings with variable beam lengths, compressive strengths, and opening sizes.The solid and hollow beams are considered to be a 2-nodded line element for the numerical analysis. The maximum range of validation result in case of hollow beam is found to be (3.9 to 7.9) %, which may indicate good accuracy of numerical analysis. The 50 × 50 mm opening size is suitable for 300 × 300 mm RC rectangular beam because of showing the positive normalized deflection of (0–1.45) % and lower strain rates (i.e. 0.13 % and 0.17 %) to compare the solid beam. This research may help professional engineers to use suitable opening size for design and construction works. Although, there is a scope to enhance this research in future by performing nonlinear analysis.

The design of high-brightness ERL-FEL injector based on VHF electron gun

In the past decade, the fourth-generation light source based on the combination of Energy Recovery Linac (ERL) and Free-Electron Laser (FEL) using superconducting linear accelerators has garnered significant attention. It holds immense potential, particularly in generating high-power Extreme Ultraviolet (EUV) light sources. This article primarily focuses on the physical design of an injector for ERL-FEL, based on a Very High Frequency (VHF) electron gun with a charge of 100 pC. The beam energy is accelerated to 10 MeV using 3-cell superconducting cryomodule. The optimization of beam parameters is conducted through employment of BMad and ASTRA simulations, incorporating the concept of Merger optimization. The beam emittance is less than 0.6 mm mrad, and the peak current at the injector exit exceeds 18 A. We present a new method to evaluate the Longitudinal Space Charge (LSC) effects in merger sections, which can be readily applied in design work. Furthermore, we introduce a novel type of merger. The performance of this new merger is comparable to the previously known optimum, the zigzag merger, offering a potential alternative solution for injectors in ERLs.

The Interior Contact-Aided Rolling Element

Abstract This work introduces an interior contact-aided rolling element (I-CORE) compliant mechanism that draws upon the concepts used for the contact-aided rolling element, cross-axis flexural pivot, and pre-curved flexible beam. The I-CORE incorporates a bilinear compressive stiffness response with an initial tailorable stiffness governed by the flexural geometry, followed by a stiffness curve governed by the material stiffness at the contact point. The I-CORE mechanism can achieve one or two degrees of rotational freedom as well as a single degree of translational freedom. The purpose of the present work was to introduce the I-CORE mechanism, as well as a pseudo-rigid-body replacement model (PRBM) of the I-CORE mechanism which was subsequently validated using both finite element analysis and benchtop mechanical testing. A pseudo-rigid body model was created for the I-CORE to simplify the rapid adaptation of this mechanism to different design applications. This model was validated using both finite element analysis and benchtop mechanical testing under both compression and rotation loading conditions. Additionally, multiple configurations of the device were created and evaluated in order to test its sensitivity to certain design features including the flexure width, flexure thickness, and the radius of the rounded contact surfaces. It was found that the model is sensitive to the thickness of the flexures and that despite some limitations, the pseudo-rigid body model is sufficiently accurate for initial design work. Some possible applications of the mechanism are proposed.

An iterative model for the development of an urban development strategy – a case study of Polanica-Zdrój (Poland)

Motives: The current approach to the design of public space in cities is changing due to the global situation, i.e., the climate and health crisis, as manifested by the COVID 2019 pandemic. There is a need to develop and apply new, innovative research methods and techniques that allow both an in-depth knowledge of a given area and the monitoring of the changes that occur in this area. One of the proposals for such a framework is an iterative model based on the results of the analyses carried out during the research and design work using the research through design (RtD) method.Aim: The aim of this study was to determine the applicability of the iterative process model for the development of urban strategy, particularly in terms of designing more resilient urban public spaces.Results: The iterative process model was tested during consultation meetings on the development strategy for the municipality of Polanica-Zdrój. The design concepts developed during the research were an excellent support for illustrating the goals of the spatial policy of the municipality of Polanica-Zdrój as specified in the draft of its development strategy. They became the starting point for the future design process. A project with blue-green infrastructure (BGI) elements was included in the draft development strategy as an exemplary project for the development and modernization of tourism and tourism-related infrastructure of a supra-local, infrastructural and linear nature. A study using the RtD method supported the identification of opportunities and limitations associated with the implementation of BGI in the protected urban areas.

Modal testing and analysis of high-rise laminated timber building

To enhance the design and research work on dynamic characteristics of high-rise laminated timber buildings, this paper carried out a modal analysis study on one of the largest laminated timber buildings in China. The finite element calculating modal analysis was carried out using SAP2000 software, and the experimental modal analysis of the building was carried out via environmental excitation. The calculating modal results and the experimental modal results showed good agreement. The calculating modal frequency values were generally lower than the experimental modal frequency values. The natural frequencies obtained by the two methods appeared in the Y-direction first-order bending mode and had values of 2.03 and 2.5 Hz, respectively. The corresponding frequencies of the first-order torsional mode were 2.82 and 3.25 Hz, respectively. The distribution of the CLT core tube along the length direction of the building has an impact on the vibration mode. The six-story part shows the second-order bending form, while the four-story section only shows the first-order bending form. The above work provides a case study and reference for the simulation and modal analysis of high-rise laminated timber buildings, demonstrating the critical role of the core tube structure in such wooden buildings. This insight contributes to a better understanding of structural performance and design considerations in similar projects.

Enhancing instructional design learning: a comparative study of scaffolding by a 5E instructional model-informed artificial intelligence chatbot and a human teacher

ABSTRACT To address the limitations of general-purpose artificial intelligence (AI) tools, we developed a task-oriented AI chatbot based on the 5E (i.e. “engage”, “explore”, “explain”, “elaborate” and “evaluate”) model to scaffold students’ instructional design process. We examined the impact of integrating the 5E instructional model-informed AI chatbot on students’ learning performance and perceptions. The results indicated that the AI chatbot, when combined with human teacher scaffolding, significantly improved the students’ instructional design performance relative to receiving human teacher scaffolding only. The chatbot provided valuable suggestions on instructional design frameworks, class activities and teaching topics during the “explore” phase. In the “evaluate” phase, the chatbot offered immediate feedback on the students’ design plans and proposed alternative instructional frameworks regarding areas for improvement. However, the students expressed concerns about the chatbot’s evaluation quality, noting that it needed to be better aligned with the course assessment rubric. We recommend using AI chatbots for instructional design conceptualisation, although we emphasise the critical role of human teachers in evaluating final design work and providing timely support.

Lessons Learned from Offering Video Visits as an Alternative to Phone Visits: A Case Study from a Safety-Net Obstetrics Clinics.

Before the Covid-19 pandemic, human-centered design work in San Francisco found video visits promising for Medicaid-insured pregnant individuals. They were deemed likely better than phone at addressing concerns about remoteness. We describe our experience with introducing video visits within a safety net clinic that had rapidly adopted phone visits as the standard telemedicine option early in the pandemic. By utilizing Kotter's change framework, providing an equity-focused vision, and supporting the implementation with a skilled, on-the-ground project manager, temporary uptake of offering video visits was achieved. However, competing priorities, staffing structure, and institutional culture were barriers to creating sustained change once grant funding ended, even after improvement of digital infrastructure. Efforts to increase video visit uptake in systems where telephone visits are the norm-as is in many safety net systems-may have limited success without leadership-driven prioritization and culture change at all levels.

Database Analysis of Long-Term Settlement Behavior of Pile Foundations in Shanghai Soft Coastal Clays

A database of 195 field records of long-term settlement of high-rise buildings in Shanghai soft coastal clays is presented. The collected field records are divided into two categories based on pile type, i.e., bored pile and precast pile. Based on the settlement recorders collected, the long-term settlement behavior and settlement duration of the pile foundations in soft coastal clays are investigated. The statistical results show that the pile foundation in Shanghai soft coastal clays can be divided into three kinds of site conditions by considering the pile length and variation of long-term deformation behavior. Prediction models based on the power function are proposed to calculate the normalized final settlement for both bored pile and precast pile foundations. Based on the statistical results, the average normalized final settlement (settlement per floor), average settlement ratio (final settlement to the settlement when the superstructure is completed), and average settlement duration in the three site conditions for both bored pile and precast pile foundations are given. Additionally, an exponential settlement prediction model that can accurately forecast the entire settlement and post-construction settlement characteristics of buildings in Shanghai’s soft soil area is proposed. These statistical results can be referred to the preliminary foundation design works, which contribute to the quick evaluation of the possible settlement range, settlement ratio, and settlement duration of the proposed building constructed in the soft coastal clay area in Shanghai.

Interior Fabrications: rethinking the interior through hands-on prototyping

Exploring the intersection between design education and hands-on experience in real-world construction scenarios, this study seeks to address the gap between design concepts and their practical execution. An experimental seminar titled Interior Fabrications was invented to integrate construction knowledge with a theoretical investigation. First exposed to a range of tools and techniques through participation in a real-world design-build exercise, the students were then asked to deploy their skills within their own design work. Students considered how new typologies of interior partitions could impact spatial dynamics, the relationship between identity and the interior, and create new programmatic consequences. Physical engagement with materials and space allowed for new experimentation and ways of thinking about design, creating a stronger awareness and understanding of the built environment. The study focuses on the value of learning and experimenting through full-scale mock-ups of materials.

Планово-высотная параметризация типов рельефа для диагностики опасных гравитационных процессов

The authors present the results of a comprehensive geomorphological analysis of the mountain relief types in the middle part of the Verkhnyaya Angara basin (lake Baikal region) for geoinformation diagnostics of dangerous gravitational processes. The relevance of the study is due to the increasing importance of the Baikal-Amur Mainline; the novelty lies in the fact that a high-precision plane-and-height assessment of the Baikal basin northern part’s hard-to-reach areas. The physical and geographical characteristics of the studied territory are given, tectonic and geological features of the relief formation are indicated. For the metric assessment and subsequent mapping of the terrain in the Arc GIS software environment, a digital model of the studied territory and raster coverings of morphometric parameters of slope and exposure were created based on isolines and elevation marks of the topographic base scale 1:100000. In the process of analyzing the model and geomorphological decoding of the arch-block mountains, the planned-altitude metric parameters of relief types with their characteristic forms and elements, morphometric properties with determining factors of formation and development of gravitational processes were established. High-mountain erosion-exaration-, denudation-erosion-; medium-mountain erosion-denudation-, denudation-erosion- and low-mountain denudation relief types are distinguished. For geomorphometric analysis and diagnostics of slopes, reference polygons characterizing the types of arch-block mountains relief, possessing certain geophysical properties and features were selected. To visualize each polygon, slope mapping-and-exposure was performed, as well as a satellite image was presented. As a result of the conducted research, a typical set of dangerous gravitational processes was identified for each type of relief, as well as their possible intensity, which can create risks of economic activity in mountainous areas. The results of the study can be used in design work for the modernization of the Baikal-Amur Mainline and the development of new mineral deposit

Research on the Design and Bidirectional Work Process of Metal Diaphragms in Small Double-Pulse Solid Rocket Motors

According to the requirements of the small double-pulse solid rocket motor, a compartmentalized isolation device has been designed. This device consists of a metal diaphragm and a support frame. An experimental study and numerical simulation were used to verify the bidirectional working process of the metal diaphragm during operation of the double-pulse motor. The results show that the pressure-bearing capacity of the metal diaphragm meets the requirements under the working conditions of pulse I without affecting pulse II, because the metal diaphragm can provide insulation and flame retardancy. The metal diaphragm can be cracked in the direction of the preset V-groove in a relatively short time under the working conditions of pulse II, which allows the gas to flow to the first pulse combustion chamber normally. This indicates that the metal diaphragm can meet the requirements of bidirectional working process in dual-pulse motors.

Copyist or Creative? The Emergence of the Woman Fashion Artist in Britain, 1880–1920

Abstract The period between 1880 and 1914 was a critical time for the redefinition of high fashion as a form of art, with couture garments displayed at international exhibitions and couturiers like Paul Poiret claiming the legal protection applied to artworks for his fashion designs. At the same time, a massive expansion in illustrated journals and catalogs selling mass-produced garments offered new possibilities for graphic artists, including women trained in the applied arts by public and private colleges. These trends intersected in the figure of the female “fashion artist,” who conceived new designs or presented them to the public—but did not stitch them. In some cases, this person was a designer working for a dressmaking firm or sample house, while others were copyists of existing garments. This article will analyze surviving documents produced by British women fashion artists; examine the life cycle of fashion artists, as revealed in census data; analyze the pathways for training and career development; and consider the ways in which fashion artists were discussed in women’s magazines, both as role models for employment and as fashion mediators.

Les filles de Méliès: l’exception culturelle, analogue aesthetics and women filmmakers of le cinéma-monde

ABSTRACT This article examines transnational francophone films from writer-directors Marjane Satrapi and Chloé Mazlo, filmmakers who show how the politics of l’exception culturelle [the cultural exception] have made French cinema a multiply exceptional force in world cinema. The analogue effects in Poulet aux prunes/Chicken with Plums (2011) and Sous le ciel d’Alice/Skies of Lebanon (2020) mark an aesthetic resistance to the homogenising force of digital photorealism while also reflecting an approach to filmmaking pioneered by Georges Méliès, particularly his ground-breaking work in set design and cinematography. As women filmmakers, their reliance on practical aesthetics to present stories set outside l’Hexagone (mainland France) represent the French commitment to the diversity of cinéma-monde. This article argues that these filmmakers and their films have benefitted from policies rooted in l’exception culturelle while expanding the sense of ‘exception’ in a French context to mean films directed by women, films featuring analogue effects and films that reflect transnational identities and cross-cultural collaboration. Both Poulet aux prunes and Sous le ciel d’Alice frame an expanded logic for l’exception culturelle that has shaped more than three decades of contemporary French cinema.
