Renovation of blocks of typical low-rise buildings 1940-1950 in Samara in the paradigm of contextual design

The prospects for the renovation of residential blocks of the 1940-1950s in the paradigm of contextual design are determined. For this purpose, the structure and morphology of neighborhoods was studied, the main types and characteristic features of the existing urban fabric were identified. An analysis was carried out of the quality of the existing environment of the territories, their provision with transport and social infrastructure. A judgment is given about the nature and specificity of renovation, taking into account the existing urban planning context, the historical memory of people, and the richness of the environment. The thesis about the historical value of typical low-rise buildings and the uniqueness of the urban morphology of the research object is substantiated. The boundaries of the renovation areas have been determined. A list of areas for proposed renovation is given. Principles for the renovation of built-up areas of the 1940-1950s have been developed, as well as models illustrating an operational approach to solving the problem.

Intentional and Responsible

Unintended consequences of technology are ubiquitous and often negative. Certain communities, the Amish for example, have minimized these consequences by understanding and agreeing upon the social values they seek to preserve, and by making technology choices based on these values. Although similar strategies are not widely implemented in Western society, technology developers should be intentional and responsible about the impact of their work. Existing design strategies that deal with values (e.g., contextual design) focus on adapting to business culture rather than preserving social values. This article proposes a new process model that focuses on articulating social values during the design phase as a method by which to evaluate the attributes of the system being developed, and discusses a planned experimental design intended to measure the effectiveness of this approach. By considering the relationship between design decisions and social values, this model may result in a design strategy that is both intentional and responsible.

Data-based equations for damage evaluation of reinforced concrete columns with square cross sections

This study aims to develop simple equations for assessing the damage of reinforced concrete (RC) columns subjected to seismic loading. A fiber element model in OpenSees, validated against experimental data, was used to generate a large dataset of 56548 data values for various RC columns. The Monte Carlo Hierarchical Adaptive Random Partitioning (MC-HARP) strategy was then applied to evaluate the sufficiency of the dataset and propose reliable equations for estimating the residual displacement ratio (RDR), damage index (DI), and residual curvature of RC columns under given displacement demands. A relationship between these parameters and the structural performance levels was also established. Residual displacement is a practical measure that can be observed in the field after an earthquake. The proposed equations facilitate the determination of the performance level of the structure after an earthquake event. The findings of this paper can also be used in designing new structures within a performance-based seismic design (PBSD) context.

Pareto Optimization of Analog Circuits Using Reinforcement Learning

Analog circuit optimization and design presents a unique set of challenges in the IC design process. Many applications require the designer to optimize for multiple competing objectives, which poses a crucial challenge. Motivated by these practical aspects, we propose a novel method to tackle multi-objective optimization for analog circuit design in continuous action spaces. In particular, we propose to (i) extrapolate current techniques in Multi-Objective Reinforcement Learning to continuous state and action spaces and (ii) provide for a dynamically tunable trained model to query user defined preferences in multi-objective optimization in the analog circuit design context.

The Role of Gastric Lipase and Pepsin in Lipid Digestion of a Powder Infant Formula Using a Simulated Neonatal Gastric System

This study has sought to determine the impact of interfacial dynamics on the in vitro lipid digestion of a commercial infant formula; in particular, the specific role of interfacial proteolysis on the subsequent rates of reaction of droplet lipolysis. A powder infant formula was used as the as a protein-stabilised emulsion substrate during simulated infant gastric digestion at different pH level 3.5, 4.5 and 5.5. The digestate was treated with a fungal lipase and porcine pepsin (used to analogue human gastric lipase and pepsin) respectively and in a combined action. The study found that for fungal lipase treated digestate, the rate and extent of lipolysis were observed to be maxim at pH 5.5, in accordance with the optimal pH activity of the lipase. Findings also indicated that the proteinaceous interface did not appear to act as a barrier to lipolysis, since treatment with lipase and pepsin did not result in any significant increase in extent of lipolysis. However, it was observed that surface proteolysis did lead to alteration of the structural fate of the enzyme during digestion when compared to when the emulsion was digested solely by lipase. Findings suggest that lipolysis under these conditions may be independent of the structural dynamics of the emulsion during digestion, as observed within the context of this study design.

Investigating the role of spatial thinking in children’s design ideation through an open-ended design-by-analogy challenge

Spatial thinking is ubiquitous in design. Design education across all age groups encompasses a range of spatially challenging activities, such as forming and modifying mental representations of ideas, and visualizing the scenarios of design prototypes being used. While extensive research has examined the cognitive processes of spatial thinking and their relationships to science, technology, engineering, and mathematics learning, there remains a knowledge gap regarding the specific spatial thinking processes needed for open-ended problems, which may differ from those assessed in close-ended, analytical spatial tasks. To address this gap, we used educational design-based research to develop a nature-inspired, design-by-analogy project and investigate the spatial thinking processes of young, novice designers. 16 children from an international school in the Netherlands participated in this five-week design project. Multimodal evidence from classroom recordings and children’s design works were triangulated to offer insight into the key spatial thinking processes involved in their creation of nature-inspired, analogy-based design prototypes. Our results revealed spatial thinking processes that might not align with those assessed in conventional spatial tests and may be unique to design or open-ended problem-solving. These processes include abstracting spatial features to infer form-function relationships, retrieving a range of relevant visual information from memory, developing multiple possible analogical matches based on spatial features and relationships, elaborating and iterating on the design concepts and representations to make creative and suitable solutions for the design challenge, as well as visualizing design prototypes in practical usage scenarios. By highlighting the nuanced differences between spatial thinking in open-ended, divergent thinking tasks and conventional spatial tasks that demand single correct solutions, our research contributes to a deeper understanding of how children utilize spatial thinking in design and open-ended problem-solving contexts. Furthermore, this case study offers practical implications for scaffolding children's analogical reasoning and nurturing their spatial thinking in design education.

An Indian perspective on interdisciplinary storylines and science practices in a socio-cultural context

ABSTRACT Context-based STEM learning has been proven to be useful as interdisciplinary storylines to regulate the flow and sequencing of lessons to obtain expected outcomes. This case study pilot project aims to contextualise scientific learning to local culture. Student groups sampled from two schools in distinct social backgrounds, reflected varied Indian population. Pre-service middle school science and social studies teachers conducted eight lessons as an interdisciplinary storyline with a few natural and social science concepts utilising an artefact representing the cultural history of India for seventh-graders. Data were collected through manually recording of students’ responses and products made during class activities; researchers’ observations and pre-service teachers’ feedback about finding solutions to the difficulties faced. In order to address three research questions about socio-cultural context in science-curriculum design, student adoption of 3D learning, and overcoming teachers’ challenges, a thematic analysis of data through the lens of five science practices and one crosscutting concept was performed. This study supported context-based STEM learning for the twenty-first century and strengthened cultural anchoring from an early stage implying the need for teacher professional development, curricular reform, and school infrastructure improvements to support policy implementation. Such researches may be extended to varied sociocultural contexts and discipline combinations to offer broader perspectives.

Subtle Sound Design: Designing for Experience Blend in a Historic House Museum

In this article, we present and discuss a user-study prototype, developed for the Bakkehuset historic house museum in Copenhagen. We examine how the prototype—a digital sound installation—can expand visitors’ experiences of the house and offer encounters with immaterial cultural heritage. Historic house museums often hold back on utilizing digital communication tools inside the houses, since a central purpose of this type of museum is to preserve an original environment. Digital communication tools, however, hold great potential for facilitating rich encounters with cultural heritage and in particular with the immaterial aspects of museum collections and their histories. In this article, we present our design steps and choices, aiming at subtly and seamlessly adding a digital dimension to a historic house. Based on qualitative interviews, we evaluate how the sound installation at Bakkehuset is sensed, interpreted, and used by visitors as part of their museum experience. In turn, we shed light on the historic house museum as a distinct design context for designing hybrid visitor experiences and point to the potentials of digital communication tools in this context.

Challenges Faced by University of Limpopo Learner Nurses during Psychiatry Clinical Exposure: A Qualitative Study.

Clinical exposure of learner nurses to psychiatric hospitals is a requirement by the South African Nursing Council. Clinical experience helps learner nurses build cognitive and affective skills, cultural acculturation, and professional identity. The clinical placement also aids nursing learner nurses in making decisions regarding future career paths. The goal of psychiatric nursing practice is to enhance mental and physical health and improve the patient's quality of life and rehabilitation. A qualitative research approach was followed, and a descriptive, explorative, and contextual design was used in this study to explore the challenges faced by University of Limpopo learner nurses during psychiatry clinical exposure. The population included learner nurses from level two to level four who registered for psychiatric nursing science practice. Convenience sampling was adopted. Semi-structured interviews were used to collect data, and the data were analyzed using the Tesch open coding method. Measures to ensure trustworthiness were adhered to, and ethical considerations were observed. The findings of this study indicated that learner nurses go through challenges and discomfort in the form of mental health care users, clinical environment matters, and the attitude of clinical staff in the hospital. Proper preparation of the learner nurses and clinical areas can assist in reducing the challenges that learner nurses go through.

The Impact of Golden Ratio Application on User Satisfaction: A Study on Horizontal Scrolling in User Interface (UI) Design

The utilization of the golden ratio scheme is well-established for enhancing aesthetic appeal and visual harmony in various design contexts. However, its application in user interface (UI) design, particularly concerning mobile screen elements, has been less explored. The potential benefits of incorporating the golden ratio into UI elements in mobile applications remain unclear, primarily due to a lack of comprehensive understanding. This study investigates the impact of implementing the golden ratio in UI design, including its influence on user satisfaction. A sample of 114 participants, comprising designers, participated in the study. Result: the simple linear regression analysis revealed a 7.5% coefficient, indicating a positive relationship between the integration of the golden ratio and heightened user satisfaction. These findings offer valuable insights for UI designers, especially for designing mobile applications requiring expanded space, such as catalog apps. Nevertheless, further research is necessary to explore the golden ratio’s application in UI design for devices with smaller screens, like smartwatches or digital cameras.

A formalized shared decision-making process with individualized decision aids for older patients referred for cardiac surgery.

Comprehension of risks, benefits and alternative treatment options is poor among patients referred for cardiac surgery interventions. We sought to explore the impact of a formalized shared decision-making (SDM) process on patient comprehension and decisional quality among older patients referred for cardiac surgery. We developed and evaluated a paper-based decision aid for cardiac surgery within the context of a prospective SDM design. Surgeons were trained in SDM through a Web-based program. We acted as decisional coaches, going through the decision aids with the patients and their families, and remaining available for consultation. Patients (aged ≥ 65 yr) undergoing isolated valve, coronary artery bypass graft (CABG) or CABG and valve surgery were eligible. Participants in the non-SDM phase followed standard care. Participants in the SDM group received a decision aid following cardiac catheterization, populated with individualized risk assessment, personal profile and comorbidity status. Both groups were assessed before surgery on comprehension, decisional conflict, decisional quality, anxiety and depression. We included 98 patients in the SDM group and 97 in the non-SDM group. Patients who received decision aids through a formalized SDM approach scored higher in comprehension (median 15.0, interquartile range [IQR] 12.0-18.0) than those who did not (median 9.0, IQR 7.0-12.0, p < 0.001). Decisional quality was greater in the SDM group (median 82.0, IQR 73.0-91.0) than in the non-SDM group (median 76.0, IQR 62.0-82.0, p < 0.05). Decisional conflict scores were lower in the SDM group (mean 1.76, standard deviation [SD] 1.14) than in the non-SDM group (mean 5.26, SD 1.02, p < 0.05). Anxiety and depression scores showed no significant difference between groups. Institution of a formalized SDM process including individualized decision aids improved comprehension of risks, benefits and alternatives to cardiac surgery, as well as decisional quality, and did not result in increased levels of anxiety.

Concrete and Development: Context-driven Formwork Design for Scalable, Accessible and Low-carbon Concrete Structures

Society is building at an unprecedented rate: building stock will need to double by 2060 (UNEP 2021), adding over 230 billion m2 (24.7 billion ft.2) of floor area in new construction, equivalent to a new Paris every week (Abergel et al. 2017). Most of this construction will occur in Less Economically Developed Countries (LEDCs). This article advocates using materially efficient design methods that enable sustainable development through scalable, low-cost, low-carbon concrete structural systems for LEDC construction. This article presents a generalized framework for evaluating contextual design and fabrication methods before demonstrating its use by evaluating several lab-scale structurally optimized prototypes. It begins with a discussion of the motivating factors for low-carbon concrete construction in LEDCs.

The Transformation of Traditional Chinese Painting Elements in Modern Design Contexts

Abstract To ensure the effective preservation and evolution of traditional painting art, it is imperative to integrate contemporary art design concepts and methodologies. This paper focuses on the reconstruction of traditional Chinese painting elements, distilling and adapting its pattern, ink, and calligraphy components into a modern design framework. Specifically, the features of the pattern elements are identified and transformed using a feature point extraction algorithm combined with K-Means clustering. For ink and calligraphy elements, a fusion of self-attention mechanisms and Generative Adversarial Networks (GANs) facilitates the stylistic migration and conversion of these elements through the construction of distinct discriminators. Subsequent evaluation of the transformed painting elements utilized Importance-Performance Analysis (IPA) within a contemporary design context, aiming to assess the practical value of traditional painting elements in modern design. The findings indicate that the clarity of information (C1) and its accuracy and efficacy (C3) in the context of contemporary design achieved importance scores exceeding 3.6. Furthermore, the satisfaction scores for modeling (C10), color (C11), and imagery (C12) each surpassed 3.5, denoting a high level of satisfaction in the IPA of their conversion. The study enriches traditional artistic methods and conceptualizations, thereby enhancing their cultural depth and significance.

XMKR: Explainable manufacturing knowledge recommendation for collaborative design with graph embedding learning

Design for manufacturability is crucial to ensure high-quality products. It fully considers manufacturing-related factors in a collaborative design manner. However, since manufacturing knowledge is unstructured and hard to reuse, designers mainly depend on frequent design iterations to meet complex manufacturing constraints. Such insufficient design-manufacturing collaboration is not conducive to design efficiency improvement. To alleviate the problem, this paper proposes a novel graph embedding-based approach of Explainable Manufacturing Knowledge Recommendation (XMKR) for collaborative product design, which could achieve designer-oriented manufacturing knowledge reuse to avoid design errors proactively and minimize excessive iterations. Firstly, a graph embedding model based on the graph neural network (MKGE-GNN) is proposed to learn implicit semantic information of manufacturing knowledge. Secondly, with MKGE-GNN learning results, the potential manufacturing knowledge preferences of designers are identified in the design context graph by Personalized PageRank to achieve context-aware explainable manufacturing knowledge recommendation. Finally, a car body collaborative design case is conducted to validate the efficacy of the proposed approach, which not only provides accurate manufacturing knowledge in designers’ decision-making, but also enhances designers’ cognitions for manufacturability in the dynamic design context.

BIM design coordination: conflict analysis and construction simulation

The Building Information Modelling (BIM) methodology has been adopted in the construction industry, supporting the development of projects. Its implementation has improved the collaboration and integration in the design context, increasing the accuracy of the project preparation and the decreasing additional costs and delays of the construction work. The main objective of the present research is to provide an overview of the state of the art of BIM applications, namely, concerning the construction planning. For that, the generation of a BIM 3D model, involving the disciplines of architecture, structures and water supply system was performed. After, over the model a conflict analysis was applied, in order to verify the consistency of all the disciplines, when linked together. In order to obtain a visual simulation of the construction process, the correspondent 4D BIM model was also generated. Along the development of the study, several BIM software were applied over a case study. The main remarks of the capacities of the software, as well as the benefits and limitations verified were identified.

Integrating clinical and biochemical markers: a novel nomogram for predicting lacunes in cerebral small vessel disease.

Lacunes, a characteristic feature of cerebral small vessel disease (CSVD), are critical public health concerns, especially in the aging population. Traditional neuroimaging techniques often fall short in early lacune detection, prompting the need for more precise predictive models. In this retrospective study, 587 patients from the Neurology Department of the Affiliated Hospital of Hebei University who underwent cranial MRI were assessed. A nomogram for predicting lacune incidence was developed using LASSO regression and binary logistic regression analysis for variable selection. The nomogram's performance was quantitatively assessed using AUC-ROC, calibration plots, and decision curve analysis (DCA) in both training (n = 412) and testing (n = 175) cohorts. Independent predictors identified included age, gender, history of stroke, carotid atherosclerosis, hypertension, creatinine, and homocysteine levels. The nomogram showed an AUC-ROC of 0.814 (95% CI: 0.791-0.870) for the training set and 0.805 (95% CI: 0.782-0.843) for the testing set. Calibration and DCA corroborated the model's clinical value. This study introduces a clinically useful nomogram, derived from binary logistic regression, that significantly enhances the prediction of lacunes in patients undergoing brain MRI for various indications, potentially advancing early diagnosis and intervention. While promising, its retrospective design and single-center context are limitations that warrant further research, including multi-center validation.

Rôle des routines et de leurs artefacts dans l’articulation entre standardisation et flexibilité : proposition d’un cadre conceptuel intégrateur

This article aims to introduce a conceptual framework to account for the interplay between standardization and flexibility within organizational contexts. This framework focuses on this interplay through the perspective of organizational routines and their artifacts. It allows to make connections between various contributions that were so far relatively independent. We stress how the concepts of inscription and affordance are useful to consider how artifacts are intricately woven into the social fabric of their design and usage contexts, without neglecting their material forms.
