In contemporary society, a notable trend of diminishing family sizes has led to an increasing number of elderly individuals living in solitude, often facing the end of life alone. This phenomenon underscores a critical challenge: addressing the pervasive loneliness experienced by many seniors. In response to this pressing issue, the concept of “cross-generational co-living” emerges as a potential solution. By exploring and implementing cross-generational co-living models, this research contributes to the development of more inclusive, supportive, and adaptable environments. The investigation involved an extensive field study and comprehensive data analysis of twenty-four instances of cross-generational co-living spaces in China and Italy. This analysis utilized space syntax as a fundamental theoretical framework, incorporating convex graphical topological relationship extraction and visibility graph analysis models. The outcomes of the study indicate that the configuration of cross-generational co-living spaces include spatial form, type, location, and the proportion of areas. Spaces arranged in a cluster form are most effective in promoting mutual communication. Spatial types and locations characterized by elevated integration values demonstrate a heightened potential for cross-generational communication. Space possessing a higher integration value typically correlates with a reduced ratio of area discreteness. These findings are instrumental in understanding how cultural and societal variances shape the design and utilization of cross-generational co-living spaces. Consequently, this study provides valuable guidelines for improving environments that are essential for advancing the principles of age-friendly design, which aims to enhance the quality of life for the elderly and foster a more harmonious and interconnected society across all generations.

Communities worldwide are increasingly required to support populations spanning multiple generations while maintaining social cohesion in the context of rapid demographic ageing and urban transformation. Although frameworks for age-friendly or inclusive environments have gained international traction, existing evaluation methods seldom integrate the environmental qualities necessary for all-age-friendliness with the spatial and social conditions that enable cross-generational interaction. This study addresses this gap by developing a dual-lens evaluation framework that quantifies both fundamental environmental attributes and the interaction potential embedded within community spaces. Grounded in field investigations, spatial analysis, expert consultation, and user surveys, the study establishes a hierarchical indicator system comprising nineteen prerequisite indicators and sixteen enhancement indicators across five dimensions: site accessibility, spatial integration, environmental comfort, safety and health, and participation and inclusion. To operationalize the framework, a combined Fuzzy Analytic Hierarchy Process and multi-objective optimization model was employed, enabling the representation of interdependencies between essential conditions and value-enhancing features. Application of the framework to 24 community cases in Shanghai and Florence reveals both shared structural patterns and distinctive cultural influences: Shanghai demonstrates strengths in walkability and health-supportive infrastructure, whereas Florence excels in natural contact and environmentally integrated spatial typologies. The findings underscore the necessity of balanced environmental performance for achieving high-quality, all-age-friendly community spaces with strong cross-generational engagement potential. The proposed framework provides a replicable and analytically rigorous tool for environmental and social impact assessment, offering guidance for planners, policymakers, and designers seeking to promote inclusive, resilient, and socially cohesive community environments.

Knowledge of the relationship between pregnancy and oral health is a public health issue. The aim of this study was to assess the knowledge, attitudes and practices of pregnant women regarding oral health in the University Hospital Centers (UHC) of Ouagadougou in 2023. This was a descriptive cross-sectional study from July to September 2023. Data were collected prospectively, and knowledge, attitude and practice scores were generated. A total of 400 pregnant women were included. The [25-34] age group was the most represented at 54%, and 56.3% of women were in their 3rd trimester of pregnancy. The majority had a secondary level school and didn’t have a treating dentist. More than half (51.2%) of the respondents had poor overall knowledge of the relationship between oral health and pregnancy, 76.3% had poor attitudes and 79.5% poor practices, resulting in a poor overall KAP level for their oral health (60.5%). There was a significant variation in KAP level according to level of education (p= 0.015) and according to the information received on oral health and its implications for pregnancy (p = 0.028). Pregnant women's knowledge, attitudes and practices regarding their oral health are inadequate. Most women were unaware of the potential consequences of oral health neglect on pregnancy and their unborn child. Efforts must be made to educate them about oral health, with a focus on prevention.

Urban parks in city centers are often assessed by residential proximity, but visits in districts with mixed land uses also occur between work, shopping, services, and other daily activities. A nearby park may remain difficult to use when its entrances and internal paths do not align with the routes people take to reach it. This study presents Park-BIND (Park Boundary-Opening Identification and Network-Based Decision Model). It connects the activities before and after a park visit with complete walking routes, candidate feasibility, exhaustive optimization of opening sets, and space syntax analysis. Applied to two parks in the central area of Shanghai, the model evaluated and reviewed entrances and opening options suited to each site. Minimum opening sets designed to achieve 80% of the feasible route benefit (S80) captured 85.40% in Xujiahui Park and 82.42% in Xiangyang Park. High overall efficiency did not ensure balanced benefits. Balanced solutions raised the activity context receiving the least benefit above 90% of its feasible benefit in both parks. The opening scenarios also changed Integration, Choice concentration, and exposure to structurally important paths. These indicators describe potential movement patterns, not observed pedestrian flows or congestion. The findings support a phased strategy: begin with a small set of feasible and effective connections, add openings where needed to serve activity contexts more evenly, and reserve options with higher benefits or conditional feasibility for later action. Park access should therefore connect routes from city streets through public entrances to usable paths inside the park, rather than rely on proximity or entrance numbers alone.

The purposes of this study were to develop the design of virtual reality content using eyes and to investigate the usability of the virtual reality content for nonverbal students with severe disabilities. A 360-degree video in which a narrator introduces scientific activities (momentum, earthquake, gravity, robot dance) and experiences them at Chungnam Science Education Center was produced. Next, the virtual reality content for the video were designed for users to manipulate image buttons with their eyes so that users can select and experience images. Users can select and view images of scientific activity by staring and blinking using the HTC-VIVE Pro Eye, which combines eye tracking technology. The virtual reality content using eyes were designed and developed in accordance with the guidelines for supporting self-determination of students with severe disabilities. In order to investigate the usability of the VR content, 37 special education teachers who had special teacher certificates and had experience in teaching students with severe disabilities answered questions after using the VR content. The teachers evaluated as "neutral" in some usability evaluation categories (e.g., Self-determination, Ease of manipulation, Ease of Understanding, Effectiveness, Efficiency of class preparation, Efficiency in teaching, Appropriateness of content organization). When developing VR contents for students with severe disabilities, developers can design visual images in order for students with severe disabilities to understand easily and establish user interface in users’ eye conditions and operational capabilities. VR contents can be designed in relation to subject areas so that teachers can use them as educational materials.
