Urban parks play a crucial role in enhancing the social interactions of older adults. However, despite the broad recognition of urban parks’ benefits, there is a notable gap in research focusing on their role in promoting social interactions, particularly in Asia. This study explores the effects of personal, social, and physical factors and park use patterns on older adults’ social interactions. Survey data from 589 older adults aged 50 years or older were collected through face-to-face and online questionnaires and were analyzed using a hierarchical multiple regression model. The results showed that personal factors, social factors, physical factors, and park use patterns explained 10.8%, 8.2%, 9.4%, and 2.3% of the total variance in park social interactions, respectively. Key factors like gender, health status, social cohesion, features, conditions, accessibility, and park use patterns were found to significantly influence these interactions. This study provides empirical evidence to support the important role of urban parks in facilitating social interactions among older adults and contributes to a deeper understanding of the complex factors affecting these interactions. To meet the needs of older adults and maximize the social health benefits, these prominent factors should be emphasized in policy development and interventions, integrating older adults’ perceptions and personal experiences.

Resilient design, as a strategy to address various disruptions and pressures, remains poorly understood among the public, which hinders its effectiveness. This study aims to explore how physical elements in urban form, environmental stimuli, and individual attributes influence public perception of resilient design characteristics. A video questionnaire survey was conducted to investigate these perceptions. Results indicate that physical elements—such as road signs, social service facilities, road infrastructure, accessibility to the center, accessible green spaces, diversified activity areas, and disability facilities—negatively impact public perception of resilient design. Conversely, environmental stimuli, including fast/slow, qualitative/quantitative, and short-term changes, positively influence these perceptions. Additionally, the findings reveal that older individuals, those with lower levels of education, and individuals who have had contact with the area for less than three years exhibit weaker perceptions of resilient design characteristics. The study proposes strategies for optimizing resilient design from the perspectives of physical elements and environmental stimuli, while also recommending that future research focus on groups with limited perceptions of resilient design characteristics.
