Assessment of the Gastrointestinal System II: Health Perception Pattern01:29

Assessment of the Gastrointestinal System II: Health Perception Pattern

162
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Area of Science:

  • Urban planning
  • Environmental psychology
  • Gerontology

Background:

  • Global population aging necessitates understanding elderly safety in urban public spaces.
  • Pocket parks are crucial for older adults' well-being and social interaction.
  • Perceptions of safety are influenced by the built and natural environment.

Purpose of the Study:

  • To identify visual elements in pocket parks that impact elderly safety perceptions.
  • To analyze the relationship between park design and older adults' sense of security.
  • To provide data-driven recommendations for designing inclusive urban green spaces.

Main Methods:

  • Image semantic segmentation of panoramic images from 29 pocket parks.
  • Combined manual scoring with deep learning for dataset creation.
  • Analysis using LightGBM and SHAP tools on 497 images.

Main Results:

  • Elderly safety perceptions were generally positive but varied across parks.
  • Seven key visual elements identified: pedestrian area, car, wall, person, billboard, parterre, and vegetation.
  • Vegetation significantly enhanced elderly environmental safety perceptions.

Conclusions:

  • Visual elements in pocket parks play a critical role in shaping elderly safety perceptions.
  • Park planners can leverage these findings to create more secure and inclusive green spaces for seniors.
  • The study offers practical guidance for enhancing urban environments for an aging population.
