스트리트뷰를 이용한 녹색환경과 사회 경제 변수의 인지 능력에 대한 상관관계 연구(은평구 코호트를 대상으로)

Abstract

Using Street-view this study measured the green index within a 500-meter radius of the residences of a cohort visiting Severance Hospital from Eunpyeung-gu. We examined the association of the green index and other individual factors(gender, age, income, and education) with cognitive ability. We found that neither the green index obtained from Street-view nor the EVI from satellite imagery showed a significant association with cognitive health. Instead, age, gender, and education level were revealed affecting cognitive health. As age decreased, being female, and having a higher education level were associated with better cognitive health. This suggests that individual factors are more closely related to cognitive ability than neighborhood factors such as the green index. However, to assess cognitive ability more objectively, alternative measurement methods such as brain imaging might be necessary. Additionally, this study solely focused on Eunpyeong-gu which exhibited a small variation in street view green indices. Further research should consider expanding the study area and adding various independent variables.
