Abstract

This study selects two linear parks representing each culture and reveals the differences between them using a visitor survey as small data and social media analytics as big data based on the three components of the model of landscape perception. The 606 in Chicago, U.S., and the Gyeongchun Line in Seoul, Korea, are representative parks built on railroads. A total of 505 surveys were collected from these parks. The responses were analyzed using descriptive statistics, principal component analysis, and linear regression. Also, more than 20,000 tweets which mentioned two linear parks respectively were collected. By using those tweets, the authors conducted the clustering analysis and draw the bigram network diagram for identifying and comparing the placeness of each park. The result suggests that more diverse design concept links to less diversity in behavior; that half of the park users use the park as a shortcut; and that same physical exercise provides different benefits depending on the park. Social media analysis showed the 606 is more closely related to the neighborhoods rather than the Gyeongchun Line Forest. The Gyeongchun Line Forest was a more event-related place than the 606.

이 연구는 경관 인식 모델의 세 가지 요소(활동, 물리적 환경, 이용자)를 기본으로 하는 스몰데이터인 설문조사와 빅데이터인 소셜미디어 분석을 통해 문화가 다른 두 지역(미국, 한국)의 선형 공원 두 곳을 분석하고자 한다. 소셜 미디어의 사용이 증가하고 경관을 보는 새로운 매체로 부상했음에도 불구하고, 현재 소셜 미디어를 활용한 공원 연구는 제한적이다. 이에 본 연구는 소셜 미디어 분석과 설문 조사를 동시에 활용해서 비교함으로써 설문 조사가 갖는 한계를 보완함과 동시에 소셜 미디어 분석의 제한점을 보완하고자 한다. 미국 시카고의 606 트레일와 한국 서울의 경춘선 숲길은 버려진 길에 조성된 공원이다. 이 두 곳을 대상으로 총 505부의 설문조사를 시행했고, 그 결과는 통계 분석, 주성분 분석, 회귀 분석을 활용해서 분석하였다. 또한 각 선형 공원을 언급한 트위터를 총 20,000건 이상 수집했다. 이 트위터를 대상으로 군집 분석, 바이그램 네트워크 분석 등을 통해 각 공원이 갖는 장소적 특성 및 물리적 환경을 분석했다. 연구 결과는 공원 디자인이 다양해질수록 행동은 단순화 된다는 것을 발견할 수 있었다. 공원 이용자들의 절반은 선형 공원을 최종 목적지까지 도달하는 지름길로 이용했고, 공원의 특징에 따라 다양한 활동과 혜택을 확인할 수 있었다. 소셜 미디어 분석 결과, 606트레일은 경춘선 숲길 보다 주민들과 더욱 밀접한 관계를 갖고 있다는 것을 확인했다. 또한 경춘선은 606트레일보다 공원 내 이벤트와 연관이 깊음을 발견할 수 있었다.
