초록
본 연구는 자율신경계 반응을 기반으로 계곡, 임도, 그리고 도시의 경관감상이 감성상태의 변화에 미치는 영향을 확인하는 것을 그 목적으로 하였다. 신체 건강한 대학생 10명 (남 4명, 여 6명, 평균나이: 24±2.9) 을 대상으로 계곡, 임도, 그리고 도시의 경관을 감상하는 동안의 심전도(ECG, Electrocardiogram)와 혈압을측정하였고 심리상태 평가를 위해 POMS(Profile of Mood States)와 SD(Semantic Differential Method)법을이용한 주관설문을 실시하였다. 측정된 심전도 신호를 기반으로 HRV(Heart Rate Variability) 분석을 통해 교감 및 부교감 신경계의 활성도를 평가하였고 HRP(Heart Rhythm Pattern) 분석을 기반으로 감성상태를 정량적으로 평가하였다. 연구 결과, 계곡과 임도의 자연경관을 감상하는 것이 도시에 비해 자율신경계 균형과 혈압을 안정시키는 효과가 있는 것으로 확인되었으며, 심리 상태를 안정시키고 긍정적이고 편안한 감성을 유도하는것으로 확인되었다. 또한, 자연경관 중에서는 계곡이 임도에 비해 생리 반응과 심리상태를 안정시키는 효과가더 큰 것으로 나타났다. 본 연구는 산림치유에 관한 정량적 데이터 축적의 관점과 감성을 정량적으로 평가하는방법을 통해, 산림치유가 신체적 건강(Physical Care)뿐만 아니라, 심리적 안정과 긍정적인 감성을 유발하는 멘탈케어(Mental Care)까지 그 확장가능성을 확인하는데 그 의의가 있다. 또한, 산림의 다양한 요소에 따른 정량화를 통해 감성 서비스 제공이 가능할 것으로 기대된다.
Abstract
The purpose of this study was to determine the viewing of valley, forest road, and city affected by emotional state based on ANS(Autonomic Nervous System). Ten volunteers(6 females, age: 24±2.9) participated in this research, and Blood pressure, ECG(Electrocardiogram) were measured during the viewing of natural landscape and city. In order to assess a mental state, POMS(Profile of Mood States) and SD(Semantic Differential Method) were used. Activity of sympathetic and parasympathetic nervous system was evaluated using by HRV(Heart Rate Variability), and emotional state was assessed based on HRP(Heart Rhythm Pattern). In this result, the autonomic balance and blood pressure were a stable state in the viewing of natural landscape(valley & forest road) rather than the city. The emotional state was brought positive-relaxation domain in valley and forest road rather than city. In the result of comparison between valley and forest road, the valley impacted greatly on stable state. This result is meaningful in view of data accumulation, for forest healing. And the possibility for forest healing is confirmed that it is available not only physical care but also mental care with quantitative evaluation of emotional state. Also, emotion service is expected to provide forest healing industry with emotional quantification of various forest factors.
