Abstract

The healing effect of the aroma treated fabrics with lavender and lemon aromas was investigated by assessing the autonomic nervous responses of human body. For this cause Lemon and lavender microcapsules were coated on a cotton fabric using a water-based acrylic binder, respectively. And the study created a total of four aroma treated fabrics at a concentration of 2% and 5% respectively. Electrocardiogram(ECG), skin conductance, and Blood flow, of ten participants were measured for 30 sec at a stable condition, at a stress status (working memory task), and at a stimulation status (after rubbing aroma treated fabrics). Subjective sensibilities of the aromas were also evaluated. With regard to the responses of the autonomic nervous system, in order to understand how the values gained after the normalization process would cause different physiological signals between the stable state and the aroma-stimulated state as well as between the stress state and the aroma-stimulated state, the study conducted a non-parametric test, friedman test as well and analyzed tendencies. LF/HF turned out to be significantly different to the stress state, and according to the results of the post-hoc comparison, lemon 5% presented statistically significant differences among the lavender 2%, lavender5%, lemon2%. Lemon 5% stimuli increased stress but stimuli consisting of the lavender 2%, the lavender 5% and the lemon 2% decreased stress because of a psychological rest. And the stimuli of the lavender 2%, the lavender 5%, the lemon 2% presented a healing effect in this research.

본 연구는 라벤더 향과 레몬 향을 포함하는 방향성 의류소재에 힐링효과가 있는지 알아보고자 신체 반응인 자율신경계 반응을 평가하였다. 이를 위해 라벤더와 레몬향의 마이크로캡슐과 수성 아크릴 바인더를 사용하여 면직물에 코팅처리 하여 각각 2%, 5%의 농도로 처리 된 라벤더와 레몬향의 방향성 의류소재 총 4종을 만들었다. 심전도, 피부전도수준, 혈류량의 실험 참여자는 10명 이었으며, 안정 상태에서 30초, 스트레스 상태 (working memory task) 30초, 향 자극 상태(방향성 섬유를 비벼 향을 나게 한 후) 30초를 측정하였다. 그리고 주관적 감성 평가도 함께 실시하였다. 데이터를 분석하기 위해 표준화를 해주었으며, 표준화 값에 대하여 안정 상태와 자극 상태의 생리신호 차이와, 스트레스 상태와 자극 상태의 생리신호 차이를 알아보기 위해 비모수검정 Friedman 검증을 통해 그 경향을 분석 하였다. 자율신경 발란스 지수(LF/HF)는 스트레스 유발 후 향 자극 상태와 유의한 차이가 있어 사후검증 하였다. 그 결과 레몬 5%의 향 자극은 라벤더 2%, 라벤더 5%, 레몬 2%의 향 자극과 유의한 차이가 있었다. 스트레스 유발 후 레몬 5%의 향 자극은 스트레스를 증가 시켰으나 라벤더 2%, 라벤더 5%, 레몬 2%의 향 자극은 심리적 안정을 유발하여 스트레스를 감소시켰으며 본 논문에서 힐링효과를 나타냈다.
