The fragrance has a great influence on consumers' cognition, emotional response, attitude, memory, and behavior since the human sense of fragrance is physically and neurologically closer to the hippocampus of the brain. The fragrance materials are exposed to humans ranging from skin interaction to inhalation. We have lots of stories and literature on the usage of fragrance in everyday life in Korea from the Dangun myth to present K-beauty cosmetics. In Korean history, such archives as Dong-Eui-Bo-Gam and Gyu-Gak-Chong-Seo at Joseon Dynasty clearly recorded the application of many weeds for the manufacture of various fragrance products. In recent times, fragrances in weeds have been being applied to touch the consumer's feelings. The present mini-review is an attempt to introduce and discuss fragrant weeds in the archives and in science journals, effects of fragrant weeds on the human electroencephalographic activity, and effects of fragrance on the behavior of consumers. This review could be useful for the development of natural cosmetic and perfumery products from fragrant weeds.

This study investigated natural aroma fragrance on the fashion image of Galchon, a traditional natural dyeing textile made with immature persimmon from the Jeju area, Korea. Nine fabric pairs consisting of differently colored cotton and silk Galchon with various tones and fabric types were used for subjective evaluation. Thirty five female college students evaluated the specimens using a 7-point scale questionnaire for fashion image-related adjectives. A specimen with three different presentation types that included fabric without fragrance (FO), fabric with citrus fragrance, and fabric with chamaecyparis (FCP) were randomly provided to a subject. As a result, color variables of Galchon were found to be the primary influence on fashion images for both cotton and silk Galchon that showed interaction effects with presentation types. The citrus fragrance increased the feeling of 'Active' while chamaecyparis tended to contribute to a stronger perception of 'Elegance' for cotton Galchon. Finally, these results were used to develop prediction models for fashion images of Galchon that employed color variables and presentation types.

This study investigated EEG signal, subjective fragrance sensation, and the preference of differently colored cotton knit treated with Citrus unshiu oil containing microcapsules as well as examined their relationships for providing regression models on subjective fragrance preference. Color variables combining 2-level hue (Yellow and Green) and 3-level tone (strong, pale, and grayish) were applied by dyeing prior to microcapsule treatment. We invited 28 female college students aged 20's for EEG signal experiments and subjective fragrance sensations with fragrant knit by rubbing. EEG signals at $mid-{\alpha}$, $fast-{\alpha}$, and $low-{\beta}$ showed significant differences depending on color; Green had more relative power values and grayish tone did more at $low-{\beta}$. Even though subjective sensation showed no significant differences depending on color, some of them such as Fresh, Comfort, and Natural showed significant correlations with EEG signal at $low-{\beta}$, which means that the fragrance sensations of Citrus unshiu fragrance are concerned with attention and alertness for Koreans. Fragrance preference was regressed significantly using some EEG signals and subjective sensation. The results could be utilized to value up fragrant textiles by Citrus unshiu oil.

This study was carried out to find the effects of aromatherapy using natural fragrance on reducing stress and improving job satisfaction of transportation workers in the taxi industry. A total of 120 workers were divided into the experimental group and the control group according to the inhalation of the fragrance and tested for 2 weeks. After 2 weeks, the difference of emotional change, stress analysis, and evaluation of job satisfaction according to aromatherapy were compared between the two groups. The result showed that the experimental group had a higher interest in scent products than the control group and that they wanted to encounter a lot of real scents, indicating that aromatherapy caused positive interest in general scent likability. In addition, the experimental group said that the inhalation of fragrance would refresh the feeling of the passengers in the vehicle and smoothly communicate with the passengers. Especially, it showed a significant difference between the two groups in terms of tension relief, pleasure and good mood by inhalation of fragrance, indicating the positive effect on job satisfaction.

The essential oil of Nardostachys jatamansi (Valerianaceae), which has been used for a long time in aroma therapy, was investigated after inhalation or oral administration for its analgesic effect, anticonvulsant action, hypnotic effect and in vitro inhibitory activity on monoamine oxidase. This fragrance oil showed a significant analgesic effect in the phenylquinone-induced .writhing test, suppressed the convulsion induced by pentylenetetrazole and lengthened the pentobarbital-induced sleeping time in a time-dependent manner after fragrance inhalation or dose-independently by oral administration. Its inhibitory activity on monoamine oxidase was remarkable, showing $49.4\%$ inhibition at a concentration of 5.0 mg/ml. Six new terpenes with seven known compounds were detected by our GC-MS analytical conditions used. As a result, the essential oil fragrance of Nardostachys jatamansi would be clinically useful for a sedative by either inhalation or oral administration.

천연가스 중의 부취제 농도를 분석하기 위한 기체 크로마토그래피 방법에 대하여 연구하였다. TBM(tertiarybutylmercaptan) 및 THT(tetrahydrothiophene)를 포함한 8종의 부취제를 OV-101 컬럼상에서 거의 완전히 분리하였다. 수소 유속, 공기 유속 및 검출기 온도와 같이 FPD의 응답에 영향을 미치는 몇 가지 상호 관련된 파라미터들의 최적 조건을 구하였다. TBM과 THT의 검정곡선을 투과한 장치를 이용하여 작성하였다. 이러한 분석방법을 천연가스 공급관 내의 혼합 부취제인 TBM과 THT를 정량하는 데 적용하였다. 부취수준과 부취제 농도와의 상관관계를 구하기 위한 냄새 측정기의 유용성에 대하여 알아보았다.

본 연구는 화기 부위에 따른 국산 심비디움 '샐빛'과 '미단'의 향기 특성을 분석하고자 수행하였다. 시험 재료로 국립원예특작과학원 화훼과 시험포장에서 재배한 만개한 꽃을 꽃잎, 꽃받침, 순판, 컬럼으로 나누어 GC 기반 전자코를 통해 향기 패턴과 주요 향기 성분을 분석하였다. 그 결과, 두 품종 모두 화기 부위에 따라 PCA와 DFA plot에서 뚜렷한 향기 패턴 차이를 보였고, 각 화기 부위별 무취공기 대조구 간의 기하학적 거리는 꽃받침이 가장 멀었으며, 향기패턴 식별지수(PDI) 또한 대조구와 꽃받침 사이에서 가장 높게 나타났다. 주요 향기 성분 중 nootkatone 등의 성분은 '샐빛'과 '미단' 두 품종 모두네 개의 화기조직에서 공통적으로 검출된 반면, '미단'에서만 검출되는 decane과 같이 일부 성분은 특정 품종이나 화기 부위에서만 특이적으로 발견되었다. 따라서 본 연구결과는 품종과 화기 부위에 따른 향기패턴과 주요 향기 성분을 확인함으로써 향기 산업에 필요한 효율적인 원료 선택과 국산 품종의 이용 확대를 위해 유용한 정보를 제공할 것으로 기대된다. 특히 최근 인공 가향제에 대한 부정적 인식과 천연 향기 원료에 대한 수요가 증가하는 점을 감안했을 때, 앞으로도 지속적인 유향성 난 품종 육성과 이를 산업적으로 활용하기 위한 향기 연구가 필요할 것으로 생각된다.

Products containing any one or more of 26 fragrance allergens likely to cause contact allergies, are required under the 2008 domestic cosmetic law to be labeled when their concentrations exceed a certain range. This study focuses on the comparison and development of analytical methods based on headspace-solid phase micro extraction (HS-SPME) and liquid-liquid extraction (LLE) methods followed by GC-MS/MS for 24 of the fragrance allergens excepting for two natural materials in water samples. Using the developed HS-SPME method, 15 of the 24 fragrance allergens were analyzed and 9 compounds which have relatively low $logK_{OW}$ values (below about 2.5) were not extracted, and the correlation coefficient ($r^2$) of the calibration curve for quantification showed linearity of 0.9969 or more, and the method detection limits (MDL) and the limits of quantification (LOQ) were $0.078{\sim}0.582{\mu}g/L$ and $0.261{\sim}1.940{\mu}g/L$, respectively. In the case of using the optimized LLE method, all 24 fragrance allergens were analyzed, and the correlation coefficient ($r^2$) of the calibration curve for quantification showed linearity of 0.9957 or more, MDL and LOQ were $0.020{\sim}0.138{\mu}g/L$ and $0.065{\sim}0.440{\mu}g/L$, respectively.
