  • 문헌에 따르면, 천연 추출물 또는 천연 에센셜 오일을 포함한 화장품 향의 흡입으로 뇌파 변화가 유도된다는 사례가 보고되어 있다. Angelica gigas (AG)와 Cnidium officinale (CO)는 건강을 개선하는 전통 약재로 동아시아 국가에서 널리 사용되고 있으나, 이들의 향을 흡입하여 뇌파(EEG)기록을 통해 뇌 활동 변화를 평가한 이전 보고는 없었다. 본 연구에서는, Artemisia princeps var. orientalis (Compositae), AG, and CO와 같은 천연 약초 추출물의 향을 흡입하고 후각 자극으로 감정적인 상태 변화가 야기되는지에 대한 평가를 하였으며, 20 ~ 30 세 시험대상자를 대상으로 천연 약초 추출물의 향을 흡입하기 전과 후에 뇌 활동을 EEG기록을 통해 확인하였다. 또한 향을 흡입하는 동안 자율신경계 변화는 심전도(ECG) 기록을 통해 심장의 전기적 활동을 관찰하였다. 시험 결과, 양성 대조군인 라벤더를 포함하여 Compositae, AG, CO 추출물의 향을 맡으면 뇌의 전반 영역에서 뇌파의 relative alpha power 와 alpha/beta ratio가 크게 증가하는 결과를 나타냈다. ECG 기록은 Compositae 향의 흡입이 low-frequency/high-frequency 비율을 유의미한 수준으로 감소시켰다. 결론적으로 전통 약초 추출물 향의 흡입은 뇌파와 자율신경계 변화가 유도하여 감성적 편안함과 심리적 안정감에 도움을 줄 수 있음을 확인하였다.

  • 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.

  • The purposes of this study was to identify perfume purchasing and using behavior according to men's fashion lifestyle. Self-administered questionnaires were used for data collection. The subjects were 317 men aged 19-40. The results were as follows: First, over half of men had purchased at least one perfume during last year and the price was 30,000-60,000won. Men selected perfumes which harmonized with their image or purposes of using perfumes. Men selected a perfume as a present for their girl friends or wives to convey their concern or love. Most men purchased perfumes at department stores and selected after experiencing samples, and by affecting advertisements of newspapers or journals. Over 60% of men possessed at least one perfume and most of them were imported perfumes. Most men used perfume on a special day such as dates or job interviews, and they received perfume as a gift from their girl friends or wives. Most men used perfumes to enjoy fragrances by themselves and preferred sea fragrance most. Second, factors of men's fashion lifestyle were fashion information, individuality, conservativeness, ostentation, activity, and fashion style. Men were segmented into ostentatious consumption group, active group, fashion leader group, and fashion retard group.

  • Quantitative evaluation of the sense of smell is done by the olfactory event-related potential (OERP) test. OERP consists of N1, P1, N2, P2, and P3, of which N1 and P1 latency are known to be affected by the concentration of odor stimuli associated with the pre-sensory phase and P2 and P3 are the stages at which odors are perceived and are known to change by subjective evaluation of the stimulus. The purpose of this study was to clarify the correlation between the expression of OERP and the subjective evaluation of the object on the fragrance stimulus using various fragrances. Therefore, the study examined the relative waveform power ratio, preference for each scent stimulus, and finally the amplitude and latency change of the components of OERP, N1 and P2. In contrast, it was found that the late P2 response waveform was an effective aroma stimulus recognition waveform in OERP compared to the initial response waveforms.

  • 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.

  • Tree peony is a traditional famous flower of China, and plays an important role in Chinese traditional culture. But the floral scent of tree peony in vivo is little known. In this study, in order to explore the floral composition of tree peony, floral volatiles of six cultivars, including Paeonia suffruticosa 'Zhaofen' (ZF), P. suffruticosa 'Luoyanghong' (LYH), P. ostii 'Fengdanbai' (FDB), P. ${\times}$ lemonei 'High noon' (HN), P. ${\times}$ lemonei 'Renown' (R), and P. rockii 'Gaoyuanshenghuo' (GYSH) were collected by dynamic headspace and then identified by Automated Thermal Desorption-Gas Chromatography/Mass Spectometry. The results showed that floral fragrances of the six cultivars were qualitatively and quantitatively distinct. A total of 105 volatiles involving ten categories were detected. But not all volatile categories were emitted from these cultivars. The six peony cultivars emitted some shared compounds and peculiar compounds. The total released amounts of volatiles emitted from six cultivars were found significantly different, which was greatest for 'GYSH'. The most abundant volatile compounds detected from 'ZF', 'LYH', 'FDB', 'HN', 'R', and 'GYSH' were respectively ${\alpha}$-pinene, 2,3-dihydroxy propanal, 3-methyl-1-butanol, 2-ethyl-1-hexanol, acetic acid 1-methylethyl ester, and 5-ethyl-2,2,3-trimethyl heptane. This result may contribute to exploring the biosynthesis and emission mechanism of floral scent in tree peony.

  • The Seoul Housing Corporation pronounced a design competition for Eunpyeng New Town District 2 in March of 2005. The authors collaborated on this design and won rot prize. Design guidelines of this competition were to make environmentally sustainable design, to develop as a resort site and cultural place for everyday life of residents, to link with green fabric of the district, and to elevate positive image and identity of Eunpyeng New Town district by creating a attractive landscape. The authors developed design concept and strategy within the guidelines and site conditions. The environmental setting of this site was characterized by mountain to the rear of the site with a stream passing through the district and the front of the site. This is the most important condition for the location principle of residence in Fung Shui theory. Therefore, the schema of the design was introduced by Fung Shui and Chi of place. To evolve design concept, we reinterpret the Fung Shui and Chi in the site combining with modem landscape design strategy, so that good place making could bring about well-being life of residents. By doing that, design concept of the proposal evolved as follows: 'fullness of comfortable life', 'adaptation of nature', 'inspiration of natural force'. This design approach is critical reevaluation of regional characters employing modem strategy. It is a conscious strategy of critical regionalism as distinguished from the traditional site oriented approach. The following are some of the major features in the design: green network and water recycle system in the site, promenade of forest with the experience nature, link to community core, theme gardens with plants having strong fragrances, terrace gardens with different level of housing type, playgrounds and resting places with many types, human scale facilities for residents.
