'Shine Muscat' (Vitis labruscana Bailey x Vitis vinifera L.) grapes recently have been greatly favored in Korea, and as of 2022, account for 38.6% of the total grape market in Korea. However, there is a lack of research on post-harvest quality control appropriate to the unique characteristics of 'Shine Muscat'. In order to continuously increase domestic demand and exports in the future, it is essential to establish proper postharvest techniques. Essential oils have remarkable potential as biologically active and environmentally friendly antiseptics for the fruit industry. The objective of this study is to evaluate the effects of essential oils and aroma constituent treatment on fruit quality attributes of 'Shine Muscat' grapes in order to extend fruit quality during a simulated export period. A cluster of 'Shine Muscat' grapes was placed in a newly developed paper box container, and treated with rosemary essential oil, thyme essential oil, and linalool, along with an untreated control. The results showed no significant effect on fruit quality indices, such as cluster weight loss, berry firmness, soluble solids content, titratable acidity, sugar acid ratio, and color change, but showed a positive effect on the alleviation of berry shatter compared to the untreated control. In addition, rosemary oil treatment reduced the proportion of unhealthy berries. Therefore, the results indicated that the newly developed packaging container along with certain essential oil treatment could be applied as a promising packaging material for table grape export.

아로마풋스파가 스트레스에 미치는 영향을 알아보기 위해, 스트레스를 가지고 있는 대학생 12명을 대상으로 대조군 6명, 아로마풋스파군 6명으로 나누었다. 대조군은 아무런 처치를 하지 않았으며, 아로마풋스파군은 주니퍼, 라벤더, 레몬 에센셜오일 5%를 이용한 족욕 10분과 마사지크림을 이용한 발마사지 10분을 주 2회 총 4주간 적용하였다. 평가방법은 뇌파를 검사함으로써 스트레스를 변화량을 측정하였다. 실험 전, 후의 뇌파변화를 측정한 결과, 아로마풋스파군의 Alpha파(Z=-2.364, p<.05)와 SMR파(Z=-1.981, p<.05)는 대조군에 비해 더 높은 것으로 나타났다. 또한 아로마풋스파군의 실험 전, 후의 비교에서는 Theta파(Z=-2.366, p<.05)의 수치는 감소하였고, Alpha파(Z=-2.371, p<.05)의 수치는 증가하였다. 즉, 에센셜오일을 이용한 족욕과 발마사지를 실시한 아로마풋스파는 Alpha파의 증가를 일으키고, 이는 근육의 이완으로 인한 혈액순환으로 뇌파에 변화를 주었음을 알 수 있다. 또한 SMR파가 증가함은 Alpha파의 변화와도 관계가 있음을 알 수 있는데 스트레스 완화로 인해 SMR파가 증가되었음 증명해 주고 있다. 따라서 아로마풋스파는 스트레스를 감소시키는데 효과가 있는 것으로 사료된다.

The essential oil of Korean valerian root ( Valeriana fauriei roar. dasycarpa Hara) was isolated by simultaneous distillation Sl extraction. The oil content of fresh root was 0.7% (wb) and that of dried root was 2.1 5 (db) and sensory analysis of the oil indicated sweet-balsamic, woody and floral characteristic aroma notes. The oil was fractionated into one hydrocarbon fraction and three oxygenated hydrocarbon fractions by using silica gel column chromatograpy. Each fraction was analyzed by capillary GC and GC-MS. Out of 81 characterized compounds, the major compounds were a-pinene, camphene, $\beta$-pinene, bornyl acetate, borneol , bornyl iso-valerate and sesquiphellandrene and the characteristic floral and woody aroma of neutral fraction of Korean valerian root could be due to be the presence of oxygenated compounds such as borneol, bornyl acetate, bornyl iso-valerate, p-ionone ana $\beta$-ionone epoxide. Comparing the yield of Korean valerian root with those from other origins reported, oil content of Korean valerian root was higher than those of European and Indian origins.

Purpose: The purpose of this study was to examine the effects of aromatherapy on dysmenorrhea, menstrual pain, anxiety, and depression in female college students. Methods: A two-group cross-over design was used. The sample included a total of 20 female students who were enrolled in a 3 year nursing program. The treatments(aroma essential oil inhalation and the placebo inhalation) were given using a necklace. The data were analyzed by $x^2$-test, paired t-test, and Mann-Whitney test using SPSS/WIN 12.0 program. Results: The level of dysmenorrhea after the aroma treatment was not significantly different from the dysmenorrhea levels at pre-test and after the post-placebo treatment. The menstrual pain, anxiety and depression significantly improved after the aroma treatment. However, the levels of pain, anxiety, and depression after the aroma treatment were not significantly different from those after the placebo treatment. Conclusion: Aroma inhalation may be a effective in managing menstrual pain, anxiety, and depression. In order to further clarify the effect of aroma treatment on discomfort during menstruation, replication studies are necessary. Future studies need to examine the effects of different types of essential oils, administrating methods, and the lasting time of aroma treatment effect.

Objectives : Increasing evidence supports the biological and pharmacological activities of essential oils on the central nervous system such as pain, anxiety, attention, arousal, relaxation, sedation and learning and memory. The purpose of present work is to investigate the protective effect and molecular mechanism of cypress essential oil (CEO) against scopolamine (SCO)-induced cognitive impairments in C57BL/6 mice. Methods : A series of behavior tests such as Morris water maze, passive avoidance, and fear conditioning tests were conducted to monitor learning and memory functions. Immunoblotting and RT-PCR were also performed in the hippocampal tissue to determine the underlying mechanism of CEO. Results : SCO induced cognitive impairments as assessed by decreased step-through latency in passive avoidance test, relatively low freezing time in fear conditioning test, and increased time spent to find the hidden platform in Morris water maze test. Conversely, CEO inhalation significantly reversed the SCO-induced cognitive impairments in C57BL/6 mice comparable to control levels. To elucidate the molecular mechanisms of memory enhancing effect of CEO we have examined the expression of brain-derived neurotrophic factor (BDNF) in the hippocampus. CEO effectively elevated the protein as well as mRNA expression of BDNF via activation of cAMP response element binding protein (CREB). Conclusions : Our findings suggest that CEO inhalation effectively restored the SCO-impaired cognitive functions in C56BL/6 mice. This learning and memory enhancing effect of CEO was partly mediated by up-regulation of BDNF via activation of CREB.

The present study was designed to evaluate central inhibitory effects of an essential oil from Acori graminei Rhizoma (AGR), the dry rhizomes of Acorus gramineus Solander (Araceae) upon fragrance inhalation (aroma therapy). Preinhalation of an essential oil of AGR markedly delayed the appearance of pentylenetetrazole-induced convulsion. Furthermore, the inhalation of an essential oil of AGR impressively inhibited the activity of ${\gamma}$-aminobutyric acid (GABA) transaminase, a degradating enzyme for GABA as inhalation period is lengthened.

The reason that aromatherapy began to draw attention again as the alternative therapy is because the essential oils that are used for aromatherapy not only allow the human body to maintain homeostasis but also have an effect on curing a mental feeling of fatigue and because these efficacies and effects are proceeding with being proved scientifically. Also, with coming to be high in a voice of concern about severally side effects that the modern medicine and the synthetic chemistry have, the aromatherapy came to be paid attention as the replacement therapy that can substitute for and supplement this. In particular, at the time of requiring a study on a substance to substitute for this after having been announced in Japan for 1998 a risk of Zincpyrithione that is being used as a component of dandruff treatment, it is thought that the aroma oil that was known for having an anti-dandruff effect has a merit of being easy in a user's access, thus it will be effective in curing the symptom of dandruff. Accordingly, this study conducted the following experiment in a bid to examine whether the aroma oil has the anti-microbial effect on the actual malassezia. First of all, it measured the minimum concentration of aroma oil in which the growth of malassezia is inhibited, by carrying out MIC(Minimum Inhibition Concentration) test in terms of anti-microbial activity against Malassezia furfur KCTC 7744 while using oils of Patchouli, Rosemary, Lavender, and Tea tree among aroma oils that are being used for dandruff treatment. As a result of that, Tea tree oil has the most excellent anti-microbial activity, and the measurement result of anti-microbial activity was shown in order of Lavender oil>Rosemary oil>Patchouli oil. Next, it carried out the is actually eased by applying Tea tree oil directly to the scalp of dandruff. In consequence of the experiment, the massage of Tea tree oil indicated the result of relieving the symptoms of dandruff such as scale, itch, pain, inflammation, and sebum, and among these symptoms of dandruff, it was shown to be most effective in easing itch. Especially, this clinical experiment was indicated that the massage of Tea tree oil has the most effect on relieving itch of targets with a dry-skin type who had no experience of dandruff treatment.
