Purpose: This study was done to compare the effects of abdominal aroma massage and meridian massage on constipation and stress in college women with functional constipation. Methods: The participants were 38 college women, 18 were in the aroma group and 20 in the meridian group. The aroma massage was given using aroma oil which was a mixture of lemon, lavender, rosemary, and cyprus. The meridian massage was given at 9 accupoints which influence intestinal functions. The treatment was given 5 days a week for 4 weeks. A constipation severity score, weekly defecation frequency, and a stress response score were measured before and every week of 4 weeks of the experiment. Results: While there was no significant difference between two groups, there was a significant difference within the groups in the constipation severity (aroma group: 1st week, meridian group: except 4th week), defecation frequency (aroma group: 3rd week, meridian group: 2nd and 3rd week), and stress (aroma group: all weeks, meridian group: except 4th week) after different duration of experiment. Conclusion: Based on these results, both abdominal massages relieved constipation and stress. Resorting to either types of massage will contribute to the reduction of use of stool softeners, suppositories, or enemas.

본 연구에서는 화상 시뮬레이터 상에서 저속 (40km/h) 주행과 고속 (160km/h) 주행으로 지루감 및 긴장감을 유발시킨 후, 100%의 Jasmine abs와 Lavender oil france (KIMEX Co. Ltd)의 향 자극이 지루함 및 긴장감의 증감에 미치는 영향을 알아보고자 한다. 건강과 피험자 10명을 대상으로 심전도, 피부온도, 맥파의 자율신경계 반응을 측정하였다. 또한 각 실험 전후에 Simulator Sickness를 측정하여 Simulator Sickness가 실험 결과에 미치는 영향을 분석하였다. 지루한 저속 주행 시 향자극이 없을 때에 비해 각 향을 제시하였을 때 각성 효과가 발생하여 교감 신경계가 활성화됨을 자율신경계 반응으로 관찰할 수 있었다. 그러나 두 가지 향에 따라 큰 차이는 발생하지 않았다. 본 연구로부터 일정하고 느린 주행으로 유발되는 신체의 이완 현상 또는 졸리움 현상이 향 자극에 의해 감소되는 경향을 자율 신경계의 반응을 통해 관찰할 수 있었다. 고속 주행 시에는 향을 제시하지 않았을 때보다 두 가지 향을 제시하였을 때 긴장감이 모두 이완되는 경향을 나타내었다. 따라서 고속 주행으로 유발되는 신체의 긴장감이 향 자극으로 인해 감소된다는 사실을 자율신경계의 반응을 통해 관찰할 수 있었다. 그러므로 본 연구로부터 지루한 저속 주행으로 유발된 신체의 이완감과 고속 주행으로 유발된 신체의 긴장감은 각 향 자극에 의해 이완감의 감소와 긴장감의 감소를 유발하였다는 사실을 관찰할 수 있었고, 두 향의 차이는 관찰할 수 없었다.

Purpose: This study was done to examine the effects of aroma inhalation therapy on pain post tonsillectomy. Method: A non-equivalent control group pre- and post-test design was used. The research instruments used in this study were a pain perception measurement and vital signs (systolic & diastolic blood pressure and pulse rate levels). Twenty-five patients in the experimental group went through aroma inhalation therapy for ten minutes after the tonsillectomy. The aroma inhalation therapy used was a blended oil, a mixture of Lavender and Loman chamomile in the ratio of 2:1. The 25 patients in the control group did not receive the therapy. Before and after the experiment, both groups were tested for pain (pain perception and vital signs). Collected data were processed with the SPSS WIN. Ver. 14.0 program and analyzed using frequencies, percentages, ${\chi}^2$-test, Fisher's exact test, t-test and ANCOVA. Results: Pain perception of patients was not significantly reduced. However systolic and diastolic blood pressure and pulse rate were significantly reduced. Conclusion: The results of the study indicate that aroma inhalation is a partially effective nursing intervention to reduce the post-operative tonsillectomy pain.

Culicoides biting midges (Diptera: Ceratopogonidae) are hematophagous arthropod vectors that transmit epizootic arthropod-borne viruses (arboviruses). Arboviruses are recognized as causes of pregnancy loss, encephalomyelitis, and congenital malformations in ruminants. Therefore, continuous monitoring and control of Culicoides, which causes significant damage to industrial animals are necessary. We performed attraction and repellent tests in Culicoides using various essential oils, cow dung, and carbon dioxide (CO₂). Culicoides tended to move more to cow dung (60.8%, P<0.0001) and CO₂ (63.8%, P<0.01). To the essential oils as repellents, 26.1% (P<0.0001), 18.7% (P<0.001), and 25.5% (P<0.01) of the Culicoides moved to the lavender, lemongrass, and eucalyptus chamber, respectively. The Culicoides that moved to the 3 essential oils chambers showed markedly low activity. Collectively, it was showed that Culicoides tended to be attractive to cow dung and CO₂, and repellent from the 3 essential oils.

This study aims to identify research trends and explore the latest methods of applying aromatherapy to the elderly. The main objective is to provide evidence in support of development of an aromatherapy nursing intervention program for the elderly. This investigation is in the form of a literature review focusing on the current status and trends in research conducted on aromatherapy intervention programs for the elderly in Korea over past decade. Published studies were identified through database such as KCI, RISS, DBpia, NDSL. A total 14 studies were selected for this review. The majority of selected articles fall within the field of nursing. The duration of the programs varied, ranging from less than 20 minutes to over 40 minutes, and consisted of 1 to 6 sessions. Most of methods involved massages using lavender oil in a hospital setting. Outcome variables were categorized into three main domains based on significance: psychological-emotional, interpersonal relationship, and physical-physiological. The variables within each category varied with 4 in psychological-emotional, 1 in interpersonal relationship, and 17 in physical-physiological. This review indicates that aromatherapy intervention programs have positive effects on the elderly and suggests the potential for developing similar interventions on a broader scale within community settings in the future.

Environment-friendly agro-materials tend to be preferred to chemical insecticides recently. For this reason, many studies were conducted to develop environment-friendly insecticides containing natural materials. The purpose of this study was to assess ecotoxicity for 5 plant essential oils (Thyme white, Clove bud, Cassia, Lavender, Lemon eucalyptus) expected to prevent from pests and be used for agro-materials. Target species used to assess acute toxicity were aquatic invertebrate (Daphina magna), fish (Oryzias latipes), honeybee (Apis mellifera L.) and earthworm (Eisenia fetida). The EC50 value, toxicological responses of thyme white, clove bud, and cassia to Daphina magna were 2.5, 2.8, and $6.9mg\;L^{-1}$ respectively and these values were moderately toxic according to standard of USEPA. $EC_{50}$ of Lavender and lemon eucalyptus were >$10mg\;L^{-1}$ then they were considered as slightly toxicity. In case of acute toxicity test to fish, $LC_{50}$ of thyme white and cassia were 6.7 and $7.5mg\;L^{-1}$ each other. The other plant essential oils indicated $LC_{50}$ >$10mg\;L^{-1}$. Acute contact and oral toxicity test to Honeybee were conducted. As a result, $LD_{50}$ of all essential oils were >$100{\mu}g$ a.i. $bee^{-1}$ in both of tests. In case of acute toxicity test to earthworm, $LC_{50}$ of thyme white, clove bud, cassia, lavender, and lemon eucalyptus were 149, 230, 743, 234, and $635mg\;kg^{-1}$, respectively. In conclusion, if the safety for earthworm is confirmed, 5 plant essential oils are expected to be use for environment-friendly insecticide materials with low risk against ecosystem and contribute to developing environment-friendly agro-materials.

Purpose: The purpose of this study was to examine the rate of salivation before and after olfactory stimulation using BPO (black pepper oil) and then, to collect basic data for screening the possibility of introducing olfactory stimulus to prevent and improve dry mouth. Methods: The subjects in this study were 60 college students in Jeon-Nam province. The subjects were randomly divided into 3 groups; the BPO group (n=20), the lavender oil (LVO) group (n=20), and the distilled water (DW) group (n=20). The amount of whole saliva before and after olfactory stimulation was measured 14 times for a 4-week period. Results: In the BPO and LVO groups, the amount of whole saliva increased after the olfactory stimulation and it was most prominent in the BPO group (p<0.05). The difference of whole salivation was higher in the BPO group (p<0.05) and there was no significant difference in the salivary flow rate in the DW group. After 14 times of measurement for 4 weeks, the BPO and LVO groups showed an increase in salivary rate at an early stage compared without stimulation (p<0.05), but there was no significant difference between the 2 groups in the middle. Since the twelfth measurement, whole saliva secretion increased and maintained the elevated level (p<0.05). Conclusions: The olfactory stimulation using BPO may contribute to stimulating salivation. Further studies are needed for subjects with dry mouth symptoms. In the future, qualitative and quantitative studies should be conducted for people who complains about oral dryness.

Purpose: The purpose of this study is to identify the effects of aromatherapy on agitation in patients with dementia using a meta-analysis and systemic literature review. Methods: The EMBASE, CINAHL, MEDLINE, and other databases were searched up to November 2017. Results: Of 419 publications identified, 12 met inclusion criteria, and 9 studies were used to estimate the effect size of aromatherapy. A total of 837 participants across all studies were included. The commonly applied methods were massage (50%), type of oil lavender (75%), and instrument Cohen-Mansfield Agitation Inventory (75%). A medium effect size of aromatherapy on agitation was identified (d=-0.56, $I^2=65.0%$, p=.001). The massage group has lower effect size than the other group (d=-0.98, $I^2=0.0%$, p=.001). Conclusion: Aromatherapy appears to be effective in improving agitation in patients with dementia. However, further studies for home-dwelling patients with dementia and with different types of aroma oil should be conducted in the future. In addition, research with well-designed are needed to assess the effects or aromatherapy on agitation.
