Purpose: The purpose of this study was to identify the effects of aroma inhalation therapy on nausea, vomiting, abdominal discomfort, compliance, and colon cleansing for patients having a colon lavage solution before colonoscopy. Methods: This study was performed using a nonequivalent control group post-test design. The study was conducted from 20 Jun to 29 Aug, 2011. The participants were 152 patients (experimental group: 77, control group: 75) who underwent colonoscopy at A hospital, Seoul. Results: The experimental group with the aroma inhalation therapy reported significantly lower nausea and vomiting than did the control group. There were no significant differences in abdominal discomfort, compliance, and colon cleansing between experimental and control group. Conclusion: Use of an aroma inhalation therapy was efficient in nausea and vomiting among patients having a colon lavage solution before colonoscopy. Therefore, aroma inhalation therapy is recommended as an effective nursing intervention for relieving nausea and vomiting among patients having a lavage solution before colonoscopy.

Purpose: The purpose of this study was to examine the effects of oral gargling with an aromatic solution on xerostomia, objective oral status, and oral health-related quality of life in psychiatric inpatients. Methods: A nonequivalent control group with a non-synchronized design was used in this study. The experimental group (n=34) received oral gargling with an aroma solution, while the control group (n=33) gargled with 0.9% normal saline. Dependent variables were measured at pre-, post-, and follow-up test. Data were analyzed using an χ²-test, Fisher's exact probability test, t-tests, and repeated measures ANOVA using SPSS/WIN v.21.0. Results: After the intervention, significant differences were revealed in xerostomia (F=15.30, p<.001), objective oral status (F=38.44, p<.001), and oral health-related quality of life (F=62.70, p<.001) with an interaction effect between group and time. Conclusion: These findings indicate that gargling with an aroma solution is more effective than 0.9% normal saline for the oral health of psychiatric inpatients. Therefore gargling with an aroma can be safely recommended as a brief, economical, and positive intervention in clinical settings.

Purpose: This study was conducted to examine the effect of oral care with an aroma solution on oral status and oral cavity microorganism growth in elderly patients with stroke. Methods: A non-equivalent control group, with a pretest-posttest design was used in this study. The participants were assigned to the experimental group (n=30) that received oral care with an aroma solution or the control group (n=31) that received 0.9% saline solution. To identify the effect of the experimental treatments, objective/subjective assessments of oral status and oral cavity microorganism growth were performed using the oral assessment guide, oral perception guide, and oral swab culture. Data were analyzed using Chi-square test, Fisher's exact test, and t-test with the SPSS version 21.0 program. Results: The objective oral status was significantly lower in the experimental group than in the control group (t= -3.64, p<.001). There was no significant difference between the subjective oral status of the experimental group and control groups (t= -1.24, p=.109). Oral microorganism growth was significantly lower in the experimental group than in the control group (t= -7.39, p<.001). Conclusion: These findings indicate that special mouth care using an aroma solution could be an effective oral health nursing intervention for elderly patients with stroke.

Objectives : To evaluate the effects of aroma hand massage on sleep disturbance and depression in hospitalized elderly patients. Methods : The data was collected using questionnaires from the subjects who were admitted to the G Medical Hospital in Daegu from 7 July to 12 July, 2008. A total of 23 subjects were selected. The subjects were applied with the aroma hand massage to both hands using a solution diluting four drops of lavender oil in jojoba oil 10cc. Aroma hand massage was given for 10 minutes, one time a day, during 5 days. Results : There was statistically significant improvement on the Korean sleep scale(t=-7.614, p=0.000) and on the Geriatric Depression Scale Short Korea Version(GDSSF-K)(t=3.444, p=0.002). Conclusions : aroma hand massage is an effective therapeutic intervention for decreased sleep disturbance and depression. Therefore, aroma therapy and hand massage by therapeutic intervention is recommended for improving psychological and physiological functions in hospitalized elderly patients.

The purpose of this study was to identify the effects of aroma hand massage and hand massage on sleep disturbance and depression in hospitalized elderly patients. The study was performed using a nonequivalent control group pretest-posttest design. The data was collected by using questionnaires and the measured values from 1 June to 31 August, 2006. The subjects who were admitted to the B Medical Center Hospital in Busan. A total of 40 subjects were selected : 20 in the experimental group and 20 in the control group. The aroma hand massage was administered to the experimental group, and hand massage was given to the control group. The experimental group were applied the aroma hand massage executed by methods such as effleurage, circling, pressing, etc. to both hands using a solution diluting six drops of lavender oil, and bergamot oil, 3% in jojoba oil 20 cc. In the experimental group, aroma hand massage was given for 10 minutes, three times a week, during 2 weeks. The control group receiving the hand massage was given the massage for 10 minutes every two days for 2 weeks. The result of the study are as follows : 1) The first hypothesis : "The Experimental group would have a higher degree of sleep score than the control group" was supported(F=31.798, p=p<0.001). 2) The second hypothesis : "The Experimental group would have a lower degree of depression score than the control group" was supported(F=21.743, p<0.001). Aroma hand massage is an effective nursing intervention for decreased sleep disturbance and depression. Therefore, aroma hand massage by nursing intervention is strongly recommended for improving psychological and physiological functions in hospitalized elderly patients.

Aroma-active compounds were evaluated from salt-fermented anchovy sauce by solid phase microextraction-gas chromatography-olfactometry (SPME-GC-O) based on sample dilution analysis (SDA). SPME extract from carboxen/polydimethylsiloxane (CAR/PDMS) fiber was the most similar to the original odor of salt-fermented anchovy sauce used for this experiment, followed by divinylbenzene/CAR/PDMS (DVB/CAR/PDMS) fiber. Because salt-fermented anchovy sauce contains 23% NaCl, NaCl concentration of diluent was considered when salt-fermented anchovy sauce was serially diluted. Linear relationship between GC response and sample concentration was observed when diluted with 23% NaCl solution, whereas not observed when diluted with deodorized distilled water. Eleven and 16 aroma-active compounds were detected by SPME-GC-O based on SDA using CAR/PDMS and DVB/CAR/PDMS fibers, respectively. Butanoic acid and 3-methyl butanoic acid showed the highest ${\log}_2SD$ factors for CAR/PDMS and DVB/CAR/PDMS fibers. Dimethyl trisulfide, methional, trimethyl amine, 1-penten-3-ol, and acetic acid were also detected as potent aroma-active compounds.

로즈마리의 주요 항기 성분인 pinene, myrcene, cineol이 에탄올 용액에 흡수되는 물질전달 현상을 이해하기 위해 에탄올 농도에 따른 가스상 향기성분의 농도와 70% 에탄올 농도에서의 무차원 헨리상수를 구하였다. 에탄올 농도에 따른 가스상의 농도를 측정한 결과 3가지 화합물 모두 에탄올 농도가 증가함에 따라 headspace 농도가 감소하는 경향을 나타내었으나 화합물의 종류에 따라 다른 유형을 나타내었다. Cineol의 에탄올 농도(x)에 따른 무차원 헨리상수식은 $Hi=(-5.75+x)/(-7017.6+257.3{\times}x)$이며 1 atm, $25^{\circ}C$, 70% 에탄올 용액에서 무차원 헨리상수는 cineol은 0.0058, myrcene은 0.0182, pinene은 0.0365 이었다.

본 연구는 투과증발법을 이용하여 수용액 중 미량의 감귤 향 성분을 농축하는 방법으로, 4종류의 실록산계 고분자 복합막을 이용하여 막 종류와 구조에 따른 투과 특성을 살펴보았다. 또한 최적의 막을 선정하여 공급액의 온도와 농도, 순환 유속에 따른 투과 특성을 살펴보고, 이를 resistance-in series model을 이용하여 해석하였다. 4종류의 실록산계 고분자 복합막을 통한 감귤 essence aroma 모델액의 투과 실험에서 지지층이 polyvinylidene fluoride (PVDF)이고 활성층이 polyoctylmethyl siloxane (POMS)인 막이 가장 높은 향 성분 플럭스와 농축계수 값을 나타내었으며, 공급액의 온도와 농도, 순환유속을 변화시키며 투과 실험을 하였다. 그 결과 공급액의 온도와 농도가 증가됨에 따라 향성분의 플럭스는 증가하고 농축계수 값은 감소하였으며 순환유속이 증가됨에 따라 향성분의 플럭스와 농축계수 값 모두 증가하였다.
