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.

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.

In order to estimate the mass transfer characteristics of absorption into alcohol solution of aroma compounds such as cineol, myrecene and pinene which are major aroma compounds of rosemary, dimensionless Henry's constant in 70% ethyl alcohol concentration and aroma concentration with different ethyl alcohol concentration were analyzed. From the results of measurement of vapor phase concentration of aroma compounds with different ethyl alcohol concentration, headspace concentrations of all of three aroma compounds were decreased as ethyl alcohol concentration increased. But those patterns were slightly different. Dimensionless Henry's constant equation (Hi) of cineol compound with ethyl alcohol concentration (x) was as follows: $Hi=(-5.75+x)/(-7017.6+257.3{\times}x)$. Dimensionless Henry's constants of cineol, myrecene and pinene in 1 atm, $25^{\circ}C$ and 70% ethyl alcohol concentration were 0.0058, 0.0182 and 0.0365, respectively.

This is the research about the concentration of trace citrus flavor components in water by pervaporation. We have investigated the permeation characteristics depending on the material and formation of membranes using four siloxane-based polymer composite membranes. We have also chosen the optimal membrane and investigated the permeation characteristics depending on the feed temperature, concentration and flow rate. And then it has been analyzed by using resistance-in series model. In the permeation experiment of citrus essence aroma model solution through the four siloxane-based polymer composite membranes, PVDF/POMS membranes have showed the best flavor flux and enrichment factor. As a result of the permeation experiment depending on the feed temperature, concentration and flow rate, we can find that as the feed temperature and concentration increase, the flavor flux increases while the enrichment factor decreases. And the flavor flux and enrichment factor increased as the flow rate increases.
