Purpose: The purpose of this study was to verify the effect of aromatherapy massage on abdominal fat and body image in post-menopausal women. Method: A Non-equivalent control group pre-post test Quasi-experimental design of random assignment was applied. All subjects received one hour of whole body massage as treatment by the same researcher every week for 6 weeks. Participants also massaged their own abdomen two times everyday for 5 days each week for 6 weeks, The two groups used different kinds of oil. The experimental group used 3% grapefruit oil, cypress and three other kinds of oil. The control group used grapeseed oil. Data was collected before and after the treatment using Siemens Somatom Sensation 4, a tape measure and MBSRQ. Data was analyzed by ANCOVA using the SPSS/PC+Win 12 Version. Result: Abdominal subcutaneous fat and waist circumference in the experimental group significantly decreased after aromathetapy massage compared to the control group. Body image in the experimental group was significantly better after aromathetapy massage than in the control group. Conclusion: These results suggest that Aromatheapy massage could be utilized as an effective intervention to reduce abdominal subcutaneous fat, waist circumference, and to improve body image in post-menopausal women.

This study investigated the effect of vitamin $B_6$ deficiency on antioxidant enzyme activities and lipid profile in rats with exercise-induced oxidative stress. Forty eight rats were fed either a vitamin $B_6$ deficient diet (B6-) or a control diet (control) for 4 weeks and then subdivided into 3 groups: pre-exercise (PreE); post-exercise (PostE); recess after exercise (recessE). Compared to those of control group, plasma catalase and hepatic cytosol superoxide dismutase (SOD, EC 1.15.1.1) activities of B6- group were lower regardless of exercise. The ratio of reduced glutathione/oxidized glutathione (GSH/GSSG) of B6 - group was lower in PreE and there was no difference between PostE and recessE. The level of malondialdehyde (MDA) of B6- was significantly higher in PreE and PostE. High-density lipoprotein-cholesterol (HDL-C) level of B6- group was lower regardless of exercise. Atherosclerotic index of $B_6$- group was higher in PreE and there was no difference between PostE and recessE. It is suggested that a reduction in antioxidative status caused by vitamin $B_6$ deficiency may be aggravated under exercise-induced oxidative stress.

Fused Deposition Modeling (FDM) parts are made by piling up thin layers that cause the stair stepping effect at the surface of FDM parts. This effect brings about poor surface roughness of the part and requires additional post machining such as manual finishing that is detrimental to the part geometry and time consuming. Determining optimal build orientation for FDM parts can be one solution to minimize the post machining. However, by using the CAD model, calculating the optimal build orientation is impractical due to heavy computing process. In order to calculate the optimal build orientation with high speed. the surface roughness model based on measured data and interpolation is newly developed in this research. Also. the genetic algorithm (GA) is applied for acquiring reliable solution. Finally, It is verified from the test that the presented approach is very efficient for reducing the additional post machining process fer FDM parts.

Purpose: This study was conducted to investigate the effect on factors related lactation after administration of Palmul-tang in postpartum C57BL/6N mice. Materials and Methods: Experimental groups were divided into control group post-par group and pre-par group. Pre-par and post-par group were administered Palmul-tang(p.o) twice a week for 4 weeks or 3 weeks respectively. Control group was administered normal saline for 3 weeks. Then we observed morphological change, immunohistochemical density and milk protein gene expression of factors related lactation within mammary gland of postpartum mice. Results: In post-par and pre-par groups, adipose tissue within mammary gland significantly decreased, and ductal branch and alveoli prominently developed than that of control group at 1~3 weeks after administraion of Palmul-tang. In post-par and pre-par groups, density of immunoreactivity on oxytocin, prolactin, estrogen and progesterone receptors in mammary glandular tissue significantly increased than that of control group. mRNA expression of $\beta$-casein and placental lactogen (PL)-1 in post-par group was more increased than that of control and pre-par groups. Conclusion: These results suggest that Palmul-tang significantly improved factors related lactation at postpartum period.

Post-tonsillectomy pain in children is a difficult problem to manage. We examined the effect of 10% aerosol lidocaine for the post-tonsillectomy analgesia. ASA physical status I or II, between five and thirteen years of age were assigned, in a randomized fashion, into two groups. The Group I, 30 patients, received a total dose of 4 mg/kg of ten percent aerosol lidocaine on the tonsillar beds. Lidocaine was administered at the end of the surgical procedure. The Group II, 30 patients, were not sprayed with lidocaine aerosol. The postoperative pain scores were assessed by a "red and white" visual analoge pain scales (VAPS). VAPS values were obtained at one and eight hours after the operation. Values of one hour after the operation in the group I and II were $20.83{\pm}10.01$ and $34.50{\pm}10.53$, values of eight hours after the operation were $17.33{\pm}9.07$ and $23.5{\pm}11.08$. The post-tonsilectomy pains were significantly lower in the group I compared with the group II at one and eight hours after the operation. In conclusion, 4 mg/kg of ten percent aerosol lidocaine applied directly on the tonsillar beds was showen a superior, immediate post-tonsillectomy analgesic technique.

The effects of post-CMP cleaning on the chemical and galvanic corrosion of copper (Cu) and titanium (Ti) were studied in patterned silicon (Si) wafers. First, variation of the corrosion rate was investigated as a function of the concentration of citric acid that was included in both the CMP slurry and the post-CMP solution. The open circuit potential (OCP) of Cu decreased as the citric acid concentration increased. In contrast with Cu, the OCP of titanium (Ti) increased as this concentration increased. The gap in the OCP between Cu and Ti increased as citric acid concentration increased, which increased the galvanic corrosion rate between Cu and Ti. The corrosion rates of Cu showed a linear relationship with the concentrations of citric acid. Second, the effect of Triton X-$100^{(R)}$, a nonionic surfactant, in a post-CMP solution on the electrochemical characteristics of the specimens was also investigated. The OCP of Cu decreased as the surfactant concentration increased. In contrast with Cu, the OCP of Ti increased greatly as this concentration increased. Given that Triton X-$100^{(R)}$ changes its micelle structure according to its concentration in the solution, the corrosion rate of each concentration was tested.

Reductions in strength and range of motion in older persons have been associated with decreased functional mobility and risk of falls. The purpose of this research was to investigate the effect of intensive dynamic balance exercise (DBE) during 8 weeks on onset time of medial gastrocnemius and tibialis anterior muscle contraction after perturbation in older women. Thirty subjects were randomly assigned into DBE group or control group. The DBE group participated in 50 minutes 3 days a week for 8 weeks. Surface electromyography (EMG) activity was recorded from the medial gastrocnemius and tibialis anterior muscles of left side. Outcome data were collected both groups at the pre-exercise and post-exercise. Independent t-test and paired t-test were used to determine the statistical difference. Results showed that the passive range of motion and functional reach test were significantly increased in the DBE group than the control group at the post-exercise (p<.05). The onset time of both muscles and discrepancy of onset time significantly reduced in the DBE group than the control group at the post-exercise (p<.05). The onset time of both muscles were significantly reduced in the post-exercise than the pre-exercise in the DBE group (p<.05). The discrepancy of onset time in the DBE group was significantly reduced in the post-exercise than the pre-exercise (p<.05). These findings suggest that intensive dynamic balance exercise for the eight weeks was effective in improving the postural control with older persons.

The purpose of this study is to analyze the effects of unstructured and spontaeous role-playing in pro-social behavior of a child. The experimental group in this study is 7 children who go to after-school class in J. social welfare facility and the controlled group is 7 children in composition class., While the experimental group did role-playing with each other the control group did not have any treatment, In order to find out effects of an experiment pre-test first post-test and second post-test were done. The results can be concluded as following. First in pre-test the degree of behavior resulted the same in experimental group and in controlled group. However in the first post-test the pro-social behavior of the experimental group with role-playing showed an improve than that of the controlled group. Therefore it can be emphasized once more that the role-playing improves pro-social behavior of a child. Second in the second post-test done 2 moth after the role-playing it was found that the pro-social behavior of experimental group keep the improved points as in the first post-test Therefore it can be concluded that the effect of role-playing on pro-social behavior of a child is continuous.

Bokeh effect is a stylistic technique that can produce blurring the background of photos. This paper implements to produce a bokeh effect with a single image by post processing. Generating depth map is a key process of bokeh effect, and depth map is an image that contains information relating to the distance of the surfaces of scene objects from a viewpoint. First, this work presents algorithms to determine the depth map from a single input image. Then, we obtain a sparse defocus map with gradient ratio from input image and blurred image. Defocus map is obtained by propagating threshold values from edges using matting Laplacian. Finally, we obtain the blurred image on foreground and background segmentation with bokeh effect achieved. With the experimental results, an efficient image processing method with bokeh effect applied using a single image is presented.
