This study examined effects of the communication accompanied with music therapy on the anxiety of patients during a MRI examination. In the experiment group consisting of thirty patients and the control group consisting of thirty patients, the experiment was performed from February 1st 2014 to March 31st 2014 in hospital C located in Daegu Korea. The research design was a non-equivalent control group quasi-experimental study. The results showed that the anxiety score (VAS score) on communication with music therapy of the experimental group was significantly lower (p=.001), than that of the control group. Among the vital signs, the blood pressure was similar in both groups. On the other hand, the pulse rate of the experiment group was significantly lower (p=.001). Four categories of the physical discomfort (perspiration, facial change, change in physical posture, and change in vocal sound) did not show any statistically significant difference between the control and experiment group. Among the mental discomforts, dizziness did not have a significant difference between the experiment group and the control group, but the experimental group had significantly low fear (p=.001) and anxiety (p=.001). From the above results, communication accompanying music therapy proves is an effective alternative examination method that reduces the anxiety of patients.

Purpose : Numerous methods exist for diagnosing nonpalpable testis in treatment of cryptochidism. However, there is no clinically established data for the rational diagnostic tool of nonpalpable testis in terms of expenses. We tried to establish a current conventional diagnostic course of nonpalpable testis. We then evaluated the efficacy of ultrasonography, physical examination under general anesthesia and laparoscopy for diagnosing nonpalpable testis. Methods : Between March 2000 and February 2005, 103 boys(129 testes) with undescended testes were treated in our department. There were 31 testes(24.0%) that were not palpable at physical examination. These patients were evaluated with ultrasonography and repeated physical examination under general anesthesia. In the cases where testes could not be detected with ultrasonography and physical examination under general anesthesia, laparoscopy was performed to diagnose nonpalpable testis. Results : In 31 cases of nonpalpable testis, 13 testes were detected with ultrasonography and 15 testes became palpable with physical examination under general anesthesia. All of the remaining 16 nonpalpable testes were confirmed with laparoscopy. Conclusion : Physical examination under general anesthesia was superior to ultrasonography in making a diagnosis of nonpalpable testis. Ultrasonography and physical examination under general anesthesia could reduce the incidence of diagnostic laparoscopy. Therefore, it is recommended that ultrasonography, physical examination under general anesthesia and laparoscopy must be performed conventionally in order to diagnose nonpalpable testis.

Epididymal biopsy has been performed without consideration of the possibility of epididymal ductal severance and obstruction which result in obstructive azoospermia. An attempt was made to study the effect of the epididymal biopsy on the obstruction of the epididymal ducts. Bilateral epididymal biopsies were done in 8 healthy rabbits (New Zealand White strain) weighing over 3 kg, and then ejaculated semens have been analyzed 5 times every other week from 1 month after biopsies. Microscopic examination of the biopsied epididymides was also done after the 5th semen analysis. The results were as follows. 1. Semen analysis: 6 out of 8 rabbits showed azoospermia from the 4th semen analysis and 2 cases showed normal number of the sperms in the 5th semen analysis. 2, Microscopic examination: 6 cases of azoospermia showed complete obstruction of the biopsied sites of the epididymides, and abscence of sperms in epididymal ducts distal to the biopsied sites of the epididymides. However, recanalization of the epididymal ducts was noted in 2 cases showing normal sperm count. Therefore, it is concluded that the epididymal biopsy should be avoided in patients who want to be fertile, because it may cause the epididymal severance and obstruction of the epididymal ducts.

In this study, the photocatalytic degradtion of D-glucose with the micro channel reactor was performed on the various experimental conditions. To apply the $TiO_2$ coating on the micro channel reactor, $TiO_2$ solution was synthesized by hydrolysis of titanium oxysulfate. The feeding rate was proportional to degradation rate of D-glucose solution over the micro channel reactor. Also, the reaction rate constant and Langmuir adsorption coefficient were calculated under various experimental conditions. And the results of these system photonic efficiencies were calculated. This study aims to understand the photocatalytic degradation characteristics on $TiO_2$ coating in the micro channel reactor experimented by the feed batch reaction system.

Background and Objectives : In oriental Medicine, there is a concept that herb works only in it's own specific site called 'Guikyung(歸經)'. If two herbs have same effect and different Guikyung, two herbs would work at different site respectively. so we want to prove that whether Guikyung has significance or not in experimentally. Methods : In order to investigate the effects of Victicis Fructus & Bupleuri Radix on the Allergic rhinitis, BALB/c mouse was used. Control and experimental group 1, 2 were induced allergic rhinitis. Experimental group 1 was administered Victicis Fructus for 28 days and group 2 was administerd Bupleuri Radix for same period. WBC, neutrophil, lymphocyte, monocyte, IL-4 and $IFN-{\gamma}$ were measured and histological examination was performed. The statistical significance was examined by Independent Samples T test. Results : 1. WBC, neuoophil, lymphocyte, monocyte, IL-4 and $IFN-{\gamma}$ showed no statistically significant differences in three groups. 2. Histological examination had no differences in three groups. Conclusion: Victicis Fructus & Bupleuri Radix have no effect on allergic rhinitis and the reason is estimated that Guikymg plays a important roll to determine the effect of herb from the viewpoint of oriental medicine.

Purpose: The purpose of this study was to determine the effect of BSE education and practice on knowledge, self efficacy and performance in female nursing students. Method: The subjects consisted of 40 students from 2 nursing colleges. They responded to questionnaires that included knowledge, self-efficacy and performance of BSE within a 3-month interval. The experimental group was subjected to a 90 minute-educational session. Their knowledge of BSE was measured using Choi's tool and self-efficacy was measured using Champion and Scott. Result: Self-efficacy and frequency of BSE performance in the experimental group were significantly higher than those of the control group while BSE knowledge was not significantly different between the two groups. Conclusion: Nursing students don't put their knowledge into practice. This fact suggests that changing a behavior needs something more than knowledge. In this study, the BSE education had an effect on self-efficacy and performance. Therefore, practical education needs to be reinforced for nursing students to perform BSE for their own health and to be able to demonstrate it for clients.

Purpose: This study was done to determine the effects of aromatherapy on anxiety and discomfort for patients who were having colonoscopy. Methods: The study used a nonequivalent control group non-synchronized design. The participants were 48 people who were undergoing colonoscopy in a university hospital. The experimental group inhaled a blend of essential oil with neroli, camomile, lavender and lemon through an aroma stone for 5minutes before the examination. Then the aroma stone was put on the side of the pillow to spread the aroma scent in the room. The experimental group could inhale the aroma scent as soon as they came into the room and during the examination process. The control group received only fundamental nursing care. Results: Aromatherapy significantly decreased VAS anxiety. There were also significant differences in facial change and, tone change for objective discomfort. But there were no significant differences in subjective discomfort between the groups nor were there any significant differences in vital signs. Conclusion: Aromatherapy was perceived as an useful intervention to reduce anxiety and objective discomfort of patients receiving colonoscopy. The results of this study could be utilized as a clinical nursing intervention.

This study was focused on the examination of the flame structure and the combustion characteristics of diffusion flame which was formed the turbulent shear flow of a double coaxial air jet system. The shear flow was formed by the difference velocity of surrounding air jet(U$\_$s/) and center air jet (U$\_$c/). So experimental condition was divided S-type flame (.lambda. > 1) and C-type flame (.lambda. < 1) by velocity ratio .lambda. (=U$\_$s//U$\_$c/). For examination of the flame structure and the combustion characteristics in diffusion flame, coherent structure was observed in flame by schlieren photograph method. We measured fluctuating temperature and ion current simultaneously and accomplished the statistical analysis of its. According to schlieren photograph, the flame was stabilized in the rim of the direction of lower velocity air jet, coherent eddy was produced and developed by higher velocity air jet. The statistical data of fluctuating temperature and ion current was indicated that reaction was dominated by higher velocity air jet. The mixing state of burnt gas and non-burnt gas was distributed the wide area at Z = 100 mm of C-type flame.
