  • A study on the factors affecting oral health beliefs of some high school third graders on oral health promotion behavior After the oral health education on November 21, 2017, 160 students who explained and agreed on the study purpose and method were final analyzed. Oral health belief and oral health promotion behavior according to general characteristics were analyzed with t-test, one-way ANOVA, and the correlation with Pearson's correlation test. The convergence factors affecting oral health promotion were performed multiple regression analysis. The convergence factors affecting oral health promotion were performed multiple regression analysis. Oral health belief was the highest with 3.61 points, with 4.06 points of benefit, while oral health promotion with 3.25 points. Convergence factors affecting oral health improvement were shown as susceptibility (${\beta}=-0.210$), salienece(${\beta}=0.396$), seriousness(${\beta}=0.306$), and barrier(${\beta}=-0.170$). To explore ways to change the oral health beliefs of high school students, the school district health education is very important, and various oral health education programs to promote oral health promotion should be developed.

  • The purpose of this study was to development of the 'convergence motive' scale for interdisciplinary knowledge fusion. Based on results from literature review, this study clarifies a theoretical ground for 'convergence motive'. Initial items to measure this concept were verified by content analysis and then finalized. After a pilot test done with 568 college students, gathered data were analyzed by item selection and exploratory factor analysis to verify their validity. Next, the main test implemented with 1,211 college students was analyzed with exploratory factor analysis using the method for rotation based on maximum likelihood analysis and direct oblimin for validating the final items to measure 'convergence motive'. As a result, the scale for 'convergence motive' consists of 43 items to measure the following four factors: collaboration to identifying and solving problems, challenge of a new perspective, communication for convergence, cohesion for convergence. Construct validity and criterion-related validity were performed at last to check this scale's theoretical construct. In conclusion, this study concluded that the scales for convergence motive could be generalized and applicable to other samples.

  • The purpose of this convergence study was to identify the effects of favorite music therapy on anxiety, fatigue, and vital signs of patients undergoing prostatectomy with spinal anesthesia. This study used a nonequivalent control group design. A sample of 45 patients was included. The experimental group was given music therapy during operation. The data were collected using a structured questionnaire and monitoring at 30 min before operation, at 20 min and 40min undergoing operation, and at arrival recovery room after operation. Data were analyzed using descriptive statistics, ${\chi}^2-test$, Fisher's exact test, t-test, repeated measures ANOVA. The experimental group reported significantly lower anxiety and lower fatigue than the control group(p=.001; p=.020). However there were no significant differences in the systolic blood pressure, diastolic blood pressure and pulse rate between groups(p=.821; p=.473; p=.782). This findings indicate that the tailored favorite music therapy can be an effective nursing intervention for patient undergoing prostatectomy with spinal anesthesia to reduce anxiety and fatigue related to operation.

  • This study is a convergence study of 596 high school girls in order to confirm the relationship between the desired number of meat side dishes and preference of fish side dishes in school meals. Data were analyzed by χ2-test, ANOVA-test, and Duncan's test using SPSS 22.0 program. The results of the study were as follows. The scores of the subjects for promoting palatability were highest in the items 'Easy to eat' and 'Without fishy'. The scores of 'Nutrition Education', 'Combined with Preferred Food', 'Without Fishy' and 'Add Preferred Flavor' tended to increase significantly as the desired frequency of meat side dishes increased from 'less than three times a month' to 'more than five times a week'. The findings of the study confirmed the relationship between the desired frequency of meat side dishes and preference of fish side dishes. Therefore, this study is expected to provide high school girls with a way to increase fish preference.

  • The method of moments (MoM) is implemented to simulate scattering from a PEC (perfectly electric conductor) cylinder in the TE(transversw electric) EFIE (Electric Field Integral Equation) approach. The procedure expresses the singularity integral and the hypersingularity integral in terms of an analytic function and employs a singularity isolation process coupled with numerical technique along the discretized segment to evaluate the self terms. It is known that, in the MoM technique, the choice of base functions and test functions is very important for the accuracy and convergence of the numerical analysis. Thus, in this paper, three conditions, obtained from the combination of basis functions and test functions, are adopted to get the induced currents on the PEC surface. These currents are compared to the analytical one in the relative rms current error to get the condition that shows fast convergence rate. The fast order of convergence of the current error, 2.528, is obtained under the combination of pulse basis function/delta test function.

  • In this paper, the baseline-length information is directly modeled as a measurement for the Wald test, which speeds up the resolution convergence of the integer ambiguity of GPS carrier phase measurements. The convergent speed improvement is demonstrated using numerical simulation and real experiments. It is also shown that the integer ambiguities can be resolved using only four actual satellite measurements with very reasonable convergence speed, if the baseline-length information is used just like one additional observable satellite measurement. Finally, it is shown that the improvement of convergence speed of the Wald test is due to the increase of the probability ratio with the use of the baseline-length constraint.

  • The degradation behavior of fuel cladding is a very import concern in nuclear power generation, because the operation of nuclear plants can be limited by fuel cladding degradation. In order to evaluate the hydride effect on failure of zirconium fuel claddings, a ring tensile test for the circumferential direction was carried out at room temperature for claddings having different hydride characteristics such as density and orientation; microstructural evaluation was also performed for those claddings. The circumferential failure of the claddings was promoted by increasing the hydride concentration in the matrix; however, the failure of the claddings was affected by the hydride orientation rather than by the hydride concentration in the matrix. From fracture surface observation, the cladding failure during the ring tensile test was matched with the hydride orientation.

  • In this paper, the classical Irons' patch tests which have been generally accepted for the convergence proof of a finite element are performed for Mindlin plate bending elements with a special emphasis on the nonconforming elements. The elements considered are 4-node and 8-node quadrilateral isoparametric elements which have been dominantly used for the analyses of plate bending problems. It was recognized from the patch tests that some nonconforming Mindlin plate elements pass all the cases of patch tests even though nonconforming elements do not preserve conformity. Then, the clues for the Mindlin plate element to pass the Irons' patch tests are investigated. Also, the convergent characteristics of some nonconforming Mindlin plate elements that do not pass the Irons' patch tests are examined by weak patch tests. The convergence tests are performed on the benchmark numerical problems for both nonconforming elements which pass the patch tests and which do not. Some conclusions on the relationship between the patch test and convergence of nonconforming Mindlin plate elements are drawn.
