This study evaluated the usefulness of the elasticity score and elasticity ratio in the differential diagnosis of benign and malignant lesion in breast elastography. We performed a retrospective analysis based on the results of core needle biopsy histology. The Mann-Whitney U test was used to confirm the difference between the 5-degree elasticity score and the Fisher's Exact test. ROC curve analysis was used to determine the elasticity score and the best cut-off value of the elasticity ratio for the prediction of malignant lesions. There was a statistically significant difference (p= .000) between the homogeneity of the elasticity score and the difference of the elasticity ratio between the benign and malignant lesion groups. On the ROC curve analysis, the elasticity score and the elasticity ratio for predicting benign and malignant lesion were determined as AUC 0.806, 0.824, cut-off value 3, 4.4 (p= .001). Therefore, the elasticity score and elasticity ratio may be useful in the differential diagnosis of breast mass.

The purpose of this study was to identify the effects of mechanical traction applied to the knee joint on pain, knee range of motion (ROM), timed up and go (TUG) and Western Ontario and MacMaster Universities Osteoarthritis (WOMAC) in patients with knee osteoarthritis (KOA) of Kellgren-Lawrence radiological rating scale II or III. Twenty three patients participated in the experiment for a period of four weeks. After baseline assessment, the patients with KOA were randomized into two groups: the traction group ($n_1=12$), which received traction with general physical therapy; and the control group ($n_2=11$), which received general physical therapy only on unilateral knee joints. Patients received interventions once a day, three times a week, for four weeks. Wilcoxon signed-rank test was used to analyze the change of dependent variances within the group during pre and post intervention. Mann-Whitney U test was used to analyze the change of dependent variances as TUG and passive ROM between the two groups. Analysis of covariance was used to analyze the change of dependent variances as numeric pain rating scale (NPRS) and WOMAC score between the two groups. In Wilcoxon signed-rank test, the traction group improved significantly with regard to NPRS (p<.01), passive knee flexion ROM (p<.01), passive knee extension (p<.05), TUG (p<.01) and WOMAC scores (p<.01) after intervention for four weeks, but not for the control group. In the Mann-Whitney U test and analysis of covariance, no significant difference was seen among all the dependent variances after intervention for four weeks between the two groups. These outcomes suggest that further studies should be carried out to determine the effects of mechanical traction prior to using it for the treatment of patients with knee osteoarthritis.

This study aims to identify the effect of music psychotherapy on motivation for learning in the underachieving student. The study divided nine children into two groups and placed four children in a test group and five children in a control group. After conducting a pre-test, the researcher performed music psychotherapy with the four children in the test group for about 12 weeks, twice a week, totaling 18 sessions. Quantitative data were measured in pre-and-post tests using Mann-Whitney's U-test, and the effects of the therapy were analyzed using Wilcoxon. The findings of this study were as follows. Music psychotherapy was shown to be effective for improving all types of motivation for learning in underachieving students (p < .001). This was shown by assessing improvements in the experimental group across four sub-areas of motivation for learning (p < .1), and directly measured by examining the subjects' lingual responses related to motivation for learning. These results demonstrate that music psychotherapy is effective for enhancing motivation for learning in underachieving students.

This study is a nonequivalent control group pre- and post-test design research whose purpose was to determine what effects the pre-operation provision of information has on the anxiety and uncertainty of mothers with a pre-school child of tonsillectomy and nursing satisfaction after the operation. Data were collected from mothers whose child underwent tonsillectomy at S general hospital. For the collection, those mothers were divided into the experimental and control groups, respectively consisting of 19 and 20 members. The experimental group was provided general education about the operation. In addition, they individually received information about the procedure that the researcher and an assistant provided on one-to-one basis for about 20 minutes, in which brochures containing the information were used. While, the control group was provided only general education as mentioned above. For data analysis, this study conducted ${\chi}^2$-test, Fisher's exact test and Mann-Whitney U-test. The pre-operation provision of information was found having brought significant differences between the control and experimental groups in their anxiety(U=104.5, p=.015) and uncertainty(U=83.5, p=.002) as well as their satisfaction after the operation(U=109.5, p=.022). The findings of this study strongly suggest that information provision before the operation is positively effective in reducing the anxiety and uncertainty of mothers with a tonsillectomy child and increasing their nursing satisfaction after the operation. These effects need to be more verified through repetitive and subsequent researches and by using many other methods of information provision.

The purpose of this research is to apply the neural networks models for the hydrologic disaggregation of the yearly pan evaporation(PE) data in Republic of Korea. The neural networks models consist of multilayer perceptron neural networks model(MLP-NNM) and support vector machine neural networks model(SVM-NNM), respectively. And, for the evaluation of the neural networks models, they are composed of training and test performances, respectively. The three types of data such as the historic, the generated, and the mixed data are used for the training performance. The only historic data, however, is used for the testing performance. The application of MLP-NNM and SVM-NNM for the hydrologic disaggregation of nonlinear time series data is evaluated from results of this research. Four kinds of the statistical index for the evaluation are suggested; CC, RMSE, E, and AARE, respectively. Homogeneity test using ANOVA and Mann-Whitney U test, furthermore, is carried out for the observed and calculated monthly PE data. We can construct the credible monthly PE data from the hydrologic disaggregation of the yearly PE data, and the available data for the evaluation of irrigation and drainage networks system can be suggested.
