  • Identifying highly discriminating genes is a critical step in tumor recognition tasks based on microarray gene expression profile data and machine learning. Gene selection based on tree models has been the subject of several studies. However, these methods are based on a single-tree model, often not robust to ultra-highdimensional microarray datasets, resulting in the loss of useful information and unsatisfactory classification accuracy. Motivated by the limitations of single-tree-based gene selection, in this study, ensemble gene selection methods based on multiple-tree models were studied to improve the classification performance of tumor identification. Specifically, we selected the three most representative tree models: ID3, random forest, and gradient boosting decision tree. Each tree model selects top-n genes from the microarray dataset based on its intrinsic mechanism. Subsequently, three ensemble gene selection methods were investigated, namely multipletree model intersection, multiple-tree module union, and multiple-tree module cross-union, were investigated. Experimental results on five benchmark public microarray gene expression datasets proved that the multiple tree module union is significantly superior to gene selection based on a single tree model and other competitive gene selection methods in classification accuracy.

  • Purpose : The purpose of this study was to investigate the effect of Vojta therapy on Gross Motor Function Measurement(GMFM) and Selective Voluntary Motor Control (SVMC) in children with Spastic diplegia. Methods : During this experiment, the subject of four children diagnosed with spastic diplegia was tested using ABA design for Single-subject Experimental Research Design. The procedure consisted of baseline, intervention and follow-up phase which was held thirty minutes each for three times a week for a total of 24 times. Gross motor function was measured using GMFM and selective voluntary motor control was measured using SCALE. Results : According to this study, the gross motor function and selective voluntary motor control of all subjects were improved from their intervention phase to their baseline phase. During the follow phase which the intervention was removed, the ability that was enhanced during the prior phases was still either maintained or only reduced slightly. Conclusion : The Vojta therapy used on children diagnosed with spastic diplegia was effective on both GMFM and SVMC. In other words, the therapy was effective on coordination. However, this study is difficult to be generalized due to the insufficient number of subject. In further studies, it will be necessary to increase the number of trials with a control group in order to generalize the effectiveness of Vojta therapy.

  • Objectives: This study was performed to analyze the toxicity and to find the lethal dose of the test substance Hominis placenta pharmacopuncture when used as a single-dose in 6 week old, male and female Sprague-Dawley (SD) rats. Methods: All experiments were conducted at Biotoxtech (Chungwon, Korea), an institution authorized to perform non clinical studies, under the regulations of Good Laboratory Practice (GLP). SD rats were chosen for the pilot study. Doses of Hominis placenta pharmacopuncture extracts, 0.125, 0.25 and 0.5 mL, were administered to the experimental group, and 0.5 mL doses of normal saline solution were administered to the control group. This study was conducted under the approval of the Institutional Animal Ethics Committee. Results: No deaths or abnormalities occurred in any of the groups. Also, no significant changes in body weights were observed among the groups, and no significant differences in hematology/biochemistry, necropsy, and histopathology results were noted. Hematologically, some changes in the male rats in two experimental groups were observed, but those changes had no clinical or toxicological meaning because they were not dose dependent. Histopathological tests on the injected parts showed cell infiltration in the male rats in one of the experimental groups; however, that result was due to spontaneous generation and had no toxicological meaning. Therefore, this study showed that Hominis placenta pharmacopuncture had no effect on the injected parts in terms of clinical signs, body weight, hematology, clinical chemistry, and necropsy. Conclusion: As a result of single-dose tests of the test substance Hominis placenta pharmacopuncture in 4 groups of rats, the lethal dose for both males and females exceeded 0.5 mL/animal. Therefore, the above findings suggest that treatment with Hominis placenta pharmacopuncture is relatively safe. Further studies on this subject are needed.

  • Purpose: This study examined the effects of the application of Schroth exercise-based instrument Pilates exercise on the Cobb's angle, angle of trunk rotation, and low back pain of female patients with idiopathic scoliosis. Methods: Three patients with idiopathic scoliosis at a Cobb's angle of 20° or more participated in this study. Among the single-subject experimental research designs, a reversal (ABA) design was performed. In particular, Schroth exercise-based instrument, Pilates exercise, was performed for 10 weeks, consisting of five weeks between the baseline and intervention one period and five weeks between the intervention 1 and intervention 2 periods, and then followed up for five weeks. Results: After the Schroth exercise-based instrument, Pilates exercise, was applied, the Cobb's angle and the angle of trunk rotation decreased compared to the baseline in all subjects, and the follow-up period also showed a continuous decline. After Pilates exercise was performed, low back pain in subjects 1 and 2 was decreased in the intervention 1 period compared to the baseline. The level of low back pain in the intervention 2 period increased compared to the intervention 1 period, but a reduction was noted in the follow-up period. The low back pain in the subject was decreased in all intervention periods and the follow-up period. Conclusion: Schroth exercise-based Pilates exercise improves the Cobb's angle and the angle of trunk rotation for female patients with idiopathic scoliosis in their teens and 20s, and an effective intervention method is proposed for low back pain.

  • Objectives: This study was performed to analyze the single-dose toxicity of neutral natured blood stasis pharmacopuncture extracts. Methods: All experiments were conducted at Biotoxtech, an institution authorized to perform non-clinical studies, under the regulations of Good Laboratory Practice (GLP). Sprague-Dawley rats were chosen for the pilot study. Doses of neutral natured blood stasis pharmacopuncture extracts, 0.1, 0.5 and 1.0 mL, were administered to the experimental group, and the same doses of normal saline solution were administered to the control group. This study was conducted under the approval of the Institutional Animal Ethics Committee. Results: In all 4 groups, no deaths occurred, and the neutral natured blood stasis pharmacopuncture extracts administered by intramuscular (IM) injection was over 1.0 mL/animal. No significant changes in the body weights between the control group and the experimental group were observed. To check for abnormalities in organs and tissues, we used microscopy to examine representative histological sections of each specified organ; the results showed no significant differences in any organs or tissues. Conclusion: The above findings suggest that treatment with neutral natured blood stasis pharmacopuncture extracts is relatively safe. Further studies on this subject should be conducted to yield more concrete evidence.

  • In this study we developed monosyllable lists for articulation test for Korean. We sampled 103,581 colloquial monosyllables, applied them to five selection rules that based on Korean linguistic characteristics, and finally constructed five different lists with fifty monosyllables. The validity test using the monaural impairment factors such as S/N ratio and cut-off frequency showed that articulation scores were chanted systematically according to the level of impairment factors. In addition, we investigated the effect of azimuth of a single competing sound upon articulation scores. The syllables were always reproduced by the loudspeaker in front of the subject, while Hoth noise were reproduced by the loudspeaker with varying azimuth around subject. The result indicated that the articulation depended on the azimuth of competing sound sources. Finally, no significant differences among lists were found in all experimental conditions.
