Background and Objectives : Many students major in applied music singing have various difficulties in phonation when they sing or perform. But the studies about this cause are lack. The purpose of this study is whether singing voice therapy based on vocal music is effective or not to applied music singing students that have difficulties in phonation. Materials and Methods : Singing voice therapy program had been done to 8 students major in applied music singing during 7 weeks. We did laryngeal stroboscope, perceptual, acoustic and aerodynamic examination before and after singing voice therapy to this students. And we studied post examination results have differences or improvements compared to pre examination results. Results : Four male students don't have effective improvement after singing voice therapy but they shows slight improvement in aerodynamic examination values compared to pre examination values. Four female students shows improvement in aerodynamic examination values and pitch range increasing. Above all, one student's vocal nodules disappeared after singing voice therapy. Conclusion : Singing voice therapy based on music singing is very effective to the students major in applied music singing. Above all, their curriculum in applied music singing should include phonation training based on music singing before training perform and technic practices.

This paper presents a new approach to the design of cruise control system of a mobile robot with two drive wheel. The proposed control scheme uses a Gaussian function as a unit function in the fuzzy neural network, and back propagation algorithm to train the fuzzy neural network controller in the framework of the specialized learning architecture. It is proposed a learning controller consisting of two neural network-fuzzy based on independent reasoning and a connection net with fixed weights to simply the neural networks-fuzzy. The performance of the proposed controller is shown by performing the computer simulation for trajectory tracking of the speed and azimuth of a mobile robot driven by two independent wheels.

동일 개념을 토대로 정성적인 문항과 정량적인 문항을 개발하여 학습자의 오개념 형태와 성취도를 조사하였다. 학생들이 가지고 있는 오개념의 유형은 선행연구의 오개념이 재현되었으며, 정성적인 문항의 정답률이 정량적인 문항보다 높게 나타났다. 학생들이 가지고 있을 것으로 예상하는 교사의 예측 오개념은 대체적으로 학생의 오개념과 일치하였으나 교사가 생각하지 못하는 학생들의 오개념도 정성적인 문항보다는 정량적인 문항에서 더 많이 나타났다. 교사가 가지고 있는 오개념의 유형은 정성적·정량적인 문항의 형태에서 학생들과 비슷하게 나타났는데 물리를 전공하지 않는 교사의 상당수가 물리현상에 대한 오개념을 가지고 있었다. In this study, the patterns of evaluation questions of force and motion are compared, after dividing them into quantitative items, which are widely used in school evaluations, and qualitative items, which are widely used in investigating science misconception, to investigate the relation between students' and teachers' misconceptions and misconceptions presumed by teachers. For this study, the subjects, three classes of middle school students gifted in science, two classes of high school advanced course, and secondary school teachers, were first tested with qualitative questions and four to seven days after they were tested again with quantitative questions. The results are as follows. 1. The majority of the preceding studies have mostly used qualitative patterns patterns to investigate science misconceptions. 2. 8 items of quantitative and qualitative questions for the 1st unit of force and motion presented in the course of the 1st grade of middle school, are developed respectively. 3. The patterns and characteristics of misconceptions found in qualitative questions were similar to those in lots of preceding studies, but the two patterns of qualitative and quantitative items should be fully considered to achieve designed evaluation, for some students and teachers, who think(judge) correctly in qualitative items, showed mis conceptions in quantitative items. And the fact that the rate of correct answer in the qualitative questions was higher than that in the quantitative questions showed that the development of contents in the unit of force and motion in the course of the 1st grade of middle school. 4. Both in qualitative questions and in quantitative questions the rate of correct answer is, on the whole, higher in high school students than in middle school students. 5. Teachers' presumed misconceptions are in much accord with students' misconceptions, but students' misconceptions, which teachers did not presume, were found. Lots of biology and earth-science teachers, who did not major in physics, have misconceptions about physical phenomena, and it is found through this study that teachers are one of the reasons of students' science misconceptions.

In general, due to its intrinsic structural complexities by connecting various structural elements of thin steel, the degradation due to residual stress and welding deformation are almost unavoidable. In addition, the repetitive nature of loading can cause the fatigue crack. In this study, to find optimal shape of scallop, the fatigue tests are performed. The dimensions of connections for longitudinal and transverse ribs are based on the ones applied in Youngjong bridge. Two types of "C type" and "D type" of scallops are used. "C Type" is the same one as recommended in the domestic design specification and "D type" is the one proposed in Europe due to its superiority in the fatigue tests performed. Prior to fatigue tests. numerical structural analyses for those specimens under particular loadings are performed to find tentative stress states of the specimens. Through the fatigue tests, the initial crack and its growth characteristics are analysed and the S-N curves are obtained and fatigue grade is estimated with those.

Background : Bleeding after endoscopic procedure of the stomach carries an increased risk of morbidity and mortality. In case of oozing hemorrhage, not in active hemorrhage, powdered sodium alginate may play a role in control of bleeding with convenience. Therefore, we evaluated the clinical effect and efficacy of sodium alginate powder in upper G-Ⅰ bleeding. Methods : Forty-five patients who had upper G-Ⅰ bleeding after endoscopic procedure were enrolled in this study. Twenty-five patients of them were managed by the application of powder preparation of Sodium alginate(ALTO). The others were observed without treatment. The next day, we performed endoscopy in all patients to ascertain the hemostasis. Results : Of 25 patients managed with Sodium alginate, only two patients(8%) had bleeding (hemostatic rate : 92%), On the other hand, of 20 patients who did not receive any treatment, 3 patient(15%) had bleeding (hemostatic rate : 85%). There was no statistical difference between the two groups(p>0.05). Using other endoscopic procedure, We successfully treated the patient who continued to bleed. Conclusion : We evaluated the effect of the spary of sodium alginate on oozing hemorrhage. Although there was no statistical significance in our study, it seems that the spray of sodium alginate may be a useful method for the prevention of bleeding after endoscopic procedure.
