  • Speech material, which is collected from ARS(Automatic Response System), was analyzed and classified into disease and non-disease state. The material include 11 different kinds of diseases. Along with ARS speech, DAT(Digital Audio Tape) speech is collected in parallel to give the bench mark. To analyze speech material, analysis tools, which is developed local laboratory, are used to provide an improved and robust performance to the obtained parameters. To classify speech into disease and non-disease class, multi-layered neural network was used. Three different combinations of 3, 6, 12 parameters are tested to obtain the proper network size and to find the best performance. From the experiment, the classification rate of 92.5% was obtained.

  • This experimental study aims to find out the correlation between semantic predictability and pitch-accent realization. For the experiment, we classified the predictability into three degrees: unpredictable, implicitly predictable, and explicitly predictable. And then each degree divided into to two subcatergories: one is adverbs/adverbial phrases of time or place and the other one is not time or place adverbs/adverbial phrases. The materials used in the experiment were 9 sentences for the each subcategory. One male and one female English native speakers participated in this experiment. Their reading speeches were recorded on Digital Audio Tape. Their speech data were analyzed by using Pitchworks program. The results of this experiment show pitch accented ratio is somewhat in inverse proportion to the degree of predictability.

  • The purpose of this study is to analyze thinking process in problem solving and to get some teaching materials to improve students' problem solving abilities. For this study, 14 girl and boy students in highschool were tested with 7 testing questions. The whole process of students' problem solving was observed by using 'Thinking aloud', recorded by Audio Tape and finally drawn up to Protocol. On the basis of that Protocol, coding system was set up and characteristics of thinking process in each stage were analyzed. -In the stage of planning, successful problem solvers tried to check the properties of words included in problems(Pr) and made it clear that they were seeking(O) -In the stage of planning, students used abstraction strategy(Ab, making equation(E) or using variable(V)) appropriately could solve more difficult problems. Successful problem solvers turned used unsystematical trial into systematical method and were good at using partial objects, assistant factors. - In the stage of carring out the plan, successful problem solvers to reduce the error, check the purpose, used formula, knowledge and calculation. -In the looking back stage, successful problem solvers generalized the answer and checked the total process.

  • 이 연구의 목적은 초임 중등 과학 교사들이 과학 수업에서 학생들의 동기 유발과 학생 이해에 대해서 어떠한 지향을 하고 있으며, 그것이 실제 수업에서 어떻게 실행되고 있는지를 분석하는 것이다. 연구 참여자는 수도권 중 고등학교에서 근무하는 경력 1년 미만의 과학 교사 6명이다. 자료 수집은 수업 관찰 및 녹화, 구조화된 심층 면담과 우선순위 면담, 수업 자료를 통해 이루어졌다. 모든 수업과 면담 자료를 전사한 후, 분석틀에 맞추어 분석하였다. 연구 결과, 초임 과학 교사들은 동기 유발과 학생 이해에 관해 '관리 중심 과학 수업'에서부터 '전통적 과학 수업'까지 지향하고 있었으며, '구성주의적 과학 수업'은 지향하지 못하였다. 지향하는 바를 실행하는데 있어서 한명의 교사는 전문 단계의 실행 수준을 보여주었지만, 나머지 교사들은 초보 단계의 실행을 나타냈다. 본 연구를 통해 과학 교사들에게 동기 유발과 학생 이해에 관한 구성주의적 과학 수업의 방향을 제시해 줄 수 있을 것이다.

  • The purpose of this study is to assess if EMG biofeedback training with progressive muscle relaxation training is effective in reducing the EMG level in patients with tension headaches. This study which lasted from 23 October to 30 December 1989, was conducted on 10 females who were diagnosed as patients with tension headaches and selected from among volunteers at C. University in Seoul. The process of the study was as follows : First, before the treatment the baseline was measured for two weeks and the level of EMG was measured five times in five minutes. And then EMG biofeedback training was used to six weeks, 12 sessions in at and progressive muscle relaxation was done at home by audio tape over eight weeks. Each session was composed of a 5-minute baseline, two 5-minute EMG biofeedback training periods and a 5-minute self-control stage. Each stage was followed by a five minute rest period. So each session took a total of 40 minutes. The EMG level was measured by EMG biofeedback (Autogenic-Cyborg : M 130 EMG module). The results were as follows : 1. The average age of the subjects was 44.1 years and the average history of headache was 10.6 years(range 6 months-20 yens). 2. The level of EMG was lowest between the third and the fourth week of the training except in Cases I and IV. 3. The patients began to show a nonconciliatory attitude at the first session of the fifth week of the training.

  • The purpose of this experimental study is to investigate the relationship between English pronunciation and listening comprehension of English diphthongs and low vowels of Korean college students from the Chungnam and Gyungnam provinces. Of 22 test sentences for listening comprehension, 15 sentences were recorded by native speakers and seven sentences were edited from Springboard by Oxford University Press. For the listening comprehension test, 90 subjects from two groups, Chungnam dialect speakers and Gyungnam dialect speakers, were selected. They listened to 22 sentences produced by audio cassette tape and completed a cloze exercise. By the results of this experiment, we observed that Korean collegians of Gyungnam province showed a better listening comprehension of words including front low vowels when they preceded voiced sounds than those of Chungnam province. When the back low vowel came in an open syllable, we also recognized the same result; Gyungnam province collegians showed better listening comprehension of words including back low vowels than those of Chungnam province. As the results of Hee-Suk Park & Jung-Soak Kim(2003) showed that Gyungnam province collegians pronounced the English low vowels longer than Chungnam province collegians, we discovered that there was a positive relation between English pronunciation and listening comprehension, especially in Gyungnam province collegians. However regarding words including English diphthongs we discovered almost no relation between English pronunciation and listening comprehension.

  • Purpose: This study was to evaluate the effects on the heart rate and respiration rate of preterm infants when providing auditory stimulation on them. Methods: The design of this study was a nonequivalent control group pretest-posttest design in a quasi experimental study. Forty preterm infants were assigned to experimental and control groups : 20 in the auditory and 20 in the control group. The data were collected from May 2014 to October. The auditory stimulation was created by using an audio music tape provided 20-minute per day for 7 consecutive days. In data analysis, SPSS WIN 21.0 program was utilized for descriptive statistics, repeated measurement anova and Mann-Whitney. Results: General characteristics of the two groups showed no significant differences, thus two groups were found to be homogenous. There were no significant differences in heart rate and respiration rate between the auditory and control groups. Conclusion: The effect of auditory stimulation for 7 days was not effective in decreasing heart rate or respiration rate in premature infants. Therefore, the type and length of music therapy must be developed for the improvement of vital signs in preterm infants who were hospitalized in a neonatal intensive care unit.
