Choral activity plays very important part in the music education. It teaches the development of vocalization, ear-training, sight-singing and cooperative spirit with the sense of harmony. It also helps the growth of abilities to express muisical beauty and improve the harmonic sense. This study analyses the choral education content in eight different music texbooks used in high school and poses questions to the music teacher in hope of improving choral teaching. Question to the music teachers are summarized as follows; 1. The Questionaire seeks teacher's opinions regarding the weight of choral music in high school music textbooks. 2. The questionaire finds out how many credit hours are given for choral music in one music class hour. 3. The Questionaire finds out of the school supports choral activity, the choral class enrollment, rehearsal schedule and how the choral group was organized. 4. The Questionaire finds out the number of schools have held choral competition, and how much interest the teachers and students have. The result of these questions reveal several aspects. The answers have shown a big difference between Taegu and Kyungbook Province. And some of the answers agree with each other. Finally, the most important ways, to improve the high school choral education are for the teacher's concern, the realization of its important contribution and the full participation of students in the choral program.

Personal computer-based data acquisition system designed to perform elctrical transport characterization of high-Tc superconductors is presented. This system can measure the temperature dependence of the resistance. Four point ac method is adoped to eliminate the effects of contact resistance and thermal volatge. The temperature is measured by copper-constantan thermocouple with resolution and accuracy of 0.1 K and ± 0.6 K, respectively, which are the limit of c-c couple. And method of couple-EMF to temperature converting is presented. The system can be easily modified to measure the critical current of the superconductor.
