The purpose of this study was to provide some beneficial information for developing an appropriate school-level curriculum and to acquire some seeential materials for conducting an efficient physical education through some surveys on elementary school student' perceptions of physical education. The 619 elementary school students chosen as sbjects for questionnaires were from twelve different schools and to minimize a statistical aberration sampling was done on a random basis. The survey with thirty-three questions comprise six Subjects: (1) the pbjective, (2)contents, (3) evaluation, (4) educational environment with physical education. The results reflecting frequencies in responses were rearranged into a percentage in terms of each question, sex, region, gender of teachers, instruction type at the schools surveyed. The chi-square test was conducted to check if there were personal differences. The yielded results were as follows. First, the analytical result from the survey on the objective of physical education has revealed that physical education in the emotional and perceptional field is found to be positive, while in the definitive field to be negative. The result from the survey on the contents of physical education shows that the field in which students show the highest interest is "game activities," which are also the field which students want to learn most. Whereas, the field which students find the most difficult turns out to be"representation activities". The survey on the evaluation of physical education yields the result that 37.8% of the students surveyed are in favor of the subjects chosen for evaluation students' practical skills and that 44.9% feel that the amount of their classes is enough for evaluations. It also reveals that 24.9% of the students surveyed feel that they have practiced for evaluations, 60.3% feel that they have enjoyed classes and that 20.8% feel that they are being evaluated in class for a performance evaluation.The survey concerning educational environments show that only 45.4% of the students surveyed feel that equipment used for physical education classes is safe enough, 18,4% of the parents surveyed areinterested in physical education, 13.2% of the physical education classed are replaced by other subjects and that only 42.5% of the schools surveyed have sufficient equipment and tools for physical education.

본 연구는 전환교육의 정책적 지원 방안을 제안하기 위해 수행하였다. 이를 위해 전환교육과 과 관련된 학술대회 발표자료, 연구보고서, 정책회의 자료, 학술 논문 그리고 해외저널 등을 종합 분석하였다. 1차 분석된 자료를 바탕으로 분석의 기본 틀 마련하였고, 이에 따라 분야별 정책 대안을 제시하였다. 그 내용은 전환교육과 관련된 제반 법규의 정비, 포괄적인 측면의 전환모형 정립, 현행 특수학교 직업교육과정의 정비, 평가방법의 구체화, 직업교육 전문 인력의 양성체제 확립, 범정부차원의 전환 교육적 접근, 그리고 다양한 취업활성화 정책 등에 대하여 구체적인 방안을 제시하였다. This study was implemented to propose policy support method about transition education. For this, the related literatures of transition education were analysed to find method about transition education. The suggestion were introduced such as follow category. First, the related laws about transition education should be revised. Second, the system of transition should be changed from narrow transition model to the total approach model. Third, the current vocational special school curriculum have to review to fit the current vocational market and the needs of students. Forth, the evaluation system should be specialized about the method, contents and the ruler of its evaluation. Fifth, the vocational teacher's training system have to improve according to its special area. Finally, the employment policy should be activate to improve chance about getting jobs to students with disabilities.

본 논문에서는 PCM/FM시스템에 대한 비트(bit)오차 확률식을 구하여 이를 수치적으로 계산하여 검토를 행했다. 변조전 필터를 거친 NRZ-L 이진 펄스예을 변조 신호로 하여 반송파를 주파수 변조하였고, 리미터와 변별기를 검출기로 이용하였다. RF 스펙트럼의 제한과 비트 오차 확률의 감소면에서 볼 때, 주파수 편이화 h를 3WT가 되도록 설계하는 것이 적당함을 알 수 있었다. 여기서 W는 변조전 필터의 대역폭이고 T는 한 비트당 시간 간폭이다. The bit error probability of PCM/FM system was derived and numerically calculated. Binary NRZ-L baseband signal was premodulation filtered to frequency modulate a sinusoidal carrier, and a common circuit of limiter-discriminator was employed as a detector. Considering both RF spectrum limitation and bit error Probability reduction, it was found that h ≒ 3WT would be reasonable, where h is the frequency deviation ratio, W is the bandwidth of a premodulation filter and T is the time interval of one bit.

To analyze the skeletal characteristics of the open bite, the faces of normal occlusion and open bite were measured using a cephalogram. The factors which were greatly different from normal occlusion were selected. The effects of these factors on the incisal overbite and correlation on these factors were studied. The following results were obtained: 1. The 13 factors which comprised the characteristics of the open bite were obtained.(Table 5) 2. The cause and amount of the open bite were dependent on the skeletal angulation than skeletal length. 3. For determining the incisal overbite, most highly correlated single factor was the interincisal angle. 4. The correlation on the selected 13 factors which comprised the characteristics of the open bite was obtained.(Table 6) 5. The open bite was due to combination of various factors than due to single factors.(Table 3,4)
