콘크리트 구조물이 대형화됨에 따라 설계단면이 증대되어 상대적으로 많은 경제적 손실을 부담하게 된다. 따라서 단면을 감소시키면서도 소요의 하중에 안전한 구조물을 건설하기 위해서는 우선적으로 구조물 건설에 기초가 되는 고품질, 고내구성의 고강도 콘크리트 개발이 절실히 요구된다 본 연구에서는 일정 시멘트비 및 혼화재 비율하에서 소요의 워커빌리티가 확보되는 고강도 콘크리트를 시간과 온도의 변화에 따라 증기 양생하여, 압축, 인장, 휨강도 뿐만 아니라 파괴특성을 실험적으로 연구하였다. 시료 제작시 시멘트 입자 사이의 공극 및 불연속 영역을 충전하여 고밀도화하기 위한 콘크리트용 혼화재로 시멘트 비표면적이 상당히 작은 초미립 분말인 실리카흄을 이용하였다. 또한 AE감수제 및 고성능 유동화제를 사용하여 혼화재의 첨가에 의하여 발생될 수 있는 워커빌리티의 감소를 방지하였다. 실험결과에 의하면 일정 양생 지속 시간하에서 온도의 증가에 따라 콘크리트의 압축, 인장 및 휨강도가 전반적으로 증가하였다. 동일하게 일정 온도하에서 양생 지속시간이 커짐에 따라 강도들이 증가됨을 알 수 있었다. 따라서 상대적으로 높은 온도와 긴 지속 양생 조건하에서 파괴에 대한 저항력이 크게 나타났다. The compressible, tensible, and flexibleresistance of the high strength concrete is analyzed by the experimentation in the present study. For the test, we cure several samples with the silica fume as a mixture being become dense the spaces between the particle of cement under the variation of both the temperature and the curing-interval. Then, the superplasticizer and the ezcon are also used to satisfy the required workability for construction. The compressible, tensible, and flexible resistances to a stress are increased as increasing the temperature and the time interval for the curing. Therefore it is concluded that the overal fractural and mechanical properties is improved by mixing the silica fume into the cement.

Fe₂O₃-TiO₂artificial passive films were formed at the temperatures of 200-350℃ by low pressure MOCVD technique. The relationship between the formation temperature and corrosion resistance of the Fe₂O₃-TiO₂films was examined in acid solutions. Fe₂O₃-TiO₂films deposited above 300℃ were crystalline and the films deposited below 250℃ were amorphous. The dissolution rate of the Fe₂O₃-TiO₂films deposited at 200 and 250℃ decreased with increasing the formation temperature in 5 M HCl, but the films deposited at 300 and 350℃ hardly dissolved in the solution. The films deposited at 200 and 350℃ easily dissolved at cathodic potentials in 1 M H₂SO₄and HCl owing to te selective reduction of iron oxide components in the films. But, the selective reduction in the films deposited at 300 and 350℃ was suppressed. The Fe₂O₃-TiO₂films deposited above 300℃ have higher corrosion resistance than that of the films deposited below 250℃, because the former have high crystallinity and cotain high chemical resistant oxides.

Average-current mode controlled boost rectifier is most universally used at present, While the method gives high power factor, low harmonics distortion, has drawbacks such as 3-feedback loop, complex component, difficulty of control-circuit design, and high cost. Research for improving these problem has been carried out, and Nonlinear Carrier(NLC) Control method is representative. This control method has easy algorithm for control, and its feedback loop and control components are reduced. In this paper, the control method was evaluated by simulation through Matlab/Simulink, and experimented with 550W boost rectifier. As the result, that can get high power factor above 0.95 and low harmonic distortion was confirmed. Also, a good dynamic response on line and load variation was confirmed.

김제홍 건국대학교 1996 대학원 학술논문집 Vol.43 No.-

The investment of CIM(Computer Integrated Manufacturing) will be reasonably selected according to the knowledge of each effective factor. Determination of configuration and selection of the management investment to be considered is very importent issue in the CIM. The property of CIM is classified into quality, reliability, flexibility and productivity. The object matrices are used for evaluation of each factor. In general, the evaluation of CIM is either quantitative or qualitative. The former has the limitation by a factor of being hard a measure for data and the latter has a shortcoming of being impossible to gain an objective judgement. Moreover, proper measurement of each factor is not easy because its scale and expective effect are so bulky. This study is concerned with the economy of the CIM. Therefore this study presents the method for evaluation in the case when the attribute is either quantitative or qualtative.

Korea has the ground which freezes in winter and melts in warmer seasons by turns. Therefore, in designing civil-structures or buildings on such ground, the depth of seasonal frost penetration must be considered. In this paper, approximate contours of the maximum depth of frost penetration in Korea is presented. The National Construction Research Institute of Korea has measured the depth of the frozen ground covering all the area of South Korea during the ten years ranging through 1980. The measurement were made for the frozen ground at random but intended for the most frost-susceptible soils. The contour of the maximum depth of the frost penetration is drawn on a map with data collected during the ten years. It is known that the maximum depth of the frost penetration is related to freeze index values. An empirical formula expressing the relation is suggested, in which the depth is proportional to the one-fifth power of the air freezing index values.
