일본의 공업고등학교 졸업생들은자신의 전공 영역에서는 충분한 기능을 보여줄 수 있을지라도 국립대학 입학을 위한 시험을 통과하기에는 어려운 실정이다. Niigata대학, Nagasaki 대학 그리고 Toyama 대학의 공학부 교수들은 대학 입학 시험을 위한 과제를 마련하기 위하여 1994년부터 공동으로 노력을 기울이고 있으며, 학생들의 교육적 배경과 필요에 부합하는 일반 교육과정을 설치하고 보충수업을 제공하고 있다. 이러한 프로젝트가 공식적으로는 1999년 종료되었지만 Niigata 대학에서 계속적으로 진행되고 있다. While graduates of Japan's technical high schools might demonstrate skills in a given specialty, they would be hard-pressed in any attempt to pass national universities' notorious entrance examinations. In a collaborative effort begun in 1994, the faculties of engineering at Niigata, Nagasaki, and Toyama Universities set about the task of preparing entrance examinations, and a general curriculum geared to the needs and educational backgrounds of these students, offering them supplementary lessons. While the larger project officially ended in 1999, we are carrying the research forward in Niigata University.

A feasibility study on the seismic design of nuclear reactor buildings with application of a seismic isolation system is introduced. After the Hyogo-ken Nanbu earthquake in Japan of 1995, seismic isolation technologies have been widely employed for commercial buildings. Having become a mature technology, seismic isolation systems can be applied to NPP facilities in areas of high seismicity. Two reactor buildings are discussed, representing the PWR and BWR buildings in Japan, and the application of seismic isolation systems is discussed. The isolation system employing rubber bearings with a lead plug positioned (LRB) is examined. Through a series of seismic response analyses using the so-named standard design earthquake motions covering the design basis earthquake motions obtained for NPP sites in Japan, the responses of the seismic isolated reactor buildings are evaluated. It is revealed that for the building structures examined herein: (1) the responses of both isolated buildings and isolating LRBs fulfill the specified design criteria; (2) the responses obtained for the isolating LRBs first reach the ultimate condition when intensity of motion is 2.0 to 2.5 times as large as that of the design-basis; and (3) the responses of isolated reactor building fall below the range of the prescribed criteria.
