건설현장에서 발생하는 중대재해에서 한 건에 여러 명의 사상자를 내는 대표적인 재해는 콘크리트 타설공사중 발생하는 붕괴재해이다. 특히, 가설기자재 성능검정규격이 정해지지 않은 6m 파이프써포트는 비검정품으로써 생산 및 사용이 금지되어 있는 가설재이지만, 체육관ㆍ상수도 배수지공사ㆍ건축물의 지하진입로 등에서 주로 사용되고 있으며, 이들을 사용한 콘크리트 타설작업에서 중대재해가 발생하는 경우가 많다.(중략)

다양한 지형공간과 시설물이 공존하는 대학캠퍼스를 입체적으로 보여주고 그 시설물을 관리하기 위해서는 2차원 평면적 요소와 결합된 3차원 이상의 공간정보의 생성은 매우 중요한 캠퍼스 관리의 선택요소로 등장하고 있다. 이를 위하여 현재 사용가능한 지형도와 시설도 및 영상자료를 정확한 위치정보로 추출 또는 변환하여 지형공간 내에 존재하는 도로, 건물, 기타 시설물을 입체적으로 중첩함으로서 3차원 이상의 입체적 효과는 물론 부분적으로는 이동접근이 가능한 시뮬레이션 작업을 적용하였다.

We compared the cognitions of students, faculty, and business leaders in engineering related to woman employment and successful career. For this research, we developed questionnaires for 240 students of Korea National University of Transportation and Korea National University of Education, and 8 faculty who taught the students in the improvement program of engineering education environment for gender sensitivity, and 28 business leaders of company located in Chungbuk. As results, there were lots of difference among the cognitions of students, faculty, and the leaders related to woman employment and successful career. Especially, leaders gave considerable thought to upright character and affective capacity when they select employees. Therefore, we need to concentrate efforts to bring up talent women whom companies prefer by strengthening the strength and make up for the weakness as women in the improvement program of engineering education environment for gender sensitivity.

The temple Hoeamsa(檜巖寺) was repaired by Naong(懶翁), and with this the power of the temple became far greater to be the greatest Buddhist temple during late Goryeo and early Joseon. Naong's reconstruction of Hoeamsa was originated from Jigong(指空)'s teaching 'Samsan Yangsu(三山兩水)'. But it is not clear whether Samsan Yangsu really meant Hoeamsa. By the way, after 14 years, Naong suddenly remembered this word and began to repair Hoeamsa in a large scale. From this, we can guess that Naong tried to give the contemporary Buddhism some change through the repair of Hoeamsa. But, as King Gongmin(恭愍王) the greatest supporter of Naong was suddenly assassinated, the political situation changed a lot and Naong also died unexpectedly. Naong's death brought out the critical sense to Hoeamsa and, in the process to resolve the crisis, the repair of Hoeamsa began to be justified through diverse religious factors. As these were expanded and developed on and one, Hoeamsa came to be honored as the most divine temple in Korea during the early Joseon dynasty. Furthermore, into the cause structure for the Naong's repair of Hoeamsa, the influence of Jajang was added through Odaesan Buddhism. As we can well understand, late Silla situation of Jajang and the late Goryeo of Naong were very similar and the both Buddhist leaders should have derived out some religious solution for them. In other words, both of them had a similar recognition in finding the religious solution for the contemporary crises. It becomes a way to understand the Hoeamsa repairing structure taken by Naong and his disciples. Therefore, by comparing the similar religious solution structures given by Jajang and Naong and by clearer understanding on Samsan Yangsu spirit, we can see the repair of Hoeamsa and the related aspects more accurately.

지형공간에 대한 3차원 이상의 입체적인 지공간에 대한 시각화와 더불어 시시각각으로 변화하는 지형공간을 유지하기 위해서는 시공간에 존재하는 정부의 취득과 표현기법이 신속하고 다양한 정보의 분석과 정리가 필수적인 숙제로 인식되어가고 있다. 렬 연구에서는 농촌 및 산촌지역을 대상으로 수집한 위성영상과 국립지리원에서 제작한 수치지도를 이용해 정밀지형보정을 실시하고 DEM과 정사영상을 이용해 3차원 이상의 다차원적인 공간정보시뮬레이션을 제작한 것이다. 이러한 입체적인 조감도의 작성기술은 각 분야에서 널리 활용될 수 있는 매우 중요한 요소기술로 활용될 수 있어, 위성영상을 이용하여 기존의 수치지형도와의 결합을 통한 3차원 영상 지도의 제작을 시도하여 다차원적인 분석이 가능한 입체 영상 조감도를 작성하였으며, 비행 시뮬레이션 기법에 의한 가상적인 접근이 가능한 연구결과를 얻어냄으로써 지형공간정보의 고부가 콘텐츠 활용을 유도하도록 하였다.

The Bieniawski's geomechanics classification system(1984) is widely employed as a tool of engineering evaluation of rock masses for tunnel design. Since the siz parameters adoped in the system are believed to control the engineering behavior of rock mass under an external load, no question may be raised to the conceptional idea immanent in the system. However, the rating grade for each individual parameter given in the system may be properly measured since an engineering property of rock mass is not stepwise changed but continuously changed. In order to get the proper rating grade based upon the continuously changed properties in each parameter, several equations presented in this paper are obtained through regration analyses with the grades and median values of properties givne in the system. A FORTRAN computer program given in the paper could provide not only RMR value but also rock mass properties (E, c, o, v, etc.) using the empirical equations.

Crystalline carbon nitride films have been deposited by RF reactive magnetron sputtering system with negative DC bias. The carbon nitride films deposited on various substrates showed ${\alpha}$- C$_3$N$_4$,${\beta}$-C$_3$N$_4$ and lonsdaleite structures through XRD and FTIR We can find the grain growth of hexagonal structure from SEMI photographs, which is coincident with the theoretical carbon nitride unit cell. When nitrogen gas ratio is 70 % and RF power is 200 W, the growth rate of carbon nitride film on quartz substrate is about 2.1 $\mu\textrm{m}$/hr.

격자전극을 가진 질화탄소막을 이용하여 새로운 습도센서를 개발하였다. 결정성 질화탄소막의 감습 특성을 조사하고, 광범위한 상대습도($10%\sim90%$)에 대해 민감한 임피던스와 커패시턴스 의존도를 보였다. 특히 격자전극은 습기의 자유로운 흡 탈착을 용이 하게 하여 센서의 히스테리시스를 줄였다. 또한, 질화탄소막은 물리, 화학적으로 안정한 물질이므로 고온, 고습 및 화학적으로 열악한 환경 속에서도 뛰어난 특성 을 나타내었다.
