An architectural pre-design, which is conducted prior to the architecture design, supports fundamental configuration during the entire AEC project by predicting the cost, demand, etc., of the building, and is therefore gaining importance. In particular, the massing calculation of the pre-design phase should be prioritized, as it is fundamental to architectural outline. However, most architects depend on only their experience and intuition while conceptualizing an integrated framework of design conditions, including the building code and requirements for the massing calculation of the object. Therefore, many difficulties arise in terms of performing appropriate tasks. Thus, the purpose of this study is to implement a knowledge-based BIM for explicitly representing the design knowledge, which is the basis of decision making for an architect while performing the massing calculation. In particular, the 3D knowledge relevant to a project can be provided and accumulated in the massing calculation by the BIM system; this facilitates an integral understanding. Consequently, the approximate result of massing calculation in 3D BIM environment, through both the knowledge-based BIM template and plug-in, can be swiftly provided to the architect. In addition, the architect can invent various alternatives, estimate resulting costs, and reuse the accumulated knowledge in future BIM design processes.

최근 정보통신 기술의 발달로 통신 시스템의 디지털화, 고속화, 소형 경량화 요구에 따라 통신기기 회로의 설계는 수동소자와 능동소자의 복합 형태를 나타내고 있으며, 정보 통신 기기에서 디지털 신호의 전송속도가 높아짐에 따라 선로의 종류와 특성에 따라 발생하는 누화(Crosstalk)와 상호 결합 등의 문제로 인하여 데이터의 손실 및 왜곡이 발생한다. 이런 문제점을 해석하기 위해서는 전송 선로를 등가적인 회로로 표현하는 것이 필요하며 중요하다. 본 논문에서는 전송 선로의 등가 파라미터를 계산하기 위해 모멘트법을 이용하여 단층 및 다층 구조의 마이크로 스트립 선로에 대한 해석 결과를 비교하여 나타낸다.
