Many previous studies of data quality have focused on the realization and evaluation of both data value quality and data service quality. These studies revealed that poor data value quality and poor data service quality were caused by poor data structure. In this study we focus on metadata management, namely, data structure quality and introduce the data quality management maturity model as a preferred maturity model. We empirically show that data quality improves as data management matures.

본 논문은 원자력 발전소의 금속파편감시계통(LPMS)에서 충격신호의 탐지를 위해 사용되는 하드웨어 구현에 관한 것이다. 본 논문에서 구현한 것은 LPMS의 하드웨어 중에서 입력된 신호를 디지털로 변환하여 충격신호의 트리거 판단기능을 하는 DAM(Data acquisition module)보드이다. 본 논문에서 구현한 DAM은 디지털 필터와 트리거 판단을 위한 알고리즘이 DSP에서 실시간으로 처리되어 LPMS의 기능을 업그레이드 하였다.

A series of 1,3-dioxoindan-2-carboxylic acid arylamides were synthesized and evaluated for in vitro cytotoxicity against four human cancer cell lines (HOP62, SK-OV-3, MD-MB-468 and T- 47D). The most active was compound 3e (1.2 ${\mu}M$ against SK-OV-3 cell line) bearing a 4- methyl substituent.
