The conceptual design evaluation of Deep-Sea Manganese Nodule Miner(DSNM) based on Axiomatic Design was preformed. Functional Requirements(FRs) in functional domain and Design Parameters(DPs) in physical domain were embodied for the given concept design of DSNM. Interactions between FRs and DPs were sequentially analyzed from the first level hierarchy to the lower level hierarchy. The interactions were expressed as design matrices which showed the dependence or independence between FRs and DPs. The results showed that the design of DSNM was not a coupled one, but a decoupled. Finally, it was conceptually verified that DSNM was a good design satisfying the independence axiom of the Axiomatic Design. 심해저 망간단괴 집광시스템(이하, 집광시스템)의 개념설계가 공리적 설계(Axiomatic Design)의 관점에서 평가되었다. 또한 이미 수행된 집광시스템의 개념설계에 대해 기능적 영역의 기능요구와 물리적 영역의 설계파라미터가 구체화되었다. 기능요구와 설계파라미터의 상호관계는 첫 번째 수준 계층에서 하위 수준 계층으로 순차적으로 분석되었다. 이러한 상호관계는 설계행렬의 형태로 표현되었고 기능요구와 설계파라미터 사이의 독립성을 판단하기 위한 지표로 사용되었다. 설계행렬의 분석결과 본 집광시스템은 설계파라미터간에 연성이 되지 않는 비연성화된 설계임이 확인되었다. 결과적으로, 본 집광시스템은 독립공리(Independence Axiom)를 만족하는 잘된 설계임이 개념적으로 입증되었다.

Soil dust emitted from large scale construction sites in urban areas has posed a significant health threats to local residentsby exacerbating air quality. Water-spraying (moistening) is commonly practiced to lower the dust emission in constructionsites, but its long term effectiveness is highly questionable. In this study, the utility of starch and PVA(polyvinyl alcohol)was investigated in suppression of the soil dust emissions in construction sites in Seoul areas. The efficiency of the twosuppressants was tested with test soil sample in a lab-scale wind tunnel box under different concentrations of suppressantsand soil textures. Starch and PVA showed the superior ability to suppress soil dust emission as compared to moistening,resulting in PM10 and PM2.5 lower than the daily limit values of 30 and 15 μg/m3, respectively. PVA showed highersuppression capability than starch for all conditions. The test soils mixed with suppressants also showed dramaticallyenhanced aggregate stability compared to the non-treated soil.
