Modernism in architecture is a very complex and contradictory phenomena. So much so that it has been defined in various ways throughout the history, depending on one's position in the cultural and historical circumstances. It is thus necessary to map out the various concepts of modernism and their relationships in order to have a more comprehensive understanding of modern architecture. This paper attempts to define the various positions as functionalism, formalism and artistic avant-gardism, and to trace their history from the early twentieth century to the present. The change of the concept of modernism from functionalism to artistic avant-gardism seems a logical process in the history of western modem culture. The tendency of contemporary architecture to be more abstract and self referential artistic practice reflects the fragmentation of modern culture and the separation of art and technology. The validity of this position, of course, depends on how one evaluates the role of modern art in the situation of modern culture. It could be viewed either negatively or positively. However, this position is problematic in that it disregards the fundamental differences between architecture and other arts and distanced architecture farther from its material base. Given this historical perspective on the concept of modernism, modernism in Korea should not viewed simply identical to the western modernism, nor should western modernism be imported uncritically. The characteristics of her modernization and their differences from the west should be considered, along with the different status and role of architecture in korean modern society.
새로운 분리공정으로서 Membrane Distillation(MD)에 대하여 고찰하였다. 정밀여과에서 이용되고 있는 소수성막이 MD공정에 적합한 막소재가 된다. MD는 고온보다는 완화된 온도에서 100%에 가까운 선택도를 가지면서 기존의 수처리 공정을 간소화시킬 수 있는 가능성이 있다. MD는 막표면의 기공에서 층기-액체간의 상분리가 일어나는 분리원리를 이용한다. 공급액 및 투과액의 온도, 조성, 막의 젖음현상, 열 및 물질전달이 MD의 선택도와 플럭스를 결정할 수 있다.
