Latest modernism shows general idea of phenomenal space through nature of place motility and experience sinceded from standard form and it has general idea of space. therefore this study presents the tension and the relaxation as a method looking for spatal change and value that in spatial experience. For the analysis of work the Conference Pavillon of Tadoa Ando in the furniture company in Vitra Fire Station of Zaha Hidid is analyzed in spatial experence. As the result the result the systematic straight mixture that has a superrimotion with long retangle which the space acts independently and is shown in the drawing of absolutism is formed and collapses theregularity of construction form by decomposition annexation mixing collision and ambivalence. The spatial experiance in this unstable form changes the grade of rank of space by opposite phenomenon by the change of spatial flowing the disorted and vague space that is occurred by superrimotion which has no direction and change of lirht and place and consolidates dynamic strain makes possible to construct against the gravity. And it also creates experienced space thatis reaxed with maintenance of organization of unity harmony, and stsbility.

인터넷의 빠른 성장으로 인해 E-mail은 특정 부류만의 사람이 사용하는 것이 아니라 일반 대중에게도 널리 사용되는 생활의 일부분이 되었다. 현재의 POP3 구조에서느 원격 접속을 시도할 경우 사용자의 ID와 Password는 암호화가 안된 상태로 전송된다. 이러한 것 때문에 여러 보안 공격의 대상이 될 수 있으며 여러 보안 문제를 발생시키고 있다.본 논문에서는 기존의 POP3에서 PASS라는 명령어를 통한 사용자 인증 과정에서 나타나는 무제점을 지적하고 이를 방지하기 위한 새로운 인증방법을 One-Time Password System을 이용해서 제시하고 구현하고자 한다. 또한 One-Time Password System을 이용해 불법적인 방법으로 알아낸 암호의 재사용을 방지했다. 또한 암호화 통신을 위해 관용 암호화 방식의 IDEA 알고리즘을 이용했으며, 키 분배와 관리 문제는 One-Time Password System에서 생성한 키를 IDEA의 비밀키로 사용함으로써 해결했다.

Unlike the extrinsic Modern Functionalist, Louis I. Kahn, a modern American architect, had been pursued intrinsic architectural nature based on historicity; The Essence of Architecture, during his lifetime. That is the reason why he is generally called as one of frontiers toward Post-Modern Architecture. However, the actual meaning of his 'The Essence of Architecture' is so vague and unclear until today, because not only his complex personal thought and career but various and subjective interpretation by so many later architects and architectural theorists. In the context, this paper attempt to reanalyze and clarify Kahn's idea of 'The Essence of Architecture' with the deep and objective view of aesthetics focused on a distinguished contemporary German philosopher, N. Hartman's idea of phenomenological relation and the stratified structure of a work of art.

IT technology based projects was conducted to implement education on producing creative ideas through on-line education and grasp thinking disposition of students in terms of creativity education efficiency. The differences in idea creation among students according to thinking dispositions were analyzed through qualitative evaluation and quantitative evaluation of project and its result was drawn. The purpose of this study was to help cultivate a man of ability who will make a great contribution to knowledge information society by proposing education model based on new method of teaching and learning.
