공간구문론을 이용한 자하 하디드 뮤지엄 건축의 공간구조 분석

With the rising demand for urban landmark building structures, freeform architectures have ever increased rapidly. Such architectural freeform represents technological and economic superiority and at the same time, socio-cultural context, functioning as a yardstick to gauge a country’s or a city’s technological, cultural and economic levels. This trend is also witnessed in South Korea as well. One good example is the Dongdaemun Design Plaza. The construction is the largest 3-dimensional irregular architectural form of South Korea, which is currently under multiple controversies before its completion in July 2013. Zaha Hadid, architect who designed the Dongdaemun Design Plaza, was initially called as an architect without an architecture or a paper architect for his presentation of intuitive and informally connected building designs. Hadid had no constructed building structure of her for some time but as she became the first female Pritzker Architectural Prize in 2004 and joined the ranks of global leading architects, she has enjoyed broad popularity for her cultural building structures in the market. And lots of her works have won many international architectural design contests. This study sought to examine the characteristics of internal space of Zaha Hadid’s construction with flexible exterior appearances. To this end, we employed the Space Syntax theory, an analytical method describing the typologic association between spaces in a qualitative way. For the purpose of this research,

Buildings of the de-constructive tendency beyond definite forms are being constructed in countries with economic power, technical skills and open culture because they require social conditions to accommodate those buildings as well as a lot of construction expenses. Frank Gehry and Zaha Hadid can be chosen as the representative architects of de-constructivism series who are currently working hard. Though both of them are architects belonging to the de-constructivism category, their works show different construction due to the differences in architectural philosophy and working ways. Gehry consider Architect as a fine art and enjoy (sculpture) three-dimensional structure work through Rough Model. With increasing demand for landmark atypical buildings, Hadid has been frequently awarded in the recent series of International Competitions and deals with a lot of cultural works. Affected by absolutism, Hadid showed various diagonal lines in her early construction and works based on the theme of dynamics such as lightness, gliding and light contact with the ground etc. Hadid"s Architecture which worked under the theme of dynamic contains a variety of diagonal lines that might cause the viewers to have difficulty on spatial awareness, thus It is known that Hadid"s Architecture has lower efficiency on the Circulation and difficulty on spatial cognition compared to the typical museum. According to the research findings of the previous paper that space understanding of viewers on Frank Gehry Museum consisting of complicated planes is generally better than that of them on a typical museum, the purpose of this study is to find out the Circulation efficiency and spatial cognition of Hadid Museum by explaining the space structure of dynamic Hadid Museum and the difference compared to typical museum.

The effects of alloying elements on the superplastic properties of Al-Li based alloys had been investigated. The intermediate thermo-mechanical treated(ITMT) Al-2.0wt%Li, Al-2.0wt%Li-1.0wt%Mg, Al-2.0wt%Li-0.12wt%Zr and Al-2.0wt%Li-1.2wt%Cu-1.0wt%Mg-0.12wt%Zr alloys were tested in tension at various temperature (400, 450, 500 and 550℃) and strain rate(6.7×10^(-3), 1.0×10^(-2), 1.6×10^(-2) and 5.0×10^(-2)/sec). The results were as follows : The superplasticity in binary, ternary and pentanary alloys appeared at 500 to 550℃, and good strain rate for superplasticity, 1.6×10^(-2)/sec∼1.0×10^(-2)/sec for a binary alloy and 1.0×10(-2)/sec∼6.7×10^(-3)/sec for ternary and pentanary alloys. A Zr-added ternary alloy had best value of elongation (730%) in four alloys at 550℃ of tension temperature and 1.0×10^(-2)/sec of strain rate. The strain rate was greatly dependent on tension temperature and true strain rate was more than 1.0 at all test temperature and strain rate. In binary and Mg-added teranry alloys, the necks were slightly formed and their fracture surface had lips shape, but Zr-added ternary and pentanary alloy fractured along the grain boundary without necking. Their dislocations moved to grain boundary during superplasticity deformation and arranged perpendicular to grain boundary. Superplastic deformation was made by grain boundary slip of dislocation slip creep and model of core and mantle.

본 연구의 목적은 cardiac MRI를 이용하여 확장기와 수축기의 정량적 측정을 통해 각 단면의 심박출률의 차이를 알아보고자 하였다. 총 12명(정상 7명, 심근교 1명, 부정맥 4명)을 대상으로 심첨에서부터 대동맥궁 쪽으로 단면을 얻었다. 수축기와 확장기 영상을 확대하여 경계를 정하였고, 이 면적을 바탕으로 1, 3, 5, 6-7단면의 심박출률을 구하였다. 정상인의 평균 박출률은 각각 1, 3, 5, 6-7단면에서 67.14%, 66.24%, 65.63%, 그리고 65.29% 로 나타났다. 반면. 환자들의 평균 박출률은 각각 1, 3, 5, 6-7단면에서 61.74%, 60.92%, 60.89%, 그리고 61.89%로 나타났다. 본 연구를 통해 cardiac MRI를 이용한 특정단면의 심박출률은 각 단면마다 큰 차이가 없음을 알 수 있었고 따라서 cardic MRI를 이용한 심박출계수의 평가는 대표 단면만으로 가능함을 알 수 있었다. The aim of this study is to evaluate the differences of ejection fraction of left ventricle through the quantitative analysis of diastolic and systolic volumes according to slices selected using cardiac MR imaging. A total of 12 volunteers (7 normal, 1 myocardium bridge, and 4 arrhythmia) underwent cardiac MRI on a MR scanner(Magnetom Trio, Siemens, Germany). Ejection fractions for quantitative analysis were calculated at single slice of center of left ventricle, 3, 5, and 6-7 slices extending from the center of left ventricle. Average values were analyzed for evaluating differences of ejection fraction according to the number of slices selected. Mean value of normal person of ejection fraction were 67.14% at single slice of center of left ventricle, 66.24% at 3 slices, 65.63% at 5 slices, and 65.29% at 6-7 slices. While ejection fraction obtained from a patient with 61.74% at single slice of center of left ventricle, 60.92% at 3 slices, 60.89% at 5 slices, and 61.89% at 6-7 slices. There was no significant differences by the number of slices selected. This study demonstrates that ejection fraction obtained from single slice of center of left ventricle may represent a optimum parameter for cardiac function, instead of the value calculated on the variable slices selected.
