Today, people are bombarded with information, high-technology and multimedia. With that in mind, museum can no longer attract visitor with traditional concept, so it must find some solution or stimulation to attract their attention back. New museum is becoming a experimental space for new culture, new education, and most of all a place to fulfill one's satisfaction of life. Over the past centuries, Guggenheim Foundation has done a great job in providing place for art and place to get emotional stimulation. Out of all of their museums, Frank L. Wright's Solomon R. Guggenheim in New York and frank O. Gehry's Guggenheim Museum in Bilbao had most unique character yet share similar feature to be recognized as the architectural landmark of the 20th & 21st century Although there are close to 50 years of gap between two museums, their unique, attractive, site-specific, emotional value comes from the two most innovative architect of the past and present century. For Wright the Guggenheim was his last project but it had one of the greatest impact on his career and for Gehry the museum gave him confidence that anything is possible. This study will focus on the spatial organization as well as the architectural formation of both museum to compare and analyze. The goal of the research is to give fundamental data which will reveal emotional elements as well as concepts from each work. The content of this research will mainly focused on their architectural philosophy and it will reveal their concept on human emotion as well as the characteristics of the spatial organization. The result of the study will be a valuable reference for people designing art & cultural facilities in the future.

최근 많은 도시는 기존의 이미지에서 벗어나 국가 경쟁력을 높이기 위한 수단으로 도시재생에 주목하고 있다. 그중 미술관과 박물관을 활용한 문화기반형 도시재생이 주목받고 있으며, 산업화시대 이후 낙후된 스페인의 도시 빌바오에 세계적인 브랜드인 구겐하임 미술관을 개관하여 지역에 경제적 성과를 안겨준 구겐하임 빌바오가 성공적인 사례로 꼽힌다. 많은 도시가 이를 벤치마킹하여 미술관건립을 도시재생의 수단으로 추진하고 있으며, 석유생산이 주산업이었던 중동의 아랍에미리트(UAE) 또한 1970년 이후로 포스트-오일(post-oil)시대에 대비하여 경제기반을 석유부문에서 지식기반산업 육성으로 이동하기 시작하면서 미술관을 활용한 도시재생에 주목하고 있다. 아랍에미리트의 수도인 아부다비(Abu Dhabi)는 2008년 '경제비전 2030' 발표를 통해 문화 관광 분야 발전에 주력하면서 사디야트(Saadiyat) 섬에 다수의 미술관과 박물관 건립을 추진 중이다. 구겐하임 빌바오와 동일 건축가인 프랑크 게리(Frank Gehry)에게 의뢰하여 최대 규모의 구겐하임 미술관을 아부다비에 설립하려는 계획도 중동지역 현대미술의 중심역할을 목표로 2012년에 개관을 계획하고 있었다. 그러나 그동안 여러 차례 건설이 중단되는 등 난항을 겪고 있으며, 지역 특유의 사회적 문화적 문제들과 대면하면서 현재도 개관 시점이 불투명한 상태이다. 본 논문은 세계적인 구겐하임 미술관이 글로벌 전략 일부로서 아부다비로의 확장과정에 대해 살펴보면서, 빌바오와는 또 다른 지역적 환경맥락에 기인한 문제점들에 대해 논하고자 한다. 결국 막대한 자본을 바탕으로 한 중동지역에서의 문화 주도형 신도시건설은, 지역의 사회적 문화적 발전을 통해 성숙한 문화생태계 성립과 수반되어야 함을 보여준다.

Isopropanol 용매 내에서 titanium isopropoxide($Ti(O-^iPr)_4$)의 가수분해반응에 의하여 $TiO_2$ 미분말을 합성하였고 가수분해 반응 속도를 자외선분광법에 의하여 측정하였다. 반응은 $Ti(O-^iPr)_4$의 농도에 비하여 물 농도를 크게 하여 유사일차반응으로 진행시켰고, 물 농도 및 온도의 변화에 따른 반응속도상수를 Guggenheim method로 계산하였다. 또한 물의 동위원소 효과를 측정하여 반응에 참여하는 물분자의 촉매성을 확인하였다. 입도분석과 미세구조 관찰 결과, 얻어진 $TiO_2$ 미분말은 $0.3{\mu}m$정도의 입자크기를 갖는 구형의 입자로 확인되었다. 또한 반응속도로부터 전이상태에 참여하는 n value와 열역학적 파라메타를 계산한 결과, $Ti(O-^iPr)_4$의 가수분해반응은 이분자 반응인 $S_N2$ mechanism으로 진행하는 것으로 추정되었다.

Starting from Guggenheim Bilbao Museum in 1997, it has been increased steadily that complex geometry buildings using digital designs and construction process. Since 2010, the domestic Freeform design has been widely used for buildings such as Dongdaemoon Design Plaza, Seoul City Hall, Tri-Bowl, and etc. But there are many defects such as the increased cost and period of construction, and the declined quality of construction because of the lack of optimized method and engineering experiences. Therefore, this study has an effort to review case study of the recent freeform buildings and construction methods using digital fabrications. And this study proposed the improve method for the construction quality for freeform buildings.

This study is about interdisciplinary education model of using Davis Guggenheim's documentary film on global warming which is a big concern in climate change issues, An Inconvenient Truth. It based on Al Gore's slide speech. Through a course student analyzed the cause and phenomenon of global warming resulted from increase of $CO_2$ by using fossil fuel and its environmental science effects-heat wave, desertification, tornado, hurricane, sea level rise caused by melting glaciers, destroying ecosystem like habitat degradation of wild animals, for example polar bear, extreme cold wave caused by change of ocean currents- of global warming. After, student discussed of efforts to prevent global warming. This educational model is appropriate for lower grade student of environmental engineering and also available for converged majors or general education class.

An approximate molecular theory of classical fluids based on the nonrandom lattice statistical-mechanical theory is presented. To obtain configurational Helmholtz free energy and equation of state (EOS), the lattice-hole theory of the Guggenheim combinatorics is approximated by introducing the nonrandom two-fluid theory. The approximate nature in the derivation makes the model possible to unify the classical lattice-hole theory and to describe correctly the configurational properties of real fluids including macromolecules. The theory requires only two molecular parameters for a pure fluid. Results obtained to date have demonstrated that the model correlates quantitatively the first- and second-order thermodynamic properties of real fluids. The basic simplicity of the model can readily be generalized to multicomponent systems. The model is especially relevant to (multi) phase equilibria of systems containing molecularly complex species.

n-propanol 용매내에서 titanium n-propoxide($Ti(O^nPr)_4$)의 가수분해반응에 의하여 $TiO_2$ 미분말을 합성하였고, 가수분해속도를 자외선 분광법에 의하여 측정하였다. 분말합성은 water/alkoxide의 농도비가 약 300정도에서 실시하였으며, 물농도, 반응온도, 반응시간 및 반응용액의 산 염기효과에 의한 합성조건을 조사하였다. 반응은 $Ti(O^nPr)_4$의 농도에 비하여 물농도를 과량으로 하여 유사일차반응으로 진행시켰고, 반응속도상수를 Guggenheim method로 계산하였다. 또한 물의 동위원소효과($D_2O$)를 측정하여 반응에 관여하는 물분자의 촉매성을 확인하였다. 실험결과 중성 및 염기성 용액 조건에서 $TiO_2$미분말이 합성되었고, 미세구조 관찰로부터 $TiO_2$입자는 직경 $0.4-0.7{\mu}m$ 정도의 구형입자로 확인되었으며, 물의 농도와 반응온도가 증가할수록, 반응시간이 감소할수록 입자크기는 작아지는 경향을 보였다. 물의 동위원소효과로부터, 물분자는 nucleophilic catalysis로 작용하고 있으며, 반응속도로부터 전이상태에 참여하는 n-value와 열역학적 파라미터를 계산한 결과, $Ti(O^nPr)_4$의 가수분해반응은 이분자 반응인 associative $S_N2$ mechanism으로 진행하는 것으로 추정되었다.

Carboxylated multi-wall carbon nanotubes (MWCNTs-COOH) have been used as efficient adsorbents for the removal of picric acid from aqueous solutions under stirring and ultrasound conditions. Batch experiments were conducted to study the influence of the different parameters such as pH, amount of adsorbents, contact time and concentration of picric acid on the adsorption process. The kinetic data were fitted with pseudo-first order, pseudo-second-order, Elovich and intra-particle diffusion models. The kinetic studies were well described by the pseudo-second-order kinetic model for both methods. In addition, the adsorption isotherms of picric acid from aqueous solutions on the MWCNTs were investigated using six two-parameter models (Langmuir, Freundlich, Tempkin, Halsey, Harkins-Jura, Fowler-Guggenheim), four three-parameter models (Redlich-Peterson, Khan, Radke-Prausnitz, and Toth), two four-parameter equations (Fritz-Schlunder and Baudu) and one five-parameter equation (Fritz-Schlunder). Three error analysis methods, correlation coefficient, chi-square test and average relative errors, were applied to determine the best fit isotherm. The error analysis showed that the models with more than two parameters better described the picric acid sorption data compared to the two-parameter models. In particular, the Baudu equation provided the best model for the picric acid sorption data for both methods.

Sliced and whole root of rehmannia were dehydrated in a laboratory dryer at 40, 60, 80, and $100^{\circ}C$ to evaluate the kinetic parameters for dehydration of rehmannia. The drying curves of both samples were characterized by a falling-rate drying period only. Sliced rehmannia dried 1.1 to 3.1 times faster than whole root of rehmannia depending on drying temperature. Equilibrium moisture content (EMC) of rehmannia samples at the drying temperature tested were 0.069-0.078 g water/g dry solid, which was coincided with the monolayer moisture content (0.06 and 0.07 g water/g dry solid) evaluated from desorption isotherms using GAB (Guggenheim-Anderson-de Boer) model. A logarithmic model for thin layer drying was applied to evaluate the drying time to reach EMC ($t_{EMC}$) and drying constant (k). The effect of temperature on $1/t_{EMC}$ and k was described by the Arrhenius model with activation energy values of 32.56 and 47.14 kJ/mol determined using the former parameter, and 34.27 and 38.26 kJ/mol determined using the latter parameter for sliced and whole root of rehmannia, respectively.
