  • Architecture and Fashion mutually affects the shape and appearance of the other as an art of space according to the hybrid trends. Therefore, the purpose of this study is to find the correlations between the characteristics of traditional architecture types in Southeast Asia and modern fashion. Firstly, characteristics of the types obtained through the theoretical consideration of Southeast Asian architectural tradition include vertical, symmetrical, geometrical, epeated and continual structure. On the basis of these characteristics analyzed from 2013's S/S to 2015's F/W collection of Alexander McQueen, Gareth Pugh, Victor & Rolf, designers with strong creative and experimental minds who juxtaposed designs of two opposing points as well as hybrids since 2000, the following formativeness exists. First, the vertical structure of high floor is represented as a straight silhouette, a color contrast, vertical cut or wrinkle. Hence, it impresses verticality, rhythm, etc. Second, symmetrical structure of the gable roof is represented as a trapezoidal shape starting from the shoulder line or neck line widened into sleeves, impressing symmetry, dynamism, etc. Third, the geometry of the assembled is represented as vertical and horizontal bands or pattern pieces like puzzle, impressing geometry, three-dimensional, etc. Fourth, repeated structure of the weaving pattern is represented as repetitive patterns of woven fabric or printing techniques. Thus, it impresses repeatability, harmony, etc. And lastly, continuous group structure is represented as a connection of collars or hem-lines, as well as a crossing of fabric that impresses continuity, liquidity, etc.

  • The purposes of this study are to comprehend the internal meaning and the external form in style of Greek statue's clothing in the light of linked solution, and to compare the characterizations of style of Greek statue's clothing with those in Greek Art. For these purpose, the theoretical studies about Greek art are preceded as a framework of this research, and then plastic characteristics of Greek statue's clothing and Greek art are analyzed by the documentary studies, For sources, photographs of Greek statue in Archaeological Museum and Louvre museum are used. The result is as follows. It is demonstrated that the characters of internal meaning in style of Greek art and Greek statue's clothing. The internal meaning of style of Greek art and Greek statue's clothing are as follows 1) Beauty of vital is subject that possessed life and movement and embodied dynamics or inherent power. 2) Beauty of moderation is subject that achieves some of its most impressive and practise a similar economy and restraint. 3) Beauty of character is subject that reveals the character of its wearer and has its own charm and distinction The Greeks clarified beauty by looking for mathematical proportions. It is the interrelation of part with one another, and with the whole, together with the additional element of good colour, which constitutes beauty as perceived by the eyes. The beauty in style of Greek statue's clothing consists of a sense of geometrical pattern, oder, symmetry, proportion, and rhythm.

  • Hangeul is growing as cultural icon representing Korea. And Hangeul is scientific and is too systematics for words as the guide of modern design. First it can make the variable and beautiful foams like dot, line and plane. It also has the basic design principles like symmetry and repetition. The purpose of this study is to develop textile designs using the formative characteristics of Hangeul. So in this study it was chosen 'ㄱ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅍ' of Hangeul's consonants and 'ㅑ, ㅕ' of Hangeul's vowels as the subject materials of textile designs development to develop textile designs expressed the geometrical shapes and formative beauty of Hangeul. Those are designed by using a variety of motifs that recast the shapes of Hangeul. So six textile designs for necktie and scarf were developed. Through this study it will be offered to the possibility of products that was based on Hangeul.

  • Many factors should be considered by architects and designers for designing a tall building. Wind load is one of these important factors that govern the design of tall building structures and can become a serious challenge when buildings tend to be built very tall and slender. On the other hand, through the initial stages of a design process, choosing the design geometry greatly affects the wind-induced forces on a tall building. With this respect, geometric shapes with 3-fold rotational symmetry are one of the applied plan shapes in tall buildings. This study, therefore, aims to investigate the aerodynamic characteristics of 8 different geometrical shapes using Computational Fluid Dynamics (CFD) by measuring the drag and lift forces. A case study approach was conducted in which different building shape models have the same total gross area and the same height of 300 meters. The simulation was an incompressible transient flow that ran 1700 timesteps (85 seconds on the real-time scale). The results show a great difference between wind-induced force performance of buildings with different plan shapes. Generally, it is stated that the shapes with the same area, but with smaller perimeters, are better choices for reducing the drag force on buildings. Applying the lift force, the results show that the buildings with plan shapes that have rounded corners act better in crosswind flow while, those with sharp corners induce larger forces in the same direction. This study delivers more analytical understanding of building shapes and their behavior against the wind force through the parametric modelling.

  • Aim of this study is to investigate the feasibility of 2D ion chamber array as a substitute of the water phantom system in a periodic Linac QA. For the feasibility study, a commercial ion chamber matrix was used as a substitute of the water phantom in the measurement for a routine QA beam properties. The device used in this study was the I'm RT MatriXX (Wellhofer Dosimetrie, Germany). The MatriXX consists of a 1,020 vented ion chamber array, arranged in $24{\times}24\;cm^2$ matrix. Each ion chamber has a volume of $0.08\;cm^3$, spacing of 0.762 cm. We investigated dosimetric parameters such as dose symmetry, energy ($TPR_{20,10}$), and absolute dose for comparing with the water phantom data with a Farmer-type ionization chamber (FC65G, Wellhofer Dosimetrie, Germany). For the MatriXX measurements, we used the white polystyrene phantom (${\rho}:\;1.18\;g/cm^3$) and also considered the intrinsic layer (${\rho}:\;1.06\;g/cm^3$, t: 0.36 cm) of MatriXX to be equivalent to water depth. In the preliminary study of geometrical QA using MatriXX, the rotation axis of collimator and half beam junction test were included and compared with film measurements. Regarding the dosimetrical QA, the MatriXX has shown good agreements within ${\pm}1%$ compared to the water phantom measurements. In the geometrical test, the data from MatriXX were comparable with those from the films. In conclusion, the MatriXX is a good substitute for water phantom system and film measurements. In addition, the results indicate that the MatriXX as a cost-effective novel QA tool to reduce time and personnel power.

  • Dioxobis(sub.-salicylaldiminato) molybdenum (VI) complexes, $MoO_2\;(X-sal-N-R)_2,\;(X=H,\;5-CH_3,\;R=C_6H_5,\;p-F-C_6H_4,\;m-Cl-C_6H_4,p-I-C_6H_4\;and\;p-C_2H_5-C_6H_4)$, have been prepared by reactions of dioxobis(sub.-salicylaldehydato) molybdenum (VI), $MoO_2(X-sal)_2$ with primary amines, in which $MoO_2(X-sal)_2$ complexes were obtained by acidification of a mixture solution of ammonium paramolybdate in water and appropriate salicylaldehyde in methanol. All these complexes show two strong Mo=O stretching imodes in the 900-940$cm^{-1}$ and p.m.r. spectra exhibited only one signal for the azomethine group. These results confirmed that the complexes are six-coordinated octahedron with a $cis-MoO_2$ group and the geometrical configurations of the complexes possess a C2 axis of symmetry. From the mass analyses of the complexes, it found that the composition ratios of $MoO_2$ : ligand are 1 : 2. The charge transfer transition corresponding to N-Mo, and O-Mo occured at 29,000$cm^{-1}$ and 32,000$cm^{-1}$ respectively. Where, the complexes were found to be non-ionic materials by conductivity measurements in dimethylformamide.

  • The purpose of this study was to analyze commemoration characteristics of the United States of America, the Commonwealth, and Germany through representative 14 military cemeteries of World war II in Western Europe. Based on the commemoration characteristics such as spacial characteristic, commemorative elements, and graves and headstone, the commemoration culture among U.S., the Commonwealth. and Germany were studied comparatively. The results are as follows. First, taking geometrical form with mainly square type, rarely circle and spiral patterned, most cemeteries were structured spatial central axis with symmetry, those cemeteries were styled neoclassical, but some of the U.S. cemeteries were modernistic, connecting spaces organically with curved line layout. Second, chapel, the wall of missing, the wall of battle map, and sculpture in the U.S military cemeteries, and 'the cross of sacrifice' and 'the stone of remembrance' as classical monument in the Commonwealth war cemeteries were commonly applied standardized commemorative elements, but commemorative monuments in German military cemeteries were restricted except monumental cross. Third, the symbolic cross of christianism was used all cemeteries to console and cherish the soul of soldiers, specially the Latin crosses in the U.S military cemeteries delivered political message as the american martyr for Western Europe and also the power of the U.S., but the cross in German and the Commonwealth war cemeteries were basically cherish and comfort individual spirit. Fourth, showing the power of victory with national patriotism, the U.S. strongly represented christianism and liberal democracy against communism, the Commonwealth showed imperialistic style, and German military cemeteries were quietly appeared as traditional style forwarding reconciliation and peace. This study suggest the war cemeteries have national identity with typical form and symbolic aesthetics. Further study will be required to materialize sublime commemoration in national cemeteries and to form advanced commemorative culture in Korea.
