Louis I. Kahn's spacial composition is characterized by traditional motives and Ecole des Beaux which had influenced him. This influence had showed five forms about Kahn's spacial composition. His constituent factors in geometrical form are classified into the propositional system, the cellular multiplication of a special unit, the Poche Space and others. According to the results of this study obtained from above mentioned subjects, it can be concluded that geometrical factors, which constitute space of plan, are totally expressed as a system of order which unites particular ones into whole one. This characteristic had developed into a completed meaning for passing through the residential architecture in 1950's, and showed in the other artworks there after.

The gamma-ray exposure doses in decontamination operation after a nuclear accident were evaluated with a consideration of various geometrical conditions and specific gamma-ray energies. The calculation domain is organized with three residence types and each form is divided into two kinds of geometrical arrangements. The position-wise air KERMA values were calculated with an assumption of evenly distributed gamma-ray source based on Monte Carlo radiation transport analysis using the MCNP code. The radioactivity is initially set to be unity to be multiplied by the deposition value measured in the actual accident condition. The workforce data set depending on the target object was determined by modifying the Fukushima report. The external exposure doses for decontamination workers were derived from the calculated KERMA values and the workforce analysis. These results can be used to efficiently determine the workforce required by the characteristics of the area and the structure to be decontaminated within the dose limits.

This study aims to make clear visual quality of organic form and structural order that is immanent in nature about a form as formative principles of architectural space design the significanced of this study is to prove the application possibility in to functional form architectural space design. All organic forms in nature has a unique shape and pattern in structure to be self-controled and good in order. Such an order in nature comes from regular construction and ratio principles which has aesthetical order by mathmetics. The specialty of beauty in nature can be revealed not only visual form but also the ratio balance and rhythm of structural principles. As we examine the aesthetic source embodied some object can be developed in to basic principles. Furthermore through this study we can find out that the form construction theory in nature forms share the quality attribute with geometrical form to be shown in architectural space design. Natural forms are ultimate visual expression of power that effects on the architectural space design. The rule of power in nature as nature formal characteristics have a direct influence and can be also applied to architectural construction. Therefore I expect that this study will be linked and continued to another structural view.

The purpose of this study was to analyze the expressional characteristics of the machine aesthetics in the fashion design. First, this study was started from analyzing mechanical beauty represented on the early 20th century art style. Machine aesthetics has influenced on the art and fashion design from modern to now. Futurism was grounded in the complete renewal of human sensibility brought about by the great discoveries of science. Especially, Russia avant-garde was inspired by the Futurism, that is Rayonism, Constructivism, Suprematism. Kasimir Malevich moved on immediately to purely abstract paintings of which the first was a black square on a white canvas. He had begun the art he called 'Suprematism'. Malevich's geometry was funded on the straight line, the supremely elemental form which symbolized man's ascendancy over the chaos of nature. The square was the basic suprematist element and was a repudiation of the world of appearances, and of past art. He repudiated any marriage of convenience between the artist and the engineer. Vladimir Tatlin made some of the most revolutionary works of modern art, these were the first works to be called 'construction'. Constructivists believed that the essential conditions of the machine and the consciousness of man inevitably create an aesthetic which would reflect their time. They eulogized simple shapes. That believed that buildings and objects should be freed from the ornamental excrescences and the accumulated barnacles of past art. Consequently, under the theoretical background, the result is as follows. First, The functional formativeness of machine aesthetics was expressed as a geometrical silhouette, construction line, non-ornamental construction, simple color in the 20th century design. Second, The mechanical formativeness of machine aesthetics was expressed as a construction of new material-iron, aluminium, plastic, glass-, geometrical form of material in he 20th century design. That is, machine beauty has more concerned with the expressional ideology of the art style and the formativeness of fashion design by silhouette, construction line, material, form.

In the 1970's the Interior Design Associations was established and the activity of youth designers who werecalled the "first generation of Korean interior designers" were created. This study is aimed to analyze characteristics and trends of commercial interior design in the 1970's. The design methods include the documentary research and the actual proof research conducted. The frames of analysis were made by the background theories about Korean interior design, and the annual case studies were analyzed and estimated according to the design types. The design types were analyzed by the geometrical simplicity research, the romantic emotional expression, the Korean identity expression, the machine technical asthetic expression and the eclectic style with western classics. In the early 1970's, the abstract, brief, and simple expression were presented most frequently by the geometrical form and the repetition of the pattern. From the mid-1970's the romantic and emotional atmosphere of the youth culture that was popular at that time were expressed as vernacular design by the rough finishing of the natural materials such as plaster, brick, and wood floorings etc. The space such as a Korean food restaurant relates to the Korean traditional culture aims to be different through the expression by the Korean traditional patterns, furniture, and materials. In the late 1970's the metals and glass were used for the expression of the machine aesthetic form but was not popular because of the rare application. The type that revived the past western traditional form was presented by using the arch, dome, and the curved and luxurious moldings.

This study examines the morphological expression type and formative characteristics of women's shoes designs that integrate 3D printing technology. The results of the study are as follows. First, the morphological expression types of contemporary shoes that integrate 3D printing technology express a structural form created by repetition. Second, it expresses a dynamic form, which combines organic curves that create an external volume. Third, it expresses a surrealistic form centered on an object with the creation of a unique shape that utilizes objects easily experienced in local surroundings. Fourth, it expresses a hybrid form on a partial derivation. Each of the other system's components are fused to create another beauty that develops a new value in a colorful variation on the shape of 3D printing shoes. The first formative characteristic of women's shoes designs that integrate 3D printing technology is continuity. This creates an invisible form of a new space through repetitive unidirectional layers with a gradual expansion of a unitary seamless curves. Second, it is an exaggeration. This exaggeration elicits an enormous aesthetic quality by structuring the outward space in the difference of the volume formed based on the maximization of a specific part and the volume of a line's atypical movement. Third, it is a decoration. It displays the beauty of a decoration that evokes a unique artistic inspiration by partial unification or a practical representation of a specific form. This can also be seen as superimposing a 3D printing figure that has an outstanding shape onto part of the fashion shoes. Fourth, it concerns a geometrical characteristic that formulates a new structure with rationality in combining basic shapes such as circles, triangles and squares with lines, hexagons and interconnected geometrical forms to create a multi-dimensional space for shoes in a systematic and unidirectional pattern.

Latticed domes take form a curved surface by arranged members with certain patterns. For this reason, it is possible for the characteristics of vibration to complicate by change of various parameters of dome; grid-pattern, boundary condition and ratio of radius-height etc. Therefore, it is important to clarify the effect by these parameters before generalized dynamic response analysis. So this study deals with free vibration analysis of latticed domes and makes clear an effect of shape coefficient, that is, geometrical characteristics of latticed domes, on the vibration characteristics.

The reactor impedance is calculated for a planar-type cylindrical inductively coupled plasma source by expanding the electromagnetic fields into their Fourier-Bessel series forms including the three-dimensional shape of the antenna. The mode excitation method is utilized to determine the electromagnetic fields based on a Poynting theorem-like relationship. From the obtained electromagnetic fields, a tractable form of the reactor impedance is obtained as a function of various plasma and geometrical parameters and applied to carry out a parametric study.
