The spiral form, which comes from the organic form of natural phenomenon such as growth of creatures, has been used as a factor of formative shape in various fields of art until now. In conjunction herewith, this study intends to discover and express the life force and the formative beauty of natural substances with the organic spiral forms into clothing design, using various creating methods and materials such as Korean traditional paper. The natural substances with the spiral structure, such as seashells, land snails, passion flower, curled flower, growing chart of plants, Impatiens textori was used as subjects of the designs. The seven pieces of work were completed with attempts to develop aesthetic forms through the presentation techniques and methods via restructuring process of simplification, partial transformation and consolidation. Through such process the conclusion of this study is as follows: First, the nature, with unlimited possibilities, could be subject of human formative activities, leading to the creative world of formative art for designers. Second, adaptation of the spiral organic forms of nature into the contemporary clothing designs proved the motif as a source of inspiration of diverse subject, in recognition with its innate formative beauty as well as external shape. Third, design expressions via restructuring process of simplification, partial transformation and consolidation with designer's subjective point of view were adequate for the creations of contemporary fashion designs. Fourth, the Korean traditional paper, as a fine material for various shape according to the handling method, could be used appropriately in the contemporary clothing designs, expressing our aesthetic senses. Fifth and finally, expansion of the realm of formative expression of clothing through the development of possibilities of expression in contemporary clothing would enhance the creative possibilities of clothing design as formative art. In conclusion, the expression of clothing design as formative art was developed on the emphasis of re-creation of natural objects of the organic spiral form. For the future study, the applications of spiral form into everyday clothing designs, consolidating artistic senses and practical senses, are expected as opportunity of proposing developmental possibilities of the contemporary clothing designs.

The purpose of study is to relieve the users' anxiety caused by the simplification of the easy money transfer service. With the development of technology, financial services are being simplified, but on the contrary, the chasm occurs. The study was conducted in two rounds. First, based on UTAUT, the perception of the service and the willingness to accept the technology were investigated through a questionnaire. Second, after presenting the tracking function of the remittance situation derived through the heuristic method, in-depth interviews were conducted on reliability and intention to continue using it. As the result, it was found that the clear feedback had a positive effect on relieving users' anxiety. It is expected that studies approaching the chasm from the point of view of design will be actively conducted.

Fashion have been expressed by a face through various a period, social change, and various culture changing. Human expresses as "Transformation" by applying these needs of changing to the fashion. A origin tribe expressed its own self by using direct body transformation and extreme decorations in the past. However, human express creative and esthetic desire based on shape, material, and transformation method in the present time characteristics of the body. Exceptional transformation breaking a existing fixed idea appeared frequently due to dissolution through transformation which is positive expression method in the fashion from 20th century. As a results, followings are obtained in this study. First, human body transforms by using a tool or intermediation in investigation of aesthetic meaning for human body. The object, Transformation, is stably transformed by disintegration, distortion, exaggeration and simplification reduction, as design's sensitivity. Second, transformation from relation of clothing composition is expressed by extension, reduction, simplification, and dissolution. In transformation from original tribe's sensitivity, past decorative desire lead to transformation of human body. To give variable change from past to present fashion, external formative will is introduced. Then, extreme expression is made by direct transformation of clothing type. It seems to be accomplished that human body's expression method is continuously changed into extension, exaggeration, reduction, and dissolution from transformation method as described before. Transformation of modem fashion is expression method by creative supervision. Extreme transformation substituted body's each part is based on immanent play and representative satisfaction. Through these transformation, it is judged that variety of creative type is achieved.

A various methodologies like eco product design, recycling, remanufacturing have been proposed for the increase of resource recirculation and energy saving worldwide. Uni-materialization in this paper, one of measures is presented. Uni-materialization is defined as the unification or simplification of material that is easy resource recycling and reduce waste generation at source during product design, manufacturing, delivery, use and disposal. This study developed calculates the qualitative and quantitative of assessment index for evaluating target products applicable uni-materialization. There are 9 assessment articles considered economic performance, technological property and environmental property and a study on target product applied assessment indexes. As a result it is possible for 3 target products to apply uni-materialization product except for a window blind, and the concrete concept of uni-materialization for improving objectivity of assessment index and the consideration of industrial distinct character are needed.

Many algorithms to find a minimum cost design of water distribution network (WDN) have been developed during the last decades. Most of them have tried to optimize cost only while satisfying other constraining conditions. For this, a certain degree of simplification is required in their calculation process which inevitably limits the real application of the algorithms, especially, to large networks. In this paper, an optimum design method using the Genetic Algorithms (GA) is developed which is designed to increase the applicability, especially for the real world large WDN. The increased to applicability is due to the inherent characteristics of GA consisting of selection, reproduction, crossover and mutation. Just for illustration, the GA method is applied to find an optimal solution of the New York City water supply tunnel. For the calculation, the parameter of population size and generation number is fixed to 100 and the probability of crossover is 0.7, the probability of mutation is 0.01. The yielded optimal design is found to be superior to the least cost design obtained from the Linear Program method by $4.276 million.

Most structure engineers give the casting components over-estimated factor of safety without any reasonable foundation due to the worries about the unavoidable defects such as shrinkages and porosity in castings; the engineers have little knowledge on the relation between the defect and structural behavior. And the workers in casting field also do not know how to control the defects by manufacturing; they do not know to where the defects move or until how size they reduce the defects. In this study, shrinkage defect was scanned by industrial computerized tomography instrument (CT), and subsequently was modeled to a spheroid primitive for structural analysis. Using these simplified models of shrinkage, we observed the effects of the defect on the results of the structural analysis. A commercial structural analysis code was used to do the analysis works. Considering the conclusions, it is possible to manage the shrinkages effectively in casting process and to design the products with more reliable

Traditional methods for monitoring targets rely heavily on probabilistic data association (PDA) or Kalman filtering. However, achieving optimal performance in a densely congested tracking environment proves challenging due to factors such as the complexities of measurement, mathematical simplification, and combined target detection for the tracking association problem. This article analyzes a target tracking problem through the lens of fuzzy logic theory, identifies the fuzzy rules that a fuzzy tracker employs, and designs the tracker utilizing fuzzy rules and Kalman filtering.

The high speed of RSFQ circuits is based on the self-resetting in the overdamped Josephson junctions. The SIS technology using Nb/A1$_2$O$_3$/Nb trilayer has been successfully adopted as a standard technology. However the newly suggested SINIS technology attracts interest because the junction itself is overdamped without any external shunt, and provides possibility of simplification of RSFQ circuit design and fabrication. In this paper we demonstrate RSFQ circuit fabrication process using SINIS technology.

Three recently introduced tenchniques in the area of nuclear analysis are discussed : the structure-factor method of evaluating group material properties, the vector-synthesis method of generating three-dimensional multigroup flux distributions, and an indirect method of defining optimal restricted partitions of neutron phase-space. Each new method is compared with other commonly employed techniques and is shown to be a simplification which leads to a reductions in computational effort while retaining acceptable accuracy.
