This study investigates transformable designs in contemporary fashion. In contemporary society, designs are accompanied by various changes such as transformation of shapes or variation of material beyond the certain form of dress. As a result of having interest in transformable designs with the various attempts on the overall design, transformable design is being suggested as an attempt as the new manner, radical concept, or alternative of multi-purpose lifestyle. With the constant research and collection presentation by the designers of empirical disposition, transformable dress has been evolving gradually. The feature of transformable design appeared in dress is considered as 'variability' which changes in the flow of time. Furthermore, the morphological variability and variability of material have been examined as visual stimuli and conversion of material. By analyzing and assorting diverse transformable dresses comprehensively, it could be divided into technique-oriented transformable design and transformable design with a wearer's intervention. The technique-oriented transformable design is subdivided into the conversion of material and the conversion of form; the transformable design with a wearer's intervention into the conversion of functional frame and the conversion of aesthetic feature.

In the construction of dam, the key factor which decides the type of dam is security of materials resource. Because of the large scale earth work, the ability to supply the materials is essential part about economical efficiency. The research is the case study about controlling the plan to secure the material resources in the design of Buhang multipurpose dam. In case of Buhang multipurpose dam, at that time of basic design, it was planned to use a rock fill material. From the detail investigation about the river bed accumulative layer widely spread on the submerged district on the basic design, the research is accomplished to replace rock material with gravel material. After the investigation of whole reserves of gravel material, estimation of conformity as dam construction material from analysis of grain size distribution, the case study of oversea construction, and the material property comparison between rock fill material and gravel fill material, it is verified th possibility of using the gravel fill. Thereafter, the analysis of dam stability using a gravel fill material is accomplished. Finally, A gravel fill material can be used as the main construction material of CFRD, therefore the efficiency of resource recycling in the submerged area is maximized, and the established plan is more advantageous to stability, constructibility, environmentibility than the case of using a rock fill.

Carbon material was used for the new module-type bicycle accessory focusing on the user convenience through service design methodology. In the case of using the existing carbon material, the impact could not be endured while riding the bicycle and there was the case of breaking. To resolve this kind of problem, the new type of material (S Foam Core material) was applied. The intensity, twist intensity, shock absorbing power, and vibration were measured for the existing carbon material and the S Foam Core material. As a result, the S Foam Core material showed more outstanding results than the existing carbon material. This study produced prototype with the S Foam Core material to verify the performance through tests and report the result.

At the initial design stage, the generation process of the production material information of a building block and the simulation process of the block erection, which are required to perform the production planning and scheduling, have been manually performed by using 2D drawings, data of parent ships, and design experiences. To make these processes automatic, the accurate generation method of the production material information and the convenient simulation method of the block erection using the 3D CAD model, which was generated from the initial hull structural design system early developed by us, were proposed in this study. For this, a 3D CAD model for a whole hull structure was generated first, and the block division method for dividing the 3D CAD model into several building blocks was proposed. The generation method of the production material information for calculating the weight, center of gravity, painting area, joint length, etc. of a building block was proposed as well. Moreover, the simulation method of the block erection was proposed. Finally, to evaluate the efficiency of the proposed methods for the generation of the production material information and the simulation of the block erection, these methods were applied to corresponding processes of a deadweight 300,000 ton VLCC (Very Large Crude oil Carrier). As a result, it was shown that the production material information of a building block can be accurately generated and the block erection can be conveniently simulated in the initial design stage.

This paper brings up fallacy of material factors specified for the design of concrete members in the current Korean limit state design code for highway bridges, and proposes new material factors based on a robust optimization scheme to overcome the fallacy. It is shown that the current load factors in the code and the proposed material factors lead to a much higher reliability index than the target index. The load factors are adjusted to yield the target reliability index using the inverse reliability analysis. A reliability-based approach following the basic concept of Eurocode is formulated to determine material factors as well as load factors. The load-material factors obtained by the proposed reliability-based approach yield a lower reliability level than the target index. Drawbacks of the basic concept of Eurocode are discussed. It is pointed out that differences in the uncertainties between materials and members may cause the lower reliability index of concrete member than the target.

Since 1990s the concern on essence and inside has transferred onto the surface and its style. The longing for plastic surgery and skin beauty might prove this fervent tendency. Furthermore the development of digital media and technology as well as high-tech material enabled this hope to be real in the realm of design. All these progresses and transitions toward the surface introduced more creative and novel phenomena of furniture design arena around its surface. The rising of surface has evolved through architecture, interior design and furniture. The surface of furniture can be easily transposed into the human skin. And it acquires the aspects of skin's metaphoric and symbolic meaning. The characteristics of skin effect in furniture design can be summarized as material aspects, relational aspects, and formal aspects. Material aspects shows skin's elasticity and smooth plane. Relational aspects express the reactive functions of skin. Formal aspects represent organic power through surface.

The purpose of this study is providing a systematic method of exterior, interior finish materials and color scheme for elementary school and the actual color plans of elementary schools in Busan was analyzed to support the study. As a powerful design tool, a finish materials and a color are very effective to alter the perception of a building and a view. Most of the school, a shape and a material of elevations are monotonous and uniform and it makes students are hard to attach to their schools. As a place for learning and school life, the inner space of elementary classroom needs to be considered very important. The new basic guideline for developing and planning of architectural design could be achieved by researching a current plan and a finish material in elementary school. As a result, this study will benefit in planning both the exterior and interior environments of color.
