This paper explores idea of the integration of text and image information in interior design. In this paper, we designed a structure of text and image information. Text information includes the information about materials and projects, and image information includes images of interior design. Material information consists of such as name and price of materials. Image information involves images of interior design that have been scanned and categorized into 15 groups according to the building regulation. Project information consists of construction brief and materials relevant to the image of interior design. The interior design information that is based on cases offers various information to designer and customers. In addition, the connection between text information and image information improves the quality of interior design by decreasing the trial and error in interior design processes. Finally, we discuss the method that integrates text and image information of interior design.

The coarse grained materials are used in various construction field such as express way back fill, Dam etc. Especially, for dam construction, a huge mount of rock fill materials are needed, so around domestic stony mountains are generally developed to produce materials. Not an accurate theory, but design criteria is based on empirical factors that were constructed in advance for design of dam especially Concrete Face Rockfill Dam(CFRD). Considering the post facts, the modified design criteria are essential in the future with more theoretical and experimental ways. In this study, large scale direct shear tests are performed with various relative density conditions on coarse grained material of Yecheon area to compare test results and general CFRD design factors.

In optimum design of packaging container for bulk materials, minimum board area, compression performance and distribution efficiency must be considered. In this study, mathematical models for minimum board area (RMA), compression strength (CS) and maximum compression strength per unit board area (MCSA) of container as algorithm for optimum design of packaging conatiner for bulk materials were developed as follows : RMA=f(V,D), ${\alpha}_{RMA}=f(V,D)$, MCSA=f(V,D), and ${\alpha}_{MCSA}=f(V,D)$. In order to develop these models, compression test according to various dimensions of container and response surface analysis for minimum board area, compression strength, and maximum compression strength per unit board area of container were carried out. In developed models, volume and depth of container were principal independent variables. Through the verified results for these models, optimum design of packaging container on the design conditions and limit conditions was possible. These models might be used in developing optimum design software of packaging container for bulk materials.

Acceleration of the fashion cycle has caused problems of environmental pollution because consumers made a lot of waste of clothes. To solve them, upcycle design has been uprised. This study researched the present condition through recent cases of upcycle design. The standard of collected cases is focused on used products which was already run out once and then has been recreated by being recreated with new design. Through this study, there is a purpose to provide solution of environmental pollutions and a right direction of upcycle fashion design. Collected cases are classified into five production methods. First method is Melting and Compressing, which it melts or compresses materials. Second method is Gathering and Combining, which it gathers or combines each different materials. Third method is Cutting and Dividing, which it cuts or divides products materials. Fourth method is Mixing and Changing, which it mixes materials, adds design elements, and changes of purpose. Final things are classified with multiplicatively used factors which are already divided.

Temporary scaffold systems in the construction site play an important role for ensuring the safety of the workers and for constructing the stable structures. To assemble the scaffold, the pipe scaffolding system, the wedge binding scaffolding system and the particular materials have been utilized. To design the material arrangement of a scaffold, firstly the configuration was determined considering the construction geometry. Then, the strength of the scaffold was confirmed and the quantity of the material was accounted. In this paper, the design method of the temporary scaffold was proposed for intending the semi-automatic procedure. In the proposed design method, the geometric design and the safety requirement were specified by the safety standard and the design flow was followed by the designer's knowledge. The size and the quantities of the materials were calculated by referring to the relation between the scaffold and the constructing structure. In the calculating procedure, three dimensional positions of each scaffold materials were calculated and recorded simultaneously. Then, three dimensional scaffold structural was drawn semi-automatically on the CAD software by using the obtained material sizes, positions and directions. The proposed design method provides us the precise quantities of scaffold materials and enables us to reduce the design effort and the cost estimation processes. In addition, the obtained results can be applied to BIM software after converting to IFC format.

Sound packages and damping materials have been widely applied on the floor to decrease the interior noise of a vehicle. Based on the previous researches on the low-noise vehicles, weight optimization through minimization of damping material usage is required while decreasing mid and high frequency range noise by application of sound packages. This paper describes the analysis process of robust design of vehicle body structure before applying damping materials and focuses on the analysis and test process of the location optimization at the stage of damping material application. A vibration experiment for the analysis of floor panel velocity with respect to the excitation of suspension attachment parts at the underfloor of a vehicle is performed. And through the improvement correlation between FEA and TEST, a design guide to optimize damping materials application in the early design stage is proposed. A research on vibration damping steel sheets and liquid acoustic spray on deadener(LASD) is performed to minimize manufacturing time and to minimize the space for pre-existing asphalt damping materials. As results of this study, panel stiffness is achieved through curved surface panel and bead optimization. And test baseline of optimum design is suggested through damping material optimization. And finally, through re-establishing the analysis process for vibration reduction of vehicle floors and lightweight design of damping materials, it is possible to design damping materials efficiently in the preceding stage of design.

The purpose of the present study was to improve the artistic qualities in the future fashion design by investigating how the art to wear was applied to the inspiration in the modern fashion design in the late 1990s. For this purpose the present paper examined characteristics in art to wear and their impact on modern fashion design in the late 1990s. Distinguished from the traditional costume, art to wear disregarded a fixed concept on design elements such as the socio-cultural images, materials, and forms. The artists in art to wear freely expressed their "selves" and their individuality to their works in a variety of ways. In fashion design in the late 1990s the creative characteristics of art to wear were reflected in four ways: (1) eco-look, (2) humor, (3) deformation, (4) materials. The present study suggests that the creativity of the art to wear can establish the potentials and possibility in modern fashion design, and art to wear can be a crucial mediator in opening art into the real world.
