  • The purpose of this study is to help understanding of Korean fashion image by studying of design factor and formative characteristic. The methods of this study are the study of academic literatures as well as practical study through the analysis of case studies about actual works. The summary of this study's results is like followings. First, Perspectives seeing formative characteristic on Korean fashion image are Shape with a line, color, material, pattern, accessories. Second, Design factors deciding Korean fashion image are pattern, then in order of shape, color, material, accessories. Third, In results on design factor deciding Korean fashion image, when fashion designers focus on pattern, pattern is focused on without regard for other design factor. But color and material are accompanied by other design factor in expressing Korean fashion image. As fashion design point expressing Korean astetic, use of pattern is minimized other design factor, color and material are used with other design factor, then Korean fashion image will come out more than other time else. If We develop Korean fashion design to concentrate on shape and pattern, Korean fashion culture will be known to world people and beautiful value of Korean fashion will be handed effectively.

  • For micro-machines, very few design methodologies based on optimization hale been developed so far. To overcome the difficulties of design optimization of micro-machines, the search method for multi-dimensional design window (DW)s is proposed. The proposed method is defined as areas of satisfactory design solutions in a design parameter space, using both continuous evolutionary algorithms (CEA) and the modified K-means clustering algorithm . To demonstrate practical performance of the proposed method, it was applied to an optimal shape design of micro electrostatic actuator of optical memory. The shape design problem has 5 design parameters and 5 objective functions, and finally shows 4 specific design shapes and design characters based on the proposed DWs.

  • This treatise deals with the profitable suit image design of middle-aged men by examining visual effects in physical design. The sample of this study is people who lives in Kwangju, the Republic of Korea and 20-50 age's men and women. And it is very variety in each population statistics factors the differences of associate design visual effect which considering the difference of sex and age group, numbers of button, a figure and material pattern. Firstly, look into the associate design visual effect by sex and button number. In men's group, the style with three buttons was the most attractive and that with two buttons was the least attractive. In 50's group, the style with two buttons was the least attractive and those with 1.3 and 4 buttons were a little attractive. Secondly, in the difference of associate design with sex and shape, men's group was considered that standard type was the most attractive shape, women's group was thought that lean and standard types were the most attractive shape. So we can know that the attractive shape is different with sex. In the difference of association design with age and shape, 20's considered that standard type was the most modernistic and fat type was the least modernistic. 30's considered that lean type was the most modernistic and 50's thought that fat type and standard type were the most modernistic. Thirdly, see the sex and material pattern. In familarity, men's group considered that stripe pattern was more familiar than checks and plain patterns. And they considered that striped pattern and plain was more manly than checks. In sex and material pattern, 20's thought that plain was the most attractive, stripe was the next, and checks was not attractive. 40's estimated that plain and stripe were more attractive than checks. 50's judged that stripe was the most attractive material. Thus. the attraction is different with ages and material patterns.

  • The purpose of this study is to analyze formative features of women shoes, to develop distinctive shoes design for coming fashion trend. the methods of this study are documentary research and case study. In the theoretical study, this study has catched the origin of shoes and the changes of shoes design of each era. for the study of formative features of women shoes in 1990's, 215 kinds of pictures have been selected from in professional shoes magazines. The results of analysis are as follow. Woman shoes categorized the design factors into shape, material, decoration. Reformational shape that reconstructs old shape of shoes by comtemporary aesthetic, shape in that dual images were mixed, re-created shape that was constructed through the reconstruction of structures and shapes of shoes. Material image was strengthened by varying patterns of unburned calf, leopard and zebra. Avant-garde was appeared by using naturalistic material to represent natural beauty or using merry, daring material. Post-modern tendency was appeared like using brassiere strap instead of back strap or using round string in elegant shoes.

  • In this study, a shape design and an analysis considering structural stability were investigated to develop an icosahedron-based hemispherical modular dome. To design this modular dome, a program that can perform icosahedron shape modeling, modularization of joint connection members, and the analysis of structural stability was developed. Furthermore, based on the adopted numerical model, the eigen buckling mode, unstable behavior characteristics according to load vector, and the critical buckling load of the modular dome under uniformly distributed load and concentrated load were analyzed, and the resistance capacities of the structure according to different load vectors were compared. The analysis results for the modular dome suggest that the developed program can perform joint modeling for shape design as well as modular member design, and adequately expressed the nonlinear behaviors of structured according to load conditions. The critical buckling load results also correctly reflected the characteristics of the load conditions. The uniformly distributed load was more advantageous to the structural stability than concentrated load.

  • In this paper, method for mapping a three-dimensional shape into the two-dimensional plane will be introduced. This method is referred to geometric modelling and means a transformation between the flat sheet and final surface. The initial blank shape represents the original configuration of the final shape formed into three dimensional surface. The initial constant constant area mapping hypothesis was used in this paper. This technique will be applied to the basic data for an interactive computer design capable of dealing with typical stamping process, including deep parts and complex shapes.

  • The structural shape optimization is a useful tool for engineers to determine the shape of a structure. During the optimization process, relocations of nodes happen successively. However, excessive movement of nodes often results in the mesh distortion and eventually deteriorates the accuracy of the optimum solution. To overcome this problem, an efficient method for the shape optimization has been developed. The method starts from the design domain which is large enough to hold the possible shape of the structure. The design domain has pre-defined uniform fine meshes. At every cycle, the method judges whether all the elements are inside of the structure or not. Elements inside of the structure are assigned with real material properties, however elements outside of the structure are assigned with nearly zero values. The performance of the method is evaluated through various examples.

  • The Performance of a PEMFC stack is strongly dependent on the uniform reactants distribution on MEA. The uniform distribution can be achieved by flow-field pattern and manifold design optimized to satisfy operating conditions. This paper investigates uniform reactants distribution in channels by changing manifold shape and inlet mass flow rate. Typical U and Z shape and modified U and Z shape manifolds with buffer zone were designed. To check the uniform reactants distribution, standard deviation of mass flow rate was compared. The numerical results show that the inlet mass flow rate, inlet shape, and manifolds shape are critical factor for uniform distribution.
