The purpose of the present study is to find design factors that have an effect on man's foot, and to develop an optimal last for man's functional shoe design based on these factors. Analyzing 4000 men's foot data, three men were selected for fitting test with the last and shoes manufactured in the present work. Based on the results of the fitting test, the modifications of last for the optimal design have been made using CAD/CAM technologies.

In this paper, we present mathematical models for the ring covering problems arising in the design of multi-ring WDM networks. Also, we present efficient algorithms to solve the suggested models. By the computational experiment, our model can solve the medium-sized networks efficiently and shows better performance than the existing heuristic method. Although we propose an efficient method for the column generation procedure, branching rule that does not destroy the column generation structure is unsolved. Further research is required to develop an effective branching rule.

The purpose of this study is in planning clothing and bag design and VMD. For this purpose, the pret-a-porter fashion collection is divided into the following sectors: brands, years, and seasons, focusing on the design elements. The results of this study are as follows: 1. It is these three ways that determine the relevance of clothing and bag design planning. first, we have analyzed design properties analogously with one design element, like Louis Vuitton. Second, we considered design properties analogously with two design elements, like Chanel, Gucci, Prada. Third, we examined design properties analogously with three design elements, like Christian dior, Fendi, Etro. 2. The comparison of clothing and bag design properties year by year shows that they were mainly designed with an analogous aspect with pattern and decoration. 3. Clothing does well to match a bag between analogous design properties of design elements to express similarity coordination and between contrast design properties of design elements to express plus one coordination or crossover coordination. 4. The aspect of coordination of clothing and bags year by year is different period. This is because of clothing and bag design's change according fashion trend. 5. S/S coordination of clothing and bags is effective to present plus one coordination or crossover coordination. And F/W coordination of clothing and bags is effective to present similarity in coordination.

In recent years, design of an optimal blank shape is very important for sheet metal forming process in the automobile industry because the raw material cost rate is significant part in the automobile industry. With the design of an optimal blank shape, the engineer can protect a blank from an excessive holding force to improve the quality and reduce the ratio of material scrap. Therefore design of an optimal blank shape is inevitable in sheet metal forming process. However, if it causes a complicated shape of blank, it may be difficult to do the blank layout optimally. In this study, we developed software of optimal blank layout connected with the software of optimal blank shape design which was created in the past by the present authors. And by using these softwares, we would like to present the method in order to get optimal utilization ratio easily and precisely within short time for the sequence of works from design to blank layout.

An iterative numerical computational algorithm is presented to design a plate or shell element subjected to membrance and flexural forces. Based on equilibrium consideration, equation for capacity of top and bottom reinforcements in two orthogonal directions have been derived. The amount of reinforcement is determined locally, I. e., for each integration point, from the equilibrium between applied and internal forces. Three cases of design are performed for slab element (used by Marti(1987)) and shell element (used by Kirscher and Collins(1986), by Polak and Vecchio(1993)) to verify the adequacy of the present design method for reinforced concrete shells. Based on nonlinear analyses performed, the analytically calculated ultimate load exceeded the design ultimate load. This shows the adequacy of the design method present in this study at least for slab and shell element case studied. To generalize the conclusion more design-analyses should be performed with different shell configurations.

Aerodynamic design of the vane type multi-function probe was tried by using CFD and wind tunnel test for the MALE UAV and small business jets. The present multi-function probe can measure total pressure, static pressure and angle of attack by using rotating vane. Therefore, major performances are determined by aerodynamic characteristics of vane. In order to design the sensor compatible to the requirement, aerodynamic characteristics of sensors were investigated by using CFD and dynamic response analysis was also performed for transient performance. The final aerodynamic performance was measured by the wind tunnel test at Aerosonic and the results were compared with the present design. The results showed that the aerodynamic design using the CFD can be successfully used for the design of vane type multi-function air data sensor.

The present study aims at establishing the design procedure of regenerative pumps. It is based on the new momentum exchange theory proposed in Yoo, Park and Chung. Salient feature of the present design procedure is that it does not require input of any kinds of empirical design data. Using the design procedure, a prototype regenerative pump has been designed and manufactured to confirm its validity. Comparison between the predicted performance and the experimental measurement reveals that the prototype pump has its maximum efficiency at the design flow rate and that the proposed performance analysis method satisfactorily predicts the machine performance.

Big 3 Korean department stores - Lotte, Hyundai, and Shinsegae have pursued a differentiation strategy in order to survive the era of big-bang. This study has proposed to present a frame work with which we can recognize the character of design, which is pertinent to a differentiation strategy. The results of study are as follow ; 1) Lotte department store reveals the 3 strategies - location, composition and specialization strategy and the character of design has traditional, high class and neutral disposition. 2) Hyundai department store reveals high class strategy and the character of design has high class and modern disposition. 3) Shinsegae department store reveals high class and specialization strategies and the character of design has high class, tradition and modem disposition.

The past and present time are consistent thinking process system which composed of single concept not separated concept. It's common concept for interior designer to how to realize the thinking process system in actual present day. So this paper was focused on purpose of establishing for procedural process theory by approaching typological process system in interior design process. Interior design being composed of typological thinking process system has been headed as a critical issue to how to transplant well between the design and typological objects. Also we have to be needed to know for the process of visual expression and verbal ability to be able to extract the designer's elements from it. Through the process of visual expression and verbal ability to be able to extract the designer's elements from it. Through the process of visual transformation and analysis we have to extract concepts with united design objects. From these process it should be followed adequate adjudgment on the extracted fragments' assembly and dissociation methods through physical limitation of elements functionality and feasibility's measurements. Therefore from the morphological designed results reflected to typological concepts finished material detail and texture we should be able to take the integrated thinking process system. Lastly interior designer should be able to check whether it was best choice from the consistent design feedback process to ask whether it contains the conceptual design process and new typological objects without non-conformity between past and present days in interior space. Now we should be asked for development of practical design process to be able to realize above assumptions called "Development and Suceeding of Cultural Value System'. Additionally, we have to continue to develop for our true meaning of interior design process, not repetition of past's imitation.tion.
