Presented in this paper is the development of an product cost estimation system at the product design stage. The efficient cost estimation function at the design stage is essential for the cost reduction activities through the entire product life cycle. For this purpose, it is necessary to establish a systematic working procedure, and to develop information system for managing a great deal of production and product-related data required for the cost estimation. The developed system has the capability of estimating a cost of assembly type products as well as unit-item type products. As proposed system is based on the variant approach, it can be used easily at an early design stage without the need for detail design information. Also, this system is integrated with legacy PDM (Product Data Management) and ERP (Enterprise Resource Planning) system for fast. accurate and easy product cost estimation. The estimated cost includes material cost, overhead cost as well as labor cost.

This paper presents a systematic approach for design of timely and proper layouts of a manufacturing system facilitating reconfigurability, referred to as a reconfigurable manufacturing system. A proper methodology for design of a system layout is required for reconfiguration planning - adding or removing machines for supplying the exact capacity needed to fulfill market demands, as well as minimizing the cost of adding new machines. In this paper, theory of constraints is used to make reconfiguration manufacturing systems more cost-effective and efficiency. The proposed approach is validated by using a real industrial case. This paper suggests that the proposed study should be performed concurrently with the design of a new manufacturing system.

The heat and flow characteristics in a parallel-flow heat exchanger were examined numerically to obtain its optimal design variables. A desirability function approach was introduced to optimize its performance with respect to the design parameters over the design domain. By varying the importance of heat transfer and pressure drop which are out put variables, the optimal values of the design parameters are examined. As a result, the us-age of the desirability function is very effective for the optimization of the design variables in a heat exchanger since the changes of optimal values are physically appropriate by varying the importance of each output variable.

For taller buildings with unconventional architecture, refined structural systems or in geographical areas with high wind conditions, performance-based design can be seen as an enhanced design process and is either a supplement to, or alternative to a prescriptive code-based design. The ultimate goal of Performance-Based Wind Design (PBWD) is to result in a building that better addresses key goals of performance over the buildings full life cycle. Major innovations around the use of a PBWD approach include nonlinear dynamic analysis for wind design, limited inelasticity in the main wind force resisting system elements, and system-based performance criteria. This paper discusses potential considerations and benefits made when using a performance-based approach, in addition to the general practicality of use, for the structural design on a few key tall buildings.

In recent years, the Guochao style of virtual idols has proliferated, and the virtual idol market in China has witnessed gradual growth. As Guochao combines traditional Chinese culture with modern aesthetics, it shapes a distinctive visual identity for Chinese virtual idols. We address the current research gap by exploring the characteristics of Guochao style in virtual idol design through literature analysis, semiotics, and comparative studies. We examine how Guochao virtual idols represent the convergence of Chinese culture and modern technology, reflecting cultural characteristics of the era. Through our analysis of virtual idol design, we identify key design features of Guochao virtual idols, bridging a theoretical void in this area. We propose recommendations to foster a more dynamic and culturally enriched virtual idol industry in China. Our research provides new insights into integrating Guochao elements into virtual idol design as an approach to differentiate amid competition while promoting traditional Chinese culture through digital media. We demonstrate how this design approach enhances the uniqueness and cultural value of Chinese virtual idols, contributing to the field's theoretical foundation and practical applications.

In this paper, a Performance Based Design (PBD) approach is validated for multi-storey concentrically braced frame (CBF) systems. Direct Displacement Based Design (DDBD) procedure is used and validated by designing 4- and 12-storey CBF buildings. Nonlinear time history analysis (NLTHA) is used to check the performance of the design methodology by employing different accelerograms having displacement spectra matching the design displacement spectrum. Displacements and drifts obtained from NLTHA are found to fall within the design displacement limits used in the DDBD procedure. In NLTHA, both tension and compression members are found to be resisting the base shear, $F_b$, not only the tension members as assumed in the design methodology and suggested by Eurocode 8. This is the reason that the total $F_b$ in NLTHA is found to be greater than the design shear forces. Furthermore, it is found that the average of the maximum ductility values recorded from the time history analyses for the 4-and 12-storey buildings are close to the design ductility obtained from the DDBD methodology and ductility expressions established by several researchers. Moreover, the DDBD is compared to the Forced Based Design (FBD) methodology for CBFs. The comparison is carried out by designing 4 and 12-storey CBF buildings using both DDBD and FBD methodologies. The performance for both methodologies is verified using NLTHA. It is found that the $F_b$ from FBD is larger than $F_b$ obtained from DDBD. This leads to the use of larger sections for the structure designed by FBD to resist the lateral forces.

Ship design engineering refers to the development and design of shipbuilding architectures in a drawing which reflects all relevant manufacturing processes. This paper provides analysis methods for model-information interfaces between hull structure design and outfitting design, and a technical application for manufacturing phases reflecting the pipe support pad and angle item automatically. The existing information procedure of pipe support pad and angle system processes information using drawing without model specification. Outfitting design team directly distributes drawings to the shop floor then manual-based marking and installation work are conducted refer to the distributed drawings. As a result, this process has become time consuming and causes problems in the productivity and quality improvement due to the rework caused by omitted or incorrect marking. The pipe support pad and angle marking is a method that automatically updates model information to hull structure design using sets of data that analyse the generated model in outfitting design processes. Therefore, this approach provides an efficient solution through design references without manual activities such as a reflection of hull structure design, cutting process, numerical control work, and dimension measurement and marking. The conversion of a method from the existing procedure based on manual marking to the reflective and automatic approach would have enabled to proceed installation work without manual activities for the measurement. Therefore, this research study proposes an efficient approach using pre-data analysis of model information interfaces between design and manufacturing phases to improve productivity during construction for shipbuilding.

Creative spatial production in Environmental design relies, in large part, on the artistic talent of the designer(s) that is applied to the design solutions or schematic plans. This study proposes the importance and necessity of the use of 'Plastic Arts" or the technique of artistic manipulation and definition of space in Environmental Design studio programs. This fundamental design approach is currently lacking in Korean design studio programs. Moreover, the current trend of interdisciplinary design (that is, between landscape architecture, architecture, urban and environmental planning) emphasizes the importance of such techniques. "plastic Arts" techniques can serve as a basic code of communication between design disciplines and can in itself be a common approach. The method of this study is based on the empirical datas, that is, the educational performances which are executed in Landscape studio programs of some Korean Universities. The results are summarized as follows; 1. The program, "Plastic Arts" Should be included in the basic organization of Landscape design studio programs. 2. Unlike France where "Plastic Arts" program is implemented through out Landscape Architecture programs in Korea, "Plastic Arts" should be intensified and continued for longer period of time for students in the initial years. 3. In creation of "Plastic Arts" programs for Korean Landscape Design studios, the traditional and contemporary values of aesthetic of the Nature should be taken in consideration. 4. In order to confirm the necessity of "Plastic arts" program in the organization of landscape curriculum, more studies should be done, with empirical datas.pe curriculum, more studies should be done, with empirical datas.
