The purpose of this study is to develope instructional strategies and assessment model for distance learning in interior design education in Korea. Literature from various sources were examined to provide guidelines for instructional and technical strategies, communication system, and administrative process. Strategies and assessment model for transition to distance learning from goal setting to program evaluation were introduced. The results of this study indicated that distance learning in interior design education is optimized when applied in studio critique, portfolio production, and professional practice and with other traditional programs depending on the characteristics of the instructional materials. It is suggested for further studies that various distance learning programs based on instructional theories to be conducted and evaluated in different areas of interior design education for their maximum application as instructional tool.

This paper considers robust design strategies for off-line quality control, with the use of experimental design and response surface methodology, in situations where all products have multiple quality characteristics. These strategies can be developed using the desirability concept of desirability functions to determine the settings of the design factors, not only to get the average performances on target but also to minimize variability around the target values.

The Purpose of this study is to analyze the green design strategies in residential building, based on case study of Solar Decathlon in USA. This study could provide the basic reference data and theocratical foundation for finding new green design strategies and applicability of green design for korea. The Solar Decathlon is an green design competition that challenges collegiate teams to design, build, and operate the green residential building with optimal energy production and maximum efficiency. As a result of the analysis of this study, the green design strategy is identified and analyzed design issues related in energy, materials, and indoor/outdoor environment. Also, it is useful to find best green design strategy with more economical and environmental benefits presented by renewable energy and design solutions. This study is based on selected 18 green housings of Solar Decathlon from 2002 to 2013. This result is helpful to understand the green design strategies for green residential building's design of modern residential building, and expect future green residential building design approach.

The paper describes the use of genetic algorithms (GA's) to the minimum weight design of stiffened composite panels for buckling constraints. The proposed design problem is characterized by mixture of continuous and discrete design variables corresponding to panel elements and stacking sequence of laminates, respectively. Design space is multimodal and non-convex, thereby introducing the need for global search strategies. Advanced strategies in GA's such as directed crossover, multistage search and separated crossover are adopted to improve search ability and to save computational resource requirements. The paper explores the effectiveness of genetic algorithms and their advanced strategies in designing stiffened composite panels under various uniaxial compressive load conditions and the linrlit on stacking sequence of laminates.

This paper introduces a new optimal design method using a bacterial survival strategies for a ectromagnet of Maglev transportation vehicle. Usually, an electromagnetic suspension which has more advantages than electro dynamic suspension is used in Maglev systems. However, the structural constraints must be considered in the optimal design of an electromagnet for electromagnetic suspend system. In this paper, the optimal design method of a electromagnet based on a bacterial survival strategies optimization algorithm to design the electromagnet satisfying the structural constraints. The effectiveness of the proposed method was verified by Matlab simulations and the simulation results show that the proposed method is more efficient than conventional methods.

Purpose - This paper addresses the role of designers in design-oriented firms and how they should work together with other organization members. The aim of this paper is to investigate how designers generate ideas and cooperate with others as well as how their participation in decision-making reflects on corporate design strategies. Research design, data, and methodology - An in-depth exploratory study examined how designers actually perform their roles in enterprises; in addition, information, knowledge, communication among designers, and sources of creativity were examined. Hanssem and Ikea grew as design-intensive businesses in a declining industry. Data were obtained from interviews with the design staff of each company as well as secondary sources. Results - Designers were found to use their designs to communicate with customers as well as with communities outside of the enterprise; they also participated in overall decision-making in relation to important design strategies. Conclusions - This study emphasized the increasing importance of the innovative and creative role of designers; thus, it might substantially help companies to develop their own design capabilities and deploy design strategies.

This paper presents the optimization technique for design of a CMAC network by using an evolution strategies(ES). The proposed technique is designed to find the optimal parameters of a CMAC network, which can minimize the learning error between the desired output and the CMAC network's as well as the number of memory used in the CMAC network. Computer simulations demonstrate the effectiveness of the proposed design method.

There is more than a single quality characteristic and they are often of varying or mixed target types. The purpose of this paper is to develop general strategies for solving the multiple response robust design problem. The desirability function provides an important tool to solve problems that have different types of target since the desirability values all the range between zero and one. Several combinations of arithmetic averages, geometric averages, and standard deviations are used in the various strategies to find the best design point.

Drivers' sitting strategies are considered in car seat design. Existing research has identified representative sitting strategies by visual inspection of seating pressure measurements collected from a small sample size of drivers. The present study recruited 20 female and 20 male participants, measured seating pressure, and classified sitting strategies by cluster analysis. The participants' sitting postures were classified based on seating pressure distribution into mid-back and scapular, mid-back and lumbar, and lumbar sitting strategies for the upper body and hip concentrated, hip and mid-thigh concentrated, and hip and mid-thigh distributed sitting strategies for the lower body. The effects of gender and occupant package layout (OPL) on sitting strategy were nout found significant. The identified sitting strategies would be of use for the design and evaluation of an OPL and a seat.
