The performing art represents joy, anger, sorrow and pleasure through acting and dance, and is told to be a composite art represented by make-up, setting, costume and props. Therefore, it can be said that make-up is an important medium of stage art. Make-up in stage art is a kind of communication with audiences through understanding personalities of characters as demanded by scenarios. Due to the creative stage make-up which meets the character in the play relevant to these contents of the play, the conceptual study on stage make-up design for visual expression coincide with the intended character is needed. In this study, I investigate theoretical, universal, and psychological personality types by analyzing basic appearance features based on the physiognomy(face-reading) related from the psychological theories. And visualized through illustration according to personality types to apply for the characters in the play.

The D-optimal design for the nonlinear model typically depends on the unknown parameters to be estimated. Therefore, it is strongly recommended in literature to use a sequential experimental design for estimating the parameters. In this paper two stage experimental design is discussed under many different circumstances including estimating parameters. The method is so universal to be applied to any mixture of objectives for any model including linear model. A hybrid approach is suggested to handle more than 2 objectives in two-stage experimental design. The design is discussed in approximate design framework.

It is essential to consider geometry in the early design stage for rational design decisions. However, a crucial decision had been taken by conversation, physical model, and gesture rather than BIM mode which can analyze geometry efficiently. This research proposes the framework of interaction between BIM model and physical model for real-time BIM analysis. Through this real-time system framework of two models, architects can adopt BIM data at early design stage to review analysis of BIM model. It should facilitate dynamic design based on rich BIM information from an early stage to a final stage.

In this study, a novel systematic design procedure by Genetic Algorithm of a two stage relief valve is proposed. First of all. a mathematical model describing the dynamics of a balanced piston type relief valve has been derived. Governing equations such as dynamic equations for the main spool and the pilot spool and flow equations for each orifice are established. The mathematical model is verified by comparing the results of simulation with that of experiments. Furthermore, influences of the parameters on the dynamic characteristics of a relief valve have been investigated by simulation of the proposed model. Major design parameters on the valve response are determined, which affect the system response significantly. And then, using the determined parameters, the optimization of the two stage relief valve by Genetic Algorithm, which is a random search algorithm can find the global optimum without converging local optimum, is performed. The optimal design process of a two stage relief valve is presented to determine the major design parameters. Fitness function reflects the changing pressure according to parameters. It is shown that the genetic algorithms satisfactorily optimized the major design parameters of the two stage relief valve.

This Research suggest that key features of lighting simulation and intuitive theaterical design method can unify single system. It can produce the virtual scene of stage which is able to predict the number of lighting box and design budget. the final goal of this research is unifying lighting and stage design into on single system.

The main objective of this paper is to propose the optimal design method of forging process using genetic algorithm. Design optimization of forging process was doing about one stage and multi stage. The objective function is considered the filling of die. The chosen design variables are die geometry in multi stage and initial billet shape in one stage. We performed FE analysis to simulated forging process. The optimized preform and initial billet shape was obtained by genetic algorithm and FE analysis. To show the efficiency of GA method in forging problem are solved and compared with published results.

This study aims to understand the importance of stage costumes, examine and analyze their theoretical ideas in order to propose new designs and support the studies and advances of stage costumes in play. The writer operated and produced the costume designs of Shakespeare's play, Measure for Measure as a costume director, which was played on September 16 to 17, 2011 at the Haneul Theater in the National Theater of Korea and on September 3, 2011 at the Jinnam Munye Theater. The study was followed by 1. Proposing a new modern point of view of the design of the traditional dresses in 16th to 17th centuries. 2. Expressing a symbolism based on personality, role and nature of characters in the play by a creative and modern image of the dress in color, line, and silhouette, which are basic factors of a clothes design.

The purpose of this study is to present the suitable material that can be a real help to make the creativity development teaching method for creative inspirations of fashion design. To achieve these goals, researched and analyzed the creativity studies in the fields of psychology, education, and design (visual design, product design, fashion design, etc.) published in the national journal. Through this analysis, were extracted the characteristics of creativity, teaching methods for creativity learning, and expression methods. Based on this, intend to provide the creativity characteristic, the expression method, and the problem solving process in teaching methods for promoting fashion design ability. After the analysis, the results are as follows; First, the classical 4P (Place, Person, Process, Product) is important to a creativity development teaching method for fashion design. The elements of creativity of a creativity development teaching method for fashion design are 5elements; curiosity, openness, originality, patience, and synthetic ability. Second, the typical method is a drawing (such as a sketch) when visually express and embody ideas in fashion design. Drawing is an important activity that is working with the right brain and the left brain. Drawing exercises will reduce the burden of expressing ideas, providing pleasure and fulfillment in the development of creative ideas. Third, offered 5stages to solve problems of a creativity development teaching method for fashion design; understanding stage, idea stage, visualization stage, evaluation stage, and verification stage. Abstract intangible ideas are concreted and elaborated through stages of visual manifestation such as language, symbol, and drawing.

We present a micro-positioning stage that has minimized geometrical error and can drive in the 4-axis. This stage divided into two parts: $Z\theta_x$ $\theta_y$, motion stage and$\theta_z$ motion stage. These stages are constructed in flexure hinges, piezoelectric actuators and displacement scnsors. The dynamic model for each stage is obtained and their FE (finite element) models are made. Using the Lagrange's equation, the motion of equation is found. Through the parametric analysis and FE analysis, sensitiv~ty of the design parameters is executed. Finally, fundamental frequencies, maximum stress, and displacement sensitivity for each stage are obtained. We expect that this micro-positioning stage be a useful micro-alignment device for various applications.

Recently the design of multi-stage gear drive is being highly concerned. Until now, since the researches of gear drive are focused on the design for satisfying safety factor, the reliability evaluation of multi-stage gear drive is not included. In this paper, the life and reliability models of multi-stage gear drive are proposed using methods of probability and statistics. The life and reliability of the multi-stage gear drive have been evaluated, which is based on the life and reliability of each stage gear drive. The pinion and gear lives of each stage are calculated using the Lundberg-Palmgren theory and the Weibull failure distribution. These lives are combined using methods of probability and statistics to produce a life and reliability model of multi-stage gear drive.
