The stage facilities in the western culture originates in the scientifically planned Open Air Theater built in BC 3C and magnificent theaters built in the era of Rome. These buildings are the remains that reveal popularization of the play. Furthermore, the facilities continued to flourish in the medieval to the Industrial Revolution as stage art actualizing designers' imagination. Diverse systems developed in industrial technology have been transferred to the stage, and the balance between industrial and cultural art has been endeavored to be achieved. The conversion methods of the stage has been developing in various forms. Domestic stage setting arrangement techniques and material exploitation have also been developing. Therefore, in reality, it is very difficult to grasp the definite trend. Additionally, as for the stage system in Korea, plays are dependently directed by directors and stage artists. It is concluded that the current state should be understood based on actual examples to meet solve these problems. The purpose of the study is to provide basic data for stage facilities planning. To do this, how the stage system of large performance halls can be used in accordance with performance condition of the grounds in Korea and frequent scene changes is given a special attention. With this background, the surroundings of the stage and conversion system are examined.

As the definition and role of design changes over time with the times and society, design education needs to update teaching methods to match it. The course design in this study began with an optimisation of the learning model based on previous research and analysis, followed by in-depth interviews, the application of the interview results to the final curriculum design, and finally a questionnaire to verify the positive effects of this teaching model. This teaching model has been applied to teach a pilot class in a university of applied sciences in China. The main characteristics of the course design are Project-Based Learning (PJBL) oriented, team cooperation centric, and an educational model developed based on peer assessment. In every stage of the UI design course, realistic project simulations are adopted, enhancing students' abilities through practical experience, teamwork, and peer assessment. The innovation lies in validating the effectiveness and advantages of this model at every stage of the UI design course, innovating existing teaching methods, optimizing learning models, and combining practice with evaluation. This research found that a project-oriented team course design based on PJBL has a high degree of effectiveness and relevance in each stage of the UI design course, significantly improving students' overall competence. It is expected that the results of this study can be applied in various ways to the course design of the courses that similar to design majors.

The purpos대 f this research was to figure out clothing imagery underlying Shakepeare's King Lear and transfer it into actual stage costume. Three steps were taken in order to achieve the purpose . The first step exemined theoretical background of the Shakepeare's imagery. The second step reviewed a wide spectum of stage costume used in the last four centuries. The final step was to design and produced actual stage costume focusing on Lear, while considering clothing imagery drawn from the previous steps. King Lear contained rich clothing imagery which could contrast the relationship between material and spirit. In particular, it shed light on the contrast between Lear's divesting and Edgar's wearing and denoted that wearing and divesting processes were closely related to spiritual and status changes. A review of stage costume used for four centuries was prepared in order to understand how clothing imagery was applied in producing stage costume. It was found that their stage costume was reflecting clothing imagery captured from the analysis of king Lear. On the basis of this review, this research presented Lear's stage costume which applied clothing imagery drawn from King Lear. In producing stage costume , actual stage costume used Elizabethan fashion as its basic color and pattern. It also utilized modern clothing production techniques and ornaments acceptable in these days. As Lear was depicted as a character who underwent spiritual and status changes in the process of divesting , his costume was produced in line with this clothing imagery (i.e., divesting). The long journey of reviewing and analyzing King Lear from a stand point of clothing reassured us, on the one hand, the importance of stage costume. On the other hand, it established the groundwork for developing the methodology of fashion design by applying clothing imagery drawn from literature to design and production of stage costume.

The foremost criterion in the design of a Satellite Launch Vehicle(SLV) is its performance capability to boost the designated payload to the desired mission orbit; it starts from focusing on the SLV configuration to achieve the velocity requirements($}\Delta}V$) for the mission. In this paper we review an analytical approach which is suitable enough for preliminary conceptual design and is used previously to optimize stage configurations for Two Stage to Orbit SLV for Low Earth Orbit(LEO) Missions; we have extended this approach to Three Stage to Orbit SLV and compared different propellant options for the mission. The objective is to minimize the Gross Lift off Weight(GLOW). The primary performance figures of merit were the total inert weight of the SLV and the payload weight that the SLV could lift into LEO, given candidate propulsion systems. The optimization is achieved by configuring the $}\Delta}V$ between stages. A comparison of configurations of single-stage and multi-stage SLVs is made for different propellants. Based upon the optimized stage configurations a comparative performance analysis is made between Liquid and Solid fueled SLV. A 3 degree of freedom trajectory-analysis program is modeled in SIMULINK and used to conduct the performance analysis. Furthermore, a cost analysis is performed on our stage optimized SLVs. The cost estimation relationships(CER) used give us a comparison of development and fabrication costs for the Liquid vs. Solid fueled SLV in man years. The pros and cons of the production, operation ability, performance, responsiveness, logistics, price, shelf life, storage etc of both Solid and Liquid fueled SLVs are discussed. The statistics and data are used from existing or historical(real) SLV stages.

Detention pond has an important role in peak flow reduction to mitigate flood damage. Design of detention pond is accomplished through the preliminary stage, planning stage, and design stage in general. New development projects produce increased peak flow and flow amounts. In this case it is necessary to design the detention pond easily and simply. The simple procedure of detention pond design is proposed in this study. The relevant variables are peak flow ratio ($\alpha$) for the before and after development, and storage ratio which is ratio of storage volume to flow amounts. Simplified method for the detention pond design with runoff reduction is easily used for practical purposes.

Finite element analysis of a multi-stage deep drawing process is carried out for the die design of rectangular cup drawing with the large aspect ratio. Simulation is performed for thorough investigation of unfavorable mechanisms in the initial design. The analysis reveals that the difference of the drawing ratio and the irregular contact condition produces non-uniform metal flow to cause wrinkling and severe extension. In this paper, the modification guideline is proposed in the design of the process and the tool shape. The analysis result confirms that the modified design not only improves the quality of a deep-drawn product but also reduces the possibility of failure.

Conventionally design for multi-stage cold forging depends on the designer's experience and decision-making. Due to such non-deterministic nature of the process sequence design, a flexible inference engine is needed for process design expert system. In this study, A* searching algorithm was introduced to arrive at the vetter process sequence design considering the number of forming stages and levels of effective strain, effective stress, and forming load during the porcess. In order to optimize the process sequence in producing the final part, cost function was defined and minimized using the proposed A* searching algorithm. For verification of the designed forming sequences, forming experiments and finite element analyses were carried out in the present investigation. The developed expert system using A* searching algorithm can produce a flexible design system based on changes in the number of forming stages and weights.

At design stage of the TRXI agricultural tractor transmission (New product of TongYang Moolsan Co., Ltd), the noise and vibration of the transmission were analyzed theoretically for the optimal design of the transmission . For this analysis, the finite element model was developed using a commercial computer software, ANSYS. The noise and vibration of the TRXI transmission housing were predicted by the modal analysis. Natural frequency of the TRXI transmission housing was ranged from 12.53Hz(1st mode ) to 30.05Hz(5th mode). The fifth mode took place at the bearing metal in the area of rear transmission housing and was very close to the gear mesh frequency (30.5Hz) of low rang gear at the low creep shifting . Based on the results , the bearing metal of the range shift housing was reenforced with the rib at design stage.

Artificial neural networks(ANN) have been exploited where the relationship among information is very complicated and nonlinear. It is appropriate to computerize the information and knowledge used in the preliminary design stage where it lacks of formality of representation of designers' experience and intuition. However, most designers start the preliminary design stage with very little information. Therefore, the ANN model for this stage must be designed to have input much less than output. This case usually causes big troubles such as in learning time, convergence and reliability of solutions. To address this problem, this paper proposes multi-level neural networks for progressive structural design considering that all the design information can not be obtained at a time but are growing gradually. The use of multi-level networks developed in this paper has been proved its validity by applying it to the preliminary design of cable-stayed bridges.
