In this study, to investigate the effect of the generalized performance curve on the performance prediction and to find the optimal ones, a systematic study is performed. For this purpose, we compared the influence of the stage performance curves with experimental data in multi-stage axial compressors. As a result, it is discovered that the optimal generalized performance curves vary according to the number of the stages in compressors. And we found that for a low-stage compressors, Muir's pressure coefficient curve gives the best prediction results at design rotational frequency regardless of the efficiency curve. On the other hand, for high-stage compressors, Stone's pressure coefficient curve gives the optimistic results about the performance prediction at design rotational frequency.

The design of multi-stage gear drives is a time-consuming process because it includes more complicated problems, which are not considered in the design of single-stage gear drives. The designer has no determine the number of reduction stages and the gear ratios of each reduction stage. In addition, the design problems include not only dimensional design but also configuration design of gear drive elements. There is no definite rule or principle for these types of design problems. Thus the design practices largely depend on the sense and the experiences of the designer, and consequently result in undesirable design solution. A new and generalized design algorithm has been proposed to support the designer at the preliminary phase of the design of multi-stage gear drives. The proposed design algorithm automates the design process by integrating the dimensional design and the configuration design process. The algorithm consists of four steps. In the first step, the user determines the number of reduction stages. In the second step, gear ratios of every stage are chosen using the random search method. The values of the basic design parameters of a gear are chose in the third step by using the generate and test method. Then the values of the dimensions, such as pitch diameter, outer diameter and face width, are calculated for the configuration design in the next step. The strength and durability of each gear is guaranteed by the bending strength and the pitting resistance rating practices by using AGMA rating formulas. In the final step, the configuration design is carried out using simulated annealing algorithm. The positions of gears and shafts are determined to minimize the geometrical volume (size) of a gearbox while avoiding interferences between them. These steps are carried out iteratively until a desirable solution is acquired. The proposed design algorithm is applied to the preliminary design of four-stage gear drives in order to validate the availability. The design solution has considerably good results in both aspects of the dimensional and the configuration design.

A 150 m$\^$3//hr, 30 kg/cm$\^$2/, air-cooled 3-stage reciprocating air compressor is designed to be used in starting large diesel engines of ships. A basic design procedure is presented to meet the targeted pressure and flow rate, and especially a volumetric efficiency of 80%. Temperature and stress analysis of the 1st stage cylinder are performed using axisymmetric FEM modelings. The dynamics of valve system is analyzed and stress at the 1st stage valve seat caused by valve impact is evaluated. To reduce friction loss and wear at the compressor engine system tribological design issues are reviewed and good design practices are suggested. Finally, forced-air pin-type interstage coolers are designed to dissipate generated compression heat at each stage.

For decades, we have filled our theme parks, shopping malls, a streets and etc. with complementary or competing medias. These spaces have remedied newspapers, magazines, radio, TV and film or have been the object for remediation. Because there has been no remediation in traditional theatrical stage design, many problems come along with the design, which makes audiences hard to feel the sense of presence. It's time to have systematic research to find a way out for the solution of traditional theatrical stage design. This study suggests the solutions for remediation of traditional theatrical stage design, so we are going to research with laying emphasis on the cooperative works between the fields of theatrical stage design and the Visual Effects par that forms extensive and diverse portions. The proposal for remediation of traditional theatrical stage design with practical use of Visual Effects will create economical higher value-added through the systematization of close and cooperative work between the fields of Visual Effects and theatrical stage design. In addition, the systematization of the cooperation of these two parts will make another communicative paradigm that audiences have never been able to experience before in traditional theatrical stage design.

This research verified efficiency of 2 design process models; 2-stage model and 3-stage model. 2-stage model means subjective and sensitive design process based on designer's creative mind. Contrarily, 3-stage model means objective, logical and consumer-oriented design process. Past researches have suggested inconsistent conclusions on efficiency of 2 design process models. This study suggested efficiency of 2 design process model based on the concept of market leader strategy and market seeker strategy. The study results imply that, in condition of high prestige brand, 2-stage model based on market leader strategy is more effective and contrarily in case of low prestige brand, 3-stage model based on market seeker strategy is more efficient. However, it is requested to perform various investigation about situations in which each design process model is more effective for the generalization of the study results.

The main purpose of (the) performing arts is to efficiently communicate the themes and meanings which performances contain under limited time and place to the audience. Stage design should visually express play writer's scripts and director's interpretations of works, amid limitations. Although it is mostly designed metaphorically, in many cases, it is used only as a tool describing the background of performances but fails to effectively convey the true message of scenes to spectators. On the other hand, Bob Crowley has been recognized for his own design presentation skills to win 'Best Scenic Design of a Musical' of Tony Awards for six times and still exerts great influence on the musical and performing arts fields as a set designer. This study analyzes his reading of scripts and visual metaphor expressions, focusing on the musical, 'Aida' where the skills are mostly notable. To that end, we studied the concept of stage arts and theory of visual metaphoric expression to derive the features of his own technique in visual metaphor. Then, the features were applied to each scene of 'Aida' to see how they are displayed on stage. The result shows that Bob Crowley not only describes the background on stage, but also visualizes characters' personality and emotions in scenes. Such method of his expression is a proof to enhanced performance level by maximizing the atmosphere. Considering that a stage design should be based on the capacity of a designer to reinterpret the space with renewed viewpoints, visual metaphoric expression can serve as an effective tool to deliver clear messages to the audience under limited time and space, which is open to various methods of expressions.

As urbanization increases in UAE, the demand for housing and infrastructures also grows. The challenge is to continue to build but in a different way considering more energy-efficient sustainable buildings. Producing a sustainable design is highly dependent upon effective participation among the diverse parties involved. In the construction industry in the UAE, these parties are fragmented due to the multistage nature of construction projects and multidisciplinary participants, particularly during the design stage. The decisions made during this stage have an extensive impact on subsequent stages of a project's life cycle. Having a sustainability expert during the design stage is important and the awareness of sustainability requirements by all design participants is of equal importance. In this research, recent advances in information technology are used to develop an information model that will improve the sustainability of building during the design stage. An information framework for storing design information and sustainability performance criteria is developed, allowing design participants to collaborate in an integrated environment. This research is expected to help designers produce sustainable designs for building projects.
