There have been worldwide efforts to develop environmental-friendly transportation systems, which aim to solve the environmental issues such as pollution with the traffic congestion in downtown. For some developed countries, environmental indicators to estimate their environmental performances as well as eco-design technologies in the field of transportation have been already secured. In Korea, however, relatively fundamental studies which are insufficient to calculate quantitatively the environmental impacts have been performed. In this study, the life cycle assessment was introduced as one of methodologies to evaluate environmental performance and reduce environmental impacts of a bimodal tram system throughout its entire life cycle, including design, manufacture, operation and disuse steps.

Optimal remediation design using the pump and treat(P&T) method and natural attenuation was accomplished in consideration for degradation processes, such as sorption and first-order decay rate. Variation of both sorption and first-order decay rate has influence on design of optimal remediation application. When sorption effect increases, the more pumping rate and pumping wells are required. The location of operated wells is on the centerline of contaminant plume and wells near hot spot are mainly operated when sorption effect increases. The higher of first-order decay rate, the less pumping rate is required. These results show that the degradation processes have to be considered as one of the essential factors for optimal remediation design.

This study deals with the expressive characteristics of Installation Art and their applicability to environmental design, and as such, aims to specify a artistic methods from the contemporary art. What Installation Art is search of in their works is "the state of relationships" which is "to replace the concept of form with that of structure, and the concept of space with that of the environment" that is, the terms of relations in the overall environment of time and space. Installation Art essentially relies on a multiplicity of forms and attitudes leading to projects which positively make use of "spatial-temporal process" to reaffirm and "problematise" their open-endedness manifest in complex contextuality and shifting temporality. This study presents a new interpretation of spatial-temporal dimension, site-specificity, and intermedia art that we find in Installation Art and tries to combine that new artistic insight a with environmental design to provide a basis for integrated art. This study places a great emphasis on the interdisciplinary approaches to the environment we inhabit, which I hope will contribute to generating a greater number of creative possibilities for environmental design.

A gradient-based evolutionary optimization methodology is presented for finding the optimal design of viscous dampers to minimize an objective function defined for a linear multi-storey structure. The maximum value along height of the transfer function amplitudes for the interstorey drifts is taken as the objective function. Since the ground motion includes various uncertainties, the optimal damper placement may be different depending on the ground motion used for design. Furthermore, the transfer function treated as the objective function depends on the properties of structural parameters and added dampers. This implies that a more robust damper design is desired. A reliable and robust damping design system against any unpredictable ground motions can be provided by minimizing the maximum transfer function. Such design system is proposed in this paper.

The current trend in shipyard industry is to reduce the weight of ships to support the reduction of CO₂ emissions. In this study, the stiffened plate was optimized that is used for building most of the ship-structure. Further, this study proposed the hybrid Genetic Algorithm (GA) technique, which combines a genetic algorithm and subsequent optimization methods. The design variables included the number and type of stiffeners, stiffener spacing, and plate thickness. The number and type of stiffeners are discrete design variables that were optimized using the genetic algorithm. The stiffener spacing and plate thickness are continuous design variables that were determined by subsequent optimization. The plate deformation was classified into global and local displacement, resulting in accurate estimations of the maximum displacement. The optimization result showed that the proposed hybrid GA is effective for obtaining optimal solutions, for all the design variables.

As society and culture becomes complicated and diverse, so do the ensuing problems. The symptoms from the stress there was mainly focused on the adult group, however, now, they are shown in children. So the play therapy attracts attention as a way to cure stress. This study is intend to analysis an environment of play therapy space which would play an active role during treatment through the understanding of children's playing behavior. Disable children's playing therapy and pattern should be considered in the playing environmental design, and their feelings also need to be considered. The cozy and relaxed environment is important to children, so that they can have a natural interaction with the environment during the therapies. Output the factor of environment for play therapy and suggest the space of play therapy which fit on it.

I investigated the relationship between social support, environmental factors, and color design within the public spaces of healthcare facilities. Through a comprehensive literature review and case studies from major hospitals in the United States, the United Kingdom, and Scotland, I explored how these elements contribute to public spaces' overall concept and function. The study emphasizes the need to establish a clear relationship between the social functions of these spaces and their physical and environmental characteristics. By examining theoretical frameworks and observed examples, I analyzed the impact of color design and the integration of internal and external spaces. The findings highlight that well-designed spaces, especially those utilizing effective color schemes and connecting indoor and outdoor areas, enhance user satisfaction and support healing processes. The results underscore the importance of communal spaces in healthcare facilities for psychological and social healing. I conclude that these spaces should be intentionally designed to foster social interactions among patients and visitors by improving pedestrian accessibility and incorporating social support structures.

After the "Landscaping Law" was enacted in 2007 Korea, national and local governments has been responding swiftly by seeking various methods. Seoul Metropolitan City and other municipalities have established "Seoul Coloring and Systematization" project, which analyzes and extracts the humanities, humanities and natural environments in 2007 as an opportunity to recognize the importance of environmental color. However, it is necessary to slightly supplement the color scheme created by the observer's concept. In this way, you have to find the color of the environment in a city where real life takes place. The city's environmental color has the concept of "walking" as the basic human behavior. Because the average speed is 4km, it differs from that of a vehicle that travels more than 60km per hour. Also, most of the frontage zone is used except for special cases. Therefore the characteristics of the environmental color and frontage zone on the road side were concluded in this paper as Single Type, Connection Type, and Extension Type. In addition, the principle of environmental color of city was established by the change of texture according to space of time and the characteristics of urban scale, and new media characteristics were found in various interactions. The results of this study suggest an environmental coloring strategy for workability such as hue continuity, hue harmonization and integrated design.
