(Background)In modern industrial society, the design industry failed to observe the law of nature, destructing it. Regardless its intention, the design industry destructed the environment so that it can't maintain the future life because of waste and disaster. For the purpose, it is important to adopt the technology to reuse the waste resource generated by building or minimize the damage to environment for the resource that can't be recycled. (Methods)On the assumption that the material and resource can be an alternative plan for the design that can make environment be sustained, the study analyzed materials and resources out of superior office space of USA, which were selected by LEED Green Building Rating System. (Results)The analysis result revealed that all cases reused main structural part of existing building and indoor and various materials were reused or recycled. Especially, the materials without or with low amount of VOCs and formaldehyde were used. In order to reduce construction waste, the finish of existing building was exposed as it was, 50% of reused materials were used or disassemblable materials were used. When regional materials are used, there is an advantage to reduce transportation cost and recycle the materials rapidly. Lastly, the environment-friendly certified by FSC was used in all cases. (Conclusion)After all, the material is one of the space design strategies sensitive to environment so it is important to select good material. Harmless, environment-friendly materials applied to sustainable office space contribute to the creation of healthy environment. In addition, the use of recycled materials and reused materials to minimize waste is also essential factor for creating sustainable space.

There are various form of public elements in modern urban space. These public elements mingle with sociocultural elements which consist of each city, determining urban environment's image. Especially, since the social value of design becomes important, the social role of public design has been emphasized as an effective value for public interest and environment. It is just about 10 years since design mind in the public sector has been made domestically. Even though domestic public design has been studied not so long, it has developed with radical change of social culture and science technology. This study targets public environment in modern dense urban space. Also, it grasps the trend of public design studies through analysing and documentary survey of the existing studies, and based on that result, aims at presenting the direction that domestic public design studies should progress. This study selected 253 theses(1989.6~2015.11) by collecting primary, secondary data about public design studies, and implemented overall meta-analysing about the trend of domestic public design studies. As a result, public design has been studied intensively in the field of design about environment, architecture, etc. The trend analyzing of study purpose and keyword has a tendency which is weighted towards exploratory study focused on suggestion and development about object and realm of public design. The trend analyzing of study area tends to study overall part of public space or public facility rather than specific area and object. The most parts of studies analyze domestic area, especially Seoul metropolitan area. Also, the study method weighted in favor of some qualitative analysis has been utilized.

A research to evaluate the efficiency of design optimization was carried out for aerodynamic design optimization problem in distributed computing environment. The aerodynamic analyses which take most of computational work during design optimization were divided into several jobs and allocated to associated PC clients through network. This is not a parallel process based on domain decomposition in a single analysis rather than a simultaneous distributed-analyses using network-distributed computers. GBOM(gradient-based optimization method), SAO(Sequential Approximate Optimization) and RSM(Response Surface Method) were implemented to perform design optimization of transonic airfoils and evaluate their efficiencies. dimensional minimization followed by direction search involved in the GBOM was found an obstacle against improving efficiency of the design process in the present distributed computing system. The SAO was found fairly suitable for the distributed computing environment even it has a handicap of local search. The RSM is apparently the most efficient algorithm in the present distributed computing environment, but additional trial and error works needed to enhance the reliability of the approximation model deteriorate its efficiency from the practical point of view.

The fields of green building and ecological design have much to offer to those who are seeking to improve the ecological impact of schools and school grounds. These well established disciplines are particularly useful to existing schools considering renovations to make them more energy, water, and resource efficient as well as healthier places to work and play, Green building and ecological design principles and techniques are also very effective, of course, if incorporated into the design for brand new school buildings. The major concept of the Eco-school plan is to understand that the school consists of an ecosystem, so the design concept should focus on minimising impact but at the same time maintaining close contact with the environment. T his is becoming the basic concept in applying the Eco-school design to the new 21st century school building. This thesis is an analysis on the methods of application, based on careful examination of case-studies from the U.S.A about detailed plan element and design method, through the following six aspects ; (1) site use plan, (2) green plan, (3) water system plan, (4) materials and recycling of resources, (5) energy use plan, (6) indoor environment plan.

Wearable computer focuses on functional aspects of fashion to respond to and satisfy needs for daily availability of ubiquitous environment owing to ever-developing digital technologies. The purpose of this study is to examine in possible developmental direction of wearable computer and thereby explore more promising directions of wearable computer to enhance its adaptability to future advanced ubiquitous environment and also satisfy both esthetical and functional needs. Now the wearable computer can be classified broadly into 3 types in the aspect of functionality, i.e. computer containing 'integratability', 'convertibility' and 'interactability'. Beyond simple portability concepts based on digital devices attached on body, it will be necessary that follow-up studies on wearable computer satisfy needs for enhanced digital functionality to comply with ubiquitous environment as well as emotional needs inherent in clothing. It is expected that possibility of future wearable computer will be extended via collaborative relationships between design and functionality, and should be implemented through possible points of contact among computer, telecommunication, design and fashion. Based on the findings of this study, it is expected that follow-up researches and developments for wearable computer to meet both functionality and esthetical values in the aspect of 'fashion design combined with electronic products' will help assure the variety of fashion designs for wearable computer contributing to better life quality of human in future ubiquitous environment.

The purpose of this study is to analyze minimalism in the environment-friendly aspect and to suggest methodology of environment-friendly fashion design. The results of this study are as follows. First, it is possible to create newly fashion-designed goods by re-arranging used goods. This method is environment-friendly, in that it recycles resources and simplifies production process. It can also meet the sense of beauty of consumers by reviving the intrinsic beauty of the used goods. Second, When we produce brand new fashion-designed goods with used goods as raw materials, the new ones reflect specific characters of the used goods which originate from their own times and regions. In this way, this method can be a fashion design which accommodate multi-cultural trends. Third, it is possible to produce goods designed by inspiration from a human body. This fashion-design method includes several ways, such as usage of human body silhouette, composition of colors using natural dyeing, and usage of natural materials. Recognizing a human being as a creature interacting with the nature can broaden range of imagination in design methodology.

The simulation of water balance was conducted for suggested four alternative multi-layer cover design of near-surface radioactive waste disposal facility under domestic climate condition. The analysis was also conducted for the most favorable one out of four alternative cover design under conservative scenarios. Until 100 years after closure of disposal vault, the infiltration flux for the most favorable cover design was negligible even under doubling of the ambient precipitation condition. When the degradation of asphalt and geomembrane after 100 years of closure was considered, the infiltration flux significantly increased almost to the design criteria of cover system in I' Aube disposal facility. And it was found that the hydraulic conductivity of bentonite/sand as a bottom barrier should be no greater than 1$\times$10$^{-7}$ cm/sec recommended by U.S. EPA.

Purpose: The purpose of this study was to identify the role of the physical environment in task interruptions in the healthcare settings. Many dangerous events such as airplane crash and medical errors are the result of human errors and, these errors are often the result of interruptions during a critical task of professional workers. In fact, the physical environment that determines accessibility and visibility among people affects interruptions significantly, but architectural studies have given little attention to the management of interruptions. Methods: Therefore, the researcher reviewed research literature in other fields to find out how the physical environment affected interruptions. Many studies were from management, human factors, and health care, but few from architecture. First the author examined the impact of interruptions, second described the social context of interruptions and the role of the physical environment. Results: Findings included that description of the physical environment was not very clear in studies from management and human factors, while little work had been done on interruptions in architecture. The author proposed study design that compensated shortcomings of each field by combining approaches from management, human factors, and architecture. Implications: Unit design strategies such as distributed nurse stations can affect interruptions and layout analysis such as space syntax analysis can evaluate visibility and accessibility of floor plans in the preliminary design phase.
