Urban outdoor playground serves as the space to promote the physical, cognitive, social, creative, emotional and linguistic development of children and the education center to stimulate the imagination and curiosity of them. It is also the place to be used as a basic park for urban residents and the local community space for associating with people of various levels. However, this playground as a banal space did not function properly before now. In 21st century, urban playground requires change and its various changes have been attempted. In particular, there is a need for the change into eco-friendly playground to provide children's health and urban healthy environment. Therefore, it requires much effort to construct and vitalize the eco-friendly playground adequate for domestic circumstances in Korea. This study derived the preferred planning items among eco-friendly playground planning elements focused on the people to use it and provided the data for the construction of local friendly, eco-friendly outdoor playground. For this purpose, we visited the playground of the apartment house built in 10 years with more than 300 households and surveyed 200 adults and investigated the residents' utilization and satisfaction on the current playground and the recognition and preference for eco-friendly playground.

An attempt has been made to prove the so-called 'feature accumulation theory'. It is the theory describing that people tend to feel the same space with more identifiable objects much larger than that with fewer objects. Applying this theory to our cognition of spatial size, this paper made an experiment. Students were asked that if the lecture room they are sitting becomes a module (module 1), then how large are the questioned spaces in the campus. The result was striking. Through the mental image processing, they answered that the library and the architecture building looks much smaller than they actually are, and more surprisingly the basketball field much more smaller than it really is. This experiment shows that there is a strong tendency by which people regard the space much larger when there are more occupiable or behavior-causing elements in the space. In the case of basketball field, since there is nothing that can be occupied, this open space is seen as a small space for the subjects. This line of cognitive perception can be applied to the practice of urban planning and architectural planning. With the same size of given space, we can make it feel more rich and larger.

The beauty of Korean architecture is in its natural beauty. Traditional residence of Korea is architecture that expresses modesty that is embraces the nature. Hanok is designed based on understanding of the nature and responding to it. For this reason, Hanok is a nature-friendly residential space. There are many unique traits of Hanok and one of them is that it is built based on scientific principles. Hanok, without using modern technology and machines, utilizes effectively the natural environment and the climate, e.g., the sun and the wind. Hanok, based on Korea's geographical condition and climate characteristics, have produced a variety of residential houses. The principle of Hanok is not to challenge the nature but embrace and accept it. Furthermore, in Hanok is embedded Korea's traditional philosophy and ideas and it is not simply a simple residential space but also a place for meditation and spiritual training. As the time passes, there are more researches are being done to enhance health in addition to traditional role of protection and convenience. Accordingly, more efforts are being made to bring the nature into human life. Hanok, the traditional residential form of Korea, has environment-friendly architecture and characteristics that could promote human health and enhance our life. Therefore, the nature-oriented philosophy and environmental elements of Hanok should be more systematically studied to take advantage of its architectural advantages and create healthier modern residential culture.

New Zealand appears to be a water rich country; however there are considerable water allocation issues. Mostly these revolve around balancing environmental concerns with economic development. The largest economic sector is agriculture which currently utilizes around 80% of the allocated water and has considerable potential to increase in size. The resource management framework that New Zealand has developed over the past twenty years revolves around local decision-making and sustainable management principles. As the demands for water have grown there has been growing concern that this framework is inadequate to deal with the issues of declining water quantity and quality through agricultural intensification. In Canterbury, the region with the highest water allocation and demand, a new approach is being trialed. The Canterbury Water Management Strategy (CWMS) recognizes the need for: ecological restoration for past damage; infrastructure development for increased irrigation; and the need to link infrastructure with more efficient use of water by both existing and new water users. These three elements are recognized as having equal value. The CWMS builds on the local decision-making concept but is deliberately aimed at consensus building in order to remove expensive and adversarial resource management hearings. It is practical enough to recognize that economic development is needed but that it need not proceed in conflict with the environment, but rather can be a means towards environmental improvement.

As environmental problems and water-shortage phenomenon become a global issue, many states look for the effective method to use water resources. So, decentralized rainwater management is recognized as a new water management system that rainwater can be infiltrated and used on-site. But it is little difficult to build a park, lake, and forest for evaporating rainwater in city because the land price of city is very high. In order to build an excellent infiltration system for a dwelling and a park in Korea, KICT has developed Linear infiltration system. This infiltration system is consist of first flush treatment, storage and infiltration, overflow control system. These elements are connected closely and working as a combined system. A storm sewer can be changed by the linear infiltration system. This study is to make design guideline using Linear infiltration system in apartment house. So ATV-DVWK-M13, FLL and present condition of Korean rainwater system were analyzed and the guidelines direction were set up. Through this study, a foundation is prepared to build the decentralized rainwater management of apartment house.

The library is the most frequently utilized building on campus, but, it has been reported to be a facility most vulnerable to crime. However, almost no study has been conducted on crime in the library, which implies a need for research on the subject. The purpose of this study is specifically twofold. First, this study will suggest components of environmental plan to prevent fear over library crime on campus. Second, the study seeks to reveal the correlation between use per library space and fear of crime. This has been analyzed by conducting a survey among current university students, and the survey includes the following three details: first, fear over day/night crime per library space; second, components of environmental plan to prevent fear over crime per library space; third, level of use per library space on campus. The results of study show that fear of crime has low relation with crime occurrence, fear per library space is higher during the night than during the day, and the space where the fear level is usually high is the service facility. There is a difference for each space in terms of important components of environmental plan to prevent crime per library space, and installation of security device is most important. One must consider a plan for a crime safe environment regarding library space where the level of use during the day is low.

Although aspiration towards quality of life and holistic health has been growing faster in our modern society and the affordance of health in built environment has been more acknowledged, there has been hardly any development on built environment planning and design theory that can be comfortably and confidently used in creating built environment to promote holistic health. Thereby, this study sets out to experimently formulate a composite theory that explains the relationship between health and built environment. The main methodology of this study is literature review and analysis. Theories that have been applied in other similar fields were chosen to be analyzed by health related perspectives and graft those theories onto holistic health viewpoints to compose a comprehensive theory. Selected theories that were considered useful to be analyzed were Lawton's Environment Press Theory, Carp & Carp's Complementary & Congruence Theory, Valins' Activity-based Design Criteria Theory, Atchley's Continuity Theory, Murtha & Lee's User Benefit Criteria Theory, and Alexander's Pattern Language Theory. Characteristics of these theories were compared by their abstractness and concreteness, and the range of application, and analyzed by a holistic health perspective. Then, these theories were comprehensively structuralized and synthesized as a built environment for health theory. This study has its significance in providing a base to develop healthy built environment research further as it introduced a conceptual framework which explains spatial elements in the health functionality point of view.

BIM based design methodology requires more information than traditional design methodology in order to insure efficiency throughout the project. BIM based design not only requires all building data in the form of 3D shapes, but also all other relevant data regarding building components. Information is typically grouped in a standard classification system such as by standardized material names. The development of a domestic BIM based standard classification system is yet to be created and deployed in the industry. Each designer is specifying their own building information classification systems which is causing inconsistency in the industry. Therefore BIM based designs, are causing confusion in the industry as each designer follow no guidelines for material standardization classification. The lack of information regarding this in the BIM template will continue to cause confusion about a projects building information data consistently. This study is that of preliminary research to develop a BIM template. First, overseas BIM templates were analyzed regarding BIM standards and documentation. Examination then followed regarding the element and characteristics needed for the development of a BIM template, a suggested hierarchy of elements required for a BIM template were then made. The result of this research is that it will be used to develop a "BIM template prototype", to support the generation of building information data regarding neighborhood facilities.

Today the realization of a welfare society is urgently needed as growing of economy. To promptly meet the needs of the times, the ratio of a matriculation of the physically disabled is getting higher, stretching opportunities of a higher education. But, the walk environment in university educational facilities is still insufficient because of the indifference to the education of the physically disabled. The purpose of this research is to suggest the direction to improve the walk environment for all users through evaluation of the accessibility of the walk environment in university educational facilities, and the scope of the research is the internal and external walk environment of university educational facilities. The first step of the research is preparatory study review to extract the elements of the accessibility of the Universal Design Principles. And then, we evaluate the accessibility of university educational facilities through the site visits. The results of this research are as following: 1) The internal and external walk environment of university educational facilities needs more physical improvement for keeping accessibility. 2) We need to provide consistent guidances from the external sidewalks to main entrances, slopes, staircases, elevators, and corridors. 3) The walk environment of university educational facilities needs to maintain continuously.
