  • As the environmental pollution is intensified, the interest in the conservation and quality of global environment is also increasing. Interior design affects on environmental conservation as well as the quality of outdoor and indoor environment through all phases of interior design. Therefore, interior designers should do environment-friendly design. The purpose of this study was to examine the consciousness and application degree of environment-friendly interior design in actual project by interior designers. The study was conducted by a questionnaire survey. The subjects were 215 interior designers working in Seoul area. The major findings of this study were as follows: 1) The 33 representative elements of environment-friendly interior design were selected and categorized into 5 fields: resources and materials, energy savings, ecological environments, indoor environments, and space effectiveness. These would be useful to carry out environment-friendly interior design projects and related researches. 2) Many interior designers didn't understand what the environment-friendly interior design is correctly, even though they were interested in it. Therefore, the educational program of environment-friendly interior design should be developed. 3) Even though interior designers thought most elements of environment-friendly interior design very important, they didn't apply them well to actual projects.

  • Since Seoul city supplied 'Sangsang Children's Park', domestic children's parks are changing from formal facilities to creative play space recently. From eco-friendly safe playground model development project, the awareness of eco-friendly playground, namely children's park is increasing and its necessity is magnified. However, we could not know how well most children's parks aimed at the eco-friendly playground reflect eco-friendly features and whether they are eco-friendly or not because there are not the specific planning guidelines and evaluation standards for making the eco-friendly playground or children's park. Therefore, in this study we established the environment-friendliness evaluation standards of children's parks and estimated the environment-friendly features of the 9 parks built on the subject of green among Sangsang Children's Parks. In the observational survey of the 9 parks, we evaluated the environment-friendliness of these parks in the 8 fields(location and placement, ecological environment, play space, play equipment and facilities, additional facilities, materials and resources, energy saving, environmental load reduction) according to the levels(suitable, partial reflection, unsuitable, non-reflection) of reflection of eco-friendly planning factors. The assessment results showed that 4 items (location and placement, additional facilities, play space, play equipment and facilities) were suitable and others (energy saving, environmental load reduction, ecological environment, materials and resources) were partial reflection or unsuitable. Therefore, on the basis of these results, this study proposed the planning indicators to be considered first and the planning factors that should be complemented and improved in the construction of eco-friendly children's park in future.

  • In 2000s, the interest of ROHAS has been increased and the environmental problem has begun to be discussed as the environmental and global value, not the individual perspective. And the standard of value for eco-friendly awareness has been expanded to the economic category. The trend of eco-friendly fabric can be divided into 3 periods depending on the property. The period for natural fabric with visual effects(2002~2004) can be summarized as the creation of natural shape using the natural image, the interaction of cotton and the technology from the visual perspective. In the period of functional conjunction with eco-friendliness and technology(2005~2008), the eco-friendly awareness through the conjunction of technology and nature and the re-cycling, and the responsibility to the environment had been increased. In the period of sustainable development for nature and environment(2009~2011), it showed the conjunction with nature and the integration with technology and eco-friendly issues. Therefore, the characteristic of eco-friendly trend in fabric since 2000 can be said; firstly, the high-quality fabric has been developed with technological development for the functional progress. Secondly, the ethical creativity has been displayed with the development and utilization of eco-friendly recycling materials. Thirdly, the materials reflected with eco-friendly issues have emerged.
