The purpose of this study is to emboss the importance of safety education by recognizing the instructor's thoughts on safety and the prevention of safety accidents of early-childhood through the examination, analysis of the education site of safety at early-childhood education facilities. The subject of this were 120 early-childhood teachers in the Jeonbuk areas. The data were collected using questionaries and analyzed by the statistical methods of frequencies. ANOVA with SPSS pc program. The research questions were as follows; 1. What is the understanding of early-childhood teachers on safety recognition? 2. Is there a difference in the understanding of the teacher on safety and the management of the education curriculum on safety education that is being taught at early-childhood education facilities? The main results and solutions of this study were as follows: 1. In order for early-childhood teachers to teach safety education in early-childhood education facilities, they must join a safety mutual aid association or join an insurance policy to furnish an appropriate compensation system. Also, safety education must be systematically taught at a $social{\cdot}national$ level so that teachers and young children can have an understanding on safety under the support and concern of early-childhood education facilities and administration authorities. 2. Results on the comparison of the understanding of safety education and management of actual education of teachers on the actual conditions of the education curriculum of safety education show that although teachers are aware of most items of safety education but the actual education was not being taught. This means that although the teachers are aware of the importance of safety education, the actual education is not being taught.

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. This implies that alternatives for activating them are needed.
