  • Ultra-fine fibers are spun by expensive fiber spinning technology using special spinnerets. Ultra-fine fibrous materials have attracted considerable attentions because of their potential applications as high performance wiping cloths, water absorbent sound proofing materials and moisture transfer sporting good. However, production expense of ultra-fine fibers is 5 to 7 times higher than general textile materials. The objective of this research is to develop cost-effective recycling process to produce multi-functional ultra-fine fibrous material in terms of the development of garnetting and carding machines for ultra-fine fibrous material waste and scrap. The efficiency of sound absorption for the recycled polyester nonwoven increased with decreasing length and thickness of component fibers, which was attributed to the reduction of air permeability. It is expected that high value and cost-effective textile products are developed using ultra-fine fibrous wastes and that sound proofing material and oil absorbent f

  • The purposes of this study were to categorize of pro-environmental clothing purchasing and disposal behaviors and to identify impacts of health and environment consciousness on pro-environmental clothing purchase and disposal behaviors. The subjects were homemakers (n=381), and they were segmented into LOHAS group, environment conscious group, unconscious group, and wellbeing group according to their health and environment consciousness. Older homemakers were included in LOHAS group and environment conscious group. And these homemakers performed pro-environmental clothing purchasing and disposal behaviors better than wellbeing group or unconscious group. Health consciousness was positively related with the second-hand clothing purchasing and recycling. Environment consciousness was positively related with clothing made with organic, natural or functional materials, or the second-hand clothing purchasing, and recycling of the second-hand clothing. There was a need to develop continuing education programs to strengthen homemakers' health and environment consciousness, or to upgrade their pro-environmental clothing purchase and disposal behaviors.

  • Conclusion and the improvement plan according to the survey on recycling wastes in 'the program of woman and environmental education' mainly for the chairwomen of the women's association of the apartment house in City and County of Chungchongnamdo during the first half of 1998 (from March tp April) are as follows. 1. Conclusion 1) It showed that the rate of recognition for recycle has no difference by regional groups and the rate of recognition is 57.4% but they mainly know vaguely or they do not know. 2) It showed that the rate they do not know how the separated wastes are recycled is 30.4% and the scope of their knowledge is approximative.(52.6%) 3) It showed that it is the housewives who mainly do the separate garbage collection (72.7%) and 19.1% of the people have no interest in the separate discharge. 4) It showed that the rate they filter the garbage or remove water from the garbage at house is 53.1%. And 20% of the people in the urban region dump untreated wastes but 8.5% of the people in the rural region do the same, so the rate of using garbage in the rural region is higher than that in the urban region. 5) It showed that the separate state of the garbage is 29.2% for the removal of toothpick and paper and 47.4% for the removal of vinyl and stopper. 6) It showed that 66.7% of the motive for recycling waste is the education activity for environment by the women's association and SAEMAEUL association and 34.5% of that is the influence of TV and radio. 7) It showed that the rate of making compost and feed using garbage in the rural region is higher than that in the urban region and in some urban regions, the rate they sprinkle the garbage in provisional compost state on the floor garden is high. 8) It showed that the recognition rate for the material of separately collected garbage corresponding to the separate waste system of 5-6 classification is 12.5% 9) It showed that the major variable which has an effect on the recycle is the education activity for environment by the neighborhood meeting(P<0.05) and by the women's association of saemaeul activity(P<0.05)

  • This study is aimed to systematize the contents of environmental education in the home education and to develop the environmental education. For this, this study firstly examined the characteristics and goals of home education and its relation to environmental education. Secondly, in the paradigm of environmental education this study analyzed the goals and contents of environmental education in the domain of home education which is included in the practicum subject of the 7th curriculum. Thirdly, this study examined the effective teaching and learning methods for home education and the considerations in organization of textbook contents which reflect these teaching and learning methods. Finally, this study suggested an example of textbooks which reflect all these considerations. It has been found out that: (1) the home education is based on the recognition of environmental problems related to home life, (2) the home education explains the environmental problems, and (3) the home education has its goals of acquring active attitudes and skills to solve these problems. In the teaching contents, the home education was analyzed to have the following concerning environmental education: the utilization of resources for food, clothes, and housing and home life, that is, the domain of ‘environmental sanitation’ related to food ingestion and sanitary life, the domain of ‘sound consumption life’ related to the utilization of resources and their consumption, and the domain of ‘environmental pollution’ on the prevention of every kind of pollutants in the home life. However, the environmental education in the home education according to the 7th educational curriculum has the distinctiveness from the contents of environmental education which were emphasized in the past home education. The distinctiveness are as following: (1)the resources matter is dealt with in the aspect of recycling various resouces from home life, (2)the prevention or reduction of pollutants in life which take the considerable part of environmental pollution is emphasized, (3)children's sensitivity In environment is emphasized to be developed, and (4)the importance of life is emphasized to be taught.

  • Under the WTO system, global standardization of professionalism in architecture practice calls for transformation of curriculum in architectural education in Korea. This paper compares the curriculum standards of international accrediting authorities such as NAAB and RIBA based on UIA accord which defines fundamental knowledge and abilities of an architect. As a result this paper extracts 51 achievement oriented criteria of architectural education in Korea. It can be categorized as communication, design, cultural context(history and theory, human behavior and social aspects), technical systems(structural systems, environmental control systems, construction material and assemblies) and practice(project process, project economics and business management, laws and regulations). Based on this recommended Korean curriculum standards, current curriculum is analyzed focusing on the 5 architectural programs in Seoul. Through this analysis, it became clear that some area - social and economic aspects in architecture, sustainability in architecture, understanding and selection of construction material, assemblies and environmental control system, recycling of existing building, professional liability, professional rules of conduct, project economics and project management - need to be covered and emphasized to meet the international standards in professional education in architecture. The result in this paper will be used as a basic data in the process of finding the direction of restructuring curriculum for professional architectural education in Korea.
