  • Modernity which is superficial phenomenon set off the mass scale for mass consumption and provide uniformly artificial environment. But natural destruction, environment pollution, resources exhaustion and so on has been caused by this and now ecology is threatened by destruction and damage beyond the limitation and human beings survival is even threatened. Accordingly furniture development for environment preservation considered environment problem is the urgent real situation. Recent paradigm is the concept of Eco-design which is the green design possible to live together in symbiosis, and new types of alternative furniture are needed in Korea as well. 'Furniture for disassembly' is presented as new method for alternative furniture.

  • It was shown in the previous study (Lee and Bertero 1993) that incremental collapse can lead to the exhaustion of the plastic rotation capacity at critical regions in a structure when subjected to the number of load cycles and load intensities as expected during maximum credible earthquakes and that this type of collapse can be predicted using the shakedown analysis technique. In this study, a minimum-weight design methodology, which takes into account not only the prevention of this incremental collapse but also the requirements of the serviceability limit states, is proposed by using the shakedown analysis technique and a nonlinear programming algorithm (gradient projection method).

  • Recently, owing to the deterioration of reconstruction and the construction, much of the construction waste is discharged in our construction field, and the amount of construction waste are rapidly increased. These waste are raised to financial and environmental problems, so the method of reusing waste concretes has been studied and carried out many direction. Especially being want of resources, if waste concrete could be recycled as aggregate for concrete, it will contribute to solve the exhaustion of natural aggregate, in terms of saving resources and protecting environment. This study is that the floating properties of concrete with recycled coarse aggregate were investigated for the substitution of recycled coarse aggregate. The result of this study, in case of water reducing, the property of harden concrete for the substitution ratio of recycled coarse aggregate was increased. The Quality of recycled coarse aggregate concrete was improved by water reducing.

  • In this paper, we propose Neuro-Fuzzy discrimination method of the new and old bill using bill money acoustic data. The concept of the histogram is introduced to improve the processing time into the proposal system. The adaptative filter is used in order to remove the motor sound from an observed bill money acoustic data. The output signal of this adaptive digital filter is converted into not only a spectrum but also a histogram. It became easy that features of the paper money sound were extracted from the bill money acoustic data. The spectral data and the histogram is obtained like this, and it become an input pattern of the neural network(NN). Then, the discrimination result of the NN is finally judged by the fuzzy inferece in the new bill or the exhaustion bill.

  • Recycle fashion is suggested to the suitable alternative of the environmental problem and the exhaustion of natural resources. The purpose of this study is focused on trying to comprehend between design characteristics and aesthetic values of recycle fashion design and those from fashion brands, fashion designers, and the public. For such purpose, 1553 photos of recycle fashion design which appeared in web-site, newspaper, fashion magazines between 2002 and 2007 were analyzed. Method of analysis did content analysis. The results of the research can be summarized as follows. First, design characteristics of recycle fashion were expressed by Junk Recycle Look, Vintage Recycle Look, Contemporary Recycle Look, Artisanal Recycle Look. Second, the expression methods of recycle fashion were presented reuse, reform, and regeneration. Third, aesthetic values of recycle fashion can be explained by the promotion of environment, the variableness, and the deconstruction.

Especially being want of resources, if waste concrete could be recycled as aggregates for concrete, it will contribute to solve the exhaustion of natural aggregate, in terms of saving resources and protecting environment. This study is that the mechanical properties of concrete with recycled coarse aggregate were investigated for types of mineral admixture and the substitution of recycled coarse aggregate. The result of this study, in case of using mineral admixture, the property of fresh concrete was rised. And the property of harden concrete for the substitution ratio of recycled coarse aggregate was decreased. But the property of concrete with mineral admixture was better than that of concrete used only cement.

  • Purpose: The purpose of this study was to explore the lived experiences of new graduate nurses in personal life and in clinical setting during their first year. Methods: Eleven new graduate nurses were interviewed and the data were analyzed using the Giorgi's phenomenological method. Results: The main results of this research were negative experiences such as poor nursing skills, inability to enjoy personal life, physical exhaustion and health problems, and uncertainty of nursing values. On the other hand, there were some positive aspects on their minds: adjustmental/developmental needs, sense of responsibility, receptive capability, and proficiency with their work. They gradually found themselves being endured and changing to adapt. Conclusion: Transition from students to staff nurses is a very stressful experience for new graduate nurses. It may negatively affect their personal lives as well. However they tried to keep themselves positive to overcome their difficulties. It is necessary for them to be given time, a systematic program, and a supportive environment to adapt.

  • Recently, as the national policy of green growth is promoted, construction field also makes an effort to reduce CO2 gas released when producing cement continuously. In other words, as the method solving environmental pollution and resources exhaustion, lots of mineral material compounds such as blast furnace slag powder which is industrial by-product, fly ash, red mud, etc. are examined to bo used as the substitute good of cement Therefore this study is to investigate the hardening characteristics of alumino-silicate inorganic binder using red-mud used as a accelerator of industrial by-product such as fly ash and blast furnace slag powder according to curing temperature. As a result, it is effective to use red-mud as the accelerator of inorganic binder with other additory accelerators.

  • Some phthalimidyl azo dyes containing N,N-diethyl or N,N-di($\beta$-methoxycarbonylethyl) group have been attempted to apply onto two kinds of polyurethane based materials and rationalize their dyeability and fastness comparing with those of some commercial disperse dyes. Phthalimidyl azo dye showed 66~98% of exhaustion yield at $120^{\circ}C$ by a conventional exhaust dyeing method. The dyeings were found to have a higher wash fastness with both fabrics in comparison with those of commercial dyes which indicates lower thermomigration and efficient alkali clearable properties of phthalimidyl ring and/or diester group during post-dyeing process.
