  • The purpose of this research is to verify the effect of a 3-year-old's green growth education knowledge of environmental conservation and eco-friendly attitude. This study conducted a survey of 2 classes of 3-years-old children (totaling 45 children) located in Gyeonggi Province Shiheung. The experimental group consisted of 23 children while the comparison group was comprised of 22 children. Experimental treatment period was 5 primarily by the classroom teacher in the experimental group and 12 sessions going green growth program was compared to a group, the basic curriculum was operate as usual. The results of this research are summarized as follows. First, the result of the experimental group, which participated in green growth and did not participate in the control group, show that the early childhood of the experimental group has been improved about knowledge of environmental conservation and showed a statistically significant difference. Second, the result of the experimental group which participated in green growth show that the attitude of the experimental group improved an infant's environment-friendly conscience.

  • The aim of this study is to develop an eco-friendly reduction process of indigo as an alternative choice. Hansenula misumaiensis was used and their reducing activity toward synthetic indigo as well as natural indigo was estimated by dyeing test in terms of indigo dye uptake. The changes in K/S value and pH were monitored on the time-based measurements. Also, reduction duration was evaluated. On the basis of the results described in this study, it was confirmed that Hansenula misumaiensis reduced indigo. Reducing power of Hansenula misumaiensis reached to maximum in two days. It can be possible to develop eco-friendly process of indigo reduction using Hansenula misumaiensis by the optimization of strain culture conditions and the optimization of reduction conditions.
