Activated Rice-Hull carbon was developed to remove ammonia compounds in water matrix. Isotherm adsorption tests of ammonia were conducted using a bottle-point technique and column test. Residual ammonia after Jar-Test or passing through the column was determined by Indophenol method, and assessed the removal efficiency for ammonia of the adsorbent. As a result, the adsorption capacity for ammonia of activated racehull carbon was very larger than that of coconut shell carbon, because the rice hull carbon had the higher BET surface area of silicate. The activated racehull carbon is under the development as adsorbent to remove ammonia in drinking water and waste water.

The objectives of this study were to investigate the need for school uniform recycling and to review the school uniform recycling-related education. 231 female high school students were asked to answer regarding the wearing state of school uniform and their satisfaction level. 10 subjects in middle school technology/home economy were evaluated. As the result, the students wore 1~2 pieces of school uniform, which showed that it was hard to keep them clean by washing them often. The satisfaction level of school uniform was not high, The lowest item was the price. Therefore, to increase the satisfaction level of the school uniforms and also to increase the sanitary level of the school uniforms, it was advisable to purchase a recycled school uniform at cheaper prices to have an extra set. For a vitalization of the recycled school uniforms, the middle school technology/home economy subjects were reviewed. In the topic of "clothing acquisition plan and purchase", the themes of planned purchase, overconsumption of clothing and environmental pollution were discussed and included preferable behaviors for disposal. The topic of "clothing manufacturing and recycling" listed recycling the clothes that are not worn or exchanging them with neighbors as well as suggesting methods to illicit environment-friendly behaviors and carrying them out. However, some textbooks only briefly explained the methods of recycling and more detailed and practical methods need to be suggested in the curriculum. In addition, the contents regarding the environment in the clothing topic need to be supplemented more and more changes, such as related education plans or data development, are required.

The purpose of this study was to investigate young children's environmental literacy level and variables that affected their environmental literacy. Of the students, 969 in third grade from big cities, medium sized cities and rural areas participated in this study, and their environmental literacy was measured through 69 questions consisted of 24 items for knowledge, 22 for attitude, 16 for behavior, and 7 for skills with 13 demographic variables. Eighty minutes were given to answer the questions. Statistical analysis was conducted on each of the categories (knowledge, attitude, behavior, skill) that make up environmental literacy and multivariate analysis variance (MANOVA) was also conducted to investigate variables that affect environmental literacy. Results indicated that the correlation between attitude and behavior is the highest. Also, it was found that a demographic variable might affect one, two, or sometimes all categories of the environmental literacy.

The purpose of this study was to analyze and compare Korean middle school-level environmental education(EE) textbooks. More specifically, these analyses and comparisons were designed to explore the extent to which environmental investigation skills were addressed in these EE textbooks (i.e., curriculum inclusion), as well as the manner in which these skills were to be taught and learned (i.e., instructional approaches). To analyze EE textbooks, the researchers developed a 'Curriculum Analysis Chart' that include six skill clusters and four instructional strategies. This analytic chart permitted the researchers to determine which skills were featured in selected textbooks, as well as which skill-oriented instructional strategies accompanied each of those skills. The chart was revised several times through pilot analyses. Using the final version of this chart, the researchers analyzed and then compared the three textbooks. This analysis indicated that the Korean middle school-level EE textbooks were designed to support conceptual learning and understanding of environment and environmental problems/issues (i.e., content-oriented), and were designed to support skill learning to a moderate degree. On the basis of textbooks analysis, the researchers offered several recommendations for future research, and for educational practices in EE.

본 연구는 예비 초등 교사들의 환경에 대한 태도를 조사하고 이러한 태도에서 비롯된 환경 관련 인식이 학교환경교육에 주는 시사점을 도출하는 것을 목적으로 수행되었다. 연구의 결과, 예비 초등 교사들은 경제적인 성장 내지는 과학기술의 발달이 환경에 미치는 부정적인 영향과 환경보호의 필요성은 비교적 올바르게 인식하고 있는 것으로 나타났다. 그러나 이런 인식과는 대조적으로 삶의 질의 저하에 대하서는 매우 두려워하고 있으며 이는 환경문제에 대한 인식이 실천적 지식으로 연계되고 있지 못함을 보여준다. 아울러 예비 초등 교사들은 환경 문제에 대해 균형감이 상실된 편향된 태도 및 인식 경향을 보이는 것으로 조사되었으며, 이는 이들의 환경에 대한 태도 및 지식이 대개 대중매체를 통해 형성되었기 때문인 것으로 사료된다. 따라서, 예비 초등 교사들이 환경에 대하여 균형 있는 태도를 갖추고 이와 연계된 올바른 인식을 형성하며, 이것이 실천적 지식으로 연계되기 위해서는 학교 교육을 통한 체계적인 환경교육이 필요함을 시사하였다.

The convergence progress in science technology and ensuing changes in educational environments require another huge change in education programs in the 21st century defined as a knowledge-based information society. But nowadays, prospective college students are increasingly avoiding natural science and engineering. So, educational fields in korea need suitable convergence educational programs (STEAM: science, technology, engineering, arts, mathematics) for creative competent person who is training and experiencing. In addition, environmental design fields are predicting about spread of Kinetic architecture. Therefore the aim of this study is developing convergence hand-on educational program which is incorporate robot science into environmental design for children. The program and teaching materials were developed by mapping between robot science and environmental design process leading the Design Promote Committee in KIID(Korea Institute of Interior Design) supported research teams in Hansung University. And then, For utility of the program, we had a 3 times of demonstration of empirical education. First, graduate students of design and robot major, and small group of children who are selected, at last, 63 children who are applying the program randomly. For more high quality program, we were conducting survey of post-empirical education evaluation for children and their parents. In conclusion, we found out highly satisfaction of the program those two groups. Also they need more organized places, time, task and so on. And the convergence educational program would develop by systematic approach and empirical research. At last, various and series convergence programs and teaching materials would develop creative competency based for regular and irregular courses of whole educational period.

A blast furnace slag(BFS) has been used as a filter medium for the treatment of domestic waste waters during the period of 9-month. More than 90% of phosphorus was removed while the hardness of the treated water increased by 5 times and the pH was significantly raised from 6.8 to 10.8. The high hardness and pH of the treated water indicated dissolution of BSF by the sewage. The experimental results suggest that BFS could be utilized for the removal of phosphorus in the waste water treatment plant using aquatic plants and gravels.
