Nowadays, flooding wast is serious problem to mankind and the endeavour for solving waste problem is performed in connection with environmental problem and natural resource problem. In Korea, there are a lot of movements related to reduction of waste, too. As the solution of these problems, recycling is recommanded and many kinds of recycling technique are devised. In America, military has been playing an important role in recycling area for a long time. This paper is the survey of several articles and working papers about America military's recycling research. We investigated the recycling of water, construction and demolition wastes etc. These research results are very important in real field of military. It is considered our military has to prepare this recycling problem and now it's the right time. All of these can be adapted to our military, commercial companies and civilians through some modification. We suggest that our military should cope with recycling problem more deliberately.

Once-used $CO_2$-silicate bonded sand from domestic foundry is mostly discarded in a reclaimed land because of its bad collapsibility and reproduction properties. So this causes serious environmental problem. We can get 82% recovery of silica from used sand by scrubbing reclamation process in this research. When we repeat the reclamation-recycling of the foundry sand, artificial silica sand is broken down below 2-cycles, but natural silica sand does not destroyed when used repeatedly more than 10-cycles and have a good property of recycling with little change of its size.

To develop a Mg-Zeolite for simultaneous recovery of the N and the P from sewage water, the natural zeolite was treated with 20% $MgCl_2$ solution by changing the pH the temperature and the treating time of the solution. And the contents of Ca Fe Na K Mg of Mg-Zeolite were analyzed by ICP. The optimum treatment condition for Mg-Zeolite was induced to pH 7.0 $50^{\circ}C$ in 20% $MgCl_2$ solution and for 80min treatment. And the Na and the K ions in natural zeolite are significant factors for Mg exchange in the zeolite.

This study was executed to deduce the factors affecting eco-friendly behaviors and attitudes, to analyse the difference of eco-friendly behaviors and attitudes between countries, and to draw the variables affecting clothing recycling behavior. The sample comprised people from the UK, China, South Korea. The results were as follows. The four factors related to eco-friendly behaviors and the five factors related to eco-friendly attitudes were derived from the results of factor analysis. In the case of eco-friendly behaviors, four eco-friendly behavior factors showed a significant difference all according to gender and country. In the case of eco-friendly attitudes, saving of natural resources for eco-friendly life, recycling for eco-friendly life, and individual preference for eco-friendly life showed a significant according to gender, also recycling for eco-friendly life, individual preference for eco-friendly life, social awareness for eco-friendly life, and company's awareness for eco-friendly life showed a significant difference according to country. All of the variables related to clothing recycling behaviors showed the significant difference according to gender and countries. It was verified that the stronger the behaviors or attitudes for waste recycling and environmental protection, individual preference for eco-friendly life, saving of natural resources, buying eco-friendly products, and separate collection for recycling, the more positive the action to clothing recycling. The results of this study will be helpful to establish a marketing strategy for each country and to deduce a plan to attract clothing recycling form people.

Currently, the global atmosphere around the world is altering at a very rapid pace. Among those changes, some are beneficial, but most of the changes are lead to destruction to our planet. The area of environmental science is a significant resource for learning more about these changes. Due to the urbanization, the human population is increasing, natural resources becoming very limited. To solve the limited resources issues, recycling is absolutely an alternative source for the new demands and limitations. Recycling education is very important to raise awareness among students and their communities about the need for recycling and what materials are recyclable locally. In this paper, we reported the role of sustainability science and technology and the impact of recycling research education in the middle schools, both in developing countries and Asian countries and also we included the brief data of global recycling of waste.

최근 경제성장 및 국민 생활향상에 따라 폐기물 발생량이 급격하게 증대되어 그 처리문제가 심각해지고 있다. 이러한 폐기물중 노고 포장의 해체 및 유지·보수공사의 증가에 따라 다량 발생하고 있는 폐아스콘은 대부분 재활용되지 못하고 불법처분 또는 매립되고 있어 자원낭비 및 심각한 환경오염 문제를 야기하고 있는 실정이다. 따라서 본 연구에서는 폐아스콘의 재활용을 촉진하기 위하여 이동형 아스팔트 재생기 및 재생첨가제를 사용하여 양질의 신재 아스콘과 동등 수준의 품질을 갖춘 기층용 재생아스콘을 제조하기 위한 기초적 연구를 수행하였다.

As the scarcity of natural resources has become apparent, the recycling industry has emerged as a promising one for its growth potential. Yet, the recycling industry still remains undeveloped and inefficient for various reasons. In this study, we focus on firms' recycling processes to understand the current status of recycling firms' value creation activities. With respect to the adopted recycling processes, we empirically investigate the differences in firm characteristics and firm performance. We use the data from Keco (Korea Environment Cooperation) which annually conducts a survey of recycling firms in Korea. We exclusively consider the whole group of plastic recycling industry in order to control for a possible bias in firm performance, stemming from the heterogeneity in processing and recycling of materials other than plastics. We review the descriptive statistics from the sample firms and conduct a series of hierarchical regression analyses. The results show that most of the firms in this industry adopt physical transformation processes with a low-level technology. These firms with physical transformation processes are smaller in size and produce entry level items which do not secure higher margins. The results indicate that the recycling industry largely comprises low value added firms which lack economies of scale and resources for R&D. For the stable growth of the industry, recycling firms must create sustainable values through implementation of technology-driven processes and improvement in product quality. In addition, the government should help build a reliable reverse logistic network, lower the entry barriers, and provide necessary funding for the SMEs in the recycling industry.

Fasciclin II (FasII), the Drosophila ortholog of neural cell adhesion molecule (NCAM), plays a critical role in synaptic stabilization and plasticity. Although this molecule undergoes constitutive cycling at the synaptic membrane, how its membrane trafficking is regulated to ensure proper synaptic development remains poorly understood. In a genetic screen, we recovered a mutation in Drosophila mical-like that displays an increase in bouton numbers and a decrease in FasII levels at the neuromuscular junction (NMJ). Similar phenotypes were induced by presynaptic, but not postsynaptic, knockdown of mical-like expression. FasII trafficking assays revealed that the recycling of internalized FasII molecules to the cell surface was significantly impaired in mical-like-knockdown cells. Importantly, this defect correlated with an enhancement of endosomal sorting of FasII to the lysosomal degradation pathway. Similarly, synaptic vesicle exocytosis was also impaired in mical-like mutants. Together, our results identify Mical-like as a novel regulator of synaptic growth and FasII endocytic recycling.
