This study was done to provide a case model with a concept of environmental integration based on the water circulation system. Area of interest (AOI) is the Eastern Pangyo New Town area, which has several advantages in adaptation of a water circulation system. The AOI has a potential of maintaining water resources, and has a good condition to construct the water circulation system. Research done for the purpose of the establishment of the water circulation system in the Eastern Pangyo New Town shows the following. The main sources of water supply in the water circulation system in the Eastern Pangyo New Town is from two subway stations and runoff water, along with the natural water flowing from the mountains, rain water, and stream water. It was determined that more than 35,000 tons of water would be needed for the creation of water circulation system at the Eastern Pangyo. If the creation of infrastructure for the use of runoff and rain water as well as the periodic management can be provided, it can serve as the new model for a new city with water circulation system. In addition, since the Eastern Pangyo New Town water circulation system can secure enough amount of water resources, natural drainage system (NDS) in which it can be in dry condition in non-rainy days, is applied and connected to the typical waterways. Such water circulation system has many positive aspects including the wise use of water resources, and providing wild Life animals corridors and habitats. Also, the water circulation system can lead to the environmental education to the residents and visitors on environmental awareness of the water circulation system and their environment.

The present study suggests a concept of resources circulation type agriculture and a concept of a livestock zone related to it and evaluated economical efficiency about a possibility of the resources circulation type livestock zone based on the concept. As a result, when the resources circulation type livestock zone is operated in an area of 1,300ha, it was evaluated that the profit of 11,244 hundred thousand won per year is generated, compared to the conventional agriculture. When light and heat expenses and roughage of Hanwoo production, production of TMR forage as well as income of the energy and composting business of livestock manure at the recycling center were considered in addition to that, it was judged that the present zone development bushiness has enough business feasibility. However, it is necessary that the support regulations, etc. is constructed so that all produced compost byproducts are used at farmhouses and the system related to facility investment assurance and assistance of operating expenses is maintained. It is thought that the complement of a system is also necessary so that energy or power generation expenses can be operated in the same conditions as other new & renewable energy, and the nation's purchase of carbon credits(CDM) is investigated and systemized in the early period, and construction of a revitalization plan of the business through budget securing of the Ministry of Agriculture and Forestry related to the trade of CDM and carbon emission rights is also a business that should be urgently developed. In the future, the change of an outside environment will further promote use of the energy. Also, as people, who don't know agriculture. farm village, increase day by day because of population concentration in a city, an opportunity that can new added value through experience tourism or educational programs utilizing them is increasing. Accordingly, if programs utilizing social characteristics, such as utilization as a space of tourism. leisure. experience, system construction of bio-energy and system construction that Micro Grid or Smart Grid as a dispersed storage and generation system is stabilized, are constructed, it can be said that revitalization or success conditions of the zone is further achieved.

This study carried out hydraulic model test for water circulation system in Cheongna district as part of Incheon Free Economic Zone. Canal way project of Cheongna was planned to establish for environment-friendly water circulation system, improve quality of life and diversification of traffic through using boat as a water-friendly international business city. The navigation canal, There are two intake facility in central park and it can purify water 15,000$m^3$ per day. After purify, water move to 8 facility of water culture area which supplies water in canal way. This process called water circulation system in cheongna. Also, there are several flow induction machine in canal way except south-north way. Therefore, this study will verify about validity of water circulation system's safety through hydraulic model test.

2016년 5월, 제19대의 마지막 정기 국회에서 "자원순환기본법"이 제정되었다. 본 법은 향후 우리나라의 자원순환 정책의 큰 방향성을 제시하여야 할 최상위의 기본법이므로 그 파급력을 고려하였을 때 법의 취지, 주요 내용, 정책적 방향성을 심도있게 분석하고 이해할 필요가 있다. 특히, 2018년 1월부터 본 법이 시행될 예정이므로 이 법의 원래 취지인 자원순환사회로의 전환을 효율적으로 지원할 수 있도록 법률 체계 및 내용을 제대로 갖추고 있는지 살펴볼 필요가 있다. 또한, 하위법령 제정 시 그 내용이 편향되지 않도록 이해관계자들의 적극적 참여를 통한 심도있는 협의가 이루어져야 할 것이며, 조항별 구체화된 법안들이 도출되어야 할 것이다. 따라서 본 연구에서는 자원순환기본법의 체계 및 주요내용 검토를 통해 문제점을 파악하고, 법률의 실효성을 극대화하기 위해 하위법령 제정과정에서의 주요 조항별 논점과 구체적 시행방향에 대해 검토, 제시하고자 한다.

The purpose of this study was to evaluate the effect of implementing a Liquid Manure Circulation System (LMCS) on the environmental improvement of swine farms. Bacterial counts at different circulation phases of the LMCS were measured. Air in the swine facility and the liquid manure in each step of LMCS were sampled and gaseous composition detected in swine farms both with and without LMCS to compare the environmental conditions in either case. There were no differences in the total bacteria count at any circulation phase in the LMCS. Escherichia coli were detected at a very low abundance only at the outlet of the slurry pit ($1.5{\times}10^2CFU/m{\ell}$). Salmonella were not detected at any phase. The LMCS clearly affected the odor strength of the swine farm and improved the air quality in the swine facility. On-site odor strength - inside, at the exhaust, and at the border of the swine facility - were clearly lowered in farms applying LMCS. Furthermore, the levels of ammonia, hydrogen sulfide, and carbon dioxide were improved in swine facilities applying LMCS.

기존 사례조사를 바탕으로 국내의 구리에 대한 물질흐름 분석을 Up-stream과 Down-stream으로 구분하여 실시하였으며, 2010년 기준 폐기물로 배출된 이후의 폐기 재활용 흐름에 대해서 현장조사를 통한 분석을 실시하였다. 배출 이후의 물질흐름을 배출 및 수입, 수거 및 폐기, 자원회수, 제품생산 및 수출의 4단계로 나누어 각 단계별로 분석했다. 재활용 단계에서 36.8%의 자원순환율 도출 되었고, 이를 바탕으로 각 단계별로 자원순환율을 증진시킬 수 있는 여러 방안을 제시하였다. 배출 및 수입 단계에서는 지정을 세분하여 적절한 경우 이를 폐기물 자원으로 분류할 것을 제안하였다. 이런 폐자원에 대해서 할당관세를 적용을 제안하였다. 수거 및 폐기 단계에서는 부과세 편취 해결과 입찰제도의 개선을 통한 수급 안정화 방안을 제시하였다. 자원순환단계에서는 전문적인 파쇄 및 분쇄 업체를 육성방안과 대기업과 중소기업간의 상생방안을 제시하였다. 제품생산 및 수출 단계에서는 현재 구리스크랩 재활용 상황에서 재활용 활성화를 위해서 폐기물 처리시설의 등록 면제 요청하고 있으나 이보다는 폐기물 처리시설로 등록을 위해서 필요한 모든 인허가를 통합적으로 처리하는 방안을 제시하였다.
