Resources circulation logistics factor has come to be one of the most important concerns in today's business due to the need for conscious use of limited resources and the greenhouse effects. The purpose of this study was to propose strategic approaches to improve firm's competitive advantages by exploring the logistics practices that increase firm's logistics performance and reduce environmental problems at the same time. In doing so, we reviewed past literature on Resources circulation logistics factor, logistics operation level, and firm's logistics Performance, and then developed a conceptual model and researchable hypotheses, Survey data were collected from manufacturing companies to test the hypotheses. Survey data included the variables of Resources circulation logistics factor, logistics operation practices, and firm's performance. Firm's performance was measured by customer service and logistics costs.

Environmental problems are becoming hot issues in many countries and the role of the enterprise, which causes environmental contamination, has become one of the most important concerns in business. We consider the factors such as reduce, recycle, reuse, which is effected environment conscious logistics system, and then we are to suggest optimal directions through statistical analysis of effects and causes of the influences of environmental logistics activities on logistics performance. In order to attain this objective we simultaneously execute a literature and actual research considering many manufacturing companies. In this paper we analyze various factors of logistics activities for environment conscious logistics system (ECLS) for economy base construction under resources circulation, and we especially analyze effects and causes of the influences of logistics performance by the operation characteristic of enterprises.

Since Korea is highly dependent on energy imports, it has been making efforts to save energy resources by enacting laws to promote resource saving and recycling. Recently, as a part of recycling of empty bottles, a bottle unattended collecting machine has been installed in the big shopping mall in the metropolitan area. However, there is no commercialization of the unattended collecting machine in Korea and the smart device application for providing information on empty bottle recycling is not yet provided. In this paper, we have designed and constructed a bottle recycling information management system to promote resource recycling. The manager has built a homepage that can manage the information of the empty bottle and the a bottle unattended collecting machine. Also, many people with smart devices can easily access bottle recycling information by using camera and barcode search and label search.

넥서스는 물, 에너지, 식량, 토지, 기후 및 환경 등의 부문 간 연관성과 상호의존성을 나타내며, 이러한 넥서스 개념은 최근에 학계와 정책결정자들에게 많은 관심을 받고 있다. 더 나아가 넥서스 관점의 도입으로 단일 부문별로 자원을 관리하는 기존의 정책 결정 체계의 한계를 극복하고, 관련 있는 부문 간의 시너지와 트레이드오프를 고려한 지속가능한 발전을 위한 의사 결정이 가능하게 되었다. 일반적으로 취수-도수-정수처리-송수-분배·급수-물이용-하수집수-하수처리-물재이용으로 구성되는 도시 물순환 시스템에서 공급과정에서 발생되는 물손실 관리를 위한 전략 및 프로그램은 물부문 만에서 평가를 통해 수립되고 있다. 본 연구에서는 시스템 다이나믹스(System Dynamics)를 적용하여 물, 에너지 및 환경 부문을 동시에 고려한 도시 물순환 시스템 모델을 개발하여, 넥서스 관점에서의 합리적인 도시 물손실 관리 방안을 도출하고자 하였다. 그리고 모델 내 부문 간 자원의 사용량 및 이동량의 정량화를 위해 물, 에너지, 환경 지표로 각각 물발자국(Water Footprint), 총 에너지 사용량(Total Energy Use) 및 탄소발자국(Carbon Footprint)이 적용되었다. 개발된 모델을 3개의 도시 에너지 인텐시티 현황(낮음, 보통, 높음)과 4개의 물손실 현황(낮은 물손실, 높은 물손실&낮은 명목손실비, 높은 물손실&보통 명목손실비, 높은 물손실&높은 명목손실비)을 고려한 12개의 시나리오에 적용하여 분석하였다. 그 결과 기존의 경제적인 측면 중심의 의사결정 과정에서는 명목손실이 물손실 관리 전략 수립 및 적용의 우선순위였으나, 넥서스 관점에서는 실손실 부분의 개선이 중요함을 알 수 있었다. 또한, 도시의 단위 물공급 에너지 인텐시티가 자원 사용 및 이동에 큰 영향을 미치는 것으로 분석되어서, 넥서스 관점의 의사결정시 사전적으로 분석해야 하는 중요 항목인 것으로 도출되었다. 이와 같은 범용적이고 포괄적인 도시 물순환 물-에너지-환경 넥서스 모델을 통해, 지속가능하고, 체계적이며, 구체적이고, 실현가능한 넥서스관점의 물손실 관리가 가능할 것으로 판단된다.

The purpose of this study is to analyze a case of social problem- solving R&D project. The case is about a food waste disposer system built in housing complex The characteristics revealed through the case study are as follows. It has been performed by the 'Connect and Solution Development (C&SD)' strategy that could shorten the whole innovation process. In order to increase the economic and social acceptability of the system, researchers formed a dense network with citizens, firms and local governments and tried to improve existing law to make new markets for the system. Instead of developing a new system in a top-down approach, they chose to use existing technologies and entities to address social problems quicker and easier.

The study aims that high quality recycled sand by wet manufacturing system can be used in practical way through basic material property. The basic material property test was done by 4 categories, dry manufacturing system (1) tandem and (2) parallel, wet manufacturing system (3) large capacity and (4) small capacity. RS-IV is the final production of (1) to (4) method, it is tested via KS F 2573 (recycled fine aggregate). RS-IV is satisfied with 4 items, those are absolute dry density, 0.08mm sieve throughput, clay lump amount, and organic impurity substance content. However, absorptivity item has problem in (1) and (2) method, (3) and (4) method are confirmed with norms 5% low. Also, the production quality of wet manufacturing system is better than dry manufacturing system in absolute dry density, absorptivity, 0.08mm sieve throughput, and clay lump amount.

일본의 농림수산성은 ${\ulcorner}$농업용 폐플라스틱${\lrcorner}$으로 호칭하고 있다. 연간배출량은 약 16 만톤에 이르고 있고, 이의 처리내용은 재생 38%, 매립 32%, 소각 11%, 등이다. 재생처리단계는 민간사업자가 기본으로, 처리내용은 일반적으로 PVC가 바닥재로써 쓰이고 PE가 서멀(연료)로써 쓰인다. 그러나 최근에 와서 비닐에 혼합되어 있는 이물질을 완전제거해 일정량의 버진과 배합함으로써 비닐을 반영구적으로 순환해 사용할 수 있는 기술이 개발되어 졌다. 이 싸이클시스템은 21 세기의 절약형사회에 적합한 것으로, 버진제품보다 저가에 공급되어 농업경영의 안정화에도 기여하고 있다. 한번 사용한 농업용 생산자재를 회수해 다시 생산자재로서 활용, 끝없이 순환한다는 개념이 뒷받침하는 이 기술은 향후 환경과 자원의 문제해결이라는 주목할 만한 가치가 있다.
