This review examined the current administrative policies and guidelines for management of reclaimed soils after remediation processes and proposed practical strategies to improve the potential value of the remediated soil as a resource. Three management practices are proposed to facilitate more efficient recycling of remediated soil; obligatory use, quality certification, and tracking of the remediated soils. If properly implemented in utilization of remediated soil, these strategies could contribute to enhancing public safety by assuring soil quality. Such administrative tools, for both suppliers and demanders, are expected to mitigate potential risks associated with the transactions of remediated soil. To enhance the quality assurance process, a soil quality certification combined with the soil health assessment index was proposed. The systematic integration of the suggested practices with soil health assessment can allow to produce optimal results, encompassing affordability, efficiency, and accessibility, which helps establishing more robust 'Remediated Soil Recycling Management System (RSRMS)'. Subsequent researches should be conducted to develop more effective policies that incorporate soil health assessment tools. The proposed management practices for remediated soil, coupled with soil health assessment, can be a pioneering effort to achieve such goals. By fostering an environmentally friendly policies, the sustainable utilization of remediated soil can be attained. Overall, the proposed strategies can provide a sound framework for responsible and sustainable soil management practices.

본 연구는 탄소 중립을 달성하기 위해서 공공시설의 이산화탄소포집기술을 상용화 및 보급할 필요성이 있으므로 공공환경에 적합한 시설물의 디자인 적용 가능성을 검토하는 것이 목적이다. 탄소포집 및 환경정화를 위한 공공시설물의 디자인 방향은 공기 중 탄소 포집 기술 활용, 탄소 포집 및 흡착 소재 활용, 탄소 저감 식재 활용으로 분류하여 수립하였다. 본 연구는 탄소 중립을 위해 공공공간에 기존의 공공시설물과 차별화된 디자인의 신개념 공공시설물 디자인을 개발하였다는 점에서 시사하는 바가 크다. 탄소 중립기술을 적용한 공공시설물은 시대에 부응하는 친환경 공공시설물로 공원, 도로 등 다양한 공간에 설치될 수 있고 시민들의 휴식 및 커뮤니티의 역할로 보급 및 활성화에 기여할 것으로 기대된다.

Objective: This study was carried out for the purpose of identifying major substances contributing to the production of odor and evaluating the characteristic of odors. Methods: Complex odor and 17 odorous compounds were measured at 18 waste transfer stations located in Seoul. Results: The dilution ratio value of complex odor ranged from 4 to 30 times in the boundary layer of 18 waste transfer stations. At 6 measurement points among the 18 waste transfer stations, the dilution ratio values exceeded standards (15 times). When the results were evaluated in terms of their contribution to the formation of malodor, the patterns indicated that the highest concentration values in the residential waste disposal process were of i-valeraldehyde and acetaldehyde, while butyraldehyde and acetaldehyde accounted for a large proportion of odorous compounds from the waste recycling process. Conclusions: It was found that butyraldehyde and acetaldehyde were the primary compounds released from the food waste disposal process. Overall, aldehyde compounds were the greatest contributor to detectable odor intensity emitted at the waste transfer stations.

This paper presents a smart firefighting appliances monitoring system based on big data analytics platform using GS1 for Smart City. Typical firefighting appliances are fire hydrant, fire extinguisher, fire alarm, sprinkler, fire engine, etc. for the fire of classes A/B/C/D/E. Among them, the dry chemical fire extinguisher have been widely supplied and 6 millions ones were replaced for the aging ones over 10 years in the past year. However, only 5% of them have been collected for recycling of chemical materials included the heavy metals of environment pollution. Therefore, we considered the trace of firefighting appliances from production to disposal for the public open service. In the paper, we suggest 1) a smart firefighting appliances system using GS1, 2) a big data analytics platform and 3) a public open service and visualization with the analyzed information, for fire extinguishers from production to disposal. It can give the information and the visualized diagrams with the analyzed data through the public open service and the free Apps.

Recycling of coal combustion by-product(Ash) are becoming more improtant in the utilization business as a result of the increased use of NOx reduction technologies at coal-fired power plants. current disposal methods of these by-products create not only a loss of profit for the power industry, but also environmental concerns that breed negative public opinion. Since inherent characteristics make these by-product suitable for building materials, several types of artificial aggregates and construction bricks are manufactured and tested to verify the engineering properties.

As part of efforts to internally strengthen the research ethics capacity of the Korean Academy of Health Policy and Management, we have compiled research ethics issues that are frequently encountered in public health researches. Firstly, when reusing research reports or dissertations as papers, efforts should be made to avoid unfair duplicate publication. Compliance with the institutional review board exemption process is required, and additional efforts should be devoted during the text recycling process to prevent self-plagiarism or unjust duplicate publication.

The techniques to recycle and reuse plastics attract public attention. These public attraction and needs result in improving the recycling technique. However, the identification technique for black plastic wastes still have big problem that the spectrum extracted from near infrared radiation spectroscopy is not clear and is contaminated by noise. To overcome this problem, we apply Raman spectroscopy to extract a clear spectrum of plastic material. In addition, to improve the classification ability of fuzzy Radial Basis Function Neural Networks, we apply supervised learning based clustering method instead of unsupervised clustering method. The conditional fuzzy C-Means clustering method, which is a kind of supervised learning based clustering algorithms, is used to determine the location of radial basis functions. The conditional fuzzy C-Means clustering analyzes the data distribution over input space under the supervision of auxiliary information. The auxiliary information is defined by using k Nearest Neighbor approach.

처리공정별 연계처리수질을 검토한 결과 생물학적처리만 거친 생물반응조 처리수의 경우 연계부하율이 $COD_{Mn}$의 경우 1.67%(설계수질 기준), 2.59%(운영수질 기준), T-P의 경우 3.69%(설계수질 기준), 7.67%(운영수질 기준)로 다소 높게 나타났으나 하수처리장 운영에 미치는 영향은 거의 없을 것으로 판단된다. 또한, 고도처리공정인 산화부상분리 처리수 및 생물여과 처리수의 경우 연계부하율은 1% 내외로 고도처리설비 설치 시 과대 설비설치의 우려가 있다. 따라서 S하수처리장의 경제성 및 안정적인 운영을 고려할 경우 생물학적처리인 생물반응조를 거친 처리수를 연계하는 것이 바람직할 것으로 판단된다.

The central government in Korea has pursued a policy to privatize municipal solid waste treatment facilities in order to enhance the effectiveness of public financial management in recent years. To understand the intentions of local governments on this policy, the survey with questionnaires on 37 out of 256 local governments was made in October, 2007. The results were analyzed and compared in 6 classified policy areas. The results showed that local government had enough financial status to operate the facilities with proper services and had the opinion with positive management in finance with increasing rate of prospective views. Among the facilities operated by local governments, the satisfaction levels for landfill(46.2%) and incineration(40.0%) were relatively higher. However those for recycling and food waste resource facilities were not satisfied with showing lower rate of satisfaction. The priority of privatization in consideration among them were following in order of food waste resource plants(76.2%), incinerators(63.6%), and recycling facilities(53.9%) and the most considerable reason to privatize them was due to resolve financial problems(59.7%). They thought and expected that the privatization would provide cost reduction effects in local governments and also be easier to achieve the environmental goals. To enhance such privatization, expanding more incentives by central government would be essential as shown in the investigation of this survey.

본 연구는 전국적으로 운영되고 있는 음식물류 폐기물 공공자원화 시설 중에서 초기에 제시된 운전조건과 맞지 않게 비정상적으로 운전되고 있는 DDM환경자원센터의 탈취시설을 대상으로 하여 실시하였다. DDM환경자원 센터의 비정상적인 탈취시설에 대한 쟁점사항은 퇴비화시설내부의 탈취와 실내공기질 문제 및 시설 전반적인 탈취문제이며 특히 축열식 연소장치(RTO)의 운전 중 정지되는 현상과 세정탑 내 살수 불량현상 등으로 나타났다. 이러한 비정상적인 운전시설을 정상적 운전시설로 전환하기 위한 개선방안 및 대안으로는 발효조 상부의 전면필터 제거와 분진제거용 스크레버, 기수분리기, 롤필터 등의 설치를 제안하고자 한다.
