In light of recent social concerns related to issues such as water supply pipe deterioration leading to problems like leaks and degraded water quality, the significance of maintenance efforts to enhance water source quality and ensure a stable water supply has grown substantially. In this study, scan statistic was applied to analyze water quality complaints and water leakage accidents from 2015 to 2021 to present a reasonable method to identify areas requiring improvement in water management. SaTScan, a spatio-temporal statistical analysis program, and ArcGIS were used for spatial information analysis, and clusters with high relative risk (RR) were determined using the maximum log-likelihood ratio, relative risk, and Monte Carlo hypothesis test for I city, the target area. Specifically, in the case of water quality complaints, the analysis results were compared by distinguishing cases occurring before and after the onset of "red water." The period between 2015 and 2019 revealed that preceding the occurrence of red water, the leak cluster at location L2 posed a significantly higher risk (RR: 2.45) than other regions. As for water quality complaints, cluster C2 exhibited a notably elevated RR (RR: 2.21) and appeared concentrated in areas D and S, respectively. On the other hand, post-red water incidents of water quality complaints were predominantly concentrated in area S. The analysis found that the locations of complaint clusters were similar to those of red water incidents. Of these, cluster C7 exhibited a substantial RR of 4.58, signifying more than a twofold increase compared to pre-incident levels. A kernel density map analysis was performed using GIS to identify priority areas for waterworks management based on the central location of clusters and complaint cluster RR data.

This study examines the correlation between livestock odor civil petitions and the establishment of malodor control areas in Jeju Special Self-Governing Province, focusing on swine farms where numerous civil petitions regarding malodors have been received. After the designation of the malodor control areas, high odor concentrations occurred in Aewoleup and Jocheon-eup, and the odor concentration decreased in other areas. The number of civil petitions shows a consistent annual trend, with increased petitions from March, peaking during summer (July and August), and decreasing from September into winter. In Jeju-si, there were many civil petitions in Hallim-eup and Aewol-eup where there were many malodor control areas. However, in Seogwipo-si, there were also many civil petitions in Pyoseonmyeon, where there is no malodor control area. Additionally, we compared the average multiple of compound malodors and the rate of exceeding the maximum allowable emission level for compound malodors with the number of livestock malodor civil petitions to assess the actual state of malodors. The results reveal a stronger correlation between the number of civil petitions and the rate of exceeding the compound malodors allowable emission level than the average multiple for compound malodors. These findings provide valuable insights into addressing livestock odor concerns and enhancing malodor control measures in Jeju Island.

The livestock industry continues to grow around the world, but livestock odor is becoming an environmental problem that is difficult to solve. In this review paper, the current status of the domestic livestock industry, livestock odor complaints, mediation cases involving environmental disputes related to livestock odor, livestock odor management policies and standards, livestock odor sources, major odor compounds, and emission characteristics are summarized. Domestic meat supply and meat consumption per capita are increasing, and livestock farms are becoming large-scale and intensive. Livestock odor complaints increased 4.5 times over the last five years (2014-2019), and its proportion to total odor complaints was 19%-30%. Livestock facilities larger than a certain size are classified as odor emission facilities and are managed based on the Odor Prevention Act. The information presented in this paper can be used to establish strategies to promote the sustainable development of the livestock industry while resolving air quality deterioration and public health problems caused by odor emissions from livestock farms.

Incheon is an area where complaints about odors occur frequently and there are many sources of odor emission. In this study, we used a real-time monitoring device to measure the odorous concentration near the areas where there are complaints about odors. The measurements were carried out for the three areas (G, C, S) that are located around emissions sources. G is situated in an industrial complex that has a reputation for being one of the most foul smelling regions of Incheon. A petroleum refining plant and storage facility are located around C. S is a residential area nearby an industrial site. The concentration of major designated odor substances in the G and S areas satisfied the site boundary emission standards. With regard to the characteristics of odor substances by region, although the C area region had the highest odor intensity among the three regions due to the odor intensity near the oil storage facility areas G and S were similar in terms of odor intensity. In the region of the G area, the odor intensity was slightly higher at the northern side of t he industrial complex. In terms of the odor intensity of the designated odor substances, trimethyl amine was the strongest, followed by hydrogen sulfide. The real time monitoring system was necessary to analyze the changing trends of odor substances and for the determination of major odor sources. This study was conducted to identify the material causes of odors in areas of Incheon where there are frequent complaints about major odors.

민원은 도시를 관리하는 데 있어 고려해야 할 요소 중 하나이다. 마찬가지로, 도시공원은 도시민들의 생활과 밀접한 존재로서 정책적으로도 중요한 위치에 있다. 도시공원에서 행정의 대응을 개선하기 위해서는 도시민들의 도시공원 민원을 파악하고 관리해야 한다. 본 연구에서는 충청남도 아산시의 도시공원에 대한 전자민원을 분석하여 인식과 문제점들을 도출하고 해결 및 관리방안을 제안하고자 한다. 또한, 전자민원에 대한 일련의 분석과정에 대해서도 논하고자 한다. 아산시의 도시공원 민원을 분석하기 위해 텍스트 마이닝과 소셜 네트워크 분석을 사용했으며, 키워드의 출현빈도, 네트워크, 클러스터를 활용하였다. 향후 본 연구에서 제시된 연구 방법을 통해 지역별 민원에 대해서 분석한다면 지자체의 민원 행정에 대한 대응을 할 수 있을 것이다. 또한 민원에 대한 우선순위 결정과 해결 방안을 제시할 수 있을 것으로 사료된다.

The number of complaints of odor in urban area has been increased due to mixed industrial areas of odor-related factories and municipal waste treatment odor-producing facilities located in adjacent residential regions. In this study, the characteristics of odor were reviewed according to two types of complaint from regions in Incheon area. In this study, the characteristics of odor were reviewed in two patterns of odor complaints in Incheon area such as the complaints are maintained high continuously and are increased in recent period. International city with largescale residential areas with the environmental facilities and redevelopment of residential regions with the adjacent industrial complexes and other odor emission sources were analyzed. Based on these characteristics, the odor management measures of major odor generating sources in order to improve urban environment were discussed with reducing odor complaints effectively.

This study was conducted to find an odor reducible solution in Hwayang agricultural industrial complex. Civilcomplaints have lasted because of odor caused by recycled plastic producers. In order to understand the emissioncharacteristic and concentration of key odor components, we investigated the complex odor and 17 odorcompounds at 3 sites of five chemical facilities from march to october 2013. The results of complex odor showed8~12 at a boundary of 5 facilities. The results of complex odor showed 6694, 3000, 1442 at an emission (stack)of 3 facilities, which exceeded the emission standard. The highest compound and its concentration of each sitewas different because each facility has different processes and use different raw materials. We suggested thesuitable prevention facility for each company to reduce odor. We analyzed the odor contribution with the emission(stack) point of S, I, B and the inside point of W, J. S plant was Acetaldehyde (45%), I plant was Trimethylamine(32%), B plant was Styrene (35%), W plant was Hydrogen sulfide (42%), J plant was Hydrogen sulfide(41%).An objective of study is odor management area and will apply odor strict emission standards. A suitable preventionfacility should be operated efficiently based on survey data to reduce odor.

The relation between civil appeals of odor in major regions of Incheon area and the operation of odor management area was examined for recent several years. From the studies the civil appeals of odors in the odor management area were closely related and estimated to decrease gradually with the tendency of civil appeals of odors neighboring and outside the odor controlled regions showed the tendency of increase in the Incheon area. To explain those phenomena detailed analysis was conducted with quality analysis of those area.

The tendency of regional civil appeals and characteristics were investigated in Incheon area and the consciousness of citizen related with effective odor was analyzed from questions in this study. The tendency of regional civil appeals were different and the consciousness of citizen with the conception and kind of odors were diverse with each regions. The improvement methods of odor management were suggested from those results.

The malodor control law enacted in 2005, regulated malodor substances ansmg from factory or service industry. In this work, an attempt is made to understand the actual conditions of malodor occurrence for types of industry and to settle trouble for a odor complaint. The odor concentration unit (o.u/㎥) of each major odor emitting industry was actualized by the indirect olfactory method including air dilution sensory test method in Korea. The industry that malodor complaint originate mainly were Chemical manufacturing industry, Waste disposal facilities and Livestock farming. As the results, Livestock farming were measured from 3 o.u/㎥ to 30 o.u/㎥ in the source boundary site, Waste disposal facilities were measured from 300 o.u/㎥ to 669 o.u/㎥ in the stack and Chemical manufacturing industry was analyzed from 300 o.u/㎥ to 1442 o.u/㎥ in the stack. Sampling of the source boundary site was demand the reform because malodor state at the field not expressed properly. In oder to solve such problem, propose total odor emission rate (T.O.E.R) introduction.

The law of facilities safety is maintained for the purpose of protecting the safety of the people. Recently, the law of facilities safety is revised to introduce an evaluation system based on performance. In this research, we classified the civil complaints that occur continuously in relation to the introduction of the performance evaluation system and through this we drew the improvements to establish the system.

The comparison of demand and supply is needed for efficient ecosystem services planning. However, the gap between them cannot be analyzed as existing studies mainly dealt with only the supply of ecosystem services. This study compares the demand and supply of ecosystem services in Shiheung using environmental complaints and urban planning by semantic network analysis. As a result, ‘air’ and ‘water’ quality are magnified in demand, ‘energy’ and ‘water’ are crucial in supply. This result presents that citizen ask for the improvement of air quality in regulation services, although local government has plans for energy support in provisioning services. Periodic ecosystem services demand and supply monitoring will be the base of effective ecosystem services planning, which reduce insufficiency and surplus.

Purpose - Civil affairs are increasing in various forms, but civil servants who are able to handle them want to reduce the complaints and provide keywords that will help in the future due to their lack of time. While various ideas are presented and implemented as policies in solving civil affairs, there are many cases that are not policies that people can sympathize with. Therefore, it is necessary to analyze the complaints accurately and to present correct solutions to the analyzed civil complaint data. Research design, data, and methodology - We analyzed the complaints data for the last three years and found out how to solve the problems of Yongin City and alleviate the burdens of civil servants. To do this, the Hadoop platform and Design Thinking process were reviewed, and proposed a new process to fuse it. The big data analysis stage focuses on civil complaints - Civil data extraction - Civil data analysis - Categorization of the year by keywords analyzing them and the needs of citizens were identified. In the forecast analysis for deriving insights, - The case of innovation case study - Idea derivation - Idea evaluation - Prototyping - Case analysis stage used. Results - Through this, a creative idea of providing free transportation cards to solve the major issues of construction, apartment, installation, and vehicle problems was discovered. There is a specific problem of how to provide these services to certain areas, but there is a pressing need for a policy that can contribute as much as it can to the citizens who are suffering from various problems at this moment. Conclusions - In the past, there were many cases in which free traffic cards were issued mainly to the elderly or disabled. In other countries, foreign residents of other area visit the areas for accommodation, and may give out free transportation cards as well. In this case, the local government will be able to set up a framework to present with a win-win scenario in various ways. It is necessary to reorganize the process in future studies so that the actual solution will be adopted, reduce civil complaints, help establish policies in the future, and be applied in other cities as well.

본 연구는 전국에서 사육되고 있는 돼지 중 전라북도 내에서만 12%(1,151,406 두수)에 달하는 돼지를 사육하고 있으며, 다량의 악취를 배출하고 있는 돼지 사육두수가 많아 지속적으로 주변지역에 악취 영향을 미치고 있다. 특히 돼지는 최소취기감지농도가 낮은 악취물질을 배출함으로써 사람이 느끼는 심리적인 영향이 크고, 대부분 악취대책은 우선순위에서 제외된다. 특히 익산농장, 금오농장, 신촌 농장은 대규모 축사시설로 악취발생의 주요 원인으로 주목되고 있다. 주요 축산시설 익산시 민원 중 가축 분뇨에 대한 민원이 18% 이였으며, 축사 민원이 16%, 분뇨냄새에 대한 민원이 23%로 총 민원의 50% 이상이 축사와 분뇨 냄새에 대한 민원 이였다. 민원은 여름철 6,7,8월 여름철 민원이 많이 차지하고 있었다. 완주군 민원조사에서는 전체 악취 중 축산에 관련된 민원은 33%이상를 차지하고 있었으며, 공업 악취와 같이 가장 많은 비중을 차지하고 있다. 악취 중 왕궁 축산단지 근처 둔산리 악취 민원이 25%, 김제 용지면 근처 혁신도시 민원이 8%로 나타났다. 축사시설 배출원별 복합악취 측정결과는 익산 소규모 2, 익산 중대규모 2, 김제 소규모1, 정읍 중대규모 1 시설이 기준치를 초과 하였다. 특히, 김제 소규모 1은 복합악취 희석배수가 100배로 기준치의 6배를 넘는 수치를 보여주었으며, 배출원별 지정악취 주요 측정결과는 전체 축사시설에서 암모니아, 황화수소, 메틸멀캅탄 모두 부지경계선 지정악취 배출허용 기준을 초과하지 않았다. 메틸멀캅탄의 경우는 모든 지역에서 불검출 되었으나, 규모별로 평가 시 김제시 소규모 축사시설에서 암모니아는 337.4 ppb, 황화수소는 3.7 ppb 로 가장 높은 농도를 보여주었다. 연구결과를 토대로, 주변지역에 미치는 악취 영향권 분석을 수행하여 효율적인 악취저감을 위한 시설관리방안과 악취저감 정책을 제안하여, 지자체에서 축산단지의 효율적인 악취 민원관리를 제시하고자 한다.

정부에서는 분리수거에 의한 폐기물 감량화를 유도하기 위하여 1995년부터 전국적으로 종량제를 실시하고 있으나, 수거 및 운반단계에서 발생되는 문제(폐기물 방치에 따른 악취 및 미관저해 등 환경위생적인 측면, 수거차량 이동에 따른 교통안전 등의 문제)를 크게 개선하지 못하고 있다. 이러한 문제를 해결하고자, 생활폐기물 수거운영방식으로 이미 유럽 및 일본 등에서 운영되고 있는 자동집하시스템이 도입되고 있다. 대전광역시는 서구 도안동에 신도시를 조성하면서 친환경 도시환경 조성과 쓰레기수거 경비 절감을 위해 총사업비 927억원을 투입해 자동집하시스템인 크린넷을 설치하여 운영하고 있으나, 제1집하장은 수변공원내에 주거지역과 근접하고 있어 집하장 주변에서 악취에 대한 민원이 많이 발생하고 있다. 제1집하장 주변 악취 민원해결을 위해서 기존의 악취방지시설을 보완하여 운영하고 있으나, 효과적인 대안이 수립되지 않은 실정이며, 현재 악취방지시설은 약액세정법으로 운영되고 있어 새로운 약품의 추가 주입과 기존 주입약품과의 주입량 비율을 조정함으로써 부지경계에서의 측정값은 배출허용기준 15이하는 충분히 만족하지만 큰 효과는 없어 이에 대한 민원을 해결하고자 한다. 악취는 감각공해로 사람마다 악취의 강도를 느끼는 정도가 다른 특징이 있어 민원소지가 많으므로 악취는 배출허용기준을 만족하더라도 복합악취희석배수 만큼 악취가 발생된다는 결과를 의미하므로 악취가 전혀 발생되지 않게 처리하는 방법은 기술적 한계와 더불어 과다한 소요비용이 발생될 수 있다. 따라서 악취를 현재보다 줄이기 위한 방법적용은 기술적 부분과 비용적 부분이 동시에 검토되어야 하며 다음과 같은 방안을 제시할 수 있다. 1) 기존에 설치되어 있는 악취방지시설의 운전조건 수정을 통해(일반 물세정이 아닌 약액세정을 실시, 일반 활성탄을 첨착활성탄으로 교체) 보다 높은 악취제거 효율을 기대하고, 2) 기존 방지시설 운전조건을 개선한 후에도 사업장 주변에서 악취민원이 발생한다면 최종배출가스를 하수 차집관로로 유입하여 처리하도록 하며, 3) 장기적인 방안으로 기존의 악취방지시설로 악취문제를 해결하기 어렵다면 신규 악취방지시설(촉매연소)을 설치할 수 있다.
