As the domestic housing supply problem has been resolved, the apartment construction market has shifted to a consumer-oriented market that wants high quality, and in particular, expectations in the area of finishing quality have increased. Looking at the status of complaints regarding apartment housing defects supplied by Korea Land and Housing Corporation, tile-related complaints are the type occurring the most frequently. While the Ministry of Land, Infrastructure and Transport(MOLIT) is making an ongoing effort to reduce complaints related to defects, through approaches such as drafting amendments to 「Investigation of defects in apartment houses, calculation of repair costs, and standards for determining defects」, the provision of preventive measures has been insufficient. In addition, by reviewing studies, there has been insufficient research to construct a classification system after deriving the characteristics of each type using the qualitative knowledge of experts, various quantitative indicators, and suggesting measures for reduction according to the causes of each type. Therefore, this study will reflect qualitative indicators to use the AHP analysis that makes it easy to identify the relationship between defects by surveying construction experts. Then, by visualizing the weight of 'Possibility of recurrence after repair,' 'Degree of difficulty in repairing defects' and 'Fault frequency' using a radial graph, we will analyze the characteristics of each type of tile construction defect and establish measures for reduction according to the cause. This will improve the quality of the living environment and contribute to the establishment of a system for smooth defect management and reduction of defects in apartment tile construction.

Fourth Industrial Revolution and COVID-19 pandemic have boosted the use of Government 24 app for public service complaints in the era of non-face-to-face interactions. there has been a growing influx of complaints and improvement demands from users of public apps. Furthermore, systematic management of public apps is deemed necessary. The aim of this study is to analyze the grievances of Government 24 app users, understand the current dissatisfaction among citizens, and propose potential improvements. Data were collected from the Google Play Store from May 2, 2013, to June 30, 2023, comprising a total of 6,344 records. Among these, 1,199 records with a rating of 1 and at least one 'thumbs-up' were used for topic modeling analysis. The analysis revealed seven topics: 'Issues with certificate issuance,' 'Website functionality and UI problems,' 'User ID-related issues,' 'Update problems,' 'Government employee app management issues,' 'Budget wastage concerns ((It's not worth even a single star) or (It's a waste of taxpayers' money)),' and 'Password-related problems.' Furthermore, the overall trend of these topics showed an increase until 2021, a slight decrease in 2022, but a resurgence in 2023, underscoring the urgency of updates and management. We hope that the results of this study will contribute to the development and management of public apps that satisfy citizens in the future.

The purpose of this research is to develop system and to establish methodology for managing spatial Database in Land Management Information System(LMIS). Spatial Database which is used by a various public department such as parcel survey and registry, land use planning and Land value appraisal in local government, is composed of parcel map, topographic map and zoning map. Spatial data has been constructed and managed by various department and then hard to maintain accuracy and coinsistency. So, it is important to establish the basic data management concept that source data(ex : parcel map, topographic map, zoning map, etc.) should be managed by responsible department. at the same time, application data for bussiness (ex : individual parcel price map) must be recomposed from base map by it's own objects. This is, Spatial data management system (SDMS) should be designed, developed according to this concept for managing consistency among data, reducing construction and management cost of database. Our SDMS was developed based on Open LMIS middleware architecture using OpenGIS CORBA specification for standard interface, RUP(Rational Unified Process) for development methodology, UML(Unified Modeling Language) for system design and VisiBroker, C++, CAD system for system implementation.

The Ecosystem and Nature Map (ENM) is basic map for current status of natural resources. The map has been offered information to ecological conservation and restoration, as well as to land use planning and policy making. The map composed of 794 sheets in 1:25,000 scale classifies total areas into three grade zones (1st, 2nd and 3rd grade zones) and separately managed zone. In 2005, the first draft Ecosystem and Nature Map was prepared by the second National Ecosystem Survey. It was opened for the people to search and appeal. So 1,419 cases of public appeals on the first draft Ecosystem and Nature Map were submitted in 2005. After partial revision, the first Ecosystem and Nature Map was announced in 2007. The second draft Ecosystem and Nature Map was prepared by the third National Ecosystem Survey and opened to public in 2012. As a result, 1,263 cases of public appeals were submitted in 2012. Since the first announcement of the Ecosystem and Nature Map in April 2007, 182 cases of public appeals on the Map were submitted until December 2013. Among them, 159 cases were announced with revision. According to the first Ecosystem and Nature Map announced in 2007, graded areas covered 7.5% in the 1st grade zone, 39.2% in the 2nd grade zone and 44.7% in the 3rd grade zone of the national land area, respectively. In the second draft Ecosystem and Nature Map in 2012, areas of the 1st grade zone and the 2nd grade zone were 9.2% increased 1.7 percentage points and 45.5% increased 6.3 percentage points, and areas of the 3rd grade zone were 36.6% decreased 8.1 percentage points. Among areas of the 1st grade zone, Gangwondo occupies 54.3% in 2007 and 47.6% in 2012. Gangwondo consists of the highest percentage of the 1st grade zone and the smallest of the 3rd grade zone. Seoul has the highest percentage of the 3rd grade zone. There were the highest increase of the 1st grade zone in Gyeongsangbukdo and the highest decrease in Jeollabukdo and Seoul. Vegetation is the most important evaluation factor to determine the grade of the Ecosystem and Nature Map.

This study aims to analyze the current state of the operation of the information disclosure system in the judiciary of Korea to identify problems and suggest ways to provide more effective and substantive requests for information disclosure in the future. To this end, we reviewed the court's information disclosure claims process from 2007 to 2017 using the data published in the judicial yearbook and the data charged to the court information disclosure system of Korea. Results showed the different processes according to the person in charge, the high withdrawal rate, the complaint response rate, and the trend of the information nonexistence as the common problems. To solve these issues, we proposed to improve the various claims system, strengthen the education of the information disclosure claimant, publish the manual, and expand the provision and original text of information in advance.

4대강 유역에 설치되어 운영되고 있는 보의 개방을 통해 하천의 수질 개선 및 자연성 회복을 추진하고자 하는 정부정책에 따라 2017년부터 낙동강 유역 내 일부 보의 수문을 개방하고 모니터링을 진행 중에 있다. 그러나 보 건설 이후, 하천 주변의 농업형태 및 농업용수 취수 조건이 변화하였고, 보 개방에 따른 하천 주변 지역 지하수위 변화로 인한 농업용수 부족 현상이 발생하였다. 정부에서는 보 주변의 농업 현황 조사, 지하수 현황 조사 및 용수 공급 지원 등을 추진하고 있으나, 하천 주변의 농민들은 보 개방으로 인해 발생할 수 있는 농업용수부족 및 이에 따른 농업피해에 대한 우려를 나타내고 있다. 특히 지하수의 지열을 사용하여 겨울철 시설재배 농작물의 보온을 하는 '수막재배' 방법을 활용하는 농가의 경우 지하수위 저하에 따른 난방비 증가 및 농작물 냉해 피해가 발생함에 따라 보 개방에 대한 반대 입장을 고수하고 있다. 하천 주변에 분포하는 지하수는 하천의 영향을 받으며, 지표수와 지하수는 기저유출 등을 통해 상호영향을 받는 물 순환의 구성요소이므로, 보 개방으로 인한 하천수위 변화에 따른 주변지역 지하수위의 변화 패턴에 대한 체계적인 조사와 분석이 필수적이다. 따라서 본 연구에서는 낙동강 보 개방 모니터링을 위한 관측정 설치의 필요성을 조사/분석하고 최적의 관측지점에 설치하여 지속적으로 모니터링을 수행하고자 한다. 이를 통해 보 개방에 따른 주변지역 지하수 영향에 대한 조사 및 분석이 보 개방 모니터링 전후로 수행되어, 보 개방에 따른 지하수 환경 내 영향 분석, 농업형태에 따른 지하수 활용 영향 및 지하수 장애 발생 시 임시대책/항구대책 제시 등을 추진할 수 있어야 한다. 이에 따라 정부와 Kwater는 보 개방에 따른 현장조사 및 분석을 통한 지하수 관측정을 설치하고 지속적인 모니터링을 추진하고 있다. 2019년 현재, 낙동강 유역에는 총 194개소의 지하수 관측정이 있으며, 향후 수막재배를 많이 활용하고 있는 시설재배 농업단지 등을 보 개방에 따른 지하수 이용장애 민원 우려지역을 중심으로 지하수 관측정을 추가로 설치하여 보 개방에 따른 지하수 영향 분석 및 이에 대한 용수공급 대책 마련 등을 위한 기초자료 활용될 것으로 기대한다.

5 public complaint areas against odor in Changwon Industrial Complex were selected and investigated to clear up the cause of the complaint. 16 companies operated in public complaint areas were visited and had a grip of their situation about odor generation and treatment. Two samples at it's site boundary of each company were taken to measure complex odor unit. Complex odor unit at the site boundary of investigated companies in the public complaint areas, for the most part, exceeded standard(odor unit 20) in industrial area. It was due to that this area was not designated as odor control region and that there are also many problems in current laws of Odor Protection Act, Air Quality Act and regional legislation. Accordingly, It will be necessary to revise the related legislation, to organize governance, to financially support the improvement of environmental facilities and to enforce guidance and the regulation rigidly for the odor emission reduction in Changwon Industrial Complex.
