Background: The purpose of this study is to investigate the pro-con of re-implementation by administrative areas and the difference in perception of community water fluoridation in implemented and non-implemented areas after the community water fluoridation in Korea was suspended. Through this, we intend to provide basic data that can help find ways to increase the support and interest of local residents. Methods: The 601 questionnaires collected through the survey and statistical analysis was conducted using SPSS Statistics 28.0. Results: As a result of analyzing the perception of the community water fluoridation according to the understanding of fluorine, the proportion of people who were not recognized by both fluorine and community water fluoridation was the highest (p<0.05). As a result of the analysis of the pro-con of re-implementation of community water fluoridation, the approval was high. Among those who responded in favor, the place of re-implementation showed that 'implementation nationwide' was high. As for the reason for favor, it was found that it was possible to prevent dental caries disease. The reason for the objection was the lack of knowledge about fluoride. Conclusion: The results of the survey for the pro-con of the re-implementation of community water fluoridation showed a higher degree of 'agree' and showed that people in the area where community water fluoridation was not implemented showed higher interest in oral health prevention and management. Through this, not only oral education, but also correct information on the implementation method of community water fluoridation, the benefits of community water fluoridation, and the facts that were misunderstood in the past, as well as oral education, can be provided to raise interest in community water fluoridation. It is thought that the expected effect of the re-implementation of community water fluoridation can be obtained if such activities are carried out.

Representative meteorological data of the rural water district, which is the spatial unit of the study, was produced using the grid-based national standard RCP scenario rainfall data provided by the Korea Meteorological Administration. The retrospective reproducibility of the climate model scenario data was analyzed, and the change in climate characteristics in the water district unit for the future period was presented. Finally the data characteristics and differences of each meteorological element according to various spatial resolution conversion and post-processing methods were examined. As a main result, overall, the distribution of average precipitation and R95p of the grid data, has reasonable reproducibility compared to the ASOS observation, but the maximum daily rainfall tends to be distributed low nationwide. The number of rainfall days tends to be higher than the station-based observation, and this is because the grid data is generally calculated using the area average concept of representative rainfall data for each grid. In addition, in the case of coastal regions, there is a problem that administrative districts of islands and rural water districts do not match. and In the case of water districts that include mountainous areas, such as Jeju, there was a large difference in the results depending on whether or not high rainfall in the mountainous areas was reflected. The results of this study are expected to be used as foundation for selecting data processing methods when constructing future meteorological data for rural water districts for future agricutural water management plans and climate change vulnerability assessments.

Smart water cities (SWC) are urban municipalities that utilizes modern innovations in managing and preserving the urban water cycle in the city; with the purpose of securing sustainability and improving the quality of life of the urban population. Understanding the different urban water characteristics and management strategies of cities situate a baseline in the development of evaluation scheme in determining whether the city is smart and sustainable. This research herein aims to develop measurements and evaluation for SWC Key Performance Indicators (KPIs), and set up a unified global standard and certification scheme. The assessment for SWC is performed in technical, as well as governance and prospective aspects. KPI measurements under Technical Pillar assess the cities' use of technologies in providing sufficient water supply, monitoring water quality, strengthening disaster resilience, minimizing hazard vulnerability, and maintaining and protecting the urban water ecosystem. Governance and Prospective Pillar on the other hand, evaluates the social, economic and administrative systems set in place to manage the water resources, delivering water services to different levels of society. The performance assessment is composed of a variety of procedures performed in a quantitative and qualitative manner, such as computations through established equations, interviews with authorities in charge, field survey inspections, etc. The developed SWC KPI measurements are used to evaluate the urban water management practices for Busan Eco Delta city, a Semulmeori waterfront area in Gangseo district, Busan. The evaluation and scoring process was presented and established, serving as the basis for the application of the smart water city certification all over the world. The established guideline will be used to analyze future cities, providing integrated and comprehensive information on the status of their urban water cycle, gathering new techniques and proposing solutions for smarter measures.

공공도서관은 지역사회 이용자의 다양한 요구를 파악하여 이를 충족시키는 서비스를 기획하고 제공하여야 한다. 도서관 이용자에 대한 이해를 위해서는 도서관 서비스 영역에 대한 파악이 우선될 필요가 있다. 현행의 공공도서관 서비스 영역은 주로 도서관이 위치한 행정구역으로 설정되고 있어, 도서관에 대한 이용자의 실제 접근 패턴을 고려하지 못하는 한계가 있다. 본 연구에서는 도서관이 속한 지역의 교통적 및 지리적 특성과 이용자의 도서관 접근 패턴을 반영한 서비스 영역을 생성하고자 하였다. 구체적으로 7개 특별·광역시의 502개 도서관의 도로 네트워크 데이터를 활용하여 경사도가 반영된 이동 거리와 시간을 파악하였으며, 최단 경로 알고리즘을 적용하여 도보 또는 차량으로 30분 이내 범위의 서비스 영역을 생성하였다. 그 결과 지형적 요소에 따라 도서관별 서비스 영역 양상에 차이가 발생하는 것을 확인하였으며, 이는 직선거리 기반의 서비스 영역과 비교하여 도서관 접근에 대한 현실적 여건을 더욱 잘 반영하는 것으로 판단되었다. 이러한 서비스 영역 생성 방법은 도서관의 이용자의 수, 특성, 요구를 보다 정확하게 이해하는 데 기여할 수 있을 것이다.

The frequency and scale of domestic flood damage continues to increase, but the criteria for responding to flood damage have not been established. To this end, research is underway to estimate the amount of rainfall in each region so that it can be used to respond to flood damage. The limit rainfall is defined as the cumulative maximum rainfall for each duration that causes flooding, and this research purpose to improve the threshold rainfall by estimating the damage based on the damage history in units of 5 years and analyzing changes over time. The limit rainfall based on the damage history was estimated by using the NDMS past damage history of the Ministry of the Interior and Safety and the rainfall minutes data of AWS and ASOS. The period for estimating the limit rainfall is 2013 ~ 2017, 2015 ~ 2019, and the limit rainfall is estimated by analyzing the relationship between the flood damage history and the rainfall event in each period. Considering changes in watershed characteristics and disaster prevention performance, the data were compared using 5-year data. As a result of the analysis, the limit rainfall based on the damage history could be estimated for less than about 10.0% of the administrative dongs nationwide. As a result of comparing the limit rainfall by period, it was confirmed that the area where the limit rainfall has increased or decreased This was analyzed as a change due to rainfall events or urbanization, and it is judged that it will be possible to improve the risk criteria of flooding.

2005년 10월 러시아 정부는 한국 시안화나트륨 수입에 대해 세이프가드 조치를 검토하기 시작하였다. 한국측으로서는 양국간 통상마찰 전례가 별로 없었고 WTO 미가입국인 러시아와의 통상협상에서 선진국 등 WTO 가입국과는 이질적인 협상 환경에 놓이게 되었다. 러시아와의 협상에서도 목표의 설정, 협상력의 제고, 정보의 획득, 관계의 개선 등 일반적인 통상협상의 요소들이 적용될 수 있었지만 정보접근의 제약, 제도와 절차의 불확실성이라는 새로운 제약요인이 나타났다. 한국측은 이러한 제약요인을 극복하고 협상력을 제고하기 위하여 정부간 협상을 제의하였고 러시아 수요업계의 협조, WTO규정과 러시아 관련법규의 해석, 수집된 정보의 활용 등을 통해서 러시아측의 시안화나트륨 조사가 기각되는 결과를 유도하였다. 향후 WTO 미가입국과의 통상마찰에 대비하기 위하여 상시적인 정보 수집채널이 구축될 필요성이 있다. 본 연구가 러시아와 유사한 협상 환경을 가진 국가와의 통상협상에서 활용되기를 기대한다.

Background: Learning from incidents for accident prevention is a two-stage process, involving the investigation of past accidents to identify the causal factors, followed by the identification and implementation of remedial measures to address the identified causal factors. The focus of past research has been on the identification of causal factors, with limited focus on the identification and implementation of remedial measures. This research begins to contribute to this gap. The motivation for the research is twofold. First, previous analyses show the recurring nature of accidents within the Ghanaian mining industry, and the causal factors also remain the same. This raises questions on the nature and effectiveness of remedial measures identified to address the causes of past accidents. Secondly, without identifying and implementing remedial measures, the full benefits of accident investigations will not be achieved. Hence, this study aims to assess the nature of remedial measures proposed to address investigation causal factors. Method: The study adopted SMARTER from business studies with the addition of HMW (H - Hierarchical, M - Mapping, and W - Weighting of causal factors) to analyse the recommendations from 500 individual investigation reports across seven different mines in Ghana. Results: The individual and the work environment (79%) were mostly the focused during the search for causes, with limited focus on organisational factors (21%). Forty eight percentage of the recommendations were administrative, focussing on fixing the problem in the immediate affected area or department of the victim(s). Most recommendations (70.4%) were support activities that only enhance the effectiveness of control but do not prevent/mitigate the failure directly. Across all the mines, there was no focus on evaluating the performance of remedial measures after their implementation. Conclusion: Identifying sharp-end causes leads to proposing weak recommendations which fail to address latent organisational conditions. The study proposed a guide for effective planning and implementation of remedial actions.

Numerous studies have established a correlation between sociodemographic characteristics and water usage, identifying population as a primary independent variable in mid- to long-term demand forecasting. Recent dramatic sociodemographic changes, including urban concentration-rural depopulation, low birth rates-aging population, and the rise in single-person households, are expected to impact water demand and supply patterns. This underscores the necessity for operational and managerial changes in existing water supply systems. While sociodemographic characteristics are regularly surveyed, the conducted surveys use aggregate units that do not align with the actual system. Consequently, many water demand forecasts have been conducted at the administrative district level without adequately considering the water supply system. This study presents an upward water demand forecasting model that accurately reflects real water facilities and consumers. The model comprises three key steps. Firstly, Statistics Korea's SGIS (Statistical Geological Information System) data was reorganized at the DMA level. Secondly, DMAs were classified using the SOM (Self-Organizing Map) algorithm to consider differences in water facilities and consumer characteristics. Lastly, water demand forecasting employed the PCR (Principal Component Regression) method to address multicollinearity and overfitting issues. The performance evaluation of this model was conducted for DMAs classified as rural areas due to the insufficient number of DMAs. The estimation results indicate that the correlation coefficients exceeded 0.9, and the MAPE remained within approximately 10% for the test dataset. This method is expected to be useful for reorganization plans, such as the expansion and contraction of existing facilities.

본 연구는 "임상도 현행화 제작(DB구축 작업매뉴얼)" (이하 작업매뉴얼)의 제작과정과 방법을 검토하고, 1:5k 수치임상도(이하 임상도)에 평가항목을 적용하여 제작과정과 방법에 대한 문제점 도출 및 개선방안 제시를 목적으로 하였다. 임상도에 적용되는 평가항목은 구획과 속성에 관한 사항으로 구분하였으며, 행정구역별 임분구조 특성과 파편화 분석을 통하여 작업매뉴얼의 제작과정과 방법의 문제점을 도출하였다. 작업매뉴얼의 구획에 관한 사항은 '인위적변화지와 자연적변화지'의 항목에서 제작과정이 제안되어있고 전국을 5분할하여 자연적변화지는 5년 주기로 인위적 변화지는 매년 갱신하고 있기 때문에 지역 간 구축된 임상도 DB의 일관성을 알아보고자 파편화를 분석하였다. 전국의 산림 패치수(Number of Patches)는 증가하고, 평균패치크기(Mean of Patch Size)가 감소하여 파편화 정도와 형태의 복잡성이 증가하였으며, 17개 광역시 도 중 4개의 지역은 파편화 정도와 형태의 복잡성이 감소하여 지역 간의 편차가 발생하였다. 또한, '산림의 구분' 항목에서 최소구획면적은 0.1ha로 구분하고 있기 때문에 임상도에서 구획된 객체(폴리곤 단위) 면적을 산출하여 최소구회면적 기준을 검토한 결과 전체 객체 중 최소구획면적 기준 미만이 되는 객체의 비율은 약 26%나 차지하였다. 이에 따라 '인위적변화지와 자연적변화지'의 갱신 주기와 정의 확립이 필요하며, 최소구획면적 기준에 대한 구획 기준의 개선이 필요하다. 한편, 작업매뉴얼의 속성에 관한 사항은 '수종변화' 항목에서 지형지물체계를 52종으로 분류하고 있으며, 이 중 입목지는 43종으로 분류하고 있어, 임상도에서 구축된 수종정보를 추출하여 분포비율을 검토하였다. 입목지 수종 중 분포비율이 0.1% 미만인 수종은 23종으로 약 53%를 차지하고 있으며, 상위 3종은 소나무와 기타수종으로 구획되어 있다. 또한, 무립목지의 관목덤불은 지형지물체계에서 분류하고 있지만, '산림의 구분' 항목에서는 정의 및 판독기준이 마련되어 있지 않기 때문에 '수종변화'의 지형지물체계의 재정립과 관목덤불에 대한 정의 정립이 필요하다.
