유역의 수량, 수질, 수생태, 지하수, 하천환경, 기후변화, 오염원, 하천 친수공간, 농업경작지 등 수자원 관점의 물순환의 범위를 넘어서 환경, 기후변화 적응, 경제성, 사회문화 등 다양한 분야를 포함한 통합적인 유역의 물관리 이슈와 문제점을 해결할 필요가 있다. 물순환 관리의 개념은 국토개발과 도시화에 따라 파생된 물순환 왜곡 및 그에 따른 제반 물문제(홍수량 증가에 따른 침수피해, 직접 유출량 증가에 따른 가용 수자원의 감소 등)의 해결을 위한 물관리 행위 전체로 볼 수 있다. 물순환 관리의 범위는 홍수량 감소를 위한 홍수관리, 가용 수자원의 증대를 위한 물 확보 등 물관리 전반을 포함해야 한다. 기존의 물순환 사업은 비점오염 관리에 중점을 두고 LID를 활용한 빗물 침투율 증대와 빗물 재이용 등의 관련 정책을 추진하였으나 이는 물순환 체계 전반을 다루고 있지 못하고 수질 개선에그 효과가 집중되었다. 따라서, 수량·수질·수생태·재이용 등을 종합적으로 고려한 물순환 관리에 대한 연구가 필요하며, 이를 통하여 개별적이고 시설물 중심인 기존 대책의 한계를 극복하고 통합물관리 관점의 물순환 건전성을 기반으로 유역의 안심공간 조성방안을 수립할 필요가 있다. 본 연구에서는 물순환 전반을 연계한 통합적인 물관리를 통하여 물 안심공간을 조성하기 위한 토대를 제시하는 것을 목표로 하며, 통합물관리 관점의 물순환 관련 데이터 수집, 유역별 물순환 수준의 진단 및 평가를 통하여 시범사업 모델을 마련하고, 사업에 따른 효과분석을 기반으로 중장기 추진계획 수립을 통한 실행력을 확보하는 것을 목적으로 한다.

With the recent changes in society and the introduction of new technologies, the usage patterns of parks have become diverse, leading to increased complexity in park management. As a result, there is a growing demand for flexible and diverse park management that can adapt to these new requirements. However, there is inadequate discussion on these new demands and whether urban park management policies can respond. Therefore, empirical research on how park usage patterns are evolving is critical. To address this, blog data, in which individuals share their experiences, was used to examine the spatial consumption patterns through semantic network and topic analysis. This study also explored whether these spatial consumption patterns exhibit experiential consumption characteristics according to the experience economy theory. The results showed that consumption behaviors, such as renting picnic sets and having food and drinks delivered, were prominent and that emotional experiences were pursued. Furthermore, these findings were consistent with the experiential consumption characteristics of the experience economy theory. This suggests that park planning and maintenance methods need to become more flexible and diverse in response to the changing demands for park usage.

The spread and damage of COVID-19 are putting significant pressure on the world, including Korea. Most countries place restrictions on movement and gathering to minimize contact between citizens and these policies have brought new changes to social patterns. This study generated traffic volume data on the scale of a road network using taxi movement data collected in the early stages of the COVID-19 third pandemic to analyze the impact of COVID-19 on movement patterns. After that, correlation analysis was performed with the data of confirmed cases in Daegu Metropolitan City and Local Moran's I was applied to analyze the effect of spatial characteristics. As a result, in terms of the overall road network, the number of confirmed cases showed a negative correlation with taxi driving and at least -0.615. It was confirmed that citizens' movement anxiety was reflected as the number of confirmed cases increased. The commercial and industrial areas in the center of the city confirmed the cold spot with a negative correlation and low-low local Mona's I. However, the road network around medical institutions such as hospitals and spaces with spatial characteristics such as residential complexes was high-high. In the future, this analysis could be used for preventive measures for policymakers due to COVID-19.

Since disasters have been getting stronger and wider according to the influence of climate change, those impacts on social and national economy have been also getting more severe in various subjects. However, as direct property damage as well as casualties are only measured in case of disasters, monetary figures on its losses are likely to be underestimated, which are known as a major barrier to both compensation for loss and making a regional disaster management plan. Thus, the main purpose of this study is to develop statistics appropriate to the direct and indirect socioeconomic losses, which have continuously been overlooked. To achieve this purpose, this study defines the scope of direct and indirect socioeconomic losses, provides a framework for developing those measurements, and determines a preliminary statistics list. Selection criteria to set the final list are decided and are then applied to the list. The result of this study can be used as basic data for further studies to estimate and calculate its socioeconomic losses from storm and flood.

The study aims to prove the raison d'etre of public libraries in urban regeneration paradigm. Life SOC Plan is one of South Korea's urban regeneration policies. Public libraries are considered important in life SOC Plan because public libraries are "Social Anchors". Social Anchor is space-time-bounded place that accelerates diverse people's interactions. Social Anchor makes collective identity that supports production of social capital. Public libraries are institutions producing social capital but have weak collective identity because their missions(open, sharing, equality of information) don't allow boundaries and membership. The study conducted literature reviews and case studies to confirm how collective identity of public libraries strengthens. As a result, the study confirmed that renovating under-used space based on urban regeneration paradigm makes place identity of the under-used space to collective identity of public libraries. Thus, constructing public libraries by renovating under-used space is Social Anchor formation model based on urban regeneration paradigm.

In this study, the correlation between convergence factors including social, environmental, psychological and physical factors and the health-related quality of life was examined using a structural equation model to find a practical alternative for improving the quality of life in the elderly people living alone. This study targeted 13,771 seniors from single households aged 65 and over, who were subject to the community health survey in 2014. Social capitals, stress, subjective health conditions and EQ-5D of the subjects were analyzed using SPSS 23.0 and AMOS 23.0. The analysis findings are as follows. The results of the model fit was good value with CFI=.906, GFI=.955, RMSEA=.074. In conclusion, these results demonstrate that for maintaining health and improving the quality of life in the elderly people living alone, families and local communities need to increase social capitals by providing care service for the elderly people living alone and grounds that they can participate in.

The IPCC (Intergovernmental Panel on Climate Change) recommended the importance of preventive measures against extreme weather, and heat waves are one of the main themes for establishing preventive measures. In this study, we tried to analyze the heat vulnerable areas by considering not only spatial characteristics but also social characteristics. Energy consumption, popu lation density, normalized difference vegetation index, waterfront distance, solar radiation, and road distribution were examined as variables. Then, by selecting a suitable model, SLM (Spatial Lag Model), available variables were extracted. Then, based on the Fuzzy theory, the degree of vulnerability to heat waves was analyzed for each variable, and six variables were superimposed to finally derive the heat vulnerable area. The study site was selected as the Daegu area where the effects of the heat wave were high. In the case of vulnerable areas, it was confirmed that the existing urban areas are mainly distributed in Seogu, Namgu, and Dalseogu of Daegu, which are less affected by waterside and vegetation. It was confirmed that both spatial and social characteristics should be considered in policy support for reducing heat waves in Daegu.

This paper aims to understand the changing characteristics of the Kumi region as a locality in Korea through the regional geography of the world-system approach. To illustrate the changing regional characteristics, we analyzed the economic characteristics or position of the Kumi region within the world-economy and its spatial structure with three divisions of Korean capitalist periods: the Japanese colonial period ($1910{\sim}1945$), the social chaos period ($1945{\sim}1960$), and the economic development period ($1960{\sim}$present). In the Japanese colonial and social chaos periods, as Korean society was incorporated into the peripheral zone within the world-System (world-economy), Kumi also was made into a peripheral agricultural area. As a result, the Kumi region shaped the rural spatial structure without an urban center or regional dominant center. In the development period, influenced by the manufacturing-centered economic policy which boosted Korea as a semi-periphery within world-economy, Kumi also was developed into an industrial region(or semi-periphery) with the establishment of the Kumi electronic and textile industrial complex. This industrialization transformed the rural spatial structure of Kumi into a core (urban center)-periphery (rural area) structure. As we identified above, the regional geography of the world-system approach turned out to be a useful methodology to study a locality or internal region. Therefore we should make efforts to study such regions through the regional geography of the world-system approach.

The concept of 'spatial association' explains spatial distribution pattern of geographical phenomenon based on similarity with neighborhoods, as in the Tobler's Law of Geography: 'Everything is related to everything else, but near things are more related than distant things.' In this study, we develop a time-series exploratory analysis tool for discovering temporal patterns of spatial association by combining spatial statistics and geo-visualization, and thus present a possibility to support spatial decision-making process. As for the spatial proximity weight matrix indispensable to measuring global and local spatial association, we employ a variety of flexible weighting schemes using geometric characteristics of areal unit. In addition, we renovate the existing visualization methods for more effective understanding of the procedures and results of time-series analysis on spatial association: for instance, temporal parallel coordinate plot with box plot, animated map for spatial association, and 3D Moran scatterplot. The feasibility of our system is verified by time-series analysis experiments on the spatial association of land price fluctuation rate for all administrative units in Korea, $1995{\sim}2004$.

기후변화에 따른 빈번한 태풍과 집중호우로 인해 지속적으로 피해규모가 증가하고 있으며 점차 다양한 지역에서 피해가 나타나고 있다. 과거 태풍 루사나 매미의 경우 도시유역에서 주요 피해가 발생하여 대규모 피해를 야기하였으나 2006년 발생한 태풍 에위니아의 경우 집중호우로 인한 배수문제, 산사태로 인한 토석류 발생과 이에 따른 도로 및 하천 유입으로 피해가 나타났다. 이러한 피해는 남해안 및 영남지방, 강원 영서지방에서 주로 발생한 것으로 과거 피해 유형과 차이가 난다. 기존 하천 중심의 치수대책만으로는 다양한 지역특성을 고려한 치수계획을 종합적으로 수립할 수 있는 한계가 발생하며 이에 따라 국토해양부(2001)는 수자원 장기종합계획에서 하도와 유역 시스템을 함께 고려하는 유역종합치수정책을 제안하였다. 홍수피해잠재능은 수자원장기종합계획(2001)에서 처음 제시된 개념으로 면 개념을 도입하여 공간적 비교가 가능하고, 단위구역의 치수특성 및 사회경제적 가치를 평가할 수 있도록 개발된 지수(이승종, 2006)이며, 치수안전도 설정을 위한 가장 중요한 개념으로 활용되고 있다. 그러나 최근에 제시된 개념으로 아직 이론적 기반이 미흡하며 지속적인 연구를 통해 수정된 개념이 제시되고 있는 실정이다. 본 연구에서는 유역종합치수계획 등 국가 치수정책을 수립하기 위해 중요한 개념인 홍수피해잠재능과 치수안전도의 치수계획 활용 사례를 조사하여 지역특성별로 유역분할기법을 조사 정리하였으며 국외 사례를 분석하여 유역분할기법의 발전 방향을 제시함으로써 유역단위 맞춤형 치수계획 수립을 위한 기초 자료를 제공하고자 한다.
