급격한 기후변화와 도시화, 산업화로 인해 도시지역의 홍수피해가 증가하고 있다. 기후변화로 인한 재해 중 45%가 극한 강우 또는 홍수로 인한 재해로 확인되었으며, 급속도로 확장되고 있는 도시화 추세로 인해 도시지역의 홍수피해가 더욱 심화되고 있다(UNISDR, 2016). 기후변화 및 도시화로 인한 도시지역의 홍수피해가 증가하면서 시가지 건물 배치 및 도로망과 같은 복잡한 지역특성이 침수에 주는 영향을 분석할 필요성이 점차 증가하고 있다. 도시지역에서 홍수가 발생할 경우 복잡한 도로망은 배수로 역할을 하며 건물의 밀집도와 배치는 골목길 등에서 침수심을 증가시켜 안전한 구역이 좁아지는 효과를 발생시키고 있다. 본 연구에서는 우선 복잡한 시가지를 특성화하여 분석 할 수 있도록 이상화된 시가지 모형을 설계하고 제작한 후 유량에 따른 흐름 특성 변화를 분석하였으며, 기초 실험 결과를 바탕으로 강우강도에 따른 유황 변화와 연계할 예정이다. 기초 실험 수행을 위하여 먼저 건물 배치 밀집도를 고려하여 주거구역을 불록화하여 직선형의 이상적인 도시지역의 시가지 모형을 설계한 후 실험 모형을 제작하였다. 하천 범람으로 인한 침수발생을 재현하기 위해 상류 도로망에서 유량이 유입되도록 제작하였으며, 유입조건에 따라 변화하는 시가지 내부 침수 흐름은 LSPIV 기법을 이용하여 분석하였다. 유입조건에 따른 시가지 내 침수 특성을 분석한 결과 지형적 경사 특성에 의해 시가지 내부에서 흐름이 가속되며, 모형의 사거리 구간에서는 흐름 유입 방향에 대해 횡방향으로 흐름이 합류하는 경우에는 합류 흐름이 유속이 더 높은 것으로 분석되었다. 따라서 합류 이후 유속이 증가하면서 피해 발생 가능성이 높은 것으로 나타났다.

In 2005, the selection of 10 innovation cities was completed, and since 2013, public institutions began relocating to innovation cities. As a policy aimed at promoting balanced regional development, there were significant expectations from the regions. However, although the population moving to innovation cities has increased, it remains to be seen how much inflow is from the capital region and what spatial characteristics exist nationwide. Therefore, this study aims to analyze whether the innovation cities are fulfilling their roles by examining the patterns of inflow from the capital region and the spatial characteristics, and to reassess the policy direction for future innovation cities. We utilized the Microdata Integrated Service (MDIS) provided by Statistics Korea from 2013 to 2021. For the data collection reasons, we focused on analyzing the three cities. The results showed that in the initial stages of innovation city development, there was a significant influx of population from the capital region, leading to some effects on population dispersion and balanced regional development. However, over time, a phenomenon emerged where more people started to move back to the capital region, indicating a problematic trend. Furthermore, the Gyeongbuk Innovation City and Gwangju-Jeonnam Innovation City showed similarities in terms of reasons for migration, age of householder, and number of household members. However, the Gyeongnam Innovation City exhibited distinct characteristics compared to the other two cities. While the reasons for this phenomenon may be diverse, the current situation suggests that the goal of achieving "balanced national development" has reached its limits. Therefore, urgent measures need to be taken for improvement that take regional characteristics into account. Furthermore, in designing the second phase of the public institution relocation plan is required to avoid repeating the same issues and ensure a more thoughtful approach.

As the problem of lowering the efficiency of urban services in small and medium-sized cities in the non-metropolitan area intensifies, the necessity of developing a railway station area is being emphasized to form a compressed urban space through regional bases. Although major station areas in large cities are being developed in the form of complex, the analysis of the development location characteristics of the small and medium-sized city station areas is insufficient. The purpose of this study is to analyze the characteristics of development project conditions and potential demand in the high-speed rail station areas across the country, identify the differences in locational characteristics according to the type of city, such as 'metropolitan city', 'large city in non-metropolitan city', 'medium and small city in non-metropolitan city', and find out the appropriate development method. As a result of the analysis, it was analyzed that the 'metropolitan area metropolitan area' has high potential demand and poor business conditions. On the other hand, in the case of the non-metropolitan area, it was analyzed that the 'small and medium-sized city station area' has good business conditions and low potential demand characteristics, and the 'large city station area' has intermediate characteristics. This suggests the need for different development methods in the development of metropolitan and small and medium-sized city station areas. The analysis results of this study show that it is desirable to encourage private participation in large-scale metropolitan station areas, which require large-scale input, to maximize potential demand, and to encourage private participation through public-led projects based on favorable business conditions or development based on regional characteristics.

The purpose of this study is to suggest the design parameters, which are applied to the solid waste treatment and management systems in rural area. In order to drive out the parameters, the solid waste production and management systems in rural and urban areas had been surveyed and analyzed, respectively. The comparisons of the analyzed results are also introduced in the paper. The rural areas referred to the survey are grouped in accordance with the industrial activities in those areas. The conclusions of the study are as follows: 1) The solid waste volumes produced per day per capita in rural area are less than those of urban area. For example, the average volume produced in rural area in 1995 is 0.85kg, which is two thirds of those in Seoul area. 2) for the treatment, the country has depended mainly on landfill. On the other hand, the incineration treatment ratio has been in creasing in rural area. 3) The physical and chemical properties of the rural solid waste, according to the analysis, are similar to those of the urban areas, which means the living pattern in those two areas have a little difference.

Purpose: The purpose of the study is to analyze the relationship between travel behavior and urban spatial characteristics in a hierarchical manner. Method: This study analyzed the relationship between traffic patterns and urban spatial characteristics for 83 cities in Korea by using a hierarchical linear model. Results: It was found that the urban spatial characteristics influenced the choice of transportation mode and travel time with personal attributes. However, the degree of influence on the choice of the means and the time required is relatively low through the policy of changing the city attribute, so the policy effect of mobilizing the land use policy for the traffic is theoretically, but the scale is not bigger than expected. Conclusion: In high density or the bigger scale of the city, the mass transportation system is widely supplied and used, but it does not overcome the drawback that it takes more time than the autos.

The Korean peninsular is a typical mountainous terrain country which has 75% of mountains with having featuring of east-high west-low and north-high south-low type. Though the physiographic feature is not changed, the future operational environment has been frequently changed through artificial transformation by people living in the city. While Korea has been changed continuously since 2000, 90% of Korean territory has been urbanized and the majority of people live in the city. In particular, in the case of combat in urban area, there might be lots of limitations because of confusing with millions of people and complex buildings. The combat commanders should make an effort to overcome such difficulties through detailed IPB(Intelligence preparation in the battlefield) considering various situation before planning for major operations. They should change warfighting concept and paradigm. This paper finds the normal characteristics of urban operation and physical traits of the Korean peninsular. As the urbanization has been accelerating in Korea, practical implications about how to prepare the urban operation are discussed.

The purpose of this study is to examine the possibility of crime prevention in consideration of urban physical environment by analyzing the spatial distribution characteristics and pattern using actual crime occurrence data of the case city. The crime data was rebuilt by transforming them into geographic information system to analyze the spatial aspect of crime occurrence. The findings are as follows: a change from 2008 to 2011 is indicated with similar trend. But the local movements of crime hot spots are found. Moreover crimes were happening along the roads in linear pattern rather than inside of blocks in commercial area. This indicates the importance of environmental improvement of roads and open spaces. In addition it was found that the crime occurrence in a dangerous district can be reduced and prevented through the physical environment design and urban planning. The findings will contribute to promoting fundamental crime prevention as the physical environmental improvement in a city and to building a safe community as its result.
