Due to long-term economic recession and change in population structure due to low birth rate and aging, the city is in new demand along with low growth era. There have been various social changes along with low growth. Especially, the city faces various problems such as decline of old downtown, collapse of root industry, severed community. Various types of urban problems are expected to last. In Korea, the number of vacant house is increasing centering around declining and older areas. As of 2015, there are 1.06 million vacant houses in Korea. Vacant house and its management plan became a significant issue in urban planning. Vacant house causes various external effect which lead to various social problems. For this reason, it justifies the intervention of public on vacant house problem. There have been various studies about the issue, but they lack in quality and quantity. Most of the studies only focus on utilization measure, and conduct fragmentary researches. To resist the generation of vacant house and efficiently manage them, studying original property of vacant house is of utmost importance. In this context, one must focus on cause and location property of vacant house. By apprehending the cause of vacant house and its location property, vacant house can be resisted and prevent spreding course. Thus, this study aims to resist the vacant house through understanding influential factors of vacant house and its location property, and suggest political suggestion to improve utility of vacant house management. To examine the cause of vacant house, it used spatial econometrics model. To confirm the spatial cluster, the study verified spatial auto -correlation using Moran's I index. Also, to examine the location property of vacant house in each region, the study applied Poisson regression. According to analysis result, the study confirmed that Korea lack in clear definition about vacant house or relevant fundamental statistics. This is a huge obstacle in conducting various researches to solve the problem. Vacant house has significant spatial aggregation and forms cluster. Also, such spatial cluster of vacant house tend to adhere while spreading to neighborhood at the same time. Nextly, according to spatial econometrics model to examine the influential factor, changes in population structure due to low birth, aging and changes in local economy structure was the major cause of vacant houses. Also, location of various convenience facilities and its accessibility had significant causal relationship with vacant houses. Finally, the location property of vacant house differed by local property and urban scale. In this context, it justifies a reason to examine the local and location property differently for future vacant house management policy. Based on the study results, the study's political suggestions are as follows. First, the public managing authorities of vacant house problem such as government or local government must focus on adhesion and spreading process of vacant house to resist generation of vacant house or efficient management of the problem. Also, the universal objectivity regarding definition of vacant house, terms and statistics must be secured. Next, as the study confirmed the locational property of vacant house is different, the managing body of vacant house project must be local government who can reflect local property of the vacant house rather than the central government. Finally, government and local government must conduct selective preferential policy targeting regions where the causes of vacant house are concentrated and spatial cluster of vacant house is strongly formed based on this study's result.

Recently, a variety of attempts are being made to strengthen regional competitiveness both in country and regional level. Furthermore, strengthening regional competitiveness is linked to strengthening national competitiveness, so it forms the ground for facilitating national growth. While diversified approaches are being discussed on these issues, recent trends seem like requiring more active ways to achieve regional competitiveness by exploiting regional circumstances and characteristics in conjunction with economy, industry and environment. Along with the changes appearing in domestic and international circumstances, the maximum use of regional resources including physical, human and environmental resources for achieving urban and regional competitiveness and the use of them as new driving force for growth are being increasingly required. Corresponding to these current situations, attention being paid to regional industry and economy gets higher. Regional industry that drives regional development is emerging as a major factor that causes rapid change in social and economic environment. Moreover, in respect of regional self-development and competitiveness achievement, regional specialization industry has close relation with a city’s economic self-sufficiency. The basic direction which regional specialization industry is heading in is categorized into a strengthening regional competitiveness and a promotion of the regional resources’ efficient use. The effect due to the policy of driving regional industry development through job creation in the region enables to induce the return of the effect to the region. Therefore, it is required to set the differentiated development strategy by means of systematic and objective analysis based on the characteristics of regional specialization industry and distinctive circumstances of the region. This study aimed at identifying major factors that influence the economic growth and the specialization industry of the region, and suggesting policy implications on ways to achieve continuous growth in regional specialization industry and regional economic growth by causal analysis of industrial specialization, industrial diversity and regional compounded growth rate based on the major influential factors identified in this study. This study tries to give opportunity to review potential impact influencing regions in advance in spite of its briefness. In new situations due to long-term change in industry that will occur in the future, this study also has significance in seeking fundamental policy implications to allow regions to effectively adapt to this new situations and to minimize the negative impact.

Traditionally, community space implies a small-scaled geographic area mainly hinged upon face-to-face contact. Nowadays, however, owing to the breakthrough of mobility equipped with the combination of high-speed internet and mobile phone, the social interactions occur in a wider area and the community extends beyond the conventional space, stressing the non-space world. Korea is no exception: the village is now at the center of community discussion, which has been strengthened by a series of "Maeul(Village)-Making-Movement" since the 1990s. Different from the past, however, as activities related with housing, labor, culture and leisure are separated each other, more people have to spend most of time outside the village. If community policies are confined to village, nowadays communities of people who do not spend their daily lives in the neighborhood are invisible and consequently it is not possible to support their communities. The key purposes of this study are to understand the reality of the community, drawing out reliable implications from the in-depth analyses of the intimate network of ordinary people. It examines 3,985 network data of 572 Cheongju people in Korea, applying the Social Network Analysis (SNA) methods. The followings are major findings. Firstly, neighborhood networks occupy only 6.1 percent, consisting of housewife and the aged. Secondly, 77.1% of the total networking occurs within Cheongju proper. The second position is given to connecting with Seoul Metropolitan Areas and nearby cities including Daejeon and Sejong. There exists a weak connection with other cities within Chungbuk Province. Thirdly, 85.12% of the total networking is geared towards a huge cluster, and main connectors are the unemployed, artists and activists of non-governmental organizations. These results imply that there are limitations in supporting the actual communities of the people within a village unit. With development of transportations and communication, accessibility is more important than propinquity to form a community, locally and regionally. In order to restore the community, various communal spaces which can be intertwined with places of labor, culture and leisure should be on the discuss table. Also, it is necessary to strengthen activities-based communities such as artistic activities and local movements. In this context, the unemployed group would be treated as precious social capital rather than insignificant social surplus.

취약성과 노출도에 근거한 침수위험도 평가 모델링

박기용 충북대학교 2018 국내박사

도시가 개발되고 확장되면서 다양한 환경문제를 겪고 있으며, 그 중 기후변화의 영향으로 도시에서의 재해가 점차 대형화, 다양화되고 있는 추세이다. 이러한 상황에서 도시방재의 중요성이 강조되고 있으며, 기후변화 관련 재해 중 가장 많은 비중을 차지하고 있는 침수와 관련하여 집중적으로 연구하였다. 인구와 주요시설들이 집중되어 있는 도시지역에 집중호우가 발생하였을 경우, 100m×100m 격자단위별로 침수위험에 대한 등급화를 통해 도시공간적으로 효율성을 높여 침수피해를 저감시키고 최소화하고자 한다. 도시 침수위험도를 평가하기 위해 취약성 분석과 노출도 분석을 하였다. 취약성 분석은 도시계획적 측면에서의 토지이용 및 건축물과 관련된 지표를 바탕으로 빅데이터를 구축하여 FUZZY 방법론을 활용하여 분석하였으며, 노출도 분석은 강우, 지형 등의 요소를 토대로 HEC-RAS와 FLUMEN 모형을 활용해 침수지도로 나타냈다. 이렇게 나온 토지이용 등급화 지도와 침수지도를 맵핑함으로써 도시침수 위험도를 Green, Yellow, Orange, Red Zone의 4개 등급으로 구분하여 평가를 하였다. 분석결과, 침수로부터 위험도가 높은 지역은 창원시의 주요기능이 집약되어 있는 중심상업지역을 중심으로 개발밀도가 높고 도시화가 많이 이루어진 지역, 그리고 과거 도심으로써 핵심적인 기능을 담당했던 구도심 지역들이 주를 이루는 것으로 분석되었다. 행정구역별로는 Red Zone의 분포율이 가장 높은 지역이 의창구(13.07%)로 분석되었으며, 그 뒤로 성산구(4.07%)>마산회원구(2.68%)>마산합포구(1.87%)>진해구(1.78%)의 순으로 나타났다. 이는 성산구와 의창구를 중심으로 신도시가 개발되어 이들 지역은 대체적으로 상업지역의 재산적 가치와 건축밀도가 높은 것에 기인하여 위험도가 높은 것으로 분석된 것으로 판단되는 바, 도시침수 위험도가 가장 낮은 녹지지역과 그 외의 용도지역을 적절하게 배분하여 토지이용계획을 수립하여야 하며, 위험도가 높은 지역에 대해서는 침수를 저감시킬 수 있는 방재시설, 공간시설 등이 적절히 배치하여 우선적으로 대책 마련을 해야 할 것이다. 또한, 본 연구의 객관화되고 과학적인 결과물인 도시침수 위험도 분석결과와 연계하여 침수 위험도가 가장 높은 Red Zone의 분포율이 높은 지역을 위험지역으로 설정하고 우선적으로 고려한다면 침수피해에 대한 효율적인 대처와 체계적인 관리가 가능해질 것으로 보인다. 본 연구는 향후 도시계획과 연계한 토지이용계획의 구체적인 계획 수립의 자료로 활용될 수 있을 뿐 아니라, 기후변화와 도시화라는 이슈와 함께 집중호우 발생 시 도시침수 피해를 최소화하기 위한 장기적인 대책으로 토지이용 부문이라는 새로운 대책을 제시했다는 점에서 큰 의의가 있다고 할 수 있다. As a city develops and expands, it is confronted with a variety of environmental problems, whilst the impact of climate change has gradually increased in scale and a series of urban disasters have become more diverse. Among various urban disasters, this study primarily focuses on the most frequent type, urban flooding. To deal with flooding issues in urban areas where population and major facilities are concentrated, different levels of flooding risk are classified on 100mx100m geographic grids to maximize spatial efficiency during the flooding events and to minimize the following flooding damage. In order to evaluate the risk of urban flooding, two analytical methods are adopted, that is, vulnerability and exposure tests. The former is based on land-use and building related indicators in terms of urban planning, and the collected data are analyzed, depending on fuzzy approaches. In contrast, the latter is based on the Hec-ras model using factors such as topology and precipitation volume. By mapping the classification of land-use and flooding, the risk of urban flooding is evaluated by the following(four grades) scales: green, yellowe, orange, and red zones. Major findings are: the areas with high flood risk are confined towards mainly central commercial areas where the main urban functions are concentrated and development density and urbanization are relatively high in addition to old urban centers. In case of Changwon, Euichang-gu (13.07%) has the highest portion of red zone, followed by Seongsan-gu (4.07%), Masan Hoewon-gu (2.68%), Masan Happo-gu (1.87%), and Jinhae-gu (1.78%), respectively. It evaluates that high property value of commercial areas and high building density within the new city centered on Euichang-gu and Seongsan-gu have increased the flood risk. Therefore, allocation of land use districts should be designed to reflect upon the different levels of flood risks for each use district to establish a more appropriate land-use plan, in addition to preparation of anti-disaster facilities to mitigate flood damages in high flood risk areas. Urban flood risk analysis for individual land use districts would facilitate urban planners and managers to prioritize the areas with high flood risk and to prepare responding preventive measures for the more efficient flood management. This study has a unique research value because not only could it be used as data designing future land-use and urban planning, but also it would contribute to proposing practical mitigation strategies against urban flooding under climate change.

The purpose This research tries to primarily find out whether the distance difference from Locally Unwanted Facilities(LUF) is influential on the land price. Using official land price data from January 2007 to January 2016, it examines land price trends in the neighboring areas of Cheongju Regional Waste Incineration Plant and Mongnyeon Crematorium Park located in Cheongju. The main target is given to spatial range within a radius of 3km and the double logarithm function of the Hedonic price model is applied. Major findings are: First of all, Hyuam-dong where Waste Incineration Plant is located experiences lower average land price. The same trend is repeated at Hyeonam-ri where Mongnyeon Crematorium Park is located. In specific, this research finds that areas within a 1km radius from Waste Incineration Plant are under heavier negative impact. In contrast, there exists linear proportional relationship between the average land price and the distance per se. Secondly, significant explanatory variables in this research are zoning(residential area), land use(shopping district), land category(fields and paddies, woods and fields), surface area, landform(gentle slow, flatland), park, distance to school, and road characteristics(boulevard, street, road). Among major variables, it finds that the distance from LUF is not so influential on the land price. Thirdly, it presents that significant explanatory variables for the area within a 1~2km radius are land category(sites, woods, and fields), distance to school and land use(shopping district). In case of 2~3km radius, land category(woods and fields), distance to park, land use(shopping district) and landform(flatland) variables are selected. Finally, this research expects that these findings would contribute to resolving public conflict or setting up compensation strategies against negative impact originating location of Locally Unwanted Facilities (LUF).

This study aims at exploring the fundamental business structure and networking relationship of local strategic industries based on the social network analysis methods. In addition, this study tries to present ideal directions of local strategic industries, identifying network status characteristics and spatial distribution of networks. Spatial scope of this study covers Chungcheongnam-do, and the analysis target focuses on its display business, one of its local strategic industries. Basic data supported by Chungnam Techno Park contain places of purchase and sale, transactions, and geographic locations of corporations linked to the display industry for the past 5 years. The basic analytical software is NetMiner 3.0. The research mainly deals with structural status and spatial aspects. To identify the basic structural characteristics of the network, the number of nodes and links, density, average connection, average distance, components, and concentration are examined. To confirm the status characteristics indicating the influence of corporations participating in the network, the degree centrality and betweenness centrality are explored. Furthermore, to identify the spatial characteristics of corporations participating in the network, analyse of block model position, E-I, SMI, density, and cohesive group are conducted. It has revealed that Chungcheongnam-do display industry has better business approachability than other industries, which can offer a huge benefit to business procedure and execution. In term of network structure of Chungcheongnam-do display industry, intensive distribution-type network has been primarily established. Although such intensive distribution-type network has the benefit of preventing functional problems even upon separation from the network, it can lead to excessive reliance on the key corporations of network. ALso, it can create high-handedness, such as intercepting corporate information revolving around networks and suspending exchanges. Therefore, reliance of the network structure on key corporations should be avoided, and supporting and managing small corporations participating in the overall network is necessary. Finally, Chungcheongnam-do display industry tends to overly rely on large corporations, given its industrial structure. Most of the powerful companies of display business are located in Seoul Metropolitan Region. Excessive reliance on large corporations can cause issues with the overall network when the business of large corporations becomes problematic. Such network structure with excessive reliance on metropolitan region can make it more overcrowded and cause the adverse effect of market monopolization; it is an issue that should not be overlooked. The findings of this study indicate that the status of Chungcheongnam-do in the display business network seems very weak, although it deals with local strategic industries. To overcome network problems, it is necessary to attract investment from various corporations. At the same time, a powerful management and supervisory agency should be newly established.
