The purpose of this study is to examine measures to improve government's supply oriented housing policy in population declining cities. For this purpose, system dynamics simulation method was used to build urban-housing model and different sets of housing policies were tested to see their impact on local housing problems. Simulation result shows that there is no best set of housing policies that can solve all housing problems in population declining cities. It also indicates that housing policy that solve one type of problems can worsen other type of problems. Housing policy that increases population size has negative effect of housing oversupply. It also increases proportion of old houses in population declining cities. However, housing policy that makes city younger with newer houses tends to increase housing shortage and housing price. So, policy choice needs to be made with clear understanding of trade off between different policies. The result also shows it is difficult to expect a full scale effect of housing policy on local housing problems unless it is executed with regional economic development policy because local housing problems are so closely related with local economic problem in population declining local cities.

It has been long time since the local small-and-medium cities had lost their vitality due to the progress of aging, economic decline in urban areas, the lack of new growth engines, and the declining population in korea. In addition, since the implementation of the local self-governing system, the creation of new urban areas and the transfer of the administrative institutions to the outskirts of a city have accelerated the decline of old downtown. Rather, local small-and-medium cities would have a problem to make urban regeneration impossible. Under the recognition of such problems, individual self-governing entities have come up with numerous policies and implemented various policies for the revitalization of local small-and-medium cities, but it is a condition that the effect of their efforts falls shorts of expectations, such as the space of the similar style, which has been widespread in developed countries, simple restoration, and a few structural changes. In this regard, the part to be realized anew is to enhance the attractiveness of small-and-medium cities. However, is not possible to raise the overall attractiveness in a short time in reality. To select local assets to be utilized in urban regeneration, it is judged that gathering opinions of local residents is more important than any other thing. Accordingly, this study intends to present positive outcome for the purpose of the revitalization of local small-and-medium cities by finding the factors which can remind us of the collective memory of Jinju city and selection the critical factors to determine a detailed project plan from the perspective of urban regeneration.

Recently, Korea has been experiencing a problem of population decline, therefore the transition to a compact spatial structure is being urged. However, what is required is not just physical compression, but a compact city that also considers connectivity, in view of the changes in today's demographic and industrial structure. From this point of view, this study measures the compressibility of domestic cities suffering from extinction risk due to low birth rates, aging population, and population decline, and examined the spatial structure characteristics. In addition to the compressibility evaluation index used in previous studies, the compressibility of six indicators (population, land use, service accessibility, transport accessibility, connectivity, and concentration) was compared and analyzed, and a comprehensive compression index was calculated. The analysis results, based on the comprehensive compression index, classified 2.3% cities in the first grade, 4.6% in the second grade, 16.09% in the third grade, 43.68% in the fourth grade, and 33.33% in the fifth grade areas. Currently, the urban characteristics affecting the compactness index differ from region to region. Therefore, it is necessary to establish measures and policies for extinction risk considering the influence of each region's compactness index. This study is meaningful in that connectivity was considered using spatial syntax, and the compactness of cities at risk of extinction was compared and analyzed quantitatively. It is expected that this study will be used as basic data to establish the direction and action strategy for extinction risk cities.

The growth of vacant housing has been problematic in both Korea and other countries as it causes various socio-economic problems and negatively affects residential environments. Despite the importance of effectively managing vacant housing, few studies have been undertaken regarding spatial patterns of vacant housing growth. This study aims to examine spatial dependence in vacant housing growth. We used 2005 and 2015 Population and Housing Census and employed spatial modeling. The empirical analysis shows that there is spatial dependence in vacant housing growth. Also, the spatial clusters of growing vacant housing are present in the non-capital region and nearby cities while the spatial clusters of declining vacant housing are present in the capital region. The policy implications of this study are as follows: First, local governments should make collaborate efforts with geographically proximate cities for more effective management of vacant housing. Second, given that vacant housing is more prevalent and growing in the non-capital region, it is necessary to employ differential policies to manage housing vacancy between the capital and non-capital regions.

The area to be surveyed is the three-seat of Myeon office in Hwasun-gun, Jeollanam-do, where population is declining. Satisfaction with the use of local residents of rural central areas providing life services in the back area was identified, focusing on sustainable development and the compact cities. Based on the results of the study, the recommendations are as follows. First, the local spaces to be surveyed need a shift to a walk-centered choice and social structure, not a must-oriented, activity-centric structure. This not only improves the neighborhood of rural areas, but also increases the frequency of pedestrian exchange and helps keep the community afloat. Second, it could enhance the convenience of residents by reviving stocks in existing commercial areas and integrating public services. Finally, it has the effect of taking care of the socially disadvantaged and immigrants in terms of space welfare, and securing jobs through locally customized community businesses.

Recently, people in cities of developed countries are exposed to unfortified damages of crime and disaster due to urbanization, industrialization and information-oriented era caused by congestion of population in terms of hardware and various social pathology phenomena and frequent and large scale of disaster caused by crime and disorder, which occur in the course of going through nuclear family, a gap between rich and poor and aging society in terms of software. In this regard, demand for security upon individual life and property has been increased but the police that are responsible for the public security does not effectively reduce damage in life and property because their activities are mainly oriented in coping with security accidents more than prevention. Shortage of manpower and budget, retarded equipment, and heavy overwork are the reasons. In order to confront with this kind of situation, we should utilize CCTV system with the purpose of declining possible chances of crime, not for eliminating cause of crime as crime prevention activities to predict danger in advance as a way of prevention and we may expect a role of damage prevention by installing CCTV in places where security accident may possibly happen. In conclusion, there are invasion of privacy, misuse of the system, insufficiency of overall monitoring office management, lack of citizens' understanding and economical allotment of the system installation costs in installation of CCTV system. However. it is necessary to install the CCTV system for effective prevention of crime and prevention activities of security accidents and accurate PR of purposes of installing CCTV to local residents, establishing relevant laws about system misuse, allotment of equipment costs and fees by R&D of the system machinery, cost reduction method of storage, management and replacement, saving costs from co-operative attitude of government, and local autonomous entities and local residents should be involved.

Lights from cities have been a grateful outcome of industrialization and a barometer of how developed the city is. However, indiscriminate exposure to artificial lights caused displeasure to people, ecological crisis to the nature, and overuse of energy. for example, excessive light is cause serious diseases such as sleep disorders, cancer in human, declining populations caused by reducing the ability to reproduce for animals and Plant yield is reduced. Therefore, each local governments have came up with ordinances in accordance with the law "Light Pollution Prevention Act". Accordingly, we've analyzed current Chungcheongbuk-do's current states investigation and reduction method proposed for the light pollution act.

Recently, there has been an increasing interest in the migration of young people to local areas. These young people are discovering and reinterpreting local resources to open local businesses while generating new value in local activities and businesses. This study was initiated with the recognition that fundamental solutions are needed for these young people to settle and sustain residence in the local area. Edward Relph stated that 'place' is a fundamental attribute that influences human existence in the world and is the source of stability and identity formation for individuals. This is deeply related to the psychology of young people who have migrated to local areas. These young people accept the unfamiliar 'space' as a 'place' to form stability and personal identity. Therefore, this study utilized PhotoVoice methodology to examine the process and key factors of place identity formation among migrant youths. As a result, the study identified factors that enable young people to settle in local areas and sustain residence while recognizing elements the local government should focus on to support and address the influx of young people. The results of this study can serve as a foundation for addressing the declining population in local areas through the formation of a relationship population and spur the inflow of young people to local cities in the future.

The important of Smart City has been increasing on the driving force of 4^th industrial revolution and method to solve urban problems. Korea government introduced and implemented ubiquitous City as an intrinsic Smart City brand from the early 21^th century. Diverse types of Smart City projects were announced as national strategy by the spatial characteristics. National Test-Beds in Sejong city and Busan(EDC: Eco Delta City) are urban planning to be future city models for new town development. In the old towns in cities, various type of Smart City projects are support by government by urban growth stage; frontiers, stable or declining urban realm. 「3^rd Comprehensive Plan for Smart City(2019 ~ 2023)」 in Korea plans an important role to build innovative ecosystem and reinforce global competiveness by spreading of Smart Cities. For the successful Smart City as open and inclusive space, it is need that this space should be made by the cooperation of citizens, private sectors and local and central government.

The purpose of this study is to analyze the influence of the selective migration of young age group and the stage migration which has proceeded through generations, on the transition of fertility and the population growth in the rural and urban in the case of Jeollabuk-do. For this, we use O-D matrix of 20-34 age group, the distribution of that group and women of child bearing age, and vital statistics in 1970-2010. The major findings of this study are as follows. First, the outflows from their birth place are common and dominant features of 20-34 age group in each time. Second, there is the stage migration which preceding generation moved from the rural areas to the cities in Jeollabuk-do and following generation has moved from the cities to Seoul metropolitan area. Third the selective outflow migration of young age group has leaded to reduction of the childbearing population, declining birthrate, aging and natural population decline. Due to the stage migration, these depopulation processes occurred in rural area in the past, and currently it expands to the cities with about 15 years time gap. In fact, there have been the natural population decrease which annual number of deaths exceed that of births from the late 1980s in the most rural areas and in the early 2000s, such a phenomenon has been confirmed also in urban areas. Therefore, this study concludes that the stage migration through generations is one of the crucial factor to the population growth in local cities and also brings out the step-wise population decrease in settlement hierarchies.
