After the unification of Three Kingdoms, Silla Dynasty had been on the prosperity with continuous population growth during approximately 120 years. However, Unified Silla Dynasty experienced 11 times of famine and bad year by frequent droughts during 50 years since the late 8th century, and these caused to political, economic and social changes. It is evident that Silla Dynasty slowly declined by the droughts and famines, although ancient records described as still on glory days. Since then, national power of Unified Silla Dynasty was abruptly weakened by migration of residents, and 9 times of rebellion or revolt occurred during 50 years in the late 9th century. As a result, political and social agitations reached the maximum. These led to the collapse of the Unified Silla Dynasty, and King Gyeongsoon handed over the dynasty to King Wanggeon, a founder of Goryeo Dynasty. These resulted from the 500-year-cycle droughts and human activities that seriously devastated the vegetations by using trees as an energy source for hundreds of thousands people during several centuries. The devastation of vegetation destroyed farm lands and led to large changes in river and groundwater systems, and eventually, increased damages by droughts.

Publicly funded project centered urban regeneration projects have limitations in the implementation to fit the urban regeneration plan system under the 'Special Act on Promotion of and Support for Urban Regeneration.' Since urban regeneration projects have been promoted with publicly funded project centered uniform plans and non-planned systems as such, many problems have arisen such as increases in the time to establish plans such as many strategic plans and activation plans and resultant increases in social costs. Therefore, in this study, with a view to finding methodologies for the establishment and flexibilization of urban regeneration plan systems, the actual state of operation of the urban regeneration plan system was analyzed to find problems and present improvement plans for reestablishment of the South Korean urban regeneration plan system.

This study aims to analyze an evolutionary path and the dynamics of the Seoul Digital Industrial Complex in Korea based on the analysis of cluster life cycles. From the mid 1960s to the late 1990s, the life cycles and their characteristics of the Seoul Digital Industrial Complex (Guro Industrial Park) are examined as emergence-growth-sustainment-decline focused on the number of firms and employees. After the late 1990s, the number of firms and employees increases rapidly and the active actors of the growth and restructuring are transformed to the technology-intensive SMEs and knowledge-based service firms. Knowledge industry centers (apartment-type factories) help evolve into the life cycle of transformation as knowledge-based clusters after the mid 2000s.

The decrease in the school-age population caused the closure of private universities, but the guidelines at closed private universities are ambiguous, causing confusion. Therefore, this study intends to suggest a plan to utilize the closed school university. The government aims to increase the possibility of selling closed schools by preventing alley slums through the recovery of alley commercial districts and local communities. The data were collected through a Google survey from September 30 to October 8, 2021 and an on-site interview conducted on October 2, 2021. A total of 84 nearby citizens of the closed school university were surveyed, and on-site interviews were conducted with a total of five people. The collected data suggested the direction of utilization plan for closed school building. This study will present a model for the use of closed school property in the future and contribute to the establishment of urban regeneration policies.

There is a movement to respond to the decline of the city through urban regeneration projects, and in particular, the importance of residents-led is increasing. In addition, the concept of resilience to increase the resilience of the city in response to an uncertain future is emerging around the world. This study aims to diagnose urban regeneration projects from a resilience perspective. The target site of the study was set as a selection area for general neighborhood urban regeneration projects in Seoul, and the factors affecting resilience in response to the recent coronavirus were analyzed. As a result of the analysis, it was found that among the contents of the urban regeneration project revitalization plan, the social regeneration content that can lead to residents had a positive effect on resilience. It is expected that the resilience of the city can be improved if the contents that can enhance the self-sustainability of the residents are included from the stage of the plan.

Recently, Interests in rehabilitation of the old town center has grown. Incheon city are propelling many renewal plans for the area, Rapid Urbanization and outskirt developments have expanded city space and city center has been weakened and declined. With responds to these phenomena, World's interests on creative city is increasing nowadays and projects of creating creative city from many countries are being launched. Korea is one of the countries who follows this trend and is also proceeding projects on creating creative city. However, identities of our nation and city which have rapidly grown only based on logics of economic growth are disappearing. Hence, this study intend to focus on the cities of creative which draw the participation of its citizens. Thus, this study examining basic theoretical background from literatures, theory, precedent studies related to citizen participation & creative city. Then, the study establish a framework of analysis by extracting principal factors to creative city construction methodology centered on citizen participation. Furthermore, this study suggests the creative city construction methodology of citizen participation centered on for old downtown through survey residents consciousness.

This paper examines the recent changes of urban center in metropolis in terms of land use. Jung-Gu, Daegu City is analyzed for a case study, and publicly notified individual land price data of 2000 and 2011 are used as analysis materials. The analyzing results show that a lot of residential land uses diminished in urban center, but residential function is still significant despite such decrease. Commercial land uses also decreased. Office land uses increased, but the increase is insignificant. On the contrary, unused or miscellaneously used land increased considerably. The phenomena implicate that land uses in the urban center are not positive under the influence of inner city decline. Overall, more land use changes occurred in the frame than in the core of urban center. That is, land uses in the core is more stable than them in the frame. However, decreasing commercial land uses in the core is noticeable, comparing to the frame. Mixed land uses for residence and commerce are most deconcentrated and office land uses most concentrated. Mean center point and standard deviation distance of land uses did not change significantly from 2000 to 2011, despite considerable change of land uses. The finding reveals that land use changes are widely occurring in urban center.

We established and monitored survey sites in seven regions of Mt. Jiri to investigate population decline and change of the Korean fir (Abies koreana) over a ten-year period from 2009 to 2018. With the exception of one site (Seseok), the six remaining ones all showed a four-layer stratification structure. The importance value of Korean firs in all of the survey areas decreased significantly by 28.5%, from 55.7% in 2009 to 39.8% in 2018. The average population of objects with a diameter at breast height (DBH) of 5cm or more in all survey sites was 711 objects/ha in 2018, and the cumulative death rate from 2009 to 2018 was 10.8%. Among the death types, DS (dead standing) was the most dominant, comprising 82.4% of the total survey area. However, in Banyabong 1, which had a high gradient of 35°, the death types other than DS accounted for 44.2%. We estimate that A. koreana can maintain a stable population as its distribution type for each diameter class in the Saeseokpyeongjeon site showed a reverse-J shape. The average annual ring growth in all survey sites was 1.09 mm/year, with the most abundant growth observed in the Seseokpyeongjeon site, which was formed mainly by a subtree layer. The growth ring survey showed the estimated average age of A. koreana population in the Byeoksoryeong and Banyabong 1 sites to be 102 and 91 years, respectively, a general downward trend of vitality since 2013.

Recently, the rapid increase in vacant houses in urban areas has caused various problems such as worsening urban landscape, causing safety accidents, crime accidents, and hygiene problems. According to the Statistics Korea Future Population Estimation results, the growth rate of Korean population and households is expected to continue to decrease, which is likely to lead to an increase in the occurrence of vacant houses. If the problem caused by the occurrence of vacant houses is neglected, it causes not only a physical decline such as a deterioration of the residential environment but also a social and economic decline. In order to solve this problem, it is necessary to grasp the spatial distribution characteristics of vacant houses at the local level considering the existence of regional characteristics and spatial influence. Therefore, in this study, in order to measure global spatial autocorrelation, the analysis was conducted centering on the old downtown area of Busan, where there are many vacant houses through Moran's I and Geographically Weighted Regression(GWR). In addition, the distribution of vacant houses in different spatial units in Eup_Myeon_Dong and Census was analyzed to evaluate the possibility of Modifiable Areal Unit Problem(MAUP), which differ in the results of spatial analysis as the spatial analysis units change. As a result of the analysis, the occurrence of vacant houses by Eup_Myeon_Dong in the old downtown area of Busan had spatial heterogeneity, and the spatial analysis results of vacant houses were different as the spatial analysis units were different. Accordingly, in order to understand the exact distribution characteristics of vacant house occurrence, spatial dimensions using the GWR model should be considered, and it is suggested that consideration of the MAUP is necessary.
