This study aims to analyze the features of adaptation governance of local governments by applying a multi-level governance framework, and to draw policy implications. We analyzed changes in governance of 17 metropolitan cities/provinces, and 33 municipalities in terms of horizontal and vertical cooperation in the process of developing 'The Climate Change Adaptation Action Plan' and its implementation stage. The result shows that the plan contributed to the higher level of vertical cooperation between the central and the local governments to a certain extent, however, during the implementation stage, the level of the partnership decreased due to the absence of governance mechanism. These trends were statistically significant at the level of municipalities. The role of Korea Adaptation Center for Climate Change (KACCC) was also diminished after establishing the plan. The horizontal partnership level among the relevant departments of the local governments showed no significant change as the level was low even in the planning stage. Though Public-Private Partnership (PPP) has increased a bit, it was statistically significant only in the municipalities. Moreover, there was no governance mechanism for PPP or it did not work properly. Based on the results above, it is recommended that the effectiveness of the plans should be increased and support for climate change partnerships or forums at a local level that promotes adaptive capacity is needed. The role of metropolitan cities and provinces should be strengthened through building a multi-level partnership structure. Governance institutionalizing for monitoring and evaluation is also needed.

This paper aims to analyze characteristic by the cities focused on the ratio of new apartment resale that is one of the apartment unit sale market, which has been increased recently. So, this study examined characteristics of population, apartment trade & sale, housing with 162 cities and counties and performed multiple regression analysis with dependent variable, ratio of new apartment resale. As a result. the factors affecting the ratio of new apartment resale are 7variables, apartment sales rate, transfer of ownership, apartment turnover rate, sale volume, regional apartment rate, population increasing rate, housing average apartment sale price rate. In terms of the increase in apartment sales prices, the rate of sales price increase was relatively low in areas where the transaction rate for apartment sales is high, and the number of apartment sales right transactions increased as the number of other ownership transfers rose. As a result, the data will be based on the improvement of the government's policies and systems to stimulate the transaction focused on the real estate agents in the apartment market.

In smart cities around the world, urban environments have become more convenient due to information and communication technology(ICT). However, extant studies reveal that the level of life satisfaction of citizens has not improved compared to that of the pre-smart city and citizens are skeptical about the role of the smart city. This is largely because local culture and needs were neglected during the planing and development of the smart city. The research was conducted on Cambodia as a pilot site and our findings indicate that middle age group's population is significantly small and the society is at risk of losing its culture. Therefore, this paper opens up various ways of embedding cultural programs using technology in order to pass down cultural heritage to young generation, provide an emotional attachment to the inhabitants and further build up a new phase of cultural legacy. This will engender cultural uniqueness to the city and intrigue tourists around the world resulting in the growth of the tourist industry. This research will contribute locally by providing a sense of community to the public and globally by suggesting applicable methodology to other cities that are under the similar context.

This study aims to examine the difference in the rurality of rural villages near a metropolitan city. It investigated the general status and economic activities of the two villages near Ulsan Metropolitan City to find out what the differences are and to diagnose the reasons for such differences and their impact on future changes in the villages. Through this survey analysis, it found that the two villages have been continuously experiencing a decrease in population over the last 10 years, despite being near large cities. In addition, it also identified the characteristics of the agricultural and livestock industries taking center stage in economic activities. In other words, although the cases are rural villages near a big city, it was shown that the village near a provincial city is basically based on agricultural characteristics. Regarding future prospects, on the one hand, in the case of Dagae-ri, the villagers expect that the current livestock industry-oriented activities may continue to develop. On the other hand, in the case of Shinhwa-ri, the residents think that the rural characteristics may be rapidly lost and urbanized. Based on these findings, this study suggests that rural policies for villages near large cities also need to be applied in a discriminatory manner, taking into account the basis on which economic activities in the villages are developed.

There are approximately 1.06 million vacant homes in Korea, accounting for 6% of all housing, and approximately 98 thousand vacant homes are in Gyeongsangnam-do, taking up 8.7% of the housing in the province. In particular, the number of abandoned house in Gyeongsangnam-do is rapidly increasing from 6.7% in 2010 to 8.7% in 2015. This study examined the current state of abandoned house in Gyeongsangnam-do according to the characteristics of cities and rural areas, causes for vacancies, and demand for use of such abandoned house. The study areas were selected based on case studies in Korea and overseas, and a survey was conducted among residents in the selected areas. The survey was on awareness of abandoned house in the neighborhood, causes for vacancies, awareness of owners, the influence of the abandoned house, plans to deal with abandoned house, and plans to utilize abandoned house. The results showed that most residents were aware of abandoned house, especially the ones in rural areas, who had detailed perceptions about abandoned house nearby such as when the homes became empty and whether there are owners of the homes. As for the influence of abandoned house on the surrounding environment, both rural areas and cities responded that abandoned house mostly spoil the beauty of the neighborhood, followed by psychological anxiety such as fear of crimes. Regarding plans to utilize abandoned house nearby, at least half of the residents wanted to use them as rental housing after repairing them. A survey on the actual condition must be conducted at the provincial level in order to establish an integrated system to manage abandoned house in Gyeongsangnam-do. Moreover, it is necessary to come up with application measures according to categories and standards to classify the state of abandoned house in order to use them as resources for community regeneration.

In this study, we measured the concentration of Particulate Matter($PM_{10}$), Formaldehyde(HCHO), and Total Bacteria Count (TBC) at two facilities: day care centers, and postnatal care centers located in the cities of Gyeonggi, Gangwon, Jeolla and Gyeongsang from January 1, 2012 to December 31, 2015. $PM_{10}$ concentration was similar to the day care centers and postnatal care centers. HCHO concentration was the highest in the postnatal care centers. TBC concentration was the highest in the day care centers. Comparing the different cities, $PM_{10}$ concentration was the highest in Gyeonggi, HCHO concentration was the highest in Gyeonggi, and TBC concentration was the highest in Gyeonggi. As a result of HCHO's risk assessment, it was found that adults exceeded the carcinogenicity tolerance of $10^{-6}$ specified by the US EPA. This study is expected to be helpful in preventing damage to health from the contaminated indoor air at sensitive facilities, and can be used as basic data for indoor air quality management.

Identification of factors influencing regional population is critical for establishing government's population policies as well as for improving residents' social, economic and cultural well-being in the region. In this study we analysed the data from 2019 Population Housing Survey in Korea to identify the factors affecting the population size in each of the three regions: Seoul, metropolitan cities, and provincial regions. We applied a Bayesian quantile regression to account for asymmetry and heteroscedasticity of data. The analysis results showed that the effects of factors vary greatly between the three regions of Seoul, metropolitan cities, and provincial regions as well as between sub regions within the same region. These results suggest that population-related variables have very heterogeneous characteristics from region to region and therefore it is important to establish customized population policies that suit regional characteristics rather than uniform population policies that apply to every region.
