This study conducted a survey on the time serial change in the aging ratio and population structure in new towns and their housing complex of Korea and Japan, and revealed the differences in the factors that affect the aging ratio in new towns of Korea and Japan through a comparison of the housing provision of housing complex with a high aging ratio. Rapid aging is underway around the housing complexes that were developed in the beginning of Tama new town in Japan. Agingtends to increase in proportion to the opening time of the housing complex. Rental housing residents of early migration households showed rapid aging because they had generation separation early due to narrow housing. On the other hand, Bundang new town maintains a lower aging ratio and speed than Seoul and Seoul metropolitan area due to the constant influx of student population. On the other hand, aging is more likely to increase in large houses due to the depression of the real estate market.

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.

As the aging population of Korean agriculture and rural areas and the decline of the agricultural population are gradually deepening, the influx of population through returning to farming and rural areas is urgently needed. To this end, the most important problems to be solved were the lack of information that would help those who want to return to farming or rural areas when making decisions. Therefore, a survey was conducted for AHP analysis on related experts to find out the information (decision factors) required when selecting a return-to-farm or return-to-country migration area through this study. The AHP analysis showed that "Economic factors" were the most important among the three items in the primary class, while "Housing and land prices", "Metropolitan accessibility and traffic" and "Residential information" were the most important in the secondary class. The results of these studies are reflected in the information system to systematically support the decision-making of those who wish to return to farming or rural areas.It is hoped that it will be indirectly helpful and ultimately contribute to the revitalization and development of Korean agriculture and rural areas, which are aging.

This study seeks to clarify the influence of the stage migration which has proceeded through generations, on the population growth of local cities in the case of Jeollabuk-do. For this, setting to baby boomer as parents generation and echo boomer as their children, this study traces each generation's birth, distribution and the process of selective migration using aggregate level data. And the stage migration is analyzed by O-D, divided into three regions in each; Jeollabuk-do rural areas, Jeollabuk-do cities and other provinces. The major findings of this study are as follows. First, it was estimated that the number of the baby boomer births in Jeollabuk-do rural areas was seven times more numerous than in cities. Second, both rural and urban born baby boomers overwhelmingly moved into other provinces, especially Seoul metropolitan area and metropolis in their selective migration processes. However, there was also migration stream from rural areas to cities in Jeollabuk-do and the amount of this stream was approximately equal to the amount of outflux from cities in Jeollabuk-do to other provinces. Third, due to baby boomers' stage migration, from rural to urban, echo boomers were born in cities more than in rural areas. Fourth, urban born echo boomers still have moved into other provinces just like their parents generation in selective migration process. But comparing with baby boomer, the number of echo boomers influx from rural areas to cities has decreased. Consequentially the population of echo boomer in Jeollabuk-do cities also has decreased. Finally, the stage migration has been a basic cause of the social growth of urban population, and also influenced on the natural growth, closely connected with migrants' life course, such as marriage, childbirth and rearing. Therefore, this study concludes that the stage migration through generations is one of the crucial factor to understand the population growth in local cities.

The purposes of this study are to explain the background and significance of the 'Farmers' upstairs'(農民上樓) phenomenon which has been currently promoted as part of the "New Socialist Countryside Construction" in contemporary China, and its positive and negative aspects, and analyze the limitations of 'Farmers' upstairs'phenomenon. 'Farmers' upstairs'means the building of concentrated farmhouses by means of reconstruction of scattered farmhouses here and there, simultaneously by installing cultural, social welfare, and environmental facilities where rural farmer also could enjoy the convenience of urban living. It brings, however, the positive effects such as the improvement of living conditions of rural farmers, the simultaneously expanding of urban construction land and agricultural land, and the new influx of population from urban areas, whiles the negative effectives such as the forced demolition of farmhouses by governments or real estate developers with very lower compensation costs for the demolition of farmhouses, the gap from the standard of living, and above all, the inconvenience caused by the living in a multi-stories building in the rural villages. As a result, it is pointed out that the ongoing 'Farmers' upstairs', promoted as a kind of rural movement beyond a phenomenon, has similarities with the Rural Cooperative Movement(農村合作化運動) of Mao Zedong era(1953-61), namely the People's Commune Movement(人民公社運動) finally failed.

Parkinson's disease (PD) is a progressive neurodegenerative disorder affecting $1\%$ of the population above the age of 65 and is characterized by a selective loss of dopaminergic neurons in the substantia nigra pars compacta. Although the underlying cause of dopaminergic cell death or the mechanism by which these cells degenerate is still not clearly understood, oxidative stress, mitochondrial dysfunction, and protein misfolding are thought to play important roles in the dopaminergic degeneration in PD. Tetrahydrobiopterin (BH4) is synthesized exclusively in the monoaminergic, including dopaminergic, cells and serves as an endogenous and obligatory cofactor for syntheses of the potential oxidative stressors dopamine and nitric oxide. In addition to its contribution toward the syntheses of these two potentially toxic molecules, BH4 itself can directly generate oxidative stress. BH4 undergoes oxidation during the hydroxylation reaction as well as nonenzymatic autooxidation to produce hydrogen peroxide and superoxide radical. We have previously suggested BH4 as an endogenous molecule responsible for the dopaminergic neurodegeneration. BH4 exerts selective toxicity to dopamine-producing cells via generation of oxidative stress, mitochondrial dysfunction, and apoptosis. BH4 also induces morphological, biochemical, and behavioral characteristics associated with PD in vivo. BH4 as well as enzyme activity and gene expression of GTP cyclohydrolase I, the rate-limiting enzyme in BH4 synthesis pathway, are readily upregulated by cellular changes such as calcium influx and by various stimuli including stress situations. This points to the possibility that cellular availability of BH4 might be increased in aberrant conditions, leading to increased extracellular BH4 subsequent degeneration. The fact that BH4 is specifically and endogenously synthesized in dopaminergic cells, Is readily upregulated, and generates oxidative stress-related cell death provides physical relevance of this molecule as an attractive candidate with which to explain the mechanism of pathogenesis of PD.

The purpose of this study was to set and analyze the standard model for prioritizing and deciding to take part in housing environment improvement project in the perspective of the public sector. The results of this study were as follows. The location competitiveness, potential demand, marketability and competitive price, etc were selected by assessment indicators. And Various indicators, including of the size of the area, public transportation, accessibility, convenience of living and the influx of the population, were used by weights indexes. The profit of local residents and the public promoter, variability of earnings, sensitivity analysis and the ratio of money in reserve, etc were also established as detailed indexes for the profitability and business risk analysis. To analyze the cash flow of the project process and review the necessary capital in advance, the payback, total working expenses, gearing ratio and sensitivity of a risk, etc were also set as additional detailed indexes. Lastly, considering it is quasi-public projects, the measure to protect tenants, necessity need of redevelopment and local government's will were additionally used by indexes. And Points were distributed on the importance of each index and scored out of 100. It will allow for the public project promoter to decide rationally whether to come in on the project. The public project promoter like the Korea Land and Housing Corporation will be able to make use of various indexes are based on this study to make decision whether joining the housing environment improvement project in depressed region.

Cities developed by prosperity of industrial activities are inflated due to the rapid influx of the urban population. In the process, their structure was reorganized with overall urban redevelopment methods. As the a results from the propulsion of overall redevelopment plan, the city environment exposed uniform urban landscapes, absence of sense of place for permanent abodes and other urban problems. At the beginning of the 21st century, people with introspections on the problems focused their attention on making their places attractive using their place's unique identity so that people could feel like to stay there for a long time. They tried to regenerate buildings and cities while still maintaining spatial and historical context of their living environment. This study looks into the regeneration of Shikumen Linong House as a fine example of such a redevelopment in order to provide with a practical resource for urban redevelopment plans in Korea. The study in the first content examines the formation processes of the city of Shanghai as the gateway of the modern China. In the second, it looks into the formation processes and characteristics of Shikumen Linong House in the Xintiandi complex between 1920 and 1930's. In the end, it analyses spatial and formational characteristics and the applied dwelling regeneration method for the of Shikumen Linong House in the Xintiandi complex.

This study used the qualitative research for deeply interviewing Chinese-Koreans who live and work in Dearim-dong area, Yeongdeungpo-gu, Seoul, collectively. The variation of recognition to the local community at the migration early and the present and their response for overcoming their pending issues are studied through this, To understand the reality and conflict they encounter, the effort for overcoming the pending issues, the inner change of their own community, their fixed direction and so on becomes the core variables for integrating them to our society. They have formed the enormous cluster and have been already developed as the minority group. They are doing 'the struggle for recognition' for being recognized from the dominant group and trying to approach the politics for overcoming the inferiority of power. Accordingly, the intervention of social welfare to this minority group should be a more active working to protect the fragmentation of our society which can be resulted from the increasing influx of the foreigners and be also an approach to mutual enlightenment for making our society adapt to the phenomena of multi-nations and multi-cultures and for accepting them as the population.

Ulsan was selected as an industrial and industrial city, a leading city of Korean economic development in the 1960s, and it was rapidly changed social environment with the influx of many labor population. This change has had a great impact on the traditional customs of the region, and the traditional intangible culture has disappeared or disappeared, which requires urgent protection of intangible cultures compared to other regions. This study suggests the current situation to restore the agricultural music made up of the three-time customs recorded in the 1930s in Ulsan Dali area. The research method is literature research and field research. First, the literature analyzes the farming music in connection with the farming work performed in the Ulsan Dali area in 1936, and secondly, The field survey was based on the current situation of restoring farm music at the Nam-gu Cultural Center in Ulsan. The results of the research were observed in the Ulsan area, which has disappeared rapidly. In addition, it revealed the status of being handed down from 'Kim Dal-oh', a traditional farmer who worked at Ulsan Cultural Center, to 'Kim Se-ju', who is trying to restore the farm music.
