  • The main objectives of this research are to analyse and evaluate the demolishing walls initiative in Daegu city as the collaborative urban environment improvement initiative in South Korea using the actor network theory concept. Local authorities are unable to effectively and efficiently improve urban environment because of their limited statutory and financial powers. This inability crucially led to the formation of the demolishing walls initiative in Daegu city with building a coalition of the local people, interest groups and public and non-governmental organisations in the operational processes in order to improve the physical and social urban environments. Furthermore, co-ordination between local authorities and landscape architecture specialists not only to change the way in which they tackle urban environmental problems but also to make the local people aware of their potential ability in positively improving the urban environment.

  • The purpose of this research is to suggest directions for urban planning and policies for the creation of a happy urban environment. To achieve this objective, this study extracted the urban environment characteristic elements that were expected to affect the levels of individual happiness and empirically analyzed the factors that affect the happiness levels of people. To determine the elements of the urban environment, this research analyzed the variables, urban environment characteristics, such as physical environment, natural environment, social environment, and individual characteristics. Regarding the physical environment of the city, a lower population density and a higher level of walking environment satisfaction showed a high level of individual happiness. In terms of the natural environment of the city, more spacious park areas and higher green area satisfaction showed a high level of individual happiness. Finally, regarding the social environment of the city, social trust was found to affect the happiness levels.

  • This research aimed to analize the cognitive intensity of valuation(C.I.V) on urban environment as a first stage of the works on evaluative urban image under the hypothesis that it could be interpreted with a correlation analysis between the C.I.V and attitude(Satisfaction of unsatisfaction Intensity) toward urban environment. As a method of a study, 118 cognitive elements were selected representing an urban environment, and each of elements was suggested to citizens of Kyungju with 7 point Likert Scale. The analysis of C.I.V was operated under the three criteria: The first, three of urban space scale(urban scale, neighborhood scale, and housing scale), the second, four elements of urban living environment(safety, amenity, healthfulness, and effectiveness), and the last, thirteen urban unit environment(housing, traffic, education, tourism, medical/health, culture, etc.). The results were as follows: C.I.V to each of 118 elements was cleary defined, showing the possibilities of being applied to a method for subjective, or cognitive evaluation on urban environment: It was revealed that citizens'C.I.V was rather higher in non-physical, qualitative elements than in physical and quantitative ones. This shows well the limitation of the objective method of evaluation of urban environment: The results of the others' studies on the image of Kyungju based on the cognitive approach, being focused on the analysis of the visual aspects of urban structure, cultural assets, historic site and tourism, were almost same as this study but it was quite different for this research to reveal well the citizens' cognition on their living environment of traffic, education, medical, etc..

  • Urban planning is the task to explore measures for bringing order to the change in urban space of future predicted in relation to the size and purpose of the land and a variety of facilities in cities in order to present the environment that can promote the qualitative improvement of activities of residents, ensure orderly urban space of future, and create appropriate urban environment which meets the desire of citizens by anticipating the urban development on the basis of overall activities such as politics, economics, culture, etc, so that the improvement in urban life can be accomplished ultimately. Therefore, this study attempted to examine current conditions information necessary for establishing policies pursuant to the national land development plan and regional development, as well as respond to the needs of urban residents who need the improvement of settlement environment including various amenities for the convenience of life, by shifting away form the macroscopic and one-size-fits top-down approach of development so far and aiming a balanced development of national land in quest for welfare society and by utilizing the urban index as the basic prior task necessary for seeking the shift ind the direction of policies and setting the direction for policies on the basis of the top-down development approach which suits the anticipation and hope of local residents as the subject of development, considering the growing interest in the shift in the policies for regional development in this era of localization. Techniques for urban planning need to be applied, such as the prior planning and the following development, along with the support at the policy level for achieving the improvement in the related sector, in order to induce continuos urban deelopment based on the establishment of healthy and sound settlement environment, and furthermore, the efforts must be drven forward to improve the urban settlement environment while the urban planning and policies are established.

  • Most imprinted genes are concerned with embryonic development, especially placental development. Here, we identified a placenta-specific imprinted gene Qpct. Our results show that Qpct is widely expressed during early embryonic development and can be detected in the telecephalon, midbrain, and rhombencephalon at E9.5-E11.5. Moreover, Qpct is strikingly expressed in the brain, lung and liver in E15.5. Expression signals for Qpct achieved a peak at E15.5 during placental development and were only detected in the labyrinth layer in E15.5 placenta. ChIP assay results suggest that the modification of histone H3K4me3 can result in maternal activating of Qpct.

  • This purpose of this work is to explore the characteristics of urban thermal environment distribution with the case of Daejeon. To do that, this work applied GIS Spatial Statistics to the LandSAT images gathered from 2000 to 2011. The urban thermal environment distribution at the time point of 2 showed high spatial autocorrelation. Therefore, it is judged that spatial autocorrelation is needed to increase the reliability and explanatory power of the characteristics of thermal environment distribution. In the case of the thermal in Daejeon, its positive clustering appeared high at the time point of 2, and its clustering in 2011 more gradually decreased than that in 2000 to 2011. In particular, given the decrease in the core H-H region, it was found that the thermal environment of Daejeon was greatly improved. However, since the rise in the region L-L means another changed like construction of a new city, it is judged that it is necessary to come up with a proper plan. It is considered that this analysis of the characteristics of urban thermal environment distribution in consideration of spatial autocorrelation L-L be useful for providing a fundamental material necessary for the policy and project of thermal environment improvement.

  • Now architecture has been become a significant element which is able to determine the competitiveness as a cultural product by going beyond the concept that architecture offer a space for just residence and office. From old times, planning and managing the urban space create living space to be more comfortable and efficient. Nevertheless, all of a public and private have resolved urban problems only to create economy growth by shortsighted approach. Therefore, a more macroscopic for composing an urban environment emerged the need for access in terms of the plan, to these aspects of the landscape and urban residential environment that can be applied to the United States's PUD techniques and focus on the development of urban space cases by applied PUD to improve a more rational and efficient urban space and to creation lively dwelling environment and the favorable landscapes forming want to try.

  • The purpose of this study is to identify the relationship between the physical environment and mental health of the adolescents in urban and rural areas. This study was performed using the questionnaire survey method. The research subjects were high school students in Seoul and Jeollabuk-do rural areas. The questionnaire inquired about the housing, neighborhood, and school environments, and these contents were depended on previous studies. The survey was conducted from August 27 to September 6, 2013, and 446 data were collected. They were analyzed with the SPSS 12.0 program. The main results are as follows. 1) The urban adolescents evaluated physical environment to be better than rural adolescents. Specifically, the urban adolescents evaluated 'facility/accommodation', 'security/health', 'amenity' of the housing environment, 'disorder', 'comfortability', 'nature awareness' of the neighborhood environment, and 'noise', 'overcrowding', and 'security' of the school environment to be higher. 2) The urban adolescents' self-esteem was significantly higher than rural ones. 3) The physical environment factors, which had effects on adolescents' mental health, are different depending on the areas, and so adolescents' physical environment would be designed by the local environment conditions.
