최근 우리나라에서 발생한 홍수 중 많은 관심을 불러일으킨 2010년 광화문 일대와 2011년 강남역 일대 홍수의 주요 원인은 하천관리를 통하여 대응해온 지금까지의 홍수와는 달리 도시의 우수배제 기능이 높은 강도의 강우에 대응하지 못한 것으로 분석되고 있다. 도시내부에서 발생한 이 같은 홍수는 도시의 기능에 심각한 영향을 줄 수 있으며, 거주민의 안전과도 밀접하게 연관된다. 본 연구에서는 도시의 기능과 거주민의 안전을 우선적으로 고려한 홍수 취약성평가 인자를 선정하고자 한다. 기존의 여러 홍수취약성 연구들에서는 취약성을 평가함에 있어 피해금액을 기준으로 적용하는 경우가 많이 있다. 장기적인 홍수대응, 완화 정책의 구상에 있어 예상되는 피해금액은 중요한 지표라고 볼 수 있다. 그러나 이 방법으로는 도시에서 발생 가능한 피해를 모두 반영하는데 한계가 있다. 도로, 지하철, 철도 등의 교통수단이 침수되는 경우, 피해회복을 위한 비용뿐만 아니라, 도시기능에 심각한 영향을 주어 도시의 생산성, 안정성에 막대한 피해를 남길 수 있다. 따라서 피해금액의 규모에 대한 접근만으로는 도시에서 발생한 홍수에 의해 피해를 받는 취약요인을 적극적으로 반영할 수 없다. 본 연구에서는 도시홍수 피해양상과 이에 대한 대응 방법 등 홍수의 물리적 위험성 뿐 아니라 홍수와 연관된 사회적인 요인들을 반영한 취약성 평가인자를 구성하기위하여 인자간의 인과관계 등을 고려하여 인자의 범위를 규정하고 델파이 설문조사와 문헌 연구를 통하여 전문가 의견을 수집, 분석하였다. 홍수취약성에 영향을 주는 요인들을 크게 3가지 그룹으로 정리하여 도시구조물, 거주민, 위험요인으로 구분하고 각 항목별로 영향인자을 선정하였다. 결정된 인자는 2011년 홍수피해가 발생한 도림천 유역에 적용하여 홍수취약성 평가를 수행하고자 한다.

Post-Occupancy Evaluation (POE), which is one of the construction environment evaluation methods, is a series of processes that ask about the functional requirements and satisfaction of an object from a life cycle perspective such as design/construction/residence. However, there are no POE research activities targeting large-scale units. On the other hand, large-scale third-phase new towns are being developed. Therefore, this study conducted a post-residence evaluation (POE) research activity in a large-scale unit (Multifunctional Administrative City). The procedure of this study is to conduct a literature survey on the current status and implications of the multi-functional administrative city area, and based on the research data, derive the Happy City evaluation index for the major issues and special issues of the Happy City. Afterwards, 450 questionnaires were conducted for the residents of Happy City, and POE analysis was performed on the derived data for each module. And based on the analysis results, implications such as problems and improvement points for the current status of the Happy City were derived. This can be used as a basis for the expansion of a large-scale new city into a self-sufficient city, and it can be used as a basic data for the development and improvement of a happy city that meets social needs in the future.

A residential space where a person lives in may change following the flow of time and it has evolved in various shapes through the development process of a city. In particular, after the 1900s when the modern urban planning was first applied in full-scale, the urban environment and residential environment have formed cities through systematic planning. Under the assumption that the level of satisfactory life for urban residents residing in such an urban environment would be influenced mutually with the residential environment and urban environment to carry out this study, and as for the methodology of this study, the questionnaire was implemented with the subject of residents in Seoul City and analysis was implemented for regression analysis through SPSS 20.0 program. The results of the study are shown as follows. First, the relationship of the residential environment and urban environment is classified for convenience, safety and pleasance to have the important implication, and the level of satisfaction for the residential environment is analyzed to show implications with influence on the level of satisfaction for settlement consciousness. Second, the relationship of influence of residential environment on the settlement consciousness with the characteristics of urban environment is statistically noticeable and the stability and pleasance would have the statistically noticeable influence on satisfactory residential environment and the convenience would not render noticeable influence. And, third, under the characteristics of urban environment, convenience does not have direct influence on the settlement consciousness and it is confirmed to influence on the settlement consciousness indirectly only through the satisfaction of variation in the residential environment.

The harbor back area is not a planned space, but rather a space created by harbor space development. For this reason, the residential environment in the area behind the port has been very poor from the past to the present. Recently, the redevelopment has been increasing in accordance with the function of the port space. However, the development of the domestic port space is limited to the port space, and there is still little preparation for improvement of the residential environment in the port area. In this study, the degree of decline of the port area was diagnosed and analyzed for the purpose of deriving urban regeneration scenarios to improve the residential environment of port - backed areas. The urban regeneration factor to improve the livability of the port - backed area, which has been declining since then, was derived, and the scenarios in which each factor was applied were constructed.

The Korean society has been dramatically changed in its population, with rapidly increasing number of multicultural families through international marriages. The objective is to investigate the dietary patterns as an acculturation for multicultural families in urban area. The research target was 89 marriage immigrant females in Daejeon, in whom 50.6 % was in their twenties and 49.4 % was in their thirties to forties. 39.3% of the subjects was from China and 28.1 % from Vietnam, which showed similar pattern to the ratio of marriage immigrants' homeland in Korea. As age goes higher, cultural adaptation in Korea was the integration pattern. Marriage immigrant females from Vietnam showed the highest rates of marginalization pattern as cultural adaptation. Moreover, those with longer marriage duration and with children tend to show higher rates of integration pattern. 'Food attitude', 'food diversity', and 'balance life' as eating behaviors are related with acculturation. In conclusion, the multicultural families in urban area showed integration acculturation patterns, which could be influenced by their socioeconomic factors, such as residence period and Korean language ability and food diversity as dietary patterns factors. Further study with a quantitative analysis is needed in order to understand the effect of dietary patterns on acculturation in the multicultural families.

In the recent years, there has been attempts to try to understand the urban waterfront in diverse aspects. This article aims to understand basically the port-city's waterfront by the cultural interpretation of it in the basis of the concept of Water Culture. Water has the attribute that put down the border between inside and outside. This attribute of water leads to the attributes of Sea, such as dynamism, collectivity, and openness. The perimetric quality, openness, hybridity, and passage quality of the sea-port city's waterfront are resulted from these attributes of water and sea. These cultural attributes of urban waterfront exert a effect upon the residents' cultural identity of sea-port city. Thus the correlation between waterfront's attributes and the cultural identity should be reflected in the stage that its development is planned.

A model for radiological dose assessment in an urban environment, METRO-K has been developed. Characteristics of the model are as follows ; 1) mathematical structures are simple (i.e. simplified input parameters) and easy to understand due to get the results by analytical methods using experimental and empirical data, 2) complex urban environment can easily be made up using only 5 types of basic surfaces, 3) various remediation measures can be applied to different surfaces by evaluating the exposure doses contributing from each contamination surface. Exposure doses contributing from each contamination surface at a particular location of a receptor were evaluated using the data library of kerma values as a function of gamma energy and contamination surface. A kerma data library was prepared fur 7 representative types of Korean urban buildings by extending those data given for 4 representative types of European urban buildings. Initial input data are daily radionuclide concentration in air and precipitation, and fraction of chemical type. Final outputs are absorbed dose rate in air contributing from the basic surfaces as a function of time following a radionuclide deposition, and exposure dose rate contributing from various surfaces constituting the urban environment at a particular location of a receptor. As the result of a contaminative scenario for an apartment built-up area, exposure dose rates show a distinct difference for surrounding environment as well as locations of a receptor.

Urban parks are public spaces that provide various services for any urban resident to use and enjoy. Parks should be fairly distributed so that the urban parks can be equally used amongst different regions, generations and classes. Researches on spatial distribution of urban parks have been continuously conducted from the past based on the principles of fairness with variety, and it was evident that their techniques have become more elaborate and sophisticated. Yet, there have been limitations in the analysis of residents who are the main users of the urban parks. The research done so far was unable to apply the real number of the residents and it was carried out by only classifying and analyzing the population by the same scale(grid in the same sizes), postal(zip) code and administrative district. The actual population that resides within the usable range of urban parks was not used. This study analyzes and evaluates the spatial distribution that the residents can use on foot, by utilizing the service areas and the residents' registration data by addresses. In this study, to analyze the square measure of the service areas of neighborhood parks in Daegu Metropolitan City and the number of residents within and outside of the service area, network analysis techniques were employed and the residents' registration data were utilized. Major findings were that the Square measure of service areas of neighborhood parks turned out to be 31.23% of the square measure of the residential areas and also, that only 43.03% of the population of the Daegu Metropolitan area lives within the service areas of the neighborhood parks.

In this study, we collected 200,578,703 geo-tweets and removed the twitter bots. Using the concept of activity radius, Twitter users are classified. Users are also divided first into domestic and overseas, and again domestic ones are divided into locals and non-locals. Statistical characteristics of activity strength and active area of Twitter users are described according to activity radius and home region, and the geographical distribution is presented visually. Through a case study of Las Vegas, we have identified the difference in activity strength and active area by the user's home residence. We expect to derive theories about human mobility by analyzing various cities with the method proposed in this study.

Applying the construct of country image this study examined city image for Daegu in Korea. Study 1 measured the city image for Daegu and Seoul, identified the city image dimensions, and compared the images of the two cities. Study 2 confirmed the city image dimensions and examined the Daegu image by residency and demographic characteristics of respondents in Daegu and Seoul regions. The study extracted 4 dimensions of city image including economy, people, conservatism, and development capability. High conservatism and low economic prosper represented the image of Daegu while the opposite did of Seoul. Regardless of residency, single and Young respondents with high income and education had negative images for Daegu, and residents in Daegu rather than in Seoul had more negative images.
