This study was conducted to compare benthic macroinvertebrate communities of urban stream and nature stream in Daegu-si, Gyeongju-si, Gyeongsan-si, Andong-si, and Cheongsong-gun. The survey was carried out with 12 points in total six points for urban stream, six points for nature stream from Sept. 2011 to July 2012. In the urban stream were 33 species belonged to 24 families, 11 orders, 7 classes and 4 phyla while in the nature stream were 73 species belonged to 38 families, 12 orders, 5 classes and 4 phyla. In general, species diversity indices and species richness indices appeared low in urban stream but dominance indices was high. Functional feeding groups and Habitat Oriented Groups appeared comparatively simple in urban stream rather than nature stream. As a result of analysis of community stability, species included to area I and area III equally appeared in nature stream while species included to area I mostly appeared in urban stream. An analysis of the correlation between the population density and the number of species, the population number and biological indicators such as DI, H', RI, and ESB revealed that there was a significant correlativity with the diversity index and a very high correlativity with the number of species, abundance index and the ESB. On the other hand, the population number and the dominance index did not reveal any correlativity. For indicator species, Hydroptila KUa, Physa acuta appeared in urban stream while Paraleptophlebia chocolata, Epeorus pellucidus appeared in nature stream.

The purpose of this study was to predict the future urban activities effectively and rationally. For the purpose, a simulation model, based on SD, was built by integrating economic activities, land use and traffic of a city and by dividing Daegu Metropolitan City into seven districts and one county. To identify the effect of the development of a new city in the Dalsung County area, the future population and traffic volume of the city were predicted, using the model. The results are summarized as follows. The future population according to the development of a new city in the Dalsung County area was predicted, and the effects before and after the development twenty years later were compared. The future population of the Dalsung County was found to have slightly increased, whereas that of the adjoining Dalsuh Metropolitan District was found to has slightly decreased. For the other districts, there were no changes of the future population. It was found, therefore, that the development of a new city would have no effect on other districts. Then, the traffic volume according to the development of a new city in the Dalsung County area was also predicted. It was found that in the initial stage the traffic volume would increase with the increase in population of Dalsung County. It was predicted that particularly,. the traffic volume for the purpose of business would greatly increase. The traffic volume of Dalsuh Metropolitan District showed a slight decrease, whereas for the other districts, there were no changes of the traffic volume.

As the rural economy is worsening day by day due to rapidly declined population and increase of aging generation, the emptiness in the rural areas are becoming increasingly intensifying. In particular, urban runoff of young adults and middle-aged people and the decrease in birth rate have shrunk the rural population reaching to raise concerns on the stage of emptiness. On the other hand, people in the urban areas with rapid industrialization and overcrowding call for the variety of housing needs moving away from monolithic housing types. In order to solve problems of rural communities such as emptied out rural society as well as the problems of urban communities in overcrowdings, environment, and housing, it is required to develop an urban-countryside village complex pursuing advantages of the rural environment and convenience of urban living. Of this time, there needs a change in rural development policies which can make the urban residents migrate and settle in the rural areas as they are naturally embracing the rural life according to the social background and demand.

부산대도시의 공간구조와 그 문제들에 관심을 가진 많은 도시 학자들과 연구자들이 부산대도시 공간구조에 대한 관리의 필요성을 오랫동안 제기하였다. 그래서 본 연구의 목적은 1993년, 2001년의 기간 동안의 인구밀도, 고용밀도, 지가로 부산대도시의 공간구조의 동적인 변화를 알아보는 것이다. 본 연구의 중요한 결과들은 다음과 같다. 도심의 인구유출을 경험하는 동안, 주변부는 지속적으로 성장하였다. 중앙동은 인구 잠재성의 높은 접근성을 가졌다. 그러나 그 접근성은 1993년 이후 줄어들고 있다. 부전동은 2000년까지 인구가 증가하는 경향을 보이나 그 이후 년부터는 인구가 감소하였다. 그사이에 주변부는 높은 접근성으로 인구가 증가하였다. 그래서 부산의 공간구조가 다핵도시로 바뀌었다. 이 현상은 기존의 도심에서부터 자발적인 인구분산을 일으키게 되었다. 지가 변화에서는 부산 도시화의 분포패턴을 보여준다. 부산의 가장 높은 지가는 CBD에서 나타나며, 부산의 발전은 남북 띠를 따라 나아가면서, 서부산 지역에 영향을 주었다.

This study examines and analyzes residential environment and consciousness of downtown residents in Naju city and its results are as follows. Naju's population or urban population were decreased by half for 25 years, but area of residential regions was increased twice. It indicates that major parts of increased residence area are occupied by housing site development area. Uses of downtown buildings are for residential building mostly, but commercial building is less than 1/3 and story of buildings is mostly the first floor. So downtown area in Naju has residential function mostly and family composition is over sixties in more than half of population and regional aging is remarkable because household over majority of the population has no family under twenties. Downtown areas showed detached house and their own house in 2/3 of population and residents over majority of population have lived in current house over 20 years and had strong settlement. But housing site area is less than 40 pyeong at 3/2 of population and 2/3 of population have not parking lot. Most of population have dissatisfaction with their residential environment and for solving their dissatisfaction, improvement of poor residential environment, road extension and construction of parking lot are needed most. Most of residents consider that improvement of residential environment or economic level is normal or developed a little compared to five years ago, but when such a dissatisfaction is solved, they continue to live in their area.

Most studies on regional economic impact have utilized employment or employment income data. Recently, a few scholars have noticed the importance of nonemployment income sources in urban economies. Using decennial census data on Arizona towns from 1970 to 1990, this paper first examines the increasing importance of nonempolyment income sources in urban economies and the associations of nonemployment income sources with elderly population and metropolitan location. Then, this paper investigates the impact of nonemployment income on urban growth in the framework of economic base model. The regression results show that the impact of nonemployment income is significant in the increase of nonbasic income and becomes greater over time, and that the impact of transfer over time, and that the impact of transfer income on nonbasic income of transfer income on nonbasic income is stronger in smaller towns and the impact of investment income is stronger in larger towns.

Urban space expansion is an important symbol of the urbanization process and has always been an important topic in urban studies. In addition, for sustainable city management, it is important to identify factors that can influence, such as the driving force and direction of urban space expansion, from the stage of establishing an urban development plan. To understand these factors, by observing the expansion process of a specific city, it is possible to sufficiently observe how the urban spatial dimension changes. Through a series of processes, the spatial growth characteristics of the city are analyzed, and the influence and results of important factors are analyzed. For this purpose, this paper examines the changes in the city's outer boundary and land use structure through monitoring data on urban areas of 14 cities in Hunan Province, China from 2000 to 2016. Temporal and spatial regularity according to the urban space expansion of these cities were analyzed, and a preliminary assessment was made on whether the urban space expansion is coordinated with the urban population growth. The assessment result showed: (1) The urban space of most cities has been extended rapidly in 2000-2015 however, the rate and the intensity of urban space expanding has been declining. (2) The construction of the industrial park is the core driving force of the urban space expanding, and the change of the urban space structure is manifested as enclave city expansion because that the industrial park is usually far away from the city center. (3) The population agglomeration is another driving force of the urban space expanding. At this time, the urban space expanding is like boundary extension. (4) Except Changsha city, all of the cities has a high urbanization-area-growth elastic coefficient. It means that most of the cities should enhance the land use degree.
