The remarkable growth of city population and rate of urbanization are increasing every year rapidly in Korea. On the other hand young people are decreasing and old people are increasing in rural areas. So in 2009, the five Rural New-Town Development Areas were selected by the Ministry for Food, Agriculture Forestry and Fisheries. To provide data necessary for housing types and floor planning and development suitable for rural new-town development to be implemented constantly in rural areas all over the country later, this study used a space syntax program to analyze housing types and space structures within houses in five new-town development areas. After analyzing 33 floor plans for the five areas, there were few houses with separation of communal (integration space) and personal living spaces (segregation space). In particular, 82% had personal living spaces requiring protection of privacy, such as bedrooms and the toilet, classified into communal living spaces. Residential houses for rural new-town development targeting the young population valuing personal life and privacy, which failed to reflect city people's life properly, were expected to decrease residential satisfaction after occupancy.

With the increase in industrialization and urbanization, growing demand has enhanced rate of new constructions and old demolitions. To avoid serious environmental impacts and hazards recycled concrete aggregates (RCA) is being adopted in all over the world. This paper investigates successive recycled coarse aggregates (SRCA) in which old concrete made with RCA in form of concrete cubes was used. The cubes were crushed to prepare new concrete using aggregates from crushing of old concrete, used as SRCA. The mechanical behavior of concrete was determined containing SRCA; the properties of SRCA were evaluated and then compared with natural aggregates (NA). Replacement of NA with SRCA in ratio upto 100% by weight was studied for workability, mechanical properties and microstructural analysis. It was observed that with the increase in replacement ratio workability and compressive strength decreased but in acceptable limits so SRCA can be used in low strength concretes rather than high strength concrete structures.

Urbanization has been causing such new pollutants as micro-plastic, thus the environmental impact of new pollutants on ecosystem is rapidly increasing. When it comes to micro-plastic, a representative artificial trace pollutant, its risk has been increased at a much faster rate, however the depth study associated with stormwater sediment and wetland was relatively rare. In this research, soil samples from storm water sediment were analyzed for distribution characteristics of micro-plastics in the J wetland (registered as Ramsar wetland, May 2021 and a representative environmental site in South Korea). Analyzed soil samples found approximately 201 ± 93 particle/kg (based on unit weight, Total micro plastic particles / Total Sample weight) micro-plastics in the samples. When considering the total quantitative numbers in stormwater sediment in the entire area of the J wetland, over 15,000 micro-plastics were estimated to be contaminating such area. In addition, in terms of qualitative numbers, micro-plastics were contaminating the J wetland with 94.7 % ratio of styrofoam type (43.9%) and polyethylene type (50.8%). These research results can be used as base data sets for controlling micro-plastics in the J wetland.

This study explores the typology of the urban detached houses in the new housing quarters that were created in the process of Seoul's urbanization in the aftermath of the Korean War. It analyzes and compares the urban tissue and space allocation set when the new urban residential areas were organized according to different methods of production. Based on the comparative analysis of housing built in the same time of 1960s, this study aims to deduce why a specific urban detached housing type was selected as an influential housing prototype and how this spread in later generations. Case study sites selected for this study include: the new Urban Hanok towns of Yongdu-dong, filled with mass Urban Hanoks built by housing developers; the single-family detached housing district of Myunmok-dong, filled with individual dwellings built by private builders; and the housing complex of detached houses in Suyu-dong, developed by government-sponsorship during the early 1960s. Each case examines the following: first, the difference in housing typology allocation according to urban tissue; second, the difference in spatial composition and arrangement within plots. As a result, it was found that differences in typology occur depending on which of the social, cultural, economic and technical factors was preferentially considered in forming urban tissue and allocating buildings in each residential area.

The agricultural population, the farming, the agriculture of our country has been decreased more rapidly than those of other countries. Also, the changing speed of the rural village in Korea has shown a similar trend. By considering the urbanization process and migration state caused by the economic growth and the increasing level of relative poverty in comparison with the urban area, it has been necessary to go through the impoverishment and slum-orientation of the rural area. In our country, the rural village became old age. So, the collapse is predicted to a population shortage if such trend is continued in the village society. according to investigate, Many urban peoples have opinion that migrates to a farm village. but those not migrate to rural community. The mainly reason is low life environment. therefore it is need the plan that the urban people migrates to a rural village, and must have the plan to be engaged in the agriculture. lt was the rural-fishing New Town development project that started in 2009 for 30~40 years's urban people. This study is about characteristic and improvement of Rural-Fishing New Town development project.

At the present stage of the world economic development, a new economic system is being formed, in which non-economic values, in particular environmental and social parameters, have become widespread. A new vision of economic activity is being formed, which acquires the qualities of Smart-economy. The purpose of this paper is reveal the features of managing the development of smart cities as specific entities of the Smart-economy. New functions of economic entities are formed within the framework of the Smart-economy concept, while their role and weight in the localities' activity or formation have changed. Determining that the key trends in the Smart-economy development are such as digitalization, greening, socialization, institutionalization, and urbanization, this is necessary to note that all these trends are most active in the formation of urban ecosystems. These trends are determined by the general population growth and the urban population growth, which requires considerable attention to planning each city's development itself. Such planning could ensure the comfort of living for all its inhabitants, quality, safe, and modern life. The Smart-city's key elements and the intellectualized approach implementation planes to the decision of these or those tasks are definedIt is determined that a new ecosystem of governance is being formed.

이 글의 목적은 최근 우리나라의 대도시에서 나타나고 있는 변화 경향들을 이론적으로 해명하려는 작업의 일환으로서, 1980년대 이후 서구의 지리학계에서 진행되고 있는 대도시 경제 변화 이론들의 동향을 탈포드주의적(Post-Fordism) 입장에서 고찰해 보기 위한 것이다. 이러한 목적을 위하여 우선 80년대 이후 서구 학계의 대도시 경제변화 이론의 전개 과정을 포드주의에서 탈포드주의로 세계 경제 체제가 변화하는 흐름과 관련지어 살펴보면서, 대도시경제 변화의 주요 경향들과 그 원인들을 살펴본다. 이중 특히 경제체제의 유연화에 따른 도시 경제의 변화 과정을 설명하려는 스코트(A.J. Scott) 등의 신산업공간(지구)론과, 정보통신기술의 발달에 따른 도시 경제의 변화 과정을 설명하려는 카스텔(M. Castells) 등의 정보도시론, 90년대 이후 제도주의 및 네트워크 패러다임 아래서 연계, 지식, 학습, 제도의 중요성을 강조하는 클러스터 및 지역혁신체제 이론을 집중적으로 조명해 본다. 한편 최근 세계 주요 대도시 경제에서 나타나는 일반적 경향인 사회 양극화 및 도시의 이중구조화에 관해서도 관심을 가지고 고찰한다. 마지막으로 이들 이론이 우리나라 대도시 연구에 갖는 시사점을 간단하게 짚어본다.
