Since the industrial revolution, the global environmental problems such as greenhouse gas accumulation and the average temperature increase have caused people's attention. 'Low Carbon, Green Growth' was presented to cope with these global concerns, as one of main policies of 2008 in Korea. The paradigm of a green urban development is started to concern the whole city's energy problems owing to realize 'Low Carbon, Green Growth' in the urban side. The government established a nation's basic energy plan for 20 years, and some local cities made efforts to develop new renewable energy such as the solar, wind and water energy which are suitable to each city's character. As a part of these efforts, the concept of U-Eco city is newly appeared to reflect upon ubiquitous technique, urban ecology and the next generation energy system. However, urban plan is difficult to adopt this next generation energy system with existing laws, regulations and technical systems. The new executive and systematic system is needed to realize the U-Eco city U-Eco for the management of an efficient city. In this study, the authors investigate the concept of the next generation energy system and U-Eco city to realize the energy-efficient city plan and analyze problems to occur during the application of them in an existing city plan. Then, the authors show the remedies to deal with occurred problems.

In the 1960s, polluted urban streams were covered and paved in concrete. Rivers became sewers buried under road. As a result, wildlife habitat was lost and the open stream space was gone. In the 1990s, there was a movement for restoring urban streams to enhance the quality of life of inhabitants. Chungkye Stream, whose covering began from early 1950s and ended in 1977, is now in the process of restoration together with the Central Business District (CBD) Redevelopment Plan. However, as the construction proceeds, several problems were raised, and serious controversies resulted. Therefore, this study aims to investigate the validity of the approach of the Chungkye Stream Restoration Project through a literature survey and a site survey, and to present the improved alternative. Ultimately, the study aims to contribute to present references or guidelines for similar urban stream restoration projects. The Chungkye Stream Restoration Project has some of the following problems. First, the construction should be done based on the long-term urban redevelopment plan. Second, the construction period should be extended to restore urban streams. Third, the cultural asset conservation plan should be implemented. In order to fulfill the anticipated purpose, the above mentioned problems need to be solved.

Purpose: The small-scale environmental impact assessment conducted during the development project stage has focused on the preservation of the natural environment centered on non-urban areas, due to the nature of urbanization, health problems for citizens of high-density urban areas have a limitation in that they are relatively neglected. In the case of strategic environmental impact assessment and environmental impact assessment in urban areas, there is no basis for evaluation in urban areas because there are exceptions to be excluded from the target projects or there are no target project regulations for buildings. Therefore, in this research, we examined the problems with the target project such as the current environmental impact assessment, and tried to establish a system improvement plan that can solve them. Research design, data and methodology: After reviewing the current environmental impact assessment-related laws (including enforcement ordinances) and national land planning laws (including enforcement ordinances), exceptions such as environmental impact assessment in urban areas were identified and problems were identified. Based on this, an amendment to the Enforcement Decree was proposed to provide institutional support for the expansion of target projects such as environmental impact assessment in urban areas. Results and Conclusions: Through this research, it is expected that the projects subject to environmental impact assessment on development projects in urban areas directly related to the health of the people will be expanded, and the net function of the environmental impact assessment system will be maximized.

최근 우리나라에서는 도시공간구조를 자동차 중심형 에너지 다소비형에서 대중교통과 보행을 우선하는 형태로 재편하여 대중교통이용자의 편의를 도모하는 동시에 에너지소비를 줄이려는 노력이 확대되고 있다. 우리나라의 도시는 미국과 유럽의 도시들에 비해 상대적으로 고밀로 개발되어 있고 대중교통서비스도 상대적으로 양호하여 대중교통중심형 도시구조로의 발전 잠재력은 매우 높다고 할 수 있다. 그러나 현재 우리나라의 도시들은 선진국의 주요도시들에 비해 대중교통수송분담률이 낮고 도시환경의 질도 상대적으로 낮다. 본 연구의 목적은 우리나라 도시들이 대중교통중심형 도시로 탈바꿈하기 위하여 풀어 나가야 할 도시구조상의 문제가 무엇인지 분석하는데 있다. 이를 위해 본 연구에서는 수도권 내에 위치한 대중교통결절점을 중심으로 실태를 조사하여 토지이용밀도, 토지이용복합성, 보행편의성, 대중교통연계 측면에서의 문제점을 분석하였다. 또한 분석 결과를 토대로 우리나라 도시들이 대중교통중심형 도시공간구조로 전환되기 위한 도시계획 측면의 개선방향을 제시하고자 한다.

Air pollution in urban areas of Korea is considered in significantly serious level because of population exceeding the capacity and diversified facilities for the activities in socioeconomic field, education, politics and even cultural society in confined areas. Korea is one of the most populated countries and the largest five cities occupy 2.4% of total area but 45% of total population. Patterns of urban air pollution are also changing due to the change of emission sources and fuel usage. Essential recovery of urban environment in Korea has become extremely difficult and necessitates enormous investment. Accurate understanding of problems should be pursued for the efficient and effective improvement of the environment. In this article, air pollution phenomena in urban areas are analyzed mainly with respect to recent urban air pollution trend and pollution sources and possible control strategies are discussed : 1) source control-stationary and mobile, 2) air quality management strategies, 3) research and development.

Most surveillance systems of urban transit are based on CCTV(Closed Circuit Television). However, there is limitation that the passive monitoring system using CCTV in urban transit surveillance system to monitor massive environment applies thousands of cameras and it depends on operator's instinctive judgement whether it happens an accident or disaster. Urban transit operation corporations try to introduce the intelligent technology to overcome these problems as mentioned above. The intelligent system can be organized various ways and made configuration for purpose and function. In this paper, we describe the configuration problems of the existing surveillance system and propose the proper intelligent system configuration for urban transit We expect that the proposed configurations are very helpful to introduce the intelligent technology for urban transit surveillance system.

Background and objective: With the revision of the Act on Urban Parks, Green Areas, Etc. in 2013, the "urban agricultural park" was newly established under the subcategory of "themed park," thereby establishing the institutional basis for the creation of urban agricultural parks. However, urban agricultural parks are still in the early stages of their introduction. There is a lack of research on direction setting and specific operation management that considers urban residents' needs and the city's physical infrastructure. Methods: We utilized the public service design process suggested by the Ministry of the Interior and Safety of the Republic of Korea in 2019 to identify problems and develop directions for urban agricultural parks. The process consisted of the following four steps: Understanding, Discovering people's needs, Defining real problems, and Developing ideas. Results: As four types of ideas for revitalizing urban agricultural parks, 'information users want to know,' 'user participation in design,' 'venue for local communities,' and 'urban agricultural parks as health and rest areas' were derived. This means that urban agricultural parks must provide the information users want; users must plan, decide, and implement such information by directly participating in the creation and efficient management and operation of urban agricultural parks; and urban agricultural parks must be used as a venue for local communities. Urban agricultural parks should also be spaces for health and relaxation. Conclusion: Urban agricultural parks should avoid the unified space and passive participation patterns of existing urban parks, and become real spaces for resident participation that can satisfy all the production, leisure, landscape, ecology, and psycho-social needs of the users of urban agricultural parks. Furthermore, it is necessary to introduce a more systematic and diverse operating system so that it can work to revitalize the local community and connect organically with the function of the city.

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.
