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.

A map of complex environment can be generated using a robot carrying sensors. However, representation of environments directly using the integration of sensor data tells only spatial existence. In order to execute high-level applications, robots need semantic knowledge of the environments. This research investigates the design of a system for recognizing objects in 3D point clouds of urban environments. The proposed system is decomposed into five steps: sequential LIDAR scan, point classification, ground detection and elimination, segmentation, and object classification. This method could classify the various objects in urban environment, such as cars, trees, buildings, posts, etc. The simple methods minimizing time-consuming process are developed to guarantee real-time performance and to perform data classification on-the-fly as data is being acquired. To evaluate performance of the proposed methods, computation time and recognition rate are analyzed. Experimental results demonstrate that the proposed algorithm has efficiency in fast understanding the semantic knowledge of a dynamic urban environment.

An observational study of urban heat island was carried out using field data obatined during 6 days in May and August 1992 in Chunchon(population size 180.000). Air temperature was measured at 64 points along two sampling ruoutes by themisters attached to cars. Both routes cover urban and rural area and across the cneter of urban area. Continuous observation of air sonde was perfomed to clarify heights of nocturnal boundary layer(NBL) at the center of urban area. Surface meteorological observations were performed at both urban and rural sites. This study showed that heat island phenomena was obviously observed at the urbanized area during the night time with low wind speed. The average NBL heights exteded to about 10 meters, but varied with meteorological conditions. After sunset, the air temperature decreased with time at both sites and cooling rate at the urban site was greater than the rural site. The maximum heat island intensity was 7.5$^{\circ}$C at 21 LST, May 4. Usingthe two meteorological data sets obtained from urban and rural sites, the air pollutant concentration was calculated by Gaussian plume model which can obtain not only horizontal distribution of concentration but also vertical distribution. The result indicated that the concentration resulted from urban meteorological data set was lower than that from rural meteorological data set. It was also calculated that the air pollutant extended to higher level in urban meteorological data set than that in rural meteorological data set.

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.

In this study, Urban Climate Simulation was performed by 3-Dimensional Urban Canopy Model. The characteristics of urban climate were analyzed combining artificial land coverage, building size, heat production from the air conditioning and topographic conditions as physical variables which affects urban climate characteristics. The results are as follows. (1) The aspects of the urban climatal change is derived to be related to the combination of the building coverage ratio, building height and shading area. According to the building height, the highest temperature was increased by $2.1^{\circ}C$ from 2-story to 5-story building and the absolute humidity by 2.1g/kg maximum and the wind velocity by 1.0m/s was decreased from 2-story to 20-story building. (2) Whole heat generation was influenced by the convective sensible heat at the lower building height and by the artificial heat generation at the higher one over 20-story building influence to some extent of the building coverage ratio. The effect of the altitude is not more considerable than the other variables as below $1^{\circ}C$ of the air temperature. In the last, deriving the combination of building coverage and building height is needed to obtain effectiveness of the urban built environment planning at the point of the urban climate. These simulation results need to be constructed as DB which shows urban quantitative thermal characters by the urban physical structure. These can be quantitative base for suggesting combinations of the building and urban planning features at the point of the desirable urban thermal environment as well as analyzing urban climate phenomenon.

The urban park provides a safe rest and leisure area, and offers the beauty of nature to counter the drearyness of urban space. It can provide benefits such as the reduction of environmental pollution, the regulation of the local climate, and it can also provide a safe area during times of disaster. However, there was no interest in urban park development and control in Korea during the economic boom of the mid 1960s. Furthermore, during the industrialization process, the population grew significantly in the cities and the cities' scales were noticeably extended; as a result of this, the living environment and the natural environment in the cities worsened. With rapid urbanization and industrialization, urban green area diminished, and it became necessary to organize the urban park system to improve quality of life. 45% of south korea's population lives in 6 cities, which is only 4% of Korea's land size. The Urban park system has to be considered in the urban planning process. Paris' urban green system can be a role-model for Korea's urban green development plan to function organically. Urban public park concepts have been used in Paris's urban planning since 1850. There were hardly any parks, gardens and squares for the public before the middle of the 19th century. For improving life-styles for the poor, Napoleon III strongly supported the development of green space systems in Paris by G.E. Haussmann. Napoleon III and Haussmann established and applied the urban green regulation within Paris urban planning. The purpose of this study is to investigate the green regulations Haussmann's Paris urban plan and urban green space system: and as a result of this, it can be an indicator for urban green space development in Korea.

Nowadays, the discharges of urban streams during dry season are depleted because the hydrologic cycle in the watershed has been destroyed due to the expansion of the impermeable area, the excessive groundwater pumping, climate change, and so forth. The streamflow depletion may bring out severe water quality problems. This research are to investigate the hydrologic characteristics and to develop a technology to restore sound hydrologic cycle of Anyangcheon watershed. For the hydrological cycle analysis of the Anyangcheon watershed, continuous simulations of urban runoff were performed for the upstream basin of Gocheok bridge whose basin area covered 4/5 of the whole catchment area. The increase of impervious area by urbanization was analysed and its effect on urban runoff was evaluated. The SWMM 5 (Storm Water Management Model 5) was used for the continuous simulation of urban runoff. The analysis results of urbanization effect on runoff are as follows: the surface runoff in 2000 increases to 65% of the whole precipitation whereas the surface runoff in 1975 amounts to 50% of the precipitation; the groundwater runoff in 2000 amounts to 7% and shows 6% decrease during the period from 1975 to 2000.

이 논문은 수원 화성 내 도시환경의 보존형태를 분석하여 보전가치가 있는 역사적 자원들을 도출하는데 목적이 있다. 도시환경 보전에 있어 시간의 지속성을 갖춘 자원의 보호와 장소적 특징이 남아있는 자원의 관리가 중요하기에, 보존형태 분석은 물리적 형태 보존과 이용 기능의 보존 측면에 중점을 두고 수행하였다. 연구는 세 단계로 진해하였다. 첫째, 성곽 내부의 도시환경을 전체적으로 이해하고자 1911년에 제작된 지적원도와 현재의 도면을 필지의 특성을 담고 있는 지형, 수공간, 가로, 대지의 네 가지 항목으로 구분하여 비교하였다. 둘째, 도면에 기초한 문헌연구, 현장답사, 인터뷰의 내용을 토대로 도시환경의 변화내용을 연구하였고, 이를 보존-일부 보존-소멸의 척도로 구분하여 보존형태를 고찰하였다. 셋째, 도시환경에서 오랜 기간 보존되고 있는 자원과 완전히 보존되고 있지는 않지만 장소적 특징이 남아있는 자원을 구분하여 도출하였다. 연구결과, 첫째, 지형과 수계의 자연적 요소와 가로와 같은 도시구조적 요소가 크게 변하지 않았으며, 변했더라도 지반환경의 속성을 보존하고 있는 경우가 많아 과거의 도시 맥락을 이해하는데 도움을 주었다. 둘째, 지형, 수공간, 가로, 대지의 보존이 서로 밀접하게 연관되어 있음을 알 수 있었다. 이들을 보다 큰 맥락에서 통합적으로 관리해야 화성의 역사적 정취도 보전할 수 있다고 생각된다. 셋째, 현재 시점에서 오랜 기간 지속되어온 자원에는 근대에 조성된 공공시설들이 많이 있어 화성 내 역사문화자원을 조선시대 외에도 다양한 시대적 켜로 읽는 것이 필요하다. 넷째, 도시화 시기를 지나면서도 오랜 기간 보존된 필지와 가로가 최근의 역사문화복원사업으로 오히려 훼손되는 경우도 찾아볼 수 있어 이들을 신중히 다룰 필요가 있겠다.
