The most of public services that we use these days is distributed and supplied as 'App' service because of wide spread of smat phones. Especially, since the interest of general citizens about usabilitu of public data has been increased, in case of Seoul, people can reach the data through 'Seoul Open Data Plaza' of 25 regions of Seoul. It becomes possible to construct various throughout this system. Ultimately, in case of users, they are provided many services through their electronic media. Looking at the development and research of public data service, they are mostly focusing on service or building up the service, but the research on visualization of contents is insufficient. This study is suggesting the specific plan and directionality of building public service using the public data which studied in the advanced research, "The user interface platform". Finally. this research is for a right usage of public data in the smart urban environment in near future and providing the practical public service.

Korean government has launched a new public rental housing policy for younger generation suffering from instable housing conditions in CBD area. This paper is to analyze the financial feasibility of urban public rental housing projects, based on its cash flows. Urban rental housing projects should find out the way to reduce costs and to secure cheap land, because of the high land price in CBD area and complex relationship of legal rights. Project types are categorized by the land acquisition method and district characteristics. For 10 sample projects, financial feasibility was analyzed. Cash flows were calculated on the design plan and 16 scenarios were made by combining 4 important variables. The variables are increase rate of land price, increase rate of monthly rents, ratio of public and market rents, and the interest rate of National Housing Fund. The findings are as follows. Government land rent-type can reduce initial costs because it is not necessary to buy land. However, total NPV is lowered at the time of liquidation due to the land return. Private land acquisition-type require more initial costs. But the NPV at liquidation time increases with land disposal. To improve financial feasibility, acquisition-type should be preferred in high land-price area and rent-type should be preferred in low land-price area. Among influencing variables, the rate of increase in land price and the ratio of public and market rents turned out to be the most important. Although the ratio of public and market rents can be controllable, high ratio will cause the burden of tenants. Therefore, interest rate adjustment of National Housing Fund is more desirable.

Urbanization and industrialization have led to a severe deterioration in urban air qualities. As an air pollution is closely associated with human health, citizen has a growing concern about the air quality policy to improve their residential environment. Due to the recently advance in web- and mobile computing technologies, citizens can easily access various air quality information and public authorities utilize the social media service to communicate citizens with air quality issues. Also citizens' participation and role has been increased to improve urban air qualities. Thus, to meet the technical and societal changes, a GIS-based air quality information system is developed based upon the Ubiquitous Public Access (UPA) model in ISO19154. The proposed system employs the context information model to provide air quality information depending on citizens' health conditions and locations. Also, citizens can present their perceptions of an air quality at their current location Public authorities can thus utilize the citizens' perceptions when establishing new air quality policies.

This study discusses the features of the lighting and ventilation regulations for residential buildings in Hong Kong. Given the compact built environment and public concerns about the environmental quality of housing, various lighting and ventilation regulations have been enacted in Hong Kong. The application of building regulations on the micro scale and incentive systems on the macro scale are present, and the governments' calls for more active participation of the private sector and use of the building environmental assessment tools were also noted. Unlike South Korea, however, Hong Kong was found to adopt more performance-based standards, consider the external factors of the lighting and ventilation conditions together with the indoor elements, and provide specific design guidelines. Notwithstanding the different climatic conditions and socio-political contexts of Hong Kong and South Korea, these findings provide some policy implications for the South Korean government in its efforts to achieve a healthy environment for high-rise, high-density housing. It is suggested that the South Korean government adopt more on-site measurement methods to reflect the environmental conditions accurately and broaden the scope and scale of the implementation of the lighting and ventilation regulations with more specific, practical planning and design guidelines.

Existing buildings in urban parks are a kind of thing that has been settled and occupied on the site of an unexecuted park. The aim of this study is to identify nature by analyzing the causality and path-dependency through the transformation of the relevant system. The scope of the study was set up as a system for the occupancy of urban parks from 1934 when the building restriction system was established to 2000 when purchase claim (매수청구권) was introduced. The method of study was to get correlation by harmonizing the external and internal mechanisms affecting the relevant institution. The related system showed a modest change in the fourth stage, polymerizing the initial system. In the 1950s and 1960s, the existing buildings in urban parks were 'disguised' by government and the 'regulation' principle was applied since 1967. In the 1980s, the principle of 'protection' and 'support' for parks was added, but in the 1990s, the principle of regulation began to be lifted as the long-term unexecuted urban park (장기미집행 도시공원) problem continued for more than 60 years. Although the public concept of land ownership (토지공개념) has worked strongly for nearly 30 years since 1960, the system has developed into a form of deregulation since 1980. The nature of the relevant institution is first, dependent on the higher-level system and vertical. Second, it implies a conflict of restrictions and acceptance. Third, it is a temporary measure of the park problem. Therefore, the relevant system has long been enhancing the encroachment requirements on urban parks, so fundamental readjustment is needed in the future.

The primary goal of this research is to link two currently disconnected literature; the history of urban redevelopment and the one of urban parks and open spaces in the United States (US). Through this exercise, this study attempts to reveal examples of urban parks and open spaces that have yielded economic effects, and emphasize their possibility as a measure of urban redevelopment. Five phases are presented, starting with two Pre-World War II urbanization periods, and three subsequent periods of Post-World War II urban redevelopment (1940s~1960s, late 1960s~1970s, 1980s~present). While urban parks in the 19th century urbanization period held a preeminent place in urban design, policy and economy, ensuing depression and World War II diminished their role as a channel to ease unemployment. In the first phase of urban redevelopment, the economic motive to build open space was to boost the appeal of specific locales in order to draw people and businesses back to a neglected city. In the second phase, public effort to create and maintain urban parks and open spaces declined due to the budget austerity, instead, community open spaces flourished through the voluntary actions and helped neighborhoods to regain desirability. In the third phase, the aspirations and functions of such projects resemble their forerunners of the first phase, but their targets extended to global businesses and elites.

Violent crimes have increased continuously due to the development of urban society and have become a threatening factor against the residential safety of citizens. The prevention of these crimes is always a major topic in human society and one of the fundamental elements of the quality of life and safety of citizens. In recent years, much attention has been paid to environmental design through the Crime Prevention Through Environmental Design (CPTED) as a preventive measure. Currently, South Korea is promoting the openness and utilization of public data, and crime prevention is one of the fields that can utilize public data actively. This approach to crime prevention utilizing public data will be helpful for the proposal of policies from new viewpoints departing from the general utilization measures of CPTED that improve streetlights and closed-circuit television (CCTV) installations, whose limitations have been pointed out as they are only mechanical surveillance. Thus, this study sets the research scope based on the statistics of the status of five criminal offenses by administrative district in recent years provided by the data portal in Seoul City, the capital of South Korea, as the utilization data and concentrates on the analysis. Based on the analysis results, this study proposes a method to utilize classical music as a new policy for regions where the improvements are most needed. The open-source Python analysis program was employed as the main data analysis and visualization method.

The aim of this study is to be able to understand the problems within the urban agriculture policy promoted by the Government and local autonomous entity base on the comparison of the consciousness of the urban agriculture between urban farmers and public officials and to inquire into the further revitalization scheme in the end. For this purpose, this study drew implications through studying latest trend and the legislation of domestic and foreign urban agriculture and then conducted a questionnaire survey of urban farmers and public officials. Because of this research, the revitalization schemes of urban agriculture are as follows: First, it's necessary to secure the usable arable land, such as the green roof, community garden, as well as urban agriculture park, etc. Second, it is necessary to establish the urban agriculture relations act suited for the actual circumstances of our country and to back up the legislation at an institutional, technological level in terms of a nation in order to secure the durability of urban agriculture. Third, it is advisable to make a proposal about the problems in time of activities for cultivation by forming a network between urban farmers and public officials and to prepare the plan for the active exchange of farming technologies. Fourth, it's necessary to activate the community gardens by supplying the education through cultivation method & its management method, and a variety of urban-agriculture-participation programs. Fifth, it is necessary to set up the specialized and practical education through an institute for landscape architecture. Sixth, it is necessary to induce the spontaneous participation in urban agriculture from urban farmers accompanied by the activities for promotion that are worth arousing urban farmers' interest. Lastly, it is also necessary to establish a legal basis of urban agricultural parks and facilities as well as to promote a search for multilateral policies and their practice so that the further urban agriculture can be stably continued within city boundaries.

Community-based housing is widely recognized as one unique mode of affordable housing provision discussed in the agenda of urban housing policy in the midst of global economy. While economic development of rural communities are severely blocked by many factors, the local housing needs at grass roots level are addressed in the response to the growing number of the elderly and shortage of adequate housing to accommodate the group, and the availability of affordable housing is primarily seen as a viable option to the sustainability of rural community. This research study is to examine the case study of community-based housing development in rural areas, and to explore the drives and hurdles that influence the success of each development. The on-site visits and in-depth interviews with community leaders were employed to meet the research goals. The findings show that the driving factors making the successful housing development include the firm commitment to the importance of affordable and adequate housing, strong leadership of community leaders, public support, well-advised dispersion of public resources and strong bond between the public sector and local people. In spite of all the contributing factors, the unfamiliarity of collective ownership is the leading hurdle to proceed the development in a timely manner.

Due to the growing interest in eco-friendly and sustainable design in the architectural and urban planning field, we are witnessing numerous projects in which old buildings are being reused. However, with the exception of domestic apartments, there hasn't been a systematic approach or policy regarding the reuse of specific building types. On the other hand, we were able to point out two public building types, dong-offices and primary schools, that are expected to be underused, with future needs for conversion. Because the two building types are public buildings, we believe that their conversion must address the needs of the society. In this study, we have chosen 'social integration' as the ultimate goal of reusing public buildings. Upon the conceptual model of 'Housing-Mixed Public Facility', which was produced in a previous study, we have added other core programs that could be adopted into the model. Then, we applied the improved model onto the two building types by producing conversion plans and introducing key planning techniques. During this process, we have found some regulations that would not allow the realization of some models. Therefore, we have suggested amendments to the related regulations.
