The objective of this study is to investigate the functional conformity based on the analysis of the spatial connectivity of block housing using space syntax. Three cases were selected which have important meanings in 1920s. The properties of spatial configuration were derived from an urban-context approach and without urban context analysis, and spatial connectivity and functional conformity were analyzed using references. The results of the study revealed that the arrangement of block housing were different from one another notwithstanding their similar layout characteristics. The relationships between urban streets and housing complexes were identified, and the public spaces were being arranged as semi-public spaces, whereas blocks as private spaces by separating functions. This study provides the implications for the planning of low rise-high density housings by means of analyzing the spatial connectivity of the spatial layout characteristics of European block housing, recognizing the relationships between urban communities and housing complexes.

The design principles of new urbanism (NU) have been adopted for new towns-in town projects for inner city neighborhoods in Seoul, Korea Since 2000. Here, ten NU principles were matched to four urban design categories: streets, land use, housing and buildings, and public open spaces. These elements were analyzed for Eunpyung New Town project. Through the case, the applications and implications NU principles are explored. The principles of connectivity, quality architecture and urban design, increased density, green transportation, sustainability, and quality of life were positively and successively adopted for streets, land use, housing and buildings, and public open spaces. The principles of mixed-use and diversity and traditional neighborhood structure were only partially applied in land use, housing and buildings, and public open spaces. It should be note that the walkability principle is intended not for job-housing proximity, but for pedestrian-friendly street design.

The paper begins with the idea of the society of the continued rooms that building connects architectural space (building interior) and urban open space (urban interior) or countryside/rural open space (territorial interior). It gives an account of, through literature review, a theoretical possibility of integrating not only architecture and urbanism but also architecture and countryside/rural planning. The first site explores the continuously articulated and connected spaces between building interior, urban interior, and territorial interior, in understanding Alberti's analogy, "A house is a little city." (1452) The second site illustrates architecture as an open boundary and a spatial medium which makes building, urban, and territorial interiors connect and makes them continuous. There is an opportunity of reading the continued relations and the continua of spaces. The third site deals with the form of building that architecture creates for building interior (society of rooms) and urban interior (society of urban rooms), and moderates the interiors. The last site clarifies the territorial interior (society of countryside/rural rooms) that constitutes homogeneous spatiality moderated by architecture between building interior and urban interior. The paper discusses the society of the continued interiors(building/urban/territorial interiors) that ought to be a fundamental truth in the field of every project which deals with a unit of space. It logically clarifies the society of the interiors, not isolated and blocked off but multilayered and continued. It comes to the conclusion that the territorial interior should be subsumed under the design field and the society of the continued rooms ought to be considered as a united object of space in the fields of interior architecture/design, architecture, landscape, urbanism and countryside/rural planning. Ultimately, it aims at offering a departing point of discourse and a theoretical foundation for the future studies on urban interior and territorial interior.

Major and reckless development which have been continued during the last half century, have caused decrease and damage of urban green spaces in the point of qualitative and quantitative view. Particularly, it brought about reduction to urban neighborhood park which has taken the main role for landscape ecological value. Recently, neighborhood park planning based on the landscape ecological results has been increasing gradually. Most of all, diverse attempts such as the application of shape character analysis and the step of landscape ecological planning in urban park planning have been proposed. Today, we recognize the importance of comprehensive approach in urban green planning and neighborhood park planning, but landscape ecological approach which is analyzing character and making proposal with isolation, connection and circulation is still insufficient. Most of neighborhood parks in Korea are surrounded by buildings and isolated from adjacent green spaces. Besides, these parks have landscape ecological problems such as reduction of size, isolation from adjacent green spaces, decline of nature, and excessive pavement which we ignored during urban development process. We have sympathy for understanding landscape ecological characters and considering improvement proposals for neighborhood parks Therefore, the purpose of this study was to 1) select five neighborhood parks in Daegu, 2) analyze landscape ecological characters with isolation, connection and circulation, and 3) compare data. It is certain that these results should be the main data for the arrangement of improvement proposals which landscape ecological characters were appled to.

Urban Heat Island (UHI) is caused by an energy imbalance in urban areas, where building design and land cover contribute to its amplification. To mitigate UHI, increasing green space is one of the well known and the most effective approach. This study aims aimed to identify specific components of green spaces that lower temperatures and demonstrate the cooling effects based on their size and composition. Forests within green spaces have had a greater impact on temperature reduction due to shading and blocking solar radiation. Although lakes also contributed to temperature reduction, the effect to cooling intensity was not significant. The cooling distance does not depended on green space size or composition. The study emphasizes that initial temperature has a strongerinfluence on cooling intensity than green space size, highlighting the importance of vegetation type within green spaces to achieve a cooling effect. These findings provide valuable insights for urban planning and the design of green spaces to mitigate the effects of the urban heat island.

This study predicted urban green spaces for 2020 based on two scenarios keeping or freeing the green-belt in the Daegu metropolitan city using a hybrid Cellular Automata(CA)-Markov model and analyzed the spatial dynamics of urban green spaces between 2009 and 2020 using a land cover change detection technique and spatial metrics. Markov chain analysis was employed to derive the transition probability for projecting land cover change into the future for 2020 based on two land cover maps in 1998 and 2009 provided by the Ministry of Environment. Multi-criteria evaluation(MCE) was adopted to develop seven suitability maps which were empirically derived in relation to the six restriction factors underlying the land cover change between the years 1998 and 2009. A hybrid CA-Markov model was then implemented to predict the land cover change over an 11 year period to 2020 based on two scenarios keeping or freeing the green-belt. The projected land cover for 2009 was cross-validated with the actual land cover in 2009 using Kappa statistics. Results show that urban green spaces will be remarkably fragmented in the suburban areas such as Dalseong-gun, Seongseo, Ansim and Chilgok in the year 2020 if the Daegu metropolitan city keeps its urbanization at current pace and in case of keeping the green-belt. In case of freeing the green-belt, urban green spaces will be fragmented on the fringes of the green-belt. It is thus required to monitor urban green spaces systematically considering the spatial change patterns identified by this study for sustainably managing them in the Daegu metropolitan city in the near future.

A sound-masking technique was applied to the urban public spaces with multiple noises in order to reduce the annoyance of the construction and traffic noise. In addition, the effects of masking system were investigated in order to improve the soundscape. In several urban spaces, building construction and nearby road traffic noise were recorded using a head and torso simulator and sound quality (SQ) system which specifies the spectral and temporal aspects of the noises. The sound-masking system which consists of the distributed speakers and control devices was applied to the boundaries of the construction sites. Synthesized masking sounds were produced with consideration of SQ characteristics of the multiple noise. Subjective evaluations on the soundscape were conducted to verify effectiveness of the system under the conditions with and without the masker sounds.

The purpose of this paper was to classify areas demanding to be transformed to green spaces and evaluate their grades for urban park and green networks. The results of this study are summarized below; 1. The results of the classified green spaces in the research areas fall into three types including children parks, neighborhood parks, and public green spaces. The three types of green spaces were analysed with recreational indexes. The zones disturbing the green-networks were sorted out. These zones should be changed into a supplementary green spaces for improving the recreational functions in the city. 2. For urban park and green networks, distances between the parks and size of the parks were adopted as indices. Based on the index of distances between the parks, disturbing zones were evaluated with 3 grades. The first grade includes primary industrial complexes and housing complexes. The second grade was observed mostly in industrial complex areas. The third grade includes housing complexes. Based on the indexes of size of parks, disturbing zones were evaluated with 2 grades. In the case of grade I, it appeared in housing complex. In the case of grade II, it appeared in industrial complex. 3. Then, we prioritized the disturbing zones with severity in order to make supplementary green spaces. Through the process, the zones of the grade I for two each recreational index were evaluated to two grades. The analysis results of evaluated zones were that grade II appeared over industrial and housing complexes widely. Grade I appeared over housing complexes. 4. It is necessary that the grade of disturbing zones should be considered as an order to make green spaces to supplement a green-network. For this, we formed a basic frame of a green-networks in Dalsu-Gu and placed the disturbing zones on the basic frame of a green-network. Consequently, The results were that the green-networks in Dalsu-Gu was composed on four green-network axes and its shape mirrored a cruciform (+) of northwest$\leftrightarrow$southeast direction and southwest$\leftrightarrow$northeast direction.

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.

There has been various pedestrian-friendly planning for making walkable cities. However, the representation of urban pedestrian spaces that should be the basis of the pedestrian-friendly planning tends to be far from reality. This is due to the absence of a consensual way to represent pedestrian spaces in the city. In this context, this study aims to propose a method to properly represent pedestrian spaces. For this purpose, this study first reviews the patterns of representing pedestrian spaces appearing on city maps and examines their merits and limits. After that, the criteria of pedestrian traversability and the mapping method are proposed on a trial basis for representing pedestrian spaces. Then, applying this to the case sites, Mokdong and Euljiro, this paper demonstrates how the operation of representing pedestrian spaces works. It is expected that the results of this study would be used as the basic foundation for a more developed representation of effective pedestrian-friendly planning.
