  • During the 2000s there were changes in the educational facility policy having impact on school architecture, such as departmental classroom system by the 7th national curriculum and BTL projects. Especially for secondary school architecture with the new keyword of 'departmental classroom system' unlike elementary school with the well-known keyword of 'open classroom', the emergence of new school architecture was anticipated. For these reasons it is worth while to notice secondary school architecture in the 2000s and this study aims to review the architectural characteristics of middle schools as first step. Cases of 18 schools selected by EDUMAC were analyzed focused on site planning and planning characteristics of each spaces. Through the analysis, the architectural characteristics of middle schools in the 2000s are summarized and comments on some problems are made. In summary, case schools have typical characteristics of Korean school architecture in unit classrooms and block plan for daylight condition. On the other hand, they have more diversity in space organization and facility program. But it leave something to be desired in expressing urban architectural characteristics, traditionality and locality with searching for new school architecture.

  • This study was conducted to analyze the effect of the different land covers of an urban park (Hyowon park) in downtown Suwon on the urban thermal variations during a hot summer. The effect of the air temperature reduction in the urban park was 4.4%-4.5% for the downtown residence (Maetan-dong). This value was about 0.8% lower than that of the outskirts residence (Sanggwanggyo-dong). The daily mean temperature, daily maximum temperature, summer day and heat wave frequency were measured under the different land covers (cement-block, grass, pine-grass, shading area and mixed forest) showed these values generally decreased under natural land cover types. Daily minimum temperature and tropical night frequency didn't seem to correlate with the land cover types. Means of thermal comfort indices (wet bulb globe temperature, heat index and discomfort index) in the shading area, mixed forest and the pine-grass types were lower than those of cement block and grass types. However the levels of those indices were equal to 'very high' or 'caution' levels in the afternoon (13:00-15:00). In the morning (06:00-08:00), thermal comfort indices of the urban park didn't correlate with land cover types. Therefore, to reduce heat stress and to improve the thermal comfort in urban parks, an increase in the area of natural land cover such as grass, forest and open spaces is required.

  • The rate of automobile ownerships has been increased significantly in multi-family housing sites so that government has made new parking regulations increasing the rate of parking supply by the high demand of parking lots in multi-family housing sites. However, the new regulation of parking supply has several problems that it applies to only new multi-family housing sites and disregards to the locational distinctions around the sites. It also has reduced to the open spaces in the sites and increased the price of housing units especially to the small size units of multi-family housing sites by increasing the number of underground parking lots. Furthermore, the residents have not been equal opportunity to access their parking lots even though they have been charged to equal amount of financial burden for the construction of underground parking lots. This research aims to relieve above problems by analysing parking supply and demand management strategies both domestic and foreign countries, and suggest to new parking management system for multi-family housing sites in 21st Centuries. This research reveals that most of multi-family housing sites want to be applied 1) diverse parking supply regulations considering the locational distinctions of sites, 2) parking lot ownership programs, 3) charging parking fees to second vehicles, 4) increasing parking lots both in the sites and around the sites, 5) enforcing police power to the parking violation vehicles to their sites. Especially, the multi-family housing sites consisting of small & medium size of units and locating in small & medium size of cites strongly want to be accepted new Parking regulations considered their locational and social distinctions and applied police power to the parking violation vehicles in their sites compared to the other multi-family housing sites.

  • Ettringite and thaumasite were observed in some concrete. The morphology and occurrence of these minerals were closely examined by performing SEM/EDAX analyses. We also experimentally induced the concrete deterioration using $Na_2SO_4$ solution with application of various environmental conditions. The stability of these minerals and deterioration characteristics under applied experimental conditions were determined. Abundant ettringite formed by“through solution reaction”occurred in many open spaces, and some microscopic ettringite formed by "tophochemical replacement" of calcium aluminate also occurred in cement paste. Severe cracking of cement paste causing premature deterioration was often associated with ettringite location. Under specific condition, ettringite was transformed to thaumasite, tricthloroaluminate, or decomposed. Thaumasite occurred with association of ettrinsite in concrete containing carbonate aggregate being subject to dedolomitization or in some concrete being subject to carbonation. Thaumasite appears to be formed under the similar condition to the general ettringite forming condition, but it formed solid solution with ettringite by substituting pre-existing ettringite. Ettringite can also be transformed to trichloroaluminate in the presence of abundant chlorides, but trichloroaluminate changed back to ettringite in late sulfate attack. It is considered that the substitution reaction direction solely depend on the concentration of chloride and sulfate ion.

  • Due to the amendment of the Act for Urban Parks in 2005, local governments have to establish long-range plans for securing and managing urban parks and green areas. This study aims to propose a method of setting priorities for green areas of land to be preserved before the development stage through the introduction of the concept of Green Infrastructure Assessment, and provide basic data to establish the network of urban parks and green areas by applying the GIA method to the city of Daejeon. The concept of GIA and the process of analysis have been drawn as a result of literature research and case studies. The results of this study show that an introduction of the GIA concept to set park and open space planning promotes the connection of the city planning process as well as presents very a reasonable source to facilitate sustainable development. Also, other results present a priority ranking for protection of parks and green areas as well as a means to manage potential focus areas. This study, does have research limitations such as a limited study area, scale, and conflicts between domestic and foreign computing data. Further studies need to set the planning process and examine the index survey to apply this method to various situations and areas.

  • Pedestrians not only walk along pedestrian pathways, but also choose unusual routes such as passing through buildings or crossing large scale open spaces. This study defines these unusual paths as social path, and includes them into one of the pedestrian road categories. Previous pedestrian accessibility and route choice studies could not evaluate correctly the space connectivity or optimal route because the social path was not considered properly. Therefore, this study analyzes the effectiveness of the social path in view of space connectivity focused on Coex and Seoul stations in Seoul, which are representative transit oriented development(TOD) areas. Global integration, which is widely used in network analysis, is selected (as performance index) to identify the space hierarchy and define new pedestrian links. The study results show that the network connectivity is improved especially in the main streets and social paths. This study demonstrated that the social path should be considered in finding the pedestrian optimal route from the practical perspective.

  • On account of population aging and increasing cardiovascular disorders, acute cardiac arrest cases are escalating each year. In order to increase the survival rate of the patients, rapid cardiopulmonary resuscitation is necessary. For this reason, the government is expanding the supply of Automated External Defibrillators(AED). However, the AEDs cannot be effectively deployed to the incident cases that occur outdoors, for the installed AEDs are mostly located indoors. After analyzing the distribution of incident cases within the study area, about 11% of cardiac arrest incidents occurred in open spaces including sidewalks and residential areas. This study was conducted to increase the survival rate of the patients by allocating 41 additional AEDs in the study area using a GIS based location-allocation method. To conduct a feasibility study, the density of a senior floating population covered by the same number of AEDs placed at random and the density covered by the experiment were compared. In conclusion, having excluded outliers caused by geological and social factors, results showed that AEDs placed through GIS based location-allocation covered 5% more of the senior floating population density.

  • The present study explores the problem of the placelessness and alienation through spaces of redevelopment in South Korean animation film since the 2000's. Actual space in South Korean society has been destroyed and changed unceasingly, and, in that space, humans have experienced existential conflict. While the swift development of digital technology has transcended physical restrictions to form one great network, humans are still limited as materially based beings. The recent steps in South Korean animation film are noteworthy because sociocultural changes since the 1990's and the relationship between the individual and the system are perceived in ways different from those of the past. and , the works analyzed in the present study, reveal the special sense of place in South Korean society, where the destructive reorganization of space leads to the instability of life. By intentionally bypassing a sense of place and the authority automatically bestowed on representational images, these works prompt the viewer to reexamine the relationship between reality and images. Space in these two works are presented representationally but immediately destroyed, and humans or the characters in the works accept this unfeelingly. The loss of place, which is committed by the massive system, and listless humans' weakness and alienation in response are depicted as signs of sociocultural abnormality. By showing the destructive loss of place and individuals who respond with self-anesthesia and self-estrangement, these works open viewers' eyes to South Korean society, where not only social alienation but also self-alienation is occurring. By perceiving South Korean animation film as a sociocultural phenomenon and analyzing it through the concepts of the placelessness and alienation, the present study seeks to expand further discussions on animation film.

  • The purpose of this paper is to understand the value of Dongji(東池), Seoji(西池) and Namji(南池), the lotus ponds of Fortress Wall of Seoul as part of the cultural landscape of the period through a consideration of personal behavior and impressive landscape characteristics via various old writings on each pond. The objects of this study include poems, diaries, travelogues and essays describing these ponds. The results are as follows. First, the preferred landscape elements of these three ponds were lotuses, willows and water itself. Second, while Dongji was recognized as a natural landscape, the composition of Seoji was a mixture of with natural and urban landscapes, and Namji was more urban altogether. Third, in aspects of personal behavior, while Dongji was a place where people broke their journeys to gaze at the scenery or looked down distantly, in Seoji, people stayed for a long time in a pavilion called Cheonyeon-jeong(天然亭) and engaged in various leisure activities, and in Namji, there were many gatherings under a temporary shelter or at a friend's house near the pond. Night was the best time to enjoy Namji because during the day, the area was crowded with people, horses, carts and so on. Fourth, the landscapes of fortress walls were impressively described often. Fifth, because these ponds were integrated into the surrounding area, they were like public openspaces mixed with water spaces, natural environment and adjacent facilities. The lotus ponds of the Fortress Wall of Seoul were located in a place connecting inside and outside of fortress, supplemented the cultural features in city, were valued as public openspace, and made it possible to experience the unique landscape of Hanyang. Although these ponds were buried and have now disappeared, they still hold great cultural meaning and potential value as water landscapes of the old city.

  • The purpose of this study is to identify land use types and to develop and evaluate biotope maps for Gangseo-Gu (ward) in Busan Metropolitan City, South Korea, using the Degree of Hemeroby. Hemeroby is a measurement concept or tool to assess the magnitude of human impact on ecosystems. Gangseo-Gu is the second largest Gu in Busan and is under strong development pressure. Before the field survey, biotopes were pre-classified based on digital maps, aerial photos and high-resolution satellite images. The method employed in biotope survey and mapping was adopted from the modified method used in Seoul, which carried out the first biotope mapping in Korea in 2000. In the field survey, a comprehensive biotope mapping method was used. The results showed that the total surface area of biotopes in Gangseo-gu was $172,620,207m^2$(42,655 acres) and there were 29 biotope types with 13,631 polygons. The ratio of urban or built-up area 22.6% and the remaining areas were forest and open spaces, of which 22.6% were actual forest areas and 35.6% were paddy fields and other field areas. The Hemeroby Index of Gangseo-gu was 54.7, which suggests that Gangseo-gu has not yet been developed extensively and needs a long-term conservation and coordinated development plan.
