As the complexity and diversity of modern urban development increases, the importance of external space planning in urban development projects is growing. This study analyzes the importance and characteristics of each major to enhance the utility value of external space, which aims to improve the efficiency of external space planning and ultimately improve the quality of life of residents. To this end, we reviewed relevant literature, legal guidelines, checklists, and guidelines, and derived 17 external space indicators through expert surveys and FGIs, and organized them into five major categories: accessibility, connectivity, suitability, stability and locality, and landscape planning through FGIs with experts in architecture, urbanism, and landscape architecture. As a result of the analysis, urban planning and design majors prioritized planning that considers the hierarchy and characteristics of the landscape structure, securing public space through the connection of open spaces and pedestrian paths, and connecting organic and three-dimensional buildings, streets, and parks; architectural planning and design majors prioritized harmony with the surrounding environment, securing public space through the connection of open spaces and pedestrian paths, and connecting organic and three-dimensional buildings, streets, and parks; and landscape (environmental) and landscape majors prioritized harmony with the surrounding environment, connecting with adjacent buildings, streets, parks, and green spaces, and planning with integrated landholdings. This emphasizes that urban development projects should secure publicness and integration through harmonious connections with adjacent buildings, streets, parks, and green spaces. This study developed evaluation indicators for evaluating the external space planning of urban development projects and quantified them through the hierarchical analysis method (AHP), which will be useful for future policy formulation and practical application in the fields of urban planning and design, architectural planning and design, landscape (environment), and landscape architecture.

Applying an external electric field across air filter media is one of methods to improve the filtration performance. Metal wire meshes have been commonly used as electrodes situated on both sides of a thick filter pad. For a thin filter medium a short circuit, known as the biggest drawback for applying an external electric field to air filter, can occur at the closest point between electrodes. In this study several types of insulated meshes were prepared by coating #50 meshes with a dielectric material, Nylon 66, and the filtration property of air filter was evaluated at the presence of external electric field using those insulated meshes as electrodes and compared with that of filters using bared meshes. The collection efficiency of tested filter was increased from 78% to 95% for singly charged 100 nm particles by application of external electric field. As a result, there was no significant difference in collection efficiency between filters with insulated and bared electrodes. Similar results could be also seen from the tests using polydisperse particles. Finally, through this study, we found that the insulation of mesh electrodes doesn't affect the filtration performance of fibrous air filter under external electric field.

In this study, in order to improve the seismic performance of existing reinforced concrete (RC) framed structures, various external attachment of corner steel frame configurations was considered as a user-friendly retrofitting method. The external steel frame is designed to contribute to the lateral stiffness and load carrying capacity of the existing RC structure. A six-story building was taken into account. Four different external corner steel frame configurations were suggested in order to strengthen the building. The 3D models of the building with suggested retrofitting steel frames were developed within ABAQUS environment using solid finite elements and analyzed under horizontal loadings nonlinearly. Horizontal top displacement vs loading curves were obtained to determine the overall performance of the building. Contributions of steel and RC frames to the carried loads were computed individually. Load/capacity ratios for the ground floor columns were presented. In the study, 3D rendered images of the building with the suggested retrofits are created to better visualize the real effect of the retrofit on the final appearance of the façade of the building. The analysis results have shown that the proposed external steel frame retrofit configurations increased the lateral load carrying capacity and lateral stiffness and can be used to improve the seismic performance of RC framed buildings.

Purpose: Recently, Housing area plan has tried to reflect a public space of various forms. However, most of cases are indiscriminately developments, which don't reflect the diverse needs of residents. In addition, a subject of the public space is not clear and consistently stable of the management, so the residents don't have an interest enough to take advantage of it. Method: In order to make a plan of the public space of a residential complex, an architect designer needs to take a few things into consideration. One is a physical facility in needs. And other one is a management of keeping a social place stably and consistently, which allows residents to be able to interact with each other. It should be regarded for residents to form a sense of belonging, while minimizing the interface friction. When all these problems are fulfilled, an interaction will be made to improve the quality of the living environment. Result: Therefore, in this study, it is necessary to define the meaning of territoriality of the external public space of housing complex. This study makes it possible to improve the relationship of neighborhood and the quality of the life for the residents, depending on the time. This is the first step as 'the research for the territoriality of the external public space of housing complex', in order to define about the concept, function, characteristic of territory(the base of territoriality) and to establish the territoriality that can form the physical or psychological boundary in public space.
