Recently the Korean Government is increasing investment and interest on railway in the transportation field as "low carbon and green growth" policy become main national development strategy. While railway competitiveness is weakening over the road from the inconvenient door-to-door and transfer system of railway, it is meaningful to review excellent railway transfer system of advanced countries and adapt their implications for Korea. Their transfer systems like Japan, Hongkong, France, U.K. and German can be categorized in this research as kinds of transfer & connectivity system and transfer facility & flow planning, and, as a result, their implications can be concluded. Also, analyzing transfer system of Korea's main stations and reviewing the difference between Korea and other countries, this paper suggests main principles and directions of urban planning, alignment of rail line, partnership of project stakeholder in the establishment of transfer system in the railway station in the future.

This paper focuses on how the coupling of the columns and walls through the structural slab contributes to the overall stiffness and strength of lateral systems. The rationale and procedures behind the design approach, which may offer a shift from more conventional assumptions made regarding compatibility and connectivity of gravity and lateral structural systems, will be introduced. The impacts on serviceability and strength design will be discussed, and observations on key design and analysis approaches will be featured. Mass and stiffness assumptions will also be reviewed. A case study on the topic will be presented describing implementation of slab coupling into engineering of a building project.

This study examines strategies and obstacles encountered in infusing digital resources in the middle school mathematics and science classroom. It draws on data from principals, technology coordinators and math and science teachers in three urban middle schools in United States. All three of these schools have recently invested heavily in technology hardware and high speed Internet connectivity and as such they provide an opportunity to look beyond well documented obstacles such as outdated computers and poor Internet access. The logistical, preparatory, pedagogical and curricular challenges encountered by teachers within the study have important implications for professional development efforts aimed at improving science education through the integration of Web-based resources.

Planning a major change in the domestic residential complex 'complex' in the 'city' to the influx of urban space. So, considering a set of self-environmental complex of openness and connectivity between cities inflow from residential urban housing is formed. Complex-oriented development approach and apartment high-rise and high-density regions of space and social disconnection that causes a uniform methodology that can solve the problem of housing plan, however, a recent New Urbanism New Urbanism has been introduced. And intravenous forms of communal life that occurred in the United States prior to World War II, this value is based on the main form. Design reorganizes This modern lifestyle factors (such as housing, jobs, shopping, leisure space) to go back to the traditional lifestyles while Neotradiotional Planning exercise. New Urbanism in the late 20th century, some literature refers to a postmodern approach adopted in the field of urban planning, the specific case. Actually important feature of post-modernism in the New Urbanism has been expressed. Problem is very confusing, and the principles of New Urbanism, New Urbanism, even those who claim that have different social and design views. Therefore, this study explores the postmodern tendencies of the New Urbanism, and based on this, the possibilities for the development of new towns in Korea mainly affected on the theory of New Urbanism in South Korea in Eunpyeong examine.

The purpose of this research is to develop the Habitat Suitability Index (HSI) for habitat environments of Aix galericulata (A. galericulata) and Dendrocopos major (D. major), which tend to inhabit urban environments. A. galericulata and D. major are the keystone species representing the ecosystem of wetlands and forests. Based on the analysis of their urban habitat environments, this study selects artificially adjustable levels of the environmental index in order to produce the HSI model, which can be used when either restoring or creating the urban habitats for these species. To develop the HSI, we conducted field surveys at Jungnangcheon Stream, Changgyeonggung, Jangneung, Bangbae Neighborhood Park, Gildong Ecological Park, and Seodalsan Mountain. These surveys were conducted between April and August 2020, and this period includes the breeding season of both A. galericulata and D. major. Based on our findings from the surveys, we conclude that there are six SI factors for A. galericulata. These include (1) the presence of alluvial islands, (2) waterfront vegetation cover rate, (3) type of aquatic plants for food, (4) size of forest patch, (5) type of trees in nearby forests, and (6) connectivity of waterfront and forest. We also conclude that there are five SI factors for D. major, which include (1) size of forest patch, (2) rate of broadleaf trees in forest patches, (3) type of nesting trees, (4) diameter at breast height (DBH) of nesting trees, and (5) density of dead trees. The result of this research can provide future studies with useful guidance when both (1) comparing the habitat suitability of the target species in different environments and (2) restoring or creating habitats for these species.

Hayakawa Kunihiko introduced community space as an open space in Housing in Japan for the first time. We can find the continuity of his architectural intent from his three works (Atrium, Steps, Labyrinth) during the early period of his Housing buildings, In particular, from Labyrinth, his intent was expanded to cities through 'Urban Void', seeking communication and harmony. Accordingly, based on the architectural overview and a field survey of Labyrinth, an analysis was conducted using Space Syntax to investigate whether the space of an inner courtyard is being used as a community space for neighbors who pass through the courtyard and whether the courtyard plays the role of 'Urban Void' as intended by the architect. For this investigation, according to VGA, the courtyard showed the role of great visual connectivity and integration and facilitated connections to the center of the entire space. On the other hand, according to J-Graph, the access stairway connected to each household from the courtyard helped secure privacy in the midst of common space. Step Depth noted that a hierarchy of space was formed to ensure visual privacy within each unit household in addition to privacy for each household.

The rapid urban expansion and the increase in natural disasters due to the increase of population after industrialization and climate change are causing numerous urban management problems. The IP based hyper-connectivity caused by the initiation of the 4th industrial revolution enables a variety of technologies and services that produce vast amounts of data and solve urban management problems based on this. Especially, the quality of life is improved by providing the necessary information for life that are produced through a sensor network on wired and wireless communication. In this study, we intend to propose the method of optimal communcation network composition for innovative and futuristic city management technology through the case of K-water Smart Village Communication System

According to Plato's ontology, we lead our lives by establishing a relationship with others in the society. However in rapidly changing era, our lives was gradually moving towards personal tendency. Even for the relationship with family, not with others. Thus, awareness about owning properties has changed due to the sociocultural factors and increase number of single-person households. So in this study, the considerations for single-person housing were perceived through preceding research, and the elements making spatial boundary of shared housing were drawn to make rational space sharing based on the boundary with others and of the living environment. With overall analysis based on the spatial boundary features of planned shared housing, the plan characteristics according to the spatial boundary of the current shared housing is to be drawn and analyzed. Third, The expressive and structural features of spatial boundary as above appear with mutual flexible connectivity, And the result shows that the modularity was the highest. Among them variable coupling modularity of shows how it is possible to combine efficiently and variously the private and public spaces with regularity of 'space of optimal unit'. This study drew plan characteristics from more detailed space border of shared housing. Therefore, The basic framework of the characteristics spin for the cases that newly emerge later on.

Recently 3D GIS and its applications are getting attention increasingly as various ubiquitous-related techniques for 3D spaces are being developed. Although they call for quantitative measures such as accessibility, most accessibilityrelated studies are limited to 2D networks, not 3D indoor space levels. In this paper, we develop an accessibility index applicable to 3D models. We first examine the theory of Space Syntax which has been developed and used to measure the connectivity or relationships between spatial segments in urban or architectural environments. Then, we expand the principle to a more general form so it can be applied to both street and indoor space levels. We incorporate different types of impedances in moving between places including distances, turns and transfers between floors into the traditional Space Syntax that measures the spatial depths solely based on the structural forms. Finally, we illustrate the use of the proposed measure comparatively using a campus building.

Industrial paradigm change and awareness change based on development of transportation and communication technology, many idle facilities had been occurred. These idle facilities become the factor which hinder image and environment of the surroundings. In recent years, social, cultural and economic value of idle facilities has been acknowledged and is regarded as an object of rehabilitation as part of urban problem solving. The purpose of this study is to analyze the characteristics of recycling design in the exhibition space used as a domestic idle facility and to utilize it as a basic data for creating an exhibition space using idle facilities in the future. The scope of the study was selected from 8 cases which were reproduced as exhibition space within the last 10 years mainly in Seoul and metropolitan area. It is analyzed by five characteristics of historicity, symbolism, preservability, connectivity, and placeness that are analyzed by the characteristics of rehabilitaion design. The conclusion is as follows. First, idle facilities can be divided into idle industrial facilities and idle non - industrial facilities. Second, the analysis of the characteristics of rehabilitaion design of idle facilities showed that the symbolism was much higher than other rehabilitaion design characteristics. Third, as a result of comparative analysis between idle industrial facility exhibition space and idle non - industrial facility exhibition space, historicity, preservability, and connectivity were high in the idle industrial facility exhibition space. In the exhibition space of idle non-industrial facilities, symbolism and placeness were high.
