The purpose of this study is to propose and verify a spatial network construction method that integrated roads and subway lines to improve the predictability of the urban spatial analysis model. The existing axial map for urban spatial analysis did not reflect the subway line that serves as an important moving space in modern cities. To improve this axial map, proposed a Ground-Underground Spatial Network by integrating the underground spatial network with the axial map. As a result of the integration analysis, the Ground-Underground Spatial Network(GUSN) were similar to the movement frequency. Correlation of GUSN was 0.723, which showed higher explanatory power than correlation coefficient of 0.575 in axial map. The result of this study is expected to be a theoretical basis for constructing spatial network in urban space analysis with subway.

Modern cities are exposed to various dangers due to advanced technologies and advanced technologies. As a result, the desire for citizen's safety is increasing day by day, and the sense of insecurity is reaching extreme. In order to respond to the paradigm of the era for safety, the government has stipulated that crisis management manuals are prepared and operated according to the type of disaster. In this research, before preparing and managing crisis management manuals, we classify the types of disasters that can occur in A local authority, establish priorities of types of disasters to be managed with priority, We will try to utilize it as a basic material for the creation and management of.

Due to the recent overpopulation of urban cities, land shortage and soaring land prices have caused an increase in the demand for high-rise buildings. To build buildings on a limited land, the size of the building is important. Displacement control by horizontal loads in a skyscraper is critical to securing stability and usability of structures. Several systems have been proposed for efficient horizontal displacement control, and so far the study continues. Among them, the Outrigger System is a representative of the typical horizontal load resistance system. Although studies have been conducted so far to locate the optimal position of the outrigger, studies of the slenderness ratio of the buildings are still insufficient. Based on the Outrigger-Optimized Position equation, this study induces the calculation of the displacement of the outrigger installation building according to the slenderness ratio.

Bang walls surround the four sides of Band in ancient capital cities of East Asia where the Bang system was in operation. There are ongoing research efforts for the structure of a capital city and Bang system around the capital of Silla, but there is a huge shortage of research on Bang walls. This study thus set out to examine Bang walls in the capital of Silla around the Hwangnyongsa Temple and its surroundings. The findings show that the Bang walls in the capital of Silla were built with a mix of earth and stone and with tiled roofs on top. The sizes of Bang walls were distinguished from the walls of individual structure groups inside Bang and closely related to the Bang size and the width of adjacent roads.

Waste management in Jeju Province, Korea, has recently emerged as an urgent problem. The increasing waste discharge requires more landfills but, since it is an island, the available land is restricted. Accordingly, an efficient waste management urgently requires environmentally sustainable policies. In this article, the waste discharge characteristics (such as the amount of waste, its composition, etc.) of Jeju Province have been compared with those in the rest of Korea. The current industrial waste management of two cities on the Island, Jeju City and Seogwipo City, has been also analyzed to suggest policies for an efficient management. The local government's endeavor to enhance environmental awareness of the community has been known to reduce the private cost of policy compliance, and have individuals recognize the results of their policy compliance. Policies to achieve the above are then proposed.

In recent years, the planning of livable communities has emerged as a new paradigm. The concept of livable communities is related to both the spatial balance of working, playing, and living and the promotion of green modes of transportation, such as walking and biking. This study uses a disaggregate travel survey conducted by the Seoul Metropolitan Area in 2006. I applied a multi-level random intercept logit model to estimate the effects of land-use characteristics on the choice of green modes, holding a traveler's socio-demographic characteristics constant. The empirical results show that higher density and more mixed land-use development encourages people to walk and bike even when individuals have the same socio-economic characteristics. This paper demonstrates that land-use planning by itself can play a role in the creation of livable cities and the decline of greenhouse gas production.

The paper reports the result of a 2-year long research conducted by CTBUH on the design possibilities enabled by the Ropeless and Multidirectional elevator systems, investigating how such a significant innovation (or better to say revolution) in the vertical transportation could affect tall buildings first and cities then. The purpose of the study is to prefigure the adoption of ropeless and multidirectional cabins for tall buildings mobility, with the aim to overcome the evolutionary bottleneck of the high-rise building type due to the exclusively vertical direction of transport, which limited, over the years, the design possibilities in terms of height, shape and relations with the surrounding environment. CTBUH research team, together with professionals in the field and supporting academic advisors, developed a series of design considerations on plan organizations, dispatching alternatives and on the integration of horizontal direction in the circulation, with the aim of anticipating potential and criticality arising from the application of ropeless and multidirectional systems.

This preliminary study examines historical background of construction, establishment process, and destroy process for the Goryeo-sa-haeng-guan in Myeong-Ju during the Song Dynasty. The research was conducted based on local journals at that time. The Myeong-Ju is one of the famous port cities for marine trade. The Myeong-Ju had a good relationship with the Goryeo. Especially, the Song Dynasty built the Goryo-sa-haeng-guan for Goryeo envoys and traders to maintained a good partnership with Goryeo. A comprehensive review on records and historical issues of the Goryeo-sa-haeng-guan helps us to understand foreign policy and inter-relationship between Korean and China.

This study aims to test the relationship between the change in population size and population composition and crime changes. The analytical model includes variables representing changes in population size and population composition, three dependent variables for crime changes, and three control variables. Changes in popuvpdllation size and population composition are measured by indicators such as population size, gender, age groups, and immigrants and foreign workers, and crime changes by felonious, burglary, and violent crime volumes. The sample includes 154 cities and counties in South Korea, and the sample period is from 2010 to 2017. As a result of the analysis, I examine that the decrease in the number of young and men are likely to lead to a decline in felonious and violent crimes, but a high rate of the elderly and the increasing racial heterogeneity are likely to accelerate the fear and worries about crimes.

In Harbin, a network of underground commercial spaces has been developed to occupy spaces that were originally created as civil defense shelters. With the gradual extension of the local metro rail system, the existing underground commercial space is no longer an isolated regional development, but a space that represents "three-dimensional city" and coordinated development taking place in many Chinese cities. Based on the analysis of the unique development process taken in underground space of Harbin, this paper summarizes three characteristics of its early model of "fragmented development" of underground space. By conducting a comprehensive field research and survey, the researchers analyzed 472 questionnaires related to the development trend, and proposed multi-level synergistic elements for the renewal and development of underground commercial space. The paper concludes by discussing the trend of "three-dimensional and collaborative development," suitable for the development needs of the new era, and the corresponding development strategies for the renewal of underground space.
