The purpose of this paper is to review relationship between spatial characteristics of compact city and urban sustainabiliy from system dynamics perspective using causal loop analysis. It has been argued that spatial characteristics of compact city, high population density and mixed land use, are positively related to urban sustainability. However, research results that are not consistent with pros of compact city argument have been accumulated too. It is especially true when spatial characteristics of compact city are examined with regard to each dimension of sustainablility: economic, social, and environmental sustainability. Reviewing each dimension of sustainability with regard to spatial characteristics based on causal loop analysis, this paper provides more clear understanding on relationship between compact city and sustainability. Also this paper provides a base for system dynamics simulation for future study.

ESCP Project showed an urban excavation case and introduced design method for case of Soil-Structure behavior in urban excavation. In this case, a retaining structures design to analysis the behavior of retaining wall and adjacent structures in urban excavations was applied by using a Elasto-plastic beam and limit Equilibrium analysis and soil-structure interaction analysis. Reliable design of earth retaining structures and the ground adjacent to braced wall in urban excavation are often difficult due to many variable factors. The ground settlement and the damage of adjacent structures in urban excavation has been an imprtant issue. Therefore, the stability of the adjacent structures must be secured with the excavation support and research on the protection of adjacent structure is necessary.

본 연구는 영암·해남 관광레저형 기업도시 솔라시도를 대상으로, 정원도시 구현을 위한 신도시 개발 개념을 제시하고 계획 전략을 수립한 연구이다. 본 연구는 먼저, 도시에서 정원의 개념을 땅의 가치를 존중하면서 도시의 자원으로 활용하는 과정적 차원으로 확장하고, 이를 바탕으로 솔라시도에서 정원도시의 의미를 "도시 조성의 태도와 과정", "도시구축체계", "도시슬로건"이라는 세 차원에서 각각 "도시를 만드는 틀로서 정원의 개념과 정신을 차용하는 도시", "오픈스페이스 네트워크가 곧 도시 구조의 기반이 되는 도시", "경관을 통해 정원도시의 상징성을 드러내는 도시"로 제시하였다. 나아가, 도시 축의 설정, 축의 결합과 망의 조성, 오픈스페이스 위계와 체계 구성이라는 공원녹지체계의 기본방향을 설정함으로써, 각 차원에 대한 구체적인 정원도시 구현 전략과 개별공간 설계안을 도출하였다. 본 연구는 신도시 개발의 대안적 모델로서 정원도시의 개념을 확장하고, 대상지의 고유한 경관적 가치를 계획 전략으로 활용했다는 점에서 의의가 있다. 또한, 정원도시 개발 컨셉을 통해 관광레저형 기업도시의 경관계획과 공원녹지체계를 제시했다는 점 역시 의의가 있다.

1960년대 이후 국내의 도심은 수도권 중심의 개발로 인한 집중화, 과밀화, 기반시설의 노후화 및 상업 기능의 쇠퇴 등 사회, 경제, 환경적 문제들이 발생하였으며, 2000년대 들어 각종 도시 문제를 해결하기 위해 도시재생사업이 대두되었다. 그러나 현재 도시재생사업은 다양한 용도의 복합화 시설을 추구하고 있으며 사업의 특성상 다수의 참여주체, 사업의 장기화 등으로 인해 업무 프로세스가 복잡해지고 있다. 이런 현상으로 수행업무가 체계화되지 못해 사업 참여자들은 사업을 진행하는 데 있어 참여자간의 복잡한 이해관계, 업무협업 등의 어려움을 겪고 있다. 이러한 문제점을 해결하기 위해 여러 기관에서 도시재생사업 관련 정보 시스템을 제공하고 있지만 사업 세부내용을 체계적으로 제공하는데 한계가 있다. 이에 본 연구에서는 도시재생사업의 현황 및 업무프로세스를 분석하고 업무정보관리의 체계성의 필요성을 제시하였다. 또한 도시재생사업 업무정보 체계 정립을 위해 BPS(Business Process Breakdown Structure, 이하 BPS)의 개념을 도입하여 사업진행을 위한 업무 정보를 분류하고 체계화 하였다. 이를 토대로 BPS기반의 도시재생사업 업무정보 시스템을 구현하고 시스템의 사용성을 평가하였다. 본 연구를 통해 BPS기반의 도시재생사업 업무정보 시스템을 구축함으로써 사업 참여자들에게 체계적인 도시재생사업관련 업무정보를 제공하여 효과적인 사업을 진행하는데 도움을 줄 것이다.

Urban space expansion is an important symbol of the urbanization process and has always been an important topic in urban studies. In addition, for sustainable city management, it is important to identify factors that can influence, such as the driving force and direction of urban space expansion, from the stage of establishing an urban development plan. To understand these factors, by observing the expansion process of a specific city, it is possible to sufficiently observe how the urban spatial dimension changes. Through a series of processes, the spatial growth characteristics of the city are analyzed, and the influence and results of important factors are analyzed. For this purpose, this paper examines the changes in the city's outer boundary and land use structure through monitoring data on urban areas of 14 cities in Hunan Province, China from 2000 to 2016. Temporal and spatial regularity according to the urban space expansion of these cities were analyzed, and a preliminary assessment was made on whether the urban space expansion is coordinated with the urban population growth. The assessment result showed: (1) The urban space of most cities has been extended rapidly in 2000-2015 however, the rate and the intensity of urban space expanding has been declining. (2) The construction of the industrial park is the core driving force of the urban space expanding, and the change of the urban space structure is manifested as enclave city expansion because that the industrial park is usually far away from the city center. (3) The population agglomeration is another driving force of the urban space expanding. At this time, the urban space expanding is like boundary extension. (4) Except Changsha city, all of the cities has a high urbanization-area-growth elastic coefficient. It means that most of the cities should enhance the land use degree.

The growth of online market is accelerating due to the development of technology and the era of pandemic. In order to deliver the ordered product to customers courier service should be used. In addition, the courier logistics market is growing with the growth of the online market. With the growth of the logistics market, traffic and environmental problems are emerging as social issues. Logistics technology of urban community logistics courier terminal system utilizing vacant space in the city has been developed as a new alternative to environment and traffic problems by increasing logistics efficiency in the city area. In this study, we propose a concept of a system that performs operational concept definition and scenario analysis by applying model-based perspective analysis to urban community logistics courier terminal system under development. Through this study, we defined the operating concept of the urban community logistics courier terminal, which is the target of development, and defined the scenario for system operation by grasping the structure and function of the system and applied it to system development.

A 3D modeling of urban area can be composed the terrain modeling that can express specific and shape of the terrain and the object modeling such as buildings, trees and facilities which are found in urban areas. Especially in a 3D modeling of building, it is very important to make a unit model by simplifying 3D structure and to take a texture mapping, which can help visualize surface information. In this study, the texture mapping technique, based on library for 3D urban modeling, was used for building modeling. This technique applies the texture map in the form of library which is constructed as building types, and then take mapping to the 3D building frame. For effectively apply, this technique, we classified buildings automatically using LiDAR data and made 3D frame using LiDAR and digital map. To express the realistic building texture, we made the texture library using real building photograph.

Needs for underground space development and utilization have been increasing in urban area. The conventional strutting method in excavation is effective to restrain the ground movements and displacements of earth structures but inefficient for workers because of small working space. The conventional earth reinforcement methods such as earth-anchor and soil-nailing also have limitation to apply in urban area due to threats to stability of adjacent buildings around excavation boundaries. Recently, many types of earth retaining structures are being developed to overcome disadvantages of conventional excavation methods in urban area. In this study, a series of numerical analyses were performed with MIDAS GTS, geotechnical analysis program and MIDAS Civil, structural analysis design program to evaluate behavior and stability of the new type of non-supporting earth retaining structure, called Temporary Tower System (TTS), consisting of tower truss structures with much economical and spatial advantage.
