This study aims to propose a smart city governance logic model that can accommodate more diverse information service systems by mixing hub-and-spoke and blockchain technologies as a data management model. Specifically, the research focuses on deriving the logic of an operating system that can work across smart city planning based on the two data governance technologies. The first step of the logic is the generation and collection of information, which is first divided into information that requires information protection and information that can be shared with the public, and the information that requires privacy is blockchainized, and the shared information is integrated and aggregated in a data hub. The next step is the processing and use of the information, which can actively use the blockchain technology, but for the information that can be shared other than the protected information, the governance logic is built in parallel with the hub-and-spoke type. Next is the logic of the distribution stage, where the key is to establish a service contact point between service providers and beneficiaries. Also, This study proposes the establishment of a one-to-one data exchange relationship between information providers, information consumers, and information processors. Finally, in order to expand and promote citizen participation opportunities through a reasonable compensation system in the operation of smart cities, we developed virtual currency as a local currency and designed an open operation logic of local virtual currency that can operate in the compensation dimension of information.

It only takes one failed project to wipe out an entire year's profit, when the projects are not managed efficiently. Additionally, escalating costs of materials and a competitive local construction market make subcontractors a challenge. Subcontractors have finite resources that should be allocated simultaneously across many projects in a dynamic manner. Significant scheduling problems are posed by concurrent multi-projects with limited resources. The objective of this thesis is to identify the effect of productivity changes on the total cost resulting from shifting crews across projects using a descriptive model. To effectively achieve the objective, this study has developed a descriptive cost model for a subcontractor with multi-resources and multi-projects. The model was designed for a subcontractor to use as a decision-making tool for resources allocation and scheduling. The model identified several factors affecting productivity. Moreover, when the model was tested using hypothetical data, it produced some effective combinations of resource allocation with associated total costs. Furthermore, a subcontractor minimizes total costs by balancing overtime costs, tardiness penalties, and incentive bonus, while satisfying available processing time constraints.

This study is to examine the public participation activities in the progress of the design competition, purposed to provide urban public spaces by the reuse of industrial heritages. Through the case studies of Berlin Tempelhof Parkland, Mapo Depot and Seoul Station 7017, following activities are common: citizen idea competition, forum, field trip, survey and winners exhibition. However, those activities are more closely organized to the competition process in Tempelhof Parkland, than other tow projects of Seoul Metropolitan Government. Also, it enables to clear and develop the public ideas more that those programs such as survey, citizen idea competition and field trip, are linked to each other in the case of Tempelhof Parkland. It could be achieved by the unified organization between competition preparation and public participation operation.

Design-build projects were devised to enhance the design technologies of the domestic construction industry and the efficiency of public works, contributing greatly to the development of construction technologies. However, as various stages of the process, such as formulation of basic plans and design documents, and deliberations proceed, claims, including changes in the requirements of clients, and design changes occur. These claims result in the delay in construction and an increase in construction costs. In this regard, this study attempted to identify main claims that delay construction and increase the costs of design-build projects, prevent claims in the future, and improve the efficiency of project implementation.

Urban planning involves many different disciplines. In order for the related stakeholders to have better understanding and acceptable outcomes, planners are required to present a methodology that would properly reflect people's interest. In order to justify the demand and distribute people's interest, planners actively utilized the suitability analysis. Accordingly, a suitability analysis to find the optimal route for high-speed rail was performed in this paper. With ArcGIS and geographic data sets, simple map algebra could be used. The final product of this research was a map indicating the suitable routes for high-speed rail using the shortest path analysis.

This study aims at finding issues and ideas of waterfront planning through analysing planning concepts and characteristics of New York City Waterfront Comprehensive Plan(NYC WCP). The first NYC WCP in 1992 divided waterfront area as 4 functional areas which are natural, public, working and redeveloping waterfront. The characteristics of WCP in 1992 are zonning, height, setback, public access, visual corridor, floor area and so forth. After then NYC WCP revision in 2011 intergrated and developed the former plan through the eight visions which are expanding public access, enlivening the waterfront, improving water quality, restoring the natural waterfront, enhancing the Blue Network, improving government oversight and increasing climate resillience. In conclusion, NYC WCP successfully achieved both sufficient capacity of planning concepts and design guidelines for each region.

Cities have complex system composed diverse activities. The activities in cities have complex relationship that creates diverse urban phenomena. Big Data is emerging technology in order to understand such complex network. This research aims to understand such relations by analysing the diverse city indexes. 28 indexes were collected in 25 of districts in Seoul city and analysed to find a weighted correlation. By defining the correlation values of certain years, it tries to predict the missed index values, "happiness" of each districts in other years. The result presents that the overall prediction accuracy 70.25%. However, for further discussion, the result is considered that this methods may not enough to use in practice, since the data has inconstant accuracy by different learning years.

In this paper, we construct a prototype model for city data prediction by using time series data of floating population, and use machine learning to analyze urban data of complex structure. A correlation prediction model was constructed using three of the 10 data (total flow population, male flow population, and Monday flow population), and the result was compared with the actual data. The results of the accuracy were evaluated. The results of this study show that the predicted model of the floating population predicts the correlation between the predicted floating population and the current state of commerce. It is expected that it will help efficient and objective design in the planning stages of architecture, landscape, and urban areas such as tree environment design and layout of trails. Also, it is expected that the dynamic population prediction using multivariate time series data and collected location data will be able to perform integrated simulation with time series data of various fields.

After Landscape Act was enacted, as awareness of landscape has increased and the need of expanding targets of landscape design review and improving landscape examination in terms of quality, this study aims to describe a technique of creating three dimensional landscape simulation model which is used for landscape design review. For this, the author of this study conducted analysis in terms of function and use of programs and compatibility with programs to find a way of creating models with the most efficient and optimum process. For creation of landscape simulation models, initial creation is important but in case that changes occur by operator changing or discussing development plans, rapid correction and change are needed. Therefore, this study described how to build more accrurate and efficient simulation at initial review and how to create a landscape simulation model for rapid response to changed plans during reconsideration.
