The first generation of Japan's smart city policies began around 2010. However, the latest trends in smart city policies and the impacts of the first generation on the latter one were not fully covered in either official documents or academic literature. In such circumstances, the purposes of this study were firstly to identify outcomes derived from the smart city projects in the first generation, and then, to reveal the present situation of the latest smart city policies, including the influence of the first generation on these state of the art policies. The present study was also intended to evaluate the validity of a conceptual framework presented by Fernandez-Anez et al. (2018) for smart city policies. As a result, it was revealed that (1) policy outputs and outcomes derived from the smart city policies in the first generation were highly regarded, (2) the conceptual framework of smart city policies was evaluated as valid, and (3) the second generation of smart city policies after Society 5.0 was characterized by the establishment of smart city platforms.

In order to respond dynamic changes in the global distribution system, the City of Pyeongtaek hope to expand port facilities and its hinterlands. In specific, it plans to designate these areas as free economic zones(FEZ), synthesizing the whole procedures from the development proposals to the operation and management. This paper examines the proposed urban development strategies focused on Pyeongtaek port which still reveals critical weakness as a gateway port backed up by the Seoul Metropolitan Areas. In order to enhance the global competitiveness of Pyeongtaek port, theoretically it depends on Geo Coyle's ACTIFELD methods. In addition to the traditional quantitative data, Coyle's ACTIFELD methods emphasize qualitative approaches, all of which would facilitate structural and systemic analyses of complex social phenomena. Applying ACTIFELD methods, this paper proposes that the City of Pyeongtaek should focus on three alternatives. That is, Pyeongtaek's policy priority should be given to ts he port city based on the key concepts of Supply Chain Management(SCM), Co-opetition supporting city, and waterfront-initiated urban development.

The goal of this study is to suggest policy tasks for the public library in Seoul. For this goal, researcher compared macroscopically the gap between the Seoul city and the global competitiveness city using the core index of the public library, and analyzed microscopically the level of the Seoul city and the metropolitan cities and provinces focusing on the public library infrastructure and service index. Next, researcher evaluated the public library policies by linking the "2030 Seoul City Master Plan" and the "Library and Reading Culture Revitalization Plan". Based on the results, researcher proposed branding for global knowledge culture capitals, advancement of core competencies and systems of libraries, composition of citizen centered knowledge culture ecosystem, maximization of citizen's service satisfaction and expected benefits as future-oriented policy tasks of public libraries in Seoul.

This study aims to evaluate the effectiveness of sterilization in Vietnam. We estimate a simultaneous equation by using Two-Stage least squares (2SLS) regression analysis. The time-series data was collected for the first quarter of 2004 to the fourth quarter of 2018. In particular, the effectiveness of sterilization is considered in terms of dollarized economy, since making the transition from a centrally planned to a market economy system, the Vietnamese economy has remained in a state of dollarization. In addition, we also assess whether the global financial crisis had an impact on the sterilization effectiveness of the State Bank of Vietnam (SBV). On the basis of the estimated sterilization and offset coefficients, our results suggest that the State Bank of Vietnam (SBV) has not been able to fully neutralize the impact on the domestic money supply when intervening in the foreign exchange market, and the capital inflows respond strongly to changes in domestic monetary conditions. The results also show that the global financial crisis has changed the effectiveness of these sterilization policies. An analysis of this study's empirical findings provides the opportunity to derive some recommendations that may assist in increasing the effectiveness of the State Bank of Vietnam's sterilization policies in the process of accumulating international reserves.

In this study, a new seismic retrofit scheme of building structures is developed by combining a steel moment frame and steel slit plates to be installed inside of an existing reinforced concrete frame. This device has the energy dissipation capability of slit dampers with slight loss of stiffness compared to the conventional steel frame reinforcement method. In order to investigate the seismic performance of the retrofit system, it was installed inside of a reinforced concrete frame and tested under cyclic loading. Finite element analysis was carried out for validation of the test results, and it was observed that the analysis and the test results match well. An analytical model was developed to apply the retrofit system to a commercial software to be used for seismic retrofit design of an example structure. The effectiveness of the retrofit scheme was investigated through nonlinear time-history response analysis (NLTHA). The cyclic loading test showed that the steel frame with slit dampers provides significant increase in strength and ductility to the bare structure. According to the analysis results of a case study building, the proposed system turned out to be effective in decreasing the seismic response of the model structure below the given target limit state.

This study aimed to develop a seismic retrofit technique using a steel frame which can be easily transported and assembled on site. This enables the retrofit steel frame to be easily attached to an existing structure minimizing the unwanted gap between the structure and the steel frame assembly. A one-story one-bay RC frame was tested with and without seismic retrofit using the proposed steel frame to verify the seismic retrofit effect of the proposed system, and an analysis model was developed in Opensees for seismic performance evaluation of a case study soft first-story model structure retrofitted with the developed steel frame assembly. Seismic performance of the model structure was also evaluated considering soil structure interaction effect. The experimental study confirmed that the proposed seismic retrofit system can be applied effectively to improve the seismic performance of framed structures. Time history analysis results of the model structure showed that the proposed steel frame assembly was effective in increasing the seismic load resisting capacity of the soft first-story structure. However more steel frame assemblies were required to satisfy the given performance limit state of the model structure located on weak soil due to the negative soil-structure interaction effect.

Since the industrial revolution, the global environmental problems such as greenhouse gas accumulation and the average temperature increase have caused people's attention. 'Low Carbon, Green Growth' was presented to cope with these global concerns, as one of main policies of 2008 in Korea. The paradigm of a green urban development is started to concern the whole city's energy problems owing to realize 'Low Carbon, Green Growth' in the urban side. The government established a nation's basic energy plan for 20 years, and some local cities made efforts to develop new renewable energy such as the solar, wind and water energy which are suitable to each city's character. As a part of these efforts, the concept of U-Eco city is newly appeared to reflect upon ubiquitous technique, urban ecology and the next generation energy system. However, urban plan is difficult to adopt this next generation energy system with existing laws, regulations and technical systems. The new executive and systematic system is needed to realize the U-Eco city U-Eco for the management of an efficient city. In this study, the authors investigate the concept of the next generation energy system and U-Eco city to realize the energy-efficient city plan and analyze problems to occur during the application of them in an existing city plan. Then, the authors show the remedies to deal with occurred problems.
