  • As a part of the Smart Cities Mission, the Government of India in 2015 embarked upon the development of 100 existing cities as smart cities. In this study, the authors selected Ahmedabad city as the smart city development in India and presented project-level elements of the city based on the secondary data availability. At first, the authors focused on peer-reviewed articles, policy documents, and technical reports. Next, the authors collected the secondary data of project-level elements of the Ahmedabad city from the years 2015 to 2019. The findings show no significant improvement in the sewage system and waste collection as compared to the level of investment made in these sectors. The study showed that the water supply system outperformed revenue generation based on the government investment made in that sector. As a lesson learned, these findings indicate that significant improvement should be addressed in sewage management and waste collection. These study findings could help government officials, investors, developers, and city planners in making the appropriate decision before and during smart city execution. The lesson learned from this study could be used as a reference to improve revenue during the future smart city implication.

  • The world's population reached 7.7 billion in 2019. Despite this trend, not all cities are growing. Most of the growing population is driven to large cities for convenience and jobs. This phenomenon has led to a decrease in the population of small and medium-sized cities, and in certain cities, a decrease in employment as well as recession have resulted. Korea is no exception. The nation's population is concentrated in the metropolitan cities. To solve these problems, researchers started to study how to deal with the contraction of a city, i.e., a shrinking city, rather than focusing on only the growth of a city. In this paper, demographically outstanding declined domestic cities were selected as shrinking cities and their characteristics were analyzed. The concept of smart shrinking cities was then defined for the selected cities, which were chosen as a good case in overseas countries to solve the shrinking city problem. Through this process, the strategic differences were compared between domestic and oversea cases. As a result, a modified strategy for the smart shrinking city concept, FSSC (flexible smart shrinking city), is proposed as an alternative strategy that can save resources and cost.

  • Smart City is the regional innovation platform that actively utilizes information and communication technologies to diversify city services and improve the performance and quality, hence improving the quality of life and creating new trends of urban activities. Recently, the importance of citizen participation is increasingly emphasized to build smart cities successfully and the Living Lab, an open innovation platform led by users, is taking center stage as a means of realizing it. Accordingly, this study aims to establish the plans for popularizing living labs that provide innovative environments for domestic smart cities. To this end, first of all, political trends related to domestic smart cities' living labs were analyzed, and then, individual characteristics and development processes of the relevant cases were investigated. In addition, in-depth interviews were conducted with the experts of specialized agencies from Netherlands, Finland, and Denmark, etc. which are considered as leading countries in smart cities' living labs. As a result, in order to popularize living labs in domestic smart cities, the following policies were proposed; establishing support systems for commercialization and dissemination, building intermediary support organizations, improvement of laws and institutions, establishing the joint response systems with neighboring areas, etc.

  • Various smart city projects have been actively promoted as important policies of governments in various countries. The key to the success of smart cities led by governments is to develop sustainable governance through the expansion and proliferation of outcomes. This study comparatively analyzed the smart city policies of the USA and Europe from viewpoints of outcome expansion and proposed policy directions for smart cities in Korea. The comparison items were case cities, the expansion of smart city technologies and services, the measurement of outcomes, the accumulation of knowledge and information, and standardization. This study found that the items of each index were linked for the purpose of assessment, expansion, and the creation of successful cases in the USA and Europe. Based on our analysis, four policy directions were proposed that included the early provision of follow-up measures for case cities, the development of a project performance assessment system, the provision of an integrated knowledge accumulation system, and an earnest promotion of industry activation policies.

  • The article discusses the features of adaptation of the parameters of the physical layer of data transmission in self-organizing networks based on unmanned aerial vehicles operating in the conditions of "smart cities". The concept of cities of this type is defined, the historical path of formation, the current state and prospects for further development in the aspect of transition to "smart cities" of the third generation are shown. Cities of this type are aimed at providing more comfortable and safe living conditions for citizens and autonomous automated work of all components of the urban economy. The perspective of the development of urban mobile automated technical means of infocommunications is shown, one of the leading directions of which is the creation and active use of wireless self-organizing networks based on unmanned aerial vehicles. The advantages of using small-sized unmanned aerial vehicles for organizing networks of this type are considered, as well as the range of tasks to be solved in the conditions of modern "smart cities". It is shown that for the transition to self-organizing networks in the conditions of "smart cities" of the third generation, it is necessary to ensure the adaptation of various levels of OSI network models to dynamically changing operating conditions, which is especially important for the physical layer. To maintain an acceptable level of the value of the bit error probability when transmitting command and telemetry data, it is proposed to adaptively change the coding rate depending on the signal-to-noise ratio at the receiver input (or on the number of channel decoder errors), and when transmitting payload data, it is also proposed to adaptively change the coding rate together with the choice of modulation methods that differ in energy and spectral efficiency. As options for the practical implementation of these solutions, it is proposed to use an approach based on the principles of neuro-fuzzy control, for which examples of determining the boundaries of theoretically achievable efficiency are given.

  • The government has recognized the importance of smart city indicators and prepared the legal grounds for the certification of smart cities in the recently revised "Act on Smart City Development and Industrial Promotion." This study derived smart city indicators adequate for the domestic conditions and compatible with the overseas trends by examining and complementing the indicators through an AHP analysis based on consultations and interviews (surveys) with experts and local government officials, who are actually carrying out related projects. In addition, the adequacy and reliability of the indicators were confirmed by verifying and certifying the Korean local governments' smart city plans through demand surveys on a trial basis. This study is meaningful in that it systematically studies the smart city indicators that have gained in importance and reviews their application. The findings of this study can be used as a basis for implementing a smart cities certification system in the future. Recently, the Special Committee on Smart Cities was established under the Committee for the Fourth Industrial Revolution. This committee is composed of civilian members and is working with the Ministry of Land, Infrastructure, and Transport, the Ministry of Science and ICT, etc., to promote the creation of smart cities. It is expected that smart city indicators that include the levels of both domestic and overseas smart cities will boost the active spread of such cities in Korea.

  • We intend to improve the sustainability of rural villages by investigating the element technologies and platforms necessary for building smart villages. There are so many investment smart city platforms and solutions in many cities. but there are relatively few investments in rural or small cities. This situation can not only increase the urban problem due to the increase of population to the city, but also deepen the digital gap of citizens. So far, studies on smart village have been investigated in fragments. We will examine the cases applied to smart village as a whole and study the open smart village platform that analyzes the overall data storage and management of the village after the smart village was finally established. First, we will look at the overseas trends of smart village and second, we will study the smart village platform that efficiently manages smart village through the technology necessary for smart village.
