As urbanization and its consequences become the issue of modern cities, the concept of Smart City comes as the solution. Though a lot of researches on the topic is done, still no clear definition is given for both: Smart City itself and the factors of a successful Smart City. While most of the literature centers the role of ICT it is not a sufficient condition for a city to become Smart; the role of intellectual capital is underestimated. Using a collection of Smart City definitions across the time and providing concrete cases, this research seeks to bridge definition gaps and creates a tool for understanding Smart Cities. Drawing on the findings of several case studies, this research derives several explanatory factors. The citizen's engagement and governance are identified as the two key success factors of Smart City Projects along with ICT and other factors as enablers. The research has purpose as follows: 1) To bridge definition gaps of the "Smart City" by defining the term "Smart City," based on existing concepts and characteristic mechanisms across times.; 2) To develop an analytical tool for Smart City success factors through Explanatory Variables.; and 3) To identify major challenges and barriers of Smart City Projects implementations and to provide recommendations and solutions, based on existing governmental initiatives and pilot projects. The research contributes to the knowledge of smart cities and ICT integration for urbanization issues solution. By applying the findings of this research at the managerial level stakeholders may benefit by getting higher efficiency of the Smart City Projects and by utilizing knowledge and values of a Smart City Projects in a prioritized way.

This paper analyzes the existing transportation systems of Nigeria and Korea and proposes a new railway and roadway design for Nigerian cities. The research findings and feasibility study revealed that the state of Nigeria's transportation system was critical as was its market segment, infrastructural deficit and financial requirement needed to implement a smart transportation system. The dilapidation of the existing infrastructure coupled with poor maintenance culture and limited public transport services has hindered the economic growth of Nigeria and its cities. A case study of Korea and Japan shows some possible solutions to Nigeria transportation challenges. Analytical and descriptive methods were used to critically assess the infrastructural challenges, movement, and convenience. The study proposed the design of a new intercity railroad and roadway across Abuja, Enugu, Lagos and Port Harcourt cities. The proposed designs have been established to be an innovative solution with advanced benefits over the current system. The implementation of the proposed designs is estimated to cost about US$(77,832,027,719) across the study areas. Thus, the discussion, conclusion, and recommendations given present a proposal to the Nigerian government on the possibility of solving the Nigerian intercity railroad and roadway transportation challenges across Abuja, Enugu, Lagos and Port Harcourt cities through smart designs.

본 연구의 목적은 국내 주요 도시의 스마트시티 수준을 분석하는 것이다. 연구는 문헌고찰, 평가지표 구축, 평가지표 가중치 분석, 지자체 스마트시티 수준 분석, 결론의 순서로 진행되었다. 스마트시티 수준 분석을 위한 평가지표는 다층형 스마트시티 모델(Multi-Layered Smart City Model)의 STIM 구조(Service, Technology, Infrastructure, Management Layered Architecture)기반으로 구축되었다. 평가지표는 스마트시티 개념, 사례, 빅데이터 분석 등을 통해 구축되었고, 전문가 AHP 설문을 통해 가중치가 부여되었다. 연구의 공간 범위는 서울 등 7대 광역시이며, 시간 범위는 2017년~2019년이다. 연구에 사용된 데이터는 KOSIS, KISDISTAT 등의 공공데이터이다. 평가결과는 다음과 같다. 스마트시티 서비스, 기술, 인프라, 관리의 수준은 수도권인 서울과 인천이 비교적 높은 수준으로 분석되었다. 영남권인 부산, 대구, 울산이 비교적 중간 수준으로 분석되었으며 충남권과 호남권인 대전과 광주가 비교적 낮은 수준으로 분석되었다. STIM 종합순위 또한 비슷한 양상을 보인다. 특히 수도권과 그 외 권역의 스마트시티 수준 격차가 매우 큰 것으로 분석되었다. 국내 스마트시티 수준 격차를 줄이기 위해 균형발전 전략이 필요하며, 지역별 특성을 고려한 스마트시티 계획이 필요하다.

Recently, urbanization has become a serious issue, as there is imbalance between regions and various environmental problems occur intensively in cities. Therefore, cities all over the world are promoting the Green New Deal and trying to realize carbon neutrality. Accordingly, the European Union is leading the creation of carbon-neutral cities by promoting policies aimed at rapidly realizing carbon neutrality. In Korea, projects such as U-City and Smart City have also been promoted continuously for many years, and recently, the projects Smart Green City and Carbon Neutral Green City have been introduced. Therefore, this study aimed to derive directions and implications for future projects based on policies to address climate change by analyzing the guidelines for the Smart Green City project and the project plans of Gimhae-si and Gangjin-gun, which are the leading projects in the Smart Green City business model and are equipped with an extensive budget.

The deployment of 5G is in full swing, with a significant yearly growth in the data traffic expected to reach 26% by the year and data consumption to reach 122 EB per month by 2022 [10]. In parallel, the idea of smart cities has been implemented by various governments and private organizations. One of the main objectives of 5G deployment is to help develop and realize smart cities. 5G can support the enhanced data delivery requirements and the mass connection requirements of a smart city environment. However, for specific high-demanding applications like tactile Internet, transportation, and augmented reality, the cloud-based 5G infrastructure cannot deliver the required quality of services. We suggest using multi-access edge computing (MEC) technology for smart cities' environments to provide the necessary support. In cloud computing, the dependency on a central server for computation and storage adds extra cost in terms of higher latency. We present a few scenarios to demonstrate how the MEC, with its distributed architecture and closer proximity to the end nodes can significantly improve the quality of services by reducing the latency. This paper has surveyed the existing work in MEC for 5G and highlights various challenges and opportunities. Moreover, we propose a unique framework based on the use of MEC for 5G in a smart city environment. This framework works at multiple levels, where each level has its own defined functionalities. The proposed framework uses the MEC and introduces edge-sub levels to keep the computing infrastructure much closer to the end nodes.

이 연구에서는 국내 주요 도시들이 스마트시티 관련 기술을 활용하는 방식을 조사하여 도시의 스마트성과 효율성을 측정하기 위한 핵심성과지표(KPI)를 개발하고, DEA 분석을 통해 도시의 운영 효율성을 파악한 내용을 기반으로 스마트시티 정책 방향을 제안하는 방법론을 제시하고자 한다. CITYkeys의 스마트시티 성과측정 프레임워크를 참고하여 10개의 핵심성과지표(KPI)를 도출하였으며, 각 KPI마다 도시 통계데이터를 투입변수와 산출변수에 할당하고, 15개 도시들을 DMU에 할당하였다. DEA 방법론을 활용하여 도시의 효율성과 규모수익성을 평가하였다. 이를 통하여 도시의 운영효율성을 파악하였다. 최종적으로 각 DMU 간의 운영효율성을 순위화하여 도시별 스마트시티 정책 방향을 제안하였다.

Over the past two decades following the 1990s, South Korea's IT industry has developed rapidly. In keeping with this trend, the architectural and urban planning sectors have also converged with IT and achieved advancement in new directions. This evolution includes a variety of conceptual terminologies such as 'home automation', ''home network', 'smart home, and 'ubiquitous-city'. However, smart homes and U-cities simply represent a conceptual extension of home networks, and there is little real difference in the technologies involved. In particular, U-cities remain focused on infrastructure rather than on the development of specific content; consequently, they have failed to demonstrate distinctive features to clearly differentiate themselves from conventional cities. In such a context, this research aims at the proposal of a 'ubiquitous pavilion' as a component of the efforts to develop a range of architectural contents that utilize ubiquitous technologies. By grafting the pavilion, one of the most basic forms in architecture, with cutting-edge ubiquitous technologies, this paper intends to suggest a multi-purpose architectural space readily and simply available not only in newly emerging U-cities, but to conventional cities as well.

현대 도시는 다양한 도시 문제에 대응하기 위해 적극적으로 스마트시티 서비스를 도입하고 있다. 공간정보는 스마트시티의 기반 인프라로 작용하며, 도시의 지속 가능한 발전을 촉진한다. 공간정보의 표준화와 활용이 증가함에 따라 스마트시티의 효율적인 운영과 지속가능성이 향상되는데, 이를 위해서는 다양한 이해관계자들간의 협력을 통한 최적의 공간정보 기반 스마트시티 서비스 제공이 중요하다. 본 연구에서는 교통 및 건축-에너지 도메인 중심의 스마트시티 서비스를 공간정보 기술의 생애주기 기반으로 정의하고, 이를 공간정보 표준에 적용하고 활용하는 중요성을 강조한다. 또한, 공간정보 표준기반 스마트시티(SCGI, Smart City based on Geospatial Information standards) 프레임워크를 제안하여, 공간정보 표준에 매핑 가능한 스마트시티 서비스의 표준화에 관한 인사이트를 제시하였다. 본 연구는 공간정보 표준을 활용하여 커스터마이징된 솔루션을 제공함으로써 스마트시티 서비스의 표준화를 위한 새로운 패러다임을 제시하며, 스마트시티의 미래 발전 가능성을 논의한다.
