4차산업혁명 기술의 등장 및 발전과 함께 현대 도시는 스마트도시로 빠르게 변화하고 있다. 여러 4차산업혁명 기술 중 블록체인은 기술적 혁신성뿐 아니라 사회적 혁명성도 포함한다는 독특한 특성이 있다. 이 때문에 블록체인은 스마트도시가 종합적으로 발전하는 데 있어서 중요한 역할을 할 것으로 예상된다. 그러나 현재 우리나라에서 스마트도시와 관련된 블록체인 연구나 정책은 주로 기술적인 측면에 머물고 있으며 그 이상의 잠재력은 간과하고 있다. 본 연구는 스마트도시와 블록체인에 대한 종합적인 검토를 통해 블록체인 기술이 사회, 경제, 제도, 거버넌스 등 다양한 영역에서 스마트도시의 발전에 어떻게 이바지할 수 있는지 밝히는 것을 목표로 한다. 또한, 현재 각 영역에서 시범적으로 추진되고 있는 프로젝트들을 살펴볼 것이다. 연구 결과 국내에서는 신원인증, 물류, 지역화폐 등 다양한 영역에서 스마트도시에 블록체인을 적용하는 시도가 활발하게 일어나고 있지만 아직 이들 블록체인 프로젝트들은 개별로 추진되고 있을 뿐 스마트도시라는 공통된 영역에서 종합적으로 발전하는 단계까지 도달하지 못한 것으로 판단된다. 앞으로 블록체인이 스마트도시에 더욱 효과적으로 기여하기 위해 기업, 정부, 시민이 함께 블록체인의 지속가능성과 타 기술과의 융합에 대해 심도 있게 논의할 필요가 있다.

We see an energy fucused smart city evolution of the UK along with the project of "Smart London Plan (SLP)." A theoretical logic of business model innovation has been discussed and a research framework of evolving energy focused smart city is formulated. The starting point is the silo system. In the second stage, the private investment in smart meters establishes a basement for next stages. As results, the UK's smart energy sector has evolved from smart meter installation through smart grid to new business models such as water-energy nexus and microgrid. Before smart meter installation of the government, the electricity system was centralized. However, after consumer engagement plan has been set to make them understand benefits that they can secure through smart meters, the customer behavior has been changed. The data analytics firm enables greater understanding of consumer behavior and it helps energy industry to be smart via controlling, securing and using that data to improve the energy system. In the third stage, distribution network operators (DNOs)' access to smart meter data has been allowed and the segmentation starts. In the fourth stage, with collaboration of Ofwat and Ofgem, it is possible to eliminate unnecessary duplication of works and reduce interest conflict between water and electricity. In the fifth stage, smart meter and grid has been integrated as an "adaptive" system and a transition from DNO to DSO is accomplished for the integrated operation. Microgrid is a prototype for an "adaptive" smart grid. Previous steps enable London to accomplish a platform leadership to support the increasing electrification of the heating and transport sector and smart home.

These-days technology related to IoT (Internet of Thing) is widely used and there are many types of smart system based IoT like smart health, smart building and so on. In smart health system, it is possible to check someone's health by analyzing data from wearable IoT device like smart watch. Smart building system aims to collect data from sensor such as humidity, temperature, human counter like that and control the building for energy efficiency, security, safety and so forth. Furthermore, smart city system can comprise several smart systems like smart building, smart health, smart mobility, smart energy and etc. In this paper, we propose multimedia IoT based intelligent emergency alarm system for smart city. In existing IoT based smart system, it communicates lightweight data like text data. In the past, due to network's limitations lightweight IoT protocol was proposed for communicating data between things but now network technology develops, problem which is to communicate heavy data is solving. The proposed system obtains video from IP cameras/CCTVs, analyses the video by exploiting AI algorithm for detecting emergencies and prevents them which cause damage or death. If emergency is detected, the proposed system sends warning message that emergency may occur to people or agencies. We built prototype of the intelligent emergency alarm system based on MQTT and assured that the system detected dangerous situation and sent alarm messages. From the test results, it is expected that the system can prevent damages of people, nature and save human life from emergency.

This study examines Natal in Brazil as a Smart Tourism Destination (STD) based on the perception of public and private managers who are members of the City Tourism Council. The research utilizes a systemic perspective of STD proposed by Ivars-Baidal et al. (2016), consisting of three interconnected levels: Strategic-Relational, Instrumental, and Applied. The findings reveal that Natal faces challenges in terms of infrastructure, accessibility, security, connectivity, and sensoring, which hinder its progress as STD. The study also identifies opportunities in the form of governance structures with smart destinations and the inclusion of smartness guidelines in the City Master Plan. The research aims to contribute to the theoretical understanding of STD and its application in destination development. It highlights the need for innovative planning and management in Natal, emphasizing that adopting the STD from a systemic perspective can enhance competitiveness and elevate the level of smartness in the destination.

Purpose: To solve urban problems, empirical research is being actively conducted to implement a smart city based on various ICT technologies, and digital twin technology is needed to effectively implement a smart city. A digital twin is essential for the realization of a smart city. A digital twin is a virtual environment that intuitively visualizes multidimensional data in the real world based on 3D. Digital twin is implemented on the premise of the convergence of GIS and BIM, and in particular, a lot of time is invested in data pre-processing and labeling in the data construction process. In digital twin, data quality is prioritized for consistency with reality, but there is a limit to data inspection with the naked eye. Therefore, in order to improve the required time and quality of digital twin construction, it was attempted to detect a building using Mask R-CNN, a deep learning-based masking algorithm for aerial images. If the results of this study are advanced and used to build digital twin data, it is thought that a high-quality smart city can be realized.

Smart City is gaining attention with the advancement of Information and Communication Technology (ICT). ICT provides the basis for smart city foundation; enables us to interconnect all the actors of a smart city by supporting the provision of seamless ubiquitous services and Internet of Things. On the other hand, Crowdsourcing has the ability to enable citizens to participate in social and economic development of the city and share their contribution and knowledge while increasing their socio-economic welfare. This paper proposed a hybrid model which is a compound of human computation, machine computation and citizen crowds. This proposed hybrid model uses knowledge-based crowdsourcing that captures collaborative and collective intelligence from the citizen crowds to form democratic knowledge space, which provision solutions in areas of civic innovations. This paper also proposed knowledge-based crowdsourcing framework which manages knowledge activities in the form of human computation tasks and eliminates the complexity of human computation task creation, execution, refinement, quality control and manage knowledge space. The knowledge activities in the form of human computation tasks provide support to existing crowdsourcing system to align their task execution order optimally.
