부산 에코델타시티는 세종 5-1 생활권과 더불어 스마트시티 국가시범도시이며, 사업대상지역은 평강천이 관류하여 맥도강, 서낙동강 본류로 흐르는 세물머리지역이 그 중심에 위치하고 있다. 하천을 중심으로 스마트시티가 조성되고 있으나 하천관리는 유역내 홍수관리, 수질관리 등등에 관한 정부주체 상위계획에 종속성이 강한 공공분야로서 단위사업에서 스마트시티에 걸맞는 하천관리계획을 수립하고 시행하는 것은 많은 어려움이 존재한다. 하천관리의 주 관심 대상은 이수를 제외하면 치수, 하천환경, 친수, 하천시설물로 대별할 수 있으며, 스마트 하천관리란 이들에 대한 현황 정보구축 및 지속적인 현행화, 그리고 이들 실제 정보를 토대로 한 합리적 운영과 실시간 연계운영 실현으로 공공서비스를 제공하는 것이라 할 수 있을 것이다. 본 연구는 국가연구개발사업에서 연구한 각 분야별 하천관리기법을 에코델타시티에 시범적용하여 스마트하천관리를 구현할 수 있는 방법을 제시하고자 하였다. 에코델타시티 조성사업의 진행수준으로 인해 취득하기 어려운 정보들은 수립된 계획을 참조하여 적용하였다. 유역내 주 대상 하천들은 델타지역에서 수문으로 통제되므로 일반적인 하천과 달리 정수역에 가까운 특이한 수리특성을 보이고 있지만, 우선 스마트 하천관리를 위한 일반적인 과정들을 시범적용 해보고 필요에 따라 특성 고려 방안을 찾고자 하였다. 유역내 정량적 홍수위험도 평가, 하천환경 평가 적용방안, 하천시설물 관리방안, 주요 지점의 실시간 모니터링 방안 등이 에코델타시티 조성사업 진행단계를 고려하여 수행되고 있다. 사용편의성과 지속가능성을 담보하기 위한 하천연계플랫폼을 구축하여, 개발된 기법들을 각각 내부 모듈로 장착하거나 완성도에 따라 외부모듈로 연계할 수 있도록 하였다. 현재 개발된 기법들의 시스템화 완성 및 관련 정보들의 데이터베이스 확대를 위한 노력이 진행되고 있으며, 향후 하천관리연계플랫폼의 실제 운영을 통하여 완성도를 높여갈 계획이다.

This study aims to present the direction of development of a policy framework to solve the problems associated with Smart Cities. For this purpose, first, after investigating the development process of domestic smart cities, we examined various cases of smart city policies being established overseas. Second, we analyzed the existing research into smart cities, in order to understand the relationship between the major issues. Third, an expert interview was conducted based on the identified issues. Fourth, we presented the direction of development of a Smart City policy framework to solve the major problems associated with domestic and foreign smart cities. In the policy framework presented in this research, after subdividing the elements used for solving each problem, we linked them with the smart city components and selected matching executable agents to prepare solutions. Then, once the deliberation process of the National Smart City Committee and the Smart Urban Service Support Organization has been completed, the government will support it financially and politically. It also suggested that it is necessary to perform continuous information gathering and monitoring work, along with the construction of a control tower to strengthen the network effect between smart city related markets. This research has significance in that it presents the procedures required for efficiently responding to the problems arising in the smart city promotion process. It is expected that it will serve as the basis for establishing policies dealing with the development and advancement of domestic smart cities in the future.

Global warming is accelerating as greenhouse gas emissions increase owing to the increase in population and urbanization rates worldwide. As an alternative to this solution, smart cities are being promoted. The purpose of this paper is to suggest a plan for developing energy service modules for the Sejong 5-1 living area, which has been selected as a test-bed for smart cities in Korea. Based on the smart city plans announced by the government for this study, a survey questionnaire on 12 energy services was composed by collecting the opinions of experts. The survey was conducted with 1,000 citizens, the degree of necessity of energy service that citizens think of was identified. Principal Component Analysis and Association Rule Mining were conducted to describe 12 energy service items in a reduced manner and analyze the correlation and relationship of each energy service. Finally, three modules were suggested using the analyzed results so that 12 energy services could be implemented in an efficient platform. These results are expected to contribute to the realization of a smart city to make them easily accessible for those who want to promote platform services in the energy field and envision energy service items.

Smart Cities intelligently manage numerous infrastructures, including Smart-City IoT devices, and provide a variety of smart-city applications to citizen. In order to provide various information needed for smart-city applications, Smart Cities require a function to intelligently process large-scale streamed big data that are constantly generated from a large number of IoT devices. To provide smart services in Smart-City, the Smart-City Consortium uses stream reasoning. Our stream reasoning requires real-time processing of big data. However, there are limitations associated with real-time processing of large-scale streamed big data in Smart Cities. In this paper, we introduce one of our researches on cloud computing based real-time distributed-parallel-processing to be used in stream-reasoning of IoT big data in Smart Cities. The Smart-City Consortium introduced its previously developed smart-city middleware. In the research for this paper, we made cloud computing based real-time distributed-parallel-processing available in the cloud computing platform of the smart-city middleware developed in the previous research, so that we can perform real-time distributed-parallel-processing with them. This paper introduces a real-time distributed-parallel-processing method and system for stream reasoning with IoT big data transmitted from various sensors of Smart Cities and evaluate the performance of real-time distributed-parallel-processing of the system where the method is implemented.

Because the 'Internet of Things' and sensor network technology have become a new generation industry competitiveness with a development of Information Communication Technology, each local autonomous entity is trying to adopt a Smart City quickly. This requires an integrated platform inside of a smart city operation center. Established Smart City platform provides various services using CCTV information and ITS transportation information based on a two-dimensional map. The provision of advanced Smart City services will necessitate three-dimensional map information, building and facilities unit information, linked information with public data portal for service to the public. In this paper, the authors reviewed development trends of Smart City integrated platform and proposed mashup methods between BIM/GIS interoperability platform and external open data. BIM/GIS platform can provide spatial information services for indoor and outdoor seamlessly because it was developed based on GIS spatial data with BIM data. The linked external open data are V-World data, Seoul Open Data, and Architectural Data Open. Finally, the authors proposed the direction of development for BIM/GIS integrated platform to provide advanced Smart City services.

oneM2M has been adopted to national and global smart city platforms leveraging its benefits, oneM2M platform assures interoperability to devices and services with standard APIs. Existing access control mechanisms in the standard should be extended to easily distribute smart city data. Compared to the as-is standard, this paper proposes a new access control method with minimum human interventions during data distribution between data sellers and buyers. The proposal has been implemented as the new data marketplace APIs to oneM2M platform and used for data marketplace portal interworking. This also has been demonstrated with smart city PoC service.

In recent years, many people are living in a space limited by rapid global industrial development and economic growth, and rapid urbanization is underway, with the global urban population estimated to be more than 70 percent in 2050. Due to rapid urbanization, government-led smart city models are being developed and introduced to solve various urban problems such as disaster safety, air pollution, water pollution, energy shortage, disease, crime and transportation. However, since ICT technology of public housing is being developed as a type of social overhead capital project, it is necessary to develop micro-smart city projects that residents can feel by developing services such as public safety, living environment, living welfare, and energy management for public housing residents. Therefore, in this paper, the smart platform model of public housing for smart city in the era of the Fourth Industrial Revolution is planned and presented.
