최근 공공기관을 통해 CCTV 영상을 통합관리 하려는 움직임이 활발히 발생하고 있다. 하지만, CCTV의 수가 증가하고, 해상도가 높아지면서 통합관리시 저장비용, 검색비용 등의 문제가 예상되고 있다. 이러한 문제의 해결책으로 클라우드 컴퓨팅 기술을 들 수 있는데, 클라우드 컴퓨팅은 다양한 클라이언트 디바이스에서 필요한 시점에 인터넷을 이용해 공유 풀에 있는 서버, 스토리지, 애플리케이션, 서비스 등과 같은 IT 리소스에 쉽게 접근할 수 있는 것을 가능하게 하는 모델이다. 또한 모바일 클라우드 컴퓨팅은 클라우드 컴퓨팅과 다양한 모바일 기기를 결합하여 다양한 서비스를 제공하는 것이다. CCTV와 같은 영상을 생산하는 클라이언트를 모바일 클라우드의 단말로 보고, 영상 데이터를 클라우드 컴퓨팅을 이용하여 관리하면, 저가의 비용으로 대용량의 영상을 저장하는데 비용을 절감 할 수 있으며, 간단한 방법으로 병렬 처리로 검색을 할 수 있어, 검색 시간을 절감 할 수 있는 효과가 있다. 본 논문에서는 모바일 클라우드를 이용한 범용 영상 통합 관리 시스템 모델을 제안하고 이를 토대로 차량용 블랙박스 분야에 한정한 시스템 설계하고 구현하였다.

전 세계적으로 기후변화로 인한 기상재해의 발생 빈도가 증가하고 있다. 특히 기후변화로 인한 기온상승은 사계절이 뚜렷한 우리나라의 기후도 동남아와 같은 아열대 기후로 변하고 있는 추세이다. 기후변화 전망보고서에 따르면는 우리나라의 연 강우량이 현재(1,491mm)보다 약 11% 증가(1,658mm) 하고, 연평균기온이 현재 대비 2040년대 0.7℃, 2090년대 3.1℃ 상승할 것으로 전망했다. 기후변화에 의한 여름철 기온 상승과 겨울철 기온 하강은 에너지 소비량과 소비 패턴 변화를 유발하고 에너지 수요와 공급 불일치의 원인이 된다. 이에 정부에서는 기후변화에 적응하기 위해 화석연료 기반의 에너지 생산에서 그린에너지를 이용한 에너지 생산으로 전환이 효과적이라고 공표하였다. 이어 2050년까지 탄소중립 달성을 위해 신재생에너지르 통한 도전과제를 제시하였으며, 기업 및 공공기관의 RE100참여를 확대하고 활용 가능한 유망 재생에너지원을 발굴을 목표로 하고 있다. 이에 본 연구팀은 국가 기상재해·그린에너지 빅데이터 센터를 설립하여 정부의 다양한 이행수단의 근거 데이터를 제공하고, 민·관에서 활용 할 수 있는 그린에너지 데이터를 제공하고자 한다. 본 센터에서는 침수예측데이터, 풍력, 태양광, 소수력, 수열 잠재 에너지 데이터를 생산하고 있으며, 각 데이터에 대한 활용 및 서비스 방안을 소개하고자 한다.

Among e-government services, the intelligent CCTV control platform is a screening control service that utilizes artificial intelligence to display major objects such as people, cars, etc. to control personnel when they appear on CCTV. The operation of an intelligent CCTV control platform is expected to improve the quality of life of citizens by enabling rapid response in the event of an emergency and increasing the resolution of complaints. In this study, the benefits of the intelligent CCTV control platform, a non-market good, were estimated by applying the contingent valuation method (CVM), a choice experiment technique, to estimate the average willingness to pay per household and calculate the social benefits. As a result of the analysis, the average willingness to pay per household was estimated to be KRW 6,908 per year, and the economic benefits for the country as a whole were estimated to be about KRW 150.4 billion per year. This study is of academic significance as it extends the application of CVM to the field of intelligent e-Government services. The Intelligent CCTV control platforms is being actively discussed, this study has practical implications in that the benefits were estimated in monetary value.

In this study, various usage patterns were analyzed after establishing a data mart for micro mobility analysis based on the rental history of public bicycles in Seoul. Rental history data is origin-destination data that includes the rental location and time, and the return location and time. About 1500 rental locations were classified according to the characteristics of the location to create a 'station type' dimension. We also created a 'path type' dimension that displays whether the rental location and return location are the same. In addition, a derived variable called speed, which is obtained by dividing the distance used by the time used, is added, and through this, the characteristics of the riding area and the reason for the rental can be estimated. Meanwhile, administrative district link, administrative neighborhood link, and station type link were created to apply network analysis. Through this analysis, the roles and proportions of administrative districts, public facilities, and private facilities engaged in micro-mobility services were visualized. 49.9% of rentals occur at rental offices near transportation facilities, and half of them occur at rental offices near subway stations. The number of rentals during the evening rush hour is more than double that of the morning rush hour. When the path type is unidirectional, there is a fixed destination, so the distance and time used are short, and the movement speed tends to be high. In the case of round-trip, the purpose of use is exercise or leisure, so the distance and time used are long, and the movement speed is slow. It is expected that the results of the analysis can be used as reference materials for selecting new rental locations, providing convenient services for users, and developing user-specialized products.

A smart platform is defined as an evolved platform that realizes physical and virtual space into a hyper-connected environment by combining the existing platform and advanced IT technology. The hyper-connection that is the connection between information and information, infrastructure and infrastructure, infrastructure and information, or space and service, enables the realization and provision of high-quality services that significantly change the quality of life and environment of users. In addition, it is providing everyone with the effect of significantly improving the social safety net and personal health management level by implementing smart government and smart healthcare. A lot of information produced and consumed in these processes can act as a factor threatening the basic rights of the public and individuals by the informations themselves or through big data analysis. In particular, as the smart platform as a core function that forms the ecosystem of a smart city is naturally and continuously expanded, it faces a huge security burden in data processing and network operation. In this paper, platform components as core functions of smart city and appropriate security threats and countermeasures are studied.
