With the advent of high technologies such as the 4th Industrial Revolution and artificial intelligence and big data, efforts are being made to solve urban problems and improve the quality of life by applying new technologies in the smart city field. In addition, as carbon neutrality has emerged as an important issue due to global warming, smart city energy platform technologies such as urban energy management, efficiency improvement, and carbon reduction are in the spotlight. In order to effectively manage urban energy, energy resource information such as electricity, water, gas, hot water, heating, etc. must be collected from the management system of various energy utilities and managed on the central platform. The centrally integrated data is delivered to external city management systems that require city energy information through an energy platform. This study developed a CIM profile for smart city energy monitoring required to provide energy data to external systems. Electric data model were designed using the CIM class of IEC 61970, and water, gas, and heat data model were designed in compliance with the UML-based design ideas of IEC 61970.

Recently, Korea has been attracting the attention of smart city as a solution to urban problems along with the era of Forth Industrial Revolution. However, tourism, industry, and specific high-class residential complexes are being formed, and the disabled with information such as the elderly and disabled who can actually get help are not experienced. This study establishes the concept of smart city suitable for domestic and derives the priority of physical and non-physical elements of smart city considering information weakness. Smart City considering disabled with information has concluded that not only physical elements but also non-physical components are important, and derive the differences between the experts and the priorities of actual information weak people. We will propose a smart city development direction that takes into account information weak people that can be developed and advanced in response to the needs of information weak people.

This study proposes a method for acquiring and managing basic information on building, which is continuously updated through construction and re-construction, in order to implement 3D-GIS based on geometric shape information and building information. First of all, distinctions between BIM and GIS information models are described, and then an overview of CityGML for virtual city and its Level of Detail are introduced. At last, a prototype for extracting building geometry from BIM data in accordance with CityGML is presented for demonstration. By using IFC data from BIM, this approach enables a lot of firms and contractors in building industry to utilize their 2D/3D, data on sites and buildings, and also to save many effects for generating exterior and interior building models which are inevitable for implementing National GIS.

'08.3월 U-City법이 제정되었고, '09년에 U-City법에 근거한 제1차 유비쿼터스도시종합계획 (이하 U-City종합계획)이 수립되었다. 이후 계획에 따라 U-City R&D, U-City시범도시 지원사업 등이 추진되었으며, 기술, 서비스, 인력양성, 산업지원, 법제도 개선 등 다양한 부문에 U-City 지원 정책이 시행되었다. 이로 인해 국내 U-City 사업이 활발히 추진되었으나 주로 공공 주도의 신도시를 중심으로 구축되어 과도한 건설비용 및 관리운영비 부담, 중복투자 등의 다양한 문제를 발생하게 된다. 결국 신도시 조성 개발이익을 통한 U-City 구축은 건설경기의 침체와 함께 심각한 위기를 맞게 된다. 하지만 새정부 출범 이후 U-City는 창조경제 대표사업으로 채택되어 재도약할 수 있는 계기가 마련되었고 정부는 지역경제 활성화의 일환으로 도시재생사업에 U-City를 접목하는 등 U-City 부흥을 위한 시도를 지속적으로 하고 있다. 특히 신도시 개발로 치우쳐서 발생된 기존도시와의 불균형을 해소하기 위해 다각도로 해결방안을 모색하고 있다. 이에 현 시점에서는 기존도시에 초점을 맞추어 U-City 방향을 살펴보는 연구가 필요하며, 기존 신도시형 U-City가 추구했던 정보통신 위주의 계획에서 벗어나 지역특성 및 수준 등을 고려한 도시계획적 측면으로 접근하는 것이 바람직하다. 본고에서는 국내외 스마트시티 동향을 파악하고 우리나라의 신도시개발형 U-City 구축 현황의 문제점을 진단하여 기존도시형 U-City 구축의 필요성을 도출하였다. 이를 토대로 실효성 있는 기존도시 U-City 구현을 위하여 도시계획적 관점에서의 고도화 방안을 모색하고자 한다.

This study starts from the question if the characteristic of existing conventional site-specificity can be applied to the modern city space in information media era as it is. The evolution and spread of media technology acted as the catalyst which establishes the identity of an individual and promotes the social sense of belonging as the new type of community member as well as expanded the communication territory of man. Moreover, as the perfect merge of third dimensional space with second dimensional media was accomplished, the meaning of city as the place is getting changed and extended to city space as the information platform which integrates and intermediates the various information composing city. Hereupon, this study is willing to analyze the limits which the characteristics of physical, active and meaningful elements which are the forming primary factors in the existing place theory have and establish the new meaning of city as the place through the case studies which are applied by the characteristics of hyper spacio-temporal, mobility and polysemy as the characteristics transformed by information platformization of city space.

U-City means the high-tech city that applied ubiquitous technology and information communication technology. U-City aims to intensify urban competitiveness and to improve the quality of residents' life through efficient management of the urban. Currently, 77 U-City projects is underway. The each project cost and scale estimate is not clear in the absence of the U-Service Standardization Model. So, many of the project are trouble about making a production the proper number of U-Service or the cost of project. The excessive service construction is reflected on the construction costs, which leads to the rise of sales price and passes onto the executor of a project as a burden of the project costs, and the problem of the delay of the change-over occurs due to supporting the operation costs for the operation of the constructed service and the demand for additional installation of facilities between a local autonomous entity and the executor of a project. In this paper, we suggested the U-Services Construction Standardization Methods and proposed the standardization services guideline of crime prevention services. U-City services in the future are able to maintain the consistency of the system through the utilization of the proposed standard model. As a result, the U-City project's pre-estimated cost and scale can be extracted.

The smart city is one of the most promising, prominent, and challenging applications of the Internet of Things (IoT). Smart cities rely on everything connected to each other. This in turn depends heavily on technology. Technology literacy is essential to transform a city into a smart, connected, sustainable, and resilient city where information is not only available but can also be found. The smart city vision combines emerging technologies such as edge computing, blockchain, artificial intelligence, etc. to create a sustainable ecosystem by dramatically reducing latency, bandwidth usage, and power consumption of smart devices running various applications. In this research, we present a comprehensive survey of emerging technologies for a sustainable smart city network. We discuss the requirements and challenges for a sustainable network and the role of heterogeneous integrated technologies in providing smart city solutions. We also discuss different network architectures from a security perspective to create an ecosystem. Finally, we discuss the open issues and challenges of the smart city network and provide suitable recommendations to resolve them.

Smart city, which employs information and communication technology (ICT) to resolve urban problems, is gaining more research attention in the innovation research. However, most previous studies regard citizens as merely passive accepters of the smart city services, focusing on individual private values. The present study aims to expand existing limited perspectives by applying public value management theory. Drawing from the literature review, we developed a dual perspective that a smart city service should encompass: private and public value. Then we set up a causal relationship between the value recognitions and intention to adopt smart city services. We further related antecedent variables to the dual value recognition in terms of citizens' characteristics: prior knowledge, personal innovativeness, and citizenship. Two case subjects among currently operating smart city services in South Korea were selected to empirically investigate our hypothesis. Results confirm the recognition of both public and private value is significantly related to the citizens' personal characteristics and resultant attitude towards acceptance and support for diffusion of the smart city services. This study is expected to provide useful implications for a new angle for the recipient of the smart city services, value orientation of the services, citizen's participation, and method selection for promotion.
