u-City(Ubiquitous city)는 유비쿼터스 컴퓨팅과 정보통신 기술을 기반으로 다양한 u-서비스(Ubiquitous service)를 제공하는 도시이다. u-서비스를 제공하기 위해서는 시스템이 주변 상황(Context)을 인지하여 사용자와 상호작용을 지원하는 상황인지 기술이 중요하다. 최근 상황인지(Context-aware) 기술은 지능형 회의실이나 스마트 홈을 개발하기 위하여 활발히 적용되고 있으나, 광범위한 도시공간을 대상으로 하는 u-서비스를 구현하기 위한 연구는 미진한 실정이다. 본 논문에서는 홍수 모니터링 서비스를 대상으로 온톨로지 기반의 홍수 상황인지 모델을 제안한다. 모델설계를 위해 현재의 홍수 모니터링 시스템을 분석하여 요구사항을 도출하고 홍수 모니터링 시나리오를 작성하였다. 상황 데이터를 분석하고 상황 데이터 수집을 위한 센서(Sensor) 온톨로지(Ontology)를 설계하였다. 다음으로 센서 온톨로지를 통해 수집한 상황 데이터를 추론하여 적절한 서비스를 제공하기 위한 홍수 상황인지 모델을 설계하였다. 제안한 모델은 향후 다양한 u-서비스를 설계하고 구현하는데 응용모델로 활용할 수 있을 것이다.

도시로의 집중현상에 따라 차량이 증가함으로 한정된 공간에서의 도시교통난이 계속 악화되고 있는 실정이다. 도로상의 불법 주ㆍ정차위반차량으로 인해 차량소통에 불편을 주고, 주거 및 교통환경을 저해하기 때문에 견인업무는 주차정책을 실현시키는 강력한 수단으로써 반드시 필요하지만, 우리나라에서 불법 주ㆍ정차 차량의 견인부분에 대한 연구 및 결과는 극히 미비한 실정이다. 이에 따라 본 연구에서는 우리나라 주요 도시를 대상으로 불법 주ㆍ정차 차량의 견인운행 실태 및 특징을 비교, 견인제도의 문제점을 분석하여 개선방안을 검토하고자 하였다. 이의 내용으로는 각 시에서 추진 및 계획중인 지능형 교통체계(ITS), 버스 정보시스템(BIS) 및 차량 위치 자동 표시기(AVM)를 연계시켜 공차거리를 줄이는 등의 첨단체계를 구축하여 견인차량에 대한 운영을 효율적으로 하여야 할 것이고, 요금의 구조도 서울을 제외한 기존의 3단계 톤급별 요금구조에서 장래 대형차의 견인을 감안한 4단계의 톤급별 요금구조로의 조정방안이 필요하다. 견인비용에 있어서도 대부분의 도시가 수년전의 여건을 근거로 산출한 결과를 기준으로 요금을 징수하고 있어 현실에 맞지 않는 요금체계를 적용시키고 있는 실정이다. 따라서, 견인비용부분에 대하여도 장래의 경제여건을 감안한 탄력적 요금체계를 설정하여 경영합리화를 유도함이 바람직하다. 부가하여, 견인원가에 대한 사례분석 결과는 부천시를 중심으로 하여 현실성 있는 견인비용을 제시코자 하였다.

The U-City comprehensive plan has been settled on November in 2009 by U-City law which was enacted in 2008. On this, the U-City plan's framework which local governments established has been set. However, those who work for U-City in local governments and private sector would be fallen into confusion because they have not fully understood yet the concept of planning system in the U-City plan. In this condition of the early stage, some problems that are overlapping investments and lack of coordination between plans may occur. On this background, it is needed to understand the U-City plan's status and role by figuring out the relationship between U-City plan and other related plans. The goal of this paper is to suggest implications that are differences and similarities for coordination among the plans through a comparison with detailed instructions and laws related to U-City planning.

Due to abnormal high temperature, electric power demand has exceeded the backup power reserved for emergency case, hence, resulting in a major power outage. In today's overcrowded cities, the unexpected disruption in energy supply and demand is a major threat to the enormous economic damage and urban malfunctions. Existing methods for estimating the demand of the emergency power source do not lend themselves to predict the actual demand in the spatial dimension of the city. In addition, the reserve power is arbitrarily distributed in the case of emergency. This paper presents a method that predicts the emergency power demand using the spatial distribution of emergency power demand by applying the daily energy consumption intensity and emergency power demand according to urban spatial information and building use.

This study explores potential capability of a machine learning approach for monitoring urban morphology based on an evident case study. The case study conveys year 2006 investigations on interpreting urban morphology of Boston Main Streets by applying a machine learning approach. From the lesson of the precedent study, in 2016, another field research and interview was conducted to compare changes in urban situation, data commons culture, and technology innovation during the decade. This paper describes open possibilities to advance urban monitoring for morphological changes. Most of all, a multi-participatory data platform enables managing urban data system in real time. Second, collaboration with machines with artificial intelligence can intervene the framework of the urban management system as well as transform it through new demands of innovative industries. Recently, urban regeneration became a dominant urban planning strategy in Korean, therefore, urban monitoring is on demand. It is timely important to correspond to in-situ problems based on empirical research.

It is important to manage the underground facilities efficiently because they are directly related to the convenience and safety of citizens. But the fact that the different agencies take on a role of managing the underground facilities respectively makes it impossible. So Korean government has exerted great efforts to solve this problem through several projects. Korean government expects that the ubiquitous technologies such as sensor and wireless communication in the domain of the underground facilities management will be useful. It is main duty of u-City Management Center to monitor several situations about the underground facilities using ubiquitous technologies. But there is no consensus about what concrete situations it has to monitor even though u-cities under construction. Because local governments or related companies are in charge of carrying out these roles yet, there is no legal basis on which to do these tasks by the center. And it is needed to develop new technologies for u-services efficiently. Because technologies for u-service are vast, various and converged, so it necessary to develop them according to priority or in cooperation with other developers. In this paper, we classify the monitoring items for each facility which were investigated by a recent research. It is expected to make use of defining the role of the center and developing technologies with u-service.
