Recent increases in uncertainty and speed of market change are driving the adoption of new intelligent mobile office systems. Organizational information systems paradigm suggests that a right match between organizational characteristics and the use of technology is critical in producing desired results. Following such perspective this study developed the mobile office system case of Seoul Metropolitan Railway Transit(SMRT) in Korea. SMRT developed the mobile task-supporting environment that help the management of subway lines real-time without the restriction of time and space. They named the system as ST&F(SMRT Talk and Flash). They decided to develop the application systems in-houses they did not want to be overly dependent on external services in future changes and developments of the system. The new practice reduced the time for moving back and forth to 10% of their working time from previous 20%. The time used for paper works and administration chore also reduce to 10% of their working time from previous 30% on the average. The employees could use 80% of their time to concentrate on the completion of assigned task. The effects of this improvement resulted in the heightened efficiency of the use of human resources and the heightened level of railway safety. The case of SMRT shows that the mobile office system can be applied and extended to various business areas such as facility management and maintenance beyond such typical uses as sales and marketing support. Also, The result of case study will be a useful guideline on the construction and using of mobile office system.

The increase in the number of private automobiles has incurred various traffic problems. Globally, studies on MaaS(Mobility as a Service) has already been initiated to mobilize the use of public transportation in reducing private passenger cars in roads. This study aims to analyze the passenger's optimal route considering the transfer between different transportation modes through simulation, and analyze the effect of available route through the connected transportation modes. Sejong Special Self-Governing City was chosen as the study area due to its extensive transportation network. As a result of the analysis, the predominant obtainable route is derived either from using public transportation (i.e. bus and subway) only or by bicycle. However, it is also possible to use the car sharing and public bicycle to reach their final destination efficiently when paths that can be traversed were more scrutinized. When various transportation information and location-based services are introduced in smart phone applications, they can provide very useful information to passengers, and also promote social problems such as traffic congestion and environmental issues in the future.

The decline in the price of IT devices and the development of the Internet have created a new field called Internet of Things (IoT). IoT, which creates new services by connecting all the objects that are in everyday life to the Internet, is pioneering new forms of business that have not been seen before in combination with Big Data. The prospect of IoT can be said to be unlimited in its utilization. In addition, studies of standardization organizations for smooth connection of these IoT devices are also active. However, there is a part of this study that we overlook. In order to control IoT equipment or acquire information, it is necessary to separately develop interworking issues (IP address, Wi-Fi, Bluetooth, NFC, etc.) and related application software or apps. In order to solve these problems, existing research methods have been conducted on augmented reality using GPS or markers. However, there is a disadvantage in that a separate marker is required and the marker is recognized only in the vicinity. In addition, in the case of a study using a GPS address using a 2D-based camera, it was difficult to implement an active interface because the distance to the target device could not be recognized. In this study, we use 3D Depth recognition camera to be installed on smartphone and calculate the space coordinates automatically by linking the distance measurement and the sensor information of the mobile phone without a separate marker. Coordination inquiry finds equipment of IoT and enables information acquisition and control of corresponding IoT equipment. Therefore, from the user's point of view, it is possible to reduce the burden on the problem of interworking of the IoT equipment and the installation of the app. Furthermore, if this technology is used in the field of public services and smart glasses, it will reduce duplication of investment in software development and increase in public services.

'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.

재난발생 시 유관기관 간, 유관기관과 개인 간, 그리고 개인과 개인 간 재난대응에 필요한 정보를 적시에 주고 받는 것은 피해 규모를 줄이는데 결정적인 역할을 한다. 지금까지 재난상황에서 사용되었던 기존의 커뮤니케이션 수단은 TV, 라디오, 공공기관 통신망 등이었다. 그러나 TV나 라디오는 해당 기기가 주변에 없거나, 개인과 개인 간 정보 교환 시, 그리고 관련 통신망 자체가 무력화된 상태 등에서는 활용에 제한을 받게 된다. 또한 소방통신망 등 유관기관들이 사용하고 있는 통신망의 경우에도 재난의 종류에 따라 그 활용 폭이 달라질 수 있고 일반 대중에게 정보를 전파할 때는 사용할 수 없다는 단점도 존재한다. 이런 상황에서 최근에 급격히 발달하고 있는 모바일 네트워킹 기술은 재난대응 커뮤니케이션과 관련하여 새로운 돌파구를 제시하고 있다. 기존 커뮤니케이션 수단들과 달리 스마트폰 등의 모바일 기기들은 민(民)과 관(官)을 구분하지 않고 이미 거의 모든 개인이 소유하고 있는 상황이며, 이를 활용하여 항시 인터넷에 접속할 수 있는 환경이 구축된 상태다. 따라서 모바일 환경에 적합한 재난대응 커뮤니케이션과 관련한 연구동향을 정리하고 새로운 과제를 도출해 낼 필요가 있다. 본 논문에서는 크게 1) 모바일 네트워크 기반의 재난대응 어플리케이션 개발에 관한 연구와 2) 모바일 환경에서 소설 네트워킹 서비스를 활용한 재난대응 커뮤니케이션이라는 두 개의 주제를 중심으로 최근 연구동향과 향후 과제를 제시하고자 한다.
