생활공간의 혁신적인 발전은 U-City라는 형태로 추진되고 가시화되고 있으며 특히 U-City의 옥외 공간에서 이뤄지는 서비스는 공간이 지능화되고 다양한 형태의 단말을 통해 보다 능동적이고 찾아가는 형태로 제시되고 있다. 그러나 이러한 서비스를 실현하기 위해서는 옥외공간에 다양한 서비스 장비가 설치, 운용되어야 하는데 KT는 이를 효과적으로 구성하고 구현할 수 있는 IT인프라로서 도시 야간 필수 시설물이며 도시미관을 해치지 않는 가로등 형태로 수용하여 서비스 구현에 필요한 장비를 수용하는 지능형 가로등 U-Pole을 개발해오고 있다. 본 논문에서는 U-Pole로 구성된 현장 서비스 제공 플랫폼과 옥외 공간지능화 서비스 사례를 소개하고자 한다.

유비쿼터스 컴퓨팅 환경의 사용자는 환경에서 제공되는 수 많은 서비스 (U-서비스)중에서, 사용자의 특성, 필요, 선호도에 따라 적합한 서비스를 쉽게 선택하여 사용할 수 있어야 한다. 본 논문에서는 사용자의 맥락에 따라 U-서비스를 선택하고 상호작용을 할 수 있는 사용자 인터페이스로 personal companion 을 제안한다. Personal companion 은 서비스 발견 기법과 카메라 기반의 상호작용 방법을 통해 서비스를 선택하고, 선택한 서비스의 인터페이스를 개인화 함으로써 다수의 서비스와 직관적인 상호작용을 가능케 한다. 이를 위해 기존 마커의 가시성을 줄이는 새로운 형태의 마커를 제안하고 카메라 기반의 상호작용 방법에 응용한다. Personal companion 의 유용성 검증을 위해 PDA 와 UMPC 플랫폼에 구현한 후, 스마트 홈 테스트 베드의 여러 응용 서비스를 선택하고 상호작용을 하는데 적용하였다. 제안한 personal companion 은 유비쿼터스 컴퓨팅 환경에서 사용자와 U-서비스를 사용자 중심적으로 연결시켜 주는 중요한 매개체의 역할을 할 수 있을 것으로 기대된다.

This paper proposes a method and its implementation for searching, converting, and delivering composite events and actions in the U-City Integrated Management Platform to process them efficiently through allocation and collaboration between the platform and u-services. The purpose of this method is to, when a composite event occurs, execute prompt and correct measures to reduce the damage caused by the event and prevent its spread. The proposed method also helps to simplify the complexity of corresponding business processes by modifying composite events and actions that are frequently added, delete, and revised, and delivering them to u-service systems.

This study was carried out the exercise monitoring utilizing mobile device which is easily accessible and personalized exercise prescription based on it. For this, a variety of exercise monitoring and status of those were investigated and suggested the potential of personalized exercise prescription. If individual users send their body and vital informations using a mobile device, all informations are collected in u-Fitness center. After then exercise expert provide a customized prescription based on the collected information and feed data into database of u-Fitness center. System of U-Fitness center will provide the best personalized exercise prescription by automatically connecting to the content providers. In the future, a variety of mobile devices and services will work together and it can be evolved as an open platform that can be used for multiple services according to the needs of individual users on a single platform.

In Web2.0 environment, with advanced platform technologies, global vendors such as Google, Microsoft and Yahoo provide competitive geospatial services based on global map and satellite image. But the relatively low level of platform technologies has not rapidly increased the land information and geospatial service markets in Korea. For the ubiquitous next generation Internet, as a one of the R&D projects by Korean Land Spatialization Group, the project for platform technologies has being made to provide customized land information and geospatial service. The platform technologies can be categorized for streamming, mashup and geosearch. More specifically, the 2D/3D Hybird streamming engine, mashup engine for u-GIS service and next generation search engine for land information have being developed. In this context, the strategies for efficient development and use of geoweb platform technologies are required. This study surveys the present geospatial products and services using of platform technologies to propose the strategies for efficient development and use of platform technologies. The strategies for efficient development and use of platform technologies can be proposed focusing on target market and each of platform technologies.

To propagate clinical disease management service, there should be built a ecosystem where service developers, service providers, device suppliers closely cooperate for u-Health platform. However, most u-Health platform is difficult to build an effective ecosystem due to the lack of secure and effective PHR(Personal Health Record) management, the lack of personalized and intelligent service, difficulties of N-screen service. To solve these problems we suggest the CDMP(Chronic Disease Management Platform) architecture. The CDMP is a software platform that provides the core functions to develop the chronic disease management services and performs a hub function for the link and integration rbetween various services and systems. CDMP is SOA based platform that enables a provision of reusability, expansibility and it provides open API where everybody can share information, contents and services easily. CDMP supports the multi platform system foN-screen service and the self management functions via SNS. In this paper, we design and implement the CDMP including PHR service based on hybrid data model for privacy preservation. Experiment results prove the effectiveness of hybrid model-based PHR service.

USN(Ubiquitous Sensor Network) is a core infrastructure that makes come true the u-life in the ubiquitous society through various services of area such as u-city and u-Health. Therefore, we need to reseach about the domestic standards to establish the core technique of USN. Currently, the status of USN standards is most of technical standard and reseach that are technology for sensor node implementation and a protocol for energy-efficient communication and interlock with existing network. But, Standard and reseach for sensor network, integration management of heterogeneous sensor networks for USN application, sensing data management and USN database structure definition such as application and middleware are weak level. In this paper, we researched for standard development of the domestic sensor network service and relevant standard analysis to configure SWE(Sensor Web Enablement) of OGC(Open Geospatial Consortium) for standarded plattform technoloy in part of the middleware. Also we researched that it's a connection between domestic TTA (Telecommunications Technology Association) standards and SWE Standard. Finally, we researched for standard service plattform architecture on sensor network through analysis on the possibility of applying OGC-based services platform.

This paper proposes a standard method for linking data between the U-City Integrated Urban Management Platform and u-service systems through systemization of event identification and standardization of event priority. By applying the proposed method, the incoming events to the Management Platform are listed and processed according to their priority of urgency. The application of the systemized event ID and standardized event priority enables prompt counter-measures against urban emergencies and disasters, which improves the efficiency of business processes by reducing the time and cost to complete required actions.
