A demand on the spatial data management has been rapidly increased with the introduction and diffusion process of ITS, Telematics, and Wireless Sensor Network, and many different people use the digital map that offers various thematic spatial data. Spatial data for digital map can manage to tile-based and feature-based data. The existing tile-based digital map management systems have difficult problems of data construction, history management, and updating based on a spatial object. In order to solve these problems, this paper proposed the data model for the feature-based digital map management system that is designed for feature-based seamless map, history management, real-time updating of spatial data, and analyzed the validity and utility of the proposed model.

Healthcare word means that supports and manages services related to health for prevent, cure, manage disease and stabilize physically or mentally. This paper presents base technology that supports a remote medical service to people including elderly and asthmatics comfortably. To be done, we gathered information which was acquired from SaO2(Saturation of Oxygen) Sensors and built HMI System based on wireless environment using these information.

Government is supporting development of home networking. But, this new system is much expensive to introduce in the home. And limit for establishment is so many in the home. Therefore, in this paper, Present direction of home automation system that can have high effciency into low expense, induction of automation system is easied in the home. Also, install can be easy and do remote control in PC, HP, PDA because use RF, DB.

본 논문에서는 RF 모듈을 탐재한 Atmega 시스템 설계를 통한 잠수함 원격 제어 시스템을 구현한다. 본 연구에서 제작한 RC 잠수함은 실제 잠수함의 원리와 비슷하게 잠항을 할 때는 소형펌프로 밸러스트탱크에 물을 채우고, 잠수를 할 때 수직타와 추진력을 이용하여 잠항을 한다. 이와 반대로 부상은 소형펌프로 밸러스트탱크 안에 물을 배수하여 WTC(방수실린더)안의 기압과 수직타와 추진력을 이용하여 부상을 한다. RC 잠수함은 크게 외부와 내부 그리고 방수를 하기 위한 WTC(방수 실린더)로 나누어진다. 송신 부는 RF 모듈, MCU(Atmega128), 키패드, 캐릭터LCD로 구성되며 수신부는 MCU(Atmega128), RF 모듈, 제어장치들로 구성한다. 제어장치에는 모형 잠수함은 추진력을 위하여 DC 모터에 스크류(프로펠러)를 장착하고, 방향전환 및 잠항과 부상을 위하여 RC 서보 모터를 사용하고 잠항과 부상을 위하여 펌프를 사용한다. WTC는 방수실린더로서 아크릴파이프를 이용하여 제작하고 방수를 위하여 아크릴파이프를 이용 여기에 MCU와 제어 장치들을 넣어 밀봉시켜 방수를 하여 완성한다.

This paper presents an active assisted-living system in wireless sensor and actor network (WSAN) in which the mobile robot roles an actor. In order to provide assisted-living service to the elderly people, position recognition of the sensor node attached on the user and localization of the mobile robot should be performed at the same time. For the purpose, we use received signal strength indication (RSSI) to find the position of the person and ubiquitous sensor nodes including ultrasonic sensor which performs both transmission of sensor information and localization like global positioning system. Active services are moving to the elderly people by detecting activity sensor and visual tracking and voice chatting with remote monitoring system.

In this research, we have developed a load/unload device capable of correcting the position automatically. Characteristic technologies such as compensation, control, guidance and communication have been modified and implemented on an existing electromagnetic guided AGV, helping to realize open system and distributed cooperation. We have applied the developed AGV with remote control and heterogeneous load/unload mechanisms in a machining system composed of various equipment such as machining centers, CMN and AS/RS and found that the AGV provided position error within $\pm$2mm.
