운영체제 원격 자동설치시스템은 특히 다수의 호스트 컴퓨터로 이루어진 네트워크 환경에서 적용되어 운영체제 설치 및 업그레이드 시 유용하게 쓰이고 있다. 그러나 관리자의 설치시작 확인과정 없이 자동으로 진행되어 안정성을 보장받을 수 없고 하드웨어의 문제나 관리자의 소홀로 인한 운영체제의 반복설치 문제점이 있어 실 서비스 환경에 적용하기 어렵다. 본 논문에서는 기존의 문제점을 해결하기 위해 DHCP 프로토콜 변경을 통한 운영체제 원격 자동설치 제어방법 및 시스템을 제안하고자 한다. 호스트정보를 자동추가하고 관리자의 판단이 이루어지도록 설치대기모드 전환단계를 거쳐 실 서비스 환경에 적용할 수 있는 안정성을 확보한다.

A general medical information service in hospitals recently has been rapidly developed in the effective patient management due to the digitalization. In addition, the hospitals make an effort to support the medical information service in ubiquitous environment. A key requirement in ubiquitous environment is the ability to communicate between the image viewer system using the DICOM standard and a server system to support the medical information service. This paper describes a remote networking system based on the mobile terminal with RFID technology for the medical information service. In order to apply the overall configuration, we first implemented the DICOM viewer system, configured the database to store the patient information, and realized the server/client networking system in mobile terminal environment. In particular, this paper showed the capability for the medical image-based communication as well as the text-based communication.

It has recently been combined with advanced technologies such as AR and VR, and its application range is expanding to various forms of smart signage. However, until now, digital signage service that reaches us is installed in many floating populations such as bus stops, elevators, and banks and is used in the form of providing news, weather, and advertisements. In addition, large companies, government offices, and outdoor advertising companies occupy the market. The use of such services in small and medium-sized businesses and small retail stores is costly and expensive to manage. Also, it is difficult to generalize the market because services and solutions are being deployed in the market in the form of top-down. Therefore, in this paper, we proposed a digital signage system for transmitting a remote video advertisement that uses a show window in front of the store as a beam project screen for small retail stores, and can remotely set and manage and update it in OSGi service platform.

The purpose of this study was to identify the effect of the Smart Care ubiquitous healthcare service on hypertension management. Fifty one patients with inadequately controlled blood pressure (Systolic Blood Pressure ${\geq}$ 140 mmHg despite prescribed antihypertensive medication) from 4 local clinics participated in this study. Remote biometric monitoring and healthcare consultation via videophone was provided to the participants during 24 week - Smart Care service. The average number of blood pressure monitoring and the average day of remote consult using Smart Care Service system was 121 and 14.8 per participant. As a result of analyzing change in blood pressure during 24 weeks, there was a significant difference in blood pressure between baseline and 24 weeks. Systolic blood pressures of 86.3% participants were dropped within a normal range at 24 week. Smart Care u-health service could be effective in reducing blood pressure.

본 논문에서는 클라이언트/서버 형태로 긴급 이벤트 자동 호출 기능을 처리할 수 있는 원격제어 시스템을 설계하고 구현하였다. 웹 애플릿을 기반으로 구현된 클라이언트 시스템은 상황실에 위치하여 직접적으로 제어를 담당하는 서버에게 원격제어 명령을 내린다. 제어 명령은 서버시스템으로 전달되며, 서버시스템에 존재하는 구동기가 실질적으로 컨베이어 시스템을 제어하는 기능을 가진다. 여기서 컨베이어 시스템은 승용차 조립라인을 시뮬레이션 한 것이다. 이러한 원격제어 시스템에 이동 통신의 문자서비스를 이용하여 긴급한 상황을 자동으로 원격지에 있는 관리자에게 알려주는 기능까지 확대시켰다. 관리자는 원격 시스템을 항상 감시할 필요가 없이 어느 장소에서나 상황보고를 받을 수 있다.

This paper, discusses about the implementation of the remote control LED Lights in elevator facility Since 1990, the elevator dissemination has greatly increasing. Currently in the elevator most of people they can use smart devices anytime or anywhere to view and retrieve the information by using internet. Therefore, in this paper, efficient management of power LED and LED remote control LED lighting fluid, in order to control features and smart devices can be applied to Web services platform and OS-specific proposals. Additionally based on the configured UI technology and programs offered by the present, and the LED lights are offered through the simulation to efficiently manage technology to demonstrate the usefulness.

In this paper, an Android based ubiquitous interface for controlling service robots is presented. The robot server captures the images for the front view of the robot, makes a map of the environment and its position, produces a graphic image of its pose, and then transmits them to the Android client. The Android client displays them in the LCD panel and transfers control information obtained from touched buttons to the server. In the interface environment, we implement remote moving mode, autonomous moving mode, and remote operation mode for being used for versatile operability to the robot with limited screen of the smart phone. Experimental results show the implementation of the proposed interface in Android installed on Motoroi to control a service robot, and demonstrate its feasibility.
