인스턴트 메신저는 데스크탑 PC뿐 아니라 PDA, 핸드헬드 PC 같은 개인용 무선정보기기에서도 활발하게 이용되고 있다. 그러나 대부분의 메신저가 데스크탑 환경을 고려한 기능을 그대로 사용하기 때문에 이동성이 있는 무선 환경에서는 활용성이 떨어지고, 사용하기에 불편한 단점이 있다. 본 논문에서는 리눅스 환경에서 사용자 음성인증로그인, RF 모듈을 이용한 자리비움 자동변환, 단문메시지서비스(Short Message Service) 등 무선 환경에서 필요한 기능을 제공하여 사용자 편리성을 제고한 무선 인스턴트 메시징 시스템의 설계와 구연에 대해 기술한다. 구현된 시스템은 과일전송과 단문메시지서비스를 위한 재버(Jabber) 기반의 프록시와 SMS 송신모듈을 갖는 서버와 USM(Ubiquitous, Smart, Mobile) 클라이언트로 구성된다. USM 클라이언트는 본 논문에서 라이트 XML 파서를 내장하여 메시지 통신시 클라이언트의 작업량을 크게 줄여 우선 클라이언트 프로그램의 최적화를 꾀하였다.

This paper deals a watt-hour meter monitor system applying a Power Line Communication (PLC) MODEM and a Data Concentrator Unit (DCU) which can apply to Internet map based Graphical User Interface (GUI). The PLC MODEM is profitable by saving the cost of installing dedicated wiring, and Internet map GUI also is able to contribute an easy access to monitoring system for non export users. This system makes it possible to monitor the amount of electricity of previous/ current month metering data via Internet mapping service. The implement system can easily apply a PC-management for the electric charges and maintenance with gathering the metering data.

This paper aims to develop the One-In-One web solutions that can work in PC, tablet, notebook, and smart phone depending on the flow of the ICT times to promote the marketing of the technology. The characteristics of this web solutions can be used to a image viewer system of 3D array type for PC, tablet, notebook, and smart phone. It is implemented in the design of 3D display slide show type. And it is developed an image viewer system, which enables users to use by utilizing the links manner ICT base required by each channel of the image. This is the 3D photo viewer PR solution developed in the way that anyone can use easily without the knowledge of programming in various areas such as public relations, business, and education.

Puretone audiometer, which is a machine used for measuring the minimum hearing threshold, can be cost-effectively implemented using computer with sound card and software. In this paper, we describe a puretone audiometer which has been designed and implemented based on a general PC with sound card. It supports air conduction and bone conduction test taking with automatic masking. It also provides multiple modes consisted of self-test, auto-test and manual test mode. Such multiple modes makes it possible to use in various environments like as home and/or hospital. Through measure of waveform of output voltage and sound pressure, we verified that puretone audiometer of this paper properly operates.

As computing environments are more rapidly developed, an adaptive and intelligent services using post PC such as PDA. Laptop, and Tablet PC in case of rounding and examining patients are highly demanded. The objective of this study is to design and implement a context-awareness support system based on voice service for medical environments. To achieve it, we propose a context middleware which plays an important role in recognizing a client with PDA by using a Bluetooth wireless communication technology as well as in executing an appropriate execution module, like delivery for diagnosis information of patients, according to the staff's context acquired from a context server. In addition, the context server functions as a manager that efficiently stores context information such as client's current status, physical environment, and device resources into a database server. Finally, for verifying the usefulness of the proposed system, we develop an application system which provides voice playing services for notification of other physicians through our context middleware.

Simulation system was introduced and used a lot in the fields of aviation, vessel, and medical treatment. 3D Simulation system has been used quite insufficiently as it requires a lot of system resource and huge amount of computer calculation. As the graphic card performance and simulation function developed, however, PC based simulation has been activated and is verified of its possibility as an educational software. However, educational institutions need to invest huge amount of budget and manpower to purchase and maintain CT Equipment. For such a reason, educational institutions entrust their students to hospitals for indirect experience of operation or for mere observation. This study, therefore, developed a CT Virtual reality education system with which medical CT Equipment can be directly operated in PC based 3D Virtual environment.

Recently, multi client PC technologies that several users can use one set of computer at the same time are being designed to use the surplus computer resource. In general, as the existing PC management system considers only a single client PC that only one user uses a computer, various kinds of complicated problems may be arisen. This paper designs and realizes a remote management system that can monitor and control the information used in the windows based OS multi-client using WMI technology. The proposed system herein uses WMI technology and newly defined client management protocol and provides the monitoring and control functions on individual resource use information of multi-client. As well, it provides a communication function between the server and the client, and locking setting and access control functions.

This paper presents a human friendly system using fuzzy inference as a Part of study to embody intelligent ship. We also build intelligent ship's steering system to take advantage of speech recognition that is a part of the human friendly interface. It can bring an effect such as labor decrement in ship. In order to design the voice instruction based ship's steering gear control system, we build of the voice instruction based learning(VIBL) system based on speech recognition and intelligent learning method at first. Next, we design an quartermaster's operation model by fuzzy inference and construct PC based remote control system. Finally, we applied the unposed control system to the miniature ship and verified its effectiveness.
