A tole-robot system for remote home-management has been developed. The tele-robot system is composed of a mobile robot system, server-computers and client-computers. The robot system is equipped with wireless camera and wireless controller so that the robot system captures the image remotely User makes the robot control command referring to the image feedback through internet. With such tole-robot system, the user can monitor and watch the inside of home by remotely maneuvering the mobile robot. The user can also save the received image of suspected scene on the client computer. Utilizing such function of tele-robot system, remote home-management and possible crime avoidance could be achieved.

In this monograph, we developed a Remote Courseware Management System so we can more easily cultivate a courseware with various multimedia applications through an easy interface with the internt. In the view of Developer of view, we could develop RCMS rapidly using the application of ASP.NET and have tried to adapt ourself to the future environment using it. ASP.NET provides much richer event programming model than ASP and event processor which are executed on Server. In the view of User, they can used the Internet service with equipment that they want at any place and any time. To control any kinds of courseware for Administrator and Users, we offered a variety of Multimedia applications and an easy interface and built a new style of web courseware.

In this paper, we propose the collaborative design system with which we can simultaneously modify the actual 3D CAD model by the remote control and have interaction on it. It enables instantaneous decision making among the multiple disciplines in distributed locations using the function of simultaneous access and video conference. It also provides the method of managing the consistency between design entities. This system consists of Collaborative Management Server, File Server, Solid Modeler Client, Remote Control Module and Client Module.

In order to promptly cope with the various requirements of consumers, the environment of product development is being globalized in manufacturing industrials. For this reason, it is necessary to build up an efficient collaborative system for communication between remote area designers. Specially, while Internet and information technologies were merged with the manufacturing or business process, the research for collaborative system has become an important issue. Therefore, we propose a Web-based Engineering Collaboration Framework using SPS(SharePoint Portal Server) which is an enterprise business solution that integrates information from various system into one solution through single sign-on and enterprise application integration capabilities, with flexible deployment options and management tool. Through a Web-based Engineering Collaboration Framework, designers can share knowledge assets and have a remote conference with others via web.

Today, the vehicle is used the mean of transportation as well as the mobile office with the third digital life space. So telematics is an emerging industry that has tremendous future potential. It is necessary the essential contents for telematics services : navigation map for navigation, POI, real-time traffic information etc. In this paper, we proposed the telematics contents server to manage the telematics contents with efficient performance in distributed environment. The telematics contents server transforms and stores the essential contents and provide it to user through standard interface. The telematics contents server is middleware to offer a rapid essential telematics contents management, client connectivity, and communications. It is useful for the telematics service provider to build telematics system under distributed environment.

The number of the enterprises which utilize network technology has been increasing for solving problems such as productivity improvement, market trend analysis, and material collection for making decision. Especially, the management of equipment and the recovery time reduction when machines break down are very important factors in productivity improvement of the enterprise. Currently, most of the remote trouble diagnosis of equipment using the internet have just one function of transmitting the trouble information to the user. Therefore it does not directly reflect the user's recovery experience or the developer's new recovery methods. If the user's experienced recovery methods or the developer's recovery methods as well as the basic recovery methods are reflected online or on the internet, it makes it possible to recover faster than before. In this paper, we develop a Remote Monitoring Server (RMS) for chip mounters, and make it possible to reduce the recovery time by reflecting the user's experience and developer's new methods in addition to presenting the basic recovery methods. For this, trouble recovery concept will be defined. Based on this, many functions(trouble diagnosis, the presentation of the basic recovery methods, user's and developer's recovery method, counting function of the trouble number of each code, and presentation of usage number of each recovery methods) were developed. By utilizing the reports of the actual results of chip mounter and the notice function of the parts change time, the rate of operation of the chip mounter can be improved.

다수의 CCTV(Closed Circuit Television)로 광범위한 지역을 관리하는 보안 감시 시스템에서 시간과 장소에 구애받지 않고 CCTV를 원격으로 실시간 모니터링 할 수 있도록 어플리케이션을 설계 및 구현했다. Xcode를 사용하여 개발된 어플리케이션은 폐쇄적인 중앙 관제 시스템으로부터 안전한 관리자 인터페이스를 제공하는 역할을 한다. 효율적이며 직관적인 인터페이스를 통해 어플리케이션은 중앙관제 시스템에서 제공하는 실시간 상황 알림보고 및 상황 인지 추론 결과를 원격의 관리자에게 전달한다. 사용자의 편의를 위해, 어플리케이션은 이벤트 발생시의 push 알림, SNS(Social Network Service) 연동을 포함한 다양한 기능을 제공한다. 실시간 모니터링을 위해 카메라의 화면을 스트림 해줄 서비스는 Wirecast와 Wowza media server를 이용한다. Wowza stream engine은 실시간 스트리밍을 돕는 개발규격에 맞춘 URL을 제공한다. 이를 통해 모바일에서 실시간 스트리밍 결과를 받아 볼 수 있으며, 그 과정에서 발생되는 자원 소모에 관련된 성능분석을 보였다.
