In this paper, We are proposed the real-time monitor and control mechanism for intelligent robot called URC(Ubiquitous Robotic Companion). URC are intelligent robots designed as to interact with external digital device that can communicate through wire or wireless by integration the network and information technology into traditional robot. In this paper, we implemented the result of this study into the target robot called ISSAC4 and proved its practical worth. We designed it as be able to control on remote by such web browser as anywhere and anytime that show a status information for several controllers, devices, actuators and sensors of robot and guarantee a continuity of real-time image transferring by Client-Pull method and moving control of robot.

Streaming Technology can support the real-time playback without downloading and storing multimedia data in local HDD. So, client browser or plug-in can represent multimedia data before the end of file transmission using streaming technology. Recently, the demand for efficient real-time playback and transmission of large amounts of multimedia data is growing rapidly. But most users' connections over network are not fast and stable enough to download large chunks of multimedia data. In this paper, we propose an intelligent IP streaming system based on personalized media service. The proposed IP streaming system enables users to get an intelligent recommendation of multimedia contents based on the user preference information stored on the streaming server or the home media server. The supposed intelligent IP streaming system consists of Server Metadata Agent, Pumping Server, Contents Storage Server, Client Metadata Agent and Streaming Player. And in order to implement the personalized media service, the user information, user preference information and client device information are managed under database concept. Moreover, users are assured of seamless access of streamed content event if they switch to another client device by implementing streaming system based on user identification and device information. We evaluate our approach with manufacturing home server system and simulation results.

This paper proposes the wireless integrated service for controlling networked appliances. Using wireless devices such as celluar phone and PDA which can communicate through Bluetooth and CDMA technology, home appliances are accessed and controlled from outside of house. The XML and the SMS message format is designed to specify controlling information for home appliances. Also the mobile agent and the message processor for networked appliances are implemented in the home gateway. In order to verify the proposed service system, a universal remote controller for cellular phone and PDA and network appliance simulator on web browser are implemented. Correct operation is verified through simulation using them.

Although a type of Web-based education has increased continuously, it has provided an environment that students use textbooks which are forms of homepage, make a note of lecture on Web browser, save the contents of note and use them again. Therefore, this thesis proposes a web note, MyNote, that students draw lines and write notes about the lecture using VML and DHTML on Web. Here, the contents of the note are saved in database with a form of text-based VML made dynamically using ASP. The document used with teaching material is downloaded from Web server to Web client and the content of VML is done from database. Using MyNote, students have their own libraries on Web. The content of note Is saved and printed on Web, and learners can relearn because they can review the content.

Purpose As the amount of data became enormous, it became a time when more efforts were needed to find the necessary information. Curation is a new term similarly to the museum curator, which is a service that helps people to collect, share, and value the contents of the Internet. In SNS, hash tag is used for emotional vocabulary to be transmitted between users by using (#) tag. Design/methodology/approach As the amount of data became enormous, it became a time when more efforts were needed to find the necessary information. Curation is a new term similarly to the museum curator, which is a service that helps people to collect, share, and value the contents of the Internet. In SNS, hash tag is used for emotional vocabulary to be transmitted between users by using (#) tag. Findings This study base on seven emotional sets such as 'Happy', 'Angry', 'Sad', 'Bad', 'Fearful', 'Surprised', 'Disgusted' to construct 327 emotional seeds and utilize the autofill function of web browser to collect 1.5 million emotional words from emotional seeds. The emotional dictionary of this study is considered to be meaningful as a tool to make emotional judgment from unstructured data.

Recently many ASP applications have been released which enable them to accept, save and manipulate files uploaded with a web browser. The files are uploaded via an HTML POST form using RFC 1867 In particular, the file transfer via the HTTP port is getting more important because of the current Internet security issues. In this paper, we implement a form-based ASP upload component and disclose explicitly most of the main codes. That is, the open source might be helpful to develop the new ASP applications including file upload function in the future. We also show the upload time and CPU usage time of the proposed upload component and compare with the well-known commercial ones, showing the performance metrics of the proposed component are comparable to those of commercial ones.

RSA is the most widely used public key algorithms. Payment via the SSL communications, and user authentication using RSA secure shopping mall that can protect the user's valuable information in the process of building. SSL-based electronic signature technology and encryption protocols for this technology are electronic documents are delivered to the other party through a separate encryption process, the information sender to enter information on a web browser (user) and the recipient (the Web server of the site Manager), except you will not be able to decrypt the contents. Therefore, the information is encrypted during the transfer of electronic documents even if hackers trying to Sniffing because its contents can never understand. Of internet shopping mall in the user authentication 'and' Communications' SSL secure shopping mall built with the goal of the methodology are presented.

Website creations and their renewal process are very difficult due to ever-changing mobile environments such as various operating systems and mobile devices. In this regard, HTML5 serves as the solution and guideline to developing well-functioning websites. Mobile websites using HTML5 can provide consistent contents and services even though users access them through various OS or device types. This paper examines a possibility of the HTML5-based website for a local private college located in Busan. For this, location-based map service and semantic auto dialing webform service have been implemented. After making the website available, students and staff members were satisfied with the improvement in the speed of loading time and error free contents service. In the future, the rest of HTML5 functionalities are planned to be implemented sequentially.

Due to the recent explosive progress of Web, We can easily access a large number of images from m. In this paper, we describe our approach of developing a general purpose content based image retrieval system over the H using a Web agent. The Web agent extracts text information of images from the links and file contents in HTML. The proposed system retrieves the images from database using the query by sketch and the query by example on Web browser. Experimental results demonstrate the effectiveness of the new approach.

The main contents of this paper is to design a system that can remote control the most of the LED lighting device in the market. In order to realize the device driver, we choose the communication mode Zigbee, PLC, RS232 and RS485. Using client-server system, LED lighting device can be controlled just through web browser.
