  • Web streaming environment need a suitable video playback service technique, a streaming technique for real-time delivery and an efficient control technique due to its limited environment. In this paper, we propose an effective control technique for real-time media stream playback as a connection technique between the high-quality media player and web browser based on Linux environment. The proposed stream control technique presents control data through 050 on media playback screen of web browser, and process the user's input data. It acts GUI-independently, and is designed considering addition and extension for control data.

  • As the requirement of user for robot functionality, the function and interface for controlling the robot system is more sophisticated and complicated. Accordingly development process of robot is more complicated and it takes much longer time to develop a robot system. Software development using project management tool is more important in software engineering because of the complexity of software, especially robot system. This paper proposes SEED (Software Engineering Equipment for Development), which is a web-based and integrated software engineering tool to provide independent tools for robot software development. SEED includes the document management tool, the software configuration management tool, the software testing tool on developing robot software and provide a functionality of collaborated and remote development due to WEB-based operations.

  • Recent natural disasters like flooding and slope collapse have shown the need for natural risk management system, as they endanger directly public health and cause severe damages on the national economy. In order to improve the efficiency of risk management systems, this management system based on AANN(Auto-Associative Neural Network)is proposed in this paper. AANN can be effectively used for identification of abnormal data and data compression. The proposed AANN-based risk management system collects and stores measurement data from sensors and transmits them to remote server for web-monitoring. Generally, it is desirable to transmit the compressed data instead of raw data in normal state. However, if dangerous situation happens, rapid tramission of measurement data should be required. These requirements are easily satisfied by using AANN. In order to verify the feasibilities of the proposed system, The AANN-based risk management system is applied to slope collapse monitoring system.

  • This study investigated the effects on young children's vocabulary and reading ability of the comprehensive language-teaching program using web-based picture books. The comprehensive language program was put into operation for 9 weeks with a classroom teacher who had in-service training for this program. The language course for the 23 children in the control group consisted only of ordinary language activities using teacher-made picture cards. Test results analyzed by t-test showed that the 25 children in the experimental group gained more than the control group on reading attitude including the concept of reading, accuracy, verbal expression, participation, contents and originality. Also, the ability to read a fairy tale aloud increased in the experimental group.

  • In this paper, client/server model for remote conveyor control and monitoring system is designed and implemented to simulate the product line of vehicles. The client system located at the monitoring office is using a web applet based system, and sends some commands to the server system which guards and controls the conveyer system directly. And server system is implemented as the web based system by using Java programming language too. The system has a distributed database system environments to manage and maintain the product line of conveyor system.

  • As the industry is developed, uses of various electric motor are increasing from general home to various fields of industry, and the kind becomes various daily. For these reasons, it is required to study the remote control and a package management about change of a speed drive system the supervision of administration appliance by real time, and the collection and process data together using internet prevailed on industry whole. Also, we can expect big effect in time and space, side of cost-cutting by control directly and manage appliance through internet. This paper deals with the development of a Web-Based remote control system for permanent magnet synchronous motor drives. The client/server system using TCP/IP protocols and DSP controller for remote control through internet and the Web interface that users can confirm data and state of PMSM is developed. This system is available for driving, braking, variable speed control and monitoring for PMSM in real time through administration program of Web-Based.

  • Embedded system area has brought an innovation and has been spread rapidly by the growth of the Internet, wireless telephony and multimedia recently. Many embedded systems are required to be real-time systems in that it needs multi-tasking and priority based scheduling. This paper introduces a real-time system that was developed with web server ability for control and monitoring system employing a real-time operating system. It discusses the design model, structure, and applications of web server system. We used SNDS100 board which has a 32-bit RISC microcontroller of ARM7TDMI core as a hardware platform. MicroC/OS kernel was used as Real-time operating system that supports a preemptive and multitasking functions. We developed a hierarhchical control and monitoring system that not only reduced system and management costs, but also enhanced reusability and portability.

  • With the rapid growth of internet infrastructure, World Wide Web is evolving recently into various services such as cloud computing, social network services. It simply go beyond the sharing of information. It started to provide new services such as E-business, remote control or management, providing virtual services, and recently it is evolving into new services such as cloud computing and social network services. These kinds of communications through World Wide Web have been interested in and have developed user-centric customized services rather than providing provider-centric informations. In these environments, it is very important to check and analyze the user requests to a website. Especially, estimating user preferences is most important. For these reasons, analyzing web logs is being done, however, it has limitations that the most of data to analyze are based on page unit statistics. Therefore, it is not enough to evaluate user preferences only by statistics of specific page. Because recent main contents of web page design are being made of media files such as image files, and of dynamic pages utilizing the techniques of CSS, Div, iFrame etc. In this paper, large log analyzer was designed and executed to analyze web server log to estimate web contents preferences of users. With mapreduce which is based on Hadoop, large logs were analyzed and web contents preferences of media files such as image files, sounds and videos were estimated.
