Real-time video communication technology of hybrid Web-based using JavaScript and HTML5 today is on the rise. Therefore, in this paper, we have studied the real-time videoo communication technology using a Web browser that supports HTML5. It has been designed and implemented a system based on HTML5 and JavaScript, allowing for video communication of real-time, such as you would using the HTTP/WebSockets and RTC API through the Web servers in the Web browser between different each other, utilizing a Web browser was. It is available in a usable terminal equipment of a Web browser PC or notebook, smart pad, such as a smart phone, which is available without installation, such as a plug-in register or another. In all environments the network is connected, it is available in all terminals use the Web browser is enabled, which will be utilized in the field of video communication in a restricted environment.

This paper is concerned with the development of web-based engineering calculation program using Javascript. Recently, various techniques are developed based on the advance of the internet environment. The Javascript can be used in the client PC without any interpreter which is necessary in Java. Simple formula can be easily constructed using the Javascript and the results can be readily available without any playing. In this study, we demonstrated the method of constructing engineering web useful for engineers.

A monitoring system for the security is increasingly demanded in line with the issue of the infringement of privacy. This paper has conducted the study on the monitoring technique via the Internet using PC or PDA. This is a monitoring system for web-camera based home server, which transmits the images and sound data captured by mike-embedded USB camera, though multiplexer of H.263 and internet. It integrates the operating processors of each device into a unified drive module and provides it the operator to facilitate the system operation and maintenance.

Recently, factory automation and shop floor control system need a web based remote monitoring technology to control effectively machine tool. This paper describes a web based remote monitoring system which is concerned with open architecture controller for machine tool. The environment of this system consists of a lot of elements such as web server, database, machine tool, pc based controller, client computers and script programs, also which is interconnected by network including intranet or internet. Designed script programs, also which is interconnected by network including intranet or internet. Designed script program service current status and faults information of machine to remote users who want to monitor machine tool. Additionally those have various functions to service we board for q&a, downloading data and information of after-service managers.

After launched various smart devices such as smart phone and tablet PC, people who using smart devices are provided various services. Especially, contents sharing technology is utilized in any devices. But current contents sharing systems are made on various versions for various smart devices. These methods will be raising cost for development of application. Therefore it must using web technology for reducing cost. In this paper, we had analyzed performance of file transmission using web technology and compared with application based system.

This paper proposes a method of constructing of hybrid web-based smart learning system to operable in a variety of mobile devices. To do this, the proposed system is developed a learning system with standardized and enhanced functions. In the proposed method, API specifications based on the standard functionality of smart learning system are created. And then, by building the API provider on a legacy system an organic linkage between the legacy system and the smart learning system is guaranteed. A standard API method is applied to data integration between the PC-based learning system and the smart learning system. The smart learning system interacts with legacy learning systems though Json/XML data forms via the https protocol. As a result, the legacy system using the proposed method dose not require major modifications and changes for a smart learning service.

In recent days, pc can process many things that mainframe have processed. Especially, in the transition from mainframe to pc, industries have needed the capabilities of Real Time information processing and Real Time monitoring for information control. But to support Real Time properties, it's needed to add Real Time modules and verify them. In this dissertation, we implemented and verified the Real Time System to support Real Time property. In addition, we implemented Web-based Real Time Monitoring System for Real Time information monitoring.

Intranet system for use within an organization, usually a corporation, is to basically pass through user authentication, but information can be leaked, modified, and deleted by malevolent users who disguise an authorized user or due to user's mistakes in using various functions of web browser. Thus, there is a need for measures to protect the information from illegal use, transformation through partial modification, and illegal leakage such as fraudulent use. This paper presents a flexible Web Security Access Control system based ACM which Provide efficient suity Policy to Protect information in intranet. This Web Security Access Control system not only enhances security by Performing encryption/decryption of information in intranet but also, for sharing confidential information among departments, performs effective and useful access control by assigning different authority to the secured web page. And, by controlling the functions of client PC in various ways, information leakage on malicious purpose or by mistake can be prevented.

An operating system acts as an intermediary between your computer hardware and computer users to perform, that the user can run the program provides an environment in which. Therefore, the main purpose of the operating system having a computer available for your convenience and to effectively manage computer hardware. The popularization of the people who use computers, improve hardware performance, advent of the internet, popularity of wireless networks, Smartphone and Tablet PC appearance, advent of virtualization technologies and cloud computing, etc. began making changes to the operating system. In particular, cloud computing environments based on server virtualization and using a variety of wired and wireless devices with internet connection, a Web-based operating system was born. In this paper, the definition of a Web-based operating system, types and characteristics, an analysis of the pros and cons, and find out about the future prospects.

As digital contents are widely used and require increasingly high quality, the data storage services over Internet also become more and more important. One of popular services, web-hard, provides lots of users with web-based functions for data storage, management and sharing but such storage utilization requires quite high cost compared to using portable storage devices. Moreover, some users may avoid putting their important data into open Internet area. On the other hand, portable storage devices are cheaper but can be used only when they are physically connected to host devices such as PC. Also additional management and security functions should be equipped to support data sharing among users. In this paper, we propose a web-based data storage system combining those advantages of aforementioned two approaches. The proposed system immediately provides web-based services for data management and sharing when a portable device such as SDD is connected to the server.
