In this paper, we implemented medicinal plant information system based on user requirement using Ajax technique which can retrieve data from the server asynchronously in the background without refresh webpage and jQuery which is a lightweight cross-browser javascript library. Also, we presented the source code handling the server response data used in the system and compared the features by the type of response data. This system shows the improvement of user interaction and response rates because of a simple response data from the server, client-side data processing and change of web page by manipulating the DOM tree and provides ease of use and convenient data access.

종래의 웹 기반 업무 협업 및 프로젝트 관리 방법으로 제공되는 기술은 ActiveX 나 JVM(Java Virtual Machine)을 이용한 특정 프로그램 설치를 통한 방법으로써 특정 플랫폼이나 브라우저에서만 동작하는 방법을 제공하고 있다. 본 논문에서는 통상적인 웹 기반에서 임의의 프로그램 설치 없이 Ajax(Asynchronous Javascript And XML)를 이용하여 웹 기반 업무 협업시스템을 개발하였다.

The web server for the embedded Linux system(ELS), unlike the ones for the usual Linux or Windows, has some disadvantages such as small number of installable applications, low compatibility and limited extensibility. This fact raises some problems when data are transferred in real-time via the web server, which are mainly caused by a poor performance of the processor and small-sized memory. Conventional user interfaces adopted for the usual web servers are unsuitable for the ELS because they are platform-limited and their installations are done by the form of plug-ins. If the web server for the ELS has an Ajax engine that can be utilized without any installation procedure, the advantages of usability, accessibility and quick response time can be obtained. This paper presents the Ajax interface for the ELS web server. The efficiency of the proposed technology in the real-time remote monitoring is shown through an implementation.

Web page evaluation is important issue in the Internet. Web pages are increasing extremely fast. The web page evaluation based on frequency, like the count of the page view (PV), is not sufficient way even it is used variously. Because users never use the unnecessary or irrelevant web pages for a long time. We concentrated on user's visiting duration time for the evaluation web pages. And we can collect user actions. Users do some action when users using the web page in the web browser. The movements of mouse pointer, mouse button click, page scrolling and so on are produced in the web browser. JavaScript can collect user action and Ajax can send collected data to server when user using the web browser without no user notification.

Recently, variety Web applications which is used Web2.0 are being developed and serviced. In this paper, we implemented Schedule Management Program for the individual and group based on Ajax applications, which apply the MVC design pattern with Java Servlet in order to complement Schedule Management Program which is developed with server-script languages. Also, we improved utilization of applications to provide various additional service through mash-ups built by combing APIs.

Nowadays, according to rapid development of computing environments, information processing and analysis system are very interesting research area. As a viewpoint of data preparation-processing-analysis in knowledge technology, the goal of automated information system is to satisfy high reliability and confidence and to minimize of human-administrator intervention. In addition, we expect the system which can deal with problem and abnormal error effectively as a fault detection and fault tolerance. In this paper, we design a monitoring system as follows. A productive monitoring information from various systems has unstructured forms and characteristics and crawls informative data by conditions and gathering rules. For representing of monitering information which requested by administrator, running-status can be able to check dynamically and systematic like connection/closed status in real-time. Our proposed system can easily correct and processing for monitoring information from various type of server and support to make objective judgement and analysis of administrator under operative target of information system. We implement semi-realtime monitering system using AJAX technology for dynamic browsing of web information and information processing using XML and XPATH. We apply our system to SMS server for checking running status and the system shows that has high utility and reliability.

The Web is widely used to share information, utilizing the client-server model. In the client-server model, since the server only responds according to explicit requests from the client, the model seems hard to support sharing of massive information rapidly changing in today's Internet. The technology known as Server Push enables the server to actively provide information to clients without explicit requests from the clients using Web pages. Although various studies have been done to realize the Server Push technologies, there are many problems in the development of push application without push engines which support infrastructures for the effective development of push application. In this paper, we develop JPE(Java Push Engine) which presents the effective support for push services over the Internet. JPE is composed of two main components: the JPE Core supporting Epoll and the JPE Library supporting asynchronous communication. In addition, JPE defines various push functions and provides programming interfaces supporting the functions. Push applications developed using JPE effectively manages client connections with Epoll mechanism, providing push services through AJAX-based asynchronous communication.
