The efficient test tool is indispensable to the test driven development. The test tool is very helpful to get the advantage of the test driven development. Many traditional automation test tool does not support standard script language and are not suitable to unit test. In traditional unit test tool, a code for the test is added at the source code. Such method makes the complexity of a source code and has a problem which must modify many part of the source code when the test case is changed. In this paper, we present a design technique of a flexible unit testing tool which makes a developer can modify easily the test case by using the standard java script in test driven development. We implement the test tool by this design technique to verify the availability of this technique.

In the monitoring system based on web service application, it is faced with the problems like code reproduction, difficult scalability and error recovery derived from the frequent change of data structure. So we propose a technique of monitoring system by DTD(Document Type Definition) automatic generation. This technique is to use dynamic server-side script to cope with the change of sensor data structure, generate the DTD dynamically. An it also adapt the AJAX(Asynchronous JavaScript and XML) for XML data parsing, it can support mass data transmission and exception processing for data loss and damage. This technique shows the result of recovery time is decreased about 44.8ms in case of temporary data failure by comparing to the conventional XML method.

XML 구조는 기존의 HTML의 단점을 보완한 SGML의 복잡함을 보완하고 호환성이 있다는 점에서 주목을 끌고 있다. SGML은 마크업 언어의 표준으로 등장했지만 규모가 커서 처리해야할 사항이 너무 많았다. 그리고 HTML은 단순하기는 하지만 사용자가 원하는 모든 작업을 수행하기에는 충분하지 못했다. HTML에 새로운 태그, JavaScript, VBScript와 같은 스크립트 언어들을 추가함으로서 이러한 한계를 극복하려는 시도도 있었다. HTML은 이러한 확장은 가능했지만, 너무 많은 회사들이 난립해 웹상에서 혼란만 초래하게 되었다. 이에 XML구조의 장점과 필요성에 대해서 짚어보았다.

Recently, Web map service is actively accomplished in both private companies and public offices. As a platform, it exists variously from desktop to smartphone. The technology being used has a trend to develop continuously. Also, Web map system provides various open API for people who use geospatial service and data mashup. In this paper, RIA technology which is popularly used recently in web map service w ill be applied to introduce the functions different language map services are mostly using. Based on users' feeling about different web browser's speed, test and analysis have been accomplished. The result is that there are different characteristics according to different functions such as JavaScript, Silverlight, Flex. Actual test has been personally carried out on map service in Seoul GIS portal system. The comprehensive conclusion is that Silverlight has more outstanding function compared with other RIA techniques under the test environment.

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.

In this paper, we design and implement a web-based courseware where learners can do self-directed learning to study Web programming languages such as Html, CSS, JavaScript and Dhtml. Each section consists of text class, movie class, practice class, formative assessment, laboratory and bulletin board. And our courseware makes teachers to teach, assess and give scores to learners on Web. In our Web courseware, learners can play a movie class and practice Web programming codes in one screen simultaneously, and execute codes and confirm a results in the same screen also. Therefore, learners can understand Web programming languages efficiently, which are hard to understand immediately by text.

As the use of Mashups, web3.0, JavaScript and AJAX(Asynchronous JavaScript XML) widely increases, the new security threats for web vulnerability also increases when the web application services are provided. In order to previously diagnose the vulnerability and prepare the threats, in this paper, the classification of security threats and requirements are presented, and the web vulnerability is analyzed for the domestic web sites using WVS(Web Vulnerability Scanner) automatic evaluation tool. From the results of vulnerability such as XSS(Cross Site Scripting) and SQL Injection, the total alerts are distributed from 0 to 31,177, mean of 411, and standard deviation of 2,563. The results also show that the web sites of 22.5% for total web sites has web vulnerability, and the previous defenses for the security threats are required.

XML was applied to web-Based application system for efficient data supervision and processing. Also, ASP permitted embodiment of easy web-Based programming, and UML is studied by the new alternative of system modelling techniques. Thus, In this paper see embodied student taking a course application management system using XML, ASP, UML. This was composed, and used XML for effective data supervision and processing by student mode and administrator mode. Also, It used UML for systems analysis and design, and whole system implemented by ASP. And, Database implemented to used in MS-ACCESS, and it used java Script language for efficient practical use of web document.

With the help of a small wearable device, patients reside in an isolated village need constant monitoring which may increase access to care and decrease healthcare delivery cost. As the number of patients' requests increases in simultaneously manner, the web service gateway located in the village hall encounters limitations for performing them successfully and concurrently. The gateway based RESTful technology responsible for handling patients' requests attests an internet latency in case a large number of them submit toward the gateway increases. In this paper, we propose the design tasks of the web service gateway for handling concurrency events. In the procedure of designing tasks, concurrency is best understood by employing multiple levels of abstraction. The way that is eminently to accomplish concurrency is to build an object-oriented environment with support for messages passing between concurrent objects. We also investigate the performance of event-driven architecture for building web service gateway using node.js. The experiments results show that server-side JavaScript with Node.js and MongoDB as database is 40% faster than Apache Sling. With Node.js developers can build a high-performance, asynchronous, event-driven healthcare hub server to handle an increasing number of concurrent connections for Remote Healthcare Monitoring System in an isolated village with no access to local medical care.

This paper deals with the design and development of the remote control and measurement systems by Embedded Web Server. The remote control and measurement systems are implemented by Cortex M-3 ARM micro-controller. The user application software for the control and measurement system user, and the firmware software of device drivers for peripherals such as a digital input/output device, AD/DAC(Analog to Digital/Digital to Analog Converter), LCD, and temperature/humidity sensor are developed in Eclipse environment using Codesourcery C, Java script, and HTML. The experimental result of the proposed control and measurement systems implemented in this paper is evaluated via real-time experiments, which works well as designed.
