The aims of this study are to develop web-based learning materials for science and environmental education of elementary school. The effect of environmental education was divided into eight to measure: the awareness of using web as environmental material, the ability to use web as environmental material. the awareness of environmental problems, the satisfaction for environmental education using web, the awareness of preserving local environment, self-leading ability to learn environment, the effect of using environment homepage, and the internalization of environmental awareness. This study obtained the following results; First, as a result of post-test, the average of the test group of web-based learning was 1.29 points higher than the control group having traditional learning in the awareness of using web as environmental material, showing a statistically significant difference. Second, as a result of post-test, the average of the test group of web-based learning was 2.80 points higher than the control group in the ability to use web as environmental material, showing a statistically significant difference. Third, as a result of post-test, the average of the test group of web-based learning was 1.10 points higher than the control group in the awareness of environmental problems, showing a statistically significant difference. Fourth, as a result of post-test, the average of the test group of web-based teaming was 0.89 points higher than the control group in the satisfaction for environmental education using web, showing a statistically significant difference. Fifth, as a result of post-test, the average of the test group of web-based learning was 1.70 points higher than the control group in the self-leading ability to learn environment, showing a statistically significant difference. Sixth, as a result of post-test, the average of the test group of web-based learning was 1.21 points higher than the control group in the effect of using environment homepage, showing a statistically significant difference. Finally, as a result of post-test, the average of the test group of web-based learning was 1.39 points higher than the control group in the internalization of environmental awareness, showing a statistically significant difference. Based on these results, it is assumed that the teaching method which applied web-based teaming to science and environmental education in elementary school is a effective strategy for elementary science and on environmental education.

As information and business communication via Internet are growing up, web-based software is wide spread and more important on the viewpoint of software qualify than stand-alone. Research on verification of web content links and web-based Program was tried, but has short on covering various types of web based software and making experiments to be applied in real testing practice. This paper suggests a modeling technique to be applied to dynamic and various types of web-based software. First, it identifies each elements consisting of web-based software and then construct a model of Object Control Flow Graph and Object Relationship Diagram. We can generate test cases covering all test paths of ORD or invoking key points test route. Suggested modeling method and test case selection technique are verified by applying five types of web-based software and compared with other web-based test techniques.

A web application is implemented by reusing the library provided by framework and has hierarchical architecture. Also, to deal with the user request from a screen, the web application has an execution flow, called 'Business Logic', which starts with a screen, executes its composed component and comes back to the screen via database. To test web application effectively, it should reflect the characteristics of web application. In this paper we propose to test web applications via user screens with the black-box testing approach and verify its source codes with the web interface white-box test coverage that covers all the business logics of the test target and their corresponding interfaces. We analyze the proposing testing method through its tool: Testopiacov.

In this paper, we propose a testing method of the quality of device application effectively reflecting the necessity of increasing mobile device application quality test, and designed and developed it as a web system. We have studied traditional software testing methods for designing and developing a system. We have developed a next-generation alternative technology that can analyze and compensate for the weaknesses of the web and weaknesses of the Android in order to realize the access system and the responsive web system. As an example applied to the system, we analyzed the requirements of the system implementation and expressed the functions of the system through the use case diagram. The test scenarios were conducted by connecting 5,000 devices to each system using the existing HTTP polling method and the proposed web socket method. After setting the comparative group, the result of the proposed web management system was observed and compared through repeated tests. The research shows that the proposed web socket system has better performance than HTTP polling. The more the number of simultaneous processing of the devices, the lower the server stability but the better the time efficiency. In conclusion, the more the number of devices to be tested is, the more the number of devices can be effectively tested using the proposed web management system.

Of critical importance to the success of any e-commerce site are the two factors: rapid application development and quick response time. A three-tier architecture composed of presentation layer, business layer, and data access layer emerges to allow rapid changes in user interface, business logic, and database structures. Too often, such a logical three-tier architecture is considered as requiring a three-tier physical architecture: Web server, application server, and database server running on separate computers. Contrary to the common belief, a Web stress test reveals that the three-tier logical architecture implemented on a two-tier physical platform guarantees a quicker response time due to the reduction in cross-machine communications. This would lead business firms to economize their spending on e-commerce: increasing the number of physical servers to expedite transaction is not necessarily the best solution. Before selecting a particular hardware configuration, a Web stress test needs to be conducted to compare the relative merits of alternative physical architectures. Together with capacity planning, Web stress test emerges as a powerful tool to build robust, yet economical e-commerce sites.

With greater utilization of web application and growth of its market, the function of such application is being expanded With today's increasing demand for high quality software, we see a sharp rise in the interest for web application test. The current trend is that web applications are being developed based on a framework of developmental environment. Hence, as the scope of that framework expands, each module of the entire web application is being configured by the combination of heterogeneous files. The distinctive characteristics of a web application are based on the fact that the framework that is provided in partially completed form controls the structure of all objects of development. The present study defines the web business logic as a minimal unit which has meaning as a unit of application for the web application. In this paper, we define web business logic as a least meaningful execution unit of web applications, propose how to generate automatically the BizUnit test code for it, and analyze the effectiveness of testing of the web application via the BizUnit test codes.

Recently web applications have growl rapidly and have become more and more complex. As web applications become more complex, there is a growing concern about their quality. But very little attentions are paid to web applications testing and there are scarce of the practical research efforts and tools. Thus, in this paper, we suggest the automated testing methods for web applications. For this, the methods generate an analysis model by analyzing the HTML codes and the source codes. Then test targets are identified and test cases are extracted from the analysis model. In addition, test drivers and test data are generated automatically, and then they are depleted on the web server to establish a testing environment. Through this process we can automate the testing processes for web applications, besides the automated methods makes our approach more effective than the existing research efforts.

The systematic testing is frequently regretted in recent web applications because of time and cost pressure. Moreover developers have difficulties with applying the traditional testing techniques to testing web application. The approach of creating test cases for a web application from a sequence model is proposed for the rapid and efficient testing. Test cases for web application are extracted from call messages (including self-call messages) of UML (Unified Modeling Language) sequence diagram. A test case consists of messages, script functions, or server pages and additional values. Moreover a simple testing tool for web application is proposed. A URL for testing web application is created and executed by this testing tool. The URL consists of server page address and additional values. This test tool is made using Microsoft Visual Basic. The efficiency of proposed method and tool has been shown using a practical case study which reflects the development project of the web application for supporting member management.

The aim of this research was performance of Web-based real time DGPS using MS visual basic 6.0 Active X control. This system supported the navigation of rover by transmitting the DGPS correction information of base station via internet and monitored the moving of rover by displaying the corrected results received from rover as well as permitting Web users monitoring for rover. The Web-based DGPS server and the client system using MS visual basic 6.0 Active X control for DGPS displayed on Web-browser with the pre analysis was constructed and the system loading test via Web-browser was performed after debugging this system through the static GPS test and publishing it on Web. Also, the wireless internet DGPS test on Web by changing the distance between a base station and a rover was carried out. As the result of the test, the real time DGPS could be performed by transmitting the correction message which calculated from the server system to the client system continually. The rover could be managed by displaying the location information which received from the client system. Other users also could monitor the rover by connecting with this system via internet in real time.

Vocational rehabilitation is defined as a process which helps people with disabilities to maintain life of non-disabled people and vocational assessment is a part of it. Traditionally, vocational assessment is performed through using of assessment tools, vocational counseling and so on. It is very efficient to apply vocational assessment to people with disabilities using the internet, but we should provide them with web accessibility. In this paper, we design and implement the aptitude test system for people with visual impairment supporting web accessibility. We develop the aptitude test system using the Holland Test which is the assessment tool of career guidance and counseling. We also show that the aptitude test system for people with visual impairment supports web accessibility more than previous Holland Test which is served in the internet.
