Web-based analysis programs for reliability assessment of machine tools were developed in this study. First, the reliability data analysis program was developed to search for failure rate using failure data and reliability test data of mechanical part. Second, failure mode analysis was developed through performance tests like circular movement test vibration test for machine tools. This analysis program shows correlation between failure mode and performance test result. Third, tool life was predicted by correlation between flank wear and cutting time, using the extended Taylor tool life equation in turning data and the equivalently converted equation in order to apply ball endmill data to Taylor tool life equation in milling data. All the information related to input and result data can be stored in theses programs.

The desire of achieving abundant and various information in Web-sites through portable devices is increased as the mobile communication technology is matured. WML(Wireless Markup Language) is the fundamental language to fill up the those desires. The number of commercial WML sites which can be accessed by PCS(Personal Communication System) over the Internet are growing rapidly worldwide. In this paper, a WML authoring tool which can author easily the homepage suitable for PCS is designed and implemented. The usability of the proposed WML authoring tool was confirmed by using UP.SDK simulator over the Internet.

In recent years, a life phenomenon using a workflow management tool in bioinformatics has been actively researched. Workflow management tool is the base which enables researchers to collaborate through the re-use and sharing of service, and a variety of workflow management tools including MyGrid project's Taverna, Kepler and BioWMS have been developed and used as the open source. This workflow management tool can model and automate different services in spatially-distant area in one working space based on the web service technology. Many tools and databases used in the bioinformatics are provided in the web services form and are used in the workflow management tool. In such the situation, the web services development and stable service offering for a sequence similarity search which is basically used in the bioinformatics can be essential in the bioinformatics field. In this paper, the similarity retrieval speed of biology sequence data was improved based on a Linux cluster, and the sequence similarity retrieval could be done for a short time by linking with the workflow management tool through developing it in the web services.

The Learning Models including the design principle about web 2.0 use in education has been recently presented. In types of web 2.0 tools, blogs are the best tool that reflected the trends of web 2.0 and these are able to share a lot of information and contents. To invent new learning methods involving web 2.0, this study aims to get the results about effectiveness of learning performance on a supplementary learning tool based on blog using learner-centric UI/UX design in higher education. As a study tool, installation-type blog that can be designed as user-centric system is applied to experimental environment. This study presents the conclusion that supplementary learning tool based on blog using learner-centric UI/UX design influences on learning achievement and learning flow through the analysis of questionnaire results of learners, learning evaluation score of learners and assignments evaluation score of learners.

Nowadays, we can easily access a remote database as well as a local database with HTML forms. Although implementing a database application with HTML forms is much simpler than implementing it with a proprietary graphical user Interface system, HTML forms and CGI programs still must be coded. We implemented a software tool that automatically generates the SQL statements that create a database for an application, the forms that are used as a user interface, and the Java servlets that retrieve the data requested through the forms. The database tables to be treated and the forms to be generated are determined by the class diagram for the application. Our software tool, which we call WebSiteGen, thus simplifies the implementation of a Web-based database application.

Current web search includes a lot of different results with information that user does not want, because it searches information using keyword mapping. Ontology can describe the correct meaning of web resource and relationships between web resources. And we can extract suitable information that user wants using Ontology Accordingly, we need the ontology to represent knowledge. W3C announced OWL(Web Ontology Language), meaning description technology for such web resource. However, the development of a special tool that can effectively compose and edit OWL is inactive. In this paper, we designed and developed an OWL authoring system that can effectively provide the generation and edit about OWL.

Feature models are widely used to model commonalities and variabilities among products during software product line development. Feature configurations are generated by selecting the features to be included in individual products. Automated tools to identify errors or inconsistencies in the feature models and configurations are essential to successful software product line engineering. This paper proposes a verification technique and tool based on semantic web technologies such as OWL, SWRL and Protege API. This approach checks the feature model and configuration based on predefined rules and provides information on existence of errors as well as the kinds of those errors. This approach is extensible due to ease of rule modification and may be easily applied to other environments because semantic web technologies can be easily integrated with other programming environments. This paper demonstrates how various semantic web-related technologies can support automatic verification of one kind of software development artifact, the feature model.

Web-based instruction is being developed as a new study model getting out of the traditional standardized education method. It is a new education tool which promotes learner-centered and cooperative study. Flash, as one of the most powerful web authoring tool can maximize the effectiveness of learning using computer graphic, animation, sounds and video. In this paper, we will look at developing and distributing education materials using flash and the efficient web-based instructions.

Reference resources management tools can be divided into three types: Desktop-based, Web-based, and Web 2.0-based. This study is intended to compare and analyze the functions provided by the three types of tools and also to compare and evaluate their usability. Each Tools were chosen to represent each type. For comparison and analysis of the functions provided by the three types of tools, we divided the process of using reference resources management tools into four steps and then compared and analyzed sub items in each step. Satisfaction, understandability, conformance and efficiency that items for comparison and evaluation of the usability were compared using both quantitative and qualitative approaches. We surveyed the participants to collect data for quantitative research; and interviewed them and analyzed the results for qualitative research. Here are the results from evaluating the usability of Tool A(Desktop-based), B(Web-based), C(Web 2.0 based). First, Tool B had the highest mean user satisfaction, followed by Tool A and Tool C. Secondly, Tool B had the lead in understandability, followed by Tool A and Tool C. Thirdly, Tool A had the highest mean conformance, followed by Tool B and Tool C. Fourth, Tool B had the highest mean efficiency, followed by Tool A and Tool C.
