The objective of this research is to evaluate the web standard as well as web compatibility of English homepage of tourist information manage local government. Thru this research, effective information and service can be provided to increasing foreign visitors and compatibility of English homepage can be strengthened. SortSite, a web compatibility measurement tool and UNICORN, a web standard measurement tool were utilized for this research. Chrome, Internet Explorer, Firefox, Safari and Opera were targeted for evaluating web compatibility and observance rate of Markup grammar and CSS grammar was checked for evaluating web standard. Research result showed that 46.7% of Chrome version ${\leq}34$ and 35 didn't observe the web compatibility while 95.6%, 53.3%, 53.3%, 53.3% and 55.6% of Internet Explorer version in order of 7.0, 8.0, 9.0, 10.0 and 11.0 didn't observe the web compatibility. Concerning Firefox, 75.6% and 48.9% of version in order of ${\leq}6.0$ and 7.0 didn't observe the web compatibility and 37.8% of Opera version ${\leq}12.17$ and ${\leq}21$ didn't observe the web compatibility. Regarding the web standard, 80% of English homepage didn't observe Markup grammar and 60% of them didn't observe CSS grammar. Therefore, urgent improvement of web compatibility and web standard is required.

Today, Web Services is very well-known as a middle-ware that can inter-communicate between many different program languages. This paper test web services by implementing two different web services platforms which are MS .NET based server and Apache AXIS based client. Those platforms have different data structure/process, and they could not give the developer seamless data compatibility through web services. However we confirmed that handling data, by some data transforming rules, web services can successfully inter-communicate between MS .NET based server and Apache AXIS based client.

The implementation of Internet based on EDI has become a major issue because of the huge development of the internet. Internet EDI is a technology which combines the strength of EDI and Internet technologies and it can be classified in FTP-EDI, SMTP/MINE EDI, and Web EDI. Recently, the number of companies which are adopted Web EDI increase to overcome shortcomings of high communication costs and high foundation and maintenance expenses of VAN EDI. This research is intended to examine the effect that characteristics of innovation and partnership as relationship with trading partner will affect the Web-EDI implementation. To achieve these purposes, we surveyed people who are in charge of Web EDI in their companies. A survey questionnaire was sent 376 people in charge of Web EDI in their companies, and 66 usable responses were obtained. The results of this research can be summarized as follows. First, it's affirmed, among partnership factors, that participation and interdependence significantly affect Web EDI implementation. It's also suggested, among innovation factors, compatibility, relative advantage, and cost reduction significantly affect Web EDI implementation.

UDDI is the open standard for distributed Web-based registry standard which supports registrations and discoveries of Web services. Recently, UDDI version 3.0 specifications were opened by OASIS UDDI Spec, technical committee. UDDI version 3.0 supports many useful functions, which are not supported in version 2.0 specification, such as nested query, enhanced find qualifiers, digital signatures subscription, etc. Despite of its merits, complexity of the standard and backward-compatibility support makes it difficult to adopt this standard in real application domains. In this paper, we develop the Registry server which support UDDI version 3.0 standard. This server is based on common RDBMS and it supports all functions of UDDI version 3.0 including backward-compatibility with version 2.0 API, XML digital signature and URI- based key schemes.

In this paper, we study the data interoperability problem of web services in terms of XML schema compatibility. When Web Service A sends XML messages to Web Service B, A is interoperable with B if B can accept all messages from A. That is, the XML schema R for B to receive XML instances must be compatible with the XML schema S for A to send XML instances, Le., A is a subschema of B. We propose a formal model called Schema Automaton (SA) to model W3C XML Schema (XSD) and develop several algorithms to perform different XML schema computations. The computations include schema minimization, schema equivalence testing, subschema testing, and subschema extraction. We have conducted experiments on an e-commerce standard XSD called xCBL to demonstrate the practicality of our algorithms. One experiment has refuted the claim that the xCBL 3.5 XSD is backward compatible with the xCBL 3.0 XSD. Another experiment has shown that the xCBL XSDs can be effectively trimmed into small subschemas for specific applications, which has significantly reduced the schema processing time.

As use of internet gets increased, the efficiency of applying the chart which is expressing and providing information through web is increased. The chart has the high delivering ability of information because it expresses data visually. But there are problems such as compatibility between the chart composing programs, difficulty of sharing the chart data, and displaying the chart on the web. In this paper, we propose the chart markup language, which expresses the chart information by using the XML in order to solve problems of compatibility of the chart expression and sharing the chart information. The CML is possible not only to provide compatibility between platforms and programs but also to share the chart data as it is based on the XML.

Among interactive dynamic geometry softwares, Cinderella has some merits on the accuracy of algorithms and compatibility with internet. In this paper we compare dynamic geometry softwares such as GSP, Cabri II, Cinderella briefly and we design a web based interactive learning materials using the exercise editor of Cinderella and some Java applets, and we propose a web based interactive teaching and learning model in which achievement test can be given by the clickings on the help icon.

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.

Due to advances in information technology, even Engineering Simulations can now be performed in web-based JAVA through an integrated operating system called Virtual Machine and the use of byte code, which guarantees the compatibility of identical codes in every computing system and makes it suitable for web-based simulation system development. This paper introduces an implementation embodied in JAVA Applet that allows a block-diagram type GUI that runs in a web browser for use in the dynamics simulation modeling of powertrains of vehicles and multi-body systems. This system is not restrained by any of the H/W and S/W in the user's computer, so that it has the advantage of providing a GUI that allows web-based block-diagram type modeling.

The Web Services descriptions such as DAML-S/OWL-S, BPEL4WS and WSMF focusing on the functional aspects of Web Services have limitations for the representation of the conceptual and semantic capabilities of Web Services, although WSMF is based on ontology and can represent the goal of Web Services. This paper proposes the new description formalism based on the competence ontology that can represent both functional and semantic aspects of Web Services. This paper also presents the integration and the composition of Web Services by means of Data Mediator(D-Mediator) and Control Mediator(C-Mediator) to mediate compositional in compatibility between heterogeneous Web Services.
