According to the increasing use of information in the mobile web environment, web information techniques previously developed considering only a specific platform become unable to use. Such techniques need to be replaced by the web standard techniques guaranteeing interoperability and to develop a new graphic user interface required in the mobile web environment. Based on such backgrounds, this paper surveyed the standards for implementing web geographic information system(GIS) service considering mobile and desktop environments. Based on the survey results, a GIS system configured with open source is designed and web mapping clients based on ExtJs are implemented for mobile and desktop environments. For the purpose of coping with the new web standard environment, the methods and prototype system suggested and implemented in the paper can be used as a case study to implement a GIS in the use of mobile and desktop environments.

Recently, it is to increase rapidly in people who do a private business through Web service. So, many companies have been developing part of businesses using Web Services. The greatest interest of companies developing Web Services was that users were easily discovering and using information on theirs. So, companies have been taking interest in a standard that supports registrations of information on Web service and discoveries of a registered Web services. Therefore UDDI 3.0 standard of the registry for Web service standardized by OASIS is in the spotlight. But, because of the complexity of it, there are no implementations developed in the inside of the country yet. And a development activity of it is faint. In outside of the country, IBM, Microsoft and SAP has developed it, but they do not perfectly support a standard of UDDI 3.0. This Paper shows the development of the Registry System which supports perfectly a standard of UDDI 3.0.

최근 3D 그래픽스 기술과 관련된 기기들의 비약적 발전을 통해 가상, 증강, 확장 현실이라는 기존의 현실 세계에 새로운 정보를 더하는 연구가 활발하게 진행되고 있다. 우선 앱 기반의 가상, 증강, 확장 현실을 구현하는 과정에서 기기별 또는 브라 우저별, OS별로 개발 환경이 다름으로 인한 개발비용이 상승하는 등의 애로사항들이 있었고, 이로 인해 Web 환경에서의 가상, 증강, 확장 현실을 구현하기 위한 표준형 통합 플랫폼의 필요성이 대두하였다. OpenXR, WebXR이 가상 증강현실에서의 새로운 표준을 제시하고 기술을 공개하여, 하드웨어와 소프트웨어 산업 모두에서 좋은 호응을 얻기 시작하였다. 따라서 본 고에서는 가상 증강현실에서의 OpenXR과 WebXR 표준에 대한 정의 및 기술에 대하여 살펴보고, 가상 증강 환경에서의 기술 동향과 발전방향에 대하여 살펴보고자 한다.

Recently, non-standard techniques of web like Active-X caused not only user inconvenience but also barriers to the business of Internet. The government recognized that the serious environmental situation of using Internet is needed to be improved. Especially, HTML5 convergence technology is meant to be a specific platform over the devices, users, and systems. It also means web standards to support more creative business service model and emerging market. In this paper, we performed a survey on Web standards compliance and web development professional level of domestic web developers. In addition, we present the basic direction of government policy of software and software-positive human resources policy, that is based on the analysis of the survey results. Our study will be able to contribute to construct policies to support digital convergence industry and to strengthen technical assistance and expertise to build training programs for the spread of global Web standards (HTML5).

Mobile web applications are being used and changed rapidly due to the growth of mobile device performance. But, cost of development environment and standards make the high development cost and low productivity. It is main reason that the design and implementation of the applications are more time consuming than general computing environments. In this paper, we propose MWeb(MobileWeb)-Framework based on the agile methodology and Ruby on Rails that is a kind of framework for supporting mobile web application development using mobile web standards. This work consists of the mobile web development architecture and agile process model. MWeb-Framework will support the same user experience to the different devices. We validates the framework by implementing the case studies through suggested mobile web development framework. As a result, we can develop the mobile web applications with productivity and quality. In the future, we will suggest how to make the MWeb-Framework standardization and practically apply the frameworks the various case studies to improve framework potentially problems.

As the Internet and mobile services increase, the use of wired/wireless web contents services increase and the demand for various contents explosively grows. To survive in competitive market, and to minimize the errors and warnings for web accessibility and standardization, and then to maximize the web usability, the periodical evaluation for web site should be performed with the events of web marketing and campaign. Through the web evaluation, the errors for technical programming language and contents offering can be found and diagnosed. In this paper, the quantitative and qualitative evaluation method for web site providing web contents are presented, and the analytic results for the 138 home pages in domestic are evaluated to validate the quantitative methodology. The accessibility, standardization, and usability factor are adopted for the evaluation in which accessibility is evaluated for perceivable, operable, understandable, and robust discipline with K-WAH(Korea-Web Accessibility Helper) tool, the standardization are measured for the number of errors and warnings in technical language with the W3C validator, and finally the usability factor is analyzed for the number of visits, average visit duration, and bounce rate with Google Analytics. In addition to, the quantitative analysis is also performed with the consideration of cost for construction and operation of web site. From the results, in the case of total score of 100 in conversion with relative weight, the average and standard deviation are evaluated to be 55 and 14, respectively. The correlation analysis indicates that the coefficient is estimated as 0.058, and then correlation between the quantitative results and cost is evaluated to be a little positive.

최근 차세대 Web 기술로서 Semantic Web이 주목 받고 있다. Semantic Web에서는 Web상에 존재하는 문서에 Web Resource들에 대한 Ontology를 기반으로 Semantic Annotation을 하고 Ontology 추론 Agent를 통하여 의미 기반으로 Web을 검색할 수 있도록 해준다. 이와 같은 Semantic Web 기술의 핵심 요소는 Web Ontology이며 W3C에서는 이를 표현 할 수 있는 표준 언어로서 RDF기반의 OWL(Web Ontology Language) 명세를 제정하고 있다. 따라서 표준 Web Ontology 언어인 OWL을 위한 추론 시스템은 Semantic Web 검색 Agent의 구현을 위한 필수적인 기반 기술이라 할 수 있으나 아직 그 개발이 미비한 상태이다. OWL 추론 시스템을 구현하기 위해서는 OWL의 이론적인 기반을 제공하는 DL(Description Logic)을 추론할 수 있는 엔진을 사용하는 것이 한가지 방법이 될 수 있으나 OWL이 Rule과 같은 DL의 범주를 벗어나는 Vocabulary를 지원하는 언어로 확장되는 경우에 이를 처리하기가 어렵다. 또 다른 방법으로서 Logic Programming을 통하여 OWL 언어의 Semantic을 기술하고 정리 증명(Theorem Proving)을 통하여 Ontology를 추론하는 공리화(Axiomatisation) 기법이 있는데 이러한 방법의 장점은 기반이 되는 Logic의 범주 내에서 새로운 언어를 위한 Vocabulary의 확장이 용이하다는 점이다. 본 논문에서는 Axiomatisation 방법을 이용하여 OWL로 기술된 Ontology를 추론할 수 있는 시스템의 설계 및 구현에 대해 설명하기로 한다.

Due to increase of interest in web accessibility and recognition of its necessity, a variety of accessibility indicators and automatic assessment tools have been developed, but previous literature indicated various problems about these indicators and tools. Thus, this research proposes and verifies the assessment model for accessibility of a frame content by considering web standards which develop the same web page for every client environment.

To achieve web application security goals effectively by providing web security features such as information leakage prevention, web application firewall system must be able to achieve the goal of enhancing web site security and providing secure services. Therefore, it is necessary to study the security evaluation of web application firewall system based on related standards. In this paper, we analyze the requirements of the base technology and security quality of web application firewall, and established the security evaluation criteria based on the international standards for software product evaluation. Through this study, it can be expected that the security quality level of the web application firewall system can be confirmed and the standard for enhancing the quality improvement can be secured. As a future research project, it is necessary to continuously upgrade evaluation standards according to international standards that are continuously changing.
