According to the statistics revealed by Bank of Korea on March, 2007, Internet banking transactions outnumbered face-to-face banking services in Korea. Internet banking is becoming essential in every financial service sectors. For people with disabilities, Internet banking is more meaningful because they do not need to visit the bank, thereby saving inconvenient trips. Governments in many countries are working on setting standards and laws on the web accessibility for people with disabilities. Korea government enacted Korea Disability Discrimination Act in 2007. This paper examined the web accessibility compliance of Internet banking sites. Twenty one Internet banking sites were selected from the list in the Korea Federation of Banks's Web sites. We examined four major checkpoints that are considered crucial among the fourteen checkpoints in "Internet Web Contents Accessibility Guidelines" which was amended by Ministry of the information and Communication in 2005. The results showed that all of the twenty one Internet banking sites didn't meet the four major checkpoint requirements. Moreover, only one banking site satisfied alt-text requirement that is considered the most fundamental among the checkpoints.

With the development of mobile and wireless environments, the Ubiquitous era has com on the base of technologies of Semantic Web and Web Services. To accelerate proliferation of the E-Commerce in the Ubiquitous era, the importance of information search is emphasized more and more and its time to need more intelligent search for product and service which can consider location and other context-aware related information. As a starting point to meet these requirements, we proposed more effective product information search service framework through web services under semantic web environment. Over the wireless internet and we also examined its technical validity with the prototype system, implemented prototype and investigated the technological possibility.

최근 웹 서비스(Web Service)와 웹 프로세스(Web Process)는 이기종 시스템의 통합과 웹 애플리케이션 배포를 위한 대안으로 주목받고 있으며, 이에 따라 웹 서비스의 QoS(Quality of Services)의 중요성도 증가하고 있다. 본 논문에서는 웹 서비스의 QoS 분석 방법을 제안하고, QoS 중심의 웹 서비스 조합 도구인 SimQom4W (Simulation-based QoS-aware Composer for Web Services)를 소개한다. SimQom4W는 첫째, 웹 서비스와 웹 프로세스의 구성을 시각으로 기술하고, 둘째, 웹 프로세스에 대한 테스트 코드와 시뮬레이션 코드를 자동 생성하여 실행시킴으로써 QoS를 분석한다. 셋째, 다양한 QoS 요구사항을 만족하는 최적의 웹 프로세스를 선택할 수 있도록 하며, 넷째, 웹 서비스의 QoS 분석 및 평가 데이터의 보고서를 생성하여 제공한다.

Web Services가 차세대 e-Business를 주도할 것으로 많은 주목을 받으면서 XML(extensible Markup Language)을 기반으로 하여 폭넓게 성장해 가고 있다. 하지만 안전한 서비스의 측면에서 Web Services 는 폐쇄환경에서는 존재하지 않았던 새로운 보안 고려사항들을 부각시키고 있다. 이에 대한 해결을 위해 본 논문에서는 XML을 기반으로 하는 Web Services의 특성에 맞추어, 플랫폼 독립적이며 언어 중립적인 특징을 유지한 XML-Signcryption을 제안하는데, 이것은 논리적으로 한번에 전자 서명과 암호화를 함께 수행하도록 하여 기존의 서명 후 암호화에서 요구되는 계산 비용보다 더 적은 비용을 가지고 있는 Zheng의 Signcryption 기법을 XML 보안에 응용한 것이다. 본 논문에서 처음으로 XML 구문 형식을 따라 XML-Signcryption이란 명칭으로 설계하여 제안하는 XML-Signcryption은 암호화와 전자서명을 따로 구현한 W3C(World Wide Web Consortium)의 XML-Encryption이나 XML-Signature 스펙과 비교해, 전자서명과 암호화의 두 가지 보안 메커니즘을 위한 각각의 구현을 따로 할 필요 없이 한번에 할 수 있다는 면에서 개발자들에게 편리성을 제공할 뿐만 아니라 계산 비용 측면에서도 효율적인 장점을 제공한다.

Several researches have been proposed to formalize the knowledge preconditions problem - j.e., an action or a plan is epistemically feasible. However, since the feasibility is only checked at design-time and is assumed that it will also 1)e feasible at run-time, it is not suitable in the context of Semantic Web services composition, where many agents should share the limited resources required for the execution of Web services composition. Therefore, in this paper, we formalize a transactionally executable Web services composition which enables to guarantee its atomicity. Moreover, in order to formalize the transactional executability, we propose $TL-ALCFK_{NF}$ which extends TL-ALCF with the modal operators K and A. Based on $TL-ALCFK_{NF}$, we show how to carry out the epistemic reasoning with TL-ALCF as a language to represent Semantic Web services composition.

Web services are standardized software technologies that enable interoperability of operating systems and programming languages through networks and related standards. Web services are distributed computing services that provide and discover services making it possible to access various services. Since the search method of web service considers only the functional aspect, it has a limitation on user-oriented search when selecting a service. In order to solve these problems, this study proposes an automatic IoT information generation tool, and provides IoT extension information when searching a web service, thereby improving the problem so that a suitable service can be selected for a user. Automatic IoT extension information generation tool proposed in this study collects and stores various information generated in the process of sensing, networking, and information processing by collaborating autonomously in a distributed environment of user, object, and service. The proposed method supports the service search suitable for the user by providing the information generated by the user as extended information when searching the web service. The proposed method can be applied to the 4th industry sector to provide a customized service that meets various environment requirements.

Test Case Prioritization (TCP) involves the rearrangement of test cases on a prioritized basis for various services. This research work focuses on TCP in web services, as it has been a growing challenge for researchers. Web services continuously evolve and hence require reforming and re-execution of test cases to ensure the accurate working of web services. This study aims to investigate gaps, issues, and existing solutions related to test case prioritization. This study examines research publications within popular selected databases. We perform a meticulous screening of research publications and selected 65 papers through which to answer the proposed research questions. The results show that criteria-based test case prioritization techniques are reported mainly in 41 primary studies. Test case prioritization models, frameworks, and related algorithms are also reported in primary studies. In addition, there are eight issues related to TCP techniques. Among these eight issues, optimization and high effectiveness are most discussed within primary studies. This systematic review has identified that a significant proportion of primary studies are not involved in the use of statistical methods in measuring or comparing the effectiveness of TCP techniques. However, a large number of primary studies use 'Average Percentage of Faults Detected' (APFD) or extended APFD metrics to compute the performance of techniques for web services.

Research records have become more important because of the increased significance of the preservation and use of such records. Therefore, many research institutions provide web-based research records archival information services. However, no evaluation of these research records services has been conducted, so problems arise that make discussing the current state of such services and their future improvement difficult. Therefore, this study evaluates web-based archival information services for research records and proposes ways to vitalize them. This study analyzes the characteristics of NTIS and NKIS, which are types of web-based archival information services for research records, and evaluates them using the same evaluation measures. Finally, this study recommends ways to improve web-based archival information services for research records.

The field of the web service orchestration introduced to generate a valuable service by reusing single services. Recently, it suggests rule-based searching and composition by the AI (Artificial Intelligence) instead of simple searching or orchestration based on the IOPE(Input, Output, Precondition, Effect) to implement the Semantic web as the web service of the next generation. It introduce a AOP programming paradigm from existing object-oriented programming paradigm for more efficient modularization of software. In this paper, we design a dynamic web service orchestration and invocation scheme applying Aspect-Oriented Programming (AOP) and Reflection for Semantic web. The proposed scheme makes use of the Reflection technique to gather dynamically meta data and generates byte code by AOP to compose dynamically web services. As well as, our scheme shows how to execute composed web services through dynamic proxy objects generated by the Reflection. For performance evaluation of the proposed scheme, we experiment on search performance of composed web services with respect to business logic layer and user view layer.
