This paper introduces technical methods to improve the accessibility and usability of a WebRTC video conference (VC) application. Simplified login is essential, by applying such as single sign-on (SSO) to improve the accessibility of VC applications. High usability and manageability are also necessary to attract more users, enhance user experiences, and save service management cost. The proposed VC application leverages SAML-based federated identity management (FIM) to enable higher service accessibility. Users can access the application with their organizational ID and SSO authentication. The FIM eases user ID management and indirectly strengthens privacy information protection. Proposed web application has high usability and manageability because users and/or administrators can easily create, join, monitor, or tear down VC sessions through RESTful web service (REST API). We verify the feasibility of the VC application after illustrating the SAML-based identity federation and the designed REST API.

The purpose of this study was to develop, apply and evaluate the teaching learning plan for disabled experimental activity to evaluate the accessibility of middle school experimental facilities. Three main resources such as 2 hours teaching learning plan for disabled activity, recording sheets and evaluation sheets had been developed. The process plan had been applied 214 senior students in 7 middle schools purposely selected by areas, constructed years, number of stories of school during November to December, 2005. General accessible levels of middle school facilities was somewhat inadequate especially exterior slops, toilets, bowls were the most unaccessible ones. Most of all students had accidents and/or injuries in school environments from minor to major ones. Male Students were more likely than female Students to get injuries. Students experience of accidents and injuries and awareness of inconvenience, danger, needed facilities supported. the result of the accessibility levels evaluated by disabled activities. Students were generally satisfied with and positive to the teaching learning process plan developed and applied in this study. Students had improved critical Perspectives as well as awareness of inaccessible chances in the school facilities through the experimental process. The evaluation as differed by school characteristics and students' interests in disability.

The purposes of this paper are to find the effects of beauty shop online motivations on the convenience of reservation system, to investigate the convenience of reservation system on satisfaction, and to determine the effects of satisfaction on word-of-mouth behaviors. Based on the results, there are three factors in the motivations: diversion, service-prioritized, and impulse-driven tendencies. Also, there are five factors in the reservation convenience perception: efficiency of decision-making, easy monetary transaction, overall convenience, accessibility, and effortless nature of rewarding system. In terms of the convenience of online booking, the access convenience was found that as the motivation diversion and the service-prioritized motivation higher and as the impulse reservation motivation lower. Furthermore, this paper concludes that offered by online beauty service reservation systems, and higher satisfaction rate leads to higher review behaviours.

Library website is medium for connecting library information resources and users. However, searching and accessing methods to information resources in library websites and retrieval systems are mostly designed for users. So, the disabled users have difficulty accessing and using library information resources through library websites. Therefore, the author carried on current status study and analysis on the retrieval system of the national and public library websites in Korea. And then, the author proposes improvement plan in order to enhance satisfaction with information needs of disabled users and to use a basic study for construction of retrieval system of library websites for disabled users.

The purpose of this study is to present the direction of faculty's perception and direction of spatial composition to apply universal design principles to the space of kindergarten facilities. Based on previous research and literature review on kindergarten area, kindergarten facility space, and universal design, the universal design principle which was applied to the composition of kindergarten amenities derived four types of functional supportability, receptivity, accessibility and safety. In addition, the survey was conducted on kindergarten teachers and teacher assistants and the managers of kindergarten. As a result of the awareness of kindergarten facilities space, we have discovered the degree of universal design awareness.

최근 분산자바기술의 발전에 따라 다양한 애플리케이션의 단위기능들은 어디서나 호출 가능한 서비스로 정의되고 있으며, 또한 이러한 서비스들은 새로운 애플리케이션을 구성하기 위한 단위기능으로 사용되고 있다. 특히 RMI, CORBA 등은 가장 널리 활용되고 있는 원격 메서드 또는 서비스 호출 프레임워크로 분산 자바애플리케이션 개발을 위한 중요한 기술이라 할 수 있다. 그러나 이러한 기술들은 모두 원격메서드 또는 서비스의 호출을 위해 클라이언트사이드에서 스텁을 활용하는 기술로, 스텝의 정적생성 및 동기화 필요성으로 인해 다소 사용자 편의성 및 서비스의 접근성이 저해되는 측면이 있다. 따라서 본 논문에서는 이러한 스텁의 생성이 필요 없는 비스텁 방식의 효율적인 원격자바메서드 호출기법을 제시한다. 이 기법을 활용할 경우, 사용자 측면에서 별도의 스텁 없이 원격지의 서비스를 자유롭게 호출할 수 있어 사용자의 편의성 및 서비스 접근성을 크게 향상시킬 수 있으며, 원격 서비스 변경에 따른 동적 서비스 재구성 또한 지원할 수 있어 보다 유연한 애플리케이션 개발이 가능하다.

The current URLs are assigned per website so that a user must access the website to utilize specific contents resources. Considering that users are more interested in the resources than the website itself, the current URL is limited in terms of user convenience. This paper proposes a new model for contents location that is easily recognizable as web resources such as digital contents and can be accessed directly. It is expected to contribute to establishing standard infrastructure in contents distribution and better user convenience.
