  • The library is a social institution that should ensure all users' information access rights. In this study, the concept of universal design is analyzed as a theoretical basis that library Websites should be accessed equitably by all kinds of users, and an evaluation criteria is developed based on the principles of universal design. The Websites of 7 regional central libraries are evaluated with suggested criteria and the ratio of compliance of universal Web design is measured. In the result, the most of the Websites are showed not only high performances on the area of (1) Web accessibility and (2) usability, but low performances on the area of (1) equitable use and (2) flexibility in use.

  • The initial research of Task Computing in the ubiquitous computing (UbiComp) environment revealed the need for access control of services. Context-awareness of service requests in ubiquitous computing necessitates a well-designed model to enable effective and adaptive invocation. However, nowadays little work is being undertaken on service access control under the UbiComp environment, which makes the exposed service suffer from the problem of ill-use. One of the research focuses is how to handle the access to the resources over the network. Policy-Based Access Control is an access control method. It adopts a security policy to evaluate requests for resources but has a light-weight combination of the resources. Motivated by the problem above, we propose a universal model and an algorithm to enhance service access control in UbiComp. We detail the architecture of the model and present the access control implementation.

  • The Broadcasting Law amended in January 2007 declared to adopt universal right to view(known more widely as Universal Access Right, UAR), the right to access broadcasting programs on such major sports or other events that are likely to catch the gaze of the public television viewers. Then its implementation rule was issued in February 2008, and under the regulations the Committee of Ensuring Universal Access Right has been established, where detailed action measures and guidelines are currently in the process of preparing. However, it is no question that an effectiveness of the implementation system of Universal Access Right presupposes sufficient amount of discussion and social consensus. At present, the major focus in this issue is on the matters including which type of events is subject to UAR and what criteria are desirable in determining which broadcasting company has priority. In this context, this study aims at identifying implications for policy by examining the precedent cases of Europe, Australia, and other countries, where UAR is enacted and implemented. Further, this study tries to draw up a specific scheme for ensuring universal right to view through conducting a survey on public television viewers. We will include specific guidelines for selecting events of public attention, criteria for selecting broadcasting companies regarding priority, and relevant operating rules regarding relayed broadcasting.

  • Purpose: Mobility impairment persons are all people who experience mobility difficulties in their daily lives, which makes up about 30% of the population in Seoul Metropolitan City; this number is expected to increase with population aging. As the number of mobility impairment persons in need of vision correction increases, it is necessary to create the Universal Design guidelines and to provide the foundation to access convenience facilities at the entrance of optical shops, a health and medical institution. Methods: Of the 2,282 optical shops located in Seoul, 252 optical shops were chosen for data collection of actual photos, from April 10, 2022 to September 4, 2022. Based on the photographs, the height difference between the entrance and the sidewalk, safety handles, and opening and closing methods of entrances were investigated, as these factors correspond to the accessibility and the mobility of the mobility impairment persons. Results: Of the 252 optical shops surveyed, 114 (45.2%) have resolved the problems of height difference through improving horizontal accessibility (61) or using ramps (53). 36 (14.3%) optical shops chose automatic doors for opening and closing methods of the entrance. Implications: The rate of installation of access convenience facilities for the entrance of optical shops is slightly lower than the rate of installation of ramps, surveyed by the Ministry of Health and Welfare. It is necessary to apply the Universal Design to access convenience facilities for the entrance of optical shops for not only the mobility impairment persons but all people, regardless of age or ability, to conveniently access healthcare services.

  • This paper considers a downlink cognitive radio (CR) network where one secondary user (SU) and one primary user (PU) share the same base station (BS). The spectrum of interest is divided into a set of independent, orthogonal subchannels. The communication of the PU is of high priority and the quality of service (QoS) is guaranteed by the minimum rate constraint. On the other hand, the communication of the SU is of low priority and the SU opportunistically accesses the subchannels that were previously discarded by the PU during power allocation. The BS assigns fractions ?? and 1 ?? of the total available transmit power to the PU and the SU respectively. Two power allocation schemes with opportunistic subchannel access are proposed, in which the optimal values of ??'s are also obtained. The objective of one scheme is to maximize the rate of the SU, and the objective of the other scheme is to maximize the sum rate of the SU and the PU, both under the PU minimum rate constraint and the total transmit power constraint. Extensive simulation results are obtained to verify the effectiveness of the proposed schemes.

  • The purpose of this research is to evaluate Seoullo 7017 based on Universal Design (UD) principles and guidelines. To derive UD principles applicable to the site context, we used the 2017 Seoul Universal Design Guideline and assessment index provided by the Universal Design Research Center and established 11 evaluation criteria. With respect to research methods, a literature review and on-site field survey were applied, through which we derived UD principles and evaluation criteria to identify UD problems. The 11 evaluation criteria consist of pedestrian space, facilities, access, main entrance, parking lots, trails, restrooms, convenience facilities, information facilities, rest areas, and playgrounds, and these were associated with UD principles for evaluation. As a result, the main entrance had the highest UD score, while parking lots had the lowest in terms of equity, safety, simplicity, and accessibility. Restrooms received a lower UD score because of poor conditions of security and alert systems. Rest areas were found to be uncomfortable for disabled people. With respect to the internal trails, we found the lack of braille block and irregular placement of planting pots made blind people uncomfortable when walking. In terms of UD principles, flexibility received the highest score, followed by amenity, equity, simplicity, tolerance, accessibility, and safety. Flexibility received the highest score, owing to the provision of proper information about convenience facilities and trails, while safety received the lowest, based on poor access to parking lots, inadequate paving materials and colors, and a lack of 24-hour security systems. We hope this research contributes to improving the universal design, so that people are not discriminated against in the use of the park in terms of age, sex, or physical disability. We expect the study to help facilitate empirical studies to verify UD principles and provide improved quality of UD for Seoullo 7017.

  • The study was intended to evaluate common spaces of office building in view point of universal design. The common spaces were access road, main entrance, parking lot, corridor, and restroom. Two office buildings in Centum city of Busan were evaluated by their workers, each 100 ones. The check list for evaluating them consisted of 36 universal design elements which related to five common spaces. First, there were many universal design elements which need to be improved. Second, among five common spaces, restroom has the most elements to be rated low. First of all, at least one restroom for wheelchair should be provided each floor. Third, even though both of two office buildings were recently built, there were significant difference between their users' evaluations. This implies that the concept of universal design is not applied to office buildings well. Fourth, there were significant difference among users' evaluations according to age, especially in case of design related elements. This means that users' age is an important factor to be considered.

  • The decision of the USA to found the USF(Universal Service Fund) in 1983, which was aiming to support basic telecommunication services provision at affordable price in rural and high cost areas, has triggered many countries to introduce universal service support mechanisms. Korea has been also operating a universal service support mechanism since 2000 but there are lively controversies on the change of the existing support mechanism. This paper, first, will review universal service support mechanisms in major countries including USA, EU, Chile, Peru and Japan. Second, this paper will classify types of the mechanisms and review merits and demerits of the mechanisms. Finally, this paper will derive some implications for the improvement of domestic Mechanism.
