Assistive technologies are necessary for ensuring independent living and equal participation in an information-based society for people living with disabilities (PLWD). This study investigated the assistive technology preference of students with visual disabilities, and the approach academic libraries should adopt in procuring assistive technologies. The study adopted a quantitative research method, with a survey as the research design. The study was conducted among visually disabled students in four public universities in Nigeria. Using the total enumeration method, an online questionnaire was used to obtain information from 151 students who voluntarily agreed to partake in the survey. The study found that access to electronic resources, scanning/conversion of print resources to electronic formats and access to information on the Web were among the technology-based services provided to visually disabled students. COBRA, ZoomText, Supernova and Dragon Naturally Speaking are the most preferred assistive technologies (software). At the same time, handheld scanners ($\bar{x}=4.40$) and braille keyboards ($\bar{x}=4.60$) are the most preferred assistive technologies in the hardware category by visually challenged students. The study further revealed that the library management should consult with students living with a visual disability before procuring assistive technology. Findings from this study thus provide further evidence of the need for librarians to fulfil their moral and legal obligation in advocating the provision of assistive technologies. Library administrators and university stakeholders should expedite actions on meeting the assistive technology needs of people living with visual disabilities. These actions should transcend mere policy formulation on the provision of assistive technologies to restructuring their services and spaces to accommodate assistive technologies as information service delivery tools for people with visual disabilities.

Nigeria Copyright Commission is saddled with the responsibility of ensuring adherence to the copyright law in Nigeria. However, it has been observed in the last decade that copyright right issue is still rampant in Nigeria. Therefore, this study analyzed cases that the Commission in involved in between years 2008 to 2018. The study adopted citation analysis. The study collected data from three selected law reports, which include Intellectual Property Law Reports, Nigerian Weekly Law Reports and Nigeria Law Intellectual Property Watch. It was found that Nigerian Law Intellectual Property Watch has the highest number of reports of cases involving Nigerian Copyright Commission while none was reported by Nigerian Weekly Law Reports. It was also found that most of the cases handled by the Commission were on copyright infringement. The study concludes that Nigerian Copyright Commission has been paying credible attention to issue that surrounds software infringement but there has been little attention paid to book piracy. Moreover, it was established that the poor attention given to book piracy may entrench the publication of pirated copy and would subsequently lead to poor library service provision at the long run.

Recently, due to decrease hardware prices and the development of technology, analog signage has been changing to digital signage for providing content such as advertisements, videos. Furthermore, in order to provide advertisements and contents to users more effectively, technical researches are being conducted in various industries. In addition, including digital signage that uses displays, it can be seen that it provides advertisements and contents using diverse devices such as LED signage, smart pads, and smart phones. However, most digital signage is installed in one place to provide contents and provides interactivity through simple events such as manual content provision or touch. So, in this paper, we suggest a new object detection algorithm based on an adjacent frames based image correction algorithm for interactive building signage.

동화상 압축 기술과 네트워크의 발달로 빠르게 보급된 디지털 콘텐츠는 불법복제와 인터넷을 통한 유포로 인해 지적 재산권 보호의 필요성이 대두되었다. 이에 다양한 표준화 단체들과 콘텐츠 제공업체들이 디지털 콘텐츠 보호를 위한 솔루션을 개발하였고 이 과정에서 서로 다른 독자적인 솔루션 개발로 인하여 이기종 디지털 콘텐츠 보호 시스템간의 상호운용성 결여라는 문제에 봉착하게 되었다. 이 문제를 해결하기 위해 MPEC(Moving Picture Experts Group) 단체에서 이기종간의 상호운용 가능한 IPMP(Intellectual property Management and Protection) 기술에 대한 표준화를 진행하였으나 만족할 정도의 기능을 제시하지 못하면서 이에 대한 대안으로 DMP(Digital Media Rroject) 표준이 제시되었다. 이에 본 논문에서는 MPEG의 IPMP 표준을 분석하고 이를 보완하기 위해 DMP의 툴팩(ToolPack)을 사용하여 이기종간의 상호운용성 확보가 가능한 디지털 콘텐츠를 보호 시스템을 설계 및 구현하였다.

The purpose of this study was to evaluate comparatively the content of the Expanded National Immunization Program according to the provision method between 2005 and 2006 in Korea. We assessed the impact of the mutually exclusive vaccination policy using the result reports of the 2005 and 2006 Demonstration Project and the related references by the content analysis. The public health centers paid vaccination fees to the private clinic and hospital in the 2005 Demonstration Project in Daegu metropolitan city and Gunpo city. But, the public health centers directly supplied free vaccination services to the children in the 2006 Demonstration Project in Gangneung city, Yangsan city, and Yeongi-gun. The total budgets of 2005 and 2006 Demonstration Project were 6.57 billion won and 0.65 billion won, respectively. The computerized registration rates and timeliness rates of administration of each vaccination had improved all in the 5 Demonstration Project regions. However, the computerized registration rates of most vaccination in Gunpo city were higher than those in the 2006 Demonstration Project regions except hepatitis B. Especially, the computerized registration rate of BCG was 48.3%, but the BCG coverage rate by the follow-up telephone survey was 99.8% in Daegu metropolitan city. The community parents in all the regions were satisfied because of expanding financial and geographical access to immunization coverage. In conclusions, from the aspect of the main outcomes, the implementation of two different financial immunization aids appears to be widely accepted among these parents and to have had an impact on vaccination coverage. In the future, the government must try to enact that the national immunization policy including under-immunised or incompletely immunised groups would be achieved by the affordable method of the public-private dynamics.

Broadcasting services sector has been facing strong public pressure to shift gears from regulation to deregulation since mid-1990s, where a triggering role was played particularly by rapid development of IT technology and content digitization. Major agenda was how to reduce regulatory divides between more liberal telecommunication sector and less liberal broadcasting. After all, common solution package worldwide was for the latter to switch over from network-dependent(vertical) to network-independent(horizontal) regulation, and to facilitate more open and competitive transmission with content market kept protected. This is no other than decoupling content provision from broadcasting and promoting market access towards the latter. Policy experiences of US and UK show that there exists a complementary relationship between quantitative and qualitative restrictions in implementing such deregulation. While mitigating quantitative ownership regulations in broadcasting, they also sought to systematize, so-called, PIT(public interest test) as a qualitative safety device to cope with the risk of losing fundamental public values accordingly in broadcasting. Recent domestic progress in broadcasting legislation in 2009, however, seems to overlook the growing importance of PIT in the process of deregulation. Bearing this motivation in mind and taking account of the relevant WTO disciplines, this paper is to address policy issues and suggestions for PIT in Korea's broadcasting services sector.

A future nuclear energy system is being developed at Korea Atomic Energy Research Institute (KAERI), the system involves a Sodium Fast Reactor (SFR) linked with the pyro-process. The pyro-process produces a source material to fabricate a SFR fuel rod. Therefore, an isotopic fissile content assay is very important for fuel rod safety and SFR economics. A new technology for an analysis of isotopic fissile content has been proposed using a lead slowing down spectrometer (LSDS). The new technology has several features for a fissile analysis from spent fuel: direct isotopic fissile assay, no background interference, and no requirement from burnup history information. Several calculations were done on the designed spectrometer geometry: detection sensitivity, neutron energy spectrum analysis, neutron fission characteristics, self shielding analysis, and neutron production mechanism. The spectrum was well organized even at low neutron energy and the threshold fission chamber was a proper choice to get prompt fast fission neutrons. The characteristic fission signature was obtained in slowing down neutron energy from each fissile isotope. Another application of LSDS is for an optimum design of the spent fuel storage, maximization of the burnup credit and provision of the burnup code correction factor. Additionally, an isotopic fissile content assay will contribute to an increase in transparency and credibility for the utilization of spent fuel nuclear material, as internationally demanded.

The models used for ionosphere error correction in positioning using Global Navigation Satellite System (GNSS) are representatively Klobuchar model and NeQuick model. Although these models can correct the ionosphere error in real time, the disadvantage is that the accuracy is only 50-60%. In this study, a method for polynomial modeling of Global Ionosphere Map (GIM) which provides Vertical Total Electron Content (VTEC) in grid type was studied. In consideration of Ionosphere Pierce Points (IPP) of satellites with a receivable elevation angle of 15 degrees or higher on the Korean Peninsula, the target area for model generation and provision was selected, and the VTEC at 88 GIM grid points was modeled as a polynomial. The developed VTEC polynomial model shows a data reduction rate of 72.7% compared to GIM regardless of the number of visible satellites, and a data reduction rate of more than 90% compared to the Slant Total Electron Content (STEC) polynomial model when there are more than 10 visible satellites. This VTEC polynomial model has a maximum absolute error of 2.4 Total Electron Content Unit (TECU) and a maximum relative error of 9.9% with the actual GIM. Therefore, it is expected that the amount of data can be drastically reduced by providing the predicted GIM or real-time grid type VTEC model as the parameters of the polynomial model.
