Since the beginning of the 21st century, the power source for the growth of our country is shifting from the 'knowledge and information'-centered business to the culture-based business attaching importance to 'creativity'. In the era of creative culture-based economy, the core resources on which the national competitive power depends can be thought to be 'cultural contents'. The current ubiquitous project, which is being promoted in our country, is characteristically placing much emphasis on building-up of the RFID-centered infrastructure so that it is poorly acknowledged by common people to whom its service is actually provided. In this study, the approach to promotion of the cultural service, to which an easy access is available as a result of combining the ubiquitous-based technology with 'cultural contents', is discussed in the 4 aspects.

DGPS is a technology that can improve the positioning precision of the existing GPS based on the correction information regarding reference station. Although the country is currently building infrastructure for DGPS correction information to be transmitted, it is being used only in limited areas for which DGPS expensive equipment is required. By enabling the development of the DGPS device using the smart phone, this limitation can be overcome, DGPS can be applied for various location-based services, and the implementation of the new model of location-based services may be enabled. In this paper, we introduce the development of a DGPS device for which high-precision positioning is possible using DGPS correction information received via the DMB network or mobile network in the smart phone environment.

Cameroon is a lower middle-income country with a population of 25.87 million inhabitants distributed over a surface area of 475,442 ㎢. Cameroon has very rich potentials in renewable energy resources such as solar energy, wind energy, small hydropower, geothermal energy and biomass. However, renewable energy constitutes less than 0.1% of energy mix of the country. The energy generation mix of Cameroon is dominated by large hydropower and thermal power. Cameroon ratified the Paris Agreement in July 2016 with an ambitious 20% greenhouse gas (GHG) emission reduction. This study attempts to investigate some renewable energy deployment policy-instruments that could enable the country enhance renewable energy deployment, gain energy independence, fulfill Nationally Determined Contribution (NDC) and achieve Sustainable Development Goals. It begins with an analysis of the status of energy sector in Cameroon. It further highlights the importance of renewable energy in mitigating climate change by decarbonizing the energy mix of the country to fulfill NDC and SDGs. Moreover, this study proposes some renewable energy deployment policy-solutions to the government. Solar energy is the most feasible renewable energy source in Cameroon. Feed-in Tariffs (FiT), is the best renewable energy support policy for Cameroon. Finally, this study concludes with some recommendations such as the necessity of building an Energy Storage System as well a renewable energy information and statistics infrastructure.

With the advancement of internet technology, traditional university libraries are going through metamorphosis into digital libraries. Digital libraries substitute digital files for printed materials, metadata for catalogues, world wide users on the network for localized patrons, while offering limitless possibilities for easy downloading of information. The aim of the study is to present a model for our digital library based on the knowledge auquired from the analysis of the state of the art technology employed in building and managing digital libraries and the management of large quantity of SGML electronic documents. This paper is our belief that the national information infrastructure for university digital libraries are mandatory for an open information society.

Because of the intrinsic lack of internal-system observability and controllability in highly integrated multicore processors, very restricted access is allowed for the debugging of erroneous chip behavior. Therefore, the building of an efficient debug function is an important consideration in the design of multicore processors. In this paper, we propose a flexible on-chip debug architecture that embeds a special logic supporting the debug functionality in the multicore processor. It is designed to support run-stop-type debug functions that can halt and control the execution of the multicore processor at breakpoint events and inspect the possible causes of any errors. The debug architecture consists of the following three functional components: the core debug support block, the multicore debug support block, and the debug interface and control block. By embedding this debug infrastructure, the embedded processor cores within the multicore processor can be debugged simultaneously as well as independently. The debug control is performed by employing a JTAG-based scanning operation. We apply this on-chip debug architecture to build a debugger for a prototype multicore processor and demonstrate the validity and scalability of our approach.

A physical protection system (PPS) is used for the protection of critical facilities. This paper proposes a structure analytic hierarchy approach (SAHA) for the hierarchical evaluation of the PPS effectiveness in critical infrastructure. SAHA is based on the traditional analysis methods "estimate of adversary sequence interruption, EASI". A community algorithm is used in the building of the SAHA model. SAHA is applied to cluster the associated protection elements for the topological design of complicated PPS with graphical vertexes equivalent to protection elements.

This paper provides an overview of the experiences of the people's housing process (PHP) in South Africa. The discussion is done against the backdrop of the different outcomes of the government public housing provision initiative, commonly known as the Reconstruction and Development Programme (RDP) that directly produced more than three million subsidized housing to formerly segregated and disadvantaged populations. Notwithstanding the huge success in providing the much needed accommodation to such previously marginalized communities, the over-reliance on direct provision has the PHP ostensibly less impactful in housing delivery. Against the backdrop of the soaring housing backlogs, concerns with housing quality and the financial difficulties as well as the shrinking fiscal space; the article recommends improved support of the PHP. This can be achieved by the adoption of innovations that make land and minimal infrastructure and services available to the urban poor and to support their initiatives of self-building.

Vehicular communication networking is one of the most important building blocks of Intelligent Transportation System(ITS). The vehicular communication network is a wireless communication system enabling vehicles to communicate with each other as well as with roadside base stations. Especially, Wi-Fi based vehicle-to-infrastructure(V2I) communication is an emerging solution to improve the safety, traffic efficiency, and comfort of passengers. In this paper, we proposed a new communication hub platform for vehicles, and explained vehicle communication technology in short. Through car simulation results, we show thar our proposed system reduces signaling interference.
