Issues of Technical Support for e-Learning Systems in Higher Education Institutions
Статья научная
Information and communication technologies (ICTs) have provided several tools to facilitate higher education. However, their effective use demands technical expertise to achieve the required academic goals. The university constituents (teachers, students and administrators) are given eTraining but this is not enough. Every eLearning system establishes a basic ‘infrastructure’ of computers, networks, communications and a technical department filled with ICT professionals to consistently maintain and upgrade the infrastructure, train the users and continuously provide technical support as and when required by them. Given the non-stop nature of technical support for eLearning, HEIs are facing issues in creating robust infrastructural facilities that are both competitive with the external environment and compatible with the internal user requirements. This article is a compendium of the touchy aspects in sustained technical support for eLearning in HEIs.

Issues on E-health Adoption in Nigeria
Статья научная
E-health is the application of information technology for health care management. It includes all applications of information communication technologies to promote healthcare services support, delivery and education for improving efficiency in health care delivery to the citizens. Many factors contribute to the poor state of the medical sector of Nigeria, and in fact many developing countries, two of the most important being record keeping and accessibility. Nigeria still operates a paper based healthcare delivery system; meeting demands of citizens have been increasingly difficult due to her huge population, understaffed hospitals, apathy towards embracing ICTs and other issues. On the other hand, ICT applications have been used successfully in developed countries to address most of these problems. This paper presents an in-depth analysis of the healthcare system in Nigeria while highlighting confronting issues with a view to proposing a viable solution.

K-12 Curriculum Research: The Chicken and the Egg of Math-aided ICT Teaching
Статья научная
In this article, we examine the relationship in K-12 education between Mathematics and Information and Communication Technology (ICT). The topic is reviewed from various angles, based on both a literature study and by directly contrasting the Finnish National Curriculum (FNC) of 2014 (effective since autumn 2016) with the National Curriculums of the UK (UKNC)[3] and the US (USCC)[2]. Finland has chosen a cross-curricular approach to developing the new curriculum for teaching ICT, which involves integrating it mainly with math, but also with handicraft, and various other subjects. This is in direct contrast to the UKNC, for example, which teaches ICT as its own field, to be taught through the Computing and Design/Technology syllabi. This poses a question for this research study, namely, how well do teaching math and ICT fit together? The first step towards answering this question is to establish which ICT concepts and domains are directly supported by math and which are left uncovered. As a theoretical research paper, the rationale for the inter-connectedness of math and ICT is based on the work of many researchers. To illustrate our comparison of the two subjects, in this article we concentrate on clarifying math's and ICT's shared concepts of variable and function. The results of this study indicate that transfer between the subjects happens bi-directionally, which might suggest that teaching ICT in combination with particular branches of math, notably algebra would be of benefit to our students. In order to pursue this approach, extra modules for logic, basic linear algebra and set theory would also be required. The fundamentals of basic algebra, the function and the variable, and their significance as synthesizers in both algebra and ICT are highlighted. In addition, the use of calculators as function tutors is explored in an instructional classroom setting. The conclusion of this study is that although there are certain benefits to the currently chosen approach of teaching ICT in combination with mathematics, these are not enough to outweigh the advantages of adopting a more versatile dedicated ICT syllabus, such as that provided by the UKNC.

Knowledge Representation by Analogy for the Design of Learning and Assessment Strategies
Статья научная
The difficulty of learning a novel knowledge may not be the same for each learner. Often instructors try to find the easiest way to make a new knowledge understandable by most learners, but few of them give importance to the use of analogies which is the common practice in real life situations. This paper attempts to highlight that learning by analogy allows making the understanding of a novel and complicated knowledge easier. We first propose a model that represents the desired knowledge in an abstract way which allows us to find analogies in different domains. Based on these analogies, learning and assessment strategies can be derived in order to improve the learning outcome. Secondly, the design of a computer system that integrates the analogies, learning and assessment strategies into a digital learning environment is proposed.

Data mining or the discovery of knowledge out of databases extracts patterns, and useful and non-substantial, implicit, and unknown information from large databases. Searching for associative rules is a data mining method where relationships and dependencies Interactions between a large set of data items are shown. In large organizations, most data are created at the passage of time. Relational tables in a variety of business or scientific domains have rich information, with high quantative and nominal data types. Therefore, in order to gather information, measure performance and increase business efficiency, it is necessary to isolate relational database and store data in a data warehouse. Using the multidimensional data mining that integrates online analytical processing with data mining, knowledge can be found in multidimensional databases. In this article, to avoid inappropriate rules in exploring associative rules, the online analytical processing technique is combined with the Apriori algorithm and explores associative rules on multi-dimensional and multilevel data using the data cubic and Apriori algorithm. In addition, the criteria of accuracy, tool performance, and runtime are defined for comparing techniques for exploring associative rules. The metrics mentioned in the scope of this paper have been compared, and data from the Central Insurance Agency have been analyzed using data cubes and the Apriori algorithm, and useful association rules have been generated. Results of the research displays improvement of the response time compared to the other methods.

LINE messenger as a transport layer to distribute messages to partner instant messaging
Статья научная
The rapid development of technology generated a lot of instant messaging applications, as an example is LINE Messenger, Telegram, WhatsApp, Facebook Messenger, BlackBerry Messenger, etc. Many instant messaging applications cause some problems, one of which is the possibility of owning more than one instant messaging applications to meet messaging needs. This is very ineffective because messages will be received from various instant messaging applications and have to open all instant messaging applications one by one to reply to those messages. Application Programming Interface technology of instant messaging can be used to build a transport layer system that allows message exchange with several instant messaging applications using only one instant messaging application. The system built in this research requires a master instant messaging to be able to distribute messages to partner instant messaging, which in this case uses LINE Messenger as the master instant messaging to distribute messages to several partner instant messaging, which is Telegram and Extensible Messaging Presence Protocol.

Lean agile integration for the development of large size projects
Статья научная
Scrum is a well-known agile model due to its strong management practices. It can be mingled with many software development models such as extreme programming (XP), Agile Unified Process, and Feature Driven Development (FDD). Lean is a very popular known process in the automobile industry due to its effective practices such as Kanban bard and smooth workflow. Lean development is gaining popularity in the software industry from the last few years. Lean development is rational, convenient, responsive, and team-based and it adds value to the enterprise. Scrum is useable and practical for small and medium projects but it does not render positive support for the large size projects. In order to adopt Scrum for large size projects, there is a need to integrate Lean and Scrum. It is required to inherit some properties of the Lean into Scrum, without compromising the speed, quality, efficiency, and standards, to accomplish large size projects successfully such as enterprise resource planning (ERP) systems. It is anticipated that the proposed Lean Scrum integration will make it suitable to develop large size projects. The same is accomplished by purposing an integrated LScrum model in this research. The proposed model is validated using a survey to conclude the results. The results of the survey support the proposed integration of Lean and Scrum for the development of large size projects.

Leveraging the Saudi linked open government data: a framework and potential benefits
Статья научная
Open data initiatives are a crucial aspect of effective e-governance strategy. They embody aspirations towards sociopolitical values of transparency, trust, confidence, and accountability, pertaining to the relationship between a government and its citizens. The importance of such initiatives is especially important for an emerging economy such as Saudi Arabia which is undergoing rapid social changes directed by a contemporary national vision. The effectiveness of open data initiatives depends strongly on (a) the quality of the data available, (b) the soundness of the methodologies and suitability of platforms used to prepare and present the data, and (c) the ability of the data to facilitate the kinds of insights and social-action that are sought from that data to ensure successful e-governance. This paper investigates the feasibility of current Saudi government open data initiatives in this regard. It assesses existing approaches to improve the effectiveness of open government data through transforming it into linked-open data (using the Resource Description Framework [RDF]) by connecting disparate sources of structured data therein. It proposes to improve existing approaches by suggesting a framework for automating the linking sub-process of existing approaches and organizing the data to be queried through SPARQL. Moreover, it evaluates the potential benefit of this proposal by discussing the kinds of policy insights this could generate which would be difficult without it.

Статья научная
This paper presents an effective compression technique for lossy compression of color images. After reducing the correlation among R, G and B planes using YCoCg-R transform, the Integer Wavelet Transform (IWT) is applied on each of the transformed planes independently up to a desired level. IWT decomposes the input image into an approximation and several detail subbands. Approximation subband is compressed losslessly using prediction errors and Huffman coding, while each of the detail subbands are compressed independently using an effective quantization and Huffman coding. To show the effectiveness of proposed scheme, it is compared with several existing schemes and a state of art for image compression JPEG2000 and it is observed that the proposed scheme outperforms over the existing techniques and JPEG2000 with less degradation in the quality of reconstructed images while achieving high compression performance.
