The increasing growth of internet and e-commerce had bartered the customer’s purchasing feature and service providers’ service policies. Moreover, there is no other criterion for quality of service (QoS) on the online network. Here the paper’s objective is to employ the importance of QoS to measure the utility quality of monetary enterprise on internet (e.g., Facebook (FB)). In this paper, the Weighted Sum method and Weighted Product method (WSM and WPM) are implemented using FB for their promotion and advertisement and then utilized the intuitionistic fuzzy value for the measuring of the QoS. The proposed methods are generally based on IF-aggregation operators and criterion weights. To calculate criterion weight, new intuitionistic fuzzy divergence is developed. Additionally, the IF-TOPSIS (technique for order preference by similarity to ideal) algorithm is also applied to check the validity of the result. This research examine not only the dimensions of QoS that users on FB liked and major brands are ‘preferred by’ by them, and which results as the most highly ranked features.

Investigating the redundancy effect in the learning of C++ computer programming using screencasting
Статья научная
The purpose of this study is to investigate whether does the redundancy principle occurs or not in the learning of C++ computer programming using screencasting. This principle was discovered by Mayer’s Cognitive Theory of Multimedia Learning (CTML) and stated that students learn better from graphics, and narrations than from graphics, narrations and on-screen text. There were mix outcomes pertaining to this principle, and the result might be due to the various topics learn by the students. Therefore, the subject introduction to C++ computer programming was chosen in this study to determine whether the redundancy principle occurs or not in the learning of C++ computer programming using screencasting. A true experimental pre-test and post-test research design was conducted, and sample were 65 first-year undergraduate students (aged 19-22). Samples were chosen based on the criteria that they have never attended any formal computer programming course prior to the study and were randomly assigned to two types of learning modes. The first group received the screencasting and narration (SN) mode whereas the second group received the screencasting, text, and narration (STN) mode. Results showed that the SN mode students outperformed the STN mode students in the post-test.

Investigation of Participation and Quality of Online Interaction
Статья научная
Advances in computer mediated communication technologies have sparked and continue to facilitate the proliferation of online courses, degree programs, and educational institutions. Leading the way with these advances has been the use of asynchronous discussion forums. However merely setting up a discussion forum does not always ensure quality participation and interaction. The way the course is managed has an impact on the participation as well. This paper compares the difference in course management over four study periods and discusses the resulting consequences on the participation and achievement of the students. This paper also investigates the quality of interaction as perceived by fully online students. The main benefits of this research are that it provides a guideline regarding what course management factors can make the difference in online participation in fully online courses, and how the quality of interaction can be designed.

To determine the need for simulated training of e-commerce activities prior to working in the real environment, we studied the views of undergraduates and college teachers from several aspects. Two hundred university students while also 200 college teachers were asked what the real problem was when they learned or taught in the e-commerce courses. Next, they were surveyed to inquire what knowledge they really need when students go to work positions and what type of job do they expect to have. Finally, they were asked whether using a simulated training platform would be beneficial. Through analysis, the aspects which are contained above we know that simulation should be incorporated into the education of e-commerce to students as a tool to practice their hands-on abilities prior to working. And from the survey we also obtain some useful information and references that may help us to design our electronic commerce training platform.

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.

Large Language Models (LLMs) have received significant attention due to their potential to transform the field of education and assessment through the provision of automated responses to a diverse range of inquiries. The objective of this research is to examine the efficacy of three LLMs - ChatGPT, BingChat, and Bard - in relation to their performance on the Vietnamese High School Biology Examination dataset. This dataset consists of a wide range of biology questions that vary in difficulty and context. By conducting a thorough analysis, we are able to reveal the merits and drawbacks of each LLM, thereby providing valuable insights for their successful incorporation into educational platforms. This study examines the proficiency of LLMs in various levels of questioning, namely Knowledge, Comprehension, Application, and High Application. The findings of the study reveal complex and subtle patterns in performance. The versatility of ChatGPT is evident as it showcases potential across multiple levels. Nevertheless, it encounters difficulties in maintaining consistency and effectively addressing complex application queries. BingChat and Bard demonstrate strong performance in tasks related to factual recall, comprehension, and interpretation, indicating their effectiveness in facilitating fundamental learning. Additional investigation encompasses educational environments. The analysis indicates that the utilization of BingChat and Bard has the potential to augment factual and comprehension learning experiences. However, it is crucial to acknowledge the indispensable significance of human expertise in tackling complex application inquiries. The research conducted emphasizes the importance of adopting a well-rounded approach to the integration of LLMs, taking into account their capabilities while also recognizing their limitations. The refinement of LLM capabilities and the resolution of challenges in addressing advanced application scenarios can be achieved through collaboration among educators, developers, and AI researchers.

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.

Learner Modeling in Adaptive Educational Systems: A Comparative Study
Статья научная
It's worth noting that the present paper lies within the range of modeling the learner in adaptive educational system as a conceptual modeling of the learner. Thought they are several methods that deal with the learner model; like stereotypes methods or learner profile…, but they are likely unable to handle the uncertainty embedded in the dynamic modeling of the learner. The present paper aims at studding different models and approaches to model the learner in an adaptive educational systems, and coming up with the most appropriate method based on the dynamic aspect of this model. The aim of this study is the argue that the learner model cannot be completely modeled based on one single method through the entire development process, but it needs a combination between several methods that will help for a complete modeling.
