MODEL-Based Performance Quality Assessment for IoT Applications
The number of applications incorporating Internet of Things (IoT) concepts increases extraordinarily. This increase cannot continue without high-quality assurance. There are some difficulties in testing IoT applications; the system heterogeneity, test cost and time are taken to test the system, and the precision percentage of test results.A well-known and possibly the best solution to overcoming these difficulties is to model the system for evaluation purposes, known as model-based testing (MBT). This paper aims to design a model-based testing approach to assess IoT applications performance quality attributes. The ISO 25000 quality model is used as a standard for software quality assurance applications. IoTMaaS is used as a case study to implement the methodological approach. The possible test cases were generated using the ACTS combinatorial test generation tool. The performance metrics of each test case were monitored until the optimum test case was identified, with the shortest response time and the least amount of resources used. The proposed testing method appears to be successful, according to the results.

Design an Adaptive Mobile Scaffolding System According to Students’ Cognitive Style Simplicity vs Complexity for Enhancing Digital Well-Being
Cognitive style simplicity vs complexity (CSSC)
The present study is aimed to design an adaptive mobile scaffolding System (AMSS) to provide educational scaffolding to students that is compatible with their cognitive style simplicity vs complexity (CSSC), and to measure the effectiveness of the model in enhancing students' digital well-being (DWB) in the Faculty of education, University of XXXX. Semi-experimental design of two groups was used: the first experimental group received unified mobile scaffold regardless of their cognitive styles. The second experimental group received mobile scaffold that was organized and directed to the students based on their characteristics related to their CSSC. Both experimental groups received mobile scaffold as a complementary component to the lectures delivered for the Technological Innovations in Education course in the General Diploma in Education. The study sample consisted of (71) students who met the requirements and they were randomized to two experimental groups. To examine the effectiveness of the AMSS, a DWB scale was developed. Kelly's scale of CSSC was used to identify students who fell within the scope of this style. The results were statistically analyzed using T-test to compare between the groups and to determine the significance of differences. The results showed the effectiveness of the proposed model of AMSS in developing the students’ DWB compared to the unified scaffold model.

Designing Cuckoo Based Pending Interest Table for CCN Networks
Content Centric Networking (CCN) is a modern architecture that got wide attention in the current researches as a substitutional for the current IP-based architecture. Many studies have been investigated on this novel architecture but only little of them focused on Pending Interest Table (PIT) which is very important component in every CCN router. PIT has fundamental role in packet processing in both upstream process (Interest packets) and downstream process (Data packets). PIT must be fast enough in order to not become an obstruction in the packet processing and also it must be big enough to save a lot of incoming information. In this paper, we suggest a new PIT design and implementation named CF-PIT for CCN router. Our PIT design depends on modifying and utilizing an approximate data structure called Cuckoo filter (CF). Cuckoo filter has ideal characteristics like: high insertion/query/deletion performance, acceptable storage demands and false positive probability which make it with our modification convenient for PIT implementation. The experimental results showed that our CF-PIT design has high performance in different side of views which make it very suitable to be implemented on CCN routers.

Gamification Design Elements to Enhance Adolescent Motivation in Diagnosing Depression
Depression is a critical public health problem, mainly when it affects young people (adolescents). This condition is most challenging to detect in this group because they tend to think about other people's negative assumptions. Adolescents with depressive symptoms refuse to seek professional help due to their stigma and their future if they were labeled as depressed teenagers. Depression is a severe mental issue that should be detected from an early stage so that the problem can be curbed and resolved immediately. Diagnosis should be carried out to assess mental health, followed by referral to professional help. This study aims to motivate adolescents to diagnose depression levels through gamification techniques. Fifty-three secondary students participated in a survey designed in this study to measure motivation enhancement factors. The result of this study was used to develop a depression diagnosis model. The proposed model applied a gamification design technique consisting of three main ideas: gamification elements, user types, and motivational elements. This model will serve as the foundation to develop a mobile application system that can benefit users, especially adolescents, in self-diagnosing depression.

The Use of AR Technology to Overcome Online Shopping Phobia: A Systematic Literature Review
With every year’s start being a new beginning and a source of happiness, reigniting hopes and optimism around the world, the happiness and enjoyment of the year 2020 faded away quite earlier. It was not long into the year 2020 that the notorious COVID-19 hit the world. Millions of people died of it and billions of people got affected by it either directly or indirectly. With its impact on everybody, it drastically affected the business world as well; individuals lost their jobs and companies lost their businesses. However, companies learned to respond to the pandemic by converting their businesses to the online business model and the customers also shifted to online shopping. With this compelling shift, the customers still had the phobia of online shopping and tried to abstain from it as much as possible. To respond to this, a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was developed to offer a systematic and holistic literature review of the research regarding customer confidence in online shopping particularly by the use of Augmented Reality (AR) technology. The database of this review includes a set of 54 systemically selected state-of-the-art articles from Scopus database covering empirical and theory research conducted in different countries with different resource endowments. The results show that the use of AR technology can help customers in overcoming their shopping phobia and thus, it can be a source of enhanced online business for companies. Some possible opportunities for future research are also illustrated in this paper.

Performing Communicative Language Teaching in Mandarin Mobile Learning
Students should be able to develop their communication abilities instead of just concentrating on translation methods. As a result, Communicative Teaching Language (CLT) had become the most favored approach to achieving the verbal goal as it was known as the most effective strategy to enhance learners' communicative competence. However, it was not a one-size-fits-all approach, and language instructors were advised to integrate educational technology to develop learning for students. Hence, CLT Mandarin mobile learning via personal action research was conducted to determine the extent of the approach on students' oral learning attainment, attitudes, and learners' recommendations during the learning process. The communicative task used in this study was Chatting to Mandarin Native Speakers programme. Pre- and post-oral assessments had been conducted in response to research inquiries. In verifying the reliability and validity of the study, data were triangulated through students' oral assessments, Students' Diaries, Self-Reflective Journals and Focus Group Interviews. The outcomes showed that students enjoyed the activity and improved their confidence and oral competence. Also, they suggested that there should be more language activities. The findings indicated that, when designing CLT technology-integrated projects, an instructor needed to consider students' learning preferences which make the project a success.
