The role of social networking mobile applications such as WhatsApp in enhancing second language vocabulary learning among English language learners continues to be a subject of interest for many scholars. The current study aimed at examining medical English vocabulary learning among undergraduate students using WhatsApp compared to learning vocabulary via the Blackboard platform during the Covid-19 pandemic. To this end, 108 medical students (51 males, 57 females) enrolled in a first semester English for a specific English course participated in the study. A quasi-experimental design was adopted for two groups. Fifty-three students participated in the WhatsApp group and 55 students formed the Blackboard group. A pretest-posttest design was employed to collect data. Results of t-test scores did not show a significant difference between the WhatsApp and Blackboard groups on a vocabulary test. Results of a survey that measured students' opinion of the use of WhatsApp as a platform for learning new vocabulary showed positive perceptions since participants thought that WhatsApp enhanced their learning experience.

This study investigated the perceived usability of the Blackboard learning management system (LMS) amongst students at Umm Al-Qura University. A quantitative approach was employed to explore the potential relationship between Blackboard usability and social media platform usage. Additionally, the study aimed to identify other factors influencing perceived usability. Data were collected through a three-section questionnaire distributed electronically to a sample of students (n=544). The findings, based on System Usability Scale (SUS) scores, revealed that the overall perceived usability of Blackboard resided near the midpoint of the scale, indicating an "acceptable" level. A potential negative correlation emerged between social media usage time and perceived Blackboard usability. Students who reported lower social media usage exhibited higher SUS scores. Training on Blackboard usage demonstrably exerted a positive influence on perceived usability. Gender was not identified as a statistically significant factor. An analysis of student support methods revealed that seeking help from a friend was the most prevalent approach, followed by search engines, university technical support, and social media platforms. The findings suggest that implementing strategies to improve Blackboard usability at Umm Al-Qura University could be achieved through readily accessible training materials and the exploration of alternative support channels.

This is an extended paper explaining the role of E-learning and quality development in the current situation. Amid Covid:19, E-Learning has achieved a new miles stone in imparting education and all levels of institutions have transformed their learning platform from face to face to virtual learning. In this scenario E-Learning is facing two major challenges, first to ensure the ability of computer systems or software to exchange and make use of information on virtual platform (interoperability) and secondly, developing quality learning through e-Learning. To impart learning and teaching (L&T) through E-learning, Middle East University (MEU) has adopted Learning Management Services (LMS) through Blackboard. The university has three types of L&T methods; full online, Blended and Supportive. This research studies the concept, scope and dimensions of interoperability (InT) of E-Learning in MEU then the connection and interdependence between with quality development. In this paper we have described the support and the importance of finest standards and specifications for the objectives of InT of E-Learning and quality development in MEU. The research is based principally on secondary data observed from MEU E-Learning deanship. Also sample of 20 E-Learning experts at MEU were given closed ended as well as semi closed questionnaires for evaluating the assurance of InT of E-Learning and quality development. These experts are mainly certified online facilitators and admin staff. Results provide the verification of application and presence of InT of E-Learning and assured the quality development process in MEU.

This is an extended research paper focusing on the applications of Machine Learing and Artificial Intelligence in virtual learning environment. The world is moving at a fast pace having the application of Machine Learning (ML) and Artificial Intelligence (AI) in all the major disciplines and the educational sector is also not untouched by its impact especially in an online learning environment. This paper attempts to elaborate on the benefits of ML and AI in E-Learning (EL) in general and explain how King Khalid University (KKU) EL Deanship is making the best of ML and AI in its practices. Also, researchers have focused on the future of ML and AI in any academic program. This research is descriptive in nature; results are based on qualitative analysis done through tools and techniques of EL applied in KKU as an example but the same modus operandi can be implemented by any institution in its EL platform. KKU is using Learning Management Services (LMS) for providing online learning practices and Blackboard (BB) for sharing online learning resources, therefore these tools are considered by the researchers for explaining the results of ML and AI.

기존의 학교현장에서의 단방향 주입식 교육은 학습자의 학습 흥미와 몰입감, 학습능률이 매우 떨어지는 단점을 가지고 있고 집단지성, 협력학습에 한계를 드러내고 있다. 학생들의 자발적인 학습참여를 유도하여 자기주도적인 학습을 통한 학습효과를 높일 수 있는 수단으로 근거리 통신을 활용한 교육콘텐츠 서비스 플랫폼이 요구되고 있다. 본 연구는 IoT(Internet of Things) 기반의 근거리 통신기술인 블루투스를 이용해 교사음성과 교수학습이 전자칠판(Interactive White Board)과 통신하고, NFC 기술을 이용해 학생들의 개인 강의노트 콘텐츠를 재생성하여 빅데이터화 되고 학생 간 공유가 가능해짐으로써 질 좋은 교육 콘텐츠를 생성하는 스마트 스쿨에 걸맞는 교육콘텐츠 제작시스템 기술을 연구하였다.

The paper describes a formalisation of a Design for Safety methodology in an integrated envi-ronment, outlines early developments of a software tool, and presents the results of an appli-cation of the methodology to a case study. The approach adopted attempts link safety per-formance prediction through the utilisation of appropriate technical tools, safety assessment deriving from risk-based methodologies and disparate design activities and issues. Black-board systems have been utilised as the platform in the development of the integrated design environment, allowing safety assessment to become an integral part of the design process. Finally, the case study addresses the application of the developed methodology to three dif-ferent arrangements of a conventional passenger Ro-Ro vessel, with the aim to demonstrate the validity of the process and methodology adopted. The findings are presented and dis-cussed, and recommendations given for the way forward.

상황인식(context-aware)은 인간-컴퓨터 상호작용의 단점을 극복하기 위한 방범으로써 많은 주목을 받고 있다. 이 논문에서는 SoC(System-on-a-Chip)로 구현될 수 있는 상황인식 시스템 구조를 제안한다. 제안한 구조는 센서 추상화, 컨텍스트 변경에 대한 통지 메커니즘, 모듈식 개발, if-then 규칙을 이용한 쉬운 서비스 구성과 유연한 상황인식 서비스 구현을 지원한다. 이 구조는 통신 모듈, 처리 모듈, 블랙보드를 포함하는 SoC 마이크로프로세서 부분과 규칙 기반 시스템 모듈을 구현한 하드웨어로 구성된다. 규칙 기반 시스템 하드웨어는 모든 규칙의 조건부에 대해 매칭 연산을 병렬로 수행하고, 규칙의 결론부는 마이크로프로세서에 내장된 행위 모듈을 호출함으로써 작업을 수행한다. 제안한 구조의 SoC 시스템의 규칙의 매칭부분은 SystemC SoC 개발 환경에서 설계하여 구조의 타당성을 확인하였고, 마이크로프로세서에 내장될 행위모듈에 대해서는 소프트웨어적으로 타당성을 확인하였다. 제안한 SoC 기반의 상황인식 시스템 구조는 주거 환경에서 컨텍스트를 인식하여 노인을 보조하는 지능형 이동 로봇 등에 적용될 수 있을 것으로 기대된다.
