When an individual selects a photo, PhotoRoom automagically removes or separates the background from other parts of the photo through the use of artificial intelligence. This will allow an individual to select their desired background and edit it as they wish. The methodology used was an observation, where various reviews and parts of the app were observed. The review section's findings showed that many people actually like the app, and some even rated it five stars. The conclusion was that PhotoRoom is one of the best photo editing apps due to its speed and accuracy in removing backgrounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=removing%20background" title="removing background">removing background</a>, <a href="https://publications.waset.org/abstracts/search?q=app" title=" app"> app</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/137271/photoroom-app" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137271.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">199</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Requirements Gathering for Improved Software Usability and the Potential for Usage-Centred Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kholod%20J.%20Alotaibi">Kholod J.

Although methods exist to incorporate elements of usability engineering, there is a need for more balanced usability focused methods that can enhance the experience of software usability for users. In this regard, the potential for Usage-Centered Design is explored with respect to requirements gathering and is shown to lead to high software usability besides other benefits. It achieves this through its focus on usage, defining essential use cases, by conducting task modeling, encouraging user collaboration, refining requirements, and so on.

The study implements a mixed methods approach. First, a questionnaire was administered to 64 students from two schools in Almadinah, a Saudi city. Then, in structured interviews, two English teachers provided their opinions on the advantages and disadvantages of integrating Plickers into their classrooms. The findings reveal that both teachers and students believe that using Plickers positively impacts students’ learning. Moreover, the findings encourage teachers to integrate technology-based formative assessments in EFL classrooms. However, there are some drawbacks to using Plickers, such as technological issues. Finally, English teachers are recommended to engage all their students in a daily formative assessment by implementing Plickers in their classes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plickers" title="plickers">plickers</a>, <a href="https://publications.waset.org/abstracts/search?q=formative%20assessment" title=" formative assessment"> formative assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a>, <a href="https://publications.waset.org/abstracts/search?q=EFL%20classroom" title=" EFL classroom"> EFL classroom</a> </p> <a href="https://publications.waset.org/abstracts/144124/the-effectiveness-of-using-plickers-as-a-formative-assessment-tool-in-efl-classrooms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144124.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Experimental Investigation on Correlation Between Permeability Variation and Sabkha Soil Salts Dissolution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fahad%20A.%20Alotaibi">Fahad A.

These views were obtained through two group interviews with the students and parents separately. Several causes were brought up during the two interviews. These causes included difficulty of the English language, weak teacher performance, the need to pass exams with high marks, lack of parents’ follow-up of student school performance, social pressure, variability in student comprehension levels at school, weak English foundation in previous school years, repeated student absence from school, large classes, as well as English teachers’ heavy teaching loads. The study started with a description of the EFL educational system in Saudi Arabia and concluded with recommendations for the improvement of the school learning environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=english" title="english">english</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20difficulty" title=" learning difficulty"> learning difficulty</a>, <a href="https://publications.waset.org/abstracts/search?q=private%20tutoring" title=" private tutoring"> private tutoring</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi" title=" Saudi"> Saudi</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20practices" title=" teaching practices"> teaching practices</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20environment" title=" learning environment"> learning environment</a> </p> <a href="https://publications.waset.org/abstracts/28899/perspectives-of-saudi-students-on-reasons-for-seeking-private-tutors-in-english" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28899.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">456</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Human Motion Capture: New Innovations in the Field of Computer Vision</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Najm%20Alotaibi">Najm Alotaibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human motion capture has become one of the major area of interest in the field of computer vision.

Hence, it is required to replace these vehicles with more environment-friendly vehicles. Electric Vehicles (EVs) are promising technologies which offer both human comfort “noise, pollution” as well as reduced (or no) emissions of GHGs. In this paper, different types of EVs are reviewed and their advantages and disadvantages are identified. It is found that in terms of fuel economy, Plug-in Hybrid EVs (PHEVs) have the best fuel economy, followed by Hybrid EVs (HEVs) and ICE vehicles. Since Battery EVs (BEVs) do not use any fuel, their fuel economy is estimated as price per kilometer. Similarly, in terms of GHG emissions, BEVs are the most environmentally friendly since they do not result in any emissions while HEVs and PHEVs produce less emissions compared to the conventional ICE based vehicles. Fuel Cell EVs (FCEVs) are also zero-emission vehicles, but they have large costs associated with them. Finally, if the electricity is provided by using the renewable energy technologies through grid connection, then BEVs could be considered as zero emission vehicles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicles" title="electric vehicles">electric vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20emission%20car" title=" zero emission car"> zero emission car</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20economy" title=" fuel economy"> fuel economy</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20footprint" title=" CO₂ footprint"> CO₂ footprint</a> </p> <a href="https://publications.waset.org/abstracts/124768/a-review-on-the-potential-of-electric-vehicles-in-reducing-world-co2-footprints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124768.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Perceptions of Corporate Governance and Business Ethics Practices in Kuwaiti Islamic and Conventional Banks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Alotaibi">Khaled Alotaibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah%20Alhamadi"> Salah Alhamadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibraheem%20Almubarak"> Ibraheem Almubarak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study attempts to explore both corporate governance (GC) and business ethics (BE) practices in Kuwaiti banks and the relationship between CG and BE, using an accountability framework. By examining the perceptions of key stakeholder groups, this study investigates the practices of BE and CG in Islamic banks (IBs) compared to conventional banks (CBs). We contribute to the scarce studies concerned with relations between CG and BE. We have employed a questionnaire survey method for a random sample of crucial relevant stakeholder groups. The empirical analysis of the participants’ perceptions highlights the importance of applying CG regulations and BE for Kuwaiti banks and the clear link between the two concepts. We find that the main concern is not the absence of CG and BE codes, but the lack of consistent enforcement of the regulations. Such a system needs to be strictly and effectively implemented in Kuwaiti banks to protect all stakeholders’ wealth, not only that of stockholders. There are significant patterns in the CG and BE expectations among different stakeholder groups. Most interestingly, banks’ client groups illustrate high expectations concerning CG and BE practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title="corporate governance">corporate governance</a>, <a href="https://publications.waset.org/abstracts/search?q=GC" title=" GC"> GC</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20ethics" title=" business ethics"> business ethics</a>, <a href="https://publications.waset.org/abstracts/search?q=BE" title=" BE"> BE</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20banks" title=" Islamic banks"> Islamic banks</a>, <a href="https://publications.waset.org/abstracts/search?q=IBs" title=" IBs"> IBs</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20banks" title=" conventional banks"> conventional banks</a>, <a href="https://publications.waset.org/abstracts/search?q=CBs" title=" CBs"> CBs</a>, <a href="https://publications.waset.org/abstracts/search?q=accountability" title=" accountability"> accountability</a> </p> <a href="https://publications.waset.org/abstracts/116002/perceptions-of-corporate-governance-and-business-ethics-practices-in-kuwaiti-islamic-and-conventional-banks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116002.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Challenges in Promoting Software Usability and Applying Principles of Usage-Centred Design in Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kholod%20J.%20Alotaibi">Kholod J.

The study confirms the need to raise awareness of usability and its importance, and for Usage-Centred Design to be applied in its entirety, also need to encourage greater consultation with potential end-users of software and collaborative practices. The demonstration of Usage-Centred Design confirmed its ability to capture usability requirements more completely and precisely than would otherwise be the case, and hence its usefulness for developers concerned with improving software usability.

In theory, the government of the Kingdom of Saudi Arabia (Saudi Arabia) has committed itself to school counseling programs in educational institutions throughout the country. Student counselors face a number of burdens and obstacles that impact student counseling programs. It is also widely known that Saudi Arabia has extremely high prevalence rates for overweight and obesity, anxiety and depression, and diabetes in children. It has also been demonstrated that teachers and staff are inadequately prepared when dealing with health issues relating to diabetes in schools in Saudi Arabia. This study will clearly demonstrate how student counselors in Saudi Arabia could become 'New Educators' in Saudi schools in relation to these health issues. This would allow them to leverage their position as student counselor to improve the management of these health issues in Saudi schools, to improve the quality of care provided to school children, and to overcome burdens and obstacles that are currently negatively affecting student counseling in Saudi schools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anxiety%20and%20depression" title="anxiety and depression">anxiety and depression</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes" title=" diabetes"> diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=overweight%20and%20obesity" title=" overweight and obesity"> overweight and obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=policy%20recommendations" title=" policy recommendations"> policy recommendations</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20counseling" title=" student counseling"> student counseling</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Kingdom%20of%20Saudi%20Arabia" title=" The Kingdom of Saudi Arabia"> The Kingdom of Saudi Arabia</a> </p> <a href="https://publications.waset.org/abstracts/51729/the-new-educators-the-reasons-for-saudi-arabia-to-invest-more-in-student-counseling-programs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51729.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">357</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Crystal Nucleation in 3D Printed Polymer Scaffolds in Tissue Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amani%20Alotaibi">Amani Alotaibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 3D printing has emerged as a pivotal technique for scaffold development, particularly in the field of bone tissue regeneration, due to its ability to customize scaffolds to fit complex geometries of bone defects. Among the various methods available, fused deposition modeling (FDM) is particularly promising as it avoids the use of solvents or toxic chemicals during fabrication. This study investigates the effects of three key parameters, extrusion temperature, screw rotational speed, and deposition speed, on the crystallization and mechanical properties of polycaprolactone (PCL) scaffolds. Three extrusion temperatures (70°C, 80°C, and 90°C), three screw speeds (10 RPM, 15 RPM, and 20 RPM), and three deposition speeds (8 mm/s, 10 mm/s, and 12 mm/s) were evaluated. The scaffolds were characterized using X-ray diffraction (XRD), differential scanning calorimetry (DSC), and tensile testing to assess changes in crystallinity and mechanical properties. Additionally, the scaffolds were analyzed for crystal size and biocompatibility. The results demonstrated that increasing the extrusion temperature to 80°C, combined with a screw speed of 15 RPM and a deposition speed of 10 mm/s, significantly improved the crystallinity, compressive modulus, and thermal resistance of the PCL scaffolds. These findings suggest that by fine-tuning basic 3D printing parameters, it is possible to modulate the structural and mechanical properties of the scaffold, thereby enhancing its suitability for bone tissue regeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title="3D printing">3D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer" title=" polymer"> polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=scaffolds" title=" scaffolds"> scaffolds</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20engineering" title=" tissue engineering"> tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallization" title=" crystallization"> crystallization</a> </p> <a href="https://publications.waset.org/abstracts/194998/crystal-nucleation-in-3d-printed-polymer-scaffolds-in-tissue-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194998.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Active Learning Role on Strategic I-Map Thinking in Developing Reasoning Thinking and the Intrinsic-Motivation Orientation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Alotaibi">Khaled Alotaibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with developing reasoning thinking and the intrinsic-extrinsic motivation for learning, and enhancing the academic achievement of a sample of students at Teachers' College in King Saud University.

However, to date, few studies have investigated SA’s MVT problem. Those that have are primarily focused on the characteristics of car thieves, and most have overlooked any spatial-temporal distribution of MVT incidents and the characteristics of victims. This paper represents the first step in understanding this problem by reviewing the existing MVT studies contextualised within the theoretical frameworks developed in environmental criminology theories – originating in the West – and exploring to what extent they are relevant to the SA context. To achieve this, the paper has identified a range of key features in SA that are different from typical Western contexts, that could limit the appropriateness and capability of applying existing environmental criminology theories. Furthermore, despite these Western studies reviewed so far having introduced a number of explanatory variables for MVT rates, a range of significant elements are apparently absent in the current literature and this requires further analysis. For example, almost no attempts have been made to quantify the associations between the locations of vehicle theft, recovery of stolen vehicles, joyriding and traffic volume. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20criminology%20theories" title="environmental criminology theories">environmental criminology theories</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20vehicle%20theft" title=" motor vehicle theft"> motor vehicle theft</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia"> Saudi Arabia</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20analysis" title=" spatial analysis"> spatial analysis</a> </p> <a href="https://publications.waset.org/abstracts/44304/the-applicability-of-western-environmental-criminology-theories-to-the-arabic-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44304.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">298</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Public-Private Partnership in Tourism Development: Kuwait Experience within 2035 Vision</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Obaid%20Alotaibi">Obaid Alotaibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tourism and recreation have become one of the important and influential sectors in most of the modern economies. This sector has been accepted as one of the alternative sources of national income, employment, and foreign exchange. Kuwait has many potentialities in tourism and recreation, and exploitation of this leads to more diversification of the economy besides augmenting its contribution to the GDP. It is an import-oriented economy; it requires hard currencies (foreign exchange) to meet the import costs as well as to maintain stability in the international market. To compensate for the revenue fall stemmed from fluctuations in oil prices -where the agriculture, fisheries, and industrial sectors are too immune and inelastic- the only alternative solution is the regeneration of the tourism and recreation to surface. This study envisages the characteristics of tourism and recreation, the economic and social importance for the society, the physical and human endowments, as well as the tourist pattern and plans for promoting and sustaining tourism in the country. The study summarizes many recommendations, including the necessity of establishing authority or a council for tourism, linking the planning of tourism development with the comprehensive planning for economic and social development in Kuwait in the shadow of 2035 vision, and to encourage the investors to develop new tourist and recreation projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kuwait" title="Kuwait">Kuwait</a>, <a href="https://publications.waset.org/abstracts/search?q=public-private" title=" public-private"> public-private</a>, <a href="https://publications.waset.org/abstracts/search?q=partnership" title=" partnership"> partnership</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=2035%20vision" title=" 2035 vision"> 2035 vision</a> </p> <a href="https://publications.waset.org/abstracts/117057/public-private-partnership-in-tourism-development-kuwait-experience-within-2035-vision" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117057.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Developing and Validating an Instrument for Measuring Mobile Government Adoption in Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sultan%20Alotaibi">Sultan Alotaibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Dmitri%20Roussinov"> Dmitri Roussinov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many governments recently started to change the ways of providing their services by allowing their citizens to access services from anywhere without the need of visiting the location of the service provider. Mobile government (M-government) is one of the techniques that fulfill that goal. It has been adopted by many governments. M-government can be defined as an implementation of Electronic Government (E-Government) by using mobile technology with the aim of improving service delivery to citizens, businesses and all government agencies. There have been several research projects developing models to understand the behavior of individuals towards the adoption of m-government. This paper proposes a model for adoption of m-government services in Saudi Arabia by extending Technology Acceptance Model (TAM) by introducing external factors. This paper also reports on the development of a survey instrument designed to measure user perception of mobile government acceptance. A survey instrument has been developed by using existing scales from prior instruments and a pilot study has been conducted by distributing the survey to 33 participants. As a result, a survey instrument has been refined to retain 43 items. The results also showed that the reliabilities of all the scales in the survey instrument are above the levels acceptable in current academic research, thus the instruments developed by us are capable of analyzing the factors in M-government adoption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TAM" title="TAM">TAM</a>, <a href="https://publications.waset.org/abstracts/search?q=m-government" title=" m-government"> m-government</a>, <a href="https://publications.waset.org/abstracts/search?q=e-government" title=" e-government"> e-government</a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a>, <a href="https://publications.waset.org/abstracts/search?q=acceptance" title=" acceptance"> acceptance</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20government" title=" mobile government"> mobile government</a> </p> <a href="https://publications.waset.org/abstracts/47469/developing-and-validating-an-instrument-for-measuring-mobile-government-adoption-in-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47469.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">249</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Substation Automation, Digitization, Cyber Risk and Chain Risk Management Reliability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Serzhan%20Ashirov">Serzhan Ashirov</a>, <a href="https://publications.waset.org/abstracts/search?q=Dana%20Nour"> Dana Nour</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafat%20Rob"> Rafat Rob</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Alotaibi"> Khaled Alotaibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There has been a fast growth in the introduction and use of communications, information, monitoring, and sensing technologies. The new technologies are making their way to the Industrial Control Systems as embedded in products, software applications, IT services, or commissioned to enable integration and automation of increasingly global supply chains. As a result, the lines that separated the physical, digital, and cyber world have diminished due to the vast implementation of the new, disruptive digital technologies. The variety and increased use of these technologies introduce many cybersecurity risks affecting cyber-resilience of the supply chain, both in terms of the product or service delivered to a customer and members of the supply chain operation. US department of energy considers supply chain in the IR4 space to be the weakest link in cybersecurity. The IR4 identified the digitization of the field devices, followed by digitalization that eventually moved through the digital transformation space with little care for the new introduced cybersecurity risks. This paper will examine the best methodologies for securing the electrical substations from cybersecurity attacks due to supply chain risks, and due to digitization effort. SCADA systems are the most vulnerable part of the power system infrastructure due to digitization and due to the weakness and vulnerabilities in the supply chain security.

While there is a growing body of research exploring these systemic changes in urban environments, there is very little published research regarding rural schools. In fact, rural schools are still under-examined globally comparing to their urban and suburban counterparts over a range of reform dimensions. In Saudi Arabia, there are around 1128 rural areas that contain about 3200 schools. Several challenges face rural schools, especially in relation to recruitment, retention, and professional development opportunities for teachers and school leaders. However, there is very little in depth research which explores these issues “on the ground”. The aim of this research is fill this knowledge gap and explore teachers’ and leaders’ perceptions and experiences of working in rural schools in KSA. In Saudi Arabia, there is a growing body of research into school leadership. However, there is very little published research specifically exploring rural schools. By using an in-depth case study approach and adopting an analytical framework based on the interlinking concepts of leadership practices, culture, and CPD, this study offers and significant and original contribution to knowledge in this area. This study also will adopt a qualitative multiple case studies, which is going to employ semi-structured interviews, focus groups, and documentary analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leadership%20practice" title="leadership practice">leadership practice</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20culture" title=" school culture"> school culture</a>, <a href="https://publications.waset.org/abstracts/search?q=continuing%20professional%20development" title=" continuing professional development"> continuing professional development</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20school" title=" rural school"> rural school</a> </p> <a href="https://publications.waset.org/abstracts/151397/rural-education-in-saudi-arabia-school-leaders-and-teachers-experiences-and-perceptions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151397.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">81</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Pregnancy Rhinitis Prevalence among Saudi Women</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20G.%20Alotaibi">Mohammed G.

Therefore, our study was designed to evaluate the prevalence, triggering factors, severity and progression of rhinitis during pregnancy. Methods: Prospective cross-sectional study was conducted in eight governmental and private medical centers in Riyadh, Saudi Arabia, during June and July 2014. Validated Arabic language self-administered questionnaire was used. Sample size of 260 Saudi pregnant women was calculated by Raosoft sample size calculator. Random sampling was achieved by choosing one and skipping every five patients in the clinic list. Data were coded and entered manually into spreadsheets then transferred to SPSS statistical package version 16.0 for Windows. Consent, Privacy and confidentiality of information were assured. Results: Pregnancy rhinitis was reported 31.2% (CI 25.6 - 37.2%). Symptoms arising in first trimester appeared in 79.2% of PR cases and mostly worsen. The most prevalent symptoms were nasal pruritis (67.5%), followed by sneezing (57.1%), congestion (50.6%), and post nasal drip (46.7%). The major triggering factor was dust (71.4%), followed by Tobacco/Shisha smoke (57.6%) and perfume(47%). Preexisting allergic diseases were markedly associated with developing pregnancy rhinitis. Conclusion: Rhinitis during pregnancy manifested in one third of Saudi pregnant ladies. Nasal pruritus was the most common symptom and dust was the widespread triggering factor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allergy" title="allergy">allergy</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhinitis" title=" Rhinitis"> Rhinitis</a>, <a href="https://publications.waset.org/abstracts/search?q=sneezing" title=" sneezing"> sneezing</a> </p> <a href="https://publications.waset.org/abstracts/56954/pregnancy-rhinitis-prevalence-among-saudi-women" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56954.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">251</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Identification of Social Responsibility Factors within Mega Construction Projects </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Alotaibi">Ali Alotaibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Francis%20Edum-Fotwe"> Francis Edum-Fotwe</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Price%20%2F"> Andrew Price /</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mega construction projects create buildings and major infrastructure to respond to work and life requirements while playing a vital role in promoting any nation’s economy. However, the industry is often criticised for not balancing economic, environmental and social dimensions of their projects, with emphasis typically on one aspect to the detriment of the others. This has resulted in many negative impacts including environmental pollution, waste throughout the project lifecycle, low productivity, and avoidable accidents. The identification of comprehensive Social Responsibility (SR) indicators, which combine social, environmental and economic aspects, is urgently needed. This is particularly the case in the context of the Kingdom of Saudi Arabia (KSA), which often has mega public construction projects. The aim of this paper is to develop a set of wide-ranging SR indicators which encompass social, economic and environmental aspects unique to the KSA. A qualitative approach was applied to explore relevant indicators through a review of the existing literature, international standards and reports. A list of appropriate indicators was developed, and its comprehensiveness was corroborated by interviews with experts on mega construction projects working with SR concepts in the KSA. The findings present 39 indicators and their metrics, covering 10 economic, 12 environmental and 17 social aspects of SR mapped against their references. These indicators are a valuable reference for decision-makers and academics in the KSA to understand factors related to SR in mega construction projects. The indicators are related to mega construction projects within the KSA and require validation in a real case scenario or within a different industry to demonstrate their generalisability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20responsibility" title="social responsibility">social responsibility</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20projects" title=" construction projects"> construction projects</a>, <a href="https://publications.waset.org/abstracts/search?q=economic" title=" economic"> economic</a>, <a href="https://publications.waset.org/abstracts/search?q=social" title=" social"> social</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental" title=" environmental"> environmental</a>, <a href="https://publications.waset.org/abstracts/search?q=indicators" title=" indicators"> indicators</a> </p> <a href="https://publications.waset.org/abstracts/102940/identification-of-social-responsibility-factors-within-mega-construction-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102940.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Investigation of the Effects of Gamma Radiation on the Electrically Active Defects in InAs/InGaAs Quantum Dots Laser Structures Grown by Molecular Beam Epitaxy on GaAs Substrates Using Deep Level Transient Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Al%20Huwayz">M.

However, one of the difficulties with these structures is that electrically active defects can lead to serious issues in the performance of these devices. It is therefore essential to fully understand the types of defects introduced during the growth and/or the fabrication process. In this study, the effects of Gamma radiation on the electrically active defects in p-i-n InAs/InGaAsQDs laser structures grown by Molecular Beam Epitaxy (MBE) technique on GaAs substrates were investigated. Deep Level Transient Spectroscopy (DLTS), current-voltage (I-V), and capacitance-voltage (C-V) measurements were performed to explore these effects on the electrical properties of these QDs lasers. I-V measurements showed that as-grown sample had better electrical properties than the irradiated sample. However, DLTS and Laplace DLTS measurements at different reverse biases revealed that the defects in the-region of the p-i-n structures were decreased in the irradiated sample. In both samples, a trap with an activation energy of ~ 0.21 eV was assigned to the well-known defect M1 in GaAs layers <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quantum%20dots%20laser%20structures" title="quantum dots laser structures">quantum dots laser structures</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20radiation" title=" gamma radiation"> gamma radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=DLTS" title=" DLTS"> DLTS</a>, <a href="https://publications.waset.org/abstracts/search?q=defects" title=" defects"> defects</a>, <a href="https://publications.waset.org/abstracts/search?q=nAs%2FIngaAs" title=" nAs/IngaAs"> nAs/IngaAs</a> </p> <a href="https://publications.waset.org/abstracts/141942/investigation-of-the-effects-of-gamma-radiation-on-the-electrically-active-defects-in-inasingaas-quantum-dots-laser-structures-grown-by-molecular-beam-epitaxy-on-gaas-substrates-using-deep-level-transient-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141942.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">187</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Effect of Rapid Thermal Annealing on the Optical Properties of InAs Quantum Dots Grown on (100) and (311)B GaAs Substrates by Molecular Beam Epitaxy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amjad%20Almunyif">Amjad Almunyif</a>, <a href="https://publications.waset.org/abstracts/search?q=Amra%20Alhassni"> Amra Alhassni</a>, <a href="https://publications.waset.org/abstracts/search?q=Sultan%20Alhassan"> Sultan Alhassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Al%20Huwayz"> Maryam Al Huwayz</a>, <a href="https://publications.waset.org/abstracts/search?q=Saud%20Alotaibi"> Saud Alotaibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulaziz%20Almalki"> Abdulaziz Almalki</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Henini"> Mohamed Henini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of rapid thermal annealing (RTA) on the optical properties of InAs quantum dots (QDs) grown at an As overpressure of 2x 10⁻⁶ Torr by molecular beam epitaxy (MBE) on (100) and (311)B GaAs substrates was investigated using photoluminescence (PL) technique. PL results showed that for the as-grown samples, the QDs grown on the high index plane (311)B have lower PL intensity and lower full width at half maximum (FWHM) than those grown on the conventional (100) plane. The latter demonstrates that the (311)B QDs have better size uniformity than (100) QDs. Compared with as-grown samples, a blue-shift was observed for all samples with increasing annealing temperature from 600°C to 700°C. For (100) samples, a narrowing of the FWHM was observed with increasing annealing temperature from 600°C to 700°C. However, in (311)B samples, the FWHM showed a different behaviour; it slightly increased when the samples were annealed at 600°C and then decreased when the annealing temperature increased to 700°C. As expected, the PL peak intensity for all samples increased when the laser excitation power increased. The PL peak energy temperature dependence showed a strong redshift when the temperature was increased from 10 K to 120 K. The PL peak energy exhibited an abnormal S-shape behaviour as a function of temperature for all samples. Most samples exhibited a significant enhancement in their activation energies when annealed at 600°C and 700°C, suggesting that annealing annihilated defects created during sample growth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RTA" title="RTA">RTA</a>, <a href="https://publications.waset.org/abstracts/search?q=QDs" title=" QDs"> QDs</a>, <a href="https://publications.waset.org/abstracts/search?q=InAs" title=" InAs"> InAs</a>, <a href="https://publications.waset.org/abstracts/search?q=MBE" title=" MBE"> MBE</a> </p> <a href="https://publications.waset.org/abstracts/141819/effect-of-rapid-thermal-annealing-on-the-optical-properties-of-inas-quantum-dots-grown-on-100-and-311b-gaas-substrates-by-molecular-beam-epitaxy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141819.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">175</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> The Impact of Water Resources on Economic and Social Development in Kuwait</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Obaid%20Alotaibi">Obaid Alotaibi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The geographical location of the State of Kuwait contributed significantly to the suffering of Kuwait in the past, due to the scarcity of natural water resources and the inability of the State's financial resources to provide other water resources to meet the needs of the population. The problem of water scarcity in Kuwait remained until the beginning of the second half of the twentieth century, as the country's economic conditions revived with the emergence and export of oil; which was clearly reflected in the steady growth of the population. To cope with this population, increase, it was necessary to expand the various development programs to include all sectors of the state. The process of development and urbanization could not start without finding solutions to the problem of water shortage in Kuwait. The only option for officials to meet the needs of the population and the different sectors of water development is the desalination of seawater. This process necessitated the establishment of six desalination plants along the coast of Kuwait and extended freshwater arteries to reach everywhere on the land. However, this does not mean that the problem of water shortage has been completely solved. The desalination plants are not meeting the country's future water needs, especially considering the increasing population growth. These stations are nearing completion and they need to be replaced, renovation and maintenance, require significant expenses. Therefore, it was necessary for scientific research to address the issue of water in Kuwait, whether in the field of development of existing resources or in the field of rationalization of consumption and protection of available resources. The study focused on how to address the increasing demand for water resulting from population increase, the impact of water on economic and social development, the prospects of water resources in Kuwait and its ability to meet the needs of the country by 2030. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic" title="economic">economic</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuwait" title=" Kuwait"> Kuwait</a>, <a href="https://publications.waset.org/abstracts/search?q=social" title=" social"> social</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resources" title=" water resources"> water resources</a> </p> <a href="https://publications.waset.org/abstracts/102561/the-impact-of-water-resources-on-economic-and-social-development-in-kuwait" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102561.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> The Impact of COVID-19 on the Mental Health of Residents of Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaleel%20Alyahya">Khaleel Alyahya</a>, <a href="https://publications.waset.org/abstracts/search?q=Faizah%20Alotaibi"> Faizah Alotaibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The coronavirus disease 19 (COVID-19) pandemic has caused an increase in general fear and anxiety around the globe. With the public health measures, including lockdown and travel restrictions, the COVID-19 period further resulted in a sudden increase in the vulnerability of people too ill mental health. This becomes greater among individuals who have a history of mental illness or are undergoing treatment and do not have easy access to medication and medical consultations. The study aims to measure the impact of COVID-19 and the degree of distress with the DASS scale on the mental health of residents living in Saudi Arabia. The study is a quantitative, observational, and cross-sectional conducted in Saudi Arabia to measure the impact of COVID-19 on the mental health of both citizens and residents of Saudi Arabia during pandemics. The study ran from February 2021 to June 2021, and a validated questionnaire was used. The targeted population of the study was Saudi citizens and non-Saudi residents. A sample size of 800 participants was calculated with a single proportion formula at 95% level of significance and 5% allowable error. The result revealed that participants who were always doing exercise experienced the lowest level of depression, anxiety, and stress. The highest prevalence of severe and extremely severe depression was among participants who sometimes do exercise at 53.2% for each. Similar results were obtained for anxiety and stress, where the extremely severe form was reported by those who sometimes did exercise at 54.8% and 72.2%, respectively. There was an inverse association between physical activity levels and levels of depression, anxiety, and stress during the COVID-19. Similarly, the levels of depression, anxiety, and stress differed significantly according to the exercise frequency during COVID-19. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mental" title="mental">mental</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=pandemic" title=" pandemic"> pandemic</a>, <a href="https://publications.waset.org/abstracts/search?q=lockdown" title=" lockdown"> lockdown</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a> </p> <a href="https://publications.waset.org/abstracts/151998/the-impact-of-covid-19-on-the-mental-health-of-residents-of-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151998.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">103</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Power System Cyber Security Risk in the Era of Digital Transformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafat%20Rob">Rafat Rob</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Alotaibi"> Khaled Alotaibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Dana%20Nour"> Dana Nour</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Albadrani"> Abdullah Albadrani</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulmohsen%20Mulhim"> Abdulmohsen Mulhim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Power systems digitization solutions provides a comprehensive smart, cohesive, interconnected network, extensive connectivity between digital assets, physical power plants, and resources to form digital economies. However, digitization has exposed the classical air gapped power plants to the rapid spread of cyber threats and attacks in the process delaying and forcing many organizations to rethink their cyber security policies and standards before they can augment their operation the new advanced digital devices. Cyber Security requirements for power systems (and industry control systems therein) demand a new approach, unique methodology, and design process that is completely different to Cyber Security measures designed for the IT systems. In practice, Cyber Security strategy, as applied to power systems, tends to be closely aligned to those measures applied for IT system purposes. The differentiator for Cyber Security in terms of power systems are the physical assets and applications used, alongside the ever-growing rate of expansion within the industry controls sector (in comparison to the relatively saturated growth observed for corporate IT systems). These factors increase the magnitude of the cyber security risk within such systems. The introduction of smart devices and sensors along the grid initiate vulnerable entry points to the systems. Every installed Smart Meter is a target; the way these devices communicate with each other may instigate a Denial of Service (DoS) and Distributed Denial of Service (DDoS) attack. Attacking one sensor or meter has the potential to propagate itself throughout the power grid reaching the IT network, where it may manifest itself as a malware infiltration. <p
