We studied the Comirnaty vaccine’s demand, supply, demand and supply elasticity and the strategic analysis that consisted of SWOT analysis and PESTEL analysis. Several factors, including the global spread pattern of COVID-19, the vaccine’s effectiveness, and the availability of alternative vaccines, drive the demand for Comirnaty. The supply of Comirnaty is influenced by factors such as manufacturing capacity and the development of new vaccines. The elasticity of demand for Comirnaty is high, with a significant increase in demand at lower prices and a decrease in demand at higher prices. Overall, the market for Comirnaty is complex and dynamic, with demand and supply being influenced by various factors. We expect a dramatic change in the market forces after the announced commercialisation of Comirnaty directly to the end consumer in the USA.Item الاتجاهات الحديثة في بحوث ودراسات التسويق الإلكتروني(October university for modern sciences and Arts (MSA), 2022) عبد الرحمن حجازي, رشاItem Reviewing the potentials of Mobile Media and Learning(October university for modern sciences and Arts (MSA), 2022) Marrie, HassanMedia technology presented in handheld devices, like mobile smartphones and tablets, enables the integration of immersive reality (Genlott et al., 2019). Kugler (2017) predicted that this will be at the forefront of mobile language learning. Taking a media studies approach, this thesis addresses the question of how mobile apps facilitate the engagement of independent language learners. Classical studies have restricted communication in learning traditionally in direct interaction between the knowledge provider and the learner in a fixed physical location. By introducing media technology to this setting, learning as a process of communication may adapt and change. New media products have emerged in the edutainment, e-learning and interactive learning markets (Okan, 2003). In other fields, mobile media apps offer features that may extend the horizon of engagement, as learners can immerse themselves in a semi-artificial world. Different mobile learning apps are also following this new technological trend of integrating engaging features into their design. This integration may pave the way for alternative possibilities for transforming learning. Learning a new language, is a multi-layered skill, and a challenge for any learner. For independent learners, additional factors can further complicate the task, such as social, financial and time constraints. These perceived restrictions may create a gap in pursuing continuous learning. Therefore, a systematic overview on learning as engagement with mobile media may initiate a better comprehension and assessment of the dynamic potentials of digital media.Item رؤية مستقبلية لتطوير بحث الصحافة الرقمية والأمن المعلوماتية(October university for modern sciences and Arts (MSA), 2022) محمد حسني عبدالله, ايمانتقدم الدراسة رؤية مستقبلية لتطوير بحوث الصحافة الرقمية والأمن المعلوماتي، بالاعتماد على منهجية التحليل من مستوى ثانٍ، للدراسات المعنية بهذا الحقل المعرفي في جميع أنحاء العالم في الفترة من 2017م إلى 2021م، وقد تم اختيار الدراسات بعينة عمدية قوامها 215 دراسة، بالاعتماد على عدد من قواعد البيانات الدولية، انطلاقًا من حتمية سعي باحثي علوم الاتصال والصحافة لاستكشاف ماهية الظاهرة وتطوراتها، نظرًا لتزايد الاحتياجات الأمنية للمؤسسات الصحفية المُعاصرة، خاصة الرقمية منها، وقد توصلت الدراسة إلى عدد من النتائج والتوصيات المُرتبطة بتطوير الاتجاهات البحثية للدراسات العربية في هذا الحقل المعرفي مع طرح رؤية مهنية لتطوير الأداء الصحفي، وأخرى أكاديمية لتطوير مقررات الأمن الرقمي وأمن المعلومات في كليات الإعلام.Item Optimization of Public Spaces Lost in Egyptian Urban Cities: The Under Bridges as a Case Study(October university for modern sciences and Arts MSA, 2022) Ahmed Youssef, HassanThe governorates of Cairo and Giza are considered one of the largest areas of the Arab Republic of Egypt which contain large numbers of bridges that link urban areas with each other. It is one of the important traffic arteries for solving traffic jam problems as a result lack of awareness to optimize these careless areas, they have become careless urban areas, dark and very dangerous places to collect garbage and wastes, also Places crime, spread Drugs, informal parking, and finally transgresses from street vendors.

This makes SM prone to channel irregularities like multipath Raleigh fading. Hence, employing and optimizing a transmit precoder (TPC) that matches the channel can enhance the SM bit error rate performance by increasing the Euclidean distance (ED) among all possible received vectors. However, it is common that optimization algorithms endure high complexity. Focusing on M-PSK constellation, and by reducing the number of Euclidean Distance constraints, we cut the complexity by nearly a factor of M. This is a significant reduction for high order constellations with a large value of M. This concept is shown to benefit any TPC optimization algorithm for SM and its variants. To further shrink the complexity, we introduce an optimization algorithm that minimizes the sum of the exponentials of negative EDs. The paper shows that the complexity can be reduced significantly without loss in performance.Item A Sustainable Management Model for New Egyptian Cities(October university for modern sciences and Arts MSA, 2022) Mahmoud Ouf, Yasser; alNahas, Nabil; Awad Gomaa, AhmedThis study aims to identify the mechanisms and frameworks for urban transformations required to achieve sustainable management in new Egyptian cities, achieving harmony and balanced interaction with the natural system in the context of social life, and rational resource management that meets current and future human needs while raising society's standard of living. Because of their efficiency in improving the management of new cities in Egypt, the study underlined the importance of adopting the guidelines as sequential measures for a sustainable urban environment management. The research has resulted in a model for long-term administration in new Egyptian cities, which contributes to the application of its concepts and principles in a balanced framework across all dimensions (political, administrative, and institutional) and recommends means for implementing these rules at the city level in order to establish sustainable urban communities concerned with enhancing the urban environment in order to accomplish Egypt's Vision 2030.Item Investigating Tool Wear, Chip Behaviour and Spring Back Action Using FEM(October university for modern sciences and Arts MSA, 2022) El-Hossainy, Tarek; Abdrabou, Mahmoud; Abdelkawy, AbdallahThe tool wear found in machining processes represents main obstacle for machinability due to its detrimental effects on surface roughness, material removal rate and machining economy. A nonlinear thermomechanical finite element model was developed to simulate the tool chip interaction. This model predicts not only the chip morphology and chip flow direction, cutting forces values, stress distribution, but also can use to predict tool wear. Furthermore, the effect of elastic deformation (spring back) and the thermal effect have been considered in the model. Cutting force was predicted and compared with the conducted experimental work. Dry turning operation was carried out on low carbon steel using carbide tool. The tool/workpiece interface stress on flank face was calculated and compared with the FEM. Predicted results show good correlation with the FEM. FE model was verified experimentally by measuring the cutting force. The friction on the flank face and spring back concentrates the stress on the flank face.Item WATER SCARCITY IN THE CONTEXT OF CHINA(MSA-Management science journal, 2022) Gamil, Amal; Abdelrashied, MahmoudIrrigated agriculture is crucial to China's food production, but it is in danger due to the country's growing water shortage. As a result, the main objective of this research is to improve knowledge of the evolving patterns in the balance between water supply and demand, their effects on food output, and governmental policy reactions. The environmental change increased water shortage in various river basins in northern China, which led to a decrease in irrigated land. decreased food production and regions. The study shows that China's water shortage is a regional problem, particularly in the north. Here restricted and unequal access to water resources, a drop in surface water supplies, and depletion are all examples of this deterioration of water quality, depletion of groundwater supplies, and rising water consumption. As a result, the Chinese government has attempted to regulate overall water consumption. extraction, increase water use effectiveness and reduce pollutants in the water. Although these legislative measures are encouraging, their efficiency in addressing China's growing water shortage needs to be investigated.Item Place Attachment as an Outcome of Placemaking and the Urban Quality of Life(October university for modern sciences and Arts MSA, 2022) Magdi Mohammed, Ibrahim; Ahmed Sadek, SadekPlacemaking is a hands-on approach. It is an overarching concept and a cumulative process that drives place users to take part in the process of reimagining and reinventing their public spaces, enhancing the effective bond between them and the places they share (place attachment). Furthermore, placemaking, identity, attachment are interrelated terms. This study aims to discuss and identify the relationship between these terms and the urban quality of life. It depends on a deductive method to conclude place attachment attributes and the key performance indicators of the urban quality of life. To measure the impact of place attachment on the urban quality of life a questionnaire of Likert-type scale has been applied to a sample of 33 experts. Experts were asked 24 questions to measure the impact of each place attachment attributes on the key performance indicator of the urban quality of life; as a result, the indicators of the urban quality of life were arranged according to being affected by place attachment attributes. The main finding of this study is related to the process of enhancing the quality of urban life for a space/area. In the beginning, build up a physical identity for this space/area via involving the targeted users in the design of their places; and creating places that users can modify and adapt as the potential for individuals and community personalization. This involvement will enhance users' feelings of the place's character, raise people's sense of place/identity and drive them to attach to this place.Item A Proposed Model for Measuring the Performance of Urban Form’s Aesthetics(October university for modern sciences and Arts MSA, 2022) Nabil Ashry, Omar; Hanim Afifi, Eman; Sayed Abdelrasol, AhmedThe research discussed the theoretical concepts related to beauty in general and the aesthetics of urban formation in particular, which is concerned with the interpretation of sensory perception of the aesthetics of visual formation and the perception of the urban environment in its functional and intellectual dimensions. The research also discussed the different approaches to explain the visual formation or the image of the city, in order to derive the criteria for measuring the performance of the aesthetics of the urban formation of the city centre, which was based on the eleven Edinburgh criteria. The research added a new criterion representing modern technologies and smart materials to become twelve criteria. The research was able to analyse the main criteria into a set of sub-criteria with 76 criteria, then extract their characteristics and performance indicators (KPIs) for each criterion with a total of 291 indicators. The relative weights of these indicators were also calculated in a mathematical way based on the frequency of the indicator through the analysis of (9) experiments (including 5 global & 4 regional). These indicators were established to produce the proposed model for measuring the performance of the aesthetics of urban formation, which is the main objective of the research, and it was tested by applying it to the Egyptian experience on city centres of different generations represented in the 6th. of October, Al-Rehab, the New Administrative Capital and Madinaty. The performance ratios were: Al-Rehab 81.69%, and the New Capital 80.70%, Madinaty 69.35%, and 6th. of October 69.00%.Item Redefining the Secondary Egyptian Cities : An Assessment Study for the Global and Local Definition to Achieve Balanced Development.(October university for modern sciences and Arts MSA, 2022) Ibrahim Youssef, Akram; Mohammed Mostafa, Ayman; Ahmed Amer, IsmailSecondary cities affect urban development for developed and developing countries, as they consider transitional zones for various activities between the rural settlements and primate cities. Therefore, the world has struggled to set criteria for defining the secondary cities understanding their intermediate role within the urban system. On the other side, the local experience has followed other criteria for determining the secondary Egyptian cities, which are entirely different from the global trend and may not achieve balanced development. Accordingly, this research attempts to assess the local definition of secondary cities by investigating to what extent they differ from the global terminology and how this difference affects them. The study firstly indicates the difference in defining the secondary cities from an international and national perspective. Subsequently, it discusses the effect of the local definition on achieving a physical hierarchy between cities. Then, it compares the ability of primate and secondary cities to achieve efficient resources mobilization equal to their population size and available opportunities; consequently, this comparison adds another layer of assessing the local definition. Finally, the research suggests a concept to redefine the secondary Egyptian cities based on the global defining to help the secondary Egyptian cities attain balanced development.Item الاتجاهات الحديثة في بحوث ضوابط وأخلاقيات التسويق الإلكتروني(October university for modern sciences and Arts (MSA), 2022) Ezz El Din, Shaimaaتنتمي هذه الدراسة إلى دراسات تحليل المستوى الثاني Meta-Analysis، وقد اعتمدت الباحثة على أسلوب «التحليل من المستوى الثاني Meta-Analysis» لمراجعة التراث العلمي من الدراسات السابقة منذ عام 2015 حتى عام 2021، لتحليلها تحليلًا نقديًّا، بالاعتماد على عينة متاحة باللغتين العربية والإنجليزية، للوقوف على التطورات المتلاحقة في التسويق الإلكتروني، بالتركيز على الاتجاهات الحديثة. وقد استهدفت الدراسة رصد وتوصيف وتحليل الاتجاهات الحديثة وأبرز الإشكاليات البحثية الخاصة بدراسات ضوابط وأخلاقيات التسويق الإلكتروني على مستوى بعض الدراسات العربية والأجنبية على اختلاف السمات البحثية، وكذلك التعرف على المناهج العلمية والأطر النظرية المستخدمة في مجال دراسات ضوابط وأخلاقيات التسويق الإلكتروني بغرض تقديم رؤية نقدية للتراث العلمي في ذلك المجال، وأخيرًا تقديم رؤية مستقبلية واقتراح أجندة بحثية لتطوير الدراسات في مجال ضوابط وأخلاقيات التسويق الإلكتروني. وقد تبين التنوع في الموضوعات والقضايا البحثية، والأطر النظرية والمناهج المستخدمة وأدوات الدراسة والعينات، وذلك على مستوى المدارس البحثية الأجنبية المختلفة، ومن الملاحظ أيضًا وجود تطور في الدراسات المصرية والعربية، ولكن هناك حاجة لمزيد من التطوير في محاولة لسد الفجوة المعرفية في موضوع الدراسة الحالي، من خلال تقديم رؤية مستقبلية للتطوير.Item EMERGENCY LOCATIONS PROBLEMS WITH STOCHASTIC PARAMETERS(MSA-Management science journal, 2022) Tharwat, Assem A.; El-Khodary, Ihab A.
