http://ijaems.com/ Open Access international Journal to publish research paper en-us January It is critical to protect coastal and offshore structures. Most current studies and scientific investigations are centered on how to protect seashore with an efficient and cost-effective system. This study involved the testing of a new floating breakwater configuration (FB). A series of experiments were carried out in the lab of The Higher Institute of Engineering (El-shorouk City) on the new model and the traditional vertical plane FB without a curved face to compare their behaviours and performance in wave attenuation. The incident, reflected, and transmitted wave heights were measured, and the coefficients of reflection, transmission, and energy dissipation were calculated using these measurements. In terms of hydrodynamic performance, the curved-face floating breakwater outperformed the traditional vertical floating breakwater, according to the study's highlights. The curved face model significantly reduced wave transmission values when compared to the traditional vertical configuration. The greater the concavity of the curve, the better the model handles waves, especially when the wave steepness is low. http://ijaems.com/detail/the-hydrodynamic-performance-examination-of-a-new-floating-breakwater-configuration/ Yasser El Saie1, Ayman El Sayed2, Haitham Ehab3, Ahmed Balah4 http://ijaems.com/upload_images/issue_files/1IJAEMS-11220222-TheHydrodynamic.pdf The stability of fiscal revenue, so called the fluctuation of fiscal revenue, refers to the fluctuation degree of local government's actual fiscal revenue deviating from the expected fiscal revenue. As the main way of funds for local governments to perform public service functions, fiscal revenue is an important starting point for local governments to regulate and participate in economic activities. The drastic fluctuation of fiscal revenue will interfere with the government's economic functions, reduce the quantity and quality of public services, and produce inefficient government activities. The economic and social activities carried out by governments at all levels in practice are numerous and complicated, which can be classified according to different purposes and perspectives. However, no matter which classification method is adopted, stable financial revenue is the core guarantee of government economic activities, which is in the position of "leading the development and affecting the whole body". Based on the combination variance method of white (1983), this paper constructs the stability index of local fiscal revenue, and measures the stability of fiscal revenue of all provinces in China, and interprets and analyzes the measurement results through the theoretical method of economics. It is found that there are significant regional differences in the fluctuation of local fiscal revenue in China. By comparing the changes of fiscal revenue fluctuation index in 2000, 2009 and 2018, the fluctuation index of fiscal revenue shows obvious regional differences. The fluctuation degree of the economically developed eastern coastal area is lower than that of the underdeveloped central and Western Region, and the southern region with lower economic activity is significantly lower than that of the north. On the other hand, the external shocks such as "replacing business tax with value-added tax" and financial crisis also have a positive impact on local tax fluctuations. Through the analysis of the experimental results, it is found that good economic foundation, capital accumulation, industrial structure and geographical location have a great impact on financial stability. Therefore, the government should pay attention to the gap between the stability of fiscal revenue in different regions, actively improve the economic foundation of the poor stability of the central and western regions, formulate differentiated economic and financial policies, vigorously develop the secondary and tertiary industries, and improve the stability of fiscal revenue to cope with regional economic risks and improve the administrative efficiency of the government. http://ijaems.com/detail/measurement-and-analysis-of-the-stability-of-local-fiscal-revenue/ Yu Fengze http://ijaems.com/upload_images/issue_files/2IJAEMS-0120231-Measurement.pdf Radiology is a medical specialty that renews itself and advances every day, in a process of modernization that, in addition to investments, requires a continuous effort to update. The use of radiological images is a fundamental part of learning because of its availability and undeniable clinical relevance. Thus this study will make it possible to review how the teaching and learning of radiology and diagnostic imaging in medical education is developed in an integrated and interdisciplinary undergraduate curriculum in medicine. Objective: To identify the importance of radiology and diagnostic imaging in undergraduate medical education in a curriculum using active methodologies. Methodology: The present study is a systematic literature review, therefore it does not require ethics committee approval, it was carried out from a screening of articles in the period from January 2011 to March 2021 from two electronic databases: PubMed and Science Direct. The descriptors used in the search were "radiology" AND "medical education". Academic articles were searched for authors who correlated Active Methodologies, Medical Education, Transversal Teaching in Medical Graduation, Radiology and Diagnosis. Results and Discussion: Studies that had Active Methodologies, Medical Education or Radiology and diagnosis were included in this review, as well as literature review studies that accounted for 05 articles and editorials. To better understand the role of radiology in medical practice, it is necessary to review its history in medicine. Since the advent of imaging exams, radiology and diagnostic imaging have presented important advances in several areas. Its implementation in the curriculum was addressed by the author AL QAHTANI et al, 2014, in which he pointed out the importance of a cross-curriculum for the insertion of the axis of this skill and not only a discipline in a single period of the course, because the content is related to other areas of Medicine, such as Medical Pathology, Human Anatomy and Emergency and Urgent Care.With all this mentioned, it should be understood that the teaching environment should be seen as a place of individual and collective transformation, being receptive to new methodologies and new approaches to teaching and insertion of new skills to the students. http://ijaems.com/detail/radiology-and-imaging-diagnosis-in-undergraduate-medicine-in-a-curriculum-using-active-methodologies-a-systematic-review-from-2011-to-2021/ Vera Lúcia Lameira Picanço, Guilherme Alves Da Silva, Tainá Marques De Sousa Ferreira, Juliana Saraiva Gomes, Rita De Cássia Barroso Tavares, Marcos Alberto Figarella De Oliveira, Brenda Michelly Da Silva Carvalho, Juliana Saraiva Gomes, Rita De Cássia Barroso Tavares, Maria Tereza Dias Ferreira, Giovana Duarte Pereira, Hanna Kainã Rocha Souza Adão, Gabriel Carvalho De Oliveira, Samuel João Dos Santos Santana, Ingrid De Paula Costa Pereira, Jaíne Cardoso Da Silva, Maria Jéssica Alves Pinheiro, Heloisa Pamplona Boulhosa, Adrianne Raposo Ponte, Camylla Rebbeca Bezerra De Aragão, Edilson Pamplona Boulhosa, Bruno Henrique Da Silva, Enzo Lobato Da Silva, Matheus Albert De Souza Puerro, Carolina Donadio De Oliveira, Luíza Pinheiro Nascimento, Yorhanna de Morais Cardoso, Ana Laura Nobre e Nobre, Lucian Herlan da Costa luz Fernandes Gabriela Mutran dos Anjos, Luciana Saliba Mohana Alencar, Maria Clara Aguiar Guerra, Juliana Prusch Fernandes Cardoso, João Lucas Barbosa Nery Marque, Dienyelle de Nazaré Costa Barbosa, Manuella Ferraz de Souza Monteiro, Joely Lúcia de Souza Rodrigues, Maria Vitória Pantoja Batista, Maria Clara Almeida Sadala Dos Santos, Patrícia Benitez Sousa, Daniel Rêgo Sousa, Antonio Paulo Favacho Furlan, Alain Patrick dos Santos Moreira, Brenda Vidigal Tavares Nunes, Elaine De Oliveira e Silva , Danielle Lima Barbosa, Carolynne Lima de Sousa, Gabriela Blanco de Morais Trindade , Carolina Vinagre Pires Franco http://ijaems.com/upload_images/issue_files/3IJAEMS-10120232-Radiology.pdf
