Prevalence of Flat Foot and high arch foot among undergraduate physical therapy students by using Navicular Drop test[ ]


Flatfoot is defined as depressed or lack of medial longitudinal arch, along with a valgus heel or not, rather than as a diagnosis of the hidden root cause. This account for diseased or non-diseased, rigid or flexible, and painful or pain free status. Flexible flatfoot in most cases is a physiological variant rather than a pathological condition. It encounters almost all new born and is frequently found in kids and youth. In reality the medial longitudinal arch formulates during the first 10 years of life. Many precipitating factors play important role in flexible flatfoot, together with hereditary, widespread ligamentous slackness, increased BMI in addition to type of shoe- wearing in early infancy.

Modeling of a cylindro-parabolic solar collector and simulation by Matlab software[ ]


The objective of this study is the use of a cylindro-parabolic solar concentrator in the transformation of solar energy into thermal energy. The reflector and the absorber used have a specific geometrical shape of 2m in length, 2cm in thickness and 6cm in width. A mathematical approach is made by the MATLAB software, of which we simulated a theoretical calculation applied to the dimension proposed to the system studied[12]. The parameters studied in the form of the equations in our simulation are the inlet and outlet temperature in the heat coolant fluid, the absorber and glass temperature, the irradiation flux, and the tilt factor[4].This study also aims at the modeling of the heat transfer of a cylindrical-parabolic solar collector with the values of daily sunshine in Morocco. In addition, we have studied more particularly the solar energy which makes it possible to recover the heat of this solar radiation within a fluid [1-2].The results obtained by this simulation show a good correlation between the experimental curves by the dimensioned system and the theoretical values in the bibliography[8].

Focused Crawling Using Content Classification and Link Priority Estimation[ ]


Focused crawlers are used to crawl and index web pages that are specific to a given topic but due to this sheer amount of web pages and data generally, a large part of data gets ignored and various anchor tags are never indexed. In order to solve such problems, we propose an improved crawling technique by dividing current challenges into two modules and conquering them individually. We introduce a new weighing factor based on content blocks and mutual information to obtain relevant web pages. Further, we propose the use of Context graphs and content block partition technique in order to find relevant web links by using link priority calculator (LPC) based on cosine similarity. This paper illustrates experimentally that our focused crawler is better than other focused crawlers based on breadth-first, anchor text only and link-context only partition in terms of target recall. In conclusion, our proposed system is effective and efficient for focused crawling.

The International Experience in Implementing The New High School Education Program: Global Agendas, Issues, and Challenges in Vietnam[ ]


Making a change in public high school is essential in Vietnam, but it also fraught with challenges. Any ambitious new initiative is bound to have supporters, detractors, and obstacles to a seamless rollout.Today’s many Vietnam’s public high school and district leaders face a host of “issues”- many of them controversial-that demand immediate and ongoing attention. Among the most significant are: Transitioning to higher standards, aligning new assessments to the new standards, implementing teacher evaluation systems and managing budgets and spending with unprecedented restrictions. Education and teachers are of crucial importance in preparing young people and societies for the future. Education is strongest in those societies which value and support their teachers and public education systems. Teachers must take on new roles and responsibilities: they must be lifelong learners and help others to learn to know, to do, to be and, especially, to learn to live together and finally teachers must be intimately involved from the outset in the design of educational reforms, as well as in their implementation.Today’s learners are digital natives-yet they come to school and power down their devices. As public high school educators in Vietnam public high school, we need to embrace the power of technology to make learning relevant for all students and adults. Using technology effectively in everyday learning can help students to strengthen their learning experiences and build on their intuitive technology skills.
