USE OF BLOCKCHAIN ​​FOR REGISTRATION

 One of the main discussions about the usefulness of Blockchain for education concerns the registration of diplomas. The diploma is considered one of the most important documents issued by educational institutions (GRECH and CAMILLERI, 2017). The diploma serves as a document proving the training received by the student and gives him the necessary authorization to exercise his profession.


Currently, there is a growing search for courses in the Distance Education (EAD) modality, so that such courses can be offered, it is necessary to make a wide use of IT resources in Education (PAULA et al., 2018). The entire EAD process takes place through virtual learning environments (VLE), including the availability of the student's diploma at the end of the course. However, there are several cases of forgery of diplomas and this can compromise the credibility of educational institutions and even put the lives of people at risk, by placing unskilled professionals in the market. In this context, it is necessary to implement more robust security mechanisms to give greater reliability to the process of issuing and validating diplomas (GALLARDO; BAZAN and VENOSA, 2019).


According to Harthy; Shuhaimi and Ismaily (2019) it is possible to use Blockchain to ensure better security for the issuance of diplomas, ensuring that they can be validated by any interested person, at any time. The authors present four recommendations, which according to them, should be considered in general when using Blockchain in educational institutions:


Define the conditions for the execution of the Blockchain . It is necessary that the nodes are executed on machines that guarantee an adequate processing power to the application.

Define which cryptographic method will be used . You must know the algorithm that will perform the hash calculation of the blocks. The most widely used is SHA256, which transforms a large number of information into a hexadecimal numeric sequence of fixed size.

Define the rules for using Smart Contracts . If the application makes use of Smart Contract, it is necessary to define its implementation and execution rules clearly.

Desktop Support Technician is known as one of the backbones of IT organization. They are also accountable for groundwork, installation, and maintenance of end user workstation equipment (laptops/ desktops) and additional peripherals including IP telephones.

Transaction tracking . It is necessary to guarantee the traceability of all transactions that occurred on the network and of all nodes that have been mined. However, the work does not present implementations illustrating the feasibility of using Blockchain, which reduces the understanding of how this solution could be used in practice.

For Kolvenbach; Ruland and Grather (2018) it is possible to develop a blockchain-based platform to control the issuance and validation of diplomas and certificates due to the high level of security presented by the network. The paper mentions existing Blockchain-based tools for this purpose: Blockcerts (MIT, 2016), developed by MIT, and TrueRec (BOESER, 2017), created by the SAP group.

How to study for such an assessment?

 Studying for this type of test requires discipline, focus, dedication and special preparation. Just as a student is qualified for the entrance exam, the candidate must train to do well in the proficiency test. This means  dedicating exclusive time to studies  and immersing yourself in the English language. See more:  Amazon Saheli Quiz Answers Each proficiency test, of course, requires  different preparation , due to its particularities. Among the activities recommended for those who wish to  study on their own  are: redoing questions from previous exams, reading a lot of texts in English, training each of the tested skills. In addition, the candidate for certification must even prepare to complete each stage in the stipulated period, that is, train to perform the tests within the predetermined time limits. It is also important to deepen your studies, going beyond the specific vocabulary of your area. It is also essential to prepare yourself taking into account several aspects of the

Starting your computer for the first time - important points

So you've got your new computer and are ready to get started. When all the components of the computer are nearby, not connected to each other, a bunch of different wires around, it may seem that you will not be able to cope with this task. There is really no reason to panic. The first startup of the computer will proceed as planned. In most cases, a small manual on how to connect it comes with the computer. But, even if there is no such instruction, you can still piece together all the devices of your computer yourself in just a few simple steps . Preparing to launch the laptop If you bought a laptop or netbook , the preparation procedure before the first launch will take less than a minute. On some models it may be necessary to connect the battery. When the battery is in place, open the cover and press the power button. If the battery is not charged, you will need to connect the AC adapter that came with your laptop. You can continue to work while charging. If you need to connect

Natural Language Processing (PLN)

 Natural Language Processing (PLN) is an aspect of Artificial Intelligence (AI) that helps computers process and manipulate human language. The purpose of PLN is to serve as a bridge between the way humans communicate and understanding machines.   As much as the current applications of PLN suggest that it is a new technology, studies began in the 40s, through the creation of Machine Translation , which intended to differentiate languages ​​and adapt the syntax. In the following decade, Noam Chomsky published a theory on the generative capacity of languages ​​that brought computational and linguistic studies together.   Now that we’ve answered the question of what is SOW , it’s time to discuss the objective. The objective, or scope statement, clearly identifies the project’s objective and purpose.  From then on and until the mid-90s, studies aimed to adapt systems that perform tasks guided by dialogues, solve problems and deal with linguistic ambiguities.   For us, who are used to using
