ABSTRACT
In this paper, a review of the current status and future perspectives for reinforced glass fiber waste is undertaken, as well as an evaluation of the management hierarchy for these end-of-life materials. Waste levels are expected to increase in the coming years, but an improvement of collection routes is still necessary. The recycling processes for these materials are presented. The associated advantages and disadvantages, as well as the corresponding mechanical characteristics, are described. Although mechanical shredding is currently the most used process, there is a potential for thermal processes to be more competitive than others due to the fiber quality after the recycling process. However, the energy requirements of each of the processes are not yet well explained, which compromises the determination of the economic value of the recycled fibers when included in other products, as well as the process feasibility. Nevertheless, the work of some authors that successfully integrated recycled glass fibers into other elements with increased mechanical properties is evaluated. Future recommendations for the recycling of glass fiber and its commercialization are made.
ABSTRACT
Objectives: The objective of this study focused on several issues. Firstly, on the fight against corruption through the improvement of the control of public accounts;secondly, on the monitoring carried out by the public compliance sector and, finally, on the promotion of blockchain technology for data mining and government contracts to avoid a system in which corruption prevails due to lack of transparency. Methodology: The method followed for the realization of this scientific work has been analytical, which has been supported by doctrine, legislation and analysis of reports on the impact of Covid-19 in Brazil and Colombia. Results: This scientific work has shown that in order to guarantee a dignified life, health must be considered as the central axis, so that when there is poor management, this has repercussions on citizens, since it causes overload and imbalances in hospitals. In addition, it is proven that there is corruption in the system and this causes a malfunction of public services. On many occasions, there are suspicious purchases and contracts with the Public Administration due to lack of transparency and public control, negatively impacting on legal certainty and democratic stability. Contributions: The contribution of the research consists of presenting the negative impacts of corruption during the Covid-19 pandemic, as well as pointing out the implementation of blockchain technology for the control of public accounts. © 2021, Centro Universitario Curitiba - UNICURITIBA.

ABSTRACT
Objectives: The instant work investigates the effects of the COVID-19 pandemia on Brazilians entrepreneur, through analysis of two premises: (i) in 2020, the number of judicial reorganization requests would increase exponentially;(ii) the legislative measures promulgated by law #14,112/2020 upon law #11,101/2005, especially, the financing to debtors under judicial reorganization, would be useful and effective to the utilization of judicial recovery as a means of maintaining and preserving the company. Methodology: The deductive method was adopted, as from document research, as well as from analysis of data collected by other official statistical surveys and economic measurements. Results: It is appropriate to state that the sanitary measures for pandemia containment have deeply affected Brazilian entrepreneurs. However, the number of judicial reorganization requests has not increased, as expected, and the changes implemented upon bankruptcy legislation, as to debtor financing, have not yet proven efficient to foster the use of judicial reorganization. Contributions: Despite legal incentives created on behalf of debtor financing under judicial reorganization, there still is a high reputational cost to the entrepreneur which avails itself of this tool, turning the credit granted to this grantee more financially burdensome, on account of regulatory motivations. Finally, it can be mentioned that a judicial recovery request implies, to the debtor, the taking up of several obligations representing a significant tranche of expenses to the entrepreneur in distress, thereby discouraging such requests. © 2021, Centro Universitário Curitiba - UNICURITIBA.
