Corporate social responsibility in times of crisis: business actions during the COVID-19 pandemic
Get PDFBetween the years 2019 and 2020, humanity was affected by one of the most serious pandemics in recent history, caused by the severe acute respiratory syndrome virus 2 (SARS-CoV-2). The socioeconomic tragedy required the complete mobilization of governments, companies, and other organizations to contain and combat the disease. Shedding light on the role of companies, this article set out to analyze, through descriptive, qualitative and documentary research, the various manifestations of Corporate Social Responsibility in Brazilian companies during the pandemic, with the Agenda 2030 as a backdrop for Sustainable Development and related initiatives. It became evident that, while on the one hand, organizations are strongly invited to act in the containment of world events harmful to human life, by extension, socially responsible companies must bear the commitment to work together to mitigate the impacts of climate change and to eradicating hunger and poverty, equally urgent and necessary demands

Healthy lungs maintain a young and energetic body
Get PDFIn general, life is only possible in the presence of oxygen in a form that can be easily absorbed by the body. In the case of humans, the lungs have as their main task the provision of the oxygen necessary for the body to carry out daily activities. The lung is a paired organ located in the chest cavity, a fibro-elastic organ capable of altering your volume during breathing (inspire and expire). The weight of a lung varies between 800 and 1,000 grams, of which more than 50% is blood. The air reaches the lungs through a pipeline system consisting of Nazo-pharynx, larynx, trachea, bronchi, and bronchiole. The role of the piping system is to heat and dampen the air or to capture and remove foreign inhaled particles. The channel system decreases in diameter after each branch - from the trachea and the large bronchi to the bronchiole with a diameter of less than one millimeter. The lung consists of over 30 different cell types. Trachea and large bronchi are taped by a mucous layer containing multiple cell types: ciliary cells - provides mucus movement, caliciform cells - secretes mucus, basal cells - plays a role in regeneration and neuro-ectodermic cells - ensures the secretory function of the lungs. In the chorion (the deep layer beneath the mucosa) there are cells involved in the defense processes - lymphocytes, mast cells, eosinophils or neutrophils

Impact of corporate governance on bank profitability - post reforms by RBI and SEBI
Get PDFIn India, the increasing awareness with respect to CG, particularly in the commercial banking industry can be attached to a variety of factors such as liberalization, scams, corporate failures in banks, accounting and other irregularities that have led to an era of rising public distrust of the governance process in the banking landscape. Because of economic problems arising out of banking mis-management and failures, studies on bank profitability have become imperative for recognizing problems and mitigating economic risks. Over the last few years, Indian banks' toxic loan pile has increased considerably in addition to frequent instances of governance lapses being identified by the regulator. Indian banks' failure to adhere to acceptable business practices has unraveled a chain of events that have caused distress to the public causing the regulator to overhaul its outlook towards CG in banks and decision to infuse capital in the banking sector to revive it. The study attempts to assess the relation between governance and other factors' impact on the bank profitability with empirical evidence from Axis, HDFC, ICICI, PNB, SBI and Yes Bank. The study outlines links between the Bank's Size, Board Independence, Independence of Audit Committee, Audit Committee Strength, Duality of Role, NPA Divergence and profit by using Return on Equity, Return on Assets and Net Interest Margin as proxies for measuring profitability. The findings indicate that Audit Committee Independence, Audit Committee Strength had a statistically significant impact on bank profits, while Bank Size had a negative affiliation to profits as per all three indicators of profits
Health care logistics: mapping and optimization of patients logistics
Get PDFHealthcare logistics play an important role in management, being attributed the activities of acquisition, distribution and movement of materials, professionals and patients. This work aims to develop a study, using the healthcare logistics in the movement of patients in the third health region of Paraná, proposing a linear programming problem that will pass through a computational simulation, considering the existing demands and constraints in the system, aiming to optimize the flow of patients from this region. The present study developed four mathematical models, based on demands and constraints followed by linear programming in order to find the best possible solution for the flow of patients from the third health region of the state of Paraná. The study developed reached its goal of optimization, generating an economy in the transportation of patients. Through the analysis of the results, it is concluded that the model that best suits the presented problem is the one of costs minimization, since the one of vehicles presented higher costs. Possibly the model that minimizes the vehicles would bring better results if the vehicles were not outsourced, but of the Ponta Grossa City Hall (PMPG). Was possible to verify the importance of the theme, especially when referring to the flow of patients in the health services due to the lack of studies with this specific approach. Even with the scarcity of data, it is possible to notice the potential for improvements on this patient transport system

Positional modeling of the 2T6R robot mechanism
Get PDFThe positional modeling of the 2T6R robot mechanism is done for inverse kinematics, i.e. when the imposed positions of the end effector T, imposed, belonging to the final element 3, are known and the necessary positions and speeds of the two input motors, the two leading elements, are determined, 1 and 6. It is proposed to solve a simple algorithm in the program MathCad 2000, which uses for initiation the logical function If Log. The kinematic output parameters, i.e. the parameters of the foot and practically of the final effector, i.e. those of the point marked with T, will be determined for initiating the working algorithm using the logical functions, "If log (ical)", with the observation that here plays the role of parameters input; is positioned as already specified in reverse kinematics when the output is considered as input and input as output. The logical functions used, as well as the entire calculation program used, were written in Math Cad 2000
