The Design of a Patient Transportation Robot's Lifting Arms Considering Comfort and Safety without the Presence of a Sheet

A transportation robot's lifting arms have an effect on the comfort and safety of patients. Improved arms have been designed through dynamic and static analyses to increase safety if a sheet not present on the lifting arms. To design the lifting arms, experimentation is very helpful, however, it is difficult and dangerous to experiment on patients; therefore, a simple human model was made and used for the dynamic analysis. Through the dynamic analysis results, a safe width and comfortable location for the lifting arms were determined. The thickness was then determined by static analysis and optimum design. In addition, tests have been conducted to confirm comfort and safety by deploying the designed lifting arms onto a transportation robot

Primary Graft Dysfunction after Heart Transplantation

The entire transplant journey that the donor heart experiences affect the donor heart function early after transplantation. The early graft dysfunction without discernible cause is primary graft dysfunction (PGD) and has been one of the critical complications and the cause of early mortality after orthotopic heart transplantation. Although, numerous researchers investigated the pathophysiology and the related biomarkers, the process is multifactorial and therefore no definite biomarker has been proposed. After the recent definition from the International Society of Heart and Lung Transplantation, the standard of management is still under investigation by each status. Here, the prevalence, pathophysiology, biomarkers, and recent progression of management of PGD will be reviewed

Accounting Conservatism, Changes In Real Investment, And Analysts Earnings Forecasts

This study examines whether sell-side analysts fully incorporate into their earnings forecasts the joint effects between accounting conservatism and changes in real investment on the quality of current earnings. Our results indicate that sell-side analysts do not fully incorporate such effects when they forecast future earnings so that they overestimate (underestimate) future earnings when current earnings are inflated (depressed) by those effects. Thus, we conclude that sell-side analysts do not recognize fully the joint effects between accounting conservatism and real activity on the earnings quality and that they need to mitigate their bias to enhance market efficiency by providing investors with a good benchmark for their earnings expectation
