Abstract
The Grade Point Average (GPA) as a measure of student performance in implementing the curriculum is expected to be correlated with the UKMPPD results to produce competent doctors with national standards. However, this is not in line with some who do not pass the UKMPPD at the Faculty of Medicine, University of Palangka Raya. This problem raises the question, can a medical student’s GPA ensure a fresh graduate doctor’s competency to pass UKMPPD? The research design was descriptive-analytic, with a cross-sectional design consisting of 132 students participating in UKMPPD as the first participants from May 2016 to November 2019. The data obtained were the results of preclinical and clinical GPA and UKMPPD. Data analysis using Pearson correlation test and Mann Whitney test. Statistical analysis showed that there was a significant relationship (p <0.001) between the preclinic GPA and the results of CBT (r = 0.642), OSCE (r = 0.329), and UKMPPD. Clinic GPA showed significant correlation (p <0.001) with CBT (r = 0.429), and UKMPD results (p = 0.001), but had no significant correlation (p = 0.167) with OSCE. These results indicate that the GPA of Preclinic and Clinic scores can be used as an indicator of learning outcomes to determine cognitive test results.

Published: February 2021

Abstract
In firefighting situations, firefighters will encounter multiple flame exposures during go through the fireground several times. In this study, the effects of multiple flame exposures on thermal shrinkage and thermal protective performance of three fabrics used in firefighting clothing were investigated. The fabric surface morphology after flame exposure was obtained by a handy scanner, and further processed in ArcGis software. The thermal shrinkage of fabrics was characterized by ten shrinkage parameters and then quantified by using principal component analysis. The results showed that flame exposure frequency had influence on the thermal shrinkage of fabrics. As compared to several short-duration exposures, a long-duration continuous exposure resulted greater thermal shrinkage. The correlation analysis showed that there was no significant correlation between thermal shrinkage of the fabric and its thermal protective performance. The findings in this study indicated that the effects of multiple flame exposures on thermal shrinkage and thermal protective performance of firefighters clothing should be considered during clothing design and performance prediction.

Abstract
Functional flexible membranes with superior water repellency and moisture permeability, which prevent water penetration and allow rapid passage of water vapor, offer new possibilities for a wide range of applications in various fields. A new type of functional nano-fiber membrane can be prepared by a facile electrospinning method, thermal post-treatment and chemical crosslinking, which can provide excellent mechanical properties. In this study, low melting point polyvinyl-butyral (PVB) elastomers were incorporated into polyvinylidene fluoride (PVDF) to change the adhesion between the membrane bonding network structure and the fibers to impart durable and strong mechanical properties to the membrane. The effects of PVDF/PVB concentration on the waterproof and breathable properties were investigated by systematically tabulating the morphology, contact angle, water vapor transmission rate (WVTR), and fracture length of PVDF/PVB. The results showed that the prepared nanofiber membrane could maintain high hydrostatic pressure (85.15 kPa) and high water vapor transmission rate (10.28 kg m-2d-1), and at the same time, the membrane exhibited excellent tensile stress (13.07 MPa), indicating its wide application in separation process and protective clothing.
