Randomized controlled trial : comparison of visual fatigue levels and test scores between computer-based and paper-based examinations of DLSHSI senior medical interns in Dasmarinas, Cavite, S.Y. 2015-2016

The researchers employed a randomized controlled trial study design. All senior medical interns who graduated from DLSHSI were the sample population. They were selected using purposive sampling. Random allocation was done. No form of blinding was applied due to the nature of interventions. One group took computer-based examinations (CBE) while the other group took paper-based examinations (PBE) with the same content and format. Subjects were asked to answer the Visual Discomfort Scale questionnaire to assess visual fatigue level. Data was analysed using chi-square and Analysis of Variance (ANOVA). Students in the CBE group had significantly higher Visual Fatigue Level. On the other hand, there was no statistically significant difference in test scores of the two comparison groups. Visual fatigue had no significant relationship with gender and visual health status as risk factors

Antimicrobial properties of ethanolic crude extract of mangosteen pericarp (garcinia mangostana) against gram-positive bacteria (staphylococcus aureus and streptococcus pyogenes) and gram-negative bacteria (escherichia coli and salmonella enterica serovar typhi)

This study aimed to determine the antimicrobial properties of mangosteen (Garcinia mangostana L.) ethanolic crude extract against gram positive (Staphylococcus aureus and Streptococcus pyogenes) and gram negative bacteria (Escherichia coli and Salmonella enterica serovar typhi). An analytic-experimental study wherein the research design used was randomized control trial (RCT). This was to assess the antimicrobial effect of Garcinia mangostana on gram-positive (Escherichia coli and Salmonella enterica serovar typhi). The effect of the different concentrations of the mangosteen pericarp crude extract had been determined through measurement of the zone inhibition and determination of the minimum inhibitory concentration. Mangosteen pericarp ethanolic crude extract inhibitory and bactericidal effects on gram positive species with a minimum inhibitory and bactericidal concentration of 1500 microgram/mL, on the other hand, it was not inhibitory or bactericidal against the gram-negative representative species
