Purpose: The aim of this study was to compare the effect of different simulation modalities on knowledge, skill, stress, satisfaction, and self-confidence levels of students receiving undergraduate education in three nursing schools. Method: This was an experimental study. Students applied the scenario of “Respiratory Sounds Assessment” which was prepared according to three different simulation modalities. In the study, the standardized patient, high-fidelity simulation, and partial task trainer were used as simulation modalities. Results: An increase was observed in postpractice knowledge levels of the three groups which had similar knowledge levels before the practice. Virtual Analog Scale stress levels of the students in the standardized patient group were higher than those of others. The students’ mean scores of satisfaction in learning were higher in the standardized patient group. The students in the partial task trainer group had lower scores of self-confidence in learning. Skill scores of the students were lower in the standardized patient practice than those in others. Conclusion: Simulation-based experiences give students the opportunity of experiencing situations they may experience in the actual practice beforehand. Therefore, this may increase their performance in real practices, as reality increases in the standardized patient group.
Different MAP Conditions to Improve the Shelf Life of Sea Bass
Hülya Turan,Demet Kocatepe 한국식품과학회 2013 Food Science and Biotechnology Vol.22 No.6
Shelf life of cultured sea bass packaged in air,vacuum, and gas mixture packages stored for 40 days at2.90±0.02oC was compared. The gas mixtures used containedCO2, O2, and N2 at difference percentages (M1: 75% CO2/25% N2; M2: 60% CO2/40% N2; M3: 30% O2/30% CO2/40% N2). Sensory and physical parameters, chemicalchanges, and microbiological counts were monitoredduring storage. Storage with a gas mix including 75 and60% CO2 was more effective than vacuum processing andpackaging with a gas mix that included oxygen. Vacuumwas the most effective method for preventing lipidoxidation. The optimum method for sea bass in view of allanalysis results was modified atmosphere packaging(MAP) and the most suitable gas mix ratio was 75% CO2/25% N2. The best days for consumption of sea basspackaged with air, MAP (M1, M2, and M3), and vacuumwere 4th, 28th, 28th, 16th, and 20th days, respectively.
