Background: Anatomy is a crucial part of medical education, and there have been attempts to improve this field by utilizing various methods. With the advancement of technology, three-dimensional (3D) materials have gained popularity and become a matter of debate about their effectiveness compared to two-dimensional (2D) sources. This research aims to analyze the effectiveness of 3D PDFs compared to 2D atlases., Methods: This study is a randomized controlled trial involving 87 Year-1 and Year-2 medical students at Gazi University Faculty of Medicine, Turkey. The study was conducted in two steps. In Step-1, students were randomized to watch lecture videos on liver anatomy and male genitalia anatomy supplemented with either a 3D PDF (intervention group) or 2D atlas (control group) images. Following the video lectures, a test (immediate test) was administered. In Step-2, the same test (delayed test) was administered 10 days after the immediate test. The test scores were compared between the intervention and control groups. In addition to the descriptive analyses, Chi-square and Mann-Whitney U tests were performed., Results: In the immediate test, while there was no significant difference between the groups for the liver test (p > 0.05), 3D PDF group's scores (Median = 24.50) was significantly higher than the 2D atlas group's in the genitalia test (Median = 21.00), (p = 0.017). The effect size (Cohen's d) was 0.57. In the delayed test, there was no significant difference between the groups in the liver and genitalia tests (p > 0.05). However, the effect size in the immediate genitalia test was 0.40. Year-1 students' immediate test of genitalia performances were significantly higher in the 3D PDF group (Median = 24.00) than the 2D atlas group (Median = 19.00), (p = 0.016). The effect size was 0.76. Also, Year-1 students' 3D PDF group (Median = 20.50) presented with significantly higher performance than the 2D atlas group (Median = 12.00), (p = 0.044) in the delayed test of genitalia, with the 0.63 effect size., Conclusion: 3D PDF is more effective than 2D atlases in teaching anatomy, especially to initial learners. It is particularly useful for teaching complex anatomical structures, such as male genitalia, compared to the liver. Hence, it may be a valuable tool for medical teachers to utilize during lectures., (© 2023. The Author(s).)

Background: This study was conducted to determine the effect of yoga practice on fear of childbirth and childbirth self-efficacy., Materials and Methods: This study was performed in a quasi-experimental model with pretest and post-test control groups. The participants of the study were women who applied to a pregnancy education class at a hospital. Ninety women participated in the study. The data used in the study were collected using the Individual Information Form, the Wijma Delivery Expectation/Experience Scale (Version A), and the Childbirth Self-Efficacy Scale., Results: After participating in yoga practice, the pregnant women in the experimental group exhibited decreased fear of childbirth and increased childbirth self-efficacy (p < .05). On the other hand, the pregnant women in the control group displayed increased fear of childbirth and decreased childbirth self-efficacy (p < .05)., Conclusion: Based on the results of this study, yoga practice reduces fear of childbirth and significantly increases childbirth self-efficacy., (Copyright © 2021.
