The Impact

Abstract In medical education and preclinical, clinical and transdisciplinary studies, tutors should be able to perform and offer qualitative study courses with more articulated perspective on higher educational sustainable development in higher education. Digital images have found their direct way to education in different medical areas. The aims of the study are to assess and verify the impact of cross-sectional images on the study process of Human Anatomy. In 2018, two randomly selected groups of 200 students from 2nd study year, Faculty of Medicine (Rīga Stradiņš University) were asked by tutors to identify several anatomical structures, using a three-dimensional virtual dissection table “Anatomage”. Group I analyzed cross-sectional images after cutting and segmentation of human body with interactive tools. Group II studied X-ray pictures, computerized tomography scans and magnetic resonance images of different regions and systems. The present paper focuses on the rate of cross-sectional image effectiveness in both groups. Analyzed detailed images represent their role in teaching and learning of Human Anatomy. Interpretation of these medical images will require very deep anatomical knowledge from basic studies until clinical courses.

There are various combinations of 3D printing technology and medical study process. The aim of this study was to summarize our first experience on 3D printing and outline how 3D printed models can be successfully used in Human Anatomy modern teaching and learning. In 2018 autumn semester, together with traditional methods, a three-dimensional (3D) printing has been introduced into Human Anatomy curriculum at Department of Morphology. In practical classes 39 groups of students from Faculty of Medicine 1st year together with 3 tutors used 3 different open source softwares to create anatomical models and prepared them for printing process. All anatomical models were produced using an FDM 3D printer, a Prusa i3 MK2 (Prusa Research). As methods for data collection were used our observational notes during teaching and learning, analysis of discussions between tutors and students, comments on the preparing and usability of the created and printed models. 3D printing technology offered students a powerful tool for their teaching, learning and creativity, provided possibility to show human body structures or variations. Presented data offered valuable information about current situation and these results were suitable for the further development of the Human Anatomy study course.

Virtual Dissection

INTRODUCTION An increasing number of digital technologies have been introduced which assist in some practical aspects of the teaching and learning of Human Anatomy. For modern-day students, more and more cross-sectional images of the human body are available as materials in their studies. Digital 2D images and/or 3D images such as high-resolution computed tomography (CT) scans and magnetic resonance (MR) have been received with much enthusiasm and have found their way into anatomy courses and practical classes. An emphasis on sectional anatomy can help medical students develop and improve their knowledge of cross‐sectional imaging. The aim of this study was to assess and verify the impact of cross-sectional images on the study of Human Anatomy. MATERIALS AND METHODS 200 medical students in their 2nd study year at Rīga Stradiņš University were included in this investigation in 2018. In practical classes, all students were asked by tutors to identify several anatomical structures using "Anatomage", a 3D virtual dissection table (USA). They were randomly divided into two groups: Group I analysed cross-sectional images of the human body after cutting and segmentation with interactive tools; Group II studied X-rays, CT scans and MRI images of different regions and systems. Similar images in all possible cross-sectional planes were displayed. The pathological findings from the cross-sectional images were used to develop several clinical questions and cases. At the beginning of each practical class, the tutor spent about 30 minutes demonstrating the themes in the images to all the students. At the end of the teaching session, their understanding of the relationships between anatomical structures and the rate of cross-sectional image effectiveness among both groups was assessed by means of discussion. RESULTS By this time, students were able to identify the position of bones and organs from the lectures, practical classes and dissections. The majority of students recognized the landmarks, anatomical structures and relationships between them on cross-sectional images in three planes. By removing different kinds of tissue, students in both groups were able to learn more difficult anatomical topics and to explain details in these complicated regions. Self-assessment exercises helped students verify their understanding of topographical relations and regional anatomy. In these groups, students with less prior anatomy experience wanted to focus more on the basics of anatomy whereas students with more prior anatomy experience wanted to see and study more complex and interactive materials in cross-sectional images. CONCLUSION This study demonstrated the role of the 3D virtual dissection table "Anatomage" in facilitating students' ability to interpret cross-sectional images and understand the relationships between different anatomical structures. All the X-rays, CT scans and MRI cross-sectional images used played an important role in the teaching and learning of Human Anatomy. Skills and the ability to interpret these medical images is important for the application of anatomical knowledge right from basic studies until clinical courses.

The Impact

Water entry of a hull with wedge-shaped cross sections is analyzed. The stiffened platings between two transverse girders on each side of the keel are separately modeled. Orthotropic plate theory is used. The effect of structural vibrations on the fluid flow is incorporated by solving the two-dimensional Laplace equation in the cross-sectional fluid domain by a generalized Wagner's theory. The coupling with the plate theory provides three-dimensional flow effects. The theory is validated by comparison with full-scale experiments and drop tests. The importance of global ship accelerations is pointed out. Hydrodynamic and structural error sources are discussed. Systematic studies on the importance of hydroelasticity as a function of deadrise angle and impact velocity are presented. This can be related to the ratio between the wetting time of the structure and the greatest wet natural period of the stiffened plating. This ratio is proportional to the deadrise angle and inversely proportional to the impact velocity. A small ratio-means that hydroelasticity is important and a large ratio means that hydroelasticity is not important.

✓ Data from single 10-minute magnetic resonance scans were used to create three-dimensional (3-D) views of the surfaces of the brain and skin of 12 patients. In each case, these views were used to make a preoperative assessment of the relationship of lesions to brain surface structures associated with movement, sensation, hearing, and speech. Interactive software was written so that the user could “slice” through the 3-D computer model and inspect cross-sectional images at any level. A surgery simulation program was written so that surgeons were able to “rehearse” craniotomies on 3-D computer models before performing the actual operations. In each case, the qualitative accuracy of the 3-D views was confirmed by intraoperative inspection of the brain surface and by intraoperative electrophysiological mapping, when available.

ABSTRACT Introduction To evaluate the role of endometrial thickness and volume using three-dimensional transvaginal ultrasound (3-D TVUS) in order to predict pregnancy outcome in assisted reproductive technology (ART) cycle on the day of human chorionic gonadotropin (hCG) administration. Materials and methods In this prospective study, the long protocol of controlled ovarian hyperstimulation was prescribed for women. Endometrial thickness and volume were measured using the 3-D TVUS, for 166 women undergoing ART cycle, on the day of hCG administration at Royan Institute, Tehran, Iran, between 2009 and 2011. All patients were divided into three groups. Regarding endometrial thickness, there are three groups as follows: Group I: . 7 mm, group II: 7.14 mm, and group III: > 14 mm; all patients were also divided into three groups according to endometrial volume calculated as follows: Group IV: < 2 cc, group V: 2.4.5 cc, group VI: > 4.5 cc. Pregnancy rate (PR) was compared between all groups. Results A total of 166 patients were analyzed. Overall PR was 39.8% after in vitro fertilization (IVF). Participant's age ranged from 20 to 38 years old with the mean age of 29.9 ± 4.23. No significant cut-off value was found for endometrial thickness and volume. Conclusion Endometrial thickness and volume on the day of hCG are significant in limited value and in a clinical setting for predicting implantation in ART cycle.

The Impact

Background: The outbreak of the deadly disease COVID-19 has shaken the entire world. The pandemic has resulted in a global lockdown affecting all areas of life, including medical education. This has impeded the traditional way of teaching and learning activities and forced educational institutions such as medical universities to shift rapidly to distance and online learning. Aims and Objectives: The aim was to find out the impact of COVID-19 and the perception of undergraduate students of B.P. Koirala Institute of Health Sciences (BPKIHS) of learning dermatology through online means. Methods: A cross-sectional study was conducted with a self-administered online questionnaire. The inclusion criteria were all MBBS third and fourth years students of BPKIHS willing to participate in the study. Result: A total of 151 participants agreed to complete the online survey questionnaire. The overall attitude toward online education was positive. The majority of students agreed that online learning material should be of high quality for online education (66.2%) and that online learning will bring new opportunities for organizing teaching and learning (62.3%). Zoom and Dudal were the most common online tools used by students. The geographic location, lack of past experience in using online tools, and communication barriers such as a poor Internet connection and frequent electricity cutoffs were identified by students as the main barriers to online education. Conclusion: Although the COVID-19 pandemic culminated in the lockdown of medical universities, it provided opportunities for bringing innovations into effect. Such large-scale studies are missing in developing countries such as Nepal, thus further research is needed to explore these possibilities nationwide.
