Background and objective: Urological diseases represent a signifi cant health issue worldwide. Presented study aimed at assessing current urological knowledge and confi dence in performing urological diagnostic and therapeutic procedures among medical students at Jagiellonian University Medical College in Poland and compare it on diff erent stages of the undergraduate medical education. Material and methods: We designed an anonymous survey distributed among Polish students from 1st to 6th year of medical studies, before and aft er clinical urology course. Questions concerned general urological knowledge, prostate diseases, erectile dysfunction, and self-reported practical urological skills. Results: Overall, 437 respondents participated in the survey. Mean total test score in our study groupwas 50.08%, mean general urological knowledge score was 53.44%, mean prostate diseases knowledge score was 55.43%, mean erectile dysfunction score was 36% and mean practical skills score was 45.83%. Mean total test score increased with consecutive years of studies (R = 0.58; p <0.001). Th e risk of an above average total test score was signifi cantly infl uenced by the urology course (OR = 7.95, 95%CI = 1.81–34.84, p = 0.006) and the year of medical studies (4th–6th vs. 1st–3rd) (OR = 5.16, 95%CI = 3.41–7.81, p <0.001). Practical skills score above average was signifi cantly more frequent in the group aft er the urology course (OR = 6.75, 95%CI = 1.54–29.58, p = 0.011). Conclusions: Results of this study reveal low mean scores obtained by students, even aft er completing the urology course, which implies that curriculum requires further development. Urological knowledge and self-assessed practical skills increased with years of medical education. The urology course improved the score obtained in our survey, both in terms of total test score and practical skills.

Introduction: Interventional cardiology (IC) is a rapidly expanding fi eld of medicine. Medical studies should provide students the necessary level of knowledge about new techniques in IC. The aim of the study was to assess the medical students’ knowledge about various new areas of IC. Material and methods: Self-designed questionnaire was used to assess student’s knowledge. It contained 31 questions. Th e initial 3 questions concerned general information, the remaining ones were related to diff erent IC techniques: Transcatheter Aortic Valve Implantation (TAVI), Bioresorbable Vascular Scaff old (BVS), percutaneous mitral regurgitation repair methods, Left Atrial Appendage Occlusion (LAAO), Renal DeNervation (RDN), Balloon Aortic Valvuloplasty (BAV) and Atrial Septal Defect/Persistent Foramen Ovale (ASD/PFO). One point for each correct answer was awarded. Results: In our study participated 104 students. Mean score was 15.9 ± 5.8 points. 24% of participants were 3rd year students, 38% — 4th, 20% — 5th and 18% — 6th. Th ere was no diff erences in level of knowledge between students of diff erent years of studies (p = 0.2). Students from Students Research Groups (SRG) achieved higher score in comparison with students no attending SRG (19.3 ± 6.3 vs 13.3 ± 3.7; p <0.001) as well as students interested in cardiology comparison with other (19.6 ± 5.9 vs 13.0 ± 3.8; p <0.001). Students from SRG and interested in cardiology reached also higher results in practically every area of IC in comparison with other. Conclusions: Participants have insuffi cient, outdated and incomplete knowledge of new methods in IC. Th ere was no signifi cant diff erence in students of diff erent years of studies. Students belonging to cardiological SRG and interested in cardiology have greater knowledge in IC.

This article analyzes the technology of creating and updating a digital topographic map using the method of mapping (generalization) on an updated map with a scale of 1 : 25;000 based on the source cartographic material. The main issue in the creation of digital maps is the study of map production accuracy and error analysis arising from the process of map production. When determining the quality of a digital map, the completeness and accuracy of object and terrain mapping are evaluated. The correctness of object identification, the logical consistency of the structure, the and representation of objects are assessed. The main and the most effective method, allowing to take into account displacement errors for the relief during image processing, is orthotransformation, but the fragment used to update the digital topographic map needs additional verification of its compliance with the scale requirements of the map. Instrumental survey will help to clearly identify areas of space image closer to nadir points and to reject poor quality material. The software used for building geodetic control network should provide stable results of accuracy regardless on the scale of mapping, the physical and geographical conditions of the work area or the conditions of aerial photography.

The paper presents the results of research on the possibilities of fixing ship position coordinates based on results of surveying bearings on navigational marks with the use of the CCD camera. Accuracy of the determination of ship position coordinates, expressed in terms of the mean error, was assumed to be the basic criterion of this estimation. The first part of the paper describes the method of the determination of the resolution and the mean error of the angle measurement, taken with a camera, and also the method of the determination of the mean error of position coordinates when two or more bearings were measured. There have been defined three software applications assigned for the development of navigational sea charts with accuracy areas mapped on. The second part contains the results of studying accuracy in fixing ship position coordinates, carried out in the Gulf of Gdansk, with the use of bearings taken obtained with the Rolleiflex and Sony cameras. The results are presented in a form of diagrams of the mean error of angle measurement, also in the form of navigational charts with accuracy fields mapped on. In the final part, basing on results obtained, the applicability of CCD cameras in automation of coastal navigation performance process is discussed.
