Learning objectives
The course of Physics has been designed to convey knowledge and understanding of basic physics principles and their application in practice. The topics are geared to concrete analysis and research problems.
The course will provide the necessary tools to address issues of increasing complexity preparatory to other major disciplines of the degree course, such as Chemistry, Biology,
Physiology, Biochemistry, etc.. , which are based on physical phenomenology.
The course will also provide the conceptual basis for understanding a number of major technologies that with increasing frequency are used in medicine, such as: centrifuges, endoscopes, microscopes, transducers for ultrasound equipment, laser systems, radiology equipment and NMR, radiation detectors, etc. In this sense, the module also aims to develop the students' attitude towards independent study and continuing education on the application of physical techniques to diagnosis and therapy in medicine.
As its final, but perhaps most important, goal, the course has been designed to stimulate students to become more familiar with certain common concepts, that are not always sufficiently explained in previous study, such as: mechanical action between bodies in contact, exertion
and energy in action, dynamic aspects resulting from elastic force and impact, friction and thermal and thermodynamic aspects, static and dynamic properties of gaseous and liquid fluids, light and its manifestations, including in relation to the structure of the eye and its physical defects, fundamentals of electrical, magnetic and nuclear phenomena, the laws that govern potential and current, electromagnetic and nuclear radiation, detection and control.
IT module provides students with knowledge, theory, basic computer technologies
available today.
At the end of the course the student should be able to know the basic
characteristics of the computer, the network's potential with regard to
the sharing of resources and data access , software for writing and data
entry , accessing and updating of data on the database, filling out forms,
etc..
Describe the possible applications of PCs in medicine with regard to the
acquisition and analysis of signals and images, the management of the
department, the clinical decision support and teaching.
Use the basic tools of surfing the net to find the sources nursing
Critically analyze the sources nursing according to the criteria of
evidence based nursing.
The module of Medical Statistics is designed to introduce the student to
the basics of statistical thinking and its application in practice. The topics
are geared to concrete problems of analysis and research and deal in
particular with situations and cases drawn from the medical literature.
Starting from the multitude of information from which we are faced daily,
the course aims to give students the statistical tools needed to describe
and analyze the data, extract useful information and make informed
decisions. Special emphasis will be put on statistical reasoning,
interpretation and decision-making process. We will insist more on the
conceptual understanding that the mechanical calculation, especially in
light of the wide range of software available for analysis. The theory will
be made explicit by means of practical exercises and teaching cases,
therefore, the ultimate goal of the course is that the student learn "how
to do" as well as knowing.

Teaching methods
During the lectures, the topics contained in the program will be illustrated and commented.
At the end of each topic classroom exercises explaining the application of the theory in practice will follow. The formal procedure and the step by
step execution of the necessary calculations will be described. Both manual solution and computer calculation will be shown.
The course will be held through lectures to Students either in the classroom (“in presenza”) or in synchronous-streaming (“in telepresenza”) on the Teams platform. Therefore, the opportunity of Student/Teacher interaction will be preserved both face to face and remotely, by the simultaneous use of the Teams platform.
Lectures will be supported by slide presentations, which will be available to students on the Elly platform (https://elly.medicina.unipr.it).
Assessment methods and criteria
Written examination on the topics covered during the classroom lectures.
In case of the persistence of the health emergency, the exams will be conducted remotely, as follows:
structured written test conducted remotely (by Teams and Elly). The candidate will remain connected with microphone and video camera turned on and will carry out the test under the control of the commission.
The final mark, reported directly on Esse3, will correspond to the arithmetic average of the assessments obtained in the written test.
