Applied Physics

A.Y. 2020/2021
Overall hours
Learning objectives
The module has the aim of deepening clinical aspects of the doctor-patient relationship in some situations of relational engagement. Issues related to conflict of interest, euthanasia-assisted suicide and end-of-life decision, patient and physician emotionality and the use of the relational model based on empathy will be addressed. Moreover, problems related to he informed consent-access to ethics committees and the causes of legal medical litigation will be considered (frontal lessons).
Expected learning outcomes
Being able to frame a problem, to analyze it by identifying the essential aspects and rationalizing their connections. Know how to apply the most appropriate model to solve it.
Course syllabus and organization

Single session

Lectures will still take place in classrooms, if students can't reach the buildings we might consider alternative ways.

Prerequisites for admission
Lines A-L e M-Z:
Admitted students pass an entrance test that covers the preliminary knowledge required by the course.
Teaching methods
Lines A-L e M-Z:
The teaching is organized in formal lessons and classroom exercises. The classroom exercises include individual and group work under the guidance of the teacher.
Teaching Resources
Lines A-L e M-Z:
Scannicchio. Fisica Biomedica. EDISES
Halliday Resnick Walker. Fondamenti di Fisica. CEA
Borsa Lascialfari. Principi di Fisica. EDISES
Assessment methods and Criteria
Lines A-L e M-Z:
The learning test includes a written test for admission to an oral test.
The written test includes exercises on topics presented during the formal lessons and classroom exercises. Answers will be expected in the form of multiple choice or open. Each question has a score. The overall score of the written test leads to the admission to the oral test and its validity is restrained to the paired oral test. The use of a pocket calculator is allowed. The use of other means is restricted to the existing rules for special cases and agreed in advances. The positively graded written tests will be listed together with the call for oral tests on the Ariel website.
The final grade is the result of the oral test.
