Prediction regions based on dissimilarity functions.

This paper presents a new methodology to obtain prediction regions of the output of a dynamical system. The proposed approach uses stored past outputs of the system and it is entirely data-based. Only two hyperparameters are necessary to apply the proposed methodology. These scalars are chosen so that the size of the obtained regions is minimized while fulfilling the desired empirical probability in a validation set. In this paper, methods to optimally estimate both hyperparameters are provided. The provided prediction regions are convex and checking if a given point belongs to a computed prediction region amounts to solving a convex optimization problem. Also, approximation methods to build ellipsoidal prediction regions are provided. These approximations are useful when explicit descriptions of the regions are necessary. Finally, some numerical examples and comparisons for the case of a non-linear uncertain kite system are provided to prove the effectiveness of the proposed methodology.

[Undergraduate teaching of internal medicine in a private hospital]. / Docencia de pregrado en medicina interna en un hospital privado: diez años de experiencia.

There is a 10 years teaching experience for fourth year medical students and interns in a Chilean private hospital. The students attend an eight weeks practical course. The interns rotate during 16 weeks by specialties and make shifts. The hospital structure with Clinical Services and Medical-Surgical departments facilitates the teaching process. There are approximately 30,000 admissions per year with a mean stay of 3.7 days, that allow the students to be in touch with patients with different diseases that are managed with updated technology. We emphasize the ethical and clinical management of concrete problems of patients, learning and communication skills. The students evaluate their stay answering surveys and with semi structured interviews. Teaching is assessed by tutors and heads of departments, in clinical rounds, sometimes prepared by the students, by a thorough revision of problem oriented medical records and with practical and theoretical tests. The results of the program have been quite satisfactory for participants.
