The authors propose a pedagogical and technological paradigm for e-textbooks in medical education using open source software with minimal IT skills required. Technologies used to develop e-textbooks are connected with: publication and distribution of e-textbooks, e-book readers, and editing tools. The paper also discusses a survey that targeted students of medical sciences, which focused on their understanding of their educational needs that can be met through new online resources as well as their expectations of how such e-textbooks should be like.

As a continuous process, assessment takes time, and therefore, where possible, it is replaced by e-assessment. In medical sciences, theoretical knowledge is often assessed using electronic tests based on multiple choice questions. However, the method of preparation to this type of exams and the mere filling of the test form may be problematic for students. Given the above, the authors have decided to monitor the students' approach to the online tests in order to eliminate or correct any arising problems. This document presents the results of surveys taken in the academic years 2014/15 and 2015/16. In addition, the article shows the role of formative and summative evaluation in eassessment as well as the need to apply standards for the development of assessment tools and systems. Even with many advantages, the e-assessment ...

With the development of programming technologies, the range of interactive elements, such as games, simulations, and decision-making labyrinths that match the characteristics of the knowledge they present has significantly expanded. The article presents a review of the available technologies based on their use in creation of interactive content for distance education. The authors also present the applications of selected interactive elements in different educational contexts.

Creation of a self-learning environment supported with self-tests is received well, or even enthusiastically, among students. On the other hand, there is a relatively large group of opponents among university teachers, who do not see the need for changes in teaching and testing methodology to be made. This attitude may be surfacing as a result of anxiety connected with implementing new technologies in teaching medical subjects, as well as the belief that implementing new technologies does not have an immediate effect on learning quality. The authors of this article attempt to demonstrate that a thoughtful choice of e-learning platform facilitates the process of implementing online learning and testing aids in medical faculties. The second part of the article presents initial results of studies concerning the efficiency of learning enhanced with self-tests. Our analysis details the resul...

The portal application must meet a number of capacity and functionality requirements. Learning goals are pursued through implementation of appropriate tools available in the portal. In the article that follows, the authors attempt to analyze this aspect of medical education as utilized by blended learning and e-learning classes. The article presents a proposal for a set of tools to organize classes in an e-learning portal at a medical school. In addition, the article presents the opinions of students of the Poznan University of Medical Sciences and the Medical University of Bialystok who took part in distance education classes.

Para ello, se recogieron espectros de fluorescencia sincrónica en el rango de 240-700 nm con intervalos de longitud de onda de 10, 30, 60 y 80 nm. Las proyecciones algorítmicas sucesivas (SPA) se aplicaron para la determinación de las longitudes de onda representativas mientras que el método de análisis discriminante lineal (LDA) se empleó para clasificar los aceites de oliva. Se obtuvo un error de clasificación del método bajo (0,9-6,4%) para las medidas recogidas en todos los intervalos de onda. La mejor precisión de clasificación se obtuvo para intensidades de fluorescencia sincrónica adquiridos a 10 longitudes de onda seleccionadas con intervalos de longitud de onda de 10 nm.

This means that approximative compactness coincides with the drop property defined by Rolewicz in Studia Math. 85 (1987), 25-35. Using this general result we find criteria for approximative compactness in the class of Musielak-Orlicz function and sequence spaces for both (the Luxemburg norm and the Amemiya norm) as well as critria for this property in the class of Lorentz-Orlicz spaces. Criteria for full rotundity of Musielak-Orlicz spaces are also presented in the case of the Luxemburg norm. An example of a reflexive strictly convex Köthe function space which is not approximatively compact and some remark concerning the compact faces property for Musielak-Orlicz spaces are given.

Considering the importance of monitoring adulterations of genuine cheeses, the potential of fluorescence spectroscopy for the detection of cheese adulteration with plant oils was investigated. Synchronous fluorescence spectra were collected within the range of 240 to 700 nm with different wavelength intervals. The lowest detection limits of adulteration, 3.0 and 4.4%, respectively, were observed for the application of wavelength intervals of 60 and 80 nm. Multiple linear regression models were used to calculate the level of adulteration, with the lowest root mean square error of prediction and root mean square error of cross validation equalling 1.5 and 1.8%, respectively, for the measurement acquired at the wavelength interval of 60 nm. Lower classification errors were obtained for the successive projections algorithm-linear discriminant analysis (SPA-LDA) rather than for the principal component analysis (PCA)-LDA method. The lowest classification error rates equalled 3.8% (Δλ=10 and 30 nm) and 0.0% (Δλ=60 nm) for the PCA-LDA and SPA-LDA classification methods, respectively. The applied technique is useful for detecting the addition of plant fat to hard cheese.

The volatility of materials and the continuous evolution of tools and distance teaching and learning portals must involve a continuous improvement of ICT competences among people involved in teaching with this method. This article discusses selected aspects of preparing and teaching classes and evaluating students' knowledge in teaching with the use of the blended learning method, with a special consideration of ICT competences necessary in this respect. Moreover, the authors present certain issues which are frequently less known to academic teachers but would significantly facilitate and streamline their work, such as: virtual seminars, leading project groups, distributing information via a portal, organisational consultation tools, etc.

With the use of the presented tools, pilot materials were developed to support the teaching of biostatistics at a medical university. The authors conducted surveys among students of faculties of medicine in order to evaluate the materials used in terms of quality and usefulness. The article presents the analysis of the results obtained.

It is known that if C is a semi-Chebyshev closed and approximately compact set in a Banach space X, then the metric projector πC ...

The method is used to analyze various complex processes without using formal laws governing the same. It is particularly suitable for a general analysis of fluid transfer (liquids and gases) in the human body. This paper mainly serves as an overview of selected applications, mostly those emerging in the recent years, and includes a discussion of the mathematical fundamentals of dimensional analysis together followed by its critical analysis. Containing detailed calculations of two examples, the paper also serves as training material in the area of the computational method of the dimensional analysis algorithm.
