    Opis:
    The perception of a person with a disability is determined by qualities that are commonly desired in society. In this text, we have attempted to analyze to what extent the contemporary normalization paradigm, which assumes the necessity of treating every person with the dignity that belongs to them, while respecting their rights, translates into social perceptions of people with intellectual disabilities. For this we used a diagnostic survey, conducted among non-humanities (technical programs) students, i.e. young adults with theoretically less knowledge of psychology, sociology, or pedagogy, which could significantly affect what they think about people with intellectual disabilities. In the text, we also touched on social barriers, social tasks, and opportunities for people with intellectual disabilities.

    Opis:
    Collagen is a valuable biopolymer in many fields, especially in biomedical sciences. Thanks to its biodegradability and high biocompatibility, it is a desirable material for applications that require contact with the human body. There are many sources of collagen, of which marine-origin collagen has become an important one in recent times. Pure collagen has poor stability and is sensitive to the effects of heat and other external factors. The cross-linking process can improve the properties of collagen materials. Many different methods of cross-linking can be distinguished, including chemical ones. In this study, we were concerned to obtain collagen films modified with glutaraldehyde (GTA). The influence of this additive on the chemical, mechanical, swelling, and hydrophilic properties of the biopolymeric matrix was evaluated. Two different concentrations of collagen were used, as well as three different concentrations of GTA. Results of the analysis showed that the properties of the obtained films were affected by the addition of even a small amount of cross-linker. Spectroscopic measurements indicated minor changes that reflect interactions between GTA and the collagen matrix. Mechanical tests showed changes for modified samples in values of tensile strength, breaking force, and elongation at break. The hydrophilicity decreased slightly for films with GTA. The durability of the modified samples in the swelling test increased. Differences between 1% and 2% collagen films with additives were also observed. The GTA-obtained fish collagen films can be promising materials for biomedical applications.

    Opis:
    Over the last three decades, an increasing interest in the preparation of new materials for wound healing has been observed. Collagen is a widely used biomaterial, and especially fish skin collagen is more and more popular among scientists. This study aimed to obtain thin films from native fish skin collagen and collagen cross-linked with tannic acid. Infrared spectroscopy, mechanical test, topographic imaging, and swelling test were used to characterize the features of the mentioned films. Statistical evaluation of the results was conducted with the Q-Dixon test. Infrared spectroscopy analysis showed that in the IR spectra of examined biomaterials, there are slight shifts in band positions after tannic acid cross-linking. The mechanical properties of the cross-linked material were different from those of the native collagen film. The Young’s modulus was higher for cross-linked collagen, whereas the elongation at break was lower than for pure collagen. The swelling of the collagen films increased after cross-linking with tannic acid. Swelling tests indicated that collagen cross-linked with tannic acid absorbs more water than before cross-linking. The properties of collagen films were significantly improved after tannic acid cross-linking. All alterations can be a result of collagen cross-linking by tannic acid, probably by forming hydrogen bonds between collagen and tannic acid.
