    Opis:
    Metody szybkiego prototypowania wykorzystuje się w wielu dziedzinach. Od kilku lat zauważa się zainteresowanie tymi technologiami również w medycynie, protety-ce i inżynierii tkankowej oraz biomedycznej. Tak szerokie zastosowanie metod szyb-kiego prototypowania związane jest ze względnie niską ceną wytworzenia rzeczywi-stego modelu 3D oraz szybkością procesu. W medycynie rekonstrukcyjnej i implan-tacyjnej ceni się je głównie za możliwość dostosowania do indywidualnych potrzeb pacjenta. Do powszechnie stosowanych metod zalicza się stereolitografię, laserowe spie-kanie proszków, osadzanie stopionego materiału i druk 3D. Artykuł zawiera przegląd metod szybkiego prototypowania w odniesieniu do za-stosowań w nowoczesnej medycynie, implantologii i inżynierii tkankowej, której pro-dukty (rusztowania tkankowe) umożliwiają regenerację uszkodzonej tkanki pacjen-ta lub całego narządu. Dodatkowo przedstawiono grupy materiałów, ze szczególnym uwzględnieniem polimerów i biomateriałów polimerowych, które stosuje się z suk-cesem w wyżej wymienionych aplikacjach.

    Opis:
    Background The population ageing phenomenon is mainly attributable to the increasing proportion of people >60 years of age. This demographic situation requires more attention to the needs of the elderly. Given the lack of effective methods to expand the knowledge of and increase sensitivity to elderly people’s problems, especially among the younger generation, an attempt has been made to use virtual reality (VR) to prepare an educational tool focused on these problems. This paper will focus on the use of VR in depicting fundamental problems in the daily live of older people. Material and Methods For project purposes, a questionnaire (26 question) was developed, concerning data on socio-demographic situation, health and physical conditions; social, living and housing support needs. Additionally, qualitative interviews were conducted with elderly people regarding their needs about housing arrangements and daily activities. It was distributed to 100 people, 34 completed questionnaires were obtained from 30 women and 4 men. The study results were intended as information that would provide the basis for developing VR scenarios, not for the epidemiological purposes. Results The mean age of the respondents was 73.7±7.5 (60‒86 years). Different situations, as heavy housework, lifting/carrying heavy objects, lifting hands above the shoulder level, bending and squatting were identified that pose problems for elderly people. Based on these results, 3 scenario proposals were prepared, including situations: in the bathroom, in the supermarket, on a trip to the city. These scenarios were used to prepare the exercises in VR in the frame of European project – the Mixed Reality on Universal Design’s Secret Service (Mr. UD) Project. Conclusions The use of immersive technology such as VR can be beneficial for young people to be able to see perspectives of the elderly. Students from various fields (medicine, nursing, future engineers, designers, sociologists, etc.) may feel like the elderly and experience their daily challenges.

    Opis:
    PMMA-based bone cements are commonly used for implant fixation or as bone void fillers. Hydroxyapatite added as a filler to bone cement may positively affect the final properties of the material, in particular its biological properties. In this study, the preparation of poly(methyl methacrylate)-based bone cements with incorporated hydroxyapatite (HAp) is reported. The purpose of this article is to examine the proper-ties of bone cements enriched with HAp filler (the concentration of 3wt% and 6wt%) and reveal the changes in the composites properties (chemical structure, surface morphology and distribution of HAp in the composite matrix, moisture absorption, hardness in Shore D scale) during the long-term incubation in the PBS (phosphate-buffered saline) solution at 37°C. The incubation lasted up to 21 days, but only the period when the changes actually occurred was analysed. The studies have shown that the samples containing HAp absorb more moisture and have a lower hardness. These characteristics vary depending on the concentration of HAp. There is no elution of HAp and ZrO2 from the composite during the incubation. The surface morphology and chemical structure do not change during long-term studies. The obtained bone cements are characterized by high stability in the PBS solution.

    Opis:
    Background This paper presents an overview of a pilot study focused on testing the effectiveness of immersive virtual reality (VR) exercises, within extended reality experiences, in increasing awareness and empathy among university students towards pregnant women, elderly people, people in wheelchairs, and people with some sort of sight impairment. The extended reality experience was designed to simulate various scenarios that reflect the experiences of people from diverse backgrounds, to promote a better understanding of different perspectives and social issues related to some of the challenges tackled by people whose limitations are many times overlooked. Material and Methods A design-based research methodology was applied and qualitative and quantitative data were collected in samples of 20 students from 3 countries. Results Overall, the results suggest that immersive VR applications can be an effective tool in increasing awareness and empathy among higher education students. The use of VR technology can create a sense of presence and immersion that allows students to experience situations that they may not have encountered otherwise. The results attained with the immersive experiences have provided evidence that these solutions can foster a greater understanding of different perspectives and promote empathy towards individuals from diverse backgrounds. Conclusions Ongoing research correlated with the Mixed Reality on Universal Design’s Secret Service (Mr. UD) project results is already expanding on these findings by testing the effectiveness of VR applications in different contexts and with larger and more diverse samples. Additionally, the research conducted has provided relevant evidence that suggests that VR applications and their inclusion in training programs may help promote behavior change and reduce prejudice and discrimination towards marginalized groups.

    Opis:
    Background Virtual reality (VR) has the potential to be a powerful tool in promoting empathy towards inclusion, particularly for individuals with impairments such as mobility difficulties, vision deficits, or autism but also about pregnancy, which can create temporary difficulties. By immersing users in simulated environments that replicate the experiences of those with different abilities, VR can create a sense of understanding and empathy for those who face challenges in their daily lives. For example, VR experiences can simulate the experience of navigating space as someone with a mobility impairment, providing a new perspective and appreciation for the difficulties that others face. Similarly, VR experiences can simulate the experience of vision impairment, pregnancy, or autism, providing a window into the challenges faced by those with these conditions and fostering empathy and understanding. Material and Methods During the development of this study, field experts were consulted to ensure the robustness of the methods employed. Then, questionnaires were specifically developed to explore disabilities and challenges related to inclusion and were administered to a large population. Additionally, guided interviews were conducted with individuals who possess specific impairments to gather first-hand insights. Results The results obtained from the questionnaires and interviews provide a comprehensive overview of the inclusion challenges that necessitate attention and resolution. By drawing on the expertise of both experts and individuals with lived experiences, a holistic landscape of inclusion challenges has been established. Conclusions The VR emerges as a powerful tool for promoting inclusion and fostering understanding among individuals. Its capacity to create immersive experiences that facilitate empathy has the potential to reshape society into a more compassionate and empathetic one. By leveraging the unique capabilities of VR, we can bridge the gap between different perspectives, fostering greater understanding, acceptance, and inclusivity.
