Accidents are inherent elements of human activity, and engineers have strived to develop safety systems to safeguard people against accidents, which are often random and unpredictable. Helmets have become the most popular means of protection over the years. They have undergone significant modifications, evolving into effective and advanced tools for head protection. Unfortunately, because helmets remain optional for bicycle users, some individuals choose to ignore safety guidelines. Methods: This research employed a survey method conducted among the residents of the Poznan agglomeration to determine the reasons behind the low adoption of helmets. A questionnaire consisting of 15 questions was distributed to 173 users of two-wheeled vehicles, including motorbikes, bicycles, mopeds, and electric scooters. Results: The findings revealed that only 41.4% of men declared using helmets, with 24.4% of women doing so. Additionally, 44.4% of the helmets in use were new, while the remaining 55.6% were purchased second-hand. Conclusion: The research indicates that individuals are more likely to wear protective helmets on older two-wheelers, and helmet usage is higher in larger cities. Therefore, it is essential to focus bicycle helmet educational campaigns on children and teenagers to improve safety awareness and encourage helmet usage.

Wypadki są nieodłącznym elementem działalności człowieka, dlatego inżynierowie starają się opracować systemy bezpieczeństwa, które chronią ludzi przed wypadkami, które często są przypadkowe i nieprzewidywalne. Kaski stały się na przestrzeni lat najpopularniejszym środkiem ochrony. Przeszły istotne modyfikacje, ewoluując w skuteczne i zaawansowane narzędzia ochrony głowy. Niestety, ponieważ kaski pozostają opcjonalne dla użytkowników rowerów, niektóre osoby ignorują wytyczne dotyczące bezpieczeństwa. Metody: W badaniu wykorzystano metodę ankietową przeprowadzoną wśród mieszkańców aglomeracji poznańskiej w celu ustalenia przyczyn małej ilości noszonych kasków. Kwestionariusz składający się z 15 pytań rozesłano do 173 użytkowników pojazdów dwukołowych, w tym motocykli, rowerów, motorowerów i hulajnóg elektrycznych. Wyniki: Z przeprowadzonych badań wynika, że używanie kasków deklaruje jedynie 41,4% mężczyzn, zaś kobiet 24,4%. Dodatkowo 44,4% użytkowanych hełmów było nowych, a pozostałe 55,6% kupionych z drugiej ręki. Wnioski: Badania wskazują, że osoby częściej noszą kaski ochronne na starszych jednośladach, a ich użycie jest częstsze w większych miastach. Dlatego istotne jest skupienie kampanii edukacyjnych na temat kasków rowerowych na dzieciach i nastolatkach, aby zwiększyć świadomość bezpieczeństwa i zachęcić do używania kasków.

The article presents the possibility of increasing the production efficiency in an enterprise dealing in the production of lounge furniture. The literature review shows that Poland is the sixth country in the world in the amount of furniture production. It is also one of the leading exporters of upholstered furniture in Europe. Each year, the value of furniture sales production increases by a few percentage points. Due to the constantly growing customer orders, many companies in this industry are struggling with delays in delivering products to customers. This problem also occurs in the analyzed company. While analyzing the production process, the occurrence of a large number of non-conformities was also noticed. An analysis was carried out to indicate the number of non-conformities and the place of their occurrence. The FMEA analysis was used, which indicated which non-conformities are the most important, and the 5Why method, which allowed to indicate the cause of their occurrence. The analysis of production processes showed which activities do not bring added value and how they can be eliminated at no cost. All these measures contributed to increasing the efficiency of the production of lounge furniture.

Additive manufacturing in recent years has become one of the fastest growing technologies. The increasing availability of 3D printing devices means that every year more and more devices of this type are found in the homes of ordinary people. Unfortunately, air pollution is formed during the process. Their main types include Ultra Fine Particles (UFP) and Volatile Compounds (VOC). In the event of air flow restriction, these substances can accumulate in the room and then enter the organisms of people staying there. The article presents the main substances that have been identified in various studies available in literature. Health aspects and potential threats related to inhalation of substances contained in dusts and gases generated during the process are shown, taking into account the division into individual types of printing materials. The article also presents the differences between the research results for 3d printing from individual plastics among different authors and describes possible causes of discrepancies.
