Poor air quality inside museums is one of the main causes influencing the state of conservation of exhibits. Even if they are mostly placed in a controlled environment because of their construction materials, the exhibits can be very vulnerable to the influence of the internal microclimate. As a consequence, museum exhibits must be protected from potential negative effects. In order to prevent and stop the process of damage of the exhibits, monitoring the main parameters of the microclimate (especially temperature, humidity, and brightness) and keeping them in strict values is extremely important. The present study refers to the investigations and analysis of air quality inside a museum, located in a heritage building, from Romania. The paper focuses on monitoring and analysing temperature of air and walls, relative humidity (RH), CO2, brightness and particulate matters (PM), formaldehyde (HCHO), and total volatile organic compounds (TVOC). The monitoring was carried out in the Summer–Autumn 2020 Campaign, in two different exhibition areas (first floor and basement) and the main warehouse where the exhibits are kept and restored. The analyses aimed both at highlighting the hazard induced by the poor air quality inside the museum that the exhibits face. The results show that this environment is potentially harmful to both exposed items and people. Therefore, the number of days in which the ideal conditions in terms of temperature and RH are met are quite few, the concentration of suspended particles, formaldehyde, and total volatile organic compounds often exceed the limit allowed by the international standards in force. The results represent the basis for the development and implementation of strategies for long-term conservation of exhibits and to ensure a clean environment for employees, restorers, and visitors.

The quality of the indoor microclimate in museums is a problem of great interest to the contemporary society, given that it is in close connection with the health and comfort of visitors and employees, as well as with the integrity of the exhibits. Taking into account the fact that museums are places that have a special role in the community’s life and therefore attract a very large number of visitors of all ages, a very important issue is to determine the degree of safety that the indoor microclimate presents. Thus, the quality of the indoor microclimate was investigated inside an iconic museum in Romania, dating back to the 19th century, because pollutants from external or internal sources of the building, generated secondary, often anthropogenic, as a tendency to defend/adapt to climate change (CC), contribute to both local and regional pollution, but also lead to challenges in identifying links between air quality (AQ) and and climate change (CC). The methodology used was based on monitoring the main parameters of the microclimate (temperature, relative humidity and CO2) over a period of between October 2020 and March 2021, 21 weeks, as well as on determining the microbiological contamination of the air and some indoor exhibits located in three different areas of the museum. At the same time, the study aims to identify cheap, easy to implement and non-invasive solutions for removing fungi identified on exhibits for long-term preservation and reducing the risk of various pathologies in humans following prolonged exposure. The results obtained show that the indoor microclimate in the old heritage building favours the development of fungi, which have a high degree of contamination of the air (over 800 CFU/m3) and of the exhibits, representing a potential risk for the health of the visitors and museum workers. Thus, six species of yeast and five different fungi genera were identified in the air, while on the exhibits were individualised six fungi genera, a species of yeast and a bacterium. The most viable solution for cleaning materials, prolonging their lifespan and reducing the risk of disease in humans was represented by the use of essential oils (EO). Three essential oils (lavender, mint and lemon) were applied on an exhibit with five different microorganism genera, and it was observed that they have the ability to inhibit the spores from moulds and bacteria, being a very good alternative to the usual chemical treatments that are used in the cultural heritage field.

The Jewish architectural heritage is and will remain an integral part of the local cultural heritage, but part of it still needs to be discovered, rehabilitated, maintained and valued. For Oradea, a Central–Eastern European city, this challenge is very specific because the Jewish communities before World War II were very strong and prosperous and because of the current desire to assert the city in the tourism market through urban regeneration. The Jewish community of Oradea had an important representative in Éva Heyman, a child of the Holocaust, nicknamed “Anne Frank of Transylvania”, which became famous. At the age of 13 years, Éva Heyman kept a diary during the Jewish ghettos in Oradea. In addition to the diary, her story is about the house where she grew up, built in the Art Nouveau style at the center of Oradea. Even though this house is of inestimable value from an aesthetic and cultural point of view, very little is known among the local population. Moreover, it is not listed as a historical monument, and its current state of preservation is precarious. With the increasing importance of preserving cultural heritage and computer graphics development, the digitization of historical buildings began to be used more and more for evaluation, preservation and promotion. This paper attempts to highlight the story of Éva Hayman and the house where she grew up. The paper further presents the innovative methods by which it is desired to achieve the presented goal for this architectural jewel. The results show that three-dimensional digitization methods are powerful tools for preservation and use for the benefit of the general public, education professionals, administrators and investors, art historians, restorers, etc., who are concerned with the collection preservation, exploration and mediation of the Jewish cultural heritage.

Storytelling maps have recently become increasingly popular, as they provide access to otherwise inaccessible places or services. A printed map is a tangible object which mediates the storytelling process. This particular map, featuring the adventures of Pintea Viteazul (Pintea the Brave), a Romanian folk-hero, is designed to enhance tourist experiences during outdoor activities in a mountain area with relatively accessible infrastructure and scenic features: the Mara Valley and Creasta Cocosului (Maramureş, Romania). The main research questions revolved around the experience design. The research was based on designing and testing a specific storytelling map for mountain tourism. The main stages of development were the experience design and the map itself. Focusing on a complex geographic location famous for its volcanic relief and folk tales, it tells the story of the mountain by tracing a parallel between geological features and a national legend.

Chitosan is a natural polymer, which presents, according to studies made up to present, low toxicity and goodbiocompatibility. Recent studies are focused not only on its antimicrobial effects on textiles, because this polysaccharideleads to improvements such as: shrink resistance, dye uptake etc. Two Romanian traditional shirts were non-invasively tested by applying Chitosan and by investigating the SEM images,before and after applying the chitosan. The paper underlines the surface modifications of tested textiles using chitosan.The odd agents on the fibres surfaces were removed and the limitation of the number of microorganisms was observed
