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.

This article follows two important interconnected aspects. On one hand, it investigates whether the political factors represented by the presence of ethnic minorities can be a catalyst for tourism development in cross-border regions, in addition to the development of transport infrastructure. On the other hand, it offers a comparative analysis and territorial diagnosis of the Bihor-Hajdú–Bihar and Maramureş–Zakarpattya cross border regions, analyzing the main tourist indicators and the advances made in the development of the transport infrastructure with a role in the development of tourism. The paper is based on desk and quantitative research involving national and regional statistic data. Research on the literature regarding Hungarian–Romanian and Romanian–Ukrainian borderland was also realized, in order to conduct comparative analysis useful to identify and evaluate the factors linked with tourism development. Using a multiscale approach, the objective is to determine if there is a correlation between the development of the transport network and the increase in tourist traffic. The results show that transport infrastructure plays a critical role in ensuring the connections of border regions. Although the two regions are contiguous, there is an obvious difference in cross-border traffic due to the presence of two different types of border. The transport network and tourism situation in Bihor has improved in the last years, especially under the impact of cross-border cooperation, but the accessibility remains relatively low. In Maramureş, the development of cross-border connections is based on cultural exchange, and less on economic relations. Transport accessibility is a strong point of the Hungarian–Romanian borderland and represents an obstacle for the development of tourism in the Romanian–Ukrainian borderland.

The present study describes the results of air quality analysis and surfaces inside the Orthodox Church in Oradea City, Romania, a wooden monument (BH-II-m-B-20958), originally built in the village Letca from Sălaj County and displaced in 1991 to the campus of the University of Oradea. The paper focuses on the degree of microbial and fungal contamination of surfaces and air inside the wooden church. It also identifies various microbial species with potential risk on the health of parishioners and those in charge of maintaining the halidom.

The purpose of the following paper is to debate the cross-border shopping tourism activities taking place at the external borders of the European Union in Poland and Romania. The work focuses on a comparative analyses of three borders from Poland and three borders from Romania. They had a similar history, underwent a period of political and economic transformation and both countries joined the EU in a short space of time. The research is composed from a theoretical and empirical approach. The theoretical research results show similarities in the evolutions of cross-border shopping tourism activities from both countries. The empirical research updates the situation of cross-border shopping tourism activities. The results show a different evolution of this kind of tourism activities, which has been more predominant at the Polish borders than at the Romanian border, mainly motivated by the stronger market differences existing between Poland and its neighbours, than between Romania and its neighbours. The economic motivators are still strong with a focus of customers on better price benefits and discount opportunities. The leisure elements, although not predominant are present, mainly in Poland, the customers being mainly motivated by the pleasure emerged from the shopping activity. In terms of shopping, the dominant role is played by the shopping, in their old forms (bazaar, local market or a transformed department stores) or their new forms (commercial centres or malls), increasingly incorporating also elements of leisure.

This study is an attempt to monitor the indoor microclimate and the microbiological contamination of some indoor objects inside a wooden Orthodox church. Standard microbiological techniques were used for the isolation and identification of the fungi present in the dust of the superficial surface of the paintings chosen to be investigated for biodeterioration. Samples were taken from approximately 1 cm 2 of the surface of the analysed paintings (cotton canvas, wood, on primer) using the cotton swab method. The cultures of fungus isolated from the studied paintings were identified based on their morphological and microbiological characteristics. The identity of isolates was established, based on the smear microscopic examination, using the lactophenol blue cotton staining procedure. Based on the morphological characteristics of conidiophores, the following fungal genera were determined to be present in the dust of the studied paintings: Streptomyces sp., Arthrographis sp., Beauveria sp., Aspergillus sp., Penicillium sp., Alternaria sp., Cladosporium sp., and Streptomyces sp. The current state of paintings, influenced in time by temperature, humidity, brightness, microbial contamination, and other factors, was investigated and mapped. The detailed analysis contributes to the conservation stage of the historic monument investigation, enhancing the existing data in the environments destined for the conservation of valuable objects. The continuous monitoring of the indoor microclimate, together with the maintaining of good hygiene, cleaning conditions and proper ventilation, could successfully contribute to the slowing down of painting degradation within the wooden church monument.
