Digitalization offers opportunities for youth to engage in a wide range of digital-mediated civic activities, thereby fostering their digital citizenship. While embracing the potential of digital technologies, it is crucial to have a realistic understanding of the practical, ethical, and cultural considerations for implementing youth discourse in cultural heritage management and empowering youth initiatives in decision-making. Little research has focused on assessing youth digital participation in cultural heritage management for its impacts on fostering inclusivity, enhancing the levels of youth engagement, gauging the potential of digitalization, and facilitating youth initiatives. This paper fills the gap by developing an assessment framework for youth digital participation, comprising four criteria and thirty-five indicators. These indicators were validated through expert consultation and multivariate analysis and categorized into four groups based on their levels of priority. The framework provides detailed guidelines for applying these indicators across different phases of participation—envisioning, monitoring, and evaluating. Additionally, four recommendations derived from the framework provide suggestions on critical aspects of youth digital participation and guidelines to foster the impact of youth engagement in future participatory practices in cultural heritage management.

<div><div>The durability of historical building envelopes is affected by changing climate conditions. The impact of climate change on degradation phenomena can be assessed by means of hygrothermal simulations. Often, studies only use a single climate projection, and thus only consider a single evolution of the climate system. However, an ensemble of multiple climate projections is necessary to assess the uncertainty of the results. This paper presents an overview of three types of uncertainties in climate projections (i.e. uncertainty due to the greenhouse gas emission scenario, climate variability, and the climate model itself), and their influence on the degradation of building envelopes. In total, the study includes the results of 16,088 1-dimensional hygrothermal simulations of solid masonry walls, prior to and after the application of a thermal retrofit, in Delphin 5 and 6. Firstly, scenario uncertainty is studied for 3 emission scenarios (one climate model) in Brussels (Belgium). The ensemble members agree on the change in freeze-thaw damage. The spread of the percentage of cases, i.e. combinations of building and exposure parameters, with an increasing freeze-thaw risk is 6%. Though, the change in wood decay is uncertain with a spread of 51%. Secondly, climate variability may cause a large uncertainty in freeze-thaw damage. In Ottawa (Canada), the spread between ensemble members (i.e. 15 realisations of one model) of the change in freeze-thaw damage goes up to 100% for individual cases. Thirdly, model uncertainty is assessed in Hamburg (Germany). Towards the end of the 21<sup>st</sup> century, the spread in percentage of cases is ca. 20% for increasing freeze-thaw damage, mould growth, and wood decay. When evaluating the change for global warming level +1.5°C, +2°C, and +3°C together, the spread increases. The risk for freeze-thaw damage in the masonry increases (decreases) in 0–52 % (8-77%) of the simulated cases. For mould growth on the interior surface of uninsulated walls, the risk increases (decreases) in 0-19% (0-10%) of the cases. Wood decay of embedded beam heads is projected to increase (decrease) in 14-42% (0-18%) of the cases. Furthermore, this paper presents three approaches on how to assess the impact of climate change on historical buildings. The generic response-based degradation atlas answers the question ‘<em>How does climate change impact the degradation risks in the overall collection of historical buildings?’.</em> Secondly<em>,</em> case-specific decision trees are used to assess which cases are most at risk, and to identify how climate change and parameter variations affect degradation risks.

Ionizing radiations, commonly applied as diagnostic tools in Cultural Heritage (CH) field, are also proving effective for eliminating biodeteriogens (insects, fungi, bacteria and molds) responsible for the degradation of CH artifacts and often harmful for restorers, archivists and librarians. The use of ionizing radiations, such as gamma rays, for CH treatments is spreading in many countries. However, some CH operators remain resistant due to insufficient knowledge about the potential physico-chemical modifications (secondary effects) induced by radiation. This work aims to investigate and compare the effects of irradiation parameters (such as absorbed dose and dose rate) on old paper samples and new pure-cellulose paper, chosen as a reference model material. Absorbed doses up to 8 kGy have been used, as these values are commonly agreed upon for the preservation treatment of CH artifacts and are generally effective for biodeteriogens removal. Optimizing irradiation conditions helps to minimize secondary effects (such as oxidation, depolymerization or color changes), thereby increasing the reliability of the process and boosting confidence among CH operators. The secondary effects were analyzed using various physico-chemical characterizations (Fourier Transform Infrared spectroscopy, Raman microscopy, viscosimetric and colorimetric analysis) on old and new paper samples. The results indicate varying behaviors, correlated with paper composition, sample age and irradiation parameters, towards gamma radiation. This groundbreaking study not only confirms the efficacy of gamma irradiation treatments but also provides essential data that will aid in the development of optimized best practice protocols and guidelines for non-destructive and minimally destructive methods applied to real case studies and treatments.

The deterioration evaluation of grotto rock mass is an important foundation for its protection and reinforcement. In this study, the thermal effusivity and crack parameters of rock mass were obtained using infrared thermography (IRT), and a set of index system for the deterioration evaluation of rock mass was established. Based on the comprehensive weighting method and improved technique for order preference by similarity to ideal solution (TOPSIS), the evaluation method of grotto rock mass deterioration based on infrared thermography (EGD-IRT) was constructed. This method quantifies and classifies the deterioration level of rock mass using the deterioration index, which was validated and applied. The results indicate that the deterioration index of grotto rock mass can comprehensively reflect the damage to the internal structure and loss of external material of rock mass, and it is consistent with the comprehensive evaluation result of P-wave velocity and mass. Powdering, hollowing and cracks are the main reasons for the spatial heterogeneity distribution of the deterioration index of grotto rock mass. Among them, the cracks generally control the deterioration zoning of rock mass, with a negative correlation existing between the bulk density of cracks and the average deterioration index in different regions. The EGD-IRT can comprehensively analyze the deterioration status of rock mass from both the overall and local levels, thus determining the deterioration grade and unstable parts of grotto rock mass. The results of this study provide valuable guidance for the conservation of grotto temples.
石窟岩体的劣化评价是其保护和加固的重要基础。本研究利用红外热成像技术（IRT）获得了岩体的热辐射率和裂隙参数，并建立了一套岩体劣化评价指标体系。基于综合加权法和改进的理想解相似性排序优先技术（TOPSIS），构建了基于红外热成像技术的石窟岩体劣化评价方法（EGD-IRT）。该方法利用劣化指数对岩体劣化程度进行量化和分类，并进行了验证和应用。结果表明，石窟岩体的劣化指数能全面反映岩体内部结构的破坏和外部物质的损失，与 P 波速度和质量的综合评价结果一致。粉化、空洞和裂隙是造成石窟岩体劣化指数空间异质性分布的主要原因。其中，裂隙一般控制着岩体的劣化分区，裂隙的堆积密度与不同区域的平均劣化指数呈负相关。EGD-IRT 可以从整体和局部两个层面综合分析岩体的劣化状况，从而确定石窟岩体的劣化等级和不稳定部位。研究结果为保护石窟寺提供了宝贵的指导。

The mural paintings are prone to deterioration due to surface powdering, cracking, and loss of painted layers, so coating the mural paintings with eco-friendly benign materials is urgent for consolidation and restoration purposes. Minimizing particle size to the nanoscale results in better properties compared to their bulk equivalents. This paper discussed the utilization of chitosan (Cs), chitosan nanoparticles (CsNPs), and silica-loaded chitosan (SiO2@CsNPs) to improve the consolidation of the painting surfaces on the facade of Neb-Maat-Ra's palace gate, which is a monument to King Ramesses IX (1125–1107 BC) in Egypt. Biopolymers are eco-friendly materials and considered an effective alternatives to synthetic coatings in the consolidation of cultural heritage. Cs has the potential to be a substitute for conserving well-painted paintings and stone, the presence of amino groups in chitosan's structure confers high biological activity and reactivity. CsNPs are more attractive compared to bulk chitosan, moreover, the incorporation of silica (SiO2) into CsNPs created good hydrophilic/hydrophobic balance and enhanced the mechanical scrub resistance. Digital Microscope, Scanning Electron Microscopy (SEM), Portable X-Ray Fluorescence Spectrometer (pXRF), (FTIR ATR), and Colorimetric measurements were used in performing the study. X-ray fluorescence was utilized to determine the compounds used in the facade of Neb-Maat-Ra's palace gate. Limestone served as the support, and hematite was used to create red pigment. The results showed that CsNPs and SiO2@CsNPs were superior to traditional Cs, however, the best result was observed for SiO2@CsNPs. Our study revealed the potential of CsNPs and SiO2@CsNPs in the protection of the facade of Neb-Maat-Ra, the son of King Ramesses.

A multi-disciplinary research campaign was conducted on the painting Country Huts Among Trees by Vincent van Gogh. The painting belongs to the John Paul II Collection and is currently on deposit at the Museum of John Paul II and Primate Wyszyński, owned by the Archdiocese of Warsaw. The painting, considered a significant work from Van Gogh's early Dutch period, reflects his mastery of oil technique and his fascination with rural life. It is characterized by a specific, dark and subdued palette that conveys the expressive and dramatic mood of the landscape from the early 1880s.
This contribution presents the findings from the scientific research campaign carried out on the painting during 2021–2024. The analyses included technical photography in visible, infrared, and ultraviolet ranges, followed by spectroscopic and microscopic analyses. These investigations revealed the presence of pigments such as bone black, carbon black, chrome yellow, iron-based earth pigments, lead white, Prussian blue, and vermilion.
This investigation has been very challenging due to the absence of any work by Vincent van Gogh in Polish museum collections. However, analysis of the painting has provided an interesting opportunity to study Van Gogh's materials and techniques within a broader context of art history and painting technology. The results have provided support to art historical research related to the painting's authenticity and significance.

The development of melodrama during the 16th and 17th centuries brought the architects to the elaboration of a different variety of geometry for the main halls of opera theatres. Unfortunately, nowadays there are only a few theatres designed and built during the Baroque period since most of them are completely destroyed. The architectural investigations carried out on two case studies belonging to the Galli Bibiena family have been taken over for a complete acoustic assessment. The digital models related to the Nancy and Tajo opera theatres were built from the outcomes and discoveries on the historical resources consisting of drawings, sketches and general documents. The digital models were used for the acoustic simulations carried out on the main acoustic parameters that evaluate the quality of speech and music inside these two case studies. The simulated results indicate that the acoustic response in the Nancy and Tajo opera theatres is very similar to each other, although the small difference between the two theatres is mainly in function of the volume size rather than other architectural features. Overall, the simulated values are found within or closer to the optimal range set by the criteria, which support the assumption of speech and musical performances given in the royal palaces, the place in which they were erected.

Overall, the simulated values are found within or closer to the optimal range set by the criteria, which support the assumption of speech and musical performances given in the royal palaces, the place in which they were erected.</div></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"70 ","pages":"Pages 302-311"},"PeriodicalIF":3.5,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142528683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plasma Enhanced Chemical Vapor Deposition (PECVD) of SiOx thin films has been applied to the stone surface under laboratory conditions in order to assess its feasibility as an alternative method for stone protection. SiOx thin layers were deposited on oolitic limestone lithologies known to have been used for the construction and restoration of the Batalha Monastery in Portugal surface by PECVD from tetraethoxysilane (TEOS) as the reaction precursor, in capacitively coupled parallel-plate reactor. The thickness, morphologies and chemical properties of the deposited film were characterized by attenuated total reflectance -Fourier transform infrared (ATR-FTIR) spectroscopy and scanning electron microscopy (SEM+EDS). Laboratory simulated decay and natural aging tests were implemented to evaluate the protective effect of the deposited micron-size SiOx thin films. Results suggested that, due to the good barrier effect, SiOx films were able to isolate the stones from aggressive acidic solution, thus reducing possible dissolution-related damage. Natural aging tests proved that SiOx thin films were also able to inhibit to a high extent bio-colonization while, at the same time reducing soiling of the stone appearance. Durability and wetting property of this SiOx thin film were preliminarily assessed. This research tested, for the first time, the feasibility of applying micron-size SiOx film quickly and directly via cold plasma deposition and its versatile protection performance on carbonate stone.

Electrochemical and biological analyzes were carried out on iron-wood composite archaeological objects from the “KASBA-OUDAYA” site in Morocco in 10 % PEG-200 solutions. Electrochemical measurements of steel combined with wood were made possible thanks to a proposed steel-wood configuration, with characterization of the surfaces after natural aging tests focused on the steel-wood interface by scanning electron microscope. The Mohr and Nephelometric method allow the determination of chloride and sulfate ions. While the biological study is ensured by isolation and enumeration of strains. The results revealed that the presence of wood in the PEG-200 solution decreased the pH of the solution and accelerated corrosion of steel. At the interface, we observe the development of pitting corrosion zones. In addition, PEG-200 solutions constitute a favorable environment for the proliferation of microorganisms.
