The article is devoted to the questions of cultural heritage preservation by creating the digital collection of book monuments. The original documents are monuments of book culture and their dilapidated state requires careful handling, splitting of documents for scanning is extremely undesirable. The market does not present the equipment for contactless scanning of books without embroidering, therefore an algorithm that allows digitalizing book monuments in a contactless way has been developed. The technique has been constructed using an algorithm based on the projection of the light grid on the object scanned. The authors propose a sequence of actions consisting of image processing and comparing the results between two images. The first snapshot determines the initial parameters of the grid; the second snapshot determines the actual distortion of the test snapshot. Subsequent mathematical processing allows getting scanned images without absence of geometric distortions of the scanned page due to the system of using the two-dimensional array of corrections. The application of the system has been modeled on the example of «The legend of the destruction of Siberian cities of Tara and Tyumen by the lesser Tatars / / Collection of moral stories, words, lives and other articles [hand.]». The evaluation parameters of the simulation result have been the following: text distinctness, absence of geometric distortions, color quality, uniformity of document scanning quality within a single book, etc., as checked and recognized as high by the experts.The experience described opens possibilities of book monuments digitization using the new algorithm. The development of the system is aimed at expanding the database of objects of material culture to be digitized, perfecting the software, improving the quality of digital images, as well as the capabilities of image recognition and search for the document itself and information it contains.

Cultural Heritage Preservation

Recently, in line with the increased attention paid to cultural tourism in general and to religious tourism in particular, researchers and practitioners have become increasingly interested in the analysis of various aspects related to cultural heritage in order to capitalize on its value by means of its interpretation, thus providing beneficial effects both for tourists and for tourism’s sustainable development. The aim of this research is to analyze the extent to which the methods of interpretation of the religious cultural heritage: guiding tours, quality reception, and relic worship influence the satisfaction of tourists participating in the “Saint Parascheva” pilgrimage, held annually by the Metropolitan Cathedral in Iasi. The data were collected by means of a survey (N = 932) and the information was processed by using the SPSS version 25 program. Our results indicate the significant influence that the potential to worship relics has on pilgrims’ satisfaction compared to other interpretation methods, such as the relationship with the Cathedral’s staff or the possibility of participating in guided tours. Pilgrims’ satisfaction is also perceived differently depending on certain aspects of their socio-demographic profile, i.e., their age and the perceived faith level. This study is relevant for researchers, managers, and students interested in the field of cultural heritage interpretation in genera, and in the field of religious heritage in particular, and could significantly contribute to improving pilgrims’ satisfaction as well as cultural heritage preservation.

Conservation Interventions

In the cultural heritage preservation of medieval buildings, it is common to find plaster walls covered in lime, which previously were painted in polychromy. The conservation interventions usually try to remove the whitewash, whilst maintaining the original color of the painted wall as much as possible. However, there is no agreement on which cleaning technique best preserves the original appearance of the colored plaster. Different pigments found below the lime layer may behave differently depending on the cleaning technique used. Usually, colorimetric or photometric area-based measurements are carried out to study the color of the cleaned areas to compare with their original color, obtained from pre-made plaster probes. However, this methodology fails when the mean color difference is not enough to fully characterize the changes in texture and color appearance. This study presents a set of experiments carried out using two different pigments (cinnabar and malachite) covered with lime, and treated with nine different cleaning techniques on plaster probes prepared according to medieval techniques. We have studied the effect of the cleaning process on the color and the homogeneity of the samples using a hyperspectral imaging workflow. Four different analysis methods are presented and discussed. Our results show that the proposed analysis is able to provide a much more comprehensive and diversified characterization of the quality of the cleaning method compared to the commonly used colorimetric or photometric area-based measurements.

Representation Of Knowledge

Sak Yan Ontology (SYO) models knowledge derived from Thai tattoos in the design of cultural heritage preservation planning. Ontology Development 101 is a technique of ontology model creation. The aims of this study are to share the performance of ontology development and ontology evaluation. The study is specifically focused on validation from domain experts and automation evaluated using the OOPS! tools (OntOlogy Pitfall Scanner is a tool that helps detect some of the most common pitfalls appearing when developing ontologies). The results obtained from OOPS! show that SYO is devoid of critical errors; however, it does have one critical, three important, and three minor problems. Four of the problems are fixed, whereas the others are continuous. The combination of automatic and human validation methodologies improves the quality of the ontology being modeled. The tools enhance the traditional methodology with quicker, easier, and smaller amounts of subjective analysis. In conclusion, for the reparation movement, solutions for the above problems are suggested.

Light causes damage when it is absorbed by sensitive artwork, such as oil paintings. However, light is needed to initiate vision and display artwork. The dilemma between visibility and damage, coupled with the inverse relationship between color quality and energy efficiency, poses a challenge for curators, conservators, and lighting designers in identifying optimal light sources. Multi-primary LEDs can provide great flexibility in terms of color quality, damage reduction, and energy efficiency for artwork illumination. However, there are no established metrics that quantify the output variability or highlight the trade-offs between different metrics. Here, various metrics related to museum lighting (damage, the color quality of paintings, illuminance, luminous efficacy of radiation) are analyzed using a voxelated 3-D volume. The continuous data in each dimension of the 3-D volume are converted to discrete data by identifying a significant minimum value (unit voxel). Resulting discretized 3-D volumes display the trade-offs between selected measures. It is possible to quantify the volume of the graph by summing unique voxels, which enables comparison of the performance of different light sources. The proposed representation model can be used for individual pigments or paintings with numerous pigments. The proposed method can be the foundation of a damage appearance model (DAM).

History Of

AbstractIn the summer of 1828, the Entreprise générale des Dames Blanches launched a fleet of white omnibuses onto the streets of Paris. These public transportation vehicles were named and fashioned after Boieldieu's opéra comique La dame blanche (1825): their rear doors were decorated with scenes of Scotland, their flanks painted with gesturing opera characters, and their mechanical horns trumpeted fanfares through the streets. The omnibuses offered one of the first mass transportation systems in the world and were an innovation that transformed urban circulation. During their thirty years of circulation, the omnibuses also had a profound effect on the reception history of Boieldieu's opera. When the omnibuses improved the quality of working- and middle-class life, bourgeois Parisians applauded the vehicles’ egalitarian business model, and Boieldieu's opera became unexpectedly entwined in the populist rhetoric surrounding the omnibus. Viewing opera through the lens of the Dames Blanches, Parisians conflated the sounds of opera and street, as demonstrated by Charles Valentin Alkan's piano piece Les omnibus, Op. 2 (1829), which combines operatic idioms and horn calls. Through these examples and others, this study examines the complex ways that material culture affects the dissemination and reception of a musical work.

The Impact

The study aimed to evaluate the effects of process parameters (time and raw material weight (RMW)) of conventional (boiling for 10–45 min) and microwave-assisted (2–8 min) aqueous extraction on the color quality (i.e., lightness (L*), chroma (C*), and hue (H°) of anthocyanin –based colorants of red and Inubi sweet potato (Ipomoea batatas L.) leaves. Using response surface methodology, it was found that RMW and boiling time (BT) and microwave time (MT) generally had a significant (p < 0.05) effect on the color quality of the extract from both extraction methods. The effects were found to vary depending on the extraction method and variety of the leaves used. Both extraction methods produced a brown to brick-red extract from the Inubi variety that turned red-violet to pink when acidified. The red sweet potato leaves produced a deep violet colored extract that also turned red-violet when acidified. It is recommended that the anthocyanin content of the extracts be measured to validate the impact of the methods on the active agent. Nevertheless, the outcomes in this study may serve as baseline data for further studies on the potential of sweet potato leaf colorants (SPLC) as a colorant with functional properties.
