In the light of the recent concerns in the assessment of the new conservation treatments and of the development and application of methodologies, technologies, models and tools for CH damage assessment, this paper will deal with some innovative topics related to the digital models for protecting cultural heritage assets in front of various damages. Application of new technologies and digitalization of Basarabi monument is a preventive measure, helping us to build a virtual reconstructions as model for its potential reconstruction and preserving, to give access for the widest possible audience. It will be discussed the new technologies, as the non-destructive diagnosis technologies for the safe conservation a this historic, cultural and architectural – Basarabi churches. For the micro-climatic measurements, a number of sensors have been well distributed inside and outside and a diagram of humidity an temperature is evaluated. The practical examples of restoration and preservation and innovative solutions for the consolidation of this architectural monument, in relation with digitalization (by on-site and remotely data collection, virtual reality and documentation of the heritage). For a digital image of this monument, both a 3D laser scanner and some common digital photos are used, in order to obtain the 3D model of the church, and of the envelope of the church that should be applied over it to stop the seriously damage processes.

In this context, the analysis of integrating service usability is essential and gives new directions for functionality extension and improvement. This paper presents an analysis of the usage of the interoperability service, compiling content from two digital libraries for Orthodox art and knowledge – the Encyclopaedia Slavica Sanctorum and the Bulgarian Iconographical Digital Library.

Optimization of Natural Dyes' Non-contact Characterization and Interdisciplinary Application Using Ensemble Classifiers and Genetic Algorithms

Author(s): Magdelena Stoyanova,Detelin Luchev,Desislava Paneva-Marinova / Language(s): English Issue: VI/2016

The reported evaluation of the problematic encountered by non-contact characterization of natural dyestuffs demonstrates that practically no one analytical method alone – destructive, less, or non – can warrant absolute reliability of the results. The main obstacles are due, in general, to our limited knowledge on reactivity of natural compounds, their sources, methods of proceeding and application; to the complexing role of the ambient/medium on the photo reactions, as well as to the actual possibilities of analytical techniques; to the lack of commonly accepted standards amongst different scientific traditions, etc. For to overwhelm these drawbacks and optimize accuracy of NDs characterization, we propose the integration of chemio-physical with computational assessment. The proposed approach consists in calculation the probability of a hypothesis comparing new results with already stored interdisciplinary data using the high performance ensemble techniques Random Forest and Random Subspace based on the genetic approach termed EV-Ensemble approach. Its role is to render more accurate the analytical results, to avoid sampling and simplify the identification analysis, to facilitate interdisciplinary applications of NDs in high technologies, and to share generated experience between the research community.

Endangered Photo Collections about the Participation of Pre-industrial Bulgaria in Three Wars in the Beginning of the 20th Century

Author(s): Valeri Katzounov / Language(s): English Issue: VI/2016

The resources of the modern technology presuppose an initiative development in order to unite the efforts and activities for the collaboration in digitalization of the most important pieces of cultural and historical heritage. In a number of cases they have received the support of scientific projects for the creation of an open communication environment with a purpose of promoting the cultural values of the community. This report presents work on a research project for the conservation of cultural heritage at risk. The problem is with national priority and occupies a significant place in the European integration process. The two collections with which we apply in the British Library need special attention due to their poor structural condition even at the time of their transfer to the Bulgarian Academy of Sciences more than 50 years ago. The first collection was created by Colonel Petar Darvingov and consists of 3100 black and white old photos, maps and sketches. The second collection of Aleksandar Bozhinov contains 2050 old photos, sketches, caricatures and cartoons with pencil and ink. The documents have an exceptional historical and informational value, but their physical conditions hinders their scientific use. The creation of digital copies will enable working with them, which in turn will protect the originals from further damage. The copied documents will build a distinct insurance fund and the institution will be able to broadcast scientific information through various forms of promotion of the fund – exhibitions, presentations, etc.

O niektórych strategiach otwarcia na czytelnika w wybranych przykładach literatury nowomedialnej (rekonesans)

Author(s): Agnieszka Przybyszewska / Language(s): Polish Issue: 1/2016

This article looks at selected examples of e-literature and related fields to explore strategies of creating communicative openness towards the reader. Przybyszewska focuses on two different approaches: the text’s programmed playability, which results in the work’s performative nature, and strategies of including readers’ actions or gestures (most often gestures that overlap with in the imagined universe) within the sphere of the work. This inclusion conditions the reader’s ongoing discovery of the story, or it even influences the work itself. These devices strategically open text to the reader (which mirrors expectations in cultures of participation); they help strengthen the literary mechanisms of immersion or projection-identification, and finally, they facilitate the audience’s entry into the imagined universe and they highlight specific literary values.

Author(s): Lucija Vejmelka,Nives Strabić,Marija Jazvo / Language(s): Croatian Issue: 1/2017

Internet addiction and cyberbullying among youth are phenomena that show a significant increase owing to the development of technology and the wide accessibility of the Internet. Research was conducted among adolescents (N = 352) in 9 randomly selected high schools in Croatia, with the aim of investigating the relationship between habitual Internet use and online risk behaviors among adolescents. The standardized measuring instruments used in the research were the Internet addiction test (Young, 1998) and The European Cyberbullying Intervention Project Questionnaire (Del Rey et al., 2015) and questions about sociodemographic characteristics of respondents and online activities. The results show that 36.2% of the participants exhibit different symptoms of Internet addiction, while 50.7% of them partake in various forms of cyberbullying. Furthermore, it is established that the amount of time spent on the Internet on instant messaging, watching movies/videos, listening to music and playing online games correlates both with Internet addiction and with participating in cyberbullying among young people. The research confirmed the assumptions of the theory of routine activities and the results indicate that perpetrators of cyberbullying show a tendency to risky behavior also in other online activities. The paper presents the relationship between the level of Internet addiction and experience of cyberbullying and provides guidelines for future research in this area.

Digital Object Identifier (DOI) – an Important Element in Scientific Communication

Author(s): Еlena Pavlovska / Language(s): English Issue: VII/2017

Digital object identifier (DOI), which appeared in the late 1990s, allows users to immediately find on the Internet the digital object they are interested in – an article, book, journal, dissertation, etc. Nowadays the DOI technology is widely used by foreign publishers. The availability of DOI in scientific documents, as well as the inclusion of DOI in bibliographic references in the literature, has already become a mandatory requirement for journals indexed in the Web of Science and Scopus databases. Unfortunately, DOI is included only by some journals published in Bulgaria. The article presents some new opportunities which DOI opens not only to scientific journals, but also to authors.

Deep Belief Networks for Multimodal, Images-based Non Contact Material Characterization

Author(s): Magdelena Stoyanova,Lilia Pavlova / Language(s): English Issue: VII/2017

Our growing cognisance about the chemo-physical properties of electromagnetic waves and of their interaction with various materials provides expanding range of possibilities for quantification and non contact material characterization even in difficult to computation, « non-standard » domains as this of the cultural heritage. This review - thematically part of the IFIDA project dedicated to digitization of archaeometric and conservation-restoration praxis - deals with the possibilities latest neuroinformatic methods offer for a more efficient and fast interrogation, understanding and classification of multi-modal spectral records of paintings on various supports. The workflow followed during their routine non destructive (ND) analysis by human experts is described in terms of specific technical characteristics, research objectives and concrete application for the artworks' characterization as a prototype to simulate artificially. References to techniques for high semantic level information extraction from low-level features are suggested. The strengths and limitations in application of Deep Belief Networks (DBNs) for compression, visualization and data recognition are also considered. Examples of most appropriate architectures and topological maps of Deep Learning Networks for interpretation of UV, IR, XR, β, γ and CT records performing simple characterization and classification tasks - from single layer perceptron to multi-layer deep belief neural networks for unlabelled data - are presented and explained.
