This paper presents preliminary results from experimental u-learning solutions designed to blend different paradigms and technologies, including cloud services. The technical objective was to evaluate the most cost-effective technological solutions for a remote and isolated rural community, having non-permanent internet connection and scarce financial resources. The learning objective was to provide a rural school community with ubiquitous access to knowledge related to forgotten traditional crafts. The educational content was designed by a group of professors and technicians from National University of Arts (NUA) Bucharest. The experiments have been supported by and undertaken within the research grant PN II - 'Maps of Time'. The paper presents key technical aspects of the solutions, a preliminary evaluation after a 6 month experimentation of the solution with a target group comprising 10 children and 4 school teachers, and also a perspective over the future work. © 2013 IEEE.

In the present paper, an analytical characterization of mural painting samples coming from a 14th century Romanian Monastery has been carried. Investigations were performed through non-destructive spectroscopic techniques: X-Ray Fluorescence (XRF) using a handheld energy-dispersive XRF analyzer and Fourier Transform Infrared Spectroscopy (FT-IR) in Attenuated Total Reflectance (ATR) geometry. Results obtained via XRF, corroborated with FTIR data, permitted a complete material characterization in terms of elemental composition and molecular structure. A series of mineral pigments were identified - green earth, azurite, cinnabar, lead white, zinc white, ochre, emerald green; as well as the presence in some of the analyzed areas of organic binders such as vegetable wax or linseed oil. Previous restoration interventions were also evidenced as identification of one pigment respect to another, or via the presence of barium sulfate that we assume as coming from a filler, barium sulfate being often used in the chemical formulation of modern painting materials. © 2015 IEEE.

Radiation Physics and Chemistry | Year: 2012

The degradation of cultural heritage objects by insects and microorganisms is an important issue for conservators, art specialists and humankind in general. Gamma irradiation is an efficient method of polychrome wooden artifacts disinfestation. Color changes and other modifications in the physical chemical properties of materials induced by gamma irradiation are feared by cultural heritage responsible committees and they have to be evaluated objectively and precisely. In this paper FTIR and FT-Raman spectroscopy methods were used to investigate the structural changes in some experimental models of tempera paint layers on wood following 11. kGy gamma irradiation at two dose rates. Radiation chemistry depends on the particular pigment, matrix formed by protein, resin (in case of varnished samples) and water presence. For the majority of painted layer in experimental models very small spectral variations were observed. Small changes in the FTIR spectra were observed for the raw sienna experimental model: for the higher dose rate the egg yolk protein oxidation peaks and the CH stretching bands due to lipids degradation products increased. © 2011 Elsevier Ltd.

The present report is related to a running project on contemporary visual art conservation and is considering various case studies, involving different techniques. On one hand the research investigates by means of advanced optoelectronical methods a series of modern artworks, while on another approach is testing today's art materials stability by undergoing accelerated ageing. The multiannual research's main aim is to create a new scientific approach in contemporary visual art and start up an advance form of specialization in restoration/conservation based on rigorous organized information about new materials and techniques, all with full and deep respect for contemporary artists and their artwork. The general objective is absolutely thought not to constrain the artists' practice, but to inform them and to create necessary set-ups and comprehensive databases, as decisive information for the restorers' community of tomorrow.

The difficult path of e-learning in vocational schools, mainly professor - student oriented, pushed a few researchers from the music and visual fields to build a new opinion through the student last trends: if the vocational study cannot be entirely based on e- learning technologies, there could be the mobile learning environments and the real world experiences transmitted to students from all over the world, interested in graduating different kind of courses from different higher education colleges, unified by a new legislation, at least in the European Union. The technical demonstrations made by great masters in their own studios, with the help of a few teachers and students, give the possibility to follow step by step different kind of performing arts from music to visual arts, and to present the results through Internet servers to other remote european schools. The need to cooperate between european higher education schools through common projects fulfill the need of communication between students, teachers and peoples of different countries. © 2011 IEEE.
