The paper discusses the use of 3D online virtual museums as educational instruments for children in economically disadvantaged communities. It discusses the advantages of simulation and immersion as learning enhancements, compared to traditional learning methods, using a case study based on the currently on-going work of development of a virtual museum ( page-id=6). Presenting chronologically layered information, the museum offers a series of e-learning modules teaching traditional crafts technologies. The current audience is represented by children from a Romanian village community. The paper covers a description of the methodology used, as well as an evaluation of the usefulness of the solution by the target audience. In conclusion, the paper outlines a strategy for further development of the proposed e-learning solution.

In this paper, chemical and physical nature of the metal threads surfaces and their silk core yarns used in the Romanian religious embroideries and velvet brocades, dating from 15th to 16th century, have been investigated by using the Attenuated Total Reflectance/Fourier Transform Infrared Spectroscopy (ATR/FTIR). Results obtained may help decoding the history of some of the most valuable medieval metal thread textiles preserved in the Romanian museums and monasteries collections, and advancing diagnostic techniques for choosing appropriate conservation and restoration treatments and efficient monitoring of the deterioration processes.

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.

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.

During the last century technological progress has begun to reveal its faults. Industry has brought many benefits to humanity but negative repercussions are becoming apparent, particularly where ethical issues are concerned. As a fiber artist and textile designer I seek to revitalize traditional solutions like manual weaving, manual printing and plant dyeing technologies. This direction in contemporary art is a reaction that has gathered together not only artists but a group of people interested in the importance of traditional patterns of sustainability, like ethnologists, anthropologists, art critics and economists. Artists cannot limit themselves to raising questions; their artworks have to make a statement towards change, otherwise they just perpetuate a society in which aesthetics is just another word for beautiful waste. It is important to revitalize green technologies and implement solutions that have been tested throughout the ages; the ritual gestures that strengthen links between humans, their artifacts and the environment. © 2013 Taylor & Francis Group.

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.

The monastery church of Curtea de Arge° was not so far examined from the perspective of symbolic meanings of its architectural structure, on which the old descriptions drew attention particularly on several occasions. The present study examines these textual descriptions both of the architecture and of the iconographic program of the paintings and draws some conclusions on the general theological ideas that stood at the basis of this monument. The church is the place where Holy Trinity is dwelling and in which the twelve Apostles have a central place, as the columns which support the Church, symbols of an early Christian origin, also found at the basilicas built by Emperor Constantine in Jerusalem (i.e. Eleona and Holy Sepulchre) and conserved in the Armenian rite of consecrating church foundations. Saints and Holy Fathers also have a main place in the spiritual architecture of the Church, signified by the 318 lilly-shaped stone elements of the balustrade that existed around the catholicon. An interesting allusion to the Psalm 84 was found in the number of the stone discs on the façade, decorated with 84 gilded birds. In the 'house of Holy Trinity' at Argeş it is reiterated symbolically the apostolic confession of Faith. Within, among saints, the Wallachian Princes were portrayed in the votive paintings, as new keepers of the Orthodoxy.

There are very little variations in the evolution of portraits' functions on the entire length of over eleven centuries of Byzantine art and the four more of post-Byzantine. Basically, they accomplish a documentary role: they are used on legal acts, on votive objects or accompany funeral tombs. Rulers' portraits were seen as efficient symbols of the institution of monarchy, in which case were used on coins, legal acts and seals, as a guarantee of authenticity and legal effectiveness. Emperor's portrait had, in some situations, the status of replacing the real presence of the monarch, e.g. in courtrooms, or sent to vassal princes in diplomatic purposes, to replace symbolically the visit of the sovereign. Imperial representations in mural paintings were generally accomplished in votive or commemorative purposes. Their images illustrated the religious concept of the nature of monarchy: the divine origin of power. Their role, in this case, was of moral antidotes against the corruption of political power. Not the monarch prescribed the spiritual functions and themes of his portraits, but he was the one to whom they were prescribed, by intellectuals and theologians, through the artists.

There is a growing body of literature that recognizes the importance of the 3D multi-user virtual environments (3DMUVEs) with high relevance for prospective developments and improvements in both distant and in-class education. However, to be accepted on a larger scale by education practitioners more analitical studies are required to evaluate these environments against usability and pedagogical effectiveness criteria. The present paper proposes an automatic in-world monitoring system consisting in scripted tracking objects and Learning Analytics (LA) tools for an experimental 3D virtual campus. The research was conducted within a transversal study using focus groups from two universities, an engineering and a vocational one. The results highlighted the validity of the automated system and LA tools, which can constitute the ground for more efficient teaching and learning in complex activity-based 3D educational settings. © 2016, Italian e-Learning Association.
