The guidelines presented in this document are a preliminary strategy for establishing a comprehensive policy for the needs of training and education wiyhin the sector and adjoining areas, across fields of knowledge and professions concerned, on relevant levels and for the varies institutions and operators. The objective of these guidelines is to analysis the problems, objectives and goals for development of a far reaching system of educational and training programs and courses for museums, cultural heritage and related fields of activities. This objective comprises a close collaboration between museum, cultural heritage organizations and educating organizations, notably within universities and colleges, but also other kinds of educating bodies.

The authors present a review of the advances that have been made to establish terahertz applications in the cultural heritage conservation sector over the last several years. This includes material spectroscopy, 2D and 3D imaging and tomographic studies, using a broad range of terahertz sources demonstrating the breadth and application of this burgeoning community.

Terahertz pulse imaging (TPI) is a novel noncontact, nondestructive technique for the examination of cultural heritage artifacts. It has the advantage of broadband spectral range, time-of-flight depth resolution, and penetration through optically opaque materials. Fiber-coupled, portable, time-domain terahertz systems have enabled this technique to move out of the laboratory and into the field. Much like the rings of a tree, stratified architectural materials give the chronology of their environmental and aesthetic history. This work concentrates on laboratory models of stratified mosaics and fresco paintings, specimens extracted from a neolithic excavation site in Catalhoyuk, Turkey, and specimens measured at the medieval Eglise de Saint Jean-Baptiste in Vif, France. Preparatory spectroscopic studies of various composite materials, including lime, gypsum and clay plasters are presented to enhance the interpretation of results and with the intent to aid future computer simulations of the TPI of stratified architectural material. The breadth of the sample range is a demonstration of the cultural demand and public interest in the life history of buildings. The results are an illustration of the potential role of TPI in providing both a chronological history of buildings and in the visualization of obscured wall paintings and mosaics.

Techniques to retrieve reliable images from complicated objects are described, overcoming problems introduced by uneven surfaces, giving enhanced depth resolution and improving image contrast. The techniques are illustrated with application to THz imaging of concealed wall paintings.

The aim of this paper is to give an overview of the issues and actions on the Brazilian cultural heritage and then to discuss contributions as well as relationships that may be established from the principles of Information Science. The first item is concerned with the relationship between heritage and the concept of document, the second relates the documentary processes and the information scientist and finally, an approach of cultural heritage mediation and appropriation is presented.

This article investigates aspects of the production, dissemination and consumption of UNESCO’s first international touring exhibition, Australian Aboriginal Culture, in order to explore the relationship between UNESCO and Australia in the development of a key cultural heritage program. It argues that the exhibition indicates a national and international spirit of universalism that attempted to address crosscultural ignorance in a period of post-war optimism.

UNESCO's Convention for the Safeguarding of Intangible Heritage came into force in April 2006, signalling a major expansion of the global system of heritage protection from the tangible to the intangible. It is an expansion that some heritage professionals see as opening up a Pandora's box of confusions and complexities. The conservation of inanimate objects tangible sites and monuments and artefacts - is difficult enough; but the protection of heritage embodied in people raises new sets of ethical and practical issues. The paper canvasses these concerns and focuses on how the notion of human rights must be used as a way of limiting and shaping the Intangible List. In particular it outlines the ways in which the protection and preservation of cultural heritage is linked to 'cultural rights' as a form of human rights. This linkage is not clearly recognised by cultural heritage practitioners in many countries, who view their work merely as technical, or even by human rights workers, despite the abundance of opportunities around the world to witness people struggling to assert their cultural rights in order to protect their heritage and identity.
