The frieze of the Palace of the stuccoes, dated between the 5 th and 6 th century BC, was a polychrome Maya relief discovered in the 1907 in Yucatán, Mexico. It was documented in watercolours and hand tinted photographs by Adela Breton. After years of exposure to the harsh environmental conditions of the Maya area, the colours and the stucco relief disappeared. The aim of the project is to develop a hybrid digital-analogue printing method for reconstructing the appearance of the original polychrome relief based on digitised hand-made records.<br/> A description of the process to produce full colour images combining digital and photomechanical printing is provided. Using photopolymer plates, an intaglio printing process has been used to produce colour images, whilst inverse relief plates have been created based on height maps to transfer a positive embossing on paper when applying pressure on a printing press. The influence of physical parameters related to the appearance is studied. Reflectance Transformation Imaging was carried out to record the colour and surface shape of the prints. Measurements of gloss were made on relief inkjet prints and intaglio prints on paper to compare the outcomes of commercial 2.5D print and the method proposed here.<br/> By modifying an analogue process with digital technology, it is possible to incorporate ancient materials to the printmaking process and therefore approach naturally the appearance of the original. On the other hand, incorporating imaging techniques and quality measurements enables to improve the quality in analogue printing techniques.

Abstract The purpose of this article is to provide clinical supervisors with information pertaining to state-of-the-art clinic observation technology. We use a novel video-capture technology, the Landro Play Analyzer, to supervise clinical sessions as well as to train students to improve their clinical skills. We can observe four clinical sessions simultaneously from a central observation center. In addition, speech samples can be analyzed in real-time; saved on a CD, DVD, or flash/jump drive; viewed in slow motion; paused; and analyzed with Microsoft Excel. Procedures for applying the technology for clinical training and supervision will be discussed.

It is argued that the digital technology has made possible the vast range of applications and media forms including virtual reality, digital special effects, digital film, digital television, electronic music, computer games, multimedia, the Internet, the World Wide Web, digital telephony and so on [8]. Digital transformation has been particularly influential in new directions of society.Providing schools with digital technology promises a high return on investment. The presence of computers and Internet access raises technology literacy and skills, better preparing the future generations to participate in the information society [12]. To this end, schools represent ideal access points because they cover a large part of the population, especially in developing countries. Starting from 1990s, many educators have been realised the potential of Internet for educational purposes and began to introduce it into classrooms. According to [10] the popularity of web-based teaching and learning lies in the strengths of its distributed nature and the case of its browsing facility. Both the use of digital technology and increased interest in student-centered learning may lead to a significant change of the teacher’s role, as well as the recognition of the active role of the learner in the learning process.

This study explores the use of a new protocol in hypertension care, in which continuous patient-generated data reported through digital technology are presented in graphical form and discussed in follow-up consultations with nurses. This protocol is part of an infrastructure design project in which patients and medical professionals are co-designers. The approach used for the study was interaction analysis, which rendered possible detailed in situ examination of local variations in how nurses relate to the protocol. The findings show three distinct engagements: (1) teasing out an average blood pressure, (2) working around the protocol and graph data and (3) delivering an analysis. It was discovered that the graphical representations structured the consultations to a great extent, and that nurses mostly referred to graphs that showed blood pressure values, which is a measurement central to the medical discourse of hypertension. However, it was also found that analysis of the data alone was not sufficient to engage patients: nurses' invisible and inclusion work through eliciting patients' narratives played an important role here. A conclusion of the study is that nurses and patients both need to be more thoroughly introduced to using protocols based on graphs for more productive consultations to be established.
