THE GEO-REFERENCED XIX CENTURY CARTOGRAPHY: AN ANALYSIS TOOL AND A PROJECT REFERENCE FOR THE PRESERVATION AND MANAGEMENT OF BUILT AND LANDSCAPE HERITAGE
Authors: Cazzani A. , Brumana R. , Zerbi C. M.
Published: May 2019

Abstract. Considering built and landscape heritage, the paper demonstrates how it is necessary to conserve the historic stratification and to define new compatible plans and uses, identifying the ways to mitigate alteration impacts, requalify degraded areas, enhance natural, historic and cultural values, improve documentary and educational options, and manage new tasks and opportunities. Particularly, the historic complexity of built and landscape heritage, and the level of permanence can be recognized and evaluated by comparing multi-temporal historic and current maps, and surveying the present situation in order to define preservation strategies.Innovative tools (open source map registry, open source GIS data management) support the critical analysis of the maps, the representation of historic stratification, the evaluation of conservation levels, and the definition of heritage reuse and management. Moreover, innovative applications based on advanced Virtual Hub, when used to publish historical maps as Open Data (GEOPAN ATL@S APP), allow a larger public of non-expert users (tourists, citizens, bikers, students, etc.) to access the extraordinary richness of the historical map contents, and navigate across urban landscapes. Such APPs are thus becoming instruments of awareness with a strong pro-active capacity to stimulate new design plans encompassing local cultural identity and rediscovering traces of the past.
BENCHMARK OF METRIC QUALITY ASSESSMENT IN PHOTOGRAMMETRIC RECONSTRUCTION FOR HISTORICAL FILM FOOTAGE
Authors: Condorelli F. , Rinaudo F.
Published: May 2019

Abstract. Quality assessment in photogrammetric processing is fundamental to obtain metric information and to reconstruct 3D models of Cultural Heritage, especially when it has been lost or changed over time. The determination of metric precision is technically challenging when dealing with historical films and videos that in many cases represent the only remaining traces of this heritage, which is useful for architectural, archaeological and restoration studies. This paper examines the suitability of existing photogrammetric software to evaluate the maximum possible metric accuracy for processing videos shot with fixed camera motions. In order to evaluate the metric quality obtained processing historical film footage with photogrammetric techniques, a benchmark was created on a new video dataset with the aim of reproducing the camera motions in which old video were shot. Three different camera motions were considered: Up/Down Motion-Tilting, Left/Right Motion-Trucking and Rolling Motion-Panning. The methodology was experimented on Valentino Castle in Turin, a monument inscribed in the UNESCO World Heritage List. Data were processed with the implementation of open source Structure-from-Motion algorithms and the results were analysed for the evaluation of metric quality. Results show the different maximum precision assessments according to the different typologies of camera motion. This research provides fundamental support to historical studies on Cultural Heritage, creating a sharing standard with zero-cost data and tools useful for both geomatics and restorers.

Published: May 2019

Abstract. This paper presents some of the results obtained from the integrated use of 3D surveying techniques and illustrates some types of analysis and graphic representations that can be conducted and reproduced. The case study concerns the church of San Nicola in Montedoro that is one of the oldest in the city of Martina Franca in the province of Taranto (Italy) and presumably dates back to the fourteenth century. The work consists of a survey with different integrated methodologies, the creation of thematic tables all in order to allow a structural analysis.The contribution shows how this approach is not intended for a single case study, but starting from it can be extended to other contexts that present similar criticality and potential, often recurrent in the field of the survey and representation of cultural heritage.
A WORKFLOW FOR GEOMETRIC COLOUR PHOTOGRAPHY OF PAINTED SURFACES
Authors: Dhanda A. , Scarpa G. , Fai S. , Santana Quintero M.
Published: May 2019

Abstract. Colour fidelity is vital when documenting painted surfaces. The 2.5D nature of many painted surfaces makes orthophotos and digital surface models (DSMs) common products of the documentation process. This paper presents a workflow to combine photographic and photogrammetric methods to produce aligned colour and depth (orthophotos and DSMs). First, two photogrammetric software (Agisoft Photoscan and Capturing Reality Reality Capture) were tested to determine if they adjusted the colour data during the processing stages. It was found that Photoscan can produce 16-bit orthophotos without manipulating the data; however, Reality Capture is currently limited to 8-bit results. When capturing a surface using photogrammetry, it is common to use the same data for colour and depth. The presented workflow, however, argues that better colour accuracy can be achieved by capturing the two datasets separately and combining them in photogrammetric software. The workflow is demonstrated through the documentation of an unnamed religious painting from the 17th century.
REPRESENTATION AND DIGITALIZATION OF STONE THEATRES IN EASTERN SICILY: THE PALAZZOLO ACREIDE THEATER
Authors: Di Gregorio G.
Published: May 2019

Abstract. The ancient theatres in Sicily, in southern Italy and along the countries facing the Mediterranean Sea basin, constitute a reality of incomparable cultural value. Regarding the research on the ancient theatres of eastern Sicily, few studies have been recently dealt with different methodologies. In the last years some practices have been done using 3D laser scanners for the theatres of Syracuse, Taormina and Morgantina, as well as the Syracuse amphitheatre and Taormina Odeon, just obtaining very interesting results. Lately the theatre of Palazzolo Acreide (Syracuse) has been studied, with Structure From Motion (SFM) and Dense Matching methodologies. From these experience, conclusions could be drawn on the quality and reliability of the elaborations realised with the SFM methodologies. We really know that these systems are today representing one of the fastest growing areas of examination, on which several software houses are investing. The study was chosen both for the small size of the building, and for the particular geometric conditions typical of the architecture of ancient theatres. This because their three-dimensional trend varies continually in the three variables X, Y, Z. The purpose of the work was to check whether the latest releases of these systems of survey allow today more than yesterday, a rapid digitalization and representation of the enormous archaeological cultural heritage. Various software were used, to verify the practicality and operation, the choice then fell on the Zephyr of 3DFlow, kindly available by the manufacturer, whose results were quite agreeable. The possibility offered by the program of a graphical tracing of polylines on the textured 3D model, has been a considerable advantage. Therefore the results obtained by modeling and surveying of the Palazzolo Acreide theatre have been compared, with the survey of the Syracuse, Taormina and Morgantina theatre performed using 3D laser scanners. First results of the research are matter of the following work.
SCAN PLANNING OPTIMIZATION FOR OUTDOOR ARCHAEOLOGICAL SITES
Authors: Díaz-Vilariño L. , Frías E. , Previtali M. , Scaioni M. , Balado J.
Published: May 2019

Abstract. The protection and management of archaeological sites require from a deep documentation and analysis, and although hand measuring and documentation is the cheapest way for collecting data, laser scanner has been gradually integrated for the geometrical data capture since point clouds have a high quality in terms of accuracy, precision and resolution. Although acquisition with laser scanner is considered a quick process, scan planning is of high relevance when considering outdoor archaeological sites because of their large size and complexity. In this paper, an automatic methodology to optimize the number and position of scans in order to obtain a point cloud of high quality in terms of data completeness is proposed. The aim of the methodology is to minimize the number of scans, minimizing at the same time the estimated surveying time and the amount of repetitive acquired data. Scan candidates are generated by using a grid-based and a triangulation-based distribution, and results show a faster analysis when triangulation is implemented. The methodology is tested into two real case studies from Italy and Spain, showing the applicability of scan planning in archaeological sites.
KEYNOTE: THE BIOGRAPHY OF OBJECTS
Authors: Greco C.
Published: May 2019

Abstract. Today we find ourselves immersed in what is called the digital revolution, which has already profoundly transformed our cognitive approach and working methods. In archaeology, photogrammetry and 3D modelling enable archaeologists to document the whole excavation process and reconstruct contexts even after they have been removed. We can reproduce a coffin with sub-millimetric accuracy by recording all its phases of production and reuse. Non-invasive diagnostic imaging enables us to peer inside a still sealed vessel and virtually unwrap the mummies. Accurate analysis now gives scholars the opportunity to observe the fibres of a papyrus, helping us recompose ancient documents. Then digital communication enables us to create virtual working environments in which scholars from all over the world can confer and compare their data. All this facilitates and accelerates the work of scholars.Does this mean that the humanist's role is becoming secondary? Quite the contrary. The data we glean is increasingly detailed and complex and requires an even greater level of interpretation. The scientist and the humanist have to work together even more closely to try and unravel the complexity of the contemporary world. This increasing collaboration goes beyond the dogmatisms of individual knowledge. The definition of a shared semantics and the development of a true multidisciplinary approach are the only method we have to cope with the challenges of the future.And in all this, what will the role of the museum be? Are these institutions destined to disappear? The changes will continue. We will think of different organisational and architectural solutions responding to contemporary needs. There will certainly also be new forms of cultural enjoyment. Our task, however, will always be to improve the visual, aesthetic and intellectual experience of every visitor who comes face to face with a piece of the past, and to provide all the information necessary to enrich their understanding. So the future of museums is, as it has always been, research.
DISCOVERING AND COMMUNICATING THE RATIONALIST ARCHITECTURE OF FORLÌ. AN INTEGRATED PROCESS
Authors: Favaretto G. , Pretelli M. , Zampini A.
Published: May 2019

Abstract. A partnership between the Department of Architecture of the University of Bologna and ATRIUM aimed at enhancing the knowledge and communication of the rationalist architecture, built in the city of Forlì during the Fascist regime. The importance of finding an interpretative key for this dissonant heritage, bearers of an “uncomfortable” memory but at the same time able to strongly characterize the architectural quality of cities, was a primary goal.The cooperation started with the development of a pilot project regarding three architectures considered iconic for this context but also able to foster more complex urban policies. The first deliverable of the programme was the search, record, and management of the archival materials related to the whole history of these buildings. The enormous amount of data acquired revealed the importance of working on a dual track, aimed at both the stakeholders involved in the management process of this heritage and those who experience it.For what concerns the “technical level” which is related to the knowledge field, the first challenge was to understand how to manage information boosting interoperability, guaranteeing easy access and above all making the research implementable. According to the “touristic level” instead, a further objective of the project was related to the communication of this heritage to a varied audience of visitors.
GEOMATICS AND ARCHAEOMETRIC INVESTIGATIONS FOR THE SUSTAINABLE REUSE OF RUINS. THE SANTA CHIARA CONVENT RUIN IN CAGLIARI (SARDINIA)
Authors: Fiorino D. R. , Grillo S. M. , Pilia E. , Vacca G.
Published: May 2019

Abstract. The ruined convent of Santa Chiara, a nodal urban space connecting three historic quarters of Cagliari, has had a key role in the urban life of the city since medieval age. After the suppression of the mendicant orders in 1864 and the violent bombings during the World War II, this monument become a neglected and ruined shell of masonry with no roofs and floors, losing its central role. Several interventions for its conversion as temporal local market and the following restoration and integration works have contributed to stratify these structures nowadays not accessible but valuable benchmarks for reconstructing the history and evolution of the fabric, still unclear. Starting from the archival and bibliographic investigations, then a geomatics and archaeometric investigations of the fabric have allowed to understand and study the building’s forms, geometries, materials, developments, and chronologies. They have also permitted to recognise characteristic features or anomalies, structural morphology, and other structural issues, significant for the definition of sustainable project of reuse.
EVALUATING SMARTPHONES COLOR FIDELITY AND METRIC ACCURACY FOR THE 3D DOCUMENTATION OF SMALL ARTIFACTS
Authors: Gaiani M. , Apollonio F. I. , Fantini F.
Published: May 2019

Abstract. Smartphone camera technology has made significant improvements of sensors quality and software camera performance in recent years. Devices as Apple iPhone X and the Samsung Galaxy S9 Plus, allow to reach levels of image resolution, sharpness and color accuracy very close to prosumer SLR cameras, enabling also on-the-fly processing and procedures which were considered impossible to achieve until a few years ago. Starting from these premises, a series of issues and opportunities concerning smartphone application to artifacts documentation will be discussed. In particular, consistency and reliability of both shape and color representation achievable for small-medium artifacts belonging to exhibitions and museum collections. A low-cost, easy-to-use workflow based on low-cost widespread devices will be compared to consolidated digitization pipelines. The contribution focus is based on color accuracy of textured models achievable through smartphones by means of an internally developed application for the achievement of highly reliable developments of raw formats (.DNG) from Apple iPhone X. Color consistency will be calculated in terms of the mean camera chroma relative to the mean ideal chroma in the CIE color metric (ΔE*00) as defined in 2000 by the CIE on the CIEXYZ chromaticity diagram.
INTEGRATED STUDY OF THE BEATA VERGINE ASSUNTA DOME WITH STRUCTURE FROM MOTION AND DIAGNOSTIC APPROACHES
Authors: Grillo S. M. , Pilia E. , Vacca G.
Published: May 2019

Abstract. Between 1839 and 1849, the architect Gaetano Cima built a very interesting neoclassical church with a central plan, covered by a dome about 20 meters in diameter in Guasila (in the province of Cagliari, Italy). Already during the construction, Cima highlighted a series of problems related to the quality of the materials used, the technical skills of the builders, and the cost-cutting measures taken during construction, which proved to be the cause of the deterioration that characterised the life of the building and the numerous restorations works that have occurred over time. Faced with this situation, the Municipality of Guasila has commissioned a group of researchers from the DICAAR (Department of Civil, Environmental and Architectural Engineering) of the University of Cagliari to carry out a multidisciplinary study aimed at defining in a complete and exhaustive way the state of conservation of the church. Overall, this study concerned historical-critical analysis, geometric-architectural survey, structural survey and analysis, analysis of materials and the study of foundations involving architectural historians, geomatics, structuralists, petrographers and geophysicists.In detail, this paper presents the integrated results obtained from archival research on the restoration works, the close range photogrammetric (CRP) and minero-petrographic surveys performed for implementing the knowledge of the painted dome of this basilic, characterised by several static problems since its construction. The support of the three fields of research has allowed not only to define an in-depth level of information concerning the origins of the issues in terms of geometries, materials and building techniques for the design of future interventions of conservation of the structures, but also to define potentialities and accuracy of this interoperable approach in the study of other similar case studies.
3D HIGH-QUALITY MODELING OF SMALL AND COMPLEX ARCHAEOLOGICAL INSCRIBED OBJECTS: RELEVANT ISSUES AND PROPOSED METHODOLOGY
Authors: Lastilla L. , Ravanelli R. , Ferrara S.
Published: May 2019

Abstract. 3D modelling of inscribed archaeological finds (such as tablets or small objects) has to consider issues related to the correct acquisition and reading of ancient inscriptions, whose size and degree of conservation may vary greatly, in order to guarantee the needed requirements for visual inspection and analysis of the signs. In this work, photogrammetry and laser scanning were tested in order to find the optimal sensors and settings, useful to the complete 3D reconstruction of such inscribed archaeological finds, paying specific attention to the final geometric accuracy and operative feasibility in terms of required sensors and necessary time. Several 3D modelling tests were thus carried out on four replicas of inscribed objects, which are characterized by different size, material and epigraphic peculiarities. Specifically, in relation to photogrammetry, different cameras and lenses were used and a robust acquisition setup, able to guarantee a correct and automatic alignment of images during the photogrammetric process, was identified. The focus stacking technique was also investigated. The Canon EOS 1200D camera equipped with prime lenses and iPad camera showed respectively the best and the worst accuracy. From an overall geometric point of view, 50 mm and 100 mm lenses achieved very similar results, but the reconstruction of the smallest details with the 50 mm lens was not appropriate. On the other hand, the acquisition time for the 50 mm lens was considerably lower than the 100 mm one. In relation to laser scanning, the ScanRider 1.2 model was used. The 3D models produced (in less time than using photogrammetry) clearly highlight how this scanner is able to reconstruct even the high frequencies with high resolution. However, the models in this case are not provided with texture. For these reasons, a robust procedure for integrating the texture of photogrammetry models with the mesh of laser scanning models was also carried out.
TECHNOLOGY 4.0 FOR BUILDINGS MANAGEMENT: FROM BUILDING SITE TO THE INTERACTIVE BUILDING BOOK
Authors: Laurini E. , Rotilio M. , Lucarelli M. , De Berardinis P.
Published: May 2019

Abstract. The main result of the research that we intend to illustrate is the connection between the contents of 4.0 Industry (Ciribini 2018), and the information sharing with BIM design (Lucarelli 2018), through the insertion into a single data container (black storage box), of all the sensors inherent to the entire building process, to monitor the building from the early construction phases and obtain a precise history about it. The goal is to create an "As Built" model flanked by the interactive digital building book, capable of an automatic upgrade depending on the variation of the monitored data during the useful life of the building.The aim of this project is to exploit the use of IoT (Gabriele 2015), for the data communication to the black box (Smart Monitoring Building Box – SMBBox) installed in the building from the beginning of the construction site, in order to initially monitor the status work progress and safety management on site, and subsequently, thanks to the combination with the BIM model for data management, it will be possible to digitize the physical and functional characteristics of the case study object.The methodological approach is based on the following steps: BIM modeling; sensor design and installation and data container; data collected updating; "As Built" model creation; Interactive building Drafting. This method is being carried out on a restricted building located in the historic center of L'Aquila, subject to seismic improvement as a result of the damage caused by the 2009 earthquake.

Abstract. The present article aims to consider the added value attached to the usage of new technologies in a project aimed to study heritage. Indeed, multimedia devices could be used to create representations useful to develop and disseminate information integrating the architectural and territorial framework and to reach a general understanding.The processed data come from a research project, based on an interdisciplinary approach, address to the study of medieval buildings in Armenia, Vayots Dzor region, with the aim of studying and understanding the cultural heritage.Three different technologies are used to visualize and disseminate the results of the analyses carried out: the video, the hologram, and the virtual reality. These digital visualization methods enable experts to make the topics investigated accessible and comprehensible to a wider general public with a didactic and informative aim.The solid 3D-model of the site allows to virtually reproduce the reality and to provide a spatial perception of the site. Indeed, it is a neutral base, represents the morphological conformation and settlements, a landscape whose reference points are easily identified with the historical architectures, helping the public and spectators to get oriented inside the territory. These methods of representation allow to move from general view to particular, or to a different frame appropriate to the addressed topic. Thus, it binds the scientific research with the visual part, and enable communication, even in a context where it is difficult to use a common spoken or written language.

Abstract. Many European infrastructures dating back to ’50 and ’60 of the last century like bridges and viaducts are approaching the end of their design lifetime. In most European countries costs related to maintenance of infrastructures reach a quite high percentage of the construction budget and additional costs in terms of traffic delay are due to downtime related to the inspection and maintenance interventions. In the last 30 years, the rate of deterioration of these infrastructures has increased due to increased traffic loads, climate change related events and man-made hazards. A sustainable approach to infrastructures management over their lifecycle plays a key role in reducing the impact of mobility on safety (over 50 000 fatalities in EU per year) and the impact of greenhouse gases emission related to fossil fuels. The events related to the recent collapse of the Morandi bridge in Italy tragically highlighted the sheer need to improve resilience of aging transport infrastructures, in order to increase the safety for people and goods and to reduce losses of functionality and the related consequences. In this focus Structural Health Monitoring (SHM) is one of the key strategies with a great potential to provide a new approach to performance assessment and maintenance over the life cycle for an efficient, safe, resilient and sustainable management of the infrastructures. In this paper research efforts, needs and challenges in terms of performance monitoring, assessment and standardization are described and discussed.

Abstract. Thanks to the recent worldwide spread of drones and to the development of structure from motion photogrammetric software, UAV photogrammetry is becoming a convenient and reliable way for the 3D documentation of built heritage. Hence, nowadays, UAV photogrammetric surveying is a common and quite standard tool for producing 3D models of relatively large areas. However, when such areas are large, then a significant part of the generated point cloud is often of minor interest. Given the necessity of efficiently dealing with storing, processing and analyzing the produced point cloud, some optimization step should be considered in order to reduce the amount of redundancy, in particular in the parts of the model that are of minor interest. Despite this can be done by means of a manual selection of such parts, an automatic selection is clearly much more viable way to speed up the final model generation. Motivated by the recent development of many semantic classification techniques, the aim of this work is investigating the use of point cloud optimization based on semantic recognition of different components in the photogrammetric 3D model. The Girifalco Fortress (Cortona, Italy) is used as case study for such investigation. The rationale of the proposed methodology is clearly that of preserving high point density in the model in the areas that describe the fortress, whereas point cloud density is dramatically reduced in vegetated and soil areas. Thanks to the implemented automatic procedure, in the considered case study, the size of the point cloud has been reduced by a factor five, approximately. It is worth to notice that such result has been obtained preserving the original point density on the fortress surfaces, hence ensuring the same capabilities of geometric analysis of the original photogrammetric model.
LIDAR DATA ANALYSES FOR ASSESSING THE CONSERVATION STATUS OF THE SO-CALLED BATHS-CHURCH IN HIERAPOLIS OF PHRYGIA (TR)

Published: May 2019

Abstract. The LiDAR technology has aroused considerable interest in the field of structural study of historical buildings, aimed at the structural assessment in the presence of different states of stresses and at the evaluation of the health status.The interest is due mostly by the ability of generating models of the built structures being able to predetermine different levels of schematization, two-dimensional and three-dimensional, in order to be able to perform evaluation processes assigning simplified geometric contents that correspond to the physical reality of the artefacts.This paper intends to report some results of these experiences applied in archaeological domain, to the so-called Baths-Church at Hierapolis in Phrygia (Pamukkale, TR). In particular, the generation of accurate models from dense clouds and their reduction to models with simplified geometries too, is explored, with the further aim of testing automated strategies for features detection and editing process that leads to appropriate models for visual and analytical structural assessment. The accuracy and density parameters of the LiDAR clouds will be analysed to derive orthophotos and continuous mesh models, both to obtain the best results from the application of research algorithms such as region growing to detect blocks, and to allow visual analysis on digital models and not on site.The ability to determine with high accuracy both the size and the anomalies of the wall systems (out of plumb and other rotation or local mechanisms of collapse), together with the possibility of identifying the lay of the individual drywall blocks and also the signs of cracks and collapses, allow deriving suitable models both for FE (Finite Elements) analysis and DE (Discrete Elements) analysis, as well as analytical ones.

Published: May 2019

Abstract. Conservation planning is a complex process involving a wide range of agents such as architects, engineers, conservators and archaeologists. Their integrated inputs contribute to the definition of criteria for the conservation project and the conservation strategy. In this process, graphical documentation is a common denominator to all involved areas-of-expertise. It provides the basis for the dialog between agents coming from different fields of knowledge that often don’t speak the same technical language nor share the same codes. The way this dialog can be improved through documentation is the main motivation of our study.In this paper we analyze the requirements of digital documentation in Cultural Heritage (CH) conservation strategies, and we tackle the fundamental role of photogrammetry and terrestrial laser scanning (TLS), and integrated implementation throughout the several steps, from the fieldwork to the conservation planning for CH sites. The described process is demonstrated through the case study of ‘the conservation project of the historic walls of Lagos’, in south Portugal.After introduction and related work, the study is structured in four main sections. In the second section, we present the case study and conduct an analysis of existing data and preliminary synthesis of heritage values related to the historic walls of Lagos. Second section corresponds to an overview of the project workflow. This spans from recording and documentation, considering geometry, colour, light, materials and degradation forms; to their analysis and diagnosis, resulting in criteria and guidelines for the intervention actions. Third section emphasises on how the simultaneous use of photogrammetry and TLS in the documentation process, and its relationship with other methods and techniques, introduces a distinctive character in the conservation project. Fourth section is about the documentation process with photogrammetry and TLS. Finally, fifth section focus in the analysis and architectural project.

Published: May 2019

Abstract. The historical and cultural relevance of the City Walls built by the ‘Serenissima’ Republic of Venice in the second half of 16th century was recognized in 2017 by the insertion of Bergamo, together with other Venetian Fortresses in Italy, Croatia and Montenegro, in the World Heritage List of UNESCO as transnational site. In the framework of the nomination to the WHL, the City Council together with the University of Bergamo started a campaign of studies and surveys aimed to prepare a conservation planning. The goal of this plan is to assure a constant monitoring of this artwork, so that a strict routine of controls, cleaning and small strengthening works would prevent more relevant interventions, which could corrupt the material integrity of the building.This paper delineates the methodological and operational workflow applied to the preparation of the maintenance plan, now in progress, for the Venetian City Walls of Bergamo, where the photogrammetric survey by means of UAV plays an important role. The different working phases, the adopted instrumentation, the difficulties encountered and the choices made are described, and some case studies are also illustrated that represent well the typical problems encountered for the conservation of the Walls.
GEOMATICS IN BRIDGE STRUCTURAL HEALTH MONITORING, INTEGRATING TERRESTRIAL LASER SCANNING TECHNIQUES AND GEOTECHNICAL INSPECTIONS ON A HIGH VALUE CULTURAL HERITAGE

Published: May 2019

Abstract. The paper presents preliminary findings from a research study designed to assess the health status of a medieval bridge built on 1500 under the Medici dynasty over the river Sieve, close to Florence. The structure, a two span stone bridge with a main central pillar, experienced some restructuring interventions from 1555 to the present. The left span has been closed for some decades, and for many years the water has been allowed to float under it in case of severe flood only. At the beginning of year 2000 the left span has been opened to the regular flux of water. After opening, a maelstrom has been noticed as permanently present at the main pier’s basis highlighting the presence of a fracture in the concrete base around the central pile of the bridge. In order to investigate structural health and to assess bridge’s stability structural inspections and hydraulic surveys have been carried out. This manuscript reports Terrestrial Laser Scanning (TLS) survey results. Surface comparisons to identify anomalies and defromations have been carried out by exploiting Two TLS campaigns that were performed within a 6 years time span.

GEOMATIC TECHNIQUES FOR THE COLONNADE STRUCTURAL ANALYSIS OF THE HISTORICAL “CHIARAMONTE STERI” BUILDING
Authors: Orlano P.
Published: May 2019

Abstract. The monitoring of building structures has an increasingly important role in the engineering field, above all because they are concerned with the impact that such structures have in the area where they were built. Often, when walking through the old town centres, we realize just how obsolete and dangerous some buildings (even historic-cultural ones) are. The interest of some local governments in this problem has led, in the last few years, to the study and the trying out of measuring and monitoring methods which, quickly and at low cost, allow to define the extent of the deformation and the degrade in an accurate and reliable way.The Courtyard of “Palazzo Steri - Chiaramonte” is composed of a colonnade on two orders. On the ground floor there are eight columns made up of cylindrical overlapped tuff bricks, with the same radius, while at the first floor there are 12 marble columns with a reduced section compared to those on the ground floor. All the columns have been characterized by a displacement compared by the vertical direction. This paper aim is describing the used methodology in order to evaluate the structural displacements of the colonnade and to monitor them in the future.
ON THE RELATIONSHIP BETWEEN GEOMATICS AND CONSERVATION: LESSONS LEARNED FROM INTEGRATED RESTORATION LABORATORIES
Authors: Pracchi V. , Barazzetti L.
Published: May 2019

Abstract. The paper aims at investigating results, research perspectives, and limitations emerging from the synergy between geomatics and conservation. Recent didactic experiences carried out in restoration laboratories at Politecnico di Milano are illustrated and discussed. The authors tested innovative techniques for surveying with particular attention to the conservation problem. The aim was to exploit novel 360° virtual/immersive environments able to collect and manage data traditionally useful for conservation projects such as thematic maps of historical building techniques, construction technologies, deterioration pathologies, and data from diagnostics. Results are presented for two case studies completely different in terms of shape, pathologies, and reuse: the Albergo Diurno di Porta Venezia in Piazza Oberdan, and the Church of San Vittore and the Forty Martyrs (both in Milan). The work carried out with students allowed one to evaluate the pros and cons of a novel 360° immersive solution. The outcomes suggest other possible uses in related activities. The last part of the paper reconsiders the proposed “renewed” relationship between geomatics and restoration. Starting from the basic requirements of existing regulations, the paper explores the research fields and practical applications that could benefit from an intersection of geomatics and restoration.
A GIS TOOL FOR THE MANAGEMENT OF SEISMIC EMERGENCIES IN HISTORICAL CENTERS: HOW TO CHOOSE THE OPTIMAL ROUTES FOR CIVIL PROTECTION INTERVENTIONS
Authors: Artese S. , Achilli V.
Published: May 2019

Abstract. Italy hosts a considerable part of the world's great art treasures. This great heritage must be protected from risks deriving from a territory characterized by hydrogeological problems and high seismicity. For these reasons, despite the preventive measures that can be foreseen, the need to face emergencies is recurrent. The main instrument to address the hydrogeological and seismic emergencies is the Municipal Civil Protection Emergency Plan. In this plan, both strategic viability and strategic buildings (whose collapse could cause significant damage to the historical, artistic and cultural heritage) must be identified.The paper proposes a methodology, using a GIS platform, useful for achieving two objectives: (1) planning of safe routes in case of critical conditions and (2) identification and planning of safety interventions, thus assigning appropriate priorities to the buildings to be restored, based not only on their relevance to road use, but also on cost considerations.

This study was conducted to evaluate the effect of Origanum vulgare L. Hirtum essential oil on the oxidation stability of raw chicken meat. Oregano essential oil was applied in a different way, on the one hand in a feed for broiler chickens (E1) and on the other hand on a surface of chicken thighs (E2). Broiler chickens were fed during the experimental period in the all groups with commercial feed mixtures except the experimental group of E1 (with the addition of 0.05% oregano essential oil, 50 g EO per 100 g of the feed mixture). In E2 was application of oregano essential oil (0.5%) on surface of thighs 1 mL per 60 g of meat realized. The oxidative stability of the chicken meat was investigated in the same way, 8th days after vacuum-packed and stored at temperature 4 °C and 6, 9 and 12 months after vacuum-packed and storage at -18 °C. The samples of the E1 consisted of breast and thigh muscles with skin (150 g) and of the E2 thigh muscle with skin (60 g). The impact of oregano essential oil was measured by content of fat and peroxide value (PV). Fat content in both experiments was not affected by storage time and EO addition. Content of chicken meat fat in E1 in control group ranged between M = 9.64 – 12.95 g.100 g-1 and in experimental group contained similar amount of fat mean from M = 9.94 – 12.24 g.100 g-1; E2: in control group M = 7.01 – 7.73 g.100 g-1 and in experimental group M = 6.15 – 8.03 g.100 g-1. Measured peroxide values confirm that oregano essential oil has effect on broiler chicken meat oxidative stability, if applied to feed, manifested statistically significant differences between control and experimental group. The mean of peroxide value in control group of E1 was M = 0.58 –3.60 µmol O2.kg-1 and in experimental group was M = 1.06 – 2.11 µmol O2.kg-1. We found not statistically significant difference in peroxide values, if applied oregano essential oil to raw chicken meat. The results impact of oregano essential oil on chicken meat comparable to control group, but a tendency to improve oxidative stability was indicated.

To provide food for children with food allergy or food intolerances represents an increasingly important role in school catering services. The number of children with food intolerances is growing continuously; therefore, it is necessary to improve the knowledge of foodservice workers, who are responsible for food provision in school catering units in relation with food intolerances, food allergies. The main goal of our research is to assess and analyze the knowledge of food service workers and food handlers on food intolerances and to determine those factors, which may influence their knowledge. Our research was conducted by using paper and pencil questionnaires. The mean of test results was 89,16% while deviation was 12,26%. There were no correlations between the test results and respondents”™ education level, age group and the number of years working in food catering sector, and only partial correlation was detected with the job of the respondents. Based on the answers the food handling techniques of diet foods represented the poorest results. Our findings proved that the knowledge and food handling practice of food handlers regarding food intolerances and the preparation of diet meals should be improved.

Objective: To identify factors contributing to changes on quality, productivity,
and safety outcomes during a large commercial electronic health record (EHR)
implementation and to guide future research.Methods: We conducted a mixed-methods study
assessing the impact of a commercial EHR implementation. The method consisted of a
quantitative longitudinal evaluation followed by qualitative semi-structured, in-depth
interviews with clinical employees from the same implementation. Fourteen interviews
were recorded and transcribed. Three authors independently coded interview narratives
and via consensus identified factors contributing to changes on 15 outcomes of quality,
productivity, and safety.Results: We identified 14 factors that potentially affected the
outcomes previously monitored. Our findings demonstrate that several factors related to
the implementation (e.g., incomplete data migration), partially related (e.g.,
intentional decrease in volume of work), and not related (e.g., health insurance
changes) may affect outcomes in different ways.Discussion: This is the first study to
investigate factors contributing to changes on a broad set of quality, productivity, and
safety outcomes during an EHR implementation guided by the results of a large
longitudinal evaluation. The diversity of factors identified indicates that the need for
organizational adaptation to take full advantage of new technologies is as important for
health care as it is for other services sectors.Conclusion: We recommend continuous
identification and monitoring of these factors in future evaluations to hopefully
increase our understanding of the full impact of health information technology
interventions.

É de tamanha relevância pesquisar acerca do pensamento computacional e suas possíveis alterações fisiológicas no cérebro de estudantes do ensino fundamental. Este artigo apresenta um recorte dos dados coletados de uma pesquisa que pretende identificar as áreas do cérebro que são ativadas antes e depois de um curso de aprendizado de lógica computacional, através de uma ferramenta com fundo educacional com estrutura interativa, Scratch, com público alvo em crianças do ensino fundamental. Para isto, é utilizado o sistema BCI (Brain Computer Interface), uma interface entre o cérebro e o computador, através da qual são mapeados processos e estados mentais. Além disso, utilizar-se-á a ferramenta ActiCHamp, um amplificador de canal ativo com canais auxiliares usados para uma gama completa sensores de Biosinais. Também será utilizado o OpenVibe, que permite projetar, testar e utilizar sistemas BCI, para fazer a coleta de dados pré e pós aprendizado. A base teórica se embasa em pesquisas das: neurociências, educação, aprendizado e tecnologia. O estudo foi realizada em um grupo de alunos do ensino fundamental em que foi possível concluir que o pensamento computacional ocasiona alterações fisiológicas no cérebro de estudantes das séries finais do ensino fundamental de uma escola pública, com intuito de melhora na resolução de problemas.

Aim: The study aimed to clarify students’ learning about medical care teams through clinical practicum based on the World Café method, to find suggestions useful for developing new methods of education.Methods: The “roles of nursing in improving medical care teams” reported by students were qualitatively and descriptively analyzed.Results: Six core categories were identified concerning the roles of nursing in medical care teams, including [Staying close to patients to support them], [Providing information and using obtained information for care as much as possible], [Hub station for interpersonal relationships], [Realizing patient-centered medicine], [Key approaches to promote medical care teams ] and [Lubricant for medical care teams].Conclusions: Education using the World Café method helps students integrate their practice effectively based on theories and experiences, remember during training what has been already learned and pay attention to medical care teams. Furthermore, supportive guidance, such as providing feedback, was useful for them to develop more flexible and deeper thoughts.
