Objective: to detect asthenia, weariness and sleep disorders in pediatricians. Material and methods. Cross-sectional study of 44 pediatricians with the use of a package of psychometric tools (scale for assessing weariness SB-2003, Pittsburgh Insomnia Rating Scale (PIRS), subjective rating scale of asthenia MFI-20). Results. 42 (95 %) of the respondents from the study group revealed moderate or severe emotional weariness. Only 5 (11 %) of the respondents did not reveal any signs of asthenic symptomatic complex. All the respondents in the survey had this or that form of a sleep disorder. Conclusion. The job of a pediatrician involves high-level professional emotional stress, which affects the quality of life, determines the psychological status and, later, somatic well-being, indirectly influencing the satisfaction of consumers of medical services. Asthenic symptoms, sleep disorders and emotional weariness, which are common among doctors of this specialty, may be indicative of circadian rhythm disorders associated with professional desynchronosis. The use of tranquillizers and sleeping pills, consumption of alcohol or other psychoactive substances in order to correct sleep disorders show a decrease or a failure in the adaptation potential of pediatricians under the impact of extreme loads and professionally deterministic disturbances of biological rhythms, inefficient psychological protection.

Objective: to determine correlative relations between the indoor volume activity of radon and the parameter defining the content and nature of radon in rocks. Material and methods. The results of indoor volume activity in rural settlements of Gomel and Mogilev regions measured by specialists of Scientific and Research Institute of Industrial and Marine Medicine (Saint Petersburg) in 1992, the exposure doze power maps before the Chernobyl Disaster made by specialists of the Republican Unitary Enterprise «Belgeology» over 1969-1985, and the geologist rocks maps with various uranium content were used as the basis for radon risk mapping. Results and conclusion. We have proposed the complex radon factor that may be calculated as the relative content of uranium in rocks multiplied by the relative value of rock penetration. The regression dependence of volume activity on the complex radon value taken on average in Gomel and Mogilev regions has essentially high correlative coefficient - 0.76. Such correlation is enough to use this parameter based on the measurements of rock radon characteristics in Gomel and Mogilev regions for radon risk mapping.

Emerging Drugs for Generalized Myasthenia Gravis
Authors: Ndegwa Sarah , Mierzwinski-Urban Monika
Published: February 2022

Horizon Scan reports provide brief summaries of information regarding new and emerging health technologies. These technologies are identified through the CADTH Horizon Scanning Service as topics of potential interest to health care decision-makers in Canada. This Horizon Scan summarizes the available information regarding emerging targeted therapies for the treatment of generalized myasthenia gravis (MG).

MG is a rare and chronic autoimmune disease in which autoantibodies attack specific proteins in the neuromuscular junction, resulting in muscle weakness. Many patients develop generalized MG resulting in severe fatigable muscle weakness with difficulties in facial expression, speech, swallowing, and mobility.

Current treatments for MG include anticholinesterase inhibitors, systemic corticosteroids, and nonsteroidal immunosuppressive drugs. IV immunoglobulins or therapeutic plasma exchange are the current treatment options for patients with severe or acutely worsening generalized MG. Thymectomy is also considered a treatment option for patients with generalized MG who fail to respond to immunotherapy or have intolerable side effects.

In this scan, we have reviewed 6 new treatment strategies that target specific areas of the immune system involved in the pathogenesis of MG: efgartigimod, rozanolixizumab, zilucoplan, ravulizumab, batoclimab, and nipocalimab. Phase II and III clinical trials have shown that these drugs may potentially benefit patients with generalized MG based on improvements in measures of disease severity and functional disability.

The information presented is limited in that most of the available evidence comes from phase II trials that were designed to primarily investigate safety and tolerability based on small sample sizes, short trial duration, and narrow inclusion criteria. Therefore, findings do not reflect current standard of practice for maintenance therapy for generalized MG in the real-world setting.

Considerations for future use include identifying the population that will most likely benefit from therapy and evaluating these drugs for rare and serious adverse events. Factors such as ease of administration, dosing schedule, and cost are all important factors that will help determine uptake and place in therapy for these emerging targeted therapies.

Published: February 2022

Abstract. In 1985, the World Heritage Committee inscribed the site “Painted Churches in the Troodos Region” of the Republic of Cyprus on the UNESCO World Heritage List. The latter included nine Byzantine and Post Byzantine Churches to which a tenth church was added in 2001. In the framework of the IH-AT project, all the churches and the premises in their proximities were analysed using a wide array of non-destructive digital methodologies coupled with more traditional art-historical studies. Image- and Range-based techniques were used to document all the morphological features of the buildings with the final goal of understanding their humble architecture. Additionally, a Ground Penetrating Radar (GPR) was performed to investigate the presence of buried structures that, according to historical sources, were once surrounding the religious sites.For the exploitation and visualization of the extensive database by the scientific community and the public at large, a web portal comprised of reliable and efficient technology-ready tools have been developed.The proposed methodology was implemented to provide new insights on the churches’ architectural features; confirm the presence or absence of buried remains of archaeological interest; and help heritage professionals, with lack or minimal programming skills, to customize online visualizations of 3D interactive models.
PERSPECTIVE RESTITUTION FROM VIEW CAMERAS PHOTOS
Authors: Agnello F.
Published: February 2022

Abstract. The paper aims at discussing the accuracy of perspective restitution from view camera photos; view cameras are non-standard cameras frequently used in the past century for on field shooting of buildings and urban sites; this is why the reconstruction of lost buildings often deals with photos taken with a view camera. The case study chosen for the proposed experiment is an urban complex built in Palermo in the ‘50s. The site features a very regular layout with surfaces at right angle, that supports the graphic reconstruction of photos’ inner and outer orientation. The site has been surveyed with a laser scanner; the point cloud provided the metric information needed for the evaluation of the accuracy of perspective restitution. The experiment used three sets of photos: a photo taken by Studio Alinari in the ‘60s; a couple of photos taken during the research work with a view camera; a photo taken with a standard mirrorless camera.The results of the experiment prove that view cameras do not modify the projective layout of perspective and that the accuracy of restitution from view camera photos is comparable to the accuracy of restitution from images taken with a standard camera.
THE RECOGNITION OF HERITAGE QUALITIES FROM FEATURE-BASED DIGITAL PROCEDURES IN THE ANALYSIS OF HISTORICAL URBAN CONTEXTS
Authors: De Marco R. , Pettineo A.
Published: February 2022

Abstract. The documentation of historical architectural heritage in urban contexts involves the consideration of planning adaptations of settlements and landscape, related to the identification of formal and semantic qualities. In particular, the identification of cultural significance of Heritage building units can find correspondence in geometrical features that are documented within the urban asset. In this way, urban monitoring, in an increasingly automated way, can support the identification and characterization of semantic elements also regarding Heritage objects, observing the invariance and conservation of formal constants in urban dynamic assets.Considering the experimental case study of Solikamsk historical center, belonging to Upper Kama route (Russia), a multi-instrumental strategy of spatial survey is applied, evaluating data coverages and resolutions. This analysis defines a preliminary framework to develop further processes of 3D triangulation and reality-based meshing. The morpho-metric detail of final models constitutes the basis for the computing test of feature-based procedures, including regions recognition and mesh segmentation, which can be calibrated for shape qualities and scales, reaching a preliminary modeling classification of Heritage and urban building units.
FIND OUT THE PRINTING MATRIX OF THE NEAPOLITAN MARKS WITH INVERSE READINGS OF THE SURVEY DATA
Authors: Fregonese L. , Gallo M. , Pulcrano M. , Scandurra S. , Del Vecchio F.
Published: February 2022

Abstract. The paper presents the first results of the metric and geometric investigations carried out in the analysis of the stamps on Greek-Italic amphorae of Neapolitan production, found during the archaeological excavation of Piazza Nicola Amore, in Naples, Italy.The experiments were carried out with a view to defining a methodological process useful on the one hand to document in a digital archive the three-dimensional morphology of the artefact under investigation, and on the other to allow new readings, through a manipulation of the data that goes beyond the physical limits of the artefact itself. In particular, the research presented here proposes the topological investigation for the identification of stamps obtained from the same punch and therefore the possibility of ideally reconstructing the printing matrix.Since the stamps left by the punches on the amphorae are impressed at millimetric depths, the stamps are not always easy to read using traditional archaeological documentation methods. The research operations therefore began with the digitisation of a substantial number of finds by means of three-dimensional, reality-based surveys of sub-millimetre detail. Before proceeding with specific correspondence analyses, the archaeological classification based on the typological similarities of the marks was of great support.

ACCURACY IMPROVEMENT OF A IMMS IN AN URBAN SCENARIO
Authors: Marotta F. , Achille C. , Vassena G. , Fassi F.
Published: February 2022

Abstract. Indoor Mobile Mapping Systems (IMMSs) technologies are becoming increasingly popular thanks to the possibility of acquiring a massive amount of 3D data in a fast and effective way in those areas where GNSS signal is unavailable, like urban canyons, densely vegetated areas, underground sites and buildings. They offer an efficient way to produce point clouds but with noticeably lower accuracy than the traditional Terrestrial Laser Scanning (TLS). The present paper wants to analyse two different methods to improve the accuracy of the point cloud coming from an IMMS survey in a vast urban scenario. The first approach uses points collected during an RTK GNSS survey as Ground Control Points (GCPs). The second one involves TLS static scans as Ground Control Scans (GCSs). Both these procedures allow us to introduce constraints before generating the rigid final point cloud. The tested IMMS is the Backpack Heron MS Twin Color, produced by Gexcel S.r.l. The instrument was tested during the acquisition of the historical centre of Meda (MB) in the northern part of Italy. Results show that in those areas between the constraints, the maximum error of residuals on checkpoints is some decimetres. The IMMS has allowed us to quickly survey a vast area not otherwise obtainable with traditional survey techniques. The developed procedures proved to be essential for proper reconstruction of the environment.
THE LOST MEMORY OF INDUSTRIAL PLACES: THE IPANEMA BLAST FURNACE
Authors: Balzani M. , Rossato L.
Published: February 2022

Abstract. This contribution is based on a joint research project developed by the University of Ferrara, Department of Architecture (Italy) and the Escola Politecnica USP of São Paulo (Brazil) by the which it was possible to scan the interior and exterior surfaces of the ancient blast furnaces of São João do Ipanema, an extraordinary example of industry of cast iron production of the XIX century.The research was aimed at investigating the evolution of the blast furnace technique exploring a surprisingly rich Brazilian technical literature, with description records and drawings dated between the late 19th and early 20th centuries. Beside historical documentation it was also implemented on site a 3D survey campaign of the furnaces to understand how the profiles were modified along the time.The first outputs of the project were thus focused on the evaluation of the transformation of the equipment in terms of more efficient shapes able to enhance the relationship between blast furnace profile fuel consumption and productivity.The use of accurate digital technology, the following CAD elaboration of the chimney, the 3d model and the comparison with XIX century technical drawings confirmed that European directors of the plant were familiar with the most advance technical and scientific procedures and brought to the site a great technological improvement by an innovative know-how.
A HYBRID POINT CLOUD REALITY CAPTURE FROM TERRESTRIAL LASER SCANNING AND UAV-PHOTOGRAMMETRY
Authors: Razali A. F. , Ariff M. F. M. , Majid Z.
Published: February 2022

Abstract. Point clouds are a digital representation of physical objects or buildings that exist in real world. There are many sources that a point cloud can come from such as a terrestrial laser scanner (TLS) or an unmanned aerial vehicle (UAV). This paper presents a simple method of integrating point clouds from two (2) data sources; TLS and UAV using simple alignment of rigid body transformation method known as Point Pair Picking (PPP). The point cloud data are the representation of details of a one-story building located in Johor Bahru, Malaysia. The process of aligning two (2) separate clouds into one (1) dataset requires initial processing such as noise removal before the alignment process was started. A laser (LAS) formatted data were formed so that it compatible with the PPP process. As the result, a high dense hybrid cloud-model was produced covering complete details of the building. This shows that integration of point clouds could improve 3D documentation assessment such as Building Information Modelling (BIM) by contributing richer semantic information.
CROSSED EXPERIMENTATIONS OF LOW-ALTITUDE SURVEYS FOR THE DETECTION OF BURIED STRUCTURES
Authors: Van Dongen A. , Eeckhout P. , Lo Buglio D.
Published: February 2022

Abstract. Drones are becoming essential in the field of heritage surveying, especially for large-scale archaeological site. The precision offered by the new survey tools (UAVs, sensors, processing software, etc.) should make it possible to obtain enough information to complete the plan of a site on an urban scale.This paper shows the use of two types of sensors embedded simultaneously on a UAV with the aim of highlighting information that is often difficult to detect on the ground. By crossing RGB and thermal data, certain built-up limits seem to appear. Thanks to this new information, hypotheses of the urban structure are proposed. In other words, the aim is to bring out circulation hypotheses within a large complex archaeological site. Unlike the field of architectural survey where thermography is widely used, for example, to identify certain building pathologies, in archeology this technique does not seem to be part of the traditional survey pipeline and even less on large-scale sites. The possibility of using a third type of sensor is also sketched. The aerial-GPR would in fact make it possible to confirm the presence of a buried structure without having to go through systematic excavation and could provide a three-dimensional image of the ruins.
3D MODELLING METHOD OF HIGH ABOVE GROUND ROCK ART PAINTING USING MULTISPECTRAL CAMERA

Published: February 2022

Abstract. This paper presents a developed methodology of 3D modelling of rock art painting located at high above shelter floor based on close-range photogrammetric technique. Instead of using elevated devices to reach inaccessible paintings due to high elevation, the developed method proposed a simple technique. The camera was mounted on an expandable pole to acquire the panel with normal and tilted camera settings. Due to inaccessibility to place the control point marker on the panel surface, the distribution of photo control was positioned below the panel. Based on the configuration, the image of the panel was acquired using the low-spatial resolution multispectral camera in a two elevated strips position that imitates the aerial photogrammetry flight line. The camera was set parallely to the painting panel on both strips, with additional tilted geometry included at the upper strip of the camera block. The acquired multispectral images were then processed using commercial SfM photogrammetry software to generate a 3D point cloud. The accuracy of constructed point cloud was then analysed by comparing it with the point cloud generated using a terrestrial laser scanner (TLS). The result has shown that the multispectral 3D point cloud has a small deviation against the TLS point cloud. The mean deviation was -0.43mm, indicating a slight downscaled on the multispectral point cloud.

Published: February 2022

Abstract. A workflow for editing and rendering 360° images (also called spherical or equirectangular images) is illustrated and discussed. The aim was to develop a novel procedure able to overcome limitations induced by deformations in images acquired with low-cost 360° cameras. Editing and rendering are carried on equirectangular projections using a dynamic procedure that turns images into traditional central perspectives, enabling the user to change viewing directions, modify digital content, and store the changes in the original files. Integration of the rendered projections with traditional outputs of digital recording operations as well as other deliverables of the architectural restoration project is also discussed. Finally, the development of a web-GIS application that stores and shares multiple deliverables (including the newly proposed renders) is presented.

The aim of this communication is to present the advantages and disadvantages of a Scan-to-BIM process applied to a heritage building in order to obtain advanced technical drawings to be used in the analysis and illustration of the project. The whole process described includes: the survey planification and data acquisition with a Terrestrial Laser Scanner; the processing and cleaning of the point cloud; the 3D mathematical modelling; a proposal for semi-automatic modelling of organic elements; and the import of the final model into a BIM environment. Rhinoceros (McNeel) and Revit (Autodesk) are the main programs used. The crucial aspect of this workflow is found at the moment of importing the geometrical model into Revit, having to accommodate the criteria of this program in terms of tolerances, geometric structure of the solids, incompatibilities with NURBS libraries, etc. The result is a BIM model divided into families and subcategories where visual attributes can be assigned per element, parameterized and other visual information can be added (orthophotographs, wireframe analysis drawings, etc.). In other words, a 3D model from which highly configurable advanced representations (plans, vertical sections, perspectives, isometric exploded view, etc.) can be obtained and with which to generate analyses from the field of Architectural Graphic Expression.

Abstract. Introduction: Septic arthritis and osteomyelitis of the pubic symphysis
(SAS) are rare conditions with nonspecific symptoms leading to diagnostic
delay and treatment.
Aim: We draw awareness to this condition elucidating the diagnostic
procedures, surgical intervention and antibiotic management.
Methods: This entail a retrospective follow-up study of 26 consecutive patients, median
age of 71 years (range: 48–89) surgically treated for septic arthritis of
the pubic symphysis between 2009 and 2020. Patient files, diagnostic
imaging and bacterial cultures were evaluated.
Results: Before diagnosed with SAS, 21 of the patients had previous pelvic
surgery (16 due to malign conditions, 5 due to benign conditions), while 5 of
the patients were not previously operated. Median follow-up period after SAS
surgery was 18.5 months (range: 8 to 144.5 months). Dominating symptoms were
severe suprapubic/pubic pain (n = 26), gait difficulties (n = 10) and
intermittent fever (n = 9). Diagnostic delay was between 1 and 12 months.
The diagnostic imaging included magnetic resonance imaging (MRI) (n = 24),
computer tomography (CT) (n = 17) and/or PET-CT (n = 10), predominantly
displaying bone destruction/erosion of the symphysis (n = 13), abscess
(n = 12) and/or fistula (n = 5) in the adjacent muscles. All patients
underwent surgical debridement with resection of the symphysis and received
a minimum of 6 weeks antibiotic treatment. Fourteen patients presented with
monocultures and 4 patients with polycultures. Five patients underwent at
least one revision surgery. Twenty-three patients experienced postoperative
pain relief at 6 weeks follow-up, and 19 patients were ambulant without
walking aids.
Conclusion: SAS are rare conditions and should be suspected in patients
with infection, pubic pain and impaired gait, especially after pelvic
surgery. Bone infection, abscess and fistula near the symphysis can be
visualized with proper imaging, most frequently with MRI. For most patients
in this cohort surgical debridement combined with a minimum of 6 weeks
antibiotic treatment resulted in pain relief, improved walking ability and a
low recurrence rate.
What the heck is a choice rider? A theoretical framework and empirical model
Authors: Guerra Erick
Published: February 2022

As local, state, and federal agencies began investing substantial resources into subsidizing transit in the 1960s and ‘70s, public documents argued that transit agencies should focus on attracting choice riders instead of dependent riders, who have no alternatives and use transit regardless of service quality. After six decades, the definitions, uses, and implications of the terms choice and dependent rider have remained consistent in the academic and professional literature. These definitions, however, lack a strong theoretical grounding or empirical evidence to support them. Using travel diary data from the Philadelphia region, I estimate discrete choice models to identify choice riders, who I define as those who have close to a 50% probability of choosing between a car or transit for a given trip. The Philadelphia region, which has a diverse range of transit users and transit services, is an ideal place to develop and fit an empirical model of choice ridership. Attributes assumed to be associated with dependent riders, such as lack of a car, low income, and being a racial or ethnic minority, are much more prevalent among choice riders than the general metropolitan population. Choice riders are also diverse, with a mix of racial backgrounds, income levels, educational attainment, and access to private cars. Transit dependency, by contrast, is rare. The lowest and highest income residents generally only choose transit when service quality is high, and transit is cost and time competitive with the car.
Da educação 1.0 à educação 3.0: desafios para a prática docente no Século XXI

Este artigo tem por objetivo analisar as percepções de estudantes da graduação acerca do uso de plataformas online como ambiente colaborativo de aprendizagem e sua relevância para os processos formativos em moldes da Educação 3.0. Trata-se de um recorte de uma dissertação de mestrado em Educação na área de tecnologia e educação, que teve como prática de pesquisa o uso de redes sociais como ambiente de aprendizagem, desenvolvida na disciplina Português Instrumental, do curso de graduação em Letras Vernáculas de uma universidade federal. A pesquisa, de abordagem qualitativa, teve por sujeitos os dezessete estudantes da disciplina e foi realizada através do método da Pesquisa-formação, utilizando como instrumentos de coleta de dados a observação participante, o questionário e a entrevista semiestruturada, esta última realizada apenas com os alunos licenciandos da turma. Os dados evidenciaram a necessidade de se refletir sobre as práticas necessárias à docência na atualidade, destacando, com base nos depoimentos dos participantes, a ausência na formação inicial de atividades e práticas mais dinâmicas, em que haja uso efetivo das tecnologias, o que culmina em insegurança em relação aos desafios futuros. Se o estudante está em processo de formação, independentemente dos destinos profissionais escolhidos, é preciso atrelar o ensino às práticas que se fazem na sociedade informatizada e interconectada em que vivemos.

Croiser l’évaluation de compétences didactiques et numériques sur un même support : Un défi à relever dans un enregistrement vidéo (curriQvidéo) en Master Enseignement Éducation et Formation du premier degré
Authors: Faller Christine , Heiser Laurent
Published: February 2022

Cet article porte sur une recherche-action menée auprès d’étudiants professeurs du master enseignement éducation et formation (MEEF) de l’Inspé de l’université Côte d’Azur, parcours professeurs des écoles. Il s’agit de leur faire produire une vidéo narrant le déroulé d’une séquence ou d’un projet pédagogique dans la classe dans laquelle ils sont en alternance (3 semaines en classe et 3 semaine à l’Inspé). Cette production permet l’évaluation de 2 modules de leur master et semble, d’après les premiers résultats, constituer à la fois, un objet de formation et un outil d’évaluation. La commande de leurs formateurs : s’inscrire dans une démarche de pédagogie active et placer leurs élèves en situation de techno-créativité.

Dans le cadre d’un balado, une conseillère pédagogique et une chercheuse en évaluation posent des questions à une formatrice sur son expérience de conception d’une situation d’évaluation par les pairs effectuée lors d’un cours de deuxième cycle en éducation se déroulant à distance en mode asynchrone. Cette réflexion constructive à trois voix et cette triangulation des praxéologies de formation ont permis l’analyse de la pratique évaluative et de ses retombées sur l’expérience étudiante et les apprentissages acquis. Les constats tirés de cet échange sont présentés de manière à mettre en lumière les bénéfices et les limites de l’évaluation par les pairs à l’aide du numérique afin de favoriser sa mise en place dans d’autres contextes en enseignement supérieur.

The present study aimed to evaluate the impact of industrial processing (neutralization/degumming, bleaching, and deodorization) on physicochemical characteristics of soybean oil and soybean oil deodorizer distillate (SBO-DD) collected from two different industries. The substantial impact of processing was observed on all physicochemical parameters except the iodine value (IV) and saponification value (SV). Gas chromatography-flame ionization detector (GC-FID) and Gas chromatography-mass spectrometry (GC-MS) analytical techniques were used for the quantification of individual fatty acids, sterols, and 3-monochloropropane diol (3-MCPD) ester. Among the fatty acids, palmitic and linoleic acids were present at higher concentrations in all processing stages. Among sterols, β-sitosterol was found to be higher (25.65 and#181;g/g) in crude soybean oil and reduced to 16.44 and#181;g/g after processing till the final deodorization stage. 3-MCPD ester was developed during the neutralization/degumming process and further increased during bleaching and deodorization up to 315 and#181;g/kg, respectively. SBO-DD was found to be a rich source of total and individual sterols as compared to crude or processed soybean oil. High free fatty acid (FFA) level in deodorizer distillate indicated that SBO-DD is a potential source of biodiesel production.
