Caminhando pela Psicanálise
Authors: Favilli Myrna Pia
Published: February 2022

A autora nos oferece neste livro uma verdadeira viagem existencial e psicanalítica!Seu campo inicial de formação é a filosofia, na sua querida Maria Antônia, então sede da FFCL-USP, que lhe ofereceu sólido terreno para reflexão e consciência política. Considera que o fundamental para um psicanalista é sua liberdade de pensamento, sua criatividade e sua capacidade de dedicação. Propõe a diversidade teórica nos institutos de formação, para dar conta da complexidade da mente humana, enfatizando a importância da intuição e do sonho para que se possa “tocar o fundo da alma”. Partindo das lembranças infantis, ela penetra primeiramente no universo da análise de crianças, sua “porta de entrada”, após um curso de especialização em Psicologia Clínica na USP. Dedica-se às “tragédias precoces” observadas nas crianças muito comprometidas no desenvolvimento emocional. A análise de crianças e de adolescentes vai permanecer como elemento fundamental de sua identidade psicanalítica. A autora nos mostra como a clínica ultrapassa em muito as teorias, colocando a necessidade de evitar o que chama de formatação e recomendando uma correlação possível de teorias, que se integram em sua mente de maneira pessoal e original. Ressalta a importância da dimensão temporal no processo analítico, de um término, ou seja, de uma análise que não se prolongue eternamente: "lidar com os resíduos transferenciais, criando uma originalidade de pensamento” e proporcionando “o reconhecimento de um núcleo original, próprio de cada paciente”.Ana Maria Stucchi Vannucchi Membro efetivo e analista didata da SBPSP

O Infantil na Psicanálise: Memória e temporalidades
Authors: Tanis Bernardo
Published: February 2022

Nesta obra, que agora ganha sua segunda edição, o psicanalista Bernardo Tanis convida o leitor a transitar pelas multifacetadas dimensões da memória e da temporalidade que nos habitam e conferem sentido à nossa existência – e a descobrir por que o infantil, como fonte de desilusão ou de inspiração, nunca deixa de ser referência. O infantil é o testemunho inconsciente, atual e vivo da realidade psíquica e da constituição da nossa subjetividade. Para além de uma dimensão onipotente e por vezes traumática, expressa o potencial pulsional e criativo da nossa singularidade. “Transformar a relação com o infantil não significa sua eliminação, mas permitir uma reorganização de forças para que o novo possa advir”.
Tempos de Encontro: Escrita, escuta, psicanálise
Authors: Volich Rubens M.
Published: February 2022

Este livro é um tributo aos encontros e à memória. Modelado pela escuta, pela escrita e pela psicanálise, evoca pessoas queridas que me provocaram, me tocaram e me constituíram. Os textos destacam a importância da dimensão coletiva, social e política da psicanálise e a relevância da alteridade para a constituição do sujeito e para a ética clínica e institucional. Neles, discuto os processos de subjetivação que articulam corpo e mente, o enquadre e a relação terapêutica, o processo educativo e a prática médica e a transmissão em psicanálise. Em tempos de acentuado esgarçamento das relações pessoais e sociais, é ainda mais fundamental lembrar que nada disso teria sido possível sem a experiência dos encontros. Este livro celebra essas experiências e minha gratidão a todos que delas participaram.
Identidades Visuais Flexíveis: Das origens ao projeto
Authors: Silva Junior Jair Alves da
Published: February 2022

As marcas são parte indissociável de nosso cotidiano. A identidade visual, a expressão mais tangível da marca, é classicamente caracterizada por estabilidade, uniformidade, fácil identificação e reconhecimento. Seria ainda mandatória essa rigidez mesmo em um mundo cada vez mais dinâmico, globalizado e tecnológico? Caracterizadas pela flexibilidade, adaptação e dinamismo, as identidades visuais flexíveis são um contraponto a esse modelo? Este livro contribui para uma reflexão sobre o tema, ainda pouco discutido no Brasil, trazendo uma proposta de definição, terminologia e categorização dessas identidades visuais. A partir dessas definições, são abordados aspectos históricos das identidades visuais convencionais e casos em que estas se mostram mais flexíveis. Por fim, a obra aborda alguns estudos de caso que auxiliam na compreensão das particularidades de processo e de projeto, apontando para novas possibilidades no campo do design.

Published: February 2022

The new immunosuppressive drug Leflunomide has been used in the treatment of rheumatoid arthritis recently. By its efficiency Leflunomide is not inferior to the long known basic drug - Methotrexate. In most cases, Leflunomide is well tolerated. However, it can cause severe side effects in some patients. The most common adverse effects of Leflunomide are gastrointestinal disorders, weight loss, hypertension, skin infections, neuro-and hematotoxicity. Long-term therapy with Leflunomide has hepatotoxic and teratogenic effects. In 2010, the Food and Drug Administration (FDA) recommended to label the drug as a «black box» in the instructions, which means that clinical studies have shown that Leflunomide has a significant risk for serious and even life-threatening side effects.

Authors: Kapustinskaya O. A.
Published: February 2022

Objective: to determine the level of nosologic forms of hypertension disease (HD) in the population resettled from the Chernobyl exclusion zone to show its dependence on age, sex and the period of time the people lived in the zone before the resettlement. Material and methods. The data on the age of the cohort at the time of the accident were studied over 1988-2010 (30779 people at the age 18-39, 24343 people at the age 40-60). The research included epidemiological and statistical methods. Results. The post-accident period is characterized by the increased prevalence of cardiovascular diseases. The people whose age at the time of the accident was 18-39 detected the highest morbidity rate 17-22 years after the accident, and the people aged 40-60 at the time of the accident detected a high morbidity rate for the first time 6 years later and the maximum rate was 12-17 years later. The HD morbidity rate in the people whose age was 18-39 with the exception of the first period after the disaster was slightly higher than in the people from the older age group. During the first two accident periods, the patients diagnosed with essential HD were prevalent, which can be explained by the impact of stress and social and economic factors. Beginning from the third period, the morbidity of HD, mainly affecting the heart, has become more substantial and remained its high rate.

Published: February 2022

Objective: to study acquired and congenital (protein C level) risk factors for development of postoperative venous thrombosis in patients having phlebothrombosis in their past history. Material and methods. The subject of the study was patients (n = 32) with surgical pathology having episodes of pulmonary embolism and/or deep vein thrombosis of the lower limbs in their anamnesis. Congenital and acquired risk factors for venous thrombosis were analyzed in all the patients. We studied the following acquired risk factors: the patients′ age, obesity, varicosity of legs, diabetes mellitus, chronic lung diseases, cancer, smoking, previous trauma and surgery, long-term immobilization and also estro- and gestagenic contraceptives in women. The level of protein C was studied as an inherited factor causing phlebothrombosis. We also included some additional criteria such as early heart failure and stroke (under 45), complications of pregnancy, central vein catheterization, liver diseases, atherosclerosis of cardiac vessels and lower limbs, arterial hypertension into the list of the important risk factors. Results. The most frequent acquired risk factors were arterial hypertension (75 % of the cases), varicose veins (63 %), obesity (56 %), atherosclerosis (44 %), and diabetes mellitus (38 %). Chronic lung and liver diseases, fractures of shin bones, smoking, early infarction and strokes, complications of pregnancy, cancer were detected in the patients less often (6-31 % of the cases). Two thirds of the patients having cases of venous thrombosis revealed the deficient level of natural anticoagulant - protein C: 44 (39; 48) %. Conclusion . The detection of the acquired risk factors and especially the determination of the protein C level in blood serum in patients preparing for surgery is sufficient to be used as screening tests to assess the risk for the development of venous thrombosis.

The article presents a clinical case of treatment of a 57-year old patient with acute myocardial infarction of the left ventricular posterior wall complicated by ventricular fibrillation, cardiogenic shock, and respiratory distress syndrome. During the monitor control of the patient`s state, invasive hemodynamic monitoring according to PiCCO technology was additionally used. The complex treatment of the patient involved the application of inotropic and vasopressor drugs, maintaining of fluid balance, artificial lung ventilation. Results. Daily repeated control over central hemodynamics parameters for five days made it possible to apply inotropic and vasopressor drugs differentially, which led to the stabilization of hemodynamics. When the patient was disconnected from the artificial lung ventilation, his venous and arterial blood were tested. To be completely disconnected the patient had to undergo respirator tracheostomy. The patient was discharged in a satisfactory condition on the thirty-second day. Two months later, the patient`s quality of life was assessed by the questionnaire EQ-5D as good. Conclusion. The application of invasive hemodynamic monitoring in myocardial infarction complicated by cardiogenic shock favors the choice of the optimal treatment tactics. Repeated control over central hemodynamic parameters makes it possible to predict the course of the illness.

Abstract. The Tibetan Plateau is generally considered to be a significantly clean area owing to its high altitude; however, the transport of atmospheric pollutants from the Indian subcontinent to the Tibetan Plateau has influenced the Tibetan environments. Nyingchi is located at the end of an important water vapor channel. In this study, continuous monitoring of gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM), and particle-bound mercury (PBM) was conducted in Nyingchi from 30 March to 3 September 2019, to study the influence of the Indian summer monsoon (ISM) on the origin, transport, and behavior of Hg. The GEM and PBM during the preceding Indian summer monsoon (PISM) period (1.20±0.35 ng m−3 and 11.4±4.8 pg m−3 for GEM and PBM, respectively) were significantly higher than those during the ISM period (0.95±0.21 ng m−3, and 8.8±6.0 pg m−3); the GOM during the PISM period (13.5±7.3 pg m−3) was almost at the same level as that during the ISM period (12.7±14.3 pg m−3). The average GEM concentration in the Nyingchi region, obtained using passive sampler, was 1.12±0.28 ng m−3 (from 4 April 2019 to 31 March 2020). The GEM concentration showed that the sampling area was very clean compared to other high-altitude sites. The GEM has several patterns of diurnal variation during different periods. Stable high GEM concentrations occur at night and low concentrations occur in the afternoon during PISM, which may be related to the nocturnal boundary layer structure. High values occurring in the late afternoon during the ISM may be related to long-range transport. Low concentrations of GEM observed during the morning
in the ISM may originate from vegetation effects. The results of the
trajectory model demonstrate that the sources of pollutants at Nyingchi are
different with different circulation patterns. During westerly circulation
in the PISM period, pollutants mainly originate from central India, northeastern India, and central Tibet. During the ISM period, the pollutants mainly originate from the southern part of the SET site. The strong precipitation
and vegetation effects on Hg species during the ISM resulted in low Hg
concentrations transmitted to Nyingchi during this period. Further,
principal component analysis showed that long-distance transport, local
emissions, meteorological factors, and snowmelt factors are the main factors affecting the local Hg concentration in Nyingchi. Long-distance transport factor dominates during PISM and ISM3, while local emissions is the major contributor between PISM and ISM3. Our results reveal the Hg species distribution and possible sources of the most important water vapor channel in the Tibetan Plateau and could serve as a basis for further transboundary transport flux calculations.

Abstract. Atmospheric observations in remote locations offer a possibility to explore trace gas and particle concentrations in pristine environments. However, data from remote areas are often contaminated by pollution from local sources. Detecting this pollution is thus a central and frequently encountered issue. Consequently, many different methods exist today to identify local pollution in atmospheric composition measurement time series, but no single method has been widely accepted. In this study, we present a new method to identify primary pollution in remote atmospheric datasets, e.g., from ship campaigns or stations with low background signal compared to the pollution signal. The Pollution Detection Algorithm (PDA) identifies and flags periods of polluted data in five steps. The first and most important step identifies polluted periods based on the gradient (time-derivative) of a concentration over time. If this gradient exceeds a given threshold, data are flagged as polluted. Further pollution identification steps are a simple concentration threshold filter, a neighboring points filter (optional), a median and a sparse data filter (optional). The PDA only relies on the target dataset itself and is independent of ancillary datasets such as meteorological variables. All parameters of each step are adjustable so that the PDA can be “tuned” to be more or less stringent (e.g., flag more or less data points as polluted). The PDA was developed and tested with a particle number concentration dataset collected during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition in the Central Arctic. Using strict settings, we identified 62 % of the data as influenced by local pollution. Using a second independent particle number concentration dataset also collected during MOSAiC, we evaluated the performance of the PDA against the same dataset cleaned by visual inspection. The two methods agreed in 94 % of the cases. Additionally, the PDA was successfully applied on a trace gas dataset (CO2), also collected during MOSAiC, and on another particle number concentration dataset, collected at the high altitude background station Jungfraujoch, Switzerland. Thus, the PDA proves to be a useful and flexible tool to identify periods affected by local pollution in atmospheric composition datasets without the need for ancillary measurements. It is best applied to data representing primary pollution. The user-friendly and open access code enables reproducible application to a wide suite of different datasets.

The Impact of Environmental Variables on UAS-based Atmospheric Carbon Dioxide Measurements
Authors: B. H. de Azevedo Gustavo , Doyle Bill , Fiebrich Christopher A. , Schvartzman David
Published: February 2022

Abstract. This article assesses the individual impact of pressure, temperature, and humidity on the accuracy of atmospheric CO2 measurements collected by Unmanned Aerial Systems (UAS) using low-cost commercial Non-Dispersive Infrared sensors (NDIR). We build upon previous experimental results in the literature and systematically increase the variation range for each environmental variable to match the abrupt changes found in UAS vertical profiles. As a key contribution, we present a low-cost benchtop correction procedure to mitigate the impact of these variables and considerably improve the accuracy of CO2 measurements to be within ±2.5 ppm. Our findings support the use of low-cost NDIR sensors for UAS-based atmospheric CO2 measurements as a complementary in-situ tool for many scientific applications.
HBIM AND THEMATIC MAPPING: PRELIMINARY RESULTS
Authors: Delpozzo D. , Treccani D. , Appolonia L. , Adami A. , Scala B.
Published: February 2022

Abstract. Geomatics' interest in Building Information Modelling (BIM) processes applied to Cultural Heritage is evolving in many directions. The traditional fields of Geomatics -data acquisition and processing- have been largely dealt with about HBIM (Historical Building Information Modelling) systems, but there are still some issues that need to be explored in more detail. In addition to modelling, it is essential to consider the information content of the model, how it is generated, recorded and managed.If the objective of the HBIM model is the conservation project, it becomes essential to understand what types of data can be inserted in the model, how to record them and, above all, what their purpose is. The HBIM approach did not start out as a simple data repository, but as an information tool with the aim of helping the designer at all stages of the construction process. Moving to the field of preservation, much information about the building is represented by thematic maps. They allow to have a graphical image of the state of conservation of a façade or to understand the structural situation of a building.This research, tested on the Arch of Augustus in Aosta, starts from the big amount of data acquired by the RAVA Laboratory of the Superintendency of Aosta during a long period. These data allowed to test different approaches to thematic mapping, according to the specific themes to be represented (previous restoration interventions, diagnostics, decay mapping, etc). Anyway, this experiment also required a theoretical reasoning that preceded the operational phases. Faced with a new system, in fact, it is always advisable to reason about the method applied, to avoid the error of simply translating a method that could instead be developed in new directions. The question, to which this article wants only to begin answering, concerns the role of thematic mappings in the preservation design made by a HBIM approach, their necessity and their implementation towards a truly three-dimensional data, which thus maintains all the information that is acquired directly in three dimensions and which instead, today, are reprojected in 2D or used as a placeholder in the 3D space.

Authors: Nocerino E. , Menna F. , Verhoeven G. J.
Published: February 2022

Abstract. Image stabilisation (IS) is a family of approaches whose aim is to reduce motion blur in still images and shaking effect in video frames. A variety of techniques are currently implemented in cameras and camcorders: some involve hardware solutions, other are software approaches. In general, IS for still photography entails hardware in-camera or in-lens solutions. Video stabilisation, on the other hand, can be accomplished with software algorithms, either in real-time within the camera or in post-processing.Whereas IS aids photography and video making, its influence on the photogrammetric 3D modelling process has not been investigated. This article addresses this aspect. To this purpose, several laboratory and real-world tests were carried out, whose results showed that IS must be disabled when accuracy matters in photogrammetric projects. Details are provided in the manuscript.
HANDHELD FISHEYE MULTICAMERA SYSTEM: SURVEYING MEANDERING ARCHITECTONIC SPACES IN OPEN-LOOP MODE – ACCURACY ASSESSMENT
Authors: Perfetti L. , Fassi F.
Published: February 2022

Abstract. The task of digitalizing meandering complex spaces in 3D is a challenging one even with the most advanced instrumentation like lightweight terrestrial laser scanner or portable/wearable Mobile Mapping Systems (MMSs). The complexity and extension of architectonic spaces such as staircases, corridors and passages are such that the acquisition time using static devices becomes prohibitive and the accuracy using mobile devices gets affected by drift error leading to warped models or requiring abundant control measurements. This paper presents a photogrammetric portable fisheye multicamera solution for the 3D survey of complex areas that aims at being both handy and fast in the acquisition as well as more reliable ad accurate than common MMSs. The paper showcases a stress test conducted on five complex reconstruction trajectories selected from the meandering connection passages of Milan’s Cathedral. The tests are constructed as worst-case scenario to evaluate the accuracy and drift error amount of the proposed system in open-ended unconstrained paths. The results, though still suffering from moderate drift error, highlights the potential of the solution, especially in retaining the overall shape and orthogonality of the architectonic elements acquired.
GEOMETRIC ANALYSIS OF A SPACE GRID STRUCTURE BY AN INTEGRATED 3D SURVEY APPROACH
Authors: Russo M. , Russo V.
Published: February 2022

Abstract. The survey and modeling of spatial grid structures is often a challenging task to solve, due to the many bottlenecks present in the reverse modelling process. Geometrical and material complexity, scale variation, shadows effects, low accessibility, mismatch between similar elements, metrical validation, data management are all critical passages. They must be solved to obtain a reliable data able to solve the system maintenance and intervention requirements. In these cases, in particular, when the structure is difficult to be accessed, it is essential to plan an integrated survey approach. This paper shows how the survey and modelling of an impressive structure was carried out using both TLS and RPAS photogrammetry. After being validated, the data is integrated into a single point cloud that completely describes the structure, eliminating shadow areas and hidden parts. In the modeling process, particular attention was paid to verifying the correspondence between as-built and project. Finally, an element of particular interest is represented by the attempt to recognize the individual construction components belonging to specified geometric and dimensional classes, with the advantage of obtaining a complete model that is as faithful as possible to the real situation of the structure.
AR AND VR FOR ENHANCING MUSEUMS’ HERITAGE THROUGH 3D RECONSTRUCTION OF FRAGMENTED STATUE AND ARCHITECTURAL CONTEXT

Published: February 2022

Abstract. This paper presents the results of multidisciplinary research in which reconstructive digital modelling operates on different areas of heritage and at different scales to realize an analysis, interpretation, and communication experience in the field of museum valorization. It is, in fact, a work that includes both the philological reconstruction of the lost parts of a Buddha statue of Gandhāra, dating back to the second century b.C. and kept at the Museum of Oriental Art (MAO) in Turin, and its contextualization within a coeval architectural complex, recognized as philologically compatible, located in Balo-Kale, in the region of Gandhāra. The reconstructive models are finally used with communicative purposes for augmented reality (AR) and virtual reality (VR) applications inside the museum.
AUTOMATIC STRUCTURING OF PHOTOGRAPHIC COLLECTIONS FOR SPATIO-TEMPORAL MONITORING OF RESTORATION SITES: PROBLEM STATEMENT AND CHALLENGES

Published: February 2022

Abstract. Over the last decade, a large number of digital documentation projects have demonstrated the potential of image-based modelling of heritage objects in the context of documentation, conservation, and restoration. The inclusion of these emerging methods in the daily monitoring of the activities of a heritage restoration site (context in which hundreds of photographs per day can be acquired by multiple actors, in accordance with several observation and analysis needs) raises new questions at the intersection of big data management, analysis, semantic enrichment, and more generally automatic structuring of this data. In this article we propose a data model developed around these questions and identify the main challenges to overcome the problem of structuring massive collections of photographs through a review of the available literature on similarity metrics used to organise the pictures based on their content or metadata. This work is realized in the context of the restoration site of the Notre-Dame de Paris cathedral that will be used as the main case study.
VISUAL CROSS-EXAMINATION OF ARCHITECTURAL AND ACOUSTIC DATA: THE 3D INTEGRATOR EXPERIMENT

Published: February 2022

Abstract. This paper presents an online application called 3D integrator enabling visual cross-examinations of architectural and acoustic data on web browsers, and explains the rationale behind its development. The tool consists of a series of overlays developed over the Potree 3D point cloud renderer. The 3D integrator is used to display visually, in an interactive environment, the 3D point clouds resulting from a survey protocol tailored to the specific needs of the corpus under scrutiny – fifteen small scale edifices often referred to as “minor heritage assets - and to the research’s overall ambition, co-reasoning on architectural and acoustic features at an interdisciplinary level. One of the tool’s distinctive features is to project abstract information (acoustic indicators) in a “close to real” 3D space (point clouds), hence merging scientific visualisation and information visualisation practices. The paper shortly sums up the particularities of the survey protocol, and discusses in detail the implementation of the analytical add-ons that have been introduced (visual trace of the survey protocol itself, exploitation of panoramas, volume calculation, and exploratory 3D representation of acoustic indicators). Finally, early uses of the tool are summarised and the services it actually offers at this stage are commented.

Abstract. Nowadays professionals from the Cultural Heritage field make use of Digital technology in all its diversity as a tool to conduct various type of work: archeological and architectural survey, monitoring, conservation programs, historic researches. This paper describes the first steps of a PhD research aiming at exploring the use of analog photographs from the French-Egyptian center for the study of Karnak Temples (CFEETK) in photogrammetry. The goal is to compare previous condition state of monuments in the 20th century with their contemporary condition and to introduce 3D model in correlation databases. The paper presents the context of the study and the complex of Karnak temples then the set of archives photographs that are used and how they are processed. At this stage, sets of analog photographs from the White Chapel were used in Agisoft Metashape combined with contemporary photographs to provide visuals from the condition of the monument after its restoration in 1985.

Published: February 2022

Abstract. In order to improve the accuracy and efficiency of special machining for a complex surface, a 2RPU-2SPR (where R, P, U, and S stand for revolute,
prismatic, universal, and spherical joints, respectively) over-constrained redundantly actuated parallel robot mechanism is proposed. And six performance evaluation indexes are established to ensure the working performance including workspace, motion/force transmission efficiency, stiffness, dexterity, energy efficiency, and the inertia coupling index. Furthermore, a collaborative optimal
configuration algorithm is conducted based on an orthogonal experimental design algorithm and a multi-objective particle swarm optimization algorithm. On the basis given above, a simulation analysis of a multi-objective optimization is conducted. Compared with two traditional, intelligent optimization algorithms of a multi-objective particle swarm optimization algorithm and an orthogonal experimental design method, the improved collaborative multi-objective optimization algorithm has a better optimization effect.
