Identification of vaccine candidate proteins in Ureaplasma urealyticum causing infertility
Authors: Shiragannavar Shilpa Jeevappa , Madagi Shivakumar B.
Published: July 2021

Background:

Ureaplasma urealyticum has gained resistance to number of antibiotics and has been of the greatest concerns nowadays. The treatment options remain extremely low due to the increased levels of intrinsic resistance gained by the pathogen.

Aim:

The present study focuses on designing a peptide-based vaccine as there is no vaccine available for the pathogen.

Materials and Methods:

All the protein sequences of pathogen were collected and examined using various in silico methods to identify the most immunogenic proteins. The study identifies the proteins which are antigenic in nature which induce the immune response, which lends to quick response of immune system on reinfection. The study describes peptide-based vaccine against U. urealyticum using molecular docking and molecular dynamics simulation approach.

Results:

The study identifies novel putative vaccine candidate proteins that are antigenic, membrane bound and non-allergenic.

Conclusion:

The results of the study imply that the vaccine candidate proteins identified may bring about vigorous enduring defensive immunity against U. urealyticum.

Authors: Saikia Uma K. , Jabbar P. K. , Das Darvin V.
Published: July 2021

Background:

Endogenous sex hormones and sex hormone-binding globulins (SHBG) determine the risk of occurrence of Type 2 diabetes mellitus (T2DM) in postmenopausal (PM) women.

Aims:

To investigate the association between sex hormones (estradiol and testosterone) and SHBG with plasma glucose, fasting insulin levels, HbA1c, and homeostasis model assessment insulin resistance (HOMA-IR) and also to investigate independent role of sex hormones in the occurrence of T2DM among PM.

Settings and Design:

Cross-sectional case–control study.

Subjects and Methods:

The present study was conducted in Endocrinology department Guwahati, Medical College, Assam, India. The participants included cases – PM women with T2DM (n = 100) and controls – Healthy PM women (n = 86). The medical history, clinical examination, and investigations including total testosterone, serum estradiol, SHBG, free testosterone index, high sensitivity C-reactive protein (hs-CRP), lipid profile, fasting insulin, fasting plasma glucose (FPG), and postprandial plasma glucose (PPPG) were done and analyzed. HOMA-IR was calculated.

Statistical Analysis:

Pearson correlation between sex hormone level and SHBG with plasma glucose, HbA1c, fasting insulin, hs-CRP, and HOMA-IR was seen. Multivariance logistic analysis was done to find the independent association between sex hormones/SHBG and the occurrence of T2 DM. P < 0.05 was considered statistically significant.

Results:

Among the cases, a significant positive correlation was found between total testosterone/free testosterone index with waist circumference, FPG PPPG, HbA1c, fasting insulin, and HOMA-IR, and a significant negative correlation was found between SHBG and FPG, PPPG, HbA1c, fasting insulin, and HOMA-IR (P < 0.01). The logistic analysis showed total testosterone levels and SHBG are independently associated with the occurrence of T2 DM among PM (P < 0.01).

Conclusion:

SHBG and testosterone levels in PM can be a risk marker for the development of T2DM.
Hematuria – Look beyond the Urinary Tract – A Rare Case Report
Authors: Bansal Rohit , Bansal Priya
Published: July 2021

The major causes of hematuria in a middle-aged female include infections, renal calculi, or structural abnormalities of the urinary tract. Most patients are investigated and treated on an outpatient basis. While a possibility of malignancy of the bladder or kidneys may also be considered, hematological malignancy is an uncommon cause of hematuria. Detailed evaluation is important to rule out malignancy in new-onset hematuria. We report a case of a 49-year-old female who presented with gross hematuria, later diagnosed to have multiple myeloma (MM), despite the absence of its classical symptoms. This unusual presentation reaffirms its status as “The Great Masquerader.” The case is worth highlighting because gross hematuria as the first presentation of MM is uncommon. The author wishes to stress that the clinician should also suspect blood dyscrasias with associated coagulation abnormalities in the workup of gross hematuria.
Pelvic Floor Disorders among Gynecological Cancer Survivors in Sub-urban Regions of Kanchipuram District–India
Authors: Sureshbabu M. Anbupriya , Abirami P. S.
Published: July 2021

Background:

Pelvic floor muscle is the group of muscles: layering down the pelvic region; Controlling the bowel movements, urination, and sexual intercourse; working in a balanced and coordinated contraction and relaxation. The inability to control the pelvic floor muscles leads to pelvic floor disorders like urinary incontinence, faecal incontinence, dyspareunia, and pelvic pain.

Objective:

The aim of this study is to find the prevalence of pelvic floor disorders among gynaecological cancer survivors in sub-urban regions of Kanchipuram district, India.

Materials and Methods:

This study employs a nonexperimental study design. The procedure is well explained and informed consent is obtained from the gynaecological cancer survivors based on the inclusion and exclusion criteria. Gynecological cancer survivors who are not under any treatments for the last 1 year has been considered for this study. There were two sets of questionnaires in which one depicts vulvar pain function (Vulvar Pain Functional Questionnaire) and the other relates to pelvic floor symptom botheration (Pelvic Floor Bother Questionnaire). The individual has given enough time to fill the questionnaire. Patients seem necessary are further referred to the outpatient physiotherapy department.

Results:

A moderate amount of Pelvic pain was reported to be felt by at least 64.6% of survivors. Added to it, a moderate level of bothersome was found to be reported by at least 56.2 % of survivors.

Conclusion:

Findings conclude that there is a higher prevalence of pelvic floor dysfunction among gynecological cancer survivors.
Enhanced Recovery after Surgery
Authors: Gupta Sandhya , Rane Ajay
Published: July 2021

Enhanced recovery after surgery (ERAS) is a multimodal convention first reported for colorectal and gynecologic procedures. The main benefits have been a shorter length of stay and reduced complications, leading to improved clinical outcomes and cost savings substantially. With increase in life expectancy, recent years has shown a significant rise in advanced age population, and similarly, a rise in age-related disorders requiring surgical management. Due to pathophysiological and metabolic changes in geriatric age group with increased incidence of medical comorbidities, there is higher risk of enhanced surgical stress response with undesirable postoperative morbidity, complications, prolonged immobility, and extended convalescence. The feasibility and effectiveness of ERAS protocols have been well researched and documented among all age groups, including the geriatric high-risk population.[1] Adhering to ERAS protocols after colorectal surgery showed no significant difference in postoperative complications, hospital stay, or readmission rate among various age groups.[2] A recent report mentions the safety and benefits following ERAS guidelines with reduced length of stay in elderly patients with short-level lumbar fusion surgery.[3] The concept of prehabilitation has evolved as an integral part of ERAS to build up physiological reserve, especially in geriatric high-risk group, and to adapt better to surgical stress.[4] High levels of compliance with ERAS interventions combined with prehabilitation can be achieved when a dedicated multidisciplinary team is involved in care of these high-risk patients.
Genitourinary Syndrome of Menopause Assessment Tools
Authors: Mension Eduard , Alonso Inmaculada , Tortajada Marta , Matas Isabel , Gómez Sílvia , Ribera Laura , Ros Cristina , Anglès-Acedo Sònia , Castelo-Branco Camil
Published: July 2021

New therapeutic options are being considered to treat genitourinary syndrome of menopause (GSM), such as vaginal laser, ospemifene, or prasterone, but there is no explicit agreement in the scientific community for its use. Some concerns have arisen on how to evaluate the improvement of GSM symptoms. In 2003, the FDA suggested possible end points for this purpose: change in severity of symptoms, change in vaginal pH, and change in vaginal maturation index (VMI). Contrarily, the most common assessment tools used to quantify severity and improvement of GSM nowadays are the visual analog scale of GSM symptoms, the vaginal health index, and the female sexual function index. In our opinion, subjective and objective variables to evaluate GSM can be differentiated, and not many of the considered objective outcomes are used in the recent literature assessing GSM. There is the possibility that some therapies present only subjective improvement, giving place to a possible placebo effect that is not being evaluated. To conclude, there is a demand to evaluate whether vaginal pH and VMI are enough to assess objectively GSM changes or new objective approaches should be audited.

Authors: Kaur Tanudeep , Kumari Rajesh , Sharma J. B. , Pandey Kavita , Uppal Bharti , Deb Koushik Sinha
Published: July 2021

Background:

Urinary incontinence (UI) presents in over 50% menopausal women affecting their quality of life leading to depression and hence needs addressal and treatment as very few of them seek medical help.

Aims:

Our aim was to determine the prevalence of depression, and the correlation of severity of UI with depression in incontinent women versus continent controls.

Methodology:

A cross-sectional case–control study of previously diagnosed 100 incontinent women (Stress/Urgency/Mixed) was done over a period of 3 months. The severity of UI was assessed on Patient Incontinence Severity Assessment (a form of Likert scale) and depression was assessed on a validated Patient Health Questionnaire-9 scale.

Statistical Analysis:

The statistical analysis was performed using SPSS version 19.0.

RESULTS:

Most of our cases were 51–60 years, with Urge UI being the most predominant (88%). Hundred percent of our incontinent patients were depressed, with 48% and 45% being severely and moderately severely depressed, respectively. A highly significant correlation was found between the severity of incontinence, amount of leakage, leaking pattern, and depression.

Conclusion:

All of our incontinent patients were depressed, with the severity of depression increasing with the severity of incontinence.
Experiential Pharmacy Education During a Pandemic: Lessons Learned
Authors: Early Nicole K. , Callas Andrea , Sarbacker G. Blair , Bouwmeester Carla J. , Bartucca Macayla A.
Published: July 2021

The COVID-19 pandemic has radically changed how the world operates and introduced a multitude of unprecedented challenges for all health professionals, especially for those responsible for training learners, including pharmacy residents and students. Due to density and social distancing
restrictions, many pharmacy schools and residency programs had to transition to virtual experiential learning‐with little to no existing literature, structure, or adequate time for planning. This article offers a variety of approaches to ensure that pharmacy learners meet accreditation
requirements, engage in interprofessional education and collaboration, reflect on their learning, prioritize self-care, and are adequately prepared to enter geriatric pharmacy practice despite current challenges with the COVID-19 pandemic. Authors address both challenges, as well as opportunities
to expand future experiential education for all pharmacy learners.
How a small virus changed our world and the special role of anosmia
Authors: Fokkens W.J.
Published: July 2021

In January 2020 we encountered the first news on a novel coronavirus (SARS-CoV-2) infecting the population of the Chinese city Wuhan and resulting for some patients in a potentially deadly pneumonia. Currently, coronavirus disease 2019 (COVID-19) is spreading rapidly around the globe. For many years we have been warned that we would face a new pandemic, most likely with a zoonotic virus. For COVID-19 it was shown that transmission can occur via droplets and aerosols that can remain in the air for some hours and also via contaminated surfaces. Extra risks have been suggested to exists for aerosol producing surgery in sinus- and skull-base surgery. Ongoing transmission is especially difficult to prevent when the pathogen can be transmitted during the incubation period before the patient experiences symptoms. In March, Claire Hopkins and colleagues warned the rhinologic community and later health authorities about the significant increase in anosmia (and dysgeusia) related to (often further) asymptomatic COVID-19 and pointed to the possibility of recognizing COVID-19 patients by unexplained anosmia without other symptoms.
Case Report: A Case of Tuberculosis with Psoriasiform Lichen Scrofulosorum Exhibiting Koebner’s Phenomenon followed by Scrofuloderma
Authors: Muradia Ishika , Khullar Geeti , Sharma Shruti , Kolte Sachin
Published: July 2021

Lichen scrofulosorum is the most common tuberculid in the Indian population and the second most common form of cutaneous tuberculosis. We discuss an uncommon presentation of lichen scrofulosorum, with psoriasiform morphology and koebnerization at tuberculin test site, associated with cervical lymphadenitis in a 17-year-old girl. Although the cutaneous lesions resolved completely after 3 months of antitubercular treatment (ATT), she developed scrofuloderma in the left cervical region at 4 months. In the absence of rifampicin resistance, ATT was continued for another 6 months, with no further evidence of disease activity. This case represents an infrequent occurrence of lichen scrofulosorum followed by scrofuloderma, which necessitated a prolonged course of first-line ATT.
The Impact of Culture on Learning Transfer in Burkina Faso and Ghana
Authors: Brion Corinne
Published: July 2021

Culture is a predominant force in people’s lives that impacts learning and thus culture influences learning transfer. Because working across nations has become the norm and every year billions of dollars are spent on professional learning around the world, it is crucial for organisations to understand the role culture plays in the learning transfer process. Using a multidimensional model of learning transfer and the six dimensions of national culture model as conceptual frameworks, this qualitative study used a case study approach to examine the impact of culture on learning transfer in Burkina Faso and Ghana, West Africa. Interviews were conducted with 20 principals who attended leadership professional learning in Ghana and Burkina Faso. Data collection also included observations and document analysis. Findings indicated that several cultural factors influenced learning transfer in these two nations in the areas of pretraining and follow-up. Based on these findings, the author offers recommendations.
Algorithms to get out of Boring Area Trap in Reinforcement Learning
Authors: Noulawe Tchamanbe Landry Steve , MELATAGIA YONTA Paulin
Published: July 2021

Reinforcement learning algorithms have succeeded over the years in achieving impressive results in a variety of fields. However, these algorithms suffer from certain weaknesses highlighted by Refael Vivanti and al. that may explain the regression of even well-trained agents in certain environments : the difference in variance on rewards between areas of the environment. This difference in variance leads to two problems : Boring Area Trap and Manipulative consultant. We note that the Adaptive Symmetric Reward Noising (ASRN) algorithm proposed by Refael Vivanti and al. has limitations for environments with the following characteristics : long game times and multiple boring area environments. To overcome these problems, we propose three algorithms derived from the ASRN algorithm called Rebooted Adaptive Symmetric Reward Noising (RASRN) : Continuous ε decay RASRN, Full RASRN and Stepwise α decay RASRN. Thanks to two series of experiments carried out on the k-armed bandit problem, we show that our algorithms can better correct the Boring Area Trap problem.

Les algorithmes d'apprentissage par renforcement ont réussi au fil des années à obtenir des résultats impressionnants dans divers domaines. Cependant, ces algorithmes souffrent de certaines faiblesses mises en évidence par Refael Vivanti et al. qui peuvent expliquer la régression des agents même bien entraînés dans certains environnements : la différence de variance sur les récompenses entre les zones de l'environnement. Cette différence de variance conduit à deux problèmes : le Piège de la Zone Ennuyeuse (Boring Area Trap) et le Consultant Manipulateur. Nous observons que l'algorithme Adaptive Symmetric Reward Noising (ASRN) proposé par Refael Vivanti et al. présente des limites pour des environnements ayant les caractéristiques suivantes : longues durées de jeu et environnement à zones ennuyeuses multiples. Pour pallier ces problèmes, nous proposons trois algorithmes dérivés de l'algorithme ASRN nommés Rebooted Adaptive Symmetric Reward Noi-sing (RASRN) : Continuous ε decay RASRN, Full RASRN et Stepwise α decay RASRN. Grâce à deux séries d'expérimentations menées sur le problème du bandit à k bras, nous montrons que ces algorithmes permettent de mieux corriger le problème du piège de la zone ennuyeuse.
A Nash-game approach to joint data completion and location of small inclusions in Stokes flow
Authors: Ouni Marwa , Habbal Abderrahmane , Kallel Moez
Published: July 2021

We consider the coupled inverse problem of data completion and the determination of the best locations of an unknown number of small objects immersed in a stationary viscous fluid. We carefully introduce a novel method to solve this problem based on a game theory approach. A new algorithm is provided to recovering the missing data and the number of these objects and their approximate location simultaneously. The detection problem is formulated as a topological one. We present two test-cases that illustrate the efficiency of our original strategy to deal with the ill-posed problem.

Nous étudions le problème de détection des petites inclusions immergées dans un fluide visqueux et incompressible, lorsque le mouvement de celui-ci est régi par les équations de Stokes. Des données du type Cauchy seront ainsi fournies seulement sur une partie frontière de l’écoulement.A cet égard, nous essayons de développer une méthode originale basée sur une approche de théorie des jeux, pour résoudre notre problème inverse. Un nouvel algorithme a été donc présenté traitant simultanément la question de la reconstruction des données manquantes avec celle de détection d’objets. La notion de gradient topologique a été utilisée afin de déterminer le nombre d’objets présents et leurs localisations approximatives. Dans cet objectif, une étude numérique présentée, a été effectuée pour prouver l’efficacité de la méthode.
The Complexity of Reachability in Affine Vector Addition Systems with States
Authors: Blondin Michael , Raskin Mikhail
Published: July 2021

Vector addition systems with states (VASS) are widely used for the formal
verification of concurrent systems. Given their tremendous computational
complexity, practical approaches have relied on techniques such as reachability
relaxations, e.g., allowing for negative intermediate counter values. It is
natural to question their feasibility for VASS enriched with primitives that
typically translate into undecidability. Spurred by this concern, we pinpoint
the complexity of integer relaxations with respect to arbitrary classes of
affine operations.
More specifically, we provide a trichotomy on the complexity of integer
reachability in VASS extended with affine operations (affine VASS). Namely, we
show that it is NP-complete for VASS with resets, PSPACE-complete for VASS with
(pseudo-)transfers and VASS with (pseudo-)copies, and undecidable for any other
class. We further present a dichotomy for standard reachability in affine VASS:
it is decidable for VASS with permutations, and undecidable for any other
class. This yields a complete and unified complexity landscape of reachability
in affine VASS. We also consider the reachability problem parameterized by a
fixed affine VASS, rather than a class, and we show that the complexity
landscape is arbitrary in this setting.
Presburger Arithmetic with algebraic scalar multiplications
Authors: Hieronymi Philipp , Nguyen Danny , Pak Igor
Published: July 2021

We consider Presburger arithmetic (PA) extended by scalar multiplication by
an algebraic irrational number $\alpha$, and call this extension
$\alpha$-Presburger arithmetic ($\alpha$-PA). We show that the complexity of
deciding sentences in $\alpha$-PA is substantially harder than in PA. Indeed,
when $\alpha$ is quadratic and $r\geq 4$, deciding $\alpha$-PA sentences with
$r$ alternating quantifier blocks and at most $c\ r$ variables and inequalities
requires space at least $K 2^{\cdot^{\cdot^{\cdot^{2^{C\ell(S)}}}}}$ (tower of
height $r-3$), where the constants $c, K, C>0$ only depend on $\alpha$, and
$\ell(S)$ is the length of the given $\alpha$-PA sentence $S$. Furthermore
deciding $\exists^{6}\forall^{4}\exists^{11}$ $\alpha$-PA sentences with at
most $k$ inequalities is PSPACE-hard, where $k$ is another constant depending
only on~$\alpha$. When $\alpha$ is non-quadratic, already four alternating
quantifier blocks suffice for undecidability of $\alpha$-PA sentences.
A Detailed Account of The Inconsistent Labelling Problem of Stutter-Preserving Partial-Order Reduction
Authors: Neele Thomas , Valmari Antti , Willemse Tim A. C.
Published: July 2021

One of the most popular state-space reduction techniques for model checking
is partial-order reduction (POR). Of the many different POR implementations,
stubborn sets are a very versatile variant and have thus seen many different
applications over the past 32 years. One of the early stubborn sets works shows
how the basic conditions for reduction can be augmented to preserve
stutter-trace equivalence, making stubborn sets suitable for model checking of
linear-time properties. In this paper, we identify a flaw in the reasoning and
show with a counter-example that stutter-trace equivalence is not necessarily
preserved. We propose a stronger reduction condition and provide extensive new
correctness proofs to ensure the issue is resolved. Furthermore, we analyse in
which formalisms the problem may occur. The impact on practical implementations
is limited, since they all compute a correct approximation of the theory.

Authors: Bozdo Rejla
Published: July 2021

During 2020, the world faced the unusual situation of COVID-19 infections outbreak and at the same time people and governments faced the changes in lifestyle that was forced by the measures taken to manage the crises. Measures as social and physical distancing, in addition to self-quarantine, have been imposed by governments worldwide. Education sector was affected by the measures. Students were out of school worldwide. Education moved to the online and remote learning, posing new challenges for students and teachers. The new lifestyle caused stress for many people al around the world, students included. This research aims to investigate students’ behavior during 2020 on the level of stress, desire to study, laziness and concentration and gender differences. Through a cross-sectional online survey among 254 students of higher education institutions in Albania, was found out that stress levels of students in higher education institutions were higher among female students compared to male students. The research shows that stress has negative correlation to the desire to study and concentration and positive correlation to laziness, while the desire to study has negative correlation to laziness and positive correlation to concentration. Through linear regression analysis, this study provides insights on the factors that have influenced students’ feelings during pandemic and what can be done for improvement.
Co-Designing Meaningful Dialogues on Sexual Harassment
Authors: Benbrahim Dina
Published: July 2021

We live in a dysfunctional world led by white-male dominated, patriarchal and capitalist societies that perpetuate continuous oppression. The public space is culturally perceived as a man’s world while women have been traditionally confined to the private one. Because claiming a safe public space for all is a political act, I want to actively cultivate a creative experience that facilitates dialogue, ideation and agency for self-identified women to reclaim their right to exist safely in it. My paper will focus on this creative experience, as a collective resistance, that started in Gainesville, FL at the Civic Media Center and has now become an ongoing, online and worldwide endeavour.
Disappearing Bodies, Disappearing Objects: What Years and Years Can Teach Us About Design
Authors: Pandelakis Saul
Published: July 2021

British television has recently acquired a reputation for producing challenging dystopian visions of the future. While Black Mirror casts a disenchanted look on our experiences, Years and Years lacks cynicism and, in that regard, holds interesting lessons for designers. While the issues commented on by the British fictional series are also global in scale and scope (nuclear bombing, political tensions in the EU, energy crisis), the series displays a rare creativity in its depiction of future objects and innovations. The inventions depicted can be truly groundbreaking, long awaited or dysfunctional. While the series examines these objects and dispositifs, it never leans towards a set position, be it discouraged Luddism or happy-go-lucky celebration. Because it refuses to embrace or reject technology, it gives space to a rich examination of the possible design products of the future. This essay examines three selected objects (a meal tray, a vocal AI and a drone) which potentially condense a great deal of the current criticism of technology. None of the analysed objects are incredible in form or function; in fact, they have all been the subject of previous fiction matter. These objects will be analysed in terms of dispositifs and usage, but also as temporal devices whose functionality and aesthetics change with or against the tide. The concept of disappearance will be key as all three objects purport to replace jobs and the workers who hold such positions. These technological products all enact an erasure of work and of the working-class body, if they are understood as potential products available in a near future. As narrative devices, however, they also function as potent critical agents, underlying potential modes of resistance in our present.
Harnessing Conflict: Antagonism and Spatiotemporal Design Practices
Authors: Paez Roger , Valtchanova Manuela
Published: July 2021

This paper explores the capacities of design to interrogate the socio-spatial context in order to foreground conflict, dissent and dispute as creative practices to fuel urban transformation.
In today’s urban habitat, spaces and actions do not mesh seamlessly. The city is characterised by a disjunction between the physicality of the urban fabric as a materialisation of ideologies and the relationality of contested supremacies and entropic dynamics that inhabit it. Consequently, the practices of contemporary transformative city-making need to be reinvented through temporality and impermanence, accounting for disorder and embracing instability. In that sense, antagonism is a key element to harness in critical design practices aimed at promoting urban diversity. In this paper we study how incorporating antagonism in design practices can trigger processes of urban reformulation by constituting liminal spaces of opportunity where democratisation emerges as a spatiotemporal practice.
Two related case studies carried out in 2020 in the Raval neighbourhood of Barcelona (Subjective Cartographies: A Mirror of Diversity and Infrastructures for Public Space Interaction), are presented to explore how design can support dissidence and plurality, whether through identification and visualisation or by catalysing them as situated practices of active citizenship.
In both case studies, design fosters de-hierarchisation and trans-linearity in the city, reclaiming the right to direct action in collective urban spaces. In this sense, this paper explores how design contributes to activating multiple processes of emancipated citizenship, harnessing conflict and constructive dissent as situated spatiotemporal practices to promote diversity. Facilitating the proliferation of counter-hegemonic notions of cosmopolitics, territory, domesticity and publicness, the design practices revisited in this paper operate between politics, space and affect in order to promote intersubjective relations in public spaces, using the material, temporal and affective dimensions of design to co-create diverse and resilient urban habitats.

Processos criativos colaborativos sobre a música de Jorge Peixinho (1940-1995): explorando o idiomatismo do violão e as potencialidades da eletrônica
Authors: Baptista Pedro , Lestre Tiago , Rodrigues Pedro , Zoudilkine Evgueni
Published: July 2021

Jorge Peixinho (1940-1995) foi um compositor central no movimento musical vanguardista português da segunda metade do século XX. Da sua colaboração com o violonista Lopes e Silva (1937-2019) no seio do Grupo de Música Contemporânea de Lisboa, resultaram 21 obras com violão, compostas ao longo de 24 anos (de 1971 a 1994). Em 2020, as obras Harmónicos I e Sine Nomine de Jorge Peixinho foram transpostas para violão e eletrónica, através de processos criativos colaborativos entre violonista e compositor. Na obra LLOCK de Nuno Peixoto de Pinho, composta a partir das obras L’Oiseau-Lyre e Cantos de Sophia de Jorge Peixinho, foi possível recriar postumamente um duo imaginado com Lopes e Silva, recorrendo a uma gravação do violonista e ao software Ableton Live.

Authors: Ganc David
Published: July 2021

Este artigo é um relato de experiência da gravação audiovisual do baião Caldo de cana, composto por David Ganc em 1978 e idealizada pela Orquestra Associação Brasileira de Flautistas (ABRAF). Com o intuito de unir flautistas durante o período de distanciamento social devido à pandemia da COVID-19, a ABRAF realizou a gravação da obra de forma remota, de julho a agosto de 2020. A realização do projeto e as transformações resultantes do processo colaborativo que envolveu alguns participantes são descritas, assim como os problemas e as soluções tecnológicas encontradas na inédita tarefa de editar os áudios e vídeos produzidos pelos 220 flautistas, provenientes de todos os estados do Brasil. Os escritos de Latour (2005) e a sua teoria Ator-Rede nos auxiliam a pensar a relação humano/objeto. No nosso caso, levamos em conta a interferência facilitadora/limitadora do computador no evento gravado, e também as relações e associações que transcenderam esse coletivo de flautistas.

Modern medicine develops rapidly in the digital direction, and new information and telemedicine technologies are actively introduced in clinical practice. Purpose. To identify the category of cardiac surgical patients interested in the remote dynamic follow-up after the discharge from the hospital, using the Internet services and the factors that affect this. Material and methods. The study was conducted at the base of the department of surgical treatment of interactive pathology of the Bakoulev National Medical Research Center for Cardiovascular Surgery of the Russian Federation. The study was prospective. Before the discharge, patients answered a series of questions combined into an anonymous questionnaire. The questions concerned education, social status of the patient, age, gender, patient interest in remote follow up after discharge, use of the Internet and social networks, satisfaction with the treatment. Results. The study included 652 patients with a mean age of 58±12.5 years. 44% of them were women, 56% were men. More than 85% of patients expressed a positive opinion about such an initiative as using web services for remote consulting. Further analysis was aimed to identify possible differences between those patients who answered positively about remote follow up and those who were not interested. Statistically significant differences were revealed in the following indicators: education, sex, age, frequency of Internet use, use of social networks, place of residence and work status. Conclusions. The study confirms the demand among patients for the availability of services for their remote follow-up, which would perform the function of providing expert advice and the storage of archives of patients’ medical documents. Younger patients who are active Internet users and who have university education are potentially interested in this service. Such services would allow the patient to keep in touch with the doctor of the Department where surgical treatment was carried out, which would undoubtedly increase patients’ adherence to the treatment and recommendations.

The purpose of the study was a comparative investigation of working conditions, prevalence and structure of occupational pathology in the subjects of the Russian Arctic in 2007-2018. Material and methods. The analysis of data on socio-hygienic monitoring in the section “Working conditions and occupational morbidity” of the population in the Russian Arctic in 2007-2018 was carried out. Results. The development risks, prevalence and structure of occupational pathology in the subjects of the Russian Arctic were established to have significant differences. The most common factor causing the development of occupational pathology (32.8% of all cases) was the increased severity of labour. In three regions of the Russian Arctic, the seriousness of work was a leading risk factor: Arctic zones of the Republics of Komi and Karelia, the Murmansk region. The most unfavourable working conditions and a high level of occupational morbidity are observed in Arctic zones of the Republic of Komi (207.44 per 10,000 employees) and Krasnoyarsk Territory (20.65), the Chukotka Autonomous Okrug (12.69). The basis of the economy of these entities is formed by the mining and metallurgical industries. On the contrary, the least harmful working conditions and a low level of occupational pathology are characteristic of the gas and oil producers of the Yamalo-Nenets (1.29) and the Nenets Autonomous Okrugs (3.45). Over the analyzed period, the level of occupational morbidity in five subjects of the Russian Arctic (Arctic zones of the Krasnoyarsk Territory and the Republic of Komi, the Nenets and Chukotka Autonomous Okrugs, the Murmansk Region) tended to increase, while in other three (Arctic zones of the Arkhangelsk Region and the Republic of Yakutia, the Yamal-Nenets Autonomous Okrug) - to decrease. Conclusion. Modern targeted programs for the prevention of occupational pathology should consider the characteristics of the formation of health disorders both in general in the Russian Arctic and in its subjects.

Purpose: The purpose of this study is to examine the effects of integrated Science, Technology, Engineering, and Mathematics (STEM) education on academic achievement in the science classroom.
Methodology: This study is a quasi-experimental using non-equivalent control group pretest-posttest design. Fifty-one Grade 8 students, taught by the same teacher, constituted the participants of this study. The study consisted of an experimental group that followed a STEM approach to education and a control group that was taught the usual way.
Results: The findings showed an encouraging improvement in the science achievement of the experimental group as compared to that of the control one. Students belonging to the experimental group demonstrated conceptual understanding of the topics covered by the assigned problems.
Practical Implications: An initial implication is that STEM education is a promising approach that, if properly implemented, facilitates meaningful learning.
Originality/Value: The problem/project-based way of teaching and learning allows students to appreciate the relevance of their school work to their own lives and the world around them. Besides the positive impact of STEM education on science achievement, the findings of this study revealed that a STEM approach is a promising approach in terms of developing conceptual understanding and promoting transfer of learning.

The football coaches formation is a topic of considerable analysis and constant development. Today football coaches are very heterogeneous, whether in terms of experience as a coach, age, context of intervention and even past practice as a player. This heterogeneity may be more evident in regional football, since it is the basis of this sport, where most players and coaches begin their careers. Thus, regional football can present a big difference between the age and experience of the coaches, which leads to different views and interventions on the part of the coaches. So it is relevant to analyze the importance that coaches (expert and young) in this context give to different professional skills to understand what their convergences and divergences, 40 interviews were conducted (20 expert coaches and 20 young coaches) with an average age of 35.6 years and standard deviation of 8.6 years, following a script composed of five parts: a Personal and socio-professional characterization, the importance given by the interviewees to the Competencies: “Knowledge-Knowledge "," Knowledge-Do "and Knowledge-Be". We observed that both groups give relative importance to the different “knowledges”, however it is the Young Coaches who present the best results, with (51%) of items of (PNFT-RCFG).
