The psychobiodynamic management (PBDM) approach
Authors: Λούντζης Γεώργιος
Published: August 2023

Οι υπάρχουσες διοικητικές θεωρίες, Κλασική, Νεοκλασική και Σύγχρονη Διοίκηση, έχουν εφαρμοστεί σε επιχειρήσεις και οργανισμούς με στόχο τη βελτίωση της απόδοσης του προσωπικού όσον αφορά την παραγωγικότητα και την αποτελεσματικότητα (Kitana, 2016). Η βιβλιογραφία έχει δείξει (Petriglieri, 2020) (Mom, 2018) (Joullié & Gould, 2021) ότι, ενώ ορισμένες επιχειρήσεις έχουν ωφεληθεί από την εφαρμογή τους, άλλες όχι. Η παρούσα διδακτορική διατριβή καταδεικνύει την ανάγκη για υιοθέτηση μιας νέας διοικητικής προσέγγισης (PsychoBioDynamic Management – PBDM), η οποία, μεταξύ άλλων εννοιών, εστιάζει στον ρόλο και τους παράγοντες που επηρεάζουν την εργασιακή ικανοποίηση των εργαζομένων. Η νέα προσέγγιση αποτελείται από τις αρχές του PsychoManagement και τον τρόπο ζωής των διευθυντών. Αυτή η μελέτη σκοπεύει να διερευνήσει εάν το PBDM μπορεί να επηρεάσει στατιστικά την εργασιακή ικανοποίηση των εργαζομένων. Για τη διερεύνηση των υποθέσεων που τέθηκαν, πραγματοποιήθηκε έρευνα με ένα εκτεταμένο τυχαίο δείγμα, από ελληνικές εταιρείες/οργανισμούς διαφόρων τομέων και μεγεθών, χρησιμοποιώντας ένα κατάλληλα σχεδιασμένο ερωτηματολόγιο για την επιλογή και τη στατιστική ανάλυση σχετικών ποσοτικών και ποιοτικών πληροφοριών. Η νέα προτεινόμενη μεταβλητή προσέγγισης διαχείρισης αναμένεται να επηρεάσει εκ των προτέρων την ικανοποίηση των υφισταμένων. Τα ευρήματα και τα αποτελέσματα των στατιστικών δοκιμών επιβεβαιώνουν τη συγκεκριμένη υπόθεση και υποδεικνύουν ότι η εργασιακή ικανοποίηση των εργαζομένων επηρεάζεται –και είναι στατιστικά σημαντική– από το PBDM. Ωστόσο, υπάρχει μια σημαντική ασυμφωνία μεταξύ των αντιλήψεων των διευθυντών και των υφισταμένων τόσο για το PBDM όσο και για την ικανοποίηση από την εργασία.
Weed science research achievements on maize in Ethiopia: a review
Authors: Negewo Takele , Dechassa Nagassa , Fufa Amare , Bidira Tigist
Published: August 2023

Recent research into assessing and combatting maize weeds was reviewed based on scientific and working reports from the year 2011 onwards in Ethiopia. This review paper covered two main topics: assessment of major weed types and their impacts, and research results of weed management in the maize cropping system of the country. More than 80 major weed floras dominated by broad leaved weeds were found infesting maize fields in different localities. By competing, toxifying and/or parasitizing maize plants, they reduce the crop germination, growth and productivity. Several experiments indicated that maize yield loss due to uncontrolled weed growth varied from 35 to 87.5%, indicating that weed management is a critical factor for maize production in the country. Hoeing, hand weeding and pre-emergence herbicides application have been the most frequently used weed control practices to minimize the competition effect of weeds. So far, there has been no effective and sustainable individual weed control method for maize fields. Thus, future research should focus on developing integrated weed management that effectively reduce weed infestation and associated impacts, and improve productivity of the crop considering socio-economic condition of a specific maize producing agro-ecology of the country.

Authors: Feleshtynskyi Y. , Marshtupa O. , Antoniv V.
Published: August 2023

The aim of the work - to increase the effectiveness of surgical treatment of PVH of giant size by using the improved TAR technique.

Materials and methods. An analysis of the surgical treatment of 150 patients with post-operative abdominal hernias of giant size, who underwent posterior techniques of disconnection of the anatomical components of the abdominal wall TAR in combination with alloplasty, was performed in the period from 2016 to 2022. The main group consisted of 74 patients with post-operative ventral hernias of giant size who underwent advanced TAR technique in combination with IPOM alloplasty. The comparison group consisted of 76 patients with giant PVH who underwent the classic posterior technique of component separation TAR in combination with retromuscular alloplasty.

Results of the studies and their discussion The results of ICP measurement in patients of the main group showed that after 6-24 hours after the operation in 73 (98.6%) patients, ICP was within 7.1 ± 1.3 mmHg and only 1 (1.4%) patient had IAH of the first degree, which was caused by intestinal paresis. After conservative treatment and elimination of intestinal paresis, after 48 hours ICP was 5.7 mmHg which was normal.

In 76 patients of the comparison group who underwent classic TAR with retromuscular alloplasty, IAH of varying degrees of severity was diagnosed in 6 (7.9%) patients. Among them, 3 (3.9%) patients developed IAH of the I degree, 2 (2.6%) had IAH of the II degree and 1 (1.3%) patient had IAH of the III degree.

Authors: ERGÜRHAN İLHAN İnci , ÇAKMAKCI Selma , KAYMAK CİHAN Meriç , BAYHAN Turan , SARI Neriman
Published: August 2023

Objective: Monotherapy with a beta lactam or a cephalosporin has become the standard of care for the treatment of febrile neutropenia (FEN). We aimed to evaluate the efficacy of cefoperazone/sulbactam (CS) as empirical monotherapy for febrile neutropenia in children with solid tumors and lymphomas.

Material and Methods: Children with FEN received cefaperazone-sulbactam (80 mg/kg/day, every 8 hours). Treatment responses (a) successful, complete resolution of all signs and symptoms of infection at 72 hours and after 7 days of CS treatment; (b) success with modification, change of therapy for viral, parasitic or fungal infection or addition of glycopeptides; (c) failure was defined as the emergence of a new or resistant infection, treatment-resistant bacteremia, the need to switch to carbapenems.

Results: Our study included 157 patients and 350 febrile neutropenia episodes. The most common diagnoses were osteosarcoma (35%), Ewing sarcoma (30%), non-hodgkin lymphoma (13%) and rhabdomyosarcoma (9%), respectively. The origin of fever could not be determined in 223 (64%) of FEN episodes, 79 (22%) had microbiologically documented infection (MDI), and 48 (14%) had clinically documented infection (CDI). The success rate was 65% (229), the success rate with modification was 9% (31) and the failure rate was 26% (90). SC monotherapy was successful in 33% of attacks with MDI and in 60% of attacks with CDI. However, SC monotherapy was successful in 82% of febrile episodes of unknown origin.

Conclusion: Cefoperazone/sulbactam is effective and safe in febrile neutropenic children with solid tumors and lymphomas for monotherapy.

Changes in neurotransmitter levels, brain structural characteristics, and their correlation with PANSS scores in patients with first-episode schizophrenia
Authors: Xu Xian-Jia , Liu Tang-Long , He Liang , Pu Ben
Published: August 2023

BACKGROUND

In patients with schizophrenia, the brain structure and neurotransmitter levels change, which may be related to the occurrence and progression of this disease.

AIM

To explore the relationships between changes in neurotransmitters, brain structural characteristics, and the scores of the Positive and Negative Symptom Scale (PANSS) in patients with first-episode schizophrenia.

METHODS

The case group comprised 97 patients with schizophrenia, who were evaluated using the Canadian Neurological Scale and confirmed by laboratory tests at Ningbo Mental Hospital from January 2020 to July 2022. The control group comprised 100 healthy participants. For all participants, brain structural characteristics were explored by measuring brain dopamine (DA), glutamic acid (Glu), and gamma-aminobutyric acid (GABA) levels, with magnetic resonance imaging. The case group was divided into negative and positive symptom subgroups using PANSS scores for hierarchical analysis. Linear correlation analysis was used to analyze the correlations between neurotransmitters, brain structural characteristics, and PANSS scores.

RESULTS

Patients in the case group had higher levels of DA and lower levels of Glu and GABA, greater vertical and horizontal distances between the corpus callosum and the inferior part of the fornix and larger ventricle area than patients in the control group (P < 0.05). Patients with positive schizophrenia symptoms had significantly higher levels of DA, Glu, and GABA than those with negative symptoms (P < 0.05). In patients with positive schizophrenia symptoms, PANSS score was significantly positively correlated with DA, vertical and horizontal distances between the corpus callosum and the infrafornix, and ventricular area, and was significantly negatively correlated with Glu and GABA (P < 0.05). In patients with negative schizophrenia symptoms, PANSS score was significantly positively correlated with DA, vertical distance between the corpus callosum and the infrafornix, horizontal distance between the corpus callosum and the infrafornix, and ventricular area, and was significantly negatively correlated with Glu and GABA (P < 0.05).

CONCLUSION

In patients with first-episode schizophrenia, DA levels increased, Glu and GABA levels decreased, the thickness of the corpus callosum increased, and these variables were correlated with PANSS scores.
Treatment of refractory anti-melanoma differentiation-associated gene 5 anbibody-positive dermatomyositis complicated by rapidly progressing interstitial pulmonary disease: Two case reports
Authors: Wang Qiao-Hong , Chen Li-Heng
Published: August 2023

BACKGROUND

Anti-melanoma differentiation-associated gene 5 antibody-positive (anti-MDA5 Ab+) dermatomyositis complicated with rapidly progressive interstitial lung disease (anti-MDA5 Ab+ DM-RP-ILD) has an unclear underlying mechanism with no recommended unified treatment plan. Herein, one of the cases that we report (Case 2) was successfully treated with tocilizumab despite having lung infection.

CASE SUMMARY

Case 1 was a 30-year-old woman who was admitted due to recurrent rash for 5 mo, fever and cough for 1 mo, and chest tightness for 3 d. She was diagnosed with non-myopathic dermatomyositis (anti-MDA5 Ab+) and interstitial pneumonia, and was treated with the combination of hormone therapy and cyclophosphamide followed by oral tacrolimus. Case 2 was a 31-year-old man admitted due to systemic rash accompanied by muscle weakness of limbs for more than 1 mo, and chest tightness and dry cough for 4 d. He was diagnosed with dermatomyositis (anti-MDA5 Ab+) and acute interstitial pneumonia with Pneumocystis jirovecii and Aspergillus fumigatus infections and was treated with hormone therapy (without cyclophosphamide) and the combination of tocilizumab and tacrolimus. The condition of both patients eventually improved and they were discharged and showed clinically stable condition at the latest follow-up.

CONCLUSION

Tocilizumab could be a salvage treatment for patients with anti-MDA5 Ab+ DM-RP-ILD who are refractory to intensive immunosuppression.
Vengeance Unbound: Henning Mankell's The Man from Beijing
Authors: McKay Daniel
Published: August 2023

Abstract: The Man from Beijing depicts ethnic Chinese workers on the US transcontinental railroad, a literary development that challenges the linguistic boundaries nominally associated with Asian American Studies. Of equal importance, I argue, is the way Mankell expands the cartography of Nordic Noir to encompass capitalism's old-new frontiers in China (PRC).
"We've Got to Believe Something ": Joyce Carol Oates and Celebrity

The adulation of celebrity is one way in which an American audience reaches for something to believe in. Oates shows how the audience creates the myths and illusions that it chooses to worship.
Sir Thomas More and the Tragedy of Citizenship
Authors: Lee Tonhi
Published: August 2023

Abstract: This essay explores the historical and generic basis for a tragic reading of The Book of Sir Thomas More . The early modern period’s dominant forms of tragedy (such as revenge tragedy and historical tragedy) typically focus on the dynastic-imperial struggles of aristocratic powers against the backdrop of centralization and state-building. Sir Thomas More inverts this representational hierarchy by leaving the monarch un-represented, relegating to the background the well-known factional conflicts that undergirded the Henrician Reformation. Instead, the play dramatizes the history of Tudor consolidation from the perspective of London’s citizenry, who are made to grapple with the meaning of their own freedom in an age of mass migration. The result, I suggest, is a charter myth not of the nation-state but of London and its civic institutions: a tragic meditation on the place of the city and its citizens in the world.
Thomas Watson, Thomas Kyd, and Embedded Poetry
Authors: Vickers Brian
Published: August 2023

Abstract: In this essay, I explore the relationship between Thomas Watson and Thomas Kyd in terms of the practice of “embedded poetry,” when a poet reuses borrowings from other poets. Both Kyd and Watson deployed such borrowings skillfully and consciously for a wide range of dramatic and poetic effects. After defining and illustrating Watson’s rhetoric of “Inventions,” I argue for Watson’s authorship of The Teares of Fancie , a 1593 sonnet sequence, and explore the many textual parallels between the poetry of Teares and Kyd’s plays. A close examination of the interplay between these two poets and of Kyd’s judicious echoes of Watson’s sonnets suggests that Kyd’s rhetorical and poetical engagement with Watson’s writing inspired and enriched Kyd’s own dramatic production.
Multi-focus averaging for multiple scattering suppression in optical coherence tomography
Authors: Zhu Lida , Makita Shuichi , Tamaoki Junya , Lichtenegger Antonia , Lim Yiheng , Zhu Yiqiang , Kobayashi Makoto , Yasuno Yoshiaki
Published: August 2023

Multiple scattering is one of the main factors that limits the penetration depth of optical coherence tomography (OCT) in scattering samples. We propose a method termed multi-focus averaging (MFA) to suppress the multiple-scattering signals and improve the image contrast of OCT in deep regions. The MFA method captures multiple OCT volumes with various focal positions and averages them in complex form after correcting the varying defocus through computational refocusing. Because the multiple-scattering takes different trajectories among the different focal position configurations, this averaging suppresses the multiple-scattering signal. Meanwhile, the single-scattering takes a consistent trajectory regardless of the focal position configuration and is not suppressed. Hence, the MFA method improves the ratio between the single-scattering signal and multiple-scattering signal, resulting in an enhancement in the image contrast. A scattering phantom and a postmortem zebrafish were measured to validate the proposed method. The results showed that the contrast of intensity images of both the phantom and zebrafish were improved using the MFA method, such that they were better than the contrast provided by the standard single focus averaging method. The MFA method provides a cost-effective solution for contrast enhancement through multiple-scattering reduction in tissue imaging using OCT systems.
The minimum required overlap length for tendon transfer A biomechanical study on human tendons
Authors: Wachtel Nikolaus , Englbrecht Marc A. , Micheler Carina , Lang Jan J. , Burgkart Rainer , Giunta Riccardo E. , Wilhelm Christina J.
Published: August 2023

In tendon transfer surgeries sufficient stability of the tenorrhaphy is essential. In addition to the choice of a suitable technique, adequate overlap of donor and recipient tendons must be ensured. The aim of this study was to investigate the tensile strength with regard to tendon overlap of a recently published tenorrhaphy, termed Woven-Fridén (WF) tenorrhaphy, which displayed higher tensile strength and lower bulk when compared to the established Pulvertaft technique. For this purpose, WF tenorrhaphies with 1.5 cm, 2 cm, and 3 cm tendon overlap were performed and subsequently tested for different biomechanical properties by tensile testing. Among others, the parameters of ultimate load and stiffness were collected. Native tendons served as controls. A formula was derived to quantify the relation between tendon overlap and ultimate load. We observed that sufficient tensile strength (mean ultimate load of 217 N) is already given with a 2 cm tendon overlap. In addition, with more than 3 cm overlap length only little additional tensile strength is to be expected as the calculated ultimate load of 4 cm overlap (397 N) is approaching the plateau of the maximal ultimate load of 435 N (native tendons).
Being scene-un/seen: Demonstrations, theatricality and community afterlives in technological mediation
Authors: Wiskowski Andrew
Published: August 2023

This article examines the visibility of communities of demonstration and protest in live happening and in digital reproduction – how a protesting community becomes seen, individuals unseen and how theatrical elements are employed and deployed to enhance and augment such visibility as a scene. Looking at protests by Extinction Rebellion (XR), I observe how heightened performance/theatricality saturates their demonstrations and spawns heightened visibility. This hyper-articulates their messages as optically charged, ready for representation in photography, video and audio that can echo through media channels. Instigated with an intention for a technologically reproduced and mediatized after-event – a digital afterlife. In this sense, theatricalizing the demonstration event as performance scene makes it, and any associated messages, ready to transcend event time–space and become a demonstration hyper-object, following Timothy Morton. That is, through theatrical performance their message/statement/community becomes part of a massive entity that exists beyond local scales of space and time. As accessible, temporally extensive data such communities and messages exist far beyond the live protest. While not an object per se, XR’s messages and their affective impact contaminate and spread by being commented on, seen, retweeted, hash-tagged, forwarded, printed and so on in print and digital media spaces. In so doing, they reach far greater audiences than those at the demonstration event, amplifying their virtual spaces with the community’s application of theatricality working both as a catalyst and carrier.
Death by prox(y)imity: Participation with the pandemic through the mobile multiplayer game Among Us (2018)
Authors: Lee Andrew Martin
Published: August 2023

As in-person social interaction became widely known as the primary mode of transmission of the COVID-19 virus, alternative modes of social interaction were adopted to maintain interpersonal communication during the various lockdowns that were to come. By analysing the application of five key concepts (Goffman’s definition of the situation, Anderson’s imagined communities, Fischer-Licht’s autopoietic feedback loop, Murray’s procedural authorship and Agamben’s state of exception), we develop an assemblage for assessing Innersloth’s Among Us as a proxy for the pandemic experience.
Instagram – ‘bringing you closer to the things you love’: Ghanaian popular dance circulation through interaction within current pervasive media
Authors: Mattson Benedictus
Published: August 2023

The advent of social networking today is bringing us closer to the people, places and things we love to see. As an avenue for bridging the communication gap and advancing human interaction, social media’s pervasiveness has had tremendous impact on Ghanaian dance culture in contemporary times. Popular dancers today present their oeuvres in the form of short videos (mostly a minute) on Instagram and solicit user responses from audience of diverse backgrounds and locations. Considering this influence of globalization, its pervasive global communication media, and the move from in-person to virtual communication, it is imperative to interrogate the utilization of the social media networks (especially Instagram) by Ghanaian popular dancers in recent times as regards its impact on the proliferation of the locally created popular dances. This article is framed within the concept of Active and Affective modes of engaging with mediated dances and Connective Marginalities in addition to perspectives from globalization, social media and popular dance studies. Through the analysis of the exploits of two famous popular dancers in Ghana and specific ‘cypher pages’, I highlight the opportunities offered by Instagram as an alternative ‘cultural space’ for the marginalized youth to exhibit their creative ingenuities whilst interacting and reaching out to a wider audience within the shared mediated space.
Art and non-human agencies
Authors: Ferreira-Norman Inês
Published: August 2023

Post-human thought is permeating the art discourse, with philosophical foundations based on care for other species and a removal of human as the centre of the human universe. In this editorial, we can read about the articles published in this issue and the ways they intertwine with each other and the concepts that seep through this ethical movement. Some counterarguments will also be offered as a way to critically challenge the momentum these perspectives are taking and as a way of not losing focus on the reasons why they emerged in the first place.
Sheepology
Authors: Piddington Karen
Published: August 2023

‘Becoming-animal’, a concept devised by Gilles Deleuze and Felix Guattari, provides me with a springboard to explore new insights and perspectives outside the human experience. As an art practitioner, I enter paradoxical spaces between the wild and the domestic, to encounter non-human animals. Through shape-shifting and attuning to local ecologies, I enter these entangled worlds using both a playful and serious intent. I use a camera switched to auto and other technologies to create films and sound works from these multispecies alliances and to consider what it might be like to be non-human. These then undergo a transformative process and are given space to become something beyond my control. Ultimately, they create alternative ways of seeing and thinking about interspecies relationships. Sheepology, a film and sound work to emerge from this process, offers the viewer an opportunity to move across the human–non-human boundary, into other alien worlds and domains, to become undone and co-inhabit a multispecies environment. I plan to examine the implications of these multispecies alliances for creating a shift in awareness of the biodiversity emergency.
Circling towards intimacy: Trees, tactile reading and ecosexual non-human companionship
Authors: Coleman Rachel Elizabeth
Published: August 2023

Adopting a fresh approach to autoethnographic writing, this article unfurls tactile encounters with the more-than-human through an active exercise in readership. Situating this within ecosexual and psycho-somatic framings, the text queers kinaesthetic encounter, presenting it as holding the potential for deeper connection, understanding and amity across species. Drawing on Konik and Konik’s notion of a ‘barefoot epistemology’ (: 80), and an overlay of sensorial, critical and reflective writing, the structure of the essay enacts a mimesis of the author’s own kinaesthetic encounter, exploring the provision of research writing to offer the reader their own embodied experience. Questions of research materiality support an enlivened research encounter.
Fragment and totality
Authors: Maragaki Eleni
Published: August 2023

This article explores the notions of observation and analysis with the purpose of achieving a globalized point of view, through the lens of two different segments of work: one related to the human body and another related to the landscape. The aim is to examine the possibility of internal and external observation being the two facets of one and the same act, in order to bridge the dichotomy between fragment and totality.
Investimentos operacionais em P&D como estratégia para desempenho diferenciado
Authors: Esteves Henrique Suathê , Pessanha José Francisco Moreira , Cardoso Ricardo Lopes , Viana Renata Kaori Tani
Published: August 2023

Objetivo: Analisar se as estratégias de investimento operacional com foco em P&D contribuem para a geração de retornos diferenciados em comparação a estratégias com foco em Capex.

Métodos: Com base nos modelos de precificação de 3, 5 e 6 fatores de Fama e French, a geração de retornos diferenciados foi aferida pelos retornos anormais de portfólios criados para segregar as ações por tamanho e por níveis de P&D ou Capex.

Resultados: Não foi observada relação significativa entre níveis de Capex e aumento nos retornos anormais. Nos portfólios organizados por P&D foi observada uma relação significativa entre níveis de P&D e aumento nos retornos anormais para as microações e ações de empresas pequenas, independentemente do modelo utilizado. Foi verificado também que a geração de retornos anormais por parte das microações que investem agressivamente em P&D independe do seu nível de investimentos em Capex.

Contribuição: Confirma à literatura que a relação entre retornos anormais e investimentos operacionais em P&D advém, principalmente, das ações com baixo valor de mercado, mesmo com a utilização de retornos ponderados, sendo robusta aos principais modelos de precificação da atualidade.
Framing Chinese Treatment of Africans in Guangzhou
Authors:   Lagos State University, Oshodi Abdul-Gafar
Published: August 2023

The treatment of Africans in Guangzhou, China in 2020 during the COVID-19 pandemic – here referred to as the ‘Guangzhou episode’ – generated strong criticisms and made news headlines within and outside Africa. This paper analyses the reportage of the episode in four online African newspapers: two each from Nigeria and Ghana. Specifically, it sheds light on how the episode was framed, comparing coverage between both countries. Using a discourse analysis that prioritizes language, source, and focus, the paper demonstrates that while western media were important influence/source for the newspapers, the African migrants’ experiences in the episode was largely framed within (ahistorical) victimhood. Yet, the idea of ‘African’ migrants had a noticeable Nigerian dimension.

Published: August 2023

O Professor Murilo Fernando Neuppmann Feres nasceu em Araxá/MG e obteve seu diploma na Faculdade de Odontologia de Ribeirão Preto na Universidade de São Paulo em 2002. Quatro anos após sua graduação, se especializou e se tornou Mestre em Ortodontia pela Pontifícia Universidade Católica de Minas Gerais. Concluiu sua formação na Universidade Federal de São Paulo, onde obteve o grau de Doutor em Medicina, avaliando desfechos em Otorrinolaringologia úteis para a prática ortodôntica. O meu primeiro contato com o Prof. Murilo aconteceu em Belo Horizonte durante o Congresso da Associação Brasileira de Ortodontia, em 2011. Tínhamos um amigo em comum e desfrutamos do maior evento da Ortodontia brasileira por quatro dias. Naquela época, o Dr. Murilo mantinha sua prática em um consultório particular e era professor na Universidade de São Francisco, em Bragança Paulista. Nos encontramos novamente, inesperadamente, em Edmonton/Canadá, em 2014. Já com vínculo na Universidade de Guarulhos, o Prof. Murilo era um estagiário de pós-doutorado com bolsa da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) no Departamento de Odontologia da Universidade de Alberta, onde eu realizava um programa de Doutorado Sanduíche com bolsa da mesma agência de fomento. Naquele ano, tivemos a oportunidade de trabalhar com Prática Baseada em Evidências, sob a tutela do Prof. Carlos Flores-Mir. Após trabalho árduo e participação de outros pesquisadores brasileiros, o Dr. Murilo foi primeiro autor na publicação de duas revisões sistemáticas abordando a interceptação da mordida aberta anterior, em um dos periódicos mais prestigiosos da Ortodontia, o European Journal of Orthodontics. Com a sua volta ao Brasil, tem devotado seu tempo ao estudo aprofundado desse tema. Desde 2018, é professor no Departamento de Clínica Infantil da Faculdade de Odontologia de Ribeirão Preto, onde ministra aulas e conduz pesquisas em Ortodontia e Odontologia Baseada em Evidências. Além de um grande amigo, o Prof. Murilo é uma inspiração, pelo seu amor à profissão e seriedade em tudo que se propõe a fazer.
Mantenedor de espaço distal shoe modificado: não invasivo e funcional
Authors: Caldas Luciana Duarte , Gutierrez Gabriela Mancia de , Sant'Anna Eduardo Franzotti
Published: August 2023

INTRODUÇÃO: A manutenção do espaço após a perda precoce de segundos molares decíduos é imperativa para evitar a mesialização do primeiro molar permanente, especialmente se esse ainda não irrompeu. Entre os tipos de mantenedores de espaço descritos na literatura, encontram- se o distal shoe e suas variações. Entretanto, devido à necessidade desse aparelho ser inserido subgengivalmente para se conseguir contato direto com o osso alveolar, ele pode se tornar a porta de entrada para agentes infecciosos, sendo, então, um aparelho ortodôntico raramente usado na prática clínica. Além disso, esse mantenedor não é funcional, uma vez que não evita a extrusão do dente antagonista ao dente extraído. OBJETIVO: Demonstrar a fabricação de um mantenedor de espaço do tipo distal shoe, simultaneamente, não invasivo e funcional. Assim é possível evitar as desvantagens inerentes ao modelo tradicional e a qualquer uma de suas outras variantes.

Authors: Sabouni Waddah , Srirengalakshmi Muthuswamy Pandian , Adel Samar M. , Vaid Nikhilesh R.
Published: August 2023

INTRODUÇÃO: O tratamento com alinhadores transparentes provou ser eficiente na correção da mordida aberta anterior, que pode ser promovida pela intrusão dos dentes posteriores ou extrusão dos anteriores. Considera- se que os alinhadores transparentes são eficientes na intrusão dos dentes posteriores, mas ineficientes na extrusão dos anteriores, e muitas vezes requerem o uso de acessórios como elásticos intrabucais. OBJETIVO: O presente relato de caso demonstra um protocolo de estagiamento eficiente e planejamento da geometria dos attachments com o sistema Invisalign para realizar a extrusão anterior sem o uso de elásticos.
Reabsorções dentárias não têm causas sistêmicas
Authors: Consolaro Alberto
Published: August 2023

OBJETIVO: Fundamentar que as reabsorções radiculares não têm causas sistêmicas, revisando os conceitos históricos e duas teses de doutorado sobre o assunto. METODOLOGIA: Será apresentada uma síntese sobre as duas teses, para que possam ser assimiladas pelos clínicos ortodontistas. DISCUSSÃO: Antigamente, os resultados e conceitos eram relacionados com a tentativa de usar as causas sistêmicas como uma forma de justificar as iatrogenias, que geralmente estavam associadas às limitações tecnológicas que existiam. CONCLUSÃO: Frente a casos de reabsorções radiculares na prática ortodôntica, deve-se: 1) Resgatar os fatores preditivos locais, que podem ser identificados no planejamento ortodôntico; 2) Reanalisar minuciosamente os fatores locais relacionados com a morfologia dentária e óssea, que devem ser considerados como fatores preditivos de reabsorções radiculares durante a movimentação osteodentária induzida ortodonticamente; 3) Rever os princípios relacionados com a mecânica aplicada no caso em que as reabsorções radiculares foram diagnosticadas; 4) Considerar que não existem fatores ou causas sistêmicas relacionadas com as reabsorções dentárias, associadas ou não com a prática ortodôntica.

OBJETIVO: Relatar o caso clínico de um paciente adulto com má oclusão Padrão III. DESCRIÇÃO: O paciente apresentava maxila deficiente, mandíbula bem posicionada, lábio inferior à frente do lábio superior, Classe II de molares direita e Classe III de caninos direita, ¼ de Classe III esquerda (relação pré-molar) e mordida cruzada anterior. Os dentes #14, #15, #25 e #26 estavam ausentes e o dente #16, cruzado com o #46. Apresentava, ainda, perda óssea na região dos dentes #25 e #26, leve extrusão do #36, devido à ausência do antagonista, desgastes nas faces incisais dos dentes #11 e #21, e incisivos inferiores vestibularizados. O tratamento consistiu no uso de barra palatina para corrigir o giro dos molares superiores e expandir o dente #16, seguido do fechamento de espaços entre o #24 e o #27, juntamente com controle de ancoragem com elásticos intermaxilares de Classe III. Na sequência, foram feitos suaves desgastes interproximais dos incisivos inferiores, para eliminar espaços negros e criar espaço para a lingualização dos incisivos inferiores. RESULTADOS: Melhora na relação dos lábios superior e inferior, ficando ambos com o mesmo comprimento, e correção da mordida cruzada anterior, descruzamento dos dentes #16 e #46, espaços adequados para implantes na região dos dentes #14 e #24, correção do ângulo interincisal e das guias de caninos e incisivos.

INTRODUÇÃO: O uso de mecânicas auxiliares no tratamento com alinhadores ortodônticos é uma realidade nessa modalidade de tratamento. A customização realizada pelo ortodontista pode ser uma dificuldade enfrentada durante a prática clínica. OBJETIVO: Demonstrar a confecção de um recorte retentivo em alinhadores ortodônticos para uso de elásticos intermaxilares. MÉTODO: A confecção é realizada com o auxílio de discos diamantados e brocas esféricas, instrumentos de uso rotineiro dos ortodontistas. RESULTADOS: O recorte permite maior retenção do elástico no alinhador, além de facilitar a correta inserção pelo paciente. CONCLUSÃO: O recorte para elásticos intermaxilares em alinhadores ortodônticos, quando realizado por ortodontistas, pode diminuir as intercorrências clínicas durante o tratamento ortodôntico.
Os dez destinos de um dente não irrompido

OBJETIVO: Fundamentar o profissional para as indicações de exodontia de dentes não irrompidos, pois esses podem permanecer muito tempo sem induzir qualquer alteração ou consequência, mas são imprevisíveis no tempo, no tipo de acontecimento e nas complicações. METODOLOGIA: A partir da experiência clínica e laboratorial, desenvolveram- se raciocínios lógicos e biológicos sobre os possíveis destinos que um dente não irrompido pode ter quando persistir no interior dos maxilares. DISCUSSÃO: Algumas consequências não requerem tratamento, apenas compreensão clínica e acompanhamento imagiológico. Outras, porém, requerem tratamento assim que diagnosticadas. Quando não removidos, os dentes não irrompidos devem ser controlados imagiologicamente, preferencialmente por meio de tomografias anuais, pela imprevisibilidade de suas evoluções. Algumas, quando surgem, devem-se ser tratadas imediatamente. Essas possibilidades devem ser discutidas para cada dente especificamente, abordando- se tópico a tópico. Postergar a remoção cirúrgica de dentes não irrompidos, mesmo que com controles anuais, também implica em postergar o momento de um possível problema, que pode ser ampliado no espaço e no tempo!

O Tico-tico e seus Fubás: a economia cultural do choro no cinema
Authors: W. Schulze Peter
Published: August 2023

Considerado um dos gêneros musicais brasileiros por excelência e tido no discurso como expressão genuína da brasilidade, o choro se internacionalizou através da indústria cultural estadunidense, especialmente em adaptações cinematográficas hollywoodianas na década de 1940, inseridas numa circulação transmidiática que incluía sinergias com produções de discos e transmissões radiofônicas. Um choro em particular circulou de tal maneira na “economia cultural multicêntrica” (Curtin 2008) globalizada que virou uma das canções brasileiras mais conhecidas internacionalmente: Tico-tico no Fubá, composta por Zequinha de Abreu, em 1917. Ao analisar as adaptações desta canção, este artigo contribui não só para a elucidação da história do choro e sua globalização cinematográfica, mas também para questões relacionadas com as estruturas transmidiáticas de gêneros e suas funções na indústria cultural transnacional, que incluem o papel das estrelas na “comodificação global da diferença cultural” (Huggan 2001).
Abraços possíveis: interdições e resistências na exibição cinematográfica de imagens periféricas
Authors: Souza Scheilla Franca de , Bogado Angelita , Cardoso Filho Jorge
Published: August 2023

Refletimos, neste artigo, sobre experiências de circulação de imagens durante a pandemia a partir de audiovisuais dedicados aos abraços interrompidos, provocados tanto pela COVID-19 como pelos apagamentos históricos coloniais, inclusive no setor de exibição cinematográfico. Onde e como os “abraços possíveis” foram construídos com o espectador, uma vez que as moradas tradicionais do cinema estavam totalmente interditadas? Inspirados no movimento do Samba de Roda do Recôncavo Baiano, manifestação artística do século XVII, propomos uma “montagem umbigada” como metodologia de encontro entre imagens, que revelam potências e crises da exibição cinematográfica e sua relação com o audiovisual numa rede que liga obras entre si e as obras e nós, espectadores. Fortalecidos nos ecos do comum, os “corpos-tela” transcendem interrupções e binarismos, mesmo sob silenciamentos do colonial, para além do pandêmico.
¿Qué crisis y para quién? el rol del Cine Arte Normandie y la exhibición de cine en Chile (1982-2001)
Authors: Peirano María Paz , Bossay Claudia , Pinto Veas Iván
Published: August 2023

Este artículo se refiere al rol de los cines de arte y ensayo en contextos de crisis de exhibición. Se focaliza, en particular, en la gestión del Cine Arte Normandie entre 1982 y 2001 frente a dos grandes crisis de la exhibición cinematográfica en Chile – la década de 1980, durante la dictadura militar, y la década de 1990, luego del retorno a la democracia – que se relacionaron tanto con el contexto local como con las dinámicas de la industria cinematográfica global. El artículo analiza la particular posición del Normandie dentro del medio chileno, revelando los modos en que un tipo particular de cine (cine arte o cine de calidad) se exhibió, a pesar, y en respuesta, a dichas crisis. El caso del Normandie, una sala que sobrevivió a las cambiantes condiciones de la exhibición cinematográfica, revela no solo las particularidades de los modos de exhibición y las distintas implicancias de dichas crisis para la cultura cinematográfica local, sino también cómo las diferentes crisis de exhibición abren la perspectiva sobre las condiciones de exhibición del cine global.

The study investigated the thermal performance of a photovoltaic thermal (PVT) collector with a twisted absorber tube and nanoparticle-enhanced phase change material (nano-PCM). The PVT collector consisted of twisted absorber tubes, a container filled with nano-PCM, and a photovoltaic (PV) panel. To assess its efficiency, five different configurations were tested using an indoor solar simulator. The configurations analyzed were as follows: (a) an unenhanced PV panel, (b) PVT with circular absorber tubes (C-PVT), (c) PVT with twisted absorber tubes (T-PVT), (d) C-PVT with nano-PCM (C-PVT-PCM), and (e) T-PVT with nano-PCM (T-PVT-PCM). The thermal, photovoltaic, and combined photovoltaic-thermal efficiencies were evaluated at varying mass flow rates (0.008-0.04kg/s) and a constant solar irradiance of 800W/m2. Among the configurations tested, the T-PVT-PCM configuration demonstrated the highest performance. Specifically, at a mass flow rate of 0.04kg/s, solar irradiance of 800W/m2, and an ambient temperature of 27°C, it achieved photovoltaic, thermal, and combined photovoltaic-thermal efficiencies of 9.46%, 79.40%, and 88.86%, respectively. The utilization of twisted absorber tubes in the design notably improved thermal efficiency by enhancing heat transmission between the liquid and the tube surface. Furthermore, the implementation of T-PVT-PCM led to a significant reduction in surface temperature. Compared to the unenhanced PV panel, it lowered the surface temperature by approximately 30°C, and when compared to C-PVT-PCM, it reduced it by around 10°C. Notably, T-PVT-PCM outperformed the unenhanced PV panel by exhibiting a 34.5% higher photovoltaic efficiency. Overall, the study highlights the performance of the PVT collector with twisted absorber tubes and nanoparticle-enhanced phase change material. The innovative design achieved remarkable thermal efficiency, reduced surface temperatures, and significantly enhanced photovoltaic efficiency compared to traditional configurations. These findings contribute to the development of more efficient and versatile solar energy systems with the potential for broader applications in renewable energy technology.

Published: August 2023

Objectives

Studies already pointed out the increased risk of human papillomavirus (HPV) positivity and the implied risk of cervical dysplasia and even cervical carcinoma in pregnant women with human immunodeficiency virus (HIV) infection. Nevertheless, due to less data there is still no standardised and expanded screening for this high-risk group.

Content

Two online databases (PubMed, EMBASE) were used to identify eligible studies. Results are shown in percentages. Wherever useful the arithmetic mean was calculated.

Seven studies were included. Pregnant WLWH showed HPV prevalence between 34 and 98.4 %. Different sensitivity and specificity among PCR methods for HPV detection could be a reason for the large range concerning HPV prevalence. Risk factors like Age, Smoking, Sexuality, HIV status and education level should always be taken into account. Association between HPV prevalence and level of CD4 cells or HIV virus load was seen. In which way use of Antiretroviral Therapy (ART) could decries the risk for HPV infections is still discussed. When cytology was performed only few high-grade squamous intraepithelial lesion (HSIL) were found.

Outlook

Standardisation and expansion of preventive screening for cervical dysplasia and carcinoma for pregnant WLWH is necessary. Then better comparability of the data will also be achieved.
The application of iterative hard threshold algorithm based on nonlinear optimal compression sensing and electronic information technology in the field of automatic control
Authors: Jiang Kun , Bradha M.
Published: August 2023

To improve the accuracy effect of the iterative hard threshold, an improved iterative hard threshold (IHT) method is proposed. The specific contents of this method include the principle of an IHT algorithm based on compression sensing (nonlinear optimization), weighted least squares improvement, the establishment of an IHT algorithm model based on weighted least squares improvement, and the experimental research of traditional algorithms and improved algorithms on one-dimensional signal reconstruction. The results show that the improved IRLSIHT algorithm takes 8.37, 29.63, and 30.86 s when the sampling rate is 0.2, 0.5, and 0.8, respectively, and the signal-to-noise ratio is 20.11, 27.47, and 31.82 dB, respectively. Compared with the traditional IHT algorithm, it takes a long time, which is a deficiency, but the signal-to-noise ratio is the largest, and the improved algorithm improves the accuracy. It has been proven that combining the method proposed in this article with automatic control can significantly save time and increase industrial output.
War, Language and Culture
Authors: Pchelintseva Olena
Published: August 2023

The article presents the analysis of the changes, which have occurred in the linguistic and cultural public consciousness of the Ukrainians since the Russian invasion into Ukraine on February 24, 2022. The research was conducted based on the results of online survey involving respondents from the educational and cultural spheres (teachers, lecturers, museum and library workers, theatrical and literary workers). The choice of this target group was based on the assumption that this professional group is the most sensitive to any changes in the sphere we aim to study. People employed in culture and education are capable of self-reflection, and, in accordance with their professional functions, they have an obvious intellectual, moral, and ethical influence on society, thus bearing the responsibility for the situation and broadcasting their position and attitude to the linguistic situation and culture. According to the results of the survey, many bilingual informants refuse to use Russian, and Russian-speaking Ukrainians attempt to start speaking Ukrainian by studying it independently or taking courses. The analysis showed that Cancelled Russian culture is a phenomenon relevant not only for virtual space. Negative attitudes towards Russia are transferred to classical Russian literature, to Russian-language music content, and, to a lesser extent, to modern fiction. At the same time, a third of the respondents directly or indirectly approve of the use of taboo (swear) words and expressions in public space. The study makes it possible to understand the dynamics of public attitude and the general vector of linguistic and cultural changes.
