Morphological Characteristics of Bone Callus During Acceleration of Bone Healing in TBI-related Polytrauma
Authors: Bihun Roman , Yurakh Omelian
Published: February 2025

Background. The phenomenon of accelerated fracture healing in patients with cranio-skeletal polytrauma was first described qualitatively in 2005 by Morley. Already existing morphological studies allowed to form a clear hypothesis about the mechanism of formation of heterotopic ossifications after traumatic brain and spinal cord injuries. Morphological analysis of fracture healing is one of the leading methods for identifying the underlying mechanism.
Materials and methods. Adult white rats (n=90) were divided into two same size groups: TBI-related polytrauma group and sham group. Harvesting was performed on day 7, 14, and 21. In both groups closed femur fracture was modelled. Modeling of polytrauma in animals of group 1 was achieved by modelling closed TBI followed by fracture of the femur, contralateral to the side of the brain lesion, by method described above. Animals were euthanized on days 7, 14, and 21 after surgery collecting of bone callus in the fracture area and the brain tissue which were examined by both light and electron microscopy.
Results. The study of histological sections of the callus in animals with an isolated fracture on the seventh day showed its connective tissue organization. Ultrastructural analysis reveals activated fibroblasts with well-developed membrane organelles in the cytoplasm. Examination of section series from polytrauma group on day 7 demonstrates the presence of skeletal tissue components, such as cartilage and bone, in addition to connective tissue elements. The light-microscopy of the connective tissue components of the callus reveals its vascularization and grouping of collagen fibers into bundles. In animals with polytrauma on the day 14, the callus has cartilaginous and bone structures, while cytoplasm is characterized by pronounced granularity. On the day 21, the callus of animals with an isolated fracture contains islands of cartilage tissue, which is represented by a few isogenic groups of chondrocytes surrounded by a connective tissue framework. The callus of animals with polytrauma on day 21 has elements of calcified bone matrix, which makes it difficult to make sections. Further examination reveals numerous trabeculae with osteocytes in the unligated bone matrix with islands of multinucleated osteoclasts.
Conclusions. In animals with polytrauma, the dynamics of transformation is accelerated in time, when cartilage tissue elements and activated osteoblasts are observed on the seventh day, and loci of calcified bone matrix are already detected on the twenty-first day. This dynamics confirms the existing theory of acceleration of fusion in the cranial component of the injury. Further studies of the intermediate bone repair terms are needed.
Some Aspects of Modern Diagnosis and Surgical Tactics in Follicular Thyroid Neoplasms
Authors: Pasko Andrii , Skrypko Vasyl
Published: February 2025

The study analyzed the examination and treatment outcomes of patients with surgical thyroid pathology.
Objective: to systematize preoperative diagnostic methods and develop a comprehensive approach to organ-preserving surgeries in patients with follicular thyroid neoplasms.
Material and Methods. The study analyzed the examination and treatment outcomes of 749 patients treated at the Precarpathian Clinical Oncology Center, Ivano-Frankivsk, Ukraine, between 2019 and 2024. All patients underwent fine-needle aspiration biopsy of clinically significant thyroid gland nodules at the preoperative stage.
Results. The causes of the disease were as follows: colloid nodular goiter in 566 (75.6%, 95% CI 72.3-78.6%) patients, adenomatous nodular goiter with follicular neoplasms in 72 (9.6%, 95% CI 7.612.0%) cases, papillary carcinoma in 54 (7.2%, 95% CI 5.5-9.3%) patients, suspicious for papillary carcinoma in 17 (2.3%, 95% CI 1.3-3.6%) cases (based on cytological examination), medullary carcinoma in 12 (1.6%, 95% CI 0.8-2.8%) patients, anaplastic carcinoma in 6 (0.8%, 95% CI 0.3-1.7%) cases, and other tumors in 22 (2.9%, 95% CI 1.8-4.4%) patients. The results were statistically processed using the standard software package “Statistica 6.0 for Windows” (StatSoft, USA).
Hemithyroidectomy was performed in 28 (42.4%, 95% CI 0.31-0.54%) cases, thyroidectomy in 16 (24.2%, 95% CI 0.12-0.32%) cases, subtotal lobectomy in 19 (28.7%, 95% CI 0.16-0.37%) cases, and lobectomy in 9 (13.6%, 95% CI 0.05-0.20%) cases. Central compartment lymph node dissection as an adjunct to thyroidectomy was performed on six (31.0%, 95% CI 0.32-0.61%) patients.
Conclusions.

The primary method for preoperative diagnosis of follicular neoplasms is fine-needle aspiration biopsy, followed by cytological examination.
In follicular neoplasms against the background of multinodular goiter, thyroidectomy is recommended. In all other cases, the initial surgical approach should prioritize organ-preserving procedures to improve quality of life.
The extent of the final surgical intervention depends on the pathological findings.
If a patient with follicular neoplasms refuses surgery, prolonged monitoring by an oncological surgeon is essential.

Molecular genetic diagnostics can facilitate the preoperative identification of follicular carcinoma, guiding the subsequent treatment algorithm.

Evaluation of the Quality of Delirium Website Content for Patient and Family Education: Cross-Sectional Study (Preprint)
Authors: Krewulak Karla , Strayer Kathryn , Jaworska Natalia , Spence Krista , Foster Nadine , Kupsch Scotty , Sauro Khara , Fiest Kirsten M
Published: February 2025

BACKGROUND

Patients and families who have experienced delirium may seek information about delirium online, but the quality and reliability of online delirium-related websites are unknown.

OBJECTIVE

This study aimed to identify and evaluate online delirium-related websites that could be used for patient and family education.

METHODS

We searched Microsoft Bing, Google, and Yahoo using the keywords “delirium” and the misspelled “delerium” to identify delirium-related websites created to inform patients, families, and members of the public about delirium. The quality of identified delirium-related website content was evaluated by 2 authors using the validated DISCERN tool and the JAMA (Journal of the American Medical Association) benchmark criteria. Readability was assessed with the Simple Measure of Gobbledygook, the Flesch Reading Ease score, and the Flesch Kincaid grade level. Each piece of website content was assessed for its delirium-related information using a checklist of items co-designed by a working group, which included patients, families, researchers, and clinicians.

RESULTS

We identified 106 websites targeted toward patients and families, with most hospital-affiliated (21/106, 20%) from commercial websites (20/106, 19%), government-affiliated organizations (19/106, 18%), or from a foundation or advocacy group (16/106, 15%). The median time since the last content update was 3 (IQR 2-5) years. Most websites’ content (101/106, 95%) was written at a reading level higher than the recommended grade 6 level. The median DISCERN total score was 42 (IQR 33-50), with scores ranging from 20 (very poor quality) to 78 (excellent quality). The median delirium-related content score was 8 (IQR 6-9), with scores ranging from 1 to 12. Many websites lacked information on the short- and long-term outcomes of delirium as well as how common it is. The median JAMA benchmark score was 1 (IQR 1-3), indicating the quality of the websites’ content had poor transparency.

CONCLUSIONS

We identified high-quality websites that could be used to educate patients, families, or the public about delirium. While most delirium-related website content generally meets quality standards based on DISCERN and JAMA benchmark criteria, high scores do not always ensure patient and family-friendliness. Many of the top-rated delirium content were text-heavy and complex in layout, which could be overwhelming for users seeking clear, concise information. Future efforts should prioritize the development of websites with patients and families, considering usability, accessibility, and cultural relevance to ensure they are truly effective for delirium education.
Discourse of Khakot Lampung Dance as A Political Technology of The Body to Make Individuals Obedient
Authors: Jamil Sulhan , Kasiyan Kasiyan
Published: February 2025

This article examines the role of traditional Khakot dance in Lampung as a discourse of political technology that influences the body to make individuals obedient to the values and social cultural norms of Lampung. This research focused on three issues. First, the form of representation of the body that complies with the social values and norms of Lampung culture in Khakot dance. Second, the process of forming a body that abides by the social values and norms of Lampung culture in Khakot dance. Third, identifying factors that influence individual compliance with sociocultural values and norms in the context of Khakot dance. This study used a critical discourse analysis paradigm and utilized primary and secondary data. Analysis of all obtained data was carried out textually and contextually using Michel Foucault's body discipline theory which is presented in a qualitative descriptive form. The results showed that the representation of the body that obeys the social values and norms of Lampung culture is reflected in aspects of Khakot dance performances, including the selection of costume forms and choreographic forms such as movement and floor pattern composition. The process of forming the body to be obedient to the social values and norms of Lampung culture in the context of Khakot dance involves formal and non-formal education, as well as through sociocultural activities in Lampung society. Factors that influence individual compliance are social control, normalization, and panopticon.
Festival and Urban Identity: A Case Study of the Malang Flower Carnival in Yogyakarta
Authors: Kumoro Nindyo Budi , Apriwan Franciscus , Maghfiroh Lailatul , Albahri Abdul Charis
Published: February 2025

Cultural festivals, often called carnivals, events, or celebrations, have become prominent showcases across Indonesia, particularly in the post-New Order period. These festivals serve two main objectives: promoting tourism and reviving regionalism as well as traditional identities in response to past centralization policies. This study examines the Malang Flower Carnival (MFC) in Malang City, East Java, which has been a key feature of the city's cultural landscape since 2010. In 2022, the MFC deviated from its tradition by participating in the Jogja Fashion Carnival in Yogyakarta instead of holding its own event in Malang. This shift provides a unique opportunity to analyze how Malang's cultural identity is represented to an audience in another city. The findings suggest that while the MFC captivated visitors with its elaborate costumes, it struggled to convey the intended narrative of Malang's cultural identity. This difficulty stems from the complexity of representing Malang's multiple identities—rooted in its historical legacy, contemporary identity as the "City of Flowers," and broader regional narratives. The themes of bravery and heroism, although recognized, were often disconnected from Malang's broader historical and cultural context

Authors: Kartika Ema , Wicaksono Harto
Published: February 2025

The tradition of jamasan pusaka (heirloom washing), or simply jamasan,  in Batang District involves various types of plants initsrituals. Plants, as part of the local cultural heritage, play an important role in maintaining the balance of parallelism and interrelationship between macrocosm and microcosm. Over time, this tradition has evolved, and this article aims to explorethe relationship and changes in ethnobotanical knowledge within the jamasan practice. It also analyzeshow the immanent and the transcendental functions of plantsare interpreted. Using a qualitative research method with an ethnographic approach, data were collected through observation, interview, and visual documentation. The study identified 19 types of plants involved in the jamasan tradition. These plants , based on local knowledge, hold immanent and transcendental functions that are important for the continuity of the practice. The plants are categorized into mandatory elementsbased on immanent meaning, symbolic meaning, and non-mandatory elements. Jamasan is not merely the washing of heirlooms, butalso serves as a life guide for living meaningfully. Over time,the tradition has undergone transformations, with shifts from sacred to profane functions and from immanent to transcendental meanings. These changes have reconstructed the practice of jamasan in the present day.

The social participation of people with rheumatoid arthritis is assessed using the Social Role Participation Questionnaire. The aim of this study was to translate the Social Role Participation Questionnaire into the Serbian language, and to investigate its reliability and validity for Serbian people with rheumatoid arthritis. Questionnaires were satisfactorily completed by 126 participants with rheumatoid arthritis, during 2021. Test-retest reliability, internal consistency reliability, and construct validity of the Serbian version of the Social Role Participation Questionnaire were evaluated using the intraclass correlation coefficient, Cronbach’s alpha, and Spearman’s correlation coefficient, respectively. Some single item scores showed floor and/or ceiling effects. This was particularly evident in the physical difficulty items, which showed a floor effect in 20-80% of participants. The high intraclass correlation coefficient score (0.913–0.959) suggested a very high test-retest reliability. The Cronbach’s alpha coefficient, ranging from 0.706 to 0.926, was reliable for the majority of internal consistency. With the exception of the Social Role Participation Questionnaire subscale role importance at the first measurement, the construct validity of this instrument was confirmed. In assessing the social participation of Serbian people with rheumatoid arthritis, the Serbian translation of the Social Role Participation Questionnaire is a trustworthy and valid instrument.

Authors: Kostić Vladimir , Kostić Aleksandar , Milićević Srđan
Published: February 2025

Building a green economy is a complex process whose dynamics, among other things, are directly related to the application of many traditional and new concepts within the framework of natural capital management. In this paper, the essence of numerous concepts widely applied in the management of natural capital and the construction of a green economy, as well as the achievement of sustainable development goals, is explained by means of descriptive analysis. Using panel regression analysis, a model was created to determine the impact of changes in the use of natural resources, the state of the environment and gross national income on the sustainable development index of 166 countries in the period between 1990 and 2019. Research has confirmed the finding that the growth of the material footprint, gross national income per inhabitant, and CO2 emissions per inhabitant have a negative impact on the index of sustainable development. The obtained results speak of the necessity of building a green economy in order to stop the further growth of the ecological footprint and reduce CO2 emissions per inhabitant. The results also implicitly point to the imperative of increasing efficiency and improving the effectiveness of natural capital management in order to build a green economy and achieve the goals of sustainable development.

Ensino de argumentação para emancipação e decolonialidade
Authors: Piris Eduardo Lopes
Published: February 2025

Nos últimos anos, temos visto esforços acadêmicos no sentido de conceber a argumentação como uma prática social de discussão de questões controversas balizada não por axiomas, universalismos e atemporalidades, mas pelas condições sócio-históricas e culturais de um grupo, que nem sempre visam ao consenso, mas ao aprofundamento das diferenças. Nesse contexto, nossas pesquisas e as de grupos parceiros articulam os estudos da argumentação com os do letramento, elaborando propostas de ensino menos tecnicistas e mais voltadas ao desenvolvimento da criticidade, reflexividade e da dialogicidade, para promover a inserção dos estudantes em práticas sociais de linguagem que os desafiam a mobilizar suas capacidades argumentativas. Neste ensaio, adicionamos os propósitos do pensamento decolonial à proposta de ensino de argumentação em perspectiva emancipadora. Assim, (1) salientamos a preponderância da dimensão cultural nas interações argumentativas para a elaboração dos planejamentos de ensino, que visem à decolonialidade do ser; (2) destacamos a importância de ensinar o estudante a colocar um assunto em questão como forma de promover a curiosidade epistemológica e, portanto, a criticidade perante as razões dos acontecimentos e as ações a tomar, como estratégia para focalizar a decolonialidade do saber. Por fim, por considerar que a argumentação não é uma atividade alexitímica, discutimos a problemática das paixões na argumentação

Published: February 2025

Coffee leaf rust is a major threat to global coffee production, causing significant yield and quality losses. Traditional detection methods rely on manual inspection, which is labor-intensive, time-consuming, and susceptible to human error. This study presents an automated system for detecting coffee leaf rust using image processing techniques, combining Otsu's thresholding method with mathematical morphology to accurately identify rust-affected areas in digital images. The methodology addresses challenges such as variability in image quality, noise, and segmentation accuracy. Using a dataset of manually annotated images, the system's performance was evaluated with the Dice coefficient, demonstrating its effectiveness. Finally, we compare the results with a method that uses genetic algorithms to achieve the same goal, obtaining good results despite using a much simpler process.

Authors: Ferreira Luísa , Melo da Silva Michel
Published: February 2025

Due to the increasing requirement for police officers to wear body cameras, there is an increased need for algorithms that can automatically detect relevant moments in footage. This paper presents an automated system that uses audio and video inputs to highlight key events in recordings, reducing the need for operators to watch entire videos. Our method detects firearms and crowd gatherings with object detection, identifies people raising their hands with pose estimation. We also detect sound patterns such as sirens, gunshots, and shouts and use Automatic Speech Recognition to transcribe conversations and identify keywords for relevant events. Our system, evaluated with videos from YouTube channels such as PMTVSP, PoliceActivity, and Code Blue Cam, effectively identifies significant moments in security footage where agents are engaged in activities beyond routine patrol, thus avoiding the need for a human to watch the entire video to point out relevant moments.

Authors: De Oliveira Costa Pedro Lucas , De Oliveira Costa Thiago Matheus , Ferreira Rodrigues Moreira Larissa , Furtado Pinto Silva Leandro Henrique , Mari João Fernando
Published: February 2025

In the agricultural sector, pest detection is vital, and given the susceptibility of human analysis to errors, deep learning solutions such as Convolutional Neural Networks (CNNs) provide a promising alternative. Classifying insect pests is challenging due to the high variability among species across different regions and their various life stages. In this study, we evaluate several deep learning models and training strategies for automatic pest image classification. We analyze four CNN architectures—AlexNet, ResNet-50, EfficientNet, and Vision Transformer (ViT). Following a hyperparameter optimization step, the models were fine-tuned, and we examined the impact of four data augmentation strategies on classification performance using the Agricultural Pests dataset. ViT demonstrated superior performance, achieving an accuracy of 0.9574 without data augmentation. Although ViT did not benefit from data augmentation, these techniques proved essential for enhancing the performance of AlexNet, ResNet-50, and EfficientNet. Our findings underscore the potential of deep learning methods for pest classification, offering valuable tools to help professionals maintain crop quality and value.

Authors: Meireles Pereira Santos Vinícius , Patrocinio Ana Claudia , Chaves de Souza Carvalho William , De Sousa Pedro Moises
Published: February 2025

Renal cancer is one of the 13 most frequent types of cancer in Brazil, primarily affecting individuals between 50 and 70 years of age, with around 12,000 cases and 4,000 deaths recorded in 2020. Early detection is crucial to prevent the progression of the disease, which can lead to kidney transplants, dialysis, or death. However, the lack of symptoms and screening tests make diagnosis difficult. This research proposes the use of Convolutional Neural Networks (CNNs) for the detection of renal cancer in CT images, classifying them as cancerous or normal. It is expected that the application of the obtained results can assist in early diagnosis, supporting healthcare professionals in providing faster and more accurate treatments and contributing to improving the patients' quality of life.

Authors: Vinicius de Moura Rodrigues Antonio , Barbosa Oliveira Roberta
Published: February 2025

Segmentation of skin lesions in dermoscopic images is a crucial step in diagnosing skin cancer, and Convolutional Neural Networks (CNNs) have emerged as powerful tools to address this challenge. This paper evaluated the effectiveness of two CNN models, TernausNet-16 and Mask R-CNN, in segmenting skin lesions and five of their attributes in the dermatoscopic images from the ISIC 2018 Challenge dataset. Jaccard Similarity Index (JSI) and Dice Similarity Coefficient (DSC) have been used as evaluation metrics. The results revealed that Mask R-CNN significantly outperformed TernausNet-16. The best model achieved 82.57% JSI and 84.76% DSC for lesion segmentation, and 42.86% JSI and 51.60% DSC for attribute segmentation when addressing attribute imbalance. Despite the longer training time, the results highlighted the potential of Mask R-CNN for improving the effectiveness of melanoma segmentation.

O presente artigo tem como objetivo apresentar as perspectivas gerais da política doméstica implementada por Dutra, Castello Branco e Bolsonaro, bem como, analisar as ações promovidas pelos três governos, no que diz respeito ao relacionamento do Brasil com os Estados Unidos. Para a realização do estudo foi utilizada coleta de dados documentais e revisão bibliográfica, como também, análise comparativa a fim de observar as semelhanças e diferenças das medidas empregadas pelos três presidentes. A partir das análises entre os governantes, observa-se que seus discursos e práticas foram similares, na medida em que presenciaram um momento de polarização da sociedade brasileira, e como efeito, buscaram a aceitação popular por meio da reorientação dos rumos da política. Esse cenário se reflete na política externa, com o direcionamento de relações para os Estados Unidos.
O MALE GAZE EM THE HOUSE THAT JACK BUILT
Authors: Almeida Manuella , Takakura Sandra Mina
Published: February 2025

The film is a type of media that has evolved in diversified ways throughout time. Some directors present their signatures on every production, allowing the audience to recognize their styles. Recently, Lars Von Trier’s signature on-screen has promoted heated debates. He challenged critics with his choice for controversial themes and intense use of external references, both literary and artistic. This paper aims at delving into Von Trier’s film The House That Jack Built (2018) to scrutinize the journey of a serial killer and his cruel crimes, focusing especially on the intermedial references and the masculine gaze. The notion of auteur, drawn by André Bazin (1957), studies on intermediality by Irina Rajewsky (2005) and Werner Wolf (2005), and cinematic gaze by Robert Stam (1992) and Todd Mcgowan (2003) compose the theoretical bases of this paper. This study shows that intermediality and the cinematic male gaze, fundamental elements of the director’s style, sustain the construction of his unique signature in the aforementioned production.

A produção poética de autoria feminina de meados do século XIX e início do século XX aponta para o despertar da mulher rumo à libertação das amarras sociais. Fazendo da escrita sua melhor companhia, as mulheres-escritoras oitocentistas reclamaram para sidireitos, entre eles entrar na esfera literária, espaço eminentemente masculino à época. Entre essas mulheres-escritoras que ousaram escrever, quando, segundo os preceitos vigentes que determinavam a escrita como função masculina, assim não deveriam agir, estão as poetisas Gilka Machado (1893-1980) e Laura Santos (1919-1981). No presente artigo, interessa-nos analisar como as mencionadas poetisas, em meio a uma sociedade alicerçada sob preceitos patriarcais, lograram tecer um discurso próprio, carregado de conotação erótica. Procurando conjugar os estudos sobre relações de gênero com os estudos sobre literatura e sociedade, pautar-nos-emos no método da crítica textual, privilegiando a análise integral dos poemas escolhidos. Para tanto, como aporte teórico principal, nos valemos das contribuições de Telles (1987), Paixão (1991), Foucault (2011), no que concerne ao imaginário feminino no século XIX, ao erotismo nos escritos de mulheres oitocentistas e ao discurso acerca da sexualidade na sociedade ocidental, respectivamente.
REPRESENTAÇÃO FEMININA A PARTIR DOS PASSOS DE LENIZA, PERSONAGEM DE A ESTRELA SOBE, DE MARQUES REBELO

Published: February 2025

Embora o nome de Rebelo tenha circulado entre os escritores da grande crítica literária (ANDRADE, 1974; COUTINHO, 1971, BOSI, 1972), desde a publicação de seu primeiro livro, Oscarina (1931), verifica-se o quase apagamento de estudos inerente à produção do autor dentro do cenário de estudos literários na contemporaneidade. Com o intuito de trazer lume ao nome do autor e, em específico, ao romance A estrela sobe, publicado em 1939, este artigo propõe-se a analisar o percurso da personagem central do romance, Leniza. Para tanto, por meio de uma pesquisa bibliográfica, revistam-se autores, tais como: Troian (2013); Wagner (2018); Waller (2008); Scholze (2002); Vidal e Alves de Aguiar (2002), a fim de buscar aspectos dentro da linguagem literária que permitam compreender Leniza como uma mulher à frente de seu tempo, com seus conflitos e desafios.
Ateliês do sexo, alcova edênica

Published: February 2025

O conluio entre os imperativos da carne e a receptividade da ficção provoca uma tensão, de cunho erótico, capaz de ludibriar o observador, lançando-o numa zona diegética tempestiva, que tampona, ilusoriamente, os buracos impostos pela realidade. A crueza de um alter-ego servo do prazer e os engodos de uma voz narrativa fecenina fornecem o "combustível" para a excitação e, ao mesmo tempo, para o declínio do corpo, o qual, de modo surpreendente, liberta-se dos grilhões do pudor e da inocência. Entrementes, o presente trabalho se infiltrará pelas entranhas de uma das pinturas série Paraíso, um compêndio telas da artista naif Val Margarida, no intento de aproximar, (im)possivelmente, instâncias que insistem em se desencontrar. Nas pinturas da Val Margarida, não à toa, a quebradiça malha que protege o humano, da lascívia que o habita, é, subitamente, desfeita, destruída pelos ataques adocicados de Thânatos, cujos suspiros e impropérios fazem aflorar o incauto Eros, que, impotente, subjuga-se à tortura e à dor. É latente a insurgência de vozes líricas complacentes, que, ora devotam cuidados ao inefável, ora tornam-se agentes que amaldiçoam e praguejam, num movimento de puro êxtase, em que a libido fere a folha, a tinta é abusada e o pincel, deslizando em semânticas, desenha o orgasmo. Seu cunho, herético por excelência, exaure o desejo, sacraliza o encontro fúnebre dos corpos e, sem cerimônia, profana a religiosidade de deuses e mortais. Debalde, a consciência ecoa em desespero, silenciando-se, sem êxito algum perante a efervescência sexual. Para tanto, valemo-nos de afamados e abjetos pesquisadores dos estudos erótico-pornográficos, tais como Georges Bataille e Eliane Robert Moraes.
sombra da morte

Instaurando uma narrativa ontológica que perscruta as transgressões da alma feminina, Lya Luft, ao apresentar protagonistas em pleno processo de individuação, evidencia alguns reflexos da face oculta da psique feminina. Considerando esse traço peculiar de sua produção, pretendemos, neste trabalho, mostrar como, em O quarto fechado (2004), ocorre o processo de individuação de Renata, a protagonista do referido romance. Como instrumento indispensável de leitura, recorreremos à contribuição da psicologia analítica jungiana, a qual nos permitiu compreender a obra em estudo como uma trama de caráter sombrio em que a Morte, personagem central, é a responsável pela imersão de Renata no mundo escuro de seu ser onde Sombra e Persona, dois dos arquétipos – que, frequentemente, mais influenciam o ego –, são postos em relevo, em um embate psíquico que indica a iminência do processo de individuação da protagonista ao final do qual Renata aprendeu a transformar o inconsciente em consciente e a superar as sensações de vazio, medo, depressão e fragilidade que tanto a atormentavam. Em síntese, todo esse processo de autoconhecimento lhe permitiu adquirir uma maior consciência e maturidade responsáveis pelo equilíbrio e pela resolução de seus conflitos.
Sibila de ferrões agudos: poesia e resistência em Augusto dos Anjos
Authors: Santos Derivaldo dos
Published: February 2025

O presente texto analisa o poema “O Negro”, de Augusto dos Anjos, sob o ponto de vista da resistência à ordem ideológica que reservou aos povos de origem africana o lugar da exclusão, negando-lhes o direito à voz e à vida digna. A análise tomou como fundamentação o pensamento crítico de Alfredo Bosi (1977; 2002; 2015), em particular sobre poesia e resistência, e do pensamento teórico e reflexivo acerca da relação entre lírica e sociedade, segundo a sistematização de Adorno (2003), Merquior (1997; 2013) e Holanda (2019). O objetivo principal foi examinar o poema, investigando suas tensões visíveis em relação ao processo histórico e social brasileiro, referente ao contexto de sua produção – início do século XX -, tomando-o como recusa e resistência aos discursos correntes de dominação e domesticação do escravo. Sob o ponto de vista da recusa, trata-se de uma lírica que se abre ao social conduzindo o leitor para além do cotidiano de aflição, “na direção de uma situação digna do homem” (ADORNO, 2003, p. 73), que é, ao mesmo tempo, resistir e refugiar-se do sistema de opressão.

Enobrecedor sabor veneno-vingança de uma maquiavélica assassina

Sendo o inconsciente coletivo dito por Jung (2008) como tendências inatas construídas e transmitidas de geração a geração desde os primórdios da humanidade, observamos o valor exuberante das manifestações de cunho oral para formação tanto do consciente, como do inconsciente coletivo. Através disso, quando Paulino (2010) afirma que a cultura popular detém um caráter atemporal e construtor dos hábitos e costumes de uma sociedade, analisa-se, pois, que a psicologia junguiana pode a considerar como um dos elementos formuladores da self do ser. A partir dessas reflexões, uma manifestação dentro desse arsenal imaginário é a literatura de caráter oral, advinda de vivências e contações de histórias que, posteriormente, foram registradas como estratégia de preservação de tal memória. Uma delas, em específico, são os romanceiros populares com gênese na tradição ibérica. Dessa forma, este estudo tem como objetivo analisar o romance “Veneno de Moriana” ou “El Veneno de Moriana” (1737) em uma das suas versões pioneiras no Brasil traduzida por Magalhães (1973), a partir de uma interpelação Junguiana, para observar o caráter promíscuo e vingativo de Juliana, protagonista do romance, através da categoria disposta pelo psicólogo como: arquétipo. Através dos dizeres teóricos de Belmonte (2020), Santos (2005), Jung (2008; 2011;2016) entre outros.
