Authors: Mikhaleva L. V. , Alekseev Yu. V.
Published: March 2023

A clinical case of the successful use of light-oxygen therapy is presented irradiation in the absorption spectrum of endogenous oxygen with its transfer to a singlet state in a patient with vulvar leukoplakia and lichen sclerosus. As a source of laser radiation, we used the domestic Super Sab diode laser with a wavelength close to 1265 nm (OOO New Surgical Technologies, Moscow), radiation power – from 0.9 to 1.2 W, power density – from 0.8 to 1.06 W/cm2, exposure dose – 200–250 J/cm2. The procedures were carried out 2 times a week with an interval of 3–4 days.As a result of the treatment (8 procedures), complete clinical remission was achieved.
Des monnaies locales pour le développement territorial ? Une application de la théorie de la base économique aux monnaies locales convertibles
Authors: Lafuente-Sampietro Oriane
Published: March 2023

Dans cet article, nous analysons le fonctionnement des monnaies locales convertibles (MLC) au travers de la théorie de la base économique. Nous mettons ainsi en évidence les mécanismes des MLC pouvant favoriser le développement de l’économie territoriale, notamment l’internalisation de la demande de leurs membres. Les utilisateurs des MLC ne représentent qu’une fraction des acteurs du territoire. Les MLC soutiennent donc le développement de sous-communautés spécifiques, mais dont la croissance peut transformer les économies territoriales. L’analyse des données de transaction numérique de la SoNantes et l’Eusko dévoile les sphères économiques empiriquement soutenues par les MLC. Ainsi, ces deux MLC françaises s’implantent essentiellement dans les secteurs domestiques et si, la SoNantes intègre des entreprises dédiées au soutien à des activités productives, les deux MLC irriguent majoritairement des activités de distribution et de consommation courante à destination des ménages. La transmission des recettes perçues par ces secteurs à des activités productives demeure faible, limitant le réel potentiel de développement économique des MLC.
Forecasting stock prices based on multivariable fuzzy time series
Authors: Liu Zhi
Published: March 2023

With the development of the stock market, the proportion of the stock assets in the asset structure of the residents increases rapidly. Therefore, the research on the prediction of stocks has great theoretical significance and application potential. A key point of researching stock prices is how to pick out the main factors. In this study, principal component analysis (PCA) is applied to find out the main factors which mainly affect the stock price. Then an improved cluster analysis algorithm is proposed to fuzzy the data, and a qualitative analysis method is given to find the most suitable prediction set from the multiple fuzzy sets corresponding to the current fuzzy set. We also extend the inverse fuzzy number formula to a more general form to get the predicted value. Finally, Xishan Coal and Electricity Power (XSCE) and Taiwan Futures Exchange (TAIFEX) time series are predicted, using the proposed multivariate fuzzy time series method. The results show that the prediction error is lower than that of the previous models. The proposed method produces better forecasting performance.

Published: March 2023

Burns constitute one of the most common injuries in the world, and they can be very painful for the patient. Especially in the judgment of superficial partial thickness burns and deep partial thickness burns, many inexperienced clinicians are easily confused. Therefore, in order to make burn depth classification automated as well as accurate, we have introduced the deep learning method. This methodology uses a U-Net to segment burn wounds. On this basis, a new thickness burn classification model that fuses global and local features (GL-FusionNet) is proposed. For the thickness burn classification model, we use a ResNet50 to extract local features, use a ResNet101 to extract global features, and finally implement the add method to perform feature fusion and obtain the deep partial or superficial partial thickness burn classification results. Burns images are collected clinically, and they are segmented and labeled by professional physicians. Among the segmentation methods, the U-Net used achieved a Dice score of 85.352 and IoU score of 83.916, which are the best results among all of the comparative experiments. In the classification model, different existing classification networks are mainly used, as well as a fusion strategy and feature extraction method that are adjusted to conduct experiments; the proposed fusion network model also achieved the best results. Our method yielded the following: accuracy of 93.523, recall of 93.67, precision of 93.51, and F1-score of 93.513. In addition, the proposed method can quickly complete the auxiliary diagnosis of the wound in the clinic, which can greatly improve the efficiency of the initial diagnosis of burns and the nursing care of clinical medical staff.
Sigmoidal dynamics of macro-financial leverage
Authors: Smirnov Alexander D.
Published: March 2023

Logistic sigmoids due to their flexibility seem to be natural candidates for modelling macrofinancial leverage behavior. The sigmoidal leverage transition towards its stationary value, which was driven by the yield spreads, could have replicated the dynamics of macrofinancial assets, debt and capital. The leverage transition, in its turn, has been a major factor in better balancing macrofinancial liabilities and assets. The sigmoidal leverage trajectories including their inflections and different phases were identified by a nonlinear transition function providing information necessary for steering the process towards its stable state. Solving the stationary Kolmogorov-Fokker-Plank logistic equation revealed that random leverage realizations might follow the gamma distribution. Parameters of its stationary probability density function, as well as the expected and the modal leverage, were dependent on the process variance and the yield spreads. Thus, the stochastic leverage behaviour reproduced a sequence of stylized phases similar to the observed in the US Treasuries market meltdown in 2020. In particular, larger yield spreads and smaller modal leverage signalled a "defensive" market response to sudden volatility increases. In addition, it was shown that the logistic leverage modelling could be helpful in the analysis of debt and money dynamics including some consequences of "minting a one trillion dollars coin".
¿Voto programático o evangélico? El apoyo electoral a la derecha radical en Brasil y Costa Rica
Authors: Sendra Mariana
Published: March 2023

Este artículo se pregunta hasta qué punto el apoyo electoral de los evangélicos a los candidatos de derecha radical está impulsado por preferencias de políticas, considerando tres dimensiones: socioeconómica, sociocultural y autoritaria. Se enfoca en los casos de Brasil y Costa Rica, dos países que comparten un mismo resultado político: la emergencia de dos candidatos de derecha radical (Bolsonaro y F. Alvarado) con alto éxito electoral, explicado, en parte, por un factor común: el apoyo de las iglesias evangélicas pentecostales. Utilizando datos de LAPOP 2018-19, testeamos el efecto de las policy-preferences dimensions como hipótesis alternativa al voto confesional y, además, analizamos si existe un efecto de refuerzo ejercido por las preferencias sobre la confesión religiosa. Encontramos que solo en Brasil los evangélicos más conservadores votaron en mayor medida por Bolsonaro, mientras que, en Costa Rica, los evangélicos apoyaron a F. Alvarado independientemente de su posicionamiento en la dimensión sociocultural.

Published: March 2023

The present study describes the population dynamics and life history parameters of the enigmatic tanaid Chondrochelia dubia collected in Paiva Beach, tropical coast of Brazil. The region was impacted by a large, unexpected oil spill from August to October 2019. Samples were taken monthly between July 2019 and July 2020 in beds of the red seaweed Jania capillacea. The abundance of individuals was negatively correlated with monthly rainfall, with higher abundances in drier months. There was an unexpected significant drop in abundance in September, possibly caused by contact with the crude oil, but the population recovered fully within two months. The parameters of the von Bertallanfy growth equation, calculated for the first time for the species, were Linf=5.26 mm; k=3.36 year–1; t0=0.0. Compared with other studies, the specimens are very small (2.04 ± 0.95 mm in length), females reach sexual maturity very early (L50=2.3 mm), and natural mortality is high (Z=M=5.77 year–1), indicating an opportunistic life strategy. This study reinforces the bioindication potential of C. dubia and the use of bootstrapped length-based methods to estimate key population parameters in small marine invertebrates.
Les plus anciennes gravures rupestres du Sahara central ?
Authors: Striedter Karl Heinz , Tauveron Michel
Published: March 2023

Dans les années 1960, F. Mori découvrit dans la Tadrart Acacus (Sud-Ouest libyen) un petit nombre de gravures rupestres qui ne pouvait être classé dans aucune famille connue de gravures, et qu’il qualifia d’« ichthyomorphes ». Au cours de recherches de terrain dans les années 1990 dans la Tadrart algérienne (prolongement de la Tadrart Acacus vers le sud), il a été retrouvé un nombre important de nouvelles gravures rupestres proches des « ichthyomorphes » de Mori et il semble désormais justifié de parler d’un faciès particulier de gravures rupestres du Sahara central. Ainsi que le montrent des superpositions, ces gravures précèdent les peintures de la période des « Têtes Rondes », et les observations géomorphologiques suggèrent de les dater vers la fin du Pléistocène.

Impacto do consumo de informação nas mídias sociais na percepção de desinformação no contexto eleitoral mexicano em 2021
Authors: De Elias Jessie , Muñiz Carlos
Published: March 2023

O surgimento e consolidação das mídias sociais como meio de obtenção de informações tem promovido o fenômeno da desinformação por meio da criação, produção e divulgação de informações falsas. Este estudo parte da hipótese de que a percepção da desinformação através dos media e das redes sociais está relacionada aos níveis de consumo de informações por meio dessas plataformas, principalmente em um contexto eleitoral. Para isso, foi aplicado um questionário nacional na conclusão das eleições federais mexicanas de 2021. De acordo com os resultados obtidos nas análises efetuadas, foi possível aceitar esta hipótese, o que denota o indubitável papel que a desinformação desempenha durante os processos eleitorais. Sendo uma linha de investigação relativamente nova, a literatura sobre o tema é limitada, pelo que é necessário continuar a aprofundar os efeitos que a desinformação gera nas atitudes políticas dos cidadãos.
Meconium Aspiration Syndrome: Analysis of Case Report
Authors: Akram Ali S Mohamed , H. Rajamohamed , S. Ravikiran , MF Thawfeeq Ahmad K , M. Porkodi , S. Vinoth Kumar
Published: March 2023

Introduction: The first stool of a newborn child is meconium. Meconium is a sticky material composed of denuded intestinal epithelium cells, bile acid, amniotic fluid, swallowed lanugo hair, digestive enzymes, water and mucus. Post-term infants are more likely to have meconium-stained amniotic fluid (MSAF). Meconium aspiration syndrome, a leading cause of severe illness and death in newborns, occurs in about 5 per cent to 10 per cent of births. Case study: A newborn male baby was admitted to the Neonatal Care Unit with the chief complaints of Term, vacuum extraction and thick MSAF and Respiratory Distress skin colour was found to be dark green in the chest and dorsal limb of the body. Breath sound was found to be abnormal with grunting sounds on examination with a stethoscope. The patient’s Clinical symptoms include the appearance of skin colour, and breath sound and Chest radiography shows the diagnosis of Meconium Aspiration Syndrome (MAS). The patient was treated with O2 through nasal continuous positive airway pressure, fluid management was based on daily body weight and antibiotics like ampicillin and gentamicin was administered at the time of admission. The Patients caretaker was advised to Kangaroo mother care and direct breastfeeding. Conclusion: Over the years, medication and care for newborns with meconium aspiration have evolved and changed. Prophylactic antibiotic therapy in MAS does not change the prognosis of patients. In newborns with extreme and recurrent hypoxemia caused by MAS, extracorporeal membrane oxygenation (ECMO) has been utilised as a last-resort therapy. Nevertheless, there are still several techniques for preventing and treating meconium aspiration syndrome; therefore research should continue to diminish illness and death caused by Meconium aspiration syndrome.

El uso de técnicas cuantitativas para la clasificación de segmentos poblacionales es una fase crítica para evaluar sus condiciones de materiales de existencia, información que sirve como input para los procesos de planificación de estrategias dirigidas a paliar la pobreza y la intervención discrecional de tales grupos, bajo los criterios de racionalidad económica e instrumental. En este artículo se construye un modelo de máquinas de soporte vectorial, entendido éste como un algoritmo de aprendizaje supervisado que proporciona un clasificador lineal no probabilístico con un superlativo nivel de precisión. De este modo, se segmenta una muestra de núcleos familiares residentes en Cartagena de Indias, en función de ciertas variables económicas y sociodemográficas. La obtención de los resultados analíticos refrenda el hecho de que los factores con mayor poder de discriminación entre los agentes económicos son el estatus laboral, la accesibilidad a servicios públicos y la renta percibida por los núcleos familiares. Por otra parte, se corrobora que las condiciones de vecindario y la recepción de transferencias monetarias corrientes tienen un poder clasificatorio reducido.

The aims of this study were to investigate nutritional value of coldpressed sunflower oil produced in the Republic of Serbia. Composition of fatty acids was determinated and, based on individual fatty acid content, nutritional indices are calculated. Tocopherol composition and total content of carotenoids and chlorophylls were investigated as well. The results indicate that examined oil is rich in essential linoleic acid and with excellent values of nutritional indices. Unfavorable n-6/n-3 ratio is caused by low n-3 fatty acids content which is characteristic for sunflower oil. Total tocopherol content was unexpected low while content of pigments was characteristic for this type of oil

Heat exchangers are one of the most frequently used elements in the process industry. Water is usually used as a heating fluid and often is not chemically prepared, i.e. it has bicarbonate, calcium, and magnesium, which make the water temporarily hard and form incrustations on the primary side of the heat exchanger. The paper shows a device for chemical cleaning of the heat exchanger without disassembling it and when the secondary side of the heat exchanger is actively working. Tests of the device in operation were carried out in the machine plant of the Tonanti Hotel in Vrnjačka Banja from 2021 to 2022, where it showed high reliability and complete independence in operation.
TEST COMPLETION TIME, SUBJECT SCORES AND ACADEMIC SELF-EFFICACY. HOW DO THEY RELATE?
Authors: Kihoro Muya Francis
Published: March 2023

Educators always endeavor to unravel the myriad of unexplained variables in learning environments. Examination taking is one such variable. Given the importance attached to examination results, educators seek answers as to why some students have shorter completion time than others and whether they end up scoring better than those who finish later. Is this phenomenon related to their levels of academic self-efficacy? This study set out to investigate the relationship between academic behavior confidence, test scores and test completion time. It was grounded on the self-efficacy theory by Albert Bandura. In an exam-taking situation, twenty-five early finishers and twenty-five late finishers were identified in a common unit examination in a public university in Kenya. They later filled out the Academic Behavior Confidence scale developed by Sander & Sanders (2019). The relationships between the completion time, the test scores on the common unit and their Academic Behavior Confidence scores were investigated using non-parametric approaches, specifically the Spearman’s rho and Mann-Whitney U test. Results show a significant difference between completion time and test scores. Paradoxically, there is no significant difference between completion time and ABC scores. However, there is a positive relationship between test scores and Academic Behavior Confidence scores. It is recommended that educators should use mastery experiences, verbal persuasion and vicarious experiences to enhance Academic Self-efficacy, which may, in turn, improve test scores.

INVESTIGATION OF STUDENTS’ ATTITUDES TOWARD MATHEMATICS IN MIDDLE SCHOOLS IN SAUDI ARABIA
Authors: Alharthi Majed Saeed
Published: March 2023

Many students in Saudi Arabia complain that they achieve poor results in mathematics and appear to have a negative attitude toward the subject. The current study, therefore, investigates students’ attitudes towards mathematics, using a mixed method approach, in 13-16 years old students from the intermediate level of education. The age was important because this period is thought to be crucial to the formation of lasting attitudes and opinions. The first main research question, the study aims to address is therefore, “What are students’ attitudes towards mathematics in Saudi middle schools?” The study also aims to explore gender issues using a second research question, “Is there any significant gender difference in students’ attitudes towards mathematics?” The survey was conducted in two government-run middle schools in Saudi Arabia, one boys’ school and one girls’ school, because Saudi Arabia has an exclusively single-sex education system. 180 participants (90 boys and 90 girls) were asked to complete a questionnaire to show their views about mathematics. Qualitative and quantitative data were collected at the same time, but the analysis of each type of information was conducted separately to enable the full picture to be understood. T-test was used to explore any gender differences. The main findings were that both male and female students in two Saudi middle schools show a positive attitude towards mathematics, with female students being slightly more positive than males. The factors which affect attitudes towards mathematics in both genders include the usefulness of mathematics in everyday and future life and career, the teacher, enjoyment of mathematics and the difficulty of the subjects. Girls’ attitudes towards mathematics were also affected by the influence of social media personalities and internet teachers.

EXAMINING SCHOOL AND COMMUNITY PREPAREDNESS FOR TRANSITION OF YOUNG ADULTS WITH INTELLECTUAL DISABILITY FOR INDEPENDENT LIVING IN SELECTED COUNTIES, KENYA
Authors: Makumi Mary Wangui , Karugu Geoffrey , Runo Mary , Muthee Jessina
Published: March 2023

Despite the Government of Kenya’s commitment to provide education for all its citizens including those with disability, those with mild and moderate ID seem not to proceed for further education, training, employment and settling in their community after special or primary school. The main goal of the study was to examine the school and community preparedness for transition of young adults with mild and moderate intellectual disability for independent living in Kiambu and Murang´a counties, Kenya. The specific objectives of the study were investigated barriers to successful transition of young adults with intellectual disability for independent living and to establish the levels of independent living among young adult graduates with intellectual disability within the last five years in Kiambu and Murang’a counties. The study adopted descriptive research design which utilized both quantitative and qualitative research approaches. Target population was 239 headteachers, 405 SNE teachers, 1,200 young adults in school, 600 young adult graduates and 199 opinion leaders in 9 special schools and 230 special units. Purposive sampling method was used to select 120 young adult learners, 60 graduate, 30 headteachers and 20 opinion leaders while simple random sampling method was used to select 48 SNE teachers to participate in the study. This gave a total of 278 study respondents. Questionnaires and interview guides were used to collect data. The study established that dual diagnosis, assistance of taking medication independently, medical condition, running or wandering from home and loneliness were the main barriers to independent living for adult learners with ID. The study found out that the level of independent living was low among individuals with intellectual disabilities in the schools and units of study. After graduating from special schools and units, majority of learners with ID went back home and they were not engaging in any activity after school. Among the few who were engaging in activities after school, most of them were doing beadwork and weaving, hairdressing, farming, carpentry and dressmaking. Others were employed in their former schools/units as security guards. Graduation of the learners with intellectual disability was not considered as a very relevant process and hence most schools were not given any certification to learners with ID. This is despite most of the teachers and headteachers reporting that learners with ID graduated after learning the required skills. The study recommends that; the government through the Ministry of Education should create a special class in secondary schools for those in the borderline; provide policy that Ministries, NGOs, private sectors among others should employ young adults with ID to promote independent living.

MACROSTRUCTURES AND RHETORICAL MOVES IN COMPUTER ENGINEERING RESEARCH ARTICLES
Authors: Seiradakis Emmanouela V.
Published: March 2023

Genre analysis has offered us valuable insights into the rhetorical organization of different genres. Regarding the research article (RA) genre in engineering, previous move-based works have shown that disciplinary variation is evident, especially across computer engineering (CE) sub-disciplines which often showcase unique rhetorical structures and patterns due to the newness of the field. Using Swales’ seminal move analysis approach (1990) this paper presents a synthesis of move-based works that have explored RA textual structures in CE sub-disciplines. The discipline-specific A-IMRD move/step frameworks and patterns presented in this paper can form the foundation of research-based English for Academic Purposes (EAP) pedagogies and teaching materials tailored to the needs of CE students in academic writing courses.

FOSTERING INTERCULTURAL AWARENESS IN ONLINE EAP CLASSROOMS USING THE REALIST SOAP OPERA GENRE
Authors: Seiradakis Emmanouela V.
Published: March 2023

This qualitative work attempts to investigate the viability of using the British realist soap genre as an authentic cultural resource for raising the intercultural awareness of Greek EFL university students about social issues relevant to their age. Five students participated in this study. Participants watched thirteen online episodes of the British realist soap EastEnders for one academic semester within their EAP courses and completed weekly reflective tasks based on the storylines of each episode. Data were gathered from semi-structured interviews. The findings garnered suggest that British realist soap operas could be exploited in order to foster intercultural awareness processes of Greek EFL university students. This small-scale study highlights the need for further research in the field of intercultural awareness within the EAP context. Additionally, it is proposed that EFL teachers in Greece and elsewhere invest more in intercultural training and use authentic materials more often in the EAP classroom.

Published: March 2023

Increasing rates of mental health problems among students and the reluctance of students to seek help in times of crisis are of great concern. This study aimed at determining the mental health seeking intentions and the barriers to mental health seeking intentions among students at Mulungushi University. An analytical cross-sectional quantitative design was used as a research design. A self-administered questionnaire adapted from 3 validated tools namely; General Help-Seeking Questionnaire (GHSQ), Perception of Stigmatization of Others for Seeking Help Scale (PSOSH) and Barriers to Access Care Evaluation (BACE-3) was used to collect data. 137 nursing and pharmacy students were randomly selected after meeting the inclusion criteria. SPSS version 23 and binary logistic regression were used for data analysis. The results of the study showed that mental health seeking intentions were weak, (69%) of students indicated that they were unlikely to seek help. Further, university sources of help were the least preferred by students, (60 %) of students indicated that they were unlikely to seek help from university-based sources. The study also showed that stigma was associated with poor mental health seeking intentions (OR=3.190, CI=0.8-11.339, P=0.041), students who were perceiving stigma were 3.19 times less likely to seek help than those who were not perceiving stigma. Although barriers to care showed no significant effect at a 5% level of significance, the odds showed that those who perceived barriers to access care were 1.41 less likely to seek help compared to those who were not perceiving barriers to access care. (OR=1.418, CI=0.623-3.230, P=0.404). The study also revealed that there was an association between gender and mental health seeking intentions. (OR=0.90, CI=0.3826-2.137, P=0.003), females showed stronger intentions to seek help seeking than males. Based on these findings, the study recommends that efforts should be channeled towards overcoming stigma and site-specific barriers to access care which are contributing to poor mental health seeking intentions among students. Further, special consideration must be placed on males through these interventions since they showed lower health seeking intentions than females.

Neo-armoriais? Música armorial, influências e repercussão nas produções artísticas atuais
Authors: Santos Marília
Published: March 2023

Há mais de 52 anos, em 18 de outubro de 1970, era lançado na igreja de São Pedro dos Clérigos em Recife o Movimento Armorial. O movimento, liderado pelo escritor e dramaturgo Ariano Suassuna, e composto por artistas e intelectuais nordestinos, tinha como principal objetivo criar uma arte erudita brasileira. Para isso, baseava-se no barroco ibérico e nas culturas populares do interior da região Nordeste do Brasil. Após mais de meio século desde o seu lançamento, ouve-se falar em armorial contemporâneo, pós-armorial e neo-armorial. Esse artigo tem como objetivo apresentar uma discussão sobre música armorial e a possível existência de um neo-armorial na atualidade. Para isso foram realizadas entrevistas com músicos que integram grupos como o SaGRAMA, o oQuadro e o Quarteto Encore, assim como com o artista Antúlio Madureira.

Abstract. The objective of this study was to analyze the perceived physical literacy of high school students in northern Mexico. A Likert-type questionnaire (Sum et al., 2018) was applied to 2,487 schoolchildren (1,618 female and 869 male) through Google forms. The reliability of the questionnaire shows a Cronbach's alpha of (0.842). Men are perceived as having better attitudes and skills in sports, with greater confidence to participate in physical activities and being able to self-assess their health related to physical condition, than women. On the other hand, only 31.6% of those surveyed consider that they have the ability to function socially during physical and/or sports activities. High school students do not feel comfortable to practice physical and sports activities, as well as to function socially, according to the perceptions presented in this study, these results may be useful for physical educators to promote physical literacy in high school students.

Essa pesquisa teve como objetivo compreender e analisar os processos de escolha dos estudantes pelos cursos técnicos concomitantes ou subsequentes ao ensino médio e pelo IF Sudeste MG – Campus Muriaé e as perspectivas de futuro. Para a discussão teórica utilizou-se o referencial bourdieusiano no âmbito da Sociologia da Educação. A operacionalização da noção de campo permitiu delimitar o IF Sudeste MG como um campo social, constituindo um espaço de luta, onde cada campi da instituição se tornou um subcampo que compõem esse jogo social e a noção de habitus possibilitou, por meio da investigação dos percursos social e escolar, interpretar os processos de escolha do curso e do estabelecimento de ensino e as perspectivas de futuro dos estudantes. A pesquisa se caracterizou como qualitativa e os dados foram obtidos mediante análise documental e entrevistas semiestruturadas com seis estudantes que ingressaram no IF Sudeste MG através do Processo Seletivo 2020/1. Estes alunos foram divididos em dois grupos de acordo com a modalidade de ingresso: GRUPO 1 – CONCOMITANTE e GRUPO 2 - SUBSEQUENTE. Concluiu-se que a escolha do curso técnico concomitante ou subsequente ao ensino médio ocorreu pela necessidade de certificação para o mundo do trabalho. Além disso, observou que os estudantes do GRUPO 1 – CONCOMITANTE escolheram por “eliminação” dentre as opções de curso ofertadas (Eletromecânica, Meio Ambiente e Secretariado) e que as características do estabelecimento de ensino pesaram para a decisão de ser fazer um curso técnico. As expectativas de futuro relacionadas ao mundo do trabalho e à carreia no ensino superior destes alunos, se distanciaram da formação técnica realizada no IF Sudeste MG – Campus Muriaé. Em contrapartida, os alunos que compuseram o GRUPO 2 – SUBSEQUENTE escolheram o curso técnico em função da necessidade de qualificação, visando melhorias nas condições de trabalho que ocupavam. As expectativas de futuro deste grupo se alinharam com a formação técnica realizada. Por fim, a escolha do estabelecimento de ensino, ocorreu principalmente pelos estudantes terem um repertório de escolha limitado, restrito à instituição que foi o lócus da pesquisa, reforçando a origem social de camadas populares e com baixos níveis de capital econômico, cultural e social acumulados.

Published: March 2023

A evasão é um fenômeno contínuo no sistema educacional de qualquer país. No Brasil, a preocupação com esta problemática iniciou nos anos 1940. A massificação das universidades públicas no Brasil trouxe as camadas excluídas para seu interior. A entrada destes estudantes já ocorria através de ações afirmativas feitas pelas universidades, mas foi o Sistema de Seleção Unificada (SiSU) e a Lei n. 12.711/2012 (Lei de Cotas) que estabeleceram critérios válidos para todas as instituições da rede federal de ensino superior. Com isso, a evasão toma nova roupagem, tornando um campo fértil para pesquisas. Neste sentido, essa pesquisa procura conhecer, descrever e analisar os processos de evasão do curso, reorientação da escolha do curso superior e integração dos estudantes da Universidade Federal de Viçosa (UFV), selecionados no SiSU 2018, com pontuações elevadas no ENEM. A base teórica é ancorada pela Teoria de Integração do Estudante (TIE) de Tinto (1993), pelas análises das desigualdades no interior da universidade propostas por Boudon (1981) e Bourdieu (1998), além de versar sobre o ofício do estudante na perspectiva de Coulon (2008). O lócus da pesquisa foi a Universidade Federal de Viçosa (UFV). Sua natureza é descritiva e a abordagem é quantitativa, a partir de dados secundários da Pró-Reitoria de Ensino da UFV. A amostra utilizada contempla 460 estudantes, sendo os 5 primeiros colocados na ampla concorrência e nas modalidades de cota no SiSU 2018 que ainda estão matriculados na UFV. Os resultados mostram que os cursos de menor prestígio são mais afetados pela evasão, que a reorientação da escolha de curso é mais comum entre estudantes da ampla concorrência, especialmente do sexo masculino. As mulheres negras possuem notas menores na graduação, mostrando a perpetuação do racismo estrutural e da desigualdade de gênero. Outro achado diz respeito aos egressos da rede federal, que são aqueles que mais reorientam suas escolhas, seguidos pelos alunos da rede privada. A saída de cursos de alto prestígio para outros de menor, bem como o inverso foram analisadas indicando que a reorientação de escolha acompanha a preparação para um novo vestibular e a redefinição do projeto destes estudantes.

Bu çalışmada; nonarteritik iskemik optik nöropatili olguların peripapiller retina sinir lifi tabakası kalınlığını ve optik diskin morfolojik değişiklerini optik koherens tomografi ile benzer yaş grubundan oluşan kontrol grubu ile karşılaştırmayı amaçladık. Çalışmaya Göz Hastalıkları Anabilim Dalı’nda nonarteritik iskemik optik nöropati tanısı almış 42 olgunun 50 gözü ve 50 normal olgunun 50 gözü dahil edildi. Nonarteritik iskemik optik nöropatili olgu grubunda %80.96’sı hipertansiyon hastasıyken, kontrol grubunun %52.00’sinde hipertansiyon mevcuttu. Nonarteritik iskemik optik nöropatili olgu grubunun, total, yarı alan ve sektöryel peripapiler retina sinir lifi tabakası kalınlığı kontrol grubuna göre anlamlı derecede ince bulundu. Sinir lifi tabakasındaki incelmenin en belirgin olduğu kadran %40.75 oranı ile üst kadrandı. Optik disk incelemesinde iki grup arasında ortalama cup/disk oranları birbirine benzerdi. Optik disk alanı nonarteritik iskemik optik nöropatili grupta 2.23±0.89 mm2 olup, kontrol grubunda 2.75±0.52 mm2 olarak bulundu. Nonarteritik iskemik optik nöropatili grubun optik disk alanı ortalaması istatistiksel olarak anlamlı şekilde daha küçük olarak saptandı (p=0.042). Nonarteritik iskemik optik nöropati geçirmiş olgularda optik koherens tomografi ile saptanan, özellikle üst kadranda lokalize belirgin peripapilller retina sinir lifi tabakası incelmesi ve optik disk alanının küçüklüğü nonarteritik iskemik optik nöropati tanısında yardımcı yöntem olarak kullanılabilir.

Follicular lesion of undetermined significance (FLUS) is defined in the same Group III with the atypia of undetermined significance according to Bethesda Classification but these subgroups have different malignancy rates and tumor characteristics according to the studies. In this study, the aim was to evaluate the preoperative clinicopathologic features of the patients with cytological Bethesda Category III/FLUS thyroid nodules. The 44 patients were divided into two groups based on fine needle aspiration cytology (FNAC) results as benign (pB) and malignant (pM) and compared the preoperative clinical, ultrasonographic findings and FNAC results of two groups. According to the univariate analyses the presence of hiopechogenicity and presence of microcalcification are found to be significantly higher in malignancy (p<0.05 for all). Also, the presence of microcalcifications (p=0.048), and hypoechogenicity (p=0.014) were found to be independent risk factors for malignancy according to logistic regression analysis. In patients with FLUS, it should be remembered that the incidence of malignancy increases and treatment should be considered in the forefront of surgery instead of recurrent FNAC in the presence of hypoechogenicity and microcalcification in ultrasonography, and in patients with nuclear membrane irregularity according to FNAC.

In this study, the effect of progesterone use on biomarkers due to abortion complaints in aneuploidy screenings was investigated. Two hundred seventy-six singleton pregnant patients with threatened abortion were enrolled in this retrospective study. The treatment group consisted of patients who received oral, vaginal, or intramuscular progesterone (n=137) while the control group received no progesterone (n=139). The results of the double and triple screening tests of the study groups were compared. Nuchal translucency measurements and pregnancy-associated plasma protein-A (PAPP-A), (MoM) values were significantly lower in the group that received treatment with progesterone compared to the control group (p=0.009 and p<0.001, respectively). Beta-human chorionic gonadotropin (βhCG), (MoM) and alpha-fetoprotein (MoM) were found to be statistically significantly higher in the group receiving oral progesterone treatment compared to the group receiving other types of progesterone treatment (p=0.032 and p=0.001, respectively). The PAPP-A was found to be significantly lower in the oral treatment group (p=0.001). It was also significantly lower in the hydroxyprogesterone caproate treatment group (p=0.013). In the vaginal progesterone treatment group, βhCG was significantly lower (p=0.036) than that in oral treatment group. The study showed that there is a relationship between different progesterone administration routes and fetal aneuploidy screening markers.
Melanoma Skin Cancer Classification via Region-Aware Hierarchical Feature Aggregation
Authors: Kim Kyungryun
Published: March 2023

Melanoma is a type of skin cancer with the highest risk of death. It is critical to identify these early, as the chances of survival significantly drop after stage 2 melanoma. The use of many technologies has lessened this risk but is still limited when correctly identifying malignant ones. Classifying malignant skin cancers is difficult for the following reasons: the shapes and sizes of melanomas are irregular. It is also challenging to visually distinguish between melanomas and non-melanoma regions. The performance of the previous research is based on the depth of the networks. This has a significant trade-off as using more layers adds to the computational cost of the process. Also, their methods use melanoma segmentation as an auxiliary input to the classification network. Thus, the performance of the classification significantly drops when the segmentation task fails. To address this issue, I propose a novel melanoma classification network that uses hierarchical feature aggregation with an attention mechanism. The overall architecture of the proposed network is as follows: The melanoma feature extractor takes the melanoma image as input and produces the image feature related to melanoma. The second module, the attention network, takes the same melanoma image and outputs the attention map which provides the melanoma feature extractor with feature-level regions of interest. The proposed network achieves an accuracy of 82.7% on the melanoma detection dataset which is publicly available online. Throughout the experiments, I have shown that the proposed method outperforms the previous state-of-the-art methods.
