Análise do insucesso escolar no ensino secundário geral
Authors: Silvestre Januário Biché Daniela 
Published: May 2024

Este artigo resulta de uma reflexão em torno do insucesso escolar e visa analisar as principais causas e consequências do insucesso escolar no ensino secundário geral na África Subsariana e em Moçambique. A pesquisa se configurou como um estudo teórico, a metodologia para a abordagem do trabalho consistiu na revisão bibliográfica de natureza qualitativa. Os resultados do estudo mostram-nos que o fenómeno é bastante complexo: No período analisado (2012, 2014, 2016 e 2018) a pesquisa constatou que houve maior desistência na 10ª classe do que na 12ª classe e, em 2018, desistiram menos alunos em ambas as classes relativamente a todo o período analisado. As causas de insucesso escolar são: abandono escolar de alunos antes da conclusão do ciclo, reprovações por diferença de idade cronológica e o nível escolar, falta de materiais pedagógicos, métodos e estratégias de ensino e aprendizagem usados pelos professores, problemas de aprendizagem, a falta de motivação, a baixa auto estima, os factores sócio económico, culturais, étnicos, influência do meio ambiente onde vive o aluno, condição financeira, a etnia e o baixo nível de educação dos pais tem um peso significativo no insucesso escolar. O insucesso escolar penaliza o jovem e a sociedade, porque a sua contribuição para diversos projectos do Estado, como a educação, os mesmos ficam inviabilizados.

Autoimmune thyroid disorders (AITDs) include a variety of inflammatory conditions affecting the thyroid gland, with Graves' disease (GD) and Hashimoto's thyroiditis (HT) being the most commonly seen types. Autoimmune thyroid illnesses often include the existence of antibodies against thyroid peroxidase (TPO), thyroglobulin (Tg), and thyroid stimulating hormone receptor (TSHR). We specifically targeted recently diagnosed adult patients with Graves' disease (GD), Hashimoto's thyroiditis (HT), and those with normal thyroid function as controls. The study looked at and compared different groups' levels of anti-TG antibodies, anti-TPO antibodies, and anti-chlamydia antibodies in the blood, as well as several clinical and biochemical markers, such as thyroid function tests. We analyzed data from a cohort of 60 patients diagnosed with Hashimoto's thyroiditis (HT), 60 patients diagnosed with Graves' disease (GD), and 60 healthy individuals serving as controls. The study found a strong link between having anti-TPO Abs and having Hashimoto's hypothyroidism (63.3%) and Graves' hyperthyroidism (86.7%). In the groups without anti-TPO Abs, Hashimoto's hypothyroidism was found in 36.7% of people and Graves' hyperthyroidism was found in 13.3% (P<0.03). Anti-thyroid peroxidase antibodies (anti-TPO Abs) are found in 86.7% of people with Graves' disease, which is more than the 63.3% of people with Hashimoto's disease who have these antibodies. There is no significant link between the percentage of people who have anti-TG antibodies and either Hashimoto's hypothyroidism (96.7%) or Graves hyperthyroidism (90%), according to the study. The significance level was set at P = 0.143. This is in comparison to the percentage of negativity in Hashimoto's hypothyroidism (3.3%) and Graves's hyperthyroidism (10.0%). The study showed how the groups were spread out based on the presence of Chlamydia trachomatis IgG antibodies. Chlamydia trachomatis IgG antibodies were much more common in people with Hashimoto's hypothyroidism (42) and Graves hyperthyroidism (26) than in the control group (0) (P<0.01).

The objective of this study is to determine the perception of female students of the polytechnic of Ibadan, Oyo State, towards cervical cancer and preventive. A cross-sectional study design was used to determine the above objective. The survey included 429 female students who lived on the Polytechnic Ibadan campus. A systematic sampling technique was used to choose 210 rooms out of a total of 420 rooms, and all of the selected rooms' occupants were questioned under the premise that there were two people in each room. Data were gathered using a self-administered questionnaire that had been pretested. Respondents with one or more risk factors were classified as being at a higher risk for cervical cancer and those with no risk factors as being at a lower risk. Data was analyzed using descriptive statistics and Chi square test at p<0.05.
Mean age of respondents was 24.2±3.7 years. More than half (60.3%) had good knowledge about cervical cancer and 55.1% had a good perception of cervical cancer. The identified risk factors were sexual debut before the age of 18 years (25.1%) multiple sexual partnering (11.6%), unprotected sexual intercourse (59.2%) and positive family history of cervical cancer (2.2%). Majority of the respondents (96.9%) were at a higher risk for developing cervical cancer. Few respondents (8.0%) had ever heard of the pap smear test and the major sources of information were the internet (33.3%) and hospital (25%). The uptake of pap smear test was low (1.8%). Majority of the respondents (71.9%) were not aware of where the pap smear test could be done. Only 4.7% were willing to receive the human papilloma virus (HPV) vaccine, while 5.1% were willing to do a pap smear test. The major reasons cited for not wanting to do the pap smear test was lack of perceived need for the test (13.4%) and financial constraint (1.5%). Respondents who were 25 years and below and single were more likely to have a good perception of cervical cancer. Those aged <30 years (OR 1.39, 95% CI 0.34-5.66), single (OR 1.07, 95% CI 0.45-2.50), those from faculty of science (OR 1.22, 95% CI 0.57-2.58) and those that had low risk score (OR 2.66, 95% CI 0.54-12.98) were likely to have a good perception of cervical cancer.
Even though respondents had a fair amount of awareness about cervical cancer, they nevertheless exhibited significant behavioral risk factors for the condition. The pap smear test had very poor awareness and uptake. Therefore, it is necessary to develop health communication initiatives that would motivate tertiary students to apply their learning to prevent cervical cancer

DE-CIFRANDO ATRAVESSAMENTOS PARA PRODUZIR VIDÊNCIAS E EVIDÊNCIAS NA PRÁTICA DOCENTE
Authors: Gonçalves Santos Maria da Glória 
Published: May 2024

O presente artigo tece considerações sobre possíveis manifestações espontâneas que podem ter ocorrência nas práticas docentes, tais como expressões, gestos ou atitudes surpreendentes tanto por parte do docente tanto por parte dos discentes e que podem fazer emergir vivências do passado, da história psíquica desses atores na sala de aula ou precipitar ocorrências futuras (im)previsíveis, caracterizando atravessamentos do simbólico desses sujeitos, podendo ser extremamente valiosas ou perturbadoras para o processo pedagógico em andamento. Esses aspectos da diversidade na formação docente e no exercício da docência levaram à reflexão sobre o 18º Interculte, como um desafio de decifração da temática e um exercício de propor novas discussões, tendo como base não apenas os conteúdos dos componentes curriculares, mas também os conceitos de inclusão, igualdade e diferença, com o compromisso ético de cada profissional, da Instituição e de cada família, na construção de um novo tempo.
PALAVRAS-CHAVE: gesto espontâneo; vidências; diversidade; inclusão; Formação docente.

At the Heart of the Mothercrystal: Final Fantasy XIV’s Approach to Localization and Lore as a Virtual Contact Zone
Authors: Vichot Rhea 
Published: May 2024

<p>Virtual worlds by nature of their persistence and ability to have multiple simultaneous users in the same space can act as contact zones, defined by Mary Louse Pratt as a "social space where disparate cultures meet, clash, and grapple with each other, often in highly asymmetrical relations of domination and subordination," (1991, p. 34). One affordance of virtual worlds in constructing the contact zone is the ability for the developer to use localization to bridge language gaps between a user and the virtual world and, to some extent, between players who have a shared understanding of the virtual world. This understanding extends to the properties of objects and locations and any narrative lore or background in the world. However, localization can be a double-edged sword, with choices in translation and localization leading to confusion among virtual world users and conflict between users and developers. </p><p>Language impacts two aspects of the virtual contact zone. For one, players communicate using languages they are proficient in, using whatever affordances are available in the interface and paratextual platforms, such as the official forums and social mediaplatforms like Reddit and Tumblr. For another, the world itself is awash in language. That text manifests itself in gameplay elements from user abilities and item names to more narrative elements such as character names, dialogue, and written story and worldbuilding elements. These textual and narrative components, called "lore," are essential in contextualizing virtual spaces. Lore helps build the virtual world beyond the actual mechanics and interactions within a virtual space. Lore gives users a sense of not just place but of geography, not just time, but of history, and not just context for players but their place within the story of the virtual world. Lore offers players motivation for playing in addition to traditional gameplay motivators such as exploration, achieving, socializing, and defeating enemies or other players (Yee, 2006; Bartle, 1996) to interact with the world. </p><p>This paper focuses on the case of Final Fantasy XIV: A Realm Reborn (FFXIV), an MMORPG initially released in 2013, its production, approaches to localization,and how it contributes to building a "virtual contact zone." In looking at specific instances where controversies in translation and localization led to confusion and conflict among the participants and developers of the game, this case study illustrates the role of localization in games beyond translation and acculturation. Localization not only serves as the linguistic bridge among members of the contact zone but, in the case of online games where world-building and narrative are important aspects for immersion and play, creates shared experiences and understandings of that virtual world among all members of the virtual contact zone.</p>

Assessment of the impact of 3D printed water-lubricated cutless bearings material on vibration parameters.
Authors: Blaut Jędrzej 
Published: May 2024

The tested bearings were subjected to equal loads and rotational speeds, using water as the lubricant. Analysis showed that they achieved the best vibration damping at lower speeds, between 600 and 1100 rpm. Comparative studies of bearings made of different materials, such as available on the market bearings made of rubber, bearings printed with a 3D printer from PETG, PLA, ABS or Tribo filament materials, revealed differences in their vibration damping ability and operational stability. Conclusions from the study suggest that higher vibration acceleration may increase the radius of the trajectory, which may affect the function and performance of the bearings. The importance of the operational stability of water-lubricated plain bearings cannot be assessed solely on the basis of the RMS of vibration acceleration or trajectory radius. Both of these parameters are crucial from the user's point of view, especially in the context of various applications such as electric boats.

Salinity stress is one of the factors limiting seed emergence and seedling development in sunflower at New halfa scheme in East of Sudan. A study of two factors pots experiment was conducted during winter season of 2019 to evaluate germination indices and seedling growth characters of maize seeds under salinity stress with varying concentrations of synthetic growth regulator namely (GA3). The experiment was laid out according RCBD with three replications. Treatments consisted of five levels of salinity (0, 0.5, 1.0, 1.5 and 2% ) designated as Na0, Na0.5, Na1.0 ,Na1.5 and Na2.0, and four levels of GA3 were (0, 50,75 and 100 p.pm) designated as G0, G50, G75 and G100, respectively,. The studied parameters include germination indices; daily germination (MDG), daily germination speed (DGS), final germination percentage (FGP), mean emergence time (MET), mean Energy of germination (EE), emergence index (EI), coefficient of uniformity of emergence (CUE) and vigour index (SVI). Also, seedling fresh and dry weight, shoot length and root length were measured, and the shoot/root ratio was calculated. The negative effects of salinity stress significantly decreased germination indices and seedlings growth characters in a dose dependent manner. The results showed that, application of GA3 at medium levels concentration (specify those doses) increased all studied parameters. In conclusion, application of high Ga3 levels enhanced all germination indices and seedlings growth characters while high salinity levels reduced these traits of maize seeds. Such result has made the base for further study that should be conducted in different seasons with different growth regulators involving different parameters of other crops.

AbstractImproving the functional stability of shape memory alloys (SMAs), which undergo a reversible martensitic transformation, is critical for their applications and remains a central research theme driving advances in shape memory technology. By using a thin‐film composition‐spread technique and high‐throughput characterization methods, the lattice parameters of quaternary Ti–Ni–Cu–Pd SMAs and the thermal hysteresis are tailored. Novel alloys with near‐zero thermal hysteresis, as predicted by the geometric non‐linear theory of martensite, are identified. The thin‐film results are successfully transferred to bulk materials and near‐zero thermal hysteresis is observed for the phase transformation in bulk alloys using the temperature‐dependent alternating current potential drop method. A universal behavior of hysteresis versus the middle eigenvalue of the transformation stretch matrix is observed for different alloy systems. Furthermore, significantly improved functional stability, investigated by thermal cycling using differential scanning calorimetry, is found for the quaternary bulk alloy Ti50.2Ni34.4Cu12.3Pd3.1.
Use of Reversal Nanoimprinting of Nanoparticles to Prepare Flexible Waveguide Sensors Exhibiting Enhanced Scattering of the Surface Plasmon Resonance

Published: May 2010

AbstractA flexible surface plasmon resonance (SPR)‐based scattering waveguide sensor is prepared by directly imprinting hollow gold nanoparticles (NPs) and solid gold NPs onto flexible polycarbonate (PC) plates—without any surface modification—using a modified reversal nanoimprint lithography technology. Controlling the imprinting conditions, including temperature and pressure, allows for the fine adjustment of the depths of the embedded metal NPs and their SPR properties. This patterning approach exhibits a resolution down to the submicrometer level. A 3D finite‐difference time domain simulation is used to examine the optical behavior of light propagating parallel to the air/substrate interface within the near‐field regime. Consistent with the simulations, almost an order of magnitude enhancement in the scattering signal after transferring the metal NPs from the glass mold to the PC substrate is obtained experimentally. The enhanced signal is attributed to the particles' strong scattering of the guiding‐mode waves (within the waveguide) and the evanescent wave (above the waveguide) simultaneously. Finally, the imprinting conditions are optimized to obtain a strongly scattering bio/chemical waveguide sensor.
