Discussion on the Integrated Development Path of Financial Accounting and Management Accounting
Authors: Yuan Xingmeng , Tang Long
Published: June 2023

The gradual development of economy and rapid progress of science and technology have promoted human society to step forward into the era of digital economy, and then promoted the transformation of financial accounting function based on accounting and supervision to management accounting function based on value creation and value increment. However, both financial accounting and management accounting are branches of the accounting discipline, and the professional knowledge of a single branch is slightly insufficient to solve problems in a certain field. Only by combining and integrating the knowledge of multiple branches, and analyzing and solving problems from multiple perspectives can enterprises achieve sustainable development. Therefore, in combination with the background and direction of industry development in the era of digital economy, this paper analyzes the necessity of the integrated development of financial accounting and management accounting based on the functional positioning of enterprise financial accounting and management accounting, and discusses the integrated development mode of financial accounting and management accounting from the aspects of goal orientation, platform construction and content construction. And then put forward the two in the concept of mutual integration, content mutual penetration, system framework, technical personnel mutual integration and other aspects of the feasible path, in order to improve the accounting staff's business ability and comprehensive quality, conform to the market demand and the development of The Times.

Authors: Solomonian Leslie , Crawford Lachlan , Mohmand Shakila , Monteiro Sasha , Neves Teresa
Published: June 2023

Background: Medical students face a unique collection of stressors, both intrinsic and external with consequences to health and well-being, ultimately impacting patient care. Health education institutions play a role in perpetuating or mitigating this experience of stress.
Objective: This pilot project aimed to identify the impact of an extra-curricular wellness program on well-being among naturopathic medical students.
Methods: Participants engaged in a 2-day facilitated wellness retreat followed by three monthly workshops, which coincided with the onset of the COVID-19 pandemic. Frequencies of pre-defined behaviours, and validated measures of stress, resilience, and mental health were assessed prior to the start of the program, immediately upon completion, and 6 months after the program concluded and were compared with wait-listed controls.
Results: There was a clear trend toward reduced stress perception and anxiety, along with improved resilience among program participants through the duration of the study and compared with controls. The positive trends over the course of the study, especially during a global pandemic, suggests that the intervention was beneficial to participants.
Conclusion: The results suggest that supporting students in cultivating the skills of resilient coping may reduce perceived stress and improve mental health for medical students, even during times of uncontrollable external stress.
Breast Cancer in Elderly Females
Authors: Abasher Mona Mahmoud , Sidahmed Amal Abdelhakam , Abdelmoniem Asjad , Ahmed Hyffa Osman Mohamed
Published: June 2023

Breast cancer develops when the breast’s cells multiply uncontrollably. Breast cancer ranks as the second leading cause of cancer-related mortality among women. Breast cancer risk increases with age. Almost 1 in 7 women will experience the onset of breast cancer during their lifetime. Breast cancer is a malignant or cancerous tumour that develops from cells in breast tissue. Although they are non-life-threatening and confined to the breast, some women develop benevolent or non-cancerous breast lumps. Many people are unaware they have breast cancer since the early stages of the disease are frequently benign. Early discovery provides more time for evaluation and treatment, which can help prevent negative effects. Self-examination and several diagnostic tools as mammography, ultrasound, and nuclear medicine, are used to evaluate invasive and non-invasive breast cancer. Several therapies associated with breast cancer treatments include chemotherapy, radiation therapy, hormone therapy, and bone-directed therapy. Surgeries can also effectively treat breast cancer, such as lumpectomy and mastectomy. This suggests that effective therapies are progressing. This review aims to determine breast cancer’s causes, prevalence, and treatments in elderly women. The authors have discussed the disease’s treatment criteria and protocols, such as pharmacological therapies, herbal treatment, lifestyle modifications, and physical activities

NOVAS PROCURAS DO CONSUMIDOR E O CONTEXTO CULTURAL
Authors: Brito Lélis Maia , Da Silveira Lidiane Nunes
Published: June 2023

As tendências de consumo emergem uma nova dinâmica em relação às definições de qualidade dos alimentos quanto as relações entre produtor e consumidor e entre o contexto rural e o urbano. Isso se dá pelo fato de que o consumo não pode ser compreendido somente pela lógica econômica, mas pelos sentidos e significados sociais e políticos compartilhados através dos bens de consumo. É com esse sentido cultural, tradicional e repleto de significados que o queijo minas artesanal é apresentado neste trabalho como uma exemplificação das “novas procuras” dos consumidores. A valorização do queijo minas artesanal envolve, de um lado, o fortalecimento da legislação que visa preservar os atributos imateriais da produção e, de outro lado, o comportamento do consumidor, o qual, cada vez mais, tem procurado por novos valores sobre esse tipo de produto no mercado. O objetivo deste trabalho é discutir sobre as "novas procuras" do consumidor e relacioná-las com o contexto cultural da produção e comercialização do queijo minas artesanal. Este trabalho propôs explicar que há um relacionamento entre o consumo de queijo minas artesanal e os valores culturais envolvidos no comportamento do consumidor.  Isso permite inserir na discussão que o simbolismo e a cultura do queijo artesanal mineiro possuem afinidades com os valores cultuados por segmentos de consumidores no âmbito da cultura de consumo.
The Influence of Belly Dance on the Second Stage of Labor and the Condition of the Baby
Authors: Herlyssa
Published: June 2023

One alternative to exercise during pregnancy is to participate in belly dance, which is fun and will increase the confidence of pregnant women. This study aimed to determine the effect of belly dance on the duration of the second stage of labor and the condition of the newborn. The research design is quasi-experimental. The intervention group consisted of pregnant women participating in belly dance at least 4 times. At the same time, the control group is pregnant women who do not participate in belly dance. The sampling technique was quota sampling. The samples of pregnant women with a gestational age of 26 weeks were 30 pregnant women in the intervention group and 30 pregnant women in the control group. The study was conducted at the Kebon Jeruk and Palmerah Health Centers in March – December 2017. The results showed that the characteristics of respondents in the intervention and control groups were almost the same, namely age at risk, high education, not working, and multipara. There was a significant difference in the second stage of labor duration after the Belly dance was performed in the intervention group. There was no significant difference in the baby's weight at birth after the Belly dance was performed in both the intervention and control groups. In addition to belly dance, parity also influences belly dance on the duration of the second stage of labor. It is recommended that the Kebon Jeruk sub-district health center introduce belly dance movements to pregnant women as a variation in pregnancy exercise activities

Published: June 2023

Nascimento pré-termo é aquele que ocorre com menos de 37 semanas de idade gestacional. Considera-se com baixo peso o bebê que nasce com menos de 2.500 gramas. Ambos são fatores de risco para o desenvolvimento de afecções perinatais. Embora existam estigmas envolvidos no nascimento de um bebê com essas condições – tais como falta de informações dos familiares –, o Método Canguru, como parte da educação em saúde, pode contribuir para mitigar mortalidades nesses recém-nascidos. Tais estratégias educativas podem ser realizadas pela utilização de tecnologias educacionais, como infográficos animados norteados por roteiros. O presente estudo objetivou a concepção e a execução da elaboração do conteúdo (roteiro) para o desenvolvimento de infográfico animado sobre o Método Canguru. Trata-se de um estudo metodológico. No roteiro, após análise documental e de similares (vídeos semelhantes na rede), delimitou-se o tema Método Canguru, com descrição de suas etapas e vantagens, focado em famílias de recém-nascidos pré-termo e/ou com baixo peso, hospitalizados em Unidades de Terapia Intensiva. Articulou-se a criação da identidade dos personagens com a locução e auxílios visuais, possibilitando explorar diferentes formas de aprendizagens e melhorar a capacidade de recepção das informações. Totalizaram-se 22 cenas que abordam a apresentação das personagens e dos conceitos, a descrição de etapas, as atribuições do enfermeiro neste contexto, as vantagens da realização da posição canguru e a importância do acompanhamento do bebê e da família pela Atenção Primária à Saúde. Apesar da complexidade que envolve a elaboração de recursos educacionais, foi possível construir um roteiro para o desenvolvimento do infográfico animado sobre o Método Canguru com informações que buscam atender às necessidades do público-alvo. Espera-se que este estudo possa fomentar e ampliar a prática da utilização de recursos educacionais para o cuidado qualificado do recém-nascido pré-termo e promover a reflexão de profissionais da saúde-gestores-comunidade sobre o tema.
Improvement of the Accuracy of SSVEP-BCI with In-Ear EEG Using Multiple Regression Analysis
Authors: Kondo Sodai , Tanaka Hisaya
Published: June 2023

A brain-computer interface (BCI) is an interface that reads brain activity and operates a computer. Typically, BCI involves wearing a device on the head to measure brain waves. EEG meters are cumbersome for the user when worn and require individuality techniques to reduce impedance. In-Ear EEG, which is obtained from electrodes placed near the inner and outer ear, is expected to solve these problems. Users can use it to have a comfortable BCI experience. However, in-Ear EEG has the problem that the EEG used for BCI uses EEG located far from the actively observable areas of the brain, which results in poor signal quality. Steady state visual evoked potential (SSVEP) is an EEG that is predominantly observed in the primary visual cortex in the occipital region during gazing at a flashing stimulus, and SSVEP-BCI is expected to be used as a new communication tool. Ear EEG will greatly advance the social implementation of SSVEP-BCI. In this study, electrodes were placed at 10 locations near the ear and 4 locations on the back of the head. SSVEP-BCI with 28 different inputs including alphabets was designed and evaluated. The accuracy of the SSVEP-BCI with signals obtained from the occipital region was 84.92%, and that of the BCI with signals obtained from the ear was 28.17%. Using the occipital and intra-ear EEG data sets as the teacher data, multiple regression analysis was performed to improve the accuracy, and an accuracy of 55.83% was achieved. These results indicate that improvements are needed to make in-Ear EEG based SSVEP-BCI practical. It also suggests that a communication tool using in-Ear EEG based SSVEP-BCI may be feasible in the future.
User Expectations of Facial Recognition in Schools and Universities: Mixed Methods Analysis
Authors: Roundtree Aimee
Published: June 2023

This project explores the relationship between community perception, expectations, and experiences with privacy risk and facial recognition technology used in schools and universities. The methodology includes a meta-analysis of current literature and content analysis of social media content on the subject matter. The meta-analysis revealed that positive attitudes about facial recognition technology used in schools only reflect a portion of the total surveyed. A sentiment analysis of tweets about facial recognition technology used in schools and universities revealed that concerns skyrocketed in 2020, probably caused by the pandemic forcing courses and academic activity online, thereby heightening awareness about facial recognition technology and its implications. Tweets expressed concern about privacy, ethics, and data management. Negative emotion spiked in discussions about unrest and conflicts, possibly due to news about facial recognition used in crowd control. Concerns about power differentials spiked in conversations about how facial recognition would affect academics and education. The trends in attitudes directly pertain to current and projected problems and negative implications of facial recognition on vulnerable populations, including children, seniors, ethnic minorities, and transgender populations. The heterogeneity of the U.S. market requires sensitivity to issues of diversity, equity, and inclusion. Recommendations include operationalizing lessons learned from user experience research. Future studies should investigate trade-offs between privacy, safety, and autonomy.

Aerodynamics plays a crucial role while designing any automobile components. Due to the aerodynamics the entire performance of the automotive will be changed. With an improvement in computer technology, manufacturers are looking toward computational fluid dynamics instead of wind tunnel testing to reduce the testing time and cost. In this paper a car model considered and it is modeled using solid works modeling software. The car material is stainless steel. The lift and drag of production vehicle are determined by the analysis of flow of air around it using Ansys. The aerodynamic analysis of the design parameter of car will be performed by using a suitable turbulence model and to compare the drag coefficient of design of car model by using CFD software result and experimentally result and the results will be validated by CFD analysis/experimental studies. The result of software analysis has agreed excellently with field experimentally results. The aerodynamic and crash analysis on car with of material Al 6061&AISI 4130 with wall and vehicle is considered The given model is tested under frontal collision conditions and the resultant deformation and stresses are determined with respect to a time of 80 Mille sec for ramp loading using ANSYS software. The crash analysis simulation and results can be used to assess both the crashworthiness of current frame and to investigate ways to improve the design. This type of simulation is an integral part of the designcycle and can reduce the need for costly destructive testing program.
News Life Cycle and the Hybrid Media System
Authors: Serrano Tellería Ana
Published: June 2023

Following a brief examination of recent theories, this proposal describes the transmedia ideals, logic and values for journalism and explores how transmedia storytelling addresses the need to ensure the continued relevance of journalism. We test the ideals, logic and values and refine the evolving features and strategies employed by Spanish legacy media through case study analysis. Thus, this research analyses and describes the use of languages, genres and formats; strategies, resources and platforms for the creation, collaboration and distribution (News Lifecycle, Serrano-Tellería, Jin and Arroyo, 2019) of journalistic products about Covid-19, and determines whether a transmedia logic is being followed. Likewise, this study proposes a set of good practices that can be applied to other stories- products and media in everyday and planned routines. For this, the field work focuses on the analysis of two aspects: the interface design and the creation and dissemination of content. The pandemic represented a unique frame of analysis due to the intrinsic work conditions, routines and dynamics as well as its limitations and increased demands for information. Thus, we concluded that transmedia core values, ideals and logic offer a suitable framework to embrace in everyday media work and specifically, in journalism, to adapt, innovate and overcome its crisis and challenges, opportunities and potentials. Transmedia means an ideal, a logic, a group of values to bear in mind when constructing a story. To adapt storytelling to media production, bearing in mind all possible genres, languages, formats, semiotics and strategies is a fundamental step because audiences are used to consuming media on different devices and want the best of all of them to have a full experience.

Published: June 2023

Digital media have become an integral part of the journalism industry and of audience habits – in 2021 our research registered 2873 active news websites in Spain. First, this paper explores trends facing online news; it sets out the criteria used to identify a news brand as digital-native or non-native; and it presents the results of our classification. This includes: data on the presence of news titles both on proprietary platforms (print, radio, TV or app) in addition to their websites, and on external platforms (Facebook, Twitter, Instagram, YouTube and Telegram); their geographic scope (hyperlocal, local/regional or national/global); their subject (general or specialized coverage); and on ownership and language used. Almost 70% of the media were regional or local, while 60% covered general news, and one in three were linked to a print product, almost as many as those with their own app for users. Social media uptake is so widespread that more than 95% of the sites are on Facebook, with a similar number on Twitter, while more than 60% can be found on YouTube, and similarly on Instagram. Among specialized sites, sport is the largest category, comprising twice as many digital-native sites (106) than sites with traditional roots (46). The entertainment focus expands in the digital environment, and online-originated culture, business and science and technology outlets also outnumber legacy publications.
Digital-native news media: Reach in 46 countries, top brands and user profiles in Spain
Authors: Kaufmann-Argueta Jürg , Negredo Samuel
Published: June 2023

Digital-pure news publications have become competitive players in many countries, populating audience rankings in the context of a high-choice media environment. With the aim of gaining insight into the performance of digital-native news brands around the world and into how their audiences are similar or different to those of media with traditional roots in Spain, we draw on survey data for 2021 and 2022, respectively. First, we examine what proportion of online adults use any of the most popular digital-pure news brands in 24 mostly European countries and in 22 markets in America, Africa and the Asia-Pacific region, and we highlight how the main digital-native brands rank among online news sources, based on their weekly audience reach. Then we compare the user profiles of the five most-used online-only news organizations in Spain, against the audiences of the top five legacy brands (N = 2028), looking at reader loyalty, gender, age, income and education levels, and political leaning. With this media-centric approach to audiences, we find that digital-native news media brands either lead (in 15 out of 46 countries) or occupy some of the top positions by weekly reach in most markets, with Nordic countries standing out as an exception. In Spain, audiences of the top digital-native brands check them slightly less frequently than the users of news sites with traditional roots. News sites in our study are slightly more popular among males, older people, and more affluent and formally educated users who can define their political stance. Nevertheless, the diversity of editorial approaches found among sites in an externally pluralistic news media market inevitably results in brands with user profiles that show exceptions to these trends.
WhatsAppening to the news in Brazil? A mixed-method study on news publishers’ struggle to adapt to WhatsApp’s inherent characteristics of mobile and interpersonal communication
Authors: Carpes Giuliander , Moreu Enric
Published: June 2023

After Facebook started prioritizing posts from family and friends on its newsfeed at the beginning of 2018, news consumption on social media increasingly migrated to other mobile applications such as WhatsApp. This has put pressure on media organizations to establish channels on the platform in an attempt to compensate for the decline in audience figures. Journalistic practices on WhatsApp remain poorly understood. Building on the “diffusion of innovations” theory, this article examines whether the way newsrooms have adapted to WhatsApp follows similar patterns to their adoption of social media for news distribution, or whether they have been able to develop new practices that fully consider the tool’s inherent characteristics of mobile and interpersonal communication. Focusing on Brazil as a case study, this study draws on the analysis of 8,855 messages sent to WhatsApp news channels and interviews with 21 editors and executives from publishers, and shows that newsrooms have hardly adapted to the possibilities of WhatsApp beyond its technological aspects. Audience engagement has often been neglected or has been addressed with a lack of consistency. According to the interviewees, constraints presented by WhatsApp, such as the large amount of manual work it requires of newsrooms, make it difficult for news organizations to adopt the platform to transform their relationship with their readers.

Iron oxide scale generally forms on low-carbon steel surfaces during the hot rolling processes andproduces as solid waste more than 100 thousand tons per year. The utilization of the iron oxide scaleis one possible way to reduce the production cost for steel plants and promote environmental protection. Acrylonitrile-Butadiene-Styrol-Copolymer (ABS) is widely used as engineering plastic for automotive parts because of its high strength and wear resistance. The recycling of iron oxide waste as reinforcement particles for enhancing the tensile strength of ABS composite was studied. The iron oxides were recycled by carbon powder at a high temperature between 1150℃ to 1350℃ up to 120 min. After the reduction process, the reduced iron from an optimal condition with the iron-rich fraction was ground to powder. Afterward, the 0.3 vol% to 1.3 vol% powders were mixed with ABS polymer powder and formed as composite filaments for additive manufacturing (FDM 3D printing). The tensile strength of pure ABS filament increased to 37.16 ± 2.37 MPa when added recycled iron powders. The regular distribution and 13.68 ± 9.78 µm of recycled-iron particle sizes on the ABS matrix were investigated and correlated to the mechanical properties.

Published: June 2023

Sensitive measurements require a vibration isolation system to safeguard against detrimental tremble. Two types of vibration isolation systems - passive and active - are currently implemented. The spring-based passive designs usually accompany with ineffective low-frequency response. Therefore, the active designs, consisting of sensors, feedback control systems, and actuators, are consolidated to improve the total effectiveness of the cancellation performance. In this work, we focus on developing the actuator founded on electromagnetic spring to be incorporated into our compact quantum gravimeter. Each spring-actuated part comprises two repelling Nd magnets positioned face to face inside a solenoid. With this configuration, the spring can also work in the passive mode via repulsive magnetic force. In the active mode, the exerted force is a result of magnetic fields formed by the magnets and the current-controlled solenoid coils. By changing the coil current, the stiffness of the spring can be modified, and thus the displacement can be controlled.  Different sizes of magnets are explored, and their force behaviors in passive and active modes are characterized. The implementation scheme of the actuator in the quantum gravimeter is also discussed.

The objectives of this study were to test the strain Wickerhamomyces anomalus WO2 as a plant growth-promoting yeast (PGPY), to evaluate the effect of its inoculation on the growth and physiological performance of Suaeda fruticosa subjected to salt stress, and to understand by which mechanism the yeast can protect the plant from high salinity. The results showed that the strain is halophilic, and grows at salt concentrations of up to 15%. Salinity caused decreases in chlorophyll a, b, and T in both inoculated and non-inoculated S. fruticosa. A significant increase in carotenoids was observed in W. anomalus WO2 inoculated plants. Inoculation enhanced the production of proteins, polyphenols and flavonoids at 1% of salinity, and sugars at all concentrations of NaCl. Although Na+ and K+ were higher in the leaves of non-inoculated plants compared to inoculated ones, the correlation of sodium translocation factor (TF) with salinity was very strong positive only in the inoculated plants. The production of carotenoids had a very strong positive relationship with salinity in inoculated plants, and a very strong negative correlation in non-inoculated plants. Soluble sugars were very strongly positively correlated with salinity in both inoculated and non-inoculated plants. However, a strong positive correlation of sugars with carotenoids was observed only in inoculated plants. This strain proved to be a promising candidate as a PGPY under salt stress. This work amends the PGPY bank with new strains having interesting abilities to resist high concentrations of NaCl and which can be used in the future as a biofertilizer.

The use and consumption of wood has always captured the attention of forest researchers, mainly from the point of view of forest management and the sustainable processing of raw materials. For this reason, the wood industry has not only been concerned with the maintenance of forests, but also with efficient processing. The objective was to identify, analyse and discuss the main elements that influence the efficient use of natural timber resources at a global, regional and local level, providing a historical and current perspective of the industrial forestry sector in Mexico. Historically, the wood industries worldwide have been concerned with applying intensive silvicultural treatments in native and artificial forest stands, in search of satisfying the demand of a growing market. In this context, industries evolved as processes needed to be more efficient. Therefore, efforts were made to reduce and take advantage of forest residues, at the same time various historical events generated additional needs. At present, the integration of silviculture and forest transformation allow to increase and improve the quality of the products generated. Through the application of intensive silvicultural treatments, products of a single species are obtained. However, it is possible to direct production to a specific market as the forest mass develops. For its part, selective treatments in uneven-aged forests maintain a constant production of diverse products for different specialized markets. In Mexico, it is imperative to analyse and generate innovative or competitive products derived from wood to improve the efficiency of forest harvesting.

Published: June 2023

Moringa oleifera Lam. leaves are commonly used for diabetes worldwide. To date, there has been no research study done to investigate its effect on lipid and carbohydrate profile in Algerian diabetic patients. This pilot clinical study aimed to evaluate its long term-effect on lipid and carbohydrate profile in Algerian diabetic patients in preparation for a larger trial. 44 diabetic patients from Adrar city were administrated with 3600 mg of MO leaves powder twice a day at breakfast and at 7 p.m. for a period of 90 consecutive days, along with their regular hypoglycemic medications, in order to evaluate their serum lipid (TC, C-HDL, C-LDL and TG) and carbohydrate profile (blood sugar and HBA1c), weight, BMI and blood pressure, across five time-points (on days 0, 3, 7, 30, and 90). The results showed that oral administration of Moringa oleifera powder had a statistically significant effect on blood sugar (HBA1c), LDL-C, HDL-C levels in diabetic patients (p<0.05). Moringa oleifera leaf powder seemed reduced LDL-C, and HBA1c and elevated HDL-C, in diabetic patients. No side effect was reported by any participant. However, it did not have a statistically significant effect on weight, BMI and blood pressure. The data from the present clinical trial provide persuasive, although preliminary evidence supporting the therapeutic potential of Moringa oleifera leaf powder for managing chronic hyperglycemia and dyslipidemia in Algerian patients with diabetes. A more extensive trial is necessary to determine the Moringa oleifera leaf powder optimal dose and evaluate if its effect results into long-term advantages. In addition, further investigations are required to clear the underlying mechanisms involved with these effects.

The objective was to evaluate and compare the precision of estimation of dasometric variables, survey times and costs of two sampling methods versus a census, applied to a natural even-age mass of Pinus arizonica Engelm. in the municipality of Guachochi, Chihuahua, Mexico. Nine fixed-dimension and nine variable-dimension sites were performed with Bitterlich's angular sampling at coincident sample points. Times from start to finish were taken by site and technicians from the State were surveyed to determine sampling costs. ANOVA tests were developed at a significance level of 0.05, comparing both methods with the census. The results indicate that, in both samplings, the number of trees per hectare does not present statistical differences with respect to the census. The basal area by both methods was not statistically different, however, fixed dimensions present an error greater than 5%. Finally, the volume per hectare estimated was similar to that of the census, according to the rates carried out, greater precision was found by the variable area method (error=0.03%). The execution time showed significant differences (p=0.0001), the fixed dimension site required a mean time of 44 minutes and the variable dimension one 10 minutes 26 seconds. The total costs are 679.90 and 654.33 Euro to sample nine fixed-dimension and nine variable-dimension sites respectively, showing significant differences (p=0.0008). It is concluded that both methods are statistically acceptable for the variables evaluated in the type of forest mass studied.

Haloxylon ammodendron (C.A.Mey) Bunge is one of the important species of arid desert vegetation in China, and it is also an ideal material for studying plant stress resistance, which plays an extremely important role in protecting desert ecosystems and preventing land desertification. However, there are relatively few studies on the regeneration of the fusiform, and the genetic transformation system has not been successfully reported, which restricts the in-depth study of the molecular mechanism of shuttle propagation and stress resistance. In the present study, the seeds, hypocotyls, cotyledons, cotyledon nodes, terminal buds and fixed buds were used as explants, and a set of tissue culture and plant regeneration system was established by inducing adventitious buds, adventitious bud rooting and transplanting. The results showed that amongst different H. ammodendron explants, i.e., seeds, hypocotyls, cotyledons and cotyledon nodes, the last induced budding effect was better. The optimal medium for inducing clandine buds by cotyledon segment differentiation is 0.5 mg·L-1 NAA+0.5 mg·L-1 6-BA induced budding rate was high, reaching 61.90%, rooting medium was 1/2 MS+1 mg·L-1 NAA +1 mg·L-1 IBA + 1 mg·L-1 IAA with a rooting rate of 50%. The results of this study will provide a theoretical basis for the genetic transformation of H. ammodendron.
O uso das tecnologias digitais da informação e comunicação no âmbito escolar: possibilidades para uma Práxis docente

Published: June 2023

O presente artigo tem como finalidade iniciar uma discussão acerca da possibilidade de (res)significação das práticas docentes em uma perspectiva de práxis, considerando o uso das tecnologias digitais da informação e comunicação no ambiente estudantil. A utilização de conhecidas tecnologias digitais do grande público, tais como, smartphones, computadores, tablets e notebooks, em sala de aula, vem ocupando, cada vez mais, espaços nas atividades escolares. Nesse viés, a pandemia de Covid-19 oportunizou a intensificação do uso de tais recursos digitais para o cumprimento da grade curricular dos estabelecimentos educacionais. Assim sendo, este estudo se pautará em uma pesquisa qualitativa, básica, bibliográfica, do tipo descritivo-exploratória e traz como pergunta reflexiva: de que modo o uso das tecnologias digitais da informação e comunicação poderá contribuir, didaticamente, para a (res)significação do processo de ensino e de aprendizagem do discente, considerando uma práxis transformadora na educação? Portanto, buscar-se-á amparar a referida pesquisa nas obras de autores como Libâneo (1990); Rojo (2009); Vázquez (2007); Franco (2012); Coscarelli (2016) e Saviani (2019). Com isso, pretende-se intensificar o exame dos conceitos e bases epistemológicas que se assentam nos estudos desses autores e de outros que, eventualmente, poderão ser trazidos à tona para compor o diálogo em torno da práxis docente no universo escolar.

Este trabalho propõe a elaboração de um aplicativo bilíngue (Português-Libras) para o ensino de pessoas surdas, que apresenta em Português e em Língua Brasileira de Sinais: termos específicos, conceitos, uma breve contextualização dos conceitos, textos da disciplina e ementa a partir da proposta da docente. O app foi elaborado a partir dos conteúdos da disciplina Processos Linguísticos, disciplina fundamental do curso de Letras Libras, curso ofertado pela Universidade do Estado do Pará (UEPA) e pode ser utilizado em qualquer área do conhecimento para apresentar termos específicos para alunos surdos. Esta pesquisa justifica-se pelo reconhecimento de uma necessidade apresentada pela comunidade surda ao ingressar no ensino superior, pois enfrenta dificuldade na compreensão de termos específicos de determinada área, constatou-se tais barreiras linguísticas por dados bibliográficos e experiências na UEPA ao identificar vivências visuais e linguísticas peculiares dos graduandos surdos. Portanto, busca-se criar estratégias de apoio aos docentes a fim de adaptar conteúdos complexos e dinamizar os conteúdos para formas visuais. No intuito de minimizar as dificuldades enfrentadas pelos graduandos surdos, partiu-se do seguinte problema: Como conceber e desenvolver um aplicativo bilíngue (Português-Libras) para docentes que atuam com graduandos surdos, do curso de Licenciatura Plena em Letras Libras da UEPA, buscando potencializar a aprendizagem dos termos específicos da disciplina Processos Linguísticos? O objetivo geral deste trabalho é conceber e desenvolver um aplicativo bilíngue (Português-Libras) para buscar potencializar a aprendizagem dos termos específicos da disciplina Processos Linguísticos. Como resultado da pesquisa constatou-se as dificuldades enfrentadas por graduandos surdos, no que se refere à compreensão de termos e conceitos específicos dentro de determinadas áreas do conhecimento, o aumento significativo de ingresso de pessoas surdas no ensino superior e os benefícios do uso de recursos tecnológicos, tais como aplicativos, na educação de surdos.

Published: June 2023

In December 2019, the new coronavirus that was named SARS-CoV-2 was identified in China. The virus spreaded quickly and in March of 2020 it was declared a pandemic by the World Health Organization. Due to the initial lack of rapid diagnoses and effective treatments, the health systems were overloaded as a consequence of the high number of infected and severe cases. The diagnostic techniques currently available have limitations, for this reason, the search for new methods with sensitive, fast, cheap and locally used techniques, such as electrochemical biosensors, has been widely explored. Given the advantages of developing electrochemical biosensors for sensitive and selective diagnosis, this systematic review aimed to search for publications on the subject and answer the following question: The diagnosis of COVID-19 performed through an electrochemical biosensor, in individuals with suspected disease is it as efficient as that performed by RT-PCR? A study protocol was developed following the PRISMA-DTA guidelines and registered with PROSPERO under the approval code CRD42021282561. Searches were carried out in six electronic databases, inclusion and exclusion criteria were applied and seventeen publications were selected for this review.  Based on the data, the analyse of risk was done using QUADAS-2. The results were presented in a descriptive qualitative manner it was not possible to carry out a meta-analysis.
