Domînio de textos multimodais na era tecnológica para formação de sujeitos críticos
Authors: Lopes Elma dos Santos
Published: July 2023

O presente trabalho tem como objetivo discutir a pertinência da inserção dos textos multimodais nas aulas de Língua Portuguesa. Da mesma forma, propõe a discussão acerca da importância dessas novas construções linguísticas no desenvolvimento de habilidades e competências para a formação da criticidade frente às novas comunicações, tão necessárias para a formação cidadã dos estudantes. Percebe-se que os textos contemporâneos são dinâmicos, valendo-se de diversos signos linguísticos para sua significação nas práticas sociais vigentes. Ademais, é sabido que a geração e a era atual se caracterizam pela utilização frequente das Tecnologias Digitais da Informação e Comunicação (TDICs), e requerem desses, domínio consciente das plataformas para sua atuação ativa, libertadora e transformadora em sociedade. Além desses fatos, o estudo faz uma reflexão sobre a disseminação de informações veiculadas nos dispositivos digitais e suas consequências manipulatórias no pensamento coletivo. Para tanto, sugere-se meios educacionais e didáticos de ensino-aprendizagem, como a curadoria, que visam estimular os discentes a criarem o hábito de filtrar e selecionar as informações às quais são diariamente bombardeados, assim como verificar a autenticidade e a veracidade de conteúdos digitais, minimizando os impactos das Fake News no cotidiano. Para tal, foram realizadas pesquisas bibliográficas sobre multiletramento e textos multimodais, com especialistas e documentos renomados, à luz das inovações teóricas da autora Rojo (2012; 2015). No que concerne à analise ideológica do discurso, foram analisados os estudos de Orlandi (2009); enquanto a reformulação dos currículos de ensino ficou a cargo das orientações provenientes da Base Nacional Comum Curricular (2017) do Ensino Médio. A partir desse estudo chegou-se à conclusão de que, seguindo os currículos reformulados, a escola precisa implementarnovas metodologias de escrita, leitura e análise de textos em consonância com o contexto vigente, proporcionando aos educandos o discernimento necessário para melhor compreender e incidir no mundo contemporâneo.
A influência da tecnologiana educação de jovens e adultos: uma abordagem desde a alfabetização a uma proposta de atividade de Língua Portuguesa no Ensino Fundamental II
Authors: Santos Anaceli Aparecida Fonseca , Lima Emerson dos Santos , César Rozevania Valadares de Meneses
Published: July 2023

Com o avanço da tecnologia e a grande facilidade ao seu acesso, é imprescindível que a educação esteja inserida nessa modernidade, inclusive a Educação de Jovens e Adultos (EJA), pois aprender, utilizando-se dos recursos tecnológicos que contribuem para esse processo, torna o aprendizado mais coeso e mais relevante para o aluno adulto, uma vez que sai dos limites do antigo “be-a-bá”, ao qual, muitas vezes, ele estava acostumado a ver na escola, quando estavam na idade escolar. Talvez, por isso, tenha desistido dos estudos na época. Este trabalho é o resultado de uma proposta de atividade de língua portuguesa com o uso das tecnologias aplicadas com alunos da EJA, durante um projeto de reforço, realizado em uma Escola do Município de Itapicuru/BA, e tem o objetivo de otimizar o processo de leitura e escrita de alunos da EJA com o auxílio das tecnologias da informação e comunicação. Para isso, baseia-se no estudo do caso supracitado, valendo-se de uma pesquisa qualitativa de cunho bibliográfico, e fundamenta-se em Freire (1989), Ferreiro (1983), Belloni (2009) e Trindade e Nunes (2018). Para coleta de dados, foram aplicados questionários aos docentes e entrevista com grupo focal aos alunos, além da observação. Foi possível concluir que os recursos utilizados como software educativo, emoticons, slides e áudio, foram importantes instrumentos de mediação no processo de aprendizagem dos alunos, visto que houve um avanço nos níveis de escrita desses discentes, além disso, também se percebeu que os alunos partícipes do projeto não se evadiram, o que leva a crer que o uso dessa ferramenta também contribui para a permanência do estudante na escola.
Unravelling ceremonial calf burials among Asian elephants in Northeast India
Authors: Kaswan Parveen , Roy Akashdeep
Published: July 2023

Rampant environmental change and forest destruction push elephants, both
Asian and African, to explore human spaces to fulfil their dietary and
ecological requirements. Many ‘novel’ elephant behaviour in sharing
spaces come to the limelight. Elephant calf burial is reported in
African literature but remains absent from the Asian context. We
concretely report calf burials by Asian elephants in the eastern
Himalayan floodplains of the north Bengal landscape. The study area
consists of fragmented forests, tea gardens, agricultural lands, and
defence establishments, among others. Tea gardens form the majority of
elephant corridors, and we explain the burial strategy of elephants in
the trenches of tea gardens. We present four case reports of calf
burials by elephants. We aimed to understand the perimortem strategy and
postmortem behaviour of Asian elephants. The major findings reflect that
the carcasses were carried through trunks and legs for a distance before
burying in a ‘legs-upright-position’. We further investigated the
underlying reason for calf deaths through postmortem examinations.
Direct human intervention was not recorded in any of the four deaths.
Through opportunistic observation, digital photography and fieldnotes,
and postmortem examination report, we suggest that the carcasses were
buried in an abnormal recumbent style irrespective of the reason for
calf deaths. Through long-term observation, we further report that the
elephants in this region clearly avoid the paths where carcasses were
buried, attributing to “bad milestones” and “bad omens”. We discuss
and connect the literature of two distinct elephant species and also
compared thanatological studies of other sentient nonhuman species.
Keywords: Thanatology, animal behaviour, Asian elephant, calf burial,
eastern Himalayas, tea gardens
A Theoretical Framework of COTS Components Space Application Based on “Risk Information Entropy”
Authors: Wen Zhang , Dang Wei , Liang Ao , Yewei Feng
Published: July 2023

Commercial off-the-shelf (COTS) components have been widely used
in the aerospace at home and abroad, but there is no systematic theory
of quantitative evaluation of the risk. Therefore, based on Shannon’s
information entropy, the risk information entropy is proposed to
describe the risk uncertainty of COTS components in space application.
And a theoretical framework of COTS components space application is
established, which includes calculation and decrease of the entropy.
According to whether the failure mode and failure frequency ratio are
known, different risk information entropy models are established for
components. Based on this, a system risk information entropy model is
established, and a continuous optimization method for the risk
information entropy model is proposed. In addition, it introduces how to
achieve system entropy reduction from several aspects, such as selection
guidance, application certification, reliability reinforcement, and
status detection.
Partly Cloudy with a Chance of Mosquitoes: Developing a macroecological approach to forecasting mosquito populations and phenology under changing climates

Published: July 2023

Climate-induced shifts in mosquito phenology and population structure
has important implications for the health of humans and wildlife. The
timing and intensity of mosquito interactions with infected and
susceptible hosts is a primary determinant of vector-borne disease. Like
most ectotherms, rates of mosquito development are expected to change
under warming climates. However, developing accurate predictions of
mosquito phenology under climate change that can be used to inform
management programs remains challenging despite an abundance of
available data from long-term monitoring programs. Climate change may
have variable effects on mosquito demography depending on the traits of
individual species. Here, we review a suite of modeling approaches that
could be applied to generate forecasts of mosquito activity under
climate change and evaluate the strengths and weaknesses of different
approaches. We argue that four primary life-history and physiological
traits can be used to constrain models, and demonstrate how this prior
information can be harnessed to develop forecasts of mosquito activity
under changing climates.
The Maturation Of Geothermics As A Discipline And Some Unresolved Problems
Authors: Back A. E.
Published: July 2023

Some of the difficulties involved in the determination of heat flow density values (HFD) and of the associated statistical estimate of their errors are reviewed. Particular attention is paid to the problems that arise when a local HFD, which may have narrow error bounds, is mistakenly accepted as a regional HFD, which may have significantly larger error bounds, and used to downward continue the temperature and heat flow field to lithospheric depths. Two aspects which are covered in some detail are the errors in determining equilibrium temperature gradients in boreholes or lake and oceanic sediments, and the errors which arise in thermal conductivity measurements when the thermal contact resistance, especially for porous rocks saturated with a low conductivity fluid, is mistakenly assumed to be negligible.Algumas das dificuldades envolvidas na determinação dos fatores de densidade de fluxo térmico (HFD) e das estimativas estatísticas de seus erros são revisadas. Uma atenção particular é dada ao problema que aparece quando um HFD local, que pode ter erro pequeno, é erroneamente aceito como um HFD regional, que pode ter erro significantemente maior, e é usado para continuar o campo de temperatura e de fluxo de calor a profundidades litosféricas. Dois aspectos que são discutidos em detalhe são os erros na determinação dos gradientes de temperatura em equilíbrio em furos e sedimentos lacustres ou marinhos e os erros que aparecem nas medidas de condutividade térmica quando a resistência térmica de contato, especialmente para rochas porosas saturadas com um fluido com baixa condutividade é erroneamente suposto como desprezível.
Laboratory Thermal Conductivities Applied to Crustal Conditions
Authors: Buntebarth G. , Rueff P.
Published: July 2023

Using a divided bar apparatus, the thermal conductivity of some sedimentary and some common crystalline rock samples has been investigated. The divided bar can be heated by a guard heating system up to 600°C, and a contact pressure of about 50 MPa can be applied. The sandstones (Upper Carboniferous) exhibit a remarkable nonlinear increase of the thermal conductivity with pressure up to about 10 MPa. Siltstones and the crystalline rocks demonstrate a linear pressure dependence of the conductivity within the applied pressure range. The dependence of the conductivity upon temperature is high for sandstones and quartz-bearing rocks. The most fine grained siltstone and some crystalline rocks show a weak temperature sensitivity of the conductivity. If the thermal conductivity of sedimentary rocks is applied for heat flow determination, a difference of up to 20% may arise when the variation of conductivity with pressure and temperature is applied or neglected. Applying the measured thermal conductivity of crystalline rocks, the thermal conductivity vs. depth is estimated for Precambrian and Phanerozoic areas. Utilizando-se de um dispositivo de barra dividida, estudou-se a condutividade térmica de amostras de algumas rochas sedimentares e de algumas rochas cristalinas comuns. A barra dividida pode ser aquecida por uma manta de aquecimento até 600°C, e uma pressão de contato da ordem de 50 MPa pode ser aplicada. Os arenitos (Carbonífero Superior) apresentam um notável crescimento não-linear da condutividade térmica como função da pressão até aproximadamente 10 MPa. Siltitos e rochas cristalinas apresentam uma dependência linear da condutividade com a pressão dentro do intervalo de pressões aplicadas. A dependência da condutividade térmica com a temperatura é alta para os arenitos e para as rochas contendo quartzo. A maioria dos siltitos e algumas rochas cristalinas mostram que a condutividade é pouco sensível à temperatura. Quando a condutividade térmica de rochas sedimentares é utilizada em determinação de fluxo térmico, diferenças de até 20% podem ocorrer se a variação da condutividade térmica com a pressão for considerada ou desprezada. Utilizando-se das medidas de condutividade térmica em rochas cristalinas, a variação da condutividade térmica com a função de profundidade é estimada para áreas Pré-cambrianas e Fanerozóicas.
Shape distortion in composites: sources, characterization, and remedies
Authors: Rashid Iqra Abdul , Shaker Khubab , Nawab Yasir
Published: July 2023

This paper reviews the shape distortions in a polymer composite, its sources, characterization techniques, and remedies. The shape distortion may include warpage, spring-in, or change in enclosed diameter for flat, angled, and circular parts. Residual stresses are considered to be the major source of shape distortion (dimensional instability) in laminated composites. These stresses are the result of the difference in thermal expansion behavior of the different plies or between matrix and reinforcement. Additionally, fiber buckling, transversal cracking, and delamination are also produced in the composite, affecting its mechanical properties like tensile, flexural, and compression. The produced residual stresses are determined through different techniques like layer removal of symmetrical laminates, first ply failure, and x-ray diffraction. The common remedies for shape distortion reported in the literature include nanoparticle addition and variable thickness at the base or flanges.

Authors: Kandhro Irfan Ali , Wagan Asif Ali , Kumar Kamlesh , Shaikh Zubair Uddin
Published: July 2023

This research study focuses the cross-domain aspect-based sentiment analysis (CD-ABSA) for existing source domain annotation data. The CD-ABSA tries to use the valuable information in a source domain to extract aspect terms and evaluate their sentiment polarities in a target domain. It can considerably increase the usage of the source domain annotation resources while also reducing the workload of newer domain data annotation. one of the main components of the CD-ABSA is aspect extraction. In this paper, we utilized the most common topic modelling techniques: LDA and LSA to extract aspects from the reviews as it does not require labelled data. The topics are extracted from the education domain of the Course and Teacher Performance Evaluation (CTPE) dataset. In this paper, we also evaluated the different hyper-parameters on the CD-ABSA model and selected the best and optimal combination. The proposed methodology train on domain-dependent and independent word embedding that achieves CD-ABSA, in particularly end-to-end fashion. The experiment carries out on Academica dataset, which consists of students’ comments/feedback and SemEval-2014 dataset, which includes laptops and restaurants reviews. The evaluation metrics such as (precision, recall, F1 score and validation Accuracy) is considered while judging the LSTM classifier performance for CD-ABSA as a result.

Published: July 2023

Steel pipelines in industrial plants consist of different elements, including
seamless and/or welded (seam) pipes. Properties of welded pipes, including
their fracture behaviour, depend on the characteristics of both, the base
metal, and the weld metal. In this work, two seam pipes are considered
having different diameters and manufactured of P235TR1 steel. Hardness and
microstructure were examined on the samples which contained the seam zone,
to capture the influence of heterogeneity. Fracture resistance of the
pipeline material, i.e. of both base metals and both seams, was determined
by experimental examination of the recently proposed Pipe ring notch bending
specimens with sharp stress concentrators. Differences between the two
tested pipes, including the influence of the heterogeneity caused by the
welded joint, were determined by comparison of the crack growth resistance
curves. Effects of the initial stress concentrator shape, sharp machined
notch or fatigue pre-crack are discussed.
Fabrication of polycrystalline cubic boron nitride composites under high pressure
Authors: Mo Peicheng , Chen Jiarong , Chen Chao , Qin Haiqing , Lin Feng
Published: July 2023

The PCBN (polycrystalline cubic boron nitride) composites were synthesized by
mixing cubic boron nitride micropowders with Ti and Al micropowders at a
certain mass ratio under high temperature and ultra-high pressure
conditions. Phase composition and microstructure of the samples were
analysed by X-ray diffraction and scanning electron microscopy. The effects
of sintering temperature on the mechanical properties and microstructure of
the PCBN ceramics were investigated. It was shown that BN, AlN, TiN and TiB2
phases coexist in the PCBN ceramics fabricated at ultra-high pressure
(5.5GPa) and high temperature (1400-1500?C). With the increase of sintering
temperature, pores and gaps inside the PCBN composites gradually disappeared
and densified structure was formed. The best comprehensive mechanical
properties of the PCBN composites were obtained at 1500 ?C with a flexural
strength of 1009MPa and microhardness of 35.8GPa.

Authors: Nikitovic Zeljka , Raspopovic Zoran
Published: July 2023

Understanding plasma distribution, characteristics and phenomena is important for the development and optimization of semiconductor device manufacturing plasma equipment, such as etching and deposition tools. For this reason, plasma simulation is currently being utilized at every stage of equipment design, development and improvement. The cross section sets obtained by applying Denpoh-Nanbu theory to Ar+ on CF4 collisions were found to be in general qualitative and in part quantitative agreement with data from the literature. The Monte Carlo technique was applied to perform calculations of transport parameters. Calculated cross sections can be used to obtain transport coefficients, specially drift velocity, characteristic energy, reduced mobility, longitudinal diffusion and rate coefficients for low and moderate reduced electric fields E/N (E-electric field strength; N-gas density) and accounting for the non-conservative collisions.
The effects of hot rolling process on mechanical properties, corrosion resistance, and microstructures of Mo-Ni alloyed steels produced by powder metallurgy
Authors: Elkilani Rajab Hussein , Çuğ Harun , Erden Mehmet
Published: July 2023

This study examined the effects of hot rolling on the microstructure, tensile strength, and corrosion behaviors of three different alloy steels made by powder metallurgy: Fe-0.55C, Fe-0.55C-3Mo, and Fe-0.55C-3Mo-10Ni. 700 MPa pressure was applied to press the particles. The cold pressed samples were sintered in a mixed-gas atmosphere (90% nitrogen, 10% hydrogen) at 5?C/min up to 1400?C for 2 hours. Then, the produced steels were hot rolled with a deformation rate of 80%. The microstructures show that deformed Mo and Mo- Ni steels have finer microstructures, better mechanical properties than undeformed Mo and Mo-Ni steels, and MoC, MoN, or MoC(N) was formed in the Mo-Ni steels. The highest mechanical properties were obtained in rolled steel samples containing Mo-Ni, followed by rolled Mo steel and rolled carbon steel samples, and then unrolled samples. Additionally, Tafel curve analysis demonstrated that alloy corrosion resistance rose as Ni concentration increased. It has also been observed that the hot rolling process improves corrosion resistance. The increase in the density value with the rolling process emerged as the best supporter of corrosion resistance.

Calcium oxide from discarded eggshells and waste soda-lime-silica were utilized in this study to make wollastonite (CaSiO3) based glass-ceramics. The calcium oxide and silica were made using the melt-quenching process and sintered for 2 hours at 700 to 1000 ?C. The XRD data verified that the wollastonite crystalline peak appeared at high sintering temperatures, with crystalline phase values of 39.74%, 47.37%, and 48.91% as the sintering temperature increased at 800-1000?C, respectively. Additionally, crystalline size and phase have no obvious change at 800-1000?C, where the intensity has increased by the sintering temperature. The FTIR spectra revealed the wollastonite phase vibration at the wavelength of 501, 650, 715, 808, 931, and 2129 cm-1. Additionally, the FTIR spectral confirm the Si-O-Ca vibration band at the wavelength of 650 cm-1. For the optical sample, the value of indirect allowed transition with n=2 is the ideal value of the optical band gap based on a band gap rise from 3.89 to 4.23 eV with increasing sintering temperature. The value n=2 which is the indirect allowed transition is the optimal value of the optical band gap based on the value increase from 3.89-4.23 eV as the temperature increase. The synthesis approach introduced the low-cost method, recycle approach, simple and yet uses cheap starting materials for fabrication of wollastonite glass-ceramics product.

Although many individuals are able to achieve weight loss, maintaining this loss over time is challenging. We aimed to study whether genetic predisposition to general or abdominal obesity predicts weight regain after weight loss. We examined the associations between genetic risk scores for higher BMI and higher waist-to-hip ratio adjusted for BMI (WHRadjBMI) with changes in weight and waist circumference up to 3 years after a 1-year weight loss program in participants (n = 822 women, n = 593 men) from the Look AHEAD (Action for Health in Diabetes) study who had lost ≥3% of their initial weight. Genetic predisposition to higher BMI or WHRadjBMI was not associated with weight regain after weight loss. However, the WHRadjBMI genetic score did predict an increase in waist circumference independent of weight change. To conclude, a genetic predisposition to higher WHRadjBMI predicts an increase in abdominal obesity after weight loss, whereas genetic predisposition to higher BMI is not predictive of weight regain. These results suggest that genetic effects on abdominal obesity may be more pronounced than those on general obesity during weight regain.

Article Highlights

Nearly all individuals who intentionally lose weight experience weight regain. Individuals with a higher genetic risk for abdominal adiposity experience increased regain in waist circumference after weight loss. Genetic predisposition to higher BMI does not predict weight regain after weight loss.

Published: July 2023

Verapamil promotes functional β-cell mass and improves glucose homeostasis in diabetic mice and humans with type 1 diabetes (T1D). Now, our global proteomics analysis of serum from subjects with T1D at baseline and after 1 year of receiving verapamil or placebo revealed IGF-I as a protein with significantly changed abundance over time. IGF-I, which promotes β-cell survival and insulin secretion, decreased during disease progression, and this decline was blunted by verapamil. In addition, we found that verapamil reduces β-cell expression of IGF-binding protein 3 (IGFBP3), whereas IGFBP3 was increased in human islets exposed to T1D-associated cytokines and in diabetic NOD mouse islets. IGFBP3 binds IGF-I and blocks its downstream signaling, which has been associated with increased β-cell apoptosis and impaired glucose homeostasis. Consistent with the downregulation of IGFBP3, we have now discovered that verapamil increases β-cell IGF-I signaling and phosphorylation/activation of the IGF-I receptor (IGF1R). Moreover, we found that thioredoxin-interacting protein (TXNIP), a proapoptotic factor downregulated by verapamil, promotes IGFBP3 expression and inhibits the phosphorylation/activation of IGF1R. Thus, our results reveal IGF-I signaling as yet another previously unappreciated pathway affected by verapamil and TXNIP that may contribute to the beneficial verapamil effects in the context of T1D.

Article Highlights

Verapamil prevents the decline of IGF-I in subjects with type 1 diabetes (T1D). Verapamil decreases the expression of β-cell IGF-binding protein 3 (IGFBP3), whereas IGFBP3 is increased in human and mouse islets under T1D conditions. Verapamil promotes β-cell IGF-I signaling by increasing phosphorylation of IGF-I receptor and its downstream effector AKT. Thioredoxin-interacting protein (TXNIP) increases IGFBP3 expression and inhibits the phosphorylation/activation of IGF1R in β-cells. Regulation of IGFBP3 and IGF-I signaling by verapamil and TXNIP may contribute to the beneficial verapamil effects in the context of T1D.

Published: July 2023

Background and purpose: The use of patient-specific positioning guides (PSPGs) in total knee arthroplasty (TKA) has been advocated as a means of improving patient outcomes, but the reception of PSPGs has been mixed. The aim of our study was to compare patient-reported outcomes (KOOS, NRS-11, EQ-5D-3L, EQ-VAS) after TKA using PSPG with conventional instrumentation (CI) to determine whether there is a discernible clinical benefit to using PSPGs.Patients and methods: This multicenter randomized controlled trial (RCT) followed 77 patients who were randomly assigned to 1 of 2 cohorts between September 2011 and January 2014—one receiving TKA with PSPGs (from Materialise NV) and one receiving TKA with CI—with each cohort followed up until 5 years after the operation. The Vanguard Cruciate Retaining Total Knee System and Refobacin Bone Cement R were used in all operations. KOOS was evaluated using confidence intervals, with differences of less than 10 KOOS units between the cohorts interpreted as indicating the absence of a clinically meaningful difference.Results: No significant differences were found in any of the measured clinical outcomes—KOOS, NRS-11, EQ-5D-3L, EQ-VAS, range of motion, or radiolucent lines scoring—between the cohort operated on using PSPG and the cohort operated on using CI after 5 years of follow-up.Conclusion: There was no statistically significant effect of PSPGs on patient-reported outcomes or range of motion in TKA.

Background and purpose: Studies evaluating pain and patient-reported outcome measures (PROMs) related to type of revision total hip arthroplasty (rTHA) are sparse. Our aim was to compare pain, physical function, quality of life, and patient satisfaction among different types of aseptic rTHA at 1-year follow-up.Patients and methods: We performed a retrospective study from an institutional registry with 426 primary THAs scheduled for rTHA in a fast-track setting between 2012 and 2021. Revisions were grouped by 4 types of surgery: head and/or liner exchange, cup revision, stem revision, and cup and stem revision. Pain during mobilization and at rest (NRS 0–10), physical function (HOOS-PS and HHS) and health-related quality of life (EQ-5D) were registered preoperatively, at 3 months, and 1 year postoperatively. Patient satisfaction was surveyed at the 1-year follow-up by 2 questions related to hip function and willingness to undergo the same surgery.Results: With a response rate of 85%, all outcomes improved in the 4 groups but there were neither statistical nor clinical differences between types of rTHA at 1-year follow-up. NRS pain during mobilization improved overall by 2.7 (95% confidence interval 2.3–3.1) until 1-year follow-up, both being statistically significant and clinically relevant. The improvements were mainly seen at the 3-month follow-up, with minor progress observed at 1 year. About 80% reported improved hip function and willingness to undergo the surgery again at the 1-year follow-up.Conclusion: Significant improvements in NRS pain and PROMS were found in all groups after rTHA, with no group differences at 1 year. This is relevant preoperative information for both clinicians and patients eligible for rTHA.

Akta Pengikatan Jual Beli Tanah (PJB) umumnya dibuat dengan akta notaris. Proses pengurusan akta PJB di masa pandemi covid-19 saat ini tentu banyak mengalami kendala. Para pihak diwajibkan datang ke kantor Notaris/PPAT untuk membuat akta PJB untuk memenuhi unsur berhadapan langsung dalam akta autentik, namun karena kebijakan pemerintah yang mengharuskan untuk melakukan pyshical distancing dan bekerja dari rumah, maka kantor notaris harus tutup sehingga tidak memungkinkan untuk membuat akta PJB tersebut dengan unsur berhadapan secara langsung. Penelitian ini bertujuan untuk mengetahui urgensi penerapan cyber notary pada akta PJB di masa pandemi covid-19 dan legalitas akta PJB yang dibuat dalam konsep cyber notary di masa pandemi covid-19. Penelitian ini menggunakan metode penelitian hukum normatif melalui metode pendekatan peraturan perundang-undangan. Konsep cyber notary dapat menjadi terobosan baru pada pembuatan akta PJB di masa pandemi covid-19. Melalui cyber notary para pihak tidak perlu lagi datang ke kantor notaris untuk membuat akta PJB melainkan dapat berinteraksi secara virtual melalui media teleconference untuk memenuhi unsur berhadapan langsung. Berdasarkan penjelasan dalam UUJN-P, notaris wajib hadir secara fisik dan menandatangani akta yang dibuatnya di hadapan penghadap dan saksi. Apabila ketentuan itu dilanggar maka akan berdampak pada legalitas akta yakni akta PJB itu akan memiliki kekuatan pembuktian sebagai akta dibawah tangan.
