Published: November 2022

Micrurus dumerilii is a coral snake of clinic interest in Colombia. Its venom is mainly composed of phospholipases A2 being MdumPLA2 the most abundant protein. Nevertheless, Micrurus species produce a low quantity of venom, which makes it difficult to produce anticoral antivenoms. Therefore, in this work, we present the recombinant expression of MdumPLA2 to evaluate its biological activities and its immunogenic potential to produce antivenoms. For this, a genetic construct rMdumPLA2 was cloned into the pET28a vector and expressed heterologously in bacteria. His-rMdumPLA2 was extracted from inclusion bodies, refolded in vitro, and isolated using affinity and RP-HPLC chromatography. His-rMdumPLA2 was shown to have phospholipase A2 activity, a weak anticoagulant effect, and induced myonecrosis and edema. The anti-His-rMdumPLA2 antibodies produced in rabbits recognized native PLA2, the complete venom of M. dumerilii, and a phospholipase from another species of the Micrurus genus. Antibodies neutralized 100% of the in vitro phospholipase activity of the recombinant toxin and a moderate percentage of the myotoxic activity of M. dumerilii venom in mice. These results indicate that His-rMdumPLA2 could be used as an immunogen to improve anticoral antivenoms development. This work is the first report of an M. dumerilii functional recombinant PLA2.

Em muitos casos, a demanda por forragem ultrapassa a capacidade de regeneração das pastagens, somando-se a isso questões como uso predatório, degradação do pasto, desmatamento, queimadas, compactação e erosão. Isto evidencia a falta de um conhecimento mais aprofundado dos impactos da degradação do pasto para o solo, neste sentido, cabe considerar também que embora a irrigação da pastagem seja uma solução para a redução de custos de produção e tempo de trabalho, o ideal seria a aplicação de abordagens complementares, como o manejo correto e adubação. O que evidencia a necessidade de se encontrar alternativas para a elevação da produtividade das pastagens. Este estudo traz como objetivo analisar e comparar a implementação de adubação na pastagem, focando na realidade do Município de Presidente Figueiredo, Amazonas, e buscando atender a este objetivo, propôs-se a realização de pesquisa bibliográfica qualitativa e exploratória, apoiada em estudo de caso. Constatou-se que a adubação promoveu melhores resultados comparativamente a situação anterior, apresentando médias acima de 1,40, com duas exceções. Portanto, julga-se que a adubação permite alcançar uma redução de custos e incremento nos lucros.

Published: November 2022

Desde a sua descoberta, as vacinas possibilitaram que se evitasse várias doenças preveníveis e que se salvassem milhões de vidas. Com a pandemia do novo-Coronavírus, que se estendeu de 2019 a 2022, houve uma redução sem precedentes - a maior nos últimos 30 anos, da procura pela vacinação em várias faixas etárias, sobretudo nas vacinas de rotina para lactentes, crianças e adolescentes. Tal redução aconteceu em todo o mundo, pelo menos no início da pandemia, nas quais medidas de contenção foram mais agudamente tomadas. Com as medidas restritrivas impostas quase globalmente para diminuir a exposição e contágio, como o distanciamento social, lockdowns, interrupção de atividades laborais e outras, muitos programas de vacinação chegaram a ser temporariamente suspensos e muitas famílias deixaram de procurar manter a rotina de vacinação de seus filhos atualizada, principalmente pelo medo do contágio, mesmo após a retomada desses programas. Os efeitos disso se fazem sentir, com o reaparecimento de doenças antes controladas, como a poliomielite e o sarampo, sobretudo em países cuja cobertura vacinal já era deficitária ou insuficiente. A Organização Mundial de Saúde, e os sistemas de saúde em todo o mundo, atualmente, buscam meios de recuperar os índices vacinais prévios. O objetivo do presente trabalho, por isso, é indicar quantitativa e qualitativamente a redução de vacinações no Brasil nos anos da pandemia, 2020 e 2021, comparativamente com os dois anos anteriores, 2018 e 2019, para a faixa pediátrica menor que 1 ano.

A indústria da construção civil desempenha um papel de grande relevância na sociedade brasileira, mediante a tal importância, derivou-se a necessidade em realizar investimentos em tintas para o combate a enfermidades endêmicas. As tintas são materiais geralmente líquidos ou em pó solúvel, constituído de veículo, pigmentos, solventes e aditivos. Os aditivos são, geralmente, produtos químicos sofisticados, com alto grau de eficiência, capazes de modificar, significativamente, as propriedades da tinta. A Combartpaint 10, foi desenvolvida na Espanha pela cientista Maria Pilar Mateo Herrero, consiste em uma tinta com microcápsulas inseticidas de biopolímero que são liberadas gradualmente após a aplicação na parede.  O presente trabalho tem como objetivo apresentar de forma clara e precisa as etapas da aplicação da tinta inseticida, através de um estudo de caso na Escola Municipal CMEI Ailton Roth, localizada no município de Manaus-AM. Como metodologia adotou-se a pesquisa exploratória e qualitativa. Por fim através dos resultados obtidos, foi possível identificar, mediante ao estudo de aplicação e análise das tintas inseticidas, obtendo o conhecimento da aplicabilidade de forma correta, bem como sua reologia, desempenho da tinta e comportamento de escorrimento, dessa forma comprovando a eficácia da tinta inseticida.

Encefalopatia traumática crônica (ETC) é uma neuropatia expressada como um quadro demencial cuja clínica envolve declínio cognitivo e mudanças graves comportamentais. A ETC pode se estabelecer após concussões repetitivas que costumeiramente ocorrem em esportes com alto índice de contato; dentre esses os de maiores riscos se enquadram o boxe e o futebol americano. A ETC, assim como sua gravidade, são proporcionais à idade e quantidade de impactos. Portanto, sugere-se que essa moléstia e seus déficits sejam causados pelo efeito acumulativo de traumatismos cranioencefálicos (TCEs) leves que causam up-regulation da proteína precursora do peptídeo beta amilóide e da proteína TAU, que consequentemente forma emaranhados neurofibrilares. O acúmulo de ambas substâncias geram modificações anatômicas estruturais (macro e microscópicas) e desencadeiam os sinais e sintomas neuropsiquiátricos. Dessa forma, a ETC pode ser confundida com outros tipos de demências, entre elas a Doença de Alzheimer. Visto que se trata de uma condição clínica complexa, é importante estabelecer um diagnóstico precoce e promover uma conduta clínica de maneira precisa, com o intuito de amenizar os danos e os prejuízos cognitivos gerados. A gravidade e a irreversibilidade da ETC deveriam nortear a prática esportiva com cuidados de múltiplas perspectivas, prevenindo, assim, as consequências geradas por essa condição.

As projeções demográficas tornam cada vez mais evidente o crescente envelhecimento da população brasileira. Diante desse quadro e da pandemia, é natural que as autoridades públicas e a sociedade, como um todo, comecem a ter uma maior preocupação com a qualidade de vida das pessoas com idade mais avançada. Por meio deste trabalho esperou-se avaliar a influência da pandemia sobre a qualidade de vida dos idosos, a alteração ou manutenção dos exercícios físicos durante este período nos grupos ativos e sedentários, bem como identificar os fatores que motivaram sua permanência regularmente e as principais barreiras que dificultaram a adesão no grupo sedentário. Este estudo é de natureza exploratório-descritiva, transversal e de abordagem quanti-qualitativa. Os dados foram coletados e analisados por meio do questionário SF-36  e outro socioeconômico, elaborado pelo próprio grupo de pesquisa e também pela análise estatística por meio dos métodos Shapiro-Wilk e Wilcoxon. No quesito Qualidade de Vida, as pontuação dos domínios AE, CF e LAF reduziram comparativamente a antes e  durante a pandemia. No grupo ativo, 16,3% relataram ter reduzido a frequência com que praticavam suas atividades. Já o grupo sedentário (28,6%) continuou a não praticar exercícios físicos. Os idosos sedentários justificaram o desânimo e a falta de coragem (16%) como principais fatores dificultadores à adesão. Portanto, alguns aspectos da qualidade de vida dos idosos piorou durante a pandemia. Houve redução na frequência na prática de atividades físicas entre o grupo ativo, sendo que o grupo sedentário permaneceu na mesma condição.

A automedicação configura-se como um problema de saúde pública, e o uso racional pode poupar recursos nos casos de tratamento e de terapêutica para doenças menores. Segundo a OMS, metade de todos os fármacos é prescrita de forma incorreta, além de vendida e dispensada também de forma equivocada. Nesta pesquisa objetivou-se conhecer os hábitos de automedicação e fatores que influenciam essa prática, caracterizando o perfil do grupo a partir dos dados sociodemográfico, frequência, necessidade de prescrição, busca informativa, motivos e tipos de medicações em uso no contexto da automedicação entre os pacientes atendidos pelo Ambulatório da Faculdade de Ciências da Saúde (FACS) da Universidade do Estado do Rio Grande do Norte. Tratou-se de um estudo de corte transversal com abordagem qualitativa realizado com pacientes que frequentam os ambulatórios de especialidades da Universidade. A coleta deu-se por meio da realização de uma entrevista semiestruturada. O perfil dos pacientes entrevistados mostra-se majoritariamente utilizador de sintomáticos, com notoriedade para as queixas de dores gerais e cefaleia, com prevalentes de caracteres adultos, do sexo feminino, casado, procedentes da mesma cidade onde se localiza o serviço ambulatorial pesquisado. Enquadra-se em sua maior quantidade no serviço de ginecologia e obstetrícia, que se automedicam em tempos atuais, sem prescrição habilitado. Apesar do balconista de farmácia ter sido o mais mencionado como recomendado dos medicamentos, não foi, paradoxalmente, o ente mais procurado para busca de informações sobre os medicamentos. A automedicação ainda consiste em um grave dilema da saúde pública nacional e global, e seu uso indiscriminado pela população caracteriza-se deletério sob a ótica de inúmeros problemas físicos e psicossociais. Em estudos posteriores, sugere-se que o mapeamento demográfico, social, cultural e com os traços do perfil “consumístico” medicamentoso seja ampliado.

Published: November 2022

A Agenda 2030, enquanto um plano de ação global, assumido pelo Brasil e mais 192 países para efetivar os direitos humanos e para promover o desenvolvimento sustentável, ainda é pouca conhecida e trabalhada no processo de formação docente, bem como a Carta da Terra, outro tratado importante que este ano fez 21 anos. O presente trabalho avaliou o grau de engajamento no ensino fundamental final II, frente a Agenda 2030 e a Carta da Terra, utilizando o tema mudança climática, por um modelo de questionário que compreende cinco fatores: conhecimento, atitude, preocupação, responsabilidade e atividade. Como tornar estes tratados internacionais aplicáveis nas salas de aula e qual o nível de engajamento dos alunos de Ciências do Ensino Fundamental Final II possuem com o tema proposto? A educomunicação foi usada como fundamentação teórica para entender o processo de formação dos alunos. As aulas aconteceram via agendamentos das escolas.  O questionário foi aplicado dentro de uma instituição do terceiro setor, Instituto Ekko Brasil (IEB), que trabalha com um programa ambiental denominado PAIE (Programa de Atendimento as Instituições de Ensino, Pesquisa e Extensão). No total, 45 questionários foram preenchidos e validados. Destes, 27 foram preenchidos por estudantes do gênero feminino, entre 12 e 14 anos, e 18 do gênero masculino, de 13 a 15 anos. Os dados obtidos indicam que 98% dos estudantes desconhecem a Agenda 2030 e a Carta da Terra e 77% afirmam que não é de sua responsabilidade agir de forma favorável ao clima. Os dados foram disponibilizados pelo IEB, que tratou do tema com estudantes da rede pública e privada de ensino da Grande Florianópolis na forma de aulas assíncronas, no espaço educomunicativo, mantido dentro do Centro de Pesquisa da Instituição.

Multi-key Fully Homomorphic Encryption without CRS from RLWE
Authors: Luo Fucai
Published: November 2022

Fully Homomorphic Encryption (FHE) is a powerful encryption system in cloud computing that allows homomorphic computations on encrypted data without decrypting them. Multi-key fully homomorphic encryption (MFHE), as an extension to FHE, allows homomorphic computations on ciphertexts encrypted under different keys.   However, most MFHE schemes require a Common Random\slash Reference String (CRS), while the few that do not are based on the Learning With Errors (LWE) problem, which means that they can only deal with single bit plaintext.  Consequently, MFHE schemes based on the Ring Learning With Errors (RLWE) problem are more desirable, as they can handle polynomial plaintext.  Requiring the CRS seems to weaken the semantic definition of MFHE, where all users generate their own keys independently.

In this paper, we study the RLWE-based MFHE in the CRS model and propose the first RLWE-based MFHE without CRS.   To this end, we remove the CRS by designing a new relinearization algorithm.  Like previous MFHE schemes, our RLWE-based MFHE without CRS has a simple 1-round threshold decryption, which implies a $3$-round secure MPC protocol in the plain model from the RLWE assumption.

ENGINEERING THE NaYF4:Yb3+/Tm3+ UPCONVERSION NANOPARTICLE LUMINESCENCE ENERGY TRANSFER FOR A RATIOMETRIC pH INDICATOR
Authors: Nguyen Nhat Nam
Published: November 2022

Fluorescent dye 8-hydroxypyrene-1,3,6-trisulfonic acid (HPTS) is used to develop a ratiometric pH indicator based on NaYF4:Yb3+/Tm3+ upconversion nanoparticles (UCNPs). HPTS was functionalized onto the UCNP surfaces via a modified co-condensation silica coating (UCNP@SiO2-HPTS). The as-prepared UCNP@SiO2-HPTS core-shell nanostructure was characterized with transmission electron microscopy, scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy (FT-IR), and photoluminescence spectroscopy. Luminescence resonance energy transfer (LRET) from NaYF4:Yb3+/Tm3+ UCNP to HPTS was found to exhibit pH-sensitivity simultaneously under near-infrared (NIR) irradiation (λ = 980 nm).

The governing partial differential equations are solved in the spatial coordinate by Navier solution. Those Numerous micromechanical models have been examined to attain the effective material properties of the two-phase FGM plate. The numerical results are compared with those given by other model existing in the literature to confirm the accuracy of the (HSDT). The present results are in good agreement with all models studied of homogenization for all values of the material index and all geometry configurations of the FG-sandwich plates.

Training as a Tool for Service Delivery: A Case Study of Health Care Workers in Gwanda, Zimbabwe
Authors: Kanyumba Blessing
Published: November 2022

The healthcare sector across most global south countries is challenged by various issues and this includes poor service delivery. The delivery of quality service within healthcare institutions is complicated by unprecedented emigration of healthcare workers to the global north. The other challenges include, poor funding and infrastructure, limited medical resources, equipment, and shortage of health care experts. As such this study examines how on and off the job training of healthcare workers impact service delivery. Adopting a quantitative paradigm, the paper identifies the training provided to healthcare workers and examines the effectiveness of the training for effective service delivery. A closed-ended structured questionnaire was used to elicit responses from 80 healthcare workers at Manama Mission Hospital in Gwanda, Zimbabwe. Findings revealed that practical hands-on experience (on-the-job training) supported with effective supervision and guidance from more experienced health workers aids effective service delivery. Training targeted at effective service delivery, constant assessment, and provision of constructive feedback from senior staff members are crucial measures for an effective healthcare system. Beyond constant training, measures must be put in place to ensure the retainment of healthcare experts within the country as an overstretched healthcare system will continue to battle with ineffective service delivery. This study adds to the body of knowledge related to employee training of healthcare workers within Zimbabwe.
Macroscale effects of the Monument Fire on suitable habitat of the Trinity bristle snail in the Greater Trinity Basin, Klamath Bioregion, northern California
Authors: Sullivan Robert M.
Published: November 2022

I evaluated the impact and extent of the Monument Fire on the geographic range and suitable macrohabitat of the Trinity bristle snail (Monadenia setosa), a California endemic with limited distribution in northern California. Total area burned by the fire was ~87,984 ha or 46.0% of the species range (n = 191,156 ha). Total area of suitable macrohabitat for the species is ~107,913 ha of which 44.5% (n = 47,962 ha) was encompassed by the fire. Results show that the total area of forest cover-type vegetation and individual forest stand attributes impacted by the fire was not significantly different from areas within the species range not burned by the fire. There was no significant proportional differences in the six sequential categories of suitable macrohabitat burned by the fire (i.e., Low, Low-moderate, Moderate, Moderate-high, High, Critical suitability). The percentage of Moderate and Moderate-high suitable macrohabitat burned was only somewhat greater than predicted by the pre-fire species habitat suitability model (HSM). Many individual watersheds were encompassed by the fire and the resulting mosaic of burned watersheds was highly variable. Application of the Soil Burn Severity (SBS) map identified 8,293 ha (17.3%) of Unburned or very low burned soil, 24,191 ha (50.5%) of Low burned soil, 13,998 ha (29.2.1%) of Moderately burned soil, and 1,460 ha (3.0%) of Highly burned soil within the boundaries of the Monument Fire. When applied to categories of suitable macrohabitat, I calculated that 31,096 ha (100%) of Low to Low-moderate and 13,998 ha (96.1%) of Moderate to Moderate-high suitable macrohabitat were burned. High and Critical areas of macrohabitat suitability were much less impacted by high SBS (n = 1,461 ha [58.0%] because these regions were small in size, highly fragmented, widely dispersed across the landscape, and separated by major topographic and riverine discontinuities.

A universally applicable method of calculating confidence bands for ice nucleation spectra derived from droplet freezing experiments
Authors: Fahy William D. , Shalizi Cosma Rohilla , Sullivan Ryan Christopher
Published: November 2022

Abstract. A suite of generally applicable statistical methods based
on empirical bootstrapping is presented for calculating uncertainty and
testing the significance of quantitative differences in temperature and/or
ice active site densities between ice nucleation temperature spectra derived
from droplet freezing experiments. Such experiments are widely used to
determine the heterogeneous ice nucleation properties and ice nucleation
particle concentration spectra of different particle samples, as well as in
studies of homogeneous freezing. Our methods avoid most of the assumptions
and approximations inherent to existing approaches, and when sufficiently
large sample sizes are used (approximately >150 droplets and
>=1000 bootstrap samples in our system), can capture the full
range of random variability and error in ice nucleation spectra.
Applications include calculation of accurate confidence intervals and
confidence bands, quantitative statistical testing of differences between
observed freezing spectra, accurate subtraction of the background filtered
water freezing signal, and calculation of a range of statistical parameters
using data from a single droplet array freezing experiment if necessary. By
providing additional statistical tools to the community, this work will
improve the quality and accuracy of statistical tests and representations of
uncertainty in future ice nucleation research, and will allow quantitative
comparisons of the ice nucleation ability of different particles and
surfaces.
Mineralization of autochthonous particulate organic carbon is a fast channel of organic matter turnover in Germany's largest drinking water reservoir
Authors: Dordoni Marlene , Seewald Michael , Rinke Karsten , Friese Kurt , van Geldern Robert , Schmidmeier Jakob , Barth Johannes A. C.
Published: November 2022

Abstract. Turnover of organic matter (OM) is an essential ecological
function in inland water bodies and relevant for water quality. This is
especially important for the potential of dissolved organic carbon (DOC)
removal as well as for emissions of CO2. In this study, we investigated
various phases of OM including DOC, autochthonous particulate organic carbon
(auto-POC), allochthonous particulate organic carbon (allo-POC), and
sedimentary matter (SED) in a temperate drinking water reservoir (Rappbode
Reservoir, Germany) by means of dissolved inorganic carbon (DIC)
concentrations and carbon stable isotope ratios. In order to best outline
carbon turnover, we focused on the metalimnion and the hypolimnion of the
reservoir, where respiration is expected to be dominant and hardly disturbed
by atmospheric exchange or photosynthesis. DIC concentrations ranged between
0.30 and 0.53 mmol L−1, while δ13CDIC values ranged
between −15.1 ‰ and −7.2 ‰ versus the VPDB (Vienna PeeDee
Belemnite) standard. Values of δ13CDOC and δ13Cauto-POC ranged between −28.8 ‰ and −27.6 ‰
and between −35.2 ‰ and −26.8 ‰, respectively. Isotope
compositions of sedimentary material and allochthonous POC were inferred
from the literature and from measurements from previous studies with δ13CSED=-31.1 ‰ and δ13Callo-POC ranging from −31.8 ‰ to −28.6 ‰. Comparison of DIC concentration gains and stable
isotope mass balances showed that auto-POC from primary producers was the
main contributor to increases in the DIC pool. Calculated OM turnover rates
(0.01 to 1.3 µmol L−1 d−1) were within the range for
oligotrophic water bodies. Some higher values in the metalimnion are likely
due to increased availability of settling auto-POC from the photic zone.
Samples from a metalimnetic oxygen minimum (MOM) also showed dominance of
respiration over photosynthesis. Our work shows that respiration in
temperate lentic water bodies largely depends on auto-POC production as a
major carbon source. Such dependencies can influence the vulnerabilities of
these aqueous systems.
All models are wrong, but are they useful? Assessing reliability across multiple sites to build trust in urban drainage modelling
Authors: Pedersen Agnethe Nedergaard , Brink-Kjær Annette , Mikkelsen Peter Steen
Published: November 2022

Abstract. Simulation models are widely used in urban drainage engineering and research, but they are known to include errors and uncertainties that are not yet fully realised. Within the herein developed framework, we investigate model adequacy across multiple sites by comparing model results with measurements for three model objectives, namely surcharges (water level rises above defined critical levels related to basement flooding), overflows (water levels rise above a crest level), and everyday events (water levels stay below the top of pipes). We use
multi-event hydrological signatures, i.e. metrics that extract specific
characteristics of time series events in order to compare model results with the observations for the mentioned objectives through categorical and
statistical data analyses. Furthermore, we assess the events with respect to sufficient or insufficient categorical performance and good, acceptable, or poor statistical performance. We also develop a method to reduce the
weighting of individual events in the analyses, in order to acknowledge
uncertainty in model and/or measurements in cases where the model is not
expected to fully replicate the measurements. A case study including several years of water level measurements from 23 sites in two different areas shows that only few sites score a sufficient categorical performance in relation to the objective overflow and that sites do not necessarily
obtain good performance scores for all the analysed objectives. The
developed framework, however, highlights that it is possible to identify
objectives and sites for which the model is reliable, and we also suggest
methods for assessing where the model is less reliable and needs further
improvement, which may be further refined in the future.

Published: November 2022

Abstract. In recent decades, multiple researchers have produced landslide susceptibility maps using different techniques and models, including the
information value method, which is a statistical model that is widely
applied to various coastal environments. This study aimed to evaluate
susceptibility to landslides in the Essaouira coastal area using bivariate
statistical methods. In this study, 588 distinct landslides were identified, inventoried, and mapped. Landslides are performed by
means of observation and interpretation of different data sources, namely high-resolution satellite images, aerial photographs, topographic maps, and extensive field surveys. The rocky coastal system of Essaouira is located in the middle of the Atlantic coast of Morocco. The study area was split into 1534 cliff terrain units that were 50 m in width. For training and validation purposes, the landslide inventory was divided into two independent groups: 70 % for training and 30 % for validation. Twenty-two layers of landslide conditioning factors were prepared – namely, elevation, slope angle, slope aspect, plan curvature, profile curvature, cliff height, topographic wetness index, topographic position index, slope over area ratio, solar radiation, presence of faulting, lithological units, toe lithology, presence and type of cliff toe protection, layer tilt, rainfall, streams, land-use patterns, normalised difference vegetation index, lithological material grain size, and presence of springs. The statistical relationship between the conditioning factors and the different landslide types was calculated using the bivariate information value method in a pixel-based model and in the elementary terrain units-based model. Coastal landside susceptibility maps were validated using landslide training group partitions. The receiver operating characteristic curve and area under the curve were used to assess the accuracy and prediction capacity of the different coastal landslide susceptibility models. Two methodologies, considering a pixel-based approach and using coastal terrain units, were adopted to evaluate coastal landslide susceptibility. The results allowed for the classification of 38 % of the rocky coast subsystem as having high susceptibility to landslides, which were mostly located in the southern part of the Essaouira coastal area. These susceptibility maps will be useful for future planned development activities as well as for environmental protection.

Abstract. Understanding the alterations in spatial–temporal water level dynamics caused by natural and anthropogenic changes is essential for water resources management in estuaries, as this can directly impact the estuarine morphology, sediment transport, salinity intrusion, navigation conditions, and other factors. Here, we propose a simple triple linear regression model linking the water level variation on a daily timescale to the hydrodynamics at both ends of an estuary. The model was applied to the upper Yangtze River estuary (YRE) to examine the influence of the world's largest dam, the Three Gorges Dam (TGD), on the spatial–temporal water level dynamics within the estuary. It is shown that the regression model can accurately reproduce the water level dynamics in the upper YRE, with a root mean squared error (RMSE) of 0.061–0.150 m seen at five gauging stations for both the pre- and post-TGD periods. This confirms the hypothesis that the response of water level dynamics to hydrodynamics at both ends is mostly linear in the upper YRE. The regression model calibrated during the pre-TGD period was used to reconstruct the water level dynamics that would have occurred in the absence of the TGD's freshwater regulation. Results show that the spatial–temporal alterations in water levels during the post-TGD period are mainly driven by the variation in freshwater discharge due to the regulation of the TGD, which results in increased discharge during the dry season (from December to March) and a dramatic reduction in discharge during the wet-to-dry transitional period. The presented method to quantify the separate contributions made by changes in boundary conditions and geometry to spatial–temporal water level dynamics is particularly useful for determining scientific strategies for sustainable water resources management in dam-controlled or climate-driven estuaries worldwide.

PLS – SEM digunakan untuk menguji secara simultan hubungan antar konstruk laten dalam hubungan linear ataupun nonlinear dengan banyak indicator baik berbentuk reflektif dan formatif.Hasil  analisis  moderasi  dengan  melihat nilai P-value menunjukkan bahwa preferensi risiko tidak memoderasi hubungan pemahaman perpajakan terhadap  kepatuhan  wajib. Hal  ini berarti  bahwa wajib  pajak belum memahami  khususnya  pemahaman  dasar  mengenai  pajak  agar wajib pajak dapat mempertimbangkan segala sesuatu sebelum melakukan pembayaran  pajak karena  pemahaman  pajak  menjadi  faktor  yang  sangat penting  dalam  membantu  wajib  pajak  melaksanakan tingkat  kepatuhan wajib pajak. Sedangkan Hasil  analisis  rmoderasi  dengan  pendekatan  nilai  p-value menunjukkan bahwa preferensi risiko memoderasi hubungan sanksi perpajakan  terhadap  kepatuhan  wajib. Hal  ini  berarti  bahwa masyarakat pada  umumnya akan patuh  pada  peraturan apabila  ada  sanksi yang mengikat, Selain  itu  hal  yang  harus  diperhatikan  wajib  pajak  dalam melakukan pembayaran pajak adalah risiko. Karena Semakin tinggi sanksi  yang  diberikan  maka  akan  menghasilkan  kepatuhan  yang  tinggi pula.

¿Cuáles son los principales enfoques desde donde se está desarrollando la investigación de materiales DIY en el campo del diseño industrial? Con el presente artículo informamos los resultados de la revisión que ubica lugares epistemológicos y metodológicos desde los que estudios en materiales DiY hablan en el panorama actual de la investigación en diseño, triangulando métodos de análisis cualitativo y análisis de redes sociales -ARS-, tanto desde los estudios sociales como desde los enfoques emergentes de la investigación en diseño, encontrando que su posicionamiento está disperso entre el pos-positivismo, el enfoque participativo, el diseño crítico, el diseño centrado en el usuario, el diseño emocional y el enfoque generativo-participativo de estudios en diseño. Lo anterior, refleja la gran variedad de temas desarrollados en el campo, al tiempo que devela escasa cohesión en la co-producción de nuevo conocimiento que caracteriza la red de autores, hecho que se constituye en oportunidad para conectar intereses por medio de la indagación inter-transdisciplinar desde la diversidad de localizaciones geográficas, proyectando la investigación en materiales DiY hacia prácticas de diseño participativo, combinando saberes y sentires locales de las comunidades con conocimientos técnicos y disciplinares del diseño, jugueteando con nuevas aristas expresivo-sensorio-emocionales del diseño orientado a los materiales.
The Future of Creating Jobs for Vietnamese Workers after Covid-19 Pandemic
Authors: Ha Dao Ngoc , Huong Nguyen Thi Thu , Anh Nguyen Tuan
Published: November 2022

The picture of the global economy has experienced a tumultuous year with "dark colours" as the dominant colour due to the severe impact of the Covid-19 pandemic. In December 2020, a vaccine against the acute respiratory infection Covid-19 was released to help control the pandemic and restore economic activity. The world economy has shown significant signs of recovery. Hence, the International Labour Organization (ILO) said that the labour market has begun to recover after unprecedented disruptions caused by the Covid-19 pandemic in 2020. However, the negative impact of the pandemic is still ongoing. The organization's Covid-19 Impact Report provides the latest figures showing that global working hours in 2020 have decreased by 8.8% compared to Q4 2019. This decline includes the number of working hours reduced for those still employed and those who lost their jobs. Notably, about 71% of people who lost their jobs (equivalent to 81 million people) decided to leave the labour market instead of looking for another job and becoming unemployed (GSO, 2021). This article focuses on analyzing the current situation of job creation for Vietnamese workers after Covid-19, pointing out the achieved results, limitations, causes and some recommendations to promote job creation for Vietnamese workers in the post-Covid-19 context.

5G advanced technology has introduced innovative multimedia services, thus propelling the rise of the mobile multimedia market. While the ubiquity of mobile multimedia services has boosted customer convenience, it has also unlocked the way to possible security concerns that potentially damage users’ privacy and service providers’ properties. Several standards and researches have been proposed to counter these threats, notably those concentrating on authentication between users and service applications. Unfortunately, these studies are limited to address a new challenge, secure handover among distributed application functions in 5G Multi-access Edge Cloud (MEC) environments. Motivated by this, we present a handover authentication protocol with push-key and pull-key optimization options in 5G mobile multimedia application services. The proposed protocol provides mutual authentication, secure key exchange, confidentiality, and integrity. Furthermore, it also supports perfect forward secrecy, optimal handover, and anonymity, which were not previously considered in prior studies. While formal verification through BAN Logic and Scyther proved that the protocol is secure against attacks that violate the supported security requirements, comparative analysis of the proposed protocol against existing studies demonstrates that the protocol is simultaneously efficient.

Published: November 2022

Rapid and accurate monitoring of the dynamic change of construction land is of great significance for strictly controlling the arbitrary growth of urban construction land and protecting agricultural and forestry land. In order to master the situation of land use change and conduct more efficient research on urban land use classification, this paper takes Weinan as the research object and uses Landsat8 data under the same classification conditions to analyze the image features of various land use types respectively by using minimum distance, maximum likelihood and random forest method, and carries out land use classification research. The research shows that for the selected research area, the maximum likelihood classification method has higher classification accuracy and time efficiency, while the minimum distance and random forest can not reflect its superior classification performance, and the overall accuracy is lower than the maximum likelihood classification method, and the maximum likelihood classification method has obvious advantages. Therefore, in the classification of remote sensing image, the maximum likelihood classification method is suitable when the data dimension is low.
