The purpose of the study was to identify the mainstream journalistic competencies which are demanded by the employment market today.

Research methods. With the help of content analysis of vacancy announcements for journalists, the most frequent professional requirements addressed to applicants by employers for the relevant positions were identified. The sample consisted of vacancy advertisements from two popular job search websites work.ua and ua.jooble.org with a total of 70 text units. The chronological boundaries of the sample amounted to 1 month. Territorial borders are the cities of Dnipro and Kyiv. The identified professional requirements were systematised on the basis of Z. Weischenberg competency model supplemented by the latest journalistic competencies, which were updated in connection with the needs of the time. Methods of analysis such as synthesis and generalisation were used to interpret the results of content analysis.

Results. The conducted content-analytical research allowed to draw conclusions about the ratio of both established and new competencies that characterise the journalistic profession. It was found that journalistic skills, represented by a number of instrumental skills, define all the types of journalistic positions, regardless of specialisation and functional features. The results of the content analysis also allowed us to state the interest of employers in the skills required when working in cross-media and social networks. Higher education as a requirement for candidates was presented in less than 50% of advertisements, while the experience was updated in almost 80% of the analysed vacancies. These data correlate with today’s popular approaches to the deinstitutionalisation of journalism education, its transfer to the practical-applied field. In the United States, in particular, it is presented by the model of education as a training hospital, while in Germany it is built in accordance with the Dortmund model. It is stated that the practice of opening of media-based schools of journalism is gradually being introduced in Ukraine.

Novelty. For the first time, professional requirements for journalists were systematised on the basis of content analysis of vacancy advertisements. Competency priorities of employers were revealed.

Practical significance. The results and conclusions can be used to optimise the competency model of journalism education.

Published: March 2022

The digital age fueled the rise of Filipino internet users through text messaging and interacting through social media. In addition, users took advantage of the potential of the internet by conducting transactions online, such as purchasing, selling, and advertising products and services. Electronic commerce or e-commerce is becoming a global phenomenon, with more people opting to purchase goods and services online. E-commerce has also opened many opportunities for businesses to launch online. A wide array of products and services are being sold online, such as clothing items, home essentials, etc. The pandemic which caused restrictions in going out led to online wet markets gaining popularity. A wet market or palengke is a public market place where fresh produce, poultry, meat, fish, etc., are sold. The rise of online wet markets allowed people to purchase and receive fresh food items without having to leave the comforts of their homes. This also allows them to avoid going out and conform to existing protocols during quarantine. The study will use descriptive statistics in examining the relationship of website quality dimensions: quality of information, quality of interaction, usability, and consumer purchase intention of residents in Caloocan City. Some of the respondents were randomly selected to give intuition on the improvement of the existing research paper. The relationship between website quality and perceived risk may be deduced: the greater the website quality, the lower the perceived risk. Respondents' level of security in disclosing their information when making a transaction in an online wet market was regarded as a risk. In addition, the study found that online quality had a considerable impact on consumers' purchasing intentions. Customers' perceived risk is not taken into account when anticipating their intentions.

In current study, the production of biosurfactant by Cunninghamella elegans UCP 0542 in food industry waste-based medium was investigated as a biotechnological strategy to reduce the bioprocess costs. Cultivation of the Mucoralean fungus was performed in 3 L Fernbach flasks containing 1.5 L of effective volume of medium composed by 2% instant noodle waste, 2% corn steep liquor and 0.5% post-frying soybean oil, with carbon/nitrogen ratio of 30:1. Fermentations were carried out during 96 h and 28ºC, at 150, 180 and 200 rpm, in order to evaluate the influence of orbital agitation in biosurfactant production. The properties of surface tension reduction, emulsification and dispersion were investigated. According to the obtained results, C. elegans produced biosurfactant in sustainable medium, reducing the surface tension from 71 to 27.5 mN/m after cultivation at 200 rpm. Biotensoactive produced in this condition formed stable emulsions with engine oil and burnt engine oil (emulsification index of 100%) and showed 48.39 cm² of oil dispersion area (ODA) with burnt engine oil. The biomolecule was isolated by different methodologies, reaching a maximum yield of 2.1 g/L with ethanol. The biosurfactant produced by C. elegans exhibited excellent potential for application in bioremediation processes considering its promising properties as a surface tension reducing agent, emulsifying and dispersing action of petroderivatives.

Beside the acute respiratory syndrome caused by COVID-19, the exacerbated inflammatory process leads to systemic coagulation disorders, acute cardiovascular disorders, acute renal failure, metabolic changes and other clinical manifestations, increasing the mortality of patients with severe forms of the disease. The development of effective vaccines and drugs for the adequate treatment of severe forms of the disease has become a priority for the scientific and medical community. Likewise, the discovery of possible predictors for the early identification of severe cases with a high risk of death are constantly being sought. Laboratory tests, such as blood count, coagulation tests, hormonal and biochemical tests, are performed on a daily basis in the hospital environment and have proved to be very useful in the search for these indicators. In our study, we evaluated the laboratory tests of 398 positive and negative patients for COVID-19 admitted to hospitals in Uberaba, from the Macroregion of Triângulo Sul, state of Minas Gerais, with a population of 800,000 inhabitants. In our results, it was observed that the patients who died presented anemia, neutrophilic leukocytosis, increased CRP, urea and creatinine from the 5th, 6th day of symptoms, and with lymphopenia on the 1st day. In blood gas analysis, pH, SaO2 and PO2 were reduced since the 1st day of symptoms in patients who died, and the pH remained reduced until the clinical outcome. Changes were also found in the dosage of LDH, aPTT, albumin and electrolytes. Given these results, laboratory tests can be useful as predictive signs of severity in the early days of symptoms.

Published: March 2022

The effects of transgenes on plant resistance to non-target diseases caused by foliar fungi are still poorly studied. This study aimed to evaluate the indirect effects of the TC1507 event, isolated and in combination with NK603, on the maize genetic resistance to northern leaf blight, in the presence and absence of chemical control of weeds. Three isogenic hybrids were used as treatments in this study: the non-genetically modified conventional hybrid BG7060 (NGM); the genetically modified hybrid BG7060H (Hx), carrying transgenes cry1F and pat (TC1507 event); and the genetically modified hybrid BG7060HR (Hxrr), carrying transgene cp4epsps (NK603 event) combined with the TC1507 event. To evaluate the resistance of the three isogenic hybrids to that pathogen, three experiments were carried out in Florianópolis, southern Brazil, in complete randomized blocks with three replications in experiment 1 (2012/2013 harvest) and four replications in experiments 2 and 3 (2016/2017 harvest). The control of weeds was done by manual weeding, in experiments 1 and 2, and with the application of the herbicide Finale in a single dose, in experiment 3. The severity of northern leaf blight was evaluated under natural conditions of disease occurrence, in experiment 1, and from inoculation of the pathogen, in experiments 2 and 3. The isogenic hybrid Hxrr showed higher incidence and shorter incubation and latency periods than the Hx and conventional isogenic hybrids in the two management environments of weeds. Pathogen resistance, measured from these three variables, tended to be lower in the genetically modified hybrid Hxrr, which contains two events (TC1507 and NK603), followed by the hybrids Hx and NGM, in increasing order of resistance. The addition of the herbicide for the control of weeds increased the susceptibility of the genetically modified hybrids Hx and Hxrr, as well as the conventional hybrid not submitted to this control, but cultivated close to the hybrids Hx and Hxrr managed with the use of the herbicide.

O presente estudo analítico controlado, prospectivo e com mascaramento duplo-cego, teve o objetivo de (1) verificar se adultos com estresse visual, avaliados por um rastreador ocular, quando comparados a um grupo controle, apresentam diferença nos movimentos oculares durante a leitura de textos e (2) prover fontes de evidências de validade da estrutura interna para o Questionário de Caracterização de Dificuldades Visuais e de Aprendizagem. Participaram adultos com estresse visual (GEV; n = 16) pareados com um grupo controle sem estresse visual (GC; n = 24). Para as análises do rastreador ocular com tecnologia de infravermelho, cada participante realizou a leitura de dezesseis textos, apresentados de forma randômica, tendo o GEV realizado 239 leituras e o GC 342 leituras. Para o estudo de validação do questionário, foram adicionados retrospectivamente os prontuários de 291 adultos atendidos consecutivamente. Os resultados mostraram diferenças significativas entre os GEV e o GC com relação a: Fixação, Regressão, Duração da Fixação, Ataque Direcional, Taxa de leitura, Eficiência de leitura, Correlação cruzada, Anomalias de Fixação e Anomalias Binoculares. Esses resultados demonstram que o GEV, quando comparado ao GC, apresentou uma oculomotricidade menos eficiente, com pior correlação cruzada e maior número de Anomalias Binoculares, o que evidencia movimentos em direções opostas e dificuldade na coordenação binocular. O Questionário mostrou-se adequado na análise fatorial, o que adiciona evidências de validade da estrutura interna. Esses achados reforçam que os leitores com estresse visual apresentavam dificuldades oculomotoras na leitura.

A Restrição do Crescimento Intrauterino (RCIU) é uma complicação importante da gravidez, devido a taxas elevadas de morbidade e mortalidade perinatal. Esta complicação é definida como um feto que não consegue atingir seu percentual de crescimento, ocasionado por fatores maternos e placentários. Desta forma, este estudo teve como objetivo avaliar os determinantes maternos e placentários, bem como especificar os métodos diagnósticos e os possíveis desfechos diante da RCIU. Foi realizada uma revisão de literatura nas bases de dados PubMed, SCIELO e BVS, tendo como critérios de inclusão: artigos publicados no período de 2010 a 2022 no idioma em português e inglês. Sendo encontradas 16 publicações elegíveis para inclusão desta revisão. Diante da análise da literatura notou-se que são vários os determinantes causadores da RCIU, como: a idade, estado nutricional, hipertensão, doença renal crônica, diabetes, uso de drogas ilícitas, tabaco, etnia, anemia, implantação anormal da placenta, artéria umbilical única, placenta prévia, anormalidades uterinas, placenta circunvalada, infartos da placenta e entre outros. Para identificação do feto com este retardo é utilizado a medida da altura uterina (AU), a ultrassonografia obstétrica, a estimativa do peso fetal (PEE) e o Doppler da artéria umbilical. Quanto aos possíveis resultados diante desta patologia pode acarretar prováveis complicações ao recém-nascido e na infância, condizentes a alterações na condição de saúde. Assim, conclui-se que são múltiplos os fatores relacionados a RCIU e que a identificação das principais alterações envolvidas pelos métodos diagnósticos é de fundamental importância para evitar problemas na saúde do feto e da gestante.

The design was completely randomized, where five soybean varieties were grown: 8579R5F; 84I86; M8644IPRO; DM80I79; 81I81 and with four replicates, totaling 20 plots or pots. The cultivar 8579R5F stood out in the development parameters in number of trifoliate (NT), shoot dry mass (DMAP) and also in the concentrations of chlorophylls A and B. The cultivar M8644IPRO showed the highest internal leaf morphology parameters for phloem diameter (PD) and palisade parenchyma thickness (PPT). Chlorophyll A and B concentrations present correlations with positive linear responses with shoot dry mass. Stomatal functionality (SF) and phloem diameter (PD) present correlations with positive linear responses with adaxial epidermis thickness (ADET).

Cabbage cultivation with organic inputs in agroforestry systems may be an alternative for cultivation in the state of Roraima. In this context, the objective of this study was to evaluate the effects of bovine biofertilizer and alley system on the production components of Sooshu hybrid cabbage. The experiment was conducted from August 2019 to July 2020 at the Agrotechnical School of the Federal University of Roraima. The treatments were arranged in randomized blocks, in split plots, with three replicates. The factorial scheme used was 2 × 5, referring to production in systems without and with alleys and five concentrations of bovine biofertilizer (0, 25, 50, 75 and 100% of the 8 L m-2 dose). After 113 days of application of the bovine biofertilizer, the following were evaluated: i) mass of the leaves that form the head; ii) number of outer leaves; iii) mass of outer leaves; iv) transverse and longitudinal diameters and v) yield. The agroforestry system had no influence on cabbage production components. Bovine biofertilizer at concentration of 63.13% promoted higher mass of leaves that form the head and yield of Sooshu hybrid cabbage.

Salinity is one of the key environmental factors that affects the growth and survival of marine organisms including mussels. Five different salinity levels (40, 30, 20, 10 and 5 ppt) were used to test the effect of abrupt salinity change in the survival of hatchery-produced spats of Asian green mussel Perna viridis (Linnaeus, 1758). Spats were stocked with a density of 30 individuals per 6-L tank. Salinity manipulation was conducted after 2 days from the date of stocking. Based on the results, abrupt change and prolonged exposure to lower salinities particularly of 5 and 10 ppt (up to 5 days) are detrimental to P. viridis spats. The critical time for P. viridis spats wherein they could seclude themselves from the persistent lower salinities is 28 hours from its exposure. After which, mortality could be high at about 50% and will continue in the succeeding days if low salinity persists. Critically, no single spat can survive until the 4th day of continuous exposure to very low salinity of 5 ppt. Nevertheless, surviving individuals could still recover if salinity will return to optimum levels. Additionally, spats can readily adjust to abrupt change up to 10 ppt from the optimum salinity level as seen in the high survival in 20 and 40 ppt.

Stimulator of interferon genes (STING) is a cytosolic DNA sensor or directly recognizes bacterial cyclic dinucleotides, which is required for the detection of microbial infection. Extracellular traps (ETs) are known to be part of the antimicrobial defense system. However, the implication of STING in ETs formation during microbial infection remains unknown. Here, we showed that STING contributed to Staphylococcus aureus (S. aureus)-induced ETs formation through the ROS-ERK signaling. STING deficiency exhibited decreased cell-free DNA (cfDNA) level, reduced expression of citrullinated histone H3 (CitH3), and diminished DNA colocalization with CitH3 and myeloperoxidase (MPO). Interestingly, NADPH oxidase-derived reactive oxygen species (ROS) promoted ETs formation, accompanied by increased activation of extracellular signal-regulated kinase 1 and 2 (ERK1/2) in S. aureus-stimulated bone marrow-derived macrophages (BMDMs). Corresponding to less ROS production, decreased ERK1/2 activation was shown in STING-/- BMDMs after S. aureus infection. Importantly, inhibiting the ROS-ERK signal reduced the ETs formation and the differences disappeared between WT and STING-/- BMDMs after S. aureus infection. Moreover, STING-/- BMDMs exhibited significantly increased levels of extracellular bacteria compared to WT BMDMs regardless of phagocytosis. In addition, such differences disappeared after DNase I treatment. DNase I treatment also facilitated pathogen colonization without affecting the inflammatory cells infiltration and pro-inflammatory factors secretion following pulmonary S. aureus infection. Furthermore, STING-/- mice presented decreased levels of cfDNA and CitH3, along with increased bacterial colonization compared to WT mice. Altogether, these findings highlighted that STING promoted ETs formation via the ROS-ERK signal for host defense against S. aureus infection.

Ubiquitination and SUMOylation, which are posttranslational modifications, play prominent roles in regulating both protein expression and function in cells, as well as various cellular signal transduction pathways. Metabolic reprogramming often occurs in various diseases, especially cancer, which has become a new entry point for understanding cancer mechanisms and developing treatment methods. Ubiquitination or SUMOylation of protein substrates determines the fate of modified proteins. Through accurate and timely degradation and stabilization of the substrate, ubiquitination and SUMOylation widely control various crucial pathways and different proteins involved in cancer metabolic reprogramming. An understanding of the regulatory mechanisms of ubiquitination and SUMOylation of cell proteins may help us elucidate the molecular mechanism underlying cancer development and provide an important theory for new treatments. In this review, we summarize the processes of ubiquitination and SUMOylation and discuss how ubiquitination and SUMOylation affect cancer metabolism by regulating the key enzymes in the metabolic pathway, including glucose, lipid and amino acid metabolism, to finally reshape cancer metabolism.

Metal-doped graphitic carbon nitride (MCN) materials have shown great promise as effective photocatalysts for the conversion of acetic acid to carbon dioxide under UV–visible irradiation and are superior to pristine carbon nitride (g-C3N4, CN). In this study, the effects of metal dopants on the physicochemical properties of metal-doped CN samples (Fe-, Cu-, Zn-, FeCu-, FeZn-, and CuZn-doped CN) and their catalytic activity in the photooxidation of acetic acid were investigated and discussed for their correlation, especially on their surface and bulk structures. The materials in the order of highest to lowest photocatalytic activity are FeZn_CN, FeCu_CN, Fe_CN, and Cu_CN (rates of CO2 evolution higher than for CN), followed by Zn_CN, CuZn_CN, and CN (rates of CO2 evolution lower than CN). Although Fe doping resulted in the extension of the light absorption range, incorporation of metals did not significantly alter the crystalline phase, morphology, and specific surface area of the CN materials. However, the extension of light absorption into the visible region on Fe doping did not provide a suitable explanation for the increase in photocatalytic efficiency. To further understand this issue, the materials were analyzed using two complementary techniques, reversed double-beam photoacoustic spectroscopy (RDB-PAS) and electron spin resonance spectroscopy (ESR). The FeZn_CN, with the highest electron trap density between 2.95 and 3.00 eV, afforded the highest rate of CO2 evolution from acetic acid photodecomposition. All Fe-incorporated CN materials and Cu-CN reported herein can be categorized as high activity catalysts according to the rates of CO2 evolution obtained, higher than 0.15 μmol/min−1, or >1.5 times higher than that of pristine CN. Results from this research are suggestive of a correlation between the rate of CO2 evolution via photocatalytic oxidation of acetic acid with the threshold number of free unpaired electrons in CN-based materials and high electron trap density (between 2.95 and 3.00 eV).

Solid-state lithium metal batteries have attracted more and more attention in recent years because of their high safety and energy density, with developments in the new energy industry and energy storage industry. However, solid-state electrolytes are usually symmetric and are not compatible with the cathode and anode at once. In this work, a flexible asymmetric organic-inorganic composite solid-state electrolyte consisting of PI membrane, succinonitrile (SN), LiLaZrTaO(LLZTO), Poly (ethylene glycol) (PEO), and LiTFSI were prepared by solution casting successfully. This lightweight solid electrolyte is stable at a high temperature of 150°C and exhibits a wide electrochemical window of more than 6 V. Furthermore, the high ionic conductivity of the flexible solid electrolyte was 7.3 × 10−7 S/cm. The solid-state batteries assembled with this flexible asymmetric organic-inorganic composite solid electrolyte exhibit excellent performance at ambient temperature. The specific discharge capacity of coin cells using asymmetric organic-inorganic composite solid-state electrolytes was 156.56 mAh/g, 147.25 mAh/g, and 66.55 mAh/g at 0.1, 0.2, and 1C at room temperature. After 100 cycles at 0.2C, the reversible discharging capacity was 96.01 mAh/g, and Coulombic efficiency was 98%. Considering the good performance mentioned above, our designed flexible asymmetric organic-inorganic composite solid electrolyte is appropriate for next-generation solid-state batteries with high cycling stability.
