A investigação da regeneração natural após manejo florestal em pequena escala é crucial para a compreensão dos impactos que a exploração florestal causa na estrutura e dinâmica da floresta. Neste estudo, foi avaliada a regeneração natural de espécies comerciais exploradas em manejo florestal em pequena escala. Para isso, vinte clareiras de exploração foram caracterizadas de acordo com o tamanho, abertura de dossel e altura da floresta de borda. Em seguida, a regeneração natural foi diagnosticada a partir da identificação de espécies comerciais (altura ≥ 1,3 m) em nove parcelas de 2 x 2 m. A associação entre a abundância e riqueza da regeneração natural foi testada com correlação de Pearson. Foram encontrados 205 indivíduos, pertencentes a 42 espécies e 11 famílias. As espécies que comumente se repetiram foram Protium apiculatum, Protium decandrum e Goupia glabra. A abertura de dossel esteve positivamente associada com a abundância e riqueza de espécies, mas não com a composição de espécies. Portanto, existe uma abundante e diversificada regeneração de espécies comerciais nas clareiras e; a disponibilidade de luz afeta positivamente a quantidade de mudas e espécies da regeneração. No entanto, a composição de espécies nas clareiras não depende da disponibilidade de luz e deve ser manipulada via plantio de enriquecimento.
Palavras-chave: área de clareira; disponibilidade de luz; espécies pioneiras.

Natural regeneration of commercial species in area submitted to small-scale forest management in the middle Amazon

ABSTRACT: The investigation of natural regeneration after small-scale forest management is crucial for understanding the impacts that logging causes on the structure and dynamics of the forest. This study evaluated the natural regeneration of commercial species exploited in small-scale forest management. For this, twenty logging gaps were characterized according to size, canopy opening and forest edge height. Then, natural regeneration was diagnosed from the identification of commercial species (height ≥ 1.3 m) in nine 2 x 2 m plots. The association between the abundance and richness of natural regeneration was tested with Pearson's correlation. A total of 205 individuals were found, belonging to 42 species and 11 families. The species that commonly repeated were Protium apiculatum, Protium decandrum and Goupia glabra. Canopy openness was positively associated with species abundance and richness, but not with species composition. Therefore, there is an abundant and diversified regeneration of commercial species in the gaps and the availability of light positively affects the number of seedlings and species in regeneration. However, species composition in gaps does not depend on light availability and must be manipulated via enrichment planting.
Keywords: gap area; light availability; pioneer species.
Representation of the Influence of Travel Vlog on the Development of Tourism (On the Example of the Authorial Channels on Youtube Video Hosting)
Authors: Bozhkо L. 
Published: July 2023

The purpose of the article. The purpose of the article is to study and demonstrate the influence of travel vlog on the development of tourism using the example of the authorial YouTube video hosting channels.
The methodology. The research methods were content and discourse analysis of travel vlogs from YouTube video hosting, as well as analysis of their structure and target audience.
The results. Ukrainian YouTube travel vlogs are an important leader of public opinion. This category of Internet bloggers has great potential for use in the promotion of Ukraine as a tourist destination, raising the level of awareness of Ukrainians with Ukraine, organizing leisure activities of Ukrainian citizens and foreign guests.
Analyzing the thematic rating of the videos, especially the latest ones, we came to the conclusion that the most relevant topics for the audience of the channels today are trips to different parts of Ukraine, including those in which there were military actions and which were under occupation, as evidenced by the number of views. Some topics are still silenced in the official media and are not widely discussed, despite the fact that these topics are really relevant for society, especially for young people, since the youth audience is the main audience on the Internet platform YouTube. We can express the hope that Ukrainian travel channels will continue to develop in this direction as a high-quality example of new media and will contribute to the formation of a new Ukrainian audiovisual culture.
It is also undeniable that, as part of Travel 2.0, travel blogs make life easier for consumers of travel services in many ways: they help to learn more about the destination and what it can offer the tourist; help to make decisions about certain destinations, add confidence in the choice. reduce the risks and uncertainties associated with travel planning, etc. Therefore, the blogosphere, in our case, YouTube video hosting, can be considered an effective tool for the development of tourism. Bloggers provide feedback and contribute to the development of the country as a modern and popular tourist destination, and their reviews, opinions, comments are sometimes a more reliable than information from the travel service providers themselves.
The scientific novelty. Consideration of tourism through the prism of audiovisual culture.
The practical significance. The materials of this article can be used to develop programs or strategies for the further development of tourism as an integral part of Ukrainian culture.

Amor romántico, fidelidad y happy endings: percepción del reality TV show La isla de las tentaciones por la juventud española
Authors: Blanco-Ruiz Marian , Martínez-Pastor Esther 
Published: July 2023

La versión española del dating show "Temptation Island" ha surgido como un fenómeno de masas entre la población joven española. El objetivo de esta investigación es indagar sobre la opinión de la juventud española sobre las relaciones amorosas mostradas en los dating shows, así como explorar el grado de identificación o rechazo de las historias de amor de estos formatos audiovisuales. Para ello, se diseñó una entrevista guiada por medios telemáticos a 123 jóvenes (74,8% mujeres, 25,2% hombres) de entre 18 y 26 años residentes en España. Los resultados muestran que los y las jóvenes rechazan, en general, los modelos de relaciones amorosas mostrados en "La isla de las tentaciones". Más del 98% muestra una actitud desfavorable hacia los roles de las parejas que compiten, siendo las mujeres las que se posicionan más en contra. Sin embargo, a pesar de demostrar un cierto grado de desmitificación del mito de los celos por amor, identificando ciertos comportamientos como "tóxicos" y, a veces, incluso rechazando explícitamente los roles de género o el amor romántico, se observa en las entrevistas un discurso que refuerza el mito de la fidelidad y los estereotipos de género asociados.

Published: July 2023

In clasical logic, it is possible to combine the uniary negation operator ¬ with any other binary operator in order to generate the other binary operators. In this paper, we introduce the concept of (N∗, O, N, G)-implication derived from non associative structures, overlap function O, grouping function G and two different fuzzy negations N∗ and N are used for the generalization of the implication p → q ≡ ¬ [p ∧ ¬ (¬ p ∨ q)] . We show that (N∗, O, N, G)-implication are fuzzy implication without any restricted conditions. Further, we also study that some properties of (N∗, O, N, G)-implication that are necessary for the development of this paper. The key contribution of this paper is to introduced the concept of circledcircG,N-compositions on (N∗, O, N, G)-implications. If ( N 1 ∗ , O ( 1 ) , N 1 , G ( 1 ) ) - or ( N 2 ∗ , O ( 2 ) , N 2 , G ( 2 ) ) -implications constructed from the tuples ( N 1 ∗ , O ( 1 ) , N 1 , G ( 1 ) ) or ( N 2 ∗ , O ( 2 ) , N 2 , G ( 2 ) ) satisfy a certain property P, we now investigate whether circledcircG,N-composition of ( N 1 ∗ , O ( 1 ) , N 1 , G ( 1 ) ) - and ( N 2 ∗ , O ( 2 ) , N 2 , G ( 2 ) ) -implications satisfies the same property or not. If not, then we attempt to characterise those implications ( N 1 ∗ , O ( 1 ) , N 1 , G ( 1 ) ) -, ( N 2 ∗ , O ( 2 ) , N 2 , G ( 2 ) ) -implications satisfying the property P such that circledcircG,N-composition of ( M 1 ∗ , O ( 1 ) , M 1 , G ( 1 ) ) - and ( M 2 ∗ , O ( 2 ) , M 2 , G ( 2 ) ) -implications also satisfies the same property. Further, we introduced sup-circledcircO-composition of (N∗, O, N, G)-implications constructed from tuples (N∗, O, N, G) . Subsequently, we show that under which condition sup-circledcircO-composition of (N∗, O, N, G)-implications are fuzzy implication. We also study the intersections between families of fuzzy implications, including RO-implications (residual implication), (G, N)-implications, QL-implications, D-implications and (N∗, O, N, G)-implications.
Estimated Impact of Covid-19 on Exchange Rate Risk of Multinational Enterprises Operating in Emerging Markets

Published: July 2023

Multinational enterprises (MNE) operating in emerging countries are exposed to various types of risk. Exchange rate risk is an important and anticipated part of MNE’s total risk exposure, with a variety of tools available to mitigate that risk. In this study, we focus on transaction exposure of cash flows in eight distinctive emerging market currencies and employ the Modified Value-at-Risk (MVaR) model to estimate the maximum one-period loss during an eighteen-month period spanning pre- and post-Covid-19 periods. The predicted losses by MVaR are then compared to the ex-post results, to identify any differences in the pre- and post-Covid-19 periods and to determine the need for adjustments in hedging strategies by MNEs during similar global crises. The motive of this research is to understand the limitations of hedging and what MNEs can do to mitigate transaction exposure risk. The results provide insights on whether MNEs should hedge their currency risk or not. The COVID-19 pandemic did impact all firms globally, so this study is relevant and pertinent as firms plan their post-pandemic growth.

Published: July 2023

The article presents a study of glutathione peroxidase (GPO) isozymes content in ovarian tissue under various physiological and pathological states of cow gonads. The ovarian tissue of 12 cows in different physiological conditions were selected for research, from which homogenates were prepared. The content of isozymes was determined in the supernatant after centrifugation by electrophoresis. After electrophoresis in a 7.5 % polyacrylamide gel and specific staining of the plates according to Lin C. L. and Weydert C. J., 5 bands of catalytically active isozymes of the enzyme (GPO1, GPO2, GPO3, GPO4, and GPO5) were established. They differed in electrophoretic mobility, intensity, and area of band staining. It has been proven that depending on the physiological state of the ovaries, the content of individual isozymes in the gonad tissue changed. In particular, it was found that the content of GPO1 for “late corpus luteum” and “follicular growth” was almost the same, and was in the range of 14.2–15.6 %, and for “early corpus luteum” it was 8.7–10.1 % lower (Р < 0.01). The content of GPO2 was high in “early corpus luteum” (19.9 ± 6.42 %), and in “late corpus luteum” and “follicular growth” it was lower on 11.0–13.2 % (Р < 0.01). The content of GPO3 during “follicular growth” and “early corpus luteum” was within 50.1–51.2 %, and during “late” it decreased on 4.5–5.6 %. According to changes in the physiological state of the ovary in the tissue of “late corpus luteum”, the content of GPO4 was the highest (26.0 ± 2.40 %), and under “follicular growth” and “early corpus luteum” it was lower on 10.2 (Р < 0.05) and 12.9 % (Р < 0.01), respectively. A high content of GPO5 was established in the ovarian tissue of “follicular growth” (10.8 ± 2.00 %), which tended to decrease by 2.8 % and by 4.8 %, respectively, in “early” and “late corpus luteum”. For ovarian tissue with hypofunction, compared to physiological conditions, a probable decrease in the content of the following isozymes was registered: GPO1 by 1.2–11.3 % (Р < 0.01), GPO4 – 6.8–19.7 % (Р < 0 .01) and GPO5 – 2.7–7.5 % (Р < 0.01), while the content of GPO3, on the contrary, increased by 23.6–29.2 % (Р < 0.05–0.01). The study of the dependence of the content of enzyme isozymes on different conditions of the gonad showed that the correlation ratio for the content of GPO isozymes in ovarian tissue under physiological conditions and hypofunction: medium strength was negative for GPO2 and GPO3 (η = 0.473 and 0.530), positive for GPO5 (η = 0.481 ), and strongly positive for GPO1 and GPO4 (η = 0.740 and 0.746).

Authors: Dharma Lindarto  , Ginting Fransiscus 
Published: July 2023

Background: Diabetes is the commonest comorbidity in Coronavirus disease 2019 (COVID-19) patients, and D-dimer level assessment has reliable parameters for assessing and evaluating the prognosis of COVID-19 patients with comorbid. This study aims to compare D-dimer, FPG, and PPG levels between COVID-19 patients with comorbid.
Method: We conducted a retrospective descriptive and analytical study carried out at D-dimer, FPG, and PPG levels of COVID-19 patients with comorbid in a tertiary Hospital in Medan, Indonesia, from April 04, 2020, to November 22, 2020. The data were collected by cheek list, using electronic medical records. The data included age, gender, medical history, comorbidity disease inward, and ICU admission. All these cases of COVID-19 have been confirmed in the laboratory by Real-Time Reverse Transcription Polymerase Chain Reaction (RT-PCR).
Result: From 323 COVID-19 patients with comorbidities, there are significant differences in D-dimer, FPG, and PPG levels between all groups of COVID-19 patients with the comorbid disease (p<0.05), and there is a significant difference in D-dimer, FPG, and PPG level between severity of COVID-19 with comorbidities (p<0.005).
Conclusion: There is a significant difference between D-dimer, FPG, and PPG levels in COVID-19 patients with comorbidities in comorbid type and severity of COVID-19.

IntroductionSmallholder farmers in Sub-Saharan Africa (SSA) are increasingly producing soybean for food, feed, cash, and soil fertility improvement. Yet, the difference between the smallholder farmers’ yield and either the attainable in research fields or the potential from crop models is wide. Reasons for the yield gap include low to nonapplication of appropriate fertilizers and inoculants, late planting, low plant populations, recycling seeds, etc.MethodsHere, we reviewed the literature on the yield gap and the technologies for narrowing it and modelled yields through the right sowing dates and suitable high-yielding varieties in APSIM.Results and DiscussionResults highlighted that between 2010 and 2020 in SSA, soybean production increased; however, it was through an expansion in the cropped area rather than a yield increase per hectare. Also, the actual smallholder farmers’ yield was 3.8, 2.2, and 2.3 times lower than the attainable yield in Malawi, Zambia, and Mozambique, respectively. Through inoculants, soybean yield increased by 23.8%. Coupling this with either 40 kg ha−1 of P or 60 kg ha−1 of K boosted the yields by 89.1% and 26.0%, respectively. Overall, application of 21–30 kg ha-1 of P to soybean in SSA could increase yields by about 48.2%. Furthermore, sowing at the right time increased soybean yield by 300%. Although these technologies enhance soybean yields, they are not fully embraced by smallholder farmers. Hence, refining and bundling them in a digital advisory tool will enhance the availability of the correct information to smallholder farmers at the right time and improve soybean yields per unit area.

IntroductionMeasurement of the nutritive value of feedstuffs with near infrared reflectance spectroscopy (NIRS) laboratory benchtop spectrometers is well-established. The aim of this study was to examine the reliability and accuracy of a handheld low-cost Tellspec NIRS spectrometer for measurement of the nutritive value of oilseed meals.MethodsSamples (n=142) comprising byproduct meals from processing linseed, noug seed, cotton seed, groundnut, rapeseed, soybeans, and sunflower seeds were collected from farms, oil factories, wholesalers, and retail shops in central Ethiopia. Samples were scanned ‘as received’ (UGr) and also following drying and grinding (Gr), and were scanned once, twice, and ten times in a 2x3 factorial experimental design. Laboratory analyses of total nitrogen (TN), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), and in vitro organic matter digestibility (IVOMD) provided reference measurements. Calibration models were developed using a subset of 2/3 of the spectra and validated using the remaining 1/3 of sample spectra.ResultsThe sample form and the number of scans, and their interactions, all significantly affected the accuracy of the calibration models (P&lt;0.001). The most accurate calibrations were with Gr samples scanned 10 times, where the coefficient of determination of both calibration and validation sets (R2cal and R2val) were ≥ 0.90 for most attributes. The respective standard errors of prediction (SEP) (g/kg DM) for Gr, and ‘as received’, samples respectively that were scanned ten times were: TN (3.2 and 4.7), IVOMD (11.7 and 20.1), NDF (26.9 and 43.8), ADF (25.3 and 44.6), and ADL (6.8 and 10.7). Also, the SEP for each attribute was reduced (P&lt;0.05) by drying and grinding the sample before scanning. The ratios of the standard deviation of the calibration samples to the SEP (RPD) g/kg DM were 2.68, 2.30, 3.17, 3.05, and 4.06 for TN, IVOMD, NDF, ADF, and ADL, respectively, for Gr samples scanned ten times. Nevertheless, the SEP of samples scanned ‘as received’ would often be acceptable for routine analyses in the field and market-place under east African circumstances.ConclusionIn conclusion, NIRS calibrations for a portable handheld Tellspec NIRS spectrometer could be developed to measure important nutritional attributes of oilseed cake samples as feeds.
Responsiveness of the electrically stimulated cochlear nerve in patients with a missense variant in ACTG1: preliminary results
Authors: Yuan Yi , Yan Denise , Skidmore Jeffrey , Chapagain Prem , Liu Xuezhong , He Shuman 
Published: July 2023

IntroductionThis preliminary study identified a missense variant in ACTG1 (NM_001614.5) in a family with autosomal dominant non-syndromic hearing loss (ADNSHL). The responsiveness of the electrically-stimulated cochlear nerve (CN) in two implanted participants with this missense change was also evaluated and reported.MethodsGenetic testing was done using a custom capture panel (MiamiOtoGenes) and whole exome sequencing. The responsiveness of the electrically-stimulated CN was evaluated in two members of this family (G1 and G4) using the electrically evoked compound action potential (eCAP). eCAP results from these two participants were compared with those measured three implanted patient populations: children with cochlear nerve deficiency (CND), children with idiopathic hearing loss and normal-sized cochlear nerves (NSCN), and post-lingually deafened adults.ResultsSequencing of ACTG1 identified a missense c.737A&gt;T (p. Gln246Leu) variant in ACTG1 (NM_001614.5) which is most likely the genetic cause of ADNSHL in this family. eCAP results measured in these two participants showed substantial variations.DiscussionThe results indicated the missense c.737A&gt;T (p. Gln246Leu) variant in ACTG1 (NM_001614.5) co-segregated with hearing loss in this family. The responsiveness of the electrically-stimulated CN can vary among patients with the same genetic variants, which suggests the importance of evaluating the functional status of the CN for individual CI patients.
