Abstract
Objective: The objective of the present work was to study the relationship between malnutrition and gross motor development.Methodology: Sample included 6087 infants under 24 months of age, participants of the ENSANUT-ECU study. To evaluate nutritional status we calculated z-scores by sex for body mass index/age (BAZ) and height/age (HAZ). Six gross motor milestones were evaluated: sitting without support, crawling, standing and walking with support, standing and walking without support. Data was analyzed using logistic regression models in R.Results: Independently form age, sex and other socio-economic factors, the achievement of three gross motor milestones was significantly associated to nutritional status: sitting without support, crawling and walking without support. Compared to infants with normal HAZ, the odds of sitting without support was significantly lower among infants at risk of chronic undernutrition (OR, 0.688; 95%CI, 0.496–0.954) or with chronic undernutrition (OR, 0.601; 95%CI, 0.433–0.833). The odds of crawling (OR, 0.730; 95%CI, 0.635–0.860) and walking alone (OR, 0.741; 95%CI, 0.590–0.933) were also significantly lower among infants with chronic undernutrition in comparison to infants with normal HAZ. In general obesity/overweight were not associated with the achievement of gross motor milestones, except for sitting without support. Obese infants showed higher a odds of sitting without assistance in comparison with children with normal BAZ (OR, 1.650; 95%CI, 1.160–2.245).Conclusions: Chronic undernutrition is related to delayed gross motor development. In Ecuador, public health measures are needed to be implemented in order to prevent malnutrition and its detrimental effects on infant development.

Published: March 2022

Abstract
Context: The patch-mosaic model (PMM) is the most common way to describe the landscape in ecological research. Despite this, the gradient model (GM) was proposed as a more accurate representation of the heterogeneity of landscapes; however, little has been explored on the behavior and performance of continuous variables and surface-based metrics from GM under different analytical scenarios.Objectives: We address the question: which landscape metrics, patch-based or surface-based, best explain habitat occupancy patterns of six bird species with different ecological preferences?Methods: We generated detection histories for six bird species in a fragmented Andean landscape from Colombia. We obtain patch-based metrics from a land cover classification and surface-based metrics from the principal polar spectral indices (PPSi) to describe the landscape. Finally, we fitted dynamic occupancy models using variables derived from landscape models and compared their performance using quasi-AIC for each species.Results: We obtained 909 detections for the six selected bird species. We found that PPSi and surface-based metrics were more informative when assessing occupancy patterns for five of the six species studied. In addition, surface-based metrics allowed to detect interspecific differences between species beyond an affinity for a particular cover type.Conclusions: Surface-based metrics can be an alternative for assessing species response to landscape heterogeneity, particularly those that may be more sensitive to fine-scale changes in vegetation cover. However, there is no single “best” model to describe the landscape for all cases. PPSi can be very useful for land cover analysis in landscape ecology studies as an alternative to more popular vegetation indices.

Published: March 2022

Abstract
Background: Structural maintenance of chromosome protein 4 (SMC4) is crucial for chromosome assembly and separation, but its role and mechanism in cardia adenocarcinoma (CA) are unknown.Methods: SMC4 expression levels were initially detected by protein profiling in 20 CA tumour tissues and adjacent normal tissues. The level of SMC4 expression in CA was then evaluated using a Western Blot analysis. Cell proliferation was evaluated by CCK-8 and clone formation test, Scratch and transwell tests were used to investigate cell migration as well as invasion, while through the flow cytometry, we examined the cell apoptosis and progression of the cell cycle. The regulatory effects of the epithelial-mesenchymal transition (EMT) and the Wnt/β-catenin pathway were investigated using Western Blot. A tumorigenesis experiment was used to investigate the influence of SMC4 on tumor development in nude mice.Results: This study showed overexpression of SMC4 in CA tissues and cells. SMC4 knockout significantly caused the inhibition of proliferation, migration, and invasion of CA cells, and inhibited tumor growth in vivo by stimulating the apoptosis and cell cycle arrest in the G0/G1 phase, In addition, down-regulation of SMC4 resulted in decreased expression of Bcl-2, Cyclin D1, CDK4, CDK6, β-catenin, phosphorylated GSK-3β, N-cadherin, and Vimentin, with an increased level of proteins i.e Bax, cleaved-caspase3, and E-cadherin. When SMC4 was overexpressed, these effects were reversed.Conclusion: SMC4 can facilitate the biological progression of CA, suggesting that SMC4 could be a potential therapeutic target for the disease.An earlier version of our study has been presented as a preprint in the following link: https://www.researchsquare.com/article/rs-698892/v1.
Analysis of dialogical relations between speech genres in the text of a french novel
Authors: Lepetiuk Iryna 
Published: March 2022

The object of research of this article is the types of dialogic connections that arise between speech genres inserted into the structure of a literary text, between genres and the text of a novel, between inserted genres and existing texts.
Investigated problem: This study covers several levels. Firstly, the mechanisms of artistic communication, during which the author, with the help of the speech genres present in the text, can give the reader implicit information and activate the latter's participation in the perception of the text of the novel. Secondly, the concept of intertextual relations is expanded, in the case when we consider the inserted speech genre as an independent text. Thirdly, the studied dialogic connections can be extended to other areas of communication: advertising, political, Internet communication, etc.
Main results scientific: The article is the result of the application of the theory of speech genres by M. Bakhtin to the analysis of the structure of a literary text, leading to further development of the concepts of dialogism and intertextuality.
Area of practical implementation of the research results. Intertextuality is one of the main means of creating pragmatic influence in both commercial and political advertising, media and political discourse. Moreover, it can already be argued that with the advent of the latest information technologies, society is moving from intertext to hypertext, which is typical for communication in almost all areas, since they are mediated in one way or another by computer technologies. It is this fact that explains the necessity and necessity of studying the problem of dialogism and intertextuality

Published: March 2022

The objects of this research are: first, to explain some of the causes of high murder rates in South Africa. Second, to refute the labelling of South Africa as the murder capital of the world. Third, exploring some alternative ways to violence resulting in deaths.
The author investigated the following problems: murder done predominately by men, the inefficiency or shortcomings of the police to investigate murder successfully and lack of reports showing a drastic reduction of murders rates, possible due to lenient sanctions given by the courts.
The main results of the research are:
First, South Africa has been incorrectly referred to as the murder capital of the world. A label that scares would be visitors away from the country. This misleading labelling turned out to be factually incorrect according to several reports. Second, there are myriads of reasons why the death rates are very high in South Africa namely: varieties and normalization of violence; socio-economic inequalities; high youth unemployment rates; alcohol and drugs; culture of violence; easy access to firearms; lenient prison sentence; membership of gangsters; ineffective police investigation units; Mental illnesses or psychotic disorders and satanic beliefs.
The area of practical use of the research: is for all citizens, directly or indirectly affected by police and safer communities. Criminal justice students in higher institutions and criminal justice practitioners, government officials, and policymakers.

Published: March 2022

Using the method of statistical modeling of pipeline reliability, the statistical model for forecasting the dependence of the failure parameter of pipelines of main heating networks on the service life and diameter was developed and analyzed. This method includes two techniques. The first allows to obtain predictive dependences of pipeline reliability indicators for systems that include sections of different diameters with different service life periods and actual data on damage over several years. The second increases the correctness of the obtained dependences by optimizing the service life step in the study of damage to heat pipes. As a result of the study, the dependence of the reliability of main pipelines on the service life and diameter was established. The condition and forecast values of the specified indicator of reliability of main heat pipelines, and also dynamics and range of its changes are defined. The average value of the failure rate parameter increases from 0.23 1/km year (diameter 300 mm) to 0.62 1/km year (diameter 800 mm), which is 2.7 times larger than the pipes with the diameter 300 mm. The multiplicity of changes in the value of the parameter of the flow of failures was also established in accordance with the change in the diameter of the pipelines. According to the developed statistical model the dependence for calculation of the forecast of quantity of damages of the main heat pipelines according to their service life, diameter and length is established. This will increase the reliability of heating systems and effectively plan the cost of material, technical and labor resources. The given method can be used to assess the forecast of the reliability of pipelines, respectively, of their diameters for other engineering systems and networks

Background
This survey study investigates surgical patients’ use and perception of digital health technologies in Germany in the pre–COVID-19 era.

Objective
The objective of this study was to relate surgical patients’ characteristics to the use and perception of several digital health technologies.

Methods
In this single-center, cross-sectional survey study in the outpatient department of a university hospital in Germany, 406 patients completed a questionnaire with the following three domains: general information and use of the internet, smartphones, and general digital health aspects. Analyses were stratified by age group and highest education level achieved.

Results
We found significant age-based differences in most of the evaluated aspects. Younger patients were more open to using new technologies in private and medical settings but had more security concerns. Although searching for information on illnesses on the web was common, the overall acceptance of and trust in web-based consultations were rather low, with <50% of patients in each age group reporting acceptance and trust. More people with academic qualifications than without academic qualifications searched for information on the web before visiting physicians (73/121, 60.3% and 100/240, 41.7%, respectively). Patients with academic degrees were also more engaged in health-related information and communication technology use.

Conclusions
These results support the need for eHealth literacy, health literacy, and available digital devices and internet access to support the active, meaningful use of information and communication technologies in health care. Uncertainties and a lack of knowledge exist, especially regarding telemedicine and the use of medical and health apps. This is especially pronounced among older patients and patients with a low education status.
Paternal Leave and Fathers’ Mental Health: A Rapid Literature Review
Authors: Philpott Lloyd Frank , Goodwin John , Saab Mohamad M. 
Published: March 2022

Background: Several countries have introduced paternal leave policies in order to encourage and involve fathers in caregiving. Besides supporting fathers’ involvement, paternal leave may have other consequences such as health improvements. Paternity leave could potentially improve mental health outcomes by reducing stress and anxiety associated with work–family conflict. It can be hypothesized that paternal leave has a positive effect on men’s mental health; however, there have been no recent attempts to review the literature pertaining to such outcomes. Purpose: The aim of this rapid review of the literature was to evaluate the evidence from studies that explored the effect of paternal leave on men’s mental health. Design: Rapid literature review Methods: The review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Electronic databases CINAHL Plus with Full Text, Academic Search Complete, MEDLINE, APA PsycArticles, APA PsycInfo, Social Sciences Full Text (H.W. Wilson), SocINDEX with Full Text, and ERIC were searched for studies that met the inclusion criteria. Findings: A total of 337 records were identified from the electronic database search. Nine studies met the inclusion criteria. The findings suggest that fathers experience mental health benefits as a result of availing of parental leave. The length of leave availed by fathers had an impact on their mental health, with longer duration of paternity leave associated with higher levels of mental well-being. Flexible leave impeded fathers from fully engaging in their paternal role or their employment duties. Conclusion: The mental health benefits of parental leave usually associated with mothers are also extended to fathers, highlighting the importance of this statutory entitlement.

This study investigates informal learning during the Covid-19 pandemic in Indonesia. Distant learning during the Covid 19 pandemic affects all aspects of education, including parents’ roles that switch to be teachers at home. This condition enables new learning patterns in order to offer children learning opportunities in their home. This study employs a qualitative approach with ethnographic design. The data collection techniques used an open observation guide which was examined for its validity using face and content validity. The techniques of analyzing data included data analysis across sites with some analysis components of data collection, reduction and conclusion. The research findings, in the form of description and formulation of learning patterns reveal adaptive ways to deliver effective education for children. In this way, they are prepared for 21st century skills and to face the industrial revolution 4.0 and society 5.0 in these disruptive times. This pandemic situation forms significant roles of parents in educating their children and strengthen-ing them in facing learning problems. Several parents’ roles include educators, facilitators, tutors, motivators, models, and controllers. Their roles can create pleasant learning situation for their children in the current pandemic situation. The multiroles of parents at home are key to keeping a good learning environment with their children. Therefore, parents are the keys to the success of child education during the Covid 19 Pandemic.

Leaf spot disease of oil palm caused by fungus Curvularia sp. is a major disease in Oil Palm Seedlings (Elaeis guineensis Jacq). Implementation of best nursery practices is the key to prevent it. This study aims to determine the antifungal activity of Jengkol peel (Pithecellobium jiringa (Jack) Prain) extract against the fungus Curvularia sp. which is the cause of leaf spot disease in oil palm (Elaeis guineensis Jacq) seedlings. This study was carried out for five months at the Plantation Plant Protection Center (Balai Proteksi Tanaman Perkebunan, BPTP) in Pontianak. Jengkol peel extract was screened for its ability to inhibit Curvularia sp. growth by in vitro technique. The research method used a completely randomized design (CRD) with a single factor, namely the concentration of Jengkol peel extract, P0: as a control (without extract), P1: extract with a concentration of 10%, P2: extract with a concentration of 20%, P3: extract with a concentration of 30%, P4: extract with a concentration of 40%, and P5: extract with a concentration of 50%. Parameters observed were suppression of colony diameter and suppression of colony biomass. The results of the study showed that the administration of Jengkol peel extract in P5 treatment (50% extract concentration) had a major effect on suppressing the diameter of fungal colonies (36.44%) and showed a significant difference between each concentration (p < 0.05), while the P3 treatment (30% extract concentration) was able to suppress colony biomass up to 100%. The use of Jengkol peel (Pithecellobium jiringa (Jack) Prain) extract has potential as bio fungicide based on the effect found on the suppression of growth both from the diameter and biomass of the fungal colony of Curvularia sp.
