Published: March 2023

The integration of gender-responsive teaching strategies in public schools remains to be a challenge among educators. This social issue entails more in-depth investigation, especially in primary public education, to promote gender-responsive instruction and increase inclusiveness in education. This study aimed to assess the level of gender mainstreaming efforts of public elementary and secondary schools in the City of Mati, employing the Gender Mainstreaming Evaluation Framework (GMEF). A quantitative design through purposive sampling methods where the respondents are the GAD focal persons was used in this study. The study found out that the Department of Education (DepEd) Schools Division in the City of Mati’s level of gender mainstreaming is still in the Foundation Formation stage (Stage 1). There's a long way to integrate gender into its systems, programs, and services. The study recommends that the agency may craft policies to attain the maximum level of mainstreaming efforts and be modeled and replicated by other agencies in the future.
Involvement of men and women in gleaning macro-invertebrates in Baganga, Davao Oriental, Philippines
Authors: Bantayan Jay Mark
Published: March 2023

Gleaning macro-invertebrates is an essential activity for coastal dwellers, providing food and a source of income. Despite its significance, little is known about its gendered nature in the country. This study aimed to document the gender patterns of men and women involved in gleaning in Davao Oriental. The researcher conducted interviews, field observations, and mapping in two coastal barangays of Baganga, Davao Oriental. Men and women engaged in gathering macro-invertebrates were noticeably different regarding the methods used, presence and absence of target species, and gleaning grounds. Women were found to be more involved in gleaning than men. The accessibility of women to macro-invertebrate resources was influenced by factors such as distance to gleaning   grounds, occurrences of low tide, and good weather conditions. However, accessibility to economically important species limits women due to their lack of implements and fear of waves and even depths. The tools in gleaning used by both men and women in gathering macro-invertebrates were exploitative, which may pose potential destruction to seagrass beds, if unregulated. Men can quickly shift gleaning grounds to look for high-value species, whereas women generally stay at shallow intertidal areas to gather preferably low-valued species. High dependence on gleaning was observed providing income for both men and women in Kinablangan and food source for men and women in San Victor. Though women had higher gleaning efforts than men, gleaning provides them low daily revenues.

Published: March 2023

The clinical efficacy of chemotherapy, as a recognized therapeutic approach for malignant diseases, usually has certain limitations due to its cardiotoxicity (CT) and consequent cardiomyopathy, or even heart failure. CT is defined as any cardiac injury connected with oncology treatment, whether it is chemo-, radio-, targeted or immunotherapy, or cancer by itself, and it represents a great challenge for clinicians in everyday practice. A wide spectrum of factors related to chemotherapy (type of drug, dose during each cycle, cumulative dose, schedule, method of application, combination with other cardiotoxic drugs or association with radiotherapy) and patient characteristics (age, presence of cardiovascular risk factors, previous cardiovascular disease) are the determining factors that influence the frequency of CT. Imaging methods for morphological and functional monitoring of the heart muscle are used for monitoring CT. The quest for diagnostic tools for early CT detection is of great significance. In line with this, the measurement of some cardiac biomarkers has found its place in clinical settings as an early determinant of myocardial injury. Therefore, in this review article, special attention will be paid to certain well-established, as well as certain novel cardiac biomarkers, and their role in recognizing asymptomatic CT, in order to gain deeper insight into their diagnostic utility.

Published: March 2023

Microorganisms used as probiotics should meet elementary safety aspects (non-toxicity, absence of antibiotic resistance genes and translocation) and functional/technological aspects (resistance and survival in the acid gastric environment, adhesiveness, stability, and cell viability). Probiotics with the health claim of being a dietary product or a pharmabiotic (drug category) should be clinically tested, validated, documented, and continuously controlled for quality. Important quality parameters include the identification of declared probiotic strains, the number of viable microorganisms (probiotic bacteria and/or fungi), and microbiological purity (absence of specified pathogenic/opportunistic pathogenic bacteria and fungi, and limitation of total unspecified contaminants such as aerobic bacteria, yeasts, and molds). Due to numerous reports of low-quality commercial probiotics marketed for human use, this review discusses the methods used to test the probiotic microorganism content, safety for the intended use, and proven health benefits of those probiotics whose microbiological quality deviates from the manufacturer's stated content, as well as the maintenance of cell viability, i.e., stability of the probiotic during the shelf life. In addition, the adverse effects of probiotics and the potential hazards to the health of the user are addressed.

Authors: Antunović Marija , Raonić Janja , Vučković Ljiljana
Published: March 2023

Background/Aim: Many studies confirmed strong association between oncogenic genotypes of Human Papillomaviruses (HPVs) and some oropharyngeal and oral squamous cell carcinomas (OSCCs). The aim of this study was to determine the prognostic significance of HPV16 infection in OSCC in population of Montenegro i.e. correlation between HPV16 infection and disease free interval (DFI), disease recurrence and metastasis occurrence. Material and Methods: We examined surgically obtained specimens from 60 patients with OSCC (localized on the lower lip, tongue or/and floor of the mouth) in six years period. Tumor tissue samples were used for histological analysis and HPV16 genome PCR detection (primers for detection of E6 gene). Patients were followed up for the 3 years. Results: HPV16 infection was more commonly detected in females with OSCC (p=0.038), while no correlation between this infection and disease recurrence (p= 0.122) and/or metastasis occurrence (p= 0.934) was found. DFI was not significantly different between patients with or without HPV16 infection (p= 0.427), but DFI was significantly shorter (p= 0.003) in females with oral HPV16 infection compared to male patients with this infection. Conclusions: Counting that HPV16 infection has a negative prognostic significance in OSCC, the HPV immunization program against genital HPV infection, would also have a positive impact on the frequency of HPV-mediated OSCC in Montenegrin population.

Background/Aim: Dentist-technician communication is crucial for a successful working relationship in the healthcare setting that contributes to positive health outcomes. However, the interruption of the dentist and the technician communication can harm the dental care procedure. Besides, mistakes in dental laboratories can be both expensive and time-consuming. Materials and Methods: This research project focused on paper-based communication in the dental laboratory setting and its impact on the quality of prosthesis of zirconium crowns. The study's findings suggested that ineffective communication between technicians and dentists resulted in poor quality of zirconium crowns. The study adopted quantitative analysis, which entails a purposive non-probabilistic sampling of dentists targeted located in Texas. Statistical measurements such as Pearson's correlation employed in determining the association between the independent and dependent variables. Results: The research results suggest a significant positive correlation between inter-professional communication in the dental care setting and prosthetic treatment quality. The results also underscore the effectiveness of prep guides in improving the communication between the technicians and the dentist. Conclusions: The researchers conclude that adherence to prep guides contributes to the quality of zirconium crowns and productive communication among dentists and technicians.
On ultimate strength of an inland waterway barge
Authors: Ilić Nemanja , Momčilović Nikola
Published: March 2023

Due to the sudden nature of hull girder collapse caused by extreme loadings, the ultimate strength of ships, i.e., ultimate capacity, has to be evaluated. Ultimate strength analysis procedures have already been provided within the rules of the classification societies for sea-going ships. However, rules for inland vessels are not fully addressing the issue. In addition, literature data on the ultimate strength of inland vessels are almost negligible, which is alarming, considering the frequency of grounding and overloading events in inland navigation. Moreover, inland vessels' structural elements are prone to buckling due to their slender plates. In order to evaluate ultimate strength, an inland waterway (IW) barge is chosen for progressive collapse analysis (PCA) employment. PCA has demonstrated that the buckling collapse of structural elements vastly governs a vessel's ultimate capacity. Results show the extent of the safety zone between the actual loss of the ultimate capacity and the linear-elastic behavior of the structure.
Air traffic modernization and control: ADS-B system implementation update 2022: A review
Authors: Kožović Dejan , Đurđević Dragan , Dinulović Mirko , Milić Saša , Rašuo Boško
Published: March 2023

Automatic Dependent Surveillance-Broadcast (ADS-B) is a multiparameter surveillance system designed to improve key segments of air traffic: enabling real-time surveillance, raising safety and efficiency levels, and improving flight information and weather services. ADS-B consists of two subsystems, ADS-B Out and ADS-B In. Although only a complete system, ADS-B In/Out provides numerous benefits (additional situational awareness, more efficient oceanic routing, etc.) FAA and EASA only require ADS-B Out (by January and June 2020, respectively), whereby ADS-B In remains optional. Because of its many advantages, ADS-B In/Out will be popular, but there are some weaknesses, which are primarily related to its cyber vulnerabilities due to insufficient authentication and encryption in the applied protocol. In this paper, an overview of the ADS-B system is presented as an aid to understanding the security problems and the different ways of potential attack. In addition, this review deals with the current state of ADS-B deployment and its future perspective and challenges.
Creativity and leadership
Authors: Vukadinović Maja
Published: March 2023

This paper analyses the relationship between leadership and creativity by comparing the characteristics of a successful leader and a creative person and finding out how they may be linked. It is hypothesized that creativity represents one of the most important traits a successful leader should have. It is presumed that creativity unites originality, openness, sensibility, flexibility, fluency of ideas, fantasy, tolerance of uncertainty, creative generalization, and creative differentiation and can be recognized through them. This qualitative study is based on analysis and comparison of the results of different studies in leadership and creativity. Our analysis has shown that creativity is not listed among the key characteristics of a leader (e.g., intelligence, self-confidence, decisiveness and integrity). It should, however, be recognized as such. The main contribution of this study lies in acknowledging creativity as a component sine qua non of successful leadership. The main implication of our results is related to the thesis that encouragement, development and implementation of creativity in every part of the leadership process should result in greater success in every business domain where leadership is necessary. The main recommendation from our results is to encourage and enhance creativity in every business domain, especially leadership. Moreover, empirical exploration regarding the relationship between creativity attributes and a successful leader's characteristics is recommended.

O fetiche como estrutura, imagem e performance no Teatro de Nelson Rodrigues
Authors: Carvalho Isadora Grevan de
Published: March 2023

O teatro de Nelson Rodrigues, por sua complexidade e gama de contradições, constitui um terreno fértil para o estudo da exploração de performance, do corpo e da imagem como um lugar de conhecimento, especialmente em suas dimensões fetichistas. Este livro tem como proposta analisar as criações do dramaturgo, investigando a estrutura, a imagem e a performance do fetiche e de que maneira se apresentam em todas as suas peças. Com esse intuito, a autora examina oito roteiros do autor, entre eles, Os sete gatinhos, Toda nudez será castigada, O beijo no asfalto e Boca de ouro. A perspectiva de fetiche em Rodrigues, apresentada no livro, dialoga diretamente com a análise estrutural de Roberto DaMatta, além de ser enriquecida por interpretações psicanalíticas e marxistas e por outras fundamentações teóricas. A leitura possibilita perceber como o recurso do fetiche inclui Nelson Rodrigues em uma linhagem de autores como Machado de Assis, Lima Barreto e Clarice Lispector, que desconstruíram discursos de gênero e raciais sobre a imaginada identidade brasileira.
Computational modeling of cambium activity provides a regulatory framework for simulating radial plant growth

Published: March 2023

Precise organization of growing structures is a fundamental process in developmental biology. In plants, radial growth is mediated by the cambium, a stem cell niche continuously producing wood (xylem) and bast (phloem) in a strictly bidirectional manner. While this process contributes large parts to terrestrial biomass, cambium dynamics eludes direct experimental access due to obstacles in live-cell imaging. Here, we present a cell-based computational model visualizing cambium activity and integrating the function of central cambium regulators. Performing iterative comparisons of plant and model anatomies, we conclude that the receptor-like kinase PXY and its ligand CLE41 are part of a minimal framework sufficient for instructing tissue organization. By integrating tissue-specific cell wall stiffness values, we moreover probe the influence of physical constraints on tissue geometry. Our model highlights the role of intercellular communication within the cambium and shows that a limited number of factors are sufficient to create radial growth by bidirectional tissue production.
An optimal regulation of fluxes dictates microbial growth in and out of steady state
Authors: Chure Griffin , Cremer Jonas
Published: March 2023

Effective coordination of cellular processes is critical to ensure the competitive growth of microbial organisms. Pivotal to this coordination is the appropriate partitioning of cellular resources between protein synthesis via translation and the metabolism needed to sustain it. Here, we extend a low-dimensional allocation model to describe the dynamic regulation of this resource partitioning. At the core of this regulation is the optimal coordination of metabolic and translational fluxes, mechanistically achieved via the perception of charged- and uncharged-tRNA turnover. An extensive comparison with ≈ 60 data sets fromEscherichia coliestablishes this regulatory mechanism’s biological veracity and demonstrates that a remarkably wide range of growth phenomena in and out of steady state can be predicted with quantitative accuracy. This predictive power, achieved with only a few biological parameters, cements the preeminent importance of optimal flux regulation across conditions and establishes low-dimensional allocation models as an ideal physiological framework to interrogate the dynamics of growth, competition, and adaptation in complex and ever-changing environments.

Authors: Maw Theingi , Leshan Jin , Aung Han Phyo
Published: March 2023

Good Agricultural Practices (GAP) in Myanmar has not yet successfully implemented all around the country, but some farmers and large farm owners now start adopting GAP for fruits production. Data were collected from a total of 105 respondents by suing semi structured questionnaires.

This study revealed that muskmelon farmers’ understanding and awareness on GAP was at a good level but the adoption rate on GAP was still weak. The highest adoption rate was found in the group that followed 10 to 13 out of the 16 recommended guidelines, while the moderate adoption rate was observed in the group that followed 6 to 9 guidelines. The least adoption rate was observed in the group that only followed 3 to 5 guidelines. The adoption of recommended GAP guidelines on muskmelon production was observed positively related with education level of the respondents, farm size, market condition, and extension services for GAP. The difficulty of some GAP guidelines and market condition for GAP products influenced farmers’ perception on the adoption of GAP and the change of farmers’ GAP understanding in the study area. This study also highlight that highly adopting group and moderately adopting group got higher price than less adopting group.

New Emphasis of School Assessment in a Changing World
Authors: Altan Mustafa Zülküf
Published: March 2023

The world after COVID-19 is unlikely to return to the world as it was before. This crisis is alarming since it has several new, unfamiliar and unprecedented features for all areas and sectors. Historically, pandemics have forced humans to break with the past and imagine and create a new one. This one is no different. Now the world today must be more inclusive, resilient, flexible and sustainable.

This paper argues that the pandemic has created a unique opportunity for educational changes that have been proposed before COVID-19 but were never fully understood or implemented mainly focusing on the ever-neglected part of learning and teaching, assessment. Now is the time to rethink what we understand from assessment, redesign how students are assessed and reflect on why we conduct assessments. The ultimate goal of the assessment should aim to prepare individuals to the real world and unexpected problems they will face now and in future. Therefore, the paper proposes that we need more performance based, alternative type of assessment which honor diversity, individual differences and prepare individuals to the real world.

Effects of aqueous seed extracts of Sphenostylis stenocarpa on the reproductive indices of male rats were investigated. A total of 104 adult rats were used for the experiment, and were divided into 4 groups (group A – D) and replicated in triplicate. Group A served as the normal control, while groups B, C and D received three graded doses (800mg/kg, 1200mg/kg and 1600mg/kg) of the extracts, respectively, by oral intubation. The gonad characteristics, sperm parameters and hormonal analyses of the male rats were determined using standard procedures. These were ascertained prior to the commencement of treatment, and on weekly basis. Data were analyzed statistically using SPSS and R software at 95% confidence interval. An overall dose and time dependent showed significant differences in the mean weekly gonad characteristics of the male rats in the treatment groups when compared with the control. There was a significant reduction (p < 0.05) in the body weights of the male rats, but a significant increase (P < 0.05) in the testes weights, gonad somatic index, sperm count and sperm motility in the rats. The gonadal hormone testosterone, responded to the plant extracts, while follicle-stimulating and luteinizing hormones were largely undetected. There were significant increases in the testosterone levels of all the treated rats. Conclusively, aqueous seed extracts of Sphenostylis stenocarpa seems to possess ability to enhance reproductive health in male rats.

Result of ultimate analysis showed oxygen (41.33%,14.06%), nitrogen (3.23%,1.48%), carbon (36.50%,29.67%) and PH value(6.25, 8.47) for food waste and cow dung respectively. The quantity of biogas generated in the different digesters (B1-B9) was 1341.2, 1668, 1784.5, 1945.2, 1941.7, 2159.2, 2328.1 and 2428.5m3/day respectively. Analysis of Covariance (ANCOVA) used to model the biogas production volume showed that there was significant contributions in predicting the volume of biogas produced with F (9,611) = 2684.28 and p-value <0.0001. The effect of potash on biogas production revealed that there was an increase in the quantity of gas generated by the substrates with increase in quantity of potash added. Digester B1 with the lowest quantity of potash, generated 1341.2m3/day of biogas while Digester B9 with the highest quantity of potash, generated 2428.5m3/day of biogas in 90days. The flame test showed that the biogas burned with a blue flame. The findings revealed that biogas can be generated from co-digestion of food waste, potash and cow dung. Thus, potash could have helped to boost the biogas production. More studies should be done on how local organic materials can be useful for the production of more biogas.

Model-Based Operative Performance Expectations for Quantifying Competency in General Surgery
Authors: Krumm Andrew E. , Marcotte Kayla , George Brian C.
Published: March 2023

Importance

Understanding how to translate workplace-based assessment (WBA) ratings into metrics that communicate the ability of a surgeon to perform a procedure would represent a critical advancement in graduate medical education.

Objective

To evaluate the association between past and future performance in a comprehensive assessment system for the purpose of assessing point-in-time competence among general surgery trainees.

Design, Setting, and Participants

This case series included WBA ratings from September 2015 to September 2021 from the WBA system of the Society for Improving Medical Professional Learning (SIMPL) for all general surgery residents who were provided a rating following an operative performance across 70 programs in the US. The study included ratings for 2605 trainees from 1884 attending surgeon raters. Analyses were conducted between September 2021 and December 2021 using bayesian generalized linear mixed-effects models and marginal predicted probabilities.

Exposures

Longitudinal SIMPL ratings.

Main Outcomes and Measures

Performance expectations for 193 unique general surgery procedures based on an individual trainee’s prior successful ratings for a procedure, clinical year of training, and month of the academic year.

Results

Using 63 248 SIMPL ratings, the association between prior and future performance was positive (β, 0.13; 95% credible interval [CrI], 0.12-0.15). The largest source of variation was postgraduate year (α, 3.15; 95% CrI, 1.66-6.03), with rater (α, 1.69; 95% CrI, 1.60-1.78), procedure (α, 1.35; 95% CrI, 1.22-1.51), case complexity (α, 1.30; 95% CrI, 0.42-3.66), and trainee (α, 0.99; 95% CrI, 0.94-1.04) accounting for significant variation in practice ready ratings. After marginalizing overcomplexity and trainee and holding rater constant, mean predicted probabilities had strong overall discrimination (area under the receiver operating characteristic curve, 0.81) and were well calibrated.

Conclusions and Relevance

In this study, prior performance was associated with future performance. This association, combined with an overall modeling strategy that accounted for various facets of an assessment task, may offer a strategy for quantifying competence as performance expectations.

Hepatocellular carcinoma (HCC) is the third deadliest and sixth most common cancer in the world. Histone‐lysine N‐methyltransferase EHMT2 (also known as G9a) is a histone methyltransferase frequently overexpressed in many cancer types, including HCC. We showed that Myc‐driven liver tumours have a unique H3K9 methylation pattern with corresponding G9a overexpression. This phenomenon of increased G9a was further observed in our c‐Myc‐positive HCC patient‐derived xenografts. More importantly, we showed that HCC patients with higher c‐Myc and G9a expression levels portend a poorer survival with lower median survival months. We demonstrated that c‐Myc interacts with G9a in HCC and cooperates to regulate c‐Myc‐dependent gene repression. In addition, G9a stabilises c‐Myc to promote cancer development, contributing to the growth and invasive capacity in HCC. Furthermore, combination therapy between G9a and synthetic‐lethal target of c‐Myc, CDK9, demonstrates strong efficacy in patient‐derived avatars of Myc‐driven HCC. Our work suggests that targeting G9a could prove to be a potential therapeutic avenue for Myc‐driven liver cancer. This will increase our understanding of the underlying epigenetic mechanisms of aggressive tumour initiation and lead to improved therapeutic and diagnostic options for Myc‐driven hepatic tumours.

Infertility affects 10–15% of couples, with half attributed to male factors. An improved understanding of the cell‐type‐specific dysfunction contributing to male infertility is needed to improve available therapies; however, human testicular tissues are difficult to obtain for research purposes. To overcome this, researchers have begun to use human induced pluripotent stem cells (hiPSCs) to generate various testis‐specific cell types in vitro. Peritubular myoid cells (PTMs) are one such testicular cell type that serves a critical role in the human testis niche but, to date, have not been derived from hiPSCs. This study set forth to generate a molecular‐based differentiation method for deriving PTMs from hiPSCs, mirroring in vivo patterning factors. Whole transcriptome profiling and quantitative polymerase chain reaction (qPCR) show that this differentiation method is sufficient to derive cells with PTM‐like transcriptomes, including upregulation of hallmark PTM functional genes, secreted growth and matrix factors, smooth muscle, integrins, receptors, and antioxidants. Hierarchical clustering shows that they acquire transcriptomes similar to primary isolated PTMs, and immunostaining shows the acquisition of a smooth muscle phenotype. Overall, these hiPSC‐PTMs will allow in vitro study of patient‐specific PTM development and function in spermatogenesis and infertility.

Surface reconstruction (SRC) is a common phenomenon and a promotion manner for Ni/Co‐based precatalysts during the water splitting process. However, the catalytic surface reconstruction will in turn complicate the streamlined prediction and modeling on the catalytic activity. Hence, the rational design of anti‐SRC catalysts is highly desirable, but challengeable. In this article, a series of affordable bimetal‐incorporated black phosphorene (BP) catalysts are constructed by an in situ electro‐exfoliation/insertion method for anti‐SRC water electrolysis. It is found that the bimetals (e.g., NiFe, NiPd) are of cationic and covalent incorporation with electron‐deficient state in few‐layer BP. The optimized bimetal‐BP structures present excellent and stable catalytic performances with low overpotentials in hydrogen evolution (HER, 53 mV, NiPd‐BP) and oxygen evolution (OER, 268 mV, NiFe‐BP) reactions at 10 mA cm−2 in 1 m KOH. The anti‐SRC behaviors are elucidated by in situ Raman studies during HER/OER, probably due to the balanced electron transfer pathway on Ni sites. This research opens interesting possibilities for designing the anti‐SRC catalysts for efficient hydrogen production and authentic structure‐activity understandings.

This work reports, for the first time, on radiation resistance of state‐of‐the‐art multicomponent Cs0.04Rb0.04(FA0.65MA0.35)0.92Pb(I0.85Br0.14Cl0.01)3 perovskite photodiodes, tested under high‐intensity pulsed 170 keV proton irradiation with fluence up to 1013 protons cm−2. The studied photodiodes demonstrate record radiation resistance among reported analogous optoelectronic devices. Specifically, it is shown that the proton irradiation with the fluence of 2 × 1012 protons cm−2 even leads to a slight improvement in the photodiode parameters. Nonetheless, a large fluence of 1013 protons cm−2 deteriorates photodiode parameters on average by only 25% with respect to that of the as‐prepared devices. The revealed high‐performance and advanced radiation hardness demonstrate the huge application potential of lightweight and low‐cost solution‐processed perovskite optoelectronic devices in sensing and communication networks operating under harsh space conditions.
