Feline aortic thromboembolism with and without congestive heart failure did not exhibit hypercoagulability using a novel viscoelastic coagulation monitor
Authors: Moses Ivan A. , Hallowell Theresa C. , Johnson Justine A.
Published: June 2024

OBJECTIVE

To demonstrate hypercoagulability with a benchtop viscoelastic monitor in cats with congestive heart failure (CHF) and/or aortic thromboembolism (ATE) compared to controls.

METHODS

97 cats were enrolled throughout this prospective observational cohort study from September 2022 through October 2023. Cats were grouped by diagnosis of CHF, ATE, ATE plus CHF, or controls. Enrollment required diagnosis of heart disease and no previous antithrombotic therapy. The results of viscoelastic testing with the benchtop viscoelastic coagulation monitor (VCM Vet [VCM]; Entegrion) were compared between groups using factorial analysis of variance.

RESULTS

Cats with heart disease had significantly higher clot times when compared to controls (control: mean, 285.3 [SD, 172.6]; CHF: mean, 391.7 [SD, 106.8]; ATE: mean, 415.9 [SD, 109.2]; and ATE plus CHF: mean, 368.6 [SD, 232.6]). Heart disease cats were noted to have significantly lower 45-minute lysis index values (control: median, 100 [range, 93 to 100]; CHF: median, 99 [range, 89 to 100]; ATE: median, 98 [range, 88 to 100]; and ATE plus CHF: range, 98 [91 to 100]). Age was a covariate to this variable, and when applied to analysis, statistical significance was lost. No significant difference in any other variables were noted.

CLINICAL RELEVANCE

The hypercoagulability of ATE and CHF cats was not detected by the VCM. Further research with other coagulation monitors is required in this population.
Incidence and type of voluntary reported perianesthetic medication errors in community veterinary clinics in Calgary, Canada
Authors: Pinho Renata H. , Tscheng Dorothy , Cheema Jagjit S. , Pang Daniel S. J.
Published: June 2024

OBJECTIVE

To collect medication error (ME) data during the perianesthetic period from small animal clinics.

SAMPLE

6 small animal general practice veterinary clinics.

METHODS

Small animal general practice veterinary clinics were recruited in this prospective observational study, with staff given a presentation on medical errors and instructed on how to submit medication error reports to an online reporting system. Errors were classified according to type and timing.

RESULTS

A total of 2,728 general anesthesia or sedation procedures were performed, with 49 ME reports submitted. One duplicated report of the same error was excluded, resulting in a ME rate of 1.8%. Most reports (69% [33/48]) were near misses. The remaining 31% were MEs that reached the patient but did not cause harm. Wrong dose errors were the most common type (63% [30/48]), of which 80% (24/30) were calculation errors. Premedication/sedation and maintenance were the most reported stages, at 47% (20/43) and 23% (10/43), respectively. None of the MEs reported resulted in an adverse event, with an approximately 2:1 ratio of near-miss to no-harm MEs. The observed patterns of MEs reported, including type and timing, represent a target for further education.

CLINICAL RELEVANCE

These results quantify the ME rate in general practice veterinary clinics, providing an initial benchmark for MEs during the perianesthetic period.
Cooperative Societies as a Sustainable Legislative Aspect of the Establishment of a Dispersed Hotel
Authors: Pavić Lazar , Vizjak Katja
Published: June 2024

Dispersed hotels, characterized by their decentralized accommodation facilities integrated into existing structures of historical or cultural significance, have emerged as a sustainable alternative to traditional centralized hotels. This study explores the role of cooperative societies as a legislative and organizational framework for establishing and managing dispersed hotels. Utilizing a mixed-methods approach, the research analyzes case studies from Europe where cooperative models have successfully facilitated the integration of dispersed hotels into local communities, ensuring economic and cultural sustainability in Slovenia. The findings indicate that cooperative societies enable effective resource sharing, community engagement, and equitable distribution of economic benefits, which are essential for the long-term sustainability of dispersed hotels. Legislative support in the form of favorable policies and financial incentives has been identified as critical in fostering these cooperative initiatives. The study suggests that cooperative societies not only enhance the operational sustainability of dispersed hotels but also contribute to the conservation of cultural heritage and the stimulation of local economies. The results advocate for policymakers to consider cooperative models in tourism development strategies, emphasizing their potential to transform local communities and promote sustainable tourism practices.

Authors: Jastrzębski Marcin
Published: June 2024

This scientific article examines the system of electoral districting in the 2023 Sejm elections and its impact on the principle of equality of representation. The main objectives of the study are to analyse the relationship between the principle of equality of representation and electoral districting in Sejm elections, evaluate the compliance of current constituency boundaries with this principle, and assess the potential consequences of any changes in districting in the 2023 Sejm elections in terms of electoral representation. The research questions guiding this study are as follows: (1) How should constituencies be determined for the 2023 Sejm elections and what legal criteria should be applied in electoral districting? (2) Does the current districting system align with the principle of equality of representation? (3) Are there disparities in the size or demographics of constituencies that could result in unequal representation in the Sejm? (4) What are the potential implications of the current districting system for the representation of different political parties? (5) How do alternative scenarios of districting affect the principle of equality of representation in the context of the 2023 Sejm elections? The research employs an institutional-legal analysis, along with statistical data analysis and simulations, to model alternative districting scenario and evaluate their effects on the principle of equality of representation. The findings of this study contribute to a comprehensive understanding of the implications of districting on the principle of equality of representation in the 2023 Sejm elections. The research emphasises the significance of fair districting for ensuring equal representation and provides valuable recommendations for policymakers.
Political Institutions in Times of AI, and Ethical Aspects of the Digitalization in Politics
Authors: Jafarova Lala Afig
Published: June 2024

As a result of globalization, and modern scientific and technological development, information technologies began to cover an increasing number of areas, including politics. The issue actualizes as we enter the Artificial Intelligence (AI) era. In times of AI, increasing scientific influence on politics was manifested in the development of a new scientific field — Digital Diplomacy. The development of AI and the changes taking place today can transform the political processes, imposing new threats to the political systems and the entire system of international relations. In this context, ethical issues are of particular concern because they can be blurred by the political decisions made by digital/computer program algorithms; that is, giving power to computer programs to make political decisions can destabilize the political system. This issue is particularly sensitive in terms of ensuring justice and protection of state political interests. The presented paper aims to discuss political transformation in the context of the modern digitalization process, the work of political institutions, and digital diplomacy.

Lifetimes of Instability: the Consequences of Excluding Syrian Boys on the Progressive Era US-Mexico Border
Authors: Bavery Ashley Johnson
Published: June 2024

In the first decade of the twentieth century, United States immigration inspectors at the US-Mexico border excluded hundreds of young Syrians, turning many toward unstable lives as unauthorized migrants in North America. Inspectors combined Progressive Era concerns about child labor with orientalist and racist views of migrants from the Ottoman Empire to conclude that unaccompanied young Syrians posed a threat to the American family and workplace and should be sent back across the Atlantic. And while some excluded boys did return to Syria, the majority found ways to enter the United States without authorization. Some sought the help of smugglers and others obtained falsified papers that claimed uncles, brothers, and family friends as their fathers and accompanied them across the border. While these tactics worked, illicit border crossing launched young migrants into an unauthorized life marked by precarity and fear. In fact, oral histories conducted by the author have revealed that young boys who entered the United States without authorization often ended up in unstable professions connected to urban underworlds. Ultimately, this article seeks to demonstrate the ways hardline immigration policies of the early twentieth century targeting young boys set them on paths toward precarity as they navigated lives in the United States.
Impact of Political Ideology on Spending Audiences of Brazilian States
Authors: Scheeffer Fernando , Fabre Valkyrie Vieira
Published: June 2024

Objective: The present study seeks to verify the extent to which affiliation with parties in different locations on the ideological spectrum explains public spending in Brazilian states (2012-2017).
 
Theoretical framework: To achieve the proposed objective, the article in question has a section where the theoretical framework is exposed, consisting of the discussion regarding the classic distinctions between left and right and the relationship with the provision of public policies.
 
Method: Data were collected using the National Treasury Secretariat (STN) databases. Some expenditure functions were chosen which, in principle, would denote ideological divergences between left and right parties and consequently differentiated public spending, namely: public security, social assistance, health, education, urban planning and environmental management. With the database ready, the Chi-square test was carried out to check whether there was an association between ideologies and spending. The Mann-Whitney U test was subsequently applied to compare the median expenditures of the two terms (2012-2014 and 2015-2017). Finally, panel data were used.
 
Results and Discussion: It can be seen that there is no consistent relationship between ideology (E/D) and public spending, that is, left-wing and right-wing parties tend to spend similarly. The exceptions are spending on education and urbanization, which are higher in states led by managers affiliated with left-wing parties, as expected.
 
Implications of the Research: If ideology is a good predictor of political positioning in the legislature, the same cannot be said in the executive and subnational governments. The ideological component here remains in the background and reveals little explanatory power.
 
Originality/Value: Few studies delve into the impact of political ideology on the provision of public policies.
The Impact of Globalization on National Legal Systems
Authors: Uc Dao Tri
Published: June 2024

As a multifaceted and multidimensional phenomenon of the present era, globalization is relevant to and has comprehensive impacts on all aspects of state governance, social administration, and legal systems. All elements that constitute a nation’s legal system interact with the process of globalization and are influenced by it, including legal and academic ideas, legal science, the system of legal regulations and institutions, legal norms, procedures, and structural-legal institutions. In the process of modernization and legal reform under the influence of globalization, the issue goes beyond recognizing and embracing the diversity and differences among legal systems. It involves paying attention to those distinctive factors to proactively integrate the national legal system into the global legal system while preserving the unique characteristics of the national identity. This principle is at the core of the internationalization of a country’s legal system under the impact of globalization.

Recurrence of cyclonic events over the Sakha Republic (Yakutia) in summer months
Authors: Ignatyeva Y. I. , Tananaev N. I.
Published: June 2024

Extratropical cyclones over the Sakha Republic (Yakutia) bring rains and reduce the probability of forest fires, but can cause fast rainflood events caused by heavy precipitation. In this study, recurrence of cyclonic events over the Sakha Republic (Yakutia) in summer months between 1950 and 2022 is considered. Recurrence of cyclonic events was defined as the count of cyclone centers over Yakutia or subregions at a standard time of observations. Extratropical cyclone centers database from University of Manitoba (Canada) based on ERA5 reanalysis was used in this study. Cyclonic weather over the territory of the Sakha Republic (Yakutia) persists for 27.5 days on average. The largest count of cyclonic events is noted in the North-Eastern and North-Western sub-regions, while the smallest is in the Southern and Central sub-regions. Across summer months, cyclones are most active in June in all regions except for the Southern sub-region. Here, increased July cyclonic activity is determined by conditions favorable for atmospheric blocking, limited zonal transport promoting the northward intrusion of southern cyclones. There is no pronounced trend in the frequency of occurrence of cyclones except for some regions and months: Western Area, June, increasing; the Sakha Republic (Yakutia), August, decreasing. An absolute minimum in the number of cyclonic events was established for 2019-2021, which, as we believe, was one of the main reasons for the maximum of forest fire activity in the Sakha Republic (Yakutia) observed in these years, along with the Lena River extremely low flows of 2019. An analysis of the circulation conditions leading to such extremes will make it possible to assess the risk of recurrence of similar situations under the future climate.

Progrese în managementul preeclampsiei: metode noi de screening şi strategii eficiente de prevenţie
Authors: Durdu Cristiana-Elena , Bohîlţea Roxana-Elena
Published: June 2024

Preeclampsia, affecting 5-10% of pregnancies, is a major cause of maternal and fetal morbidity and mortality, cha­rac­te­rized by elevated blood pressure and proteinuria after 20 weeks of gestation. The complications include in­tra­ute­rine growth restriction, eclampsia, placental abruption, and HELLP syndrome. Effective first-trimester screening, re­com­men­ded by international societies, considers maternal risk fac­tors such as the PlGF (placental growth factor) value, the pulsatility index of the uterine arteries, and the mean blood pressure. Advances in soluble biomarkers, especially the sFlt-1/PlGF ratio, offer improved early diagnosis and ma­nage­ment by predicting preeclampsia weeks before the symp­toms appear. Preventive measures – notably, low-dose as­pi­rin – have been validated by the ASPRE study, showing a 62% reduction in preterm preeclampsia risk when ad­mi­nis­tered from 11-14 weeks of gestation. Implementing these scre­ening and prevention strategies nationwide, especially in resource-limited areas, is essential to reduce the incidence and to improve the outcomes for mothers and babies.
Structural transformations of metal-organic cages through tetrazine-alkene reactivity
Authors: Black Martin , Bhattacharyya Soumalya , Argent Stephen , Pilgrim Ben
Published: June 2024

The assembly of metal-organic cages follows rules based on the coordination preferences of metal ions and the geometries of their typically rigid and planar precursor ligands. PdnL2n metal-organic cages are amongst the most structurally diverse with subtle differences in the metal-ligand coordination vectors giving rise to drastically different assemblies, however al-most all rely on the rigidity of aromatic linker groups to avoid the formation of intractable mixtures of structures. Here we exploit the inverse electron-demand Diels-Alder (IEDDA) reaction between tetrazine linker groups and alkene reagents to trigger structural changes induced by post-assembly modification. The structure of the 1,4-dihydropyridazine produced by IEDDA (often an afterthought in click chemistry) is crucial, with the presence of two sp3 centers leading to a greater degree of flexibility and non-planarity in this ligand. This drastically changes the range of accessible metal-ligand coordination vec-tors, triggering an initial Pd4L8 tetrahedral cage to transform into different Pd2L4 lantern cages, with both the extent (thermo-dynamics) and rate (kinetics) of this transformation dependent on the alkene dienophile selected. With cyclopentene, the unsymmetrical 1,4-dihydropyridazine ligands undergo integrative sorting in the solid state, with both head-to-tail orientation selection and enantiomer selection, leading to a single lantern isomer from the 39 possible. This preference is rationalized through entropy, symmetry, and the extent of hydrogen bonding. Subsequent oxidation of the 1,4-dihydropyridazine to the aromatic pyridazine rigidifies the ligands and imparts planarity again. The oxidized ligands can no longer fit in the lantern structure, inducing further structural transformations into Pd4L8 tetrahedral cages and Pd3L6 double-walled triangles. The concept of controllable addition of limited additional flexibility and then its removal through well-defined reactivity we en-visage being of great interest for those interested in structural transformations of any class of supramolecular architecture.
Natural Fragment Bond Orbital Method for Inter-Fragment Bonding Interaction Analysis
Authors: ZHANG Yichi , Sheong Fu Kit , Lin Zhenyang
Published: June 2024

A complex chemical system is often examined based on their fragments, so fragment-based analysis is the key to chemical understanding. We report the natural fragment bond orbital (NFBO) method for inter-fragment bonding interaction analysis, as an extension to the well-known natural bond orbital method. NFBOs together with their corresponding natural fragment hybrid orbitals (NFHOs) allow us to derive local bonding and anti-bonding orbitals among fragments from the delocalized canonical molecular orbitals. In this paper, we provide the algorithm for finding NFBOs and showcase its application to several chemically interesting systems featuring significant inter-fragment bonding interactions. Through these examples, the NFBO method is shown to be a powerful tool for molecules possessing strong inter-fragment bonding interactions.
An Efficient Transmission Power Design for SWIPT Multi-antenna Network Integrated by an Intelligent Reflecting Surface
Authors: Tuan Pham Viet , Hoang Dinh Long , Nguyen Tu Ha , Hoang Trong Duc
Published: June 2024

In this work, intelligent reflecting surface (IRS) is integrated to improve the transmission power in the simultaneous wireless information and power transfer (SWIPT) system with hybrid time-switching (TS) users. The considered scenario includes one base station (BS), one IRS, and multiple TS users, where the BS transmits the information and energy signals to the receivers with IRS assistance. The sum transmission power minimization problem is formulated under the quality-of-service constraints of data rate and energy harvesting amount at the TS users and the equal time-switching periods. The successive convex approximation and alternating optimization methods are exploited to construct efficient algorithms for finding the suboptimal precoding beamforming vectors at the BS and the phase shifts at the IRS elements. Finally, the numerical results show convergence and significant improvement in performance as compared to conventional baseline schemes.

Homalomena occulta, a plant widely used in traditional Vietnamese medicine, was assessed for its antioxidant potential through DPPH radical scavenging and total antioxidant capacity methods. The results showed that Homalomena occulta exhibited significant antioxidant activities with a low IC50 value of 40.27 μg/mL, which is comparable to that of curcumin (38.50 μg/mL). Furthermore, the total antioxidant capacity of the Homalomena occulta extract was determined to be 77.48 ± 2.34 mg GA/g. To investigate the composition of the plant, various compounds including total phenolic, total flavonoid, polysaccharides, and triterpenoids were quantified using colorimetric methods with specific reagents. The content of phenolic compounds, flavonoid compounds, polysaccharides, and triterpenoids in Homalomena occulta was found to be 36.87 ± 0.42 GAE/g, 26.83 ± 0.29 mg QUE/g, 5.06 ± 0.06%, and 52.09 ± 1.77 mg Olenanoic/g, respectively. Notably, this study provides the first-ever report on the polysaccharide and total triterpenoid content of Homalomena occulta.

This study focuses on a 2012 interview between Julian Assange and Sayyid Hasan Nasrallah, leader of the Lebanese resistance organization Hezbollah. The analysis explores how the interview platform, World Tomorrow, provided a space for Nasrallah to articulate his group's narrative regarding their resistance activities against Israeli occupation and their views on the Palestinian struggle. The conversation delves into the historical context of Hezbollah's emergence, the war in Syria, and the rationale behind the U.S. government's efforts to block Hezbollah's media network, Al Manar. This case highlights the tension between freedom of speech and state control of information, particularly when dealing with designated terrorist organizations.The backdrop for the interview is the broader context of the Israeli-Palestinian conflict and the concept of a "Greater Israel" envisioned by some within Israeli governance. The success of Hezbollah's resistance tactics in forcing Israel's withdrawal from South Lebanon in 2000 and their further military resistance during the 2006 invasion solidified their image as a potent force against Israeli occupation. This stands in stark contrast to the portrayal of Hezbollah as a terrorist organization by Western powers. The analysis examines how Al Manar functions as a tool for Hezbollah's resistance efforts, specifically by countering the dominant narrative of Israeli invincibility and promoting a perspective of Palestinian liberation. The study contributes to the understanding of how media platforms can be utilized by non-state actors to challenge established narratives and garner support for their cause in a globalized media environment.
WHICH DETERMINANTS EXPLAIN MUNICIPALITIES' DEBT? THE CASE OF PORTUGUESE MUNICIPALITIES FROM 2014 TO 2017
Authors: Lisboa Inês Margarida Cadima , Carvalho Alexandra Cristina Pinheiro
Published: June 2024

Objective: Municipality sustainability is crucial for promoting the country's wealth and the citizens' well-being. Therefore, understanding municipalities' indebtedness is relevant to avoid situations of severe financial constraints. This work aims to understand the determinants that explain Portuguese municipalities' debt levels (both total and excess of debt), after the introduction of the Regime Financeiro das Autarquias Locais e Entidades Intermunicipais (RFALEI) published in 2013 (Law no. 73/2013).
 
Theoretical Framework: In this work, the indebtedness of Portuguese municipalities is studied, from the perspective of net debt and excess indebtedness in order to give a broader picture of this topic and to be able to characterize the main determinants that explain debt in Portuguese municipalities.
 
Method: Municipalities' debt is measured using not only the net debt ratio (as most of the works) but also the excess of municipalities' indebtedness. Institutional, political, and financial-economic variables are analyzed to explain debt using a linear regression model with fixed effects. The sample includes all Portuguese municipalities for the period from 2014 to 2017.
 
Results and Discussion: Results show that only institutional and financial-economic determinants are relevant to explain municipalities’ indebtedness. Municipalities with less tourism, less State transfers, and with more capital revenues are the ones more indebtedness. Beyond these factors, municipalities with more investments and less tax revenue tend to present more excess debt.
 
Research Implications: The results of this work are useful to a group of users of the information provided by municipalities: By knowing the main reasons that lead to debt, municipal managers can somehow reduce debt; Regulatory entities can create laws to limit debt and citizens know how public money is being managed.
 
Originality/Value: This work analyzed all Portuguese municipalities, during four years, a larger sample than used in previous works. Moreover, institutional, and financial-economic determinants are also used, in addition to political variables, and these determinants show relevance to explain municipalities' debt. Finally, we focus not only on the debt ratio but also on excess of debt which was the main concern of RFALEI.
“I needed the help. They weren’t giving it”: Experiences of young
people in tertiary education on waitlists for mental health services in
Aotearoa
Authors:   , Wilson-Burke Esta
Published: June 2024

Young people seeking support from mental health services in Aotearoa often face long waitlists and significant delays in receiving care. Extended waits have been associated with worsening symptoms and poorer outcomes, with reports of young people feeling forgotten about and uncared for. Previous research examining waitlist experiences has primarily focused on physical health contexts, with limited studies investigating this experience in depth for those awaiting mental health support. This research explored how young people in tertiary education who had previously been on waitlists for mental health services experienced the waiting period and their perspectives on what could make a difference during this time. Informed by interpretivism and underpinned by phenomenology, semi-structured interviews were conducted with 12 tertiary students aged 18-25 who had experienced being on a waitlist for mental health services in the last two years and had since received help. Four key themes were developed through a reflexive thematic analysis of participants’ interviews.

“You’re in limbo, you’re in flux” captured participants’ paradoxical experiences of feeling stuck in a state of limbo while simultaneously being engaged in constant motion, seeking information and contending with worsening symptoms. Participants described the uncertainty and profound sense of powerlessness that marked this time, as their efforts to access care felt futile. “Sort yourself out” encapsulated participants’ central sense of feeling dismissed and ignored by mental health services and actively left to support themselves. The limited support offered during this time, such as helplines, was often inadequate. “I’m looking for an easier way” reflected participants’ desire for a simpler pathway into mental health services.

Participants wanted information and guidance to help them navigate the system, updates during the waiting period, and options for interim support. “If at least someone like cared about you” captured participants’ desire to have their existence, feelings, and experiences recognised and validated while awaiting professional services. Participants wanted acknowledgement and reassurance from staff members and to feel genuinely cared for as individuals. This research suggests that waiting for mental health services is challenging and distressing, but there are small things that can be done to improve the quality of the wait.

Service providers looking to support young people on waitlists may consider the value of communicating information clearly and readily and conveying warmth and compassion during interactions with young people.
Factors Impacting on Clinical Competence of Nursing Student in a Problem based Learning Curriculum during Clinical Learning
Authors: Matlhaba Kholofelo
Published: June 2024

Clinical competence of Nursing student depends on the supervision received during clinical learning. Supervisors in the clinical area plays an important role for Nursing student when developing their clinical competence in a clinical learning phase. During clinical learning, the expectation is that Nursing student should be able to integrate theory and practice when working with patients. This paper aims to account for those factors that affect competence during clinical learning of Nursing student through a Problem Based Learning curriculum. Thus, the paper reflects a section from a study whose objective was to investigate and outline professional nurses’ understandings of the clinical competencies of final-year Nursing student participating in a Problem Based Learning curriculum during clinical training in the North West Province, South Africa. A qualitative, explorative, descriptive and contextual research design was employed in the main study which had a target population of professional nurses in three hospitals in which the Nursing student following a Problem-Based Learning curriculum were placed for clinical learning. The study employed purposive sampling techniques with semi-structure interviews. In this paper, two themes and six subthemes are ported as follows: 1. that there was dysfunctional collaboration between all stakeholders including facilitators and professional nurses and 2. Professional nurses had attitudes towards Problem Based Learning. Clinical placements required meticulous planning and identification of specific theoretical learning which matched the practical learning requirements pertinent to the Nursing student’ training levels. It is therefore concluded that the development of the clinical competence of Nursing student in a Problem Based Learning curriculum is dependent on stakeholder collaboration.

Published: June 2024

Premature Rupture of Membranes (PROM) is a condition where the amniotic membranes rupture before delivery. Under normal circumstances 8-10% of preterm pregnant women will experience PROM. One of the contributors to AKI is the incidence of infection where this infection is caused by PROM. Term pregnant women under normal circumstances 8 – 10% will experience PROM. Preterm PROM occurs in 1% of pregnancies. PROM is more common in multiparous and grand multiparas due to excessive uterine motility, reduced cervical flexibility. The aim of the research was to determine the correlation between parity and the incidence of premature rupture of membranes at UMMI Hospital, Bogor City in 2023. This research used a cross sectional correlation design with medical record data as the data source. The samples were all mothers who gave birth with premature rupture of membranes. The measurement results were analyzed using the Chi Square test. The Chi square statistical test shows a value of p = 0.018 (p < 0.05), so Ha is accepted or Ho is rejected. There was a correlation between parity and the incidence of premature rupture of membranes. Further research can elaborate the trigger variables occurrence of PROM. This data can be used as primary data to obtain more results complete, accurate and valid.

The golden age is the most important period that all children go through. At this time, parents need to optimize their child's growth and development. The nutritional adequacy of toddlers must be monitored to detect abnormalities such as stunting, wasting, obesity and malnutrition. Stunting is a condition in young children where height or body length as measured by Z-score does not correspond to age. In today's digital era, healthcare generates large amounts of data every day. This data is in various forms, including text, numbers, and digital images or videos. Computer vision in health care is a field of artificial intelligence that allows computers to interpret and act on visual data, including monitoring the growth and development of toddlers. Computer vision can be used to analyze data on stunting status of toddlers. The aim of this research was to develop mobile media to be able to screen and monitor stunting in toddlers using computer vision. The type of the research was research and development methods where the function of using this method was for product validation and development, with the dependent indicator being stunting toddlers. The results of this research showed an accuracy of 90.5%. These results showed that the application of computer vision and artificial neural networks to predict stunting anomalies in toddlers could be used and showed good results. It is hoped that in the future this application can be used by the government, midwives and cadres to continuously monitor toddler stunting

Authors: Langarshoev M. R
Published: June 2024

Abstract. We obtain sharp inequalities between the best approximations of analytic in the unit disk functions by algebraic complex polynomials and the moduli of continuity of higher-order derivatives in the Bergman weighted space B2,μ. Based on these inequalities, the exact values of some known n-widths of classes of analytic in the unit disk functions are calculated.
