Published: March 2024

Current technological developments provide convenience to the community, one of which is in debt through online loan applications. However, this has led to a change in the behavior of people who like to make loans without thinking about the risks involved. This study aims to describe risk-taking behavior in peer-to-peer lending fintech users. This type of research uses descriptive quantitative methods. The sample used in this study amounted to 160 subjects of peer-to-peer lending fintech users. Accidental sampling techniques were used in this study. The method used is a descriptive analysis method and data collection using a risktaking behavior scale with a reliability coefficient value of 0.923 with a total item of 25 and is declared valid in each variable. Based on analysis through research data software tools on the description of risktaking behavior in peer-to-peer lending / p2p fintech users, it was concluded that peer-to-peer lending / p2p fintech users were in the low risktaking behavior category of 60.6%, medium criteria of 35%, and high criteria of 4.4%. This means that the risk-taking behavior raised by the subjects of peer-to-peer lending fintech users in this study is quite low whereas behavior that contains risk leads individuals to the negative possibility they will receive is low.

Abstract
Milk is an ancient, fundamental mammalian adaptation that provides nutrition and biochemical communication to offspring. Microbiomes have been detected in milk of all species studied to date. In this review, we discuss: (a) routes by which microbes may enter milk; (b) evidence for proposed milk microbiome adaptive functions; (c) variation in milk microbiomes across mammals; and (d) future research directions, including suggestions for how to address outstanding questions on the viability and functionality of milk microbiomes. Milk microbes may be sourced from the maternal gastrointestinal tract, oral, skin, and mammary gland microbiomes and from neonatal oral and skin microbiomes. Given the variety of microbial sources, stochastic processes strongly influence milk microbiome assembly, but milk microbiomes appear to be influenced by maternal evolutionary history, diet, environment, and milk nutrients. Milk microbes have been proposed to colonize the neonatal intestinal tract and produce gene and metabolic products that influence physiology, metabolism, and immune system development. Limited epidemiological data indicate that early-life exposure to milk microbes can result in positive, long-term health outcomes. Milk microbiomes can be modified by dietary changes including providing the mother with probiotics and prebiotics. Milk replacers (i.e. infant formula) may benefit from supplementation with probiotics and prebiotics, but data are lacking on probiotics’ usefulness, and supplementation should be evidence based. Overall, milk microbiome literature outside of human and model systems is scarce. We highlight the need for mechanistic studies in model species paired with comparative studies across mammals to further our understanding of mammalian milk microbiome evolution. A broader study of milk microbiomes has the potential to inform animal care with relevance to ex situ endangered species.

Lay summary
Milk is an ancient adaptation that supports the growth and development of mammalian neonates and infants. Beyond its fundamental nutritional function, milk influences all aspects of neonatal development, especially immune function. All kinds of milks so far studied have contained a milk microbiome. In this review, we focus on what is known about the collection of bacterial members found in milk microbiomes. Milk microbiomes include members sourced from maternal and infant microbiomes and they appear to be influenced by maternal evolutionary history, diet, milk nutrients, and environment, as well as by random chance. Once a neonate begins nursing, microbes from milk colonize their gut and produce byproducts that influence their physiology, metabolism, and immune development. Empirical data on milk microbiomes outside of humans and model systems are sparse. Greater study of milk microbiomes across mammals will expand our understanding of mammalian evolution and improve the health of animals under human care.

Abstract
Although numerous studies have demonstrated the impact of microbiome manipulation on human health, research on the microbiome’s influence on female health remains relatively limited despite substantial disease burden. In light of this, we present a selected review of clinical trials and preclinical studies targeting both the vaginal and gut microbiomes for the prevention or treatment of various gynecologic conditions. Specifically, we explore studies that leverage microbiota transplants, probiotics, prebiotics, diet modifications, and engineered microbial strains. A healthy vaginal microbiome for females of reproductive age consists of lactic acid-producing bacteria predominantly of the Lactobacillus genus, which serves as a protective barrier against pathogens and maintains a balanced ecosystem. The gut microbiota’s production of short-chain fatty acids, metabolism of primary bile acids, and modulation of sex steroid levels have significant implications for the interplay between host and microbes throughout the body, ultimately impacting reproductive health. By harnessing interventions that modulate both the vaginal and gut microbiomes, it becomes possible to not only maintain homeostasis but also mitigate pathological conditions. While the field is still working toward making broad clinical recommendations, the current studies demonstrate that manipulating the microbiome holds great potential for addressing diverse gynecologic conditions.

Lay summary
Manipulating the microbiome has recently entered popular culture, with various diets thought to aid the microbes that live within us. These microbes live in different locations of our body and accordingly help us digest food, modulate our immune system, and influence reproductive health. The role of the microbes living in and influencing the female reproductive tract remains understudied despite known roles in common conditions such as vulvovaginal candidiasis (affecting 75% of females in their lifetime), bacterial vaginosis (25% of females in their lifetime), cervical HPV infection (80% of females in their lifetime), endometriosis (6–10% of females of reproductive age), and polycystic ovary syndrome (10–12% of females of reproductive age). Here, we review four different approaches used to manipulate the female reproductive tract and gastrointestinal system microbiomes: microbiota transplants, probiotics, prebiotics, and dietary interventions, and the use of engineered microbial strains. In doing so, we aim to stimulate discussion on new ways to understand and treat female reproductive health conditions.

Published: March 2024

BACKGROUND AND OBJECTIVE
In Canada and the United States, ∼1 in 5 children live in poverty, contributing to poor health outcomes. Families with children with chronic illness may experience additional financial stress related to hospitalization. This study aimed to capture experiences of financial needs and supports among caregivers with a child admitted to a tertiary care pediatric hospital to inform hospital-based financial services to reduce financial stress in families.

METHODS
We recruited caregivers of children admitted to the general inpatient ward of an academic pediatric center using purposive sampling with no exclusion criteria. Individual, semistructured, in-depth interviews with participants were conducted. Data collected included socio-demographics, financial needs, and experiences with financial supports. Interviews were audio-recorded, transcribed verbatim, coded, and analyzed on NVivo software using a modified-grounded theory approach and summative content analysis.

RESULTS
Fifteen caregivers of diverse backgrounds were interviewed, including non-English speakers (n = 4). Three themes and associated subthemes (in parentheses) were identified: (1) financial stress expressed by participants (acute admission-related and chronic financial stress), (2) challenges associated with accessing and utilizing financial supports (caregiver factors, systemic hospital factors, and systemic government factors), and (3) ideas for financial services at the pediatric hospital (services that will provide acute- and chronic financial assistance including education about financial supports and benefits).

CONCLUSIONS
Our study highlighted acute and chronic financial needs as well as challenges in accessing financial support. Participants were interested in the healthcare system gaining a comprehensive understanding of their financial circumstances and accessing financial services in a hospital setting.

Authors: Kukhar Viktor , Bondarenko Andrii 
Published: March 2024

The purpose was to develop the concept of training students - mechanical engineers in the variable formatting of design documents in accordance with national and international standards and to create a set of educational and methodological materials for its implementation.
The concept envisages the development and implementation of two simultaneously taught courses covering Ukrainian and international requirements for the development and execution of design documents. It is the simultaneous teaching of these courses that makes it possible to acquire the relevant knowledge and skills and to have a unique opportunity to compare different standardisation systems for the same type of design documents in accordance with different stages of the machine life cycle.
The didactic foundations of the pedagogical process and modern principles of organising the learning process have been applied to involve the higher education seekers in mastering professional experience in the field of mechanical engineering and creating positive changes in the formation and development of the individual.
New courses have been created and teaching materials have been prepared for mechanical engineering students to study national and international regulatory frameworks and master the practical skills of their use in future professional activities related to the formatting of design documents.
The work applies a systematic approach that combines elements of the pedagogical system in conjunction with the integrity of the evolutionary development of the applicant, taking into account the dynamic state of development of the modern engineering industry at the national and international levels.
Acquiring relevant knowledge and skills by higher education seekers in design documents following national and international standards ensures an increase in their professional status and competitiveness in the Ukrainian labor market and accelerates the adaptation of Ukrainian specialists to the current conditions of globalization in mechanical engineering
Investigation of drill string dynamics using probabilistic methods
Authors: Svitlytskyi Viktor , Iagodovskyi Sergii , Boshkova Iryna 
Published: March 2024

The object of research is a drill string. The work is directed to the study of the drill string dynamics and its influence on the rock, which is drilled using probabilistic methods.
It is shown that the nature of the vibrations of the top of the drill string and the downhole signals are different and have a stationary random character. It is proved that the process at the output of the drill string, taking into account random disturbances, is narrow-band (quasi-harmonic) or close to it. It is found that the energy composition of the spectrum sections and the appearance of resonance peaks and their displacement is directly determined by the physical and mechanical properties of the rocks being drilled, as one of the factors that determines the vibration state of the drill string. Graphs of the spectral density of the power of pitting vibrations are given, showing their amplification at frequencies of 30–40 Hz as the hardness of the rocks being drilled increases. The maximum of the power density bending curve shifts towards low frequencies. There is a «mutual convergence» of the maxima of the power spectral density of the oscillations of the top and bottom of the drill string. It is shown that an important feature of drill string vibrations in the process of drilling with ball bits is that the intensity of vibrations of the top of the drill string passes with frequencies close to low frequencies, and the vibrations of the bottom of the string – to high frequencies.
It is determined that the process at the output of the drill string, taking into account random disturbances, is narrow-band (quasi-harmonic) or close to it. As a result, the assumption of a narrow band at the output of the system, which is the basis of theoretical research, is justified. It is proven that the drill string, as a system with liquid filling under pressure, is more stable compared to a hollow structure. The washing liquid, in this case, plays the role of a dynamic absorber.

Published: March 2024

The object of research is an automated system for controlling the bending mechanisms of the folding-gluing line for cardboard packaging products. In the work, the ways of optimization and the development of an automated control system for the bending mechanisms of the folding and gluing line, which makes it possible to fold various structures and standard sizes of cardboard boxes using modern automation tools based on programmable logic controllers, were carried out in the work.
A mathematical model has been proposed to describe operations on the folding-gluing line. Based on the model, a methodology has been developed for calculating the parameters of the automated control system for the box folding production line, depending on the technical parameters of the line and the parameters of the boxes to be bent. This will make it possible to choose optimal technological modes of the production process and obtain high quality parameters of cardboard packaging products. To verify the mathematical model of the production line, software has been developed in the Delphi development environment, which was applied with the developed automated production process control system based on a programmable logic controller (PLC) and an operator panel. This produced a number of results, in particular, controlling the speed of the hook bend in proportion to the speed of the line. And also provided an opportunity to increase line speed and, accordingly, production productivity. It has been possible to change the mutual location of system elements, which made it possible to reduce the distance between workpieces and increase the capacity of the line tape by 30 %.
The obtained research results were implemented at the production enterprise of typographic products «Dinas» (Zaporizhzhia, Ukraine), which contributed to the improvement and optimization of production processes. Conducting further research will provide an opportunity to expand the proposed methodology for use on all types of folding and gluing lines.
Three-dimensional simulation of spontaneous rupture: The effect of nonuniform prestress
Authors: Day Steven M. 
Published: March 2024

abstract
We use a finite difference method to study crack propagation in a three-dimensional continuum, for conditions of both uniform and nonuniform prestress. The rupture criterion employed satisfies two fundamental physical requirements: it ensures finite stresses in the continuum and finite energy dissipation in crack extension. The finite stress numerical simulations exhibit abrupt jumps in rupture velocity when sharp changes in prestress are encountered on the crack plane, behavior analogous to that predicted theoretically for two-dimensional, singular cracks. For uniform prestress conditions, the slip velocity function is approximately a low-pass filtered version of that of a singular, constant rupture velocity crack. For nonuniform prestress, spatial variations of peak slip velocity are strongly coupled to spatial variations of rupture velocity.
For uniform prestress and low cohesion, rupture velocity is predicted to exceed the S-wave velocity in directions for which mode II (inplane) crack motion dominates. A subshear rupture velocity is predicted for directions of predominantly mode III (antiplane) crack motion. Introduction of stress heterogeneities is sufficient, in each of the three cases studied, to reduce average rupture velocity to less than the S velocity, but local supershear rupture velocities can still occur in regions of high prestress. Rupture models with significant segments of supershear propagation velocities may be consistent with seismic data for some large earthquakes, even where average rupture velocity can be reliably determined to be subshear.
