Authors: Dijkman Bea , Oosterhoff Alberta , Akanov Amangali , Paans Wolter 
Published: October 2021

Background:To strengthen nursing in Kazakhstan, an e-platform has been developed to support knowledge sharing and collaboration in nursing education, nursing research, and clinical practice.Objective:This study aims to identify and prioritize requirements for an e-platform to strengthen nursing in the trinity of nursing education, nursing research, and clinical practice.Methods:The research was conducted using an exploratory sequential mixed-method design, including a systematic review and a Delphi study. The systematic review utilized search terms concerning nursing, e-platform, research, and education. The Delphi study included two rounds of questionnaires among a panel of Kazakh and European experts. Outcomes were analyzed using content validity ratios and level of consensus thresholds.Results:The systematic review generated eight studies and identified nine categories of requirements to be covered by four groups in the Delphi study. These four groups were content-related, functional, usability, and technical requirements. The study generated 52 essential and 15 useful requirements, which are common in the literature and in experts’ opinions.Conclusion:The list of requirements is well embedded in the literature as well as in the national context of nursing in Kazakhstan. Therefore, the e-platform developed according to these requirements will contribute to improving the trinity of nursing education, research, and practice. Although the list is context-specific, when validated by a panel of experts, it is universally applicable when developing e-platforms for nursing.

Published: October 2021

Background:The fear of childbirth can range from apprehension to intense fear (tokophobia), with serious consequences for maternal health. Therefore, a standardized scale is needed to measure the fear of childbirth before pregnancy.Objective:This study aimed to adapt the Childbirth Fear Prior to Pregnancy (CFPP) scale to the Brazilian context and analyse its validity and reliability.Methods:A cross-sectional survey was completed by 146 nursing students at two Brazilian universities. A committee of experts evaluated the cross-cultural adaptation of the CFPP scale. Construct validity was verified using item-total correlations and Exploratory Factor Analysis (EFA). The validity of divergent concurrent criteria was evaluated by associating the score obtained using the Brazilian CFPP with the Depression, Anxiety, and Stress Scale (DASS-21). Reliability was analysed using Cronbach’s alpha coefficient and test-retest.Results:Correlation analysis revealed a predominance of moderate inter-item correlation and strong item-total correlation (>0.62). The EFA indicated that all items related to a single factor, with factor loadings and communalities >0.5. These results reinforced the one-dimensionality of the Brazilian CFPP. The validity of divergent concurrent criteria was confirmedviaweak correlations with DASS-21 scores (r = 0.32, p < 0.001). The Cronbach’s alpha (0.86) and the intra-class correlation coefficient (0.99) indicated reliability and strong temporal stability, respectively.Conclusion:The Brazilian version of the CFPP provides evidence of validity and reliability to measure fear of childbirth before pregnancy in young adults in Brazil.

Background
There is limited evidence in Africa on the design and development of mobile health (mHealth) applications to guide best practices and ensure effectiveness. A pragmatic trial for HIV pre-exposure prophylaxis roll-out among key populations in Tanzania is needed.

Objective
We present the results of the development of a mobile app (Jichunge) intended to promote adherence to pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) and female sex workers (FSW) in Tanzania.

Methods
A participatory design approach was employed and guided by the information system research framework. MSM and FSW were the target populations. A total of 15 MSM and 15 FSW were engaged in the relevance and design cycles, while the piloting phase included 10 MSM and 20 FSW.

Results
The relevance cycle enabled the description of the existing problem, provided the compatible app features for the target population, and identified the need to develop an mHealth app that provides health services in a stigmatizing and discriminating environment. User involvement in the app’s design and evaluation provided an opportunity to incorporate social, cultural, and community-specific features that ensured usability. In addition, the participants suggested valuable information to inform the app, text message services, medication registration, and chat platform designs.

Conclusions
The participatory design approach in the development of mHealth apps is useful in identifying and validating population-specific functional features, improve usability, and ensuring future health impacts. Through this participatory process, the Jichunge app took end-user needs, perspectives, and experiences into account, eliciting enthusiasm regarding its potential role in supporting pre-exposure prophylaxis adherence for HIV and related behavioral change promotion.

Authors: Wood Sarah M , Pickel Julia , Phillips Alexis W , Baber Kari , Chuo John , Maleki Pegah , Faust Haley L , Petsis Danielle , Apple Danielle E , Dowshen Nadia , Schwartz Lisa A 
Published: October 2021

Background
Data regarding the acceptability, feasibility, and quality of telehealth among adolescents and young adults (AYA) and their parents and caregivers (caregivers) are lacking.

Objective
The aim of this study was to assess the noninferiority of telehealth versus in-person visits by comparing acceptability with respect to efficiency, effectiveness, equity, patient-centeredness, and confidentiality.

Methods
Cross-sectional web-based surveys were sent to caregivers and AYA following video visits within an Adolescent Medicine subspecialty clinic in May-July 2020. Proportions of AYA and caregivers who rated telehealth as noninferior were compared using chi-squared tests. Feasibility was assessed via items measuring technical difficulties. Deductive thematic analysis using the Institute of Medicine dimensions of health care quality was used to code open-ended question responses.

Results
Survey response rates were 20.5% (55/268) for AYA and 21.8% (123/563) for caregivers. The majority of the respondents were White cisgender females. Most AYA and caregivers rated telehealth as noninferior to in-person visits with respect to confidentiality, communication, medication management, and mental health care. A higher proportion of AYA compared to caregivers found telehealth inferior with respect to confidentiality (11/51, 22% vs 3/118, 2.5%, P<.001). One-quarter (14/55) of the AYA patients and 31.7% (39/123) of the caregivers reported technical difficulties. The dominant themes in the qualitative data included advantages of telehealth for efficiency and equity of health care delivery. However, respondents’ concerns included reduced safety and effectiveness of care, particularly for patients with eating disorders, owing to lack of hands-on examinations, collection of vital signs, and laboratory testing.

Conclusions
Telehealth was highly acceptable among AYA and caregivers. Future optimization should include improving privacy, ameliorating technical difficulties, and standardizing at-home methods of obtaining patient data to assure patient safety.

Published: October 2021

Background and objectives
Current race-based eGFR calculators assign a higher eGFR value to Black patients, which could affect the care of kidney transplant candidates and potential living donors.

Design, setting, participants, & measurements
We conducted a survey of staff at adult kidney transplant centers in the United States (December 17, 2020 to February 28, 2021) to assess opinions on use of race-based eGFR equations for waitlisting and living donor candidate evaluation, availability of serum cystatin C testing and measured GFR, and related practices.

Results
Respondents represented 57% (124 of 218) of adult kidney transplant programs, and the responding centers conducted 70% of recent kidney transplant volume. Most (93%) programs use serum creatinine–based eGFR for listing candidates. However, only 6% of respondents felt that current race-based eGFR calculators are appropriate, with desire for change grounded in concerns for promotion of health care disparities by current equations and inaccuracies in reporting of race. Most respondents (70%) believed that elimination of race would allow more preemptive waitlisting for Black patients, but a majority (79%) also raised concerns that such an approach could incur harms. More than one third of the responding programs lacked or were unsure of availability of testing for cystatin C or measured GFR. At this time, 40% of represented centers did not plan to remove race from eGFR calculators, 46% were planning to remove, and 15% had already done so. There was substantial variability in eGFR reporting and listing of multiracial patients with some Black ancestry. There was no difference in GFR acceptance thresholds for Black versus non-Black living donors.

Conclusions
This national survey highlights a broad consensus that extant approaches to GFR estimation are unsatisfactory, but it also identified a range of current opinions.

MOMENT LYAPUNOV EXPONENTS AND STOCHASTIC STABILITY OF A THIN-WALLED BEAM SUBJECTED TO AXIAL LOADS AND END MOMENTS
Authors: Janevski Goran , Kozić Predrag , Pavlović Ratko , Posavljak Strain 
Published: October 2021

In this paper, the Lyapunov exponent and moment Lyapunov exponents of two degrees-of-freedom linear systems subjected to white noise parametric excitation are investigated. The method of regular perturbation is used to determine the explicit asymptotic expressions for these exponents in the presence of small intensity noises. The Lyapunov exponent and moment Lyapunov exponents are important characteristics for determining both the almost-sure and the moment stability of a stochastic dynamic system. As an example, we study the almost-sure and moment stability of a thin-walled beam subjected to stochastic axial load and stochastically fluctuating end moments. The validity of the approximate results for moment Lyapunov exponents is checked by numerical Monte Carlo simulation method for this stochastic system.

Energy­Saving Lighting of Agricultural Premises and its Parameters Calculation
Authors: Yuferev L. Yu. 
Published: October 2021

he properly selected lighting for livestock farms is noted to ensure the optimal productivity of bred animals and poultry and to generate profit for the enterprise. (Research purpose) The research purpose is to substantiate the parameters of energy-saving lighting for agricultural premises and to develop methods for its calculation. (Materials and methods) It has been shown that greenhouse farms most often use high and low pressure sodium lamps for lighting, but their spectrum only partially substitutes the natural one. It has been assumed that expanding the spectrum and approximating it to the solar one could improve product quality and yield. It has been stated that incandescent and fluorescent lamps are traditionally used to illuminate livestock and poultry premises, but they cannot create a lighting system with a «dawn - sunset» function, and their spectrum does not correspond to the full range perceived by animals and birds. It has been noted that the LED light sources’ functioning has such features that make the application of standard calculation methods impossible. We obtained formulas for calculating the light level and flux of photons. (Results and discussion) We provided examples of applying the energy-saving lighting systems developed by us in poultry houses with floor housing system, in cowsheds with tethered housing system and in an experimental phyto-laboratory for growing seedlings. It has been found that after replacing the lighting system based on DRL-125 lamps with a new one, with 36 nine-watt LED lamps, the power consumption decreased from 2,250 to 336 watts, the average light level increased and amounted to 90 lux, while the illumination uniformity and color rendition improved. We have developed a resonant power supply system for LEDs to create lighting systems with a «sunrise - sunset» function. (Conclusions) We have shown the possibility and provided examples of using the developed by us energy-saving controlled lighting systems based on LED light sources.

Published: October 2021

Abstract. The authors showed the relevance of creating agricultural machines using an electric drive. (Research purpose) The research objective is to develop an experimental prototype vehicle using an electrical schematic diagram of charge and electric drive control. (Materials and methods) The VAZ 111 Oka car was chosen as an experimental vehicle model with an electric drive, since it has a light weight of 645 kilograms, a simple design and a low cost. Mechanical characteristics of the electric motor were calculated and a frequency converter was chosen to control the electric drive. Laboratory bench tests were conducted. (Results and discussion)The authors installed storage batteries to power the electric drive, developed an electrical circuit schematics getting charged from a 220 volt alternating voltage network, and received graphs for the discharge of a 40-storage-battery power supply. (Conclusions) An electrical schematic diagram of charge and electric drive control was developed and implemented on an experimental vehicle model. It was determined that at the electric motor continuous operation with the load current of 1 ampere, the batteries get discharged within 104 minutes; with the current load of 2 amperes, they get discharged within 83 minutes; with 3 amperes – within 65 minutes, and with 5 amperes – within 50 minutes, which is enough to drive around the farm. The authors graphically depicted the dependence of the available capacity level on the voltage, as well as the batteries’ discharge on the time at various load currents. The authors carried out two experimental studies on storage batteries’ charging from alternating voltage with the current of 2 and 3 amperes: in the first case, the charging time was 350 minutes, in the second – 310 minutes. It was found out that when using the developed scheme, the batteries are charged evenly.

Published: October 2021

The authors studied the scientific and technical literature regarding the microclimate influence on dairy cattle productivity. It was found out that the building microclimate parameter deviation from certain limit values reduces milk yield by 10-20 percent decrease the live weight gain by 20-30 percent increases the mortality of young animals by 5-40 percent and reduces the number of lactations by 15-20 percent for the herd. (Research purpose) To conduct a survey of modern microclimate systems and their technical implementation for livestock buildings, suggesting the best option while reducing energy costs. (Materials and methods) A classification scheme was provided for microclimate systems. The factors affecting the microclimate of livestock premises were presented in one figure. The main functions of ventilation systems in animal husbandry were identified. The conditions for the use of natural and forced (tunnel) ventilation systems were described. The devices for changing the microclimate on the premises were presented. The possibility of using an overlapped ridge in the area of the roof ridge was considered to catch the airflow and minimize moisture penetration. (Results and discussion) To decrease energy consumption, it was proposed to shift from a supply ventilation system to a natural and hybrid ventilation system, which contains an air removal system, lighting equipment, heating elements, sensors, fans with spray nozzles, sashes. (Conclusions) It was found out that in summer, natural ventilation is unable to prevent heat stress from cows. It was determined that in case of heat stress within 60 days, losses could amount to 4.2 million rubles. To ensure optimal microclimate conditions and reduce costs from heat stress, it was proposed to use an innovative natural and hybrid ventilation system. The calculations showed that a 60-day energy consumption of the proposed system equals 264 thousand rubles.

This goal of this study is to describe the types of directive illocutionary act and to find out the most dominant directives speech act performed by the characters in The Complex: Lockdown movie through the theory of Speech Act by Kreidler (1998) and supported by the theory from Searle (1979). In analyzing the data, descriptive qualitative method is used. This study found 73 data of directive illocutionary act performed by the characters in the movie. In addition, it was found the most dominant directives used is command with 27 (37%) occurences followed by question with 23 (32%) occurences. Both types of directive is the most commonly used because the characters are forced to do a certain task quickly with a limited time to think. That causes they gave command to other and asked question frequently during the emergency situation after several bio-weapon attacks. The least dominant types of directive speech act are found namely; request with 16 (22%) occurences and followed by suggestion with 7 (9%) occurences.

Published: October 2021

This study concerns with the code switching found in Cinta Laura's video on her Instagram TV. Descriptive qualitative method is used for analyzing the data from ten videos. This study used the theory proposed by Poplack (1980) about types of code switching and the theory from Hoffman (1991) about the reasons of code switching. This study shows that there are three types of code switching found and six reasons of code switching found. The result of this study shows that intra-sentential switching is the most frequently used in types of code switching and particular topic is the most frequently used in the reasons of code switching. The phenomenon of code switching occurs in many media such as social media. By doing code switching, it is easier to build a sense of solidarity rather than using only one language. Therefore, code switching is an interesting topic to discuss in sociolinguistics research.
