PurposeSites of highest dominant frequency (HDF) are implicated by many proposed mechanisms underlying persistent atrial fibrillation (persAF). We hypothesized that prospectively identifying and ablating dynamic left atrial HDF sites would favorably impact the electrophysiological substrate of persAF. We aim to assess the feasibility of prospectively identifying HDF sites by global simultaneous left atrial mapping.MethodsPersAF patients with no prior ablation history underwent global simultaneous left atrial non-contact mapping. 30 s of electrograms recorded during AF were exported into a bespoke MATLAB interface to identify HDF regions, which were then targeted for ablation, prior to pulmonary vein isolation. Following ablation of each region, change in AF cycle length (AFCL) was documented (≥ 10 ms considered significant). Baseline isopotential maps of ablated regions were retrospectively analyzed looking for rotors and focal activation or extinction events.ResultsA total of 51 HDF regions were identified and ablated in 10 patients (median DF 5.8Hz, range 4.4–7.1Hz). An increase in AFCL of was seen in 20 of the 51 regions (39%), including AF termination in 4 patients. 5 out of 10 patients (including the 4 patients where AF termination occurred with HDF-guided ablation) were free from AF recurrence at 1 year. The proportion of HDF occurrences in an ablated region was not associated with change in AFCL (τ = 0.11, p = 0.24). Regions where AFCL decreased by 10 ms or more (i.e., AF disorganization) after ablation also showed lowest baseline spectral organization (p &lt; 0.033 for any comparison). Considering all ablated regions, the average proportion of HDF events which were also HRI events was 8.0 ± 13%. Focal activations predominated (537/1253 events) in the ablated regions on isopotential maps, were modestly associated with the proportion of HDF occurrences represented by the ablated region (Kendall’s τ = 0.40, p &lt; 0.0001), and very strongly associated with focal extinction events (τ = 0.79, p &lt; 0.0001). Rotors were rare (4/1253 events).ConclusionTargeting dynamic HDF sites is feasible and can be efficacious, but lacks specificity in identifying relevant human persAF substrate. Spectral organization may have an adjunctive role in preventing unnecessary substrate ablation. Dynamic HDF sites are not associated with observable rotational activity on isopotential mapping, but epi-endocardial breakthroughs could be contributory.

BackgroundSome studies found that family doctor contract services (FDCSs) had positive impact on the self-measurement behaviors of hypertension patients. However, evidence concerning the association between FDCSs and blood pressure measurement awareness among hypertension patients is not clear.ObjectiveThis study aims to explore the relationship between FDCSs and blood pressure measurement awareness among the hypertension patients, and examine whether there is a difference in this relationship among middle-aged and aged adults in rural Shandong, China.MethodsA multi-stage stratified random sampling was adopted in 2018 in Shandong Province to conduct a questionnaire survey among the sample residents, in which 982 hypertension patients were included in the study. Pearson chi-square test and logistic regression model were employed using SPSS 24.0 to explore the association between FDCSs and blood pressure measurement awareness.Results76.8% of hypertension patients would measure blood pressure regularly. The blood pressure measurement awareness of the signing group was significantly higher than that of the non-signing group when controlling other variables (P &lt; 0.001, OR = 2.075, 95% CI 1.391–3.095). The interaction of age and contracting status were significantly correlated with blood pressure measurement awareness (P = 0.042, OR = 1.747, 95% CI 1.020–2.992; P = 0.019, OR = 2.060, 95% CI 1.129–3.759). Factors including gender (P = 0.011, OR = 0.499, 95% CI 0.291–0.855), household income (P = 0.031, OR = 1.764, 95% CI 1.052–2.956), smoking status (P = 0.002, OR = 0.439, 95% CI 0.260–0.739), sports habits (P &lt; 0.001, OR = 2.338, 95% CI 1.679–3.257), self-reported health (P = 0.031, OR = 1.608, 95% CI 1.043–2.477), distance to the village clinic (P = 0.006, OR = 1.952, 95% CI 1.208–3.153) and medications (P &lt; 0.001, OR = 3.345, 95% CI 2.282–4.904) were also found to be associated with the blood pressure measurement awareness of hypertension patients.ConclusionThe government should take efforts to strengthen publicity and education of family doctors and pay more attention to uncontracted, middle-aged, female patients and patients with unhealthy life behaviors to improve the blood pressure measurement awareness.

Published: March 2022

BackgroundAntimicrobial resistance is one of the many health challenges worldwide, particularly in resource-limited countries like Ethiopia. Increasing knowledge of health professionals can reduce the occurrence of antimicrobial resistance. In this study, we determined the antimicrobial resistance knowledge and examined the associated factors among the University of Gondar Hospital health professionals.MethodsAn institution-based cross-sectional survey was carried out. The samples were randomly recruited. Statistical analysis was performed by using the statistical package for social sciences (SPSS) version 20 after entering the data using Epidemiological information (Epi-Info). To identify associated factors, the authors executed binary logistic regression and multivariate analysis wherein the statistical significance was decided at p &lt; 0.05.ResultsFour hundred and twelve health professionals with ages ranging from 20-60 years and mean age of 29.9 years took part in the study. Fifty-three-point-four percent of participants were males. The majority of the total respondents (84.7%, 95% CI: 80.08–88.30) had good knowledge of antimicrobial resistance. It was found that being male (AOR = 1.94, 95% CI: 1.10, 3.52), a work experience of 6–10 years (AOR = 2.45, 95% CI: 1.28, 4.68), having 30–38working hours per week (AOR = 3.93, 95% CI: 1.38, 5.11), and antibiotic intake (AOR = 3.71, 95% CI: 1.75, 7.87) were significant factors of antimicrobial resistance knowledge.ConclusionIn the current study, about 84.5% of health professionals had good knowledge of antimicrobial resistance. Reducing working hours per week and increasing the experience of workers are recommended to increase the knowledge on AMR.

Taenia soliumcysticercosis is the most common cause of acquired epilepsy in pig-raising and pork-consuming parts of Africa, Latin America, and Asia. This review aimed to systematically compile and synthesize data on the epidemiology of porcine cysticercosis in the Eastern and Southern Africa (ESA) region. Comprehensive searching strategies were employed to retrieve the studies published or reported between January 1,1997 and March 1, 2021, from Pub Med, Hinari, and Google Scholar databases and search platforms. The identified studies that met the inclusion criteria were then appraised for methodological quality. Finally, 44 studies obtained from nine countries were selected and included in this review. Relevant data were extracted using standardized templates for qualitative synthesis and meta-analysis. The overall pooled prevalence estimate of porcine cysticercosis in the ESA region was 17% (95% CI: 14–20%). The prevalence level between and within countries showed high variability. The pooled estimate showed high heterogeneity among the reports (the inverse variance index value (I2) of 98.99%,p&lt; 0.05). The meta-analysis sub-grouped by the type of diagnostic test showed the pooled prevalence estimate of 27% (95% CI: 9–50) by carcass dissection; 23% (95% CI: 14–33) by Antibody-based immunodiagnostic techniques; 23% (95% CI: 18-29) by antigen detecting (Ag)-ELISA, 12% (95% CI: 7–18) by meat inspection, and 9% (95% CI: 7-11) by lingual examination. The meta-analysis sub-grouped by region showed a relatively higher pooled prevalence estimate for the Southern region 22% (95% CI: 15–30) compared to 13% (95% CI: 11–15) in the Eastern region. The highest country-based pooled prevalence was obtained from South Africa (33%, 95% CI: 20–48) and Zambia (22%, 95% CI: 16–29), whereas the lowest pooled prevalence was identified in Madagascar (5%, 95% CI: 4-5) and Rwanda (7%, 95% CI: 6–8). The lack of latrine, traditional pig husbandry practices, unprotected water sources, and increase in age were identified as significant risk factors for the occurrence of porcine cysticercosis in the pooled studies. The findings of this review will provide context-specific input to prioritize the possible intervention programs forT. soliumcontrol in the ESA region. More sensitive and specific test-based prevalence estimates, detailed risk factor investigations, and financial losses analysis are needed to establish feasible control strategies.Systematic Review Registrationhttp://www.crd.york.ac.uk/PROSPERO/, identifier: CRD42021238931.

Published: March 2022

BackgroundAlthough positive safety leadership has attracted increasingly academic and practical attention due to its critical effects on followers' safety compliance behavior, far fewer steps have been taken to study the safety impact of laissez-faire leadership.ObjectiveThis study examines the relationships between safety-specific leader reward and punishment omission (laissez-faire leadership) and followers' safety compliance, and the mediations of safety-specific distributive justice and role ambiguity.MethodsOn a two-wave online survey of 307 workers from high-risk enterprises in China, these relationships were tested by structural equations modeling and bootstrapping procedures.ResultsFindings show that safety-specific leader reward omission was negatively associated with followers' safety compliance through the mediating effects of safety-specific distributive justice and role ambiguity. Safety-specific leader punishment omission was also negatively associated with followers' safety compliance through the mediating effect of safety-specific role ambiguity, while safety-specific distributive justice was an insignificant mediator.OriginalityThe study addresses and closes more gaps by explaining how two contextualized laissez-faire leadership measures relate to followers' safety behaviors, following the contextualization and matching principles between predictors, mediators and criteria, and by revealing two mechanisms behind the detrimental effects of laissez-faire leadership on safety outcomes.

Published: March 2022

BackgroundAltogether, 17 Sustainable Development Goals (SDGs) are an urgent call for action to end poverty, protect the planet, and ensure prosperity for all. Goal 3 is crucial in terms of good health and wellbeing. The main aim of this study is to analyze and evaluate differences among indicators of SDG 3: Sustainable health and wellbeing in the EU countries.MethodsThe status and development of the EU Member States regarding their successes or failures in terms of Goal 3 were subjected to analysis. Altogether, 11 indicators were used to rank the EU countries using the TOPSIS and ranking methods. The ranks were assigned to the countries in two periods. The first period is related to the time from 2010 till 2014, and the second period from 2015 till 2019.ResultsThe EU countries achieved a positive development in 10 of 11 indicators that monitor the achievement of the EU in terms of Goal 3. The only variable that changed negatively was the obesity rate. Positivity was observed in the decline of the standardized preventable and treatable mortality, which declined from 317.3 in the first period to 295 in the second period; the drop of the population weighted annual mean concentration of fine particulate PM2.5, from 16.4 to 13.6 μg/m3, and also in the increase of the share of people with good or very good perceived health, which was combined with a decrease of the self-reported unmet need for medical examination and care. The best-rated country in terms of SDG 3 was, in both periods, Sweden, while the worst-rated was Latvia.ConclusionsGovernments and institutions in the EU can intervene to increase the accessibility and quality of the health care system, but every citizen should try to do their best to reduce some of the risk factors, such as smoking or obesity, to try living healthier and to help to achieve higher ambitions in terms of sustainable health and wellbeing.
Public Perception of COVID-19 Vaccination in Italy: The Role of Trust and Experts’ Communication
Authors: Bucchi Massimiano , Fattorini Eliana , Saracino Barbara 
Published: March 2022

Objectives: Vaccination campaigns against COVID-19 throughout the world are not only a major organisational challenge, but also a communication and social challenge. Recent data from several countries show that a relevant proportion of citizens either do not plan to be vaccinated against COVID-19 or would rather postpone their vaccination. We argue that such attitudes are not the result of generalised scepticism about vaccination, nor of generalised distrust in science.Methods: We analysed data from three survey waves on attitudes to vaccination against COVID-19 conducted in Italy in October 2020, January 2021, and May 2021 in the context of the Science in Society Monitor.Results: Positive evaluations of experts’ communication and trust in their contribution—as well as in that of health institutions, local authorities, and healthcare workers—play a key role in understanding the willingness to be vaccinated.Conclusion: Relevant implications can be drawn in terms of communication efforts and institutional strategies that are essential to build effective and inclusive vaccination campaigns.
THERMODYNAMIC ANALYSIS OF HYDRATION PROCESSES OF CALCIUM ALUMINOFERRITES
Authors: Rahimbaev Sh. , Onoprienko N. , Rahimbaev I. 
Published: March 2022

The processes of hydration and hydrate phase formation of calcium aluminoferrites are insufficiently covered in the technical literature. Thermodynamic analysis of the hydration processes of calcium aluminoferrite of 4CaO·Al2O3·Fe2O3 is difficult due to the unreliability of the initial data for hydration products. The question of the basicity of calcium hydroferrites requires clarification. There is insufficient data on the justification of the method of calculating the thermodynamic properties of hydroferrite -∆G0298, - ∆H0298 and c(T), verification of their results, the mechanism of formation of the complex anion Fe(OH)4- and its stability in the liquid phase of hydrating C4AF.
The hydration of 4CaO·Al2O3·Fe2O3 with the formation of 2CaO·Al2O3·8H2O as hydrate phases is considered. The energy of hydrogen bonds between the layers of Ca(OH)2, Al2(OH)3 and Fe(OH)3, from which the hexagonal layers of these complex calcium, aluminum and iron hydroxides are composed, is compared. It is shown that the values of ∆G0298 and ∆H0298 2CaO·Fe2O3·8H2O, which are equal to -937.2 and -1082.3 kcal/mol, respectively, are not consistent with experimental data on the solubility of C2FH8 and the specific heat release during C4AF hydration (100-115 kcal/g). Values for C2FH8, ∆G0298= -933, ∆H0298 = -1072 kcal/mol are recommended. It is shown that the formation of Fe(OH)3 hydroxide in the amorphous state, rather than the Fe(OH)4 ion, is preferable as an intermediate product of C4AF hydration.

Introduction. Corporate social responsibility in human resource management today remains a topic of discussion among domestic and foreign scientists. After all, there are still no generally accepted methods for assessing the level of corporate social responsibility, as well as a proven relationship between corporate social responsibility and effective management of human resources.The aim of the study is to determine the place of corporate social responsibility in human resource management as a business-oriented approach to achieve high results in achieving the Sustainable Development Goals.Research methods. Google Tools were used to analyze the publication activity on the research topic and the data sample was generated from the scientometric database Scopus. Statistics from the State Statistics Service of Ukraine and the UN Global Compact were used. Comparative analysis was used in the study of key indicators that affect the level of corporate social responsibility at the micro and maro levels.Results. The obtained data confirmed the hypothesis of a strong close relationship between the studied phenomena - corporate social responsibility and human resource management. This led to the conclusion that increasing the level of corporate social responsibility in human resource management will allow to more effectively implement the key Sustainable Development Goals and to form a new corporate culture in the country.Perspectives. Requires further research into the level of the relationship between corporate social responsibility and human resource management, as well as the formation and improvement of methods for assessing the level of effectiveness of corporate social responsibility in human resource management.
Corporate social responsibility: the contribution of Ukrainian mobile operators to overcoming the consequences of the spread of COVID-19
Authors: Zhmai Aleksandr 
Published: March 2022

Introduction. The business challenges posed by the COVID-19 coronavirus pandemic have prompted companies to respond immediately to the situation and implement new CSR projects to support the community. All companies act differently: they give preferences to doctors, allocate funds for the purchase of equipment, organize remote work et cetra. At the same time, the question of the peculiarities and differences between different industries and within one industry remains almost unsolved.The purpose of this study is to analyze the activities of mobile companies in Ukraine in the field of corporate social responsibility. The contribution of companies in overcoming the consequences of the pandemic, what actions were taken and in what directions is also studied.Methods. To achieve this goal, general and special methods were used, namely: theoretical generalization, systematization, analysis and synthesis, economic and statistical methods of collecting and processing information, as well as the method of logical generalization - to draw conclusions.Results. The current situation in the social and economic spheres of Ukraine is described. The analysis of the mobile communication industry in Ukraine as one of the key ones in remote work and self-isolation is carried out, the market capacity and consumer needs are studied. The practices and measures of corporate social responsibility, which were implemented by key companies in this industry both in the years before the coronary crisis and in 2020, were studied.Prospects. On the one hand, it is worth investigating how corporate social responsibility will develop in companies operating in the field of mobile communications. After all, their external environment is also changing, and the problems caused by the emergence of COVID-19 have not yet been overcome. On the other hand, a similar analysis of companies in other industries will reveal who is really ready to change and adapt to new circumstances, and who will gradually lose their market positions.
Quantification of wafer bond strength under controlled atmospheres
Authors: Takeuchi Kai , Suga Tadatomo 
Published: March 2022

Abstract
Bond strength is the most reliable criterion of the wafer bonding quality. Water stress corrosion affects the bond strength, corresponding to the measurement atmosphere and residual moisture at the bonding interface. In this study, we developed a new methodology to measure the wafer bond strength including the water stress corrosion effect under the controlled atmospheres, namely, dry atmosphere, wet atmosphere, and vacuum. The developed method experimentally demonstrates the evaluation of the water stress corrosion by the surrounding air and the interfacial water separately. Furthermore, it is also indicated that the water stress corrosion depends on the bonding methods, such that the surface activated bonding using Si intermediate layer has high durability for corrosion and the hydrophilic bonding has low durability. This study will provide a new understanding of the relation between the bonding process and the water stress corrosion effect, especially for the interfacial water.
Fabrication of vertical-taper structures for silicon photonic devices by using local-thickness-thinning process

Published: March 2022

Abstract
This paper describes a simple fabrication process of vertical-taper structures which can locally tune the thickness of silicon photonic devices. For low-loss spot-size conversion, taper angles less than 10° are required. To fabricate the gradual-slope shape of the vertical tapers, we have developed a step-and-exposure lithography process, which is realized by repeated light exposure to photoresist and movement of the wafer stage by using commercial steppers. The process is conducted at a lower temperature (∼120 °C) than the conventional process and is compatible with the complementary metal-oxide-semiconductor process. Also, we have made a model of the lithography to predict the angle of the taper. Theoretical angles are consistent with the experimental results. We demonstrate the conversion of a 400 nm thick silicon waveguide to 220 nm, whose length was 2.4 μm and insertion loss was measured to be less than 0.3 dB. The process enables us to choose the optimal thickness for each silicon-photonic device.
