Drying characteristics of sludge in a rotary drum for fast-drying application
Authors: Xiao Yongli , Wang Hualin , Deng Shengan , Su Fuyong , Wen Zhi
Published: October 2020

High temperature metallurgical slag (temperature, >1450?C) and high moisture sludge (moisture content, >80 wt.%) are common wastes with huge outputs. Many problems, such as high cost, low level of harmlessness, and low efficiency, are encountered in current treatment methods. If these wastes can be recycled, they can be valuable secondary resources. Therefore, using the drum apparatuses to treat these two kinds of wastes is proposed. The process uses waste heat of slag to dry sludge with high moisture content and is a kind of alternative circulation treatment technology in which steel balls are used as ball milling media and intermediate heat carriers. Besides, this technology can break up slag or sludge in real time, thereby ensuring high heat or mass transfer rate. This study presents an experimental investigation of the dynamic drying process of wet sludge mixed with hot steel balls in a rotary drum. The relationship of operation parameters (including sludge moisture content, sludge treatment mass, steel ball diameter, and rotary speed of drum) and drying effect is obtained. There are three kinds of final drying results: completely dried to powder, few sludge agglomerations, and sludge-to-wall adhesion. If the operating parameters are set well, the sludge could be efficiently and completely dried and eventually in powder form.

Authors: Leino Abbie D. , Dorsch Michael P. , Lester Corey A.
Published: October 2020

Objective: The
objective was to evaluate statin utilization in the United States before and
after the 2015 ADA position statement, which expanded statin therapy
recommendations to include all adults 40-75 years old with diabetes.

Research
Design and Methods: The National Health and Nutrition Examination
Survey was used to obtain a representative sample. The difference-in-differences
technique determined the impact of the recommendation on the proportion of
people with diabetes for whom statin therapy was newly recommended.

Results: Among
people with diabetes, the change in statin utilization in people without ASCVD
risk factors controlling for change among people with ASCVD/risk factors was
6.6% (p=0.388). In the adjusted analysis, overt ASCVD, age, Black race, health
insurance, a place for routine care, and total cholesterol were significantly
associated with statin utilization (p<0.05).

Conclusion: The
most recent change in statin recommendations had minimal impact on the
proportion of patients receiving a statin.

Fostering Transferable Creativity: A Core Role for Art Education in School Curriculum
Authors: Cropley Arthur
Published: October 2020

Arts education occupies a fringe position in school curricula because the arts are widely regarded as accessible to only a chosen few and of little practical use, or as purely recreational. What is needed is understanding of the potential contribution of arts education to other areas of curriculum, including those often seen as the real core of school learning (“the three Rs”). The psychological processes and personal properties inherent to arts education correspond closely to those now regarded as vital right across the curriculum. In contrast, they are often neglected in conventional academic disciplines. Arts education is capable of promoting these processes and personal properties to transfer to other elements of the curriculum in the form of transferable creativity, but this will not occur without changes in mainline pedagogy, for example, in the assessment.

La otredad en la extimidad
Authors: Odetti Verónica Beatriz
Published: October 2020

El presente artículo busca destejer las nuevas configuraciones de la subjetividad en el contexto de la extimidad (Sibilia, 2008), es decir, pensar reflexivamente estos nuevos modos de ser y estar en las redes, poniendo especial atención a la configuración de las subjetividades desde la alteridad. Para tal fin se tensionan las propuestas teóricas de Lévinas, Maturana y Sibilia. Emerge entonces una nueva gestión del yo en sus coordenadas espaciales y temporales signadas por la virtualidad y las redes sociales, donde el rostro (Lévinas, 1987) y la legitimidad del otro (Maturana, 1997) adquieren presencia en un like o emojis o stikers. No hay rostro ni emociones que permitan configurar la alteridad, aparecen caricaturas que remedan emociones y que buscan suplir ese lugar del otro en la configuración de las subjetividades instantáneas, instagrameables y fugaces que se nos presentan.

Authors: KOWALSKA GRAŻYNA , KOWALSKI RADOSŁAW
Published: October 2020

Wzrost świadomości społeczeństwa w zakresie jakości i bezpieczeństwa żywności wynika przede wszystkim z postępu naukowego. Bezpieczny produkt albo nie stwarza żadnego niebezpieczeństwa, albo stwarza mało zagrożeń, które są uważane za akceptowalne w ramach wysokiego poziomu ochrony zdrowia i bezpieczeństwa ludzi. Można wymienić wiele substancji, których obecność w żywności jest niepożądana. Szczególnie niebezpiecznymi dla zdrowia i życia człowieka są metabolity grzybów strzępkowych określane mianem mykotoksyn. Jest to grupa związków bardzo zróżnicowanych pod względem chemicznym, co utrudnia analizę obecności tych substancji w różnorodnych próbkach pochodzenia rolniczego, w tym w żywności i paszach. W pracy zawarto przegląd literatury na temat metod oznaczania mykotoksyn z zastosowaniem różnych technik analitycznych jak: chromatografia cienkowarstwowa (TLC), wysokosprawna chromatografia cieczowa (HPLC) i chromatografia gazowa (GC) z różnymi wariantami detekcji oraz spektroskopia w bliskiej podczerwieni (NIR). Ponadto przedstawiono zastosowanie testów immunoenzymatycznych i metod opartych na biologii molekularnej, które stanowią alternatywne rozwiązania w stosunku do metod chromatograficznych.
Evaluation of subcutaneous administration of alfaxalone-midazolam and ketamine-midazolam as sedation protocols in African pygmy hedgehogs (Atelerix albiventris)
Authors: Hawkins Shawna J. , Doss Grayson A. , Mans Christoph
Published: October 2020

OBJECTIVE

To evaluate SC administration of 2 sedation protocols, ketamine-midazolam (KM) and alfaxalone-midazolam (AM), in African pygmy hedgehogs (Atelerix albiventris).

ANIMALS

9 healthy adult hedgehogs (5 males, 4 females).

PROCEDURES

A randomized, blinded, complete crossover study was performed. Sedation was induced by SC administration of either ketamine (30 mg/kg [14 mg/lb]) with midazolam (1 mg/kg [0.45 mg/lb]) or alfaxalone (3 mg/kg [1.4 mg/lb]) with midazolam (1 mg/kg), including a 2-week washout period between treatments. Flumazenil (0.05 mg/kg [0.02 mg/lb], SC) was administered 45 minutes after administration of either protocol to reverse the effects of midazolam. Physiologic variables, reflexes, and behaviors were monitored. Food intake and body weight were measured before and after sedation.

RESULTS

Deep sedation characterized by complete loss of the righting reflex, decreased jaw tone, decreased pelvic limb withdrawal reflex, and preservation of the palpebral reflex was produced in 7 of 9 hedgehogs after KM administration and all 9 hedgehogs after AM administration. Mean ± SD time to loss of righting reflex was 6.4 ± 2.4 minutes after KM administration and 10 ± 4.0 minutes after AM administration. Following flumazenil administration, no significant difference was found in recovery time between sedation with KM (18.8 ± 12.7 minutes) and AM (14.4 ± 7.8 minutes). No significant differences were found in respiratory rate, oxygen saturation, or body temperature between protocols, whereas heart rate was higher for sedation with KM. Both sedation protocols resulted in a transient reduction in food intake.

CONCLUSIONS AND CLINICAL RELEVANCE

Subcutaneous administration of KM and AM provided deep sedation that might be useful to facilitate routine, noninvasive procedures in hedgehogs.

Published: October 2020

According to health studies, reinforcing gelatin is necessary in order to obtain the multifunctional material. In this study, nano zinc oxide (ZnO; at concentrations of 0.5%, 1% and 1.5%) was doped with gelatin and the solution was electrospun under specific conditions to obtain multifunctional gelatin/ZnO nanofibers. The morphology of the nanofibers was studied by field emission scanning electron microscope (FESEM), and energy-dispersive X-ray spectrometry (EDX) analysis indicated the presence of nano Zn on the surface of gelatin fibers. On the contrary, elemental mapping analysis proved the distribution of nano material along the nano gelatin fibers. The results show that the produced nano gelatin/ZnO composite increases the ultraviolet (UV) blocking of fabric significantly. It is also observed that electrospun gelatin/ZnO nanofibers have excellent bactericidal property against both Bacillus cereus (Gram-positive) and Escherichia coli (Gram-negative) bacteria.
Evaluate the effects of metabolic syndrome in adolescents and children
Authors: Jia Rui-Min , Yan Xiao-Ning , Sun Jing
Published: October 2020

The metabolic syndrome (MS) in adolescents and children can cause serious consequences that lead researchers to pay efforts to study in such area. Presently, MS definition is still not standardized. Different versions of MS definition have been used by numerous studies, which may be a problem to identify MS and then to predict and prevent clinical diseases. The pediatric literature shows that insulin resistance and obesity might be the key underlying pathophysiology of MS to cause many related diseases. High prevalence of MS is in overweight and obese children and adolescents. This article focuses on such above issues and also effects of MS on two main disease outcomes: cardiovascular disease and type 2 diabetes.
Identifying Syrian refugees in Turkish microdata
Authors: Pinedo-Caro Luis
Published: October 2020

This article proposes a strategy to identify Syrian refugees in Turkey’s Household Labour Force Survey (HLFS). Even though Turkey’s HLFS contains information on the migrants’ year of arrival to Turkey, it does not provide details on their nationalities. This unfortunate feature mixes Syrian refugees with the standard flow of migration who arrived to Turkey during the Syrian war. I propose to eliminate the standard flow of migrants arrived between 2011 and 2017 by matching them (based on their characteristics) with the migrants arrived in the 2004–2010 period. This method obtains, indirectly, nonstandard migration, i.e., Syrian refugees. The results show that the age distribution of the nonstandard migrants identified matches the age distribution of Syrian refugees as officially released by the Turkish government. At last, I propose a post-stratification adjustment of the survey weights to find the actual geographical distribution of Syrian refugees in Turkey.
Advances in the diagnosis of GERD

Published: October 2020

Gastroesophageal reflux disease (GERD) is considered one of the most frequent chronic gastrointestinal diseases globally with high costs due to treatment and investigations.

First line therapy is with proton pump inhibitors, those who do not respond to initial treatment usually require further investigations such as upper gastrointestinal endoscopy or ambulatory 24-hours esophageal pH monitoring. The total time of exposure to acid and the DeMeester score represent the most useful parameters associated with conventional pH-metry, because they can identify gastroesophageal reflux disease.

Although pH-metry is considered the gold standard for the evaluation of gastroesophageal reflux disease, new impedance-based parameters have been introduced in recent years with the role of increasing the accuracy of diagnosing gastroesophageal reflux disease and characterizing the type of reflux. The development of multichannel intraluminal pH-impedance has improved the ability to detect and quantify gastroesophageal reflux. New parameters such as post-reflux swallowing peristaltic wave (PSPW) index and the mean nocturnal basal impedance (MNBI) have recently been introduced to assess GERD phenotypes more accurately. This review evaluates current GERD diagnotic tools while also taking a brief look at newer diagnostic parameters like PSPW and MNBI.

Published: October 2020

Background. The objective of our present study is to assess the relation between persistent fatigue and rheumatoid arthritis (RA) disease activity and its functional impact and to determine if the positive effect of biologics on fatigue is due to good disease response or to a different pathway.

Methods. A study cohort of patients with established RA was conducted. We included patients who had been prescried a biologic after at least failure of one conventional synthetic Disease Modifying Anti-Rheumatic Drug synthetic (csDMARDs). At baseline, patients had a moderately to highly active disease. Demographic characteristics, disease activity and functional impact were assessed by disease activity score (DAS28CRP) and health assessment questionnaire (HAQ) scores. Fatigue was evaluated by the Functional Assessment of Chronic Illness Therapy–Fatigue scale questionnaire (FACIT-F). Patients were examined before initiating biotherapy, then after three months and six months.

Results. Thirty women with RA, with a mean age of 52.5 years, were included. At baseline, 57% received anti-TNFα: Etanercept (n = 9), Adalimumab (n = 6), Infliximab (n = 2) and 43% received Rituximab. Good Eular response was obtained in 80% of patients at the third month and 97% of patients at the sixth month. In the analytic study, a significant amelioration after 3 months of biotherapy was found in both disease response (DAS28CRP) and fatigue (FACIT-F), respectively (p = 0.01, p<0.001 and p<0.001). The disease activity decreased significantly also after sixth month (p = 0.01, p<0.001 and p = 0.012). In the linear multivariate analysis, the regression of visual analogic pain (VAS pain) was the only predictors of the improvement of fatigue.

Conclusion. Biologics contribute to improve fatigue in patients with established RA and this effect seems to be independent from the clinical efficacy of this treatment.

Published: October 2020

Rotavirus is the most common cause of acute infectious diarrhea in infants and young children up to the age of five. The disease is characterized by profuse watery diarrhea, vomiting and fever. The major complications of rotavirus gastroenteritis (RVGE) are dehydration, middle ear inflammation and upper respiratory tract infection. The basis of treatment is compensation for fluid loss and administration of probiotics. The aim of this study was to analyze the clinical characteristics of rotavirus gastroenteritis in infants. The study was conducted by the type of retrospective-prospective clinical study on infants with rotavirus gastroenteritis diagnosed on the basis of a positive Rotalex test (Orion Diagnostica Finland) and exclusion of other etiological factors at the University Children's Clinic in Belgrade, from April 2005 to December 2010. In addition to the detailed medical history and clinical examination, relevant laboratory analyzes were performed in all patients. Descriptive and analytical statistical methods were applied in the study. Among the descriptive methods, we used grouping, tabulation, graphing, calculating measures of central tendency, calculating measures of variability and calculating relative numbers. Of the analytical statistical methods, distribution normality testing, χ2 test, Mann-Whitney U test and T test were used. Statistical significance will be taken to mean p < 0.05. The average infant mortality was 6.7 ± 3.7 months. All respondents were divided into two groups according to the age. The first group consisted of infants aged 0 to 5 months (46%), the second group consisted of infants aged 6 to 12 months (54%). The incidence of aqueous diarrhea (100%), vomiting (84%) and fever (74%) in infants suffering from rotavirus gastroenteritis was analyzed. The significance of the age on the symptomatology of rotavirus gastroenteritis as well as on the importance of using probiotics has been demonstrated.
Manet, Manebit! O “Manet e a Antiguidade italiana” de Aby Warburg como autorretrato psico-intelectual
Authors: Fleckner Uwe
Published: October 2020

O artigo traça o percurso de pesquisas de Aby Warburg sobre a produção pictórica de Édouard Manet e imagens de épocas pregressas para apresentar evidências do impacto desse trabalho não apenas ao entendimento do teórico sobre questões metodológicas envolvendo o trânsito histórico de motivos, como também na forma de uma reflexão autobiográfica e psicointelectual. A demonstração de relações imagéticas entre a Antiguidade, Rafaello Sanzio e Manet ocupa lugar central para Warburg, no sentido de construir uma genealogia da pintura Le déjeuner sur l’herbe (1863), que além de explorar o problema do Nachleben der Antike [Pós-vida do antigo] para além do âmbito do Renascimento ou Barroco, descortina um caminho em direção à expressão da emancipação humana na arte ocidental. Esse processo culminou na série de imagens Manet und die italienische Antike [Manet e a Antiguidade Italiana], trabalho que, além de indicar a identificação de Warburg com o pintor francês, também revelou um autodiagnóstico de uma existência maníaco-depressiva.

DEVELOPING FEMALE SCHOOL LEADERSHIP IN DISADVANTAGED SCHOOLS
Authors: Smit Brigitte
Published: October 2020

What can we learn from female leadership scholars that can be appropriated in the South Africa educational context? Little research is conducted to trace the qualities that characterise a feminine approach to leadership in contrast to the characteristics of the traditional approach of control, hierarchy, authority and division of labour. This conceptual article draws theoretically on relational leadership as a feminine approach to educational leadership. I argue that educational leadership in disadvantaged settings in South African schools requires strengthened collaboration and development, particularly for female school leadership. Such collaboration and development is possible through relational leadership.
EDUCATIONAL LEADERSHIP: THE AUDIENCE CREATES THE TEXT
Authors: Samuel Michael
Published: October 2020

Alternative conceptions of educational leadership that challenge the performativity culture do notÂ appear substantively to alter the trajectory of practitionerâ€™s everyday choices. This article uses as dataÂ the responses from three different audiences to a presentation on such alternative conceptions. TheÂ three groups were academics attending an educational leadership conference, circuit managersÂ as part of a post-project workshop, and a group of aspirant school rectors in a training diplomaÂ programme. The first two groups were South African and the third a Mauritian audience. TheÂ audience responses show how they subverted, re-interpreted and jettisoned the message of theÂ presentation. Three vignettes constitute the analysis of the audiencesâ€™ foregrounding of the livedÂ complexities of making alternative leadership choices. The article suggests we need to be awareÂ of how and why practitioners will choose or not to become alternative proponents of the dominantÂ discourses around â€˜educational qualityâ€™.
TOWARDS CULTURALLY CONTEXTUALISED PEDAGOGIES IN AFRICAN SCHOOLS
Authors: Schweisfurth Michele
Published: October 2020

Pedagogy is a complex phenomenon and efforts to reform it in African schools have more often led to more continuities and unintended consequences than wholesale change. This article explores how global norms of good pedagogy have travelled and considers the tensions between these and local practice. It calls for contextualised pedagogies that are responsive to local cultures and resource realities, but within a shared framework of evidence-based practice and childrenâ€™s rights.
HUMAN CAPITAL THEORY AND EDUCATIONAL POLICY STRATEGIES IN SUB-SAHARAN AFRICA: A RETROSPECTIVE OVERVIEW
Authors: Oketch Moses
Published: October 2020

Human capital theory is a powerful, and yet also viewed as a narrowly conceived, understanding of the benefits of education to individuals and society. For many years since its proper formulation in the early part of 1960, during which time education has been modelled as investment leading to economic growth and development, the theory has informed government policies in education and attracted criticism and generated debate over the tension concerning who benefits from education and how education should be organised and funded. This article reviews the influence of the theory in the education policy strategies of sub-Saharan Africa from the â€˜manpower planningâ€™ era, through the â€˜rate of returnâ€™ era, the â€˜endogenous growth and endogenous developmentâ€™ tenets and the debates over â€˜quality versus attainmentâ€™. These are all discussed in relation to educational access, expansion, finance and curriculum relevance.
Organisational Effectiveness in a Metropolitan Municipality: Proposing and Validating a Model
Authors: Olivier Benny , Martins Nico
Published: October 2020

The aim of this study was to propose and validate a model of organisational effectiveness which could be utilised by a metropolitan municipality to address problems and weaknesses in order to maintain its credibility in the eyes of the public and fulfil its legislatively prescribed mandate. As a first step, this study designed a conceptual model of organisational effectiveness for a metropolitan municipality by including organisational and behavioural variables published in previous studies, as well as variables contained in existing models of effectiveness. In order to validate the model, the next step was to conduct a cross-sectional survey using the Effectiveness Survey (ES) in an existing metropolitan municipality in South Africa (n = 6 514) and expose the data gathered to structural equation modelling (SEM). The confirmatory factor analysis that was conducted subsequently confirmed the existence of the three main variables proposed in the conceptual model, namely Healthy Systems, Goal Achievement and Service Delivery, but did not support all the hypothesised relationships between these variables. The implications of the statistically significant and insignificant relationships obtained are discussed and the utility of SEM as a means of validating a conceptual model is confirmed
The analyses of non-standard employment and contemporary labour protest in South Africa
Authors: Mathekga Jerry Mmanoko
Published: October 2020

This paper analyses the contemporary non-standard employment and labour unrest in South Africa, with special emphasis on the South African Post Office (SAPO) and universities across South Africa. The paper argues that attempts by SAPO and the universities to cut labour costs and to be more flexible and competitive through the use of non-standard employment have not reduced exploitation. Marginalisation, inequality, poor working conditions, lower wages and lack of protection and representation still prevail in most workplaces across the country, with companies and institutions still benefiting extensively. The paper relies on both primary and secondary sources. No empirical research has been done. It aims to advance knowledge of non-standard employment through discussion of this practice and of the entities in which it takes place. The impact of non-standard employment on workers is discussed. The paper also provides a critical view on non-standard employment.
Decrypting the nexus between organisational culture, quality of work life, job satisfaction and employee productivity in the public sector
Authors: Mafini Chengedzai
Published: October 2020

The recent recognition of the importance of the public sector as a major driver of economic success in any given country underlines the need to focus on strategies for enhancing the productivity of public sector employees. The aim of this paper is to examine the influence of organisational culture and quality of work life on job satisfaction and employee productivity among employees in the South African public sector. Using the quantitative survey research design, a questionnaire was developed and administered to a convenience sample of 264 employees drawn from central government departments in Gauteng. A confirmatory factor analysis was conducted to test the psychometric properties of measurement scales and hypotheses were tested using structural equation modelling. Organisational culture and quality of work life positively and significantly influenced job satisfaction. In turn, job satisfaction positively and significantly influenced employee productivity. Organisational culture exerted greater influence on job satisfaction than quality of work life. By implication, the labour relations environment in the public sector may be improved by nurturing healthy cultures and enriching quality of work life, thereby improving both job satisfaction and employee productivity.

A simple and ubiquitous model that is capable of accurately predicting the solubility in supercritical carbon dioxide would be invaluable for industrial and research applications. In this study, we present such a model for predicting dye solubility in supercritical carbon dioxide with ethanol as the co-solvent for a qualitatively diverse sample of eight dyes. A feed forward back propagation - artificial neural network model based on Levenberg-Marquardt algorithm was constructed with seven input parameters for solubility prediction, the network architecture was optimized to be [7-7-1] with mean absolute error, mean square error, root mean square error and Nash-Sutcliffe coefficient to be 0.026, 0.0016, 0.04 and 0.9588 respectively. Further, Pearson-product moment correlation analysis was performed to assess the relative importance of the parameters considered in the ANN model. A total of twelve prevalent semiempirical equations were also studied to analyze their efficiency in correlating to the solubility of the prepared sample. Mendez-Teja model was found to be relatively efficient with root mean square error and mean absolute error to be 0.094 and 0.0088 respectively. Furthermore, Grey relational analysis was performed and the optimum regime of temperature and pressure were identified with dye solubility as the higher the better performance characteristic. Finally, the dye specific crossover ranges were identified by analysis of isotherms and a strategy for class specific selective dye extraction using supercritical CO2 extraction process is proposed.

Network data is composed of nodes and edges. Successful application of machine learning/deep learning algorithms on network data to make node classification and link prediction has been shown in the area of social networks through which highly customized suggestions are offered to social network users. Similarly one can attempt the use of machine learning/deep learning algorithms on biological network data to generate predictions of scientific usefulness. In the present work, compound-drug target interaction data set from bindingDB has been used to train machine learning/deep learning algorithms which are used to predict the drug targets for any PubChem compound queried by the user. The user is required to input the PubChem Compound ID (CID) of the compound the user wishes to gain information about its predicted biological activity and the tool outputs the RCSB PDB IDs of the predicted drug target. The tool also incorporates a feature to perform automated In Silico modelling for the compounds and the predicted drug targets to uncover their protein-ligand interaction profiles. The programs fetches the structures of the compound and the predicted drug targets, prepares them for molecular docking using standard AutoDock Scripts that are part of MGLtools and performs molecular docking, protein-ligand interaction profiling of the targets and the compound and stores the visualized results in the working folder of the user. The program is hosted, supported and maintained at the following GitHub repository https://github.com/bengeof/Compound2Drug
Photocatalyst-Independent Photoredox Ring-Opening Polymerization of O-Carboxyanhydrides: Stereocontrol and Mechanism

Photoredox ring-opening polymerization of O-carboxyanhydrides allows for the synthesis of polyesters with precisely controlled molecular weights, molecular weight distributions, and tacticities. While powerful, obviating the use of precious metal-based photocatalysts would be attractive from the perspective of simplifying the protocol and enabling unexpected reactivity. Herein, we report the Co and Zn catalysts that are activated by external light to mediate efficient ring-opening polymerization of O-carboxyanhydrides, without the use of exogenous precious metal-based photocatalysts. Our methods allow for the synthesis of isotactic polyesters with high molecular weights (>200 kDa) and narrow molecular weight distributions (Mw/Mn < 1.1). Mechanistic studies indicate that light activates the oxidative status of CoIII intermediate that is generated from the regioselective ring-opening of the O-carboxyanhydride. We also demonstrate that the use of Zn or Hf complexes together with Co can allow for stereoselective photoredox ring-opening polymerizations of multiple racemic O-carboxyanhydrides to synthesize syndiotactic and stereoblock copolymers, which vary widely in their glass transition temperatures.

This study aimed to analyze the impact of interests, security risks, and financial behavior on new tools in transactions (e-money). Five direct relationships have been built resulting in two equations. To evaluate the model, the study distributed questionnaires to 110 respondents from seven different companies. With the use of path analysis, the model is then tested. On the basis of the statistical results, the findings show that consumer interest and safety risk have a positive and significant impact on financial behavior. To the relationship to electronic money, customer interest and financial behavior indicate a positive and significant relationship. Interestingly, customer safety risk did not show an insignificant result.
