Parameter identification of photovoltaic converter models
Authors: Obukhov S. G. , Plotnikov I. A. , Klimova G. N.
Published: October 2023

The work aims to develop a simple and effective method for identifying the parameters of photovoltaic converter (PV-cell) models for their wide practical application. An exponential model having one diode and ﬁve parameters is adopted as the basic model of the photovoltaic converter to facilitate its easy integration into MatLab/Simulink simulation software. To identify the parameters of models of photovoltaic converters, an original method based on ﬁnding the minimum of the root-mean-square error between model and experimental volt-ampere characteristics was used. The effectiveness of the method was conﬁrmed by determining the parameters of different models of photovoltaic modules based on various technologies: thin-ﬁlm Shell ST40, monocrystalline Shell SP70, and polycrystalline Kyocera KC200GT. A developed technique for constructing mathematical models of photovoltaic converters in order to reproduce their electrical characteristics is presented. The solution is easily implemented in Excel spreadsheet software with the “Search for Solution” add-on installed. The proposed universal method for identifying the parameters of photoconverter models can be used to build models of a wide range of photovoltaic modules and solar cells. The model current-voltage characteristics of the considered photovoltaic modules are shown to be in good agreement with experimental characteristics across a wide range of temperature and insolation conditions corresponding to their actual operation. Higher accuracy is achieved when using the proposed identiﬁcation method to determine the electrical parameters of mathematical models of photovoltaic converters than when using other well-known analytical and numerical methods. The result is a simple and effective method for constructing mathematical models of photovoltaic converters, which does not require the use of programming or the development of specialized numerical algorithms, allowing it to be used to solve many technical problems related to the design and operation of photovoltaic systems.

Published: October 2023

In this work, digital models for determining the electromagnetic inﬂuences of multi-wire traction networks on pipelines are developed. When developing models, an approach based on multiphase behaviour simulation of electric power systems was used. This approach adequately addresses all the inﬂuencing factors, which include modules and phases  of  currents  ﬂowing  through  the  overhead  contact  wire  suspension,  6–10–25  kV  power  transmission  lines  laid on the supports of the overhead line, and lines of rails. In addition, it is possible to take into account similar parameters for stresses at the nodal points of a multi-wire system. Among the key factors are the railway clearance when laying pipes parallel to the railway track, railway clearance trajectory in the presence of non-parallel sections, and the electrical characteristics of the soil along the clearance route. The research results demonstrated that a 25 kV electromagnetically unbalanced traction network exerts signiﬁcant inﬂuence on a pipeline running in parallel. It was shown that the maximum induced voltages at speciﬁc points along the pipe fall within the range of 300–700 V, which signiﬁcantly exceeds the permissible level of 60 V. It was revealed that currents exceeding 20 A ﬂowing through the pipe can have an adverse effect on anticorrosive protection devices. To mitigate electromagnetic impacts on the pipeline, the following measures are recommended: reducing the length of pipeline and railway clearance sections, increasing the gap between the traction network and the pipe, and installing an additional grounding source. The pipe can be connected to the supplementary grounding source through ﬁlters tuned to a frequency of 50 Hz, which involve capacitor units to prevent malfunctions during the operation of pipeline protection devices. Thus, the developed digital models allow the induced voltages generated by multi-wire traction networks and the currents ﬂowing through the pipes to be adequately determined. These models offer an informed choice of measures that ensure the safety of pipeline maintenance.

Published: October 2023

The study addresses the conformity of actual electricity consumption to the calculated value in electric distribution networks in which municipal consumers predominate in several cities of the Chelyabinsk region. To study the conformity between the speciﬁc electrical load established by regulatory documents and the actual value per apartment according to power consumption data in several cities of the Chelyabinsk region, the average annual power consumption by municipal consumers with a speciﬁc number of apartments was analyzed over a period of 2021–2022. The correspondence analysis of the average annual electricity consumption by municipal consumers in the studied facilities was carried out using the conventional method for calculating the electrical load over the given period following the guidelines outlined in SP 256.1325800.2016. The discrepancy between the actual electrical load on the apartment and its normative value established by the acting normative documents ranged from minus 48 to 300% with respect to electricity consumption. For the considered 16 objects located in the cities of the Chelyabinsk region, the discrepancy between the actual electrical load and the established normative values was compared. For 6 apartments, this discrepancy ranged from minus 58 to 155%. To improve the accuracy of forecasting electricity consumption and calculating electrical loads in electric distribution networks with a predominance of municipal consumers, methods using a new factor were recommended. This factor involves a generalized uncertainty coefﬁcient Ai, whose values are determined for the considered period. When using the developed methods, relative deviations in the forecast calculations are less than or equal to 10%.
Alumina production: Historical development, issues, and solutions. Part 1
Authors: Brichkin V. N. , Vasiliev V. V. , Maksimova R. I.
Published: October 2023

This study focuses on documenting the historical stages of aluminium and alumina production prior to the transition to a modern industry structure, involving the Hall-Héroult electrometallurgical process, and their technical signiﬁcance for the contemporary metallurgical complex. It highlights the signiﬁcance of these stages in the development of scientiﬁc knowledge related to alumina, aluminium, and their production technology when using chemical methods for obtaining metallic aluminium. The analysis includes aspects, such as classiﬁcation, technical evaluation of the processes, and the raw material base. It is shown that the formation of scientiﬁc knowledge regarding alumina and aluminium is mainly associated with the practical need for using alum and, to some extent, clay minerals. Since the commencement of deliberate research into methods for aluminium production in its elemental state and virtually until the 1890s, aluminium was primarily produced using the metallothermal methods pioneered by Henri St. Clair Deville and his colleagues due to the high thermodynamic stability of aluminium compounds and the absence of affordable energy sources. It was found that from 1854 to 1890, the production of aluminium by chemical method was associated with the use of sodium aluminium chloride (NaCl·AlCl3), natural cryolite, or synthesised ﬂuoride salts. Available technical reagents (aluminium sulphate, ammonia alum, and aluminium hydroxide), along with natural raw materials (cryolite, bauxite, and clay), were used as source materials in this period. The extraction and processing of bauxite were primarily associated with the production of alum and aluminium sulphate consumed by light industry. Although the demand for pure aluminium oxide was limited during the metallothermic production of aluminium, the driving force behind the advancement of modern technologies for alumina production was the demand for chemical products. This demand led to the development of technology for processing bauxite, which forms the foundation of the metallurgical complex in aluminium production using the Hall-Héroult electrometallurgical method.

The hormone luteinizing hormone (LH) is an important glycoprotein hormone that controls the activity of the gonadal organs, which in turn affects the physiology of the menstrual cycle. For LH to exert its effects, its specific receptor (LHR) must be expressed by cumulus cells. Objective: To determine the role of LH receptors (Luteinizing Hormone) in the regulation of human oocyte maturation processes Method:Systematic Literature Review (SLR). Data collection was conducted by documenting all articles based on predefined inclusion and exclusion criteria. A total of 10 national and international journal articles were retrieved from databases such as Google Scholar, PubMed, and Science Direct, using specific keywords related to the role of LH receptors and oocyte maturation. The literature search and study selection process followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Results:The highest expression of Luteinizing Hormone Receptor (LHR) observed in preovulatory follicles. Cumulus cell maturation, covering 100% of the oocytes, was 74%. FSHR and LHR mRNA expression levels increased with an increase in LH concentration in the in vitro maturation (IVM) medium. After 24 hours of IVM, there was a significant downregulation in the expression of LHR and FSHR.The mRNA and protein levels of FSHR and LHR in the cumulus-oocyte complex gradually decreased with increasing doses of FRBI in the IVM media compared to the control group. Majority of the cumulus cells from MII oocytes had RGS2/B2M gene expression of more than 50%. LH receptor expression in granulosa cells positively correlated with morphology, oocyte maturity, and fertility rate in the poor responder group. Granulosa cells from an agonist-triggered cycle with recombinant human chorionic gonadotropin (rhCG) for 24 hours were observed to increase viability, regulate mRNA expression of 3Î²-HSD, LH receptor, VEGF, and BCL-L2. More than 50% of the oocytes are matured after hCG injectionat an hCG concentration of 119.8 mIU/mL. Conclusion:LH needs receptor binding and expression for proper function, resulting in improved oocyte maturation with optimal LHR concentration which is 10 Âµg/mL LH. LHR expression is highest in preovulatory follicles. LHR expression increases during antral follicle growth. Supplementing media with hCG improves oocyte maturity with a 77 mIU/mL cutoff value. Supplementation with FRBI reduce LHR expression in COCs. The number of cumulus cells can also indicate the level of oocyte maturity, where cumulus cells covering 100% of the oocytes show the highest oocyte maturation.

Authors:   Endodontics Consultant, Hail Dental Center, Ministry Of Health, Hail, Kingdom Of Saudi Arabia., Ali Ahmed Aldawood Omran
Published: October 2023

The relationship between periodontal and endodontic disease has been controversial aspect for more than a century. Differentiating between these periodontal and endodontic disease is very difficult due their developmental, embryonic, anatomic and functional similarities. Nature pain is often considered as the first clue which should be supported by the radiographic and clinical evaluation for the correct diagnosis of the condition. Aim: The aim of this review was to develop a decision tree for easier and accurate diagnosis of periodontal and endodontic disease. A brief PubMed search was performed on endodontic and periodontal lesion using MESH terms endo-perio lesion, diagnosis of endoperio lesion, decision making of endo-perio lesion. In addition some websites and local guidelines were screened. By following the correct and appropriate diagnostics methods, accurate diagnosis of Endodontic -Periodontal disease can be done and the treatment for the particular condition could be achieved. Conclusion: With a decision tree, the diagnosis and pharmacological management of the pulpal and periapical diseases becomes easier for the dentist in regular clinical practice. A decision tree and a flow chart for daily practice which should be started up as soon as the patient presents with pain or swelling due to pulpal or periodontal periapical pathology. In this aspect active management of the infection can be done with sound knowledge on the endodontic periodontal lesions. Dentists are likely to encounter lesions that have both periodontal and endodontic aetiological components the so called perio-endo lesions. A thorough examination with appropriate investigations remains pivotal to diagnosing a perio-endo lesion. Correct diagnosis of such lesions is therefore important as it enables the most suitable clinical management to be treatment planned. It is still recommended, that for the treatment of perio-endo lesions, initial endodontic therapy is completed.

Onion production in Burkina Faso remains limited due to certain devastating diseases such as purple blotch caused by Alternaria porri.This disease causes significant yield losses and is difficult to control with chemicals.This difficulty could be linked to genetic, pathogenic and/or pathogenicvariability within populations of A. porri.The objective of the present study was to evaluate the morphological variability of Alternaria porri populations occuring in Burkina Faso with a view to better define appropriate methods in controlling the disease. Thus, fiftyisolates of A. porri, obtained from diseased onion leaves collected in the different agroclimatic zones, were morphologically characterized.Multivariate analyses were carried out on the data collected using XLSTAT 2016.7.02 software. These analyses revealed variability of A. porri in its morphological aspects such as colony color, radial growth and micropropagules production.All of the characterized isolates were grouped into three classes. Class 1 with 34 individuals, characterized by weak radial growth but high production of micro propagules. The second class composed of four isolates, is characterized by individuals with strong mycelial growth and a low capacity for the production of micro propagules.A third class, composed of twelve isolates, is characterized by intermediate individuals in terms of growth and production of micro propagules.However, this clustering into classes did not align with the geographic origin of the isolates. A pathogenicity study should be carried out with representatives of the three classes in order to understand whether this observed morphological variability is linked to the virulence of the fungus.

Palliative care aims to improve the quality of life for individuals facing life-threatening illnesses by addressing physical, psychological, social, and spiritual needs. While palliative care traditionally emphasizes symptom management and pain relief, the role of psychiatry in this field has gained recognition as an essential component of comprehensive patient-centred care. This case report provides an overview of the evolving role of psychiatry in palliative care, highlighting its significance in addressing the complex emotional and psychological aspects of end-of-life care.Psychiatrists play a crucial role in assessing and diagnosing mental health conditions that often co-occur with serious illnesses, such as depression, anxiety, and adjustment disorders. Identifying and addressing these conditions is vital to improving patients overall well-being. Psychiatric interventions are valuable in managing distressing psychological symptoms, including anxiety, depression, delirium, and existential distress. Appropriate pharmacological and psychotherapeutic interventions can alleviate suffering and enhance the patients overall comfort. Collaborating with Palliative care specialists, psychiatrists provide psychosocial support to patients and their families, helping them cope with the emotional challenges that arise during the end-of-life journey. This includes facilitating open and honest communication, addressing complex family dynamics, and assisting in advanced care planning.In conclusion, the role of psychiatry in palliative care is expanding to meet the complex needs of individuals facing life-limiting illnesses. Recognizing and addressing the emotional and psychological aspects of end-of-life care not only improves the patients quality of life but also contributes to a more compassionate and comprehensive approach to palliative care. Integrating psychiatry into palliative care services ensures that individuals receive the support they need to navigate the challenging journey of serious illness with dignity and comfort.

In Sinematiali, we observe the growth of fruit growing in this area which is traditionally marked by the production of cotton and cereals. This expansion induces a progressive transformation of land use patterns in the agrarian landscape and impacts agricultural practices. The present study is carried out to analyze agrarian changes in the sub-prefecture of Sinematiali between 1988, 1998 and 2021 using remote sensing techniques. From the processing of Landsat 5 TM (1988, 1998) and Landsat 8 OLI-TIRS (2021) satellite images, six (06) land use modes in the agrarian landscape were identified: dense dry forest, Savanna, Culture Ã¢Â€Â“ Perennial, Bare soil Ã¢Â€Â“ Place of habitation and Water. Survey data carried out with operators made it possible to analyze the determinants of the evolution of land use patterns in the eponymous sub-prefecture. Thus, from 1988 to 2021, we observe a reduction in the areas of annual cultivation Ã¢Â€Â“ fallow zones (-43%), dense dry forest (-58.6%) and savannah (-12.6%). On the other hand, the areas occupied by mango and cashew orchards increase from 478.85 ha in 1988 to 5,867.23 ha in 2021, i.e. an annual rate of change of 7.6% and an overall growth rate of 1,125.3%. This dynamic in fruit growing is partly due to the depreciation of profits from the marketing of seed cotton, the improvement in profit margins from the sale of mangoes, cashew nuts and the flexibility of maintenance orchards.

Internet addiction has become a potential issue in young people due to the accessibility and portability of digital media. The American Psychiatric Association has the vision to include Internet Use Disorder in the fifth edition of the Diagnostic and Statistical Manual for Mental Disorders (2012) for the first time, acknowledging the issues arising from this type of addictive disorder. This vision is based on a growing body of research. Due to the uneven development of their ability to set boundaries and exercise cognitive restraint, adolescents appear to be a demographic at risk for acquiring Internet addiction. The internet has become a powerful tool for removing physical barriers between people due to advancements in media and technology.However, excessive use of the Internet has resulted in negative consequences especially among the regular users labelling it as an addiction.

Published: October 2023

This paper delves into the intrinsic boundaries and limitations of the scientific method and its applications from an ontological, epistemic and moral perspective. It poses essential questions surrounding underlying presuppositions, basal unobservability and impracticality in science while aiming to be cognizant of the intricacies and subtleties that one encounters while asking questions that are elementary in nature. It seeks to give insight about the use of epistemic tools in science following which the applications of the scientific method are examined in purely human and moral domains. The latter part of the paper examines systemic issues that may inhibit the preservation of the Mertonian norms, intellectual honesty andhumility and scientific progress. The goal of the paper is to marry both philosophical and technical concerns surrounding the scientific method and to promote a newly emancipated science that is free from all intellectual dishonesty and needless conviction while maintaining a keen awareness of its own intrinsic limitations and presuppositions.

A research study conducted in Thailand aimed at developing and adding value to agricultural products, specifically focusing on bamboo. The agricultural sector in Thailand plays a significant role in the economy and society, employing a large portion of the population and generating income equal to approximately 9% of the countrys GDP. The government aims to enhance the competitiveness of Thai agricultural products and increase their value for the benefit of local communities.The research focuses on utilizing bamboo for construction projects, particularly in the form of Thai Dendrocalamus Giganteus bamboo (TDG) laminated columns (TDGLC). The study involves a production process to create man-made TDGLC and investigates the mechanical properties of these columns. The research examines the performance of parallel bamboo laminated columns under axial compression tests.Specimens of TDG bamboo, aged between 3 and 4 years, were cut into strips and clamped together to form columns of various lengths and cross-sections. The cross-section sizes ranged from 100 mm to 203 mm, with lengths of 1 meter, 2 meters, and 3 meters. The compression load and classification of long and short columns were analyzed based on the proportioning of length and cross-section.The research identified specific column types that exhibited either strength failure (short columns) or buckling failure (long columns). However, two column types, C603 and C402, showed mixed results, with both strength and buckling failures. Although their slenderness ratios exceeded 60, the primary mode of failure indicated that these specimens should be classified as short columns.It was observed that defects in the specimens influenced their load capacity, with higher slenderness ratios resulting in greater lateral deflection corresponding to the peak load. The equation used to calculate the load capacities aligned well with the test results. Overall, the study contributes to the understanding of TDGLC performance in construction applications and provides insights into the mechanical behavior of bamboo columns under axial compression.

Published: October 2023

The sudden note-ban (demonetization of Rs. 500 and Rs. 1000 notes) on 8th November 2016 in India left the country in a state of shock and uncertainty. This paper highlights the impact this demonetization had on Indias real estate sector, in the short run as well as the long run, and whether it was of overall benefit to the sector in the long run. It is a descriptive study which uses data collected from secondary sources and websites to analyze the main reasons the real estate sector was so largely impacted in the short run, key government policies and acts imposed during that time which impacted the real estate industry, the condition of the real estate sector pre and post demonetisation, the benefits and challenges to economic agents (buyers and sellers, primarily), and the long run consequence of this sudden move. The state of the real estate sector 5 years into demonetisation has also been considered, which has helped reach a conclusion as to whether or not this demonetisation was of an overall benefit to the real estate sector.

Radial artery cannulation is a common procedure for measuring invasive blood pressure, blood sampling and frequent blood gas analysis. Though considered safe, this procedure can lead to many complications which can be minor or of a serious nature. Minor complications include bleeding from the entry site and temporary occlusion of the artery. Serious complications may include permanent occlusion of the blood flow and resultant gangrene of the digits of the hand. It is very important to recognize the ischemic changes in the initial stage and manage them accordingly so as to minimize the tissue damage. Here we present a case where a patient developed sign symptoms of gangrene in the hand after the arterial cannula was removed. Apart from the medical management, surgical intervention was required to remove the thrombus.

The fall armyworm (FAW),Spodoptera frugiperda (Lepidoptera: Noctuidae) is a recent invasive pest species that has successfully established across sub-Saharan Africa. Management of FAW in its native range in the Americas has led to the development of resistance to many commercial pesticides before its arrival in Africa. Synthetic pesticides are often associated with issues such as pest resistance, persistent residue, non-target toxicity, and environmental issues. Therefore, the research and development of novel, safe, and effective pesticides has become a focus in pesticide discovery. Pesticide use may therefore be ineffective for FAW control in Africa, so new and more sustainable approaches to pest management are required that can help reduce the impact of FAW pest. Pesticidal plants provide an effective and established approach to pest management in African smallholder farming and recent research has shown that their use can be cost-beneficial and sustainable. In this study, crude leave extracts of three plants aloe secundiflora, nicotiana tabacum and teprosia vogelii were evaluated against fall armyworm (spodoptera frugiperda). Two different concentrations, 30mg/L and 15mg/L were evaluated in this study against second instar FAW larvae and eggs. The results indicated that these leave extracts caused a larval and egg mortalities of different levels. On average leave extracts of aloe secundiflora, teprosia vogelii and nicotiana tabacum caused larval mortalities of 80%, 63.33% and 93.33% respectively for 30mg/L concentrations while the average larval mortalities for aloe secundiflora, teprosia vogelii and nicotiana tabacum were 26.67%, 33.33% and 80.0% respectively for the 15mg/L concentrations. The egg mortalities were relatively low compared to larval mortalities for the two concentrations used in this study. On average the leave extracts of aloe secundiflora, teprosia vogelii and nicotiana tabacum caused the egg mortalities of 16.67%, 13.33% and 43.33% respectively when 30mg/L were used while the average egg mortalities for aloe secundiflora, teprosia vogelii and nicotiana tabacum were 3.33%, 0.0% and 26.67% respectively for the 15mg/L concentrations. It follows that nicotiana tabacum showed high larval and egg mortalities for both concentrations compared to the other two leave extracts and therefore good pesticide for the control FAW larvae and eggs.

Introduction: Neonatal sepsis is a clinical syndrome resulting from pathophysiologic effects of local and systemic infection in the 1st month of life. Septicemia usually consists of bacteremia with a constellation of signs and symptoms caused by microorganisms or their toxic products in the circulation. Neonatal sepsis was one of the common causes of neonatal mortality, contributing to 16% of all intramural deaths. Early diagnosis of neonatal septicemia is a vexing problem because of its nonspecific clinical picture. Method: This study was prospective observational study of 210 Cases received from August 2020 to August 2022 for Neonatal Sepsis. This prospective study was carried out in Department of Pathology of a tertiary care teaching hospital. The ethical permission has been obtained from Institutional Ethics Committee for conducting the study. Hemogram was obtained for each case using five part automated hematology analyser. Result: Hematological scoring system was useful test in the early diagnosis of neonatal sepsis. Diagnostic accuracy was 92.39% in this study,>=3 score was sensitive and >=4 score was specific for early diagnosis of neonatal sepsis Conclusion: The HSS increases the diagnostic accuracy of the complete blood cell count as a screening test for sepsis and simplifies and standardizes its interpretation.

Las aulas multigrado ofrecen numerosos beneficios y posibilidades educativas, y no sólo en los entornos rurales. Sin embargo, son muchas las dificultades con las que se encuentra el profesorado de este tipo de aulas; entre otras, la falta de formación especializada o el insuficiente apoyo de la administración. El propósito de esta investigación es conocer la percepción del profesorado de las aulas multigrado de Galicia (España) respecto a las posibilidades de la multigraduación, las limitaciones y las propuestas de mejora necesarias para la optimización de este modelo educativo. Los resultados evidencian que la realidad educativa donde un porcentaje importante de la población escolar está atendida en aulas multigrado requiere medidas específicas que ayuden a los desafíos de esta tipología de aulas. Consecuentemente, es necesario el apoyo de la administración educativa y la consideración de la multigraduación no sólo como una estrategia que evita el cierre de las escuelas rurales, sino como modelo de innovación.  Urge hacer una apuesta que provoque una revalorización de este tipo de aulas.

Background

Repetitive negative thinking (RNT) is a key transdiagnostic mechanism underpinning depression and anxiety. Using “just-in-time adaptive interventions” via smartphones may disrupt RNT in real time, providing targeted and personalized intervention.

Objective

This pilot randomized controlled trial evaluates the feasibility, acceptability, and preliminary clinical outcomes and mechanisms of Mello—a fully automated, personalized, transdiagnostic, and mechanistic smartphone intervention targeting RNT in young people with depression and anxiety.

Methods

Participants with heightened depression, anxiety, and RNT were recruited via social media and randomized to receive Mello or a nonactive control over a 6-week intervention period. Assessments were completed via Zoom sessions at baseline and at 3 and 6 weeks after baseline.

Results

The findings supported feasibility and acceptability, with high rates of recruitment (N=55), uptake (55/64, 86% of eligible participants), and retention (52/55, 95% at 6 weeks). Engagement was high, with 90% (26/29) and 59% (17/29) of the participants in the Mello condition still using the app during the third and sixth weeks, respectively. Greater reductions in depression (Cohen d=0.50), anxiety (Cohen d=0.61), and RNT (Cohen d=0.87) were observed for Mello users versus controls. Mediation analyses suggested that changes in depression and anxiety were accounted for by changes in RNT.

Conclusions

The results indicate that mechanistic, targeted, and real-time technology-based solutions may provide scalable and effective interventions that advance the treatment of youth mental ill health.

BACKGROUND

Federally Qualified Health Centers (FQHCs) are an essential place for historically underserved patients to access health care, including screening for colorectal cancer (CRC), one of the leading causes of cancer death in the United States. Novel interventions aimed at increasing CRC screening completion rates at FQHCs are crucial.

OBJECTIVE

This study conducts user testing of a digital patient navigation tool, called eNav, designed to support FQHC patients in preparing for, requesting, and completing CRC screening tests.

METHODS

We recruited English- and Spanish-speaking patients (N=20) at an FQHC in New York City to user-test the eNav website (2 user tests; n=10 participants per user test). In each user test, participants engaged in a “think aloud” exercise and a qualitative interview to summarize and review their feedback. They also completed a baseline questionnaire gathering data about demographics, technology and internet use, medical history, and health literacy, and completed surveys to assess the website’s acceptability and usability. Based on participant feedback from the first user test, we modified the eNav website for a second round of testing. Then, feedback from the second user test was used to modify and finalize the eNav website.

RESULTS

Survey results supported the overall usability and acceptability of the website. The average System Usability Scale score for our first user test was 75.25; for the second, it was 75.28. The average Acceptability E-scale score for our first user test was 28.3; for the second, it was 29.2. These scores meet suggested benchmarks for usability and acceptability. During qualitative think-aloud exercises, in both user tests, many participants favorably perceived the website as motivating, interesting, informative, and user-friendly. Respondents also gave suggestions on how to improve the website’s content, usability, accessibility, and appeal. We found that some participants did not have the digital devices or internet access needed to interact with the eNav website at home.

CONCLUSIONS

Based on participant feedback on the eNav website and reported limitations to digital access across both user tests, we made modifications to the content and design of the website. We also designed alternative methods of engagement with eNav to increase the tool’s usability, accessibility, and impact for patients with diverse needs, including those with limited access to devices or the internet at home. Next, we will test the eNav intervention in a randomized controlled trial to evaluate the efficacy of the eNav website for improving CRC screening uptake among patients treated at FQHCs.
