Design of Intelligent Warehouse Management System Based on MVC
Authors: Lu Ping , Liu Pingping , Xu Jiangtao
Published: July 2021

Aiming at the problems of single function, low service level and difficult to meet customers’ demand for warehousing business in warehouse management system, a collaborative filtering recommendation algorithm is proposed. The algorithm calculates the similarity between items by analyzing user’s consumption behavior records, finds similar items to ‘target user’s favorite items, recommends similar items to ‘target user’, and designs commodity recommendation function for customer preferences, so as to improve user satisfaction and commodity sales efficiency. In order to provide users with better service experience and make the system operators easy to use, it is proposed to use B / S architecture and MVC framework model to design four modules : user management, allocation management, warehouse information management and report management, and to establish the corresponding database for unified management. Finally, the intelligent warehouse management system with high user experience satisfaction and convenient background management operation is obtained.

Authors: Yılmaz V.
Published: July 2021

Water consumption and demand by persons vary from time to time and from location to location depending on countless factors, notably, population, socio-economic and climatic variables. Today, studies that create models of water consumption of persons, using numerous methods including artificial neural networks and regression models in this regard and ensure that ongoing projections are made. In this study, parameters affecting water consumption were examined within the scope of the study area, and the parameter reduction was realized with the help of Factor Analysis. Then, as a new method, the Band Similarity method was used together with the Artificial Bee Colony optimization algorithm, urban water demand models were produced and the temporal dependence of the relevant variables was examined. As a result of the study, it was seen that the Band Similarity method improved the results obtained with the optimization algorithm and helped to understand the temporal dependencies of the variables. The fact that the Band Similarity method, which was put forward for the first time in its field, worked successfully and produced results, can be said to be the main contribution of this study to existing knowledge.

Published: July 2021

Comparative analysis of solutions of Sedov’s problem of a point explosion in gas for the plane case, obtained by the analytical method and using the open software package of computational fluid dynamics OpenFOAM, is carried out. A brief analysis of methods of dimensionality and similarity theory used for the analytical self-similar solution of point explosion problem in a perfect gas (nitrogen) which determined by the density of uncompressed gas, magnitude of released energy, ratio of specific heat capacities and by the index of geometry of the explosion is given. The system of one-dimensional gas dynamics equations for a perfect gas includes the laws of conservation of mass, momentum, and energy is used. It is assumed that at the initial moment of time there is a point explosion with instantaneous release of energy. Analytical self-similar solutions for the Euler and Lagrangian coordinates, mass velocity, pressure, temperature, and density in the case of plane geometry are given. The numerical simulation of considered process in sonicFoam solver of OpenFOAM package built on the PISO algorithm was performed. For numerical modeling the system of differential equations of gas dynamics is used, including the equations of continuity, Navier-Stokes motion for a compressible medium and conservation of internal energy. Initial and boundary conditions were selected in accordance with the obtained analytical solution using the setFieldsDict, blockMeshDict, and uniformFixedValue utilities. The obtained analytical and numerical solutions have a satisfactory agreement.

Fair value measurement and its impact on audit fees: evidence in the Brazilian market
Authors: Bastos Edson Vinícius Pontes , Holtz Luciana , Santos Odilanei Morais dos
Published: July 2021

Objective: The purpose is to verify the impact of using the measurement at fair value on the audit fees, differentiating even the period before and after the adoption of IFRS 13 (CPC 46).
 Methodology: The research is quantitative, for testing the hypothesis raised, the multiple regression technique was used, with data available from companies listed in B3 for the period between 2010 and 2016.
 Results: The evidence indicates that the complexity and subjectivity of fair value is recognized by the audit firms, that is, audit firms recognize that fair value measurement implies more effort and that the associated audit risk rises, leading firms to charge of a risk premium for the provision of the service. However, it was not possible to confirm that auditors' fees increased after the adoption of IFRS13 (CPC 46).
 Contributions of study: Theoretical/methodological - The study contributes to understanding the impacts of adopting international accounting standards, in this specific case on audit fees. Social/management - Given the evidence that there is a higher audit cost associated with the greater complexity of information in a fair value environment, companies can develop mechanisms to minimize the uncertainty of the information to be audited.

The objective of this study was to evaluate the performance and economic indicators of baby goats region submitted to different feeding systems in the Semiarid. A total of 30 baby goats of breed Parda Alpina × without defined racial pattern (SPRD) with initial weight of 3.35 kg ± 0.65 kg and final weight of 12.3 kg ± 0.5 kg were used, distributed in a completely randomized design in three breastfeeding systems with ten replicates each: traditional system (with natural breastfeeding), intensive breastfeeding system without concentrated supplementation, and intensive breastfeeding with concentrated supplementation. Goats submitted to the intensive artificial feeding system without concentrated supplementation showed a similar weight gain (121 g/day) when compared to the goats submitted to the system of suckling with concentrated supplementation (126 g/day). The highest income was provided by the animals submitted to the intensive system of suckling with concentrate. The gross margin for the two centenarians was positive, that is, revenues are higher than the effective operating cost, allowing us to conclude that the activity is paying off and will survive, at least in the short term. The diet of kids using concentrate provided better dry matter intake, greater weight gain and consequently presented better economic indicators.

Published: July 2021

Histopathological and spermatogenesis classification by Johnsen is widely used in the germinal epithelium maturation analysis, besides identifying pathological alterations able to cause subfertility and even infertility. The aim of this study was to analyze cell-differentiation histopathological data and to correlate them with expression of PRM-1, TNP-2, 17β-HSD3, LHR, generic MHC-I, MIC-B, NC1 and NC3 genes, involved in bovine spermatogenesis using qRT-PCR from testicular parenchyma. Based on Johnsen’s criteria, the results showed normal spermatogenic activity in these animals, classified at 6, 7 and 8 scores. The qRT-PCR analysis expression showed that MHC-I (generic) gene was less expressed than all the other genes in evaluated scores (p < 0.05) and, PRM-1 and TNP-2 were the most expressed genes (p < 0.05). The PRM-1 gene expression was significantly higher than TNP-2 (p < 0.05). Comparing scores, 17β-HSD3 gene expression was lower (p < 0.05) in score 6 when compared to scores 7 and 8 animals. It was also observed that PRM-1 expression was lower in score 6 when compared to 7, as well as TNP-2 gene was less expressed in the score 6 (p < 0.05) when compared to 7 and 8 scores. Our results demonstrated that MHC I (generic), MIC-B, NC1, NC3, and LHR genes are poorly expressed in bovine testis, suggesting their marginal action on spermatogenesis. Instead, PRM-1, TNP-2, and 17β-HSD3 expression were higher, supporting the notion that these genes can act directly on the germ cells differential development during bovine spermatogenesis.

:

Although American traditional medicine (ATM) has been practiced for millennia, its
complex multi-target mechanisms of therapeutic action remain poorly understood. Animal models
are widely used to elucidate the therapeutic effects of various ATMs, including their modulation of
brain and behavior. Complementing rodent models, the zebrafish (Danio rerio) is a promising novel
organism in translational neuroscience and neuropharmacology research. Here, we emphasize the
growing value of zebrafish for testing neurotropic effects of ATMs and outline future directions of
research in this field. We also demonstrate the developing utility of zebrafish as complementary
models for probing CNS mechanisms of ATM action and their potential to treat brain disorders.

Introduction:

Intercapillary research in mathematics and other pure sciences areas has always helped
humanity quantify natural phenomena.

Materials & Method:

This article also contributes to which valency-based topological indices are implemented
on tetrahedral sheets of clay minerals. These indices have been used for a long time and are considered the most
powerful tools to quantify chemical graphs.

Results:

The atoms in the chemical compound and the bonds between the atoms are depicted as the graph’s
vertices and edges, respectively.

Conclusion:

The valency (or degree) of a vertex in a graph is the number of edges incident to that vertex. In this
article, various degree-based indices and their modifications are determined to check each types’ significance.
Prediction of lncRNA-disease Associations Based on Robust Multi-label Learning
Authors: Zhang Jiaxin , Sun Quanmeng , Liang Cheng
Published: July 2021

Background:

Long non-coding RNAs (lncRNAs) are nonprotein-coding transcripts of more
than 200 nucleotides in length. In recent years, studies have shown that long non-coding RNAs
(lncRNA) play a vital role in various biological processes, complex disease diagnosis, prognosis, and
treatment.

Objective:

Analysis of known lncRNA-disease associations and the prediction of potential lncRNA-disease associations are necessary to provide the most probable candidates for subsequent experimental validation.

Methods:

: In this paper, we present a novel robust computational framework for lncRNA-disease association
prediction by combining the ℓ1-norm graph with multi-label learning. Specifically, we first construct
a set of similarity matrices for lncRNAs and diseases using known associations. Then, both
lncRNA and disease similarity matrices are adaptively re-weighted to enhance the robustness via the ℓ1-
norm graph. Lastly, the association matrix is updated with a graph-based multi-label learning framework
to uncover the underlying consistency between the lncRNA space and the disease space.

Results:

: We compared the proposed method with the four latest methods on five widely used data sets.
The experimental results show that our method can achieve comparable performance in both five-fold
cross-validation and leave-one-disease-out cross-validation prediction tasks. The case study of prostate
cancer further confirms the practicability of our approach in identifying lncRNAs as potential prognostic
biomarkers.

Conclusion:

Our method can serve as a useful tool for the prediction of novel lncRNA-disease associations.

Authors: Yuan Chunying , Jiang Xuejian , Liu Man , Yang Sa , Deng Shuai , Hou Chunsheng
Published: July 2021

Objective:

In the absence of known clinical symptoms, viruses were considered to be the most probable key pathogens of honey bee. Therefore, the aim of this study was to investigate the prevalence and distribution of honey bee viruses in managed Apis mellifera and Apis cerana in China.

Methods:

We conducted a screening of 8 honey bee viruses on A. mellifera and A. cerana samples collected from 54 apiaries from 13 provinces in China using RT-PCR.

Results:

We found that the types and numbers of viral species significantly differed between A. mellifera and A. cerana. Black Queen Cell Virus (BQCV), Chronic Bee Paralysis Virus (CBPV), Apis mellifera filamentous virus (AmFV), and Kakugo virus (DWV-A/KV) were the primary viruses found in A. mellifera colonies, whereas Chinese Sacbrood Bee Virus (CSBV) and Sacbrood Bee Virus (SBV) were the primary viruses found in A. cerana. The percentage infection of BQCV and CSBV were 84.6% and 61.6% in all detected samples. We first detected the occurrences of Varroa destructor virus-1 (VDV-1 or DWV-B) and DWV-A/KV in China but not ABPV in both A. mellifera and A. cerana.

Conclusion:

This study showed that BQCV and CSBV are the major threat to investigated A. mellifera and A. cerana colonies.
Synthesis of 225Ac-PSMA-617 for Preclinical Use
Authors: Scott Peter James Henry , Dumond Alexandra Rae Sowa , Rodnick Melissa Elizabeth , Piert Morand Ruediger
Published: July 2021

Background:

The recent approval of radiopharmaceuticals for diagnosis and treatment
of cancer is ushering nuclear medicine into a new era of theranostics and alpha therapy using radiopharmaceuticals
labeled with 225Ac shows remarkable results in clinical trials. As such, reliable
methods for the synthesis and quality control of 225Ac-radiopharmaceuticals are needed.

Objective:

225Ac-PSMA-617 is being used for targeted alpha therapy in patients with prostate cancer,
and we had cause to synthesize the agent for preclinical use. However, technology transfer
proved cumbersome owing to the paucity of information available on synthesizing and analyzing
225Ac-radiotherapeutics. To address this need, we describe a straightforward synthesis of 225Ac-PSMA-
617 as well as suitable approaches for quality control analysis using standard equipment in a
modern PET Center.

Methods:

PSMA-617 precursor was dissolved in 25 μL metal-free water (0.67 mg/mL) and combined
with 500 μL 0.05M Tris buffer, pH 9. Actinium stock solution (~65 μCi in 15 μL) was added
and the reaction was heated at 120°C for 40-50 min. The reaction was cooled and 0.6 mL gentisic
acid solution (4 mg/mL in 0.2 M NH4OAc) was added. To formulate the dose for injection, sterile
saline, USP (8 mL) was added and the pH was adjusted by the addition of 100 μL 0.05 M Tris buffer
(pH 9) to give a final pH of ~7.2. The final solution was filtered using a 0.22 μm GV sterile filter
into a sterile dose vial. Radiochemical purity was determined by radio-TLC (eluent: 50mM
Sodium Citrate, pH 5), and plates were analyzed using an AR2000 scanner.

Results:

The method provided 225Ac-PSMA-617 in high radiochemical yield (57 ± 3 μCi, >99%)
and radiochemical purity (98 ± 1%), formulated for preclinical studies (9 mL, pH = 7.2), n=3.

Conclusion:

A straightforward synthesis of 225Ac-PSMA-617 is described that will facilitate production
for (pre)clinical studies. The approach could also be applicable to the synthesis of other alpha
radiotherapeutics incorporating 225Ac.

Identification of Flavonoids as Potent Inhibitors Against MERS-CoV
3C-like Protease
Authors: Javanshir Shahrzad , Abdi Fatemeh
Published: July 2021

:

In 2012, a coronavirus was isolated from a patient with severe pneumonia. This betacoronavirus,
which appeared in Saudi Arabia, was named Middle East Respiratory Syndrome Coronavirus
(MERS-CoV). MERS-CoV is the sixth identified coronavirus that has the ability to infect
humans. The Middle East respiratory syndrome-coronavirus (MERS-CoV) is a zoonotic pathogen
transmitted between animals and humans. To date, MERS-CoV is responsible for an epidemic that
is still ongoing, but limited to the Arabian Peninsula, with a total number of more than 2000 cases
identified and a mortality rate of around 35%. The largest outbreaks of human-to-human transmission
were reported in Jeddah in 2014 and South Korea in 2015. This infection causes a high mortality
rate and no vaccine or medical countermeasures are currently available. Currently, no specific
treatment or vaccine is available against this virus. The current challenge is to contain the epidemic
and continue research efforts to develop a vaccine and a treatment. Certain flavonoids inhibit the replication
of viral RNA and have therapeutic potential against viruses and bacteria. Therefore, it is
suggested that flavonoids with these characteristics can be used as models to develop potent inhibitors
of MERS-CoV. This work reviews current knowledge and provides an update on MERS-CoV
and MERS-CoV 3Clpro virology, epidemiology, clinical features, and the use of flavonoids as potential
inhibitors and therapeutic agents for MERS-CoV, and MERS-CoV 3Clpro. This review tries
to elucidate the structure-activity relationships (SAR) of varied polyphenols against MERS-CoV
3C-like protease (3Clpro).

Published: July 2021

O Exame Nacional de Desempenho dos Estudantes (ENADE) é uma importante ferramenta de avaliação do ensino superior brasileiro. A prova, aplicada anualmente aos concluintes, segmentados por áreas de ensino, é composta de questões de formação geral e de conhecimentos específicos. As questões de formação geral têm como objetivo abordar aspectos éticos, humanísticos e de cidadania, bem como a capacidade de codificar e decodificar diferentes realidades. Esta investigação tem como objetivo analisar a prova de formação geral do ENADE do ano de 2017, assim como os diferentes fatores relacionados ao desempenho dos estudantes. Os microdados disponibilizados pelo Ministério da Educação foram analisados utilizando o software Stata 16 e correlacionados com as características das dez questões de formação geral, considerando o tema, a ação esperada e o texto base. Dados relativos a 449.527 provas foram analisadas. A média da nota nas questões discursivas foi de 53.84 e na objetiva de 49.93, com média final neste componente de 51.49. A análise dos dados revelou um desempenho superior entre: estudantes do sexo masculino; de instituições federais; de turno matutino e da região sudeste do país. Observou-se um índice de erro maior entre as questões que apresentam tabelas e gráficos. As variações no desempenho dos alunos nas questões de formação geral permitem compreender a diversidade e a pluralidade de fatores envolvidos no sucesso acadêmico em um sistema de ensino de dimensões continentais explicitando o impacto da desigualdade social, bem como o contraste de realidades de ensino existentes no país.

Published: July 2021

O presente estudo visou compreender o modo como os professores portugueses se adaptaram aos contextos de ensino à distância face à pandemia da COVID-19. Do ponto de vista metodológico, realizou-se um estudo quantitativo, de natureza extensiva, com o recurso a um inquérito por questionário online, ao qual responderam 2369 professores de todos os níveis de ensino. Os resultados obtidos mostram que os participantes tiveram que lidar com um conjunto complexo de dificuldades relacionado com o trânsito abrupto para um “ensino remoto de emergência”, o que implicou a criação de condições de acesso aos alunos, à reorganização da escola e do trabalho docente, à adaptação do processo de ensino e aprendizagem e ao domínio de diversas plataformas e ferramentas para interagir com os alunos. Embora prevaleça uma perceção positiva da capacidade das escolas e dos professores, sobretudo na valorização de recursos endógenos e da colegialidade, ressaltam os efeitos de sobrecarga de trabalho, stress, ansiedade e esgotamento, bem como a incapacidade de garantir uma resposta universal e inclusiva.
Structural-geomorphological aspects of the Petrinja earthquake M6.2 (Croatia) - preliminary considerations
Authors:   University of Zagreb, Faculty of Science, Department of Geography, Zagreb, Croatia, Bočić Neven
Published: July 2021

A strong earthquake of magnitude 6.2 with the epicentre near the town of Petrinja occurred on December 29th, 2020 in the fault zone of the right strike-slip Pokupsko Fault in Croatia. The aim of this study was to determine if there are geomorphological indicators of active tectonics in this area. General morphometric methods based on a digital elevation model with a resolution of 10 m were used. Geomorphological indicators of active tectonics were also determined based on topographic maps and hillshade relief. All the collected data were used to reconstruct the traces of the main morpholineaments on the surface and to determine the main morphostructures. It was found that the central part of the studied area, Hrastovička Gora, has morphological features possibly corresponding to a pop-up structure (positive flower) and that it consists of two separate morphostructures. They are separated from each other by an east-west oriented morpholineament, which is a possible segment of the Pokupsko Fault. Comparison of the collected results with the data on the location of the epicentres of the Petrinja series earthquakes of magnitude 4.0 and higher, which occurred in the period from December 28th, 2020 to March 3rd, 2021, indicates the possibility that these earthquakes were related to this restraining bending zone of the right horizontal Pokupsko Fault, which should be studied in more detail in the future.

Published: July 2021

In Croatia, as elsewhere, significant changes have occurred in the landscape over time, due to changes in land use, climate change, and general anthropogenic activities. Accordingly, the need for deeper and more intensive understanding of landscape properties has arisen, in order to ensure adequate land management and protection. The aim of this study is to give an overview of the state of scientific landscape research in Croatia, and determine the stakeholders, methodologies, various research topics, and degree of research and knowledge regarding Croatia’s landscapes. Over the past decade, there has been an increased interest in landscape research, with two clear landscape research approaches emerging: geographic approach and (landscape) architecture approach, that differ in terms of the issues examined, methodologies applied, and spatial context.
Placemaking, local community and tourism
Authors:   Institute for Tourism, Zagreb, Croatia, Vodanović Lukić Ives
Published: July 2021

The challenges of modern tourism development increasingly indicate the need for new approaches based on the creative use of intangible assets and heritage, and a more harmonious relationship between the local community and tourists. Placemaking is one such approach, which goes to the core of what builds places and local communities. This paper looks at the evolution of the concept, and its approaches and definitions. Among the tools of placemaking, tangible (physical design), intangible (mental images), and mixed approaches are recognized. The examples in this paper have been selected mainly from tourism and community development studies. Quality placemaking leads to the development of a sense of place, increases social cohesion, and stimulates the long-term regeneration of public spaces, which contributes to tourism attractiveness. In this light, the concept of placemaking can serve as a useful analytical category for more systematic research on spatial transformations and as a development tool in strategic tourism planning.

The article presents the results of research of the specifics of second homes as a consequence of accelerated tourism development in the Municipality of Neum in Bosnia and Herzegovina. This is a phenomenon which, primarily due to insufficient data, has not been scientifically researched in more detail. Based on secondary data collected from scant relevant sources, the authors analysed the available data regarding the number of holiday homes/apartments as well as the structural characteristics of holiday home owners. The phenomenon of second homes was analysed from the point of view of its development in Neum, as the only urban-type settlement within the municipality, and in rural settlements in its hinterland. The research showed the expansion of second homes from the narrow coastal zone into the interior and the concentration of holiday home owners in neighbouring municipalities and larger urban centres of Bosnia and Herzegovina, as well as in nearby areas of Dalmatia. The process of internationalisation was also analysed, as a large number of second homes are owned by foreign citizens, primarily those from neighbouring Croatia.

This paper examines sports, cultural, historical, and urban geography to analyse hodonyms (names of streets and squares) and ergonyms (names of hospitality establishments) located in the proximity of sports centres. The research examines whether there is a link between the hodonyms and ergonyms associated with sports and the location of sports facilities. The starting point of this research was the assumption that spatial proximity influences the motivation for naming streets, squares, and hospitality establishments. Accordingly, this paper approaches the concept of sports in the urban landscape from a spatial aspect. Case studies were conducted in the two largest cities of the Republic of Croatia: the capital city Zagreb, and Split. The main methodological approach used in the analysis of data was statistical and interpretative. The research showed that there is a degree of association between hodonyms and ergonyms and the location of sports facilities. Sports transform and shape the urban landscape, not only the sports landscape (in the form of infrastructure), but also other parts of the city.

The paper presents the results of a numerical and experimental study of an acoustic phase-shifter based on a chain of rectangular Helmholtz resonators. Phase regulation of the transmitted acoustic wave is made by simultaneously changing the resonators volumes with the stepper motor. As a result of the experiment it was found that the developed acoustic phase-shifter allows to manipulate the wave phase within the range of 0 - 2π in the frequency range of 2000 - 2500 Hz. The transmittance factor is not less than 0.7. The phase-shifter can be used as a unit cell of tunable acoustic metasurface.

Published: July 2021

Background

The COVID-19 outbreak has induced negative emotions among people. These emotions are expressed by the public on social media and are rapidly spread across the internet, which could cause high levels of panic among the public. Understanding the changes in public sentiment on social media during the pandemic can provide valuable information for developing appropriate policies to reduce the negative impact of the pandemic on the public. Previous studies have consistently shown that the COVID-19 outbreak has had a devastating negative impact on public sentiment. However, it remains unclear whether there has been a variation in the public sentiment during the recovery phase of the pandemic.

Objective

In this study, we aim to determine the impact of the COVID-19 pandemic in mainland China by continuously tracking public sentiment on social media throughout 2020.

Methods

We collected 64,723,242 posts from Sina Weibo, China’s largest social media platform, and conducted a sentiment analysis based on natural language processing to analyze the emotions reflected in these posts.

Results

We found that the COVID-19 pandemic not only affected public sentiment on social media during the initial outbreak but also induced long-term negative effects even in the recovery period. These long-term negative effects were no longer correlated with the number of new confirmed COVID-19 cases both locally and nationwide during the recovery period, and they were not attributed to the postpandemic economic recession.

Conclusions

The COVID-19 pandemic induced long-term negative effects on public sentiment in mainland China even as the country recovered from the pandemic. Our study findings remind public health and government administrators of the need to pay attention to public mental health even once the pandemic has concluded.

Published: July 2021

BACKGROUND

Respiratory sounds have been recognized as a possible indicator of behavior and health. Computer analysis of these sounds can indicate characteristic sound changes caused by COVID-19 and can be used for diagnostics of this illness.

OBJECTIVE

The aim of the study is to develop 2 fast, remote computer-assisted diagnostic methods for specific acoustic phenomena associated with COVID-19 based on analysis of respiratory sounds.

METHODS

Fast Fourier transform (FFT) was applied for computer analysis of respiratory sound recordings produced by hospital doctors near the mouths of 14 patients with COVID-19 (aged 18-80 years) and 17 healthy volunteers (aged 5-48 years). Recordings for 30 patients and 26 healthy persons (aged 11-67 years, 34, 60%, women), who agreed to be tested at home, were made by the individuals themselves using a mobile telephone; the records were passed for analysis using WhatsApp. For hospitalized patients, the illness was diagnosed using a set of medical methods; for outpatients, polymerase chain reaction (PCR) was used. The sampling rate of the recordings was from 44 to 96 kHz. Unlike usual computer-assisted diagnostic methods for illnesses based on respiratory sound analysis, we proposed to test the high-frequency part of the FFT spectrum (2000-6000 Hz).

RESULTS

Comparing the FFT spectra of the respiratory sounds of patients and volunteers, we developed 2 computer-assisted methods of COVID-19 diagnostics and determined numerical healthy-ill criteria. These criteria were independent of gender and age of the tested person.

CONCLUSIONS

The 2 proposed computer-assisted diagnostic methods, based on the analysis of the respiratory sound FFT spectra of patients and volunteers, allow one to automatically diagnose specific acoustic phenomena associated with COVID-19 with sufficiently high diagnostic values. These methods can be applied to develop noninvasive screening self-testing kits for COVID-19.
Methods for Human-Centered eHealth Development: Narrative Scoping Review (Preprint)

Published: July 2021

BACKGROUND

Thorough holistic development of eHealth can contribute to a good fit among the technology, its users, and the context. However, despite the availability of frameworks, not much is known about specific research activities for different aims, phases, and settings. This results in researchers having to reinvent the wheel. Consequently, there is a need to synthesize existing knowledge on research activities for participatory eHealth development processes.

OBJECTIVE

The 3 main goals of this review are to create an overview of the development strategies used in studies based on the CeHRes (Center for eHealth Research) Roadmap, create an overview of the goals for which these methods can be used, and provide insight into the lessons learned about these methods.

METHODS

We included eHealth development studies that were based on the phases and/or principles of the CeHRes Roadmap. This framework was selected because of its focus on participatory, iterative eHealth design in context and to limit the scope of this review. Data were extracted about the type of strategy used, rationale for using the strategy, research questions, and reported information on lessons learned. The most frequently mentioned lessons learned were summarized using a narrative, inductive approach.

RESULTS

In the included 160 papers, a distinction was made between overarching development methods (n=10) and products (n=7). Methods are used to gather new data, whereas products can be used to synthesize previously collected data and support the collection of new data. The identified methods were focus groups, interviews, questionnaires, usability tests, literature studies, desk research, log data analyses, card sorting, Delphi studies, and experience sampling. The identified products were prototypes, requirements, stakeholder maps, values, behavior change strategies, personas, and business models. Examples of how these methods and products were applied in the development process and information about lessons learned were provided.

CONCLUSIONS

This study shows that there is a plethora of methods and products that can be used at different points in the development process and in different settings. To do justice to the complexity of eHealth development, it seems that multiple strategies should be combined. In addition, we found no evidence for an optimal single step-by-step approach to develop eHealth. Rather, researchers need to select the most suitable research methods for their research objectives, the context in which data are collected, and the characteristics of the participants. This study serves as a first step toward creating a toolkit to support researchers in applying the CeHRes Roadmap to practice. In this way, they can shape the most suitable and efficient eHealth development process.

BACKGROUND

Cognitive impairment and dementia are some of the most important health challenges we face today. Almost 60% of people with dementia live in low-and middle-income countries, such as Colombia.

OBJECTIVE

The aim of this study was to evaluate the association between access, capacity to use and frequency of using with cognitive impairment among older adults in Colombia.

METHODS

This is a secondary analysis from the SABE (from its initials in Spanish: Salud, Bienestar & Envejecimiento) Colombia survey conducted in 2015. Access to technology, its usage and knowing how to use it were assessed using self-report. Cognitive function was assessed with the Minimental State Examination (MMSE) Folstein in its complete version (0-30). We retrospectively investigated the association between access, capacity to use and frequency of using with cognitive impairment among older adults in Colombia.

RESULTS

24.37% (n=5,774) of the interviewed older adults had access to computers and only 15% (n=3,743) to the internet. However, of the 23,694 participants only 8.6% (n=2,038) used computers and 5.85% (n=1,387) used the internet. The multivariate analysis showed that it was more likely to have cognitive impairment in the group that did not have access, did not use nor knew how to use technology than in the group that had access, knew how to use it and used it frequently (OR 26.38, CI 95%: 16.07 – 43.28 p < 0.001).

CONCLUSIONS

Our results share common points with previous studies stablishing an association between technology use and cognition and suggest that technology is one of the tools which could help carrying out the needed prevention, intervention and care.
