Structural Validity and Reliability of the “oral Health Assessment Tool” Applied by Speech-language Therapists in a Population of Older Chilean People
Authors: Morales Camilo , Henríquez Felipe , Muñoz Sergio
Published: July 2022

Background: A good state of oral health allows people to communicate and eat. This topic is relevant in older people given its close relationship with their general health. At present, health challenges are directed at detecting and preventing oral disorders and are seen to exclusively by dentists, because the existing instruments can only be applied by them. However, speech-language therapists undergo similar training, which would allow them to collaborate in these processes. In this context, the Oral Health Assessment Tool (OHAT) is a detection instrument with good psychometric properties that is currently available for non-dental use. The objective of this study is the translation into Chilean Spanish of the OHAT and a structural validation of that version for application by these professionals. Materials and methods: A mixed qualitative-quantitative study was carried out. The OHAT instrument was adapted to Chilean Spanish and subsequently subject to structural validity and evaluation of internal consistency reliability, as well as a valuation of its reproducibility in 286 older people (166 female, 120 male) from different health contexts. Results: The cultural adaptation of the instrument proved to be semantically consistent with the original instrument. Its application was considered to be speedy and simple in the pre-test. The Confirmatory Factor Analysis evidenced the unidimensionality of the OHAT. In addition, the instrument shows good internal consistency and test-retest reliability.Conclusions: The OHAT instrument was considered to possess adequate structural validity and test-retest reliability properties. Its usefulness in the context of oral health disorders of this population in Chile is discussed.

Published: July 2022

The transcription factor hepatocyte nuclear factor 1β (HNF-1β) is essential for normal development of the kidney and other epithelial organs. In the developing mouse kidney, HNF-1β is required for the differentiation and patterning of immature nephrons and branching morphogenesis of the ureteric bud (UB). Here, we used ChIP-sequencing (ChIP-seq) and RNA sequencing (RNA-seq) to identify genes that are regulated by HNF-1β in embryonic mouse kidneys. ChIP-seq revealed that HNF-1β binds to 8,284 sites in chromatin from E14.5 mouse kidneys. Comparison with previous ATAC-seq and histone modification studies showed that HNF-1β binding peaks colocalized with open chromatin and epigenetic marks of transcriptional activation (H3K27 acetylation, H3K4 trimethylation, H3K4 monomethylation), indicating that the binding sites were functional. To investigate the relationship between HNF-1β binding and HNF-1β-dependent gene regulation, RNA-seq was performed on UB cells purified from wild-type and HNF-1β mutant embryonic kidneys. A total of 1,632 genes showed reduced expression in HNF-1β-deficient UB cells, and 485 genes contained nearby HNF-1β binding sites indicating that they were directly activated by HNF-1β. Conversely, HNF-1β directly repressed the expression of 526 genes in the UB. Comparison with snATAC-seq analysis of UB-derived cells showed that both HNF-1β-dependent activation and repression correlated with chromatin accessibility. Pathway analysis revealed that HNF-1β binds near 68 axon guidance genes in the developing kidney. RNA-seq analysis showed that Nrp1, Sema3c, Sema3d, Sema6a, and Slit2 were activated by HNF-1β, whereas Efna1, Epha3, Epha4, Epha7, Ntn4, Plxna2, Sema3a, Sema4b, Slit3, Srgap1, Unc5c and Unc5d were repressed by HNF-1β. RNAscope in situ hybridization showed that Efna1, Nrp1, Sema3c, Sema3d, Sema6a, and Slit2 were expressed in wild-type UB and were dysregulated in HNF-1β mutant UB. These studies show that HNF-1β directly regulates the expression of multiple axon guidance genes in the developing mouse kidney. Dysregulation of axon guidance genes may underlie kidney defects in HNF-1β mutant mice.
Macroeconomic Convergence in West African Monetary Zone
Authors: Ude Damian Kalu
Published: July 2022

This study has investigated the issues pertaining to the macroeconomic convergence in West Africa Monetary Zone (WAMZ) countries and the degree of compliance with both the primary and secondary convergence criteria laid down for WAMZ member countries. The study used panel data from 2000 to 2020. The study employed a log-t test for the convergence analysis for the primary and secondary criteria variables for WAMZ member states while comparing results from cointegration test for convergence to estimate all parameters of all equations simultaneously taking into consideration the correlations among the cross-sectional countries. The log-t test result suggests that all the primary criteria variables for convergence have converged. Result equally shows that all the secondary criteria variables have converged except for total national debt percentage of gross domestic product (GDP) which appears to be diverging among WAMZ countries. Therefore, member states of West African Monetary Zone should ensure that full convergence is attained in the nearest future in all the primary criteria variables by ensuring policy coordination and strict compliance of enabling macroeconomic policies. The study recommends the commencement of the WAMZ convergence objective of single currency after full convergence.
WITHDRAWN: Transport and combustion phenomena of methane flames in flow environments
Authors: Chen Junjie
Published: July 2022

Flame stabilization is a common problem in small-scale combustion systems. A fundamental understanding of the stabilization mechanisms of a flame within very small spaces is of both fundamental and practical significance. However, the transport and combustion phenomena of methane flames in flow environments remain unclear and warrant further study. This study relates to the transport and combustion phenomena of methane flames in flow environments. Computational fluid dynamics simulations are carried out to gain insights into the nature of the chemical reaction in flow environments. Computations are performed to predict combustion phenomena over wide temperature and concentration ranges. The factors affecting transport and combustion phenomena are determined for methane flames in flow environments. Particular focus is placed on determining essential factors that affect the transport and combustion phenomena of methane flames in flow environments. The results indicate that flame combustion is most prominent with fuels that have been premixed with an oxidant for the reaction. The process of diffusion is of great importance in flames. Physical processes that transfer mass and energy by diffusion or convection occur in gaseous combustion. In the absence of external forces, the rate of component diffusion depends upon the concentration of the constituents, pressure, and temperature changes, and on diffusion coefficients. The heat flux is proportional to the temperature gradient. Dilution of the burning mixture with an inert gas lowers the temperature and, consequently, the reaction rate. Great amounts of inert gas extinguish the flame, and the same result is achieved when substances that remove any of the active species are added to the flame. The principal quantitative characteristic of a flame is its normal, or fundamental, burning velocity, which depends on the chemical and thermodynamic properties of the mixture and on pressure and temperature, under given conditions of heat loss. Combustion proceeds primarily at temperatures close to the maximum the flame can achieve. Flame propagation is accounted for by heat energy transport from the combustion zone to the unburned mixture, which raises the temperature of the mixture. Both heat transport and diffusion of active particles must be considered essential for ignition.
WITHDRAWN: Thermal properties of carbon nanotubes using characterization techniques
Authors: Chen Junjie
Published: July 2022

Carbon nanotubes can exhibit unique ability to conduct heat. However, the effects of different factors on the thermal conductivity of carbon nanotubes are still poorly understood. Little research has been conducted to determine which parameters are important for high thermal conductivity. This study relates to the thermal properties of carbon nanotubes using characterization techniques. Carbon nanotubes were produced and characterized by scanning electron microscopy and Raman spectroscopy. The effects of different factors on the thermal conductivity of carbon nanotubes were investigated to understand the characteristics of thermal transport in the nanostructured material. The objective is to gain insight into the fundamental characteristics of thermal transport in carbon nanotubes. Particular emphasis is placed on the dependence of thermal conductivity on different factors, with an attempt to improve the heat conduction properties for carbon nanotubes. The results indicated that a single-walled carbon nanotube can be described as a long tube formed by wrapping a single graphene sheet into a cylinder with diameter of about one nanometer, the ends of which are capped by fullerene cages. The sidewalls of carbon nanotubes are made of graphene sheets consisting of neighboring hexagonal cells. Three different types of single-walled carbon nanotubes are distinctly characterized, named zigzag, armchair, and chiral. These structural variations result in differences in electrical conductivity and mechanical strength. Multi-walled carbon nanotubes are concentrically aligned single-walled carbon nanotube assemblies with different diameters. The distance between adjacent shells is about 0.34 nanometer. Multi-walled carbon nanotubes differ from single-walled carbon nanotubes not only in their dimensions, but also in their corresponding properties. The specific thermal conductivity decreases with increasing bulk density. The bulk density may be controlled to produce carbon nanotube films with high thermal conductivity. As for thermal properties, carbon nanotubes outperform diamond as the best thermal conductor. Applications of carbon nanotubes are aimed to make use of their unique properties to solve problems at the nanoscale.

Published: July 2022

The need for immersion oil becomes very important in carrying out various laboratory analyses with a microscope to clarify the image of objects with sharp imaging. To answer this need, research has been carried out to find an alternative to immersion oil by utilizing one of the typical Alor plants that grow a lot in dry areas, namely Kesambi. In this study, the results of the immersion oil test from Kesambi which was made in 2016 were compared with the results of the retest of the same oil in 2021 and compared with standard immersion oil to determine the quality of the immersion oil. In the existing stock of Kesambi immersion oil, physical properties analysis, GC-MS, and imaging of onion cells were carried out. The results showed that the comparison of the physical properties of Kesambi immersion oil which was analyzed in 2016 and the results of the re-analysis in 2021 showed that there was no significant difference based on the parameters of density, viscosity, refractive index, acid number, and aperture value. Results GC-MS in standard immersion oil only contained 49.68% benzyl benzoic acid and reanalyzed Kesambi immersion oil found palmitic acid 12.26%, oleic acid 46.46%, stearic acid 5.26% arachidic acid 13, 84%, and other spectra were detected as impurities. Although there were impurities and differences in fatty acid content between the standard immersion oil and the immersion oil from Kesambi that had been stored for five years, there was no difference in the imaging results of onion cells.
Distribution and diffusion thermodynamic characteristics of phosphorus at the interface between river sediment and water under the influence of artificial disturbance
Authors: Song Yujia , Song Shoufa , Huang Yan
Published: July 2022

Artificial disturbance affects the migration of phosphorus (P) at the interface between river sediments and water. In the present research, we sampled three sections of the Yitong River in Changchun City, China, in order to obtain representative samples of city, town, and rural reaches. Overlying water and sediment samples were obtained in September 2021 during the dry period. In our experiments, we determined the distribution of different forms of P, diffusion flux of P at the interface, as well as P adsorption parameters. The results showed that concentrations of four P species in the sediments followed the order: Ca-P > Fe-P > Acid extracted phosphorus > Alkali extracted phosphorus. The diffusion flux of -P in each reach was positive, showing that sediments were an important P source for the overlying water. The -P content in the interstitial water of sediments was significantly correlated with that in the overlying water. This indicated that P diffused into the overlying water in the form of -P under most circumstances. The adsorption parameters gradually decreased from upstream to downstream. These data indicated that potential for phosphorus release from downstream sediments was higher than that from upstream sediments. This likely occurred because, downstream, a greater artificial disturbance intensity is observed.
Distributed wastewater treatment offers an environmentally preferable alternative to conventional septic systems in Central Florida

Published: July 2022

Wastewater management is a critical issue globally. In Florida, the importance of this issue is heightened by the proximity to sensitive ecosystems. Distributed wastewater treatment units (DWTU) are a recent, state-approved alternative to septic system conversions to centralized sewer infrastructure. In this study, the performance of a DWTU was tested at a new residence in Lake Hamilton, FL. A monitoring well was installed downgradient of the DWTU absorption field to establish baseline groundwater conditions prior to occupation of the residence. The residence was occupied, after which groundwater, DWTU influent, and effluent samples were collected. Many effluent parameters significantly decreased compared to influent, including ammonia (NH3; 97%), total Kjeldahl nitrogen (TKN; 95%), total nitrogen (TN; 88%), the TN:TP ratio (84%), fecal coliforms (92%), carbonaceous biochemical oxygen demand (CBOD; 96%), and total suspended solids (TSS; 96%). In the groundwater, nutrient concentrations initially increased compared to the baseline data, but eventually decreased, demonstrating that the DWTU was effective at improving quality of wastewater effluent. These systems could be especially effective in sensitive areas where advanced wastewater treatment has been mandated or is needed.

Published: July 2022

Epilepsy is the most common chronic neurological disease, affecting approximately 65 million people worldwide, with mesial temporal lobe epilepsy (mTLE) being the most common type, characterized by the presence of focal seizures that begin in the hippocampus and subsequently generalize to structures such as the cerebral cortex. It is estimated that approximately 40% of patients with mTLE develop drug resistance (DR), whose pathophysiological mechanisms remain unclear. The neuronal network hypothesis is one attempt to understand the mechanisms underlying resistance to antiepileptic drugs (AEDs), since recurrent seizure activity generates excitotoxic damage and activation of neuronal death and survival pathways that in turn promote the formation of aberrant neuronal networks. This review addresses the mechanisms that are activated, perhaps as compensatory mechanisms in response to the neurological damage caused by epileptic seizures but that affect the formation of aberrant connections that allow the establishment of inappropriate circuits. On the other hand, glia seem to have a relevant role in postseizure plasticity, thus supporting the hypothesis of the neuronal network in drug-resistant epilepsy, which has been proposed for ELT.

Published: July 2022

High Resolution Melting (HRM) is a homogeneous, exceptionally incredible
innovation for single nucleotide polymorphism (SNP) genotyping, mutation scanning
and sequence scanning in DNA samples. HRM analysis works on the principle of
melting (dissociation) curve methodologies of Polymerase Chain Reaction (PCR)
empowered by the new accessibility of improved double-stranded DNA
(dsDNA)–binding dyes and next-generation real-time PCR instrumentation. The HRM
technology portrays samples of nucleic acids on the basis of their disassociation
behaviors and identifies the differences in even the short sequence in amplified PCR
products, just by direct melting. Samples are further distinguished according to the
length of their sequence, GC content and strand complementarity. Indeed, even a single
change in the base pair in the sequences of DNA samples causes differences in the
HRM curve. The difference in the melting curves of different genetic sequences at
distinct rates can be observed, detected and compared using these curves. Development
of the melting curves after HRM analysis is basically plotted with temperature on the X
axis and fluorescence on the Y axis, which resembles the real-time PCR amplification
curve but with the difference of temperature for cycle number. With the use of different
DNA dyes, high-end instrumentation and sophisticated analysis software, these
distinctions are detected.

Antecedentes y Objetivos: En la Sierra Norte de Puebla (SNP), México, el bosque mesófilo de montaña es el tipo de vegetación que alberga el mayor número de pteridofitas en el país; sin embargo, para esta zona aún faltan estudios sobre la riqueza de este grupo. El objetivo de este trabajo fue realizar el listado florístico de las licofitas y helechos de la SNP, y determinar la afinidad de especies entre los tipos de vegetación.Métodos: Se revisaron ejemplares herborizados del año 1900 al 2018, incluyendo colectas hechas por los autores. Se calculó la curva de acumulación de especies mediante índices no paramétricos, y el índice de biodiversidad taxonómica (IB, taxones/km2) con los resultados obtenidos y de estudios pteridoflorísticos de zonas aledañas a la SNP; se estimó el índice de similitud de Sorensen (IS) y se hizo un análisis de agrupamiento, para determinar la afinidad específica entre las vegetaciones. También se documentó el estado de conservación de los taxones.Resultados clave: Se registraron 253 especies, 12 variedades y un híbrido, circunscritos en 81 géneros y 29 familias; 44 taxones no se habían reportado antes para la zona, de estos, 14 son nuevos registros para el estado. El bosque mesófilo presentó la mayor riqueza (190 especies y 10 variedades). El IB de la SNP fue de 30.4 taxones/km2. El análisis de completitud mostró una tendencia a la asíntota, pero podría incrementar el número de especies (22-33%). La similitud de pteridofitas entre las vegetaciones fue baja (IS=0-0.52), el valor más alto ocurrió entre las selvas mediana perennifolia y subperennifolia.Conclusiones: La SNP concentra 69.8% de las pteridofitas del estado de Puebla, y resulta preponderante implementar proyectos de conservación, e incrementar las recolectas en los municipios menos explorados, sobre todo con bosque mesófilo de montaña.

Authors: Wan Ali Wan Nordiana , Ahmad A Ghafar
Published: July 2022

Heritage shophouses are the architectural asset that becomes a landmark of many heritage areas, particularly in major towns in Malaysia. This cultural heritage needs to be preserved or conserved to prolongs its life. However, there is still a need for in-depth study on the architectural part as to add knowledge about this heritage treasure. Thus, this paper tends to develop a definitive list of the architectural characters of the heritage shophouse façades according to its elements. The definitive list was outlined by referring and comparing data extracted from the local government reports, books, articles, and research undertaken by scholars in architecture and conservation. Furthermore, a fieldwork had been conducted at the Heritage Area of Ipoh involving 121 shophouses by using a checklist to support the secondary data. Thematic analysis was applied by sorting all architectural characters into five main categories of elements that include structural, building enclosure, opening, fenestration, and ornamentation. Later, a matrix taxonomy of architectural styles was developed to form an evaluation tool as an innovation to the existing inventory and documentation method for the heritage shophouses. The paper concludes that the concise data of architectural characters are significant to differentiate the styles of the heritage shophouse façade. Further research at other heritage areas in Malaysia should be conducted to gain more data of other architectural styles.

Published: July 2022

In urban vertical housing in Jakarta, air conditioning (AC) is mainly used to create comfort in units and spare residents from hazardous outdoor pollution. Residents in urban vertical housing, who have come from the surrounding multi-ethnic area, live in dense conditions. This situation inflicts conflicts of interest that affect indoor air quality (IAQ). This research develops a human dimension model for promoting indoor air quality in dense urban housing using the concept of sustainability, which is an environmental science approach. This study aims to conceptualize the effect of the human dimension in IAQ planning. The method is partial least squares-self equation modelling (PLS-SEM) analysis. The indicator variables of the human dimension related to indoor air quality are room quality, sociocultural factors, open space relief, environmental capacity, economic factors, and room maintenance. This result is a modified model of the fourth pillar of sustainability, according to Hawkes’ theory on housing planning. The variable human cultural dimensions are knowledge, perception, behaviour, and participation, which frame the sustainable development concept: the social dimension, environmental dimension, and economic dimension.

Published: July 2022

Currently, the main environmental concerns encountered by most countries are energy and its consumption. A green lifestyle and energy efficiency (EE) could reduce daily energy consumption. Nevertheless, low awareness and knowledge of EE prevent proper green lifestyle practices to save energy and the environment. Thus, the study aims to examine building occupants’ EE and energy conservation awareness and practices based on Islamic perspectives. The study objectives are to examine the level of EE awareness and practices among Malaysian building occupants and incorporate the potential of Islamic teachings from al-Quran concerning energy consumption and conservation in the EE awareness campaigns. The study used the qualitative research method, which involved a literature review, observation, and narrative study. As a result, the significant relevance of EE awareness and practices along with Islamic teachings is explained further in this study. Moreover, instilling knowledge, creating awareness and encouraging occupants to implement EE practices, which consequently reduce energy demand and energy consumption, hence, mitigating the detrimental environmental impacts. The study is crucial in raising public awareness of the Islamic perspectives linked with energy conservation and provides a framework for future development plans that embody EE elements aligned with Islamic teachings.

Georgetown, the capital of Penang Island, records the second highest density in Malaysia. On the other hand, those with lower economic status mostly live in low-cost, high-density vertical housing with indoor and outdoor environmental quality. Such housing conditions have severe implications on the residents’ comfort. Hence, this study adopted the mixed-method approach to assess indoor and outdoor air and lighting quality in high-rise low-cost housing. The qualitative approach was deployed to observe three low-cost high-rise housing in Penang while the second approach was quantitative data collected using a survey questionnaire distributed to households in the case study area. This study aims to identify the current environment indoor and outdoor lighting quality in low-cost high-rise housing. The three low-cost housing areas investigated in this study, namely, Taman Ampang Jaya (TAJ) (Seberang Jaya Utara (SPU) district), Halaman Kenanga (HK) (Daerah Timur Laut (DLT) district), and Idaman Seroja (IS) (Daerah Barat Daya (DBD) district), had more than 200 units. Resultantly, the three-housing had an average air and lighting quality, whereas the corridor indicated poor lighting, as well as foul and unhealthy air. Indoor and outdoor air quality and lighting in high-rise housing are related to the environment surrounding the site.

This study aims to determine and rank the factors influencing purchase decisions of green residential properties in Malaysia. The quantitative research approach was adopted in this study where the approach includes conducting surveys and analysing the quantitative data within green residential properties owners or residents with green certification mainly located in Penang and Selangor. Relative importance index is applied to data from a sample of 171 respondents through a purposive sampling. The main factors in influencing the green homebuyers’ decisions were found to be location factors followed by financial and neighbourhood and housing attributes. This study was the first to include green residential properties owners with green certification from Malaysian Green Building Index which focus only for green residential properties owners in Penang and Selangor as the sample of the study towards factors for influencing the purchase decision of green residential properties. Further development of empirical models could be developed and tested not only in other countries as well as to other types of green buildings. This study could provide best indicators for purchase decisions that could be embedded in the future green residential development. Stakeholders and policy makers could also provide incentive, recognition and take actions to increase awareness related to green development to internalise the medium-and long-term goals of green technology.

Differential scanning calorimetry was used to study the Co-C nanocomposite, which is an array of ultrathin carbon nanocages encapsulated cobalt nanoparticles. The activation energy of the α-β transformation of the nanocomposite and the value of its endothermic effect have been estimated. Thermal effect is much greater than those values ​​that correspond to the observation conditions for α-β transformations in massive cobalt samples. The idea was put forward that transitional transformation is assumed by a non-diffusion, massive mechanism.

Abstract - The research aimed to measure and evaluate the impact of intellectual capital and governance on organizational performance for a sample of universities in Sulaymaniyah. Where intellectual capital is considered one of the most important assets of the organization, it also helps in adding a competitive advantage and investing these assets in light of the mechanisms and principles of governance, which is reflected in achieving high levels of performance and providing services with high quality.
In order to achieve the objectives of the research and test its hypotheses, the primary and secondary data were relied upon and a questionnaire was designed. The two researchers used the statistical program (SPSS) to analyze the data.
During the research, it was found that there is a significant effect of intellectual capital on improving performance and raising the efficiency of organizations through the application of governance rules and the exploitation of intellectual resources and assets.
The two researchers also made a set of recommendations, the most important of which is to help teachers overcome weaknesses in their performance and enhance strengths by urging the research organizations to develop the capabilities of teachers and improve their performance through their participation in conferences, scientific seminars, and efficient and distinguished training programs

Published: July 2022

Background

Mobile apps are becoming increasingly popular, with 5.70 million apps available in early 2021. Smartphones can provide portable and convenient access to health apps. Here, we consider apps for people with one of the estimated 7000 rare conditions, which are defined as having an incidence of <1 in 2000. The needs of people with rare conditions are known to be different from those of people with more common conditions. The former may be socially isolated (not knowing anyone else who has the condition) and may not be able to find reliable information about the disorder.

Objective

The aim of this review is to search for apps developed specifically for people diagnosed with a rare disease and to assess them for quality using the Mobile App Rating Scale (MARS). We examine features that address 6 identified needs of people with a rare disorder and make recommendations for future developers.

Methods

Google Play Store (Android) and Apple App Store (iOS) were searched for relevant health-related apps specifically for rare diseases. The search included the names of 10 rare disease groups. App quality was determined using MARS, assessing app engagement, functionality, aesthetics, and information.

Results

We found 29 relevant apps (from a total of 2272) addressing 14 rare diseases or disease groups. The most common rare conditions addressed were cystic fibrosis (n=6), hemophilia (n=5), and thalassemia (n=5). The most common app features were web-based information and symptom trackers. The mean MARS score was 3.44 (SD 0.84). Lowest scores were for engagement.

Conclusions

Most apps provided factual and visual information, providing tools for self-monitoring and resources to help improve interactions during health consultations. App origin and quality varied greatly. Developers are recommended to consider ways to make appropriate apps more easily identifiable to consumers, to always include high-quality information, improve engagement, provide qualitative evaluations of the app, and include consumers and clinicians in the design.

Published: July 2022

Background

Children under 18 years of age account for approximately 1 in 3 internet users worldwide. Largely unregulated, the internet-based world is evolving rapidly and becoming increasingly intrusive. There is a dearth of objective research globally on children’s real-time experiences of the internet-based world.

Objective

This paper reports an objective methodology to study the nature and extent of children’s internet-based world, their engagement with it, and how this impacts their health and well-being.

Methods

A total of 180 year 8 students from 12 schools will be recruited into the study within the Wellington region of Aotearoa, New Zealand. Children use Zoom video teleconferencing software to record real-time, screen-shared internet-based content, for 4 consecutive days. Data on demographics, health and well-being, and attitudes and perceived behaviors in relation to the internet-based world are collected. Phone screen-time balances are retrieved. Data collection commenced in June 2021 and is anticipated to be completed in 2023.

Results

Recordings show children exploring diverse web-based settings and content, including personalized content curated by algorithms on platforms such as TikTok, YouTube, and Instagram. Preliminary analysis shows that the data can be used to study a wide range of topics. Behavioral Observation Research Interaction Software is being used to manually code recordings. Artificial Intelligence techniques are also being applied, including hashtag extraction, optical character recognition, as well as object, pattern, speech, and lyric recognition.

Conclusions

This novel methodology reveals the unique internet-based experiences of children. It is underpinned by a commitment to ensuring that their rights are protected. It seeks to provide concrete evidence on internet usage in this group and to facilitate appropriate political and societal action to effectively regulate the internet-based world to prevent harm to children.

Visualization of Traditional Chinese Medicine Formulas: Development and Usability Study (Preprint)
Authors: Wu Zhiyue , Peng Suyuan , Zhou Liang
Published: July 2022

BACKGROUND

Traditional Chinese medicine (TCM) formulas are combinations of Chinese herbal medicines. Knowledge of classic medicine formulas is the basis of TCM diagnosis and treatment and is the core of TCM inheritance. The large number and flexibility of medicine formulas make memorization difficult, and understanding their composition rules is even more difficult. The multifaceted and multidimensional properties of herbal medicines are important for understanding the formula; however, these are usually separated from the formula information. Furthermore, these data are presented as text and cannot be analyzed jointly and interactively.

OBJECTIVE

We aimed to devise a visualization method for TCM formulas that shows the composition of medicine formulas and the multidimensional properties of herbal medicines involved and supports the comparison of medicine formulas.

METHODS

A TCM formula visualization method with multiple linked views is proposed and implemented as a web-based tool after close collaboration between visualization and TCM experts. The composition of medicine formulas is visualized in a formula view with a similarity-based layout supporting the comparison of compositing herbs; a shared herb view complements the formula view by showing all overlaps of pair-wise formulas; and a dimensionality-reduction plot of herbs enables the visualization of multidimensional herb properties. The usefulness of the tool was evaluated through a usability study with TCM experts.

RESULTS

Our method was applied to 2 typical categories of medicine formulas, namely tonic formulas and heat-clearing formulas, which contain 20 and 26 formulas composed of 58 and 73 herbal medicines, respectively. Each herbal medicine has a 23-dimensional characterizing attribute. In the usability study, TCM experts explored the 2 data sets with our web-based tool and quickly gained insight into formulas and herbs of interest, as well as the overall features of the formula groups that are difficult to identify with the traditional text-based method. Moreover, feedback from the experts indicated the usefulness of the proposed method.

CONCLUSIONS

Our TCM formula visualization method is able to visualize and compare complex medicine formulas and the multidimensional attributes of herbal medicines using a web-based tool. TCM experts gained insights into 2 typical medicine formula categories using our method. Overall, the new method is a promising first step toward new TCM formula education and analysis methodologies.
