Authors: Yu Jian
Published: September 2024

Blockchain technology provides a technical solution for the challenges faced by e-government, such as low efficiency, excessive energy consumption, and lack of trust mechanisms. It can promote the establishment of a more efficient and high-quality government service system, thereby enhancing the public trust of the government. Although blockchain technology provides theoretical innovation to traditional governance structures with its decentralization, consensus mechanisms, and enhanced trust, its impact and ability to transform existing governance structures still have limitations in practical applications. Based on an in-depth analysis of the concept and application boundaries of blockchain, this article explores its value in the field of e-government. At the same time, it systematically proposes strategic suggestions to promote the development of blockchain technology in the field of e-government from multiple aspects such as institutional construction, technical standardization, and professional talent cultivation, in response to its limitations and application risks. By accelerating technology research and development and standard construction, strengthening high-level promotion, optimizing promotion competition mechanisms, and conducting rooted research, the application and promotion of blockchain in government governance can be accelerated, laying a solid foundation for building a future intelligent and transparent government service model.

Authors: Engin Onur , Kızılırmak Karataş Ayşe Sezgi , Taşpınar Betül , Taşpınar Ferruh
Published: September 2024

Background

YouTube has emerged as an important source for obtaining information regarding health issues.

Objective

The study aimed to assess the reliability and quality of facial paralysis exercise videos that are accessible on the YouTube platform.

Methods

The investigation was carried out on Youtube, utilizing the keyword “facial paralysis exercises”. We listed the first 100 videos based on relevancy. The quality and reliability of the videos were assessed using DISCERN, the Journal of the American Medical Association (JAMA) Benchmark Criteria, the Global Quality Scale (GQS), and the Video Power Index (VPI).

Results

Out of 100 studies, we excluded 52 and included the remaining 48. The scores we obtained for the videos were as follows: DISCERN Quality (2.92±0.91), DISCERN Total (39.16±6.75), JAMA (2.09±0.55), and GQS (3.00±0.89). Our study also revealed that videos uploaded by healthcare professionals had significantly higher DISCERN total, JAMA and VPI scores compared to those uploaded by non-healthcare professionals ( p = 0.018, 0.001 and 0.023, respectively). Additionally, we observed a positive and statistically significant correlation between the DISCERN quality score, total score, JAMA, and video features.

Conclusion

The facial paralysis exercise videos were determined to be of medium to low quality. Higher-quality videos need to be produced.

BACKGROUND: Hispanics are a significant demographic in the U.S., with diverse cultures and languages. Assessing cognition in this group is complex as cultural and linguistic factors have been found to affect test performance. OBJECTIVE: To generate normative data on the World Health Organization-University of California Los Angeles Auditory Verbal Learning Test (WHO-UCLA AVLT) in a sample of Spanish-speaking Hispanics residing in the U.S. METHODS: The sample included 245 Spanish-speaking individuals aged 18–80 across the U.S. (California, Connecticut, Florida, Indiana, New Jersey, Oregon, Virginia, and Wisconsin). Participants were administered the WHO-UCLA AVLT as part of a comprehensive neuropsychological battery. A Bayesian regression approach was used to estimate normative data, including covariates found to be important for predicting performances on measures of learning and memory. RESULTS: Bayesian models showed a logarithmic link between education and all WHO-UCLA AVLT trials, except recognition. For delayed recall, increased Spanish proficiency benefited women’s performance exclusively. Time in the U.S. was a significant predictor for total recall, indicating worse performance with longer residency. CONCLUSION: Recognizing cultural factors like language proficiency and duration of U.S. residence is essential for accurately evaluating cognitive function among Spanish-speaking Hispanics. This research emphasizes the importance of accounting for cultural nuances in developing norms for neuropsychological assessments, thereby improving their relevance and effectiveness in diverse communities.
Measuring the informal sector through mixed surveys: Past experiences and challenges ahead
Authors: Roubaud François
Published: September 2024

While in developing countries around 50% of total employment are informal sector jobs, and much more among the poorest, its statistical measurement is a major issue. Having long remained a black hole of national statistical systems, sound methodologies have been developed to measure the informal sector in its different dimensions (employment, production, and more broadly articulation with the rest of the economy) in a reliable manner. Taking stock on nearly four decades of experiences accumulated around the world, this article presents a system of original surveys, specially designed for this objective: the Informal Sector Mixed (households-businesses) Surveys (ISMSs). After exposing their theoretical principles, the paper addresses the main challenges of implementation in the field, detailing their advantages and limitations. In particular, we question the compatibility of ISMSs with the recommendations of the new Resolution concerning statistics on the informal economy, adopted in 2023 during the 21st International Conference of Labor Statisticians. We also identify avenues to address a certain number of challenges that still arise with this type of survey, both in the methodological field and on the institutional level. We illustrate our discussion with a set of selected empirical results drawn from surveys conducted in various contexts.
A survey on SPARQL query relaxation under the lens of RDF reification
Authors: Fakih Ginwa , Serrano-Alvarado Patricia
Published: September 2024

Query relaxation has been proposed to cope with the problem of queries that produce none or insufficient answers. The goal is to modify these queries to be able to produce alternative results close to those expected in the original query. Existing approaches querying RDF datasets generally relax the SPARQL query constraints based on logical relaxations through RDFS entailment and RDFS ontologies. Techniques also exist that use the similarity of instances based on resource descriptions. These relaxation approaches defined for SPARQL queries over RDF triples have proved their efficiency. Nevertheless, significant challenges arise for query relaxation techniques in the presence of statement-level annotations, i.e., RDF reification. In this survey, we overview SPARQL query relaxation works with a particular focus on issues and challenges posed by representative RDF reification models, namely, standard reification, named graphs, n-ary relations, singleton properties, and RDF-Star.

Published: September 2024

BACKGROUND: Heart disease represents the leading cause of death globally. Timely diagnosis and treatment can prevent cardiovascular issues. An Electrocardiograms (ECG) serves as a diagnostic tool for identifying heart difficulties. Cardiovascular Disease (CVD) often gets identified through ECGs. Deep learning (DL) garners attention in healthcare due to its potential in swiftly diagnosing ECG anomalies, crucial for patient monitoring. Conversely, automatic CVD detection from ECGs poses a challenging task, wherein rule-based diagnostic models usually achieve top-notch performance. These models encounter complications in supervision vast volumes of diverse data, demanding widespread analysis and medical capability to ensure precise CVD diagnosis. OBJECTIVE: This study aims to enhance cardiovascular disease diagnosis by combining symptom-based detection and ECG analysis. METHODS: To enhance these experiments, we built a novel automated prediction method based on a Feed Forward Neural Network (FFNN) model. The fundamental objective of our method is to develop the accuracy of ECG diagnosis. Our strategy employs chaos theory and destruction analysis to combine optimum deep learning features with a well-organized set of ECG properties. In addition, we use the constant-Q non-stationary Gabor transform (CQNGT) to convert one-dimensional ECG data into a two-dimensional picture. A pre-trained FFNN processes this image. To identify significant features from the FFNN output that correspond with the ECG data, we employ pairwise feature proximity. RESULTS: According to experimental findings, the suggested system, FFNN-CQNGT, surpasses other state-of-the-art systems in terms of precision of 94.89%, computational efficiency of 2.114 ms, accuracy of 95.55%, specificity of 93.77%, and sensitivity of 93.99% and MSE 40.32%. CONCLUSION: Contributing an automated ECG-based DL system based on FFNN-CQNGT for early-stage cardiovascular disease identification and classification holds great potential for both patient care and public health.

Authors: Lin Chunqin , Huang Yanru , Lin Qiansen
Published: September 2024

BACKGROUND:

Tonsillectomy and/or adenoidectomy can treat children with obstructive sleep apnea/hypopnea syndrome (OSAHS).

OBJECTIVE:

This study investigated the effects of tonsillectomy and/or adenoidectomy on cognitive function and brain structure in children with OSAHS.

METHODS:

This study included 40 obstructive sleep apnea/hypopnea syndrome children and 40 healthy children. The cognitive function and brain structure changes of OSAHS children before and after surgery and 40 healthy children were evaluated by the Swanson, Nolan, and Pelham Rating Scale (SNAP-IV) and the Integrated Visual and Auditory Continuous Performance Test (IVA-CPT), as well as brain resting-state fMRI functional magnetic resonance imaging (rs-fMRI).

RESULTS:

Children with OSAHS showed higher Swanson, Nolan, and Pelham Rating Scale and lower Integrated Visual and Auditory Continuous Performance Test scores than healthy peers, indicating cognitive impairment. Post-surgery, there was a significant improvement in cognitive function, evidenced by decreased Swanson, Nolan, and Pelham Rating Scale and increased Integrated Visual and Auditory Continuous Performance Test scores. Compared to healthy children, OSAHS children displayed altered ReHo values in certain brain regions, such as decreased values in the right angular gyrus, right precuneus, left parahippocampal gyrus, and left middle frontal gyrus, but increased values in the right posterior cerebellum. After surgery, ReHo values increased in regions like the right precuneus, right temporal lobe, right posterior cingulate gyrus, and left limbic lobe, suggesting neurological changes associated with treatment.

CONCLUSIONS:

Children with obstructive sleep apnea/hypopnea syndrome had cognitive impairment and abnormal changes in multiple brain regions. Tonsillectomy and/or adenoidectomy could improve cognitive function and contribute to the reconstruction of brain function and structure in children with obstructive sleep apnea/hypopnea syndrome.
Effects of using multi-category web pages on rank estimation of Google search engine results page
Authors: Almadhoun Mohamed D. , Malim Nurul Hashimah Ahamed Hassain
Published: September 2024

It is essential to use search engines to get the needed information. A search engine uses result matching to match the user’s query with appropriate web pages. Users see the search results in a certain order based on how they are ranked. A website or web page may be made better using search engine optimization (SEO), which will increase the amount of organic traffic it receives from search engines. If we can’t manage efficient SEO techniques to rank at the top of organic search results, a lot of money will be spent on sponsored adverts for certain keywords. The process of building rank estimate algorithms for search engine results pages (SERP) or applying data analysis to find the best SEO tactics has been employed in several research projects. The datasets of existing studies were undiversified since they only included web pages from one or a small number of categories. This research will improve rank estimation algorithms by using multi-category web pages in the training datasets and will provide demonstrations of improvement on SERP rank estimation algorithms for English web pages. Since Google receives more than 90% of all internet search submissions, scraping will be used there. For the chosen web pages, a collection of on-page SEO variables will be retrieved. The methodology starts with choosing a set of search terms and scraping search engines, then crawling SERP web pages to extract certain SEO criteria from the contents of web pages, and lastly getting to data preprocessing. Various machine learning techniques were used to compare performance and choose the optimal approach. The main finding of research is the enhancement of SERP rank estimation by more than 25% on performance with the proposed dataset improvements for building models.

Aim: to present a series of case reports of vitreous cysts and to discuss the diagnostic and management strategies employed in each case. Patients and Methods: a total of five patients with solitary vitreous cysts associated with various degenerative eye diseases were examined. All patients underwent a standard ocular examination and enzyme immunoassay to detect antibodies against Toxoplasma, Taenia solium, and Echinococcus. The followup period spanned a range of six to 18 months. Results: two patients exhibited unilateral vitreous cysts in association with pigmentary retinal degeneration. Published data indicate that this combination is the most prevalent. Two patients exhibited a vitreous cyst concomitant with degenerative myopia, and in one case, a rhegmatogenous retinal detachment was identified in the eye with the cyst. The potential etiology of these cysts is the migration of the retinal pigment epithelium into the vitreous, particularly during the formation of retinal tears. In one case, bilateral vitreous cysts were identified in conjunction with agerelated macular degeneration. To the best of our knowledge, this represents the inaugural description of this association. Throughout the observation period, the dimensions and location of the cysts remained consistent, and no additional discomfort was observed. Accordingly, we proceeded with the follow-up. Conclusion: in the majority of cases, vitreous cysts are benign and do not necessitate intervention. However, in instances where a cyst is situated in close proximity to the visual axis, it can potentially lead to visual impairment. In such cases, argon or Nd:YAG laser cystotomy or cyst removal via posterior pars plana vitrectomy may be indicated. It is imperative to differentiate vitreous cysts from other conditions that may present with similar symptoms, such as ocular toxoplasmosis, cysticercosis, echinococcosis, and pigmentary tumors. KEYWORDS: cyst, vitreous body, pigmentary retinal degeneration, toxoplasmosis, cysticercosis, echinococcosis.

Published: September 2024

Understanding the patterns and drivers of viral prevalence is of key importance for understanding pathogen emergence. Over the last decade, metagenomic sequencing has exponentially expanded our knowledge of the diversity and evolution of viruses associated with all domains of life. However, as most of these ‘virome’ studies are primarily descriptive, our understanding of the predictors of virus prevalence and diversity, and their variation in space and time, remains limited. For example, we do not yet understand the relative importance of ecological predictors (e.g., seasonality, habitat) versus evolutionary predictors (e.g., host and virus phylogenies) in driving virus prevalence and diversity. Few studies are set up to determine what factors predict the composition of the virome of individual hosts, populations, or species. In addition, most studies of virus ecology represent a snapshot of single viromes at a single point in time and space. Fortunately, recent studies have begun to use metagenomic data to directly test hypotheses about the evolutionary and ecological factors which drive virus prevalence, sharing and diversity. By synthesising evidence across studies, we present some over-arching ecological and evolutionary patterns in virome composition, and illustrate the need for further work to quantify the drivers of virus prevalence and diversity.

The need for fuel oil for the transportation sector increases every year, while non-renewable energy reserves are increasingly depleting. Subsidized fuel oil is seen as not on target, the heavy burden of fuel oil subsidies limits fiscal space so that APBN allocations for other development sectors are limited. The increase in fuel prices is one of the considerations in choosing fuel. This research aims to analyze the factors that influence fuel oil preferences in North Purwokerto. The sample in this study amounted to 96 respondents who were calculated using the Lemeshow formula. This research uses logistic regression analysis. The results of the logistic regression analysis show that vehicle age, engine capacity, income, gender, and volume of fuel use have a significant effect on preferences for subsidized and non-subsidized fuel oil in North Purwokerto. Meanwhile, type of vehicle, number of family dependents, type of work, regional origin and social status do not have a significant effect on preferences for subsidized and non-subsidized fuel oil in North Purwokerto. The implication of this research is the need to increase consumer knowledge about the use of fuel oil that is adjusted to vehicle conditions. The government can make policies so that subsidized fuel can be received by people who are entitled to need it.

The rainfall data is usually obtained from meteorological stations, which many sill observed manually in Indonesia and can lead to an observation error. Remote sensing rainfall data observed by satellite offer interesting alternatives to overcome the limitation of existing meteorological stations in Indonesia. It offers accuracy, spatial coverage, timeliness and cost effectiveness. However it contains bias if compared to land based station. This research will evaluate rainfall data observed in PERSIANN (Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks) in Brantas Hulu Watershed. The rainfall data of 13 years from 12 stations is evaluated to obtain area averaged rainfall using Thiessen Polygon method. Three datasets from PERSIANN, PERSIANN CCS and PERSIANN CDR are compared statistically with the area averaged area for daily, monthly and yearly rainfall. Bias correction is performed using Quantile Mapping to match the cumulative distribution curve from the area averaged rainfall. Verification of bias correction is performed using 2 years data from 2019 to 2020. Finally, the extreme rainfall analysis is performed to test the corrected data for design rainfall calculations. The correlation of daily data shows poor agreement for all three datasets with correlation coefficient below 0,40. The monthly and yearly data gives better correlation with coefficient above 0,80. It shows that for time series event, the satellite data gives poor correlation with the area averaged rainfall. However, quantile mapping correction gives consistent cumulative distribution agreement for correction and model verification. The verification analysis shows an increase in coefficient correlation from 0.387 to 0.43 (daily) and 0.887 to 0.915 (monthly). In addition, there is a decrease in normalized root mean square error (NRMSE) from 31.03% to 16.91% (daily) and 46.03% to 14.03% (monthly). A decrease in normalized mean absolute error (NMAE) occurred from 16.12% to 9.74% (daily) and 31.67% to 10.07% (monthly). Beside that, the results of extreme rainfall analysis produce values that are very close to the rain station. So it is found that the PERSIANN CCS quantile mapping regression model is the best in improving data quality.

The Airside is a vital area related to aircraft movement. A drainage system needs to be implemented at each airport to support airside safety. This research aims to find out the drainage system at several airports. The exploration study of the drainage system on the air side uses a qualitative method based on a systematic literature review by comparing studies obtained through Google Scholar in the 2015-2024 period. Then, the author analyzes the issues raised using GAP analysis techniques. The sample airports are Juwata Tarakan Airport, Rahadi Oesman Ketapang Airport, Sultan Muhammad Salahuddin Bima Airport, Kualanamu Deli Serdang Airport, and Husein Sastranegara Bandung Airport. This study found that several factors, including structural damage, inefficiency of channel dimensions, instability of retaining walls, lack of rain catchment areas, and accumulated sedimentation, cause the overflow of water that arises when rain occurs. Therefore, it can be concluded that the airport needs to evaluate the effectiveness of channel dimensions using hydrological and hydraulic analysis methods. In addition to evaluation, the drainage system needs to be maintained, which refers to KP 94 of 2015 and KP 326 of 2019. Drainage maintenance activities can be carried out by cleaning sedimentation, vines, grass, and sediment in the channel to save operational costs and increase the channel's life. In addition, overflows on the air side can be minimized, and the safety of flight operations can be guaranteed.
