Authors: Gines-Palestino Ruby , Montalvo-Romero Carlos , Luna-Solano Guadalupe , Amador-Gómez Luis , Cantú-Lozano Denis
Published: June 2023

Due to its multiple applications, zinc oxide (ZnO) is one of the most used materials in science and technology. Therefore, this research carried out the synthesis of ZnO and Pt-ZnO nanoparticles (NPs) by the direct precipitation method, which is characterized by being simple and reproducible, using two different precipitating agents, potassium hydroxide (KOH) and sodium hydroxide (NaOH); for the doping of Pt-ZnO NPs was used platinum acetylacetone. To evaluate the effect of the precipitating agent on the properties of each doped material, they were characterized by Fourier transform infrared spectroscopy, where the Zn-O vibrations were more pronounced using KOH. X-ray diffraction analysis shows a hexagonal structure (wurtzite) formation for ZnO with NaOH, obtaining a smaller crystal size than the other synthesized materials. Scanning electron microscopy analysis showed hexagonal and hemispherical shapes for ZnO (with NaOH and KOH) and Pt-ZnO (with NaOH), respectively; also, cylindrical shapes were obtained for Pt-ZnO (with KOH). The highest band gap obtained was for the Pt-ZnO material synthesized with KOH.

Authors: Hsiao tung-Yu , Sfarra stefano , Liu yi , Yao yuan
Published: June 2023

In this work, the Hilbert-Huang transform (HHT) is utilized to improve the non-destructive testing based on thermographic data and enhance the defect detection of materials. In previous studies, HHT has been proven to be powerful for signal processing and analysis in 1D time series. Its generalization to 2D and 3D Euclidean space has also demonstrated the widespread utilizations of HHT. The authors performed experiments on a mosaic sample with defects deliberately introduced. By using the proposed method, we successfully extracted informative defect signals out of noisy raw thermographic data and provided accurate yet more intuitive testing results

Published: June 2023

In this work, we have addressed the problem of thermal camera drift. The change of the temperature of the thermal camera influences the measured accuracy, up to 2 °C of error compared to the real temperature of the target. it is then essential to control the temperature of the camera. In this way, we built a cold box sized to Flir A325sc camera. The cold box is detailed. By varying the ambient temperature and camera one, we test the quality of temperature drift compensation by comparing the apparent temperature to a fixed reference temperature (50°C). We show that non-contact temperature accuracy can be improved by fixing the camera temperature for a given ambient temperature in range [10°C, 40°C].

Published: June 2023

Optical infrared thermography (IRT) has shown significant potential and advantages in defect detection in fiber reinforced polymers(FRPs) due to its capabilities of realizing non-contact and quasi real-time measurements over a large detection area. Simulation of optical IRT is of great importance as it provides support for model-based development, implementation and optimization of the experiment. To this end, the authors have developed and implemented a versatile and fast 3D simulator, based on finite element (FE) approach, for multi-layer anisotropic materials. In order to model defects, an interface element formulation has been developed which has several advantages over the standard volume element approach. The developed simulator has been benchmarked for different cases with commercial FE software. It is found that our simulator provides identical results, but more importantly, it is shown that the use of interface elements (instead of the standard volume elements) is computationally much more efficient. To better represent experiments, realistic non-uniform optical heating conditions are also implemented in the simulator. Besides, a stochastic defect modelling technique, on the basis of a morphological approach, is proposed to generate arbitrary, yet realistic, defect geometries. Finally, the fast simulator is programmed in a fully parametrized manner, which makes it suitable for generating large and diverse virtual databases which could be employed for deep learning purposes in thermography. A fully functional GUI module will be made available to the community.
IRT-GAN: A GAN framework for automated defect segmentation in composites using infrared thermography
Authors: Liangliang cheng , Tong zongfei , Xie shejuan , Kersemans mathias
Published: June 2023

Infrared thermography (IRT) for non-destructive testing of fiber reinforced polymers is becoming increasingly popular in industrial applications. However, conventional post-processing techniques often require intervention by experienced operators to confirm and evaluate defects. To further enhance the detectability of defects and alleviate operator-intervention, this study proposes a deep learning generative adversarial network (GAN) framework, termed IRT-GAN. IRT-GAN takes six pre-processed thermal images as input and progressively fuses them through a multi-headed fusion strategy. As such, the developed IRT-GAN method yields a single segmented defect map in an automated manner. It is worth mentioning that the presented IRT-GAN model has been exclusively trained on virtual data, and it is applied on experimental datasets of fiber reinforced polymers having different defect types, sizes, and depths. A high prediction accuracy is demonstrated, showing the good generalization capacity of the developed IRT-GAN.

Published: June 2023

Introduction:

To understand the risk factors of asthma, we combined genome-wide association
study (GWAS) risk loci and clinical data in predicting asthma using machine-learning
approaches.

Methods:

A case-control study with 123 asthmatics and 100 controls was conducted in the Zhuang
population in Guangxi. GWAS risk loci were detected using polymerase chain reaction, and clinical
data were collected. Machine-learning approaches were used to identify the major factors that
contribute to asthma.

Results:

A total of 14 GWAS risk loci with clinical data were analyzed on the basis of 10 times the
10-fold cross-validation for all machine-learning models. Using GWAS risk loci or clinical data,
the best performances exhibited area under the curve (AUC) values of 64.3% and 71.4%, respectively.
Combining GWAS risk loci and clinical data, the XGBoost established the best model with
an AUC of 79.7%, indicating that the combination of genetics and clinical data can enable improved
performance. We then sorted the importance of features and found the top six risk factors
for predicting asthma to be rs3117098, rs7775228, family history, rs2305480, rs4833095, and body
mass index.

Conclusion:

Asthma-prediction models based on GWAS risk loci and clinical data can accurately
predict asthma, and thus provide insights into the disease pathogenesis.

Published: June 2023

Resveratrol (Res), a polyphenol found in red wine, has been shown to
decelerate aging, the progressive loss of physiological integrity and cellular senescence,
characterized by the inability to progress through the cell cycle. No successful clinical
trials have yet to be completed in humans on dose limitations. Yet, the potent anti-aging
and anti-senescence efficacy of Res has been documented in several in vivo animal
models. In this review, we highlight the molecular mechanisms of Res efficacy in antiaging
disorders, such as diabetes, neurodegenerative disorders, eye diseases, and
cardiovascular diseases.

in Mild Cognitive Impairment and Alzheimer’s Disease
Authors: Xiong Yu , Ye Chenghui , Sun Ruxin , Chen Ying , Zhong Xiaochun , Zhang Jiaqi , Zhong Zhanhua , Chen Hongda , Huang Min
Published: June 2023

Background:

Alterations in functional connectivity have been demonstrated in Alzheimer’s
disease (AD), an age-progressive neurodegenerative disorder that affects cognitive function;
however, directional information flow has never been analyzed.

Objective:

This study aimed to determine changes in resting-state directional functional connectivity
measured using a novel approach, granger causality density (GCD), in patients with AD, and mild
cognitive impairment (MCI) and explore novel neuroimaging biomarkers for cognitive decline detection.

Methods:

In this study, structural MRI, resting-state functional magnetic resonance imaging, and neuropsychological
data of 48 Alzheimer’s Disease Neuroimaging Initiative participants were analyzed,
comprising 16 patients with AD, 16 with MCI, and 16 normal controls. Volume-based morphometry
(VBM) and GCD were used to calculate the voxel-based gray matter (GM) volumes and directed
functional connectivity of the brain. We made full use of voxel-based between-group comparisons of
VBM and GCD values to identify specific regions with significant alterations. In addition, Pearson’s
correlation analysis was conducted between directed functional connectivity and several clinical variables.
Furthermore, receiver operating characteristic (ROC) analysis related to classification was performed
in combination with VBM and GCD.

Results:

In patients with cognitive decline, abnormal VBM and GCD (involving inflow and outflow
of GCD) were noted in default mode network (DMN)-related areas and the cerebellum. GCD in the
DMN midline core system, hippocampus, and cerebellum was closely correlated with the Mini-
Mental State Examination and Functional Activities Questionnaire scores. In the ROC analysis combining
VBM with GCD, the neuroimaging biomarker in the cerebellum was optimal for the early detection
of MCI, whereas the precuneus was the best in predicting cognitive decline progression and
AD diagnosis.

Conclusion:

Changes in GM volume and directed functional connectivity may reflect the mechanism
of cognitive decline. This discovery could improve our understanding of the pathology of AD and
MCI and provide available neuroimaging markers for the early detection, progression, and diagnosis
of AD and MCI.

Published: June 2023

Background:

Ferroptosis is a new type of programmed apoptosis and plays an important
role in tumour inhibition and immunotherapy.

Objective:

In this study, we aimed to explore the potential role of ferroptosis-related genes (FRGs)
and the potential therapeutic targets in oral cavity squamous cell carcinoma (OCSCC).

Methods:

The transcription data of OCSCC samples were obtained from the Cancer Genome Atlas
(TCGA) database as a training dataset. The prognostic FRGs were extracted by univariate Cox
regression analysis. Then, we constructed a prognostic model using the least absolute shrinkage
and selection operator (LASSO) and Cox analysis to determine the independent prognosis FRGs.
Based on this model, risk scores were calculated for the OCSCC samples. The model’s capability
was further evaluated by the receiver operating characteristic curve (ROC). Then, we used the
GSE41613 dataset as an external validation cohort to confirm the model’s predictive capability.
Next, the immune infiltration and somatic mutation analysis were applied. Lastly, single-cell transcriptomic
analysis was used to identify the key cells.

Results:

A total of 12 prognostic FRGs were identified. Eventually, 6 FRGs were screened as independent
predictors and a prognostic model was constructed in the training dataset, which significantly
stratified OCSCC samples into high-risk and low-risk groups based on overall survival.
The external validation of the model using the GSE41613 dataset demonstrated a satisfactory predictive
capability for the prognosis of OCSCC. Further analysis revealed that patients in the highrisk
group had distinct immune infiltration and somatic mutation patterns from low-risk patients.
Mast cell infiltrations were identified as prognostic immune cells and played a role in OCSCC
partly through ferroptosis.

Conclusion:

We successfully constructed a novel 6 FRGs model and identified a prognostic immune
cell, which can serve to predict clinical prognoses for OCSCC. Ferroptosis may be a new
direction for immunotherapy of OCSCC.

Authors: Tan Si Ying , Tang Matilda Swee Sun , Ong Chin-Ann Johnny , Tan Veronique Kiak Mien , Shannon Nicholas Brian
Published: June 2023

BACKGROUND

The COVID-19 pandemic has led to a decrease in cancer screening due to the redeployment of health care resources and public avoidance of health care facilities. Breast cancer is the most common cancer diagnosed in female individuals, with improved survival rates from early detection. An avoidance of screening, resulting in late detection, greatly affects survival and increases health care resource burden and costs.

OBJECTIVE

This study aimed to evaluate if a sustained decrease in public interest in screening occurred and to evaluate other search terms, and hence interest, associated with that.

METHODS

This study used Google Trends to analyze public interest in breast cancer screening and symptoms. We queried search data for 4 keyword terms (“mammogram,” “breast pain,” “breast lump,” and “nipple discharge”) from January 1, 2019, to January 1, 2022. The relative search frequency metric was used to assess interest in these terms, and related queries were retrieved for each keyword to evaluate trends in search patterns.

RESULTS

Despite an initial drastic drop in interest in mammography from March to April 2020, this quickly recovered by July 2020. After this period, alongside the recovery of interest in screening, there was a rapid increase in interest for arranging for mammography. Relative search frequencies of perceived breast cancer–related symptoms such as breast lump, nipple discharge, and breast pain remained stable. There was increase public interest in natural and alternative therapy of breast lumps despite the recovery of interest in mammography and breast biopsy. There was a significant correlation between search activity and Breast Cancer Awareness Month in October.

CONCLUSIONS

Online search interest in breast cancer screening experienced a sharp decline at the beginning of the COVID-19 pandemic, with a subsequent return to baseline interest in arranging for mammography followed this short period of decreased interest.

Comparing Walking-Related Everyday Life Tasks of Children with Gait Disorders in a Virtual Reality Setup With a Physical Setup: Cross-Sectional Noninferiority Study (Preprint)
Authors: Rhiel Sophia , Kläy Andrina , Keller Urs , van Hedel Hubertus J A , Ammann-Reiffer Corinne
Published: June 2023

BACKGROUND

A frequent rehabilitation goal for children with gait disorders is to practice daily-life walking activities. Unfortunately, these are often difficult to practice in a conventional therapeutic setting. Virtual reality (VR) with head-mounted displays (HMDs) could be a promising approach in neurorehabilitation to train such activities in a safe environment. First, however, we must know whether obstacles in VR are indeed mastered as obstacles.

OBJECTIVE

This study aimed to provide information on whether VR is feasible and motivating to induce and practice movements needed to master real obstacles in children and adolescents with gait disorders. Furthermore, this project aims to evaluate which kinds of everyday walking activities are appropriate to be practiced in VR.

METHODS

In this cross-sectional study, participants stepped over a bar, crossed a gap, balanced over a beam, and circumvented stationary obstructions arranged in a course under real physical and virtual conditions wearing a VR HMD. We recorded the respective primary outcomes (step height, step length, step width, and minimal shoulder-obstacle distance) with motion capture. We then calculated the mean differences and 95% CI of the spatiotemporal parameters between the VR and physical setup and later compared them using noninferiority analysis with margins defined a priori by a clinical expert panel. Additionally, the participants responded to a standardized questionnaire while the therapists observed and evaluated their movement performance.

RESULTS

We recruited 20 participants (mean age 12.0, range 6.6-17.8 years) with various diagnoses affecting their walking ability. At 3.77 (95% CI 1.28 to 6.26) cm, the mean difference in step height of the leading foot in the overstepping task did not exceed the predefined margin of –2 cm, thus signifying noninferiority of the VR condition compared to mastering the physical obstacles. The same was true for step length (–1.75, 95% CI –4.91 to 1.41 cm; margin –10 cm), step width (1.05, 95% CI 0.20 to –1.90 cm; margin 3 cm), and the minimal shoulder-obstacle distance (0.25, 95% CI –0.85 to 0.35 cm; margin –2 cm) in the other tasks. Only the trailing foot in the overstepping task yielded inconclusive results.

CONCLUSIONS

Children with gait disorders perform everyday walking tasks like overstepping, crossing, balancing, or circumventing similarly in physical and VR environments, suggesting that VR could be a feasible therapeutic tool to practice everyday walking tasks.

Authors: Dewayani Evita Ratih
Published: June 2023

Background: High-risk pregnancy is a severe threat to the health and life of pregnant women and babies, considering that this can increase the risk of complications during pregnancy, childbirth and puerperium. About 20 million women worldwide have high-risk pregnancies, and it is known that more than 800 die each day. Pregnant women have potential risks during pregnancy, childbirth and the puerperium. The mother's lack of knowledge about pregnancy health problems and health service providers can increase inappropriate handling risk by health workers. So, women should understand the concept of high-risk pregnancies to reduce these risks. Research Objectives: To determine the childbirth experiences in mothers at high risk in the delivery process at UGM Academic Hospital. Method: Qualitative Research with Descriptive-Narrative Design. Results: The mothers knew the risks of pregnancy, but they were less aware of the risks of other pregnancies. Mothers’ experience in choosing a place of delivery was influenced by personal experiences, family, friends, or other people. The availability of adequate hospital facilities, service flow, and ownership of insurance coverage were also other factors in choosing a maternity hospital. Conclusion: Mothers are aware of the risks of pregnancy, but they are less aware of other pregnancy risks. Suggestion: Mothers should be aware of the risks of pregnancy and need to learn more about other pregnancy risks. It is hoped that they will be better prepared if a high-risk pregnancy occurs.

The SARS-CoV 2 virus pandemic has been a scourge since 2020. The number of cases that continues to increase, both mild, moderate, severe-critical confirmed cases are directly proportional to the need for treatment rooms, both ordinary wards and intensive care units (ICU), which is inversely proportional to the available capacity. room. Based on research, the high mortality and morbidity rate due to COVID 19 is due to the incidence of patient sepsis. Research abroad states that the value of D-dimer is a prognostic factor for COVID-19 patients, although there is no agreement on the best cut-off point for specificity and sensitivity. hypercoagulability conditions and increased lactic acid in patients with severe sepsis. It is necessary to evaluate the role of this laboratory result in estimating the prognosis of COVID-19 patients in Indonesia. There is no study that examines the relationship between the incidence of sepsis and the characteristics of hypercoagulability with the dominance of the thrombotic process in COVID19 patients in Indonesia. The purpose of this study was to provide information to health workers about the role of D-dimer value as a prognostic factor for severe-critical COVID-19 patients. This quantitative retrospective research data in the form of proportions were collected for 12 months from the medical records of the UGM Academic Hospital of patients with confirmed severe-critical COVID-19. Overall survival was assessed by the Kaplan-Meier curve. The cut-off determination for the D-dimer variable was carried out using the Receiver Operating Curve (ROC) followed by the calculation of the Youden index. Then the hazard ratio was determined by cox regression with a p value of <0.05 which was considered significant. Statistical analysis with SPSS version 26 software.
THE DISTINCTION BETWEEN BRICS AND G7 IN RESPONDING TO THE UKRAINE-RUSSIA CRISIS: G20 MULTILATERAL CRISIS?
Authors: Cahayani Ica , Fachrurreza Ahmad Mujaddid , Puspita Agata Nina
Published: June 2023

Introduction/Main Objective: This research discusses the differences in BRICS and G7 responses to the Ukraine-Russia conflict, where these two groups consist of countries with different political interests. Following the results of the G7 and BRICS Summits, both responded differently to the Ukraine-Russia crisis. Background Problem: Differences in response are proposed because the G20 has the vision to achieve the resolution of policy issues on problems that hinder world economic growth, one of which is the food crisis caused by the Uraina-Russia conflict. The selection of the G7 and BRICS's different responses is the right strategy to determine how much potential the G20 has. It is difficult to achieve its goal of providing solutions for the world economy thanks to the structure of its members, who have diverse interests and responses to the Ukraine-Russia crisis. Novelty: This study uses interest-based theory to analyze the differences in the responses of the G7 and BRICS. This theory seeks to explain the formation of the G20's international regime by dismantling aspects of the fundamental interests behind the cognitive states that decided to establish the international regime of the G20. Method: The method used in this research is the discourse analysis method in a case set because this study wants to see changes in discourse related to the multilateral G20. Findings/Results: The complexity of trading, namely the BRICS and G7, with different responses and interests in responding to the Ukrainian crisis, can encourage a multilateralism crisis in the G20. The research results prove that the complexity of reporting generates different interests, so the response to the Ukrainian-Russian crisis tends to differ. Conclusion: The G20 has not been able to overcome the different interests of its members in solving the problem of the world food crisis because the discussion of the world food crisis is linked to the discussion of Ukrainian-Russian security politics.

Keterbatasan sumber daya yang dimiliki perangkat IoT menjadikannya target ideal untuk diluncurkan serangan Denial of Service (DoS), termasuk SYN flood. Serangan ini cenderung menargetkan sumber daya IoT yang krusial, termasuk CPU. Apabila dilakukan secara terus menerus, serangan ini mampu menguras sumber daya IoT dan membuatnya kehilangan fungsionalitasnya. Penerapan iptables pada Raspberry Pi mampu meminimalkan dampak serangan SYN flood. Iptables memiliki berbagai chains dan tables dengan kemampuan dan fungsi yang berbeda. Penelitian ini bertujuan untuk menganalisis perbedaan pengaruh penggunaan iptables chains terhadap penggunaan CPU Raspberry Pi. Penggunaan CPU yang semakin rendah memperkecil kemungkinan terjadinya DoS. Hasil penelitian ini kemudian akan dibandingkan dengan penggunaan CPU ketika aturan iptables pada penelitian terdahulu diterapkan. Hasilnya, kedua aturan mengonsumsi CPU dalam persentase yang hampir sama.
CHANGING THE LEGAL STATUS OF ANIMALS: LEGISLATION AND LITIGATION
Authors: Todorović Zorana
Published: June 2023

This paper addresses the issue of the legal status of non-human animals and the possibility of changing it from the status of things or property, to the status of non-things, or better, sentient beings. Key arguments for the change of their status are discussed, including the argument from marginal cases, and the scientific evidence indicating that many animals are sentient beings. Two ways of initiating such changes seem most promising: legislation, i.e. the modification of civil codes, and litigation, i.e. filing lawsuits on behalf of individual animals. It is argued that legislative changes are necessary for moving animals out of the legal category of things and into the category of sentient beings that can bear rights. On the other hand, litigation could bring about a more radical change of the legal status of some animals.
THE CHARACTERISTICS OF TITLE BLOCKS ON NEWS PORTALS: THE CASE OF THE CRIME COLUMN
Authors: Jevtović Ana , Marić Katarina
Published: June 2023

A large number of news portals and social networks in the everyday communication environment has significantly influenced the change of the traditional genre structure, but also the technique of collecting, selecting, processing and distributing information. Under the pressure of productivity and clickbaiting, crime cases columns in market-centric media are becoming an increasingly important part of daily reporting. Hence, the title blocks on the portals are the subject of this paper, with the hypothesis that their visual and textual contents differ significantly from those in traditional newspapers. The informative core of the message, characterized by sensationalism and intent to awaken curiosity, and visually enriched with photographs of actors and capital letters, greatly influences the audience’s choice. This paper, through the case study of the disappearance of a 27-year-old young man from a neighboring country, determines the basic characteristics of news headlines and reports published on the news portal “Serbia Today” (Serb. „Srbija Danas”). The results of quantitative and qualitative content analysis are also relevant for other portals, because a large number of texts are shared between the different portals. Emotionally and expressively marked words aimed at the attention of users awaken the users’ empathy and desire to actively participate in a social chronicle that excites and upsets the wider community. Qualitative analysis also indicated a close connection between the headline and the content of the report, with a predominantly sensationalist tone, as well as a clear commitment to constant public attention.

Published: June 2023

Tourism is more dependent on the environment than any other economic activity. Modern tourism requires the use of vast areas of the environment, untouched or well-protected, because only in such areas can it hope to develop so as to be of economic and social benefit. Having in mind the great impact of tourism on the environment, its development needs to harmonise with the concept of sustainability. Ecotourism is one of the selective forms of tourism based on natural resources and their use over time, and it is characterised by tourist offers with unique values. Accordingly, the research subject of this paper is ecotourism, which aims to enable the tourism industry to operate while preserving the environment. The aim of this paper is to analyse the achieved level of environmental quality as the basis for the development of ecotourism, and as a component of the competitiveness of the Republic of Serbia’s tourism.
THE CONTRIBUTION OF DEVELOPMENT FACTORS TO ECONOMIC GROWTH ON VARIOUS GDP LEVELS – THE MIDDLE-INCOME TRAP
Authors: Todorović Miloš , Kalinović Milan
Published: June 2023

This paper analyses the intensity of the influence of foreign direct investments, exports of goods and services, and research and development expenditure on GDP growth of developed and developing countries. Panel regression analysis determined that the exports of goods and services make the largest contribution to growth on middle levels of income. In fact, the contribution the export of goods and services makes to growth on middle levels of income is two times larger than in countries with a high GDP. The most essential impact on countries with a high GDP level was made by research and development expenditure, which is 3.5 times larger than its impact on the developing Balkan countries. The phenomenon of the Middle-Income Trap can be explained by insufficient research and development expenditure. Foreign direct investments are not statistically significant for the GDP growth of observed countries, but they achieve far better results on low development levels. The empirical data, presented in figures, confirms the conclusions of the econometric analysis.
THE ROLE AND IMPORTANCE OF EMPLOYEE PERFORMANCE ASSESSMENT FOR THE SUCCESS OF HOTELS IN BELGRADE
Authors: Vasić Živorad , Petrović Pero
Published: June 2023

In specific business conditions and crisis situations, the commitment to service quality and employee performance, i.e. the interdependence of these components, is extremely important. The quality of a service largely depends on the efficiency and effectiveness of workers, and on their permanent learning and improvement, which raise the employees’ motivation to deliver a high-quality service. That is why efforts to promote the quality of services must be based on managing the behaviour and education of employees, which, from the aspect of synergy, leads to the so-called ‘learning organisation’. Therefore, the permanent learning organisation is a concept that is becoming an increasingly widespread philosophy in companies oriented towards proactive behaviour. In order to see to what extent this philosophy-orientation is present in hotels in Belgrade, we conducted primary research in the following hotels: Majestic, Zira, Heritage, Holiday INN, and the Crown Plaza of the IHG hotel chain.
