The properties of the ion flow have been experimentally determined depending on the parameters of a gridless two-electrode ion shutter and the conditions of ion transport in the drift tube. The transverse structure of the ion flow in the plane of the collector is investigated using a collector consisting of concentric rings. The resulting ion current distributions have a radial structure that varies depending on experimental conditions. Theoretical estimates are given to take into account the degree of influence of the space charge on the transverse dimensions of the ion beam in the drift field. The agreement of experimental and theoretical results allows one to conclude that the observed phenomena are caused by a space charge.

The environmental crisis is an outstanding topic nowadays. Given that it is basically causedby human activity, this issue is worth examining at all levels of society. The present studyinvestigated the individuals’ visual attentional patterns and the possible attentional biases related to pictures displaying environmental problems, in comparison to undisturbed natureand social scenes as control stimuli, within the framework of a reaction-time task. Changesin participants’ mood and their self-reported environmental awareness were also measured.However, only the negative social scenes resulted attentional bias, the environmental topicswere not able to do that. Albeit the mood of the participants deteriorated during the experiment,it did not have any correlation with any other variables, and either did the environmentalawareness. We displayed the stimuli during the task only for a short period of time, thereby wetargeted to reach automatic attentional responses. Our results reflect to the fact, that the topicof the environmental crisis is not suitable to do this. This phenomenon propounds the demand ofexplanations behind this phenomenon (like the possible evolutionary background).

Published: August 2022

The fuzzy logic Mamdani model is a fuzzy reasoning system that can be used to calculate values based on various criteria for evaluating teacher performance. In this study, three fuzzy sets were used to determine the level of success of teachers in teaching through online media in one of the vocational schools in North Sumatra: the teacher set, the value set, and the success rate set. The teacher set is divided into three criteria: bad, sufficient, and good teachers. The set of values is also divided into three categories: bad, sufficient, and good. Furthermore, the set of success rates is divided into three categories: low, medium, and high success rates. The goal of this study is to use the mamdani fuzzy logic method to assess the level of success in teaching teachers using online media. According to the study's findings, the mamdani method could be used in this situation.

Published: August 2022

The study of consumer choice is an important classical research task for various markets for goods and services. This fully applies to new products and devices for household, personal monitoring, and self-monitoring of health status. In the last decade, a few such products have appeared and have become available to a wide range of buyers, in particular, fitness trackers and smartwatches of various manufacturers, brands, and models. It has become quite difficult for the buyer and the user to compare and choose a specific one. Therefore, the purpose of the work was to study the market of fitness trackers and smartwatches, determine the main criteria for their comparison by the consumer, and apply multi-criteria approaches for their assessment and selection, both by buyers and by sellers themselves, their sales specialists. The research methods used were consumer surveys, market systems analysis, multicriteria computer modeling. The proposed and described approach makes it possible to obtain computationally substantiated, objective numerical estimates for special fitness monitoring device, selected for compare consideration. Thus, it is possible to provide information support for consumer choice, as well as to carry out a comparative analysis of the range of products offered by their sellers themselves.

Authors: Shahbazi Parisa , Yasrebi Behzad , Afshar Cyrus , Haghipour Siamak , Abedi-Firouzjah Razzagh
Published: August 2022

Purpose: At Magnetic Resonance Imaging (MRI), artifacts arising from metal implants are an obstacle to obtaining optimal images. This study aimed to evaluate the impact of View-Angle Tilting (VAT) and Slice Encoding for Metal Artifact Correction (SEMAC) techniques for the artifact reduction of patients during knee MRI with metal implants.
Materials and Methods: The MR images without any intervention of the knee from 20 patients with knee prostheses were used. The VAT and SEMAC metal artifact reduction techniques were applied to all the MR images. Volume and mass of the metal prosthesis were quantified using the MATLAB program and compared with the real measurements using nonparametric Wilcoxon tests in SPSS software. The qualitative analysis was performed by two blinded observers regarding the score of artifact size, distortions, image quality, and visualization of bone marrow and soft tissues adjacent to metal implants. In addition, Cohen’s kappa values were used for inter-observer agreement.
Results: The average volume of the platinum based on the conventional, VAT, and SEMAC methods was estimated at 14.22 ± 0.43, 14.05 ± 0.4, and 13.3 ± 0.45 cm3, respectively. The statistical analysis showed no significant difference (P > 0.05) between the mean value of the platinum volume for the SEMAC method and the real measurement (13.6 ± 0.33 cm3). Furthermore, regarding the conventional, VAT, and SEMAC sequences, the mean mass of the platinum was obtained at 305.02 ± 9.22, 301.37 ± 8.58, and 285.28 ± 9.65 g, respectively, with the P-Value of 0.005, 0.009, and 0.268, compared to the real measurements (286.81±8.75 g). Notably, the blinded readers demonstrated that the SEMAC method was remarkably superior quality compared with VAT and conventional acquisitions (P-Value< 0.05).
Conclusion: The knee prosthesis metal artifact was reduced using the VAT and SEMAC techniques, in a way that, the reduction was significant by the SEMAC method. In addition, concerning the qualitative observer analysis, the application of the SEMAC technique provides improved visualization of tissue structures adjacent to metal implants.

Purpose: A powerful imaging method for evaluating brain patches is resting-state functional Magnetic Resonance (rs-fMRI) Imaging, in which the subject is at rest. Artificial Neural Networks (ANN) are one of the several Alzheimer's Disease (AD) analysis and diagnosis methods used in this study. We investigate ANNs' ability to diagnose AD using rs-fMRI data.
Materials and Methods: The acquisition of functional and structural magnetic resonance imaging was applied for 15 AD, 17 mild cognitive impairment, and ten normal healthy participants. Time series of blood oxygen level-dependent were extracted from the multi-subject dictionary learning brain atlas after pre-processing. This study develops a one-dimensional Convolutional Neural Network (CNN) using extracted signals of the functional atlas for differential diagnosis of AD.
Results: Applying the proposed method to rs-fMRI signals for classifying three classes of Alzheimer’s patients resulted in overall accuracy, F1-score, and precision of 0.685, 0.663, and 0.681, respectively. Using 39 regions in the brain and proposing a quite simple network than most of the available deep learning-based methods are the main advantages of this model.
Conclusion: rs-fMRI signal recognition based on a functional atlas with the application of a deep neural network has a pattern recognition capability that can make a differential diagnosis with an acceptable level of accuracy and precision. Therefore, deep neural networks can be considered as a tool for the early diagnosis of AD.

Purpose: With the widespread application of ionizing radiation in medical practice, concerns have been increased regarding the hazardous effects of radiation. Studies have demonstrated that some variables such as body dimensions affect the absorbed radiation dose. In this study, the association between Body Mass Index (BMI) and absorbed dose in Computed Tomography (CT) is investigated.
Materials and Methods: A total of 550 adult patients (age ≥ 15 years) were included in the study. The height and weight of the patients were recorded for BMI calculation. Dosimetry data were acquired from digital imaging and communications in medicine dose reports. The patients were categorized into five groups according to their BMI, the categorized information was then imported into ImPACT Dose software for calculation of Size-Specific Dose Estimate (SSDE) and organ and effective doses. The relationship between patient BMI and the effective dose was also determined.
Results: A higher BMI contributed to increased radiation dose and SSDE in patients who had undergone chest or abdomen-pelvis CT examination (p < 0.05).  
Conclusion: The radiation dose is related to a patient’s BMI and rises with an increase in BMI. Accordingly, it is suggested that BMI and other variables, such as the type of scan and other body dimensions, which affect the radiation dose, can be used to estimate the radiation dose before performing CT. This estimation can be considered for the justification and optimization of CT examinations.

Published: August 2022

Introduction: Unplanned pregnancy is a public health problem that affects maternal and child health, including maternal death, abortion, and low birth weight. Consequently, the government established family planning for action to prevent and reduce the health problems for most disadvantaged women. Objective: This study was conducted to examine the overall prevalence of unplanned pregnancy and its associated risk factors in Ethiopia.
Methods: A Population based cross-sectional study was conducted from Ethiopian 2016 demographic health survey data. A total of 3894 pregnant women were included in the study and the samples were selected trough multistage stratified cluster sampling. Uni-variate and multiple logistic regression analysis were used to identify factors associated with an unplanned pregnancy. Variables with p-value < 0.05 were identified as significant factors.
Results: Among 3894 understudy pregnant women, 31.02% (95% CI = 28.21-38.58 %) of pregnancies was unplanned. The analysis result revealed that women whose age ≤ 30 years [adjusted odds ratio(AOR) = 5.42, 95 % CI=2.38 - 12.34], women in rural [AOR =1.11, 95% CI=1.03 - 2.39], illiterate women [AOR =2.3,95% CI=2.02 - 4.09], women drinks alcohol [AOR =1.45,95% CI=1.31- 1.67], smoker women [AOR = 1.52, 95% CI 1.49 - 2.65 ],women chewing chat[AOR =1.66, 95% CI=1.66 1.18 - 2.33], unemployed women[AOR =4.97, 95%CI=1.31-12.38], poor economic level [AOR =8.42,95%CI=5.87- 14.39] and noneuser contraceptive methods [AOR =1.7, 95% CI=1.14 – 3.87] were found to be associated with unplanned pregnancy.
Conclusion: The prevalence of unplanned pregnancy in the study area was 31.02%. The findings suggest that certain groups of women are at increased risk of unplanned pregnancy and would benefit from targeted family planning interventions.

Published: August 2022

Introduction: Iran is facing to a rapid change in the epidemiological pattern of HIV. The trend of annual number of new HIV infections and factors associated with the development of HIV over the last two decades in Iran, were examined.
Methods: The data were retrospectively collected from patients who attended the Behavior Diseases Consultation Center of Mashhad University of Medical Sciences in Iran. Individuals were contributed if they were HIV-positive. Baseline factors including demographic, behavioral and clinical characteristics for all participants were examined. Changes in population characteristics were assessed using chi-square test or the Fisher’s exact test.
Results: From 1989 to 2014, 584 individuals were eligible for present analysis according to the inclusion criteria. Most patients were men (87%) with most being 36–52 years old, unemployed (58%), married (39.3%), less educated (47.7%) and had a history of imprisonment (83%). The most common modes of HIV transmission were injection drug use (IDU) (51.4%) and IDU along with the sexual relationship (26.5%). These transmission modes varied significantly according to gender (p-value<0.001). Similarly, IDU and sexual relationship were most important transmission modes in males and females, respectively. The number of new HIV infections through sexual-related modes has risen sharply in recent years.
Conclusion: In Iran, the pattern of HIV transmission is shifting from unsafe injection drug to unsafe sexual contact for forthcoming years. Also, increasing trend of HIV incidence in women is remarkable. Accordingly, HIV-prevention strategies need to be changed.

Authors: Haem Elham , Doostfatemeh Marziyeh
Published: August 2022

Introduction: The multidimensional item response theory (MIRT) model provides an ideal foundation for assessing the psychological properties of a questionnaire designed with multidimensional structure. This study aimed to present the first use of MIRT models to investigate the psychometric properties of general health questionnaire (GHQ-12) in parents of school-aged children.
Methods: A total of 1104 parents of school children-aged completed the Persian version of GHQ-12 questionnaire. One-dimensional IRT model and MIRT models with two and three factors were used to model the observed scores for each of the GHQ-12 items as a function of the subject's latent characteristics to consider the correlation between the dimensions of the questionnaire. Goodness of fit indices were reported for the three models, and the fits of items were assessed for the best model. Individual items were described in detail through item characteristic curves, and the amount of information carried by different items was presented using information curves.
Results: The MIRT analysis with three factors corresponding with anxiety depression, social dysfunction and loss of confidence provided the best account of the GHQ-12 data. The model showed that all items were fitted adequately. Items varied in their discrimination ranged from 0.94 to 2.13, 1.31 to 2.74, and 2.87 to 3.57 for social dysfunction, anxiety depression, and loss of confidence, respectively. Moreover, items 8 and 2 provided the least information in social dysfunction and anxiety depression dimensions, respectively. Items in the loss of confidence dimension carried the most information among all items of the GHQ-12.
Conclusion: The developed framework for evaluating the psychometric properties of GHQ-12 can be a suitable alternative to traditional approaches as well as unidimensional IRT models, the use of which has been restricted due to the multidimensional structure of the questionnaire.

Introduction: Coronary heart disease (CHD) is the leading cause of morbidity and mortality globally, and specially in Iran. An accurate assessment of the incidence of coronary heart disease (CHD) is very important for public health. In current study we aimed to investigate the incidence of CHD and importance of several classical modifiable and un-modifiable risk factors for CHD among an urban population in eastern Iran after 6 years follow-up.
Methods: The population of MASHAD cohort study were followed up for 6 years, every 3 years initially by phone and those who reported symptoms of cardiovascular disease (CVD) were asked to attend for a cardiac examination. An estimate of the incidence of CHD was determined with 95% confidence interval (95% CI) and multiple logistic regression analysis was performed to assess the association of several baseline characteristics with the incidence of a CHD event. Evaluation of goodness-of-fit was undertaken using ROC analysis. CHD cases were divided into four different categories: stable angina, unstable angina pectoris, myocardial infarction and sudden cardiac death.
Results: In the six years of follow-up of the Mashhad study participants, the incidence density of CHD events in men and women in 1000 person-year with 95% confidence intervals were 19.20 (8.10-30.30) and 11.60 (7.30-15.90), respectively. The areas under ROC curve (AUC), based on multiple logistic regression model of CHD outcome, was determined to be 0.783.
Conclusion: Our findings indicated that the incidence rate of coronary heart diseases in MASHAD cohort study increases with age, and our final model was able to predict approximately 78% of CHD events in this Iranian population.

Published: August 2022

Introduction: One of the most important 2015-post agendas of countries’ health systems is achieving Universal Health Coverage (UHC), so countries should monitor the activities carried out. The present study aimed to investigate the UHC status two years after Health Transformation Plan (HTP) in Iran.
Methods: This is a secondary analysis of the national household income and expenditure survey (with close 40,000 households as the survey sample). The survey was used to estimate financial protection indicators (out-of-pocket payment, catastrophic and impoverishment health expenditure) in 2016. Estimation for service coverage index provided by international databases was applied at the country level. Indicators of financial protection and service coverage were evaluated in relation to each other using the World Health Organization joint levels assessment method, which indicates UHC attainment in terms of a plot with four zones. The relationship was estimated for the entire population, first quintile, and fifth quintile in 2000, 2017, and 2030.
Results: The average per capita of OOP annually was 1,940,613 Rials (162.415 PPP int $). About 15.85% of households endured catastrophic health expenditures at the 10% threshold. The impoverishment health expenditure is about 0.6. Accordingly, Iran is on the border between zones 1 and 2 in 2017 in terms of achieving UHC and will move to zone 1 in 2030 with the current trend.
Conclusion: According to the results of this study, universal health coverage has not been achieved even despite the implementation of the HTP. Even with improved service coverage, achieving UHC by 2030 may seem impossible with the current trends.

Introduction: COVID-19 spread globally, including across the Balkans, resulting in different morbidity and mortality outcomes in different countries. The aim of this study was to review the impact of COVID-19 over 17 months with regards to pandemic progression, implemented mitigation strategies, and COVID-19 vaccination programs across the Balkan countries, while identifying any valuable pieces of information acquired serendipitously throughout the pandemic that can be implemented in future action plans.
Methods: A longitudinal ecological study was conducted across the Balkan countries from the onset of COVID-19 in these countries up until 1st August 2021. Epidemiological data was obtained from Our World in Data databases, while Ministry of Health websites for each respective country as well as local newspapers were utilized to review COVID-19-related mitigation and vaccination strategies. Comparisons of vaccination coverage, incident cases and mortality were made across neighboring countries, by converting the respective data to rates per 100,000 population for each country using Microsoft® Excel for mac (Version 16.59).
Results: More than 10 million positive COVID-19 cases and 164,470 deaths were observed across the Balkan countries up until 1st August 2021. Trends in COVID morbidity and mortality outcomes were evident across neighbouring countries. A staggered vaccination rollout was observed, with various rollout speeds, although gradual decline in both morbidity and mortality occurred.
Conclusion: Results obtained from this study strongly indicate that COVID-19 outcome for a particular country is not only dependent on the country’s own level of viral transmission, mitigations, and vaccination rates but also on neighbouring countries’ COVID-19 situation. Hence, cross-border governance action and recovery plans are recommended along with targeting vaccination hesitance.

Published: August 2022

This article aims to analyze how interviewees express their evaluations about the representations of women in advertising pieces that were the object of denunciations to the Brazilian Advertising Self-regulation Council (CONAR). We conducted three focus groups with a total of 22 participants and around 180 minutes of recorded material. For the analysis of the participants’ speech, we used the Appraisal System (MARTIN; WHITE, 2005). Results indicate a strong presence of disrespect, irony, offenses, insults and constraints in the advertising pieces analyzed. This study contributes to the reflections on advertising practices, as it shows that pieces of advertisement presenting women in scenarios of inferiority and disrespect tend to be disliked by consumers.

Resiliencia de la estructura productiva institucional: un análisis del gasto público
Authors: Hernández Mota José Luis
Published: August 2022

Se analiza el rol del gasto público en los procesos reforma estructural y de desempeño económico. El marco teórico se desarrolla en torno a los requerimientos necesarios para la transformación de la estructura productiva institucional que pueda reflejarse en crecimientos económicos sostenidos y mejoras en los niveles de bienestar. De esta manera, se destaca la importancia de la composición del gasto público y de los incentivos para el planteamiento adecuado de procesos de reformas estructurales que tengan impactos de complementariedad productiva en las actividades económicas privadas. Se concluye que la reorientación del gasto público propuesta por las reformas estructurales, realizada sin objetivos sociales y económicos y, por ende, sin capacidad de transformación de la estructura productiva institucional, ha sido clave en la limitación del crecimiento económico y en la ausencia de rentabilidad social; elementos necesarios para la transformación estructural de las economías.

Authors: Kasih Elisabeth Ngestirosa Endang Woro , Husna Mufaza , Mulia Muhammad Rizki , Fithratullah Muhammad
Published: August 2022

This study aims to delineate masculinity issues in Guy Maupassant’s Father Milon, A Duel and The Coloniel’s Ideas short stories. This study sees that the practice of masculinity in the society legitimizes the dominant position of men and justifies the subordination of the male and female population in general and other marginalized ways of being male. This study employed Stuart Hall’s representation and Gramsci’s hegemony theories to delineate masculinity in Maupassants’ three short stories. The qualitative descriptive method was applied as the data were in the form of narration and dialogues.  The short stories revealed the dominant position of men in society that justifies the subordination of the male and female population in general. Finally, with the creation of different male characters with various degree of masculine nature, Guy Maupassant in Father Milon, A Duel and The Coloniel’s Ideas tries to balance the male character he creates. Maupassant is just trying to paint pictures of different kinds the man seen in society, therefore, confirms the verisimilitude between characters in literary works and real-life characters.

Highlight ResearchThe leopard coral grouper Plectropomus leopardus was identified and analysed based on molecular approach.Genetic diversity within two regions in Gorontalo, Sulawesi successfully performed using connectivity analysis.Three haplotypes of Plectropomus leopardus from two region in Gorontalo as one of economical important marine fish species. AbstractBar-cheek coral trout (P. leopardus) is the flagship of the grouper in the live fish market in Asia. Unfortunately, the potential of the grouper is still partly produced from natural catches. Even though hybridisation activities have also started to be carried out, there still have not been many studies on the genetic diversity of these fish. The application of molecular identification has been widely applied in marine aquatic animal species, which are very likely to occur due to errors in terms of shape and colour in the morphological character. DNA information has been beneficial in efforts to the breeding program and develop grouper aquaculture activities. DNA barcoding was used for the molecular identification and haplotype analysis of P. leopardus from two locations in Gorontalo, Sulawesi, Indonesia. A total of 14 fish samples were collected from two traditional fish markets around Kwandang and Sumalata Gulf in the northern part of Gorontalo Province, Sulawesi. This study identified and found three haplotypes from both regions. Molecular identification using Cytochrome c Oxidase subunit I (COI) gene region on mitochondrial DNA. Besides Mega7 for phylogenetic reconstruction, the data analysis using DnaSP6, Arlequin Ver.3.5.2.2, and Network 5.0.1.1. The first Haplotype is a mixed population between the Kwandang Gulf and the Sumalata Gulf, then the Kwandang Gulf haplotype and the Sumalata Gulf haplotype. The genetic distance between Kwandang Gulf haplotype and Sumalata Gulf haplotype is 0.003984, classified as a shallow genetic distance and needs more samples from another region to figure out leopard coral grouper around Indonesia.

Damage to the muscle and gill tissue of koi carp infected with E. tarda

 
Abstract
The problem that fishes farmers often face is disease. Maggot contains a high protein which ranges from 41-42%. Besides that, maggot also has a good effect on increasing the body resistance of fish. While the maggot provision fulfills nutritional need, it’s also expected to boost immunity against bacterial disease. One of which is Edwardsiella tarda, known to infect koi carp (Cyprinus carpio). Feeding of maggot flour at different doses, namely A (25%), B (50%), C (75%), and D (100%) was carried out to determine its effect on the histopathology of the muscles and gills of C. carpio infected with E. tarda. Water quality during the study obtained an average value, namely the temperature ranging from 26-27.5℃, pH 6.5-8.1, and DO 5.2-8 mg/L. Fish infected with E. tarda showed several clinical symptoms, including rapid operculum movement, irregular and slow swimming, and bleeding on the skin. The results of the histopathological analysis showed that in muscle and gill tissue, treatment C (75%) showed the lowest damage value among other treatments with an average score of necrosis 0.93, hyaline degeneration 1.33, and Edema 1.27. Average score of gill tissue damage was 0.9 fusion, 1.3 congestion, 0.9 hyperplasia. Based on this, the provision of maggot flour can be used to prevent infection of E. tarda against C. carpio.

This is the first stable isotopes study of rays from Malaysian waters
Urea extraction significantly enriched the δ15N values (‰)
Urea removal is obliged for stable isotope studies on rays
Such methodological information is critical for marine research in the region

 
Abstract
This is the first reported record of stable isotope values for elasmobranch rays within Malaysian waters, and serves as an important baseline methodological information for future studies investigating stable isotope values in both shark and ray species in the region. This study examined the effects of urea removal on the stable isotopes values of δ13C and δ15N in muscle tissues sampled from several elasmobranch rays species, namely Pastinachus atrus, Rhinoptera javanica, Himantura gerrardi, Himantura uarnak and Aetobatus ocellatus. Individual ray species were collected in July and August of 2018, from the coastal waters of Terengganu State, Malaysia. Urea removal was performed by soaking muscle tissue samples in deionised water for at least 24 hours before being dehydrated. The resulting stable isotope values of these samples were compared to samples that did not undergo the urea removal process. Stable isotope values were individual and species-specific, however, the effect of urea removal was significant for δ15N values but did not significantly affect the δ13C values. We conclude that removing urea from elasmobranch samples before stable isotope analysis is advisable to draw correct conclusions about the animal’s diets.

Abstract
Malaria is an infectious disease caused by protozoan parasites of the genus Plasmodium that categorized as deadliest diseases in the world. Artemisinin and its derivatives are still recommended drugs for malaria therapy, however, there have been indications that Plasmodium parasites are resistant to this drug. Therefore, a study on polysaccharides from microalgae may be a potential as bioactive compound for anti-malaria. The aim of this study was to determine the effectiveness of the mixed microalgae polysaccharides as anti-malarial in vitro. Polysaccharides were extracted from three microalgae Spirulina sp., mixed microalgae Glagah and mixed microalgae East Java using the alkaline extraction method. The anti-malarial activity test refers to the concentration of polysaccharides used in calculating the IC50 value by probit analysis.  The concentration of polysaccharides of the three microalgae used were 0; 0.01; 0.01, 1, 10 and 100 µg/mL. The results showed that the IC50 values of polysaccharides of Glagah, Spirulina sp. and East Java microalgae were 3.18 µg/mL, 5.43µg/mL, and 9.87 µg/mL, respectively. In Conclusion, polysaccharides of Indonesian mixed microalgae can be promoted as anti-malarial.

Autoclaving for 3x3 hours followed by alkaline hydrolysis (3x3AH) may lower nano-calcium particle size into 47.47 nm
3x3AH sample contain 30.73% calcium and 18.37% phosphorus
3x3AH sample created the best calcium solubility (26.14 %) in comparison to synthesized CaCO3 (14.34 %)
Grouper nano-calcium powder includes trace quantities of organic content, such as protein and fat, which enhance calcium's solubility.

 
Abstract
Fish bone nano-calcium production may solve two challenges, providing calcium for lactose-intolerant people and recycling bone waste. Fish bone autoclaving prior to extraction reduces fat, denatures collagen, and softens bones but only few researches have compared autoclaving duration with nano-calcium product quality, particle size, and its solubility in in vitro testing. This study studied the influence of autoclaving duration followed by alkaline hydrolysis on nano-calcium characteristics to enhance calcium solubility in in vitro gastrointestinal simulation experiments. The dried grouper (Epinephelus sp.) bone was divided into four groups: 0A (no autoclaving), 3A (3 h autoclaving), 2x3A (double cycle for 3 h autoclaving), and 3x3A (triple cycle for 3 h autoclaving). Each group was followed by alkaline hydrolysis, designated as 0AH, 3AH, 2x3AH, and 3x3AH. The results showed that autoclaving for 3x3 hours followed by alkaline hydrolysis resulted in lowest nano-calcium particle size of 47.47 nm consisting of 30.73% calcium and 18.37% phosphorous. 3x3AH sample created the best calcium solubility (26.14%) in comparison to synthesized CaCO3 (14.34%). In contrast to synthetic CaCO3, grouper nano-calcium powder includes trace quantities of organic contents, such as protein and fat, which enhance calcium solubility. In vivo research should be established to study the bioavailability and influence of grouper nano-calcium powder on bone density.

Cardiac monitoring based on wearable photoplethysmography (PPG) is widespread because of its usability and low cost. Unfortunately, PPG is negatively affected by various types of disruptions, which could introduce errors to the algorithm that extracts Pulse Rate Variability (PRV). This study aims to identify the nature of such artifacts caused by various types of factors under the conditions of precisely planned experiments. We also propose methods for their reduction based solely on the PPG signal while preserving the frequency content of PRV. The accuracy of PRV derived from PPG was compared to Heart Rate Variability (HRV) derived from the accompanying recorded ECG. The results indicate that filtering PPG signals using the Discrete Wavelet Transform and its inverse (DWT/IDWT) is suitable for removing slow components and high-frequency noise. Moreover, the main benefit of amplitude demodulation is better preparation of the PPG to determine the duration of pulse cycles and reduce the impact of some other artifacts. Postprocessing applied to HRV and PRV indicates that the correction of outliers based on local statistical measures of signals and the AR model is only important when PPG is of low-quality and has no effect under good signal quality. The main conclusion is that DWT/IDWT, followed by amplitude demodulation, enables the proper preparation of the PPG signal for the subsequent use of PRV extraction algorithms. However, postprocessing in the proposed form should be applied more in the situations of observed strong artifacts than in motionless laboratory experiments.

Published: August 2022

Cyber-Physical Systems (CPS) are integrations of computation and physical processes. Physical processes are monitored and controlled by embedded computers and networks, which frequently have feedback loops where physical processes affect computations and vice versa. To ease the analysis of a system, the costly physical plants can be replaced by high-fidelity virtual models that provide a framework for Digital-Twins (DT). This paper aims to briefly review the state-of-the-art and recent developments in DT and CPS. Three main components in CPS, including communication, control, and computation, are reviewed. Besides, the main tools and methodologies required for implementing practical DT are discussed by following the main applications of DT in the fourth industrial revolution through aspects of smart manufacturing, sixth wireless generation (6G), health, production, energy, and so on. Finally, the main limitations and ideas for future remarks are talked about followed by a short guideline for real-world application of DT towards CPS.
