Feasibility of Artificial Intelligence–Based Electrocardiography Analysis for the Prediction of Obstructive Coronary Artery Disease in Patients With Stable Angina: Validation Study (Preprint)
Authors: Park Jiesuck , Yoon Yeonyee , Cho Youngjin , Kim Joonghee
Published: May 2023

BACKGROUND

Despite accumulating research on artificial intelligence–based electrocardiography (ECG) algorithms for predicting acute coronary syndrome (ACS), their application in stable angina is not well evaluated.

OBJECTIVE

We evaluated the utility of an existing artificial intelligence–based quantitative electrocardiography (QCG) analyzer in stable angina and developed a new ECG biomarker more suitable for stable angina.

METHODS

This single-center study comprised consecutive patients with stable angina. The independent and incremental value of QCG scores for coronary artery disease (CAD)–related conditions (ACS, myocardial injury, critical status, ST-elevation myocardial infarction, and left ventricular dysfunction) for predicting obstructive CAD confirmed by invasive angiography was examined. Additionally, ECG signals extracted by the QCG analyzer were used as input to develop a new QCG score.

RESULTS

Among 723 patients with stable angina (median age 68 years; male: 470/723, 65%), 497 (69%) had obstructive CAD. QCG scores for ACS and myocardial injury were independently associated with obstructive CAD (odds ratio [OR] 1.09, 95% CI 1.03-1.17 and OR 1.08, 95% CI 1.02-1.16 per 10-point increase, respectively) but did not significantly improve prediction performance compared to clinical features. However, our new QCG score demonstrated better prediction performance for obstructive CAD (area under the receiver operating characteristic curve 0.802) than the original QCG scores, with incremental predictive value in combination with clinical features (area under the receiver operating characteristic curve 0.827 vs 0.730; P<.001).

CONCLUSIONS

QCG scores developed for acute conditions show limited performance in identifying obstructive CAD in stable angina. However, improvement in the QCG analyzer, through training on comprehensive ECG signals in patients with stable angina, is feasible.

A potential alternative fuel option is biodiesel, which is produced mostly from natural resources due to the limited availability of petroleum supplies and environmental issues. Waste cooking oil (WCO) containing a high concentration of free fatty acid (FFA) can be transformed into biodiesel, which substantially benefits the environment and for reducing the fuel . The use of smectite clay as a catalyst in the esterification reaction of WCO with methanol was studied. Smectite was chemically activated by sulfuric acid (H2SO4) to obtain the acid-modified smectite. The utilization of an acid-catalyzed esterification procedure as a pre-treatment for WCO for biodiesel synthesis has been studied in some detail. However, there aren't many effective ways to optimize this operation. The process variables used in this study's esterification of FFAs in WCO were optimized using a Box-Behnken design (BBD). At atmospheric pressure, the catalyst amount of 5.03 wt%, the methanol to WCO molar ratio of 22.38, and the reaction time of 3.01 h are the optimal running parameters for accomplishing 97.96% FFA conversion. The catalyst was employed five times in a row without noticeably lowering its catalytic effectiveness. The results showed that smectite clay is an essential, low-cost, and recyclable catalyst for the esterification of FFA in WCO.

Published: May 2023

One of the most prospective oil and gas producing basins in Indonesia is Kutai Basin which is located in East Borneo. In Kutai Basin there is a natural resource potential in the form of gas which is quite abundant. This is due to the richness of the source rock aspect in the Kutai Basin which is dominated by coal. Besides coal, in the Kutai Basin there is also claystone with rich organic matter (organic shale) that has an important role as a prospective source rock. Therefore, a final project research was conducted in the Kutai Basin, East Kalimantan. The purpose of the research is to identifying the type and content of subsurface lithology and fluids, calculating petrophysical parameters, and making the facies distribution map at the research site in potential and prospective zone to produce hydrocarbons which is called the zones of interest. The research is focused on reservoir rocks at the research site because the hydrocarbons accumulated in the reservoir rocks itself. By focusing research on reservoir rocks, it will be able to describe the modelling and calculation results of petrophysical parameters using several analytical methods such as qualitative and quantitative analysis methods, electrofacies and parasequence analysis methods, stratigraphic correlation analysis methods, facies analysis methods and depositional environments, and facies map analysis methods. In addition, by focusing research on reservoir rocks, it can develop and increase the level of optimization of exploration and exploitation of drilling wells. Based on the analysis data, the research location is included in the transitional depositional environment, delta in particular with distributary channels and mouth bars facies and also it can be identified some lithology such as sandstone, claystone, coal, limestone, and organic claystone and there are fluids with gas and water types.

Authors: Azka Faradila , Hendrawan Donny
Published: May 2023

Intelligence plays a significant role in determining the severity of Autism Spectrum Disorder (ASD), thus understanding intelligence among children with ASD is important to guide planning of appropriate interventions. Scores on IQ tests as well as intelligence sub-components between ASD and typically developed (TD) children, reflect distinct underlying cognitive processes. Therefore, a comprehensive investigation of the neuropsychological aspects of children ASD may better refine our understanding of the cognitive abilities among children with ASD. The current cross-sectional study investigated differences in intelligence profiles and executive function among children with TD children and children with High-Functioning Autism Spectrum Disorder (HFASD). A total of 34 participants met criteria for inclusion with 24 participants in the TD group, and 10 in the HFASD. Some of the measures which were used included the SB-LM, Executive Function Indonesia (EFI), and Autism Spectrum Quotient: Children's Version (AQ-Child). Data were analysed using Spearman correlation and Mann-Whitney test. Results showed no differences in the intelligence profile in both groups, yet significant differences were found in the composite EF, Inhibitory Control, and Cognitive Flexibility. Additionally, there was a difference in the correlation of intelligence and EF variables between the two groups. Thus, it can be concluded that both groups show qualitatively different cognitive processes. A recommendation derived from these results is that comprehensive EF assessment and treatment should be conducted as part of the global evaluation of ASD patients, primarily to design an intervention to enhance their academic domain.

Published: May 2023

Adverse Childhood Experience (ACE) has a significant impact on people’s lives. Few studies have been conducted on young parents with ACE in Indonesia, of which indicated that parenting stress is more common in young parents with ACE.The gap between resources, expectations, and negative mental judgment in response to differences lead to parental stress. The purpose of this research is to explore parenting experiences among young adults with ACE, specifically understanding how they cope with stress. This qualitative study adopted a snowball sampling (Yin, 2016) to identify six participants who are currently a parent with ACE. This research employed a phenomenological qualitative design (Yin, 2016). In-depth interviews are the primary data collection and data was analysed with a thematic analysis. The result indicated that ACE has a significant influence on current parenting stress experiences. Religiosity was found to have an essential role in coping with parenting stress. Cultural standard is a significant characteristic of a nation’s culture, impacting an individual’s thought patterns, emotions, and behavior. Religiosity is an appreciation of a specific religion that helps overcome parenting stress. The ability to overcome this situation, find personal growth, and appreciate life and spiritual changes is called post-traumatic growth.

Published: May 2023

Abstract: Drug Eluting Stents (DES) are small, expandable tubes that are implanted into a diseased, blocked peripheral or coronary artery through angioplasty to widen and increase the blood flow by slowly releasing the drug from device. They are covered in a medication that stops scar tissue from expanding upon that artery. In medical practice DES are frequently used for vascular disorders, exhibiting adequate potency and suitability within the acceptable range. Medical device regulations in European Union (EU) are covered by Directives 93/42/EEC, 98/79/EEC and 90/385/EEC which were recently replaced by new regulations (EU) 2017/745 on medical devices and (EU) 2017/746 on In vitro diagnostic medical devices. Across all the EU legislation, “CE Mark” or “Certificate of Compliance” has become a recognised term. The Competent authority’s (CA) certifies that a product conforms to required standards of EU, then the manufacturer display the “CE mark” on the label. The DrugDevice combination products like DES are included in Class-III high risk active implantable medical devices. The pre-clinical investigations of drug eluting stents often follow International Organization for Standardization (ISO) requirements, these vascular stents are covered under ISO 25539-2: 2020 - Cardiovascular Implants - Endovascular Devices, ISO 10993:2018- Biological Evaluation of Medical Devices and ISO 10555-1: 2013 – Intravascular catheters, sterile and single use medical devices.

Published: May 2023

Abstract: Steganography refers to the concealment of confidential data within a common medium, like a text, image, or audio file, without altering its original appearance, to evade detection. This method is used for several purposes, including protecting data privacy, preventing unauthorized access to data, and ensuring safe information transmission over insecure networks. While steganography can be used for legitimate purposes such as by military, law enforcement, and journalism, it can also be employed for malicious activities like cybercrime and terrorism. The least significant bit (LSB) of each letter in text & audio and the LSB of each pixel in images are altered in steganography to make the alterations invisible. Advanced steganography algorithms like Masking & Filtering and Encrypt & Scatter have improved security against steganalysis assaults while producing higher-quality stego images. The method’s capability for concealing text with an unlimited hidden text size in text, audio, and images will be employed in the outcome.

Abstract: One of the best payment methods that clients may use to conduct transactions effortlessly and boost their purchasing power is a credit card. In addition, it is incredibly simple to use and provides a number of benefits, like cashback and reward points. However, the primary issue is credit card fraud, which is fast rising every day. The most common type of identity theft worldwide is still credit card fraud. The use of credit cards has grown too dangerous in recent years. In reality, there are many other kinds of credit card fraud, including phishing and vishing, keystroke logging, POS fraud, application fraud, loss of card or theft, and POS fraud and vishing. However, the person should take safety steps and safeguards to protect his or her money. The vast bulk of this fraud is being committed by organized crime rings, whose operations have been industrialized and computerized. So how may these frauds be found? Utilizing machine learning algorithms is the solution. Conventional fraud detection is another method, however, machine learning algorithms are much more accurate and exact. The basic objective is to create a model that can foretell whether a Transaction will be fraudulent or not. In this project, predictive models utilized in this research include Artificial Neural Networks, Random Forests, Support Vector Machines, KNN, Decision Trees, Gaussian Naive Bayes, and Logistic Regression. The results from each of these models are evaluated for accuracy, and the best model is selected.

Objectives The purpose of this study was to investigate the effect of smartphone addiction of parents with elementary school children on marital conflict and to explore the structural relationships among smartphone addiction of parents, marital conflict, parental involvement, and media device addiction of their children who go to elementary school.
Methods A total of 1,224 pairs of data from the 13th Korean Children's Panel Study (2020) were analyzed with Actor-Partner Interdependence Model (APIM). In order to compare the actor and the partner effect of smartphone addiction, an equivalence constraint model was set up and difference verification was conducted. Also, a structural equation analysis method based on the maximum likelihood method (ML) was used to verify the structural relationship among parental smartphone addiction, marital conflict, parental involvement, and elementary school students' addiction to media devices.
Results The results are as follows: first, both mother’s and father’s smartphone addiction had a positive actor effect on the marital conflict, but a positive partner effect was only confirmed from mother’s smartphone addiction. Second, the actor effect of smartphone addiction on marital conflict was found to be greater in father than mother, however, the partner effect of father's smartphone addiction on marital conflict perceived by mother was greater than the partner effect of mother's smartphone addiction on marital conflict perceived by father. Third, mother's smartphone addiction was influenced through how she perceived marital conflict and parental involvement on students' media device addiction, while father's smartphone addiction was influenced sequentially by mother's perceived marital conflict and parental involvement on students' media device addiction.
Conclusions This study suggests that both mother and father's smartphone addiction affect to elementary school students' media device addiction, but the mechanisms affecting on media device addiction from parents are different.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Jeon Ji-Hye
Published: May 2023

Objectives This study aims to specify what to consider when teaching the upper level of the elementary recommended vocabulary.
Methods Vocabularies extracted from textbooks reflecting the 2015 curriculum and CEFR textbooks were described levels of EVP to investigate learners’ vocabulary awareness and the aspect of vocabulary being implemented in textbooks was analyzed. Vocabulary awareness survey items were confirmed through a preliminary survey targeting 20 students at Gunsan J elementary school. 27 survey items described by CEFR levels in EVP were analyzed in terms of usage in one type of Korean textbooks. Vocabulary awareness survey was conducted with 116 students of Gunsan J elemenatry school using a google survey.
Results 12 vocabularies out of 27 have some usage in textbooks. The vocabulary awareness of the learners for the vocabulary usage described in the textbook was shown high. Although textbooks use only some usages of vocabulary, learners responded that they know other usages as well. Awareness of upper level vocabulary usage, not the CEFR Basic User, was also shown high.
Conclusions Vocabulary awareness items that can be used in the classroom should be developed. EVP can be a basis for users to search for and utilize vocabulary usage to develop survey items. Since the results can be interpreted as the CEFR learner’s language proficiency, it can be effective tool for evaluating, analyzing and utilizing the learner’s vocabulary awareness. It is necessary to actively introduce various uses of vocabulary in elementary vocabulary instructions. In many cases, learners knew the usage of upper level's vocabulary usage even if those weren't used in textbook and weren't classified to the elementary recommended in curriculum. Therefore, Efficient vocabulary instruction will be possible, if the recommended vocabulary in the curriculum is used as a guideline, and vocabulary usage is taught in the class based on learners’ vocabulary awareness.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Choi Sun-Young , Kim Bong Whan
Published: May 2023

Objectives The purpose of this study is to understand domestic violence victims' participation experiences in a restorative conversation meeting conducted by the police and its meaning.
Methods This study was conducted based on a paradigm in qualitative research methodology, and it was carried out through qualitative case study methodology among them.
Results The study participants were two domestic violence victims who had reported to 112 and participated in a restorative conversation meeting, and an in-depth interview was carried out with them. Its analysis method was first developed to reveal a meaningful topic for each case through intra-case analysis, and categorization was attempted through inter-case analysis. The categorization resulted in six supercategories and seventeen subcategories. The domestic violence victims’ participation experiences in a restorative conversation meetingled to the supercategories: wanting to depend on public power, considering it as a last chance, building psychological stability, time to face each other's positions and situations, looking straight at grown-up self, and perpetrators’ showing a positive change. The study results presented subsequent changes and an inter-case analysis which summarized the meaning of their common experiences by topic.
Conclusions In this study, the victims participated in the restorative conversation meeting in the hope that the public power would change the perpetrators through a restorative conversation meeting conducted by the police and with the feeling of grasping at straws, and in the participation process, they were gradually giving meaning as an experience of growing themselves from a weak position to an equal relationship with the perpetrators. It was possible to interpret this as an improvement in the victims’ ability to view the situations, cope with them, and control a conflict while experiencing a process of insight to understand the others and themselves. Finally, for internal growth and damage recovery of domestic violence victims, suggestions for revitalizing restorative conversation meeting and the necessity for policy efforts at national level were discussed.

The results of the study revealed that total polyunsaturated fatty acid (PUFA) (32.37%–37.05%) values were higher than those of total saturated fatty acids (SFA) (29.96%–31.76%) and monounsaturated fatty acid (MUFA) (17.26%–20.81%) in all whole muscle (WM) and different regions (D, V, and C) of the pike perch. The highest SFA, MUFA, and PUFA amounts were in D, WM, and D regions, respectively. In all groups, the amount of Docosahexaenoic acid (DHA) (12.97-15.43%) was higher than Eicosapentaenoic acid (EPA) (5.66-6.97%). While there was no difference between regions in terms of EPA value, the difference between regions in terms of DHA values was found to be important (p <0.05). The highest EPA and DHA values were detected in the D region. Atherogenicity index (AI) (0.47–0.48), thrombogenicity index (TI) (0.33–0.35), hypocholesterolemic/hypercholesterolemic ratio (H/H) (1.53–1.57) and n-6/n-3 (0.47–0.51) ratios were at recommended levels in all regions (WM, D, V, and C) and there was no regional difference (p > 0.05). The results showed that the fatty acid composition of the pike perch varies according to different body regions, it is rich in nutrient content and has the recommended level of AI, TI, H/H, and n-6/n-3 ratios. It can be concluded that pike perch has beneficial health effects on human nutrition.

Schwannoma is benign tumor that can occur in any part of the nerve that contains a Schwann cell. It is rare in the head and neck region and is characterized by common postoperative neurologic symptoms. We experienced a cervical schwannoma in a 22-year-old young man. Except for a foreign body sensation in the neck and a mass in the anterior region, there were no other complaints. A retropharyngeal schwannoma was most suspected considering neck computed tomography, magnetic resonance imaging, laryngoscopy and fine needle aspiration. Surgical treatment was performed, and the origin of the schwannoma was diagnosed as the tonsillar branch of the glossopharyngeal nerve. Histopathological examination confirmed the presence of a schwannoma with typical characteristics. After surgery, the patient recovered without any side effects. We report this case with a review of the literature.

The problem of the paper focused on the role of the integration of strategic planning for tourism development and air transport connectivity is integral to advancing Indonesia’s tourist destinations with world-class marine park attractions spread across several eastern provinces that have not been visited by tourists optimally. They were relying on opening flight paths connected to the main entrances to Jakarta and Bali airports. This research aims to uncover and analyze the strategic planning of tourism development in Sulawesi Utara Province. A mixed method was used in research that adopted the model of Golkar (2005) with 96 questionnaires to officials of the tourism office, airport authorities, and airlines. An analysis using a four-dimensional SWOT (strengths, weaknesses, opportunities, and threats) analysis (Mercer, 1991). The findings show that the accessibility of air transportation for tourist visits is limited and is not integrated with the flight paths of tourists. Tourism development planning in Sulawesi Utara Province tends to be partial and not consider critical variables. Such as the development of air transport infrastructure to open access to tourist destinations that are difficult to reach by land and sea transportation. Contribution to the theory and managerial implications are discussed, and suggestions for further research are given.

Speech is the most familiar and habitual way of communication used by
most of us. Due to speech disabilities, many people ﬁnd it diﬃcult to
properly voice their views and thus are at a disadvantage. The re-
search tackles the issue of lack of speech from a speech impaired user
by recognizing it with the use of ML models such as Gaussian Mixture
Model - GMM and Convolutional Neural Network - CNN. With properly
recorded and cleaned muscle activity from the facial muscles it is
possi- ble to predict the words being uttered/whispered with a certain
accuracy. The intended system will additionally also have a visual aid
system which can provide better accuracy when used together with the
facial muscle activity-based system. Neuromuscular signals from the
speech articulat- ing muscles are recorded using Surface
ElectroMyoGraphy (SEMG) sen- sors, which will be used to train the
machine learning models. In this paper we have demonstrated various
signals synthesized through the ElectroMyography system and how they can
be classiﬁed using machine learning models such as Gaussian Mixture
Model and Convolutional Neu- ral Network for the visual-based
lip-reading system.

The WHO Unity Studies initiative engaged low- and middle-income
countries in the implementation of standardized SARS-CoV-2
sero-epidemiological investigation protocols and timely sharing of
comparable results for evidence-based action. To gain a deeper
understanding of the methodological challenges faced when conducting
seroprevalence studies in the Africa region, we conducted unstructured
interviews with key study teams in five countries. We discuss the
challenges identified: participant recruitment and retention, sample
frame, sample and data management, data analysis and presentation to
policy makers. Potential solutions to aid future implementation include
preparedness actions such as the development of new tools, robust
planning and practice.
In vitro Anti-Metastatic Combination of the Naturally Occurring Chlorogenic Acid with Different Chemotherapies on Hepatocellular Carcinoma

Published: May 2023

Background: Cancer metastasis is deemed to be the principal
cause of cancer death worldwide. Cancer therapy is actively evolving,
but cancer-related mortality is still fearful. Although the
currently-used cancer protocols could show anti-cancer efficiency; these
protocols still lack specific anti-metastatic components. Aim:
To test the efficiency of adding a naturally-occurring chlorogenic acid
(CGA) to the three commonly used chemotherapeutics, 5-fluorouracil
(5-FU) and doxorubicin (DOXO), and cisplatin (CIS) in preventing
metastatic potential on HepG2 cell line. Methods: After
treating HepG2 with CGA alone or with 5-FU, DOXO, and CIS, the cellular
lysate content of alpha-fetoprotein (AFP), metalloproteinases (MMP-3,
MMP-9, and MMP-12), nitric oxide (NO), migration scratch assay and the
gelatinolytic activity against a non-treated group were estimated.
Results: The treatment with CGA significantly reduced the
levels of AFP and NO; along with the tested matrix metal­loproteinases,
decreased gelatinolytic and migration activity in comparison to the
non-treated HepG2 group (representative of hepatocellular carcinoma).
CGA and CIS were more powerful than DOXO in the inhibition of cell
migration (metastasis). However, the addition of CGA to CIS, DOXO, and
5-FU inhibited the cellular migration (metastasis) more than 5-FU alone.
Conclusion: CGA showed a promising anti-metastatic activity
when added to the studied chemotherapeutic drugs.
