The main sacramentological provisions in the discourse of theological personalism: On the example of the heritage of Orthodox theologians of the 20th — early 21st centuries
Authors:   Saints Cyril and Methodius Institute for Postgraduate Studies, Budyanskiy Valery S.
Published: October 2024

The article examines the key provisions of the interpretation of the Orthodox sacramentology in the context of theological personalism. The author explores the specifics of the view of some representatives of theological personalism on Orthodox sacramentology. The introduction describes the research methodology, identifies the core problem of the research, and offers an introduction to the terminology adequate to the subject of the study. The main section is devoted to two components of the personalist vision of Orthodox sacramentology — the idea of the sacrament itself and specific sacramentological constructs contained in the theological heritage of a number of representatives of the discourse. Studying the texts of a number of Orthodox theologians of the 20th — early 21st centuries, developing or relying on the ideas of personalism, leads to the several conclusions. Within the heterogeneous direction of thought of theological personalism, there are a number of significant provisions of the doctrine of the sacraments: sacramentology is based on a personalistically understood soteriology; the exceptional importance of the social aspect of the sacramental life of the Church is emphasized, which is called upon to reveal the Church itself and create a space for genuine dialogue, that is, to transform human existence, elevating it to the personal dimension. Individual sacraments are understood as a means for a Christian to become a person through overcoming the individual and natural, joining the space of genuine dialogue (understood in a social or mystical key), and mastering the correct way of interacting with the world and the Other.

Published: October 2024

Introduction

This research focuses on the concept of integrating Radial Basis Function Networks with deep learning models to solve robust regression tasks in both transportation and logistics.

Methods

It examines such combined models as RNNs with RBFNs, Attention Mechanisms with Radial Basis Function Networks (RBFNs), and Capsule Networks with RBFNs and clearly shows that, in all cases, compared to the others, the former model has a Mean Squared Error (MSE) of 0.010 to 0.013, Mean Absolute Error (MAE) – 0.078 to 0.088, and R-squared (R2) – 0.928 to 0.945, across ten experiments. In the case of Attention Mechanisms with RBFNs, the models also demonstrate strong performance in terms of making predictions. The MSE ranges from 0.012 to 0.015, the MAE from 0.086 to 0.095, and the R2 from 0.914 to 0.933.

Results

However, it is critical to note that the Capsule Networks with RBFNs outperform other models. In particular, they offer the lowest MSE, which is between 0.009 and 0.012, the smallest MAE, which ranges from 0.075 to 0.083, and the highest R2, from 0.935 to 0.950.

Conclusion

Overall, the results indicate that the use of RBFNs in combination with different types of deep learning networks can provide highly accurate and reliable solutions for regression problems in the domain of transportation and logistics.

The income of the population of a society is important for welfare because it influences its ability to meet basic needs. In Malang Regency there are around 2,685,900 people with a GDP per capita of 43.73 million rupiah in 2022. This research applies a quantitative approach. The research results show that the Covid-19 pandemic, rising fuel prices, low levels of education, people's mindsets that care less about education, economic limitations, lack of employment opportunities, and climate conditions are the causes of the high number of poor people, low levels of education, and low levels of poverty. high open unemployment. The impact is an increase in crime, limited access to education, high levels of unemployment, poverty, and a decline in prosperous economic conditions. Apart from these factors, education has a significant influence on people's income. Community income is not significantly influenced by the number of poor people and the level of open unemployment. The Malang Regency Government has implemented various programs to overcome these challenges, including Indonesian Economic Heroes (PENA), creating opportunities for small and medium enterprises (MSMEs), the Malang Makmur equality education movement program (GERTAK Malang Makmur), the Smart Indonesia Card (KIP), labor-intensive programs, job training programs, and the Pre-Employment Card Program.

Authors: Ardhi Lukitasari Ayu Galuh , Martini Heny , Rahimah Anna Fuji
Published: October 2024

Background: In Indonesia, pulmonary hypertension prevalence is 1:10.000 population. Due to its atypical symptoms, often PH patients come as a late presenters thus they have a worse prognosis. The golden standard to diagnose is Right Heart Catheterization (RHC) which is not widely available. Objectives: To generate a scoring system based on clinical presentation, electrocardiogram, and chest x-ray for early detection. Methods: A hospital-based cross-sectional survey was conducted in RSUD dr. Saiful Anwar, East Java from July 2020 – November 2023 with data from the medical record in which all variables are obtained at one period. Data were analyzed using bivariate analysis, multiple logistic regression, and Area Under Curve (AUC) from Receiver Operating Characteristic (ROC). Results: A total of 244 patients who were above 18 years old were conducted RHC at RSUD dr. Saiful Anwar East Java. We found a total score of 12 consisting of Dyspnea on Effort (DOE) score 2, Palpitation score 1, Increasaed P2 score 2, Increased JVP (Jugular vein pressure) score 2, RV (Right Ventricular) Heaves score 2, Right bundle branch block (RBBB) score 1, and Cardiomegaly (CTR >50%) score 2. With a 2 x 2 table, we found that a score of ⩾5 is likely for pulmonary hypertension diagnosis. Conclusion: Our study is a predictive model with a scoring system that has good sensitivity and specificity in selected populations where one of its limitations is sampling bias thus cannot yet be applied to the general population and needs further research for validation.

How to decide appropriate percutaneous coronary intervention (PCI) technique for managing heavy calcified coronary lesions: serial case-report
Authors: Caesario Fahreza , Rohman Mohammad Saifur
Published: October 2024

Background: Coronary artery calcification (CAC) is still challenging for interventional cardiologists. Their contribution to major adverse cardiac events occurs from the high risk of stent thrombosis or in-stent restenosis and target lesion revascularization. Optimal preparation, such as coronary plaque modification before stenting, is required to reduce the risk of periprocedural adverse events. This case presentation aimed to describe the appropriate management of heavy calcified coronary lesions. Case Presentation: Two cases of heavy calcified coronary lesions with different baselines as Acute Coronary Syndromes (ACS) and elective PCI were presented. In our ACS patients, the Primary PCI was done by coronary angioplasty without stenting because of the complexity of the heavily calcified lesion. A referral to tertiary health care was made for further PCI procedures using a combination of calcium-ablation and balloon-based techniques. A treatable complication occurred after the orbital atherectomy was performed with good results. The second case was an elective PCI patient with heavy calcified lesions findings from coronary angiography. The balloon-based technique was performed using non-compliant and scoring balloons without complication and showed good results. Conclusion: The challenging points in managing heavy calcified coronary lesions are procedure complexity and the higher stent failure rate. Many modifying coronary calcification algorithms using advanced modalities have been proposed, which could be used to select the appropriate technique as experienced and increase the success rate.

Authors: Nugroho Ira Vori , Kurnianingsih Novi
Published: October 2024

Background: Chronic limb-threatening ischemia (CLTI) is a very morbid illness that significantly reduces quality of life. The severity of this disease may necessitate revascularization or amputation. Arteriography is frequently performed for the planning of revascularization. Patients with compromised kidney function need alternative contrast agents. CO2 may be utilized in lower extremity vascular diagnostics and intervention, especially in patients at risk for contrast-induced nephropathy (CIN). Case Illustration: An 80-year-old female with bilateral leg pain and leg swelling had an ulcer on her toe for 2 weeks. She had a history of intermittent claudication for 1 year, hypertension for 5 years, kidney stones for 2 years, and chronic kidney disease for 1 year. She underwent an ECG, laboratory, USG, DUS, and CT-angiography examination. From her laboratory result, her initial creatinine was 5.02 mg/dL (eGFR 8 mL/m/1.73 m2). After good hydration, it became 1.28 mg/dL (eGFR 39 mL/m/1.73 m2). After a CT-angiography procedure, her creatinine level was increased (3.7 mg/dL; eGFR 10.9 mL/m/1.73 m2). She was diagnosed with CLTI Rutherford V Fontain 3 left lower extremity. She suggested doing an angioplasty procedure with a safer contrast agent. An angioplasty procedure was done at RSSA Malang with CO2 contrast. After the procedure, her leg pain improved, and her creatinine didn’t elevate. Conclusion: CO2 angiography might be used as a safe alternative contrast medium in patients with CLTI, which benefits the preservation of renal function and prevents limb amputations.

SGLT2 inhibitor, a new bullet in heart failure management
Authors: Saidi Zaki , Widito Sasmojo
Published: October 2024

The global health landscape is confronted with substantial challenges stemming from diabetes mellitus and heart failure (HF). The escalating incidence of diabetes mellitus (DM), in correlation with HF, underscores the imperative necessity for efficacious strategies in the realm of prevention and management. The most recent advancements in therapeutic approaches, specifically Sodium-glucose transporter 2 inhibitors (SGLT2i), present a promising prospect for enhancing outcomes and addressing the existing gaps in HF management. This paper aims to elucidate the significance of SGLT2i in the therapeutic management of both reduced and preserved heart failure, with or without the presence of DM. SGLT2i are new heart failure drugs. In trials, SGLT2i improved diastolic dysfunction, reduced oxidative stress, inflammation, fibrosis, and myofilament rigidity. The first SGLT2 inhibitor studies, EMPA-REG OUTCOME, DECLARE-TIMI 58, and CANVAS, showed that Empagliflozin and Canagliflozin reduced HF mortality and rehospitalization in type 2 diabetes mellitus (T2DM) patients. Dapagliflozin reduces HF hospitalizations without impacting T2DM mortality. Canagliflozin avoided creatinine rises, kidney disease deaths, and cardiovascular deaths in the CREDENCE Study. SGLT2i improve health in heart failure with preserved ejection fraction (HFpEF). SGLT2i improved health status statistically in the PRESERVED-HF and EMPEROR-Preserved investigations. SGLT2i became known as a promising therapeutic choice in the treatment of HF. The substantial evidence from prominent large-scale clinical trials has substantiated the cardiovascular and renal protective effects of SGLT2i. Furthermore, the benefits of these medications are relevant for individuals who have been diagnosed with heart failure with reduced ejection fraction (HFrEF), as well as those who are experiencing heart failure with preserved ejection fraction (HFpEF).

Cancer remains a global health problem with persisten demand on therapeutic development to inhibit cancer cells growth without harmful effects on healthy cells. Plant bioactive compounds are intensively studied as anticancer via several signalling pathway. Anticancer therapy via inhibition of tropomyosin kinase receptor-B (TrkB) signal was previously proposed as target therapy. The role of plant metabolites cyanidin and cyanidin-3-glucoside as TrkB inhibitor is has not been investigated. This study was aimed to identify physicochemical of cyanidin and cyanidin- 3-glucoside as well as determine it’s role towards TrkB receptor signalling pathway through in silico approach. Molecular docking was performed using Hex 8.0.0 software and visualizes using Discovery Studio Visualizer. The energy binding of TrkB with cyanidin and cyanidin-3-glucoside was -263,21 kcal/mol and 281,65 kcal/mol respectively. Complex of cyanidin-3-glucoside had hydrogen and hydrophobic bond more than TrkB-cyanidin complex. The hydrogen bond formed at Lys637, Arg558 and Gly 561 amino residues. Physicochemical analysis demonstrated that both ligand are potential as kinase enzyme inhibitor. Cyanidin-3-glucoside was predicted more potential as anticancer than cyanidin via TrkB receptor inhibition. Future studies are required to confirm current finding both in-vitro and in-vivo models.
Founder personality and harmful social exchanges within new venture teams
Authors: Brownell Katrina M. , Embry Elizabeth
Published: October 2024

Though scholars have explored how the personality composition of a new venture team relates to critical firm-level outcomes, research has not yet accounted for the impact of the lead founder, whose personality likely exerts a unique influence on team processes due to their elevated role. This is particularly critical in light of recent research highlighting the prevalence of the Dark Triad in entrepreneurship. We draw on social exchange theory to theorize and test how lead founder Dark Triad personality traits influence three intra-team processes: autonomy, innovation, and relationship conflict. In a time-lagged field study of nascent founders and their new venture teams (N = 102 intact teams), we found that lead founders who score high on Machiavellianism, narcissism, and psychopathy differentially effect these socially motivated team processes. By focusing on the influence that a single individual – the lead founder – can have within a new venture team, our findings offer balance to the literature, which predominantly focuses on team composition.
Provision of Digital Primary Health Care Services: Overview of Reviews
Authors: Fava Virgínia Maria Dalfior , Lapão Luís Velez
Published: October 2024

Background

Digital health is a growing field, and many digital interventions have been implemented on a large scale since the COVID-19 pandemic, mainly in primary health care (PHC). The development of digital health interventions and their application in PHC are encouraged by the World Health Organization. The increased number of published scientific papers on this topic has resulted in an overwhelming amount of information, but there is no overview of reviews to summarize this evidence.

Objective

This study aims to provide policy makers, health managers, and researchers with a summary of evidence on digital interventions used in PHC.

Methods

This overview of reviews searched the Web of Science and MEDLINE databases for systematic and scoping reviews on assessments of digital technologies implemented in PHC published from January 2007 to March 2023. Only reviews that addressed digital interventions whose targets were real patients or health care providers (HCPs) were included.

Results

A total of 236 records were identified from the search strategy, of which 42 (17.8%) full-text papers were selected for analysis, and 18 (7.6%) reviews met the eligibility criteria. In total, 61% (11/18) of the reviews focused their analysis on specific digital health interventions (client-to-provider telemedicine, provider-to-provider telemedicine, health worker decision support systems, systems for tracking patients’ health status, client participation and self-care platforms, and provision of education and training to health workers), and 39% (7/18) of the reviews focused on specific topics related to PHC (preventive care, chronic disease management, behavioral health disorders, the COVID-19 pandemic, multicomponent PHC interventions, and care coordination). Most studies in the included reviews agreed on barriers to implementation, such as software and apps developed without involving end users, the lack of training of HCPs and patients in digital technology use, and the lack of reimbursement and billing strategies for remote consultations. However, they showed several mixed results related to health service quality and patients’ clinical conditions and behavior changes.

Conclusions

Research in digital health applied to PHC is still concentrated in high-income countries, mainly in North America and Europe. The mixed results related to health service quality and patients’ clinical conditions or behavior changes may have been caused by deficiencies in the process of implementing digital interventions. It is necessary to examine the entire impact pathway and the causal relationship among implementation, health service quality, and clinical condition outcomes to support the spread of digital health in PHC settings.

Published: October 2024

Background

Sexual harassment (SH) and sexual assault (SA) are serious public health problems among US service members. Few SH and SA prevention interventions have been developed exclusively for the military. Code of Respect (X-CoRe) is an innovative web-based, multilevel, SA and SH intervention designed exclusively for the active-duty Air Force. The program’s goal is to increase Airmen’s knowledge and skills to build and maintain respectful relationships, ultimately reducing SH and SA and enhancing Airmen’s overall well-being and mission readiness.

Objective

This pilot study aimed to assess the short-term psychosocial impact (eg, knowledge, attitudes, and self-efficacy) of the web-based component of X-CoRe on a sample of junior enlisted and midlevel Airmen.

Methods

Airmen from a military installation located in the Northeastern United States were recruited to complete the 10 web-based modules in X-CoRe (9/15, 60% male; 7/15, 54% aged 30-35 years). Participants were given pretests and posttests to measure short-term psychosocial outcomes associated with SH and SA. Descriptive statistics and paired 2-tailed t tests were conducted to assess differences from preintervention to postintervention time points.

Results

After completing X-CoRe, participants had a significantly greater understanding of active consent (P=.04), confidence in their healthy relationship skills (P=.045), and confidence to intervene as bystanders (P=.01). Although not statistically significant (P>.05), mean scores in attitudes about SH, couple violence, and cyberbullying; perceptions of sexual misconduct as part of military life; and relationship skills self-efficacy with a romantic partner and friend also improved.

Conclusions

The findings from this study demonstrate X-CoRe’s effectiveness in improving critical determinants of SH and SA, making it a promising intervention for SH and SA prevention. More rigorous research is needed to determine X-CoRe’s impact on SH and SA victimization and the long-term impact on associated psychosocial determinants.
The mediating effect of depression on the relationship between jaw pain and frailty among Chinese older adults: a cohort study based on CLHLS from 2014 to 2018 (Preprint)
Authors: Zhang Jiajun , Xu Jing , Yu Yue , Yu Yaokun , Su Mingzhu , Yue Hanlin , Liu Li , Yuan Ding
Published: October 2024

BACKGROUND

Although there has been considerable research on the association between oral health, depression, and frailty, a majority of studies have been cross-sectional, and no research has investigated the relationship between all three.

OBJECTIVE

The purpose of this cohort study was to explore the association between jaw pain and frailty, and the mediating effect of depressive symptoms in Chinese older adults

METHODS

Based on the Chinese Longitudinal Healthy Longevity Survey (CLHLS) from 2014 to 2018, 2134 Chinese people aged 60 and over were included in this study. Jaw pain, depressive symptoms, frailty, and other variables were assessed by a self-reported questionnaire. Logistic regressions were conducted to test the association between jaw pain, depression, and frailty. Path analysis was applied to examine the mediating role of depression.

RESULTS

The prevalence of frailty was 16.73% in 2018. Jaw pain and depressive symptoms were related to frailty in the elderly population of China. Path analysis revealed that the relationship between jaw pain and frailty was partially mediated by depression. After adding the covariates, the mediation effect size of depression on the association between jaw pain and frailty was 21.32%.

CONCLUSIONS

In older adults, jaw pain poses a risk for frailty, and depression mediates between the two. To slow the progression of frailty, attention, and targeted measures are needed for oral health and mental health in older adults.
Demonstration of Grover’s algorithm for retrieving secret keys in a basic SPN block cipher
Authors: Vu Minh Thang , Nguyen Van Nghi , Le Quoc Dat , Do Quang Trung
Published: October 2024

In this study, we present in detail the application of Grover's quantum algorithm to the searching problem of the secret key of a simple SPN (Substitution–permutation network) block cipher called Yo-yo. The main goal of the paper is to clarify the construction of the quantum circuit and the operation phases of Grover's algorithm to find the secret key with the condition of knowing at least 1 pair of plaintext-ciphertext. To achieve this goal, we consider 2 cases: the case where there is a unique key that satisfies and the case where there are 2 keys that satisfy at the same time. As a result, our implementation technique, implemented in the Qiskit programming language, requires only 17 qubits to find the key of the Yo-yo block cipher correctly. This technique can be effectively applied on IBM quantum computers for large-scale SPN block ciphers, such as AES and GOST R.34.10.2015, which are widely used today.

Published: October 2024

The advancement of information technology has influenced and accelerated the growth of many economic fields and industries, including e-commerce. This is one area of information technology that has rapidly developed and gained widespread popularity due to the significant benefits it offers to the community. Today, the need for online shopping is increasing because of its convenience and timesaving, especially for busy people. Historical session data plays an important role in helping sales systems recommend orders to customers that suit their personal preferences. This study proposes models for recommending products on online sales systems based on transaction sessions using memory-based collaborative filtering methods, including user-based and item-based, and model-based collaborative filtering methods including SVD and KNN. The experimental results show that the SVD model has a better rating prediction performance than other techniques. Therefore, it is probably proposed for product recommendations on online sales systems.
Assessing wind energy exploitation potential in several regions of Viet Nam using Kernel density estimation model
Authors: Chau Tin Trung , Nguyen Tuan Ngoc , Do Ton Duc
Published: October 2024

This article analyzes and assesses the potential for wind energy exploitation in six regions of Vietnam. The wind speed data are used to construct wind speed probability distributions (WSPDs) based on kernel density estimation (KDE). The KDE distribution, with six bandwidth selection methods, is implemented to generate probability density functions (PDFs) for each region's data to describe wind speed characteristics. The statistical tests Cramér-Von Mises (CvM), Anderson-Darling (A-D), and Kolmogorov-Smirnov (K-S) are applied to evaluate the PDFs' goodness-of-fit performance. The analysis results present the KDE distribution using the least-squares cross-validation (LSCV), and the Scott bandwidth selection method has outstanding fitting performance. Based on these PDF distributions, the wind turbine (WT) power curve is used to estimate and predict the amount of electricity that can be produced. This study also proposes a reliable method for wind power output planning based on wind speed that can be universally applied.

Halal products uphold the principles of halal throughout the entire supply chain, making managing the halal supply chain (HSC) crucial, especially for Muslim communities. Despite the importance of this topic, existing literature on halal supply chains remains limited, with most studies concentrating on the food industry. Notably, there is a significant research gap regarding the development of HSC research in Indonesia, the country with the largest Muslim population. This study aims to address this gap by conducting a comparative analysis of HSC research in Indonesia and globally. Utilizing Scopus as the data source, 355 studies on halal supply chains published between 2008 and 2024 were analyzed. A comparative study was then conducted to evaluate the development of HSC research in Indonesia based on various categories, including the number of publications, subject areas, authors, keywords, citations, paper quartiles, institutional affiliations, research objects, methods, and themes. The findings reveal that while Indonesia has made significant progress in HSC research, the research is still tiny compared to its Muslim population. These results highlight the need for further investment and focus on HSC research in Indonesia to match its global potential.

Besar atau kecilnya performa dalam suatu mesin salah satunya dapat dipengaruhi oleh sistem pengapiannya. CDI (Capacitor Discharge Ignition) adalah Sebuah komponen dalam sistem pengapian motor, yang bertugas menghasilkan percikan api pada busi dengan waktu yang tepat untuk membakar campuran bahan bakar dan udara di dalam silinder mesin. Dalam system kerjanya CDI memiliki 2 type CDI DC dan CDI AC. CDI yang rusak dapat mempengaruhi kinerja motor dan keamanan pengendara. Seperti yang dialami pada customer kendaraan motor Beat 110CC dengan CDI DC pada bengkel AGC, dengan keluhan kendaraan motornya susah menyala dan sering mogok saat dikendarai. Penelitian ini bertujuan untuk menganalisis penyebab dari kerusakan CDI pada mesin motor Beat 110CC. Pada penelitian tersebut menggunakan metode eksperimental yang melibatkan pengujian langsung terhadap CDI yang rusak tersebut. Hasil dari metode eksperimental bahwa penyebab CDI rusak pada motor Beat 110CC disebabkan Over Voltage di Kiprok pada arus pengisian ke baterai. Baterai yang menerima tegangan berlebih secara otomatis mengirimkan tegangan yang berlebih pada CDI. Normal nya output dari kiprok 12V-14V ketika sudah melebihi angka tersebut maka dapat menyebabkan tegangan aki tidak stabil dan menyebabkan CDI rusak. Berdasarkan analisis penelitian dan pembahasan, dapat menyimpulkan hasil penelitian. Bahwa untuk mengatasi rusaknya CDI pada kasus tersebut dengan mengganti kiprok agar arus yang di input oleh baterai tetap stabil. Ketika kendraan sudah mengalami masalah segera bawa ke bengkel agar dapat terhindar dari kerusakan yang serius dan memastikan kinerja motor tetap dalam kondisi optimal
