Knowledge Graph Completion Model based on Hyperbolic Hierarchical Attention Network
Authors: Luo Jiaohuang , Song Changlong
Published: November 2023

In Knowledge Graph Completion (KGC), missing knowledge triples are inferred based on known facts in the knowledge base. In recent years, several representation learning models for knowledge reasoning have achieved promising link prediction results, especially those based on graph attention networks and their derivatives. Such models typically leverage local neighborhood information for each node to learn representation vectors of target entities. However, existing knowledge representation models solely focus on entity embeddings and employ straightforward linear transformations to update relationships. Hence, they are unable to effectively explore structured information with different semantics at the entity and relationship levels. To address these issues, a novel Hyper-bolic Hierarchical Attention Network model for Knowledge Graph Completion (HHAN-KGC), is proposed, incorporating the inference capabilities of hyperbolic algorithms for structured data and the learning capabilities of hierarchical attention networks for entities and relationships, jointly extracting feature vectors for entity and relationship layers. The hyperbolic hierarchical attention network consists of a dual-layer attention mechanism and a relationship semantics mechanism , designed to deeply explore hierarchical feature information embedded in local structures. Thus, HHAN-KGC can establish close associations among triples at different semantic levels, ensuring that the learned knowledge representations possess a certain degree of fidelity and effectively aggregate structured information from entity and relationship layers. Experimental results on multiple knowledge graph datasets demonstrate that HHAN-KGC outperforms the current state-of-the-art methods for knowledge graph link prediction.
Management of incessant Ventricular Arrhythmias in a Patient with left ventricular assist device: a case report
Authors: Chen Chen , Du Juan , Wang Xianqiang , Zou Liang
Published: November 2023

Background
The implementation of left ventricular assist devices (LVADs) as a bridge to transplantation or as destination therapy in end-stage heart failure patients is frequently complicated by the emergence of ventricular arrhythmias (VAs). These arrhythmias have been implicated in precipitating deleterious clinical outcomes, increased mortality rates and augmented healthcare expenditures. The strategic management of VAs in the context of LVAD support is a critical area of ongoing research.
Case Presentation:
We present a challenging case of a 49-year-old male with a history of dilated cardiomyopathy who received an LVAD. Post-implantation, the patient suffered from intractable VAs, leading to multiple rehospitalizations and hemodynamic deterioration. Despite exhaustive medical management and electrical cardioversion attempts, the patient's VAs persisted, ultimately necessitating prioritization for cardiac transplantation.
Discussion
This case highlights the challenges in managing VAs in LVAD patients and the importance of multidisciplinary collaboration. While pharmacological intervention is the initial strategy, catheter ablation may be considered in selected cases when medication is insufficient. In instances of intractable VAs, expeditious listing for heart transplantation as a high-priority candidate is advisable when feasible.
Sitting foot: Posture dependent changes of volume, edema and perfusion of the foot. A prospective interventional study with 27 volunteers
Authors: Freund Wolfgang , Wikstroem Peter , Wunderlich Arthur P , Schuetz Uwe , Beer Meinrad
Published: November 2023

Background
Sitting is known to be bad for your cardiovascular health. We furthermore hypothesized that sitting posture will reduce perfusion of the foot and increase edema, possibly predisposing to disease like osteochondritis.
Methods
We included 27 healthy volunteers and performed MRI measurements including arterial spin labelling (ASL) and intravoxel incoherent motion (IVIM) perfusion as well as short tau inversion recovery (STIR) edema measurement and 3D volumetry. After randomization, the elevation of one foot during the day was used as an intervention.
Results
Intra- and interrater variability was 1-6%.
ASL perfusion measurement was hindered by artifacts. IVIM perfusion showed no significant changes during supine measurements.
Volumetry could demonstrate a highly significant (p=0.00005) volume increase, while the intervention led to a significant (p=0.0076) volume decrease during the day. However, the water content in STIR remained unchanged and the normalized (quotient bone/muscle) edema was reduced on the control side (p=0.006) and increased on the intervention side (p=0.01).
Conclusions
Sitting all day leads to swelling of the healthy foot. Compensation in healthy subjects seems to prevent lasting perfusion changes or edema evolution in the bone despite an increase of muscle signal and volume increase. Thus, the etiology of osteochondritis needs further studies.

Authors: Liao Changpin , Cen Jian , Li Xiaolei , Li Zhonghua , NORDIN RUSLI BIN , Li Tingyang , Ye Jing , Huang Lide , Wei Wei , Wei Xianfu , Yang Haiyan , Chen Wu , Han Jianglong
Published: November 2023

Objective
To explore the positive rate of pathological results and safety of enhanced CT, DTI, and 1H-MRS assisted robot-guided brain glioma biopsy.
Methods
Eighteen patients with imaging-diagnosed brain gliomas who underwent robot-guided brain glioma biopsy in the Department of Neurosurgery of Baise People's Hospital from January 2021 to October 2022 were selected as the study subjects. All patients underwent preoperative examinations such as enhanced CT, DTI, and 1H-MRS. The neurosurgical robot Reme-Studio automatically fused the image pictures, using the principles of enhanced CT vascular imaging points, DTI reconstructed conduction bundle three-dimensional stereograms, and 1H-MRS indicating the tumor cells, to perform robot-guided brain glioma biopsy. The specimens were sent to the pathology department for routine pathological results, and the positive rate of specimens and postoperative complications were recorded.
Results
All 18 patients obtained clear pathological grades, and no intracranial bleeding requiring emergency surgery or new-onset neurological dysfunction occurred after surgery.
Conclusion
Enhanced CT, DTI, and 1H-MRS assisted robot-guided brain glioma biopsy can accurately locate and puncture the metabolic hotspots of the edema zone, marginal zone, and tumor body CHo/NAA maximum value, avoiding important blood vessels and conduction bundles. It is not only an important method to improve the positive rate of pathological results but also safe and reliable.
Absorption Spectra of p-Nitroaniline Derivatives: Charge Transfer Effects and the Role of Substituents
Authors: Máximo-Canadas Matheus , Borges Itamar
Published: November 2023

Context
Push-pull compounds are model systems and have numerous applications. By changing their substituents, properties are modified and new molecules for different applications can be designed. The work investigates the gas phase electronic absorption spectra of fifteen derivatives of p–nitroaniline (pNA) using theoretical methods. This molecule has applications in pharmaceuticals, azo dyes, corrosion inhibitors, and optoelectronics. Both electron-donor and electron-withdrawing groups were investigated. Overall, electron-donors redshift the absorption spectrum and reduce the HOMO-LUMO energy gap. Conversely, electron-withdrawing groups blueshift the spectrum and increase the energy gap. A comprehensive charge transfer (CT) analysis of the main transition of all systems was also carried out. We found that donors slightly enhance the CT character of the unsubstituted pNA, whereas acceptors decrease it, leading to increased local excitations within the aromatic ring. The overall CT variation is not large, except for pNA–SO2H, which considerably decreases the total CT value. It was found that the strong electron donors pNA–OH, pNA–OCH3, and pNA–NH2, which have small HOMO-LUMO energy gaps, have potential for optoelectronic applications.
Methods
We investigated theoretically employing the second-order algebraic diagrammatic construction (ADC(2)) ab initio wave function the gas phase electronic absorption spectra of fifteen derivatives of p–nitroaniline (pNA). The substituents considered in this investigation included both electron-donor (C6H5, CCH, CH3, NH2, OCH3, and OH,) and electron-withdrawing (Br, CCl3, CF3, Cl, CN, COOH, F, NO2, and SO2H) substituents. Employing machine-learning-derived Hammett's constants σm, σm0, σR, and σI, correlations between substituents and electronic properties were obtained.
Decomposition of the changes in household disposable income distribution in China
Authors: Gong Chen , Sologon Denisa , Nimeh Zina , O'Donoghue Cathal
Published: November 2023

Studies have shown that the previously growing inequality in China has stabilized and even declined since 2008 (Kanbur et al., 2021), nevertheless, the drivers of the latest transformation in income inequality remain to be unraveled. We address this research gap by examining the changes in the distribution of household disposable income and its drivers in China from 2010 to 2016. We apply the distributional decomposition method proposed by Bourguignon et al. (2008) and Sologon et al. (2021), and quantify the contribution of all factors into four general dimensions, (1) demographic composition, (2) labor market structure, (3) price and return, and (4) governmental transfers.
This study considers not only the individual labor income as with existing literature, but also models other family incomes and social transfers to reflect the real economic conditions more accurately. The decomposition results show that all four factors contribute positively to the decline in income inequality during the period studied. The changes in urban labor market structure, specifically the general forms of employment, occupational and industrial structure, have been contributing as inequality augmenting factors.

Reinforcement learning in biological systems for adaptive regulation
Authors: Yamaguchi Tomoyuki
Published: November 2023

The adaptive control of complex biological systems remains unclear despite extensive research on their regulatory networks. We recently reported that epigenetic regulation of gene expression may be a learning process, in which amplification-and-decay cycles optimize expression patterns while basically maintaining current patterns. Here, we show that various biological processes, such as intestinal immunity, population dynamics, chemotaxis, and self-organization, are also characterized as reinforcement learning (RL) processes. An appropriate population balance is established autonomously through symmetric competitive amplification and decay, which is a biologically plausible RL process. Monte Carlo simulations of predator-prey numbers show that population dynamics based on this RL process enable the sustainability of predators and reproduce fluctuations with a phase delay when humans hunt prey more preferentially than predators. Another example is a random walk controlling step-length (s-rw), which allows the agent to approach the target position with a Levy walk trajectory. In addition, shortcut paths in a maze are autonomously generated by s-rw using a moving-direction policy or bias, which is optimized through another RL on a longer timescale. Furthermore, by applying s-rw to reaction-diffusion theory, Turing patterns can be self-organized. The RL process, expressed by a common mathematical equation, enables the adaptability of biological systems.
LSDNet: A Lightweight Ship Detection Network with Improved YOLOv7
Authors: Lang Cui , Yu Xiaoyan , Rong Xianwei
Published: November 2023

Accurate ship detection is critical for maritime transportation security. Current deep learning-based object detection algorithms have made marked progress in detection accuracy. However, these models are too heavy to be applied in mobile or embedded devices with limited resources. Thus, this paper proposes a lightweight convolutional neural network shortened as LSDNet for mobile ship detection. In the proposed model, we introduce Partial Convolution (PConv) into YOLOv7-tiny to reduce its parameter and computational complexity. Meanwhile, GhostConv is introduced to further achieve lightweight structure and improve detection performance. In addition, we have replaced Mosaic-4 data augmentation with Mosaic-9 to enhance the robustness of the model. We compared the proposed LSDNet with other approaches on a publicly available ship dataset, SeaShips7000. The experimental results show that LSDNet achieves higher accuracy than other models with less computational cost and parameters. The test results also suggest that the proposed model can meet the requirements of real-time applications.

Confirmatory factor analysis indicates a good model fit of the three correlated factors (Comparative fit index (CFI) = 0.92 with root mean square error of approximation (RMSEA) = 0.059[0.063–0.066] and standardize root mean residual SRMR = 0.045). The internal consistency of overall DASS-21 and each sub scale were in acceptable range (0.82, 0.77and 0.77) respectively.
Conclusion
Amharic version of DASS-21 was found to be a valid and reliable instrument to measure the mental problem especially, Depression, Anxiety and Stress among university students.
Validation of Microsatellite Markers for Sex Determination in Date Palm (Phoenix dactylifera) cv. Madjoole
Authors: Salameh Aziz , Hamdan Yamen , Aslan Khaled
Published: November 2023

The date palm (Phoenix dactylifera) is a dioecious plant, and its sexual characteristics remain indiscernible until it reaches the reproductive stage, typically between 4 to 5 years of age. The cultivar C. madjoole is widely grown in Palestine and neighboring regions. Early identification of male and female seedlings could significantly benefit date palm cultivation and breeding efforts. This study aimed to confirm the effectiveness of microsatellite markers in distinguishing between male and female date palms within the cv. Madjoole variety. Out of eight microsatellite primers used, four markers were able to determine the sex of the date palm tree. mPdCIR010 produced a male specific band (325pb) while mPdCIR093 produced a female specific band (335 pb); on the other side, mPdCIR015 and mPdCIR078 produced unique female bands (160 and 128 pb), respectively. A total of 15 loci were identified, averaging 2.1 loci per primer. SSR markers were able to provide a reliable technique for sex determination in date palm (cv. Madjoole) at an early stage. The utilization of SSR markers will not only advance but also facilitate the establishment of commercial date palm cultivation through seed propagation in Palestine and the surrounding region. Consequently, the available date palm genetic resources could be expanded, leading to enhanced national breeding programs. The ability to use mPdCIR093 as a female specific marker is approved for cv. Madjoole but needs to be validated with other date palm cultivars.
Evolution of radiation-induced temporal lobe injury after intensity-modulated radiation therapy in nasopharyngeal carcinoma: a large cohort retrospective study
Authors: Hou Jing , He Yun , Li Handong , Ai Zhaodong , Lu Qiang , Zeng Biao , Xie Chuanmiao , Yu Xiaoping
Published: November 2023

Background
Previous studies have demonstrated conflicting findings regarding the initial MRI patterns of radiotherapy-induced temporal lobe injury (RTLI) and the evolution of different RTLI patterns. The aim of this study was to evaluate the initial MRI pattern and evolution of RTLI in patients with nasopharyngeal carcinoma (NPC) by means of a large cohort study.
Methods
Data of patients with RTLI were retrospectively collected from two hospitals between January 2011 and December 2021. The injured lobes were categorized into three patterns based on initial MRI patterns: isolated white matter lesions (WMLs), isolated contrast-enhanced lesions (CELs), and combined WMLs and CELs. The latency period, MRI appearances, and temporal changes in WMLs and CELs were evaluated.
Results
A total of 913 RTLI patients with 1092 injured lobes were included in this study. The numbers of isolated WMLs, isolated CELs, and combined WMLs and CELs identified at the first MRI detection were 7(0.6%), 172(15.8%), and 913(83.6%), respectively. The evolution of bilateral RTLI was different in the same patient, and that of unilateral RTLI combined with WMLs and CELs also may occur asynchronously. The time intervals from the initial MRI detection of isolated WMLs, isolated CELs, combined WMLs and CELs to the last negative MRI scan were 8.6, 8.9 and 11.0 months, respectively. A significant difference was observed in the time intervals between the three patterns (H = 14.287, P = 0.001). And the time interval was identified as an independent factor influencing the initial MRI pattern of RTLI after Poisson regression (P = 0.002).
Conclusion
Both WMLs and CELs could be the initial and only MRI abnormalities in patients with RTLI. This study is of great significance in accurately diagnosing RTLI early and providing timely treatment options. Additionally, it provides clinical evidence for guidelines on NPC, emphasizing the importance of regular follow-up of NPC patients.

Published: November 2023

Background Laparoscopic cholecystectomy (LC) is widely accepted as the definitive therapeutic approach for MABP, primarily aiming to reduce recurrent biliary complications. However, the optimal timing of LC remains a matter of debate. The aim of this study was to evaluate the efficacy and safety of early laparoscopic cholecystectomy (ELC) versus delayed laparoscopic cholecystectomy (DLC) in patients with mild acute biliary pancreatitis (MABP).
Methods The PubMed, Embase, Scopus, and CENTRAL databases were systematically searched for randomized clinical trials (RCTs) comparing ELC with DLC in patients with MABP from inception to August 1, 2023. The primary outcome was recurrent biliary events. Secondary outcomes included postoperative complications, readmissions, and length of stay (LOS). The pooled risk ratio (RR) or standardized mean difference (SMD) of data was calculated using the random-effects model.
Results Fifteen RCTs with 1616 patients enrolled between 2010 and 2022 were included. High-certainty evidence from nine RCTs demonstrated a significantly lower risk of recurrent biliary events in patients who underwent ELC during the waiting time compared to DLC (RR=0.128[0.063, 0.262], P<0.001). For secondary outcomes, ELC in patients with MABP was associated with a significantly lower readmission rate (RR=0.382[0.182, 0.801], P=0.011) and shorter LOS (SMD=-2.026[-2.854, -1.198], P<0.001) than DLC. Subgroup analysis indicated that patients with ELC had a significantly lower rate of postoperative complications in accordance with the Atlanta criteria, MABP, and >4 weeks subgroup.
Conclusions ELC emerges as a generally safe and effective strategy in reducing recurrent biliary events, postoperative complications, readmission, and length of stay for patients with MABP.

Kleingewässer der Colbitz-Letzlinger Heide unter besonderer Berücksichtigung der Vegetation
Authors: Werstat Claus
Published: November 2023

Die Colbitz-Letzlinger Heide liegt in Sachsen-Anhalt nordwestlich von Magdeburg. Sie nimmt eine Fläche von über 700 km² ein, darin eingeschlossen liegt der Truppenübungsplatz „Altmark“ mit 220 km². Das Gebiet gehört naturräumlich zu den Altmarkheiden und geologisch zum Altpleistozän. Seit Beginn der militärischen Nutzung 1935 sind bis heute große Teile des Heidegebietes nur begrenzt zugänglich. Zu den Kleingewässern liegen daher kaum Angaben vor. Die 58 untersuchten Kleingewässer erreichen durchschnittlich eine Gesamtgröße (inklusive Uferbereiche) von nur 2700 m². Sie sind sehr flach und haben in der Regel weder Zunoch Abfluss. Sie werden fast ausschließlich vom Niederschlag gespeist. Hinsichtlich ihrer sehr unterschiedlichen Wasserführung konnten in Anlehnung an KALETTKA (1996) vier Typen von Kleingewässern unterschieden werden. Neben der Lage, Größe und Wasserführung der Gewässer wurde vor allem deren Vegetation untersucht. Sie gibt Auskunft über die Pflanzengesellschaften unter den gegebenen Standortverhältnissen der Colbitz-Letzlinger Heide. Die Variabilität der Standortfaktoren, insbesondere die räumliche und zeitliche Dynamik des Wassers erschwert das Erkennen und Erfassen der Pflanzengesellschaften. Die klassischen Methoden der Pflanzensoziologie bringen daher vielfach nicht den gewünschten Erfolg. Der erste Teil der Untersuchungen folgt daher HAMEL (1988) und MIERWALD (1993) und untersucht die Vegetation nach den auftretenden Vegetationskomplexen. Diese setzen sich aus mehreren pflanzensoziologisch abgrenzbaren Beständen zusammen, die das Nebeneinander verschiedener ökologischer Standortbedingungen auf kleinem Raum widerspiegeln. Im zweiten Teil wird zusätzlich eine klassische vegetationskundliche Analyse vorgelegt. Beide Methoden ergänzen sich in ihrer Aussage. Der Anhang bietet eine Übersicht über die Kleingewässer.

Is Natural Solar Photolysis Effective for the Removal of Antibiotics and Pathogens from Waste Stabilization Pond?
Authors: Lima Karla , de Jesus Jany , Bronzel Junior João , Nogueira Raquel
Published: November 2023

This study aimed to investigate the occurrence of photolysis of two relevant antibiotics, sulfamethoxazole and trimethoprim, when present in a Waste Stabilization Pond and its disinfection under tropical irradiance. The influence of pH and matrix components, and the generation of photoproducts during solar exposure were evaluated. The pH-dependent speciation of antibiotics had a greater influence on the photolysis of antibiotics than the water matrix, with higher photodegradation at pH 4.1 than at pH 7.2. Trimethoprim was more susceptible to indirect photolysis, indicated by the steeper influence of the photosensitizers nitrate and humic acid compared to sulfamethoxazole. The photoproducts generated were persistent to photolysis and remained present in the samples up to 70 h irradiation. Wastewater disinfection was achieved after 70 h of solar exposure. Nonetheless, the exposure time required to remove at least 50% of sulfamethoxazole was on average 29 h and of trimethoprim 83 h, at the natural pH of the matrix (pH 7.2). Given that the residence time in Waste Stabilization Pond is 41 h, which corresponds to a maximum of 26 h solar irradiation, the exposure time in Waste Stabilization Pond is not sufficient to completely photodegrade antibiotics or disinfect the effluent, demanding further treatment.
Experimental Design Modelling and Optimization of the Intercalation of Levofloxacin and Salicylic Acid into the Structure of ZnAl-LDH by Response Surface Method: in vitro Study of Release Kinetics, Antibacterial and Anti- Inflammatory Activities
Authors: Vy Ngo , Khanh Dang , Khoa Le , Phat Nguyen , Thang Nguyen , Trung Le , Nhu Nguyen , Phuong Doan , Phuong Nguyen
Published: November 2023

In recent years, solid-state engineering has emerged as a promising method for improving the stability and potency of antibiotics and anti-inflammatory drugs. This study focuses on the design and optimization of the intercalation of levofloxacin (an antibiotic drug) and salicylic acid (an anti-inflammatory drug) into zinc-aluminium-layered double hydroxide galleries using response surface method. Release studies revealed that a burst release phenomenon was observed at the beginning of the release assay, and the pH value (in the range of 5.8-7.4) had very little influence on the levofloxacin and salicylic acid release efficiency. This indicates that zinc-aluminium-layered double hydroxide could be an effective inorganic carrier for levofloxacin and salicylic acid over a wide range of pH values. Four kinetic models were used to study the release kinetics and the drug release mechanism was also discussed. In addition, the intercalation of levofloxacin and salicylic acid into zinc-aluminium-layered double hydroxide exhibited enhanced antibacterial activity against Gram-positive Bacillus subtilis. The cell viability assay revealed non-toxic behavior of levofloxacin and salicylic acid intercalated into zinc-aluminium-layered double hydroxide against the monocyte/macrophage-like cell line.
Prevention of School Bullying Among Adolescents of Individual Educational Organizations for Students with Disabilities: a Model of Antibulling Competence and Evaluation of its Efficiency
Authors: Molchanova L. N. , Fomina A. V.
Published: November 2023

The scale of bullying among teenagers is becoming global. Students with intellectual disabilities are subjected to emotional, physical and mental pressure in educational institutions for children with disabilities, which ensures the need to develop and implement an anti-bullying competence model of prevention. The study involved 26 teenagers from Kursk Boarding School No. 3 at the age of 14-16. Data collection was carried out through observation and conversation using standardized methods for diagnosing the socio-psychological determinants of bullying. The implementation of the ascertaining and control stages of the formative experiment included diagnosing the risk of bullying, sociometric status and the prevalence of bullying in the educational environment, as well as evaluating the results using statistical methods of mathematical analysis (“Statistica 11.0”). Developed in accordance with the competency-based model of preventing school bullying among adolescents, the program is aimed at reducing the level of bullying through the optimization of their intragroup relationships. Evaluation of the results of its implementation testified to changes in the prevalence of bullying and a change in the status-role structure of the experimental group in comparison with the control group and with the results of primary diagnostics, and hence its effectiveness. The class team showed a high degree of cohesion, discipline and organization. Measures were successfully carried out to raise awareness of all participants in the educational process, to create a favorable socio-psychological climate in the school community for the comprehensive development of the personality of adolescents with intellectual disabilities. Adolescents demonstrated high activity not only during school hours, but also outside school hours.

Authors: Astuti Dyah Dwi , Wanda Dessie
Published: November 2023

Background: The agenda for strengthening the global health architecture is to improve quality of life for premature infants. Premature births increase the morbidity and mortality of newborns, necessitating innovation in primary health care.

Objectives: This study was conducted to examine innovation programs with a continuity of care approach in primary health care for premature infants in an effort to strengthen the global health architecture.

Methods: A literature review method was used to analyze articles obtained using databases such as Science Direct and Google Scholar. The researcher used the key words “continuity of care” and “premature infants”. The inclusion criteria were full-text journal articles published from January 2020-December 2022 in English-language journals.

Results: This study obtained ten articles that correspond to the continuity of care approach for premature infants. The articles included four qualitative studies, three quantitative studies, one mixed-method study, one literature review, and one systematic review. There are three themes related to the continuity of care for premature infants, including (1) Primary healthcare with information continuity, relationships continuity, and management continuity; (2) Continuity of care in the antenatal, natal, and postnatal periods; (3) The continuity of care on premature infant approach improves the outcome of premature infant care, the ability of parents, and health service quality.

Conclusions: A continuity of care approach can increase the achievement of adequacy, equity, efficiency, and effectiveness in primary health care for premature infants. Joint synergy between the community, health services, and health policymakers is essential in efforts to strengthen the quality of life for premature infants.

The main objective of the present study was to assess the status and determining factors to develop student self-regulated behavior in learning among fourth generation universities in Ethiopia. To achieve this objective, both quantitative and qualitative data were collected from primary and secondary source of data. The study employed random and purposive sampling techniques to select 270 instructors, 4 department heads and 6 well-experienced teachers. Data from the quantitative survey were analyzed using mean, standard deviation, t-test, analysis of variance and multiple regressions. Qualitative data was analyzed through thematic narration. The study found that the mean score of teacher’s practice of self-regulated behavior in learning was 2.72 and standard deviation 4.379. The independent samples t-test and One-way ANOVA indicated that, there was statistically significant mean difference in gender and educational statues of teachers’ in practice of self-regulated strategies. Women and teachers who had higher educational status performed better than other instructors. Multiple regression analysis indicated teachers’ negative attitude toward their profession and lack of commitment was significant factor for low development of self-regulated behavior in learning in fourth generation Universities in Ethiopia. However, pedagogical knowledge, teaching experience, age and educational was non- significant at P<0.05 level of significance.

Bayesian Neural Networks for Enhanced Predictive Performance in Regression Problems
Authors: Patil Manaswi
Published: November 2023

Abstract: Bayesian statistics has a lot of influence on neural networks and deep learning for artificial intelligence (AI). The inference and learning of Bayesian statistics is based on prior, likelihood and posterior. The prior is the current belief of data field and the posterior is the updated belief after learning from observed data. By repeated learning using prior and posterior distributions, Bayesian statistics provides advanced data learning for AI. In this paper, we compare the previous Bayesian inference and learning methods for AI and propose a model based on Bayesian inference and learning for neural networks and deep learning

This study identifies the limitations of conventional teaching methods, such as textbooks and lectures, in delivering Pancasila education to fourth-grade elementary school students. These methods could be more engaging and effective in improving students' learning outcomes and understanding of the subject matter. This research aims to develop an interactive and engaging E-module to enhance students' learning outcomes and understanding of Pancasila values. This research employed a developmental approach known as Randomized Controlled Trial (RCT) using the 4D model (Define, Design, Develop, and Disseminate). The validity of the E-module is assessed through expert validation involving media and subject matter experts. The evaluation results demonstrate the high validity of the developed Pancasila Education E-module, created using Canva for Education and assisted by Flip PDF Professional. The Aiken V index indicates a score of 0.87%, with all evaluation aspects falling within the 0.8 ≤ V ≤ 1 range. Moreover, the practicality of the E-module is confirmed, with a practicality level of 84.3%. The E-module was tested by teachers and fourth-grade students, with the involvement of the entire class. The test results show an improvement in students' learning outcomes, with an overall pretest percentage of 95.5% and a post-test percentage of 92.5%. Hence, the Pancasila Education E-module effectively enhances students' learning outcomes and understanding of Pancasila values. This research enriches the teaching methods of Pancasila education in fourth-grade elementary schools.

Published: November 2023

En la agroindustria se genera una considerable cantidad de residuos, los cuales pueden ser tratados usando diversas tecnologías termoquímicas como la carbonización hidrotermal. El rendimiento y contenido de carbono de biomasas son dos de las características más comunes que se estudian dentro del proceso generado en estas tecnologías tecnoquímicas, y usualmente se aplican análisis químicos y técnicas estadísticas, tales como pruebas t-student, análisis de varianza o modelos de superficies de respuestas para optimizar estas respuestas o estimar el efecto que ciertos factores puedan tener sobre estas. A diferencia de las investigaciones abordadas en esta área de la química, este estudio tuvo como propósito introducir diferentes técnicas alternativas de la estadística para la modelación de este tipo de datos con el fin de proponer diferentes estrategias de análisis que permitan ampliar el conocimiento de los fenómenos estudiados en esta área. Para ello, se presentó la modelación estadística de dos bases de datos provenientes de bagazo de manzana y de arándanos que contienen un total de cuatro factores (tiempo, humedad, potencia, temperatura) y dos respuestas a analizar por separado (contenido de carbono y rendimiento del proceso). En este estudio se observa que el tiempo, la temperatura y la humedad tienen un efecto conjunto sobre el rendimiento del proceso y el contenido de carbono de la biomasa proveniente de la manzana. Se concluye que, técnicas como modelos lineales generalizados con respuesta beta y los modelos aditivos generalizados de posición, escala y forma, proporcionan un mayor conocimiento del fenómeno de interés y la capacidad de estimar el efecto de los factores estudiados sobre respuestas que naturalmente no poseen un comportamiento distribucional como el modelo normal.
Examining the design parameters for balcony in muslim sudanese apartments with a view to enhance social interaction and visual privacy
Authors: Yousif Maysa , Abdul Aziz Aniza
Published: November 2023

The balcony is considered an important element that makes valuable contributions to residential buildings at various levels, such as its function, use, design, and values. Balconies should be designed to improve the residential unit’s internal environment and be used for significant functions not only as a service area but also as a place for social interaction. Therefore, this study aims to analyse the balcony design variables that improve the degree of activity, privacy, interaction, and comfort for apartment unit residents, especially in Khartoum, where most of the population is Muslim. In order to evaluate the different variables and responses from residents, a mixed-method approach is used, combining questionnaire surveys and case study approaches. The findings revealed the significance of balcony space in Sudanese culture; also, respondents strongly support the idea that balconies might replace the function of traditional house yards if they evolve with a particular level of privacy and acceptable size. Hence, this paper provides design guidelines for balconies in apartment blocks that are suitable not only for the Sudanese but also the Muslims in general to preserve the good social culture.
