Published: July 2024

The article deals with the problem of human resources in Ukraine in connection with the migration of a significant part of the working population abroad. It is proved that an enterprise that can reprofile its employees will always have human capital since the ability to teach and retrain people is becoming key in the issue of labor shortage. The article examines the relevance of the issue of personnel outflow abroad on the example of the activities of the Husiatyn furniture factory "Elegant". In order to overcome the staff shortage, the author proposes long-term and short-term models of staffing. The conditions of cooperation with the Husiatyn Vocational College of Ternopil National Technical University named after Ivan Puluj on the conclusion of an agreement on joint training of personnel in two specialties "Carpenter" and "Seamstress" were studied. It was concluded that to immediately overcome the shortage of staff in blue-collar occupations, the management of the “Elegant” furniture factory should resort to the development and application of a short-term staffing strategy through a short-term training model. First of all, sewing was chosen to implement the plan. The budget of the short-term vocational training model is calculated. It has been substantiated that the implementation of this project on time will increase the efficiency of the sewing unit by 20% due to the process of staffing with sewing personnel. This will lead to an increase in the production of furniture products and an increase in sales. The link between long-term and short-term staffing models was established. Thus, for the public confidence of the employee, after a short-term vocational training at the furniture factory "Elegant", the management of the enterprise will offer the best personnel to enter the Husiatyn Professional College in this specialty at the expense of the factory. The condition for financing training at the educational institution will be the employee's obligation to work at the furniture factory for a period equal to the training period. It is established that it is advisable for Ukrainian manufacturers to develop a competitive economic strategy aimed at increasing labor potential. Proposals from business entities should be attractive and convincing to workers and act as a guarantee of staffing.

Published: July 2024

Background: Penile fracture is a surgical emergency and most often it can be diagnosed clinically. But delayed presentation due to the embarrassing nature of the injury makes surgical outcome worse. Objectives: This study was conducted to compare results of early and delayed surgical interventions of patients presenting with penile fracture. Methodology: A cross-sectional study was conducted at the department of Urology, in Dhaka Medical College of hospital, Bangladesh from 30th July 2018 to 30th January 2020. Twenty- Seven (27) patients with penile fracture were enrolled in this study. They were diagnosed on the basis of history and clinical findings. They were divided into two groups; early presenter (15 patients) who came within 24 hours and delayed presenter (12 patients) who came after 24 hours. Among the early presenters, 13 patients had unilateral corporeal injury and 2 patients had bilateral corporeal injury. On the other hand, in delayed presenters, 11 patients had unilateral corporeal injury and 1 patient had bilateral corporeal injury. Surgical repair was done in all patients. Results: Patient age range was between 15 to 60 years. The commonest presenting complaints were cracking sound 26 out of 27 (96.30%), penile swelling 24 out of 27 (88.88%), pain 22 out of 27(81.48%) and detumusence during sexual intercourse or an erection 17 out of 27(62.96%), urethra bleeding 3 out 27(11.1%). Among different causes, vigorous intercourse where female on top (62.9%) was the commonest followed by bending during erection (18.5%), masturbation (11.1%) And rolling over bed (7.4%). Out of 15 patients in early group, patients presented with urethral injury. The complications in delayed repair group were, plaque formation 3 out of 15 (20%); penile shaft deformity 2(13.3%); erectile dysfunction 1(6.6%) and skin necrosis 2 (13.3%). But in early repair group only one patient developed skin necrosis which was managed conservatively. Conclusion: Fracture of the penis is a surgical emergency. Immediate surgical repair gives excellent results even in the presence of urethral injury. Early diagnosis by history and clinical examination and timely surgical intervention is essential for better outcome with minimal longterm complications.

Published: July 2024

Background: Retinopathy of prematurity (ROP) is a retinal disease that principally affects preterm infants. It is recognized as the leading cause of preventable blindness and visual impairment in the pediatric population. An increase in survival of very young preterm infants due to the advances in neonatology has subjected them to the risk of developing ROP.
Aims & Objectives: To find out the frequency and problems associated with Retinopathy of Prematurity (ROP) in premature babies.
Materials and Methods: This observational study was conducted at Dhaka Medical College and Hospital from July 2016-December 2016. A total of 73 preterm neonates with gestational age less than 35 weeks and weighing less than 2000 grams at birth, being born or admitted at Dhaka Medical College and Hospital were included in the study. After purposive sampling who had fulfilled the inclusion criteria and screened for ROP at 4 weeks after birth. The data analysis was done to find out the prevalence and problems associated with ROP of premature babies.
Result: A total of 73 neonates were screened. The prevalence of ROP was found to be 54% (n=40); of which 35% were in stage 1 and 35% were in stage 2 and the majority were in zone 3 (50%). The prevalence of ROP between 28-30 weeks of gestation was 75% (n=12) and between 31-34 weeks was 49.12% (n=28). 50% (20) neonates with birth weights less than 1500 grams were found to develop ROP. The prevalence of post-natal problems that predispose to ROP was oxygen therapy, apnea, blood transfusion, and sepsis, and the P-value was significant. Out of ROP-positive cases, 16(40%) need laser photocoagulation.
Conclusion: The prevalence of Retinopathy of Prematurity (ROP)in premature babies is high below 30 weeks of gestational age and birth weight less than 1500 gm. Problems significantly associated with ROP were oxygen therapy, apnea, blood transfusion, and sepsis.

Published: July 2024

Brake pads are crucial for vehicle safety, converting kinetic energy to halt motion. They come in types like organic, semi-metallic, ceramic, and metallic. Beyond automotive, brake pads find application in industries such as aerospace, railways, manufacturing, and wind energy for controlled deceleration and safety. This study is primarily concerned with the quality and appropriateness of ceramic brake pads for automotive applications, which are an essential aspect of braking systems for vehicles. The performance characteristics of ceramic brake pads are well established, and this study explores the variables affecting their quality. Under high pressure, brake pad samples are prepared in the study using Powder Metallurgy (PM), which guarantees superior mechanical qualities by removing interface bonding problems. The samples are then sintered at 2850. Hardness, temperature resistance, wear resistance, and Electron Dispersive Spectroscopy (EDS) analysis are all included in the evaluation to ascertain the make-up and distribution of the materials in the brake pad. EDS sheds light on the degree of sintering and the presence of reinforcements. Heat resistance is evaluated using controlled thermal testing, while wear resistance and hardness are determined through Rockwell hardness testing and wear tests, respectively. These measurements are validated for use in automotive disc braking systems for vehicles and motorcycles. The findings are more reliable thanks to statistical analysis done with MINITAB. The study highlights research gaps in environmentally friendly materials, emerging technology impacts, and long-term brake pad durability.

ABSTRACTObjective: The objective of this study is to comprehend and examine the relationship that exists between employee performance, the work environment, and work motivation. Additionally, the role that job satisfaction plays as a mediator in this relationship will be examined. The research population consists of all 67 employees of the Central Statistics Agency Office of Maluku Province.Methodology: The PLS-SEM approach is utilized to analyze the data, and SmartPLS 3.0 software is employed as tool for statistical testing.Findings: At a 5% level of confidence, the hypotheses H1, H2,H4 and H5 are accepted, and the path coefficient values are positive, but H3 and H6 rejected.Conclusion: Employee performance is positively and significantly impacted by work motivation. Employee performance is positively and significantly impacted by the work environment. Employee performance is unaffected by job contentment, while job satisfaction is unaffected by work motivation. The relationship between work motivation and employee performance is not mediated by job satisfaction. The relationship between work environment and employee performance is mediated by job satisfaction, although it is a negative relationship. This indicates that although job satisfaction has a major impact on employee performance, it degrades the link between motivation and work environment.

Teaching Syntax with CLARIN Corpora and Resources
Authors: Balvet Antonio
Published: July 2024

The recent COVID-19 pandemic has brought online learning to the forefront for learners and teachers. As a consequence, the demand for self-paced and adaptive learning resources has reached unprecedented levels. Fortunately, universities had been using e-learning platforms such as Moodle, or other SCORM-compliant LMS, which has helped make the transition from onsite to on-line learning. However, teachers still have had to design and implement assessment activities in the form of self-correcting activities (true/false, multiple answer questions, mark the words, fill in the blanks questions, etc.). This step has proved to be a major hurdle in the on-site to on-line learning transition, since designing and, most of all, manually editing formative and evaluative assessment activities is a very labour-intensive task. In this article, we present a framework that takes advantage of the corpora and resources available from the LINDAT / CLARIAH-CZ Data & Tools platform in order to generate quizzes and other activities related to syntax. After some background on using NLP for teaching grammar, we present our corpus-to-quiz processing chain, and we outline preliminary results on deploying automatically generated French syntax quizzes in the classroom.

Topics in Periodicals from the Swedish Diabetes Association 1949 – 1990: Extending the Topic Modelling Tool Topics2Themes with a Timeline Visualisation
Authors: Skeppstedt Maria , Aangenendt Gijs , Danilova Vera , Söderfeldt Ylva
Published: July 2024

Existing methods for visualising temporal topic models typically present the information in an aggregated form, and do not offer any possibility to track the specific texts responsible for the change in topic prevalence over time. We present a new type of topic modelling-based timeline visualisation. It still provides an overview with aggregated topic information suitable for distant reading, while also allowing the user to gradually zoom into the image for more detail. At the most detailed level, the individual texts can be reached, which makes it possible to switch to close reading. The timeline visualisation was implemented as an extension of the topic modelling tool Topics2Themes, but this visualisation technique can be adapted to other topic modelling tools and algorithms. We showcase the timeline visualisation on a corpus of periodicals from the Swedish Diabetes Association, which is one of the patient organisation corpora studied within the interdisciplinary project ActDisease. One timeline visualisation was generated for the entire corpus. Additionally, we generated a timeline focusing on the texts that contain the word “dietitian”. The two timelines, including the functionality to zoom into the graphs and reach the texts, were used to analyse the topics and how they vary. It could be concluded that some of the topics and topic timelines were predictable, while others revealed content that might be less expected. These results indicate validity of the method applied, and they also show that this visualisation technique could help us learn something new.
Re-Reading Lists in Historical Newspapers: Digital Insights into an Overlooked Text Type
Authors: Rastinger Nina C.
Published: July 2024

The paper presents an ongoing doctoral project dedicated to periodically published lists in historical newspapers between 1600 and 1850. By employing approaches from Corpus Linguistics and Digital Humanities, the project aims to locate the studied ‘small’ texts within existing digital resources, analyse them with regard to their textual characteristics and evaluate their potentials and challenges for automated information extraction. The article primarily focuses on two key aspects: firstly, on search strategies for locating lists in digital newspaper corpora and collections, and secondly, on a case study into lists of arriving persons published in the Wien[n]erisches Diarium between 1703 and 1725. These empirical investigations reveal that periodically published lists form a central and frequent component of early modern newspapers and offer numerous potentials for Digital Humanities research due to their textual features, such as periodicity, repetitiveness or inherent (semi-)structuredness. In this regard, the paper identifies the overlooked newspaper text type as a data treasure awaiting discovery and underscores the need to investigate ‘small’ newspaper texts on a large scale.

Synthetic Pt-Fe(OH)x catalysts by one-pot method for CO catalytic oxidation
Authors: Luo Yiwei , He Tianyao , Li Guobo , Wu Daishe , Liu Wenming , Zhang Shule , Peng Honggen
Published: July 2024

Catalytic oxidation is used to control carbon monoxide (CO) emissions from industrial exhaust. In this work, The prepared Pta-Fe(OH)x catalysts (x represents the mass fraction of Pt loading (%), a = 0.5, 1 and 2) by the one-pot reduction method exhibited excellent CO catalytic activity, with the Pt2-Fe(OH)x catalyst, 70% and ∼100% CO conversion was achieved at 30°C and 60°C, respectively. In addition, the Pt2-Fe(OH)x catalyst also showed excellent H2O resistance and hydrothermal stability in comparison to the Pt2/Fe(OH)x catalyst prepared by impregnation method. Characterization results showed that the excellent catalytic performance of the catalysts was mainly attributed to the abundant surface oxygen species and Pt0 the presence of H2O, which promoted the catalytic reaction of CO, and Density functional theory (DFT) calculation showed that this was mainly attributed to the catalytic activity of the hydroxyl (-OH) species on Pt2-Fe(OH)x surface, which could easily oxidize CO to -COOH, which could be further decomposed into CO2 and H atoms. This study provides valuable insights into the design of high-efficiency non-precious metal catalysts for CO catalytic oxidation catalysts with high efficiency.

Authors: Liu Guoyong , Xue Jianqin , Wu Kunyu , Wu Songtao , Zhang Boce , Liu Zhanguo , Xing Haoting
Published: July 2024

The Paleogene-Neogene strata in the Western Depression of the Qaidam Basin represent a primary focus for oil and gas exploration and development. Influenced by both terrigenous clastic influx and endogenic carbonate deposition, these strata exhibit significant variation in sedimentary systems and reservoir characteristics. This study comprehensively examines the depositional patterns and reservoir properties of the Paleogene-Neogene sequence across the inner, middle, and outer belts of the basin, employing core analysis, thin section petrography, and physical property assessment of reservoirs. Key findings include 1) The development of a concentric sedimentary system in the Western Depression during the Paleogene-Neogene period, characterized by increased carbonate mineral content and decreased clastic material from the periphery to the center of the basin. 2) Varied sedimentary facies associations across different zones, with the outer belt dominated by fan delta and braided river delta deposits, and the middle and inner belts characterized by near-shore shallow lacustrine carbonates and algal mat deposits, and offshore semi-to deep-lacustrine fine sediments, respectively. 3) The outer belt exhibits reservoirs with favorable physical properties and connectivity, while the inner and middle belts show high heterogeneity, indicating potential for lithological traps and shale oil exploration. These insights offer scientific guidance for further investigation into the depositional systems of lacustrine basins in the Western Depression of the Qaidam Basin and for identifying promising reservoirs.
Prediction of personalised postprandial glycaemic response in type 1 diabetes mellitus
Authors: Xiong Xin , Xue Yuxin , Cai Yunying , He Jianfeng , Su Heng
Published: July 2024

Objectives

Patients with type 1 diabetes (T1D) face unique challenges in glycaemic control due to the complexity and uniqueness of the dietary structure in China, especially in terms of postprandial glycaemic response (PPGR). This study aimed to establish a personalized model for predicting PPGR in patients with T1D.

Materials and methods

Data provided by the First People’s Hospital of Yunnan Province, 13 patients with T1D, were recruited and provided with an intervention for at least two weeks. All patients were asked to wear a continuous glucose monitoring (CGM) device under free-living conditions during the study period. To tackle the challenge of incomplete data from wearable devices for CGM measurements, the GAIN method was used in this paper to achieve a more rational interpolation process. In this study, patients’ PPGRs were calculated, and a LightGBM prediction model was constructed based on a Bayesian hyperparameter optimisation algorithm and a random search algorithm, which integrated glucose measurement, insulin dose, dietary nutrient content, blood measurement and anthropometry as inputs.

Results

The experimental outcomes revealed that the PPGR prediction model presented in this paper demonstrated superior accuracy (R=0.63) compared to both the carbohydrate content only model (R=0.14) and the baseline model emulating the standard of care for insulin administration (R=0.43). In addition, the interpretation of the model using the SHAP method showed that blood glucose levels at meals and blood glucose trends 30 minutes before meals were the most important features of the model.

Conclusion

The proposed model offers a heightened precision in predicting PPGR in patients with T1D, so it can better guide the diet plan and insulin intake dose of patients with T1D.

Classical multilevel inverter (MLI) topologies have gained widespread interest in industry and academia because of the improved qualities they offer over their two-level counterparts. MLIs are characterized by reduced Total Harmonic Distortion (THD) and high power conversion efficiency. Classical MLI topologies, however, are not without drawbacks; generally, they require many components as the number of output waveform levels is increased, resulting in high cost and complex implementation. Furthermore, MLIs based on flying capacitors have issues with capacitor voltage balancing and high inrush currents. As a result, this has prompted researchers to develop reduced component count (RCC) or reduced switch count (RSC) and hybrid topologies to achieve high power quality, but at reduced cost and complexity in comparison to classical MLI topologies. This article evaluates the merits and demerits of recently proposed reduced switch count and hybrid topologies, identifies challenges and opportunities, and proposes further research and development for the improvement of multilevel inverters. This review paper will be helpful to those conducting research in the field of MLI technology.

In recent years, the ever-rising penetration of distributed photovoltaics (PV) power has presented substantial challenges in power system dispatch due to its inherent randomness and unpredictability. To bridge this gap, this paper proposes a two-stage robust optimization method for power system security dispatch considering traditional generators as well as flexible resources, such as load demand response and energy storage systems. Specifically, a price-based demand response model is established to optimize the system’s load curve during a day. On this basis, a two-stage optimization problem for day-ahead and intra-day power system dispatch model is proposed. The dispatch objective is to minimize the overall cost in worst-case scenarios through properly scheduling unit commitment (UC) as well as flexible resources in each dispatch interval. Column and constraint generation (C&CG) algorithm is adopted for problem solving. The effectiveness of the proposed method is validated by case studies based on a modified 6-node system and a 24-node system. Simulation results indicate that through appropriately scheduling the energy storage system and load demand response, the proposed dispatch method can significantly reduce the total operation cost of a PV rich power system, which in turn facilitates the integration of PV power.

The application of computer vision in fish identification facilitates researchers and managers to better comprehend and safeguard the aquatic ecological environment. Numerous researchers have harnessed deep learning methodologies for studying fish species identification. Nonetheless, this endeavor still encounters challenges such as high computational costs, a substantial number of parameters, and limited practicality. To address these issues, we propose a lightweight network architecture incorporating deformable convolutions, termed DeformableFishNet. Within DeformableFishNet, an efficient global coordinate attention module (EGCA) is introduced alongside a deformable convolution network (EDCN/EC2f), which is grounded in EGCA, to tackle the deformation of fish bodies induced by swimming motions. Additionally, an EC2f-based feature pyramid network (EDBFPN) and an efficient multi-scale decoupling head (EMSD Head) are proposed to extract multi-scale fish features within a lightweight framework. DeformableFishNet was deployed on our freshwater fish dataset, with experimental outcomes illustrating its efficacy, achieving a mean average precision (mAP) of 96.3%. The model comprises 1.7 million parameters and entails 4.7 billion floating-point operations (FLOPs). Furthermore, we validated DeformableFishNet on three public underwater datasets, yielding respective mAPs of 98%, 99.4%, and 83.6%. The experiments show that DeformableFishNet is suitable for underwater identification of various scenes.

Published: July 2024

Introduction

Obstructive sleep apnea (OSA) is frequently associated with airflow limitation (AFL). However, information on the prevalence of and factors associated with likely OSA in individuals with AFL in Korea is limited.

Methods

Data from the 2019 Korea National Health and Nutrition Examination Survey (KNHANES) were used, and 3,280 individuals (2,826 individuals without AFL and 454 individuals with AFL) were included. AFL was defined as forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) < 0.7. A score ≥ 5 on the STOP-BANG questionnaire was used to identify individuals with likely OSA. The prevalence of likely OSA was compared between individuals with and without AFL. In addition, factors associated with likely OSA in individuals with AFL were evaluated using multivariable logistic regression analysis.

Results

Of 3,280 individuals, 13.8% had an AFL. The prevalence of likely OSA was significantly higher in individuals with AFL than in individuals without AFL (9.2% vs. 5.0%, p = 0.014). Among 454 individuals with AFL, obesity (adjusted odds ratio [aOR] = 14.78, 95% confidence interval [CI] = 4.20–52.02) was most strongly associated with likely OSA, followed by heavy alcohol consumption (aOR = 4.93, 95% CI = 1.91–12.70), hypertension (aOR = 4.92, 95% CI = 1.57–15.46), overweight (aOR = 4.71, 95% CI = 1.76–12.64), college graduate (aOR = 4.47, 95% CI = 1.10–18.22), and history of pulmonary tuberculosis (aOR = 3.40, 95% CI = 1.06–10.96).

Conclusion

In Korea, approximately 1 in 10 individuals with AFL had likely OSA. Overweight and obesity, heavy alcohol consumption, high educational level, hypertension, and history of pulmonary tuberculosis were associated with likely OSA in individuals with AFL.

Published: July 2024

Objective

Based on machine learning method, four types of early postoperative frailty risk prediction model of enterostomy patients were constructed to compare the performance of each model and provide the basis for preventing early postoperative frailty of elderly patients with enterostomy.

Methods

The prospective convenience sampling method was conducted and 362 early postoperative enterostomy patients were selected in three hospitals from July 2020 to November 2023 in Shanghai, four different prediction models of Support Vector Machine (SVM), Bayes, XG Boost, and Logistic regression were used and compared the test effects of the four models (MCC, F1, AUC, and Brier index) to judge the classification performance of the four models in the data of this study.

Results

A total of 21 variables were included in this study, and the predictors mainly covered demographic information, stoma-related information, quality of life, anxiety and depression, and frailty. The validated models on the test set are XGBoost, Logistic regression, SVM prediction model, and Bayes on the MCC and F1 scores; on the AUC, XGBoost, Logistic regression, Bayes, and SVM prediction model; on the Brier scores, Bayes, Logistic regression, and XGBoost.

Conclusion

XGBoost based on machine learning method is better than SVM prediction model, Logistic regression model and Bayes in sensitivity and accuracy. Quality of life in the early postoperative period can help guide clinical patients to identify patients at high risk of frailty and reduce the incidence of early postoperative frailty in elderly patients with enterostomy.

Published: July 2024

Background

Schisanlactone E, also known as XueTongSu (XTS), is an active compound extracted from the traditional Tujia medicine Kadsura heteroclita (“XueTong”). Recent studies highlight its anti-inflammatory and antioxidant properties, yet the mechanisms of XTS’s therapeutic effects on Alzheimer’s disease (AD) are unclear. This study aims to elucidate the therapeutic efficacy and mechanisms of XTS in AD.

Methods

Ten C57BL/6 mice were assigned to the control group (NC), and twenty APP/PS1 transgenic mice were randomly divided into the model group (M) (10 mice) and the XTS treatment group (Tre) (10 mice). After an acclimatization period of 7 days, intraperitoneal injections were administered over a 60-day treatment period. The NC and M groups received saline, while the Tre group received XTS at 2 mg/kg. Learning and memory abilities were assessed using the Morris Water Maze (MWM) test. Histopathological changes were evaluated using hematoxylin and eosin (HE) and Nissl staining, and immunofluorescence was used to assess pathological products and glial cell activation. Cytokine levels (IL-1β, IL-6, TNF-α) in the hippocampus were quantified by qPCR. 16S rDNA sequencing analyzed gut microbiota metabolic alterations, and metabolomic analysis was performed on cortical samples. The KEGG database was used to analyze the regulatory mechanisms of XTS in AD treatment.

Results

XTS significantly improved learning and spatial memory in APP/PS1 mice and ameliorated histopathological changes, reducing Aβ plaque aggregation and glial cell activation. XTS decreased the expression of inflammatory cytokines IL-1β, IL-6, and TNF-α. It also enhanced gut microbiota diversity, notably increasing Akkermansia species, and modulated levels of metabolites such as isosakuranetin, 5-KETE, 4-methylcatechol, and sphinganine. Pathway analysis indicated that XTS regulated carbohydrate metabolism, neuroactive ligand-receptor interactions, and alanine, aspartate, and glutamate metabolism, mitigating gut microbiota dysbiosis and metabolic disturbances.

Conclusion

XTS ameliorates cognitive deficits, pathological changes, and inflammatory responses in APP/PS1 mice. It significantly modulates the gut microbiota, particularly increasing Akkermansia abundance, and influences levels of key metabolites in both the gut and brain. These findings suggest that XTS exerts anti-AD effects through the microbial-gut-brain axis (MGBA).
