Background

The use of digital online teaching media in improving the surgical skills of medical students is indispensable, yet it is still not widely explored objectively. The first-person–view online teaching method may be more effective as it provides more realism to surgical clerkship students in achieving basic surgical skills.

Objective

This study aims to objectively assess the effectiveness of the first-person–view live streaming (LS) method using a GoPro camera compared to the standard face-to-face (FTF) teaching method in improving simple wound suturing skills in surgical clerkship students.

Methods

A prospective, parallel, nonblinded, single-center, randomized controlled trial was performed. Between January and April 2023, clerkship students of the Department of Surgery, Pelita Harapan University, were randomly selected and recruited into either the LS or FTF teaching method for simple interrupted suturing skills. All the participants were assessed objectively before and 1 week after training, using the direct observational procedural skills (DOPS) method. DOPS results and poststudy questionnaires were analyzed.

Results

A total of 74 students were included in this study, with 37 (50%) participants in each group. Paired analysis of each participant’s pre-experiment and postexperiment DOPS scores revealed that the LS method’s outcome is comparable to the FTF method’s outcome (LS: mean 27.5, SD 20.6 vs FTF: mean 24.4, SD 16.7; P=.48) in improving the students’ surgical skills.

Conclusions

First-person–view LS training sessions could enhance students’ ability to master simple procedural skills such as simple wound suturing and has comparable results to the current FTF teaching method. Teaching a practical skill using the LS method also gives more confidence for the participants to perform the procedure independently. Other advantages of the LS method, such as the ability to study from outside the sterile environment, are also promising. We recommend improvements in the audiovisual quality of the camera and a stable internet connection before performing the LS teaching method.
Research on Traditional Chinese Medicine: Domain Knowledge Graph Completion and Quality Evaluation (Preprint)
Authors: Liu Chang , Li Zhan , Li Jianmin , Qu Yiqian , Chang Ying , Han Qing , Cao Lingyong , Lin Shuyuan
Published: August 2024

BACKGROUND

Knowledge graphs (KGs) can integrate domain knowledge into a traditional Chinese medicine (TCM) intelligent syndrome differentiation model. However, the quality of current KGs in the TCM domain varies greatly, related to the lack of knowledge graph completion (KGC) and evaluation methods.

OBJECTIVE

This study aims to investigate KGC and evaluation methods tailored for TCM domain knowledge.

METHODS

In the KGC phase, according to the characteristics of TCM domain knowledge, we proposed a 3-step “entity-ontology-path” completion approach. This approach uses path reasoning, ontology rule reasoning, and association rules. In the KGC quality evaluation phase, we proposed a 3-dimensional evaluation framework that encompasses completeness, accuracy, and usability, using quantitative metrics such as complex network analysis, ontology reasoning, and graph representation. Furthermore, we compared the impact of different graph representation models on KG usability.

RESULTS

In the KGC phase, 52, 107, 27, and 479 triples were added by outlier analysis, rule-based reasoning, association rules, and path-based reasoning, respectively. In addition, rule-based reasoning identified 14 contradictory triples. In the KGC quality evaluation phase, in terms of completeness, KG had higher density and lower sparsity after completion, and there were no contradictory rules within the KG. In terms of accuracy, KG after completion was more consistent with prior knowledge. In terms of usability, the mean reciprocal ranking, mean rank, and hit rate of the first N tail entities predicted by the model (Hits@N) of the TransE, RotatE, DistMult, and ComplEx graph representation models all showed improvement after KGC. Among them, the RotatE model achieved the best representation.

CONCLUSIONS

The 3-step completion approach can effectively improve the completeness, accuracy, and availability of KGs, and the 3-dimensional evaluation framework can be used for comprehensive KGC evaluation. In the TCM field, the RotatE model performed better at KG representation.

Published: August 2024

In the present study, the concentrations of nine heavy metals (Cr, Cd, Cu, Mn, Pb, Co, Fe, Ni, and Zn) in roadside soils were measured by flame atomic absorption spectroscopy (FAAS). Roadside soils were collected during the summer semester from Mafraq, Jordan (N = 97). Four sampling sites were selected for this study, including commercial area, industrial area, residential area, and Irbid-Mafraq highway. The average metal concentrations (±SD) in the collected soils were 16840 (± 9479), 40 (± 40), 99 (± 44), 478 (± 155), 60 (± 62), 2 (± 1), 73 (± 23), 14 (± 5), and 45 (± 13) mg/kg for Fe, Cu, Zn, Mn, Pb, Cd, Cr, Co, and Ni, respectively. The results of this study revealed that the highest Mn, Cu, Co, Ni, Zn, Fe, and Pb concentrations were found in the industrial area, and the highest Cd concentration was found at the Irbid-Mafraq highway. The values of the enrichment factors for Zn, Cr, Cd, and Ni in the collected roadside soils were found to be higher than 10, confirming the presence of anthropogenic pollution in the studied areas. The results of this study were also compared with other studies performed in different countries in the world.

Authors: BKV Vismayaa Yadav
Published: August 2024

Abstract: Forecasting stock prices is a very difficult task due to the sudden and volatile nature of financial markets. This paper reviews recent developments in the use of the XGBoost algorithm for stock price forecasting. XGBoost, a robust and efficient gradient enhancement implementation, has demonstrated excellent performance in a variety of predictive modeling environments. The analysis uses various experimental methods, including data generation, feature engineering, model training, and validation procedures. It also compares the performance of XGBoost with other machine learning algorithms. The findings show that XGBoost is able to capture complex non-linear relationships in stock market data, resulting in improved forecasting accuracy. However, challenges such as excessive packaging and reliance on quality remain. The paper presents possible future research directions, including the integration of mixed models, the use of new data sources, and the enhancement of model interpretation and real-time predictive capabilities.
Does the Government have the authority to annul Regional Regulations?
Authors: Sukardi Sukardi , Wardana Dodi Jaya
Published: August 2024

The existence of a dualism in the authority to annul Regional Regulations by the Supreme Court through judicial review and by the Government through executive review has been a significant issue. However, through the Constitutional Court Decisions Number 137/PUU-XIII/2015 and Number 56/PUU-XIV/2016, the Government's authority to annul Regional Regulations has been revoked, transferring this authority to the Supreme Court. This article discusses the ratio decidendi of the Constitutional Court decisions regarding the authority to annul Regional Regulations and the implications of these decisions on the mechanism for supervising Regional Regulation. This normative juridical research employs conceptual, case, and statutory approaches. The analysis shows that the decisions of the Constitutional Court Numbers 137/PUU-XIII/2015 and 56/PUU-XIV/2016 led to a significant reduction in the quality and execution power of the Supreme Court decisions concerning judicial reviews, creating potential policy conflicts between central and regional governments, and between petitioners and local governments, and hindering the supervision of Regional Regulations due to the Supreme Court's reactive nature in awaiting applications.

During the 13th-14th centuries when the Yuan dynasty existed, the Mongolian and Chinese nationalities were under the same government and had extensive relations in terms of politics, economy, religion and culture, many Mongolian words occurred in the Yuan Plays of that time. Mongolian words encountered in the Yuan Plays’ scripts of the Yuan Dynasty were phonetically recorded in Chinese, making it possible to know the pronunciation of Mongolian words at that time. Therefore, through the phonetic system of the Mongolian and Chinese languages of the XIII-XIV centuries, we compared these Mongolian words in historical sources like “Mongolian Secret History”, “Hua-i i-yu Chinese-Mongolian dictionary”, “Zhong yuan yin yun (中原音韵)” , “Historical Linguistics of the Mongolian Language”, “Phonology of the Chinese Language (汉语音韵)”, “Sketches of the History of the Chinese Language (汉语史稿)”, and after analysing them, the phonetics features are clarified.

Published: August 2024

Aceh has a great potential in coastal areas because Aceh has a large source of marine biota, especially seaweed. The coast that has great potential for seaweed growth is Ulee Lheue Beach. Ulee Lheue Beach is a tourist area and port, so it tends to be exposed to heavy metals. Seaweed can absorb heavy metals easily and is used as a bioindicator of environmental pollution. The aim of this research was to measure the heavy metal content of Cu and Zn from the green seaweeds Caulerpa taxifolia and Caulerpa racemosa. The research method was carried out using a hydrothermal analysis digestion process using a hydrothermal-microwave analysis tool for 30 minutes. Metal content was analyzed using an Atomic Absorption Spectrophotometer (SSA). The results showed that the levels of heavy metals of Zn and Cu in Caulerpa taxifolia seaweed were 11.05 and 3.65 ppm. Furthermore, the levels of heavy metals Zn and Cu in the seaweed Caulerpa racemosa were 18.46 and 12.26 ppm. It can be concluded that Caulerpa taxifolia and Caulerpa racemosa can absorb heavy metals.

Published: August 2024

Introduction: Borreria spinosa is a herbaceous plant considered a weed in agricultural crops, although it also has potential in apiculture. Despite its agronomic importance, its cytogenetic and palynological traits are poorly known. Objective: To do the cytogenetic characterization of B. spinosa, describe the morphology of its pollen grains, and estimate their potential viability. Methods: We collected plant material in Santiago del Estero, Argentina, in May 2017 and used classical methods (8-hydroxyquinoline and Farmer for mitosis and meiosis; viability with Müntzing; pollen morphology with nonacetolysed and acetolysed techniques, and SEM). Results: B. spinosa has a chromosome number of 2n = 56, with a karyotype of 46 m + 10 sm. Meiotic abnormalities mainly include chromosomes outside the equatorial plate, lagging chromosomes, and cytomixis. Pollen grains are small to medium-sized, suboblate to oblate-spheroidal, with a viability of 70%. This is a tetraploid species, most chromosomes are metacentric or submetacentric; and it has irregular meiotic behavior and cytomixis, with concomitant low viability in pollen grains. Conclusion: In B. spinose, pollen grains have similar characteristics to other species of the genus Borreria.

This study introduces a machine vision technique that utilizes an artificial
neural network (ANN) to develop a predictive model for classifying dried
grapes during the drying process. The primary objective of this model is to
mitigate the burden placed on the operator and minimize the occurrence of
over-dried items. The present study involves the development of a model that
is constructed using the characteristics of grape color and shape. There
exist two distinct categories of labels for grapes: fully desiccated grapes,
commonly referred to as raisins, and grapes that have undergone partial
drying. Image processing is utilized to collect and observe five significant
characteristics of grapes during the drying process. The findings indicate a
significant decrease in the levels of red, green, and blue colors (RGB)
during the initial 15-hour drying period. The predictive model extracts
properties such as RGB color, roundness, and shrinkage from the image while
it undergoes the drying process. The artificial neural network (ANN) model
achieved a level of accuracy performance of 78%. In this work, the
dehydration apparatus will cease operation in an automated manner whenever
the entirety of the grapes situated on the tray have been projected to
undergo the transformation into raisins.
Correlations of spheno-occipital synchondrosis, cervical vertebrae, midpalatal suture, and third molar maturation stages
Authors: Booth Evan , Viana Grace , Shirazi Sajjad , Miller Steven , Sellke Terry , Elnagar Mohammed , Viana Marlos , Atsawasuwan Phimon
Published: August 2024

Objectives

To estimate the joint correlations among cervical vertebrae maturation (CVM), spheno-occipital synchondrosis (SOS), midpalatal suture maturation (MPS), and third molar mineralization (TMM) and to assess the predictive potential of SOS on CVM and MPS.

Materials and Methods

570 pretreatment cone-beam computed tomogram (CBCT) scans from three private practices were analyzed, and MPS, CVM, SOS, and TMM stages were categorized and recorded by two independent investigators. Intra- and inter-rater reliability tests were evaluated with weighted Cohen’s kappa tests. Spearman correlation coefficients for ordinal data were used to estimate the pairwise correlations among SOS, CVM, MPS, and TMM. To evaluate if SOS could predict CVM and MPS, ordinal regression models were estimated and cross-validated.

Results

The analysis demonstrated a robust positive correlation between SOS and CVM (r = 0.845) and between SOS and MPS (r = 0.742). A significant correlation was also observed between CVM and MPS (r = 0.659). Further correlations were identified between TMM and SOS (r = 0.444), TMM and MPS (r = 0.392), and TMM and CVM (r = 0.358). Ordinal regression models indicated the potential of using SOS as a predictive marker for CVM and MPS stages.

Conclusions

With a comprehensive analysis, SOS is strongly correlated with CVM and MPS, and SOS stage can be used to predict CVM and MPS using ordinal regression. Since MPS stages are challenging to categorize due to their anatomy, this finding suggests a diagnostic tool using SOS stages or when more information on skeletal maturity of the patient is desired.
Surface tension derivation from laser-generated keyholes
Authors: Volpp Joerg , Zaiss Felix , Hagenlocher Christian , Graf Thomas
Published: August 2024

Surface tension is an essential material property that defines many aspects of thermal processes involving liquids. Metal materials have high melting temperatures, and surface tension could often be measured around melting temperature and is, therefore, known for many pure materials and simple material systems. However, high-energy input during laser, electron beam, or plasma processes is known to increase the material temperatures far above the melting point. To build theoretical models, simulate processes, and increase process understanding, surface tension values at those high temperatures would be beneficial to know. However, it can be difficult to create stable circumstances and measure surface tension in those conditions. Therefore, it is suggested in this work to indirectly derive surface tension values from the pressure balance inside keyholes created during laser deep penetration processing. A variety of different keyhole shapes were created using dynamic beam shaping by means of coherent beam combining. From the observed keyhole shapes using inline x-ray observations, temperature distributions on the keyhole walls were calculated using ray tracing. The temperature defines the local recoil pressure that counteracts the surface tension pressure, which contains the surface tension value as the only unknown variable. At increasing temperatures above the boiling point, an increasing surface tension was observed.

Published: August 2024

En este trabajo nos interesa mostrar la participación del puerto de Talcahuano en el comercio ballenero global durante la primera mitad del siglo XIX, con sus armadores, comerciantes, tripulantes, estibadores, aduanas, instalaciones portuarias, equipamiento, etc. Examinaremos las características del puerto de Talcahuano y las particularidades de su industria ballenera. Estudiaremos los datos que suministra el censo de población de 1842 y los informes comerciales provenientes de la aduana del puerto. También resulta relevante discutir la manera como la sociedad penquista enfrenta las dificultades experimentadas por el declive de la industria en la segunda mitad del siglo XIX y la disminución de la presencia de balleneros extranjeros en la bahía. Usamos como fuente de información las descripciones elaboradas por viajeros que estuvieron en el puerto de Talcahuano en el siglo XIX, los datos que aparecen en el Censo de 1854, y las noticias sobre esta problemática comunicadas en los periódicos de Concepción en la misma época.
Repasiris y azogueros en la quebrada: expansión y declive de los espacios productivos de la proto-industria minera (Tarapacá, 1718-1845)
Authors: Lo Chávez Damián ,   Universidad de Tarapacá, Chile
Published: August 2024

En el siglo XVIII comenzó un ciclo minero basado en la producción y exportación de minerales procesados en oficinas manufactureras premecánicas en Tarapacá, extremo sur del virreinato del Perú. Las fuerzas productivas regionales se organizaron en una cadena de explotación entre propietarios mineros, representantes del capital comercial y trabajadores subalternos configurando un duradero régimen de producción minera de carácter protoindustrial. El temprano centro directivo de las operaciones mineras fue la quebrada de Tarapacá y el pueblo capital de San Lorenzo. Las contradicciones internas redistribuyeron estas fuerzas productivas gatillando una diáspora desde la precordillera hacia la pampa, donde operaron las oficinas polivalentes de beneficio minero, productoras de plata, salitre y pólvora a partir de 1765. Proponemos este proceso como un antecedente necesario para comprender en perspectiva histórica la acelerada litoralización de Tarapacá en la segunda mitad del siglo XIX e interpretar la minería tarapaqueña como un largo ciclo minero, discutiendo la división artificial de la historia regional en un ciclo de la plata colonial y un ciclo del salitre republicano.
ROLE OF MULTIMODAL METAPHOR IN CONSTRUCTING IMAGE OF CORPORATE LEADER ON BUSINESS MAGAZINE COVERS
Authors: Oleksii Dovbnya
Published: August 2024

This paper contributes to the relatively nascent field of multi-modal metaphor research, specifically focusing on the manifestation of the given type of metaphors on the covers of business magazines. For the purpose of this study, a sample of covers from prominent business magazines (including Bloomberg Businessweek, Time Magazine, and The Economist) was collected and analyzed. In this research paper, four types of multi-modal metaphors have been distinguished based on the means of encoding source domains and target domains in verbal and pictorial modes. The study was performed within the theoretical framework of critical metaphor analysis. After analyzing the articles, it has been determined that multi-modal metaphors on business magazine covers can be based on image-schema level metaphors such as POWER IS UP as well as more complex domain-level metaphors such as BUSINESS LEADER IS A RELIGIOUS FIGURE. Covers that rely on multi-modal metaphors help to define the personality of a certain magazine.

Authors: Kalashnikov Valeriy
Published: August 2024

Clinical and Doppler examination of 146 patients was carried out young age (18–44 years, including men – 75, women – 71) with cervicogenic headache. All patients were divided into two clinical groups: group 1 – cervicocranialgia – 82 patients; group 2 – posterior cervical sympathetic Barre-Lieou syndrome – 64 patients. By help triplex transcranial scanning has been studied high- speed blood flow indicators in the supraocular and vertebral veins, basal veins of Rosenthal, sinus rectus, as well as reactivity coefficients in the vertebral veins, basal veins of Rosenthal and direct sinus at applications and orthostatic and antiorthostatic functional loads. All patients were determined Doppler and signs of cerebral venous dyscirculation, mainly in the vertebral veins. Signs of venous dyscirculation were manifested in the vertebral veins and sinus rectus in patients with cervicocranialgia, as well as in vertebral veins in patients with Barre-Lieou syndrome. Leading pattern there was a violation of autoregulation of cerebral venous blood flow hyporeactivity to orthostatic and antiorthostatic loading in the vertebral veins, more pronounced in patients with cervicocranialgia. Easy hyperreactivity to antiorthostatic load on the basal veins of Rosenthal and sinus rectus in patients of both groups indicates a violation of the neurogenic mechanism in the regulation of venous blood flow.

Pressure sores are a serious complication of multi morbidity and lack of mobility. Pressure injuries are commonly encountered in geriatric patients. Certain well-recognized risk factors, such as immobility and incontinence, may predispose to the development of pressure injury (PI); consequently, risk factor modification is an important aspect of prevention and treatment. One of the fundamental documentation details when describing a wound is the use of the appropriate staging system. Each staging system is unique to a wound’s type, should align with your description of the wound, and be integrated into your documentation details. For research purpose more improvements in staging with inclusion of infection, progression of ulcer and major risk factors on existing stages of only depth has been suggested by Kumar. This will have bearing on the prognosis of the disease and management protocol and hence better outcome of research work. The most extensive published experiences with pressure sore treatment are those of Conway and Griffith (1000 cases) and Dansereau and Conway’s update of the Bronx Veterans Administration Hospital data (2000 cases). But with new technologies of wound care more research is required to standardized the prevention and management of pressure injury. There is need to reduce cost of the care for long term compliance. For research purpose more improvements in staging with inclusion of infection, progression of pressure injury and major risk factors in existing staging (four stages) of depth only has been suggested by Kumar. This will have bearing on prognosis of the disease and management protocol and hence, better outcome of research work. The classification has been updated by inclusion of suspected deep tissue injury. This study highlights the role Kumar classification applied on a case of sacral pressure injury.

Climate change has been a global issue for the past decades. It has impacted numerous aspects in landslide, particularly in the slope stability. The soil mass rupture leads to damage to infrastructure and death. Thus, any prevention is urgently needed to minimize the risk.  Forecasting the hazards is part of disaster management. The Initial step of this action is forecasting the rainfall due to climate change for the next 20 years since 2010, given that most of the landslide hazards in Paweden and Kalilunjar are triggered by rainfall.  This study uses CORDEX-SEA to obtain the rainfall forecasting data as the input to simulate the slope stability. The rainfall seepage is performed to obtain slope safety factor by using Geo-studio. Two chosen sub-districts in Banjarnegara, Paweden and Kalilunjar, are expected to experience more extreme daily rainfall by the end of 2030 compared to 2010 conditions. This study also shows that all rainfall cases trigger a slope failure (FS<1.2). This study is expected to support the local government in deciding the next hazard mitigation plan.
Cosmologia evolucionária peirciana e complexidade
Authors: Santos Romilson Marco
Published: August 2024

Este artigo discute como a cosmologia evolucionária de Charles S. Peirce e as ciências da complexidade revelam um sistema aberto de criatividade imprevisível, ao mesmo tempo que se estabelecem como fundamentos de uma criatividade indeterminista da complexidade. Nesse sentido, em um primeiro momento, salienta-se a relação entre os estudos peircianos e as ciências da complexidade; posteriormente, demonstra-se, na cosmologia evolucionária peirciana, os elementos imprevisíveis de criatividade que se desenvolverão nas ciências da complexidade.
Endodontic Microsurgery of a Mandibular Molar Using a Dynamic Navigation System (DNS) and Cortical Window Technique: A Case Report

Published: August 2024

Recent advancements in endodontic surgery have significantly improved outcomes through enhanced technology, including digital planning, cone-beam computed tomography (CBCT), and operating microscopes. The integration of dynamic navigation systems (DNS) has particularly transformed endodontic microsurgery (EM) by providing real-time guidance and precision. This case report explores the application of DNS in a clinical case of EM involving a mandibular first molar with symptomatic apical periodontitis. A 36-year-old male patient presented with masticatory pain in the lower left quadrant. Radiographic and CBCT evaluations revealed an underfilled mesiolingual canal and a periapical lesion. The surgical procedure utilized DNS for precise osteotomy and apicectomy, guided by the Navident® system and incorporating the cortical window technique. Postoperative care included antibiotic therapy and follow-up appointments, demonstrating successful periapical healing at 21 months. DNS technology significantly enhances precision and conservativeness in EM, allowing for real-time guidance and minimizing iatrogenic risks. The cortical window technique, combined with DNS, facilitates effective root access while preserving bone structure. Despite its advantages, DNS is associated with high costs and a steep learning curve. Future research should focus on evaluating the long-term clinical outcomes of DNS, improving system usability, and exploring its applications in other endodontic procedures. This case report demonstrates the successful use of DNS in conjunction with the cortical window technique for EM, achieving favorable clinical outcomes and promoting accelerated healing. Further studies are needed to validate the broader clinical utility of DNS and to refine its integration into routine practice.
