Classification methodology and feature selection to assist fault location in power distribution systems
Authors: Mora-Flórez Juan José , Morales-España Germán , Pérez-Londoño Sandra 
Published: July 2024

A classification methodology based on Support Vector Machines (SVM) is proposed to locate the faulted zone in power distribution networks. The goal is to reduce the multiple-estimation problem inherent in those methods that use single end measures (in the substation) to estimate the fault location in radial systems. A selection of features or descriptors obtained from voltages and currents measured in the substation are analyzed and used as input of the SVM classifier. Performance of the fault locator having several combinations of these features has been evaluated according to its capability to discriminate between faults in different zones but located at similar distance. An application example illustrates the precision, to locate the faulted zone, obtained with the proposed methodology in simulated framework. The proposal provides appropriate information for the prevention and opportune attention of faults, requires minimum investment and overcomes the multiple-estimation problem of the classic impedance based methods.

Electrochemical assessment of weathering steels under simulated laboratory conditions
Authors: Jaramillo Beatriz , Calderón Jorge Andrés , Castaño Juan Guillermo 
Published: July 2024

In the last decades weathering steels have became important structural materials in the construction of civil works due to their low rate of corrosion when exposed to urban and industrial atmospheres. The excellent anticorrosive properties of the weathering steels have been attributed to the nature and structure of the rust formed on the material surfaces when certain favorable conditions are present. In this work a study of the characteristics of the rust initially formed on weathering steels is presented. The study was performed on weathering steels of different nature and different surface conditions: nude, pre-rusted and galvanized, and exposed to conditions that simulate urban and industrial atmospheres. The analysis was carried out by means of electrochemical techniques, such as evaluation of the open-circuit potential and electrochemical impedance during the first two months of exposure.

Authors: Chandrakar Mayank 
Published: July 2024

Oral health affects quality of life and can increase risk for systemic diseases. Dental caries and tooth loss has been reported in patients with Diabetes. There is a ‘bi-directional’ relationship between Type 2 Diabetes Mellitus and periodontal disease.600 subjects, age group of 25-50 years was selected from 4 zones by in Durg city. From each zone one ward’s house was randomly selected. 150 subjects were examined from selected wards of each zone. Blood Glucose Test was done by using Glucometer. Periodontal status and dental caries status was recorded using CPI Index and W.H.O. Dentition Status and Treatment Needs. Statistical analyses were performed using SPSS 16.0. Descriptive statistics were calculated. Fisher’s exact test, t-test, One way ANOVA, Mann Whitney U Test and Kruskal Wallis Test were applied.Mean number of CPI score (2.88 + 0.56) was higher in T2DM subjects as compared to Nondiabetic subjects (2.05 + 0.68). Mean number of Loss of Attachment Score (0.90 + 0.49) was greater in T2DM subjects than in Nondiabetic subjects (0.24 + 0.43). There was no statistically significant difference in Mean Decayed Teeth between T2DM subjects (1.41 + 1.67) and Nondiabetic subjects (1.26 + 1.84) (p &#62; 0.05). DMFT was statistically significant when compared between the diabetic and non-diabetic subjects (p &#60; 0.05). Diabetic subjects were affected by a severe degree of periodontal disease in comparison to non-diabetic subjects. Dental Caries was not found to be significantly different between diabetics and non-diabetics.
Repeated complete atrioventricular block during remifentanil administration in a pediatric patient with brain tumor and acute hydrocephalus: a case report
Authors: Ura Akihiro , Fujii Keisuke , Tanioku Tadashi , Kawamata Tomoyuki 
Published: July 2024

Abstract

Background
Remifentanil, an ultra-short-acting µ-opioid receptor agonist, is commonly used for anesthetic management due to excellent adjustability. Remifentanil is known to cause sinus bradycardia, however, because it has a direct negative chronotropic effect on the cardiac conduction system and there is an indirect negative chronotropic effect via the parasympathetic nervous system.
Case presentation
An 8-year-old Japanese boy was diagnosed with acute hydrocephalus due to a brain tumor in the fourth ventricle and underwent emergency surgery. Imaging examination showed brainstem compression. Endoscopic third ventriculostomy and ventriculoperitoneal shunt surgery were scheduled. Remifentanil was started during induction of general anesthesia, but electrocardiogram showed sinus bradycardia, then Wenckebach-type atrioventricular block, and then complete atrioventricular block. Remifentanil was immediately discontinued, and we administered atropine sulfate. Complete atrioventricular block was restored to sinus rhythm. When remifentanil was restarted, however, the electrocardiogram again showed sinus bradycardia, Wenckebach-type atrioventricular block, and then complete atrioventricular block. Remifentanil was again immediately discontinued, we administered adrenaline, and then complete atrioventricular block was restored to sinus rhythm. Fentanyl was used instead of remifentanil with continuous infusion of dopamine. There has since been no further occurrence of complete atrioventricular block.
Conclusions
This is the first known case of complete atrioventricular block in a pediatric patient with increased intracranial pressure seemingly caused by administration of remifentanil.

Abstract

Background
In Thai traditional history, Ya-Kao (YK) is a traditional medicine used to relieve fever. Several Thai folk healers have recommended the use of YK for COVID-19 during pre-treatment, treatment, and post-treatment. The Department of Thai Traditional and Alternative Medicine (DTAM) has accepted YK for COVID-19-infected patients and has been observing its effectiveness in a clinical study. Fourteen plants are the main raw materials of the YK formula, which currently lacks scientific information to support its properties. The study aims to investigate the chemical profile of YK and its biological properties by measuring the antibacterial and anti-inflammatory effects, in vitro study.
Methods
YK investigated the chemical profile of the formula based on the raw plant materials by using High-Performance Thin Layer Chromatography (HPTLC). In vitro, the antibacterial activity was conducted by agar disc diffusion and TLC-bioautography. The anti-inflammatory activity was conducted by nitric oxide (NO) production assay in RAW 264.7 macrophages which the inflammatory effect was induced by lipopolysaccharide (LPS).
Results
This study successfully explores the HPTLC method for analyzing the quality of YK raw materials. Whereas the pharmacological property of YK is examined. YK-lime juice extract exhibits the most effective antibacterial activity against both gram-positive and gram-negative bacteria. In addition, the methanolic extract of YK inhibited Streptococcus pyogenes and Klebsiella pnuemoniae by the TLC-bioautography method. Furthermore, YK extracts of methanol, water, and lime juice demonstrate significant anti-inflammatory properties, evidenced by a notable reduction in NO production in a macrophage model induced by LPS.
Conclusions
Overall, these pharmacological data could support the property of YK, a Thai Traditional medicine. It may be consumed to reduce inflammation and antibacterial co-infection not only for COVID-19 but also for other respiratory infections.
Classifications for Radiographic Evaluation of Radiolucent Bone Lesions have Poor Inter- and Intra-observer Agreement
Authors: Willenbring Taylor J. , Papa Sarah M. , Mann Kenneth A. , Cavallaro Salvatore , Damron Timothy A. 
Published: July 2024

Abstract

Background
Radiolucent bone lesions are encountered in all orthopedic specialties, and concise description is essential to inform evaluation and treatment. We studied the interobserver reliability and intra-observer reproducibility of three classification systems of radiographic radiolucent lesions: (1) original Lodwick classification, (2) modified Lodwick classification, and (3) Enneking classification for benign tumors. We hypothesized that intra-observer reproducibility would be good but interobserver reliability would be poor, improving with training level, and highest for the Enneking classification.
Methods
Forty-eight case sets of de-identified radiographs of radiolucent osseous lesions were selected from an orthopedic oncology practice. Each set included two orthogonal views of the lesion from initial presentation. Twenty participants (one third-year medical student, 18 residents, one orthopedic oncologist) classified each case twice, with a minimum two-week gap between sessions, according to the Lodwick classification, modified Lodwick classification, and Enneking classification. Interobserver reliability and intra-observer reproducibility were calculated using Fleiss’ kappa and Krippendorff’s alpha, treating the classifications as nominal and ordinal rankings, respectively. Linear regression models were used to determine the effect of training level on reproducibility. Contingency tables were used to assess the accuracy of correctly identifying benign versus malignant lesions against their known diagnoses.
Results
Interobserver reliability was poor, as demonstrated by agreement of 39% (κ = 0.23; α = 0.54), 39% (κ = 0.25; α = 0.48), and 53% (κ = 0.28; α = 0.45) for the Lodwick, modified Lodwick, and Enneking classifications, respectively. Intra-observer reproducibility also lacked strong agreement (κ = 0.42–0.45). Training level had no effect on reproducibility (R2 < 0.2, p > 0.05 for all classifications). Comparison of intra-observer reproducibility showed Krippendorff’s alpha for the Lodwick (α = 0.72), modified Lodwick (α = 0.69), and Enneking classification (α = 0.63). Self-agreement for individuals ranged from 39–78%. Lesions were correctly classified as malignant for 73.3%, 59.0%, and 62% of cases for the three classification systems, respectively.
Conclusions
Our data demonstrate that three common classifications for osseous radiolucent lesions are neither reliable nor reproducible. Consistency of classification varied depending on lesion characteristics, with the strongest reproducibility demonstrated for the highest and lowest grades of the classification systems. There was no association between orthopedic experience and intra-observer reproducibility. These deficiencies may be improved with AI applications.
Effect of different corrective force directions applied by spinal orthoses on the patients with adolescent idiopathic scoliosis

Published: July 2024

Abstract

Background
Spinal orthoses are commonly prescribed for moderate adolescent idiopathic scoliosis (AIS), however, their effect on three-dimensional correction is not fully investigated. Moreover, the amount of deformity control largely depends on the corrective forces applied via the orthoses, which remains empirically based due to lack of consensus on optimal force application. This study investigated the effects of different corrective force directions exerted by spinal orthoses on the patients with AIS.
Methods
A retrospective analysis was conducted on 69 subjects. The trunk was segmented into four quadrants using coronal and sagittal planes from a top-down perspective. Each of the left or right posterolateral quadrant (with 90°) was equally subdivided into zones 1–4 from the sagittal to coronal planes. Based on the zone where the resultant corrective force direction fell, the subjects were categorized into Group 1 (zone 1), Group 2 (zone 2), Group 3 (zone 3), or Group 4 (zone 4). The direction of the corrective force was estimated using the modified models of the subjects’ bodies, designed through the computer-aided design and manufacturing system integral to the orthosis fabrication process. The effects of corrective forces in different zones on scoliotic spine were assessed.
Results
Of the subjects, 17 were in Group 2 and 52 in Group 3, with no subjects meeting the criteria for Groups 1 and 4. Both Groups 2 and 3 showed significant reductions of Cobb angle in the coronal plane and plane of maximum curvature (PMC) following orthosis fitting (p < 0.05). Group 2 displayed a significant decrease > 5º in thoracic kyphosis (p < 0.05), and a more pronounced reduction > 10º in lumbar lordosis compared to Group 3. PMC orientation remained unchanged over time (p > 0.05) but was notably higher in Group 2 after orthosis fitting (p < 0.05).
Conclusions
Corrective forces, applied by spinal orthoses, in zones 2 and 3 could effectively control the lateral curvature. However, only those in zone 3 did not reduce thoracic kyphosis and did not worsen the deviation of the scoliotic spine from the sagittal plane. Further research is needed to confirm and extend these results.
