Los atributos de los establecimientos educacionales que pueden predecir la preferencia por parte de los apoderados

La presente investigación indaga acerca de cómo se comportó la matrícula con el Sistema de Admisión Escolar (SAE) para el proceso 2020, aplicado por primera vez en todas regiones de Chile. Con ello se busca medir la relación estadística entre ciertos atributos de los establecimientos educacionales, con la cantidad de preferencias que tienen por parte de los apoderados de prekínder, kínder y primero básico. A través de la aplicación de un modelo de regresión lineal múltiple, el conjunto de variables independientes considerados en este estudio explica un tercio de la variabilidad de la demanda que atraen los colegios. El resultado que tienen las escuelas en pruebas estandarizadas (SIMCE) y la proporción de matrícula de estudiantes vulnerables (IVE) se revelan como las principales variables predictoras.Este estudio busca aportar al debate teórico respecto del fenómeno de elección de establecimiento educacional en Chile y, al mismo tiempo, introducir al SAE y a los datos que genera como fuente de información en el campo de la investigación en educación, lo cual puede ser clave para planificar cómo fortalecer el sistema educativo y entregar una oferta más equilibrada a los(as) estudiantes
Current Distribution Measurements in Parallel-Connected Lithium-Ion Cylindrical Cells under Non-Uniform Temperature Conditions

Understanding internal state non-uniformity that occurs across the electrodes in large-format Lithium-ion batteries, and among parallel-connected cells, is a critical part of the cell and battery module design process. Two separate groups of parallel-connected 18650 cells were tested using LiFePO4/C6 (LFP), and LiNiMnCoO2/C6 (NMC) chemistries. Pulse and full-capacity discharges were performed at various States of Charge (SOC), C-rates, average temperatures, and levels of temperature non-uniformity. Current nonuniformity for the pulse testing was always lower for the LFP group compared to the NMC group. The hottest cell in the LFP group produced up to 40% more current than average, while this was up to 80% for NMC. Conversely, under charge depleting conditions the NMC group experienced less current non-uniformity, and in certain cases provided a nearly uniform current distribution in the presence of non-uniform temperature. The results indicate that higher temperature sensitivity in the impedance of a cell will cause larger current non-uniformity under pulse conditions. However, due to the presence of non-uniform SOC for charge depleting, the Open Circuit Voltage (OCV) versus SOC gradient plays a significant role in dictating the current distribution behavior, where steeper OCVs provide a corrective action that minimizes the effect of the non-uniform impedance. © The Author(s) 2017.

Skin Antiaging Effects of the Fermented Outer Layers of Leaf Skin of Aloe barbadensis Miller Associated with the Enhancement of Mitochondrial Activities of UVb-Irradiated Human Skin Fibroblasts

This study is the first to show that increased mitochondrial activities improved the antiaging effects of Aloe vera leaf skin fermented by Lactobacillus plantarum on UVb-irradiated skin fibroblasts. The fermented extract (AF) increased the activities of mitochondrial reductase and the complex II and significantly reduced reactive oxygen species (ROS) production, even under UVb stress conditions, and also increased DPPH free radical scavenging activities compared with the hot water extract of outer layers of aloe leaf (AW) and quercetin itself. AF exerted a synergistic effect with quercetin and bioactive substances derived from the fermentation process. Moreover, mitochondrial activation of UVb-irradiated human skin fibroblasts by 0.3% (w/v) of the AF plays important roles in increasing collagen production up to 125 ± 5.45% and decreasing MMP-1 secretion down to 69.41 ± 2.63% of the control levels. The AF enhanced the upregulation of collagen gene expression, and this change was also greater than those induced by the AW and quercetin. Therefore, this study concludes that fermentation of the skin of aloe leaves increases the activation of mitochondria and inhibits the photo-aging of UVb-irradiated skin fibroblasts.
A Time‐Resolved Paleomagnetic Record of Main Group Pallasites: Evidence for a Large‐Cored, Thin‐Mantled Parent Body

Several paleomagnetic studies have been conducted on five Main Group pallasites: Brenham, Marjalahti, Springwater, Imilac, and Esquel. These pallasites have distinct cooling histories, meaning that their paleomagnetic records may have been acquired at different times during the thermal evolution of their parent body. Here, we compile new and existing data to present the most complete time‐resolved paleomagnetic record for a planetesimal, which includes a period of quiescence prior to core solidification as well as dynamo activity generated by compositional convection during core solidification. We present new paleomagnetic data for the Springwater pallasite, which constrains the timing of core solidification. Our results suggest that in order to generate the observed strong paleointensities (∼65–95 μT), the pallasites must have been relatively close to the dynamo source. Our thermal and dynamo models predict that the Main Group pallasites originate from a planetesimal with a large core (>200 km) and a thin mantle (<70 km).
THE IMPACT OF CLOSURE DEVICES ON VASCULAR COMPLICATIONS DURING TRANSCATHETER AORTIC VALVE IMPLANTATION PROCEDURES IN GERIATRIC PATIENTS

Introduction : In transcatheter aortic valve implantation, some closure devices can be used as an alternative to the surgical exploration of the femoral artery for vascular access. This study aimed to compare closure devices and surgical exploration techniques in terms of vascular access complications, particularly in geriatric patients. Materials and Methods : This study included 169 patients who had undergone transcatheter aortic valve implantation at a cardiology clinic between August 2014 and January 2019. The patients’ mean age was 76.62 years; 53.30% were male. The preferred access site was the femoral artery in all the patients. Patients in whom a closure device was used were included in the Prostar and ProGlide groups, and those who underwent surgical exploration of the femoral artery were included in the Surgery group. The endpoints of the study were postoperative bleeding, infection, and a recurring need for surgical repair. Results : Of the patients, 55.60%, 29.60%
Electrochemistry, Electrodeposition, and Photoluminescence of Eu (III)/Lanthanides (III) on Terpyridine-Functionalized Ti Nanospikes

Terpyridine-functionalized Ti nanospike electrodes (TiNS-SiTpy) were developed and applied to cyclic voltammetry and amperometry of Ln (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb) ions and mixed Eu (III) + Ln (III) ions in a 0.1 M NaClO4 electrolyte. Electrodeposition was successfully performed over TiNS-SiTpy electrodes, which were fully examined by scanning electron microscopy, X-ray diffraction crystallography, Fourier-transform infrared spectroscopy, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, photoluminescence (PL), and PL decay kinetics. The Gd and Tb ions were found to increase PL intensities with 10× longer lifetimes of 1.32 μs and 1.03 μs, respectively, compared with that of the electrodeposited Eu sample. The crystal phase and the oxidation states were fully examined for the mixed Ln (Eu + Gd and Eu + Tb) complex structures.
Non-obvious effects of montelukast – leukotriene receptor blocker: frigoprotective and anticonvulsant properties

The participation of arachidonic acid metabolism products – prostaglandins and leukotrienes – in the process of inflammation is a common pathogenetic link of cold injury and epilepsy. Montelukast is widely used for the treatment of bronchial asthma and allergic rhinitis as a leukotriene receptor blocker. However, the mechanism of action of the drug suggests a wider range of its pharmacological properties and the corresponding scope of application. This study is aimed to determine the effectiveness of montelukast as a potential frigoprotective and anticonvulsant drug. Experiments were performed on 73 white mice weighing 20-22 g on models of acute general cooling and pentylenetetrazol convulsions. Frigoprotective properties were studied at a temperature of –18°C, recording the lifetime. Montelukast ("Singular", 2 mg/kg), acetylsalicylic acid ("Aspirin", 50 mg/kg), celecoxib ("Celebrex", 74 mg/kg), diclofenac sodium ("Voltaren", 14 mg/kg) were administered intragastrically as a suspension in a prophylactic mode, 30 minutes before the cold injury. In the study of anti­convulsant activity, montelukast ("Singular", 4 mg/kg) and sodium valproate ("Depakin", 300 mg/kg) were admi­nistered intragastrically 30 minutes before stimulating convulsions by subcutaneous administration of pentylene­tetrazole (90 mg/kg). The latent period of convulsions, the number of convulsions per 1 animal, % of mice with clonic and tonic paroxysms, the severity of convulsions in points, the duration of the convulsive period, the lifetime of animals and lethality were recorded for an hour. On the model of acute general cooling, montelukast showed a dose-dependent frigoprotective effect at a dose of 2 mg/kg surpassing drugs with proven frigoprotective properties – acetylsalicylic acid and celecoxib. On the model of pentylenetetrazole-induced convulsions, montelukast statistically significantly reduced the integral indicator of anticonvulsant activity – lethality – by 2.57 times. Thus, the experiment proved the significant role of leukotrienes in the pathogenesis of cold injury and epilepsy and justified the feasibility of further study of the frigoprotective and anticonvulsant properties of montelukast – leukotriene receptor blocker a drug as for adjuvant therapy, especially when these pathologies are combined with bronchial asthma and allergic rhinitis.
Concomitant functional impairment and reorganization in the linkage between the cerebellum and default mode network in patients with type 2 diabetes mellitus.

Background Increasing evidence shows that the default mode network (DMN) and cerebellum are prone to structural and functional abnormalities in patients with type 2 diabetes mellitus (T2DM). However, the type of change in the functional connection between the DMN and cerebellum is still unknown. Methods In this study, seed-based functional connectivity (FC) analysis was used to examine the intrinsic FC of the cerebellum-DMN between healthy controls (HCs) and T2DM patients. Pearson correlation analysis was used to explore the relationship between clinical variables and changes in FC. Results Compared with HCs, T2DM patients showed significantly increased FC of the left crus I-left medial superior frontal gyrus, left crus I-right medial superior frontal gyrus, and right crus I-left medial orbitofrontal cortex. Compared with HCs, T2DM patients showed decreased FC of the lobule IX-the right angular gyrus. Moreover, diabetes duration was positively correlated with increased FC of the left crus I-right medial superior frontal gyrus (r=0.438, P=0.007). Conclusions Concomitant functional impairment and reorganization in the linkage between the cerebellum and DMN in patients with T2DM may be a biomarker of early brain damage that can help us better understand the pathogenesis of cognitive impairment in T2DM.
Does a carbon emissions trading scheme spur urban green innovation? Evidence from a quasi-natural experiment in China

Based on the panel data of 277 cities between 2003 and 2017 and a unique city-level dataset of green patent applications, this study employs the difference-in-differences (DID) method to evaluate the effect of China’s carbon emission trading scheme (ETS) pilots on urban green innovation. The findings indicate that China’s ETS pilots have a positive impact on urban green innovation, and that impact is more significant for municipalities than for prefecture-level cities. Furthermore, the impact on different categories of urban green innovation is heterogeneous. More specifically, China’s ETS pilots have significantly spurred urban green innovation that is closely related to energy conservation and emission reduction, including alternative energy production, transportation, energy conservation and so forth. Moreover, the facilitating effect of China’s ETS pilots on urban green innovation suffers from a lagging effect, which began to show a significant positive effect in 2016. Overall, this paper identifies the effect of China’s ETS pilots on urban green innovation, and suggests that the government should consider the heterogeneity of urban green innovation when designing national ETS policies.
System Performance Optimization for Dual-Loop Dual-Variable Controlled Active Clamp Flyback Converter Using Decoupling Compensation Technique

Active clamp flyback (ACF) is a good candidate to be used in high frequency power adapter applications. For high performance, dual-loop dual-variable (DLDV) control strategy consists of voltage, current and period regulation loops is very suitable to be used in ACF converter. However, the complexed control framework makes the controller is hard to design, and which can affect the dynamic response of the system. Therefore, a cascade controller consists of a decoupling controller and digital controller is proposed for good stability and dynamic characteristic. The decoupling controller is used to eliminate the coupling effect between the output voltage and period regulation loop, and the digital controller is adopted to stabilize the system. To verify the effectiveness of the designed controller, simulation and experimental results based on a 65W 19.5V output ACF prototype are tested. By comparing with the non-decoupling controller, the designed controller has a faster dynamic and smaller voltage overshoot and undershoot in DLDV controlled ACF converter.
Beneficial effects of polyphenols in metabolic syndrome—a review

INTRODUCTION: Polyphenols (PPs) are plant-derived chemical compounds bearing one or more phenolic rings. The most commonly presented dietary PPs include anthocyanins, flavonols, flavanols and phenolic acids. Studies have shown that polyphenols exert a variety of actions including antioxidant, anti-inflammatory, antimicrobial, antiproliferative, cancer protective, cardioprotective, lipid-lowering, and glucose-lowering. Metabolic syndrome (MetS) is a global health issue associated with an increased risk of cardiovascular diseases, type 2 diabetes, and certain types of cancer. AIM: The purpose of this paper is to summarize the current knowledge about the beneficial effects of different polyphenols on the clinical manifestations of metabolic syndrome. MATERIALS AND METHODS: Literature in PubMed, Google Scholar and ScienceDirect has been studied and analyzed. RESULTS: Most data about the beneficial effects of polyphenols is derived from preclinical studies. The clinical trials involving polyphenolic compounds in subjects with MetS are limited, comprise a small number of participants, and the duration is short. CONCLUSION: Numerous studies show promising effects of polyphenols in improving the biochemical and clinical abnormalities associated with metabolic syndrome but larger, more precise, better controlled clinical trials are necessary to reveal their benefits in clinical practice.
The Effect of Zinc Oxide Scallop-Shell Powder and Complications After Coronary Angiography

Introduction: Coronary angiography is often associated with complications such as hemorrhage and hematoma that should be considered and be minimized. Objective: This study aimed to determine the effect of Zinc oxide scallop-shell powder as a topical hemostatic agent (composed mainly of calcium) on complications after coronary angiography. These complications include hemostasis time, low back pain, hemorrhage, hematoma, the necessity of sandbags, and patient ambulation. Materials and Methods: The current research was a blind, parallel, randomized clinical trial done on 150 patients under coronary angiography. They were randomly divided into three equal groups of A (control), B (case 1), and C (case 2). In group A, hemostasis was done with manual compression, use of ChitoHem powder, putting sandbag for 4-6 h in a supine position, and getting out of bed after 24 h. In group B, instead of ChitoHem powder, we used Zinc oxide scallop-shell powder. In group C, hemostasis was done with manual compression, Zinc oxide scallop-shell powder, putting sandbag for 1 h in a supine position, and getting out of bed after 2 h. The duration of hemostasis, bleeding, and hematoma after hemostasis and the severity of low back pain were investigated at 8 point intervals during 24 h. Data analysis was done using descriptive statistics indicators and Kolmogorov-Smirnov, ANOVA, Chi Square, Fisher exact test and Kruskal-Wallis tests. Results: The mean ±SD ages of groups of A, B, and C were 60.08 ±11.32, 60.22 ±10.30, and 61.69 (10.61), respectively, which was not statistically different. Furthermore, there was no significant difference between these three groups regarding their demographic information. There were statistically significant differences between groups about the amount of low back pain at the second, third, and fourth hours after angiography (P= 0.001). There was a significant difference in the amount of bleeding between the three groups (P=0.017). The difference in time of hemostasis in the three groups was not statistically significant. Conclusion: The Zinc oxide scallop-shell powder reduces catheter site bleeding after coronary angiography and bed rest time and ultimately the severity of low back pain. Performing a similar study is recommended.
Current Evidence for Nutrition Intervention: A Meta-analysis

Although different combinations of nutrition interventions are employed, most are insufficient to reduce stunting significantly. This study aimed to draw current evidence to reduce stunting among under 5 years children from randomized controlled trials. Eligible randomized controlled trials met inclusion criteria were included. The weighted mean effect sizes with 95% CIs were used as summary measures for changes in height-for-age z score (HAZ) using random-effect models; heterogeneity was analyzed using predefined characteristics. From the total of 116 articles, 47 randomized controlled trials with a sample size of 35,115 study participants were included for analysis. Except for educational intervention (0.14; 95%CI: 0.00, 0.27), the weighted mean effects of iron, zinc, water, sanitation and hygiene (WASH), multiple micronutrients (MMN) and dietary interventions were all insignificant. A ﬁxed combination of nutrition interventions demonstrating similar beneﬁt in all contexts is not found. Our results are insufficient to make a recommendation on the most appropriate interventions to reduce stunting in all settings. This result highlights the importance of further evidence before nutrition component formulation for large-scale interventions. The short duration of the interventions and lack of information about the infection status of participants in most of the included trials remain two of the possible limitations needing consideration.
RADIATION IN A PALLIATIVE SETTING DURING COVID-19 ERA. AN INDIAN TERTIARY CANCER CARE PROSPECTIVE – RISKS, BENEFITS .

India and the rest of the world are experiencing an outbreak of the COVID- 19 virus. WHO has declared 2019 novel coronavirus disease (COVID19), a public health emergency of international concern. (1) Palliative treatment compromises a major portion of radiation treatments in cancer. (2) Metastatic or palliation treatment presents a unique challenge in resource-limited settings as ours and early treatment to alleviate their symptoms and disease is the need of the hour to prevent further morbidity and mortality. These patients are usually more cachexic with low immunity and more prone to infection of COVID-19 than the normal population, here their treatment has to be expedited and their visits to the hospital to be minimized to prevent infection with COVID. (3) We reviewed the best evidence and recommended best practices for the treatment of common oncologic emergencies with more emphasis on balancing the risk of infection with the COVID-19 virus and the potential morbidity of delaying treatment. In COVID -19 Era pandemic, the use of hypofractionated radiation therapy for palliative patients for oncologic emergencies achieves intended functional outcomes without compromising care
An Exploratory Analysis of Museum Attributes from the Perspective of Tourists and Residents: The Case of Thyssen-Bornemisza National Museum, Madrid, Spain

Attribute evaluation provides an understanding of the perceived quality and subjective value of the museum visitor experience. The principal contribution of this paper is to analyze the attributes perceived by tourists and the local community (Madrid residents) of the Thyssen-Bornemisza National Museum (Madrid, Spain), utilizing the results from choice experiment and willingness-to-pay questionnaires. To analyze in depth the assessment regarding the museum attributes and the visitor perceptions of them, the relevance-determination model was applied. Data collection was achieved with a questionnaire using a convenience sample of international tourists and the local community, providing a total of 775 valid surveys. The results of the application of the relevance-determination analysis (RDA) show that there are two types of attributes: higher-impact core and lower-importance attributes. The attributes with the highest subjective value perceived by interviewed tourists and interviewed residents are the location, the building, and the permanent collection. These results show that there are substantial differences between the perception and appreciation of these attributes by interviewed residents and interviewed tourists. The results provide valuable information that can be applied in practice to devise strategies for economic and socio-cultural sustainability aimed at improving decision-making in museum management.
Separation of Data Cleansing Concept from EDA

Available dataset whether it is structured, semi structured or unstructured data, is used for various purposes. These data sets are mostly used for solving an issue using different kinds of techniques like visualization, descriptive, algorithms etc. This data process includes many levels, two of those steps are exploratory data analysis (EDA) and data cleansing. Data cleansing and exploratory data analysis (EDA) are two major operations of any data mining or machine learning study. After collecting the data from various sources, Data cleansing is done to make the data set more accurate, useful and less redundant. Data cleansing is useful to get the accurate information from the dataset and It is used to deal with null values, duplicate values, multiple values, inconsistent value, inaccurate value etc, Which are existing in that data set and It can make our data set filled with error which also affects the analysis and decision making process. By performing data cleansing, we can get rid of many types of misleadings like getting inaccurate output, inaccurate model of machine learning, not getting the hidden patterns behind that data set etc. The purpose of this paper is to study existing research of Data cleansing and EDA and state why Data cleansing process is not part of exploratory data analysis (EDA).
