Published: January 2023

The aim of this study is to assess the individual gamma-ray transmission factors (TFs) and some fundamental gamma-ray attenuation properties of several types of glasses based on WO3–TeO2–B2O3 glasses system. MCNPX (version 2.7.0) is used for the calculation of TFs. Other critical parameters are determined using the Phy-X/PSD program. To determine the TFs of studied glasses, several medical radioisotopes are determined along with their characteristic gamma-ray energies. The superior values for the investigated parameters are found in glass sample S6. Furthermore, the exposure build-up factor and energy absorption build-up factor values for glass sample S6 were the lowest. S6 glass sample with the chemical composition 0.03833B + 0.26075O + 0.11591Zn + 0.52783Te + 0.05718W and a density of 3.3579 g/cm3 is found to have exceptional gamma-ray attenuation qualities, according to our findings. It can be concluded that the prospective attributes of WO3-doped glass systems and associated glass compositions would be beneficial for scientific community in terms of providing a clearer view for some advanced applications of these glass types.

Published: January 2023

We report some fundamental gamma-ray shielding properties and individual transmission factors (TFs) of five distinct glass samples with a nominal composition of xSb2O3·(40 − x)PbO·60B2O3·0.5CuO and (where; 0 ≤ x ≤ 40 mol%). Phy-X/PSD and MCNPX (version 2.7.0) Monte Carlo code are utilized to determine several critical parameters, such as cross-sections, attenuation coefficients, half and tenth value layers, build-up factors, and TFs. A general transmission setup is designed using basic requirements. Accordingly, TFs are evaluated for several medical radioisotopes. Next, the gamma-ray shielding parameters and TFs are assessed together in terms of providing the validity of the findings. Our results showed that there is a positive contribution of increasing Sb2O3 amount in the glass matrix owing its direct effect to the density increment as well. This positive effect on gamma-ray shielding properties is also observed for decreasing mean free path values from S1 to S5 samples. The exposure build-up factor (EBF) and energy absorption build-up factor (EABF) values, increasing the quantity of Sb2O3 supplementation, resulted in a general reduction in EBF and EABF values (i.e., from 0.5 to 40 mfp). When the quantity of Sb2O3 rises from S1 to S5, the collision rate of incoming gamma rays in glass samples increases significantly. The TF figures reveal that S5 showed the least transmission behavior across all the above-mentioned studied glass thicknesses. It can be concluded that increasing the Sb2O3 additive is a beneficial and monotonic technique, when the gamma-ray shielding qualities or TF values must be further enhanced.

Published: January 2023

Landslides are frequent geological hazards, mainly in the rainy season along road corridors worldwide. In the present study, we have comparatively analyzed landslide susceptibility by employing integrated geospatial approaches, i.e., data-driven, knowledge-driven, and machine learning (ML), along the main road corridors of the Muzaffarabad district. The landslide inventory of three road corridors is developed to evaluate landslide susceptibility, and eleven landslide causative factors (LCFs) were analyzed. After statistical significance analysis, these eleven LCFs generated susceptibility models using WoE, AHP, LR, and RF. Distance from roads, landcover, lithological units, and slopes are considered more influential LCFs. The performance matrix of different LSMs is evaluated through the area under the curve (AUC-ROC), overall accuracy, Kappa index, F1 score, Mean Absolute Error, and Root Mean Square Error. The AUC-ROC for WoE, AHP, LR, and RF techniques along Neelum road is 0.86, 0.82, 0.91, and 0.97, respectively, along Jhelum Valley road is 0.83, 0.81, 0.93, and 0.95, respectively, while along Kohala road is 0.89, 0.88, 0.89, and 0.92, respectively. The produced LSMs through ML (i.e., RF and LR) showed better prediction accuracies than WoE and AHP along these three road corridors. The LSMs are categorized into very high, high, moderate, and low susceptible zones along these roads. The LSM generated through hybrid models can facilitate the concerned local agencies to implement landslide mitigation policies for the landslide-prone zones along road corridors.
Agriculture and aquaculture land-use change prediction in five central coastal provinces of Vietnam using ANN, SVR, and SARIMA models
Authors: Wang YuRen , Giang Nguyen Hong
Published: January 2023

Vietnam’s economy with agriculture and aquaculture still account for roughly 26% of the country’s gross domestic product, and nearly 70% of the Vietnamese population lives in rural areas; therefore, agriculture and aquaculture land use play a crucial role in the development process of Vietnam. Rapidly increasing population and infrastructure in rural areas and industrial zones lead to these land-use changes. Hence, these land-use change predictions are crucial for local authorities and the local people to make land-resource funds and set up planning. This article suggests support vector regression (SVR), artificial neural network (ANN), and seasonal autoregressive integrated moving average (SARIMA) methods to predict land-use change. By comparing the three models, the results indicate that almost all of the SVR models improve the accurate performance more than ANN and SARIMA in Quangtri, ThuThienHue, Danang, and Quảngnam provinces. Furthermore, the ANN model indicates more accurate forecasting than the SVR and SARIMA models in Quan Binh province. The result may be support for the Ministry of Natural Resources and Environment to conduct the land-use inventory and upgrade agriculture and aquaculture land-use change maps every 5 years. Afterward, the Department of Natural Resources and Environment’s provinces use the estimating database and update it manually.

Published: January 2023

Objectives

There is evidence that mitochondrial dysfunction mediated by hyperglycemia increases the incidence of diabetes and age-related insulin resistance. Thus, maintaining mitochondrial integrity may provide alternative therapeutic approach in diabetes treatment. This study aimed to evaluate the effect of Bambusa vulgaris leaf extract on mitochondrial biogenesis in the pancreas of diabetic rats.

Methods

11 weeks old male rats (n=30) were purchased, and sorted into the following groups: control, diabetic control, diabetes + metformin (100 mg/kg), diabetes + Aq. B. vulgaris (100 mg/kg), diabetes + Aq. B. vulgaris (200 mg/kg), and diabetes + Aq. B. vulgaris (300 mg/kg). Diabetes was induced in the rats by a single dose of 65 mg/kg streptozotocin (STZ). The mRNA expression of genes related to mitochondria biogenesis (pgc-1α, Nrf2, GSK3β, AMPK and SIRT2) and genes of Nrf2-Keap1-ARE signaling pathway were determined by reverse transcriptase polymerase chain reaction. Molecular docking studies including lock and key docking and prime MM-GBSA were incorporated to identify the lead chemical compounds in Bambusa vulgari.

Results

The results showed that B. vulgaris leaf extract promotes mitochondrial biogenesis via altering the mRNA expression of mitochondrial master regulator pgc-1α, other upstream genes, and the Nrf2-Keap1-ARE antioxidant pathway. Through molecular docking results, cryptochlorogenic acid, hesperidin, orientin, vitexin, scopolin, and neochlorogenic were found as the crucial chemicals in B. vulgaris with the most modulating effect on PGC-1α, AMPK, and GSK3.

Conclusions

This study thus suggests that B. vulgaris leaf extract restores the integrity of mitochondria in diabetic rats.
Elevated amylase and lipase levels in patients with DKA followed in the pediatric intensive care unit
Authors: Atakul Gulhan , Demiral Meliha , Gürer Güliz
Published: January 2023

Objectives

Diabetic ketoacidosis (DKA) is a life-threatening acute metabolic decompensation condition due to insulin deficiency and elevation of pancreatic enzymes is common. The goal of this study was to determine the laboratory findings and biochemical characteristics associated with pancreatic enzyme elevation during DKA.

Methods

The files of patients hospitalized in the pediatric intensive care unit with the diagnosis of DKA between March 2020 and 2022 were reviewed retrospectively. Demographic data, length of stay at hospital, initial biochemistry, hemogram, blood gas values, amylase, and lipase in the first 24 h were noted. Those with elevated amylase and/or lipase values were grouped. Patients were grouped according to the severity of DKA. These groups were analyzed statistically.

Results

Amylase and/or lipase were found to be elevated in 21 (28%) of diagnosed with DKA. pH and HCO3 were significantly lower, length of stay in the intensive care unit, and triglyceride levels were significantly higher in patients with high amylase and/or lipase when compared with the control group (p<0.05). Although lipase values have a negative correlation with blood gas parameters and a positive correlation with TG and cholesterol values, correlation degree was found to be weak (p<0.05). Lipase was significantly higher in the severe diabetic ketoacidosis group than the moderate group (p<0.001).

Conclusions

Elevations in amylase and lipase values can be encountered frequently in patients with DKA. Considering that the metabolic deterioration due to DKA may have an effect on this, we recommend that the patient should be followed closely and the enzyme level should be monitored intermittently.

Nanogap enhancement of the refractometric sensitivity at quasi-bound states in the continuum in all-dielectric metasurfaces
Authors: Watanabe Keisuke , Iwanaga Masanobu
Published: January 2023

All-dielectric metasurfaces have great potential as highly sensitive refractometric sensors relying on their spectral shifts because of an extensive range of design flexibilities and their smaller absorption losses than plasmonic platforms. However, simultaneously realizing both high quality (Q) factors and the large interplay of light with external medium in such photonic sensors remains one of the key challenges for their better performance. This study proposes silicon block metasurfaces with nanogaps to overcome this challenge based on quasi-bound states in the continuum (BICs). We show that the metasurface has two quasi-BIC modes—magnetic dipole (MD) and electric quadrupole (EQ)—and their electric fields experience large enhancement at the ∼30 nm nanogap regions. Consequently, introducing nanogaps into the metasurfaces increases the environmental refractive index sensitivity by up to 2.7 times in the MD mode while keeping the high Q factors and achieves the figure-of-merit (FOM) of 239. In addition, we show that the appropriate selection of the amount of asymmetry is needed under the trade-off between the FOM and spectral signal-to-noise ratio, which provides design guidelines for highly sensitive biosensors based on quasi-BICs.
Study on the preparation process and sintering performance of doped nano-silver paste
Authors: Yang Hui
Published: January 2023

After tin–lead solders are banned, the widely used electronic packaging interconnect materials are tin–silver, tin–copper, and other alloy solders. With the application of high-power devices, traditional solders can no longer meet the new requirements. Nano-silver (Ag) paste, as a new solder substitute, exhibits excellent properties, such as excellent thermal and electrical conductivity, sintering at lower temperatures, and service at high temperatures. However, many organic devices still cannot withstand this temperature, and are often not suitable for the connection of nano-Ag paste packaging materials, therefore, it is very urgent to further reduce the sintering temperature of nano-silver paste. Based on the transient liquid phase sintering technology, by doping the nano-Ag paste with the nano-tin paste with a lower melting point to make the two uniformly mix, pressureless sintering at low temperature can be realized, and a sintered joint with a connection strength greater than 20 MPa can be formed. Considering that tin is easy to be oxidized, and the core–shell material can prevent the oxidation of tin, and at the same time ensure the uniform distribution of tin in silver, the doping scheme of the core–shell structure is determined. Heterogeneous flocculation method refers to the particles with different properties of charges which attract each other and agglomerate. It is a continuous reduction method for preparing core–shell materials. This method has the advantages of mild reaction conditions and less equipment investment, so the heterogeneous flocculation method is selected to prepare Sn@Ag core–shell nano paste. And research its sintering performance and strengthening mechanism.

Legionella‐ and host‐driven lipid flux at LCV‐ER membrane contact sites promotes vacuole remodeling

Published: January 2023

Legionella pneumophila replicates in macrophages and amoeba within a unique compartment, the Legionella‐containing vacuole (LCV). Hallmarks of LCV formation are the phosphoinositide lipid conversion from PtdIns(3)P to PtdIns(4)P, fusion with ER‐derived vesicles and a tight association with the ER. Proteomics of purified LCVs indicate the presence of membrane contact sites (MCS) proteins possibly implicated in lipid exchange. Using dually fluorescence‐labeled Dictyostelium discoideum amoeba, we reveal that VAMP‐associated protein (Vap) and the PtdIns(4)P 4‐phosphatase Sac1 localize to the ER, and Vap also localizes to the LCV membrane. Furthermore, Vap as well as Sac1 promote intracellular replication of L. pneumophila and LCV remodeling. Oxysterol binding proteins (OSBPs) preferentially localize to the ER (OSBP8) or the LCV membrane (OSBP11), respectively, and restrict (OSBP8) or promote (OSBP11) bacterial replication and LCV expansion. The sterol probes GFP‐D4H* and filipin indicate that sterols are rapidly depleted from LCVs, while PtdIns(4)P accumulates. In addition to Sac1, the PtdIns(4)P‐subverting L. pneumophila effector proteins LepB and SidC also support LCV remodeling. Taken together, the Legionella‐ and host cell‐driven PtdIns(4)P gradient at LCV‐ER MCSs promotes Vap‐, OSBP‐ and Sac1‐dependent pathogen vacuole maturation.
La narrazione umoristica di Federico Seismit-Doda
Authors: Jusup Magazin Andrijana
Published: January 2023

Nel 1846 Federico Seismit-Doda (Ragusa, 1825 – Roma, 1893), politico e patriota italiano, originario della Dalmazia, pubblica sul giornale letterario veneto Il Gondoliere il testo Studi drammatici. Ore di un condannato… alla scena a due puntate in due numeri consecutivi. Nel suo contributo Seismit-Doda narra la (s)fortuna di un certo Luigi Ruffoli, autore drammatico che, tre anni dopo un esordio teatrale di successo, mette in scena una commedia che alla fine venne fischiata. Oltre all’analisi delle numerose coincidenze biografiche fra autore e protagonista, che permettono di definire l’intera narrazione come autobiografica, nel presente studio è stata approfondita la peculiarità della strategia narrativa umoristica del modello sterniano. L’autore ricorre a procedimenti narrativi e retorici che fanno scattare i meccanismi dell’umorismo, quali digressioni metanarrative, interruzioni, parodia dei linguaggi e dei codici. In tal modo si conferma capace di ricreare tutti gli effetti dello stile umoristico. D’altronde, prendendo in considerazione un contesto più vasto del filone narrativo italiano di carattere umoristico, la sperimentazione narrativa nel testo Ultime ore di un condannato… alla scena vale a riprova che Federico Seismit-Doda era propenso a ricorrere alle modalità tipiche della scrittura umoristica dell’Ottocento italiano.
(I)reverzibilnost leksičkih binoma u talijanskome i hrvatskome jeziku

Published: January 2023

Stabilnost strukture važno je frazemsko obilježje, koje se na početku razvoja frazeologije kao znanstvene discipline jasno ograničilo i istaknulo. Međutim, istraživanja temeljena na analizi mrežnih korpusa pokazuju da pojedina obilježja zahtijevaju drugačiji pristup. Stabilnost strukture ne isključuje se iz popisa temeljnih obilježja frazema, ali se sve više smatra relativnom, dok se varijabilnost frazema naglašava kao značajka koja također bitno obilježava frazeme. To vrijedi za sve frazeološke podvrste uključujući i leksičke binome. Različiti tipovi varijacije obilježavaju i same binome, ali o njihovoj reverzibilnosti, odnosno topološkoj varijaciji nisu postojala opsežnija istraživanja. Unatoč manjkavosti frazeografske obradbe leksičkih binoma, mnogi od njih pokazuju visok postotak reverzibilnosti. Raščlambom se ekscerpiranih primjera iz korpusa talijanskoga i hrvatskoga jezika reverzibilnost potvrđuje kao bitno obilježje leksičkih binoma.
Youth Out of Touch? Early Assessment of Millennial Leaders’ Performance on Human Capital Development at Indonesian Districts
Authors: Sardini Nur Hidayat , Wiryawan Bangkit Aditya , Martini Rina
Published: January 2023

Starting in the second round of local election, participation of millenials has been increasing. The term refers to the young demographic cohort born between 1980 and 2002, known to have distinct characteristics to the previous generations. We gathered seventeen cases of elected millennial district heads between 2010 and 2017 and making an early observation of their impact on human capital development. Simplified difference-in-difference estimation method is applied using province average as the control group. Results show that following the winning of the millennial leaders there is a diverging trend of Human Development Index score at 0.03 and 0.07 in the first and second year, consecutively, before started converging around the third and fourth year. Lacking leadership skills and experiences, that may also be perpetrated by generational gap, are among the contributing factors to the problem. We further find that leaders not affiliated with political dynasty fare better. We check the robustness of our result using poverty data and further find that millennial leaders are also under-perform in combating poverty. This early assessment would benefit from further heterogeneity analyses as well as narrowing the control group, which is our recommendation for future research.

Implementation Election Regent and Representative Regent Pekalongan It is the year 2020, which is one of the elections in Indonesia, which was held amid the Covid-19 Pandemic, experiencing enhanced political participation in society. Different from the most significant challenge during this implementation election common in the district of Pekalongan is the level of participation people tends to be low because of the condition of geography and topography different in the district Pekalongan. The results of this study conclude that first, with the high political participation of voters during the COVID-19 pandemic, the opportunity for people to come to the polling station is significant. However, the topography and geography of the region also have a significant influence because each region provides equal opportunities for voters to come to the polling station. Second, implementing the 2020 Pekalongan Regent and Deputy Regent Elections can be carried out safely and adequately with high voter political participation. High voter political participation was achieved by 77.75% and exceeded the national target. That is equal to 77.50%. So it is also higher than in the previous elections. The findings show that the local government of Pekalongan Regency is more innovative in increasing the political participation of its people.

Published: January 2023

Octavio Paz estuvo interesado en encontrar un símbolo o un mito que fuera la imagen que resumiera su trayectoria poética y vital. Su búsqueda transitó de la metáfora como analogía al símbolo, al mito y al arquetipo. La imagen arquetípica encontrada fue el Mándala. El poema “Nocturno de San Ildefonso” posee una estructura de Mándala, la cual está basada en las figuras geométricas del cuadrado y del círculo, y en los números 1, 2, 3 y 4. “Nocturno de San Ildefonso” es el punto culminante de la trayectoria poética de Octavio Paz. En este poema son importantes los conceptos del ahora, de la presencia y de la transparencia. Asimismo, el sujeto lírico del poema se revela, de acuerdo con el pensamiento del poeta mexicano, como un emisor de símbolos.

El presente trabajo indaga en las posibilidades poéticas de los nombres de lugar como contenedores de la memoria en la obra tardía de Kim Chunsu, uno de los poetas coreanos más representativos del s. XX. Partiendo de la relación fundamental entre ser, lugar y memoria, se explora cómo el topónimo puede, convertido en palabra poética a través de la rememoración y la imaginación, remitir a experiencias biográficas y recrearlas en el poema. Para ello se analizan las imágenes del recuerdo representadas por los topónimos del pueblo natal y el centro de detención de Setagaya que aparecen en su última etapa creativa. Kim Chunsu utiliza estos nombres de lugar con la función de rescatar el recuerdo a través del texto poético, pero establece entre ellos una oposición básica: mientras Tongyeong, el pueblo natal, aparece como un lugar singularizado y atemporal, la prisión de Setagaya se configura como un lugar uniforme e histórico.
EL ROL DEL DEPORTE Y LOS VALORES DEL IDEARIO OLÍMPICO EN LA TRAYECTORIA DEPORTIVA DE ELOÍSA MARCOS QUINTANO
Authors: Astudillo Villamor Iván
Published: January 2023

El trabajo de investigación que fundamenta esta publicación ha tenido como objeto de estudio conocer en qué medida el Olimpismo y su ideario estuvieron presentes en el devenir de la trayectoria deportiva y personal de Eloísa Marcos Quintano, gimnasta española en la década de los años sesenta y setenta, participante en los Juegos Olímpicos de Montreal-1976.

 

La metodología de este trabajo se ha estructurado a partir del análisis documental de la Carta Olímpica (edición 2020) extrayendo los valores que el ideario olímpico manifiesta implícitos en ese documento y contrastar el paralelismo de ese ideario con el esquema conceptual de las funciones que la actividad física y el deporte pueden cumplir, según publicó el profesor Juan L. Hernández Álvarez en Hernández-Álvarez y Velázquez-Buendía (1996). En base al resultado de los análisis documentales mencionados, se ha elaborado la estructura de un guion de una entrevista semiestructurada de final abierto (Hammer y Wildasky, 1990) que fue realizada a la atleta Eloísa Marcos, como fuente primaria oral protagonista de los hechos que pretendíamos rescatar. También se contrastaron los datos del testimonio recogidos en la entrevista con otras fuentes documentales principalmente hemerográficas.

 

Se presentan como resultado, las reflexiones y los análisis de los roles que el deporte desempeñó en la trayectoria deportiva de Eloísa Marcos Quintano, partiendo de los aspectos teóricos que el Ideario Olímpico pretende desempeñar con el deporte practicado a partir de su filosofía, así como, del análisis de cuáles han sido las funciones que en su particular circunstancia, ha desempeñado la actividad deportiva entre las expuestas por Hernández-Álvarez y Velázquez Buendía, (1996).
LA FILOSOFÍA DEL IDEARIO OLÍMPICO Y EL DEPORTE COMO INSTRUMENTO EDUCATIVO EN LA EDUCACIÓN FÍSICA Y EL DEPORTE ACTUAL
Authors: Simancas Romero Jorge
Published: January 2023

El presente artículo se centra en un proyecto monográfico de investigación realizado en torno a un estudio de caso. Con él se pretende conocer si el ideario olímpico como instrumento educativo está presente en la Educación Secundaria y el Bachillerato que se imparte en un Instituto de la Comunidad de Madrid, a través de las enseñanzas impartidas por uno de sus profesores de Educación Física. El diseño metodológico ha partido del análisis documental de la Carta Olímpica con el fin de identificar en ella, como fuente primaria, las bases del ideario olímpico. Tras encontrar los paralelismos que puede tener implícito su contenido con la legislación educativa actual y con las funciones que la actividad física puede desempeñar como instrumento educativo según el planteamiento de Hernández Álvarez (1996), se ha procedido a seleccionar cuatro valores y cuatro funciones como objeto de estudio de este trabajo y se ha procedido a indagar si estos aspectos estaban presentes en el desarrollo de la labor docente del profesor objeto de estudio.

En el presente artículo abordaremos el caso ocurrido con Novak Djokovic en el Open de Australia 2022. Desde una perspectiva ética veremos si su comportamiento ha sido ejemplar, si se adecua a la función pedagógica del deporte, si se vulnera su libertad individual o la legislación de un país democrático como Australia. Apostaremos por la idea de compromiso trascendental recíproco que todo deportista debe asumir cumpliendo las reglas de un deporte y haciendo que su comportamiento personal y profesional sea éticamente aceptable.
Literatura y teatro proletarios
Authors: De Vicente Hernando César
Published: January 2023

Se traza un panorama de la literatura proletaria en la España de la II República de la que deriva la nueva visión que propone la dramaturgia proletaria. Se destacan las reflexiones teóricas establecidas por Ramon J. Sender respecto al teatro proletario señalando cómo España asiste a la aparición de diversas orientaciones artísticas que intentan dar cuenta de los grandes debates del momento. En este sentido es en el que se analizan en el artículo las variantes que podemos encontrar en la literatura izquierdista y que abarcan un gran espectro. Dentro de estas corrientes, conseguir definir qué es y qué defiende la literatura proletaria y en concreto el teatro proletario supone reconocer los intereses de clase que subyacen en la literatura social, la literatura proletaria y la literatura revolucionaria. Así, no se trataría de narrar lo que pasa, en una exposición de hechos, sino de comprender en qué condiciones suceden esos hechos. Cuanto más se aproximen los textos a este objetivo, más cerca estarán de una estética claramente revolucionaria.
Online Education vs Traditional Education: Analysis of Student Performance in Computer Science using Shapley Additive Explanations
Authors: Charytanowicz Małgorzata
Published: January 2023

Nowadays, the rapid development of ICT has brought more flexible forms that push the boundaries of classic teaching methodology. This paper is an analysis of online teaching and learning forced by the COVID-19 pandemic, as compared with traditional education approaches. In this regard, we assessed the performance of students studying in the face-to-face, online and hybrid mode for an engineering degree in Computer Science at the Lublin University of Technology during the years 2019-2022. A total of 1827 final test scores were examined using machine learning models and the Shapley additive explanations method. The results show an average increase in performance on final tests scores for students using online and hybrid modes, but the difference did not exceed 10% of the point maximum. Moreover, the students' work had a much higher impact on the final test scores than did the study system and their profile features.

Biological control is a promising and sustainable strategy to reduce damage caused by agricultural pests and the use of chemical fungicides. Fungal strains of the genus Clonostachys are studied as biocontrol agent of fungi and nematodes. However, the presence of this fungus in the soils of Misiones remains unexplored. Traditional fungal identification is generally carried out by morphological characterization in Petri dishes, and by observing their reproductive structures under the microscope. In general, with this methodology it is possible to identify to the genus level, however determining up to the species level is usually very complicated in some genera and many times ambiguities are achieved. In this context, molecular data emerges as an important tool to complement morphological information and thus achieve a correct fungal identification. The objective of this work was to molecularly identify with ITS markers a strain of the mycoparasitic fungus Clonostachys HEP30. The nucleic acids were isolated for molecular corroboration. From the extracted genetic material, the ITS1-5,8S-ITS2 region was amplified and sequenced. Once the region of interest was obtained, the information obtained was compared with that existing in the databases, using the Blast (Basic Local Alignment Search Tool) of the NCBI (National Center for Biotechnology Information) and the fungal barcoding database and then phylogenetic analysis was done. The molecular identification and phylogenetic analysis allowed us to classify the fungal isolate Clonotachys HEP 30 with high percentage of identity as a member of Clonostachys pityrodes species.

Objective We evaluated the utility of the Korean Modified Early Warning Score (KMEWS), which combines the Modified Early Warning Score (MEWS) and the Korean Triage and Acuity Scale (KTAS), as a triage tool to screen for infection in patients who visit the emergency department.Methods We retrospectively reviewed data extracted from electronic medical records. Patients aged ≥18 years with an infection who were admitted to the hospital via the emergency department between January 2018 and December 2019 were eligible for inclusion. The KMEWS score was calculated as the sum of the KTAS level and the MEWS score. We generated receiver operating characteristic curves and determined the area under the receiver operating characteristic curve (AUC) for the KMEWS, KTAS, MEWS, and Mortality in Emergency Department Sepsis (MEDS) scales. The primary outcome was septic shock, and secondary outcomes were intensive care unit admission and in-hospital mortality.Results The AUC values (95% confidence interval) for predicting septic shock were as follows: KMEWS, 0.910 (0.902–0.918); MEWS, 0.896 (0.887–0.904); KTAS score, 0.809 (0.798–0.819); and MEDS, 0.927 (0.919–0.934). The AUC values (95% confidence interval) for predicting in-hospital mortality were as follows: KMEWS, 0.752 (0.740–0.764); MEWS, 0.717 (0.704–0.729); KTAS score, 0.764 (0.752–0.776); and MEDS, 0.844 (0.834–0.854). The AUC values (95% confidence interval) for predicting intensive care unit admission were as follows: KMEWS, 0.826 (0.816–0.837); MEWS, 0.782 (0.770–0.793); KTAS score, 0.821 (0.810–0.831); and MEDS, 0.839 (0.829–0.849).Conclusion The KMEWS, which is a combination of the MEWS and the KTAS scores, might be a useful triage tool in emergency department patients who present with infection, particularly for predicting septic shock.

Relación entre el desempeño motor real evaluado con pruebas orientadas al proceso y el desempeño motor real evaluado con pruebas orientadas al producto: un metaanálisis
Authors: Jiménez-Díaz Judith , Chaves-Castro Karla , Carpio-Rivera Elizabeth
Published: January 2023

El desempeño motor suele ser evaluado de dos formas; la primera se enfoca en cómo se realiza la destreza, mientras que la segunda registra el resultado obtenido después de la ejecución; ambas son ampliamente usadas, sin embargo, la relación entre ellas no está clara. El objetivo del presente estudio fue determinar la relación entre los resultados de las pruebas orientadas al proceso o al producto utilizadas para medir el desempeño motor real y examinar posibles variables moderadoras por medio de la técnica meta-analítica. Para resumir los resultados, se utilizó el modelo de efectos aleatorios (REML) y se calculó el tamaño de efecto (TE) de correlación. Un total de siete estudios cumplieron con los criterios de elegibilidad, se obtuvo un total de 37 TE. Se encontró que existe una relación significativa y positiva entre el desempeño evaluado por medio de proceso y producto (TE = 0.466; IC95% = 0.391,0.541; p < .001; n = 37; Q = 78.68; p < .001; I2 = 60.17%). Como posibles variables moderadoras se analizó la edad y el tipo de destreza. Los resultados sugieren que existe una relación entre el desempeño motor real evaluado por medio de pruebas orientadas al proceso y al producto, la edad y el tipo de destreza no influyen en dicha relación.
