Published: October 2023

A Good writing is determined by some things, one of which is its process. This study aimed at finding out the influence of the writing process method and a story based on Adab education on the student’s ability to write an opinion essay. The design of this research is mixed method research. The research population was eight classes of undergraduate students in semester 3 of the English Education Department of Teacher Training and Education Faculty in the academic year 2019/2020. The research sample was 37 students that were purposively chosen. The instruments used were a pretest and a posttest. The findings showed that the average posttest score for the experimental class (71.0) was two points higher than the score for the control class (69.0). The results of calculating the difference between the experimental class's posttest and pretest values, a value of 24, were obtained. In contrast, in the control class, a value of 26 was obtained as the result of calculating the difference between the posttest and pretest values. The difference between the two results was -2. Based on that, the conclusion was that the influence of the writing process method and a story based on Adab's education was insignificant. In other words, the writing process method and a story based on Adab education were similarly good in improving students' competence in writing an opinion essay. The findings suggest the necessity of doing or implementing the writing process and a story based on Adab’s education if students hope to have good English writing particularly an opinion essay.

Abstract
During surface-enhanced fluorescence processes, the spatial spacing layer on the surface of noble metals plays an important role in regulating the fluorescence intensity. We propose a method for regulating fluorescence intensity using the AgNPs@TA-FeIII composite nanostructured materials as the substrate and using characteristic fluorescence of graphene quantum dots as the detection signal. Tannins-FeIII (TA-FeIII) nanofilms were prepared with a one-step assembly method, which is simple, fast, green, and safe. This work is expected to help the application of polyphenol metal nanofilm technology in the field of surface enhanced fluorescence (SEF).
Estimación de la distorsión inflacionaria en el valor de libros de las empresas.
Authors: Hauque Fernandez Sergio Miguel 
Published: October 2023

Existe acuerdo respecto que la inflación puede provocar distorsiones que afectan la utilidad de la información contable. En algunos casos, como en el Patrimonio Neto y el Valor de Libros, esas distorsiones pueden resultar potenciadas por la acumulación de varios ejercicios sin ajustes.
El trabajo propone un modelo simplificado para estimar la distorsión del Patrimonio Neto no ajustado en contextos inflacionarios, aproximando su distorsión relativa utilizando una mínima cantidad de variables disponibles en bases públicas de datos. Del modelo surge que esa distorsión no solo depende de los índices generales de precios utilizados para ajustar, sino también de la proporción que representan los activos netos no expresados en moneda de cierre sobre el patrimonio neto sin ajustar.
En una primera aproximación empírica se utilizó una muestra aleatoria de los estados financieros presentados ante la autoridad reguladora chilena al 31 de diciembre de 2021, suponiendo dos escenarios extremos de máxima y mínima distorsión. Los resultados muestran una significativa dispersión de los resultados en ambos escenarios conforme las distintas estructuras patrimoniales observadas en cada caso.
Se abre la posibilidad de afinar este tipo de estimaciones, al mismo tiempo de extenderlas a otras variables como el resultado del ejercicio. Su utilización generalizada permitirá que la decisión de ¿ajustar o no ajustar? sea tomada con más información relevante que el solo dato cuantitativo del índice de inflación
Synthetic Neural Network: Weight Divergence Optimizer
Authors: Mohamed Alwaleed 
Published: October 2023

<p>Any endeavors to explain the network behavior, always falls in the network optimizer explanation trap and gets into the complication of algorithm math operation loop without reaching the final decision of how it really works. Weight divergence optimizer, which is a subcomponent of Synthetic Neural Network explains the inner works of neural network in a pure logical operation using only the dot product multiplication to illustrate this behavior and proposed a formula to calculate bias and weights. The new method uses the network divergence theory instead of trial-and-error method by calculating the maximum variation value between weight and its interior class patterns compared with the minimum variation value of the same weight with exterior patterns of other classes, the difference between the two values used in the formula. Synthetic Neural Network deals with many challenges starting from how Neural Network works and get its result, extending to reducing the size of training dataset, huge memory consumption, extensive processor calculation and creditability. The network output shows a promising result in testing and validation stage, it grants an accuracy of 90% to 75% with two and nine classes when using USPS dataset. Also, it produces accuracy of 95% to71% when using RMNIST expanded with the same classes. In audio patterns with MFCC feature extractions it gives accuracy of 73% with 10 classes. All the training operation performed between 0.5 to 15.5 seconds. The proposed method uses the lowest number of neurons that ever used with two levels of Neural Network, that helps to reduce the network size, discards redundant patterns, removes corrupted inputs and makes the network to converge in a few seconds with the lowest number of input dataset used </p>

Ultisol has main problem of low nutrient availability causing a high percentage of flowers and fruit fall and reducing red chili production. This study aimed to find out effectiveness of biostimulants in reducing percentage of flower and fruit fall, use of inorganic fertilizer doses, and their role in increasing production red pepper in Ultisol. The method used experimental and randomized block design with 9 treatments. The treatment used application of flush biostimulants and without watering into soil with various doses inorganic fertilizers. The fertilizer doses were 100%, 75%, and 50% based on fertilization recommendations. The study results showed that application of biostimulants combined with inorganic fertilizers of various doses had a significant effect on fruit weight/plant and red pepper production, but had an insignificant effect on the percentage of flowers and fruits, as well as number of fruits/plant. Application of biostimulants and various doses of inorganic fertilizers tended to increase fall of flowers, number of fruits/plant, and the percentage of fruit fall. Biostimulants combined with inorganic fertilizers were able to reduce fertilizer use as much as 50%. Production of red pepper with application of biostimulants and 50% of inorganic fertilizers reached 5.36 tons/ha. The results of the economic feasibility analysis of red chili peppers were 1.69 R/C and 0.69 B/C ratio, meaning that the cultivation of red chili with application of biostimulants was profitable and worthy of development. So, application of biostimulants is able to reduce fertilizers by 50% and increase production of red peppers.

Published: October 2023

Introduction: Hypertension and hypothyroidism are common problems in the community. Although the hypothyroidism prevalence in people with hypertension has been reported, there are limited studies about hypertension prevalence in hypothyroid patients. This study aimed to analyze the prevalence and age of hypertension among patients with overt primary hypothyroidism in a tertiary care center in India.
Methods: A descriptive cross-sectional study was conducted among hypothyroid patients who consecutively attended a tertiary care hospital in Karnataka, India from 1 November 2020 to 30 September 2021. Purposive sampling method was used. Data was tabulated in MS Excel version 16 and analyzed via Statistical Package for Social Sciences (SPSS) Version 20.0.
Results: A total of 520 overt primary hypothyroid patients with 141 (27.1%) men and 379 (72.9%) women were included in the study. The mean age of the hypothyroid patients was 52.20 ± 16.414 years, with 58.27 ± 17.339 years of male and 49.95 ± 15.483 years of female (p < 0.05). The prevalence of hypertension among total hypothyroid patients was 225 (43.3%) (39-47.54, 95% CI) with 77 (54.61%) (46.29-62.93, 95% CI) in men and 148 (39.1%) (34.12-43.98, 95% CI) in women (p < 0.05). The mean age of patients with hypertension was 59.97 ± 13.218 years, with 65.39 ± 11.642 years of male and 57.15 ± 13.144 years of female (p < 0.05). 2
Conclusions: The prevalence of hypertension in hypothyroid patients was similar to prevalence in the general population and was higher in males than in females. The gender-wise distribution of patients with hypertension among hypothyroidism was more in females due to the high proportions of female in patients with hypothyroidism.
The role of visual crowding in eye movements during reading: Effects of text spacing
Authors: Chiu Tzu-Yao , Drieghe Denis 
Published: October 2023

AbstractVisual crowding, generally defined as the deleterious influence of clutter on visual discrimination, is a form of inhibitory interaction between nearby objects. While the role of crowding in reading has been established in psychophysics research using rapid serial visual presentation (RSVP) paradigms, how crowding affects additional processes involved in natural reading, including parafoveal processing and saccade targeting, remains unclear. The current study investigated crowding effects on reading via two eye-tracking experiments. Experiment 1 was a sentence-reading experiment incorporating an eye-contingent boundary change in which reader’s parafoveal processing was quantified through comparing reading times after valid or invalid information was presented in the parafovea. Letter spacing was jointly manipulated to compare how crowding affects parafoveal processing. Experiment 2 was a passage-reading experiment with a line spacing manipulation. In addition to replicating previously observed letter spacing effects on global reading parameters (i.e., more but shorter fixations with wider spacing), Experiment 1 found an interaction between preview validity and letter spacing indicating that the efficiency of parafoveal processing was constrained by crowding and visual acuity. Experiment 2 found reliable but subtle influences of line spacing. Participants had shorter fixation durations, higher skipping probabilities, and less accurate return sweeps when line spacing was increased. In addition to extending the literature on the role of crowding to reading in ecologically valid scenarios, the current results inform future research on characterizing the influence of crowding in natural reading and comparing effects of crowding across reader populations.

Published: October 2023

La ingestión de un cuerpo extraño complicada con perforación del tracto digestivo es un hecho bien conocido. Aproximadamente entre el 80-90% de los cuerpos extraños ingeridos pasan por el tracto gastrointestinal sin ser detectados, expulsándose en promedio en el lapso de una semana, entre el 10-20% requieren extracción por vía endoscópica y aproximadamente el 1-4% ocasionan obstrucción o perforación intestinal requiriendo remoción quirúrgica; Sin embargo existen raras ocasiones en las que la perforación no genera sintomatología y el cuerpo extraño migra a otros sitios, siendo lo más común la invasión a estructuras del cuello y en muy pocos casos intraabdominal, el hígado es uno de los órganos involucrados. Donde pueden actuar produciendo respuesta inflamatoria local y como medio de colonización de microorganismos produciendo en ocasiones la formación de un absceso intrahepático y en última instancia trombosis de la vena porta.

Aim. TIntroduction. To evaluate in-hospital angiographic and five-year posthospital clinical outcomes of percutaneous intervention strategy without stent implantation with immediate coronary artery stenting technique in STEMI patients with massive coronary thrombosis.Material and methods. The study enrolled 116 patients with primary STEMI myocardial infarction with the signs of massive thrombosis in the lumen of the main epicardial coronary artery with TIMI thrombus grade greater than 3 after antegrade blood flow restoration. In the 1st group of delayed intervention at the primary stage the blood flow was restored by small diameter balloon inflation and/ or manual vacuum thrombus aspiration until stable TIMI grade 3 blood flow was achieved, at control CAG on day 5-6 in 36 people the stent was not implanted due to insignificance of infarct-related coronary artery stenosis (stenosis less than 50% according to QCA). Immediate stent implantation was performed in 78 patients (group 2). The primary endpoint was the incidence of adverse cardiovascular events, including total mortality, recurrent myocardial infarction, repeated revascularization of the infarct-responsive artery. Secondary endpoint: frequency of achieving optimal myocardial perfusion as measured by angiography – TIMI blood flow and Myocardial Blush Grade.Results. The median follow-up period was 47 months. The incidence of the primary end point (MACE) was 15,8% in group 1 and 23,1% in group 2, with no statistically significant difference (p=0,408). Overall mortality (10,5% and 11,7%), the rate of repeat myocardial infarction (2,6% and 5,1%), and the rate of repeat target vessel revascularization (2,6% and 6,4%) were without significant advantage between subgroups. Optimal reperfusion (TIMI-3 and Myocardial Blush Grade 2-3 after primary procedure was achieved in significantly (p=0,02) more patients in group 1 (89%) than in group 2 (69,2%) ST segment resolution ≥70% after intervention was achieved in 87% of cases in group 1 and in 64,1% of cases in group 2 (p=0,011).Conclusion. In STEMI patients with massive coronary thrombosis, the method of delayed percutaneous intervention increases the rate of achieving optimal blood flow and allows avoiding stent implantation in the infarct-related artery in 50% of cases as compared to the method of immediate stenting. Both methods have comparable hospital and five-year clinical risks.
